Abstract:
Marking machine with fixed motors, said machine comprising: for the OX axis, a first electric and fixed motor (2), means (23) for transmitting its motion to a first head (22) sliding on a first guide (21); a support (3) integral with said first head (22) and with a second guide (11); for the OY axis, a second electric and fixed motor (1), means for transmitting the motor's motion to a working head (P) which slides on said second guide (11); the first (2) and second (1) motors being controlled so as to create a differential motion between the two motors which is sufficient to effect the displacement on the OY axis. Application to the marking of materials by deformation.
Abstract:
A multi-tool positioning and manufacturing system moves a workpiece among many tools, such as grinding wheels, each of which performs a manufacturing operation on the workpiece. The system moves the workpiece automatically, quickly, repeatably, and precisely among the tools, without any manual intervention. It can perform the same manufacturing operations as many separate tools, such as grinding the inner diameter, outer diameter, and rib of a tapered roller bearing cone. Because a machinist does not have to move the workpiece between machines for different operations, the total manufacturing process can be faster and higher yield than with separate tools. The system can also move a single dresser among the tools for dressing and truing, further increasing manufacturing efficiency by eliminating the need for separate dressers for separate tools.
Abstract:
A mounting fixture (10) for positioning a workpiece (4) in a desired re¬ relationship with an apparatus (6) including an articulation joint (20) for coupling first (12) and second (14) tubular members in a desired angular relationship. The articulation joint includes a first end portion clamped to an interior surface of the first tubular member and a second end portion clamped to an interior surface of the second tubular member. First and second clamping members (40a, 40b) of the articulation joint are clamped together to prevent pivotable movement between a first articulation member (22a) and a second articulation member (22b) of the articulation joint.
Abstract:
A double-rotatable spindle head with non-perpendicular axes for machine tools, with a first half-head (2) pivoted to the machine structure (4) about a first axis (10) and, for supporting the tool spindle (8), a second half-head (6) coupled to the first half-head (2) on a flat surface (20) and pivoted to it about a second axis (22) perpendicular to said flat surface (20), characterised in that said flat surface (20) forms with said first axis (10) an angle less than 45 DEG and preferably between 35 DEG and 40 DEG .
Abstract:
An assembly (100) comprises a parallel robot (101) and a servo spindle (102). The parallel robot (101) is adapted to be mounted onto a platform (300) under the mechanical part (33) to be machined and includes one or more axes. The servo spindle (102) is mounted on the parallel robot (101) and configured to drive a machining tool (103) to rotate. The parallel robot (101) is configured to drive the servo spindle (102) to translate along one or more axes relative to the parallel robot (101). The machining tool can cut the desired shapes at a bottom of the mechanical part. In this way, the flexibility and efficiency of machining can be improved under the condition of meeting the machining accuracy. An apparatus and a method for machining a mechanical part are further disclosed.
Abstract:
An object (85) to be transferred supported by an object supporting means (40) is displaced vertically while varying the orientation of the object (85) without moving a mover (10) by turning the supporting means (40) about a longitudinal axis (39) through a rotary operating means (30). Since the travel distance is not required to displace the object (85) vertically, processing part (processor) of the object (85) can be reduced in length and size. Furthermore, various kinds of processing can be carried out smoothly and suitably without producing any adverse effect on the surroundings by varying the orientation of the object (85).
Abstract:
The invention relates to a positioning device (1) for positioning a workpiece (2) with a stand (5), which can be placed on a base (4), and a positioning table (11), on whose upper side the workpiece (2) can be directly or indirectly placed. The positioning table (11) can be arranged relative to the base (5) linearly and/or rotatory in at least two positions on planes defined by the upper side of the positioning table (11). Movement of the positioning table in a given direction occurs via at least two fine adjustment devices (15, 16) which are supported directly or indirectly by the base (5) and to which a driving force can be transferred, in particular by hand. In addition to being powered by the fine adjustment apparatus (15, 16), the positioning table (11) can also be powered by a driving force in particular a manual force which indirectly impinges on the positioning table (11), in particular by hand, with the purpose of effecting a rapid rough adjustment of the position of the table.
