Abstract:
A circulating element for ball screw includes a first surface defining a circulating passage that extends from one lateral side of the first surface to the other lateral side of the first surface and has a coupling mouth located on each of the two opposite ends thereof, and a second surface defining a coupling groove between the two coupling mouths of the circulating passage and two guide blocks respectively protruding out of the coupling mouths of the circulating passage. Thus, the circulating element has the advantages of low processing cost, ease of installation, high alignment accuracy, and excellent running smoothness.
Abstract:
Ball screw nut is composed of an inner threaded nipple and an outer housing. The nipple is constructed with a hollow hard tubular metallic material to ensure the strength of the structure; while the outer housing where requires less strength is formed of a plastic material by ejection mold process so as to reduce the production cost and simplify the fabrication process. The nipple and the housing are conjoined together by screw engagement.
Abstract:
A method for identifying installation positions of sensors, which predefines the corresponding relationship between the first sliding member, the second sliding member and the signal features according to the installation directions of the sensors, and then drives the first sliding member and the second sliding member of one of the feed systems to move to obtain and analyze the three-axis signals fed back from the sensors, firstly select responsive three-axis signals, and then determine the axis with the largest response of the three-axis signals so as to identify the sensor installed on the first sliding member. Then, the corresponding relationship between the remaining three-axis signals and the sensors installed on the second sliding members is identified based on the dynamic signal feature and the static signal feature, so as to achieve the purpose of automatically identifying the installation position of the respective sensors.

The mapping device includes: a first sensor group defining a first optical axis, and adapted to be disposed at a front side of the container to move in the detecting direction for detecting the test objects; and a second sensor group defining a second optical axis, and adapted to be disposed at the front side of the container to move in the detecting direction for detecting the test objects. The second optical axis is inclined relative to the first optical axis, and is disposed ahead of the same in a front-rear direction of the container and at a downstream side of the same in the detecting direction.
Abstract:
An inner circulation ball screw includes a screw shaft, a nut, and a return member. The nut is disposed on the screw shaft to form a load path with the screw shaft. The return member is disposed in an accessory slot of the nut to form a non-load path connected with the load path to form a circulation path for circulation of balls. The return member has a ball-discharging channel provided with one end connected with an ineffective thread section of the nut and the other end communicating with a ball-discharging hole of the nut. Therefore, the balls are allowed to move to the outside of the nut through the ball-discharging channel and the ball-discharging hole for preventing the balls from being stuck in the ineffective thread section, thereby solving the problems of high resistance and damaging to related accessories.
Abstract:

Abstract:
A method and a system for building digital twin models allow the setting of a shape and dimensions of a simplified geometric solid corresponding to a component of a feeding system; after sampling the solid to obtain second position data, calculates a set of model eigenvalues and a set of model eigenvectors by a modal analysis method according to a material data of the component, the second position data and second size data of the solid; and defines the solid as a digital twin model of the component when it is determined by a modal verification method that a set of actual eigenvectors of the component is similar to the set of model eigenvectors. Data amounts of the second position and size data are far less than data amounts of first position and size data of an image of the component.
