摘要:
An automated parts assembly station includes positioning means (11) having surfaces (15a, 16a) for defining a desired mutual position of the parts to be assembled and assembly means (13) connecting the parts. At some of the surfaces (15a, 16a) there are measurement means (18) for measuring a distance between the surfaces and facing surfaces of the parts being assembled. A method is provided for the timely detection of the assembly tolerances. The method includes the steps of performing with the positioning means a permanent positioning of the parts being assembled, operation of the assembly means for connecting the parts, and releasing of the positioning means. Additionally, there is a measurement of the distance between the assembled parts and some of the surfaces. This measurement includes a comparison of the measured distances with maximum admissible distances. At the end, the method generates an acceptance or non-acceptance signal depending on whether the distances measured are greater or less than the related maximum admissible distances.

Automated parts assembly station includes positioning member (11) having surfaces (15a, 16a) defining a desired mutual position of the parts to be assembled and assembly member (13) connecting the parts. At at least some of the surfaces (15a, 16a) there are measurement members (18) for measuring a distance between the at least some surfaces and facing surfaces of the parts being assembled.
摘要:
A welding electrode dressing device in particular in automated welding stations comprises an electrode treatment head (11, 111) equipped with upsetting members (15, 115) which reshape the tip of an electrode inserted in it without removing material. Advantageously the treatment head (11, 111) comprises two treatment seats (19, 119) arranged on opposite sides thereof to each receive the end (12) of a pair of welding gun electrodes.

A motor vehicle body assembly and welding station comprises a pair of facing tool (12) support conformators (11) designed to work on the body and taken between them by a conveyor system (14). The conformators are movable between a rest position in which the body is free to enter and exit the station and a work position in which the tools are near the body to work on it. At least some of the tools (12) comprise measurement means (20) for the relative position of facing body parts and the conformators have an intermediate position between said work and rest positions. On command control means (19) take the conformator into said intermediate position and activate the measurement means (20) to determine the agreement of body dimensions with predetermined measurement intervals and issue acceptance or rejection signals (22) for the body on the basis of the survey result.
