Problems solved by technology
[0005] The disadvantages of the above-mentioned switching system: the above-mentioned technology has many buttons, which increases the cost and the error rate of employees, and the operation of switching models is cumbersome and prone to operational errors; the switching system needs to restore all the fixtures to their original state before each switching , to prevent interference between fixtures between two different models, this operation is called signal clearing
After a complete set of operation process is completed, the fixture will be restored to its original state. However, when an accident occurs, the above-mentioned technology has no automatic reset measures, and the process can only be manually re-operated to restore the state of the fixture.

Embodiment Construction
[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0034] Such as figure 2 As shown, the cam combination structure 1 includes: a rotating shaft 11, a multi-directional cam 12 fixed on the rotating shaft 11, a plurality of one-way cams 13 fixed on the rotating shaft 11; the one-way cam 13 has a protruding portion 131, The multidirectional cam 12 has a plurality of protruding parts 121 distributed along the circumferential direction of the rotating shaft 11, the number of the protruding parts 121 of the multidirectional cam 12 is consistent with the number of the one-way cams 13 on the rotating shaft 11, and the multidirectional cam 12 The protrusions 121 of the one-way cam 13 and the protrusions 131 of the one-way cam 13 are alternately distributed. The staggered distribution here means that the phase of the protruding portion 131 of a one-way cam 13 is located between two adjacent protruding...

The invention provides a cam combined structure which comprises a rotating shaft, a multidirectional cam fixed on the rotating shaft, and a plurality of unidirectional cams fixed on the rotating shaft; each unidirectional cam is provided with a protruding portion, the multidirectional cam is provided with a plurality of protruding portions distributed in the circumferential direction of the rotating shaft, the protruding portions of the multidirectional cam are the same as the unidirectional cams on the rotating shaft in number, and the protruding portions of the multidirectional cam and the protruding portions of the unidirectional cams are distributed in a staggered mode. The cam combined structure enforces system zero clearing before vehicle type switching at each time, and reduces operation hidden danger.
Description
technical field [0001] The invention relates to an automobile control system, in particular to a cam combination structure. Background technique [0002] Welding fixture is an auxiliary tool in the production of automobile body-in-white. It accurately positions and fixes the workpiece at a specified position. The commonly used fixture mainly controls its clamping or opening state through a pneumatic system. [0003] In order to improve the use efficiency of the fixture, a kind of fixture that can be used for various car models is often used. The design of the pneumatic system of the fixture is directly related to the operability and safety of the whole set of fixtures. Such as figure 1 As shown, R2, R3, and R4 are the three vehicle types that the fixture needs to meet, corresponding to signal interfaces B, A, and E, respectively, and signal interface C corresponds to the shared fixture of R2 and R3. Among them, the momentary signal valve 5 sends a momentary signal to the p...
