Description

Technical Field

[0001] The invention belongs to the field of automation equipment and relates to a circulation mechanism in an automatic assembly line of a water distributor. Background Art

[0002] The existing water distributor pipes need to be installed with parts such as valve seats, valve stems, balls and water outlets. The existing installation methods all adopt manual installation, which has low production efficiency and requires a lot of manpower.

[0003] In response to the above problems, people have developed various equipment and fixtures for the assembly of water distributor pipe fittings, and some have even applied for patents. For example, Chinese patent literature discloses a water distributor pipe body assembly fixture [application number CNCN201921797248.X], which includes a fixed seat, on which two side plates are fixed, a guide shaft is fixed between the left plate and the right plate, a movable splint is installed on the guide shaft, a return spring is sleeved on the guide shaft between the movable splint and the right plate, and a quick clamp is fixed between the movable splint and the left plate; horizontal support teeth are staggered and fixed at the lower part of the movable splint and the right plate, a vertical opening splint for fixing the water distribution pipe main pipe is provided facing each other at the middle part of the movable splint and the right plate, and a horizontal opening splint for fixing the water distribution outlet of the water distributor is provided facing each other at the upper part of the movable splint and the right plate.

[0004] The above-mentioned water distributor pipe body assembly fixture uses a quick clamp to achieve the clamping and loosening of the movable clamp and the right side plate, which improves work efficiency and reduces the operating burden of personnel. However, the work efficiency is not significantly improved, and manual assembly is still required, and the labor cost of personnel is not reduced. Summary of the invention

[0005] The purpose of the present invention is to provide a circulation mechanism in an automatic assembly line of a water distributor to solve the above problems existing in the prior art.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A circulation mechanism in an automatic assembly line for a water divider, comprising a control system, a workbench, a plurality of tooling trolleys arranged in sequence in a front and rear row, and two pushing mechanisms for pushing the two rows of tooling trolleys to move laterally, characterized in that a track changing mechanism 1 for pushing the corresponding tooling trolley to move to the rear row and complete the track change is provided on one side of the front-row tooling trolley, and a track changing mechanism 2 for pushing the corresponding tooling trolley to move to the front row and complete the track change is provided on the other side of the rear-row tooling trolley. The plurality of tooling trolleys move cyclically in a rectangular trajectory under the control of the control system, the track changing mechanism 1, the track changing mechanism 2 and the pushing mechanism, a slide table that can move laterally is provided on the workbench between the two rows of tooling trolleys, a plurality of locking devices for fixing the rear-row tooling trolleys and capable of moving forward and backward are installed on the slide table, and a plurality of positioning units for positioning the rear-row tooling trolleys and capable of moving forward and backward are installed on the rear side of the rear-row tooling trolley on the workbench.

[0007] In the circulation mechanism in the above-mentioned automatic assembly line of water distributors, the front and rear side walls of several tooling carts are provided with snap-in interfaces, the locking device is provided with a snap-in portion 1 for snap-in fixing the rear-row tooling carts, and the snap-in portion 1 is matched and connected with the snap-in interfaces on the rear side walls of the several tooling carts, and the positioning unit is provided with a snap-in portion 2 for snap-in positioning the rear-row tooling carts, and the snap-in portion 2 is matched and connected with the snap-in interfaces on the front side walls of the several tooling carts.

[0008] In the circulation mechanism in the above-mentioned automatic assembly line of the water distributor, the clamping connection between the clamping part one, the clamping part two and the clamping interface can adopt a serrated clamping structure; the clamping connection can adopt a concave-convex clamping structure; the clamping connection can adopt a stepped clamping structure; the clamping connection can also adopt an inner and outer arc clamping structure.

[0009] In the circulation mechanism in the above-mentioned automatic assembly line of water distributors, the locking device is composed of a fixed block and a cylinder for driving the fixed block to move forward and backward, the clamping part is located on the side wall of one end of the fixed block, and the positioning unit is composed of a connecting block and a cylinder for driving the connecting block to move forward and backward, and the clamping part is located on the end face of the connecting block.

[0010] In the circulation mechanism in the above-mentioned automatic assembly line of water distributors, the two driving mechanisms can use a numerically controlled screw nut to drive the tooling trolley to move horizontally, or can use a cylinder to drive the tooling trolley to move horizontally.

[0011] In the circulation mechanism in the above-mentioned automatic assembly line of water distributors, the track changing mechanism 1 and the track changing mechanism 2 are both composed of a movable track for the movement of the tooling trolley, a mounting plate for installing the tooling trolley and driving the tooling trolley to move, and a pushing cylinder for driving the tooling trolley to move.

[0012] Compared with the prior art, the circulation mechanism in the automatic assembly line of the water distributor has the following advantages:

[0013] 1. This circulation mechanism is equipped with a track-changing mechanism on both the front and rear rows of tooling trolleys. The track-changing mechanism realizes the linkage of the front and rear rows of tooling trolleys, forming a complete circulation track, realizing continuous assembly and production to the greatest extent, and improving assembly efficiency;

[0014] 2. In this circulation mechanism, a clamping interface is provided on both side walls of the tooling trolley, and the positioning and movement of the tooling trolley are controlled by the locking device and the clamping part on the positioning unit, which effectively prevents the displacement of the water distribution pipe during assembly and the free sliding of the tooling trolley when the tooling trolley is moved;

[0015] 3. This circulation mechanism has two driving mechanisms with independent driving frequencies, which can not only meet the needs of continuous and frequent positioning and assembly of the rear tooling trolley, but also meet the needs of unloading the finished water distributor and replacing the main rod of the water distributor by the front tooling trolley;

[0016] 4. The circulation mechanism has a reasonable structural design, high assembly efficiency, short cycle, and no human intervention, which greatly reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

One extra tooling trolley 2 is located in the track changing mechanism 4, which is used to connect the front and rear rows of tooling trolleys 2 to form a complete circulation loop. The assembly of the water divider requires 4 independent assembly processes.
