Embodiment 1

[0049] Such as figure 1 , figure 2 and Figure 10 As shown, a processing system for a three-pin shaft universal joint in this embodiment includes three components: a loading and unloading unit 1, a grasping and positioning unit 2, and a clamp unit 3. The loading and unloading unit 1 is used for three The pin-type universal joint 4 is transported, and the grabbing and positioning unit 2 grabs the tripod-type universal joint 4 and sends it to the clamp unit 3 for processing. Such as Figure 4 As shown, the clamp unit 3 includes a clamp mounting plate 301, a positioning convex ring 311, a positioning concave ring 312, a mandrel 309, a first driving mechanism and a second driving mechanism, and the positioning convex ring 311 is fixedly installed on the clamp mounting plate 301, the positioning concave ring 312 is located above the positioning convex ring 311 and is engaged with it. One end of the mandrel 309 is provided with an elastic expansion sleeve 313, and the other end ...

Embodiment 2

[0054] The structure of the processing system of a three-pin shaft universal joint in this embodiment is basically the same as in Embodiment 1, the main difference is that the grasping and positioning unit 2 includes two air grippers 205 and a positioning block 211, such as Figure 7 As shown, the two air claws 205 are installed on the rotary plate 213 through the second rotary cylinder 203 and the third rotary cylinder 204 respectively, and the second rotary cylinder 203 and the third rotary cylinder 204 respectively control the movement of the air claws 205 connected thereto. Rotation; the rotating plate 213 is installed below the cantilever crane 201 through the first rotating cylinder 202, and the rotating plate 213 is driven to rotate by the first rotating cylinder 202, thereby controlling the rotation of the second rotating cylinder 203 and the third rotating cylinder 204; by using The second and third rotary cylinders control their corresponding air claws 205 to grab the...

Embodiment 3

[0059] The processing system of a three-pin shaft type universal joint in this embodiment is basically the same in structure as in Embodiment 2. When using this processing system for processing, it specifically includes the following steps:

[0060] Step 1. Put multiple three-pin universal joints 4 into the discharge pipe 105 of the loading and unloading unit 1, and drive the L-shaped push plate through the telescopic cylinder 108 to push the three-pin universal joints 4 to the discharge conveyor belt 103, transport it to the discharge conveyor belt 103 front end contact stop block 115 and wait for the grasping and positioning unit 2 to grasp and process after it stops; Grabbing and processing, the follow-up tripod-type universal joint 4 will be stopped by the stop cylinder 109 until the front tripod-type universal joint 4 is grabbed and processed, and the subsequent adjacent tripod-type universal joints The knuckle 4 will not move until the stop block 115 stops and waits to b...

Abstract

The invention discloses a processing system for a tripod-type universal joint, which belongs to the technical field of universal joint production. It includes a loading and unloading unit, a grabbing and positioning unit, and a fixture unit. By optimizing the design of the fixture unit, a mandrel is set on the fixture unit, and the three-pin universal joint and the positioning concave ring are placed on the mandrel by the first driving mechanism. The upper expansion is fixed, and then the second driving mechanism is used to push out the three-pin universal joint and the positioning concave ring to change the direction. Through the coordinated installation of the positioning convex ring and the positioning concave ring, the centering and positioning problems in the traditional method are solved. The problem of inaccurate reversing angle has effectively improved the accuracy of the centering and reversing angle during the processing of the three-pin universal joint, reduced the error, improved the accuracy of the product, and improved the automation compared with the manual operation method. To a certain extent, the labor intensity is reduced, the cost is also reduced, the production efficiency is effectively improved, and the safety of the staff is also guaranteed.

Description

technical field [0001] The invention belongs to the technical field of universal joint production, and more specifically relates to a processing system for a tripod-type universal joint. Background technique [0002] With the development of industry, the types of mechanical equipment are constantly updated and developed, and the development of universal joints is also constantly updated. Various universal joints appear in people's lives and are used in various production equipment. The universal joint is the universal joint, which is a machine that realizes variable-angle power transmission. It is used to change the position of the transmission axis direction. It is the "joint" part of the universal transmission device of the automobile drive system. The combination of universal joint and transmission shaft is called universal joint transmission. [0003] There are many types of universal joints, such as cross-axis universal joints, double-joint universal joints, three-pin ...
