DETAILED DESCRIPTION

[0021] As attached Figure 1-6 Shown

[0022] The processing device of the universal joint fork expansion joint includes a base plate 1, a push piece and a cutting piece. The base plate 1 is a rectangular plate. A positioning block 2 is fixedly installed on the base plate 1. The positioning block 2 is a rectangular block. A first clearance groove 3 is arranged in the middle position of the positioning block 2. The first clearance groove 3 is arranged corresponding to the push piece.

[0023] A slide rail 4 is symmetrically arranged on the bottom plate 1 on one side of the positioning block 2. The cross-section of the slide rail 4 is an inverted isosceles trapezoid. A sliding member is slidably installed on the slide rail 4. The sliding member includes a slider 5 and a positioning tube 6. The slider 5 is a rectangular block. Dovetail grooves 7 are arranged at corresponding positions of the slider 5 and the slide rail 4. The dovetail groove 7 of the slider 5 is slidably connected with the slide rail 4. When in use, the slider 5 can slide along the axial direction of the slide rail 4.

[0024] A positioning tube 6 is provided at the front end of the slider 5. The positioning tube 6 is used to be inserted into the second assembly hole 20 of the universal joint fork 18 to position the universal joint fork 18. The positioning tube 6 and the upper end of the slider 5 are respectively provided with cutting clearance grooves 8. The cutting clearance grooves 8 of the positioning tube 6 and the slider 5 are interconnected. A workpiece positioning groove 9 is provided on the slider 5 at the connection between the positioning tube 6 and the slider 5. The workpiece positioning groove 9 is used to position one end of the universal joint fork 18 to prevent the universal joint fork 18 from sliding when processing the expansion joint 22.

[0025] A tension spring 10 is symmetrically arranged between the sliding member and the positioning block 2. A second make way groove 21 is arranged at the corresponding position of the positioning block 2 and the tension spring 10. The second make way groove 21 is used to make way for the tension spring 10. One end of the tension spring 10 is fixedly connected to the inner wall of the second make way groove 21, and the other end of the tension spring 10 is fixedly connected to the outer surface of the slider 5. When in use, under the tension of the tension spring 10, the slider 5 has a tendency to move toward the positioning block 2.

[0026] A pushing member is installed on the base plate 1 on one side of the positioning block 2, and the pushing member includes a pushing cylinder 11, a cylinder fixing plate 12 and a pushing head 13. The cylinder fixing plate 12 is fixedly installed on the base plate 1, and the pushing cylinder 11 is fixedly installed on the cylinder fixing plate 12. A pushing head 13 is fixedly installed on the piston head of the pushing cylinder 11. The pushing head 13 is rectangular and has an arc groove 14 in it. The arc groove 14 of the pushing head 13 corresponds to the first yielding groove 3 of the positioning block 2.

[0027] A cutting piece is installed on the base plate 1 on one side of the slider 5, and the cutting piece includes a rotating motor 15, a motor mounting plate 16 and a cutting disc 17. The motor mounting plate 16 is fixedly installed on the base plate 1, and the rotating motor 15 is fixedly installed on the motor mounting plate 16. The cutting disc 17 is fixedly installed on the transmission shaft of the rotating motor 15, and the cutting disc 17 is arranged corresponding to the cutting clearance groove 8.

[0028] When the processing device of the universal joint fork expansion joint is used, the staff first pulls the slider 5 outward, so that the slider 5 slides to the right along the axial direction of the slide rail 4, and the slider 5 is out of contact with the positioning block 2. During this process, the tension spring 10 is stretched and energy is stored.

[0029] Then the staff puts the universal joint fork 18 to be processed into the first clearance groove 3 of the positioning block 2. The first clearance groove 3 plays a guiding and positioning role for the universal joint fork 18, so that the second assembly hole 20 of the subsequent universal joint fork 18 is aligned with the positioning tube 6. Before the universal joint fork 18 is placed into the first clearance groove 3, the rectangular end of the universal joint fork 18 corresponds to the workpiece positioning groove 9 of the slider 5. The purpose of such setting is to facilitate the matching of the arc groove 14 of the subsequent pushing head 13 with the arc-shaped end of the universal joint fork 18.

[0030] After the universal joint fork 18 is placed, the slider 5 is released. Since the tension spring 10 is stretched and stores energy, the slider 5 slides to the left along the axial direction of the slide rail 4 under the elastic force of the tension spring 10 until the slider 5 approaches the positioning block 2 and contacts the positioning block 2. At this time, the positioning tube 6 at the front end of the slider 5 is inserted into the second assembly hole 20 of the universal joint fork 18.

[0031] In this way, one end of the universal joint fork 18 with a rectangular shape is clamped in the workpiece positioning groove 9 of the slider 5. During this process, since the slider 5 has a tendency to move toward the positioning block 2, under this tendency, the slider 5 pushes the universal joint fork 18 to move to the left along the first give way groove 3 of the positioning block 2 until the arc-shaped end of the universal joint fork 18 corresponds to and contacts the arc groove 14 of the pushing head 13, thereby allowing the positioning block 2 and the pushing head 13 to clamp the universal joint fork 18.

[0032] When the yoke 18 is clamped left and right by the push head 13 and the slider 5, the piston rod of the push cylinder 11 is started to extend outward, and the push head 13 pushes the yoke 18 and the sliding member to move right synchronously. During this process, under the tension of the tension spring 10, the push head 13 and the sliding member always maintain a clamping state for the yoke 18.

[0033] The rotary motor 15 is started, and the rotary motor 15 drives the cutting disc 17 to rotate. When the cutting disc 17 enters along the cutting clearance groove 8, the cutting disc 17 cuts an expansion joint 22 on the universal joint fork 18.

[0034] When the expansion joint 22 of the universal joint fork 18 is cut, the piston rod of the control push cylinder 11 is reset, and then the slider 5 is pulled outward so that the slider 5 slides to the right along the axial direction of the slide rail 4, and the universal joint fork 18 with the expansion joint 22 cut out is removed, thereby completing the processing operation of the expansion joint 22 of the universal joint fork 18, replacing the next universal joint fork 18 to be processed, repeating the above operation, and the processing operation of the expansion joint 22 of the universal joint fork 18 can be started in a cycle.

[0035] The processing device for the expansion joint of the universal joint fork can conveniently and quickly position the universal joint fork 18 through the first yield groove 3 of the positioning block 2, and can clamp the universal joint fork 18 through the cooperation of the slider 5, the positioning tube 6, the tension spring 10 and the push head 13, thereby avoiding the problem of workers' fingers being cut when manually holding the universal joint fork for expansion joint processing; the slider 5, the positioning tube 6, the tension spring 10, the push head 13 and the universal joint fork 18 are pushed to the bottom of the cutting piece by the piston rod of the pushing cylinder, and the cutting disc 17 is used to cut an expansion joint 22 on the universal joint fork 18, thereby ensuring the consistency of the cutting of the expansion joint 22 on the universal joint fork 18, which is very suitable for the processing operation of the expansion joint of the enterprise's universal joint fork.
