Description

Technical Field

[0001] This utility model relates to the field of door lock parts processing, and in particular to the field of riveting self-locking technology, specifically a riveting self-locking tooling structure for door lock linkage products. Background Technology

[0002] For products with structures at both ends of the rivet, when riveting a single end, the part that does not need to be riveted needs to be clamped with an openable clamping fixture to ensure that the diameter of the non-riveted area does not increase due to the material flow during the riveting process. At the same time, the end face of the clamping fixture after closing also needs to serve as the support surface for riveting.

[0003] Traditional clamping fixtures are directly clamped by means of hydraulic cylinders or pneumatic cylinders through electronic control. Because the medium inside the cylinders is compressible, a larger cylinder body is required to ensure that the fixture does not move to the sides during processing, which leads to an increase in the diameter of the non-riveting area.

[0046] This utility model proposes a self-locking fixture structure for riveting door lock linkage products. It is used in the riveting process of door lock accessory linkages. This utility model does not impose specific restrictions on the specifications of the linkages to be riveted, but the structure of the positioning module 2, drive module 3 and linkage locking module 4 is particularly suitable for the door lock linkage riveting process.

[0047] In general, the self-locking fixture structure for riveting door lock linkage products proposed in this utility model mainly includes: a clamp base 1, a positioning module 2, a drive module 3, and a linkage locking module 4. (See also...) Figure 1 It shows the arrangement of the clamp base 1, positioning module 2, drive module 3 and linkage locking module 4.

[0048] The self-locking fixture structure for riveting door lock linkage products proposed in this utility model includes the following workflow:

[0049] S1: Place this tooling on the processing platform of the riveting machine, align the riveting head 5 with the riveting post hole 22 in the riveting machine, and fix the wedge block 31 to the main shaft, which serves as the lifting structure of the riveting machine, through the connecting rod 36.

[0050] S2: Place the bottom connecting rod body of the workpiece with the rivet pin into the workpiece placement slot 23 on the side of the tooling block 211, with the top rivet pin against the rivet pin hole 22, and start the riveting machine.

[0051] S3: The wedge block 31 and the rivet head 5 move down simultaneously, as... Figure 2The bottom surface of the wedge block 31 shown is lower than the rivet head 5. The wedge block 31 first cooperates with the wedge connecting block 32, and pushes the wedge connecting block 32 to drive the third connecting rod 48 to drive the first connecting rod 45 and the second connecting rod 47 to push the intermediate slide table 41 along the guide rail 42 towards the tooling fixed block 211, so that the tooling fixed block 211 and the tooling moving block 212 are closed, and the pad block 24 clamps the workpiece and the rivet.

[0052] S4: The wedge block 31 continues to move down, as shown in step 3. At this time, the wedge block 31 is parallel to the wedge connecting block 32. The wedge connecting block 32 is stationary and does not drive the third connecting rod 48 to change its position until the rivet head 5 presses down the rivet post to perform riveting.

[0053] S5: After the riveting is completed, the rivet head 5 is raised, the wedge block 31 leaves the wedge connecting block 32, the tension spring 35 rebounds and causes the wedge connecting block 32 to drive the third connecting rod 48 to drive the first connecting rod 45 and the second connecting rod 47 to reset the intermediate slide table 41, and the tooling fixed block 211 and the tooling moving block 212 separate.

[0054] Preferably, the positioning module 2 is located on one side of the top of the fixture base 1. The top side of the positioning module 2 is connected to the platform surface at the top of the fixture base 1 by bolts. The positioning module includes: a clamping block 21, a tooling fixed block 211, a tooling moving block 212, a rivet hole 22, and a workpiece placement groove 23. The clamping block 21 is located on one side of the fixture base 1. The clamping block 21 is connected to the platform surface at the top of the fixture base 1 by bolts. A rivet hole 22 is opened in the center of the top of the clamping block 21. Workpiece placement grooves 23 are opened through the front and rear sides of the clamping block 21. Pads 24 are attached to the left and right side walls of the workpiece placement groove 23. The thickness of the pads 24 can be adjusted according to the specifications of the door lock connecting rod to be fixed. The pads 24 can be attached to the left and right side walls of the workpiece placement groove 23 by pasting or bolting. The clamping block 21 is divided into a tooling fixed block 211 and a tooling moving block 212 along the central axis. The side connected to the fixture base 1 is the tooling fixed block 211.

[0055] Preferably, the drive module 3 is bolted to the side of the mounting groove 11 away from the positioning module 2. The drive module 3 includes: a wedge block 31, a wedge connecting block 32, a spring fixing block 34, and a tension spring 35. One side of the wedge block 31 is in close contact with the inner wall of the mounting groove 11 away from the clamping block 21. The other side of the wedge block 31 is provided with a wedge connecting block 32. A threaded hole is opened in the center of the side of the wedge connecting block 32 away from the wedge block 31. A discharge bolt 33 is provided in the threaded hole through threaded engagement. A spring fixing block 34 is sleeved on the side of the discharge bolt 33 near the screw head. The bottom of the spring fixing block 34 is bolted to the bottom of the mounting groove 11. A tension spring 35 is sleeved in the center of the discharge bolt 33. One side of the tension spring 35 abuts against the wedge connecting block 32 and the other side abuts against the spring fixing block 34. A connecting rod 36 is integrally provided on the top of the wedge block 31. The top of the connecting rod 36 is fixedly mounted on the main shaft of the riveting machine.

[0056] It should be specifically noted that the wedge block 31 is fixed on the main shaft of the lifting structure of the riveting machine. If the main shaft of the riveting machine is rotating, it is fixed on the outside of the rotating shaft to the guide shaft that moves up and down without rotating. When the rivet head 5 descends, the wedge block first engages with the inclined surface of the connecting block, pushing the connecting rod locking module 4 to clamp the workpiece and the rivet post. The rivet head 5 continues to move down to contact the rivet post and perform riveting. At this time, the wedge block 31 will move down synchronously and be parallel to the side of the wedge connecting block 32. The back of the wedge block 31 is in close contact with the inner wall of the mounting groove 11 to better ensure the clamping force.

[0057] Preferably, one side of the connecting rod locking module 4 is connected to the drive module 3 by bolts, and the other side of the connecting rod locking module 4 is connected to the positioning module 2 by bolts. The connecting rod locking module 4 includes: a middle slide 41, a guide rail 42, a first connecting rod seat 44, a second connecting rod seat 46, and a third connecting rod 48. The middle slide 41 is bolted to the bottom of the tooling moving block 212 on the side away from the tooling fixed block 211. A guide rail groove is opened at the bottom of the mounting groove 11, and the guide rail groove is located on the front and rear sides of the middle slide 41. A guide rail 42 is bolted into the guide rail groove, and a slider 43 is sleeved on the top of the guide rail 42. The top of the slider 43 is bolted to the middle slide 41. A bolt is bolted to the side wall of the mounting groove 11 on the side away from the clamping block 21. Connecting rod seat 44 is installed on both the front and rear sides of wedge block 31. Connecting rod 45 is secured in the center of connecting rod seat 44 via connecting shaft 1. Connecting rod seat 46 is installed on both the front and rear sides of the side wall of the intermediate slide 41 away from tooling block 211 via bolts. Connecting rod 47 is secured in the center of connecting rod seat 46 via connecting shaft 2. Connecting rod 47 is secured in the center of the side of connecting rod 45 away from connecting rod seat 44 via connecting shaft 3. Connecting rod 48 is fitted on one side of connecting rod 45 away from connecting rod seat 44 via connecting shaft 3. Connecting rod 48 is fitted on the outer side of connecting rod 45 away from connecting rod seat 44 via connecting shaft 3. Connecting rod 48 is fitted on the side of wedge connecting block 32 away from wedge block 31 via connecting shaft 4.

[0058] It should be specifically noted that when the riveting machine is not started, there is an angle between the first connecting rod 45 and the second connecting rod 47. As the riveting machine starts, the connecting rod locking module 4 drives the third connecting rod 48 to move, which will increase the angle between the first connecting rod 45 and the second connecting rod 47, thus pushing the intermediate slide 41 to move.

[0059] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
