Description

Technical Field

[0001] This utility model relates to the field of linear friction welding technology, specifically to a clamping and positioning device for linear friction welding of chain link products. Background Technology

[0002] Currently, high-end chain links abroad are manufactured using linear friction welding. In order to ensure the dimensions of the chain links after welding, it is necessary to ensure that the welding positions of each chain link half ring are aligned before welding. The common method is to clamp the chain link half rings on both sides separately. Since the positioning surface of the chain link is an arc surface and there is a gap between the straight side and the fixture, it is easy to cause inaccurate clamping and positioning, resulting in tilting. Multiple adjustments are required to complete the clamping of the specimen.

[0003] Therefore, the inventors provide a clamping and positioning device for linear friction of chain link products. Utility Model Content

[0004] (1) Technical problems to be solved This utility model provides a clamping and positioning device for linear friction of chain link products, which solves the technical problems of low clamping and positioning accuracy and efficiency of linear friction of chain link products.

The fixed base is installed on the side end face of the chain link clamp and has a positioning hole. The positioning block includes a first part and a second part connected to each other. The angle between the first part and the second part is 90°. One end of the first part is slidably inserted into the positioning hole. The second part is parallel to the end face of the chain link clamp and is used to push the chain link half ring so that the welding surface of the chain link half ring is parallel to the end face of the chain link clamp.

[0006] Furthermore, the inner wall of the positioning hole is provided with grooves on both opposite sides along its depth direction, and the first part is provided with a protrusion along its length direction that cooperates with the groove.

[0007] Furthermore, the groove is wedge-shaped.

[0008] Furthermore, the protrusion is detachably connected to the first part.

[0009] Furthermore, the length of the protrusion is greater than the depth of the positioning hole.

[0010] Furthermore, the second part has a magnetic attraction part on the end face facing the chain link clamp for attracting the chain link half ring.

[0011] Furthermore, the first part and the second part are integrally formed structures.

[0012] Furthermore, both the first and second parts are rod-shaped structures with rectangular cross-sections.

[0013] (3) Beneficial effects In summary, this utility model achieves rapid and accurate positioning and clamping of the chain link half-ring before welding by installing the fixing seat on the chain link clamp and moving the positioning block back and forth along the positioning hole on the fixing seat in a straight line to ensure that the welding surface of the chain link half-ring is parallel to the end face of the chain link clamp.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] This utility model embodiment provides a clamping and positioning device for linear friction of chain link products, see [link to related documentation]. Figures 1-4 The device may include a fixed base 1 and a positioning block 2. The fixed base 1 is mounted on the side end face of the chain link clamp 100 and has a positioning hole 101. The positioning block 2 includes a first part 201 and a second part 202 connected to each other. The angle between the first part 201 and the second part 202 is 90°. One end of the first part 201 is slidably inserted into the positioning hole 101. The second part 202 is parallel to the end face of the chain link clamp 100 and is used to push the chain link half ring 200 so that the welding surface of the chain link half ring 200 is parallel to the end face of the chain link clamp 100.

[0022] In the above embodiment, the fixing seat 2 is installed on the chain link clamp 100. The positioning block 2 moves back and forth along the positioning hole 101 on the fixing seat 1 to ensure that the welding surface of one of the chain link half rings 200 is parallel to the end face of the chain link clamp 100. The other chain link half ring 200 is clamped and positioned in the same way, thereby realizing the rapid and accurate positioning and clamping of the chain link half ring 200 before welding. The welding surfaces of the two chain link half rings 200 to be welded are quickly aligned, reducing assembly time, improving clamping efficiency, and providing a guarantee for the subsequent mass production of chain links.

[0023] As an optional implementation method, such as Figure 2 As shown, the inner wall of the positioning hole 101 is provided with grooves 1011 on both opposite sides along the depth direction of the hole, such as... Figure 3As shown, the first part 201 has a protrusion 203 along its length that mates with a sliding groove. The engagement of the sliding groove 1011 and the protrusion 203 facilitates rapid sliding of the first part 201 within the mounting hole 101 of the fixed base 1. Furthermore, the sliding groove 1011 can be wedge-shaped, ensuring reliable installation between the first part 201 and the fixed base 1 and preventing the first part 201 from derailing from the sliding groove 1011. The protrusion 203 is detachably connected to the first part 201, and the length of the protrusion 203 is greater than the depth of the positioning hole 101. The first part 201 and the second part 202 are integrally formed structures, both being rod-shaped structures with a rectangular cross-section.

[0024] As an optional implementation, the second part 202 is provided with a magnetic attraction part (not shown in the figure) on the end face facing the chain link clamp 100 for adsorbing the chain link half ring 200. The magnetic attraction part can ensure that there is no relative displacement between the second part 202 and the chain link half ring 200 during the process of pushing the chain link half ring 200.

[0025] It should be clarified that the various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to mutually.
