Description

Technical Field

[0001] The utility model relates to the technical field of laser welding support devices, in particular to a sliding support mechanism for a laser welding tooling. Background Technique

[0002] Laser welding is a welding method that uses a focused laser beam as an energy source to bombard the heat generated by the welded part. Due to the optical properties of the laser such as refraction and focusing, laser welding is very suitable for welding of micro parts and parts with very poor accessibility.

[0003] Due to high energy and fast speed in laser welding, the parts are heated during welding and will produce a certain amount of deformation. The existing lower tooling for welding the motorcycle K1 sub-assembly has no shell positioning support. After welding, the shell will produce a downward deformation amount, and the deformation amount ≥ 0.5 mm, resulting in poor dimensions and increasing the scrap rate of the motorcycle K1 sub-assembly. Content of the Utility Model

[0004] To solve the problem of the easy generation of downward deformation of the laser-welded shell proposed in the above background technique, the utility model provides the following technical solutions:

[0005] A sliding support mechanism for a laser welding tooling, including a support seat for cooperating with a copy support member two to limit the shell b and a support block for cooperating with a copy support member one to limit the shell a;

[0006] An outer wall of the support seat is provided with a sliding seat for supporting and limiting the support block.

[0007] A lower end of the sliding seat is provided with a sliding disk for guiding the support block, and the sliding disk rotates to control the movement of the support block.

[0008] A middle part of the sliding disk is provided with a plurality of inclined slots for guiding the support block.

[0009] Further, a core shaft for limiting the shell b is installed in a middle part of an upper end of the support seat.

[0010] Further, an adjusting gasket for supporting the sliding seat is installed at a lower end of the sliding seat. A plurality of through holes are provided in a middle part of the adjusting gasket. A bolt one is installed in a middle part of the sliding seat, and the bolt one passes through the through hole and is fixed to an outside of the support seat.

[0011] Further, a baffle is installed on an outer wall of the adjusting gasket. A limiting hole is provided in a middle part of the baffle. A bolt two is installed in a middle part of the baffle, and the bolt two passes through the limiting hole and is fixed to a bottom of the sliding seat.

[0012] Furthermore, the sliding seat includes a fixed disk, and a support disk for supporting the support block is installed at the upper end of the fixed disk. A plurality of sliding grooves for limiting the support block are formed in the middle of the support disk, and a limiting groove is formed at the lower end of the cavity of the sliding groove.

[0013] Furthermore, the support block includes a fixed block for supporting the housing a. A slider that slides in the cavity of the sliding groove is installed at the lower end of the fixed block. A limiting block that slides in the cavity of the limiting groove is installed at the lower end of the slider. A sliding rod is installed at the bottom of the limiting block.

[0014] Furthermore, a handle for rotating the sliding disk is installed on the outer wall of the sliding disk, and a screw rod for cooperating with the sliding disk to limit the handle is installed at one end of the handle.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] When welding the housing a and the housing b, the housing b is placed on the upper end of the support seat and is preliminarily limited by the core shaft. Then, the housing a is placed on the upper end of the housing b. By moving the copy support member one and the copy support member two downward, the copy support member two presses the housing b tightly, and the copy support member one presses one end of the housing a. By rotating the sliding disk with the hand-held handle, the sliding rod slides in the cavity of the inclined groove. Through the limitation of the sliding block by the sliding groove, the sliding rod moves from the position close to the inner wall of the sliding disk in the inclined groove to the position close to the outer wall of the sliding disk in the inclined groove, thereby synchronously driving a plurality of fixed blocks to contract and move to the bottom of the housing a to support the housing a and avoid downward deformation of the housing a during welding.

[0029] A sliding seat 300 for supporting and limiting the support block 400 is installed on the outer wall of the support base 50. A mandrel 60 for limiting the housing b 20 is installed in the middle of the upper end of the support base 50. An adjusting gasket 100 for supporting the sliding seat 300 is installed at the lower end of the sliding seat 300. A stepped groove is machined on the outer wall of the support base 50. Both the adjusting gasket 100 and the sliding seat 300 are located on the stepped groove machined on the outer wall of the support base 50, and the adjusting gasket 100 is at the lower end and the sliding seat 300 is at the upper end. A plurality of threaded holes are machined on the stepped groove of the adjusting gasket 100.

[0030] A plurality of through holes 110 are opened in the middle of the adjusting gasket 100, and the through holes 110 are aligned with the threaded holes on the stepped groove. A first bolt 70 is installed in the middle of the sliding seat 300, and the first bolt 70 passes through the through hole 110 and is fixed to the outside of the support base 50. The first bolt 70 passes through the upper end cavity of the sliding seat 300, and after passing through the through hole 110, it is screwed into the threaded hole at the upper end of the stepped groove, thereby fixing the sliding seat 300 and the adjusting gasket 100 on the step of the support base 50.

[0031] A sliding plate 500 for guiding the support block 400 is installed at the lower end of the sliding seat 300. A baffle 200 is sleeved on the outer wall of the adjusting gasket 100. A plurality of limiting holes 210 are formed in the middle of the baffle 200. A second bolt 80 is installed in the cavity of the limiting hole 210, and the second bolt 80 passes through the limiting hole 210 and is fixed to the bottom of the sliding seat 300. Threaded holes are synchronously machined at the bottom of the sliding seat 300 to facilitate fixing the baffle 200 to the bottom of the sliding seat 300 in cooperation with the second bolt 80, and the baffle 200 is used to support the sliding plate 500.

[0032] When the sliding plate 500 rotates, it controls the support block 400 to expand or contract at the upper end of the sliding seat 300. When expanding, it is convenient to place the housing a10. When contracting, it is convenient to provide stable support for the housing a10.

[0033] The sliding seat 300 includes a fixed plate 310, and the fixed plate 310 is located at the upper end of the adjusting gasket 100. The first bolt 70 fixes the fixed plate 310 through the threaded hole in the external step groove of the support seat 50.

[0034] A support plate 320 for supporting the support block 400 is fixedly installed at the upper end of the fixed plate 310.

When installing the handle 510, the screw rod 511 is screwed into the threaded hole on the outer wall of the sliding plate 500. A plurality of inclined grooves 520 for guiding the support block 400 are formed in the middle of the sliding plate 500, and the sliding rod 413 slides in the cavity of the inclined groove 520. One end of the cavity of the inclined groove 520 is close to the outer wall of the sliding plate 500, and the other end of the cavity of the inclined groove 520 is close to the inner wall of the sliding plate 500.

[0038] When welding the housing a10 and the housing b20, the housing b20 is placed on the upper end of the support base 50 and is preliminarily limited by the mandrel 60. Then, the housing a10 is placed on the upper end of the housing b20. By moving the copy support member one 30 and the copy support member two 40 downward, the copy support member two 40 presses the housing b20, and the copy support member one 30 presses one end of the housing a10. By rotating the sliding disk 500 by hand through the handle 510, the sliding rod 413 slides in the cavity of the inclined groove 520. Through the limit of the slider 411 by the sliding groove 321, the sliding rod 413 moves from the position close to the inner wall of the sliding disk 500 in the inclined groove 520 to the position close to the outer wall of the sliding disk 500 in the inclined groove 520, thereby synchronously driving the contraction of a plurality of fixing blocks 410 and moving them to the bottom of the housing a10 to support the housing a10 and avoid downward deformation of the housing a10 during welding.
