Description

Technical Field

[0001] The utility model belongs to the technical field of steel piston processing fixtures, in particular to a fixture for welding and heating steel pistons. Background Art

[0006] A support base is provided with a plurality of comb-shaped blocks, and the plurality of comb-shaped blocks are surrounded to form a motor mounting slot;

[0007] a plurality of piston pin seats fixedly connected to the plurality of comb-shaped blocks;

[0008] A top plate, which is arranged above the plurality of comb-shaped blocks and is connected to the plurality of piston pin seats via fixing bolts;

[0009] A plurality of heat-insulating columns are fixedly connected to the plurality of comb-shaped blocks, and the plurality of heat-insulating columns pass through the top plate.

[0010] As a further description of the above technical solution:

[0011] A plurality of pin rods are arranged on the comb-shaped block.

[0012] As a further description of the above technical solution:

[0013] The heat-insulating columns are made of ceramic material.

[0015] Two anti-error guide posts are provided on the support base, and the two anti-error guide posts pass through the top plate.

[0016] As a further description of the above technical solution:

[0017] A plurality of heat dissipation slots are provided on the side surface of the comb-shaped block.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In the utility model, a motor mounting groove is formed by enclosing multiple comb-shaped blocks on the support base, and the piston pin seat supports the top plate above the comb-shaped block, keeping the steel piston placed on the top plate from contacting the comb-shaped block. Multiple heat-insulating columns limit the steel piston, so that the heat of the steel piston when it is welded and heated will not be fully transferred to the motor mounting groove. While completing the rapid limiting and fixing of the steel piston, it will not cause damage to high-temperature-resistant components such as the motor in the fixture.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4 The utility model provides a technical solution: a steel piston welding heating fixture, comprising:

[0028] A support base 1 is provided with a plurality of comb-shaped blocks 2, and the plurality of comb-shaped blocks 2 are enclosed to form a motor mounting slot 3;

[0029] A plurality of piston pin seats 4, which are fixedly connected to the plurality of comb-shaped blocks 2;

[0030] A top plate 5 is provided above the plurality of comb-shaped blocks 2, and the top plate 5 is connected to the plurality of piston pin seats 4 via fixing bolts 6;

[0031] a plurality of heat-insulating columns 7, which are fixedly connected to the plurality of comb-shaped blocks 2, and the plurality of heat-insulating columns 7 pass through the top plate 5;

[0032] The comb block 2 is provided with a plurality of pins 8, which can abut against the lower end of the steel piston skirt, thereby facilitating better positioning of the steel piston;

[0033] The heat-insulating column 7 is made of ceramic material and has high heat insulation. When the steel piston is heated, it can effectively prevent heat from being transferred to the motor mounting slot 3 below through the heat-insulating column 7, thereby avoiding damage to the motor installed in the motor mounting slot 3;

[0034] Two anti-mistake guide posts 9 are provided on the support base 1. The two anti-mistake guide posts 9 pass through the top plate 5. When steel pistons of different models are placed on the fixture, the steel pistons do not match the positions of the anti-mistake guide posts 9, which will be discovered by the operator to avoid mixing.

[0035] The side of the comb-shaped block 2 is provided with a plurality of heat dissipation grooves 10. Even if heat is transferred to the comb-shaped block 2, the heat dissipation grooves 10 increase the contact area between the comb-shaped block 2 and the air, thereby facilitating rapid heat dissipation of the comb-shaped block 2 and avoiding damage to the motor installed in the motor mounting groove 3.

[0036] Working principle: First, place the steel piston on the top plate 5, and multiple heat-insulating columns 7 are pressed against the four sides of the steel piston to limit and fix the steel piston. Multiple pins 8 can press against the lower end of the steel piston skirt, thereby facilitating better positioning of the steel piston. Secondly, when the steel piston is heated, the heat-insulating columns 7 are made of ceramic material and have high heat insulation. The piston pin seat 4 supports the top plate 5 above the comb-shaped block 2, keeping the steel piston placed on the top plate 5 from contacting the comb-shaped block 2, so that the heat of the steel piston when it is welded and heated will not be fully transferred to the motor. At the mounting groove 3, when the steel piston is heated, it can effectively prevent heat from being transmitted to the motor mounting groove 3 below through the heat insulation column 7, thereby avoiding damage to the motor installed in the motor mounting groove 3. Then, even if the heat is transferred to the comb-shaped block 2, the heat dissipation groove 10 increases the contact area between the comb-shaped block 2 and the air, which is conducive to the rapid heat dissipation of the comb-shaped block 2, thereby avoiding damage to the motor installed in the motor mounting groove 3. Finally, when steel pistons of different models are placed on the fixture, if the steel piston does not match the position of the anti-mismatch guide column 9, it will be discovered by the operator to avoid mixing.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
