Technical Field

[0001] This utility model belongs to the field of fixture technology, and in particular relates to a piston tooling fixture. Background Technology

[0002] A piston is a reciprocating component in the cylinder block of a car engine. The basic structure of a piston can be divided into the top, head, and skirt. The piston top is the main part that makes up the combustion chamber, and its shape depends on the type of combustion chamber used. Gasoline engines mostly use flat-top pistons, which have the advantage of a small heat absorption area. Diesel engine piston tops often have various recesses, the specific shape, position, and size of which must be adapted to the requirements of mixture formation and combustion in the diesel engine.

[0003] However, during piston machining, the piston skirt is usually an irregularly shaped structure, which is very unfavorable for clamping and machining. Therefore, we have specially designed a piston tooling fixture. Utility Model Content

The first right-angle frame is provided with a connecting tooth fork parallel to the second right-angle frame, and the second right-angle frame is provided with a locking tooth fork parallel to the first right-angle frame. A clamping area is formed between the connecting tooth fork and the locking tooth fork. The locking bolt and locking element are located at the end of the locking tooth fork and abut against the outside of the connecting tooth fork; A positioning element is provided on the second right-angle bracket and extends toward the connecting tooth fork; The connecting tooth fork is provided with a clamping protrusion, and the clamping protrusion is provided with an arc-shaped engagement surface.

[0006] In the above technical solution, the positioning element further includes: The positioning rod is mounted on the second right-angle bracket. Spring sheet, the spring is arc-shaped, and multiple spring sheets are arranged in a circumferential array to form a spindle-shaped structure; The ends of the spring plates at both ends of the spindle-shaped structure are connected to fixing pads.

[0007] Furthermore, in the above technical solution, an arc-shaped segment is provided on the connecting tooth fork.

[0008] In the above technical solution, the clamping protrusions are further arranged alternately between the left and right sides of the connecting tooth fork frame.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0016] Example 1: This embodiment provides a piston tooling fixture, including: The clamping frame 1 includes a first right-angle frame 11 and a second right-angle frame 12.

A clamping area is formed between the connecting tooth fork 111 and the locking tooth fork 121. Locking bolt 2, the locking element is located at the end of locking tooth fork 121 and abuts against the outside of connecting tooth fork 111; Positioning element 3 is disposed on the second right-angle bracket 12 and extends toward the connecting tooth fork 111; The connecting tooth fork 111 is provided with a clamping protrusion 1111, and the clamping protrusion 1111 is provided with an arc-shaped hugging surface 11111.

[0017] As can be seen from this embodiment, a piston 10 tooling fixture includes a clamping frame 1, a locking bolt 2, and a positioning element 3; The clamping frame 1 is right-angled and includes a first right-angle frame 11 and a second right-angle frame 12. A connecting tooth fork 111 is provided on the first right-angle frame 11, and a locking tooth fork 121 is provided on the second right-angle frame 12. The connecting tooth fork 111 and the second right-angle frame 12 are arranged parallel to each other, and the locking tooth fork 121 is arranged parallel to the first right-angle frame 11. The connecting tooth fork 111 and the locking tooth fork 121 are arranged facing each other and form a rectangular structure. Furthermore, the connecting tooth fork 111 is made of elastic steel and has a certain degree of elasticity. The connecting tooth fork 111, the locking tooth fork 121, the first right-angle bracket 11, and the second right-angle bracket 12 are integrally welded together by universal welding rods. Furthermore, the connecting toothed fork 111 is provided with a clamping protrusion 1111, and the clamping protrusion 1111 is also provided with an arc-shaped engagement surface 11111. The piston 10 is positioned as follows: Figure 1 As shown, the piston 10 is placed parallel to the connecting tooth fork 111 and is clamped and fixed by the clamping protrusion 1111. The arc-shaped clamping surface 11111 helps to improve the clamping and fixing effect.

[0018] Furthermore, the opening of the locking tooth fork 121 is larger than the opening size of the connecting tooth fork 111 and extends to the outside of the connecting tooth fork 111. A locking bolt 2 is connected to the locking tooth fork 121. The locking bolt 2 is threadedly engaged with the locking tooth fork 121 and continuously moves closer to or further away from the connecting tooth fork 111 during use. During the process of moving closer to or further away, the connecting tooth fork 111 is controlled to clamp or release the piston 10, thereby achieving the effect of clamping the piston 10. The positioning element 3 is installed on the second right-angle bracket 12 and extends to the connecting tooth fork 111. When in use, the positioning element 3 will connect with the connecting end of the piston 10 to position the piston 10 and control the piston 10 to be in a position relative to the center of the connecting tooth fork 111, which is convenient for subsequent processing. The connection method is simple and can firmly clamp the piston 10. At the same time, it can avoid the inconvenience of clamping caused by the irregular structure of the piston 10 connection end. Furthermore, it can use the positioning end in conjunction with the piston 10 connection end to clamp and position the piston 10, thereby improving the clamping effect.

The positioning rod 31 extends outward through the fixed tooth fork. Multiple arc-shaped spring plates 32 are arranged in a spindle-shaped circumferential array, and the two ends of the spindle-shaped structure composed of multiple spring plates 32 are connected to fixing pads 33 to fix the spring plates 32. Furthermore, the fixing pad 33 is displaced along the positioning rod 31 during the elastic change of the spring sheet 32; During use, the spring plate 32 will engage with the hole on the connecting end of the piston 10 rod, and will deform elastically during the engagement process. Even so, the spring plate 32 will still press against the hole wall, thus keeping the hole in a circular position with the positioning rod 31.
