Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, specifically to a cylinder head machining flipping fixture. Background Technology
[0002] The cylinder head is a crucial component of an engine, typically formed by casting. Due to its complex external and internal structure, it cannot be completed in a single casting process and requires further machining after casting. Since multiple surfaces need to be machined, the cylinder head necessitates multiple flipping and clamping operations. These multiple clamping processes consume significant time, resulting in low machining efficiency. Utility Model Content
[0003] To overcome the shortcomings of the prior art, this utility model provides a cylinder head machining flipping fixture, which solves the problem of low machining efficiency of cylinder heads at present.
[0004] The technical solution adopted in this utility model is as follows: A cylinder head machining flipping fixture includes a turntable and further includes: Mounting bases, at least two, evenly distributed around the circumference of the turntable; The geared motor is mounted on one side of the mounting base; The base plate is rotatably mounted on the mounting base at one end, and connected to the geared motor at the other end. Support blocks are installed on the base plate; Positioning posts are installed on the base plate; The clamping mechanism is mounted on the base plate and located on the outside of the support block.
[0005] The top of the mounting base is provided with an air blowing pipe, and the air blowing pipe is evenly distributed with air nozzles, and the air outlet of the air nozzle is set downward.
[0006] A cover is provided above the mounting base, with one mounting base located outside the cover and the rest of the mounting bases located inside the cover.
[0007] The clamping mechanism includes a cylinder, a pressure plate mounted on the cylinder, and a connecting seat located at the front end of the cylinder. A connecting rod connects the connecting seat and the pressure plate.
[0008] The cylinder is located below the base plate, which has a through hole through which the piston rod of the cylinder passes. The through hole is provided with a sealing ring for engaging with the piston rod of the cylinder.
[0009] The side of the pressure plate that contacts the cylinder head is provided with a rubber pad.
[0010] The rubber pad has anti-slip texture.
[0011] The beneficial effects of this utility model are: The positioning pin and clamping mechanism are used to precisely fix the cylinder head to the base plate. At least two cylinder heads can be installed on the turntable at the same time. When one cylinder head is being processed, the other cylinder heads can be clamped. At the same time, the cylinder heads clamped on the base plate can be rotated by the geared motor, and different surfaces can be processed. This can effectively save the clamping time of the cylinder heads and thus improve the processing efficiency. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments: In the embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, a cylinder head machining flipping fixture includes a turntable 1, and further includes: Mounting bases 2, at least two, are evenly distributed around the circumference of turntable 1; The geared motor 3 is mounted on one side of the mounting base 2; The base plate 4 is rotatably mounted on the mounting base 2 at one end, and connected to the geared motor 3 at the other end; Support block 5 is mounted on base plate 4; Positioning post 6 is set on base plate 4; The clamping mechanism 7 is mounted on the base plate 4 and located on the outside of the support block 5.
[0019] The positioning pin 6 and the clamping mechanism 7 are used to accurately fix the cylinder head on the base plate 4. At least two cylinder heads can be installed on the turntable 1 at the same time. When one cylinder head is being processed, other cylinder heads can be clamped. At the same time, the cylinder heads clamped on the base plate 4 can be rotated by the reduction motor 3, and different surfaces can be processed. This can effectively save the clamping time of the cylinder heads and thus improve the processing efficiency.
[0020] In the embodiments, such as Figure 1 As shown, the top of the mounting base 2 is provided with an air blowing pipe 8, and air nozzles 9 are evenly distributed on the air blowing pipe 8. The air outlets of the air nozzles 9 are set downwards. After the cylinder head is processed, the metal shavings are blown off to prevent the cylinder head surface from being scratched by metal shavings when it is picked up.
[0021] In the embodiments, such as Figure 1 As shown, a cover 10 is provided above the mounting base 2. One mounting base 2 is located outside the cover 10, and the rest of the mounting base 2 are located inside the cover 10. This prevents metal chips from splashing onto other mounting bases 2 during cylinder head processing, thus affecting the processing of the next cylinder head.
[0022] In the embodiments, such as Figure 2 , Figure 3 As shown, the clamping mechanism 7 includes a cylinder 71, a pressure plate 72 mounted on the cylinder 71, and a connecting seat 73 located at the front end of the cylinder 71. A connecting rod 74 connects the connecting seat 73 and the pressure plate 72. This structure has a fast clamping speed and a large clamping force, and the cylinder head can remain stable after being clamped.
[0023] In the embodiments, such as Figure 2 , Figure 3 , Figure 4 As shown, the cylinder 71 is located below the base plate 4, and the base plate 4 has a through hole 11 through which the piston rod of the cylinder 71 passes. The through hole 11 is provided with a sealing ring 12 for engaging with the piston rod of the cylinder 71. This prevents metal shavings generated during the machining of the cylinder head from contacting the piston rod of the cylinder 71 and entering the working space of the cylinder 71, thus affecting the normal operation of the cylinder 71.
[0024] In the embodiments, such as Figure 3 , Figure 5 As shown, a rubber pad 13 is provided on the side of the pressure plate 72 that contacts the cylinder head. The rubber pad 13 has a cushioning effect, ensuring that the pressure plate 72 will not damage the surface of the cylinder head when it is pressed down.
[0025] In the embodiments, such as Figure 5 As shown, the rubber pad 13 is provided with anti-slip texture 14. After the rubber pad 13 presses against the cylinder head, the cylinder head is less likely to shift, ensuring machining accuracy.
[0026] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
