[0002] The automotive air compressor is an important component of the automobile. Its function is to generate compressed air to provide energy to the vehicle's braking system. With the development trend of people's requirements for safe, comfortable, stable and low-noise automobiles, higher standards are put forward for the working stability of the air compressor.

[0003] The cylinder head of the engine air compressor is an important component of the vehicle air compressor. Figure 7 As shown, the compressor cylinder head 18 has a circular connecting hole 21 at each of its four corners. A side hole 19 is formed on the left side of the compressor cylinder head 18, and a communication port 20 is formed at the upper portion of one side of the side hole 19. The upper portion of the compressor cylinder head 18 has an inner contour 22, which needs to be machined. Currently, there is no specialized tooling for securing the compressor cylinder head; instead, the outer edge of the upper portion of the compressor cylinder head 18 is simply clamped. This can easily cause interference between the clamping components and the machining tool when machining the inner contour 22. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a tool for processing the cylinder head of an engine air compressor, which has accurate positioning, can greatly improve the processing efficiency, and can effectively avoid mutual interference when processing the inner contour.

[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide a tool for processing the cylinder head of an engine air compressor, including a tool base plate, wherein the left and right lifting seats that can be lifted up and down are respectively installed on both sides of the upper end of the tool base plate, and a driving oil cylinder is vertically installed on the lower end of the tool base plate, and the piston rod of the driving oil cylinder passes through the tool base plate and is connected to the corresponding left lifting seat or the right lifting seat. The inner side of the left lifting seat and the inner side of the right lifting seat are both equipped with at least one inclined sliding side push block, and the lower end of the side push block is also horizontally slidably connected to the tool base plate, and four support columns arranged in a rectangular shape are installed on the upper end of the tool base plate, and the upper end of the support column is provided with a hole protrusion, and a notch is opened in the middle of the lower end of the left lifting seat. The upper end of the tool base plate is located on the left side of the left lifting seat and is equipped with a hole rod for horizontal sliding. One end of the hole rod passes through the notch.

[0006] As a supplement to the technical solution described in the present invention, the inner sides of the left lifting seat and the right lifting seat are both inclined surfaces, and the distance between the two inclined surfaces gradually decreases from bottom to top. The side of the side push block is provided with a guide protrusion, and an inclined track is obliquely provided on the inclined surface.

[0007] As a supplement to the technical solution described in the present invention, guide holes are vertically opened on the front and rear sides of the upper end of the left lifting seat and the front and rear sides of the upper end of the right lifting seat, and guide columns are installed on the upper end of the tooling base plate and inserted into the guide holes.

[0008] As a supplement to the technical solution of the present invention, an adjusting bolt is screwed onto the upper end of the left lifting seat, and the lower end of the adjusting bolt extends into the notch.

[0009] As a supplement to the technical solution described in the utility model, a straight through hole is provided at the upper end of the tooling base plate below each side push block, and a limiting bolt is inserted into the straight through hole from bottom to top, and the upper end of the limiting bolt is screwed and fixed to the side push block.

[0010] As a supplement to the technical solution of the present invention, one end of the hole rod is provided with a simulated portion.

[0011] Beneficial Effects: The present invention relates to a tooling for machining an engine air compressor cylinder head. Two drive cylinders control the left and right lifters to move downward together, causing the side pusher on the right side of the left lifter and the side pusher on the left side of the right lifter to move relatively close to each other, clamping the two sides of the air compressor cylinder head. Simultaneously, the left lifter moves downward to press the hole rod, causing one end of the hole rod and the shaped portion to also press the air compressor cylinder head, thereby achieving compression of the air compressor cylinder head. This compression structure avoids interference between the compression component and the machining tool when machining the inner contour. The present invention also has the advantages of simple structure, ease of use, and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalents also fall within the scope of the claims appended hereto.

[0021] The embodiment of the present utility model relates to a tool for processing the cylinder head of an engine air compressor, such as Figure 1-7 As shown, it includes a tooling base plate 1, and the left and right lifting seats 2 and 3 that can be lifted up and down are respectively installed on both sides of the upper end of the tooling base plate 1. The lower end of the tooling base plate 1 is located below the left and right lifting seats 2 and 3, and a driving cylinder 5 is vertically installed. The piston rod of the driving cylinder 5 passes through the tooling base plate 1 and is connected to the corresponding left and right lifting seats 2 or 3. The inner side of the left and right lifting seats 2 and 3 are both installed with at least one inclined sliding side push block 4, and the lower end of the side push block 4 is also connected to the tooling base plate 1 for horizontal sliding. The upper end of the tooling base plate 1 is installed with four support columns 10 arranged in a rectangular shape, and the upper end of the support column 10 is provided with a hole protrusion 11. The middle part of the lower end of the left lifting seat 2 is provided with a notch 12. The upper end of the tooling base plate 1 is located on the left side of the left lifting seat 2 and is provided with a horizontally sliding hole rod 6. One end of the hole rod 6 passes through the notch 12 and is provided with a simulated portion 23.

[0022] As a driving description of the side push block 4, the inner sides of the left lifting seat 2 and the right lifting seat 3 are both inclined surfaces 13, and the distance between the two inclined surfaces 13 gradually decreases from bottom to top. The side of the side push block 4 is provided with a guide protrusion 16, and the inclined surface 13 is inclinedly provided with an inclined track 15; the inclined track 15 cooperates with the guide protrusion 16 to realize the inclined sliding connection between the left lifting seat 2 and the side push block 4.

[0023] As a guide for the left lifting seat 2 and the right lifting seat 3, guide holes 14 are vertically opened on the front and rear sides of the upper end of the left lifting seat 2 and the front and rear sides of the upper end of the right lifting seat 3, and the upper end of the tooling base 1 is installed with a guide column 8 inserted into the guide hole 14; the guide column 8 cooperates with the guide hole 14 to ensure the stability of the up and down movement of the left lifting seat 2 and the right lifting seat 3.

[0024] As a preferred solution for the left lifting seat 2, an adjusting bolt 7 is screwed onto the upper end of the left lifting seat 2, and the lower end of the adjusting bolt 7 extends into the notch 12; when the left lifting seat 2 moves downward, the hole rod 6 is pressed by the lower end of the adjusting bolt 7, and the adjusting bolt 7 can be adjusted up and down in height, which is more widely applicable.

[0025] The upper end of the tooling base plate 1 is located below each side push block 4 and is provided with a flat through hole 17. A limiting bolt is inserted into the flat through hole 17 from bottom to top, and the upper end of the limiting bolt is screwed and fixed to the side push block 4; through the cooperation between the flat through hole 17 and the limiting bolt, the side push block 4 can only slide back and forth horizontally within a certain range.

[0026] Reference Figure 1 and Figure 7 As shown, first, the air compressor cylinder head 18 is placed in reverse on the four support columns 10, and the hole protrusions 11 at the upper ends of the support columns 10 are inserted into the corresponding connecting through holes 21 to realize the position limit of the air compressor cylinder head 18, move the hole rod 6, one end of the hole rod 6 is inserted into the side hole 19, and the shaped part 23 at the end of the hole rod 6 is inserted into the connecting port 2, and the two driving cylinders 5 are started. The two driving cylinders 5 respectively control the left lifting seat 2 and the right lifting seat 3 to move downward together, so that the side push block 4 on the right side of the left lifting seat 2 and the side push block 4 on the left side of the right lifting seat 3 move relatively close to each other to clamp the two sides of the air compressor cylinder head 18. At the same time, the left lifting seat 2 moves downward to press the hole rod 6, so that one end of the hole rod 6 and the shaped part 23 also press the air compressor cylinder head 18, so that the air compressor cylinder head 18 is tightened, and then the machining center processes the inner contour 22 of the air compressor cylinder head 18.

[0027] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0029] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0030] The above is a detailed introduction to the tooling for processing the cylinder head of an engine air compressor provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
