Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a machining fixture for the front and back sides of an automotive air compressor cylinder head, which enables dual-station machining, greatly improving machining efficiency and providing precise positioning.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A tooling for machining the front and back sides of an automotive air compressor cylinder head is provided, including a tooling base plate. A front work station and a back work station are respectively provided on both sides of the upper end of the tooling base plate. The front work station includes a right fixed block, a left movable block, and two symmetrically arranged L-shaped blocks. The left movable block and the right fixed block are respectively installed behind the two L-shaped blocks on the upper end of the tooling base plate. Limiting notches are provided on the inner sides of both the left movable block and the right fixed block. A driving block is installed on the upper end of the tooling base plate behind the left movable block on the left. The system includes a drive cylinder that controls the up-and-down movement of the drive block. The drive block has an inclined guide groove on the side near the left movable block. The left rear side of the left movable block has a guide part that cooperates with the inclined guide groove. The reverse workstation includes five vertically arranged pillars, three of which have a hole protrusion at their upper ends. The upper end of the tooling base plate is equipped with a pressing device on both sides of the front workstation and on the right side of the reverse workstation. The upper end of the tooling base plate is equipped with a rear pressing device at the rear of the front workstation. The upper end of the tooling base plate is equipped with a double-fork locking device at the middle of the reverse workstation.

[0006] As a supplement to the technical solution described in this utility model, the upper end of the tooling base plate is provided with a support block located outside the drive block. The end face of the support block near the left movable block is a vertical surface, and the end of the left movable block slides up and down along the vertical surface.

[0007] As a supplement to the technical solution described in this utility model, the pressing device includes a pressure plate and a pressing cylinder vertically mounted on the upper end of the tooling base plate. The upper end of the piston rod of the pressing cylinder is equipped with a horizontally arranged pressure plate.

[0008] As a supplement to the technical solution described in this utility model, the rear pressing device includes a second pressing plate and a rear pressing cylinder. The rear pressing cylinder is vertically installed at the bottom of the tooling base plate. The piston rod of the rear pressing cylinder passes through the tooling base plate and is connected to the middle of the second pressing plate.

[0010] Beneficial effects: This utility model relates to a machining fixture for the front and back sides of an automotive air compressor cylinder head. The front station uses two L-shaped blocks and a limiting notch on the inner side of the right fixed block to limit the three corners of the air compressor cylinder head. The drive cylinder is activated, and the drive cylinder controls the drive block to move downward. The drive block pushes the left movable block closer to the air compressor cylinder head until the limiting notch on the inner side of the left movable block engages with the remaining corner of the air compressor cylinder head, achieving precise positioning of the air compressor cylinder head in the front. This positioning reduces interference during machining. Then, the pressing device and the rear pressing device are activated to press the air compressor cylinder head. The CNC machine tool performs precision machining on the holes, the upper port of the circular channel, and part of the contour on the front side of the air compressor cylinder head. The reverse workstation first places the air compressor cylinder head upside down onto five support pillars. The protruding holes on the upper ends of three of the support pillars interlock with the corresponding three holes, achieving precise positioning of the air compressor cylinder head in reverse. The lowering device and double-fork locking device are then activated to secure the air compressor cylinder head. A CNC machine tool then performs precision machining on the oblique channels, shallow grooves, and some recessed areas on the reverse side of the air compressor cylinder head. This utility model features dual-station processing in both forward and reverse directions, significantly improving processing efficiency and ensuring precise positioning.

[0013] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0014] The present invention relates to a tooling for machining the front and back sides of an automotive air compressor cylinder head, such as... Figure 1-7As shown, the fixture includes a base plate 1. A front workstation and a back workstation are respectively provided on both sides of the upper end of the base plate 1. The front workstation includes a right fixed block 3, a left movable block 4, and two symmetrically arranged L-shaped blocks 2. The left movable block 4 and the right fixed block 3 are respectively installed behind the two L-shaped blocks 2 at the upper end of the base plate 1. Limiting notches 15 are provided on the inner sides of both the left movable block 4 and the right fixed block 3. A drive block 10 and a drive cylinder 12 for controlling the up-and-down movement of the drive block 10 are installed at the left rear of the left movable block 4 at the upper end of the base plate 1. The drive block 10 has an inclined guide groove 13 on one side near the left movable block 4. The left rear side of the left movable block 4 has a guide part 14 that cooperates with the inclined guide groove 13. The reverse station includes five vertically arranged pillars 5, three of which have a hole protrusion 6 at their upper ends. The upper end of the tooling base plate 1 is equipped with a pressing device 8 on both sides of the front station and on the right side of the reverse station. The upper end of the tooling base plate 1 is equipped with a rear pressing device 9 at the rear of the front station. The upper end of the tooling base plate 1 is equipped with a double fork locking device 7 at the middle of the reverse station.

[0015] Reference Figure 2 As shown, to illustrate the front workstation, the upper surface of the fixture base plate 1, the right fixed block 3, the left movable block 4, and the two L-shaped blocks 2 form a placement space. First, the air compressor cylinder head 31 is placed upright in the placement space. The two L-shaped blocks 2 and the limiting notches 15 on the inner side of the right fixed block 3 limit the three corners of the air compressor cylinder head 31. The drive block 10 and the left movable block 4 are connected by an inclined sliding connection. The left movable block 4 is placed on the fixture base plate 1. The limiting notches 15 on the inner side of the left movable block 4 do not align with the remaining corner of the air compressor cylinder head 31. At this point, the drive cylinder 12 needs to be activated. The drive cylinder 12 controls the drive block 10 to move downward. The drive block 10 will push the left movable block 4 closer to the air compressor cylinder head 31 until the limiting notch 15 on the inner side of the left movable block 4 is engaged with the remaining corner of the air compressor cylinder head 31, achieving precise positioning of the air compressor cylinder head 31 in the positive direction. Then, the pressing device 8 and the rear pressing device 9 are activated to press the air compressor cylinder head 31 tightly. The CNC machine tool performs precision machining on the hole 33, the upper port of the circular channel 32, and part of the contour on the front of the air compressor cylinder head 31.

[0016] As an explanation of the reverse work station, the air compressor cylinder head 31 is first placed in reverse on the five support pillars 5. The hole protrusions 6 at the upper end of three of the support pillars 5 are interlocked with the corresponding three holes 33 to achieve precise positioning of the air compressor cylinder head 31 in reverse. The pressing device 8 and the double fork locking device 7 are activated to fix the air compressor cylinder head 31. The CNC machine tool performs precision machining on the inclined channel 34, the long shallow groove 35 and some recesses on the reverse side of the air compressor cylinder head 31.

[0017] The tooling base plate 1 has a support block 11 located on the outer side of the drive block 10. The end face of the support block 11 near the left movable block 4 is a vertical surface 18. The end of the left movable block 4 slides up and down along the vertical surface 18.

[0018] The pressing device 8 includes a pressing plate 17 and a pressing cylinder 16 vertically mounted on the upper end of the tooling base plate 1. The upper end of the piston rod of the pressing cylinder 16 is equipped with a horizontally arranged pressing plate 17. When pressing is required, the pressing cylinder 16 controls the pressing plate 17 to move downward so that one end of the pressing plate 1 presses against the edge of the air compressor cylinder head 31, avoiding the processing area.

[0019] The rear pressure device 9 includes a second pressure plate 19 and a rear pressure cylinder 20. The rear pressure cylinder 20 is vertically installed at the bottom of the tooling base plate 1. The piston rod of the rear pressure cylinder 20 passes through the tooling base plate 1 and is connected to the middle of the second pressure plate 19. One end of the second pressure plate 19 has a U-shaped opening 24, and the other end of the second pressure plate 19 has a through hole 22. A screw 21 is vertically inserted into the through hole 22. The lower end of the screw 21 is fixed to the tooling base plate 1. A limit nut 23 is screwed onto the screw 21 below the second pressure plate 19. When tightening is required, the rear pressure cylinder 20 is activated. The piston rod of the rear pressure cylinder 20 retracts to control the second pressure plate 19 to move downward, so that the second pressure plate 19 presses down on the upper end of the air compressor cylinder head 31, thereby tightening the air compressor cylinder head 31. When the pressure plate 19 moves downward, it stops moving after hitting the limit nut 23. The downward position of the pressure plate 19 can be adjusted within a certain range by rotating the limit nut 23.

[0020] The double-fork locking device 7 includes a rotating base 25 and two clamping arms 26 arranged in a cross configuration. The rotating base 25 is fixedly mounted on the tooling base plate 1. The rotating base 25 is rotatably connected to the middle of the two clamping arms 26 via a rotating shaft 30. Each clamping arm 26 has a hook portion 27 on the outer side of its upper end. A locking cylinder 28 is vertically mounted at the bottom of the tooling base plate 1 below the rotating base 25. A connecting plate 29 is rotatably connected to each side of the upper end of the piston rod of the locking cylinder 28. The upper ends of the two connecting plates 29 are respectively connected to... The lower ends of the two clamping arms 26 are rotatably connected; when the double fork locking device 7 is not locked, the hooks 27 at the upper ends of the two clamping arms 26 are close to each other, so that the hooks 27 can pass through the lower port of the circular channel 32. When locking is required, the locking cylinder 28 is activated. The piston rod of the locking cylinder 28 extends and controls the lower ends of the two clamping arms 26 to unfold through the two connecting plates 29, so that the hooks 27 at the upper ends of the two clamping arms 26 also unfold, so that the hooks 27 hook onto both sides of the lower port of the circular channel 32, thereby achieving locking and positioning at the circular channel 32.

[0021] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0022] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
