As the main device for regulating the temperature inside the car, the air conditioner directly affects the comfort of the vehicle. The compressor, as the core component of the automotive air conditioning system, is the main component that determines the cooling effect of the air conditioning system.

[0003] The compressor block is an important component of the automotive air conditioning compressor, such as... Figure 7 As shown, after the compressor cylinder body 27 is cast, the sprue waste 28 at the end needs to be removed. The compressor cylinder body 27 has front mounting posts 29 and rear mounting posts 30 on both the upper and lower sides. Holes 32 are provided on both sides of the front mounting posts 29 and both sides of the rear mounting posts 30. Two reinforcing ribs 31 are arranged side-by-side in the middle of the rear mounting post 30 at the bottom. The entire compressor cylinder body 27 has a relatively complex structure and is cumbersome to position. Currently, most methods involve simply fixing it and then manually knocking off the sprue waste using tools such as hammers. This not only results in an uneven sprue cross-section but also requires significant labor intensity, has high labor costs, and is inefficient. Furthermore, the compressor cylinder body 27 is prone to shaking. Summary of the Invention

[0021] 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.

[0022] The present invention relates to a cutting fixture for removing waste material from the gate of a compressor cylinder, such as... Figure 1-7As shown, the fixture includes a tooling base plate 1. A sliding plate 2 and a power cylinder 3 for driving the sliding plate 2 to slide laterally are mounted on the upper end of the tooling base plate 1. A cylinder base 4 is mounted on the sliding plate 2. A cavity 12 is opened at the upper end of the cylinder base 4. Arc-shaped support surfaces 13 are provided on both sides of the opening at the upper end of the cavity 12. A clearance groove 14 is opened on both sides of the middle part of the cavity 12. The clearance groove 14 is used to accommodate the protruding part of the middle side of the compressor cylinder 27. A downward front step 15 and a rear step 17 are respectively opened on the front and rear sides of the bottom surface of the cavity 12. An upward lifting limit protrusion 18 is provided between the middle of the rear step 17 and the bottom surface of the cavity 12. A ball-head plunger 19 is embedded in the inner wall of the cavity 12 on both sides of the rear step 17. A support 6 is installed on the rear side of the cylinder base 4. A quick clamp 7 is installed on the upper end of the support 6. A front lifting device 5 is installed on the upper end of the sliding plate 2 behind the cylinder base 4.

[0023] The quick-release clamp 7 and ball plunger 19 are existing components and can be purchased directly from the market. The quick-release clamp is a new type of manual and pneumatic clamping device that can accurately position and quickly clamp. The ball plunger, also known as a spring plunger, is a mechanical positioning element with a built-in compression spring. The preload is adjusted by the depth of the threaded insertion, and it is suitable for workpiece positioning and clamping in fixtures, molds, and automated machinery.

[0024] The tooling base plate 1 has a long through hole 8 at each of the four corners at the top. The long through holes 8 are arranged longitudinally. The long through holes 8 are used with bolts to connect the tooling base plate 1 to the worktable of the saw. The long through holes 8 and the bolts can be used to make fine adjustments to the tooling in the front and back directions.

[0025] Two parallel linear guide rails are arranged side by side on the upper end of the tooling base plate 1, and a slide plate 2 is installed on the linear guide rails to ensure that the slide plate 2 slides smoothly and without jamming in the lateral direction.

[0026] An L-shaped seat 9 is installed on the upper end of the tooling base plate 1 on one side of the slide plate 2. A horizontally arranged limiting bolt 10 is screwed onto the upper part of the L-shaped seat 9. A locking nut 11 is screwed onto the limiting bolt 10. The maximum stroke of the slide plate 2 is controlled by adjusting the extension of the locking nut 11.

[0027] The support 6 has an inverted T-shaped structure. The two sides of the lower end of the support 6 are provided with support columns 25. The two support columns 25 are fixed to the two sides of the rear end of the cylinder base 4 by long bolts 26. The front push device 5 is located between the two support columns 25.

[0028] The front lifting device 5 includes a front lifting cylinder 20, a cylinder mounting base 21, and a front lifting block 22. The front lifting cylinder 20 is fixed to the slide plate 2 via the cylinder mounting base 21. The piston rod of the front lifting cylinder 20 is connected to the front lifting block 22. A guide rod 24 is installed on each side of the piston rod of the front lifting cylinder 20 on the front lifting block 22. The two guide rods 24 are slidably connected to the two sides of the cylinder mounting base 21. Guide sleeves 23 that cooperate with the guide rods 24 are provided on both sides of the cylinder mounting base 21. The guide sleeves 23 cooperate with the guide rods 24 to guide the front lifting block 22 to move back and forth stably.

[0029] The specific workflow of this fixture is as follows: First, fix the fixture base plate 1 on the worktable of the saw. Then, place the compressor cylinder 27 into the cavity 12 at the upper end of the cylinder base 4. The side walls of the compressor cylinder 27 are supported by the support surfaces 13 on both sides of the upper end of the cavity 12. The front mounting post 29 at the bottom of the compressor cylinder 27 is placed on the front step 15, and the rear mounting post 30 at the bottom of the compressor cylinder 27 is placed on the rear step 17. Move the compressor cylinder 27 forward, and the limiting protrusion 18 is inserted between the two reinforcing ribs 31. Then, the ball-head plungers 19 on both sides of the cavity 12 are correspondingly engaged with the rear mounting post 30. The compressor cylinder 27 is now installed in the holes 32 on both sides of the mounting column 30. The quick-clamp 7 is then engaged to press the top of the compressor cylinder 27, securing it in place. Next, the front push cylinder 20 is activated, extending its piston rod to control the front push block 22 to push forward against the rear end of the compressor cylinder 27, preventing it from retracting. The saw is then started, with the saw blade vertically positioned. The power cylinder 3 is activated, pushing the slide plate 2 and the fixed compressor cylinder 27 towards the saw blade, which cuts off the end gate waste 28. After cutting, the saw is turned off, and the power cylinder 3 controls the slide plate 2 and compressor cylinder 27 to reset. The front push cylinder 20 controls the front push block 22 to reset backward. The quick-clamp 7 is then opened, and the compressor cylinder 27 is removed.

[0030] The ball head of the ball plunger 19 is engaged with the hole 32 of the rear mounting post 30. When the compressor cylinder 27 is removed after the subsequent machining, the ball head of the ball plunger 19 can be disengaged from the hole 32 of the rear mounting post 30 with just a little more force.

[0031] Both sides of the front step 15 and both sides of the rear step 17 are provided with part-removing slots 16, through which the processed compressor cylinder 27 can be removed more quickly.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] The above provides a detailed description of a cutting fixture for removing waste material from the gate of a compressor cylinder block. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
