Description

Technical Field

[0001] This utility model belongs to the field of compressor manufacturing technology, specifically a tooling for positioning the flatness of the mounting lugs on the side of the compressor cylinder head. Background Technology

[0002] During the process of tightening the cylinder head of the compressor, the lack of constraint on the cylinder body during tightening can easily lead to positional displacement of the cylinder body, resulting in substandard flatness. Therefore, a flatness inspection process is required. However, during the overall flatness inspection, the compressor is first tightened. After tightening, the operator removes the compressor from the line and uses an off-line flatness inspection fixture to check the overall flatness. If the flatness is found to be substandard, a rubber mallet is used to tap the mounting surface of the compressor to ensure it meets the required flatness standard.

[0003] This method has many drawbacks:

[0004] 1. Positioning and tightening operations rely on manual labor, increasing labor costs, and there is a lack of precise positioning of the cylinder block and cylinder head;

[0005] 2. The overall quality of the compressor is difficult to guarantee, and manual operation is highly arbitrary, making it difficult to ensure that each adjustment is accurate and effective, resulting in frequent flatness problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is:

[0007] How to solve the quality problem of non-flatness caused by positional misalignment during the tightening of the cylinder head of the existing compressor.

[0008] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:

[0009] The compressor cylinder head side mounting lug plane positioning fixture includes two sets of symmetrically distributed clamping units. Each clamping unit includes a horizontally adjustable vertical side mounting plate. The vertical side mounting plate is equipped with a horizontally set upper positioning structure and a lower positioning structure. The two sets of upper positioning structures are used to position the cylinder body, and the two sets of lower positioning structures are used to position the lower cylinder head.

[0010] In a more preferred embodiment, the lower positioning structure includes a lower side plate and a cylinder head positioning component mounted on the lower side plate.

[0011] The cylinder head positioning component and the cylinder block positioning component are arranged in parallel, and the lengths of the cylinder head positioning component and the cylinder block positioning component are adjustable.

[0012] In a more preferred embodiment, the lower side plate is provided with a vertical guide groove on its side.

[0013] One end of the cylinder head positioning component is provided with a sliding block, which slides in conjunction with the vertical guide groove. A locking component is installed on the sliding block to fix the sliding block in a certain position within the vertical guide groove.

[0014] In a more preferred embodiment, both the cylinder head positioning component and the cylinder block positioning component are telescopic structures.

[0015] In a more preferred embodiment, the telescopic structure includes a fixed part, a movable part, and a locking part. The locking part is mounted on the fixed part and includes a paddle rotatably mounted on the fixed part. A cam is fixed at the rotation node of the paddle. A radial stepped groove is provided on the fixed part. A connecting post and a spring fitting fitted on the outside of the connecting post are installed in the radial stepped groove. A backstop strip is connected to the bottom of the connecting post. An axial groove is provided on the surface of the movable part. The backstop strip and the axial groove are positioned correspondingly and are adapted to each other.

[0016] In a more preferred embodiment, the vertical mounting plate has an adjustment groove on its side, a constraint plate is mounted on the top of the vertical mounting plate, an adjustment component is mounted on the constraint plate, and one end of the cylinder positioning component is slidably fitted in the adjustment groove. The adjustment component is used to adjust the position of the cylinder positioning component in the adjustment groove.

[0017] In a more preferred embodiment, both the cylinder head positioning component and the cylinder block positioning component are rotatably mounted with anti-rotation bodies at their ends. The anti-rotation bodies have an L-shaped structure and a torsion spring is installed at the rotation node position.

[0018] In a more preferred embodiment, polyurethane gaskets are installed at the ends of both the cylinder head positioning component and the cylinder block positioning component.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This utility model uses two sets of clamping units to position the cylinder body and the lower cylinder head. The cylinder body and the lower cylinder head are clamped by the lateral adjustable position of the clamping units. After the cylinder body and the lower cylinder head are clamped, the tightening operation is carried out by the tightening mechanism at the top, thereby ensuring the flatness of the whole machine.

[0021] 2. The lengths of the cylinder head positioning component and the cylinder block positioning component are adjustable. The cylinder block and the lower cylinder head are positioned to prevent rotation by means of an anti-rotation body. At the same time, a certain angle of rotation can be achieved to adapt to the outer wall surface of the cylinder block or cylinder head. The polyurethane gasket is used to avoid damage to the outer wall surface. The anti-rotation body is used to prevent relative rotation during the tightening operation.

[0022] 3. This utility model adapts to the tightening operation of compressors of different specifications by adjusting the cylinder head positioning component and the cylinder block positioning component laterally. At the same time, the height of the cylinder block positioning component can be adjusted by adjusting the adjusting component and adjusting groove, and the height of the cylinder head positioning component can be adjusted by the vertical guide groove, sliding block and locking component, thus adapting to the tightening operation of compressors of different specifications.

[0035] Example 1

[0036] like Figure 1 As shown, the compressor cylinder head side is equipped with a lug plane positioning fixture, which includes two sets of symmetrically distributed clamping units 10.

[0037] The clamping unit 10 includes a horizontally adjustable vertical side mounting plate 11. The power source is a cylinder mounted on the back. The vertical side mounting plate 11 is equipped with horizontally arranged upper and lower positioning structures. The two sets of upper positioning structures are used to position the cylinder body, and the two sets of lower positioning structures are used to position the lower cylinder head.

[0038] Positioning fixtures are distributed on both sides above the online conveyor chain. Conveying fixtures are arranged on the online conveyor chain. The cylinder drives two clamping units 10 to move closer to each other. The upper positioning structure positions and clamps the cylinder body, and the lower positioning structure positions and clamps the lower cylinder cover. In this way, the top cover, cylinder body and lower cylinder cover are tightened by the tightening mechanism at the top.

[0039] Example 2

[0040] In Embodiment 1, the upper positioning structure includes a cylinder positioning component 12;

[0041] like Figure 2 , 3 As shown, the lower positioning structure includes a lower side plate 13 and a cylinder head positioning member 14 mounted on the lower side plate 13;

[0042] The cylinder head positioning component 14 and the cylinder block positioning component 12 are arranged in parallel, and the lengths of the cylinder head positioning component 14 and the cylinder block positioning component 12 are adjustable. The length can be adjusted by means of thread, pneumatic, hydraulic, etc.

[0043] The cylinder block positioning component 12 and the cylinder head positioning component 14 respectively clamp and fix the corresponding lower cylinder head and cylinder block to avoid rotation during the tightening operation. The length of the cylinder head positioning component 14 and the cylinder block positioning component 12 can be adjusted to adapt to different compressor specifications.

[0044] Example 3

[0045] In Example 2, as Figure 8 He En Figure 9 As shown, a vertical guide groove 131 is provided on the side of the lower side plate 13;

[0046] One end of the cylinder head positioning component 14 is provided with a sliding block 141, which is slidably engaged with the vertical guide groove 131. A locking component 142 is installed on the sliding block 141, which is used to fix the sliding block 141 at a certain position in the vertical guide groove 131.

[0047] By loosening the locking member 142, the sliding block 141 and the vertical guide groove 131 are loosened. After the cylinder head positioning member 14 is adjusted to the target position in the vertical guide groove 131, the locking member 142 is tightened to press the sliding block 141 and the cylinder head positioning member 14 onto the lower side plate 13, thereby adapting to different specifications of compressors.

[0048] like Figures 2 to 5 As shown, both the cylinder head positioning component 14 and the cylinder block positioning component 12 are telescopic structures. The telescopic structure includes a fixed part 15, a movable part 16, and a locking part 17. The locking part 17 is mounted on the fixed part 15 and includes a paddle 171 rotatably mounted on the fixed part 15. A cam is fixed at the rotation node of the paddle 171. A radial stepped groove 172 is provided on the fixed part 15. A connecting post 173 and a spring component 175 fitted on the outside of the connecting post 173 are installed in the radial stepped groove 172. A backstop strip 174 is connected to the bottom of the connecting post 173. An axial groove 176 is provided on the surface of the movable part 16. The backstop strip 174 and the axial groove 176 are corresponding and adapted to each other.

[0049] When the length needs to be adjusted, the movable part 16 is rotated outward relative to the fixed part 15 by rotating the paddle 171 outward, and the anti-reverse strip 174 is pressed and fixed in the axial groove 176 by the cam, thereby fixing the movable part 16 and the fixed part 15 relative to each other to obtain the required length.

[0050] like Figure 6 and Figure 7 As shown, the vertical mounting plate 11 has an adjustment groove 111 on its side and a constraint plate 112 on its top. An adjustment component 113 is rotatably mounted on the constraint plate 112 via a bearing. One end of the cylinder positioning component 12 is slidably fitted in the adjustment groove 111. The adjustment component 113 is used to adjust the position of the cylinder positioning component 12 in the adjustment groove 111.

[0051] When it is necessary to adjust the height of the cylinder positioning component 12, the top thread of the adjusting component 113 and the cylinder positioning component 12 is connected. The adjusting component 113 is rotated to adjust its length to match the length of the cylinder positioning component 12, thereby adjusting the cylinder positioning component 12 to the required height, thus adapting to the tightening operation of compressors of different specifications.

[0052] In practice, the cylinder head positioning member 12 is connected to the top of the adjusting member 113 by a threaded connection. The adjusting member 113 is rotated to adjust its length to match the length of the cylinder head positioning member 12, thereby adjusting the cylinder head positioning member 12 to the required height. The sliding block 141 and the vertical guide groove 131 are loosened by loosening the locking member 142. After the cylinder head positioning member 14 is adjusted to the target position in the vertical guide groove 131, the locking member 142 is tightened to press the sliding block 141 and the cylinder head positioning member 14 onto the lower side plate 13. The movable part 16 is positioned relative to the fixed part 15 by rotating the paddle 171 outward and using the cam to press and fix the anti-reverse strip 174 in the axial groove 176, thereby fixing the movable part 16 and the fixed part 15 relative to each other to obtain the required length.

[0053] The cylinder drives the two clamping units 10 to move closer to each other. The upper positioning structure positions and clamps the cylinder body, and the lower positioning structure positions and clamps the lower cylinder cover. In this way, the top cover, cylinder body and lower cylinder cover are tightened by the top tightening mechanism. After completion, the cylinder drives the clamping unit 10 to reset.

[0054] Example 4

[0055] In Example 2, as Figure 2 and Figure 3 As shown, anti-rotation bodies 18 are rotatably mounted on the ends of both the cylinder head positioning member 14 and the cylinder block positioning member 12. The anti-rotation body 18 has an L-shaped structure and a torsion spring is installed at the rotation node position.

[0056] A polyurethane gasket 181 is installed on the side of the anti-rotation body 18 opposite to the compressor.

[0057] When the cylinder head positioning component 14 and the cylinder block positioning component 12 approach the outer wall of the cylinder block or the lower cylinder head, they will rotate, compressing the torsion spring. The polyurethane gasket 181 applies pressure to the outer wall of the cylinder block or the lower cylinder head, while preventing the cylinder block or the lower cylinder head from rotating, thus ensuring the flatness of the entire machine.

[0058] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
