Description

Technical Field

[0001] The utility model relates to the technical field of road monitoring, in particular to a processing and positioning device for cylinder parts of air-conditioning compressors. Background Art

[0002] For the slender cylindrical parts in air-conditioning compressors, boring machines are generally used for processing. However, the processing cost of boring machines is too high. In order to reduce the processing cost, lathes are often used for turning the parts.

[0003] When processing the surface of thin-walled cylindrical parts, chuck positioning and clamping are generally used. For safety reasons, operators often use a large clamping force, which causes the parts to deform before processing. After processing, the parts release the energy generated by clamping, which reduces the size and shape accuracy of the parts. However, cylindrical parts require high precision and small runout, which cannot meet the matching accuracy between cylindrical parts and their mating parts, affecting the performance, sealing, reliability and life of the assembly.

[0004] In view of the above problems, an innovative design is carried out on the basis of the original positioning device. Utility Model Content

[0012] The utility model provides a processing and positioning device for cylinder parts of air-conditioning compressors, which has the following beneficial effects:

[0013] The cylinder part is sleeved on the outside of the stabilizing ring. By turning the adjusting rod, the adjusting rod can drive the second driving gear to rotate through the first driving gear, which is convenient for the second driving gear to drive the driving rod to rotate.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure. For example, if the device in the accompanying 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.

[0026] See also Figure 1-Figure 4The utility model provides a technical solution: a processing and positioning device for cylinder parts of air-conditioning compressors, comprising: a workbench 1, a tray 2 is installed above the workbench 1, a column 3 is arranged on the surface of the tray 2, an adjusting rod 4 is installed on the inner side of the column 3, a first driving gear 5 is fixed on the surface of the adjusting rod 4, a second driving gear 6 is connected to the outer side of the first driving gear 5, a driving rod 7 is installed on the second driving gear 6, a tightening rod 8 is installed on the outer side of the driving rod 7, a stabilizing ring 10 is arranged on the outer side of the column 3, a through hole 11 is opened on the stabilizing ring 10, the tightening rod 8 is located in the through hole 11, and a crossbeam 12 is installed between the stabilizing ring 10 and the column 3.

[0027] In this example, the pallet 2 and the workbench 1 are rotatably connected, and the pallet 2 and the column 3 are fixedly connected, which makes it convenient to push the pallet 2 to drive the column 3 to rotate on the workbench 1, which is beneficial for the column 3 to subsequently drive the cylindrical parts to rotate, making it convenient to process the parts.

[0028] In this example, the adjusting rod 4 and the column 3 are rotationally connected, and the second driving gear 6 is distributed at equal angles on the outside of the adjusting rod 4. The second driving gear 6 and the first driving gear 5 are meshed with each other. When the adjusting rod 4 is turned to rotate, the rotating adjusting rod 4 can push the second driving gear 6 to rotate synchronously through the first driving gear 5.

[0029] The driving rod 7 in this example is rotatably connected to the column 3, and a thread is provided on the surface of the driving rod 7. The driving rod 7 and the tightening rod 8 are threadedly connected. When the second driving gear 6 rotates, the second driving gear 6 can drive the driving rod 7 to rotate synchronously, so that the driving rod 7 can push the tightening rod 8 through the thread for telescopic adjustment.

[0030] In this example, a rubber block 9 is installed at the end of the clamping rod 8 away from the driving rod 7, which is conducive to the clamping rod 8 driving the rubber block 9 to press against the inner wall of the cylindrical part, thereby improving the friction between the clamping rod 8 and the cylindrical part. At the same time, the rubber block 9 can also deform to adapt to the curvature of the inner wall of the cylindrical part, thereby improving the stability of the clamping of the cylindrical part.

[0031] The surface of the clamping rod 8 in this example is a rectangular parallelepiped structure, and the clamping rod 8 is connected to the stabilizing ring 10 through a through-hole 11 for through-sliding connection, so as to facilitate stable telescopic adjustment of the clamping rod 8 on the stabilizing ring 10 and prevent the clamping rod 8 from rotating synchronously with the driving rod 7.

[0032] Working principle: According to Figure 1-Figure 4As shown, the cylindrical part that needs to be turned is sleeved on the outside of the stabilizing ring 10, and then the tray 2 is held and the adjusting rod 4 is turned to rotate. At this time, the adjusting rod 4 rotates in the column 3, and the rotating adjusting rod 4 drives the second driving gear 6 to rotate through the first driving gear 5. At this time, the second driving gear 6 drives the driving rod 7 to rotate, and the rotating driving rod 7 drives the tightening rod 8 to move through the thread. At this time, the tightening rod 8 is adjusted to move on the stabilizing ring 10 through the perforation 11 under the pushing action of the driving rod 7, until the tightening rod 8 drives the rubber block 9 to press against the inner wall of the cylindrical part. At this time, the cylindrical part is stably positioned on the outside of the column 3 through the pushing action of the tightening rod 8, which is convenient for processing. At the same time, it can also drive the column 3 to rotate by pushing the tray 2, so that the column 3 can drive the cylindrical part to rotate around the axis, which is convenient for surface processing of the cylindrical part.
