Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning compressor cylinders, specifically a precision machining positioning device for air-conditioning compressor cylinders. Background Art

[0002] An air-conditioning compressor plays a role in compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The air-conditioning compressor is generally installed in the outdoor unit. The air-conditioning compressor extracts the refrigerant from the low-pressure area, compresses it and then sends it to the high-pressure area for cooling and condensation. Heat is dissipated into the air through the radiator fins, and the refrigerant also changes from a gaseous state to a liquid state, with the pressure increasing. In the working circuit of the air-conditioning compressor, there are an evaporation area (low-pressure area) and a condensation area (high-pressure area). During the processing and production process, the cylinder block of an automotive air-conditioning compressor needs to be machined with cylinder holes. To ensure the machining quality of the cylinder holes, it is necessary to clamp and position the cylinder block of the automotive air-conditioning compressor.

[0003] After retrieval, the existing patent [CN 216576781 U] discloses a machining positioning device for an air-conditioning compressor cylinder block, including a mounting plate. A base is fixed on the top of the mounting plate. A slide rail is provided at the top end of the base. A sliding connector is connected inside the slide rail. A processing table is connected to the top of the sliding connector. Side plates are fixed on the left and right sides of the processing table. A drive box is connected to the outer ends of the side plates. A drive structure is installed inside the drive box. A moving plate is connected to one side of the drive structure located on the side of the side plate. A pressing plate is connected to the right side of the moving plate. Four corners on the side of the moving plate close to the pressing plate are provided with positioning columns. A receiving box is fixed on the side of the side plate close to the moving plate. By setting the drive structure, the moving plate and the pressing plate, the cylinder block can be limited and fixed, achieving the effect of accurately positioning the cylinder block and making the device more efficient during use. This positioning device solves the problem of being unable to firmly fix the cylinder block.

[0004] Although the above-mentioned utility model patent solves the problem of being unable to firmly fix the cylinder block, this patent does not have the function of facilitating the clamping and positioning of the air-conditioning compressor cylinder. During use, if it is not convenient to clamp and position the cylinder, it will cause the cylinder to not be accurately fixed in the predetermined position, resulting in deviations in the cooperation of internal components, thereby reducing the working efficiency and performance stability of the compressor, making the practicability of this device poor. Moreover, it does not have the function of facilitating the installation and fixation of this device on the body frame of the compressor. During use, if it is not convenient to install and fix this device, it will lead to the situation that professional personnel or a long time is required to install and fix this device, making the installation convenience of this device poor.

The installation and fixing mechanism 3 is used to install and fix this device on the body frame. Then, this device can be used to clamp and position the cylinder. The clamping and positioning mechanism 2 is used to clamp and position the air-conditioning compressor cylinder, thus completing the work.

[0025] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a clamping and positioning mechanism 2 is arranged inside the support block 1. The clamping and positioning mechanism 2 includes a first sliding groove 201. The first sliding groove 201 is opened inside the support block 1.

A moving plate 208 is fixedly connected to one side of the second sliding block 207. A support plate 209 is fixedly connected to the top of the support block 1. An electric push rod 210 is fixedly connected to one side of the support plate 209. One end of the electric push rod 210 is fixedly connected to one side of the moving plate 208. A clamping plate 211 is fixedly connected to the other side of the first sliding block 203. The number of the first sliding blocks 203 is two, and the two first sliding blocks 203 are symmetrically arranged with the vertical center line of the support block 1 as the axis of symmetry. The number of the fixing blocks 204 is two, and the two fixing blocks 204 are symmetrically arranged with the vertical center line of the support block 1 as the axis of symmetry. The vertical center line of the support plate 209 coincides with the vertical center line of the support block 1. The support plate 209 is used to support the electric push rod 210.

[0026] Among them: when it is necessary to use this device to clamp and position the cylinder, at this time, start the electric push rod 210 to make the electric push rod 210 start to extend.
