Description

Technical Field

[0001] The utility model relates to the field of chamfer detection, in particular to a compressor piston chamfer detector. Background Art

[0002] The compressor piston reciprocates in the cylinder and forms the compression volume with the cylinder. Its shape is complementary to the cylinder. Once the cylinder form is determined, the piston is also determined accordingly. The piston needs to be chamfered at the top after production. In order to ensure the quality of the chamfer, it is usually picked up by personnel for visual inspection;

[0003] The existing piston chamfer detection method is time-consuming and labor-intensive. Personnel are easily fatigued during visual inspection. There are no suitable reference objects at the chamfered parts, making it difficult to ensure the detection quality and having low practicality. In order to solve the above problems, we propose a compressor piston chamfer detector. Utility Model Content

[0004] The utility model aims to provide a compressor piston chamfer detector, which solves the problem that the existing piston chamfer detection is time-consuming and labor-intensive and difficult to ensure the detection quality.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a compressor piston chamfer detector, including a shell, the top of the shell is rotatably connected to a mounting plate, the top of the mounting plate is welded with a fixing screw, the surface of the fixing screw is slidably sleeved with a chamfer reference piece that fits the mounting plate, the surface of the fixing screw is threadedly connected with a fixing nut, a lighting strip is installed inside the shell, a battery box is bolted inside the shell, and an observation port is opened on the top of the chamfer reference piece.

[0006] The adoption of the above technical solution can improve the accuracy of detection of the chamfer of the piston. It is simple and convenient to operate and has good flexibility. At the same time, it can have an auxiliary lighting function and provide a bright line of sight in a dimly lit environment, which is beneficial for personnel to observe and has high practicality.

[0007] The utility model is further configured as follows: a support plate is fixedly sleeved on the surface of the mounting plate.

[0008] By adopting the above technical solution, the chamfer reference piece can be supported by setting the support plate, thereby increasing the support area and support stability of the chamfer reference piece.

[0009] The utility model is further configured as follows: a hexagonal limiting groove is provided on the top of the fixing screw.

[0010] By adopting the above technical solution, through the setting of the hexagonal limit groove, it is convenient for personnel to install and disassemble the fixing nut. By using the cooperation of the hexagonal wrench and the hexagonal limit groove, the fixing screw can be limited to prevent the fixing screw from rotating during the disassembly process.

[0011] The utility model is further configured as follows: a cover plate is bolted to the bottom of the shell, and a push switch is installed at the bottom of the cover plate.

[0012] By adopting the above technical solution and setting the cover plate, it is convenient for personnel to install and maintain the components inside the shell.

[0013] The utility model is further configured as follows: the fixing screw and the fixing nut are both made of stainless steel.

[0014] By adopting the above technical solution, the fixing screw and the fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0015] The utility model is further configured as follows: the shell is made of a light-transmitting acrylic material.

[0016] By adopting the above technical solution, the shell has the characteristics of high plasticity, good transparency and excellent weather resistance.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model places the piston on the inspection table with the chamfer facing upwards, then picks up the housing and places it in the piston. After the housing is placed to the bottom, the inclined surface of the chamfer reference piece fits with the chamfer of the piston, and then the chamfer reference piece is rotated for observation from the observation port, thereby improving the accuracy of the inspection of the chamfer of the piston, and the operation is simple and convenient with good flexibility.

[0019] 2. The utility model presses the push switch at the bottom of the cover plate by hand, and after the push switch is pressed, the battery box and the lighting strip will be energized. After the lighting strip is energized, the current will enter the circuit distribution to generate bright light, and after the light is formed, it will be transmitted upward through the observation port to the outside. With the help of the bright light, the personnel can clearly observe the fit between the chamfered reference part and the chamfer of the piston. It can have an auxiliary lighting function, and can provide a bright line of sight in a dimly lit environment, which is conducive to observation by personnel and is highly practical.
