Description

Technical Field

[0001] This utility model relates to the field of compressor bearing testing technology, specifically a device for testing the inner and outer diameters of compressor bearings. Background Technology

[0002] Air conditioner compressor bearings are one of the important components of an air conditioner compressor. During the production of air conditioner compressor bearings, their inner and outer diameters need to be tested.

[0003] Existing compressor bearing inner and outer diameter detection devices, such as the air conditioning compressor bearing inner and outer diameter synchronous detection device with announcement number CN220959991U, first use a clamping block to center and clamp the compressor bearing, and then use a pushing mechanism to put the detection chamber on the compressor bearing to realize the measurement of the inner and outer diameters of the compressor bearing.

[0004] The above-mentioned device still has shortcomings. First, the operation steps are relatively complicated, requiring mechanical centering and then pushing the detection chamber to move and fit onto the compressor bearing, resulting in low measurement efficiency. Second, the size of the detection chamber is limited, and it cannot measure compressor bearings larger than the size of the detection chamber, thus limiting the detection range.

[0005] To address the aforementioned issues, an improved device for detecting the inner and outer diameters of compressor bearings is now designed. Utility Model Content

[0006] The purpose of this invention is to provide a device for detecting the inner and outer diameters of compressor bearings, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A compressor bearing inner and outer diameter detection device includes a base, a housing vertically mounted on the upper end of the base, a top plate horizontally mounted on the upper end of one side wall of the housing, a vertically formed groove on the side wall of the housing where the top plate is located, an I-shaped slider slidably connected to the inner wall of the groove, a fixing column for placing the compressor bearing horizontally mounted on the side wall of the I-shaped slider away from the housing, a drive mechanism for moving the fixing column upward to cooperate with the top plate to clamp the compressor bearing inside the housing, and a measuring mechanism for detecting the thickness and outer diameter of the compressor bearing on the drive mechanism and the housing.

[0009] As a further embodiment of this utility model: the driving mechanism includes an electric telescopic rod, which is vertically installed at the bottom of the housing. A control button for controlling the extension and retraction of the electric telescopic rod is installed on the upper end of the base. A movable plate is horizontally installed at the output end of the electric telescopic rod. The movable plate is fixedly connected to the I-shaped slider near the side wall of the slide groove.

[0010] As a further embodiment of this utility model: the measuring mechanism includes a second laser rangefinder. The lower end of the top plate is on the same horizontal plane as the top of the housing. The second laser rangefinder is installed on the upper end of the moving plate. The measuring end of the second laser rangefinder is on the same horizontal plane as the upper end of the fixed column. The purpose is to make the data measured by the second laser rangefinder the thickness of the compressor bearing. A base plate is horizontally installed on the upper end of the base directly below the top plate. A first laser rangefinder for measuring the lower end height of the compressor bearing is installed on the upper end of the base plate near the housing. The first laser rangefinder is located directly below the fixed column. Since the height of the lower end of the top plate is known, the height of the lower end of the top plate minus the lower end height of the compressor bearing measured by the first laser rangefinder is the diameter of the compressor bearing. A processor for analyzing and processing the data measured by the second laser rangefinder and the first laser rangefinder is installed on the upper end of the top plate. A display for displaying the inner and outer diameter data of the compressor bearing is vertically installed on the upper end of the top plate away from the housing. All electrical components are powered by an external power supply.

[0011] As a further embodiment of this utility model: a rotating cylinder is rotatably connected to the side wall of the fixed column to facilitate the movement of the fixed column to the top of the compressor bearing, and the measuring end of the second laser rangefinder is on the same horizontal plane as the upper end of the rotating cylinder.

[0012] As a further improvement of this utility model: on both sides of the box sidewalls of the I-shaped slider, there are vertically installed limiting plates for reducing the friction between the compressor bearing and the box sidewalls, and the first laser rangefinder is set on the upper part of the base plate near the limiting plate.

[0013] As a further improvement of this utility model, a friction rubber pad is installed at the lower end of the base to facilitate stable placement of the base.

[0014] As a further improvement of this utility model: the top plate and the box body are fixedly connected together by welding, and the side wall of the top plate is equipped with reinforcing support ribs to improve the structural strength of the top plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention involves directly mounting the compressor bearing onto a fixed column. Utilizing the compressor bearing's own weight, the upper end of the fixed column is positioned at the top of the compressor bearing. The fixed column is then moved, clamping and fixing the compressor bearing to the top plate. At this point, the thickness of the compressor bearing can be measured using a second laser rangefinder, and the height of the lower end of the compressor bearing can be measured using a first laser rangefinder. Since the height of the lower end of the top plate is known, the inner and outer diameter data of the compressor bearing can be quickly obtained. The structure is simple, the measurement efficiency is high, the measurement range is unrestricted, and it is convenient for users. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 In this embodiment of the present invention, a compressor bearing inner and outer diameter detection device includes a base 1, a housing 2 vertically mounted on the upper end of the base 1, a top plate 4 horizontally mounted on the upper end of one side wall of the housing 2, a vertically formed groove 15 on the side wall of the housing 2 where the top plate 4 is located, an I-shaped slider 16 slidably connected to the inner wall of the groove 15, a fixing column 8 for placing the compressor bearing horizontally mounted on the side wall of the I-shaped slider 16 away from the housing 2, a drive mechanism for moving the fixing column 8 upward to cooperate with the top plate 4 to clamp the compressor bearing inside the housing 2, and a measuring mechanism for detecting the thickness and outer diameter of the compressor bearing on the drive mechanism and the housing 2.

[0024] The driving mechanism includes an electric telescopic rod 12, which is vertically installed at the bottom of the housing 2. A control button 11 for controlling the extension and retraction of the electric telescopic rod 12 is installed on the upper end of the base 1. A moving plate 13 is horizontally installed at the output end of the electric telescopic rod 12. The side wall of the moving plate 13 near the slide groove 15 is fixedly connected to the I-shaped slider 16.

[0025] The measuring mechanism includes a second laser rangefinder 14. The lower end of the top plate 4 is on the same horizontal plane as the top of the housing 2. The second laser rangefinder 14 is mounted on the upper end of the moving plate 13. The measuring end of the second laser rangefinder 14 is on the same horizontal plane as the upper end of the fixed column 8. The purpose is to ensure that the data measured by the second laser rangefinder 14 is the thickness of the compressor bearing. A base plate 9 is horizontally mounted on the upper end of the base 1 directly below the top plate 4. A first laser rangefinder 1 for measuring the lower end height of the compressor bearing is mounted on the upper end of the base plate 9 near the housing 2. 0. The first laser rangefinder 10 is located directly below the fixed column 8. Since the height of the lower end of the top plate 4 is known, the diameter of the compressor bearing is obtained by subtracting the height of the lower end of the compressor bearing measured by the first laser rangefinder 10 from the height of the lower end of the top plate 4. A processor 5 is installed on the upper end of the top plate 4 to analyze and process the data measured by the second laser rangefinder 14 and the first laser rangefinder 10. A display 6 for displaying the inner and outer diameter data of the compressor bearing is vertically installed on the side of the upper end of the top plate 4 away from the housing 2. All electrical components are powered by an external power supply.

[0026] A rotating cylinder 7 is rotatably connected to the side wall of the fixed column 8 to facilitate the movement of the fixed column 8 to the top of the compressor bearing. The measuring end of the second laser rangefinder 14 is on the same horizontal plane as the upper end of the rotating cylinder 7.

[0027] On both sides of the I-shaped slider 16, there are vertically installed limiting plates 3 to reduce the friction between the compressor bearing and the side wall of the box 2. The first laser rangefinder 10 is set on the upper end of the base plate 9 near the limiting plate 3.

[0028] Working principle of a compressor bearing inner and outer diameter detection device:

[0029] During measurement, the operator places the compressor bearing onto the rotating cylinder 7 and makes the compressor bearing fit tightly against the side wall of the limiting plate 3. Under the action of gravity, the top of the compressor bearing will move to the upper end of the rotating cylinder 7.

[0030] Then, the electric telescopic rod 12 is extended by controlling button 11. The output end of the electric telescopic rod 12 pushes the moving plate 13 to move upward. The moving plate 13 drives the second laser rangefinder 14, the I-shaped slider 16, the fixed column 8, and the rotating cylinder 7 to move upward. The rotating cylinder 7 drives the compressor bearing to move upward, so that the rotating cylinder 7 and the top plate 4 clamp the compressor bearing. At this time, the data measured by the second laser rangefinder 14 is the thickness of the compressor bearing, and the first laser rangefinder 10 measures the height of the lower end of the compressor bearing.

[0031] The second laser rangefinder 14 and the first laser rangefinder 10 transmit the measured data to the processor 5 for analysis and processing. Specifically:

[0032] The outer diameter of the compressor bearing is: the height of the lower end of the top plate 4 minus the data value measured by the first laser rangefinder 10.

[0033] The inner diameter of the compressor bearing is: the outer diameter of the compressor bearing minus twice the data value measured by the second laser rangefinder 14.

[0034] Then, processor 5 transmits the processed data to display 6 for display.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
