Description

Technical Field

[0001] This utility model relates to the field of compressor testing technology, specifically a compressor test bench with a protective structure. Background Technology

[0002] A compressor test bench is a specialized equipment system for testing the performance, quality, and research and development of compressors. It simulates the operating conditions of a compressor under actual working conditions, collects and analyzes relevant data to evaluate the compressor's performance indicators, reliability, and safety.

[0003] Publication number CN221547265U discloses a compressor testing device. By setting up a clamping assembly, it achieves the purpose of clamping and fixing the compressor by using a drive device to drive the clamping assembly, preventing the compressor from shaking during testing and affecting the test data. However, this patent still has the following problems in actual use:

[0004] When fixing the compressor before testing, it can only be fixed longitudinally. This may cause the compressor to sway laterally during testing, which may cause the compressor to move laterally or even slip off the device, thus posing a risk of damage.

[0005] A compressor test bench with a protective structure is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a compressor test bench with a protective structure to solve the problem mentioned in the background art that, when fixing the compressor before testing, it can only be fixed longitudinally. This results in the compressor potentially generating a lateral swaying force during testing, causing the compressor to sway laterally, move laterally, or even slip off the device, posing a risk of damage to the compressor.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a compressor test bench with a protective structure, comprising a device body and a support plate installed on the top surface of the device body;

[0008] Also includes:

[0009] The device body is equipped with a clamping assembly, which includes a servo motor. The servo motor is fixedly installed inside the device body, and a disc is rotatably connected to one side of the device body. The output end of the servo motor is fixedly connected to the disc, and the support plate is U-shaped and located above the disc.

[0010] Among them, the top of the disc is symmetrically fixed with connecting columns, and the top of the device body is symmetrically fixed with connecting plates. One side of the connecting plate is fixedly connected with a first telescopic rod, and the telescopic end of the first telescopic rod is fixedly connected with a moving block.

[0011] The movable block has a groove inside, and the connecting column slides inside the groove.

[0012] Preferably, a movable plate is fixedly connected to the front of the movable block, and a spring is fixedly connected to the front of the movable plate.

[0013] Preferably, a compression plate is fixedly connected to the front of the spring, and a second telescopic rod is symmetrically fixed between the compression plate and the moving plate.

[0014] Preferably, the movable plate has symmetrical mounting pieces on its front side, and the mounting pieces have internal rotation limiting strips.

[0015] Preferably, the limiting strip is L-shaped, and a pressing block is fixedly connected to one side of the limiting strip, and the pressing block abuts against the pressing plate.

[0016] Preferably, the front of the movable plate is symmetrically provided with adjustment components. The adjustment components include limiting blocks, which are fixedly connected to the movable plate and are symmetrically provided in two. A slider is slidably connected between the limiting blocks, and multiple sliding grooves are symmetrically opened inside the limiting blocks. A locking block is slidably connected inside one of the sliding grooves.

[0017] Preferably, the card block is slidably connected to the sliding groove, and is engaged with the slider through the sliding groove, and the slider is fixedly connected to the mounting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This compressor test bench with a protective structure can simultaneously apply fixation to all four sides of the compressor during testing and protection, thereby improving the effectiveness of the fixation and protection during compressor testing and preventing lateral displacement of the compressor, which could cause the compressor to slip off the device body. The specific details are as follows:

[0019] 1. By activating the servo motor, the disc rotates, causing the connecting columns on both sides of the top to move in an arc-shaped trajectory. The distance between the connecting columns gradually decreases, causing the extrusion plate to contact the compressor first. This, in turn, moves the position of the limiting strip. Due to the position of the extrusion plate, it blocks the extrusion block, causing the limiting strip to abut against the front and rear sides of the compressor. This simultaneously fixes all four sides of the compressor to be tested, preventing the compressor from shifting during testing and potentially slipping off the device. This secures the compressor, allowing for testing. Finally, to release the compressor's fixation, simply reverse the servo motor's direction.

[0020] 2. When it is necessary to adjust and fix the compressor according to its length, the clip inside the slider can be pulled out first. Then, slide the slider according to the length of the compressor. The slider will slide, which will cause the mounting plate to slide. The mounting plate will then cause the limit strip to move, which will shorten the distance between the limit strip and the extrusion plate, thus enabling the fixing of compressors of different lengths.

[0028] 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.

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] A compressor test bench with a protective structure includes a device body 1 and a support plate 101 mounted on the top surface of the device body 1. The specific steps for testing the compressor are well-known in the prior art, therefore, the specific operation method for compressor testing will not be elaborated upon here. A clamping assembly 2 is mounted on the device body 1. The clamping assembly 2 includes a servo motor 201, which is fixedly installed inside the device body 1. A disc 202 is rotatably connected to one side of the device body 1, and the output end of the servo motor 201 is fixedly connected to the disc 202. The support plate 101 is U-shaped and located above the disc 202. Connecting columns 203 are symmetrically fixed to the top of the disc 202.

[0031] Furthermore, a connecting plate 204 is symmetrically fixed to the top of the device body 1, and a first telescopic rod 205 is fixedly connected to one side of the connecting plate 204, and a moving block 206 is fixedly connected to the telescopic end of the first telescopic rod 205; for example Figures 1-4 As shown, when the compressor needs to be tested, the compressor to be tested is first placed on the top of the support plate 101. Then, by starting the servo motor 201, the servo motor 201 drives the disc 202 to rotate. Then, the disc 202 drives the connecting columns 203 on both sides of the top to move in an arc trajectory. The vertical distance between the connecting columns 203 on both sides will gradually approach. Then, the connecting columns 203 on both sides will drive the moving blocks 206 on both sides to approach each other. The moving block 206 has a sliding groove 207 inside, and the connecting column 203 slides inside the sliding groove 207.

[0032] A movable plate 208 is fixedly connected to the front of the movable block 206, and a spring 209 is fixedly connected to the front of the movable plate 208. A pressing plate 210 is fixedly connected to the front of the spring 209, and a second telescopic rod 211 is symmetrically fixed between the pressing plate 210 and the movable plate 208. Mounting pieces 212 are symmetrically provided on the front of the movable plate 208, and the mounting pieces 212 have internal rotation limit strips 213, such as... Figure 1 , Figures 4-5As shown, the moving blocks 206 on both sides will drive the moving plates 208 on both sides to move closer to each other. Then, the movement of the moving plates 208 on both sides will cause the pressing plates 210 on both sides to move closer to each other. Then, the pressing plates 210 will first contact the compressor. At this time, the moving plates 208 continue to move, causing the limiting block 301 to move in the opposite direction to the compressor, thereby driving the position of the limiting strip 213 to move towards the compressor. Since the pressing plate 210 has already contacted the compressor, the pressing plate 210 will block the pressing block 214 due to the position of the pressing plate 210, while the moving plates 208 will continue to move.

[0033] Therefore, the left limiting bar 213 will rotate counterclockwise, while the right limiting bar 213 will rotate clockwise. Then, the limiting bar 213 will abut against the front and rear sides of the compressor, thereby simultaneously fixing the compressor to be tested from all sides. This prevents the compressor from shifting during testing, thus preventing displacement or even slipping off the device body 1. This strengthens the fixing and protection of the compressor. Secondly, after the compressor is fixed, the spring 209 will be compressed to its limit, and then the fixed compressor can be tested. Finally, if it is necessary to release the fixing protection of the compressor, the servo motor 201 only needs to run in reverse. The limiting bar 213 is L-shaped, and a pressing block 214 is fixedly connected to one side of the limiting bar 213, and the pressing block 214 abuts against the pressing plate 210.

[0034] The front of the movable plate 208 is symmetrically provided with adjustment components 3. The adjustment components 3 include limiting blocks 301, which are fixedly connected to the movable plate 208 and are symmetrically arranged in two. A slider 302 is slidably connected between the limiting blocks 301. Multiple sliding grooves 303 are symmetrically formed inside the limiting blocks 301, and a locking block 304 is slidably connected inside one of the sliding grooves 303. Figure 5 As shown, when it is necessary to adjust and fix the compressor according to its length, the locking block 304 inside the slider 302 can be pulled out first. Then, the slider 302 can be slid according to the length of the compressor. The slider 302 will slide, thereby causing the mounting piece 212 to slide. The mounting piece 212 will then cause the position of the limiting strip 213 to move, thereby shortening the distance between the limiting strip 213 and the extrusion plate 210. This allows for fixing compressors of different lengths. The locking block 304 is slidably connected to the sliding groove 303 and is engaged with the slider 302 through the sliding groove 303. The slider 302 is fixedly connected to the mounting piece 212.

[0035] Working principle: Before using this compressor test bench with a protective structure, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, when the compressor needs to be tested, the compressor to be tested is placed on top of the support plate 101. Then, by starting the servo motor 201, the servo motor 201 drives the disc 202 to rotate. Then, the disc 202 will drive the connecting columns 203 on both sides of the top to move in an arc trajectory, and the vertical distance between the connecting columns 203 on both sides will gradually approach. Then, the connecting columns 203 on both sides will drive the moving blocks 206 on both sides to approach each other. Then, the moving blocks 206 on both sides will drive the moving plates 208 on both sides to approach each other. Then, the movement of the moving plates 208 on both sides will cause the pressing plates 210 on both sides to approach each other. Then, the pressing plates 210 will contact the compressor first. At this time, the moving plates 208 continue to move, causing the limiting block 301 to move in the opposite direction of the compressor, thereby driving the position of the limiting strip 213 to move towards the compressor. Since the pressing plate 210 has already contacted the compressor, the pressing plate 210 will block the pressing block 214 due to the position of the pressing plate 210, while the moving plate 208 will continue to move.

[0036] Therefore, the left limiting bar 213 will rotate counterclockwise, while the right limiting bar 213 will rotate clockwise. Then, the limiting bars 213 will abut against the front and rear sides of the compressor, thereby simultaneously fixing the compressor to be tested from all sides. This prevents the compressor from shifting during testing, thus avoiding displacement or even slipping off the device body 1. This strengthens the fixing and protection of the compressor. Secondly, after the compressor is fixed, the spring 209 will be compressed to its limit, and then the fixed compressor can be tested. Finally, if it is necessary to release the fixing protection of the compressor, the servo motor 201 only needs to run in reverse.

[0037] When it is necessary to adjust and fix the compressor according to its length, the locking block 304 inside the slider 302 can be pulled out first. Then, the slider 302 can be slid according to the length of the compressor. The slider 302 will slide, thereby causing the mounting plate 212 to slide. The mounting plate 212 will then cause the position of the limiting strip 213 to move, thereby shortening the distance between the limiting strip 213 and the extrusion plate 210, thus enabling the fixing of compressors of different lengths.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
