Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a non-destructive testing device for compressor housing. Background Technology

[0002] With the rapid development of the manufacturing industry, the production scale of compressors is constantly expanding, and the requirements for production efficiency are increasing. At the same time, consumers are paying more and more attention to product quality and safety, which prompts compressor manufacturers to adopt more efficient and accurate non-destructive testing technologies to ensure that every compressor casing meets strict quality standards.

[0003] A search revealed Chinese patent publication number CN212483408U, which discloses an automatic optical non-destructive testing device. The device includes a base, two sets of machine frames rotatably connected by a fixed rod, suction blocks on the fixed rods adhering to a display device, and a knob that rotates the suction blocks to manually adjust the optical display device. An air-receiving mesh is installed on the front outer wall of the heat sink, and a heat exchange tube is fixedly installed on the front inner wall of the heat sink. Multiple sets of heat dissipation fins are fitted onto the cylindrical surface of the heat exchange tube. A cold air exhaust pipe is fixedly connected to the rear outer wall of the compressor box. In this invention, outside air flows into the air vent through the air-receiving mesh, and the heat exchange tube acts on the outside air. The heat dissipation fins on the heat exchange tube also achieve a cooling effect. The partially cooled air is input into the compressor box for further processing, and the processed cold air is then delivered to the optical device for heat dissipation during high-temperature operation, thus extending the service life of the optical testing equipment. However, for compressor shells with complex or irregular shapes, there may be blind spots in the detection, leading to inaccurate detection. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a non-destructive testing device for compressor housings, which aims to improve the problem in the prior art that there are blind spots in the detection of compressor housings with complex and irregular shapes, resulting in inaccurate detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a non-destructive testing device for a compressor casing, comprising a workbench, a fixing block 1 fixedly connected to the top left side of the workbench, a motor fixedly connected to the top of the outer wall of the fixing block 1, a fixing barrel fixedly connected to the top center of the workbench, a threaded rail fixedly connected to the inner wall of the fixing barrel, a connecting block 1 fixedly connected to the output end of the motor, a push rod 1 fixedly connected to the right side of the connecting block 1, one end of the push rod 1 penetrating through the left side of the fixing barrel and fixedly connected to the connecting barrel, rotating wheels fixedly connected to the front side of the outer wall of the connecting barrel, the outer walls of the two rotating wheels rotatably connected to the threaded rail, detection probes fixedly connected to the front and rear ends of the right side of the outer wall of the connecting barrel, two push rods 2 fixedly connected to the top right side of the workbench, fixing plates fixedly connected to the output ends of the two push rods 2, and a shock-absorbing mechanism provided in the middle of the top right side of the workbench.

[0006] The above technical solution involves connecting a motor output to a connecting block 1. The output end of a push rod 1 on the right side of the connecting block 1 extends through the left side of the fixed barrel and connects to the connecting barrel. The fixed barrel is fixed to the center of the top of the workbench, and its inner wall is provided with a threaded track. The rotating wheel on the front side of the outer wall of the connecting barrel is rotatably connected to the threaded track. When the motor drives the connecting block 1 to rotate, the push rod 1 rotates, causing the connecting barrel to rotate. The rotating wheel rotates along the threaded track, causing the connecting barrel to move axially at the same time. The detection probes at the front and rear ends of the right side of the outer wall of the connecting barrel can perform all-round detection of the compressor housing. The output ends of the two push rods 2 on the top right side of the workbench are connected to a fixed plate to fix the compressor housing so that the detection probes can perform detection.

[0007] As a further description of the above technical solution:

[0008] The shock absorption mechanism includes a slider, the bottom of which is slidably connected to the middle right side of the top of the workbench. Multiple movable wheels are rotatably connected to the front and rear sides of the bottom of the slider. A shock absorber is fixedly connected to the top of the slider. A groove is formed in the middle of the bottom end of the fixed plate. A movable block is slidably connected to the inner wall of the groove. The bottom of the movable block is fixedly connected to the top of the shock absorber. Springs are fixedly connected to the front and rear sides of the right end of the slider. The right ends of the two springs are fixedly connected to the right side of the top of the workbench.

[0009] The above technical solution involves a shock absorber fixed to the top of the slider, a movable block slidably connected to the inner wall of the groove in the middle of the bottom of the fixed plate, and the bottom of the movable block fixed to the top of the shock absorber. When the fixed plate is vibrated, the vibration is transmitted to the shock absorber for buffering through the movable block. Springs are fixedly connected to the front and rear sides of the right end of the slider, and the right end of the spring is fixed to the right side of the top of the worktable. When the slider slides, the spring generates elastic deformation, and its elastic force can further absorb and buffer the vibration energy, thereby reducing the impact of vibration on the fixed plate.

[0010] As a further description of the above technical solution:

[0011] The workbench is fixedly connected to four corners at the bottom, and foot pads are fixedly connected to the bottom of each of the support columns.

[0012] The above technical solution involves fixed support columns at the four corners of the bottom of the workbench. These support columns provide stable support for the workbench, preventing it from shaking or tipping over due to uneven force. Foot pads are fixedly connected to the bottom of multiple support columns. These foot pads increase the friction between the support columns and the placement surface, preventing the workbench from sliding. They also act as shock absorbers, reducing displacement caused by vibration and protecting the workbench and the equipment on it.

[0013] As a further description of the above technical solution:

[0014] A controller is fixedly connected to the top left end of the front side of the workbench, and the controller is electrically connected to the motor.

[0015] The above technical solution allows operators to send command signals to the motor via the controller to regulate the motor's start, stop, and speed parameters, thereby achieving control over the entire equipment's operating status.

[0016] As a further description of the above technical solution:

[0017] A second connecting block is fixedly connected to the top left side of the workbench, and a display screen is fixedly connected to the left side of the outer wall of the second connecting block.

[0018] The above technical solution uses connecting block two to stably support the display screen, which in turn displays the operating status and testing data of the testing equipment, making it convenient for operators to view at any time.

[0019] As a further description of the above technical solution:

[0020] A second fixing block is fixedly connected to the right side of the workbench, and multiple hooks are fixedly connected to the outer wall of the second fixing block.

[0021] The above technical solution provides installation support for the hook by fixing block two. The hook is used to hang testing tools, accessories or store related items, so as to make reasonable use of the surrounding space, facilitate operators to access items and keep the work area clean.

[0022] As a further description of the above technical solution:

[0023] Connecting piece 1 is fixedly connected to the bottom front and rear sides of the connecting block 2, and the right sides of the two connecting pieces 1 are threadedly connected to the top left side of the workbench.

[0024] The above technical solution provides an additional connection point between the connecting block 2 and the worktable through the connecting piece 1. The tightening force generated by the threaded connection makes the connecting block 2 firmly and securely attached to the top left side of the worktable, ensuring the stability of the components on the connecting block 2.

[0025] As a further description of the above technical solution:

[0026] Two connecting pieces are fixedly connected to the bottom left side of the fixed block one, and the bottom of the two connecting pieces two are threadedly connected to the top left side of the workbench.

[0027] The above technical solution involves threaded connection between the bottom of the two connecting pieces 2 and the top left side of the worktable. The axial tension generated by the threaded connection makes the connecting pieces 2 fit tightly against the top of the worktable, thereby firmly fixing the fixing block 1 to the worktable and ensuring the overall stability of the equipment when the motor components on the fixing block 1 are running.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, after the motor is started, it will drive the push rod two and the connecting barrel to rotate and move axially along the threaded track, so that the detection probes at the front and rear ends of the right side of the outer wall of the connecting barrel can scan the compressor shell in all directions. The detection probes can achieve high-level detection without blind spots, effectively reducing the probability of product failure caused by shell defects and improving the safety and reliability of the product.

[0030] 2. In this utility model, the force of the fixed plate sinking is transmitted to the shock absorber through the moving block, and the slider and the moving wheel provide stable support for the shock absorber, so that the shock absorber can give full play to its own shock absorption characteristics. Multiple moving wheels reduce the frictional resistance between the slider and the worktable, so that the shock absorber will not be interfered with by the additional friction force when working.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model provides a non-destructive testing device for a compressor housing, comprising a workbench 1, a fixing block 3 fixedly connected to the top left side of the workbench 1, a motor 4 fixedly connected to the top of the outer wall of the fixing block 3, a fixing barrel 5 fixedly connected to the top center of the workbench 1, a threaded rail 6 fixedly connected to the inner wall of the fixing barrel 5, a connecting block 7 fixedly connected to the output end of the motor 4, a push rod 8 fixedly connected to the right side of the connecting block 7, one end of the push rod 8 passing through the left side of the fixing barrel 5 and fixedly connected to a connecting barrel 22, rotating wheels 9 fixedly connected to the front side of the outer wall of the connecting barrel 22, the outer walls of the two rotating wheels 9 being rotatably connected to the threaded rail 6, detection probes 10 fixedly connected to the front and rear ends of the right side of the outer wall of the connecting barrel 22, two push rods 11 fixedly connected to the top right side of the workbench 1, a fixing plate 12 fixedly connected to the output end of the two push rods 11, and a shock absorption mechanism 2 provided in the middle of the top right side of the workbench 1;

[0040] Specifically, the fixed block 3 on the top left of the workbench 1 supports the motor 4. The motor 4 outputs power to drive the connecting block 7 to rotate, which in turn causes the push rod 8 to drive the connecting barrel 22. The fixed barrel 5 is fixed at the top center of the workbench 1. The threaded track 6 on its inner wall cooperates with the rotating wheel 9 on the outer wall of the connecting barrel 22, so that the connecting barrel 22 moves axially while rotating. The detection probe 10 on the right side of the connecting barrel 22 then performs an all-round detection on the compressor housing. The push rod 11 on the top right of the workbench 1 pushes the fixed plate 12 to move. The fixed plate 12 is used to fix the compressor housing.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The shock absorption mechanism 2 includes a slider 201. The bottom of the slider 201 is slidably connected to the middle right side of the top of the workbench 1. Multiple moving wheels 202 are rotatably connected to the front and rear sides of the bottom of the slider 201. A shock absorber 203 is fixedly connected to the top of the slider 201. A groove 204 is provided in the middle of the bottom of the fixed plate 12. A moving block 205 is slidably connected to the inner wall of the groove 204. The bottom of the moving block 205 is fixedly connected to the top of the shock absorber 203. Springs 206 are fixedly connected to the front and rear sides of the right end of the slider 201. The right ends of the two springs 206 are fixedly connected to the right side of the top of the workbench 1.

[0042] Specifically, the movable wheel 202 at the bottom of the slider 201 allows the slider 201 to slide flexibly in the middle right side of the top of the worktable 1, reducing the friction between it and the worktable 1. The shock absorber 203 at the top of the slider 201 can initially buffer the vibration. The movable block 205 in the groove 204 at the bottom of the fixed plate 12 can slide in the groove 204, transmitting the vibration received by the fixed plate 12 to the shock absorber 203. The shock absorber 203 further processes the vibration, absorbing and buffering the energy. At the same time, the spring 206 on the front and rear sides of the right end of the slider 201, with its right end fixed to the top right side of the worktable 1, causes the spring 206 to undergo elastic deformation when the slider 201 slides, using elastic force to absorb and offset part of the vibration.

[0043] Reference Figure 1 , Figure 2 and Figure 5 Support columns 13 are fixedly connected to the four corners of the bottom of the workbench 1, and foot pads 14 are fixedly connected to the bottom of the multiple support columns 13; a controller 15 is fixedly connected to the top left side of the front side of the workbench 1, and the controller 15 is electrically connected to the motor 4; a connecting block 2 16 is fixedly connected to the top left side of the workbench 1, and a display screen 17 is fixedly connected to the left side of the outer wall of the connecting block 2 16.

[0044] Specifically, the support columns 13 at the four corners of the bottom of the workbench 1 support the entire workbench 1 to ensure its stability. The foot pads 14 at the bottom increase friction and buffer shock absorption to reduce the interference of external vibrations on the equipment. The controller 15 at the top left of the front side of the workbench 1 is electrically connected to the motor 4. The operator can use the controller 15 to precisely control the start, stop and speed of the motor 4 to meet different testing needs. The connecting block 16 at the top left side of the workbench 1 provides stable support for the display screen 17. The display screen 17 can intuitively display the operating parameters and test results of the equipment, allowing the operator to keep track of the equipment's working status in real time.

[0045] Reference Figure 1 , Figure 2 and Figure 4 A fixing block 2 18 is fixedly connected to the right side of the workbench 1, and multiple hooks 19 are fixedly connected to the outer wall of the fixing block 2 18; connecting pieces 1 20 are fixedly connected to the bottom front and rear sides of the connecting block 2 16, and the right sides of the two connecting pieces 1 20 are threadedly connected to the top left side of the workbench 1; two connecting pieces 21 are fixedly connected to the bottom left side of the fixing block 1 3, and the bottom of the two connecting pieces 21 are threadedly connected to the top left side of the workbench 1.

[0046] Specifically, multiple hooks 19 are connected to the fixing block 2 18 on the right side of the workbench 1. The hooks 19 can hang tools and items, making the work area more tidy and orderly. The connecting pieces 1 20 on the front and rear sides of the bottom of the connecting block 2 16 are threaded to the top left side of the workbench 1. The axial tension generated by the threads makes the connecting block 2 16 firmly installed, ensuring the stability of the display screen 17 component on it. The connecting piece 2 21 on the bottom left side of the fixing block 1 3 is also threaded to the top left side of the workbench 1, ensuring that the fixing block 1 3 remains stable when the motor 4 is running, avoiding shaking or displacement.

[0047] Working principle: The compressor housing is fixed by pushing the fixed plate 12 through the push rod 11 on the top right side of the workbench 1. The motor 4 on the top of the fixed block 3 is started. The motor 4 outputs power and drives the connecting block 7 to rotate. The push rod 8 on the right side of the connecting block 7 rotates accordingly. The push rod 8 passes through the left side of the fixed barrel 5 and connects to the connecting barrel 22, so that the connecting barrel 22 also starts to rotate. Since the rotating wheel 9 on the front side of the outer wall of the connecting barrel 22 is rotatably connected to the threaded track 6 on the inner wall of the fixed barrel 5, the connecting barrel 22 will not only rotate but also move axially along the threaded track 6 as the rotating wheel 9 rotates along the threaded track 6. The detection probes 10 at the front and rear ends of the right side of the outer wall of the connecting barrel 22 can perform all-round non-destructive testing on the compressor housing.

[0048] Furthermore, as the compressor housing is placed on the fixed plate 12, the fixed plate 12 sinks due to the weight. At this time, the movable block 205 in the groove 204 at the bottom of the fixed plate 12 moves downward, transmitting the force of the fixed plate 12 sinking to the shock absorber 203 connected to the bottom of the movable block 205. The bottom of the slider 201 slides flexibly on the middle right side of the top of the worktable 1 through multiple movable wheels 202, reducing the frictional resistance between the slider 201 and the worktable 1 and providing stable support for the shock absorber 203. When bearing the force of the fixed plate 12 sinking, the shock absorber 203 exerts its own shock absorption characteristics, slows down the sinking speed of the fixed plate 12, and absorbs some energy, effectively preventing the fixed plate 12 from sinking excessively.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
