Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically a high-precision valve body and valve cover quality testing device. Background Technology
[0002] Valve cover quality inspection equipment is a specialized testing device used to systematically evaluate the manufacturing quality of valve covers (key components in valves that cooperate with the valve body to achieve sealing or regulation functions). By integrating multi-dimensional testing technologies, it ensures that the geometric dimensions, material properties, sealing performance, and surface quality of the valve cover meet design specifications and industry standards.
[0003] The existing valve cover inspection equipment has the following significant drawbacks: the fixing of the valve cover during inspection relies heavily on manual labor or a single fixing structure, which not only results in low fixing efficiency and difficulty in quickly adapting to different valve cover specifications to achieve stable and accurate clamping, but also lacks automation. During the inspection process, it is difficult to balance smooth lifting and flexible rotation of the valve cover at multiple angles, which makes it impossible for the flaw detector probe to scan all parts of the valve cover comprehensively and accurately, easily leading to blind spots in the inspection and affecting the comprehensiveness and accuracy of the inspection.
[0004] Therefore, a high-precision valve body and valve cover quality inspection device is needed to solve the problems of existing inspection devices not being able to clamp and fix valve covers of different specifications, and not being able to perform comprehensive inspection of valve covers. Utility Model Content
[0005] The purpose of this invention is to provide a high-precision valve body and valve cover quality inspection device to solve the problems of existing inspection devices being difficult to clamp and fix valve covers of different specifications and difficult to conduct comprehensive inspection of valve covers.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision valve body and valve cover quality inspection device, including an inspection box, a placement pad fixedly connected to the bottom surface inside the inspection box, and a fixing mechanism provided inside the inspection box;
[0007] The fixing mechanism includes a disc, a vertical rod is fixedly connected to the center of the top of the disc, four circumferentially distributed sliding grooves are opened through the top of the disc, a guide rod is fixedly connected inside each sliding groove, a moving block is slidably sleeved on the outer surface of the guide rod, a clamping block is fixedly connected to the bottom surface of the moving block, an anti-slip pad is fixedly connected to one side of the outer wall of the clamping block, and a driving component is provided inside the vertical rod.
[0008] It should be noted in the solution that the drive assembly includes a sliding cavity and four circumferentially distributed movable slots. The sliding cavity is coaxially opened inside the vertical rod. A lead screw is rotatably connected to the center of the bottom end of the sliding cavity. A threaded sleeve is threadedly connected to the outer surface of the lead screw. The four movable slots are all opened on the outer surface of the vertical rod and communicate with the sliding cavity. The outer surface of the threaded sleeve is rotatably connected to the top surface of the four moving blocks through the four movable slots. A forward and reverse motor is installed at the top of the sliding cavity.
[0009] It is worth noting that an electric push rod is installed at the center of the top surface of the detection box. The output end of the electric push rod slides through the inside top surface of the detection box and is coaxially fixedly connected to a mounting shell. A drive motor is installed inside the mounting shell.
[0010] Furthermore, it should be noted that a flaw detector probe is installed on the right side wall inside the testing box, and a display is installed on the outer right side wall of the testing box.
[0011] In a preferred embodiment, each of the movable blocks is slidably engaged with a corresponding groove, and the threaded sleeve is slidably engaged with the sliding cavity.
[0012] In a preferred embodiment, the output end of the forward and reverse motor is coaxially and fixedly connected to the top of the lead screw, and the output end of the drive motor rotates through the bottom of the mounting housing and is coaxially and fixedly connected to the top of the vertical rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The forward and reverse motor drives the lead screw to rotate, causing the threaded sleeve to move. This movement is then pulled by the connecting rod to move the moving blocks. The four moving blocks drive the four clamping blocks to move towards the center of the disc, clamping and fixing the valve cover. This method is applicable to valve covers of different specifications within a certain range. The disc is slowly moved by the electric push rod, and simultaneously driven by the drive motor to rotate the disc slowly. Combined with the flaw detector probe, the valve cover can be subjected to high-precision and comprehensive inspection. This effectively avoids the problems of inspection equipment being unable to clamp and fix valve covers of different specifications and being unable to perform comprehensive inspection of the valve cover.

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.
[0021] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a testing box 1, a placement pad 2 fixedly connected to the bottom surface inside the testing box 1, and a fixing mechanism 3 provided inside the testing box 1;
[0022] The fixing mechanism 3 includes a disc 31, a vertical rod 32 is fixedly connected to the center of the top of the disc 31, and four circularly distributed sliding grooves 33 are opened through the top of the disc 31. A guide rod 34 is fixedly connected inside each sliding groove 33. A moving block 35 is slidably sleeved on the outer surface of the guide rod 34. A clamping block 36 is fixedly connected to the bottom surface of the moving block 35. An anti-slip pad 37 is fixedly connected to one side of the outer wall of the clamping block 36. A drive assembly 38 is provided inside the vertical rod 32.
[0023] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the drive assembly 38 includes a sliding cavity 381 and four circumferentially distributed movable slots 384. The sliding cavity 381 is coaxially opened inside the vertical rod 32. A lead screw 382 is rotatably connected to the center of the bottom end inside the sliding cavity 381. A threaded sleeve 383 is threadedly connected to the outer surface of the lead screw 382. The four movable slots 384 are all opened on the outer surface of the vertical rod 32 and communicate with the sliding cavity 381. The outer surface of the threaded sleeve 383 is rotatably connected to the top surface of the four moving blocks 35 through the four movable slots 384. A forward and reverse motor 386 is installed at the top of the sliding cavity 381.
[0024] Further as Figure 1 and Figure 4As shown, it is worth noting that an electric push rod 4 is installed at the center of the top surface of the test box 1. The output end of the electric push rod 4 slides through the inside top surface of the test box 1 and is coaxially fixedly connected to a mounting shell 5. A drive motor 6 is installed inside the mounting shell 5.
[0025] Further as Figure 1 As shown, it is worth noting that a flaw detector probe 7 is installed on the right side wall inside the inspection box 1, and a display 8 is installed on the right outer wall of the inspection box 1.
[0026] Further as Figure 3 As shown, it is worth noting that each moving block 35 is slidably engaged with the corresponding slide groove 33, which improves the stability of the moving block 35 during movement. The threaded sleeve 383 is slidably engaged with the slide cavity 381, which improves the smoothness of the threaded sleeve 383 during movement.
[0027] Further as Figure 3 and Figure 4 As shown, it is worth noting that the output end of the forward and reverse motor 386 is coaxially and fixedly connected to the top of the lead screw 382, which facilitates the control of the lead screw 382 to rotate in the forward or reverse direction. The output end of the drive motor 6 rotates through the bottom of the mounting shell 5 and is coaxially and fixedly connected to the top of the vertical rod 32, which facilitates the rotation of the vertical rod 32 and the disc 31.
[0028] In summary: When using this testing equipment, first place the valve cover to be tested on the placement pad 2, then turn on the electric actuator 4 to push the disc 31 downwards. When it moves to the appropriate position, turn on the forward and reverse motor 386 to drive the lead screw 382 to rotate clockwise. Under the action of the thread, the lead screw 382 drives the threaded sleeve 383 to move upwards. When the threaded sleeve 383 moves, it pulls the moving blocks 35 through the connecting rod 385. The four moving blocks 35 move simultaneously towards the center of the disc 31, thereby driving the four clamping blocks 36 to clamp the valve cover. The device is fixed in place and can be applied to valve covers of different specifications within a certain range. Then, the electric actuator 4 is turned on to pull the disc 31 and move the valve cover upward slowly. At the same time, the drive motor 6 is turned on to drive the disc 31 and rotate the valve cover slowly. At this time, the flaw detector probe 7 is used to perform quality inspection on the valve cover. The inspection results are observed and recorded by the display 8, realizing high-precision inspection of the valve cover, greatly improving the inspection efficiency of the valve cover, and effectively avoiding the problems that the inspection equipment is not easy to clamp and fix valve covers of different specifications and is not easy to perform comprehensive inspection of the valve cover.
[0029] The forward and reverse motor 386, electric actuator 4, and drive motor 6 can be purchased from the market and are mature technologies in this field, which have been fully disclosed. Therefore, they will not be described again in the specification.
