Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of detection tooling, and specifically to a high-precision detection tooling for differential clearance values. Background Art
[0002] The differential adjusts the wheel speed difference through the planetary gear system. When the vehicle turns, the outer wheels need to rotate faster than the inner wheels. The differential automatically distributes different speeds to avoid tire skidding or wear. To ensure the driving stability and safety of the vehicle, it needs to be detected with high precision during its production process;
[0003] For example, the utility model patent with the authorization announcement number CN219829835U discloses a detection tooling for differential clearance values. By setting a lifting device, the detection tooling can be jacked up upward during detection using the air pressure effect, and then cooperate with the detection tooling to measure the clearance of the differential. Compared with the existing detection tooling that needs to be lifted to measure the differential clearance, this device has the advantage of being able to conveniently complete the lifting of the detection tooling, without the need to externally connect a lifting device every time of measurement, which is convenient for people to use.
[0004] However, the above technical solution still has some deficiencies. Combining the existing solution and the actual production and processing use, the current detection tooling jacks up the tooling through high-pressure air. Compared with traditional mechanical pushing, the control precision of high-pressure air pushing is lower, especially in the case of high-precision processing. At the same time, when the detection tooling is not in use, the connection with the lifting device does not need to be disassembled, but after a long time of non-use, the detection work will adsorb a large amount of dust, which will affect the accuracy of subsequent detections and other problems. Therefore, we propose a high-precision detection tooling for differential clearance values to solve the problems raised above. Summary of the Invention
[0005] The purpose of the present invention is to provide a high-precision detection tooling for differential clearance values to solve the problems of the high-precision detection tooling for differential clearance values raised in the above background art. Combining the existing solution and the actual production and processing use, the current detection tooling jacks up the tooling through high-pressure air. Compared with traditional mechanical pushing, the control precision of high-pressure air pushing is lower, especially in the case of high-precision processing. At the same time, when the detection tooling is not in use, the connection with the lifting device does not need to be disassembled, but after a long time of non-use, the detection work will adsorb a large amount of dust, which will affect the accuracy of subsequent detections and other problems.
[0006] To achieve the above purpose, the present invention provides the following technical solution: A high-precision detection tooling for differential clearance values, comprising:
[0007] The detection tooling body is arranged in the middle of the fixed frame, and a clamping rod is installed above the detection tooling body, and a clamping groove column is clamped and connected to the upper side of the clamping rod;
[0008] It also includes:
[0009] Dust-proof mechanisms for improving the service life of the detection tooling body are symmetrically arranged on the left and right sides of the outside of the detection tooling body;
[0010] Stable lifting mechanisms for improving the precise position movement of the fixed frame are arranged inside and outside the fixed frame.
[0011] With the above technical solution, by symmetrically arranging dust-proof mechanisms on the left and right sides of the outside of the detection tooling body, effective dust-proofing can be carried out on the detection tooling body when the equipment is not in use. At the same time, stable lifting mechanisms are arranged inside and outside the fixed frame, replacing the high-pressure air pushing method with traditional mechanical transmission, greatly improving the lifting precision of the detection tooling body.
[0012] As a preferred technical solution of the present invention, the dust-proof mechanisms symmetrically arranged on the left and right sides of the outside of the detection tooling body include fixing plates, second electric telescopic rods and protective covers.

Fixing plates are fixedly installed outside the second electric telescopic rods, and a fixed frame is fixedly connected below the fixing plates.
[0013] With the above technical solution, a dust-proof mechanism is formed by combining the fixing plates, second electric telescopic rods and protective covers, which can effectively protect the detection tooling body when it is not in use and effectively avoid the pollution of the detection tooling body by dust.
[0014] As a preferred technical solution of the present invention, the stable lifting mechanisms arranged inside and outside the fixed frame include a moving frame, a connecting disk, rubber pads, springs, a fixed frame, moving blocks, belt pulleys, connecting belts and a first motor. A moving frame is slidably arranged inside the fixed frame, and moving blocks are fixedly installed on the outer side below the moving frame.

The belt pulleys are symmetrically arranged above and below the outside of the fixed frame, and a first motor is connected to the outer side of the middle part below the belt pulleys. A connecting disk is fixedly installed on the upper side of the fixed frame, and rubber pads are installed at equal angles above the connecting disk.

[0016] As a preferred technical solution of the present invention, an installation plate is provided at the rear side of the detection tooling body, and fans are symmetrically installed on the left and right sides of the front side of the installation plate.
[0017] Adopting the above technical solution, by arranging a fan at the rear side of the detection tooling body, the fan can blow away the dust adhered to the outside of the protective cover before the protective cover moves and opens during the use of the device, thereby further preventing the dust adhered to the outside of the protective cover from adhering to the outside of the detection tooling body.
[0018] As a preferred technical solution of the present invention, a sliding rod is fixedly installed on the upper side of the middle part of the installation plate, a lead screw is threadedly connected inside the sliding rod, the upper end of the lead screw is connected to a second motor, and the sliding rod is slidably connected to a limit frame.
[0019] Adopting the above technical solution, since the fan is installed on the front side of the installation plate and the sliding rod is installed above the installation plate, and the lead screw is threadedly connected inside the sliding rod, the second motor connected to the upper end of the lead screw can be turned on, that is, the lead screw will rotate, which can make the sliding rod move up and down inside the limit frame, thereby adjusting the height of the installation plate and the fan, and being able to better blow away the dust adhered to the outside of the protective cover.
[0020] As a preferred technical solution of the present invention, a connecting plate is fixedly installed below the limit frame, and the connecting plate is installed at the rear side of the support frame.
[0021] Adopting the above technical solution, the installation of the connecting plate can support the limit frame, and the support frame can support the connecting plate.
[0022] As a preferred technical solution of the present invention, a first electric telescopic rod is installed in the middle of the support frame, and a connecting rod is installed at the output end of the first electric telescopic rod.
[0023] Adopting the above technical solution, the output end of the first electric telescopic rod is connected to the connecting rod, that is, when the first electric telescopic rod is started, its output end can push the connecting rod.
[0024] As a preferred technical solution of the present invention, a sliding block is slidably arranged outside the connecting rod, a first rotating rod is rotatably connected to the front side outside the sliding block, and the other end of the first rotating rod is rotatably connected to the support frame.
[0025] With the above technical solution, when the connecting rod moves downward, the symmetrically arranged sliding blocks on its outer side will move inward, and drive the first rotating rod connected to the front side to rotate.
[0026] As a preferred technical solution of the present invention, a second rotating rod is rotatably connected to the rear side of the sliding block, and the other end of the second rotating rod is rotatably connected to a moving rod.
[0027] With the above technical solution, since a second rotating rod is also rotatably connected to the rear side of the sliding block, the second rotating rod will also rotate.
[0028] As a preferred technical solution of the present invention, the moving rod is slidably arranged inside the support frame, and a clamping block is fixedly installed below the moving rod, and a clamping rod and a clamping groove column are closely attached to the inner side of the clamping block.
[0029] With the above technical solution, one end of the second rotating rod is connected to the moving rod. That is, when the second rotating rod rotates, it can push the connected moving rod to move inward inside the support frame. At this time, the clamping block installed below the moving rod will also move inward, and its inner side will be closely attached to the outer sides of the clamping rod and the clamping groove column.
[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: for this high-precision detection tooling for differential clearance value, by setting a stable lifting mechanism, the precise control of the position of the detection device can be greatly improved, thereby improving the detection accuracy. At the same time, a dust-proof mechanism is set up to effectively protect the detection device when it is not in use, and can effectively avoid the pollution of the detection device by dust, so that the detection device can maintain the detection accuracy for a long time. In addition, an installation convenience mechanism is set up, which makes the detection device easy to disassemble and install, providing convenience for subsequent maintenance and replacement;
[0031] 1. There are a detection tooling body, a clamping rod, a clamping groove column and a clamping block. By installing the clamping rod above the middle of the detection tooling body, the upper side of the clamping rod can be inserted into the clamping groove column and firmly clamped and connected with the clamping groove column. By placing the detection tooling body above the middle of the protective cover, the symmetrically arranged clamping blocks below the support frame can move inward, and their inner sides can be firmly and closely attached to the clamping rod and the clamping groove column, so as to limit the position of the detection tooling body. Through the clamping of the clamping block, the disassembly and installation of the detection tooling body are facilitated;
[0032] 2. There are a support frame, a moving frame and a fixed frame. The moving frames are symmetrically and fixedly installed on the left and right below the support frame. The moving frames are located inside the fixed frame. The moving blocks are symmetrically installed on the left and right below the outside of the moving frames. The inner sides of the moving blocks are fixedly connected to the connecting belt, and the connecting belt is slidably connected to the pulley. That is, when the pulley rotates, the connecting belt will slide, causing the fixedly connected moving blocks to move up and down, so as to precisely adjust the positions of the moving frame and the support frame. The detection tooling body provided below the middle of the support frame will also be adjusted accordingly;
[0033] 3. There are a fixed plate and a protective cover. The protective covers are symmetrically arranged on the left and right outside the detection tooling body. The protective covers are installed at the output ends of the second electric telescopic rods. That is, when the equipment is not in use, the second electric telescopic rods can be opened, and their output ends can push the connected protective covers to move inward, so that the protective covers symmetrically arranged on the left and right outside the detection tooling body can be fitted together, thereby protecting the detection tooling body by wrapping it;
[0034] 4. There are a mounting plate and a fan. The fan is arranged at the rear of the detection tooling body. The fan is fixedly installed on the front side of the mounting plate. At the same time, the fan can move up and down. When starting the equipment, the fan can be opened to move up and down first to blow away the dust adhered to the outside of the protective cover, effectively avoiding dust from adhering to the outside of the detection tooling body when the protective cover is opened;
[0035] 5. There are a connecting plate, a rubber pad and a spring. The connecting plate is fixedly installed on the upper side of the fixed frame. The rubber pads are installed at equal angles above the connecting plate. The spring is installed above the rubber pad, and the upper side of the spring is fixedly connected to the support frame. The lower side of the support frame is fixedly connected to the moving frame. That is, when the moving frame is lifted, the support frame will move together. At this time, the spring will stretch elastically, making the lifting of the support frame and the moving frame smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0048] Please refer to Figures 1-10 , the present invention provides a technical solution:
[0049] In order to solve the problems existing in the prior art, therefore, in this embodiment, through the following technical solutions, a high-precision detection tooling for the differential clearance value includes:
[0050] The detection tooling body 1, a stability improvement mechanism, is arranged inside and outside the fixed frame 16, enabling the moving frame 12 arranged inside the fixed frame 16 to be adjusted up and down smoothly, thereby precisely controlling the moving position of the detection tooling body 1; a dust-proof mechanism, arranged on the left and right sides outside the detection tooling body 1, can effectively protect the detection tooling body 1 when the equipment is not in use, enabling the detection tooling body 1 to maintain accurate detection for a long time; an installation convenience mechanism, arranged below the inner side of the support frame 6, provides convenience for the disassembly and installation of the detection tooling body 1.
[0051] In the above technical solution, as Figure 2 , Figure 8 and Figure 9 shown, a clamping rod 2 is installed above the middle of the detection tooling body 1. The upper side of the clamping rod 2 can be inserted into the clamping groove column 3 and firmly engaged with the clamping groove column 3. By placing the detection tooling body 1 above the middle of the protective cover 23, at this time, the clamping rod 2 and the clamping groove column 3 will be placed inside the clamping block 4. Then, the first electric telescopic rod 11 installed in the middle of the support frame 6 can be opened. The output end of the first electric telescopic rod 11 can push the fixedly connected connecting rod 8 downward. At this time, the sliding block 9 slidably connected to the outside of the connecting rod 8 will move inward. At the same time, the first rotating rod 7 and the second rotating rod 10 are respectively rotatably connected to the front and back of the outside of the sliding block 9. One end of the first rotating rod 7 is rotatably connected to the support frame 6, and one end of the second rotating rod 10 is rotatably connected to the moving rod 5. That is, when the sliding block 9 moves inward, both the first rotating rod 7 and the second rotating rod 10 will rotate. The second rotating rod 10 will push the connected moving rod 5 to slide inward inside the support frame 6. Since the clamping block 4 is installed at the lower end of the moving rod 5, that is, the clamping block 4 will also move inward and closely fit with the clamping rod 2 and the clamping groove column 3 installed above the detection tooling body 1, thus fixing and clamping the detection tooling body 1.
[0052] Furthermore, in this technical solution, as Figure 1 , Figure 6 and Figure 7As shown, after the detection tooling body 1 is installed below the middle of the support frame 6, moving frames 12 are symmetrically and fixedly installed on the left and right below the support frame 6. The moving frames 12 are arranged inside the fixed frames 16. Moving blocks 17 are fixedly installed on the outer sides below the moving frames 12. The inside of the moving blocks 17 is fixedly installed with a connecting belt 19. The connecting belt 19 is slidably arranged on the outer side of the pulley 18. Then, the first motor 20 connected to the outer side below the pulley 18 can be turned on. That is, the pulley 18 will rotate. At this time, the connecting belt 19 will slide on the outside of the pulley 18. When the connecting belt 19 slides, the connected moving blocks 17 will drive the moving frames 12 to move up and down together. At this time, the support frame 6 will also move, and the detection tooling body 1 will also be lifted accordingly;
[0053] In addition, a connecting plate 13 is installed at the upper end of the fixed frame 16. Rubber pads 14 are installed at equal angles on the upper side of the connecting plate 13. The rubber pads 14 and the support frame 6 are fixedly connected by springs 15 arranged below. That is, when the moving frames 12 and the support frame 6 move upward, the springs 15 will be stretched, making the lifting of the moving frames 12 and the support frame 6 smoother;
[0054] At the same time, in this technical solution, as Figure 2 、 Figure 3 and Figure 4 shown, when the device is not in use, the height of the detection tooling body 1 can be moved to the initial position. A protective cover 23 is arranged inside the fixed frame 16. The protective cover 23 is located on the left and right sides outside the detection tooling body 1. At the same time, the protective cover 23 is installed at the output end of the second electric telescopic rod 22. At the same time, a fixed plate 21 is fixedly connected to the outside of the second electric telescopic rod 22 for limiting. Then, the second electric telescopic rod 22 can be turned on. The output end of the second electric telescopic rod 22 can push the connected protective cover 23 to move inward. That is, the protective covers 23 on the left and right sides outside the detection tooling body 1 can move inward to fit, and the detection tooling body 1 can be wrapped and protected, effectively avoiding dust pollution when the detection tooling body 1 is not in use;
[0055] By arranging a fan 30 at the rear side of the detection tooling body 1, the fan 30 is symmetrically installed on the front side of the mounting plate 29. When the device runs, it is necessary to first open the protective cover 23. The upper part of the mounting plate 29 is fixedly connected to the sliding rod 28, and the inner side of the sliding rod 28 is threadedly connected to the lead screw 25, and its outer side is slidably connected to the limit frame 27. At the same time, the lower part of the limit frame 27 is fixedly connected to the connecting plate 24 fixedly installed at the rear side of the support frame 6. Then, the second motor 26 fixedly connected to the top of the lead screw 25 can be turned on, that is, the lead screw 25 will rotate. At this time, the sliding rod 28 will move up and down, so that the mounting plate 29 and the fan 30 can move together. When starting the device, the fan 30 can be first turned on and moved up and down to blow the dust adhered to the outer side of the protective cover 23, effectively avoiding dust adhering to the outer side of the detection tooling body 1 when the protective cover 23 is opened.
[0056] This is the entire working process of a high-precision detection tooling for differential clearance value. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
