Torque tester can be used to detect and calibrate the torque accuracy of assembly tool, to ensure that each bolt reaches the specified tightening torque.

[0003] Torque tester in long-term use, affected by external environment (such as temperature, humidity change) or internal element aging, etc., the measurement accuracy will decrease. Correction device compares with standard torque source, accurately adjusts the measurement error of tester, so that the tester can accurately measure the torque value, meet various high-precision measurement requirements. For example, in the field of aerospace, the torque assembly accuracy of parts is very high, and the torque tester calibrated by the correction device can ensure the reliability of the measurement data and the safety performance of the aircraft.

[0004] But in the prior art, part of the torque tester correction device is difficult to clamp, and the connection between the two is unstable during the measurement and calibration process, which will cause deviation in force transmission when applying torque, so that the measured torque value and the actual standard torque value have a large error, and finally the calibrated torque tester will also bring this error into the measurement link in actual use, affecting the accurate control of product torque, for example, in precision machining, due to measurement error, the assembly of parts is prone to not meet the design requirements, affecting the overall performance and quality of the product, therefore, an environment-friendly parts spraying house is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0005] In order to make up for the above shortcomings, the utility model provides high accuracy automatic correction equipment of torque tester, which aims at improving the problem that part of the torque tester correction device is difficult to clamp in the prior art, which easily affects the overall performance and quality of the product.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A high-precision automatic correction device for torque testing includes a base. A control device is fixedly connected to the top of the base. The inner wall of the control device is provided with a disassembly assembly for removing the cover. A rotating column is rotatably connected to the inner wall of the base. Two transmission plates are rotatably connected to the top of the rotating column. Rotating plates are rotatably connected to both ends of the two transmission plates. A sliding plate is fixedly connected to the top of the other end of the rotating plate. A fixed column is fixedly connected to the top of the sliding plate. An electronic slider is fixedly connected to the bottom of one end of the transmission plate.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a fixing rod that is slidably connected to the inner wall of the control device. Flexible rods are fixedly connected to the outer walls of both ends of the fixing rod. A claw is fixedly connected to the top of the flexible rod, and a flexible plate is fixedly connected to the inner wall of the claw.

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

[0011] The other end of the flexible plate is fixedly connected to the inner wall of another claw, and a pressing rod is slidably connected to the inner wall of the fixing rod;

[0012] As a further description of the above technical solution:

[0013] A return spring is slidably connected inside the fixing rod. One end of the return spring is fixedly connected to the other end of the pressing rod, and the other end of the return spring is fixedly connected to the outer wall of the flexible plate.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the control device is detachably connected to a rear cover, and the outer wall of the claw is detachably connected to the inner wall of the rear cover.

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

[0017] An electronic slide rail is fixedly connected to the inner wall of the base, and the outer wall of the electronic slider is slidably connected to the inner wall of the electronic slide rail.

[0018] As a further description of the above technical solution:

[0019] The top outer wall of the base is provided with a sliding groove, and the outer wall of the fixed column is connected to the inner wall of the sliding groove. The top of the base is fixedly connected with a column, and sliding grooves are provided on both sides of the column.

[0020] As a further description of the above technical solution:

[0021] An electronic slide plate is slidably connected to the inner wall of the column, and the inner wall of the electronic slide plate is slidably connected to the inner wall of the sliding groove. A torque tester is fixedly connected to the outer wall of the electronic slide plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the force component to be tested is placed on the surface of the base. The electronic slider starts to slide linearly on the electronic slide rail. The sliding of the electronic slider drives the two ends of the transmission plate to move outward. The movement of the two ends of the transmission plate causes the rotating plate to change from a vertical position to a horizontal position. At this time, due to the restriction of the slide groove, the fixed column cannot move laterally. Therefore, the fixed column will move towards the middle to achieve the fixed clamping of the test component. This ensures that the force transmission will not deviate during torque detection, thus preventing a large error between the measured torque value and the actual standard torque value.

[0024] 2. In this utility model, pulling the pressing rod causes the return spring to drive the flexible plate to undergo elastic deformation in the direction of the return spring's pull. This causes the two ends of the return spring to contract inward. By utilizing the property of the flexible rod to easily undergo elastic deformation, the claws are driven to contract inward, so that the claws no longer jam the inner wall of the back cover. At this time, the back cover can be removed for quick maintenance of the control device, which greatly improves maintenance efficiency and reduces the production impact caused by maintenance.

[0033] 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.

[0034] Reference Figure 1 , Figure 5 and Figure 6 This utility model provides an embodiment of a high-precision automatic correction device for a torque tester, comprising a base 1, a control device 21 fixedly connected to the top of the base 1, a disassembly assembly for disassembling the cover provided on the inner wall of the control device 21, a rotating column 2 rotatably connected to the inner wall of the base 1, and two transmission plates 3 rotatably connected to the top of the rotating column 2. When torque testing is required on the parts to be tested, the rotating column 2 can serve as a support base for the rotation of the transmission plates 3. Rotating plates 4 are rotatably connected to both ends of the two transmission plates 3, and a sliding plate 7 is fixedly connected to the top of the other end of the rotating plate 4. A fixed column 8 is fixedly connected to the top of the sliding plate 7, and an electronic slider 5 is fixedly connected to the bottom of one end of the transmission plate 3.

[0035] An electronic slide rail 6 is fixedly connected to the inner wall of the base 1, and the outer wall of the electronic slider 5 is slidably connected to the inner wall of the electronic slide rail 6. When a torque test is required on a component, the component is placed on the surface of the base 1. At this time, the electronic slider 5 starts to slide linearly on the electronic slide rail 6. The sliding of the electronic slider 5 drives the two ends of the transmission plate 3 to move outward. The movement of the two ends of the transmission plate 3 causes the rotating plate 4 to change from a vertical position to a horizontal position. The rotation of the rotating plate 4 drives the sliding plate 7 to move, which in turn drives the fixed column 8 to move. At this time, due to the restriction of the slide groove 9, the fixed column 8 cannot move laterally, so the fixed column 8 will move towards the middle to achieve the fixed clamping of the test component.

[0036] This ensures that the force transmission will not deviate during torque testing, preventing a large error between the measured torque value and the actual standard torque value. The top outer wall of the base 1 has a sliding groove 9, and the outer wall of the fixed column 8 is slidably connected to the inner wall of the sliding groove 9. The top of the base 1 is fixedly connected to a column 10, and both sides of the column 10 have sliding grooves 12. The inner wall of the column 10 is slidably connected to an electronic slide plate 11, and the inner wall of the electronic slide plate 11 is slidably connected to the inner wall of the sliding groove 12. The outer wall of the electronic slide plate 11 is fixedly connected to a torque tester 13. The electronic slide plate 11 can slide in the sliding groove 12, thereby driving the torque tester 13 to move, which facilitates torque testing of components in different positions.

[0037] Reference Figures 2 to 6 The disassembly assembly includes a fixing rod 15, which is slidably connected to the inner wall of the control device 21. Flexible rods 18 are fixedly connected to the outer walls of both ends of the fixing rod 15. A claw 19 is fixedly connected to the top of the flexible rod 18. A flexible plate 17 is fixedly connected to the inner wall of the claw 19. The other end of the flexible plate 17 is fixedly connected to the inner wall of another claw 19. A pressing rod 14 is slidably connected to the inner wall of the fixing rod 15. A return spring 16 is slidably connected inside the fixing rod 15. One end of the return spring 16 is fixedly connected to the other end of the pressing rod 14, and the other end of the return spring 16 is fixedly connected to the outer wall of the flexible plate 17. If the inside of the control device 21 is damaged during long-term testing of the components, it will affect the torque test.

[0038] At this point, the back cover 20 needs to be removed to inspect the control device 21. Pulling the pressing rod 14 causes the return spring 16 to elastically deform the flexible plate 17 in the direction of the pull of the return spring 16. This causes the two ends of the return spring 16 to contract inward. By utilizing the elastic deformation property of the flexible rod 18, the claws 19 are driven to contract inward, so that the claws 19 no longer jam the inner wall of the back cover 20. At this point, the back cover 20 can be removed to quickly inspect the control device 21, which greatly improves the inspection efficiency and reduces the production impact caused by the inspection.

[0039] Working principle: When torque testing is required on a component, the component is placed on the surface of the base 1. At this time, the electronic slider 5 starts to slide linearly on the electronic slide rail 6. The sliding of the electronic slider 5 drives the two ends of the transmission plate 3 to move outward. The movement of the two ends of the transmission plate 3 causes the rotating plate 4 to change from a vertical position to a horizontal position. At this time, due to the restriction of the slide groove 9, the fixed column 8 cannot move laterally, so the fixed column 8 will move towards the middle to fix and clamp the test component. This ensures that the force transmission will not deviate during torque testing, thus preventing a large error between the measured torque value and the actual standard torque value.

[0040] If the internal components of the control device 21 are damaged during long-term component testing, it will affect the torque test. In this case, the back cover 20 needs to be removed to inspect the control device 21. Pulling the pressing rod 14 causes the return spring 16 to elastically deform the flexible plate 17 in the direction of the pull of the return spring 16. This causes the two ends of the return spring 16 to contract inward. By utilizing the elastic deformation property of the flexible rod 18, the claws 19 are driven to contract inward, so that the claws 19 no longer jam the inner wall of the back cover 20. At this point, the back cover 20 can be removed to quickly inspect the control device 21, which greatly improves the inspection efficiency and reduces the production impact caused by the inspection.

[0041] 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.
