Description

Technical Field

[0001] The present application relates to the field of spare parts detection, and in particular to a torque detection tool. Background Art

[0002] Advanced equipment and products are inseparable from high-quality spare parts. Spare parts usually need to be tested for performance before leaving the factory. For spare parts such as gears, torque testing is one of the common testing items. A qualified torque test means that the basic force that the gear can transmit is qualified.

[0003] In the past, torque testing was performed using a torque wrench. The gears were placed in a tooling fixture. The torque wrench had a digital display function. After setting the test torque, workers used the torque wrench to turn the gears. If there was no damage to the gear structure, the torque test was qualified.

[0004] However, when this detection method is applied to large-scale detection, testing a single gear requires repeated actions of picking up, translating, putting down and turning the torque wrench many times, and the torque wrench is heavy, which makes it difficult for workers to complete the torque test quickly, resulting in low efficiency. Summary of the invention

[0005] In order to improve the efficiency of torque detection, the present application provides a torque detection tool.

The torque output mechanism only needs to output torque without additional movement, thereby eliminating the trouble of repeatedly aligning the torque wrench with the test workpiece, thereby greatly improving the efficiency of torque detection on the test workpiece.

[0015] By adopting the above technical solution, the driving member can quickly push the rotating member to rotate. Under the force transmission of the rotating member, the force-applying member provides rotational power to the positioning member.

[0025] Optionally, the torque detection tooling further includes a placement rack, the placement rack is used to support the positioning member, the placement rack is connected to a guide member, the positioning member is provided with a guide groove, and the guide member enters the guide groove.

[0026] By adopting the above technical solution, the guide member enters the guide groove so that the operator can rely on the tactile sense of the hand to determine whether the positioning member is aligned with the gear workpiece, thereby increasing the speed of placing the positioning member and improving the detection efficiency.

[0030] The locking seat is provided with a paving inclined surface on the side where the locking groove is provided, and the paving inclined surface is inclined in a direction away from the locking member along the direction from the first test station to the second test station.

[0031] By adopting the above technical solution, the elastic member provides a thrust for the locking member to engage with the locking groove. When the moving mechanism moves from the first test station to the second test station, with the cooperation of the giving way inclined surface, the locking member first retracts and then pops out. The locking member can be automatically engaged with the locking groove without manually pulling the locking member, thereby improving the detection efficiency. After the detection is completed, the locking member can be manually pulled to make the locking member leave the locking groove.

[0033] By adopting the above technical solution, the rotating handle can drive the first eccentric wheel to rotate through the transmission cooperation of the rotating transmission member and the first eccentric wheel. Due to the eccentric setting of the first eccentric wheel, the rotation of the first eccentric wheel drives the lifting member to slide, and the lifting member can lift the test workpiece on the supporting member and disengage from the limiting member, thereby facilitating the removal of the test workpiece on the mobile mechanism after the inspection is completed, thereby improving the inspection efficiency.

[0036] Optionally, the handle is fixedly connected to a second eccentric wheel, and the second eccentric wheel is used to press against the slide rail.

[0037] By adopting the above technical solution, the handle controls the lifting of the lifting piece, and at the same time, the second eccentric wheel is pressed against the slide rail to fix the movable seat, thereby reducing the slippage of the movable seat when taking out the test workpiece, and locking the handle to maintain the stability of the lifting piece when it is lifted.

[0038] In summary, this application has the following beneficial effects:

[0039] 1.

DETAILED DESCRIPTION

[0052] The following is combined with Figure 1-9 This application is described in further detail.

[0053] The present application can perform torque detection on a variety of test workpieces, and one of the test workpieces is disclosed below, such as Figure 1 As shown, the test workpiece is specifically a gear workpiece 1 , the outer wall of the gear workpiece 1 is provided with gear teeth along the circumferential direction, and the gear workpiece 1 is provided with a plurality of bosses 11 .

[0054] Example 1

[0055] Embodiment 1 of the present application discloses a torque detection tool. Figure 2 As shown, a torque detection tool includes a moving mechanism 4, a positioning member 5 and a torque output mechanism 3. The torque detection tool also includes a base 2 and a support frame 21. A first test station 23 and a second test station 24 are provided on the base 2. The moving mechanism 4 is provided on the base 2, the torque output mechanism 3 is provided on the support frame 21, the first test station 23 is provided on the base 2 and is located outside the support frame 21, and the second test station 24 is provided on the base 2 and is located at the bottom of the support frame 21.

[0056] During detection, the gear workpiece 1 is placed on the moving mechanism 4, the positioning member 5 covers and connects to the gear workpiece 1, and the torque output mechanism 3 applies torque to the positioning member 5 to make the positioning member 5 rotate relative to the moving mechanism 4, thereby detecting the gear workpiece 1.

[0057] The torque output mechanism 3 includes a driving member 31, a rotating member 32 and a force-applying member 33. The driving member 31 is fixedly mounted on the top of the support frame 21, and the rotating member 32 is rotatably mounted on the support frame 21. The rotating member 32 is fixedly connected to the output end of the driving member 31. The driving member 31 applies a rotational torque to the rotating member 32 by using compressed fluid as a power source. The driving member 31 can be an oil cylinder and an air cylinder. In this embodiment, it is specifically a rotating air cylinder, so that a predetermined torque can be output to apply rotational power to the rotating member 32.

[0058] The force-applying member 33 is fixedly connected to one end of the rotating member 32 away from the driving member 31. The force-applying member 33 is provided with a force-applying cavity 34, and the force-applying cavity 34 is provided for the positioning member 5 to enter, and the inner walls of the force-applying cavity 34 on both sides can abut against the opposite side walls of the positioning member 5, so as to realize the rapid alignment of the torque output mechanism 3 with the positioning member 5, so that under the rotational power transmitted by the rotating member 32, the force-applying member 33 applies torque to the positioning member 5, so that the positioning member 5 rotates relative to the moving mechanism 4, saving the trouble of the operator repeatedly operating the torque wrench. In this embodiment, the torque output mechanism 3 also includes a manual valve 35, which is used to open and close the operation of the driving member 31, so as to facilitate the operator to control the detection process.

[0059] The moving mechanism 4 includes a moving seat 41, a supporting member 42 and a limiting member 43. The base 2 is provided with a slide rail 22, and the slide rail 22 extends from the first test station 23 to the second test station 24. The moving seat 41 is slidably connected to the slide rail 22 to realize the movement of the moving mechanism 4. The supporting member 42 and the limiting member 43 are used to place the gear workpiece 1.

[0060] A blocking block 27 is fixed to one side of the base 2 close to the first test station 23. The blocking block 27 is used to contact the moving seat 41 and prevent the moving seat 41 from continuing to move. When the blocking block 27 contacts the moving seat 41, the moving seat 41 is in the position of the first test station 23. At this time, the operator can place the gear workpiece 1 on the supporting member 42 and the limiting member 43, or can take the gear workpiece 1 out of the supporting member 42 and the limiting member 43. The first test station 23 is located outside the support frame 21, and has a large operating space, which is convenient for the operator to perform the above-mentioned pick-up and placement operations and improve the detection efficiency.

[0061] The movable seat 41 is fixedly connected with a handle 47, which can be held by an operator. By pushing, the movable seat 41 can be moved from the first test station 23 to the second test station 24. The torque output mechanism 3 performs torque detection on the gear workpiece 1 at the second test station 24, so that the torque output mechanism 3 only needs to output torque without additional movement, thereby eliminating the trouble of repeatedly aligning the torque wrench with the test workpiece, thereby greatly improving the efficiency of torque detection of the test workpiece. After the detection is completed, the movable seat 41 is pulled by the handle 47 to move the movable seat 41 from the second test station 24 to the first test station 23 to replace a different gear workpiece 1 to be tested.

[0062] The supporting member 42 and the limiting member 43 are both fixedly connected to the bearing surface of the movable seat 41. The limiting member 43 is a cylindrical structure. A guide groove 432 is provided in the middle of the bearing surface of the limiting member 43. The cross-section of the notch 432 of the guide groove is circular. The side wall of the limiting member 43 is fixedly connected with a plurality of ridges 431. The plurality of ridges 431 are evenly distributed along the circumferential direction. The ridges 431 extend along the axial direction of the limiting member 43. The gear workpiece 1 is sleeved on the limiting member 43, and the inner wall of the gear workpiece 1 abuts against the ridges 431 to achieve preliminary fixation of the gear workpiece 1.

[0063] The supporting member 42 is a circular frame structure, which surrounds the limiting member 43 and is close to the bottom of the limiting member 43. A plurality of limiting grooves 421 are provided on the bearing surface of the supporting member 42. The limiting grooves 421 are evenly distributed along the circumferential direction. The number of the limiting grooves 421 is the same as the number of the bosses 11 of the gear workpiece 1. When the gear workpiece 1 is sleeved on the limiting member 43, the gear workpiece 1 is placed on the bearing surface of the supporting member 42, and the bosses 11 of the gear workpiece 1 enter the limiting grooves 421, which play a limiting role in the circumferential movement of the gear workpiece 1.

[0064] When detecting the torque, the positioning member 5 is located above the limiting member 43. A positioning groove 51 is provided on one side of the positioning member 5, and the positioning groove 51 can be used for the gear workpiece 1 to enter. A connecting member 54 is fixedly connected to the bottom of the positioning groove 51. The connecting member 54 is cylindrical and extends into the guide groove 432 to guide the rotation direction of the positioning member 5. The side wall of the positioning groove 51 is provided with a plurality of positioning convex strips 52, and the plurality of positioning convex strips 52 form a rack structure meshing with the gear teeth of the gear workpiece 1, thereby fixing the positioning member 5 with the gear workpiece 1. When the positioning member 5 is driven by the force-applying member 33 to rotate, the positioning member 5 transmits the torque to the gear workpiece 1, thereby realizing the torque detection of the gear workpiece 1. Since the boss 11 of the gear workpiece 1 is restricted by the limiting groove 421 and cannot rotate, if the quality of the gear workpiece 1 is qualified, the gear workpiece 1 can withstand the torque applied by the force-applying member 33 during the detection and keep the structure intact. If the quality of the gear workpiece 1 is unqualified, the gear workpiece 1 will crack or even break under the torque applied by the force-applying member 33, thereby judging the quality of the gear workpiece 1.

[0065] The base 2 is fixedly mounted with a placement rack 25, which is used to support the positioning member 5. When the operator replaces the gear workpiece 1 to be inspected in the moving mechanism 4, the positioning member 5 can be temporarily placed on the placement rack 25 to shorten the distance of moving the positioning member 5 and facilitate operation.

[0066] A guide member 26 is fixedly connected to the side of the placement rack 25 close to the moving mechanism 4. The guide member 26 is a block-shaped structure, and a guide groove 53 is opened at a corner of the positioning member 5. When the positioning member 5 is connected to the gear workpiece 1, the guide member 26 enters the guide groove 53. Therefore, when the operator holds the positioning member 5 and moves it, the position of the positioning member 5 relative to the gear workpiece 1 can be felt by feeling the position of the guide member 26 and the guide groove 53. Therefore, the operator can rely on the tactile sense of the hand to determine whether the positioning member 5 is aligned and connected to the gear workpiece 1, thereby completing the connection of the positioning member 5 faster and entering the next detection action faster.

[0067] The torque detection tooling also includes a locking mechanism 6, which includes a locking member 61, which is a rod-shaped structure, and the locking member 61 is inserted and slidably connected to the side wall of the support frame 21. The locking member 61 is sleeved with a locking sleeve 62, and one end of the inner part of the locking sleeve 62 is fixedly connected to the end of the locking member 61 extending from the support frame 21. The second test station 24 is provided with an elastic member 63, which is located inside the locking sleeve 62, and one end of the elastic member 63 is connected to the side wall of the support frame 21. The elastic member 63 is specifically a spring, and the elastic member 63 is sleeved on the locking member 61. The movable seat 41 is fixedly connected with a locking seat 44, and the locking seat 44 is provided with a locking groove 45.

[0068] When the moving mechanism 4 is located at the second testing station 24 , the locking member 61 is engaged with the locking groove 45 , thereby locking the moving mechanism 4 to prevent the gear workpiece 1 from moving when the torque test is performed.

[0069] The end of the locking piece 61 is an arcuate structure, and the locking seat 44 is provided with a yield slope 46 on the side where the locking groove 45 is provided. Along the direction from the first test station 23 to the second test station 24, the yield slope 46 is inclined in the direction away from the locking piece 61. When the movable seat 41 moves from the first test station 23 to the second test station 24, the end of the locking piece collides with the yield slope 46. The inclined surface of the yield slope 46 guides the locking piece to slide, offsetting the elastic force of the elastic piece 63, so that the locking piece 61 will not hinder the movement of the movable seat 41. After the locking piece 61 is aligned with the locking groove 45, the elastic force of the elastic piece 63 causes the locking piece 61 to enter and engage with the locking groove 45, thereby locking the movable seat 41.

[0070] In addition, when the movable seat 41 needs to be unlocked, the operator moves the locking sleeve 62 to drive the locking member 61 to leave the locking groove 45, thereby completing the unlocking.

[0071] The implementation principle of a torque detection tool in Example 1 of the present application is:

[0072] The movable seat 41 is located at the first test station 23, the gear workpiece 1 is placed on the supporting member 42 and sleeved on the limiting member 43, then the positioning member 5 is connected to the gear workpiece 1, and the movable seat 41 is pushed to move to the second test station 24 by the handle 47, and the positioning member 5 enters the force-applying cavity 34 of the force-applying member 33, and at the same time the locking member 61 is engaged with the locking groove 45, and then the manual valve 35 is started to make the force-applying member 33 output torque to the positioning member 5. After the output is completed, the locking sleeve 62 is moved to release the lock of the locking member 61, and the movable seat 41 is pulled to move to the first test station 23. After taking out the positioning member 5, take out the gear workpiece 1, observe whether the gear workpiece 1 is structurally intact, and then replace the gear workpiece 1 to detect the next gear workpiece 1.

[0073] Example 2

[0074] The difference between this embodiment and embodiment 1 is that the handle 47 is rotatably mounted on the moving seat 41, the rotation axis of the handle 47 is parallel to the moving direction of the moving seat 41, and a accommodating chamber 7 is opened inside the moving seat 41, and a main transmission member 71, a rotating transmission member 72 and a first eccentric wheel 73 are rotatably mounted inside the accommodating chamber 7, and the rotation axes of the main transmission member 71, the rotating transmission member 72 and the first eccentric wheel 73 are parallel to each other, the main transmission member 71 is fixedly connected to the handle 47, two rotating transmission members 72 are provided and are respectively located on both sides of the main transmission member 71, and the main transmission member 71 and the rotating transmission member 72 are specifically gears, and the main transmission member 71 is meshed with the rotating transmission members 72 on both sides, so that in the process of rotating the handle 47, the rotating transmission member 72 can be driven to rotate by the main transmission member 71.

[0075] Two first eccentric wheels 73 are provided, and the first eccentric wheels 73 are located above the rotating transmission member 72. The first eccentric wheel 73 includes a wide portion and a narrow portion. The edge of the wide portion of the first eccentric wheel 73 is provided with teeth. The first eccentric wheel 73 is meshed and connected with the rotating transmission member 72 through the teeth, so that the first eccentric wheel 73 can be driven to rotate when the rotating transmission member 72 rotates.

[0076] A lifting member 74 is disposed on the bearing surface of the movable seat 41 and is slidably connected thereto. The lifting member 74 is a rod-shaped structure and is used to abut against the edge of the gear workpiece 1 protruding from the supporting member 42 . The lifting member 74 abuts against the narrow portion of the first eccentric wheel 73 .

[0077] When the gear workpiece 1 needs to be removed from the supporting member 42 and the limiting member 43, since the limiting member 43 is tightly connected to the gear workpiece 1, it is often difficult for the gear workpiece 1 to be removed by hand. Therefore, the operator can rotate the handle 47 to drive the first eccentric wheel 73 to rotate, so that the lifting member 74 slides upward until the lifting member 74 contacts the gear workpiece 1, and drives the lifting member 74 to continue to slide upward, thereby generating a force for the gear workpiece 1 to separate from the supporting member 42, making it easier to remove the gear workpiece 1 and improving the detection efficiency.

[0078] The handle 47 is fixedly connected to a second eccentric wheel 75, and the second eccentric wheel 75 includes a wide portion and a narrow portion. The wide portion of the second eccentric wheel 75 is fixedly connected to the handle 47, and a through hole 76 is provided at the bottom of the movable seat 41, and the through hole 76 is communicated with the accommodating chamber 7. When the handle 47 is rotated, the lifting member 74 is lifted upward, and at the same time, the narrow portion of the second eccentric wheel 75 extends out of the through hole 76 and approaches the slide rail 22, and finally presses against the slide rail 22, thereby locking the movable seat 41 and reducing the slippage of the movable seat 41 when removing the gear workpiece 1. In addition, the friction between the second eccentric wheel 75 and the slide rail 22 is used to prevent the handle 47 from rotating by itself when the operator releases the handle 47, thereby maintaining the lifting effect of the lifting member 74.

[0079] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
