Description

Technical Field

[0001] This utility model relates to the field of torque testing machine technology, and in particular to a torque testing machine for automobile chassis components. Background Technology

[0002] A torque tester, also called a torque meter or torque gauge, is a precision instrument used to measure various rotational or torsional forces. This utility model, disclosed in CN222353400U, belongs to the field of automotive parts torque testing technology, specifically a torque testing mechanism for automotive parts. It includes a fixed frame, which is rectangular in shape. Two parallel rotating rods are rotatably mounted on the inner wall of the fixed frame. Each rotating rod has external threads with opposite directions on its left and right sides. The external threads on both sides are screwed together to a clamping plate. In this utility model, the bolt to be tested is placed between the two clamping plates. A hand crank drives a drive rod to rotate, clamping the bolt. Then, a handle slowly lowers the mounting cylinder, allowing the nut to be inserted into the slot. The torque testing motor is then activated, driving the mounting cylinder to rotate and tighten the nut. When the torque sensor detects the torque on the output shaft of the torque testing motor, the data is quantified and displayed on the screen, thus providing information on the bolt's torque and enabling testing of bolts of different models. In practical applications, it has some shortcomings. The use of the clamping plate limits the types of test parts that the device can handle, and it cannot guarantee that the parts will be firmly clamped during use. Parts may shift, which may reduce the accuracy of the measurement. In addition, the clamping plate cannot be adjusted individually, which makes it impossible to connect with the sleeve when clamping irregularly shaped parts, thus making testing impossible. Improvements are needed. Utility Model Content

[0004] This utility model adopts the following technical solution: a torque testing machine for automotive chassis components, including a mounting plate, a data display screen fixedly mounted on the side of the mounting plate, a cavity opened inside the mounting plate, a bracket fixedly mounted on the upper surface of the mounting plate, a chuck rotatably connected to the upper surface of the cavity, a first fixing block fixedly mounted on the lower surface of the cavity, a first connecting rod rotatably connected inside the first fixing block, a scissor arm rotatably connected to the surface of the first connecting rod, a second connecting rod rotatably connected to the upper end of the scissor arm, a second fixing block rotatably connected to the surface of the second connecting rod, a rotating plate fixedly mounted on the upper surface of the second fixing block, the rotating plate rotatably connected to the lower surface of the chuck, a jaw threadedly connected to the upper surface of the chuck, a gear disk meshing with the side of the chuck, a movable plate slidably connected inside the bracket, a torque testing motor fixedly mounted on the upper surface of the movable plate, a sleeve fixedly mounted on the output end of the torque testing motor, and a torque sensor electrically connected to the torque testing motor.

[0005] Preferably, a third connecting rod is rotatably connected to the side of the scissor arm, and a lead screw is slidably connected inside the third connecting rod. The lead screw is threaded into the interior of the mounting plate, and a turntable is fixedly mounted at one end of the lead screw. Here, the lead screw passes through the scissor arm, causing the lead screw to drive the scissor arm to move up and down, thereby raising and lowering the chuck and facilitating the adjustment of the chuck jaws.

[0006] Preferably, the gear disk is rotatably connected to the surface of the mounting plate, and a throttle handle is fixedly mounted on the upper surface of the gear disk. This design of the gear disk and throttle handle makes the rotation of the chuck more convenient, allowing users to quickly adjust the chuck position and improving testing efficiency.

[0007] Preferably, the number of jaws is two sets, and the two sets of jaws are centrally symmetrical. Here, the design of two sets of centrally symmetrical jaws can evenly clamp the test component and avoid test errors caused by uneven force.

[0008] Preferably, the surface of the mounting plate is provided with a sliding groove, in which the jaws slide. This groove design allows the jaws to slide flexibly, facilitating adjustment of the clamping position and adapting to test components of different shapes and sizes.

[0009] Preferably, the clamping end of the chuck has a spring groove, and a locking block is slidably connected within the spring groove. There are two sets of locking blocks, symmetrically distributed within the spring groove, and springs are fixedly installed on the opposing surfaces of the two sets of locking blocks. Here, the use of locking blocks and springs allows for easier and faster installation and testing of the required chuck at the clamping end of the chuck, enabling better clamping of the parts during testing.

[0010] Preferably, the clamping end of the jaw is fitted with a chuck, and the surface of the chuck has a groove. The chuck is a V-shaped chuck. Here, the V-shaped chuck and groove design can better adapt to circular or irregularly shaped test parts, enhancing the stability and reliability of clamping.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up an installation plate, cavity, scissor arm, chuck and lead screw structure, the rotation of the lead screw drives the deformation of the scissor arm, which in turn drives the chuck to move up and down, realizing the rapid adjustment of the jaws. This makes it easier and faster to adjust individual jaws when clamping irregularly shaped parts, resulting in more stable and higher accuracy during testing.

[0013] 2. In this utility model, by setting a locking block, spring, locking groove and chuck structure, the groove of the chuck is aligned with the pawl so that the chuck is sleeved on the clamping end of the pawl, and the locking block is inserted into the locking groove, thereby fixing the chuck, making the chuck replacement process faster, and enabling the device to better adapt to different parts.

[0022] Example 1

[0023] Please see Figure 1-2 This utility model provides a technical solution: a torque testing machine for automotive chassis components, including a mounting plate 1, a data display screen 26 fixedly mounted on the side of the mounting plate 1, a cavity 2 formed inside the mounting plate 1, a bracket 3 fixedly mounted on the upper surface of the mounting plate 1, a chuck 4 rotatably connected to the upper surface of the cavity 2, a first fixing block 5 fixedly mounted on the lower surface of the cavity 2, a first connecting rod 6 rotatably connected inside the first fixing block 5, a scissor arm 7 rotatably connected to the surface of the first connecting rod 6, and a second connecting rod rotatably connected to the upper end of the scissor arm 7. 8. A second fixed block 9 is rotatably connected to the surface of the second connecting rod 8. A third connecting rod 16 is rotatably connected to the side of the scissor arm 7. A lead screw 17 is slidably connected inside the third connecting rod 16. The lead screw 17 is threaded into the inside of the mounting plate 1. A turntable 18 is fixedly installed at one end of the lead screw 17. By passing the lead screw 17 through the scissor arm 7, the lead screw 17 drives the scissor arm 7 to move up and down, realizing the lifting and lowering of the chuck 4, which facilitates the adjustment of the jaws 11. A rotating plate 10 is fixedly installed on the upper surface of the second fixed block 9. The rotating plate 10 is rotatably connected to the lower part of the chuck 4. On the surface of the chuck 4, two sets of jaws 11 are threadedly connected to its upper surface. These two sets of jaws 11 are centrally symmetrical, ensuring even clamping of the test component and preventing test errors caused by uneven force. A gear plate 12 is meshed with the side of the chuck 4 and is rotatably connected to the surface of the mounting plate 12. A throttle handle 19 is fixedly mounted on the upper surface of the gear plate 12. The design of the gear plate and the throttle handle 19 makes the rotation of the chuck 4 more convenient, allowing users to quickly adjust the position of the chuck 4 and improve testing efficiency. The bracket 3 has a sliding connection to a movable plate 13. A torque testing motor 14 is fixedly installed on the upper surface of the movable plate 13. A sleeve 15 is fixedly installed at the output end of the torque testing motor 14. A groove 20 is opened on the surface of the mounting plate 1. The claw 11 slides in the groove 20. The groove 20 design allows the claw 11 to slide flexibly, making it easy to adjust the clamping position and adapt to test parts of different shapes and sizes. The torque testing motor 14 is electrically connected to a torque sensor. The torque sensor digitizes the data and displays it on the data display screen 26.

[0024] Example 2

[0025] Please see Figure 4 The clamping end of the jaw 11 has a spring groove 21, and a clamping block 22 is slidably connected in the spring groove 21. There are two sets of clamping blocks 22, which are symmetrically distributed in the spring groove 21. A spring 23 is fixedly installed on the opposite face of the two sets of clamping blocks 22. Using the clamping blocks 22 and springs 23, the clamping end of the jaw 11 can be more conveniently and quickly installed with the chuck 24 required for testing, so that the parts can be better clamped during testing. The clamping end of the jaw 11 is fitted with a chuck 24, and the surface of the chuck 24 has a groove 25. The chuck 24 is a V-shaped chuck 24. The design of the V-shaped chuck 24 and the groove 25 can better adapt to round or irregularly shaped test parts, and enhance the stability and reliability of clamping.

[0026] Working principle: When the equipment is needed, the rotating screw 17 drives the scissor arm 7 to deform, which in turn drives the chuck 4 to rise and fall vertically, adjusting the position of the jaws 11 to meet the testing requirements of different parts. The jaws 11 slide along the threads on the surface of the chuck 4. Rotating the handle 19 causes the gear plate to mesh with the transmission chuck 4, allowing the chuck 4 to rotate horizontally to clamp the parts. When installing the chuck 24, the V-shaped chuck 24 is fitted into the clamping end of the jaws 11. The symmetrical locking blocks 22 in the spring groove 21 are automatically inserted into the locking slots 25 of the chuck 24 by the action of the spring 23, completing the quick fixation. During the test, the torque test motor 14 drives the sleeve 15 on the moving plate 13 to apply torque to the clamped chassis component and record the data. The recorded data is sent to the data display screen 26.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
