[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-2This utility model provides a technical solution: a VVT torsion testing machine, including a base plate 1, a reducer 2 fixedly mounted on the top of the base plate 1, a servo motor 3 mounted on the output end of the reducer 2, a linear guide rail 6 fixedly mounted on the other side of the top of the base plate 1, a movable seat 7 slidably mounted on the top of the linear guide rail 6, an axial force sensor 5 mounted on the output end of the reducer 2, a rotary disk 4 fixedly mounted on the input end of the axial force sensor 5, a drive assembly 8 for driving the movable seat 7 to move linearly mounted on one side of the linear guide rail 6, a torque sensor 9 fixedly mounted on one side of the movable seat 7, a torque disk 10 fixedly mounted on the input end of the torque sensor 9, and clamps 11 matching the product are respectively mounted on one side of the torque disk 10 and the rotary disk 4.
[0020] The encoder sends a signal to the servo motor 3, which drives the rotating disk 4 to rotate. With the assistance of the torque disk 10, a torque is applied to observe the deformation degree and failure point of the sample under the torque. During the product testing process, a pair of clamps 11 that match the product are used to fix the two ends of the product and the assembly fixture connecting the product. The torque is applied at the angle or stroke set by the encoder. Through the torque sensor 9 on the torque disk 10, the energy is transferred from the servo motor 3 to the product. Then, the torque sensor 9 measures the torque value and torsion angle. At the same time, the axial force value of the product is measured by the axial force sensor 5 set between the rotating disk 4 and the reducer 2. This effectively solves the problem of equipment simplification. While testing the torsion force and angle, the axial force value is also tested. It can be used to detect requirements related to torsion test angle and torque test, such as installation torque test, sliding torque test, etc.
[0021] More preferably, the drive assembly 8 includes a rocker arm 81 rotatably disposed at one end of the linear guide rail 6, a plurality of matching guide blocks 82 slidably disposed on the linear guide rail 6, a lead screw 83 rotatably disposed laterally on the inner side of the linear guide rail 6, and a lead screw sleeve 84 threadedly sleeved on the outer wall of the lead screw 83 and fixedly connected to the two guide blocks 82.
[0022] The upper ends of multiple guide blocks 82 are fixedly connected to the bottom of the movable base 7;
[0023] Rotating the rocker arm 81 clockwise causes the connected lead screw 83 to rotate, causing the lead screw sleeve 84, which is threaded onto the outer wall of the lead screw 83, to rotate. Through multiple guide blocks 82, the lead screw sleeve 84 slides linearly on the linear guide rail 6, causing the connected lead screw sleeve 84 to move linearly to the left side of the lead screw 83. This causes the movable seat 7, which is connected to the multiple guide blocks 82, to move closer to the rotating disk 4, so that the two clamps 11 move closer together to clamp and fix the product.
[0024] More preferably, the inner ends of the linear guide rail 6 are respectively provided with bearings for supporting the rotation of the lead screw 83;
[0025] The linear guide 6 is supported and constrained by bearings installed at both ends of the inner side and sleeved on the outer walls of both ends of the lead screw 83.
[0026] More preferably, the two clamps 11 are respectively fixed to the rotating disk 4 and the torque disk 10 by bolts, and the clamps 11 can be replaced by different product models;
[0027] The two clamps 11 are fixed to the rotating disk 4 and the torque disk 10 by bolts, which facilitates the disassembly and replacement of the clamps 11. The clamps 11 can be replaced according to different product models, which is convenient for clamping and testing different product models.
[0028] Furthermore, the torque sensor 9 itself has a built-in angle sensor, and the torque sensor 9 can simultaneously measure the torque and rotation angle of the product.
[0029] Torque sensor 9 is a torque sensor with a built-in angle sensor, which can measure the rotation angle of the product while testing the product's torque.
[0030] When using this invention: First, calculate the maximum torque of the product itself to ensure the equipment can meet the required force. Select matching fixtures 11 and clamping blocks according to the different models of the product or sample clamping ends. After installing the fixtures 11, turn on the servo motor 3, adjust the knob, and align the two fixtures 11 at the front and rear ends for coaxial alignment. After alignment, install the product. First, insert one end of the product into the torque disk 10 fixture 11 and clamp it. Adjust the drive assembly 8 to move the other end of the assembly fixture connecting the product to the other side of the rotating disk 4 fixture 11, and then move it to the clamping position of the fixture 11 to clamp and fix the product. Press the forward or reverse button on the loading switch to drive the rotating disk 4 to rotate via the servo motor 3, applying torque to the product. The axial force of the product is measured by the axial force sensor 5 located on the rotating disk 4, and the torque and rotation angle of the product are measured by the torque sensor 9 located on the torque disk 10.
