[0023] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.
[0024] like Figures 1 to 6As shown, a component torque testing machine includes a worktable 1, a loading box 2 fixedly mounted on one side of the top of the worktable 1, a slide table 5 slidably mounted on the side of the top of the worktable 1 away from the loading box 2, a lead screw 3 rotatably mounted on the worktable 1 corresponding to the slide table 5, a moving motor 4 mounted on one end of the lead screw 3, a force measuring box 6 fixedly mounted on the slide table 5, and clamps 10 mounted on the opposite side of the force measuring box 6 and the loading box 2, the two clamps 10 being concentrically arranged, lifting components 8 fixedly mounted on both the worktable 1 and the slide table 5, the two lifting components 8 being located between the two clamps 10, a support component 9 fixedly mounted on the top of the lifting components 8, and a drive component 7 installed inside the lifting components 8, both clamps 10 being three-jaw chucks; in use, the worktable 1 first supports the moving motor 4 to drive the lead screw 3 to rotate, pushing the slide table 5 and moving the clamps 10 on the force measuring box 6 towards the loading box 2, adjusting the distance between the two clamps 10 to be slightly greater than the length of the sample shaft 11, and then placing both ends of the sample shaft 11 on the two clamps respectively. On the support assembly 9, the drive assembly 7 drives the lifting assembly 8 to move the sample shafts 11 on the two support assemblies 9 upward, aligning their axes with the center of the clamps 10. After the sample shafts 11 reach the desired position, the openings of the two clamps 10 are adjusted to be larger than the shaft diameter of the sample shafts 11. The sample shafts 11 are then inserted into the clamps 10 on the loading box 2, and the clamps 10 clamp one end of the sample shafts 11. Subsequently, the slide table 5 moves the clamps 10 on the force measuring box 6 toward the sample shafts 11, so that the other end of the sample shafts 11 is inserted into another clamp 10 and clamped. Finally, the installation of the sample shafts 11 is completed. The sample shafts 11 are supported by the support assembly 9 throughout the installation process, which is very convenient and labor-saving. After the sample shafts 11 are installed, the loading box 2 applies force to the sample shafts 11 through the clamps 10, and transmits the force to the force measuring box 6 through another clamp 10 for testing, realizing torque testing. After the test is completed, the clamps 10 can be released under the support of the support assembly 9, making it easy to remove the sample shafts 11.
[0025] like Figures 3 to 6 As shown, the lifting assembly 8 includes a support base 801 fixed to the top of the workbench 1. A lifting frame 802 is slidably mounted on the top of the support base 801. A ruler plate 803 is fixedly mounted on the front bottom of the lifting frame 802. The ruler plate 803 has a scale corresponding to the required rising height of the sample shaft 11 with different shaft diameters. The drive assembly 7, supported by the support base 801, pushes the lifting frame 802 to drive the sample shaft 11 on the support assembly 9 to move upward and adjust its height. During this process, the required rising height of the sample shaft 11 can be calculated, and the ruler plate 803 can measure the rising height of the sample shaft 11. The ruler plate 803 is preset with the required rising height of the sample shaft 11 with different shaft diameters, thereby assisting in the adjustment of the position of the sample shaft 11 and ensuring the accuracy of its position.
[0026] like Figures 3 to 6As shown, the support assembly 9 includes a fixed frame 901 fixed to the top of the lifting frame 802. Two support rollers 902 are rotatably mounted on the fixed frame 901. The fixed frame 901 is V-shaped, and the two support rollers 902 are distributed in a V-shape with an included angle of 90 degrees between them. The two ends of the sample shaft 11 are placed on the two pairs of V-shaped support rollers 902 respectively. The two pairs of V-shaped support rollers 902 can adapt to the support of sample shafts 11 with different shaft diameters. The rolling support of the support rollers 902 facilitates the rolling adjustment of the position of the sample shaft 11 during clamping, which greatly improves the installation efficiency.
[0027] like Figures 3 to 6 As shown, the drive assembly 7 includes a threaded sleeve 701 fixed to the bottom of the lifting frame 802. A screw 702 is rotatably installed in the support base 801 at a position corresponding to the threaded sleeve 701. A transmission gear 703 is fixedly installed at the bottom of the screw 702. A lifting motor 705 is fixedly installed at the bottom of the support base 801. A drive gear 704 that meshes with the transmission gear 703 is installed at the output end of the lifting motor 705. The lifting motor 705 drives the drive gear 704 to mesh with the transmission gear 703, thereby rotating the screw 702. This causes the screw 702 to push the lifting frame 802 upward through the threaded sleeve 701. The lifting frame 802 then drives the sample shaft 11 on the two pairs of support rollers 902 upward through the fixed frame 901, automatically raising the sample shaft 11 to the required position for easy installation of the sample shaft 11.
[0028] The work process is as follows:
[0029] S1: As Figures 1 to 3 As shown, when in use, first make the worktable 1 support the moving motor 4 to drive the lead screw 3 to rotate and push the slide table 5 to move the clamp 10 on the force measuring box 6 towards the loading box 2. Adjust the distance between the two clamps 10 so that it is slightly larger than the length of the sample shaft 11.
[0030] S2: As Figures 3 to 6 As shown, the two ends of the sample shaft 11 are then placed on two pairs of support rollers 902 arranged in a V-shape. At this time, the lifting motor 705 drives the drive gear 704 to mesh with the transmission gear 703 to drive the screw 702 to rotate. The screw 702 pushes the lifting frame 802 upward through the threaded sleeve 701. The lifting frame 802 then drives the sample shaft 11 on the two pairs of support rollers 902 to move upward through the fixed frame 901, so that its axis is aligned with the center of the fixture 10.
[0031] S3: As Figures 3 to 6 As shown, in this process, the required height of the sample shaft 11 can be calculated, and the ruler plate 803 can measure the required height of the sample shaft 11. The ruler plate 803 is preset with the required height of the sample shaft 11 for different shaft diameters, thereby assisting in the adjustment of the position of the sample shaft 11 and ensuring the accuracy of its position.
[0032] S4: As Figures 3 to 6 As shown, after the sample shaft 11 reaches the required position, adjust the openings of the two clamps 10 to be larger than the shaft diameter of the sample shaft 11. At this time, the sample shaft 11 is inserted into the clamp 10 on the loading box 2 under the rolling support of the support roller 902, and the clamp 10 clamps and fixes one end of the sample shaft 11. Then, the slide table 5 drives the clamp 10 on the force measuring box 6 to move towards the sample shaft 11, so that the other end of the sample shaft 11 is inserted into another clamp 10 and clamped and fixed, and finally the installation of the sample shaft 11 is completed.
[0033] S5: As Figures 3 to 6 As shown, after the sample shaft 11 is installed, the loading box 2 applies force to the sample shaft 11 through the clamp 10, and transmits the force to the force measuring box 6 through another clamp 10 for detection, thereby realizing the torque test.
[0034] S6: As Figures 3 to 6 As shown, after the test is completed, the clamp 10 can be released under the support of the support roller 902, which makes it easy to remove the sample shaft 11.
[0035] The loading box 2, the moving motor 4, the force measuring box 6, and the lifting motor 705 in this application are known technologies in this field, therefore their specific structures and working principles are not described in detail.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
