[0019] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.
[0020] This application discloses a ball screw external runout detection device. (Refer to...) Figure 1 It includes a magnetic base 11, a dial indicator 12, and a contact 13. A support rod 2 is fixedly mounted on the magnetic base 11, and the length direction of the support rod 2 is perpendicular to the surface of the magnetic base 11. A sliding ring 21 is slidably mounted on the support rod 2, and a lifting assembly is provided on the support rod 2 to drive the sliding ring 21 to slide along the length direction of the support rod 2. A rotating ring 4 is rotatably mounted on the outer wall of the sliding ring 21, and the rotating ring 4 is coaxially mounted with the sliding ring 21. A rotating rod 41 is fixedly mounted on the side wall of the rotating ring 4, and the rotating rod 41 is arranged in a horizontal direction. A translation block 5 is slidably mounted on the rotating rod 41, and the dial indicator 12 is mounted on the translation block 5. The contact 13 is connected to the probe of the dial indicator 12, and a fixing member is provided on the translation block 5. When using the device to test ball screws on different machine tools, after installing the magnetic base 11 on the machine tool, the lifting assembly can be used to drive the sliding ring 21 to slide up and down on the support rod 2, or drive the rotating ring 4 to rotate between the sliding ring 21, or drive the translation block 5 to slide on the rotating rod 41, and use the fixing component to fix the position of the translation block 5. In this way, the height, distance and angle of the dial indicator 12 on the support rod 2 can be changed, thereby facilitating the contact component 13 to contact and test the outer circle of ball screws of different specifications and models.
[0021] Reference Figure 1The lifting assembly includes a butterfly handle 31, a screw 32, and a connecting block 33. A lifting groove 22 is provided through the side wall of the support rod 2, with its length direction aligned with the length direction of the support rod 2. The screw 32 is rotatably disposed within the lifting groove 22, also with its length direction aligned with the length direction of the support rod 2. The top end of the screw 32 passes through the support rod 2 and connects to the butterfly handle 31. The connecting block 33 is fixedly disposed on the inner wall of the sliding ring 21. The connecting block 33 is slidably disposed within the lifting groove 22, and the connecting block 33 and the lifting groove 22 are mutually adapted to each other. The screw 32 and the connecting block 33 are threadedly connected. When it is necessary to move the sliding ring 21 along the length of the support rod 2, rotate the butterfly handle 31 to drive the screw 32 to rotate in the lifting groove 22. At the same time, the connecting block 33 abuts against the inner wall of the lifting groove 22. The connecting block 33 is guided by the lifting groove 22 and slides on the screw 32, thereby driving the sliding ring 21 to slide on the outer wall of the support rod 2. The operation is convenient and quick, and the cost is low.
[0022] Reference Figure 1 An interference ring 6 is integrally formed on the inner wall of the rotating ring 4. The interference ring 6 is arranged along the circumference of the rotating ring 4 and is coaxial with the rotating ring 4. An interference groove 61 is formed on the outer wall of the sliding ring 21, and the interference ring 6 is slidably disposed in the interference groove 61, with an interference fit between the interference ring 6 and the interference groove 61. When the rotating ring 4 is rotated to change the position of the contact member 13, the interference ring 6 slides in the interference groove 61. Due to the interference fit between the interference ring 6 and the interference groove 61, the friction force can be used to quickly position the rotating ring 4 and the sliding ring 21, which helps to improve the stability of the dial indicator 12 during detection, thereby improving the detection accuracy.
[0023] Reference Figure 1 The fixing component is a clamping bolt 7, which passes through the translation block 5 and is threadedly connected to the translation block 5. After the translation block 5 slides on the rotating rod 41, the clamping bolt 7 is rotated. By using the end of the clamping bolt 7 to abut against the surface of the rotating rod 41, the position of the translation block 5 on the rotating rod 41 can be quickly fixed, which facilitates quick adjustment of the distance between the translation block 5 and the support rod 2.
[0024] Reference Figure 1 A rotating shaft 8 is fixedly installed at the top of the dial indicator 12. The length direction of the rotating shaft 8 is set along the axis of the dial indicator 12. The dial indicator 12 is rotatably connected to the bottom of the translation block 5 through the rotating shaft 8. During testing, the dial indicator 12 can be rotated to facilitate observation of the value of the dial indicator 12 from different directions. An illumination lamp 9 is installed at the bottom of the translation block 5, and the dial indicator 12 is illuminated by the illumination lamp 9 to facilitate reading.
[0025] The implementation principle of the ball screw outer diameter runout detection device in this application embodiment is as follows: When using the device to detect ball screws on different machine tools, after the magnetic base 11 is installed on the machine tool, the butterfly handle 31 can be rotated to drive the screw 32 to rotate, control the connecting block 33 to slide in the lifting groove 22, thereby driving the sliding ring 21 to slide up and down on the support rod 2, or drive the rotating ring 4 to rotate between the sliding ring 21, or drive the translation block 5 to slide on the rotating rod 41, and rotate the clamping bolt 7 to fix the position of the translation block 5. In this way, the height, distance and angle of the dial indicator 12 on the support rod 2 can be changed, thereby facilitating the contact member 13 to contact and detect the outer diameter of ball screws of different specifications and models, and improving the applicability of the detection device.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
