Description

Technical Field

[0001] This utility model belongs to the field of ball screw technology, and more specifically, it relates to a special fixing fixture for ball screw processing. Background Technology

[0002] An electric cylinder mainly consists of a motor, a transmission device, and a lead screw. Its working principle is that the torque output by the servo motor is transmitted to the drive mechanism (ball screw) through a transmission device (such as a synchronous belt or gears), thereby achieving high-precision linear motion.

[0003] Ball screws are ideal products for converting rotary motion into linear motion, or vice versa. They are the most commonly used transmission components in machine tools and precision machinery. Their main function is to convert rotary motion into linear motion, or torque into axial reciprocating force, while also possessing the characteristics of high precision, reversibility, and high efficiency.

[0004] Due to the characteristics of ball screws and their widespread use in the mechanical field, mass production of ball screws has begun. During the production of ball screws, it is necessary to drill holes in the ball screws to facilitate subsequent assembly and fixing. When drilling holes, the ball screws need to be fixed. Existing fixtures require manual loading and unloading and tightening, which is very troublesome and slow. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0022] Please see Figures 1 to 3This utility model provides a technical solution: a special fixing fixture for ball screw processing, including a base 1, a mounting frame 2 fixedly connected to the surface of the base 1, a placement groove 3 on the surface of the mounting frame 2, a first support seat 4 and a second support seat 5 fixedly connected to each end of the mounting frame 2, a limiting baffle 6 fixedly connected to the first support seat 4, a support pad 7 on the side of the limiting baffle 6 near the placement groove 3, a cylinder seat fixedly connected to the surface of the second support seat 5, a pushing cylinder 8 facing the placement groove 3 on the cylinder seat, a pushing plate 9 fixedly connected to the piston rod head of the pushing cylinder 8, and a limiting groove 10 adapted to the cross-section of the ball screw on the surface of the pushing plate 9. The mounting bracket 2 has a movable bracket 11 on its surface, and a sliding device 12 is provided between the movable bracket 11 and the mounting bracket 2. The sliding device 12 includes slide rails 1201 located on both sides of the placement groove 3 and fixed to the surface of the mounting bracket 2, and a sliding seat 1202 fixedly connected to the surface of the movable bracket 11. The sliding seat 1202 is slidably connected to the slide rails 1201, and protective stops 1203 are fixedly connected to both ends of the slide rails 1201. The movable bracket 11 has several threaded mounting holes 13 on its surface.

[0023] A clamping device 14 is provided at the center of the movable frame 11. The clamping device 14 includes a vertically downward lifting cylinder 1401 located at the center of the movable frame 11, a clamping plate 1402 located at the piston rod head of the lifting cylinder 1401, a clamping groove 1403 located on the surface of the clamping plate 1402, and an anti-slip pad 1404 provided in the clamping groove 1403.

[0024] The movable frame 11 has extension plates 15 fixedly connected on both sides. The surfaces of the extension plates 15 on both sides are provided with limiting components 16.

[0026] The specific usage and function of this embodiment are as follows: First, the ball screw to be processed can be placed in the placement groove 3. Then, the ball screw is moved to the other end by the push cylinder 8 on the surface of the second support base 5 until both ends of the ball screw are restricted and fixed by the limiting baffle 6 and the push plate 9 respectively. At the same time, the support pad 7 and the limiting groove 10 on the surface can support and protect both ends of the ball screw. After the overall position of the ball screw is fixed, the sliding frame 11 can be flexibly adjusted according to the actual drilling position requirements. After position 11 is adjusted to the clamping position required for drilling, the miniature cylinders 1601 on the two side extension plates 15 work synchronously, driving the limiting pressure plate 1602 at the piston rod head to contact and press against the surface of the mounting bracket 2, making the moving bracket 11 relatively stable and reducing shaking. Then, the lifting cylinder 1401 on the moving bracket 11 drives the piston rod to descend, clamping the ball screw surface through the clamping plate 1402 at the head. The clamping groove 1403 and anti-slip pad 1404 on the surface of the clamping plate 1402 can improve the clamping and fixing effect. In addition, several threaded mounting holes 13 on the surface of the moving bracket 11 are used to install processing devices, which facilitates the direct processing of the ball screw. Several chip removal holes 17 on the surface of the placement groove 3 are used to remove the waste chips generated during the processing of the ball screw. With the help of an external fan, the waste chips can be easily and quickly removed, keeping the interior clean.

[0027] Overall, it achieves the overall positioning and adjustable local precision clamping of the ball screw, which is simple to operate, convenient to use, highly automated, and has good clamping and fixing stability, greatly improving the processing efficiency of ball screws.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
