Description

Technical Field

[0001] This utility model relates to the field of ball screw production, specifically a straightening device for ball screw production. Background Technology

[0002] 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 high precision, reversibility, and high efficiency. Due to their very low frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. However, some ball screw components may bend after production, requiring straightening. Therefore, appropriate straightening devices are needed. China has already authorized... The utility model patent (publication number: CN219703061U) discloses a straightening device for ball screw production. The device uses a hydraulic rod to move a straightening block to straighten the bent parts of the ball screw body. If there are multiple bent points on the ball screw body, the device loosens the ball screw body through a limiting mechanism and a fixing bolt at the top of the connecting pipe. Then, the ball screw body is adjusted, and a rotating mechanism rotates it to align the bent protrusions with the straightening block. It is then fixed again to straighten it once more. This reduces the intensity of manual labor and improves work efficiency.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, when using the existing device, if the length of the ball screw is short and the position of the limiting mechanism in the device is fixed, it is not convenient to effectively limit the ball screw body, which can easily lead to deviations during processing. Moreover, if there are multiple bending points on the ball screw body, it is necessary to release its positioning and then adjust the ball screw body before proceeding to the next straightening process. The operation is cumbersome and not conducive to improving the overall processing efficiency. Therefore, a straightening device for ball screw production is proposed to address the above issues. Utility Model Content

[0004] To address the problem in existing technologies where the ball screw is short and the limiting mechanism is fixed in position, making it difficult to effectively limit the ball screw body and causing deviations during processing, this invention proposes a straightening device for ball screw production.

[0011] Furthermore, a first rubber pad with anti-slip texture is fixed to the side of the clamp away from the electric push rod.

[0012] Furthermore, the pressing mechanism includes a mounting frame, which is shaped like an inverted "U". The top of the mounting frame has a first hollow hole, and a second cylinder is fixed to the top of the mounting frame.

[0025] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a straightening device for ball screw production. (Refer to...) Figures 1-5 A straightening device for ball screw production includes a base 1 and a pressing mechanism 8. A placement block 9 is fixed on the central axis of the base 1. An arc-shaped groove is provided on the top of the placement block 9 to facilitate the placement of the ball screw body to be processed. A pair of fixing clamps 7 are fixed to one end of the base 1.

[0028] A pair of rectangular through slots 10 are provided on the base 1. Two fixing rods 2 are fixed on the two side plates of the base 1. Fixing blocks 3 slide together on the two fixing rods 2. A first cylinder 5 is fixed on one side of the base 1. The moving end of the first cylinder 5 is fixed on the fixing block 3. Connecting blocks 4 are fixed at both ends of the top of the fixing block 3. One end of the connecting block 4 slides on the rectangular through slots 10. A movable clamp 70 is fixed on the top of the connecting block 4. The movable clamp 70 is located on the top surface of the base 1.

[0029] Support blocks 6 are fixed on both sides of the base 1. An electric lead screw linear module 60 is installed on the support block 6. The two ends of the pressing mechanism 8 are fixedly connected to the moving end of the electric lead screw linear module 60.

[0030] The electric lead screw linear module 60 consists of a servo motor, a high-precision ball screw, a linear guide rail, and a slider. The servo motor provides precise power output, the ball screw has the characteristics of high transmission efficiency and high positioning accuracy, and the linear guide rail and slider ensure that the moving end of the electric lead screw linear module 60 can move smoothly and accurately, thereby realizing the precise position adjustment of the pressing mechanism 8 in the vertical direction.

[0031] Reference Figure 1 , Figure 2 and Figure 4 A guide rod 11 is horizontally fixed at one end of the inner wall of the rectangular through groove 10, and the other end of the guide rod 11 is fixed at the other end of the inner wall of the rectangular through groove 10. A through hole 40 is provided on the connecting block 4, and the through hole 40 is clearance-fitted with the guide rod 11.

[0032] The width and depth of the rectangular through groove 10 are not unique and are determined according to the actual design. This ensures that the connecting block 4 can slide stably within it and provides guidance for the movement of the connecting block 4. The guide rod 11, which is horizontally fixed at one end of the inner wall of the rectangular through groove 10, is made of high-strength stainless steel and has a polished surface with extremely low surface roughness. It fits with the through hole 40 on the connecting block 4 with a clearance, further improving the smoothness and accuracy of the sliding of the connecting block 4 and reducing frictional resistance and wear during the movement.

[0033] Reference Figure 1 and Figure 4The fixed clamp 7 and the movable clamp 70 have the same structure. The movable clamp 70 includes an L-shaped plate 700. An electric push rod 701 is fixed on one vertical end of the L-shaped plate 700. A clamping plate 702 is fixedly connected to the moving end of the electric push rod 701. The bottom of the clamping plate 702 is slidably engaged with the horizontal end of the L-shaped plate 700.

[0034] Reference Figure 4 The clamping plate 702 has a first rubber pad fixed on the side away from the electric push rod 701, and the first rubber pad has anti-slip texture.

[0035] The first rubber pad is made of highly elastic and wear-resistant nitrile rubber. Its surface anti-slip texture is specially designed in an interlaced grid pattern, which can increase the friction with the ball screw surface and prevent the screw from slipping during clamping. At the same time, the elasticity of the rubber pad can also effectively protect the screw surface from being pinched.

[0036] Reference Figure 1 and Figure 3 The pressing mechanism 8 includes a mounting frame 80, which is shaped like an inverted "U". The top of the mounting frame 80 has a first hollow hole. A second cylinder 81 is fixed to the top of the mounting frame 80. The moving end of the second cylinder 81 passes through the first hollow hole and is fixed to a pressure plate 83. The top of the mounting frame 80 has two second hollow holes. A vertical rod 82 is fitted into the two second hollow holes with a gap. The bottom of the vertical rod 82 passes through the second hollow hole and is fixed to the top of the pressure plate 83. A second rubber pad is fixed to the bottom of the pressure plate 83. The second rubber pad has anti-slip texture.

[0037] The second rubber pad is made of the same material as the first rubber pad and has the same anti-slip texture on its surface. It can effectively protect the surface of the ball screw during the pressing and straightening process, while increasing the friction with the screw surface to ensure the straightening effect. The vertical rod 82 not only plays a guiding role, but also enhances the stability of the pressure plate 83 during the movement process and prevents the pressure plate 83 from tilting or shaking.

[0038] The width of the two side plates of the mounting bracket 80 is greater than the distance between the two fixed clamps 7 and the movable clamp 70, ensuring that the mounting bracket 80 can move smoothly.

[0039] Working principle: When using this device, first place the ball screw body to be straightened on the placement block 9 of the base 1, so that one end of the screw is within the clamping range of the fixed clamp 7. Start the electric push rod 701 in the fixed clamp 7. The electric push rod 701 pushes the clamping plate 702 to move, firmly clamping one end of the screw.

[0040] Then, according to the length of the ball screw, the first cylinder 5 is activated. The moving end of the first cylinder 5 pushes the fixed block 3 to slide on the fixed rod 2, which drives the movable clamp 70 to move along the length direction of the base 1, so that the movable clamp 70 reaches the appropriate position and firmly clamps the other end of the screw. Through the cooperation of the fixed clamp 7 and the movable clamp 70, the two ends of the ball screw are reliably fixed, ensuring that the screw will not move during the subsequent straightening process.

[0041] Next, based on the degree of bending and straightening requirements of the ball screw, the electric screw linear module 60 is activated, and its moving end drives the pressing mechanism 8 to move to the processing point. Then, the second cylinder 81 is activated, and the moving end of the second cylinder 81 pushes the pressure plate 83 downward. The second rubber pad at the bottom of the pressure plate 83 contacts the surface of the ball screw body and applies a certain pressure for straightening.

[0042] 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.
