Description

Technical Field

[0001] This utility model relates to the technical field of straightening and testing devices, and in particular to a straightening and testing device for ball screw production. Background Technology

[0002] A ball screw straightening test device is a tool used to straighten and test ball screws. In order to detect and eliminate the bending of ball screws caused by heat treatment and other processing, and to ensure the performance and normal use of ball screws, the test device usually consists of a dial indicator and a pressure mechanism. The dial indicator is used to test the ball screw, and the pressure mechanism can straighten the bending position of the ball screw.

[0003] After the bending position of the lead screw is detected by the dial indicator using the detection device, pressure is applied to the bent part of the pressure mechanism to straighten it. During the straightening process, the contact points between the two ends of the lead screw and the device may bend, which may lead to over-correction or deviation of the lead screw. Utility Model Content

[0004] The purpose of this invention is to solve the problem that after the bending position of the lead screw is detected by a dial indicator using a testing device, pressure is applied to the bent part of the pressure mechanism for straightening. During the straightening process, the contact points between the two ends of the lead screw and the device may bend, leading to excessive correction or deviation of the lead screw. Therefore, a straightening and testing device for ball screw production is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a straightening and testing device for ball screw production, comprising a machine body, a frame rod fixedly connected to the top of the machine body, a control rod rotatably connected to one side of the frame rod, a pressure rod slidably disposed on the outer surface of the frame rod, an elastic element disposed on the outer surface of the pressure rod, the pressure rod and the control rod being driven by a gear set, rotating the control rod controlling the pressure rod to move downward on the inner wall of the frame rod, a dial indicator disposed on one side of the frame rod, the dial indicator being fixed to one side of the frame rod by a screw and a slider, rotating the screw controlling the slider and the dial indicator to adjust their height position, a support rod fixedly connected to the top of the machine body, two support blocks fixedly connected to the outer surface of the support rod, and a positioning device disposed on the outer surface of the support rod to limit the angle at both ends of the ball screw during straightening.

[0006] The effect achieved by the above components is as follows: When using the testing device, one end of the lead screw is placed on the support block located on the left side of the top of the support rod, and the other end is placed on another support block. Rotating the screw on one side of the dial indicator controls the slider and the dial indicator to move up and down, so that the contact at the bottom of the dial indicator contacts the outer surface of the lead screw. Then, pushing the right end of the lead screw controls the lead screw to move between the top of the two placement blocks and the bottom of the dial indicator contact. When there is a bend in the outer surface of the lead screw, the contact of the dial indicator will be displaced, causing the pointer on the dial indicator to rotate through the gear set inside the dial indicator. The bending condition is judged by the reading of the pointer on the dial indicator. Then, pressing down the control lever rotates, causing the pressure rod to press the elastic element and move downward. The bending position of the lead screw is straightened through the bottom end of the pressure rod. During the straightening process, the lead screw is repeatedly moved to observe the dial indicator reading. After the straightening is completed, the control lever is released, and the elastic element on the outer surface of the pressure rod returns to its original state, which pushes the pressure rod back to its original position.

[0007] Preferably, the positioning device includes two rectangular rods, which are respectively fixedly connected to the two ends of the support rod located on the outside of the support block. Two T-shaped rods are fixedly connected to the top of the rectangular rods, and the two T-shaped rods are respectively located on the outer surface of the rectangular rods. The support rod is located between the two T-shaped rods. A rectangular frame is slidably connected to the outer surface of the T-shaped rods. The inner walls of the rectangular frames slide on both ends of the rectangular rods. A spring is provided on the outer surface of the T-shaped rods. The upper and lower ends of the springs are respectively fixedly connected to the top of the inner wall of the rectangular frame and the top of the rectangular rods. A U-shaped rod is fixedly connected to the bottom of the two rectangular frames.

[0008] The effect achieved by the above components is as follows: by setting up rectangular frames, when straightening a bent lead screw, the U-shaped rod can be pulled down to control the two rectangular frames to move downward on the outer surfaces of the two rectangular rods and the T-shaped rod respectively, and compress the spring. This causes the top of the inner wall of the rectangular frame to press against the two ends of the outer surface of the lead screw, limiting the angle between the two ends of the lead screw and the support rod. After the lead screw is straightened, the U-shaped rod is released, and the spring returns to its original state, which will push the rectangular frame to slide upward on the outer surface of the T-shaped rod back to its original position.

[0009] Preferably, the top end of the T-shaped rod is provided with a retractable rubber sleeve, and the bottom end of the rubber sleeve is fixedly connected to the top end of the rectangular frame.

[0010] The effect achieved by the above components is as follows: when the U-shaped rod is pulled to control the rectangular frame to move downward, the rubber sleeve will be stretched. When the U-shaped rod is released, the spring pushes the rectangular frame to move upward, and the rubber sleeve can buffer the movement of the rectangular frame and prevent the rectangular frame from directly colliding with the top of the T-shaped rod.

[0011] Preferably, T-shaped blocks are fixedly connected to both ends of the rectangular rod, and the inner walls slide on the outer surfaces of the two T-shaped blocks when the rectangular frame moves up and down.

[0012] The effect achieved by the above components is that when controlling the vertical movement of the rectangle, the T-block can further limit the angle between the rectangle and the rectangular rod, so as to avoid the angle of the rectangle from deviating as much as possible and improve the stability of the rectangle when it moves.

[0013] Preferably, a plurality of rubber protrusions are fixedly connected to both sides of the outer surface of the rectangular frame, and the protrusions are arranged linearly on the outer surface of the rectangular frame.

[0014] The effect achieved by the above components is that when the rectangular frame moves, the T-shaped blocks at both ends of the rectangular rod will contact the protrusions on the outer surface of the rectangular frame. The protrusions can further buffer the movement of the rectangular frame and prevent the spring from restoring its original shape and pushing the rectangular frame to reset too quickly.

[0015] Preferably, a rubber pad is fixedly connected to the top of the inner wall of the rectangular frame, and a groove is provided at the bottom of the pad.

[0016] The effect achieved by the above components is that when the rectangular frame is pressed against the outer surface of the lead screw, the contact between the grooved rubber pad and the outer surface of the lead screw can minimize wear on the outer surface of the lead screw and prevent the lead screw from slipping.

[0017] Preferably, a pedal is fixedly connected to one side of the U-shaped rod, and the outer surface of the pedal is provided with several anti-slip strips.

[0018] The effect achieved by the above components is that when using the positioning device, the anti-slip strip on the outer surface of the pedal can be stepped on to more conveniently control the movement of the U-shaped rod and the rectangular frame.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a positioning device, when straightening the lead screw, the two rectangular frames located at both ends of the support rod are moved downward synchronously by pulling the U-shaped rod, pressing the two ends of the lead screw together. This further restricts the position of the lead screw on the outer surface of the support rod and the angle between the lead screw and the support rod, and avoids as much as possible the problem of the two ends of the lead screw tilting or deviating during the straightening process, which would affect the straightening effect.

[0022] Example 1, such as Figure 1-3 As shown, a straightening and testing device for ball screw production includes a body 1. A support rod 3 is fixedly connected to the top of the body 1. A control rod 4 is rotatably connected to one side of the support rod 3. A pressure rod 5 is slidably mounted on the outer surface of the support rod 3. An elastic element is provided on the outer surface of the pressure rod 5. The pressure rod 5 and the control rod 4 are driven by a gear set. Rotating the control rod 4 can control the pressure rod 5 to move downward on the inner wall of the support rod 3. A dial indicator 6 is provided on one side of the support rod 3. The dial indicator 6 is fixed to one side of the support rod 3 by a screw and a slider. Rotating the screw can control the slider and the dial indicator 6 to adjust their height position. A support rod 7 is fixedly connected to the top of the body 1. Two support blocks 8 are fixedly connected to the outer surface of the support rod 7. A positioning device 2 is provided on the outer surface of the support rod 7 to limit the angle at both ends of the screw during straightening. When using the testing device, one end of the screw is placed on the top of the support rod 7. On the left support block 8, the other end is placed on another support block 8. Rotating the screw on one side of the dial indicator 6 controls the slider and the dial indicator 6 to move up and down, so that the contact at the bottom of the dial indicator 6 contacts the outer surface of the lead screw. Then, push the right end of the lead screw to move the lead screw between the top of the two placement blocks and the bottom of the contact of the dial indicator 6. When there is a bend in the outer surface of the lead screw, the contact of the dial indicator 6 will be displaced, causing the pointer on the dial indicator 6 to rotate through the gear set inside the dial indicator 6. The bend condition is judged by the reading of the pointer on the dial indicator 6. Then, press down the control lever 4 to rotate, so that the pressure lever 5 presses the elastic element and moves downward. The bend position of the lead screw is straightened by the bottom end of the pressure lever 5. During the straightening process, the lead screw is moved repeatedly to observe the reading of the dial indicator 6. After the straightening is completed, release the control lever 4. The elastic element on the outer surface of the pressure lever 5 returns to its original state and pushes the pressure lever 5 back to its original position.

[0023] Reference Figure 1-5As shown in this embodiment: the positioning device 2 includes two rectangular rods 21, which are fixedly connected to the two ends of the support rod 7 located outside the support block 8. Two T-shaped rods 22 are fixedly connected to the top of the rectangular rods 21, and the two T-shaped rods 22 are located on the outer surface of the rectangular rods 21. The support rod 7 is located between the two T-shaped rods 22. A rectangular frame 23 is slidably connected to the outer surface of the T-shaped rods 22. The inner walls of the rectangular frame 23 slide on both ends of the rectangular rods 21. A spring 24 is provided on the outer surface of the T-shaped rods 22. The upper and lower ends of the spring 24 are fixedly connected to the top of the inner wall of the rectangular frame 23 and the top of the rectangular rod 21, respectively. A U-shaped rod 28 is fixedly connected to the bottom of the two rectangular frames 23. By setting the rectangular frames 23, the U-shaped rod 28 can be pulled down when straightening the bent lead screw. Two rectangular frames 23 are controlled to move downwards on the outer surfaces of the two rectangular rods 21 and the T-shaped rod 22, respectively, and compress the spring 24. This causes the top of the inner wall of the rectangular frame 23 to press against the two ends of the outer surface of the lead screw, thus limiting the angle between the two ends of the lead screw and the support rod 7. After the lead screw is straightened, the U-shaped rod 28 is released, and the spring 24 returns to its original state, pushing the rectangular frame 23 to slide upwards back to its original position on the outer surface of the T-shaped rod 22. By setting the positioning device 2, when straightening the lead screw, the two rectangular frames 23 located at both ends of the support rod 7 are controlled to move downwards synchronously by pulling the U-shaped rod 28, pressing the two ends of the lead screw together. This further limits the position of the lead screw on the outer surface of the support rod 7 and the angle between it and the support rod 7, and avoids the problem of the two ends of the lead screw tilting or deviating during the straightening process, which would affect the straightening effect.

[0024] Reference Figure 2-5 As shown in this embodiment: a retractable rubber sleeve 25 is provided at the top of the T-shaped rod 22, and the bottom end of the rubber sleeve 25 is fixedly connected to the top of the rectangular frame 23. When the U-shaped rod 28 is pulled to control the rectangular frame 23 to move downward, the rubber sleeve 25 will be stretched. When the U-shaped rod 28 is released, the spring 24 pushes the rectangular frame 23 to move upward. During this process, the rubber sleeve 25 can buffer the movement of the rectangular frame 23 and prevent the rectangular frame 23 from directly colliding with the top of the T-shaped rod 22. T-shaped blocks 26 are fixedly connected to both ends of the rectangular rod 21. When the rectangular frame 23 moves up and down, the inner walls on both sides slide on the outer surfaces of the two T-shaped blocks 26, controlling the rectangular frame 23 to move upward. 3. When moving up and down, the T-block 26 can further limit the angle between the rectangular frame 23 and the rectangular rod 21, so as to avoid the angle of the rectangular frame 23 from deflecting as much as possible and improve the stability of the rectangular frame 23 when moving. Several rubber convex strips 27 are fixedly connected to both sides of the outer surface of the rectangular frame 23. The convex strips 27 are arranged linearly on the outer surface of the rectangular frame 23. When the rectangular frame 23 moves, the T-blocks 26 at both ends of the rectangular rod 21 will contact the convex strips 27 on the outer surface of the rectangular frame 23. The convex strips 27 can further buffer the movement of the rectangular frame 23 and prevent the spring 24 from returning to its original state and pushing the rectangular frame 23 to reset too quickly.

[0025] Reference Figure 2-5 As shown in this embodiment: a rubber pad 211 is fixedly connected to the top of the inner wall of the rectangular frame 23. The bottom end of the pad 211 is provided with a groove. When the rectangular frame 23 presses on the outer surface of the lead screw, the rubber pad 211 with the groove can contact the outer surface of the lead screw to avoid wear on the outer surface of the lead screw as much as possible and prevent the lead screw from slipping. A pedal 29 is fixedly connected to one side of the U-shaped rod 28. Several anti-slip strips 210 are provided on the outer surface of the pedal 29. When using the positioning device 2, the anti-slip strips 210 on the outer surface of the pedal 29 can be stepped on to more conveniently control the movement position of the U-shaped rod 28 and the rectangular frame 23.

[0026] Working principle: When using the testing device, place one end of the lead screw on the support block 8 located on the left side of the top of the support rod 7, and the other end on another support block 8. Rotate the screw on one side of the dial indicator 6 to control the slider and the dial indicator 6 to move up and down, so that the contact at the bottom of the dial indicator 6 contacts the outer surface of the lead screw. Then push the right end of the lead screw to control the lead screw to move between the top of the two placement blocks and the bottom of the contact of the dial indicator 6. When there is a bend in the outer surface of the lead screw, the contact of the dial indicator 6 will be displaced, which will cause the pointer on the dial indicator 6 to rotate through the gear set inside the dial indicator 6. The reading of the pointer on the dial indicator 6 is used to determine the degree of bend. Then pull down the U-shaped rod 28 to control the two rectangular frames 23 to move on both sides. The outer surfaces of the rectangular rod 21 and the T-shaped rod 22 move downwards and compress the spring 24, causing the top of the inner wall of the rectangular frame 23 to press against both ends of the outer surface of the lead screw, thus limiting the angle between the two ends of the lead screw and the support rod 7. The control rod 4 is pressed down to rotate, causing the pressure rod 5 to press against the elastic element and move downwards. The bottom end of the pressure rod 5 is used to straighten the bent position of the lead screw. During the straightening process, the lead screw is moved repeatedly to observe the reading of the dial indicator 6. After the straightening is completed, the control rod 4 is released, and the elastic element on the outer surface of the pressure rod 5 returns to its original state, which will push the pressure rod 5 to rise back to its original position. The U-shaped rod 28 is released, and the spring 24 returns to its original state, which will push the rectangular frame 23 to slide upwards on the outer surface of the T-shaped rod 22 back to its original position.
