Description

Technical Field

[0001] The invention relates to the technical field of ball screw processing, in particular to a straightening machine for ball screw processing. Background Art

[0002] Ball screws are the most commonly used transmission elements in tool machinery and precision machinery. Their main function is to convert rotational motion into linear motion, or to convert torque into axial repetitive force. They also have the characteristics of high precision, reversibility and high efficiency. Due to their very small friction resistance, ball screws are widely used in various industrial equipment and precision instruments. During the ball screw processing process, a straightening machine is required to straighten and correct the screw.

[0003] For example, patent publication number CN221581545U discloses a straightening device for ball screw production. This patent uses a sliding plate to slide into a pressure plate, so that a wedge is engaged in a slot to limit the transmission shaft and roller. This makes it easier and faster to disassemble and assemble the roller than with bolts, saving time when disassembling the roller, thereby effectively improving the efficiency of disassembly and assembly, thereby reducing the time cost of maintenance and improving production efficiency. However, in actual use, this type of straightening machine is not convenient for performing local straightening within a specific range of the screw during straightening because the support part below the screw is fixed, resulting in a relatively general overall straightening effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a straightening machine for ball screw processing is proposed. Summary of the Invention

[0011] Furthermore, the support assembly also includes a fixing frame, a locking screw and a locking plate.

[0012] Furthermore, fixed tubes are arranged on both sides of the upper part of the electric cylinder, and brushes are arranged on the top of the fixed tubes, and the brushes are in a cross shape.

[0013] Furthermore, the dust collection assembly includes a second double-toothed shaft, a reversing gear, a gear ring and a synchronous sleeve.

One end of the adjustment sleeve is slidably connected to the support rod, the electromagnet is fixed on the top of the support rod, and the buffer pad is provided at the bottom of the electromagnet.

[0016] The present invention provides a straightening machine for ball screw processing, which has the following beneficial effects: 1. Before straightening the ball screw, the present invention can start the dual-axis motor according to demand, so that it drives the first dual-tooth shaft to roll on the rack through the active gear, so that the slide seat can slide on the slide rail, thereby changing the position of the support platform when supporting, so that the local range of the ball screw can be straightened according to demand, and the straightening range is wider. At the same time, the micrometer is integrated on the electric cylinder, so that the position of the micrometer can also be controlled by adjusting the component, so that multiple positions of the screw can be detected, thereby improving the detection effect. In the detection process, the brush will fit with the ball screw, so its surface can be cleaned in advance to avoid impurities adhering to the surface and affecting the detection accuracy of the micrometer, reducing interference, and the brush is cross-shaped, which is convenient for cleaning the surface of the screw during horizontal movement or when the rotating seat drives the screw to rotate, which is beneficial to improving the cleaning effect.

[0017] 2. During the detection process of the present invention, when the electric cylinder drives the support platform to move downward, the limit frame will be pulled by the connecting rod to slide along the guide frame, and the detection plate can be driven to move to the bottom of the ball screw through the guide rod. At this time, since the end of the detection plate is inclined, it has a certain guiding effect, which meets the needs of detecting screws within a certain size and improves the use range of the equipment. Afterwards, the compression spring will push the detection plate to make it close to the screw. Therefore, when the screw is bent, the detection plate will move synchronously, and the micrometer can observe the bending condition of the screw by measuring the position of the detection plate. When the electric cylinder drives the support platform to move up to support the ball screw, the connecting rod will push the limit frame, so that the detection plate can be moved away from the bottom of the ball screw, automatically avoiding it, so as to facilitate subsequent press-to-straighten operations.

[0018] 3. Before straightening, the present invention first drives the support platform to move up by the electric cylinder so that the floating needle contacts the bottom of the ball screw. At this time, under the action of the reset spring, the curvature formed by the tops of multiple floating needles can fit the curvature of the bottom of the screw, and the degree of fit is further improved by the deformation performance of the rubber pad. Then, the locking screw is rotated to make the locking plate squeeze the floating needle. At this time, since the surface of the floating needle is relatively rough, the friction between the multiple floating needles can be increased under extrusion, and the position of the floating needle after movement can be locked to ensure that the floating needle will not slide under subsequent extrusion, thereby enhancing the stability during straightening. Therefore, during subsequent straightening, since the top of the floating needle is relatively close to the bottom of the ball screw, the pressure can be evenly distributed, reducing the local pressure loss on the ball screw and avoiding secondary damage to the ball screw during straightening.

[0019] 4. In the present invention, when the electric cylinder moves to make the brush clean the bottom of the ball screw, the dual-axis motor will also drive the second dual-tooth shaft to rotate. At this time, due to the adsorption of the permanent magnet by the electromagnet, the adjustment sleeve drives the synchronous sleeve to move downward, and the gear ring will mesh with the reversing gear. The second dual-tooth shaft will drive the fan shaft to rotate through the reversing gear, gear ring, and synchronous sleeve, so that a negative pressure is formed on the upper part of the fixed box, thereby adsorbing and collecting the dust swept by the brush through the through hole at the top of the fixed tube, which is more environmentally friendly. At the same time, the impurities in the airflow are filtered by the filter plate and discharged from the bottom. At this time, the airflow is blown to the first dual-tooth shaft under the action of the guide plate. The shaft and rack can be cleaned by jet cleaning to avoid impurities adhering to their surface and aggravating wear, which is beneficial to extending the service life of the equipment. When the direction of the current is changed to make the dual-axis motor reverse, the current direction of the electromagnet is also changed. At this time, the magnetic poles of the electromagnet are reversed, and the repulsive force will push the permanent magnet to drive the adjustment sleeve upward, thereby separating the ring gear from the reversing gear. At this time, the synchronous sleeve will directly engage with the second double-toothed shaft, so that when the dual-axis motor rotates forward or reverse, the rotation direction of the fan shaft will not be changed, so that it can only perform suction operations on the top of the fixed box to maintain the normal operation of the dust collection component.

The dust collection assembly 12 also includes a support rod 1208, an electromagnet 1209 and a buffer pad 1210. One end of the adjustment sleeve 1206 is slidably connected to the support rod 1208, and the top of the support rod 1208 is fixed with an electromagnet 1209, and the bottom of the electromagnet 1209 is provided with a buffer pad 1210. The specific operation is as follows: before straightening, the electric cylinder 603 is first used to drive the support platform 604 to move upward, and the floating needle 802 will contact the bottom of the ball screw. At this time, under the action of the return spring 801, the arc formed on the top of the multiple floating needles 802 can fit with the arc of the bottom of the screw, and the deformation performance of the rubber pad 803 is used to further improve the fit. Then, the locking screw 805 is rotated to make the locking plate 806 squeeze the floating needle 802. At this time, since the surface of the floating needle 802 is relatively rough, the friction between the multiple floating needles 802 can be increased under extrusion, and the position of the floating needle 802 after moving can be locked to ensure that the floating needle 802 will not slide under subsequent extrusion, thereby To enhance the stability during straightening, the top of the floating needle 802 fits closely with the bottom of the ball screw, which can evenly distribute the pressure and reduce the local pressure loss on the ball screw. In the subsequent detection process, the brush 10 fits closely with the ball screw, so its surface can be cleaned in advance to avoid impurities adhering to the surface and affecting the detection accuracy of the micrometer and reduce interference. At the same time, the brush 10 is in a cross shape, which is convenient for cleaning the surface of the screw during horizontal movement or when the rotating seat 5 drives the screw to rotate, which is beneficial to improve the cleaning effect. During this process, the dual-axis motor 606 also drives the second double-toothed shaft 1201 to rotate. At this time, due to the electromagnet 12 09 adsorbs the permanent magnet 1207, so that the adjusting sleeve 1206 drives the synchronous sleeve 1204 to move downward, and the ring gear 1203 will mesh with the reversing gear 1202. The second double-toothed shaft 1201 will drive the fan shaft 1205 to rotate through the reversing gear 1202, the ring gear 1203, and the synchronous sleeve 1204, so that a negative pressure is formed on the upper part of the fixed box 605, thereby adsorbing and collecting the dust swept by the brush 10 through the through hole on the top of the fixed tube 9, which is more environmentally friendly. At the same time, the impurities in the airflow are filtered by the filter plate 11 and discharged from the bottom. At this time, under the action of the guide plate 13, the airflow is blown to the first double-toothed shaft 608 and the rack 609, which can be sprayed Air cleaning can prevent impurities from adhering to its surface and aggravating wear, which is beneficial to extending the service life of the equipment. Subsequently, when the current direction is changed to reverse the dual-axis motor 606, the current direction of the electromagnet 1209 is also changed. At this time, the magnetic poles of the electromagnet 1209 are reversed, and the repulsive force will push the permanent magnet 1207, causing it to drive the adjustment sleeve 1206 to move upward, thereby separating the ring gear 1203 from the reversing gear 1202. At this time, the synchronous sleeve 1204 will directly engage with the second double-toothed shaft 1201, so that when the dual-axis motor 606 rotates forward or reverse, the rotation direction of the fan shaft 1205 will not be changed, so that it can only perform suction operations on the top of the fixed box 605.

[0025] In summary, when using this straightening machine for ball screw processing, first, the two ends of the ball screw are placed in the rotating seats 5 on both sides. Secondly, the electric cylinder 603 drives the support platform 604 to move upward, so that the floating needle 802 contacts the bottom of the ball screw. At this time, under the action of the reset spring 801, the curvature formed on the top of multiple floating needles 802 can fit the curvature of the bottom of the screw, and the deformation performance of the rubber pad 803 is used to further improve the fit. Then, the locking screw 805 is rotated to make the locking plate 806 squeeze the floating needle 802. At this time, since the surface of the floating needle 802 is relatively rough, the friction between the multiple floating needles 802 can be increased under extrusion, and the position of the floating needle 802 after movement can be locked to ensure that the floating needle 802 will not slide under subsequent extrusion. Therefore, during the subsequent straightening, since the top of the floating needle 802 is relatively close to the bottom of the ball screw, the pressure can be evenly distributed, reducing the local pressure loss on the ball screw. Then, when the electric cylinder 603 drives the support platform 604 to move downward, it will pull the limit frame 706 through the connecting rod 708 to make it slide along the guide frame 707, and the guide rod 704 can drive the detection plate 703 to move to the bottom of the ball screw. At this time, since the end of the detection plate 703 is inclined, it has a certain guiding effect, which meets the requirements of detecting the screw within a certain size. After that, the compression spring 705 will push the detection plate 703 to make it close to the screw. Therefore, when the bent part of the screw rotates, the detection plate 703 will move synchronously, and the micrometer 701 will measure the position change of the detection plate 703 The bending condition of the screw rod can be observed, and then the dual-axis motor 606 is started to drive the first dual-tooth shaft 608 to roll on the rack 609 through the active gear 607, so that the slide 602 slides on the slide rail 601, and the position during detection can be controlled to detect multiple positions of the screw rod. In the detection process, the brush 10 will fit with the ball screw, and its surface can be cleaned in advance. In the process of movement, the dual-axis motor 606 will also drive the second dual-tooth shaft 1201 to rotate. At this time, due to the electromagnet 1209 adsorbing the permanent magnet 1207, the adjusting sleeve 1206 drives the synchronous sleeve 1204 to move downward, and the gear ring 1203 will mesh with the reversing gear 1202, and the second dual-tooth shaft 1201 will pass through the reversing gear 1 202, the ring gear 1203, and the synchronous sleeve 1204 drive the blade shaft 1205 to rotate, which can form a negative pressure on the upper part of the fixed box 605, thereby adsorbing and collecting the dust swept by the brush 10 through the through hole on the top of the fixed tube 9. At the same time, the impurities in the airflow are filtered by the filter plate 11 and discharged from the bottom. At this time, under the action of the guide plate 13, the airflow is blown to the first double-toothed shaft 608 and the rack 609, which can be jet-cleaned. Subsequently, when the current direction is changed to reverse the dual-axis motor 606, the current direction of the electromagnet 1209 is also changed. At this time, the magnetic poles of the electromagnet 1209 are reversed, and the repulsive force will push the permanent magnet 1207, causing it to drive the adjusting sleeve 1206 to move upward, thereby separating the ring gear 1203 from the reversing gear 1202.At this time, the synchronous sleeve 1204 will directly engage with the second double-toothed shaft 1201, so that when the dual-axis motor 606 rotates forward or reverse, the rotation direction of the fan shaft 1205 will not be changed. Finally, when the electric cylinder 603 drives the support platform 604 to move upward to support the ball screw, the connecting rod 708 will push the limit frame 706, so that the detection plate 703 can be moved away from the bottom of the ball screw and automatically avoid it. In this process, the position of the support platform 604 can also be changed by adjusting the component 6, so that the local range of the ball screw can be straightened according to needs. Afterwards, the electric linear module 2 controls the pressure head 4 to the specified position, and the hydraulic cylinder 3 drives the pressure head 4 to move downward to press the ball screw for straightening.
