Description

Technical Field

[0001] This invention relates to the field of ball screw processing technology, specifically to a directional positioning and feeding device for ball screw processing. Background Technology

[0002] A ball screw is a device used for linear motion transmission. It typically consists of a screw, a nut, and balls. The ball screw achieves efficient linear motion transmission by the rolling of the balls between the screw and the nut. Ball screws are generally made by rolling steel rods using a rolling mill.

[0003] Currently, the raw materials for ball screw rolling with diameters of 12, 16, 20, 25, 32, 40, 50, and 63 are all manually loaded. Large-diameter raw materials weigh up to 200 kilograms, requiring at least four people to work together to load them. Loading is very difficult, time-consuming, labor-intensive, and dangerous. In addition, at the initial stage of production, center holes need to be drilled at both ends of the ball screw to ensure the positioning and support of the screw in subsequent processing. The drilling process exists independently of the loading process, requiring the transfer of the screw raw material between different processes, which reduces production efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a directional positioning and feeding device for ball screw processing. Summary of the Invention

[0005] The purpose of this invention is to provide a directional positioning and feeding device for ball screw processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a directional positioning and feeding device for ball screw processing, comprising a drive assembly, the drive assembly comprising a cylinder seat, a drive cylinder, a U-shaped plate, an inclined plate, a spring, a drive block, a ramp, and a rack. The drive cylinder is bolted inside the cylinder seat, and the output end of the drive cylinder is connected to the U-shaped plate. Inclined plates are symmetrically fixed at both ends of the U-shaped plate, and the inclined surfaces of the inclined plates at both ends face inwards. A spring is connected to the middle of the U-shaped plate, and the drive block is elastically connected to the end of the spring away from the U-shaped plate. A ramp is formed at the front end of the drive block, and a rack is formed at the top of the middle end of the drive block.

[0007] Furthermore, the drive block slides into the guide groove in the middle of the guide seat, and the guide seat is fixedly connected to four corners with feet. The feet are fixed to the inclined material rack at the end away from the guide seat, and the inclined material rack has bars arranged closely on the inclined surface inside. The two ends of the opening of the inclined material rack are fixed with limit plates, and the relative distance between the limit plates on both sides is less than the length of the bar.

[0008] Furthermore, the inclined end of the inclined material rack is connected to a loading platform, and the loading platform has clearance grooves at both ends of the middle section. The clearance grooves have top holes on both sides of the rear end. Mounting seats are fixedly installed on both sides of the loading platform, and the height of the rear vertical surface of the mounting seat is greater than the diameter of the bar. The mounting seat has a slot at the end of the intersection of the inclined surfaces at both ends.

[0009] Furthermore, the outer side of the mounting base opposite to the opposite side is provided with a drilling assembly. The drilling assembly includes a frame, a through hole, a slide table and a return spring. The bottom middle of the frame is provided with a through hole that passes through the loading platform, and the slide table is slidably installed inside the frame. The slide table is elastically connected to the side wall of the frame near the mounting base through the return spring.

[0010] Furthermore, the drilling assembly also includes a trigger rod, a motor, and a drill rod. The trigger rod is fixedly connected to the bottom of the slide, and the motor is fixedly bolted inside the slide. The drill rod is fixedly connected to the output end of the motor.

[0011] Furthermore, a feeding assembly is slidably fitted inside the top hole. The feeding assembly includes a base and an inclined top. An inclined top is fixedly installed on both sides of the top of the base, and the inclined surface of the top of the inclined top faces the mounting base. The inclined top is slidably fitted with the top holes on both sides of the rear end of the feeding platform.

[0012] Furthermore, the feeding assembly also includes a bearing seat and rollers. The bearing seat is fixed at the middle of the bottom of the base, and the rollers are rotatably installed inside the bearing seat. The outer edge of the rollers abuts against the slope of the front end of the drive block.

[0013] Furthermore, a clamping assembly is fixed to the bottom front end of the mounting base. The clamping assembly includes a back plate, a limiting pin, and a large gear. The back plate is welded and fixed to the bottom end of the clearance groove at the front end of the mounting base, and a limiting pin is fixed to the front side end of the back plate. A large gear is rotatably mounted on one side of the front of the back plate, and the circumferential teeth of the large gear mesh with the rack at the top of the middle end of the drive block for transmission.

[0014] Furthermore, the clamping assembly also includes a pinion and a clamping plate. A pinion is rotatably mounted on the other side of the front of the back plate. The pinion has a smaller diameter than the large gear and its outer edge teeth mesh with each other. The outer edge teeth of the pinion do not contact the top rack of the drive block. The back shafts of the large gear and the pinion are coaxially fixed with clamping plates, and the opposite surfaces of the ends of the clamping plates on both sides are provided with V-shaped grooves that are adapted to the bar stock.

[0015] Furthermore, the guide seat is fixedly installed at one end of the base plate, and a processing table is fixed in the middle of the other end of the base plate. A transplanting module is provided on the back of the other end of the base plate, and the transplanting module is composed of a lead screw module, a lifting cylinder, and a flat clamping cylinder.

[0016] This invention provides a directional positioning and feeding device for ball screw processing, which has the following beneficial effects;

[0017] 1. During the use of this invention, in the first stage of the driving stroke of the driving cylinder, the front slope of the driving block contacts the bottom roller of the bottom support. During the rolling process of the outer edge of the roller on the slope, the bottom support drives the two inclined tops on both sides to be lifted into the top holes on both sides of the rear end of the loading platform. The top of the inclined top of this application has an inclined surface facing the mounting seat, so that the bar material lifted by the inclined top is oriented towards the mounting seat for directional feeding. The bar material falls into the middle slot with the rear inclined surface of the mounting seat to achieve stable placement, thereby realizing the orderly positioning and feeding of the bar material.

[0018] 2. During the use of this invention, in the second stage of the driving stroke of the driving cylinder, a rack is provided at the top center of the driving block. The rack contacts and meshes with the circumferential teeth of the large gear. Furthermore, the large gear meshes with the circumferential teeth of the small gear on the other side of the back plate, driving the clamping plates coaxial with the back of the large gear and the small gear to rotate synchronously in opposite directions. This application provides V-shaped grooves adapted to the bar material on the opposite surfaces at the ends of the clamping plates on both sides, so that the clamping plates on both sides can be folded upward from the clearance grooves opened at the front and rear ends of the middle of the loading platform, and clamp the middle part of the bar material loaded into the slot in the middle of the mounting base. This ensures that the position of the bar material in the mounting bases at both ends is limited and clamped, ensuring the stability of the bar material during subsequent drilling and improving drilling accuracy.

[0019] 3. During the use of this invention, in the third stage of the driving stroke of the driving cylinder, the U-shaped plate continues to move forward against the spring force. The inclined plates at both ends of the U-shaped plate abut against the trigger rod extending from the bottom of the slide table, causing the slide table to slide inside the frame and approach the adjacent mounting seat. The high-speed rotating drill rod, driven by the motor, drills the center holes at both ends of the bar stock. The contact between the inclined plates at both ends of the U-shaped plate and the corresponding trigger rod at the bottom of the slide table enables the slide tables on both sides of the frame, facing away from the mounting seat, to move synchronously towards each other. This achieves synchronous hole drilling at both ends of the bar stock, ensuring consistent hole depths at both ends. Furthermore, the bar stock is securely clamped by the clamping plates on both sides, effectively preventing damage. To ensure the accuracy of the center hole opening, this application denotes the contact between the front slope of the drive block driven by the drive cylinder and the feeding component as the first stage, realizing the positioning and orientation of the bar stock for feeding; the meshing transmission between the rack at the middle end of the drive block and the clamping component as the second stage, realizing the stable clamping of the bar stock; and the transmission cooperation between the inclined plates at both ends of the U-shaped plate and the drilling component as the third stage, realizing the synchronous opening of the center holes at both ends of the bar stock. The driving stroke of the above three stages is driven by a single drive cylinder. By following the steps sequentially, the bar stock feeding, clamping, and opening operations are realized. The streamlined operation not only effectively improves the process integration and shortens the processing time, but also effectively reduces production costs and improves production efficiency.

Detailed Implementation

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] Please see Figures 1 to 7This invention provides a technical solution: a directional positioning and feeding device for ball screw processing, comprising a drive assembly 1. The drive assembly 1 includes a cylinder seat 101, a drive cylinder 102, a U-shaped plate 103, an inclined plate 104, a spring 105, a drive block 106, a ramp 107, and a rack 108. The drive cylinder 102 is bolted inside the cylinder seat 101, and the output end of the drive cylinder 102 is connected to the U-shaped plate 103. The inclined plates 104 are symmetrically fixed at both ends of the U-shaped plate 103, with the inclined surfaces of the two inclined plates 104 facing inwards. The spring 105 is connected to the middle of the U-shaped plate 103, and the drive block 106 is elastically connected to the end of the spring 105 away from the U-shaped plate 103. The drive block 106 has a ramp 107 at its front end and a rack 108 at its top middle end. The drive block 106 slides with the guide groove in the middle of the guide seat 2, and the four corners of the guide seat 2 are fixed. The support is fixedly connected with a support leg 3. The support leg 3 is fixed to the inclined material rack 4 at one end away from the guide seat 2. The inclined material rack 4 has bar stock 5 closely arranged on the inclined surface inside. The two ends of the opening of the inclined material rack 4 are fixed with limit plates 6. The relative distance between the limit plates 6 on both sides is less than the length of the bar stock 5. The top hole 9 is slidably fitted with a feeding assembly 13. The feeding assembly 13 includes a base 1301 and an inclined top 1302. The inclined top 1302 is fixedly installed on both sides of the top of the base 1301. The inclined surface of the top of the inclined top 1302 faces the mounting seat 10. The inclined top 1302 is slidably fitted with the top holes 9 on both sides of the rear end of the feeding platform 7. The feeding assembly 13 also includes a bearing seat 1303 and a roller 1304. The bearing seat 1303 is fixed at the middle of the bottom of the base 1301. The roller 1304 is rotatably installed inside the bearing seat 1303. The outer edge of the roller 1304 abuts against the slope 107 at the front end of the drive block 106.

[0031] The specific operation is as follows: Under the action of gravity, the bar stock 5 is arranged closely together and abuts against each other on the inclined surface inside the inclined rack 4. The lowest bar stock 5 is located at the junction of the bottom end of the inclined surface of the inclined rack 4 and the loading platform 7. The distance between the mounting base 10 and the bottom end of the inclined surface of the inclined rack 4 can only accommodate one bar stock 5. The subsequent bar stock 5 inside the inclined rack 4 is restricted by the limiting baffle 6, ensuring that only one bar stock 5 is pushed in each loading stroke, avoiding accidents caused by loading multiple bars at once. In use, the drive cylinder 102 transmits power to the drive block 106 through the U-shaped plate 103, so that the drive block 106 slides forward under the limiting cooperation with the guide seat 2. In the first stage of the drive stroke of the drive cylinder 102, the front slope 107 of the drive block 106 contacts the bottom roller 1304 of the base support 1301. During the rolling process of the outer edge of the roller 1304 on the slope 107, the base support 1301 drives the two inclined tops 1302 to be lifted in the top holes 9 on both sides of the rear end of the loading platform 7. The top of the inclined top 1302 of this application has an inclined surface facing the mounting base 10, so that the bar 5 lifted by the inclined top 1302 is oriented towards the mounting base 10 for directional feeding. The bar 5 falls into the middle slot 11 through the rear inclined surface of the mounting base 10 for stable placement, realizing the orderly positioning and feeding of the bar 5.

[0032] Please see Figures 3 to 6 The inclined material rack 4 is connected to the loading platform 7 at the end of its inclined surface. The loading platform 7 has clearance grooves 8 at both ends of its middle section, and top holes 9 are provided on both sides of the rear end of the clearance grooves 8. Mounting seats 10 are fixedly installed on both sides of the loading platform 7. The height of the rear vertical surface of the mounting seat 10 is greater than the diameter of the bar stock 5. A slot 11 is provided at the end of the intersection of the inclined surfaces at both ends of the mounting seat 10. Drilling assemblies 12 are provided on the outer sides of the mounting seats 10 away from their opposite surfaces. The drilling assembly 12 includes a frame 1201, a through hole 1202, a slide 1203, and a return spring 1204. The frame 1201... The bottom center of frame 1201 has a through hole 1202 that passes through the loading platform 7, and a slide table 1203 is slidably installed inside the frame 1201. The slide table 1203 is elastically connected to the side wall of the frame 1201 near the mounting base 10 through a return spring 1204. The drilling assembly 12 also includes a trigger rod 1205, a motor 1206 and a drill rod 1207. The trigger rod 1205 is fixedly connected to the bottom of the slide table 1203, and the motor 1206 is fixedly fixed inside the slide table 1203 with bolts. The output end of the motor 1206 is fixedly connected to the drill rod 1207.

[0033] The specific operation is as follows: After the second stage of the drive cylinder 102's stroke, the front end of the drive block 106 reaches the end of the guide groove in the middle of the guide seat 2. While it can no longer move forward, it still maintains the stable clamping of the bar stock 5 by the side clamping plates 1405. In the third stage of the drive cylinder 102's stroke, the U-shaped plate 103 continues to move forward against the elastic force of the spring 105. The inclined plates 104 at both ends of the U-shaped plate 103 abut against the trigger rod 1205 extending from the bottom of the slide table 1203, so that the slide table 1203 slides inside the frame 1201 and approaches the adjacent mounting seat 10. The high-speed rotating drill rod 1207 driven by the motor 1206 drills the center holes at both ends of the bar stock 5. The abutment of the inclined plates 104 at both ends of the U-shaped plate 103 with the corresponding trigger rod 1205 at the bottom of the slide table 1203 achieves the sliding table 1203 in the side frames 1201 facing away from the mounting seat 10. The synchronous movement of the bar stock 5 towards each other enables simultaneous drilling operations at both ends, ensuring consistent drilling depth at both ends. Furthermore, the bar stock 5 is securely clamped by the side clamping plates 1405, effectively guaranteeing the drilling accuracy of the center hole. This application denotes the contact between the front slope 107 of the lower drive block 106 driven by the drive cylinder 102 and the feeding assembly 13 as the first stage, achieving the positioning and orientation of the bar stock 5. The meshing transmission between the rack 108 at the middle end of the drive block 106 and the clamping assembly 14 is denoteed as the second stage, achieving stable clamping of the bar stock 5. The transmission cooperation between the inclined plates 104 at both ends of the U-shaped plate 103 and the drilling assembly 12 is denoteed as the third stage, achieving the synchronous opening of the center holes at both ends of the bar stock 5. The driving stroke of each of the above three stages is driven by a single drive cylinder 102. Following these steps, the feeding, clamping, and drilling operations of the bar stock 5 are sequentially achieved. This streamlined operation not only effectively improves process integration but also shortens processing time.

[0034] Please see Figures 6 to 8A clamping assembly 14 is fixed to the bottom front end of the mounting base 10. The clamping assembly 14 includes a back plate 1401, a limiting pin 1402, and a large gear 1403. The back plate 1401 is welded and fixed to the bottom end of the clearance groove 8 at the front end of the mounting base 10, and the limiting pin 1402 is fixed to the front side end of the back plate 1401. The large gear 1403 is rotatably mounted on one side of the front of the back plate 1401, and the circumferential teeth of the large gear 1403 mesh with the rack 108 at the top of the middle end of the drive block 106. The clamping assembly 14 also includes a small gear 1404 and a clamping plate 1405. The small gear 1404 is rotatably mounted on the other side of the front of the back plate 1401. 4. The diameter of the small gear 1404 is smaller than that of the large gear 1403 and the outer edge teeth mesh with each other. The outer edge teeth of the small gear 1404 do not contact the top rack 108 of the drive block 106. The back shafts of the large gear 1403 and the small gear 1404 are coaxially fixed with clamping plates 1405. The opposite surfaces of the ends of the clamping plates 1405 on both sides are provided with V-shaped grooves that are compatible with the bar stock 5. The guide seat 2 is fixedly installed on one end of the base plate 15. The processing table 16 is fixed in the middle of the other end of the base plate 15. The back of the other end of the base plate 15 is provided with a transfer module 17. The transfer module 17 is composed of a screw module, a lifting cylinder, and a flat clamping cylinder.

[0035] The specific operation is as follows: In the second stage of the drive stroke of the drive cylinder 102, a rack 108 is provided at the top of the middle part of the drive block 106. The rack 108 contacts and meshes with the circumferential teeth of the large gear 1403. Furthermore, the large gear 1403 meshes with the circumferential teeth of the small gear 1404 on the other side of the back plate 1401, thereby driving the clamping plate 1405, which is coaxial with the back of the large gear 1403 and the small gear 1404, to rotate synchronously in opposite directions. In this application, V-shaped grooves adapted to the bar stock 5 are provided on the opposite surfaces at the ends of the clamping plates 1405 on both sides, so that the clamping plates 1405 on both sides can be folded upward by the clearance grooves 8 opened at the front and rear ends of the middle part of the loading table 7, and clamp the middle part of the bar stock 5 in the slot 11 in the middle of the mounting base 10. This ensures that the position of the bar stock 5 in the mounting bases 10 at both ends is limited and clamped, thereby ensuring the stability of the bar stock 5 during the subsequent drilling process and improving the drilling accuracy.

[0036] In summary, when using this ball screw machining orientation and feeding device, the bar stock 5 is tightly arranged and abuts against each other on the inclined surface inside the inclined frame 4 under the action of gravity. The lowest bar stock 5 is located at the junction of the bottom end of the inclined surface of the inclined frame 4 and the feeding table 7. The distance between the mounting base 10 and the bottom end of the inclined surface of the inclined frame 4 can only accommodate one bar stock 5. The subsequent bar stock 5 located inside the inclined frame 4 is restricted by the limiting baffle 6, ensuring that only one bar stock 5 is pushed in each feeding stroke, avoiding accidents caused by feeding multiple bars at once. During use, the drive cylinder 102 transmits power to the drive block 106 through the U-shaped plate 103, causing the drive block 106 to slide forward under the limiting cooperation with the guide seat 2. In the first stage of the drive cylinder 102, the drive block 106... During the process, the front slope 107 of the drive block 106 contacts the bottom roller 1304 of the base support 1301. As the outer edge of the roller 1304 rolls on the slope 107, the base support 1301 drives the two inclined tops 1302 to be lifted into the top holes 9 on both sides of the rear end of the loading platform 7. The top of the inclined tops 1302 of this application has an inclined surface facing the mounting base 10, so that the bar 5 lifted by the inclined tops 1302 is oriented towards the mounting base 10 for directional feeding. The bar 5 falls into the middle slot 11 from the rear inclined surface of the mounting base 10 for stable placement, realizing the orderly positioning and feeding of the bar 5. In the second stage of the drive stroke of the drive cylinder 102, a rack 108 is provided at the top of the middle part of the drive block 106. The rack 108 and the large gear 1403 The circumferential gear teeth contact and mesh. Further, the large gear 1403 meshes with the circumferential gear 1404 on the other side of the back plate 1401, driving the clamping plates 1405, which are coaxial on the back of the large gear 1403 and the small gear 1404, to rotate synchronously in opposite directions. This application provides V-shaped grooves adapted to the bar stock 5 on the opposite ends of the clamping plates 1405, allowing the clamping plates 1405 to fold upwards from the clearance grooves 8 at both ends of the loading platform 7, clamping the middle of the bar stock 5 in the slot 11 in the middle of the mounting base 10. This limits and clamps the position of the bar stock 5 within the mounting bases 10 at both ends, ensuring the stability of the bar stock 5 during subsequent drilling and improving drilling accuracy. After the second stage of the drive cylinder 102's stroke is completed, this... When the front end of the drive block 106 reaches the end of the guide groove in the middle of the guide seat 2, it cannot continue to move forward, but still maintains the stable clamping of the bar stock 5 by the clamping plates 1405 on both sides. In the third stage of the drive stroke of the drive cylinder 102, the U-shaped plate 103 continues to move forward against the elastic force of the spring 105, and the inclined plates 104 at both ends of the U-shaped plate 103 abut against the trigger rod 1205 extending from the bottom of the slide table 1203, so that the slide table 1203 slides inside the frame 1201 and approaches the adjacent mounting seat 10. The drill rod 1207, driven by the motor 1206, rotates at high speed to drill the center holes at both ends of the bar stock 5. The inclined plates 104 at both ends of the U-shaped plate 103 abut against the trigger rod 1205 at the bottom of the corresponding slide table 1203.The slides 1203 inside the two side frames 1201 opposite to the mounting base 10 move synchronously towards each other, enabling synchronous hole drilling at both ends of the bar stock 5. This ensures that the hole depths at both ends of the bar stock 5 are consistent. Furthermore, the bar stock 5 is securely held by the side clamps 1405, effectively guaranteeing the drilling accuracy of the center hole. In this application, the engagement between the front slope 107 of the lower drive block 106 driven by the drive cylinder 102 and the feeding assembly 13 is designated as the first stage, achieving the positioning and orientation of the bar stock 5. The middle teeth of the drive block 106... The engagement of bar 108 with clamping assembly 14 is designated as the second stage, achieving stable clamping of bar stock 5. The transmission engagement between the inclined plates 104 at both ends of U-shaped plate 103 and drilling assembly 12 is designated as the third stage, achieving synchronous opening of the center holes at both ends of bar stock 5. The driving stroke of the above three stages is driven by a single driving cylinder 102. By sequentially performing the steps of bar stock 5 loading, clamping, and drilling, the streamlined operation not only effectively improves process integration and shortens processing time but also effectively reduces production costs and improves production efficiency.
