Description

TECHNICAL FIELD

[0001] The present application relates to the ball screw machining technical field, more particularly, to a numerical control tapping equipment for ball screw machining. BACKGROUND

[0002] The ball screw is an ideal product for converting rotary motion into linear motion or vice versa, and is the most commonly used transmission element in tooling machinery and precision machinery. In the ball screw machining process, numerical control tapping equipment is usually used to perform high-precision numerical control drilling and tapping on the center hole, thread bottom hole, mounting hole, positioning thread hole, etc. of the ball screw.

[0003] The existing ball screw tapping usually fixes the ball screw on the machining table first, then drives the motor to work to drive the tapping head to rotate and tap the screw. However, in the existing tapping process, the hole is not drilled in advance, the ball screw is a hard material, and direct tapping machining is difficult to complete, and the workpiece and parts are easily damaged, thereby seriously affecting the machining efficiency.

[0004] In view of the above problems, some solutions are also given in the prior art. For example, the Chinese patent application with publication number CN120921102A discloses a numerical control tapping equipment for ball screw machining. When the device is used, the ball screw is first positioned in the placing seat groove and positioned, the hydraulic cylinder drives the pressing plate to press down and tightly fix the ball screw; then two motors are started to drive the drill and tap to rotate, the first electric cylinder pushes the moving table and motor to move left, the drill drills a hole at one end of the screw, and after completion, the first electric cylinder resets; the second electric cylinder drives the moving table and motor to move backward, so that the tap is aligned with the drilled hole, and then the first electric cylinder pushes the tap to complete tapping, so that drilling can be performed before tapping, and the machining efficiency is effectively improved. However, in actual use, only one screw can be machined, so that drilling and tapping can only be performed separately, and different screws cannot be drilled and tapped at the same time. In addition, the existing technology can only machine one end of the screw, and cannot machine both ends of the screw at the same time, thereby seriously affecting the machining efficiency. SUMMARY

[0005] In view of the problems existing in the prior art, the purpose of the present application is to provide a numerical control tapping equipment for ball screw machining, which can improve the machining efficiency.

[0006] To solve the above problems, the present application adopts the following technical solutions.

[0007] A numerical control tapping equipment for ball screw machining, comprising a machining table, a mounting frame fixedly installed on the machining table, and a machining assembly provided on the mounting frame.

[0008] The machining assembly comprises a mounting plate fixedly installed on a mounting frame, a rotating roller rotatably installed on the mounting plate, a clamping assembly for clamping a screw rod arranged on the rotating roller, a motor fixedly installed on the mounting plate and matched with the rotating roller, electric push rods symmetrically fixedly installed on the mounting frame, a mounting disc fixedly installed on the output end of the electric push rods, a drilling machine and a tapping machine respectively fixedly installed on the mounting disc, and a feeding assembly arranged on the machining table.

[0011] Further, a guide telescopic pipe is jointly installed between the mounting disc and the mounting frame, a horizontal groove is arranged on the machining table, a push block is slidably installed in the horizontal groove, a switch electrically connected with the electric telescopic rod is fixedly installed in the horizontal groove, and an air pipe in communication with the guide telescopic pipe is fixedly installed on the horizontal groove.

[0012] Further, fixed rods are symmetrically slidably installed on the side wall of the mounting block, a third spring is jointly installed between the fixed rods and the mounting block, fixed holes matched with the corresponding fixed rods are arranged on the first clamping plate and the second clamping plate, a push plate matched with the fixed rods is fixedly installed on the mounting plate, and a second inclined groove matched with the push plate is arranged on the fixed rods.

[0013] Further, a guide plate is fixedly installed on the mounting disc, and a second conveying belt is fixedly installed on the machining table and uniformly provided with conveying grooves.

[0014] Further, a linkage groove is arranged on the mounting block, a linkage plate slidably matched with the linkage groove is fixedly installed on the first clamping plate, the side wall of the linkage plate away from the first clamping plate is beveled, a mounting rod is fixedly installed on the guide plate, and a horizontal rod is fixedly installed on the mounting rod.

[0016] Furthermore, a guide block is fixedly installed on the top wall of the feeding plate, and a guide groove is provided on the guide block.

[0017] Furthermore, a pressure relief hole is provided on the horizontal groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This solution uses rotating rollers in conjunction with multiple clamping components to realize the turnover and conveying of lead screws. Drilling machine and tapping machine can simultaneously perform drilling and tapping operations on different lead screws, realizing parallel processing of drilling and tapping processes, avoiding waiting time for single processes, and effectively improving processing efficiency. (2) This solution utilizes an electric push rod to link a pneumatic feeding structure to achieve automatic screw pushing and automatic clamping at the clamping station; after processing, the horizontal bar drives the first clamping plate to move through the linkage plate, automatically unclamping and unloading the material and conveying it to the second conveyor belt. There is no need for personnel to manually load and align the material before processing and spend time unloading it after processing, which reduces labor costs and further improves processing efficiency. (3) By setting a fixed rod, the push plate moves the fixed rod before processing and inserts the fixed rod into the fixed hole, thereby locking the first clamping plate and the second clamping plate, avoiding loose clamping and screw movement during processing, ensuring the coaxiality and dimensional accuracy of drilling and tapping, and improving processing efficiency.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 10 A CNC tapping machine for ball screw processing includes a processing table 101, on which a mounting frame 102 is fixedly installed, and a processing component 2 is provided on the mounting frame 102; The processing assembly 2 includes a mounting plate 201 fixedly mounted on a mounting frame 102. A rotating roller 202 is rotatably mounted on the mounting plate 201. A clamping assembly 3 for clamping a lead screw is provided on the rotating roller 202. A motor 203 cooperating with the rotating roller 202 is fixedly mounted on the mounting plate 201. Electric push rods 204 are symmetrically fixedly mounted on the mounting frame 102. A mounting plate 205 is fixedly mounted on the output end of the electric push rod 204. A drilling machine 206 and a tapping machine 207 are fixedly mounted on the mounting plate 205 respectively. A feeding assembly 4 is provided on the processing table 101.

[0023] In operation, multiple lead screws are first fixed to the rotating roller 202 using the clamping assembly 3. Then, the motor 203 drives the rotating roller 202 to rotate, moving the lead screws towards the drilling machine 206. At this time, the output end of the electric push rod 204 extends and drives the drilling machine 206 to contact the lead screw, thus drilling the lead screw. After drilling, the output end of the electric push rod 204 retracts and drives the drilling machine 206 back to its original position via the mounting plate 205. Then, the motor 203 rotates again and moves the drilled lead screw to the tapping machine 207, while the rotating roller 202 moves the un-drilled lead screw back to the drilling machine 206. At this time, the output end of the electric push rod 204 extends and drives the tapping machine 207 to contact the drilled lead screw via the mounting plate 205, while simultaneously making the drilling machine 206 contact the un-drilled lead screw, thus tapping the lead screw while drilling. Furthermore, during the lead screw processing, the feeding component 4 pushes the unprocessed lead screw to contact the clamping component 3 and automatically feeds it, which improves processing efficiency.

[0024] like Figure 1 , Figure 5 , Figure 8 , Figure 9 , Figure 10 As shown, the clamping assembly 3 includes a mounting block 301 uniformly fixedly mounted on the rotating roller 202. The mounting block 301 has a sliding groove, in which a first clamping plate 302 and a second clamping plate 303 are slidably mounted respectively. A first spring 304 is installed between the first clamping plate 302 and the sliding groove, and a second spring 305 is installed between the second clamping plate 303 and the sliding groove. Both the first clamping plate 302 and the second clamping plate 303 have arc-shaped grooves 306, and both the first clamping plate 302 and the second clamping plate 303 have first inclined grooves 307.

[0025] The feeding assembly 4 includes a vertical cavity 401 formed on the processing table 101. An electric telescopic rod 402 is fixedly installed in the vertical cavity 401. A feeding plate 404 is fixedly installed on the output end of the electric telescopic rod 402. A feeding groove 405 is formed on the feeding plate 404. A first conveyor belt 406 is rotatably installed on the processing table 101. The first conveyor belt 406 is evenly provided with placement grooves that cooperate with the feeding groove 405.

[0026] A guide telescopic tube 407 is installed between the mounting plate 205 and the mounting bracket 102. An air pipe 408 connected to the guide telescopic tube 407 is inserted into the vertical cavity 401. A horizontal groove is opened on the processing table 101. A push block 403 is slidably installed in the horizontal groove. A switch 409 electrically connected to the electric telescopic rod 402 is fixedly installed in the horizontal groove. An air pipe 408 connected to the guide telescopic tube 407 is fixedly installed on the horizontal groove.

[0027] By adopting the above technical solution, the user can evenly place the lead screw in the placement groove. Then, as the electric push rod 204 moves the tapping machine 207 and drilling machine 206 through the mounting plate 205, the guide telescopic tube 407 can limit the movement of the mounting plate 205, thereby ensuring that the mounting plate 205 moves horizontally and effectively preventing the tapping machine 207 from deviating and affecting processing efficiency. When the output end of the electric push rod 204 extends and drives the drilling machine 206 to process the lead screw through the mounting plate 205, the lowest first clamping plate 302 is in a vertical state. Next, during the movement of the mounting plate 205, the mounting plate 205 stretches the guide telescopic tube 407. At this time, the guide telescopic tube 407 draws air from the horizontal groove through the air pipe 408. Since the maximum expansion volume of the guide telescopic tube 407 is designed to be much larger than the internal working volume of the horizontal groove, when the guide telescopic tube 407 draws air from the horizontal groove through the air pipe 408, a high negative pressure is created in the horizontal groove. Then, under the action of pressure, the push block 403 moves along the horizontal groove and presses the trigger switch 409. After the switch 409 is triggered, the output end of the electric telescopic rod 402 extends and drives the feeding plate 404 to move upward. During the upward movement of the feeding plate 404, the feeding plate 404 drives the feeding groove 405 to move upward, so that the feeding groove 405 gradually contacts the lead screw. Subsequently, the feeding plate 404 drives the lead screw to move upward through the feeding groove 405. During the upward movement of the lead screw, the lead screw gradually contacts the first inclined groove 307 and applies a thrust to the first inclined groove 307. Then, under the action of the thrust, the first clamping plate 302 and the second clamping plate 303 move away from each other, compressing the first spring 304 and the second spring 305 respectively. When the lead screw enters the arc-shaped groove 306, the first spring 304 and the second spring 305 extend, respectively driving the first clamping plate 302 and the second clamping plate 303 to move closer together. Furthermore, during the process of the first clamping plate 302 and the second clamping plate 303 moving closer together, the lead screw can be clamped by the arc-shaped groove 306, thus eliminating the need for manual loading by the user and further improving processing efficiency.

[0028] like Figure 2 , Figure 7 As shown, a fixing rod 501 is symmetrically slidably mounted on the side wall of the mounting block 301. A third spring 502 is installed between the fixing rod 501 and the mounting block 301. The first clamping plate 302 and the second clamping plate 303 are both provided with fixing holes 503 that cooperate with the corresponding fixing rod 501. A push plate 504 that cooperates with the fixing rod 501 is fixedly mounted on the mounting plate 201, and a second inclined groove 505 that cooperates with the push plate 504 is provided on the fixing rod 501.

[0029] By adopting the above technical solution, after the lead screw is clamped by the lowermost first clamping plate 302 and second clamping plate 303, the rotating roller 202 is driven to rotate by the motor 203, which in turn drives the lowermost mounting block 301 to rotate. During the rotation of the mounting block 301, it drives the second inclined grooves 505 of the two fixing rods 501 to contact the push plate 504 respectively, and then the push plate 504 applies a pushing force to the second inclined grooves 505 of the fixing rods 501. Under the action of this pushing force, the fixing rods 501 move and compress the third spring 502. During the movement of the two fixing rods 501, they gradually insert into the corresponding fixing holes 503 and fix the first clamping plate 302 and the second clamping plate 303. In this way, the first clamping plate 302 and the second clamping plate 303 can be fixed before the lead screw is processed. It should be noted that the push plate 504 covers the processing dwell area of ​​drilling and tapping in the circumferential direction. During the static stagnation period when the lead screw of the drilling machine 206 and tapping machine 207 is being processed, the push plate 504 can continuously press the fixing rod 501 to maintain the clamping and locking state, prevent loosening due to equipment vibration, effectively avoid the first clamping plate 302 and the second clamping plate 303 moving during the lead screw processing and affecting the processing efficiency, and further improve the processing efficiency.

[0030] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a guide plate 601 is fixedly installed on the mounting plate 205, and a second conveyor belt 602 is fixedly installed on the processing table 101. The second conveyor belt 602 is evenly provided with conveying grooves.

[0031] The mounting block 301 has a linkage groove, and the first clamping plate 302 is fixedly mounted with a linkage plate 603 that slides with the linkage groove. The side wall of the linkage plate 603 away from the first clamping plate 302 is inclined. The guide plate 601 is fixedly mounted with an mounting rod 604, and a horizontal rod 605 is fixedly mounted on the mounting rod 604.

[0032] By adopting the above technical solution, when the rotating roller 202 drives the finished lead screw away from the tapping machine 207 through the clamping assembly 3, the push plate 504 disengages from the clamping assembly 3 holding the finished lead screw. At this time, the corresponding third spring 502 drives the fixing rod 501 to reset and disengages the fixing rod 501 from the corresponding fixing hole 503, thereby releasing the fixation of the first clamping plate 302 with the finished lead screw. Then, as the output end of the electric push rod 204 extends and drives the mounting plate 205 to move, the mounting plate 205 drives the guide plate 601 to move, and during the movement of the guide plate 601, it drives the horizontal rod 605 to move through the mounting rod 604. During the movement of the horizontal rod 605, it gradually contacts the inclined surface of the linkage plate 603 and applies a pushing force to the inclined surface of the linkage plate 603. Under the action of the pushing force, the linkage plate 603 moves along the linkage groove, and during the movement of the linkage plate 603, it drives the first clamping plate 302 to move and compresses the first spring 304. As the first clamping plate 302 moves, it gradually moves away from the second clamping plate 303. Then, under the influence of gravity, the lead screw falls onto the guide plate 601 and moves along the guide plate 601 into the conveyor trough. Next, the second conveyor belt 602 drives the finished lead screw to move. In this way, the finished lead screw can be unloaded while processing is being performed, further improving processing efficiency.

[0033] When the output end of the electric push rod 204 retracts, the mounting plate 205 drives the guide plate 601 to reset. During the reset process of the guide plate 601, the mounting rod 604 drives the horizontal rod 605 to reset and disengage from the linkage plate 603. At this time, the first spring 304 extends and drives the first clamping plate 302 to reset with the linkage plate 603. Simultaneously, during the reset process of the mounting plate 205, the guide telescopic tube 407 is compressed. At this time, the airflow in the guide telescopic tube 407 flows into the horizontal groove through the air pipe 408, increasing the pressure in the horizontal groove. Then, under the action of pressure, the push block 403 resets and disengages from the switch 409. At this time, the output end of the electric telescopic rod 402 retracts and drives the feeding plate 404 to reset downward, preparing for the next operation.

[0034] like Figure 7 , Figure 8 As shown, the end of the fixed rod 501 away from the second inclined groove 505 is provided with a pushing groove 701, and anti-slip pads 702 are fixedly installed in the arc-shaped groove 306.

[0035] A guide block 703 is fixedly installed on the top wall of the feeding plate 404, and a guide groove 704 is provided on the guide block 703.

[0036] like Figure 1 As shown, a pressure relief hole 705 is provided on the horizontal groove.

[0037] By adopting the above technical solution, when the fixing rod 501 is inserted into the fixing hole 503, the push groove 701 facilitates the insertion of the fixing rod 501 into the fixing hole 503. In addition, when the fixing rod 501 is inserted into the push groove 701, the side wall of the push groove 701 applies a pushing force to the side wall of the fixing hole 503, and applies prestress to the first clamping plate 302 and the second clamping plate 303 through the fixing hole 503, thereby improving the clamping effect of the first clamping plate 302 and the second clamping plate 303 on the lead screw. Furthermore, when the first clamping plate 302 and the second clamping plate 303 clamp the lead screw through the arc groove 306, the first clamping plate 302 and the second clamping plate 303 drive the anti-slip pad 702 to contact the lead screw and compress the anti-slip pad 702, thereby further improving the clamping effect of the lead screw.

[0038] When the first conveyor belt 406 drives the lead screw to move towards the upper material plate 404, the first conveyor belt 406 first drives the lead screw to contact the guide groove 704 of the guide block 703. Then, the guide block 703 centers the lead screw through the guide groove 704, so that the user does not need to manually straighten the lead screw, which further improves the processing efficiency. In addition, by opening the pressure relief hole 705, when the guide telescopic tube 407 drives the push block 403 to slide along the horizontal groove through the airflow, the pressure relief hole 705 can balance the pressure in the space of the push block 403 away from the air pipe 408 in the horizontal groove, thereby ensuring that the push block 403 can slide normally along the horizontal groove under the action of the airflow, which plays a role in ensuring the normal operation of the device.

[0039] Instructions for use: First, place the ball screw to be processed evenly in the placement groove of the first conveyor belt 406. The screw is conveyed to the feeding plate 404 by the conveyor belt and automatically centered and corrected by the guide groove 704 of the guide block 703 to complete the pre-feeding positioning.

[0040] Then, after the equipment is started, the electric push rod 204 drives the mounting plate 205 to move, stretching the guide telescopic tube 407 and creating negative pressure in the horizontal groove through the air pipe 408. Subsequently, the push block 403 triggers the switch 409, causing the electric telescopic rod 402 to move the feeding plate 404 upward and push the lead screw to the first inclined groove 307 of the clamping assembly 3, causing the first clamping plate 302 and the second clamping plate 303 to open. After the lead screw enters the arc groove 306, under the action of the first spring 304 and the second spring 305, the first clamping plate 302 and the second clamping plate 303 automatically clamp, and the anti-slip pad 702 improves the clamping stability.

[0041] Motor 203 drives rotating roller 202 to rotate, which in turn drives mounting block 301 that has clamped lead screw to rotate. The second inclined groove 505 of fixed rod 501 contacts push plate 504. Push plate 504 pushes fixed rod 501 into fixed hole 503 of clamping plate to complete clamping mechanism locking and prevent loosening during processing.

[0042] During processing, the rotating roller 202 rotates continuously, feeding the lead screw sequentially to the drilling machine 206 and tapping machine 207 stations; the electric push rod 204 extends, driving the drilling machine 206 and tapping machine 207 to feed synchronously, achieving simultaneous drilling and tapping. During processing, the guide telescopic tube 407 ensures that the mounting plate 205 moves horizontally, preventing deviation.

[0043] Furthermore, after the lead screw is finished, it rotates out of the processing area with the rotating roller 202. The push plate 504 disengages from the fixed rod 501, and the third spring 502 drives the fixed rod 501 to reset and release the lock. When the electric push rod 204 extends, the mounting plate 205 drives the horizontal rod 605 to push the linkage plate 603, causing the first clamping plate 302 to open. Under the action of gravity, the lead screw falls into the guide plate 601 and slides into the conveying groove of the second conveyor belt 602.

[0044] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
