Description
Double-head lathe for bit production Technical Field
[0001] This application relates to the field of lathes, and more particularly to a double-headed lathe for bit production. Background Technology
[0002] Screwdriver bits, generally speaking, refer to the screwdriver heads that are mounted on electric drills or hammer drills for tightening screws. Electric screwdriver bits are electric screwdrivers used to tighten or loosen screws and belong to small power tools. Screwdriver bits can be classified into different types according to their head shape, such as slotted, Phillips, star, square, or hexagonal.
[0003] In the production of screwdriver bits in the existing technology, one end of the bit along the axis is first flattened and grooved, and the other end along the axis is then flattened to form a head shape such as a straight line, cross, or star.
[0004] However, existing lathes can usually only process the bit in one direction. If bidirectional processing is required, the bit must first be flattened and grooved at one end before the other end is flattened. This requires workers to constantly feed and unload materials, increasing their workload, extending the processing cycle, and thus increasing the production cost of the bit. Summary of the Invention
[0005] To improve the production cost of bit manufacturing, this application provides a double-head lathe for bit manufacturing.
[0006] This application provides a double-head lathe for bit production, which adopts the following technical solution:
[0007] A double-head lathe for bit production includes a machine base, a shifting device, a flat-head machining device, and a surface machining device. The flat-head machining device includes a flat-head cutting assembly and a first spindle. The first spindle is rotatably connected to the surface of the machine base and can clamp and rotate the end of a bit. The flat-head cutting assembly is connected to the surface of the machine base facing the first spindle and can perform flat-head cutting on the end face of the bit clamped by the first spindle. The surface machining device includes a surface cutting assembly and a second spindle. The second spindle is rotatably connected to the surface of the machine base, and the axis of the second spindle is parallel to the axis of the first spindle. The second spindle can clamp and rotate the end of a bit. The surface cutting assembly is connected to the surface of the machine base facing the second spindle and can perform milling and turning machining on the end face of the bit clamped by the second spindle. The shifting device includes... The machine includes a push-pull rod and a conversion assembly. The conversion assembly is slidably connected to the surface of the machine base. The insertion end of the conversion assembly is for inserting the bit and driving the bit to rotate. The push-pull rod is slidably connected to the surface of the machine base. The sliding direction of the push-pull rod coincides with the axis of the first spindle. When the conversion assembly slides towards the first spindle, the insertion end of the conversion assembly faces the clamping end of the first spindle. The end of the push-pull rod is inserted into the inner cavity of the spindle and pushes the bit into the insertion end of the conversion assembly. The conversion assembly drives the bit to rotate. When the conversion assembly slides towards the second spindle, the insertion end of the conversion assembly faces the clamping end of the second spindle. The conversion assembly pushes the end of the bit that has been flat-cut into the clamping end of the second spindle. The clamping end of the second spindle clamps the bit end and rotates it. The flat cutting assembly performs planar milling on the unprocessed bit end.
[0008] By adopting the above technical solution, when both ends of the bit along the axial direction require milling, the spindle coaxially clamps the bit end and drives the bit to rotate. Simultaneously, the flat-end cutting assembly performs a flat-end cutting on the bit end face clamped by the spindle, thus completing the milling of one end of the bit along the axial direction. The conversion assembly slides along the machine base surface towards the spindle, with its insertion end facing the clamping end of the spindle. The push-pull rod slides along the machine base surface towards the spindle, its end embedding into the spindle cavity and pushing the bit end into the insertion end of the conversion assembly. The conversion assembly then drives the bit... As the machine rotates, the conversion component slides along the surface of the base toward the direction of the second spindle. The insertion end of the conversion component faces the clamping end of the second spindle. The conversion component pushes the end of the bit with the flat-head cut into the clamping end of the second spindle. The clamping end of the second spindle clamps the bit end and rotates. At the same time, the flat cutting component performs flat milling on the unprocessed bit end, realizing automated milling on both ends of the bit along the axial direction. This eliminates the need for continuous loading and unloading operations by the operator, reducing the workload of the operator, shortening the processing cycle of the bit, and thus reducing the production cost of the bit.
[0009] Optionally, the conversion assembly includes a sliding seat, a translation seat, a conversion seat, and a conversion rod. The sliding seat is slidably connected to the surface of the machine base. The sliding direction of the sliding seat is parallel to the axis of the first spindle and parallel to the length direction of the machine base. The translation seat is slidably connected to the surface of the sliding seat. The sliding direction of the translation seat is parallel to the width direction of the machine base. The conversion seat is rotatably connected to the surface of the translation seat. The rotation axis of the conversion seat is parallel to the height direction of the machine base. The surface of the conversion seat has a groove for inserting a bit. The groove extends through both sides of the conversion seat. The conversion rod is slidably connected to the surface of the translation seat. The sliding direction of the conversion rod is parallel to the axis of the first spindle. The conversion rod is located on the side of the conversion seat away from the second spindle. When the groove faces the clamping end of the second spindle, the end of the conversion rod is inserted into the groove and pushes the bit in the groove into the clamping end of the second spindle.
[0010] By adopting the above technical solution, when the end of the bit held by the spindle is finished with milling, the sliding seat slides along the machine base surface towards the spindle, and at the same time, the translation seat slides along the sliding seat surface towards the spindle, with the groove facing the clamping end of the spindle. The push-pull rod slides along the machine base surface towards the spindle, and the end of the push-pull rod is embedded in the inner cavity of the spindle, pushing the end of the bit into the groove. The inner wall of the groove abuts against the outer circumferential surface of the bit to form a limit. At the same time, the conversion seat rotates on the surface of the translation seat to realize the reversal of the bit. The translation seat slides along the surface of the sliding seat towards the direction of spindle two. The end of the bit milled by the flat-head turning in the groove faces the clamping end of spindle two. The conversion rod slides along the surface of the translation seat towards the direction of the conversion seat. The end of the conversion rod is inserted into the groove and pushes the end of the bit in the groove into the clamping end of spindle two. This realizes the automatic feeding and unloading of the bit on spindle one and spindle two, eliminating the need for manual feeding and unloading by the operator, improving the processing efficiency of the bit, shortening the processing cycle of the bit, and thus reducing the processing cost of the bit.
[0011] Optionally, the conversion assembly further includes a feeding rod, a feeding cylinder, and a feeding hopper. The feeding cylinder is connected to the surface of the translation seat, and the axis of the feeding cylinder is parallel to the axis of the second main shaft. The inner cavity of the feeding cylinder is for inserting the screwdriver bit. The feeding hopper is connected to the surface of the machine base, and the inner cavity of the feeding hopper is for storing the screwdriver bit. The feeding hopper is located on the side of the translation seat away from the second main shaft. The feeding rod is slidably connected to the surface of the machine base, and the sliding direction of the feeding rod coincides with the axis of the second main shaft. When the translation seat slides towards the second main shaft, and the inner cavity of the feeding cylinder faces the clamping end of the second main shaft, the end of the feeding rod is embedded in the inner cavity of the second main shaft and pushes the screwdriver bit through the inner cavity of the feeding cylinder and into the inner cavity of the feeding hopper.
[0012] By adopting the above technical solution, when the milling of the end face of the bit held by the second spindle is completed, the translation seat is driven to slide along the surface of the sliding seat towards the second spindle. One end of the feed cylinder in the axial direction faces the clamping end of the second spindle, and the other end of the feed cylinder in the axial direction faces the opening of the feed hopper. The feed rod slides along the surface of the machine base towards the second spindle. The end of the feed rod is embedded in the inner cavity of the second spindle and pushes the bit through the inner cavity of the feed cylinder and into the inner cavity of the feed hopper, realizing automated feeding of the bit. There is no need for the operator to manually take out the bit for feeding, which further improves the automation of bit processing and thus improves the processing efficiency of bit.
[0013] Optionally, the flat-head cutting assembly includes a horizontal seat, a vertical seat, and a cutting tool. The horizontal seat is slidably connected to the surface of the machine base, and the sliding direction of the horizontal seat is parallel to the length direction of the machine base. The vertical seat is slidably connected to the surface of the horizontal seat, and the sliding direction of the vertical seat is parallel to the height direction of the machine base. The cutting tool is connected to the surface of the vertical seat facing the spindle, and the cutting end of the cutting tool can perform flat-head milling on the end of the bit held by the spindle.
[0014] By adopting the above technical solution, when the spindle clamps the end of the bit, the transverse seat slides along the surface of the machine base toward the spindle, the cutting end of the cutting tool faces the end of the bit clamped by the spindle, the vertical seat slides along the surface of the transverse seat toward the spindle, the cutting end of the cutting tool abuts against the end of the bit, and the spindle drives the bit to rotate, thereby achieving the precision of milling and turning the end face of the bit.
[0015] Optionally, the planar cutting assembly includes an adjusting seat, a cutting seat, a cutting motor, a first milling cutter, and a second milling cutter. The adjusting seat is connected to the surface of the translation seat, and the cutting seat is slidably connected to the surface of the adjusting seat facing the second spindle. The sliding direction of the cutting seat is parallel to the height direction of the machine base. The cutting motor is connected to the surface of the cutting seat facing the second spindle, and the motor axis of the cutting motor is parallel to the height direction of the machine base. The first milling cutter is connected to the end of the motor shaft of the cutting motor. The cutting end of the first milling cutter can perform planar milling on the end of the bit held by the second spindle. The second milling cutter is connected to the surface of the translation seat facing the second spindle, and the cutting end of the second milling cutter can perform planar milling on the end of the bit held by the second spindle.
[0016] By adopting the above technical solution, when the spindle 2 clamps the end of the bit, the translation seat slides along the surface of the sliding seat towards the spindle 2, and the cutting end of the milling cutter 2 abuts against the end face of the bit held by the spindle 2. The spindle 2 drives the bit to rotate around its own axis, thus completing the initial milling of the bit end face by the milling cutter 2. At the same time, the translation seat continues to slide along the surface of the sliding seat, and the cutting seat slides along the surface of the adjusting seat towards the spindle 2. The cutting end of the milling cutter 1 abuts against the end face of the bit held by the spindle 2, and the cutting motor drives the milling cutter 1 to rotate. The milling cutter 1 then completes the secondary milling of the bit end face, thereby improving the accuracy of the milling of the bit.
[0017] Optionally, a feeding assembly is also included, comprising a feeding cylinder, a slide rail, a feeding rod, and a feeding plate. A slide rail for sliding the screwdriver bits is formed on the surface of the machine base. The sliding direction of the screwdriver bits is parallel to the length direction of the machine base. The feeding plate is connected to the surface of the machine base, and the inclination height of the feeding plate surface decreases as the distance to the slide rail decreases. The screwdriver bits in the vibrating disc enter the slide rail along the surface of the feeding plate. The feeding rod is slidably connected to the inner wall of the slide rail, and the feeding rod can push the screwdriver bits to slide along the inner wall of the slide rail. The slide rail is connected to the surface of the machine base and is located between the push-pull rod and the main shaft. The feeding cylinder is slidably connected to the surface of the slide rail. The inner cavity of the feeding cylinder is for inserting the screwdriver bit. When the feeding cylinder approaches the slide rail along the surface of the slide rail, the opening of the feeding cylinder faces the slide rail, and the feeding rod pushes the screwdriver bit in the slide rail to insert into the inner cavity of the feeding cylinder. When the feeding cylinder approaches the main shaft along the surface of the slide rail, the opening of the feeding cylinder faces the push-pull rod, and the end of the push-pull rod is inserted into the inner cavity of the feeding cylinder and pushes the screwdriver bit in the feeding cylinder to insert into the inner cavity of the main shaft.
[0018] By adopting the above technical solution, during bit processing, the bit in the vibratory feeder enters the inner cavity of the slide along the surface of the feeding plate. The feeding cylinder slides along the surface of the slide rail towards the slide, with the opening of the feeding cylinder facing the slide. The feeding rod pushes the bit in the slide to embed into the inner cavity of the feeding cylinder. The feeding cylinder slides along the surface of the slide rail towards the spindle, with the opening of the feeding cylinder facing the push-pull rod. The push-pull rod slides along the surface of the machine base towards the feeding cylinder. The end of the push-pull rod embeds into the inner cavity of the feeding cylinder and pushes the bit in the feeding cylinder into the inner cavity of the spindle. The clamping end of the spindle clamps the end of the bit, realizing automated feeding of the spindle and further improving the degree of automated bit processing, thereby improving the processing efficiency of the bit.

[0021] Optionally, a typing assembly is also included, comprising a stamping cylinder, a stamping base, and a stamping die. The stamping base is connected to the surface of the machine base facing the slide, and the stamping cylinder is connected to the surface of the stamping base. The piston rod axis of the stamping cylinder is parallel to the height direction of the machine base. The piston rod of the stamping cylinder passes through the surface of the stamping base and is connected to the surface of the stamping die. The stamping end of the stamping die faces the bit end face in the slide. When the piston rod of the stamping cylinder extends, it drives the stamping die closer to the slide, and the stamping die punches a steel stamp into the bit surface in the slide.
[0022] By adopting the above technical solution, when a steel stamp needs to be engraved on the surface of the bit, the feeding rod pushes the bit in the slide to slide, and the end face of the bit in the slide faces the stamping end of the stamping die. The piston rod of the stamping cylinder extends, and the stamping cylinder drives the stamping die to approach the slide. The stamping die punches and recesses the surface of the bit in the slide to form a steel stamp, thereby realizing the automation of engraving steel stamps on the surface of the bit and further improving the processing efficiency of the bit.

The motor axis of the cutting motor 423 is parallel to the height direction of the seat 11. The end of the motor shaft of the cutting motor 423 passes through the surface of the cutting seat 422 and is fixed to the end face of the first milling cutter 424. The second milling cutter 425 is fixed to the surface of the translation seat 222 facing the second spindle 41 by bolts.
[0044] Referring to Figures 1 and 3, when the clamping end of the spindle 2 41 holds the bit end, the translation seat 222 slides along the surface of the sliding seat 221 towards the spindle 2 41. The cutting end of the milling cutter 2 425 abuts against the bit end held by the spindle 2 41, and the milling cutter 2 425 performs planar milling on the bit end held by the spindle 2 41, thus completing the initial milling of the bit end. The translation seat 222 continues to slide along the surface of the sliding seat 221, and the milling cutter 1 424 moves towards the spindle 2 41. The adjusting motor 426 drives the adjusting screw 427 to rotate, causing the cutting seat 422 to slide along the axis of the adjusting screw 427 on the surface of the adjusting seat 421. The cutting end of the milling cutter 425 abuts against the end of the bit held by the spindle 41. The milling cutter 424 performs planar milling on the end of the bit held by the spindle 41, realizing automated planar milling of the bit end, further improving the degree of automation of bit processing, thereby improving the processing efficiency of bit processing.
[0045] Referring to Figures 2 and 4, the base 1 also includes a sliding part 2 15, an adjusting part 2 16, and a screw 2 17. The sliding part 2 15 is connected to the surface of the base 11 and is located on the side of the main shaft 2 41 away from the sliding seat 221. The end of the screw 2 17 is rotatably connected to the end face of the sliding part 2 15. The axis of the screw 2 17 is parallel to the height direction of the base 11. The adjusting part 2 16 is threaded to the outer circumferential surface of the screw 2 17. The adjusting part 2 16 slides along the axis of the screw 2 17 on the surface of the sliding part 2 15 to achieve precise adjustment of the height of the adjusting part 2 16.
[0046] Referring to Figures 2 and 4, the feeding assembly 5 includes a feeding cylinder 51, a slide rail 52, a feeding rod 53, and a feeding plate 54. The end face of the adjustment part 2 16 is provided with a slide 161 for the bit to slide. The sliding direction of the bit is parallel to the length direction of the base 11. The feeding plate 54 is fixed to the surface of the adjustment part 2 16 facing the slide 161 by bolts. The tilt height of the feeding plate 54 decreases as the distance to the slide 161 decreases. The bit in the vibrating plate enters the slide 161 along the surface of the feeding plate 54, realizing the directional feeding of the bit in the slide 161. The feeding rod 53 is slidably connected to the inner wall of the slide 161. The feeding rod 53 is located on the side of the slide 161 away from the main shaft 2 41. When the feeding rod 53 slides on the inner wall of the slide 161, it pushes the bit to slide on the inner wall of the slide 161. In this embodiment, the feeding rod 53 is driven to slide by a cylinder.
[0047] Referring to Figures 1 and 3, the slide rail 52 is connected to the surface of the adjustment part 2 16 facing the main shaft 2 41. The tilt height of the slide rail 52 decreases as the distance to the main shaft 1 32 decreases. The slide rail 52 is located between the push-pull rod 21 and the main shaft 1 32. The feeding cylinder 51 includes a block 511 and a cylinder 512. The block 511 is slidably connected to the surface of the slide rail 52, and the cylinder 512 is threadedly connected to the surface of the block 511. The axis of the cylinder 512 is parallel to the length direction of the seat 11. The inner cavity of the cylinder 512 is for inserting the bit.
[0048] Referring to Figures 1 and 3, when the block 511 slides along the surface of the slide rail 52 toward the slide 161, the opening of the cylinder 512 faces the groove of the slide 161, and the feeding rod 53 slides along the inner wall of the slide 161 toward the cylinder 512. The rod surface of the feeding rod 53 abuts against the end face of the bit and drives the end of the bit to be coaxially embedded into the inner cavity of the cylinder 512. The inner wall of the cylinder 512 abuts against the outer circumferential surface of the bit to form a limit. At the same time, the distance from the opening of the cylinder 512 to the slide 161 can be achieved by rotating the position of the cylinder 512 on the block 511, so that the bit in the slide 161 can be stably embedded into the inner cavity of the cylinder 512, thereby improving the stability of feeding into the inner cavity of the cylinder 512.
[0049] Referring to Figures 1 and 3, when the block 511 slides along the surface of the slide rail 52 toward the direction close to the spindle 32, the axis of the push-pull rod 21, the axis of the cylinder 512, and the axis of the spindle 32 coincide. The push-pull rod 21 slides along the surface of the adjustment part 13 toward the direction close to the cylinder 512. The end of the push-pull rod 21 is embedded in the inner cavity of the cylinder 512 and pushes the bit into the inner cavity of the spindle 32. The inner cavity of the spindle 32 allows multiple bits to be embedded coaxially at intervals in sequence, realizing stable feeding of bits at the clamping end of the spindle 32 and further improving the automation of bit turning and milling.
[0050] Referring to Figures 1 and 3, the typing assembly 6 includes a stamping cylinder 61, a stamping seat 62, and a stamping type 63. The stamping seat 62 is connected to the surface of the adjusting part 16 facing the slide rail 161. The stamping cylinder 61 is fixed to the top surface of the stamping seat 62 by bolts. The piston rod axis of the stamping cylinder 61 is parallel to the height direction of the seat 11. The piston rod end of the stamping cylinder 61 passes through the surface of the stamping seat 62 and is fixed to the surface of the stamping type 63.
[0051] Referring to Figures 1 and 3, when the bit in the slide 161 faces the stamping end of the stamping die 63, the piston rod of the stamping cylinder 61 extends, and the stamping die 63 punches and recesses the surface of the bit in the slide 161 to form a steel stamp, thereby realizing the automated processing of engraving steel stamps on the surface of the bit.
[0052] The implementation principle of a double-head lathe for bit production in this application embodiment is as follows: the bit in the vibratory plate enters the slide 161 along the surface of the feeding plate 54, the block 511 slides along the surface of the slide rail 52 toward the slide 161, the opening of the cylinder 512 faces the groove of the slide 161, the feeding rod 53 slides along the inner wall of the slide 161 toward the cylinder 512, the rod surface of the feeding rod 53 abuts against the end face of the bit and drives the end of the bit to be coaxially embedded into the inner cavity of the cylinder 512, and the inner wall of the cylinder 512 abuts against the outer peripheral surface of the bit to form a limit; Block 511 slides along the surface of slide rail 52 toward the direction of main shaft 32. The axis of push rod 21, the axis of cylinder 512, and the axis of main shaft 32 coincide. Push rod 21 slides along the surface of adjustment part 13 toward the direction of cylinder 512. The end of push rod 21 is embedded in the inner cavity of cylinder 512 and pushes the bit into the inner cavity of main shaft 32. The inner cavity of main shaft 32 allows multiple bits to be embedded coaxially at intervals in sequence, realizing stable feeding of bits at the clamping end of main shaft 32. When the clamping end of main shaft 32 clamps the bit, the drive horizontal The vertical seat 311 slides on the surface of the seat 11, so that the cutting end of the cutting tool 313 and the end of the bit held by the spindle 32 are on the same plane. The vertical seat 312 slides along the surface of the horizontal seat 311, and the cutting end of the cutting tool 313 abuts against the end of the bit held by the spindle 32. The spindle 32 holds the end of the bit and drives the bit to rotate around its own axis, improving the accuracy of the cutting tool 313 in the milling and turning of the bit end. The translation seat 222 slides along the surface of the sliding seat 221 toward the spindle 32, and the groove 223 is inserted. The slot faces the end of the bit held by the spindle 32. The sliding seat 221 slides along the surface of the seat 11 toward the spindle 32. The end of the bit protruding from the spindle 32 is embedded in the groove 2231. At the same time, the push-pull rod 21 slides along the surface of the adjustment part 13 toward the spindle 32. The end of the push-pull rod 21 is embedded in the inner cavity of the spindle 32 and pushes the end of the bit, causing the bit to slide toward the groove 2231. The bit is disengaged from the clamping end of the spindle 32, realizing the feeding of the bit in the groove 2231.The converter seat 223 rotates on the surface of the translation seat 222, causing the bit to rotate and change direction. The end of the bit with the flat end cut and milled faces the spindle 32, driving the translation seat 222 to slide along the surface of the sliding seat 221 towards the spindle 41. The end of the bit with the flat end cut and milled in the groove 2231 faces the clamping end of the spindle 41. The sliding seat 221 slides along the surface of the seat 11 towards the spindle 41, shortening the distance between the converter seat 223 and the spindle 41. The conversion rod 224 slides along the surface of the translation seat 222 towards the groove 2231. The end of the conversion lever 224 is inserted into the groove 2231 and pushes the bit to slide towards the spindle 2 41. The end of the bit with the flat end cut and milled is inserted into the clamping end of the spindle 2 41. The translation seat 222 slides along the surface of the sliding seat 221 towards the spindle 2 41. The cutting end of the milling cutter 2 425 abuts against the end of the bit clamped by the spindle 2 41. The milling cutter 2 425 performs planar milling on the end of the bit clamped by the spindle 2 41, completing the initial milling of the bit end. The translation seat 222 continues to slide along the surface of the sliding seat 221, and the milling cutter 1 424 moves towards the spindle 2 41. The end of the clamped bit is controlled by the adjusting motor 426, which drives the adjusting screw 427 to rotate. This causes the cutting seat 422 to slide along the axis of the adjusting screw 427 on the surface of the adjusting seat 421. The cutting end of the milling cutter 425 abuts against the end of the bit held by the spindle 41. The milling cutter 424 performs planar milling on the end of the bit held by the spindle 41, thus achieving automated planar milling of the bit end. The translation seat 222 slides along the surface of the sliding seat 221. One end of the unloading cylinder 226 faces the clamping end of the planar machining device 4, and the other end faces... The feeding hopper 227 has an opening, and the feeding rod 225 slides along the base surface towards the plane machining device 4. The end of the feeding rod 225 is embedded in the inner cavity of the plane machining device 4 and pushes the bit towards the feeding cylinder 226, causing the bit to pass through the inner cavity of the feeding cylinder 226 and into the inner cavity of the feeding hopper 227. This achieves automated feeding of the bit and automated milling and turning at both ends of the bit along its axis. It eliminates the need for continuous loading and unloading operations by workers, reducing workload, shortening the bit processing cycle, and thus lowering the production cost of the bit.
