Description

Technical Field

[0001] This invention relates to the field of tap processing technology, and more specifically to a tap chip removal machine. Background Technology

[0002] A tap is a cutting tool used for machining internal threads. Based on shape, it can be divided into spiral taps and straight-edged taps. Based on usage environment, it can be divided into hand taps and machine taps. Taps require processes such as turning the outer diameter, quenching, external grinding, squaring, grooving, external grinding, thread grinding, tip trimming, and passivation to become a finished tap. During the manufacturing process, small burrs or flash will be generated on the cutting edge. If these burrs are not treated, they will scratch the workpiece thread surface during cutting, leading to a decrease in thread accuracy. To ensure the quality of the finished tap, the finished tap needs to be surface-polished. Polishing the tap edge is an important process in machining; its core purpose is to optimize the tap's cutting performance, extend its service life, and ensure that the machined thread meets accuracy requirements. Existing equipment can only grind a single tap at a time when grinding the edge of a tap, resulting in low grinding efficiency and making it impossible to grind a batch of taps. Similarly, when manually grinding taps with an electric grinding tool, the problems of low grinding efficiency and safety hazards also exist.

[0003] Therefore, the present invention provides a tap chip removal machine to solve the above-mentioned problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a tap chip removal machine, which effectively solves the problem that existing equipment can only grind a single tap at a time, resulting in low grinding efficiency and the inability to grind batches of taps.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A tap chip removal machine includes a machine tool. The machine tool has an internal drive assembly. A grinding clamping disc is located at the front end of the drive assembly. Multiple clamping shells are uniformly fixedly installed at the front end of the grinding clamping disc. Each clamping shell has a movable clamping rod slidably installed at both ends. A clamping block located inside the clamping shell is fixedly installed at one end of each movable clamping rod. A push rod is rotatably installed at the other end of each movable clamping rod. Every two corresponding push rods are rotatably connected. Multiple limiting holes are uniformly opened on each grinding clamping disc. A sliding rod located inside the limiting hole is installed on the hinged end of every two corresponding push rods. A limiting shell located behind the grinding clamping disc is fixedly sleeved on each sliding rod. A return spring is fixedly installed on each limiting shell. A grinding assembly is located on the left side of the machine tool, and a feeding assembly is located on the right side of the machine tool. A tap is located inside the feeding assembly.

[0006] Preferably, the grinding assembly includes a machine tool base plate, a sliding housing is slidably mounted on the left end of the machine tool base plate, a grinding motor is fixedly mounted on the bottom end of the sliding housing, a grinding disc is fixedly mounted on the rear shaft of the grinding motor, and a drive telescopic rod is fixedly mounted on the machine tool base plate.

[0007] Preferably, the drive assembly includes a device body, a fixed baffle is fixedly installed at the front end of the device body, a grooved wheel is rotatably installed at the rear end of the fixed baffle, a plurality of internal holes are evenly opened on the grooved wheel, the grinding clamping disc is connected to the grooved wheel, a swing rod located below the grooved wheel is rotatably installed at the rear end of the fixed baffle, a drive motor is fixedly installed on the device body, and the swing rod is fixedly installed on the rotating shaft of the drive motor.

[0008] Preferably, each of the clamping shells is fixedly installed with a blocking block, and electromagnet blocks are evenly installed on the grinding clamping plate. Each electromagnet block is set in a corresponding clamping shell, and a driven gear located on the rear side of the grinding clamping plate is fixedly installed on each electromagnet block. A drive gear ring that meshes with each driven gear is rotatably installed at the rear end of the grinding clamping plate, and a power gear located on the rear side of the grinding plate is fixedly installed on the shaft of the grinding motor.

[0009] Preferably, each of the blocking blocks is fixedly equipped with a pad, each of the clamping blocks is provided with a ball bearing, each of the electromagnet blocks is equipped with a push telescopic rod located behind the driven gear, and each of the push telescopic rods is fixedly equipped with a stabilizing frame.

[0010] Preferably, a synchronous wheel is rotatably mounted on the front end of the fixed baffle, a fixed shaft is fixedly mounted on the front end of the synchronous wheel, the grinding clamping disc is rotatably mounted on the fixed shaft, a fixed toothed ring is fixedly mounted on the rear end of the grinding clamping disc, and a built-in motor is fixedly mounted on the fixed shaft.

[0011] Preferably, a top-pressure telescopic rod is fixedly installed on the equipment body, a rear friction disc is fixedly installed at the front end of the top-pressure telescopic rod, and a front friction disc is fixedly installed at the rear end of the grooved wheel.

[0012] Preferably, the feeding assembly includes a feeding tray, a feeding box is inclinedly arranged at the left end of the feeding tray, an auxiliary pressure rod is arranged on the upper part of the feeding box, a guide box is fixedly installed at the lower left end of the feeding box, a trigger pressure rod is fixedly installed at the rear end of the feeding box, a trigger plate is fixedly installed at the rear end of each sliding rod, and an inclined block is arranged at the inner end of each clamping shell.

[0013] Preferably, the auxiliary pressure rod is provided with a first telescopic rod and a second telescopic rod, and a support frame is fixedly installed at the lower end of the feeding box.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By grinding the edge of the tap, burrs on the edge of a batch of taps can be removed, effectively avoiding defects such as scratches and indentations on the surface of the workpiece thread during tapping, ensuring the surface smoothness of the thread. The edge size of the tap after grinding is more uniform and regular, the cutting edge is sharper and the stress distribution is more even. During the tapping process, the sharp cutting edge can reduce the frictional resistance with the workpiece material, avoid the cutting edge from cracking or excessive wear caused by excessive local stress, thereby extending the overall service life of the tap.

[0015] 2. The drive telescopic rod pushes the sliding shell to slide gradually to the right, and the grinding motor drives the grinding disc to rotate and grind the edge of the tap, which improves the quality of the tap. It can also grind the tap without stopping the machine, which improves the grinding efficiency.

[0016] 3. By using the swing rod, drive block, built-in hole and grooved wheel in combination, the grinding clamping plate can be driven to rotate exactly one-tenth of an angle, which makes it easier for the tap to fall into the clamping shell below, thus improving the accuracy of the placement.

[0017] 4. The electromagnet attracts the tap, which makes it easy for the locking teeth to engage with the edge of the tap, thus limiting the tap's position. At the same time, it works in conjunction with the push rod to move the tap forward, allowing the tap to be quickly removed.

[0018] 5. This device achieves automated tap feeding and batch tap grinding without the need for human intervention, thus improving safety. Attached Figure Description

[0021] The following reference Figures 1 to 14 The various embodiments of the present invention will be described in detail. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] Tap chip remover, such as Figure 1 , Figure 3 , Figure 9 , Figure 10 , Figure 14As shown, the device includes a machine tool 1, which is a housing. Inside the machine tool 1 is a drive assembly. At the front end of the drive assembly is a grinding clamping disc 2, which is circular. Multiple clamping shells 3 are evenly fixedly mounted on the front end of the grinding clamping disc 2. The clamping shells 3 are vertically continuous; ten clamping shells 3 are used here. Each clamping shell 3 has a rectangular hole between its left and right ends. A movable clamping rod 4 is slidably mounted in each rectangular hole. Corresponding movable clamping rods 4 can move away from or towards each other. A clamping block 5 is fixedly mounted on one end of each movable clamping rod 4, and each clamping block 5 is located within the cavity of the clamping shell 3. A push rod 6 is rotatably mounted on the other end of each movable clamping rod 4, located on one side of the clamping shell 3. The other ends of corresponding push rods 6 are rotatably connected. The components are connected to form a triangular structure. Each grinding clamping disc 2 has multiple through-holes 7 evenly distributed on it. The limiting holes 7 are located inside the clamping shell 3. The hinged ends of every two push rods 6 are rotatably connected to a sliding rod 8, which is slidably installed within the limiting holes 7. A limiting shell 9 is fixedly fitted onto each sliding rod 8, located on the rear side of the grinding clamping disc 2. A return spring 10 is fixedly installed on each limiting shell 9, with the other end of the return spring 10 fixedly installed on the grinding clamping disc 2. Under normal conditions, due to the elasticity of the return spring 10, the inner ends of the two corresponding moving clamping rods 4 approach each other. A grinding assembly is located on the left side of the machine tool 1, and a feeding assembly is located on the right side of the machine tool 1. A tap 11 is installed inside the feeding assembly. (It should be noted that the component positions in this application are based on...) Figure 1 (For reference only) When the edge of the tap 11 is being ground, the personnel place the produced taps 11 in batches into the feeding assembly. As the feeding assembly works, the corresponding mechanism drives each sliding rod 8 to slide along the limiting hole 7, gradually moving away from the center of the grinding clamping plate 2. The return spring 10 is gradually compressed, and the sliding rod 8 drives the hinge ends of the two push rods 6 to move, thereby causing the two moving clamping rods 4 to move away from each other. The two moving clamping rods 4 quickly open a certain distance, and at this time the tap 11 falls right between the two clamping blocks 5. Then the corresponding mechanism quickly moves away from the sliding rod 8. Due to the elastic force of the return spring 10, the two clamping blocks 5 quickly move closer to each other and clamp the tap 11. Repeat the above steps. When the tap 11 is placed in each clamping shell 3, drive the grinding clamping disk 2 to rotate. The grinding assembly moves to the right and grinds the thread edge of each tap 11. It can grind the taps 11 in batches. After the edge of each tap 11 is finished being ground, the grinding assembly resets to the left, the grinding clamping plate 2 stops rotating, and the corresponding mechanism pushes the tap 11 forward to slide away from the two clamping blocks 5. The tap 11 falls into the appropriate device, and then the above steps are repeated to continue grinding the tap 11. This not only allows for the synchronous grinding of the edges of a batch of taps 11, but also eliminates the need for excessive manual operation, thus improving work efficiency. Because the two clamping blocks 5 hold the tap 11, it is prevented from falling off during the grinding process. Because it can grind and remove burrs from the edges of batches of taps 11, it effectively avoids defects such as scratches and indentations left on the surface of the workpiece thread during tapping, ensuring the surface finish of the thread. The edge size of the tap 11 after grinding is more uniform and regular, the cutting edge is sharper and the stress distribution is more even. During the tapping process, the sharp cutting edge can reduce the frictional resistance with the workpiece material, avoid the cutting edge from cracking or excessive wear caused by excessive local stress, thereby extending the overall service life of the tap 11.

[0023] like Figure 2 , Figure 5 As shown, the grinding assembly includes a machine tool base plate 12, which is fixedly connected to the machine tool equipment 1 to improve stability. Two limit strips are fixedly installed on the top left side of the machine tool base plate 12. A sliding shell 13 is slidably installed between the two limit strips. A grinding motor 14 is fixedly installed on the top of the sliding shell 13. The grinding motor 14 is connected to the power supply and controller. A grinding disc 15 is coaxially fixedly installed on the rear shaft of the grinding motor 14. The grinding disc 15 is located on the front side of the grinding clamping disc 2. During use, the grinding disc 15 can effectively grind the edge of the tap 11. The grinding disc 15 is selected from existing suitable materials and models. A positioning plate is fixedly installed on the left side of the machine tool base plate 12. A drive telescopic rod 16 is fixedly installed on the positioning plate. The telescopic end of the drive telescopic rod 16 is fixedly connected to the sliding shell 13. The drive telescopic rod 16 is an electric telescopic rod or a hydraulic telescopic rod and is connected to the power supply and controller. When the tap 11 is being polished, the drive telescopic rod 16 pushes the sliding shell 13 to slide gradually to the right. When the polishing disc 15 contacts the edge of the tap 11, the drive telescopic rod 16 stops moving to keep the position of the sliding shell 13 from moving. The power is turned on and the controller starts the polishing motor 14 to rotate the polishing disc 15. The polishing disc 15 polishes the edge of each tap 11 to improve the quality of the tap 11. After grinding is completed, the drive telescopic rod 16 pushes the sliding shell 13 to slide to the left to reset, removes the ground tap 11, and waits for subsequent use. The grinding disc 15 can grind the tap 11 well, improving the appearance and quality of the tap 11. At the same time, it can grind the tap 11 without stopping the machine, which improves efficiency.

[0024] like Figure 4 , Figure 7 As shown, the drive assembly includes a device body 17, a machine tool base plate 12 extending into the machine tool equipment 1, a device body 17 fixedly mounted on the machine tool base plate 12, a fixed baffle 18 fixedly mounted at the front end of the device body 17, a grooved wheel 19 rotatably mounted at the rear end of the fixed baffle 18, a plurality of internal holes 20 evenly opened on the edge end of the grooved wheel 19, here ten internal holes 20 are provided, a grinding chuck 2 is connected to the grooved wheel 19, a swing rod 21 located below the grooved wheel 19 is rotatably mounted at the rear end of the fixed baffle 18, a drive block is fixedly mounted at one end of the swing rod 21, the diameter of the drive block is smaller than the inner diameter of the internal hole 20, a drive motor 22 is fixedly mounted on the device body 17, the shaft of the drive motor 22 is coaxially fixedly connected to the other end of the swing rod 21, and the drive motor 22 is connected to the power supply and the controller; When the power is turned on, the controller controls the drive motor 22 to rotate at a suitable speed. The shaft of the drive motor 22 rotates the swing arm 21 and the drive block. The drive block gradually enters the corresponding built-in hole 20. Due to the continuous rotation of the drive motor 22, the drive block drives the grooved wheel 19 and the grinding clamping plate 2 to rotate synchronously. When the drive block moves out of the built-in hole 20, the grooved wheel 19 stops rotating. At this time, the grinding clamping plate 2 rotates exactly one-tenth of an angle, which makes it convenient for the tap 11 to fall into the clamping shell 3 below. Because the grooved wheel 19 rotates intermittently, the tap 11 can be placed in each clamping shell 3. When the tap 11 is placed in each clamping shell 3, the drive block has not entered the built-in hole 20. The grooved wheel 19 is not interfered with during free rotation, which facilitates the grinding of the tap 11 and improves the efficiency of manual placement.

[0025] like Figure 10 , Figure 12 , Figure 13 , Figure 14As shown, a blocking block 23 is fixedly installed inside each clamping shell 3. The blocking block 23 is located on one side of the limiting hole 7. Multiple positioning holes are evenly opened on the grinding clamping plate 2. The positioning holes are located inside the clamping shell 3 and above the blocking block 23. A fixed cylinder is rotatably installed inside the positioning hole. An electromagnet block 24 is fixedly installed at the front end of the fixed cylinder. Each electromagnet block 24 is connected to a power supply and a controller. A circular hole is opened at the front end of the electromagnet block 24. The inner diameter of the circular hole matches the outer diameter of the rear end of the tap 11. Multiple locking teeth are evenly fixed on the inner circumference of the circular hole. The number of locking teeth is set as needed. Since the rear end of the tap 11 is a square structure, the tap 1 After installation in the round hole, multiple locking teeth are locked on the edge of the tap 11, which can restrict the rotation of the tap 11. The rear end of each fixed cylinder is fixedly sleeved with a driven gear 25. The driven gear 25 is located on the rear side of the grinding chuck 2. The rear end of the grinding chuck 2 is rotatably connected with a drive gear ring 26 that meshes with each driven gear 25. The driven gear 25 is meshed with the internal teeth of the drive gear ring 26. Multiple external teeth are evenly fixed on the outer end face of the drive gear ring 26. A power gear 27 is coaxially fixedly installed on the rotating shaft of the grinding motor 14. The power gear 27 is located on the rear side of the grinding disc 15. The models of the power gear 27 and the grinding disc 15 can be replaced as needed.

[0026] like Figure 10 , Figure 12 , Figure 14 As shown, a pad 28 is fixedly installed on the top of each blocking block 23, an arc-shaped groove is opened on each clamping block 5, and multiple balls 29 are rotatably installed on the inner surface of the arc-shaped groove. A positioning cavity is opened on each electromagnet block 24 that communicates with the front and rear of the fixed cylinder. A push telescopic rod 30 is installed at the rear end of each positioning cavity. The push telescopic rod 30 is an electric telescopic rod or a pneumatic telescopic rod and is connected to a power supply and a controller. The telescopic end of the push telescopic rod 30 is set to face forward. A stabilizing frame 31 is fixedly installed at the rear end of each push telescopic rod 30. The stabilizing frame 31 is fixedly installed on the rear end of the grinding clamping plate 2. When the edge of tap 11 is being ground, the corresponding mechanism drives each sliding rod 8 to slide away from the center of the grinding clamping plate 2 along the limiting hole 7, and the return spring 10 is compressed. The sliding rod 8 drives the hinge ends of the two push rods 6 to move, so that the two moving clamping rods 4 move away from each other. The two moving clamping rods 4 open a certain distance, and tap 11 falls right between the two clamping blocks 5 and contacts the pad block 28. The pad block 28 keeps tap 11 between the two arc grooves. Then the corresponding mechanism moves away from the sliding rod 8. Due to the elasticity of the return spring 10, the two clamping blocks 5 clamp the circular surface of tap 11 through the ball 29 (the ball 29 contacts the circular surface of tap 11). Then the controller energizes each electromagnet block 24. Due to the large magnetic force, the rear end of tap 11 is instantly sucked into the circular cavity. The locking teeth engage the edge of tap 11, which limits the tap 11. The drive telescopic rod 16 pushes the sliding shell 13 to slide gradually to the right. When the grinding disc 15 contacts the edge of the tap 11, the drive telescopic rod 16 stops moving. The grinding disc 15 grinds the edge of each tap 11. At the same time, the power gear 27 meshes with the outer teeth of the drive gear ring 26 and rotates. Each driven gear 25 drives the electromagnet block 24 to rotate through the fixed cylinder. (Since the outer wall of the push telescopic rod 30 does not contact the inner wall of the fixed cylinder, the push telescopic rod 30 remains stationary.) The tap 11 will adhere to... As the ball bearing 29 rotates, the grinding chuck 2 rotates the tap 11 in a circular motion. After the tap 11 is finished being ground, the controller activates multiple telescopic rods 30 to push the rear end of the tap 11 forward until the tap 11 is completely separated from the ball bearing 29. The ground tap 11 falls into the corresponding plastic frame. Due to the multiple locking teeth limiting the tap 11, the tap 11 is always firmly in the round hole and will not rotate. This also ensures that the tap 11 is ground better and has a more refined appearance. When the tap 11 falls, it does not enter the round hole cavity due to the obstruction of the limiting teeth. When the grinding disc 15 grinds against the tap 11, the tap 11 will rotate against the ball 29 due to friction. During the rotation of the tap 11, it will correspond with the locking teeth. Due to magnetism, the tap 11 will be sucked into the round hole cavity. Multiple locking teeth limit the tap 11 again. Through the cooperation of the electromagnet block 24 and the locking teeth, the electromagnetic force can firmly attract the tap 11 into the round hole cavity, avoiding slight displacement or shaking of the tap 11 during the grinding process, thus improving the grinding accuracy. At the same time, only the grinding motor 14 is needed to realize the grinding and rotation of the tap 11, saving costs and improving work efficiency.

[0027] like Figure 4 , Figure 7 As shown, a synchronous wheel 32 is rotatably mounted on the front end of the fixed baffle 18, and a fixed shaft 33 is coaxially fixedly mounted on the front end of the synchronous wheel 32. The rear end of the grinding clamping disc 2 is rotatably mounted on the front end of the fixed shaft 33, and a fixed gear ring 34 is coaxially fixedly mounted on the rear end of the grinding clamping disc 2. An internal motor 35 is fixedly mounted on the fixed shaft 33, and an internal gear is coaxially fixedly mounted on the rotating shaft of the internal motor 35. The internal gear meshes with the fixed gear ring 34, and the internal motor 35 is connected to the controller and the power supply. When the power is turned on, the controller starts the grinding chuck 2 to rotate. The built-in gear meshes with the fixed gear ring 34 to rotate, thereby rotating the grinding chuck 2.

[0028] like Figure 4 , Figure 7As shown, a top-pressure telescopic rod 36 is fixedly installed on the front end of the equipment body 17. The top-pressure telescopic rod 36 is concentrically arranged with the grooved wheel 19. The top-pressure telescopic rod 36 is an existing spring telescopic rod. A rear friction disc 37 is coaxially fixedly installed on the telescopic end of the top-pressure telescopic rod 36. A front friction disc 38 is coaxially fixedly installed on the rear end of the grooved wheel 19. Due to the elastic force of the spring inside the top-pressure telescopic rod 36, the rear friction disc 37 and the front friction disc 38 are in close contact. Since the rear friction disc 37 is always in close contact with the front friction disc 38, the grooved wheel 19 will remain stationary after the drive block is completely moved out of the built-in hole 20, thus making the grinding clamping disc 2 rotate more precisely by one-tenth of an angle.

[0029] like Figure 2 , Figure 4 , Figure 6 , Figure 10 , Figure 11 , Figure 14 As shown, the feeding assembly includes a feeding tray 39, with a bracket fixedly installed at the lower end of the feeding tray 39. The feeding tray 39 is an existing feeding vibratory feeder. One end of the feeding tray 39 has a discharge port, and an extension box located below the discharge port is fixedly connected to one end of the feeding tray 39. The inner end of the extension box is inclined. A discharge box 40 is fixedly installed at the left end of the extension box. The discharge box 40 is inclined, and an auxiliary pressure rod 41 is fixedly installed at the top of the discharge box 40. A certain gap is provided between the auxiliary pressure rod 41 and the inner surface of the discharge box 40, allowing the tap 11 to slide freely along the gap. The auxiliary pressure rod 41 can ensure that the tap 11 slides evenly and does not accumulate. A drop opening is opened at the left end of the discharge box 40, and a stop block is detachably installed at the top of the drop opening. A guide box 42 is fixedly connected through the bottom of the drop opening. The guide box 42 is vertically connected. The feed box 40 is equipped with a trigger rod 43 fixedly installed at its rear end. The trigger rod 43 is a bent structure and is located on the rear side of the grinding clamping plate 2. The bottom end of the trigger rod 43 has a rectangular opening, and a semi-circular block is fixedly installed inside the rectangular opening. The rear end of each sliding rod 8 is fixedly installed with a trigger plate 44. The two inner ends of each clamping shell 3 are respectively fixedly provided with inclined blocks 45. The upper end of the two inclined blocks 45 is larger and the lower end is smaller to facilitate the falling of the tap 11. The auxiliary pressure rod 41 is provided with a first telescopic rod 46 and a second telescopic rod 47. The first telescopic rod 46 and the second telescopic rod 47 are electric telescopic rods and are connected to the power supply and controller. The lower end of the feed box 40 is fixedly installed with a support frame 48 for supporting the feed box 40. The bottom end of the feed box 40 is provided with a vibration motor, which is connected to the power supply and controller. Personnel feed a batch of taps 11 into the feeding tray 39 and start the feeding vibratory feeder. The feeding vibratory feeder evenly transports the taps 11 into the unloading box 40. The taps 11 in the unloading box 40 are in the following state: Figure 6As shown, the threaded end of the tap 11 is set forward, and the tap 11 slides down into the feed box 40 along the inclined surface of the extension box. A batch of taps 11 enter the feed box 40. The first telescopic rod 46 blocks the last tap 11, and the second telescopic rod 47 blocks the second to last tap 11. The shaft of the drive motor 22 rotates the swing rod 21 and the drive block. The drive block gradually enters the corresponding built-in hole 20. Due to the continuous rotation of the drive motor 22, the drive block will drive the grooved wheel 19 and the grinding clamping plate 2 to rotate. When the swing rod 21 and the built-in hole 20 are in the same vertical state, the semi-circular block on the trigger rod 43 pushes the trigger plate 44 to move upward to the highest point. At the same time, the sliding rod 8 drives the hinge ends of the two push rods 6 to move, and the return spring 10 is compressed. The two moving clamping rods 4 open quickly, and the clamping shell 3 is located directly below the guide box 42. Then the first telescopic rod 46 retracts. Since the bottom of the feeding box 40 is equipped with a vibration motor, the feeding box 40 vibrates continuously. The last tap 11 slides down through the drop hole into the guide box 42. The tap 11 falls into the clamping shell 3 below through the two inclined blocks 45 for clamping. As the drive motor 22 continues to rotate, the semicircular block on the trigger lever 43 no longer contacts the trigger plate 44. Due to the elastic force of the reset spring 10, the two moving clamping rods 4 approach each other, and the two clamping blocks 5 clamp the tap 11. Simultaneously, the first telescopic rod 46 continues to extend downwards, the second telescopic rod 47 retracts, and the tap 11 continues to slide downwards, blocked by the first telescopic rod 46. The second telescopic rod 47 then extends downwards to block the penultimate tap 11. The above steps are repeated to place taps 11 in each subsequent clamping shell 3, thus achieving automated tap placement, improving feeding efficiency, achieving the purpose of batch grinding of taps 11, and also improving safety.

[0030] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings.
