[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the present invention.

[0027] like Figure 1-8 As shown, this embodiment discloses a fastener positioning device, which is used to clamp and fix the raw material when tapping the raw material.

[0028] The fastener positioning device includes an external tapping device 100 and a workbench 200 located below the tapping device 100. The workbench 200 is located below the tapping device 100 and can perform tapping operations on the material on the positioning device. The tapping device 100 can be replaced and adjusted according to different needs.

[0029] like Figure 1As shown, a sleeve assembly 300 connected to a control module is provided on the workbench 200, and the sleeve assembly 300 includes a cylinder 1 detachably arranged on the workbench 200, the cylinder 1 is hollow and has a discharge port 2 at the upper end; a placement plate assembly 3 and a plurality of clamping members 4 distributed on the side of the placement plate assembly 3 are slidably arranged in the cylinder 1, and the placement plate assembly 3 and the clamping members 4 are both connected to a driving assembly 5, and the driving assembly 5 is connected to the control module, and is used to control the placement plate assembly 3 and the clamping members 4 to rise or fall synchronously along the cylinder 1, and at the same time control the plurality of clamping members 4 to approach each other with the placement plate assembly 3 as the center when the placement plate assembly 3 descends, and to move away from each other when the placement plate assembly 3 rises.

[0030] Among them, the control module includes an operation panel arranged on the workbench 200 and a control board connecting the drive component 5 and the power supply component 35. The control board is a PLC module, which can realize the control of the sleeve component 300, and buttons are provided on the operation panel. Through the buttons, the lifting and lowering of the placement plate component 3 can be controlled, thereby facilitating the staff to take out or place the raw materials.

[0031] like Figure 2 As shown, the workbench 200 includes a load-bearing base plate 201, to which a mesh plate 202 is connected, and a waste chamber 203 is formed between the mesh plate 202 and the load-bearing base plate 201, and waste generated by tapping can be collected in the mesh plate 202, and the mesh plate 202 is detachable relative to the load-bearing base plate 201; in order to improve the collection of tapping waste, exhaust pipes 204 connected to exhaust pumps are provided on both sides of the load-bearing base plate 201, and the exhaust pipes 204 can make the waste chamber 203 present a negative pressure, so that the waste on the mesh plate 202 can be sucked into the waste chamber 203 through the mesh holes for collection, and the mesh plate 202 only covers the top of the load-bearing base plate 201, so the staff can disassemble it at any time to facilitate the cleaning of the waste.

[0032] like Figure 2-3As shown, a sleeve assembly 300 is detachably provided on the workbench 200. The sleeve assembly 300 is connected to the workbench 200 through a mounting frame 205. The mounting frame 205 is inserted into the mesh plate 202. The sleeve assembly 300 includes a barrel 1 threadedly connected to the mounting frame 205. The barrel 1 can prevent waste from splashing during processing and facilitate the collection of raw materials. A placement disk assembly and a clamping member 4 are provided in the barrel 1. The placement disk assembly can slide up and down in the barrel 1 under the action of the driving assembly 5, thereby driving the raw materials in and out of the barrel 1, which is convenient for the staff to take and put the raw materials. There is no need to disassemble the sleeve as a whole, which improves the efficiency of raw material tapping. In addition, a number of clamping members 4 distributed around the placement disk assembly and located above it are provided in the barrel 1. The clamping members 4 can rise or fall synchronously with the placement disk assembly in the barrel 1 under the drive of the driving assembly 5, and the clamping members 4 can move away from each other during the rising process of the placement disk assembly, and can move away from each other during the falling process. Close; through the setting of the clamping member 4, after the staff places the raw material on the placing plate assembly, the clamping member 4 can clamp and position the raw material while controlling the placing plate assembly to descend, thereby ensuring that the raw material can be stably located in the center position of the placing plate assembly, and through the mutually linked placing plate assembly and the clamping member 4, the position of the raw material can be prevented from shifting during the tapping process of the tapping device 100. At the same time, since the tapping device 100 applies a downward force to the raw material during the tapping process, the clamping and fixing force on the raw material can be further improved, thereby ensuring the stability of the raw material position during the processing.

[0033] A blowing ring 6 is also provided above the clamping member 4. The blowing ring 6 is connected to an external air source (not shown in the figure) through an air pipe. When the tapping device 100 taps the raw material, the blowing ring 6 can blow air on the waste generated, thereby preventing the waste from adhering to the tapping device 100 and the raw material and affecting the processing quality. It also reduces the wear of the tapping device 100 by the waste and increases the service life of the tapping device 100.

[0034] like Figure 3-4 As shown, the placement plate assembly 3 includes a bracket 31 slidably disposed in the cylinder 1 and connected to the driving assembly 5 , and a support plate 33 coaxial with the discharge port 2 is disposed on the bracket 31 , and the support plate 33 is annular and has a diameter smaller than the discharge port 2 .

[0035] The setting of the bracket 31 can realize the fixing of the support plate 33. Figure 3As shown, the bracket 31 and the clamping member 4 are connected by an elastic telescopic rod 32, so the clamping member 4 can be driven by the driving component 5 to slide up and down along with the bracket 31. The setting of the elastic telescopic rod 32 allows the driving component 5 to allow the support plate 33 to continue to move up a distance through the bracket 31 after the clamping member 4 moves to the top of the cylinder 1. At this time, the elastic telescopic rod 32 will shrink, thereby avoiding the position of the clamping member 4 from limiting the moving distance of the support plate 33; the diameter of the support plate 33 is smaller than the discharge port 2, so the driving component 5 can allow the support plate 33 to pass through the discharge port 2 and move to the outside of the cylinder 1, which is convenient for the staff to take and put the materials, making the taking and putting of the raw materials more convenient and quick, and further improving the production efficiency.

[0036] like Figure 4 As shown, the driving assembly 5 for driving the placement plate assembly 3 is an electric lifting rod 51 arranged at the bottom of the cylinder 1, and the output end of the electric lifting rod 51 is connected to the bracket 31, so that the bracket 31 can be controlled to slide up and down in the cylinder 1.

[0037] Furthermore, when the tapping device performs a tapping operation on the raw material, the thread head 101 of the tapping will penetrate the raw material. Therefore, in order to allow the support plate 33 to adapt to thread heads 101 of different sizes and avoid damage to the support plate 33 by the thread head 101, Figure 4 , 6 As shown, the support plate 33 is composed of a number of support sheets 331 slidably arranged on the bracket 31, the support sheet 331 is fan-shaped and a notch 332 is arranged on the side of the support sheet 331 facing the center of the circle, and the notches 332 on the support sheets 331 form guide holes on the support plate 33; an abutment spring 333 is arranged between the support sheet 331 and the bracket 31, and the abutment spring 333 drives the support sheet 331 to slide toward the center of the circle.

[0038] A slide groove 334 is provided on the top of the bracket 31, and a slide rail 335 is provided on the bottom of the support piece 331. The support piece 331 is slidably connected to the bracket 31 through the slide rail 335, and an abutment spring 333 is also provided between the support piece 331 and the bracket 31, and a guide hole is provided in the center of the support plate 33; when the tapping device 100 performs tapping operation on the raw material, the thread head 101 of the tapping device 100 will first enter the guide hole after penetrating the raw material, and the inner wall of the guide hole is provided with wear-resistant material, such as ceramic, etc. During the descending process of the thread head 101, the thread head 101 will push several support pieces 331 away from each other after being inserted into the guide hole, so as to avoid the tapping device 100, so that the support plate 33 can support the raw material while avoiding damage to the support plate 33 by the tapping device 100, and the size of the support plate 33 can be adapted to raw materials of different sizes without changing the size of the support plate 33.

[0039] In order to further improve the adsorption effect of the support plate 33 on the raw material, Figure 5-6 As shown, an electromagnet 34 is disposed at the bottom of the support sheet 331 , and the electromagnet 34 is connected to a power supply assembly 35 connected to the control module.

[0040] The setting of the electromagnet 34 allows the raw material to be stably adsorbed on the support plate 33, avoiding the vibration of the support plate 33 during the tapping process, which causes the position of the raw material to shift and affects the normal processing. Among them, since the attraction of the magnet acts along the direction of the contact surface of the two objects, this vertical attraction makes separation very difficult. When the two materials slide relative to each other, there is no direct tensile force. Therefore, the electromagnet 34 is set on the support sheet 331. While attracting the raw material, it will not affect the support sheets 331 to move closer or farther away from each other. At the same time, Figure 7-8 As shown, in order to reduce the friction between the raw material and the support sheet 331, a protrusion 36 with a planar top is provided on the upper surface of the support plate 33, and the top of the protrusion 36 is used to support the raw material. The top of the protrusion 36 is planar, which can adsorb the raw material, and the setting of the protrusion 36 reduces the contact area between the raw material and the support sheet 331, thereby reducing the friction, making the sliding of the support sheet 331 smoother, and avoiding the sliding of the support sheet 331 to drive the position of the raw material to move. Although such a setting also reduces the adsorption force of the support sheet 331 on the raw material, the raw material itself does not need a large adsorption force, and the setting of the protrusion 36 can create a certain gap between the support sheet 331 and the raw material, and these gaps can provide space for the discharge of waste generated during the tapping of the raw material, so as to avoid the waste from gathering on the support plate 33 and affecting the processing accuracy.

[0041] like Figure 4-5 As shown, the electromagnet 34 is connected to the power supply assembly 35, and the staff can control the opening and closing of the electromagnet 34 at any time through the control module. The power supply assembly 35 includes a conductive track 351 arranged on the inner wall of the cylinder 1, and a conductive sheet 352 connected to the external power supply is arranged in the conductive track 351; a pair of conductive members 353 connected to the electromagnet 34 through wires are arranged on the bracket 31, and the conductive member 353 elastically abuts against the conductive sheet 352, and the conductive sheet 352 is connected to the external power supply through the wire running through the cylinder 1. The external power supply is controlled by the control module, and the guide point sheet is arranged along the path of the conductive track 351, and at the top of the conductive track 351, a power-off portion 354 that does not cover the conductive sheet 352 is arranged. When the bracket 31 is driven by the driving assembly 5 to move the support plate 33 outside the cylinder 1, at this time, the conductive member 353 on the bracket 31 is in the power-off portion 354 of the conductive track 351, so that the electromagnet 34 will lose its magnetism, so that the staff can easily take the raw materials.

[0042] like Figure 6-7As shown, the clamping member 4 includes a vertical groove 41 vertically arranged on the inner wall of the cylinder 1, and a mounting block 42 of the mounting frame 205 is slidably arranged at the opening of the vertical groove 41, and a through hole is arranged on the mounting block 42, and a connecting rod 43 connected to the driving component 5 is slidably arranged in the through hole, and a clamping block is arranged at one end of the connecting rod 43 close to the support plate 33, and the clamping block is located above the support plate 33; and the driving component 5 connected to the clamping member 4 includes a driving plate 44 arranged on the inner wall of the vertical groove 41, and an inclined driving surface is arranged on the driving plate 44, and the driving surface abuts against the connecting rod 43, and when the mounting block 42 slides downward, the driving surface drives the connecting rod 43 to slide in the direction of the support plate 33; a reset spring 45 is also arranged between the connecting rod 43 and the mounting block 42, and the reset spring 45 is used to make one end of the connecting rod 43 abut against the driving surface.

[0043] Among them, the mounting block 42 is connected to the bracket 31 of the placement disk assembly through the elastic telescopic rod 32. When the placement disk assembly descends under the drive of the driving assembly 5, the mounting block 42 slides downward along the vertical groove 41, and the inclined driving surface on the driving plate 44 abuts against the connecting rod 43. The driving surface uses the mechanical principle of the inclined surface to convert the vertical movement into the horizontal movement, pushing the connecting rod 43 to slide toward the support plate 33, thereby driving the clamping block to approach the raw material, and finally achieving the clamping and fixation of the raw material.

[0044] After the processing is completed, when the bracket 31 drives the mounting block 42 to rise, the return spring 45 takes effect, pulling the connecting rod 43 back to the initial position, so that the clamping block gradually moves away from the raw material, thereby completing the release action.

[0045] Furthermore, the driving plate 44 is slidably disposed in the vertical groove 41 and a control rod 46 is disposed between the cylinder 1, a ratchet is protruded on the driving surface, and a pawl 47 cooperating with the ratchet is disposed at one end of the connecting rod 43 facing the driving surface. Through the cooperation between the pawl 47 and the ratchet, the connecting rod 43 can move downward in one direction along the driving surface.

[0046] The ratchet on the driving surface and the pawl 47 on the connecting rod 43 cooperate with each other to achieve the limiting effect of the unidirectional movement of the connecting rod 43 during the driving process. The effect of this design is that when the driving plate 44 applies force to push the connecting rod 43 to move in the direction of the support plate 33, the pawl 47 can slide smoothly along the ratchet, so that the connecting rod 43 always remains under the control of the driving surface to complete the forward clamping action. When the driving force stops or vibration interference occurs, the meshing structure of the ratchet and the pawl 47 will form a self-locking state, preventing the connecting rod 43 from sliding in the opposite direction, ensuring that the clamping force applied by the clamping block to the raw material is continuous and stable, thereby avoiding the rebound of the clamping block or the loosening of the raw material. The self-locking mechanism of the ratchet and the pawl 47 further improves the stability and safety of the raw material clamping during the processing. Even when the equipment is vibrated or impacted, the tight meshing of the ratchet and the pawl 47 can effectively prevent the connecting rod 43 from sliding or loosening, thereby ensuring that the clamping block is always close to the raw material and ensuring the stable position of the raw material during the entire processing process.

[0047] The control rod 46 can be an electric telescopic rod or a threaded rod connected to the control module. Since the drive plate 44 slides with the vertical slot 41, the output end of the electric telescopic rod or the threaded rod is connected to the drive plate 44 to control the movement of the drive plate 44. After completing the tapping of the raw material, the staff can control the control rod 46 to move the drive plate 44 away from the connecting rod 43, thereby releasing the contact with the connecting rod 43, and then allowing the clamping member 4 to release the clamping of the raw material.

[0048] Furthermore, in order to facilitate the staff to observe the processing status of the raw materials, an observation window is also provided on the cylinder 1, and the staff can observe the processing status of the raw materials in real time through the observation window.

[0049] In order to prevent waste from splashing into the vertical groove 41 and the conductive track 351, elastically deformable rubber sleeves can be provided at the openings of the vertical groove 41 and the conductive track 351. There are two rubber sleeves in the two grooves and the length of the two rubber sleeves must be greater than or equal to the length of the two grooves. In the vertical groove 41, one end of the two rubber sleeves are respectively connected to the end of the vertical groove 41, and the other end is connected to the mounting block 42, so that when the mounting block 42 slides, the rubber sleeve can still close the opening of the vertical groove 41. The two rubber sleeves in the conductive track 351 have one end connected to the end of the conductive track 351, and the other end connected to the conductive member 353, thereby preventing waste from splashing into the groove and affecting use.

[0050] Working process During the working process, the staff first places the raw materials to be processed on the placement plate assembly, which is located in the sleeve assembly 300 and connected to the control module through the drive assembly 5. The staff controls the lifting and lowering of the placement plate assembly through the buttons on the control panel to dock with the support plate 33. The diameter of the support plate 33 is smaller than the discharge port 2, so the support plate 33 can enter the outside of the cylinder 1 through the discharge port 2, which is convenient for the staff to place the raw materials at the designated position.

[0051] When the placement disk assembly descends, the clamping member 4 descends synchronously and begins to approach the raw material. The clamping member 4 is composed of a vertical slot 41 and a mounting block 42 arranged vertically. The mounting block 42 slides in the vertical slot 41. The mounting block 42 is connected to a connecting rod 43, and the other end of the connecting rod 43 is connected to the clamping block. When the placement disk assembly descends, the mounting block 42 slides downward along the vertical slot 41, and the inclined driving surface on the driving plate 44 pushes the connecting rod 43, so that the connecting rod 43 slides toward the support plate 33, driving the clamping block to gradually approach the raw material, ensuring that the raw material is stably clamped and fixed in the center position of the placement disk. This clamping design ensures that the raw material is always kept in a stable center position during the entire tapping process through the linkage of the placement disk assembly and the clamping member 4, thereby avoiding the displacement of the raw material position and ensuring the accuracy of the tapping operation.

[0052] As the tapping device 100 is started, the tapping head applies downward pressure to tap the raw material, and the clamping member 4 provides continuous clamping force to ensure that the raw material is always stable and does not move during the tapping process. At the same time, the waste generated by the tapping operation enters the waste chamber 203 through the mesh plate 202. The waste chamber 203 is connected to the vacuum pump through the vacuum pipe 204 to maintain a negative pressure state, so that the waste is sucked into the chamber through the mesh, keeping the working area clean. The staff can easily disassemble the mesh plate 202 for cleaning to ensure that the waste in the processing process will not interfere with other operations.

[0053] During the tapping operation, the design of the support plate 33 ensures that the thread head 101 does not directly contact the support plate 33, thereby preventing the thread head 101 from damaging the support plate 33. The inner wall of the guide hole is provided with wear-resistant material, and when the thread head 101 enters the guide hole, it pushes the multiple support plates 331 away from each other, ensuring that the tapping device 100 can smoothly pass through the support plate 33 without causing damage to it.

[0054] In order to further improve the clamping force and stability of the raw material, an electromagnet 34 is installed at the bottom of the support plate 331, and the electromagnet 34 is connected to the power supply through the control module. During the tapping process, the electromagnet 34 can provide adsorption force to stably adsorb the raw material on the support plate 33 to prevent the position of the raw material from being shifted due to vibration or other external forces. When the staff needs to take out the raw material, the control module turns off the electromagnet 34, thereby releasing the adsorption force, so that the raw material can be easily taken out.

[0055] During the operation of the clamping member 4, the design of the reset spring 45 ensures that the clamping block can be quickly reset after the work is completed, and the return movement of the connecting rod 43 ensures that the clamping block is removed from the raw material, providing convenience for subsequent operations. The design of the drive plate 44 and the vertical groove 41 ensures the unidirectional movement of the connecting rod 43, and the cooperation of the ratchet and the pawl 47 provides a unidirectional movement restriction effect, ensuring that the connecting rod 43 will not slide in the opposite direction, thereby enhancing the stability and continuity of the clamping force.

[0056] The entire device is automated through the PLC control module. The staff only needs to control the lifting and lowering of each component and the opening and closing of the electromagnet 34 through the buttons on the control panel to complete the clamping, tapping and waste collection of the raw materials. The coordinated work of each component improves production efficiency and processing accuracy, reduces manual intervention and operation steps, and makes the raw material processing process more efficient, accurate and stable.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
