Description

Technical Field

[0001] This invention relates to the field of oblique thread detection technology, and specifically to an oblique thread detection device for an automatic thread rolling machine. Background Technology

[0002] A thread rolling machine is a professional equipment for producing screws. The main principle of a thread rolling machine is to use a movable thread rolling plate in conjunction with a fixed thread rolling plate. When the movable thread rolling plate moves, it squeezes the screw blank and forms the screw pattern on its surface.

[0003] With the extended service life of thread rolling machines, the thread rolling plates need to be replaced. If the thread rolling plate is not perpendicular or at a proper angle to the screw axis, it can easily lead to misaligned threads on the screws. For example, if the thread rolling plate is installed at an angle, the threads will form misaligned threads in the wrong direction during the thread rolling process. Existing misaligned thread detection devices have the following technical problems in use; First, when thread rolling machines process screws, the problem of skewed threads directly affects the thread quality and assembly performance. However, the location where skewed threads form on a screw is not fixed. Skewed threads can easily appear at the front end, middle part, and rear end of the screw. Existing technology cannot detect the location where skewed threads appear on a screw, nor can it classify and collect the skewed threads from different locations.

[0004] Second, existing oblique tooth detection devices are only used to detect whether the workpiece has oblique teeth, and cannot measure the tilt angle of the thread rolling plate based on the position of the oblique teeth formed on the workpiece. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic thread rolling machine oblique tooth detection device.

[0006] The objective of this invention can be achieved through the following technical solutions: An automatic thread rolling machine skew detection device includes a worktable, on which a thread rolling machine body is mounted. The thread rolling machine body includes a front feed pipe and a rear discharge pipe. A support assembly is mounted at the rear of the worktable. A waste collection box is installed between the worktable and the support assembly. A power assembly is mounted at the bottom of the support assembly. The support assembly includes a U-shaped bracket. A detection assembly is rotatably mounted on the U-shaped bracket. The detection assembly includes a detection element driven by a three-wheeled motor. A kit assembly is mounted on the side wall of the detection element. The kit assembly includes an outer sleeve. A central shaft is mounted on the side wall of the detection element. A rotating sleeve is mounted on the side wall of the outer sleeve. The rotating sleeve slides inside the graduated groove on the U-shaped bracket on the central shaft. A workpiece groove is opened on the detection component. The workpiece processed by the thread rolling machine body enters the workpiece groove through the discharge pipe. An annular groove is opened at the front end of the workpiece groove. Two half-tooth sleeves are installed inside the annular groove. The half-tooth sleeves are connected to the inner wall of the annular groove by a spring. A guide block is installed on each half-tooth sleeve. An annular groove is opened on the side of the outer plate near the detection component. The guide block passes through the detection component and slides in the annular groove. A deep groove is opened inside the annular groove. When the guide block slides in the annular groove, the two half-tooth sleeves are joined together. When the guide block slides to the deep groove, the two half-tooth sleeves are separated under the action of the spring.

[0007] As a further aspect of the present invention: the power assembly includes a U-shaped frame, a motor is mounted on the U-shaped frame, a torque sleeve is mounted on the output end of the motor, electromagnetic chucks are mounted on both sides of the U-shaped frame, and magnetic blocks are mounted on the inner wall of the U-shaped frame; when the electromagnetic chucks are energized, they attract the magnetic blocks, thereby driving the motor to move upward, so that the torque sleeve engages with the head of the workpiece screw.

[0008] As a further aspect of the present invention: a vertical groove is formed on the outer wall of the U-shaped bracket, and a guide rod is installed on the rotating sleeve, the guide rod sliding inside the vertical groove.

[0009] As a further embodiment of the present invention: a vertical groove is formed on the outer wall of the U-shaped bracket, and a positioning groove is formed on the side of the vertical groove. A bushing is rotatably installed inside the rotating sleeve. The bushing is connected to a sliding rod through a connecting rod. The sliding rod slides inside the vertical groove. A second spring is installed on the connecting rod, and the connecting rod is connected to the rotating sleeve through the second spring.

[0010] As a further aspect of the present invention: an annular groove is formed on the central shaft, a clearance groove is formed inside the bushing, a rotating shaft is rotatably installed inside the clearance groove, a push rod is installed on the rotating shaft, the end of the push rod slides inside the annular groove, and a protrusion is installed inside the annular groove; as the central shaft rotates, the central shaft drives the protrusion to push the push rod.

[0011] As a further embodiment of the present invention: a top plate is installed on the U-shaped bracket, a guide rod is slidably installed on the top plate, a pressure sleeve is installed at the bottom of the guide rod, the pressure sleeve is connected to the top plate through a spring, and the pressure sleeve presses against the rotating sleeve.

[0012] As a further embodiment of the present invention: a second motor is installed on the side wall of the workbench, a transmission shaft is installed on the workbench, the transmission shaft is connected to the crankshaft, the second motor drives the transmission shaft and the crankshaft to rotate through a transmission belt, a crank rod is installed on the crankshaft, a movable thread rolling plate is installed at the end of the crank rod, a fixed thread rolling plate and a feeding pusher are installed on the workbench, the feeding pusher pushes the workpiece in the feed tube between the movable thread rolling plate and the fixed thread rolling plate, and the workpiece is discharged through the discharge tube.

[0013] As a further aspect of the present invention: the waste collection box includes a waste box, and the waste box is provided with a waste chamber one, a waste chamber two and a waste chamber three respectively, and the waste chamber one, waste chamber two and waste chamber three are further and further away from the support component.

[0014] The beneficial effects of this invention are: (1) In this invention, the workpiece is screwed out of the workpiece groove by motor one. If the workpiece thread section has a helical tooth, when the helical tooth on the workpiece is engaged with the two half tooth sleeves, the resistance to screwing the workpiece will inevitably increase. At this time, the torque sleeve makes a sound. After receiving the signal, motor one shuts off. The slide rod is stuck in the positioning groove under the action of spring two to prevent the rotating sleeve from moving down. Therefore, this invention tests the position of the helical tooth of the workpiece by the upward movement distance of the detection piece.

[0015] Furthermore, as motor three drives the detection piece to rotate again, the guide block slides into the deep groove. At this point, the two halves of the toothed sleeve separate under the action of spring one, causing the waste piece to detach from the workpiece groove. The inertia generated by the rotation of the detection piece propels the waste piece towards the waste bin. During this process, due to the different positions of the inclined teeth on the workpieces, the upward height of the detection piece varies. The higher the detection piece, the farther the waste piece is thrown. This process sends workpieces with different inclined tooth positions into waste chamber one, waste chamber two, and waste chamber three respectively, thus separating the waste pieces with different inclined tooth positions.

[0016] (2) Different tilt angles of the movable thread rolling plate of the present invention will result in different positions of the workpiece forming oblique teeth. If the tilt angle of the movable thread rolling plate is smaller, the oblique teeth of the workpiece will be formed at the front end of the thread section; if the tilt angle of the movable thread rolling plate is larger, the oblique teeth of the workpiece will be formed at a more rearward position. Therefore, the tilt angle of the movable thread rolling plate can be inferred from the outer sleeve plate of the present invention. Attached Figure Description

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

[0022] Please see Figures 1-14 As shown, this invention is an automatic thread rolling machine oblique tooth detection device, which includes a worktable 1, a thread rolling machine body 2 mounted on the worktable 1, the thread rolling machine body 2 including a front feed pipe 209 and a rear discharge pipe 210; a support assembly 4 is mounted at the rear of the worktable 1, a waste collection box 3 is installed between the worktable 1 and the support assembly 4, a power assembly 7 is mounted at the bottom of the support assembly 4, the support assembly 4 includes a U-shaped bracket 401, a detection assembly 5 is rotatably mounted on the U-shaped bracket 401, the detection assembly 5 includes a detection element 501, the detection element 501 is driven by a motor 8, a kit assembly 6 is mounted on the side wall of the detection element 501, the kit assembly 6 includes an outer sleeve 601, a central shaft 503 is mounted on the side wall of the detection element 501, a rotating sleeve 602 is mounted on the side wall of the outer sleeve 601, the rotating sleeve 602 is sleeved on the central shaft 503, and the rotating sleeve 602 is positioned... The workpiece slides inside the graduated groove 402 on the U-shaped bracket 401; the workpiece 502 is opened on the detection component 501, and the workpiece processed by the thread rolling machine body 2 enters the workpiece groove 502 through the discharge pipe 210. The front end of the workpiece groove 502 is opened with an annular groove 504, and two half-tooth sleeves 506 are installed inside the annular groove 504. The half-tooth sleeves 506 are connected to the inner wall of the annular groove 504 by spring 505. Guide blocks 507 are installed on each half-tooth sleeve. The outer plate 601 is opened with an annular groove 604 on the side near the detection component 5. The guide block 507 passes through the detection component 501 and slides in the annular groove 604. A deep groove 605 is opened inside the annular groove 604. When the guide block 507 slides in the annular groove 604, the two half-tooth sleeves 506 are joined together. When the guide block 507 slides to the deep groove 605, the two half-tooth sleeves 506 are separated under the action of spring 505.

[0023] Specifically, a top plate 403 is installed on the U-shaped bracket 401, a guide rod 404 is slidably installed on the top plate 403, a pressure sleeve 406 is installed at the bottom of the guide rod 404, the pressure sleeve 406 is connected to the top plate 403 by a spring 405, and the pressure sleeve 406 presses against the rotating sleeve 602. Specifically, the power assembly 7 includes a U-shaped frame 701, a motor 702 is installed on the U-shaped frame 701, a torque sleeve 703 is installed at the output end of the motor 702, electromagnetic chucks 705 are installed on both sides of the U-shaped frame 701, and magnetic blocks 704 are installed on the inner wall of the U-shaped bracket 401; when the electromagnetic chucks 705 are energized, they attract the magnetic blocks 704, thereby driving the motor 702 to move upward, so that the torque sleeve 703 engages with the head of the workpiece screw. Specifically, the waste collection box 3 includes a waste box 304, and the waste box 304 is provided with a first waste chamber 301, a second waste chamber 302 and a third waste chamber 303 respectively, and the first waste chamber 301, the second waste chamber 302 and the third waste chamber 303 are further and further away from the support component 4.

[0024] Specifically, a second motor 201 is installed on the side wall of the workbench 1, and a transmission shaft 203 is installed on the workbench 1. The transmission shaft 203 is connected to the crankshaft 204. The second motor 201 drives the transmission shaft 203 and the crankshaft 204 to rotate through the transmission belt 202. A crank rod 205 is installed on the crankshaft 204, and a movable thread rolling plate 206 is installed at the end of the crank rod 205. A fixed thread rolling plate 207 and a feeding pusher 208 are installed on the workbench 1. The feeding pusher 208 pushes the workpiece in the feed pipe 209 between the movable thread rolling plate 206 and the fixed thread rolling plate 207. The workpiece is discharged through the discharge pipe 210.

[0025] It should be noted that when the thread rolling machine body 2 is in use, the workpiece is fed into the thread rolling machine body 2 through the feed pipe 209. The motor 201 drives the transmission shaft 203 and crankshaft 204 to rotate through the transmission belt 202. The crankshaft 204 drives the movable thread rolling plate 206 to move back and forth through the crank rod 205. The movable thread rolling plate 206 squeezes the workpiece to form screws on its surface. At the same time, the feeding pusher 208 pushes the workpiece in the feed pipe 209 between the movable thread rolling plate 206 and the fixed thread rolling plate 207.

[0026] Motor 3 drives the detection component 501 to rotate. When the workpiece groove 502 on the detection component 501 approaches the discharge pipe 210, the guide block 507 slides to the deep groove 605. The two half-tooth sleeves 506 separate under the action of the spring 1 505. At this time, the workpiece processed by the thread rolling machine body 2 is sent into the workpiece groove 502 on the detection component 501 through the discharge pipe 210, so that the threaded section of the workpiece is inserted into the workpiece groove 502.

[0027] As the detection element 501 rotates, the guide block 507 slides into the annular groove 604. (See below) Figure 13 and Figure 14At this point, guide block 507 pushes the two half-tooth sleeves 506 together, connecting the half-tooth sleeves 506 to the front end of the threaded section of the workpiece. When the workpiece rotates to the bottom of the detection piece 501, see... Figure 10 and Figure 11 When the electromagnetic chuck 705 is energized, it attracts the magnetic block 704. The U-shaped frame 701 drives the motor 702 to move upward, so that the torque sleeve 703 is connected to the head of the workpiece.

[0028] At this time, motor 702 drives the workpiece to rotate. Under the action of the connection between the two half-tooth sleeves 506 and the threaded section of the workpiece, the rotation of motor 702 causes the detection piece 501 to move upward as a whole. See below. Figure 8 and Figure 9 When the detection element 501 moves upward, the detection element 501 drives the rotating sleeve 602 to move synchronously through the central shaft 503. At this time, the rotating sleeve 602 slides along the scale groove 402.

[0029] If the workpiece's threaded section has no helical teeth, motor 702 can unscrew the workpiece from the workpiece groove 502. As the electromagnetic chuck 705 is de-energized, the U-shaped frame 701 moves downward, and the workpiece falls out of the workpiece groove 502. If the workpiece's threaded section has helical teeth, the resistance to unscrewing the workpiece will inevitably increase when the helical teeth on the workpiece engage with the two half-tooth sleeves 506. At this time, the torque sleeve 703 makes a sound, and motor 702 shuts off after receiving the signal. The slide rod 606 is stuck inside the positioning groove 409 under the action of spring 607, preventing the rotating sleeve 602 from moving downward. The position of the helical teeth on the workpiece is tested by the upward movement distance of the detection element 501. If the helical teeth on the workpiece appear at the front end of the threaded section, the upward movement distance of the detection element 501 is short, and so on.

[0030] It should be noted that different tilt angles of the movable thread rolling plate 206 will result in different positions where the workpiece forms oblique teeth. If the tilt angle of the movable thread rolling plate 206 is smaller, the oblique teeth of the workpiece will form at the front end of the thread section; if the tilt angle of the movable thread rolling plate 206 is larger, the oblique teeth of the workpiece will form at a more rearward position. Therefore, the tilt angle of the movable thread rolling plate 206 can be inferred from the outer sleeve plate 601 in this invention.

[0031] As motor 3 drives the detection element 501 to rotate again, guide block 507 slides to deep groove 605. At this time, the two halves of toothed sleeve 506 separate under the action of spring 1 505, causing the waste part to detach from the workpiece groove 502. Accompanied by the inertia generated by the rotation of detection element 501, the waste part is thrown towards the waste bin 304. During this process, due to the different positions of the oblique teeth of the workpiece, the upward height of detection element 501 is different. The higher the detection element 501 is, the farther the waste part is thrown. Thus, workpieces with different oblique tooth positions are sent into waste chamber 1 301, waste chamber 2 302 and waste chamber 303 respectively, and waste parts with different oblique tooth positions are screened out.

[0032] As the detection component 501 continues to rotate, the detection component 501 pushes the push rod 611 through the protrusion 509 on the central shaft 503. The push rod 611 drives the slide rod 606 to disengage from the positioning groove 409 through the bushing 609 and the connecting rod 608, so that the kit assembly 6 and the detection assembly 5 move down and reset.

[0033] See Figures 4-9 A vertical groove 407 is provided on the outer wall of the U-shaped bracket 401, and a guide rod 603 is installed on the rotating sleeve 602. The guide rod 603 slides inside the vertical groove 407.

[0034] Specifically, a vertical groove 408 is formed on the outer wall of the U-shaped bracket 401, and a positioning groove 409 is formed on the side of the vertical groove 408. A bushing 609 is rotatably installed inside the rotating sleeve 602. The bushing 609 is connected to the sliding rod 606 through the connecting rod 608. The sliding rod 606 slides inside the vertical groove 408. A second spring 607 is installed on the connecting rod 608, and the connecting rod 608 is connected to the rotating sleeve 602 through the second spring 607.

[0035] Specifically, an annular groove 508 is formed on the central shaft 503, and a clearance groove 612 is formed inside the bushing 609. A rotating shaft 610 is rotatably installed inside the clearance groove 612, and a push rod 611 is installed on the rotating shaft 610. The end of the push rod 611 slides inside the annular groove 508, and a protrusion 509 is installed inside the annular groove 508. As the central shaft 503 rotates, the central shaft 503 drives the protrusion 509 to push the push rod 611.

[0036] It should be noted that when the detection component 501 is not moved upward, the slide rod 606 engages with the vertical groove 408. Under the action of the clearance groove 612, the protrusion 509 on the central shaft 503 pushes the push rod 611 without affecting the slide rod 606. When the detection component 501 moves upward, the slide rod 606 engages with the positioning groove 409. The slide rod 606 drives the bushing 609 to rotate through the connecting rod 608. The clearance groove 612 fits against the power end of the push rod 611. At this time, when the protrusion 509 pushes the push rod 611, the push rod 611 drives the slide rod 606 to disengage from the positioning groove 409 through the bushing 609 and the connecting rod 608, causing the kit assembly 6 and the detection assembly 5 to move downward and reset.

[0037] The implementation principle of this invention is as follows: When the thread rolling machine body 2 is in use, the workpiece is fed into the thread rolling machine body 2 through the feed pipe 209. The motor 201 drives the transmission shaft 203 and crankshaft 204 to rotate through the transmission belt 202. The crankshaft 204 drives the movable thread rolling plate 206 to move back and forth through the crank rod 205. The movable thread rolling plate 206 squeezes the workpiece to form screws on its surface. At the same time, the feeding pusher 208 pushes the workpiece in the feed pipe 209 between the movable thread rolling plate 206 and the fixed thread rolling plate 207.

[0038] Motor 3 drives the detection component 501 to rotate. When the workpiece groove 502 on the detection component 501 approaches the discharge pipe 210, the guide block 507 slides to the deep groove 605. The two half-tooth sleeves 506 separate under the action of the spring 1 505. At this time, the workpiece processed by the thread rolling machine body 2 is sent into the workpiece groove 502 on the detection component 501 through the discharge pipe 210, so that the threaded section of the workpiece is inserted into the workpiece groove 502.

[0039] As the detection element 501 rotates, the guide block 507 slides into the annular groove 604. (See below) Figure 13 and Figure 14 At this point, guide block 507 pushes the two half-tooth sleeves 506 together, connecting the half-tooth sleeves 506 to the front end of the threaded section of the workpiece. When the workpiece rotates to the bottom of the detection piece 501, see... Figure 10 and Figure 11 When the electromagnetic chuck 705 is energized, it attracts the magnetic block 704. The U-shaped frame 701 drives the motor 702 to move upward, so that the torque sleeve 703 is connected to the head of the workpiece.

[0040] At this time, motor 702 drives the workpiece to rotate. Under the action of the connection between the two half-tooth sleeves 506 and the threaded section of the workpiece, the rotation of motor 702 causes the detection piece 501 to move upward as a whole. See below. Figure 8 and Figure 9 When the detection element 501 moves upward, the detection element 501 drives the rotating sleeve 602 to move synchronously through the central shaft 503. At this time, the rotating sleeve 602 slides along the scale groove 402.

[0041] If the workpiece's threaded section has no helical teeth, motor 702 can unscrew the workpiece from the workpiece groove 502. As the electromagnetic chuck 705 is de-energized, the U-shaped frame 701 moves downward, and the workpiece falls out of the workpiece groove 502. If the workpiece's threaded section has helical teeth, the resistance to unscrewing the workpiece will inevitably increase when the helical teeth on the workpiece engage with the two half-tooth sleeves 506. At this time, the torque sleeve 703 makes a sound, and motor 702 shuts off after receiving the signal. The slide rod 606 is stuck inside the positioning groove 409 under the action of spring 607, preventing the rotating sleeve 602 from moving downward. The position of the helical teeth on the workpiece is tested by the upward movement distance of the detection element 501. If the helical teeth on the workpiece appear at the front end of the threaded section, the upward movement distance of the detection element 501 is short, and so on.

[0042] It should be noted that different tilt angles of the movable thread rolling plate 206 will result in different positions where the workpiece forms oblique teeth. If the tilt angle of the movable thread rolling plate 206 is smaller, the oblique teeth of the workpiece will form at the front end of the thread section; if the tilt angle of the movable thread rolling plate 206 is larger, the oblique teeth of the workpiece will form at a more rearward position. Therefore, the tilt angle of the movable thread rolling plate 206 can be inferred from the outer sleeve plate 601 in this invention.

[0043] As motor 3 drives the detection element 501 to rotate again, guide block 507 slides to deep groove 605. At this time, the two halves of toothed sleeve 506 separate under the action of spring 1 505, causing the waste part to detach from the workpiece groove 502. Accompanied by the inertia generated by the rotation of detection element 501, the waste part is thrown towards the waste bin 304. During this process, due to the different positions of the oblique teeth of the workpiece, the upward height of detection element 501 is different. The higher the detection element 501 is, the farther the waste part is thrown. Thus, workpieces with different oblique tooth positions are sent into waste chamber 1 301, waste chamber 2 302 and waste chamber 303 respectively, and waste parts with different oblique tooth positions are screened out.

[0044] As the detection element 501 continues to rotate, it pushes the push rod 611 via the protrusion 509 on the central shaft 503. The push rod 611, through the bushing 609 and connecting rod 608, causes the slide rod 606 to disengage from the positioning groove 409, thereby causing the kit assembly 6 and the detection assembly 5 to move down and reset. The above operation continues as the detection element 501 rotates.
