Description

Technical Field

[0002] Screws, also known as screws, are a common fastener with threads engraved on their outer surface. They are widely used in various fields. The threads on the screws are mostly rubbed out by two rubbing plates. When the rubbing plates move back and forth once, the threads are processed.

[0003] However, when processing a long screw, one end needs to be threaded so that a thread is formed on one end. However, the screw is long, and during the processing of the screw by the thread rolling plate, the other end of the screw will tilt due to its weight, which will cause the shape of the thread to be offset. If this problem cannot be effectively solved, the produced threads will all be unqualified. During the thread rolling process, burrs will remain on the processed screw threads, and metal debris will remain in the thread groove, increasing the labor intensity of manual cleaning.

DETAILED DESCRIPTION

[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of systems and methods consistent with some aspects of the present disclosure as detailed in the appended claims. Example 1

[0032] A thread rolling device with burr cleaning function for screw processing, such as Figure 1-Figure 13As shown, it includes a bottom plate 101, the front and rear sides of the upper side of the bottom plate 101 are both bolted to the first support plate 102, the rear side of the rear first support plate 102 is bolted to the control panel 103, the upper parts of the two first support plates 102 are installed with a reciprocating mechanism 104, the reciprocating mechanism 104 is electrically connected to the control panel 103, the rear side of the front first support plate 102 is bolted to the first fixing frame 105, the rear side of the first fixing frame 105 is slidably connected to a rubbing plate, and the rubbing plate on the first fixing frame 105 The plate is hinged with the reciprocating mechanism 104, and the reciprocating mechanism 104 drives the rubbing plate on the first fixed frame 105 to move up and down to rub the unprocessed screws. The second fixed frame 106 is welded to the right side of the rear first support plate 102, and the front side of the second fixed frame 106 is fixedly connected to the rubbing plate. The right part of the bottom plate 101 is provided with a feeding mechanism, which is used to feed between the two rubbing plates at intervals. The feeding mechanism ensures that only one unprocessed screw is fed each time, which improves the automation degree of the device and improves The practicability of the device is that a stabilizing mechanism is provided at the lower part of the feeding mechanism, and the stabilizing mechanism is used to support the right part of the screw. The stabilizing mechanism provides an upward supporting force for the screw being processed, so that the screw being processed remains stable as the rubbing plate moves downward, thereby avoiding the reverse deviation and broken teeth of the screw thread processed. A limit release mechanism is provided below the stabilizing mechanism, and the limit release mechanism is used to release the limit of the stabilizing mechanism on the processed screw. A burr cleaning mechanism is provided at the front part of the feeding mechanism for grinding the thread. The burr cleaning mechanism grinds the thread after processing to avoid burrs remaining on the screw thread. At the same time, the burr cleaning mechanism cleans the iron filings remaining on the screw thread to avoid iron filings remaining in the thread and reducing the quality of the screw after processing. The screw moves downward with the stabilizing mechanism, and the stabilizing mechanism supports the right part of the screw to maintain balance. The limit release mechanism contacts the limit of the stabilizing mechanism on the screw and enters the burr cleaning mechanism to grind the burrs on its thread. The feeding mechanism, the stabilizing mechanism and the burr cleaning mechanism are all electrically connected to the control panel 103.

[0033] When using the device, the operator first places the unprocessed screw on the feeding mechanism, and then the operator starts the device through the control panel 103. The control panel 103 starts the reciprocating mechanism 104, and the reciprocating mechanism 104 drives the rubbing plate on the first fixed frame 105 to move up and down reciprocatingly. At the same time, the control panel 103 starts the stabilizing mechanism and the burr cleaning mechanism. When the rubbing plate on the first fixed frame 105 moves to the upper part, the feeding mechanism pushes the lowest unprocessed screw between the two rubbing plates, and the rubbing plate on the first fixed frame 105 moves downward to rub out threads on the left end of the unprocessed screw. The feeding mechanism ensures that only one unprocessed screw is fed in each time, which improves the automation degree of the device and improves the practicality of the device. When the unprocessed screw enters between the two rubbing plates, the unprocessed screw contacts the stabilizing mechanism at the same time. The stabilizing mechanism provides an upward supporting force for the screw being processed, so that the screw being processed remains stable as the rubbing plate moves downward, avoiding the reverse deviation and broken teeth of the screw processed. At the same time, the screw being processed by the stabilizing mechanism is limited to avoid the unprocessed The screw is bent, and during the thread rolling process, the right end rotates and swings circumferentially, causing harm to the surrounding operators. After the screw is moved downward and processed, the stabilizing mechanism moves to the lower part and contacts the limit release mechanism. The limit release mechanism contacts the limit of the stabilizing mechanism on the processed screw. The limit release mechanism quickly releases the limit of the stabilizing mechanism and pushes the processed screw into the burr cleaning mechanism. Then the control panel 103 moves the stabilizing mechanism and the thread rolling plate on the first fixed frame 105 upward and resets. Then the above operation is repeated to perform thread rolling on the next unprocessed screw. The burr cleaning mechanism grinds the thread after processing to avoid burrs remaining on the screw thread, which affects the quality of the finished screw. At the same time, the burr cleaning mechanism cleans the iron filings remaining on the screw thread to avoid iron filings remaining in the thread to reduce the quality of the processed screw, and also reduces the labor intensity of subsequent manual cleaning of the thread. When all the screws are processed, the operator closes the reciprocating mechanism 104, the feeding mechanism, the stabilizing mechanism and the burr cleaning mechanism through the control panel 103 to facilitate the next use of the device.

The lower part of the spline rod 307 passes through the circular through hole 304 and presses the second support plate 406 downward. The second support plate 406 moves downward along the fourth fixed frame 402. When the second support plate 406 moves downward, the guide grooves of the two guide plates 409 make the second support plate 406 move forward first. The two guide plates 409 are respectively provided with guide grooves. The left and right sides of the second support plate 406 are slidably connected to the guide grooves of the two guide plates 409 through guide columns. The left and right parts of the fixed plate 301 are both slidably connected with sliding rods 410, and the lower ends of the two sliding rods 410 are welded with circular plates for limiting. The outer sides of the two sliding rods 410 are ring-shaped with fifth springs 411, and the upper ends of the two sliding rods 410 are welded with supporting plates 412 for pushing the screws upward. The two ends of the two fifth springs 411 are respectively fixed to the second fixed plate 301 and the supporting plate 412, and the upper side surface of the supporting plate 412 is set as a forward inclined surface. The spring force of the two fifth springs 411 is used to make the inclined surface of the supporting plate 412 push the processed screws to the front side.

[0039] like Figure 11-13As shown, the burr cleaning mechanism includes a second inclined plate 501, which is connected to the front part of the second fixed plate 301 through a mounting plate bolt, and the second inclined plate 501 is used to guide the processed screws. The front part of the upper side surface of the support frame 201 is connected to an L-shaped fixed plate 502 through a mounting plate bolt, and a gap for the screws to pass through is reserved between the L-shaped fixed plate 502 and the second inclined plate 501. The front part of the upper side surface of the support frame 201 is rotatably connected to two rotating shafts 503 through the mounting plate, and the left and right parts of the two rotating shafts 503 are both welded with rotating rollers 504, and the front and rear adjacent rotating rollers 504 are both wound with transmission belts 505, and the outer side surfaces of the two transmission belts 505 are surrounded by The two conveyor belts 505 are provided with arc grooves for placing screws. The L-shaped fixing plate 502 is located on the upper side of the two conveyor belts 505 and is used to squeeze the processed screws downward to prevent the processed screws from escaping from the arc grooves of the conveyor belts 505. The rear part of the upper side of the support frame 201 is connected to the second servo motor 506 through the mounting seat bolts. The second servo motor 506 is electrically connected to the control panel 103. The output shaft of the second servo motor 506 and the rear rotating shaft 503 are driven by the conveyor belt and the pulley. A square through hole is provided on the L-shaped fixing plate 502. The front and rear parts of the upper side of the L-shaped fixing plate 502 are rotatably connected to two electric rollers 507 through the mounting seat. The two electric rollers 507 are respectively The two motorized rollers 507 are electrically connected to the control panel 103. The two motorized rollers 507 are driven by the belt 508. The motorized roller 507 drives the belt 508 wound thereon to rotate. The lower side of the belt 508 contacts the screw moving forward. The belt 508 and the processed screw generate friction to make it rotate in the arc groove of the conveyor belt 505. The outer side of the belt 508 is provided with a rubber sheet for increasing the friction. The rubber sheet on the outer side of the belt 508 increases the friction between the processed screw and the screw, so that the screw rotates in the slide groove of the arc groove of the conveyor belt 505, avoiding the belt 508 and the processed screw from slipping. The upper side of the bottom plate 101 is bolted with a third support Plate 509, two groups of grinding rollers 510 are rotatably connected to the third support plate 509, and metal brushes for grinding are installed on the outer side of the grinding rollers 510. The grinding rollers 510 grind the burrs on the screw threads after processing to avoid residual burrs on the screw threads that reduce the quality of the finished screws. The upper and lower grinding rollers 510 are driven by gears, and the two adjacent grinding rollers 510 on the upper side are driven by conveyor belts and pulleys. The upper side of the base plate 101 is connected to the third servo motor 511 through the mounting seat bolts, and the third servo motor 511 is electrically connected to the control panel 103. The output shaft of the third servo motor 511 is driven by the grinding roller 510 at the lower rear side through a conveyor belt and a pulley.

[0040] The operator places the unprocessed screws in the silo formed by the two first inclined plates 203 and the two vertical plates 204. The unprocessed screws are arranged vertically at the lower parts of the two first inclined plates 203 and the two vertical plates 204, and the lower parts of the first inclined plates 203 and the vertical plates 204 are spaced apart by the width of a screw. The operator then starts the device through the control panel 103. The control panel 103 starts the reciprocating mechanism 104. When the reciprocating mechanism 104 drives the rubbing plate on the first fixed frame 105 to move to the uppermost part, the control panel 103 starts the pneumatic push rod 206. The telescopic rod of the pneumatic push rod 206 drives the first sliding plate 205 to move forward. The arc-shaped elastic sheet on the front side of the first sliding plate 205 is squeezed and deformed. The connecting column on the right part of the first sliding plate 205 drives the rotating wheel 212 to move forward and squeeze the wedge plate 210 downward. The wedge plate 210 moves along the third fixed frame 207. The first sliding plate 211 is reset by the control panel 103, and the vertically arranged screws move downward in sequence. At the same time, the rotating wheel 212 loses contact with the wedge plate 210, and the second sliding plate 211 is reset again under the elastic force of the first spring 209. The second sliding plate 211 is used to limit the unprocessed screw to prevent the screw from being too long and the right end of the screw from falling off the first fixed plate 202 during processing. The screw cannot enter horizontally between the two rolling plates, causing the rolled thread to deviate.

[0041] When the reciprocating mechanism 104 drives the thread rolling plate on the first fixed frame 105 to move downward, the screw being processed enters the inner side of the two arc-shaped shells 311. The inner side of the arc-shaped shell 311 is smooth, which reduces the friction on the screw being processed, avoids the resistance to the circumferentially rotating screw, and improves the thread quality of the screw after processing. The control panel 103 then starts the first servo motor 305. The output shaft of the first servo motor 305 drives the first connecting plate 303 and other components on it to move downward through the transmission gear 306 and the rack 310. The speed at which the first connecting plate 303 moves downward is the same as the speed at which the two thread rolling plates drive the screw being processed to move downward. The first connecting plate 303 drives the two arc-shaped shells 311 to support the right part of the screw being processed, so as to avoid the screw from rotating during processing. When the first connecting plate 303 drives the two arc shells 311 to move downward, the four arc tooth rings 316 respectively cooperate with the adjacent first tooth plates 317, and the four arc plates 315 slide along the arc grooves of the arc shells 311 through the sliding blocks 314. When the four arc tooth rings 316 lose engagement with the adjacent first tooth plates 317 respectively, the four third springs 313 are reset, and the four arc plates 315 are all located on the upper side of the adjacent arc shells 311. The four arc plates 315 cooperate with the adjacent arc shells 311 to limit the right part of the screw being processed to avoid bending of the screw during circumferential rotation. The circumferential swing of the right part of the screw may cause harm to the surrounding operators.

[0042] When the lower side of the first connecting plate 303 contacts the upper ends of the two limit screws 401, the screws are also processed. The first connecting plate 303 stops moving downward under the action of the two limit screws 401. The processed screws press the supporting plate 412 downward, and the supporting plate 412 and the two sliding rods 410 move downward. The two fifth springs 411 are compressed, and the first servo motor 305 drives the second connecting plate 308 and the spline rod 307 to continue to move downward. The lower part of the spline rod 307 passes through the circular through hole 304 and presses the second supporting plate 406 downward. The second spring 309 is compressed, and the second supporting plate 406 is squeezed by the spline rod 307 and moves downward along the fourth fixing frame 402. The fourth spring 405 is compressed. When the second supporting plate 406 moves downward, the guides of the two guide plates 409 The groove causes the second support plate 406 to move forward first, causing the four second tooth plates 408 on the third connecting plate 407 to move forward, so that the four second tooth plates 408 are symmetrical with the four first tooth plates 317 respectively. The second support plate 406 drives the four second tooth plates 408 to move downward, and the four second tooth plates 408 are respectively engaged with the adjacent arc-shaped toothed rings 316. The four arc-shaped toothed rings 316 respectively drive the arc plates 315 fixed thereto to rotate, so that the four arc plates 315 are rotated back to the lower part of the adjacent arc-shaped shell 311, and the four third springs 313 are compressed. Subsequently, under the action of the elastic force of the two fifth springs 411, the support plate 412 pushes the processed screw upward, and the upper side surface of the support plate 412 tilts forward, so that the processed screw moves forward and contacts the second inclined plate 501.

[0043] The control panel 103 controls the first servo motor 305 to move the first connecting plate 303 and other components on the top thereof upward and reset. First, the spline rod 307 moves upward and resets along the first connecting plate 303, the second spring 309 resets, and the second support plate 406 loses its extrusion. Under the action of the elastic force of the fourth spring 405, the second support plate 406 and the four second tooth plates 408 on the top thereof move upward and reset, and the four arc plates 315 rotate to the upper part of the adjacent arc shell 311 again, and the four third springs 313 reset. During the upward reset process of the first connecting plate 303, the four arc gear rings 316 respectively mesh with the adjacent first tooth plates 317, so that the four arc gear rings 316 rotate to the lower part of the adjacent arc shell 311 again, the four third springs 313 are compressed, and the reciprocating mechanism 104 also drives the rubbing plate on the first fixed frame 105 to move to the uppermost part, and all the above operations are repeated to process the lower unprocessed screw.

[0044] The processed screw rolls forward along the second inclined plate 501, and then enters the gap between the second inclined plate 501 and the L-shaped fixed plate 502. The control panel 103 starts the second servo motor 506. The output shaft of the second servo motor 506 is driven by the conveyor belt and the pulley to rotate the rear shaft 503. The two shafts 503 drive the conveyor belt 505 to rotate through the two rotating rollers 504 thereon. Then the processed screw enters the arc groove of the conveyor belt 505 and transmits to it. The control panel 103 starts the two electric rollers 507. The electric roller 507 drives the belt 508 wound thereon to rotate. The lower side of the belt 508 contacts the screw moving forward. The belt 508 generates friction with the processed screw to make it rotate in the arc groove of the conveyor belt 505. The rubber sheet on the outer side of the belt 508 increases the friction between the processed screw and the belt 508 to avoid the belt 508 When the screw slips after processing, the control panel 103 controls to start the third servo motor 511. The output shaft of the third servo motor 511 drives the grinding roller 510 at the lower rear side to rotate through the belt and the pulley. The two adjacent grinding rollers 510 rotate in different directions. The four grinding rollers 510 rotate at high speed so that the metal brushes thereon grind and clean the burrs generated on the screw threads to avoid the burrs remaining on the screw threads and reducing the quality of the finished screws. At the same time, the metal brushes on the four grinding rollers 510 are used to clean the iron filings remaining in the screw thread groove to avoid the iron filings remaining in the screw thread groove, thereby reducing the labor intensity of manual thread cleaning. The belt 508 makes the processed screw rotate in the arc groove of the conveyor belt 505 and cooperates with the four grinding rollers 510, so that the four grinding rollers 510 can grind and clean the screw threads after processing more comprehensively, thereby improving the practicality of the device.

[0045] When the screw processing is completed, the operator turns off the device through the control panel 103, and all the components on the device are reset and turned off, so that the device can be used next time. Example 3

[0046] On the basis of Example 2, Fig.14As shown, it also includes a thread-rubbing plate cleaning mechanism, which is arranged at the rear side of the first fixed frame 105. The thread-rubbing plate cleaning mechanism is used to grind the threads of the processed screws. The thread-rubbing plate cleaning mechanism includes a third fixed plate 601, which is bolted to the rear side of the first fixed frame 105. The upper and lower parts of the third fixed plate 601 are both circular. A slide groove is provided on the outer ring surface of the third fixed plate 601. A chain 602 is rotatably connected in the slide groove of the third fixed plate 601. A fourth servo motor 603 is bolted to the first fixed frame 105. The fourth servo motor 603 is electrically connected to the control panel 103. A sprocket 604 is keyed on the output shaft of the fourth servo motor 603. The sprocket 604 cooperates with the chain 602 to drive the chain 602. The cleaning roller 606 on the toothed plates rotates and enters between the two toothed plates, the sprocket 604 meshes with the chain 602, and the chain 602 is bolted with a fourth connecting plate 605. The right side of the fourth connecting plate 605 is welded with a cleaning roller 606 for cleaning the toothed plates, and the outer side surface of the cleaning roller 606 is circumferentially welded with a plurality of metal brushes. The metal brush on the cleaning roller 606 cleans the tooth grooves of the two toothed plates to avoid metal debris remaining in the tooth grooves of the toothed plates, which causes the thread processed by the screw to deviate and causes poor thread quality after the screw is processed. An electromagnet is installed inside the cleaning roller 606, and the electromagnet inside the cleaning roller 606 is used to absorb metal debris. The electromagnet inside the cleaning roller 606 absorbs metal iron filings, thereby improving the cleaning effect of the two toothed plates.

[0047] When the device is used up, the operator starts the fourth servo motor 603 through the control panel 103, and the output shaft of the fourth servo motor 603 drives the sprocket 604 thereon to rotate, and the sprocket 604 drives the chain 602 to slide along the slide groove of the third fixed plate 601, and the chain 602 drives the cleaning roller 606 thereon to rotate between the two rubbing plates, and the metal brush on the cleaning roller 606 is used to clean the tooth grooves of the two rubbing plates. At the same time, the electromagnet inside the cleaning roller 606 adsorbs the metal iron filings, thereby improving the cleaning effect of the two rubbing plates and avoiding the metal debris remaining in the tooth grooves of the rubbing plates, resulting in the deflection of the thread processed by the screw, resulting in poor quality of the thread after the screw is processed, and at the same time avoiding damage to the teeth of the rubbing plates. When cleaning is completed, the operator uses the control panel 103 to make the output shaft of the fourth servo motor 603 drive the chain 602 and other components on it to reset and close for the next use.
