Description

Technical Field

[0001] The invention relates to the technical field of automatic screw locking machines, in particular to a screw locking mechanism and an automatic screw locking machine. Background Art

[0002] In the manufacturing process of mechanical equipment, it is often necessary to tighten the screws on parts. The traditional manual screw tightening has been gradually replaced by automatic screw locking machines. Compared with manual work, automatic screw locking machines have stable operation and high efficiency, and can reduce the instability caused by manual errors. Automatic screw locking machines are divided into handheld screw locking machines, multi-axis automatic screw locking machines and coordinate automatic screw locking machines.

[0003] However, when the existing automatic screw locking machines are used to lock screws on different workpieces, since the position of the screw bit is often fixed, it is necessary to perform cumbersome targeted adjustments to the position of the screw bit, which is cumbersome to operate. At the same time, different screw hole positions on the same workpiece may have inconsistent heights. When locking the screws, especially when the workpiece is not fixed in place, if the screw bit contacts the workpiece inconsistently, the position of the workpiece may be offset.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figure 1As shown in the figure, a screw locking mechanism according to the present invention includes a base 1. A direction adjusting structure 2 is provided on the top side of the base 1. A fixed-length structure 3 is provided inside the direction adjusting structure 2. The direction adjusting structure 2 is connected to an adjusting structure 7. The end of the fixed-length structure 3 is connected to a locking structure 5. A lifting structure 4 is connected between the base 1 and the direction adjusting structure 2. A fixing structure 6 is installed on the base 1.

[0042] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.11 As shown in the figure, the direction adjusting structure 2 includes a lifting seat 201. The lifting seat 201 is provided on the top side of the base 1. The lifting seat 201 has a "U" - shaped structure. Two direction adjusting blocks 202 are rotatably connected to both sides of the lifting seat 201. A worm gear 205 is rotatably connected to the top side of the direction adjusting block 202. A worm 204 is meshed with the side of the worm gear 205. The worm 204 is rotatably connected to the lifting seat 201. A release block 206 is slidably connected inside the direction adjusting block 202. A first engaging block 207 is provided at each end of the release block 206. A second elastic member 210 is fixedly connected between the release block 206 and the direction adjusting block 202. A plurality of engaging grooves 209 are formed inside the worm gear 205. The top end of the first engaging block 207 is engaged with the worm gear 205 through the engaging groove 209. The first engaging block 207 is slidably connected to the release block 206. A first elastic member 208 is fixedly connected between the first engaging block 207 and the release block 206. The top end of the first engaging block 207 has a hemispherical structure. An extrusion block 203 is slidably connected to the top side of the lifting seat 201;

[0043] The direction adjustment block 202 located inside the lifting seat 201 is used to adjust the direction according to the position of the screw hole on the workpiece to ensure that the screw head 506 can be aligned with the screw hole of the workpiece. The user can first press the corresponding extrusion block 203 located on the top of the lifting seat 201, so that the extrusion block 203 pushes the release block 206 to slide to the bottom side. At this time, the top part of the first engaging block 207 is separated from the engaging groove 209 provided on the worm gear 205, and only the top side hemispherical structure part of the first engaging block 207 is retained. The engaging groove 209 acts as a positioning effect. At this time, the user can directly rotate the adjustment block 202 to roughly adjust the direction, and then release the extrusion block 203. At this time, the release block 206 rises, and at the same time, the first engaging blocks 207 at both ends of the release block 206 re-engage with the engaging groove 209 on the inner side of the worm gear 205. At this time, the direction of the adjustment block 202 can be finely adjusted by rotating the worm 204 meshing with it, ensuring that the screw head 506 can be aligned with the corresponding screw hole on the workpiece.

[0044] Specifically, Figure 1 , Figure 3 , Figure 5 As shown, the fixed length structure 3 includes an adjustment block 303, the inner side of the adjustment block 202 is slidably connected with the adjustment block 303, the bottom side of the adjustment block 303 is provided with a threaded groove 305, the bottom side of the adjustment block 202 is rotatably connected with a first screw rod 302, the first screw rod 302 is threadedly connected to the adjustment block 303 through the threaded groove 305, the inner side of the adjustment block 303 is slidably connected with a mounting arm 301, the inner side of the mounting arm 301 is provided with a toothed groove 307, the middle part of the adjustment block 303 is slidably connected with the second engaging block 304, the second engaging block 304 and the adjustment block 303 are fixedly connected with a third elastic member 306, the second engaging block 304 is engaged with the mounting arm 301 through the toothed groove 307, the top side of the second engaging block 304 is in contact with a pushing rod 308, the pushing rod 308 is slidably connected with the release block 206, and the top end of the pushing rod 308 is in contact with the extrusion block 203;

[0045] After the angle adjustment of the steering block 202 is completed, the position of the mounting arm 301 needs to be adjusted. The structure for locking the screw is located at the end of the mounting arm 301. For easy operation, when the user presses the squeezing block 203 located on the top side of the lifting seat 201, the release block 206 and the pushing rod 308 in the middle of the release block 206 will slide downward at the same time. When the pushing rod 308 slides to the bottom side, the end of the pushing rod 308 will push the second engaging block 304 that conflicts with it. After the second engaging block 304 slides under force, the extended parts on both sides of the second engaging block 304 will release the engagement with the toothed groove 303 on the inner side of the mounting arm 301. 07 is in the engaged state, that is, at this time the user can freely adjust the telescopic length and orientation angle of the mounting arm 301 and the steering block 202. After completing the telescopic length between the mounting arm 301 and the steering block 202 and the approximate angle adjustment of the steering block 202, the position of the mounting arm 301 can be fine-tuned by rotating the worm 204 and the first screw 302 in turn. The first screw 302 can drive the adjustment block 303 to slide in a small range on the inner side of the steering block 202 through the threaded groove 305, so as to complete the fine-tuning of the telescopic distance of the mounting arm 301 and improve the efficiency of the preparation work.

[0046] Specifically, Figure 2 , Figure 3 , Figure 8 , Fig. 9 , Fig.10 As shown, the adjustment structure 7 includes an adjustment rod 701, and the two sides of the lifting seat 201 are respectively slidably connected with an adjustment rod 701, and the two worms 204 arranged on the same side are respectively slidably connected to the two sides of the adjustment rod 701, and the ends of the worms 204 are provided with connecting grooves 709. The adjustment rod 701 is slidably connected with a driving sleeve 706, and the end of the driving sleeve 706 is slidably connected with the worm 204 through the connecting groove 709. A ninth elastic member 708 is fixedly connected between the driving sleeve 706 and the adjustment rod 701, and the side of the adjustment rod 701 is fixed with a ninth elastic member 708. The surface is fixedly connected with a slide column 707, the middle part of the driving sleeve 706 is in conflict with the slide column 707, the middle part of the adjusting rod 701 is rotatably connected with a calibration block 702, the calibration block 702 is slidably connected with the lifting seat 201, and three conflict grooves 704 are respectively provided on both sides of the lifting seat 201, the middle part of the calibration block 702 is slidably connected with a contact head 703, an eighth elastic member 705 is fixedly connected between the contact head 703 and the calibration block 702, and the top of the contact head 703 is in conflict with the lifting seat 201 through the conflict groove 704;

[0047] Since the screw holes on some workpieces are symmetrically arranged, in order to improve the processing efficiency of such workpieces, when adjusting the position of the mounting arm 301, the user can slide the adjusting rod 701 located on the side of the lifting seat 201, so that the contact head 703 on the calibration block 702 in the middle of the adjusting rod 701 conflicts with the contact groove 704 in the middle. At this time, the ends of the driving sleeves 706 at both ends of the adjusting rod 701 will cooperate with the connecting groove 709 at the end of the worm 204 set on the same side, that is, when the adjusting rod 701 is rotated at this time, the adjusting rod 701 can simultaneously drive the direction adjustment blocks 202 on both sides to rotate, so that To ensure that the rotation angles of the steering blocks 202 on both sides remain consistent and improve the adjustment accuracy and efficiency, when it is necessary to drive the worm 204 on one side alone, the user only needs to slide the adjustment rod 701 to make the contact head 703 slide into the contact groove 704 on the corresponding side. At this time, with the subsequent rotation of the adjustment rod 701, the drive sleeve 706 will slide into the connecting groove 709 of the corresponding worm 204 under the push of the ninth elastic member 708, and the drive sleeve 706 on the other side will be detached from the corresponding worm 204 under the traction of the sliding column 707, thereby realizing the adjustment of the angle of the single-sided steering block 202.

[0048] Specifically, Figure 1 , Figure 2 , Figure 4 , Fig.11 As shown, the locking structure 5 includes a motor 501, the end of the mounting arm 301 is mounted with the motor 501, the end of the motor 501 is fixedly connected with a drive shaft 504 through a coupling, the bottom side of the mounting arm 301 is vertically fixedly connected with a threaded sleeve 502, the drive shaft 504 is arranged inside the threaded sleeve 502, a telescopic rod 505 is slidably connected to the drive shaft 504, an adjusting sleeve 503 is rotatably connected to the telescopic rod 505, the adjusting sleeve 503 is threadedly connected to the outer side of the threaded sleeve 502, a screwdriver bit 506 is slidably connected to the bottom end of the telescopic rod 505, and a fourth elastic member 507 is fixedly connected between the screwdriver bit 506 and the telescopic rod 505;

[0049] A driving shaft 504 is provided at the bottom side of the end of the mounting arm 301. After the motor 501 on the top side of the mounting arm 301 is electrically connected to an external power supply, the corresponding driving shaft 504 can be driven to rotate by the motor 501. The driving shaft 504 can drive the screw bit 506 to rotate through the telescopic rod 505 on the bottom side to achieve the locking of the screw. When there is a height difference between the screw holes on the workpiece, the user can rotate the adjusting sleeve 503 according to the height of the screw hole. The rotation of the adjusting sleeve 503 can drive the telescopic rod 505 to change its height, and finally the screw bit 506 is located at the height corresponding to the screw hole on the workpiece, thereby ensuring that the screw bit 506 can apply the same force to the screw, thereby ensuring the quality of processing.

[0050] Specifically, Figure 1 , Figure 2 , Figure 7 , Fig.11 As shown, the lifting structure 4 includes a hydraulic rod 401, the hydraulic rod 401 is installed on the lifting seat 201, the end of the hydraulic rod 401 is fixedly connected to the base 1, the two sides of the lifting seat 201 are respectively fixedly connected with guide grooves 403, the two sides of the base 1 are respectively fixed with guide grooves 403, and two connecting rods 402 arranged in an "X" shape are arranged between the two guide grooves 403 arranged up and down on the same side, the middle parts of the two connecting rods 402 are rotatably connected, one end of the connecting rod 402 is rotatably connected to the guide groove 403, and the other end of the connecting rod 402 is slidably connected to the guide groove 403 on the other side;

[0051] A hydraulic rod 401 is installed on the lifting seat 201, and the end of the hydraulic rod 401 is connected to the base 1. The hydraulic rod 401 can drive the lifting seat 201 to move up and down in height, so as to lock the screws through the screwdriver 506. At the same time, in order to ensure the stability of the lifting seat 201 during the lifting process, two cross-arranged connecting rods 402 are connected between the lifting seat 201 and the base 1. One end of the connecting rod 402 is rotatably connected to the corresponding guide groove 403, and the other end is slidably connected to the guide groove 403, thereby ensuring that the lifting seat 201 remains in a horizontal state during the lifting process, thereby improving the processing quality and the stability of the device.

[0052] Specifically, Figure 1 , Figure 7 , Fig.11 , Fig.12 , Fig.13 , Fig.14As shown, the fixed structure 6 includes a feeding plate 601, the feeding plate 601 is rotatably connected to the base 1, a positioning groove 613 is provided on the bottom side of the feeding plate 601, a positioning block 612 is slidably connected to the inner side of the base 1, a seventh elastic member 614 is fixedly connected between the positioning block 612 and the base 1, the top of the positioning block 612 is in conflict with the feeding plate 601 through the positioning groove 613, a cam 602 is fixedly connected to the middle part of the base 1, and a bearing plate 603 is slidably connected to both sides of the feeding plate 601, a sixth elastic member 611 is fixedly connected between the bearing plate 603 and the feeding plate 601, the side of the feeding plate 601 is in conflict with the cam 602, and the bearing plate The top side of 603 is rotatably connected to a control rod 605, the end of the control rod 605 is fixedly connected to a first bevel gear 608, the side of the first bevel gear 608 is meshed with a second bevel gear 609, the middle of the second bevel gear 609 is fixedly connected to a second screw 610, the second screw 610 is rotatably connected to the carrier plate 603, a push plate 604 is slidably connected to the carrier plate 603, the push plate 604 is threadedly connected to the second screw 610, the two ends of the feed plate 601 are respectively slidably connected to a fastening block 606, a fifth elastic member 607 is fixedly connected between the fastening block 606 and the feed plate 601, and the fastening block 606 is slidably connected to the top side of the carrier plate 603;

[0053] After completing the adjustment of the device, the user needs to place the workpiece to be processed in the middle position of the carrying plate 603, and use the automatic nail feeding machine to feed the screws into the screw holes of the workpiece. By rotating the feeding plate 601, the workpiece can be rotated to the bottom of the locking structure 5. When the feeding plate 601 rotates, a positioning block 612 and a positioning groove 613 for rotation positioning are provided on the bottom side. Since the adjustment of the position of the screwdriver bit 506 is completed, after lowering the lifting seat 201, the screwdriver bit 506 can be accurately inserted into the screw hole of the workpiece, and then the locking work of the screw is completed through the driving effect of the motor 501. In this process, in order to ensure a good fixing effect on the workpiece and avoid the workpiece from deviating during the processing, a pushing plate 604 is provided on the carrying plate 603. When the user places the workpiece on the carrying plate 603, the corresponding control rod 605 can be rotated to The transmission effect of the gear 609 can drive the second screw 610 to rotate, and then adjust the position of the pushing plate 604 until the side of the workpiece is pushed to contact with the fastening block 606. After completing the corresponding adjustment work, the feeding plate 601 is rotated. Due to the cam 602 set in the middle of the feeding plate 601, the supporting plate 603 located on the inner side of the device will be pushed to one side by the cam 602. At this time, the fastening block 606 connected with the fifth elastic member 607 can cooperate with the pushing plate 604 to clamp and fix different types of workpieces to ensure the stability of the workpiece during processing. After the processing is completed, with the loss of the resistance effect of the cam 602 on the supporting plate 603, the clamping effect on the workpiece disappears, which facilitates the removal of the workpiece. On the other hand, through the setting of the rotatable feeding plate 601, one side can place the next workpiece while the workpiece screw is being locked, thereby improving the processing efficiency.

[0054] In addition, the present invention also provides an automatic screw locking machine, including an automatic nail feeding machine, a positioning fixture, a detection mechanism, an automatic unloading mechanism, and the screw locking mechanism as described above, wherein the automatic nail feeding machine is used to transmit screws to the fixed product screw holes, the positioning fixture is used to position the product, the detection mechanism includes a CCD camera, the CCD camera is used to detect whether the screw locking mechanism has completed the screw locking, and the automatic unloading mechanism is used to take out the product. The specific structure of the automatic screw locking machine refers to the above embodiment. Since the automatic screw locking machine adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0055] When the present invention is in use, first, the direction adjustment block 202 located inside the lifting seat 201 is used to adjust the direction according to the position of the screw hole on the workpiece to ensure that the screw head 506 can be aligned with the screw hole position of the workpiece. The user can first press the corresponding extrusion block 203 located on the top of the lifting seat 201, so that the extrusion block 203 pushes the release block 206 to slide to the bottom side. At this time, the top part of the first engaging block 207 is separated from the engaging groove 209 provided on the worm gear 205, and only the top hemispherical structure part of the first engaging block 207 is retained in the engaging groove 209, which serves as a positioning effect. At this time, the user can directly rotate the direction adjustment block 202 to make a rough adjustment of the direction, and then release the extrusion block 203. At this time, the release block 206 rises and the release block 206 is released. The first engaging blocks 207 at both ends of 206 engage with the engaging grooves 209 on the inner side of the worm gear 205 again. At this time, the direction of the adjustment block 202 can be finely adjusted by rotating the worm 204 meshing therewith, so as to ensure that the screw head 506 can be aligned with the corresponding screw hole on the workpiece. After completing the angle adjustment of the adjustment block 202, the position of the mounting arm 301 needs to be adjusted. The structure for locking the screw is located at the end of the mounting arm 301. For the convenience of operation, when the user presses the squeezing block 203 located on the top side of the lifting seat 201, the release block 206 and the pushing rod 308 in the middle of the release block 206 will slide downward at the same time. When the pushing rod 308 slides toward the bottom side, the end of the pushing rod 308 will push the second engaging block that conflicts with it. The second engaging block 304 slides under the force, and the extension parts on both sides thereof will release the engaging state with the toothed groove 307 on the inner side of the mounting arm 301, that is, at this time, the user can freely adjust the telescopic length and the orientation angle of the mounting arm 301 and the steering block 202. After completing the telescopic length between the mounting arm 301 and the steering block 202 and the approximate angle adjustment of the steering block 202, the position of the mounting arm 301 can be fine-tuned by rotating the worm 204 and the first screw 302 in turn. The first screw 302 can drive the adjustment block 303 to slide in a small range on the inner side of the steering block 202 through the threaded groove 305, so as to complete the fine-tuning of the telescopic distance of the mounting arm 301, thereby improving the efficiency of the preparation work. The screw holes on the adjusting rod 701 are symmetrically arranged. In order to improve the processing efficiency of such workpieces, when adjusting the position of the mounting arm 301, the user can slide the adjusting rod 701 located on the side of the lifting seat 201, so that the contact head 703 on the calibration block 702 in the middle of the adjusting rod 701 conflicts with the contact groove 704 in the middle. At this time, the ends of the driving sleeves 706 at both ends of the adjusting rod 701 will cooperate with the connecting grooves 709 at the ends of the worm 204 arranged on the same side. That is, when the adjusting rod 701 is rotated at this time, the adjusting rod 701 can simultaneously drive the direction adjustment blocks 202 on both sides to rotate, thereby ensuring that the rotation angles of the direction adjustment blocks 202 on both sides are consistent, thereby improving the adjustment accuracy and efficiency. When the worm 204 on one side needs to be driven separately,The user only needs to slide the adjustment rod 701 to make the contact head 703 slide into the contact groove 704 on the corresponding side. At this time, with the subsequent rotation of the adjustment rod 701, the drive sleeve 706 will slide into the connecting groove 709 of the corresponding worm gear 204 under the push of the ninth elastic member 708, and the drive sleeve 706 on the other side will be separated from the corresponding worm gear 204 under the traction of the sliding column 707, so as to adjust the angle of the unilateral adjustment block 202. A drive shaft 504 is provided at the bottom side of the end of the mounting arm 301. After the motor 501 on the top side of the mounting arm 301 is electrically connected to the external power supply, the corresponding drive shaft 504 can be driven to rotate by the motor 501, and the drive shaft 504 can drive the screwdriver 506 to move forward through the telescopic rod 505 on the bottom side. The screw can be locked by rotating the adjusting sleeve 503, and when there is a height difference between the screw holes on the workpiece, the user can rotate the adjusting sleeve 503 according to the height of the screw holes. The rotation of the adjusting sleeve 503 can drive the telescopic rod 505 to change the height, and finally the screw bit 506 is located at the height corresponding to the screw hole on the workpiece, so as to ensure that the screw bit 506 can apply the same force to the screw, and the processing quality is guaranteed. A hydraulic rod 401 is installed on the lifting seat 201, and the end of the hydraulic rod 401 is connected to the base 1. The lifting seat 201 can be driven to rise and fall in height by the hydraulic rod 401, so as to lock the screw through the screw bit 506. At the same time, in order to ensure the stability of the lifting seat 201 during the lifting process, the lifting seat 201 and the base 1 are connected. Two cross-arranged connecting rods 402 are connected in between, one end of the connecting rod 402 is rotatably connected to the corresponding guide groove 403, and the other end is slidably connected to the guide groove 403, so as to ensure that the lifting seat 201 maintains a horizontal state during the lifting process, improve the processing quality and the stability of the device. After completing the adjustment of the device, the user needs to place the workpiece to be processed in the middle position of the carrier plate 603, and use the automatic nail feeding machine to feed the screws into the screw holes of the workpiece. By rotating the feeding plate 601, the workpiece can be rotated to the bottom of the locking structure 5. When the feeding plate 601 rotates, a positioning block 612 and a positioning groove 613 for rotation positioning are provided on the bottom side. Since the adjustment of the position of the screwdriver bit 506 is completed, after lowering the lifting seat 201, the screwdriver bit 506 can be accurately inserted into the screw hole of the workpiece, and then the locking work of the screw is completed through the driving effect of the motor 501. In this process, in order to ensure a good fixing effect on the workpiece and avoid the workpiece from shifting during the processing, a pushing plate 604 is provided on the carrier plate 603. When the user places the workpiece on the carrier plate 603, the corresponding control rod 605 can be rotated, and the transmission effect of the first bevel gear 608 and the second bevel gear 609 can drive the second screw 610 to rotate, thereby adjusting the position of the pushing plate 604 until the side of the workpiece is pushed to contact with the fastening block 606. After completing the corresponding adjustment work, the feeding plate 601 is rotated. Due to the cam 602 set in the middle of the feeding plate 601,The carrier plate 603 located inside the device will be pushed to one side by the cam 602. At this time, the fastening block 606 connected with the fifth elastic member 607 cooperates with the push plate 604 to clamp and fix different types of workpieces, ensuring the stability of the workpiece during processing. After the processing is completed, as the cam 602 loses its resistance effect on the carrier plate 603, the clamping effect on the workpiece disappears, making it convenient to take out the workpiece. On the other hand, through the setting of the rotatable feeding plate 601, one side can place the next workpiece while the workpiece screws are being locked, thereby improving the processing efficiency.
