Description

Technical Field

[0001] The invention relates to the technical field of clamping devices, in particular to an auxiliary positioning clamping device for processing threaded fasteners. Background Art

[0002] A clamping device is a mechanical device used to fix or hold a workpiece in place during processing. Clamping devices are widely used in machine tools, automated production lines, assembly processes, etc. to ensure the position accuracy and stability of the workpiece during operation.

[0003] For example, for the clamping of bolts, the burrs on the surface of the bolts need to be removed during the processing. A clamping device must be used during the processing to fix the bolts so that the next step of processing can be carried out. Chinese patent CN208880211U discloses a clamping device for bolt processing, in which the two opposite ends of the two sliding bars are fixedly connected to an arc plate, and the opposite sides of the two movable plates are movably connected to a first movable bar, one end of the first movable bar is movably connected to a cross plate, and the other side of the cross plate is movably connected to a second movable bar, an end of the second movable bar away from the cross plate is movably connected to one side of the arc plate, and a first spring is fixedly connected between the opposite sides of the first movable bar and the second movable bar, a second spring is fixedly connected between the surface of the sliding bar and one side of the movable plate and one side of the arc plate, teeth are fixedly connected between the opposite sides of the two arc plates, a vertical plate is fixedly connected to the back of the top of the workbench, and a hydraulic telescopic rod is fixedly connected to the front of the vertical plate to clamp and fix the bolts.

[0004] However, when the bolt is clamped in the above scheme, the thread on the bolt surface is easily damaged. If the clamping force is small, good stability cannot be maintained, thereby affecting the processing quality of the bolt during the processing. Summary of the invention

[0005] Based on this, it is necessary to provide an auxiliary positioning and clamping device for processing threaded fasteners to address the problem of poor bolt clamping effect at present.

[0006] The above purpose is achieved through the following technical solutions:

[0007] An auxiliary positioning and clamping device for processing threaded fasteners, comprising:

[0008] A workbench, wherein a stop hole is provided on the workbench, one end of the threaded fastener is located in the stop hole, and the threaded fastener and the workbench are relatively stationary;

[0009] A clamping frame, the clamping frame is fixedly arranged on the workbench, a plurality of clamping plates are distributed on the side wall of the clamping frame in the vertical direction, the plurality of clamping plates can move along the radial direction of the threaded fastener to clamp the threaded fastener, a locking thread is arranged on one end of the clamping plate close to the threaded fastener, and the locking thread can be adapted to the thread of the threaded fastener;

[0010] The auxiliary clamping assembly can completely lock and match the locking threads of multiple clamping plates with the threads of the threaded fastener.

[0011] Furthermore, the auxiliary clamping assembly includes a vertical push frame and a rotating push frame. The vertical push frame is telescopically arranged on the workbench, and the vertical push frame connects multiple clamping plates away from one end of the threaded fastener. The reciprocating movement of the vertical push frame can drive the multiple clamping plates close to one end of the threaded fastener to reciprocate in the vertical direction. The rotating push frame is rotatably connected to the workbench, and the rotation of the rotating push frame drives the vertical push frame to rotate, and the vertical push frame drives the multiple clamping plates to rotate circumferentially around the threaded fastener.

[0012] Furthermore, the vertical push frame is provided with a sliding groove extending along the circumference of the threaded fastener, and there are multiple sliding grooves, which are arranged in the vertical direction. A slider is slidably arranged in the sliding groove, and the slider is hinged to the end of the clamping plate away from the threaded fastener. The clamping plate can rotate in the vertical direction around the hinge position, and abutment components are provided on the two ends of the sliding groove, and the abutment components can abut the clamping plate to lock the threaded fastener.

[0013] Furthermore, the abutment assembly includes an elastic member and an abutment plate, one end of the elastic member is fixedly connected to the end of the slide groove, and the other end of the elastic member is fixedly connected to the abutment plate, and the abutment plate abuts the slider. During the rotation of the vertical frame, the clamping plate rotates relative to the threaded fastener, and the threaded fastener moves away from the clamping plate. After the locking thread on the clamping plate is fully matched with the thread of the threaded fastener, the abutment plate rotates relative to the slide groove to compress the elastic member.

[0014] Furthermore, the elastic member is a spring.

[0015] Further, a sliding plate is provided at the bottom of the vertical push frame, and the sliding plate can move around the circumference of the threaded fastener on the workbench and can move along the radial direction of the threaded fastener. The vertical push frame has a telescopic part, and the telescopic part of the vertical push frame is provided with a first telescopic member, and the telescopic movement of the first telescopic member can drive the vertical push frame to reciprocate in the vertical direction;

[0016] A second telescopic member is fixedly arranged on the workbench and distributed along the circumferential direction of the threaded fastener. One end of the second telescopic member is fixedly connected to the workbench, and the other end of the second telescopic member abuts against the side wall of the vertical push frame. The telescopic movement of the second telescopic member drives the vertical push frame to rotate along the circumferential direction of the threaded fastener.

[0017] Furthermore, a third telescopic member distributed radially along the threaded fastener is arranged on the workbench, one end of the third telescopic member is fixedly connected to the workbench, and the other end of the third telescopic member abuts against the vertical push frame.

[0018] Furthermore, the third telescopic member is fixedly connected with an arc plate on one end of the vertical push frame, and the arc plate is adapted to the vertical push frame.

[0019] Furthermore, an annular slide rail is provided on the workbench, a sliding protrusion is provided at the bottom of the sliding plate, the sliding protrusion is slidably arranged in the annular slide rail, and the width of the annular slide rail is greater than the sliding protrusion.

[0020] Furthermore, there are two of the second telescopic members and the third telescopic members.

[0021] The beneficial effects of the present invention are:

[0022] The present invention provides a locking thread on a clamping plate, and the clamping plate has one end with the locking thread to clamp the threaded fastener, so that the locking thread cooperates with the thread on the outer periphery of the threaded fastener. When the clamping plate clamps the threaded fastener, the locking thread on the clamping plate cooperates with the thread on the outer periphery of the threaded fastener, thereby preventing the clamping force of the clamping plate from being too large to damage the thread on the outer periphery of the threaded fastener. In addition, there are multiple clamping plates, which can evenly clamp the threaded fastener.

[0023] The present invention provides an auxiliary clamping assembly on the workbench, which can fully match the locking thread on the clamping plate with the thread on the outer periphery of the threaded fastener, thereby avoiding the locking thread on the clamping plate not being fully matched with the thread on the outer periphery of the threaded fastener. When the locking thread and the outer thread of the threaded locking piece are fully matched, the degree of damage to the thread on the outer periphery of the threaded fastener is extremely small when a large clamping force is used, and the threaded locking piece can be further locked by rotating the clamping plate around the threaded fastener, thereby improving the clamping effect of the threaded fastener.

[0036] Refer to the following Figure 1-Figure 5 The auxiliary positioning and clamping device for processing threaded fasteners provided by the present invention is described.

[0037] An auxiliary positioning and clamping device for processing threaded fasteners is suitable for auxiliary positioning and clamping of threaded fasteners 300, including a workbench 100. A stop hole 110 is provided on the workbench 100. The stop hole 110 is used to limit the rotation of the threaded fastener 300. The stop hole 110 in this embodiment is in the shape of a regular hexagon. The threaded fastener 300 in this embodiment is a bolt. The hexagonal head on the bolt can be restricted from rotating when it is located in the stop hole 110. The stop hole 110 only limits the rotation of the threaded fastener 300. To fully clamp it, a clamping frame 120 needs to be provided on the workbench 100. The clamping frame 120 of the present invention surrounds the outer periphery of the threaded fastener 300. Figure 1 As shown, a plurality of through slots 130 arranged in a vertical direction are provided on the side wall of the clamping frame 120, and a clamping plate 150 is slidably arranged in each through slot 130. The clamping plate 150 is placed horizontally, and the clamping plate 150 can move radially along the threaded fastener 300 in the through slot 130. The clamping plate 150 in the prior art can move toward the direction close to the threaded fastener 300 to clamp the threaded fastener 300, but when the clamping force is too large, the threads on the outer periphery of the threaded fastener 300 are easily damaged, and when the clamping force is small, the threaded fastener 300 cannot be clamped, resulting in a poor clamping effect of the threaded fastener 300.

[0038] The present invention provides a semi-arc groove on one end of the clamping plate 150 close to the threaded fastener 300, and a locking thread 160 is arranged on the inner periphery of the semi-arc groove, and the locking thread 160 matches the thread on the outer periphery of the threaded fastener 300, so that when the clamping plate 150 clamps the threaded fastener 300, the locking thread 160 on the clamping plate 150 matches with the thread on the outer periphery of the threaded fastener 300, thereby preventing the clamping force of the clamping plate 150 from being too large to damage the thread on the outer periphery of the threaded fastener 300, and the clamping plate 150 has multiple , which can evenly clamp the threaded fastener 300. At the same time, an auxiliary clamping assembly is arranged on the workbench 100. The auxiliary clamping assembly can fully match the locking thread 160 on the clamping plate 150 with the thread on the periphery of the threaded fastener 300, thereby avoiding that the locking thread 160 on the clamping plate 150 is not fully matched with the thread on the periphery of the threaded fastener 300. When the locking thread 160 and the outer thread of the threaded locking piece are fully matched, the degree of damage to the thread on the periphery of the threaded fastener 300 is small when a larger clamping force is used.

[0039] Specifically, the auxiliary clamping assembly in the present invention includes a vertical push frame 200 and a rotating push frame. The vertical push frame 200 is arranged on the workbench 100. The vertical push frame 200 is located at the periphery of the clamping frame 120. The vertical push frame 200 is connected to multiple clamping plates 150, specifically, it is connected to one end of multiple clamping plates 150 away from the threaded fastener 300. The vertical push frame 200 can reciprocate in the vertical direction, thereby driving the ends of multiple clamping plates 150 away from the threaded fastener 300 to reciprocate in the vertical direction. Since the clamping plate 150 passes through the through slot 130 on the clamping frame 120, and the side wall of the through slot 130 of the present invention is provided with a rubber protrusion 140, the rubber protrusion 140 is in contact with the two surfaces of the clamping plate 150, so the clamping plate 150 can be rotated with the through slot 130 as the center. For example, when the vertical push frame 2 When 00 moves upward in the vertical direction, it drives one end of the clamping plate 150 away from the threaded fastener 300 to move upward synchronously, while the other end of the clamping plate 150 moves downward; similarly, when the vertical push frame 200 moves downward in the vertical direction, it drives one end of the clamping plate 150 away from the threaded fastener 300 to move downward synchronously, while the other end of the clamping plate 150 moves upward. Therefore, when the vertical push frame 200 reciprocates in the vertical direction, it can drive one end of multiple clamping plates 150 close to the threaded fastener 300 to reciprocate in the vertical direction, thereby being able to move some clamping plates 150 that are not fully matched with the outer peripheral threads of the threaded fastener 300 to the position where the locking thread 160 is fully matched with the outer peripheral threads of the threaded fastener 300, thereby preventing the locking thread 160 from damaging the outer peripheral threads of the threaded fastener 300.

[0040] The rotating push frame is also arranged on the workbench 100, and the rotating push frame can push the vertical push frame 200 to rotate along the circumference of the threaded fastener 300, so that the clamping plate 150 can rotate around the outer circumference of the threaded fastener 300 under the rotation of the vertical push frame 200. When the clamping plate 150 rotates, the locking thread 160 can cooperate with the thread on the outer circumference of the threaded fastener 300 to push the threaded fastener 300 to move downward. After all the clamping plates 150 are fully matched with the threads on the outer periphery of the threaded fasteners 300, they stop moving vertically. Therefore, the clamping plates 150 can no longer move in the vertical direction. Therefore, when the vertical push frame 200 rotates, the locking threads 160 will push the threaded fasteners 300 to move downward, but the hexagonal head at the lower end of the threaded fasteners 300 is located in the stop hole 110 and cannot move downward further, so that the threaded fasteners 300 can be tightly fixed on the workbench 100, completing the clamping of the threaded fasteners 300.

[0041] In a further embodiment, in order to ensure that each clamping plate 150 can abut against the threads on the outer periphery of the threaded fastener 300 through the locking threads 160, a plurality of slide grooves 210 are provided on the vertical push frame 200. The number of the slide grooves 210 is the same as the number of the through grooves 130 on the clamping frame 120 and the positions correspond one to one. The slide grooves 210 extend along the circumference of the threaded fastener 300. A slider 211 is provided in each slide groove 210. The slider 211 can slide in the slide groove 210 along the extension direction of the slide groove 210. The slider 211 in each slide groove 210 is hinged to one end of the clamping plate 150 away from the threaded fastener 300, and the clamping plate 150 can rotate in the vertical direction at the hinged position, thereby realizing the function of the vertical push frame 200 moving back and forth in the vertical direction to drive one end of the clamping plate 150 to move back and forth in the vertical direction.

[0042] Abutment components are provided at the two ends of the slide groove 210, and the abutment components can abut against the slider 211, so that the slider 211 in each slide groove 210 can move different distances, that is, there is no restriction on the synchronous movement of all the sliders 211, because the synchronous movement of all the sliders 211 will drive all the clamping plates 150 to move synchronously. If the locking threads 160 of one or two clamping plates 150 have been tightly abutted against the threads on the outer periphery of the threaded fastener 300 before the vertical push frame 200 rotates, the vertical push frame 200 is no longer required. The frame 200 drives these clamping plates 150 to rotate along the circumference of the threaded fastener 300. It only needs to rotate the other clamping plates 150 that are not tightly abutted. Therefore, each clamping plate 150 needs to rotate according to its own situation, rather than blindly rotating synchronously, which will cause the locking thread 160 that has been tightly abutted against the outer peripheral thread of the threaded fastener 300 to damage the threaded fastener 300. Therefore, the present invention is provided with an abutment assembly that can enable each clamping plate 150 to move individually, thereby not restricting the synchronous rotation of all the clamping plates 150.

[0043] Specifically, the abutment assembly in the present invention includes an elastic member 220 and an abutment plate 230. Figure 4 and Figure 5 As shown, one end of the elastic member 220 is fixedly arranged at the end of the slide groove 210, and the other end of the elastic member 220 is fixedly connected to the abutment plate 230, and the abutment plate 230 abuts against the slider 211 located inside the slide groove 210. There are two elastic members 220 and abutment plates 230 in each slide groove 210, and the two elastic members 220 and abutment plates 230 are respectively located at the two ends of the slide groove 210 so as to abut against the two ends of the slider 211 respectively. When the vertical push frame 200 rotates, the slide groove 210 rotates synchronously with the vertical push frame 200, and the abutment plate 230 and the elastic member 220 push the slider 211, and the slider 211 drives the clamping plate 150.

[0044] If the locking thread 160 on one of the clamping plates 150 is not tightly against the thread on the periphery of the threaded fastener 300, the vertical push frame 200 will push the slider 211 through the elastic member 220 and the abutment plate 230 when it rotates, and the slider 211 will drive the clamping plate 150 to rotate. When the clamping plate 150 rotates until the locking thread 160 is tightly against the thread on the periphery of the threaded fastener 300, the elastic member 220 begins to be compressed, thereby applying a force to the slider 211 to prevent the clamping Plate 150 is loosened; if the locking thread 160 of one of the clamping plates 150 is tightly abutted against the threads on the periphery of the threaded fastener 300, the elastic member 220 will be compressed when the vertical push frame 200 rotates. At this time, the elastic member 220 and the abutting plate 230 cannot push the slider 211, thereby avoiding pushing the clamping plate 150 to rotate and damaging the threads on the periphery of the threaded fastener 300, and the elastic member 220 has elastic force that enables the clamping plate 150 to tighten the threaded fastener 300.

[0045] It should be noted that the elastic member 220 in the present invention is a spring, and of course it can also be other elastic elements, which is not specifically limited here.

[0046] In a further embodiment, in order to realize the reciprocating movement of the vertical push frame 200 in the vertical direction, and the rotating push frame drives the vertical push frame 200 to rotate, the vertical push frame 200 has a telescopic part. Specifically, a first telescopic member 241 is provided at the telescopic part. The first telescopic member 241 is distributed along the vertical direction. One end of the first telescopic member 241 is connected to the vertical push frame 200, and the other end of the first telescopic member 241 is connected to the sliding plate 240. The sliding plate 240 is slidably connected to the workbench 100. When the first telescopic member 241 reciprocates and telescopes, it can drive the vertical push frame 200 to reciprocate in the vertical direction; an annular slide rail 170 is provided on the workbench 100, and the annular slide rail 170 is located on the outer periphery of the stop hole 110. A sliding protrusion 242 is provided at the lower end of the sliding plate 240, and the sliding protrusion 242 is located on the annular In the slide rail 170, the width of the annular slide rail 170 is greater than the diameter of the sliding protrusion 242, so that the sliding protrusion 242 can slide circumferentially and radially in the annular slide rail 170, and the rotating push frame includes a vertical rod 250 and a second telescopic member 251. The vertical rod 250 is fixedly set on the workbench 100, and the second telescopic member 251 is arc-shaped to adapt to the rotation of the vertical push frame 200. The second telescopic member 251 extends along the circumference of the threaded fastener 300. One end of the second telescopic member 251 is fixedly connected to the vertical rod 250, and the other end of the second telescopic member 251 is fixedly connected with a push plate 252. The push plate 252 can abut against the side wall of the vertical push frame 200. When the second telescopic member 251 is extended or retracted, the vertical push frame 200 can be pushed to rotate along the circumference of the threaded fastener 300 through the push plate 252.

[0047] Specifically, a third telescopic member 260 is further provided on the workbench 100, one end of the third telescopic member 260 is fixedly connected to the workbench 100, and the third telescopic member 260 is distributed along the radial direction of the threaded fastener 300, such as Figure 2 As shown, the other end of the third telescopic member 260 can abut against the vertical push frame 200, and in the present embodiment, it abuts against the sliding plate 240. When the third telescopic member 260 is extended or retracted, it can drive the vertical push frame 200 to move radially along the threaded fastener 300. That is to say, when the third telescopic member 260 is extended, the third telescopic member 260 pushes the sliding plate 240 in the annular slide rail 170 to approach the threaded fastener 300, so the sliding plate 240 drives the vertical push frame 200 to move toward the direction approaching the threaded fastener 300. At this time, the clamping plate 150 connected to the vertical push frame 200 moves toward the direction approaching the threaded fastener 300 to clamp the threaded fastener 300.

[0048] In a further embodiment, an arc-shaped plate 261 is provided on one end of the third telescopic member 260 of the present invention close to the threaded fastener 300, and the end surface of the sliding plate 240 close to the arc-shaped plate 261 is also an arc-shaped surface so as to adapt to the sliding of the arc-shaped plate 261 and the sliding plate 240 in the annular slide rail 170, so that the vertical push frame 200 can be more stable when rotating along the circumference of the threaded fastener 300.

[0049] Specifically, the first telescopic members 241 in the embodiment of the present invention are arranged in pairs, and the two first telescopic members 241 are respectively located on two symmetrically arranged vertical push frames 200, and the second telescopic member 251 and the third telescopic member 260 are also arranged in pairs, specifically two pairs.

[0050] It should be noted that the first telescopic member 241, the second telescopic member 251 and the third telescopic member 260 in the embodiment of the present invention can all be telescopic cylinders, hydraulic cylinders or electronically controlled push rods, etc., and any structure that can achieve the telescopic function is not specifically limited here.

[0051] The specific working process of the auxiliary positioning and clamping device for processing a threaded fastener 300 provided by the present invention is described in combination with the above embodiments:

[0052] Limit rotation:

[0053] The hexagonal head at one end of the threaded fastener 300 to be clamped is placed into the anti-rotation hole 110 on the workbench 100. Since the anti-rotation hole 110 is hexagonal in shape, the anti-rotation hole 110 can limit the rotation of the hexagonal head.

[0054] Start clamping:

[0055] Then, the two vertical push frames 200 are installed on the workbench 100, specifically, the sliding plate 240 at the lower end of the vertical push frame 200 is slidably connected to the annular slide rail 170 on the workbench 100, and the slider 211 is installed in the slide groove 210 of the vertical push frame 200, and the clamping plate 150 hinged to the slider 211 passes through the through grooves 130 on the two symmetrically arranged clamping frames 120, so that the end of the clamping plate 150 with the locking thread 160 can be close to the threaded fastener 300. After the installation is completed, the push plate 252 on the end of the second telescopic member 251 of the rotating push frame abuts against the side wall of the vertical push frame 200, and the arc plate 261 at one end of the third telescopic member 260 abuts against the sliding plate 240 at the bottom of the vertical push frame 200.

[0056] The third telescopic member 260 is extended first, and the third telescopic member 260 drives the vertical push frame 200 to move toward the direction close to the threaded fastener 300 through the arc plate 261 and the sliding plate 240. Therefore, the multiple clamping plates 150 connected to the vertical push frame 200 can move toward the direction close to the threaded fastener 300, and the locking threads 160 on the clamping plates 150 gradually abut against the threads on the outer periphery of the threaded fastener 300. Due to the differences in the locking threads 160 on the clamping plates 150, some locking threads 160 on the clamping plates 150 may not be completely matched with the threads on the outer periphery of the threaded fastener 300. Therefore, the first telescopic member 241 reciprocates to drive the vertical push frame 200 to reciprocate in the vertical direction. Since the clamping frame 120 passes through the through slot 130 and A rubber protrusion 140 is provided on the side wall of the through groove 130, and the rubber protrusion 140 abuts against the two surfaces of the clamping plate 150. At the same time, the slider 211 on the vertical push frame 200 is hinged to the clamping plate 150, so when the vertical push frame 200 reciprocates in the vertical direction, it can drive the clamping plate 150 and the end close to the threaded fastener 300 to reciprocate in the vertical direction, and then each clamping plate 150 can be adjusted so that the locking thread 160 on each clamping plate 150 can be fully matched with the thread on the periphery of the threaded fastener 300. After the locking threads 160 on all the clamping plates 150 are fully matched with the thread on the periphery of the threaded fastener 300, the first telescopic member 241 stops telescoping, and at this time, all the clamping plates 150 are in a state of being parallel to each other.

[0057] Fully clamped:

[0058] The second telescopic member 251 begins to extend. Since the second telescopic member 251 is fixedly connected to the workbench 100 through the vertical rod 250, the second telescopic member 251 extends to push the vertical push frame 200 to rotate along the annular slide rail 170 through the push plate 252, that is, to rotate around the circumference of the threaded fastener 300. When the vertical push frame 200 rotates, the arc plate 261 on the third telescopic member 260 can still push the sliding plate 240, thereby ensuring that the vertical push frame 200 clamps the plate 150 when rotating. The threaded fastener 300 can still be clamped, and the vertical push frame 200 rotates to drive the slide groove 210 to rotate synchronously. If most of the clamping plates 150 have not locked the threaded fastener 160, and a small number of the clamping plates 150 have locked the threaded fastener 160, when the vertical push frame 200 rotates, the abutment plate 230 in the slide groove 210 pushes the slider 211 to drive most of the clamping plates 150 to rotate around the threaded fastener 300, and the second telescopic member 251 is set to extend to drive the clamping plate 150 to rotate around the threaded fastener 300. 00 rotates so that the clamping plate 150 is relatively away from the threaded fastener 300, that is, the threaded fastener 300 moves downward relative to the clamping plate 150. Since one end of the hexagonal head of the threaded fastener 300 is located in the stop hole 110, it cannot move downward. Since the first telescopic member 241 stops reciprocating telescoping, the clamping plate 150 cannot move upward either. Therefore, as the clamping plate 150 rotates, the threaded fastener 300 can be gradually fixed. When the fixation is completed, the slider 211 in the slide groove 210 begins to rotate relative to the slide groove 210, that is, the abutment plate 230 can no longer continue to push the slider 211, and those few clamping plates 150 have locked the threaded fastener 160 before the vertical push frame 200 rotates, so the slider 211 squeezes the elastic member 220. When the elastic member 220 is in a compressed state, the extension of the second telescopic member 251 is stopped to completely clamp and fix the threaded fastener 300. At this time, the threaded fastener 300 is completely fixed in the axial and circumferential directions.
