Therefore, some people call a type of fasteners with national standards standard fasteners, or simply standard parts.

[0003] The existing fastener clamping equipment has the following problems: 1. A large amount of high-temperature debris will be generated during the clamping, grinding or filing of the fasteners, and these high-temperature debris will cause defects on the surface of the fasteners; 2. The previous fastener clamping only clamps the outside, and simply clamping the outside will cause problems such as falling off due to excessive external force during the processing. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A clamping and assembling device based on automobile fasteners, comprising an operating table, a fastener, an outer clamp and a vacuum cleaner, wherein the fastener is placed on the top of the operating table, the outer clamp is arranged on the outer side of the fastener, the outer clamp is fixedly connected to the operating table, the vacuum cleaner is fixedly installed inside the operating table, an inner clamp is arranged on the outer side of the vacuum cleaner, the inner clamp is fixedly installed inside the operating table, and the inner clamp is arranged just below the fastener;

[0007] The vacuum cleaner includes a double-layer hole, which is opened inside the operating table. The top of the double-layer hole is connected with the through hole. A piston is slidably installed on the inner side of the double-layer hole. A through pipe is fixedly connected to the bottom of the piston. A bottom pull rod is fixedly connected to the bottom of the through pipe. The outer side of the bottom pull rod is slidably connected to the operating table. The outer side of the piston is slidably connected to the inner wall of the second layer hole of the double-layer hole. Because the cross-sectional area of ​​the through hole and the first layer hole of the double-layer hole is much smaller than the cross-sectional area of ​​the second layer hole of the double-layer hole, when the piston slides downward along the second layer hole, a huge suction force is generated at its top, causing debris to be sucked into the double-layer hole.

[0008] An external tube is sleeved on the outer side of the through tube, and a collection frame is provided at one end of the external tube away from the through tube. The bottom of the collection frame is fixedly installed inside the operating table, and the outer side of the collection frame is fixedly connected to the inner clamp. A hole is opened in the central part of the piston, so the debris under suction will enter the through tube through the hole on the piston. In addition, the bottom of the through tube is blocked by the bottom pull rod, and the outer side of the through tube is connected to the external tube, so that the debris will eventually enter the collection frame through the external tube for storage.

[0009] The inner clamp device comprises a square frame, one end of the square frame is fixedly connected to the collecting frame, an end of the square frame away from the collecting frame is sleeved with an insert tube, and an inner clamp assembly is arranged inside the square frame.

[0015] Preferably, a flat claw is fixedly connected to the outer side of the second connecting rod, and a first rotating shaft is rotatably installed inside the flat claw, and both ends of the first rotating shaft are fixedly connected to the square frame. The flat claw is rotated by the first rotating shaft, so that the convex claw rotates clockwise through the second rotating shaft, and the flat claw rotates counterclockwise through the first rotating shaft, so that the relative rotation of the two plays a role in pre-compression and fixing the inner wall of the fastener.

[0016] Preferably, hole blocks are fixedly connected on both sides of the transmission assembly, a reinforcer is slidably installed inside the hole block, the reinforcer includes a hole groove, the hole groove is opened on the inner side of the hole block, and a stop block is slidably installed on the inner side of the hole groove.

[0017] Preferably, the bottom of the stop block is fixedly connected with a slider, the bottom of the slider is provided with a circular hole plate, the top of the circular hole plate is provided with a flat groove, and the inner side of the flat groove is slidably connected with the slider. The bottom of the stop block slides in the flat groove through the slider, so the stop block will slide to both sides through the flat groove, and at this time, the side of the two stop blocks away from the trapezoidal rod will squeeze the flat stop claw and the convex stop claw respectively, thereby achieving the effect of formal fixing.

[0018] Preferably, a top plate is fixedly connected to the top of the circular hole plate, elastic bars are fixedly connected to both sides of the top plate, and one end of the elastic bar away from the top plate is fixedly connected to the stop block.

[0019] Preferably, a trapezoidal rod is provided at the center of the circular hole plate, and the outer sides of the trapezoidal rod are respectively threadedly connected to the bottom of the operating table and the hole block. The diameter of the hole opened at the center of the circular hole plate is smaller than the maximum cross-sectional area of ​​the trapezoidal rod, and the outer side of the trapezoidal rod also pushes the stop block to the outermost end of the flat groove, thereby playing the role of clamping the inside of fasteners with different inner diameters.

[0020] The present invention provides a clamping assembly device based on automobile fasteners. It has the following beneficial effects:

[0021] 1. The clamping and assembling equipment based on automobile fasteners rotates the threaded rod in the forward direction, so that the clamping block threadedly connected thereto will move forward in the external plate.

[0022] Second, the clamping and assembling equipment based on automobile fasteners has a hole in the center of the piston, so that the debris under suction will enter the through-tube through the hole on the piston. In addition, the bottom of the through-tube is blocked by the bottom tie rod, and the outside of the through-tube is connected to the external tube, so that the debris will eventually enter the collection frame through the external tube for storage.

[0023] 3. The clamping and assembling equipment based on automobile fasteners is fixedly connected to the flat claw through the central section of the No. 2 fixed connecting rod. In addition, the flat claw is rotated by the No. 1 rotating shaft. Therefore, the convex claw is rotated clockwise by the No. 2 rotating shaft, and the flat claw is rotated counterclockwise by the No. 1 rotating shaft, so that the relative rotation of the two can pre-extrude and fix the inner wall of the fastener.

[0024] 4. The clamping and assembling equipment based on automobile fasteners slides the bottom of the block in the flat groove through a slider, so the block slides to both sides through the flat groove. At this time, the two sides of the block away from the trapezoidal rod will squeeze the flat claw and the convex claw respectively, thereby achieving the effect of formal fixing.

[0025] 5. The clamping and assembling equipment based on automobile fasteners continues to move upward through the trapezoidal rod. At this time, the surface of the trapezoidal rod will drive the circular hole plate to move upward together. Because the diameter of the hole opened in the center of the circular hole plate is smaller than the maximum cross-sectional area of ​​the trapezoidal rod, the outer side of the trapezoidal rod will also push the block to the outermost end of the flat groove, thereby playing a role in clamping the inside of fasteners with different inner diameters.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0036] The first embodiment, as Figure 1-Figure 4 As shown, the present invention provides a technical solution: a clamping and assembling device based on automobile fasteners, comprising an operating table 1, a fastener 2, an outer clamp 3 and a vacuum cleaner 4, wherein the fastener 2 is placed on the top of the operating table 1, the outer clamp 3 is arranged on the outside of the fastener 2, the outer clamp 3 is fixedly connected to the operating table 1, the vacuum cleaner 4 is fixedly installed inside the operating table 1, an inner clamp 5 is arranged on the outside of the vacuum cleaner 4, the inner clamp 5 is fixedly installed inside the operating table 1, and the inner clamp 5 is arranged directly below the fastener 2.

[0037] The external clamp 3 includes a leak receiving plate 31, which is placed on the outside of the fastener 2. A through hole 32 is provided at the bottom of the leak receiving plate 31. An eye-shaped shell 33 is fixedly connected to the side of the leak receiving plate 31 away from the fastener 2. A fixing rod 34 is inserted through the top of the eye-shaped shell 33. The bottom of the fixing rod 34 is fixedly connected to the operating table 1. A clamping block 35 is slidably installed inside the eye-shaped shell 33. An external plate 36 is slidably installed on the side of the clamping block 35 away from the eye-shaped shell 33. The bottom of the external plate 36 is fixedly connected to the operating table 1. A threaded rod 37 is threadedly connected to the side of the clamping block 35. The threaded rod 37 is threadedly connected to the external plate 36. By placing the fastener 2 on the operating table 1, and then covering the leak plate 31 on the outside of the fastener 2, and at the same time, the eye-shaped shell 33 connected to the leak plate 31 will also be placed on the periphery of the fastener 2, and then fixed by the fixing rod 34, when the above placement is completed, the threaded rod 37 is rotated so that the clamping block 35 threadedly connected thereto will move forward in the external plate 36, and then the clamping block 35 will gradually move toward the direction of the fastener 2, and finally the clamping block 35 will squeeze and clamp the leak plate 31, thereby indirectly realizing the clamping effect on the outside of the fastener 2, wherein the leak plate 31 not only plays a role in receiving debris, but also plays a role in fixing the fastener 2, and the clamping block 35 indirectly plays a role in increasing the clamping and fixing effect on the outside of the fastener 2.

[0038] The vacuum cleaner 4 includes a double-layer hole 41, which is opened inside the operating table 1. The top of the double-layer hole 41 is connected to the through hole 32. A piston 42 is slidably installed on the inner side of the double-layer hole 41. A through pipe 43 is fixedly connected to the bottom of the piston 42. A bottom pull rod 44 is fixedly connected to the bottom of the through pipe 43. The outer side of the bottom pull rod 44 is slidably connected to the operating table 1. An external tube 45 is sleeved on the outer side of the through pipe 43. A collection frame 46 is provided at one end of the external tube 45 away from the through pipe 43. The bottom of the collection frame 46 is fixedly installed inside the operating table 1, and the outer side of the collection frame 46 is fixedly connected to the inner clamp 5. When grinding or filing the outer surface of the fastener 2, a large amount of debris will always be generated, and these debris will fall into the leak plate 31. In addition, a through hole 32 is opened at the bottom of the leak plate 31, and the bottom of the through hole 32 is connected to the double-layer hole 41. Then, the bottom pull rod 44 is pulled downward, so that the through pipe 43 connected to the top thereof will move downward, and the top of the through pipe 43 is connected to the piston 42, and the outer side of the piston 42 is slidably connected to the inner wall of the second layer of the double-layer hole 41. Because the cross-sectional area of ​​the through hole 32 and the first layer of the double-layer hole 41 is much smaller than the cross-sectional area of ​​the second layer of the double-layer hole 41, when the piston 42 slides downward along the second layer of the hole, its top will generate a huge suction force to suck the debris into the double-layer hole 41.

[0039] The center of the piston 42 is provided with a hole, so the debris under suction will enter the through-tube 43 through the hole on the piston 42. In addition, the bottom of the through-tube 43 is blocked by the bottom pull rod 44. At the same time, the outer side of the through-tube 43 is connected to the external tube 45, so that the debris will eventually enter the collection frame 46 through the external tube 45 for storage.

[0040] The second embodiment, as Figure 5-Figure 8 As shown, the inner clamp 5 includes a square frame 51 , one end of which is fixedly connected to the collecting frame 46 , an end of the square frame 51 away from the collecting frame 46 is sleeved with an insert 52 , and an inner clamp assembly 53 is arranged inside the square frame 51 .

[0041] The inner clamping assembly 53 includes a slide groove 531, which is opened on the inner side of the square frame 51. A moving block 532 is slidably installed inside the slide groove 531. A spring 533 is fixedly connected to the outer side of the moving block 532. One end of the spring 533 away from the moving block 532 is fixedly connected to the square frame 51. A bottom connecting bar 534 is fixedly connected to the bottom of the moving block 532. A No. 1 fixed connecting rod 535 is fixedly connected to the surface of the bottom connecting bar 534. A convex claw 5305 is fixedly connected to the center section of the outer side of the No. 1 fixed connecting rod 535. A No. 2 rotating shaft 5306 is rotatably connected to the inner side of the convex claw 5305. Both ends of the No. 2 rotating shaft 5306 are fixedly connected to the square frame 51. A No. 1 ring sleeve 536 is fixedly connected to the outer side of the No. 1 fixed connecting rod 535. The bottom connecting bar 534 is arranged between the No. 1 ring sleeve 536 and the convex claw 5305. A No. 1 retractor 537 is fixedly connected to the outer side of the No. 1 ring sleeve 536, a transmission assembly 538 is installed on the end of the No. 1 retractor 537 away from the No. 1 ring sleeve 536, a No. 2 retractor 539 is installed on the side of the transmission assembly 538 away from the No. 1 retractor 537, a No. 2 ring sleeve 5301 is fixedly connected to the end of the No. 2 retractor 539 away from the transmission assembly 538, a No. 2 fixed connecting rod 530 is fixedly connected to the inner side of the No. 2 ring sleeve 5301, a flat abutment claw 5302 is fixedly connected to the outer side of the No. 2 fixed connecting rod 530, a No. 1 rotating shaft 5303 is rotatably installed inside the flat abutment claw 5302, both ends of the No. 1 rotating shaft 5303 are fixedly connected to the square frame 51, both sides of the transmission assembly 538 are fixedly connected to hole blocks 5304, and a reinforcer 5307 is slidably installed inside the hole block 5304.

[0042] By pushing the insert tube 52 to the left, the insert tube 52 is pressed against the moving block 532, and the moving block 532 moves to the left along the slide groove 531, wherein the moving block 532 is fixedly connected with a spring 533 on the same side of the insert tube 52, and the other end of the spring 533 is connected to the square frame 51, and the spring 533 is always in a compressed state, which plays a role in resetting the moving block 532.

[0043] When the shift block 532 moves to the left, the bottom connecting bar 534 fixed at the bottom thereof moves to the left and drives the No. 1 fixed connecting rod 535 connected thereto to move, wherein the center section of the No. 1 fixed connecting rod 535 is fixedly connected to the convex claw 5305, and the convex claw 5305 is rotated by the No. 2 rotating shaft 5306, so when the shift block 532 moves to the left, the convex claw 5305 rotates clockwise;

[0044] When the No. 1 fixed link 535 moves to the left, the No. 1 ring sleeve 536 fixed on its surface will move to the left accordingly, and the No. 1 retractor 537 fixed on the surface of the No. 1 ring sleeve 536 will shrink. In addition, the other end of the No. 1 retractor 537 is connected to the No. 2 retractor 539 through a transmission assembly 538. The function of the transmission assembly 538 is that when the No. 1 retractor 537 shrinks, the No. 2 retractor 539 will shrink accordingly. The other end of the No. 2 retractor 539 is connected to the No. 2 ring sleeve 530. 1, and the inner side of the No. 2 ring sleeve 5301 is connected to the No. 2 fixing rod 530, and the central section of the No. 2 fixing rod 530 is fixedly connected to the flat claw 5302, and the flat claw 5302 is rotated by the No. 1 rotating shaft 5303. Therefore, the convex claw 5305 is finally rotated clockwise by the No. 2 rotating shaft 5306, and the flat claw 5302 is rotated counterclockwise by the No. 1 rotating shaft 5303, so that the relative rotation of the two can play a role in pre-extrusion and fixation of the inner wall of the fastener 2.

[0045] The reinforcer 5307 includes a hole groove 3071, which is provided on the inner side of the hole block 5304. A stop block 3072 is slidably installed on the inner side of the hole groove 3071. A slider 3078 is fixedly connected to the bottom of the stop block 3072. A circular hole plate 3074 is provided at the bottom of the slider 3078. A flat groove 3077 is provided on the top of the circular hole plate 3074. The inner side of the flat groove 3077 is slidably connected to the slider 3078. A top plate 3073 is fixedly connected to the top of the circular hole plate 3074. Both sides of the top plate 3073 are fixedly connected with elastic bars 3076. One end of the elastic bar 3076 away from the top plate 3073 is fixedly connected to the stop block 3072. A trapezoidal rod 3075 is provided at the center of the circular hole plate 3074. The outer sides of the trapezoidal rod 3075 are respectively threadedly connected to the bottom of the operating table 1 and the hole block 5304.

[0046] Then, the trapezoidal rod 3075 threadedly connected to the operating table 1 and the hole block 5304 is rotated in the forward direction, so that the trapezoidal rod 3075 moves upward, and the outer periphery of the top of the trapezoidal rod 3075 will first squeeze the stop block 3072, and the bottom of the stop block 3072 slides in the flat groove 3077 through the slider 3078, so the stop block 3072 will slide to both sides through the flat groove 3077. At this time, the two stops 3072 away from the side of the trapezoidal rod 3075 will squeeze the flat stop claw 5302 and the convex stop claw 5305 respectively, thereby achieving the formal fixing effect.

[0047] As the trapezoidal rod 3075 continues to move upward, the surface of the trapezoidal rod 3075 will drive the circular hole plate 3074 to move upward together, because the diameter of the hole opened in the center of the circular hole plate 3074 is smaller than the maximum cross-sectional area of ​​the trapezoidal rod 3075. At the same time, the outer side of the trapezoidal rod 3075 will also push the stop block 3072 to the outermost end of the flat groove 3077, thereby playing the role of clamping the interior of fasteners 2 with different inner diameters.
