Description

Technical Field

[0001] The invention relates to the field of screw rod production, and more specifically to a screw rod polishing device. Background Art

[0002] Screw rod is a common mechanical component, widely used in various mechanical equipment such as automation equipment, machine tools, lifting platforms, scaffolding, etc. The production process of screw rod usually includes the following seven main steps, which can be divided into material selection, cutting and forming, wire processing, heat treatment, polishing, surface treatment and quality inspection.

[0003] The purpose of polishing in the screw production process is to remove burrs, oxide layers and other uneven parts on the surface, improve the surface smoothness and aesthetics of the screw, and also enhance the corrosion resistance of the screw, making it easier to apply anti-corrosion coatings to the screw during subsequent surface treatment. During the polishing operation of the existing screw rod, a disc-shaped clamp is used to fix the screw rod, and then a polishing wheel is used to polish the rotating screw rod. Since the factory mass-produces screw rods of the same size, the clamps corresponding to the screw rods of the same size are also of the same size. When the screw rod size required by the production order is different from the screw rod size currently produced, the production line needs to be stopped and clamps of different clamping sizes need to be replaced to clamp the screw rod. However, it takes a long time to disassemble the clamp, so the production line shutdown time is also affected to a certain extent, resulting in a decrease in production efficiency during screw rod polishing. Therefore, a clamp for screw rod polishing that can adjust its own clamping size according to the screw rod size is needed, and there is no need to replace the clamp of the corresponding size according to the screw rod size, so as to improve production efficiency.

The connecting tube 62 passes through the disc clamp 4 and is connected with the piston chamber 44. A thrust spring 63 is arranged in the piston chamber 44, one end of the thrust spring 63 is fixedly connected to the inner wall of the piston chamber 44, and the other end of the thrust spring 63 is fixedly connected to the piston column 64. The piston column 64 is slidingly sealed in the piston chamber 44, and a plurality of groups of contraction grooves 45 are equidistantly arranged on the inner circumference of the insertion hole 47. Each group of contraction grooves 45 corresponds to and is connected with each group of piston chambers 44 one by one, and a clamping plate 65 is slidingly sealed in the contraction groove 45.

[0026] The inner wall of each set of clamping plates 65 is designed with rounded corners, and an elastic cord 66 is fixedly connected to each set of clamping plates 65 . Each set of elastic cords 66 has the same length, and multiple sets of elastic cords 66 are fixedly connected to each other. The connection points of the multiple sets of elastic cords 66 are all located at the center of the socket 47 .

[0027] When the screw rod body 14 is polished, the screw rod body 14 is first inserted into the socket 47 of the disc clamp 4 through the second vertical box 12. At this time, the disc clamp 4 will control the clamping head 43 to clamp and fix the screw rod body 14 through the adjustment component 6, and start the limit component 5 to make the disc clamp 4 rotate relative to the first vertical box 11. Then, the drive motor 31 is started to rotate forward to drive the one-way screw rod 32 and the gear 56 to rotate. The gear 56 drives the disc clamp 4 to rotate through the ring 54, so that the screw rod body 14 rotates with the disc clamp 4. At the same time, during the rotation of the one-way screw rod 32, it will drive the two sets of polishing mechanisms 2 along the direction of the slide rail 13 through the slide box 34. Figure 2 As shown in the figure, the sliding box 34 moves to the right end of the slide rail 13, and the driving motor 31 reverses and moves the sliding box 34 on the one-way screw 32 to move the two sets of polishing mechanisms 2 to the left, and the two sets of polishing mechanisms 2 will polish the screw body 14, thereby realizing the polishing of the screw body 14; The adjusting component 6 works. First, the screw body 14 to be polished is inserted into the insertion hole 47 by pushing the counterweight push block 15. If the size of the screw body 14 is smaller than the space between the multiple groups of clamping plates 65, the screw body 14 is pushed into the insertion hole 47 by pushing the counterweight push block 15. The screw body 14 will contact the interface of the multiple groups of elastic ropes 66 and stretch the elastic ropes 66. With the stretching effect of the elastic ropes 66, the multiple groups of clamping plates 65 will gradually contact the screw body 14 and increase the pressure on the surface of the screw body 14. At the same time, the multiple groups of piston rods 64 will gradually extend out of the piston cavity 44 and suck the gas in the first air bag 61 into the piston cavity 44 through the connecting pipe 62. At this time, the first air bag 61 will shrink, thereby making the multiple groups of first slide plates 42 approach each other, and making the multiple groups of clamping heads 43 approach each other, so as to achieve the effect of clamping the screw body 14, so that the disc clamp 4 can be suitable for the screw body 14 with a diameter smaller than the aperture of the insertion hole 47; When the size of the screw body 14 is larger than the space between the multiple groups of clamping plates 65, as the counterweight push block 15 pushes the screw body 14 to move into the insertion hole 47, due to the rounded corner design on the multiple groups of clamping plates 65, the screw body 14 will separate the multiple groups of clamping plates 65 from each other. At this time, the thrust spring 63 contracts, and the multiple groups of clamping plates 65 will enter the piston chamber 44. At this time, the gas in the piston chamber 44 will be pushed into the first air bag 61 through the connecting pipe 62, thereby reducing the pressure from the multiple groups of clamping heads 43 on the screw body 14, reducing the damage to the surface of the screw body 14 caused by the excessive pressure of the clamping heads 43 on the surface of the screw body 14, and at the same time, the screw body 14 can be firmly fixed by the clamping heads 43; By adjusting the component 6, the clamping effect of the clamping head 43 can be adapted to screw bodies 14 of different sizes. When clamping screw bodies 14 of different sizes, there is no need to disassemble and replace the clamps as in the prior art. Compared with the prior art, the clamping method of the clamp is optimized, the time for replacing the clamp is saved, and the production efficiency of the screw body 14 is improved. At the same time, multiple groups of clamping plates 65 and thrust springs 63 cooperate with multiple groups of clamping heads 43, which can reduce the situation in which the screw body 14 rotates due to insufficient clamping force of the multiple groups of clamping heads 43 during polishing. It should be noted here that the space between the multiple groups of clamping plates 65 and the multiple groups of clamping heads 43 under standard commonly used sizes is smaller than the inner diameter of the socket 47. The polishing wheels on the two groups of polishing mechanisms 2 can be close to or away from each other on the telescopic rod on the polishing mechanism 2, and the polishing wheels can also rotate under the action of the motor inside the polishing mechanism 2 to achieve the polishing action. This is an existing mature technology, so it will not be repeated. There is a hole in the counterweight push block 15 for the screw body 14 to be inserted. When using the counterweight push block 15, you only need to push the counterweight push block 15, and the screw body 14 will be pushed into the disc clamp 4 by the counterweight push block 15. Due to the action of the counterweight push block 15, the elastic force of the elastic rope 66 is much smaller than the gravity of the counterweight push block 15, so the elastic rope 66 will not push the clamped screw body 14 out of the socket 47. The existing clamping head 43 is inclined at the end that contacts the screw body 14. In order to facilitate the insertion of the screw body 14, the polishing mechanism 2 is symmetrically arranged with two groups.

[0028] like Figures 5 to 7As shown, an adaption component 7 is provided in each group of slide grooves 41, a plurality of groups of circular cavities 46 are equidistantly provided on the inner circumference of the disc clamp 4, an electric telescopic rod 76 is fixedly installed in each group of circular cavities 46, the adaption component 7 comprises a second slide plate 71 provided in the slide groove 41, a buffer spring 74 is fixedly connected to the second slide plate 71, a buffer spring 74 is provided between the second slide plate 71 and the first slide plate 42, a limit plate 73 is provided at the outer end of the second slide plate 71, a second air bag 72 is provided between the limit plate 73 and the second slide plate 71, the limit plate 73 and the second slide plate 71 are fixedly connected via the second air bag 72, the telescopic end of the electric telescopic rod 76 is fixedly connected to the second air pipe 75, and the second air pipe 75 is a corrugated tube.

[0029] In order to reduce the situation that the surface of the screw body 14 is damaged due to excessive clamping pressure of the clamping head 43 on the surface of the screw body 14, the length of the electric telescopic rod 76 can be controlled by inputting a numerical value through an external control panel according to the material of the screw body 14, so as to push gas into or suck gas out of the second airbag 72; When polishing begins, the inner wall of the collar 54 contacts the outer surface of the limit plate 73 under the action of the rotating gear 56, and the contact area between the two is gradually increased. At this time, the collar 54 fixes the limit plate 73, and then inputs the telescopic length of the electric telescopic rod 76 according to the material of the screw body 14. When the screw body 14 needs to be made of a harder material and a larger clamping force can be used, the electric telescopic rod 76 extends, the bellows contracts, and the gas in the bellows enters the second airbag 72, and the second airbag 72 expands. At this time, the longer the length of the buffer spring 74 contracts, the greater the pressure of the buffer spring 74 on the first slide plate 42 will be, and therefore the force of the clamping head 43 clamping the screw body 14 will be greater; When the material of the screw body 14 is relatively soft and a smaller clamping force is required, the electric telescopic rod 76 contracts and the bellows extends. The bellows will suck the gas in the second airbag 72, and the second airbag 72 will contract. At this time, the buffer spring 74 will extend. At this time, the force generated by the buffer spring 74 on the clamping head 43 is a pulling force, thereby reducing the force of the clamping head 43 clamping the screw body 14. The clamping force of multiple groups of clamping heads 43 on the surface of the screw body 14 can be adjusted according to the material of the screw body 14, thereby further reducing the situation where the surface of the screw body 14 is damaged due to excessive clamping force. At the same time, when the screw body 14 is inserted into the insertion hole 47 of the disc clamp 4, if the diameter of the screw body 14 is larger than the space between the multiple groups of clamping heads 43, the buffer spring 74 will shrink at this time to facilitate the insertion of the screw body 14; It should be noted here that: according to the spring force formula: F=k*x, it can be known that when the spring precision coefficient K constant remains unchanged, the greater the change X in its own length, the greater the force F generated. In the initial state, the ring 54 is located at the edge of the limit plate 73. When the ring 54 rotates under the action of the gear 56, the threads on the surface of the disc clamp 4 will gradually contact the surface of the limit plate 73. The extension and retraction of the electric telescopic rod 76 must be performed after the drive motor 31 is working. In order to prevent the limit plate 73 from extending from the slide groove 41, resulting in wear of the inner wall threads of the ring 54 and the limit plate 73, long-term use will accelerate the thread slippage of the ring 54. The operation of the drive motor 31, the electric telescopic rod 76 and the air pump 51 can be controlled by an external control panel.

[0030] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the surface of the limiting plate 73 is provided with threads, and the collar 54 enables the limiting plate 73 and the disc clamp 4 to be located on the same arc surface.

[0031] A positioning cavity 55 is provided on one side of the disc clamp 4 close to the first vertical box 11. The limiting assembly 5 includes an expansion ring 53 arranged on the outer surface of the first vertical box 11. The expansion ring 53 is rotatably arranged in the positioning cavity 55. A first air pipe 52 is fixedly inserted into one end of the expansion ring 53 close to the first vertical box 11. An air pump 51 is provided at the end of the first air pipe 52. The air pump 51 inflates the expansion ring 53 through the first air pipe 52. The air pump 51 is fixedly installed on the outer surface of the first vertical box 11.

[0032] Due to the threads on the surface of the limit plate 73, the driving motor 31 rotates forward, and the gear 56 on the one-way screw rod 32 drives the ring 54 to rotate, and the ring 54 will rotate as shown in FIG. Figure 5 As shown in the figure, it moves toward the left end of the disc clamp 4 and fixes the limit plate 73 to reduce the centrifugal force of the second slide plate 71, the second air bag 72 and the limit plate 73 when the driving motor 31 rotates. The three slide plates 71, the second air bag 72 and the limit plate 73 move slightly toward the outer end of the disc clamp 4 through the spring due to the excessive speed, resulting in the multiple groups of clamping heads 43 The clamping force of the screw body 14 is insufficient, the screw body 14 will not rotate, and the polishing mechanism 2 cannot completely polish the surface of the screw body 14. The driving motor 31 rotates forward. When the inner wall of the collar 54 needs to contact the surface of the limit plate 73, it is only necessary to start the air pump 51 to inject gas into the expansion ring 53 through the first air pipe 52. The expansion ring 53 will be tightly attached to the inner wall of the positioning cavity 55 to fix the disc clamp 4, so that the inner wall of the collar 54 gradually contacts the surface of the limit plate 73 and fixes the limit plate 73. The driving motor 31 is reversed. When the inner wall of the collar 54 needs to be away from the surface of the limit plate 73, the air pump 51 is started to inject gas into the expansion ring 53 through the first air pipe 52. The expansion ring 53 will be tightly attached to the inner wall of the positioning cavity 55 to fix the disc clamp 4, so that the inner wall of the collar 54 gradually moves away from the surface of the limit plate 73, and the limit plate 73 is not fixed, which facilitates the extraction of the screw rod body 14 from the socket 47. When the screw body 14 needs to be polished, since the inner wall of the collar 54 has already contacted the surface of the limit plate 73, the air pump 51 can be started to suck gas from the expansion ring 53 through the first air pipe 52, and the expansion ring 53 will shrink, and the relatively rotating disc fixture 4 will rotate in the positioning cavity 55; It should be particularly noted that the expansion ring 53 can be made of soft rubber with a hollow interior, and the material of the expansion ring 53 includes but is not limited to the soft rubber material mentioned above.

[0033] like Figure 1 , Figure 2 and Fig. 9 As shown, water pipes 341 are fixedly inserted at both ends of the slide box 34, the interior of the slide box 34 is hollow and filled with water, and the water pipes 341 pump water into the slide box 34 through the action of an external water pump, and a plurality of groups of high-pressure nozzles 342 are fixedly arranged at the bottom of the slide box 34, the drive motor 31 is a forward and reverse motor, and the drive motor 31, the electric telescopic rod 76 and the air pump 51 are electrically connected.

[0034] The driving motor 31 rotates the one-way screw 32, and then the slide box 34 moves back and forth along the direction of the one-way screw 32. Through the action of the external water pump, water is always supplied to the inside of the slide box 34 through the water pipe 341. The water in the slide box 34 is sprayed out through the high-pressure nozzle 342 to spray the screw body 14 being polished below, so as to remove impurities under the polishing of the surface of the screw body 14 and reduce the wear of the impurities on the surface of the screw body 14 during polishing. Moreover, since the slide box 34 and the polishing mechanism 2 move together, the water spraying position of the high-pressure nozzle 342 is the same as the polishing position of the polishing mechanism 2, and the screw body 14 is not directly sprayed as a whole, which saves water resources and production costs. It should be particularly noted that the water pipe 341 can be a long hose to facilitate the movement of the sliding box 34.

[0035] Usage: When polishing the screw body 14, first insert the screw body 14 through the second vertical box 12 into the socket 47 of the disc clamp 4. At this time, the disc clamp 4 will clamp and fix the screw body 14 through the clamping head 43, start the limit assembly 5 to make the disc clamp 4 rotate relative to the first vertical box 11, and then start the drive motor 31 to rotate forward to drive the one-way screw 32 and the gear 56. The gear 56 drives the disc clamp 4 to rotate through the ring 54, so that the screw body 14 rotates with the disc clamp 4. At the same time, the one-way screw 32 rotates, and it will drive the two sets of polishing mechanisms 2 along the direction of the slide rail 13 through the slide box 34. Figure 2 As shown in the figure, it moves to the right. When the slide box 34 moves to the rightmost end, the drive motor 31 reverses and moves the two sets of polishing mechanisms 2 to the left through the slide box 34 on the one-way screw rod 32.
