Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, specifically a screw processing fixture. Background Technology

[0002] Double-ended studs are a special type of fastener, also known as double-ended studs or double-ended screws. Their main feature is that both ends are threaded, with a smooth rod-like structure in the middle. This design allows double-ended studs to be used with two nuts at each end to connect two components. Due to their special structural design, double-ended studs are widely used in various industries such as machinery, valves, petrochemicals, construction, shipbuilding, and aerospace.

[0003] Due to their special shape and size, double-ended studs usually require the use of clamps during processing to ensure accuracy and efficiency. However, since the middle of double-ended studs can have different shapes, such as hexagonal or round, there is currently no clamp that can hold the middle of the double-ended stud, making it difficult to process both ends of the screw. At the same time, it is not suitable for clamping different shapes, which greatly reduces its applicability.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] The purpose of this utility model is to provide a fixing fixture for screw processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, with two partition plates connected between the inner walls of the housing. Each side of the housing and partition plates has an insertion hole. Multiple sets of rotating clamping plates are rotatably arranged on both sides of the inner walls of the housing. A first worm gear ring is rotatably arranged on each side of the inner walls of the housing corresponding to the multiple sets of rotating clamping plates. A traction frame is connected to the inner ring of the first worm gear ring. An arc-shaped inner pad is connected to one side of each rotating clamping plate. Two first drive worms are rotatably arranged between the inner walls of the housing. An external drive knob is rotatably arranged on one side of the housing. One end of each first drive worm extends outside the housing and is connected to a timing wheel at one end of the external drive knob. A timing belt is sleeved between the timing wheels. Multiple sets of rotating clamping plates are rotatably arranged on the sides of the partition plates that are close to each other. A second worm gear ring is rotatably arranged between the rotating clamping plates. A traction frame is connected to the inner ring of the second worm gear ring. A second drive worm is rotatably arranged between the inner sides of the housing. One end of the second drive worm extends through the housing and is connected to a central drive knob.

[0007] Preferably, guide holes are provided on both sides of the housing, and connecting bolts are provided on both sides of the rotating clamp. One set of connecting bolts is slidably connected to the guide holes, and the other connecting bolt is slidably connected to the traction frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: It includes a housing 1, with two partition plates 2 connected between the inner walls of the housing 1. Each side of the housing 1 and partition plates 2 has an insertion hole 3. Multiple sets of rotating clamping plates 4 are rotatably arranged on both sides of the inner walls of the housing 1. A first worm gear ring 5 is rotatably arranged on each side of the multiple sets of rotating clamping plates 4. A traction frame 6 is connected to the inner ring of the first worm gear ring 5. An arc-shaped inner pad 42 is connected to each side of the rotating clamping plates 4. Two first driving worms 7 are rotatably arranged between the inner walls of the housing 1. An external drive knob 9 is rotatably arranged on one side of the housing 1. One end of each first driving worm 7 extends into the housing. 1. A timing wheel 8 is connected to one end of the outer drive knob 9. A timing belt 10 is sleeved between the timing wheels 8. Multiple sets of rotating clamps 11 are rotatably arranged on the side of the partition plates 2 that are close to each other. As can be seen from the attached figure, the angles of the rotating clamps 11 on the side of the two partition plates 2 are different, and they are exactly hexagonal when combined. A second worm gear ring 12 is rotatably arranged between the rotating clamps 11. A traction frame 13 is connected to the inner ring of the second worm gear ring 12. A second drive worm 14 is rotatably arranged between the inner sides of the housing 1. One end of the second drive worm 14 extends out of the housing 1 and is connected to the middle drive knob 15.

[0020] Reference Figure 1 and Figure 2As shown, guide holes 43 are provided on both sides of the housing 1, and connecting bolts 41 are connected to both sides of the rotating clamping plate 4. One set of connecting bolts 41 is slidably connected to the guide holes 43, and the other set of connecting bolts 41 is slidably connected to the traction frame 6. When the first worm gear ring 5 is driven by the first drive worm 7, the rotating clamping plate 4 can be rotated through the traction frame 6. When the rotating clamping plate 4 rotates, one end of the connecting bolt 41 will slide along the traction frame 6, while the other end will rotate along the guide holes 43, thereby opening and closing each set of rotating clamping plates 4. The inner arc-shaped inner pad 42 is used to clamp the middle end of the circular double-ended screw.

[0021] Reference Figure 3 As shown, each of the two rotating clamping plates 11 is connected to an inner connecting shaft head 111 on one side that is close to each other. The inner connecting shaft head 111 is slidably connected to the traction frame 13. When the second worm ring 12 is driven by the second driving worm 14, the inner connecting shaft head 111 can be driven by the traction frame 13, thereby causing the rotating clamping plate 111 to rotate. At the same time as the rotating clamping plate 111 rotates, the inner connecting shaft head 111 will slide along the traction frame 13.

[0022] Reference Figure 3 As shown, each side of the partition plate 2 is provided with a guide hole 21, and each side of the rotating clamping plate 11 that is far apart from each other is connected with an external connecting shaft head 112. One end of the external connecting shaft head 112 is slidably connected to the guide hole 21. When the rotating clamping plate 11 rotates, the external connecting shaft head 112 will slide along the guide hole 21, thereby opening and closing the rotating clamping plate 11 and clamping the middle end of the hexagonal double-ended screw.

[0023] Reference Figure 2 and Figure 3 As shown, the second drive worm 14 meshes with the second worm ring 12, and the first drive worm 7 meshes with the first worm ring 5, so that when the second drive worm 14 or the first drive worm 7 is rotated, each set of second worm rings 12 or first worm rings 5 ​​can be driven to rotate simultaneously, achieving good synchronization.

[0024] Reference Figure 1 As shown, mounting brackets 16 are connected to both sides of the housing 1. Different mounting brackets 16 can be selected to install and fix the housing 1 as needed, so as to clamp the middle end of the double-ended screw.

[0025] The implementation principle of this application is as follows: In use, the device is installed in a suitable position using the mounting bracket 16, and then the double-ended screw is inserted into the insertion hole 3 so that the middle end of the double-ended screw is located inside the device. Then, depending on the shape of the middle end of the double-ended screw, if it is round, the external drive knob 9 is turned, which drives the two first drive worm gears 7 to rotate through the timing wheel 8, thereby driving the first worm gear ring 5, so that multiple sets of rotating clamping plates 4 are merged to clamp and fix the round middle end of the double-ended screw. If it is hexagonal, the central drive knob 15 is turned, which drives the second worm gear ring 12 to rotate through the first drive worm gear 7, so that the internal rotating clamping plates 11 are merged to clamp and fix the hexagonal middle end of the double-ended screw.
