Description

Technical Field

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

[0002] Screw machining is a precise and crucial manufacturing process. The first step is material selection: based on the screw's application and performance requirements, a suitable metal material, such as medium carbon steel or alloy steel, is chosen. Next, rough machining is performed, using turning to initially shape the screw and determine its basic shape and dimensions, leaving allowance for subsequent machining.

[0003] During the machining process, the screw is turned by a machine tool. However, if the workpiece is only clamped at one end by the chuck of the machine tool for turning, while the other end is suspended in the air, the rotating workpiece will be unstable, resulting in deviations in the straightness of the rough-machined workpiece. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a screw clamping device suitable for screw processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw clamping device suitable for screw processing, comprising a support frame, a rotating mechanism mounted on the top of the support frame, and a fixing mechanism mounted on the left side of the rotating mechanism;

[0006] The rotating mechanism includes a circular track, which is fixedly connected to the top of the support frame. A movable block is provided at the bottom of the circular track. First support rods are fixedly connected to the top two sides of the movable block. A first rotating wheel is rotatably connected to the top of the first support rod. The outer wall of the first rotating wheel is in rolling connection with the inner wall of the inner ring of the circular track. A second support rod is fixedly connected to the bottom of the movable block. A second rotating wheel is rotatably connected to the bottom of the second support rod. The outer wall of the second rotating wheel is in rolling connection with the inner walls of the inner and outer rings of the circular track.

[0007] Preferably, the circular track has an operating hole in the middle, and a placement ring groove is integrally formed on the left side of the circular track. The rotation shafts of the first and second rotating wheels extend to the placement ring groove on the other side.

[0008] Preferably, both the inner and outer rings on the left side of the circular track are fixedly connected to limit rings, which prevent the second rotating wheel and the first rotating wheel from disengaging from the circular track.

[0009] Preferably, the fixing mechanism includes a mounting plate. The mounting plate is fixedly connected to the left side of the movable block. A fixing block is fixedly connected to the bottom left side of the mounting plate. A threaded rod is threadedly connected to the middle of the fixing block. A movable seat is rotatably connected to the top of the threaded rod. A first movable rod and a second movable rod are hinged to the front and rear positions of the top left side of the movable seat, respectively. A rotating pin is rotatably connected to the top of both the first and second movable rods. A second clamping rod and a first clamping rod are fixedly connected to the first and second movable rods, respectively, through the rotating pins. The bottoms of the second clamping rod and the first clamping rod are hinged to the top left side of the mounting plate.

[0010] Preferably, a groove is provided in the middle of the left side of the mounting plate, and the movable seat is slidably connected in the groove.

[0011] Preferably, a turning hole is provided in the middle of the bottom of the threaded rod, and a rotating rod is inserted into the turning hole.

[0012] Compared with the prior art, this utility model provides a screw clamping device suitable for screw machining, which has the following beneficial effects:

[0013] 1. This screw clamping device, applicable to screw machining, effectively solves the problem of unstable rotation caused by one end of the screw being suspended during machining through its designed rotating mechanism. During screw machining, when the machine tool drives the screw to rotate, the movable block can rotate flexibly within the circular track with the aid of the first and second rotating wheels. Since the two rotating wheels roll in contact with the inner and outer rings of the circular track respectively, they provide stable support and guidance for the movable block, ensuring its smooth rotation. This also allows the fixed mechanism connected to the movable block and the clamped screw to rotate stably, avoiding wobbling caused by one end of the screw being suspended, thus ensuring the straightness of the rough-machined workpiece and improving the precision of screw machining.

[0014] 2. This screw clamping device, suitable for screw machining, uses a fixed mechanism to ensure stable clamping of the screw during machining, further solving the problem of machining instability. Inserting the rotating rod into the actuating hole at the bottom of the threaded rod and rotating it causes the movable seat to move up and down within the groove. When the movable seat moves upward, it pushes the first and second movable rods to rotate around the hinge point with the mounting plate, thereby causing the first and second clamping rods to move closer together, clamping the screw; conversely, it releases the screw. This method of opening and closing the clamping rods via threaded rod transmission allows for flexible adjustment according to the screw's size, providing a stable and reliable clamping force. During screw machining, stable clamping ensures that the screw will not shift or wobble during turning and other machining operations. Working in conjunction with the rotating mechanism, it effectively guarantees the precision of screw machining and improves product quality. Attached Figure Description

[0021] 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.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Please see Figure 1-3 A screw clamping device suitable for screw processing includes a support frame 1, a rotating mechanism 3 mounted on the top of the support frame 1, and a fixing mechanism 4 mounted on the left side of the rotating mechanism 3;

[0026] The rotating mechanism 3 includes a circular track 31, which is fixedly connected to the top of the support frame 1. A movable block 32 is provided at the bottom of the circular track 31. A first support rod 33 is fixedly connected to both sides of the top of the movable block 32. A first rotating wheel 36 is rotatably connected to the top of the first support rod 33. The outer wall of the first rotating wheel 36 is in rolling connection with the inner wall of the inner ring of the circular track 31. A second support rod 34 is fixedly connected to the bottom of the movable block 32. A second rotating wheel 35 is rotatably connected to the bottom of the second support rod 34. The outer wall of the second rotating wheel 35 is in rolling connection with the inner wall of the inner and outer rings of the circular track 31.

[0027] The rotating mechanism 3 effectively solves the problem of unstable rotation caused by one end being suspended during screw machining. During screw machining, when the machine tool drives the screw to rotate, the movable block 32 can rotate flexibly within the annular track 31 with the aid of the first rotating wheel 36 and the second rotating wheel 35. Since the two rotating wheels roll in contact with the inner and outer rings of the annular track 31 respectively, they provide stable support and guidance for the movable block 32, ensuring its smooth rotation. This also allows the fixing mechanism 4 connected to the movable block 32 and the clamped screw to rotate stably, avoiding wobbling caused by one end of the screw being suspended, thus ensuring the straightness of the rough-machined workpiece and improving the precision of screw machining.

[0028] An operating hole is provided in the middle of the circular track 31, and a placement ring groove is integrally formed on the left side of the circular track 31. The rotation shafts of the first rotating wheel 36 and the second rotating wheel 35 extend to the placement ring groove on the other side.

[0029] Limiting rings 37 are fixedly connected to the inner and outer rings on the left side of the circular track 31. The limiting rings 37 restrict the second rotating wheel 35 and the first rotating wheel 36 from disengaging from the circular track 31.

[0030] Example 2

[0031] Please see Figure 1-4Furthermore, based on Embodiment 1, the fixing mechanism 4 includes a mounting plate 49. The mounting plate 49 is fixedly connected to the left side of the movable block 32. A fixing block 48 is fixedly connected to the bottom left side of the mounting plate 49. A threaded rod 46 is threadedly connected to the middle of the fixing block 48. A movable seat 45 is rotatably connected to the top of the threaded rod 46. A first movable rod 43 and a second movable rod 44 are respectively hinged at the front and rear positions of the top left side of the movable seat 45. A rotating pin 431 is rotatably connected to the top of both the first movable rod 43 and the second movable rod 44. A second clamping rod 42 and a first clamping rod 41 are fixedly connected to the first movable rod 43 and the second movable rod 44 respectively through the rotating pin 431. The bottoms of the second clamping rod 42 and the first clamping rod 41 are respectively hinged to the top left side of the mounting plate 49.

[0032] The design of the fixing mechanism 4 ensures stable clamping of the screw during processing, further resolving the issue of processing instability. Inserting the rotating rod 2 into the actuating hole 47 at the bottom of the threaded rod 46 and rotating it causes the movable seat 45 to move up and down within the slide groove 481. When the movable seat 45 moves upward, it pushes the first movable rod 43 and the second movable rod 44 to rotate around the hinge point with the mounting plate 49, thereby causing the first clamping rod 41 and the second clamping rod 42 to move closer together, clamping the screw; conversely, it releases the screw. This method of opening and closing the clamping rods via the threaded rod 46 allows for flexible adjustment according to the screw's dimensions, providing a stable and reliable clamping force. During screw processing, stable clamping ensures that the screw will not shift or wobble during turning and other machining operations. Working in conjunction with the rotating mechanism 3, it effectively guarantees the precision of screw processing and improves product quality.

[0033] A groove 481 is provided in the middle of the left side of the mounting plate 49, and the movable seat 45 is slidably connected in the groove 481.

[0034] A turning hole 47 is provided in the middle of the bottom of the threaded rod 46, and a rotating rod 2 is inserted into the turning hole 47.

[0035] In actual operation, when this device is used, during screw machining, as the machine tool drives the screw to rotate, the movable block 32 can rotate flexibly within the annular track 31 with the aid of the first rotating wheel 36 and the second rotating wheel 35. Since the two rotating wheels roll in contact with the inner and outer rings of the annular track 31 respectively, they provide stable support and guidance for the movable block 32, ensuring its smooth rotation. This also allows the fixed mechanism 4 connected to the movable block 32 and the clamped screw to rotate stably, avoiding wobbling caused by one end of the screw being suspended in the air, thus ensuring the straightness of the rough-machined workpiece and improving the precision of screw machining.

[0036] Insert the rotating rod 2 into the actuating hole 47 at the bottom of the threaded rod 46 and rotate it. The rotation of the threaded rod 46 causes the movable seat 45 to move up and down within the slide groove 481. When the movable seat 45 moves upward, it pushes the first movable rod 43 and the second movable rod 44 to rotate around the hinge point with the mounting plate 49, thereby causing the first clamping rod 41 and the second clamping rod 42 to move closer together, thus clamping the screw; conversely, it releases. This method of opening and closing the clamping rods through the threaded rod 46 can be flexibly adjusted according to the size of the screw, providing a stable and reliable clamping force. During the screw machining process, stable clamping ensures that the screw will not shift or wobble during machining operations such as turning. Working in conjunction with the rotating mechanism 3, it effectively ensures the accuracy of screw machining and improves product quality.
