Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and in particular to a metal product processing fixture. Background Technology

[0002] Metal products are various products made from metal materials through processes such as casting, forging, and stamping. They are widely used in many fields, including construction, machinery, and electronics. In the production process of metal products, metal processing fixtures play a crucial role. These fixtures securely hold the workpiece, preventing movement or vibration during processing, ensuring machining accuracy and surface quality, and improving production efficiency.

[0003] Existing metal product processing fixtures typically clamp and fix the metal product from both sides using two clamping plates. This clamping method is not stable enough and the metal product is prone to shifting during processing, affecting the quality of the processed metal product. For example, utility model patent CN222200251U discloses a metal product processing fixture. This fixture includes a base with two symmetrically arranged mounting plates on top. A second motor is mounted on the opposite sides of each mounting plate. Rectangular boxes are fixedly connected to the opposite faces of the two mounting plates. Each rectangular box contains a transmission cavity. The output shafts of the two second motors extend into the adjacent transmission cavities. A clamping mechanism for metal product processing is provided on the base.

[0004] Although the aforementioned metal product processing fixture can drive the worm gear, worm wheel, rotating rod, and connecting rod to rotate via a second motor, thereby adjusting the angle of the two fixed plates, this device clamps and fixes the metal product only from both sides. This single point of force application easily leads to uneven stress on the metal product. For irregularly shaped metal products, this two-side clamping method makes precise positioning difficult, and the metal product is highly susceptible to displacement or overturning during processing, affecting not only processing quality but also potentially causing safety accidents.

[0005] Therefore, it is necessary to develop a metal product processing fixture to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this utility model is to provide a metal product processing fixture that can clamp and fix metal products from multiple directions, improve the fixing effect of metal products, and prevent metal products from shifting or flipping during processing.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a metal product processing fixture, including a worktable. A turntable is provided on the top surface of the worktable. A strip-shaped first sliding groove is formed in the middle of the top surface of the turntable. A first bidirectional screw is rotatably connected to the inner wall of the first sliding groove. A first slider is threaded onto both the forward and reverse threaded sections of the first bidirectional screw. An installation strip perpendicular to the first sliding groove is fixedly connected to the middle of the top surface of the turntable. A second sliding groove is formed along the length of the installation strip. A second bidirectional screw is rotatably connected to the inner wall of the second sliding groove. A second slider is threaded onto both the forward and reverse threaded sections of the second bidirectional screw. Clamping components are fixedly connected to both the first slider and the second slider.

[0009] Furthermore, the clamping assembly includes a first support column, which is vertically fixedly connected to the top surfaces of the first slider and the second slider, respectively. A horizontally arranged connecting rod is fixedly connected to the top side wall of the first support column, and a clamping plate is fixedly connected to the top of the connecting rod.

[0010] Furthermore, a plurality of second support columns are fixedly connected to the top surface of the turntable, and a support platform is fixedly connected to the top of each of the second support columns.

[0011] Furthermore, a bearing seat is fixedly installed on the worktable, and a support shaft is rotatably connected inside the bearing seat. The support shaft is fixedly connected to the turntable.

[0012] Furthermore, an internal gear ring is fixedly connected to the bottom surface of the turntable, a gear meshes on the internal gear ring, and a rotating shaft is coaxially fixedly connected to the gear. The rotating shaft passes through the worktable and is rotatably connected to it. A driving component is provided on the bottom surface of the worktable, and the driving component is used to drive the gear to rotate.

[0013] Furthermore, the driving component includes a rectangular mounting box with an open top surface and fixedly connected to the bottom surface of the workbench. A worm gear is fixedly sleeved at the bottom end of the rotating shaft. The rotating shaft is rotatably connected to the bottom surface inside the mounting box. A worm is rotatably connected between the side walls of the mounting box facing each other. The worm gear is drively connected to the worm.

[0014] Furthermore, one end of the worm gear passes through the mounting box and extends outside the mounting box, and a handwheel is fixedly connected to one end of the worm gear located in the mounting box.

[0015] Furthermore, one end of the first bidirectional screw and the second bidirectional screw respectively passes through the turntable and the mounting strip, and is fixedly connected to a rotating wheel.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] This invention utilizes a first and second sliding groove perpendicular to each other on the top surface of a turntable. A first and a second bidirectional screw drive two sliding blocks, one moving closer to the other and the other further away. This allows multiple clamping components to clamp and fix metal products from multiple directions, improving the fixation effect and preventing the metal products from shifting or flipping during processing. Furthermore, by adjusting the first and second bidirectional screws, the fixture can adapt to clamping and fixing metal products of different sizes and shapes, improving the practicality and versatility of the device.

[0018] Furthermore, by rotating the turntable connected to the worktable, and through the worm gear transmission mechanism inside the mounting box driving the gears to rotate, the inner ring drives the turntable to rotate. During processing, the operator can adjust the turntable angle by rotating the handwheel according to actual needs, achieving multi-angle processing of metal products without frequent disassembly and assembly, thus improving processing efficiency and flexibility.

[0025] The core of this utility model is to provide a metal product processing fixture that can clamp and fix metal products from multiple directions, improve the fixing effect of metal products, and prevent metal products from shifting or flipping during processing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In one specific embodiment of this utility model, such as Figures 1-3 As shown, the device includes a worktable 1, a turntable 2 on its top surface, a first groove 3 in the middle of the top surface of the turntable 2, a first bidirectional screw 4 rotatably connected to the inner wall of the first groove 3, and a first slider 5 threaded onto both the forward and reverse threaded sections of the first bidirectional screw 4. A mounting strip 6 perpendicular to the first groove 3 is fixedly connected to the middle of the top surface of the turntable 2, a second groove 7 along its length is formed on the top surface of the mounting strip 6, a second bidirectional screw 8 rotatably connected to the inner wall of the second groove 7, and a second slider 9 threaded onto both the forward and reverse threaded sections of the second bidirectional screw 8. Clamping components are fixedly connected to both the first slider 5 and the second slider 9.

[0029] The worktable 1 provides a stable support base for the entire fixture. The turntable 2 serves as the clamping platform. The first slide groove 3 cooperates with the first bidirectional screw 4. When the first bidirectional screw 4 is rotated, the two first sliders 5 can move towards or away from each other along the first slide groove 3. Similarly, the second slide groove 7 cooperates with the second bidirectional screw 8 to drive the two second sliders 9 to move. The four sets of sliders drive the clamping assembly to clamp the metal product from multiple directions. Compared to the traditional two-sided clamping method, this effectively increases the clamping points, improves clamping stability, and adapts to the positioning needs of metal products of different shapes.

[0030] In one specific embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the clamping assembly includes a first support column 10, which is vertically fixed to the top surfaces of the first slider 5 and the second slider 9. A horizontally arranged connecting rod 11 is fixedly connected to the top side wall of the first support column 10, and a clamping plate 12 is fixedly connected to the top of the connecting rod 11.

[0031] In one specific embodiment of this utility model, such as Figure 3 As shown, several second support columns 13 are fixedly connected to the top surface of the turntable 2, and a support platform 14 is fixedly connected to the top of the second support columns 13.

[0032] The second support column 13 and the support platform 14 provide bottom support for the metal product, share some of the clamping force, and further enhance the stability of the metal product during processing.

[0033] In one specific embodiment of this utility model, such as Figures 2-4 As shown, a bearing seat 15 is fixedly installed on the worktable 1, and a support shaft 16 is rotatably connected inside the bearing seat 15. The support shaft 16 is fixedly connected to the turntable 2. The cooperation between the bearing seat 15 and the support shaft 16 provides stable rotational support for the turntable 2, allowing the turntable 2 to rotate flexibly on the worktable 1.

[0034] Specifically, an internal gear ring 17 is fixedly connected to the bottom surface of the turntable 2, and a gear 18 meshes with the internal gear ring 17. A rotating shaft 19 is coaxially fixedly connected to the gear 18, and the rotating shaft 19 passes through the worktable 1 and is rotatably connected to it. A driving component is provided on the bottom surface of the worktable 1, which drives the gear 18 to rotate. During the metal product processing, if multi-angle processing of the metal product is required, the driving component drives the gear 18 to rotate. Through the meshing transmission between the gear 18 and the internal gear ring 17, the power of the driving component is transmitted to the turntable 2, realizing the rotation of the turntable 2. There is no need to disassemble and reassemble the metal product, thus improving processing efficiency.

[0035] Specifically, the driving component includes a rectangular mounting box 20 with an open top surface fixedly connected to the bottom surface of the worktable 1. A worm gear 21 is fixedly sleeved at the bottom end of a rotating shaft 19, which is rotatably connected to the inner bottom surface of the mounting box 20. A worm 22 is rotatably connected between the opposite sidewalls of the mounting box 20, and the worm gear 21 and worm 22 are connected in a transmission manner. By rotating the worm 22, the worm gear 21 and the rotating shaft 19 can be driven to rotate, thereby driving the gear 18 and the turntable 2 to rotate. The self-locking property of the worm gear 21 and worm 22 ensures that the turntable 2 will not rotate on its own due to external forces during processing, ensuring that the position of the metal product is fixed during processing and guaranteeing processing accuracy and safety.

[0036] Specifically, one end of the worm gear 22 passes through the mounting box 20 and extends outside the mounting box 20, and a handwheel 23 is fixedly connected to one end of the worm gear 22 located in the mounting box 20. The handwheel 23 is designed to facilitate manual control of the rotation of the worm gear 22 by the operator. By rotating the handwheel 23, the rotation angle of the turntable 2 can be precisely adjusted, making operation simple and convenient.

[0037] In one specific embodiment of this utility model, such as Figures 1-3As shown, one end of the first bidirectional screw 4 and the second bidirectional screw 8 passes through the turntable 2 and the mounting strip 6, respectively, and is fixedly connected to a rotating wheel 24. The rotating wheel 24 is designed to facilitate the operator to rotate the first bidirectional screw 4 and the second bidirectional screw 8. By rotating the rotating wheel 24, the positions of the first slider 5 and the second slider 9 can be quickly adjusted, thereby adjusting the spacing of the clamping plates 12 to meet the clamping requirements of metal products of different sizes.

[0038] The working principle of this utility model is as follows: When using this metal product processing fixture, firstly, according to the shape and size of the metal product, the distance between the two first sliders 5 is adjusted by rotating the wheel 24 at the end of the first bidirectional screw 4. Then, the distance between the two second sliders 9 is adjusted by rotating the wheel 24 at the end of the second bidirectional screw 8, so that the four sets of clamping plates 12 are in a suitable initial position. The metal product is placed on the support table 14, and the position of the four sets of clamping plates 12 is finely adjusted again to make the clamping plates 12 fit tightly against the surface of the metal product, clamping and fixing the metal product from multiple directions. When it is necessary to process the metal product at multiple angles, the handwheel 23 is rotated. The handwheel 23 drives the worm gear 22 to rotate. The worm gear 22, through meshing with the worm wheel 21, causes the rotating shaft 19 and the gear 18 to rotate. The gear 18 drives the internal gear ring 17 and the turntable 2 to rotate, thereby driving the metal product to rotate to the required processing angle. After processing is completed, the first bidirectional screw 4 and the second bidirectional screw 8 are rotated in the opposite direction to release the clamping plates 12, and the metal product can be removed.

[0039] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
