Description

Technical Field

[0001] The utility model belongs to the technical field of metal accessories, and particularly relates to a metal accessory positioning fixture. Background Art

[0002] In today's highly developed manufacturing industry, the processing and manufacturing of metal accessories plays a vital role. With the continuous advancement of technology and the increasing market requirements for product quality and precision, higher standards are being set for the positioning and clamping technology of metal accessories during processing.

[0003] Traditional metal component fixtures have gradually exposed numerous significant shortcomings in practical applications. First, many fixtures have outdated design concepts, simple structures, and a lack of innovation. They are often designed for specific, relatively single metal component shapes and sizes, limiting their applicability. When faced with diverse production demands requiring the handling of metal components of varying specifications, shapes, and sizes, these fixtures become inadequate and inflexible, hindering production processes and reducing efficiency.

[0004] Secondly, traditional clamps also perform poorly in terms of clamping function. The clamping force of some clamps is either too strong or too weak, making it difficult to achieve precise and stable control. Excessive clamping force can easily cause irreversible damage to metal parts, such as deformation, indentation, and even damage to their internal structure, seriously affecting product quality and performance. Insufficient clamping force can cause metal parts to loosen or shift during processing, significantly compromising machining accuracy, resulting in dimensional deviations, irregular shapes, and other problems, leading to increased scrap rates and increased production costs.

[0005] To this end, we proposed a metal accessories positioning fixture, which can not only achieve more precise positioning and clamping, reduce processing errors caused by improper clamping, but also adapt to metal accessories of different sizes and shapes. Utility Model Content

[0006] The purpose of this utility model is to provide a metal accessories positioning fixture, which can not only achieve more accurate positioning and clamping, reduce the processing error caused by improper clamping, but also can adapt to metal accessories of different sizes and shapes.

[0007] The technical solutions adopted in this application are as follows:

[0008] A metal fitting positioning fixture comprises a base, a carrying plate for carrying the metal fitting is provided at the center position of the top of the base, and a hollow cavity is opened inside the base, a telescopic assembly is provided on the inner wall of the bottom of the hollow cavity, a first connecting plate is provided on the top of the telescopic assembly, first meshing teeth are provided on both sides of the first connecting plate, a rotating shaft is rotatably provided on the front and rear side walls of the hollow cavity, a gear meshing with the first meshing teeth is fixedly sleeved on the rotating shaft, a moving assembly is provided on the left and right side walls of the hollow cavity, a second connecting plate is provided on the moving assembly, and a second meshing tooth meshing with the gear is provided on one side of the second connecting plate;

[0009] Two through holes and two movable components are provided on the top of the base, a third connecting plate is movably provided inside each through hole, the bottom of the third connecting plate is connected to the second connecting plate, a first wedge block is provided on one side of the third connecting plate, each movable component is provided with a wedge-shaped fixed block matching the first wedge block, a plurality of elastic components are provided on one side of the wedge-shaped fixed block, and a fixed disk is provided on each elastic component.

[0010] Furthermore, the moving component includes first sliding grooves provided on the left and right side walls of the hollow cavity, a first sliding block is provided inside each of the first sliding grooves, and one side of the first sliding block is connected to the second connecting plate.

[0011] Furthermore, the movable component includes a second slide groove opened on the top of the base, a fixed shaft is provided inside the second slide groove, a second slider is movably sleeved on the fixed shaft, and the top of the second slider is connected to the wedge-shaped fixed block.

[0012] Furthermore, the telescopic assembly includes an electric telescopic rod arranged on the inner wall of the bottom of the hollow cavity, and the telescopic end of the electric telescopic rod is connected to the first connecting plate.

[0013] Furthermore, the elastic component includes a hollow cylinder arranged on one side of the wedge-shaped fixed block, a spring is arranged inside the hollow cylinder, a piston disk is arranged on one side of the spring, a movable rod is arranged on one side of the piston disk, and the end of the movable rod away from the piston disk passes through the hollow cylinder and is connected to the fixed disk.

[0014] Furthermore, a first anti-slip surface is provided on the fixing plate.

[0015] The technical effects achieved by this utility model are:

[0016] When the positioning fixture is activated, the metal fitting is first placed on the carrier plate. The telescopic assembly then begins to retract. The contraction of the telescopic assembly drives the first connecting plate downward. Because the first meshing teeth on either side of the first connecting plate mesh with the gears, the upward and downward movement of the first connecting plate causes the gears to rotate. The rotation of the gears further drives the meshed second connecting plate to smoothly move horizontally via the movable assembly. As the second connecting plate moves horizontally, the third connecting plate connected to it moves accordingly within the through-hole. As the third connecting plate moves, the first wedge block on one side of the third connecting plate comes into contact with the wedge-shaped fixed block, engaging it. As the first wedge block continues to move, it pushes the wedge-shaped fixed block to one side via the movable assembly, thereby compressing the elastic assembly. As the elastic assembly compresses, the fixed plate to which it is connected gradually approaches the metal fitting, ultimately firmly clamping it. Conversely, when the telescopic assembly extends, driving the above components in the opposite direction, the fixed plate loosens its grip on the metal fitting, enabling precise positioning and flexible clamping and loosening of the metal fitting. This device not only achieves more precise positioning and clamping, reducing processing errors caused by improper clamping, but also can adapt to metal accessories of different sizes and shapes.

[0024] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0025] like Figure 1-5 As shown, the technical solution adopted by the present invention is specifically as follows: a metal accessory positioning fixture, comprising a base 1, a carrying plate 2 for carrying the metal accessory is provided at the top center position of the base 1, and a hollow cavity 3 is opened inside the base 1, a telescopic component is provided on the bottom inner wall of the hollow cavity 3, a first connecting plate 4 is provided on the top of the telescopic component, and first meshing teeth 5 are provided on both sides of the first connecting plate 4, a rotating shaft 6 is rotatably provided on the front and rear side walls of the hollow cavity 3, a gear 7 meshing with the first meshing teeth 5 is fixedly sleeved on the rotating shaft 6, a moving component is provided on the left and right side walls of the hollow cavity 3, a second connecting plate 8 is provided on the moving component, and a second meshing tooth 9 meshing with the gear 7 is provided on one side of the second connecting plate 8;

[0026] Two through holes 10 and two movable components are provided on the top of the base 1. A third connecting plate 11 is movably provided inside each through hole 10. The bottom of the third connecting plate 11 is connected to the second connecting plate 8. A first wedge block 12 is provided on one side of the third connecting plate 11. A wedge-shaped fixing block 13 matching the first wedge block 12 is provided on each movable component. A plurality of elastic components are provided on one side of the wedge-shaped fixing block 13, and a fixing plate 14 is provided on each elastic component.

[0027] The moving assembly includes first chutes 15 provided on the left and right side walls of the hollow cavity 3 . A first slider 16 is provided inside each first chute 15 , and one side of the first slider 16 is connected to the second connecting plate 8 .

[0028] When the gear 7 rotates, it engages with the second meshing teeth 9 on the second connecting plate 8, thereby driving the second connecting plate 8 to move left and right. The movement of the second connecting plate 8 drives the first slider 16 connected to it to slide in the first slide groove 15, so that the second connecting plate 8 and the third connecting plate 11 connected to it can achieve stable movement, providing reliable support for the positioning and fixation of metal accessories.

[0029] At the same time, the movable component includes a second slide groove 17 opened on the top of the base 1, a fixed shaft 18 is provided inside the second slide groove 17, and a second slider 19 is movably sleeved on the fixed shaft 18. The top of the second slider 19 is connected to the wedge-shaped fixed block 13. When the wedge-shaped fixed block 13 moves, the second slider 19 is driven to move on the fixed shaft 18. This arrangement realizes the flexible movement of the wedge-shaped fixed block 13 and provides additional adaptability and stability for the positioning and fixation of metal accessories.

[0030] The telescopic assembly includes an electric telescopic rod 20 provided on the inner wall of the bottom of the hollow cavity 3, and the telescopic end of the electric telescopic rod 20 is connected to the first connecting plate 4. The electric telescopic rod 20 drives the first connecting plate 4 to move up and down, thereby performing work.

[0031] The elastic assembly includes a hollow cylinder 21 disposed on one side of the wedge-shaped fixed block 13. A spring 22 is disposed inside the hollow cylinder 21. A piston disc 23 is disposed on one side of the spring 22. A movable rod 24 is disposed on one side of the piston disc 23. The end of the movable rod 24, away from the piston disc 23, extends through the hollow cylinder 21 and is connected to the fixed disc 14. When the wedge-shaped fixed block 13 moves, the fixed disc 14 first contacts the metal fitting. Since the fixed disc 14 is connected to the movable rod 24, the fixed disc 14 drives the movable rod 24 to move together. The movement of the movable rod 24 causes the piston disc 23 to squeeze the spring 22, thereby deforming the spring 22. Through the deformation of the spring 22, the elastic assembly can adapt to metal fittings of different sizes. When encountering metal fittings of different shapes, since multiple sets of fixed discs 14 are provided, each set of fixed discs 14 can adapt to the shape of the metal fitting through the deformation of the spring 22. In this way, the elastic assembly can fasten and position metal fittings of different shapes and sizes.

[0032] The fixing plate 14 is provided with a first anti-slip surface, which can increase friction and improve the fixing effect.

[0033] At the same time, a second anti-slip surface is provided on the carrying plate, which can increase the friction force and improve the fixing effect.

[0034] The working principle of this practical device is as follows: When the positioning fixture is activated, the metal fitting is first placed on the support plate 2. The telescopic assembly then begins to retract. The contraction of the telescopic assembly drives the first connecting plate 4 downward. Since the first meshing teeth 5 on both sides of the first connecting plate 4 mesh with the gear 7, the up and down movement of the first connecting plate 4 causes the gear 7 to rotate. The rotation of the gear 7 further drives the meshed second connecting plate 8 to move smoothly horizontally via the movable assembly. As the second connecting plate 8 moves horizontally, the connected third connecting plate 11 moves accordingly within the through hole 10. As the third connecting plate 11 moves, the first wedge block 12 on one side of the third connecting plate 11 contacts and interacts with the wedge-shaped fixed block 13. As the first wedge block 12 continues to move, it pushes the wedge-shaped fixed block 13 to one side via the movable assembly, thereby compressing the elastic assembly. As the elastic assembly is compressed, the fixed plate 14 to which it is connected gradually approaches the metal fitting, ultimately firmly clamping it. Conversely, when the telescopic assembly extends, driving the aforementioned components in the opposite direction, the fixed plate 14 loosens its grip on the metal fitting, enabling precise positioning and flexible clamping and loosening of the metal fitting. This device not only achieves more precise positioning and clamping, reducing machining errors caused by improper clamping, but also accommodates metal fittings of varying sizes and shapes.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
