Description
Technical Field
[0001] This utility model relates to the field of machining fixture technology, specifically a positioning fixture for metal parts. Background Technology
[0002] Metal parts refer to a collective term for metal blocks, metal rods, and metal tubes of various specifications and shapes made of metal materials. When processing metal parts, a variety of jigs are required to process them so that the metal parts can achieve the required shape.
[0003] A jig is a special tool used in mass production to fix (clamp) products for processing (assembly) and to inspect product quality.
[0004] In the prior art, such as the Chinese patent with authorization announcement number CN209465969U entitled "A Positioning Fixture for Metal Part Processing", the aforementioned patent discloses a positioning fixture for metal part processing, including a base and a fixing plate located on the upper outer surface of the base and fixedly connected to one side of the base, and a sliding clamp located in front of the fixing plate. A support rod is provided on one side of the outer surface of the sliding clamp, and a pad is sleeved on one end of the support rod. Openings are provided on both sides of the outer surface of the fixing plate, and positioning screws are provided on the outer surface of the fixing plate. A fixing sleeve is provided behind the fixing plate.

[0005] Existing technologies, including the aforementioned patents, offer some convenience for operators, facilitating the clamping and positioning of metal parts of varying sizes and maintaining their stability during processing. It is evident that during metal part processing, the metal part is typically placed inside a processing groove within a fixture, and then secured by a fastening unit. However, in this process, the metal part comes into contact with the inner wall of the processing groove on the fixture, and the fastening unit further compresses the metal part during its travel, potentially causing surface damage to the metal part, thus presenting certain shortcomings.

[0027] 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.
[0028] Please see Figures 1-7 This utility model provides a technical solution: a metal part positioning fixture, including a support plate 1, a plurality of positioning posts 4 are installed on the support plate 1, and a plurality of workpieces 2 are installed on the support plate 1 through the positioning posts 4. The workpieces 2 are provided with through holes. When the workpieces 2 are installed on the support plate 1, the positioning posts 4 position the workpieces 2 through the through holes; a positioning unit is also provided between the support plate 1 and the workpieces 2.
[0029] Specifically, this metal part positioning fixture includes a support plate 1, on which multiple sets of positioning pins 4 are mounted, and multiple workpieces 2 are mounted on the support plate 1 via the positioning pins 4. The workpieces 2 have through holes; more specifically, the through holes are an essential feature of the workpieces 2 to meet the needs of later use. When the workpieces 2 are mounted on the support plate 1, the positioning pins 4 position them through the through holes. A positioning unit is also provided between the support plate 1 and the workpieces 2. This positioning unit positions the workpieces 2. During use, after the workpieces 2 are mounted on the support plate 1, they are then mounted on the positioning pins 4. Afterwards, specific equipment is used for metal processing. During the positioning of the workpieces 2 using this fixture, the outer side of the workpieces 2 does not contact the periphery of the workpieces 2, but rather abuts against the through holes on the workpieces 2 via the positioning pins 4. Clearly, during processing, the workpieces 2 can be positioned without damaging their sidewalls, thus meeting the processing requirements of the workpieces 2.
[0030] In the embodiments provided by this utility model, each positioning post 4 is slidably connected to the support plate 1. Therefore, when it is necessary to remove the workpiece 2 from the support plate 1, it is only necessary to move the positioning post 4 downward into the support plate 1 to release the restriction on the workpiece 2, making it more convenient to install and remove the workpiece 2. The multiple sets of positioning posts 4 are connected by connecting members 5, which can further improve the sliding efficiency of the positioning posts 4.
[0031] In the embodiments provided by this utility model, the connecting member includes a connecting rod 51 fixedly connected to the bottom of the positioning post 4. Two adjacent connecting rods 51 are fixedly connected by a connecting plate 52, and a force-bearing plate 53 is provided between multiple connecting plates 52. Two adjacent force-bearing plates 53 are fixedly connected by a driving plate 54, and a positioning member is provided between the driving plate 54 and the bearing plate 1. When the driving plate 54 slides, it will drive all the positioning posts 4 to slide together, improving the sliding efficiency of the positioning posts 4 and facilitating the installation and disassembly of the workpiece 2.
[0032] In the embodiments provided by this utility model, the positioning component includes a pressure spring 6. The elastic force of the pressure spring 6 drives the positioning post 4 to engage in the through hole. The elastic force of the pressure spring 6 enables the positioning post 4 to maintain a predetermined state, thus meeting the working requirements.
[0033] In the embodiment provided by this utility model, a power rod 10 is fixedly connected to the force plate 53. The power rod 10 is slidably connected to the bearing plate 1. Specifically, when it is necessary to drive the positioning column 4 to move downward, the power rod 10 will drive the drive plate 54 to move downward together, thereby making multiple sets of positioning columns 4 slide together, improving the sliding efficiency of the positioning column 4, and facilitating the installation and disassembly of the workpiece 2.
[0034] In the embodiment provided by this utility model, a positioning frame 7 is fixedly connected inside the bearing plate 1. A locking part is also provided between the positioning frame 7 and the drive plate 54. The locking part includes a locking rod fixedly connected to the positioning frame 7. A conical block 8 is fixedly connected to the locking rod. An adaptation groove 9 that matches the conical block 8 is opened on the bottom of the drive plate 54. The conical block 8 and the adaptation groove 9 are interference-fitted. That is, when it is necessary to remove the workpiece 2 from the bearing plate 1, the power rod 10 is pressed down. The power rod 10 drives the drive plate 54 to slide down. At this time, the conical block 8 will be locked inside the adaptation groove 9. The friction between the conical block 8 and the adaptation groove 9 can insert the positioning post 4 into the adaptation groove 9, thereby restricting the state of the positioning post 4. Furthermore, the friction between the conical block 8 and the adapter groove 9 is greater than the elastic force of the pressure spring 6. Therefore, when the conical block 8 is engaged inside the adapter groove 9, the pressure spring 6 cannot drive the conical block 8 to slide out of the adapter groove 9, thus meeting the working requirements.
[0035] In the embodiments provided by this utility model, the conical block 8 is made of elastic material, which further meets the working requirements.
[0036] In the embodiments provided by this utility model, the positioning unit includes a vacuum adsorption component, and multiple sets of air intakes 3 are provided on the support plate 1. The air intakes 3 are connected to the vacuum adsorption component, thereby further improving the stability of the workpiece 2 during installation.
[0037] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.
[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
