Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts clamping technology, specifically relating to mechanical parts clamping fixtures with adaptive clamping function. Background Technology

[0002] A fixture, also known as a jig, is a device used in mechanical manufacturing to fix a workpiece in the correct position for trial work or inspection. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process can be called a fixture. The main function of a fixture is to ensure the stability and accuracy of the workpiece during machining, thereby improving machining precision and production efficiency.

[0003] Mechanical component fixtures are used to determine the correct position of workpieces within the fixture, ensuring their stability during machining. They are used to clamp workpieces and prevent them from moving or deforming during processing. Traditional methods using mechanical component fixtures typically rely on a lateral movement mechanism to control the clamping plate for precise assembly and clamping of mechanical components. However, given the diverse sizes and specifications of mechanical components, this traditional method proves inadequate for parts of varying dimensions and shapes. Specifically, when the dimensions of the components to be clamped change, traditional lateral movement clamping methods may require tedious manual adjustments or repositioning. This not only increases operational complexity but can also lead to decreased clamping accuracy, ultimately impacting overall production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical component clamping fixture with adaptive clamping function. This addresses the problem that existing mechanical component clamping fixtures typically rely on a lateral movement mechanism to control the clamping plate for precise assembly and clamping of mechanical components. However, given the diverse sizes and specifications of mechanical components, this traditional method is inadequate for handling parts of varying dimensions and shapes. Specifically, when the dimensions of the clamped component change, the traditional lateral movement clamping method may require cumbersome manual adjustments or repositioning. This not only increases operational complexity but may also lead to decreased clamping accuracy, ultimately affecting overall production efficiency and product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanical parts clamp with adaptive clamping function, comprising a clamp base plate and a support plate mounted on the surface of the clamp base plate, wherein an mounting plate is mounted on the surface of the support plate, and a clamping platform is mounted on the center surface of the support plate;

[0006] The mounting plate has a slide rail connected to its surface, a sliding block movably connected to the slide rail, a limit block connected to the bottom surface of the sliding block, a hydraulic cylinder connected to one side of the limit block, a cylinder placement box installed at one end of the support plate, a fixing block connected to the surface of the sliding block, a threaded rod penetrating one side of the fixing block, a receiving block connected to one end of the threaded rod, a pushing block connected to the other side of the receiving block, and a clamping assembly installed on the surface of the mounting plate.

[0007] As a preferred embodiment of the mechanical component clamping fixture with adaptive clamping function of this utility model, the sliding block forms a sliding connection structure with the opening on the surface of the slide rail through the limiting block, and the threaded rod is threadedly connected to the fixed block.

[0008] As a preferred embodiment of the mechanical component clamping fixture with adaptive clamping function of this utility model, a rotating block is connected to one end of the threaded rod near the receiving block, and the rotating block and the opening on one side of the receiving block form a rotating structure.

[0009] As a preferred mechanical component clamping fixture with adaptive clamping function of this utility model, the clamping assembly includes a support frame, a rotating plate, rollers and a pressure plate. The support frame is mounted on the surface of the mounting plate, and the rotating plate is rotatably connected to the top of the support frame.

[0010] As a preferred mechanical component clamping fixture with adaptive clamping function of this utility model, one end of the rotating plate is rotatably connected to a roller, and the other end of the rotating plate is connected to a pressure plate.

[0011] As a preferred embodiment of the mechanical component clamping fixture with adaptive clamping function of this utility model, the end of the pressure plate near the rotating plate is connected to an assembly plate, the inner walls of the openings on both sides of the assembly plate are connected to reciprocating springs, and the other end of the reciprocating springs is connected to a buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention places the mechanical workpiece on a clamping table, then controls a hydraulic cylinder to drive a sliding block to slide along a slide rail, causing the clamping assembly on the mounting plate surface to move onto the mechanical workpiece. Next, the threaded rod on the surface of the fixed block is rotated, causing the push block at the other end of the threaded rod to advance towards the rotating plate. At this time, the roller on the surface of the push block rotates and rises, thereby causing the rotating plate to rotate along the support frame. The pressure plate then clamps the mechanical workpiece stably. After the mechanical parts clamp is adjusted laterally, the clamping assembly is readjusted, facilitating the adjustment of the clamping size and enabling adaptive clamping of the mechanical workpiece, thus improving the practicality of the mechanical parts clamp.

[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] Please see Figure 1-5 The present invention provides the following technical solution: a mechanical parts clamp with adaptive clamping function, including a clamp base plate 1 and a support plate 2 installed on the surface of the clamp base plate 1, an mounting plate 3 installed on the surface of the support plate 2, and a clamping table 4 installed on the center surface of the support plate 2;

[0023] The surface of the mounting plate 3 is connected to a slide rail 5, the surface of the slide rail 5 is movably connected to a sliding block 6, the bottom surface of the sliding block 6 is connected to a limit block 7, one side of the limit block 7 is connected to a hydraulic cylinder 8, one end of the support plate 2 is equipped with a cylinder placement box 9, the surface of the sliding block 6 is connected to a fixing block 10, one side of the fixing block 10 is connected to a threaded rod 11, one end of the threaded rod 11 is connected to a receiving block 12, the other side of the receiving block 12 is connected to a pushing block 14, and the surface of the mounting plate 3 is equipped with a clamping assembly.

[0024] Preferably, the sliding block 6 forms a sliding connection structure with the opening on the surface of the slide rail 5 through the limiting block 7, and the threaded rod 11 is threadedly connected to the fixed block 10.

[0025] In practical use, the sliding block 6 slides along the opening on the surface of the slide rail 5, which facilitates the directional movement of the sliding block 6.

[0026] Preferably, a rotating block 13 is connected to one end of the threaded rod 11 near the receiving block 12, and the rotating block 13 and the opening on one side of the receiving block 12 form a rotating structure.

[0027] In practical use, by rotating the threaded rod 11, the rotating block 13 can be easily rotated along the opening of the receiving block 12, which in turn facilitates the movement and adjustment of the pushing block 14.

[0028] Preferably, the clamping assembly includes a support frame 15, a rotating plate 16, a roller 17, and a pressure plate 18. The support frame 15 is mounted on the surface of the mounting plate 3, and the rotating plate 16 is rotatably connected to the top of the support frame 15.

[0029] In practical use, by rotating the rotating plate 16 along the support frame 15, it is convenient to drive the pressure plate 18 to press down, thereby making it convenient for the pressure plate 18 to clamp the mechanical parts.

[0030] Preferably, a roller 17 is rotatably connected to one end of the rotating plate 16, and a pressure plate 18 is connected to the other end of the rotating plate 16.

[0031] In practical use, the quick disassembly and assembly of the rotating plate 16 facilitates the replacement of pressure plates 18 of different models or different specifications and sizes, making it convenient to clamp and stabilize mechanical parts.

[0032] Preferably, the pressure plate 18 is connected to an assembly plate 19 at one end near the rotating plate 16, and reciprocating springs 20 are connected to the inner walls of the openings on both sides of the assembly plate 19. The other end of the reciprocating springs 20 is connected to a buckle 21.

[0033] In practical use, by pressing the buckle 21 against the reciprocating spring 20, the buckle 21 can be moved, which in turn makes it easier to install the pressure plate 18 on one end of the rotating plate 16 for convenient use.

[0034] Working principle: First, the mechanical workpiece is placed on the clamping table 4. Then, the hydraulic cylinder 8 is controlled to drive the sliding block 6 to slide along the slide rail 5, so that the clamping assembly on the surface of the mounting plate 3 moves onto the mechanical workpiece. Then, the threaded rod 11 on the surface of the fixed block 10 is rotated, which drives the push block 14 at the other end of the threaded rod 11 to advance towards the rotating plate 16. At this time, the roller 17 on the surface of the push block 14 rotates and rises, thereby driving the rotating plate 16 to rotate along the support frame 15. At this time, the pressure plate 18 clamps and stabilizes the mechanical workpiece. After the mechanical parts clamp is adjusted left and right, the clamping assembly is adjusted again to facilitate the adjustment of the clamping. The dimensions facilitate adaptive clamping of mechanical workpieces, enhancing the practicality of mechanical component clamping. Furthermore, by aligning the assembly plate 19 at one end of the pressure plate 18 with the opening at one end of the rotating plate 16, the latch 21 compresses the reciprocating spring 20. When the pressure plate 18 and the rotating plate 16 are stably aligned, the reciprocating spring 20 rebounds, causing the latch 21 to engage at the side opening of the rotating plate 16, achieving rapid assembly. Additionally, a pry bar applies force to the side opening of the rotating plate 16, facilitating the quick removal of the pressure plate 18 and allowing for easy replacement with different models or sizes of pressure plates 18, thus ensuring stable clamping of mechanical components.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
