Abstract
Description
Technical Field
[0001] This utility model relates to a tooling fixture, specifically a tooling fixture with multi-point support function, belonging to the field of machining technology. Background Technology
[0002] Tooling fixtures are designed to ensure the machining process in machining operations. Many processes cannot be achieved with the existing level of mechanical equipment, so auxiliary equipment or tools must be used to clamp and position the tools, i.e., tooling fixtures, such as welding clamps and machine tool clamps. Tooling, or process equipment, refers to the general term for all kinds of tools used in the manufacturing process, including cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter's tools, workstation equipment, etc.
[0003] In the prior art, such as the anti-slip tooling fixture disclosed in announcement number CN217966729U, a threaded rod is screwed into the inner wall of the first threaded hole, and then the threaded rod will move forward until it moves into the inner wall of the second threaded hole, at which point the vertical plate is limited, thus protecting the side of the object and preventing it from sliding under force. The above-mentioned prior art solution has the following shortcomings: In the process of use, the tooling fixture can play a good anti-slip role, but the clamping plate and the vertical plate of the fixture body can play a limiting role. However, when encountering irregular workpieces or uneven workpiece surfaces during machining, grinding or drilling, it is necessary to replace the clamping plate according to the specific machining requirements, which leads to unstable clamping during machining. Utility Model Content
[0004] The purpose of this utility model is to provide a tooling fixture with multi-point support function in order to solve at least one of the above-mentioned technical problems.
[0005] The present invention achieves the above objectives through the following technical solution: a tooling fixture with multi-point support function, comprising a support platform and a support plate mounted on the surface of the support platform;
[0006] The inner side of the support plate is symmetrically provided with clamping support components. The clamping support components include fixed plates symmetrically provided on the inner side of the support plate. A lower clamping block is fixedly installed on one side of the fixed plate, and an upper clamping block is provided on one side of the fixed plate and above the lower clamping block. An adjusting screw is rotatably connected to the surface of the fixed plate, and the upper clamping block is threadedly connected to the surface of the adjusting screw.
[0007] As a further embodiment of this utility model: a slider is fixedly installed on one side of the fixing plate, and a slide rail is slidably connected to the surface of the slider, and the slide rail is fixedly installed on the inner side of the support plate.
[0008] As a further embodiment of this utility model: a clamping block is provided on one side of both the upper clamping block and the lower clamping block, and a first arc block is integrally formed on one side of each clamping block. Both clamping blocks are rotatably connected to the first arc groove opened on one side of the upper clamping block and the lower clamping block respectively through the first arc block.
[0009] As a further improvement of this utility model: a guide rod is fixedly installed on one side of the upper clamping block, and the guide rod is slidably connected to a through hole on the surface of the fixing plate.
[0010] As a further embodiment of this utility model: a limiting component is installed on the surface of the slider. The limiting component includes an L-shaped fixing plate fixedly installed on the surface of the slider. A T-shaped insert is slidably connected in a through hole on the surface of the L-shaped fixing plate. One end of the T-shaped insert passes through the L-shaped fixing plate and is inserted into a positioning hole opened in the side wall of the support platform.
[0011] As a further embodiment of this utility model: a guide sleeve is installed on the surface of the L-shaped fixing plate, the T-shaped insert is slidably connected in the guide sleeve, a slot is opened on the surface of the guide sleeve, a number of positioning holes are opened on the side wall of the bearing platform, a spring is sleeved on the surface of the T-shaped insert, one end of the spring abuts against the bottom surface of the L-shaped fixing plate, and the other end of the spring abuts against a boss integrally formed on the surface of the T-shaped insert.
[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model is equipped with a support component. In use, the workpiece is clamped between the upper and lower clamping blocks through the cooperation of multiple sets of upper and lower clamping blocks. The multi-point clamping support structure can fix the workpiece from multiple positions, making the workpiece more stable during processing and reducing displacement, shaking or vibration caused by external forces. This effectively ensures processing accuracy and ensures that the workpiece's dimensional accuracy and geometric tolerances meet the requirements. Multiple clamping points can make the workpiece more evenly stressed, avoiding workpiece deformation due to excessive stress at a single point, and further improving processing accuracy. The position of the fixing plate can be changed by sliding the slider according to the length of the workpiece. This evenly stressed fixing method is especially important for some thin-walled, slender or easily deformable workpieces.
[0014] When the upper and lower clamping blocks are in contact with the workpiece, the two clamping blocks that are rotatably set on the upper and lower clamping blocks can rotate on their own according to the shape of the workpiece, so that the clamping blocks can fit tightly against the surface of the workpiece. After adding the freely rotatable clamping blocks, it can better adapt to various irregular shapes of the workpiece, ensuring that the clamping blocks can fit tightly against the surface of the workpiece. No matter whether the surface of the workpiece is uneven, curved, or has a complex geometry, the best contact point can be found, thereby improving the clamping reliability and eliminating the need for frequent replacement of the chucks.
[0015] 2. This utility model is equipped with a limit component. According to the usage requirements, after the sliding slider changes the position of the fixing plate, the T-shaped plug can be inserted into the corresponding positioning hole. The spring provided can ensure that one end of the T-shaped plug can be stably inserted into the corresponding positioning hole, improving the positioning accuracy. By precisely adjusting the position of the support clamp, the workpiece can be accurately fixed in the ideal processing position, ensuring that the processing tool can process the workpiece in the correct position.

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. Example 1
[0023] like Figures 1 to 5 As shown, a tooling fixture with multi-point support function includes a support platform 1 and a support plate 11 mounted on the surface of the support platform 1.
[0024] The inner side of the support plate 11 is symmetrically provided with clamping support components 2. The clamping support components 2 include a fixing plate 23 symmetrically provided on the inner side of the support plate 11. A lower clamping block 26 is fixedly installed on one side of the fixing plate 23. An upper clamping block 25 is provided on one side of the fixing plate 23 and above the lower clamping block 26. An adjusting screw 24 is rotatably connected to the surface of the fixing plate 23. The upper clamping block 25 is threadedly connected to the surface of the adjusting screw 24.
[0025] The workpiece is clamped between the upper clamping block 25 and the lower clamping block 26. Through the cooperation of multiple sets of upper clamping blocks 25 and lower clamping blocks 26, the multi-point clamping support structure can fix the workpiece from multiple positions, making the workpiece more stable during processing and reducing displacement, shaking or vibration caused by external forces. This effectively ensures the processing accuracy and ensures that the workpiece's dimensional accuracy and geometric tolerances meet the requirements. Multiple clamping points can make the workpiece more evenly stressed, avoiding workpiece deformation due to excessive stress at a single point, and further improving the processing accuracy.
[0026] A slider 22 is fixedly installed on one side of the fixed plate 23. A slide rail 21 is slidably connected to the surface of the slider 22. The slide rail 21 is fixedly installed on the inner side of the support plate 11.
[0027] The position of the fixing plate 23 can be changed by sliding the slider 22 according to the length of the workpiece. This uniform force fixing method is especially important for some thin-walled, slender or easily deformable workpieces.
[0028] A clamping block 29 is provided on one side of the upper clamping block 25 and the lower clamping block 26. A first arc block 210 is integrally formed on one side of the clamping block 29. The two clamping blocks 29 are rotatably connected to the first arc groove 28 opened on one side of the upper clamping block 25 and the lower clamping block 26 through the first arc block 210.
[0029] When the upper clamping block 25 and the lower clamping block 26 are in contact with the workpiece, the two clamping blocks 29 rotatably set on the upper clamping block 25 and the lower clamping block 26 can rotate on their own according to the shape of the workpiece, so that the clamping blocks 29 can fit tightly against the surface of the workpiece. After adding the freely rotatable clamping blocks 29, it can better adapt to various irregular shapes of the workpiece, ensuring that the clamping blocks 29 can fit tightly against the surface of the workpiece. No matter whether the surface of the workpiece is uneven, curved or has a complex geometry, the best fitting point can be found, thereby improving the clamping reliability and eliminating the need for frequent replacement of the chucks.
[0030] A guide rod 27 is fixedly installed on one side of the upper clamping block 25. The guide rod 27 is slidably connected to the through hole on the surface of the fixing plate 23.
[0031] The movement of the upper clamping block 25 can be guided, thereby improving the stability of the upper clamping block 25 during the movement process. Example 2
[0032] In addition to all the technical features included in Embodiment 1, this embodiment also includes:
[0033] A limiting component 3 is installed on the surface of the slider 22. The limiting component 3 includes an L-shaped fixing plate 31 fixedly installed on the surface of the slider 22. A T-shaped insert rod 32 is slidably connected in a through hole on the surface of the L-shaped fixing plate 31. One end of the T-shaped insert rod 32 passes through the L-shaped fixing plate 31 and is inserted into a positioning hole 38 opened on the side wall of the support platform 1.
[0034] The T-shaped insert 32 is inserted into the corresponding positioning hole 38, and the spring 34 ensures that one end of the T-shaped insert 32 can be stably inserted into the corresponding positioning hole 38, improving the positioning accuracy. By precisely adjusting the position of the support clamp, the workpiece can be accurately fixed in the ideal processing position, ensuring that the processing tool can process the workpiece in the correct position.
[0035] A guide sleeve 36 is installed on the surface of the L-shaped fixing plate 31. The T-shaped insert rod 32 is slidably connected inside the guide sleeve 36. A slot 37 is opened on the surface inside the guide sleeve 36. Several positioning holes 38 are opened on the side wall of the support platform 1. A spring 34 is sleeved on the surface of the T-shaped insert rod 32. One end of the spring 34 abuts against the bottom surface of the L-shaped fixing plate 31, and the other end of the spring 34 abuts against the boss 35 integrally formed on the surface of the T-shaped insert rod 32.
[0036] Working principle: During use, the workpiece to be processed is placed on the surface of the support plate 11 on the surface of the bearing table 1, so that the workpiece is between the upper clamping block 25 and the lower clamping block 26. Then, by rotating the adjusting screw 24, the upper clamping block 25, which is threaded to its surface, is moved closer to the side until the workpiece is clamped between the upper clamping block 25 and the lower clamping block 26. Through the cooperation of multiple sets of upper clamping blocks 25 and lower clamping blocks 26, the multi-point clamping support structure can fix the workpiece from multiple positions, making the workpiece more stable during processing and reducing displacement, shaking or vibration caused by external forces. This effectively ensures the processing accuracy and ensures that the dimensional accuracy and geometric tolerances of the workpiece meet the requirements. Multiple clamping points can make the workpiece more evenly stressed, avoiding workpiece deformation due to excessive stress at a single point, and further improving the processing accuracy. The position of the fixing plate 23 can be changed by sliding the slider 22 according to the length of the workpiece. This evenly stressed fixing method is especially important for some thin-walled, slender or easily deformable workpieces.
[0037] When the upper clamping block 25 and the lower clamping block 26 are in contact with the workpiece, the two clamping blocks 29 rotatably set on the upper clamping block 25 and the lower clamping block 26 can rotate on their own according to the shape of the workpiece, so that the clamping blocks 29 can fit tightly against the surface of the workpiece. After adding the freely rotatable clamping blocks 29, it can better adapt to various irregular shapes of the workpiece, ensuring that the clamping blocks 29 can fit tightly against the surface of the workpiece. No matter whether the surface of the workpiece is uneven, curved or has a complex geometric shape, the best fitting point can be found, thereby improving the clamping reliability and eliminating the need for frequent replacement of the chucks.
[0038] According to the usage requirements, after the sliding slider 22 changes the position of the fixing plate 23, the T-shaped insert 32 can be inserted into the corresponding positioning hole 38. The spring 34 can ensure that one end of the T-shaped insert 32 can be stably inserted into the corresponding positioning hole 38, improving the positioning accuracy. By precisely adjusting the position of the support clamp, the workpiece can be accurately fixed in the ideal processing position, ensuring that the processing tool can process the workpiece in the correct position.
