Description
Technical Field
[0001] This utility model relates to the field of tooling fixture technology, and in particular to a machine tool tooling fixture. Background Technology
[0002] In the machining industry, tooling fixtures are a fundamental and crucial technology, undertaking the key tasks of workpiece fixation and positioning. Their existence ensures that the workpiece maintains a stable posture and precise position during machining, playing an irreplaceable role in ensuring machining accuracy and production efficiency. At the same time, the application of tooling fixtures significantly reduces the labor intensity of operators, improves the level of production automation, and thus brings significant economic benefits to enterprises while enhancing product quality.
[0003] Traditional tooling fixtures are typically designed for workpieces of specific dimensions, with their structure and dimensions custom-made to the characteristics of these workpieces. While this design approach enables efficient clamping of specific workpieces, it often faces the challenge of dealing with a wide variety of workpiece specifications in actual production. Existing tooling fixtures often prove inadequate when handling workpieces of different sizes and shapes, and cannot be flexibly adjusted to adapt to the needs of various workpiece specifications. Utility Model Content
[0004] The purpose of this utility model is to provide a machine tool fixture that can clamp workpieces of different sizes and shapes according to actual needs, and at the same time greatly improve the flexibility of the fixture.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A machine tool fixture, comprising,
[0007] Mounting frame;
[0008] Mounting plates are inclinedly disposed on both sides of the mounting frame;
[0009] A mounting sleeve is provided on one side of the mounting plate;
[0010] The clamping component is slidably fitted onto the mounting sleeve;
[0011] A drive assembly is disposed on the mounting frame. The output end of the drive assembly passes through the mounting frame and is hinged to the clamping assembly. The drive assembly is used to drive the two corresponding clamping assemblies to move closer together to clamp the workpiece.
[0012] According to some embodiments, the clamping assembly includes:
[0013] The slider is fitted onto the mounting sleeve;
[0014] A connecting plate is located on one side of the slider;
[0015] The first connecting rod is located on one side of the connecting plate;
[0016] A clamping block is located at one end of the first connecting rod;
[0017] The connecting plate is hinged to the drive assembly.
[0018] According to some embodiments, the driving component includes:
[0019] An electric push rod is located inside the mounting frame. The output end of the electric push rod passes through the mounting frame and is connected to a fixing block. A second connecting rod is rotatably connected to both sides of the fixing block. One end of the second connecting rod is rotatably connected to the connecting plate.
[0020] According to some embodiments, a limit plate is provided on one side of the slider.
[0021] According to some embodiments, the connecting plate is provided with an installation groove, and a column is provided in the installation groove. The first connecting rod is rotatably sleeved on the column. A first limiting post is provided on one side of the column, and a tension spring is provided between the first limiting post and the first connecting rod.
[0022] According to some embodiments, a second limiting post is provided between the column and the first limiting post, and one side of the first connecting rod is in contact with the second limiting post.
[0023] According to some embodiments, the opposite sides of the two clamping blocks have an arc-shaped structure.
[0024] Beneficial effects:
[0025] 1. By having a driving component on the mounting frame and sliding the clamping component on the mounting frame, the clamping component can be driven by the driving component to achieve precise clamping of workpieces of different sizes.
[0026] 2. By setting mounting plates at an angle on both sides of the mounting frame and sleeve the clamping components on the mounting sleeve, the mounting plates and mounting sleeve will guide the clamping components to move along their inclined path as the driving component performs the clamping movement. This serves as a sliding track for the clamping components. Only during this inclined movement can the corresponding clamping components achieve a relatively close effect, thus achieving precise clamping of workpieces of different sizes. This also greatly increases the adjustment range and flexibility of the fixture.

[0036] Combination Figure 1 and Figure 2 As shown, a machine tool fixture includes a mounting frame 1, a mounting plate 2, a mounting sleeve 3, a clamping assembly 4, and a driving assembly 5.
[0037] Mounting plate 2 is inclined on both sides of mounting frame 1; mounting sleeve 3 is located on one side of mounting plate 2; clamping assembly 4 is slidably mounted on mounting sleeve 3; driving assembly 5 is located on mounting frame 1, the output end of driving assembly 5 passes through mounting frame 1 and is hinged to clamping assembly 4, driving assembly 5 is used to drive the two corresponding clamping assemblies 4 to approach each other to clamp the workpiece.
[0038] The design incorporates a drive assembly 5 on the mounting frame 1, with the clamping assembly 4 slidably mounted on the frame 1. Driven by the drive assembly 5, it enables precise clamping of workpieces of different sizes. Furthermore, by installing mounting plates 2 at an angle on both sides of the mounting frame 1, and fitting the clamping assembly 4 onto mounting sleeves 3, the drive assembly 5, while driving the clamping assembly 4, guides the clamping assembly 4 along its inclined path, serving as a sliding track. Only during this inclined movement can the clamping assembly 4 achieve a relatively close proximity, thus enabling precise clamping of workpieces of different sizes and significantly increasing the adjustment range and flexibility of the fixture.
[0039] Specifically, the clamping assembly 4 includes: a slider 41, a connecting plate 42, a first connecting rod 43, and a clamping block 44. The slider 41 is sleeved on the mounting sleeve 3; the connecting plate 42 is located on one side of the slider 41; the first connecting rod 43 is located on one side of the connecting plate 42; the clamping block 44 is located at one end of the first connecting rod 43; the connecting plate 42 is hinged to the driving assembly 5.
[0040] When it is necessary to clamp the workpiece, the drive assembly 5 is activated. Since the output end of the drive assembly 5 pushes the connecting plate 42 through the hinge point, the connecting plate 42 is pushed and drives the slider 41 connected to it to slide in the mounting sleeve 3. The slider 41 slides along the inclined mounting plate 2 in the mounting sleeve 3. This inclined design allows the slider 41 to move simultaneously in the horizontal and vertical directions. As the slider 41 moves, the first connecting rod 43 connected to the connecting plate 42 is also driven. The other end of the first connecting rod 43 is connected to the clamping block 44, so the clamping block 44 moves accordingly. Due to the inclined design of the mounting plate 2, the movement of the slider 41 causes the clamping block 44 to gradually approach the workpiece. Finally, the clamping block 44 contacts the workpiece and applies clamping force to firmly fix the workpiece.
[0041] Combination Figure 1 As shown, the drive assembly 5 includes: an electric push rod 51, a fixing block 52, and a second connecting rod 53. The electric push rod 51 is located inside the mounting frame 1. The output end of the electric push rod 51 passes through the mounting frame 1 and is connected to the fixing block 52. The two sides of the fixing block 52 are respectively rotatably connected to the second connecting rod 53, and one end of the second connecting rod 53 is rotatably connected to the connecting plate 42.
[0042] When a workpiece needs to be clamped, the electric push rod 51 is activated and begins to extend. The output end of the electric push rod 51 pushes the fixed block 52, causing it to move along the axis of the electric push rod. The movement of the fixed block 52 drives the second connecting rods 53 on both sides to rotate. One end of the second connecting rod 53 is rotatably connected to the connecting plate 42. Therefore, the rotation of the second connecting rod 53 will drive the connecting plate 42 to move. The movement of the connecting plate 42 is transmitted to the clamping block 44 through the first connecting rod 43, causing the clamping block 44 to move towards the workpiece. Finally, the clamping block 44 contacts the workpiece and applies clamping force to firmly fix the workpiece.
[0043] Further reference Figure 2 As shown, a limiting plate 411 is provided on one side of the slider 41. The limiting plate 411 can limit the movement distance and direction of the slider 41, ensuring that the slider 41 can only move on a predetermined track or path. This can prevent the slider 41 from moving excessively, which could cause the slider 41 to detach from the mounting sleeve 3.
[0044] Combination Figure 2 As shown, the connecting plate 42 has an installation groove 421, and a column 422 is provided in the installation groove 421. The first connecting rod 43 is rotatably sleeved on the column 422. A first limiting post 423 is provided on one side of the column 422, and a tension spring 424 is provided between the first limiting post 423 and the first connecting rod 43.
[0045] The combination of the mounting groove 421, column 422, first limiting post 423 and tension spring 424 on the connecting plate 42 serves to prevent over-clamping of the workpiece. When the clamping block 44 contacts the workpiece and applies clamping force, the first connecting rod 43 will rotate relative to the connecting plate 42 under the action of the tension spring 424 until the first connecting rod 43 contacts the first limiting post 423, while the tension spring 424 will be in a stretched state.
[0046] Further reference Figure 2 As shown, a second limiting post 425 is provided between the column 422 and the first limiting post 423, and one side of the first connecting rod 43 is in contact with the second limiting post 425.
[0047] This ensures that, under the action of the second limiting post 425, when the clamping block 44 releases the workpiece, until the first connecting rod 43 comes into contact with the second limiting post 425, the first connecting rod 43 and the connecting plate 42 will not continue to rotate relative to each other due to the action of the tension spring 424.
[0048] To further explain, the two clamping blocks 44 have an arc-shaped structure on opposite sides, which allows them to better adapt to the structure of the workpiece and clamp it.
[0049] The working principle of this utility model is as follows:
[0050] When it is necessary to clamp the workpiece, the electric push rod 51 of the drive assembly 5 is activated. The output end of the electric push rod 51 pushes the fixed block 52. The movement of the fixed block 52 drives the second connecting rod 53 to rotate. One end of the second connecting rod 53 is rotatably connected to the connecting plate 42, causing the connecting plate 42 to move. The movement of the connecting plate 42 is transmitted to the clamping block 44 through the first connecting rod 43. The clamping block 44 moves towards the workpiece. When the clamping block 44 contacts the workpiece, due to the action of the tension spring 424, the first connecting rod 43 and the connecting plate 42 rotate relative to each other until the first connecting rod 43 contacts the first limiting post 423, ensuring that the clamping force is appropriate. The arc-shaped structure of the clamping block 44 allows it to better adapt to the surface of the workpiece, ensuring that the workpiece is firmly clamped.
[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
