Description

Technical Field

[0001] This utility model belongs to the field of production equipment technology, and in particular relates to a milling machine auxiliary fixing fixture and a milling machine. Background Technology

[0002] In the field of metal processing, specimen preparation is a crucial step in ensuring the accuracy and consistency of subsequent mechanical property testing. Double-sided milling machines, as highly efficient equipment for simultaneously machining both sides of a workpiece, are widely used in specimen processing. By moving two cutter heads along the Z-axis (X and Y axes), they achieve one-time cutting of the upper and lower surfaces of the workpiece, which not only improves processing efficiency but also reduces the accumulation of errors caused by multiple clamping operations.

[0003] However, existing double-sided milling machines still have many problems in practical applications. First, the samples are usually placed on the worktable in a stacked manner, lacking effective positioning and fixing devices, making it difficult to accurately center and align the samples before processing. Operators often rely on visual judgment or experience to estimate the sample positioning, which can easily cause uneven feed of the X-axis or Y-axis cutter head, leading to overload damage to the milling cutter or abnormal equipment shutdown. Second, due to inaccurate sample positioning, the work-hardened area generated by shearing may not be completely removed during processing, resulting in sample scrap. In addition, uneven stacking of samples may cause the entire machine to tip over, affecting processing continuity and safety, and reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an auxiliary tooling for precise positioning and placement of samples.

[0005] The objective of this utility model can be achieved through the following technical solution: a milling machine auxiliary fixing fixture, comprising:

[0006] A fixing plate, the fixing plate including an abutting surface, the abutting surface being used for contacting and connecting with the sample;

[0007] A limiting part is fixedly disposed on one side surface of the fixing plate, and there are two limiting parts. The two limiting parts are distributed along the length direction of one side surface of the fixing plate. The limiting part includes a supporting surface and a limiting surface. The limiting surface is used to abut against the mounting seat on the milling machine. The upper end surface of the supporting surface is not higher than the upper end surface of the mounting seat on the milling machine.

[0008] In the above-mentioned milling machine auxiliary fixing fixture, the limiting part includes an L-shaped limiting plate, the connecting end of the limiting plate is fixed to the fixing plate, and the abutting end of the limiting plate is a limiting surface used to abut against the mounting base.

[0009] In the above-mentioned milling machine auxiliary fixing fixture, an abutment plate is fixedly provided between the fixing plate and the limiting plate. The abutment plate and the limiting plate are arranged parallel to each other, and the abutment plate is used to abut and limit the mounting base.

[0010] In the above-mentioned milling machine auxiliary fixing fixture, the limiting part and the fixing plate are detachably fixedly connected, so that the fixing plate and the limiting part can be separated.

[0011] In the above-mentioned milling machine auxiliary fixing fixture, the limiting part and the fixing plate are connected and fixed by a connecting screw. The connecting screw passes through the fixing plate and the limiting part in sequence and is threadedly connected to the connecting nut, thereby fixing the fixing plate and the limiting part, and at the same time, making the two separable.

[0012] In the above-mentioned milling machine auxiliary fixing fixture, a rotating handle is hinged at the screw head of the connecting screw.

[0013] In the above-mentioned milling machine auxiliary fixing fixture, the fixing plate is provided with a fixing groove, and the connecting nut is fixedly installed in the fixing groove.

[0014] In the above-mentioned milling machine auxiliary fixing fixture, there are two connecting screws, and both connecting screws pass through the limiting part and are threadedly connected to the connecting nut.

[0015] In the above-mentioned milling machine auxiliary fixing fixture, a fixing bracket is also included. A support shaft is fixedly installed on the fixing bracket. Multiple hinge shafts are arranged linearly on the support shaft. Adjacent hinge shafts are hinged together, and the swing directions of the multiple hinge shafts are not parallel. The end hinge shaft is fixedly connected to the fixing plate.

[0016] A milling machine includes the aforementioned milling machine auxiliary fixture.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: two limiting parts are distributed along one side of the fixed plate, and the limiting surface is used to abut against the side of the mounting base, thereby realizing accurate positioning and stable installation of the tooling on the milling machine; the supporting surface on the limiting part can either abut against the sample to provide a stable positioning support for the sample, or be designed to be lower than the upper end surface of the mounting base to avoid affecting the installation and positioning of the sample on the mounting base. The mounting base realizes the vertical positioning of the sample, and by making close contact between the sample and the abutting surface of the fixed plate, the horizontal positioning of the sample can be realized. The two work together to achieve precise positioning and installation of the sample on the milling machine. Attached Figure Description

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] like Figures 1-4 As shown, a milling machine auxiliary fixing fixture includes:

[0026] The fixing plate 100 includes an abutting surface 101, which is used to make contact with the sample 501.

[0027] The limiting part 200 is fixedly disposed on one side of the fixing plate 100, and there are two limiting parts 200. The two limiting parts 200 are distributed along the length direction of one side of the fixing plate 100. The limiting part 200 includes a supporting surface 201 and a limiting surface 202. The limiting surface 202 is used to abut against the mounting seat 500 on the milling machine. The upper end surface of the supporting surface 201 is not higher than the upper end surface of the mounting seat 500 on the milling machine.

[0028] In this embodiment, two limiting parts 200 are distributed along one side of the fixing plate 100, and the limiting surface 202 is used to abut against the side of the mounting base 500, thereby realizing the accurate positioning and stable installation of the tooling on the milling machine. The supporting surface 201 on the limiting part 200 can either abut against the sample 501 to provide a stable positioning support for the sample 501, or it can be designed to be lower than the upper end surface of the mounting base 500 to avoid affecting the installation and positioning of the sample 501 on the mounting base 500. The mounting base 500 realizes the vertical positioning of the sample 501, and by making close contact between the sample 501 and the abutment surface 101 of the fixing plate 100, the sample 501 can be accurately positioned in the horizontal direction. The two work together to realize the precise positioning and installation of the sample 501 on the milling machine.

[0029] It should be noted that after the sample 501 is precisely positioned, the fixing plate 100 is moved out of the milling machine and will not occupy the working space of the milling machine.

[0030] In a further preferred embodiment, the limiting part 200 includes an L-shaped limiting plate, the connecting end of the limiting plate being fixed to the fixing plate 100, and the abutting end of the limiting plate being a limiting surface 202 for abutting against the mounting base 500.

[0031] In this embodiment, the L-shaped limiting plate, through its specific shape, reduces the direct contact area with the sample 501 and the mounting base 500, effectively avoiding the accumulation of minute deviations caused by large-area contact and ensuring higher processing accuracy. Due to the reduced contact area, the impact of dimensional changes caused by material thermal expansion and contraction, surface unevenness, or other factors on the processing is also minimized.

[0032] In a further preferred embodiment, an abutment plate 203 is fixedly provided between the fixed plate 100 and the limiting plate. The abutment plate 203 and the abutment end of the limiting plate are arranged parallel to each other. The abutment plate 203 is used to abut and limit the mounting base 500.

[0033] In this embodiment, by providing an abutment plate 203 between the fixed plate 100 and the limiting plate, and arranging it parallel to the abutment end of the limiting plate, a more stable connection can be provided for the mounting base 500. The ends of the limiting surface 202 and the abutment plate 203 simultaneously abut against the mounting base 500, which not only increases the rigidity of the overall structure but also ensures the precise positioning and stability of the tooling on the milling machine. The abutment plate 203 is used for abutment and limiting with the mounting base 500, and forms multiple contact points with the limiting surface 202, which helps to disperse the force and reduce deviations caused by excessive force at a single point. This multi-point contact method can effectively improve the positioning accuracy of the sample 501 and reduce machining errors.

[0034] Preferably, the limiting part 200 and the fixing plate 100 are detachably fixedly connected, allowing the fixing plate 100 and the limiting part 200 to be separated. This detachable design allows for quick replacement of the corresponding limiting part 200 according to different milling machine mounting bracket 500 intervals, improving the tooling's versatility and adaptability, enabling it to flexibly handle different models or specifications of milling machines. When a component (such as the limiting part 200 or the fixing plate 100) wears or is damaged, it can be easily replaced individually without replacing the entire tooling.

[0035] Specifically, the limiting part 200 and the fixing plate 100 are connected and fixed by a connecting screw 300. The connecting screw 300 passes through the fixing plate 100 and the limiting part 200 in sequence and is threadedly connected to the connecting nut 301, thereby fixing the fixing plate 100 and the limiting part 200, and at the same time, making the two separable.

[0036] Specifically, the connecting screw 300 passes sequentially through the connecting ends of the fixing plate 100, the abutment plate 203, and the limiting plate, and is then locked by the connecting nut 301 to fix the components together. The connection method of the screw and nut makes the disassembly and installation between the limiting part 200 and the fixing plate 100 simple and quick. The components can be easily separated simply by loosening the screw, which facilitates the quick replacement of the corresponding limiting part 200 according to different milling machine mounting base 500 intervals.

[0037] Preferably, a rotating handle 302 is hinged to the screw head of the connecting screw 300. The rotating handle 302 provides a larger torque application surface. Compared with directly rotating the screw head, the operator can perform tightening or loosening operations more effortlessly by manually rotating the handle 302, which greatly simplifies the installation and disassembly process and thus improves work efficiency.

[0038] Specifically, the fixing plate 100 is provided with a fixing groove, and the connecting nut 301 is fixedly installed in the fixing groove. Traditionally, tools are needed to fix the nut and prevent it from rotating when tightening the screw. However, by designing a fixing groove to fix the connecting nut 301, the operation of fixing the nut can be reduced during the tightening of the connecting screw 300, which greatly simplifies the operation steps and improves work efficiency.

[0039] Preferably, there are two connecting screws 300, both of which pass through the limiting part 200 and are threadedly connected to the connecting nut 301. By using two connecting screws 300, the connection strength and stability between the limiting part 200 and the fixing plate 100 can be significantly increased. Compared with a single screw, the twin-screw design can distribute stress more evenly and reduce the risk of loosening or damage to the entire structure due to the failure of a single connection point.

[0040] More preferably, it also includes a fixed bracket 400, on which a support shaft 401 is fixedly mounted. The support shaft 401 is provided with multiple linearly distributed hinge shafts 402, which are hinged to each other. The swing directions of the multiple hinge shafts 402 are not parallel, and the end hinge shaft 402 is fixedly connected to the fixed plate 100.

[0041] In this embodiment, the fixed plate 100 can be flexibly adjusted in multiple directions by means of the hinge shaft 402. When it is necessary to move the fixed plate 100 into or out of the milling machine, the angle and position of the fixed plate 100 can be easily adjusted by utilizing the swing characteristics of the hinge shaft 402, thus avoiding operational difficulties caused by space limitations.

[0042] It should be noted that each end of the hinge shaft 402 is provided with a locking handle to lock the position of the hinge shaft 402 after it swings. The hinge shaft 402 at the end extends to form two hinge sections, and the two hinge sections form a triangular structure with the fixed plate 100.
