Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and more specifically, to a fixed fixture for a milling machine. Background Technology

[0002] During milling, the workpiece needs to be reliably fixed on the machine tool table to ensure machining accuracy and operational safety. Currently used workpiece fixing devices are typically only suitable for workpieces of specific shapes or sizes. When the workpiece changes, it often requires disassembling and reinstalling the entire fixture or making complex adjustments. This changeover process is cumbersome and time-consuming, impacting production efficiency and equipment utilization. Furthermore, the fixed position of traditional fixtures makes it difficult to flexibly adjust according to the specific dimensions of the workpiece and the location of the clamping points, thus limiting clamping options. Utility Model Content

[0003] The purpose of this utility model is to provide a fixed fixture for milling machines that can adapt to workpieces of different sizes and shapes, improve the convenience of operation, and thus improve the efficiency and flexibility of CNC machining.

[0004] A milling machine fixture, comprising:

[0005] The base has multiple parallel grooves arranged on its surface; and

[0006] Multiple fixing clamps, each of which can be slidably connected to the base via one of the sliding grooves;

[0007] The fixing fixture includes a support plate and a positioning component. The lower end of the support plate is provided with a slider that slides in cooperation with the slide groove. The positioning component is located on the upper surface of the support plate. One end of the support plate extends horizontally outward to form a support part for supporting the workpiece.

[0008] In the above technical solution, the fixture can be slidably connected to one of the parallel sliding grooves on the base surface, allowing for flexible adjustment of its position and number on the base. This adapts to the clamping requirements of workpieces of different sizes, significantly improving the fixture's compatibility and flexibility with various workpieces. The slider at the lower end of the support plate cooperates with the sliding groove to enable rapid movement and positioning of the fixture. The extended support portion provides a stable support surface for the workpiece, and the positioning component can abut against the side of the product, further enhancing positioning stability.

[0009] Furthermore, the positioning component includes a fixed block, a movable block, and an adjusting screw. The fixed block is fixedly connected to the support plate, the movable block is movably disposed on the side of the fixed block near the support portion, and the adjusting screw passes through the fixed block and abuts against the movable block.

[0010] In the above technical solution, the fixed block is fixedly connected to the bearing plate, and the adjusting screw can drive the movable block to move relative to the fixed block, thereby fine-tuning the position of the movable block to ensure that it fits the workpiece surface and improves the stability and flexibility of positioning.

[0011] Furthermore, the adjusting screw is threadedly engaged with the fixed block.

[0012] In the above technical solution, the adjusting screw and the fixed block are threaded together. By rotating the screw, the displacement of the moving block can be precisely controlled, so as to achieve fine adjustment of the clamping force and stable locking.

[0013] Furthermore, it also includes at least one guide rod, one end of which is connected to the movable block, and the other end of which is movably inserted through the fixed block.

[0014] In the above technical solution, the guide rod can connect the movable block and the fixed block, while ensuring the stability of the movable block's movement.

[0015] Furthermore, a flexible anti-slip element is attached to the surface of the movable block facing the bearing portion.

[0016] In the above technical solution, a flexible anti-slip component is added to the surface of the movable block to increase the friction with the workpiece and buffer local pressure during clamping, thereby avoiding scratching the workpiece surface.

[0017] Furthermore, the end of the adjusting screw away from the movable block is provided with a screwing part.

[0018] In the above technical solution, a screwing part is provided at the end of the adjusting screw, providing a structure that is easy to operate manually, and the clamping state can be quickly adjusted without tools.

[0019] Furthermore, it also includes a positioning pin, which is detachably connected to the support portion.

[0020] In the above technical solution, the detachable positioning pin can improve the applicability and flexibility of the fixed fixture. In specific implementation, for workpieces with positioning pin holes, positioning pins can be installed on the bearing part and the workpiece can be positioned by the positioning pins. For workpieces without positioning pin holes, the workpiece can be clamped and positioned by the positioning component. In this way, the fixed fixture can select the positioning method according to different workpiece types, making it more flexible and convenient to use.

[0021] Furthermore, the bearing portion is provided with a threaded groove, and one end of the positioning pin is provided with a threaded portion that matches the threaded groove.

[0022] In the above technical solution, the threaded groove of the bearing part cooperates with the threaded part of the positioning pin to achieve stable installation and positioning of the positioning pin, and the installation and disassembly are convenient, thus improving the efficiency of disassembly and assembly.

[0023] Compared with existing technologies, the advantages of this invention are as follows: Multiple parallel sliding grooves on the base surface allow the fixture to be slidably connected to one of these grooves, enabling flexible adjustment of the fixture's position and quantity on the base. This adapts to the clamping requirements of workpieces of different sizes, significantly improving the fixture's compatibility and flexibility with various workpieces. The slider at the lower end of the support plate, in conjunction with the sliding groove, enables rapid movement and positioning of the fixture. The extended support portion provides a stable support surface for the workpiece, and the positioning component abuts against the side of the product, further enhancing positioning stability.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] Please refer to Figures 1 to 4In a preferred embodiment, the milling machine fixture 2 of this utility model mainly includes a base 1 and multiple fixtures 2. The base 1 has multiple parallel sliding grooves 11 arranged on its surface, and each fixture 2 can be slidably connected to the base 1 via one of these grooves 11. The fixture 2 includes a support plate 21 and a positioning assembly 22. The lower end of the support plate 21 is provided with a slider 212 that slidably engages with the sliding grooves 11. The positioning assembly 22 is located on the upper surface of the support plate 21, and one end of the support plate 21 extends horizontally outward to form a support portion 211 for supporting the workpiece.

[0033] For example, the base 1 can be connected to an automated milling machine (not shown). Slides 11 are arranged at equal intervals on the base 1 and extend along its length. In this embodiment, the slides 11 are formed as T-shaped slots. A slider 212 is disposed on the lower end face of the support plate 21 and is formed as a T-shape matching the slides 11. The slider 212 can be inserted into the slides 11 from one end and slide along the slides 11. Through the multiple slides 11 arranged parallel to each other on the surface of the base 1, the fixing fixture 2 can be slidably connected to one of the slides 11, allowing the fixing fixture 2 to flexibly adjust its position and number on the base 1, thereby adapting to the clamping requirements of workpieces of different sizes and significantly improving the compatibility and flexibility of the fixture for different workpieces. The slider 212 at the lower end of the support plate 21 cooperates with the slides 11 to achieve rapid movement and positioning of the fixing fixture 2. The extended support portion 211 provides a stable support surface for the workpiece, and the positioning component 22 can abut against the side of the product, further improving the stability of the positioning.

[0034] The positioning component 22 includes a fixed block 221, a movable block 222, and an adjusting screw 223. The fixed block 221 is fixedly connected to the support plate 21. The movable block 222 is movably disposed on the side of the fixed block 221 near the support portion 211. The adjusting screw 223 passes through the fixed block 221 and abuts against the movable block 222. For example, the fixed block 221 is disposed at one end of the support plate 21 and can be fixedly connected to the support plate 21 by screws. The axial direction of the adjusting screw 223 is parallel to the extension direction of the slide groove 11, and one end of the adjusting screw passes through the fixed block 221 and abuts against the movable block 222. The adjusting screw 223 can drive the movable block 222 to move relative to the fixed block 221, thereby fine-tuning the position of the movable block 222 to ensure that it fits against the workpiece surface and improves the stability and flexibility of positioning.

[0035] In this embodiment, the adjusting screw 223 is threadedly engaged with the fixed block 221. By rotating the screw, the displacement of the movable block 222 can be precisely controlled, achieving fine-tuning of the clamping force and stable locking.

[0036] The positioning component 22 in this embodiment further includes at least one guide rod 224. One end of the guide rod 224 is connected to the movable block 222, and the other end of the guide rod 224 is movably inserted through the fixed block 221. For example, there are two guide rods 224, which are respectively disposed on both sides of the adjusting screw 223, and the axial direction of the guide rod 224 is parallel to the axial direction of the adjusting screw 223. The guide rods 224 can connect the movable block 222 and the fixed block 221, while ensuring the stability of the movement of the movable block 222.

[0037] In some possible embodiments, an elastic element such as a spring may be fitted around the outer periphery of the guide rod 224. The elastic element is compressed between the fixed block 221 and the movable block 222, thereby giving the movable block 222 a continuous elastic force toward the bearing portion 211, ensuring that the movable block 222 fits tightly with the workpiece and improving the stability of the positioning.

[0038] A flexible anti-slip element 225 is attached to the surface of the movable block 222 facing the bearing part 211. The flexible anti-slip element 225 can be made of existing flexible materials, such as rubber or silicone. By adding the flexible anti-slip element 225 to the surface of the movable block 222, the friction with the workpiece is increased and local pressure is buffered during clamping, thus avoiding scratching the surface of the workpiece.

[0039] In this embodiment, the end of the adjusting screw 223 away from the movable block 222 is provided with a screwing part 226. By providing the screwing part 226, a structure that is easy to operate manually can be provided, and the clamping state can be quickly adjusted without tools.

[0040] The fixing clamp 2 in this embodiment also includes a positioning pin 23, which is detachably connected to the support portion 211. Specifically, the support portion 211 is provided with a threaded groove 213, and one end of the positioning pin 23 is provided with a threaded portion that matches the threaded groove 213. The threaded groove 213 of the support portion 211 and the threaded portion of the positioning pin 23 cooperate to achieve a stable installation and positioning of the positioning pin 23, and the installation and disassembly are convenient, improving the efficiency of assembly and disassembly. The detachable positioning pin 23 can improve the applicability and flexibility of the fixing clamp 2. In specific implementation, for workpieces with holes for positioning pins 23, the positioning pins 23 can be installed on the support portion 211 and the workpiece can be positioned by the positioning pins 23. For workpieces without holes for positioning pins 23, the workpiece can be clamped and positioned by the positioning component 22. In this way, the fixing clamp 2 can select the positioning method according to different workpiece types, making it more flexible and convenient to use.
