[0002] Vertical machine tools are one of the core pieces of equipment in the machining field. Their spindles are perpendicular to the worktable, and they are widely used in milling, drilling, boring, tapping, and other machining processes. Compared to traditional horizontal machine tools, vertical machine tools offer advantages such as larger operating space, easier workpiece clamping, and a wider machining range, making them particularly suitable for multi-faceted machining of complex parts. As the manufacturing industry moves towards higher precision and efficiency, vertical machine tools are increasingly used in mold making, aerospace, automotive, and electronics industries. However, the machining accuracy and efficiency of vertical machine tools are highly dependent on the performance of the tooling fixtures. Traditional fixtures are typically designed for specific workpieces, lacking versatility and struggling to adapt to workpieces of different sizes, shapes, and materials. This necessitates frequent fixture changes or manual workpiece position adjustments during machining, severely impacting production efficiency and machining quality. Furthermore, the difficulty in adjusting the clamping force of traditional fixtures can easily cause workpiece damage or machining errors, further limiting the practical application of vertical machine tools. Summary of the Invention

[0003] To address the problem that traditional fixtures in the prior art are usually designed for specific workpieces, have poor versatility, and are difficult to adapt to workpieces of different sizes and shapes, this utility model provides an adjustable vertical machine tool machining fixture.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to Figures 1-3:

[0017] This utility model discloses an adjustable vertical machine tool machining fixture, as shown in Figure 1. The adjustable vertical machine tool machining fixture includes an operating platform 2 installed in the vertical machine tool; the vertical machine tool includes a base 1; a vertical lathe body 11 is mounted on the top of the base 1; a feed device 13 is mounted on the front side wall of the vertical lathe body 11; a lifting platform 12 is mounted on the top of the base 1; the operating platform 2 is mounted on the top of the lifting platform 12. The operating platform 2 is characterized by having an adaptive clamping component 4 that can be adaptively adjusted according to the size of the workpiece, and a positioning clamping component 3, which enables machining... Multi-point clamping of the workpiece; in this embodiment, the adaptive clamping component 4 and the positioning clamping component 3 are integrated on the operating platform of the vertical machine tool to achieve effective clamping of the workpiece; the adaptive clamping component 4 and the positioning clamping component 3 work together to ensure the stability of the workpiece during the processing by performing multi-point clamping, thereby improving the processing accuracy; first, the workpiece is placed on the operating platform 2, and then the height of the operating platform 2 is adjusted by the lifting platform 12 according to the approximate size of the workpiece so that the workpiece is in a suitable processing position; then, the adaptive clamping component 4 and the positioning clamping component 3 begin to clamp the workpiece.

[0018] As shown in Figures 1-3, the positioning and clamping assembly 3 is installed on the front side wall of the operating platform 2, including a rotating seat 31, a screw 32, a clamping head 33, and a rotating handle 34. The rotating seat 31 is welded to the front side wall of the operating platform 2. A threaded hole is opened inside the rotating seat 31, and the screw 32 is threadedly connected to the inside of the threaded hole. One end of the screw 32 is rotatably connected to the clamping head 33. The other end of the screw 32 is bolted to the rotating handle 34. In this embodiment, the positioning and clamping assembly 3 utilizes the principle of threaded transmission. The threaded hole on the rotating seat 31 cooperates with the screw 32. When the screw 32 is rotated, due to the action of the thread, the screw 32 will move linearly along the threaded hole. Because one end of the screw 32 is rotatably connected to the clamping head 33, the linear movement of the screw 32 will drive the clamping head 33 to move, thereby realizing the clamping or releasing operation of the workpiece. The rotating handle 34 is for the convenience of the operator to apply torque to rotate the screw 32.

[0019] As shown in Figures 1-3, the adaptive clamping assembly 4 includes two sets of adaptive clamps 40, which are rotatably connected to the rear ends of the top of the operating platform and are used in conjunction with the positioning clamping assembly 3. A spring 44 is detachably connected between the two adaptive clamps 40. In this embodiment, the adaptive clamping assembly 4 mainly relies on the elasticity of the spring 44 and the rotation structure of the adaptive clamps 40 to achieve adaptive adjustment for workpieces of different sizes. The two sets of adaptive clamps 40 are respectively installed at the rear ends of the top of the operating platform 2 and connected by the spring 44. When the workpiece is placed on the operating platform 2, the workpiece will exert a squeezing effect on the clamping arms of the adaptive clamps 40, causing the adaptive clamps 40 to rotate around the rotating shaft sleeve 5, while stretching the spring 44. The two adaptive clamps 40 will respectively fit against the outer side wall of the workpiece, and cooperate with the positioning clamping assembly 3 to achieve positioning and clamping of the workpiece. The adaptive clamping assembly 4 can automatically adapt to workpieces of different sizes without frequent manual adjustments, which greatly improves clamping efficiency. Moreover, the adaptive clamps 40 are used in conjunction with the positioning clamping assembly 3 to clamp the workpiece from multiple directions, further improving the stability of the workpiece.

[0020] As shown in Figures 1-3, the adaptive clamp 40 includes a first clamping arm 41, a second clamping arm 42, a connecting part 43, and a connecting rod 431. The first clamping arm 41, the second clamping arm 42, and the connecting part 43 are integrally formed. The clamping angle between the first clamping arm 41 and the second clamping arm 42 is set to 60°-90°. The connecting part 43 is internally connected to the connecting rod 431 by bolts. A spring 44 is hung between the two connecting rods 431. In this embodiment, the first clamping arm 41, the second clamping arm 42, and the connecting part 43 of the adaptive clamp 40 are integrally formed, ensuring the stability and strength of the structure. The clamping angle between the first clamping arm 41 and the second clamping arm 42 is set to 60°-90°, and this angle design allows the clamping arms to better... The adaptive clamp 40 conforms to the edges of workpieces of different shapes, improving the clamping effect. The connecting rod 431 is used to connect the spring 44, and the spring 44 transmits the elastic force to the adaptive clamp 40 through the connecting rod 431, thereby achieving the clamping of the workpiece. In use, the workpiece is placed on the operating platform 2. When the workpiece contacts the clamping arm of the adaptive clamp 40, it will push the clamping arm to rotate outward or inward. The rotation of the clamping arm will cause the adaptive clamp 40 to rotate around the rotating shaft sleeve 5. At the same time, the spring 44 connecting the two adaptive clamps 40 will be stretched. The elastic force generated by the spring 44 will cause the clamping arm to press tightly against the edge of the workpiece. As the size of the workpiece is different, the rotation angle of the clamping arm and the deformation degree of the spring 44 will also change accordingly to achieve the effect of adaptive clamping.

[0021] As shown in Figures 1-3, a corresponding rotating sleeve 5 is welded to the top of the operating platform 2 relative to the position of the adaptive clamp 40. The adaptive clamp 40 is rotatably connected inside the rotating sleeve 5 and is installed in this embodiment by fixing bolts 51. The rotating sleeve 5 welded to the top of the operating platform 2 provides a support point for the rotation of the adaptive clamp 40. The adaptive clamp 40 is installed inside the rotating sleeve 5 by fixing bolts 51. The fixing bolts 51 can ensure that the adaptive clamp 40 can rotate freely around the rotating sleeve 5 and prevent the adaptive clamp 40 from coming out of the rotating sleeve 5 during operation.

[0022] The implementation principle of this utility model embodiment is as follows:

[0023] As shown in Figure 3, taking the clamping of a square workpiece as an example, the square workpiece is first placed on the operating platform 2. The two apex corners of the square workpiece are respectively inserted between the first clamping arm 41 and the second clamping arm 42 of the adaptive clamp 40. When the two clamping arms completely press against the edge of the square workpiece, the spring 44 is in a stretched state. At this time, grasp the rotating handle 34 and rotate the screw 32 so that the clamping head 33 presses against the front side wall of the workpiece, so that the two adaptive clamps 40 completely limit and clamp the square workpiece.
