Description

Technical Field

[0001] The present application relates to the technical field of machine tools, and in particular to a clamping mechanism for machine tools. Background Art

[0002] Machine tools are mechanical equipment used to process materials such as metal, plastic, and wood. They process raw materials through cutting, grinding, stamping, drilling, turning, etc. to produce parts or products of various shapes and sizes.

[0003] When the machine tool is processing a diamond-shaped workpiece (such as drilling), the shape of the diamond-shaped workpiece makes it susceptible to external torque. When torque is applied to the diamond-shaped workpiece during clamping, the workpiece may rotate or tilt, reducing the clamping stability and making it difficult to clamp diamond-shaped workpieces of different models. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to provide a clamping mechanism for a machine tool to solve the problems in the prior art.

[0005] To achieve the above purpose, the utility model provides a clamping mechanism for a machine tool, including a machine base, a frame welded to the outside of the machine base, a puncher slidably connected to the inside of the frame through a driving mechanism, a processing seat fixedly connected to the machine base, a V-shaped groove is provided on the top of the processing seat, a diamond-shaped workpiece is movably clamped on the V-shaped groove, and a clamping mechanism for clamping the diamond-shaped workpiece is provided on the processing seat.

[0006] Preferably, the driving mechanism includes a motor fixedly mounted on the outer surface of the frame, the output end of the motor is fixedly connected to a screw rod, and the screw rod passes through the inner side of the puncher and is threadedly engaged with the puncher. The position of the puncher can be adjusted through the driving mechanism so that holes can be opened at different positions of the diamond-shaped workpiece.

[0007] Preferably, the positioning mechanism includes a vertical shaft fixedly connected to the top of the processing seat, and the top of the vertical shaft is fixedly connected to a support platform. The positioning mechanism can stably place the diamond-shaped workpiece in the V-shaped groove of the processing seat and keep it in a stable state during the processing.

[0008] Preferably, a screw rod is threadedly sleeved on the inner surface of the support platform, and a handle is fixedly connected to the top of the screw rod.

[0009] Preferably, the bottom of the screw rod is rotatably connected to a clamping platform, and arc surfaces are provided on both sides of the clamping platform, and the outer surfaces of the arc surfaces are slidably connected to the outer surface of the vertical shaft.

[0010] Preferably, a V-shaped stepped surface is provided at the bottom of the clamping platform.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The clamping mechanism of the machine tool can firmly clamp the workpiece through the V-shaped groove and the clamping table in the clamping mechanism. The V-shaped groove and the V-shaped step surface can fit the edges and corners of the workpiece to provide a stable clamping support, avoiding the rotation or tilt of the workpiece caused by external torque, thereby improving the stability and accuracy of processing.

[0013] 2. The clamping mechanism and positioning mechanism of the machine tool have great adaptability. When processing diamond workpieces of different shapes and sizes, workers do not need to redesign or adjust the clamping method for each workpiece. Compared with the traditional clamping method, this flexibility greatly reduces the processing preparation time and adjustment cost, and improves production efficiency.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-3 A clamping mechanism for a machine tool comprises a machine base 1, a frame 2 is welded on the outer side of the machine base 1, a puncher 5 is slidably connected to the inner side of the frame 2 through a driving mechanism, a processing seat 6 is fixedly connected to the machine base 1, a V-shaped groove 7 is provided on the top of the processing seat 6, a diamond workpiece 8 is movably clamped on the V-shaped groove 7, and a clamping mechanism for clamping the diamond workpiece 8 is provided on the processing seat 6.

[0020] Through the above technical solution, the device can stably clamp the diamond-shaped workpiece 8 in the V-shaped groove 7 through the clamping mechanism when in use, and cooperate with the driving mechanism to adjust the position of the puncher 5 to only drill holes on the surface of the diamond-shaped workpiece 8.

[0021] Specifically, the driving mechanism includes a motor 3 fixedly mounted on the outer surface of the frame 2, the output end of the motor 3 is fixedly connected to a screw rod 4, and the screw rod 4 passes through the inner side of the punch 5 and is threadedly engaged therewith.

[0022] Through the above technical solution, the screw rod 4 can be linked with the punch 5 during the rotation process to make it move axially along the surface of the screw rod 4.

[0023] Specifically, the positioning mechanism includes a vertical shaft 9 fixedly connected to the top of the processing seat 6 , and a support platform 10 is fixedly connected to the top of the vertical shaft 9 .

[0024] Through the above technical solution, the vertical shaft 9 plays a role in relatively limiting the clamping platform 13, thereby preventing the clamping platform 13 from rotating synchronously with the rotation of the screw rod 11.

[0025] Specifically, a screw rod 11 is threadedly sleeved on the inner surface of the support platform 10 , and a handle 12 is fixedly connected to the top of the screw rod 11 .

[0026] Through the above technical solution, when the handle 12 is rotated to drive the screw rod 11 to rotate, the screw rod 11 will gradually move downward.

[0027] Specifically, the bottom of the screw rod 11 is rotatably connected to a clamping platform 13 , and arc surfaces 14 are provided on both sides of the clamping platform 13 , and the outer surface of the arc surface 14 is slidably connected to the outer surface of the vertical shaft 9 .

[0028] Through the above technical solution, the arc surface 14 fits with the surface of the vertical shaft 9, which can effectively prevent the rotation of the clamping platform 13.

[0029] Specifically, a V-shaped stepped surface 15 is formed at the bottom of the clamping platform 13 .

[0030] Through the above technical solution, the V-shaped stepped surface 15 is V-shaped as a whole, and a plurality of stepped terraces are arranged inside the V-shaped stepped surface 15 .

[0031] Working principle: When the device is in use, first place the diamond workpiece 8 in the V-shaped slot 7 opened on the top of the processing seat 6, then rotate the handle 12 to drive the screw 11 to rotate. During this process, the screw 11 will gradually move down, and because the arc surfaces 14 on both sides of the clamping platform 13 fit the surface of the vertical shaft 9, the vertical shaft 9 can relatively limit the clamping platform 13. The clamping platform 13 will not rotate synchronously with the screw 11, but will move downward synchronously with the screw 11 until the V-shaped stepped surface 15 at the bottom of the clamping platform 13 stably clamps the other corner of the diamond workpiece 8, so that the diamond workpiece 8 is in a stable clamping state, and finally turn on the motor 3 to drive the screw 4 to rotate, and the drilling is linked. The machine 5 moves along the axial direction of the screw rod 4, and after adjusting to a suitable position, the diamond workpiece 8 is opened. In this process, the diamond workpiece 8 is firmly clamped by using the V-shaped groove 7 and the clamping table 13, avoiding rotation or tilting of the workpiece due to external torque, thereby improving the stability and accuracy of the processing. In addition, the combination of the V-shaped groove 7 and the clamping table 13 can better adapt to diamond workpieces 8 of different shapes and sizes. The V-shaped groove 7 can fit the edges and corners of the workpiece to provide a stable clamping support, and the clamping table 13 can cooperate with the V-shaped step surface 15 to clamp and limit workpieces of different specifications.

[0032] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
