Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for CNC lathe machining. Background Technology

[0002] According to patent authorization announcement number CN221516998U, a workpiece clamping device for CNC lathe machining is disclosed. This utility model relates to the field of clamping device technology. Its key technical points are: it includes a base, a guide rail fixedly connected to the top inner wall of the base, two sliders symmetrically slidably connected to the outer wall of the guide rail, a moving plate fixedly connected to the top outer wall of the two sliders, two driving blocks fixedly connected to the bottom outer wall of the two moving plates, and a clamp for holding the workpiece detachably installed on the opposite outer wall of the two driving blocks by bolts. A synchronization mechanism for maintaining the relative synchronous movement of the two clamps is installed on the inner wall of the base. In this utility model, by setting two cylinders, the two driving blocks can drive the two moving plates and sliders to slide relative to each other on the outer wall of the guide rail, thereby causing the two clamps to move relative to each other to clamp the workpiece. Through the cooperation of the synchronization mechanism, the moving speed of the two clamps is kept synchronous, ensuring clamping accuracy.

[0003] However, there are problems with the existing technology: as the core component of the clamping device, the flexibility of the surface fixtures of the drive block directly affects the production efficiency and equipment utilization. The fixtures on the surface of the drive block adopt a fixed structure and are permanently fixed to the surface of the drive block by welding or high-strength bolts, forming an integrated structure that cannot be disassembled. This design means that when faced with diverse workpiece types, operators cannot change the appropriate fixtures according to actual needs, making the entire clamping device only able to perform clamping operations on a single model and specification of workpiece.

The fixtures on the surface of the drive block adopt a fixed structure, which is permanently fixed to the surface of the drive block by welding or high-strength bolts, forming an integrated structure that cannot be disassembled. This design means that when facing diverse workpiece types, operators cannot change the appropriate fixtures according to actual needs, making the entire clamping device only able to perform clamping operations on a single model and specification of workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC lathe machining clamping device, comprising a CNC lathe clamping transmission base, wherein a movable plate is fixedly connected to the output end of the CNC lathe clamping transmission base, and there are two movable plates.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A CNC lathe machining clamping device includes a CNC lathe clamping transmission base 1. A movable plate 2 is fixedly connected to the output end of the CNC lathe clamping transmission base 1. There are two movable plates 2. A mounting plate 3 is provided on the top of the movable plate 2. A clamping member 4 is fixedly connected to the surface of the mounting plate 3. Fixed posts 5 are fixedly connected to the four corners of the top of the movable plate 2. A rotation limit block 6 is provided inside the fixed post 5. The top of the rotation limit block 6 extends to the top of the fixed post 5. A pushing member 7 is fixedly connected to the top of the rotation limit block 6.

[0022] Please see Figure 1-4 A hemispherical block 8 is fixedly connected to the top of the pusher 7, and the hemispherical block 8 is located on the top of the moving plate 2.

[0023] Furthermore, the hemispherical block 8 can guide the linkage plate 9, preventing the linkage plate 9 from being difficult to insert onto the surface of the pusher 7, thus improving the insertion efficiency of the linkage plate 9.

[0024] Please see Figure 1-4 The surface of the pusher 7 is fitted with a linkage plate 9, which is located at the four corners of the top of the CNC lathe clamping transmission base 1.

[0025] Furthermore, by setting the linkage plate 9, the rotation limit blocks 6 on both sides can be rotated simultaneously, avoiding the need for each rotation limit block 6 to be rotated individually, thus improving the effectiveness of the rotation limit blocks 6.

[0026] Please see Figure 1-4 A push rod 10 is fixedly connected to the top of the linkage plate 9. The push rod 10 is circular in shape.

[0027] Furthermore, by setting the push rod 10, the contact area between the user and the linkage plate 9 can be increased, avoiding a small contact area between the linkage plate 9 and the user, and improving the pushing efficiency of the linkage plate 9.

[0028] Please see Figure 1-4 The surface of the push rod 10 is fitted with a handle sleeve 11, which is located on the top of the linkage plate 9.

[0029] Furthermore, the handle sleeve 11 isolates the push rod 10 from contact with the user, preventing friction between the push rod 10 and the palm, thus improving the comfort of using the push rod 10.

[0030] Please see Figure 1-4 The top of the push rod 10 is fixedly connected to the limiting piece 12, and the handle sleeve 11 is located at the bottom of the limiting piece 12.

[0031] Furthermore, by setting the limiting piece 12, the handle sleeve 11 can be limited, preventing the handle sleeve 11 from moving upward during use, preventing the handle sleeve 11 from separating from the push rod 10, and improving the use effect of the push rod 10.

[0032] Please see Figure 1-4 A lifting bracket 13 is fixedly connected to the top of the mounting plate 3. The lifting bracket 13 is located on both sides of the top of the CNC lathe clamping transmission base 1.

[0033] Furthermore, the lifting bracket 13 facilitates the user's movement of the mounting plate 3, preventing the mounting plate 3 from being difficult to hold during movement and thus improving the efficiency of its operation.

[0034] The specific implementation process of this utility model is as follows: When processing parts, the corresponding clamping member 4 is rotated according to the model of the part. After the clamping member 4 is selected, the mounting plate 3 at the bottom of the clamping member 4 is placed on the surface of the fixed column 5. Then, the disassembled linkage plate 9 is placed on the pusher 7 and rotated to push the linkage plate 9 to rotate. The linkage plate 9 drives the pusher 7 to rotate 180 degrees. The pusher 7 drives the rotation limit block 6 to twist 180 degrees. The protruding part of the rotation limit block 6 moves out from the inside of the fixed column 5. The surface of the rotation limit block 6 is aligned with the surface of the mounting plate 3. The mounting plate 3 is fixed and limited. The mounting plate 3 and the clamping member 4 are fixed. The CNC lathe clamping transmission base 1 is started. The CNC lathe clamping transmission base 1 drives the moving plate 2, the mounting plate 3 and the clamping member 4 to move inward to clamp the workpiece.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
