DETAILED DESCRIPTION

[0028] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection.

[0029] When the machine platform pointed out in the background technology clamps the workpiece, only one processing surface can be exposed, which leads to the need to clamp multiple times on the same machine platform, resulting in cumbersome operation and low production efficiency. The utility model provides a flip clamp, which aims to push the rotating plate 3 to rotate on the support structure 2 through the fork 4, so that the workpiece clamped by the clamping component 5 can have multiple processing surfaces, thereby reducing the number of clamping times of the workpiece on the CNC machine platform and improving the processing efficiency of the workpiece.

[0030] like Figures 1 to 4 As shown, the flip clamp of the utility model includes: a base 1, a support structure 2 is formed on the base 1, and a first waist hole 21 is opened on the side of the support structure 2; a rotating plate 3, the rotating plate 3 is rotatably installed in the support structure 2, and the part of the rotating plate 3 located in the support structure 2 is formed with a crank portion 31, and a second waist hole 32 is formed on the crank portion 31; a shift fork 4, the shift fork 4 extends into the first waist hole 21 and passes through the second waist hole 32 of the rotating plate 3, and the shift fork 4 is pushed along the direction of the first waist hole 21 to rotate the rotating plate 3 relative to the support structure 2; a clamping assembly 5, the clamping assembly 5 is arranged at the end of the rotating plate 3 away from the support structure 2, and the clamping assembly 5 is used to clamp an object.

[0031] See also Figures 1 to 3 The support structure 2 formed on the base 1 is roughly "concave" shaped, and the first waist hole 21 is horizontally opened on the side of the support structure 2; the rotating plate 3 has a relative load-bearing end and a rotating end, and the rotating end is installed in the support structure 2 by rotating the shaft, and the load-bearing end extends out of the support structure 2 and installs the clamping assembly 5. The side of the rotating end of the rotating plate 3 forms a crank portion 31, and the second waist hole 32 is opened in the crank portion 31. The shift fork 4 passes through the first waist hole 21 through the second waist hole 32, so that when the shift fork 4 moves forward in the first waist hole 21, the rotating plate 3 rotates clockwise, so that the rotating plate 3 changes from a horizontal state to a vertical state. When the shift fork 4 retreats in the first waist hole 21, the rotating plate 3 rotates counterclockwise, and the rotating plate 3 changes from a vertical state to a horizontal state. By adjusting the moving distance of the shift fork 4 in the first waist hole 21, the angle of the load-bearing end of the rotating plate 3 can be adjusted, so that the workpiece clamped by the clamping assembly 5 has different processing angles, reducing the number of clamping times of the workpiece on the CNC machine, and improving the processing efficiency of the workpiece.

[0032] In other possible implementations, the crank portion 31 and the shift fork 4 at the bottom of the rotating plate 3 are omitted; in this case, an arc-shaped tooth surface structure is configured at the bottom of the rotating plate 3, and a rack is slidably installed in the support structure 2, and the rack meshes with the tooth surface structure. By controlling the rack to move forward or backward in the support structure 2, the rotating plate 3 can also be rotated clockwise or counterclockwise, and the angle of the clamping assembly 5 installed at the bearing end of the rotating plate 3 can be adjusted, so that the workpiece clamped by the clamping assembly 5 has different processing angles.

[0033] In one or more embodiments, the clamping assembly 5 includes: a shell 51, the shell 51 is a hollow structure, and at least two groups of symmetrically arranged slide grooves 52 are formed through the top surface of the shell 51, and a clamping claw 53 is slidably installed in the slide groove 52; a servo motor 54, the servo motor 54 is arranged in the shell 51, and a turntable 55 is arranged at the rotating shaft end of the servo motor 54; a connecting rod 56, the connecting rod 56 has a first end and a second end, the first end is rotatably installed on the turntable 55, and the second end is rotatably installed on the clamping claw 53.

[0034] See also Figure 4 There may be two, three, four, etc. slide grooves 52 formed through the top surface of the shell 51, and the specific number is not limited. It should be noted that several slide grooves 52 are evenly arranged on the shell 51 with the central axis of the shell 51 as the center.

[0035] When clamping the workpiece, the turntable 55 is controlled to rotate clockwise by the servo motor 54, and the turntable 55 drives the clamping jaws 53 to move toward the central axis of the shell 51 through the connecting rod 56 to clamp the workpiece; correspondingly, the turntable 55 is controlled to rotate counterclockwise by the servo motor 54 to release the clamping of the workpiece. The structure is simple and the operation is convenient. The workpiece is clamped by the clamping jaws 53 so that the surface to be processed of the workpiece is exposed, which is convenient for processing.

[0036] In one or more embodiments, the base 1 is provided with a driving device 6 for driving the shift fork 4 to move along the first waist hole 21. Figure 1 , Figure 3 The driving device 6 can be a driving cylinder, and the fork 4 is roughly in a "U" shape. The extended shaft end of the driving cylinder is connected to the fork 4. The driving cylinder drives the fork 4 to move horizontally, so that the rotating plate 3 can rotate relative to the support structure 2.

[0037] In one or more embodiments, a rubber pad is installed on the surface of the clamping jaw 53 facing the central axis of the housing 51. This arrangement can increase the friction between the workpiece and the clamping jaw 53, while reducing the wear of the workpiece by the clamping jaw 53, thereby improving the aesthetics of the workpiece processing.

[0038] In one or more embodiments, a concave structure or a convex structure is formed on the surface of the rubber pad. This arrangement can further increase the friction between the clamping jaws 53 and the workpiece, and reduce the phenomenon of displacement of the workpiece between the clamping jaws 53.

[0039] In one or more embodiments, a baffle 7 is installed at an opening of the support structure 2 on one side where the rotating plate 3 does not rotate by means of bolts.

[0040] See also Figure 1 , Figure 3 When the baffle 7 is in contact with the side of the support structure 2, the maximum rotation angle of the turntable 55 is 90°; by adjusting the bolts so that the baffle 7 is relatively far away from the support structure 2, the maximum rotation angle of the turntable 55 is greater than 90°. Through this setting, the processing range of the workpiece of this application can be further improved, and it has practicality.

[0041] In one or more embodiments, a gasket is disposed between the baffle 7 and the support structure 2. The drawings do not show the gasket, but when the baffle 7 is relatively far away from the support structure 2, the gasket is disposed between the support structure 2 and the baffle 7 to reduce the shaking of the baffle 7.

[0042] In addition, the utility model also provides a CNC machine platform, which has the flip fixture in any of the above embodiments.

[0043] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it.
