Description

Technical Field

[0001] The utility model relates to the field of clamps, and more specifically to an adjustable graphite clamp used for graphite part machine tool processing. Background Art

[0002] The main function of the graphite fixture is to fix the graphite material to be processed to ensure that the graphite material will not move or deform during the processing. This is crucial to ensure processing accuracy, especially in high-precision processing. Even a slight shift or deformation may cause the product quality to fail to meet the standard or even become waste, so the clamping stability requirement is high.

[0003] Although the existing graphite clamps can be adjusted to a certain extent, usually only one side of the clamp can be adjusted, while the other side is fixed, which limits the adaptability of the clamp to graphite parts of different specifications, and the position of the clamped workpiece is poorly adjustable. The contact surface between the clamp and the graphite part of some clamps is limited, which can also lead to unstable clamping, making the graphite part easy to move and affecting the processing of the graphite part. In addition, the adjustment of the clamp is not flexible enough, and complex tools or operations are required to achieve adjustment, which not only increases the difficulty of operation, but also reduces work efficiency.

The top ends of the first and second clamping plates have a top slide groove that cooperates with the top connecting beam 5, and the bottom ends have a bottom slide groove that cooperates with the bottom connecting beam 4. The first clamping plate 6 has a plurality of first locking bolts 6.1 that can fix the relative position of the first clamping plate 6 and the bottom plate 1, and the second clamping plate 7 has a plurality of second locking bolts 7.3 that can fix the relative position of the second clamping plate 7 and the bottom plate 1. The first screw rod 8 passes through the first end plate 2 and a first hand wheel 8.1 is installed at the end. The second screw rod 9 passes through the second threaded hole and a second hand wheel 9.1 is installed at the end.

[0027] The top and bottom ends of the first clamping plate 6 both have a first protrusion 6.2, and the first locking bolt 6.1 is installed at the first protrusion 6.2; the top and bottom ends of the second clamping plate 7 both have a second protrusion 7.4, and the second locking bolt 7.3 is installed at the second protrusion 7.4; the base plate 1 is fixedly connected with a plurality of reinforcing plates 10, and the reinforcing plates 10 have a top protrusion connected to the top cross beam and a bottom protrusion connected to the bottom cross beam; the first locking bolt 6.1 and the second locking bolt 7.3 are each four; the base plate 1 has a plurality of strip-shaped through holes 1.1.

[0028] Working principle: The positions of the two clamping plates of the graphite clamp of the present application can be adjusted, so that the graphite parts can be clamped well and the clamping is more stable, which makes it convenient to machine the graphite parts. It can also adapt well to graphite parts of different sizes and shapes, improving the flexibility and practicality of the clamp. The positions of the two clamping plates can be easily adjusted by two hand wheels, which makes the operation simple and fast, and improves work efficiency.

[0029] When in use, fix the bottom plate of the clamp on the workbench of the machine tool. After the clamp is fixed, place the graphite piece between the first clamping plate and the second clamping plate, and adjust the positions of the two clamping plates according to the size and shape of the graphite piece. Specifically, the first screw is rotated by the first hand wheel. Since the first screw is matched with the first threaded hole of the first clamping plate, the first clamping plate will move along the direction of the top connecting beam and the bottom connecting beam, thereby adjusting the position of the first clamping plate. At the same time, the second screw is rotated by the second hand wheel. Since the second screw is matched with the second bearing of the second clamping plate, and the second clamping plate has a circular through hole for the first screw to pass through, the second clamping plate will move along the direction of the top connecting beam and the bottom connecting beam, thereby adjusting the position of the second clamping plate, until the graphite piece is stably clamped by the first and second clamping plates, and then the first clamping plate and the second clamping plate are fixed respectively with the first locking bolt and the second locking bolt to ensure that the clamping plates will not move during the processing. Then install the tools required for processing and start the machine tool to process the graphite piece. During the processing, the position of the clamping plate can be adjusted in time as needed.

[0031] like Figure 3 As shown, the difference between Example 2 and Example 1 is that the first clamping plate 6 and the second clamping plate 7 are both fixedly connected with an extension plate 11. Thus, the clamping contact surface can be larger, the clamping is more stable, and the graphite part is not easy to move.

[0032] Although the present invention has been illustrated and described with respect to preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
