In the figure: 1. a screw; 2. a nut; 3. a workpiece to be processed; 4. a card slot; 5. an inner table-board; 6. a clearance groove; 7. machining a hole; 8. a three-jaw chuck.
Detailed Description
The present invention will be further explained below.
Example 1: referring to fig. 1 to 4, a clamp for processing the inner diameter of a graphite ring comprises a screw rod 1, a nut 2 and a workpiece 3 to be processed, wherein the front end of the screw rod 1 is in threaded connection with the nut 2, a clamping groove 4 matched with the shape of the workpiece 3 to be processed is formed in the end surface of the front end of the screw rod 1, the workpiece 3 to be processed is clamped and fixed in the clamping groove 4 through the nut 2 and the screw rod 1, a processing hole 7 convenient for a cutter to advance and retreat is formed in the center of the screw rod 1 and the nut 2, a table surface 5 in the clamping groove 4 and an inner table surface 5 of the nut 2 are both flat smooth surfaces, a clearance groove 6 is reserved at the root parts of the clamping groove 4 and the nut 2, in order to meet the requirement of parallelism of two end surfaces of a product and meet the requirement of verticality of the inner diameter of the end surface, the front end of the screw rod 1 and the nut 2 are processed firstly, and the inner table surfaces 5 in the clamping groove 4 and the nut 2 are both flat, the clamping groove 4 and the root part of the nut 2 are provided with a clearance groove 6 which can mainly accommodate the cutter to retreat under the state of no cutting force, so that the processing of the screw rod 1 and the inner table surface 5 of the nut 2 is convenient.
The aperture of the processing hole 7 is larger than the processing inner diameter of the workpiece 3 to be processed, the difference of the inner diameters is 1mm, and the processing hole is suitable for fine processing of the inner diameter of the graphite ring.
The inner wall of the clamping groove 4 is the same as the outer diameter of the workpiece 3 to be processed, but the depth of the clamping groove 4 is smaller than the thickness of the workpiece 3 to be processed, the workpiece 3 to be processed slightly protrudes out of the end face of the screw rod 1 after being installed, and the protruding part can enable the workpiece 3 to be processed to be clamped between the screw rod 1 and the screw cap 2 after the screw cap 2 is installed. If the graphite ring is thin, less graphite ring will be exposed, and if the graphite ring is thick, more graphite ring will be exposed.
The clamping groove 4 and the processing hole 7 are located on the same central axis, so that a uniform axis line is guaranteed, and the processing accuracy of the inner diameter of the graphite ring is guaranteed.
When in work: through the fine processing of the table-board 5 in the processing hole 7 and the clamping groove 4, the parallelism requirement after the workpiece 3 to be processed is clamped is ensured, the end face has the verticality requirement on the inner diameter, the workpiece is loaded into the clamping groove 4 of the clamp after the parallelism of the two end faces of the workpiece is ensured, and the inner diameter processing is carried out after the nut 2 is used for pressing.
