Abstract
The utility model discloses a special-shaped cylinder inner circle machining clamp, which belongs to the field of microwave technology and precision machining, and comprises a sample sleeve and a rear cover detachably connected with one end of the sample sleeve, wherein the sample sleeve is shaped like a cylinder, a through groove is formed in the sample sleeve, the outline and the size of the through groove are consistent with the outline of the periphery of a special-shaped cylinder to be machined, the depth of the through groove is consistent with the height of the special-shaped cylinder to be machined, and the center of the sample sleeve is coincident with the circle center of the inner circle of the special-shaped cylinder to be machined; after the sample sleeve is used for processing the polygonal cylinder and the special-shaped cylinder, the claw disc does not need to be frequently replaced, the sample can be processed only by replacing the sample sleeve corresponding to the cylinder, and after the sample sleeve is used, the sample does not need to be reserved for clamping positions, so that material waste is reduced, and the difficulty in manufacturing or appearance processing of a front-end forming die is reduced.
Description
Technical Field
The utility model relates to a microwave technique and precision finishing field especially relate to a circle adds clamping apparatus in abnormal shape cylinder.
Background
At present, when the inner circle of a cylinder is processed by an internal grinder based on single microwave, the claw disc can only fix a cylinder and regular polygonal cylinders, and the claw disc is difficult to fix for special polygonal cylinders and special-shaped cylinders; when the types of the special-shaped samples are various, the proper claw discs need to be frequently replaced, so that the processing efficiency is low, and when the claw discs are used for clamping workpieces, some fragile places are easy to be crushed, so that the product yield is low; if the method of reserving the clamping position is adopted, more waste is caused in the processing process.
Disclosure of Invention
An object of the utility model is to provide an circle adds clamping apparatus in heterotypic cylinder to solve above-mentioned problem.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a circle adds clamping apparatus in heterotypic cylinder, including the sample cover with the back lid of connection can be dismantled to sample cover one end, sample cover appearance is the cylinder, set up logical groove in the sample cover, the profile and the size that lead to the groove are unanimous with the heterotypic cylinder periphery profile of waiting to process, the degree of depth that leads to the groove is unanimous with the heterotypic cylinder height of waiting to process, the center of sample cover with wait to process the coincidence of the circle centre of a circle in the heterotypic cylinder.
As a preferred technical scheme: the sample sleeve is in threaded connection with the rear cover.
In order to solve the problem that the method application scope of claw dish among the prior art is little, raw materials utilization is low, need frequently change special claw dish when the sample kind is many, this application uses the sample cover to solve this problem: the sample shape is taken as a template, a special cylinder is formed, one end of the cylinder is provided with a groove, the groove depth is consistent with the length of the sample, the section of the groove is a polygon or a special shape with an inner circle containing an outer circle, the circle center of the outer circle is coincident with the circle center of the inner circle to be processed by the sample, and the bottom surface of the groove is provided with a hole for pushing out the sample. Therefore, the sample sleeve can be sleeved outside the special polygonal column body and the special-shaped column body, the sample sleeve is fixed by the claw disc, the sample sleeve and the sample can rotate together by the rotation of the claw disc, and the workpiece can be drilled and processed into an inner circle.
After the sample sleeve is used for processing the polygonal column body and the special-shaped column body, the claw disc does not need to be frequently replaced, and the sample can be processed only by replacing the sample sleeve corresponding to the column body, because the claw disc is not in direct contact with the sample, the sample cannot be damaged by the claw disc due to the fact that some parts of the sample are too fragile; after the sample sleeve is used, the clamping position of the sample does not need to be reserved, the material waste is reduced, and the difficulty in manufacturing or shape processing of a front-end forming die is reduced.
Compared with the prior art, the utility model has the advantages of: after the sample sleeve is used for processing the polygonal cylinder and the special-shaped cylinder, the claw disc does not need to be frequently replaced, the sample can be processed only by replacing the sample sleeve corresponding to the cylinder, and after the sample sleeve is used, the sample does not need to be reserved for clamping positions, so that material waste is reduced, and the difficulty in manufacturing or appearance processing of a front-end forming die is reduced.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: 1. a sample sleeve; 2. a rear cover; 3. a through groove; 4. the claw disk is fixed in position.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example (b):
referring to fig. 1, the clamp for processing the inner circle of the special-shaped cylinder comprises a sample sleeve 1 and a rear cover 2, wherein one end of the sample sleeve 1 is connected with the rear cover 2 through threads, in the embodiment, the sample sleeve 1 is cylindrical, a through groove 3 is formed in the sample sleeve, the outline and the size of the through groove 3 are consistent with the outline of the periphery of the special-shaped cylinder to be processed, the depth of the through groove 3 is consistent with the height of the special-shaped cylinder to be processed, so that the special-shaped cylinder to be processed can be just embedded into the through groove 3, and the center of the sample sleeve is superposed with the center of the inner circle of the special-shaped cylinder to be processed, so that the inner circle can be accurately processed;
taking the triangular column processing fixture of the embodiment as an example, the using method is as follows:
1. selecting a proper clamp (namely the sample sleeve 1) according to the size of a sample, mounting the clamp on an internal grinding machine, and adjusting the limit distance of a grinding head to prevent cutter collision;
2. taking down the clamp, putting the sample into the clamp, and screwing the rear cover 2;
3. fixing the clamp at a debugging position on a three-jaw disc of the internal grinding machine through a jaw disc fixing position 4, and starting machining;
4. and opening the rear cover 2 after the processing is finished, and taking out the sample to obtain the product.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
Claims (2)
1. The utility model provides a circle adds clamping apparatus in abnormal shape cylinder which characterized in that: the sample sleeve is a cylinder, a through groove is formed in the sample sleeve, the outline and the size of the through groove are consistent with the peripheral outline of the special-shaped cylinder to be processed, the depth of the through groove is consistent with the height of the special-shaped cylinder to be processed, and the center of the sample sleeve coincides with the circle center of the inner circle of the special-shaped cylinder to be processed.
2. The clamp for processing the inner circle of the special-shaped cylinder according to claim 1, wherein: the sample sleeve is in threaded connection with the rear cover.
