Abstract
Description
Technical Field
[0001] The utility model relates to the field of cylindrical ceramic fixtures, in particular to a special deep-hole cylindrical fixture for grinding new energy ceramic materials. Background Art
[0002] The development of new energy technologies has necessitated grinding of specialized deep-hole cylindrical workpieces. However, due to the unique characteristics of ceramics, a new energy material, ceramics offer high hardness and excellent insulation properties, but their high hardness also comes with an extremely brittle structure. Even slightly forceful clamping of the cylindrical outer ring in the chuck can easily lead to cracks. Therefore, the outer ring of cylindrical workpieces cannot be directly clamped, requiring specialized tooling to meet these grinding requirements. Utility Model Content
[0003] The embodiment of the present application solves the technical problem in the existing technical solution that the cylindrical ceramic workpiece has high hardness and extremely brittle structure, which easily causes the cylindrical ceramic workpiece to become brittle or crack when the chuck is used to clamp its cylindrical outer ring with a little force, by providing a special deep-hole collet tool for grinding new energy ceramic materials.
[0004] The technical solutions adopted in the embodiments of this application are as follows:
[0005] A special deep-hole collet tool for grinding new energy ceramic materials, comprising a cylindrical seamless steel pipe for supporting a workpiece, a center frame for supporting the cylindrical seamless steel pipe, a chuck for tightening the cylindrical seamless steel pipe, and a positioning mechanism for positioning the workpiece; a plurality of groups of the positioning mechanisms arranged in a circular array are installed at both ends of the cylindrical seamless steel pipe; the center frame is clamped at the middle section of the outer side of the cylindrical seamless steel pipe; and the chuck is clamped at the outer end of the cylindrical seamless steel pipe.
[0006] A further technical solution is: the positioning mechanism includes a mounting block, a first screw for fixing the mounting block, a pin for abutting against a workpiece, a support rod for driving the pin to move, a support screw for driving the support rod to move, a handle for driving the support screw to rotate, a positioning pin for fixing the handle, a pressure cover embedded in the mounting block, a second screw for fixing the pressure cover, and a third screw for limiting the support rod; the mounting block is fixedly mounted on the outside of the cylindrical seamless steel pipe by two groups of the first screws; the pin is arranged at the end of the support rod; the handle is fixedly mounted on the support screw by the positioning pin; the support rod is threadedly connected to the support screw; the support screw is rotatably connected to the pressure cover; the pressure cover is fixedly mounted on the mounting block by the second screw; the third screw is threadedly connected to the mounting block, and the third screw is clamped in the support rod groove to limit the support rod from rotating.
[0007] The material of the plug is bakelite.
[0008] Three groups of positioning mechanisms arranged in a circular array are installed at both ends of the cylindrical seamless steel pipe.
[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0010] 1. Due to the use of the cylindrical seamless steel pipe, center frame, chuck and positioning mechanism, by inserting the cylindrical workpiece into the inner side of the cylindrical seamless steel pipe, and then supporting the workpiece in turn through the six groups of positioning mechanisms installed on the outer ring of the cylindrical seamless steel pipe, the workpiece placed on the inner side of the cylindrical seamless steel pipe can be positioned. Then the outer ring end side of the cylindrical seamless steel pipe is directly clamped by the chuck, and the middle section of the cylindrical seamless steel pipe is clamped by the center frame. At this time, the center frame plays an auxiliary supporting role for the cylindrical seamless steel pipe, and then the inner side of the cylindrical workpiece can be ground by the grinding rod. When the staff positions the cylindrical workpiece through the positioning mechanism, the staff drives the support screw to rotate together by turning the handle. Since the support rod is threadedly connected to the support screw, and the third screw is clamped in the support rod groove to limit the support rod from rotating, when the support screw rotates, the support rod can drive the head to move closer to or away from the workpiece. By simultaneously placing the plugs in each positioning mechanism against the outer surface of the workpiece, the workpiece can be effectively positioned, thus avoiding direct clamping of the outer ring of a cylindrical ceramic workpiece made of brittle material, which could prevent brittle cracking. The combined clamping of the chuck and center rest provides a more secure grip on the cylindrical seamless steel pipe. By employing six sets of retractable positioning mechanisms, cylindrical workpieces of varying diameters can be secured. Furthermore, extra-long cylindrical seamless steel pipes can be used to clamp workpieces of exceptional length, thus addressing process versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The embodiment of the present application solves the technical problem in the existing technical solution that the cylindrical ceramic workpiece has high hardness and extremely brittle structure, which easily causes the cylindrical ceramic workpiece to become brittle or crack when the chuck is used to clamp its cylindrical outer ring with a little force, by providing a special deep-hole collet tool for grinding new energy ceramic materials.
[0015] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:
[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0017] A special deep hole collet tool for grinding new energy ceramic materials, such as Figure 1 and Figure 2 As shown, the apparatus comprises a cylindrical seamless steel tube 1 for supporting a workpiece, a center frame 2 for supporting the tube 1, a chuck 3 for tightening the tube 1, and a positioning mechanism 4 for positioning the workpiece. Several sets of positioning mechanisms 4 are mounted in a circular array at each end of the tube 1. The center frame 2 is clamped to the outer middle section of the tube 1. The chuck 3 is clamped to the outer end of the tube 1.
[0018] The positioning mechanism 4 includes a mounting block 41, a first screw 42 for securing the mounting block 41, a plug 43 for abutting against a workpiece, a support rod 44 for moving the plug 43, a support screw 45 for moving the support rod 44, a handle 46 for rotating the support screw 45, a positioning pin 47 for securing the handle 46, a pressure cap 48 embedded in the mounting block 41, a second screw 49 for securing the pressure cap 48, and a third screw 50 for limiting the position of the support rod 44. The mounting block 41 is fixedly mounted on the outside of the cylindrical seamless steel pipe 1 by two sets of first screws 42. The plug 43 is disposed at the end of the support rod 44. The handle 46 is fixedly mounted to the support screw 45 by a positioning pin 47. The support rod 44 is threadedly connected to the support screw 45. The support screw 45 is rotatably connected to the pressure cap 48. The pressure cap 48 is fixedly mounted to the mounting block 41 by a second screw 49. The third screw 50 is threadedly connected to the mounting block 41 , and the third screw 50 is clamped in the groove of the support rod 44 to limit the rotation of the support rod 44 .
[0019] Three sets of positioning mechanisms 4 are fixedly mounted on both ends of the cylindrical seamless steel tube 1, arranged in a circular array. A mounting block 41 is removably secured to the outside of the cylindrical seamless steel tube 1 using two sets of first screws 42. A plug 43 is fixedly connected to one end of a support rod 44. A handle 46 is removably secured to a support screw 45 using a locating pin 47. A gland 48 is removably secured to the top of the mounting block 41 using a second screw 49. The plug 43 is made of bakelite and has an arc-shaped shape.
[0020] Due to the arrangement of the cylindrical seamless steel pipe 1, the center frame 2, the chuck 3 and the positioning mechanism 4, the workpiece placed inside the cylindrical seamless steel pipe 1 is inserted, and then the workpiece is supported in sequence by the six groups of positioning mechanisms 4 installed on the outer ring of the cylindrical seamless steel pipe 1. At this time, the workpiece placed inside the cylindrical seamless steel pipe 1 can be positioned. Then, the outer ring end side of the cylindrical seamless steel pipe 1 is directly clamped by the chuck 3, and the middle section of the cylindrical seamless steel pipe 1 is clamped by the center frame. At this time, the center frame plays an auxiliary supporting role for the cylindrical seamless steel pipe 1. Then, the inner side of the cylindrical workpiece can be ground by the grinding rod. When the staff positions the cylindrical workpiece through the positioning mechanism 4, the staff drives the support screw 45 to rotate together by turning the handle 46. Since the support rod 44 is threadedly connected to the support screw 45, and the third screw 50 is clamped in the groove of the support rod 44 to limit the rotation of the support rod 44, when the support screw 45 rotates, the support rod 44 can drive the head 43 to move closer to or away from the workpiece. By simultaneously placing the plugs 43 in each set of positioning mechanisms 4 against the outer surface of the workpiece, the workpiece can be effectively positioned, thereby avoiding direct clamping of the outer ring of the cylindrical ceramic brittle material workpiece and preventing brittle cracking of the workpiece. By using the chuck 3 and the center frame 4 to clamp together, the cylindrical seamless steel pipe 1 is clamped more securely. By using six sets of positioning mechanisms 4 to retract, cylindrical workpieces of different diameters can be fixed. At the same time, extra-long cylindrical seamless steel pipes 1 can be used to clamp workpieces of extremely long lengths, thereby meeting the diversity of processes.
