Description

Technical Field

[0001] This application relates to the technical field of sleeve processing, and particularly relates to a positioning device for sleeve processing. Background Art

[0002] A sleeve is a metal part made of metal processing, and its cross-section is annular. Sleeves are widely used in various mechanical equipment. After the sleeve is processed and formed, in order to ensure the smoothness of its outer surface, a polishing machine is used to polish its outer surface. Currently, when using a polishing machine to polish the outer surface of the sleeve, the sleeve needs to be positioned, so a positioning device needs to be used. The existing positioning devices generally use two clamping blocks to clamp and position the outer surface of the sleeve. This positioning method will block some areas of the outer surface of the sleeve. After polishing other areas of the outer surface of the sleeve, the position of the sleeve needs to be adjusted and repositioned, which is rather troublesome. Content of the Utility Model

DETAILED DESCRIPTION

[0014] The following is combined with Figures 1-3 This application is described in further detail.

[0015] The present application embodiment discloses a positioning device for sleeve processing, referring to Figures 1-3, including a base 1, a first conical block 21, an internally threaded fixed cylinder 22 and a second conical block 23. The first conical block 21 is welded to the middle part of the top of the base 1. The base 1 can support the first conical block 21. The internally threaded fixed cylinder 22 is fixedly installed on the top of the first conical block 21 through a connecting piece 3. The connecting piece 3 is composed of a connecting block 31 and four first bolts 32. The connecting block 31 is welded to the bottom end of the internally threaded fixed cylinder 22. Four circular holes are opened on the top of the connecting block 31. The spacing between the four circular holes is the same. The four first bolts 32 are respectively movable through the four circular holes. The four first bolts 32 are all threadedly connected to the first conical block 21, so that the internally threaded fixed cylinder 22 is vertically fixedly installed on the top of the first conical block 21. The internally threaded fixed cylinder The outer movable sleeve of 22 is provided with a sleeve body 4, and the second conical block 23 is movably sleeved on the outer surface of the top end of the internal threaded fixed cylinder 22. The two ends of the sleeve body 4 respectively conflict with the outer surface of the first conical block 21 and the outer surface of the second conical block 23. The internal thread of the internal threaded fixed cylinder 22 is inserted with a threaded rod 24, and the top of the threaded rod 24 is welded with a rotating part 25. When the rotating rotating part 25 drives the threaded rod 24 to rotate, the threaded rod 24 drives the rotating part 25 to descend synchronously, and the rotating part 25 pressurizes the second conical block 23, and the second conical block 23 pressurizes the sleeve body 4, thereby cooperating with the first conical block 21 to clamp and fix the sleeve body 4, so as to achieve the purpose of positioning the sleeve body 4, and then the outer surface of the sleeve body 4 will not move when being polished by an external polishing machine.

[0016] Reference Figure 2 and Figure 3 The rotating member 25 is composed of a hexagonal rotating block 251 and a toggle rod 252. The hexagonal rotating block 251 is welded to the top of the threaded rod 24. The hexagonal rotating block 251 can be rotated by an external wrench and tightly contact the second conical block 23. There are six toggle rods 252, which are respectively welded to the edges of the six bottom ends of the hexagonal rotating block 251. By toggling the six toggle rods 252, the hexagonal rotating block 251 can be quickly rotated to contact the second conical block 23. Then, the hexagonal rotating block 251 can be rotated by an external wrench and tightly contact the second conical block 23.

[0017] Reference Figure 1 , Figure 2 and Figure 3 A through hole is provided at the top of the base 1, and the spacing between the four through holes is the same. Second bolts 5 are movably penetrated inside the four through holes. The four second bolts 5 can be threadedly connected with the peripheral workbench by rotating, so that the base 1 can be fixedly installed on the table top of the peripheral workbench to prevent it from moving.

[0018] The implementation principle of the positioning device for sleeve processing in the embodiment of the present application is as follows: when in use, the sleeve body 4 is sleeved on the outside of the internal thread fixing cylinder 22, and the bottom end of the sleeve body 4 is made to collide with the outer surface of the first conical block 21, and then the second conical block 23 is sleeved on the outside of the internal thread fixing cylinder 22 and collide with the top end of the sleeve body 4, and then the six toggle rods 252 are toggled to quickly rotate the hexagonal rotating block 251, so that the threaded rod 24 is threadedly inserted into the internal thread fixing cylinder 22. Inside, the hexagonal rotating block 251 is brought into contact with the second conical block 23 at the same time, and then the hexagonal rotating block 251 can be turned by an external wrench to rotate and tightly contact with the second conical block 23, the hexagonal rotating block 251 pressurizes the second conical block 23, and the second conical block 23 pressurizes the sleeve body 4, thereby cooperating with the first conical block 21 to clamp and fix the sleeve body 4, thereby achieving the purpose of positioning the sleeve body 4, and then the external polishing machine can be used to grind and polish the outer surface of the sleeve body 4.
