Description

TECHNICAL FIELD

[0001] The utility model relates to the technical fields of fixing different specifications of parts, in particular to an auxiliary tool for processing multi-specification cylindrical parts. BACKGROUND

[0002] A certain cylindrical part 1 is a hollow cylinder, and its structure is shown in Figures 1-2 When a batch of cylindrical parts 1 of different specifications are produced in the workshop, the process requires polishing the outer cylindrical surface of the right end of the cylindrical part 1 of different specifications to process the required finished cylindrical part. Before polishing the outer cylindrical surface of the right end of the cylindrical part 1, a tooling fixture as shown in Figures 3-5 is used to fix the cylindrical part 1. The tooling fixture includes a base 2, a rotating shaft 3 installed in the base 2, a disc A 4 fixed to the right end of the rotating shaft 3, a threaded rod A 5 fixed to the right end surface of the disc A 4, and the threaded rod A 5, the disc A 4, and the threaded rod A 5 are coaxial.

[0003] The method for a worker to use the tooling fixture to process cylindrical parts 1 of different specifications in cooperation with a polisher is as follows:

[0004] S1. The worker takes out a cylindrical part 1 of the first specification, puts the cylindrical part 1 on the threaded rod A 5, and then abuts the left end surface of the cylindrical part 1 against the right end surface of the disc A 4. Then the worker adjusts the position of the cylindrical part 1 so that the cylindrical part 1 is coaxial with the disc A 4. Then the worker puts a pressing plate A 6 on the threaded rod A 5, and then threadedly connects a locking nut 7 to the threaded rod A 5. Under the threadedly connected force of the locking nut 7 and the threaded rod A 5, the cylindrical part 1 is just pressed and fixed between the pressing plate A 6 and the disc A 4, thereby achieving the fixation of the cylindrical part 1 of the first specification, as shown in Figure 6 .

[0005] S2. After the cylindrical part 1 of the first specification is fixed, the worker rotates the left end of the rotating shaft 3 with the left hand, the rotating shaft 3 drives the disc A 4 to rotate synchronously, the disc A 4 drives the cylindrical part 1 to rotate synchronously around its axis, and then the worker polishes the outer cylindrical surface of the right end of the cylindrical part 1 with the polisher, thereby achieving the polishing and processing of the right end of the cylindrical part 1 of the first specification.

[0006] S3. After the processing of the cylindrical part 1 of the first specification is completed, the worker unscrews the locking nut 7, then removes the pressing plate A 6, and finally the worker removes the cylindrical part 1 of the first specification.

[0007] S4. The worker repeats the steps S1-S3 multiple times to polish and process the right ends of cylindrical parts 1 of different specifications, respectively.

[0008] However, although the tool fixture can cooperate with the grinder to process different specifications of cylindrical parts 1, there are still the following technical defects in the technology:

[0009] I. In step S1, after the left end face of the cylindrical part 1 is abutted against the right end face of the disc A4, the worker still needs to frequently adjust the position of the cylindrical part 1 to make the cylindrical part 1 coaxial with the disc A4; and the worker needs to frequently adjust the position of the cylindrical part 1 to realize the positioning of the cylindrical part 1, thereby causing a long time to fix the cylindrical part 1, and thereby reducing the processing efficiency of the cylindrical part 1.

[0010] II. In step S2, when the grinding wheel of the grinder grinds the right end of the cylindrical part 1, the right end of the cylindrical part 1 is deformed radially under the action of the grinding force

and the right end of the cylindrical part 1 is required to be not deformed after being ground

[0011] Therefore, an auxiliary tool for improving the processing efficiency of the cylindrical part and improving the processing quality of the cylindrical part is needed. Utility model content

[0037] The left end of pivot 3 extends to the left side of base 2, and a hand wheel 14 is fixed on the extension end, and the worker can rotate the hand wheel 14 to drive the pivot 3 to rotate.

[0038] The worker uses the tool clamp to cooperate with the grinding machine to process cylindrical parts 1 of different specifications, and the method is:

[0039] S1, the worker takes out the cylindrical part 1 of the first specification as Figures 1-2 shown, the cylindrical part 1 is sleeved on the threaded rod B10, and the left end of the cylindrical part 1 is embedded into the sink hole 9 equal to its outer diameter, so that the positioning of the cylindrical part 1 is realized, as Figure 12 shown, since the sink hole 9, disc B8 and pivot 3 are coaxial, when the left end of the cylindrical part 1 is embedded into the sink hole 9, the cylindrical part 1 is coaxial with the disc B8;

[0040] S2, the worker takes out a pressing plate B11 corresponding to the cylindrical part 1 of the first specification, wherein the outer diameter of the support cylinder 12 of the pressing plate B11 is equal to the inner diameter of the cylindrical part 1 of the first specification;Then the worker sleeves the central hole of the pressing plate B11 on the threaded rod B10, and then embeds the support cylinder 12 into the right end of the cylindrical part 1;Then the worker threadedly connects a locking nut 7 on the right end of the threaded rod B10, and under the threaded connection force, the cylindrical part 1 of this specification is just pressed and fixed between the disc B8 and the pressing plate B11, as Figure 13As shown, thereby achieving the fixing of the first specification cylindrical part 1;
