Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lathe processing equipment, in particular to an auxiliary tooling for lathe processing. Background Art
[0002] In processing such as Figure 1 In the structure of the product (1) shown, there are two relatively deep long holes (101) on it. Since the depth of the holes is too large, the vibration of the boring hole is large during processing. Such small and deep holes cannot be processed directly. Now, a lathe is used for processing instead. Therefore, a corresponding fixture needs to be designed and installed on the lathe for processing. Utility Model Content
[0003] The utility model aims to provide an auxiliary tooling for lathe processing to solve the technical problems in the background technology.
[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions:
[0005] An auxiliary tooling for lathe processing includes a main body, which is a cylindrical structure. The main body is provided with mounting holes that pass through the front and rear ends of the main body. The mounting holes are sequentially divided into a first mounting part and a second mounting part from top to bottom. The first mounting part is an arc structure that matches the shape of a product. The axis where the center of the first mounting part is located does not overlap with the axis where the center of the main body is located. A pad is placed in the second mounting part to contact and extrude the bottom of the product in the first mounting part. The shape of the second mounting part matches the shape of the pad. A plurality of fixing holes are provided on the main body along its circumferential direction and communicate with the mounting holes. The fixing screws are connected through threads in the fixing holes to tighten against the outer wall of the product in the mounting hole and the outer wall of the pad.
[0006] Furthermore, a balancing through hole for balancing centrifugal force is provided on one side below the second mounting portion and close to the center of the body, the balancing through hole passes through the front and rear ends of the body, and the balancing through hole is communicated with the mounting hole.
[0007] Furthermore, the balancing through hole is a fan-shaped structure, and the center of the balancing through hole overlaps with the center of the first mounting portion.
[0008] Furthermore, the pad is a rectangular structure, and a first inclined surface is provided on a side below the pad away from the center of the body.
[0009] Compared with the prior art, the auxiliary tooling for lathe processing in the present application has a simple structure and a simple and quick installation method. The product is installed and fixed in the main body by means of a pad and fixing screws. The clamping is stable and it is not easy to shake and affect the accuracy of its subsequent processing operations. The long hole can be processed by installing the installed product body on the lathe. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0017] Specific embodiment 1: Please refer to Figures 1 to 6 In the embodiment of the utility model, the processed product 1 is as follows Figure 1 The long hole 101 of the product 11 shown. The present application adopts an auxiliary tooling for lathe processing, including a main body 2, which is a cylindrical structure. The main body 2 is provided with a mounting hole 201 that runs through the front and rear ends of the main body 2. The mounting holes 201 are, from top to bottom, a first mounting part 201-1 and a second mounting part 201-2. The first mounting part 201-1 is an arc structure that matches the shape of the product 1. The axis where the center of the first mounting part 201-1 is located does not overlap with the axis where the center of the main body 2 is located. The eccentricity D1 between the center of the first mounting part 201-1 and the center of the main body 2 is 18.5-20mm. In the present application, the eccentricity D1 between the center of the first mounting part 201-1 and the center of the main body 2 is 18.5mm.
[0018] A pad 3 is placed in the second mounting part 201-2 to contact and squeeze the bottom of the product 1 in the first mounting part 201-1. The pad 3 in the present application is a rectangular structure, and a first inclined surface 301 is provided on the side below the pad 3 away from the center of the main body 2. The product 1 is pressed tightly in the first mounting part 201-1 through the pad 3 to prevent the product 1 from shaking or other abnormalities. The shape of the second mounting part 201-2 matches the appearance of the pad 3. The main body 2 is provided with a plurality of fixing holes 202 along its circumferential direction, which are connected to the mounting hole 201. The fixing screw 4 is connected through the inner thread of the fixing hole 202 to tighten the outer wall of the product 1 in the mounting hole 201 and the outer wall of the pad 3. At the same time, a plurality of guide holes 203 are provided on the outside of the main body 2 for installing guide columns to position and install the main body 2 and the parts on the lathe.
[0019] In the present application, a balancing through hole 201-3 for balancing centrifugal force is provided on one side below the second mounting portion 201-2 close to the center of the main body 2. The balancing through hole 201-3 runs through the front and rear ends of the main body 2. The balancing through hole 201-3 is connected to the mounting hole 201. The balancing through hole 201-3 is a fan-shaped structure, and the center of the balancing through hole 201-3 overlaps with the center of the first mounting portion 201-1.
[0020] When in use, the product 1 to be processed is inserted into the first mounting part 201-1 of the utility model, and then the pad 3 is inserted along the second mounting part 201-2 to the bottom end surface of the product 1 to support the product 1. The front ends of the pad 3 and the product 1 protrude from the front end of the main body 2, which is convenient for taking the pad 3 and the product 1 after the processing is completed. After the pad 3 is installed, the product 1 and the pad 3 are locked in the main body 2 with the fixing screws 4, and then the auxiliary tooling of the utility model is fixed to the three-jaw chuck or four-jaw chuck on the lathe and locked for processing.
