Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lathes, in particular to a Z-direction positioning structure for a lathe chuck. Background Art
[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Lathes are the most important type of metal cutting machine tools. In general machine manufacturing factories, lathes are the most numerous and are also called machine tools. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. The function of a lathe is to cut rotating surfaces of various sizes and shapes, as well as spiral surfaces. The traditional chucks on the market now do not have the function of Z-axis positioning. When processing a single product, the product's steps are generally used for Z-axis positioning. The waste chips generated during the processing remain on the surface of the chuck, causing inaccurate Z-axis positioning of the product and crushing the product. Utility Model Content
[0003] The utility model aims to provide a lathe chuck Z-direction positioning structure, which solves the problems raised in the above-mentioned background technology.
[0004] Technical Solution
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a lathe chuck Z-axis positioning structure, including a chuck, a hole connected to the interior of the chuck is opened on the surface of the chuck, a positioning pin is inserted into the inside of the hole, a mounting head is fixedly connected to the bottom of the chuck, and a placement hole connected to the interior of the chuck is opened on the top of the chuck, and a workpiece is inserted into the inside of the placement hole.
[0006] Furthermore, the interior of the chuck is designed as a cavity.
[0007] Furthermore, an observation hole connected to the inside of the chuck is provided on the outside of the chuck, and a splitting groove connected to the observation hole is provided on the top of the chuck.
[0008] The utility model provides a lathe chuck Z-direction positioning structure, which has the following beneficial effects:
[0009] The lathe chuck has a Z-direction positioning structure, and the main function of the positioning pin is to limit the position. The positioning pin is placed in a hole pre-drilled through the center of the chuck. The size of the positioning pin, chuck and hole are determined according to the size of the workpiece. When the workpiece is placed upside down in the chuck, the positioning pin inside the chuck just touches the bottom of the workpiece, thereby achieving precise and repeated positioning of the workpiece in the Z direction, and the qualified rate of the workpieces is increased to 90%.
[0010] When the locating pin inside the chuck contacts the bottom surface of the workpiece, the contact surface is a line. The contact surface with the workpiece is extremely small, so it is not easy to generate waste chips. Moreover, the locating pin is a slender metal column with a smooth surface. The waste chips of the workpiece are not easy to remain on the surface of the column. The generated waste chips are very easy to clean, and when positioning again, the accuracy will be as accurate as before.
[0011] In order to reduce the consumption of positioning pins, the positioning pins are made of multi-layer metal sleeves. For every sleeve reduced, the model will be reduced by 1cm. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the structure of the utility model;
[0013] Figure 2 It is a cross-sectional view of the structure of the utility model.
[0014] Among them, 1 is a chuck, 2 is a hole, 3 is a mounting head, 4 is a workpiece, 5 is a splitting groove, 6 is an observation hole, 7 is a positioning pin, and 8 is a placement hole. DETAILED DESCRIPTION
[0015] like Figure 1-2 As shown, an embodiment of the utility model provides a Z-axis positioning structure of a lathe chuck, including a chuck 1, the interior of the chuck 1 is of a cavity design, the exterior of the chuck 1 is provided with an observation hole 6 connected to the interior of the chuck 1, the top of the chuck 1 is provided with a splitting groove 5 connected to the observation hole 6, the surface of the chuck 1 is provided with a hole 2 connected to the interior of the chuck 1, a positioning pin 7 is inserted into the hole 2, the bottom of the chuck 1 is fixedly connected with a mounting head 3, the top of the chuck 1 is provided with a placement hole 8 connected to the interior of the chuck 1, and a workpiece 4 is inserted into the placement hole 8.
[0016] Working principle: The lathe chuck has a Z-axis positioning structure. The main function of the positioning pin is to limit the position. The positioning pin is placed in a hole that is pre-drilled through the center of the chuck. The size of the positioning pin, chuck and hole are determined according to the size of the workpiece. When the workpiece is placed upside down in the chuck, the positioning pin inside the chuck just touches the bottom of the workpiece, thereby achieving precise and repeated positioning of the workpiece in the Z axis. The qualified rate of the workpiece is increased to 90%.
