A tooling for machining shaft pin parts

Abstract

This utility model discloses a tooling for machining shaft pin parts, relating to the field of machining tooling technology. It includes a lathe body, a support assembly fixedly mounted on the rear side of the lathe body, a movable stage movably mounted on the support assembly, a locking assembly fitted onto the movable stage, and a connecting frame extending towards the front of the lathe body from the top of the movable stage. This utility model design uses the movable stage to support and move a positioning frame, thereby adjusting the position of the positioning frame according to the length of the workpiece to be machined. When workpiece positioning is required, the movable stage is first fixed by the positioning assembly, and then the position of the positioning seat is adjusted according to the diameter of the workpiece, so that the rollers on the positioning seat abut against the surface of the workpiece. During machining, the lathe body passes through the clearance opening at the front end of the positioning frame, thus assisting the lathe spindle in positioning the workpiece without hindering machining, preventing workpiece movement, and ensuring machining quality.

[0023] In this embodiment, the support component includes a fixed plate 2, which is fixedly installed on the rear side wall of the lathe body 1 by bolts. A number of groups of support plates 3 are welded to the side of the fixed plate 2. The support plate 3 is of an "L" - shaped structure. The top of the support plate 3 is fixedly installed with an installation platform 4. Two guide rails 5 are fixedly installed on the top surface of the installation platform 4. The two guide rails 5 are parallel to the main shaft of the lathe body 1. The moving table 6 is slidably installed on the guide rails 5. The two guide rails 5 are symmetrically arranged. A clamping groove 51 is formed on the outer side wall of the guide rail 5. Clamping blocks 62 are provided at both ends of the moving table 6 and are matched with the clamping groove 51. The clamping blocks 62 are slidably installed in the clamping groove 51. The locking component includes a pressing plate 7. A number of groups of first guide rods 8 are fixedly installed on the top of the pressing plate 7. The first guide rods 8 are slidably installed on the moving table 6. A connecting screw rod 9 is fixedly installed in the middle of the pressing plate 7. A first through - hole 61 is formed on the moving table 6. The connecting screw rod 9 is fitted and installed in the first through - hole 61. The top of the connecting screw rod 9 is threadedly fitted with a first nut 10. A first conical surface 52 is provided on the inner side wall of the guide rail 5.

When rotating the adjusting bolt 18, the positioning seat 15 moves along the radial direction of the main shaft. When positioning the workpiece, the positioning seat 15 contacts the workpiece through the roller 16, so as to cooperate with the main shaft to position the workpiece.

[0025] In use, the tooling assembly is fixed to the rear side wall of the lathe body 1 by the fixing plate 2. The positioning frame 14 is moved by the moving table 6, thereby adjusting the position of the positioning frame 14 according to the length of the workpiece to be processed. When the workpiece needs to be positioned, the first nut 10 is tightened first. With the cooperation of the first nut 10 and the connecting screw 9, the pressure plate 7 moves closer to the moving table 6, thereby fixing the moving table 6. Then, the position of the positioning seat 15 is adjusted according to the diameter of the workpiece by adjusting the adjusting bolt 18, so that the roller 16 on the positioning seat 15 abuts against the surface of the workpiece. During processing, the cutting tool passes through the clearance opening 141 at the front end of the positioning frame 14 to process, thereby assisting the lathe spindle in positioning the workpiece without hindering the processing, avoiding workpiece jump, and thus ensuring processing quality.
