Description

Technical Field

[0001] This utility model relates to the field of turning clamping technology, specifically a turning clamping and positioning device for semi-finished round bars. Background Technology

[0002] In existing lathes, a three-jaw chuck is typically used to clamp and fix the workpiece during turning, and then a locator (such as a center pin) is used to support and position the workpiece. However, the clamping and positioning mainly relies on a conical center for positioning and air pressure for tightening. This method is very difficult to control the size, length, and force of the carbide blank, which can easily lead to loosening of the clamping during the machining process. Excessive air pressure can also cause breakage, resulting in a very low product qualification rate. At the same time, most existing locators are installed by interference fit, which can become irremovable and replaceable due to corrosion after long-term use. To address these problems, we propose a clamping and positioning device for turning semi-finished round bars. Utility Model Content

[0003] The purpose of this utility model is to provide a turning clamping and positioning device for semi-finished round bars to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a turning clamping and positioning device for a round bar semi-finished product, comprising a disc, one end face of which is coaxially fixedly connected to one end of a cylindrical seat, the other end of which is fixedly connected to one end of a cross seat, and the other end of which is fixedly connected to a conical portion.

[0005] The other end face of the disc is coaxially fixedly connected to one end of the threaded rod. The other side of the threaded rod is fitted with an internal threaded ring through a threaded structure. An adjusting cap is fixedly fitted to one side of the internal threaded ring. An adjusting assembly is rotatably connected to the other side of the internal threaded ring. Several anti-slip rods are fixedly connected to the outside of the adjusting assembly. The anti-slip rods are evenly distributed around the circumference.

[0006] Preferably, at least three anti-slip rods are evenly distributed around the circumference.

[0007] Preferably, the adjusting assembly includes a movable ring, a movable seat, a first connecting rod, a second connecting rod, a support bar, a sliding opening, a fixed ring, and a fixed seat. The movable ring is rotatably sleeved on the outside of the internal threaded ring. A plurality of movable seats are fixedly connected to the outer wall of the movable ring. Each of the movable seats is hinged to one end of the first connecting rod. The other end of the first connecting rod is hinged to one side of the support bar. Each support bar is fixedly connected to an anti-slip rod. The middle of the first connecting rod is hinged to the middle of the second connecting rod on both sides. One end of the second connecting rod is hinged to a fixed seat. Each fixed seat is fixedly connected to the outer wall of the fixed ring. The fixed ring is fixedly sleeved on the end of the threaded rod away from the disc.

Example

[0017] Reference Figure 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, at least three anti-slip rods 9 are evenly distributed around the circumference. The arrangement of multiple anti-slip rods 9 ensures the support position.
