Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of positioning tooling, and particularly relates to a multi-station positioning tooling. Background Art
[0002] When machining the axial surface of a tubular part, it is necessary to perform lateral positioning on the tubular part. Some tubular parts have a relatively thin wall thickness and cannot be directly clamped by the jaws of a numerically controlled lathe. When a common mandrel is used for clamping, the machined part is prone to displacement during the loading and unloading process of the part, resulting in poor positioning effect, poor machining quality, and inability to meet the design accuracy requirements. Summary of the Utility Model
[0003] In order to solve the above problems, the utility model provides a multi-station positioning tooling, which can clamp and position a plurality of tubular parts, facilitating axial surface machining.
[0004] To this end, the technical solution of the utility model is: a multi-station positioning tooling, including a bottom plate, on which a plurality of groups of positioning components are provided; the positioning component includes a first mounting rack and a second mounting rack arranged oppositely, a positioning cylinder is provided on the first mounting rack, and a pushing plate is mounted on the positioning cylinder; a horizontally arranged positioning mandrel is provided on the second mounting rack, and a plurality of cylindrical air bags are embedded on the circumference of the positioning mandrel, and an inflation end communicated with the cylindrical air bags is provided on the second mounting rack, connecting an air charging and discharging device.
[0005] On the basis of the above solution and as a preferred solution of the above solution: a plurality of mounting grooves are provided on the circumferential surface of the positioning mandrel, the cylindrical air bags are sequentially fixed in the mounting grooves, and the cylindrical air bags are communicated with the inflation ports at the ends of the positioning mandrel, and the inflation ports are connected to the inflation ends on the second mounting rack through air pipes.
[0006] On the basis of the above solution and as a preferred solution of the above solution: the cylindrical air bags are made of nylon material.
[0007] On the basis of the above solution and as a preferred solution of the above solution: the cylindrical air bags are evenly arranged on the circumference of the positioning mandrel.
[0008] On the basis of the above solution and as a preferred solution of the above solution: the positioning cylinder drives the pushing plate to move towards the side of the positioning mandrel.
[0009] In the initial state, the pushing plate is located at the leftmost side, and the cylindrical air bags on the positioning mandrel are in a deflated state and are concave; when in use, the tubular part is sleeved on the positioning mandrel, at this time, there is a gap between the positioning mandrel and the tubular part, and at the same time, the positioning cylinder drives the pushing plate to move towards the tubular part, pushing the tubular part to fit with the second mounting rack; then the cylindrical air bags on the positioning mandrel are inflated until the cylindrical air bags are in close contact with the inner wall of the tubular part, thereby firmly fixing the tubular part.
[0010] After the processing of the tubular part is completed, the cylindrical airbag is evacuated by the air charging and discharging device, and the inflated airbag collapses. The positioning cylinder drives the push plate away from the tubular part, facilitating the removal of the processed tubular part from the positioning mandrel.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: A cylindrical airbag is arranged on the positioning mandrel, and the cylindrical airbag is used to fill the gap between the positioning mandrel and the inner wall of the tubular part, ensuring that the tubular part is firmly positioned on the positioning mandrel and not easily displaced; A multi-station positioning component is arranged on the bottom plate to position multiple groups of tubular parts, improving the processing efficiency.
