Description

Technical Field

[0001] The utility model belongs to the technical field of turning fixtures, and particularly relates to a turning fixture for steel feet with a special shape. Background Technique

[0002] Turning is generally carried out on a lathe to process the inner and outer cylindrical surfaces, end faces, conical surfaces, formed surfaces, threads, etc. of workpieces. After the initial forming of the steel feet, cutting processing is still required.

[0003] At present, the shape of the steel foot workpiece after one-time forming is special, and a fixture with a complex structure needs to be designed for clamping and fixing, resulting in high fixture manufacturing cost and low clamping efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a turning fixture for steel feet with a special shape to solve the above-mentioned existing problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a turning fixture for steel feet with a special shape, which comprises:

[0006] A positioning sleeve, which is of a rotary body structure. A positioning hole is arranged inside the positioning sleeve. An avoidance groove is formed on the outer wall of the positioning sleeve, and the avoidance groove communicates with the positioning hole. One end of the positioning sleeve is fixed on a three-jaw chuck.

[0007] A center rest, which is arranged on one side of the positioning sleeve.

[0008] A jacking rod, which is installed on the center rest and the jacking rod is aligned with the other end of the positioning sleeve.

[0009] As a further description of the above technical scheme:

[0010] The axis of the jacking rod coincides with the axis of the positioning sleeve.

[0011] As a further description of the above technical scheme:

[0012] A positioning inclined plane is arranged at the edge of the positioning hole close to the jacking rod.

[0013] As a further description of the above technical scheme:

[0014] The width of the avoidance groove is smaller than the diameter of the positioning hole.

[0015] As a further description of the above technical scheme:

[0016] A positioning ring is arranged outside the positioning sleeve.

[0017] In summary, due to the adoption of the above technical scheme, the beneficial effects of the utility model are:

[0018] In the present utility model, it is installed on the three-jaw chuck through a positioning sleeve. The steel feet are inserted into the positioning holes from the clearance grooves. The tightening rod abuts against the end of the steel feet so that the steel feet are clamped at the edge of the positioning holes, realizing the quick clamping and fixing of the steel feet on the lathe. The fixture has a simple structure, reduces the manufacturing cost of the fixture, and improves the clamping efficiency of the fixture. Description of the Drawings

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: a turning fixture for steel feet with a special shape, including:

[0028] A positioning sleeve 1, which has a rotary body structure. A positioning hole 2 is provided inside the positioning sleeve 1. A clearance groove 3 is opened on the outer wall of the positioning sleeve 1. The clearance groove 3 communicates with the positioning hole 2. One end of the positioning sleeve 1 is fixed on the three-jaw chuck 4;

[0029] A center rest 5, which is arranged on one side of the positioning sleeve 1;

[0030] A jacking rod 6, which is mounted on the top seat 5, and the jacking rod 6 is aligned with the other end of the positioning sleeve 1;

[0031] The axis of the jacking rod 6 coincides with the axis of the positioning sleeve 1, ensuring that the steel foot can be quickly clamped and fixed;

[0032] The edge of the positioning hole 2 close to the tightening rod 6 is provided with a positioning inclined surface 7, which is used to adaptively position and install the conical end of the steel foot, so as to ensure that the steel foot is quickly clamped and fixed;

[0033] The width of the avoidance groove 3 is smaller than the diameter of the positioning hole 2 to prevent it from falling out of the positioning hole 2;

[0034] A positioning ring 8 is disposed outside the positioning sleeve 1 to facilitate the positioning and installation of the positioning sleeve 1 on the three-jaw chuck 4 .

[0035] Working principle: First, clamp the positioning sleeve 1 on the three-jaw chuck 4, the positioning ring 8 presses against the three-jaw chuck 4, and the three-jaw chuck 4 clamps the positioning sleeve 1. Secondly, insert the middle part of the steel foot from the air avoidance groove 3 into the positioning hole 2. Then, the center seat 5 installed on the moving axis of the lathe moves with the moving axis of the lathe, and the tightening rod 6 supports the end of the steel foot. The positioning bevel 7 adaptively positions and installs the tapered end of the steel foot to ensure that the steel foot is quickly clamped and fixed. Finally, the steel foot is turned.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
