Description

A Turning Fixture for Butterfly Parts

technical field

The utility model relates to a clamp, in particular to a turning clamp for butterfly parts, belonging to the technical field of mechanical tools.

Background technique

Butterfly parts are special parts that are difficult to process. For some thin butterfly parts, it is even more difficult to process. However, when the existing thin butterfly parts are processed, they mainly rely on the chuck to directly clamp the thin parts. Butterfly parts like this are clamped and then processed, but there are many problems and hidden dangers in this clamping method. First of all, such a clamping method has a large amount of turning deformation during processing, and at the same time, the operation is cumbersome and The production efficiency is low, the labor intensity of the workers is high, and the rate of waste and defective products is also high, which cannot meet the existing production capacity.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a turning fixture for butterfly parts that is simple to operate and can effectively improve the processing efficiency of thin butterfly parts.

In order to achieve the above object, the technical solution adopted by the utility model is: a turning fixture of a butterfly part, the butterfly part includes a substrate to be turned, a connecting shaft fixedly arranged on the substrate to be turned, and a connecting shaft that runs through the substrate to be turned and the The installation hole of the connecting shaft, the clamp includes a positioning shaft and a clamping sleeve, the end of the connecting shaft is docked with the end of the positioning shaft; the clamping sleeve is sleeved above the positioning shaft and the connecting shaft, where The inner hole of the clamping sleeve above the connecting shaft is a conical hole; an annular groove is arranged on the connecting shaft; a spring ring is arranged on the annular groove; the spring ring is in the conical hole.

As a further improvement of the utility model, a positioning sleeve is sleeved outside the clamping sleeve; one end surface of the positioning sleeve is in contact with the end surface of the substrate to be turned.

As a further improvement of the present invention, a first gap is provided between the inner wall at the end of the positioning sleeve and the opposite end surface of the clamping sleeve.

As a further improvement of the utility model, a second gap is provided on the opposite end surface of the connecting shaft end and the positioning shaft.

As a further improvement of the utility model, the clamping sleeve is also provided with a pull rod.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The turning fixture of the butterfly part of the utility model, by moving the clamping sleeve to the left relative to the positioning shaft, under the action of the conical surface of the inner hole at the right end of the clamping sleeve, the inner diameter of the spring ring becomes smaller and then deformed uniformly to make it Radial shrinkage to achieve automatic centering and clamping of the workpiece, fast clamping, automatic centering, high centering accuracy, compact structure, stable work, improved workpiece processing efficiency, guaranteed processing quality, and met the actual production needs , suitable for large-scale applications.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Accompanying drawing 1 is the structural representation of the turning fixture of butterfly part of the present utility model;

Among them: 1. Substrate to be turned; 2. Connecting shaft; 3. Mounting hole; 4. Positioning shaft; 5. Clamping sleeve; 6. Conical hole; 7. Conical surface; 8. Annular groove; 9. Spring circle; 10, pull rod; 11, first gap; 12, second gap; 13, positioning sleeve.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Embodiment 1, as shown in the accompanying drawing 1, a turning fixture of a butterfly part of the present invention, the butterfly part in the present invention includes a substrate to be turned 1, a connecting shaft 2 fixedly arranged on the substrate to be turned 1 And through the mounting hole 3 of the substrate 1 to be turned and the connecting shaft 2, the clamp includes a positioning shaft 4 and a clamping sleeve 5, and there is a gap between the end of the connecting shaft 2 and the positioning shaft 4 to prevent interference ; The clamping sleeve 5 is sleeved on the positioning shaft 4, one end of which is above the connecting shaft 2; the inner hole of the clamping sleeve 5 above the connecting shaft 2 is a conical hole 6, and the conical hole 6 is clamped A conical surface 7 is formed inside the sleeve 5 ; an annular groove 8 is arranged on the connecting shaft 2 ; a spring ring 9 is arranged on the annular groove 8 ; and the spring ring 9 is located in the conical hole 7 .

In order to better realize the clamping function of the fixture, a positioning sleeve 13 is sleeved outside the clamping sleeve 5; one end face of the positioning sleeve 13 is in contact with the opposite end face of the substrate 1 to be turned.

The annular groove 8 increases the clamping area between the spring ring 9 and the connecting shaft, so as to improve the clamping force.

In order to facilitate the clamping sleeve to move left and right along the positioning shaft 4, a pull rod 10 is arranged on the clamping sleeve, and the other end of the pull rod 10 is connected with a tensioning device (not shown). After the ends of the positioning sleeve 13 are docked, the tensioning device drives the pull rod 10 to move to the left, and the pull rod 10 simultaneously drives the clamping sleeve 5 to move to the left relative to the positioning shaft 4. Under the action of the conical surface 7 at the right end of the clamping sleeve 5, Make the inner diameter of the spring ring 9 smaller and then deform it evenly to make it radially smaller, so as to realize automatic centering and clamping of the workpiece. Leave a certain first gap 11; the connecting shaft end and the opposite end surface of the positioning shaft are provided with a second gap 12; when the tensioning device drives the pull rod 10 to move to the right, the pull rod 10 pushes the clamping sleeve 5 to move to the right, and the conical surface 7 and the spring ring 9 are loosened, and the spring ring 9 returns to its original shape under the action of the elastic force, thereby releasing the workpiece. Wherein the positioning sleeve 13 is connected with the main shaft part of the machine tool, and is fixed relative to the positioning shaft 4. At the same time, for the convenience of relative movement, the positioning sleeve 13 and the clamping sleeve 5, and the clamping sleeve 5 and the positioning shaft 4 are clearance fits. .

The utility model realizes fast clamping and unloading, automatic centering, high centering precision, compact structure, stable work, improved workpiece processing efficiency, guaranteed processing quality, meets the needs of actual production, and is suitable for large-scale application.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
