Description

a fixture

technical field

The utility model relates to the field of mechanical engineering, in particular to a clamp.

Background technique

With the continuous development of my country's manufacturing industry, the market demand for various fixtures is increasing.

We know that in the field of mechanical manufacturing, machining eccentric circles with lathes is one of the more important processing techniques. However, generally speaking, after the part to be processed is clamped on the lathe, its axis of rotation is in line with its own axis, and the center of the machined hole is located on the axis of rotation of the part, so the processed hole is a concentric hole; For some parts, it is necessary to process the eccentric hole, that is to say, the axis of the part and the center of the eccentric hole are not collinear; therefore, it is often a big problem to process the eccentric hole with a lathe.

Therefore, how to conveniently process eccentric holes is a technical problem that those skilled in the art need to solve.

Utility model content

The purpose of the utility model is to provide a fixture which can solve the problem of inconvenient turning of eccentric holes.

In order to achieve the above object, the utility model provides a fixture, which includes a Morse taper handle and a clamp body that is interference fit with one end of the Morse taper handle, and the inside of the Morse taper handle is provided with a piston that is connected to the lathe. A pull rod connected to the cylinder, the other end of the pull rod is connected with a pull ring that is located at the edge of the clamp body and can move toward the clamp body to fix the part to be processed, the axis of the pull rod is connected with the clamp body A distance is set between the axes so that the turning tool can carve out an eccentric circle or an eccentric hole on the part to be processed.

Preferably, the distance between the axis of the clamp body and the axis of the tie rod is less than or equal to 3 mm.

Preferably, the edge of the clamp body is also provided with a positioning column.

Preferably, the length of the positioning column is greater than the thickness of the part to be processed.

Preferably, the pull ring and the pull rod are connected by bolts.

Preferably, the pull ring is configured as two claws or three claws.

With respect to the above-mentioned background technology, the utility model provides a fixture, including a Morse taper shank and a clamp body with an interference fit with one end of the Morse taper shank, and one end of the Morse taper shank is connected to the piston cylinder of the lathe The other end of the pull rod is connected to the pull ring that is located at the edge of the clamp body and can move toward the clamp body to fix the part to be processed. A gap between the axis of the pull rod and the axis of the clamp body is provided to allow the turning tool to process the part. The distance of the car out of the eccentric circle or eccentric hole. With this setting method, the part to be processed is fixed by the pull ring set on the clamp body. Since the axis of the pull rod and the axis of the clamp body are not collinear, there is a distance between the two axes; Specifically, when the part to be processed on the clamp body is rotated, the turning tool can process the eccentric circle or eccentric hole of the part to be processed; To determine the distance between the axis of the tie rod and the axis of the clamp body. In this way, the turning tool can process eccentric circles or eccentric holes on the part to be processed, thereby realizing the purpose of conveniently processing eccentric circles or eccentric holes.

Detailed ways

The core of the utility model is to provide a fixture, which can conveniently turn the eccentric hole.

In order to enable those skilled in the art to better understand the solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Fig. 1 to Fig. 3; Fig. 1 is a schematic structural view of the fixture provided by the utility model; Fig. 2 is a schematic structural view of parts to be processed in Fig. 1; Fig. 3 is a schematic top view of Fig. 1.

The fixture provided by the utility model includes a Morse taper shank 1 and a clamp body 2 that is interference-fitted with one end of the Morse taper shank 1, and a pull rod 5 that is connected to the piston cylinder of the lathe is provided inside the Morse taper shank 1 The other end of the pull rod 5 is connected to the pull ring 3 that is located at the edge of the clamp body 2 and can move toward the clamp body 2 to fix the part 9 to be processed, and the axis of the pull rod 5 and the axis of the clamp body 2 is provided with a The turning tool treats the distance of the eccentric circle or eccentric hole of the processed part 9.

With this setting method, the part 9 to be processed is fixed by the pull ring 3 arranged on the clamp body 2, and the retraction of the pull rod 5 drives the pull ring 3 to move toward the clamp body 2, thereby fixing the part 9 to be processed on the On the clamp body 2.

In addition, since the axis of the pull rod 5 and the axis of the clamp body 2 are not collinear, there is a distance between the two axes; , the turning tool can process the eccentric circle or eccentric hole of the part 9 to be processed; that is to say, we can determine the axis of the tie rod 5 and the clamp body according to the distance between the center of the required eccentric circle or eccentric hole and the center of the part 9 to be processed The distance between the axes of 2. In this way, the turning tool can process an eccentric circle or an eccentric hole on the part 9 to be processed, thereby realizing the purpose of conveniently processing an eccentric circle or an eccentric hole.

In addition, we can set the distance between the axis of the clip body 2 and the axis of the tie rod 5 to be less than or equal to 3 mm.

Specifically, if the distance between the center of the required eccentric circle or eccentric hole and the center of the part 9 to be processed is 1 mm, that is, the eccentricity of the part 9 to be processed is 1 mm, then the axis of the clamp body 2 and the distance between the axis of the clamp body 2 and the tie rod 5 The distance between the axes is set to 1mm; similarly, if the distance between the center of the required eccentric circle or the eccentric hole and the center of the part 9 to be processed is large, we can set the axis of the clamp body 2 to the axis of the pull rod 5 The distance between them is set to 3mm; of course, according to the actual situation, we can also set the distance between the axis of the clamp body 2 and the axis of the tie rod 5 to other distances, which will not be repeated here.

In addition, we can also set a positioning column 4 on the edge of the clamp body 2; that is to say, we can use the positioning column 4 to determine the position of the part 9 to be processed; of course, the position of the positioning column 4 can be adjusted according to different parts to be processed. 9 and set, will not repeat them here.

In addition, we can also set the length of the positioning column 4 to be greater than the thickness of the part 9 to be processed; Reliable, enabling easy machining of eccentric circles or eccentric holes. Of course, the position of the positioning column 4 should avoid the surface to be processed of the part 9 to be processed, and will not be described in detail herein.

In addition, we can connect the pull ring 3 and the pull rod 5 with bolts. Of course, we can also use other connection methods to connect the pull ring 3 and the pull rod 5 , which will not be repeated here.

In addition, we can set the pull ring 3 as two claws or three claws. That is to say, we can use the two-jaw or three-jaw pull ring 3 to fix the part 9 to be processed, so as to realize the machining of eccentric circles or eccentric holes.

The clamp provided by the utility model has been introduced in detail above. In this paper, specific examples are used to illustrate the implementation of the present utility model, and the descriptions of the above embodiments are only used to help understand the method and the core idea of the present utility model.
