Description

Part clamp for turning and milling combined machining center

Technical Field

The utility model may relate to a turning and milling combined machining center and a tool clamp, in particular to a part clamp for the turning and milling combined machining center.

Background

The turning and milling combined machining center can clamp parts at one time to realize multi-process and multi-content machining such as turning and milling. The part is connected with the main shaft or the auxiliary main shaft through a special fixture and is processed through the B shaft. However, some parts need to meet the requirements of angles or positions with some rough machined contents during finish machining, namely, the direction limitation exists during finish machining of clamping parts. In addition, in the process of mutually transferring parts between the main shaft and the auxiliary main shaft, in order to avoid the processing area of the parts, the positions of the parts and the chuck jaws also need to meet certain angle requirements. Therefore, when the clamp and the part are clamped at each time, the part can be machined only after being aligned again and meeting a specific angle, the production preparation time is long, and the machining efficiency is extremely low.

Disclosure of Invention

The technical problems solved by the utility model are as follows: the part clamp for the turning and milling combined machining center is matched with the realization of efficient and accurate part transfer process design in the turning and milling combined machining center.

The technical scheme of the utility model is as follows: the utility model provides a turn-milling is part anchor clamps for combined machining center, anchor clamps include the base, the one end terminal surface of base is provided with limit structure, limit structure can cooperate with the part structure.

Furthermore, the limiting structure is a cylinder.

Further, the base also comprises a handle part, and the handle part is fixedly connected with a shaft of the turning and milling composite machining center.

Furthermore, the handle part is fixedly connected with a B shaft of the turning and milling composite machining center.

Furthermore, the handle part is inserted into a tool shank of a B shaft of the turning and milling combined machining center and is fixedly connected with the B shaft.

Furthermore, mutually matched planes are arranged in the handle part and the knife handle.

The utility model has the beneficial effects that: the clamp is connected with a B shaft of a machine tool through the base, so that parts are transferred and processed between the main shaft and the auxiliary main shaft at a specific angle, and the problems that the rotary parts are difficult to align and cannot meet the processing angle during clamping are solved. And the three-jaw chuck does not have directionality when clamping the part, and the quick change anchor clamps and hydraulic chuck can satisfy the continuity of course of working through program control, can realize the quick trade of part and produce, improve the machining efficiency of part.

fig. 2 is a schematic view of the installation state of the clamp in the embodiment of the utility model.

In the figure: the tool comprises a positioning pin 1, a base 2, a handle 3, a part 4, a tool handle 5, a plane 6 and a clamp 7.

Detailed Description

As shown in fig. 1, the part clamp for the turning and milling composite machining center comprises a base, wherein a limiting structure is arranged on one end face of the base, and the limiting structure can be matched with a part structure. The part 4 is stopped against the end face, and the rotation of the part relative to the central shaft for turn-milling composite machining is restrained through the matching of the part and the limiting structure. In this embodiment, the limiting structure is cylindrical and is a positioning pin 1. The base further comprises a handle part 3, the handle part is a cylinder in the embodiment, and the handle part 3 is fixedly connected with a B shaft of the turning and milling composite machining center. The handle part is inserted into a tool shank 5 of a B shaft of the turning and milling combined machining center and is fixedly connected with the B shaft. The handle part and the knife handle are internally provided with mutually matched planes 6.

As shown in figure 2, the handle part 3 is designed according to the standard phi 20, the handle part is connected with a B shaft of a machine tool through the tool shank 5, the direction and the rotating angle of the clamp 7 can be determined through the design of the handle part flattening plane, a part is arranged on the clamp through two positioning pins, and the clamping angle of the part is determined at the moment. The angle between the main shaft orientation position and the actual position of the C0 is determined by aligning the position of the machine tool C0, and the angle value is input into a program segment C13 (B-axis orientation value). And moving the B shaft to send the clamp to the C2 shaft (auxiliary main shaft), determining whether the position of a C2 shaft clamping jaw can avoid a part machining area, adjusting the parameters of the C2 shaft as required, inputting the parameters into an L1000 subprogram clamping jaw angle value R52, and correspondingly increasing a R52 value in the C13, so that the B shaft directional installation and part transmission can be realized, and the quick production change is realized.
