Abstract
The utility model discloses a tension device of a spindle cutting tool of a numerical control machine. The utility model is realized by a technical scheme which is characterized in that the inner hole of the spindle is provided with a pull rod, a joint of the pull rod and a pull nail and the tension device is characterized in that a bush is arranged between the inner hole of the spindle and the joint of the pull rod, the inside of the spindle is provided with a location pin in the radial direction and at the position of the bush while the inside of the spindle is also provided with a location screw in the axial direction, the cone surface of the location screw embeds into the cone surface in the location pin. The utility model increases the bush structure between the pull rod joint and the spindle and the bush can be regularly replaced as a throwaway unit, so the wear problem of the inner hole of the spindle, thereby keeping the tension effect of the cutting tool for a long time.
Description
Technical field
The utility model relates to the Digit Control Machine Tool apparatus field, more particularly, relates to a kind of main shaft of numerical control machine tool cutter tensioning mechanism.
Background technology
Most of Digit Control Machine Tools adopt pull bar, rod head, blind rivet structure more, as shown in Figure 1, tie rod end steady brace joint, the head of blind rivet embeds rod head, blind rivet connects handle of a knife, axial force of transmitting by pull bar and rod head (rod head adopts forms such as steel ball and elastic card claw more), blind rivet are realized the tension to the cutter handle of a knife.Said structure can be realized the quick replacing of cutter, but rod head influences tension effect causing the main shaft bore area wearing and tearing that contact with rod head in the motion process repeatedly.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of main shaft of numerical control machine tool cutter tensioning mechanism is provided.
The utility model main shaft of numerical control machine tool cutter tensioning mechanism, be achieved by following technical proposals, the main shaft endoporus is provided with pull bar, rod head and blind rivet, it is characterized in that, between described main shaft endoporus and the rod head lining is set, radially in the lining position shop bolt is set in the main shaft, dog screw is set in the main shaft vertically, the taper seat of described dog screw embeds the shop bolt internal conical surface.
Main shaft side face described in the utility model is provided with counterbore, and the shop bolt end is arranged in the counterbore.
The utility model has increased bush structure between rod head and main shaft, lining can regularly replace as consumable accessory.Eliminated the wear problem of main shaft endoporus like this, maintenance that can be permanent is to the tension effect of cutter.Lining adopts suitable material and Technology for Heating Processing can reach certain rigidity, increases its wearability, thereby has increased its service time, and change conveniently.
Description of drawings
Fig. 1 is a main shaft of numerical control machine tool cutter tensioning mechanism existing structure schematic diagram;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, main shaft of numerical control machine tool cutter tensioning mechanism existing structure, the main shaft endoporus is provided with pull bar 1, rod head 2 and blind rivet 3, tie rod end steady brace joint, the head of blind rivet embeds rod head, and blind rivet connects handle of a knife 4.
As shown in Figure 2, the main shaft endoporus is provided with pull bar 1, rod head 2 and blind rivet 3, tie rod end steady brace joint, and the head of blind rivet embeds rod head, and blind rivet connects handle of a knife 4; Lining 5 is set between main shaft endoporus and the rod head, radially shop bolt 6 is set in the main shaft in the lining position, dog screw 7 is set in the main shaft vertically, and the taper seat of dog screw embeds the shop bolt internal conical surface, and inherent shop bolt taper seat below, shop bolt hole is provided with flexible member 8.
During mounting bush, lining is put into spindle hole, tighten stop screw, the stop screw taper seat enters the shop bolt internal conical surface, under its effect position-limitting pin is moved downward, and lining is inserted in the position-limitting pin end, and lining is played positioning action.During the dismounting lining, loosen stop screw, make the stop screw taper seat withdraw from the position-limitting pin taper seat, position-limitting pin rises under the effect of flexible member, and its top breaks away from lining, removes the positioning action to lining, and lining can take out.The shop bolt stroke is limited by counterbore on the main shaft.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
Claims (2)
1. main shaft of numerical control machine tool cutter tensioning mechanism, the main shaft endoporus is provided with pull bar, rod head and blind rivet, it is characterized in that, between described main shaft endoporus and the rod head lining is set, radially shop bolt is set in the main shaft in the lining position, dog screw is set in the main shaft vertically, and the taper seat of described dog screw embeds the shop bolt internal conical surface.
2. main shaft of numerical control machine tool cutter tensioning mechanism according to claim 1 is characterized in that described main shaft side face is provided with counterbore, and the shop bolt end is arranged in the counterbore.
