Further, the clamp shell side wall is vertically provided with a long through hole, a pair of positioning screw holes are formed in the two sides of the long through hole in parallel, a positioning pin is movably assembled on the long through hole, a first positioning block is arranged on the surface of the positioning pin, the first positioning block penetrates through the long through hole and the connecting hole and then stretches into the clamp hole, screws are arranged on the two sides of the first positioning block, and the screws are inserted into the positioning screw holes.

Further, the side wall of the clamp shell is vertically provided with a plurality of through holes, the positions of the through holes correspond to the positions of the connecting holes, positioning pins are assembled in the through holes, first positioning blocks are arranged on the surfaces of the positioning pins, the shapes of the first positioning blocks are matched with the through holes, and the first positioning blocks penetrate through the through holes and the connecting holes and then stretch into the clamp holes.

The utility model has the advantages that the utility model has the following advantages,

1. the special positioning centre and the positioning device in the original clamp are changed into a movable structure, and only the centre needs to be replaced every time.

2. This scheme make full use of the terminal cutting face structure of steering gear, the locating pin can insert the corresponding position of anchor clamps lateral wall according to the terminal approximate position of cutting the face of steering gear and carry out the angular positioning, has realized the effect of the workable multiple steering gear of one set of mould, need not to rectify anchor clamps again, labour saving and time saving.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a cross-sectional view of the present invention.

Fig. 3 is a schematic view of the end fixing structure of the steering gear.

The fixture comprises a fixture 1, a fixture hole 2, a tip 4, a positioning pin 5, a fixture shell 6, a steering gear 7, a long through hole 8, a positioning screw hole 9, a first positioning block 10, a screw 11 and a through hole 12.

Detailed Description

The utility model provides a general gear hobbing anchor clamps of remodeling fast, includes

anchor clamps

1, 1 middle part of anchor clamps is run through and is equipped with anchor clamps hole 2, and there is top 4 bottom in anchor clamps hole 2 through threaded connection, it has connecting hole 3 to open on the anchor clamps 1 lateral wall, and the activity is equipped with locating pin 5 in the connecting hole 3, 1 outside cover of anchor clamps is equipped with anchor clamps shell 6 that is used for sealing

anchor clamps

1, and 6 inboards of anchor clamps shell are equipped with annular boss 7.

Further, 6 lateral walls of anchor clamps shell are equipped with slotted hole 8 perpendicularly, and the parallel of 8 both sides of slotted hole is equipped with a pair of positioning screw 9, and the activity is equipped with locating pin 5 on the slotted

hole

8, 5 surfaces on the locating pin are equipped with first locating piece 10, first locating piece 10 stretches into anchor clamps hole 2 after passing slotted hole 8, connecting hole 3 in, first locating piece 10 both sides are equipped with screw 11, screw 11 inserts in the positioning screw 9.

Further, the anchor clamps lateral wall is equipped with a plurality of through-holes 12 perpendicularly, and the position of through-hole 12 corresponds with the position of connecting hole 3, is equipped with locating pin 5 in the through-hole 12, 5 surfaces on the locating pin are equipped with first locating piece 10, and the shape and the through-hole 12 of first locating piece 10 match, stretch into in the anchor clamps hole 2 after first locating piece 10 passes through-hole 12, connecting hole 3.

When the structure is used, only the steering gear 7 with different lengths is needed, the top 4 with proper height is selected, the bottom of the clamp hole 2 is screwed, the steering gear 7 is placed into the clamp hole 2, because the tail end of the steering gear 7 needs to cut a plane for being connected with a universal joint below an automobile steering wheel, therefore, the steering gear 7 is rotated to a cutting surface to a connecting hole 3, the clamp shell 6 is sleeved, the clamp shell 6 is rotated to the connecting hole 3 corresponding to the long through hole, the positioning pin 5 is inserted finally, the end part of the first positioning block 10 of the positioning pin 5 supports against the cutting surface, the screw 11 on the positioning pin 5 is screwed into the positioning screw hole 9, and the steering gear 7 is prevented from rotating and shaking. Finally, the positioning of the steering gear 7 is achieved.

Under the unchangeable condition of other characteristics, the connection structure of anchor clamps 1 and locating pin 5 in this structure can also be following structure, and 6 lateral walls of anchor clamps shell are equipped with a plurality of through-holes 12 perpendicularly, are equipped with locating pin 5 in the through-hole 12, the locating pin surface is equipped with first locating piece 10, and the shape and the through-hole 12 of first locating piece 10 match. The positioning pin 5 is directly inserted into the through hole 12 and the connecting hole 3 and finally abuts against the cutting face at the tail end of the steering gear, the structure is kept not to shake by means of friction between the first positioning block 10 and the through hole 12, and finally the steering gear 7 is positioned. The structure is simple and quick, the cost is lower, and a positioning screw hole is not required to be designed.
