Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 2, a hexagonal axle adds clamping apparatus, including lathe 1, install a plurality of guide rails 2 on the lathe 1, form T type groove 3 between two guide rails 2, sliding connection has backup pad 4 in the T type groove 3, backup pad 4 upper end is fixed with circular boss 5, be equipped with blind hole 6 in the circular boss 5, blind hole 6 internal rotation is connected with rotary disk 7, be equipped with hexagonal groove 8 on the rotary disk 7, the equipartition is fixed with a plurality of first lugs 9 on the terminal surface of rotary disk 7, be equipped with through-hole 10 on the first lug 9, circular boss 5 upper end is fixed with second lug 11, sliding connection has bolt 12 associated with through-hole 10 about in the second lug 11.

And transverse plates positioned above the guide rails 2 are fixed on two sides of the supporting plate 4, and fastening bolts 13 are connected to the transverse plates in a threaded manner.

And a plurality of rollers 14 are uniformly arranged between the circular boss 5 and the rotating disc 7.

When the utility model is used, the indication directions or position relations of the terms of front, back, left, right, up and down are based on the front view, the initial state is that the fastening bolt 13 is in a loosening state, the support plate 4 slides in the T-shaped groove 3, the support plate 4 moves to a proper position of the machine tool 1 according to the actual requirement, the fastening bolt 13 is screwed down to ensure that the fastening bolt 13 and the upper end surface of the guide rail 2 are in a locking state, thereby ensuring the position of the support plate 4, preventing the support plate 4 from moving, then inserting one end of the hexagonal shaft into the hexagonal groove 8, the hexagonal groove 8 is not through, so that one end of the hexagonal shaft is tightly attached to the rotating disc 7 in the hexagonal groove 8, the rotating disc 7 is positioned in the blind hole 6 of the circular boss 5, effectively preventing the hexagonal shaft from moving axially in the processing process, and finally moving the bolt 12, the bolt 12 is inserted into the through hole 10 of the first lug 9, the first lug 9 is fixedly connected with the rotating disc 7, the second lug 11 is fixedly connected with the circular boss 5, and the bolt 12 is matched with the through hole 10, so that the rotating disc 7 is fixed with the circular boss 5, and the rotating motion of the hexagonal shaft is effectively prevented, and similarly, the other end of the hexagonal shaft is also provided with a device which is the same as the device, so that the two ends of the hexagonal shaft are in a fixed state, the hexagonal shaft can not axially move or rotate, the fixing effect is good, the positioning is accurate, the end face of the hexagonal shaft is finely milled or the boring processing is carried out on the end face of the hexagonal shaft according to the actual processing requirement, the processing precision is ensured, in the processing process, when the end face of the hexagonal shaft is processed, the bolt 12 is pulled out, the bolt 12 is separated from the through hole 10, the hexagonal shaft is rotated, and the two ends of the hexagonal shaft are both attached to the rotating disc 7, a plurality of rollers 14 are installed to the equipartition between circular boss 5 and the rotary disk 7, and then rotary disk 7 can be at 5 internal rotation motion of circular boss, the hexagonal axle also rotates along with rotary disk 7, when another terminal surface of hexagonal axle is rotatory to the processing position, bolt 12 cooperatees with through-hole 10, circular boss 5, rotary disk 7 and hexagonal axle are together fixed, rotary motion can not take place for the hexagonal axle, circulate in proper order, the machining efficiency of hexagonal axle has been improved greatly, the location effect is good, the machining precision is guaranteed, after the processing is accomplished, loosen fastening bolt 13, sliding support plate 4, just can take out the hexagonal axle.

The utility model discloses more traditional equipment has following benefit: 1) the structure is ingenious, the sliding support plate 4 is arranged on the basis of the guide rail 2 of the existing machine tool 1, the hexagonal shaft can be positioned at a proper position according to the machining requirement in time, the machining range is wide, and the operation is simple; 2) the round boss 5 is internally provided with a blind hole 6 structure, the rotating disc 7 rotates in the blind hole 6, and the hexagonal groove 8 in the rotating disc 7 is not communicated, so that the hexagonal shaft is effectively prevented from moving axially; 3) utilize the cooperation of bolt 12 and through-hole 10, when the hexagonal axle needs to add man-hour, in bolt 12 inserts through-hole 10, circular boss 5, rotary disk 7 and hexagonal axle are fixed together, and then prevent that the hexagonal axle from taking place rotary motion, when the hexagonal axle needs to adjust the machined surface, bolt 12 breaks away from with through-hole 10, and the hexagonal axle is along with rotary disk 7 at circular boss 5 internal rotation motion, realizes the effect of quick replacement machined surface.
