Abstract

The utility model relates to a clamp for drilling a cylinder workpiece. The clamp is characterized in that the clamp consists of a base and a pressure block, a V-shaped groove is arranged at the upper surface of the base, and studs are fixedly arranged at two sides of the V-shaped groove. The pressure block is of a strip-shaped plate, screw holes are arranged at positions close to the two ends of the pressure block, and a space of the two screw holes is equal to that of the two studs on the base. The pressure block is sheathed on the two studs of the base through the screw holes, nuts are sheathed at parts of the two studs, extending out of the pressure block, and the pressure block is fixed on the base by the studs and the nuts. The clamp is used for positioning and then drilling the cylinder workpiece, thereby being capable of reducing the damage to the smoothness on the surface of the workpiece, being high in machining precision and reducing the reject ratio.

Description

The boring clamping device of cylindrical workpiece
Technical field
The utility model relates to a kind of frock clamp, is the clamping device when cylindrical workpiece is holed specifically.
Background technology
At present, in field of machining, operator all must be fixed on cylindrical workpiece to be processed on the operation post anchor clamps of drilling machine when cylindrical workpiece is carried out the Drilling operation operation, and then uses the drill bit on the drilling machine that workpiece is implemented bore operation.The defective that this operational method exists is: the anchor clamps on the drilling machine are double-arm anchor clamps, and its active force to workpiece all concentrates on two jig arm, and therefore after machining, surface of the work all can leave impression, has destroyed the surface flatness of workpiece; In addition, because the anchor clamps on the drilling machine are 2 points to the application point of workpiece, it grips relatively poor, and therefore, workpiece the movement of horizontal direction very easily occurs in process, so that machining accuracy is not enough, and the fraction defective increase.
The utility model content
Problem to be solved in the utility model provides the boring clamping device of a kind of cylindrical workpiece, adopt these anchor clamps to position and rear cylindrical workpiece is carried out Drilling operation, can reduce the destruction to the surface of the work smoothness, and machining accuracy is high, so that fraction defective reduces.
For addressing the above problem, take following scheme:
The characteristics of the boring clamping device of cylindrical workpiece of the present utility model are to comprise base and briquetting, and the upper surface of base has V-shaped groove, and the V-shaped groove both sides all are fixed with double-screw bolt.Described briquetting is that strip is tabular, and it all has screw near on the position at two ends, and the spacing of two screws equals the spacing of two double-screw bolts on the base.Described briquetting is enclosed within by the screw on it on two double-screw bolts of base, and two double-screw bolts stretch out part on briquetting and all overlap nut is arranged, and briquetting is fixed on the base by described double-screw bolt and nut.
The further improvement of the utility model scheme is all bendings downwards of bilateral symmetry position, described briquetting center, and at the equal horizontal buckling in position near two screws, so that the cross section of briquetting is inverted plate-like, thereby so that these anchor clamps are applicable to large-sized cylindrical workpiece, and himself size is less.
Take such scheme, have the following advantages:
Owing on the base of the boring clamping device of cylindrical workpiece of the present utility model V-shaped groove is arranged, there is briquetting the base top, adopt these anchor clamps that cylindrical workpiece is carried out clamping, its bite is 3 points, active force disperses relatively, and clamping face is the plane, therefore, can reduce the destruction to the surface of the work smoothness.And the stationarity of bikini clamping is better, can guarantee that workpiece can not move by occurred level in process, and machining accuracy is higher, can reduce fraction defective.
Description of drawings
Fig. 1 is the structural representation of the boring clamping device of cylindrical workpiece of the present utility model.
The specific embodiment
As shown in Figure 1, the boring clamping device of cylindrical workpiece of the present utility model comprises base 1 and briquetting 4, and the upper surface of base 1 has V-shaped groove, and the V-shaped groove both sides all are fixed with double-screw bolt 2.Described briquetting 4 is that strip is tabular, and it all has screw near on the position at two ends, and the spacing of two screws equals the spacing of two double-screw bolts 2 on the base.Bilateral symmetry position, 4 center of briquetting described in the present embodiment is bending downwards all, and at the equal horizontal buckling in position near two screws, so that the cross section of briquetting 4 is inverted plate-like, the spacing of two screws equals the spacing of two double-screw bolts 2 on the base.Described briquetting 4 is enclosed within by the screw on it on two double-screw bolts 2 of base, and two double-screw bolts 2 stretch out part on briquetting 4 and all overlap nut 3 is arranged, and briquetting 4 is fixed on the base 1 by described double-screw bolt 2 and nut 3.
During use, the nut 3 of the boring clamping device of cylindrical workpiece of the present utility model both sides is outwarded winding, taken off briquetting 4, again cylindrical workpiece to be processed 5 is put in the V-shaped groove on the base 1, then briquetting 4 is packed into, get final product with nut 3 lockings.At this moment, the contact point of cylindrical workpiece 5 and the boring clamping device of cylindrical workpiece of the present utility model lays respectively on two inclined-planes of V-shaped groove on the base 1 and on the lower surface of briquetting 4, i.e. 3 contacts are located, thereby guarantee that moving horizontally can not appear in process in cylindrical workpiece 5.
