Abstract
The invention relates to a clamping fixture for drilling a cylindrical workpiece. The clamping fixture is characterized by comprising a base and a pressing block, wherein a V-shaped groove is formed on the upper surface of the base, and studs are fixedly arranged on two sides of the V-shaped groove. The pressing block is in a shape of a strip-type plate, screw holes are formed in positions (close to two ends of the pressing block) of the pressing block, and the separation distance of the two screw holes is equal to that of the two studs on the base. The pressing block is sleeved on the two studs of the base through the screw holes in the pressing block, a nut is sleeved on a part (extending out of the pressing block) of each stud, and the pressing block is fixed on the base through the studs and the nuts. The cylindrical workpiece is drilled after being positioned by the clamping fixture, so that the damage to the surface flatness of the workpiece can be reduced, the processing accuracy is high, and the rejection rate is reduced.
Description
Technical field
The present invention relates to a kind of frock clamp, is the clamping anchor clamps when being used for cylindrical workpiece 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 holed operations, 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 moving of horizontal direction very easily occur in process, make machining accuracy not enough, and fraction defective increases.
Summary of the invention
The problem that the present invention will solve provides the boring clamping anchor clamps of a kind of cylindrical workpiece, adopts these anchor clamps to position the back to the cylindrical workpiece processing of holing, and can reduce the destruction to the surface of the work smoothness, and machining accuracy is high, makes the fraction defective reduction.
For addressing the above problem, take following scheme:
The characteristics of the boring clamping anchor clamps of cylindrical workpiece of the present invention 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.Said briquetting is that strip is tabular, and it is near all there being screw on the position at two ends, and the spacing of two screws equals the spacing of two double-screw bolts on the base.Said briquetting is enclosed within through the screw on it on two double-screw bolts of base, and the part that two double-screw bolts stretch out on briquetting all is with nut, and briquetting is fixed on the base through said double-screw bolt and nut.
Further improvement project of the present invention is all bendings downwards of bilateral symmetry position, said briquetting center; And in position average level bending near two screws; Make the cross section of briquetting be inverted plate-like; Thereby make these anchor clamps 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 anchor clamps of cylindrical workpiece of the present invention V-shaped groove is arranged; There is briquetting the base top, adopts these anchor clamps that cylindrical workpiece is carried out clamping, and 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 anchor clamps of cylindrical workpiece of the present invention.
The specific embodiment
As shown in Figure 1, the boring clamping anchor clamps of cylindrical workpiece of the present invention comprise 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.Said briquetting 4 is that strip is tabular, and it is near all there being screw 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 in the position average level bending near two screws, makes the cross section of briquetting 4 be inverted plate-like, and the spacing of two screws equals the spacing of two double-screw bolts 2 on the base.Said briquetting 4 is enclosed within on two double-screw bolts 2 of base through the screw on it, and the part that two double-screw bolts 2 stretch out on briquetting 4 all is with nut 3, and briquetting 4 is fixed on the base 1 with nut 3 through said double-screw bolt 2.
During use, the nut 3 of the boring clamping anchor clamps of cylindrical workpiece of the present invention 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 anchor clamps of cylindrical workpiece of the present invention lays respectively on two inclined-planes of V-shaped groove on the base 1 on the lower surface with briquetting 4; I.e. 3 contacts are located, thereby guarantee that moving horizontally can not appear in process in cylindrical workpiece 5.
Claims (2)
1. the boring clamping anchor clamps of cylindrical workpiece is characterized in that comprising 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); Said briquetting (4) is that strip is tabular, and it is near all having screw, the spacing of two screws to equal the spacing of two double-screw bolts (2) on the base on the position at two ends; Said briquetting (4) is enclosed within through the screw on it on two double-screw bolts (2) of base, and the part that two double-screw bolts (2) stretch out on briquetting (4) all is with nut (3), and briquetting (4) is fixed on the base (1) through said double-screw bolt (2) and nut (3).
2. the boring clamping anchor clamps of cylindrical workpiece as claimed in claim 1 is characterized in that all bendings downwards of bilateral symmetry position, said briquetting (4) center, and in the position average level bending near two screws, make the cross section of briquetting be inverted plate-like.
