Abstract
The invention discloses drilling jigs for an elliptical cam. Each drilling jig comprises a fixing screw and a base and is characterized by further comprising an elastic sleeve, liquid plastic, a plunger, a clamping bolt, a gasket and a mounting hole, wherein each elastic sleeve is arranged on the upper surface of the corresponding base and is fixedly arranged on the corresponding base through the corresponding fixing screw; a sealing cavity is arranged between each elastic sleeve and the corresponding base and is used for accommodating the liquid plastic; the liquid plastic in each cavity is infused through the corresponding plunger; each horizontal mounting hole is formed in the corresponding base; each plunger is arranged in the corresponding mounting hole; the tail end of each plunger is in contact with the corresponding clamping bolt; and the outside diameter of each clamping bolt is greater than that of the corresponding plunger. The drilling jigs disclosed by the invention have the beneficial effects that the drilling jigs for the elliptical cam have higher clamping precision; and in addition, the wear of the profile of the elliptical cam is avoided, and the precision of the profile of the elliptical cam is guaranteed.
Description
Technical field
The present invention relates to a kind of cam boring grab, be specifically related to a kind of elliptic cam boring grab, belong to engineering goods field of fixtures。
Background technology
Cam mechanism can realize the movement needs of complexity, it is widely used in various automated and semi-automatic machinery, only need to design suitable cam contour, just driven member can be made to obtain arbitrary desired movement, and simple in construction, compact, design is convenient, therefore at automatic machine tool, light industry and machinery, textile machine, printing machinery, food machinery, package packing machine and electromechanical integrated product are used widely, but there is the shortcoming to be exactly: cam contour required precision is higher, therefore, when cam is made Drilling operation, when to cam circumferentially fixed, requirement can not cause that cam contour weares and teares。
Summary of the invention
In order to solve the deficiencies in the prior art, it is an object of the invention to overcome the defect of prior art, a kind of elliptic cam boring grab is provided, during to elliptic cam circumferentially fixed, the chucking power in clamping process can be finely tuned, there is higher clamp precision, and be not result in elliptic cam profile wear。
For achieving the above object, the present invention adopts the following technical scheme that:
A kind of elliptic cam boring grab, including fixing screw, base, it is characterized in that, also include: resilient sleeve, liquid plastics, plunger, fishbolt, packing ring, installing hole, described base upper surface is provided with described resilient sleeve, described resilient sleeve is fixedly mounted on described base by described fixing screw, Packed cavity is set between described resilient sleeve and base, described cavity is used for holding described liquid plastics, described liquid plastics in described cavity is to be poured into by described plunger, described base offers the described installing hole of a level, described plunger is arranged in described installing hole, the end of described plunger contacts with described fishbolt, the external diameter of described fishbolt is more than the external diameter of described plunger。
Aforesaid a kind of elliptic cam boring grab, it is characterised in that: the lower section of described cavity and described base contacts place vertically offer an air vent。
Aforesaid a kind of elliptic cam boring grab, it is characterised in that: it is provided with described packing ring in the middle of the nut of described fishbolt and described base。
Aforesaid a kind of elliptic cam boring grab, it is characterised in that: described substructure height is more than described resilient sleeve height。
Aforesaid a kind of elliptic cam boring grab, it is characterised in that: described fixture has 2, symmetrical distribution, is clamped in two long end points places of elliptic cam respectively。
Further, blanking space is formed with described two bases below described elliptic cam。
The invention has the beneficial effects as follows: the elliptic cam boring grab of the present invention, during to elliptic cam circumferentially fixed, owing to have employed liquid plastics, this has the characteristic that can transmit pressure to all directions, realize the elliptic cam profile of clamping is slowly clamped equably, the chucking power in clamping process can be finely tuned, there is higher clamp precision, and be not result in elliptic cam profile wear, it is ensured that the precision of elliptic cam profile。
Accompanying drawing explanation
Fig. 1 is that the master of a preferred embodiment of the elliptic cam boring grab of the present invention is depending on partly cuing open structural representation;
Fig. 2 is the plan structure schematic diagram of a preferred embodiment of the elliptic cam boring grab of the present invention。
The implication of accompanying drawing labelling in figure: 1, fixing screw, 2, liquid plastics, 3, elliptic cam, 4, resilient sleeve, 5, base, 6, packing ring, 7, fishbolt, 8, blanking space, 9, air vent, 10, plunger, 11, installing hole, 12, camshaft hole。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention done concrete introduction。
Referring to Fig. 1 and Fig. 2, a kind of elliptic cam boring grab of the present invention, including fixing screw 1, base 5, resilient sleeve 4, liquid plastics 2, plunger 10, fishbolt 7, packing ring 6, installing hole 11, base 5 upper surface is provided with resilient sleeve 4, resilient sleeve 4 is fixedly mounted on base 5 by fixing screw 1, Packed cavity is set between resilient sleeve 4 and base 5, cavity is used for holding liquid plastics 2, liquid plastics 2 in cavity is to be poured into by plunger 10, base 5 is further opened with the installing hole 11 of a level, plunger 10 is arranged in installing hole 11, the end of plunger 10 contacts with fishbolt 7, the external diameter of fishbolt 7 is more than the external diameter of plunger 10。
The lower section of the cavity of the sealing set between resilient sleeve 4 and base 5 and base 5 contact position vertically offer an air vent 9, when by plunger 10 toward pouring liquid plastics in the cavity of the sealing set between resilient sleeve 4 and base 5, fixture is inverted, in such irrigation process, gas in cavity can be got rid of from air vent 9, additionally, when liquid plastics 2 overflows air vent 9, it is appreciated that cavity fills, so that it may tighten plunger。
Preferred as one, it is provided with packing ring 6 in the middle of the nut of fishbolt 7 and base 5。
Preferred as one, base 5 height is more than resilient sleeve 4 height。
In order to realize elliptic cam 3 profile of clamping is slowly clamped equably from the clamping of the two ends of elliptic cam 3 long end, fixture has 2, symmetrical distribution, is clamped in two long end points places of elliptic cam 3 respectively。
Preferred as one, form blanking space 8 with two bases 5 below elliptic cam 3。
The present invention is by twisting fishbolt 7, make fishbolt 7 hold out against plunger 10 and extrude liquid plastics 2, after liquid plastics 2 is squeezed, liquid plastics 2 transmits pressure to all directions, 2 resilient sleeve 4 produce uniform to the elastic deformation at the long end points place of elliptic cam 3 respectively, and the elliptic cam 3 of 2 resilient sleeve 4 is put in clamping together。
The ultimate principle of the present invention, principal character and advantage have more than been shown and described。Skilled person will appreciate that of the industry, above-described embodiment does not limit the present invention in any form, and all employings are equal to the technical scheme that the mode of replacement or equivalent transformation obtains, and all fall within protection scope of the present invention。
