Description
Technical field
The utility model relates to a kind of hold down gag for step parts in small-bore cone barrel band, belongs to Machining Technology field,
Background technology
In small-bore cone barrel band, step parts is welded by boring cylinder stamping parts and being with the machine of interior step to add part usually, and small end is sheet metal component, holds greatly as machine adds part.Small end finish dimensional is less, and wall thickness is thinner, and sheet metal component small end oral area can not carry out compression operation, and part outside does not have mounting edge etc. can supply fixing position, and outside need is connected with other parts, can not be blocked by fixture; Owing to holding greatly the internal orifice dimension of interior step to be greater than sheet metal component small end bore, staff can not enter built-in function.Conventional compressing method adopts pressure hook or pressing plate to compress, the rotation of pressure hook and the flexible needs of pressing plate realize by instrument, adjustment difficulty is larger, also need after mixing up to compress one by one (being generally 3 compressions), operate more loaded down with trivial details, and carry out compression operation because instrument will stretch into inside parts, the risk of part of damaging is larger.
Utility model content
For solving the problem, the utility model provides a kind of hold down gag for step parts in small-bore cone barrel band.
The utility model is achieved by following technical solution.
A kind of hold down gag for step parts in small-bore cone barrel band, comprise base plate, screw rod and three-jaw mechanism, described screw rod lower end is connected with base plate by screw thread, described three-jaw mechanism compresses pawl by three and sleeve pipe forms, sleeve pipe is provided with three groups of notches, wherein, three compression pawls 1 are hinged in notch respectively by jointed shaft.
Described three compression pawls are evenly arranged along sleeve pipe for one week.
Described compression pawl lower end is provided with the seal face matched with step surface in part.When compressing pawl and opening, coordinate with step surface in part and realize compressing.
Described compression pawl and hinge axis are matched in clearance.
The beneficial effects of the utility model are:
Adopt hold down gag described in the utility model, first three-jaw mechanism is drawn in when applying and put into part, then En Ya three-jaw mechanism upper end is opened by three-jaw mechanism with finger simultaneously, the seal face of three-jaw mechanism to be placed in part on step surface, again screw rod is threaded connection through sleeve pipe and base plate, screw in screw rod always and make three-jaw mechanism compressing component, thus realize operating the compression of part.Compared with prior art, the utility model is easy and simple to handle, and structure is simple, is convenient to little spatial operation, can in small-bore cone barrel band step parts processing technique field wide popularization and application.

In figure: 1-compresses pawl, 2-hinge axis, 3-sleeve pipe, 4-screw rod, 5-notch, 6-base plate, 7-part.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figures 1 to 4, a kind of hold down gag for step parts in small-bore cone barrel band described in the utility model, comprise base plate 6, screw rod 4 and three-jaw mechanism, described screw rod 4 lower end is connected with base plate 6 by screw thread, described three-jaw mechanism compresses pawl 1 by three and sleeve pipe 3 forms, sleeve pipe 3 is provided with three groups of notches 5, and wherein, three compress pawl 1 and are hinged in notch 5 respectively by jointed shaft 2.Ensureing to compress pawl 1 can flexible rotating.When applying, first three-jaw mechanism is drawn in and put into part 7, then En Ya three-jaw mechanism upper end is opened by three-jaw mechanism with finger simultaneously, the seal face of three-jaw mechanism to be placed in part 7 on step surface, again screw rod 4 is threaded connection through sleeve pipe 3 and base plate 6, screw in screw rod 4 always and make three-jaw mechanism compressing component 7, thus realize operating the compression of part 7.
Described three compression pawls 1 are evenly arranged along sleeve pipe for 3 one weeks.And the angle that every root compresses pawl 1 is 120 °.
Described compression pawl 1 lower end is provided with the seal face matched with step surface in part 7.When compressing pawl 1 and opening, coordinate with step surface in part 7 and realize compressing.
Described compression pawl 1 is matched in clearance with hinge axis 2.To ensure that compressing pawl 1 freely can rotate around hinge axis 2.
As shown in Figure 1, Figure 3, the utility model in use, first compression pawl 1 is drawn in and put into part 7, press pressure compression pawl 1 upper end with finger makes compression pawl 1 open simultaneously, the seal face compressing pawl 1 lower end is placed on the interior step surface of part 7, screw rod 4 is being threaded connection through sleeve pipe 3 and base plate 6, till screw-in screw rod 4 makes compression pawl 1 compressing component 7 always.Simple to operation, be specially adapted to step parts in small-bore cone barrel band that little, the interior step aperture of bore is greater than bore on part and compress.
