Abstract
The utility model discloses a lateral-expansion pressing device, which comprises an aluminum tank, a steel wedge and a bolt. The steel wedge is arranged in the middle of the aluminum tank and is connected with the aluminum tank through the bolt. Clamping parts are arranged at the two ends of the aluminum tank. An elastic part is arranged in the middle of the aluminum tank. Inclined surfaces corresponding to the steel wedge are arranged on the internal sides of the clamping parts. The steel wedge is arranged between the clamping parts and is in contact with the clamping parts. By screwing or unscrewing the bolt to drive the steel wedge, the tightness of the aluminum tank is adjusted. The lateral-expansion pressing device provided by the utility model is an elastic fixture and the tightness of the aluminum tank is adjusted under cooperation of the bolt and the steel wedge to realize clamping. Large-size workpieces can be clamped under cooperation of a plurality of lateral-expansion pressing devices. Since aluminum materials are used to be in contact with the workpieces, the surfaces of the workpieces are enabled not to be damaged easily.
Description
Technical field
The utility model relates to a kind of fixture, in particular to a kind of lateral expansion hold down gag.
Background technology
In universal fixturing, bench vice is used more extensive.But for the clamping of large-scale workpiece, clamping inconvenience of bench vice.On the other hand, after the bench vice clamping, surface of the work is easily destroyed, affects workpiece surface quality.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of lateral expansion hold down gag is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of lateral expansion hold down gag, comprise aluminium groove, gad and bolt, described gad is arranged in the middle of described aluminium groove, be connected by described bolt, described aluminium groove two ends are clamping section, and the centre is elastic portion, and described clamping section inboard is provided with the inclined-plane corresponding with described gad, described gad is placed between described clamping section, and contacts; Screw-in or back-out by described bolt drive described gad, thereby adjust the tensioning of described aluminium groove.
The beneficial effects of the utility model are:
Lateral expansion hold down gag of the present utility model is a kind of spring chuck, by the coordinate tensioning of adjusting aluminium groove of bolt with gad, realizes clamping.The clamping that can be used for large-scale workpiece by the cooperation of a plurality of lateral expansion hold down gags.Used aluminium to contact with workpiece, made surface of the work not fragile.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
