Description
Technical field
The utility model belongs to plastic products manufacture field.
Background technology
From the eighties of last century plastic products seventies in industry and life large-scale application, plastic products to become in petroleum chemical industry an important branch, are used in a lot of application.Plastic bolt, also known as plastic bolt, plastic bolt is compared common metal bolt, has insulation, without high-quality characteristics such as magnetic, corrosion-resistant, attractive in appearance, Never-rusties, its application also widely.In addition because nonmetal manufacture, can not produce the signal disturbing such as eddy current under electric current or the impact of other signals of telecommunication, it is jamproof is suitable for a little the industries such as communication.
Existing plastic bolt is after being injection molded into base substrate, first to carry out burr process to base substrate, due to plastic bolt small volume, existing burr process is all that the hand-held burr file of workman picks burr to plastic bolt, if then adopt general bolt fixture, due to plastics hardness and do not go up metal, general fixture is easy to plastic bolt to be clamped to distortion or bending because grip force is excessive.
Utility model content
The utility model is intended to provide a kind of and improves burr treatment effeciency and can not damage the fixture of plastic bolt.
Plastic bolt fixture in this programme, comprise cylinder, cylinder block has the first air ports, cylinder tail end has the second air ports, piston is provided with in cylinder, the piston rod be connected with piston stretches out cylinder front end, spring is provided with between piston and cylinder tail end, the front end of cylinder is connected with erecting bed, this erecting bed has chute, and be furnished with and interconnective slide block coaxial with piston rod in chute, the front end of this slide block is hinged with pair of links, both sides, erecting bed front end are all hinged with jaw, jaw also with the rod hinge connection of homonymy; Have arc groove at jaw leading inside, jaw is fixed with the fender rod of linear arc-shaped groove center point, the distance between fender rod front end and arc groove lowest part is the nut radius of plastic bolt.
The beneficial effects of the utility model are: drive to slide by the piston rod of cylinder and move in chute, jaw open and close is made by connecting rod, due to jaw being fixed with fender rod, and the distance between this fender rod front end and pawl grip hold arc connected in star lowest part is the nut radius of plastic bolt, make jaw when the nut of closed clamping plastic bolt, fender rod contacts with the threaded shank of plastic bolt, can prevent jaw grip force from excessively causing plastic bolt to be out of shape, appearance of bending or other damages.The utility model structure is simple, can improve the burr treatment effeciency of plastic bolt and can protect plastic bolt.
Further, the tail end of described jaw is corner block, corner block one end and rod hinge connection, the other end and erecting bed hinged, rotate more steady.
Further, described erecting bed extends to form clamping part towards jaw front end, and clamping part has arc groove on the position corresponding with homonymy jaw, can reduce the rotational angle of jaw by arranging clamping part, thus reduces the stroke of cylinder.
Further, cylinder front end and erecting bed are bolted to connection, and connect more firm.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the utility model plastic bolt fixture embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: cylinder 1, erecting bed 2, first air ports 3, second air ports 4, spring 5, piston rod 6, slide block 7, connecting rod 8, corner block 9, jaw 10, fender rod 11, clamping part 12.
Embodiment is substantially as shown in Figure 1: plastic bolt fixture, comprise cylinder 1 and erecting bed 2, the cylinder body of cylinder 1 is provided with the first air ports, the tail end of cylinder 1 has the second air ports, piston is sliding combined with in cylinder 1, be provided with spring 5 between piston and cylinder 1 tail end, piston be fixed with piston rod 6, this piston rod 6 stretches out from the front end of cylinder 1.
The front end of cylinder 1 is bolted erecting bed 2, this erecting bed 2 has chute, is combined with slide block 7 in chute, and this pulley is coaxial with piston rod 6 and be fixedly connected with by rivet, and slide block 7 front end is hinged with the connecting rod 8 of a pair specular.There is the jaw 10 of a pair specular the front end of this erecting bed 2, and the tail end of this jaw 10 is corner block 9, and side and the erecting bed 2 of each corner block 9 are hinged, and opposite side is hinged with connecting rod 8 free end near it.Piston rod 6 moves with slide block 7, thus connecting rod 8 is rotated with corner block 9, and the rotation of corner block 9 makes jaw 10 close and open.
The arc groove that jaw 10 front end has, erecting bed 2 extends to form clamping part 12 towards jaw 10 front end, the position that this clamping part 12 is corresponding with homonymy jaw 10 has arc groove, two jaws 10 close, arc groove and the clamping part 12 homonymy arc groove of each jaw 10 are combined to form the nut clamping hole clamping plastic bolt, position near arc groove on jaw 10 has been bolted fender rod 11, this fender rod 11 points to the central point of arc groove, fender rod 11 front end is the arc coordinated with the threaded shank of plastic bolt, distance between this fender rod 11 front end and arc groove lowest part is the nut radius of plastic bolt.
The course of work of the present embodiment is: Compressed Gas enters from the first air ports, second air ports exhaust, piston and piston rod 6 are moved to left, slide block 7 moves to left in chute, slide block 7 makes connecting rod 8 drive corner block 9 to rotate, thus jaw 10 is rotated towards clamping part 12, thus the nut of grip plastic bolt, and the fender rod 11 on jaw 10 props up the threaded shank of plastic bolt, prevent jaw 10 from pressing from both sides bad plastic bolt.After Compressed Gas stopping passes into, piston homing under the promotion of spring 5, in like manner, jaw 10 also unclamps and carries out discharging.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect the effect of the utility model enforcement and the practicality of utility model.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
