Description

A kind of fixture of quick-replaceable ringfeder
Technical field
The utility model relates to frock clamp fields, and in particular to a kind of fixture of quick-replaceable ringfeder.
Background technique
With the development of science and technology industrial processes category greatly increases and steps into the production method of discrete type, therefore, work The compatibility and replacement convenience of clamps are a very critical index.Ringfeder clamping is very widely used and mature A kind of clamp form, ringfeder clamping be mainly made of connecting shaft, ringfeder and pull rod three parts, for Internal hole positioning Workpiece has good adaptability.But due to being limited by ringfeder physical property itself, for the compatibility of inner hole specification Not strong, but inner hole difference biggish workpiece similar to shape must replace ringfeder specification.Therefore, multi items discrete type is processed Production line, the convenience and efficiency of ringfeder replacement influence processing efficiency very big.
Traditional expansion sleeve fixture should first unscrew pull rod when replacing fixture, remove pull rod and ringfeder, be then changed to phase Pull rod loading is screwed again after answering the ringfeder of specification.Since fit-up gap is small between pull rod, connecting shaft, workpiece location hole, cooperation Stroke is long, and ringfeder is time-consuming and laborious when removing and being packed into, and has seriously affected the efficiency of ringfeder replacement.
Summary of the invention
The technical problems to be solved in the utility model is how to overcome the shortcomings of the prior art, provides one kind quickly more Change the fixture of ringfeder.
The technical solution of the utility model is: a kind of fixture of quick-replaceable ringfeder, including connecting shaft, pull rod and rises Set, the connecting shaft are integrally formed, and top is up-narrow and down-wide rotary table portion, and lower part is cylindrical portion, rotary table portion bottom radius Less than the cylindrical portion radius, the cylindrical portion top edge is provided with circular trough;The pull rod includes the cylinder being fixedly connected Head, neck and main part, the head is identical with main part radius, half neck of neck be less than the head and main part Radius, the top of the main part is circumferentially fixed to be equipped with horizontal ledge;The connecting shaft is provided with centre bore, the pull rod main body The horizontal ledge in portion is sleeved and fixed in the connecting shaft center hole with lower section;The ringfeder is the cup body shape of back-off, described to rise Set bottom is fastened in the circular trough at the top of the connecting shaft cylindrical portion, and aperture, the pull rod are equipped at the top of the ringfeder Main part passes through the aperture, is fastened in the horizontal ledge on the main part top at the top of the ringfeder, the ringfeder Side inner surface lower part and the outer surface in connecting shaft rotary table portion fit, the ringfeder side exterior surface and workpiece location hole Surface fits;The pull rod neck is also cased with annular gasket, and the annular gasket is by identical two semi-circular shape pads Piece composition, the annular gasket lower surface is pressed together at the top of the pull rod main part and the ringfeder top surface, the drawing Ring-shaped cylinder cutting ferrule is nested and fixed on the outside of club head, the ring-shaped cylinder cutting ferrule is pressed together on the annular gasket upper surface.
Further, the rod head is sleeved and fixed with the ring-shaped cylinder cutting ferrule with holding screw.
Further, it is equipped with annular protrusion on the inside of the annular gasket, the ring-shaped cylinder cutting ferrule is pressed together on the ring On the annular gasket upper surface in shape protrusion outside.
The clamp structure of the utility model designs simple, clever structure, in ringfeder when removing, without removing pull rod, only Pull rod need to be loosened, unscrew holding screw, remove ring-shaped cylinder cutting ferrule, remove semi-circular shape gasket, ringfeder can take out from top. When ringfeder assembles, selects the corresponding ringfeder of workpiece to be put into corresponding position, load onto two semi-circular shape gaskets, make pull rod and two Semi-circular shape gasket closely presses, and is put into ring-shaped cylinder cutting ferrule, screws holding screw, and ringfeder assembly can be completed.Operating process Simply, the time is saved, is improved efficiency.The utility model is worth with market potential.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is a kind of fixture cut-away view of quick-replaceable ringfeder disclosed by the utility model;
Fig. 2 is a kind of fixture semi-circular shape gasket schematic diagram of quick-replaceable ringfeder disclosed by the utility model.
Specific embodiment
Referring to the drawings and embodiment, a kind of fixture of quick-replaceable ringfeder of the utility model is described in detail.
As shown in Figure 1, 2, a kind of fixture of quick-replaceable ringfeder, including connecting shaft, pull rod and ringfeder 3, the connecting shaft It is integrally formed, top is up-narrow and down-wide rotary table portion 11, and lower part is cylindrical portion 12, and 11 bottom radius of rotary table portion is less than described 12 radius of cylindrical portion, 12 top edge of cylindrical portion are provided with circular trough 121;The pull rod includes the cylinder being fixedly connected Head 21, neck 22 and main part 23, the head 21 is identical with 23 radius of main part, and 22 half neck of neck is less than the head 23 radius of portion 21 and main part, the top of the main part 23 is circumferentially fixed to be equipped with horizontal ledge 231;The connecting shaft is provided with The horizontal ledge 231 of centre bore 13, the pull rod main part 23 is sleeved and fixed in the connecting shaft center hole 13 with lower section;Institute The cup body shape that ringfeder 3 is back-off is stated, 3 bottom of ringfeder is fastened in the circular trough 121 at 12 top of connecting shaft cylindrical portion, Aperture 31 is equipped at the top of the ringfeder 3, the pull rod main part 23 passes through the aperture 31, is fastened on institute at the top of the ringfeder 3 In the horizontal ledge 231 for stating 23 top of main part, 3 side inner surface of ringfeder, 32 lower part and connecting shaft rotary table portion 11 Outer surface fits, and 3 side exterior surface 33 of ringfeder fits with 4 surface of workpiece location hole;The pull rod neck 22 also covers There is annular gasket 5, the annular gasket 5 is made of identical two semi-circular shape gaskets 51, under the annular gasket 5 Surface is pressed together on 23 top of pull rod main part and 3 top surface of ringfeder, is sleeved and fixed on the outside of the rod head 21 There is ring-shaped cylinder cutting ferrule 6, the ring-shaped cylinder cutting ferrule 6 is pressed together on 5 upper surface of annular gasket.
