Abstract
The utility model provides a positioning fixture for piston rod heads. The positioning fixture comprises a processing base, wherein a positioning cavity matched with the shape of a to-be-processed workpiece is arranged in the processing base; the lower end of the processing base is provided with a stepped substrate; and one end of the positioning cavity is positioned above the substrate, and the other end of the positioning cavity extends out of the substrate. After the positioning fixture adopts the scheme, the fixture is put on a machine tool at first, the substrate is fixed through a pressing plate and a bolt, then the workpiece is put in the positioning cavity, and finally the workpiece can be processed. The positioning fixture has the advantages of simple structure, convenience in operation and low labor strength of workers.
Description
Technical field
The utility model relates to the oil cylinder processing technique field, refers in particular to a kind of positioning fixture that is used for piston rod head.
Background technology
Oil cylinder is a hydraulic cylinder, and hydraulic cylinder is the linear motion type executive component that the pressure reduction on power output and piston effective area and both sides thereof is directly proportional.Its function is can convert hydraulic pressure to mechanical energy.The input quantity of hydraulic cylinder is the flow and the pressure of fluid, output be point-to-point speed and power.The piston of hydraulic cylinder can be finished straight reciprocating motion, and the straight-line displacement of output is limited.Hydraulic cylinder is the energy conversion device that hydraulic pressure can be converted to the mechanical energy of linear reciprocating motion.Oil cylinder is mainly used in needs the long-time place of supporting weight, and it can still can support weight when removing oil pressure, and safe and reliable.Can be used under water single-acting, load retraction; the nut self-locking makes load safer, in heavy construction, is easy operation control and self-locking jack especially; design has safe pressurizer, built-in pressure-relief valve to prevent overload, is beneficial to safety operation with protection self-locking jack.The connection of this device, what adopt is that high-pressure rubber pipe is connected with nipple, have and use fast, and overcome the equipment installation top lifting field-strip that quick traditional jointing leakage of oil shortcoming is mainly used in multiple industries such as electric power, building, machine-building, mine, railroad bridge, shipbuilding.Piston rod head is as one of essential elements of oil cylinder, its processing request is higher, especially require level and smooth in the side of car bar head, be directly to be fixed on the lathe now mostly with pressing plate, because the bar head belongs to profiled piece, it is bad operation fixedly the time, in case adding bar head skew in man-hour, the situation that will cause the bar head to scrap.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, positioning fixture of being exclusively used in the fixed piston rod head is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of positioning fixture that is used for piston rod head, it includes the processing seat, processing seat is provided with a positioning chamber that is complementary with the processing work shape, processing seat lower end is provided with the stairstepping pedestal, positioning chamber one end is positioned at the pedestal top, and the other end extends to outside the pedestal.
Described pedestal is an annular.
Described processing seat is fixed on the pedestal by screw rod.
The utility model is put anchor clamps to lathe earlier after having adopted such scheme, by pressing plate and bolt pedestal is fixed, and workpiece is put into positioning chamber again and can be processed.This programme simple in structure, easy to operate, labor strength is low.
Description of drawings
Fig. 1 is a clamp structure schematic diagram of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the schematic diagram of the utility model processing work.
The specific embodiment
The utility model is described in further detail below in conjunction with institute's drawings attached, preferred embodiment of the present utility model is: referring to accompanying drawing 1 to accompanying drawing 3, the described positioning fixture that is used for piston rod head of present embodiment includes processing seat 1, processing seat 1 is provided with a positioning chamber 2 that is complementary with the processing work shape, processing seat 1 lower end is provided with stairstepping pedestal 3, and positioning chamber 2 one ends are positioned at pedestal 3 tops, and the other end extends to outside the pedestal 3, because the bar head is to belong to shaped piece, its irregular end is unsettled outside pedestal.The pedestal 3 of present embodiment is an annular, certainly, also can adopt other shape according to lathe characteristics or actual needs, and as square or polygon, processing seat 1 is fixed on the pedestal 3 by screw rod.Earlier anchor clamps are put to lathe, pedestal is fixed, again workpiece is put into positioning chamber by pressing plate and bolt.Because the positioning chamber shape is consistent with the bar head shapes, so phenomenons such as skew can not take place adding man-hour bar head.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
