Abstract

The utility model relates to a resultant pneumatic riveter. A pipe mouth of an intake valve with high pressure and a muffler are arranged at a cylindrical main body (I) which is fixed to a base seat, and the intake valve is used as a motive power. A key and an oil feeding hole are arranged on a main body (II), and the key is utilized to control a both-way pneumatic motor to rotate. The upper part of the main body (II) is supported with a both-way pneumatic motor assembly. The utility model has the advantages of flexible operation, reliable performance, convenient carryover, simple structure, and light and small volume; in addition, the utility model can be conveniently operated at a place which is difficult to contact.

Description

The pneumatic rivet puller of making a concerted effort

The utility model belongs to the metalworking machinery field of tool, specially refers to a kind of pneumatic rivet puller of making a concerted effort.

At present, the appearing in the newspapers of existing on the market pneumatic rivet puller led more, for example: Chinese patent 96224130.X " pneumatic type hand riveter ", the applicant successively discloses features simple structure, well behaved staking instrument, have better performance and rational structure more than disclosed patent 92218163 " pneumatic riveting nut staking machine " more in early time, the unfavoured state of screw thread dynamic stress when having overcome riveting nut in the past, thereby improved the instrument abrasion resistance, increased service life, this development has embodied the continuous progress and the renewal of science and technology, yet, in some occasion that need rivet, especially work and be difficult to move or take off the occasion of riveting, just wish to have a kind of portable light more little clincher tool, it can be operated the everywhere neatly and be difficult for mobile riveting parts, wishes that its construction weight is light and handy as far as possible, and operation is convenient.

The purpose of this utility model, be for overcome existing pneumatic riveting instrument weight, volume is all bigger, structure is easy inadequately, operation lacks weak points such as nimble property, and wish to design small and exquisite pneumatic rivet puller gently little, portable, simple in structure, and wish its flexible operation, long service life.

The utility model relies on following technical proposals to realize, a kind of pneumatic rivet puller of making a concerted effort, mainly include a main body base Cuo, air motor, the spring reset hydraulic cylinder, the plunger type auxiliary oil cylinder, master cylinder, flat valve and the staking screw rod that is driven, it is characterized in that, be fixed on the garden columnar body (I) of basic Cuo, be provided with the air intake valve mouth of pipe and silencer as the high pressure gas of power, main body (I) upper end is fixed with main body (II), this main body (II) is provided with the button and the oil filler point of control two-way pneumatic motor rotation, the two-way pneumatic motor sub-assembly is being supported in the top of main body (II), the rear end of this assembly is provided with the plunger type auxiliary oil cylinder and is socketed with protective cover, and front end is connected with locking nut and by its locking, the staking screw rod of replaceable size model.

The control button that aforementioned body is set, it is for making wind motor just change and rivet the two-way rotation button of these the two kinds of actions of counter-rotating when withdrawing from screw rod after finishing, and the eyelet on the main body is the special-purpose eyelet of injection lubricating oil.

Above-mentioned wind motor assembly, mainly comprise vertically feeler lever, the coupled connection swivel nut that is connected together arranged, be sleeved on the planet carrier that has the planet tooth on the planet carrier drive tab, continue to be connected to successively rotor bearing and cylinder, be placed in the cylinder centre rotor coaxial, cylinder constitutes a closed state together with bonnet, being close to device has holddown spring, is thereafter the locking nut of plastics silencer and afterbody.

The good effect of this programme is, has the staking flexible operation, dependable performance, easy to carry, and the place that is difficult for reaching also can easily be operated, and is simple in structure, volume is gently little.

Further specify embodiment below in conjunction with accompanying drawing:

Description of drawings:

Fig. 1 is a portable pneumatic staking machine agent structure schematic diagram;

Fig. 2 is an air motor assembly annexation schematic diagram;

Fig. 1 is this device sheath, 2 is base, the base upper support garden columnar body (I) 3, its sidewall is provided with two tube passages, its valve mouth of pipe 4 and silencer 5 are for feeding compressed air and compressed liquid respectively as power resources, 6 is main body (II), be supported on the top of main body (I), its the place ahead is provided with two-way rotation button 7, sidewall is provided with the eyelet 8 of oil-feed, the protective cover 9 at wind motor assembly 11 and rear thereof is being supported in the main body top, is the handle that is provided with 10 easy to carry, and wind motor assembly end is the staking screw rod 13 of locking nut 12 and replaceable size model.

Wherein the wind motor assembly 11, it mainly comprises the feeler lever of arranging vertically 11.1, coupled connection swivel nut 11.2, planet carrier bearing 11.3, have the planet tooth internal gear 11.5 of planet carrier 11.4 devices of planet tooth in the planet carrier outside, what continue edge axle arrangement is rotor bearing 11.6, cylinder protecgulum 11.7, rotor 11.8, cylinder 11.9 and cylinder back cover 11.10, after be connected to spring 11.11, plastics silencer 11.12 is afterbody locking nut 11.13 at last.

When specified air-flow inserts this machine, it just enters duty by the instruction operation.On the working head pull bar of riveting spiral shell spare spiral shell end by this machine of being placed on, press pull bar, make the valve contact pilotage start wind motor dextrorotation valve, pull bar dextrorotation, install riveting spiral shell spare, riveting spiral shell spare is inserted accomplish fluently in the workpiece in pre-hole then, press staking job instruction button again, high pressure draught enters master cylinder through flat valve, cylinder piston starts, and cylinder piston is pressed into hydraulic cylinder to hydraulic oil simultaneously as the auxiliary oil cylinder plunger, the driving hydraulic piston retreats, and drive pull bar riveting spiral shell spare riveted on workpiece, decontrol staking operation button, piston resets under spring action, press wind motor dextrorotation button pull bar again and withdraw from riveting spiral shell spare, the staking operation is finished.
