Abstract
The utility model relates to a hold-down mechanism of a pneumatic motor that is used for a pneumatic wrench. The pneumatic wrench comprises a rear shell and a front shell, wherein, a pneumatic motor that consists of an air cylinder, a rotor and blades is arranged inside the rear shell; both ends of the air cylinder are respectively provided with a front end plate and a rear end plate; the front end plate is provided with a spring disc; the pneumatic motor is connected with a striking shaft; a striking block is arranged outside the striking shaft; an impact cylinder is arranged outside the striking block; the impact cylinder is arranged inside the front shell; one end of the rear shell is provided with an insertion groove, and one end of the front shell is provided with a bulge loop; the bulge loop is connected with the end surface of the rear shell through a tightening element. The pneumatic wrench is characterized in that a collision nozzle is arranged inside the bulge loop, and the collision nozzle is inserted into the insertion groove to be contacted with the spring disc. The collision nozzle is directly arranged on the front shell to be contacted with the spring disc, and compared with the prior art adopting the single lining to compress, the integrated pneumatic wrench has simple structure, and is convenient to be processed and to be assembled, and is easy to guarantee the processing precision, and has low cost, and can shorten the production period.
Description
Technical field
The utility model relates to the hold-down mechanism of pneumatic wrench usefulness gas motor, belongs to pneumatic tool.
Background technology
Pneumatic wrench is a kind of pneumatic screw thread erecting tools, be mainly used in the loading and unloading threaded fastener, can improve the efficiency of loading and unloading of threaded fastener, alleviate assembling labour intensity, guarantee the assembly quality of finished product, on the modernized assembling line of industry such as aircraft, guided missile, locomotive, automobile, tractor, electronic apparatus, all extensively adopt at present.Pneumatic wrench is made up of power section and beat component, and power section mainly comprises the gas motor, and the gas motor comprises cylinder, rotor and blade, and the cylinder two ends are equipped with front end-plate and end plate respectively, and the gas motor is through being bolted in the back casing; Beat component is formed by hitting axle, taping block, impact tube etc., and beat component is fixed in the procapsid.In order to compress the gas motor, guarantee the sealing of gas motor, beat component is rotated at a high speed, mounting spring video disc outside the front end-plate of cylinder, the spring video disc relies on lining and procapsid to compress, but because lining and procapsid are two independently parts, lining is a thin-wall part, higher and the modified back easy deformation of processing cost, and form and position tolerance is difficult to guarantee.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of cost low, with short production cycle, and easy to process, is easy to guarantee the hold-down mechanism of the pneumatic wrench usefulness gas motor of machining accuracy.
The technical scheme of the hold-down mechanism of the utility model pneumatic wrench usefulness gas motor is: pneumatic wrench comprises back casing and procapsid, be equipped with in the back casing by cylinder, the gas motor that rotor and blade are formed, the cylinder two ends are equipped with front end-plate and end plate respectively, front end-plate is equipped with the spring video disc outward, the gas motor connects the strike axle, hit the outer taping block that is equipped with of axle, taping block is equipped with outward and impacts tube, impacting tube is installed in the procapsid, one of back casing is shaped on slot, and one of procapsid is shaped on bulge loop, and bulge loop is connected with the end face of back casing through securing member, it is characterized in that being shaped in the bulge loop and bump mouth, bump mouth and insert in the slot and contact with the spring video disc.
The hold-down mechanism of pneumatic wrench usefulness gas motor of the present utility model, directly system is bumped mouth and is contacted with the spring video disc on procapsid, adopting independent lining to compress with prior art compares, after making one, simple in structure, processing, easy to assembly is easy to guarantee machining accuracy, cost is low, and can shorten the production cycle.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model pneumatic wrench;
The hold-down mechanism structural representation of the pneumatic wrench usefulness gas motor that Fig. 2 is;
Fig. 3 is the structural representation that prior art adopts lining to compress.
The specific embodiment
The utility model discloses a kind of hold-down mechanism of pneumatic wrench usefulness gas motor, as Fig. 1, shown in Figure 2, pneumatic wrench comprises back casing 1 and procapsid 2, be equipped with in the back casing 1 by cylinder 3, the gas motor that rotor 4 and blade 5 are formed, the cylinder two ends are equipped with front end-plate 6 and end plate 7 respectively, the front end-plate 6 outer spring video discs 8 that are equipped with, the rotor 4 of gas motor is connected with strike axle 9 by spline, hit the axle 9 outer taping blocks 10 that are equipped with, taping block 10 outer being equipped with are impacted tube 11, impacting tube 11 is installed in the procapsid 2, one of back casing 1 is shaped on slot 18, and one of procapsid 2 is shaped on bulge loop 28, and bulge loop 28 is connected with the end face of back casing through securing member, it is characterized in that being shaped in the bulge loop 28 and bump mouth 29, bump mouth 29 and insert in the slots 18 and contact with spring video disc 8.This programme directly on procapsid 2 system bump mouth 29 and contact with spring video disc 8, adopt independent lining 20 (as shown in Figure 3 with prior art, spring video disc 8 relies on lining 20 to compress with procapsid) compress and compare, after making one, simple in structure, processing, easy to assembly, cost is low, and can shorten the production cycle.The course of work of pneumatic wrench is as follows: compressed air enters the gas motor through back casing 1, and to hitting axle 9, the square head 91 of hitting axle cooperates with sleeve the rotor 4 of gas motor with transmission of power, by the sleeve threaded fastener of tightening or relax.The beat component of pneumatic wrench can adopt two hammer impact structures, can convert the revolution of gas motor to the revolution ballistic work, and securing member is tightened or dismantled to the revolution impact moment.Compare with the quiet formula of turning round, the revolution impact structure can amplify tens times with the motor output torque, even hundred times.
