Summary of the invention: the purpose of this utility model is the deficiency at above-mentioned technology, and provides a kind of scientific and reasonable for structure, simple to operate laborsaving to people, produces the pneumatic type wheel nut loader of reverse torque phenomenon in the time of avoiding the dismounting lug nut.For achieving the above object, the utility model adopts following technical proposals: the pneumatic type wheel nut loader, comprise framework (12), air motor (1), small belt pulley (2) and big belt pulley (3), it is characterized in that: it also comprises inertia energy storage wheel (4), trundle (5), input dial (6), output dial (7), input shift fork (8), output shift fork (9), input shaft (10), output shaft (11), input shaft (10) is connected with framework (12) by bearing respectively with output shaft (11), and an end of output shaft (11) is contained in the input shaft (10) by bearing carrier ring.Described inertia energy storage wheel (4), can freely rotate on output shaft (11) by bearing installation.Inertia energy storage wheel (4) both sides are equipped with trundle (5), and input dial (6) is connected with input shaft (10) by spline, and can endwisely slip by input shift fork (8).Output dial (7) is connected with output shaft (11) by spline, and can endwisely slip by output shift fork (9).One end of input shift fork (8) is connected with input dial (6); The other end is connected with the piston core bar of cylinder (13).One end of output shift fork (9) is connected with output dial (7); The other end is connected with the piston core bar of cylinder (14).

Structure of the present utility model is the energy storage impact type, and the phenomenon of the reverse torque that has produced when having eliminated existing removing machine dismounting lug nut has realized balance voluntarily.This machine adopts pneumatic mode to drive, and changes impact kinetic energy by size and the energy storage time of adjusting suction quantity, thus the moment of torsion of control dismounting nut.In disassembly process, carry out control by slug relay and timesharing relay countercylinder shift fork, finish actions such as energy storage, clutch conversion, impact, the work of removing machine is carried out according to the mode of anticipation.According to the difference of concrete vehicle, can set suitable parameter and suction quantity realize moment of torsion decide turn round.After setting various parameters, the whole operation process only needs to push the button, and can finish whole disassembly processes.This machine is scientific and reasonable for structure, working stability, simple to operate, easy to maintenance.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

With reference to Fig. 1, the pneumatic type wheel nut loader, comprise framework 12, air motor 1, small belt pulley 2 and big belt pulley 3, it also comprises inertia energy storage wheel 4, trundle 5, input dial 6, output dial 7, input shift fork 8, output shift fork 9, input shaft 10, output shaft 11, input shaft 10 is connected with framework 12 by bearing respectively with output shaft 11, and an end of output shaft 11 is contained in the input shaft 10 by bearing carrier ring.Described inertia energy storage wheel 4, can freely rotate on output shaft 11 by bearing installation.Inertia energy storage is taken turns 4 both sides trundle 5 is installed, and input dial 6 is connected with input shaft 10 by spline, and can endwisely slip by input shift fork 8.Output dial 7 is connected with output shaft 11 by spline, and can endwisely slip by output shift fork 9.One end of input shift fork 8 is connected with input dial 6; The other end is connected with the piston core bar of cylinder 13.One end of output shift fork 9 is connected with output dial 7; The other end is connected with the piston core bar of cylinder 14.

When big belt pulley 3 high speed revolutions, by the air operated control to input shift fork 8, input dial 6 combines with inertia energy storage wheel 4 (stirring trundle 5 by declutch shift shaft), makes inertia energy storage wheel 4 with input shaft 10 rotations, realizes inertia energy storage.During outputting power,, output dial 7 is combined with inertia energy storage wheel 4 (by the pivot pin on the dial and the trundles 5) of rotation, thereby the kinetic energy of inertia energy storage wheel 4 is become the torsional moment of rotating nut by impact by air operated control to output shift fork 9.By output shaft 11 lug nut is screwed or unscrews.When input shaft 10 combined with inertia energy storage wheel 4, output shaft 11 was taken turns 4 separated attitudes with inertia energy storage; When output shaft 11 combined with inertia energy storage wheel 4, input shaft 10 was taken turns 4 separated attitudes with inertia energy storage.By the two combination and hocketing of separating, realize the input of energy and the conversion of output.Wherein the binding time of input shaft and inertia energy storage wheel 4 can be set as required, take turns the rotation function size to regulate inertia energy storage, and output shaft can be set also with the number of times that the inertia energy storage wheel combines according to the torque and the different automobile types of lug nut.After the dismounting of finishing nut, but the closing control power supply.When the connecting times of setting is not finished the dismounting operation of nut, can press the reset key on the control panel, repeat above-mentioned combination and separation process, until finishing disassemble and assemble work.Removing machine is provided with the source of the gas master cock, can regulate the size of suction quantity according to vehicle, controls total suction quantity.

Operating sequence: 1, start-up course: (1) starts Air compressor, makes storage tank pressure rise to 8kg/cm ²(2) total power switch on the connection wheel nut loader control panel; (3) suction quantity is located at suitable gear (heavy goods vehicles is 3 grades, in, Light-duty Vehicle is 2 grades); (4) connect the 24V power supply; (5) connect the 12V power supply.2, reseting procedure:, can press reset key removing machine is worked on, until unclamping nut when deciding to turn round when not unclamping nut in the delay time what set.3, shutdown process: (1) closes the 12V power supply; (2) close the 24V power supply; (3) close the 220V power supply.
