A balance cylinder is fixedly arranged on the cylinder seat, a piston rod connector of the balance cylinder is fixedly connected with an adjusting plate on an adjusting mechanism, and the adjusting mechanism can be locked at set height of the linear shafts. An adapting plate is fixedly connected with the bottom ends of the linear shafts, an adapting part is connected between the adapting plate and a screwing shaft casing, and the screw shaft casing provide with a screwing shaft is hung.
Description
Technical field
The present invention relates to a kind ofly be applied in the automobile main reducer assemble flow, to bearing cap with subtract the suspension type twin shaft tightening machine that the shell connecting bolt is tightened, more specifically say suspension type twin shaft tightening machine stroke regulating mechanism.
Background technology
On the automobile assembling production line to two kinds of the general employings of tightening of bolt: fuselage formula tightening machine and suspension type tightening machine, wherein, fuselage formula tightening machine automaticity is higher, powerful, not only tightens but also can realize other functions.But price is more expensive, suspension type tightening machine low price, easy to operate, take up room little, but for the different model main reducing gear, will be manually adjustment stroke height repeatedly, the suspension type tightening machine that adopts at present, operate all more complicated aspect the adjustment stroke height, and then increasing operator's labour intensity.
Summary of the invention
The present invention is for avoiding the existing deficiency of prior art, a kind of suspension type twin shaft tightening machine stroke regulating mechanism is provided, to simplify the stroke mode, raising labour productivity, improve the quality of products.
The present invention is that the technical solution problem adopts following technical scheme:
The characteristics of suspension type twin shaft tightening machine stroke regulating mechanism of the present invention are: be fixedly installed suspension assembly at suspension supporting frame; Be fixedly installed cylinder block and a pair of vertical axle sleeve that be arranged in parallel that is positioned at the cylinder block both sides at described suspension assembly; The a pair of linear axis that is the parallel longitudinal setting slides in described vertical axle sleeve with the upper end of linear axis; Be fixedly installed balance cylinder at described cylinder block, the piston rod attachment of described balance cylinder is fixedly connected with adjustable plate on the governor motion, and described governor motion can be locked on the setting height of linear axis; Bottom at described linear axis is fixedly connected with keyset, and has adaptor to be connected to described keyset 7 and tighten between the shaft housing, makes to be provided with the shaft housing of tightening of tightening axle and to be suspension.
The characteristics of suspension type twin shaft tightening machine stroke regulating mechanism of the present invention also are: the structure of described governor motion is set to: being set with an excircle at described linear axis is the retaining ring of the conical surface, encapsulation one endoporus is the Locking bushing with same tapering on the outer conical surface of described retaining ring, and the end face diameter of described retaining ring is greater than top, the endoporus hole diameter of Locking bushing; One pressing plate that is sleeved on the linear axis is set at the top of described retaining ring, one mobile pallet 54 that is sleeved on the linear axis is set in the bottom of described Locking bushing, described pressing plate and supporting plate are to be locked vertically by bolt, realize the locking of governor motion on linear axis with the friction that is formed between described retaining ring, Locking bushing and the linear axis.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the stroke control mechanism that consisted of by balance cylinder, linear axis and governor motion of the present invention, but its displacement scope is large and free adjustment, can realize fast, convenient, accurate cylinder stroke adjustment.
2, among the present invention in the governor motion retaining ring and Locking bushing consist of a wedge lock form, its locking mode is simple and reliable, handled easily.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is governor motion structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, the structure shape of the present embodiment centre mounted type twin shaft tightening machine stroke regulating mechanism is:
Be fixedly installed suspension assembly 2 at suspension supporting frame 1; Be fixedly installed cylinder block 3a and a pair of vertical axle sleeve 3b that be arranged in parallel that is positioned at cylinder block 3a both sides at suspension assembly 2; The a pair of linear axis 6 that is the parallel longitudinal setting slides among vertical axle sleeve 3b with the upper end of linear axis 6, and linear axis 6 is as the axis of guide take vertical axle sleeve 3b; Be fixedly installed balance cylinder 4 at cylinder block 3, the piston rod attachment 4a of balance cylinder 4 is fixedly connected with adjustable plate 5a on the governor motion 5, and governor motion 5 can be locked on the setting height of linear axis 6; Be fixedly connected with keyset 7 in the bottom of linear axis 6, and have adaptor 8 to be connected to keyset 7 and tighten between the shaft housing 11, make to be provided with the shaft housing 11 of tightening of tightening axle and to be suspension.
Referring to Fig. 2, the structure of governor motion 5 is set in the present embodiment: being set with an excircle at linear axis 6 is the retaining ring 51 of the conical surface, encapsulation one endoporus is the Locking bushing 52 with same tapering on the outer conical surface of retaining ring 51, and the end face diameter of retaining ring 51 is greater than top, the endoporus hole diameter of Locking bushing 52; One pressing plate 53 that is sleeved on the linear axis 6 is set at the top of retaining ring 51, one mobile pallet 54 that is sleeved on the linear axis 6 is set in the bottom of Locking bushing 52, pressing plate 53 and mobile pallet 54 are to be locked vertically by bolt 55, realize the locking of governor motion 5 on linear axis 6 with the friction that is formed between retaining ring, Locking bushing and the linear axis.
Regulative mode:
Unclamp bolt 55 and namely remove the locking of guiding mechanism, drive governor motion by the piston rod attachment 4a of balance cylinder 4 by adjustable plate 5a and move up and down, when governor motion reached setting height, clamping screw 55 was namely finished adjustment again.
Governor motion in the present embodiment adopts wedge lock, when mobile mobile pallet 54 during along the axis direction free adjustment of linear axis 6 to correct position, tight a bolt 5 by pressing plate 53 compression retaining rings 51, so that between retaining ring, Locking bushing and linear axis, produce stiction, thereby be locked on the desired location, but the large free adjustment of this version displacement scope, novel structure, handled easily worker operation.
