Abstract
The invention discloses a locking mechanism on a linear shaft. The locking mechanism is characterized in that a locking ring of which the outer circumference is a conical surface is sleeved on the linear shaft, a locking bush of which the inner hole has the same taper is sleeved on the external conical surface of the locking ring, and the diameter of the top surface of the locking ring is larger than the diameter of the top of the inner hole of the locking bush; and the top of the locking ring is provided with a press plate sleeved on the linear shaft, the bottom of the locking bush is provided with a moving support plate sleeved on the linear shaft, and the press plate and the support plate are axially locked by bolts to form friction force among the locking ring, the locking bush and the linear shaft so as to realize the locking of the locking mechanism on the linear shaft. According to the locking mechanism, the locking ring and the locking bush are in a wedge-shaped locking mode, and the locking mode is simple and reliable so as to facilitate operation.
Description
Technical field
The present invention relates to a kind of locking mechanism, more specifically say the locking mechanism that is applied on the linear axis.
Background technique
Need to carry out positioning and locking at linear axis under a lot of occasions in the industrial production, and its locked position can be adjusted arbitrarily as required.But, do not have in the prior art a kind of adjustment mode simple, locate reliable locking mechanism.
Summary of the invention
The present invention is for avoiding the existing deficiency of prior art, provides that a kind of adjustment mode is simple, locking mechanism on the reliable linear axis in location, to raise labour productivity, to improve the quality of products.
The present invention is that the technical solution problem adopts following technological scheme:
The characteristics of locking mechanism are on the linear axis of the present invention: being set with an excircle at linear axis is the locking ring of the conical surface, encapsulation one endoporus is the Locking bushing with same tapering on the outer conical surface of described locking ring, and the end face diameter of described locking 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 locking ring, one mobile pallet 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 locking mechanism on linear axis with the friction that is formed between described locking ring, Locking bushing and the linear axis.
Compared with the prior art, beneficial effect of the present invention is embodied in: locking ring and Locking bushing consist of a wedge lock form among the present invention, and its locking mode is simple and reliable, easy-to-operat.
Description of drawings
Fig. 1 is the concrete application structure schematic diagram of locking mechanism of the present invention;
Fig. 2 is locking mechanism structure schematic diagram of the present invention.
Embodiment
Referring to Fig. 2, locking mechanism is to be the locking ring 51 of the conical surface at linear axis 6 suit one excircle on the present embodiment cathetus axle, encapsulation one endoporus is the Locking bushing 52 with same tapering on the outer conical surface of locking ring 51, and the end face diameter of locking 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 locking 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 supporting plate 54 are to be locked vertically by bolt 55, realize the locking of locking mechanism on linear axis 6 with the friction that is formed between locking ring, Locking bushing and the linear axis.
Figure 1 shows that the present embodiment is applied to suspension type twin shaft tightening machine stroke regulating mechanism:
Referring to Fig. 1, 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 regulator plate 5a on the controlling mechanism 5, controlling mechanism 5 is locking mechanism on the linear axis shown in Figure 2 in the present embodiment, can be locked on the setting height of linear axis 6; Be fixedly connected with pinboard 7 in the bottom of linear axis 6, and have adaptor 8 to be connected to pinboard 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.
Regulative mode:
Unclamp bolt 55 and namely remove the locking of regulating mechanism, drive controlling mechanism by the piston rod attachment 4a of balance cylinder 4 by regulator plate 5a and move up and down, when controlling mechanism reached setting height, lock bolt 55 was namely finished adjustment again.
