Abstract
The invention relates to a locking device, in particular to a vertical lathe crossbeam locking device. The vertical lathe crossbeam locking device comprises a nut, a belleville spring, an adjusting gasket, a small shaft, a seal ring, a cover, a locking pressure block, a round rod, a case, a rocker and an oil filling port. The belleville spring is mounted on the small shaft and positioned between the nut and the small shaft, the nut is adjusted through the adjusting gasket and then screwed on the case, one end of the small shaft penetrates through holes of the nut and the belleville spring, and the other end of the small shaft is combined with the seal ring and the case to form a seal cavity. The cover is connected with the case, a cylindrical end of the rocker is mounted in a groove of the small shaft, a cam end of the rocker is positioned in the case through a shaft, and the round rod and the locking pressure block are sequentially mounted below the cam. Four locking devices are uniformly distributed at four corners of a crossbeam. The overall dimension and position of a locking structure are modified, and the locking devices are mounted at four corners of the crossbeam respectively, so that displacement of the crossbeam is guaranteed, the crossbeam is in balanced stress, and machining precision is improved.
Description
Technical field
The present invention relates to a kind of locking device, particularly a kind of vertical lathe crossbeam locking device.
Background technology
In vertical lathe, cross beam lock locking oil cylinder structure is a kind of locking mechanism of the most extensive use, and the stressing conditions of this structure has a significant impact the crudy of workpiece.In the prior art, the scheme that single-column lathe cross beam lock locking structure adopts is at single side lock locking oil cylinder piston rod the connecting rod that one end has tooth to be installed, and tooth and the engagement of wedge upper rack are by the flexible purpose that reaches crossbeam locking of oil cylinder.But in this structure, Yi Bian only have the locking device of employing, the monolateral coupling mechanism force of bearing of crossbeam during locking, beam force is uneven, and the crossbeam straightness error strengthens, and affects machining accuracy.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of vertical lathe crossbeam locking device simple in structure, ingenious, rational is provided, this locking device effectively overcomes the unbalanced problem of the beam force that exists in the prior art, thereby improves the crudy of workpiece.
According to technical scheme provided by the invention: a kind of vertical lathe crossbeam locking device, comprise nut, butterfly spring, adjusting pad, little axle, sealing ring, lid, the locking briquetting, round bar, casing and rocking arm, described butterfly spring is installed on the little axle, after described nut is adjusted by adjusting pad, be tightened on the casing, described little axle one end passes the hole of nut and butterfly spring, the other end becomes annular seal space with sealing ring with box body combinations, described lid is connected with casing, described rocking arm cylindrical end is contained in the groove of little axle; the cam end of rocking arm is fixed in the casing by axle, and the cam below is equipped with round bar successively; the locking briquetting; Described round bar is installed between rocking arm and the locking briquetting.
As a further improvement on the present invention, described casing is provided with pouring orifice, and described pouring orifice is communicated with sealing ring, is used for passing into hydraulic oil.
The present invention compared with prior art, advantage is: the present invention passes through the appearance and size of locking mechanism and the improvement of position, locking device is installed respectively at four jiaos of places at crossbeam, overcome in the prior art locking mode to the impact of crossbeam precision, make the beam force balance, reduce the crossbeam straightness error, guaranteed the position degree of crossbeam, thereby improved machining accuracy.In addition, this is simple in structure, ingenious, easy operating.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, comprise nut 1, butterfly spring 2, adjusting pad 3, little axle 4, sealing ring 5, lid 6, locking briquetting 7, round bar 8, casing 9, rocking arm 10, pouring orifice 11.
The present invention adopts butterfly spring 2 to be installed on the little axle 4, after described nut 1 is adjusted by adjusting pad 3, be tightened on the casing 9, described little axle 4 one ends pass the hole of nut 1 and butterfly spring 2, the other end and sealing ring 5 and casing 9 are combined into annular seal space, and described lid 6 is connected connection with casing, and described rocking arm 10 cylindrical ends are contained in the groove of little axle 4; cam end of rocking arm 10 is fixed on the casing 9 by axle, and the cam below is equipped with round bar 8 and locking briquetting 7 successively; Described round bar 8 is installed between rocking arm 10 and the locking briquetting 7.
Described locking briquetting 7 adopts an injecting glue or heap brazing to connect processing technology, has increased frictional force and has made more firmly safety of locking mechanism.Described casing 9 is provided with pouring orifice 11, and described pouring orifice 11 is communicated with sealing ring 5, is used for passing into hydraulic oil.
The present invention makes little axle 4 drive rocking arm 10 and rotates by the distortion elastic force of butterfly spring 2, and the cam of rocking arm 10 presses down, and makes locking briquetting 7 realize locking; Pass into hydraulic oil at pouring orifice 11, little axle 4 moves, compression butterfly spring 2, and locking mechanism unclamps.On four jiaos on lathe crossbeam a locking mechanism is housed respectively, makes the beam force balance, guaranteed the position degree of crossbeam, thereby improved machining accuracy.
