Abstract
The invention relates to a hydraulic locking structure for a numerical control milling and drilling machine. A locking cylinder is fixedly arranged at one end part of a jaw body, the other end of the jaw body is provided with a locking strip, a jaw bridge plate is hinged on the jaw body arranged between the locking cylinder and the locking strip, a piston rod on the locking cylinder is fixedly provided with a wedge plate, the wedge plate is inserted between one end part of the jaw bridge plate and the jaw body, the other end part of the jaw bridge plate is arranged on the locking strip; and the jaw body is provided with a resetting mechanism for the jaw bridge plate. The hydraulic locking structure provided by the invention has a simple structure and runs steadily and reliably. By adopting the structure provided by the invention, the defect that a workpiece vibrates when being drilled and milled can be overcome when the cylinder is started; and a hydraulic system is adopted to controlcompacting and loosening of the cylinder, thus being more practical and more efficient and saving more time and labour, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of use and on the numerical control drilling milling machine, can realize and the locking of direction of feed and the device of location horizontal, vertical to spindle drum, especially a kind of hydraulic locking mechanism of numerical control drilling milling machine.
Background technology
Have in the technology at oneself, the auto-lock function of servomotor is often adopted in the locking of main shaft and location.But because workpiece can produce larger vibrations when milling, the auto-lock function of servomotor can not guarantee fast, effectively, accurately that main shaft is not moved, and is not suitable for the requirement of enterprise's processing when processing work.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the hydraulic locking mechanism of a kind of easy to operate, dependable performance, practical numerical control drilling milling machine is provided.
According to technical scheme provided by the invention, the hydraulic locking mechanism of described numerical control drilling milling machine, an end that is included in the jaw body is installed with locking cylinder, the other end at the jaw body is equipped with locking strip, jaw body between locking cylinder and locking strip is hinged with the jaw bridge plate, be installed with at the piston rod of locking cylinder and tiltedly carve plate, the described plate of tiltedly carving inserts between the end and jaw body of jaw bridge plate, and the other end of jaw bridge plate is positioned on the locking strip; Be provided with the resetting-mechanism of jaw bridge plate at the jaw body.
Jaw body at locking strip one end offers the back-moving spring hole, in the back-moving spring hole back-moving spring is installed, and is provided with holding screw in the bottom in back-moving spring hole, and the jaw bridge plate of described back-moving spring and locking strip one end offsets.
The middle part of described jaw bridge plate has the lug boss of rib shape, and the both ends of jaw bridge plate have the planar lug boss of cylinder.
The present invention is simple in structure, operate steadily, reliably.Structure of the present invention can effectively guarantee to solve the phenomenon that shake occurs workpiece when brill mills when starting oil cylinder; Adopt hydraulic system to control the compression of oil cylinder and unclamp, more practical, effective, save time, laborsaving, improved production efficiency.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly by locking strip 1, jaw bridge plate 2, jaw bearing pin 3, tiltedly carve the parts such as plate 4, round nut 5, oil cylinder 6, jaw body 7, locking spring 8, holding screw 9 and back-moving spring hole 10 and consist of.
The hydraulic locking mechanism of this numerical control drilling milling machine, be included in the hard-wired locking cylinder 6 in an end of jaw body 7, the other end at jaw body 7 is equipped with locking strip 1, jaw body 7 between locking cylinder 6 and locking strip 1 is hinged with jaw bridge plate 2, be installed with at the piston rod of locking cylinder 6 and tiltedly carve plate 4, the described plate 4 of tiltedly carving inserts between the end and jaw body 7 of jaw bridge plate 2, and the other end of jaw bridge plate 2 is positioned on the locking strip 1; Be provided with the resetting-mechanism of jaw bridge plate 2 at jaw body 7.
Jaw body 7 at locking strip 1 one ends offers back-moving spring hole 10, and back-moving spring 8 is installed in back-moving spring hole 10, is provided with holding screw 9 in the bottom in back-moving spring hole 10, and described back-moving spring 8 offsets with the jaw bridge plate 2 of locking strip 1 one ends.
The middle part of described jaw bridge plate 2 has the lug boss of rib shape, and the both ends of jaw bridge plate 2 have the planar lug boss of cylinder.
The present invention adopts and at jaw body 7 locking cylinder 6 is installed, be threaded connection to fix at locking cylinder 6 and tiltedly carve plate 4, round nut 5 plays the function of self-locking, jaw bearing pin 3 is installed in the jaw body 7 by pin-and-hole, jaw bridge plate 2 is hinged on the jaw body 7 by jaw bearing pin 3, back-moving spring 8 is installed in the back-moving spring hole 10 of jaw body 7, holding screw 9 is installed in 10 bottoms, back-moving spring hole, and the effect of holding screw 9 is to prevent that back-moving spring 8 from coming off in the back-moving spring hole 10 of jaw body 7.When locking cylinder 6 drives when tiltedly carving plate 4 and promoting forward, under the effect of lever principle, jaw bridge plate 2 compresses locking strips 1.
The course of work of the present invention and operation principle:
When whole spindle drum moves to the position that needs processing, utilize hydraulic control system, start locking cylinder 6, tiltedly carve plate 4 and under the effect of locking cylinder 6, promote forward, when the head of jaw bridge plate 2 is arrived on the top, under the effect of lever principle, the other end of jaw bridge plate 2 compresses to the direction of jaw body 7, locked locking strip 1, this moment whole spindle drum under the effect of hydraulic locking mechanism, can guarantee effectively that workpiece is not moved adding man-hour.After the workpiece completion of processing, when spindle drum need to move, locking cylinder 6 shrank, and under the elastic force of back-moving spring 8, jaw bridge plate 2 unclamps locking strip 1, and hydraulic locking mechanism is not at locking state at this moment, and spindle drum can move freely.
