Abstract
The invention relates to a device for locking a boring bar, which is used for preventing the boring bar from being pulled out of a boring machine main shaft under a pulling force during reverse boring process. The device comprises a first wedge block and a second wedge block, wherein the first inclined plane of the first wedge block is contacted and engaged with the first inclined plane of the second wedge block, the second inclined plane of the first wedge block is contacted with the side wall of a mounting hole of the boring machine main shaft, the second inclined plane of the second wedge block is contacted with the side wall of a mounting groove of the boring bar, a limiting and locking part is fixed on the first inclined plane of the first wedge block, a limiting part is fixed on the second inclined plane of the second wedge block, an adjustable locking hole is formed on the limiting and locking part, a locking bolt hole is formed on the second wedge block, and a locking bolt passes through the adjustable locking hole and then is connected into the locking bolt hole in a threaded manner. The device can prevent the boring bar from being pulled out under a pulling force and has the advantages of being convenient in fabrication and having good safety.
Description
Technical field
The present invention relates to a kind of for the boring bar locking device that prevents that boring bar from not pulled out from boring spindle by pulling force in when falling the boring.
Background technology
During the boring machine routine work, boring bar and boring spindle taper hole pass through taper fit.Boring bar is subjected to inside pressure during work, does not have the problem that is drawn out.And when boring bar when falling the boring, boring bar is subjected to an outside pulling force, at this moment just needs a locking device prevent that boring bar is drawn out.Conventional locking device is the integral article of a fixed size, because structural reason has only an end band step, the danger that skids off is to a certain degree arranged in boring bar work; On the other hand, because fixed size, so can not be general on the different lathe of main shaft size.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of boring bar locking device that can prevent that boring bar is drawn out by pulling force is provided.
According to technical scheme provided by the invention, described boring bar locking device, comprise first voussoir and second voussoir, first inclined-plane of first voussoir contacts cooperation with first inclined-plane of second voussoir, second inclined-plane of first voussoir contacts with the installing hole sidewall of boring spindle, second inclined-plane of second voussoir contacts with the mounting groove sidewall of boring bar, fix limited position locking portion on first inclined-plane of first voussoir, fixedly there is limiting section on second inclined-plane at second voussoir, offer the adjusting locking hole at spacing tight lock part, offer the locking screw keyhole at second voussoir, clamping screw is screwed onto in the locking screw keyhole after passing and regulating locking hole.
Offer the stripper bolt hole at second voussoir.
The present invention can prevent that boring bar is drawn out by pulling force, and the present invention has advantages such as simple for production and security are good.
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: this boring bar locking device, comprise first voussoir 1 and second voussoir 2, first inclined-plane of first voussoir 1 contacts cooperation with first inclined-plane of second voussoir 2, second inclined-plane of first voussoir 1 contacts with the installing hole sidewall of boring spindle 3, second inclined-plane of second voussoir 2 contacts with the mounting groove sidewall of boring bar 4, fix limited position locking portion 1.1 on first inclined-plane of first voussoir 1, fixedly there is limiting section 2.1 on second inclined-plane at second voussoir 2, offer adjusting locking hole 1.2 at spacing tight lock part 1.1, offer locking screw keyhole 2.2 at second voussoir 2, clamping screw 5 is screwed onto in the locking screw keyhole 2.2 after passing and regulating locking hole 1.2.
Offer stripper bolt hole 2.3 at second voussoir 2.
When boring bar was subjected to pulling force, under first ramp effect of first inclined-plane of first voussoir 1 and second voussoir 2, first voussoir 1 and second voussoir, 2 mobile trends were along the radial direction of boring bar 4 outside, so can not move inward along the radial direction of boring bar 4 and produce loosening; First voussoir 1 has spacing tight lock part 1.1, the second voussoirs 2 and has limiting section 2.1, and this locking device can not skidded off along boring bar 4 radial direction; The spacing tight lock part 1.1 of first voussoir 1 is opened and is regulated locking hole 1.2 and be mounting hole, in guaranteeing hexagonal clamping screw 5 and locking screw keyhole 2.2 smoothly closing.
