By using the clamp of the utility model, a cutter or a drilling head can be installed and disassembled easily and conveniently. The utility model has the advantages of high loading and unloading speed, artful structure, reliable operation, convenient operation, rapid cutter change, etc. The clamp is especially suitable for the associated operation of drilling holes, expanding holes, chamfering hole openings and rapidly changing cutters in the same hole site.
Description
Technical field the utility model relates to a kind of anchor clamps, in particular for the tool mounting of clamping cutter or drill bit.
The existing anchor clamps of background technology all are cutter or drill bit to be tightened from side direction with screw to be fixed on the chuck when clamping cutter or drill bit, work under the drive of anchor clamps then.This structure and using method, just give cutter or drill bit installation, shirk and bring very big inconvenience, during operation especially in the open air, tend to take place that tightening tool can't find for the moment loses or situation, if at this moment will install or shirk the just inconvenience more of cutter, drill bit.
The summary of the invention technical problem to be solved in the utility model is to propose a kind of anchor clamps that can install or shirk cutter easily, easily and quickly.
For solving the problems of the technologies described above, a kind of anchor clamps of the utility model comprise chuck body, top pressure spring, outer sliding sleeve, sliding spring, inner sliding sleeve, steel ball, jacking block and briquetting, described top pressure spring places the inside cavity of being offered in the described chuck body, described inner sliding sleeve is located in the cavity of described chuck body, the outside of described top pressure spring, the outboard end of described top pressure spring withstands on the medial extremity of described inner sliding sleeve, described jacking block is positioned at the outboard end of described inner sliding sleeve, described outer sliding sleeve is sheathed on the outside of described chuck body, described sliding spring one end is fixed on the outboard end of described outer sliding sleeve, offer briquetting tank and steel ball tank on the wall of described chuck body end, corresponding briquetting groove and the steel ball groove of being provided with on the madial wall of described outer sliding sleeve, the corresponding steel ball groove that is provided with on the lateral wall of described inner sliding sleeve.
Above-mentioned a kind of anchor clamps, it also includes dust cap, and described dust cap is connected on the end wall of the described chuck body outside, and the other end of described sliding spring withstands on the described dust cap.
Above-mentioned a kind of anchor clamps, the end sidewalls of described chuck body is provided with the briquetting station location marker.
Above-mentioned a kind of anchor clamps, it also includes air ring, driving lever, sealing ring and cooling fluid inlet, described air ring is located on the described chuck body, both junctions are provided with described sealing ring, described cooling fluid inlet is located on the described air ring, and with described air ring on the pipeline connection offered, this pipeline is communicated with the cavity of described chuck body.
The utility model, inserts the end of cutter or drill bit in the cavity of chuck body, and firmly inwardly pushes up when needs mounting cutter or drill bit owing to adopted above-mentioned technical pattern.At this moment, stressed inside slip of inner sliding sleeve and extruding top pressure spring, briquetting and steel ball then move to the cavity direction, block the end of cutter or drill bit until briquetting.Like this, cutter or drill bit just are fixed on the anchor clamps, finish dress cutter process.The bottom of steel ball then enters in the steel ball groove on the inner sliding sleeve, and outer sliding sleeve inwardly slides under the effect of sliding sleeve spring.When needs shirk cutter or drill bit, to the extrapolation outer sliding sleeve, along with its briquetting groove and steel ball groove gradually with chuck body on briquetting tank and steel ball recesses coincide, the top of briquetting and steel ball can move up.At this moment, under the effect of top pressure spring restoring force, inner sliding sleeve can outwards slide, and promotes to move on briquetting and the steel ball, breaks away from the end of cutter or drill bit fully until briquetting.Like this, cutter or drill bit just come off to finish automatically and unload cutter.Thereby employing the utility model anchor clamps can be installed easily, easily and shirk cutter or drill bit, and handling speed is exceedingly fast.It has advantages such as delicate structure, use is reliable, easy to operate, tool changing is quick, and the utmost point is suitable for holing in position, same hole, reaming, aperture chamfering rapid changing knife integration of operation.Dust cap is set plays and prevent that dust from entering, to guarantee the flexible operating of anchor clamps.The briquetting station location marker can be so that the assurance of cutter or drill bit insertion method when installing.The setting of air ring and corresponding component, when can make cutter or drill bit can carry out outer cooling, the interior cooling in the time of also can realizing work, promptly cooling fluid can inlet, pipeline and anchor clamps cavity to cutting edge cool off, save cooling fluid, especially be suitable for open-air lack of water operation.
