Abstract
The utility model discloses a straight shank special-use hand-fastening quick fitting chuck. The tail section of a drill bit (1) of the straight shank special-use hand-fastening quick fitting chuck is processed into pin shape and inserted into the clamping groove of one end of a transmission shaft (3), the other end of the transmission shaft (3) is provided with a small hole, a positioning pin (8) is arranged in the hole, the center of a tailcone is provided with a reposition sleeve (5), the wall face of the reposition sleeve (5) is provided with a sliding groove (10) with three positioning holes (11), the top end of the reposition sleeve (5) is provided with a baffle plate (7), and a spring (9) is arranged below the baffle plate (7). The operation for assembling and disassembling the drill bit is very convenient because of the design. The utility model has the advantages of long service life, time saving, labor saving, simple manufacture and easy popularization.
Description
The utility model relates to a kind of anchor clamps, particularly a kind of manually fastened quick-mounting chuck.
Used chuck on the existing lathe, drill bit is mainly fixed by the chucking power of three-jaw standard cartridge, dismounting inconvenience, and damage chuck easily, cause the very big waste of material in man-hour.
The utility model has carried out improving design to aforementioned anchor clamps, and purpose is to utilize new design to provide a kind of and can installs and removes fast and durable chuck.
Described chuck comprises drill bit, three-jaw standard drill chuck, tail cone; It is characterized in that described drill bit (1) afterbody is processed in the draw-in groove of pin shape insertion power transmission shaft (3) one ends, the other end of power transmission shaft (3) has an aperture, and alignment pin (8) is housed in the aperture; Transposition cover (5) is equipped with by trip bolt (6) in tail cone (4) central authorities, has the sliding tray (10) that has three locating holes (1) on the wall of transposition cover (5), and baffle plate (7) also is equipped with on transposition cover top; Power transmission shaft (3) is inserted in the transposition cover (5), between the power transmission shaft (3) of the top of transposition cover (5) and insertion spring (9) is housed.During work, at first will insert through the drill bit afterbody after the processing repacking in the draw-in groove of power transmission shaft (3) one ends, power transmission shaft this moment (3) can slide up and down in the sliding tray (10) of transposition cover (5); Rotary drilling-head and power transmission shaft, the alignment pin of one end is stuck in the locating hole (11) of sliding tray (10), just realized the operation of dress drill bit, utilize the elastic force of spring (9) can select 3 kinds of (upper, middle and lower) drill bits to insert deep degree as required, thereby can select the length of drill bit working position, with hand band locking drill chuck (2), will get final product work in tail cone (4) the insertion tapered bore of machine tool spindle then.Drill chuck (2) mainly plays drill bit centering effect at this moment.
Chuck described in the utility model by the improvement design to existing chuck, makes that the operation of mounting or dismounting drill bit is very easy to be fast, and then has increased chuck service life, has the advantage of saving of work and time, and makes and produce simply, very is easy to promote adopt.
