Abstract
The utility model relates to a device capable of fast dismounting a drill on a driller. A driller body (1) is provided with a main shaft (2). A drill sleeve (6) is internally embedded into the main shaft (2). A drill (7) is internally arranged in the drill sleeve (6). A sleeve (4) is connected with the main shaft (2) through a pin shaft (5). A nylon sleeve (3) is installed in a gap between the sleeve (4) and the main shaft (2). Two ends of the nylon sleeve (3) are respectively fixed with two ends of the sleeve (4) through bolts (8). The outer surface of the sleeve (4) is clamped by the top end of the pin shaft (5), and the other end of the pin shaft (5) is tightly fixed by a nut (9). The device capable of fast dismounting the drill on the driller is convenient to use, safe and fast. Auxiliary time of replacing the drill is saved, labor intensity of an operator can be relieved, and production efficiency is improved. The device capable of fast dismounting the drill on the driller is especially suitable for an assembly line and a lean production line, handheld time is reduced, effective operating time is increased, and production efficiency can be improved by from 5% to 10%. After the device capable of fast dismounting the drill on the driller is assembled in the production line, workers at the production line accepts the device capable of fast dismounting the drill on the driller, and the device capable of fast dismounting the drill on the driller is popularized and applied.
Description
Technical field
The utility model belongs to a kind of pushing-unloading device, is specifically related to a kind of drilling machine speed and unloads drill bit device.
Background technology
At present, in the specialized factory that produces automobile brake drum, when the processing bolt hole, for some products that hole system is many, batch is large, need repeatedly change the drill bit of different-diameter, unload the taper shank drill bushing with traditional wedge, a hand steered drill bit, another hand knocks with the hammer reinforcing, drill bushing is unloaded in the drill press spindle hole, this mode is more time-consuming and dangerous, is unfavorable for streamline production, affects productive temp.
Summary of the invention
The utility model provides a kind of drilling machine speed to unload drill bit device in order to address the above problem, and this device utilizes up and down flexible power and the reaction force that device is produced of drill press spindle, and the drill bit tapered sleeve is extruded in spindle hole, reaches the effect of quick den bohrkopf abbauen.
The technical solution of the utility model: a kind of drilling machine speed is unloaded drill bit device, and it comprises: lathe bed 1, main shaft 2, nylon jacket 3, sleeve 4, bearing pin 5, drill bushing 6, drill bit 7, screw 8 and nut 9 are provided with main shaft 2 on the lathe bed 1, be inlaid with drill bushing 6 in the main shaft 2, be provided with drill bit 7 in the drill bushing 6, described sleeve 4 is connected with main shaft 2 by bearing pin 5.
In the gap of described sleeve 4 and main shaft 2 nylon jacket 3 is installed, this nylon jacket 3 is fixing with screw 8 respectively with the two ends of sleeve 4.
The outer surface of sleeve 4 is blocked on the top of described bearing pin 5, and the other end is fastening with nut 9.
The utility model compared with prior art has following beneficial effect: this device is convenient, safety, quick, saved the non-cutting time of bit change, can alleviate the operative employee labour intensity and and enhance productivity, be particularly useful for streamline and lean production line, reduce the hand-held time, increased effective operation time, can enhance productivity 5% to 10%, behind this device of line configuration, be subject to worker at the production line's approval and obtained applying.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the left view of the utility model structure.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of drilling machine speed is unloaded drill bit device, it comprises: lathe bed 1, main shaft 2, nylon jacket 3, sleeve 4, bearing pin 5, drill bushing 6, drill bit 7, screw 8 and nut 9, be provided with main shaft 2 on the lathe bed 1, be inlaid with drill bushing 6 in the main shaft 2, be provided with drill bit 7 in the drill bushing 6, sleeve 4 mounting hole that main shaft 2 usefulness bearing pins 5 pass main shaft 2 of packing into connects, see Fig. 2, the outer surface of sleeve 4 is blocked on the top of bearing pin 5, and the other end is fastening with nut 9, in the gap of sleeve 4 and main shaft 2 nylon jacket 3 is installed, the effect of nylon jacket 3 is to guarantee that sleeve 4 moves up and down Shi Buhui and pulls main shaft 2, and nylon jacket 3 is fixing with screw 8 respectively with the two ends of sleeve 4.When by operating grip main shaft 2 being moved up, when band moving sleeve 4 is moved upward to lathe bed 1 simultaneously, can produce the anti-power of work in sleeve 4, the bearing pins 5 that this reaction force meeting interlock penetrates in main shaft 2 and the sleeve 4 have the trend power that moves down, the main shaft 2 interior drill bushings 6 of will packing into extrude in mounting hole, reach the function that speed is unloaded drill bit.
