Abstract
The invention relates to a device for rapidly detaching a drill bit of a drilling machine. According to the device, a main shaft (2) is arranged on a machine body (1), a drilling sleeve (6) is embedded in the main shaft (2), the drilling bit (7) is arranged in the drilling sleeve (6), and a sleeve (4) is connected with the main shaft (2) through a pin shaft (5). A nylon sleeve (3) is installed in the gap between the sleeve (4) and the main shaft (2), and two ends of the nylon sleeve (3) and two ends of the sleeve (4) are fixed by bolts (8) respectively. The top end of the pin shaft (5) is snaps the outer surface of the sleeve (4), and the other end of the pin shaft (5) is fastened by a nut (9). The device is convenient, safe, fast, capable of saving auxiliary time for changing drill bits, reducing labor intensity of operators and improving efficiencies and particularly applicable to assembly lines and lean production lines; and by means of the device, hand-holding time is reduced, effective operating time is increased, the production efficiencies can be improved by 5%-10%, and the device is approved by workers at the production line and popularized and applied when the device is configured in the production line.
Description
Technical field
The invention belongs to a kind of pushing-unloading device, be specifically related to a kind of drilling machine speed and unload 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 present invention 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.
Technical scheme of the present invention: 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 present invention 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 invention,
Fig. 2 is the left view of structure of the present invention.
The specific embodiment
The present invention 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.
