Abstract
The utility model relates to a drill rotation speed intelligent regulating device based on material pressures. The drill rotation speed intelligent regulating device comprises a machine frame and a drill. The machine frame is fixedly connected with fixtures, the drill is driven by a motor connected with a control unit, the machine frame is fixedly connected with fixed seats with slots, the fixed seats are symmetrically distributed on the two sides of the fixtures, the bottom faces of the slots are fixedly connected with guide rods, the guide rods are provided with pressure springs in a sleeved mode, and the guide rods are connected with supporting seats in a sliding mode through the pressure springs. A detection space is formed between the supporting seats and the bottom faces of the slots, pressure sensors are arranged in the detection space, the pressure sensors are connected with the control unit, and pressure threshold values are preset in the pressure sensors. The pressure sensors are used for detecting magnitude of pressure borne by the supporting seats, the control unit is used for regulating the rotation speed of the drill, protection of the drill is reinforced, the service life of the drill is prolonged, machining accuracy of drilling can be improved, and the defective rate is lowered.
Description
Technical field
The utility model relates to machining equipment field, relates in particular to drilling machine.
Background technology
At present, during drilling machine boring, be generally by rotating speed and the feed speed of default drill bit, base material to be processed, in its process, due to the invariablenes turning speed of drill bit, when drilling depth increases, the torsion of drill bit increases, and causes drill bit generation deformation until damage.So the service life of the drill bit of existing drilling machine is shorter, causes replacement cost high, and the precision of boring is not high.
Utility model content
The applicant, for above-mentioned shortcoming of the prior art, studies and improves, and a kind of drill speed intelligent regulating device based on base material pressure is provided, and has effectively strengthened the protection to drill bit, has extended its service life, has reduced cost.
The technical scheme that the utility model adopts is as follows:
A drill speed intelligent regulating device for base material pressure, comprises frame and drill bit, affixed fixture in frame, and drill bit is driven by motor, and motor is connected with control module; The affixed holder with short slot in frame, holder is symmetrically distributed in the both sides of fixture; The bottom surface of short slot is connected with guide rod, is nested with stage clip on guide rod, and guide rod is by stage clip Elastic Sliding connecting support seat; Between the bottom surface of supporting seat and short slot, form a detection space, be provided with pressure sensor in detection space, pressure sensor is connected with control module, is preset with pressure threshold value in pressure sensor.
Further technical scheme is:
On supporting seat, there is locating slot; The ，Qi top, bottom surface that pressure sensor is fixed in short slot contacts with the bottom surface of supporting seat.
The beneficial effects of the utility model are as follows:
The utility model detects the pressurized size of supporting seat by pressure sensor, adjust the rotating speed of drill bit by control module, has not only strengthened the protection to drill bit, has extended its service life, can also improve machining accuracy and the reduction in the numbers of seconds of boring.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is operation principle block diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 1 and Fig. 2, the utility model comprises frame 1 and drill bit 3, affixed fixture 9 in frame 1, and fixture 9 is locked by leading screw 10, and drill bit 3 is driven by motor 2, and motor 2 is connected with control module 12, and control module 12 can regulate the rotating speed of motor 2, the affixed holder 4 with short slot 41 in frame 1, holder 4 is symmetrically distributed in the both sides of fixture 9, the bottom surface of short slot 41 is connected with guide rod 6, on guide rod 6, be nested with stage clip 7, guide rod 6 is by stage clip 7 Elastic Sliding connecting support seats 8, the upper surface of supporting seat 8 has locating slot 81, the size of locating slot 81 is set according to the size of work piece, wherein stage clip 7 has larger coefficient of elasticity, so that it is out of shape under larger pressure is less, between the bottom surface of supporting seat 8 and short slot 41, form a detection space 11, in detection space 11, be provided with pressure sensor 5, pressure sensor 5 is fixed in the bottom surface of short slot 41, its top contacts with the bottom surface of supporting seat 8, pressure sensor 5 is connected with control module 12, in pressure sensor 5, be preset with pressure threshold value, when drill bit 3 boring, the process of drill bit 3 feedings produces pressure to base material, pressure is passed on supporting seat 8, pressure sensor 5 detects the pressure of supporting seat 8, when if pressure is greater than default pressure threshold value, pressure sensor 5 passes to control module 12 by signal, the rotating speed that control module 12 reduces motor 2 is to realize slowly running of drill bit 3, realized the protection to drill bit 3.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
