A hand-held electric countersinking chamfering machine is characterized in that the countersinking chamfering machine comprises a machine frame, a magnetic block clamping device which is arranged under the machine frame, used for clamping the workpiece and provided with a magnetic flux switch and a countersinking mechanism which is arranged above the machine frame. The countersinking mechanism comprises a guide post, a support spring which is movably sleeved on the guide post and used for supporting a guide sleeve, the guide sleeve, an electric engine which is fixedly connected with one side of the guide sleeve, a speed reduction gear box and a countersink drill cutter which are connected in order. The utility model can utilize the processed workpiece as a platform to take the magnetic block which is used as the clamp and able to switch the magnetic flux as the fastening force and tightly fix the countersinking mechanism on the workpiece through the magnetic force to machine the countersinking. The chamfering machined surface is provided with high degree of finish, no burr, accurate depth and uniform size. The complete machine also has the advantages of small structure, light weight, good energy-saving effect and low manufacturing cost, etc.

Description

Hand-held electric spot-facing beveler
Technical field
The utility model relates to a kind of portable electric tool, particularly a kind of hand-held electric spot-facing beveler.
Background technology
In manufacturings such as machine die five metals, the metallic element that is processed all is connected with rivet by screw, so on metallic element, be drilled with many big and small holes, the hole that processes with drill bit on drilling machine all has burr, burr, in order to reach the assembly technology requirement, 45 ° spot-facing chamfered must be carried out in these holes that have the burr burr, also be on drilling machine, to carry out this procedure of chamfering at present, must be the chamfering about (0.1-3.5) * 45 ° processing the nominal standard size on the end face in hole by the size in hole during operation, particularly during through hole, two-sidedly all to carry out chamfer machining, chamfering will be carried out more bit change on drilling machine, displacement, centering, work steps such as locking board, operation is trouble comparatively, and is very time-consuming again, and taken a large amount of production times of lathe, big at operating process Fraquent start motor power consumption, when adopting large-sized drill machine to finish chamfer machining, because large-sized drill machine cost height, so processing charges are also higher.
The utility model content
The purpose of this utility model is a kind of hand-held electric spot-facing beveler of design, and it has simple in structure, operate light, production efficiency height, characteristics such as crudy is good.
The utility model is realized with following technical scheme: this spot-facing beveler is by frame, the spot-facing mechanism of playing clamping workpiece magnetic patch clamping device that use and that have Flux switch (inhaling piece but its structure is equivalent to the magnet of the switch magnetic flow of being joined on the used usually dial gauge instrument of metalworking workshop) and being installed on the frame top that is installed on frame below forms, and wherein spot-facing mechanism is again by the guide pillar that is connected successively, pivot bush unit is on guide pillar and be used for the support spring of support guide pin bushing, guide pin bushing, the motor of fixedlying connected with guide pin bushing one side, gear reduction box and counterbit cutter constitute.
In the technical solution of the present utility model, on described frame, also be fixed with a spacing bolt column of using, on bolt column, be connected with and touch mutually to control the stop nut regulated of cutting output with guide pin bushing.
In technical solution of the present utility model, have the scale of ten five equilibriums on described (adjusting spot-facing working depth) spacing surface with adjustable nut, as be carved into ten five equilibrium lines, every line value equals 0.1mm, with the degree of depth that the handled easily workman regulates spot-facing processing, accomplish accurately spacing.
In technical solution of the present utility model, also be equipped with a movable left handle of amounting in the outside of described frame (left-external side), also be equipped with a movable right handle of amounting in the outside (the right outside) of motor.
Use principle method of the present utility model is as follows: this machine can utilize processed workpiece as platform, but the magnetic patch magnetic force of the switch magnetic flow that will use as anchor clamps is as fastening force, spot-facing mechanism is fastened on the workpiece with magnetic force absorption, the circular hole on the workpiece is carried out spot-facing processing.With reference to accompanying drawing, its specific operation process is as follows: the available right hand down workpiece pressing of right handle of holding with a firm grip, force counterbit (head) to aim at the center of circular hole to be processed, the left hand left handle of holding with a firm grip, and open Flux switch, this moment, whole spot-facing mechanism was fixed on the workpiece by magnetic force, loosen the right hand, make the counterbit head leave workpiece a little, start power switch simultaneously, motor drives the counterbit head by gear reduction box and rotates, this moment is by the bottom right handle, make the counterbit cutting workpiece, by the spot-facing time of an about 0.5-3 in hole of the general processing of size second in hole, when reaching the spacing position of being set up.Just loosen the right hand, the powered-down switch under the effect of support spring, pushes up motor and spot-facing mechanism from workpiece, and the closed magnetic flux switch just finishes the spot-facing processing in this hole, also complete machine can be moved on workpiece simultaneously next hole is processed.Counterbit head described in the utility model can adopt 90 ° of taper multiple-cutting-edge counterbits that the automatic centering effect is arranged, and as when cutter departs from the center, causes monolateral load resistance, will pass the center, hole to counterbit under the downforce effect.The cutting output adjusting nut can be adjusted the spot-facing chamfering degree of depth.
Compare with the spot-facing beveler of the big drilling machine of prior art, have simple to operate, easy to use, work efficiency improves more than ten times, and the chamfer machining face that adopts counterbit to process is highly polished, and no burr, the degree of depth are accurate, size is unified, it is small and exquisite in light weight that complete machine also has structure, good energy-conserving effect, the low advantages such as (quite electric tool prices) of cost cost.
Description of drawings
Fig. 1 is a kind of overall structure schematic diagram of the present utility model.
The specific embodiment
With reference to accompanying drawing as can be known, when the utility model is made in specific design, its structure comprises frame 5 and is installed on the magnetic that has Flux switch 1 (iron) the piece clamping device 4 of frame 5 belows, frame 5 passes on left hinge 3 and is provided with the left handle 2 that can amount to, also add a movable right handle 16 of amounting to (connecting) by hinge pin axle 15 in the right outside of motor 12, frame 5 upper fixed have guide pillar 10, movable sleeve is connected to support spring 8 and guide pin bushing 9 and clamp nut 11 on the guide pillar 10, motor 12 by bolt 14 with after the gear reduction box 17 that is positioned at the motor front end is connected, be fixedly installed in a side of guide pin bushing 9 again by threaded connector 13, and constitute spot-facing mechanism together, support spring 8 should support the whole spot-facing mechanism that comprises motor weight, the output shaft of reduction gear box 17 connects counterbit head 18 with Morse's taper, just can on workpiece 19, carry out the spot-facing chamfer machining, the stopping means that the caging bolt post 7 that can regulate the spot-facing depth dimensions and adjusting nut 6 thereof constitute also is housed on frame 5, on the circumference of the upper surface of adjusting nut 6, be carved with the scale of ten five equilibrium lines, spot-facing adds man-hour, guide pin bushing 9 can touch with adjusting nut 6 in folding process, plays the position-limiting action to the spot-facing working depth.
