The extension of handle of a knife link block 2 and the extension of cutter connecting cylinder 7 are provided with bolt hole of working in coordination, and pass through hexagon-headed bolt They can be linked together with hex nut, shank portion and cutter body are linked together indirectly.
The ball assembly includes fulcrum bearing 8, ball 9 and retainer 10, and the retainer 10 is fixed on the fulcrum bearing 8 Lower part, the ball 9 be mounted on retainer 10 in.There are multiple spherical pores on the retainer 10, can install multiple described Ball 9 further reduces machined surface roughness and is obviously improved processing efficiency.The ball 9 can be selected sintered carbide ball or Person's Ceramic Balls are realized and the workpiece of different hardness are processed, and expand processing object range.
For the handle of a knife 1 into cone shape, upper end center is provided with threaded hole, can be by the main shaft institute clamping of the equipment such as milling machine. Handle of a knife 1 and handle of a knife link block 2 have guide frame, are positioned convenient for keyway and each threaded hole.Handle of a knife 1 and handle of a knife link block 2 are by just Vertical soket head cap screw connection.
The exterior portion of the cutter body is cutter connecting cylinder 7, and the inside part is force bearing plate 3, power respectively from top to bottom Sensor 4, sensor fixed seat 5, excellent power glue 6, ball bearing seat 8, ball 9, retainer 10.Cutter is during pushing, work Part transmits the active force of cutter from bottom to top, thus in order to it is more accurate, cutter is more easily described, the description to cutter body Also using mode from bottom to top.
The fulcrum bearing 8 and retainer 10 have spherical retaining hole, and ball 9 is located in spherical pore and can freely roll It is dynamic.Outside the part protrusion retainer 10 of ball 9, for workpieces processing.Freely rolling for ball 9 can ensure that ball abrasion is equal It is even, so as to extend ball service life, it ensure that machining accuracy.Sintered carbide ball or Ceramic Balls may be selected in the ball. Fulcrum bearing 8 and retainer 10 are positioned and are fixed by two axis pins, then are attached by four positive screws.This When, fulcrum bearing 8, ball 9 and retainer 10 are used as unitary components, ensure that they can rotate simultaneously.
The excellent power glue 6 is located at 8 top of ball bearing seat, and has certain interval with the inner wall of cutter connecting cylinder 7.Excellent power glue It is a kind of a kind of new material between plastics and rubber, compressive deformation small characteristic good with intensity.Excellent power glue 6 exists Compressive deformation occurs during by axial force, and slight expansion occurs.It is excellent when excellent power glue 6 is limited by 7 inner wall of cutter connecting cylinder The compressive strength of power glue becomes much larger.Therefore, excellent power glue 6 not only provides certain compressive deformation, but also provides comparable compression Intensity ensure that cutter head while bearing centainly to roll power, can be eliminated entirely or partly because of workpiece surface out-of-flatness band The processing vibration come.
The lower part of the sensor fixed seat 5 is provided with threaded hole, and sensor fixed seat 5 is located at the top of excellent power glue 6.It is excellent Power glue 6, retainer 10 are provided with central through hole, and ball bearing seat 8 is provided with stepped hole.By soket head cap screw unitary components (Fulcrum bearing 8, ball 9 and retainer 10), excellent power glue 6 be connected to ball bearing seat 8.The purpose designed in this way is:Fulcrum bearing 8, Ball 9 and retainer 10 belong to wear part, and after they wear, we only need to dismount soket head cap screw, one more renewed Body formula part(Fulcrum bearing 8, ball 9 and retainer 10).Therefore, replacing construction is saved, improves processing efficiency.
The top of the sensor fixed seat 5 is provided with hole and slot, and force snesor 4 is located in sensor fixed seat 5, power sensing The top of device 4 is force bearing plate 3, is handle of a knife link block 2 above force bearing plate, two upright soket head cap screws are handle of a knife link block 2 and force bearing plate 3 link together;Force bearing plate 3 and sensor fixed seat 5 are installed with contour sleeve 13 in symmetrical both sides.Contour set Cylinder is a kind of cannulated sleeve.The soket head cap screw of handstand passes through the centre bore of contour sleeve 13, and sensor fixed seat 5 is connected to On handle of a knife link block 2.The effect of contour sleeve is to ensure that there are certain between force bearing plate 3 and sensor fixed seat 5 in this cutter Distance.The no and force bearing plate contact in a free state of sensor 4.When cutter depresses workpiece surface, sensor fixed seat 5 Sensor 4 is driven to move upwards, until contacting simultaneously stress with force bearing plate 3.In this process, contour sleeve 13 plays guiding and makees With.At this point, pressure signal is output to display instrument by force snesor 4 by signal connecting line.By adjusting cutter in workpiece table The feed distance in face can obtain the static starting force of required rolling and processing.Before rolling and processing, withdrawal force sensor side is needed Signal connecting line, cutter is avoided to be wound when rotating.
The handle of a knife link block 2, force bearing plate 3, sensor fixed seat 5, excellent power glue 6, ball bearing seat 8 and retainer 10 Lateral location is provided with keyway.Cutter connecting cylinder 7 is provided with keyway in corresponding position.It is installed between aforementioned components and cutter connecting cylinder 7 Long key 21, for transmitting torque.The axial restraint of long key is fixed by the holding screw 17 being mounted on handle of a knife link block 2.
Cutter is sleeved on the nozzle holder on cutter connecting cylinder 7 not with the quasi- east of cutter connecting cylinder 7 when being rolled, cold But gas is nearby sprayed by cooling nozzles to ball;Due to ball, nearby there are four vacuum generation mouths so that near ball Strong draught head is generated, so as to which cooling gas be made to form fine and close lubricant layer on ball surface, not only reduces the temperature of ball, Lower the abrasion of ball simultaneously.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as Without the technical solution that creative work can be realized on the basis of above-described embodiment, it is regarded as falling into patent of the present invention Rights protection scope in.
