[0022] Embodiment: as Figures 1-4As shown, a kind of quick positioning device for engraving cutter rod grinding angle, including positioning cylinder base 1, installation sleeve 2 and anti-skid washer 3, positioning cylinder base 1 one end is integrally formed with mounting seat 101 and the other end is provided with positioning insertion hole 103, six cylinder cavities 104 are equidistantly opened on the inner wall of positioning insertion hole 103, movable column 105 is movably inserted in cylinder cavity 104, and movable column 105 penetrates positioning cylinder base 1, limit sheet 106 is integrally formed on movable column 105, and first spring 107 is fixedly sleeved between limit sheet 106 and the inner wall of cylinder cavity 104, ball 108 is rotatably installed on both ends of movable column 105, clamping cylinder 109 is integrally formed on the outer side of positioning cylinder base 1, movable cylinder 110 is movably clamped in clamping cylinder 109, a plurality of second springs 111 are fixedly installed between movable cylinder 110 and the inner wall of clamping cylinder 109, annular groove 112 is formed on the end of movable cylinder 110 away from clamping cylinder 109, anti-skid knob 202 is integrally formed on one end of installation sleeve 2, when using, installation sleeve 2 is screwed in, and movable column 105 is limited to move under the limiting action of movable cylinder 110, and because one end of installation sleeve 2 is in the form of a tapered cylinder, the deeper installation sleeve 2 is screwed in, the greater the force installation sleeve 2 bears, and the installation sleeve 2 deforms to clamp the engraving cutter rod, if the engraving cutter rod needs to be disassembled, only second spring 111 needs to be compressed by pushing movable cylinder 110, and movable column 105 is easily screwed out of installation sleeve 2 for quick assembly and disassembly because the force of movable column 105 is greater than the elastic force of first spring 107, so that movable column 105 is inserted into annular groove 112.

[0023] The cross section of positioning cylinder base 1 is regular hexagonal, six scale lines 102 are equidistantly opened on the outer side of positioning cylinder base 1, when using, positioning cylinder base 1 is divided into twelve parts equidistantly by the design of regular hexagonal and six scale lines 102, and the angle between scale line 102 and the side of positioning cylinder base 1 is 30°, to facilitate adjusting the installation angle of positioning cylinder base 1.

[0024] The depth of cylinder cavity 104 is the same as the depth of annular groove 112, when using, when movable column 105 is inserted into annular groove 112, the locking of installation sleeve 2 is released.

[0025] The outer periphery of installation sleeve 2 and the inner wall of positioning insertion hole 103 are both provided with matching threads, when using, installation sleeve 2 and positioning sleeve are conveniently installed.

[0026] One end of installation sleeve 2 away from anti-skid knob 202 is in the form of a tapered cylinder, when using, the deeper installation sleeve 2 is screwed in, the greater the clamping force is, by the design of tapered cylinder.

[0027] A plurality of grooves 201 are equidistantly opened on one end of installation sleeve 2 away from anti-skid knob 202.

[0028] A plurality of clamping grooves 203 are equidistantly and circumferentially formed on the inner wall of the mounting sleeve 2, a plurality of clamping strips 301 are integrally formed on the outer side of the anti-skid washer 3 corresponding to the clamping grooves 203, and a plurality of anti-skid strips 302 are equidistantly and circumferentially formed on the inner wall of the anti-skid washer 3, in use, the anti-skid washer 3 is sleeved on the lettering cutter rod and clamped into the mounting sleeve 2, and the clamping effect of the clamping strips 301 and the clamping grooves 203 improves the firmness during the rotating process.

[0029] Specifically, in use, the anti-skid washer 3 is sleeved on the lettering cutter rod and clamped into the mounting sleeve 2, and is screwed into the mounting sleeve 2 (the ball 108 plays a smooth role), the movement of the movable column 105 is limited under the limiting effect of the movable cylinder 110, and because one end of the mounting sleeve 2 is in the form of a tapered cylinder, the deeper the mounting sleeve 2 is screwed in, the greater the stress on the mounting sleeve 2, and the mounting sleeve 2 deforms to clamp the lettering cutter rod, if the lettering cutter rod needs to be disassembled, the movable cylinder 110 is only needed to be pushed to compress the second spring 111, and because the stress on the movable column 105 is greater than the elastic force of the first spring 107, the movable column 105 is pushed into the annular groove 112, so that the mounting sleeve 2 can be easily screwed out for quick assembly and disassembly.
