Because the screw rod sliding mechanism is a common structure in the field of mechanical manufacturing for realizing movable connection between two components, specific structures of the screw rod sliding mechanism are not described herein any more, but the protection scope of the patent is not limited to the screw rod sliding mechanism, and any mechanical structure or adjustment mode capable of realizing similar adjustment rules in the patent is within the protection scope of the patent. The upper end surface of the first movable table 2 is an inclined surface, and the upper end of the first movable table 2 is provided with a second movable table 4 which can move left and right. Because the up end of first movable table 2 is the inclined plane for whole second movable table 4 slopes to set up around, and the up end of this second movable table 4 rotationally is provided with back angle face and grinds seat 5, and back angle face grinds seat 5 and is equipped with the mounting hole 10 that is used for fixed mounting holder 100. The cartridge 100 is a tool for fixedly mounting the milling cutter a. Since the specific structure of the holder 100, the specific structure of the rear corner face grinding seat 5 and the specific assembly structure of the two are all prior art, those skilled in the art can understand and use the two structures according to the drawings of the specification and in combination with the prior art, and will not be described herein again.

Referring to fig. 1 and 2, the positioning block 121 is disposed on the base 1, and a dial indicator 22 for measuring a forward-backward movement distance of the first movable stage 2 is disposed between the first movable stage 2 and the positioning block 121. Specifically, the positioning block 121 is fixed on the bottom plate 12 of the machine base 1 through a screw 122 matching with the strip screw hole and capable of moving back and forth.

Referring to fig. 1 and 2, in particular, the dial indicator includes a housing 220 and a measuring rod 222, a blind hole 20 is formed at the rear end of the first movable table 2, and a sleeve 221 of the housing 220 is inserted into the blind hole 20 and locked by a locking screw 7, so that the housing 220 is fixedly mounted on the first movable table 2. The measuring head of the measuring rod 222 is movably inserted into the blind hole 20, and an elastic member 6 for moving the measuring rod backward is disposed between the measuring head and the first movable table 2, so that the stop cap of the measuring rod 222 is always supported against the positioning block 121. Preferably, the elastic member 6 is a compression spring. Because the sleeve 221 of the shell 220 is inserted into the blind hole 20, the sleeve 221 and the measuring head of the measuring rod 222 are located in the blind hole 20, so that the amount of metal dust generated during grinding can be reduced well, even fine metal dust generated during grinding can be prevented from falling to one end of the measuring head of the measuring rod 222, a good dustproof effect can be achieved, and the accuracy and the service life of the dial indicator can be guaranteed.

Referring to fig. 1 and 2, in order to further improve the dust-proof performance, elastic extension tubes 8 for sleeving the measuring rod 222 are respectively connected between the housing 220 and the rear end of the first movable table 2 and between the housing 220 and the positioning block 121. Preferably, the elastic bellows 8 is a bellows. In order to fix the elastic extension tube 8 and further improve the dust-proof effect, annular grooves (not shown in the figures) for connecting the elastic extension tube 8 may be disposed on the surfaces of the housing 220, the positioning block 121 and the first movable table 2. Of course, the dustproof manner of the dial indicator is not limited to the elastic extension tube, and any suitable existing dustproof means can be used instead.

Referring to fig. 1 and 2, the positioning block 121 is provided with a first through hole 131 and a first blind hole 132 extending in the front-rear direction, and the positioning block 121 is further provided with a groove 133 penetrating through the first through hole 131 and the first blind hole 132. The stop cap of the measuring rod 222 is disposed at the front end of the first through hole 131 in a front-back adjustable manner, the rear end of the first through hole 131 is assembled with a first screw 134 for supporting the stop cap in a threaded manner, and the first blind hole 132 is assembled with a second screw 135 in a threaded manner. The first through hole 131, the first screw 134, the first blind hole 132, the second screw 135 and the groove 133 form a dial indicator zero setting mechanism. The specific using method comprises the following steps: the stop cap of the measuring rod 222 is adjusted forwards and backwards by rotating the first screw 134, so that the reading of the dial indicator is zero; then, the second screw 135 is screwed, and due to the action of the second screw 135, the portion of the positioning block 121 located behind the slot 133 is slightly bent forward, and the rear section of the first through hole 131 is slightly bent forward, so as to fasten the first screw 134 to the first through hole 131.

Referring to fig. 1, 2 and 3, the working mode of the present invention is as follows: the milling cutter a is inserted into the clamping hole 1001 of the clamping base 100 in advance, the extension length of the milling cutter a is adjusted to a proper position, and the milling cutter a and the clamping hole are locked by a screw 1002. The radius R of the milling cutter a is measured, the first movable table 2 is moved backward by rotating the adjusting knob 21, and when the axial line of the mounting hole of the rear corner face grinding seat 5 is flush with the front end face of the grinding disc 32, the dial indicator 22 reads 0. The first movable table 2 will be moved forward by turning the adjustment knob 21 until the dial indicator 22 reads substantially R. The holder 100 is fixed to the mounting hole 10 of the rear corner face grinding holder 5, and the motor 31 is started to rotate the grinding disk 32. The second movable table 4 is moved rightward so that the cutting edge of the milling cutter a is positioned in front of the grinding disc 32, thereby completing the feed operation. Then the rear angle surface grinding seat 5 is rotated 90 degrees anticlockwise, and a front end of the grinding disc 32 is utilized to grind a rear angle surface a2 on a cutter head of the milling cutter a; the rear corner face grinding seat 5 is rotated clockwise by 90 degrees, and then the second movable table 4 is moved leftward, so that the cutter head of the milling cutter a is positioned on the left side of the grinding disc 32, and the cutter retracting operation is completed. The clamping base 100 is rotated by 180 degrees and then is fixed on the mounting hole 10 of the regrinding base 5 again, and another rear corner face a2 is ground in the same manner as described above.

To sum up, the utility model discloses a contrary conventional ground is fixed the casing of percentage table on mobilizable first movable table, reuses the measuring head that the measuring stick was held in elastic component top for the percentage table is read grow gradually when the front end of the relative abrasive disc of first movable table moves towards the right, normally shows. Simultaneously, the two ends of the measuring rod of the dial indicator are shielded through the blind hole, the elastic extension tube and the like, so that fine metal chips or other dust are reduced or even prevented from falling to the measuring rod of the dial indicator, and the accuracy and the service life of the dial indicator are guaranteed.
