In order to facilitate the limiting of the stop block 302 and the removal of the cutter after the cutter is replaced, the stop block 302 is hinged to the sliding block 301, the sliding block 301 is further provided with a protruding block 303 for limiting the stop block 302 to turn towards the direction of the milling cutter, the protruding block 303 is located on the side of the stop block 302 away from the cutter bar limiting portion 2, so that when the cutter needs to be replaced, the stop block 302 can be erected, the screw 300 is screwed again, the stop block 302 abuts against the side face, facing the milling cutter 5, of the protruding ring 401, due to the existence of the protruding block 401, the stop block 302 cannot turn towards the direction of the milling cutter 5, and the cutter bar 4 can be well clamped by the stop block 302 and the cutter bar limiting portion 2. In addition, two guide rods 304 parallel to the screw 300 are arranged in the groove 101, the two guide rods 301 are respectively positioned at two sides of the screw 300, and the two guide rods 304 both penetrate through the slider 301 to guide the slider 301 in the process that the slider 301 moves on the screw 300.
In order to facilitate screwing and moving the limiting device, a T-shaped handle 305 can be further arranged, a through hole corresponding to the screw rod 300 is formed in the base 1, the T-shaped handle 305 penetrates through the through hole to be fixedly connected with the screw rod 300, and the screw rod 300 is rotated by rotating the T-shaped handle 305.
When the milling cutter is replaced by applying the milling machine tool bar tool changing clamp of the embodiment, as shown in fig. 3 and 4, the stop block 302 is erected, the T-shaped handle 305 is rotated to move the slide block 301 and the stop block 302 thereon to be close to the T-shaped handle 305, and then the side of the tool bar 4, which is located on the bulge loop 401 and is far from the milling cutter 5, is inserted into the limit loop 201, the two limit blocks 202 are correspondingly clamped in the limit grooves 402, the side of the bulge loop 401, which is far from the milling cutter 5, is tightly abutted against the side of the limit loop 201, which is far from the milling cutter 5, the rotation of the tool bar 4 and the movement of the tool bar 4, which is far from the milling cutter, are limited, the T-shaped handle 305 is screwed, the slide block 301 and the stop block 302 thereon are moved towards the tool bar limit portion 2, when the stop block 302 is tightly abutted against the side of the bulge loop 401, at this moment, the cutter bar 4 is firmly clamped between the cutter bar limiting part 2 and the stop block 302, the cutter bar thread groove 400 is unscrewed by using a special spanner, the stress of the cutter bar 4 is uniform, the milling cutter 5 can be conveniently taken down and replaced by a new milling cutter, and the end cover 400 of the cutter bar 4 is screwed by using the special spanner to complete the assembly of the new cutter. Then, the handle 305 is turned to the T-shaped handle, so that the slide block 301 and the stop block 302 thereon move towards the milling cutter 5 for a certain distance, and then the stop block 302 is turned towards the cutter bar limiting portion 2 to lay the stop block 302 flat, and the cutter bar 4 is taken down from the cutter bar limiting portion 2, thereby completing the whole replacing process.
Example 2:
referring to fig. 5, unlike embodiment 1, a hoop device is hinged on a sliding block 301 of the movement limiting device. The hoop device comprises a first hoop 600 and a second hoop 601 which are semicircular. One end of the first hoop 600 is hinged to the sliding block 301, an installation groove is formed in the outer circumferential surface of the other end side of the first hoop 601 in the downward direction, a rotating shaft is arranged on the inner side wall opposite to the installation groove, and a T-shaped connecting block is sleeved on the rotating shaft and can rotate around the rotating shaft. The connecting block comprises a sleeve 602 sleeved on the rotating shaft, a first connecting rod 603 vertically arranged on the outer wall of the sleeve 602, and a second connecting rod 604 connected with the end side of the first connecting rod 603. In order to ensure the firmness of the fixed connection between the first hoop 600 and the second hoop device 601, the diameter of the first connecting rod 603 is smaller than the diameter of the second connecting rod 604. One end of the second anchor ear 601 is hinged to the slider 301, and a clamping groove 605 corresponding to the first connecting rod 603 and the second connecting rod 604 is disposed on the outer circumferential surface of the other end of the second anchor ear 601. As shown in fig. 6 and 7, when the knife bar 4 needs to be fixed, one end of the knife bar 4 is disposed in the position-limiting ring 201, the T-shaped handle 305 is rotated to make the slider 301 on the screw 300 move the hoop device to the end surface of the hoop device close to the position-limiting ring 201 to be attached to the end surface of the protruding ring 401 of the knife bar 4, and then the connecting block is rotated to clamp the first connecting rod 603 and the second connecting rod 604 in the clamping groove 605, so that the first hoop 600 and the second hoop 601 are connected to clamp the knife bar 4 between the position-limiting ring 201 and the hoop device. After the milling cutter 5 is replaced, the first connecting rod 603 and the second connecting rod 604 are transferred out of the clamping groove 605, so that the first hoop 600 and the second hoop 601 are separated, the first hoop 600 and the second hoop 601 are opened, and the cutter bar 4 is taken out of the limiting ring 201. In addition, in order to facilitate the connection block to be transferred out of the slot 605, a fixing block for facilitating holding by hand may be provided on an outer wall of the first connection rod 603 or the second connection rod 604, and the fixing block may protrude from the slot 605 when the connection block is engaged in the slot 605.
