Example 1

Referring to fig. 1-2, the present embodiment provides a tool bit fixture for numerical control machining, including a fixture body 1, one end of the fixture body 1 is provided with a mounting cavity 9 for mounting a tool bit 10, a first movable cavity 2 is arranged inside the fixture body 1, one side of the first movable cavity 2 is communicated with a second movable cavity 3, a top block 5 is arranged inside the first movable cavity 2, one side of the top block 5 is fixedly connected with a locking rod 4, and one end of the locking rod 4, which is far away from the top block 5, extends from the second movable cavity 3 to the outside of the fixture body 1; the inside still activity of anchor clamps body 1 is provided with bracing piece 6, 6 one end of bracing piece stretches into first activity chamber 2, and the other end stretches into

installation cavity

9, 9 inner walls elasticity of installation cavity are provided with inserted bar 11, slot 12 corresponding with inserted bar 11 is seted up to tool bit 10 side.

When installing tool bit 10, insert installation cavity 9 with tool bit 10 in, because inserted bar 11 elasticity sets up at installation cavity 9 inner wall, when tool bit 10 just inserted installation cavity 9 inside, inserted bar 11 contracts, when tool bit 10 tip crosses inserted bar 11 and slot 12 and inserted bar 11 correspond, inserted bar 11 inserts in slot 12, fix a position tool bit 10, at this moment, drive dog 5 through check lock lever 4 and advance to first activity chamber 2 inside, and then drive bracing piece 6 and move to installation cavity 9 inside, support tool bit 10 tip, cooperation inserted bar 11 realizes tool bit 10 axial direction's fixed.

Specifically, the check lock lever 4 and the 3 screw-thread fit in the second movable cavity drive the stop 5 to move towards the first movable cavity 2 when the check lock lever 4 drives the stop, and the check lock lever 4 and the stop 5 are limited by the screw-thread fit of the check lock lever 4 and the second movable cavity 3, so that the tool bit 10 is prevented from being impacted when a workpiece is machined, the check lock lever 4 and the stop 5 move reversely, and the stability of the tool bit 10 is influenced.

Specifically, the side of the support rod 6 is fixedly provided with a limiting block 8, the fixture body 1 is internally provided with a sliding groove 7, and the limiting block 8 extends into the sliding groove 7 and is in sliding fit with the sliding groove 7.

Through the sliding fit of stopper 8 and spout 7, still can carry on spacingly to bracing piece 6 when guaranteeing that bracing piece 6 removes steadily, avoid when anchor clamps body 1 does not install tool bit 10, bracing piece 6 follows 9 roll-off anchor clamps bodies of installation cavity 1.

Specifically, the third activity chamber 13 that extends to the inside of anchor clamps body 1 is seted up to installation cavity 9 inner wall, inserted bar 11 sets up in third activity chamber 13, and the one end fixedly connected with pull rod 15 of installation cavity 9 is kept away from to inserted bar 11, the one end that inserted bar 11 was kept away from to pull rod 15 extends to the outside of anchor clamps body 1, the inside spring 14 that is used for supporting inserted bar 11 that still is provided with of third activity chamber 13.

When the end part of the cutter head 10 is inserted into the mounting cavity 9, the inserted bar 11 is pushed to the inside of the third movable cavity 13 of the box through the end part of the cutter head 10, the spring 14 is pressed, and when the cutter head 10 moves to the position corresponding to the position of the inserted bar 11 in the slot 12, the spring 14 supports the inserted bar 11, so that the inserted bar 11 extends into the slot 12, and the lateral positioning of the cutter head 10 is completed; when the tool bit 10 needs to be disassembled, the pull rod 15 is pulled to the outside of the clamp body 1, the pull rod 15 drives the inserted bar 11 to be separated from the slot 12, and the tool bit 10 is pulled out.

The working principle of the embodiment is as follows: when installing tool bit 10, insert installation cavity 9 with tool bit 10 in, because inserted bar 11 elasticity sets up at installation cavity 9 inner wall, when tool bit 10 just inserted installation cavity 9 inside, inserted bar 11 contracts, when tool bit 10 tip crosses inserted bar 11 and slot 12 and inserted bar 11 correspond, inserted bar 11 inserts in slot 12, fix a position tool bit 10, at this moment, drive dog 5 through check lock lever 4 and advance to first activity chamber 2 inside, and then drive bracing piece 6 and move to installation cavity 9 inside, support tool bit 10 tip, cooperation inserted bar 11 realizes tool bit 10 axial direction's fixed.

When the check block 5 is driven to move towards the inside of the first movable cavity 2 by the locking rod 4, the locking rod 4 and the check block 5 are in threaded fit with the second movable cavity 3, so that the limiting effect is achieved on the locking rod 4 and the check block 5, the tool bit 10 is prevented from being impacted when a workpiece is machined, the locking rod 4 and the check block 5 move reversely, and the stability of the tool bit 10 is affected.

When the end of the tool bit 10 is inserted into the mounting cavity 9, the end of the tool bit 10 pushes the inserted bar 11 to the third movable cavity 13, the spring 14 is pressed, and when the tool bit 10 moves to the slot 12 to correspond to the position of the inserted bar 11, the spring 14 supports the inserted bar 11, so that the inserted bar 11 extends into the slot 12, and the lateral positioning of the tool bit 10 is completed.

Example 2

Referring to fig. 1 and fig. 3-4, in the present embodiment, compared with embodiment 1, an extension cylinder 17 is installed on a side wall of a clamp body 1, the pull rod 15 penetrates through the extension cylinder 17, a baffle 18 and a locking sleeve 16 are fixedly arranged on the pull rod 15, the baffle 18 is located between the locking sleeve 17 and the extension cylinder 16, an inner wall of the locking sleeve 16 is provided with an inner thread, and an outer thread adapted to the inner thread is arranged outside the extension cylinder 17.

When the inserted bar 11 is in a matching state with the slot 12, the baffle 18 is just attached to the side surface of the extension cylinder 17, and at the moment, the locking sleeve 16 is in threaded fit with the extension cylinder 17, so that the baffle 18 is tightly pressed on the side surface of the extension cylinder 17, and the inserted bar 11 is prevented from shaking due to the transverse vibration from the tool bit 10.
