Technical Field

[0001] This utility model relates to the technical field of drill bit fixing devices, specifically a support structure for machine tool drill bits that can be assembled quickly. Background Technology

[0002] The support structure for machine tool drill bits refers to the key component used to support and fix the drill bit, ensuring its stable and accurate operation during machining. This support structure is crucial for ensuring drilling quality, improving machining efficiency, and guaranteeing operational safety. However, existing equipment still has certain shortcomings, such as:

[0003] Application CN202222526151.3, entitled "A Lathe Drill Bit Fixing Mechanism," includes a mounting base and a mounting plate fixed to the top of the mounting base. The mounting base has a placement groove at its bottom, a top plate at the top of the inner cavity of the placement groove, a spring at the top of the top plate, a limit ring at the bottom of the top plate, a drill bit inserted into the middle of the limit ring, and a fixing hole at the top of the drill bit. However, this device requires manual insertion and removal of a strip when changing the drill bit, which prevents quick drill bit replacement, increases the time cost of replacement, reduces work efficiency, and fails to meet usage requirements. Therefore, a quick-assembly support structure for machine tool drill bits is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a quick-assembly support structure for machine tool drill bits, in order to solve the problem mentioned in the background art that existing machine tool drill bit support structures cannot achieve quick drill bit replacement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a machine tool body, within which a clamping chamber is fixedly connected to the lower end face of the main spindle, and a drive motor is fixedly connected to the center of the top surface of the clamping chamber; a block is fixedly connected to the shaft end of the drive motor, and a curved strip is rotatably connected to the upper end face of the block; the curved strip is symmetrically arranged about the center of the drive motor, and a device column is rotatably connected to the tail end of the curved strip; the lower end face of the device column penetrates the lower end face of the clamping chamber, and a sliding groove corresponding to the device column is provided on the lower end face of the clamping chamber; an insertion slot is provided on the lower end face of the clamping chamber; a slide rail assembly is fixedly connected to the top surface of the clamping chamber, and the device column is slidably connected to the clamping chamber through the slide rail assembly; a primary clamping block is fixedly connected to the inner end face of the device column.

[0006] The above technical solution facilitates the rapid clamping and disassembly of drill bits.

[0007] As a preferred embodiment of this utility model, a second-level clamping block is rotatably connected to the inner end face of the first-level clamping block, and a third-level clamping block is rotatably connected to the inner end face of the second-level clamping block.

[0008] The above technical solution facilitates the stable fixing of drill bits of different shapes, thereby improving the stability of the drill bits.

[0009] As a preferred embodiment of this utility model, the three-stage clamping blocks are symmetrically arranged about the center of the two-stage clamping blocks.

[0010] The above technical solution facilitates the stable clamping of the drill bit from all directions, avoids shaking during high-speed rotation machining, and improves machining accuracy and efficiency.

[0011] As a preferred embodiment of this utility model, a fourth-level clamping block is rotatably connected to the inner end face of the third-level clamping block, and the fourth-level clamping block is symmetrically arranged about the center of the third-level clamping block.

[0012] By adopting the above technical solution, the drill bit is prevented from shifting due to uneven force during processing, thereby further improving the processing accuracy and stability of the drill bit.

[0013] As a preferred embodiment of this utility model, a traction bar is rotatably connected to the upper end face of the block, and the traction bar is circumferentially arranged about the center of the block; a clamping column is rotatably connected to the tail end of the traction bar, and the upper end face of the clamping column is slidably connected to the top surface of the clamping chamber.

[0014] The above technical solution facilitates rapid positioning and clamping of the drill bit.

[0015] As a preferred embodiment of this utility model, the lower end face of each clamping column penetrates the lower end face of the clamping chamber, and the lower end face of the clamping chamber is provided with a sliding groove corresponding to the clamping column; a clamping block is fixedly connected to the lower end face of the clamping column, and an anti-slip pad is fixedly connected to the inner end face of the clamping block.

[0016] The above technical solution facilitates further enhancement of the clamping effect, ensuring that the drill bit will not fall off due to external forces during processing.

[0017] As a preferred embodiment of this utility model, a loading block is fixedly connected to the inner end face of the equipment column, and slots are evenly arranged in the loading block; a reset spring is fixedly connected to the left end face of the slot, and a limit block is fixedly connected to the right end face of the reset spring; the right end of the limit block penetrates the right end face of the loading block, and the limit block and the right end face of the loading block are slidably connected.

[0018] The above technical solution facilitates the stable loading of the drill bit. Through the elastic action of the return spring, the limiting block can fit tightly against the drill bit, effectively preventing the drill bit from shaking during processing and further improving the stability and accuracy of processing.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the device, through the setting of clamping column, clamping chamber, slide groove, clamping block and anti-slip pad, can realize the rapid clamping of drill bit. It is not only simple and convenient to operate, but also greatly improves the stability and firmness of clamping, and effectively prevents the drill bit from shaking during processing, further improving the stability and accuracy of processing, thereby ensuring processing quality and efficiency.

[0020] 1. Place the drill bit tail end against the slot on the bottom of the clamping chamber, then start the drive motor. The drive motor drives the block to rotate, and the block pulls the equipment column to move in opposite directions through the curved strip and slide rail assembly until the fourth-stage clamping block is firmly against the drill bit column.

[0021] 2. Through the mutual rotational connection between the clamping blocks at each level, the four-level clamping blocks can adaptively adjust their position according to the size of the drill bit diameter, ensuring the tightness and stability of the clamping.

[0022] 3. When the limiting block contacts the drill bit body, the limiting block compresses the return spring inside the loading block. The return spring deforms under force, which in turn provides a thrust to the limiting block in the direction of the drill bit body, so that the limiting block fits tightly against the outer wall of the drill bit body, achieving a stable clamping of the drill bit. This design not only enhances the stability of clamping, but also ensures the safety of the drill bit during processing, effectively avoiding processing errors or accidents caused by drill bit shaking.

[0023] 4. The slide rail assembly and the groove design in the clamping chamber enable the equipment column to slide stably in the clamping chamber, effectively reducing errors caused by poor sliding, thereby extending the service life of the entire device and improving work efficiency.

[0024] 5. By using clamping posts circumferentially positioned around the center of the drive motor, the drill bit body can be stably clamped in multiple directions, ensuring high-precision positioning of the drill bit during processing and effectively improving processing quality and efficiency.
