Description

Technical Field

[0001] This utility model relates to the field of drill bit replacement technology, specifically a detachable drill bit replacement device for a drilling machine. Background Technology

[0002] In the field of machining, drilling machines are commonly used hole-making equipment, and their drill bits need to be frequently changed according to processing requirements. Traditional drilling machines are usually equipped with a single drill bit clamping device, requiring operators to manually remove and install drill bits. In batch processing or multi-stage operations, it is often necessary to prepare multiple sizes of drill bits and repeatedly change them. To improve production efficiency, some processing facilities use pre-loaded spare drill bits for quick access to the required bits.

[0003] Currently, common drill bit replacement devices typically use a simple slot-type structure to store drill bits, lacking an effective clamping mechanism. During the storage process, the drill bits are prone to loosening or even falling off due to vibration or movement, which may also cause damage or loss, increasing the cost of use and the difficulty of maintenance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A detachable drill bit replacement device for a drilling machine includes a replacement box 1. Fixing frames 2 are detachably installed at both ends of the back of the replacement box 1. A height adjustment mechanism is provided between the fixing frames 2 and the replacement box 1. The height adjustment mechanism includes positioning holes 5. Several positioning holes 5 are sequentially opened from top to bottom in the middle of the fixing frame 2. Fixing blocks 6 are fixedly connected to both the upper and lower ends of the replacement box 1. Bolts 7 are threadedly connected between the fixing blocks 6 and the positioning holes 5.

[0026] In this embodiment, by using the positioning hole 5 in the height adjustment mechanism to cooperate with the fixing block 6, the installation height of the replacement box 1 can be adjusted according to different drilling machine models, ensuring the precise alignment of the device with the drilling machine spindle and optimizing the ease of operation.

[0027] like Figure 1 As shown, horizontal plates 3 are fixedly installed at the upper and lower ends of the two fixed frames 2. A fixing mechanism is provided on the side of the fixed frame 2 away from the replacement box 1. The fixing mechanism includes a screw 8. The screw 8 is movably installed between the middle of the two horizontal plates 3 through a bearing. A crank 9 is movably installed in the middle of the top horizontal plate 3. The crank 9 is coaxially connected to the screw 8. A transverse movable clamping plate 10 is movably installed on the back of the two fixed frames 2. The extended end of the back of the movable clamping plate 10 is threadedly connected to the screw 8. A fixed clamping plate 11 is fixedly connected to the back of the bottom horizontal plate 3.

[0028] In this embodiment, the movable clamping plate 10 driven by the lead screw 8 and the fixed clamping plate 11 form a clamping mechanism, which can be firmly fixed to the edge of the drill press base, preventing the device from shifting during replacement, ensuring operational stability, and facilitating disassembly and assembly.

[0029] like Figure 2 and Figure 4As shown, several storage slots 4 are arranged side by side inside the replacement box 1. A clamping mechanism is movably installed inside the storage slot 4. The clamping mechanism includes a clamping cylinder 12. The clamping cylinder 12 is movably installed inside the storage slot 4. A clearance slot 13 is provided on both sides of the inner wall of the clamping cylinder 12. A vertical elastic clamping strip 14 is fixedly connected to the bottom end of the clearance slot 13. An arc surface 15 is provided at the upper end of the elastic clamping strip 14. A top rod 16 is fixedly connected to the bottom end of the clamping cylinder 12. The bottom end of the top rod 16 penetrates the replacement box 1 and is located outside the lower part of the replacement box 1.

[0030] In this embodiment, by setting a clamping cylinder 12 with elastic clamping strips 14 and arc surface 15, it can automatically clamp when the drill bit body 17 is inserted, effectively preventing the drill bit body 17 from loosening and falling off due to vibration or movement during storage, reducing the risk of drill bit damage and loss. The through-type design of the push rod 16 allows the operator to push the drill bit body 17 out of the storage slot 4 simply by pushing it upwards, simplifying the steps of taking out and putting in the drill bit body 17 and significantly improving the efficiency of drill bit replacement.

[0031] Working principle: First, the screw 8 is rotated by the crank handle 9, causing the movable clamping plate 10 to move axially along the screw 8. This clamps the edge of the drill base with the fixed clamping plate 11, thus fixing the device and facilitating disassembly later. Then, the height adjustment mechanism is adjusted according to the height of the drill press. The fixing block 6 is aligned with the positioning hole 5 at the required height, and the bolt 7 is screwed in to fix the position of the replacement box 1. The operator inserts the drill bit body 17 to be replaced into the clamping sleeve 12. When the drill bit body 17 is pressed down, the elastic clamping strips 14 on both sides are squeezed outward by the arc surface 15, allowing the drill bit to smoothly enter the clamping sleeve 12. After the elastic clamping strips 14 rebound, they clamp the drill bit. When it is necessary to remove the drill bit body 17, the push rod 16 is pushed upward to raise the clamping sleeve 12, pushing the drill bit body 17 out of the storage slot 4 for the operator to retrieve. When replacing, the worker only needs to push out the required drill bit body 17, remove it, and then install it into the drill press spindle to complete the replacement.
