Description

Technical Field

[0001] This utility model relates to the field of engraving equipment technology, specifically an engraving equipment for billboard production. Background Technology

[0002] As business competition intensifies, advertising, as the core carrier of brand communication and information transmission, is becoming increasingly diversified, with ever-increasing demands for production precision, efficiency, and personalization.

[0003] Traditional tool holders typically use bolts or tapered fittings to secure the cutting tools. When changing tools, tools such as wrenches and screwdrivers are needed to remove the fasteners, and each tool change typically takes 2-3 minutes. For complex billboard engraving that requires frequent switching between various types of tools such as milling cutters, V-cutters, and drilling cutters, the cumulative tool change time accounts for more than 30% of the total processing time, which seriously affects the efficiency of mass production.

[0004] After repeated disassembly, the bolts or tapered mating surfaces are prone to wear, which leads to an increase in the coaxiality deviation between the tool and the spindle. This results in problems such as rough edges and dimensional deviations in the engraved patterns, which has a significant impact, especially on high-precision billboard engraving.

[0005] Therefore, this utility model provides an advertising board manufacturing and engraving device to solve the above problems. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Adopting a mechanical linkage structure of "button-connecting rod-linkage push rod", pressing the button will simultaneously squeeze the elastic block through the push rod, causing it to disengage from the slot, realizing toolless insertion and removal of the tool. The time for a single tool change is greatly shortened, and the efficiency is greatly improved compared with the traditional method. It is especially suitable for complex billboard engraving with multiple alternating processes.

[0018] Three elastic blocks evenly distributed at 120° form a three-point positioning with the groove on the inner wall of the chuck body. Combined with the rigid connection between the keyway and the receiving part, it reduces the coaxiality error between the tool and the spindle output end. It can maintain the engraving accuracy even after multiple tool changes, solving the problem of accuracy decay caused by wear in traditional structures. Attached Figure Description

[0026] 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.

[0027] This utility model provides an advertising board engraving equipment, including a detachable tool holder 7 and a spiral protective cover 8. The machine tool body 1 is made of cast iron. A first lead screw 2 is horizontally fixed on both sides of the machine tool through bearing seats. One end of the first lead screw 2 is connected to a servo motor. The moving frame 3 is engaged with the first lead screw 2 through a lead screw nut at the bottom. A limit rod is installed at the bottom of the first lead screw 2 to ensure that the moving frame 3 moves smoothly along the X-axis. A second lead screw 4 is installed parallel to the crossbeam of the moving frame 3. One end of the second lead screw 4 is connected to another servo motor. The moving part body 501 of the moving part 5 is connected to the second lead screw 4 through a lead screw nut and moves along the Y-axis. A Z-axis lead screw is vertically installed inside the moving part body 501 and is connected to a servo motor through a gearbox. The connecting table 502 is connected to the Z-axis lead screw through a nut seat to realize vertical lifting.

[0028] The receiving part 6 on one side of the connecting table 502 has a square cavity structure. The main body 701 is installed inside through a keyway. The main body 701 and the receiving part 6 are radially fixed by two M8 bolts to prevent rotation and loosening. The spindle output end 702 inside the main body 701 is connected to the spindle motor of the equipment through a coupling. A tool mounting hole is opened at the bottom. The tool 703 can be selected as a milling cutter, V-cutting cutter, etc. according to the engraving requirements. After the shank diameter is inserted into the hole, the three elastic blocks 704 on the surface pop out in the natural state and are locked into the three grooves on the inner wall of the main body 701. The grooves are evenly distributed at 120°.

[0029] One end of the linkage rod 705 is attached to the elastic block 704, and the other end is fixed to the circular connecting plate of the connecting rod 706 by welding. A spring 707 is sleeved on the outside of the connecting rod 706. One end of the spring abuts against the inner wall of the card seat body 701, and the other end abuts against the connecting plate. The button 708 is fixed to the end of the connecting rod 706 by threaded connection. A limiting block 709 is embedded in the irregular groove with a depth of 10mm inside the card seat body 701, which is attached to the surface of the button 708 to prevent the button from falling off due to the elastic stress of the spring 707.

[0030] The outer side of the receiving part 6 has two pre-set M6 threaded holes. The protective cover body 801 is fixed to the receiving part 6 by two bolts 802. The inner wall of the protective cover body 801 is machined with a continuous right-hand spiral groove. When the tool rotates at high speed and drives the air flow, the starting end of the spiral groove matches the direction of the air swirl, ensuring that the dust can smoothly enter the spiral groove. The bottom of the cover is welded with an inclined dust collection port 803. The bottom of the dust collection port is connected to the conveying pipe 804 by a thread. The end of the conveying pipe is fitted with a dust collection bag 805, and the bag opening is tightened and fixed by an elastic rope.

[0031] Working principle: The receiving part 6 on one side of the connecting table 502 provides an installation reference for the card holder body 701. It is connected to the receiving part 6 through keyway to ensure that the card holder body 701 has no relative displacement when rotating at high speed. The spindle output end 702 inside the card holder body 701 receives the torque of the spindle motor through the coupling, which drives the tool 703 installed at the bottom to rotate at high speed, realizing the cutting and engraving of the billboard material.

[0032] In its natural state, three elastic blocks 704, distributed at 120° angles, pop out and engage with corresponding grooves on the inner wall of the main body 701 of the chuck. The cutting torque is transmitted through the interlocking of the convex and concave parts to prevent tool slippage. When a tool change is required, pressing the button 708 pushes the linkage rod 705 through the connecting rod 706 to compress the elastic blocks 704, causing them to retract and disengage from the grooves. At this time, the tool can be directly inserted or removed. After releasing the button, the elastic force of the spring 707 pushes the connecting rod 706 and the button to reset, and the elastic blocks 704 pop out again to engage the new tool. The limiting block 709 limits the button travel by adhering to the button 708 to prevent excessive pressing from damaging the components.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
