Description

Technical Field

[0001] This utility model relates to the field of toy processing technology, specifically a CNC punching machine for processing children's toys. Background Technology

[0002] Building blocks are typically cubic wooden solid toys, usually decorated with letters or pictures on each surface, allowing for different arrangements or building activities. Building blocks come in various styles, can develop children's intelligence, and can be assembled into houses, various animals, etc. After the wooden toy building blocks are cut and processed, holes need to be drilled on their outer surfaces to facilitate the subsequent installation of accessories or design.

[0003] In the toy manufacturing industry, when drilling holes in building blocks, the performance of the clamping mechanism directly affects production efficiency and ease of operation. Currently, the mainstream clamping methods are divided into manual clamping and electric clamping, but both have significant limitations. Taking the manual clamping mechanism as an example, the hole-drilling device for building block toys disclosed in patent number CN219748273U uses a throttle to drive the threaded rod to rotate inside the threaded sleeve, which drives the right-side clamping block and the right-side rubber pad to move inward to clamp the workpiece. However, this operation process is cumbersome and lengthy: before drilling, the throttle needs to be manually rotated repeatedly to adjust the position of the clamping block; after drilling, the threaded rod needs to be rotated in the opposite direction to reset the clamping block before the building block can be disassembled. This process not only consumes a lot of manpower and time, but the frequent manual adjustment is also prone to operational errors, affecting the positioning accuracy and drilling quality of the building block, making it difficult to meet the high-efficiency requirements of large-scale production. Although the electric clamping mechanism has improved the level of automation to a certain extent, its operational complexity has not been fundamentally improved. For example, the CNC punching machine for children's toys with patent number CN213703733U uses a third motor to drive the second threaded rod to rotate, causing the clamping plate to slide on the work platform. When using it, the operator needs to start the motor first to adjust the distance between the clamping plates, place the building blocks, and then start the motor again to complete the clamping action. After the punching is completed, the operator also needs to operate the motor to release the clamping plate. Throughout the process, the motor needs to be started and stopped repeatedly, which not only increases the number of operation steps but also reduces the stability and continuity of production. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a CNC punching machine for processing children's toys, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A CNC punching machine for processing children's toys, comprising a base, a fixing frame and a clamping seat on the top of the base, an installation box fixed to the upper back of the fixing frame, a pressing plate inside the installation box, and the top of the pressing plate being fixed to the upper interior of the installation box by a first spring, a normally open switch being provided at the lower interior of the installation box, an installation frame, a protective pad and a positioning rod fixed to the top of the clamping seat, an electromagnet fixed in the middle of the interior of the installation frame, and sliding connections on both sides of the interior of the installation frame. An adsorption block is provided, and a clamping arm is fixed to the back of the adsorption block. A second screw is provided on both sides of the clamping arm, and one end of the second screw is connected to the clamping block. The clamping arm slides in conjunction with a positioning rod. A second spring is sleeved on the outer surface of the positioning rod, and both ends of the second spring are fixed to the two sets of clamping arms respectively. A servo motor is installed on the top of the mounting frame, and a vertical lead screw is connected to the output end of the servo motor. A threaded bracket is threaded onto the outer surface of the vertical lead screw, and a top rod extending into the mounting box is fixed to the top of the threaded bracket. A dust collection assembly is provided on the back of the base.

[0006] Furthermore, a transverse frame is welded to the outer surface of the threaded frame, a transverse lead screw is installed inside the transverse frame, a mounting base is threaded to the outer surface of the transverse lead screw, a drive motor is installed on the outer surface of the mounting base, and a drill bit is installed at the output end of the drive motor.

[0007] By adopting the above technical solution, the staff can manually drive the horizontal lead screw to rotate, thereby causing the threaded mounting base to slide along the horizontal frame, thus realizing the horizontal position adjustment of the drive motor and drill bit on the mounting base; this structural design supports flexible adjustment of the drill bit position before drilling, and can accurately match the requirements of different batches and different hole positions of building blocks.

[0008] Furthermore, a guide rod is fixed to the inner side of the fixing frame, and the threaded frame and the guide rod are slidably engaged.

[0009] By adopting the above technical solution, during the process of the servo motor driving the vertical lead screw to lift the thread frame, the guide rod provides precise guidance and stable support for the thread frame; this design effectively avoids the tilting or shaking of the thread frame caused by uneven force, ensuring the positioning accuracy of the drill bit during drilling.

[0010] Furthermore, a sliding rod is fixed between the fixing frame and the base, and the clamping seat is slidably engaged with the sliding rod. A first screw is installed on the outer surface of the base, and one end of the first screw is movably connected to the clamping seat.

[0011] By adopting the above technical solution, the clamping seat can be driven to move along the slide bar by rotating the first screw; this structure realizes the flexible adjustment of the position of the clamping seat, and also achieves the purpose of adjusting the position of the building blocks, which is convenient for drilling holes at different positions of the building blocks.

[0012] Furthermore, the inner wall of the mounting box is fixed with a positioning rail, the pressing plate slides with the positioning rail, and a silicone pad is provided at the bottom of the pressing plate.

[0013] By adopting the above technical solution, it is ensured that the pressing plate moves accurately in the vertical direction under the action of the top rod, and the bottom silicone pad achieves flexible pressing of the normally open switch; the design eliminates the shaking of the pressing plate through the positioning rail, so that the closing accuracy of the internal contacts of the normally open switch reaches ±0.1mm.

[0014] Furthermore, the normally open switch is electrically connected to the electromagnet, and the positioning rod is provided with a damping layer.

[0015] By adopting the above technical solution, when the normally open switch is closed and the electromagnet is energized to attract the adsorption block, the clamping arm slides rapidly along the positioning rod. The damping layer (made of polyurethane material with a Shore hardness of 70A) dissipates kinetic energy through viscous friction, suppressing the sliding speed from 0.8m / s without damping to 0.3m / s. This reduces the contact impact force between the clamping block and the building block by 65%, avoiding surface damage to the workpiece or knocking the building block away due to rigid collision. After drilling is completed, the normally open switch is opened, and the magnetic field of the electromagnet begins to decay. The damping layer can prevent the clamping arm from rapidly resetting and causing impact damage, thereby achieving gradual release and extending the service life of mechanical parts.

[0016] Furthermore, the clamping blocks are provided in two sets, one side of each set of clamping blocks is V-shaped, and the inner side of each set of clamping blocks is provided with a rubber pad.

[0017] By adopting the above technical solution, the self-centering characteristics of the V-shaped surface and the high friction and high elasticity of the rubber are utilized to automatically adjust and firmly clamp different shaped blocks. It can accurately center cylindrical / square blocks and also has a certain compatibility with irregularly shaped blocks. The rubber pad not only enhances the clamping stability, but also buffers the impact during clamping and protects the surface of the blocks from wear.

[0018] Furthermore, the dust collection assembly includes a dust collection box, a fan is installed at the bottom of the dust collection box, an installation rail is fixed to the inner wall of the dust collection box, a filter element is installed on the inner side of the installation rail, a negative pressure pipe is connected to the top of the dust collection box, one end of the negative pressure pipe is connected to a dust suction nozzle, a sealing door is provided on the outer surface of the dust collection box, and the filter element is detached from the installation rail.

[0019] By adopting the above technical solution, the dust collection component draws air from the chip collection box to create negative pressure through the exhaust fan. The wood chips generated by drilling are sucked into the chip collection box through the dust nozzle and negative pressure pipe under the action of pressure difference. The filter element installed in the rail groove is used for efficient interception and filtration. The staff can quickly remove the filter element to clean the accumulated chips by opening the sealed door, which effectively avoids dust pollution. At the same time, the continuous airflow carries away the heat of the surrounding equipment, which significantly improves the efficiency of equipment cleaning and maintenance and the stability of electromagnet operation.

[0020] Furthermore, the positioning rod is movably connected to the clamping arm, and the top of the positioning rod is provided with a scale mark.

[0021] By adopting the above technical solution, the positioning rod and the clamping arm are connected by a sliding mechanism, providing precise guidance for the extension and retraction of the clamping arm. The scale on the top of the positioning rod clearly marks the dimensions in millimeters, allowing operators to read the data intuitively. When the spacing between the clamping blocks is adjusted by rotating the second screw, the clamping arm drives the movable rod to slide synchronously along the positioning rod, and the scale displays the spacing change in real time, achieving precise adjustment of ±0.1mm.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model comprises an electromagnet, an adsorption block, a clamping arm, a clamping block, a first spring, a second spring, a top rod, a pressing plate, and a normally open switch. During operation, the operator places the building block between two sets of clamping blocks. When the servo motor drives the vertical screw to rotate, the threaded frame moves the top rod downward, triggering the pressing plate to close the contacts inside the normally open switch under the action of the first spring. This energizes the electromagnet, generating magnetism, which in turn attracts the adsorption block. The adsorption block adheres to the electromagnet, and at this time, the adsorption block drives the clamping arm to overcome the resistance of the second spring, causing the clamping block to precisely hug the building block, thus completing the clamping operation. After drilling is completed, the threaded frame resets, causing the top rod to move upward, and the pressing plate automatically disengages from the normally open switch. The contacts inside the normally open switch then disconnect again. Simultaneously, the electromagnet is de-energized, and the second spring resets, driving the clamping arm, adsorption block, and clamping block to expand outward, thus releasing the clamping state of the building block. Compared with the traditional manual clamping method that requires repeated rotation of the threaded rod for adjustment, or the electric clamping method that requires multiple start-stop motor cycles, this solution is simple to operate and significantly improves production efficiency.

[0024] 2. This utility model, by incorporating a second screw and a positioning rod, allows the operator to drive a bidirectional threaded slider by rotating the second screw when drilling holes in different batches of building blocks. This drives two sets of clamping blocks to move synchronously in opposite directions or back-to-back along the guide rail, achieving a spacing adjustment range of ±50mm. The millimeter-level scale etched on the surface of the movable rod is aligned with the baseline of the clamping blocks in real time, ensuring an adjustment accuracy of ±0.1mm. This design, through a pre-positioning mechanism, allows the adsorption blocks to automatically adapt to different sizes of building blocks under a constant displacement stroke: when clamping small-sized building blocks (e.g., 20mm side length), the pre-adjusted spacing brings the initial position of the clamping blocks close to the workpiece, and the adsorption blocks only need a short stroke to complete the clamping after the electromagnet is energized; when facing large-sized building blocks (e.g., 80mm side length), the pre-adjusted spacing is increased, and the adsorption blocks still drive the clamping arms with the same stroke to achieve a stable encirclement. This method ensures the effective transmission of electromagnetic adsorption force (avoiding suction attenuation due to excessive stroke) and allows the same mechanism to cover workpieces of different sizes, improving the applicability of the fixture and drilling machine.

[0025] 3. This utility model uses a dust removal component. During the drilling process, the exhaust fan draws negative pressure into the chip collection box. Under negative pressure, the wood chips generated during drilling enter the chip collection box through the suction nozzle and the negative pressure pipe, and are eventually collected by the filter element. The staff can periodically disassemble the filter element to clean the wood chips, ensuring that no wood chips are collected. It also solves the problem of heat decay of the electromagnet during long-term operation through forced heat dissipation, achieving a dual technological breakthrough in dust removal and heat dissipation.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1: A CNC punching machine for processing children's toys, such as Figures 1-7As shown, the device includes a base 1, with a control panel on its outer surface. Both the servo motor and the drive motor are electrically connected to the control panel. A mounting bracket 2 and a clamping seat 13 are located on the top of the base 1. A mounting box 3 is fixed to the upper back of the mounting bracket 2. A pressing plate 19 is located inside the mounting box 3, and the top of the pressing plate 19 is fixed to the upper interior of the mounting box 3 by a first spring 20. A normally open switch 22 (brand: Donghai Nanbei, model: KW3A-16T0-B200-76, dustproof, mechanical life up to 2 million cycles) is located at the lower interior of the mounting box 3. The clamping seat... The top of the holder 13 is fixed with a mounting bracket 16, a protective pad 31, and a positioning rod 26. The protective pad 31 is made of rubber to prevent the drill bit from rigidly colliding with the holder 13 after drilling through. An electromagnet 23 is fixed in the middle of the mounting bracket 16. The normally open switch 22 is electrically connected to the electromagnet 23. The positioning rod 26 is provided with a damping layer. When the normally open switch 22 is closed, energizing the electromagnet 23 to attract the adsorption block 24, the clamping arm 25 slides rapidly along the positioning rod 26. The damping layer (made of polyurethane material with a Shore hardness of 70A) dissipates kinetic energy through viscous friction, reducing the sliding speed from 0 when there is no damping. The impact force of the clamping block 29 on the building block is reduced from 0.8 m / s to 0.3 m / s, thus reducing the contact impact force by 65% ​​and preventing surface damage to the workpiece or the building block from being knocked away by rigid collisions. After drilling is completed, the normally open switch 22 is disconnected, and the magnetic field of the electromagnet 23 begins to decay. The damping layer prevents the clamping arm 25 from being rapidly reset and causing impact damage, thereby achieving gradual release and extending the service life of mechanical parts. Furthermore, the mounting bracket 16 has suction blocks 24 slidably connected to its internal sides, and the clamping arm 25 is fixed to the back of the suction block 24. The clamping arm 25 has second screws 28 on both sides, with one end of the second screw 28 connected to... A clamping block 29 is attached, and the clamping arm 25 is slidably engaged with the positioning rod 26. The positioning rod 26 is movably connected to the clamping arm 25, and a scale mark is provided on the top of the positioning rod 26. The positioning rod 26 and the clamping arm 25 are slidably connected, providing precise guidance for the extension and retraction of the clamping arm 25. The scale mark (not shown in the figure) on the top of the positioning rod 26 clearly marks the size value in millimeters, allowing the operator to read the data intuitively. When the spacing of the clamping blocks 29 is adjusted by rotating the second screw 28, the clamping arm 25 drives the movable rod 30 to slide synchronously along the positioning rod 26, and the scale mark displays the spacing change in real time, achieving ±0.With a precise adjustment of 1mm, a second spring 27 is sleeved on the outer surface of the positioning rod 26, and the two ends of the second spring 27 are respectively fixed to two sets of clamping arms 25; a servo motor 4 is installed on the top of the fixing frame 2, and the output end of the servo motor 4 is connected to a vertical lead screw 5. A threaded bracket 6 is threadedly connected to the outer surface of the vertical lead screw 5. A top rod 18 extending into the interior of the mounting box 3 is fixed to the top of the threaded bracket 6. A transverse bracket 8 is welded to the outer surface of the threaded bracket 6. A transverse lead screw 9 is installed inside the transverse bracket 8. A mounting seat 10 is threadedly connected to the outer surface of the transverse lead screw 9. A drive motor 11 is installed on the outer surface of the mounting seat 10. A drill bit 12 is installed at the output end of the drive motor 11. The operator can manually drive the transverse lead screw 9 to rotate, thereby causing the threaded mounting seat 10 to slide along the transverse bracket 8, thus realizing the lateral position adjustment of the drive motor 11 and the drill bit 12 on the mounting seat 10. This structural design supports flexible adjustment of the drill bit 12 position before drilling, and can accurately match the requirements of different batches and different hole positions of building blocks.

[0037] See Figures 1-3 In the above embodiment, a guide rod 7 is fixed on the inner side of the fixing frame 2, and the threaded frame 6 slides with the guide rod 7. During the process of the servo motor 4 driving the vertical lead screw 5 to lift the threaded frame 6, the guide rod 7 provides precise guidance and stable support for the threaded frame 6. This design effectively avoids the tilting or shaking of the threaded frame 6 due to uneven force, ensuring the positioning accuracy of the drill bit 12 during drilling. A slide rod 15 is fixed between the fixing frame 2 and the base 1, and the clamping seat 13 slides with the slide rod 15. A first screw 14 is installed on the outer surface of the base 1, and one end of the first screw 14 is movably connected to the clamping seat 13. By rotating the first screw 14, the clamping seat 13 can be driven to translate along the slide rod 15. This structure realizes the flexible adjustment of the position of the clamping seat 13, and also achieves the purpose of adjusting the position of the building block, which is convenient for drilling holes in different positions of the building block.

[0038] See Figures 1-4 In the above embodiment, the inner wall of the mounting box 3 is fixed with a positioning rail 21, the pressing plate 19 is slidably engaged with the positioning rail 21, and a silicone pad is provided at the bottom of the pressing plate 19 to ensure that the pressing plate 19 moves accurately in the vertical direction under the action of the top rod 18, and the bottom silicone pad is used to achieve flexible pressing of the normally open switch 22; this design eliminates the shaking of the pressing plate 19 through the positioning rail 21, so that the closing accuracy of the internal contacts of the normally open switch 22 reaches ±0.1mm.

[0039] See Figure 1 , Figure 2 and Figure 7In the above embodiment, the clamping block 29 is provided in two sets. One side of the two sets of clamping blocks 29 is V-shaped, and the inner side of the two sets of clamping blocks 29 is provided with rubber pads. By utilizing the self-centering characteristics of the V-shaped surface and the high friction and high elasticity of the rubber, it automatically adjusts and firmly clamps building blocks of different shapes, achieving precise centering for cylindrical / square building blocks, and also having a certain compatibility with irregularly shaped building blocks. The rubber pads not only enhance the clamping stability, but also buffer the impact during clamping and protect the surface of the building blocks from wear.

[0040] Example 2: To facilitate the collection of sawdust and reduce the cleaning workload for staff, Example 2 is an improvement on Example 1. (See attached document for details.) Figures 2-3 The base 1 has a dust collection assembly 17 on its back. The dust collection assembly 17 includes a dust collection box 1701. A fan 1704 is installed at the bottom of the dust collection box 1701. A mounting rail 1705 is fixed to the inner wall of the dust collection box 1701, and a filter element 1706 is installed on the inner side of the mounting rail 1705. A negative pressure pipe 1702 is connected to the top of the dust collection box 1701, and a suction nozzle 1703 is connected to one end of the negative pressure pipe 1702. A sealing door is provided on the outer surface of the dust collection box 1701, and the filter element 1706 is connected to the mounting rail 1704. 05. Disassembly and Setup: The dust collection component 17 uses the exhaust fan 1704 to draw air from the chip collection box 1701, creating negative pressure. Wood chips generated during drilling are drawn into the chip collection box 1701 through the suction nozzle 1703 and negative pressure pipe 1702 under the pressure difference. The chips are then efficiently filtered by the filter element 1706 installed in the track groove. Workers can quickly remove the filter element 1706 by opening the sealed door to clean the accumulated chips, effectively preventing dust pollution. Simultaneously, the continuously flowing airflow removes heat from surrounding equipment, significantly improving equipment cleaning and maintenance efficiency and the operational stability of the electromagnet 23.

[0041] The implementation principle of this utility model is as follows: Before carrying out processing work, the operator first maintains the device and uses special grease to lubricate each screw and lead screw to ensure that the threaded pairs of the transmission components such as the first screw 14, the second screw 28, the vertical lead screw 5, and the transverse lead screw 9 are in good working condition, reducing frictional resistance and extending service life; at the same time, the wear of sliding components such as the positioning rail 21, the guide rod 7, and the slide rod 15 is checked, foreign objects are cleaned in time and lubricating oil is added to ensure smooth sliding of components such as the clamping seat 13 and the threaded frame 6;

[0042] During operation, the operator first rotates the two sets of second screws 28 according to the size of the building block, thereby driving the clamping blocks 29 on both sides to move along the slide bar 15. This, combined with the scale on the top of the positioning rod 26, achieves a ±0.1mm pre-adjustment of the spacing. Then, the building block is placed on the protective pad between the two sets of clamping blocks 29. The servo motor 4 drives the vertical lead screw 5 to rotate, causing the threaded frame 6 to move downward along the guide rod 7. The horizontal frame 8 moves downward accordingly. After the top rod 18 disengages from the pressing plate 19, the first spring 20 pushes the pressing plate 19 to move downward along the positioning rail 21. The bottom silicone pad triggers the normally open switch 22 to close, and the electromagnet 23 is energized to generate magnetic force to attract the adsorption block 24. This causes the clamping arm 25 to overcome the resistance of the second spring 27 and slide along the positioning rod 26, so that the rubber pad on the inner side of the "V" shaped clamping block 29 tightly adheres to the building block to complete the clamping.

[0043] After clamping, the operator can rotate the first screw 14 according to the drilling position, driving the clamping seat 13 to move along the slide bar 15 between the fixed frame 2 and the base 1 in the X-axis direction; at the same time, the servo motor 4 controls the vertical screw 5 (Y-axis) to rise and fall, and cooperates with the horizontal screw 9 (Z-axis) to drive the mounting seat 10 to slide along the horizontal frame 8, realizing the three-dimensional coordinate positioning of the drill bit 12 in the XYZ axis; after positioning, the exhaust fan 1704 starts to create negative pressure in the chip collection box 1701, and the drive motor 11 drives the drill bit 12 to rotate and drill, and the wood chips are intercepted and collected by the filter element 1706 through the dust suction nozzle 1703 and the negative pressure pipe 1702; after drilling, the operator controls the servo motor 4 to rotate in the opposite direction, the threaded frame 6 rises and resets along the vertical screw 5, the top rod 18 presses against the pressing plate 19 to disconnect the normally open switch 22, the electromagnet 23 loses its magnetism and releases the adsorption block 24, and the second spring 27 drives the clamping arm 25 to move the clamping block 29 to release the block, thus completing one block drilling process.
