Description

Technical Field

[0001] The utility model relates to a fixing device and a handicraft numerical control engraving machine thereof. Background Art

[0002] The CNC engraving machine for handicrafts is a precision processing equipment widely used in the handicraft production industry. It controls the movement of the tool through computer numerical control technology, performs fine engraving and cutting on various materials, and can produce complex and exquisite patterns and shapes. This equipment has greatly improved the efficiency and precision of handicraft production and has become an indispensable tool in modern handicraft production.

[0003] In the traditional CNC engraving process of handicrafts, the fixation of the workpiece is a key link, which directly affects the precision and quality of the engraving. At present, there are mainly the following ways to fix the base of handicrafts:

[0004] Manual fixture fixation: The operator needs to manually place the craft base on the engraving machine workbench, and then use a mechanical fixture or pressure plate to fix it. Although this method is simple and direct, it is time-consuming, and the fixing effect may vary due to human factors, affecting the engraving accuracy.

[0005] Vacuum adsorption fixation: Some high-end engraving machines use a vacuum adsorption system to fix the workpiece by creating negative pressure on the workbench. This method has a good fixing effect, but it has certain requirements on the material and shape of the workpiece, and the system is complex and costly.

[0006] Magnetic fixation: For metal craft bases, some engraving machines use electromagnetic or permanent magnetic devices for fixation. This method is easy to operate, but it is only suitable for specific materials and has a limited scope of application.

[0007] Adhesive fixation: Some small or special-shaped workpieces may need to be fixed to the workbench using temporary adhesives. Although this method can adapt to workpieces of various shapes, the fixing and cleaning process is cumbersome and may affect the surface quality of the workpiece.

[0008] Although these existing fixing methods have their own advantages, they all have certain limitations. They either require manual intervention, which affects production efficiency; or have limited scope of application; or are complicated to operate, which increases production costs. Especially in production lines with a high degree of automation, these fixing methods often become bottlenecks that restrict overall efficiency improvement.

[0009] In view of these problems, the present application proposes a fixing device and a CNC engraving machine for handicrafts. The handicrafts are clamped by an automated mechanical clamp, and no manual fixing clamp is required. The handicrafts are automatically clamped when the workpiece is moved in, thereby improving the fixing efficiency and reducing the labor cost. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0045] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0046] like Figure 1 As shown, a CNC engraving machine for handicrafts includes a frame 1. The frame 1 is provided with an automatic engraving mechanism 2 for engraving handicrafts, and the automatic engraving mechanism 2 is CNC controlled, which is a prior art and will not be described in detail here. The frame 1 is provided with a base 3 below the automatic engraving mechanism 2, and a workbench 4 is slidably connected to the base 3 via a guide rail. The bottom of the workbench 4 is driven to move by a motor or a cylinder, which is a prior art and will not be described in detail here.

[0047] The core technical solution of this application is as follows:

[0048] Example 1: Fixing device

[0049] like Figure 2 As shown, in order to solve the purpose of feeding the workpiece into the workbench 4 and automatically fixing it, the present application is provided with two driving wheels 5 arranged opposite to each other on one side of the base 3. A driving rod 6 is meshed in the middle of the two driving wheels 5. The driving rod 6 is fixedly connected to the workbench 4. When the workbench 4 slides, it can drive the driving rod 6 to slide in the horizontal direction.

[0050] The edge of the driving wheel 5 is fixedly connected with a swing rod 7. The swing rod 7 can be made of rubber material and has a certain elasticity.

[0051] As described above, when the workbench 4 moves toward the bottom of the automatic engraving mechanism 2 under the driving action of its motor or cylinder, it moves to the right side to the position as shown in FIG. Figure 1 In this process, the driving rod 6 is driven to move, driving the rocker bars 7 engaged on both sides to rotate, and finally the two rocker bars 7 are squeezed, positioned and clamped with the handicraft on the workbench 4, thereby fixing the handicraft.

[0052] Under the above setting, the craft is placed on the workbench 4, and then, when the workbench 4 moves under the automatic engraving mechanism 2, the swing rod 7 just squeezes the craft, and the swing rod 7 has a certain elasticity and can adapt to different shapes of craft bases 3. When the craft is automatically fed in, the craft is automatically fixed, thereby reducing labor costs and improving fixing efficiency.

[0053] After the fixing is completed, the automatic engraving mechanism 2 performs CNC engraving on the upper side of the handicraft to form a final handicraft product with a certain shape.

[0054] Example 2: Recovery Device

[0055] like Figure 3 As shown, in order to achieve the purpose of automatic recycling after the craftwork is engraved, the present application has a slide bar 8 fixedly connected to one side of the workbench 4. A gear 9 is meshed above the slide bar 8. An adsorption rod 10 is meshed above the gear 9. One end of the adsorption rod 10 has magnetic or adhesive properties. For metal crafts, magnetic materials can be used. For non-metal crafts, materials with certain self-adhesiveness such as silicone rubber can be used, or tape can be used.

[0056] Optimally, a connecting rod 11 is connected to the top of the adsorption rod 10. A bracket 12 is slidably connected to the top of the connecting rod 11. The bracket 12 is fixedly connected to the rack 1. A slider 13 is fixedly arranged on the top of the connecting rod 11. The slider 13 can slide on the bracket 12.

[0057] The corresponding craftwork to be engraved is placed on the workbench 4, which is driven by the motor to move to the bottom of the automatic engraving mechanism 2, fix the craftwork and then automatically engrave the craftwork. In this process, the slide bar 8 moves to the right, drives the gear 9 to rotate, and drives the adsorption rod 10 to move in the opposite direction to abut against the craftwork.

[0058] After the engraving is completed, the workbench 4 is reset. At this time, the suction rod 10 suctions the handicraft and makes the handicraft move in the opposite direction to the workbench 4, so that the suction rod 10 drives the handicraft to leave the workbench 4 to complete automatic recovery.

[0059] Under the above arrangement, the movement of the workbench 4 can drive the automatic recycling of the handicrafts, which reduces manual involvement, improves the efficiency of automatic recycling, eliminates the need for a robot for recycling, and reduces the purchase cost.

[0060] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
