A drilling device for processing wooden toys for children

Abstract

This utility model discloses a drilling device for processing children's wooden toys, belonging to the field of toy processing. The device includes two annular frames slidably mounted on the surface of a processing frame. Several clamping rods are detachably mounted on the surface of each annular frame, allowing the number of clamping rods to be increased or decreased according to the fixing method of the triangular wooden toy. The number of clamping rods can also be adjusted according to the shape of the wooden toy, allowing for clamping of more shapes of wooden toys. The clamping rods are rotatable relative to the annular frames, and extension rods are slidably connected inside the clamping rods. The ends of the extension rods are rotatably connected to clamping blocks, allowing for multi-level adjustment of the clamping blocks relative to the annular frames. This ensures that the clamping blocks can make large-area contact with the wooden toy during clamping, guaranteeing a good clamping effect. By using clamping blocks at different angles, three sides of the triangular wooden toy can be contacted simultaneously. Furthermore, the position of the multiple clamping blocks can limit the position of the triangular wooden toy relative to the processing frame, preventing it from shifting during drilling.

Description

Technical Field

[0001] This utility model relates to the field of toy processing, and in particular to a drilling device for processing children's wooden toys. Background Technology

[0002] Wooden toys are children's toys made primarily of natural or synthetic wood through processes such as cutting, carving, polishing, and painting. Wooden toys come in a variety of shapes, including triangular, bowl-shaped, and animal-like forms.

[0003] The reference patent title is: A rapid drilling device for processing wooden toys (Patent Publication No.: CN218195727U). It uses two clamping units located above a base plate to clamp irregular toys. Each clamping unit includes a mounting frame, a first support, a first slider, a second support, a second slider, a slide rail, a protrusion, an anti-slip pad, a first magnet, and a second magnet. The protrusion and anti-slip pad can rotate within the support, which in turn rotates within the mounting frame. This multiple rotations allow the protrusion to fully conform to the surface of the irregular toy and press firmly against it. This not only enables the clamping and fixing of irregularly shaped workpieces but also provides multiple fixing points, each adjustable individually, ensuring effective clamping, facilitating drilling, and improving work efficiency and safety.

[0004] However, the following problems exist when implementing the above technical solutions: the above drilling device is difficult to stably clamp some triangular wooden toys. When clamping triangular wooden toys, the above device can only fit the two edges of the toy. However, since it is difficult to fix the position when the triangular shape only fits the two sides, it is difficult to avoid continuous upward or downward movement during the clamping process, making it difficult to ensure the clamping stability effect, and thus it is difficult to drill holes stably. If the corner of the triangular wooden toy is clamped directly, the third side of the triangular wooden toy is not effectively fixed, and its position and angle can change.

[0005] In summary, this utility model proposes a drilling device for processing children's wooden toys. Utility Model Content

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0029] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a drilling device for processing children's wooden toys, including a processing frame 1, wherein a clamping mechanism is provided on the surface of the processing frame 1, and the clamping mechanism includes:

[0030] Two ring frames 2 are slidably disposed inside the processing frame 1, and the two ring frames 2 are symmetrically arranged relative to the processing frame 1.

[0031] A plurality of clamping rods 3 are fixedly disposed inside the annular frame 2. One end of each clamping rod 3 is rotatably connected to a clamping column 4. A fixing component is disposed between the clamping column 4 and the annular frame 2. The fixing component is slidably disposed inside the clamping column 4. A limiting component is disposed between the clamping column 4 and the clamping rod 3. The limiting component is slidably disposed inside the clamping rod 3.

The positioning component is slidably disposed inside the extension rod 21. A clamping block 5 is rotatably connected to the end of the extension rod 21 away from the clamping column 4.

[0032] In summary, the present invention provides a drilling device for processing children's wooden toys, comprising two annular frames 2 slidably disposed on the surface of a processing frame 1. Several clamping rods 3 are detachably disposed on the surface of each annular frame 2, allowing the number of clamping rods 3 to be increased or decreased according to the fixing method of the triangular wooden toy. The number of clamping rods 3 can also be adjusted according to the shape of the wooden toy, enabling clamping of wooden toys of various shapes. Furthermore, the clamping rods 3 are rotatable relative to the annular frames 2, and an extension rod 21 is slidably connected inside each clamping rod 3. The end of the extension rod 21 is rotatably connected to a clamping block 5, allowing the clamping block 5 to be adjusted in multiple stages relative to the annular frames 2. This ensures that the clamping block 5 can make large-area contact with the wooden toy during clamping, guaranteeing the clamping effect.

[0035] In a further embodiment, two arc-shaped grooves 9 are formed on the surface of the ring frame 2. The two arc-shaped grooves 9 are symmetrically arranged relative to the fixed groove and are located at both ends of the fixed groove.

By controlling the position of the limiting rod 11, the limiting rod 11 can be made to contact the rotating groove or the limiting grooves 10. When the limiting rod 11 contacts the limiting grooves 10, the position of the clamping post 4 relative to the clamping rod 3 can be limited.

[0037] In some specific implementations, the positioning component includes a plurality of positioning grooves 13 formed on the surface of the clamping rod 3, and a positioning tooth 12 is slidably connected inside the extension rod 21. The positioning tooth 12 is adapted to the positioning groove 13, and a positioning spring 14 is fixedly connected between the positioning tooth 12 and the extension rod 21. By adjusting the position of the positioning tooth 12, the positioning tooth 12 can be made to contact the positioning groove 13, thereby limiting the position of the extension rod 21.

[0038] In a further embodiment, the extension rod 21 is internally threaded with an operating rod 15, the operating rod 15 having an isosceles trapezoidal cross-section, and the operating rod 15 engaging with the positioning teeth 12;

Next, press the fixing rod 8 to place the extrusion column into the fixing groove. After the clamping rod 3 slides to the appropriate position, release the fixing rod 8. The fixing rod 8 will return to its original position under the action of the fixing spring and contact the fixing groove. Then, pull the extension rod 21 to make the clamping block 5 contact the wooden toy. Rotate the limiting rod 11 until it contacts the limiting groove 10. Then, rotate the operating rod 15 to make the positioning tooth 12 slide into the positioning groove 13. Pull the operating block 18 to make it disengage from the clamping groove 17. Rotate the clamping block 5 to make it contact the wooden toy over a large area. Release the operating block 18, which will return to its original position under the action of the operating spring 19. Multiple clamping rods 3 are set on the surface of the ring frame 2 to fix the position of the wooden toy.
