Description

Technical Field

[0001] This utility model relates to the field of wooden toys, and in particular to a grooved device for the side of a wooden toy cylinder. Background Technology

[0002] Wooden toys are entertainment and educational products for children or adults, made primarily from natural wood through processes such as cutting, sanding, splicing, and coloring.

[0003] The grooves on the sides of cylindrical wooden toys are significant. They facilitate the splicing and assembly of parts, allowing different parts to interlock and create various shapes. They also reduce weight and enhance structural stability while ensuring overall strength.

[0004] Currently, when grooving the sides of cylindrical wooden toys, the midpoints of the top and bottom ends of the cylindrical wooden toy are often fixed, and the grooving is performed while the toy is rotated. However, when fixing the cylindrical wooden toy, especially for some thin cylindrical wooden toys, the thinness makes it difficult to make contact with the side of the toy if a fixing component is added to the side, thus making it difficult to align the midpoint with the rotating shaft of the grooving device.

[0034] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a cylindrical side grooving device for wooden toys, comprising a base plate 1, a bracket 2 fixedly connected to the upper surface of the base plate 1, the bracket 2 being L-shaped, a worktable 3 fixedly connected to the upper surface of the base plate 1, the worktable 3 being cylindrical, an alignment mechanism 4 being provided inside the worktable 3, the alignment mechanism 4 including a turntable 41, the turntable 41 being cylindrical, the outer wall of the turntable 41 being rotatably connected to the inner wall of the worktable 3, a control groove 42 being arc-shaped on the inner wall of the turntable 41, and a positioning rod 43 being provided inside the control groove 42. The positioning rod 43 is cylindrical in shape and has a smooth outer wall. A height control plate 44 is fixedly connected to the lower end of the positioning rod 43. The diameter of the height control plate 44 is larger than the diameter of the positioning rod 43. A slide rod 45 is slidably connected to the inner wall of the turntable 41. A limit groove 47 is opened on the upper surface of the worktable 3. The limit groove 47 is straight. A push groove 48 is opened on the side of the worktable 3. The push groove 48 is arc-shaped. A control ring 49 is fixedly connected to the outer wall of the turntable 41. By setting the control ring 49, it is ensured that the operator can rotate the turntable 41 by pushing the control ring 49.

[0035] Reference Figures 1-3The lower surface of the bracket 2 is provided with a fixing mechanism 5, which includes a rotating plate 51. The upper surface of the rotating plate 51 is provided with a rubber coating that fits against the outer wall of the wooden toy. The lower surface of the rotating plate 51 is rotatably connected to the upper end of the support block 72. The fixing mechanism 5 also includes an electric telescopic rod 52. The electric telescopic rod 52 ensures that the device can fix the axis of the cylindrical wooden toy in the vertical direction. The electric telescopic rod 52 is located inside the bracket 2. A clamping plate 53 is fixedly connected to the lower surface of the electric telescopic rod 52. The clamping plate 53 is used to fix the upper surface of the cylindrical wooden toy. A servo motor 8 is fixedly connected to the inner side of the bracket 2. The output shaft of the servo motor 8 is fixedly connected to the upper surface of the electric telescopic rod 52. The servo motor 8 is used to drive the clamping plate 53, the rotating plate 51 and the cylindrical wooden toy to rotate together.

[0036] Reference Figure 1 , Figure 2 and Figure 6 The bracket 2 has a grooving mechanism 6 on its inner side. The grooving mechanism 6 includes a linear motor 61, which is fixedly installed on the inner side of the bracket 2. The moving part of the linear motor 61 moves up and down. The moving part of the linear motor 61 is fixedly connected to an electric push rod 62. The output shaft of the electric push rod 62 is fixedly connected to a mounting plate 63. A grooving knife 64 is fixedly connected to the end of the mounting plate 63 away from the electric push rod 62. The grooving knife 64 is used to groove the side of the wooden toy. The setting of the electric push rod 62 ensures that the distance between the grooving knife 64 and the outer wall of the cylindrical wooden toy is adjustable. A dust collection box 65 is fixedly connected to the outer wall of the mounting plate 63 away from the electric push rod 62, below the grooving knife 64. The dust collection box 65 is used to collect the debris generated during the grooving process.

[0037] Reference Figure 2 , Figure 3 and Figure 5The workbench 3 is internally equipped with a reset mechanism 7, which includes a pneumatic pipe 71. The inner wall of the pneumatic pipe 71 has two cylindrical grooves, with the top view area of ​​the upper cylindrical groove being more than twice the top view area of ​​the lower cylindrical groove. A support block 72 is piston-connected to the inner wall of the pneumatic pipe 71, and a moving block 74 is also piston-connected to the inner wall of the pneumatic pipe 71. By comparing the top view areas of the grooves in the pneumatic pipe 71, it is ensured that when the support block 72 moves downwards, the moving block 74 moves at least twice the distance of the support block 72. A rotating plate 75 is rotatably connected to the lower surface. The sliding rod 45 ensures that the rotating plate 75 can rotate synchronously with the turntable 41 when it rotates. The lower end of the sliding rod 45 is fixedly connected to the upper surface of the rotating plate 75. An adjustment groove 46 is fixedly connected to the upper surface of the rotating plate 75. The curvature of the adjustment groove 46 is the same as that of the control groove 42. The upper width of the adjustment groove 46 is the same as that of the control groove 42. The lower width of the adjustment groove 46 is wider than that of the control groove 42. A control block 76 is fixedly connected to the lower surface of the rotating plate 75. The control block 76 is cylindrical in shape.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The inner wall of the air pressure pipe 71 is elastically connected to the bottom end of the support block 72 via a spring 73. One end of the spring 73 is fixedly connected to the inner wall of the air pressure pipe 71, and the other end of the spring 73 is fixedly connected to the bottom end of the support block 72. The elastic force of the spring 73 is greater than the sum of the weights of the rotating plate 75 and the control block 76. The outer wall of the control block 76 has a reset groove 77, a rotating groove 78, and a moving groove 79. The reset groove 77 is spiral in shape. This spiral design ensures that when its inner wall is subjected to an upward force, it can drive the control block 76 under the action of the force. Block 76 rotates, and the rotating groove 78 is arc-shaped. The arc shape ensures that when the control ball 711 is in this position, the control block 76 can rotate normally. The reset groove 77 is located above the rotating groove 78. The upper part of the moving groove 79 is connected to the reset groove 77, and the lower part of the moving groove 79 is connected to the rotating groove 78. The moving groove 79 ensures that no matter what position the control ball 711 is in the rotating groove 78, it can move upward and eventually enter the interior of the reset groove 77. The inner wall of the worktable 3 is fixedly connected to the control tube 710, and the inner wall of the control tube 710 is fixedly connected to the control ball 711.

[0039] Working principle: When using it, the staff first place the cylindrical wooden toy that needs to be slotted on the side on the top of the rotating plate 51.

[0040] Subsequently, the staff pushed the control ring 49, and after the control ring 49 was moved by the force, it caused the turntable 41 to rotate.

[0041] Since the positioning rod 43 is inside the limiting groove 47, the positioning rod 43 can only move horizontally along the limiting groove 47. Since the positioning rod 43 is also inside the control groove 42, after the turntable 41 rotates, the positioning rod 43 moves towards the axis of the turntable 41 due to the push of the inner wall of the control groove 42 on its outer wall.

[0042] When the positioning rod 43 moves to contact the cylindrical wooden toy, since the wooden toy has room to move, the positioning rod 43 pushes the wooden toy, causing the wooden toy to move synchronously with it.

[0043] Once all the positioning rods 43 are in contact with the outer wall of the wooden toy, there is no room for the wooden toy to move. Therefore, the operator cannot continue to push the control ring 49. However, under the combined action of multiple positioning rods 43, the axis of the wooden toy coincides with the axis of the output shaft of the servo motor 8.

[0044] At this time, the staff activates the electric telescopic rod 52, causing the output shaft of the electric telescopic rod 52 to move downward, thereby driving the clamping plate 53 to move downward, thus fixing the wooden toy between the clamping plate 53 and the rotating plate 51.

[0045] When fixing the wooden toy, the electric telescopic rod 52 pushes downward, which not only clamps the wooden toy but also pushes the rotating plate 51 to move downward, thus causing the support block 72 to move downward. After the support block 72 moves downward, the area inside the air pressure pipe 71 increases, thus increasing the pressure inside the air pressure pipe 71. Therefore, the moving block 74 moves downward under the action of air pressure.

[0046] After the moving block 74 moves downward, it drives the rotating plate 75 to move downward, which in turn drives the height control plate 44 to move downward. This causes the height control plate 44 to drive the positioning rod 43 to move downward. Therefore, the positioning rod 43 can retract into the inside of the workbench 3 between processing of wooden toys, without affecting the processing of wooden toys.

[0047] At the same time, as the rotating plate 75 moves downward, it also drives the control block 76 to move downward.

[0048] As the control block 76 moves downward, the position of the control ball 711 remains unchanged, so the control ball 711 moves upward relative to the control block 76.

[0049] When the control ball 711 moves along the moving groove 79 into the reset groove 77, the control ball 711 pushes the spiral surface of the reset groove 77, thus driving the control block 76 to rotate and reset. This causes the control block 76 to drive the rotating plate 75 to rotate, thereby moving the height control plate 44 and the positioning rod 43 to the outermost position. Therefore, when the wooden toy is finished, it can be positioned directly for the next wooden toy without manual reset.

[0050] During processing, the operator adjusts the position of the grooving cutter 64 using a linear motor 61, and then controls the distance between it and the wooden toy using an electric push rod 62. After the adjustment is completed, the operator starts the servo motor 8, which drives the clamping plate 53 to rotate. The friction between the clamping plate 53 and the wooden toy, and the friction between the wooden toy and the rotating plate 51, causes the wooden toy to rotate, so that the grooving cutter 64 can groove on the outside of the cylindrical wooden toy.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
