Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for drilling holes in the center of toy discs. Background Technology

[0002] A drilling device is a general term for equipment used to process holes in solid materials. It mainly uses a drill bit to leave cylindrical holes in the workpiece through rotary cutting or rotary extrusion. Drilling devices are also commonly used in the production of wooden toys. The drilling device drills holes in the center of the wooden toy discs. Traditional drilling devices have fixed molds, with a mold located directly below the drill bit. When a wooden toy disc needs drilling, it is simply placed on the mold. However, this type of drilling device has certain limitations. Due to the mold, the drilling device can only drill holes in wooden toy discs of a single size. Drilling multiple wooden toy discs of different sizes becomes relatively cumbersome.

[0003] To address the aforementioned issues, as described in patent CN213197951U, a device for drilling holes in the center of wooden toy discs is used. The wooden toy disc to be drilled is placed between the first sliding end 7 and the second sliding end 8. The distance between the first sliding end 7 and the second sliding end 8 is adjusted according to the radius of the wooden toy disc; that is, the distance between the first sliding end 7 and the second sliding end 8 is the diameter of the wooden toy disc. After the distance is adjusted, the first telescopic drive device 3 and the second telescopic drive device 4 are activated, raising the height of the supporting device 5. When the height of the supporting device 5 reaches a suitable position with the drill bit 18, the first telescopic drive device 3 and the second telescopic drive device 4 are closed, and the motor 15 is started. The rotation of the motor shaft 16 drives the rotation of the coupling 17, which in turn drives the rotation of the drill bit 18, thus achieving the drilling of the wooden toy disc.

[0004] The above-mentioned device and technical solution still have some shortcomings in practical application. Although the relatively sliding first and second sliding ends can be used to side-fit and position the toy disc, there are no stable limiting measures for the first and second sliding ends. This makes it easy for the toy disc and the sliding ends to loosen and slip during the drilling process, resulting in drilling failure. In addition, the relatively sliding first and second sliding ends lack centering and limiting measures for the toy disc. During the clamping process, the toy disc is prone to tilting relative to the drill bit in the front-back and left-right directions, thereby reducing the drilling quality of the toy. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] Therefore, the purpose of this utility model is to provide a drilling device for the center of toy discs, in order to solve the problems mentioned in the background art. The existing drilling devices for the center of toy discs can only drill holes in wooden toy discs of one specification, and there are no stable limiting measures for the first sliding end and the second sliding end. As a result, the toy disc and its sliding end are prone to loosening and slipping during the drilling process. In addition, during the clamping process, the toy disc is prone to tilting relative to the drill bit in the front-back and left-right directions, thereby reducing the drilling quality of the toy.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for the center of a toy disc, comprising a base, an mounting box fixed on the upper part of the base, V-shaped clamps facing each other on both sides of the mounting box, and sliding components cooperating with the V-shaped clamps, the two V-shaped clamps forming a horizontally opposite or back-to-back sliding engagement through the sliding components, and an electric push rod for driving the two V-shaped clamps to move synchronously opposite or back-to-back, a supporting truncated cone fixed inside the mounting box is provided in the middle part of the two V-shaped clamps, and a drill bit vertically aligned with the supporting truncated cone, and a lifting rotary drive assembly for driving the drill bit to move up and down and rotate horizontally.

[0008] As a preferred embodiment of the toy disc center drilling device described in this utility model, the sliding component includes fixed ears fixed on both sides of the V-shaped clamp, a sliding sleeve fixed on the outer end of the fixed ears, and a guide rod that slides horizontally and matches the inner side of the sliding sleeve and is fixed at both ends to the inner side of the mounting box.

[0009] The electric actuator cylinder body is fixed to the side wall of the mounting box, and the piston rod end of the electric actuator is fixedly connected to one side of the V-shaped clamp.

[0010] As a preferred embodiment of the drilling device for the center of a toy disc described in this utility model, the inner side of the V-shaped groove of the V-shaped clamp has a rubber pad that matches its contour.

[0011] As a preferred embodiment of the drilling device for the center of a toy disc described in this utility model, the supporting truncated cone has a vertical clearance hole at its center, and one side of the supporting truncated cone also has a connecting arm fixed to the side wall of the vertical section of the mounting box.

[0012] As a preferred embodiment of the drilling device for the center of a toy disc described in this utility model, the rotary drive assembly includes a hydraulic rod vertically fixed to the upper end of the mounting box and a drilling motor fixed to the bottom piston rod end of the hydraulic rod, wherein the drill bit is fixed to the bottom output shaft end of the drilling motor.

[0013] As a preferred embodiment of the drilling device for the center of a toy disc described in this utility model, the air-blowing cleaning component includes:

[0014] The device includes an L-shaped air supply pipe fixed to one side inside the mounting box, a high-pressure jet nozzle located at the outer end of the lower horizontal section of the L-shaped air supply pipe, and a connecting nozzle located at the top of the mounting box and connected to the upper end of the L-shaped air supply pipe. As a preferred embodiment of the toy disc center drilling device described in this invention, a dust collection box is removable and fitted to the lower inner side of the mounting box, and a protective door is also provided on the front of the mounting box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This device for drilling holes in the center of toy discs involves placing the wooden toy disc roughly in the center on a supporting circular platform. Then, with the cooperation of the sliding component and the electric push rod, the V-shaped clamps on both sides move closer together. Under the action of the relatively clamped V-shaped grooves, the toy disc is automatically corrected and centered and stabilized, so that the center point of the toy disc is on the same vertical line as the drill bit axis. Furthermore, with the cooperation of the sliding component and the electric push rod, the V-shaped clamps can be firmly fixed, effectively avoiding the loosening and slippage of the toy disc during drilling, and the tendency of the toy disc to deviate from the drill bit in the front-back and left-right directions. This ensures the quality and operational efficiency of drilling holes in the center of the toy disc. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Figures 1-4 The diagram shown is a complete structural schematic of a drilling device for the center of a toy disc according to this utility model. Please refer to [link / reference]. Figures 1-4 This embodiment of a device for drilling holes in the center of a toy disc includes a base 100, a mounting box 110 fixed on the upper part of the base 100, and two opposing V-shaped clamps 200 and sliding components 300 that cooperate with the V-shaped clamps 200 on both sides of the middle layer of the mounting box 110. The two V-shaped clamps 200 are horizontally opposite or back-to-back slidingly engaged through the sliding components 300. The device also includes an electric push rod 400 for driving the two V-shaped clamps 200 to move synchronously opposite or back-to-back. A support frustum 500 fixed inside the mounting box 110 is also provided in the middle part of the two V-shaped clamps 200. The upper part of the inner side of the mounting box 110 has a drill bit 600 vertically aligned with the support frustum 500 and a lifting rotary drive assembly 700 for driving the drill bit 600 to move up and down and rotate horizontally.

[0025] The sliding assembly 300 includes fixing ears 310 fixed to both sides of the V-shaped clamp 200, a sliding sleeve 320 fixed to the outer end of the fixing ears 310, and a guide rod 330 that slides horizontally and matches the inner side of the sliding sleeve 320 and is fixed at both ends to the inner side of the mounting box 110. The cylinder portion of the electric push rod 400 is fixed to the side wall of the mounting box 110, and the piston rod end of the electric push rod 400 is fixedly connected to one side of the V-shaped clamp 200. It can be understood that, compared to the flat clamping surfaces of the first and second sliding ends in the prior art, by using the V-shaped clamp 200, the V-shaped grooves on both sides can be used to automatically correct and center the toy disc. The inner side of the V-shaped clamping groove of the V-shaped clamp 200 has a rubber pad 210 that matches its contour. The rubber pad 210 prevents the V-shaped clamps 200 on both sides from causing damage to the wooden toy disc, while also providing a more stable clamping. A clearance hole 5001 is vertically provided at the center of the supporting frustum 500, and a connecting arm 510 fixed to the vertical side wall of the mounting box 110 is also provided on one side of the supporting frustum 500. The clearance hole 5001 allows the drill bit 600 to pass through easily, while the horizontally provided connecting arm 510 allows the chip collection box 900 below to be freely pulled out and placed. It should be noted that the diameter of the supporting frustum 500 should be smaller than the diameter of the toy disc so that the V-shaped clamps 200 on both sides can clamp more reasonably. In other embodiments, the supporting frustum 500 can also be made into a replaceable form, which is not limited. The rotary drive assembly 700 includes a hydraulic rod 710 vertically fixed to the upper end of the mounting box 110 and a drilling motor 720 fixed to the bottom piston rod end of the hydraulic rod 710. The drill bit 600 is fixed to the bottom output shaft end of the drilling motor 720. Specifically, in this embodiment, during use, the wooden toy piece is roughly centered on the supporting frustum 500. Then, with the cooperation of the sliding component 300 and the electric actuator 400, the V-shaped clamps 200 on both sides move closer together. Under the action of the relatively clamped V-shaped grooves, the toy piece is automatically corrected and centered and stabilized, so that the center point of the toy piece is on the same vertical line as the axis of the drill bit 600. With the cooperation of the sliding component 300 and the electric actuator 400, the V-shaped clamps 200 can be firmly fixed, effectively avoiding the loosening and slippage of the toy piece during drilling, and the tendency of the toy piece to deviate from the drill bit in the front-back and left-right directions, which is common in the prior art. This ensures the quality of drilling the center of the toy piece and the efficiency of operation.

[0026] Furthermore, as a preferred embodiment, the air-blowing cleaning assembly 800 includes an L-shaped air supply pipe 810 fixed inside one side of the mounting box 110, a high-pressure jet nozzle 820 located at the outer end of the lower horizontal section of the L-shaped air supply pipe 810, and a connecting nozzle 830 located at the top of the mounting box 110 and connected to the upper end of the L-shaped air supply pipe 810. Since some sawdust inevitably adheres to the drill bit 600 after drilling, excessive sawdust can affect drilling accuracy. Therefore, after each drilling operation and after the drill bit 600 is raised, the L-shaped air supply pipe 810 can use the high-pressure jet nozzle 820 to blow high-pressure air onto the outer wall of the drill bit 600, and the drilling motor 720 will drive the drill bit 600 to rotate continuously, effectively blowing away and peeling off the adhered sawdust. It should be noted that the connecting nozzle 830 is connected to the air pump via an external pipeline; during use, simply turn on the air pump. The configuration is simple and easy to maintain.

[0027] Furthermore, as a preferred embodiment, a shavings collection box 900 can be pulled out and fitted to the lower inner side of the mounting box 110, and a protective door 120 is also provided on the front of the mounting box 110. It is understood that sawdust falling during drilling and sawdust falling during air blowing will automatically fall into the shavings collection box 900, while a small amount of sawdust falling on, for example, the V-shaped clamp 200 will not affect the clamping operation of the clamp, so it does not need to be concerned. The protective door 120 can prevent sawdust from splashing out during drilling and air blowing. When cleaning or loading and unloading materials, the protective door 120 can be opened or closed at will, making the operation simple.

[0028] In summary, the device for drilling the center of a toy disc according to this embodiment first places the wooden toy disc roughly centered on the supporting frustum 500. Then, with the cooperation of the sliding component 300 and the electric push rod 400, the V-shaped clamps 200 on both sides move closer together. Under the action of the V-shaped grooves that clamp each other, the toy disc is automatically corrected and centered and stabilized, so that the center point of the toy disc is on the same vertical line as the axis of the drill bit 600. With the cooperation of the sliding component 300 and the electric push rod 400, the V-shaped clamps 200 can be firmly fixed, effectively avoiding the loosening and slippage of the toy disc during drilling, and the easy deviation of the toy disc relative to the drill bit in the front-back and left-right directions. Then, the protective door 120 is closed, and the hydraulic rod 710 drives the drilling motor 720 to descend. At the same time, the drilling motor 720 drives the drill bit 600 to rotate rapidly and drill the axial hole of the toy disc below. After completion, it can be lifted and returned.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
