Technical Field
[0001] This utility model relates to the field of clothes hanger board processing technology, specifically a clothes hanger board drilling mechanism. Background Technology
[0002] Clothes hanger boards are common household items, and mounting holes are usually drilled in them. Current technology often uses manual drilling machines or single-axis automated equipment for this process. However, traditional methods have the following drawbacks for clothes hanger boards requiring symmetrical or blind holes: firstly, they require two clamping operations or the use of two sets of equipment, resulting in low efficiency and difficulty in guaranteeing symmetry accuracy; secondly, blind hole depth control relies on manual experience, leading to poor consistency; and thirdly, the lack of an effective positioning and clamping mechanism makes the workpiece prone to displacement during processing, affecting hole position accuracy.

Detailed Implementation
[0015] To more specifically illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0016] like Figure 1-3 As shown, the clothes hanger board drilling mechanism includes a frame 1, a positioning unit 18, a drilling unit 8, and a fixing unit.
[0017] The positioning unit 18 includes two arc-shaped positioning blocks symmetrically arranged on the table surface of the frame 1. The concave arc surfaces of the two arc-shaped positioning blocks are arranged opposite each other. When the hanger board is lifted upward by the support block 7 driven by the lifting cylinder 6, the two arc-shaped positioning blocks and the support block 7 form a positioning channel for accommodating the hanger board. The arc-shaped edges on both sides of the hanger board contact the concave arc surfaces of the arc-shaped positioning blocks and are forcibly guided to the center position under the action of the vertical lifting force and the horizontal component force, thus achieving automatic centering.
[0018] The drilling unit 8 includes a lifting mechanism and a dual-sided synchronous drilling mechanism. The lifting mechanism includes a slide rail 2 vertically mounted on the frame 1, a slider 22 that slides with the slide rail 2, a lifting cylinder 3, and a floating joint 31 connected to the end of the piston rod of the lifting cylinder 3. The dual-sided synchronous drilling mechanism is connected to the slider 22 via a connecting plate 21, and the connecting plate 21 is driven by the piston rod of the lifting cylinder 3 via the floating joint 31. When the lifting cylinder 3 is activated, its piston rod drives the connecting plate 21 through the floating joint 31, thereby causing the drilling unit 8, which is fixed to the connecting plate 21, to move vertically along the slide rail 2.
[0019] The fixing unit includes a lifting cylinder 6, a support block 7, and a clamping unit 9. The support block 7 is mounted on the top of the piston rod of the lifting cylinder 6. The clamping unit 9 includes a clamping cylinder 10, a clamping block 11, and a clamping support 101. The clamping cylinder 10 is fixed to the clamping support 101, and the clamping support 101 is fixed to the frame 1. The clamping block 11 is connected to the end of the piston rod of the clamping cylinder 10. After the lifting cylinder 6 lifts the hanger panel and completes the centering, the clamping cylinder 10 drives the clamping block 11 to press down, firmly clamping the hanger panel onto the support block 7.
[0020] Automatic centering is achieved during the lifting process through symmetrical arc-shaped positioning blocks, stable suspension clamping is achieved through the coordinated action of the lifting and clamping mechanisms, and one-time symmetrical processing is achieved through the double-sided synchronous drilling mechanism. The entire set of mechanisms works closely together to achieve high-precision, high-efficiency, and automated production of clothes hanger board drilling.
[0021] In the above embodiment, two spindle motors 4 are symmetrically mounted on the front side of the connecting plate 21 via motor mounts. A drill bit 5 is mounted on the output shaft of each spindle motor 4 via a drill chuck. The two spindle motors 4 are controlled by the control system to start and stop simultaneously, driving their respective drill bits 5 to rotate synchronously. When the lifting cylinder 3 drives the drilling unit downwards, the two drill bits 5 simultaneously contact the workpiece and complete the drilling.
[0022] In the above embodiment, a negative pressure dust collection hood 121 is fitted around each drill bit 5. The negative pressure dust collection hood 121 is fixed to the connecting plate 21 by a bracket and moves together with the drilling unit. The negative pressure dust collection hood 121 is connected to the negative pressure dust collection pipe 12 fixed on the frame 1 through a flexible pipe. When drilling begins, the external central dust collection system or industrial vacuum cleaner is activated, forming a negative pressure at the suction port of the negative pressure dust collection hood 121 to promptly remove the debris generated during drilling.
[0023] In the above embodiment, the top of the support block 7 is machined into a smooth horizontal plane, and is strictly adjusted during installation to ensure that the plane is perpendicular to the axis of the drill bit 5. When the drill bit 5 descends to drill a hole, its tip will eventually reach the top surface of the support block 7, at which point the feed stops, and the top surface serves as a mechanical limit for the depth of the blind hole.
[0024] In the above embodiment, the clamping block 11 is machined into a smooth plane by a pressing machine. When the clamping cylinder 10 drives the clamping block 11 to press down, this plane achieves full contact with the upper surface of the clothes hanger board over a large area.
[0025] In the above embodiment, the slide rail 2 adopts a linear slide rail pair, the middle guide rail is vertically mounted on the frame 1 by bolts, and the slider 22 forms a sliding fit with the guide rail, which ensures the guidance of the drilling mechanism in the vertical direction.
[0026] The working principle of this utility model is as follows: The clothes hanger board is automatically delivered to this mechanism by the conveyor or robot arm of the previous process and accurately placed on the table of frame 1.
[0027] The positioning unit 18 includes two arc-shaped positioning blocks symmetrically arranged on the table surface of the frame 1. The concave arc surfaces of the two arc-shaped positioning blocks are arranged opposite each other. When the hanger board is lifted upward by the support block 7 driven by the lifting cylinder 6, the two arc-shaped positioning blocks and the support block 7 form a positioning channel for accommodating the hanger board. The arc-shaped edges on both sides of the hanger board contact the concave arc surfaces of the arc-shaped positioning blocks and are forcibly guided to the center position under the action of the vertical lifting force and the horizontal component force, thus achieving automatic centering.
[0028] When the hanger board is lifted to the predetermined drilling height, the piston rod of the clamping cylinder 10 extends downward, driving the clamping block 11 to move downward, firmly pressing the hanger board onto the support block 7 from above, forming a stable suspended clamping state.
[0029] The piston rod of the lifting cylinder 3 extends downward and pushes the connecting plate 21 through the floating joint 31, thereby driving the entire drilling unit 8 to descend smoothly along the slide rail 2. At the same time, the two spindle motors 4 start, driving the left and right drill bits 5 to rotate at high speed, completing the synchronous drilling operation on both sides of the clothes hanger board.
[0030] The drill bit 5 stops feeding when its tip contacts the top surface of the support block 7, and the depth of the blind hole is controlled by this mechanical limiting method.
[0031] After drilling is completed, the lifting cylinder 3 drives the drilling unit 8 to rise and reset, the spindle motor 4 stops rotating, and then the clamping cylinder 10 and the lifting cylinder 6 reset in sequence, and the support block 7 descends to the initial position.
[0032] Throughout the drilling process, the negative pressure dust collection system continuously sucks up the debris generated during drilling through the negative pressure dust collection hood 121.
[0033] The finished hanger panels are automatically conveyed to the next assembly process by a subsequent conveying device.
[0034] The drilled hanger board is conveyed to the board flipping mechanism 16 via a conveyor device for flipping, while the hanger crossbar is conveyed to the assembly station via the crossbar conveyor mechanism 15. The flipped hanger board and hanger crossbar meet at the hook assembly mechanism 17, and the hooks are inserted into the drilled holes in the hanger board by an automatic pressing device to complete the hanger assembly. The final finished product is automatically sorted and output by the finished product unloading mechanism 14.
[0035] The entire process is automated through a PLC control system, with precise coordination of the sequence and timing of actions of each actuator to ensure the stability and reliability of the processing. Through the collaborative operation of each unit, a complete hanger production line is formed, achieving high-precision, high-efficiency automated processing of hangers.
[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
