Description

Technical Field

[0001] This utility model relates to the field of bead drilling technology, and in particular to a bead drilling machine. Background Technology

[0002] The process of making collectible beads involves turning the raw material into a cylinder or cube, then performing a fine drilling process, and finally, through rough and fine grinding, the bead gradually takes on a perfect round shape and becomes a bead.

[0003] The existing bead drilling equipment operates by manually placing the raw bead material on the positioning clamp at the bottom of the drill, manually moving the drill down to drill a hole, and then manually moving the drill up again. Although the drill is equipped with hydraulic assistance, such frequent manual operation over a long period of time will increase the physical burden on the operator and is not conducive to efficient production and processing.

[0004] To address the aforementioned problems, a bead punching machine was proposed. Utility Model Content

[0005] The main purpose of this invention is to provide a bead punching machine that solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A bead punching machine includes a frame, on which a punching and feeding mechanism is mounted;

[0008] The punching and feeding mechanism includes a feeding top cylinder that is slidably installed with the top plate of the frame. A hollow bearing column is fixed in the cavity of the feeding top cylinder. A second shaft pin is movably inserted into the bottom end of the feeding top cylinder. A second drive arm is hinged on the second shaft pin.

[0009] The punching and feeding mechanism also includes a first hinge seat fixed to the frame support leg, a first drive arm hinged in the first hinge seat, and a foot control rod inserted and fixed in the lower end of the first drive arm.

[0010] Furthermore, a mounting column is screwed to one side of the top of the frame, and a clamping arm is detachably mounted on the mounting column. A punching motor is clamped inside the clamping arm, and a hole opener is keyed to the power shaft of the punching motor. The hole opener is vertically aligned with the hollow support column.

[0011] Furthermore, the inner cavity of the hollow support column is a hemispherical structure with an opening at the bottom.

[0012] Furthermore, a second hinge seat is fixedly installed at the top of the frame, and a motor controller is fixedly encapsulated inside the second hinge seat. The motor controller consists of a rotating outer shell and a fixed core. One end of the fixed core is fixed to the inner wall of the second hinge seat, and the outer end of the rotating outer shell extends out of the second hinge seat and is fixedly connected to the inner side wall of the second drive arm. The other contact surface between the second drive arm and the second hinge seat is rotatably mounted via a shaft.

[0013] Furthermore, a connecting rod is hinged in the U-shaped groove of the second drive arm, and a first shaft pin is inserted into the bottom of the connecting rod.

[0014] Furthermore, the first pivot pin is hinged to a through hole on the first drive arm.

[0015] Furthermore, a control box is fixed to the back of the frame.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This invention designs a punching and feeding mechanism. By controlling the foot pedal control lever and the first drive arm, the connecting rod moves downward, pulling one end of the second drive arm downward, while the other end rises and pushes out the feeding top cylinder. This actively and vertically moves the beads placed in the hollow support column to contact the punching device for punching. The punching motor starts synchronously when the second drive arm rotates through the motor controller. This operation can greatly improve the punching efficiency of beads and save manpower.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-4 As shown, this embodiment provides a bead punching machine, including a frame 1, on which a punching and feeding mechanism 4 is mounted. The punching and feeding mechanism 4 includes a feeding top cylinder 407 slidably mounted with the top plate of the frame 1. A hollow bearing column 408 is fixed in the cavity of the feeding top cylinder 407. A second shaft pin 407a is movably inserted into the bottom end of the feeding top cylinder 407. A second drive arm 405 is hinged to the second shaft pin 407a. The punching and feeding mechanism 4 also includes a first hinge seat 401 fixed to the support leg of the frame 1. A first drive arm 402 is hinged inside the first hinge seat 401. A foot control rod 403 is inserted and fixed inside one lower end of the first drive arm 402.

[0026] In the above structure, the hollow support column 408 is used to hold the raw material of beads for drilling. The raw material is usually a cylindrical or cubic structure of wood. The pre-processed size of the raw material is close to the inner wall of the hollow support column 408, which is convenient for clamping and fixing, and prevents displacement during drilling. The top of the feeding top cylinder 407 is clamped to the top of the machine base by a disc, so that it can maintain a stable initial height and facilitate loading.

[0027] A mounting column 2 is fixed to the top side of the frame 1 with screws. A clamping arm 3 is detachably installed on the mounting column 2. A punching motor 5 is clamped in the clamping arm 3. A hole opener 6 is keyed to the power shaft of the punching motor 5. The hole opener 6 is vertically aligned with the hollow support column 408. The mounting column 2 is provided with several through holes and mounting rails, which can easily adjust the fixed position of the punching motor 5.

[0028] The inner cavity of the hollow support column 408 is a hemispherical structure with an opening at the bottom, allowing the perforator 6 to enter the interior of the hollow support column 408 after penetrating the bead raw material.

[0029] A second hinge seat 406 is fixedly installed at the top inside the frame 1. A motor controller 406a is fixedly encapsulated inside the second hinge seat 406. The motor controller 406a consists of a rotating outer shell and a fixed core. One end of the fixed core is fixed to the inner wall of the second hinge seat 406. The outer end of the rotating outer shell extends out of the second hinge seat 406 and is fixedly connected to the inner side wall of the second drive arm 405. The other contact surface between the second drive arm 405 and the second hinge seat 406 is rotatably mounted via a shaft.

[0030] In the above structure, the second drive arm 405 can rotate through the rotating housing of the motor controller 406a and the second hinge seat 406. When rotating, it acts on the fixed core of the motor controller 406a, thereby synchronously starting the drilling motor 5. The principle of the motor controller 406a is the same as that of a common speed control handle. The speed control handle is mainly composed of four parts: a linear Hall element, a return spring, a magnet assembly, and a rotating handle. When the handle is rotated, the position and direction of the magnet assembly fixed inside the handle change, and the direction of the magnetic field sensed by the linear Hall changes from weak to strong. The Hall output terminal will output a changing voltage of 1-4.2V. Since this voltage is low, it cannot directly drive the motor. This voltage is provided to the operational amplifier of the controller for comparison with the set value. Based on the comparison result, a voltage value is output to drive the field-effect transistor. The field-effect transistor is connected to the power supply. When the field-effect transistor is turned on, the output voltage drives the electric vehicle motor to rotate.

[0031] A connecting rod 404 is hinged in the U-shaped groove of the second drive arm 405. A first shaft pin 402a is inserted into the bottom of the connecting rod 404. When the second drive arm 405 bends downward, the reset spring of the motor controller 406a is compressed. After the external force is released, the reset spring resets, and the motor controller 406a is reset to the initial position. At the same time, the second drive arm 405 is reset, which in turn restores the linked feeding top cylinder 407 to the initial position.

[0032] The first pivot pin 402a is hinged in the through hole on the first drive arm 402.

[0033] The back of the rack 1 is fixed with a control box 7, which contains a signal processor, controller and power distribution components.

[0034] The working principle of this device is as follows: This device is connected to an external power source when in use.

[0035] During drilling, the raw material of the bead to be drilled is manually placed inside the hollow support column 408. The foot presses down on the control lever 403, causing the first drive arm 402 to bend downwards along the first hinge seat 401. This, in turn, causes the connecting rod 404 to move downwards via the first shaft pin 402a. The top of the connecting rod 404, through a hinge structure, causes this end of the second drive arm 405 to move downwards. When the second drive arm 405 rotates, it acts on the motor controller 406a, which sends a control signal into the control box 7. After processing by the controller, the drilling motor 5 is started synchronously to drive the hole opener 6 to rotate at high speed. The other end of the second drive arm 405 rises and drives the feeding top cylinder 407 to move up and out along the top plate wall of the base through the second shaft pin 407a. The hollow support column 408 located at the top is moved vertically upward and close to the high-speed rotating hole opener 6, and is continuously and slowly fed until the hole opener 6 penetrates the raw material. The drilling ends, the foot control rod 403 is released, the second drive arm 405 is reset, and the feeding top cylinder 407 exits the hole opener 6.

[0036] By adopting the above structure, the physical effort required for drilling can be reduced, thereby greatly improving the efficiency of drilling.

[0037] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0038] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
