Description

Technical Field

[0001] This invention relates to the field of polishing, and more particularly to an intelligent hardware polishing machine. Background Technology

[0002] In existing hardware polishing technologies, for workpieces with complex shapes and high precision requirements, manual polishing is still typically performed by holding the hardware directly in contact with a high-speed rotating polishing wheel. Operators rely on experience and feel to continuously adjust the pressing angle, contact force, and movement trajectory of the hardware to achieve uniform polishing of different curved surfaces and concave corners. This purely manual method has certain advantages in flexibility, adapting to local irregularities in the workpiece. However, prolonged and continuous polishing of multiple hardware components can easily lead to hand fatigue, soreness, and even... Spasms can lead to uncontrollable hand tremors, resulting in over-grinding, burn marks, or uneven textures on the polished surface, severely affecting the consistency of product quality. There is also a risk of injury from accidental contact with the polishing wheel due to hand tremors. Although industrial robots can be used to hold and polish hardware, their equipment investment is high and programming is complex. For delicate operations that require real-time adaptive adjustment of pressure, tilt angle, and reciprocating movement along the workpiece axis, the rigid gripping and fixed trajectory of the robot often cannot achieve the smooth control and multi-degree-of-freedom response of a human hand, and the polishing effect is actually inferior to that of a skilled worker.

[0003] In summary, how to effectively reduce the burden of manual operation and minimize adverse factors such as hand tremors while ensuring the flexibility and precision of polishing has become an urgent technical problem to be solved in the current polishing process. Summary of the Invention

[0004] To overcome the drawbacks of traditional manual polishing of hardware parts, where workers' hands are prone to fatigue and tremors, affecting product quality and posing safety threats, this invention provides an intelligent hardware polishing machine.

[0005] The technical implementation scheme of the present invention: An intelligent hardware processing and polishing machine includes a main mounting frame, a secondary mounting frame, a spline shaft, a drive motor, a central polishing wheel, side polishing wheels, a push-pull ring, a limit slide rod, an electric push rod, an isolation cover, an electric lifting platform, a column, a vertical slider, a pressure sensor, a compression spring, and a support assembly; the spline shaft is rotatably connected to the main mounting frame; a drive motor for driving the spline shaft to rotate is mounted on the main mounting frame; a central polishing wheel is fixedly connected to the center of the spline shaft; two side polishing wheels are slidably connected to the spline shaft; a push-pull ring is rotatably connected to each of the two side polishing wheels on opposite sides; a limit slide rod is fixedly connected to the push-pull ring; the limit slide rod is slidably connected to the main mounting frame; a left... Two electric push rods on the right are used to move the push-pull rings on the same side; two isolation covers on the left and right are fixed to the main mounting frame to protect the outer side of the side polishing wheel on the same side; two auxiliary mounting frames on the left and right are fixed to the main mounting frame; two electric lifters are mounted on the auxiliary mounting frames; columns are fixed to the lifting components of the electric lifters; vertical sliders are slidably connected to the columns; pressure sensors are installed on the lifting components of the electric lifters; compression springs are fixed between the vertical sliders and the sensing components of the corresponding pressure sensors; support components for supporting hardware are connected between the two corresponding vertical sliders at the front and rear; the two support components are located on the left and right sides above the central polishing wheel, respectively; and an intelligent timer is built into the electric lifter.

[0006] Furthermore, the central polishing wheel has several central heat dissipation holes; the side polishing wheel has several side heat dissipation holes corresponding to the central heat dissipation holes.

[0007] Furthermore, the radial width of the isolation cover is greater than the radial width of the side polishing wheel.

[0008] Furthermore, an alarm is installed on the pillar.

[0009] Based on the above scheme, a rubber pad is further fixed to the side of the side polishing wheel facing the central polishing wheel; the rubber pad has a number of transfer heat dissipation hole structures that connect to the corresponding side heat dissipation holes.

[0010] Furthermore, the isolation enclosure is equipped with intelligent identification sensors to detect whether foreign objects have intruded.

[0011] Based on the above scheme, the support component further consists of a transition block, a fixing rod, and a support plate; each of the two corresponding vertical sliders at the front and rear is connected to a transition block; a fixing rod is fixedly connected to the transition block; and a support plate is fixedly connected between the two corresponding fixing rods at the front and rear.

[0012] Furthermore, the support plate is made of rubber sheet material.

[0013] Furthermore, the adapter block is rotatably connected to the corresponding vertical slider; a torsion spring is fixed between the adapter block and the corresponding vertical slider.

[0014] Furthermore, the vertical slider is fixed with a limiting rod to limit the downward stretching stroke of the corresponding support piece.

[0015] The beneficial effects of this invention: This invention describes an intelligent hardware polishing machine. An electric lift with a vertical slider provides a support component. The machine polishes hardware in multiple stages. In each stage, the electric lift moves the hardware on the support component downwards towards the central polishing wheel. The operator only needs to press down and adjust the angle to place the hardware against the central polishing wheel for polishing, eliminating the need to hold the hardware suspended in the air throughout the process, significantly reducing hand fatigue. After the current stage's timing is completed, the electric lift's built-in intelligent timer forcibly pushes the support component, moving the hardware upwards... The polishing wheel moves away from the central polishing wheel, ending the current polishing stage. This forces the hand to rest intermittently and ensures sufficient heat dissipation time for the workpiece and polishing wheel, improving operational safety. In addition, two side polishing wheels are provided. The side polishing wheels are initially stored in the isolation cover to prevent accidental hand contact. After the side polishing wheels are placed against one side of the central polishing wheel, the operation flexibility of polishing hardware parts can be enhanced. This solves the technical problem that in traditional manual polishing of hardware parts, the worker's hands are prone to fatigue and tremors, which affects the product quality of polishing work and poses a safety threat to the human body.

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0025] Example 1: An intelligent hardware processing and polishing machine according to this example, such as... Figures 1-5As shown, it includes a main mounting bracket 11, a secondary mounting bracket 12, a splined shaft 21, a drive motor 22, a center polishing wheel 23, a side polishing wheel 24, a push-pull ring 25, a limit slide bar 251, an electric push rod 26, an isolation cover 28, an electric lift 31, a column 32, a vertical slider 33, a pressure sensor 34, a compression spring 35, an alarm 36, and a support assembly 4; the splined shaft 21 is rotatably connected to the main mounting bracket 11; the drive motor 22 is mounted on the main mounting bracket 11; the output shaft of the drive motor 22 is fixedly connected to the splined shaft 21; A central polishing wheel 23 is fixedly connected to the middle of the spline shaft 21; a side polishing wheel 24 is slidably connected to the left and right sides of the spline shaft 21, and the initial distance between the side polishing wheel 24 and the central polishing wheel 23 is greater than the radial width distance of the hardware to be processed in the left-right direction; a push-pull ring 25 is rotatably connected to the opposite sides of the two side polishing wheels 24; two front and rear limit slide rods 251 are fixedly connected to the two push-pull rings 25; all limit slide rods 251 are slidably connected to the main mounting bracket 11; the left and right sides of the main mounting bracket 11 are each equipped with a push-pull ring 24. The main mounting frame 11 is equipped with an electric push rod 26; the telescopic ends of the two electric push rods 26 are respectively fixed to push-pull rings 25 on the same side; an isolation cover 28 is fixed to the left and right sides of the main mounting frame 11, and the two side polishing wheels 24 are initially isolated and protected within the isolation cover 28 on the same side; a secondary mounting frame 12 is fixed to the left and right sides of the main mounting frame 11; an electric lift 31 is installed on the front and rear sides of the two secondary mounting frames 12; a column 32 is fixed to the lifting component of each electric lift 31; each column 32... Each of the two vertical sliders 33 is connected to a vertical slider 33; each of the lifting components of each electric lift 31 is equipped with a pressure sensor 34; each vertical slider 33 is fixedly connected to the sensing component of the corresponding pressure sensor 34 with a compression spring 35; each pair of vertical sliders 33 that are opposite each other is connected to a support component 4; the two support components 4 are initially located on the left and right sides above the central polishing wheel 23; each electric lift 31 has a built-in intelligent timer; each column 32 has an alarm 36 installed at its top.

[0026] like Figures 1-3As shown, the central polishing wheel 23 has several central heat dissipation holes 2301; the two side polishing wheels 24 each have several side heat dissipation holes 2401 corresponding to the central heat dissipation holes 2301; the radial width of the two isolation shells 28 in the left and right directions is greater than the radial width of the side polishing wheels 24 in the left and right directions, ensuring that the side polishing wheels 24 can be stored deep inside the isolation shells 28 in the initial stage. When the worker holds the hardware and adjusts the angle on the support component 4 to carry out polishing work, even if the worker's hand or the hardware he is holding accidentally touches the isolation shell 28, the worker's hand or the hardware he is holding will be blocked by the isolation shell 28 and will not be able to continue to enter the isolation shell 28, ensuring that the worker's hand or the hardware he is holding will not come into contact with the side polishing wheels 24 that are rotating at high speed inside the isolation shell 28.

[0027] The polishing steps of an intelligent hardware processing and polishing machine are as follows.

[0028] First, the staff places the hardware between the two support components 4. Under its own weight, the hardware applies downward pressure to the compression spring 35 through the support components 4 and the vertical slider 33. The elastic deformation force generated by the downward compression spring 35 triggers the pressure sensor 34, allowing the pressure sensor 34 to recognize that there is a hardware on the support component 4 and prepare to start the polishing work. At this time, the drive motor 22 drives the spline shaft 21 to drive the central polishing wheel 23 and the side polishing wheels 24 initially located on both sides to rotate at high speed, and polish the hardware in multiple stages.

[0029] During each polishing stage, the electric lift 31 pulls the vertical slider 33 on the column 32, along with the support assembly 4 and the placed hardware, downwards towards the central polishing wheel 23. Supported by the two support plates 43, the hardware is suspended 2-5cm above the central polishing wheel 23. The built-in intelligent timer on the electric lift 31 begins timing. At this point, the worker simply needs to press down on the hardware to move the support assembly 4 and push the vertical slider 33 downwards. The vertical slider 33 then compresses the compression spring 35 further downwards, allowing the bottom of the hardware to smoothly contact the high-speed rotating central polishing wheel. The polishing wheel 23 performs polishing work, while the operator manually rotates the hardware around its own axis, allowing the hardware to be polished while rotating. This causes the hardware to move back and forth between the two supporting components 4 in the left and right direction. At the same time, the operator continuously adjusts the downward compression of the hardware, which causes the compression spring 35 to compress downward, according to the diameter of different areas of the hardware. This allows the central polishing wheel 23 to smoothly contact each area of ​​the hardware for polishing. During this process, when the operator's hand touches the isolation cover 28 while constantly adjusting the grip posture, the operator's hand is blocked by the isolation cover 28 and will not come into contact with the side polishing wheel 24.

[0030] After the intelligent timer built into the electric lift 31 finishes its current stage of polishing, the alarm 36 briefly sounds to remind the worker to stop the polishing work. The electric lift 31 then pushes the column 32 and the vertical slider 33 and their connected support assembly 4 upwards. The support assembly 4 forcibly pulls the hardware upwards away from the central polishing wheel 23, reminding the worker to stop the polishing work of the current stage. This allows the worker's hands to rest intermittently and the hardware and the central polishing wheel 23 to have sufficient time to dissipate heat before the next stage of polishing begins. This achieves automatic forced control of the polishing time of each stage. After the polishing work of a stage is completed, the hardware is forcibly disengaged from the high-speed rotating central polishing wheel 23. This forces the worker to rest intermittently and ensures that the workpiece and the polishing wheel have sufficient time to dissipate heat, greatly reducing the risk of overheating damage or safety accidents that are prone to occur in traditional manual polishing.

[0031] In addition, when polishing the continuous large arc structure on the surface of the hardware, before the polishing work begins at a certain stage, the operator controls the electric push rods 26 on both sides to push the push-pull rings 25 on the same side, which drive the side polishing wheels 24 to move towards the center polishing wheel 23. The push-pull rings 25 drive the limit slide rods 251 to move along the main mounting frame 11 until the center polishing wheel 23 and the two side polishing wheels 24 are combined to form a thickened polishing wheel structure. When starting the polishing work at this stage, the operator can use a smaller adjustment angle to allow the continuous large arc structure of the hardware to smoothly contact the center polishing wheel 23 and the side polishing wheels 24, thereby improving the efficiency of polishing the hardware. During the polishing work, the center polishing wheel 23 and the side polishing wheels 24 can dissipate heat through the central heat dissipation hole 2301 and the side heat dissipation hole 2401, respectively, to avoid heat accumulation on the center polishing wheel 23 and the side polishing wheels 24.

[0032] Example 2, based on Example 1, such as Figures 1-5 As shown, in this embodiment of an intelligent hardware processing and polishing machine, a rubber pad 27 is fixedly attached to each of the two side polishing wheels 24 facing the central polishing wheel 23. Each of the two rubber pads 27 has a plurality of transfer heat dissipation holes 2701 that connect to the corresponding side heat dissipation holes 2401. When the side polishing wheels 24 are pressed against the central polishing wheel 23, the transfer heat dissipation holes 2701 on the rubber pads 27 can connect the side heat dissipation holes 2401 on both sides with the central heat dissipation hole 2301, ensuring that the side heat dissipation holes 2401 and the central heat dissipation hole 2301 can be smoothly connected to the outside airflow for normal heat dissipation. An intelligent identification sensor 29 is installed on each of the two isolation covers 28.

[0033] During polishing operations, the worker holds the hardware component and adjusts it at different angles on the support assembly 4. When the side polishing wheel 24 is inside the isolation housing 28, even if the worker's hand or one end of the hardware component accidentally enters the isolation housing 28, the intelligent recognition sensor 29 in the isolation housing 28 will immediately detect the intrusion. At this time, the drive motor 22 will forcibly stop rotating the center polishing wheel 23 and the side polishing wheel 24 on the spline shaft 21, causing the rotation speed of the center polishing wheel 23 and the side polishing wheel 24 to decrease sharply, forcibly terminating the current stage of polishing work. This achieves the goal of preventing the high-speed rotation of the center polishing wheel 23 and the side polishing wheel 24 from being affected by the active emergency stop system. 4. Direct harm to the human body: In the event of an extreme operational error by the worker holding the hardware, even if the worker's hand or the hardware they are holding penetrates into the isolation cover 28 near the side polishing wheel 24, the penetrating worker's hand or the hardware they are holding will come into contact with the rubber pad 27 on the side polishing wheel 24, rather than directly contacting the side polishing wheel 24. Moreover, the rubber pad 27 is in the deceleration phase, which greatly reduces the harm to the penetrating worker's hand or the hardware they are holding, and improves the safety of the polishing work. It retains the advantages of high-efficiency polishing work in the above embodiments, and provides a reliable safety net for workers. It is especially suitable for long-term, highly repetitive manual polishing operations, and significantly reduces the risk of work-related injuries.

[0034] Example 3, based on Example 1, such as Figures 1-7 As shown, in this embodiment of an intelligent hardware processing and polishing machine, the support assembly 4 consists of a transition block 41, a fixing rod 42, a support plate 43, a torsion spring 44, and a limiting rod 45. A transition block 41 is rotatably connected to each of the two corresponding vertical sliders 33. A fixing rod 42 is fixedly connected to each of the two transition blocks 41. A support plate 43 is fixedly connected between the two corresponding fixing rods 42. The support plate 43 is designed as a curved arc structure with a downward bend in the middle. The support plate 43 is made of rubber sheet material with stretchable elastic deformation properties. A torsion spring 44 is fixedly connected between each of the two transition blocks 41 and the corresponding vertical slider 33. A limiting rod 45 is fixedly connected to the left and right sides of each of the two vertical sliders 33, and the limiting rod 45 is located below the corresponding support plate 43.

[0035] During the polishing process of the hardware, the worker places the hardware horizontally between the curved structures of the two support plates 43. At this time, the pressure sensor 34 is triggered, and the electric lift 31 drives the column 32 and the vertical slider 33 and the entire support assembly 4 connected to them to move downwards, allowing the hardware to move downwards towards the central polishing wheel 23 below. The hardware is then suspended above the central polishing wheel 23 by the support of the two support plates 43. The intelligent timer built into the electric lift 31 starts timing, and the drive motor 22 drives the spline shaft 21 to rotate the central polishing wheel 23 at high speed. The elastic stiffness of the rubber material used in the support plates 43 is lower than that of the compression spring 35. At this time, the worker only needs to... By gently pressing down on the hardware, the curved structure of the two support plates 43 can be easily stretched and bent downwards, causing deformation. The limiting rod 45 can limit the downward stretching stroke of the corresponding support plate 43, allowing the bottom of the hardware to smoothly contact the high-speed rotating central polishing wheel 23 for polishing. At the same time, the operator manually rotates the hardware around its own axis, allowing the hardware to polish while rotating, and causing the hardware to move back and forth between the two support plates 43 in the left and right direction. At the same time, according to the diameter of different areas of the hardware, the downward stretching of the support plates 43 caused by pressing down on the hardware is continuously adjusted, allowing the central polishing wheel 23 to smoothly contact each area of ​​the hardware for polishing.

[0036] When polishing the recessed corner areas where hardware parts connect, the worker presses down on one end of the hardware part. This causes the pressed end to rotate the supporting plate 43 on the same side, along with its connected fixing rod 42 and adapter block 41, around the axis of the adapter block 41. Simultaneously, the adapter block 41 drives the corresponding torsion spring 44 to twist, causing the other end of the hardware part to separate from the corresponding supporting plate 43 and be lifted upwards. This puts the hardware part in a tilted state with one end tilted upwards, allowing the worker to easily control the tilt. The hardware component is polished by aligning the recessed corner area of ​​the transition with the central polishing wheel 23. The hardware component is supported by the support plate 43. The operator only needs to press down on the hardware component to control the contact force with the central polishing wheel 23. There is no need to hold the hardware component in the air for the whole process, which greatly reduces hand fatigue. In the polishing process of the hardware component, while ensuring sufficient limiting support, more freedom is provided for the multi-angle fine control and adjustment of the hardware component, so that the polishing work of the hardware component can be completed more flexibly and efficiently.

[0037] After the intelligent timer built into the electric lift 31 finishes its current phase of timing, the electric lift 31 forcibly pushes the column 32 and the vertical slider 33 and the entire supporting assembly 4 connected to it upwards. At the same time, the vertical slider 33 pushes the bottom of the limit rod 45 to forcibly move the hardware upwards away from the central polishing wheel 23, reminding the workers to stop the current phase of polishing work, allowing the workers' hands to rest intermittently, and allowing the hardware and the central polishing wheel 23 to have sufficient time to cool down, waiting for the start of the next phase of polishing work.

[0038] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
