Description

Technical Field

[0001] This invention belongs to the field of polishing machine technology, specifically relating to an automatic consumable compensation polishing machine. Background Technology

[0002] Currently, most fully automatic polishing machines on the market use programmed numerical control for compensation, but due to limitations such as the material of the polishing belt, the process, and the irregular wear, it is difficult to achieve stable and accurate automatic compensation.

[0003] Especially in polishing non-planar workpieces, complex curved surfaces, or inclined surfaces, traditional polishing machines often require frequent manual intervention, making it difficult to maintain a constant contact pressure and wax spraying distance between the polishing belt and the workpiece. This results in problems such as large fluctuations in polishing quality, frequent replacement of consumables, and long downtime.

[0004] While there are disc-type polishing machines in the existing technology that achieve compensation through pressure regulation, their structure is usually only suitable for flat surface polishing or simple curved surfaces. They are difficult to adapt to the high-precision polishing requirements of multi-angle, multi-axis linkage, and real-time compensation. Especially under complex working conditions where the polishing belt wears rapidly and wax spraying and tension need to be adjusted synchronously, existing equipment generally lacks an integrated and linkage automatic adjustment mechanism. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic compensation polishing machine for consumables.

[0006] The technical solution adopted to solve the above technical problems is: an automatic consumable compensation polishing machine, including a machine body, a motor fixedly installed on the rear wall of the machine body, a drive wheel fixedly connected to the output end of the motor, a driven wheel one, a driven wheel two, and a tension wheel connected to the drive wheel through a polishing belt, the driven wheel two being located below the drive wheel, the driven wheel one and the tension wheel being located on the middle sides of the drive wheel and the driven wheel two respectively, a wax spray gun being provided on the outer side of the vertical section of the polishing belt, and a moving clamping device for driving the workpiece to move being provided below the polishing belt;

[0007] The front side of the machine body is also equipped with an automatic compensation component that drives the driven wheel two to move precisely, a coordinated adjustment component that cooperates with the driven wheel one to compensate, a wax spraying adjustment component that stabilizes the wax spraying distance of the wax spraying gun, and a tension adjustment component that adjusts the position of the tension wheel to realize the disassembly and assembly of the polishing belt. The automatic compensation component synchronously drives the coordinated adjustment component, the wax spraying adjustment component, and the tension adjustment component to produce corresponding adjustment actions.

[0008] Furthermore, the automatic compensation component includes a servo electric cylinder and a first limiting slide rail fixedly installed horizontally on the front wall of the machine body, and a second limiting slide rail fixedly installed vertically on the front wall of the machine body. The second limiting slide rail is vertically located below the first limiting slide rail. The movable end of the servo electric cylinder is fixedly connected to the first limiting slider. The side wall of the first limiting slider is slidably connected to the inner wall of the first limiting slide rail. The outer wall of the first limiting slider is rotatably connected to a connecting rod. The other end of the connecting rod is rotatably connected to a push rod. The outer wall of the push rod is fixedly installed with a first sliding seat. The side wall of the first sliding seat is in rolling contact with the inner wall of the second limiting slide rail. The end of the push rod near the driven wheel is provided with a compensation monitoring mechanism that achieves precise compensation through pressure monitoring. The compensation monitoring mechanism simultaneously monitors the wear of the polishing belt.

[0009] Through the above technical solution, when polishing the workpiece, the compensation monitoring mechanism monitors the polishing pressure in real time. As polishing progresses, the polishing belt gradually wears and thins. When the pressure in contact with the workpiece begins to decrease, the servo electric cylinder drive component performs a compensation action until the pressure monitored by the monitoring mechanism returns to the initial value, maintaining the stability of the polishing pressure and ensuring the consistency of the workpiece polishing quality. The polishing belt remains stable from brand new to its depletion, solving the quality fluctuation problem caused by traditional manual adjustment.

[0010] Furthermore, the compensation monitoring mechanism includes a sliding seat two that rolls in contact with the inner wall of the limiting slide rail two, a connecting plate fixed to one end of the push rod near the sliding seat two, and a magnetic grating ruler installed along the length of the limiting slide rail two on the inner wall of the limiting slide rail two. The outer wall of the sliding seat two is rotatably connected to both ends of the driven wheel two through a rotating frame. A pressure sensor is fixedly installed on the surface of the connecting plate. The sensing end of the pressure sensor is in contact with the surface of the sliding seat two. The connecting end of the pressure sensor is electrically connected to a low-pass filter. Several limiting rods are fixedly connected to the side wall of the sliding seat two facing the connecting plate. The other end of each limiting rod passes through the side wall of the connecting plate and is fixedly connected to a stop block. A spring is sleeved on the outer side of each limiting rod, and the spring is located between the connecting plate and the stop block. A reading head is fixedly installed on the side wall of the limiting slide rail two on the sliding seat two. The reading head corresponds to the position of the magnetic grating ruler.

[0011] Using the above technical solution, before polishing, an initial pressure value is preset. When monitoring the polishing pressure, a low-pass filter filters out high-frequency vibration interference during the polishing process, resulting in a smooth tension change signal. As the polishing belt gradually wears and thins during polishing, the pressure sensor senses that the pressure in contact with the workpiece begins to decrease. At this point, the servo electric cylinder can be activated to drive the components to perform a compensation action, re-tensioning the polishing belt and restoring the pressure sensor reading to near the initial value. In each compensation cycle, the driven wheel two moves upward precisely by a small compensation amount. Throughout the compensation process, the reading head continuously reads the position signal on the magnetic scale. When the cumulative displacement reaches the maximum allowable wear compensation amount of the polishing belt, the control system can issue an alarm, prompting the replacement of the polishing belt.

[0012] Furthermore, the coordinated adjustment component includes a rack one welded and fixed to one side wall of the limiting slider, and a limiting slide rail three horizontally fixedly installed on the front wall of the machine body. The inner side wall of the limiting slide rail three is slidably connected to a sliding seat three. The side wall of the rack one is slidably connected to the inner wall of the limiting slide rail one. The outer side wall of the sliding seat three is rotatably connected to both ends of the driven wheel one through a rotating frame. A rack two is welded and fixed to one end of the sliding seat three facing the rack one. A gear meshes and drives between the rack two and the rack one. The gear is rotatably installed on the front wall of the machine body through a rotating shaft.

[0013] Through the above technical solution, when the servo electric cylinder drives the limit slider one and rack one to move horizontally, rack one drives the gear to rotate clockwise, and the gear then drives rack two, which meshes with it, to move to the right. Since rack one and rack two are located on opposite sides of the gear, their directions of movement are always opposite, and their movement distances are strictly equal, thus maintaining the transmission stroke and tension of the polishing belt, perfectly maintaining the center position and verticality of the vertical working section of the polishing belt, and ensuring stable operation of the polishing operation.

[0014] Furthermore, the wax spraying adjustment assembly includes a right-angle connecting rod fixedly installed on the front wall of the rack and pinion, and a limiting slide rail four horizontally fixedly installed on the front wall of the machine body. A limiting slider two is fixedly connected to the side wall of the horizontal section of the right-angle connecting rod. The side wall of the limiting slider two is slidably connected to the inner wall of the limiting slide rail four. A mounting bracket is fixedly connected to the front wall of the right-angle connecting rod. The wax spraying gun is fixedly installed on the mounting bracket, and the nozzle of the wax spraying gun faces the outside of the vertical plane of the polishing belt.

[0015] Through the above technical solution, when the compensation action is performed, the servo electric cylinder pushes the limit slider to move to the left, and the rack and right-angle connecting rod move to the left simultaneously, which drives the mounting bracket and the wax spray gun to move closer to the surface of the polishing belt that is thinner and more inward. This automatically maintains the preset distance between the nozzle and the surface of the polishing belt, ensuring the quality and effect of waxing and improving the stability of the finished product quality.

[0016] Furthermore, the tension adjustment assembly includes a limiting shell vertically fixedly installed on the front wall of the machine body. A movable column is slidably connected through the side wall of the limiting shell. A rotating frame is fixedly connected to one end of the movable column. The tension wheel is rotatably installed in the rotating frame. A limiting groove is formed vertically through a portion of the movable column located in the limiting shell. A wedge-shaped limiting block is slidably provided inside the limiting shell. The inclined surface of the wedge-shaped limiting block slides in cooperation with the inner wall of the limiting groove. A spring is fixedly connected to the end of the wedge-shaped limiting block away from the driven wheel. A limiting tube is connected through the bottom end of the limiting shell. A linkage rod is slidably connected to the inner wall of the limiting tube. The end of the linkage rod away from the limiting tube is fixedly connected to the outer surface of the sliding seat.

[0017] With the above technical solution, when the polishing belt needs to be replaced, the servo electric cylinder retracts the movable rod, which drives the push rod and linkage rod to rise through the connecting rod. The linkage rod, through the limit tube, pushes the wedge-shaped limit block to rise completely, so that its inclined surface, in conjunction with the limit groove, drives the movable column to slide to the left, making the polishing belt completely loose, allowing the old belt to be easily removed and replaced with a new one. When a new polishing belt is replaced, the servo electric cylinder drives the linkage rod to fall, disengaging it from the wedge-shaped limit block. At this time, spring two pushes the wedge-shaped limit block to reset, so that its inclined surface, in conjunction with the limit groove, drives the movable column to slide to the right. The tensioning wheel, under the action of spring two, automatically pre-tensions the new polishing belt, significantly improving the overall efficiency of the equipment.

[0018] Furthermore, the mobile clamping device includes a lift fixedly installed on the upper surface of the bottom end of the machine body. An X-axis electric slide rail is fixedly installed on the top of the lift. A Z-axis electric slide rail is fixedly installed on the top of the drive slider of the X-axis electric slide rail. A workpiece clamp is fixedly installed on the top of the drive slider of the Z-axis electric slide rail.

[0019] Through the above technical solution, a closed-loop optimization is formed with the compensation system to maintain stable directional pressure. When the control terminal receives a signal that the polishing belt has been compensated to the limit, it can automatically command the moving clamping device to move the workpiece out of the polishing area and sound an alarm. At the same time, the workpiece movement trajectory can be programmed to achieve automated and uniform polishing of complex curved surfaces and irregularly shaped workpieces, thus expanding the processing capacity of the equipment.

[0020] Furthermore, the servo electric cylinder is electrically connected to an external control terminal, and the control terminal is electrically connected to a pressure sensor, a low-pass filter, a reading head, a wax spray gun, a lift, an X-axis electric slide rail, and a Z-axis electric slide rail.

[0021] Through the above technical solution, the control terminal can collect and process the signals from the pressure sensor and the reading head in real time; determine whether to trigger compensation based on the pressure signal, and instruct the servo electric cylinder to perform precise compensation actions; determine the remaining life of the polishing belt based on the cumulative displacement reading head signal, and provide an early warning before it is exhausted; coordinate and control the switching of the wax spray gun and the movement of each axis of the moving clamping device to realize a fully automatic polishing process; when executing the "belt changing mode", control the servo electric cylinder to retract to the limit position, triggering the rapid release function of the tension adjustment component.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) By setting automatic compensation components and collaborative adjustment components, a constant polishing line speed and contact pressure are maintained to ensure the polishing quality of the workpiece. The polishing belt remains stable from brand new to depletion, which solves the quality fluctuation problem caused by traditional manual adjustment. Pure mechanical linkage provides rapid response and avoids the cumulative error or response delay that may occur with multiple independent actuators, thus ensuring the stability of the polishing quality of the workpiece.

[0024] (2) By setting the wax spraying adjustment component and cooperating with the automatic compensation component, the absolute synchronization relationship between each wheel position and the wax spraying gun position is ensured, the preset distance between the wax spraying gun and the polishing belt surface remains unchanged, the quality and effect of waxing are guaranteed, and the stability of the finished product quality is improved.

[0025] (3) By setting the tension adjustment component and cooperating with the automatic compensation component, "one-click tensioning" is realized, which shortens the belt changing time from several minutes to more than ten seconds, reduces downtime, and significantly improves the overall efficiency of the equipment;

[0026] (4) By using the servo electric cylinder, polishing belt compensation, coordinated wheel position adjustment, wax spraying distance adjustment and tension wheel tension adjustment can be realized simultaneously with only one servo electric cylinder drive. It has a compact structure, fast response, no cumulative error, and is suitable for high-precision polishing requirements.

[0027] (5) Through the set moving clamping device, its multi-axis linkage and real-time compensation of the polishing belt make the polishing belt contact the workpiece at a specific angle, which is suitable for high-quality polishing of non-planar workpieces such as molds, irregular parts, and decorative parts.

[0028] (6) A real-time monitoring system is constructed by setting pressure sensors, magnetic scales, low-pass filters and reading heads to achieve accurate measurement and early warning of the wear of polishing belts and support predictive maintenance. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] like Figures 1-10 As shown, an automatic compensation polishing machine for consumables in this embodiment includes a machine body 1. A motor 2 is fixedly installed on the rear wall of the machine body 1. A drive wheel 3 is fixedly connected to the output end of the motor 2. The drive wheel 3 is connected to a driven wheel 4, a driven wheel 5, and a tension wheel 6 via a polishing belt 12. The driven wheel 5 is located below the drive wheel 3. The driven wheel 4 and the tension wheel 6 are located on the middle sides of the drive wheel 3 and the driven wheel 5, respectively. A wax spray gun 7 is provided on the outer side of the vertical section of the polishing belt 12. A moving clamping device 13 for driving the workpiece to move is provided below the polishing belt 12.

[0042] The front side of the machine body 1 is also equipped with an automatic compensation component 8 that drives the driven wheel 2 5 to move precisely, a coordinated adjustment component 9 that coordinates with the driven wheel 1 4 to compensate, a wax spraying adjustment component 10 that stabilizes the wax spraying distance of the wax spraying gun 7, and a tension adjustment component 11 that adjusts the position of the tension wheel 6 to realize the disassembly and assembly of the polishing belt 12. The automatic compensation component 8 synchronously drives the coordinated adjustment component 9, the wax spraying adjustment component 10, and the tension adjustment component 11 to produce corresponding adjustment actions.

[0043] like Figures 3-5 As shown, the automatic compensation component 8 includes a servo cylinder 801 and a limiting slide rail 1 802 that are horizontally fixedly installed on the front wall of the machine body 1, and a limiting slide rail 2 805 that is vertically fixedly installed on the front wall of the machine body 1. The limiting slide rail 2 805 is vertically located below the limiting slide rail 1 802. The movable end of the servo cylinder 801 is fixedly connected to the limiting slider 1 803. The side wall of the limiting slider 1 803 is slidably connected to the inner wall of the limiting slide rail 1 802. The outer wall of the limiting slider 1 803 is rotatably connected to the connecting rod 804. The other end of the connecting rod 804 is rotatably connected to the push rod 806. The outer wall of the push rod 806 is fixedly installed with the sliding seat 1 807. The side wall of the sliding seat 1 807 is in rolling contact with the inner wall of the limiting slide rail 2 805. The end of the push rod 806 near the driven wheel 2 5 is provided with a compensation monitoring mechanism 808 that achieves precise compensation through pressure monitoring. The compensation monitoring mechanism 808 simultaneously monitors the wear of the polishing belt 12.

[0044] When polishing the workpiece, the compensation monitoring mechanism 808 monitors the polishing pressure in real time. As polishing progresses, the polishing belt 12 gradually wears and thins. When the pressure of the workpiece in contact begins to decrease, the servo electric cylinder 801 drive assembly performs a compensation action.

[0045] During compensation, the servo cylinder 801 drives the limit slider 803 to move horizontally. Through the transmission of the connecting rod 804, the horizontal motion is converted into the vertical downward motion of the push rod 806, which drives the sliding seat 807 to slide along the limit rail 805. At the same time, it drives the driven wheel 5 to move downward precisely, pushing the polishing belt 12 to contact the workpiece until the pressure monitored by the compensation monitoring mechanism 808 returns to the initial value, maintaining the stability of the polishing pressure and ensuring the consistency of the workpiece polishing quality. The polishing belt 12 remains stable from its initial state until it is exhausted, solving the quality fluctuation problem caused by traditional manual adjustment.

[0046] like Figures 4-5As shown, the compensation monitoring mechanism 808 includes a sliding seat 8081 that rolls in contact with the inner wall of the limiting slide rail 805, a connecting plate 8082 fixed to one end of the push rod 806 near the sliding seat 8081, and a magnetic scale 8088 installed along the length of the limiting slide rail 805 on the inner wall of the limiting slide rail 805. The outer wall of the sliding seat 8081 is rotatably connected to both ends of the driven wheel 5 via a rotating frame. A pressure sensor 8086 is fixedly mounted on the surface of the connecting plate 8082. The sensing end of the pressure sensor 8086 is in contact with the surface of the sliding seat 8081. The connection end of 86 is electrically connected to a low-pass filter 8087. Several limiting rods 8083 are fixedly connected to the side wall of the sliding seat 8081 facing the connecting plate 8082. The other end of each limiting rod 8083 passes through the side wall of the connecting plate 8082 and is fixedly connected to a stop block 8085. A spring 8084 is sleeved on the outside of each limiting rod 8083, and the spring 8084 is located between the connecting plate 8082 and the stop block 8085. A reading head 8089 is fixedly installed on the side wall of the sliding seat 8081 located on the limiting slide rail 805. The reading head 8089 corresponds to the position of the magnetic scale 8088.

[0047] Before polishing, driven wheel 2 5 presses the workpiece with polishing belt 12, driving sliding seat 2 8081 to slide upward along limit slide rail 2 805. Sliding seat 2 8081 squeezes the sensing end of pressure sensor 8086 and presets the initial pressure value.

[0048] The elastic force of spring 8084, combined with the limiting rod 8083, keeps the pressure sensor 8086 in close contact with the sliding seat 8081, preventing dust particles from adhering to the sensing end of the pressure sensor 8086 during polishing and affecting its normal use. At the same time, the elastic pre-compression system can not only transmit pressure signals but also absorb instantaneous impacts during the polishing process, protecting the sensor and maintaining system stability.

[0049] When monitoring the polishing pressure, the low-pass filter 8087 filters out high-frequency vibration interference during the polishing process, obtaining a smooth tension change signal. As the polishing belt 12 gradually wears and thins during polishing, the pressure sensor 8086 senses that the pressure in contact with the workpiece begins to decrease. At this time, the servo cylinder 801 can be activated to drive the components to perform compensation actions, re-tensioning the polishing belt 12, so that the reading of the pressure sensor 8086 returns to near the initial value. In each compensation cycle, the driven wheel 5 moves upward precisely by a small compensation amount ΔH. Throughout the compensation process, the reading head 8089 continuously reads the position signal on the magnetic scale 8088.

[0050] The cumulative displacement ΣΔH = H_current - H0 from the initial position H0 to the current position H_current directly and accurately reflects the total wear thickness of the polishing belt 12. When the cumulative displacement reaches the maximum allowable wear compensation amount of the polishing belt 12 (corresponding to H_max), the control system can issue an alarm to prompt the replacement of the polishing belt 12, providing a data basis for predictive maintenance and consumable life management.

[0051] like Figure 6 As shown, the coordinated adjustment component 9 includes a rack 901 welded and fixed to the side wall of the limiting slider 803, and a limiting slide rail 902 horizontally fixedly installed on the front wall of the body 1. The inner side wall of the limiting slide rail 902 is rotatably connected to a sliding seat 903. The side wall of the rack 901 is slidably connected to the inner wall of the limiting slide rail 802. The outer side wall of the sliding seat 903 is rotatably connected to both ends of the driven wheel 4 through a rotating frame. A rack 904 is welded and fixed to one end of the sliding seat 903 facing the rack 901. A gear 905 meshes and drives between the rack 904 and the rack 901. The gear 905 is rotatably installed on the front wall of the body 1 through a rotating shaft.

[0052] In order to ensure that the vertical working section of the polishing belt 12 remains vertical and relatively fixed in position when the driven wheel 2 5 moves downward to compensate, the position of the driven wheel 4 must be adjusted synchronously.

[0053] When the servo cylinder 801 drives the limit slider 803 and rack 901 to move horizontally, rack 901 drives gear 905 to rotate clockwise, and gear 905 then drives rack 904, which meshes with it, to move to the right. Since rack 901 and rack 904 are located on opposite sides of gear 905, their directions of movement are always opposite, and their movement distances are strictly equal.

[0054] This ensures that when driven wheel 2 5 moves downward to compensate ΔH, driven wheel 1 4 moves precisely to the right by ΔH through sliding seat 3 903, maintaining the transmission stroke and tension of polishing belt 12, perfectly maintaining the center position and verticality of the vertical working section of polishing belt 12, and ensuring stable operation of polishing work.

[0055] like Figure 7 As shown, the wax spraying adjustment assembly 10 includes a right-angle connecting rod 1001 fixedly installed on the front wall of rack 901 and a limiting slide rail 1002 fixedly installed laterally on the front wall of the body 1. A limiting slider 1003 is fixedly connected to the side wall of the horizontal section of the right-angle connecting rod 1001. The side wall of the limiting slider 1003 is slidably connected to the inner wall of the limiting slide rail 1002. A mounting bracket 1004 is fixedly connected to the front wall of the right-angle connecting rod 1001. The wax spraying gun 7 is fixedly installed on the mounting bracket 1004. The nozzle of the wax spraying gun 7 faces the outside of the vertical plane of the polishing belt 12.

[0056] When the compensation action is performed, the servo electric cylinder 801 pushes the limit slider 803 to move to the left, and the rack 901 and the right-angle connecting rod 1001 move to the left in sync. This causes the mounting bracket 1004 and the wax spray gun 7 to move closer to the surface of the polishing belt 12, which is located further inside after the waxing is thinned. This automatically maintains the preset distance between the nozzle and the surface of the polishing belt 12. No matter how the polishing belt is worn and compensated, the distance between the wax spray nozzle and the surface of the polishing belt remains unchanged, ensuring the atomization effect and spray area of ​​the polishing wax are stable, guaranteeing the quality and effect of waxing, and improving the stability of the finished product quality.

[0057] like Figures 8-9 As shown, the tension adjustment assembly 11 includes a limiting shell 1103 vertically fixedly installed on the front wall of the machine body 1. A movable column 1101 is slidably connected through the side wall of the limiting shell 1103. One end of the movable column 1101 is fixedly connected to a rotating frame 1102. The tensioning wheel 6 is rotatably installed in the rotating frame 1102. A limiting groove 1106 is formed in the vertical part of the movable column 1101 located in the limiting shell 1103. A wedge-shaped groove is slidably provided inside the limiting shell 1103. The wedge-shaped limiting block 1104 has a slidable engagement between its inclined surface and the inner wall of the limiting groove 1106. A spring 1105 is fixedly connected to the end of the wedge-shaped limiting block 1104 away from the driven wheel 5. A limiting tube 1107 is connected through the bottom end of the limiting shell 1103. A linkage rod 1108 is slidably connected to the inner wall of the limiting tube 1107. The end of the linkage rod 1108 away from the limiting tube 1107 is fixedly connected to the outer surface of the sliding seat 807.

[0058] During the polishing process, the tensioning wheel 6 and the driven wheel 5 work together to achieve tension while keeping one side of the polishing belt 12 perpendicular to the bottom of the machine body 1, ensuring the stability of the wax spraying by the wax spraying gun 7.

[0059] When the polishing belt 12 needs to be replaced, the servo cylinder 801 retracts the movable rod, which drives the push rod 806 and the linkage rod 1108 to rise through the connecting rod 804. The linkage rod 1108 pushes the wedge-shaped limiting block 1104 to rise completely through the limiting tube 1107, so that its inclined surface cooperates with the limiting groove 1106 to drive the movable column 1101 to slide to the left, which drives the tensioning wheel 6 to move far away from the center of the polishing belt 12 loop, so that the polishing belt 12 is completely relaxed, and the old belt can be easily removed and replaced with a new belt.

[0060] After replacing the new polishing belt 12, the servo cylinder 801 drives the linkage rod 1108 to descend, causing it to disengage from the wedge-shaped limit block 1104. At this time, the second spring 1105 pushes the wedge-shaped limit block 1104 to reset, so that its inclined surface cooperates with the limit groove 1106 to drive the movable column 1101 to slide to the right. Under the action of the second spring 1105, the tensioning wheel 6 automatically pre-tensions the new polishing belt 12, realizing "one-click tensioning and loosening", reducing the belt replacement time from several minutes to more than ten seconds, and significantly improving the overall efficiency of the equipment.

[0061] like Figure 10 As shown, the mobile clamping device 13 includes a lift 1301 fixedly installed on the upper surface of the bottom end of the machine body 1. An X-axis electric slide rail 1302 is fixedly installed on the top of the lift 1301. A Z-axis electric slide rail 1303 is fixedly installed on the top of the drive slider of the X-axis electric slide rail 1302. A workpiece clamp 1304 is fixedly installed on the top of the drive slider of the Z-axis electric slide rail 1303.

[0062] The lifting platform 1301, the X-axis electric slide rail 1302, and the Z-axis electric slide rail 1303 work together to enable the workpiece to perform three-dimensional precise movement, forming a closed-loop optimization with the compensation system to maintain stable directional pressure.

[0063] When the control terminal receives a signal that the polishing belt 12 has been compensated to its limit, it can automatically command the moving clamping device 13 to move the workpiece out of the polishing area and trigger an alarm, thus realizing safe operation and production continuity management under unattended operation. At the same time, the workpiece movement trajectory can be programmed to achieve automated and uniform polishing of complex curved surfaces and irregularly shaped workpieces, thereby expanding the processing capabilities of the equipment.

[0064] like Figures 1-10 As shown, the servo electric cylinder 801 is electrically connected to the peripheral control terminal, and the control terminal is electrically connected to the pressure sensor 8086, the low-pass filter 8087, the reading head 8089, the wax spray gun 7, the elevator 1301, the X-axis electric slide rail 1302, and the Z-axis electric slide rail 1303.

[0065] The control terminal can acquire and process signals from pressure sensor 8086 and reading head 8089 in real time;

[0066] The system determines whether compensation should be triggered based on the pressure signal and instructs the servo electric cylinder 801 to perform precise compensation actions.

[0067] The remaining lifespan of the polishing belt 12 is determined based on the cumulative displacement reading head 8089 signal, and an early warning is issued before it is exhausted.

[0068] The switch of the wax spray gun 7 and the movement of each axis of the moving clamping device 13 are coordinated and controlled to achieve a fully automatic polishing process;

[0069] When executing the "belt changing mode", the control servo cylinder 801 is retracted to the limit position, triggering the rapid release function of the tension adjustment component 11.

[0070] The working principle of this embodiment is as follows: When in use, the workpiece clamp 1304 clamps and fixes the workpiece. Next, the workpiece is precisely moved and pressed against the polishing belt 12 by controlling the terminal elevator 1301, the X-axis electric slide rail 1302, and the Z-axis electric slide rail 1303.

[0071] At this time, driven wheel 2 5, in conjunction with polishing belt 12, presses the workpiece, causing sliding seat 2 8081 to slide upward along limit slide rail 2 805. Sliding seat 2 8081 squeezes the sensing end of pressure sensor 8086, presets the initial pressure value.

[0072] During polishing, motor 2 drives drive wheel 3 to rotate, which in turn drives driven wheel 1 4, driven wheel 2 5, and tension wheel 6 to rotate polishing belt 12 to polish the surface of the workpiece.

[0073] Meanwhile, when the pressure of polishing is monitored, the low-pass filter 8087 filters out the high-frequency vibration interference during the polishing process and obtains a smooth tension change signal. As the polishing belt 12 gradually wears and thins with polishing, the pressure sensor 8086 senses that the pressure in contact with the workpiece begins to decay. At this time, the servo electric cylinder 801 can be activated to drive the components to perform compensation actions.

[0074] During compensation, the servo cylinder 801 drives the limit slider 803 to move horizontally. Through the transmission of the connecting rod 804, the horizontal motion is converted into the vertical downward motion of the push rod 806, which drives the sliding seat 807 to slide along the limit rail 805. At the same time, it drives the driven wheel 5 to move downward precisely, pushing the polishing belt 12 to contact the workpiece, re-tensioning the polishing belt 12, so that the reading of the pressure sensor 8086 returns to near the initial value, maintaining the stability of the polishing pressure and ensuring the consistency of the workpiece polishing quality.

[0075] In each compensation cycle, driven wheel 2 5 moves upward precisely by a small compensation amount ΔH. Throughout the compensation process, the reading head 8089 continuously reads the position signal on the magnetic scale 8088. The cumulative displacement ΣΔH = H_current - H0 from the initial position H0 to the current position H_current directly and accurately reflects the total wear thickness of the polishing belt 12. When the cumulative displacement reaches the maximum allowable wear compensation amount of the polishing belt 12, the control system can issue an alarm and command the moving clamping device 13 to move the workpiece out of the polishing area.

[0076] During the compensation process, when the servo cylinder 801 drives the limit slider 803 and rack 901 to move horizontally, rack 901 drives gear 905 to rotate clockwise, and gear 905 then drives rack 904, which meshes with it, to move to the right. Since rack 901 and rack 904 are located on opposite sides of gear 905, their directions of movement are always opposite, and their movement distances are strictly equal, thus maintaining the transmission stroke and tension of polishing belt 12 and maintaining the center position and verticality of the vertical working section of polishing belt 12.

[0077] At the same time, the servo electric cylinder 801 pushes the limit slider 803 to move to the left, and the rack 901 and the right-angle connecting rod 1001 move to the left in sync, driving the mounting bracket 1004 and the wax spray gun 7 to approach the surface of the polishing belt 12, which is located further inside after the thinning, so as to automatically maintain the preset distance between the nozzle and the surface of the polishing belt 12, ensuring the quality and effect of waxing.

[0078] When the polishing belt 12 is replaced, the servo cylinder 801 retracts the movable rod, which moves to the right. This moves the rod to the right, and through the connecting rod 804, it drives the push rod 806 and the linkage rod 1108 to rise. The linkage rod 1108 pushes the wedge-shaped limit block 1104 to rise completely through the limit tube 1107. This causes the inclined surface of the wedge to cooperate with the limit groove 1106 to move the movable column 1101 to the left, which drives the tension wheel 6 to move significantly away from the center of the polishing belt 12 loop. This completely relaxes the polishing belt 12, making it easy to remove the old belt and replace it with a new one.

[0079] After replacing the new polishing belt 12, the servo cylinder 801 extends the movable rod, which moves to the left, causing the push rod 806 and the linkage rod 1108 to descend, disengaging them from contact with the wedge-shaped limiting block 1104. At this time, the second spring 1105 pushes the wedge-shaped limiting block 1104 to reset, so that its inclined surface cooperates with the limiting groove 1106 to drive the movable column 1101 to slide to the right. Under the action of the second spring 1105, the tensioning wheel 6 automatically pre-tensions the new polishing belt 12, realizing "one-click tensioning".

[0080] In summary, this invention achieves full automation of the entire process from polishing belt wear compensation, wax spraying distance maintenance, tension adjustment to belt changing operation through the deep integration of mechanical linkage and intelligent monitoring. It adapts to the high-precision polishing requirements of multi-angle, multi-axis linkage and real-time compensation, and is particularly suitable for polishing processing scenarios of small batches, multiple varieties, high precision and non-standardized workpieces. It has strong engineering applicability and technological advancement.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
