Description

TECHNICAL FIELD

[0001] The application relates to the technical field of brake hub polishing, in particular to a height self-adaptive grinding machine for ship brake hub machining. BACKGROUND

[0002] The ship winch is a key equipment on the ship and plays a vital role in mooring, towing and anchor lifting of the ship. The brake hub is a core component of the brake system of the ship winch, and the performance of the brake hub directly affects the braking effect and safety of the ship winch. In the production process of the brake hub, due to the limitations of casting and machining processes, various defects such as uneven roughness and size precision deviation often exist on the surface of the brake hub. These defects not only affect the friction between the brake hub and the brake pad, reduce the braking effect, but also cause abnormal wear of the brake pad and shorten the service life of the brake pad. In the maintenance of the brake hub, the traditional manual polishing method is low in efficiency, high in labor intensity and difficult to guarantee the polishing quality, and cannot meet the high reliability requirement of the ship winch brake system. The existing brake hub polishing usually adopts a grinding machine, such as a ship winch brake hub polishing device disclosed in CN212735308U. In use, the grinding wheel is rotated by the rotating shaft to polish the main body. The operator moves the first sliding block and the first screw rod forward and backward by the hand wheel, and moves the second sliding block and the second screw rod to move the movable plate in the left and right directions. However, the size and height (thickness) of the winch brake hub are not uniform, so that the driving device needs to be adjusted or replaced in time to control the moving range of the grinding wheel when polishing the brake drum with different heights (thicknesses), which not only affects the processing efficiency, but also increases the processing cost. SUMMARY

[0003] The application aims to solve the problems in the background art and provides a height self-adaptive grinding machine for ship brake hub machining.

[0004] To achieve the above-mentioned purpose, the application adopts the following technical scheme:

[0007] The upper side of the workbench is movably provided with a clamping assembly, the clamping assembly is used for fixing and driving the brake hub to rotate.

[0008] In the height-adaptive grinding machine for ship brake hub machining, the inner side of the workbench is fixedly provided with an electric push rod, the bottom of the sliding frame is integrally formed with a support, the output end of the electric push rod is fixedly connected with the support, and the two sliding plates and the sliding frame are both provided with spring I.

[0009] In the height-adaptive grinding machine for ship brake hub machining, the bottom of the lower sliding plate is fixedly provided with a motor II, the output shaft of the motor II is fixedly connected with the rotating rod I, and the bottom of the rotating rod II is provided with a speed reducer connected with the output shaft of the motor II.

[0010] In the height-adaptive grinding machine for ship brake hub machining, the grinding wheel is rotatably arranged in the sliding cover, the sliding block and the inner side of the sliding cover are provided with spring II, the side wall of the sliding block is welded with a cleaning piece, the cleaning piece is located on the inner side of the sliding cover, and the cleaning piece is in abutment with the grinding wheel.

[0011] In the height-adaptive grinding machine for ship brake hub machining, the side wall of the sliding cover is provided with a plurality of uniformly distributed air inlet grooves and three uniformly distributed air outlet grooves, the side wall of each air outlet groove is integrally formed with a baffle, the air inlet grooves and the air outlet grooves are inclined, the inclination angle of the air inlet grooves is the same as the rotating direction of the grinding wheel, and the inclination angle of the air outlet grooves is opposite to the rotating direction of the grinding wheel.

[0012] In the height-adaptive grinding machine for ship brake hub machining, the clamping assembly comprises a clamping rod, a clamping strip and a sliding ring, the clamping rod is rotatably arranged on the top of the workbench, the clamping strip is slidably arranged on the side wall of the clamping rod, and the sliding ring is slidably arranged in the clamping rod, the inner side of the workbench is slidably provided with a spring lock block, the side wall of the clamping rod is provided with a lock groove, and the spring lock block is slidably inserted into the inner side of the lock groove.

[0013] In the aforementioned height-adaptive grinding machine for machining ship brake hubs, a motor is fixedly installed inside the worktable, and a lead screw is fixedly connected to the output shaft of the motor. A sliding ring is movably fitted onto the outside of the lead screw, and the sliding ring and the lead screw are threadedly connected.

[0014] In the aforementioned height-adaptive grinding machine for machining ship brake hubs, the side wall of the clamping bar is provided with an inclined surface, and the side wall of the sliding ring is integrally formed with an inclined block, the inclined block and the inclined surface abut against each other.

[0015] Compared with existing technologies, the advantages of this invention are:

[0016] 1. The sliding frame is moved to the set position by the electric push rod. During the grinding process of the brake drum, the sliding plate moves against the brake drum through the spring, so that the grinding wheel always keeps in contact with the brake drum for grinding, which improves the grinding efficiency of the brake drum. The rotating rod drives the sliding cover to slide up and down reciprocally through the bidirectional sliding groove and the slider. The grinding wheel follows the sliding cover to slide up and down reciprocally. The reciprocating up and down sliding of the grinding wheel expands the grinding range of the brake drum and further improves the grinding efficiency of the brake drum.

[0017] 2. When the grinding wheel touches the edge of the brake drum, the slider compresses and retracts the second spring. When the side wall of the other groove of the bidirectional groove aligns with the ball bearing, the second spring releases and the slider pops out. At this time, the rotating rod drives the sliding cover to move in the opposite direction through the bidirectional groove. The reversal is achieved by the retraction and popping of the slider, so that when the grinding wheel grinds brake drums of different heights, there is no need to adjust or change the drive equipment. This improves the applicability of the grinding wheel and reduces the time for reversal adjustment, thereby improving the efficiency of grinding brake drums.

[0018] 3. During the process of the slider compressing the spring and retracting, the slider drives the cleaning plate to contact the side wall of the grinding wheel and clean the grinding debris on the side wall of the grinding wheel, causing the grinding debris to loosen and fall off. During the rotation of the grinding wheel, outside air enters the interior of the sliding cover to form an airflow and dissipate heat from the grinding wheel. When the airflow contacts the baffle, the airflow forms a vortex between the baffle and the grinding wheel, and cleans the loose grinding debris on the side wall of the grinding wheel. Through the contact of the cleaning plate and the vortex formed by the airflow, the cleaning plate and the airflow clean the grinding wheel, improve the grinding effect of the grinding wheel, and prevent the grinding debris from clogging the pores on the side wall of the grinding wheel and affecting the grinding effect. At the same time, the airflow dissipates heat from the grinding wheel, increasing the life of the grinding wheel. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Reference Figure 1 - Figure 9As shown, a height-adaptive grinding machine for machining ship brake hubs includes a worktable 1 and a brake hub 11. A grinding assembly is movably mounted on the top of the worktable 1. The grinding assembly includes a sliding frame 21, a grinding wheel 217, and two sliding plates 211. A groove 13 is provided on the top of the worktable 1. The sliding frame 21 is slidably mounted inside the groove 13. The two sliding plates 211 are slidably mounted on the side wall of the sliding frame 21. A rotating rod 216 is rotatably mounted between the two sliding plates 211. The grinding wheel 217 is slidably inserted into the outside of the rotating rod 216.

[0032] An adaptive component is movably mounted on the outer side of the grinding wheel 217. The adaptive component includes a sliding cover 31, a slider 313, and a rotating rod 312. The rotating rod 312 is rotatably connected to two sliding plates 211. The slider 313 is slidably mounted inside the sliding cover 31. The sliding cover 31 is movably fitted onto the outer side of the rotating rod 312. A bidirectional groove 311 is provided on the outer peripheral wall of the rotating rod 312. The slider 313 and the rotating rod 312 abut against each other. A sliding ball is integrally formed on the side wall of the slider 313. The sliding ball is slidably mounted inside the bidirectional groove 311.

[0033] A clamping assembly is movably mounted above the worktable 1. The clamping assembly is used to fix and drive the brake drum 11 to rotate.

[0034] like Figure 2 and Figure 6 As shown, an electric actuator 213 is fixedly installed inside the workbench 1, and a bracket 214 is integrally formed at the bottom of the sliding frame 21. The output end of the electric actuator 213 is fixedly connected to the bracket 214, and a spring 212 is provided between the two sliding plates 211 and the sliding frame 21.

[0035] like Figure 2 and Figure 4 As shown, a second motor 215 is fixedly installed at the bottom of the sliding plate 211 located below. The output shaft of the second motor 215 is fixedly connected to the first rotating rod 216. A reducer 218 is provided between the bottom of the second rotating rod 312 and the output shaft of the second motor 215.

[0036] In this process, after the clamping assembly fixes the brake hub 11, the electric push rod 213 and the second electric motor 215 are activated. The electric push rod 213 pulls the sliding frame 21. After the sliding frame 21 drives the grinding wheel 217 to contact the brake hub 11, the electric push rod 213 continues to pull the sliding frame 21, causing the sliding plate 211 to compress the first spring 212. When the sliding frame 21 moves to the set position, the electric push rod 213 is turned off, and the second electric motor 215 drives the grinding wheel 217 to rotate, so that the grinding wheel 217 grinds the brake hub 11. By pulling the sliding frame 21 to the set position in one go by the electric push rod 213, the grinding wheel 217 moves towards the brake hub 11 by contacting the sliding plate 211 through the first spring 212 during the grinding process, so that the grinding wheel 217 always contacts the brake hub 11 for grinding, thereby improving the grinding efficiency of the brake hub 11.

[0037] like Figure 5 and Figure 8 As shown, the grinding wheel 217 is rotatably mounted inside the sliding cover 31. The slider 313 and the sliding cover 31 are equipped with a spring 314. A cleaning plate 315 is welded to the side wall of the slider 313. The cleaning plate 315 is located inside the sliding cover 31 and abuts against the grinding wheel 217.

[0038] During the grinding process of the grinding wheel 217 on the brake hub 11, the rotating rod 216 drives the rotating rod 312 to rotate through the reducer 218. This causes the rotating rod 312 to drive the sliding cover 31 to slide back and forth through the bidirectional sliding groove 311 and the slider 313. The grinding wheel 217 follows the sliding cover 31 to slide back and forth. By sliding the grinding wheel 217 back and forth, the grinding range of the grinding wheel 217 on the brake hub 11 is expanded, further improving the grinding efficiency of the brake hub 11.

[0039] Further reference Figure 5 and Figure 8 To explain, during the sliding process of the sliding cover 31 driven by the rotating rod 312, when the grinding wheel 217 abuts against the edge of the brake drum 11, the side wall of one of the two-way sliding grooves 311 abuts against the ball bearing, causing the slider 313 to compress the spring 314 and retract. When the side wall of the other sliding groove of the two-way sliding groove 311 corresponds to the ball bearing, the spring 314 releases and ejects the slider 313. At this time, the rotating rod 312 drives the sliding cover 31 to move in the opposite direction through the two-way sliding groove 311. The reversal is achieved by the retraction and ejection of the slider 313, so that when the grinding wheel 217 grinds brake drums 11 of different heights, there is no need to adjust or change the drive equipment. This improves the applicability of the grinding wheel 217 and reduces the time for reversal adjustment, thereby improving the efficiency of grinding the brake drum 11.

[0040] like Figure 8As shown, the side wall of the sliding cover 31 is provided with several evenly distributed air inlet slots 316 and three evenly distributed air outlet slots 318. Each air outlet slot 318 has a baffle 317 integrally formed on its side wall. Both the air inlet slots 316 and the air outlet slots 318 are inclined. The inclination angle of the air inlet slot 316 is the same as the rotation direction of the grinding wheel 217, and the inclination angle of the air outlet slot 318 is opposite to the rotation direction of the grinding wheel 217.

[0041] During the process of slider 313 compressing and retracting spring 314, slider 313 drives cleaning plate 315 to move, causing cleaning plate 315 to abut against the side wall of grinding wheel 217 and clean the grinding debris on the side wall of grinding wheel 217, causing the grinding debris on the side wall of grinding wheel 217 to loosen and fall off. During the rotation of grinding wheel 217, outside air enters the interior of sliding cover 31 through air inlet slot 316 to form airflow. The airflow moves with grinding wheel 217 and dissipates heat from grinding wheel 217. When the airflow is discharged from the sliding cover 31 through the exhaust channel 318, the airflow forms a vortex between the baffle 317 and the grinding wheel 217, and cleans the loose grinding debris on the side wall of the grinding wheel 217. The vortex formed by the contact of the cleaning plate 315 and the airflow cleans the grinding wheel 217, improves the grinding effect of the grinding wheel 217, and prevents the grinding debris from clogging the pores on the side wall of the grinding wheel 217 and affecting the grinding effect. At the same time, the airflow dissipates heat from the grinding wheel 217, improving the life of the grinding wheel 217.

[0042] like Figures 1-3 and Figure 9 As shown, the clamping assembly includes a clamping rod 12, a clamping bar 121, and a sliding ring 126. The clamping rod 12 is rotatably mounted on the top of the worktable 1. The clamping bar 121 is slidably mounted on the side wall of the clamping rod 12. The sliding ring 126 is slidably mounted inside the clamping rod 12. A spring locking block 124 is slidably mounted inside the worktable 1. A locking groove 127 is provided on the side wall of the clamping rod 12. The spring locking block 124 is slidably inserted into the inside of the locking groove 127.

[0043] like Figure 3 and Figure 9 As shown, a motor 123 is fixedly installed inside the workbench 1. The output shaft of the motor 123 is fixedly connected to a lead screw 122. A sliding ring 126 is movably fitted on the outside of the lead screw 122. The sliding ring 126 and the lead screw 122 are threadedly connected. The side wall of the clamping bar 121 is provided with an inclined surface 125. The side wall of the sliding ring 126 is integrally formed with an inclined block 128. The inclined block 128 and the inclined surface 125 abut against each other.

[0044] After the brake hub 11 is placed above the worktable 1, the motor 123 is started. At this time, the spring locking block 124 is located inside the locking groove 127. The motor 123 drives the lead screw 122 to rotate. The lead screw 122 drives the sliding ring 126 to move upward. The sliding ring 126 drives the clamping bar 121 to move outward of the clamping rod 12 through the inclined block 128 and the inclined surface 125. When the clamping bar 121 touches the inner wall of the brake hub 11, the sliding ring 126 stops sliding, the spring locking block 124 retracts, so that the sliding ring 126 drives the clamping rod 12 to rotate with the lead screw 122.

[0045] The working principle and usage of this invention are explained in detail below: After the brake hub 11 is placed above the workbench 1, the motor 123 starts and drives the lead screw 122 to rotate, causing the sliding ring 126 to move upward and driving the clamping bar 121 to move outward of the clamping rod 12. When the clamping bar 121 touches the inner wall of the brake hub 11, the sliding ring 126 drives the clamping rod 12 to rotate with the lead screw 122. At this time, the electric push rod 213 and the second motor 215 start. After the electric push rod 213 pulls the sliding frame 21 to the set position, the electric push rod 213 closes. At this time, the sliding plate 211 compresses the first spring 212, and the second motor 215 drives the grinding wheel 217 to rotate, so that the grinding wheel 217 presses against the brake hub. 11. Grinding is performed by moving the sliding plate 211 against the brake hub 11 via spring 212, ensuring that the grinding wheel 217 always contacts the brake hub 11 for grinding, thus improving the grinding efficiency of the brake hub 11. During the grinding process of the grinding wheel 217 on the brake hub 11, the rotating rod 216 drives the rotating rod 312 to rotate via the reducer 218, causing the rotating rod 312 to drive the sliding cover 31 to slide up and down reciprocally. The grinding wheel 217 follows the sliding cover 31 in the same reciprocating up and down motion. This reciprocating up and down motion of the grinding wheel 217 expands the grinding range of the brake hub 11, further improving the grinding efficiency of the brake hub 11. During the process of the rotating rod 312 driving the sliding cover 31 to slide, when the grinding wheel... When wheel 217 contacts the edge of brake drum 11, slider 313 compresses spring 314 and retracts. At this time, slider 313 drives cleaning plate 315 to move, causing cleaning plate 315 to contact the side wall of grinding wheel 217 and clean the grinding debris on the side wall of grinding wheel 217, making the grinding debris on the side wall of grinding wheel 217 loose and fall off. When the side wall of the other groove of the bidirectional groove 311 corresponds to the ball bearing, spring 314 releases and slides slider 313 pops out. At this time, rotating rod 312 drives sliding cover 31 to move in the opposite direction through bidirectional groove 311. The reversal is achieved by the retraction and popping of slider 313, so that when grinding wheel 217 grinds brake drum 11 of different heights, there is no need to adjust or change the drive device, improving the adaptability of grinding wheel 217. While reducing the time for reversing adjustment, the grinding efficiency of the brake drum 11 is improved. During the rotation of the grinding wheel 217, outside air enters the interior of the sliding cover 31 to form an airflow. The airflow moves with the grinding wheel 217 and dissipates heat from it. When the airflow touches the baffle 317, it forms a vortex between the baffle 317 and the grinding wheel 217, cleaning the loose grinding debris on the side wall of the grinding wheel 217. The vortex formed by the contact of the cleaning plate 315 and the airflow cleans the grinding wheel 217, improving the grinding effect of the grinding wheel 217 and preventing grinding debris from clogging the pores on the side wall of the grinding wheel 217 and affecting the grinding effect. At the same time, the airflow dissipates heat from the grinding wheel 217, increasing its lifespan.

[0046] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
