Description

Technical Field

[0001] This invention relates to the field of metal sheet processing technology, specifically to a gantry-type high-efficiency intelligent swing water grinding machine for metal sheet surface treatment. Background Technology

[0002] After metal sheets are processed and formed, their surfaces usually have residual oxide scale or minor unevenness, requiring grinding equipment to grind the surface of the metal sheets to meet the requirements of subsequent processing.

[0003] Existing metal plate grinding equipment has some structural shortcomings in actual operation. The surface of the processed metal plate often has a certain degree of undulation and deformation. However, the grinding heads of traditional grinding equipment mostly use a rigid feed structure, and the downward pressing distance of the grinding head is fixed. It cannot adaptively adjust according to the undulation of the metal plate surface, which easily leads to over-grinding of the raised parts of the metal plate and under-grinding of the concave parts. During the grinding operation, the metal plate will be subjected to a large cutting friction force. Conventional equipment usually only sets fixed clamps around the worktable. When a large area of ​​metal plate is subjected to horizontal grinding resistance, the main body of the plate is prone to displacement or edge warping, making it difficult to maintain a stable processing state. The grinding process generates a lot of heat and metal chips. If the rinsing and cooling are not adequate, the chips accumulated in some areas will cause secondary scratches on the surface of the metal plate as the grinding disc rotates. In addition, the grinding disc at the bottom of the grinding equipment will develop thickness wear after long-term operation. Traditional equipment lacks an automatic detection structure for the wear of the grinding disc. Operators need to stop the machine for manual inspection and manually adjust the spindle height, which reduces the continuity of the grinding operation and makes it difficult to ensure the consistency of the processed thickness. Therefore, this invention proposes a gantry-type high-efficiency intelligent swing water grinding machine for metal plate surface treatment to overcome the shortcomings of the prior art. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a gantry-type high-efficiency intelligent swing water grinding machine for metal plate surface treatment. It solves the problems of existing metal plate grinding equipment where the rigid feed of the grinding head cannot adapt to the uneven deformation of the metal plate surface, resulting in local over-grinding; when grinding large-area metal plates, the metal plate is prone to positional displacement or edge lifting under stress; and there is a lack of an automatic detection structure for grinding disc wear and consumption.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A gantry-type high-efficiency intelligent swing water grinding machine for metal plate surface treatment includes: a grinding platform, on both sides of the grinding platform parallel to each other along the length direction of the platform, a moving bridge gantry frame slidably connected to the top of the moving bridge gantry track, a moving bridge drive mechanism connected to both ends of the moving bridge gantry frame and the moving bridge gantry track, a swing beam mechanism provided on the surface of the top beam of the moving bridge gantry frame, and a swing drive mechanism provided between the moving bridge gantry frame and the swing beam mechanism; A grinding disc lifting pneumatic mechanism is provided above the swing beam mechanism, and a grinding plate drive spindle component is provided directly below the grinding disc lifting pneumatic mechanism. The bottom output end of the grinding disc lifting pneumatic mechanism is fixedly connected to the top of the grinding plate drive spindle component, and a metal grinding disc is connected to the bottom end of the grinding plate drive spindle component.

[0006] Preferably, a motor is fixedly connected to one side of the top of the grinding plate drive spindle assembly, and the power output end of the motor is connected to the spindle drive inside the grinding plate drive spindle assembly. This arrangement can provide a stable power input for the high-speed rotation of the metal grinding disc.

[0007] Preferably, the moving bridge drive mechanism includes a first reducer fixedly connected to the bottom of the moving bridge gantry frame, a first gear fixedly connected to the output end of the first reducer, and a first rack fixedly connected along the length direction to the side wall of the moving bridge gantry track. The first gear and the first rack on the side wall of the moving bridge gantry track mesh with each other. Through the transmission cooperation of the gear and rack, the power conversion and stable drive of the moving bridge gantry frame to translate along the longitudinal track are realized.

[0008] Preferably, a first guide rail slider is fixedly connected to the bottom of the moving bridge gantry frame outside the first reducer, and a longitudinal linear guide rail is fixedly connected to the top of the moving bridge gantry track. The first guide rail slider is sleeved on the outside of the longitudinal linear guide rail and slidably connected to the longitudinal linear guide rail. The cooperation between the linear guide rail and the slider reduces motion friction and ensures the stability of the longitudinal sliding of the entire machine structure and the accuracy of linear guidance.

[0009] Preferably, the swing drive mechanism includes a second reducer fixedly connected to the front surface of the swing beam mechanism. The output shaft of the second reducer on the front surface of the swing beam mechanism passes through the swing beam mechanism and is fixedly connected to a second gear. A second rack is fixedly connected to the side wall of the moving bridge gantry in the horizontal direction. The second gear and the second rack are meshed with each other. This structure utilizes the alternating forward and reverse rotation of the gears to drive the beam mechanism to complete the lateral reciprocating swing motion.

[0010] Preferably, the swing beam mechanism has at least one second guide rail slider fixedly connected to the back of the moving bridge gantry, and a transverse linear guide rail is fixedly connected to the side wall of the moving bridge gantry. The second guide rail slider is sleeved on the outside of the transverse linear guide rail and slidably connected to the transverse linear guide rail. This arrangement effectively improves the load-bearing capacity and structural stability of the swing beam mechanism during transverse reciprocating motion.

[0011] Preferably, pressure rollers are provided on both sides inside the moving bridge gantry, and each pressure roller is connected to a clamping cylinder at both ends. The top of the clamping cylinder is fixedly connected to the bottom wall of the moving bridge gantry, and the bottom of the pressure roller is in contact with the top surface of the grinding platform. The pressure rollers press the metal plate under the thrust of the cylinders, which can prevent the plate from shifting or the edges from lifting during the grinding process.

[0012] Preferably, a safety door is provided on the outer side of the grinding platform, which encloses the moving bridge gantry track and the moving bridge gantry frame within the internal area. An intelligent control system is provided at the outer end of the grinding platform, and the intelligent control system is electrically connected to the moving bridge drive mechanism, the swing drive mechanism, the grinding disc lifting pneumatic mechanism, and the clamping cylinder. The safety door effectively blocks the splashes generated during grinding, while the intelligent control system realizes automated collaborative control of the multi-axis mechanisms.

[0013] Preferably, the bottom of the swing beam mechanism is equipped with a water spray nozzle, the water outlet of which faces the gap between the bottom surface of the metal grinding disc and the top surface of the grinding platform. The water inlet of the spray nozzle is connected to an external water pump via a water pipe, and the external water pump is electrically connected to the intelligent control system. This water supply structure can spray the contact area during grinding, serving to cool the surface and rinse away surface debris.

[0014] Preferably, a displacement sensor is fixedly connected to the side wall of the grinding disc lifting pneumatic mechanism. The detection end of the displacement sensor faces the outer wall of the grinding disc drive spindle component. A metal sensing block corresponding to the detection end of the displacement sensor is fixedly connected to the outer wall of the grinding disc drive spindle component. The displacement sensor is electrically connected to the intelligent control system. The displacement sensor obtains the descent depth of the spindle by monitoring the position change of the sensing block, providing data feedback for the system to determine the wear condition of the grinding disc consumables.

[0015] This invention provides a gantry-type high-efficiency intelligent oscillating water grinding machine for metal plate surface treatment. It has the following beneficial effects: 1. This invention controls the moving bridge gantry to move longitudinally along the moving bridge gantry track, and in conjunction with the swing drive mechanism to drive the swing beam mechanism to move laterally back and forth, so that the metal grinding disc forms a cross-shaped running trajectory on the surface of the metal plate, which meets the processing needs of large-area metal plates. At the same time, the grinding disc lifting pneumatic mechanism provides flexible pneumatic downward pressure for the metal grinding disc, which can adapt to the undulating deformation state of the metal plate surface and reduce the phenomenon of local over-grinding.

[0016] 2. The present invention provides pressure rollers and pressing cylinders on both sides inside the moving bridge gantry. The pressing cylinders push the pressure rollers downward and press them against the surface of the metal plate. When the moving bridge gantry moves longitudinally, it drives the pressure rollers to roll on the surface of the metal plate. The pressure rollers press the metal plate against the grinding plate platform by the thrust applied by the pressing cylinders, preventing the metal plate from shifting position or lifting edges when it is subjected to grinding force, and maintaining the flatness of the metal plate during the processing.

[0017] 3. This invention provides a displacement sensor on the side wall of the grinding disc lifting pneumatic mechanism and a metal sensing block installed on the outer wall of the grinding disc drive spindle component. When the metal grinding disc experiences thickness wear, the grinding disc lifting pneumatic mechanism pushes the grinding disc drive spindle component downward to fill the wear gap. The displacement sensor continuously detects the relative position of the metal sensing block. By acquiring the displacement change of the metal sensing block, the wear and consumption of the metal grinding disc can be reflected, providing data reference for operators to replace the metal grinding disc later.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-4 This invention provides a gantry-type high-efficiency intelligent swing water grinding machine for metal plate surface treatment, comprising: a grinding platform 1, with moving bridge gantry rails 2 arranged parallel to each other along the length direction on both sides of the grinding platform 1, a moving bridge gantry frame 3 slidably connected to the top of the moving bridge gantry rails 2, a moving bridge drive mechanism 4 connected between both ends of the moving bridge gantry frame 3 and the moving bridge gantry rails 2, a swing beam mechanism 5 provided on the top beam surface of the moving bridge gantry frame 3, and a swing drive mechanism 6 provided between the moving bridge gantry frame 3 and the swing beam mechanism 5; A grinding disc lifting pneumatic mechanism 8 is provided above the swing beam mechanism 5, and a grinding plate drive spindle component 7 is provided directly below the grinding disc lifting pneumatic mechanism 8. The bottom output end of the grinding disc lifting pneumatic mechanism 8 is fixedly connected to the top of the grinding plate drive spindle component 7, and a metal grinding disc 9 is connected to the bottom end of the grinding plate drive spindle component 7.

[0022] Specifically, the grinding plate platform 1 mainly provides a supporting plane for placing the metal plate to be processed. The moving bridge gantry 3 spans above the grinding plate platform 1. Power is input from the moving bridge drive mechanisms 4 on both sides, enabling the moving bridge gantry 3 to move longitudinally along the moving bridge gantry track 2, meeting the processing space requirements of large-area metal plates. When the swing drive mechanism 6 operates, it outputs driving force, driving the swing beam mechanism 5 to slide laterally back and forth along the top beam surface of the moving bridge gantry 3. When the grinding disc lifting pneumatic mechanism 8 operates, it generates a downward thrust, pushing the grinding plate drive spindle component 7 below, together with the metal grinding disc 9 at the bottom, to produce a vertical downward displacement. During this movement... The grinding plate drive spindle component 7 can be tracked by a vertical guide component slidably connected to the swing beam mechanism 5 to resist the horizontal lateral force generated during grinding operations, thereby pressing the metal grinding disc 9 against the metal plate surface on the grinding plate platform 1. The longitudinal movement of the moving bridge gantry 3, the lateral reciprocating movement of the swing beam mechanism 5, and the vertical pressing action of the grinding disc lifting pneumatic mechanism 8 are coordinated synchronously, so that the metal grinding disc 9 forms a cross-shaped running trajectory on the metal plate surface. The downward pushing action provided by the grinding disc lifting pneumatic mechanism 8 can provide flexible pneumatic downward pressure, adapt to the undulating deformation state of the metal plate surface, and reduce local over-grinding.

[0023] Please see Figure 4 A motor 13 is fixedly connected to one side of the top of the grinding plate drive spindle assembly 7, and the power output end of the motor 13 is connected to the spindle drive inside the grinding plate drive spindle assembly 7.

[0024] Specifically, when the motor 13 is powered on, it outputs rotational power. The rotational power is transmitted to the spindle inside the grinding plate drive spindle assembly 7 through the pulley assembly or gear set, driving the spindle to rotate, thereby causing the metal grinding disc 9 connected to the bottom of the spindle to rotate synchronously. The motor 13 provides the power source for the grinding action of the metal grinding disc 9, which helps to maintain the stability of the grinding operation on the surface of the metal plate.

[0025] Please see Figure 3 The moving bridge drive mechanism 4 includes a first reducer 15 fixedly connected to the bottom of the moving bridge gantry 3. A first gear 16 is fixedly connected to the output end of the first reducer 15. A first rack 17 is fixedly connected to the side wall of the moving bridge gantry track 2 along the length direction. The first gear 16 and the first rack 17 on the side wall of the moving bridge gantry track 2 are meshed with each other.

[0026] Specifically, the first reducer 15 drives the first gear 16 to rotate, and the first rack 17 is fixed to the side wall of the moving bridge gantry track 2 and remains stationary. The rotating first gear 16 and the first rack 17 continuously mesh, generating a linear thrust, which pushes the moving bridge gantry 3 to slide along the moving bridge gantry track 2. The first reducer 15 reduces the speed and increases the torque. Combined with the meshing structure of the first gear 16 and the first rack 17, it helps to overcome the resistance when the moving bridge gantry 3 moves, and provides a relatively stable driving force for the longitudinal movement of the moving bridge gantry 3.

[0027] Please see Figure 3 The bottom of the moving bridge gantry 3 is fixedly connected to the first guide rail slider 14 outside the first reducer 15. The top of the moving bridge gantry track 2 is fixedly connected to the longitudinal linear guide rail. The first guide rail slider 14 is sleeved on the outside of the longitudinal linear guide rail and slidably connected to the longitudinal linear guide rail.

[0028] Specifically, when the moving bridge gantry 3 moves, the first guide rail slider 14 slides along the surface of the longitudinal linear guide rail. The cooperation structure between the first guide rail slider 14 and the longitudinal linear guide rail bears the weight of the moving bridge gantry 3 when it moves, and at the same time restricts the direction of movement of the moving bridge gantry 3. The cooperation between the first guide rail slider 14 and the longitudinal linear guide rail helps to reduce the frictional resistance during the movement of the moving bridge gantry 3 and maintain the straightness of the moving bridge gantry 3 during longitudinal movement.

[0029] Please see Figure 5 and Figure 6 The swing drive mechanism 6 includes a second reducer 19 fixedly connected to the front surface of the swing beam mechanism 5. The output shaft of the second reducer 19 on the front surface of the swing beam mechanism 5 passes through the swing beam mechanism 5 and is fixedly connected to a second gear 20. A second rack 21 is fixedly connected to the side wall of the moving bridge gantry 3 in the horizontal direction. The second gear 20 and the second rack 21 are meshed with each other.

[0030] Specifically, the second reducer 19 outputs rotational power, which drives the second gear 20 connected to the output shaft of the second reducer 19 to rotate. The rotating second gear 20 continuously meshes with the second rack 21 fixed to the side wall of the moving bridge gantry 3, generating a thrust in the horizontal direction. Through the alternating forward and reverse rotation of the output shaft of the second reducer 19, the swing beam mechanism 5 is driven to slide laterally back and forth along the top beam surface of the moving bridge gantry 3. The structural arrangement of the second gear 20 connected to the output shaft of the second reducer 19 through the swing beam mechanism 5 helps to improve the structural compactness of the swing beam mechanism 5. The meshing transmission mode of the second gear 20 and the second rack 21 helps to maintain the stability of the swing beam mechanism 5 during the lateral movement.

[0031] Please see Figure 5 and Figure 6The swing beam mechanism 5 is fixedly connected to at least one second guide rail slider 18 near the back of the moving bridge gantry 3. The side wall of the moving bridge gantry 3 is fixedly connected to a transverse linear guide rail. The second guide rail slider 18 is sleeved on the outside of the transverse linear guide rail and slidably connected to the transverse linear guide rail.

[0032] Specifically, when the swing beam mechanism 5 moves laterally, the second guide rail slider 18, which is fixed on the back of the swing beam mechanism 5, slides along the surface of the transverse linear guide rail. The cooperation structure between the second guide rail slider 18 and the transverse linear guide rail provides trajectory guidance for the lateral movement of the swing beam mechanism 5, while bearing the weight of the swing beam mechanism 5. The sliding connection between the second guide rail slider 18 and the transverse linear guide rail helps to reduce frictional resistance and maintain the stability of the swing beam mechanism 5 during lateral movement.

[0033] Please see Figure 2 The moving bridge gantry 3 has pressure rollers 10 on both sides inside. Both ends of the pressure rollers 10 are connected to pressing cylinders. The top of the pressing cylinders is fixedly connected to the bottom wall of the moving bridge gantry 3, and the bottom of the pressure rollers 10 is in contact with the top surface of the grinding plate platform 1.

[0034] Specifically, after the metal plate to be processed is placed on the grinding platform 1, the clamping cylinder generates a downward thrust, which pushes the pressure roller 10 connected below the clamping cylinder downward, so that the pressure roller 10 presses against the surface of the metal plate. When the moving bridge gantry 3 moves longitudinally along the moving bridge gantry track 2, the pressure roller 10 moves synchronously with the moving bridge gantry 3 and rolls on the surface of the metal plate. The pressure roller 10 presses the metal plate firmly on the grinding platform 1 by the thrust applied by the clamping cylinder, which can reduce the possibility of positional displacement or edge lifting of the metal plate when it is subjected to grinding force, maintain the flatness of the metal plate during processing, and provide a stable foundation for the grinding operation of the metal grinding disc 9.

[0035] Please see Figure 2 A safety protection door 12 is provided on the outside of the grinding plate platform 1. The safety protection door 12 covers the moving bridge gantry rail 2 and the moving bridge gantry frame 3 in the internal area. An intelligent control system 11 is provided at the outer end of the grinding plate platform 1. The intelligent control system 11 is electrically connected to the moving bridge drive mechanism 4, the swing drive mechanism 6, the grinding plate lifting pneumatic mechanism 8, and the clamping cylinder.

[0036] Specifically, when the equipment is performing grinding operations, the safety door 12 isolates the internal processing area. The safety door 12 prevents metal chips and water splashes generated during the grinding process of the metal grinding disc 9 from splashing outward, reducing the impact of splashes on the surrounding environment. The operator inputs operation commands through the intelligent control system 11, and the intelligent control system 11 sends out electrical signals to control the moving bridge drive mechanism 4, the swing drive mechanism 6, the grinding disc lifting pneumatic mechanism 8, the motor 13, and the clamping cylinder to perform synchronous actions, completing the coordinated control of the equipment's longitudinal, lateral, and vertical feeds.

[0037] Please see Figures 1-2 The bottom of the swing beam mechanism 5 is equipped with a water nozzle. The water outlet of the water nozzle faces the gap between the bottom surface of the metal grinding disc 9 and the top surface of the grinding plate platform 1. The water inlet of the water nozzle is connected to an external water pump through a water pipe. The external water pump is electrically connected to the intelligent control system 11.

[0038] Specifically, during the grinding process, an external water pump operates to pump water into the water pipe. The water flows through the water pipe into the spray nozzle and then sprays out from the outlet of the nozzle. The sprayed water enters the gap between the bottom surface of the metal grinding disc 9 and the top surface of the grinding platform 1, covering the surface of the grinding area of ​​the metal plate. The water cools down the grinding contact area and washes away the metal debris accumulated on the surface of the metal plate, reducing the possibility of secondary scratches on the surface of the metal plate by metal debris, thus providing conditions for wet grinding of the metal grinding disc 9.

[0039] Please see Figures 1-2 A displacement sensor is fixedly connected to the side wall of the grinding disc lifting pneumatic mechanism 8. The detection end of the displacement sensor faces the outer wall of the grinding disc drive spindle component 7. A metal sensing block corresponding to the detection end of the displacement sensor is fixedly connected to the outer wall of the grinding disc drive spindle component 7. The displacement sensor is electrically connected to the intelligent control system 11.

[0040] Specifically, when the metal grinding disc 9 experiences thickness wear during long-term grinding, the grinding disc lifting pneumatic mechanism 8 pushes the grinding plate drive spindle component 7 downwards a greater distance, ensuring that the metal grinding disc 9 remains in contact with the metal plate surface. As the grinding plate drive spindle component 7 moves downwards, it causes the metal sensing block fixedly connected to the outer wall to undergo synchronous displacement changes. The displacement sensor fixed to the side wall of the grinding disc lifting pneumatic mechanism 8 continuously detects the relative position of the metal sensing block. By obtaining the displacement change of the metal sensing block through the displacement sensor, it helps to obtain the wear and tear of the metal grinding disc 9, providing data reference for subsequent replacement of the metal grinding disc 9.

[0041] Working principle: First, the metal plate to be processed is placed on the grinding platform 1. Then, the pressing cylinders at both ends of the pressure roller 10 generate a downward thrust, pushing the pressure roller 10 downward and pressing it against the surface of the metal plate, pressing the metal plate firmly onto the grinding platform 1. The safety door 12 closes to isolate the internal processing area. The operator inputs operation commands through the intelligent control system 11 and sends an electrical signal to start the equipment.

[0042] After the grinding operation is started, the external water pump operates to pump water into the water pipe. The water flows into the nozzle along the water pipe and sprays out from the outlet, continuously spraying to the gap between the metal grinding disc 9 and the metal plate, covering the surface of the grinding area. At the same time, the motor 13 is powered on and outputs rotational power, which drives the main shaft inside the grinding disc drive spindle component 7 to rotate through the pulley assembly or gear set, causing the metal grinding disc 9 at the bottom to rotate synchronously. Then, the grinding disc lifting pneumatic mechanism 8 is activated to generate downward thrust, pushing the grinding disc drive spindle component 7 and the metal grinding disc 9 to move vertically downward. The grinding disc drive spindle component 7 is tracked by the vertical guide component that is slidably connected to the swing beam mechanism 5 until the metal grinding disc 9 is pressed against the surface of the metal plate.

[0043] While the metal grinding disc 9 is rotating and pushing downwards, the moving bridge drive mechanism 4 and the swing drive mechanism 6 operate synchronously. The first reducer 15 drives the first gear 16 to rotate. The first gear 16 continuously meshes with the stationary first rack 17 to generate a linear thrust, which pushes the moving bridge gantry 3 and the pressure roller 10 to slide longitudinally along the longitudinal linear guide rail. The pressure roller 10 then rolls on the surface of the metal plate. At the same time, the second reducer 19 alternately rotates in the forward and reverse directions, driving the second gear 20 and the second rack 21 to continuously mesh to generate a horizontal thrust, which drives the swing beam mechanism 5 to slide laterally along the transverse linear guide rail. The longitudinal movement of the moving bridge gantry 3, the transverse reciprocating movement of the swing beam mechanism 5, the vertical pressing action of the grinding disc lifting pneumatic mechanism 8, and the rotation of the metal grinding disc 9 are synchronized to control the metal grinding disc 9 to perform grinding action on the surface of the metal plate in a cross-patterned running trajectory.

[0044] During the continuous grinding operation, when the metal grinding disc 9 experiences thickness wear due to friction, the grinding disc lifting pneumatic mechanism 8 continues to push the grinding plate drive spindle component 7 downward by a corresponding distance, so that the metal grinding disc 9 remains in contact with the surface of the metal plate. When the grinding plate drive spindle component 7 moves downward, it causes the external metal sensing block to undergo synchronous displacement change. The displacement sensor continuously detects the relative position of the metal sensing block, obtains the displacement change data of the metal sensing block, and transmits it to the intelligent control system 11.
