Description

Technical Field

[0001] The invention relates to the technical field of mold grinding, in particular to a multi-faceted and multi-hole grinding station. Background Art

[0002] The gas circuit board is usually used in systems that require precise control of gas flow, such as pneumatic control systems of automated robotic arms, pneumatic fixtures, pneumatic valves, pneumatic actuators, etc. In these systems, the function of the gas circuit board is to distribute, connect and control the flow of gas to different actuators to ensure efficient and accurate operation of the system. The gas circuit board is usually a square six-sided structure, and there are multiple air holes on multiple faces of the gas circuit board. There are both round holes and square holes in the multiple air holes. After these air holes are injection molded, burrs will exist in the holes, which need to be polished and removed.

[0003] Since traditional grinding equipment is only suitable for single-sided single-hole grinding of the air manifold, it is impossible to grind multiple air holes of different shapes on different surfaces at the same time. To meet the grinding needs of the above-mentioned air manifold, the existing grinding method is usually: manually holding a grinding drill to grind multiple air holes on different surfaces of the air manifold one by one. This method is time-consuming and labor-intensive, with low operating efficiency, and it is difficult to achieve automated grinding of multiple inner holes on multiple grinding surfaces of the air manifold.

[0004] Therefore, designing a grinding device that can adapt to the grinding of multiple inner holes on multiple grinding surfaces of the gas path plate is a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0005] The purpose of the present invention is to overcome at least one defect in the prior art and provide a multi-surface multi-hole grinding station capable of automatically grinding multiple inner holes on multiple grinding surfaces of a gas path plate.

[0006] To solve the above problems, the present invention provides a multi-faceted and multi-hole grinding station, comprising a workbench and a clamping mechanism, a first grinding mechanism, and a second grinding mechanism arranged on the top of the workbench, the first grinding mechanism being located on at least one side of the front and rear sides of the clamping mechanism, the first grinding mechanism comprising a first grinding brush and a rotating motor for driving the first grinding brush to rotate, a first moving mechanism for driving the rotating motor to move forward and backward and left and right is provided between the first grinding mechanism and the workbench, the second grinding mechanism is located on at least one side of the left and right sides of the clamping mechanism, the second grinding mechanism comprising a first multi-axis drive motor and a plurality of second grinding brushes fixedly arranged on a plurality of output ends of the first multi-axis drive motor in a one-to-one correspondence, the first multi-axis drive motor being used to drive the plurality of second grinding brushes to rotate, and a second moving mechanism for driving the first multi-axis drive motor to move left and right is provided between the second grinding mechanism and the workbench.

[0007] Compared with the prior art, the benefit of the present invention lies in that: the present invention provides a more efficient and higher degree of automation multi-faceted and multi-hole grinding station, which automatically grinds the front and back faces and left and right faces of the air circuit plate in different ways through a first grinding mechanism and a second grinding mechanism. Specifically, the first grinding mechanism grinds the multiple holes on the front and back faces of the air circuit plate one by one by moving forward and backward and left and right, while the second grinding mechanism can simultaneously grind the multiple holes on the left and right faces of the air circuit plate only by moving left and right. This unique structural design effectively improves the grinding efficiency of the air circuit plate, reduces the labor intensity of manual operation, reduces production costs, and is beneficial to improving the surface quality of the air circuit plate and improving product performance.

[0008] Specifically, the first moving mechanism includes a first left and right feed linear module and a front and rear feed linear module. The first left and right feed linear module is used to drive the front and rear feed linear module to move left and right. The front and rear feed linear module is used to drive the rotating motor to move forward and backward. The first left and right feed linear modules are fixedly arranged on the top of the workbench in a left and right distribution. The front and rear feed linear modules are fixedly arranged at the output end of the first left and right feed linear module in a front and rear distribution through a mounting seat. The rotating motor is fixedly arranged at the output end of the front and rear feed linear module through a fixing seat, and the output end of the rotating motor is arranged in the direction of the clamping mechanism. The second moving mechanism includes a second left and right feed linear module and a connecting seat fixedly arranged at the output end of the second left and right feed linear module. The first multi-axis drive motor is fixedly arranged on the connecting seat, and the output end of the first multi-axis drive motor is arranged in the direction of the clamping mechanism. After applying this structure, when in use, through the coordinated driving of the first left and right feed linear module and the front and rear feed linear module, the rotating motor can freely move in two dimensions, left and right and front and back, on the front and rear sides of the clamping mechanism, so that the first grinding brush arranged at the output end of the rotating motor is used to grind the multiple holes on the front and back sides of the air circuit plate one by one. At the same time, the second left and right feed linear module drives the first multi-axis drive motor to move left and right on the left rear side of the clamping mechanism, and with the help of multiple second grinding brushes arranged at the output end of the first multi-axis drive motor, the multiple holes on the left and right surfaces of the air circuit plate can be polished simultaneously. This grinding method greatly improves the grinding efficiency, reduces the operating steps, reduces labor costs, and improves the surface quality and product performance of the air circuit plate.

[0009] As an improvement, a lifting mechanism is provided between the rotating motor and the fixed seat, and the lifting mechanism includes a vertical plate fixed vertically on the fixed seat, a first slider rail assembly and a first lifting cylinder arranged on the vertical plate, the rotating motor is arranged on the first slider rail assembly, and the first lifting cylinder is used to drive the rotating motor to move up and down. This improvement enables the rotating motor to move freely in three dimensions: left and right, front and back, and up and down. The first grinding brush arranged at the output end of the rotating motor is used to grind multiple holes at different heights on the front and rear surfaces of the gas circuit board one by one, thereby effectively improving the grinding efficiency, improving the surface quality of the gas circuit board, and increasing the range and height of the holes that can be grinded, making the grinding station more widely used.

[0010] Specifically, the second grinding brush includes a rotating brush head, a long connecting rod fixedly connected between the rotating brush head and the output end of the first multi-axis drive motor, and a brush head seat for positioning the rotating brush head. The brush head seat is fixedly set on the workbench through a vertical frame, and the brush head seat has a socket for inserting one end of the rotating brush head. In this structure, the setting of the long connecting rod facilitates the grinding of the deeper round holes on the left and right sides of the gas circuit board. The setting of the brush head seat and the socket on the brush head seat provides positioning for the position alignment of the rotating brush head with the multiple round holes on the left and right sides of the gas circuit board. At the same time, under the coordinated action of the vertical frame, the brush head seat can provide effective support for the long connecting rod, prevent the rotating brush head from shaking, keep the rotating brush head stable, ensure grinding accuracy, and prevent the gas circuit board body from being worn out. This improvement effectively improves the grinding accuracy of the grinding station, ensures the grinding quality, and prevents the gas circuit board from being damaged during the grinding process, further improving the surface quality and product performance of the gas circuit board.

[0011] Specifically, the clamping mechanism includes a base positioned on the top of the workbench and a front and rear clamping assembly and a left and right clamping assembly arranged on the base. The front and rear clamping assembly includes a pair of finger cylinders arranged side by side left and right and a clamping block group arranged at the clamping end of the finger cylinder for front and rear opening and closing. The finger cylinder is positioned on the base through a fixed block. The clamping block group includes a pair of clamping blocks arranged side by side front and back. The left and right clamping assemblies include a left clamping block and a right clamping block arranged on the outside of the clamping ends of a pair of finger cylinders in a left and right arrangement, and a telescopic cylinder for driving the left clamping block to move rightward close to the right clamping block. The telescopic cylinder is fixedly arranged on the fixed block located on the left side through a left support. The left clamping block is fixedly arranged on the output end of the telescopic cylinder, and the right clamping block is fixedly arranged on the fixed block located on the right side through a right support. After applying this structure, under the dual clamping action of the front and rear clamping assemblies and the left and right clamping assemblies, the air circuit plate can be fixed more firmly, and the telescopic cylinder can drive the left clamping block to approach the right clamping block to achieve fine-tuning of the air circuit plate, ensuring that the air circuit plate can be accurately aligned with the grinding brush head during the grinding process. At the same time, the finger cylinder and the telescopic cylinder are positioned on the base through the fixed block, which can ensure that the clamping mechanism maintains a stable position during operation. This improved clamping mechanism can effectively improve the fixing accuracy of the air circuit plate and prevent the air circuit plate from being displaced during the grinding process, thereby improving the grinding accuracy and efficiency, reducing the risk of damage to the air circuit plate, and ultimately improving the surface quality and product performance of the air circuit plate.

[0012] As an improvement, the top of the base is provided with a plurality of mounting hole groups arranged at intervals on the left and right and a support block for supporting and setting a fixed block. The mounting hole group includes a pair of mounting holes arranged side by side in front and back. The fixed block is fixedly connected to the pair of mounting holes in the mounting hole group by bolts. The support blocks are fixedly arranged on the top of the base in the left and right distributions and are located between the pair of mounting holes in the mounting hole group. The bottom of the fixed block is provided with a card slot for clamping on the support block in the front and back. This improvement enables the clamping mechanism to adapt to the clamping and fixing needs of air circuit boards of different lengths. By selecting different limit mounting holes to install the fixed block, the position of a pair of finger cylinders and the spacing between the left clamp block and the right clamp block can be adjusted to adapt to the clamping needs of air circuit boards of different lengths. The clamping fit of the support block and the card slot can achieve a more secure connection between the fixed block and the base, thereby improving the versatility and reliability of the clamping mechanism.

[0013] As an improvement, a square hole grinding mechanism and a forward and backward moving mechanism are provided on the top of the workbench. The square hole grinding mechanism is arranged side by side on one side of the second grinding mechanism. The forward and backward moving mechanism is used to drive the base to move and switch positions between the second grinding mechanism and the square hole grinding mechanism. The square hole grinding mechanism includes a support frame fixedly arranged on the top of the workbench, a square grinding brush slidably arranged on the support frame, and a first push cylinder arranged on the support frame for driving the square grinding brush to move left and right. The output end of the first push cylinder is arranged in a direction away from the clamping mechanism. The forward and backward moving mechanism includes a support rail group and a rodless cylinder extending forward and backward on the top of the workbench. The base is slidably arranged on the support rail group and fixedly connected to the output end of the rodless cylinder. This improvement can use the square hole grinding mechanism to grind the air path plate with square holes on the left and right sides, and the front-and-back moving mechanism can make the distance between the second grinding mechanism and the square hole grinding mechanism not limited by the distance between the round holes and the square holes on the left and right surfaces of the air path plate, thereby ensuring that the second grinding mechanism and the square hole grinding mechanism can be normally arranged on the workbench. The setting of the front-and-back moving mechanism solves the problem that the second grinding mechanism and the square hole grinding mechanism cannot be arranged side by side on the workbench due to the small distance between the round holes and the square holes on the left and right surfaces of the air path plate, thereby improving the applicability of the grinding equipment. In addition, in the square hole grinding mechanism, the structural design in which the output end of the first push cylinder is arranged in a direction away from the clamping mechanism can make the overall structure of the grinding station more compact and reduce the footprint.

[0014] As an improvement, the square grinding brush includes a square brush head and a connecting block fixedly connected between the square brush head and the output end of the first push cylinder. A guide groove is opened on the support frame and is provided with a pad block and a second push cylinder. The guide grooves are distributed on the left and right sides of the support frame and are used for positioning and inserting one end of the square brush head. The pad block is slidably set in the guide groove and supported at the bottom of the square brush head and the connecting block. The output end of the second push cylinder is set in a direction away from the clamping mechanism and is used to drive the pad block to move synchronously with the square brush head. This improvement improves the grinding accuracy and the compactness of the equipment structure by optimizing the design of the square grinding brush and the support frame. Specifically, the combination of the square brush head and the connecting block allows the brush head to enter the square hole of the air board more deeply, which can be adapted to the precise grinding of deeper square holes on the air board. The guide groove on the support frame provides precise guidance for the positioning of the brush head, ensuring that the brush head always maintains the correct direction to prevent deviation during the grinding process. The setting of the pad effectively prevents the brush head from sagging on one side of the connecting block, avoiding the reduction in grinding accuracy and damage to the air board due to the sagging of the brush head. In addition, the output end of the second push cylinder is set in a direction away from the clamping mechanism, which makes the overall structure of the grinding station more compact and saves space.

[0015] As an improvement, a top grinding mechanism is provided on the mounting seat, which includes a stand vertically fixed on the mounting seat, a second multi-axis drive motor and a lifting mechanism arranged on the stand, and at least one rotating grinding brush fixedly arranged at the output end of the second multi-axis drive motor in a one-to-one correspondence. The lifting mechanism includes a second slider rail assembly and a second lifting cylinder arranged on the stand, the output end of the second multi-axis drive motor is downwardly arranged on the second slider rail assembly, and the second lifting cylinder is used to drive the second multi-axis drive motor to move up and down. This improvement expands the function of the grinding station by adding a top grinding mechanism, and is capable of handling the grinding of circular holes on the upper and lower surfaces of the air circuit board. In this structure, the top grinding mechanism and the first grinding mechanism share a left and right feed linear module and a mounting seat, which simplifies the structure, reduces costs, and makes the overall structure more compact. Among them, the structural design of arranging the top grinding mechanism and the first grinding mechanism on the same side of the clamping mechanism leaves more space for other components, which is conducive to optimizing the overall structural layout. In addition, when there are multiple rows of circular holes arranged side by side on the upper and lower sides of the air circuit board, multiple rows of circular holes can be effectively polished synchronously by arranging multiple rotating grinding brushes at the output end of the second multi-axis drive motor.

[0016] As an improvement, a dust removal duct is fixed on the vertical plate through a bracket, one end of the bracket is fixedly connected to the vertical plate, the other end of the bracket extends upward to the clamping mechanism, and the air outlet of the dust removal duct is downwardly arranged at the other end of the bracket. After applying this structure, the dust removal duct can blow away foreign matter such as grinding debris attached to the contact surface of the air path plate and the clamping mechanism, ensuring that the clamping mechanism firmly clamps the air path plate and guarantees the grinding quality. In addition, the dust removal duct and the first grinding mechanism share a set of left and right movement control systems, which simplifies the structure of the grinding station, saves manufacturing costs, and improves the economy of the equipment.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2As shown, in the present invention, the multi-faceted and multi-hole grinding station includes a workbench 1 and a clamping mechanism 2, a first grinding mechanism 3 and a second grinding mechanism 4 arranged on the top of the workbench 1, the first grinding mechanism 3 is located on at least one side of the front and rear sides of the clamping mechanism 2, the first grinding mechanism 3 includes a first grinding brush 31 and a rotating motor 32 for driving the first grinding brush 31 to rotate, a first moving mechanism 5 for driving the rotating motor 32 to move forward and backward and left and right is provided between the first grinding mechanism 3 and the workbench 1, the second grinding mechanism 4 is located on at least one side of the left and right sides of the clamping mechanism 2, the second grinding mechanism 4 includes a first multi-axis drive motor 41 and a plurality of second grinding brushes 42 fixedly arranged on a plurality of output ends of the first multi-axis drive motor 41 in a one-to-one correspondence, the first multi-axis drive motor 41 is used to drive the plurality of second grinding brushes 42 to rotate, and a second moving mechanism 6 for driving the first multi-axis drive motor 41 to move left and right is provided between the second grinding mechanism 4 and the workbench 1.

[0021] The present invention provides a more efficient and more automated multi-faceted and multi-hole grinding station, which automatically grinds the front and back faces and the left and right faces of the air circuit plate in different ways through a first grinding mechanism 3 and a second grinding mechanism 4. Specifically, the first grinding mechanism 3 grinds the multiple holes on the front and back faces of the air circuit plate one by one by moving forward and backward and left and right, while the second grinding mechanism 4 can simultaneously grind the multiple holes on the left and right faces of the air circuit plate only by moving left and right. This unique structural design effectively improves the grinding efficiency of the air circuit plate, reduces the labor intensity of manual operation, reduces production costs, and is beneficial to improving the surface quality of the air circuit plate and improving product performance.

[0022] like Figure 2 , Figure 6 and Figure 8As shown, the first moving mechanism 5 includes a first left and right feed linear module 51 and a front and rear feed linear module 52, the first left and right feed linear module 51 is used to drive the front and rear feed linear module 52 to move left and right, the front and rear feed linear module 52 is used to drive the rotary motor 32 to move forward and backward, the first left and right feed linear module 51 is fixedly arranged on the top of the workbench 1 in a left and right distribution, the front and rear feed linear module 52 is fixedly arranged on the output end of the first left and right feed linear module 51 in a front and rear distribution through a mounting seat 53, the rotary motor 32 is fixedly arranged at the output end of the front and rear feed linear module 52 through a fixing seat 54, and the output end of the rotary motor 32 is arranged toward the direction of the clamping mechanism 2, the second moving mechanism 6 includes a second left and right feed linear module 61 and a connecting seat 62 fixedly arranged at the output end of the second left and right feed linear module 61, the first multi-axis drive motor 41 is fixedly arranged on the connecting seat 62, and the output end of the first multi-axis drive motor 41 is arranged toward the direction of the clamping mechanism 2. After applying this structure, when in use, through the coordinated driving of the first left and right feed linear module 51 and the front and rear feed linear module 52, the rotating motor 32 can freely move in two dimensions, left and right and front and back, on the front and rear sides of the clamping mechanism 2, so that the first grinding brush 31 arranged at the output end of the rotating motor 32 is used to grind the multiple holes on the front and back sides of the air circuit plate one by one. At the same time, the second left and right feed linear module 61 drives the first multi-axis drive motor 41 to move left and right on the left rear side of the clamping mechanism 2, and with the help of multiple second grinding brushes 42 arranged at the output end of the first multi-axis drive motor 41, the multiple holes on the left and right surfaces of the air circuit plate can be polished simultaneously. This grinding method greatly improves the grinding efficiency, reduces the operating steps, reduces labor costs, and improves the surface quality and product performance of the air circuit plate.

[0023] like Figure 6 As shown, in order to further improve the grinding efficiency and precision, in the present invention, a lifting mechanism 55 is provided between the rotating motor 32 and the fixed seat 54, and the lifting mechanism 55 includes a vertical plate 551 vertically fixed on the fixed seat 54, and a first slider rail assembly 552 and a first lifting cylinder 553 arranged on the vertical plate 551, the rotating motor 32 is arranged on the first slider rail assembly 552, and the first lifting cylinder 553 is used to drive the rotating motor 32 to move up and down. Specifically, the first slider rail assembly 552 includes a pair of rails fixedly arranged on the vertical plate 551 and a slider slidably arranged on the pair of rails, the rotating motor 32 is fixedly arranged on the slider, and the output end of the first lifting cylinder 553 is fixedly connected to the slider. This improvement enables the rotating motor 32 to move freely in three dimensions: left and right, front and back, and up and down. The first grinding brush 31 arranged at the output end of the rotating motor 32 is used to grind multiple holes at different heights on the front and rear surfaces of the air circuit plate one by one, thereby effectively improving the grinding efficiency, improving the surface quality of the air circuit plate, and increasing the range and height of the grindable holes, making the grinding station more widely used.

[0024] like Figure 8 As shown, in order to improve the grinding accuracy of the deeper circular holes on the left and right sides of the air circuit plate, in the present invention, we have improved the second grinding brush 42. The second grinding brush 42 includes a rotating brush head 421, a long connecting rod 422 fixedly connected between the rotating brush head 421 and the output end of the first multi-axis drive motor 41, and a brush head seat 423 for positioning the rotating brush head 421. The brush head seat 423 is fixedly set on the workbench 1 through the vertical frame 10, and the brush head seat 423 has a socket 4230 for inserting one end of the rotating brush head 421. In this structure, the arrangement of the long connecting rod 422 facilitates the grinding of the deeper circular holes on the left and right sides of the air circuit plate. The arrangement of the brush head seat 423 and the socket 4230 on the brush head seat 423 provide positioning for the rotating brush head 421 to align with the multiple circular holes on the left and right sides of the air circuit plate. At the same time, with the coordinated action of the vertical frame 10, the brush head seat 423 can provide effective support for the long connecting rod 422, prevent the rotating brush head 421 from shaking, keep the rotating brush head 421 stable, ensure grinding accuracy, and prevent the air circuit plate body from being worn out. This improvement effectively improves the grinding accuracy of the grinding station, ensures the grinding quality, and prevents damage to the air circuit plate during the grinding process, further improving the surface quality and product performance of the air circuit plate.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, in order to further improve the clamping stability and accuracy of the gas circuit board, in the present invention, we have improved the clamping mechanism 2, which includes a base 21 positioned on the top of the workbench 1 and a front and rear clamping assembly 22 and a left and right clamping assembly 23 arranged on the base 21. The front and rear clamping assembly 22 includes a pair of finger cylinders 221 arranged side by side on the left and right sides and a clamping block group 222 arranged on the clamping end of the finger cylinder 221 for front and rear opening and closing. The finger cylinder 221 is positioned on the base 21 through a fixing block 24, and the clamping block group 22 2 comprises a pair of clamping blocks arranged side by side in front and back, the left and right clamping assemblies 23 comprise a left clamping block 231 and a right clamping block 232 which are arranged on the outside of the clamping ends of a pair of finger cylinders 221 in a left and right manner, and a telescopic cylinder 233 for driving the left clamping block 231 to move rightward close to the right clamping block 232, the telescopic cylinder 233 is fixedly arranged on the fixed block 24 located on the left side through a left support 241, the left clamping block 231 is fixedly arranged on the output end of the telescopic cylinder 233, and the right clamping block 232 is fixedly arranged on the fixed block 24 located on the right side through a right support 242. After applying this structure, under the dual clamping action of the front and rear clamping assemblies 22 and the left and right clamping assemblies 23, the air circuit plate can be fixed more firmly, and the telescopic cylinder 233 is used to drive the left clamping block 231 close to the right clamping block 232 to achieve fine-tuning of the air circuit plate, ensuring that the air circuit plate can be accurately aligned with the grinding brush head during the grinding process. At the same time, the finger cylinder 221 and the telescopic cylinder 233 are positioned on the base 21 through the fixed block 24, which can ensure that the clamping mechanism 2 maintains a stable position during operation. This improved clamping mechanism 2 can effectively improve the fixing accuracy of the air circuit plate and prevent the air circuit plate from being displaced during the grinding process, thereby improving the grinding accuracy and efficiency, reducing the risk of damage to the air circuit plate, and ultimately improving the surface quality and product performance of the air circuit plate.

[0026] like Figure 4As shown, in order to further enhance the versatility of the clamping mechanism 2 so that it can adapt to the clamping and fixing requirements of air circuit plates of different lengths, the top of the base 21 is provided with a plurality of mounting hole groups 210 spaced apart from each other on the left and right, and a support block 211 for supporting and setting the fixing block 24. The mounting hole group 210 includes a pair of mounting holes arranged side by side front and back, and the fixing block 24 is fixedly connected to the pair of mounting holes of the mounting hole group 210 by bolts. The support blocks 211 are fixedly arranged on the top of the base 21 on the left and right and are located between the pair of mounting holes of the mounting hole group 210. The bottom of the fixing block 24 is provided with a card slot 240 for clamping on the support block 211 front and back. This improvement enables the clamping mechanism 2 to adapt to the clamping and fixing needs of air circuit plates of different lengths. By selecting different limit mounting holes to install the fixing block 24, the positions of a pair of finger cylinders 221 and the spacing between the left clamping block 231 and the right clamping block 232 can be adjusted to adapt to the clamping needs of air circuit plates of different lengths. The snap-fitting fit between the support block 211 and the slot 240 can achieve a more secure connection between the fixing block 24 and the base 21, thereby improving the versatility and reliability of the clamping mechanism 2.

[0027] like Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, in order to be able to grind the air path plate with square holes on the left and right sides, in the present invention, a square hole grinding mechanism 7 and a front-and-back moving mechanism 8 are provided on the top of the workbench 1. The square hole grinding mechanism 7 is arranged side by side on one side of the second grinding mechanism 4. The front-and-back moving mechanism 8 is used to drive the base 21 to move and switch positions between the second grinding mechanism 4 and the square hole grinding mechanism 7. The square hole grinding mechanism 7 includes a support frame 71 fixedly arranged on the top of the workbench 1, a square grinding brush 72 slidably arranged on the support frame 71, and a first push cylinder 73 arranged on the support frame 71 for driving the square grinding brush 72 to move left and right. The output end of the first push cylinder 73 is arranged in a direction away from the clamping mechanism 2. The front-and-back moving mechanism 8 includes a support rail group 81 and a rodless cylinder 82 extending frontward and rearward on the top of the workbench 1. The base 21 is slidably arranged on the support rail group 81 and is fixedly connected to the output end of the rodless cylinder 82. Specifically, the support rail group 81 includes a pair of rails fixed side by side on the top of the workbench 1, the rodless cylinder 82 is arranged parallel to the pair of rails and located between the pair of rails, and the base 21 is slidably arranged on the pair of rails and fixedly connected to the output end of the rodless cylinder 82. This improvement can use the square hole grinding mechanism 7 to grind the air path plate with square holes on the left and right sides, and the front-back moving mechanism 8 can make the spacing between the second grinding mechanism 4 and the square hole grinding mechanism 7 not limited by the spacing between the round holes and the square holes on the left and right surfaces of the air path plate, ensuring that the second grinding mechanism 4 and the square hole grinding mechanism 7 can be normally arranged on the workbench 1. The setting of the front-back moving mechanism 8 solves the problem that the second grinding mechanism 4 and the square hole grinding mechanism 7 cannot be arranged side by side on the workbench 1 due to the small spacing between the round holes and the square holes on the left and right surfaces of the air path plate, thereby improving the applicability of the grinding equipment. In addition, in the square hole grinding mechanism 7, the structural design in which the output end of the first push cylinder 73 is arranged in a direction away from the clamping mechanism 2 can make the overall structure of the grinding station more compact and reduce the floor space.

[0028] like Figure 8As shown, in order to further optimize the square hole grinding mechanism 7, we have improved the structure of the square grinding brush 72 and the support frame 71. The square grinding brush 72 includes a square brush head 721 and a connecting block 722 fixedly connected between the square brush head 721 and the output end of the first push cylinder 73. A guide groove 74 is opened on the support frame 71 and a cushion block 75 and a second push cylinder 76 are provided. The guide grooves 74 are distributed on the left and right sides of the support frame 71 and are provided for positioning and inserting one end of the square brush head 721. The cushion block 75 is slidably set in the guide groove 74 and supported at the bottom of the square brush head 721 and the connecting block 722. The output end of the second push cylinder 76 is set in a direction away from the clamping mechanism 2 and is used to drive the cushion block 75 to move synchronously with the square brush head 721. This improvement improves the grinding accuracy and the compactness of the equipment structure by optimizing the design of the square grinding brush 72 and the support frame 71. Specifically, the combination of the square brush head 721 and the connecting block 722 allows the brush head to enter the square hole of the air circuit board more deeply, which can be adapted to the precise grinding of deeper square holes on the air circuit board. The guide groove 74 on the support frame 71 provides precise guidance for the positioning of the brush head, ensuring that the brush head always maintains the correct direction to prevent deviation during the grinding process. The setting of the pad 75 effectively prevents the brush head from sagging on one side of the connecting block 722, avoiding the reduction in grinding accuracy and damage to the air circuit board due to the sagging of the brush head. In addition, the output end of the second push cylinder 76 is set in a direction away from the clamping mechanism 2, so that the overall structure of the grinding station is more compact and space is saved.

[0029] like Figure 2 , Figure 5 and Figure 6As shown, in order to further improve the applicability and efficiency of the grinding station, so that the grinding station can be used for grinding the gas path plate with multiple circular holes on the upper and lower surfaces, in the present invention, a top grinding mechanism 9 is provided on the mounting seat 53, and the top grinding mechanism 9 includes a stand 91 vertically fixed on the mounting seat 53, a second multi-axis drive motor 92 and a lifting mechanism 93 arranged on the stand 91, and at least one rotating grinding brush 94 fixedly arranged at the output end of the second multi-axis drive motor 92 in a one-to-one correspondence, and the lifting mechanism 93 includes a second slider rail assembly 931 and a second lifting cylinder 932 arranged on the stand 91, and the output end of the second multi-axis drive motor 92 is downwardly arranged on the second slider rail assembly 931, and the second lifting cylinder 932 is used to drive the second multi-axis drive motor 92 to move up and down. Specifically, the second slider rail assembly 931 includes a pair of rails fixedly arranged on the stand 91 and a slider slidably arranged on the pair of rails, the second multi-axis drive motor 92 is fixedly arranged on the slider, and the output end of the second lifting cylinder 932 is fixedly connected to the slider. This improvement expands the function of the grinding station by adding a top grinding mechanism 9, and is capable of processing the grinding of circular holes on the upper and lower surfaces of the air circuit board. In this structure, the top grinding mechanism 9 and the first grinding mechanism 3 share a left and right feed linear module and a mounting seat 53, which simplifies the structure, reduces the cost, and makes the overall structure more compact. Among them, the structural design of arranging the top grinding mechanism 9 and the first grinding mechanism 3 on the same side of the clamping mechanism 2 leaves more space for other components, which is conducive to optimizing the overall structural layout. In addition, when there are multiple rows of circular holes arranged side by side on the upper and lower sides of the air circuit board, by arranging multiple rotating grinding brushes 94 at the output end of the second multi-axis drive motor 92, the synchronous grinding of the multiple rows of circular holes can be effectively performed.

[0030] like Figure 6 As shown, a dust removal duct 12 is fixedly provided on the vertical plate 551 through a bracket 11, one end of the bracket 11 is fixedly connected to the vertical plate 551, and the other end of the bracket 11 extends upward from the clamping mechanism 2, and the air outlet of the dust removal duct 12 is downwardly arranged at the other end of the bracket 11. After applying this structure, the dust removal duct 12 can blow away foreign matter such as grinding debris attached to the contact surface between the air path plate and the clamping mechanism 2, ensuring that the clamping mechanism 2 firmly clamps the air path plate and the grinding quality. In addition, the dust removal duct 12 and the first grinding mechanism 3 share a set of left and right movement control systems, which simplifies the structure of the grinding station, saves manufacturing costs, and improves the economic efficiency of the equipment.

[0031] Furthermore, a circulating water cooling station is provided under the workbench 1, and a water outlet running through the workbench 1 from top to bottom is provided. The circulating water cooling station comprises a water tank located below the water outlet and a water pump placed in the water tank. A hose is installed at the water outlet of the water pump, and the water outlet of the hose is placed above the workbench 1. When in use, the cooling water in the water tank is pumped out by the water pump, and the cooling water is led to multiple grinding mechanisms by the hose to cool the grinding brush. The cooling water flowing to the top of the workbench 1 is re-injected into the water tank through the water outlet on the workbench 1, thereby forming a circulating cooling water circuit. The circulating cooling water circuit can effectively reduce the heat accumulation in the grinding process, and the heat generated in the grinding process is taken away by cooling water, thereby reducing the temperature of the grinding brush and the air circuit plate, avoiding the influence of high temperature on the grinding effect, and improving the grinding efficiency and product quality. At the same time, the recycling of cooling water also effectively saves water resources.
