Description

Technical Field

[0001] The utility model relates to the technical field of ceramic composite grinding wheels, in particular to node assembly equipment for ceramic composite grinding wheels. Background Art

[0002] Vitrified composite grinding wheels are high-performance grinding tools composed of a heat- and wear-resistant ceramic matrix and a high-hardness abrasive (such as diamond or cubic boron nitride). Combining the stability of ceramic with the efficient cutting performance of abrasives, they are suitable for high-precision and high-efficiency machining tasks and are widely used in machining and grinding hard materials.

[0003] The Chinese patent publication number CN208697203U discloses a node assembly device for a multi-node vitrified diamond composite grinding wheel. The device uses a PLC control system to coordinate the work of various components to achieve automated node assembly. It has high flexibility and is particularly suitable for mass production. It ensures uniform and efficient placement, improves the production efficiency and quality of multi-node vitrified diamond composite grinding wheels, and can also greatly save manpower and time. It is highly practical and has good promotion prospects.

[0004] However, the above patent can only stick the nodes one by one on the base, which is very inefficient. Especially for mass production and processing, the one-by-one sticking method obviously cannot meet the needs of fast production, which may lead to delivery delays and reduced market competitiveness. Utility Model Content

[0005] The purpose of the utility model is to provide a node assembly device for a ceramic composite grinding wheel to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0007] A node assembly device for a vitrified composite grinding wheel comprises a conveyor belt and a tray. A first placement slot is defined on one side of the tray's upper surface, within which a base disc is disposed. Multiple second placement slots are defined on the other side of the tray's upper surface, within which nodes are disposed. A U-shaped plate is mounted on the conveyor belt's upper surface via a movable mechanism. A first hollow disc and a second hollow disc are mounted at each end of the U-shaped plate. Multiple pouring nozzles are evenly mounted on the lower surface of the first hollow disc, and a glue injection hose is connected to the upper surface of the first hollow disc. Multiple vacuum suction cups are evenly mounted on the lower surface of the second hollow disc, and a vacuum tube is connected to the upper surface of the second hollow disc.

[0008] It can be seen that by driving the first hollow disk to move above the base disk through the moving mechanism, the purpose of gluing all the nodes on the base disk at one time can be achieved. The vacuum suction cup at the bottom of the second hollow disk is driven by the moving mechanism to paste all the nodes on the base disk at one time. Therefore, compared with the method of pasting one by one, the production cycle is greatly shortened and the overall production efficiency is improved. Moreover, since all the nodes are pasted on the base disk at the same time, the relative position and angle between the nodes can be ensured to be more accurate, avoiding the deviation that may occur when pasting one by one, thereby improving the quality of the product.

[0009] Furthermore, the moving mechanism includes a first electric push rod installed on one side of the conveyor belt, a first mounting block is installed at the end of the telescopic end of the first electric push rod, an L-shaped plate is installed on the upper surface of the first mounting block, a second electric push rod is installed on the upper surface of the L-shaped plate, a second mounting block is installed at the end of the telescopic end of the second electric push rod, a third electric push rod is installed on the upper surface of the second mounting block, and the end of the telescopic end of the third electric push rod is connected to the U-shaped plate.

[0010] When the first electric push rod is started, the U-shaped plate can be driven to move along the X-axis direction. When the second electric push rod is started, the U-shaped plate can be driven to move along the Y-axis. When the third electric push rod is started, the U-shaped plate can be driven to move along the Z-axis. Therefore, the position change of the first hollow disk and the second hollow disk can be achieved.

[0011] Furthermore, a fourth electric push rod is installed on the other side of the conveyor belt, and a mounting plate is provided at the end of the telescopic end of the fourth electric push rod. A threaded rod with a pair of reverse threads is rotatably installed inside the mounting plate, and nut seats are installed on the two reverse threads of the threaded rod. A splint is installed on the outer surface of the nut seat, and a motor is installed on the outer surface of the mounting plate, and the end of the motor output shaft is connected to the threaded rod.

[0012] When the conveyor belt moves the pallet to the specified position and stops, the position can be identified by an infrared sensor (not shown in the figure). However, since the conveyor belt has a certain inertia when it is paused, the position of the pallet may be offset. Therefore, the fourth electric push rod can be started to retract, driving the two clamps to move to both sides of the pallet width direction respectively, and then the motor is started. Due to the setting of the reverse thread, the two nut seats can move inward at the same time, and the two sides of the pallet can be clamped by the clamps to achieve the purpose of positioning and improve product processing accuracy.

[0013] Furthermore, a connecting rod is installed at the end of the telescopic end of the fourth electric push rod, a telescopic rod is installed on the outer surface of the connecting rod, the end of the telescopic rod is connected to the mounting plate, a spring is sleeved on the outer surface of the telescopic rod, and the two ends of the spring are respectively in contact with the connecting rod and the mounting plate.

[0014] When the two clamps clamp both sides of the pallet in the width direction, the fourth electric push rod continues to contract, thereby driving one end of the pallet in the length direction to abut against the side of the conveyor belt. At this time, the setting of the telescopic rod and the spring can not only play a buffering role, but also provide a certain telescopic space. At this time, both sides of the pallet in the width direction are clamped by the two clamps, and one side in the length direction abuts against the side of the conveyor belt. Through the three-sided positioning method, the position of the pallet can be accurately positioned, further improving the product processing accuracy.

[0015] Furthermore, two sliding rods are installed on the side surface of the conveyor belt, and the outer surfaces of the sliding rods are covered with sliding sleeves, and the ends of the sliding sleeves are connected to the mounting plate.

[0016] The setting of the slide rod and the slide sleeve can provide precise guidance for the movement of the mounting plate, ensuring the stability and linearity of the mounting plate during movement. This helps to reduce inaccurate positioning problems caused by offset or shaking, and improves the processing accuracy of the entire equipment.

[0017] Furthermore, a first slide groove is provided on the side surface of the conveyor belt, and the first mounting block is slidably connected to the first slide groove; a second slide groove is provided on the upper surface of the L-shaped plate, and the second mounting block is slidably connected to the second slide groove.

[0018] By setting the first slide groove and the second slide groove, the linearity and stability of the first mounting block and the second mounting block during movement can be ensured, which helps to reduce the problem of inaccurate positioning caused by offset or shaking, thereby improving the processing accuracy of the entire equipment.

[0019] Furthermore, diagonal braces are connected to the angles of the L-shaped plates.

[0020] The setting of the diagonal bracing rods provides additional support for the L-shaped plate, enhancing its structural stability. During the operation of the equipment, especially when moving at high speed or bearing large loads, the diagonal bracing rods can effectively prevent the L-shaped plate from deformation or twisting, ensuring the stability and reliability of the entire moving mechanism.

[0021] Furthermore, a rubber pad is provided on the outer surface of the splint, and an anti-slip pattern is provided on the outer surface of the rubber pad.

[0022] The provision of rubber pads and anti-slip grooves can increase the friction between the splint and the pallet, making the splint more stable and reliable when clamping the pallet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown, a node assembly device for a vitrified composite grinding wheel includes a conveyor belt 100 and a tray 101. A first placement slot 102 is defined on one side of the upper surface of the tray 101, with a base plate 103 disposed within the first placement slot 102. Multiple second placement slots 104 are defined on the other side of the upper surface of the tray 101, with nodes 105 disposed within the second placement slots 104. A U-shaped plate 106 is mounted on the upper surface of the conveyor belt 100 via a moving mechanism 200. A first hollow disk 107 and a second hollow disk 108 are mounted at either end of the U-shaped plate 106, respectively. Multiple pouring nozzles 109 are evenly mounted on the lower surface of the first hollow disk 107, and a glue injection hose 111 is connected to the upper surface of the first hollow disk 107. Multiple vacuum suction cups 110 are evenly mounted on the lower surface of the second hollow disk 108, and a vacuum tube 112 is connected to the upper surface of the second hollow disk 108.

[0031] When in use, the base plate 103 is placed in the first placement groove 102, the second placement groove 104 is placed in the node 105, and the pallet 101 is placed on the conveyor belt 100 for transportation. When the conveyor belt 100 transports the pallet 101 to the designated position and stops, the position can be identified by an infrared sensor (not shown in the figure). At this time, the first hollow plate 107 is driven by the moving mechanism 200 to move to the top of the base plate 103, and the pasting positions of all nodes 105 on the base plate 103 are glued at one time. Then, the vacuum suction cup 110 at the bottom of the second hollow plate 108 is driven by the moving mechanism 200 to suck all the nodes 105 at one time and paste them all on the base plate 103. Therefore, compared with the method of pasting one by one, the production cycle is greatly shortened and the overall production efficiency is improved. Moreover, since all the nodes 105 are pasted on the base plate 103 at the same time, the relative position and angle between each node 105 can be ensured to be more accurate, avoiding the deviation that may occur when pasting one by one, thereby improving the quality of the product.

[0032] Specifically, the moving mechanism 200 includes a first electric push rod 201 installed on a side of the conveyor belt 100, and a first mounting block 202 is installed at the end of the telescopic end of the first electric push rod 201, and an L-shaped plate 203 is installed on the upper surface of the first mounting block 202, and a second electric push rod 204 is installed on the upper surface of the L-shaped plate 203. The end of the telescopic end of the second electric push rod 204 is installed with a second mounting block 205, and the upper surface of the second mounting block 205 is installed with a third electric push rod 206. The end of the telescopic end of the third electric push rod 206 is connected to the U-shaped plate 106. When the first electric push rod 201 is started, the U-shaped plate 106 can be driven to move along the X-axis direction. When the second electric push rod 204 is started, the U-shaped plate 106 can be driven to move along the Y-axis. When the third electric push rod 206 is started, the U-shaped plate 106 can be driven to move along the Z-axis, thereby achieving the purpose of changing the positions of the first hollow disk 107 and the second hollow disk 108.

[0033] Specifically, a fourth electric push rod 300 is installed on the other side of the conveyor belt 100. A mounting plate 301 is provided at the end of the telescopic end of the fourth electric push rod 300. A threaded rod 302 with a pair of reverse threads is rotatably mounted inside the mounting plate 301. Nut seats 303 are installed on the two reverse threads of the threaded rod 302. A clamping plate 304 is installed on the outer surface of the nut seat 303. A motor 305 is installed on the outer surface of the mounting plate 301. The end of the output shaft of the motor 305 is connected to the threaded rod 302. When the conveyor belt 100 transports the pallet 101 to the designated position, After the conveyor belt 100 stops, its position can be identified by an infrared sensor (not shown in the figure). However, since the conveyor belt 100 has a certain inertia when it is paused, the position of the pallet 101 may be offset. Therefore, the fourth electric push rod 300 can be started to contract, driving the two clamps 304 to move to both sides of the width direction of the pallet 101 respectively, and then the motor 305 is started. Due to the setting of the reverse thread, the two nut seats 303 can move inward at the same time, and the two sides of the pallet 101 are clamped by the clamps 304 to achieve the purpose of positioning and improve the product processing accuracy.

[0034] The two ends of the spring 402 are respectively in contact with the connecting rod 400 and the mounting plate 301. When the two clamping plates 304 clamp the two sides of the pallet 101 in the width direction, the fourth electric push rod 300 continues to retract, thereby driving one end of the pallet 101 in the length direction to abut against the side of the conveyor belt 100. At this time, the arrangement of the telescopic rod 401 and the spring 402 not only plays a buffering role, but also provides a certain amount of telescopic space. At this time, the two sides of the pallet 101 in the width direction are clamped by the two clamping plates 304, and one side in the length direction abuts against the side of the conveyor belt 100. Through the three-sided positioning method, the position of the pallet 101 can be accurately positioned, thereby further improving the product processing accuracy.

[0035] Specifically, two sliding bars 500 are installed on the side surface of the conveyor belt 100, and the outer surface of the sliding bar 500 is provided with a sliding sleeve 501, and the end of the sliding sleeve 501 is connected to the mounting plate 301. Through the setting of the sliding bar 500 and the sliding sleeve 501, precise guidance can be provided for the movement of the mounting plate 301, ensuring the stability and linearity of the mounting plate 301 during the movement, which helps to reduce the problem of inaccurate positioning caused by offset or shaking, and improves the processing accuracy of the entire equipment.

[0036] Specifically, a first slide groove 600 is provided on the side surface of the conveyor belt 100, and the first mounting block 202 is slidably connected to the first slide groove 600. A second slide groove 601 is provided on the upper surface of the L-shaped plate 203, and the second mounting block 205 is slidably connected to the second slide groove 601. Through the setting of the first slide groove 600 and the second slide groove 601, the linearity and stability of the first mounting block 202 and the second mounting block 205 during the movement can be ensured, which helps to reduce the problem of inaccurate positioning caused by offset or shaking, thereby improving the processing accuracy of the entire equipment.

[0037] Specifically, a diagonal support rod 700 is connected at the angle of the L-shaped plate 203. The setting of the diagonal support rod 700 provides additional support for the L-shaped plate 203, thereby enhancing its structural stability. During the operation of the equipment, especially when moving at high speed or bearing a large load, the diagonal support rod 700 can effectively prevent the L-shaped plate 203 from deformation or twisting, thereby ensuring the stability and reliability of the entire moving mechanism 200.

[0038] Specifically, the outer surface of the clamping plate 304 is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-slip grooves. The setting of the rubber pad and the anti-slip grooves can increase the friction between the clamping plate 304 and the pallet 101, making the clamping plate 304 more stable and reliable when clamping the pallet 101.

[0039] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
