Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of buffer mechanisms for grinding machines, and more specifically to buffer mechanisms for grinding machines. Background Technology
[0002] Existing grinding machines utilize the up-and-down swinging motion of a swing arm to continuously transfer workpieces from a transport trolley to the grinding area for grinding. After grinding, the workpiece is returned to the transport trolley for transport to the next process. In this process, the transport trolley first transports the workpiece to a designated position, then the swing arm swings upward to a designated position to grasp the workpiece, then swings downward to the grinding area for grinding. After grinding, it swings upward to a designated position again to facilitate the transport trolley grasping the ground workpiece, and new unground workpieces are placed back into the swing arm's grippers. This allows the swing arm to transfer workpieces to the grinding area for continuous operation, thus forming a continuous production line and improving workpiece processing efficiency.
[0003] During the swing arm's swing, to maintain a constant swing angle during upward swing and reduce the impact force upon impact, a buffer is typically installed at a designated location. The swing arm stops upon impacting the buffer, at which point it is positioned precisely where the trolley places and picks up the workpiece. However, under long-term operating conditions, the buffer, subjected to continuous impacts from the metal swing arm, undergoes deformation and displacement. These factors cause the swing arm to shift synchronously with the buffer after impact, preventing it from stopping at the designated position for placing and picking up the workpiece. This results in the workpiece being unable to be placed and processed normally, leading to production line interruptions or even equipment damage.
[0004] Existing buffer mechanisms for grinding machines are too simple and cannot maintain a stable buffering effect under prolonged impact from the swing arm. This makes the buffer components prone to deformation or displacement under prolonged impact from the swing arm, causing the swing arm to fail to return to the designated stopping position after the impact stops, ultimately leading to production line interruptions and equipment damage. Therefore, we propose a new buffer mechanism for grinding machines. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings mentioned in the background section and provide a buffer mechanism for grinding machines.

[0009] A buffer assembly is mounted on two opposing buffer blocks, the buffer assembly including two sliders for clamping the swing arm.
[0010] Preferably, the clamping assembly further includes a concave sealing cavity, which is formed inside a concave plate and adapted to the shape of the concave plate. The three buffer blocks are all fixedly connected to piston shafts on one side of the inner wall of the concave plate. The ends of the three piston shafts opposite to the buffer blocks pass through the concave plate and are connected to the piston of the concave sealing cavity. The end of the buffer block near the mounting plate located inside the concave sealing cavity is rotatably connected to two connecting blocks. The ends of the two connecting blocks away from the piston shafts are rotatably connected to piston blocks. The two piston blocks are connected to the piston of the concave sealing cavity.
[0011] Preferably, a first spring is sleeved on the outer side of one of the piston shafts adjacent to the mounting plate, and the two ends of the first spring are fixedly connected to the inner wall of the corresponding concave plate and the surface of the buffer block, respectively.
[0012] Preferably, the buffer assembly further includes two strip grooves, which are respectively formed on two opposite buffer blocks. The two sliders are respectively limited and slidably connected in the corresponding strip grooves. Both ends of the sliders are fixedly connected to the inner wall of the corresponding strip groove with a second spring. The outer surface of the slider protrudes outward from the strip groove and extends beyond the surface of the buffer block. A friction block is fixedly connected to the inner wall of the strip groove, and the surface of the friction block is set as a frosted surface.

During use, when the swing arm swings upward and enters the concave groove of the plate, it will collide with three buffer blocks, thereby triggering the relevant structure to perform damping movement, thus achieving the effect of buffering and unloading force. At the same time, the sliders mounted on the buffer blocks, together with the friction blocks, will further buffer the swing arm, thereby significantly reducing the impact force of the swing arm impact on the buffer mechanism, improving the service life of the buffer mechanism, and enabling it to remain without displacement or deformation under the impact of the swing arm for a long time, ensuring that the swing arm can accurately stop at the designated position after the impact.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Please see Figures 1-5 As shown, the present invention will describe the above technical solution in detail through the following embodiments:
[0028] A buffer mechanism for a grinding machine includes:
[0029] The clamping assembly 2 has a mounting plate 1 for mounting on a grinding machine fixedly connected to its bottom. The clamping assembly 2 includes a concave plate 21 for limiting the impact angle of the swing arm on the grinding machine and three buffer blocks 24 disposed in the concave plate 21 for reducing the impact potential energy of the swing arm.
[0030] A buffer assembly 3 is mounted on two opposing buffer blocks 24, and the buffer assembly 3 includes two sliders 32 for clamping the swing arm.
[0031] First, the buffer mechanism is installed on the wall panel on the side of the grinding equipment opposite to the swing arm via the mounting plate 1. During use, when the swing arm swings upward and enters the groove range of the concave plate 21, it will collide with the three buffer blocks 24 respectively, thereby achieving the effect of buffering and unloading force. At the same time, the slider 32 installed on the buffer block 24 will further buffer and dampen the swing arm, thereby greatly reducing the impact force of the swing arm impact on the buffer mechanism, improving the service life of the buffer mechanism, and enabling it to remain without displacement or deformation under the impact of the swing arm for a long time, ensuring that the swing arm can accurately stop at the designated position after the impact.
[0032] Please see Figures 1-2 As shown, the clamping assembly 2 also includes a concave sealing cavity 22, which is formed inside the concave plate 21 and is adapted to the shape of the concave plate 21. The three buffer blocks 24 are all fixedly connected to piston shafts 23 on one side of the inner wall of the concave plate 21. The ends of the three piston shafts 23 opposite to the buffer blocks 24 all pass through the concave plate 21 and are piston-connected to the concave sealing cavity 22. The end of the buffer block 24 near the mounting plate 1 located in the concave sealing cavity 22 is rotatably connected to two connecting blocks 28. The ends of the two connecting blocks 28 away from the piston shafts 23 are rotatably connected to piston blocks 29. The two piston blocks 29 are piston-connected to the concave sealing cavity 22.
[0033] Furthermore, during the impact, the swing arm will preferentially impact the buffer block 24 on the side adjacent to the mounting plate 1. The buffer block 24 will shift backward under the impact force, driving the corresponding piston shaft 23 to move into the concave sealing cavity 22. At this time, the backward-moving piston shaft 23 will cause the two connecting blocks 28 rotatably connected to it to expand, and push the piston block 29 rotatably connected to the connecting blocks 28 to expand relative to each other in the concave sealing cavity 22. During this period, the air in the concave sealing cavity 22 between the two piston blocks 29 will form a negative pressure due to the expansion of the two piston blocks 29, while the air in other positions of the concave sealing cavity 22 will increase to form a positive pressure, pushing the other two piston shafts 23 outward. The pressure change within 22 and the damping motion formed by the frictional resistance of the piston block 29 further effectively buffer the impact force brought by the swing arm. When the two opposing piston shafts 23 extend, they will drive the corresponding buffer blocks 24 to abut against and stably clamp the two sides of the swing arm, thereby achieving a three-sided buffering form. At this time, the greater the impact depth of the swing arm, the tighter the clamping between the two buffer blocks 24 and the two sides of the swing arm, which increases the friction force and reduces the impact potential energy of the swing arm, achieving a buffering effect. This reduces the huge impact force and vibration force generated during the impact of the swing arm, improves the stability of the swing arm after impact, and allows the swing arm to stably interact with the workpiece with the transport trolley after stopping.
[0034] Please see Figure 2 and Figure 5 As shown, a first spring 25 is sleeved on the outer side of the piston shaft 23 near the mounting plate 1. The two ends of the first spring 25 are fixedly connected to the inner wall of the corresponding concave plate 21 and the surface of the buffer block 24, respectively.
[0035] Furthermore, a first spring 25 is sleeved on the outside of the piston shaft 23 near the mounting plate 1, so that the buffer block 24 moving under the impact of the swing arm will compress the first spring 25 to produce compression deformation. This process can reduce the impact speed of the swing arm and avoid damage to the buffer block 24 under sudden impact. At the same time, when the first spring 25 resets, it can assist the swing arm to reset to the designated position.
[0036] Please see Figures 2-4As shown, the buffer assembly 3 also includes two strip grooves 31, which are respectively opened on two opposite buffer blocks 24. The two sliders 32 are respectively limited and slidably connected in the corresponding strip grooves 31. Both ends of the sliders 32 are fixedly connected to the inner wall of the corresponding strip grooves 31 with a second spring 33. The outer surface of the sliders 32 protrudes outward from the strip grooves 31 and extends outward from the surface of the buffer blocks 24. A friction block 35 is fixedly connected to the inner wall of the strip grooves 31, and the surface of the friction block 35 is set with a frosted surface. The buffer blocks 24 located in the strip grooves 31 have through grooves adapted to the friction blocks 35. The friction blocks 35 pass through the through grooves and are fitted and connected to the inner wall of the through grooves.
[0037] Furthermore, by setting the buffer component 3, when the two opposing buffer blocks 24 come into contact with the surfaces on both sides of the swing arm, the outwardly protruding slider 32 will preferentially contact the surface of the swing arm. Under the continuous push of the buffer block 24, it is stably clamped on both sides of the swing arm and moves back and forth with the swing arm in the direction of impact and the direction of reset to the designated position after impact. At this time, the two second springs 33 fixedly connected to both ends of the slider 32 undergo reciprocating compression deformation and tensile deformation, and continuously rub against the friction block 35. In this process, the impact force and speed of the swing arm before and after impact can be further buffered and decelerated. The damping motion is further used to enhance the buffer mechanism to buffer and weaken the impact force of the swing arm before and after impact, ensuring that the swing arm can stably stay in the designated position after impact and interact with the transport vehicle.
[0038] Please see Figure 4 As shown, both ends of the slider 32 are fixedly connected to a limiting shaft 34. The end of the limiting shaft 34 away from the slider 32 is inserted into the second spring 33 and passes through the strip groove 31.
[0039] Furthermore, by fixing the limiting shaft 34 to both ends of the slider 32 and passing through the second spring 33, the second spring 33 can be limited during deformation to avoid excessive bending and buffer failure. On the other hand, the stability of the slider 32 moving in the strip groove 31 is further improved.
[0040] Please see Figure 1 As shown, the buffer block 24 and the slider 32 are both fixedly connected to the surface of the swing arm with rubber buffer pads 26 for buffering and shock absorption.
[0041] In addition, by fixing rubber buffer pads 26 for buffering and shock absorption to the adjacent sides of the three buffer blocks 24 and the surfaces of the two sliders 32, on the one hand, the surface of the structure can be protected from damage by the impact of the swing arm under long-term impact, and on the other hand, the rubber buffer pads 26 made of rubber can improve the buffering and shock absorption effect of the buffer mechanism.
[0042] Please see Figure 5 As shown, magnetic blocks 27 are provided between the three buffer blocks 24 and the rubber buffer pad 26 to maintain the stability of the swing arm before and after impact.
[0043] Furthermore, by providing magnetic blocks 27 between the three buffer blocks 24 and the rubber buffer pad 26 to maintain the stability of the swing arm before and after impact, the magnetic attraction of the magnetic blocks 27 to the metal swing arm can enhance the attraction of the slider 32 to the swing arm before and after impact, thereby enhancing the stability of the swing arm during the buffering process.
[0044] It is worth noting that the three buffer blocks 24 are positioned to match the designated position that the swing arm needs to enter. In other words, when the first spring 25 is reset, the three buffer blocks 24 will adaptively push the swing arm to the designated position to interact with the transport vehicle.
[0045] The working principle of the buffer mechanism for the grinding machine in this embodiment is as follows: First, the buffer mechanism is installed on the wall plate on the side of the grinding equipment opposite to the swing arm via the mounting plate 1. During use, when the swing arm swings upward and enters the groove range of the concave plate 21, during the impact process, the swing arm will preferentially impact the buffer block 24 on the side adjacent to the mounting plate 1. The buffer block 24 will be displaced backward under the impact force, and drive the corresponding piston shaft 23 to move into the concave sealing cavity 22. At this time, the backward-moving piston shaft 23 will drive the two connecting blocks 28 rotatably connected to it to expand, and push the piston block 29 rotatably connected to the connecting block 28 to expand relative to each other in the concave sealing cavity 22. During this period, the air in the concave sealing cavity 22 between the two piston blocks 29 will form a negative pressure due to the expansion of the two piston blocks 29, and the concave sealing cavity 22... The air in other locations will increase to form positive pressure, pushing the other two piston shafts 23 to extend outward. The air pressure change in the concave sealing cavity 22 and the damping motion formed by the frictional resistance of the piston block 29 will further effectively buffer the impact force brought by the swing arm. When the two opposing piston shafts 23 extend, they will drive the corresponding buffer blocks 24 to abut against and stably clamp the two sides of the swing arm, thereby achieving a three-sided surrounding buffer form. At this time, the greater the impact depth of the swing arm, the tighter the clamping between the two relative buffer blocks 24 and the two sides of the swing arm will be, increasing the friction while reducing the impact potential energy of the swing arm, achieving a buffering effect. This reduces the huge impact force brought by the swing arm impact and the vibration force generated during the impact, improves the stability of the swing arm after impact, and allows the swing arm to stably interact with the workpiece with the transport trolley after stopping.
[0046] Meanwhile, with the buffer component 3, when the two relative buffer blocks 24 come into contact with the surfaces of the swing arm, the outwardly protruding slider 32 will preferentially contact the surface of the swing arm. Under the continuous push of the buffer block 24, it is stably clamped on both sides of the swing arm and moves back and forth with the swing arm in the direction of impact and the direction of reset to the designated position after impact. At this time, the two second springs 33 fixedly connected to both ends of the slider 32 undergo reciprocating compression deformation and tensile deformation, and continuously rub against the friction block 35. In this process, the impact force and speed of the swing arm before and after impact can be further buffered and decelerated. The damping motion is further used to enhance the buffer mechanism to buffer and weaken the impact force of the swing arm before and after impact, ensuring that the swing arm can stably stay in the designated position after impact and interact with the transport vehicle.
