Description

Technical Field

[0001] This utility model belongs to the field of grinding machine baffle technology, and in particular relates to a protective baffle mechanism for a precision grinding machine. Background Technology

[0002] A grinding machine is a precision mechanical device that uses grinding wheels to grind the surface of a workpiece. Through high-precision grinding processes, it achieves the required dimensional accuracy and surface finish of the workpiece. However, during the grinding process, the high-speed rotating grinding wheel will cut the workpiece into fine chips or generate fragments upon collision. These flying debris have extremely high speed and kinetic energy under the action of centrifugal force. Once they leave the processing area, they can easily cause serious injury to the operator. To effectively avoid the risk of flying debris, the industry generally adopts protective measures such as installing baffles. However, most existing baffles are made of rigid materials. When faced with the impact of heavy objects, the rigid structure cannot effectively buffer the impact force and is prone to local deformation and cracking, resulting in a significant decrease in protective performance and making it difficult to meet the safety protection requirements in high-intensity processing scenarios.

[0003] To address these issues, we provide a precision grinding machine protective baffle mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a protective baffle mechanism for precision grinding machines. By using the hollow structure of the energy-absorbing plate to initially dissipate energy, the honeycomb buffer pad to disperse impact, and the multi-stage buffer design of the linkage between the buffer spring and the damper, the existing grinding machine baffle has limited protective performance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a protective baffle mechanism for a precision grinding machine, including a base frame and a sliding frame; the sliding frame is located on the top of the base frame, and buffers are fixedly connected to both sides of the sliding frame. An L-shaped mounting bracket is installed on the top of each of the two buffers, and a buffer plate is installed on the outside of the mounting bracket. An adjustment component for adjusting the distance between the buffer plate and the grinding wheel is provided on the top of the base frame. The buffer includes a slide plate fixedly connected to one side of the sliding frame, and the slide plate is in contact with the top of the base frame. A slider is slidably connected inside the slide plate, and a mounting bracket is fixedly connected to the top of the slider. A damper is fixedly connected inside the slide plate, and the slider is fixedly connected to the movable end of the damper. A buffer spring is movably sleeved on the outside of the damper. The buffer plate includes a fixed plate fixedly connected to the outside of the mounting frame. A buffer pad is fixedly connected to the side of the fixed plate away from the mounting frame. Fixed plates are installed on both sides of the fixed plate. An installation plate is installed inside the two fixed plates, and the buffer pad is located between the installation plate and the fixed plate. A hollow energy-absorbing plate is fixedly connected to the side of the installation plate away from the buffer pad.

[0006] The present invention is further configured such that the adjusting assembly includes a threaded sleeve fixedly connected inside the sliding frame and an adjusting motor fixedly connected to the top of the base frame. The top of the base frame is fixedly connected to mounting seats located at the front and rear ends of the sliding frame. The two mounting seats are rotatably connected to screws threaded into the threaded sleeve, and the screws are fixedly connected to the output end of the adjusting motor.

[0007] The present invention is further configured such that the side of the fixing plate facing the mounting bracket has two parallel sliding grooves, and the inside of the fixing plate has a slidably connected protrusion that is fixedly connected to the corresponding sliding groove.

[0008] The present invention is further configured such that each of the two fixed plates has a sliding opening on its opposite side, and the two ends of the mounting plate are respectively slidably connected to the inside of the two sliding openings.

[0009] The present invention is further configured such that the buffer pad is a honeycomb rubber pad.

[0010] The present invention is further configured such that two opposing limiting plates are fixedly connected to the top of the base frame, and the two sliding plates are respectively attached to the two limiting plates.

[0011] The present invention is further configured such that a plurality of reinforcing rods are fixedly connected inside the mounting bracket in a horizontally equidistant array.

[0012] This utility model has the following beneficial effects: 1. This utility model uses a hollow energy-absorbing plate to initially absorb some energy. The remaining impact force then acts on a buffer pad made of honeycomb rubber. The honeycomb buffer pad can further disperse and absorb the impact force. At the same time, the impact force is transmitted to the buffer through the mounting frame. The slider slides in the slide plate, compressing the buffer spring and driving the moving end of the damper. The elastic deformation of the buffer spring and the damping effect of the damper further buffer and consume the impact force, improving the impact resistance of the protective baffle mechanism and effectively reducing the impact of external impacts on the operation of the grinding machine and personnel safety.

[0013] 2. This utility model allows the damaged energy-absorbing plate to be removed by pulling the two ends of the mounting plate upwards along the fixing plates, thereby moving the mounting plate upwards. After the fixing plates are completely pulled out, the two fixing plates can be removed from the two ends of the mounting plate. Then, the energy-absorbing plate can be quickly replaced by reversing the above operation. The installation and disassembly process is simple and convenient, without the need for complicated tools, thus improving maintenance efficiency. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1 to 4This utility model is a protective baffle mechanism for a precision grinding machine, including a base frame 100 and a sliding frame 200; the sliding frame 200 is located on the top of the base frame 100, and buffers 300 are fixedly connected to both sides of the sliding frame 200. An L-shaped mounting bracket 400 is installed on the top of each of the two buffers 300, and a buffer plate 500 is installed on the outside of the mounting bracket 400. An adjustment component 600 for adjusting the distance between the buffer plate 500 and the grinding tool is provided on the top of the base frame 100. The buffer 300 includes a slide plate 301 fixedly connected to one side of the sliding frame 200, and the slide plate 301 is in contact with the top of the base frame 100. A slider 302 is slidably connected inside the slide plate 301, and the mounting bracket 400 is fixedly connected to the top of the slider 302. A damper 304 is fixedly connected inside the slide plate 301, and the slider 302 is fixedly connected to the movable end of the damper 304. A buffer spring 303 is movably sleeved on the outside of the damper 304. The buffer plate 500 includes a fixed plate 501 fixedly connected to the outside of the mounting frame 400. A buffer pad 502 is fixedly connected to the side of the fixed plate 501 facing away from the mounting frame 400. Fixed clamping plates 505 are installed on both sides of the fixed plate 501. A mounting plate 503 is installed inside the two fixed clamping plates 505, and the buffer pad 502 is located between the mounting plate 503 and the fixed plate 501. A hollow energy-absorbing plate 504 is fixedly connected to the side of the mounting plate 503 facing away from the buffer pad 502. Through multi-stage buffering, the impact resistance of the protective baffle mechanism is improved, and the impact of external impacts on the operation of the grinding machine and personnel safety is effectively reduced.

[0024] Specifically, the buffer pad 502 is a honeycomb rubber pad. The honeycomb structure of the buffer pad 502 has good elasticity and cushioning performance, which can further disperse and absorb impact force.

[0025] Furthermore, the mounting bracket 400 has multiple reinforcing rods 401 arranged equidistantly in a horizontal direction as internally fixed connections.

[0026] The operation process of this embodiment is as follows: When the grinding machine is running, if a workpiece or debris impacts the buffer plate 500, the impact force will first be transmitted to the energy-absorbing plate 504 of the buffer plate 500. The hollow structure of the energy-absorbing plate 504 can initially absorb some energy. Then, the remaining impact force acts on the buffer pad 502 made of honeycomb rubber. The honeycomb structure of the buffer pad 502 can further disperse and absorb the impact force. At the same time, the impact force is transmitted to the buffer 300 through the mounting bracket 400. The slider 302 slides in the slide plate 301, compressing the buffer spring 303 and driving the moving end of the damper 304 to move. The elastic deformation of the buffer spring 303 and the damping effect of the damper 304 buffer and consume the impact force again, protecting the safety of the grinding machine operator and surrounding equipment. Example

[0027] Please see Figure 1 and Figure 2 Based on the first specific embodiment, the adjustable distance assembly 600 includes a threaded sleeve 601 fixedly connected inside the sliding frame 200 and an adjusting motor 602 fixedly connected to the top of the base frame 100. The top of the base frame 100 is fixedly connected to mounting seats 603 located at the front and rear ends of the sliding frame 200. The two mounting seats 603 are rotatably connected to screws 604 threaded into the threaded sleeve 601, and the screws 604 are fixedly connected to the output end of the adjusting motor 602.

[0028] Specifically, the top of the base frame 100 is fixedly connected to two opposing limiting plates 101, and the two sliding plates 301 are respectively attached to the two limiting plates 101. The two opposing limiting plates 101 on the top of the base frame 100 are attached to the sliding plates 301 to limit the movement, ensuring that the sliding frame 200 moves smoothly along a straight line during the sliding process, avoiding deviation and ensuring the accuracy of adjustment.

[0029] The operation process of this embodiment is as follows: When it is necessary to adjust the distance between the buffer plate 500 and the mold, the adjustment motor 602 is started. The output end of the adjustment motor 602 drives the screw 604 to rotate. Since the screw 604 is threadedly connected to the threaded sleeve 601 inside the sliding frame 200, under the action of threaded transmission, the sliding frame 200 will slide along the top of the base frame 100, thereby driving the buffer 300, the mounting frame 400 and the buffer plate 500 installed on the sliding frame 200 to move as a whole, thereby realizing the adjustment of the distance between the buffer plate 500 and the mold. This allows the protective baffle mechanism to flexibly adapt to various processing scenarios and improves the versatility and practicality of the protective baffle mechanism. Example

[0030] Please see Figure 4 Based on specific embodiment one and specific embodiment two, the side of the fixing plate 501 facing the mounting bracket 400 has two parallel sliding grooves 501a, and the inside of the fixing plate 505 is fixedly connected to a protrusion 505a that is slidably connected to the inside of the corresponding sliding groove 501a. Each of the two fixed plates 505 has a sliding opening 505b on its opposite side, and the two ends of the mounting plate 503 are slidably connected to the inside of the two sliding openings 505b respectively.

[0031] The operation process of this embodiment is as follows: When it is necessary to replace the energy-absorbing plate 504, first pull the two ends of the mounting plate 503 upward along the fixing plates 505, and at the same time move the mounting plate 503 upward. After the fixing plates 505 are completely pulled out, remove the two fixing plates 505 from the two ends of the mounting plate 503, and the damaged energy-absorbing plate 504 can be removed. Then, the above operation is reversed to quickly replace the energy-absorbing plate 504. The installation and disassembly process is simple and convenient, without the need for complicated tools, which improves maintenance efficiency.
