Description

Technical Field

[0001] This application relates to the field of automated production, specifically to a grinding machine with automatic loading and unloading. Background Technology

[0002] A grinding machine is a machine tool that uses abrasives (such as grinding wheels and abrasive belts) to perform precision machining on the surface of a workpiece. It removes material through the cutting action of abrasive grains to achieve a high-precision, low-roughness surface quality.

[0003] Because cylindrical materials tend to roll during horizontal transport, mechanical grippers are typically used to hold them during grinding before transporting them to the grinding area of ​​the grinding machine. For materials whose initial position is far from the grinding area, the travel range of the mechanical grippers needs to be set to a longer distance. However, while this method solves the loading and unloading problem, it is costly and difficult to maintain. Therefore, it is necessary to design an automatic loading and unloading grinding machine to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies by designing an automatic loading and unloading grinding machine that first transports the material to be ground to a position close to the grinding machine body via a material transport device, then transports the material to the grinding area via a loading and unloading device, and finally places the material into a post-grinding material transport device after grinding. This solves the problem of needing to set a gripper with a long stroke range to hold the material.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] An automatic loading and unloading grinding machine includes a grinding machine body, a material transport device for grinding is provided on the right side of the grinding machine body, a material loading and unloading device is provided above the grinding machine body, the front part of the material transport device for grinding is set within the travel range of the material loading and unloading device, a preset distance is between the material loading and unloading device and the grinding machine body, and a post-grinding material transport device is provided on the left side of the grinding machine body, the front part of the post-grinding material transport device is set within the travel range of the material loading and unloading device.

[0007] Preferably, the material transport device includes a frame, sprockets, a chain, and a support block. A rotating shaft is rotatably connected to the inner wall of the frame. Two rotating shafts are provided. The outer wall of each rotating shaft is fixedly connected to the inner wall of the sprocket. Two sprockets are provided on the outside of each rotating shaft, and the two sprockets are symmetrically arranged about the midpoint of the rotating shaft in the left-right direction. The axis of the rotating shaft coincides with the axis of the sprocket. The chain is externally meshed with the sprockets. An assembly plate is fixedly connected to the side of the chain away from the center of the frame. The side of the assembly plate near the center of the frame is fixedly connected to the support block. A V-shaped groove is formed at the top center of the support block. A drive assembly is provided inside the frame.

[0008] Preferably, the drive assembly includes a motor, the outer wall of the motor is fixedly connected to the inner wall of the frame, and the output shaft of the motor is fixedly connected to the right end of the front rotating shaft.

[0009] Preferably, the loading and unloading device includes an electric track, the electric track has two movers, the movers of the electric track are fixedly connected to a mounting plate, the front surface of the mounting plate is fixedly connected to an electric cylinder, the output shaft of the electric cylinder is fixedly connected to a mounting base, and the mounting base is provided with a clamping assembly inside.

[0010] Preferably, the clamping assembly includes an electric push rod, a sliding plate, a clamping plate, a slider, and a spring. The top end of the electric push rod is fixedly connected to the inner wall of the mounting base. The output shaft of the electric push rod is fixedly connected to the upper surface of the sliding plate. The outer wall of the sliding plate is slidably connected to the inner wall of the mounting base. A push block is fixedly connected to the lower surface of the sliding plate. The inner wall of the mounting base is slidably connected to the outer wall of the slider. The lower surface of the slider is fixedly connected to the top end of the clamping plate. The side of the slider near the middle of the mounting base is elastically connected to the inner wall of the mounting base by a spring.

[0011] Preferably, the post-grinding material transport device includes a belt conveyor, which is located on the left side of the grinding machine body.

[0012] Preferably, a control strip is fixedly connected to the upper surface of the frame, and the number of the control strips is set to two, with the two control strips arranged symmetrically about the center line of the frame in the left-right direction.

[0013] Preferably, the mounting frame includes a mounting bracket consisting of a long horizontal bar and two short bars perpendicular to the horizontal bar. The right short bar of the mounting bracket is fixedly connected to the upper surface of the frame near the right side, and the left short bar of the mounting bracket is fixedly connected to the right surface of the belt conveyor. The front side of the horizontal bar of the mounting bracket is fixedly connected to the outer wall of the electric track.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] 1. This application adopts the method of first transporting the material to be ground to the travel range of the loading and unloading material device through the material transport device, then transferring the material to the grinding range of the grinding machine body through the loading and unloading material device, and after grinding is completed, transferring the material to the post-grinding material transport device through the loading and unloading material device, and finally transporting the material to the next processing area through the post-grinding material transport device, thereby achieving the effect of shortening the travel range required for the material to move when loading and unloading materials.

[0016] 2. By setting up support blocks and V-grooves, this application ensures that during the process of moving materials from a distance to within the travel range of the upper and lower material handling device, the materials are less likely to roll because they are in the V-grooves, thus ensuring that the position of the materials is fixed after they are transported to within the travel range of the upper and lower material handling device, which facilitates subsequent loading and unloading of materials.

[0017] 3. By setting different distances between the front and rear of the control bar, this application ensures that the material can gradually move to the center of the frame as it moves from back to front, while in contact with the control bar. This ensures that the material is positioned more accurately after being transported within the travel range of the loading and unloading device, facilitating the loading and unloading of materials.

[0018] 4. By setting up two movers and two sets of clamping components on the electric track, it is ensured that when the material that has been ground is unloaded, the next material can be clamped and loaded by another set of clamping components, thus achieving the effect of saving work efficiency.

Detailed Implementation

[0027] Reference Figures 1-7 An automatic loading and unloading grinding machine includes a grinding machine body 1 for grinding material 6. A material transport device 2 is provided on the right side of the grinding machine body 1, and a loading and unloading device 3 is provided above the grinding machine body 1. The loading and unloading device 3 is used to move the material 6 to be ground within its travel range to the grinding area of ​​the grinding machine body 1, and to remove the ground material 6 from the grinding area of ​​the grinding machine body 1. The front part of the material transport device 2 is set within the travel range of the loading and unloading device 3, and there is a preset distance between the loading and unloading device 3 and the grinding machine body 1. A post-grinding material transport device 4 is provided on the left side of the grinding machine body 1. The post-grinding material transport device 4 is used to transport the ground material 6 to the next processing area. The front part of the post-grinding material transport device 4 is set within the travel range of the loading and unloading device 3.

[0028] In this embodiment, during use, the material transport device 2 first stably transports the material 6 to a position within the travel range of the loading / unloading material device 3. Then, the loading / unloading material device 3 transports the material 6 to the grinding area of ​​the grinding machine body 1. After grinding, the material 6 is transferred again from the grinding area of ​​the grinding machine body 1 to the conveying area of ​​the post-grinding material transport device 4 via the loading / unloading material device 3, thus transporting the material 6 to the next activity area.

[0029] As a preferred embodiment, the material transport device 2 includes a frame 21 for mounting the components required for transporting the material to be ground 6, sprockets 22, chains 23, and support blocks 25. A rotating shaft 27 is rotatably connected to the inner wall of the frame 21. Two rotating shafts 27 are provided, and their outer walls are fixedly connected to the inner walls of the sprockets 22. Each rotating shaft 27 has two sprockets 22 on its exterior. This arrangement of the rotating shafts 27 ensures that the two sprockets 22 located at the front or rear can move in unison. The chain rotates rapidly, and the two sprockets 22 are symmetrically arranged about the midpoint of the shaft 27 in the left and right directions. The axis of the shaft 27 coincides with the axis of the sprocket 22. The chain 23 is externally engaged with the sprocket 22. When the sprocket 22 rotates, the chain 23 moves with the rotation of the sprocket 22. An assembly plate 24 is fixedly connected to the side of the chain 23 away from the middle of the frame 21. The inner wall of the assembly plate 24 has holes for mounting the chain 23 on the outside. The holes in the inner wall of the assembly plate 24 pass through for connecting... The multi-link chain rod is fixedly connected to the support block 25 on the side of the assembly plate 24 near the middle of the frame 21. The support block 25 has a V-shaped groove 26 at the top center. The V-shaped groove 26 ensures that the rod-shaped material 6 cannot rotate after being placed inside, achieving a stable transportation effect. The frame 21 is equipped with a drive assembly 28. By placing the material 6 in the V-shaped groove 26 at the top of the support block 25 on the rear side and then starting the drive assembly 28, the drive assembly 28 can drive the rotating shaft 27 to rotate. The rotation of the rotating shaft 27 drives the sprocket 22 to rotate. When the sprocket 22 rotates, it drives the chain 23 in the upper rear side to move from back to front, thereby causing the chain 23 to drive the assembly plate 24 to move forward. The assembly plate 24 then drives the support block 25 to move forward. Since the material 6 is in the V-shaped groove 26 at the top of the support block 25, the material 6 moves forward with the support block 25 until it moves within the stroke range of the upper and lower material handling device 3.

[0030] As a preferred embodiment, the drive assembly 28 includes a motor 281, the outer wall of which is fixedly connected to the inner wall of the frame 21, and the output shaft of the motor 281 is fixedly connected to the right end of the front rotating shaft 27. The rotation of the output shaft of the motor 281 drives the front rotating shaft 27 to rotate.

[0031] As a preferred embodiment, the loading / unloading device 3 includes an electric track 31 with two movers. This arrangement ensures that the loading / unloading device 3 can simultaneously clamp the next material to be ground while grinding the previous one, thus saving time. A mounting plate 32 is fixedly connected to the movers of the electric track 31. An electric cylinder 33 is fixedly connected to the front surface of the mounting plate 32. The output shaft of the electric cylinder 33 is fixedly connected to a mounting base 34. A clamping assembly 35 is installed inside the mounting base 34. The electric cylinder 33, along with the mounting base 34 and the clamping assembly, allows for precise control of the material. 35 can move up and down. By moving the right-side mover of the electric track 31 to the right, it drives the mounting plate 32 to move to the right. When the mounting plate 32 is directly above the frame 21, the electric cylinder 33 drives the mounting base 34 and the clamping assembly 35 to move downward together. When it moves close to the material to be processed 6, the clamping assembly 35 clamps the material 6. After clamping, the electric cylinder 33 first moves the mounting base 34, the clamping assembly 35 and the clamped material 6 upward together. Then, the right-side mover of the electric track 31 drives the mounting plate 32, the electric cylinder 33, the mounting base 34 and the clamping assembly 35 to move upward together. The components 35 move together towards the grinding area of ​​the grinding machine body 1. Once at this position, the electric cylinder 33 drives the mounting base 34 and clamping assembly 35 downwards. When the material 6 is positioned precisely in the grinding area, the clamping assembly 35 releases the material 6, allowing it to be ground by the grinding machine body 1. After grinding, the left-side mover of the electric track 31 moves to the right, causing the mounting plate 32 to move to the right. When the mounting plate 32 is positioned directly above the grinding area of ​​the grinding machine body 1, the electric cylinder 33 is activated, causing its output shaft to drive the mounting base 34 and clamping assembly 35 downwards. The clamping component 35 moves downward together, and after moving to the bottom, the clamping component 35 clamps the ground material 6. After clamping, the electric cylinder 33 drives the mounting base 34 and the clamping component 35 to move upward together. After moving to the top, the left mover of the electric track 31 drives the mounting plate 32 to move to the left until it moves above the post-grinding material transport device 4. When it moves to this position, the electric cylinder 33 drives the mounting base 34 and the clamping component 35 to move downward together until the material 6 is placed in the transport area of ​​the post-grinding material transport device 4, and then the clamping component 35 releases the material 6.

[0032] In a preferred embodiment, the clamping assembly 35 includes an electric push rod 351, a sliding plate 352, a clamping plate 353, a slider 356, and a spring 354. The top end of the electric push rod 351 is fixedly connected to the inner wall of the mounting base 34, and the output shaft of the electric push rod 351 is located below it. The output shaft of the electric push rod 351 moves vertically. The output shaft of the electric push rod 351 is fixedly connected to the upper surface of the sliding plate 352, and the outer wall of the sliding plate 352 is slidably connected to the inner wall of the mounting base 34. The sliding direction relative to the inner wall of the mounting base 34 is up and down. A push block 355 is fixedly connected to the lower surface of the slide plate 352. The push block 355 is a right-angled triangle, and the lower side of the push block 355 near the inner side of the mounting base 34 is set as an inclined surface. The inner wall of the mounting base 34 is slidably connected to the outer wall of the slider 356. The slider 356 slides left and right relative to the mounting base 34. The lower surface of the slider 356 is fixedly connected to the top of the clamping plate 353. The slider 356 is located near the middle of the mounting base 34. One side is elastically connected to the inner wall of the mounting base 34 by a spring 354. One end of the spring 354 is fixedly connected to the side of the slider 356 near the middle of the mounting base 34, and the other end of the spring 354 is fixedly connected to the inner wall of the mounting base 34. When the output shaft of the electric push rod 351 moves downward, the slide plate 352 moves downward under force, thereby driving the push block 355 to move downward. During the downward movement, the inclined surface of the push block 355 pushes the slider 356, causing it to move towards the middle of the mounting base 34. This causes the slider 356 to drive the clamping plate 353 to move towards the middle of the mounting base 34, so that the two clamping plates 353 can clamp the material 6 by moving closer to each other. When the output shaft of the electric push rod 351 moves upward, the slide plate 352 moves upward, thereby driving the push block 355 to move upward. When the push block 355 moves upward and no longer contacts the slider 356, the slider 356 moves away from the material 6 under the action of the spring 354, thus releasing the material 6.

[0033] As a preferred embodiment, the post-grinding material transport device 4 includes a belt conveyor 41, which is located on the left side of the grinding machine body 1. The belt conveyor 41 is used to transport the ground material 6 to the next processing area.

[0034] As a preferred embodiment, a control strip 29 is fixedly connected to the upper surface of the frame 21. Two control strips 29 are arranged symmetrically about the centerline of the frame 21 in the left-right direction. Each control strip 29 has two horizontal sections on the left and right surfaces of the frame 21 and one inclined section. The distance between the front horizontal sections of the two control strips 29 is less than the distance between the rear horizontal sections. When the material 6 is placed in the V-shaped groove 26 above the support block 25 from the rear, since the material 6 is at a larger distance between the two control strips 29, there is greater tolerance when placing the material 6. That is, it is not necessary to ensure that the material 6 is exactly in the center of the frame 21. As the material 6 moves, when it reaches the junction of the front and rear sides of the control strip 29, the material 6 can move towards the center of the frame 21 under the push of the inclined surface of the control strip 29 until it is exactly in the center of the frame 21, achieving the positioning effect of the material 6.

[0035] As a preferred embodiment, the mounting frame 5 is provided. The mounting frame 5 consists of a long horizontal bar and two short bars perpendicular to the horizontal bar. This shape ensures that the material handling device 3 can be installed above the grinding area of ​​the grinding machine body 1. The right short bar of the mounting frame 5 is fixedly connected to the upper surface of the frame 21 near the right side. The left short bar of the mounting frame 5 is fixedly connected to the right surface of the belt conveyor 41. The front side of the horizontal bar of the mounting frame 5 is fixedly connected to the outer wall of the electric track 31.
