[0028] A pushing device for pushing the placement plate 3 is provided at one end of the conveying table 2, and the pushing device includes a telescopic device 12, and the telescopic device 12 is fixedly arranged on the workbench 1, and the telescopic end of the telescopic device 12 is fixedly connected with a pushing plate 13, through the pushing plate 13, the placement plate 3 located in the initial area of ​​the conveying table 2 can be pushed in the direction of the pressing mechanism, after the placement plate 3 is pushed out to the initial area, the pushing plate 13 is reset, and then the new placement plate 3 will enter the initial area, and then the new placement plate 3 will be pushed, and the new placement plate 3 will continue to push the previous placement plate 3, during the reciprocating motion of the pushing plate 13, the template 4 placed on the conveying table 2 can be pushed into the pressing station one by one, so that the grinding wheel can be pressed in batches, thereby improving the production efficiency of the grinding wheel.

[0029] In this embodiment, a feed trough is provided at the rear side of the right end of the conveying platform 2, and a previous conveying station for placing the plate 3 is provided outside the feed trough. The plate 3 is conveyed to the conveying platform 2 after passing through the previous conveying station.

[0030] A pressing mechanism is fixedly arranged on the workbench 1, and the pressing mechanism includes a vertical frame 6, a driving plate 8 is slidably connected to the vertical frame 6 and driven by a hydraulic device 7, a pressing plate 9 is fixedly connected to the bottom of the driving plate 8, and a pressing plate 11 corresponding to the template 4 is fixedly connected to the bottom of the pressing plate 9 through a movable column 10, which is used to press the pad body 5 downward. Through the hydraulic device 7, the driving plate 8 drives the pressing plate 9, the movable column 10 and the pressing plate 11 to move downward until the pressing plate 11 presses the pad body 5 downward, so that the pad body 5 presses the grinding wheel powder in the template 4, thereby improving the grinding wheel pressing effect.

[0031] The frame 6 includes a bottom plate, a top plate and columns. The bottom plate is fixedly connected to the workbench 1, and the top plate is arranged above the conveying platform 2. The top plate and the bottom plate are fixedly connected by a plurality of columns. The bottom plate, the top plate and the columns improve the stability of the driving plate 8 when it moves.

[0032] The driving plate 8 is provided with a slide groove, in which a sliding sleeve 14 is fixedly connected. The sliding sleeve 14 is slidably sleeved on the column. Through the sliding sleeve 14, it can better cooperate with the column, thereby improving the stability of the driving plate 8.

[0033] A buffer cavity 15 is provided at the bottom of the pressing plate 9, and a cavity cover 16 is movably connected to the bottom of the buffer cavity 15. A movable groove for the movable column 10 to pass through is provided on the cavity cover 16. The top of the movable column 10 is connected to the buffer cavity 15 through a buffer mechanism. The buffer mechanism can provide a buffering effect when the pressing plate 11 presses down the pad body 5, thereby preventing the pressing plate 11 from applying a large force to the pad body 5, which affects the pressing effect of the grinding wheel powder.

[0034] The buffer mechanism includes a sliding plate 17 and a damping buffer 18. The sliding plate 17 is fixedly connected to the movable column 10 via a first connecting flange, one end of the damping buffer 18 is fixedly connected to the sliding plate 17 via a second connecting flange, and the other end of the damping buffer 18 is fixedly connected to the top wall of the buffer cavity 15 via a third flange. Through the sliding plate 17, the two movable columns 10 can drive the pressure plate 11 to move downward or upward at the same time. Through the damping buffer 18, the sliding plate 17 can be buffered, so that the pressure plate 11 can have a buffering effect when pressing down the pad body 5.

[0035] In this embodiment, a plurality of damping buffers 18 are provided, and the plurality of damping buffers 18 are distributed on the sliding plate 17 at intervals.

[0036] The end of the sliding plate 17 is fixedly connected to the limit block 19, and the inner wall of the buffer cavity 15 is provided with a limit groove 20 for the limit block 19 to slide. By sliding the limit groove 20, the sliding plate 17 can be placed in the buffer cavity 15, and it is convenient to limit the sliding plate 17, further increasing the stability of the movable column 10 and the pressure plate 11 when moving.

[0037] The working principle of the utility model is as follows: through the control system, after the grinding wheel powder is evenly spread inside the template 4, the previous conveying station conveys the placement plate 3 to the placement table, and the telescopic device 12 is started, so that the push plate 13 pushes the placement plate 3 from the starting area on the placement table to the next area to the left, and then the telescopic device 12 is reset. At the same time, the previous conveying station pushes the new placement plate 3 onto the conveying table 2. Similarly, the push plate 13 pushes the new placement plate 3. In this way, the placement plate 3 on the conveying table 2 can be conveyed to the bottom of the pressing mechanism;

[0038] While the pushing plate 13 pushes the placement plate 3 from the initial area to the next area, the mechanical gripper is then started to place the pad body 5 into the template 4 in sequence, so that the pad body 5 preliminarily presses the grinding wheel powder in the template 4;

[0039] After the placement plate 3 is pushed to the bottom of the pressing mechanism, the hydraulic device 7 is started, so that the driving plate 8 drives the pressing plate 9, the movable column 10 and the pressing plate 11 to move downward, so that the pressing plate 11 presses down the pad body 5. At this time, the pad body 5 presses the grinding wheel powder. At the same time, the pressing plate 11 is pressed downward, so that the movable column 10 can drive the sliding plate 17 to move downward, so that the sliding plate 17 presses the damping buffer 18. After the damping buffer 18 reaches the set pressure, the hydraulic device 7 stops the pressing operation. After the pressing time is reached, the hydraulic device 7 is reset, so that the pressing plate 11 moves upward and separates from the pad body 5.

[0040] The template 4 that has been pressed with the grinding wheel powder pushes the pressed placement plate 3 to the next station during the subsequent interval pushing process of the placement plate 3.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
