Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] See Figures 1 to 4This utility model provides a feeding device for a ceramic internal grinding mill, including a vertical mounting frame 5, a mounting frame 22, and a positioning frame 13. A lifting mounting plate 6 is located on the right side of the vertical mounting frame 5, and the mounting frame 22 is located on the right side of the lifting mounting plate 6. A groove is located at the center of the right end face of the mounting frame 22, and a sliding frame 23 is located within the groove. A movable frame 7 is located above the sliding frame 23, and a threaded guide cylinder is located on the movable frame 7. A rotating screw 9 is located inside the threaded guide cylinder, and a servo motor 8 is located below the rotating screw 9. A lifting adjustment plate 10 is fitted onto the rotating screw 9, and a connecting rod 11 is located at the other end of the lifting adjustment plate 10. An L-shaped connecting seat 12 is located at the bottom of the connecting rod 11, and the L-shaped connecting seat 12 is fixedly connected to the positioning frame 13. The feeding device is fixedly installed on the internal grinding equipment via the vertical mounting frame 5, supporting the stable installation of the lifting mounting plate 6. The mounting frame 22 is fixedly installed... On the lifting plate 6, the internal grinding equipment supports the mounting frame 22. The mounting frame 22 establishes a limiting installation for the sliding frame 23 by setting a sliding groove. The top of the sliding frame 23 is fixed to the connection with the moving frame 7. The moving frame 7 limits the installation of the rotating screw 9 by a threaded guide cylinder. The servo motor 8 receives the control command and rotates to output a certain amplitude, so that the rotating screw 9 rotates the same number of times under the rotational force, generating a relative displacement between it and the lifting adjustment plate 10. The axial output of the servo motor 8 is converted into the lifting displacement of the moving frame 7. When the feeding device needs to generate relative movement to the workpiece chuck 28, the servo motor 8 rotates to change the distance between the moving frame 7 and the lifting adjustment plate 10, that is, it drives the sliding frame 23 to move in the sliding groove. The moving frame 7 realizes the lifting control of the sliding frame 23, so as to make the feeding device move away from or closer to the workpiece chuck 28.

[0026] The positioning frame 13 is fixedly connected to the rotating device of the internal grinding equipment. That is, the positioning frame 13 establishes support control for the L-shaped connecting seat 12, and works with the connecting rod 11 to support the stable setting of the lifting adjustment plate 10. During the rotation of the servo motor 8, the lifting adjustment plate 10 will not be displaced, ensuring the accuracy of the control output of the lifting component.

[0027] See Figure 2The sliding frame 23 has a guide tube 24 at its bottom, with a push-out port at its bottom. A feed chute 25 is located at the front of the sliding frame 23. A first through hole is located at the bottom of the front panel of the sliding frame 23, and a second through hole is located in the center of the bottom panel. The sliding frame 23 drives the guide tube 24 to move up and down, aligning the push-out port at the bottom of the guide tube 24 with the center of the workpiece clamp 28. When a loading signal is input at the control terminal, the servo motor 8 rotates, causing the sliding frame 23 to move down to the set position. At this time, the workpiece to be ground is placed into the feed trough 25 by the feeding device. The feed trough 25 is inclined to the rear, so that the workpiece can be slidably conveyed to the first through hole, enter the second through hole at the bottom of the sliding frame 23, and then fall into the guide tube 24 from the second through hole. The workpiece continues to fall into the push port in the guide tube 24. The workpiece port is set directly opposite the workpiece chuck 28. The push frame 20 is rotated to the left under force, and the push end 21 quickly pushes the workpiece into the workpiece chuck 28, realizing the loading process of the workpiece.

[0028] A connecting sleeve is provided on the connecting rod 11, and a guide connecting frame 14 is provided on the right side of the connecting sleeve. A cylinder mounting seat 15 is provided behind the guide connecting frame 14. A pusher cylinder 16 is provided at the bottom of the cylinder mounting seat 15. The pusher cylinder 16 is movably connected to a guide seat 17 through four sets of guide rods. The guide connecting frame 14 is fixedly connected to the cylinder mounting seat 15. The left end of the cylinder mounting seat 15 is fixedly installed on the right end panel of the sliding frame 23 by bolts. That is, the cylinder mounting seat 15 and its components move up and down synchronously with the sliding frame 23. The front end of the cylinder mounting seat 15 is connected to the guide connecting frame 14. That is, during the feeding and lifting process of the cylinder mounting seat 15, it drives the guide connecting frame 14 to achieve the same amplitude lifting and lowering movement. The guide connecting frame 14 is sleeved with the connecting rod 11 through the connecting sleeve, which can realize the guiding control of the connecting rod 11 on the guide connecting frame 14 through the connecting sleeve, thereby enhancing the accuracy of the lifting and lowering of the sliding frame 23 and the cylinder mounting seat 15.

[0029] The cylinder mounting seat 15 fixes the setting of the pusher cylinder 16. The pusher cylinder 16 is installed with the guide seat 17 through the guide rod. The left end wall plate of the guide seat 17 is connected to the sliding groove setting frame of the mounting frame 22 by bolts. That is, during the lifting and lowering operation of the sliding frame 23 and its components, the guide seat 17 does not move. It can provide guidance control for the movement of the pusher cylinder 16, limit the lifting and lowering space of the pusher cylinder 16, and realize the auxiliary limit control of the pusher cylinder 16 by the mounting frame 22.

[0030] The pusher cylinder 16 has an extension rod 18 at its telescopic end, and a pressing end 19 at the bottom of the extension rod 18. When the workpiece falls to the push port of the guide tube 24, the pusher cylinder 16 receives the push command and controls the extension rod 18 to extend a set distance. The pressing end 19 acts to generate a thrust on the top contact end of the pusher frame 20, pushing the pusher frame 20 to rotate to the left around the pin axis, and quickly pushes the workpiece in the push port into the workpiece chuck 28, thus realizing the feeding process of the workpiece.

[0031] The bottom of the pressing end 19 is fitted with an anti-collision rubber sleeve. The anti-collision rubber sleeve can reduce the negative impact of the impact force of the pressing end 19 on itself and the contact end of the pusher frame 20. While realizing the pushing control of the pusher frame 20, it reduces the damage to the contact end of the pressing end 19 and the pusher frame 20, and extends the service life of the two sets of structures.

[0032] The sliding frame 23 has a slot, and a pin is longitudinally and movably connected in the middle of the slot. A pusher frame 20 is fixedly sleeved on the pin. The bottom of the pusher frame 20 has a pusher end 21. The sliding frame 23 establishes a movable connection with the pin through the slot. The upper left corner of the pusher frame 20 has an extension block. The sliding frame 23 establishes a connection with the extension block of the pusher frame 20 through the pin. When the pusher frame 20 is in a stationary state, there is a gap between the vertical rod of the pusher frame 20 and the right panel of the movable frame 23, which facilitates the pusher frame 20 to generate a small leftward turning displacement around the pin through the extension block. The top panel of the pusher frame 20 is impacted by the pressing end 19 and moves rapidly to the left around the pin. The bottom of the pusher frame 20 quickly pushes the workpiece into the workpiece chuck 28 through the pusher end 21, realizing the workpiece feeding process.

[0033] A fixing buckle is provided on the right end face of the sliding frame 23, directly opposite the pusher frame 20. A strong return spring 26 is provided on the fixing buckle. The right end face of the sliding frame 23 is connected to the pusher frame 20 at the opposite position through the fixing buckle and the strong return spring 26. That is, during the arc movement of the pusher frame 20 along the pin shaft, the sliding frame 23 is elastically protected by the strong return spring 26 to prevent it from moving to the left under force and colliding with the sliding frame 20. It can also provide elastic support when the pusher frame 20 rebounds under force through its own connection structure, ensuring that the pusher frame 20 can quickly return to its position and will not swing back and forth and collide with other structures.

[0034] The push port is designed as an arc-shaped frame with notches at both the left and right ends. That is, the left and right panels of the push port have large-area notches, so that the two sets of notches, together with the cavity, form an arc-shaped through groove with a semi-circular bottom, which can just accommodate the workpiece placed horizontally, and facilitate the push end 21 to push it directly into the workpiece clamp 28.

[0035] A horizontal mounting plate 2 is provided on the bottom left side of the vertical mounting frame 5. A horizontal ridge 3 is provided on the horizontal mounting plate 2. The right end of the horizontal ridge 3 extends into the vertical mounting frame 5. An auxiliary fixing seat 1 is fixed on the left end of the horizontal ridge 3. A limiting frame 4 is provided at the bottom front end of the auxiliary fixing seat 1. The bottom of the vertical mounting frame 5 is connected to the mounting housing of the rotating device through the horizontal mounting plate 2 and the horizontal ridge 3. The auxiliary fixing seat 1 is fixed by the rotating device. Then the limiting frame 4 is connected into the mounting housing to establish the stability of the vertical mounting frame 5 and the feeding device connected to it by the rotating device. This realizes the integrated setting of the feeding device, the workpiece chuck 28 and the grinding device, which can perform feeding and grinding of the workpiece in real time.

[0036] A workpiece chuck 28 is provided on the left side of the guide tube 24. The workpiece chuck 28 is set on the working chamber 27. The working chamber 27 is set to align the workpiece chuck 28, so that the feeding device can directly push the workpiece into the workpiece chuck 28 to realize the feeding process.

[0037] The ceramic internal grinding feeding device provided by this utility model is configured such that the entire feeding device is mounted on a rotating device. During the lifting and adjusting of the feeding device, two relative movements can be established with respect to the workpiece chuck 28: one opposite to the other and the other close to it. This facilitates feeding the empty workpiece chuck 28. After the feeding operation is completed, the entire feeding device moves upward, exposing the workpiece chuck 28 and the workpiece to be ground, which are horizontally aligned and facilitate the grinding device to grind the workpiece. The feeding device uses a servo motor 8 to drive the rotating screw 9 to rotate at a certain angle, adjusting the distance between the moving frame 7 and the lifting adjustment plate 10. This causes the sliding frame 23 to move up and down within the mounting frame 22, changing the positional relationship between the guide tube 24 and the workpiece chuck 28, thus facilitating the alternating control of repeated feeding and grinding.

[0038] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
