[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The present application embodiment discloses a fully automatic chamfering machine for the inner hole of a ceramic cylinder, referring to Figure 1 , including a frame 1, a turntable 2 is intermittently rotated at the bottom of the frame 1, and the bottom of the turntable 2 has a rotating shaft, and the turntable 2 is horizontally rotatably connected to the bottom of the frame 1 through the rotating shaft. At the same time, the turntable 2 is evenly spaced around the central axis and is used to vertically fix ceramic products. In this embodiment, the number of the fixing mechanisms 3 is set to eight, and a chamfering device 4 is set at the top of the frame 1. The ceramic products fixed in each of the eight fixing mechanisms 3 can be moved to the chamfering position of the chamfering device 4 as the turntable 2 rotates, so that the chamfering device 4 can chamfer the ceramic products moved to the chamfering position. A control mechanism 5 for controlling the rotation angle of the turntable 2 is also provided at the bottom of the frame 1. In this embodiment, the control mechanism 5 controls the rotation angle of the turntable 2 to be set to 45° each time. Whenever the turntable 2 stops rotating, a ceramic product fixed in a fixing mechanism 3 is located at the chamfering position of the chamfering device 4. When a ceramic product in a fixing mechanism 3 is undergoing a chamfering operation at a chamfering position, loading and unloading operations can be performed on ceramic products that are not at the chamfering position, so that the chamfering operation and the loading and unloading operations of the ceramic products can be performed simultaneously. The chamfering device 4 does not need to stop working, which is convenient and quick, and is beneficial to improving the chamfering efficiency of the inner holes of ceramic products, thereby helping to improve the production capacity of ceramic products.

[0037] Reference Figure 1 and Figure 2Each fixing mechanism 3 includes a placement seat 31 and a clamping member. The placement seat 31 is rotatably connected to the upper surface of the turntable 2 for vertically placing and positioning ceramic products. The clamping member is arranged on the placement seat 31 for fixing the ceramic products. In this embodiment, the clamping member is selected as a clamping cylinder, which clamps and fixes the vertically placed ceramic products to improve the stability of the chamfering operation.

[0038] Reference Figure 3 and Figure 4 The control mechanism 5 includes a matching rotation drive component 51 and a stop component 52. The rotation drive component 51 is arranged at the bottom of the frame 1 to drive the turntable 2 to rotate a set rotation angle. In this embodiment, the turntable 2 rotates at a set rotation angle of 45° each time. After the turntable 2 rotates 45°, the stop component 52 is located on one side of the turntable 2 and is used to fix the turntable 2 to improve the chamfering stability and accuracy of the chamfering device 4 on the ceramic products located at the chamfering position.

[0039] Reference Figure 3 and Figure 4 The rotation driving assembly 51 includes a lever 511, a moving block 512 and a first driving member. The moving block 512 is horizontally slidably connected to the bottom of the frame 1. The first driving member is arranged at the bottom of the frame 1 to drive the moving block 512 to reciprocate in the horizontal direction toward or away from the turntable 2. In this embodiment, the first driving member is arranged to be a first driving cylinder 513. The moving block 512 is fixedly connected to the end of the piston rod of the first driving cylinder 513. The lever 511 is elastically telescopically connected to the side wall of the moving block 512 toward the turntable 2, and the lever 511 is against the side wall of the turntable 2. The lever 511 is elastically telescopically connected to the moving block 512 through a spring structure, which will not be repeated here. The piston rod of the first driving cylinder 513 is in an initial state when in a contracted state. As the piston rod of the first driving cylinder 513 is stretched to push the moving block 512 and the lever 511 toward the direction close to the turntable 2, the lever 511 abuts against the rotating shaft of the turntable 2 and drives the turntable 2 to rotate. The elastic telescopic setting of the lever 511 will not hinder the movement of the lever 511. The turntable 2 is driven to rotate by driving the movement, and the rotation angle of the drive turntable 2 can be controlled by controlling the moving distance of the driving moving block 512, so as to improve the accuracy and stability of controlling the rotation angle of the turntable 2.

[0040] Reference Figure 3 and Figure 4 A guide rail 10 is also fixedly disposed horizontally on the side wall at the bottom of the frame 1, and the moving block 512 is sleeved and slidably disposed on the guide rail 10 to improve the stability of the moving block 512 when moving, thereby improving the stability of the lever 511 when pushing the turntable 2 to rotate.

[0041] Reference Figure 3 and Figure 4, when the turntable 2 rotates 45° under the drive of the rotation drive assembly 51, the stop assembly 52 fixes the turntable 2. Specifically, the stop assembly 52 includes a stop block 521 and a second driving member. The stop block 521 is located at one side of the turntable 2. The second driving member is arranged on the frame 1 to drive the stop block 521 to reciprocate in the direction close to or away from the turntable 2. At the same time, a plurality of stop grooves 6 for the stop block 521 to be embedded in the edge of the turntable 2 are provided. In this embodiment, the second driving member is set as a second driving cylinder 522, and the stop block 521 is fixedly connected to the piston rod of the second driving cylinder 522. The number of the stop grooves 6 is the same as the number of the fixing mechanism 3, which is set to eight, and the eight stop grooves 6 are evenly spaced along the circumference of the turntable 2. The cross section of the stop block 521 is set in an isosceles triangle. When the stop block 521 is embedded in the stop groove 6, the two isosceles sides of the stop block 521 are pressed against the two groove walls of the stop groove 6 to improve the stability of the turntable 2 when it is stationary.

[0042] Reference Figure 4 When the stopper assembly 52 fixes the turntable 2, the ceramic product on a fixing mechanism 3 on the turntable 2 stays at the chamfering position of the chamfering device 4. At this time, the chamfering device 4 performs a chamfering operation on the ceramic product. Figure 1 The chamfering device 4 includes a support platform 41, a mounting seat 42, a grinding head 43, a third driving member and a fourth driving member. The third driving member is arranged on the top of the frame 1 to drive the support platform 41 to move vertically up and down. The mounting seat 42 is arranged on the support platform 41. The grinding head 43 is detachably connected to the bottom of the mounting seat 42. The detachable connection structure of the grinding head 43 is a conventional setting for connecting the grinding head 43 with the mounting seat 42, which will not be described in detail here. The fourth driving member is arranged on the top of the mounting seat 42 to drive the grinding head 43 to rotate at a high speed. In this embodiment, the third driving member is set as a third driving cylinder 44, the piston rod of the third driving cylinder 44 is fixedly connected to the support platform 41, and the fourth driving member is set as a driving motor 45. The driving motor 45 is installed on the mounting seat 42 to drive the grinding head 43 connected to the mounting seat 42 to rotate at a high speed.

[0043] It should be noted that the process of the third driving cylinder 44 driving the support platform 41 to move vertically downward is divided into two stages. The first stage is that the third driving cylinder 44 drives the support platform 41 to quickly descend to a position close to the ceramic product, and the second stage is that the third driving cylinder 44 drives the support platform 41 to slowly descend so that the grinding head 43 contacts the ceramic product and then performs the chamfering operation. The rotation direction of the grinding head 43 is opposite to the rotation direction of the placement seat 31, so that the grinding head 43 can chamfer the ceramic product.

[0044] Reference Figure 1 Two guide rods 7 are vertically fixed on the frame 1, and the support platform 41 is movably sleeved on the two guide rods 7 to improve the stability of the support platform 41 when it moves vertically up and down.

[0045] Reference Figure 5 and Figure 6 The support platform 41 includes a connecting plate 411, a supporting plate 412 and a fixing member 413. The supporting plate 412 and the connecting plate 411 are arranged to overlap in a horizontal state, and the overlapping position of the supporting plate 412 and the connecting plate 411 is adjustable to fine-tune the chamfer position of the grinding head 43. The fixing member 413 is used to fix the supporting plate 412 and the connecting plate 411. Specifically, the support plate 412 is provided with a first waist-shaped hole 8, and the connecting plate 411 is provided with a second waist-shaped hole 9. The length direction of the first waist-shaped hole 8 is perpendicular to the length direction of the second waist-shaped hole 9. The fixing member 413 is configured as a matching bolt 4131 and a nut 4132. The bolt 4131 is movably inserted into the support plate 412 through the first waist-shaped hole 8, and the bolt 4131 passes through the support plate 412 and then passes through the second waist-shaped hole 9 and is movably inserted into the connecting plate 411. The nut 4132 is threadedly sleeved on the end of the bolt 4131 passing through the support plate 412 and the connecting plate 411 to realize the connection between the support plate 412 and the connecting plate 411. When it is necessary to fine-tune the chamfer position of the grinding head 43, the staff loosens the bolt 4131 and the nut 4132, and the overlapping position of the support plate 412 and the connecting plate 411 can be adjusted. The setting of the first waist-shaped hole 8 and the second waist-shaped hole 9 makes way for the movement of the bolt 4131, so that the adjustment action of the support plate 412 and the connecting plate 411 can be carried out smoothly.

[0046] Reference Figure 1 A manipulator 11 is also provided on one side of the frame 1. The manipulator 11 automatically loads and unloads ceramic products through a set action program to save labor and realize a fully automatic process of chamfering ceramic products.

[0047] The implementation principle of the fully automatic chamfering machine for the inner hole of a ceramic cylinder in the embodiment of the present application is as follows: when the inner hole of the cylinder needs to be chamfered on a ceramic product, the manipulator 11 places the ceramic product vertically on the placement seat 31, the clamping cylinder 32 clamps and fixes the ceramic product, and then the first driving cylinder 513 pushes the moving block 512 and the lever 511 to move, and the lever 511 moves to drive the turntable 2 to rotate 45° so that the fixed ceramic product moves to the chamfering position, and the second driving cylinder 522 pushes the stop block 521 to embed into the stop groove 6, and then the grinding head 43 The ceramic products are chamfered under the driving movement of the third driving cylinder 44 and the driving rotation of the driving motor 45. The above actions can be repeated to realize the fully automatic chamfering process of the ceramic products. In the process of the chamfering device 4 chamfering the ceramic products, the ceramic products that are not in the chamfering position can be loaded and unloaded, so that the chamfering operation and the loading and unloading operations of the ceramic products are carried out simultaneously. The chamfering device 4 does not need to stop working, which is convenient and quick, which is beneficial to improving the chamfering efficiency of the inner holes of ceramic products, thereby helping to improve the production capacity of ceramic products.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
