DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, a device for grinding the inner edge of a glass product provided by an embodiment of the present invention comprises: A bottom plate 1, the bottom plate 1 is fixedly connected to a top plate 3 via a support 2, a plane translation mechanism 4 is provided on the top plate 3, a connecting seat 5 is installed on the plane translation mechanism 4, and a grinding mechanism is installed on the connecting seat via a lifting component; The grinding mechanism is connected with a mounting seat 15, a plurality of supporting arms 14 are rotatably connected to the mounting seat 15, an anti-sliding block 6 is rotatably connected to the supporting arms 14, a plurality of rebound grooves 34 are arranged inside the anti-sliding block 6, a supporting block 36 is connected to the bottom of the anti-sliding block 6, and a supporting beam 35 is arranged inside the anti-sliding block 6; The grinding mechanism is connected to the mounting seat 15 via a pressure sensor. When the grinding mechanism descends, the inner diameter of the workpiece is calculated based on the data detected by the pressure sensor, and the grinding mechanism is controlled to perform inner grinding according to the inner diameter. An image acquisition device is fixedly mounted on the connection base 5 .

[0018] In the embodiment of the present invention, when grinding, the workpiece is placed on the bottom plate 1, and the workpiece below can be automatically identified by the image acquisition device. The workpiece is a glass product, a cylindrical container with a large diameter, and the workpiece can be colored glass or transparent glass. When the image acquisition device determines that there is a workpiece, it moves to the position of the corresponding workpiece. After determining the position of the workpiece, the grinding device is controlled to move above the workpiece to be ground. The lifting component drives the grinding mechanism to move downward. In this process, the data of the pressure sensor is recorded to construct a two-dimensional coordinate system. The horizontal coordinate of the two-dimensional coordinate system is the distance the grinding mechanism moves downward, and the vertical coordinate is the vertical coordinate. is the pressure value detected by the pressure sensor, and a pressure value curve is constructed in the two-dimensional coordinate system. During the descent of the grinding mechanism, the support block 36 gradually approaches the bottom of the inner cavity of the workpiece. When the support block 36 contacts the bottom of the inner cavity of the workpiece, since there is a certain initial angle between the support arm 14 and the horizontal plane, the support block 36 will slide relative to the workpiece during the downward movement of the grinding mechanism, and the angle between the support arm 14 and the bottom plate 1 gradually increases until the anti-sliding block 6 abuts against the inner wall of the workpiece. As the grinding mechanism moves further downward, the angle between the support arm 14 and the bottom plate 1 reaches the maximum, and the workpiece is fixed. When the workpiece is in position When the workpiece is offset, the workpiece can be automatically aligned by synchronously extending multiple groups of support blocks 36. There are three groups of support blocks 36. During the descent of the grinding mechanism, the change of the pressure value curve is mainly divided into three stages. In the first stage, the support block 36 is not in contact with the workpiece. At this time, the value of the pressure sensor is 0 or the initial value. In the second stage, when the support block 36 begins to contact the bottom of the workpiece and slides along the bottom of the workpiece, due to the reaction force of the workpiece on the support block 36, the value of the pressure sensor will increase to a certain value and fluctuate within this range. In the third stage, the anti-sliding block 6 contacts the inner wall of the workpiece. The displacement of the support block 36 will be restricted, and the value of the pressure sensor will increase rapidly. Therefore, when the curvature of the pressure value curve is greater than the preset value, it is determined that the workpiece has been clamped. The turning point between the first stage and the second stage is the first turning point, and the turning point between the second stage and the third stage is the second turning point. Then the horizontal coordinate difference between the first turning point and the second turning point is the distance moved by the grinding mechanism during the time period when the support block 36 contacts the workpiece and the workpiece is fixed. Since the length of the support arm 14 is known, the inner diameter of the workpiece can be calculated, and the grinding mechanism grinds the inner opening of the workpiece according to the inner diameter of the workpiece.

The sliding sleeve is also provided with a third sliding sleeve 33, the inner cavity cross section of the third sliding sleeve 33 is rectangular, the two sides of the third sliding sleeve 33 are rotatably connected with the first lifting sleeve 21 and the second lifting sleeve 28 respectively, the third sliding sleeve 33 is rotatably connected with the third gear 26, and the third gear 26 is meshed with the first end gear 25 and the second end gear 27 at the same time, and the end of the second lifting sleeve 28 away from the first lifting sleeve 21 is rotatably connected with a magnetic ring through a bearing 32, and an electromagnet 16 is fixedly provided at a position between the mounting seat 15 and the second lifting sleeve 28 on the square shaft 13. The first lifting sleeve 21 is fixedly connected to the second gear 20 at one end away from the second lifting sleeve 28, and the second gear 20 is meshed with the first gear 12. The first lifting sleeve 21 and the second lifting sleeve 28 are both fixedly installed with multiple groups of telescopic sleeves 18. The sliding sleeve inside the telescopic sleeve 18 is provided with a telescopic rod 19, and a micro motor is fixedly installed on the telescopic sleeve 18. A driving screw is fixedly connected to the output shaft of the micro motor, and a threaded hole is provided on the telescopic rod 19. The telescopic rod 19 is connected to the driving screw through the threaded hole, and a grinding block 17 is fixedly provided on the telescopic rod 19.

[0022] In this embodiment, after the inner diameter of the workpiece is determined, the micro motor is started, and the telescopic rod 19 is driven to extend by the micro motor. The telescopic rod 19 will extend along the telescopic sleeve 18. The telescopic rod 19 and the telescopic sleeve 18 are respectively provided with guide blocks and guide grooves for limiting the rotation of the telescopic rod 19. The telescopic rod 19 will drive the grinding block 17 to move, thereby changing the extended length of the grinding block 17. Multiple groups of grinding blocks 17 are evenly arranged, and then the second motor 11 is started, and the first gear 12 is driven to rotate by the second motor. The first gear 12 will drive the second gear 20 to rotate, and the second gear 20 will drive the first lifting sleeve 21 to rotate. The first lifting sleeve 21 will rotate relative to the first sliding sleeve 23. The first sliding sleeve 23 can only slide up and down along the square shaft 13 and cannot rotate. The first sliding sleeve 23 is connected to the power connecting groove through the power connecting slider, so as to obtain electric energy and supply power to the first coil 22. The first coil 22 supplies energy to the second coil 24, and the second coil 24 is connected to the micro motor. At the same time, the first end gear 25 drives the second end gear 27 to rotate through the third gear 26, and the second end gear 27 drives the second lifting sleeve 28 to rotate. Due to the existence of the third gear 26, the first lifting sleeve 21 and the second lifting sleeve 28 will rotate in opposite directions, so the grinding blocks 17 located on the first lifting sleeve 21 and the second lifting sleeve 28 will also grind in opposite directions. Since the grinding directions are opposite, the torques applied to the workpiece by the grinding blocks 17 of the two rotation directions will be offset, thereby avoiding the rotation of the workpiece. Therefore, when clamping the workpiece, a smaller clamping force can be used. Therefore, when grinding thin-walled workpieces, excessive clamping force can be avoided to cause damage to the workpiece; when the grinding axis position needs to be adjusted, the electromagnet 16 is controlled to be energized, and the repulsive force between the electromagnet 16 and the magnetic ring is controlled by changing the magnetic field strength of the electromagnet 16 to change the height of the grinding position. In order to achieve stable control of the grinding height, the magnetic ring and the electromagnet 16 are connected by a spring.

[0026] In this embodiment, when it is determined that the workpiece has been clamped, if the pressure value of the pressure sensor reaches a preset value, it is determined that the workpiece has been clamped. At this time, the locking assembly limits the support arm 14. The locking assembly can be a miniature telescopic rod. After clamping, the miniature telescopic rod extends to hold the support arm 14. The locking assembly is used to limit the rotation of the support arm 14, and the specific structure is not limited.

[0027] like Figure 1 As shown, as a preferred embodiment of the present invention, a loading area and a unloading area are provided on the bottom plate 1, and the unloading area includes unloading partitions of multiple sizes.

After the workpiece is clamped, the locking assembly locks the support arm 14, and the lifting assembly drives the grinding mechanism to rise, so that the workpiece will also be lifted. In this process, the inner mouth of the workpiece is grinded by the grinding block 17. After grinding is completed, it will be placed on the unloading conveyor belt corresponding to the different unloading partitions according to its size, or the corresponding storage area. Grinding can start after clamping is completed, which reduces the time interval for grinding and improves the grinding efficiency.
