Description

Technical Field

[0001] The invention relates to the technical field of edge grinding machines, in particular to an elastic pressure type glass edge grinding machine. Background Art

[0002] Glass edge grinding machine is one of the earliest and most widely used mechanical equipment in glass deep processing equipment. Its main function is to grind glass and make some special shapes. The correct and reasonable use of edge grinding machine can not only ensure the normal production, but also extend the life of the machine. It is divided into single-arm special-shaped edge grinding machine, linear edge grinding machine and template edge grinding machine. The existing glass edge grinding machine cannot push the glass tightly. When people use the glass edge grinding machine, they cannot grind the glass of different widths and cannot adjust the width of different glass conveying. It is easy to cause the glass to loosen and deviate, resulting in uneven edge grinding and affecting the edge grinding quality.

[0003] To this end, a Chinese patent with publication number "CN219094615U" has published a "single-sided glass edge grinding machine", the main structure of which includes a workbench, a first concave seat is fixedly connected to the right side of the top of the workbench, a cylinder is fixedly connected to the left side of the inner cavity of the workbench, a push rod is fixedly connected to the right side of the cylinder, a moving block is fixedly connected to the right side of the push rod, a moving column is fixedly connected to the top of the moving block, and the top of the moving column penetrates the top of the workbench and is fixedly connected to the second concave seat. In this single-sided glass edge grinding machine, when adjusting the conveying position, the cylinder drives the push rod to start moving, the push rod drives the moving block to start moving, the moving block drives the sliding sleeve to slide on the sliding rod, and at the same time the moving block drives the moving column to start moving, and the moving column drives the second concave seat to start moving, so that the second concave seat moves to the specified position, and at this time the baffle presses the glass on the guide wheel tightly.

[0004] However, it is obvious that the above-mentioned single-sided glass edge grinding machine is huge in size and heavy in weight, and needs to be placed at a fixed point on the ground. At this time, it will lead to low flexibility in use. In addition, the grinding head and the side of the glass are in hard contact, which will result in the two being able to only provide hard contact grinding pressure during grinding. The hard contact grinding pressure has strict requirements on the mechanical motion stroke, which can easily lead to unstable grinding pressure and grinding loss, and poor working stability.

The surface of the glass is pressed against the force plate 115, and tension and pressure are reciprocatedly applied to the force plate 115, so that the piston plate 113 moves reciprocatingly inside the gas drive chamber 15. Since the air inlet end of the No. 1 gas one-way valve 18 is located in the direction close to the adsorption chamber 12, and the exhaust end is located in the direction close to the gas reserved chamber 14, and the air inlet end of the No. 2 gas one-way valve 19 is located in the direction close to the gas reserved chamber 14, and the exhaust end is located in the direction close to the external space, the gas inside the adsorption chamber 12 will be continuously extracted, and finally the suction cup shell 11 will be adsorbed on the surface of the glass, so as to realize the positioning and fixation of the equipment.

The structural radius of the gas reserve chamber 14 is smaller than the structural radius of the gas driving chamber 15, and the structural radius of the gas driving chamber 15 matches the structural radius of the piston plate 113.

[0031] To provide a cushioning effect between the grinding head and the glass side, thereby reducing the risk of glass damage due to hard contact grinding, please refer to Figure 1 , Figure 2 and Figure 5 , it is necessary to set up an elastic telescopic pressure-applying mechanism 2, inside which is provided a horizontal hollow shell 22 installed on the periphery of the suction cup shell 11 through a bearing and capable of rotating around the suction cup shell 11, a horizontal movable rod 26 placed inside the horizontal hollow shell 22 and capable of axially moving along the horizontal hollow shell 22, and when the horizontal movable rod 26 is extended and drives the drive motor 4 to move, a coil spring 27 that produces an elastic damping effect on the horizontal movable rod 26 and the drive motor 4, pulling the horizontal movable rod 26 to extend outward.

When the side of the grinding head 6 is located on one side of the side edge of the glass, the longitudinal height of the grinding head 6 is adjusted so that the side of the grinding head 6 can contact the side edge of the glass. At this time, the coil spring 27 is still in a compressed state. The elastic pressure will make the contact between the grinding head 6 and the side edge of the glass form a buffering effect, thereby reducing the occurrence of glass damage caused by hard contact grinding.

[0032] For the specific structure of the elastic telescopic pressure applying mechanism 2, please refer to Figure 5, including a horizontal hollow shell 22, one end of which is fixedly mounted with a No. 1 component collar 21, the annular hole of the No. 1 component collar 21 is fixedly mounted on the outer circumferential surface of the suction cup shell 11 through a bearing, a component movable cavity 23 is arranged inside the horizontal hollow shell 22, and a No. 2 rod body through-hole 24 connecting the external space and one end of the component movable cavity 23 is arranged at the other end of the horizontal hollow shell 22, and an inner movable plate 25 capable of axial movement along the component movable cavity 23 is arranged inside the component movable cavity 23 of the horizontal hollow shell 22, and one end surface of the inner movable plate 25 is fixedly mounted with a No. 2 rod body through-hole The horizontal movable rod 24 has a coil spring 27 in a compressed state sleeved on the outer periphery of the rod body located inside the component movable cavity 23, and a No. 2 component ring 28 is fixedly installed on one end of the horizontal movable rod 26 located outside the horizontal hollow shell 22, and the No. 2 component ring 28 is provided with a No. 1 annular embedding groove 29 of a concave structure in the middle of its ring hole, the structural shape of the cross section of the No. 2 rod body through-hole 24 is consistent with the structural shape of the cross section of the horizontal movable rod 26, both are polygonal structures, and the structural dimensions of the cross section of the No. 2 rod body through-hole 24 match the structural dimensions of the cross section of the horizontal movable rod 26.

[0033] In order to adjust the grinding position according to the specific height of the glass side, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , it is necessary to set up a longitudinal movable adjustment mechanism 3, which is internally provided with an outer brake rubber sleeve 34 fixedly embedded in the No. 1 annular embedding groove 29 and an inner brake rubber sleeve 33 placed at the center of the No. 1 annular embedding groove 29, and relying on the friction between the two, the drive motor 4 can be in a fixed state. A longitudinal force is manually applied to the longitudinal hollow shell 31. When the applied force is greater than the above-mentioned friction force, the longitudinal hollow shell 31 drives the drive motor 4 to achieve longitudinal height movement, thereby causing the grinding head 6 to change the grinding position.

[0034] For the specific structure of the longitudinal movable adjustment mechanism 3, please refer to Figure 6 and Figure 7, including a longitudinal hollow shell 31, an inner brake rubber sleeve 33 and an outer brake rubber sleeve 34, a motor fixing cavity 32 with open ends is arranged at the center of the longitudinal hollow shell 31, the drive motor 4 is fixedly installed inside the motor fixing cavity 32, and the rotor 5 is located directly below the motor fixing cavity 32, a second annular embedding groove 35 with an inner concave structure is arranged in the middle of the outer circumferential surface of the longitudinal hollow shell 31, an inner brake rubber sleeve 33 is embedded in the second annular embedding groove 35 of the longitudinal hollow shell 31, the outer brake rubber sleeve 34 is embedded in the first annular embedding groove 29, and the outer circumferential surface of the inner brake rubber sleeve 33 and the inner circumferential surface of the outer brake rubber sleeve 34 are in contact with each other, and the friction force between the inner brake rubber sleeve 33 and the outer brake rubber sleeve 34 at the contacting portion is sufficient to make the longitudinal hollow shell 31 in a stationary state during operation.

[0035] When in use, the suction cup shell 11 is moved to the central area of ​​a surface of the glass, and then the bottom of the rubber sealing gasket 13 is pressed against the surface of the glass, and tension and pressure are reciprocatingly applied to the force plate 115, so that the piston plate 113 moves back and forth inside the gas drive chamber 15, and the gas inside the adsorption chamber 12 is continuously extracted, and finally the suction cup shell 11 is adsorbed on the surface of the glass, pulling the horizontal movable rod 26 to extend outward.

When the side of the grinding head 6 is located on one side of the side of the glass, a longitudinal force is manually applied to the longitudinal hollow shell 31. When the applied force is greater than the above-mentioned friction force, the longitudinal hollow shell 31 drives the driving motor 4 to achieve longitudinal height movement, and then the grinding head 6 changes the grinding position, so that the side of the grinding head 6 can press against the side of the glass, start the driving motor 4, and the rotor 5 will drive the grinding head 6 to rotate rapidly. When the side of the grinding head 6 contacts the side of the glass, the side of the glass can be polished.
