Description

Technical Field

[0001] The utility model belongs to the technical field of automatic equipment accessories, and in particular relates to a double centering structure of a glass edge grinding machine. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added. It is widely used in buildings to block wind and transmit light. It is a mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called organic glass;

[0003] In the process of glass production, one of the steps is to grind the edge of the glass, which requires the use of a glass edge grinding machine;

[0004] At present, when glass is being polished, it needs to be moved to a conveying mechanism. For the placement of small glass, manual placement and the use of suction cups and robots for clamping and moving are commonly used. However, these two methods are not suitable for large glass, because large glass cannot be lifted horizontally by one person, and if it is lifted by two or more people, there is a possibility that the center of the glass will fall and break. Therefore, mechanical equipment is often used for transfer or loading of large glass;

[0005] However, there is a problem at present. After the glass is loaded, how to center the supporting object, that is, to support it evenly on the lower side of the glass so that the glass will not fall or bend. If the specifications of the glass are consistent, it can be supported at a fixed point. However, when the specifications of the glass change, how to adaptively and quickly change the position of the support is a problem that needs to be considered at present. Utility Model Content

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1 to Figure 4 As shown, the double centering structure of the glass edge grinding machine of the utility model comprises a base frame 1, the base frame 1 is in a square shape, power transfer mechanisms 2 are symmetrically installed on the sides of the base frame 1, a power mechanism 3 is installed between the two power transfer mechanisms 2 on the base frame 1, an outer limit mechanism 4 and an inner bearing mechanism 5 are installed on the upper side of the base frame 1, and the outer limit mechanism 4 is located outside the inner bearing mechanism 5;

[0034] The power transfer mechanism 2 includes a first driven pulley 21, a second driven pulley 22 and a first turbine box 23 installed on the chassis 1. The output end of the first turbine box 23 is installed with a first synchronous wheel 24 and a second synchronous wheel 25. The first synchronous wheel 24 is coaxial with the second synchronous wheel 25. The first synchronous wheel 24 and the second synchronous wheel 25 have different diameters. A first belt 26 is connected between the first synchronous wheel 24 and the first driven pulley 21, and a second belt 27 is connected between the second synchronous wheel 25 and the second driven pulley 22. A driven sprocket 28 is installed at the input end of the first turbine box 23.

[0035] The power mechanism 3 includes a motor 31 and two second turbine boxes 32 mounted on the chassis 1. A connecting rod 33 is connected between the two second turbine boxes 32. The two second turbine boxes 32 move synchronously through the connecting rod 33. The motor 31 is connected to the input end of one of the second turbine boxes 32. The output ends of the two second turbine boxes 32 are both equipped with driving sprockets 34. The driving sprocket 34 is connected to the driven sprocket 28 by chain transmission.

[0036] The external limit mechanism 4 includes two screw rods 41 rotatably mounted on the base frame 1, the two screw rods 41 are installed in parallel, the two screw rods 41 are respectively fixedly connected to the axial rod of the driving sprocket 34, the two screw rods 41 have the same rotation direction, and the two screw rods 41 are threadedly connected with a moving block 42. The external limit mechanism 4 includes a fixed block 43 fixedly mounted on the base frame 1, the fixed block 43 and the moving block 42 are installed in parallel and symmetrically, and the fixed block 43 and the screw rod 41 do not interfere with each other;

[0037] The internal load-bearing mechanism 5 includes two groups of supports 51 and two slide rails 52. The two groups of supports 51 are slidably installed on the slide rails 52. One group of supports 51 is fixedly installed on the first belt 26, and the other group of supports 51 is fixedly installed on the second belt 27. The supports 51 are installed with displacement bars 53. The upper side of the displacement bars 53 is installed with support rods 54, and the support rods 54 are connected to support bars 55.

[0038] In this embodiment, when the double centering structure of the glass edge grinding machine is used, the starting motor 31 drives the second turbine box 32 to rotate. Under the effect of the connecting rod 33, the two second turbine boxes 32 operate synchronously. The operation of the second turbine box 32 causes the screw rod 41 to rotate. The rotation of the screw rod 41 causes the moving block 42 threadedly connected to the screw rod 41 to move, thereby achieving the purpose of adjusting the distance between the moving block 42 and the fixed block 43, thereby adapting to the placement of glass of different specifications.

[0039] When the screw rod 41 rotates, the driving sprocket 34 drives the driven sprocket 28 to rotate, thereby making the first turbine box 23 run, and the first synchronous wheel 24 and the second synchronous wheel 25 run and run synchronously, that is, the screw rod 41 and the first synchronous wheel 24 and the second synchronous wheel 25 run synchronously, and the rotation of the first synchronous wheel 24 cooperates with the first driven pulley 21 to realize the rotation of the first belt 26, and the rotation of the first belt 26 causes the support 51 installed on the first belt 26 to move, and the corresponding support bar 55 moves. Similarly, the rotation of the second synchronous wheel 24 cooperates with the second driven pulley 22 to realize the rotation of the second belt 27, and the rotation of the second belt 27 causes the support 51 installed on the second belt 27 to move, and the corresponding support bar 55 moves.

[0040] In summary, when the moving block 42 moves, the corresponding two support bars 55 also move to achieve the purpose of centering, ensuring equidistant support on the lower side of the glass, preventing the glass from falling and bending, and the debugging and coordination effect is good, and the bottom support position of the glass of the corresponding specifications can be quickly determined. Furthermore, benefiting from this structure, by adjusting the diameter size of the first synchronous wheel 24 and the second synchronous wheel 25, the position of the two support bars 55 on the lower side of the glass can be controlled, thereby expanding the adaptability.

[0041] Preferably, the base frame 1 is installed with a fixing plate 29, and the fixing plate 29 is provided with a waist-shaped hole 210. The first driven pulley 21 and the second driven pulley 22 are both installed in the waist-shaped hole 210. Such a design allows for fine-tuning of the installation positions of the first driven pulley 21 and the second driven pulley 22, thereby ensuring smooth installation of the first belt 26 and the second belt 26, and achieving tension adjustment of the first belt 26 and the second belt 26. In fact, the installation method of the first driven pulley 21 and the second driven pulley 22 can also be considered according to specific circumstances.

[0042] Preferably, the contact surface between the fixed block 43 and the movable block 42 is horizontally polished. Such a design ensures the contact effect with the edge of the glass and prevents the glass from tilting after being clamped or placed. In fact, the treatment measures for the contact surface can also be considered according to the specific situation.

[0043] Preferably, the support rod 54 is a height-adjustable support rod. Such a design can adjust the placement height of the glass. In fact, the selection of the support rod 54 can also be considered according to specific circumstances.
