Description

Technical Field

[0001] The utility model relates to the technical field of coaxiality control, in particular to a coupling fixing structure. Background Art

[0002] The shuttle is a specialized device used in the photovoltaic glass cold-end production line to transport cut glass sheets directly from the second floor to the first floor. It primarily consists of a sheet accumulator, conveyor, signal transmitter, and servo control system, with the belt conveyor assembly being a key component of the accumulator. With the rapid development of the photovoltaic glass industry, the requirements for the belt conveyor assembly, which serves as the glass conveyor, are becoming increasingly stringent, requiring it to accommodate wide sheets or even double sheets in parallel.

[0003] Normally, due to the large span, wide plate conveying or double-plate parallel conveying usually uses multiple sets of belts arranged in parallel, and a coupling is added to the output end of the reducer to connect it to the rear-end drive shaft to transmit power. When the coupling connects the reducer to the drive shaft, it has high requirements for the radial offset and angular offset of the reducer output shaft and the drive shaft, which are even more difficult for the coupling to guarantee. During assembly, when the radial offset and angular offset of the reducer output shaft and the drive shaft are greater than the radial and angular correction capabilities of the coupling itself, the life of the coupling or its locking screws will be shortened. At present, some assembly detection methods for the coaxiality of the reducer and drive shaft connection are to detect with a dial indicator or measure with a spirit level. This assembly detection method is not only inefficient, but also cannot guarantee assembly accuracy. Utility Model Content

[0020] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described in conjunction with the accompanying drawings.

[0021] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0022] In this application, unless otherwise expressly specified or limited, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly indicate the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise expressly specified or limited.

[0023] See Figures 1 to 3 This embodiment discloses a coupling fixing structure, including a bracket 1 and a positioning shaft 2. The bracket 1 can be movably set on the shuttle body 3, and the bracket 1 is provided with a mounting hole 101 for mounting the coupling 6 and the positioning shaft 2.

[0024] In this embodiment, the bracket 1 is L-shaped, the horizontal section is fixed on the shuttle body 3, and the mounting hole 101 is provided on the vertical section; further, a plurality of fixing holes are provided on the horizontal section of the bracket 1, and the bracket 1 is fixed to the shuttle body 3 by bolts 4 passing through the fixing holes. The diameter of the fixing hole is larger than the screw diameter of the bolt 4 and smaller than the diameter of the bolt head, so that the position of the bracket 1 can be adjusted on the shuttle body 3, which meets the position adjustment requirements when the coupling 6 is installed later.

[0025] The positioning shaft 2 includes a mounting seat 21, a sleeve 22, and a connecting shaft 23. The central axes of the mounting seat 21, sleeve 22, and connecting shaft 23 are the same central axis. The mounting seat 21 is cylindrical and stepped. The small end of the mounting seat 21 is mounted on the mounting hole 101 and passes through the mounting hole 101, and the large end is attached to the vertical section of the bracket 1. The sleeve 22 is connected to the small end of the mounting seat 21, and the connecting shaft 23 is connected to the large end of the mounting seat 21. The sleeve 22 is used to sleeve the transmission shaft 5. The clearance between the inner hole of the sleeve 22 and the transmission shaft 5 is 0.03 to 0.05 mm. The connecting shaft 23 is used to simulate the output shaft of the reducer 7.

[0026] A positioning hole 102 is also provided on the horizontal section of the bracket 1, and the coupling fixing structure also includes a positioning pin that can be inserted into the positioning hole 102; specifically, when the position of the bracket 1 is determined and fixed, a socket coaxial with the positioning hole 102 is provided on the shuttle body 3 through the positioning hole 102, and then the positioning pin is inserted into the positioning hole 102 and the socket to fix the position of the bracket 1 to prevent the bolt 4 from loosening and causing the bracket 1 to move.

[0027] The working principle of this embodiment is as follows: the horizontal section of the bracket 1 is roughly fixed to the shuttle body 3 by passing the bolt 4 through the fixing hole. At this time, the bolt 4 is not required to completely fix the bracket 1; then the small head end of the mounting seat 21 is installed on the mounting hole 101 and passes through the mounting hole 101, and the large head end is fitted on the vertical section of the bracket 1. At this time, the position of the bracket 1 on the shuttle body 3 is adjusted, and the shaft sleeve 22 can be sleeved on the transmission shaft 5. The coaxiality error between the mounting hole 101 and the transmission shaft 5 is the matching clearance between the positioning shaft 2, the bracket 1 and the transmission shaft, which fully meets the use requirements, that is, At this time, the installation position of the bracket 1 meets the coaxial installation requirements of the coupling 6, and then the bolt 4 is fully tightened to completely fix the bracket 1 on the shuttle body 3, and then a socket coaxial with the positioning hole 102 is opened on the shuttle body 3, and then the positioning pin is inserted into the positioning hole 102 and the socket to fix the position of the bracket 1 to prevent the bolt 4 from loosening and causing the bracket 1 to move. Then, take out the positioning shaft 2, put the coupling 6 on the output shaft of the reducer 7, and then install the reducer 7 through the bracket 1 and at the same time put the coupling 6 into the transmission shaft 5 to complete the installation of the coupling 6.

[0028] In this embodiment, the bracket and the positioning shaft 2 are matched to ensure the coaxiality of the coupling 6 and the transmission shaft 5 , thereby improving the assembly accuracy and efficiency of the coupling 6 and the transmission shaft 5 .
