Description

Tool structure for mounting external roller Technical Field The utility model belongs to the technical field of tooling structures, and relates to a tooling structure for mounting an external roller. Background The external roller is usually an external electric roller, and is used as a novel driving device for installing a motor outside a roller body, wherein a speed reducing device is arranged inside the electric roller, the working principle of the external roller is that the motor runs outside the roller, and power generated by an output shaft of the motor is transmitted through a coupler (or coupler) to enter the inside of the electric roller, and then the motor drives the roller body to rotate through a speed reducing mechanism, so that a conveying belt is driven to rotate. In the prior art, the motor output shaft is connected with the electric roller through a flange plate, and in order to realize the installation of the motor, a base is usually arranged at one end of the electric roller to install the motor, so that the connection between the motor output shaft and the electric roller is realized. The external roller is widely applied in various industrial fields by virtue of the unique design structure and excellent performance. However, although the external roller has many advantages, such as high transmission efficiency and compact structure, there are many problems to be solved in terms of installation and maintenance in the practical application process. First, space limitations are a major challenge in the installation of outboard rollers. This places a higher demand on the installation space, since the motor is installed outside the drum. In many industrial sites or bench test environments, the connection of the motor to the drum is often difficult to access due to limited space, which presents a great inconvenience for maintenance work. When maintenance personnel perform routine inspection or fault maintenance, more time and effort are required to overcome the space limitation, which not only increases the difficulty of maintenance, but also increases the maintenance cost in an intangible way. Secondly, the inconvenience of the motor disassembly of the external drum is also a significant drawback in its installation structure. The motor and the drum are usually connected by complex connection and fixing structures, and the structures tend to be more focused on the stability of connection in design, and neglect the convenience of disassembly. When maintenance or replacement of the motor is required, the disassembly process can become extremely cumbersome, even requiring the use of special tools or equipment. This not only extends maintenance time, but may also potentially damage other parts of the apparatus. In addition, the motor installation of the external drum may also cause an increase in initial investment costs. In order to ensure that the motor can be stably and reliably mounted outside the drum, it may be necessary to employ a more complicated mounting structure (such as a base separately arranged for mounting the motor) and a more advanced motor model. These additional designs and materials of choice certainly increase the manufacturing costs of the equipment, which in turn increases the initial investment of the whole project. In view of the above, there are still many issues to be solved in terms of installation and maintenance of the external roller. Therefore, it is necessary to provide a novel tooling structure for installing an external roller, so as to solve the problems of space limitation, inconvenient disassembly, high initial investment cost and the like in the prior art. Disclosure of utility model In view of the above, the present utility model is directed to a tooling structure for mounting an external roller, so as to mount a motor in the external roller without using a base. In order to achieve the above purpose, the present utility model provides the following technical solutions: The tool structure for mounting the external roller comprises fixing seats arranged at two ends of the roller, and the roller is rotationally connected with the fixing seats; Also comprises a fixed end fixedly connected with one of the fixed seats, one side of the fixed end, which is far away from the roller, is connected with a motor bottom plate, and the motor bottom plate is used for installing a motor; a pull rod is arranged between the motor bottom plate and the fixed end, one end of the pull rod is connected with one end, far away from the fixed end, of the motor bottom plate, and the other end of the pull rod is connected with the top of the fixed end, so that a diagonal structure is formed. Further, a pressing plate is arranged on the motor bottom plate and used for fixing the motor on the motor bottom plate. Further, the number of the pressing plates is at least 4, the four corners of the motor are respectively pressed, at least two bolt holes are formed in each pressing plate, a
