At the same time, a fixing device is provided on the bearing press, and this fixing device is used to fix the motor to be installed to keep it stable during the press-fitting process.

[0003] For example, the utility model patent with the publication number CN219633165U specifically discloses a valve body processing and positioning device, which realizes the single-person operation of the valve body processing and positioning device and does not require multiple operations to fix the valve body by rotating the handle, fixed block, bidirectional screw, sliding block, connecting plate, fixed plate, and arc-shaped fixed plate.

[0004] In the above-mentioned disclosed patent, the device fixes the workpiece by setting two groups of arc-shaped fixed plates. However, since this arc-shaped fixed plate can only move unidirectionally, the size of the motor that can be fixed is relatively limited. When the size of the workpiece is smaller than the size of the arc-shaped fixed plate, the fixation may not be firm enough, and when the size of the workpiece is larger than the arc-shaped fixed plate, the workpiece may not be able to be installed between the two groups of arc-shaped fixed plates. This results in low flexibility of the device and may affect the working efficiency of the device. Therefore, it is necessary to provide a bearing press-fitting and fixing tooling with an adjustable fixing device to solve the above problems.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] As Figure 1 - Figure 2 shown, the present application provides a bearing pressing and fixing tooling, including a pressing machine 1, which is arranged in a processing workshop. The pressing machine 1 includes an installation platform 2, and a fixing device 3 is arranged on the installation platform 2. The fixing device 3 is used to fix the motor to be pressed. At the same time, a pressing assembly 4 is arranged on the top of the fixing device 3, and the pressing assembly 4 is used to perform a pressing operation on the bearing of the motor in the fixing device 3.

[0025] The pressing assembly 4 includes a first cylinder 41. At the same time, a pressing plate 42 is fixedly arranged at the output end of the first cylinder 41. At the same time, a pressing head 43 is arranged in the pressing plate 42, and the pressing head 43 is adapted to the size of the bearing. When the device works, the first cylinder 41 drives the pressing head 43 to move towards the fixing device 3, and then the pressing head 43 contacts the bearing and presses the bearing into the motor, thereby realizing the pressing operation of the motor.

[0026] As Figure 2 - Figure 3As shown in the figure, in order to prevent the motor from shifting when it comes into contact with the press-fitting assembly 4, the fixing device 3 is arranged below the pressing head 43 to fix the motor to be processed. The fixing device 3 includes a mounting plate 31, which is fixedly mounted on the mounting platform 2. At the same time, two sets of second cylinders 32 are oppositely arranged at both ends of the mounting plate 31. At the same time, two sets of slide rails 34 are arranged on the mounting plate 31. A connecting plate 33 is slidably mounted on the slide rails 34. One end of the connecting plate 33 is fixedly connected to the output end of the second cylinder 32, so that the two connecting plates 33 are adapted to approach or move away from each other under the drive of the second cylinder 32;

[0027] At the same time, a fastening assembly 5 is arranged on the connecting plate 33. The fastening assembly 5 includes a receiving groove 51, which is arranged on the connecting plate 33. At the same time, a bidirectional screw 52 is arranged in the receiving groove 51. One end of the bidirectional screw 52 is connected by a bearing inside the receiving groove 51, and the other end penetrates through the receiving groove 51 and is fixedly provided with a turning handle 53. By controlling the rotation of the turning handle 53, the bidirectional screw 52 can be driven to rotate;

[0028] The bidirectional screw 52 includes a first section and a second section. The lengths of the first end and the second end are the same and have threads with opposite spiral directions. At the same time, two sets of oppositely arranged clamping rings 54 are arranged on the first section and the second section. When the turning handle 53 is rotated, the two clamping rings 54 approach each other, thereby clamping the motor. The fastening assembly 5 is used to limit the motor to be processed, so that the bearing will not deviate from the predetermined position during press-fitting.

[0029] When bearing press-fitting operation needs to be performed on the motor, first place the motor between the two connecting plates 33, and then rotate the turning handle 53 according to the size of the motor, so that the distance between the two clamping rings 54 is adapted to the size of the motor. Then start the second cylinder 32, so that the two connecting plates 33 approach each other, and further make the two fastening assemblies 5 limit the motor. Finally, start the first cylinder 41 to perform the bearing press-fitting operation on the motor.

[0030] In summary, by setting the fixing device 3, the motor is firmly fixed and will not shift. At the same time, through the setting of the fastening assembly 5, it can be adapted to motors of different sizes, increasing the practicability of the device.

[0031] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
