Description

Technical Field

[0001] The present application relates to the technical field of fixtures, and in particular to a fixture for processing a printer shaft core. Background Art

[0002] The printer shaft core is a shaft that is slightly flattened at both ends. The main processing method is to use machine tools to clamp the unprocessed blank through the three-jaw chuck on the machine tool, and then use the turning tool to align the center of the blank, and then process it into a shaft core that is slightly flattened at both ends.

[0003] However, when processing an unprocessed blank, after processing one end of the blank, it is necessary to loosen the three-jaw chuck to remove the blank from the three-jaw chuck, then rotate the blank so that the other unprocessed end extends out of the three-jaw chuck, and then tighten the three-jaw chuck to fix the blank before processing it. This is very troublesome, and for this reason a fixture for processing the printer shaft core is needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a fixture for processing the printer shaft core, which is used to solve the technical problem of the existing technology that the processing of the two ends of the blank is relatively troublesome.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: A fixture for processing the printer shaft core, including a placement box, a connecting platform fixedly arranged on the upper surface of the placement box, a rotating body rotatably connected to the connecting platform, and three-jaw chucks installed on the left and right sides of the rotating body, the interior of the rotating body is hollow and is provided with a driving device for driving the three-jaw chuck to rotate, and the two opposite sides of the three-jaw chucks are each provided with a rotating shaft extending therefrom and connected as a whole, the rotating shaft is located in the rotating body and rotatably connected to the rotating body, and the axis of the rotating shaft is hollow and connected to the clamping port of the three-jaw chuck.

[0006] Furthermore, the driving device includes a driving motor fixedly arranged in the rotating body, a driven gear fixedly connected to the circumferential surface of the rotating shaft, and a driving gear fixedly connected to the output end of the driving motor, the driving gear engages with the driven gear, a power supply body for providing power is provided in the placement box, and the driving motor wires are connected to the power supply body.

[0007] Furthermore, a connecting circular opening is provided on the upper surface of the connecting platform, which passes through the connecting platform and places the box. A hollow shaft is fixed on the bottom surface of the rotating body for rotating the rotating body to connect to the connecting platform. The hollow shaft is inserted into the connecting circular opening and is connected to the rotating body.

[0008] By adopting the above technical solution, the blank to be processed is aligned with the clamping opening of the three-jaw chuck and inserted, so that the blank extends from the clamping opening of the other three-jaw chuck, and then the three-jaw chuck is twisted to clamp the blank. At this time, the driving motor is started to engage the driving gear to drive the driven gear, and the driven gear drives the rotating shaft to rotate, thereby rotating the two three-jaw chucks. Then the staff uses a turning tool to align the center of the blank, and can process both ends of the blank at the same time, or process both ends of the blank separately. That is, after processing one end, the driving motor is turned off, and then the rotating body is rotated to rotate the unprocessed end, and then the driving motor is started again to process this end, so that the staff does not need to re-align the center of the blank with the turning tool, thereby improving the processing efficiency and making it more convenient to process both ends of the blank. The setting of the connecting round port and the hollow shaft is to allow the connecting wires of the driving motor to pass through the hollow shaft through the connecting round port and be connected to the power supply body, so that when the rotating body rotates, the connecting wires of the driving motor will not wrap around the rotating body and hinder the rotation of the rotating body.

[0009] Furthermore, a connection hole whose center is parallel to the center of the connection circular opening is opened on the upper surface of the placement box, and a fixing structure for fixing the rotating body is provided on the upper surface of the placement box.

[0010] Furthermore, the fixing structure includes a fixing threaded column that is threadedly connected to the placement box through a connecting hole, and a connecting boss fixedly arranged on the front and rear sides of the circumference of the rotating body. The bottom surface of the connecting boss is provided with a connecting screw hole, and the fixing threaded column is threadedly connected to the connecting boss through the connecting screw hole.

[0011] By adopting the above technical solution, although the setting of the rotating body makes it more convenient for the staff to process the two ends of the blank, when the driving motor drives the three-jaw chuck to rotate, it may cause the rotating body to vibrate, causing the rotating body to rotate, causing the blank to deviate from the tool during processing. The setting of the fixed structure solves this technical problem. Before clamping the blank, the fixed threaded column is screwed upward so that the fixed threaded column is threadedly connected to the connecting boss to fix the rotating body. This can prevent the rotating body from rotating during processing, causing the blank to deviate from the tool during processing.

[0012] Furthermore, a rubber gasket is provided at the connection between the hollow shaft and the connection platform.

[0013] By adopting the above technical solution, the connection between the hollow shaft and the connecting platform is strengthened and the wear of the hollow shaft during rotation is reduced, thereby improving the service life of the hollow shaft.

[0014] Furthermore, a measuring ruler rotatably connected to the rotating body is provided on the top surface of the rotating body.

[0015] By adopting the above technical solution and setting a measuring ruler, the staff can measure the length of the two ends of the blank extending out of the three-jaw chuck, so as to facilitate the staff's processing.

[0016] Furthermore, a damping ring is provided at the connection between the measuring ruler and the rotating body.

[0017] By adopting the above technical solution, the damping ring is used to prevent the measuring ruler from rotating during the processing.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By placing the box, the rotating body, the connecting platform and the driving device, the blank to be processed is aligned with the clamping port of the three-jaw chuck and inserted, so that the blank extends from the clamping port of the other three-jaw chuck, and then the three-jaw chuck is twisted to clamp the blank. At this time, the driving motor is started to engage the driving gear to drive the driven gear, and the driven gear drives the rotating shaft to rotate, thereby rotating the two three-jaw chucks. Then the staff uses the turning tool to align the center of the blank, and can process both ends of the blank at the same time, or process one end of the blank. After processing one end, the driving motor is turned off, and then the rotating body is rotated to rotate the unprocessed end, and then the driving motor is started again to process that end, so that the staff does not need to re-align the center of the blank with the turning tool, which improves the processing efficiency and makes it more convenient to process both ends of the blank.

[0020] 2. Through the setting of the fixed structure, it is achieved that before clamping the blank, the fixed threaded column is screwed upward so that the fixed threaded column is threadedly connected to the connecting boss to fix the rotating body. This can prevent the rotating body from rotating during processing, causing the blank to deviate from the tool during processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present application is further described in detail below with reference to the accompanying drawings.

[0026] Example, see Figure 1 、 Figure 2 、 Figure 3 A fixture for processing a printer shaft core includes a placement box 1, a connecting platform 10 fixedly arranged on the upper surface of the placement box 1, a rotating body 2 rotatably connected to the connecting platform 10, and three-jaw chucks 11 installed on the left and right sides of the rotating body 2. The interior of the rotating body 2 is hollow and is provided with a driving device 3 for driving the three-jaw chuck 11 to rotate. The two opposite sides of the three-jaw chucks 11 each extend a rotating shaft 110 and are integrally connected. The rotating shaft 110 is located in the rotating body 2 and rotatably connected to the rotating body 2. The axis of the rotating shaft 110 is hollow and communicates with the clamping port of the three-jaw chuck 11. The driving device 3 The drive motor 30 is fixedly arranged in the rotating body 2, the driven gear 31 is fixedly connected to the circumference of the rotating shaft 110, and the drive gear 32 is fixedly connected to the output end of the drive motor 30. The drive gear 32 engages with the driven gear 31. A power supply body for providing power is provided in the placement box 1. The drive motor 30 is connected to the power supply body by wires. A connecting circular opening 100 is provided on the upper surface of the connecting platform 10 that passes through the connecting platform 10 and the placement box 1. A hollow shaft 20 is fixed on the bottom surface of the rotating body 2 for rotating the rotating body 2 and connecting to the connecting platform 10. The hollow shaft 20 is plugged into the hollow shaft 20. In the connecting circular opening 100, the hollow shaft 20 is connected to the rotating body 2, and the blank to be processed is aligned with the clamping opening of the three-jaw chuck 11 and inserted, so that the blank extends from the clamping opening of the other three-jaw chuck 11, and then the three-jaw chuck 11 is twisted to clamp the blank. At this time, the drive motor 30 is started to make the drive gear 32 engage and drive the driven gear 31, and the driven gear 31 drives the rotating shaft 110 to rotate, thereby rotating the two three-jaw chucks 11. Then the staff uses the turning tool to align the center of the blank, and can process both ends of the blank at the same time, or process one end of the blank. After processing one end, the drive is turned off. Motor 30, then rotates the rotating body 2 to make the unprocessed end rotate over, and then starts the driving motor 30 to process the end, so that the staff does not need to re-calibrate the center of the blank with a turning tool, which improves the processing efficiency and makes it more convenient to process both ends of the blank. The setting of the connecting circular port 100 and the hollow shaft 20 is to allow the connecting wires of the driving motor 30 to pass through the hollow shaft 20 through the connecting circular port 100 and be connected to the power supply body, so that when the rotating body 2 rotates, the connecting wires of the driving motor 30 will not wrap around the rotating body 2 and hinder the rotation of the rotating body 2.

[0027] Although the setting of the rotating body 2 makes it more convenient for the staff to process the two ends of the blank, when the driving motor 30 drives the three-jaw chuck 11 to rotate, it may cause the rotating body 2 to vibrate, causing the rotating body 2 to rotate, causing the blank to deviate from the tool during processing. In order to solve this technical problem, this embodiment provides a connecting hole 12 on the upper surface of the placement box 1, the center of which is parallel to the center of the connecting circular opening 100, and the upper surface of the placement box is provided with a fixing structure 4 for fixing the rotating body 2. The fixing structure 4 includes a fixing threaded column 40 that is threadedly connected to the placement box through the connecting hole 12, and a connecting boss 41 fixedly arranged on the front and rear sides of the circumference of the rotating body 2. The bottom surface of the connecting boss 41 is provided with a connecting screw hole, and the fixing threaded column 40 is threadedly connected to the connecting boss 41 through the connecting screw hole. Before clamping the blank, the fixing threaded column 40 is screwed upward so that the fixing threaded column 40 is threadedly connected to the connecting boss 41 to fix the rotating body 2. This can prevent the rotating body 2 from rotating during processing, which may cause the blank to deviate from the tool during processing.

[0028] In this embodiment, a rubber gasket 21 is provided at the connection between the hollow shaft 20 and the connecting platform 10 to strengthen the connection between the hollow shaft 20 and the connecting platform 10 and reduce the wear of the hollow shaft 20 during rotation, thereby increasing the service life of the hollow shaft 20.

[0029] In this embodiment, a measuring ruler 5 rotatably connected to the rotating body 2 is provided on the top surface of the rotating body 2, and a damping ring 50 is provided at the connection between the measuring ruler 5 and the rotating body 2. Through the setting of the measuring ruler 5, the staff can measure the length of the three-jaw chuck 11 extending from both ends of the blank to facilitate the staff's processing. The damping ring 50 is used to prevent the measuring ruler 5 from rotating during the processing.

[0030] The specific implementation process is as follows: first, screw the fixing threaded column 40 upwards so that the fixing threaded column 40 is threadedly connected to the connecting boss 41, and then the blank is pushed into the clamping port of one of the three-jaw chucks 11 so that the other end of the blank extends out from the clamping port of the other three-jaw chuck 11, and then rotate the measuring ruler 5, looking down from just above the measuring ruler 5 so that the distance extended at both ends of the blank is the same, and then screw the three-jaw chuck 11 to fix the blank, and then start the driving motor 30 to rotate the three-jaw chuck 11 for processing. When both ends of the blank are processed at the same time, the blank can be removed from the three-jaw chuck 11 after processing. First process one end of the blank, and then process the other end of the blank. After processing one end of the blank, screw the fixing threaded column 40 downwards, and then rotate the rotating body 2 to make the other end of the blank rotate over, and then screw the fixing threaded column 40 upwards so that the fixing threaded column 40 is threadedly connected to the connecting boss 41, and then process the other end of the blank.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
