[0002] During the production and processing of the motor shaft of a roller shutter door motor, grinding, cutting, or grooving are required. Generally, the motor shaft needs to be clamped using a clamping fixture, and then the fixture is placed on a machine tool for processing. Currently, when processing the keyway of the motor shaft, the existing clamping devices are complex in structure and time-consuming to clamp the motor shaft. Therefore, a new clamping device for processing motor shafts is needed. Utility Model Content

[0003] In view of this, this application provides a clamping device for machining the motor shaft of a roller shutter door, so as to solve the technical problem that the existing clamping devices have a complex structure and are time-consuming when clamping the motor shaft.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A clamping device for machining a roller shutter door motor shaft is used to clamp the motor shaft on a milling machine for machining a keyway on the motor shaft. The clamping device includes:

[0006] A frame, which is fixed on the milling machine worktable;

[0007] A drive mechanism is mounted at the lower end of the frame;

[0008] A pressing mechanism is provided at the upper end of the frame;

[0009] A locking mechanism is provided, wherein the locking mechanism is movably mounted on the frame, the upper end of the locking mechanism is connected to the pressure block mechanism, and the lower end of the locking mechanism is connected to the drive mechanism;

[0010] The locking mechanism drives the pressing block mechanism to clamp the motor shaft to be processed, and the driving mechanism can drive the locking mechanism to unlock the clamped motor shaft.

[0011] Furthermore, the drive mechanism includes:

[0012] A cam, the cam being connected to a rotating shaft mounted on the frame;

[0013] A handle is fixed to the outer end of the rotating shaft and located at the front end of the cam.

[0014] Furthermore, the locking mechanism includes:

[0015] A pull rod, which slides through the guide seat of the frame, and the upper end of the pull rod is connected to the pressing block mechanism;

[0016] A pressure roller is connected to the lower end of the pull rod, and the pressure roller is in contact with the cam;

[0017] A compression spring is sleeved on the lower part of the pull rod, and the compression spring presses against the spring seat of the guide seat and the pull rod.

[0018] Furthermore, the pressing mechanism includes:

[0019] A support, which is mounted on the horizontal plate of the frame;

[0020] A pressure seat, wherein the pressure seat is hinged to the pull head of the locking mechanism, and the pressure seat is slidably connected to the upright seat;

[0021] A screw, the screw being threadedly connected to an extension seat disposed on the pressure seat;

[0022] A nut, which is threadedly engaged with the screw, is used to lock the screw onto the extension seat.

[0023] Furthermore, the sliding part of the pressure seat is slidably connected to the sliding groove of the upright seat.

[0024] Furthermore, an upper V-shaped block is connected to the bottom of the screw, and a lower V-shaped block corresponding to the upper V-shaped block is installed on the frame.

[0025] Furthermore, the lower V-block is adapted to the upper V-block to clamp the motor shaft.

[0026] Furthermore, the frame is supported by a mounting block, which is fixed to the milling machine worktable.

[0027] As can be seen from the above technical solution, the advantages of this utility model are:

[0028] This application includes a locking mechanism and a pressing mechanism. The locking mechanism drives the pressing mechanism to clamp the motor shaft to be processed. Specifically, the compression spring of the locking mechanism remains compressed, causing the upper V-block of the pressing mechanism to press the motor shaft to be processed against the lower V-block, thus achieving reliable clamping of the motor shaft. Compared with the existing clamping devices that use cylinders or hydraulic cylinders, the structure of this application is simple, reducing the number of hydraulic and pneumatic circuits and related components. In addition, in this application, the clamping of the motor shaft by the upper and lower V-blocks can be released by operating the cam. Then, the operator can remove the processed motor shaft, place the motor shaft to be processed, and release the operation of the cam. Under the action of the compression spring, the clamping of the motor shaft to be processed is achieved. The cam operation is simple and convenient. Therefore, this application is highly efficient and saves time when clamping motor shafts. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0036] refer to Figures 1 to 4 ,like Figure 1As shown, this embodiment provides a clamping device for machining the motor shaft of a roller shutter door, including a frame 1, a drive mechanism, a pressing block mechanism, and a locking mechanism, as follows. Figure 1 and Figure 4 As shown, the drive mechanism is installed at the front end of the frame 1. The drive mechanism includes a cam 17 and a handle 18. The cam 17 is fixedly connected to a rotating shaft 181 rotatably mounted on the frame 1. The handle 18 is fixed to the outer end of the rotating shaft 181 and is located at the front end of the cam 17. The end of the handle 18 extends outward from the frame 1, which facilitates operation by the operator.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, a horizontal plate 11 is mounted on the upper surface of the frame 1. A limiting through hole 111 is opened on the horizontal plate 11, and a guide sleeve 2 is installed in the limiting through hole 111. The locking mechanism includes a pressure roller 16, a compression spring 14, and a pull rod 31. The pull rod 31 passes upward through a guide seat 13 mounted on the frame 1. The upper end of the pull rod 31 is slidably engaged with the guide sleeve 2 located at the limiting through hole 111. The upper end of the pull rod 31 extends upward out of the guide sleeve 2 and is connected to a pull head 3. The pressure roller 16 is rotatably mounted on the lower end of the pull rod 31 and can contact the cam surface of the cam 17. The compression spring 14 is sleeved on the outer end of the pull rod 31. The upper end of the compression spring 14 presses against the lower end surface of the guide seat 13, and the lower end presses against the upper end surface of the spring seat 15 fixed to the lower end of the pull rod 31.

[0038] like Figure 1 , Figure 2 As shown, the pressing mechanism includes a stand 4, a pressing seat 6, a screw 7, and a nut 71. The stand 4 is fixed on the upper surface of the horizontal plate 11. The pressing seat 6 is hinged to the upper end of the pull head 3 via a hinge shaft 5. A sliding part 62 is installed on the left side of the pressing seat 6, and a sliding groove 41 is opened on the right side of the stand 4. The sliding part 62 is slidably connected to the sliding groove 41. An extension seat 61 is installed on the right side of the pressing seat 6. The screw 7 is threadedly connected to the extension seat 61. The upper end of the screw 7 extends outward to the upper end of the extension seat 61, and the lower end of the screw 7 extends outward to the lower end of the extension seat 61. An upper V-shaped block 72 is connected to the lower end of the screw 7. The nut 71 is threadedly engaged with the upper end of the screw 7, and the nut 71 can abut against the upper surface of the extension seat 61. Tightening the nut 71 can make the lower surface of the nut 71 tightly abut against the upper surface of the extension seat 61, thereby locking the screw 7 onto the extension seat 61.

[0039] like Figure 1 Figure 2 and Figure 4 As shown, a support plate 12 is installed on the front end face of the upper end of the frame 1, and a V-shaped block 9 is installed on the support plate 12.

[0040] like Figure 3As shown, the lower V-block 9 is adapted to the upper V-block 72. The lower V-block 9 and the upper V-block 72 are used to clamp the motor shaft 100 with the keyway to be machined, so that the milling machine can mill the keyway on the motor shaft 100.

[0041] Preferably, a mounting block 19 is installed at the lower end of the frame 1 for support, and the mounting block 19 is fixed on the surface of the milling machine worktable 200.

[0042] Working principle: Before clamping the motor shaft 100, first rotate the handle 18 clockwise. The handle 18 drives the rotating shaft 181 to rotate clockwise, and drives the cam 17 to rotate synchronously. This causes the cam 17's convex part to drive the pressure roller 16 to move upward, which in turn causes the pressure roller 16 to drive the pull rod 31 to move upward relative to the guide seat 13 (causing the spring seat 15 to compress the compression spring 14). The upward movement of the pull rod 31 drives the upper pull head 3 to move upward, causing the sliding part 62 of the pressure seat 6 to slide upward at the slide groove 41. At the same time, the pressure seat 6 drives the extension seat 61 to move upward, causing the upper V-block 72 to move upward relative to the lower V-block 9. Then, the motor shaft 100 with the keyway to be processed is placed stably on the lower V-block 9. Inside the V-groove of V-block 9, the handle 18 is then rotated counterclockwise to reset. The handle 18 drives the rotating shaft 181 to rotate, and drives the cam 17 to rotate counterclockwise synchronously, so that the convex part of the cam 17 no longer presses against the pressure roller 16. At this time, under the reset action of the compression spring 14, the pull rod 31 moves down, driving the pull head 3 set at the upper end to move down, driving the pressure seat 6 to drive the extension seat 61 to move down, so that the V-groove of the upper V-block 72 presses on the motor shaft 100 (the compression spring 14 is in a compressed state), so that the upper V-block 72 and the lower V-block 9 can reliably clamp the motor shaft 100 (after the device is installed, the compression spring 14 is always in a compressed state).

[0043] In this application, the distance between the upper V-block 72 and the lower V-block 9 can be adjusted by adjusting the position of the screw 7 relative to the extension seat 61, so as to clamp motor shafts 100 of different diameters.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
