[0027] Example 1

[0028] A clamping device for keyboard assembly, such as Figures 1 to 5 As shown, the device includes a fixed plate 1. A guide groove 2 is provided on the top outer wall of the fixed plate 1. A placement platform 3 is provided on the top of the fixed plate 1 and is slidably connected to the inner wall of the guide groove 2. Fixed clamping blocks 4 and two side clamping blocks 6 are respectively provided on the front side and the left and right sides of the top outer wall of the placement platform 3. The side clamping blocks 6 are connected to the placement platform 3 through an adjustment assembly. An electric push rod 5 located on one side of the fixed clamping block 4 is installed on the outer wall of the fixed plate 1. The telescopic end of the electric push rod 5 is connected to the fixed clamping block 4.

[0029] The adjustment assembly includes multiple positioning slots 8 and positioning blocks 9. The multiple positioning slots 8 are all opened on the top outer wall of the placement platform 3 and are arranged in a straight line. The positioning blocks 9 are fixedly connected to the bottom outer wall of the side clamping block 6. The positioning blocks 9 are inserted into the positioning slots 8 for limiting. The bottom outer wall of the positioning block 9 and the bottom inner wall of the positioning slot 8 are both fixedly connected with magnet pieces 10, and the magnetic poles of the magnet pieces 10 connected to the positioning blocks 9 and the positioning slots 8 are opposite.

[0030] The top outer wall of the fixed plate 1 is fixedly connected to a mounting bracket 12 located on the side away from the fixed clamping block 4. A movable plate 14 is slidably fitted on the outer wall of the mounting bracket 12. An electric push rod 13 with its telescopic end connected to the movable plate 14 is installed on the top outer wall of the mounting bracket 12. A guide rod 15 with its slidable fit is provided on the outer side of the mounting bracket 12. A positioning strip 16 is fixedly connected to the bottom outer wall of one end of the movable plate 14. A contact plate 17 is connected to the side wall of the positioning strip 16. A pressure sensor 18 with its detection end in contact with the contact plate 17 is provided inside the positioning strip 16.

[0031] The top sidewalls of the fixed clamping block 4 and the two side clamping blocks 6 are all provided with guide slopes 7 to provide guidance.

[0032] The electric push rod 5, electric push rod 13, and pressure sensor 18 are all electrically connected to the controller, which can be any existing mature technology such as a PLC that can achieve the control effect.

[0033] In use, the fixing plate 1 is fixed to the workbench with bolts. The keyboard body is placed above the placement platform 3. The side clamps 6 and the fixing clamps 4 limit the position of the keyboard body. During placement, the guide slope 7 guides the keyboard body so that the keyboard body does not need to be completely aligned with the fixing clamps 4 and the side clamps 6. The position can be finely adjusted so that the keyboard body falls into the space enclosed by the fixing clamps 4 and the side clamps 6. Then, the electric push rod 1 5 pushes the placement platform 3 to move along the guide groove 2 towards the moving plate 14. One side of the keyboard body first contacts the contact plate 17. The pressure sensor 18 detects the pressure, and the electric push rod 2 13 pushes the moving plate 14 down to press on the upper surface of the keyboard body. When clamping keyboard bodies of different specifications, the side clamps 6 are lifted to overcome the magnetic attraction between the magnets 10. The positioning block 9 is pulled out from one positioning groove 8. The corresponding positioning groove 8 is selected according to the specifications of the keyboard body and the positioning block 9 is inserted. The magnetic attraction between the magnets 10 fixes the side clamps 6. The above operation is repeated for the other side clamps 6 to complete the adjustment.

[0034] With the magnetic component, the distance between the side clips 6 can be easily adjusted according to the specifications of the keyboard body, making it easy to clamp keyboard bodies of different sizes and convenient to adjust.

[0035] By setting the guide ramp 7, the keyboard body is guided when it is placed, so that the keyboard body does not need to be completely aligned with the fixed clamp 4 and the side clamp 6. The position can be finely adjusted so that the keyboard body falls into the space enclosed by the fixed clamp 4 and the side clamp 6.

[0036] Example 2

Figure 4 As shown, multiple rollers 11 are rotatably connected to the bottom outer wall and the side wall of the placement platform 3, and a limiting groove that cooperates with the rollers 11 is opened on the inner wall of the guide groove 2.

[0038] When the placement platform 3 moves along the guide groove 2, the roller 11 can convert the sliding friction between the placement platform 3 and the guide groove 2 into rolling friction, thereby reducing friction and wear.

[0039] By incorporating rollers 11, the sliding friction between the placement platform 3 and the guide groove 2 can be transformed into rolling friction, thereby reducing friction and wear.

[0040] Working principle: The fixing plate 1 is fixed to the worktable with bolts. The keyboard body is placed above the placement platform 3. The side clamps 6 and the fixing clamps 4 limit the position of the keyboard body. During placement, the guide slope 7 guides the keyboard body, so that the keyboard body does not need to be completely aligned with the fixing clamps 4 and the side clamps 6. It can be finely adjusted to allow the keyboard body to fall into the space enclosed by the fixing clamps 4 and the side clamps 6. Then, the electric push rod 5 pushes the placement platform 3 to move along the guide groove 2 towards the moving plate 14. The roller 11 can reduce the sliding friction between the placement platform 3 and the guide groove 2. The friction is converted to rolling friction, reducing friction and wear. One side of the keyboard body first contacts the contact plate 17. The pressure sensor 18 detects the pressure, and the electric push rod 13 pushes the moving plate 14 down to press on the upper surface of the keyboard body. When clamping keyboard bodies of different specifications, the side clamping block 6 is lifted to overcome the magnetic attraction between the magnet pieces 10, and the positioning block 9 is pulled out from one positioning groove 8. The positioning groove 8 corresponding to the keyboard body specification is selected and the positioning block 9 is inserted. The magnetic attraction between the magnet pieces 10 fixes the side clamping block 6. The above operation is repeated for the other side clamping block 6 to complete the adjustment.
