[0050] This utility model provides a clamping device for repairing mechanical parts in tobacco re-drying. (See reference...) Figure 1The invention includes a repair table 1, a work plate 2 positioned above the repair table 1, a positioning mechanism 3 located on one side of the repair table 1, and a clamping mechanism 4 mounted on and slidably connected to the positioning mechanism 3. In use, the workpiece to be repaired is placed on the work plate 2, and the operator stands beside the repair table 1 to perform the repair. Before the operator begins repair, the workpiece must be secured to prevent secondary movement during the repair process. To secure the workpiece, the positioning mechanism 3 is moved until the clamping mechanism 4 mounted on the positioning mechanism 3 is positioned above the workpiece. Then, the clamping mechanism 4 is activated, pressing the workpiece from top to bottom, thus securing and limiting the workpiece and preventing secondary movement during the repair process.

[0051] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1 The positioning mechanism 3 includes a first driving member 31, and a transition block 32 slidably connected to the drive shaft of the first driving member 31. The clamping mechanism 4 is disposed on the transition block 32. In use, the first driving member 31 is activated, and the transition block 32 moves along the drive shaft of the first driving member 31, either closer to or away from the maintenance table 1, thereby adjusting the relative position of the clamping mechanism 4 so that the clamping mechanism 4 can fix and limit workpieces of different sizes and shapes to be repaired. For illustration, the first driving member 31 is selected from any one of a stepper motor, a DC geared motor, or a servo motor, preferably a servo motor and a ball screw. Here, a manual driving embodiment is also provided: when the first driving member 31 is manually driven, the drive shaft of the first driving member 31 is a ball screw, and a wheel is also provided at the end of the drive shaft of the first driving member 31. The operator can rotate the wheel to rotate the drive shaft of the first driving member 31.

[0052] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1 The clamping mechanism 4 includes a support rod 41 mounted on the adapter block 32 and extending upward, a crossbar 42 mounted on the support rod 41 and extending towards the maintenance table 1, and a clamping member 5 mounted on the crossbar 42 with its working end facing downward. For illustration, the support rod 41 is preferably perpendicular to the adapter block 32, and the crossbar 42 is preferably perpendicular to the support rod 41.

[0053] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1The clamping member 5 includes a second driving member 51 disposed on the crossbar 42 and a clamping block 52 disposed at the top end of the drive shaft of the second driving member 51 and rotatably connected thereto. For illustration, the top end of the drive shaft of the second driving member 51 is typically provided with a rotating block, and the clamping block 52 can rotate around the rotating block. The material of the clamping block 52 is preferably rubber. For further explanation, the first driving member 31 is selected from any one of a stepper motor, a DC geared motor, or a servo motor, preferably a servo motor.

[0054] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1 The clamping member 5 further includes a third driving member 53 disposed on one side of the second driving member 51, an adjusting slider 54 disposed on the drive shaft of the third driving member 53, and an adjusting slide rail 55 disposed on the back of the clamping block 52 and slidably connected to the adjusting slider 54. For illustration, if the workpiece to be repaired is tilted or uneven, it is difficult to clamp the workpiece by applying pressure only from top to bottom; therefore, the clamping block 52 needs to be at a certain angle to clamp the workpiece. Figure 1 As shown, when the drive shaft of the third drive member 53 retracts, the adjusting slider 54 moves upward. Simultaneously, the adjusting slide rail 55 tilts upward to follow the upward movement of the adjusting slider 54; conversely, the adjusting slide rail 55 falls downward to follow the downward movement of the adjusting slider 54. Therefore, by adjusting the extension and retraction of the drive shaft of the third drive member 53 according to the shape, size, and relative position of the workpiece, the angle of the clamping block 52 can be adjusted. This allows for adjustment of the angle of the clamping block 52 when encountering workpieces of different shapes, enabling the clamping member 5 to fix and limit workpieces of different shapes, thus improving the adaptability of this invention. As a supplementary explanation, a transition plate is provided on the side wall of the second drive member 51, and the third drive member 53 is rotatably connected to the transition plate. When the drive shaft of the third drive member 53 extends or retracts, the third drive member 53 can slightly rotate around the transition plate as a fulcrum to more flexibly achieve the extension and retraction of the drive shaft.

[0055] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1The repair table 1 has an upward-facing mounting slot 11, and a fourth driving component 12 is installed in the mounting slot 11. The drive shaft of the fourth driving component 12 is connected to the bottom of the work plate 2. For illustration, when the operator needs to repair different areas of the workpiece, the fourth driving component 12 can be activated, causing the work plate 2 to rotate around the drive shaft of the fourth driving component 12, thereby rotating the area of ​​the workpiece to be repaired to the operator's view, eliminating the need for manual adjustment of the workpiece. Further explanation is that the fourth driving component 12 is selected from any one of a stepper motor, a DC geared motor, or a servo motor, preferably a servo motor.

[0056] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1 The bottom of the working plate 2 is also provided with a transmission gear 21, and the drive shaft of the fourth drive member 12 is provided with a drive gear 13 that meshes with the transmission gear 21. For illustration, the drive gear 13 and the transmission gear 21 are usually driven by a large gear driving a small gear, with the drive gear 13 being a large gear and the transmission gear 21 being a small gear. This gear transmission method can improve the stability of the working plate 2 when it rotates.

[0057] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1 The repair bench 1 is further provided with an upward-facing guide groove 14, and the bottom of the work plate 2 is provided with a guide rod 22 that is slidably connected to the guide groove 14. For illustration, the guide groove 14 has an annular cross-sectional shape, and the bottom of the guide rod 22 is provided with a roller. When the work plate 2 rotates, the roller at the bottom of the guide rod 22 also rolls along the guide groove 14, providing support for the work plate 2 and improving its stability during rotation. Typically, the bottom of the work plate 2 is provided with multiple sets of symmetrical guide rods 22 to further enhance its stability during rotation.

[0058] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1 The repair table 1 has two independently controllable positioning mechanisms 3 on opposite sides, and each positioning mechanism 3 is equipped with an independently controllable clamping mechanism 4. For illustration, the two moving and two clamping mechanisms 4 allow the operator to select the appropriate clamping mechanism 4 to clamp the workpiece to be repaired according to the situation, improving the flexibility of this invention and the stability when clamping the workpiece.

[0059] The pressing device for repairing mechanical parts in tobacco re-drying provided in this embodiment of the utility model is described in reference to... Figure 1The drive shafts of the first drive members 31 in the two positioning mechanisms 3 are connected by an adapter rod 15 located in the maintenance table 1. For illustration, the adapter rod 15 rotates synchronously with the drive shafts of the two first drive members 31; regardless of which drive shaft rotates, the other drive shaft will rotate synchronously. Typically, both drive shafts of the two first drive members 31 use ball screws, but the balls in the adapter block 32 are arranged in opposite directions. That is, the two adapter blocks 32 will synchronously move closer to or further away from the maintenance table 1, thereby achieving a mirror image arrangement of the two positioning mechanisms 3.

[0060] This utility model also provides a method of using a clamping device for repairing mechanical parts in tobacco re-drying, which includes at least the following steps:

[0061] Step 1) First, place the workpiece to be repaired on the work plate 2;

[0062] Step 2) Activate the fourth drive unit 12 to rotate the area of ​​the workpiece to be repaired on the work plate 2 to the operator's face;

[0063] Step 3) Move the positioning mechanism 3 until the clamping mechanism 4 is above the workpiece to be repaired;

[0064] Step 4) Activate the third drive unit 53 and adjust the angle of the clamping block 52 so that it can match the workpiece to be repaired;

[0065] Step 5) Activate the second drive unit 51 to make the clamping block 52 hold the workpiece to be repaired.

[0066] If the angle of the clamping block 52 is not adjusted to the most stable position at once, the second motor can be driven to lift the clamping block 52 slightly upward, and steps 4) and 5) can be repeated until the clamping block 52 can hold the workpiece under repair to the maximum extent.

[0067] Once one of the repaired areas of the workpiece has been repaired, steps 1) to 5) can be repeated until all repaired areas of the workpiece have been repaired.

[0068] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
