Technical Field
[0001] This utility model relates to the field of auxiliary tooling for processing cigarette frame partitions, and in particular to an adjustable protective clamping tooling for processing cigarette frame partitions. Background Technology
[0002] Cigarette frames facilitate the placement of cigarette packs during production, simplifying procedures and reducing worker workload. Throughout the production and handling process, cigarette packs stored in frames can be stacked for inventory management; once issued, they serve only a storage function. Cigarette frame partitions are metal sheets installed within the frames for separation. During production, they require punching and shearing equipment. To ensure the accuracy of the hole positions, clamping and positioning are necessary. Existing clamping fixtures fix the partitions in place, but improper clamping force control during this process can easily deform the partitions, affecting their subsequent processing and resulting in wasted material.

[0029] The installation and use process of the adjustable protective clamping fixture for processing cigarette frame partitions of this utility model is as follows:
[0030] The installation process is as follows: First, the installer can install the bottom of the mounting frame 1 on the working ground.

[0031] II. In practical use, the operator can place the cigarette frame partition to be clamped between the first driving part 5 and the second driving part 6; then, the operator can control the drive motor 41 in the bidirectional drive part 4 to start. The drive motor 41 inputs a positive rotational torque through the motor axial reducer 43. The reducer 43 drives the rotating screw 45 to rotate clockwise through its installed power output shaft. Since the threaded holes on the first driving part 5 and the second driving part 6 have opposite thread directions, under the action of the threaded pushing force, the first driving part 5 and the second driving part 6 move relative to each other. At this time, under the drive of the first driving part 5 and the second driving part 6, the partition protective clamping assembly 7 on them moves relative to each other. When the clamping plate 75 in the partition protective clamping assembly 7 contacts the two sides of the cigarette frame partition, the back side of the clamping plate 75... The buffer spring 74 provides elastic buffering for the clamping plate 75 to prevent deformation of the smoke frame partition caused by the clamping plate 75 rigidly clamping it. After the clamping action is completed, the drive motor 41 stops working, and at this time, the hole-making operation can be performed on the smoke frame partition. When it is necessary to release the clamping action on the smoke frame partition, the operator can control the drive motor 41 to rotate in the opposite direction. The drive motor 41 inputs the rotation torque in the opposite direction through the motor axial reducer 43. The reducer 43 drives the rotating screw 45 to rotate counterclockwise through its installed power output shaft. Under the action of the threaded pushing force, the first driving part 5 and the second driving part 6 move in opposite directions. At this time, under the drive of the first driving part 5 and the second driving part 6, the partition protection clamping parts 7 on them move in opposite directions, and the clamping plate 75 releases the clamping operation on the smoke frame partition.
[0032] Specific Embodiment 2: As shown in the appendix to the specification of this utility model. Figure 5 As shown, in order to enable the adjustable protective clamping fixture for processing cigarette frame partitions of this utility model to be applicable to clamping and positioning cigarette frame panels with high structural strength and not easily deformed, in this embodiment, a threaded through hole is provided on the fixed bracket 71, and a limiting screw 76 for limiting the clamping plate 75 is screwed in the threaded through hole. In use, the top of the limiting screw 76 can tighten the clamping plate 75. At this time, when clamping and positioning cigarette frame panels with high structural strength and not easily deformed, the clamping plate 75 will not move backward under the tightening action of the limiting screw 76, and directly clamps the cigarette frame panel, thereby improving the working range of this utility model.
