[0029] Embodiment

[0030] As Figure 1-2 shown, the present utility model provides a pneumatic outer shell locking tooling, including: a bracket 1, a support 2, a bearing plate 3, and a pneumatic control mechanism 4. The supports 2 are correspondingly arranged at both ends of the upper surface of the bracket 1. A plurality of through grooves 200 are provided on the supports 2. The bearing plate 3 is arranged on the bracket 1 and is arranged between the two supports 2. Each pneumatic control mechanism 4 is evenly and symmetrically distributed in the through grooves 200. The pneumatic control mechanism 4 includes: a first cylinder 400, a connecting plate 410, and a pressing rod 420. The first cylinder 400 is arranged vertically, the connecting plate 410 is arranged horizontally. One end of the connecting plate 410 is fixed on the output shaft of the first cylinder 400, and an adjusting hole is provided at the other end. The pressing rod 420 is arranged vertically in the adjusting hole. Place the product to be locked on the bearing plate 3, control the first cylinder 400 to drive the pressing rod 420 to move downward to press the product tightly on the bearing plate 3. It should be noted that a plurality of pneumatic control mechanisms 4 are simultaneously connected to the PLC control system. During the process of pressing down the product, each pressing rod 420 moves downward synchronously. Thus, the product is tightly pressed on the bearing plate 3 stably, so that the product will not be in a situation of one high and one low, which is beneficial to screwing the product and reducing the phenomenon of screw slipping of the product.

[0031] In this embodiment, a rubber pressing plate 430 is further included. The rubber pressing plate 430 is arranged at the lower end of the pressing rod 420. The rubber pressing plate 430 plays a buffering role when the pressing rod 420 contacts the product, reducing the damage to the pressing part of the product by the pressing rod 420.

[0032] In this embodiment, in order to further increase the adaptability of the device, the outer surface of the pressing rod 420 is provided with threads, and the adjusting hole is provided with internal threads. Rotating the pressing rod 420 can adjust the position of the pressing rod 420 in the adjusting hole. Preferably, a rotating block is provided at the upper end of the pressing rod 420, and the outer surface of the rotating block is provided with an anti-slip structure.

[0033] In this embodiment, bumps 5 are respectively provided at the ends of the two supports 2 close to each other, which can increase the bearing area of the product to be locked.

[0034] In this embodiment, it further includes: a second cylinder, which is vertically arranged, and the output shaft of the second cylinder is fixed to the bottom surface of the bearing plate 3. The second cylinder enables the product on the bearing plate 3 to be subjected to not only the pressure from top to bottom but also the thrust from bottom to top, increasing the clamping ability of the product.

[0035] It should be noted that, in order to further increase the adaptability of the device, preferably, a plurality of third cylinders are provided on the upper surface of the bracket 1, and the output shafts of the third cylinders are connected to the sides of the supports 2. The third cylinders can control the two supports 2 to approach or separate from each other.
