[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] This embodiment provides a side clamping device for shell parts, such as Figure 1 As shown, it includes a lateral clamping seat 1, a driving cylinder 2, a pressing plate 3, a pressing head 4, a push rod 6 and a bottom plate 7;

[0029] The lateral clamping seat 1 is fixedly mounted on the top of the base plate 7 by means of hexagon socket head screws.

[0030] The driving cylinder 2 is arranged at the bottom of the lateral clamping seat 1 and embedded in the bottom plate 7, and its piston is vertically upward. One end of the push rod 6 is threadedly connected to the piston of the driving cylinder 2, and the other end passes through the lateral clamping seat 1 and is rotatably connected to the first mounting plate 31 through the waist-shaped hole 63 arranged on the push rod 6 and the first shaft pin 61 passing through the waist-shaped hole 63. The length direction of the waist-shaped hole 63 is horizontal. A sliding bushing 5 is set between the push rod 6 and the lateral clamping seat 1. The sliding bushing 5 is fixedly connected to the lateral clamping seat 1 and is loosely matched with the push rod 6. The first shaft pin 61 passes through the waist-shaped hole 63. The setting of the waist-shaped hole 63 facilitates the forward and backward movement of the pressure plate 3. The driving cylinder 2 can be an oil cylinder or a pneumatic cylinder.

[0031] The pressure plate 3 is a triangular plate, whose first vertex protrudes outward to form a first mounting plate 31, whose second vertex protrudes outward to form a second mounting plate 32, and whose third vertex is recessed inward to form a mounting groove 33; the first mounting plate 31 is rotatably connected to the other end of the push rod 6; the second mounting plate 32 is rotatably connected to the lateral clamping seat 1 through the second shaft pin 62.

[0032] The pressing head 4 is installed in the installation groove 33 by means of an M6*14 hexagon socket head bolt and is used to tighten the side of the part to be processed.

[0033] During operation, the piston of the drive cylinder 2 moves vertically upward, the first shaft pin 61 and the second shaft pin 62 both rotate, and the pressure plate 3 decomposes the vertical force of the piston into horizontal and vertical forces, driving the third vertex of the pressure plate 3 to move toward the direction of the part to be processed, and the pressure head 4 presses against the side of the part to be processed to clamp it. When releasing, the piston of the drive cylinder 22 moves downward, and the third vertex of the pressure plate 3 moves away from the part to be processed to release the part.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or replacements within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
