[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please see Figure 1-5 As shown, this utility model is a metal casting clamping device, including a base plate 1 and a support plate 2, and further including: a cylinder 3 is provided in the middle of the outer wall of the support plate 2, and a housing 4 is fixedly connected to the inner wall of the support plate 2. The housing 4 is hollow to facilitate the installation of the clamping mechanism, and the output end of the cylinder 3 passes through the support plate 2 and is provided in the inner wall of the housing 4. A sliding plate 5 is fixedly connected to the output end of the cylinder 3, and the cylinder 3 can drive the sliding plate 5 to move inside the housing 4.
[0026] The drive mechanism, located inside the housing 4, is used to drive the rack 9 to slide. The drive mechanism includes a first connecting rod 6, a second connecting rod 7, a sector gear 8, and a rack 9. The first connecting rod 6 is rotatably connected to both ends of the sliding plate 5, and two sets of the first connecting rod 6 are provided to more stably drive the second connecting rod 7 to move. The second connecting rod 7 is rotatably connected to the other end of the first connecting rod 6. The second connecting rod 7 can drive the sector gear 8 to rotate. The sector gear 8 is connected to the other end of the second connecting rod 7. The rack 9 is located inside the housing 4 and meshes with the sector gear 8. When the cylinder 3 is started, the sliding plate 5 drives the first connecting rod 6 to move. When the first connecting rod 6 moves, it drives the second connecting rod 7, causing the second connecting rod 7 to drive the sector gear 8 to rotate, and then the sector gear 8 drives the rack 9 to move.
[0027] The rack 9 has grooves 10 at both ends. A slider 11 is fixedly connected to the inner wall of the housing 4, and the slider 11 is located inside the groove 10. The size of the groove 10 is larger than that of the slider 11, so that the rack 9 can slide without obstruction. At the same time, the rack 9 can be connected inside the housing 4 to avoid unstable meshing between the rack 9 and the sector gear 8, which would lead to failure to clamp. A positioning rod 12 is fixedly connected to the side end of the rack 9. The positioning rod 12 allows the positioning block 14 to slide on its outer wall. The upper end of the positioning rod 12 has a threaded hole 13. The threaded holes 13 are linearly and evenly distributed and penetrate the housing 4. The positioning block 14 can be changed according to the size of the metal casting. It can be fixed by the threaded hole 13 and the bolt. The positioning block 14 is bolted to the side end of the positioning rod 12. The positioning block 14 is U-shaped. A first clamping plate 15 is provided on the side wall of the housing 4. A second clamping plate 16 is rotatably connected to both sides of the first clamping plate 15.
[0028] A column 17 is fixedly connected to both sides of the lower end of the first clamping plate 15 and one side of the lower end of the second clamping plate 16. The column 17 passes through the second clamping plate 16 and is disposed inside the second clamping plate 16. The column 17 is rotatably connected to the second clamping plate 16. A spring 18 is provided on the outer wall of the column 17. The spring 18 can realize the pressing action of the second clamping plate 16 and limit the second clamping plate 16 to avoid the second clamping plate 16 shaking, which would cause the connection between the second clamping plate 16 and the first clamping plate 15 to be unstable, and thus make it impossible to fix the second clamping plate 16 when adjusting the angle.
[0029] Fixing blocks 19 are fixedly connected to both sides of the upper end of the first clamping plate 15 and one side of the upper end of the second clamping plate 16. The fixing blocks 19 can cooperate with the rotating block 21 to fix the first clamping plate 15 and the second clamping plate 16. A slot is opened in the middle of the lower end face of the fixing block 19. The slot can cooperate with the column at the upper end of the rotating block 21 to fix the fixing block 19 and the rotating block 21. A pin 20 is fixedly connected to the lower end face of the fixing block 19. The pins 20 are arranged in a circular array around the center of the fixing block 19. The rotating block 21 is set at the lower end of the pin 20. The pins 20 can cooperate with the pin hole 22 to realize the angle adjustment. The rotating block 21 is fixedly connected to the upper end of the second clamping plate 16. A column is fixedly connected to the middle of the upper end face of the rotating block 21. The upper end face of the rotating block 21 has a pin hole 22, which is arranged in a circular array around the center of the rotating block 21.
[0030] Working principle: First, place the equipment in a suitable position. Then, according to the shape of the metal casting to be clamped, press the second clamping plate 16. When the spring 18 is in the compressed state, the rotating block 21 will disengage from the fixed block 19. Then, by rotating the second clamping plate 16, the angle of the second clamping plate 16 can be adjusted according to the different metal castings. After adjusting to the appropriate angle, release the second clamping plate 16. Under the elastic force of the spring 18, the second clamping plate 16 can be effectively fixed. Then, according to the shape of the metal casting to be clamped, the second clamping plate 16 can be clamped. The size of the metal casting is determined by adjusting the positioning block 14 on the positioning rod 12 to a suitable position and fixing it with bolts. Then, the metal casting is placed between the clamping plates. Finally, the cylinder 3 is activated, and the sliding plate 5 drives the first connecting rod 6 to move. When the first connecting rod 6 moves, it drives the second connecting rod 7, which in turn drives the sector gear 8 to rotate. Then, the sector gear 8 drives the rack 9, which in turn enables the first clamping plate 15 to drive the second clamping plate 16 to move towards the center, thereby achieving the clamping of the metal casting.
[0031] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
