[0027] When cutting the bar, it is necessary to manually place the bar on the workpiece table of the metal band saw, and then clamp it with a manual clamping structure, and move the clamped bar close to the moving saw band through the moving structure 3 to perform the cutting action. However, in the prior art, it is not convenient to adjust the angle of the bar after it is clamped, and it also needs to be manually clamped in advance. There is a lack of a structure that can automatically clamp and fix the bar during movement.

[0028] To do this, see Figure 1-6 The utility model provides a clamping angle adjustment device for a metal band sawing machine, comprising: a band sawing machine body 1, a moving table 2 is slidably arranged on the workpiece table of the band sawing machine body 1, a moving structure 3 is connected between the bottom end of the moving table 2 and the workpiece table of the band sawing machine body 1, and a rotating table 5 is arranged on the top of the moving table 2;

[0029] It also includes an angle adjustment structure 4 and a synchronous transmission clamping structure 6. The angle adjustment structure 4 is installed on the rotating table 5 and the moving table 2. The angle adjustment structure 4 can facilitate the angle fine adjustment of the bar material at the clamping height on the rotating table 5.

[0030] The synchronous transmission clamping structure 6 is installed on the rotating table 5 and the band saw machine body 1. The synchronous transmission clamping structure 6 can automatically clamp and fix the bar material when the moving structure 3 drives the moving table 2 to move left to prepare for cutting.

[0031] Further as Figure 1-6As shown, it is worth explaining in detail that in order to enable the moving table 2 to automatically move to the left or right and realize the moving transportation of the bar material, a moving structure 3 is provided, including a moving seat 31 fixed to the bottom end of the moving table 2, and the vertical section of the moving seat 31 is a convex structure. The moving seat 31 is slidably connected to the moving groove provided on the workpiece table of the band saw machine body 1. A screw rod 32 is threadedly connected to the moving seat 31, and the screw rod 32 is rotatably connected to the moving groove. The right end of the screw rod 32 extends to the outside of the band saw machine body 1 and is fixed to the output shaft of the motor 33. The motor 33 is fixed to the outside of the band saw machine body 1.

[0032] Further as Figure 1-6 As shown, it is worth specifically explaining that, in order to facilitate the adjustment of the angle of the rotating table 5, an angle adjustment structure 4 is provided, including a connecting shaft 41 fixedly connected at the center of the bottom end of the rotating table 5, the bottom end of the connecting shaft 41 is rotatably connected to the center of the top end of the moving table 2, the bottom end of the connecting shaft 41 extends to the cavity provided on the inner side of the moving table 2, and is fixedly connected to a worm gear 42, the outer side of the worm gear 42 is meshingly connected to a worm 43, the worm 43 is rotatably connected to the cavity provided on the inner side of the moving table 2 through a rotating shaft 44, the right end of the rotating shaft 44 extends to the outer side of the moving table 2, and is fixedly connected to a handle 45.

[0033] Further as Figure 1-6 As shown, it is worth explaining in detail that in order to enable the bar placed between the two clamping seats 69 to automatically clamp and fix the bar when the moving structure 3 drives the moving table 2 to move to the left, a synchronous transmission clamping structure 6 is set up, including two symmetrically arranged L-shaped outer rods 63 fixed to the outer side of the rotating table 5, and the same n-shaped pressing rod 62 is movably inserted on the two L-shaped outer rods 63, and the inner sides of the two L-shaped outer rods 63 are provided with movable cavities that are convenient for lifting and sliding the n-shaped pressing rod 62, and the edges on both sides of the top end of the n-shaped pressing rod 62 are provided with inclined surfaces a, and the inclined surface a on the left side of the top end of the n-shaped pressing rod 62 is movably overlapped with the inclined surface provided at one end of the guide plate 61. The other end of the guide plate 61 is fixed to the band saw machine body 1, and two symmetrically arranged upper pressing blocks 65 are fixed to the inner top wall of the N-shaped lower pressure rod 62. The inclined surfaces c set at the bottom ends of the upper pressing blocks 65 are movably overlapped on the inclined surfaces d set at the top ends of the lower pressing blocks 66. The bottom ends of the lower pressing blocks 66 are fixed with sliding seats 67 with convex vertical cross-sections. The top ends of the two sliding seats 67 are also fixed with clamping seats 69. The two sliding seats 67 are slidably connected to the same sliding groove set at the top of the rotating table 5. The two sides of the bottom end of the N-shaped lower pressure rod 62 are respectively connected to the inner bottom wall of the active cavity through springs a64, and a spring b68 is connected between the opposite ends of the two sliding seats 67.

[0034] Among them, the width of the guide plate 61 is larger than the diameter of the rotating table 5. When the rotating table 5 drives the n-shaped pressing rod 62 to move to the left along with the moving table 2, the top left inclined surface a of the n-shaped pressing rod 62 can be squeezed by the right end inclined surface b of the guide plate 61, so that the n-shaped pressing rod 62 can move downward.

[0035] In summary: when using the clamping and angle adjustment device for a metal band saw, the bar can be placed between the two clamping seats 69 and placed on the top of the rotating table 5, and by starting the motor 33, the screw 32 is rotated, so that the movable table 2 drives the bar on the rotating table 5 to move to the left. During the movement, the left inclined surface a of the top end of the n-shaped pressing rod 62 can be squeezed by the right end inclined surface b of the guide plate 61, and the n-shaped pressing rod 62 can move downward, causing the spring a64 to be compressed, and the other two upper pressing blocks 65 respectively press the lower pressing block 66, so that the two clamping seats 69 can move relative to each other, the spring b68 is compressed, and the bar placed therebetween can be clamped and fixed, and when the movable structure 3 continues to move, the two clamping seats 69 can continue to clamp and fix the bar, so as to facilitate the cutting of the metal band saw, and there is no need for manual clamping operation to fix the bar, thereby greatly improving the cutting efficiency.
