[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-5 As shown, a fixed-point cutting fixture for mechanical manufacturing includes a processing table 1.

The drive fixing mechanism 2 can drive the support cutting mechanism 5 to move in the left and right directions. In combination with the drive fixing mechanism 2, the L-shaped indicator arrow 4 and the scale plate 3, a quantitative cutting effect on the workpiece can be achieved. When the workpiece needs to be cut multiple times, the cutting length can always be kept consistent.

[0029] An L-shaped plate 7 is fixedly connected to the upper left side of the processing table 1. An electric hydraulic rod 11 is fixedly connected to the upper side of the L-shaped plate 7. The lower end of the electric hydraulic rod 11 is fixedly connected to the mounting plate 9. A pressure block 8 is fixedly connected to the lower end of the mounting plate 9. A support block 6 is correspondingly provided on the lower side of the pressure block 8. The lower end of the support block 6 is fixedly connected to the processing table 1. The electric hydraulic rod 11 drives the mounting plate 9 to move downward, which in turn drives the pressure block 8 to move downward. At this time, with the cooperation of the support block 6, the workpiece can be fixed on one side, ensuring the stability of the workpiece during the cutting process.

[0030] Furthermore, the lower end of the scale plate 3 is fixedly connected to the processing table 1, and the upper end of the mounting plate 9 is fixedly connected to two limiting rods 10. Both limiting rods 10 are movably connected to the L-shaped plate 7 with two limiting holes inside the upper end. The mutual cooperation between the limiting rods 10 and the L-shaped plate 7 can increase the stability of the mounting plate 9 during movement.

[0031] Furthermore, the drive fixing mechanism 2 includes a drive motor 21. The lower end of the drive motor 21 is fixedly connected to the processing table 1.

The lower end of the L-shaped plate 25 is fixedly connected to the processing table 1. By starting the drive motor 21, the threaded rod 24 is rotated, which in turn drives the T-shaped plate 23 to move in the left and right directions, thereby driving the support cutting mechanism 5. The cutting mechanism 5 moves left and right, allowing for adjustment of the distance between the cutting mechanism 5 and the L-shaped plate 25 according to the required cutting length. An electric hydraulic rod 210 is fixedly connected to the upper side of the L-shaped plate 25. The lower end of the electric hydraulic rod 210 is fixedly connected to the mounting plate 28. A pressure block 27 is fixedly connected to the lower end of the mounting plate 28. A support block 26 is correspondingly provided on the lower side of the pressure block 27. The right end of the support block 26 is fixedly connected to the L-shaped plate 25. The T-shaped plate 23 is movably connected to two L-shaped rods 22 through two circular holes inside it. The lower ends of the L-shaped rods 22 are fixedly connected to the processing table 1, and the right ends of the two L-shaped rods 22 are fixedly connected to the L-shaped plate 25. Two limiting rods 29 are fixedly connected to the upper end of the mounting plate 28. Both limiting rods 29 are movably connected to the L-shaped plate 25, which has two limiting holes inside its upper end. The L-shaped plate 25 restricts the right end of the workpiece to be processed. Through the cooperation between the L-shaped plate 25 and the support cutting mechanism 5, a quantitative cutting process of the workpiece can be achieved, ensuring the consistency of the cutting length during multiple cutting processes. The electric hydraulic rod 210 drives the mounting plate 28 downward, which, with the cooperation of the pressure block 27 and the support block 26, fixes the right end of the workpiece during the cutting process, further ensuring the stability of the workpiece during processing. After the workpiece is cut, it provides support for the cut-off workpiece, making it easy for the operator to pick it up. The L-shaped rod 22 restricts the movement direction of the T-shaped plate 23, and the cooperation between the limiting rod 29 and the L-shaped plate 25 increases the stability of the mounting plate 28 during movement.

[0032] The supporting cutting mechanism 5 includes a concave fixed frame 51. The lower end of the concave fixed frame 51 is fixedly connected to the T-shaped plate 23. Two support blocks 52 are fixedly connected to the bottom surface inside the concave fixed frame 51. Two electric hydraulic rods 511 are fixedly connected to the upper surface inside the concave fixed frame 51. The lower ends of the two electric hydraulic rods 511 are fixedly connected to the mounting plate 58. A dual-axis motor 510 is fixedly connected to the upper end of the mounting plate 58. The dual-axis motor 510 is fixedly connected to two sprockets 59 via two output shafts. The two sprockets 59 are connected to two sprockets 54 via two chains. The two sprockets 54 are fixedly connected to both ends of a rotating rod 56. A cutting blade wheel 55 is fixedly connected to the rotating rod 56. Two support plates 57 are movably connected to the rotating rod 56. The upper ends of the two support plates 57 are fixedly connected to the mounting plate 58. The mounting plate 58 is connected to the mounting plate 58 via an internal opening. Two circular holes are movably connected to two fixed rods 53. The upper and lower ends of the two fixed rods 53 are fixedly connected to the upper and lower sides of the concave fixed frame 51, respectively. The two support blocks 52 can support the workpiece during the cutting process. By starting the dual-axis motor 510, the two sprockets 59 are driven to rotate. In turn, the two sprockets 54 drive the rotating rod 56 to rotate. The rotation of the rotating rod 56 drives the cutting blade wheel 55 to rotate. At this time, the two electric hydraulic rods 511 are started to move the mounting plate 58 downward. In turn, the support plate 57 drives the rotating rod 56 and the cutting blade wheel 55 to move downward, thereby achieving the cutting process of the workpiece. The cooperation between the fixed rods 53 and the concave fixed frame 51 increases the stability of the mounting plate 58 during the movement.

[0033] The working principle of this utility model is as follows:

[0034] During the quantitative cutting of a workpiece using this device, the workpiece is placed on support block 1 (6), support block 2 (26), and two support blocks 3 (52), with the right end of the workpiece pressed against L-shaped plate 2 (25). At this point, the electric hydraulic rods 1 (11) and 2 (210) are activated to move mounting plates 9 and 2 (28) downwards, thereby moving pressure blocks 8 and 2 (27) downwards. With the cooperation of support blocks 6 and 2 (26), the workpiece is clamped and fixed on both sides. After the workpiece is fixed, the drive motor 21 is activated according to the required cutting length to rotate the threaded rod 24. This is achieved by using the L-shaped indicator arrow 4, scale plate 3, T-shaped plate 23, concave fixing bracket 51, and mounting plate 3 (58). Under the action of the support plate 57, the distance between the cutting blade wheel 55 and the right end of the workpiece is adjusted. After the adjustment is completed, the drive motor 21 is turned off and the dual-axis motor 510 is started. Then, under the action of the set sprocket 1 59, sprocket 2 54 and rotating rod 56, the cutting blade wheel 55 can be driven to rotate. During the rotation of the cutting blade wheel 55, the two electric hydraulic rods 3 511 are activated to drive the mounting plate 3 58 to move downward, which in turn drives the cutting blade wheel 55 to move downward. At this time, under the action of the set cutting blade wheel 55, the workpiece can be cut off. By repeatedly performing the above operation steps, the right end of the remaining workpiece after each cut is pressed against the L-shaped plate 25, thus achieving multiple cut-off processes for the workpiece and ensuring the consistency of the cut-off length in each cut-off process.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
