The top of the support block 10 bulges upward from both sides to the middle position into an inverted V shape, and the support blocks 10 on the two fixed rods 4 are perpendicular to each other on one side. The support blocks 10 on the two fixed rods 4 are evenly provided with anti-slip grooves on the opposite side. The support blocks 10 on the two fixed rods 4 are more prominent than the corresponding clamping blocks 9 on one side, and when the clamping blocks 9 on the two fixed rods 4 are staggered and plugged together, the support blocks 10 on the two fixed rods 4 are mutually perpendicular. The side away from the fixing rod 4 can be spliced ​​into a right angle, the clamp block 9 and the corresponding slider 8 are provided with a strip-shaped plug hole 11 in the same position along the two sides, the plug hole 11 is inserted with a strip plate 12, and the strip plate 12 is located at the top of the fixing rod 4, the top of the strip plate 12 is flush with the top surface of the cover plate 3, and the two sides of the strip plate 12 are respectively fixedly connected to the inner walls of the two sides of the installation hole, the front side of the installation box 2 is provided with a positioning component 13, the top of the cover plate 3 is provided with a pressing component 14, and a cutting component 15 is provided between the positioning component 13 and the front side of the installation box 2;

[0029] The cutting assembly 15 includes a cutting machine 151, which is located at the top between the support table 131 and the installation box 2. A mounting frame 152 is provided on one side of the cutting machine 151. The mounting frame 152 is fixedly installed on the top of the cutting table 1. The cutting machine 151 is installed on the mounting frame 152, and the cutting machine 151 can deflect up and down in the vertical direction.

[0030] The clamping assembly 14 includes an electric push rod 141, the top of which is fixedly connected to a U-shaped frame 142, the bottoms of both ends of the U-shaped frame 142 are fixedly connected to the top of the cover plate 3, the bottom of the electric push rod 141 is horizontally fixedly connected to a pressing plate 143, and the pressing plate 143 is parallel to the fixing rod 4, a V-shaped slot 144 is provided at the bottom of the pressing plate 143, the front and rear sides of the slot 144 are respectively connected to the front and rear sides of the pressing plate 143, and the opening angle of the slot 144 is ninety degrees, the bottom of the pressing plate 143 is fixedly connected to a protective rubber strip 21 matching the length of the pressing plate 143 near both sides, and anti-slip protrusions 22 are evenly distributed in the slot 144 at the bottom of the pressing plate 143;

[0031] When fixing the angle iron, when the side length of the angle iron is close to the side length of the support block 10 close to the slider 8, the drive motor 6 can be started to drive the two drive rods 5 to rotate synchronously through the transmission belt 7, and as the drive rod 5 rotates, the two fixed rods 4 can move in opposite directions, and in this process, the clamping blocks 9 on the two fixed rods 4 can approach each other. When the multiple clamping blocks 9 on the two fixed rods 4 are staggered and plugged together, the separated sides of the support blocks 10 on the two fixed rods 4 can be spliced ​​into a right angle. At this time, the angle iron is placed with the opening facing downward on the top of the multiple support blocks 10, and the two right-angled sides of the angle iron can be supported by the separated sides of the support blocks 10 on the two fixed rods 4 respectively; and when the side length of the angle iron is greater than the side length of the support block 10 close to the slider 8, When the lengths are similar, the distance between the two fixing rods 4 can be appropriately increased, and the distance between the support blocks 10 on the two fixing rods 4 can be ensured to be smaller than the opening width of the angle iron. At this time, the angle iron is placed with the opening facing downward on the top of the multiple support blocks 10 on the two fixing rods 4. At this time, the two right-angled sides of the angle iron can also be supported by the separated sides of the support blocks 10 on the two fixing rods 4, and the connection between the two right-angled sides of the angle iron can be opposite to the groove 144 at the bottom of the pressing plate 143. As the electric push rod 141 gradually extends, the pressing plate 143 gradually approaches the angle iron. When the groove 144 at the bottom of the pressing plate 143 contacts the top of the angle iron, the groove 144 at the bottom of the pressing plate 143 can cooperate with the multiple support blocks 10 on the two fixing rods 4 to realize the clamping operation of the angle irons with different side lengths.

[0032] When fixing the metal pipe, when the metal pipe is placed between the two fixing rods 4, since the opposite sides of the support blocks 10 on the two fixing rods 4 can form a "V-shaped groove", when the metal pipe is placed on the opposite sides of the multiple support blocks 10 on the two fixing rods 4, the metal pipe can be centrally restricted by the multiple support blocks 10, and then when the electric push rod 141 is extended, the pressing plate 143 can gradually approach the top of the metal pipe, and when the clamping groove 144 at the bottom of the pressing plate 143 contacts the top of the metal pipe, the clamping groove 144 at the bottom of the pressing plate 143 can cooperate with the "V-shaped groove" formed by the multiple support blocks 10 to achieve the clamping operation of the metal pipe;

[0033] When clamping some metal strips or metal plates, the driving motor 6 is started, and the two fixing rods 4 are driven to move in the direction of separation through the driving rod 5. As the two fixing rods 4 move, the distance between the clamping blocks 9 on the two fixing rods 4 increases accordingly. When the distance is greater than the width of the metal strip or metal plate, the metal strip or metal plate is placed between the clamping blocks 9 on the two fixing rods 4, and the bottom of the metal strip or metal plate can be supported by multiple strip plates 12 and the cover plate 3. Then the driving motor 6 is rotated in the opposite direction, thereby driving the two fixing rods 4 to move in opposite directions, and then driving the clamping blocks 9 on the two fixing rods 4 to clamp the metal strip or metal plate in the center. Finally, the electric push rod 141 is started, so that it drives the pressing plate 143 to press the top of the metal strip or metal plate, and the protective rubber strip 21 at the bottom of the pressing plate 143 can protect the surface of the metal strip or metal plate to avoid leaving indentations on the surface of the metal plate or metal strip.

[0034] Compared with the existing positioning devices, the present invention can realize the clamping operation of various metal parts such as angle irons, metal pipes, metal bars and metal plates of different specifications through the mutual cooperation of the support block 10 and the clamping block 9 on the two fixed rods 4, reducing the steps of replacing the clamps, improving the convenience of fixing and clamping different metal parts, and improving the cutting efficiency of metal parts.

[0035] like Figure 1 and Figure 3As shown, the positioning assembly 13 includes a support table 131, which is fixedly installed on the top of the cutting table 1, and a groove is opened on the top of the support table 131, in which a movable plate 132 is slidably installed, and a support plate 133 is horizontally fixedly connected to the top of the movable plate 132, and the top of the support plate 133 is flush with the top of the cover plate 3, and a positioning plate 134 is vertically fixedly connected to the top of the support plate 133, and a first adjusting rod 135 is inserted and penetrated by a vertical thread along the front and rear directions of the movable plate 132, and the front end of the first adjusting rod 135 is rotatably inserted and penetrated into the front side of the support table 131, and the rear end of the first adjusting rod 135 is vertically rotatably connected to the rear side groove wall of the groove, and a vertical pointer 23 is fixedly connected to one side of the support plate 133, and scales 24 are evenly arranged on the side of the support table 131 at a position opposite to the pointer 23;

[0036] By providing the positioning assembly 13, when fixing the metal part, the distance of the positioning plate 134 can be adjusted according to the cutting length requirement. When adjusting the positioning plate 134, the first adjusting rod 135 can be rotated to drive the support plate 133 and the positioning plate 134 on its top to move through the movable plate 132, and the moving distance can be determined according to the pointer 23 and the scale 24. When the distance of the positioning plate 134 is adjusted, before fixing the metal part, the end of the metal part close to the positioning plate 134 is first made to fit tightly with the positioning plate 134, and then the metal part is fixed. When the fixed metal part is cut by the cutting machine 151, as the metal part is cut off, the distance from the cutoff point to the positioning plate 134 is the length of the specified metal part, and each subsequent cutting only needs to keep the metal part and the positioning plate 134 close and then fix them. The size of the metal part cut out is the specified length, which avoids repeated measurements when cutting the metal part and improves the cutting efficiency.

[0037] like Figure 5 and Figure 6 As shown, a same rectangular fixing ring 16 is fixedly connected between the bottoms of a plurality of sliders 8 located on the same fixing rod 4, a plug plate 17 is slidably inserted between two of the fixing rings 16, and the top of the plug plate 17 near the four corners is vertically slidably penetrated and inserted with a limit rod 18, and the bottom end of the limit rod 18 is vertically fixedly connected to the bottom inner wall of the installation box 2, and a second adjusting rod 19 is vertically rotatably connected at the bottom center of the plug plate 17, and the second adjusting rod 19 is threadedly inserted into the bottom box wall of the installation box 2, a through hole is penetrated at the position of the top of the cutting table 1 opposite to the second adjusting rod 19, and the second adjusting rod 19 is inserted through the through hole, and a notch 20 is provided on the side of the clamping block 9 away from the slider 8 connected thereto, and the height of the notch 20 matches the height of the slider 8, and the top inner wall of the notch 20 is inclined upward from bottom to top in the direction away from the slider 8;

[0038] When fixing some angle irons with longer sides, the second adjusting rod 19 can be rotated to drive the plug plate 17 to move upward, and as the plug plate 17 moves upward, the clamping block 9 on the two fixing rods 4 can also move upward under the support force of the plug plate 17 on the slider 8, and as the clamping block 9 moves upward, the distance between the support block 10 on the top of the clamping block 9 and the cover plate 3 also increases, so that when the angle iron with longer sides is placed on the top of the multiple support blocks 10 on the two fixing rods 4, the bottom edge of the angle iron will not contact the top of the cover plate 3 due to being too long, so that when the pressing plate 143 is pressed on the top of the angle iron, the angle iron can be clamped under the cooperation of the pressing plate 143 and the multiple support blocks 10 on the two fixing rods 4, thereby meeting the clamping requirements of the angle iron with longer sides;

[0039] When clamping some metal pipes with larger diameters, the distance between the two fixing rods 4 can be adjusted by the driving rod 5, so that the distance between the clamping blocks 9 on the two fixing rods 4 can be increased, and then the clamping blocks 9 can be moved upward by rotating the second adjusting rod 19. When the top inner wall of the notch 20 is higher than the radius of the metal pipe, the metal pipe to be clamped is placed between the two fixing rods 4, and then the two fixing rods 4 are driven closer to each other by the driving rod 5. When the clamping blocks 9 on the two fixing rods 4 contact both sides of the metal pipe, the clamping blocks 9 on the two fixing rods 4 can clamp the metal pipe through the notch 20, and the top inner wall of the notch 20 can limit the metal pipe, so that the metal pipe can be clamped stably.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
