DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment one

[0033] In order to solve the technical problems in the background art, the following multi-size metal bar clamping tool is given:

[0034] In combination with Figures 1-5 As shown in the figure, the multi-size metal bar clamping tool provided by the present application comprises a base 1, which is fixedly installed on a cutting table 2 through screws. The top of the cutting table 2 and one end thereof in the length direction are provided with a cutting mechanism 3. The base 1 is located at one side of the cutting mechanism 3. The top of the base 1 is slidably installed with a mounting frame 4 along the width direction of the cutting table 2. The base 1 is provided with a driving piece 5 acting on the mounting frame 4, which is used to make the mounting frame 4 slide or stop sliding on the base 1.

[0035] One end of the mounting frame 4 close to the cutting mechanism 3 is rotatably installed with a rotating shaft 41 in a vertical state. The top of the rotating shaft 41 is fixedly installed with a mounting block 6 abutting the top of the mounting frame 4. The mounting frame 4 is provided with an adjusting mechanism 42 acting on the rotating shaft 41, which is used to make the rotating shaft 41 rotate or stop rotating on the mounting frame 4.

[0036] The top of the mounting block 6 and along the length direction of the cutting table 2 are provided with two fixed blocks 61. The top of each of the two fixed blocks 61 is provided with a positioning mechanism 7. Two groups of the positioning mechanisms 7 are used to position the metal bar.

[0037] When sawing metal bars, two sets of positioning mechanisms 7 are used to position the metal bars, and then the cutting mechanism 3 is used to saw the metal bars, improving the stability of the metal bar sawing. When it is necessary to cut the end of the metal bar into a bevel, the adjusting mechanism 42 makes the rotating shaft 41 rotate on the mounting frame 4, which drives the mounting block 6 to rotate around the rotating shaft 41. This drives the two sets of positioning mechanisms 7 to rotate around the rotating shaft 41. At this time, when the two sets of positioning mechanisms 7 are used to position the metal bar, the metal bar can be tilted along the direction of the cutting mechanism 3. Then, the driving part 5 makes the mounting frame 4 slide on the base 1, so that the cutting point of the metal bar is located below the cutting mechanism 3. This makes it possible to make the end of the metal bar beveled when it is necessary to cut the end of the metal bar into a bevel, which is convenient for positioning the metal bar and is beneficial for the metal bar sawing operation.

[0038] Example 2

[0039] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

In use, rotating the driving rod 51 allows the mounting bracket 4 to slide on the base 1, making the operation simple.

[0041] The adjustment mechanism 42 includes a worm gear 421 coaxially fixed to the rotating shaft 41. A worm 422 meshing with the worm gear 421 is rotatably mounted on the mounting frame 4. In use, rotating the worm 422 will drive the rotating shaft 41 to rotate on the mounting frame 4 via the worm gear 421. The operation is simple. Since the meshing of the worm gear 421 and the worm 422 has a self-locking property, the worm gear 421 will not rotate when the worm 422 is not rotated, thereby fixing the position of the rotating shaft 41 and facilitating its use.

[0042] In the embodiment, the positioning mechanism 7 comprises positioning blocks 71 and bidirectional threaded rods 72, the positioning blocks 71 are symmetrically and slidingly installed on the top of the fixing blocks 61, the positioning slots 711 in V-shaped longitudinal section are formed on the sides of the two positioning blocks 71 close to each other, the bidirectional threaded rods 72 in horizontal shape are rotationally installed on the fixing blocks 61, and the bidirectional threaded rods 72 are threadedly connected with the two positioning blocks 71. When the metal bar is positioned, the metal bar is located between the two positioning blocks 71 on the two fixing blocks 61, the two bidirectional threaded rods 72 are rotated respectively, the two positioning blocks 71 on the fixing blocks 61 slide reversely and close to each other, the two positioning blocks 71 are in contact with the metal bar, and thus the metal bar is clamped and positioned by the two positioning blocks 71. The positioning slots 711 are arranged, the positioning slots 711 are in V-shaped longitudinal section, the metal bar is located in the positioning slots 711 on the sides of the two positioning blocks 71 close to each other when the metal bar is clamped and positioned, and thus the positioning effect of the metal bar is improved, and the device is suitable for clamping and positioning metal bars with different diameters and sizes.

[0043] In the embodiment, the rubber pads 712 are fixedly installed on the positioning blocks 71 in the positioning slots 711. The rubber pads 712 are arranged, the two positioning blocks 71 are in contact with the metal bar, the rubber pads 712 on the positioning blocks 71 are in contact with the metal bar when the metal bar is clamped and positioned, and thus the friction between the positioning blocks 71 and the metal bar is increased, and the clamping and positioning effect of the metal bar is improved.

[0047] In the embodiment, the indicating rod 9 abutting the top of the angle ruler 8 is fixedly installed on the end of the mounting block 6 close to the angle ruler 8. It is worth noting that the indicating rod 9 is perpendicular to the axis direction of the rotating shaft 41.
