Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a positioning mechanism for cutting metal raw materials. Background Technology

[0002] Machining can be divided into cutting machining and pressure machining according to the difference in processing methods. Cutting machining is to cut the workpiece with a cutting tool, thereby changing the shape and size of the workpiece; while pressure machining is to change the shape or properties of the workpiece by applying pressure.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN218555780U, authorized on March 3, 2023, discloses a metal plate cutting device with a positioning mechanism. The device includes a base for placing the metal plate, a cutting mechanism positioned above the base for cutting the metal plate, clamping components fixedly mounted at both ends of the base, a crossbeam fixedly mounted on one side of the base, a slot in the middle of the base, a baffle plate connected to the side of the base away from the crossbeam, and sliding grooves at the top of the base corresponding to the two ends of the baffle plate. Stops slidably connected to the sliding grooves are fixedly mounted at both ends of the baffle plate. This invention, through the arrangement of the base, clamping plate, crossbeam, baffle plate, and stops, can fix the position of the metal plate placed on the base, ensuring the metal plate is securely installed and will not easily loosen, thus facilitating the cutting of the metal plate, further improving cutting efficiency and processing quality, and thereby enhancing the applicability of the metal plate cutting device.

[0004] However, the device still has the following drawbacks: Although it can fix the metal plate, due to the fixed position of the fixing mechanism, the device may only be applicable to metal plates of specific sizes or specifications. When it is necessary to cut metal plates of different sizes or shapes, it may be necessary to replace the entire positioning mechanism or make tedious manual adjustments, which greatly reduces the applicability and flexibility of the device. If the fixing mechanism cannot be precisely adjusted according to the specifications of the metal plate, inaccurate positioning may occur during the cutting process, which may lead to problems such as uneven cutting edges and dimensional deviations, thereby affecting the cutting quality and subsequent processing effects.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model embodiment provides a positioning mechanism for cutting metal raw materials, including a base plate 1, exemplarily, such as... Figures 1-3 As shown.

[0024] The base plate 1 has a placement plate 2 on both sides of its top. The front side of the top of the base plate 1 has a first driving mechanism 3. The top of the placement plate 2 has two square blocks 4. The top of the square blocks 4 is fixedly connected to a first connecting piece 5. The inner cavity of the first connecting piece 5 is rotatably connected to a rotating block 6. One side of the rotating block 6 is fixedly connected to a second fixing block 7. The top of the rotating block 6 is fixedly connected to a long rod 8. The surface of the long rod 8 is slidably connected to a sleeve block 9. The top end of the long rod 8 is fixedly connected to a second protrusion 12. The surface of the long rod 8 is fitted with a spring 10. The two ends of the spring 10 are fixedly connected to the sleeve block 9 and the second protrusion 12, respectively. The top side of the square block 4 has a second driving mechanism 11.

[0025] The first drive mechanism 3 includes a double-axis threaded rod 31 disposed on the front side of the top of the base plate 1, such as Figures 1-3 As shown.

[0026] The surface of the dual-axis threaded rod 31 is fitted with a first fixing block 32, the bottom of the first fixing block 32 is fixedly connected to the base plate 1, one end of the dual-axis threaded rod 31 is rotatably connected to a first protrusion 33, the bottom of the first protrusion 33 is fixedly connected to the base plate 1, the surface of the dual-axis threaded rod 31 is threadedly connected to two threaded blocks 34, one side of the threaded block 34 is fixedly connected to the placement plate 2, and the right side of the top of the base plate 1 is fixedly connected to a motor 35, the output end of the motor 35 is connected to the dual-axis threaded rod 31 for transmission.

[0027] Specifically, the first driving mechanism 3 moves the placement plate 2, thereby driving the second fixing block 7 to move. When the two second fixing blocks 7 come into contact with the metal raw material, their positions are fixed, making them suitable for metal raw materials of different lengths.

[0028] The second drive mechanism 11 includes a second connector 111 fixedly connected to the top of the square block 4, such as... Figures 1-3 As shown.

[0029] An electric telescopic rod 112 is rotatably connected to the inner cavity of the second connector 111. A first adjusting block 113 is rotatably connected to the surface of the sleeve block 9. The output end of the electric telescopic rod 112 is connected to the first adjusting block 113. A second adjusting block 114 is rotatably connected to the surface of the first adjusting block 113. A first connecting rod 115 is fixedly connected to one side of the second adjusting block 114. A concave block 116 is rotatably connected to the surface of the first connecting rod 115. A second connecting rod 117 is rotatably connected to the surface of the second protrusion 12. One end of the second adjusting block 114 is fixedly connected to the concave block 116.

[0030] Specifically, the second drive mechanism 11 is designed to adjust the angle of the second connecting rod 117, thereby enabling the second connecting rod 117 to fix metal materials of different thicknesses and ensuring that the positioning mechanism always maintains close contact with the metal material.

[0031] A mounting base 13 is fitted onto the surface of the motor 35, and a bolt is threaded onto the top of the mounting base 13. The base plate 1 is threadedly connected to the motor 35. Figures 1-3 As shown.

[0032] A guide rod 14 is fixedly connected to the rear side of the top of the base plate 1. A guide block 15 is sleeved on the surface of the guide rod 14. One side of the guide block 15 is fixedly connected to the placement plate 2. The sleeve 9 and the spring 10 form a telescopic structure. The maximum moving distance of the sleeve 9 is equal to the deformation of the spring 10. A through groove 16 is opened on the top of the base plate 1. The through groove 16 is rectangular in shape.

[0033] Specifically, the mounting base 13 and bolts work together to fix the motor 35, while also facilitating disassembly and maintenance by the user. The guide rod 14 and guide block 15 work together to guide the placement plate 2, improving the stability of the placement plate 2 during movement.

[0034] The working principle of the positioning mechanism for cutting metal raw materials proposed in this embodiment of the invention is as follows:

[0035] When the device is in use, the metal raw material is placed on the top of the base plate 1. Then, the motor 35 is started. The output end of the motor 35 drives the double-axis threaded rod 31 to rotate. When the double-axis threaded rod 31 rotates, it drives the two threaded blocks 34 to move relative to each other. The threaded blocks 34 drive the placement plate 2 to move. The placement plate 2 drives the second drive mechanism 11 to move through the square block 4. As the two square blocks 4 approach each other, the two second fixed blocks 7 will come into contact with the metal raw material.

[0036] Furthermore, by activating the electric telescopic rod 112, the output end of the electric telescopic rod 112 drives the first adjusting block 113 to move. The first adjusting block 113 drives the rotating block 6 to rotate in the inner cavity of the first connecting piece 5 through the sleeve block 9. The rotating block 6 drives the second fixed block 7 to move, so that one side of the second fixed block 7 makes close contact with the metal raw material.

[0037] Furthermore, when the first adjusting block 113 moves, it causes the sleeve block 9 to slide upward on the surface of the long rod 8. When the sleeve block 9 slides, it causes the spring 10 to be compressed. When the first adjusting block 113 moves, it causes the second adjusting block 114 to move. The second adjusting block 114 causes the concave block 116 to move through the first connecting rod 115. The concave block 116 causes the second connecting rod 117 to make an arc-shaped movement around the second protrusion 12, so that one end of the second connecting rod 117 is in close contact with the top of the metal material, thereby achieving the function of positioning the metal material.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
