[0002] Rod refers to a long strip of metal or non-metallic material. Rods are widely used in various industries and fields, such as machinery manufacturing, construction, automobiles, aerospace, electronics, furniture manufacturing, etc.

[0003] In order to ensure that the shape and surface quality of the rods meet the standards, it is necessary to inspect the rods after production to promptly detect defects in the rods, such as cracks, dents, etc., to prevent these defects from affecting the performance of the final product, thereby ensuring the quality of the final product.

[0004] The rod needs to remain stable during the measurement process. External forces applied during the measurement process, such as pressure during manual measurement, can easily cause the position of the rod to change, which can easily cause errors during detection. Therefore, the rod needs to be positioned and fixed, and the existing positioning structure is relatively complicated to operate. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1 A positioning device based on rod detection includes a base 1 and a support leg 2 fixedly connected to the bottom end of the base 1. A positioning component 3 for fixing the rod is arranged above the base 1.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example 1: Please refer to Figure 1-Figure 4The positioning assembly 3 includes a transverse plate 31, a spring 32 fixedly connected to the top of the transverse plate 31, a support plate 33 fixedly connected to one end of the spring 32, a first support frame 34 and a second support frame 35 fixedly connected to the top of the transverse plate 31, a movable block 36 and a connecting rod 38 arranged between the first support frame 34 and the second support frame 35, a positioning plate 37 fixedly connected to one side of the movable block 36, and a rotating shaft 39 rotatably connected to the outer surface of the movable block 36. The outer surfaces of the first support frame 34 and the second support frame 35 are both provided with connecting grooves, and the rotating shaft 39 rotates through the two groups of connecting grooves. The outer surface of the movable block 36 is provided with an arc groove 361, and the connecting rod 38 is correspondingly arranged to the arc groove 361. Put the rod on the top of the positioning plate 37, press the rod downward, and Under the action of 361 and connecting rod 38, the downward pressure of the rod drives the movable block 36 and the positioning plate 37 to rotate, and the positioning plate 37 rotates and opens, making it easy for the rod to slide into the top of the support plate 33. At this time, the spring 32 is compressed and drives the rod to move upward under the reaction force of the spring 32. At this time, under the action of the rotating shaft 39, the arc groove 361 and the connecting rod 38, the movable block 36 and the positioning plate 37 rotate again to restore to the initial state, thereby fixing the rod between the positioning plate 37 and the support plate 33 to prevent the rod from being offset by external force. When the rod needs to be removed, the spring 32 is pressed downward to make the gap between the positioning plate 37 and the support plate 33 continue to increase, thereby losing the fixing effect on the rod. The whole operation is convenient and quick, making the fixing and removal of the rod simple and quick.

[0025] A first friction pad 331 is fixedly connected to the top of the support plate 33, and a second friction pad 371 is fixedly connected to the outer surface of the positioning plate 37. The first friction pad 331 and the second friction pad 371 are both components made of rubber material. The rubber material has good friction properties. The first friction pad 331 and the second friction pad 371 are convenient for increasing the friction between the rod and the support plate 33 and the positioning plate 37, which helps to prevent the rod from slipping during the detection process. At the same time, the rubber material is soft in texture, thereby reducing scratches or damage to the outer surface of the rod.

[0026] The center of the arc groove 361 is located on the axis of the rotating shaft 39 , and the top of the positioning plate 37 is inclined. The inclined positioning plate 37 helps the rod to fall on the top of the supporting plate 33 better.

[0027] A groove 11 is provided at the top of the base 1, and a bidirectional threaded rod 5 is arranged inside the groove 11. The outer surface of the bidirectional threaded rod 5 is threadedly connected to a first slider 51. One end of the base 1 is fixedly connected to a motor 4. One end of the bidirectional threaded rod 5 is rotatably connected to the inner wall of the groove 11. The other end of the bidirectional threaded rod 5 rotates through the groove 11 and is fixedly connected to the output end of the motor 4. The bidirectional threaded rod 5 is driven to rotate by the motor 4. The rotation of the bidirectional threaded rod 5 drives the first slider 51 to move along the bidirectional threaded rod 5, thereby driving the positioning assembly 3 to move, so as to facilitate the adjustment of the position of the positioning assembly 3 according to the length of the rod.

[0028] The top of the first slider 51 is fixedly connected with an electric push rod 6, and the telescopic end of the electric push rod 6 is fixedly connected to the bottom end of the cross plate 31. The electric push rod 6 telescopes to drive the cross plate 31 to move up and down, thereby driving the rod to move up and down, thereby realizing the lifting and lowering of the rod, which is convenient for adjusting the height of the rod according to needs.

[0029] A sliding groove 111 is provided on the inner wall of the groove 11, and a second sliding block 511 is fixedly connected to one side of the first sliding block 51. The second sliding block 511 is slidably connected to the sliding groove 111. When the first sliding block 51 moves along the bidirectional threaded rod 5, the second sliding block 511 slides along the sliding groove 111. The sliding groove 111 and the second sliding block 511 play a guiding role, ensuring that the first sliding block 51 moves in a straight line along the bidirectional threaded rod 5, preventing deviation, and improving the accuracy of the movement of the first sliding block 51.

[0030] When in use, the bidirectional threaded rod 5 is driven to rotate by the motor 4, and the rotation of the bidirectional threaded rod 5 drives the first sliding block 51 to move along the bidirectional threaded rod 5, thereby driving the positioning assembly 3 to move, so as to facilitate the adjustment of the position of the positioning assembly 3 according to the length of the rod. After the adjustment is completed, the rod is placed on the top of the positioning plate 37 and the rod is pressed downward. Under the action of the rotating shaft 39, the arc groove 361 and the connecting rod 38, the downward pressure of the rod drives the movable block 36 and the positioning plate 37 to rotate, and the positioning plate 37 is rotated and opened, so that the rod slides into the top of the supporting plate 33. At this time, the spring 32 is compressed and drives the rod to move upward under the reaction force of the spring 32. At this time, under the action of the rotating shaft 39, the arc groove 361 and the connecting rod 38, the movable block 36 and the positioning plate 37 are rotated again to restore to the initial state, thereby fixing the rod between the positioning plate 37 and the supporting plate 33 to prevent the rod from being offset by external force. Finally, the electric push rod 6 is extended and retracted to drive the cross plate 31 to move up and down, so as to facilitate the adjustment of the height of the rod according to needs.
