Description

Technical Field

[0001] The utility model relates to the technical field of flaw detection equipment, in particular to a watchdog mechanism for the production of straight rod off-line flaw detection equipment. Background Art

[0002] The application of flaw detectors is very extensive. For example, they use the reflection of ultrasound to measure distance, use high-power ultrasonic vibration to remove scale attached to boilers, and use high-energy ultrasound to make an "ultrasonic knife" to eliminate and smash cancer and stones in the human body. The flaw detector uses the reflection effect of ultrasound and its strong penetration and linear propagation to carry out detection, which is also one of the major application areas. The detection application of flaw detectors mainly includes the detection of various materials in industry and the detection and diagnosis of the human body in medicine. Through it, people can detect whether there are bubbles, scars, cracks and other defects in industrial materials such as metals, and can detect whether the soft tissues and blood flow of people's bodies are normal.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Example 1

[0033] Reference Figure 1-7 , which is the first embodiment of the utility model, provides a watchdog mechanism for production of straight rod offline flaw detection equipment, including a feeding roller 1 and a base 2 arranged at the four corners of the bottom end of the feeding roller 1, a straight rod 4 is arranged at the upper end of the feeding roller 1, an adjustment plate 6 is arranged at the discharge end of the feeding roller 1, and a mounting assembly 8 is inserted at the middle end of the adjustment plate 6, and a first guide nozzle 11 and a second guide nozzle 12 are respectively inserted at the front and rear ends of the inner wall of the middle end of the mounting assembly 8;

[0034] The first guide nozzle 11 includes a first retaining cylinder 111 inserted at the front side of the inner wall of the middle end of the mounting assembly 8, and the first retaining cylinder 111 has a first arc groove 112 and a first circular groove 113 at both ends of the inner wall, the first arc groove 112 is formed in a truncated cone shape, and the first circular groove 113 is formed in a cylindrical shape;

[0035] The second guide nozzle 12 includes a second retaining cylinder 121 inserted and arranged on the rear side of the inner wall of the middle end of the mounting assembly 8, and the second retaining cylinder 121 has a second arc groove 122 and a second circular groove 123 at both ends, the second arc groove 122 is formed in a truncated cone shape, the second circular groove 123 is formed in a cylindrical shape, the radius of the first circular groove 113 is greater than the radius of the second circular groove 123, the volume formed by the first arc groove 112 is greater than the volume formed by the second arc groove 122, and the arc-shaped apertures of the first arc groove 112, the first circular groove 113, the second arc groove 122, and the second circular groove 123 decrease in sequence from the outside to the inside.

[0036] When more than two straight rods 4 pass through the feeding roller 1 and reach the first baffle 111, multiple groups of straight rods 4 pass through the first arc groove 112 opened on the inner wall of the first baffle 111. Through the screening of the first arc groove 112, most of the straight rods 4 are intercepted on the arc surface of the first arc groove 112, and then the straight rods 4 that are not intercepted pass through the first circular groove 113 and enter the second arc groove 122, and then only one of them enters the second circular groove 123. After multi-level interception, one of the multiple groups of straight rods 4 passes through the first guide nozzle 11 and the second guide nozzle 12, so as to facilitate subsequent detection. When there are more than one material on the feeding roller 1, they cannot pass through the guide nozzle, which completely solves the problem of multiple materials entering the flaw detection device at the same time. The first guide nozzle 11 and the second guide nozzle 12 of the above-mentioned device will cooperate to intercept the material, which is a "watchdog" device.

[0037] Example 2

[0038] Reference Figure 1-7 , which is the second embodiment of the utility model, which is different from the first embodiment in that: baffles 3 are arranged on both sides of the front and rear ends of the upper end of the feeding roller 1, and two symmetrical sets of fixing plates 5 are arranged on the outer wall of the side of the adjusting plate 6 close to the feeding roller 1, and bolts are threadedly inserted at the upper ends of the fixing plates 5, and threaded holes matching with the bolts are opened at the upper ends of the baffles 3;

[0039] The mounting assembly 8 includes a mounting block 81 disposed at the middle end of the adjusting plate 6, and two symmetrical sets of adjusting grooves 82 are provided at the left and right ends of the mounting block 81, and adjusting rails 7 matching the adjusting grooves 82 are provided at the left and right ends of the inner wall of the adjusting plate 6;

[0040] The first guide nozzle 11 also includes a wedge block 114 arranged at the front end of the upper surface of 111, and a limiting groove 115 is provided on the upper surface of the first stopper 111. The mounting assembly 8 also includes a cavity 86 provided on the inner wall of the upper end of the mounting block 81, and a limiting rod 85 is slidably inserted in the middle of the cavity 86, and a slope matching the wedge block 114 is provided at the lower end of the limiting rod 85. A sliding sleeve 87 is fixedly sleeved on the outer wall of the limiting rod 85, and the sliding sleeve 87 is slidably connected to the inner wall of the cavity 86. A spring 88 is sleeved on the outer wall of the limiting rod 85, and the upper and lower ends of the spring 88 are respectively fixedly connected to the cavity 86 and the sliding sleeve 87;

[0041] The mounting assembly 8 further includes a positioning groove 84 formed on the front side of the lower end of the inner wall of the mounting block 81, and the first guide nozzle 11 further includes a positioning rod 116 disposed on the front end of the lower surface of the first retaining cylinder 111, and the positioning rod 116 can be slidably inserted into the inner wall of the positioning groove 84;

[0042] The mounting assembly 8 further includes a stopper 83 disposed on the inner wall of the front end of the mounting block 81, and the stopper 83 is configured in a circular ring shape;

[0043] A ball screw sleeve 9 is fixedly arranged on one side of the outer wall of the mounting block 81 , and a ball screw 10 is movably inserted in the middle end of the ball screw sleeve 9 , and the upper and lower ends of the adjusting plate 6 and the ball screw 10 are rotatably connected.

[0044] Since different types of straight rods 4 have different diameters, in order to facilitate flaw detection of straight rods 4 with different diameters, it is necessary to quickly replace the first guide nozzle 11 and the second guide nozzle 12 to adapt to different straight rods 4. When the guide nozzle needs to be installed, the outer wall of the second stopper cylinder 121 can be slid along the inner wall of the mounting block 81 until the second stopper cylinder 121 contacts the stopper block 83 and cannot move further. The setting of the stopper block 83 can prevent the first stopper cylinder 111 from providing a thrust when installing the first stopper cylinder 111, causing the second stopper cylinder 121 to slide out of the inner wall of the mounting block 81. Then, the positioning rod 116 provided at the lower end of the first stopper cylinder 111 slides through the positioning groove 84 provided at the lower end of the mounting block 81, and the first stopper cylinder 111 is slidably inserted into the mounting block 81. When the first stopper 111 enters the installation block 81, the wedge block 114 and the inclined surface of the lower end of the limit rod 85 cooperate with each other, and the wedge block 114 drives the limit rod 85 to slide upward along the cavity 86, and at the same time drives the sliding sleeve 87 to compress the spring 88. After the stopper 114 leaves the limit rod 85, the lower end of the limit rod 85 slides along the upper end surface of the first stopper 111 until the limit rod 85 reaches the upper end of the limit groove 115, and then under the reverse elastic force of the spring 88, the sliding sleeve 87 is driven to slide downward along the cavity 86, thereby driving the limit rod 85 to be inserted into the limit groove 115, completing the installation of the first stopper 111. When the first stopper 111 needs to be removed, the limit rod 85 can be lifted upward to quickly pull out the first stopper 111 for replacement.

[0045] When the center line of the stall changes, the ball screw 10 can be rotated to drive the ball screw sleeve 9 to slide up and down along the ball screw 10. Adjustment grooves 82 are provided on the left and right ends of the mounting block 81, and adjustment rails 7 matching the adjustment grooves 82 are provided on the left and right ends of the inner wall of the adjustment plate 6. Therefore, the mounting block 81 can slide up and down along the adjustment rails 7, so that the center line can be easily adjusted to adapt to changes in different center lines.

[0046] The remaining structures are the same as those of Example 1.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
