Technical Field

[0001] The utility model relates to the technical field of inner hole inspection equipment, in particular to an inner hole size inspection device. Background Art

[0002] The significance of workpiece inner hole detection lies in improving product quality and performance, reducing costs and risks. Workpiece inner hole detection has a wide range of application scenarios in multiple industries. By promptly discovering and repairing inner hole defects, the quality and performance of products can be effectively improved, while production costs and potential risks can be reduced. With the progress of technology and the continuous innovation of detection techniques, inner hole detection plays an increasingly important role, driving the entire industry towards higher quality and higher efficiency.

[0003] In the prior art, when detecting the inner hole size of a workpiece, the inner hole diameter is measured by an internal diameter dial gauge or an internal micrometer, and then the inner hole depth is measured. Only after the measurement can it be determined whether the inner hole size is qualified, which requires data comparison and cannot be quickly judged, reducing the efficiency. Therefore, we propose an inner hole size inspection device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an inner hole size inspection device.

Specific implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 - 4 shown, it relates to an inner hole size inspection device, including a base 1. Two L-shaped brackets 2 are installed at the bottom of the base 1. Circular holes are provided on the outer walls of the two L-shaped brackets 2. The inner walls of the two circular holes are both slidably connected with butterfly bolts 3. Threaded holes are provided at the bottom of the base 1. The inner walls of the two threaded holes are respectively threadedly connected with the outer walls of the two butterfly bolts 3. The L-shaped bracket 2 and the base 1 form a detachable installation through the butterfly bolt 3, increasing applicability. The bottoms of the two L-shaped brackets 2 are fixedly connected with the same bottom plate 4. A plurality of mounting holes 5 are provided on the outer wall of the bottom plate 4.

[0022] A warning light 7 is fixedly connected to the top of the base 1. A through hole is provided on the outer wall of the base 1. The inner wall of the through hole is threadedly connected with an adjusting rod 6. Rotating the adjusting rod 6 makes the detection head 14 extend and retract to facilitate placing the workpiece and observing. An empty slot 8 is provided on the outer wall of the adjusting rod 6. A circular ring 9 is slidably connected inside the empty slot 8. An annular scale line may be provided on the top of the circular ring 9. When the workpiece slides horizontally, observe the sliding degree of the bottom of the workpiece. A sliding rod 10 is fixedly connected inside the circular ring 9. The sliding rod 10 slides in the empty slot 8 through the circular ring 9. The cross-section of the empty slot 8 is circular.

[0023] A sliding hole is provided at the top of the adjusting rod 6. The inner wall of the sliding hole is slidably connected with the outer wall of the sliding rod 10. The sliding hole assists the sliding rod 10 to slide. A spring 12 is sleeved on the outer wall of the sliding rod 10. The bottom of the spring 12 is fixedly connected with the top of the circular ring 9. The top of the spring 12 is fixedly connected with the inner wall of the empty slot 8. The spring 12 plays an elastic reset role to ensure that the detection head 14 is located at a certain position. A touch switch 11 is fixedly connected inside the empty slot 8. The touch switch 11 is electrically connected to the warning light 7.

[0024] A detection mechanism is provided at the top of the sliding rod 10. The detection mechanism includes an annular block 15. A T-shaped threaded column 13 is fixedly connected to the top of the sliding rod 10. A detection head 14 is threadedly sleeved on the outer wall of the T-shaped threaded column 13. The detection head 14 is fixedly installed through the T-shaped threaded column 13. The detection head 14 can be replaced according to the inner hole diameters of different diameters. The outer wall of the detection head 14 is threadedly connected to the inner wall of the annular block 15. Scale lines 16 are provided on the outer walls of both the detection head 14 and the adjusting rod 6.

[0025] Working principle: When in use, pass multiple existing locking bolts through multiple mounting holes 5 to fix the base plate 4 on the workbench, which can fix the position of the whole. At the same time, the positions of the two L-shaped brackets 2 and the base 1 can be released by rotating the two wing bolts 3. The base 1 can also be operated portably. When inspecting the inner hole size of the workpiece, put the inner hole of the workpiece onto the detection head 14. When the inner hole is larger than the diameter of the detection head 14, it directly drives the detection head 14 to move downward, making the sliding rod 10 move downward to contact the touch switch 11, so that the warning light 7 lights up. When the inner hole size of the workpiece is large, it slides onto the detection head 14. Due to the generated gap, when moving horizontally, the degree of sliding after the bottom of the workpiece contacts the top of the annular block 15 can be clearly seen. At the same time, when inspecting the depth, according to the actual processed depth data, rotate the annular block 15 in advance to align with the scale line 16 on the detection head 14 to adjust the position of the annular block 15, so as to facilitate the subsequent inspection of the inner hole depth of the workpiece.
