Description

Technical Field

[0001] The utility model relates to the technical field of performance detection, in particular to a diamond drill bit performance detection device. Background Art

[0002] Diamond drill bits are the main tool for underground drilling. The drilling principle is to use the ultra-hardness of the diamond particles in the working layer of the drill bit to gradually carve and grind the rock, hard soil or gravel under the ground to achieve step-by-step drilling.

[0003] Generally, the drilling on the engineering site requires the diamond drill bit to have a fast speed, a large footage, a long life, a stable operation, few underground accidents, and good wellbore quality, etc. This requires that the diamond must have high strength, high wear resistance and impact resistance before production and use. However, in the prior art, when the diamond drill bit is processed and tested, the drill bit is installed on a rotating rod, and the drill bit is manually held and pressed down by the pressure rod so that the drill bit can be lowered, and the test plate is drilled through by the drill bit, and the time for different drill bits to drill through the test plate is recorded. The shorter the time, the faster the drill bit drills and the better the performance. However, when the staff manually controls the drill bit to descend for drilling testing, the staff may press different drill bits with different strengths. When the staff's hands are tired, they cannot better control the pressing strength, and the drilling speed of the drill bit will also be different due to different pressing strengths, resulting in inaccurate test results. Therefore, a diamond drill bit performance testing device is needed. Utility Model Content

The hydraulic cylinder 5 is fixedly installed on the mounting frame 4, and the two groups of guide rods 6 are slidably connected to the mounting frame 4. The hydraulic cylinder 5 outputs The output end and the two groups of guide rods 6 are connected to the top of the movable plate 7, the four groups of slide rods 9 are slidably connected to the movable plate 7, the four groups of connecting plates 10 are respectively connected to the top of the four groups of slide rods 9, the bottom ends of the four groups of slide rods 9 are connected to the mounting plate 8, the four groups of springs 11 are respectively fitted to the four groups of slide rods 9, the tops of the four groups of springs 11 are connected to the movable plate 7, the bottom ends of the four groups of springs 11 are connected to the mounting plate 8, the motor 12 is fixedly installed at the bottom of the mounting plate 8, the drive shaft 13 is connected to the output end of the motor 12, and the drill body 1 is installed at the bottom of the drive shaft 13; The utility model also includes a mounting assembly, on which the detection plate 2 is mounted; the detection plate 2 is mounted on the mounting assembly, the drill body 1 is mounted on the driving shaft 13, the hydraulic cylinder 5 is started to push the movable plate 7 down, and the drill body 1 is driven to descend at the same time, when the drill body 1 contacts the top of the detection plate 2, the hydraulic cylinder 5 continues to descend and pushes the movable plate 7 down, so that the movable plate 7 compresses the spring 11, and the hydraulic cylinder 5 is stopped when the movable plate 7 descends to the specified position, at which time the drill body 1 is tightly against the detection plate 2, the motor 12 is started to drive the driving shaft 13 to rotate, and the drill body 1 is driven to drill the detection plate 2, and the time when the drill body 1 starts drilling and drills through the detection plate 2 is recorded. Since the position of the spring 11 is fixed by the movable plate 7 when the drill body 1 of the same model is tested, the same depth of pressing force when the drill body 1 of the same model drills the detection plate 2 is the same, thereby providing a diamond drill performance testing device that can reduce the influence of the pressing force on the drill drilling test, and can improve the accuracy of the test result.

[0022] See also Figure 1-Figure 3 The installation assembly includes two groups of support plates 14, both groups of support plates 14 are fixedly installed on the base plate 3, the inner ends of the two groups of support plates 14 are provided with placement grooves, the tops of the two groups of placement grooves are provided with two groups of fastening screws 19, and the four groups of fastening screws 19 are tightly attached to the detection plate 2; the detection plate 2 is placed in the placement groove, and the detection plate 2 can be fixed by tightening the fastening screws 19.
