Description

Technical Field

[0001] The utility model relates to the technical field of the inner hole size test of a porous packaging tube, in particular to a quick test fixture for the inner hole size of a porous packaging tube. Background Technique

[0002] For the packaging tube used for a drill bit, which has 20 drill bit positioning holes with different depths and diameters, during its design and development and mass production, inspectors need to conduct size and function tests on the 20 holes of this product one by one to evaluate whether it meets the requirements. However, for a long time, corresponding drill bits have been used to test the positioning holes one by one, and this method has the following disadvantages:

[0003] 1. Since the number of holes in this product is too large, using corresponding drill bits to test one by one results in too low test efficiency;

[0004] 2. Multiple drill bits are placed separately, making the inspection table rather messy and prone to being picked up wrongly during the test process, resulting in false inspection and misjudgment;

[0005] 3. When a person holds a drill bit for detection, in order to ensure the monitoring accuracy, the diameter gap between the drill bit and the hole diameter of the packaging tube will be very small. Once there is any deviation, there may be a risk of damaging the inner wall of the packaging tube. Content of the Utility Model

[0029] The working principle of the present utility model is as follows:

[0030] When rapid testing of the inner hole size of the porous packaging tube is required, the porous packaging tube to be tested is passed through the detection hole 47, and then the motor 461 is started through the single-chip microcomputer 3. The motor 461 drives the rack 465 to slide towards each other in the dovetail chute, thereby clamping the porous packaging tube. Since the detection hole 47 corresponds to the electric push rod 44 in the up and down positions, according to the inner hole size of the porous packaging tube to be detected, the electric motor 451 is started through the single-chip microcomputer 3. The electric motor 451 drives the turntable 41 to rotate. Since there are 20 drill bits 42 and the angular spacing between each drill bit 42 is 18 degrees, the required drill bits 42 are determined according to the inner hole size of the porous packaging tube to be detected, and then the angle of rotation of the turntable 41 is determined. When the turntable 41 rotates to the required angle, the angle sensor 5 will feedback the signal to the single-chip microcomputer 3. The single-chip microcomputer 3 controls the electric motor 451 to stop running, and then the electric push rod 44 is controlled through the single-chip microcomputer 3. The telescopic end of the electric push rod 44 extends downward to squeeze the upper end of the drill bit 42, causing the drill bit 42 to move downward and compress the spring 43 to contract, and the drill bit 42 is inserted into the porous packaging tube for size detection;

[0031] The drill bits 42 are uniformly fixed at the lower end of the turntable 41, and the corresponding drill bits 42 are adjusted according to the size of the packaging tube to be detected for use. While preventing the detection table from being messy, it also avoids the risk of detection errors caused by taking the wrong drill bit 42. With the assistance of the rack 465 for clamping, the packaging tube and the drill bit 42 are more accurately opposed, avoiding damage to the inner wall of the packaging tube.

[0032] It should be noted that in the above embodiments, the single-chip microcomputer 3 can be selected from the 51 series single-chip microcomputers, the electric push rod 44 can be selected as JC35FA20A, the motor 461 can be selected as CM21-ER16.ER20, the electric motor 451 can be selected as KS-4632, and the angle sensor 5 can be selected as MZK.
