[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] As attached Figures 1 to 4The double displacement inner hole inspection device comprises an endoscope 1, an inspection platform 2, a sliding seat 3 and a workpiece 5 to be inspected, wherein the workpiece 5 to be inspected has an inner hole. The inspection platform 2 is mounted on the sliding seat 3, and the inspection platform 2 can slide along with the sliding seat 3. The inspection platform 2 is arranged opposite to the endoscope 1. A clamping mechanism is arranged on the inspection platform 2, and the clamping mechanism can fix the workpiece 5 to be inspected on the inspection platform 2. When the inspection platform 2 slides toward the endoscope 1 along with the sliding seat 3, the mirror tube 6 of the endoscope 1 is correspondingly inserted into the inner hole of the workpiece 5 on the inspection platform 2.

[0021] The inspection table 2 is rotatably mounted on the sliding seat 3, and the rotation axis of the inspection table 2 is in the same straight line as the mirror tube 6 of the endoscope 1. After the inspection table 2 rotates, the mirror tube 6 of the endoscope 1 is still located in the inner hole of the workpiece 5 to be inspected. Since the inspection table 2 is rotatable, the inspection angle can be adjusted during the inspection of the inner hole of the workpiece 5. At a specific angle, some parts of the inner hole surface of the workpiece 5 will be clearer, so the inspection of the inner hole of the workpiece 5 will be better.

[0022] A vertical plate 7 is provided on the side of the inspection platform 2 facing the endoscope 1, and an alignment hole 8 is provided on the vertical plate 7. The alignment hole 8 is opposite to the mirror tube 6 of the endoscope 1. When the inspection platform 2 slides toward the endoscope 1 along with the sliding seat 3, the mirror tube 6 of the endoscope 1 is correspondingly inserted into the alignment hole 8. When the workpiece 5 is fixed on the inspection platform 2, the position of the mirror tube 6 can be compared through the alignment hole 8 so that the inner hole of the workpiece 5 is opposite to the alignment hole 8. In this way, the mirror tube 6 of the endoscope 1 will be inserted into the inner hole of the workpiece 5 after passing through the alignment hole 8. In one embodiment, the alignment hole 8 is a circular hole, and the mirror tube 6 is opposite to the center of the alignment hole 8. Therefore, when the workpiece 5 is fixed on the inspection platform 2, it is necessary to make the inner hole of the workpiece 5 opposite to the center of the alignment hole 8.

[0023] As attached Figure 3 As shown in FIG. 1 , the clamping mechanism includes a pressing plate 9, which is mounted on the inspection platform 2 through a vertical rod 10. The bottom end of the vertical rod 10 is fixed on the inspection platform 2, and the pressing plate 9 is mounted on the top end of the vertical rod 10. A screw hole is provided on the end of the pressing plate 9 away from the vertical rod 10, and a clamping bolt 11 that can be screwed down is provided in the screw hole. After the clamping bolt 11 moves down, the workpiece 5 can be pressed against the inspection platform.

[0024] 2. There are a card hole 12 and a quick-release hole 13 that are interconnected on the pressure plate 9, and the aperture of the quick-release hole 13 is larger than the card hole 12. The top of the vertical pole 10 is provided with an annular card slot 14, and the outer diameter of the annular card slot 14 is consistent with the aperture of the annular card slot 14. When the card hole 12 is stuck in the annular card slot 14, the pressure plate 9 is correspondingly installed on the top of the vertical pole 10. When the quick-release hole 13 is opposite to the annular card slot 14, the pressure plate 9 can be disengaged from the annular card slot 14, so that the pressure plate 9 can be removed from the vertical pole 10. After removing the pressure plate 9, it is convenient to place the workpiece 5 on the inspection table 2. A number of positioning pins 15 are also provided on the inspection table 2. The number of positioning pins 15 cooperate to limit the position of the workpiece 5 on the inspection table 2, as shown in the attached Figure 2 As shown in , with the cooperation of the positioning pin 15 and the clamping bolt 11 , the workpiece 5 to be inspected can be fixed on the inspection platform 2 .

[0025] The sliding seat 3 is provided with a rotation hole, and the end of the inspection platform 2 away from the endoscope 1 is connected with a rotation shaft 16, which extends horizontally and is correspondingly inserted into the rotation hole, so that the inspection platform 2 can rotate relative to the sliding seat 3. A locking mechanism is also provided on the rotation shaft 16, through which the inspection platform 2 can be locked at a desired angle.

[0026] As attached Figure 4 As shown in , the locking mechanism includes a locking plate 17, and the angle between the locking plate 17 and the sliding seat 3 is relatively fixed. Specifically, a limiting plate 23 is provided on one side of the locking plate 17, and a latch is provided on the locking plate 17, and a plug hole is provided on the limiting plate 23. The locking plate 17 is inserted into the plug hole of the limiting plate 23 through the latch, so that the locking plate 17 will not rotate relative to the limiting plate 23. A clamping plate 24 is connected to the limiting plate 23, and a square clamping block 25 is provided on the sliding seat 3. The clamping plate 24 is clamped on the square clamping block 25, so that the limiting plate 23 will not rotate relative to the sliding seat 3, and therefore the locking plate 17 will not rotate relative to the sliding seat 3.

[0027] The locking disk 17 is sleeved on the rotating shaft 16 through the locking hole. The locking disk 17 is also provided with a gap 18 connected to the locking hole. The locking disk 17 locks the inspection platform 2 when the gap 18 is narrowed. Specifically, a cross bar is provided in the gap 18. One end of the cross bar passes through the locking disk 17, and an adjusting handle 4 is provided at this end of the cross bar. The adjusting handle 4 is threadedly matched with the cross bar. When the adjusting handle 4 is rotated, the adjusting handle 4 can squeeze or loosen the gap 18, thereby controlling the locking disk 17 to lock or loosen the rotating shaft 16.

[0028] The sliding seat 3 is slidably mounted on the slide rail 19, and the extension direction of the slide rail 19 is consistent with the extension direction of the mirror tube 6. When the sliding seat 3 slides along the slide rail 19, it can drive the inspection platform 2 to move closer to or farther away from the endoscope 1. A lead screw 20 is installed at the bottom of the sliding seat 3, and when the lead screw 20 rotates, it drives the sliding seat 3 to slide along the slide rail 19. A push-pull handle 21 is installed on the sliding seat 3, and an adjustment hand wheel 22 is installed at one end of the lead screw 20. The lead screw 20 has a large lead, and the sliding seat 3 can be directly pushed and pulled by the push-pull handle 21 to quickly adjust the position of the sliding seat 3, and the lead screw 20 can also be rotated by adjusting the hand wheel 22 to fine-tune the position of the sliding seat 3.

[0029] One working method of the utility model is as follows: remove the pressure plate 9, place the workpiece 5 on the inspection table 2, and limit the workpiece 5 by the limit pin, then install the pressure plate 9, move the clamping bolt 11 downward, and press the workpiece 5 on the inspection table 2, and then push the sliding seat 3 toward the endoscope 1 by pushing and pulling the handle 21 or adjusting the hand wheel 22, so that the mirror tube 6 of the endoscope 1 is inserted into the inner hole of the workpiece 5 to inspect the inner surface of the workpiece 5. During the inspection, the inspection table 2 can be rotated to change the inspection angle.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
