DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] like Figure 1-7 As shown, the present invention provides an integrated angular displacement laser interferometer device, including a tripod bracket 1 and a laser interferometer body 2, and also includes: An angle setting structure, which is arranged on the tripod support 1 and is used to control the upward viewing angle of the laser interferometer body 2; The angle setting structure includes a first rotating shaft 3, which is rotatably connected to the tripod bracket 1, and the top of the first rotating shaft 3 is slidably matched with a first movable frame 4, and the top of the first movable frame 4 is installed with a first connecting frame 5, and the middle of the first connecting frame 5 is installed with a hollow shaft 6, and the outer surface of the hollow shaft 6 is sleeved with a second movable frame 7, and the top of the second movable frame 7 is connected to the laser interferometer body 2, and arc plates 8 are installed on both sides of the hollow shaft 6, and the interior of the hollow shaft 6 is sleeved with a second rotating shaft 9, and the outer surface of the second rotating shaft 9 is installed with a gear 10, and both ends of the second rotating shaft 9 are installed with circular arc plates 8. Ring member 11, a second connecting frame 18 is installed on the outer surface of the circular ring member 11, and a second movable plate 19 is slidably matched on the inner side of the second connecting frame 18, a fixed shaft 12 is installed inside the second movable frame 7, and a first movable plate 13 and a first spring 14 are slidably matched on the outer surface of the fixed shaft 12, both ends of the first movable plate 13 pass through the second movable frame 7 and extend to the outside of the second movable frame 7, a limiting member 15 is installed on the bottom of the first movable plate 13, a slot 20 is opened inside the first movable frame 4, and a third movable plate 22 and a third spring 23 are sleeved on the outer surface of the slot 20.
[0022] Through the cooperation between the second rotating shaft 9 and the hollow shaft 6, the circular ring member 11 can be driven to rotate, so that the second movable plate 19 moves along the surface of the arc plate 8, and through the elastic force of the first spring 14, the first movable plate 13 will be pushed to drive the limit member 15 to engage with the gear 10. At this time, the second rotating shaft 9 will be positioned, so that the second movable frame 7 and the second rotating shaft 9 rotate synchronously, so that when the second movable frame 7 rotates, the circular ring member 11 will be driven to rotate, and when the second movable plate 19 rotates to the position of the third movable plate 22, it will be blocked by the top of the third movable plate 22, thereby facilitating the control of the elevation angle of the laser interferometer body 2.
[0023] like Figure 4 , 6 As shown, the first extrusion member 16 and the second spring 17 are sleeved inside the circular ring 11. The bottom of the first extrusion member 16 is rough and passes through the circular ring 11. The first extrusion member 16 is in extrusion contact with the outer surface of the arc plate 8. When the first extrusion member 16 squeezes the arc plate 8, it can limit the circular ring 11.
[0024] Through the cooperation between the first extrusion member 16 and the circular ring member 11, the first extrusion member 16 can move along the inside of the circular ring member 11. Since the first extrusion member 16 can pass through the circular ring member 11, the circular arc plate 8 can be squeezed by the first extrusion member 16 to limit the rotation of the circular ring member 11, and then the rotation of the second movable frame 7 can be limited by the circular ring member 11, which is convenient for positioning the laser interferometer body 2.
[0025] like Figure 1 , 3As shown, four groups of movable rods 25 are sleeved inside the first movable frame 4 , an extrusion head 27 is installed on the top of the movable rod 25 , and a fourth spring 26 is sleeved on the outer surface of the movable rod 25 .
[0026] Through the design of the fourth spring 26, the extrusion head 27 can be driven to support the four corners of the bottom of the laser interferometer body 2, so that the laser interferometer body 2 remains horizontal in its initial state, and through the cooperation between the first movable frame 4 and the movable rod 25, when the laser interferometer body 2 changes its angle, the movable rod 25 can be pushed to move downward along the inner side of the first movable frame 4, so that it can adapt to different angles of the laser interferometer body 2.
[0027] like Figure 3 As shown, a second extrusion member 24 is installed at the top end of the first rotating shaft 3 , and the second extrusion member 24 is in extrusion contact with the bottom end of the third movable plate 22 , and the third spring 23 is elastically supported between the third movable plate 22 and the notch 20 .
[0028] Through the design of the third spring 23, the third movable plate 22 has good elastic reset performance. At this time, since the third spring 23 is in a compressed state, an elastic force will be applied to the third movable plate 22, thereby driving the third movable plate 22 to fit with the arc plate 8, so that it can limit the movement of the second movable plate 19. At the same time, through the cooperation between the second extrusion member 24 and the third movable plate 22, when the second extrusion member 24 is squeezed by the third movable plate 22, the two groups of third movable plates 22 can be driven to move back to each other and separate from the second movable plate 19. When the third movable plate 22 is separated from the second movable plate 19, the second movable plate 19 will release the extrusion of the first extrusion member 16, so that the elastic force of the second spring 17 will drive the first extrusion member 16 to reset, thereby being able to release the limit on the circular ring member 11.
[0029] like Figure 4 , 5 As shown in FIGS. 9 and 10 , the top end of the limiter 15 is tooth-shaped, the limiter 15 is movably engaged with the gear 10 , and the first spring 14 is elastically supported between the fixed shaft 12 and the first movable plate 13 .
[0030] The design of the first spring 14 allows the first movable plate 13 to have good elastic restoring performance. At this time, since the first spring 14 is in a compressed state, an elastic force is applied to the first movable plate 13, thereby making the fit between the stopper 15 and the gear 10 tighter.
[0031] like Figure 6 As shown, the second spring 17 is elastically supported between the first extrusion member 16 and the circular ring member 11 , the top of the first extrusion member 16 is provided with a chamfer, and the second movable plate 19 is in extrusion contact with the first extrusion member 16 .
[0032] By setting the chamfer at the top of the first extrusion member 16, when the second movable plate 19 squeezes the first extrusion member 16, the first extrusion member 16 will be driven to move to the outside of the circular ring member 11. At the same time, through the design of the second spring 17, the first extrusion member 16 has good elastic reset performance. At this time, since the second spring 17 is in a compressed state, an elastic force will be applied to the first extrusion member 16, so that when the second movable plate 19 releases the squeeze on the first extrusion member 16, it can drive the first extrusion member 16 to reset.
[0033] like Figure 7 As shown, the outer surface of the arc plate 8 is provided with scales, the second movable plate 19 is in contact with the arc plate 8, the top of the third movable plate 22 is in a "cross" shape, the left and right sides of the cross at the top of the third movable plate 22 are arc-shaped, and the ends are provided with chamfers, and the second movable plate 19 is in extrusion contact with the left and right ends of the top of the third movable plate 22.
[0034] The scale set on the outer surface of the arc plate 8 makes it easy to set the angle between the second movable plate 19 and the top of the third movable plate 22, and the angle between the second movable plate 19 and the third movable plate 22 is the angle at which the circular ring member 11 can rotate. At the same time, the circular ring member 11 and the second movable frame 7 rotate synchronously, and the laser interferometer body 2 is connected to the second movable frame 7, so that the rotation angle of the laser interferometer body 2 can be accurately controlled.
[0035] like Figure 3 As shown, the fourth spring 26 is elastically supported between the extrusion head 27 and the first movable frame 4 , the top of the extrusion head 27 is bonded with rubber, and the top end of the extrusion head 27 abuts against the bottom of the laser interferometer body 2 .
[0036] Through the design of the fourth spring 26, the extrusion head 27 has good elastic reset performance. At this time, since the fourth spring 26 is in a compressed state, an elastic force will be applied to the extrusion head 27, thereby driving the extrusion head 27 to squeeze the bottom of the laser interferometer body 2, and can support the laser interferometer body 2. At the same time, since rubber is bonded to the top of the extrusion head 27, wear on the laser interferometer body 2 can be avoided.
[0037] like Figure 7 As shown, when the circular ring 11 rotates, the top end of the third movable plate 22 can block the second movable plate 19 .
[0038] Through the design of the circular ring 11, when it rotates, it can drive the second movable plate 19 to rotate synchronously through the second connecting frame 18. When the second movable plate 19 rotates to a certain angle, it will be blocked by the third movable plate 22. Therefore, the rotation angle of the laser interferometer body 2 can be controlled by setting the maximum rotation angle of the second movable plate 19.
[0039] Working principle: First, the staff can pull the first movable plate 13 to drive the limiting member 15 to separate from the gear 10 to release the limit on the second rotating shaft 9. At the same time, through the cooperation between the second rotating shaft 9 and the hollow shaft 6, the circular ring member 11 can be used to drive the second movable plate 19 to rotate, and according to the scale set on the outer surface of the arc plate 8, the angle between the second movable plate 19 and the third movable plate 22 is controlled. Then, the first movable plate 13 is released, and the elastic force of the first spring 14 will push the first movable plate 13 to drive the limiting member 15 to engage with the gear 10 and position the second rotating shaft 9. At this time, the rotation of the second movable frame 7 will drive the second rotating shaft 9 to rotate together The second movable frame 7 rotates, so that the annular member 11 is driven to rotate when the second movable frame 7 rotates. At this time, the rotation angle of the laser interferometer body 2 can be limited. When the second movable plate 19 rotates to the position of the third movable plate 22, it will be blocked by the top of the third movable plate 22. At the same time, through the cooperation between the left and right ends of the second movable plate 19 and the third movable plate 22, the third movable plate 22 can exert a pressure on the second movable plate 19, so that the second movable plate 19 will squeeze the first extrusion member 16, and the first extrusion member 16 will squeeze the arc plate 8, thereby limiting the rotation of the second movable frame 7 and improving the stability of the laser interferometer body 2. At the same time, the staff can press the first movable frame 4 so that the first spring 14 squeezes the third movable plate 22. At this time, the third movable plate 22 will move along the outer surface of the connecting shaft 21, so that the third movable plate 22 is separated from the second movable plate 19. At this time, the second movable plate 19 will release the squeezing of the first extrusion member 16. At the same time, through the elastic force of the second spring 17, the first extrusion member 16 will be driven to reset and release the squeezing of the arc plate 8, and release the limit on the circular ring member 11. At this time, under the elastic force of the fourth spring 26, the bottom of the laser interferometer body 2 will be squeezed through the extrusion head 27, so that the laser interferometer body 2 can be quickly reset.
[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
