Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a polishing and fixing device for a cylindrical mirror includes a base 1, a first inclined block 6 movably disposed on an upper surface of the base 1, and a nut 2 and a second inclined block 7 fixedly connected to the upper surface of the base 1 through a bolt. The nut 2 is connected with the screw rod 3 in a threaded mode, a first rotating handle 4 is welded at one end of the screw rod 3, a pushing block 5 is welded at the other end of the screw rod 3, and the pushing block 5 is abutted to a first inclined block 6. The clamp seat 8 is placed on the inclined plane of the first inclined block 6 and the inclined plane of the second inclined block 7, the clamp seat 8 is provided with a first through groove 801 which is through from front to back and a second through groove 802 which is through from top to bottom, a second rotating handle 9 is arranged in the first through groove 801, the second rotating handle 9 is welded with a lead screw 10 in a descending mode, two ends of the lead screw 10 are in interference fit with a base bearing 11, the base bearing 11 is fixedly connected with the clamp seat 8 through bolts, the lead screw 10 is in clearance fit with a lead screw nut 12, the lead screw nut 12 is welded with a clamping piece 13, the clamping piece 13 extends out of the second through groove 802 upwards, a clamp body 14 is welded on the upper surface of the clamp seat 8, the second rotating handle 9 is rotated to drive the lead screw 10, the lead screw nut 12 can horizontally drive the clamp body 14 to move towards the clamping piece 13 according to the lead screw transmission principle.

The second rotating handle 9 is cylindrical, and round holes are formed in the side face of the cylinder of the second rotating handle 9 and are uniformly distributed in an annular shape. A tool such as a screwdriver is inserted into the circular hole, so that the second rotary handle 9 can be conveniently rotated.

The upper surface of the base 1 is welded with a guide rail 15, the bottom of the first inclined block 6 is provided with a T-shaped groove 601, the T-shaped groove 601 is matched with the guide rail 15, and the guide rail 15 is embedded into the T-shaped groove 601 and is in sliding fit with the first inclined block 6. The guide rails 15 prevent the first swash block 6 from moving back and forth on the base 1 as shown in fig. 1.

The first inclined block 6 is fixedly connected with two baffle plates 16, the two baffle plates 16 are distributed on the inclined plane of the first inclined block 6 in parallel, and the clamp seat 8 is just embedded into a cavity formed by the two baffle plates 16. The two stops 16 prevent the gripper seat 8 from moving back and forth on the first ramp 6 as shown in figure 1.

The working principle is as follows: the first rotating handle 4 is rotated to drive the screw rod 3 to rotate, so that the pushing block 5 pushes the first inclined block 6 to move horizontally on the guide rail 15 towards the second inclined block 7. During the movement of the first swash block 6 towards the second swash block 7, the clamp seat 8 is gradually "lifted". The length scale mark 602 is drawn on the first sloping block 6, the clamp seat 8 is fixedly connected with the round rod 17, the round rod 17 is fixedly connected with the arrow head 18, and the tip of the arrow head 18 points to the length scale mark 602 vertically. The height of the position of the clamp base 8 is directly and prominently indicated by the arrow head 18 pointing to the length scale mark 602.

When using base 1, pass through the bolt fastening with base 1 horizontally on the lathe platform of polishing, the lathe of polishing chooses conventional horizontal grinding wheel lathe for use, for this technical field lathe commonly used, the grinding apparatus passes through the hydraulic stem on the lathe and stretches out and draws back and realize descending. Setting: when the fixture base 8 abuts against the guide rail 15, that is, the fixture base 8 is located at the lowest point, the height of the bottom surface of the cylindrical mirror 19 and the height of the upper surface of the fixture base 8 are both 0, and the scale on the length scale mark 602 pointed by the tip of the arrow mark 18 and pointing vertically is also 0. Note that the thickness of the cylindrical mirror 19 after blank cutting is L1, and the height of the cylindrical mirror 19 rising along with the jig base 8 is L2. The maximum travel of the grinder descending is H, and when the grinder descends to the lowest point, the lower surface of the grinder abuts against the upper surface of the clamp seat 8 located at the lowest point.

Before grinding, the lower surface of the cylindrical mirror 19 is at the lowest point, and the first rotating handle 4 is rotated to raise the lower surface of the cylindrical mirror 19 to the height of L2. And starting a hydraulic control system to control the grinding tool to descend, when the lower surface of the grinding tool descends to the height of L1+ L2, enabling the lower surface of the grinding tool to be in contact with the upper surface of the cylindrical mirror 19, turning on a rotary switch of the grinding tool, starting grinding the cylindrical mirror 19 by the grinding tool, when the grinding tool descends to the height of H-L1, turning off the rotary switch of the grinding tool, stopping grinding, wherein the thickness of the roughly-ground cylindrical mirror 19 is L1-L2, and L2 is the thickness of the cylindrical mirror 19 to be ground.

Because the inclined plane of the second inclined block 7 and the inclined plane of the first inclined block 6 are both 45-degree inclined planes, and the abutting surfaces of the clamp seat 8 and the second inclined block 7 and the abutting surfaces of the clamp seat 8 and the first inclined block 6 are both 45-degree inclined planes, according to the trigonometric function knowledge, the horizontal movement distance of the first inclined block 6 is the ascending movement distance of the clamp seat 8, the minimum scale of the length scale mark 602 is drawn to be 1 mm, and the thickness accuracy of the cylindrical mirror 19 after coarse grinding can reach the millimeter level, thereby meeting the requirement of coarse grinding.

For the rough grinding stage, L1> > L2, if the height of the clamp seat 8 is not adjusted by the first inclined block 6, when the thickness of the cylindrical mirror 19 to be ground is L2, the grinding tool needs to descend to reach H-L1+ L2 to meet the requirement of grinding the cylindrical mirror 19, and the stroke error of the descent of the grinding tool H-L1 is far smaller than that of the descent of the grinding tool H-L1+ L2, so the rough grinding result can be more accurate and reliable.
