Description

Technical Field

[0001] The utility model relates to the technical field of lens polishing and fixing, in particular to a replaceable ball seat for lens polishing and fixing. Background Art

[0002] During the lens production process, it needs to go through a fine grinding and polishing process, which is usually accomplished using a high-speed polishing machine. When using a high-speed polishing machine for polishing, the polishing fixture is designed and manufactured according to the optical lens product drawings that need to be produced. The part that fixes the optical lens is called the ball seat.

[0003] For example, the utility model with application number 202021111098.5 discloses a ball seat for polishing and fixing lenses with a curvature radius of 229.0. The utility model has a lens fixing chamber with a curvature radius of 229.0 mm recessed inward on the bottom surface of the ball seat body, so that the optical lens with a curvature radius of 229.0 mm can be accurately fitted and fixed, so that the optical lens with a curvature radius of 229.0 mm fixed on the ball seat body can be accurately polished by driving the polishing mold by the polishing machine at a uniform speed, ensuring that the optical lens with a curvature radius of 229.0 mm can be accurately polished, filling the gap of a special ball seat when polishing optical lenses with a curvature radius of 229.0 mm, which is conducive to improving the yield rate.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] When the existing lens polishing and fixing ball seat is used to fix the lens, two sets of different ball seats are needed according to the difference between the convex surface and the concave surface, which cannot achieve the purpose of universality. At the same time, due to the limitation of the firmness of the connection between the ball seat and the rotator, the ball seat is easy to fall off.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a replaceable lens polishing and fixing ball seat is proposed. Utility Model Content

[0007] The utility model aims to provide a replaceable ball seat for fixing lens polishing, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a replaceable lens polishing and fixing ball seat, comprising a rotator, a rotating shaft is provided at the power output end of the rotator, a mounting block is fixedly connected to the top of the rotating shaft, a connecting block is provided above the mounting block, a connecting head is fixedly connected to the top center of the mounting block, a mounting head is installed on the top of the connecting block, and a ball seat body is fixedly connected to the top of the mounting head;

[0011] Furthermore, a spherical groove is provided inside the center of the bottom of the ball seat body, the connecting head penetrates the center of the connecting block, and the mounting head and the ball seat body form an integrated structure. The ball seat body can be driven to rotate through the function of the mounting block and the connecting block, and the purpose of polishing can be achieved by combining with the polishing equipment through high-speed rotation.

[0012] Furthermore, the combination mechanism includes a combination frame, which is installed at both ends of the installation block. There are four groups of the combination frames, which are installed on both sides of the installation block and the connecting block near the center. The centers of both ends of the bottom of the connecting block are rotatably connected with fixing pins. Through the action of the combination frame, the installation block and the connecting block can be clamped and fixed from the outside at both ends.

[0013] Furthermore, one end of the bottom of the fixing pin is fixedly connected to a limiting pin, limiting grooves are provided inside the two ends of the bottom of the connecting block, and a positioning buckle is fixedly connected to the top of the fixing pin. The positioning buckle can be used to fix the assembly frame from both sides to avoid detachment.

[0014] Furthermore, the fixing mechanism includes an adjustment rail, which is fixedly installed at the center of the four faces of the ball seat body, and an adjustment column is slidably connected to the upper part of the adjustment rail. The height of the fixing rod can be adjusted by moving the adjustment column in the adjustment rail.

[0015] Furthermore, an adjustment slot is provided inside the lower part of the top of the adjustment column, a fixing rod is slidably connected inside the adjustment slot, and a pressing block is installed at the bottom of the fixing rod near the center of the ball seat body.

[0016] Furthermore, the adjusting rail is internally rotatably connected with a lifting screw rod, and the bottom of the lifting screw rod is fixedly connected with a rotating buckle. The position of the adjusting column can be moved by rotating the lifting screw rod, and the height of the fixing rod and the pressing block can be adjusted by the adjusting column.

[0017] The utility model provides a replaceable ball seat for fixing lens polishing, which has the following beneficial effects:

[0018] Firstly, the utility model sets a fixing mechanism, and after the mounting block and the connecting block are correspondingly combined, the connecting head can be inserted into the interior of the mounting head, thereby completing the combined connection between the rotator and the ball seat body. At the same time, through the action of the combination frame, the fixing pin and the positioning buckle, the combination frame, the mounting block and the connecting block are reinforced to avoid separation, thereby avoiding separation in the case of high-speed rotation.

[0019] Secondly, the utility model sets a fixing mechanism to fit the convex part of the spherical surface of the lens with the inner wall of the spherical groove, and adjusts the position of the fixing rod according to the diameter of the lens, so that the pressing block can fit tightly with the centers of the four sides of the lens, thereby completing the connection and fixation between the lens and the ball seat body. When the convex part of the spherical surface is polished upward, the lens is pressed and fixed from the top of the centers of the four sides of the lens at the same time. Such a setting can enhance the applicability of the ball seat body. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the attached Figures 1 to 4 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a fixing fixture for steel pipe perforation processing through improvement. Figure 1-Figure 4 As shown, it includes a rotator 1, a rotating shaft is provided at the power output end of the rotator 1, a mounting block 2 is fixedly connected to the top of the rotating shaft, a connecting block 3 is provided above the mounting block 2, a connecting head 4 is fixedly connected to the top center of the mounting block 2, a mounting head 5 is installed on the top of the connecting block 3, and a ball seat body 6 is fixedly connected to the top of the mounting head 5; a combination mechanism for combining the connecting block 3 and the mounting block 2 is provided on the outside of the connecting block 3; a fixing mechanism for fixing the lens is provided at the center of the four faces of the ball seat body 6. A spherical groove 7 is provided inside the bottom center of the ball seat body 6, the connecting head 4 runs through the inside of the center of the connecting block 3, and the mounting head 5 and the ball seat body 6 form an integrated structure.

[0027] In this embodiment, a spherical groove 7 is opened inside the bottom center of the ball seat body 6, so when the concave surface of the lens is polished, the concave surface faces upward, and the convex surface is tightly fitted with the inner wall of the spherical groove 7, and when the convex surface of the lens is polished, the convex surface faces upward. Since the maximum diameter of the spherical groove 7 is smaller than the diameter of the lens, the concave surface of the lens covers the spherical groove 7, and then cooperates with the fixing rod 15 and the pressure block 16 to complete the fixation of the lens, thereby increasing the applicability of the ball seat body 6.

[0028] In the first implementation scheme, due to the premise of high-speed rotation, it is easy to disengage, and the specific operation is as follows:

In the case of double fixing, it can avoid the situation of separation during high-speed rotation;

[0031] In the previous embodiment, since the lens has a concave surface and a convex surface, a ball seat body 6 with a different structure needs to be used. The specific operation is as follows:

[0032] like Figure 3 and Figure 4 As shown, the fixing mechanism includes an adjustment rail 13, which is fixedly installed at the center of the four faces of the ball seat body 6, and an adjustment column 14 is slidably connected to the upper part of the adjustment rail 13. An adjustment groove is provided inside the adjustment column 14, which is slightly below the top, and a fixing rod 15 is slidably connected inside the adjustment groove.
