Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes an automatic centering and clamping mechanism for grinding the outer diameter of a ring gauge. It includes a support plate 1 with a set of evenly spaced movable openings 2. Each movable opening 2 has a sliding seat 3 slidably connected to it. The top of each sliding seat 3 is detachably connected to a clamping block 4 via an internal hex bolt. A bracket 5 is fixedly connected to the lower end face of the support plate 1. A first screw 6 is rotatably connected to the bracket 5. The top of the first screw 6 is rotatably connected to the support plate 1 via a bearing 7. A movable seat 8 is threaded onto the first screw 6. A set of connecting rods 9 are evenly rotatably connected to the movable seat 8. The top of each component is rotatably connected to the slide block 3. The lower side of the bracket 5 is provided with a rotating mechanism 10 for driving the first screw 6 to rotate, and the lower side of the bearing plate 1 is provided with a height adjustment mechanism 11 for adjusting its height. The rotation of the first screw 6 can cause the moving seat 8 to move up or down. The movement of the moving seat 8 will drive the connecting rod 9 to move. The movement of the connecting rod 9 will drive the slide block 3 and the clamping block 4 to move, thereby facilitating the clamping and release of the ring gauge, ensuring the accuracy and stability during the clamping process, facilitating the clamping of ring gauges of different sizes, and having a wider range of applications.

[0031] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the rotating mechanism 10 further includes a connecting shaft 1001 fixed to the bottom end of the first screw 6. The bottom end of the connecting shaft 1001 is fixedly connected to a first worm gear 1002. The lower end face of the bracket 5 is symmetrically and fixedly connected to two connecting blocks 1003. A first worm 1004 that meshes with the first worm gear 1002 is rotatably connected between the two connecting blocks 1003. One end of the first worm 1004 is fixedly connected to a first handwheel 1005. By rotating the first handwheel 1005, the first worm 1004 is driven to rotate. The rotation of the first worm 1004 will drive the first worm gear 1002 and the connecting shaft 1001 to rotate, thereby driving the first screw 6 to rotate. It also has a self-locking function.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, in a preferred embodiment, based on the above method, the height adjustment mechanism 11 further includes a base frame 1101 disposed on the lower side of the support plate 1. A guide rod 1102 is fixedly connected to one side of the base frame 1101, and a sliding plate 1103 is slidably connected to the guide rod 1102. The inner end of the sliding plate 1103 is fixedly connected to the bracket 5. A second screw 1104 is rotatably connected to the other side of the base frame 1101. A height adjustment plate 1105 is threadedly connected to the second screw 1104, and the inner end of the height adjustment plate 1105 is fixedly connected to the bracket 5. The bottom end of the second screw 1104 is fixedly connected to a second worm gear 110 through a connecting shaft 1106. 7. A connecting frame 1108 is fixedly connected to the side of the base frame 1101 near the second screw 1104. A second worm 1109, which meshes with the second worm gear 1107, is rotatably connected inside the connecting frame 1108. A second handwheel 1110 is fixedly connected to one end of the second worm 1109. By rotating the second handwheel 1110, the second worm 1109 is rotated. The rotation of the second worm 1109 drives the second worm gear 1107 and the second screw 1104 to rotate, thereby causing the height adjustment plate 1105 to move the bracket 5 and the bearing plate 1 up and down. This allows for easy adjustment of the height of the clamping mechanism according to the processing requirements of the workpiece, improving the flexibility of processing.

[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, two base plates 1111 are symmetrically and fixedly connected to the front and rear side walls of the base frame 1101, and each base plate 1111 is provided with mounting holes; the base plates 1111 can increase the support area at the bottom of the base frame 1101, improve the stability of the clamping mechanism, and the mounting holes facilitate the fixing of the base plates 1111.

[0034] like Figure 1 As shown, in a preferred embodiment, based on the above method, a rubber sleeve 12 is further fixedly connected to the clamping block 4, and the outer surface of the rubber sleeve 12 is provided with anti-slip texture; the rubber sleeve 12 not only increases the friction between the clamping block 4 and the workpiece, preventing the workpiece from sliding during processing, but its soft material can also protect the surface of the workpiece from damage.

[0035] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the number of movable opening 2, slide 3, clamping block 4 and connecting rod 9 are three respectively; this facilitates the self-centering and stable clamping and fixing of the ring gauge, and ensures the accuracy of clamping the ring gauge.

[0036] Specifically, in use, the automatic centering and clamping mechanism for the external cylindrical grinding of this ring gauge works as follows: First, the ring gauge to be clamped is placed on the support plate 1. Then, the first handwheel 1005 is rotated to drive the first worm gear 1004 to rotate. The rotation of the first worm gear 1004 drives the first worm wheel 1002 and the connecting shaft 1001 to rotate, which in turn drives the first screw 6 to rotate. The rotation of the first screw 6 causes the moving seat 8 to move upward. The movement of the moving seat 8 drives the connecting rod 9 and the slide 3 to move, thereby causing the clamping block 4 to move outward synchronously, thus clamping and fixing the ring gauge from the inside. When the height needs to be adjusted, the second handwheel 1110 is rotated to drive the second worm gear 1109 to rotate. The rotation of the second worm gear 1109 drives the second worm wheel 1107 and the second screw 1104 to rotate, which in turn causes the height adjustment plate 1105 to drive the bracket 5 and the support plate 1 to move up and down, so as to flexibly adjust the height according to the actual processing requirements.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
