Description

Technical Field

[0001] The utility model relates to a high-speed shaft external cylindrical grinding clamping tool, belonging to the technical field of high-speed shaft external cylindrical grinding. Background Art

[0002] High-speed shaft is a kind of bearing. Generally, high-speed shaft refers to the bearing with a speed of 60 meters per second. The high-speed shaft is not determined by the rotational speed, but by the linear speed. Small shafts or bearings that rotate tens of thousands of times are not considered high-speed bearings, while extra-large shafts or bearings that rotate hundreds of times are considered high-speed shafts.

[0003] There are still some problems in the use of an existing high-speed shaft external cylindrical grinding clamping tooling. For example, when clamping the high-speed shaft, due to the different diameters of high-speed shafts of different specifications, when the high-speed shaft is clamped, sometimes shaking occurs inside the clamping device. In addition, due to the different lengths of the high-speed shaft, the distance of the clamping device needs to be adjusted. The existing adjustment method is basically through manual adjustment, resulting in relatively low adjustment efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a high-speed shaft external cylindrical grinding clamping tool. The utility model has a simple structure and is easy to use. It can clamp high-speed shafts of different diameters and can quickly clamp and position high-speed shafts of different lengths to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, the electric control box is electrically connected to the grinder, and the No. 1 connecting plate and the No. 2 connecting plate have the same area.

[0009] Furthermore, the return spring is symmetrically distributed between the positioning cover and the upper top wall of the clamping ring, and the positioning cover is located inside the clamping ring.

[0010] Furthermore, the screw is rotatably connected to the inside of the threaded tube through a rotating cover, and the bottom of the screw is located at the top of the positioning cover.

[0011] Furthermore, the motor is electrically connected to the electric control box, and the screw rod is rotatably connected to the inside of the movable slot.

[0012] Furthermore, the moving rod is slidably connected to the inside of the moving groove, and the top of the moving rod is fixedly connected to the bottom of the second connecting plate.

[0013] The beneficial effects of the utility model are:

[0014] (I) The utility model is provided with a base, and a first connecting plate and a second connecting plate are provided on the top of the base. When the workpiece body needs to be clamped, the two sides of the workpiece body are first placed inside the clamping ring. At this time, the screw is driven to rotate inside the threaded tube by the rotating cover, so that the screw moves downward inside the threaded tube. The positioning cover inside the clamping ring is squeezed by the movement of the screw, so that the positioning cover moves downward. When the positioning cover moves downward, it can move to the top of the workpiece body, so that the positioning cover can position the two ends of the workpiece body to prevent it from shaking during processing.

[0015] (ii) The utility model is provided with a base. When it is necessary to clamp workpieces of different lengths, the motor on the outside of the base is started through the electric control box. At this time, the motor drives the screw rod to rotate inside the base, and the rotation of the screw rod drives the rotating circle to rotate. Since a moving rod is fixedly connected to the top of the rotating circle, and the top of the moving rod is fixedly connected to the bottom of the second connecting plate, the moving rod has a limiting effect on the rotating circle. When the screw rod rotates, it can drive the rotating circle to move on the outside of the screw rod, so that the moving rod drives the second connecting plate to move on the top of the base, thereby achieving the effect of quickly clamping workpieces of different lengths.

[0025] Specifically, Figure 1As shown, the electric control box 3 is electrically connected to the grinder 4, the area of ​​the No. 1 connecting plate 5 and the No. 2 connecting plate 6 are the same, the reset spring 9 is symmetrically distributed between the positioning cover 10 and the upper top wall of the clamping ring 7, and the positioning cover 10 is located inside the clamping ring 7, the screw 12 is rotatably connected to the inside of the threaded tube 11 through the rotating cover 13, and the bottom of the screw 12 is located on the top of the positioning cover 10.

[0026] In the present embodiment: a base 1 is provided, and a first connecting plate 5 and a second connecting plate 6 are provided on the top of the base 1. When the workpiece body 8 needs to be clamped, the two sides of the workpiece body 8 are first placed inside the clamping ring 7. At this time, the screw 12 is driven to rotate inside the threaded tube 11 by the rotating cover 13, so that the screw 12 moves downward inside the threaded tube 11. The movement of the screw 12 squeezes the positioning cover 10 inside the clamping ring 7, so that the positioning cover 10 moves downward. When the positioning cover 10 moves downward, it can be moved to the top of the workpiece body 8, so that the positioning cover 10 positions the two ends of the workpiece body 8 to prevent it from shaking during processing.

[0027] Example 2 Please refer to Figure 1 , Figure 2 and Figure 4 The difference between this embodiment and embodiment 1 is that a movable groove 14 is opened inside the base 1, a motor 15 is fixedly connected to the outside of the base 1, a screw rod 16 is fixedly connected to the output end of the motor 15, a rotating ring 17 is threadedly connected to the outside of the screw rod 16, and a movable rod 18 is fixedly connected to the top of the rotating ring 17.

[0029] In this embodiment: by setting up a base 1, when it is necessary to clamp the workpiece bodies 8 of different lengths, the motor 15 on the outside of the base 1 is started through the electric control box 3, and then the motor 15 will drive the screw rod 16 to rotate inside the base 1, and the rotation of the screw rod 16 will drive the rotating circle 17 to rotate. Since a moving rod 18 is fixedly connected to the top of the rotating circle 17, and the top of the moving rod 18 is fixedly connected to the bottom of the second connecting plate 6, the moving rod 18 will limit the rotating circle 17. When the screw rod 16 rotates, it can drive the rotating circle 17 to move on the outside of the screw rod 16, so that the moving rod 18 drives the second connecting plate 6 to move on the top of the base 1, thereby achieving the effect of quickly clamping the workpiece bodies 8 of different lengths.
