Description

Technical Field

[0001] This utility model relates to the field of grinding machine rotary table technology, and in particular to a rotary table for a frustum surface grinder. Background Technology

[0002] Grinding machines are common equipment in machining centers, including a worktable that fixes the workpiece and cutting tools that grind the workpiece. Vertical grinding machines usually use a rotary table with an electromagnetic chuck to fix the workpiece. The rotary table drives the workpiece to rotate, and the cutting tools perform the corresponding machining operations on the workpiece. Currently, when installing workpieces of different sizes, it is necessary to change the rotary table to the same size, and the process of changing the rotary table is slow. Therefore, those skilled in the art provide a rotary table for a frustum surface grinder to solve the problems mentioned in the background art. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0024] Reference Figures 1-4 A rotary table for a frustum surface grinder includes a mounting plate 1. A positioning ring 2 is fixedly mounted on the surface of the mounting plate 1. Guide grooves are provided on both sides of the surface of the positioning ring 2. A mounting block 3 is snapped onto the surface of the positioning ring 2. A mounting groove is provided inside the mounting block 3. Limiting blocks 4 are fixedly mounted at the four corners inside the mounting groove. A placement block 5 overlaps on the surface of the limiting block 4. Limiting grooves are provided at the four corners inside the placement block 5. A positioning component 6 is provided inside the limiting groove. Several insertion grooves are provided at the bottom of the placement block 5. Electromagnetic plates 7 are provided inside the insertion grooves. Support rods 8 are fixedly mounted at the four corners of the bottom of the electromagnetic plate 7. The size of the support rods 8 is adapted to the size of the insertion grooves. Rolling grooves are provided at the four corners of the surface of the mounting plate 1. Rollers 9 are provided inside the rolling grooves. A power component 10 is provided on the surface of the mounting block 3. Mounting components 11 are fixedly mounted on both sides of the mounting plate 1.

[0025] The power assembly 10 includes a meshing ring 101 fixedly mounted on the surface of the mounting block 3. A rotating plate 102 is meshed on one side of the surface of the meshing ring 101, and a servo motor 103 is provided at the bottom of the rotating plate 102.

[0026] During use, the operator installs the servo motor 103 on one side of the mounting plate 1. Then, the output end of the servo motor 103 will drive the rotating plate 102 to rotate. When the rotating plate 102 rotates, it will drive the meshing ring 101 to rotate. When the meshing ring 101 rotates, it will drive the workpiece inside the mounting block 3 to rotate.

[0027] In this utility model, the positioning component 6 includes a telescopic rod 61 fixedly installed inside the limiting groove. A spring 62 is sleeved on the surface of the telescopic rod 61. A positioning plate 63 is fixedly installed at one end of the telescopic rod 61. A conical block 64 is fixedly installed on the surface of the positioning plate 63. A positioning block is fixedly installed at one end of the telescopic rod 61. The diameter of the positioning block is larger than the diameter of the spring 62. One end of the spring 62 is fixedly installed on the back of the positioning block. The size of the limiting groove is adapted to the size of the positioning plate 63. The positioning plate 63 can move inside the limiting groove.

[0028] In particular, when positioning the workpiece, the operator places the workpiece inside the limiting groove, and then the workpiece will press the positioning plate 63 through the conical block 64. After the positioning plate 63 is pressed, the telescopic rod 61 and spring 62 on the back of the positioning plate 63 will be compressed accordingly. After the spring 62 on the telescopic rod 61 is compressed, the spring 62 will reset accordingly. The telescopic rod 61 will drive the positioning plate 63 to move synchronously to the center, and the conical block 64 on the positioning plate 63 will install and position the workpiece.

[0029] In this utility model, a limiting groove is provided at each of the four corners of the surface of the mounting block 3. An air flow channel is formed between the limiting groove and the guide groove. The size of the mounting groove is adapted to the size of the placement block 5. The limiting block 4 inside the mounting groove can position the placement block 5. An arc-shaped groove is provided on both sides of the surface of the mounting block 3. An arc-shaped plate is engaged inside the arc-shaped groove.

[0030] In particular, the bottom of the mounting block 3 is provided with a limiting groove. The air flow channel between the limiting groove and the guide groove will dissipate the heat generated by the rotation between the positioning ring 2 and the mounting block 3, which improves the service life of the rotary table, and the electromagnetic plate 7 can position the workpiece.

[0031] In this utility model, the mounting component 11 includes a limiting plate 111 fixedly mounted on both sides of the mounting plate 1. A threaded groove is provided in the middle of the surface of the limiting plate 111. A threaded rod 112 is threadedly connected inside the threaded groove. One end of the threaded rod 112 is rotatably connected to a clamping plate 113.

[0032] In particular, after the personnel place the mounting plate 1 in a suitable position, the personnel rotate the threaded rod 112 through the mounting plate 111. When the threaded rod 112 rotates, it will drive the clamping plate 113 to move towards the center. When the clamping plate 113 moves, it will install the mounting plate 1, which improves the stability of the mounting block 3 on the mounting plate 1 when processing the workpiece.

[0033] Working principle: When it is necessary to position the workpiece, the operator places the workpiece inside the limiting groove. The workpiece will then press the positioning plate 63 through the conical block 64. After the positioning plate 63 is pressed, the telescopic rod 61 and spring 62 on the back of the positioning plate 63 will be compressed. After the spring 62 on the telescopic rod 61 is compressed, the spring 62 will return to its original position. The telescopic rod 61 will drive the positioning plate 63 to move synchronously towards the center. The conical block 64 on the positioning plate 63 will install and position the workpiece. Then, the bottom of the mounting block 3 is provided with a limiting groove. The air flow channel between the limiting groove and the guide groove will dissipate the heat generated by the rotation between the positioning ring 2 and the mounting block 3.

[0034] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
