Description

Technical Field

[0001] This application relates to the field of high-precision grinding technology, and in particular to rotary platforms for high-precision grinding machines. Background Technology

[0002] The development of silent precision grinding machines is a product of the high-end manufacturing industry, increasingly stringent environmental regulations, and upgraded customer demands, reflecting the industry's emphasis on sustainable development and worker health protection.

The adjustment platform attracts the workpiece and is driven to rotate by the motor, thus replacing the original X and Y axis adjustments. Only the Z-axis grinding wheel's up-and-down movement remains adjustable. When grinding small workpieces, it is unnecessary to repeatedly move the X and Y axis guideways. In use, simply open the rotary platform of the high-precision grinding machine and directly adjust the grinding wheel height, thereby saving time during surface grinding.

[0004] In the existing technology, the workpiece cannot be fixed on the platform, nor can it be flipped, which causes inconvenience to the grinding of the workpiece. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to fix the workpiece on the platform and the inability to rotate the workpiece, which causes inconvenience for workpiece grinding, and to propose a rotary platform for high-precision grinding machines.

[0006] The high-precision grinding machine rotary platform provided in this application adopts the following technical solution:

[0007] A rotary platform for a high-precision grinding machine includes: a base, a motor mounted on the bottom inner side of the base, a worktable rotatably connected to the top of the base, and the output shaft of the motor fixedly connected to the worktable; and further includes:

[0008] The housing is fixedly mounted on top of the base;

[0009] All three power mechanisms are fixedly installed inside the housing;

[0010] The clamping mechanism, located inside the worktable, is used to clamp and fix the workpiece.

[0011] The height adjustment mechanism, located inside the worktable, is used to adjust the height of the workpiece.

[0012] The flipping mechanism, located inside the worktable and on the clamping mechanism, is used to flip the workpiece.

[0013] The clamping mechanism includes a rotating platform slidably disposed inside the worktable. The top of the rotating platform has two sliding grooves, and a slider is slidably connected in each of the two sliding grooves. A connecting block is fixedly connected to the top of each of the two sliders, and an adjusting block is fixedly connected to the top of each of the two connecting blocks.

[0014] Both of the first adjustment blocks and the two connecting blocks are slidably connected to the worktable. The two first adjustment blocks are fixedly connected to the side of each other. The two second adjustment blocks are rotatably connected to the side of each other. The two fixed blocks are slidably connected to the side of each other.

[0015] The flipping mechanism includes a rotating shaft four rotatably disposed inside the worktable. The two ends of the rotating shaft four are rotatably connected to two connecting blocks respectively. Both ends of the rotating shaft four are fixedly connected to a worm gear two.

[0016] Furthermore, the height adjustment mechanism includes a rotating shaft two rotatably disposed inside the worktable, with both ends of the rotating shaft two rotatably connected to two connecting blocks respectively, and both ends of the rotating shaft two fixedly connected to a bevel gear three, which meshes with a bevel gear four, and the rotating shaft three is fixedly connected to the bevel gear four, and the rotating shaft three is rotatably connected to the connecting blocks.

[0021] 1. This solution uses a power mechanism that works in conjunction with the clamping mechanism to drive the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the rotating shaft to rotate, which in turn drives the rotating table to rotate.

Through linkage, the two rotating shafts drive the two screws to rotate, which in turn drives the two moving plates to move upward. At the same time, it drives the two adjusting blocks, the two fixed blocks, the four clamping plates and the workpiece to move upward, thus adjusting the height.

This solution uses a power mechanism adapted to the flipping mechanism to drive the rotating column two to rotate, and through linkage, the two bevel gears seven drive the two rotating shafts six to rotate, thereby driving the two fixed blocks, four clamping plates and the workpiece to flip.

[0024] This invention can clamp and fix the workpiece, and can automatically flip the workpiece, thereby improving the grinding efficiency of the workpiece. Attached Figure Description

A slot is provided at one end of the rotating shaft 39.

[0046] The implementation principle of the rotary platform for the high-precision grinding machine in this application embodiment is as follows: In use, the workpiece is first placed between four clamping plates 11. Then, through a power mechanism cooperating with the clamping mechanism, the push rod motor 37 is started. The output end of the push rod motor 37 drives the second motor 38 and the rotating shaft 39 to move, so that the slot of the rotating shaft 39 matches the rotating column and locking block at the front end of the worm gear 12. Then, the second motor 38 is started, and the output shaft of the second motor 38 drives the worm gear 12 to rotate. The worm gear 12 drives the worm wheel 13 to rotate. 13 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the rotating table 5 to rotate, and the rotating table 5 can drive the two sliders 6 to move closer to each other through the slide groove 15.

Then, the two motors 1 are started, and the output shafts of the two motors 1 drive the two reciprocating screws 35 to rotate at the same time, so that the workpiece can be clamped and fixed by the four clamping plates 11.

[0047] By using a power mechanism adapted to the height adjustment mechanism, the push rod motor 37 is started. The output end of the push rod motor 37 drives the second motor 38 and the rotating shaft 39 to move, so that the slot of the rotating shaft 39 matches the rotating column 16 and the protrusion on the outer surface of the rotating column 16. Then, the second motor 38 is started. The output shaft of the second motor 38 drives the rotating column 16 to rotate. The rotating column 16 drives the bevel gear 17 to rotate. The bevel gear 17 drives the bevel gear 18 to rotate. The bevel gear 18 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the two bevel gears 20 to rotate. The two bevel gears 20 drive the two bevel gears 21 to rotate. The two bevel gears 21 drive the two rotating shafts 22 to rotate. The two rotating shafts 22 drive the two screws 23 to rotate.

At the same time, it drives the two adjusting blocks 9, the two fixed blocks 10, the four clamping plates 11, and the internal parts and workpieces of the two adjusting blocks 9 and the two fixed blocks 10 to move upward, thus adjusting the height.

[0048] When flipping is required, the workpiece is first moved to its highest position via the height adjustment mechanism. Then, the push rod motor 37 is activated via a power mechanism adapted to the flipping mechanism. The output end of the push rod motor 37 drives the second motor 38 and the rotating shaft 39 to move, so that the groove of the rotating shaft 39 matches the second rotating column 25 and the protrusion on the outer surface of the second rotating column 25. Then, the second motor 38 is activated, and the output shaft of the second motor 38 drives the second rotating column 25 to rotate. The second rotating column 25 drives the fifth bevel gear 26 to rotate, and the fifth bevel gear 26 carries... The rotating bevel gear 827 drives the rotating shaft 428 to rotate, which in turn drives the two worm gears 29 to rotate. The two worm gears 29 then drive the two worm wheels 230 to rotate, which in turn drives the two rotating shafts 531 to rotate. The two rotating shafts 531 then drive the two bevel gears 632 to rotate, which in turn drive the two bevel gears 733 to rotate, which in turn drive the two rotating shafts 634 to rotate. This process causes the two fixed blocks 10, the four clamping plates 11, and the workpiece to rotate.
