Description

Technical Field

[0001] This utility model relates to the field of grinding tooling technology, specifically a grinding tooling turntable system for disc-type robots. Background Technology

[0002] In the field of automation, rotary tables are frequently used devices, generally used to transfer workpieces or to rotate and change the position of products, and have a wide range of applications. For automated rounding and grinding of disc-shaped parts after rotary machining, it is necessary to ensure both rotational accuracy and clamping accuracy. Traditionally, rounding of disc-shaped parts is mainly done manually, with the rotary table only ensuring rotational function and positioning accuracy relying on manual adjustments. In automated processes, part positioning calibration must be performed first, and coordinate calibration completed before subsequent automated machining operations can be achieved through offline programming software. Standard rotary tables used manually do not meet the requirements of automated processes. Utility Model Content

[0017] It should be noted that in this embodiment, the workpiece is placed outside the fixing claw 8, and the workpiece is supported and fixed by the outward sliding of the fixing claw 8. The height of the lifting platform 13 can be adjusted according to the height of the product, so that the height of the positioning block 11 is adapted to the workpiece 5. The lateral position of the positioning block 11 is adjusted according to the diameter of the workpiece 5, so that the positioning block 11 can contact the top, bottom, and sides of the workpiece 5, thereby achieving workpiece positioning and making it compatible with workpieces of different sizes. In the processing of disc-shaped parts, it assists in providing positioning that meets the requirements.

[0018] In one embodiment, a turntable cover 4 for protection is fixed to the top of the turntable frame 1.

[0019] It should be noted that in this embodiment, the turntable cover 4 can be used to block the debris generated during processing, preventing the debris from flying out of the processing position and facilitating the collection of the debris.

[0020] In one embodiment, the dust removal assembly includes a dust removal air inlet channel 2 opened at the top of the turntable frame 1 and a dust removal air outlet channel 3 opened at the bottom side of the turntable frame 1. The dust removal air inlet channel 2 and the dust removal air outlet channel 3 are connected by an air duct 20, and one end of the dust removal air outlet channel 3 is connected to a negative pressure device.

[0021] It should be noted that in this embodiment, the negative pressure device is a vacuum cleaner. The input end of the vacuum cleaner is connected to the dust removal air outlet channel 3. The vacuum cleaner creates a negative pressure at the position of the dust removal air inlet channel 2 through the dust removal air outlet channel 3 and the air duct 20. The dust and iron filings generated during grinding are collected and cleaned through the dust removal air inlet channel 2 and the air duct 20 to ensure a clean and hygienic working environment.

[0022] In one embodiment, the workpiece fixing part further includes a three-jaw pneumatic chuck 7 rotatably mounted on the top of the turntable frame 1, a fixing jaw 8 fixedly connected to the top of the jaw of the pneumatic chuck 7, a workpiece 5 with an annular structure sleeved on the outside of the fixing jaw 8, a protective cover 9 fixedly connected to the outside of the pneumatic chuck 7, and a drive unit for driving the fixing jaw 8 to rotate installed inside the turntable frame 1. The drive unit includes a servo motor 6 fixedly connected inside the turntable frame 1. The servo motor 6 is equipped with an encoder, and the output end of the servo motor 6 is connected to the pneumatic chuck 7 through a spur gear assembly.

[0023] It should be noted that in this embodiment, a hollow tube is rotatably connected to the middle of the turntable frame 1, and a rotary joint is installed at the bottom of the hollow tube. A pneumatic chuck 7 is fixed to the top of the hollow tube and is connected to the hollow tube through a hose. The opening and closing of the pneumatic chuck 7 is controlled by air pressure. The opening and closing of the pneumatic chuck 7 supports or clamps and fixes the disc shaft-type parts. A servo motor 6 is fixed inside the turntable frame 1. The output end of the servo motor 6 is fixed to a small gear through a reducer, and a large gear is fixed to the outside of the hollow tube. The small gear and the large gear mesh and are connected. The servo motor 6 drives the fixed claw 8 to rotate, which facilitates the grinding of the workpiece.

[0024] In one embodiment, the positioning assembly further includes a base 17 fixed to the top of the turntable frame 1, two lifting slide rods 18 fixed to the top of the base 17, a top limiting plate 14 fixedly connected to the top of the lifting slide rods 18, a lifting platform 13 slidably mounted on the outside of the lifting slide rods 18, and a tightening bolt 21 threadedly connected to the outside of the lifting platform 13 and corresponding to the position of the lifting slide rods 18 for fixing the height of the lifting platform 13.

[0025] It should be noted that, in this embodiment, when adjusting the height of the lifting platform 13, the tightening bolts 21 on both sides are screwed in, thereby causing the lifting platform 13 to slide up and down on the outside of the lifting slide rod 18. This, in turn, causes the lifting platform 13 to adjust the height of the positioning block 11, allowing it to align with the top and bottom of the workpiece. By rotating the tightening bolts 21, the ends of the tightening bolts 21 penetrate the lifting platform 13 and press and fix it to the positioning block 11, facilitating the positioning of the top or bottom of the workpiece.

[0026] In one embodiment, a fixed sliding sleeve 12 is fixedly connected to the top of the lifting platform 13, and a linear guide rail 19 is slidably connected inside the fixed sliding sleeve 12.

A limiting handle 16 for pressing and fixing the linear guide rail 19 is threadedly connected to the bottom of the lifting platform 13, and a proximity switch 10 is fixedly connected to one side of the lifting platform 13 at the position corresponding to the positioning block 11.

[0027] It should be noted that, in this embodiment, when adjusting the lateral position of the positioning block 11, the limiting handle 16 is rotated to separate its top from the bottom of the linear guide rail 19, and then the linear guide rail 19 is pulled by the handle 15. This causes the linear guide rail 19 to slide inside the fixed sliding sleeve 12, thereby adjusting the position of the positioning block 11. Combined with the detection of the proximity switch 10, the end position of the positioning block 11 can be detected. When the proximity switch 10 detects the end position of the positioning block 11, it sends a signal to the controller, which then controls the alarm or designated light to operate. The limiting handle 16 is then tightened, causing its top to press against the fixed linear guide rail 19. By fixing the linear guide rail 19, the position of the positioning block 11 can be fixed.
