Detailed Description

The utility model provides a precision circumference halving device graduated disk structure, it includes graduated disk 1, drive arrangement 2 and wedge locating pin 3, the graduated disk middle part is equipped with central locating hole 12, even wedge circumference constant head tank 8 of seting up a plurality of orientation graduated disk centers on the graduated disk outer fringe, the quantity of circumference constant head tank sets up according to the equant quantile of waiting to divide the part, the circumference constant head tank sets up to the wedge, make things convenient for the circumference locating pin to fix a position and slide-in and roll-off, a plurality of circumference driving groove 7 have been seted up to the graduated disk middle part is even.

The driven shaft 5 is arranged at the central positioning hole, a bearing is arranged between the driven shaft and the dividing plate to enable the dividing plate to rotate stably, a flat key 4 is arranged on the driven shaft to transmit driving force, and when the dividing plate rotates, a part to be divided (not shown) is driven to rotate together.

The number of the circumferential driving grooves is integral multiple of the number of the circumferential positioning grooves, and the number of the circumferential driving grooves can be set according to the operation space of the driving handle. Every an inner wall in circumference drive groove is slope 13, and when making things convenient for operating handle to rotate, the circumference actuating lever slides along the slope, makes the circumference actuating lever insert the circumference drive inslot, realizes that the handle rotation drives the graduated disk and rotates together to when the drive handle direction is rotatory, realize the drive handle and reset.

The middle part of the driving device is arranged on the driven shaft, so that the driving device can rotate around the driven shaft, the central positioning of the driving device is realized, and the inner end part of the driving device is provided with a circumferential driving rod 6.

Optimally, the driving device is a driving handle, the cost is low, and the operation is convenient.

Further, the inner end portion of the driving device is fixedly provided with a spring mounting seat 10, a spring is fixedly arranged in the spring mounting seat, the circumferential driving rod penetrates through the spring in the spring mounting seat, the lower end portion of the circumferential driving rod extends out of the spring mounting seat, a spring limiting step 11 is fixedly arranged in the middle of the circumferential driving rod, the circumferential driving rod can stretch in the vertical direction due to the arrangement of the spring, and the circumferential driving rod can slide along the slope of the circumferential driving groove and is always contacted with the dividing plate at the lower end portion.

The invention provides a precise circumferential equal-dividing device indexing disc structure. When indexing is performed, as shown in fig. 1, taking 8 equally as an example, and the number of the circumferential driving grooves is the same as that of the circumferential positioning grooves, the wedge-shaped positioning pin is initially clamped in one of the wedge-shaped circumferential positioning grooves of the indexing disk, the driving handle is located at the S position, and the lower end of the circumferential driving rod is located on the upper surface of the indexing disk between the two circumferential driving grooves. The driving handle is rotated clockwise to the M position, the driving handle rotates at the moment because the circumferential driving rod is not positioned in the circumferential driving groove, the dividing plate is not moved, and the circumferential driving rod gradually slides into the bottom in the circumferential driving groove along the slope of the circumferential driving groove in the process that the driving handle rotates to the M point. Continue clockwise rotation drive handle, make drive handle move to E point position, drive handle is rotatory in this period, can drive the graduated disk through the circumference actuating lever and rotate together to make circumference constant head tank extrusion circumference locating pin and break away from the circumference locating pin gradually, move to E point position until drive handle, the circumference locating pin just is located next circumference constant head tank this moment, the graduated disk is rotatory, can drive the part of waiting to divide equally through being driven the shaft and rotate together, thereby accomplish a graduation of waiting to divide equally the part. And then the driving handle is rotated reversely, so that the circumferential driving rod gradually slides out of the circumferential driving groove along the slope and returns to the S point for resetting. The next indexing rotation is performed and the above operation is repeated. The device is simple in structure, convenient and labor-saving to operate, extra electric energy and other power equipment are not needed, the manufacturing cost and the running cost are low, meanwhile, the structure positioning indexing precision is high, and the equal division effect of the parts to be equally divided is guaranteed.

When the operating space of twist grip is limited, can establish the quantity of circumference drive groove into the N times of circumference constant head tank quantity, the drive handle accomplishes N times rotation and the repetitive motion that resets, and a drive graduated disk accomplishes an graduation.

In conclusion, the dividing disc structure of the precise circumferential equal dividing device protected by the invention has the advantages of simple structure, low cost, convenience in operation and high equal dividing precision.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
