Embodiment Construction
[0027] See figure 1 , the high-precision rotary indexing plate of the present invention includes a base 1, an indexing plate 2, a rotary plate 3 and an indexing pin 4, and the indexing plate 2 is in the shape of a ring disc, see Image 6 with Figure 7 , the top surface of the indexing plate 2 is evenly distributed along the circumferential direction with a number of indexing grooves 10, the indexing plate 2 is provided with a ring-shaped step surface 11, and a number of positioning holes 12 are opened on the ring-shaped step surface 11, and positioning pins 9 , Bolts 8 fix the indexing plate 2 on the base 1 through any two positioning holes 12 respectively. Usually, in order to ensure the reliable installation and stability of the indexing plate 2 under certain circumstances, the circular ring located on the indexing plate 2 should be selected. Two positioning holes 12 on the same diameter of the step surface 11 are used to install positioning pins 9 and bolts 8 respectively...

The invention provides a high-precision rotating dividing disc. The high-precision rotating dividing disc can solve the problem that a conventional worm-gear-operated dividing device is complex in structure and large in dividing error, can be conveniently applicable to dividing operation of large parts, and improves the machining efficiency. The high-precision rotating dividing disc comprises a base, a dividing disc body, a rotating disc and dividing plug pins. Dividing grooves are formed in the dividing disc body, and the dividing plug pins are installed on the rotating disc. The dividing disc body is fixedly installed on the base, the rotating disc is installed on the base in a rotatable mode, and the dividing disc body and the rotating disc are arranged in a concentric mode, and are located and locked through the dividing plug pins. When the dividing disc body and the rotating disc are located and locked, the dividing plug pins are inserted into the dividing grooves of the dividing disc body. The rotating disc is supported on the base through a plane swing bearing.
Description
technical field [0001] The invention relates to the field of mechanical processing devices, in particular to an indexing device, specifically a high-precision rotary indexing plate. Background technique [0002] The traditional indexing device realizes the transmission of the worm gear through the rotation of the handle, and then drives the indexing plate to rotate, and at the same time realizes the indexing through the positioning of the positioning pin and the indexing plate. Its structure is complex, and there is a large cumulative error in the indexing achieved through the transmission chain; at the same time, the traditional indexing device is usually only suitable for the indexing operation of small and medium-sized parts due to the large friction in the transmission system. When the weight is heavy, the operating force is large and it is inconvenient to use. Contents of the invention [0003] In view of the above problems, the present invention provides a high-prec...
