Problems solved by technology

The arbitrary indexing of the vernier indexing plate studied is achieved by combining the indexing plate and the indexing head. In fact, it is equivalent to a vernier-type protractor, and the indexing is done by reading the angle, which is different from the traditional indexing. Huge difference

Embodiment Construction

[0022] The present invention will be described in more detail below with examples in conjunction with the accompanying drawings.

[0023] The vernier type indexing plate assembly of the present invention consists of a positioning pad 1, a fixed top cover 2, a swing rod 3, a cursor 4, a hole plate pin 5, a pin spring 6, a pin handle 7, a fixing screw 8, a bolt 9, and a positioning bolt 10 , spacer spring 11 and rod frame 12, this component is installed on the universal indexing head for use, and has two working states: after the swing rod 3 is fixed, it is the same as the handle of the ordinary indexing head; after the swing rod 3 is fixed, according to the principle of the vernier caliper Use the cursor 4, the pendulum 3 and the orifice plate together. Figure 6 The hole plate in the table is the index plate provided by the "Global" brand F11125 indexing head, and the number of holes in each circle is as follows:

[0024] First side: 24, 25, 28, 30, 34, 37, 38, 39, 41, 42, 43...

Abstract

The invention provides a vernier index plate unit comprising a positioning pad, a fixed top cover, a swing rod, a vernier scale, an orifice disc pin, a pin spring, a pin handle, a fixing screw, a bolt, a positioning bolt, a pad spring, and a rod carrier. The vernier index plate unit is available in two operating modes when applied to a universal index head. When the vernier scale is not mounted, the positioning pad fastens the swing rod to a set position by rotating a positioning pin, and the vernier index plate unit is used in the same as a common index rocker. When the vernier scale is mounted, the vernier scale is mounted on the rod carrier first, the swing rod is loosened and can rotate freely, and meanwhile, an index disc and the vernier scale are used together for indexing according to the principle of vernier caliper, so that indexing capacity of the universal index head is greatly improved. The vernier index plate unit has the advantages of ingenious structure, simplicity in operation, stable performance, economy and the like; indexing capacity can be greatly improved without changing the universal index head.

Description

technical field [0001] The invention relates to an indexing device, in particular to a vernier type indexing plate assembly. Background technique [0002] When performing turning, milling, drilling, etc., some features uniformly distributed along the circumference need to be indexed to achieve processing, such as the processing of bolts and gears. The universal indexing head is the most commonly used indexing device, which has the advantages of large number of indexing, accurate indexing, stable performance and simple operation. One of the important components to achieve indexing is the indexing plate. Usually, the universal will be equipped with two indexing plates, and each indexing plate has holes for indexing on both sides. The indexing holes are processed intensively and require a large amount of processing. In addition, if one indexing plate cannot meet the indexing time of a batch of parts, it is necessary to disassemble and replace the indexing plate, or even buy a ...
