Description

an indexing device

technical field

The utility model relates to a mechanical processing device, in particular to an indexing device.

Background technique

In mechanical processing, there are often multi-station processing of the workpiece, such as the marking of the scale, the processing of gears and racks, the processing of splines, and the processing of other equally divided holes or equally divided grooves. After this kind of workpiece is clamped once, it needs to be indexed in the process of processing, that is, after finishing one surface processing, the workpiece and the movable part of the fixture are turned by a certain angle and moved by a certain distance in turn, and then the next surface is processed. , until all the processing content is completed. The indexing device can concentrate the process of the workpiece, so it is widely used in turning, drilling, milling and other processing. the

Existing indexing devices include hand-pull type positioners, gun column type positioners, and rack and pinion operating mechanisms. These indexing devices have complex structures and cumbersome operations.

Contents of the invention

The technical problem to be solved by the utility model is how to provide an indexing device with simple structure and convenient use.

In order to solve the above technical problems, the utility model provides an indexing device, comprising: a fixture base, a positioning mandrel and an indexing plate, the fixture base is provided with a horizontal workbench; the indexing plate passes through the positioning core The axis is connected with the horizontal workbench, and can rotate around the positioning mandrel in the horizontal direction; the positioning mandrel has a connecting end protruding from the upper part of the demeanor plate, which is used to fasten the workpiece; The dial is provided with a plurality of positioning holes equally distributed, and the horizontal workbench is provided with a threaded positioning pin for screwing into the positioning holes and fixing the indexing plate.

Preferably, the connecting end is provided with a screw thread or a fastening nut matched with the workpiece for fastening the workpiece.

Preferably, the horizontal worktable is connected to the positioning bolt through a bush.

Preferably, it also includes a drill template arranged above the horizontal workbench, and the drill template is provided with an anti-wear bushing and a quick-change drill sleeve. the

The indexing device has a simple structure and no precision parts such as gears or worms, but it is more convenient to use. Turn the indexing plate to align the positioning holes with the positioning pins, and then insert the pins to complete an indexing.

Description of drawings

Fig. 1 is a schematic diagram of an indexing device of the present invention.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

A kind of indexing device of the present utility model as shown in Figure 1, comprises: fixture base 1, positioning mandrel 2 and index plate 3, and fixture base 1 is provided with horizontal workbench 101; Index plate 3 passes through positioning mandrel 2 is connected with the horizontal workbench 101, and can rotate around the positioning mandrel 2 in the horizontal direction; the positioning mandrel 2 has a connecting end 201 protruding from the upper part of the bearing plate 3, and the connecting end 201 is provided with a screw thread or The fastening nut is used to fasten the workpiece 4; the index plate 3 is provided with a plurality of positioning holes 301 equally distributed, and the horizontal workbench 101 is provided with a threaded positioning pin 102 for screwing into the positioning holes 301 and fixing Dial 3.

In order to prevent the indexing device from wearing out too quickly, the horizontal table 101 is connected with the positioning pin 102 through the bushing 103 .

In order to facilitate tool replacement, the indexing device also includes a drill template 104 located above the horizontal workbench 101. The drill template 104 is provided with an anti-wear bushing 105 and a quick-change drill sleeve 106 for assembling the cutter. the

The indexing device has a simple structure and no precision parts such as gears or worms, but it is more convenient to use. Turn the indexing plate to align the positioning holes with the positioning pins, and then insert the pins to complete an indexing.

The above embodiments are only used to illustrate the utility model, but not to limit the utility model. Those of ordinary skill in the relevant technical fields can also make various changes and modifications without departing from the spirit and scope of the utility model. , so all equivalent technical solutions also belong to the category of the utility model, and the patent protection scope of the utility model should be defined by the claims.
