Description

Simple indexing device

Technical Field

The utility model belongs to the technical field of machining, especially, relate to a simple and accurate indexing, simple and easy indexing means of simple operation efficient.

Background

The conditions that petals, platforms, grooves and the like are uniformly machined on the excircle of a part are common in the field of machinery, generally, small parts are provided with purchased dividing heads, and large parts are not provided with proper clamping tools, so that the cost is high if the large parts are customized.

Disclosure of Invention

An object of the utility model is to overcome exist among the prior art not enough and provide one kind can link to each other with the part to through rotating the simple and easy indexing means that part graduation processing was realized to the indexing platform that part alignment itself had.

The technical scheme of the utility model is realized like this:

a simple indexing device is characterized in that: the simple indexing device is provided with an indexing platform which is processed and is consistent with the part to be processed, the part to be processed is processed through the indexing platform, and after the simple indexing device is connected with the part to be processed into a whole through a threaded spigot or an end face connecting hole, a processing clamping datum which is unified with the part to be processed is processed on the simple indexing device. The simple indexing device is provided with a rotating pin hole, and the simple indexing device and the part to be machined rotate by the rotating pin hole to realize the machining indexing of the part to be machined. One end of the simple indexing device is provided with a boss inserted into an inner hole of a part to be machined, the excircle of the boss is provided with threads, the inner hole of the part to be machined is provided with threads, the boss is in threaded connection with the inner hole of the part to be machined, and the end face of the part to be machined is in contact with the end face of the simple indexing device outside the boss of the simple indexing device for positioning. The contact end surface between the simple indexing device and the part to be processed is provided with connecting holes for connecting the simple indexing device and the part to be processed; the excircle of the simple indexing device has the same size with the part to be processed. The simple indexing device and the part to be processed are provided with connecting holes on the contact end face between the simple indexing device and the part to be processed.

The technical scheme of the utility model the positive effect that produces as follows: the indexing is simple and accurate, the manufacturing cost is low, and the operation is convenient and efficient.

Detailed Description

As shown in fig. 1, 2, 3 and 4, the simple indexing device 2 is provided with an indexing platform 6 which is processed and is consistent with a part 1 to be processed, the part 1 to be processed is processed through the indexing platform 6, after the simple indexing device 2 is connected with the part 1 to be processed into a whole through a threaded spigot or an end face connecting hole, a processing clamping datum which is unified with the part 1 to be processed is processed on the simple indexing device 2.

The simple indexing device is provided with a rotating pin hole 7, and the simple indexing device and the part 1 to be machined rotate by the rotating pin hole 7 to realize the machining indexing of the part 1 to be machined.

One end of the simple indexing device 2 is provided with a boss 5 inserted into an inner hole of a part to be machined, the outer circle of the boss 5 is provided with a thread 4, the inner hole of the part 1 to be machined is also provided with a thread, the boss is in threaded connection with the inner hole of the part to be machined, and the end face of the part 1 to be machined is in contact with the end face 8 of the simple indexing device outside the boss of the simple indexing device 2 for positioning.

The contact end surface between the simple indexing device 2 and the part 1 to be processed is provided with connecting holes for connecting the simple indexing device and the part; the excircle of the simple indexing device has the same size with the part to be processed.

Firstly, according to the characteristics of a part 1 to be processed, processing a part (such as a thread 4, a spigot, a hole and the like) connected with the part 1 to be processed on a simple indexing device 2, then connecting the simple indexing device 2 with the part 1 to be processed, assembling in place, processing an excircle with the part 1 to be processed as a clamping reference 3, removing the simple indexing device 2, processing an indexing platform 6 which is the same as the part 1 to be processed on the simple indexing device 2 by taking the excircle and the end surface processed by the simple indexing device 2 as references, processing a rotating pin hole 7 (used for rotating the part), then connecting with the part 1 to be processed again, reassembling in place, aligning and fixing the part 1 to be processed on a central processing table of the simple indexing device 2 and the part 1 to be processed by using a V-shaped block and a pressing plate, aligning and aligning a first indexing platform on the simple indexing device 2 by using a lever dial indicator, and then, starting to process each size of the indexing part on the part according to the drawing requirement, namely, processing the size of the indexing part on the part by taking the indexing platform 6 on the processed simple indexing device 2 as a reference, after one processing surface is processed, rotating the part 1 to be processed and the simple indexing device 2 together, aligning the second indexing platform 6 on the simple indexing device 2, processing the second indexing platform 6 on the part after alignment, and so on, thereby realizing the indexing processing of all the indexing parts of the part. In the figure 3, the parts and the tooling which are assembled together are machined on a lathe to form an excircle with the same size as a clamping position of a clamping reference.

Simple graduation can be realized through the use of this device, and the graduation is accurate, and the cost is lower.
