Because its shape looks like a tower, it is also called "pagoda tooth".

[0003] At present, the intermediate shaft product needs to be processed by a thread rolling machine.

Embodiment

[0025] The present application will be described in detail below in combination with specific examples. In the present technical solution, the component model, material name, connection structure, control method, algorithm and other features not explicitly described are considered as common technical features disclosed in the prior art.

[0026] The multi-station automatic processing method for intermediate shaft in the present application constructs a fully automatic processing flow. Through fully automatic coded feeding, forward and reverse adjustment, automatic work position translation and carrying, coded information adding and corresponding processing entry, a safe and efficient intermediate shaft processing process is realized, including the following steps:

[0027] S1: The intermediate shafts to be processed are placed one by one in the forward and reverse detection station, and the intermediate shafts to be processed are numbered to establish the intermediate shaft code. An infrared sensor is provided at the discharge port of the hopper feeder. The feeding interval of the hopper feeder is 1-5s. The single-chip microcomputer reads the level signal of the infrared sensor. When the intermediate shaft is discharged from the discharge port of the hopper feeder, the single-chip microcomputer establishes an intermediate shaft code. The hopper feeder performs forward and reverse disordered automatic feeding, and the intermediate shafts are placed one by one in the forward and reverse detection station. The technical solution is extremely convenient for automatic storage and feeding mode, overcomes the disadvantages of disordered storage and difficult automatic processing, and through multi-sensor detection and automatic addition of detection information, a precise and targeted processing process is given.

[0028] S2: The forward and reverse detection is performed by the laser sensor on the forward and reverse detection station, and the direction error intermediate shaft is rotated 180° by the translation manipulator, and then the intermediate shaft is moved to the taper hole detection station.

[0029] In specific implementation, the forward and reverse detection station is provided with an electric cylinder, and the tail end of the laser sensor is connected with the output rod of the electric cylinder. The electric cylinder translates the laser sensor through the reciprocating extension and retraction of the lifting rod, so as to realize the flat scanning ranging of the laser sensor on the intermediate shaft, and realize the judgment of the forward and reverse directions of the intermediate shaft through the flat scanning ranging data. The flat scanning ranging refers to comparing the multiple point distances obtained in the flat scanning process with the standard data to obtain the forward and reverse information. The flat scanning ranging data obtained by the laser sensor is analyzed by the single-chip microcomputer, and compared with the preloaded standard data to obtain the forward and reverse placement result. If the result is reverse, the single-chip microcomputer instructs the translation manipulator to rotate 180°.

[0030] S3: The contact type displacement sensor on the taper hole detection station detects the taper hole depth of the intermediate shaft, and at the same time, detects the length of the intermediate shaft. Then, the single-chip microcomputer adds the taper hole depth information and the intermediate shaft length information to the code of each intermediate shaft.

[0031] In specific implementation, the taper hole detection station is provided with a contact type displacement sensor. The taper hole depth information and the intermediate shaft length information obtained by the contact type displacement sensor are read by the single-chip microcomputer, and the information is added to the corresponding intermediate shaft code. Then, the single-chip microcomputer sends the intermediate shaft code to the thread rolling processing equipment, so as to be used for targeted processing of the thread rolling processing equipment. The inside of the contact type displacement sensor is composed of a core, a coil framework, a primary coil and a stimulating coil. During the measurement process, the core moves left and right in the coil framework, but does not contact any internal instrument elements, and completes frictionless measurement. In specific implementation, an inductive displacement sensor, i.e. LVDT displacement sensor, is selected, which measures the taper hole depth information and the intermediate shaft length of the product by using the principle of electromagnetic induction. In specific implementation, the measurement can be performed in cooperation with a mechanical arm, because this is a mature existing technology in the industry, which will not be described here.

[0032] S4: The thread rolling processing equipment loads the intermediate shaft codes of each intermediate shaft according to the processing sequence, so as to read the parameter information of each intermediate shaft for corresponding processing. The translation manipulator grabs the intermediate shaft to the thread rolling processing equipment for processing, and obtains the intermediate shaft finished product.

[0033] S5: The translation manipulator places the intermediate shaft finished product on the oil blowing station for oil blowing, and then conveys and stores the intermediate shaft finished product after oil blowing.

It is not intended to be exhaustive or to limit the application to the precise form disclosed. Modifications and variations are possible in light of the above teachings or can be acquired from practice of the application.
