Automobile engine cylinder cover intelligent production line and technological process thereof

Abstract

The invention discloses an automobile engine cylinder cover intelligent production line and a technological process thereof. The automobile engine cylinder cover intelligent production line overcome the problem that the prior art cannot adapt to continuously changing product transformation production, and is characterized in that a blank workpiece model recognition mechanism is installed at the start end of a machining center unit, a marking machine, a feeding and detecting mechanism and an SPC measuring station are installed at the terminal of the machining center unit, a cleaning machine, ameasuring machine, a press-fitting machine and an auxiliary appearance inspection mechanism are arranged on a PZR material channel; the technological process comprises the following steps that the blank workpiece is fed, the blank workpiece model is identified, the blank workpiece is machined into a semi-finished workpiece, the semi-finished workpiece is cleaned, the semi-finished workpiece is measured, and the semi-finished workpiece is subjected to press fitting and the appearance is inspected. The automobile engine cylinder cover intelligent production line and the technological process thereof has the beneficial effects that the model switching is carried out through a quick-change mechanism, so that the wire-mixing production of the multiple-model cylinder cover is realized, the repeated positioning precision of 0.003 mm can be realized, after a sub-board is replaced, adjustment and compensation of parameters do not need to be carried out, the production state can be normally entered, and the technological process is suitable for the requirement of continuously changing product transformation production.

Description

technical field [0001] The invention belongs to the technical field of automated production lines, and in particular relates to an intelligent production line for an automobile engine cylinder head and a process flow thereof. Background technique [0002] The engine is the heart of the car, and the cylinder head is one of the key parts in the heart. The quality of the cylinder head determines the performance of the engine. In the prior art, most of the cylinder heads of automobile engines are processed by machining center machine tools or special machine tools. In this case, manual loading and unloading is usually used. Manually transport the cylinder head to another machine tool or machining center for processing, the handling efficiency is low, the production cycle is slow, the labor cost is high, and it is easy to cause scratches on the surface of the cylinder head and affect the surface quality of the cylinder head. Due to the large batch size and high precision require...

Problems solved by technology

First of all, the production line system described in this invention does not conform to the conventional production process of automobile engine cylinder heads. Secondly, after careful analysis of the instructions of this invention, it can be seen that this invention is actually just a simple automatic production line. The four processes of outer circle, corrected turning, semi-finishing and finishing water channel are processed, while another row of equipment is used for boring inner hole, fine boring inner hole, rough honing and screw parachute honing. There is a transfer area, and a joint walking robot is set next to each processing module. There are several parts temporary storage areas in the transfer area, and a transmission device is set between the parts temporary storage areas. The processing module and the transfer between the processing module and the component temporary storage area, the processed parts are transferred between different component temporary storage areas through the transmission device, so the flexibility of the production line system is obviously insufficient, and its host is still specially based on a certain part of the processed workpiece. The process design is actually a relatively rigid automatic line. In addition, when the processed parts are temporarily reworked and need to be transported across the parts temporary storage area, the transmission is carried out through the transmission bypass, and the transmission bypass is only set at There is no transfer bypass between other processes between the fine boring inner hole module and the fine turning water channel module with a high repetitive processing rate, and it can only be transferred by the component transfer area, which affects the production cycle and low production efficiency

Further analysis of the description of the invention shows that the automatic production line system of the invention lacks the detection, cleaning and quality analysis in the conventional production process of the automobile engine cylinder head, and lacks the workpiece model for the entry of blank workpieces or semi-finished workpieces and product workpieces. The judgment of whether it meets the requirements of the system objectives cannot adapt to the ever-changing product transformation production and product quality assurance
