Automatic honing device and machining method

Abstract

The invention relates to an automatic honing device. The automatic honing device comprises a machine body, a control cabinet connected with the machine body and a grinding device connected with the control cabinet and further comprises a touch panel in electric connection with the control cabinet, wherein the grinding device comprises a lifting device, a fixing support plate, a first grinding component, a second grinding component, tool support seats and a partitioning component; the fixing support plate is connected onto the chain of the lifting device; the lifting device drives the fixing support plate to ascend and descend through the transmission of a precision ball screw; the first grinding component and the second grinding component are fixed on the fixing support plate; the tool support seats are fixed on a rotating disc; the rotating disc is connected with the partitioning component; and the partitioning component is fixed on the machine body. The invention further provides a machining method. According to the automatic honing device and the machining method, a plurality of honing blades with different roughness are utilized to machine a cylinder workpiece in sequence, and with the combination of the automatic control device, the cylinder workpiece is honed automatically, the final machining precision is ensured to be 2 [mu]m or below, the precision is high, and the speed is high.

Description

technical field [0001] The invention relates to a honing machine tool, in particular to a numerically controlled honing machine tool. Background technique [0002] Honing is the finishing process of the finished surface with the oilstone (also called honing stick) embedded in the honing head. The contact area between honing and the hole surface is larger, and the processing efficiency is higher. The honing machine is a grinding machine that uses a honing head to honed the surface of the workpiece, and is mainly used in the manufacturing industry to honed the holes of the workpiece. There are two types of honing machines: vertical and horizontal. The vertical honing machine has a short working stroke of the spindle and is suitable for honing cylinders and box holes. [0003] The existing honing equipment is mainly a single-knife device. Even if it is an automated equipment, it can only process one workpiece at a time.

Problems solved by technology

[0003] The existing honing equipment is mainly a single-knife device. Even if it is an automated equipment, it can only process one workpiece at a time. It needs manual reciprocating handling and transfer each time. After completing one process, the next process is performed, which is not efficient. Sometimes the grinding tool is replaced due to the size adjustment of a batch of workpieces. After one process in honing is completed, the workpiece is transferred to the next equipment for the next process. Although the processing accuracy is guaranteed in this way, the sales volume is obviously slow , and increases the workload of workers
