Description

Inner hole boring machine Technical Field An inner hole boring machine belongs to the technical field of boring machines. Background The boring machine is a machine tool for boring the existing prefabricated holes of the workpiece by using a boring cutter. Typically, boring tool rotation is the primary motion and movement of the boring tool or workpiece is the feed motion. The method is mainly used for machining high-precision holes or finishing the finish machining of a plurality of holes by one-time positioning, and can be used for machining other machining surfaces related to hole finish machining. The drilling, milling and cutting can be performed by using different cutters and accessories, and the machining precision and the surface quality of the drilling and milling machine are higher than those of a drilling machine. When producing the single hydraulic prop, the cylinder body of the single hydraulic prop needs to be subjected to turning of an outer circle and boring of an inner hole, wherein the turning of the outer circle is usually performed by a lathe, and the boring of the inner hole is performed by a boring machine. When boring the cylinder body through the boring machine, need press from both sides tightly the cylinder body, the boring machine makes the boring bar rotate relatively with the cylinder body between, and then bore the cylinder body through the boring cutter on the boring bar, need take off the boring cutter on the boring bar earlier after boring is accomplished, just can reset the boring bar and reset with the cylinder body after the boring cutter takes out, when boring the next cylinder body, need install the boring cutter of taking off on the boring bar again to realize the boring operation of moving down the cylinder body. At present, the boring cutter is taken out and put in through manual operation, namely, a worker installs the boring cutter on a boring bar before boring, after boring is completed, the worker needs to stretch hands into the boring bar to take out and put in the boring cutter, and because the clearance between the boring cutter and a boring cutter hole on the boring bar is small, the boring cutter needs to be aligned with the boring cutter hole when put in, and the boring cutter can be put in the boring cutter hole, so that the boring cutter is inconvenient to operate, the boring cutter temperature is high after boring, the worker is easy to scald, and the potential safety hazard is high. In addition, when boring the cylinder body, the existing boring machine clamps the cylinder body through one end of the cylinder body, and because the length of the cylinder body is long, when clamping the cylinder body, the boring rod and the cylinder body are difficult to ensure to be coaxial, so that the positioning difficulty of the cylinder body is high, the precision of the machined cylinder body is unstable, and the clamping speed of the cylinder body is low, so that the machining efficiency of the cylinder body is low. Disclosure of Invention The invention aims to solve the technical problems of overcoming the defects of the prior art and providing the inner hole boring machine which is used for positioning two ends of a cylinder body and clamping the cylinder body through the two ends of the cylinder body so that the cylinder body is positioned accurately and the clamping speed is high. The inner hole boring machine is characterized by comprising a driving device, a pressing device, a boring bar and a feeding device, wherein the driving device is arranged at intervals and opposite to the pressing device, a space for accommodating a workpiece is formed between the driving device and the pressing device, positioning parts are arranged on the inner side of the driving device and the inner side of the pressing device, through holes for the boring bar to pass through are formed in the pressing device or the driving device, the feeding device is connected with the boring bar, and the feeding device drives the boring bar to axially move. Preferably, the positioning part comprises an active supporting disc and a passive supporting disc, the active supporting disc is arranged on the driving device and synchronously rotates along with the driving device, the passive supporting disc is rotatably arranged on the pressing device, through holes are formed in the active supporting disc and the passive supporting disc, and positioning openings with the inner diameter larger than that of the outer end are formed in the inner end of the active supporting disc and the inner end of the passive supporting disc. The two ends of the cylinder body are respectively positioned in the positioning openings, the cylinder body is pressed on the driving support plate by the pressing device through the driven support plate, so that the clamping of the cylinder body is realized, the positioning reliability of the cylinder body is ensured through the positioning of the two ends of the cylinder body,
