Description

Technical Field

[0001] The invention belongs to the technical field of machine tool fixtures, and in particular relates to a special device for machining a tool box of a lathe. Background Art

[0002] The traditional processing method of the lathe tool box hole system adopts universal processing, that is, the processing surface is used as the reference on the boring machine workbench to align and compact, and then the hole system is bored. During the boring process, after the first hole system is processed, the hole distance needs to be calibrated before the second hole system can be processed. This method has certain disadvantages. First, it is time-consuming and laborious for workers to install the card during the processing process, and the workpiece reference needs to be aligned, which is uncertain and inefficient. Secondly, after processing one hole, the operator needs to calibrate the hole distance when processing another hole. When ensuring the geometric tolerances such as hole distance and hole diameter, it is affected by various factors such as machine tools and operating methods, resulting in dimensional deviation, especially when the workpiece needs to be turned around for processing, which increases the difficulty of workpiece processing and the quality of the box processing cannot be guaranteed. Third, during the entire process of processing parts, the operator needs to install the drawing process requirements to select reasonable processing references and cutting parameters. At the same time, the operator is also required to use measuring tools to measure the workpiece, so the operator's own technical level is required to be high. Summary of the invention

[0068] After the adjustment of the support platform 2-4 is completed, the tool box is fixed. Specifically, the tool box is placed on the support platform 2-4. In order to facilitate the smooth movement of the tool box on the support platform 2-4, two long strip-shaped pads can be set on the support platform 2-4, and the tool box is placed on the pads; first, the two ends of the tool box are preliminarily fixed. Specifically, one end of the tool box is against the fixed end stop 10-1, and then the adjusting screw 10-2 is rotated to abut against the other end of the tool box; after the two ends of the tool box are preliminarily fixed, the tool box is preliminarily positioned laterally. Specifically, one side of the tool box is against a side positioning bolt 9-2 , by rotating the side positioning bolt 9-2, the axis line of the end hole system of the tool box is made to be in line with the axis line of the sleeve 13, and then the other two side positioning bolts 9-2 are adjusted to press against the other side of the tool box to achieve preliminary lateral fixation of the tool box; finally, tighten the adjusting screw 10-2 and the side positioning bolt 9-2 to fix the tool box in the horizontal direction; after horizontal fixation, flip the connecting rod 8-2 to drive the pressure cover 8-5 to cover the tool box, flip the screw 8-3 and keep it vertical, rotate the third nut 8-4 and press the connecting rod 8-2, at this time, the pressure cover 8-5 presses the upper side of the tool box to achieve longitudinal fixation.

[0070] During boring: the gearbox 18 drives the boring bar 14 to rotate, and the boring bar 14 also drives the sliding sleeve 13 to feed relative to the boring die frame 11 until the hole system processing at one end of the tool box is completed; after the boring of one end of the tool box is completed, the connection between the boring bar 14 and the output shaft of the gearbox 18 is released, and the restrictions on the support platform 2-4 by the angle positioning assembly 3 and the high positioning assembly 4 are released; the support platform 2-4 is rotated 180°, and the support platform 2-4 is fixed again by the angle positioning assembly 3 and the high positioning assembly 4; the gearbox 18 is connected to the corresponding boring bar 14, and the boring bar 14 is used to drive the hole system processing at the other end of the tool box. During the tool box processing, the rotatable characteristics of the support platform 2-4 make it unnecessary for the tool box to be disassembled for positioning for the second time, which can effectively improve the tool box processing efficiency and reduce the difficulty of processing operations; the angle positioning assembly 3 and the high positioning assembly 4 provide guarantees for the stability and positioning accuracy of the support platform 2-4, which is conducive to improving the processing quality of the workpiece.
