Abstract
Description
Technical Field This utility model relates to the field of drilling and tapping machinery, specifically a special machine tool for drilling holes in the counterweight plates of a strength training fitness device. Background Technology
[0001] The weight plate of the strength training machine has three through holes for mounting the selection bar. The traditional processing method is to use ordinary machine tools to drill and bore the holes one by one. The disadvantages are low work efficiency and poor drilling accuracy. Utility Model Content
[0002] This utility model addresses the problems of low efficiency and poor precision in machining through holes for counterweight plates of strength training devices using ordinary machine tools by providing a machine tool that can complete three combined drilling and boring operations in one go for the processing of counterweight plates for strength training devices.
[0003] The technical solution of this utility model is a drilling machine for counterweight plates of a strength fitness machine. Its special feature is that a longitudinal tooling plate is installed on the left side of the square worktable, and right-positioned molds are installed on the front and rear sides of the right side of the tooling plate. Side positioning blocks are installed on the inner side of the molds, and a lower positioning block is installed on the lower part of the inner side of the side positioning blocks. A clamping oil cylinder is installed on the inner side of the lower positioning block.
[0004] The middle of the worktable is equipped with two longitudinally arranged transverse guide rails, on which transverse slides are mounted. A transverse lead screw is mounted in the middle below the transverse slides, and a feed motor is mounted on the right end of the transverse lead screw. The feed motor is fixed to the right side of the worktable.
[0005] The right side of the horizontal slide plate is equipped with a motor mount, and the motor mount is equipped with a horizontal main spindle motor. The left side of the horizontal slide plate is equipped with a multi-spindle unit, and a synchronous belt is installed between the multi-spindle unit and the main spindle motor. Three U-shaped drill bits are installed on the left side of the multi-spindle unit, and boring tools are installed on the rear half of the U-shaped drill bits. Mold closing sleeves corresponding to mold closing are installed on the front and rear sides of the multi-spindle unit.
[0006] During operation, the weight plate of the strength training machine to be processed (hereinafter referred to as the workpiece) is first installed between the side positioning block and the lower positioning block on the tooling plate. The clamping cylinder is started to clamp the workpiece from the right side. Then the feed motor is started, and through the cooperation of the transverse screw and the transverse slide, and the transverse slide and the transverse guide rail, the motor base, the main spindle motor, the multi-spindle, and the U-drill bit are pushed to the left. When the U-drill bit approaches the workpiece, the feed motor switches to the working speed. At this time, the mold sleeve and the mold close. The main spindle motor starts and drills the workpiece through the three U-drill bits on the multi-spindle driven by the synchronous belt. After the front half of the U-drill bit passes through the workpiece, the boring tool on the rear half of the U-drill bit performs boring processing on the drilled hole.
[0007] The technical effect of this utility model is that, by adopting the above technical solution, a machine tool for drilling holes in the counterweight plates of a strength training device can be realized. Since the workpiece is clamped at one time, three through holes are drilled and bored at the same time, which not only speeds up the work efficiency but also improves the processing accuracy.
