Description

Vertical multi-jaw clamping device for processing machines

technical field

The utility model relates to a mechanical fixture, in particular to a vertical multi-claw chuck capable of converting a multi-claw chuck used for a horizontal processing machine into a vertical multi-claw chuck used for a vertical processing machine. the

Background technique

The main function of the fixture is to hold the workpiece so that the tool of the processing machine can be used for turning, milling, drilling, etc. metal processing. Generally, traditional machining machines are divided into two categories: vertical processing machine and horizontal type according to the type of tool spindle. That is to say, if the tool spindle stands vertically, it is vertical, such as milling machine, drilling machine, etc. If the tool spindle is horizontal and flat, it is a horizontal processing machine, such as a lathe...etc. However, both vertical and horizontal processing machines are equipped with special fixtures. For example, vise is usually used in milling machines and drilling machines, while multi-jaw chucks are often used in lathes. In particular, the multi-jaw chuck further includes a self-aligning center chuck, commonly known as a three-jaw chuck. When the three-jaw chuck is used for lathe processing, as long as its three claws hold a round bar , the round rod is automatically aligned with the center of its rotating spindle without troublesome center correction, which is convenient for cutting and is quite simple. the

Therefore, there are manufacturers who apply the three-jaw chuck to an existing clamping structure 9 on a drilling machine, as shown in FIG. It is disclosed that a group of three-jaw chucks 91 are installed on the processing table 94 of a driller, and the three-jaw chucks 91 are fixed on the processing table 94 by means of multiple groups of pressing blocks 92, and the three-jaw chucks are fixed during the installation process. The collet 91 is fixed on the preset position of the processing table 94, and the claw 911 of the three-jaw chuck 91 can automatically align the round rod workpiece to a preset center during the process of clamping the round rod workpiece, so that Drilling can be carried out. When the drilling is completed and the next round rod workpiece is to be drilled, the three-jaw chuck 91 is released and the next round rod workpiece is put into the clamping hole, so that the center of the round rod workpiece does not need to be corrected one by one. At the preset position, the existing clamping structure 9 is very suitable for mass production. the

However, in the above-mentioned existing clamping structure 9, when clamping or loosening the claws 911 of the three-jaw chuck 91, a T-shaped handle 93 must be inserted into a claw adjusting knob 912, and then rotated This T-type handle 93 just can work, but this T-type handle 93 becomes horizontal at this moment, and the horizontal handle bar 931 of this T-type handle 93 can interfere with processing table 94, and this T-type handle 93 can't be done 360 degree rotations, Quite unfavorable for the operations such as the clamping, loosening of its claw not 911 that technician applies force to operate. the
