Abstract
The utility model relates to a pneumatic pull rod of a strong tool changer, which comprises a shell, wherein the bottom of the shell is fixed onto a chassis, the top of the shell is equipped with an upper end cap, a valve connector is arranged on the outer side wall in the middle of the shell, a connection bar, a guide post and a fan blade are disposed inside the shell, a cam is fixed on the connection bar, the guide post is arranged on one side of the cam, the guide post is engageably fixed with the cam, the fan blade is disposed on the upper portion of the connection bar, the upper end of the fan blade is equipped with an upper end bearing, and the lower end of the fan blade is provided with a lower end bearing and fixed onto the connection bar through a lower end cap. The pneumatic pull rod of a strong tool changer has the advantages of fast retracting, stable running, precise structure and low fault rate. Further, the pneumatic pull rod of a strong tool changer only needs 3 seconds to change tools, has a changing speed more than 10 times of a traditional tool, greatly improves production efficiency, can guarantee the precision of a main shaft without striking the pull rod, and prolong the service life of a bearing the main shaft. When the pneumatic pull rod is used, the main shaft is not required to be shifted to lower gears or fixed, and the pneumatic pull rod can be used in neutral position and has high security.
Description
Technical field
The utility model relates to the tool changing device of Digit Control Machine Tool, relates in particular to a kind of pneumatic pull bar of strong tool changing device.
Background technology
Tool changing device is the key position on the Digit Control Machine Tool, and the length of its tool change time directly has influence on the processing beat of lathe, is that whether the judge lathe is efficient, an important indicator at a high speed.The tool changing mode of present Digit Control Machine Tool, roughly be divided into manipulator tool changing and no manipulator tool changing, its principle be by cylinder and oil cylinder come manipulator robot or drive tool magazine lifting, move to realize automatic tool changer, tool changing is to need main shaft not only to move horizontally, and move up and down, need attachedly grab or cushion tool magazine during tool changing and assist tool changing, tool-changing speed is slow, occurs cutter easily and grabs situations such as not firm, that fault rate is high, easily come off.
The utility model content
The purpose of this utility model provides a kind of pneumatic pull bar of strong tool changing device, need when overcoming existing tool changing device tool changing attachedly grab or cushion tool magazine and assist tool changing, tool-changing speed is slow, occurs the deficiency that cutter is grabbed situation such as not firm, that fault rate is high, easily come off easily.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of pneumatic pull bar of strong tool changing device, comprise housing, described housing bottom and chassis are fixed, and case top is provided with upper end cover, on the lateral wall at housing middle part, be provided with the vapour lock joint, the inside of housing is provided with connecting rod, guide pillar and fan blade, wherein is fixed with cam on the connecting rod, and a side of cam is provided with guide pillar, guide pillar cooperates fixing with cam, described fan blade is located at the top of connecting rod, and the upper end of fan blade is provided with the upper end bearing, and the lower end of fan blade is provided with bottom end bearing and fixes by bottom end cover and connecting rod.
The beneficial effects of the utility model are: withdrawing is quick, stable action, overall structure precision, fault rate is extremely low, change cutter and only need 3 seconds, be conventional tool speed more than 10 times, greatly improved production efficiency, need not to beat the precision that pull bar can be protected main shaft, and the service life of prolongation main shaft bearing, when this machine used, main shaft need not change in low gear or fixed main shaft, can use in neutral gear, safe.
