Description

Tool magazine door for machining center

technical field

The invention relates to a tool magazine door, in particular to a tool magazine door for a machining center.

Background technique

The tool magazine door is a very critical part of the protection of the entire tool magazine system. It can be opened automatically when the spindle tool is changed, and it can prevent dust, water and iron filings after closing.

At present, the structure of the commonly used tool magazine door mainly includes several forms such as side pull, pull up and flip. When the cylinder and guide rail or linear guide rail are used for driving and guiding alone, due to the splash of coolant and iron filings in the process, It cannot be completely sealed, so that the coolant or fine iron filings seep into the tool magazine, which affects the life and machining accuracy of the tool.

Contents of the invention

The technical problem solved by the present invention is to overcome the deficiencies of the prior art, and provide a tool magazine door for a machining center that occupies less space and has a short tool change stroke.

The technical solution adopted by the present invention is that the tool magazine door is used in the machining center, the cylinder and the guide rail are fixed on the machine tool protection, the cylinder is hinged to the connection plate, the connection plate is fixed on the protection plate, and the protection plate is fixedly connected with the slide seat of the guide rail and the lower end of the hinge. The block is fixed on the tool magazine door by the support, the bearing support is fixed on the machine tool protection, the bearing is fixed on the bearing support through the pin shaft, the upper end of the hinge is fixed to the tool magazine door, and the upper end of the hinge and the lower end of the hinge are respectively hinged with the connecting lever. One end of the spring is connected with the tool magazine door, and the other end is connected with the protective plate.

When it is necessary to change the tool, the piston rod of the cylinder stretches out, driving the protective plate to move to the right, the lower end of the hinge moves to the right with the protective plate, and drags the long plate at the same time, drives the upper end of the hinge, the stopper moves linearly on the bearing surface, and the spring starts Contraction, under the combined action of the long plate and the spring, the upper end of the hinge drives the tool magazine door to move backward, the tool magazine door opens, the piston rod continues to extend, and the tool magazine door is fully opened. When the tool change is over, the piston rod of the cylinder retracts, driving the protective plate to move to the left, and at the same time, the door of the tool magazine moves to the left. Under the action, the upper end of the hinge drives the tool magazine door to move forward, and the tool magazine door is closed. This structure can complete the quick opening and closing of the tool magazine door through the combined force of the upper hinge and the lower hinge, the long plate and the spring, and at the same time saves tool changing time and occupied space.

There are 45°flanges on the left and right sides of the tool magazine door. When the door is closed, the flanges of the tool magazine door are closely combined with the machine tool protection. The inner wall of the door flows back to the inside of the machine tool, which improves the sealing of the tool magazine door.

The beneficial effect of the present invention is that the present invention has simple structure, is suitable for small-scale machining centers with limited space, has low noise, good self-sealing performance, and saves tool changing time to a large extent.

detailed description

The present invention will be further described below in conjunction with accompanying drawing. Fig. 1 is a front view when the tool magazine door of the machining center of the present invention is closed, and Fig. 2 is a bottom view of Fig. 1 . The machining center uses the tool magazine door, the cylinder 1 and the guide rail 2 are fixed on the machine tool protection 3, the cylinder 1 is hinged to the connection plate 4, the connection plate 4 is fixed on the protection plate 5, and the protection plate 5 is fixed to the guide rail slide seat 6 and the lower end of the hinge 7 connection, the block 8 is fixed on the tool magazine door 10 by the support 9, the bearing support 11 is fixed on the machine tool protection 3, the bearing 12 is fixed on the bearing support 11 through the pin shaft 13, and the hinge upper end 14 is connected with the tool magazine door 10 Fixed, the hinge upper end 14 and the hinge lower end 7 are respectively hinged with the long plate 16, one end of the spring 15 is connected with the tool magazine door 10, and the other end is connected with the protective plate 5.

When it is necessary to change the tool, the piston rod of the cylinder 1 stretches out, driving the protective plate 5 to move to the right along the guide rail 2, the lower end of the hinge 7 moves to the right with the protective plate 5, and drags the long plate 16 at the same time, and the stopper 8 is on the bearing 12 The surface moves in a straight line, and the spring 15 begins to shrink. Under the joint action of the long plate 16 and the spring 15, the upper end of the hinge 14 drives the tool magazine door 10 to move backward, the tool magazine door 10 opens, and the piston rod of the cylinder 1 continues to extend, and the tool magazine The door 10 is fully open. When the tool change is over, the piston rod of cylinder 1 retracts, driving the protective plate 5 to move to the left, and at the same time, the tool magazine door 10 moves to the left. When the stopper 8 touches the bearing 12, it moves linearly on its surface, Under the combined action of the plate 16 and the spring 15, the hinge upper end 14 drives the tool magazine door 10 to move forward, and the tool magazine door 10 is closed. This structure can complete the quick opening and closing of the tool magazine door through the combined force of the upper hinge and the lower hinge, the long plate and the spring, and at the same time saves tool changing time and occupied space.

There are 45°flanges on the left and right sides of the tool magazine door. When the door is closed, the flanges of the tool magazine door are closely combined with the machine tool protection. The inner wall of the door flows back to the inside of the machine tool, which improves the sealing of the tool magazine door.

The tool magazine door for machining centers of the present invention has a simple structure, is suitable for small machining centers with limited space, has low noise, good self-sealing performance, and saves tool changing time to a large extent.
