Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic tool changer and other arrangements of a ram horizontal machining center, and more particularly, to the freedom of a moving column by devising the position of an automatic tool changer and the position of an elevating motor. The present invention relates to a device having improved degree and maintainability of a jig.

[0002]

2. Description of the Related Art Conventionally, the mounting position of an automatic tool changer in a horizontal ram machining center or the like is directly above a machining area. This is to ensure a short and stable operation of changing the weight of the machine tool and changing the tool mounted on the spindle on the moving column.

However, since the mounting position of the automatic tool changer is just above the machining area in the horizontal machining center of the ram, the automatic tool changer is arranged right above the jig, so that the jig is not easy to maintain. According to the gantry loader, there is a problem that the work cannot be loaded from above. Further, a support upright from the bed is supported directly above the moving column, and an automatic tool changer is mounted on this support base plate, and when the moving tool is brought close to the top of the moving column, both members interfere with each other. There is a problem. In particular, there is a problem that an elevating motor that moves a quill having a main shaft up and down collides with and interferes with an automatic tool changer or the like.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems found in the conventional ram horizontal machining center. An object of the present invention is to shift the installation position of the automatic tool changer to one side of the moving column. The present invention also provides a ram horizontal machining center in which the lifting motor is on the side opposite to the automatic tool changer and is directly connected to the feed screw, thereby improving the freedom of the moving column and the maintainability of the jig.

[0005]

According to a first aspect of the present invention, there is provided a horizontal ram machining center comprising: a moving column which moves on a bed in the left-right direction of a machine; and a saddle supported by the moving column and moving in a vertical direction of the machine. And a quill having a main shaft that is supported by the saddle in a horizontal position and moves in the front-rear direction of the machine. In the horizontal ram machining center, the support base plate is supported by a support upright from the bed directly above the moving column. Then, the automatic tool changer mounted on the support base plate is placed close to the top of the moving column and is set to be offset to one side of the moving column. Characterized in that it is installed on the anti-automatic tool changer side that is far from the tool changer

A ram horizontal machining center according to claim 2 is
2. The ram horizontal machining center according to claim 1, wherein the elevating motor directly connects the saddle with a feed screw that moves up and down.

[0007]

According to the first aspect of the present invention, the installation position of the automatic tool changer is on the support base plate which is offset to one side of the moving column, and the main shaft elevating motor is opposite to the automatic tool changer side. The tool changer is offset to one side of the moving column, and an open space is formed directly above a jig or the like. Thereby, the degree of freedom of the moving column and the maintainability of the jig are improved. Further, the problem that the elevating motor that moves the quill having the main shaft up and down collides with and interferes with the automatic tool changer or the like is solved.

According to the second aspect of the present invention, since the lifting motor is directly connected to the feed screw for moving the saddle up and down, the structure is simplified and the feeding accuracy is high.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings. The ram horizontal machining center 100 will be described with reference to FIGS. First, the ram horizontal machining center 100 moves the bed 1 on the left and right of the machine M.
A moving column 3 that moves in the (X-axis) direction, a saddle 5 that is supported by the moving column, and moves in the vertical direction (Y-axis) of the machine, And a quill (ram) 9 having a main shaft 7 that moves to the position shown in FIG. Immediately above the moving column 3, a column 10 upright from the bed 1.
The automatic tool changer 20 mounted on the support base plate is brought close to the top 3A of the moving column, and is set to be offset to one side (the right end in FIG. 1) of the moving column. In addition, the lifting / lowering motor YM of the saddle 5 provided at the top of the moving column is moved away from the automatic tool changer 20 on the side opposite to the automatic tool changer (FIG. 1).
At the left end). The elevating motor YM is directly connected to the upper end of a feed screw 25 threaded through the nut body 22 fixed to the saddle (see FIG. 2). The support base plate 13 has a concave portion on the side of the lift motor YM so as not to interfere with the lift motor YM (see FIG. 3).

In FIG. 1 and FIG. 2, reference numeral 30 denotes an exchange arm which is in a horizontal standby state, 32 denotes a tool magazine mounted on the support base plate 13, MM denotes a magazine motor, AM denotes a drive motor of the exchange arm, and SM denotes a drive motor of the exchange arm. Main shaft drive motor, KM
Is a drive motor for moving the quill (ram) 9 in the front-rear direction of the machine. B is a front bed, G is a jig, W is a work, and E is a processing area.

[0011] The ram horizontal machining center 100 of the present invention.
Is configured as described above, and operates as follows. As shown in FIGS. 1 to 3, the installation position of the automatic tool changer 20 is set on the support base plate 13 which is shifted to one side of the moving column 3, and the lifting / lowering motor YM
Is the anti-automatic tool changer side. Thereby, the automatic tool changer 20 is shifted to one side of the moving column 3,
An open space E1 is formed directly above the jig G and the work W. Therefore, as shown in FIG. 1, the moving column 3 does not interfere with the automatic tool changer 20 even if it moves from the central processing position (A) to the right position (tool change position A1), and the left position (A2).
Does not interfere with anything when moving to.

Thus, the lifting and the hanging work of the jig G and the work W can be efficiently performed by utilizing the space E1. And the degree of freedom of the moving column 3 and the maintainability of the jig G are also improved. Further, the problem that the lifting / lowering motor YM that moves the quill 9 having the main shaft 7 up and down collides with and interferes with the automatic tool changer 20 and the like is solved. The lifting motor is directly connected to the feed screw 25 that moves the saddle up and down, so that the configuration is simple and the feeding accuracy is high.

The present invention is not limited to the above embodiment. For example, the present invention can be applied to a type of the automatic tool changer 20, a connecting means between the lifting motor YM and the feed screw 25, and a ram horizontal machining center of a type in which the moving column 3 does not move in the left-right direction of the machine.

[0014]

According to the first aspect of the present invention, the installation position of the automatic tool changer is set on the support base plate which is offset to one side of the moving column, and the lifting / lowering motor of the main shaft is set opposite to the automatic tool changer side. The automatic tool changer is offset to one side of the moving column, and an open space is formed directly above a jig or the like. Thereby, the degree of freedom of the moving column and the maintainability of the jig are improved. Further, it is possible to solve the problem that the elevating motor for moving the quill having the main shaft up and down collides with and interferes with the automatic tool changer or the like.

According to the second aspect of the present invention, since the lifting motor is directly connected to the feed screw for moving the saddle up and down, the structure is simplified and the feeding accuracy is high.
