Description
The present invention relates to a slide type tool changer, and more particularly, it relates to a slide type tool changer in which a correct tool port is selected in a process of exchanging a tool provided in a tool port, and an inclination angle of the cam guide is reduced, And a shock absorber is provided on the arm support so as to minimize an impact generated upon return.
In general, a machining center consists of an automatic tool changer (ATC) and an NC device that automatically changes the body and a number of tools to match cutting conditions. Therefore, it is mainly used for automation of machining process of small quantity of various kinds of parts.
The machining centers are known in various forms for continuously machining the workpiece while exchanging the tool housed in the tool magazine according to the machining program.
As an example, the tool magazine is installed at the same height as the workbench at one end spaced apart from the workbench. When the tool is exchanged, the spindle head is moved to one end of the tool magazine.
These tool magazines contain various tools such as tabs, drills and reamers of different dimensions and shapes. When the tool change timing is reached, the tool is first returned to the empty position of the tool magazine, indexed to be replaced, The tool was automatically replaced by replacing the tool.
After the tool is replaced, the spindle head is transferred to the work table to perform the work. This requires a great deal of time from the current process to the next process, There is a problem that the efficiency of the coating decreases.
In order to solve the problems, an automatic tool changer of a machining center of Patent Registration No. 10-968575 (Jun. 30, 2010) has been proposed, and the proposed automatic tool changer has been proposed as an optimum work cross- The magazine which is open at both sides at the same time is moved in the horizontal direction so that the tool can be quickly replaced and it is possible to install the automatic apparatus and to prevent the workpiece from being interfered when the workpiece is put on or taken out of the jig, There is another problem that an interference phenomenon with a cam driven in the process occurs and it is partially broken.
This problem has also been caused by the conventional sunflower type automatic tool changer, and there is another problem that it is difficult to select an accurate tool port because of the cause of the impact upon return.
In the present invention, an accurate tool port of the arm is selected by the arm cylinder and the stop piece in the process of exchanging the tool provided in the tool port, and a shock absorber is provided on the arm support so that the impact generated upon return can be minimized In addition, the inclination angle of the cam guide is reduced so that the load can be reduced while reducing the travel distance.
The present invention relates to a tool support apparatus comprising a tool support provided on an upper portion of a main shaft, an arm support provided on a front surface of the tool support, an arm coupled to the arm support by a hinge at an upper end thereof, A cam provided perpendicularly to the tool support, a cam provided to rotate the arm by the cam guide, and a cam fixed to an upper end of the arm, the stop being supported by a stop piece extended to a lower portion of the tool support Wherein a shock absorber for preventing a return shock of the arm is coupled to the arm support, the inclined guide member is hinged to a lower end of the cam guide and is engaged with a spring, The lower ends of the arms are coupled to both sides of the arm, and a plurality of the tool ports are coupled to the rear surface.
According to another aspect of the present invention, there is provided a tool support apparatus including a tool support provided on a top of a main shaft, an arm support provided on a front surface of the tool support, an arm coupled to the arm support by a hinge at an upper end, A cam provided perpendicularly to the tool support, a cam provided to rotate the arm by the cam guide, and a stopper fixed to an upper end of the arm and extending to a lower portion of the tool support, A shock absorber for preventing a return shock of the arm is coupled to the arm support, a slant guide member is hinged to a lower end of the cam guide, and the hanger is engaged with the shock absorber, A cam guide panel is provided with a first inclined portion at a lower front of the cam, a guide portion facing the upper portion of the back surface of the first inclined portion, The features formed in the first front lower edge of the second inclined portion and the inclined portion parallel to the cam guide panel.
Further, the hinge portion is supported so that both ends of the hinge shaft are rotated by the rotation supporting portions, and the upper end portions of the arms are coupled to both side ends of the hinge shaft.

Further, the cam is fixed to one side end of the cam guide by the side of the arm, and the cam roller is coupled to the other end of the cam guide.
The present invention is characterized in that, in a state in which an actuator having a tool port is coupled to an arm support, a cam is pushed by a cam guide to pivot the arm so that the arm is rotated by the arm cylinder and the stop piece, It is possible to obtain an effect that the accurate tool port of the tool is selected.
In addition, by reducing the inclination angle of the cam guide, it is possible to reduce the load while reducing the transfer distance.
In addition, by providing the shock absorber on the arm support, it is possible to minimize the impact generated upon return.
This makes it possible to improve the precision while reducing the weight as a whole, and to prolong the life span.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view of a slide-type tool changer according to the present invention, FIG. 2 is a side view of a slide-type tool changer according to the present invention, Fig.
The machining center in which the slide type tool changer is used is basically provided with a drive motor, a main shaft, a bed, a saddle, a table, a column, an automatic tool changer (ATC), a strong control panel, The necessary tools are automatically arranged in correspondence with the new machining surface in order to perform various machining operations such as cutting (cutting), drilling, punching and polishing, all in one machine.
The automatic tool changer automatically exchanges the tool that is fixed on the main spindle with the tool to be used for the next machining. There are different types according to the size of the machine (turret type, storage type, etc.) There are dozens from dogs.
The turret type is a method in which several tools are installed directly on the tool rest, the tool rest is rotated, and the tool is moved linearly to move the necessary tools to the working position. The exchange time is short, but sufficient intervals And the number of stored tools is limited.
On the other hand, the magazine type has a tool storage magazine that stores several tools at a position away from the main axis, moves the tool built in the magazine to the replacement position, Exchange. This method is widely used in machining centers and machine tools that require many tools to machine various kinds of parts. The tool call method is a random method in which arbitrary tools can be exchanged by calling with a number, and a sequential type in which the main spindle is mounted in the order of arrangement.
The slide type tool changer according to the present invention improves accuracy by selecting an accurate tool port in the process of exchanging a tool provided in the tool port, while reducing the transfer distance of the tool port, The
The main spindle S includes a spindle motor and a pulley connected to the spindle S by a V belt so that the main spindle S can be rotated The hole of the main shaft is tapered so that the center of the spindle and the center of the tool are exactly aligned when the tool is clamped.
