Linking structure of tool changer

This creation relates to the structure of a tool changer, and in particular to the interlocking structure of a tool changer.

According to the general vertical integrated center processing machine, the tool changing device basically uses a tool changing mechanism to make the tool change between the turret and the machining axis, and the tool holder on the machining shaft is released by a loosening mechanism. The function is to make the clamping part loose the tool when the tool changing arm of the tool changing mechanism is moved under the tool of the machining axis, so as to facilitate the tool changing action.

Please refer to FIG. 1A and FIG. 1B , which are structural diagrams of the interlocking structure of the conventional tool change device. The first cam 21 of the tool change mechanism 20 is a compound hobbing cam provided with a groove 24 and hobbing (not shown), and is driven by a motor 28 to rotate the first cam 21, and the shaft of the motor 28 is rotated. The rotating shaft of the first cam 21 is transmitted through the bevel gear. Further, the center of the tool changing arm 22 is fixed with a rotating shaft 25, and the rotating shaft 25 is transmitted through a rocker arm 26 and the groove 24 of the first cam 21. a coupling drive, and a rotating tower 27 meshingly coupled with the hobbing teeth of the first cam 21 to drive the upper and lower shifting arms 22 by the transmission of the groove 24 and the rocker arm 26 when the first cam 21 rotates, and The rotation of the hobbing and the rotating tower 27 causes the changing arm 22 to rotate.

The second cam 70 is disposed on one side of the machining shaft (not shown) by the chain The transmission assembly formed by the strip 72 and the sprocket 71 rotates synchronously with the first cam 21 of the tool change mechanism 20, wherein the sprocket 71 is fixed on the rotating shafts of the first and second cams 21, 70, respectively, and is wound by the chain 72. The first and second cams 21 and 70 are synchronously rotated between the sprockets 71.

A set of first swing arm 91 and second cam 70 are disposed on the same side of the machining shaft, and a roller 94 is disposed at one end thereof, and the roller 94 is in contact with the second cam 70.

However, the synchronous rotation of the first and second cams 21, 70 by the chain 72 around the sprocket 71 tends to cause loss of kinetic energy transmission, and in the process of transmitting kinetic energy, the kinetic energy transmitted is close. Hundreds of kilograms of energy can easily cause deformation of the fuselage and parts.

The reason is that there are still many shortcomings in the above existing methods, which is not a good design, but needs to be improved.

The main purpose of the present invention is to provide a linkage structure of a tool change device. The interlocking structure of the tool change device is disposed between a loose blade mechanism and a tool change mechanism of a processing machine, and the linkage structure includes a cam, a first swing arm, and a second Swing arm, first pressure block, second pressure block and loose seat. The camshaft is coupled to the tool change mechanism and has a recess in the surface. The first end of the first swing arm contacts the cam, and the second end shaft is connected to a connecting rod of one of the bases of the tool change mechanism. The first pressure block is axially coupled to the first swing arm by a connecting rod that passes through the base. The second pressing block is coupled to the loosening mechanism, and the first end thereof is in contact with the first pressing block. The second swing arm is coupled to the loosening mechanism, and the first end thereof is in contact with the second pressing block. The loose seat contacts the second end of the second swing arm, wherein the cam is driven by a motor to interlock the first swing arm, the first press block, the second press block, the second swing arm, and the loose seat.

Therefore, the interlocking structure of the creation tool changing device is reduced by Knowing the structure of the transmission component formed by the chain and the sprocket, the transmission kinetic energy loss and the efficiency of the component are reduced. In addition, the integrally formed tool changing mechanism enables the interlocking structure of the shaft to be connected to the tool changing mechanism to absorb vibration, increase strength and reduce deformation when transmitting kinetic energy, thereby further reducing the cost and improving the processing accuracy.
