In order to more clearly illustrate the creation, the preferred embodiment is DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIG. 2 to FIG. 4, the five-axis processing machine 100 is a preferred embodiment. The five-axis machining machine 100 includes a base 10, a sliding platform 20, a rocking seat 30, a rotating base 40, a saddle 50, a spindle head 60, and a support structure 70.

The base 10 includes a first platform 12 and a second platform 14. In this embodiment, the height of the table surface of the first platform 12 is lower than the height of the table surface of the second platform 14. And the first platform 12 is provided with a first linear slide rail 12a extending horizontally, and the second platform 14 is provided with a second linear slide rail 14a extending horizontally, wherein the first linear slide rail 12a and the first The two linear slides 14a are vertically oriented but do not intersect each other.

Referring to FIG. 2 and FIG. 3, the sliding platform 20 moves forward and backward along the first linear slide rail 12a. The rocking seat 30 is disposed on the sliding platform 20 and swings leftward and rightward with reference to a first axis V1 of the first linear slide rail 12a, and the swing amplitude is set to not exceed 120 degrees. The rotating base 40 is disposed on the rocking seat 30 and rotates about a second axis V2 perpendicular to the first axis V1, and the rotating base 40 provides a fixed object to be processed, in other words, the object to be processed is not only It can be controlled to rotate or swing.

The saddle 50 is coupled to the second platform 14 and moves left and right along the second linear slide rail 14a. In the embodiment, the saddle 50 is a trapezoidal shape with an upper width and a lower width, that is, the saddle. The volume of the upper half of the seat 50 is smaller than the volume of the lower half such that the center of gravity of the saddle 50 as a whole ensures that it is within the vertical projection range of the table top of the second platform 14. In other words, the second platform 14 can bear the total weight of the saddle 50 on average, avoiding the weight of the saddle 50 from causing stress concentration on any part of the base 10 to cause damage. In addition, the saddle 50 has an end surface 52 on which a third linear slide 52a is disposed, wherein the end surface 52 is perpendicular to the horizontal direction.

The spindle head 60 is coupled to the saddle 50, and the spindle head 60 provides a tool (not shown) that is coupled to the tool. The third linear slide 52a provided along the saddle 50 is moved up and down by a lead screw 54 disposed in the saddle 50, and is relatively loaded on the rotary base 40. Approach or leave for processing.

Referring to FIG. 4 again, the support structure 70 includes at least one bracket 72 and at least one pneumatic cylinder 74. In this embodiment, two brackets 72 and two pneumatic cylinders 74 are taken as an example, and each pneumatic cylinder 74 is combined with a bottom end. On each of the brackets 72, a piston rod 76 extending from the top end is respectively locked to the spindle head 60, and each bracket 72 is separately locked to the periphery of the upper end surface of the saddle 50, so that the respective pneumatic cylinders 74 are provided. Located between the saddle 50 and the spindle head 60 respectively, the saddle 50 can indirectly support a portion of the weight of the spindle head 60 through the support structure 70.

In addition, when each pneumatic cylinder 74 is activated by a pneumatic source (not shown), a pneumatic pressure is generated inside each pneumatic cylinder 74 to provide a vertical upward force of the piston rod 76, and the force is equal to the force. The spindle head 60 is vertically downwardly weighted to achieve a force balance between the spindle head 60 and the force.

In combination with the components of the five-axis processing machine 100 and the connection relationship between the components, the weight of the saddle 50 vertically falls within the vertical projection range of the second platform 14, so that it can be stably slid along the second straight line. The left and right movement of the rail 14a can not only avoid the saddle of the conventional processing machine from being suspended and connected with the pedestal, and the occurrence of a slight shaking situation affects the processing precision, and can avoid the damage caused by the excessive stress concentration at the joint; In addition, the spindle head 60 is supported by the force of each pneumatic cylinder 74 to achieve a force balance, thereby effectively preventing the spindle head 60 from generating a bending moment on the saddle 50 to drive the machine to shake. In this way, the five-axis processing machine 100 of the present invention can be stably processed to achieve the purpose of improving the precision of the workpiece.

The above description is only a preferred and feasible embodiment of the present invention, and the equivalent change of the application specification and the scope of the patent application should be applied. It is included in the scope of this creation patent.
