Detailed Description
The invention is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.
As shown in fig. 1-5, the special piston saw casting head machine comprises a base 1, wherein the base 1 is welded with a plate through a section bar and serves as a supporting component of the special piston saw casting head machine. The base 1 is provided with a rotating platform 2 at the top center position, and the rotating platform 2 provides steering power for a workbench 6 described below. According to the actual distribution of the piston risers (the longitudinal risers of the piston blank are perpendicular to the transverse risers), after the longitudinal risers are sawn, the workbench 6 needs to rotate 90 degrees to complete the sawing of the transverse risers, and the workbench needs to rotate 90 degrees each time, so that the workbench 2 in the embodiment selects a four-station divider. A plurality of guide posts 3 are vertically installed at the top of the rotating table 2, and preferably, 4 guide posts 3 are evenly installed on the top of the rotating table 2 in a circumferential manner in the embodiment. The top of the guide column 3 is fixed with a mounting table 4 through bolts, the top of the mounting table 4 is fixed with a hydraulic oil cylinder 5 through bolts, and a piston rod of the hydraulic oil cylinder 5 penetrates through the mounting table 4 and is exposed between the guide columns 3. A workbench 6 is slidably mounted on the guide column 3 through a linear bearing, and a piston rod of the hydraulic oil cylinder 5 penetrates through the mounting platform 4 to be fixedly connected with the middle of the workbench 6. The workbench 6 can be driven to ascend and descend along the guide post 3 by the expansion of the hydraulic oil cylinder 5. Specifically, the workbench 6 is used for placing piston blanks. Specifically, in order to further increase the dead head sawing efficiency of the piston blank, the workbench 6 is made into a square plate shape, the V-shaped groove fixing blocks 11 are fixed on four sides of the workbench 6 through bolts, and the V-shaped groove is formed in the top of each V-shaped groove fixing block 11. After the workbench 6 rotates 90 degrees, the V-groove fixing blocks 11 on the four sides are located at the positions where the last V-groove fixing block is located. More specifically, the "V" groove fixing block 11 at each side has two "V" groove positions at the top thereof, in which two pistons connected together through risers can be placed to be fixed. The base is the quadrangle, 1 side department bolt fastening support body 7 of base, 1 top bolt installation of base and the corresponding erection column 8 of 7 one ends of support body, erection column 8 are located the one side apex angle department wherein of the base and the relative one side of support body 7. A longitudinal sawing device 9 is installed between the frame body 7 and the mounting column 8, and a transverse sawing device 10 is installed in the middle of the frame body 7. The longitudinal sawing device 9 is used for cutting off the longitudinal risers connected between the two piston blanks and the longitudinal risers on the other side of the piston blanks, and the transverse sawing device 10 is used for cutting off the transverse risers on the end faces of the two pistons. The actions of the rotating table 2 and the hydraulic oil cylinder 5 are controlled by control buttons, automatic saw cutting operation of the piston casting riser is achieved, manual piston holding or saw cutting equipment is not needed, and therefore saw cutting operation of the piston riser can be completed quickly, efficiently and safely.
Specifically, the longitudinal sawing device 9 includes a first motor 91, a first spindle head 92, a mounting shaft 93, and a tip 94, the first spindle head 92 is bolted to one end of the frame body 7 corresponding to the mounting post 8, the first motor 91 is bolted to the top of the first spindle head 92, and the first motor 91 and the rotating shaft of the first spindle head 92 are driven by a belt. The rotation shaft of the first spindle head 92 is driven to rotate by the first motor 91. The rotating shaft of the first spindle head 92 is coaxially fixed with the mounting shaft 93, the center 94 is fixed on the mounting column 8 through bolts, and the center 94 is matched with the other end of the mounting shaft 93. Two pairs of first saw blades 95 are keyed on the mounting shaft 93, and the first saw blades 95 are perpendicular to the side edges of the adjacent working tables 6. The distance between each pair of first saw blades 95 is the diameter of the piston blank, and each pair of first saw blades 95 is responsible for cutting off the longitudinal risers on both sides of one piston blank. This device withstands installation axle 93 tip through top, can play stable effect to the high-speed rotation of installation axle, prevents that installation axle drunkenness from influencing the cutting effect of first saw bit 95.
