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 is used as a supporting component of the device. A rotating table 2 is installed at the center of the top of the base 1, and the rotating table 2 provides steering power for a workbench 6 described below. According to the actual distribution of the piston riser (the longitudinal riser of the piston blank is perpendicular to the transverse riser), the workbench 6 needs to be rotated 90 degrees to complete sawing of the transverse riser after sawing of the longitudinal riser, and the rotating table needs to be rotated 90 degrees each time, so the rotating table 2 selects a four-station divider in the embodiment. The top of the rotating table 2 is vertically provided with a plurality of guide posts 3, and preferably, in the embodiment, 4 guide posts 3 are uniformly arranged on the top of the rotating table 2 in a circumference manner. The top bolts of the guide posts 3 are fixedly provided with an installation table 4, the top bolts of the installation table 4 are fixedly provided with hydraulic cylinders 5, and piston rods of the hydraulic cylinders 5 penetrate through the installation table 4 and are exposed between the guide posts 3. The guide post 3 is slidably provided with a workbench 6 through a linear bearing, and a piston rod of the hydraulic oil cylinder 5 penetrates through the mounting table 4 to be fixedly connected with the middle part of the workbench 6. The workbench 6 can be driven to lift along the guide post 3 by the extension and retraction of the hydraulic oil cylinder 5. In particular, the table 6 is used for placing a piston blank. Specifically, in order to further increase the riser sawing efficiency of the piston blank, the workbench 6 is made into a square plate shape, and the four sides of the workbench 6 are all bolted with the V-shaped groove fixing blocks 11, wherein the top of the V-shaped groove fixing blocks 11 is provided with V-shaped grooves. After the workbench 6 rotates 90 degrees, the V-shaped groove fixing blocks 11 on four sides are positioned at the positions where the last V-shaped groove fixing block is positioned. More specifically, the "V" groove fixing block 11 at each side has two "V" grooves at the top thereof, and two pistons connected together by a riser can be placed therein to fix them. The base is quadrilateral, a bolt fixing frame body 7 is arranged at one side of the base 1, a mounting column 8 corresponding to one end of the frame body 7 is mounted on the top bolt of the base 1, and the mounting column 8 is located at the top angle of one side of the base opposite to the frame body 7. A longitudinal sawing device 9 is arranged between the frame body 7 and the mounting column 8, and a transverse sawing device 10 is arranged in the middle of the frame body 7. The longitudinal sawing device 9 is used for cutting off a longitudinal riser connected between the two piston blanks and a longitudinal riser at the other side of the piston blanks, and the transverse sawing device 10 is used for cutting off a transverse riser at the end faces of the two pistons. The actions of the rotating table 2 and the hydraulic cylinder 5 are controlled by control buttons, so that automatic sawing operation of the piston casting riser is realized, and manual holding of a piston or sawing equipment is not needed, thereby completing the sawing operation of the piston riser rapidly, 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 center 94, the first spindle head 92 is bolted to one end of the frame 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 a 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. The mounting shaft 93 is connected with two pairs of first saw blades 95 in an upper key manner, and the first saw blades 95 are perpendicular to the side edges of the adjacent workbench 6. The distance between each pair of the first saw blades 95 is the diameter of the piston blank, and each pair of the first saw blades 95 is responsible for cutting off the longitudinal riser on two sides of one piston blank. The device can play a role in stabilizing the high-speed rotation of the installation shaft by propping the end part of the installation shaft 93 through the center, and prevent the movement of the installation shaft from influencing the cutting effect of the first saw blade 95. Specifically, the transverse sawing device 10 includes a second motor 101 and a second spindle head 102, the second spindle head 102 is bolted to the middle of the frame 7, the second motor 101 is bolted to the top of the second spindle head 102, and the second motor 101 drives the rotating shaft of the second spindle head 102 to rotate through belt transmission. A second saw blade 103 is installed on the rotating shaft of the second spindle head 102, and the second saw blade 103 is parallel to the side edge of the adjacent workbench 6. The central shaft of the second saw blade 103 is positioned at the middle position of the two slots, so that the second saw blade 103 can cover the range of two piston blanks, and the cutting of the transverse riser of the two piston end faces is completed.
Guide grooves are arranged below the longitudinal sawing device 9 and the transverse sawing device 10, and the guide grooves are fixedly connected with the base 1. The guide chute guides the riser residues cut by sawing into a collecting box at the side edge of the base 1.
When the device is used, a piston blank is placed in a V-shaped groove at the top of the V-shaped groove fixing block, and then the hydraulic cylinder is controlled to drive the workbench to ascend, so that the first saw blade and the second saw blade can contact with a longitudinal riser and a transverse riser of a piston, and therefore the longitudinal riser of the piston at the position of the first V-shaped groove fixing block is cut off, and the transverse riser at the position of the second V-shaped groove fixing block is cut off. Then controlling the hydraulic cylinder to drive the workbench to descend, simultaneously controlling the workbench to rotate 90 degrees by the four-station divider, and then continuously controlling the hydraulic cylinder to drive the workbench to ascend to finish the longitudinal riser cutting at the position of the second V-shaped groove fixing block and the transverse riser cutting at the position of the third V-shaped groove fixing block; and repeating the operation circularly, thereby completing the sawing operation of the transverse riser and the longitudinal riser of the piston.
After the transverse riser and the longitudinal riser of the piston blank are sawed, the workbench is put down by utilizing the hydraulic oil cylinder, the sawed piston is taken down, and then a new piston blank is put on.
