Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is described in detail.
A kind of horizontal hydraulic broaching machine, as it is shown in figure 1, include lathe 1, lathe 1 is provided with broaching plate 2 and broaching tool 3.Offer on broaching plate 2 and be available for the broaching hole 4 that broaching tool 3 passes through.During broaching work, broaching tool 3 is arranged through broaching hole 4.Broaching being arranged over and cool down the cooling water pipeline 5 that water generating device connect of plate 2, cooling water passes through cooling water pipeline 5 and is positioned and is sprayed on broaching tool 3, to reduce the fricative heat between broaching tool 3 and workpiece.
As it is shown in figure 1, the both sides of lathe 1 are equipped with guide post 7, two guide posts 7 each along the axially arranged of broaching hole 4 and its be symmetrical arranged along the center of circle in broaching hole 4.The two ends of broaching plate 2 are fixed with two guide posts 7 respectively.As shown in Figure 2, offer sliding tray 14 on each guide post 7 near broaching plate 2(as shown in Figure 1) on the interior aspect face of one end, and the roughness of the inwall of sliding tray 14 is gradually increased to the direction of the one end away from broaching plate 2 along near one end of broaching plate 2.
Shown in 1 and Fig. 2, between two sliding trays 14, be provided with buffer stopper 12, the two ends of buffer stopper 12 be equipped with for stretch into sliding tray 14 and in sliding tray 14 slide block 13 of movement.Offering cushion hole 15 on buffer stopper 12, the axial line in the axial line of cushion hole 15 and broaching hole 4 is on the same line.The diameter of cushion hole 15 is gradually increased, as trapezoidal along near the side of broaching plate 2 away from the direction of the side of broaching plate 2.
Shown in Fig. 5 and Fig. 6, the inwall of cushion hole 15 is provided with a circle ball 16, ball 16 is rotatably connected to connect ring 17.Connect and be connected with brush 18 on ring 17.As it is shown on figure 3, the side near broaching plate 2 is provided with Magnet 19 on buffer stopper 12, Magnet 19 is arranged along the outer rim of cushion hole 15.As in figure 2 it is shown, the side away from broaching plate 2 is provided with shielding plate 20 on buffer stopper 12, shielding plate 20 is arranged along the outer rim of cushion hole 15.On buffer stopper 12, the side away from broaching plate 2 is additionally provided with two elastic components 21, and the two elastic component 21 is symmetrical arranged along cushion hole 15.It is respectively and fixedly provided with release link 22 on each elastic component 21.
As it is shown in figure 1, lathe 1 is provided with promotion plate 8, plate 8 is promoted to be located between two guide posts 7 and promote the two ends of plate 8 to be all slidably connected with guide post 7.Plate 8, broaching plate 2 and two guide posts 7 are promoted to surround a shifting chute 11.The side promoting plate 8 is connected with fixing seat 9, and its opposite side is connected with the piston rod 6 being controlled motion by pushing means such as oil cylinder.Fixing seat 9 is provided with and broaches hole 4, cushion hole 15 fixing hole 10(on the same line as shown in Figure 3), the size of fixing hole 10 be available for broaching tool 3 stretch into and with its clamping.
During work, broaching tool 3 is stretched into successively broaching hole 4, cushion hole 15 and fixing hole 10；After broaching tool 3 and fixing seat 9 being connected and fixed, workpiece is set on broaching tool 3 one end away from fixing seat 9；Start oil cylinder and cooling water generating device, piston rod 6 drives broaching tool 3 to do the motion away from broaching plate 2, workpiece and the external screw thread friction broaching on broaching tool 3, produce bigger heat, cooling water in cooling water pipeline 5 is sprayed on workpiece and broaching tool 3 lower the temperature, and the metal fillings that most broaching produces can be rinsed out by cooling water simultaneously；Broaching tool 3 is under the pulling of piston rod 6 in entrance cushion hole 15, on broaching tool 3, the metal fillings of residual can be washed away further by Magnet 19 or the brush 18 rotated, and owing to the probability in the metal fillings entrance fixing hole 10 of these residuals of existence of shielding plate 20 is low, fixing between fixing hole 10 and broaching tool 3 can be improved；Meanwhile, under the drive of broaching tool 3, buffer stopper 12 moves along sliding tray 14；When the end of broaching tool 3 is close to when being completely disposed in broaching hole 4, the active force being subject between end and the front end of broaching tool 3 of broaching tool 3 has certain difference, and this gap is weakened under broaching tool 3 directly acts on cushion hole 15, and owing to the aperture of cushion hole 15 increases successively, broaching tool 3 remains to keep surely entering after completely disengaging from cushion hole 15, reduces broaching tool vibration further；
Broaching end-of-job also removes broaching tool 3, starts oil cylinder and makes piston rod 6 do the motion near broaching plate 2, after moving to certain distance, promotes plate 8 to contact with release link 22 and promote buffer stopper 12 to move along sliding tray 14 and makes buffer stopper 12 reset.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
