Abstract
The invention relates to a grinding device for a gate of a high temperature alloy casting and belongs to the technical field of the grinding device. The grinding device comprises a fixture for clamping the casting; the lower part of the fixture is connected onto a first base in a sliding mode; one end of the fixture faces sand leather; the sand leather is connected on a rotating shaft; the rotating shaft is driven by a driving mechanism to rotate; a first cylinder is fixed at one end of the first base; and the fixture is pushed by the first cylinder to move toward the sand leather. When the grinding device is in use, the casting is fixed in the fixture, the fixture is pushed by the first cylinder to move toward the sand leather, the casting on the fixture is pushed to the sand leather and the redundant gate on the fixture is ground off by the sand leather. The sand leather is utilized to replace a cutter to remove the redundant gate, and therefore, on one hand, the cost of the sand leather is much lower than that of the cutter, so that the processing cost can be greatly reduced, and on the other hand, due to the adoption of the grinding processing mode, the sand leather and the high temperature alloy casting are difficult to adhere, so that the smooth finish of the processed surface is also greatly improved.
Description
Technical field
The present invention relates to a kind of grinding attachment, especially relate to a kind of high-temperature alloy casting cast gate grinding apparatus and method for grinding.
Background technology
Foundry goods is after cast molding, the unnecessary cast gate of inevitable generation, in the past for these cast gates, be all to remove by getting on the bus to prune at lathe, but for some high-temperature alloy castings, viscosity is high, easily be bonded on cutter, cutting ability extreme difference, makes the life-span of cutter very short, and this has just increased production cost.In addition, because the viscosity of alloy-steel casting is high, cutter due to adhesion, is also difficult to form bright and clean tangent plane in cutting, is therefore necessary to be changed.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of high-temperature alloy casting cast gate grinding apparatus and method for grinding are provided, can remove fast cast gate, greatly reduce costs, the fineness of finished surface also improves greatly simultaneously.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of high-temperature alloy casting cast gate grinding apparatus, comprise the fixture for clamping foundry goods, the slid underneath of described fixture is connected on the first pedestal, one end of described fixture is facing to rubber, and described rubber is connected in rotating shaft, and described rotating shaft is driven and rotated by driving mechanism, on one end of described the first pedestal, be fixed with the first cylinder, described the first cylinder promotes described fixture and moves to rubber.When use, foundry goods is fixed in fixture, utilizes the first cylinder to promote fixture and moves to rubber, and on fixture, foundry goods is pushed rubber to, and rubber grinds away the unnecessary cast gate on fixture.Utilize rubber to replace cutter to remove unnecessary cast gate, the cost of rubber is more much lower than cutter on the one hand, and this processing mode of grinding, is not easy to bond between rubber and high-temperature alloy casting on the other hand, and therefore the fineness of finished surface also improves greatly.
In technique scheme, preferred, described fixture comprises an accommodation section, and one end of described accommodation section is provided with second cylinder, and the piston rod of described the second cylinder stretches in described accommodation section, is fixed with a baffle plate on the piston rod of described the second cylinder.Foundry goods is placed in accommodation section, need to add man-hour, and the piston rod of the second cylinder stretches out in accommodation section, and baffle plate withstands one end of foundry goods, and the other end of foundry goods withstands on accommodation section, realizes the clamping of foundry goods.After processing, piston rod exits in accommodation section, and baffle plate unclamps one end of foundry goods, and foundry goods just gets loose from accommodation section like this.
In technique scheme, preferred, described fixture also comprises a base plate, and the bottom of described accommodation section is fixed with a swivel nut, on described base plate, is provided with screw rod, and described screw rod and described swivel nut are rotatably connected.After rubber uses one end time, wear and tear gradually in top layer, this just causes the relative distance between foundry goods and rubber top layer to become gradually far away, pass through rotating screw bolt, can regulate the position of accommodation section, make the foundry goods in accommodation section remain consistent with the relative position on rubber top layer, like this as long as the final position that the each piston rod of the first cylinder arrives can be consistent, just can ensure the position consistency that cast gate grinding arrives, greatly easy to the control of the first cylinder.
In last technical scheme, preferred, the bottom of described base plate is provided with two the first projections, on described the first pedestal, is provided with the first guide rod, and described the first guide rod is through described the first projection.The cooperation of the first guide rod and the first projection is for limiting the direction of motion of fixture on the first pedestal.
In technique scheme, preferred, also comprise second pedestal, described the first pedestal is slidably connected on the second pedestal, is provided with the 3rd cylinder on described the second pedestal, and described the 3rd cylinder promotes the transverse shifting of described the first pedestal along described rubber.When the 3rd cylinder promotes the first pedestal and moves left and right, also drive foundry goods to move left and right, ensured that foundry goods can all contact with positions all on rubber, rubber can be fully utilized simultaneously.
In last technical scheme, preferred, the bottom of described the first pedestal is provided with two the second projections, on described the second pedestal, is provided with the second guide rod, and described the second guide rod is through described the second projection.The second projection coordinates for limiting the direction of motion of the first pedestal on the second pedestal with the second guide rod.
A cast gate method for grinding for high-temperature alloy casting, comprises the steps: 1) foundry goods is placed in described accommodation section, start described the second cylinder, the piston rod of described the second cylinder promotes described baffle plate and holds out against foundry goods; 2) start described drive unit, described drive unit drives described rotating shaft to rotate, and described rotating shaft drives described rubber to rotate; 3) piston rod on described the first cylinder stretches out, promoting described fixture moves to described rubber frontal along described the first guide rod, make the casting sprue on described fixture contact described rubber, simultaneously described the 3rd cylinder starts, and promotes the first pedestal and moves along the transverse reciprocating of described rubber; 4) distance that the piston rod of described the first cylinder stretches out reaches after setting value, the cast gate grinding of foundry goods completes, piston rod on described the first cylinder is regained, stop the running of described the 3rd cylinder simultaneously, then the piston rod on described the second cylinder is regained, and foundry goods can take out in described accommodation section.
The invention has the beneficial effects as follows: utilize rubber to replace cutter to remove unnecessary cast gate, the cost of rubber is more much lower than cutter on the one hand, can greatly reduce costs.This processing mode of grinding, is not easy to bond between rubber and high-temperature alloy casting on the other hand, and therefore the fineness on surface also improves greatly.
