Description
Technical Field
The utility model belongs to the technical field of aluminum casting machine tooling, a disk aluminum casting top surface annular processing centre gripping frock is related to.
Background
The top surface of the disc-shaped aluminum casting shown in fig. 1 is provided with an annular groove a matched with other accessories, the accuracy requirement of the annular groove is high, and the annular groove a needs to be finely milled in a machining mode after die casting. The disc-shaped aluminum casting needs to be clamped on a machine tool in an auxiliary mode through a clamping tool. The existing clamping tool is shown in fig. 2, and the positioning of a casting in the tool is realized by utilizing a positioning hole B at the bottom of the aluminum casting, and the clamping of the casting in the tool is realized by utilizing a pneumatic pressing plate C. And after the aluminum casting is processed, loosening the nut of the pneumatic plate C, and removing the plate to take out the aluminum casting. However, the distance between the disc-shaped aluminum casting and the jig plate is small, and the disc-shaped aluminum casting can be taken out only by an auxiliary tool, which is very troublesome.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the existing clamping tool is improved so as to achieve the purpose of taking out the aluminum casting without an auxiliary tool.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
the disc-shaped aluminum casting top surface ring groove machining clamping tool comprises a jig plate, a positioning needle and a pneumatic pressing plate, wherein the positioning needle is fixed in the jig plate, the pneumatic pressing plate comprises an air cylinder, a connecting rod and a plate, the air cylinder is fixed at the bottom of the jig plate, one end of the connecting rod is fixedly connected with a telescopic rod of the air cylinder, the other end of the connecting rod is provided with a threaded portion, the bottom of the plate is provided with a U-shaped clamping groove, the threaded portion is located in the U-shaped clamping groove, and a nut movably connected with the plate is arranged on the threaded portion; the jig plate is provided with a movable insert, and the connecting rod penetrates through the movable insert and is fixedly connected with the movable insert.
The location of foundry goods is realized to the pilot pin, and the centre gripping of foundry goods is realized to outside pneumatic clamp plate, and after aluminium casting processing was accomplished, the cylinder was inserted the movable and is pushed up with the aluminium casting, unscrews the nut, unloads the plate and can take out the aluminium casting.
Compared with the prior art, the beneficial effects of the utility model are that: utilize the activity to insert upwards to push away from the tool board with the aluminium casting, make to form great clearance between aluminium casting and the tool board, the aluminium casting also breaks away from with the pilot pin, so need not to take out the aluminium casting with the help of appurtenance, labour saving and time saving.

fig. 4 is a sectional view of the clamping tool disclosed in the embodiment.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
Please refer to fig. 3, which illustrates a processing clamping fixture, including a fixture plate 10, a positioning pin 20 and a pneumatic pressing plate, wherein the positioning pin is fixed in the fixture plate, the pneumatic pressing plate includes a cylinder 31, a connecting rod 32 and a plate 33, the cylinder is fixed at the bottom of the fixture plate, one end of the connecting rod is fixedly connected with a telescopic rod of the cylinder, the other end of the connecting rod is provided with a threaded portion, the bottom of the plate is provided with a U-shaped slot 331, the threaded portion is located in the U-shaped slot, and the threaded portion is provided with a nut 34 movably connected; the jig plate is provided with a movable insert 40, and the connecting rod penetrates through the movable insert and is fixedly connected with the movable insert. The location of foundry goods is realized to the pilot pin, and the centre gripping of foundry goods is realized to outside pneumatic clamp plate, and after aluminium foundry goods processing was accomplished, the cylinder was inserted with the activity and the jacking of aluminium foundry goods, made form great clearance between aluminium foundry goods and the tool board, and the aluminium foundry goods also breaks away from with the pilot pin, unscrews nut 34, unloads plate 33 and can bare-handed take out the aluminium foundry goods.
After the telescopic rod of the cylinder retracts, the movable insert is completely positioned in the jig plate, only the part of the top of the movable insert, which is in contact with the aluminum casting, is positioned above the jig plate, and a abdicating groove corresponding to the aluminum casting is arranged in the movable insert.
The jig plate is provided with a bore groove 11 for receiving the movable insert, the bore groove is provided with an annular step 12, and the annular step is provided with a guide rod 50 inserted into the movable insert. After the movable insert is lifted, the movable insert is not separated from the guide rod, if the thickness of the jig plate is not enough, a support block 60 can be fixedly arranged at the bottom of the jig plate, and the guide rod is fixed in the support block (see fig. 4).
