Background
The casting is formed by smelting, so that burrs and particles often appear on the surface of the casting, the appearance is not attractive, and the service performance of the casting is also influenced. The traditional mode is to adopt the handheld work piece of operator directly to polish, can eliminate surperficial burr, granule scheduling problem, and this intensity of labour is big not only, and the manual work is polished the surface of the foundry goods that can not be even moreover, and can only be to some small-size parts. For some parts with large volume and complex structure, polishing machines such as a grinding machine are needed for polishing, and the parts are inconvenient to position and clamp due to irregular shapes, and efficient polishing cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
In order to the problem, the utility model provides a foundry goods positioning fixture that polishes uses plane, locating pin location, and the hydro-cylinder compresses tightly, and simple effectual assurance foundry goods location on anchor clamps is tight, and the clamping is simplified when making anchor clamps polish, improves production efficiency.
The utility model discloses a foundry goods positioning fixture that polishes, its characterized in that: the positioning device comprises a bottom plate fixedly connected with a rack, wherein a plurality of positioning pin supporting seats which are detachably connected are arranged on the bottom plate, positioning pins which are vertically and upwards fixedly arranged are arranged on the plurality of positioning pin supporting seats, and the distances between the positioning pins and the center of the bottom plate are different; the center of the bottom plate is provided with a detachably connected oil cylinder supporting seat, an oil cylinder is arranged on the oil cylinder supporting seat, an oil cylinder piston rod is vertically and upwards arranged, a tension rod is arranged on the oil cylinder piston rod, and a tension pressing block is sleeved on the tension rod.
Furthermore, a threaded hole mounted with the frame is formed in the bottom plate.
Further, the number of the positioning pins is three.
Furthermore, the tensioning pressing block is a circular plate, a U-shaped opening for accommodating the tensioning rod is formed in the circular plate, and the U-shaped opening passes through the center of the tensioning pressing block.
Furthermore, the top end of the tension rod is provided with a pressing part with a diameter larger than the U-shaped opening on the tension pressing block.
The utility model has the advantages that: the casting compresses tightly between bottom plate and taut briquetting, and the locating pin is positioned in the round hole of casting terminal surface, and anchor clamps link firmly on the workstation of equipment of polishing together with the casting is whole, once fix a position the clamping, can polish casting external surface, has simplified the casting clamping degree of difficulty, has alleviateed workman's intensity of labour, increases substantially work efficiency and polishing precision simultaneously.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
A foundry goods location anchor clamps that polishes as shown in fig. 1-2 characterized by: the positioning device comprises a bottom plate 1 fixedly connected with a rack, wherein a plurality of positioning pin supporting seats 2 which are detachably connected are arranged on the bottom plate 1, positioning pins 3 which are vertically and upwards fixedly arranged are arranged on the plurality of positioning pin supporting seats 2, and the distances between the positioning pins 3 and the center of the bottom plate 1 are different; the center of the bottom plate 1 is provided with a detachably connected oil cylinder supporting seat 4, the oil cylinder supporting seat 4 is provided with an oil cylinder 5, a piston rod of the oil cylinder 5 is vertically and upwards arranged, a tension rod 6 is arranged on the piston rod, and a tension pressing block 7 is sleeved on the tension rod 6.
Furthermore, a threaded hole mounted with the frame is formed in the bottom plate 1.
Further, the number of the positioning pins 3 is three.
Further, the tightening pressing block 7 is a circular plate, and a U-shaped opening for accommodating the tightening rod 6 is formed in the circular plate, and the U-shaped opening passes through the center of the tightening pressing block 7.
Furthermore, the top end of the tension rod 6 is provided with a pressing part with a diameter larger than the U-shaped opening on the tension pressing block 7.
The utility model discloses during the use, according to the structure of the foundry goods of treating polishing, the position of round hole on its terminal surface, the position of adjustment locating pin 3 makes the round hole cooperation of two locating pins 3 and foundry goods terminal surfaces, and 1 is gone up to anchor clamps bottom surface has 3 locating pins 3 altogether, establishes respectively on the circumference of difference, satisfies the location requirement of a plurality of not unidimensional foundry goods, improves the application scope of anchor clamps. The tensioning pressing block 7 is pressed on the upper end face of the casting, the casting is pressed by the tensioning rod 6 under the action of the oil cylinder 5, the pressing structure is simple, when the casting is dismounted, the piston rod of the oil cylinder extends out, the tensioning rod is loosened, the tensioning pressing block is taken down from the U-shaped opening, the casting can be taken down from the clamp, and parts are replaced. The clamp adopts one-surface two-pin positioning, so that the position of the casting on the clamp is fixed, and the phenomena of rotation, displacement and the like in the polishing process are avoided, the polishing precision is influenced, and even safety accidents are caused.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
