Device and method for clamping casting

Abstract

The invention relates to a device and method for clamping a casting and belongs to the field of sand-lined metal mold casting equipment. The device for clamping the casting comprises a base, rail plates, rollers, a manipulator structure, roller shafts and two air cylinder sets in the same structure; the rail plates are mounted on the base; each air cylinder set comprises an air cylinder connectionseat, an air cylinder body, an air cylinder piston rod and an air cylinder hinge head, the air cylinder connection seats are fixed to the base, the air cylinder bodies are connected with the air cylinder connection seats, and the air cylinder hinge heads are mounted at the head ends of the air cylinder piston rods; rail notches are formed in the rail plates, and the rollers roll linearly in the rail notches; the manipulator structure comprises a double-lug plate, a power arm, grippers and a hinge shaft, the power arm is connected with the double-lug plate, a left power arm body and a right power arm body in the power arm are connected through the hinge shaft, and the grippers are arranged on the lower portions of the left power arm body and the right power arm body correspondingly. The structure is reasonable, safety and reliability are achieved, clamping force is large, the cost is low, and operation is convenient.

Description

technical field [0001] The invention relates to a device and a method, in particular to a device and a method for clamping castings, which belong to the field of iron mold sand-covered casting equipment. Background technique [0002] There are many clamping devices in industrial applications, and there are many types of them. In the field of sand-covered iron mold casting, clamping devices are required to grab castings from the sand box. At present, it is generally done manually, which is time-consuming and laborious. There is a safety hazard, and there is no conveniently operated clamping casting device at present. [0003] The publication date is June 3, 2015, and the Chinese patent with the publication number 104670899A discloses an invention patent named "casting removal device". The patent includes a telescopic hydraulic cylinder and an automatic adsorption device. The automatic adsorption device includes an electromagnet suction cup fixed at the end of the telescopic ...

AI Technical Summary

Problems solved by technology

The patent includes a telescopic hydraulic cylinder and an automatic adsorption device. The automatic adsorption device includes an electromagnet suction cup fixed at the end of the telescopic hydraulic cylinder telescopic rod and a telescopic contact switch connected with the electromagnet suction cup control circuit; the central processing of the telescopic hydraulic cylinder telescopic rod There is a columnar groove, and a contact groove is arranged at the bottom of the columnar groove; a contact is arranged at the bottom of the contact groove; although it is also patented to control the electromagnet sucker to absorb the steel casting by contacting and stretching the reset telescopic rod, but In actual use, it is suitable for steel castings, has limitations, and the operation is not stable and reliable enough
