Abstract

The invention relates to a revolving fixing and clamping device capable of improving processing accuracy. The revolving fixing and clamping device capable of improving the processing accuracy comprises a two-claw clamping disc, positioning blocks and a quick change lock; the two-claw clamping disc is provided with two clamping claws, each clamping claw is connected with a positioning block, and the inner wall of each positioning block is connected with an L-shaped installation plate; the two L-shaped installation plates are oppositely arranged, and the quick change lock is installed between the L-shaped installation plates; the quick change lock consists of a base and an upper cover, the upper cover is fastened onto the base, and one end of the upper cover and the base are installed in a hinged mode; and workpiece positioning grooves are formed in the inner side walls of the upper cover and the base, and a positioning column is installed on the workpiece positioning groove formed in the base. The revolving fixing and clamping device capable of improving the processing accuracy is reasonable in design, practical in structure, flexible in use and low in manufacturing cost, and can beinstalled on a lathe; and by using the device, the number of clamping times can be reduced, the workload of staff can be reduced, the product processing accuracy can be improved, the work efficiencycan be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a tooling fixture in the technical field of engine end cover faucet processing, in particular to a rotary fixed clamping device capable of improving machining accuracy. Background technique [0002] Such as figure 2 Middle 4 shows the engine end cover faucet, on which two ends are formed. In the existing production process, when processing the two ends, the workpiece is first installed on a tooling, and then processed One of the ends, after processing, remove the workpiece, install the workpiece on another tooling, and then process the other end. Because it needs to be turned twice and clamped twice, the error of clamping is increased, which makes it difficult to guarantee the machining accuracy of the workpiece, and the workpiece is easy to be turned off, resulting in an increase in the scrap rate and increasing the cost of the enterprise. In addition, multiple card loading also increases the workload of the staff. Content...
