Fourth-shaft double-station hydraulic clamp of thin-wall shell of wheat seed sowing device

Abstract

The invention provides a fourth-shaft double-station hydraulic clamp for a thin-wall shell of a wheat seed sowing device, the fourth-shaft double-station hydraulic clamp comprises a fourth-shaft hydraulic clamp, the fourth-shaft hydraulic clamp comprises a bottom plate, a gap bridge plate, a first clamping mechanism and a second clamping mechanism, the gap bridge plate is fixed on the bottom plate through a locking bolt; the first clamping mechanism and the second clamping mechanism are arranged on the gap bridge plate; the first clamping mechanism and the second clamping mechanism are both used for positioning and clamping workpieces. According to the clamp, rapid positioning can be achieved, two seed-metering device shell workpieces can be clamped at the same time at a time, meanwhile, assembling and disassembling are rapid, the positioning precision is high, the working efficiency and the machining quality are effectively improved, and the production cost and the rejection rate are reduced.

Description

technical field [0001] The invention belongs to the technical field of hydraulic clamps, in particular to a fourth-axis double-station hydraulic clamp for a thin-walled casing of a wheat seed metering device. Background technique [0002] Wheat precision sowing has always been a worldwide problem, and the key part to achieve precision sowing is the seed meter, which ensures that the seeds can be single-grained and discharged regularly, reduces the amount of sowing, and enables the seeds to have an accurate sowing depth. Row spacing and plant spacing, while improving the quality of sowing, seeds are easily damaged during the process of sending and sorting seeds, so this has certain requirements for the quality of the seed metering device. [0003] There is an existing wheat seed metering device shell. During the working process of the seed metering device, it is necessary to ensure that the wheat seeds will not be damaged due to the surface quality of the seed metering device...

AI Technical Summary

Problems solved by technology

[0003] There is an existing wheat seed metering device shell. During the working process of the seed metering device, it is necessary to ensure that the wheat seeds will not be damaged due to the surface quality of the seed metering device shell. Therefore, the workpiece of the seed metering device shell (hereinafter referred to as the workpiece) The processing quality has certain requirements. Although the existing fixture can hold the workpiece, it can be further machined, but the clamping is not reliable, the positioning is not accurate, the thin-walled parts are easily deformed during the processing, and the installation process is cumbersome.
