Problems solved by technology
[0003] However, the valve seat welding and positioning devices currently on the market require the operator to manually adjust and clamp and fix, which increases the labor force, is time-consuming and laborious, and is not easy to clamp the valve seat, and cannot accurately position the valve seat. The positioning and clamping effect of the valve seat is not stable enough, and it is easy to slide. Therefore, we propose a valve seat welding positioning device to solve the above problems

The present invention discloses a valve base welding and positioning device, which belongs to the technical field of mechanical processing. The valve base welding and positioning device comprises a base, wherein an arc groove is arranged in the base; the upper part of the arc groove is fixedly connected with a lower clamping block through rubber blocks; a fixing plate is fixedly connected to the upper part of the base; a first sliding chute is arranged in one side of the fixing plate and a second sliding chute is arranged in the other side of the fixing plate; a sliding rod is arranged in thefirst sliding chute; the sliding rod is slidably connected with a connecting rod through a first sliding block; and one end, far away from the first sliding block, of the connecting rod is in threadedconnection with a threaded rod through a second sliding block. The valve base welding and positioning device of the present invention is equipped with a brake motor, a third rotating shaft, a transmission belt and a second turntable. The brake motor is arranged to drive a first turntable to rotate through the third rotating shaft, the first turntable drives the transmission belt to rotate the second turntable, and the second turntable drives the threaded rod to rotate through a first bearing, thereby leaving out manual rotation and greatly saving manpower.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a valve seat welding positioning device. Background technique [0002] The valve seat is a detachable surface part in the valve, which is used to support the fully closed position of the valve core and constitute a sealing pair. Generally, the diameter of the valve seat is the maximum flow diameter of the valve. The role of the valve seat is mainly to connect the inlet and outlet pipes of the valve, forming a The chamber completes the guidance of the fluid in the valve, fixes the valve operating mechanism, guides the directional movement of the valve disc, and bears the pressure of the fluid in the valve, etc. [0003] However, the valve seat welding and positioning devices currently on the market require the operator to manually adjust and clamp and fix, which increases the labor force, and is time-consuming and laborious. At the same time, it is difficult to clamp...
