Automatic ball grinding machine

Abstract

The invention discloses an automatic ball grinding machine. The automatic ball grinding machine comprises a clamping mechanism for fixing balls, a swing mechanism for driving the clamping mechanism to do reciprocated swing in the horizontal direction and a grinding head mechanism for grinding the balls; the grinding head mechanism and the clamping mechanism are arranged in a staggered manner, and a clamping mechanism is connected to the swing mechanism; the grinding head mechanism comprises a transverse rail plate which is provided with a first motor and a second motor, the first motor and the second motor are oppositely arranged in a linear manner, the first motor and the second motor are each provided with a tool piece and a clamping and grinding head, and each clamping and grinding head is connected with the corresponding tool piece; and the clamping mechanism comprises a longitudinal rail plate and a third motor arranged on the longitudinal rail plate, and a rotary fixing column is connected to an output shaft of the third motor in a linked manner; and a rotation shaft base is fixedly connected to the position below the longitudinal rail plate. All ball face even and automatic grinding is achieved, the production efficiency is improved, and the machining effect and the machining quality are remarkably improved.

Description

technical field [0001] The invention relates to the field of valve equipment, in particular to an automatic ball grinding machine. Background technique [0002] In order to make the ball valve meet the corresponding sealing performance requirements, it is usually necessary to grind the ball of the ball valve. At present, our domestic enterprises usually grind the spheres by hand, which has the disadvantages of low processing efficiency and poor quality, while foreign automatic grinding machines have the problems of complex structure and high price. In order to solve this problem, a kind of grinding machine with relatively simple structure and relatively low price has been developed. However, the grinding quality of this type of grinding machine is not good, and the spheres are often ground into left and right surfaces with obvious differences, and the spherical surface cannot be realized. Comprehensive and balanced grinding will affect the performance of the ball valve, or ...

Problems solved by technology

At present, our domestic enterprises usually grind the spheres manually, which has the disadvantages of low processing efficiency and poor quality, while foreign automatic grinding machines have the problems of complex structure and high price

In order to solve this problem, a kind of grinding machine with relatively simple structure and relatively low price has been developed. However, the grinding quality of this type of grinding machine is not good, and the spheres are often ground into left and right surfaces with obvious differences, and the spherical surface cannot be realized. Comprehensive and balanced grinding will affect the performance of the ball valve, or some grinding machines are only semi-automatic and require more manual operations, so there are still some shortcomings in their processing efficiency and production cost.
