the two sides of the clamp bottom plate are fixedly connected with mounting connecting plates, the upper ends of the mounting connecting plates are provided with second air cylinders, and the output ends of the two groups of second air cylinders are respectively connected with the two groups of clamping plates;

the use method of the engine water pump composite tool fixture table is as follows:

a: four pump covers to be processed are placed in a limiting groove on the upper end face of a clamp base plate, the top of each pump cover is higher than the limiting groove, then two groups of second cylinders are controlled by a controller to work, two groups of second cylinders are arranged to respectively push two groups of clamping plates to move, so that sliding blocks at the lower ends of the clamping plates slide in a fifth mounting groove, the arranged limiting plates can prevent the sliding blocks from moving out of the fifth mounting groove, rubber cushion blocks on the arranged buffering clamping plates are firstly contacted with the pump covers in the process that the clamping plates move towards the pump covers, the pump covers can be protected in the process of clamping the pump covers, damage in the clamping process of the clamping plates is prevented, first connecting convex blocks slide in the inner depths of the fixing grooves, first springs are arranged to be compressed, second movable rods are arranged to drive the buffer blocks to move towards the inner parts of the buffer block grooves on the second fixing rods, the two groups of third springs are compressed, and the first spring and the third spring are continuously compressed to realize that the two groups of buffer clamping plates are clamped and fixed, so that the pump cover can be clamped and fixed, and the pump cover can be prevented from being damaged by clamping;

b, after the step A is finished, starting the two groups of first air cylinders again to enable the arranged first air cylinders to respectively drive the sliding rods to move downwards, further enabling the four groups of limiting ring plates to move downwards until the four groups of limiting ring plates limit the tops of the four groups of pump covers in the central positions of the four groups of pump covers simultaneously, enabling the tops of the arranged pump covers to protrude out of the limiting ring plates, machining milling equipment such as a boring cutter on the tops of the pump covers, and enabling the four groups of limiting ring plates to fix the top ends of the pump covers;

c, after the step B is finished, clamping work is finished, if processing accidents happen when the pump cover is milled, the milling equipment firstly touches a protective circular ring inside a limiting circular ring plate, the arranged protective circular ring drives a supporting bottom plate to move downwards, the arranged supporting bottom plate drives a connecting bottom plate at the lower end of a fixed connecting rod to move downwards, the lower end of the connecting bottom plate further moves downwards through a connecting block connected with a fifth spring, the arranged connecting block extrudes a pressure sensor, the arranged pressure sensor senses pressure change and transmits signals, a controller is further arranged to control a hydraulic cylinder to work, the hydraulic cylinder drives a clamp bottom plate at the upper end of the supporting column to move downwards through a hydraulic telescopic rod, a first air cylinder is further controlled to work to drive a sliding rod to move downwards, the pump cover further moves downwards, and the pump cover is protected, and after the maintenance is finished, lifting the pump cover to continue processing.
