The present application relates to the field of fixture design for machine tools, in particular to a machine tool clamping force measuring clamp plate system and a method for measuring clamping force using the same. The system is composed of a clamp plate, a tail support device and a pressure regulating device. The clamp plate is a whole plate body and has an axisymmetric structure. A boss is arranged in the central region of the clamp plate and serves as a force beam. A through hole is arranged in the central region of the force beam. The clamp plate body is divided into a force transmission beam, a sensing beam and a contact beam region. The length direction edge region is the force transmission beam, the width direction edge region is the contact beam, and the remaining middle region is the sensing beam. The sensing beam is separated from the edge force transmission beam through the long holes on its two sides. Four strain gauges are fixed on the surface of the sensing beam on one side of the through hole. The four strain gauges are connected to form a Wheatstone bridge circuit. The present application solves the defects and limitations of traditional clamp plates that cannot control clamping force, preventing processing errors and surface defects caused by improper clamping force application.

A method for preparing a binary formula for Dai pottery clay and its application is disclosed. The method involves taking Dai pottery clay from the Honghe River basin, five-colored clay from Honghe County, and charcoal powder. The Dai pottery clay and five-colored clay are sun-dried and weathered for at least three months. The Dai pottery clay from the Honghe River basin has a SiO2 content of not less than 50%, an Al2O3 content of not less than 15%, an Fe2O3 content of not less than 10%, and a loss on ignition of less than 10%. The five-colored clay from Honghe County has a SiO2 content of 72-82%, an Al2O3 content of 9-12%, and an Fe2O3 content of 3-5%. The method involves soaking the Dai pottery clay and five-colored clay in water until fully saturated, then ball-milling them. The slurry is sieved, and then charcoal powder is added. After stirring evenly, the clay is pressed to drain water and then kneaded to remove air. This invention can improve the throwing and molding performance of Dai pottery clay, increase the sintering temperature and the density and strength of its structure, and reduce the burn-off rate.

The invention discloses a method for manually stripping an In column of an 8-inch reading circuit. The method comprises the following steps: putting a low-corrosivity organic solvent into a specially designed quartz soaking tank to remove photoresist; fixing an 8-inch reading circuit chip on a special clamp, holding a clamp handle by hand to vertically place the clamp and the chip into the quartz soaking tank, and enabling the chip to be completely immersed in the stripping liquid; inclining the clamp towards one surface with the reading circuit, wherein the front surface of the reading circuit faces downwards; after soaking for 4 hours, a medical injector is used for sucking stripping liquid to spray and wash the edge of the front surface of the reading circuit on the clamp, so that In on the surface is bulged and is separated from the chip, and tweezers are used for clamping away the bulged In; after stripping is completed, the front face and the back face of the reading circuit are washed; finally, putting the chip into a drying oven, and drying at 100 DEG C for 10 minutes; scratch and deformation of the In column are obviously reduced, and stripping efficiency and yield are improved. Through inclined clamp design and pressure control, In particle falling and mechanical stress are avoided.

This invention relates to the field of welding fume purification technology, and discloses a welding fume purification system and method for memory module manufacturing. The welding fume purification system for memory module manufacturing includes a welding equipment body with several suction hoods symmetrically distributed on the body. A horizontal pipe is connected to the outlet of each suction hood, and a first vertical pipe is located at the bottom of the horizontal pipe. This welding fume purification system for memory module manufacturing extends the residence time of the fume in the first vertical pipe through staggered diversion plates, allowing it to fully contact the cooled pipe wall and initially reduce the fume temperature. This significantly slows down the oxidation reaction rate between metal oxides and the filter cartridge substrate, reducing the degree of filter cartridge corrosion and extending its service life. Simultaneously, the stable low-temperature environment prevents the filter cartridge from failing to seal due to thermal expansion and contraction, ensuring filtration accuracy while effectively preventing secondary pollution caused by leakage of unfiltered fume.
