Description
Technical field
The utility model is related to the elastomer strain regions sandblasting polishing of abrasive blast equipment field, more particularly to a kind of sensor to set
It is standby.
Background technology
In weighing sensor technology, by strain ga(u)ge paste make on flexible member other side know be securely joined with for
One entirety, its basis is that flexible member paster must have the surface roughness for meeting bonding requirement, can so go out decontamination
Dirt increases bonding area, and energy activating surface, is conducive to strain adhesive to infiltrate.So, it is necessary to bullet before strain gauge is pasted
The bonding zone of gonosome strain gauge carries out technique for grinding.
Existing technique for grinding is broadly divided into two kinds, and one kind is manual grinding, i.e., carried out by the way of artificial by sand paper
Polishing.Another way is artificial sandblasting polishing, i.e. the hand-held sand-blasting gun of operating personnel is polished elastomer.Its shortcoming exists
In automaticity is low, and polishing quality is related to the experience level of operating personnel, and polishing uniformity is poor.
Bonding zone is only needed to be polished due to Weighing sensor elastomer, without being to work as the treatment of other workpiece surfaces
Part is integrally polished.Prior art is polished using man-hour manually hand-held sand-blasting gun, it is to avoid be polished to other non-Sanding Areas, and it lacks
Point is that automaticity is low, and polishing quality is related to the experience level of operating personnel, and polishing uniformity is poor.

Finished surface, reaches expected processing purpose.In suction-type dry blasting machine, compressed air is both feed power and jet
Accelerate power.
Forced abrasive blast equipment is typically made up of four systemses, i.e. pressurized tank, medium dynamical system, pipe-line system, control
System.Forced dry blasting machine is the operating pressure set up in pressurized tank by compressed air with compressed air as power, will
Abrasive material is pressed into sediment transport Guan Bingjing nozzles and projects by the valve that shakes out, and is ejected into surface to be machined and reaches expected processing mesh.In press-in
In formula dry blasting machine, compressed air is both feed power and the acceleration power of jet.
Liquid sandblasting machine is typically made up of five systems, i.e. structural system, medium dynamical system, pipe-line system, control system
System and accessory system.Liquid sandblasting machine is the feed power using grinding fluid as grinding fluid, by grinding fluid pump by the grinding fluid for stirring
(mixed liquor of abrasive material and water) is transported in spray gun.Compressed air enters spray gun as the acceleration power of grinding fluid by appendix,
In spray gun, compressed air accelerates to the grinding fluid for entering spray gun, and is projected through nozzle, be ejected into surface to be machined reach it is expected
Processing purpose.In liquid sandblasting machine, grinding fluid pump is feed power, and compressed air is acceleration power.
Guangzhou receive the production of amber sandblast machine equipment Co., Ltd NP1310-12A models sand-blasting machine for conveying-type it is complete from
Dynamic sand-blasting machine, including main frame, sandblasting cabin, pendulous device, conveying device, sand material recovery system, dust pelletizing system, electrical control.Its
