Description

For the weighing sensor workpiece clip of double sand-blasting gun lateral spray type abrasive blast equipments

Technical field

The utility model is related to abrasive blast equipment field, the workpiece clip of more particularly to a kind of abrasive blast equipment.

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.

In abrasive blast equipment field, disclose the abrasive blast equipment of diversified forms in the prior art, including suction-type, it is forced, Liquid-type.

Suction-type dry blasting machine is typically made up of six systems, i.e., structural system, medium dynamical system, pipe-line system, remove Dirt system, control system and accessory system.Its operation principle is that suction-type dry blasting machine is with compressed air as power, by gas The negative pressure that the high-speed motion of stream is formed in spray gun, by abrasive material by sediment transport pipe suck spray gun and through nozzle project, be ejected into by 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 Principle is directly to take out sand formula sandblasting using upper whirlwind sub-sand system, i.e., using compressed air, flow at high speed forms negative pressure in spray gun Ejector action is produced, the sand material in cyclone separator is sucked in spray gun by sediment transport pipe, then with compressed air by spraying Mouth is ejected into workpiece surface at a high speed, reaches the purpose of sandblasting, and sand material and dust are automatically separated, and dust is collected into dust cleaning case.

As shown in figure 1, Chinese patent CN103231314B also discloses a kind of integral type sand-blasting machine, including sandblasting engine space, Rotating disk induction system, spray gun swing mechanism, compressed air system, sand material recovery system, dust pelletizing system and electric-control system, each is System mechanism use unitary design, it is ensured that the connection of each system authority is compacter, and whole machine occupies little space, installation cost and Cost of transportation is low, also causes that the work operating of sand-blasting machine is more smooth, and automation and mechanization degree are high, and then improve sandblasting The processing efficiency and sandblasting effect of machine.

As shown in Fig. 2 Chinese patent CN2010106166623 discloses a kind of abrasive blast equipment, it includes working bin, workpiece Conveying arrangement, abrasive material transfer separation device and dust arrester, working bin include chamber, spray gun and the first track, the front of chamber On be provided with several observation windows, the lower section of each observation window sets a pair of sandblasting gloves, and the side of chamber is equiped with operation door, Workpiece transport device is located at the side of operation door, and it includes defeated go-cart and carries turntable, and being provided with transport trolley can be with first Second track of orbital docking, supporting part is provided with several can be in the first track and the pulley of the second sliding on rails, abrasive material Transfer separation device includes conveying mechanism and separator, and conveying mechanism is connected with chamber, separator and meanwhile with conveying mechanism and Spray gun is connected, and dust arrester includes dust cleaning case and blower fan, and dust cleaning case is connected with separator.

Workpiece entirety sand blasted surface treatment is applied to because prior art abrasive blast equipment is mainly, and for weighing sensor For elastomer, only need to be to bonding strain panel region, if additionally, uncorrelated region is carried out into blasting treatment can also influence bullet Gonosome strain property, prior art can not well meet such as Weighing sensor elastomer to be carried out at local sandblasting to workpiece Reason.

Additionally, prior art sandblasting polishing workpiece is usually one side sandblasting polishing, and Weighing sensor elastomer general two There is blind hole sand blasted area in face.Prior art can not once polish the two sides of elastomer.

If Figure 11 is common blind hole type elastomer 3, the inner bottom part of the blind hole 31 on its two sides need to be polished.Blind hole type When elastomer strain regions are polished, blind hole easily accumulates sand grains, the impact dynamics of follow-up shot blasting particles is influenceed, at influence sand blasted surface Reason efficiency.

Utility model content

In view of the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of for double The weighing sensor workpiece clip of sand-blasting gun lateral spray type abrasive blast equipment, can carry workpiece and using in sandblasting operating line.
