The invention discloses an electric clamp capable of rapidly changing the clamping surface. The electric clamp comprises a base. A first driving motor and a second driving motor are oppositely arranged at the left end and the right end of the upper surface of the base respectively. The output ends of the first driving motor and the second driving motor are connected with a first electric push rod and a second electric push rod respectively. A sliding groove is formed in the upper surface of the base. Two sliding blocks are arranged in the sliding groove. Each sliding block is provided with a vertical rotary shaft. A clamping plate is fixedly connected with the corresponding rotary shaft. One face of each clamping plate is planar, and the other face of the clamping plate is curved. According to the electric clamp capable of rapidly changing the clamping surface, the problem that clamping of a plane and a curved surface is difficult to achieve through a single clamp in the prior art is solved, and the purpose for clamping planar workpieces and workpieces with curved surfaces through the same clamp is achieved.

The invention relates to a reversible emulsifier for oilfield drilling fluid, in particular discloses a recyclable pH value responsive reversible emulsifier for oilfield drilling fluid. The technical solution is that the raw material components include the following: 10%-90% of the water phase, 10%-90% of the oil phase, 1.0%-2.5% of a recyclable pH-responsive reversible emulsifier, and the oil phase is white oil or diesel; the aqueous phase is CaCl at a concentration between 10%‑40% 2 aqueous solution. Its beneficial effect is: the reversible emulsion of the emulsifier has good stability, and after the reversible emulsifier loses its reversible transformation ability after repeated use, the modified magnetic nanoparticles that have lost their reversible transformation ability can be removed by building a high-intensity magnetic field. Separation avoids its influence on the reversible transformation ability of the reversible emulsion system. At the same time, the recovered magnetic nanoparticles can be used as a reversible emulsifier to stabilize the reversible emulsion after acid contact treatment.

The invention discloses an automatic capped fastener positioner. The automatic capped fastener positioner is characterized in that the automatic capped fastener positioner comprises a base plate, a guide seat, a pushing assembly, a guide assembly and a positioning block, the guide seat is fixedly arranged on the base plate and provided with a guide way, the pushing assembly and the guide assembly are respectively arranged on both ends of the guide way, the pushing assembly comprises a pushing rod which can linearly move in the guide way, the end of the pushing rod is a magnetic attracting part, the guiding assembly comprises a positioning plate, which is provided with a conical positioning guide hole, the inlet end and outlet end of the positioning guide hole are respectively aimed at the guide way and the positioning block, and the positioning block is provided with a fastener-positioning hole. The automatic capped fastener positioner can automatically position a fastener, thus making automated continuous batch production possible, moreover, positioning is accurate, the structure is simple, and the automatic capped fastener positioner is easy to put into practice. The automatic capped fastener positioner can directionally move the automatically positioned fastener, consequently, the fastener can be conveniently transferred between two pieces of equipment, and an automated assembly line can be conveniently put into practice.
