The invention relates to a universal mandrel groove grinding device, in particular to a universal mandrel adjustable groove grinding device and a groove grinding method, and aims at solving the technical problems that when an existing clamp is used for grinding sliding grooves of a universal mandrel, it is difficult to guarantee that the included angle between the groove and the central axis of the mandrel meets the technical requirement, indexing of the three sliding grooves is inaccurate, and the repeated positioning precision is low. The device comprises a wedge-shaped bottom plate, and a first clamping mechanism, an indexing mechanism, a supporting mechanism and a second clamping mechanism which are arranged on the wedge-shaped bottom plate, the first clamping mechanism and the second clamping mechanism are used for positioning the universal mandrel to be subjected to groove grinding from the two ends in the axial direction correspondingly. The supporting mechanism is used for supporting and fixing a universal mandrel of a to-be-ground groove; the indexing mechanism comprises a tooth aligning pin seat, a tooth aligning pin and an indexing ring; the tooth aligning pin is mounted on the tooth aligning pin seat, and positioning teeth are arranged at the top of the tooth aligning pin; a plurality of jackscrews are arranged on the indexing ring; a positioning groove is formed in the peripheral surface of the indexing ring; and the positioning teeth are matched with the positioning grooves so as to realize circumferential positioning of the universal mandrel to be subjected to groove grinding.

The utility model relates to cement setting detection technical field discloses a cement setting detection device, including base, support and detection seat, the support is slidably installed on the base, the support tail end is connected with the detection seat, is seted up in the base and has installation cavity, two support rods are installed in the installation cavity, rotatoryly installed rotatory shaft has on two support rods, the cam is assembled on rotatory shaft, rotatory shaft is installed in the installation cavity, rotatoryly installed rotary disc has on rotatory shaft, the rotary disc bottom is evenly distributed with several rollers, and the roller is adapted with the cam. The utility model drives the cam roller through the knob drive rotatory shaft and drives the rotary disc, makes the detection needle around the test mould cover circumferential motion, avoids the repeated detection, ensures the detection point even distribution, through the sliding support and lock nut combination, can flexibly adjust test mould cover and detection needle distance, easy operation, significantly improves the detection efficiency and the device practicality.

The utility model discloses an efficient microsphere screening device which is characterized in that the efficient microsphere screening device comprises a circulation tank, a first stirrer is arranged on one side of the bottom of the circulation tank, the bottom end of the circulation tank is connected with a microsphere screening assembly through a discharging pipe, and a rotor pump and a mass flow meter are arranged on the discharging pipe between the microsphere screening assembly and the circulation tank; and the top end of the microsphere screening assembly is connected with the feed port of the circulating tank through a return pipe. The stirring device is arranged in the screening cavity, so that uniform distribution of the microspheres is ensured, and local accumulation is avoided. And the automation degree of the equipment is further improved through the side wall automatic discharging design, the screened microspheres can be automatically discharged through a side wall outlet, manual intervention is reduced, and the production efficiency is improved.
