The invention relates to a high-speed precise punch press, which is provided with an eight-face positioning mechanism, a dual-nut slider structure and a dual-elbow joint transmission structure. The high-speed precise punch press is reasonable in structural design, very simple in operation and high in work efficiency, the adjusting and die adjusting are more convenient, operation personnel can operate the punch press without the need of professional skills of professional punch press maintaining staff, the parallelism of vertical motion and precision of perpendicularity of a slider can be ensured, the precision of the punch press is improved, meanwhile, the anti-fatigue performance of the machine is improved, the work stability is improved, the machine can be normally operated at higher speed, the production time of products is shortened and the cost is saved.

The invention provides a multi-drill high pressure jet agitation based anti-seepage reinforcing equipment and a construction method thereof. The equipment comprises a drilling machine, a stirring machine and a guniting system connected between the drilling machine and the stirring machine, wherein the drilling machine comprises a drill rig fixed on a trolley, an operation board, an actuating mechanism, a speed change mechanism, a transmission mechanism and a turnplate; three to five drill stems are arranged; the lower end of the drill stem is provided with a high pressure drill; the guniting system is a high pressure guniting system, and comprises a high pressure slurry pump with a pressure indicator and a high pressure slurry delivery pipe; and one end of the high pressure slurry delivery pipe is communicated with a slurry delivery pore canal through a high pressure jet tap, while the other end is communicated with a slurry outlet of the stirring machine. The equipment integrates drilling, hoisting and high pressure jet stirring into a whole, improves the anti-seepage factor and verticality of a seepage proof wall, improves the vertical accuracy of drilling and the depth of bore holes, and solves construction defects of vents, deflection, jet nozzle blockage, cold seam, soil mixture of the seepage proof wall and the like.

The invention relates to a radial verticality detection platform of single crystal pole for detecting the radial verticality of a single-wafer rod in photovoltaic industry. The radial verticality detection platform comprises a bottom plate, (10), a dial (11), a pillar (2) with a calibrated scale (2-1), a depth measuring scale (7) and an indexing table (8), wherein the lower end of the pillar (2) is provided with a base(1); the base (1) is fixed on the bottom plate (10); the dial (11) is rotatably supported on the bottom plate (10); the depth measuring scale (7) and the indexing table (8) are movably arranged on the pillar (2); and the depth measuring scale (7) is arranged below the indexing table (8). The invention not only ensures the vertical precision of the single-wafer rod but also ensures the accuracy of alignment of the single-wafer rod and does not need to detect circular run out for the second time.

The invention provides a section-steel-column support frame construction method for a super-high-rise-building frame column. The method includes the steps that 1, a support frame is made; 2, bolts arefixedly arranged on the support frame through a calibration steel sleeve plate; 3, a concrete cushion of a building structure bottom plate is poured, and embedded parts are embedded; 4, the support frame is lifted and fixed; 5, lower reinforcing steel bars of the building structure bottom plate are bound and welded to the support frame; 6, slant supports are welded to the lower portion of the support frame; 7, a first steel column is fixedly installed on the support frame; 8, positions of section steel columns are corrected, and the section steel columns are anchored and fixed; 9, upper reinforcing steel bars of the building structure bottom plate are bound, and bottom plate concrete is poured; 10, a second steel column and rear steel columns are fixedly installed. According to the section-steel-column support frame construction method for the super-high-rise-building frame column, construction is easy, convenient, safe and reliable, the construction quality is easy to control, the embedded quality of the section steel columns in a foundation bottom plate or a ground beam can be guaranteed, and three problems that in a construction method for section steel columns of a traditionalbuilding structure frame column, the anchor bolt accuracy is poor, the stability of the support structure is poor, and as key construction procedures are occupied, the construction period is influenced are effectively solved.

A precision compact 3D printer powder supply mechanism and transmission method, including a lower cylinder body, a spline assembly, a screw and a motor, a support is provided above the lower cylinder body; the spline assembly includes a spline shaft and Spline sleeve, the spline sleeve is fixed on the bottom surface of the support member, the spline shaft can be inserted into the spline sleeve for axial movement, and one end of the spline shaft protrudes from the lower cylinder body The screw rod includes a screw rod and a screw nut, the screw nut is arranged in the lower cylinder body, the screw nut is fixed on the bottom end of the spline shaft, the screw rod and the screw rod The nut is threaded, the screw rod extends into the spline shaft, and the screw rod is connected with the servo motor. The invention uses the connection between the screw rod and the spline assembly, and the transmission between the two. The powder supply mechanism has high linear motion accuracy, which meets the transmission accuracy requirements of the 3D printer. In addition, extending the screw rod into the spline assembly has the advantage that the arrangement space of the transmission structure is small.
