The invention discloses an inverted-T-shaped cross-shaped sliding table vertical five-axis machining center, and relates to the technical field of five-axis machining. The precision problem is solved. The machine specifically comprises a base, an X-axis linear guide rail, a saddle, a Y-axis linear guide rail, a rotary table supporting plate, a five-axis cradle rotary table, a stand column, a Z-axis linear guide rail, a spindle box and a vertical tool magazine, the saddle is connected with the base through the X-axis linear guide rail to achieve X-axis left-right movement, and the rotary table supporting plate is connected with the saddle through the Y-axis linear guide rail to achieve Y-axis front-back movement. The five-axis cradle rotary table is installed on the rotary table supporting plate to achieve A-axis and C-axis rotary motion, a stand column is installed on the base, and the spindle box is connected with the stand column through a Z-axis linear guide rail. Compared with a traditional vertical five-axis machining center, a cross-shaped sliding table structure is adopted, overhanging of the saddle and the workbench can be effectively reduced, when the center bears the weight and inertia of a five-axis cradle rotary table, the precision change in the operation process of a machine tool is small, and high-precision five-axis linkage machining of workpieces can be achieved.

According to the small-aperture intermittent deep hole machining technology, machining is conducted through a small-aperture intermittent deep hole machining tool set, and the small-aperture intermittent deep hole machining tool set comprises a first tool, a second tool, a third tool, a fourth tool and a fifth tool. When the first multi-blade supporting shaft and the second multi-blade supporting shaft are used for machining, the multi-blade supporting structure plays a supporting and guiding role in a front section hole, the overall machining rigidity and stability are enhanced, cutter breakage is avoided, the whole cutter composition cost is low, and machining of small-aperture intermittent deep holes can be efficiently and reliably completed.

The application discloses a display device, comprising a display device and a camera device, the camera device is fixed to the display device, the camera device comprises a rotating support and a camera module, a mounting piece of the rotating support is fixed on the back surface, one end of a first rotating piece of the rotating support is hinged to the mounting piece, one end of a second rotating piece of the rotating support is hinged to the other end of the first rotating piece. The camera module is hinged to the other end of the second rotating piece, and the camera module is configured to move relative to the mounting piece under the rotation of the rotating support. The two ends of the first rotating piece and the second rotating piece hinged to each other are provided with avoiding structures, the avoiding structures are configured to avoid the relative rotation of the first rotating piece and the second rotating piece, so that the angle of the relative rotation of the second rotating piece and the first rotating piece is not less than 180°. The display device of the application can make the adjustable range of the camera device relative to the display device larger, and then adapt to display devices of various thickness sizes.

The utility model relates to manual center stand technical field, concretely relates to a manual center stand for thin wall processing, aims at solving the problem that manual center stand space continuously occupies and overall interference range is bigger. Its technical scheme main points are: including center stand base and setting first arm body, second arm body and third arm body on center stand base, center stand base is L shape, the axis line of first arm body, second arm body and third arm body is located same plane and meets in same point, and center stand base is equipped with first arm adjusting mechanism, second arm adjusting mechanism and third arm adjusting mechanism, the improved manual center stand keeps open state under the non clamping state of the clamping arm, improves the convenience and operation flexibility of overall processing environment, and the manual center stand is set in the position more behind than cutter head, reduces the protruding part, solves the position conflict problem of manual center stand and cutter head.

The invention relates to the technical field of massage equipment, in particular to a massage device and an in-body massager. The massage device comprises a massage main body and a driving assembly, the massage body comprises a massage part and a grabbing part which are connected, the end, away from the grabbing part, of the massage part bends and extends along an arc line, a massage head is arranged in a concave position of the massage part, and the height of the massage head is larger than the depth of the concave position. The driving assembly is arranged in the massage body, and the action end of the driving assembly is connected with the massage head. The massage head in the massage device is arranged in the concave position formed by bending the massage part, the concave position can well hide the massage head and reduce the protruding part of the massage head so as to reduce stimulation of the massage head to a patient when the massage head is inserted, and therefore discomfort caused by the massage head is reduced, secondary injury is avoided, and meanwhile the massage device is convenient to use. The height of the massage head is larger than the depth of the sunken position, so that the massage face of the massage head can make contact with and act on the body of the patient, and the corresponding rehabilitation and treatment purposes are achieved.
