The invention discloses a micro double-spindle false tooth repair machine. The false tooth repair machine comprises a base (40) and a first electric spindle system (20), a second electric spindle system (90), electric cabinets (10) and a workpiece rotating mechanism (70) which are arranged on the base (40). The false tooth repair machine is characterized in that: the first electric spindle system (20) and the second electric spindle system (90) are arranged coaxially, and cutters arranged on the first electric spindle system (20) and the second electric spindle system (90) and a workpiece arranged on the workpiece rotating mechanism (70) extend into a machining space (60) and are arranged vertically in a horizontal plane; the first electric spindle system (20) and the second electric spindle system (90) are arranged on respective X-axial feeding mechanisms (30); the workpiece rotating mechanism (70) is arranged on a Y-axis feeding mechanism (100), the Y-axis feeding mechanism (100) is arranged on a Z-axis feeding mechanism (120), and the Z-axis feeding mechanism (120) is arranged on the base (40); and a tool magazine system (50) is also arranged on the Y-axis feeding mechanism (100). The false tooth repair machine has the advantages of simple structure, small volume, high machining precision and convenience in operation.

The invention discloses a tomography system inside a blood vessel. The tomography system comprises an imaging catheter, an optical fiber movement controller, a tomography module, a data collecting module and a data processing and displaying module which are connected in sequence. The light emitted by the tomography module is transmitted to the imaging catheter through the optical fiber movement controller, the light is concentrated on a target blood vessel wall through the imaging catheter, and the optical fiber movement controller drives the imaging catheter to conduct rectilinear motion inside a target blood vessel at the same time of rotating at a high speed. The reflected light of different layers of the target blood vessel wall is collected and transmitted to the optical fiber movement controller and the tomography module in sequence by the imaging catheter, the tomography module demodulates the received reflected light into intensity information and then converts the intensity information into electrical signals, the data collecting module collects and transmits the electrical signals to the data processing and displaying module, and the data processing and displaying module processes, generates and displays cross-section image information of the blood vessel. By means of the tomography system inside the blood vessel, the high-speed tomography of the blood vessel can be achieved.

The invention provides a cam contour detecting system based on a direct drive motor. The cam contour detecting system has the advantages of simple structure, high detection accuracy and higher efficiency and comprises a direct drive motor, a mandrel coaxially and fixedly arranged on a rotor of the direct drive motor and used for driving a cam to rotate synchronously and coaxially, a screwpair horizontally arranged at one side of the cam, a laser measuring head on a traveling nut of the screwpair, a grating ruler displacement sensor for measuring the horizontal displacement of the traveling nut, a circular grating arranged in the direct drive motor fixing seat and used for detecting the rotational angle of the rotor and an industrial control computer; and the industrial control computer isused for controlling the direct drive motor and the screwpair to act, and obtaining the outer contour data of the cam, according to the data measured by the laser measuring head, the grating ruler displacement sensor and the circular grating.

The invention relates to a special lifting adjusting mechanism for a bottle-making machine pressed mouth forming device, wherein the special lifting adjusting mechanism comprises a machine frame, and a driving mechanism for driving a lifting shaft, the lifting shaft and a lifting sleeve which are successively assembled on the machine seat; the top end of the lifting shaft and a base of the pressed mouth forming mechanism are connected into a whole, and output of the driving mechanism is in thread or intertooth meshing connection with the lifting shaft. Through a rotary driving way of thread or intertooth meshing of the driving mechanism, the adjusting mechanism adopts a direct-driving linear adjusting control way for height positioning of the lifting shaft, the displacement amount of the lifting shaft can be accurately adjusted, accurate positioning of the height of the pressed mouth forming device is ensured, and the product qualified rate of pressed mouth forming of a bottle body reaches more than or equal to 98%. The stable and reliable production quality and production efficiency of a bottle-making machine are further improved.
