This utility model relates to the field of electric motor technology, specifically disclosing a rack guide structure, including a guide sleeve with a guide channel. The cross-sectional shape of the guide channel is non-circular or non-arc, and the guide wall of the guide channel includes at least one planar segment. The guide channel is used to cooperate with an anti-rotation part on the rack. The cross-sectional shape of the anti-rotation part is adapted to the shape of the guide channel, allowing the rack to reciprocate along the guide channel. A pump electric motor includes a motor body, a gear, and a rack. The motor body drives the gear to rotate, and the rack meshes with the gear, serving as the reciprocating drive source for the pump body. It also includes the aforementioned rack guide structure. The guide sleeve in the rack guide structure is fixedly installed on the housing of the motor body, and the anti-rotation part of the rack cooperates with the guide channel of the guide sleeve. This solution addresses the problem of easy wear caused by rack deflection or tilting in current rack-output motors.

The logistics sorting robot comprises a bottom plate, a second vehicle body layer, a ball storage disc and a sliding way, an identification mark is arranged on the bottom plate, the second vehicle body layer is arranged above the bottom plate, a mechanical arm is arranged on the second vehicle body layer, a mechanical claw is arranged at the tail end of the mechanical arm, and the ball storage disc and the sliding way are sequentially arranged above the second vehicle body layer. A plurality of groups of ball blocking piles are uniformly arranged on the ball storage disc in the circumferential direction, and workpiece fixing holes are formed in the inner sides of each group of ball blocking piles; when the ball storage disc rotates, the ball blocking pile passes through the lower portion of an outlet of the sliding way, and through a mechanical claw at the front end of the mechanical arm, workpieces are pulled down from the plane terrain or grabbed, hit a baffle additionally arranged on the sliding way or directly fall into the inclined face of the sliding way. And under the action of gravity, the workpieces roll downwards to fall into a bottom rail and then move to a temporary workpiece storage position on the ball storage disc, so that the efficiency and the success rate of sorting the workpieces and marking information are greatly improved in the process of shifting the workpieces.

The present invention provides a precession magnetic field generating device for a spin echo quasi-bullet neutron scattering spectrometer, which provides a precession magnetic field with high uniformity for the precession of polarized neutrons. The device uses two pairs of Helmholtz coils and an online adjustment mechanism to generate a cylindrical magnetic field; the two pairs of Helmholtz coils are coaxially placed inside and outside, and the currents passing through them are opposite, so that the magnetic field decays rapidly at the edge, reducing the interference of the redundant stray magnetic field on the neutron path; the online adjustment mechanism can adjust the geometric structure of the coil spacing and angle when the neutron beam flow path is opened, and adjust in real time according to the signal results to provide the magnetic field required for the precession of polarized neutrons, and cooperate with the spin echo quasi-bullet neutron scattering spectrometer to greatly improve the energy resolution of neutron scattering, and is used to analyze the dynamic behavior in the range of picoseconds to nanoseconds and angstroms to nanometers in the test material.

The utility model relates to the technical field of wine brewing equipment, and discloses a distiller's yeast blanking device which comprises a track, a moving unit, a lifting unit, a hook, a hanging bracket, a first driver and a second driver, the hanging bracket comprises a support, a hanging ring, a first limiting block and a second limiting block, and when the hanging bracket is hooked by the hook, a limiting gap D1 between the first limiting block and the second limiting block limits the hook to rotate around the axis of the hanging ring, so that the hanging bracket cannot swing in the circumferential direction of the hanging ring; the hanging bracket is manually adjusted until the axis of the hanging ring is perpendicular to the length direction of the track, so that the hanging bracket can be prevented from greatly shaking in the moving direction in the moving process, and the problems that the hanging bracket needs to be transported, moved and positioned along the track, and the hanging bracket greatly shakes or inclines in the length direction of the track when the moving unit accelerates and decelerates are solved. And the hanging bracket or the materials on the hanging bracket accidentally fall off or are impacted.

The utility model relates to the technical field of generator disassembling and assembling tools, in particular to a supporting assembly for disassembling and assembling a generator sealing tile chamber. The supporting assembly is connected with the axial end face of the lower half sealing tile chamber, one end face of the supporting assembly is the arc-shaped face, and the arc-shaped face can be connected to the periphery of the stator shaft in a sliding mode, so that when the supporting assembly is connected with the lower half sealing tile chamber, the arc-shaped face abuts against the periphery of the stator shaft to support the lower half sealing tile chamber on the stator shaft; therefore, a reliable connecting and supporting structure is provided for the lower half sealing tile chamber which is not supported by the inner ring. Compared with the situation that in the prior art, effective constraint is lacked when the lower half sealing tile chamber is disassembled, the supporting assembly can effectively limit inclination of the lower half bearing chamber due to self gravity and operation external force through stable connection with the stator shaft after the lower half bearing is disassembled, the problem that the lower half sealing tile chamber is prone to toppling over is fundamentally solved, and the service life of the lower half bearing chamber is prolonged. And therefore, the safety of dismounting and mounting operation of the sealing tile chamber of the generator is greatly improved.
