The magnetic abrasive finishing process machine comprises a machine base, a processing box and a rotating magnetic disc, whereinthe machine base comprises a first supporting table and a second supporting table; the processing box is placed on the first supporting table, and the rotating magnetic disc comprises a rotating discand a magnet body; the magnet body is embedded and fixed to the rotating disc, a first motor is installed on the second supporting table, and the rotating disc is fixed to an output shaft of the firstmotor; the processing box comprises a box body and a cover body, a filter plate is arranged in the box body, and the filter plate and the box body are connected through a spring; the filter plate partitions the box body into a processing cavity and a chip removal cavity, a plurality of magnetic abrasives are placed in the processing cavity, and the pore size of filter holes is smaller than the size of the magnetic abrasives; a liquid inlet tube is fixed to the top of the inner wall of the cover body, and a plurality of spray heads are installed on the the liquid inlet tube; a first liquid storage barrel and a second liquid storage barrel are arranged on the sides of the machine base, the first liquid storage barrel is connected with the liquid inlet tube, and the first liquid storage barrel is used for supplying cooling liquid to the liquid inlet tube; and the second liquid storage barrel is connected with the chip removal cavity through a drain tube, and the second liquid storage barrel is used for collecting the cooling liquid and sweeps discharged from the processing box.

The invention relates to a liftable urinal and belongs to the technical field of bathroom sanitary wares. The liftable urinal comprises a first mounting plate used for being mounted on a wall and a second mounting plate used for mounting the urinal, wherein the second mounting plate is slidably arranged on the first mounting plate; a sliding block is arranged on the face, away from the urinal, of the second mounting plate, a first sliding groove for the sliding block to slide is formed in the first mounting plate, and the first sliding groove is in the vertical direction; a first gear is rotationally arranged on the face, away from the urinal, of the first mounting plate, a rack meshed with the first gear is arranged on the second mounting plate, the length direction of the rack is parallel to the length direction of the first sliding groove, and the urinal capable of ascending and descending further comprises a first driving part used for driving the first gear to rotate. The urinal has the effect of widening the use range of the urinal.

The invention discloses a reverse sewing control method, a reverse sewing control system and a sewing machine. The method includes: Step S1: Acquiring the first time period spent by the oscillating plate base to move from the initial position with the initial acceleration to the zero stitch position, and performing Step S2; Step S2: Judging whether the first time period is greater than the preset time length threshold, If so, execute step S3; step S3: adjust the pulling force of the back-tacking electromagnet so that the swing plate base decelerates in the original direction for a second duration, and perform step S4, wherein the back-stitching electromagnet is connected to the swing plate base; step S4: control the swing The plate seat continues to move to the end position according to the original direction, and the acceleration during the movement is not greater than the initial acceleration. This method determines the actual stitch length of the swing plate base by monitoring the movement time of the swing plate base. Compared with the prior art, the generated noise can be reduced.

A method for assembling seal component in seal device of magnetic liquid includes binding bottom pole shoe and un-magnetized R b Fe B as well as top pole shoe together to form seal component, locking prepared seal component on process spindle, grinding external circles two said pole shoes, washing ground seal component, magnetizing washed seal component, placing magnetized seal component in shell internal hole on seal device of magnetic liquid type and injecting magnetic liquid in.

The invention discloses a workpiece carrying device, a workpiece carrying control method and a controller. The workpiece carrying device comprises a motor, an executing mechanism capable of being driven by the motor and the controller connected with the motor. The controller is used for controlling the motor to drive the executing mechanism to carry workpieces; when the controller determines thatcollision exists in the executing mechanism, preset reverse torque is applied to the motor; and the preset reverse torque is opposite to the torque direction when the motor is collided. According to the workpiece carrying device, the workpiece carrying control method and the controller, the workpieces or a carrying tool can be prevented from being damaged during collision when the workpieces are carried.

The invention belongs to the field of chemical engineering, and particularly relates to a pipeline washing device for a chemical heat exchanger. The pipeline washing device comprises a supporting plate, a lifting module, a connecting and disconnecting module, a washing module and a water tank; the lifting module is fixed to the supporting plate, and the lifting module is used for supporting the washing module and driving the washing module to move up and down to wash the inner wall of a pipeline; the washing module is mounted at the lower right end of the lifting module, and the washing module is used for washing the inner wall of the pipeline; the connecting and disconnecting module is mounted on the washing module and used for controlling flow-in and flow-out of waterflow in the washing module; and the water tank is used for supplying water needed by the pipeline washing device. The pipeline washing device repeatedly washes the inner wall and the upper end of the pipeline through joint action of the lifting module, the connecting and disconnecting module and the washing module, and the washing effect is good.
