Description

Technical Field

[0001] The utility model relates to the technical field of automobile impellers, in particular to a swing correction device for automobile water pump impellers. Background Art

[0002] Referring to the patent document with application number "CN202320398811.6" and named "Automobile Water Pump Impeller Swing Correction Device", this patent document includes a bracket, a support plate, a drive shaft and a drive device. The support plate is fixedly installed on the upper end of the bracket, and the drive shaft is installed on the support plate through the drive device. The drive device is used to rotate the drive shaft, and the drive shaft is used to connect with the impeller; it also includes an electric push rod, a mounting block, a marking pen and an eccentricity detection device. The eccentricity detection device is installed on the support plate. The eccentricity detection device has the function of eccentricity detection, and the electric push rod is installed on the eccentricity detection device.

[0003] The prior art determines whether the current impeller has uneven gravity by the up and down jumping reaction of the pointer. The pointer of the prior art reacts by the jumping of the roller, and makes corresponding designations on the support frame to facilitate staff to find that although the pointer can produce higher sensitivity after the roller jumps, the long-term jumping of the pointer will cause distance or loss from the support frame, resulting in the pointer failing to react to the support frame after the roller jumps, thereby causing the staff to miss the observation and reducing the detection efficiency of the impeller.

[0004] Therefore, we designed a device for correcting the swing of the impeller of an automobile water pump. Utility Model Content

[0005] The utility model aims to solve the problem that the prior art suffers from wear and tear after long-term use, resulting in the inability of staff to capture information in time, and thus proposes a vehicle water pump impeller swing correction device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A car water pump impeller swing correction device comprises a housing and an impeller, wherein the housing is provided with a motor for rotating the impeller, the motor is provided with a supporting steel frame, the motor is fixedly connected to the impeller via an auxiliary shaft, and is characterized in that the supporting steel frame is provided with a transmission body, the transmission body is provided with a compression elastic shaft for sensing force, the transmission body is provided with a transmission shaft for transmitting force, the transmission shaft is provided with a sensor plate for collecting data, and the transmission body is provided with a pulley for detecting the impeller.

[0008] Preferably, a through groove is provided on the transmission body, and the transmission body is fixedly connected to the supporting steel frame.

[0009] Preferably, a circular hole is provided on the transmission body, and the compression elastic shaft is matched with the circular hole, and a plurality of connecting shafts for improving the force transmission performance are provided on the transmission body.

[0010] Preferably, the transmission shaft is symmetrically arranged on the top of the transmission body, the transmission shaft is fixedly connected to the compression elastic shaft, and a trigger shaft is arranged on the side wall of the transmission shaft.

[0011] Preferably, the supporting steel frame is fixedly connected to the sensor plate via a fastener, a slide groove is provided on the sensor plate, and the trigger shaft is adapted to the slide groove.

[0012] Preferably, a sliding shaft is provided on the transmission body, the sliding shaft is fixedly connected to the compression elastic shaft, the sliding shaft is fixedly connected to the pulley via a fixed shaft, and the pulley is against the impeller.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model arranges the compression spring shaft and the transmission shaft so that the pulley can sense the weight change of the impeller and transmit the force to the compression spring shaft in time, thereby improving the floating effect of the transmission shaft and prompting the trigger shaft to produce corresponding actions on the sensor plate, which is convenient for the staff to capture information in time. The floating distance of the trigger shaft can be increased through the slide groove to avoid excessive difference in the impeller weight, which causes the trigger shaft to separate from the sensor plate, thereby improving the efficiency of impeller detection.

[0015] 2. The utility model reduces the large extrusion force when the transmission body is subjected to a strong and erroneous force through the setting of the connecting shaft, thereby maintaining the normal operation of the transmission body. At the same time, the compression elastic shaft can effectively absorb the large force, reduce the damage of the extrusion force to the transmission body, and transmit the force to the transmission shaft to make the trigger shaft slide to the top of the slide groove, so that the staff can respond in time to adjust and replace the impeller.

The transmission body 5 is provided with a plurality of connecting shafts 52 for improving the force transmission performance. The connecting shafts 52 allow the transmission body 5 to achieve a small degree of contraction to avoid problems such as the placement of the impeller 4, which leads to excessive force and affects the force transmission effect of the transmission body 5.

[0027] A transmission shaft 53 for transmitting force is provided on the transmission body 5. The transmission shaft 53 is used to collect the force value and float up and down following the force of the compression elastic shaft 51.

The pulley 542 is against the impeller 4, and the pulley 542 is against the cylindrical surface of the impeller 4.

[0030] The working principle of the utility model is as follows: first, place the pulley 542 on the cylindrical surface at one end of the impeller 4, then start the motor 2 to rotate the impeller 4, and according to the ups and downs of the cylindrical surface, the ups and downs will be transmitted to the compression elastic shaft 51, and the compression elastic shaft 51 will transmit the force to the transmission shaft 53 by stretching, and then the trigger shaft 531 will slide on the sensor plate 532, and the staff's electronic equipment will receive the force information transmitted by the sensor plate 532.
