Description

Technical Field

[0001] The invention relates to the technical field of electronic water pumps, and in particular to a batch grooving tool for processing automobile electronic water pump bushings and a use method thereof. Background Art

[0002] The impeller in the automotive electronic water pump generally rotates under the drive of the rotating shaft, and a bushing is usually arranged at the shaft hole where the rotating shaft is installed, so that the shaft hole has good anti-wear performance. During long-term use, the bushing is easy to produce a gap with the shaft hole, causing relative sliding, which affects the work efficiency. In order to improve the friction between the bushing and the shaft hole of the impeller, people usually set a slot on the side of the bushing so that the slot on the bushing is clamped in the corresponding protruding part of the shaft hole. However, when processing the slot on the outer surface of the bushing, it is difficult to clamp the bushing, and one bushing is processed each time, and the processing efficiency is low. A bushing slot cutting device disclosed in publication number CN105127804A includes a base plate, a clamping device is arranged on the front side of the base plate, and a cutting device is arranged on the rear side of the base plate. The cutting device includes a slideway arranged on the base plate, a sliding frame arranged in the slideway, a threaded rod arranged on the front side of the sliding frame by a threaded connection, a cylinder installed on the upper part of the sliding frame, a mounting plate installed on the shaft of the cylinder, a motor installed on the mounting plate, and a cutting blade installed on the shaft of the motor. The bushings on the main rod are uniformly compressed by the left and right clamping plates, and the clamped bushings are uniformly cut by the cutting device, which greatly improves the processing efficiency and helps to ensure the uniformity of processing quality. However, the above device has some defects in actual use: the bushings to be slotted are stacked on each other, and the force generated when the bushing being processed is cut will act on the bushing that is in contact with it, affecting the bushing being processed and the cutting mechanism, which is easy to cause the bushing and the cutting mechanism to be scrapped. Summary of the invention

[0003] In order to solve the above technical problems, the present invention proposes a batch grooving tool and a use method for processing automotive electronic water pump bushings.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0005] A batch grooving tool for processing automotive electronic water pump bushings, including two relatively distributed lateral support plates, a fixed placement clamping plate with two ends fixedly connected to the two lateral support plates, a movable placement clamping plate with two ends slidably connected to the two lateral support plates, and a bushing support shaft passing through the two lateral support plates, and locking assemblies that cooperate with the bushing support shaft are arranged on the two lateral support plates, and the fixed placement clamping plate and the movable placement clamping plate are symmetrically distributed with the axis on the bushing support shaft as the symmetry axis.

[0006] A method for using a batch grooving tool for processing an automotive electronic water pump bushing is applied to the batch grooving tool for processing an automotive electronic water pump bushing, comprising the following steps:

[0007] Step 1: Turn the four locking rods in sequence to remove them from the locking holes on the bushing support shaft, and then pull the bushing support shaft out of the two lateral support plates;

[0008] Step 2: Unscrew the limit bolt and remove the movable placement splint;

[0009] Step 3: Place the bushing to be slotted vertically in the placement slot on the fixed placement clamp plate, then install the movable placement clamp plate into the installation slide again, align the placement slot on the movable placement clamp plate with the bushing, and screw in the limit bolt again to complete the clamping of the bushing;

[0010] Step 4: Insert the bushing support shaft through the insertion hole on the lateral support plate on one side, pass through the clamped bushings in sequence, and pass out from the insertion hole on the lateral support plate on the other side;

[0011] Step 5: Screw the locking rod into the locking hole again to complete the locking and fixing of the bushing support shaft;

[0012] Step 6: Place the tool on the wire cutting equipment, and flip it forward or backward 90° before placing it;

[0013] Step 7: Synchronously slot several bushings on the tooling. After the slotting is completed, repeat the first step to the second step and remove the bushings that have been slotted.

[0014] The beneficial effects of the present invention are:

[0015] The present invention provides a batch grooving tool for processing automotive electronic water pump bushings. By arranging a plurality of equally spaced placement partitions, namely placement slots, a plurality of bushings to be grooved are separated, thereby avoiding the problem that, during the grooving process, the force generated when the bushing currently being processed is cut will act on the bushing that is in contact with it, thereby affecting the bushing currently being processed and the cutting mechanism, and easily causing the bushing and the cutting mechanism to be scrapped.
