Description

Technical Field

[0001] This utility model relates to the field of hydraulic torque converter pump wheel assembly processing, specifically a pump wheel assembly turret loading tool. Background Technology

[0002] The pump impeller assembly is a crucial component of the torque converter. Connected to the main shaft, the pump impeller transmits the mechanical energy input from the main shaft to the driven shaft via centrifugal force and internal sub-assemblies. Before final assembly of the pump impeller assembly, the thrust surface of its bearings must be machined to ensure extremely high flatness of the bearing surface that mates with the thrust bushing. Insufficient flatness will lead to excessive wear of the thrust bushing, affecting the torque converter's lifespan and reliability.

[0003] The structure of the pump wheel assembly makes it suitable for automated machining on inverted equipment. On such equipment, the workpiece is conveyed to the machining station by a conveyor chain, then a lifting mechanism lifts the workpiece to the final machining station. The machine spindle then picks up the workpiece and performs turning. After machining, the workpiece is returned to its original position, the lifting mechanism descends, and the workpiece flows with the conveyor chain to the next process.

[0004] However, in actual production, the conveyor chain or lifting mechanism may inevitably fail to work properly due to mechanical failures, control abnormalities, or other reasons. If manual clamping is used at this time, it will not only be inefficient, but also difficult to guarantee the relevant dimensions, thus affecting the product processing quality.

[0089] Example 11:

[0090] The main structure of this embodiment is the same as any one of embodiments 1 to 10. Furthermore, the purpose of this utility model patent is to provide a semi-automatic feeding tool for processing pump wheel assemblies on inverted equipment when the conveyor chain or lifting mechanism malfunctions. This feeding tool can be adjusted in both forward and backward directions, and its structure is safe and compact, making it suitable for use under conditions of turret rotation. The working principle of this utility model is as follows:

[0091] The main function of this utility model is to support the workpiece. After the workpiece is placed on the loading tool, the lathe button is pressed manually, and the spindle automatically moves down to grab the workpiece. During the grabbing process, the spindle end face is positioned and contacts the workpiece end face. To ensure that the two are completely in contact, the support part of this loading tool is an elastic support. After contact, the spindle can continue to move down, ensuring that the spindle end face is positioned and the workpiece end face is completely in contact, which can ensure the height dimension between the processing part and the workpiece end face.

[0092] Example 12:

[0093] The main structure of this embodiment is the same as any one of embodiments 1 to 11. Furthermore, the purpose of this utility model is to provide a semi-automatic feeding tool. This feeding tool can be adjusted in both forward and backward directions, and its structure is safe and compact, making it suitable for use in situations where the turret is rotating.

[0094] The features of this utility model are: the mounting base is used to support the workpiece and center it. The mounting base is installed on the support base and is positioned by the boss on one end of the support base. The other end is clearance fit, which allows the mounting base to be adjusted back and forth. The mounting base is designed with a waist-shaped hole and a limit screw hole. After adjustment, it is tightened and limited by two sets of screws, thereby ensuring that the position of the mounting base does not move when the feeding tool is rotated.

[0095] The support base is used to fix the mounting base and move the mounting base up and down together to ensure that the feeding tool or spindle is not damaged due to hard contact.

[0096] The anti-rotation pin is not concentric with the support seat and is used to prevent the support seat from rotating. This prevents the support seat from moving relative to the connecting seat in an angular position during the rotation of the feeding tool, which would cause the spring to jam. If the elastic support function of the feeding tool is lost, the spindle and the feeding tool will make hard contact when the spindle is gripping the part, which may cause damage to the spindle or turret in severe cases.

[0097] The connector is used to center the support base. It also features countersunk holes and spring mounting holes for installing screws and springs. Screw holes are located on the edge of the connector for installing retaining rings.

[0098] The retaining ring is used to limit the support base and prevent it from being thrown out during rotation. When designing the retaining ring, it is necessary to consider whether the retaining ring will interfere with screw III. If it interferes with screw III, the retaining ring structure can be modified according to the actual situation.

[0099] The spring mainly serves to support the mounting base, support base, and parts. The spring force must be greater than the weight of the mounting base, support base, and parts. At the same time, the spring force should not be too large to prevent the parts from being unable to move downwards when the spindle moves down to grab them.

[0100] The base is mounted on the turret and serves to fix the entire feeding tool. The docking structure of the mounting base is designed according to the docking dimensions of the turret. The base is designed with threaded holes for connecting and fixing the connecting base, and stepped holes for fixing the anti-rotation pin.

[0101] Ventilation holes are designed on the connector and base to expel air between the support and connector, ensuring smooth sliding of the mating parts.

[0102] Screw I serves to secure the connector and the base.

[0103] Screw II is used to secure the anti-rotation pin and prevent it from moving up and down.

[0104] Screw V is used to secure the retaining ring.

[0105] Screw III mainly serves as a limit; after the mounting base is adjusted to the correct position, tighten screw III to prevent the mounting base from moving.

[0106] Screw IV serves to tighten the mounting base, preventing it from being thrown out and causing safety hazards when the turret rotates.
