Description

Technical Field

[0001] This utility model belongs to the field of tooling components technology, specifically relating to a three-jaw disassembler for a hydraulic turbine pump. Background Technology

[0002] When disassembling a hydraulic turbine pump, the nozzle mechanism needs to be removed from the housing. The housing has three disassembly slots to facilitate nozzle mechanism removal. Without proper tooling, using a flathead screwdriver to pry the nozzle mechanism out from the disassembly slots can easily cause the nozzle mechanism to become misaligned and stuck, or damage to the housing. Therefore, a dedicated three-jaw disassembly tool needs to be designed. Utility Model Content

[0003] This invention provides a three-jaw disassembly tool, offering a convenient, efficient, and safe method for disassembling the nozzle mechanism of a hydraulic turbine pump.

[0004] This utility model provides a three-jaw disassembly tool for a hydraulic turbine pump, comprising a screw, a handle, a sleeve, a bracket, a Y-joint, a ring, and hooks. The bracket has a central opening, and the sleeve is installed in the central opening of the bracket and fixed with screws. The screw is screwed into the threaded hole of the sleeve, and the tail end of the screw passes through the central countersunk hole of the Y-joint. The stepped shaft at the tail end of the screw mates with the inner ring of a bearing and is fixed by a washer and a nut. The bearing is press-fitted into the central countersunk hole of the Y-joint. The handle is inserted into the horizontal through hole at the head of the screw. There are three hooks, each fixed to one of the three ends of the Y-joint by pins. The ring is fitted over the three hooks.

[0005] In this utility model, the bracket is a gate-shaped frame, consisting of a crossbeam and two end legs, with pads fixed to the bottom of the legs.

[0006] In this utility model, the Y-shaped connector is Y-shaped with three non-uniformly distributed ends. The angles between the three ends are 109°, 125°, and 126°, which are consistent with the distribution angles of the three disassembly slots on the hydraulic turbine pump housing.

[0007] In this invention, the inner ring of the circular ring has a 5° inclination angle; the back of the hook claw is provided with a protrusion with a 5° inclination angle.

[0008] The beneficial effects of this invention are as follows: It provides a dedicated three-jaw disassembly tool for the nozzle mechanism of a hydraulic turbine pump, which is convenient, efficient, and safe to use. The bottom pad of the bracket provides protection for the housing; the bearing allows the Y-joint and hook to rotate quickly to the position corresponding to the disassembly groove on the housing; the beveled surface of the ring and the hook securely engages, preventing the hook from loosening and ensuring reliable gripping. This disassembly tool allows the nozzle mechanism to be pulled out vertically without tilting or jamming. Attached Figure Description

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0012] like Figure 1 As shown, a three-jaw disassembly tool for a hydraulic turbine pump includes a screw 1, a handle 2, a sleeve 4, a bracket 5, a Y-joint 6, a ring 7, and hooks 9. The sleeve 4 is installed in the center hole of the bracket 5 and fixed with a screw 3. The screw 1 is screwed into the threaded hole of the sleeve 4, and the tail end of the screw 1 passes through the central countersunk hole of the Y-joint 6. The stepped shaft at the tail end of the screw 1 mates with the inner ring of the bearing 12 and is fixed by a washer 10 and a nut 11. The bearing 12 is press-fitted into the central countersunk hole of the Y-joint 6. The handle 2 is inserted into the horizontal through hole at the head of the screw 1. There are three hooks 9, which are respectively fixed to the three ends of the Y-joint 6 by pins 13. The ring 7 is fitted over the three hooks 9.

[0013] The bracket 5 is a gate-shaped frame, consisting of a crossbeam and two end legs, with pads 8 fixed to the bottom of the legs.

[0014] like Figure 2 As shown, the Y-shaped connector 6 is Y-shaped with non-uniformly distributed three-way ends. The angles between the three ends are 109°, 125°, and 126°, which are consistent with the distribution angles of the three disassembly slots on the hydraulic turbine pump housing.

[0015] The inner ring of the circular ring 7 has a 5° inclination angle; as... Figure 3 As shown, the hook 9 has a protrusion with an inclination angle of 5° on its back. The ring 7 engages with the inclined surface of the hook 9 to secure the hook, making it less likely to loosen and ensuring reliable gripping.

[0016] A bearing 12 is installed at the connection between the screw 1 and the Y-joint 6, which allows the Y-joint 6 and the hook 9 to rotate quickly to the position corresponding to the housing disassembly groove.

[0017] In use, the bracket 5 is supported on the end face of the hydraulic turbine pump housing. Rotate the handle 2 to lower the hook 9 to the same height as the housing disassembly slot. Rotate the Y-shaped connector 6 to align the hook 9 with the three disassembly slots on the housing. Place the hook 9 claw head into the disassembly slot. Lower the ring 7 so that the inner ring of the ring 7 engages with the hook 9 boss to secure the hook 9. Rotate the handle 2 to pull out the nozzle mechanism to complete the disassembly.
