Abstract
Description
Technical Field
[0001] This utility model belongs to the field of milling machine fixture technology, specifically relating to a milling machine fixture for cutting the keyway of a water pump rotor. Background Technology
[0002] Because common water pump rotors are usually thin at both ends and thick in the middle, and are relatively long, this causes some inconvenience for further machining of the rotor. When milling grooves on water pump rotors, milling machines generally do not have special fixtures. It is difficult to securely fix the rotor on the milling machine worktable with ordinary fixtures. This is very inconvenient during cutting and can easily lead to problems such as instability of the clamping part, resulting in scrapping of the workpiece and causing huge economic and property losses to the enterprise. Utility Model Content
[0003] The purpose of this invention is to address the problem in the prior art where there is no dedicated fixture for milling keyways on water pump rotors, which causes inconvenience in the machining process. This invention provides a milling machine fixture that can stably clamp water pump rotors for easy machining of keyways on water pump rotors.
[0004] Therefore, the present invention adopts the following technical solution:
[0005] A milling machine fixture for milling keyways on a water pump rotor includes a milling machine, a worktable on the milling machine, a support platform mounted on the worktable, a slot for placing the middle part of the water pump rotor formed in the middle of the support platform, a first support groove at one end along the length direction of the support platform, and a second support groove corresponding to the first support groove at the other end, the first support groove and the second support groove having an arc-shaped structure, a hydraulic cylinder bracket fixed on the worktable, the hydraulic cylinder bracket being located near the first support groove, a first hydraulic cylinder mounted on the hydraulic cylinder bracket, the bottom end of the first hydraulic cylinder being directly opposite the first support groove, a second hydraulic cylinder fixed at the end of the worktable near the second support groove, the second hydraulic cylinder being arranged along the length direction of the worktable and directly opposite the second support groove.
[0006] Furthermore, the first hydraulic cylinder is vertically positioned.
[0007] Furthermore, the second hydraulic cylinder is positioned horizontally.
[0008] Furthermore, the bottom end of the first hydraulic cylinder is provided with an elastic protective pad.
[0009] The beneficial effects of this utility model are as follows: a support groove adapted to the rotor is set on the support platform to provide stable support for the rotor. External force is applied to the rotor axis and radial direction by the first hydraulic cylinder and the second hydraulic cylinder, which can effectively clamp the water pump rotor on the support platform of the milling machine worktable to achieve positioning and clamping. The rotor can remain stable during the cutting process, which improves the machining quality of the keyway. It is also convenient to use. Attached Figure Description

[0012] In the figure, 1-milling machine, 2-worktable, 3-support table, 4-slot, 5-first support slot, 6-second support slot, 7-hydraulic cylinder bracket, 8-first hydraulic cylinder, 9-elastic protective pad, 10-second hydraulic cylinder, 11-water pump rotor. Detailed Implementation
[0013] like Figure 1 As shown, a milling machine fixture for milling keyways on a water pump rotor includes a milling machine 1, which can be a conventional horizontal milling machine. The milling machine 1 has a worktable 2, which is an existing component of the milling machine. The worktable 2 is used to mount the milling machine fixture. A support platform 3 is fixed on the worktable 2 for placing the water pump rotor. A slot 4 for placing the middle part of the water pump rotor is formed in the middle of the support platform 3. The length of the slot 4 is the same as the length of the thicker middle part of the water pump rotor. One end of the support platform 3 has a first support groove 5, and the other end has a second support groove 6 corresponding to the first support groove 5. Both the first and second support grooves 5 and 6 are arc-shaped, and their radii are adapted to the radii of the two ends of the water pump rotor. The first and second support grooves 5 and 6 are located on the same straight line and are used to support the two ends of the water pump rotor. A hydraulic cylinder bracket 7 is fixed on the worktable 2, located near the first support groove 5. A vertically arranged... The first hydraulic cylinder 8 and the first hydraulic cylinder 7 are located directly above the first support groove 5. The bottom end of the first hydraulic cylinder 8 is directly opposite the first support groove 5. The first hydraulic cylinder 8 is used to apply downward pressure to the part of the water pump rotor located in the first support groove 5, thereby pressing one end of the water pump rotor tightly into the first support groove 5 to prevent the water pump rotor from rotating and moving in the vertical direction, so as to fix it for easy cutting operation. At the same time, the bottom end of the first hydraulic cylinder 8 is provided with an elastic protective pad 9, which can be made of rubber. The elastic protective pad 9 is used to prevent the bottom end of the first hydraulic cylinder 8 from damaging the surface of the rotor when clamping. The worktable 2 is fixed with a horizontally arranged second hydraulic cylinder 10 near the end of the second support groove 6. The second hydraulic cylinder 10 is arranged along the length of the worktable 2 and is directly opposite the second support groove 6. The second hydraulic cylinder 10 can press against the end of the water pump rotor. The second hydraulic cylinder 10 is used to position the water pump rotor, mainly to limit the displacement of the water pump rotor in the direction perpendicular to the milling machine spindle (i.e., displacement along the length of the worktable 2), to prevent the workpiece from being scrapped during milling.
[0014] When this utility model is used (e.g.) Figure 2 As shown, the thinner ends of the water pump rotor 11 are placed in the first support groove 5 and the second support groove 6 at both ends of the support platform 3, and the thicker part of the middle of the water pump rotor 11 is placed in the slot 4 in the middle of the support platform 3. The first hydraulic cylinder 8 is activated, and the first hydraulic cylinder 8 presses the water pump rotor 11 tightly in the first support groove 5 so that it cannot rotate. Then the second hydraulic cylinder 10 is activated to apply external force to one end of the water pump rotor 11 in the horizontal direction, so that the thicker part of the middle of the water pump rotor 11 is pressed against the lower part of the first support groove 5, restricting the displacement of the water pump rotor 11 in the length direction of the worktable 2. Finally, the water pump rotor 11 is positioned and tightened to facilitate the cutting of the keyway. After the clamping is completed, the parts of the water pump rotor 11 that need to be milled can be milled.
