Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling, in particular to a positioning tooling for machining the end face of a rotor side cover. Background Art

[0002] When machining the end face of a rotor side cover, a positioning fixture is required. The positioning fixture mainly fixes the end face of the rotor side cover to facilitate the machining of the workpiece on the end face of the rotor side cover. The existing positioning fixture and the end face of the rotor side cover are fixed by a point contact method. This fixing method has insufficient fixing strength, and the end face of the rotor side cover is extremely easy to deform during the machining process, and the situation of tool deflection will also occur, that is, the end face of the rotor side cover deviates to a certain extent from the positioning fixture in the direction away from the machining workpiece, resulting in the non-compliance of the finished product of the end face of the rotor side cover and being unable to meet the process requirements. Summary of the Utility Model

[0008] And a pressing block and a clamping block;

[0009] The clamping block is arranged in the cavity of the fixture body. When the rotor side cover is placed in the cavity, the clamping block can be abutted against the outer side wall of the rotor side cover through a screw on the fixture body;

[0010] The pressing block is arranged on the end face of the fixture body. When the rotor side cover is placed in the cavity, the pressing block can press against one end face of the rotor side cover.

[0011] Preferably, it further includes a reference block, which is located between the fixture body and the pressing block and is threadedly connected to the pressing block.

[0017] Preferably, the number of the pressing blocks is at least two.

[0018] Preferably, the rotor side cover and the fixture main body are fixed by internal hexagonal screws.

[0019] Preferably, the number of the pressing blocks is at least two.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] In the present utility model, on the basis that the rotor side cover and the fixture main body are in point contact and fixed by internal hexagonal screws, the rotor side cover and the fixture main body are first clamped through the pressing block; the rotor side cover and the fixture main body are clamped again by fixing one end of the pressing block on the end face of the fixture main body and abutting the other end against the end face of the rotor side cover; compared with the existing method of solely using internal hexagonal screws for point contact fixation, the stability of the rotor side cover in the fixture main body is greatly improved, the situations of deformation and tool deflection of the rotor side cover during the machining process are avoided, the position balance is maintained, and the problems in the current prior art are solved.

[0037] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0038] As Figures 1-6 shown, the embodiments of the present utility model provide a positioning tooling for machining the end face of a rotor side cover, including: a fixture main body 1, a pressing block 2, a clamping block 3, a reference block 5, etc.

[0039] Among them, the fixture main body 1 has a cavity 13 that is adapted to the outer shape of the rotor side cover 4 and runs through from front to back. The fixture main body 1 is used to fix the rotor side cover 4; the pressing block 2 is arranged in the cavity 13 of the fixture main body 1. When the rotor side cover 4 is placed in the cavity 13, the pressing block 2 can abut against the outer side wall of the rotor side cover 4 through the screws on the fixture main body; the clamping block 3 is arranged on the end face of the fixture main body 1. When the rotor side cover is placed in the cavity 13, the clamping block 3 can press against one end face of the rotor side cover 4.

[0040] Specifically, as Figure 3 shown, at least two first threaded holes 11 are penetrated and opened on the outer side wall of the fixture main body 1, and at least two second threaded holes 12 are opened on its end face.

[0041] As Figure 3 and Figure 4 shown, the pressing block 2 is located between the fixture main body 1 and the rotor side cover 4, and the number of the pressing blocks 2 is at least two. The shape of the pressing block 2 is adapted to the outer side wall of the rotor side cover 4, that is, the pressing block 2 can completely fit on the outer side wall of the rotor side cover 4; several blind holes 21 are opened on the pressing block 2, and the screws penetrate through the first threaded holes 11 and abut against the blind holes 21 to realize the pressing of the pressing block 2 against the outer side wall of the rotor side cover 4; the pressing block 2 improves the stability of the rotor side cover 4 and avoids the deformation of the rotor side cover 4 during machining. Preferably, in this embodiment, the number of the pressing blocks 2 is two. The pressing block 2 is made of metal steel.

[0042] As Figure 6 shown, in order to further improve the pressing force of the clamping block 3 on the rotor side cover 4, a reference block 5 is arranged between the fixture main body 1 and the clamping block 3. Specifically, the reference block 5 is a block-shaped component with a taper, and the number of the reference blocks 5 is at least two. The shape of the reference block 5 is adapted to the end face of the fixture main body 1. A threaded hole (not shown in the figure) is penetrated and opened on the reference block 5, and the threaded hole corresponds to the second threaded hole 12. The reference block 5 can be fixedly connected to the end face of the fixture main body 1 through the threaded hole. Preferably, in this embodiment, the number of the reference blocks 5 is four, and they are respectively fixedly connected to the clamping block 3 through threads.

[0043] As Figure 5As shown, a through hole 31 is formed through the pressing block 3, and the through hole 31 corresponds to the threaded hole and the second threaded hole 12 on the reference block 5; the number of pressing blocks 3 is at least two. As Figure 6 shown, one end of the pressing block 3 is fixedly arranged on the end face of the fixture body 1 through the reference block 5, and the other end abuts against the end face of the rotor side cover 4, so as to realize the further clamping operation of the pressing block 3 on the rotor side cover 4. The pressing block 3 improves the stability of the rotor side cover 4, avoids the situation of tool deflection during the processing of the rotor side cover 4, and maintains the position balance. As Figure 1 shown, in this embodiment, there are 4 pressing blocks 3, which are respectively arranged on the end face of the fixture body 1 far from the workpiece to be processed; the pressing block 3 is made of metal steel.

[0044] During the specific operation, first place the rotor side cover 4 in the cavity 13 of the fixture body 1, align the threaded hole on the rotor side cover 4 with the threaded hole at the bottom of the fixture body 1, and then use an internal hexagon screw to realize the positioning of the rotor side cover 4 and the fixation between the rotor side cover 4 and the fixture body 1. Then place the abutting block 2 on the outer side wall of the rotor side cover 4, and gradually tighten the screw so that the screw penetrates through the first threaded hole 11 until the screw abuts against the blind hole 21. At this time, the rotor side cover 4 and the fixture body 1 are first clamped through the abutting block 2; then place the pressing block 3 and the reference block 5 on the end face of the fixture body 1, make the reference block 5 fit with the end face of the fixture body 1, and when the through hole 31 on the pressing block 3 corresponds to the threaded hole and the second threaded hole 12 on the reference block 5, fix them through an internal hexagon screw, so that one end of the pressing block 3 is fixed on the end face of the fixture body 1 through the reference block 5, and the other end abuts against the end face of the rotor side cover 4, and finally realize the re-clamping of the rotor side cover 4 and the fixture body 1.
