Description

Technical Field

[0001] This application relates to the field of motor manufacturing tooling technology, and more specifically, to a rotatable, variable-position motor flange end cap processing device. Background Technology

[0002] The motor flange end cover, located at the end of the motor, is an important component used to fix and support the motor shaft and ensure the internal sealing of the motor, preventing dust and other impurities from entering. The motor flange end cover is generally disc-shaped, and its manufacturing process mainly involves machining its external shape, bearing housing, and hole positions.

[0003] like Figure 1 The workpiece 8 shown is one of the commonly used motor flange end caps. Both the upper and lower end faces of workpiece 8 require hole machining. The upper end face needs to be machined with I-shaped holes, and the lower end face needs to be machined with circular holes. Since I-shaped holes cannot be drilled, the I-shaped holes of workpiece 8 can only be machined on a machining center or milling machine. When the pitch circle of the I-shaped hole is larger than the machine tool's travel range, it can only be machined on a machine tool with a corresponding machining travel range. Whether workpiece 8 can be machined depends on the machine tool's machining travel range, which places high demands on the machine tool's travel range, results in low utilization of existing machine tools, and leads to high equipment costs in production. In addition, changing machine tools for machining cannot guarantee consistent machining accuracy.

[0004] Therefore, there is an urgent need for a motor flange end cap processing device to solve the problem of the motor flange end cap exceeding the machine tool travel range during processing. Utility Model Content

[0005] To solve the aforementioned problems, the present invention provides a rotatable, variable-position motor flange end cover processing device, which solves the problems of limited processing stroke and inconsistent processing accuracy of existing motor flange end covers during processing. The device includes a worktable and a fixture mounted on the worktable. The worktable has a T-slot, and the bottom of the fixture has at least two limiting holes. Each limiting hole has a connector that mates with the T-slot. The fixture is mounted on the worktable via multiple connectors. The edge of the fixture has positioning holes, and positioning pins are detachably connected to the positioning holes.

[0006] Preferably, the workpiece is mounted on the fixture, and the bottom end of the workpiece is provided with multiple indexing holes that cooperate with the positioning pins.

[0007] Preferably, the bottom end of the workpiece is provided with an annular boss, and the top end of the fixture is provided with an inner stop, with the annular boss and the inner stop being in clearance fit.

[0008] Preferably, the connector includes a screw and a T-block, the T-block being threaded to the end of the screw, and the T-block matching the shape of the T-slot.

[0009] Preferably, the bottom end of the fixture is provided with a keyway, and a positioning key is connected in the keyway, the cross-sectional width of which matches the width of the T-slot.

[0010] Preferably, the keyway and the multiple limiting holes are distributed on the same straight line.

[0011] Preferably, the multiple limiting holes are distributed on the same straight line passing through the center of the fixture.

[0012] Preferably, the fixture is further provided with a pressure plate for pressing the workpiece during processing.

[0013] The beneficial effects of this utility model are as follows: the edge of the fixture is provided with positioning holes, and the bottom end of the workpiece is provided with multiple indexing holes that cooperate with the positioning pins. With the cooperation of the positioning pins and the indexing holes, the workpiece can rotate and change its position, enabling the machining of I-type holes on machine tools with small machining stroke ranges, thus expanding the applicable range of the machine tool. Whether the workpiece can be machined is not limited by the machining stroke of the machine tool, improving the utilization rate of existing machine tools and reducing the equipment cost of production and manufacturing. The same machine tool is always used for machining, ensuring the machining accuracy and positional accuracy of the I-type holes. The device has a simple structure, is easy to operate, has low production cost, and is easy to promote and apply on a large scale. Attached Figure Description

[0023] The present application will now describe a rotatable, variable-position motor flange end cap processing device provided in the embodiments of this application.

[0024] Please see Figures 1 to 4 The diagram below illustrates the structure of this utility model. The rotatable variable-position motor flange end cap processing device includes a worktable 1 and a fixture 2 mounted on the worktable 1. The worktable 1 has a T-slot 3, and the bottom end of the fixture 2 has at least two limiting holes 4. Each limiting hole 4 contains a connector 5 that mates with the T-slot 3. The fixture 2 is mounted on the worktable 1 via multiple connectors 5. The edge of the fixture 2 has positioning holes 6, and positioning pins 7 are detachably connected to the positioning holes 6. In this embodiment, there are two limiting holes 4 and two connectors 5. The fixture 2 is securely mounted on the worktable 1 by the two connectors 5 engaging with the two limiting holes 4 respectively.

[0025] Specifically, a workpiece 8 is mounted on the fixture 2. The bottom end of the workpiece 8 has multiple indexing holes 801 that mate with the positioning pins 7. The workpiece 8 is inserted into the indexing holes 801 and the positioning holes 6 of the fixture 2 through the positioning pins 7, and is detachably mounted on the fixture 2. In this embodiment, the upper and lower end faces of the workpiece 8 need to be machined with holes. The upper end face needs to be machined with I-shaped holes, and the lower end face has already been machined with circular indexing holes 801. With the cooperation of the locating pin 7 and the indexing hole 801, the workpiece 8 can rotate and change its position. After machining the I-type hole that can be machined within the machine tool's stroke range, the operator pulls out the locating pin 7, rotates the workpiece 8, aligns the next indexing hole 801 on the workpiece 8 with the locating hole 6 on the fixture 2, inserts the locating pin 7 again, and continues to machine the I-type hole, thus completing the change of the workpiece 8's position. This allows the machining of I-type holes to be completed on machine tools with a small machining stroke range, expanding the machine tool's applicability. Whether the workpiece 8 can be machined is not limited by the machine tool's machining stroke, improving the utilization rate of existing machine tools and reducing the equipment cost of production and manufacturing. Using the same machine tool for machining always ensures the machining accuracy and positional accuracy of the I-type hole.

[0026] Furthermore, the bottom end of the workpiece 8 is provided with an annular boss 9, and the top end of the fixture 2 is provided with an inner stop 10. The annular boss 9 and the inner stop 10 are in clearance fit. The workpiece 8 is in a relatively stable position during processing, which improves the processing accuracy; it is also easier for the operator to align the workpiece 8, making the operation more convenient.

[0027] Specifically, the connector 5 includes a screw 501 and a T-block 502. The T-block 502 is threaded to the end of the screw 501. The T-block 502 matches the shape of the T-slot 3. The connector 5 achieves a fixed connection between the clamp 2 and the worktable 1. This connection method is stable and reliable.

[0028] Furthermore, the bottom end of the fixture 2 is provided with a keyway, and a positioning key 11 is connected in the keyway. The cross-sectional width of the positioning key 11 matches the width of the T-slot 3 to ensure consistent positioning when the fixture 2 is repeatedly installed on the worktable 1. Specifically, in this embodiment, the positioning key 11 is installed into the keyway by screws 501.

[0029] Furthermore, the keyway and multiple limiting holes 4 are distributed on the same straight line.

[0030] Furthermore, multiple limiting holes 4 are distributed on the same straight line passing through the center of the clamp 2.

[0031] Specifically, the fixture 2 is also equipped with a pressure plate for pressing down the workpiece 8 during processing.

[0032] The method of using this utility model is as follows: When in use, the positioning key 11 is fixed to the keyway at the bottom of the fixture 2 by screw 501, and the fixture 2 is installed on the worktable 1 by connecting piece 5; one of the indexing holes 801 of the workpiece 8 to be processed is aligned with the positioning hole 6 on the fixture 2, the positioning pin 7 is inserted to fix the workpiece 8 on the fixture 2, and the workpiece 8 is pressed with a pressure plate to perform I-type hole milling; after processing the I-type holes that can be processed within the machine tool's travel range, the operator releases the pressure plate pressing the workpiece 8, pulls out the positioning pin 7, rotates the workpiece 8 so that the next indexing hole 801 on the workpiece 8 is aligned with the positioning hole 6 on the fixture 2, then inserts the positioning pin 7 again, presses the workpiece 8 with a pressure plate, and continues to process the I-type holes, completing the change of the workpiece 8's position until all the I-type holes are processed, then the pressure plate is released and the finished workpiece 8 is taken out.

[0033] In this utility model, the edge of the fixture 2 is provided with positioning holes 6, and the bottom end of the workpiece 8 is provided with multiple indexing holes 801 that cooperate with the positioning pins 7. With the cooperation of the positioning pins 7 and the indexing holes 801, the workpiece 8 can rotate and change its position, and can complete the processing of I-type holes on machine tools with small processing stroke range, thus expanding the applicable range of machine tools. Whether the workpiece 8 can be processed is not limited by the processing stroke of the machine tool, improving the utilization rate of existing machine tools and reducing the equipment cost of production and manufacturing. The same machine tool is always used for processing, ensuring the processing accuracy and position of the I-type holes. The device has a simple structure, is easy to operate, has low production cost, and is easy to promote and apply on a large scale.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
