Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing process equipment, and specifically relates to a dual-station electronic pump casing drilling and milling integrated fixture. Background Technology

[0002] Electric pumps are a crucial component in new energy vehicles, with high demand and large-scale processing. They require extremely high precision, especially the pump housing, which involves numerous machining steps. Early pump housing machining fixtures used manual clamping, with drilling and milling processes separated. Each process required one fixture and one machine tool. One production line needed two machining centers and two operators; two production lines required four machine tools, four machining centers, and four operators. Multiple clamping operations were necessary to complete the entire machining process. This reliance on multiple machine tools and operators, along with repeated clamping, resulted in excessively high processing costs, low production efficiency, and a high risk of damage during clamping, compromising product quality. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a dual-station electronic pump housing drilling and milling integrated fixture with simple structure, high production efficiency, and guaranteed processing quality.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: a dual-station electronic pump housing drilling and milling integrated fixture includes a base plate, characterized in that: an oil passage block is provided on the right edge of the base plate, and an oil port one and an oil port two are provided on the oil passage block; a first process station one and a first process station two are arranged side by side at the front of the base plate; the fixture structures set on the first process station one and the first process station two are the same, that is, a support plate is provided on each of the first process station one and the first process station two; a centering shaft one is provided at the center of the support plate; the support plate is a polygonal column; two corresponding hydraulic lever cylinders are provided on opposite sides; lever cylinder pressure plates are provided on the hydraulic lever cylinders; and an outline limiting post is provided on one side of the support plate. An elastic lateral locking post is provided on the side of the support plate corresponding to the outer shape limiting post. A reference sleeve is provided on the bottom plate at the corner between the outer support plate and the hydraulic lever cylinder. An anti-misalignment rod is provided on the support plate adjacent to the outer shape limiting post. Two inclined support plates are provided on the rear side of the bottom plate. A second process station one and a second process station two are provided on the two inclined support plates. The fixture structure provided on the second process station one and the second process station two is the same, that is, a support sleeve is provided on the inclined surface of the inclined support plate. A centering shaft two is provided at the center of the support sleeve. A limiting pin and an anti-misalignment rod two are provided on the outside of the support sleeve. A hydraulic corner cylinder is provided on the other side of the limiting pin. A corner cylinder pressure plate is provided on the hydraulic corner cylinder.

[0005] The beneficial effects of this utility model are: the dual-station electronic pump housing drilling and milling integrated fixture changes manual clamping to hydraulic automatic clamping, and improves the existing two production lines, four machine tools and four machining centers to two production lines, one machine tool and one machining center. The oil circuit is set in the base plate, so there are no connecting pipelines between the hydraulic cylinders, thereby saving manpower, reducing costs, and greatly improving production efficiency. At the same time, it reduces the number of clamping times, reduces the collisions caused by clamping, and ensures product quality. Attached Figure Description

Detailed Implementation

[0010] Example, see attached document Figures 1-3The dual-station electronic pump housing drilling and milling integrated fixture has an oil passage block 4 on the right side of the base plate 1. Oil port 4-1 and oil port 4-2 are located on the side of the oil passage block 4. First process station 1-1 and first process station 2-2 are arranged side-by-side at the front of the base plate 1. The fixture structures on first process station 1-1 and first process station 2-2 are identical, namely, each first process station 1-1 and first process station 2-2 is equipped with a support plate 2. A centering shaft 7 is located at the center of the support plate 2, and the periphery of the support plate 2 is... The device is hexagonal in shape, with two corresponding hydraulic lever cylinders 9 on the left and right sides. Each hydraulic lever cylinder 9 has a lever cylinder pressure plate 18. An outline limiting post 8 is provided on the support plate 2 adjacent to the rear side of the left hydraulic lever cylinder 9. An elastic lateral locking post 6 is provided on the left support plate 2 of the right hydraulic lever cylinder 9. A reference sleeve 5 is provided on the bottom plate 1 at the corner between the support plate 2 and the hydraulic lever cylinder 9. An anti-misalignment rod 10 is provided on the support plate 2 adjacent to the outline limiting post 8 to prevent the workpiece 17 from being installed in the wrong direction. Two inclined support plates 3 are arranged side by side at the rear of the base plate 1. A second process station 3-1 and a second process station 3-2 are provided on the two inclined support plates 3. The fixture structures provided on the second process station 3-1 and the second process station 3-2 are the same, that is, a support sleeve 15 is provided on the right side of the inclined support plate 3, a centering shaft 16 is provided at the center of the support sleeve 15, an anti-misalignment rod 11 is provided at the front end of the support sleeve 15, a hydraulic angle cylinder 13 is provided on the left side of the inclined support plate 3, an angle cylinder pressure plate 12 is provided on the hydraulic angle cylinder 13, and a limit pin 14 is provided between the upper left part of the support sleeve 15 and the hydraulic angle cylinder 13.

[0011] The dual-station electronic pump housing drilling and milling integrated fixture consists of two processes, as follows: In the first process, the workpiece 17A is placed with its surface facing the support plate 2. During the installation of the workpiece 17, the anti-misalignment rod 10 ensures the clamping direction of the workpiece 17. The workpiece 17 is rotated so that the first-order outer shape limit point 17-4 of the workpiece 17 is tightly against the outer shape limit post 8 on the support plate 2. The first and second order centering holes 17-1 are inserted into the centering shaft 7. The other side of the outer shape is clamped by the elastic side clamp (the elastic side clamp has a cylindrical top that can swing, and due to the built-in spring, it can generate a lateral reset force). Oil is introduced into the oil port 4-1. The lever cylinder pressure plate 18 is activated to press the edge of the second order limit hole 17-3 of the workpiece 17. Then, threaded bottom holes, tapping, drilling, milling of planes, and second order limit holes can be processed. After processing is completed, oil is introduced into the oil port 4-2, the lever cylinder pressure plate 18 is released, and the workpiece is unloaded, thus completing the first process. In step two, workpiece 17A is lowered with its surface facing the support sleeve 15. Anti-misalignment rod 11 ensures the clamping direction of workpiece 17. Limit pin 14 is inserted into the second-order limiting hole 17-3. Centering shaft 16 is inserted into the first and second-order centering holes 17-1. Oil is introduced through port 4-1. The angle cylinder pressure plate 12 is activated to press the B surface of workpiece 17. The oblique hole 17-2 on the B surface is drilled and milled. After machining, oil is introduced through port 4-2. The angle cylinder pressure plate 12 is activated to release the workpiece, completing step two. All of the above steps can be repeated.
