Description

Technical Field

[0001] This utility model relates to the field of pump casing processing technology, specifically a milling machine fixture for producing pump casings. Background Technology

[0002] Pump casings are typically made of materials such as steel, cast iron, stainless steel, and aluminum alloy. These materials have good mechanical properties, corrosion resistance, and wear resistance, which can meet the needs of different working conditions. During the manufacturing process, the pump casing needs to undergo processes such as casting, forging, and welding to ensure its structural integrity and performance stability.

[0003] During the processing of pump casing, the pump casing itself may shake, which often causes the pump casing to shift in position, thus adversely affecting the processing accuracy and effect. In order to ensure the smooth progress of the processing and the stability of the processing quality, a fixture is usually used to hold the pump casing. Since the fixture itself is usually fixed, when it is necessary to adjust the angle of the pump casing to perform processing at a specific angle, the operation process will be relatively complicated and difficult, increasing the processing difficulty and time cost.

[0004] Therefore, a milling machine fixture for producing pump casings is proposed. Utility Model Content

This allows for flexible adjustment of the pump casing processing angle, enabling the pump casing to be processed or tested at different angles, meeting different process requirements. When the lifting frame moves, it drives the connecting frame and gear to move synchronously. The gear slides on the rack, increasing the resistance of the lifting frame movement, making the lifting process more stable and avoiding safety hazards caused by shaking or sudden changes. This makes the pump casing more stable and reliable during processing.

[0019] 2) The moving frame is driven by the cylinder, which in turn drives the two drive rods to move closer to each other.

[0029] The clamping mechanism 6 includes a clamping part and a pressing part.

[0030] The adjustment unit includes a collection hopper 51, the top surface of which is fixedly connected to the placement platform 3. An adjustment frame 52 is provided on the right side of the collection hopper 51. The upper end of the adjustment frame 52 passes through the placement platform 3 and is connected to the bearing of the placement platform 3. A lifting frame 53 is sleeved on the lower end of the adjustment frame 52, and the lower end of the adjustment frame 52 is slidably connected to the inner wall of the lifting frame 53.

[0034] Furthermore, in this embodiment, the hydraulic cylinder 55 is activated, which causes the lifting frame 53 and the adjusting frame 52 to change in height. The adjusting frame 52 causes the right end of the placement platform 3 to rise, causing the placement platform 3 to deflect, thereby changing the deflection angle of the pump housing, which can adjust the processing angle of the pump housing. At the same time, when the lifting frame 53 moves, the lifting frame 53 causes the connecting frame 56 and the gear 59 to move synchronously.

[0035] Furthermore, in this embodiment, by activating the hydraulic cylinder 55, the height of the lifting frame 53 and the adjusting frame 52 can be easily adjusted, thereby changing the deflection angle of the placement platform 3. This allows for flexible adjustment of the pump housing processing angle, enabling the pump housing to be processed or tested at different angles, meeting different process requirements. When the lifting frame 53 moves, it drives the connecting frame 56 and the gear 59 to move synchronously. The gear 59 slides on the rack 510, increasing the resistance to the movement of the lifting frame 53, making the lifting process more stable and avoiding safety hazards caused by shaking or sudden changes. This makes the pump housing more stable and reliable during processing.

At the same time, when the moving frame 65 moves, it drives the pressing plate 67 to move. The pressing plate 67 presses and fixes the upper end of the pump casing.

[0040] Furthermore, in this embodiment, the cylinder 64 drives the moving frame 65 to move, the moving frame 65 drives the two front and rear drive rods 66 to move closer to each other, and the drive rods 66 drive the clamping plate 62 to move synchronously.
