[0001] The present application relates to the technical field of metal processing equipment, and in particular to a processing fixture and a CNC machine tool for a pump housing. Background Art

[0002] At present, the application of CNC machine tools is becoming more and more popular. In the process of realizing automated processing, CNC machine tools, in addition to CNC systems and core functional components, also need to be equipped with processing fixtures for pump shells to assist in the processing of the entire machine.

[0003] However, most of the existing pump casing processing fixtures use bolts and other structures to connect the fixture to the pump casing. Usually, the processing personnel are required to manually use bolts to connect the fixture and the pump casing, and manually tighten the bolts to achieve the connection between the fixture and the pump casing. The process of manually tightening the bolts is not only time-consuming and labor-intensive, but also easily causes the fixture to be unreliable due to improper operation. Summary of the invention

[0004] In order to improve the problem that the existing processing fixture needs to use bolts and other structures to manually fix the pump body shell, the present application provides a processing fixture and a CNC machine tool for the pump body shell.

[0005] In the first aspect, the present application provides a pump housing processing fixture that adopts the following technical solution: A processing fixture for a pump housing, comprising: The placement seat is provided with a groove portion, and the groove portion is used to place the pump casing; The rotating seat is fixedly connected to the placement seat, and the movable end of the rotating seat rotates around the central axis of the rotating seat to drive the placement seat to rotate around the axis.

[0006] By adopting the above technical solution, the placement seat can provide stable support and positioning for the pump shell, and the groove part can match the shape of the pump shell, so as to ensure that the pump shell can be accurately placed in the predetermined position during the processing, and improve the problem that the existing processing fixture needs to use bolts and other structures to manually fix the pump shell; the rotating seat can rotate around the central axis, thereby driving the placement seat and the pump shell placed thereon to rotate around the axis, adjusting the angle and position of the pump shell, and improving the flexibility and efficiency of processing; the placement seat can provide stable support and positioning for the pump shell, and this stable support and precise positioning are key factors to ensure the smooth progress of the processing process. The groove part on the placement seat can match the shape of the pump shell, and this matching enables the pump shell to be accurately placed in the predetermined position during the processing, thereby ensuring the accuracy and efficiency of the processing. This design effectively improves the problem that the existing processing fixture needs to use bolts and other structures to manually fix the pump shell, avoiding the time waste and potential unreliable fixation caused by manual fixation. At the same time, the rotating seat can rotate around the central axis, and this rotation function enables the placement seat and the pump shell placed thereon to rotate flexibly around the axis, so that it is convenient for the staff to adjust the angle and position of the pump shell according to the processing requirements. This adjustability not only improves processing flexibility, but also significantly improves processing efficiency, making the entire processing process smoother and more efficient.

[0007] Preferably, the groove portion has a V-shaped structure and forms a first side wall and a second side wall, and the first side wall and the second side wall are perpendicular to each other.

[0008] By adopting the above technical solution, the V-shaped groove can fit closely with the shape of the pump casing, so that the pump casing can be constrained and supported from two mutually perpendicular directions. The pump casing can be automatically centered when placed in the groove, reducing the steps and time of manual adjustment, improving the clamping efficiency, and dispersing the forces generated during the processing; the V-shaped groove can fit closely with the shape of the pump casing. This tightly fitting structural design enables the V-shaped groove to effectively constrain and support the pump casing from two mutually perpendicular directions. When the pump casing is placed in the groove, due to the geometric characteristics of the V shape, the pump casing can be automatically centered without the need for tedious manual position adjustment, thereby significantly reducing the steps and time of manual adjustment. This feature not only improves the clamping efficiency, but also ensures the stability of the pump casing during the processing through the automatic centering function. At the same time, the design of the V-shaped groove can also disperse the forces generated during the processing, avoiding deformation or damage of the pump casing due to concentrated force, thereby further improving the processing quality and the service life of the equipment.

[0009] Preferably, the angles between the first side wall and the second side wall of the groove portion and the ground are both 45°.

[0010] By adopting the above technical solution, the 45° angle design enables the two end faces of the pump housing to be opposite to the processing component at the same angle after the rotating seat rotates, which simplifies the angle adjustment steps in the processing process and avoids the errors and time waste caused by manual angle adjustment in traditional fixtures; the 45° angle design enables the two end faces of the pump housing to be opposite to the processing component at the same angle after the rotating seat rotates.

However, this manual adjustment is not only time-consuming, but also prone to human errors, resulting in unstable processing accuracy. After adopting the 45° angle design, the two end faces of the pump housing can automatically align to the appropriate angle when the rotating seat rotates, without the need for additional adjustment operations.

This layout fully considers the actual use needs of the operator, allowing the operator to put the pump casing into the groove more conveniently and quickly, thereby significantly improving the clamping efficiency, reducing the manual operation time and labor intensity during the clamping process, and further improving the efficiency and stability of the entire processing process.

[0013] Preferably, a rounded corner portion is provided between the top of the seating seat close to the second side wall and the second side wall of the groove portion.

[0014] By adopting the above technical solution, the fillet can play a transition role, the pump housing can slide into the groove and fit with the side wall, improving the stability and accuracy of the clamping, thereby reducing the steps of manually adjusting the position of the pump housing, improving the clamping efficiency, and enabling the pump housing to be quickly and accurately positioned in the groove; the fillet can play a transition role, and this ingenious design enables the pump housing to slide in more smoothly when placed in the groove and fit closely with the side wall. This fit not only improves the stability of the clamping, but also significantly improves the accuracy of the clamping. Due to the guiding role of the fillet, the pump housing can be aligned more naturally during the placement process, reducing the jamming or offset caused by shape mismatch. This design that reduces manual intervention not only saves time, but also reduces the error caused by manual adjustment, further improving the clamping efficiency. Finally, the pump housing can be quickly and accurately positioned in the groove, ensuring the smooth progress of the subsequent processing process, and also laying the foundation for high quality and high efficiency of processing.
