Technical Field

[0001] The utility model relates to the technical field of vane pumps, in particular to an assembly positioning device for the cover end and the pump body of a vane pump. Background Technique

[0002] A vane pump is a pump in which the vanes in the rotor slots contact the pump housing (stator ring), and the liquid sucked in is pressed from the oil inlet side to the oil outlet side. When the rotor of the vane pump rotates, the vanes, under the action of centrifugal force and pressure oil, have their tips closely attached to the inner surface of the stator. In this way, the working volume formed by two vanes, the rotor, and the inner surface of the stator first increases from small to large to suck oil and then decreases from large to small to discharge oil. When the vanes rotate one week, one oil suction and one oil discharge are completed.

[0003] In the existing assembly of the cover end and the pump body of a vane pump, the cover end is gently placed on the pump body manually to ensure alignment with the sealing groove on the pump body, and bolts and nuts are used to tightly connect the cover end and the pump body to ensure a firm connection without looseness.

Detailed implementation mode

[0026] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and the specific implementation mode.

[0027] See Figures 1 to 7 As shown in the figure, the present invention provides an assembly positioning device for the cover end and the pump body of a vane pump, including a workbench 1, a top plate 2 is fixedly installed above the workbench 1, a linear driver 3 is arranged on the top plate 2, a lifting plate 4 is installed at the working end of the linear driver 3, and an adjusting and fixing assembly 5 for fixing and adjusting the position of the cover end of the vane pump is installed below the lifting plate 4. A positioning assembly 6 for positioning both sides of the pump body is installed on the workbench 1.

[0028] By placing the pump body on the workbench 1 and positioning both sides of the pump body through the positioning assembly 6, it is possible to prevent the pump body from shifting during the installation of the cover end of the vane pump, which affects the installation efficiency. The cover end of the vane pump is fixed by the adjusting and fixing assembly 5 and the position of the cover end of the vane pump can be adjusted until the central axes of the cover end of the vane pump and the pump body coincide. At this time, by starting the linear driver 3, the linear driver 3 can be a pushing cylinder. The linear driver 3 drives the lifting plate 4 to move, and the lifting plate 4 drives the cover end of the vane pump to move until the cover end of the vane pump coincides with the pump body, and the cover end of the vane pump and the pump body are fixed together by bolts.

[0029] See Figures 1 to 4As shown in the figure, the adjustment and fixing component 5 includes a driving plate 51, a first sliding groove 52, a first sliding block 53, a fixing seat 54, a first threaded rod 55, a first turntable 56, a moving plate 57 and a first fixing plate 58. The driving plate 51 is movably arranged on the lifting plate 4, and a driving component for driving the driving plate 51 to move is arranged on the lifting plate 4. The first sliding groove 52 is formed on the driving plate 51. The first sliding block 53 is arranged on the first sliding groove 52. The fixing seat 54 is arranged on the first sliding block 53. The first threaded rod 55 is arranged in the fixing seat 54, and one end of the first threaded rod 55 extends outwards through the fixing seat 54. The first turntable 56 is arranged at the extending end of the first threaded rod 55. The moving plate 57 is arranged on the first turntable 56. The first fixing plate 58 is installed on one side of the moving plate 57.

[0030] By placing both sides of the end of the vane pump cover on the fixing seat 54 and rotating the first turntable 56, the first turntable 56 drives the first threaded rod 55 to rotate, the first threaded rod 55 drives the moving plate 57 to move, the moving plate 57 drives the first fixing plate 58 on one side to move until the first fixing plate 58 fits against the upper end of the vane pump cover end and clamps it. A rubber layer is attached to the surface of the first fixing plate 58 that contacts the vane pump cover end, which increases the friction while preventing damage to the vane pump cover end, preventing movement or deviation during the assembly process, and driving the driving plate 51 to move through the driving component, so as to adjust the position of the vane pump cover end, ensuring accurate alignment between the pump cover end and the pump body during the assembly process and being able to adapt to vane pump cover ends of different models.

[0031] See Figure 4 As shown in the figure, smooth rods 59 are arranged on both sides of the first threaded rod 55 inside the fixing seat 54, and through holes for the smooth rods 59 to move are formed on the moving plate 57.

[0032] When the first threaded rod 55 drives the moving plate 57 to move, through holes are formed on both sides of the moving plate 57, and the moving plate 57 slides on the smooth rods 59 through the through holes, making the movement of the moving plate 57 more stable.
