Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a pump body positioning mechanism. Background Art

[0002] The cooling pump is one of the most indispensable components of the automobile cooling system. At present, the pump body of the cooling pump needs to be processed by milling, pressing steel balls and other processing procedures during production. When performing the above procedures, the pump body needs to be positioned and clamped.

[0003] At present, the structure for positioning and clamping the pump body is usually to place the pump body on the positioning column, and then press the pump body down into the positioning column by a clamping device. However, the pump body structure is usually a casting, which has a relatively large dimensional error. It is difficult to ensure the positioning accuracy of some processes that require high positioning accuracy (for example, pressing a steel ball with an outer diameter of only 3mm into the pump body) by positioning only by the positioning column.

[0004] It can be seen that there is still room for improvement in the current pump body positioning structure. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the background technology.

[0010] A side pressure assembly includes an orientation shaft located at the positioning column, wherein the orientation shaft is movably connected to the base and can move laterally toward the positioning column.

[0011] The beneficial effects of the utility model are as follows: the pump body positioning mechanism is equipped with a top pressure component and a side pressure component, which fixes the pump body from the top side and the lateral direction, thereby improving the stability of the pump body installation and ensuring the positioning accuracy of the pump body.

[0012] As some sub-schemes of the above technical scheme, the side pressure assembly also includes a first support, a first spring, a first pad, a first limit plate and a pull rod. The first support is arranged on the base. The first support is provided with a guide hole along the horizontal direction. The pull rod slides along the guide hole.

The directional axis is fixedly connected to the side of the pull rod adjacent to the positioning column. The first spring is located between the first support and the first pad to provide pressure to the first pad directed to the positioning column.

[0030] Combine the following Figure 1 to Figure 2 The embodiments of the present utility model are described.

[0031] The present embodiment relates to a pump body positioning mechanism, which provides a more stable way to fix the pump body.

[0032] The pump body positioning mechanism comprises:

[0033] Base 1;

[0034] A positioning column 2, arranged on the base 1;

[0035] A pressing assembly, the pressing assembly comprising a pressing block 31 located above the positioning column 2, the pressing block 31 being movably connected to the base 1 and movable toward the positioning column 2;

[0036] The side pressure assembly includes an orientation shaft 41 located on the positioning column 2 , and the orientation shaft 41 is movably connected to the base 1 and can move laterally toward the positioning column 2 .

[0037] The pump body positioning mechanism is equipped with a top pressure component and a side pressure component, which fixes the pump body from the top side and the lateral direction, thereby improving the stability of the pump body installation and ensuring the positioning accuracy of the pump body.

[0038] In this embodiment, the side pressure assembly is driven manually. Specifically, the side pressure assembly also includes a first support 46, a first spring 43, a first cushion block 44, a first limit plate 45 and a pull rod 42. The first support 46 is arranged on the base 1. The first support 46 is provided with a guide hole along the horizontal direction. The pull rod 42 slides along the guide hole. The pull rod 42 is arranged on the first support 46 along the horizontal direction. The first limit plate 45 is located on the side of the first support 46 that is away from the positioning column 2. The first limit plate 45 is fixedly connected to the pull rod 42. The first cushion block 44 is located between the first support 46 and the positioning column 2. The first cushion block 44 is fixedly connected to the pull rod 42. The directional axis 41 is fixedly connected to the side of the pull rod 42 adjacent to the positioning column 2. The first spring 43 is located between the first support 46 and the first cushion block 44 to provide pressure to the first cushion block 44 directed to the positioning column 2. The first spring 43 is supported by the first support 46, and applies a thrust to the pull rod 42 toward the positioning column 2 through the first cushion block 44. The first limit plate 45 limits the pull rod 42 from slipping out of the guide hole when the first spring 43 pushes the first cushion block 44. When the first spring 43 contacts the first cushion block 44, the directional shaft 41 remains in a state of extending toward the first support 46 under the action of the first spring 43. The first support 46 horizontally mounts the pull rod 42 on the side of the positioning column 2. Before the pump body is placed in the positioning column 2, the pull rod 42 is manually pulled back to make the pull rod 42 withdraw from the space of the positioning column 2, and then the pump body is placed in the positioning column 2, and the pull rod 42 is released. The pull rod 42 pushes the pump body tightly under the elastic force of the first spring 43, thereby fixing the pump body laterally.

[0039] In this embodiment, the pressing assembly plays a major role in fixing the pump body. The pressing assembly needs to be equipped with a driving device to clamp the pump body to ensure that the pump body is stably maintained in the positioning column 2. The pressing assembly includes a pressing driver 32 and a pressure plate. The pressing driver 32 is arranged on the base 1. The pressing driver 32 drives the pressure plate to move toward the positioning column 2 to clamp the pump body. The pressing assembly is equipped with a pressing driver 32, and the pump body is clamped on the positioning column 2 by the power of the driver, which can reduce the labor intensity of workers.

[0040] The pressing assembly further comprises a pressing seat 39, a pressing spring 33, a pressure rod 34 and a second limiting plate 35. The pressing driver 32 is connected to the pressing seat 39 by driving. The pressing seat 39 is provided with a guide hole. The pressure rod 34 slides along the guide hole. The pressure plate is located on the side of the pressure rod 34 facing the positioning column 2. The second limiting plate 35 and the pressure plate are respectively connected to the two sides of the pressure rod 34. The pressing spring 33 is located between the pressure plate and the pressing seat 39. When the pressing driver 32 is in action, the pressing seat 39 drives the pressing spring 33 to drive the pressure plate to press the pump body, so as to prevent the pressure plate from exerting too much pressure on the pump body and damaging the pump body. The second limiting plate 35 is connected to the side of the pressure rod 34 facing away from the positioning column 2, and when the pressing spring 33 holds the pressure plate and the pressure rod 34, it plays a role in limiting the pressure rod 34 from escaping from the guide hole. The pressing assembly is configured to include a pressing seat 39 , a pressing spring 33 , a pressing rod 34 and a second limiting plate 35 , thereby limiting the pressure of the pressing rod 34 in a simple and reliable manner.

[0041] The top pressure driver 32 is a cylinder. The top pressure driver 32 adopts a cylinder, which has the advantage of low cost.

[0042] After the top pressure assembly is installed, it is located above the positioning column 2. When the pump body is placed into the positioning column 2, the space will be blocked. For this reason, the top pressure assembly also includes a side shift driver 36 and a side shift seat 37. The side shift driver 36 drives the side shift seat 37 to move laterally. The top pressure driver 32 is arranged on the side shift seat 37. Before the pump body is placed into the positioning column 2, the side shift driver 36 drives the top pressure driver 32 to move laterally away from the positioning column 2, and the space near the positioning column 2 is released so that the positioning column 2 can be placed.

[0043] The side shift driver 36 is a cylinder. The side shift driver 36 adopts a cylinder, which has the advantage of low cost.

These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
