Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically a processing fixture for an electric compressor housing. Background Technology

[0002] The electric compressor housing is an important component of the compressor in the thermal management system of new energy vehicles. Its main structure is die-cast, but it needs to be machined at multiple locations on its upper end face and outer side wall. Moreover, the machined surfaces are not on the same plane, so multiple clamping fixtures are often used to perform the machining. This not only results in low machining efficiency but also makes it impossible to guarantee the accuracy of each clamping, leading to a high defect rate.

[0003] In addition, since the end face of the electric compressor housing needs to be machined and the overall thickness of the housing is relatively thin, traditional calipers cannot be used to clamp the outer wall of the housing when clamping the electric compressor housing to avoid deformation of the electric compressor housing. Cylinders and clamps cannot be used to press the end face of the electric compressor housing, so the end face cannot be machined. Therefore, a new clamping structure is needed to meet the machining requirements of the electric compressor housing. Utility Model Content

[0004] This utility model provides a machining fixture for electric compressor housings, which can solve the problems that existing traditional fixtures cannot meet multi-angle machining requirements and that traditional clamping methods are not suitable for clamping electric compressor housings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machining fixture for an electric compressor housing, comprising a base plate, with a power drive support seat and a rotating support seat respectively mounted on the upper two ends of the base plate. A rotating mounting plate connected to the main shaft on the power drive support seat is provided between the power drive support seat and the rotating support seat. At least two clamping stations are mounted on the upper side of the rotating mounting plate. Each clamping station includes multiple side top supports evenly distributed around the center of the clamping station and a lower clamping assembly installed between adjacent side top supports. The side top supports abut against the upper outer side wall of the electric compressor housing, and the lower clamping assembly presses the lower step of the electric compressor housing. By providing a rotating mounting plate that can rotate around the power drive support seat and the rotating support seat, the electric compressor housing can meet the machining requirements of multiple angles and positions in the clamped state. Moreover, the clamping method combining the side top supports and the lower clamping assembly will not cause deformation of the electric compressor housing and leaves room for machining on the upper end face.

[0006] Preferably, the rotating mounting plate is equipped with support vertical plates at both ends, and one end of the main shaft is connected to the support vertical plates. The support vertical plates can support the rotating mounting plate and ensure stable rotation.

[0007] Preferably, the side top support includes a column and a pneumatic spring installed on the upper end of the column. The end of the pneumatic spring is provided with a push rod. The pneumatic spring can apply a lateral thrust to the push rod, so that multiple push rods can apply radial force to the electric compressor housing, which can reduce the vibration of the electric compressor housing during processing.

[0008] Preferably, the lower clamping assembly includes a clamping cylinder and a pressure plate installed on the upper end of the clamping cylinder. The pressure plate extends toward the lower step of the electric compressor housing and can press down on the lower part of the electric compressor housing to ensure that the electric compressor housing does not move.

[0009] Preferably, the clamping cylinder is embedded in the mounting slot on the rotating mounting plate, which can position the clamping cylinder so that the pressure plate on the clamping cylinder can press down on the electric compressor housing.

[0010] Preferably, the rotating mounting plate is provided with a hollow through groove at the middle of the clamping station to facilitate the falling of metal debris generated during processing onto the bottom plate.

[0011] Preferably, the upper side of the base plate is provided with a sliding groove, and the lower side of the power drive support and the rotating support is provided with a slider embedded in the sliding groove, so as to facilitate the adjustment of the position of the power drive support and the rotating support.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] With its simple structure, the rotating mounting plate, which can rotate around the power drive support and the rotating support, allows the electric compressor housing to meet the processing requirements of multiple angles and positions while in a clamped state. Multiple clamping stations can be installed on the rotating mounting plate. Moreover, the clamping method, which combines the side top bracket with the lower clamping component, will not cause deformation of the electric compressor housing and leaves room for processing on the upper end face, thus ensuring processing efficiency and accuracy.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-3 As shown, this utility model provides the following technical solution to solve the problems that existing traditional fixtures cannot meet multi-angle processing requirements and that traditional clamping methods are not suitable for clamping electric compressor housings: A processing fixture for an electric compressor housing includes a base plate 1. A power drive support 4 and a rotating support 3 are respectively installed at both ends of the upper side of the base plate 1. A rotating mounting plate 2 connected to the main shaft 7 on the power drive support 4 is provided between the power drive support 4 and the rotating support 3. At least two clamping stations 5 are installed on the upper side of the rotating mounting plate 2. Each clamping station 5 includes fixtures evenly spaced around its center. Multiple side-top supports 51 are distributed and a lower clamping assembly 53 is installed between adjacent side-top supports 51. The side-top supports 51 abut against the upper outer wall of the electric compressor housing, and the lower clamping assembly 53 presses the lower step of the electric compressor housing. By setting a rotating mounting plate 2 that can rotate around the power drive support 4 and the rotating support 3, the electric compressor housing can meet the processing requirements of multiple angles and multiple positions in the clamping state. Moreover, the clamping method of combining the side-top supports 51 and the lower clamping assembly 53 will not cause deformation of the electric compressor housing and leave space for processing on the upper end face.

[0021] Specifically, the power drive support 4 and the rotating support 3 are arranged coaxially opposite each other. The main shaft 7 on the power drive support 4 is driven to rotate by a drive motor on one side. There are two clamping stations 5 on the rotating mounting plate 2, which can simultaneously install and process the electric compressor housing.

[0022] The side top brackets 51 are arranged in a triangular position to support the side of the electric compressor housing from three points. However, they do not clamp the housing, but only support it, so the electric compressor housing will not be deformed. The electric compressor housing is mainly clamped and fixed by the lower clamping components 53, which are also arranged in a triangular position. Therefore, the three side top brackets 51 and the three lower clamping components 53 together fix and limit the electric compressor housing.

[0023] When in use, the machining fixture in this embodiment is installed on a machining center or milling and turning center, and the angle of the rotating mounting plate 2 is rotated according to different machining positions.

[0024] In this embodiment, as Figure 3 As shown, the rotating mounting plate 2 has support vertical plates 8 installed at both ends, and one end of the main shaft 7 is connected to the support vertical plate 8. The support vertical plate 8 can support the rotating mounting plate 2 and make it rotate stably.

[0025] In this embodiment, as Figure 3 As shown, the side top support 51 includes a column and a pneumatic spring 55 installed on the upper end of the column. The end of the pneumatic spring 55 is provided with a push rod 52. The pneumatic spring 55 can apply a lateral thrust to the push rod 52, so that multiple push rods 52 can apply radial force to the electric compressor housing, which can reduce the vibration of the electric compressor housing during processing. The column is provided with an air passage, which can be connected to an air source, so that the pneumatic spring 55 can always be applied with an outward thrust.

[0026] like Figure 3 As shown, the lower clamping assembly 53 includes a clamping cylinder 56 and a pressure plate 54 installed on the upper end of the clamping cylinder 56. The pressure plate 54 extends into the lower step of the electric compressor housing and can press down on the lower part of the electric compressor housing to ensure that the electric compressor housing does not move.

[0027] Simultaneously, the clamping cylinder 56 is embedded in the mounting slot on the rotating mounting plate 2, which allows the clamping cylinder 56 to be positioned so that the pressure plate 54 on the clamping cylinder 56 can press against the electric compressor housing. Figure 3 As shown, a hollow through groove 6 is provided on the rotating mounting plate 2 at the middle position of the clamping station 5, so that the metal scraps generated during processing can fall onto the bottom plate 1.

[0028] like Figure 1 As shown, the upper side of the base plate 1 is provided with a sliding groove 9, and the lower side of the power drive support 4 and the rotating support 3 is provided with a slider embedded in the sliding groove 9, which facilitates the adjustment of the position of the power drive support 4 and the rotating support 3.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
