If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] An end cover processing fixture according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0039] Reference Figure 1 , Figure 2 and Figure 3 An end cover processing fixture according to an embodiment of the utility model includes a base plate 100, a positioning assembly and a clamping assembly.

[0040] Reference Figure 4 and Figure 5 In some specific embodiments, an elastic support assembly is also provided on the base plate 100, and the elastic support assembly includes a mounting seat 210 fixed on the base plate 100, a support pin 220 slidably provided on the mounting seat 210, and an elastic member 230 driving the support pin 220 to push up, and the support pin 220 is used to be inserted into the mounting hole at the bottom of the end cover to support the end cover.

[0041] It can be understood that by inserting the support pin 220 into the mounting hole at the bottom of the end cover, the support pin 220 is abutted against the hole opening of the mounting hole to support the end cover. After the end cover squeezes the support pin 220 downward, the support pin 220 squeezes the elastic member 230 downward, so that the upward elastic force generated by the elastic member 230 after being squeezed can support the end cover upward, thereby offsetting a portion of the downward force exerted on the end cover by the machining tool during machining, thereby reducing the risk of deformation of the end cover.

[0042] Furthermore, the top of the support pin 220 has a tapered portion 240, and the tapered portion 240 is used to abut the mounting hole at the bottom of the end cover, so that the tapered portion 240 can guide the mounting hole at the bottom of the end cover, making it easier to insert the support pin 220 into the mounting hole.

[0043] The positioning assembly is arranged on the base plate 100 and includes a positioning block 110 and a positioning column 120. The positioning block 110 and the positioning column 120 are respectively positioned in cooperation with the outer side surface of the end cover, so that the clamping position of the end cover on the fixture is accurate.

[0044] Specifically, the positioning block 110 is provided with a first waist hole 130 , the length direction of the first waist hole 130 is arranged horizontally in a direction close to and away from the end cover, and the first waist hole 130 is provided with a first bolt, which is threadedly connected and fixed to the bottom plate 100 .

[0045] It can be understood that after loosening the first bolt, the positioning block 110 can be moved along the length direction of the first waist hole 130, so as to facilitate the adjustment of the position of the positioning block 110, thereby facilitating the adjustment of the positioning position of the positioning block 110 relative to the end cover, and then, adapting to the positioning of end covers with different size deviations. After the position of the positioning block 110 is adjusted, the positioning block 110 is locked and fixed by tightening the first bolt.

[0046] In addition, the positioning column 120 has an eccentric hole 140, the axis of the positioning column 120 is not coaxial with the axis of the eccentric hole 140, the eccentric hole 140 is provided with a second bolt, the second bolt is threadedly connected and fixed to the base plate 100, and the positioning column 120 rotates around the axis of the eccentric hole 140 to adjust the positioning position.

[0047] It can be understood that after loosening the second bolt, the positioning column 120 can be rotated so that the positioning column 120 rotates around the axis of the eccentric hole 140, which makes it easy to adjust the position of the positioning column 120 close to the end cover, thereby making it easy to adjust the positioning position of the positioning column 120 relative to the end cover, and further, to adapt to the positioning of end covers with different size deviations. After adjusting the positioning column 120, the positioning column 120 is locked and fixed by tightening the second bolt.

[0048] In some specific embodiments, the top of the positioning column 120 has a guide cone 180, so that the guide cone 180 can guide the end cap, making it easier to put the end cap into the positioning assembly.

[0049] In some specific embodiments, the top of the eccentric hole 140 has a recessed portion 190 for accommodating the nut of the second bolt, thereby preventing the nut of the second bolt from protruding from the top of the positioning column 120 and interfering with the end cover.

[0050] In some specific embodiments, the positioning block 110 is provided with at least two first waist holes 130, and at least two first waist holes 130 are arranged in parallel, so that the first bolts of the two first waist holes 130 cooperate to prevent the positioning block 110 from rotating, thereby making the positioning block 110 more stable and less likely to rotate.

[0051] In some specific embodiments, the top of the positioning block 110 on the side close to the end cover has a guiding slope 200, so that the guiding slope 200 can guide the end cover, making it easier to put the end cover into the positioning assembly.

[0053] For the clamping assembly, the clamping assembly includes a support seat 150, a pressure arm 160 and a first cylinder 170. The support seat 150 is used to support the bottom of the end cover, and the first cylinder 170 is used to drive the pressure arm 160 to press and loosen the top of the end cover, thereby conveniently and quickly fixing the end cover on the clamp.

[0054] In some specific embodiments, the pressing arm 160 and the supporting seat 150 are arranged correspondingly up and down, and the pressing arm 160 and the supporting seat 150 cooperate to clamp the end cap up and down, so that the clamping of the end cap by the pressing arm 160 and the supporting seat 150 is more stable. In addition, the supporting seat 150 can support and limit the bottom of the position where the end cap is squeezed by the pressing arm 160, so as to prevent the pressing arm 160 from deforming the end cap.

[0055] In some specific embodiments, a plurality of clamping assemblies are provided, and the plurality of clamping assemblies are arranged along the outer contour of the end cover, so that the clamping of the end cover by the plurality of clamping assemblies is more stable.

[0056] In some specific embodiments, it also includes a frame, two coaxially rotatable wheels arranged on the frame, and a first motor that drives the wheels to rotate. A support plate is provided on the side where the two wheels are close to each other, and the bottom plate 100 is arranged between the two wheels. The two support plates respectively support the bottom of both sides of the bottom plate 100. The wheels rotate to drive the bottom plate 100 to flip, thereby facilitating the adjustment of the angle of the end cover on the fixture so as to process the mounting surfaces on the end cover in different directions.
