The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0028] like Figure 1-4 As shown, a water-cooled motor housing automatic deburring and grasping device comprises a base 1, on which two or more clamping assemblies 2 for grasping a workpiece 100 are arranged, and on which a pressing assembly 3 is further arranged, wherein the pressing assembly 3 is located between the clamping assemblies 2, and the pressing assembly 3 is used to press the clamped workpiece 100, and the grasping driving direction of the clamping assembly 2 and the pressing driving direction of the pressing assembly 3 are set at an angle;

[0029] The clamping assembly 3 includes a clamping driver 31 and a clamping plate 32. The clamping driver 31 is connected to the base 1. The clamping plate 32 is located at the end of the clamping driver 31 away from the base 1. The clamping plate 32 is connected to the driving end of the clamping driver 31.

[0030] A connecting seat 4 connected to a robot (not shown in the figure) is arranged on a side of the base 1 away from the clamping assembly 2 .

[0031] In this embodiment, if Figure 1 , 4 As shown, the workpiece 100 is a cylindrical structure, and the workpiece 100 is provided with an inner cavity 101, and the inner cavity 101 is provided with a bearing mounting base 102 separating the inner cavity 101;

[0032] The grabbing driving direction of the clamping assembly 2 is arranged perpendicular to the pressing driving direction of the pressing assembly 3;

[0033] When grabbing the workpiece 100, the robot first drives the grabbing device to the top of the workpiece 100 placement position, and the clamping assembly 2 first drives the side wall of the workpiece 100 to be clamped. After completion, the clamping driver 31 drives the clamping plate 32 to move toward the bearing mounting base 102 until it reaches the set position. After completion, the robot removes burrs and grinds multiple parts of the workpiece 100;

[0034] The above structure, under the joint action of the clamping assembly 2 and the pressing assembly 3, limits the freedom of the workpiece 100 to move up, down, left and right relative to the grasping device, ensures the stability of the workpiece 100 during processing, improves the positioning accuracy of deburring and grinding, ensures the consistency of deburring and grinding of the workpiece 100, and improves the quality of the workpiece 100.

[0035] Further, such as Figure 1 , 2 As shown, the clamping assembly 3 also includes two or more coarse positioning blocks 33, which are distributed circumferentially around the axis of the workpiece 100, one end of the coarse positioning block 33 is connected to the base 1, and the other end is connected to the clamping driver 31 through a support plate 34.

[0036] In this embodiment, the above structure limits the downward movement distance of the grasping device relative to the workpiece 100 through the coarse positioning block 33, so that the upper and lower positioning before grasping is more effective and accurate.

[0037] Further, such as Figure 1 , 2As shown, the clamping assembly 2 includes a clamping driver 21, and the clamping driver 21 is provided with two driving ends, and the two driving ends are coaxially arranged opposite to each other. A clamping plate 22 is respectively arranged on the two driving ends, and the clamping plate 22 is located on the outside of the workpiece 100, and the clamping plate 22 is arranged parallel to the axis of the workpiece 100.

[0038] In this embodiment, when the clamping driver 21 is driven, the two clamping plates 22 are driven to symmetrically approach or move away from the axis of the workpiece 100, thereby avoiding the machining accuracy affected by the clamping deviation of the workpiece 100 and achieving accurate grasping and positioning.

[0039] In this embodiment, the clamping driver 21 is a finger cylinder with a guide rod, which has good rigidity, smooth driving, and centering effect, and is not affected by the expansion of the casting.

[0040] Further, such as Figure 2 , 3 As shown, a plurality of limiting protrusions 221 are provided on the side of the clamping plate 22 facing the workpiece 100 .

[0041] In this embodiment, if Figure 1 , 4 As shown, a cooling water channel 104 is provided on the outer surface of the workpiece 100, and a plurality of heat sinks 103 are provided on the cooling water channel 104. The heat sinks 103 form a concave-convex surface on the cooling water channel 104. When grasping, the limiting protrusion 221 cooperates with the outer concave-convex surface of the workpiece 100, thereby effectively limiting the freedom of rotation of the workpiece 100 relative to the clamping plate 22, so that the clamping is stable.

[0042] Further, such as Figure 2 , 3 As shown, a connecting plate 5 is arranged between the clamping plate 22 and the driving end of the pressing driver 31 , and a plurality of elastic components 6 are arranged between the connecting plate 5 and the clamping plate 22 .

[0043] In this embodiment, the above structure effectively controls the clamping force, avoids damage to the workpiece 100 caused by excessive clamping force, and improves clamping reliability.

[0044] Further, such as Figure 2 , 3 As shown, the elastic component 6 includes a guide sleeve 61, a guide rod 62 and an elastic member 63. The guide rod 62 is slidably connected to the guide sleeve 61, the guide rod 62 is connected to the connecting plate 5, the guide sleeve 61 is connected to the clamping plate 22, and the elastic member 63 is arranged between the connecting plate 5 and the clamping plate 22 through the connecting rod 64.

[0045] In this embodiment, the guide sleeve 61 and the guide rod 62 are used to limit the freedom of the clamping plate 22 to move except in the direction of approaching or moving away from the connecting plate 5, thereby preventing the clamping plate 22 from shaking relative to the connecting plate 5 during clamping; the elastic member 63 acts as a buffer to prevent damage to the workpiece 100 caused by excessive clamping force.

[0046] Furthermore, the elastic member 63 is a spring or rubber or a combination thereof.

[0047] Further, such as Figure 1 , 2 As shown, a sensor 7 is arranged on the base 1 .

[0048] In this embodiment, the sensor 7 is used to detect whether the workpiece 100 is in place.

[0049] Furthermore, the driving end of the clamping driver 31 is coaxially arranged with the axis of the workpiece 100 .

[0050] In this embodiment, in the above structure, the clamping force output by the clamping driver 31 acts on the middle of the workpiece 100, further ensuring that the workpiece 100 is firmly grasped.

[0051] Further, such as Figure 2 As shown, a buffer element 8 is provided on the side of the pressure plate 32 facing the workpiece 100 .

[0052] In this embodiment, the above structure prevents the workpiece 100 from being damaged due to excessive pressing force, thereby protecting the workpiece 100 well.

[0053] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
