Unless otherwise stated, the orientation words such as "inner" and "outer" used in the present application refer to the contour of the corresponding parts.

[0037] As shown in Figure 1 , the present embodiment discloses an automatic oil injection and weighing device (hereinafter referred to as "device"). The gear box as a workpiece 100 is placed on a tray 200, and the tray 200 is placed on a feeding mechanism 300 to drive the tray 200 to move through the feeding mechanism 300 to realize the conveying of the gear box. The feeding mechanism 300 can be two horizontal and spaced automatic feeding tracks of the existing mechanism, which drives the lower side of the two ends of the tray 200 to realize the driving of the tray 200 and makes the tray 200 directly below suspended. The device comprises a rack 1, an oil injection mechanism 2, a lifting mechanism 3 and a weighing mechanism 4, which are used for oil injection and weighing detection of the workpiece 100 on the tray 200, so that the oil injection amount can meet the requirements.

[0038] As shown in Figure 1 , Figure 2 , and Figure 3 , the oil injection mechanism 2 is connected to the rack 1, and the oil injection mechanism 2 is used for injecting oil into the workpiece 100, and the oil injection mechanism 2 is suspended above the lifting mechanism 3. The specific structure of the rack 1 is not limited, and the rack 1 can provide a supporting effect so that the oil injection mechanism 2 can be suspended above the lifting mechanism 3. The fixed end of the lifting mechanism 3 is located below the feeding mechanism 300, and the telescopic end of the lifting mechanism 3 is arranged to pass through the feeding mechanism 300, so that the telescopic end of the lifting mechanism 3 can be vertically extended to above the feeding mechanism 300 or vertically retracted to below the feeding mechanism 300, that is, the telescopic end of the lifting mechanism 3 vertically extends and retracts between the two automatic feeding tracks. The fixed end of the lifting mechanism 3 is located below the feeding mechanism 300, and the telescopic end of the lifting mechanism 3 can pass through the feeding mechanism 300, so that when the tray 200 carrying the workpiece 100 is conveyed to below the oil injection mechanism 2, the feeding mechanism 300 stops, the tray 200 and the workpiece 100 are lifted up by the lifting mechanism 3, the tray 200 is separated from the feeding mechanism 300, and the workpiece 100 is close to the oil injection mechanism 2, thereby improving the reliability and accuracy of the positioning of the oil injection mechanism 2 and the workpiece oil injection position. The lifting mechanism 3 can be a cylinder or other structure that can realize vertical extension and retraction.

[0039] The weighing mechanism 4 is used to support the tray 200 and weigh the tray 200 and the workpieces 100 thereon before and after oiling. The lower side of the weighing mechanism 4 is connected to the telescopic end of the lifting mechanism 3 in a manner not limited. The lifting mechanism 3 drives the weighing mechanism 4 to move vertically, thereby driving the workpieces 100 on the tray 200 to move towards or away from the oiling mechanism 2, so that the tray 200 is separated from the feeding mechanism 300 and moves upward for oiling or moves downward after oiling to cooperate with the feeding mechanism 300 for continuous conveying. Since the telescopic end of the lifting mechanism 3 is connected to the weighing mechanism 4, the weight of the tray 200 and the workpieces 100 before oiling can be weighed while lifting the tray 200 and the workpieces 100, so that the initial weight value is obtained without additional movement of the workpieces 100 for weighing, thereby improving the efficiency. During the oiling process, the weighing mechanism 4 can be weighed in real time to obtain the oiling amount in time. After oiling, the tray 200 and the workpieces 100 are weighed to obtain the weight value after oiling. The oiling is realized by mechanical structure cooperation, which can improve the oiling efficiency and reduce the labor intensity. After the oiling amount meets the needs, the lifting mechanism 3 drives the weighing mechanism 4, the tray 200 and the workpieces 100 to descend synchronously, so that the tray 200 falls to cooperate with the feeding mechanism 300 for continuous conveying of the workpieces 100, reducing the need to move the workpieces 100 and improving the efficiency.

[0040] As shown in Figure 1 , Figure 2 and Figure 3 , optionally, the oiling mechanism 2 comprises an oiling assembly 21 and an oiling nozzle 22. One end of the oiling assembly 21 is connected to the rack 1, and the oiling nozzle 22 is connected to the other end of the oiling assembly 21. The oiling assembly 21 drives the oiling nozzle 22 to move, so that the oiling nozzle 22 is aligned with the oiling port of the workpiece 100, i.e. the oiling position, and the oiling nozzle 22 injects oil into the workpiece 100 through the oiling port. The oiling assembly 21 connects the oiling nozzle 22 to the rack 1, and through the driving action of the oiling assembly 21, the oiling nozzle 22 is moved to the oiling port of the workpiece 100, thereby improving the adjustability of the oiling nozzle 22 and the reliability of oiling.

[0041] As shown in Figure 1 , Figure 2 and Figure 3As shown, the oil injection assembly 21 comprises a first moving part 211, a second moving part 212 and a third moving part 213. The fixed end of the first moving part 211 is connected to the rack 1, and the fixed end of the second moving part 212 is connected to the movable end of the first moving part 211, so that the second moving part 212 can move in the first direction. The fixed end of the third moving part 213 is connected to the movable end of the second moving part 212, so that the third moving part 213 can move in the second direction. The first direction and the second direction are in the same horizontal plane and perpendicular to each other. The oil injection nozzle 22 is connected to the movable end of the third moving part 213, so that the oil injection nozzle 22 can move vertically. The first moving part 211 enables the oil injection nozzle 22 to move in the first direction, the second moving part 212 enables the oil injection nozzle 22 to move in the second direction, and the third moving part 213 enables the oil injection nozzle 22 to move vertically, so that the oil injection nozzle 22 can move in space, improving the flexibility of the oil injection nozzle 22, facilitating the alignment of the oil injection nozzle 22 with the oil injection hole of the workpiece 100, and improving the reliability of oil injection. The lifting mechanism 3 drives the tray 200 and the workpiece 100 to move upwards, which can not only make the tray 200 separate from the feeding mechanism 300, so that the tray 200 will not move horizontally after stopping below the oil injection mechanism 2 due to accidental movement of the feeding mechanism 300, affecting the positioning effect during oil injection, but also can reduce the vertical movement distance required by the oil injection mechanism 2 during oil injection, and improve the oil injection efficiency through the common movement of the workpiece 100 and the oil injection mechanism 2. The first moving part 211, the second moving part 212 and the third moving part 213 can all be structures of guide rails and sliding blocks, i.e. the guide rails are fixed ends, and the sliding blocks are movable ends.

[0042] Optionally, the oil injection assembly 21 comprises a valve, an oil conveying member and an oil storage member. The oil storage member is used for storing oil, and two ends of the oil conveying member are connected to the oil storage member and the oil injection nozzle 22 respectively, so that the oil can flow from the oil storage member to the oil injection nozzle 22. The valve is arranged on the oil conveying member, and is used for connecting or disconnecting the oil conveying member, so that the oil injection nozzle 22 starts or stops injecting oil. The oil storage member stores oil, and the valve is used for controlling the on-off of the oil conveying member. When the valve is opened, the oil conveying member is connected, and the oil in the oil storage member flows to the oil injection nozzle 22 through the oil conveying member; when the valve is closed, the oil conveying member is disconnected, and the oil cannot be conveyed, so that the oil injection nozzle 22 stops injecting oil. The valve can be used to control whether the oil injection nozzle 22 injects oil or not. The oil storage member can be an oil tank; the oil conveying member can be an oil conveying pipeline; and the valve can be a suitable control valve according to the needs. It should be noted that the oil storage member can be arranged higher than the oil injection nozzle 22, or a pump body such as a vane pump can be arranged, so that the oil in the oil tank can flow to the oil injection nozzle 22 to realize oil injection. The oil injection assembly 21 comprises a flow meter, and the flow meter is connected to the oil conveying member. The flow meter is used for measuring the injection amount. The flow meter is electrically connected to the valve, and the flow meter can open or close the valve. The flow meter measures the total injection amount flowing through the oil conveying member in a preset time, so as to obtain the injection amount input into the workpiece 100 by the oil injection mechanism 2, so that the injection amount at the oil injection mechanism 2 meets the needs; in combination with the injection amount weighing by the weighing mechanism 4, the accuracy of the injection amount input into the workpiece 100 can be improved.

[0043] As shown in Figure 1 , Figure 2 and Figure 3 , optionally, the weighing mechanism 4 comprises an electronic scale 41. The lower side of the electronic scale 41 is connected to the telescopic end of the lifting mechanism 3, and the electronic scale 41 is used for weighing the tray 200 and the workpiece 100 in real time. The lifting mechanism 3 drives the electronic scale 41 to move vertically, so that the electronic scale 41 can weigh the tray 200 and the workpiece 100 before and after oil injection in real time, so as to determine whether the injection amount is qualified.

[0044] As shown in Figure 1 , Figure 2 and Figure 3As shown, the weighing mechanism 4 optionally comprises a support assembly 42, which comprises a support body 421 and a positioning member 422. The lower end of the support body 421 is connected to the electronic scale 41, and the upper end of the support body 421 is used to support the tray 200. The tray 200 is provided with a positioning hole, and the positioning member 422 is connected to the support body 421 and is used to be fitted with the positioning hole, so that after the support assembly 42 is lifted, the positioning member 422 is arranged in the positioning hole. The positioning member 422 can be a positioning pin matched with the positioning hole. The support body 421 is used to support the tray 200, and the positioning member 422 arranged on the support body 421 is fitted with the positioning hole on the tray 200, which helps to improve the positioning accuracy of the tray 200 and reduce the risk of misalignment of the oil injection nozzle 22 and the oil injection port caused by horizontal movement of the tray 200. With the lifting of the telescopic end of the lifting mechanism 3, the positioning member 422 is arranged in the positioning hole, driving the tray 200 to separate from the feeding mechanism 300, so as to perform oil injection; after oil injection, the telescopic end of the lifting mechanism 3 is retracted downward, and the positioning member 422 is separated from the positioning hole, so that the tray 200 falls on the feeding mechanism 300 again, and the feeding mechanism 300 continues to convey the tray 200 and the workpiece 100 thereon. The support body 421 is a tool structure with a certain height; the positioning member 422 and the positioning hole are one-to-one corresponding, and the number and arrangement position of the two can be determined according to actual conditions; in this embodiment, the positioning member 422 and the positioning hole are both provided with two, and the two positioning holes are arranged at opposite positions of the tray 200.

[0045] Optionally, the weighing mechanism 4 comprises a display assembly arranged on one side of the electronic scale 41. The electronic scale 41 is electrically connected to the display assembly, and the display assembly is used to display the weighing weight value of the electronic scale 41. The display assembly displays the weight value, which can improve the visibility of the weighing result; at the same time, arranging the display assembly on one side of the electronic scale 41 can improve the reading convenience of the operator and reduce the safety hazard caused by being too close to the workpiece 100 and the electronic scale 41 during reading. The display assembly can be a bracket and a display screen, the bracket is arranged on one side of the electronic scale 41, the display screen is arranged on the bracket, and the display screen is electrically connected to the electronic scale 41. The display screen can select an existing structure.

[0046] As Figure 1 , Figure 2 and Figure 3As shown, the support body 421 is installed on the electronic scale 41, and the connection and separation of the support body 421 and the tray 200 are realized by the lifting of the electronic scale 41. The electronic scale 41 is lifted by using the lifting mechanism 3, and when the electronic scale 41 is lifted, the positioning piece 422 on the support body 421 is connected with the tray 200 for carrying the workpiece 100, the function of lifting the workpiece 100 is realized, the workpiece 100 and the tray 200 are separated from the automatic feeding track, at this time the extension end of the lifting mechanism 3 is moved from the initial state position 31 to the lifting state position 32, so that the workpiece 100 reaches the oil injection height. After the tray 200 for carrying the workpiece 100 is lifted, the tray 200 and the workpiece 100 without oil injection are weighed by the electronic scale 41. After the first weighing is completed, the oil injection assembly 21 drives the oil injection nozzle 22 to move above the oil injection hole of the workpiece 100, opens the valve, starts to inject oil into the workpiece 100, and measures the oil injection amount by using the flow meter, so that the valve is closed after it is detected that the oil injection amount meets the requirements, thereby stopping the oil injection. After the oil injection is completed, the oil injection assembly 21 drives the oil injection nozzle 22 to return to the initial position. The tray 200 after the oil injection and the workpiece 100 after the oil injection are weighed as a whole by the electronic scale 41 for the second time, and after the weighing is completed, the actual oil injection amount is obtained by comparing the weight before the oil injection and the weight after the oil injection, and whether the oil injection amount is qualified is judged, so as to improve the oil injection quality and facilitate timely adjustment of the oil injection amount.

[0047] Optionally, the oil injection mechanism 2 comprises an oil receiving assembly 23, and the oil receiving assembly 23 comprises an extension piece 231 and an oil receiving disc 232. The fixed end of the extension piece 231 is connected with the rack 1, and the extension end of the extension piece 231 is connected with the oil receiving disc 232. The extension piece 231 can selectively move the oil receiving disc 232 below the oil injection nozzle 22, and the oil receiving disc 232 is used for receiving the oil leakage of the oil injection nozzle 22.

[0048] As shown in Figure 1 , Figure 2 and Figure 3 , the extension piece 231 drives the oil receiving disc 232 to move, so that when the oil injection nozzle 22 is used for oil injection, the extension piece 231 drives the oil receiving disc 232 to retract, thereby reducing the risk of interference with the oil injection nozzle 22; when the oil injection nozzle 22 does not inject oil, the extension piece 231 is extended, so that the oil receiving disc 232 is located directly below the oil injection nozzle 22, and is used for receiving the oil liquid dropped from the oil injection nozzle 22, thereby reducing the risk of pollution caused by the oil liquid dropping on the workpiece 100. The extension piece 231 can be a cylinder, a hydraulic cylinder or an electric telescopic rod, etc. which can realize extension and retraction. The fixed end of the extension piece 231 can be connected with the fixed end of the second moving piece 212 through a connecting structure, and the specific structure of the connecting structure is not limited, so that the oil receiving disc 232 can move along the first direction with the oil injection nozzle 22, and through the movement and upward movement of the oil injection nozzle 22 along the second direction, combined with the extension of the extension piece 231, the oil injection nozzle 22 can be located directly above the oil receiving disc 232, and the oil receiving function is realized.

[0049] It can be understood that the device also includes necessary structures for connection, support, driving, positioning, limiting, control and the like, and existing structures can be selected as needed so that the device can normally operate; the shape, size, material and setting number of each part of the device can be determined as needed, and the corresponding functions can be realized.

[0050] The implementation principle of the automatic oil injection and weighing device is as follows: the rack 1 suspends the oil injection mechanism 2 above the lifting mechanism 3, the fixed end of the lifting mechanism 3 is located below the feeding mechanism 300, and the telescopic end of the lifting mechanism 3 can pass through the feeding mechanism 300, so that when the tray 200 carrying the workpiece 100 moves to the lower side of the oil injection mechanism 2, the tray 200 and the workpiece 100 are lifted upward by the lifting mechanism 3, the tray 200 is separated from the feeding mechanism 300, and then the workpiece 100 is close to the oil injection mechanism 2, improving the reliability and accuracy of the positioning of the oil injection mechanism 2 and the oil injection hole; since the telescopic end of the lifting mechanism 3 is connected to the weighing mechanism 4, the weight of the tray 200 and the workpiece 100 before oil injection can be weighed when the tray 200 and the workpiece 100 are lifted, and the initial weight value is obtained, without the need for additional movement of the workpiece 100 for weighing, improving the efficiency; oil injection is realized by mechanical structure cooperation, which can improve the oil injection efficiency and reduce the labor intensity; after the flow meter measures and judges that the oil injection amount meets the needs, the valve is closed to stop oil injection, and the weighing mechanism 4 weighs after oil injection, and then the lifting mechanism 3 drives the weighing mechanism 4, the tray 200 and the workpiece 100 to descend synchronously, so that the tray 200 falls to cooperate with the feeding mechanism 300, so as to continue to convey the workpiece 100, reduce the need to carry the workpiece 100, and improve the efficiency.

[0051] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
