The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the embodiments of the present application will be described below with reference to the drawings.

[0068] Please refer to Figures 1-5 The embodiments of the present application provide a differential mechanism in-place mechanism, comprising: at least one placement structure 1, a positioning structure 2 and a support structure 3;

[0070] The positioning structure 2 is fixed on the support structure 3, and the positioning structure 2 is used for contacting the differential mechanism 4 on the at least one placement structure 1, and the positioning structure 2 is used for fixing the differential mechanism 4 on the placement structure 1.

[0071] In this example, the differential mechanism 4 is placed on the placement structure 1 to manage the differential mechanism 4; the differential mechanism 4 is fixed on the placement structure 1 by setting the positioning structure 2, the positioning of the differential mechanism 4 is realized, so that the differential mechanism in-place mechanism can be subjected to strong vibration in time, and will not fall off from the placement structure 1, ensuring the safety of the differential mechanism; the support mechanism is set to provide effective support for the placement structure 1 and the positioning structure 2.

[0072] In a preferred embodiment, the placement structure 1 comprises a fixed shaft 11 and a fixed disc 12;

[0073] The fixed shaft 11 is used for inserting into the insertion hole of the differential mechanism 4;

[0074] The bottom end of the fixed shaft 11 is connected with the fixed disc 12, and the fixed disc 12 is fixed on the support structure 3.

[0075] In this example, the fixed shaft 11 is set to insert into the insertion hole to preliminarily position the differential 4; the fixed disc 12 is set to improve the connection strength between the fixed shaft 11 and the support structure 3; wherein the fixed disc 12 is fixed on the support plate 31 of the support structure 3 by bolts or rivets.

[0076] Illustratively, the fixed shaft 11 is designed as a cylinder, and its diameter should be slightly smaller than the diameter of the insertion hole of the differential 4 to ensure smooth insertion and stability. The length of the fixed shaft 11 should be long enough to be fully inserted into the insertion hole and provide sufficient support force. The fixed shaft 11 should be made of high-strength, wear-resistant materials such as alloy steel or stainless steel to ensure its stability and durability during use. The surface of the fixed shaft 11 should be finished to improve its surface finish and wear resistance. The surface of the fixed shaft 11 can be chrome-plated or nickel-plated to enhance its corrosion resistance.

[0077] The fixed disc 12 is designed as a circle or a square, and its diameter or side length should be greater than the diameter of the fixed shaft 11 to ensure that it can provide sufficient support area. The thickness of the fixed disc 12 should be determined according to actual needs, and it should be thick enough to withstand the weight of the differential and the vibration generated during operation. The fixed disc 12 should be made of high-strength, lightweight materials such as aluminum alloy or magnesium alloy to reduce overall weight and improve structural stability. The bottom of the fixed disc 12 should be designed with connection holes or threaded holes that match the support plate 31 of the support structure 3, so that it can be firmly connected with the support plate 31 of the support structure 3 through bolts, welding or riveting, etc. Shock-absorbing pads or rubber pads can be installed on the upper surface of the fixed disc 12 as needed to reduce vibration and noise.

[0078] In a preferred embodiment, the positioning structure 2 comprises a guide rod cylinder 21 and at least one top rod 22;

[0079] The guide rod cylinder 21 is fixed on the support structure 3;

[0080] One end of at least one top rod 22 is inserted into the guide rod cylinder 21, and the other end of at least one top rod 22 respectively faces at least one placement structure 1, respectively for contacting the differential 4 on the placement structure 1.

[0081] In this example, the extension and retraction of the top rod 22 is controlled by the guide rod cylinder 21, and the differential 4 is fixed on the placement structure 1 by the contact between the top rod 22 and the differential 4 on the placement structure 1, thereby realizing the positioning of the differential 4.

[0082] Exemplarily, the guide rod cylinder 21 is fixed on the support structure 3 through a dedicated mounting seat or support. The mounting seat or support should be designed with sufficient strength and rigidity to ensure the stability of the cylinder during operation. The guide rod cylinder 21 needs to be connected to a gas source to provide power. The gas source connection should be firm and reliable to avoid air leakage. At the same time, corresponding pneumatic control elements (such as solenoid valves, throttle valves, etc.) should be set to control the movement speed and direction of the cylinder. The ejector rod 22 is designed as a cylinder or a square, and its diameter or side length should be slightly smaller than the inner diameter of the guide rod cylinder 21 to ensure smooth insertion and sliding.

[0083] The length of the ejector rod 22 should be determined according to actual needs and should be long enough to contact the differential 4 on the placement structure 1. The ejector rod 22 should be made of high-strength, wear-resistant materials such as alloy steel or stainless steel. These materials have good mechanical properties and corrosion resistance, which can meet the needs of long-term use. The surface of the ejector rod 22 should be finished to improve its surface finish and wear resistance. At the same time, the surface of the ejector rod 22 can be chrome-plated or nickel-plated to enhance its corrosion resistance.

[0084] In a preferred embodiment, the support structure 3 comprises a support plate 31, a support block 32 and a support column 33.

[0085] One end of the upper surface of the support plate 31 is connected to the placement structure 1.

[0086] The other end of the upper surface of the support plate 31 is connected to the support block 32, and the guide rod cylinder 21 is fixed on the top of the support block 32.

[0087] The top of the support column 33 is connected to the lower surface of the support plate 31.

[0088] In this example, the placement structure 1, the support block 32 and the support column 33 are fixed by setting the support plate 31.

[0089] By setting the support block 32, the guide rod cylinder 21 is lifted to a specified height, which is beneficial to the contact between the ejector rod 22 and the differential 4.

[0090] By setting the support column 33, the differential 4 can reach a sufficient height to facilitate the worker or robot hand to grab the differential 4 from the placement structure 1 on the support structure 3.

[0091] Exemplarily, the support plate 31 is designed in a rectangular shape or a customized shape according to actual needs, and the size should be large enough to support the placement structure 1 and the support block 32. The thickness of the support plate 31 should be determined according to the bearing weight and rigidity requirements to ensure that no deformation occurs during use. The support plate 31 should be made of high-strength and wear-resistant materials such as steel or aluminum alloy to meet the needs of long-term use. One end of the upper surface of the support plate 31 is designed with a connecting hole or groove matched with the placement structure 1, which is firmly connected with the placement structure 1 through bolts, pins or welding, etc. The other end is designed with an interface connected with the support block 32, which can be bolted, slotted or other suitable connection methods.

[0092] The support block 32 is designed in a block structure, and the size should adapt to the fixing needs of the guide rod cylinder 21. The height of the support block 32 should ensure that the guide rod cylinder 21 can be firmly fixed on the top, and keep a proper distance with the upper surface of the support plate 31. The support block 32 should be made of the same or similar materials as the support plate 31 to ensure the strength and stability of the entire support structure 3. The top of the support block 32 is designed with a fixing hole or groove matched with the guide rod cylinder 21, which firmly fixes the guide rod cylinder 21 on the support block 32 through bolts, nuts or other fasteners. If the support block 32 needs to bear larger force or vibration, reinforcing ribs can be designed inside or outside to improve its rigidity and anti-vibration ability.

[0093] The support column 33 is designed in a columnar structure, and the diameter or side length should be determined according to the bearing weight and stability requirements. The height of the support column 33 should ensure that the support plate 31 can be placed stably on the top, and keep a proper distance with the ground or foundation. The support column 33 should be made of high-strength and corrosion-resistant materials such as steel or stainless steel to meet the needs of long-term use. The top of the support column 33 is designed with a connecting hole or groove matched with the lower surface of the support plate 31, which firmly fixes the support plate 31 on the support column 33 through bolts, welding or other connection methods. The bottom of the support column 33 can be designed with a flange or base to be fixed on the ground or foundation through bolts or welding, etc.

[0094] Optionally, the support structure 3 further comprises a support base 38;

[0095] The top of the support base 38 is connected with the bottom of the support column 33, and the end face of the support base 38 is larger than that of the support column 33. The support base 38 can be fixed on the building, structure or fixed equipment through screws.

[0096] The support base 38 is used to ensure the stability of the in-place mechanism of the differential.

[0097] In a preferred embodiment, the support structure 3 further comprises a sheet metal shell 34;

[0098] The sheet metal cover 34 is located above the support plate 31 and is connected with the support plate 31;

[0099] The top rod 22 passes through the sheet metal cover 34 at one end of the placement structure 1 and contacts the differential 4 on the placement structure 1.

[0100] In this example, the sheet metal cover 34 is buckled on the support plate 31, so that the sheet metal cover 34 and the support plate 31 form a channel around it, and the top rod 22 will pass through the channel to contact the differential 4. By setting the sheet metal cover 34 to isolate the top rod 22 when the placement structure 1 and the differential 4 are separated, it avoids the worker's fingers or the mechanical hand from hitting the top rod 22 when placing or grabbing the differential 4, ensuring the safety of the worker, the mechanical hand, and the top rod 22.

[0101] Exemplarily, the sheet metal cover 34 is designed to match the shape of the space above the support plate 31, which can be rectangular, square or other customized shape. The size should be large enough to completely buckle on the support plate 31 and leave enough space for the top rod 22 to pass through. The sheet metal cover 34 should be made of high-strength, corrosion-resistant sheet metal materials such as cold-rolled steel plate, stainless steel plate, etc. The thickness of the material should be determined according to the size of the cover and the load requirement to ensure its stiffness and durability. The connection between the sheet metal cover 34 and the support plate 31 can be welding, bolt connection or buckle connection, etc. Welding connection is firm and reliable, but the processing cost is higher; bolt connection is convenient for disassembly and maintenance, but it may require additional connecting parts; buckle connection is easy to install, but it may not be suitable for large or heavy covers.

[0102] In a preferred embodiment, the support structure 3 further comprises a first proximity switch 35, a second proximity switch 36 and a switch mounting bracket 37;

[0103] The first proximity switch 35 is located between the guide rod cylinder 21 and the placement structure 1, and the second proximity switch 36 is located between the first proximity switch 35 and the guide rod cylinder 21;

[0104] The first proximity switch 35 and the second proximity switch 36 are respectively fixed on the switch mounting bracket, and the switch mounting bracket is fixed on the support plate 31;

[0105] The first proximity switch 35 generates a first in-place signal if it detects the top rod 22;

[0106] The first proximity switch 35 generates a first absence signal if it does not detect the top rod 22;

[0107] The second proximity switch 36 generates a second in-place signal if it detects the top rod 22;

[0108] The second proximity switch 36 generates a second absence signal if the top rod 22 is not detected.

[0109] In this example, the first proximity switch 35 and the second proximity switch 36 can be connected in a preset controller, the first proximity switch 35 sends a first arrival signal and a first absence signal to the controller, and the second proximity switch 36 sends a second arrival signal and a second absence signal to the controller.

[0110] The first proximity switch 35 displays the first arrival signal and the second absence signal through the first light bulb; and the second proximity switch 36 displays the second arrival signal and the second absence signal through the second light bulb.

[0111] The first proximity switch 35 generates a first arrival signal, and the second proximity switch 36 generates a second arrival signal, indicating that the differential 4 positioned by the top rod 22 is placed on the placement structure 1; at this time, the controller can generate a differential 4 positioning signal.

[0112] The first proximity switch 35 generates a first absence signal, and the second proximity switch 36 generates a second arrival signal, indicating that the differential pin is not placed on the placement structure 1; at this time, the controller can generate a differential 4 absence signal.

[0113] The first proximity switch 35 generates a first absence signal, and the second proximity switch 36 generates a second absence signal, indicating that the moving position of the top rod 22 is abnormal; at this time, the controller can generate a guide rod cylinder 21 abnormal signal.

[0114] In a preferred embodiment, the in-place mechanism of the differential further comprises: at least one guide column 5.

[0115] One of the guide columns 5 is used to insert the differential 4 on one of the placement structures 1, and the guide column 5 is used to guide the differential 4.

[0116] At least one of the guide columns 5 corresponds to at least one of the placement structures 1 respectively, and is sequentially arranged and fixed on the support structure 3.

[0117] In this example, by arranging the guide column 5, the differential 4 guides the process of inserting the fixed shaft 11 into the differential 4 while inserting the fixed shaft 11 into the placement structure 1, so as to ensure that the differential 4 can be smoothly inserted into the fixed shaft 11.

[0118] In a preferred embodiment, the in-place mechanism of the differential further comprises: at least one anti-rotation column 6.

[0119] One of the anti-rotation posts 6 is in contact with a differential 4 on one of the placement structures 1, and the anti-rotation post 6 is used to prevent the differential 4 from rotating;

[0120] At least one of the anti-rotation posts 6 corresponds to at least one of the placement structures 1, and is sequentially arranged and fixed on the support structure 3.

[0121] In this example, the anti-rotation posts 6 are arranged to be in contact with the outer surface of the differential 4, so as to prevent the differential 4 from rotating around the fixed shaft 11, thereby ensuring the stability of the differential 4 on the placement structure 1.

[0122] In a preferred embodiment, the in-place mechanism of the differential further comprises at least one in-place proximity switch 7.

[0123] One of the in-place proximity switches 7 corresponds to one of the placement structures 1, and the in-place proximity switch 7 is fixed on the support structure 3, and the in-place proximity switch 7 is used to detect whether there is a differential 4 on the placement structure 1.

[0124] In this example, if the in-place proximity switch 7 detects that there is a differential 4 on the placement structure 1, an in-place signal is generated, and the in-place signal is displayed through a pre-set in-place light bulb, or the in-place signal is sent to a pre-set controller.

[0125] In a preferred embodiment, the in-place proximity switch 7 is connected to the guide rod cylinder 21, and if the in-place proximity switch 7 detects that there is a differential 4 on the placement structure 1, a placement signal is generated and sent to the guide rod cylinder 21.

[0126] In this example, if the guide rod cylinder 21 determines that each of the in-place proximity switches 7 sends the placement signal, the guide rod cylinder 21 controls at least one of the top rods 22 to move towards at least one of the placement structures 1, and respectively contacts the differential 4 placed on the placement structure 1, thereby achieving the technical effect of automatically positioning the differential 4 according to the in-place situation of the differential 4 on the placement structure 1, and improving the positioning efficiency of the differential 4.

[0127] It should be noted that the first proximity switch 35, the second proximity switch 36, and the in-place proximity switch 7 in the present application are any one of an inductive (eddy current) proximity switch, a capacitive proximity switch, a Hall proximity switch, a photoelectric proximity switch, a pyroelectric proximity switch, an ultrasonic proximity switch, and a microwave proximity switch.

[0128] Inductive (eddy current) proximity switches use the eddy current generated in a conductive object when it is brought near a proximity switch that generates an electromagnetic field. The eddy current reacts to the proximity switch, causing a change in the internal circuit parameters of the switch, thereby identifying the presence or absence of a conductive object near the switch, and further controlling the on or off of the switch.

[0129] Capacitive proximity switches determine the position of an object by detecting a change in capacitance. The measuring head of the proximity switch is usually one plate of a capacitor, and the other plate is the housing of the switch or the object itself. When the object is moved towards the proximity switch, regardless of whether it is a conductor, its proximity will cause a change in the dielectric constant of the capacitor, and further cause a change in the capacitance, causing the state of the circuit connected to the measuring head to change, thereby controlling the on or off of the switch.

[0130] Hall-effect proximity switches are made based on the Hall effect, and the core component is a Hall element. When a magnetic object is moved near the Hall-effect switch, the Hall element generates a Hall effect, causing a change in the internal circuit state of the switch, thereby identifying the presence of a magnetic object near the switch, and further controlling the on or off of the switch.

[0131] Photoelectric proximity switches work using the photoelectric effect, and the light-emitting device and the photoelectric device are arranged in the same detection head in a certain direction. When there is a reflective surface (detected object) near the photoelectric proximity switch, the photoelectric device receives the reflected light, and the signal is output, thereby sensing the presence of an object.

[0132] Pyroelectric proximity switches are made using elements that can sense temperature changes, and can detect an object when an object with a different temperature from the environment is brought near.

[0133] Ultrasonic proximity switches work using the reflection principle of ultrasonic waves, and are suitable for detecting objects at a distance.

[0134] Microwave proximity switches work based on the Doppler effect of microwaves, and can detect the proximity and movement state of an object.

[0135] It should be noted that in this document, the term "comprise", "include" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements not only includes those elements, but also includes other elements not explicitly listed, or inherent to such a process, method, article or device. Without more limitations, the element defined by the statement "comprises a" does not exclude the presence of another identical element in the process, method, article or device that includes the element.

[0136] Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the application being indicated by the following claims.
