TECHNICAL FIELD

[0001] The present application relates to the technical field of motor press-fitting equipment, in particular to a product press-fitting transition counterforce support optimization structure. BACKGROUND

[0002] New energy motors often involve press-fitting of main parts such as shafts, bearings, and sealing rings. The current press-fitting equipment is limited by the height space of the conveying line, and the counterforce support lifting stroke is generally about 300 mm. For some product structures with high support points, the counterforce support lifting stroke is too long, which causes interference between the counterforce support and the tray when the counterforce support is lowered to the lowest point, and the tray cannot be released. Or the counterforce support is lowered below the tray, and the counterforce support interferes with the ground. This causes the problem of low compatibility of the product. SUMMARY

[0003] The purpose of the present application is to overcome the problem of low compatibility of the existing press-fitting equipment, and to provide a product press-fitting transition counterforce support optimization structure, which has the advantage of better compatibility.

[0004] In order to achieve the above purpose, the present application provides a product press-fitting transition counterforce support optimization structure, comprising:

[0005] A counterforce support mechanism for vertical lifting, which is used for press-fitting of products, and the effective stroke meets the height space of the conveying line;

[0006] A floating support movably installed on a horizontal transition floating support mechanism to move into or out of the press-fitting position;

[0007] Wherein, when the floating support moves into the press-fitting position, the counterforce support mechanism lifts the floating support to continue moving in the lifting process, and resets after completing the press-fitting.

[0008] Preferably, the horizontal transition floating support mechanism comprises a sliding guide rail, a mounting plate, and a first air cylinder, wherein the sliding guide rail is fixed on the press-fitting equipment through the mounting plate slidably connected thereto, the first air cylinder is fixedly installed at one end of the mounting plate, and the other end is drivingly connected with the sliding guide rail.

[0009] Preferably, the horizontal transition floating support mechanism further comprises an oil-free bushing, which is sleeved outside the floating support and movably connected with the floating support.

[0010] Preferably, the other end of the sliding guide rail is fixed with the oil-free bushing, and under the driving of the first air cylinder, the sliding guide rail moves relative to the mounting plate, driving the floating support to move into or out of the press-fitting position.

[0011] Preferably, the floating support middle part is in clearance fit with the inner wall of the oil-free bushing, and the length of the floating support middle part is greater than the length of the oil-free bushing.

[0012] Preferably, the counterforce support mechanism comprises a counterforce support and a second cylinder, which is used to drive the counterforce support to rise for press fitting or to descend for resetting.

[0013] Preferably, the counterforce support mechanism further comprises a plug cylinder, which is used to keep the counterforce support from retracting during press fitting work.

[0014] Preferably, the counterforce support is matched with a support assembly on the press fitting device to realize the fixation of the moving track.

[0015] Preferably, the support assembly at least comprises a sleeve set on the counterforce support and a support rod for fixing the sleeve on the press fitting device.

[0016] Through the above technical solution, when the press fitting device is used to press fit a product with a high support point, the floating support is first pushed to the press fitting position by the first cylinder, then the counterforce support is driven to rise by the second cylinder, and continues to rise after touching the floating support until the press fitting is completed. Due to the addition of the floating support, the distance that the counterforce support mechanism originally needs to move is greatly reduced, which reduces the stroke of the counterforce support mechanism, so that the press fitting device can solve the problem of press fitting position exceeding the stroke, and the compatibility of the product is improved.

[0029] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in combination with the embodiments of the present application and the drawings. The embodiments listed in the present application are only some embodiments of the present application, and should not be considered as all embodiments.

Figure 3 is the overall structure diagram of the counterforce support mechanism according to an embodiment of the present application;

[0032] In combination with the drawings, a product press-fitting transition counterforce support optimization structure can include a counterforce support mechanism, a floating support 1 and a horizontal transition floating support mechanism.

[0033] The counterforce support mechanism only performs vertical lifting and realizes press-fitting of the product when rising, wherein the effective stroke of the counterforce support mechanism satisfies the height space of the conveying line body, so as to avoid interference with other parts during the lifting of the counterforce support mechanism. Specifically, when the counterforce support mechanism is lowered to the lowest stroke position, the upper end does not interfere with the tray, and the lower end of the counterforce support mechanism does not interfere with the ground.

[0034] The floating support 1 is movably mounted on the horizontal transition floating support mechanism, and can move into or out of the pressing position as driven by the horizontal transition floating support mechanism. When moving into the pressing position, the rising reaction support mechanism first touches the floating support 1 and lifts it up until the floating support 1 pushes the product to complete the pressing. After pressing is completed, the reaction support mechanism descends to its reset position, and the floating support 1 separates from the reaction support mechanism when it descends to a certain height, and also resets under the drive of the horizontal transition floating support mechanism.

[0035] Of course, when pressing conventional products, there is no need for the horizontal transition floating support mechanism to drive the floating support 1 into or press-fitting position. The pressing of the product can be completed solely by the action of the reaction support mechanism.

[0036] Due to the limited height space of the conveyor line, the maximum lifting stroke of the reaction support mechanism is restricted. If the product structure becomes complex and the pressing position is higher than the original maximum stroke position, the reaction support mechanism alone cannot meet the pressing requirements. This invention, while ensuring that the effective stroke of the reaction support mechanism meets the height space of the conveyor line, adds an additional floating support 1 to compensate for the insufficient stroke of the reaction support mechanism. The floating support 1 can move into or out of the pressing position as driven by the horizontal transition floating support mechanism. The addition of the floating support 1 significantly reduces the distance the reaction support mechanism originally needed to move, effectively reducing the required stroke of the reaction support mechanism. This allows the pressing equipment to handle pressing positions beyond its stroke, thus improving product compatibility.

[0037] The floating support 1 moves under the drive of the horizontal transition floating support mechanism. To make the technical solution of this invention easier for those skilled in the art to understand, this invention provides a specific embodiment of the horizontal transition floating support mechanism. For example... Figure 2 As shown, Figure 2 This is a schematic diagram of the overall structure of the horizontal transition floating support mechanism according to one embodiment of the invention.

[0038] exist Figure 2 In the middle, the horizontal transition floating support mechanism may include: sliding guide rail 2, mounting plate 3 and first cylinder 4.

[0039] The sliding guide rail 2 is fixed to the pressing equipment via a mounting plate 3 that is slidably connected to it. The first cylinder 4 is fixedly installed at one end of the mounting plate 3, and the other end is connected to the sliding guide rail 2 in a transmission manner. When the first cylinder 4 is driven, it pushes one end of the sliding guide rail 2 closer to or further away from the mounting plate 3. In addition, the mounting plate 3 is fixedly connected to the pressing equipment by bolts.

[0040] In order to ensure that when the first cylinder 4 pushes the sliding guide rail 2 to move, the floating support 1 can move horizontally accordingly, and that the floating support 1 can continue to rise after moving into the pressing position by the reaction force support mechanism until the pressing is completed.

[0041] In this embodiment of the invention, the other end of the sliding guide rail 2 is fixed to the oil-free bushing 5. When the first cylinder 4 pushes the sliding guide rail 2 to move, the oil-free bushing 5 moves along with the sliding guide rail 2, thereby causing the floating support 1 to move into or out of the pressing position. Specifically, when the floating support 1 moves into the pressing position, the first cylinder 4 pushes the piston rod out, pushing the sliding guide rail 2 towards the product location until the floating support 1 reaches the pressing position, at which point the first cylinder 4 stops operating; when the floating support 1 moves out of the pressing position, the first cylinder 4 pushes the piston rod back, pushing the sliding guide rail 2 away from the product location until the floating support 1 is completely moved out of the pressing position and reset, at which point the first cylinder 4 stops operating.

[0042] In this embodiment of the invention, the middle part of the floating support 1 is clearance-fitted with the inner wall of the oil-free bushing 5, and the length of the middle part of the floating support 1 is greater than the length of the oil-free bushing 5. Since the oil-free bushing 5 is fixed to the end of the sliding guide 2 and cannot move up and down, if the reaction support mechanism rises, it will first touch the floating support 1 and lift the floating support 1 to continue rising until the floating support 1 pushes the product to complete the pressing requirement. Therefore, the floating support 1 can at least move up and down within the oil-free bushing 5. Specifically, the outer diameter of the floating support 1 is clearance-fitted with the inner diameter of the oil-free bushing 5 so that the floating support 1 can move up and down within the oil-free bushing 5, thus compensating for the insufficient stroke of the reaction support mechanism. Similarly, to prevent the floating support 1 from being completely pushed out of the oil-free bushing 5, the dimensions of its two ends must be greater than the inner diameter of the oil-free bushing 5. Of course, if necessary, the two ends and the middle part of the floating support 1 can be detached to facilitate the separation of the floating support 1 from the oil-free bushing 5, thereby facilitating the replacement and disassembly of the floating support 1.

[0043] The reaction force support mechanism is the main power output during the press-fitting process. To make the technical solution of this invention easier for those skilled in the art to understand, this invention provides a specific embodiment of the reaction force support mechanism. For example... Figure 3 As shown, Figure 3 This is a schematic diagram of the overall structure of the reaction support mechanism according to one embodiment of the invention.

[0044] exist Figure 3 In the middle, the reaction support mechanism may include: reaction support 6 and second cylinder 7.

[0045] The reaction support 6 rises under the drive of the second cylinder 7 for pressing or falls for resetting. In this embodiment, the effective stroke of the reaction support 6 and the second cylinder 7 must meet the height space of the conveyor line to avoid interference with other parts during the lifting and lowering process of the reaction support mechanism.

[0046] Because the counterforce support 6 first touches the floating support 1 during the lifting process and lifts the floating support 1 to continue the lifting until the floating support 1 pushes the product to complete the press fitting, it is necessary to ensure that the moving track of the counterforce support 6 during the lifting process is collinear with the floating support 1, so that the floating support 1 can be stably lifted by the counterforce support 6.

[0047] In this embodiment of the present application, the counterforce support 6 cooperates with the support assembly on the press fitting device to realize the fixation of the moving track. Because the moving direction and track of the counterforce support 6 during the lifting process are limited by the support assembly, the moving track of the counterforce support 6 is collinear with the floating support 1, so that the floating support 1 can be stably lifted by the counterforce support 6.

[0048] In order to further illustrate how the support assembly limits the moving direction and track of the counterforce support 6 and to make the skilled person in the art more easily understand the technical solution of the present application, the present application provides a specific embodiment of the support assembly.

[0049] In this embodiment, the support assembly can include a sleeve 9 and a support rod 10.

[0050] The sleeve 9 is sleeved on the counterforce support 6. Because the sleeve 9 can always limit the moving direction and track of the counterforce support 6, the counterforce support 6 will not be out of the sleeve 9 during the lifting and lowering. The sleeve 9 is fixed on the press fitting device through a plurality of support rods 10 fixed on the press fitting device, so as to ensure the position of the sleeve 9 is fixed to limit the moving direction and track of the counterforce support 6.

[0051] In order to make the skilled person in the art more easily understand the technical solution of the present application and the press fitting device, the present application provides a specific embodiment of the press fitting device and the press fitting mechanism in the press fitting device. Figure 4 is a front view of the press fitting mechanism in the press fitting device according to the first embodiment of the present application; Figure 5 is a rear view of the press fitting mechanism in the press fitting device according to the first embodiment of the present application.

[0052] In this embodiment, a is a conveying line body, b is a counterforce support mechanism, c is a machine body of the press fitting device, d is a press head assembly, e is a lifting positioning, and f is a horizontal transition floating support mechanism.

[0053] Specifically, the counterforce support 6 moves upward to press the product, and the press head assembly d limits the upward movement of the product.

[0054] The conveying line body a is used for conveying products, plays a role of conveying products, and guarantees continuous feeding and discharging.

[0055] The lifting positioning e is used for positioning the position of the product, so as to guarantee the accurate pressing position.

[0056] The pressing equipment can meet the pressing requirements of the engine and the gearbox.

[0057] When the pressing equipment of the present application is used for pressing the product with high support point, the floating support 1 is first moved to the pressing station by the first cylinder 4, then the counterforce support 6 is driven to rise by the second cylinder 7, and continues to rise after touching the floating support 1 until the pressing is completed. Due to the addition of the floating support 1, the distance that the counterforce support mechanism originally needs to move is greatly reduced, which reduces the stroke that the counterforce support mechanism needs to move, so that the pressing equipment can solve the operation of the pressing position beyond the stroke, and the compatibility of the product is improved.

[0058] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited thereto. Within the technical concept of the present application, various simple modifications can be made to the technical solutions of the present application, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present application will not be described again for various possible combination manners. However, these simple modifications and combinations should also be considered as disclosed by the present application, and all belong to the protection scope of the present application.
