Detailed Implementation

[0018] In related technologies, spring mechanisms or tooling chuck deformation with interference fit to the inner diameter of the oil distribution plate are used to achieve picking and pressing. However, due to the dimensional tolerances of the parts, this method is prone to unstable clamping, incomplete picking, or the chuck getting stuck after pressing, affecting stability and production efficiency.

[0019] To address the aforementioned problems, this utility model provides an oil distribution plate installation fixture. By incorporating an elastic suction cup at the lower end of the press-fit fixture base, the suction cup generates negative pressure through elastic deformation upon contact with the oil distribution plate surface, achieving reliable adsorption. This method is not dependent on inner diameter accuracy, has strong adaptability, effectively avoids pick-up failures and jamming, and improves operational stability and efficiency.

[0024] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0026] The following describes in detail the overall structure, working principle, and technical effects of the oil distribution plate installation fixture provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0027] Please see Figures 1 to 4 This utility model provides a distribution plate installation fixture 10, which is applied in the field of distribution plate processing and production technology. The distribution plate installation fixture 10 is used to perform stable and reliable picking and pressing operations on the distribution plate parts 30 on automated or semi-automatic assembly lines, so as to solve the problems of unstable picking and jamming caused by part dimensional tolerances in traditional methods.

[0028] The oil distribution plate mounting fixture 10 includes a pickup assembly 100, which comprises a pressing fixture base 110 and an elastic suction cup 130. The pressing fixture base 110 connects to the press head of the press, transmitting the downward pressing force of the press and ensuring the alignment and stability of the fixture as a whole during operation. The elastic suction cup 130 is mounted at the lower end of the pressing fixture base 110 and undergoes elastic deformation to create negative pressure upon contact with the surface of the oil distribution plate component 30, thereby adsorbing and picking up the oil distribution plate component 30.

[0029] During operation, the press fixture 110 drives the elastic suction cup 130 downward under the press drive, so that it contacts and adsorbs the oil distribution plate part 30 placed at the loading position; then, the press fixture 110 moves down as a whole under the control of the press, accurately pressing the oil distribution plate part 30 into the corresponding positioning hole of the housing part 50.

[0030] Because the oil distribution plate and the positioning hole have an interference fit, when the press retracts after pressing, the suction force maintained by the elastic suction cup 130 is less than the pressing force required for the interference fit. Therefore, the suction cup and the part are disengaged first, thus achieving smooth separation of the tooling and the part, completing one pressing operation. Subsequently, the pressing tooling seat 110 returns to its initial standby position after the stroke resets, ready to enter the next work cycle.

[0031] This invention provides an oil distribution plate installation fixture 10. An elastic suction cup 130 is installed at the lower end of the press-fit fixture base 110. When the suction cup 130 contacts the surface of the oil distribution plate, it generates elastic deformation to create negative pressure, achieving reliable adsorption. This method is not dependent on inner diameter accuracy, has strong adaptability, effectively avoids pickup failures and jamming, and improves operational stability and efficiency.

[0032] In an optional embodiment, the oil distribution plate mounting fixture 10 further includes a loading component 300, which is used to transport the oil distribution plate parts 30 to a pick-up position directly below the press-fit fixture base 110, so as to achieve collaborative operation with the pick-up component 100 and improve the automation level and work efficiency of the overall assembly process.

[0033] Specifically, the feeding assembly 300 includes a rotating device and a carrier connected thereto. Through rotational motion, it sequentially transfers multiple oil distribution plate parts 30 to a designated station below the pressing fixture 110. When the carrier reaches the target position, the rotation stops, ensuring that the oil distribution plate parts 30 are accurately positioned directly below the elastic suction cup 130 and remain stable and stationary, waiting for the pressing fixture 110 to drive the elastic suction cup 130 downward to complete the contact and adsorption.

[0034] After the picking action is completed, the carrier immediately starts to rotate, rotating the carrier back to its original position from the pressing area, avoiding the space path required by the pressing fixture 110 for subsequent downward pressing, and avoiding interference with the tooling or assembled parts in the pressing movement.

[0035] Please refer to it again. Figure 1 The pickup assembly 100 also includes a fastener 150 for connecting the pressing fixture 110 to the press head of the press to ensure the reliability of the connection between the fixture and the press during pickup, transfer and pressing, and to prevent loosening or displacement due to vibration or uneven force.

[0036] Optionally, the fastener 150 is a connecting bolt. When connecting bolts are used, the number of them can be set to multiple (e.g., 2 or 4), and they are evenly distributed around the connection between the press fixture 110 and the press to form a symmetrical layout, thereby improving the overall connection rigidity.

[0037] In an optional embodiment, the press-fit fixture 110 is provided with a mounting hole 113, and the elastic suction cup 130 is inserted into the mounting hole 113 by interference fit to achieve a firm connection between the elastic suction cup 130 and the press-fit fixture 110.

[0038] Specifically, the mounting hole 113 is located on the lower end face of the press-fit fixture 110, with its axis extending vertically to accommodate the main body of the elastic suction cup 130. By designing an appropriate interference fit, the elastic suction cup 130 undergoes slight plastic deformation when pressed into the mounting hole 113, thereby forming a tight fit after assembly and effectively preventing loosening or detachment due to vibration or suction force reaction during use.

[0039] Furthermore, the press-fit fixture 110 has an inner cavity 111 that communicates with the mounting hole 113. That is, the inner cavity 111 is located above the mounting hole 113 and extends a certain depth along the axial direction of the press-fit fixture 110. The elastic suction cup 130 is provided with a limiting part 133, the radial dimension of which is larger than the diameter of the mounting hole 113. Thus, after the elastic suction cup 130 is assembled into the mounting hole 113, the limiting part 133 extends out of the mounting hole 113 and abuts against the cavity wall of the inner cavity 111.

[0040] Understandably, the abutting fit between the limiting part 133 and the cavity wall of the inner cavity 111 not only effectively limits the range of movement of the elastic suction cup 130 in the axial direction and prevents it from falling off during use, but also withstands the tensile load generated during picking, handling and pressing operations, preventing the elastic suction cup 130 from being pulled out of the tooling seat as a whole.

[0041] Please refer to it again. Figure 1 The bottom end of the elastic suction cup 130 is provided with an inwardly recessed adsorption working surface 131. This adsorption working surface 131 is the functional area where the elastic suction cup 130 directly contacts the surface of the oil distribution plate part 30. When the elastic suction cup 130 moves downward with the tooling and comes into contact with the surface of the oil distribution plate, the adsorption working surface 131 undergoes elastic deformation, gradually adhering to the surface of the part, gradually expelling the air between the contact interfaces, and forming a sealed cavity; a negative pressure is generated inside the cavity, and the stable adsorption of the oil distribution plate part 30 is achieved by relying on the pressure difference between atmospheric pressure and internal pressure.

[0042] Optionally, the adsorption working surface 131 is spherical, that is, part of a sphere. The spherical adsorption working surface 131 has good flexibility and self-adaptability. When there are slight flatness errors or warping on the surface of the oil distribution plate, or when the tooling is slightly tilted, it can still achieve uniform contact with the surface of the part through elastic deformation, effectively maintaining the sealing effect and reducing the risk of air leakage.

[0043] In this embodiment, the radius of curvature of the sphere can be adaptively designed according to the size, material properties, and required contact area of ​​the oil distribution plate to optimize adsorption performance. The specific radius of curvature is not limited and can be flexibly selected based on the actual application scenario.

[0044] In an optional embodiment, the elastic suction cup 130 is a rubber suction cup or a silicone suction cup. Silicone material has good aging resistance, temperature resistance and chemical stability, and is suitable for long-term operation in clean environments or high-temperature conditions; rubber (such as nitrile rubber, fluororubber, etc.) has high mechanical strength and wear resistance, and is more suitable for high-frequency and high-load operating conditions.

[0045] In addition, the elastic suction cup 130 can also be made of other flexible materials with excellent elasticity and sealing performance. The specific material selection can be determined according to the actual application requirements, and this embodiment does not make specific limitations in this regard.

[0046] Furthermore, the number of elastic suction cups 130 is at least two, and the at least two elastic suction cups 130 are distributed at the lower end of the press-fitting fixture 110 to adsorb different positions of the oil distribution plate part 30, so as to realize multi-point collaborative picking.

[0047] Optionally, multiple elastic suction cups 130 are arranged symmetrically. For example, three or four suction cups are set at equal intervals along the circumference with the central axis of the pressing fixture 110 as a reference, so as to ensure mechanical balance during the picking process and prevent the parts from deflecting or shaking during the handling process.

[0048] Taking the embodiment provided by this utility model as an example, the installation process of the oil distribution plate is as follows: During operation, the carrier of the feeding assembly 300 uses rotation to sequentially transfer multiple oil distribution plate parts 30 to a designated station below the pressing fixture 110. When the carrier reaches the target position, the rotation stops, ensuring that the oil distribution plate parts 30 are accurately positioned directly below the elastic suction cup 130 and remain stable and stationary, awaiting the pick-up operation.

[0049] Subsequently, the press fixture 110, driven by the press, moves the elastic suction cup 130 downward, bringing it into contact with the surface of the oil distribution plate part 30 located at the loading position. During the contact process, the adsorption working surface 131 of the elastic suction cup 130 undergoes elastic deformation, gradually adhering to the surface of the part and expelling interfacial air to form a sealed cavity. After the pressure is released, a negative pressure is generated inside the cavity, relying on the atmospheric pressure difference to achieve reliable adsorption of the oil distribution plate part 30.

[0050] After adsorption is complete and the part is firmly picked up, the carrier immediately starts to rotate, rotating the carrier back to its original position from the pressing area, avoiding the space path required for subsequent downward pressing of the pressing fixture 110, and avoiding motion interference.

[0051] Next, under the control of the press, the press fixture 110 continues to move downward as a whole, accurately guiding the oil distribution plate part 30, which has been adsorbed and fixed, into the corresponding positioning hole of the housing part 50, and completing the press fitting. Since the oil distribution plate and the positioning hole are interference fit, the pressing force required for their engagement is greater than the adsorption force that the elastic suction cup 130 can maintain. Therefore, when the press retracts after the press fitting is completed, the connection between the suction cup and the part is preferentially disengaged, thereby achieving smooth separation of the fixture from the assembled part.

[0052] Finally, the press-fitting fixture 110 returns to its initial standby position after its stroke resets, ready to enter the next work cycle.

[0053] In summary, this utility model provides an oil distribution plate installation fixture 10, which includes a pickup component 100, comprising a pressing fixture base 110 and an elastic suction cup 130. The pressing fixture base 110 connects to the press head of a press, transmitting the downward pressing force of the press and ensuring the alignment and stability of the fixture as a whole during operation. The elastic suction cup 130 is installed at the lower end of the pressing fixture base 110 and undergoes elastic deformation to generate negative pressure upon contact with the surface of the oil distribution plate part 30, thereby adsorbing and picking up the oil distribution plate part 30. Based on the above, this utility model, by setting an elastic suction cup 130 at the lower end of the pressing fixture base 110, utilizes the suction mechanism of negative pressure generated by contact deformation to complete the pickup operation. It is not dependent on the dimensional accuracy of the inner diameter of the oil distribution plate, has strong adaptability, and effectively avoids problems such as incomplete pickup, unstable clamping, or jamming after pressing caused by part tolerances, significantly improving the stability, success rate, and production efficiency of assembly operations.

[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
