[0001] This invention relates to the field of turbocharger assembly equipment technology, specifically a turbocharger impeller press-fitting device. Background Technology

[0002] As a core component of an engine that enhances power performance and reduces fuel consumption, the assembly precision of the turbocharger directly determines the overall efficiency and service life of the machine. In the turbocharger assembly process, the assembly of the intermediate inner bore retaining spring and the pressing of the impeller are key steps.

[0003] In existing technologies, these two processes are usually independent and require separate equipment and steps. The assembly of the retaining ring relies on manual operation of calipers, which is not only labor-intensive but also susceptible to deformation due to the instability of manual operation, making it difficult to accurately embed the retaining ring into the retaining groove of the intermediate body, resulting in low assembly accuracy. Furthermore, the separation of processes leads to a lengthy overall assembly flow, hindering production efficiency and failing to meet the demands of large-scale production. Summary of the Invention

[0009] Preferably, the outer wall of the outer cylinder is provided with an elongated hole communicating with its inner cavity, and a limiting pin is fixed on the outer wall of the inner cylinder, the limiting pin sliding with the inner cylinder within the elongated hole.

[0010] Preferably, the guide assembly includes a hinge seat and a guide seat, the hinge seat being fixedly installed on one side of the bottom of the upright plate, and the guide seat being fixed to the movable end of the hinge seat.

[0011] Preferably, the upper end of the guide seat is provided with a third guide cavity, and the lower end of the guide seat is provided with a fourth guide cavity coaxially connected to the third guide cavity.

[0012] Preferably, the hinged seat includes a first mounting plate and a second mounting plate hinged together by a pivot. The first mounting plate is fixed to the upright plate, and the guide seat is fixed to the second mounting plate.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Those skilled in the art will recognize that the invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples of it.

[0030] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the invention. It should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] like Figure 1 As shown, the turbocharger impeller pressing equipment includes a frame 1 and a pressing assembly 2. The frame 1 is equipped with a horizontally arranged conveying assembly 4 and a vertically arranged platform 6.

[0032] A vertical plate 10 is slidably connected to one side of the platform 6 via a vertically set first linear guide rail. A second cylinder 9 is fixed to the top of the platform 6, and the output end of the second cylinder 9 is fixedly connected to the vertical plate 10. The second cylinder 9 drives the vertical plate 10 to move rapidly along the Z-axis, causing the bottom pressing assembly 2 to quickly approach the tooling 5 on the conveying assembly 4, thus shortening the alignment time.

[0033] A slide block 7 is slidably connected to one side of the upright plate 10 via a vertically arranged second linear guide rail. A first cylinder 8 is fixed to the top of the upright plate 10, and the output end of the first cylinder 8 is fixedly connected to the slide block 7. The pressing assembly 2 is fixed to the bottom of the slide block 7, and a guide assembly 3 is installed on one side of the bottom of the upright plate 10, facing the pressing assembly 2. The first cylinder 8 drives the slide block 7 to move a short distance along the Z-axis, causing the pressing assembly 2 at the bottom to pass through the guide assembly 3 to perform pressing operations on the intermediate body 32 on the tooling 5.

[0034] like Figure 2 and Figure 3 As shown, the press assembly 2 has a three-layer coaxial structure, consisting of a press cylinder 26, an inner cylinder 24, and an outer cylinder 11 from the inside out.

[0035] The inner cylinder 24 is fixedly connected to the slide block 7 by the first locking bolt 18 and moves up and down with the slide block 7. The lower end of the inner cylinder 24 is provided with multiple circumferentially distributed inner flap claws 27 to adapt to the radial changes of the retaining spring 29 when it contracts: the radius of the retaining spring 29 gradually decreases during the contraction process, and the outer contour of the inner flap claws 27 can fit the inner wall of the retaining spring 29 to avoid deformation or displacement of the retaining spring 29, while guiding the retaining spring 29 to accurately enter the limiting groove of the intermediate body 32.

[0036] The outer cylinder 11 and the inner cylinder 24 are in a sliding fit, and can slide up and down axially relative to the inner cylinder 24 to release the clamping spring 29 at the end of the pressing process. The lower end of the outer cylinder 11 is provided with multiple circumferentially distributed outer flap claws 28 to provide driving force for the retraction of the clamping spring 29.

[0037] The outer cylinder 11 and the inner cylinder 24 are in sliding fit. Specifically, the upper end of the outer cylinder 11 is coaxially provided with a first guide seat 21 and a second guide seat 20, and the outer diameter of the second guide seat 20 is smaller than the outer diameter of the first guide seat 21, forming a stepped shaft structure. The lower end of the slide 7 is provided with a first guide cavity 16 that is adapted to the first guide seat 21, and the end face of the first guide cavity 16 is provided with a second guide cavity 17 that extends axially and is adapted to the second guide seat 20, forming a stepped guide cavity structure.

[0038] The second guide cavity 17 is equipped with a first spring 19, one end of which abuts against the second guide seat 20, and the other end abuts against the end face of the second guide cavity 17. After the pressing is completed, the first spring 19 releases its elastic force, pushing the outer cylinder 11 to move upward relative to the inner cylinder 24 to reset, preparing for the next loading of the retaining ring 29.

[0039] The outer wall of the outer cylinder 11 is provided with an elongated hole 14 that connects to its inner cavity. The outer wall of the inner cylinder 24 is fixed with a limiting pin 15. The limiting pin 15 slides in the elongated hole 14 along with the inner cylinder 24, limiting the maximum relative sliding distance between the inner cylinder 24 and the outer cylinder 11.

[0040] like Figure 2As shown, one side of the slide block 7 is provided with a threaded inner hole 22 that connects to the first guide cavity 16, ensuring that the set screw 23 can directly act on the first guide seat 21 after being screwed in, thereby constraining the outer cylinder 11 and preventing the outer cylinder 11 from sliding axially.

[0041] like Figure 4 and Figure 5 As shown, the end face of the outer flap claw 28 is provided with a slot 30, and a magnetic piece 31 is embedded in the end face of the slot 30. Multiple circumferentially distributed slots 30 together form an annular limiting space, constraining the retaining spring 29 to a preset position. The magnetic piece 31 is embedded in the end face of the slot 30, magnetically attracting the retaining spring 29 and preventing it from falling off. The inner flap claw 27 and the outer flap claw 28 are both relatively independent flap-shaped structures. These inner flap claws 27 and outer flap claws 28 together form a clamping head structure, conforming to the inner and outer surfaces of the retaining spring 29 from multiple angles, thus enabling the retaining spring 29 to retract.

[0042] like Figure 2 As shown, the guide assembly 3 includes a hinge seat 12 and a guide seat 13. The hinge seat 12 is fixed to one side of the bottom of the upright plate 10 and serves as a rotational support carrier for the guide seat 13. Its hinge axis is parallel to the axis of the press assembly 2.

[0043] like Figure 6 As shown, the upper end of the guide seat 13 is provided with a third guide cavity 34, the inner diameter of which is adapted to the maximum outer diameter (uncontracted state) of the outer flap claw 28, ensuring that the outer flap claw 28 can enter smoothly without radial clearance. The lower end of the guide seat 13 is provided with a fourth guide cavity 33 coaxially connected to the third guide cavity 34. The inner diameter of the fourth guide cavity 33 is smaller than the inner diameter of the third guide cavity 34, and the two cavities are transitioned by a conical surface.

[0044] The press-fitting process of the snap ring 29 is achieved through the coordinated action of multiple components.

[0045] First, the snap ring 29 is embedded in the clamp head structure formed by the inner flap claw 27 and the outer flap claw 28 to form a double fixation of "radial wrapping + axial magnetic attraction" to ensure that the snap ring 29 does not shift before operation.

[0046] The guide seat 13 rotates to the position directly below the pressing assembly 2 via the hinge seat 12, making the third guide cavity 34 coaxial with the pressing assembly 2, and then locking its position via the limiting component 39, providing a precise guiding channel for the pressing assembly 2 to descend and preventing subsequent operations from deviating.

[0047] Place the sealing cover into the inner cavity of the intermediate body 32, start the second cylinder 9, drive the vertical plate 10 downward, and drive the pressing assembly 2 to quickly approach the guide seat 13 until the pressing assembly 2 is aligned with the inlet of the third guide cavity 34.

[0048] Switch to the first cylinder 8, drive the slide 7 downward, and drive the press assembly through the guide seat 13 to begin the assembly operation of the intermediate body 32.

[0049] When the press-fit assembly 2 passes through the guide seat 13, since the inner diameter of the fourth guide cavity 33 is smaller than the maximum outer diameter of the outer flap claw 28 in its uncontracted state, the cavity wall generates a radial extrusion force on the circumferential outer flap claw 28, forcing the outer flap claw 28 to deform towards the center, and simultaneously applying a radial driving force to the retaining spring 29, causing the retaining spring 29 to retract to the preset size.

[0050] As the outer flap claw 28 penetrates deeper into the fourth guide cavity 33, the frictional force with the cavity wall exceeds the preload of the first spring 19, forcing the outer cylinder 11 to slide upward relative to the inner cylinder 24. At this time, the retaining ring 29 remains relatively fixed to the outer flap claw 28 under the dual fixation of "radial wrapping + axial magnetic attraction".

[0051] When the first cylinder 8 reaches the end of its stroke, the inner cylinder 24 extends into the inner cavity of the intermediate body 32, and the end face of the inner flap claw 27 contacts the sealing cover plate of the intermediate body 32, applying an axial load to the sealing cover plate to ensure that the sealing cover plate is installed in place. At the same time, the outer cylinder 11 retracts to its highest point relative to the inner cylinder 24, and the outer flap claw 28 disengages from the clamping spring 29. The clamping spring 29 loses its radial restraint force and, through its own elasticity, resets, increasing in diameter and precisely engaging in the pre-set limiting groove of the intermediate body 32, completing the assembly.

[0052] like Figure 8 As shown, the hinged base 12 includes a first mounting plate 37 and a second mounting plate 38 hinged together by a pivot. The first mounting plate 37 is rigidly fixed to one side of the bottom of the upright plate 10 by fasteners such as bolts, providing a stable support reference. The second mounting plate 38 serves as the movable end of the hinged base 12, with one end hinged to the first mounting plate 37 via a pivot (the axis of the pivot is parallel to the axis of the pressing assembly 2), allowing it to rotate freely around the pivot. A limiting component 39 is located between the first mounting plate 37 and the second mounting plate 38, directly acting on the relative rotational movement of the two plates, constraining the rotation angle, and ensuring that the guide seat 13 can accurately align with the pressing assembly 2 when rotated to the working position.

[0053] like Figure 9 As shown, the limiting assembly 39 includes a pressure cap 43 and a guide rod 44. A first sidewall and a second sidewall extend from both sides of the second mounting plate 38, forming a symmetrical support structure. An arc-shaped waist hole 40 is formed in the first sidewall, its curvature matching the rotation trajectory of the second mounting plate 38. One end of the arc-shaped waist hole 40 connects to a circular limiting hole 41, with a diameter slightly larger than the width of the arc-shaped waist hole 40, for final position locking. The guide rod 44 is fixed to the second sidewall, its axis aligned with the center of the limiting hole 41. The pressure cap 43 has a stepped shaft structure, one end passing through the limiting hole 41 and fitted onto the end of the guide rod 44. The width and depth of the outer wall annular groove 42 are adapted to the arc-shaped waist hole 40, allowing it to be embedded in the arc-shaped waist hole 40 to achieve sliding constraint. A second spring 45 is fitted onto the outside of the guide rod 44, with both ends abutting against the end face of the pressure cap 43 and the second sidewall, respectively, providing axial thrust to the pressure cap 43.

[0054] When the second mounting plate 38 rotates to the working position, the pressure cap 43 moves along the trajectory to the limiting hole 41. The second spring 45 releases the preload, pushing the pressure cap 43 towards the first side wall. The shaft of the pressure cap 43 fully enters the limiting hole 41, and the annular groove 42 disengages from the arc-shaped waist hole 40. At this time, the pressure cap 43 is radially constrained by the limiting hole 41, and the second mounting plate 38 cannot continue to rotate, achieving rigid locking.

[0055] like Figure 7 and Figure 10 As shown, the conveying assembly 4 is equipped with a cylinder lifting assembly 46, and a support plate 48 is fixed to the output end of the cylinder lifting assembly 46. A distance measuring sensor 47 is installed on the support plate 48. The sensing end of the distance measuring sensor 47 is lower than the lower end face of the impeller shaft and is coaxially aligned with the impeller shaft (after the tooling 5 is in place), ensuring that the axial movement of the impeller shaft can be accurately captured.

[0056] The pressure cylinder 26 is fixed inside the inner cylinder 24 by the second locking bolt 25. The bottom of the pressure cylinder 26 is provided with a pressure head 36 to realize the installation of the impeller 35.

[0057] The conveying component 4 drives the tooling 5 carrying the intermediate body 32 to be conveyed to the bottom of the pressing component 2. After the tooling 5 is in place, the cylinder lifting component 46 drives the pallet 48 to move upward, lifting the tooling 5 and the intermediate body 32 simultaneously.

[0058] Through mechanical and manual operation, the impeller is fitted onto the upper end of the impeller shaft. The first cylinder 8 drives the pressure cylinder 26 downward, and the pressure head 36 is fitted into the impeller shaft and contacts the end face of the impeller, applying an axial load to install the impeller in place.

[0059] The impeller and impeller shaft are interference-fitted. The axial load applied by the pressure head 36 is transmitted to the impeller shaft through the impeller, causing the impeller shaft to have a downward tendency, i.e., axial movement. The distance sensor 47 captures the axial movement distance of the impeller shaft in real time, completing the data acquisition of movement. This avoids damage to the workpiece (preventing the pressure head 36 from descending excessively, causing deformation of the impeller or impeller shaft) and also removes unqualified intermediate parts 32 (abnormal movement indicates failure of the limiting structure).

[0060] The embodiments described above are not exhaustive and do not limit the invention to specific implementations. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to effectively utilize the invention and its modifications. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
