Description

Technical Field

[0001] The present invention relates to an auxiliary installation device for a turbocharger and a method for installing a turbocharger. Background Art

[0002] Turbocharging technology is a technology for improving the intake capacity of an engine. The principle is to use the inertial force of the engine exhaust gas to drive the turbine of the turbocharger, and the turbine drives the coaxial impeller. The impeller pressurizes the inhaled ambient air and sends it into the cylinder. Since the air pressure and air density increase, the amount of fuel burned is correspondingly increased and thus the output power of the engine is increased.

[0003] In a vehicle applying turbocharging technology, a turbocharger needs to be additionally installed on the vehicle. In the prior art, the turbocharger is usually manually installed by workers on the production line. Since the turbocharger has a large volume and high weight, two or more workers need to cooperate to complete the installation of the turbocharger on the vehicle. This installation method results in low production efficiency and it is very laborious for workers to move and adjust the turbocharger during the installation process.

[0004] In view of this, it is necessary to specifically design a device for assisting workers to install a turbocharger on a vehicle to improve productivity. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide an auxiliary installation device for a turbocharger, which is simple to operate, can improve the installation efficiency of installing the turbocharger on a vehicle and save production costs.

[0006] The object of the present invention is solved by an auxiliary installation device for a turbocharger, which includes an adapter and a support device capable of horizontal movement. The adapter can be installed on the support device and has a fixing device for fixing the turbocharger on the adapter.

[0007] According to the present invention, the auxiliary installation device has a support device capable of horizontal movement and an adapter for fixing the turbocharger can be installed on the support device. Thus, with the aid of this auxiliary installation device, the turbocharger can be quickly transported to a predetermined position in a simple manner and the turbocharger can be reliably held during the installation process. Thereby, the process of installing the turbocharger on the vehicle is simplified and the production efficiency is improved.

[0008] According to an extended solution of the auxiliary installation device of the present invention, the support device has a vertically extending support frame and a sliding frame that is vertically movably mounted on the support frame, and the adapter can be mounted on the sliding frame. By providing the support frame and the sliding frame, the position of the turbocharger can be adjusted in the vertical direction.

[0009] According to an extended solution of the auxiliary installation device of the present invention, the sliding frame has a horizontally extending shaft receiving portion, and the adapter has a mounting shaft, and the mounting shaft of the adapter can be inserted into the shaft receiving portion of the sliding frame. Thereby, the installation of the adapter on the support device is achieved in a simple and reliable manner.

[0010] According to an extended solution of the auxiliary installation device of the present invention, the fixing device of the adapter includes a pre-fixing mechanism for pre-fixing the turbocharger on the adapter and a locking mechanism for locking the turbocharger on the adapter. By dividing the fixing device into a pre-fixing mechanism and a locking mechanism, the fixing process of the turbocharger on the adapter can be optimized, making the fixing of the turbocharger on the adapter easier and more reliable.

[0011] According to an extended solution of the auxiliary installation device of the present invention, the pre-fixing mechanism includes an outer pre-fixing element and an inner pre-fixing element. Both the outer pre-fixing element and the inner pre-fixing element are provided on the adapter housing of the adapter. A partial gap for accommodating the turbocharger is formed between the outer pre-fixing element and the inner pre-fixing element, and the inner pre-fixing element can move along the longitudinal direction of the adapter housing by means of a spring device. By providing the outer pre-fixing element and the inner pre-fixing element, the pre-fixing of the turbocharger on the adapter can be achieved in a simple manner.

[0012] Advantageously, one end side of the adapter housing is open and the other end side has a housing bottom. The outer pre-fixing element is provided on the edge of the open end side of the adapter housing, and the inner pre-fixing element is provided on the housing bottom by means of a spring device. According to one embodiment, the outer pre-fixing element can be integrally formed on the edge of the open end side of the adapter housing. Of course, it is also conceivable that the outer pre-fixing element is detachably mounted on the edge of the open end side of the adapter housing, whereby the corresponding outer pre-fixing element can be replaced for different models of turbochargers without replacing the entire adapter.

[0013] According to an extended solution of the auxiliary installation device of the present invention, the locking mechanism includes an operating component installed on the outer side of the bottom of the housing and a pressing component located inside the adapter housing for pressing the turbocharger. Advantageously, the operating component is installed on the bottom of the adapter housing via a mounting element. The operating component includes an operating rod, a connecting rod, and a push rod. The operating rod is pivotally supported on the mounting element by means of a pivot pin. The operating rod is articulated to the connecting rod by means of a sliding pin, and the connecting rod is articulated to the push rod. An arc-shaped groove is provided in the mounting element. The sliding pin is located in the arc-shaped groove and can move between a first end position and a second end position of the arc-shaped groove. A linear groove is also provided in the mounting element, and the push rod can linearly move in this linear groove.

[0014] Further advantageously, the pressing component includes a pressing rod, a fixed rod, and an actuating rod. The pressing rod has a first end and a second end. The first end of the pressing rod is configured as a free end for pressing the turbocharger. The second end of the pressing rod is pivotally connected to the fixed rod fixed on the mounting element. The pressing rod is pivotally connected to one end of the actuating rod at a position between the first end and the second end. The other end of the actuating rod is connected to the push rod of the operating component. Through this design solution, the turbocharger is fixed to the adapter in a simple manner. Specifically, when the sliding pin is located at the first end position in the arc-shaped groove, the push rod extends out of the linear groove and drives the pressing rod to rotate towards the turbocharger, so that the pressing rod presses the turbocharger against the adapter housing. When the sliding pin is located at the second end position in the arc-shaped groove, the push rod retracts, and the pressing rod rotates away from the turbocharger.

[0015] According to an extended solution of the auxiliary installation device of the present invention, the mounting element has a first mounting plate. The first mounting plate has a recess for accommodating a floating element. The floating element is held on the first mounting plate by a first bolt. A spring element is provided between the bolt head of the first bolt and the floating element. A pre-tightening force towards the recess of the first mounting plate is applied to the floating element through the spring element and makes the floating element abut against the end of the sliding pin protruding from the arc-shaped groove. A locking hole is also provided on the floating element, and the locking hole is aligned with the first end position of the arc-shaped groove. Thus, when the sliding pin is located at the first end position (i.e., when the pressing rod presses the turbocharger against the adapter housing), under the action of the spring pre-tightening force, the sliding pin can extend into the locking hole and make the floating element abut against the first mounting plate. Thus, the sliding pin cannot continue to move in the arc-shaped groove and thus the pressing rod reliably presses the turbocharger against the adapter housing.

[0016] According to an extension of the auxiliary mounting device of the present invention, an unlocking element is provided on the first mounting plate, by which the floating element can overcome the spring force and move toward the bolt head of the first bolt and thus disengage the sliding pin from the locking hole of the floating element. In this case, by means of the rotation of the operating rod, the sliding pin can be moved from the first end position of the arc groove to the second end position, thereby causing the clamping rod to leave the turbocharger. Advantageously, the floating element is additionally retained on the first mounting plate by a second bolt parallel to the first bolt. By providing two bolts, on the one hand, the floating element can be prevented from rotating around the first bolt, and on the other hand, the floating element can be effectively prevented from tilting relative to the bolt rod of the first bolt.

[0017] Preferably, the mounting element further comprises a second mounting plate, the sliding pin is arranged between the first mounting plate and the second mounting plate, and an arcuate groove is respectively arranged in the first mounting plate and the second mounting plate, and the two arcuate grooves are arranged opposite to each other. The sliding pin used for hingedly connecting the operating rod and the connecting rod is respectively embedded with one end thereof in the corresponding arcuate groove. In this way, the sliding pin can achieve smooth movement in the arcuate groove.

[0018] According to an extension of the auxiliary mounting device of the present invention, a height adjustment device for adjusting the vertical height of the sliding frame is provided on the support frame, and the height adjustment device has a rocker, which is connected to the sliding frame via a gear transmission device so as to convert the rotational movement of the rocker into the vertical movement of the sliding frame. Therefore, the vertical height of the sliding frame and thus the turbocharger on the support device can be adjusted in a simple manner.

[0019] According to an extended solution of the auxiliary installation device of the present invention, the support device includes a base that can move horizontally, a support frame is fixed on the base, the base has a base plate and rolling wheels are installed below the base plate. Preferably, the base plate has a first base plate section, a second base plate section, and a third base plate section. The first base plate section and the third base plate section are arranged in parallel, and the second base plate section connects the first base plate section and the third base plate section and is perpendicular to the first base plate section and the third base plate section. The support frame is installed on the first base plate section, and preferably the first base plate section has a length longer than that of the third base plate section. Advantageously, a first rolling wheel is provided in the free end region of the first base plate section, a second rolling wheel is provided in the transition region between the first base plate section and the second base plate section, a third rolling wheel is provided in the transition region between the second base plate section and the third base plate section, and a fourth rolling wheel is provided in the free end region of the third base plate section. Through the above arrangement of the rolling wheels, the base can stably support the support frame and at the same time provide a spacious standing space for the operator. Further advantageously, the first rolling wheel and the second rolling wheel are designed as universal wheels, while the third rolling wheel and the fourth rolling wheel are designed as directional wheels, thereby improving the horizontal movement of the support device and enabling flexible steering of the support device.

[0020] The present invention also claims a method for installing a turbocharger onto a vehicle by means of an auxiliary installation device, the method comprising the following steps:

[0021] - Installing the turbocharger onto the adapter of the auxiliary installation device;

[0022] - Installing the adapter together with the turbocharger onto the support device of the auxiliary installation device;

[0023] - The auxiliary installation device transporting the turbocharger to a predetermined position and adjusting the height and orientation of the turbocharger; and

[0024] - Separating the turbocharger from the adapter after the installation of the turbocharger on the vehicle is completed. Description of the Drawings

[0036] Figure 1 and Figure 2 Show overall schematic views of the auxiliary mounting device 1 for a turbocharger according to the present invention from different perspectives. With the aid of the auxiliary mounting device 1, a turbocharger (not shown) to be mounted on a vehicle can be transported to a predetermined position on the vehicle production line and the position and orientation of the turbocharger can be maintained during the mounting process.

[0037] The auxiliary mounting device 1 for a turbocharger includes a horizontally movable support device 2 and an adapter 3. The adapter 3 has a fixing device for fixing the turbocharger thereto and can be detachably mounted on the support device 2.

[0038] Figure 3 Shows a perspective view of the support device 2 of the auxiliary mounting device 1. The support device 2 includes a horizontally movable base 4, a vertically extending support frame 5 fixed to the base 4, and a sliding carriage 6 movably mounted vertically on the support frame 5. The sliding carriage 6 has a horizontally protruding shaft receiving portion for fixing the adapter 3 (not shown here), and this shaft receiving portion is configured as a hollow receiving shaft 7 here.

[0039] On the support frame 5, there is a height adjustment device 35 for adjusting the vertical height of the sliding frame 6. The height adjustment device 35 has a rocker 22, which is connected to the sliding frame 6 through a mechanical transmission device, such as a gear-rack transmission device, so as to be able to convert the rotational motion of the rocker 22 into the vertical motion of the sliding frame 6 along the support frame 5. Additionally, as Figure 3 It can also be seen that on the support device 2, for example, on the support frame 5 of the support device 2, there is a bracket 23, and the adapter 3 can be stored on the bracket 23 in the non-use state of the auxiliary installation device 1.

[0040] The movable base 4 has a preferably flat base plate 8 and rolling wheels 9 are installed below the base plate 8. In this embodiment, the base plate 8 is configured in a substantially L-shape and the base 4 has four rolling wheels 9. It is also conceivable that the base plate 8 is configured in other shapes and has other numbers of rolling wheels.

[0041] In Figure 4 a favorable arrangement of the four rolling wheels 9 of the base 4 is shown. As Figure 4 can be seen, the base plate 8 has a first base plate section 44, a second base plate section 45, and a third base plate section 46. The first base plate section 44 and the third base plate section 46 are arranged in parallel, and the second base plate section 45 connects the first base plate section 44 and the third base plate section 46 and is perpendicular to the first base plate section and the third base plate section. The support frame 5 is installed on the first base plate section 44, and preferably the first base plate section 44 has a length longer than that of the third base plate section 46. Advantageously, a first rolling wheel 9 is provided in the free end region of the first base plate section 44, a second rolling wheel 9 is provided in the transition region between the first base plate section 44 and the second base plate section 45, a third rolling wheel 9 is provided in the transition region between the second base plate section 45 and the third base plate section 46, and a fourth rolling wheel 9 is provided in the free end region of the third base plate section 46. Through the above arrangement of the rolling wheels 9, the base 4 can stably support the support frame 5 and at the same time provide a spacious standing space M for the operator. Further advantageously, the first rolling wheel and the second rolling wheel are designed as universal wheels, while the third rolling wheel and the fourth rolling wheel are designed as directional wheels, thereby being able to improve the horizontal movement of the support device 2 and at the same time achieve flexible steering of the support device 2.

[0042] Figures 5 to 7 Perspective views of the adapter 3 are shown from different angles. Figure 8 A schematic cross-sectional view of the adapter 3 is shown. Figure 9 An assembled view of the turbocharger 47 and the adapter 3 is shown.

[0043] As Figures 5 to 7It can be seen that the adapter 3 has a cylindrical adapter housing 10. The adapter housing 10 is open on one end side and has a housing bottom 11 on the other end side. In the present embodiment, the housing bottom 11 is configured as a separate circular plate. Of course, it is also feasible that the housing bottom 11 is integrally formed with the adapter housing 10. An outer pre-fixing element 12 is provided, preferably integrally formed, on the edge of the open end side of the adapter housing 10. The cross-section of the outer pre-fixing element 12 is configured in an L-shape and has a first section 13 and a second section 14 (for example, see Figure 8 ), the first section 13 extends further outward from the edge of the open end side of the adapter housing 10, and the second section 14 extends from the first section 13 at an angle towards the central axis of the adapter housing 10 (the central axis is parallel to the longitudinal direction L of the adapter 3), and the angle is 80 degrees to 100 degrees, preferably 90 degrees.

[0044] An inner pre-fixing element 15 is provided inside the adapter housing 10. The inner pre-fixing element 15 and the outer pre-fixing element 12 together constitute a pre-fixing mechanism for pre-fixing the turbocharger on the adapter. The inner pre-fixing element 15 is arranged on the housing bottom 11 of the adapter housing 10 by means of a spring device 16 and can move along the longitudinal direction L of the adapter 3. A gap is formed between the outer pre-fixing element 12 and the inner fixing element 15. When the turbocharger is installed on the adapter, a part of the turbocharger (for example, the flange of the exhaust gas outlet in Figure 9 ) extends into the gap and can be pre-clamped between the outer pre-fixing element 12 and the inner pre-fixing element 15 by means of the spring device 16. Preferably, the inner pre-fixing element 15 has a tongue 17 extending towards the second section 14 of the outer pre-fixing element 12. Thus, in the installed state, a part of the turbocharger is clamped between the second section 14 of the outer pre-fixing element 12 and the tongue 17 of the inner pre-fixing element. The outer pre-fixing element 12 extends over a partial circumferential length of the adapter housing 10. Preferably, the extension length of the outer pre-fixing element is one quarter to one half of the entire circumferential length of the adapter housing 10. Thereby, a part of the turbocharger can be simply pushed into the gap between the outer pre-fixing element 12 and the inner pre-fixing element 15 from the side where the outer pre-fixing element 12 is not provided.

[0045] The adapter 3 further includes a locking mechanism. By means of the locking mechanism, the turbocharger 47 can be locked on the adapter 3. The locking mechanism includes an operating component 20 installed on the outer side of the housing bottom 11 of the adapter housing 10 and a pressing component 21 for pressing the turbocharger. The locking mechanism and the pre-fixing mechanism together constitute a fixing device for fixing the turbocharger on the adapter.

[0046] In addition, an installation shaft 24 is provided on the adapter housing 10 of the adapter 3 (on the housing bottom 11 in this embodiment), and the installation shaft 24 can be inserted into the receiving shaft 7 of the sliding carriage 6 so as to realize the installation of the adapter 3 on the support device 2. The installation shaft 24 has a first locking pin 48 for locking the rotational movement of the installation shaft 24 relative to the receiving shaft 7. Preferably, the receiving shaft 7 is rotatably mounted on the sliding carriage 6 and has a second locking pin 49 for locking the rotational movement of the receiving shaft 7 relative to the sliding carriage 6 (see Figure 10 ).

[0047] Figure 11 A partial schematic view of the operating assembly 20 is shown. The operating assembly 20 is mounted on the housing bottom 11 of the adapter 3 via a mounting element 26. The operating assembly 20 includes an operating lever 25, a connecting rod 28, and a push rod 29. The operating lever 25 is pivotally supported on the mounting element 26 by means of a pivot pin 40 and has a free end for operation by an operator. The end of the operating lever 25 close to the adapter housing 10 is articulated to one end of the connecting rod 28 by means of a sliding pin 27, and the other end of the connecting rod 28 is articulated to the push rod 29. An arc-shaped groove 30 is provided in the mounting element 26, and the sliding pin 27 is located in the arc-shaped groove 30 and can move between a first end position and a second end position in the arc-shaped groove 30. A linear groove 31 is also provided in the mounting element 26, and the push rod 29 can perform a linear movement in the linear groove 31. Preferably, the linear groove 31 extends along the longitudinal axis L of the adapter housing.

[0048] Figure 12A schematic view of a locking mechanism including an operating assembly 20 and a clamping assembly 21 is shown. For clarity, the adapter housing 10 and a part of the mounting element 26 are hidden in this figure. The clamping assembly 21 is located inside the adapter housing 10 and includes a clamping rod 32, a fixed rod 33, and an actuating rod 34. The clamping rod 32 has a first end and a second end. The first end of the clamping rod 32 is configured to clamp the free end of the turbocharger, while the second end is pivotally connected to the fixed rod 33 fixed to the mounting element 26. Additionally, the clamping rod 32 is pivotally connected to one end of the actuating rod 34 by means of a pivot shaft 18 at a position between the first end and the second end. The other end of the actuating rod 34 is connected to the push rod 29 of the operating assembly 20. Thus, the push rod 29 of the operating assembly 20 can act on the actuating rod 34 of the clamping assembly 21, and consequently, the pivotal movement of the operating rod 25 can be transformed into the pivotal movement of the clamping rod 32 via the connecting rod 28, the push rod 29, and the actuating rod 34. Specifically, when the sliding pin 27 is located at the first end position in the arcuate groove 30, the push rod 29 extends from the linear groove 31 and drives the clamping rod 32 to rotate towards the turbocharger, so that the clamping rod 32 clamps the turbocharger onto the adapter housing 10. When the sliding pin 27 is located at the second end position in the arcuate groove 30, the push rod 29 retracts, and the clamping rod 32 rotates away from the turbocharger.

[0049] Figure 13 A partial detailed view of the mounting element 26 is shown. As Figure 13 can be seen, the mounting element 26 has a first mounting plate 36, and an arcuate groove 30 is provided in the first mounting plate 36. The sliding pin 27 for pivotally connecting the operating rod 25 and the connecting rod 28 is embedded in the arcuate groove 30. Advantageously, a floating element 41 is provided on the side of the first mounting plate 36 facing away from the operating rod 52. In this embodiment, the floating element 41 is configured as a circular plate, but other shapes of floating elements, such as oval or rectangular, etc., can also be contemplated.

[0050] The first mounting plate 36 has a recess for accommodating the floating element 41. The floating element 41 is held on the first mounting plate 36 by a first bolt 42, and a gap is formed between the floating element 41 and the bolt head of the first bolt 42 so as to allow the floating element 41 to move along the bolt shaft of the first bolt 42, wherein the longitudinal direction of the bolt shaft is perpendicular to the longitudinal direction L of the adapter housing. A spring element is provided between the bolt head of the first bolt 42 and the floating element 41, and a preload force is applied to the floating element 41 toward the first mounting plate 36 by the spring element, so that the floating element 41 abuts against the end of the sliding pin 27 protruding from the arc-shaped groove 30. In order to prevent the floating element 41 from rotating around the first bolt 42, the floating element 41 is additionally held on the first mounting plate 36 by a second bolt 43 parallel to the first bolt 42. By providing two bolts 42, 43, it is also possible to effectively prevent the floating element 41 from tilting relative to the bolt shaft of the first bolt 42.

[0051] In addition, a locking hole 38 is provided on the floating element 41, and the locking hole 38 is aligned with the first end position of the arc-shaped groove 30, so that when the sliding pin 27 is located at the first end position (that is, when the pressing rod 32 presses the turbocharger on the adapter housing), the sliding pin 27 can extend into the locking hole 38 under the action of the spring preload force and make the floating element 41 abut against the first mounting plate 36. As a result, the sliding pin 27 cannot continue to move in the arc-shaped groove 30 and thus the pressing rod 32 reliably presses the turbocharger on the adapter housing 10.

[0052] After the installation of the turbocharger on the vehicle is completed, in order to loosen the clamping rod 32 to separate the turbocharger from the adapter 3, an unlocking element 39 is provided on the first mounting plate 36. By operating the unlocking element 39, the floating element 41 can be moved toward the bolt head of the first bolt 42 against the spring force and thus the sliding pin 27 can be disengaged from the locking hole 38 of the floating element 41. In this case, by rotating the operating rod 25, the sliding pin 27 can be moved from the first end position of the arc-shaped groove 30 to the second end position, thereby separating the clamping rod 32 from the turbocharger.

[0053] Advantageously, if Figure 13 It can be seen that the mounting element 26 also has a second mounting plate 37, the operating rod 25, the connecting rod 28 and the push rod 29 (and thus the sliding pin 27) are all arranged between the first mounting plate 36 and the second mounting plate 37, and an arc groove 30 is respectively provided in the first mounting plate 36 and the second mounting plate 37, and the two arc grooves 30 are arranged opposite to each other. The sliding pin 27 for hingedly connecting the operating rod 25 and the connecting rod 28 is respectively embedded with one end thereof in the corresponding arc groove 30. In this way, the smooth movement of the sliding pin 27 in the arc groove 30 can be achieved.

[0054] The operation of installing a turbocharger onto a vehicle using the auxiliary installation device 1 according to the present invention is as follows:

[0055] In the first step, the turbocharger is installed onto the adapter 3 of the auxiliary installation device 1. Specifically, a part of the turbocharger (such as the flange of the exhaust gas outlet of the turbocharger) can be pushed into the gap between the outer pre - fixing element 12 and the inner pre - fixing element 15 of the adapter, and the turbocharger is pre - clamped between the outer pre - fixing element 12 and the inner pre - fixing element 15 by the pre - tightening force of the spring device 16. Subsequently, the operating rod 25 is moved from the initial second end position to the first end position, whereby the pressing rod 32 presses the turbocharger against the adapter housing 10.

[0056] Subsequently, in the second step, the adapter together with the turbocharger is installed onto the support device 2 of the auxiliary installation device 1. Here, for example, the mounting shaft 24 of the adapter is inserted into the receiving shaft 7 of the carriage 6 of the support device 2, and the relative position of the adapter 3 and the carriage 6 is locked using the first locking pin 48.

[0057] In the third step, the turbocharger is conveyed to a predetermined position (such as on a vehicle production line) by means of the auxiliary installation device 1 and the height and orientation of the turbocharger are adjusted. For example, by pushing the support device 2 of the auxiliary installation device 1, the movement of the auxiliary installation device 1 with the installed turbocharger is achieved. By operating the height adjustment device 35, the carriage 6 and thus the vertical height of the turbocharger are changed, and by rotating the adapter 3 around the receiving shaft 7 with the aid of the handle 51, the orientation of the turbocharger can be changed. After the turbocharger is adjusted to the target orientation, the relative rotational movement of the receiving shaft 7 and the carriage 6 can be locked by means of the second locking pin 49.

[0058] Finally, the assembly task of the turbocharger onto the vehicle is carried out, and after the installation of the turbocharger onto the vehicle is completed, the turbocharger is separated from the adapter 3. For example, in such a way that: by operating the unlocking element 39 on the first mounting plate 36, the sliding pin 27 is disengaged from the locking hole 38 of the floating element 41 and thus the movement of the sliding pin 27 in the arcuate groove 30 is unlocked. Subsequently, by means of the operating rod 25, the sliding pin 27 is moved from the first end position to the second end position, whereby the pressing rod 32 moves away from the turbocharger and thus the turbocharger installed on the vehicle can be separated from the adapter 3.

[0059] The above - described embodiments illustrate or describe possible embodiments of the present invention, but the present invention is not limited to the above - described embodiments. It should be noted here that various different combinations between individual embodiments are also feasible.

[0060] Finally, it should be noted that, for the sake of easy understanding of the structure of the auxiliary installation device 1 of the present invention, the support device 2 and the adapter 3 are shown in the drawings out of proportion and / or enlarged and / or reduced.
