DETAILED DESCRIPTION

[0046] The following will provide a clear and complete description of the technical solutions in the embodiments of this application, in conjunction with the accompanying drawings. Obviously, the described embodiments represent only a portion of the embodiments of this application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. To further clarify the technical solutions and advantages of this application, the clamping system, etc., will be described in detail below, in conjunction with the accompanying drawings.

[0047] The phaser, a collective term for the camshaft position sensor and crankshaft position sensor, is part of the variable valve timing system. Typically installed at one end of the camshaft, it regulates the opening and closing timing of the valves. When installing the phaser bolts, the camshaft must be tightened. Failure to do so can result in inaccurate torque and affect the bolt preload. The challenge is how to simply and efficiently tighten the camshaft.

[0048] In this regard, the present application provides a clamping system, such as Figure 1 As shown, the clamping system includes a workbench 1, a clamping mechanism 2, an adjusting mechanism 3 and a driving mechanism 4; the workbench 1 includes a mounting surface 11, the adjusting mechanism 3 is mounted on the mounting surface 11, the clamping mechanism 2 is rotatably connected to the adjusting mechanism 3, the driving mechanism 4 is connected to the adjusting mechanism 3, and the adjusting mechanism 3 can adjust the position and / or rotation angle of the clamping mechanism 2 on the mounting surface 11 through the driving force provided by the driving mechanism 4; wherein, a clamping slot 221 is provided at the first end of the clamping mechanism 2.

[0049] The clamping system provided in the embodiment of the present application includes a clamping mechanism 2, one side of which is provided with a clamping slot 221. When the camshaft needs to be clamped, the phaser can be placed on the mounting surface 11 of the workbench 1, and the adjustment mechanism 3 is controlled by the drive mechanism 4 to adjust the position or rotation angle of the clamping mechanism 2 on the mounting surface 11, thereby allowing the camshaft of the phaser to move into the clamping slot 221, and the camshaft is clamped through the clamping slot 221. After the camshaft is clamped, the bolts on the camshaft can be tightened manually or by other tightening equipment. The entire clamping operation is simple and efficient, and can reduce the labor intensity of workers, which is conducive to the mass production of phasers. At the same time, due to the presence of the adjustment mechanism 3, the clamping mechanism 2 can be moved to multiple positions and rotated to different angles, thereby enabling the clamping operation of camshafts in multiple positions, improving the applicability of the device and making it efficient and convenient to use.

[0050] Optionally, the shape of the slot 221 may be adapted to the shape of the camshaft, and those skilled in the art may select and adjust the shape of the slot 221 according to actual needs.

[0051] It should be noted that the clamping system provided in the embodiments of this application can be used to clamp a camshaft in a phaser. It can also be applied to other scenarios requiring component clamping, and those skilled in the art can select the appropriate system based on actual needs. The embodiments of this application illustrate their adaptability in the context of a phaser camshaft clamp.

[0052] In one embodiment of the present application, Figure 1 As shown, the adjusting mechanism 3 may include a first guide rail 31, a second guide rail 32 and an adapter 33, and the driving mechanism 4 includes a first cylinder 41; the first guide rail 31 and the second guide rail 32 are parallel and arranged at an interval of 213, the first end of the clamping mechanism 2 is slidingly connected to the first guide rail 31, and the second end of the clamping mechanism 2 is slidingly connected to the second guide rail 32, and the first end is opposite to the second end; one end of the first cylinder 41 is fixed on the mounting surface 11, and the first cylinder 41 includes a first piston 411, the free end of the first piston 411 is rotatably connected to one end of the adapter 33, and the other end of the adapter 33 is connected to the clamping mechanism 2, wherein when the first piston 411 is in a retracted state, the axis of the clamping mechanism 2 is not perpendicular to the axis of the first piston 411.

[0053] In the clamping system provided in the embodiment of the present application, the two ends of the clamping mechanism 2 are respectively slidably connected to the first guide rail 31 and the second guide rail 32. The first cylinder 41 is located between the first guide rail 31 and the second guide rail 32, and is connected to the clamping mechanism 2 through the adapter 33. When the rotation angle of the clamping mechanism 2 needs to be adjusted, the first piston 411 in the first cylinder 41 can be controlled to extend and retract. When the first piston 411 is extending and retracting, the adapter 33 will rotate relative to the first piston 411, and drive the first and second ends of the clamping mechanism 2 to move, which is ultimately reflected in the rotation of the clamping mechanism 2 relative to the mounting surface 11. It should be noted that the first end of the first cylinder 41 is fixedly connected to the mounting surface 11, and the second end is connected to the adapter 33. When the first piston 411 is extended, Figure 1 Taking the perspective in as an example, the second end of the first cylinder 41 will rotate a certain angle counterclockwise relative to the first end. At this time, the clamping mechanism 2 will also rotate clockwise as a whole under the action of the first cylinder 41.

[0054] For example, Figure 1 , since the adapter 33 is fixedly connected to the clamping mechanism 2, the first end of the clamping mechanism 2 moves along the second guide rail 32 toward the first cylinder 41, while the second end of the clamping mechanism 2 moves along the second guide rail 32 away from the first cylinder 41. As a result, the clamping mechanism 2 as a whole rotates clockwise around the connection point between the adapter 33 and the first piston 411. The principle of rotation when the first piston 411 retracts inward is the same as in the above example and will not be elaborated on here.

[0055] It should be noted that when the first piston 411 is in the retracted state, which means that the first cylinder 41 is not in operation, the axis of the clamping mechanism 2 is not perpendicular to the axis of the first piston 411, that is, the axis of the clamping mechanism 2 is set at a certain angle to the axis of the first piston 411. At this time, the adapter 33 and the first piston 411 are also set at a certain angle. When the first piston 411 moves, it can force the adapter 33 to rotate relative to the first piston 411, thereby driving the clamping mechanism 2 to rotate.

[0056] Therefore, the clamping system provided in the embodiment of the present application can clamp the camshaft at least in two positions and facilitate the tightening of bolts.

[0057] by Figure 1 Taking the perspective shown as an example, the slot 221 of the clamping mechanism 2 is located on the right side. At this time, the slot 221 is at position 1. The camshaft can be sent to the designated position 1 by the machine, that is, sent into the slot 221, and then the bolt can be tightened.

[0058] Then, by controlling the first piston 411 in the first cylinder 41 to extend, the clamping mechanism 2 as a whole rotates clockwise. After rotation, the position of the clamping slot 221 is closer to the first cylinder 41 than in position 1. At this point, the clamping slot 221 is in position 2 (not shown). The camshaft can be mechanically moved to position 2, i.e., into the clamping slot 221, before the bolts are tightened. The first cylinder 41 is then controlled to cycle between positions 1 and 2.

[0059] It should be noted that the first cylinder 41 may be controlled so that the final landing point of the slot 221 is located between position 1 and position 2. The principle is the same as that of the above embodiment and will not be elaborated herein.

[0060] Therefore, by controlling the first cylinder 41, the rotation angle of the clamping mechanism 2 can be adjusted to facilitate clamping operations on the camshaft at multiple positions. It should be noted that the rotation angle of the clamping mechanism 2 refers to the degree to which the clamping mechanism 2 has rotated clockwise or counterclockwise relative to its initial state, centered around the connection point between the adapter 33 and the first piston 411.

[0061] Optionally, the first cylinder 41 and the adapter 33 may be an integrated structure. Exemplarily, the first cylinder 41 and the adapter 33 may be angle cylinders.

[0062] In one embodiment of the present application, the adjustment mechanism 3 may also include a first sliding component 30, which is slidingly connected to the first guide rail 31; the driving mechanism 4 also includes a second cylinder 42 fixed on the mounting surface 11, the second cylinder 42 is connected to the first sliding component 30, and can drive the first sliding component 30 to slide along the first guide rail 31; wherein, a groove 301 is opened on the side of the first sliding component 30, the opening direction of the groove 301 is toward the second cylinder 42, and the clamping mechanism 2 is passed through the groove 301.

[0063] It should be noted that after the clamping mechanism 2 clamps the camshaft, the torque required to tighten the bolts will be relatively high, and relying solely on the first cylinder 41 and the second guide rail 32 for limiting the position cannot meet the instantaneous torque required during the tightening process. For example, when the first piston 411 in the first cylinder 41 is extended, the clamping mechanism 2 as a whole moves clockwise, and the portion of the clamping mechanism 2 where the clamping groove is located to the left of the mounting surface 11. At this time, if the tightening operation is performed, the clamping mechanism 2 may be subjected to a force that forces it to rotate counterclockwise. If left untreated, the clamping mechanism 2 as a whole may shift or rotate, causing the tightening operation to fail.

[0064] Therefore, in this embodiment, a second cylinder 42 and a first sliding assembly 40 are provided. When the first piston 411 is extended, the second cylinder 42 drives the first sliding assembly 30 to move toward itself. Since the first sliding assembly 30 is provided with a groove 301, if the clamping mechanism 2 is forced to move counterclockwise under the action of the reaction force, it will abut against the side wall of the groove 301, that is, the groove 301 can limit the clamping mechanism 2, thereby ensuring the stability of the tightening.

[0065] It should also be noted that when the first piston 411 contracts, the clamping mechanism 2 moves counterclockwise as a whole. Since the first piston 411 has been retracted to its limit position, even if the clamping mechanism 2 is affected by the reaction force and has a tendency to rotate counterclockwise during the tightening operation, it cannot rotate further. Therefore, the clamping mechanism 2 can stably perform the clamping operation regardless of whether it is in position 1 or position 2.

[0066] In some embodiments, the first sliding assembly 30 includes a first slider 34, a second slider 35 and a connecting member 39; the first slider 34 and the second slider 35 are arranged at intervals and are respectively slidably connected to the first guide rail 31; the connecting member 39 is located on the side of the first slider 34 away from the mounting surface 11, and is respectively connected to the first slider 34 and the second slider 35, and a groove 301 is provided on the connecting member 39.

[0067] In the clamping system provided in the embodiment of the present application, to facilitate production and installation, a first slider 34 and a second slider 35 are connected to the first guide rail 31. A connecting member 39 is connected to the two sliders, and the aforementioned groove 301 is formed on the connecting member 39. Since the first guide rail 31 is relatively long, two sliders can be provided to ensure stable movement.

[0068] In one embodiment of the present application, the adjustment mechanism 3 also includes a third guide rail 36 and a third slider 37; the third guide rail 36 is parallel to the first guide rail 31 and is arranged at an interval of 213, and is arranged between the first guide rail 31 and the second guide rail 32, and the third slider 37 is slidably connected to the third guide rail 36 and is fixedly connected to the clamping mechanism 2.

[0069] It should be noted that after the clamping mechanism 2 clamps the camshaft, the torque when tightening the bolt will be relatively large, and relying solely on the first guide rail 31 and the second guide rail 32 to limit cannot meet the instantaneous torque of the tightening process.

[0070] Therefore, in the clamping system provided in the embodiment of the present application, a third guide rail 36 can be provided between the first guide rail 31 and the second guide rail 32. The clamping mechanism 2 is slidably connected to the third guide rail 36 via a third slider 37, and the third guide rail 36 is parallel to the first guide rail 31. This is equivalent to providing an additional support point between the first and second ends of the clamping mechanism 2. This provides a certain support force when tightening the phaser bolt to counteract the instantaneous torque during the tightening process, ensuring the reliability of the entire system. Furthermore, the sliding connection between the third slider 37 and the third guide rail 36 does not affect the position of the clamping mechanism 2.

[0071] Optionally, the third slider 37 is rotatably connected to the clamping mechanism 2 to avoid affecting the clamping mechanism 2 when it rotates.

[0072] In one embodiment of the present application, the adjustment mechanism 3 may further include a displacement base plate 38, which is respectively connected to the first guide rail 31, the second guide rail 32 and the third guide rail 36, and the displacement base plate 38 is also connected to the adapter 33; the clamping mechanism 2 is fixed on the surface of the displacement base plate 38 facing away from the mounting surface 11.

[0073] In the clamping system provided in the embodiment of the present application, a displacement base plate 38 is further provided, that is, the clamping mechanism 2 is not directly connected to the first guide rail 31, the second guide rail 32 and the third guide rail 36, but is indirectly connected to the three through the displacement base plate 38. The displacement base plate 38 itself has a certain rigidity, and can also prevent the key position of the entire clamping mechanism 2 (the connection between the clamping mechanism 2 and the three guide rails) from being deformed when the phaser bolt is tightened, thereby enhancing the stability of the system structure and effectively preventing the position dislocation caused by the displacement of the clamping mechanism 2.

[0074] Optionally, the size, thickness and shape of the displacement base plate 38 can be selected and adjusted by those skilled in the art according to actual needs.

[0075] In one embodiment of the present application, a fourth guide rail 381 and a fourth slider 382 are provided on the displacement base plate 38; the fourth slider 382 is slidingly connected to the fourth guide rail 381, the driving mechanism 4 is connected to the fourth slider 382, ​​and can drive the fourth slider 382 to move along the fourth guide rail 381; the clamping mechanism 2 is fixedly connected to the fourth slider 382; wherein, the extension direction of the fourth guide rail 381 intersects with the extension direction of the first guide rail 31.

[0076] In some embodiments, the driving mechanism 4 may include a third cylinder 43 , which is connected to the fourth slider 382 and can drive the fourth slider 382 to move along the extension direction of the fourth guide rail 381 .

[0077] It should be noted that when the phaser is placed on the working surface, the position is not necessarily exactly the same each time. Therefore, in order to improve the applicability of the entire clamping system, the clamping system needs to be able to clamp the camshaft in the phaser at different positions.

[0078] In this regard, in the clamping system provided in the embodiment of the present application, a fourth guide rail 381 and a fourth slider 382 may also be provided on the displacement base plate 38. The clamping mechanism 2 is slidably connected to the fourth guide rail 381 via the fourth slider 382, ​​that is, the position of the clamping mechanism 2 in the extension direction of the fourth guide rail 381 can be adjusted. By controlling the drive mechanism 4, the relative position of the clamping mechanism 2 in the extension direction of the fourth guide rail 381 can be adjusted. In conjunction with the first cylinder 41 and the second cylinder 42, the position of the clamping mechanism 2 can be adjusted in multiple directions, and the rotation angle of the clamping mechanism 2 can also be adjusted, thereby enabling the clamping operation of the camshaft in the phaser at different positions, thereby improving the applicability of the entire clamping system.

[0079] The above-mentioned positions 1 and 2 are used as examples.

[0080] When the camshaft at position 1 needs to be tightened, the first cylinder 41 forces the entire clamping mechanism 2 to rotate clockwise. The third cylinder 43 then controls the movement of the fourth slider 382, ​​driving the clamping mechanism 2 along the extension direction of the fourth guide rail 381. No other machine is required to deliver the camshaft into the clamping slot 221. Once the camshaft is in the designated position, the clamping mechanism 2 rotates and is then controlled to move along the fourth guide rail 381. After the clamping slot 221 on the clamping mechanism 2 is properly engaged with the camshaft, tightening can then begin.

[0081] When the camshaft at position 2 needs to be tightened, the first cylinder 41 forces the clamping mechanism 2 to rotate counterclockwise as a whole. The third cylinder 43 then controls the movement of the fourth slider 382, ​​driving the clamping mechanism 2 along the extension direction of the fourth guide rail 381. In this case, no other machine is required to move the camshaft into the slot. Once the camshaft is in the designated position, the clamping mechanism 2 rotates and is then controlled to move along the fourth guide rail 381. After the movement, the clamping slot 221 on the clamping mechanism 2 precisely engages the camshaft, allowing tightening to proceed.

[0082] In one embodiment of the present application, the clamping mechanism also includes a reaction force limiting mechanism 5, which is arranged on the mounting surface 11 and can apply a force to the first slider 34; wherein, when the clamping mechanism 2 is in a working state, the end having the slot 221 has a tendency to rotate toward the first direction, and the direction of the force is opposite to the first direction.

[0083] According to the above embodiment, after the clamping mechanism 2 clamps the camshaft, the instantaneous torque generated when tightening the bolt will be relatively large. If not handled, the clamping mechanism 2 may be misaligned. In the clamping system provided in the embodiment of the present application, a reaction force limiting mechanism 5 can also be provided. After the clamping mechanism 2 clamps the camshaft, the reaction force is applied to the clamping mechanism 2 in the opposite direction to the force generated when tightening the bolt. This force can counteract the instantaneous torque during the tightening process, thereby ensuring the reliability of the entire system, effectively preventing positional misalignment caused by displacement of the clamping mechanism 2, and increasing the stability of the entire system.

[0084] In one embodiment of the present application, the reaction force limiting mechanism 5 includes a fifth guide rail 51 and a fifth slider 52, and the driving mechanism 4 also includes a fourth cylinder 44; the fifth guide rail 51 is located on the side of the first guide rail 31 away from the first cylinder 41, and is arranged in a direction perpendicular to the extension direction of the first guide rail 31, and the fifth slider 52 is slidingly connected to the fifth guide rail 51; the fourth cylinder 44 is fixed on the mounting surface 11 and connected to the fifth slider 52, and can drive the fifth slider 52 to move along the fifth guide rail 51.

[0085] In the clamping system provided in the embodiment of the present application, the fifth slider 52 is driven to move by the fourth cylinder 44. After the clamping mechanism 2 clamps the camshaft, the fifth slider 52 can be moved to a position against the first slider 34 and maintain the position unchanged. At this time, the first slider 34 has a tendency to move in a direction away from the first cylinder 41 when the bolt is tightened. The fifth slider 52 can limit the first slider 34, that is, it can give the first slider 34 a reverse force, and can resist the instantaneous torque during the tightening process, thereby ensuring the rigidity of the entire system during the tightening process and ensuring the reliability of the system torque.

[0086] In one embodiment of the present application, the reaction force limiting mechanism 5 also includes a limit block 53, which is connected to the fifth slider 52; wherein, the limit block 53 has a first inclined surface on the side facing the first guide rail 31, and the first slider 34 has a second inclined surface on the side facing away from the second slider 35, and the shapes of the first inclined surface and the second inclined surface are adapted to each other.

[0087] It should be noted that the fifth slider 52 is directly connected to the fourth cylinder 44. Since the instantaneous torque during the bolt tightening process is relatively low, if the reaction force acts directly on the fifth slider 52, the torque applied to the connection between the fifth slider 52 and the fourth cylinder 44 will also be relatively large, and the connection may be damaged.

[0088] In the clamping system provided in the embodiment of the present application, a limit block 53 is also provided, that is, an indirect component is provided between the first slider 34 and the fifth slider 52. The fifth slider 52 applies a force to the limit block 53, and the limit block 53 then applies a force to the first slider 34 to offset the instantaneous torque when the bolt is tightened. In addition, inclined surfaces are provided on both the limit block 53 and the first slider 34, wherein the first inclined surface and the second inclined surface are parallel and both are inclined so that the closer they are to the first cylinder 41, the closer they are to the first guide rail 31. By providing the first and second inclined surfaces, a force perpendicular to the inclined surfaces can be generated. This force is opposite in direction to the force applied to the clamping mechanism 2 during the bolt tightening process, which can better offset the force and ensure the stability of the entire system.

[0089] In some embodiments, the axis of the fourth cylinder 44 is perpendicular to the first guide rail 31 , and the direction of the driving force of the fourth cylinder 44 is also perpendicular to the first guide rail 31 .

[0090] In one embodiment of the present application, the clamping mechanism 2 may include a clamping member 21 and a clamping member 22; the clamping member 21 is respectively connected to the adjusting mechanism 3 and the driving mechanism 4, and a first clamping portion 211 and a second clamping portion 212 are provided on one side of the clamping member 21, and a gap 213 is provided between the first clamping portion 211 and the second clamping portion 212, and the driving mechanism 4 is used to drive the first clamping portion 211 and the second clamping portion 212 to move toward or away from each other; one end of the clamping member 22 is installed in the gap 213, and the other end is provided with a clamping slot 221.

[0091] In the clamping system provided in the embodiment of the present application, the distance 213 between the first clamping portion 211 and the second clamping portion 212 on the clamping member 21 is adjustable, that is, it can adapt to different types of clamping members 22. When the clamping member 22 needs to be replaced or installed and removed, the first clamping portion 211 and the second clamping portion 212 can be controlled by the drive mechanism 4 to easily and quickly replace them, thereby improving the applicability of the clamping system. In addition, the clamping member 22 can also be clamped and fixed when clamping is required.

[0092] Alternatively, the clamping member 22 may be a wrench. Those skilled in the art may select and adjust the type of wrench according to the type and size of the camshaft.

[0093] Finally, the entire workflow of the clamping system provided in the embodiment of the present application is described.

[0094] For example, the clamping system can clamp the camshaft at position 1 and position 2 on the mounting surface.

[0095] All equipment starts working, at this time the first cylinder 41 is in the initial state (ie retracted state), the clamping mechanism 2 is tilted, the state is as follows Figure 1 The state shown in . The second cylinder 42 controls the first sliding assembly 30 to move toward itself, and the fourth cylinder 44 controls the fifth slider 52 to move, forcing the limit block 53 to abut against the inclined surface on the connecting member 39. The third cylinder 43 then controls the clamping mechanism 2 to move along the extension direction of the fourth guide rail 381 in the direction away from the second guide rail 32, and clamps it with the camshaft at position 1, and then performs the bolt tightening operation. After the tightening is completed, the fourth cylinder 44 controls the fifth slider 52 and the limit block 53 to move in the opposite direction, and the second cylinder 42 controls the first sliding assembly 30 to move away from itself to complete the unlocking. Finally, the third cylinder 43 controls the clamping mechanism 2 to move in the opposite direction along the fourth guide rail 381 and return to the initial position.

[0096] The first piston of the first cylinder 41 is controlled to extend, causing the clamping mechanism 2 to rotate clockwise as a whole. After the rotation, the second cylinder 42 controls the first sliding assembly 30 to move toward itself, and the fourth cylinder 44 controls the fifth slider 52 to move, forcing the stop block 53 to abut against the inclined surface of the connecting member 39. The third cylinder 43 then controls the clamping mechanism 2 to move away from the second guide rail 32 along the extension direction of the fourth guide rail 381, clamping it with the camshaft at position 2. The bolt is then tightened. After tightening is completed, the fourth cylinder 44 controls the fifth slider 52 and the stop block 53 to move in the opposite direction. The second cylinder 42 then controls the first sliding assembly 30 to move away from itself, completing the unlocking process. Finally, the third cylinder 43 controls the clamping mechanism 2 to move in the opposite direction along the fourth guide rail 381, returning to its initial position.

[0097] For the remaining equipment, replace the camshafts whose bolts are not tightened, and repeat the above operations using the clamping system provided in the embodiment of the present application.
