Description

Technical Field

[0001] This invention relates to the field of oil pump assembly technology, and in particular to a mechanical oil pump gear mounting device and mounting method. Background Technology

[0002] An oil pump is a lightweight and compact pump, and it comes in three main types: inline, distributor, and unit. An oil pump requires a power source to operate; its lower camshaft is driven by the engine crankshaft gear. When assembling the signal disc inside the oil pump, a wrench is needed to tighten it. However, during the tightening process, the gear usually rotates as well, thus preventing the application of torque.

[0003] Existing fixing methods mostly rely on manual auxiliary limiting or simple blocking structures, which make it difficult to achieve stable locking of gears in confined spaces. Furthermore, the gear sizes of different oil pump models vary, further increasing the difficulty of tooling.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanical oil pump gear mounting device and installation method. The device uses two sets of top frame plates that move relative to each other along the waist groove and are locked by the pressure teeth and pressure tooth grooves on the pressure plate. In conjunction with the telescopic adjustment of the movable cross frame in the side baffle within the main cross frame and the horizontal locking mechanism that engages and locks the horizontal locking tooth grooves on the side of the movable cross frame, the width and length of the annular structure formed by the support fixing plate, side baffle, rear baffle, and support bar can be flexibly adjusted according to the actual size of the oil pump gear.

[0006] To achieve the above objectives, the present invention provides a mechanical oil pump gear mounting device and mounting method, including a support fixing plate, side brackets, a rear stop bar, and a support bar. The support fixing plate is provided in two symmetrical sets, and a top frame plate is mounted on the top of each set of support fixing plates. The side brackets are positioned above the top frame plate along its length. The rear stop bar and the support bar are respectively positioned above the two ends of the two side brackets and perpendicular to the side brackets, so that the two side brackets, the rear stop bar, and the support bar form a closed annular structure.

[0007] A support plate is installed at the bottom of the support bar, and a tooling gear is installed above the support plate on the inner side of the annular structure. The two top frame plates can move inward to change the internal width of the annular structure, and the support bar can move along the length direction of the side baffle to change the internal length of the annular structure.

[0008] In one embodiment of the present invention, a plurality of studs are installed on the top of the support fixing plate, and a waist groove is provided on the upper surface of the top frame plate corresponding to the position of each stud. The stud passes through the waist groove and is fastened by a sleeve nut. When it is necessary to move the top frame plate to change the internal width of the annular structure, it is only necessary to loosen the nut. After moving it into place, the nut is tightened. The operation is convenient, simple and quick.

[0009] In one embodiment of the present invention, the upper surface of the top frame plate is provided with pressure tooth grooves along the length of the waist groove on both sides of the waist groove. A pressure plate is sleeved on the stud below the nut. The bottom of the pressure plate is provided with pressure teeth that can be adapted to the pressure tooth grooves. When the top frame plate moves into place and the nut is tightened, the pressure teeth can be locked in the pressure tooth grooves, so that the top frame plate is positioned and locked. This can greatly improve the stability of the top frame plate after it has moved.

[0010] In one embodiment of the present invention, the rear stop bar has mating longitudinal grooves on both sides along the moving direction of the top frame plate, and the side stop plate has a groove at the position of the rear stop bar. The two ends of the rear stop bar are clamped in the groove, and a protruding structure is provided in the groove corresponding to the position of the mating longitudinal groove. The protruding structure is slidably engaged in the mating longitudinal groove. The mating longitudinal groove ensures that the vertical relationship between the rear stop bar and the side stop plate is not affected when the top frame plate moves, and the rear stop bar will not disengage, thereby ensuring the pressing effect of the rear stop bar on the oil pump gear when tightening the signal plate later.

[0011] In one embodiment of the present invention, the side support frame includes a main crossbeam and a movable crossbeam, wherein the main crossbeam has a hole along its length at one end near the support bar, one end of the movable crossbeam is inserted into the hole, and the movable crossbeam is movable within the hole, the support bar is assembled at one end of the movable crossbeam, and when the movable crossbeam moves, the overall effective length of the side support frame changes, thereby realizing the lateral movement of the support bar.

[0012] In one embodiment of the present invention, a horizontal locking mechanism is installed on the outer side of the main cross frame near the support bar, and the movable cross frame can be locked by the horizontal locking mechanism.

[0013] In one embodiment of the present invention, a transverse locking tooth groove is provided on the outer side of the movable crossbeam along the length direction. The transverse locking mechanism includes a receiving part, and a movable plate with transverse locking teeth is installed inside the receiving part. The movable plate can move in a direction perpendicular to the side guard. A first cylinder is installed on the outside of one end of the receiving part. The piston rod of the first cylinder is connected to the movable plate. When the first cylinder is running, it can push the movable plate to move, so that the transverse locking teeth on the movable plate can be inserted into the corresponding transverse locking tooth groove on the side of the movable crossbeam, so that the movable crossbeam moves and is positioned laterally.

[0014] In one embodiment of the present invention, a limiting groove is formed along the length direction on the side of the support bar near the side baffle. The limiting groove has an L-shaped cross section. One end of the movable crossbeam is provided with a limiting end. The limiting end is slidably assembled in the limiting groove. When the top plate moves, the limiting end can slide in the limiting groove. Therefore, when the top plate moves, the perpendicular relationship between the support bar and the side baffle will not change, thereby ensuring the clamping effect of the subsequent tooling gear on the oil pump gear.

[0015] In one embodiment of the present invention, a support plate is installed on the top of the support plate, and a second cylinder is installed on the outer side of the support plate. The upper surface of the support plate is provided with a guide groove along the length direction within a closed annular structure. A slide block is slidably mounted above the guide groove via a guide plate. The tooling gear is detachably mounted on the slide block. After the device is adjusted laterally and longitudinally, the tooling gear is adjacent to the oil pump gear and is not locked. Activating the second cylinder will push the slide block to move towards the oil pump gear until the oil pump gear and the tooling gear are fully engaged. At this time, the oil pump gear is locked.

[0016] This application also discloses a method for installing a mechanical oil pump gear, the specific installation steps of which are as follows:

[0017] S1. Loosen the nuts to make the two top bracket plates movable. Move the two top bracket plates so that the distance between the side brackets above the two top bracket plates matches the size of the oil pump gear to be installed. Then tighten the nuts to fix the top bracket plates.

[0018] S2. Push the support bar to move it until the tooling gear on the pallet moves to a position close to the oil pump gear. Start the first cylinder to control the movement of the movable plate until the transverse locking teeth on the movable plate engage with the transverse locking tooth groove on the side of the movable cross frame. At this time, the movable cross frame is locked, that is, the position of the support bar is locked.

[0019] S3. Place the tooling gear within the annular structure formed by the two side stops, the rear stop, and the support bar;

[0020] S4. Start the second cylinder to push the slide block to move until the oil pump gear above the slide block is fully engaged with the tooling gear. At this time, the oil pump gear is locked.

[0021] Compared with the prior art, the mechanical oil pump gear installation device and method according to the present invention uses two sets of top frame plates that move relative to each other along the waist groove and are locked by the pressure teeth and pressure tooth grooves on the pressure plate. With the telescopic adjustment of the movable crossbeam in the side frame within the main crossbeam and the horizontal locking mechanism engaging and locking the horizontal locking tooth grooves on the side of the movable crossbeam, the width and length of the annular structure formed by the support fixing plate, side frame, rear stop rod, and support bar can be flexibly adjusted according to the actual size of the oil pump gear. At the same time, the longitudinal grooves on both sides of the rear stop rod slide with the protrusions on the side frame, and the limiting groove at the end of the support bar slides with the limiting end of the movable crossbeam, ensuring that all components are always vertical and stable without dislocation during the adjustment process. On this basis, the second cylinder pushes the slide to make the tooling gear fully mesh with the oil pump gear, thereby effectively locking the oil pump gear when the signal plate is tightened, completely solving the problem of gear rotation and inability to apply torque during the wrench tightening process.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The specific embodiments of the present invention will be described in detail, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0032] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0033] like Figure 1 - Figure 8 As shown, a mechanical oil pump gear mounting device according to a preferred embodiment of the present invention includes a support fixing plate 1, a side baffle 4, a rear baffle 3, and a support bar 6. The support fixing plate 1 is provided in two symmetrical sets, and a top frame plate 2 is installed on the top of each set of support fixing plates 1. The side baffle 4 is arranged above the top frame plate 2 along the length direction of the top frame plate 2. The rear baffle 3 and the support bar 6 are respectively arranged above the two ends of the two side baffles 4 and perpendicular to the side baffles 4, so that the two side baffles 4, the rear baffle 3, and the support bar 6 enclose a closed ring structure.

[0034] A support plate 7 is installed at the bottom of the support bar 6, and a tooling gear 9 is installed above the support plate 7 on the inner side of the annular structure. The two top frame plates 2 can move inward to change the width of the annular structure. The support bar 6 can move along the length direction of the side baffle 4 to change the length of the annular structure.

[0035] Specifically, such as Figure 1 - Figure 3As shown, in order to enable the two sets of top frame plates 2 to move inward and change the internal width of the annular structure, in this embodiment, multiple studs 10 are installed on the top of the support fixing plate 1. The upper surface of the top frame plate 2 is provided with a waist groove 20 corresponding to the position of each stud 10. After the stud 10 passes through the waist groove 20, it is fastened by the sleeve nut 11. Based on this, when it is necessary to move the top frame plate 2 to change the internal width of the annular structure, it is only necessary to loosen the nut 11. After moving it into place, the nut 11 is tightened. The operation is convenient, simple and quick.

[0036] Specifically, such as Figure 1 - Figure 4 As shown, in order to better lock the top plate 2 after it is moved into place and ensure the stability of the device when fixing the oil pump gear 8, in this embodiment, the upper surface of the top plate 2 is provided with pressure tooth grooves 21 along the length of the waist groove 20 on both sides of the waist groove 20. A pressure plate 12 is sleeved on the stud 10 below the nut 11. The bottom of the pressure plate 12 is provided with pressure teeth 120 that can be adapted to the pressure tooth grooves 21. Based on this, when the top plate 2 is moved into place and the nut 11 is tightened, the pressure teeth 120 can be locked on the pressure tooth grooves 21, so that the top plate 2 is positioned and locked. This can greatly improve the stability of the top plate 2 after it is moved.

[0037] Specifically, such as Figure 1 - Figure 4 As shown, in order to ensure the longitudinal stability of the rear stop bar 3 while cooperating with the movement of the top plate 2, in this embodiment, the two sides of the rear stop bar 3 are provided with mating longitudinal grooves 30 along the moving direction of the top plate 2, and the side stop 4 is provided with a groove at the position of the rear stop bar 3. The two ends of the rear stop bar 3 are clamped in the groove, and a protruding structure is provided in the groove corresponding to the position of the mating longitudinal groove 30. The protruding structure slides and engages in the mating longitudinal groove 30. Based on this, the setting of the mating longitudinal groove 30 can ensure that the vertical relationship between the rear stop bar 3 and the side stop 4 will not be affected when the top plate 2 moves, and the rear stop bar 3 will not disengage, thereby ensuring the pressing effect of the rear stop bar 3 on the oil pump gear 8 when tightening the signal plate later.

[0038] Specifically, such as Figure 1 - Figure 5 As shown, in order to achieve the lateral movement of the support bar 6 so that the tooling gear 9 mounted on the pallet 7 can approach or move away from the oil pump gear 8, in this embodiment, the side baffle 4 includes a main crossbeam 40 and a movable crossbeam 41. The main crossbeam 40 has a hole along its length at one end near the support bar 6, and one end of the movable crossbeam 41 is inserted into the hole and can move within the hole. The support bar 6 is assembled at one end of the movable crossbeam 41. Based on this, when the movable crossbeam 41 moves, the overall effective length of the side baffle 4 changes, thereby achieving the lateral movement of the support bar 6.

[0039] Specifically, such as Figure 1, Figure 2 and Figure 5 As shown, in order to lock the movable crossbeam 41 after it moves, and to ensure that the support bar 6 will not be forced to move backward during the tightening of the oil pump signal plate, which would cause difficulties in the installation process, in this embodiment, a cross-locking mechanism 5 is installed on the outer side of the main crossbeam 40 near the support bar 6. The movable crossbeam 41 can be locked by the cross-locking mechanism 5.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the movable crossbeam 41 has a transverse locking tooth groove 411 along its length on the outer side. The transverse locking mechanism 5 includes a receiving part 50, and a movable plate 52 with transverse locking teeth 53 is installed inside the receiving part 50. The movable plate 52 can move in a direction perpendicular to the side baffle 4. A first cylinder 51 is installed on the outside of one end of the receiving part 50. The piston rod of the first cylinder 51 is connected to the movable plate 52. Based on this, when the first cylinder 51 is running, it can push the movable plate 52 to move, so that the transverse locking teeth 53 on the movable plate 52 can be inserted into the corresponding transverse locking tooth groove 411 on the side of the movable crossbeam 41, so that the movable crossbeam 41 can move and be positioned laterally.

[0041] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, in order to enable the support bar 6 to move in coordination with the top plate 2, in this embodiment, a limiting groove 60 is provided along the length direction on the side of the support bar 6 near the side baffle 4. The cross-section of the limiting groove 60 is L-shaped. One end of the movable crossbeam 41 is provided with a limiting end 410. The limiting end 410 is slidably assembled in the limiting groove 60. Based on this, when the top plate 2 moves, the limiting end 410 can slide in the limiting groove 60. Therefore, when the top plate 2 moves, the vertical relationship between the support bar 6 and the side baffle 4 will not change, thereby ensuring the clamping effect of the subsequent tooling gear 9 on the oil pump gear 8.

[0042] Specifically, such as Figure 7 - Figure 8 As shown, in order to ensure that the tooling gear 9 can lock the oil pump gear 8 and ensure the subsequent tightening of the signal disc, in this embodiment, a support plate 73 is installed on the top of the support plate 7, and a second cylinder 74 is installed on the outer side of the support plate 73. The upper surface of the support plate 7 is provided with a guide groove 71 along the length direction in a closed annular structure. A slide block 72 is slidably mounted above the guide groove 71 via a guide plate 70. The tooling gear 9 is detachably mounted on the slide block 72. Based on this, after the device is adjusted in the horizontal and vertical directions, the tooling gear 9 is adjacent to the oil pump gear 8 and is not locked. Activating the second cylinder 74 can push the slide block 72 to move closer to the oil pump gear 8 until the oil pump gear 8 and the tooling gear 9 are fully meshed. At this time, the oil pump gear 8 is locked.

[0043] A method for installing a mechanical oil pump gear, applied to the aforementioned mechanical oil pump gear mounting device, includes the following specific installation steps:

[0044] S1. Loosen the nuts 11 to make the two top bracket plates 2 movable. Move the two top bracket plates 2 so that the spacing between the side brackets 4 above the two top bracket plates 2 matches the size of the oil pump gear 8 to be installed. Then tighten the nuts 11 to fix the top bracket plates 2.

[0045] S2. Push the support bar 6 to move it until the tooling gear 9 on the support plate 7 moves to a position close to the oil pump gear 8. Start the first cylinder 51 to control the movement of the movable plate 52 until the transverse locking tooth 53 on the movable plate 52 engages with the transverse locking tooth groove 411 on the side of the movable cross frame 41. At this time, the movable cross frame 41 is locked, that is, the position of the support bar 6 is locked.

[0046] S3. Place the tooling gear 9 within the annular structure formed by the two side stops 4, the rear stop 3, and the support bar 6.

[0047] S4. Start the second cylinder 74 to push the slide 72 to move until the oil pump gear 8 above the slide 72 is fully engaged with the tooling gear 9. At this time, the oil pump gear 8 is locked.
