Description

Technical Field

[0001] The present invention belongs to the technical field of the installation of engine oil control valves, and specifically relates to an auxiliary device for installing an engine oil control valve. Background Art

[0002] As an actuator of an engine variable phase regulator, the oil control valve needs to achieve fast and accurate action responses, and the action responses are ensured by the lubricating oil pressure in the oil circuit;

[0003] Currently, there is a lack of special installation tools during the assembly process of the engine oil control valve. Most of the time, the staff holds the oil control valve by hand and then installs the oil control valve into the oil control valve installation hole on the camshaft cover. During this process, due to the instability of manual operation, during the docking and installation of the oil control valve, the surface of the oil control valve hole is often scratched due to the instability of the oil control valve, resulting in lubricating oil leakage. This not only affects the fast action response of the oil control valve but also causes oil stains on the engine surface. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects in the prior art that there is a lack of installation tools for the oil control valve, and most of them are assembled by hand-held manually. The manual hand-held assembly operation is unstable, resulting in easy scratching of the surface of the oil control valve hole, causing lubricating oil leakage, which not only affects the fast action response of the oil control valve but also causes oil stains on the engine surface. The present invention provides an auxiliary device for installing an engine oil control valve. By setting this device, it can provide a guiding function for the installation of the oil control valve, facilitate the installation of the oil control valve, and at the same time ensure the stability and accuracy of the installation of the oil control valve, ensuring the quality of the oil control valve after installation. And this device uses the existing structure of the camshaft cover for positioning without causing structural changes to the camshaft cover.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An auxiliary device for installing an engine oil control valve, comprising a cover plate, a support assembly and a guide sleeve. Among them, the support assembly is installed below the cover plate and is used to fix the cover plate above the engine camshaft cover. The guide sleeve is arranged on the side of the cover plate and is connected to the cover plate through a support arm, and is used to provide a guiding effect for the installation of the oil control valve. The guide sleeve is composed of a fixed sleeve installed at one end of the support arm and a movable sleeve movably connected to the fixed sleeve. Both the fixed sleeve and the movable sleeve adopt a semi-circular structure. The fixed sleeve and the movable sleeve are connected end to end to form a closed circular ring structure. The inner side of the ring structure formed by the fixed sleeve and the movable sleeve adopts a narrowing funnel structure with a gradually decreasing inner diameter from top to bottom. By setting this device, it can provide a guiding effect for the installation of the oil control valve and facilitate the installation of the oil control valve. When this device is in use, first, the cover plate is fixedly installed above the engine camshaft cover through the support assembly. After the fixation is completed, the position of the guide sleeve is outside the installation hole of the oil control valve. At this time, the circular ring structure formed by the combination of the fixed sleeve and the movable sleeve encloses the outside of the installation hole of the oil control valve. Then, the oil control valve is directly installed into the installation hole of the oil control valve through the guidance of the fixed sleeve and the movable sleeve. After the installation is completed, the movable sleeve is opened, and then the entire device is removed from the engine camshaft cover. The operation is convenient. Moreover, the inner side of the circular ring structure formed by the fixed sleeve and the movable sleeve in this device adopts a narrowing funnel structure with a gradually decreasing inner diameter from top to bottom, enabling it to better provide a guiding effect for the oil control valve (the oil control valve will gradually be centered and aligned during the insertion process into the installation hole of the oil control valve), further facilitating the installation of the oil control valve.

[0007] In a possible implementation manner, outwardly protruding structures are provided on the outer sides of both ends of the fixed sleeve and the movable sleeve. The protruding structure at one connection end of the fixed sleeve and the movable sleeve is movably connected through a connecting buckle, and the protruding structure at the other connection end is connected through a movable buckle. Both the movable buckle and the connecting buckle are inserted and connected to the protruding structure through an insertion shaft. The insertion shaft connecting the movable buckle to the protruding structure on the fixed sleeve is detachable. After removing this insertion shaft, the movable buckle can be opened by flipping. When the movable buckle is opened, the movable sleeve can rotate and open with the insertion shaft on the connecting buckle as the axis. This can ensure that after the installation of the oil control valve is completed, the guide sleeve can be opened and removed from the oil control valve (if the fixed sleeve and the movable sleeve are fixedly connected, it will block the disassembly of the guide sleeve after the installation of the oil control valve).

[0008] In a possible implementation, the support arm is connected to the cover plate via a clamp, one side of the clamp has an opening of a "U"-shaped structure, one end of the support arm is mounted on the inner side of the U-shaped structure of the clamp, the other side of the clamp has an opening of a "匚"-shaped structure, and both ends of the "匚"-shaped structure on the clamp are evenly bent inwardly, a clamping groove is provided at the edges of the upper and lower surfaces of the cover plate, the "匚"-shaped structure of the clamp is clamped on the edge of the cover plate, and the "匚"-shaped structure on the clamp is The extension structures at both ends of the "-shaped structure are respectively in the clamping grooves on the upper and lower surfaces of the cover plate. The clamping piece is inserted with a locking bolt for locking and positioning the clamping piece. When the locking bolt is tightened, the position of the clamping piece on the cover plate is locked and fixed. Such a structural arrangement enables the clamping piece to slide and adjust its position along the length direction of the cover plate when the locking bolt is loosened, so that the position of the guide sleeve can be adjusted by sliding the clamping piece, so that the device can be suitable for the installation and use of engine camshaft covers of different models.

[0009] The camshaft is an axially rotatable member formed in a manner that allows the camshaft to be rotatably connected to the support arm and to the support arm when the camshaft is rotatably connected.

[0010] In one possible implementation, the support assembly includes two support columns, which are detachably mounted below the cover plate and perpendicular to the cover plate. The two support columns are respectively inserted into the ignition coil mounting hole and the bolt through hole of the engine camshaft cover to fix the cover plate. Therefore, the device uses the existing structure of the camshaft cover for positioning without causing structural changes to the camshaft cover.

[0011] In a possible implementation, an assembly screw is installed at the top of the support column, and a plurality of installation screw holes adapted to the assembly screw are provided on the upper surface of the cover plate. The assembly screw is screwed and installed in one of the installation screw holes, which facilitates the disassembly of the device when it is not in use, is beneficial for storage, and at the same time, the positions of the two support columns can be adjusted according to actual installation needs to meet the use of different engine camshaft covers.

[0012] In a possible implementation, a positioning disk is sleeved on the support column. The positioning disk is used to control the partial length of the support column inserted under the engine camshaft cover, so that the cover plate is fixed at a set height. The positioning disk can slide and adjust its position on the support column. Therefore, when the device is dealing with oil control valves at different height positions, it can adjust the height of the whole device (i.e., the height of the guide sleeve) to make it adapt to the installation position of the oil control valve, improving the applicability of the device.

[0013] In a possible implementation, a positioning mechanism is further included for positioning the position of the positioning disk. The positioning mechanism includes a sleeve, a slot body and a toothed plate. Among them, the sleeve is sleeved on the support column and fixedly connected to the positioning disk. The slot body is arranged on the outer wall of the support column along the length direction of the support column. The inside of the slot body has a toothed groove structure arranged in the vertical direction. The toothed plate is movably clamped inside the slot body. A positioning screw rod is screwed and inserted outside the sleeve. The positioning screw rod is a threaded rod. One end of the positioning screw rod passes through the sleeve and is rotatably connected to the toothed plate, so that when the positioning screw rod rotates, it can push the teeth on the toothed plate to engage with the toothed groove structure inside the slot body. When the positioning screw rod rotates, the positioning screw rod can drive the toothed plate to move. When the toothed plate moves and separates from the toothed groove structure inside the slot body, the sleeve and the positioning disk can slide and adjust their positions on the support column. On the contrary, when the toothed plate moves and engages with the toothed groove structure inside the slot body, the sleeve and the positioning disk are locked at the set position on the support column.

[0014] In a possible implementation, two groups of the positioning mechanisms are provided and symmetrically arranged outside the support column to ensure that the device can be fixed more stably.

[0015] In the present invention, by setting up this device, it can provide a guiding function for the installation of the oil control valve, facilitate the installation of the oil control valve, and at the same time can ensure the stability and accuracy of the installation of the oil control valve, guarantee the quality of the oil control valve after installation, and the device uses the existing structure of the camshaft cover for positioning without causing structural changes to the camshaft cover;

[0016] In the present invention, the guide sleeve is formed by combining a fixed sleeve and a movable sleeve with two semi-circular structures. It has an annular structure, and the inner side of the annular structure adopts a tapered funnel structure with a gradually decreasing inner diameter from top to bottom, enabling it to better guide the oil control valve. Moreover, the movable sleeve can be opened. Therefore, after the device completes the installation of the auxiliary oil control valve, the guide sleeve can be directly opened, and then the entire device can be removed from the engine camshaft cover, which is convenient to operate.

[0017] In the present invention, the positions of the two support columns, the position of the clamping member, the angle of the support arm, and the height of the adjustment positioning disk all adopt adjustable mounting structures. Therefore, when the device faces the specific structures of different engine camshaft covers, it can adjust itself to adapt to the engine camshaft cover, improving the applicability of the device.

Among them, the support assembly is installed below the cover plate 4 and is used to fix the cover plate 4 above the engine camshaft cover b. The guide sleeve 1 is arranged on the side of the cover plate 4 and is connected to the cover plate 4 through the support arm 2, and is used to provide a guiding function for the installation of the oil control valve.

[0032] By adopting the above technical solutions:

[0033] By setting this device, it can provide a guiding function for the installation of the oil control valve, facilitate the installation of the oil control valve.

[0034] Embodiment 2:

[0035] On the basis of Embodiment 1, in this embodiment, the guide sleeve 1 is composed of a fixed sleeve 12 installed at one end of the support arm 2 and a movable sleeve 14 movably connected to the fixed sleeve 12. Both the fixed sleeve 12 and the movable sleeve 14 adopt a semi-circular structure. The fixed sleeve 12 and the movable sleeve 14 are connected end to end to form a closed circular ring structure. The inner side of the ring structure formed by the fixed sleeve 12 and the movable sleeve 14 adopts a narrowing funnel structure with a gradually decreasing inner diameter from top to bottom.

[0036] By adopting the above technical solution:

[0037] When the device is in use, first, the cover plate 4 is fixedly installed above the engine camshaft cover b through the support assembly. After the fixation is completed, the position of the guide sleeve 1 is outside the oil control valve installation hole a. At this time, the ring structure formed by the combination of the fixed sleeve 12 and the movable sleeve 14 encloses the outside of the oil control valve installation hole a. Then, the oil control valve is directly installed into the oil control valve installation hole a through the guidance of the fixed sleeve 12 and the movable sleeve 14. After the installation is completed, the movable sleeve 14 is opened, and then the entire device is removed from the engine camshaft cover b. The operation is convenient. Moreover, the inner side of the ring structure formed by the fixed sleeve 12 and the movable sleeve 14 in this device adopts a narrowing funnel structure with a gradually decreasing inner diameter from top to bottom, enabling it to better provide a guiding function for the oil control valve (the oil control valve will gradually be centered and aligned during the insertion process into the oil control valve installation hole a), further facilitating the installation of the oil control valve.

[0038] Embodiment 3

[0039] On the basis of Embodiment 2, in this embodiment, outwardly protruding structures are provided on the outer sides of both ends of the fixed sleeve 12 and the movable sleeve 14. The protruding structure at one connection end of the fixed sleeve 12 and the movable sleeve 14 is movably connected through a connecting buckle 13, and the protruding structure at the other connection end is connected through a movable buckle 11. Both the movable buckle 11 and the connecting buckle 13 are inserted and combined with the protruding structure through an insertion shaft.

[0040] By adopting the above technical solution:

[0041] The insertion shaft connecting the movable buckle 11 and the protruding structure on the fixed sleeve 12 is detachable. After removing this insertion shaft, the movable buckle 11 can be opened by flipping. When the movable buckle 11 is opened, the movable sleeve 14 can rotate and open around the insertion shaft on the connecting buckle 13. This can ensure that after the installation of the oil control valve is completed, the guide sleeve 1 can be opened and removed from the oil control valve (if the fixed sleeve 12 and the movable sleeve 14 are fixedly connected, it will block the disassembly of the guide sleeve 1 after the installation of the oil control valve).

[0042] Embodiment 4

[0043] On the basis of Example 2, in this embodiment, the support arm 2 and the cover plate 4 are connected by a clamping member 5, one side of the clamping member 5 has an opening of a "U"-shaped structure, one end of the support arm 2 is installed on the inner side of the U-shaped structure of the clamping member 5, and the other side of the clamping member 5 has an opening of a "匚"-shaped structure, and the two ends of the "匚"-shaped structure on the clamping member 5 are evenly bent inwardly. A clamping groove 41 is provided at the edges of the upper and lower surfaces of the cover plate 4, and the "匚"-shaped structure of the clamping member 5 is clamped on the edge of the cover plate 4. The extension structures at both ends of the "匚"-shaped structure on the clamping member 5 are respectively in the clamping grooves 41 on the upper and lower surfaces of the cover plate 4. A locking bolt for locking and positioning the position of the clamping member 5 is inserted on the clamping member 5, and when the locking bolt is tightened, the position of the clamping member 5 on the cover plate 4 is locked and fixed.

[0044] A pin shaft 54 ​​is installed on one side of the clamping part 5, and the pin shaft 54 ​​is inserted into the support arm 2, so that the support arm 2 and the clamping part 5 are rotatably connected through the pin shaft 54, and a matching screw sleeve 52 is nested on the other side of the clamping part 5, and a locking rotary rod 51 is screwed and sleeved in the matching screw sleeve 52. The locking rotary rod 51 adopts a threaded structure, and a groove is provided on one side of the support arm 2, and a locking brake pad 53 is provided inside the groove. One end of the locking rotary rod 51 is pressed on the locking brake pad 53, and the contact surface between the locking brake pad 53 and the groove is rough, so that when the locking rotary rod 51 presses the locking brake pad 53, the locking brake pad 53 can generate friction with the contact surface of the groove to prevent the support arm 2 from rotating.

[0045] By adopting the above technical solution:

[0046] In the device, when the locking bolt is loosened, the clamping member 5 can slide along the length direction of the cover plate 4 to adjust the position, so that the position of the guide sleeve 1 can be adjusted by sliding the clamping member 5, so that the device can be suitable for the installation and use of engine camshaft covers b of different models;

[0047] When the locking rod 51 rotates so that the friction force between the locking brake pad 53 and the groove contact surface is smaller than the restraining force applied to the support arm 2 from the outside, the support arm 2 can be rotated around the pin shaft 54 ​​to adjust the angle so that it can meet the alignment of the oil control valve mounting hole a on the engine camshaft cover b. This can also be suitable for use with engine camshaft covers b of different models.

[0048] Example 5

[0049] On the basis of Example 2, in this embodiment, the support assembly includes two support columns 3, which are detachably installed under the cover plate 4 and perpendicular to the cover plate 4. The two support columns 3 are respectively inserted into the ignition coil mounting hole d and the bolt through hole c of the engine camshaft cover b to fix the cover plate 4.

[0050] The top of the support column 3 is provided with an assembly screw 35, and a plurality of installation screw holes 42 adapted to the assembly screw 35 are opened on the upper surface of the cover plate 4. The assembly screw 35 is screwed and installed in one of the installation screw holes 42, which is convenient for disassembling the device when it is not in use, facilitating storage. At the same time, the positions of the two support columns 3 can be adjusted according to actual installation needs to meet the use of different engine camshaft covers b.

[0051] A positioning disk 32 is sleeved on the support column 3. The positioning disk 32 is used to control the partial length of the support column 3 inserted under the engine camshaft cover b, so that the cover plate 4 is fixed at a set height. The positioning disk 32 can slide and adjust its position on the support column 3.

[0052] By adopting the above technical solutions:

[0053] This device uses the existing structure of the camshaft cover for positioning without causing structural changes to the camshaft cover. When dealing with oil control valves at different height positions, the height of the entire device (i.e., the height of the guide sleeve 1) can be adjusted to adapt to the installation position of the oil control valve, improving the applicability of this device.

[0054] Embodiment 6

[0055] On the basis of Embodiment 5, in this embodiment, a positioning mechanism is further included for positioning the position of the positioning disk 32. The positioning mechanism includes a sleeve 34, a groove body 31 and a groove body 31. Among them, the sleeve 34 is sleeved on the support column 3 and fixedly connected to the positioning disk 32. The groove body 31 is opened on the outer wall of the support column 3 along the length direction of the support column 3. The inside of the groove body 31 has a tooth groove structure arranged in the vertical direction. The toothed plate 36 is movably clamped inside the groove body 31. A positioning screw rod 33 is screwed and inserted outside the sleeve 34. The positioning screw rod 33 is a threaded rod. One end of the positioning screw rod 33 passes through the sleeve 34 and is rotatably connected to the toothed plate 36, so that when the positioning screw rod 33 rotates, it can push the teeth on the toothed plate 36 to engage with the tooth groove structure inside the groove body 31.

[0056] In a possible implementation manner, two groups of positioning mechanisms are provided, which are symmetrically arranged on the outside of the support column 3 respectively, ensuring that the device can be fixed more stably.

[0057] By adopting the above technical solutions:

[0058] When the positioning screw rod 33 rotates, the positioning screw rod 33 can drive the toothed plate 36 to move. When the toothed plate 36 moves and separates from the tooth groove structure inside the groove body 31, the sleeve 34 and the positioning disk 32 can slide and adjust their positions on the support column 3. On the contrary, when the toothed plate 36 moves and engages with the tooth groove structure inside the groove body 31, the sleeve 34 and the positioning disk 32 are locked at the set position on the support column 3.

[0059] Combined with Embodiment 1 - Embodiment 6, combined with Figure 1-9 As shown in the figure, the working principle of the present application is as follows:

According to the position of the oil control valve mounting hole a, by sliding the horizontal position of the clamping member 5, rotating the angle of the adjusting support arm 2, and adjusting the height of the positioning disc 32, make the guide sleeve 1 located directly above the oil control valve mounting hole a, and then install the oil control valve into the oil control valve mounting hole a through the guidance of the guide sleeve 1. After the installation is completed, open the guide sleeve 1 and remove the device, which is convenient and fast to operate.
