Description

Technical Field

[0001] This utility model relates to the field of hydraulic tappet technology, and in particular to a double-top roller hydraulic tappet. Background Technology

[0002] The function of a tappet is to transmit the thrust of the camshaft to the pushrod (or valve stem) and to withstand the lateral force applied when the camshaft rotates. The tappet has an adjusting screw on its top to adjust the valve clearance, while a hydraulic tappet is a tappet driven by hydraulic pressure.

[0003] In existing technologies, roller hydraulic tappets are hydraulic tappets with rollers. However, existing roller hydraulic tappets are all set up separately, so they can only open or close one valve. They are single-aperture and cannot perform double-aperture. If double-aperture is required, two roller hydraulic tappets need to be combined. However, if two roller hydraulic tappets are combined, the position of the roller hydraulic tappets cannot be flexibly adjusted according to the position of the valve. Therefore, we propose a double-aperture roller hydraulic tappet. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies. Roller hydraulic tappets are hydraulic tappets with rollers. However, existing roller hydraulic tappets are all set up separately, so they can only open or close one valve. They are single-tapping types and cannot perform double tapping. If double tapping is required, two roller hydraulic tappets need to be combined together. However, if two roller hydraulic tappets are combined together, the position of the roller hydraulic tappets cannot be flexibly adjusted according to the position of the valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-top roller hydraulic tappet includes a first hydraulic tappet and a second hydraulic tappet. The second hydraulic tappet is located on the left side of the first hydraulic tappet. A fixing mechanism is snapped onto the periphery of the first hydraulic tappet, and an adjusting mechanism is snapped onto the periphery of the second hydraulic tappet. A mounting plate is fixedly connected to the bottom of the fixing mechanism and the adjusting mechanism. Lifting components are fixedly connected to both sides of the mounting plate, and a connecting component is fixedly connected to the opposite side of the lifting components.

[0007] The fixing mechanism includes a first arc-shaped clamping plate symmetrically installed around the first hydraulic tappet. A first electric push rod is fixedly connected to the opposite side of the first arc-shaped clamping plate. A first fixing seat is fixedly connected to the periphery of the fixed end of the first electric push rod, and the first fixing seat is fixedly connected to the mounting plate.

A second fixed seat is fixedly connected to the periphery of the fixed end of the second electric push rod. A moving component is fixedly connected to the bottom of the second fixed seat. A linear guide rail is correspondingly provided on the periphery of the moving component and on the top of the mounting plate. A power component is installed on the top of the mounting plate and on the left side of the linear guide rail.

[0009] As a preferred embodiment of this utility model, a first anti-slip pad is adhered to the inner side of the first arc-shaped card plate, and the first anti-slip pad is made of silicone material.

[0010] The technical effect of adopting the above-mentioned further solution is that by setting the first anti-slip pad, the first anti-slip pad can effectively improve the anti-slip performance of the first arc-shaped clamping plate, thereby effectively ensuring the clamping force on the first hydraulic tappet.

[0011] As a preferred embodiment of this utility model, a second anti-slip pad is adhered to the inner side of the second arc-shaped card plate, and the second anti-slip pad is made of silicone material.

[0013] As a preferred embodiment of this utility model, the power assembly includes a mounting groove formed on the mounting plate, a drive motor is fixedly connected inside the mounting groove, and the output end of the drive motor is fixedly connected to the lead screw.

[0014] The technical effect of adopting the above-mentioned further solution is that, through the setting of the power component, the drive motor in the power component can effectively provide power to the lead screw in the moving component, and the rotation of the lead screw can effectively drive the lead screw slider to move within the linear guide rail.

[0017] As a preferred embodiment of this utility model, an adjustment groove is provided through the center of the top of the mounting plate.

[0018] The technical advantage of adopting the above-mentioned further solution is that the adjustment groove facilitates the installation of the first hydraulic tappet and the second hydraulic tappet.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In this invention, through the setting of a fixing mechanism and an adjusting mechanism, the first electric push rod in the fixing mechanism can effectively control the position of the first arc-shaped clamping plate, thereby facilitating the clamping and releasing of the first hydraulic tappet and facilitating the limiting of the first hydraulic tappet. The power component in the adjusting mechanism can effectively provide power to the moving component, thereby facilitating the moving component to drive the second fixed seat to move, thereby adjusting the position between the first hydraulic tappet and the second hydraulic tappet, so as to adapt well to the position of the valve for flexible adjustment.

[0030] Example 1:

[0031] like Figures 1-4 As shown, this utility model provides a technical solution: a double-top roller hydraulic tappet, including a first hydraulic tappet 1 and a second hydraulic tappet 2.

The periphery of the moving component 404 and the top of the mounting plate 5 are respectively provided with a linear guide rail 405. The top of the mounting plate 5 and the left side of the linear guide rail 405 are installed with a power component 406, which can effectively provide power to the moving component 404.

[0032] Example 2:

[0033] like Figures 1-4 As shown, a first anti-slip pad 3011 is bonded to the inner side of the first arc-shaped card plate 301, and the first anti-slip pad 3011 is made of silicone material, which can increase the friction between the first arc-shaped card plate 301 and the first hydraulic tappet 1.

[0034] The inner side of the second arc-shaped plate 401 is bonded with a second anti-slip pad 4011, which is made of silicone material and can increase the friction between the second arc-shaped plate 401 and the second hydraulic tappet 2.

[0035] The moving component 404 includes a lead screw 4041 rotatably connected to the linear guide rail 405. The lead screw 4041 has a lead screw slider 4042 intersecting its outer threads.

After positioning, the position of the connecting component 7 is adjusted by the lifting component 6. After adjustment, the connecting component 7 is fixed by the fixing component, thereby completing the fixing of the mounting plate 5. After fixing, the first hydraulic tappet 1 is taken out and placed between the first arc-shaped clamping plates 301. Then, the first electric push rod 302 is controlled to push the first arc-shaped clamping plate 301, so that the first arc-shaped clamping plate 301 and the first anti-slip pad 3011 clamp and fix the first hydraulic tappet 1. After completion, the second hydraulic tappet 2 is taken out. The second hydraulic tappet 2 is placed between the second arc-shaped clamping plates 401, and then the second electric push rod 402 is controlled to push it, so that the second arc-shaped clamping plates 401 and the second anti-slip pad 4011 clamp the second hydraulic tappet 2. After clamping, the drive motor 4062 is turned on according to the position of the valve. After the drive motor 4062 is turned on, it will drive the lead screw 4041 to rotate. The rotating lead screw 4041 will drive the lead screw slider 4042 to move within the linear guide rail 405, thereby controlling the position of the second hydraulic tappet 2 to align with the valve. The drive motor 4062 is then stopped, and the adjustment is completed. This utility model, through its design, can effectively and flexibly adjust the position of the roller hydraulic tappet according to the position between the valves, which is very convenient.
