Description

Technical Field

[0001] This invention belongs to the technical field of gearbox manufacturing equipment. Specifically, this invention relates to a gearbox vent valve installation tool and a method for installing a gearbox vent valve. Background Technology

[0002] The transmission vent valve is a small component assembly on a car transmission. The vent valve is used to balance the internal air pressure of the transmission. The vent valve connects the internal air pressure of the transmission with the external atmospheric air pressure, thereby achieving air pressure balance and preventing a series of malfunctions such as oil leaks caused by excessive internal air pressure.

[0003] The transmission has mounting holes for the breather valve. Currently, installing the breather valve involves an operator manually aligning the valve with the mounting hole and then tapping it onto the transmission with a rubber mallet. This manual installation method is complex, time-consuming, and inefficient.

[0004] For example, patent document CN210500016U discloses an auxiliary tool for installing a breather plug in an automotive transmission, including a tool body. One end of the tool body is provided with a breather plug placement groove and a locking structure that communicates with the bottom end face of the breather plug placement groove to engage a bent breather plug. However, the technical solution disclosed in this patent document also fails to solve the aforementioned technical problem. Summary of the Invention

[0007] The locking mechanism includes a guide block, a locking element movably disposed on the guide block for contacting the vent valve, and a locking spring that applies an elastic force to the locking element. The guide block is connected to the outer casing.

[0008] Two locking mechanisms are provided, and the two locking mechanisms are distributed on both sides of the vent valve.

[0009] The guide block is provided with a positioning groove for embedding the vent valve and a first receiving groove for accommodating the locking element and the locking spring. The first receiving groove has an opening on the inner wall of the positioning groove for exposing the locking element.

[0010] The push rod cylinder is provided with a guide groove for accommodating the first push rod and the vent valve. The guide groove is an arc-shaped groove.

[0011] The first push rod is connected to the reset mechanism, which is mounted on the push rod cylinder.

[0012] The reset mechanism includes a first spring and a second spring. A pin is provided on the first push rod, with the pin located between the first spring and the second spring. A groove is provided on the push rod cylinder for the pin to be embedded.

[0013] The driving mechanism includes an electromagnet, which is positioned opposite to the first push rod.

[0014] A battery compartment is provided on the outer casing, and a battery is placed inside the battery compartment.

[0015] The present invention also provides a method for installing a transmission vent valve, using the aforementioned transmission vent valve installation tool, and including the following steps:

Detailed Implementation

[0024] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," and similar expressions used in this document are for illustrative purposes only.

[0026] In the following implementation, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent a sequential execution order, but are merely for the convenience of description.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figures 1 to 4 As shown, the present invention provides a gearbox vent valve installation tool, including a housing, a push rod cylinder 3 disposed on the housing for placing the vent valve, a locking mechanism disposed on the housing for fixing the vent valve, a first push rod 1 movably disposed on the push rod cylinder 3 for pushing the vent valve to move, and a drive mechanism disposed on the housing for controlling the movement of the first push rod 1.

[0029] Specifically, if Figures 1 to 4As shown, the push rod cylinder 3 is fixedly mounted on the outer casing. During use, the vent valve to be installed is placed on the push rod cylinder 3. A locking mechanism engages with the push rod cylinder 3 to position the vent valve and lock it in place. Without external force applied, the vent valve will not move and remains in the locked position. When the drive mechanism controls the first push rod 1 to move, the first push rod 1 contacts the vent valve and applies a thrust, pushing the vent valve to move. Continuous tapping of the vent valve repeatedly eventually installs it in the gearbox mounting position.

[0030] like Figures 1 to 4 As shown, the locking mechanism includes a guide block 9, a locking element 4 movably mounted on the guide block 9 for contacting the vent valve, and a locking spring that applies an elastic force to the locking element 4. The guide block 9 is connected to the outer casing. The push rod cylinder 3 and the guide block 9 are fixedly mounted inside the outer casing. The axis of the push rod cylinder 3 is parallel to a first direction. The guide block 9 has a positioning groove for embedding the vent valve and a first receiving groove for accommodating the locking element 4 and the locking spring. The first receiving groove forms an opening on the first inner wall surface of the positioning groove, allowing the locking element 4 to protrude. When the locking element 4 moves in the first receiving groove, its direction of movement is parallel to a second direction, which is perpendicular to the first direction. A portion of the locking element 4 is located in the first receiving groove, and another portion is located in the positioning groove. The locking element 4 and the second inner wall surface of the positioning groove are arranged opposite each other, forming a space between the locking element 4 and the second inner wall surface of the positioning groove for a portion of the vent valve to be embedded, thereby locking the vent valve and keeping it in the locked position. When the first push rod 1 pushes the vent valve to move, the locking element 4 moves under the pressure applied by the vent valve, compressing the locking spring. The locking element 4 can then move into the interior of the first receiving groove, allowing the vent valve to continue moving towards the outside of the housing and finally be installed on the gearbox.

[0031] like Figures 1 to 3 As shown, two locking mechanisms are provided, distributed on opposite sides of the vent valve, which can improve the reliability of the vent valve locking. In this embodiment, the locking element 4 is a spherical part, and the locking spring is a cylindrical helical spring and a compression spring, which is sandwiched between the locking element 4 and the inner wall of the first receiving groove. This locking mechanism has a simple structure, occupies little space, and is easy to arrange.

[0032] like Figures 1 to 4As shown, the push rod cylinder 3 is provided with a guide groove to accommodate the first push rod 1 and the vent valve. The guide groove is an arc-shaped groove, and the axis of the guide groove is also the axis of the push rod cylinder 3. The push rod cylinder 3 is a cylinder with open ends and a hollow interior. The guide groove extends from one end face of the push rod cylinder 3 along the axis of the push rod cylinder 3 to the other end face of the push rod cylinder 3. The guide groove has an opening on the outer circular surface of the push rod cylinder 3, so that the vent valve can be embedded into the guide groove through the opening. The shape of the guide groove matches the shape of the vent valve. During the process of the vent valve being pushed, the push rod cylinder 3 can cooperate with the guide block 9 above to guide the vent valve, so that the vent valve can only move in a straight line, avoiding shaking, ensuring that the vent valve can be accurately installed on the gearbox, which helps to improve the assembly effect.

[0033] like Figures 1 to 4 As shown, the push rod cylinder 3 is fitted onto the first push rod 1, and the first push rod 1 is connected to the reset mechanism, which is located on the push rod cylinder 3. During the installation of the vent valve, the first push rod 1 needs to strike the vent valve multiple times. Therefore, the first push rod 1 needs to reciprocate. After the drive mechanism pushes the first push rod 1 a set distance each time, the reset mechanism applies a reverse force to the first push rod 1, pushing it to move away from the vent valve, thus achieving self-reset of the first push rod 1 and ensuring accuracy for the next strike.

[0034] like Figures 1 to 4 As shown, the reset mechanism includes a first spring 6 and a second spring 7. A pin 8 is mounted on the first push rod 1, sandwiched between the first spring 6 and the second spring 7. A groove is provided on the push rod cylinder 3 for the pin 8 to be embedded in, the length direction of which is parallel to the axis of the push rod cylinder 3. The pin 8 is fixedly mounted on the outer circumference of the first push rod 1, extending outwards towards the outside of the first push rod 1, and its length direction is parallel to a second direction. A second receiving groove is provided inside the push rod cylinder 3 to accommodate the first spring 6 and the second spring 7. The direction of the elastic force exerted by the first spring 6 on the pin 8 is opposite to the direction of the elastic force exerted by the second spring 7 on the pin 8. During each movement of the first push rod 1 by the drive mechanism, the pin 8 moves synchronously with the first push rod 1, compressing the first spring 6. The first spring 6 is used to apply an elastic force to the first push rod 1, causing it to move away from the vent valve, thereby achieving the self-reset of the first push rod 1. The second spring 7 is used to apply an elastic force to the second spring 7 during the reset process of the first push rod 1, which plays a role in shock absorption and buffering, reducing the impact and noise between parts, and helping to improve the service life of the tool.

[0035] like Figures 1 to 4As shown, two reset mechanisms are provided. Correspondingly, two pins 8 are provided on the first push rod 1, and the two pins 8 are coaxially arranged. The first push rod 1 is located between the two pins 8, and each pin 8 cooperates with one reset mechanism. In this embodiment, the first spring 6 and the second spring 7 of the reset mechanism are both cylindrical helical springs and are compression springs, and the first spring 6 and the second spring 7 are coaxially arranged. This type of reset mechanism has a simple structure, occupies little space, and is easy to arrange.

[0036] like Figures 1 to 3 As shown, the driving mechanism includes an electromagnet, which is positioned opposite to the first push rod 1. The electromagnet is a push-pull type and includes a coil housing 14, a coil support 15 fixedly mounted on the coil housing 14, a coil 17 mounted on the coil support 15, and a second push rod 2 movably mounted on the coil support 15. The second push rod 2 and the first push rod 1 are coaxially aligned and adjacent to each other. The coil housing 14 is fixedly located inside the outer casing. The coil support 15 is an open-end, hollow structure that is fitted onto the second push rod 2. A bushing 16 is also provided on the outer casing and fitted onto the second push rod 2. The coil housing 14 is located between the bushing 16 and the push rod cylinder 3. The bushing 16 is an annular structure that provides some support for the second push rod 2. When the coil is energized, a magnetic field is generated, allowing the second push rod 2 to move axially. After the second push rod 2 contacts the first push rod 1, it can apply a pushing force to the first push rod 1, thereby pushing the first push rod 1 to move linearly.

[0037] like Figure 3 As shown, a battery compartment and circuit board 5 are housed within the outer casing. A battery, acting as a power source, supplies electrical energy to the circuit board 5 and the electromagnet. The electromagnet is electrically connected to the circuit board 5. When the coil is energized, a magnetic field is generated. Under the control of the circuit board 5 control module, this magnetic field drives the second push rod 2, transmitting axial force to the first push rod 1 inside the push rod cylinder 3. This causes the gearbox breather valve, installed in the locking position of the push rod cylinder 3, to be driven into the gearbox mounting position. This reduces the need for manual positioning and tapping with a rubber mallet during valve installation, improving assembly efficiency.

[0038] like Figure 3 As shown, the outer casing is held by the operator during use. A switch button 13 is provided on the outer casing. The switch button 13 is rotatably connected to the outer casing. The rotation center line of the switch button 13 is parallel to the second direction when it rotates. The switch button 13 is used for the operator to operate with their fingers. When the switch button 13 is operated, causing it to rotate and press against the contact switch on the circuit board 5, the control circuit is activated. Then, the power supply can supply power to the coil to generate a magnetic field.

[0039] Figures 1 to 3As shown, the outer casing includes a first lower housing 11, a second lower housing 12, and an upper housing 10. The first lower housing 11 and the second lower housing 12 are arranged opposite to each other and are fixedly connected. The upper housing 10 is located above the first lower housing 11 and the second lower housing 12 and is fixedly connected to the first lower housing 11 and the second lower housing 12. The drive mechanism is fixedly arranged inside the upper housing 10. The push rod cylinder 3 and the locking mechanism are arranged inside the upper housing 10. An opening for the vent valve to pass through is provided on the top surface of the upper housing 10.

[0040] The present invention also provides a method for installing a transmission vent valve, using a transmission vent valve installation tool with the above-described structure, and including the following steps:

[0041] S1. Install the vent valve onto the gearbox vent valve installation tool;

[0042] S2. Install the vent valve on the gearbox using the gearbox vent valve installation tool.

[0043] In step S1 above, the vent valve to be installed is placed on the push rod cylinder 3. The locking mechanism cooperates with the push rod cylinder 3 to position the vent valve, and the locking mechanism locks the vent valve on the push rod cylinder 3. The vent valve will not move when no external force is applied to it, and the vent valve is in the locked position.

[0044] In step S2 above, the operator holds the installation tool. After the coil of the drive mechanism is energized, the drive mechanism controls the first push rod 1 to move. After the first push rod 1 contacts the vent valve and applies a pushing force to the vent valve, it can push the vent valve to move and continuously tap the vent valve multiple times, so that the vent valve can be installed in the gearbox mounting position.

[0045] In step S2 above, when the first push rod 1 pushes the vent valve to move, the locking element 4 moves after being pressured by the vent valve, squeezing the locking spring. The locking element 4 can move into the interior of the first receiving groove, so that the vent valve can continue to move towards the outside of the housing and finally be installed on the gearbox.

[0046] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
