Example 1

Referring to fig. 1 and 2, the present embodiment provides a transmission vent plug assembling tool, including a main body 10, an air storage component 20, a fixture 30 and a fixture 40, where an air inlet pipeline 11 is disposed in the main body 10, one end of the air inlet pipeline 11 is used for being connected to an external air source for increasing compressed air, and the other end of the air inlet pipeline is communicated with the air storage component 20, a switch device for opening and closing the air inlet pipeline 11 is disposed on the air inlet pipeline 11, one end of the fixture 30 is slidably connected to the main body 10, and the opposite end of the fixture is detachably connected to the fixture 40, the fixture 40 is used for clamping the vent plug 50, a first air flow channel 31 having an open end and a closed end is disposed in the fixture 30, and an open end of the first air flow channel 31 is communicated with the air storage component 20.

Wherein the main body 10 is used for holding and mounting other parts by an operator. The gas storage member 20 is used to store a certain amount of compressed gas. Compressed air supplied from an external air source enters the air storage element 20 of the assembly tool through the air inlet pipeline 11, and the compressed air has a certain pressure, so that the compressed air can enter the first air flow channel 31 from the open end of the first air flow channel 31 under the action of the pressure. Since the first air flow passage 31 in the clamp 30 is closed at one end, the compressed air can push the clamp 30 to slide away from the main body 10 under pressure. Because the end of the clamp 30 far away from the main body 10 is connected with the tool 40, and the tool 40 is provided with the vent plug 50, the clamp 30 can rapidly drive the vent plug 50 to move under the action of compressed air. The transmission vent plug 50 assembling tool of the embodiment can align the vent plug 50 clamped on the tool 40 with the vent plug 50 hole on the transmission box body, and then press the switch device to open the air inlet pipeline 11, so that the compressed air enters the air storage element 20. The compressed gas in the gas storage component 20 pushes the clamp 30 to move forward rapidly when entering the first gas flow channel 31, so as to drive the vent plug 50 to enter the hole of the vent plug 50 rapidly, and therefore, the assembly efficiency is high. As a preferred embodiment, the gas storage member 20 in this embodiment is an air bag.

Although the assembly tool of this embodiment may utilize compressed gas to quickly push the vent plug 50 into the vent plug 50 hole, the fixture 30 may need to be repositioned after removal for reuse, which may reduce efficiency if manual repositioning is used. For this, the vent plug 50 further includes a first elastic restoring member 60, one end of the first elastic restoring member 60 is fixedly connected to the main body 10, and the other opposite end is connected to the clamp 30, and when the clamp 30 relatively moves in a direction away from the main body 10 under the action of the airflow, the first elastic restoring member 60 generates an elastic force that moves the clamp 30 in a direction close to the main body 10.

As described with reference to fig. 2 and 3, when the clamp 30 is pushed forward by the compressed gas, the movement of the clamp 30 elastically deforms the first elastic restoring member 60. The elastic reset piece generates elastic deformation and then generates a force for restoring the deformation, and the force for restoring the deformation is the elastic force of the reset piece in the direction. The clamp 30 is moved in the opposite direction by the elastic force to return to the position before the compressed air is introduced, so that the rapid automatic reset is realized. In this embodiment, the first elastic restoring member 60 may be a spring, wherein one end of the spring is fixedly connected to the main body 10, and the other end of the spring is fixedly connected to the clamp 30. When no compressed gas is introduced, the clamp 30 is in an initial position, in which the spring is in its natural length, neither compressed nor extended. When the compressed gas is introduced, the clamp 30 is pushed by the compressed gas to move forward. The spring is stretched by the clamp 30, and the spring is stretched to generate an elastic force for pulling the clamp 30 back.

As shown in fig. 2, in this embodiment, in order to conveniently control the on/off of the air intake pipeline 11, the switch device is a slider 12 that is movable relative to the main body 10, a second air flow channel 121 that penetrates through the slider 12 is provided in the slider 12, and when the switch device is closed by the slider 12, the air intake pipeline 11 is opened by the switch device when the slider moves to a position where the second air flow channel 121 is communicated with the air intake pipeline 11. The present embodiment provides a slider 12 capable of sliding with respect to the main body 10, and the slider 12 is provided with an air flow passage, i.e., a second air flow passage 121. The slide block 12 can drive the second air flow channel 121 to move along with the slide block in the moving process, and since the position of the air inlet pipeline 11 is fixed relative to the main body 10, when the slide block 12 drives the second air flow channel 121 to move relative to the main body 10, the position relationship between the second air flow channel 121 and the air inlet pipeline 11 is also changed. When the second air flow passage 121 is in a position to communicate the intake pipes 11 on both sides thereof, the intake pipes 11 are opened. When the second air flow path 121 is in a position offset from the intake pipes 11 on both sides, the intake pipes 11 are closed. Therefore, the present embodiment can conveniently control the on-off of the air intake pipeline 11 by using the movement of the sliding block 12 relative to the main body 10.

A second elastic restoring member 70 is provided in the main body 10 at a position corresponding to the slider 12, and the second elastic restoring member 70 generates a force for driving the slider 12 to move in a direction in which the second air flow path 121 and the intake pipe are displaced when the slider 12 moves in a direction in which the second air flow path 121 and the intake pipe can be communicated with each other.

As shown in the drawings, the second elastic restoring member 70 may be a spring, one end of which abuts against or is connected to one inner wall of the main body 10, and the other end of which abuts against or is connected to an end of the slider 12, and when an operator moves closer to the inner wall of the main body 10, the spring is compressed to generate an elastic restoring force. When the operator releases the slider 12, the slider 12 is moved in the opposite direction by the elastic restoring force of the spring. After adopting the above structure, when the operator presses the slider 12, the slider 12 moves to open the air intake pipeline 11, and the compressed air enters the air storage element 20. When the operator releases the slider 12, the slider 12 moves to close the air intake line 11. At this time, the reservoir member is in a closed state, and the compressed air in the air reservoir member 20 maintains a certain pressure, so that the clamp 30 can be rapidly pushed to move.

In this embodiment, the air storage element 20 is provided with a pressure relief switch 21, and when the pressure relief switch 21 is turned on, a portion of the air storage element 20 for storing compressed air is communicated with the outside. When the transmission vent plug 50 assembling tool of the present embodiment has mounted one vent plug 50, the pressure relief switch 21 may be turned on, and then the compressed air may be discharged to the outside of the air container 20 through the pressure relief switch 21, so that the air pressure inside the reservoir member is reduced, and the clamp 30 returns to the initial position by the first elastic reset key. In this embodiment, the pressure relief switch 21 may be a screw plug, and for this purpose, a screw hole may be provided in the main body 10 and/or the gas storage element 20. When the screw plug is tightly coupled with the screw hole, the gas storage member 20 is closed. When the operator twists the plug screw to the threaded hole to connect the reservoir member to the outside, the pressure relief switch 21 is opened.

As shown in fig. 1, in the present embodiment, as one of preferable embodiments, the main body 10 includes a grip handle 13, and the switch device is disposed on the grip handle 13. Thus, when the transmission vent plug 50 assembling tool of the present embodiment is used to assemble the vent plug 50, an operator can hold the holding handle 13 by hand and then conveniently press the switch device to control the movement of the clamp 30.

As shown in fig. 2, a check valve 14 is disposed on the intake pipe 11 between the switching device and the gas storage element 20, and the check valve 14 opens in one direction toward the gas storage element 20. The present embodiment prevents the compressed air in the air storage element 20 from leaking out and affecting the pressure in the reservoir element by allowing the compressed air to flow only from the air intake line 11 into the air storage element 20, but not from the air storage element 20 into the air intake line 11 through the check valve 14 provided in the air intake line 11.

As shown in fig. 4, in this embodiment, a clamping portion is disposed at an end of the fixture 30 far away from the main body 10, the clamping portion includes a plurality of clamping pieces 32 disposed along a circumferential direction of the fixture 30, a gap is left between the clamping pieces 32, one end of each clamping piece 32 is a free end, the fixture 30 further includes a locking nut 34, and the locking nut 34 can move along an axial direction of the fixture 30 to a position where an inner wall thereof presses the clamping pieces 32 to approach towards an axis of the fixture 30.

The operator inserts the tool 40 with the vent plug 50 into the space defined by the clamping pieces 32 and then moves the lock nut 34 toward the tool 40, wherein the lock nut 34 forces the clamping pieces 32 toward the center during the movement to clamp the tool 40.

As shown in fig. 2, in this embodiment, as a preferred embodiment, the air storage component 20 and the first air flow channel 31 are communicated through an air flow pipe that can be extended and retracted along the axial direction of the fixture 30. The air flow pipe which can be extended and contracted in the axial direction of the jig 30 may employ a bellows 80. Because the clamp 30 can move axially, the clamp 30 is communicated with the air storage element 20 by using the corrugated pipe 80, and the corrugated pipe 80 can stretch and contract along with the axial movement of the clamp 30, so that the clamp 30 can move freely and the sealed delivery of the compressed air is realized.

As shown in fig. 3, as one preferred embodiment, in the present embodiment, a limiting portion 33 is provided on the clamp 30, a limiting cavity 15 which is matched with the limiting portion 33 is provided in the main body 10, the limiting portion 33 slides in the limiting cavity 15, and limiting walls for limiting the range of sliding of the limiting portion 33 in the limiting cavity 15 in the axial direction are provided at both ends of the limiting cavity 15 in the radial direction.

In order to accurately assemble the transmission vent plug 50 to the predetermined position of the vent plug 50 hole during assembly, the vent plug 50 assembly tool of the present embodiment is further provided with a limiting structure consisting of the limiting portion 33 on the jig 30 and the limiting cavity 15 on the main body 10. When the jig 30 is moved to a predetermined position by the compressed gas, the stopper 33 is just stopped by the stopper wall, so that the assembling position of the vent plug 50 can be precisely controlled by setting the position of the stopper wall.

As described above, only for the specific implementation manner of the present invention, those skilled in the art can clearly understand that, for convenience and simplicity of description, the specific working process of the system, the module and the unit described above can refer to the corresponding process in the foregoing method embodiments, and will not be described again here.
