[0032] like Figure 1 and 2 As shown, the utility model provides a tool for plugging and unplugging rocket take-off contacts, including: a bracket 3, an eccentric wheel mechanism and a telescopic rod 4. One end of the bracket 3 in the length direction is fixedly connected to the rocket take-off contact, and the other end is provided with an eccentric wheel mechanism. One end of the telescopic rod 4 is connected to the eccentric wheel mechanism, and the other end is used to resist the ejector pin of the rocket take-off contact. The eccentric wheel mechanism is used to drive the telescopic rod 4 to move along the length direction of the bracket 3, so that the telescopic rod 4 is away from or resists the ejector pin of the rocket take-off contact.

[0033] The tooling for plugging and unplugging rocket takeoff contacts provided in this embodiment utilizes an eccentric wheel mechanism to improve the efficiency of installation and plugging and unplugging of takeoff contacts, thereby improving the precision of the takeoff signal emission time and the accuracy of the test, and solving the problems of difficulty in plugging and unplugging takeoff contacts and large deviation in the takeoff contact triggering time.

[0034] According to an embodiment of the utility model, in addition to the bracket 3, the eccentric wheel mechanism and the telescopic rod 4, the tooling for plugging and unplugging the rocket take-off contact also includes a base 6. The bracket 3 is fixedly connected to the rocket take-off contact through the base 6. The base 6 is provided with a through hole, and the ejector pin of the rocket take-off contact passes through the through hole to abut against the telescopic rod 4.

[0035] In this embodiment, the base and the take-off contact can be fixed by bolts, and the bracket can be fixed to the frame base by screws. The tooling can increase the contact area between the base and the take-off contact on the rocket by increasing the area of ​​the base and the number of bolt holes and bolts accordingly, making the installation between the tooling and the take-off contact more convenient and quick.

[0036] According to an embodiment of the utility model, the eccentric wheel mechanism includes a handle 1 and a connecting rod 8. The handle 1 is rotatably connected to the bracket 3. Near the fixed end where the handle 1 is fixed to the bracket 3, one end of the connecting rod 8 is rotatably connected to one side of the handle 1, and the other end is rotatably connected to the telescopic rod 4. The handle 1 rotates around the bracket 3, driving the connecting rod 8 to drive the telescopic rod 4 along the length direction of the bracket 3 ( Figure 1 Move in the S direction).

[0037] In this embodiment, the handle can be fixed to the bracket by rivets and can rotate relative to the bracket. The handle and the connecting rod, the connecting rod and the telescopic rod can be connected by rivets and can rotate relative to each other to form a mechanism with an eccentric wheel principle. The telescopic rod can be extended and retracted up and down by rotating the handle. Figure 1 The S direction in the figure is consistent with the compression and ejection direction of the take-off contact ejector pin.

[0038] According to an embodiment of the utility model, the connecting rod 8 is in an arc shape, and the fixed end of the handle 1 is in an arc shape adapted to the connecting rod 8. In the initial state, the side of the handle 1 connected to the connecting rod 8 faces the telescopic rod 4, and the telescopic rod 4 abuts against the ejector pin of the rocket take-off contact. When the handle 1 is turned, the side of the handle 1 connected to the connecting rod 8 rotates in a direction away from the telescopic rod 4, and the handle 1 drives the connecting rod 8 to move along the length direction of the bracket 3, so that the connecting rod 8 is loosened and away from the ejector pin of the rocket take-off contact.

[0039] For example, the telescopic rod can be set to the initial state against the ejector pin of the rocket take-off contact. Figure 1 and Figure 2 For example, Figure 2 It is the initial state, at which the eccentric wheel mechanism is in a locked state and the ejector pin of the rocket take-off contact is compressed. Figure 1 In order to complete the state of pulling up the rocket take-off contact, the balance state of the eccentric wheel mechanism is destroyed at this time, and the ejector pin of the rocket take-off contact pops out. In the initial state, the side of the handle connected to the connecting rod faces the telescopic rod, and the telescopic rod presses against the ejector pin of the rocket take-off contact. Turn the handle of the eccentric wheel mechanism clockwise, and under the elastic force of the eccentric wheel mechanism and the take-off contact, the eccentric wheel mechanism rotates rapidly, the telescopic rod gives way, and the ejector pin of the take-off contact pops out rapidly, completing the operation of pulling up the take-off contact. Turn the handle of the eccentric wheel mechanism counterclockwise, and the telescopic rod pushes the ejector pin of the take-off contact to compress the elastic element of the take-off contact. When the handle reaches the initial position (i.e., the locked state of the eccentric wheel mechanism), the ejector pin and the telescopic rod of the take-off contact provide locking force to the eccentric wheel mechanism under the elastic force of the take-off contact, completing the operation of pressing the take-off contact.

[0040] In this embodiment, the rotation angle of the handle can be controlled by controlling the arc angle of the connecting rod and the position of the connecting rod relative to the handle.

[0041] According to one embodiment of the utility model, a rotating screw 5 is provided at one end of the telescopic rod 4 away from the eccentric wheel, and the rotating screw 5 is threadedly connected to the telescopic rod 4. The rotating screw 5 can be screwed in or out relative to the telescopic rod 4 to resist the ejector pin of the rocket take-off contact.

[0042] The existing tooling needs to rely on experience to control the installation process of the screws. In the initial state, the tooling of this embodiment can achieve the required adjustment amount by rotating the rotating screw according to the required compression amount, thereby improving the control accuracy of the take-off contact compression amount and solving the problem of poor control accuracy of the take-off contact compression amount.

[0043] According to an embodiment of the utility model, the rotating screw 5 is sleeved with a nut 10 , and the nut 10 is used to fasten the rotating screw 5 and the telescopic rod 4 .

[0044] In this embodiment, when the eccentric wheel mechanism is locked, the accuracy of its linear progress can be controlled by rotating the rotating screw to fine-tune the compression amount of the take-off contact ejector pin. For example, the compression amount of the take-off contact ejector pin can be measured by a ruler to determine whether the compression amount meets the requirements.

[0045] According to an embodiment of the utility model, the bracket 3 is fixedly provided with a sleeve 11. The telescopic rod 4 is sleeved inside the sleeve 11 and can slide relative to the sleeve 11. The sleeve 11 is used to limit the telescopic rod 4 in the radial direction.

[0046] like Figure 3 and 4 As shown, according to an embodiment of the utility model, a safety pin 2 is provided on the end surface of the bracket 3 close to the handle 1 , and the safety pin 2 is rotatable relative to the end surface of the bracket 3 to limit the rotation of the handle 1 relative to the bracket 3 .

[0047] According to an embodiment of the utility model, a spring screw 9 is provided on the end surface of the bracket 3 close to the handle 1 , and the spring screw 9 is used to resist the safety pin 2 so that the safety pin 2 blocks the handle 1 in the rotation direction of the handle 1 .

[0048] like Figure 3 As shown, when the eccentric mechanism is in a locked state, the safety pin rotates to the side close to the handle, blocking the handle in the direction of rotation, further strengthening the locking of the eccentric mechanism. The tooling of the embodiment of the present application can adjust the progress of the rotating screw relative to the telescopic rod to make the compression amount of the take-off contact ejector meet the requirements. The safety pin is rotated 180° clockwise around the end face of the bracket close to the handle to unlock the safety pin until the safety pin makes room for the handle to rotate (such as Figure 4As shown). Turn the handle of the eccentric mechanism counterclockwise 180° to move the connecting rod and destroy the balance state of the eccentric mechanism. Under the joint action of the elastic force of the eccentric mechanism and the ejector pin of the take-off contact, the eccentric mechanism rotates rapidly, the rotating screw makes way for the ejector pin, and the ejector pin of the take-off contact pops out rapidly, completing the operation of plugging and unplugging the take-off contact. When the take-off contact state needs to be restored, turn the handle of the eccentric mechanism counterclockwise to move the connecting rod, and the telescopic rod pushes the rotating screw toward the ejector pin until the rotating screw pushes the ejector pin of the take-off contact to be compressed. When the eccentric mechanism reaches the locked position, the elastic force (such as spring force) of the telescopic rod and the ejector pin of the take-off contact provides the locking force of the eccentric mechanism, completing the clamping operation of the take-off contact. Finally, turn the safety pin counterclockwise 180° to lock the safety pin.

[0049] For example, spring screws are arranged at both ends of the end surface of the bracket close to the handle, and the safety pin can be fixed when the safety pin is rotated to block the handle or to make room for the handle to rotate. The safety pin can be L-shaped and can be made of iron material.

[0050] This embodiment takes the handle rotating 180° as an example in order to conveniently and intuitively describe the plugging and unplugging process of the take-off contact ejector pin, and is not intended to limit the protection scope of the present utility model.

[0051] According to an embodiment of the utility model, in addition to the bracket 3, the eccentric wheel mechanism and the telescopic rod 4, the tooling for plugging and unplugging the rocket take-off contacts also includes a rocket take-off contact fixedly connected to the rocket body.

[0052] In this embodiment, an elastic element (such as a spring) can be arranged inside the ejector pin of the take-off contact, so that the ejector pin has its own spring force. When the ejector pin is pressed down, it is set as a normally open contact, and when the ejector pin bounces up, the contact is closed and a take-off signal is issued at the same time.

[0053] like Figure 5 As shown, according to an embodiment of the present utility model, the bracket 3 is provided with a protective cover 7, and the protective cover 7 is used to surround the eccentric wheel mechanism from the outside to prevent external force from touching the eccentric wheel mechanism.

[0054] The existing take-off contact plugging and unplugging tooling is made of hard steel. According to an embodiment of the utility model, the tooling can be made of carbon aluminum, thereby reducing the weight of the tooling.

[0055] The above-mentioned embodiments of the present invention can be combined with each other and have corresponding technical effects.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
