Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch device technology, and specifically discloses a compact limit switch mounting base structure with commutation function. Background Technology
[0002] Currently, some ceremonial cannons require automated firing capabilities, necessitating automatic detection of the breechblock's status to ensure it is in the open position during ammunition loading and in the closed position after the final firing. With unmanned operation, the internal mechanisms are compactly arranged, leaving limited installation space for the fire control section in the width direction. Existing products have the breechblock limit switches mounted perpendicular to the gun axis, which interferes with the internal mechanisms and cannot meet the space constraints. Figure 1 As shown.
[0003] To address the above requirements, a compact limit switch mounting base structure with reversing function needs to be designed. The limit switch is fixed on the mounting base, allowing the installation method of the limit switch to be reversed by 90°. This not only meets the installation requirements within a limited space but also enables reliable output of the switch latch position signal, meeting the requirement of automatic detection of the switch latch status during automatic firing. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a compact limit switch mounting base structure with reversing function, solving the problem of not being able to install limit switches in limited space. It enables the output of open and close latch position signals, and the position signals are accurate and reliable. It can automatically detect the state of the latch body, providing judgment conditions for the automated completion of the firing function.
[0005] This utility model is achieved through the following technical solution:
[0006] A compact limit switch mounting base structure with reversing function includes a mounting base body 1, a reversing device 2, a pin 3, a torsion spring 4, a cotter pin 5, and a fixing device 6.
[0007] The mounting base body 1 is a plate with several fixing holes on its surface. A pair of symmetrical annular columns are provided on one side of the plate as pin holes, and a torsion spring mounting groove is provided inside the pin holes. The mounting base body 1 provides a mounting base for limit switches and reversing devices.
[0008] The reversing device 2 includes plane A and plane B. One side of plane A is provided with a bent end. The non-bent end side of plane A and plane B are connected by a ring structure. The panel directions of plane A and plane B are perpendicular to each other. The reversing device 2 is provided with a torsion spring 4 mounting groove and mounting hole. The reversing device 2 causes the direction of the contact rod pressing the limit switch to change by 90°.
[0009] The annular structure of the reversing device 2 is located between the pin holes of the mounting body 1. The pin 3 passes through the pin holes and the annular structure, connecting the mounting body 1 and the reversing device 2. The torsion spring 4 is inserted into the corresponding hole in the mounting groove of the reversing device 2.
[0010] The cotter pin 5 is located on the side of the pin 3 and is used to position the pin;
[0011] The fixing device 6 is fixedly installed onto the protective plate by the mounting base body 1;
[0012] The torsion spring 4 ensures that when the reversing device 2 is not subjected to external force, the plane B of the reversing device 2 does not contact the corresponding limit switch; the plane A of the reversing device 2 is located on the travel path of the breech contact rod that cooperates with the mounting base.
[0013] Preferably, the fixing device 6 is a screw.
[0014] Preferably, the fixing device 6 is used in conjunction with the breech guard.
[0015] Preferably, the mounting plate on the plate surface of the mounting base body 1 is further provided, and the mounting plate is used to fix the limit switch.
[0016] Preferably, the mounting base body 1 has four mounting holes on its plate surface, which are arranged in a rectangular pattern.
[0017] Preferably, the side of the bent end of plane A of the reversing device 2 is close to the breech contact rod.
[0018] Preferably, the annular column on the mounting base body 1 where the pin 3 is mounted has a protrusion for limiting the reversing device 2, ensuring the required distance between the plane A of the reversing device 2 and the breech.
[0019] The beneficial effects of this utility model are reflected in:
[0020] Compared with the prior art, the present invention proposes a compact limit switch mounting base structure with reversing function, which can accurately and reliably output the breech opening and closing signals within a limited installation space, realize the monitoring of the breech position status, and provide support for automated gun firing.

It should be understood that the embodiments are only used to illustrate the technical effects of this utility model and are not intended to limit the scope of protection of this utility model.
[0033] Example 1
[0034] A compact limit switch mounting base structure with reversing function includes a mounting base body 1, a reversing device 2, a pin 3, a torsion spring 4, a cotter pin 5, and a fixing device 6.
[0035] The mounting base body 1 is a plate with several fixing holes on its surface. A pair of symmetrical pin holes are provided on one side of the plate, and a torsion spring mounting groove is provided inside the pin holes. The mounting base body 1 provides a mounting base for the limit switch and the reversing device.
[0036] The reversing device 2 includes plane A and plane B. One side of plane A is provided with a bent end. The non-bent end of plane A and plane B are connected by a ring structure. The panel directions of plane A and plane B are perpendicular to each other. The reversing device 2 is provided with a torsion spring 4 mounting groove and mounting hole. The protruding part contacts the protrusion of the mounting base body 1 for limiting. The reversing device 2 causes the direction of the contact rod pressing the limit switch to change by 90°.
[0037] The annular structure of the reversing device 2 is located between the pin holes of the mounting body 1. The pin 3 passes through the pin holes and the annular structure, connecting the mounting body 1 and the reversing device 2. The torsion spring 4 is inserted into the corresponding hole in the mounting groove of the reversing device 2. The mounting plate of the mounting body 1 is also provided with a mounting plate, which is used to fix the limit switch.
[0038] The cotter pin 5 is located on the side of the pin 3 and is used to position the pin;
[0039] The fixing device 6 is fixedly installed onto the protective plate by the mounting base body 1;
[0040] The torsion spring 4 ensures that when the reversing device 2 is not subjected to external force, the plane B of the reversing device 2 does not contact the corresponding limit switch; the plane A of the reversing device 2 is located on the travel path of the breech contact rod that mates with the mounting base. The fixing device 6 is a screw. The fixing device 6 mates with the breech guard plate. The mounting base body 1 has four mounting holes arranged in a rectangular pattern on its plate surface.
[0041] Preferably, the side of the bent end of plane A of the reversing device 2 is close to the breech contact rod.
[0042] Mounting base body 1, see Figure 3 , Figure 4 , Figure 6 ;
[0043] The reversing device 2 is used to change the direction of the contact rod pressing the limit switch by 90°, ensuring reliable output of the open / close latch position signal within a limited space and guaranteeing the automatic firing function of the gun. The reversing device 2 is equipped with a torsion spring 4 mounting groove and mounting hole; the protruding part contacts the protrusion of the mounting base body 1 for limiting movement. (See...) Figure 3 , Figure 4 , Figure 7 ;
[0044] Pin 3 connects mounting base body 1, reversing device 2, and torsion spring 4, see Figure 3 , Figure 4 , Figure 8 ;
[0045] Torsion spring 4 is used for resetting the commutator 2, see Figure 3 , Figure 4 , Figure 9 ;
[0046] Cotter pin 5 is used for positioning pin 3, see... Figure 3 , Figure 4 , Figure 10 ;
[0047] Fixing device 6 is a screw used to mount the mounting base to the protective plate, see Figure 3 , Figure 4 , Figure 11 .
[0048] The principle of this invention is as follows: when the breechblock is in the open or closed position, the contact rod installed inside the breech extends and presses the reversing device, which in turn presses the limit switch, thus activating the limit switch. Figure 5As shown, the output breech-opening and breech-closing signals provide the judgment conditions for automated artillery firing.
[0049] The specific working process of this mounting bracket structure is as follows:
[0050] When the breechblock is in the open or closed position, the contact rod installed inside the breech extends and presses the A side of the reversing device, causing the reversing device 2 to rotate around the pin. At the same time, the B side of the reversing device 2 presses the limit switch fixed on the mounting body 1, causing the contact rod to change the pressing direction by 90° and connect the limit switch, thus realizing the reliable output of the open and closed breech signals.
[0051] When the breechblock is not in the correct position, the contact rod installed inside the breech retracts, and the reversing device rotates in the reverse direction under the action of the torsion spring 4 until the limiting plane of the reversing device 2 contacts the limiting block on the mounting body 1, thereby resetting the reversing device. At the same time, the B surface of the reversing device 2 disengages from the limit switch contact rod, the limit switch is opened, and the open and close breech signals disappear.
[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle, and these improvements and modifications should also be considered within the scope of protection of the present invention.
