Description

Technical Field

[0001] The utility model belongs to the technical field of zero position detection, in particular to a zero position detection device for automatic tightening of a gun. Background Art

[0002] In the prior art, the mechanical plug shaft and the gun barrel of the relevant artillery zero position detection device mostly use traditional elastic tightening, hand wheel rotation locking and push-pull locking methods in combination with an optical zero position detection device.

[0003] The traditional mechanical plug-in shaft locking process will generate a radial force on the mechanical plug-in shaft due to human operation, and the magnitude of the radial force varies. In addition, the zero-position deviation of the entire detection result will be different as the value of the radial force varies.

[0004] The traditional mechanical shaft clamping process results in zero-position deviations due to the force applied by different operators. Furthermore, the resulting zero-position deviations vary with the force applied. Therefore, an automatic zero-position detection device for artillery clamping is urgently needed to reduce the impact of zero-position deviations caused by manual operation and improve the device's operability. Summary of the Invention

[0005] To this end, the present invention provides a device for detecting the zero position of an automatic tightening gun, which can solve the technical problem of the zero position deviation caused by the manual operation process mentioned in the background technology.

[0007] One end of the reference plug shaft is provided with an expansion sleeve, and the other end of the reference plug shaft is a tapered surface;

[0008] One end of the transfer rod is mounted on the other end of the reference plug shaft, one end of the mounting box is mounted on the other end of the transfer rod, and the other end of the mounting box is mounted with a zero position detection component;

[0009] The motor and power supply are installed in the installation box, the rotating shaft of the motor is in transmission connection with one end of the transfer rod, the other end of the transfer rod is connected to the expansion body, and the transfer rod is inserted into the quasi-insertion shaft and the transfer rod;

[0010] The control switch is used to control the forward and reverse rotation of the motor, and the motor controls the connecting rod to move forward and backward by forward and reverse rotation;

[0011] The expansion body is placed in the expansion sleeve, and driven by the connecting rod, the expansion body expands the expansion sleeve.

[0012] Furthermore, the expansion sleeve and the positioning cone are integrally formed with the reference plug shaft.

[0013] Furthermore, the expansion sleeve is a split cone-shaped structure, and the size of the inner hole of the expansion sleeve is adapted to the size of the expansion body.

[0014] Furthermore, the zero position detection component includes an electronic collimator and a display and control component communicatively connected to the electronic collimator.

[0015] Furthermore, the zero position detection component includes a human eye collimator.

[0016] Furthermore, the rotating shaft of the motor is provided with an external thread, one end of the connecting rod is provided with an internal thread adapted to the external thread, and the connecting rod is provided with a guide ring, which can slide axially in the transfer rod.

[0017] The beneficial effects of this utility model include: The motor drives the reference plug shaft to tighten against the gun barrel via an expansion mechanism, transferring the gun barrel axis to the axis of the reference plug shaft. An optical zero position detection component connected to the reference plug shaft then detects the gun zero position deviation. During installation and testing, the utility model reduces radial force deviation caused by manual manipulation of the reference plug shaft during tightening. Furthermore, the tightening force can be adjusted during the tightening process, reducing zero position deviations caused by inconsistent manual tightening force. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts should fall within the scope of protection of the present invention.

[0021] In an embodiment of the present invention, Figure 1 This is a structural diagram provided according to the specific structure of a gun automatic tightening zero position detection device of the utility model, as shown in FIG. Figure 1 As shown, the utility model includes:

[0022] Expansion body 1, reference plug shaft 2, connecting rod 3, transfer rod 4, installation box 6, motor 7, power supply 8, control switch 9 and zero position detection component;

[0023] One end of the reference plug shaft 2 is provided with a clamping sleeve 21, and the other end of the reference plug shaft 2 is provided with a positioning cone 22. Specifically, the clamping sleeve 21 and the positioning cone 22 are integrally formed with the reference plug shaft 2. The reference plug shaft of this detection device utilizes a clamping sleeve structure with a positioning cone on one end and a 360-degree expansion sleeve on the other end, ensuring a full fit with the barrel of the gun under test. Using the principle of two points confirming a straight line, the barrel axis of the gun under test is transferred to the axis of the mechanical plug shaft, and the center value of the barrel axis scale of the gun under test is then read by the zero position detection component.

[0024] One end of the transfer rod 4 is mounted on the other end of the reference plug shaft 2, one end of the mounting box 6 is mounted on the other end of the transfer rod 4, and the other end of the mounting box 6 is mounted with a zero position detection component, wherein the mounting box 6 is connected to the transfer rod 4 by bolts.

[0025] The motor 7 and the power supply 8 are installed in the installation box 6. The rotating shaft of the motor 7 is in transmission connection with one end of the transfer rod 4. The other end of the transfer rod 4 is connected to the expansion body 1. The connecting rod 3 is inserted into the quasi-insertion shaft 2 and the transfer rod 4.

[0026] The control switch 9 is used to control the forward and reverse rotation of the motor 7, and the motor 7 controls the forward and reverse rotation of the connecting rod 3. The motor is a DC motor, and the motor torque can be set according to product requirements to ensure that the tensioning force of different operators is consistent when using the device.

[0027] The expansion element 1 is placed within the expansion sleeve 21. Driven by the connecting rod 3, the expansion element 1 expands the expansion sleeve 21. Specifically, the motor drives the connecting rod backward, causing the expansion element to move toward the motor, thereby expanding the expansion sleeve 21 and achieving expansion. Conversely, the expansion sleeve retracts. The expansion sleeve 21 has a split-flank conical structure, and the expansion element 1 is conical or spherical. The inner hole size of the expansion sleeve 21 is adapted to the size of the expansion element 1. This ensures that the expansion sleeve 21 maintains close contact with the inner wall of the gun barrel during movement.

[0028] Among them, the rotating shaft of the motor 7 is provided with an external thread, one end of the connecting rod 3 is provided with an internal thread adapted to the external thread, and the connecting rod 3 is provided with a guide ring 5, which can slide axially in the adapter rod 4. The guide ring can prevent the connecting rod 3 from rotating with the motor shaft, so that the connecting rod can only move in a straight line.

[0029] In embodiment 1 of the present invention, Figure 1 As shown, the zero-position detection component includes an electronic collimator 10 and a display and control assembly 11 in communication with the electronic collimator 10. It is connected to the mounting box 6 via a standard interface adapter, aligning the center of the electronic reticle of the electronic collimator 10 with the axis of the reference plug-in shaft. The display and control assembly 11 serves as the human-machine interface for the electronic collimator 10. Both the electronic collimator 10 and the display and control assembly 11 are conventional techniques known to those skilled in the art and will not be described in detail here.

[0030] In embodiment 2 of the present invention, Figure 2 As shown, the zero-position detection component includes a human eye collimator 12. Connected to the mounting box 6 via a standard interface adapter, the center of the human eye collimator's reticle is aligned with the axis of the reference plug-in shaft. In extreme cases where the electronic collimator fails, such as due to battery failure or strong electromagnetic interference, it can be downgraded to a conventional human eye collimator, thus ensuring operational requirements.

[0031] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
