Detailed Implementation The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1-5 As shown, this utility model is a locking structure for a shell-jointing machine, including a mounting frame 10. Locking components 11 are provided on both sides of the mounting frame 10, and the two sets of locking components 11 are symmetrical. The two sets of locking components 11 can approach each other to clamp the shell barrel. Each locking component 11 includes a fixing block 12, a clamping part 13, and a pushing part 14. Mounting posts 18 are fixedly installed on both sides of the outer wall of the fixing block 12. The mounting posts 18 are fixedly installed on the top of the mounting frame 10 by bolts. A dovetail engagement groove 19 is provided through the middle of the top of the fixing block 12, and a slider 15 is movably engaged in the corresponding dovetail engagement groove 19. By setting two sets of symmetrical locking components 11, the shell barrel can be simultaneously approached and clamped, avoiding deformation of the shell barrel or clamping deviation due to excessive force on one side. The dovetail engagement groove 19 and the slider 15 movably engage, enhancing the reliability of the movement.

[0018] like Figure 3-4As shown, the clamping part 13 includes a slider 15, a pad 23, and a clamping plate 16. A clamping groove 27, V-shaped, is provided on one side of the clamping plate 16 to accommodate barrels of different diameters. Multiple sets of first mounting holes 24 are provided through the top of the pad 23, which is located between the slider 15 and the clamping plate 16. Multiple sets of second mounting holes 26 are provided through the top of the clamping plate 16. The clamping plate 16 and the pad 23 are fixedly connected by bolts and nuts. A threaded mounting hole 22 is provided on one side of the top of the slider 15, and the slider 15 is fixed to the pad 23 and the clamping plate 16 by screws. Guide rods 25 are fixedly connected to both sides of the bottom of the pad 23. Guide grooves 20 are provided on both sides of the top of the fixing block 12, and the guide rods 25 are movably engaged in the corresponding guide grooves 20. An anti-detachment pressure plate 17 is fixedly installed at the middle position of the top of the fixing block 12, with the bottom end of the anti-detachment pressure plate 17 abutting against the tops of the two sets of guide grooves 20. By setting a clamping groove 27 on one side of the clamping plate 16, the clamping groove 27 is V-shaped, which improves the versatility of the device. Rubber pads can also be set on both sides of the V-shape of the clamping groove 27 to play a buffering role. Guide slide rods 25 are fixedly connected to both sides of the bottom end of the pad plate 23. Guide grooves 20 are set on both sides of the top end of the fixing block 12. The guide slide rods 25 are movably engaged in the corresponding guide grooves 20, which strictly restricts the movement direction of the clamping part 13 and ensures the stability of the clamping plate 16 during movement.

[0019] like Figure 5 As shown, the pushing unit 14 includes a nut fixing seat 28, a push plate 29, a lead screw 30, and a brake servo motor 31. The lead screw 30 movably passes through the nut fixing seat 28. The push plate 29 is fixedly installed on the top of the nut fixing seat 28. The push plate 29 is fixedly connected to one end of the slider 15 by screws. An adjustment cavity 21 is opened at the bottom of the fixing block 12. The adjustment cavity 21 communicates with the dovetail engagement groove 19. The nut fixing seat 28 is movably engaged in the adjustment cavity 21. The push plate 29 is located in the dovetail engagement groove 19. One side of the top of the nut fixing seat 28 is in contact with the bottom of the slider 15. The lead screw 30 is movably installed in the adjustment cavity 21. The lead screw 30 and the nut fixing seat 28 are connected by threads. A brake servo motor 31 is provided on the side of each of the two sets of fixing blocks 12 that is far apart from each other. The shaft of the brake servo motor 31 movably passes through the fixing block 12 through a coupling and is fixedly connected to one end of the lead screw 30. By setting the brake servo motor 31, the speed and direction can be precisely adjusted. Combined with the threaded transmission of the lead screw 30 and the nut fixing seat 28, the movement of the clamping part 13 can be precisely controlled. The brake servo motor 31 has a brake function. After clamping the barrel, it can immediately lock the lead screw 30 to prevent the lead screw 30 from reversing due to power failure of the brake servo motor 31 or equipment vibration, ensuring that the clamping part 13 always maintains a stable clamping state and provides a continuous and reliable clamping force for the shell joining process.

[0020] It should be noted that the brake servo motor 31 is prior art known to those skilled in the art. A control cabinet is also provided on one side of the mounting bracket 10. The control cabinet contains a PLC controller and a power supply module. The two sets of brake servo motors 31 are powered by dual-circuit independent power supply. The AC power is converted into DC power required for the operation of the brake servo motor 31 by the servo driver, which provides the driving force for the clamping action of the motor. An overload protector and a leakage circuit breaker are connected in series in the power supply circuit. Photoelectric encoders are installed on both sides of the slider 15 to collect the movement data of the slider 15 in real time and transmit the pulse signal to the PLC controller. The control cabinet is also provided with a start / stop operation panel for controlling the working status of the two sets of brake servo motors 31.

[0021] The implementation principle of the locking structure for a shell bonding machine of this utility model is as follows: First, the PLC controls two sets of brake servo motors 31 to rotate simultaneously in both directions. The shafts of the brake servo motors 31 drive the lead screw 30 to rotate through the coupling. The lead screw 30 engages with the nut fixing seat 28, causing the nut fixing seat 28 to move along the adjustment cavity 21. This, in turn, pushes the slider 15 to slide through the push plate 29. When the slider 15 moves the clamping part 13, the guide slide rod 25 at the bottom of the pad 23 slides along the guide groove 20, limiting the direction of movement of the clamping part 13 and ensuring that the clamping plate 16 is accurately aligned with the barrel. At the same time, the clamping groove 27 on one side of the clamping plate 16 is adapted to the diameter of the barrel. The rubber pad in the clamping groove 27 buffers the contact pressure. The photoelectric encoder provides real-time feedback on the displacement of the slider 15. The PLC adjusts the speed of the brake servo motor 31 according to the data. When the clamping plate 16 approaches the barrel, it switches to fine clamping until the pressure meets the requirements.

[0022] Then, when the contact pressure between the clamping plate 16 and the barrel reaches the set value, the PLC immediately stops the operation of the brake servo motor 31, cuts off the brake power supply circuit, and the brake servo motor 31 brakes and locks the lead screw 30 to prevent the lead screw 30 from reversing, so that the clamping part 13 maintains a stable clamping state and provides reliable clamping force for the shell assembly process.

[0023] Finally, after the shells are assembled, the operator issues a release command through the panel to reset the two clamping parts 13.

[0024] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
