Description

[0002] In modern industrial production, shaped charge pipe fittings are widely used in many fields such as oil extraction, blasting engineering, and military equipment. For example, in oil extraction, shaped charge pipe fittings are used in perforation operations, and the accuracy of their positioning directly affects the oil well's production efficiency; in blasting engineering, the precise positioning of shaped charge pipe fittings is crucial to the blasting effect and construction safety.

[0003] Currently, some energy-concentrating pipe fitting positioning devices on the market use relatively simple clamping methods, usually relying on a single structure to fix the pipe fitting and using only clamps for locking. When facing energy-concentrating pipe fittings of different specifications, shapes, and materials, it is difficult to provide comprehensive and stable clamping force. When positioning energy-concentrating pipe fittings, existing positioning devices require operators to manually adjust the position of the pipe fitting to make its central axis coincide with the expected positioning axis of the processing equipment. In addition, for key components such as the lead screw driving the clamping parts, existing devices lack effective locking measures. The lead screw is prone to shaking and rotation during operation due to vibration or external force, which can lead to loosening of clamping components such as the pressing ring, causing the positioning of the energy-concentrating pipe fitting to fail. Therefore, this utility model provides a positioning device for energy-concentrating pipe fittings. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a limiting and positioning device for energy-concentrating pipe fittings, including a mounting base 1, on which a mounting mechanism for limiting and positioning energy-concentrating pipe fittings is provided, the mounting mechanism including:

[0024] The clamping assembly includes a mounting bracket 2 provided on the upper end face of the mounting base 1. A V-groove 201 is provided on the upper end of the mounting bracket 2. A top plate 202 is fixed on the top end of the mounting bracket 2. A pressing ring 204 connected by a threaded assembly is provided inside the top plate 202. A support block 403 is fixed on the upper inner wall of the V-groove 201. A lower pressure plate 404 is rotatably connected by a rotating shaft inside the support block 403.

[0025] The locking assembly includes a slide rail bracket 3 fixed to the upper end of the top plate 202. The slide rail bracket 3 has a clamping plate 301 connected by an opening and closing assembly inside. The inner wall of the clamping plate 301 has a locking groove 302.

[0026] In a preferred embodiment, the inner wall of the V-groove 201 is provided with rubber pads for anti-slip. When the energy-concentrating pipe is placed in the V-groove 201 opened at the upper end of the mounting bracket 2, the rubber pads on the inner wall of the V-groove 201 increase the friction between the pipe and the V-groove 201, playing an anti-slip role and initially stabilizing the radial position of the pipe. At the same time, the structural features of the V-groove 201 can automatically center the pipe, so that the central axis of the pipe basically coincides with the expected positioning axis of the device.

[0027] In a preferred embodiment, the threaded assembly includes a lead screw 203 vertically threaded inside the top plate 202, a pressing ring 204 located at the lower end of the lead screw 203 and rotatably connected to the lead screw 203, rubber plugs 205 evenly distributed on the contact surface between the pressing ring 204 and the energy-concentrating pipe fitting, and guide grooves 206 on both sides of the mounting bracket 2. A guide rod 207 is slidably connected inside the guide groove 206, and one end of the guide rod 207 is fixedly connected to the pressing ring 204 for pressing the V-groove 201 inside. The placed energy-concentrating pipe fitting is pressed down and clamped. The screw 203 is rotated. Since the screw 203 is vertically threaded to the top plate 202, the screw 203 will move downward in the vertical direction when it rotates. The pressing ring 204 at the lower end of the screw 203 moves downward accordingly, pressing down on the energy-concentrating pipe fitting in the V-groove 201. Then, the rubber plugs 205 evenly distributed on the contact surface between the pressing ring 204 and the energy-concentrating pipe fitting further increase the friction on the pipe fitting, preventing the pipe fitting from sliding during the pressure process, and also protecting the surface of the pipe fitting from being scratched.

[0028] The guide rod 207 slides in the guide groove 206, providing guidance for the downward movement of the pressing ring 204, ensuring that the pressing ring 204 presses down vertically, so that the pipe is subjected to uniform force and avoids pipe deformation or inaccurate positioning due to inclined force.

[0029] In a preferred embodiment, the opening and closing assembly includes a bidirectional screw 303 rotatably connected inside the slide rail bracket 3, and a clamping plate 301 slidably connected to the inner wall of the slide rail bracket 3. The clamping plate 301 is configured as two sets, and the clamping plate 301 is threadedly connected to the bidirectional screw 303. The locking groove 302 is used to lock the driving screw 203 to prevent shaking. After the clamping assembly completes the positioning of the pipe, the bidirectional screw 303 is rotated, and the two sets of clamping plates 301 are driven to slide towards each other along the slide rail bracket 3 through the threaded transmission. When the clamping plate 301 is closed, the locking groove 302 wraps around the outer wall of the screw 203 and restricts the rotation of the screw 203 through friction, preventing the pressing ring 204 from loosening due to vibration or external force.

[0030] In a preferred embodiment, a guide plate 4 is fixed to the lower inner wall of the guide groove 206, and a push block 401 is slidably connected to the lower end face of the guide plate 4. A pressing roller shaft 402 is rotatably connected to one end of the push block 401 near the upper end face of the lower pressure plate 404. An L-shaped bracket 5 is fixed to the side wall of the mounting bracket 2. A bolt 501 is threadedly connected to the inside of the L-shaped bracket 5. The bolt 501 is rotatably connected to one end of the push block 401. The pressing roller shaft 402 is used to push the lower pressure plate 404. The lower pressure plate 404 is located on both sides of the energy-concentrating tube inside the V-groove 201 for pressing and positioning.

[0031] Specifically, the rotating bolt 501 pushes the push block 401 to slide along the guide plate 4 through the threaded transmission, and the pressure roller shaft 402 pushes the lower pressure plate 404 to rotate around the rotating shaft. The lower end of the lower pressure plate 404 presses against the side wall of the pipe fitting to achieve lateral fixation.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] When using this energy-concentrating pipe fitting limiting and positioning device, firstly, place the energy-concentrating pipe fitting in the V-groove 201 at the upper end of the mounting bracket 2. The rubber pad on the inner wall of the V-groove 201 increases friction to achieve anti-slip. At the same time, the structural characteristics of the V-groove 201 are used to automatically center the pipe fitting, so that its central axis basically coincides with the expected positioning axis of the device, completing the initial radial positioning. Next, rotate the screw 203 connected by the vertical thread inside the top plate 202. The screw 203 moves downward and drives the pressing ring 204 connected to the lower end to move downward synchronously. The pressing ring 204 presses down and clamps the pipe fitting through the rubber bolts 205 evenly distributed on the contact surface. During this process, the guide rods 207 in the guide grooves 206 on both sides of the mounting bracket 2 slide with the pressing ring 204 to provide vertical guidance and ensure that the pipe fitting is subjected to uniform force.

[0034] Subsequently, the bolts 501 inside the L-shaped bracket 5 on the side wall of the rotating mounting bracket 2 are rotated, and the push block 401 is pushed along the guide plate 4 by the threaded transmission. The pressing roller shaft 402 at one end of the push block 401 pushes the lower pressure plate 404 on the support block 403 on the inner wall of the V-groove 201, so that the lower pressure plate 404 rotates around the rotating shaft, and its lower end presses the two side walls of the pipe fitting to achieve lateral fixation. Finally, after the clamping assembly is positioned, the bidirectional screw 303 inside the rotating slide rail bracket 3 is rotated, driving the two sets of clamping plates 301 threadedly connected to the bidirectional screw 303 to slide towards each other along the inner wall of the slide rail bracket 3 until the locking groove 302 on the inner wall of the clamping plate 301 wraps around the outer wall of the screw 203. The friction restricts the rotation of the screw 203 and prevents the pressing ring 204 from loosening due to vibration or external force, thereby completing the overall positioning of the energy-concentrating pipe fitting.
