Description

Technical Field

[0001] This invention relates to the field of metal processing machinery and equipment technology, and in particular to a processing device for a fire-fighting machinery emergency start cabinet. Background Technology

[0002] In fire protection systems, the emergency start cabinet for fire-fighting machinery is a critical piece of equipment. Its structural strength and assembly precision directly affect the reliability of emergency response. Currently, the clamping devices used in the metal machining of such cabinets are generally single-sided positioning or asynchronous clamping structures, which have revealed many shortcomings in actual metal machining production. Due to the lack of an effective centering mechanism, workpiece positioning is time-consuming and difficult to adapt to the rapid switching between different cabinet specifications; uneven clamping force distribution, coupled with rigid contact, easily causes surface damage or local deformation of the cabinet during metal machining, seriously affecting the product's appearance quality and subsequent assembly precision. These defects make it difficult for existing equipment to meet the dual requirements of metal machining efficiency and yield rate in multi-variety, small-batch production modes.

[0003] To mitigate the damage caused by rigid clamping during metal machining, some machining equipment has incorporated elastic clamping structures, attempting to absorb clamping impacts through the compression and deformation of spring elements. However, existing designs generally lack linear guiding constraints on the elastic clamping components, causing the springs to easily bend laterally or shift under pressure, leading to problems such as clamping sluggishness and reduced motion stability. This structural defect not only weakens the buffering effect of elastic clamping in metal machining but may also exacerbate the impact on the workpiece due to unstable movement, resulting in frequent equipment failures and increased maintenance costs after prolonged metal machining operation.

[0004] In summary, existing metal machining devices for fire-fighting emergency start cabinets have significant shortcomings in clamping and centering accuracy, dimensional compatibility, and operational stability, making it difficult to simultaneously meet the dual requirements of efficient metal machining and non-destructive clamping. Problems such as slow clamping response, poor adaptability to various cabinet sizes, and easy misalignment of elastic elements collectively restrict the improvement of metal machining production efficiency and the guarantee of product consistency. Therefore, there is an urgent need to develop a new type of metal machining device with rapid centering, self-adaptive clamping, and stable guidance to overcome current technological bottlenecks and meet the urgent needs of the fire-fighting equipment manufacturing industry for high-quality, high-efficiency metal machining. Summary of the Invention

[0005] This invention aims to solve the problems of low centering efficiency, poor size compatibility, uneven clamping force that easily damages the workpiece, and lack of linear guidance in the elastic clamping components that leads to motion jamming and insufficient operational stability in existing fire-fighting machinery emergency start cabinet processing devices. It provides a fire-fighting machinery emergency start cabinet processing device that can achieve efficient synchronous centering, adaptive flexible clamping, and stable and reliable guidance.

[0006] To achieve the aforementioned objectives, the specific solution of this invention is as follows: a processing device for a fire-fighting mechanical emergency start cabinet, comprising a movable worktable, the lower end of which is slidably connected to the upper end of a base, symmetrical fixing blocks fixedly installed on the upper end of the movable worktable, a rotatably connected opposing lead screws passing through the fixing blocks, one end of the opposing lead screws being connected to the output end of a motor via a coupling, symmetrical nut seats fitted onto the opposing lead screws, a corresponding first guide rod slidably connected to the other end of the symmetrical nut seats, a corresponding clamping block fixedly installed on one end of the symmetrical nut seats, and a movable connecting rod mounted on the corresponding clamping block. The device comprises three corresponding first connecting rings, each with a corresponding first through hole and a second through hole. Each corresponding clamping block has three corresponding guide holes and threaded holes. A corresponding second guide rod is slidably connected within each of the three corresponding guide holes. Each second guide rod is movably connected to its corresponding first through hole. The upper end of each second guide rod is fixedly connected to the lower end of its corresponding second connecting ring. A corresponding spring is fixedly installed at the lower end of each second connecting ring, and the lower end of each spring is fixedly installed at the upper end of its corresponding first connecting ring. This invention achieves synchronous, opposite-facing movement of the two clamping blocks through the cooperation of opposing lead screws and symmetrical nut seats, improving the speed and accuracy of workpiece alignment. Simultaneously, the elastic clamping assembly formed by the second guide rods, springs, and the first and second connecting rings provides cushioning during clamping, effectively preventing damage to the cabinet surface caused by rigid clamping and laying the foundation for subsequent high-precision machining.

[0007] According to the processing device for a fire-fighting machinery emergency start cabinet of the present invention, each of the three corresponding second through holes is movably connected to a corresponding screw, and each corresponding screw is threaded into a corresponding threaded hole for detachably fixing the first connecting ring to the clamping block. Here, the connection between the screw and the threaded hole achieves detachable fixing of the first connecting ring to the clamping block. This structure facilitates quick replacement of elastic clamping components of different specifications or wear according to different processing requirements, improving the device's maintenance convenience and adaptability to different workpieces.

[0008] According to the present invention, a processing device for a fire-fighting machinery emergency start cabinet includes a groove on the movable worktable, within which a roller is installed. The upper end of the roller carries the workpiece. Symmetrical baffles are installed at both ends of the upper part of the movable worktable away from the groove to limit the lateral displacement of the workpiece. By providing grooves and rollers on the movable worktable, the frictional resistance of the workpiece during loading and unloading is reduced, the operator's labor intensity is lowered, and production efficiency is improved. The symmetrically arranged baffles can initially limit the workpiece before clamping, preventing it from shifting during movement and ensuring accurate starting position for centering and clamping.

[0009] According to the present invention, a processing device for a fire-fighting machinery emergency start cabinet includes symmetrical rubber pads movably connected to the upper end of the rollers. A corresponding connecting plate is fixedly installed at one end of each symmetrical rubber pad, and three corresponding second connecting rings are fixedly installed at the other end of each corresponding rubber pad to provide flexible contact during clamping. The rubber pads further enhance the clamping flexibility, increase the contact area with the workpiece surface, and effectively disperse the clamping force. For fire cabinets with high surface finish requirements, they can minimize indentations or scratches. The design of the connecting plates ensures a stable connection between the rubber pads and the clamping structure.

[0010] According to the present invention, a processing device for a fire-fighting mechanical emergency start cabinet is provided at the upper end of the base, and a drill bit is provided at one end of the processing mechanism for drilling holes in the clamped and fixed cabinet. This solution integrates the processing mechanism and its drill bit onto the base, forming an integrated layout with the clamping device. This design ensures the consistency between the drilling position and the clamping positioning reference, reduces repeated positioning errors, thereby improving the positional accuracy of the drilled holes on the cabinet and guaranteeing product quality.

[0011] According to the processing device for a fire-fighting machinery emergency start cabinet of the present invention, the second guide rod and the guide hole are clearance-fitted, and the spring is sleeved on the outside of the second guide rod, with its two ends respectively abutting against the first connecting ring and the second connecting ring. The clearance fit between the second guide rod and the guide hole provides precise linear guidance for the compression and release of the spring, eliminating the risk of lateral bending and deviation of the spring. At the same time, the spring sleeved on the outside of the guide rod has a compact structure, ensuring smooth and stable elastic clamping action and improving the long-term reliability of the device.

[0012] According to the present invention, a processing device for a fire-fighting mechanical emergency start cabinet includes a lead screw comprising two sections of external threads with opposite directions, which respectively cooperate with two nut seats to achieve synchronous opposite or backward movement of the two clamping blocks. By employing a lead screw containing two sections of external threads with opposite directions, the present invention achieves strictly synchronous movement of the two clamping blocks under a single power input. This mechanical synchronization method has higher centering accuracy and control stability than independent drive or asynchronous structures, ensuring the coincidence of the workpiece center and the processing center, and is particularly suitable for cabinet processing with high symmetry requirements.

[0013] This invention also introduces a method for processing a fire-fighting mechanical emergency start cabinet using the above-described device, comprising the following steps: Step 1, placing the cabinet to be processed on the rollers of the movable worktable and starting the motor; Step 2, the motor drives the opposing lead screws to rotate, causing the two nut seats to slide towards each other along the first guide rod until the rubber pad on the clamping block contacts the surface of the cabinet; Step 3, continuing to drive the clamping block to move, causing the spring to be compressed and generating a preload, and achieving linear guidance by sliding along the guide hole through the second guide rod, thus completing the flexible adaptive clamping of the cabinet.

[0014] The above method integrates workpiece positioning, clamping, and elastic preloading into a coherent automated process. Through a two-step clamping strategy of first contacting and then applying pressure, it not only ensures the reliability of clamping but also utilizes the preload force of the spring to achieve flexible adaptive clamping. This solves the problems of difficult clamping force control and easy workpiece damage in traditional methods, thereby improving processing efficiency and yield.

[0015] The optimization of the above-mentioned processing method for the anti-mechanical emergency start cabinet also includes step four: adjusting the relative distance between the first connecting ring and the clamping block by turning the screw according to the thickness of the cabinet side wall, thereby adjusting the initial compression of the spring and changing the preset value of the clamping force of the clamping mechanism. This solution, through the step of adjusting the initial compression of the spring by turning the screw, gives the processing method extremely high process flexibility. Operators can quickly and quantitatively preset the clamping force according to the material, wall thickness, and processing strength requirements of different cabinets, realizing rapid changeover and refined processing of multiple specifications of products on the same production line, thus expanding the applicability of the equipment.

[0016] The optimization of the above-mentioned machining method for the anti-mechanical emergency start cabinet also includes step five: After machining is completed, the motor is started in reverse, causing the opposing lead screws to drive the two clamping blocks to move in opposite directions; during this process, the spring gradually releases its elastic force, and the second guide rod retracts within the guide hole until the clamping blocks are completely detached from the cabinet, and then the machined cabinet is moved out along the rollers. This invention designs a controlled, buffered clamping release step after machining, where the release of the spring force is synchronized with the backward movement of the clamping blocks, avoiding workpiece displacement or overturning due to sudden clamping release. The entire loading and unloading process is smooth, safe, and efficient, forming a complete closed loop from loading to clamping to machining to clamping to unloading, optimizing the production cycle and improving the automation level of the production line.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The metal machining device for the fire-fighting emergency start cabinet of the present invention uses a motor to drive the opposing lead screw to rotate, which drives two clamping blocks to move synchronously towards each other, realizing rapid centering and positioning of the workpiece, shortening the centering time and improving the production efficiency of metal machining. At the same time, the device introduces a spring assembly and a rubber pad between the clamping block and the workpiece to form a two-stage flexible buffer mechanism. When the clamping block contacts the workpiece, the spring is compressed to generate an adaptive clamping force, which can automatically adjust the clamping stroke according to the changes in workpiece size, and effectively absorb the clamping impact during the metal machining process, avoiding damage to the cabinet surface caused by rigid contact. The addition of the rubber pad further disperses the clamping pressure and enhances the friction, improving the clamping stability while protecting the workpiece surface. This structural design allows the same device to be compatible with the metal machining needs of cabinets of various specifications, improving the versatility and flexible production capabilities of the equipment.

[0018] 2. To ensure the reliability of the elastic clamping assembly during repeated operations, this device features precisely drilled guide holes on the clamping block, which slide in conjunction with the second guide rod. This provides strict linear motion constraints for the compression and release of the spring. When the spring is compressed, the second guide rod always slides axially along the guide hole, effectively limiting the radial offset and lateral bending of the spring. This eliminates the problem of motion jamming caused by spring instability in traditional elastic clamping structures. This precision guide design not only ensures the smoothness and stability of the clamping action during metal machining but also allows the clamping force to be applied evenly and vertically to the side of the workpiece, avoiding workpiece displacement or tilting caused by uneven force. This provides a stable and reliable positioning basis for subsequent metal machining processes.

[0019] 3. This invention, through the organic combination of a synchronous centering mechanism and a linear guide elastic clamping system, constructs a metal machining device that integrates high-efficiency, stable, and non-destructive clamping. The opposing lead screw structure solves the centering efficiency problem when switching between multiple specifications, while the precise fit between the guide hole and the second guide rod improves the dynamic operation quality of the elastic clamping, enabling the device to maintain excellent performance consistency even under long-term, high-frequency metal machining production rhythms. This structural design not only meets the stringent requirements of uniform clamping force and positioning accuracy in the metal machining of fire emergency start cabinets, but also effectively ensures the product's appearance quality through flexible contact, providing reliable technical support for improving metal machining production efficiency and yield.

[0022] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0023] like Figures 1-5As shown, this invention introduces a processing device for a fire-fighting machinery emergency start cabinet, including a movable worktable 1. The lower end of the movable worktable 1 is slidably connected to the upper end of a base 2, allowing the movable worktable 1 to move smoothly along the base 2, facilitating precise positioning and adjustment of the processing position. Symmetrical fixing blocks 5 are fixedly installed on the upper end of the movable worktable 1. Opposing lead screws 9 are rotatably connected through the fixing blocks 5. Each opposing lead screw 9 includes two external threads with opposite directions, respectively engaging with two nut seats 11. One end of the opposing lead screw 9 is connected to the output end of a motor 6 via a coupling, and is driven to rotate by the motor 6. Symmetrical nut seats 11 are connected to the opposing lead screw 9. A corresponding first guide rod 10 is slidably connected to the other end of each symmetrical nut seat 11. The first guide rod 10 provides guiding support for the axial movement of the nut seat 11, ensuring smooth operation. One end of the symmetrical nut seat 11 is fixedly installed with a corresponding clamping block 15. When the motor 6 drives the opposing lead screw 9 to rotate, the two nut seats 11 drive the two clamping blocks 15 to move synchronously towards or away from each other, thereby completing the rapid centering clamping or releasing of the workpiece.

[0024] The clamping block 15 is equipped with an elastic component for flexible clamping. Specifically, three corresponding first connecting rings 19 are movably connected to the corresponding clamping block 15. Each of the three corresponding first connecting rings 19 has a corresponding first through hole 20 and a second through hole 21. Each of the corresponding clamping blocks 15 also has three corresponding guide holes 13 and threaded holes 14. A corresponding second guide rod 24 is slidably connected within each of the three corresponding guide holes 13. The second guide rod 24 and the guide hole 13 are clearance-fitted to ensure smooth sliding without lateral displacement. Each corresponding second guide rod 24 is movably connected within its corresponding first through hole 20, meaning the second guide rod 24 passes through the first through hole 20 and can move relative to it. The upper end of each corresponding second guide rod 24 is fixedly connected to the lower end of its corresponding second connecting ring 22. A corresponding spring 23 is fixedly installed at the lower end of each corresponding second connecting ring 22, and the lower end of each spring 23 is fixedly installed at the upper end of its corresponding first connecting ring 19. Spring 23 is sleeved on the outside of second guide rod 24, with its two ends abutting against first connecting ring 19 and second connecting ring 22 respectively, forming an elastic buffer structure. When clamping block 15 moves towards the workpiece, second connecting ring 22 contacts the workpiece first. As clamping block 15 continues to advance, spring 23 is compressed, and second guide rod 24 slides along guide hole 13, providing precise linear guidance for the compression of spring 23, effectively preventing spring 23 from bending, shifting, or jamming, and ensuring smooth and stable clamping action.

[0025] To facilitate the installation and maintenance of the elastic components, corresponding screws 18 are movably connected to the three corresponding second through holes 21. Each screw 18 is threaded into a corresponding threaded hole 14, used to detachably fix the first connecting ring 19 to the clamping block 15. By tightening the screws 18, operators can quickly disassemble and assemble the elastic clamping components, facilitating replacement according to workpiece specifications or wear conditions. The relative distance between the first connecting ring 19 and the clamping block 15 can also be adjusted by regulating the screw depth of the screws 18, thereby changing the initial compression of the spring 23 and achieving preset and adjustable clamping force.

[0026] The movable worktable 1 has a groove 7, and a roller 8 is installed in the groove 7. The upper end of the roller 8 is used to support the workpiece. The roller 8 reduces the frictional resistance when loading and unloading the workpiece, reduces the labor intensity of the operator, and improves production efficiency. Symmetrical baffles 12 are provided at the two ends of the upper end of the movable worktable 1 away from the groove 7. These baffles are used to initially limit the workpiece before clamping, preventing lateral displacement during movement and ensuring accurate starting position of the clamping. Symmetrical rubber pads 17 are movably connected to the upper end of the roller 8. A corresponding connecting plate 16 is fixedly installed at one end of the symmetrical rubber pad 17, and three corresponding second connecting rings 22 are fixedly installed at the other end of the corresponding rubber pad 17. The rubber pad 17 serves as a flexible contact layer between the clamping block 15 and the workpiece, which can further disperse the clamping pressure, increase friction, effectively avoid indentation or scratches on the cabinet surface, and enhance the stability of clamping.

[0027] The upper end of the base 2 is provided with a processing mechanism 3, and one end of the processing mechanism 3 is provided with a drill bit 4 for drilling the clamped and fixed cabinet. The processing mechanism 3 and the clamping device are integrated on the same base 2, which ensures the consistency between the processing position and the clamping positioning reference, reduces repeated positioning errors, and thus improves the positional accuracy of drilling.

[0028] The working principle of the fire-fighting machinery emergency start cabinet processing device of the present invention is as follows: During operation, the fire-fighting emergency start cabinet body to be processed is first placed on the rollers 8 of the movable workbench 1. The baffle 12 is used to initially limit the lateral movement of the cabinet body, ensuring that the cabinet body is in the correct starting position within the clamping area. The motor 6 is started, and the motor 6 drives the opposing lead screw 9 to rotate through the coupling. Since the opposing lead screw 9 contains two external threads with opposite directions of rotation, they respectively cooperate with two nut seats 11. When the lead screw rotates, the two nut seats 11, under the guidance of their respective first guide rods 10, drive the two clamping blocks 15 to move synchronously towards each other along the axial direction of the first guide rods 10, thereby achieving rapid centering and positioning of the cabinet body.

[0029] As the clamping block 15 continues to move towards the cabinet, the rubber pad 17 fixed to the second connecting ring 22 first contacts the cabinet surface. At this time, the clamping block 15 continues to advance, and the second connecting ring 22 and the rubber pad 17 in contact with the cabinet surface are subjected to the reaction force of the cabinet, causing the spring 23 sleeved on the outside of the second guide rod 24 to begin to compress. During this process, the upper end of the second guide rod 24 is fixedly connected to the lower end of the second connecting ring 22, while the rod body of the second guide rod 24 passes through the first through hole 20 on the first connecting ring 19 and slides precisely axially along the guide hole 13 on the clamping block 15. The clearance fit between the guide hole 13 and the second guide rod 24 provides a strict linear motion constraint for the compression of the spring 23, effectively preventing the spring 23 from bending or shifting laterally, ensuring that the clamping action is smooth and without jamming.

[0030] When the spring 23 is compressed to the preset preload, the clamping block 15 stops advancing. At this point, the cabinet is firmly and securely clamped and fixed without damage under the flexible contact of the rubber pad 17 and the elastic pressure of the spring 23. The rubber pad 17 further disperses the clamping pressure, protecting the cabinet surface from damage, while increasing friction to enhance clamping stability. Subsequently, the processing mechanism 3 located on the upper end of the base 2 is activated, and its drill bit 4 performs drilling and other processing operations on the clamped and fixed cabinet.

[0031] After processing, motor 6 starts in reverse, driving the opposing lead screw 9 to rotate in the opposite direction. The two nut seats 11 drive the two clamping blocks 15 to move synchronously in opposite directions. During this process, spring 23 gradually releases its elastic force, pushing the second connecting ring 22 and rubber pad 17 to return smoothly to their original positions as the clamping blocks 15 move in opposite directions. The second guide rod 24 retracts synchronously along the guide hole 13 until the clamping blocks 15 are completely detached from the cabinet. Finally, the processed cabinet is moved out along roller 8, completing a full processing cycle.

[0032] like Figure 6 As shown, the present invention also provides a method for processing a fire-fighting mechanical emergency start cabinet using the above-mentioned device, comprising the following steps: Step 1: Place the cabinet to be processed on the rollers 8 of the movable worktable 1. The low friction of the rollers 8 makes it easy to load the cabinet. At the same time, the symmetrical baffles 12 set at both ends of the upper part of the movable worktable 1 away from the groove 7 provide initial lateral limitation for the cabinet, ensuring that the cabinet is in the correct starting position within the clamping area. Then start the motor 6.

[0033] In step two, motor 6 drives the opposing lead screw 9 to rotate via a coupling. Since the opposing lead screw 9 contains two external threads with opposite directions, each engaging with a nut seat 11, when the lead screw rotates, the two nut seats 11, guided by their respective first guide rods 10, drive the two clamping blocks 15 to slide synchronously towards each other along the axial direction of the first guide rods 10, achieving rapid centering and positioning of the cabinet until the rubber pad 17 fixedly installed on the clamping block 15 via the connecting plate 16 contacts the cabinet surface. This synchronous centering structure allows the cabinet center to quickly coincide with the machining center, significantly shortening the centering time.

[0034] Step 3: After the rubber pad 17 contacts the cabinet surface, the clamping block 15 continues to move towards the cabinet. At this time, the second connecting ring 22 and the rubber pad 17, which are in contact with the cabinet surface, are subjected to the reaction force of the cabinet, causing the spring 23, which is sleeved outside the second guide rod 24, to be compressed and generate a preload. During this process, the upper end of the second guide rod 24 is fixedly connected to the lower end of the second connecting ring 22, and the rod body of the second guide rod 24 passes through the first through hole 20 on the first connecting ring 19 and slides precisely axially along the guide hole 13 opened on the clamping block 15. The clearance fit between the second guide rod 24 and the guide hole 13 provides a strict linear motion constraint for the compression of the spring 23, effectively preventing the spring 23 from bending laterally, shifting, or jamming, and ensuring a smooth and stable clamping action. As the spring 23 is compressed to the preset preload state, the cabinet is firmly clamped under the flexible contact of the rubber pad 17 and the elastic pressure of the spring 23, completing the flexible adaptive clamping of the cabinet. This process implements a two-step clamping strategy of first contacting and then applying pressure, which not only ensures the reliability of clamping, but also utilizes the preload of the spring to achieve adaptive adjustment of the clamping force.

[0035] Step four: Before clamping or when changing to different cabinet specifications, adjust the relative distance between the first connecting ring 19 and the clamping block 15 by turning the screw 18, according to the thickness of the cabinet sidewall and the processing requirements. Specifically, the screw 18 is movably connected to the second through hole 21 on the first connecting ring 19 and threadedly connected to the threaded hole 14 on the clamping block 15, detachably fixing the first connecting ring 19 to the clamping block 15. By turning the screw 18 to adjust its screwing depth, the relative position between the first connecting ring 19 and the clamping block 15 can be changed, thereby adjusting the initial compression of the spring 23 and achieving precise adjustment of the preset value of the clamping force of the clamping mechanism. This step gives the processing method a high degree of process flexibility, enabling the operator to quickly and quantitatively preset the clamping force according to the material, wall thickness and processing strength requirements of different cabinets, and realize rapid changeover and fine processing of multiple specifications of products on the same production line.

[0036] Step 5: After the processing mechanism 3 completes drilling and other processing operations on the cabinet using drill bit 4, the motor 6 is started in reverse, causing the opposing lead screws 9 to rotate in the opposite direction. This drives the two nut seats 11 to move the two clamping blocks 15 synchronously in opposite directions. During this process, the spring 23 gradually releases its stored elastic force, pushing the second connecting ring 22 and the rubber pad 17 back to their original positions smoothly as the clamping blocks 15 move in opposite directions. The second guide rod 24 retracts synchronously within the guide hole 13 until the clamping blocks 15 are completely detached from the cabinet. The entire detachment process is controlled and buffered, preventing workpiece displacement or overturning due to sudden detachment. Finally, the processed cabinet is easily moved out along the rollers 8, completing a full processing cycle.

[0037] The above method, through the organic combination of synchronous centering mechanism and linear guide elastic clamping, constructs a processing flow that integrates high efficiency, stability and non-destructive clamping. From the smoothness of loading and unloading, the flexible self-adaptation of the clamping process, to the adjustable preset clamping force, and then to the smooth and controlled release of clamping, a complete closed loop from "loading-clamping-processing-release-unloading" is formed. This effectively solves the problems of difficult clamping force control, low centering efficiency and easy damage to workpieces in traditional methods, and improves production efficiency and product yield.

[0038] In summary, this invention addresses the problems of low centering efficiency, poor dimensional compatibility, uneven clamping force that easily damages the workpiece, and insufficient operational stability caused by the lack of linear guidance in the elastic clamping components. It proposes a structurally optimized and functionally integrated processing device and method. This device uses a movable worktable as its base, driving symmetrical nut seats and clamping blocks to move synchronously in opposite directions via opposing lead screws, achieving rapid centering of the workpiece. The clamping blocks integrate a precision-fitting structure of guide holes and a second guide rod, providing strict linear motion constraints for the compression and release of the spring, fundamentally eliminating the risk of lateral bending and jamming of the elastic clamping components. Simultaneously, the device allows for detachable installation of the elastic components through the connection between the screw and the threaded hole, providing adjustable clamping force, while the rubber pad further enhances the flexible protection of the workpiece surface. The accompanying processing method integrates material feeding, synchronous centering, flexible adaptive clamping, preset clamping force adjustment, and controlled loosening into a complete closed-loop process. This achieves a two-step clamping strategy of contact followed by pressure, making the clamping process both efficient and stable. Overall, this invention, through the organic combination of a synchronous centering mechanism and linearly guided elastic clamping, constructs a technical solution that integrates efficient, stable, and non-destructive clamping. It effectively resolves the contradiction between versatility and reliability in the processing of multi-specification cabinets, improves production efficiency and product quality, and provides solid technical support for the automated processing of fire-fighting mechanical emergency start cabinets.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
