Description

Technical Field

[0001] The invention relates to the technical field of tooling and fixtures, in particular to a tooling and fixture for processing military products. Background Art

[0002] Military products, also known as military products, are the opposite of "civilian products". They refer to material products used in military activities or used by the military. Military products can be divided into broad and narrow senses. In a narrow sense, they usually refer to weapons and equipment and other military-specific products. In a broad sense, they refer to all materials used by the military, including both military-specific products such as weapons and equipment, and military-civilian general-purpose products such as food, medicine, oil, and electromechanical products. Existing fixtures for processing military products have many defects in terms of fixing effect. On the one hand, existing fixtures use rigid fixing methods, such as simple mechanical clamping structures, to fix military products through bolts, nuts and other connectors. However, the fixtures lack the ability to adapt to military products of different weights. In actual production, the weight range of military products is relatively wide, ranging from lightweight electronic components to heavy mechanical parts. When fixing lighter military products, if the clamping force of the fixture is too large, it may cause indentations, scratches and other damages to the surface of the workpiece, affecting the appearance and performance of the product; and when fixing heavier military products, if the clamping force is insufficient, the stability of the workpiece during processing cannot be guaranteed, which will also lead to increased processing errors. Summary of the invention

[0003] The purpose of the present invention is to provide a tooling fixture for processing military products to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides a tooling fixture for processing military products, including a base and a clamping device, including: a clamping device, arranged above the base; a receiving plate, arranged above the base; a first airbag, fixedly installed on the top of the base, a mounting plate fixedly installed on the inner top wall of the first airbag, and reset parts fixedly installed on both sides of the first airbag, and the reset parts are set to be V-shaped spring steel; a ventilation pipe, fixedly installed on one side of the first airbag, and a second airbag fixedly installed on the other end of the ventilation pipe.

[0005] Furthermore, the clamping device includes a mounting block, a clamping plate is fixedly mounted on one side of the mounting block, a trapezoidal block is fixedly mounted on one side of the mounting block, a mounting frame extending from the bottom of the supporting plate is rotatably connected to a rotating roller, and the rotating roller is arranged above the trapezoidal block and abuts against the inclined surface of the trapezoidal block.

[0006] Furthermore, a plurality of rollers are rotatably connected to the inclined surface of the trapezoidal block, and the plurality of rollers are linearly arranged along the inclined surface.

[0007] Furthermore, it also includes a reset mechanism, which includes a plurality of telescopic tubes, which are fixedly installed between the inner bottom wall of the first airbag and the mounting plate, and the telescopic tubes are composed of a sleeve and a sliding tube, and a reset spring and a telescopic rod are fixedly installed between the sleeve and the sliding tube, and the reset spring is sleeved on the reset spring.

[0008] Furthermore, a guide groove is provided on the base, a slider matched with the guide groove is fixedly installed on the bottom of the trapezoidal block, a rolling wheel is arranged inside the sliding block, and the rolling wheel abuts against the guide groove.

[0009] Furthermore, the cross sections of the guide groove and the sliding block are both configured to be in an inverted T shape.

[0010] Furthermore, the receiving plate is provided with a plurality of sliding grooves, the inner walls of the sliding grooves are provided with two guide rods, and the mounting blocks are slidably connected to the outer walls of the guide rods.

[0011] Furthermore, a protective rubber layer is integrally formed on the top of the receiving plate, a tension spring is fixedly installed between the sliding block and the inner wall of the guide groove, and the tension spring is arranged inside the guide groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, military products are placed on the top of the receiving plate. The gravity of the military products drives the receiving plate to move downward and squeeze the first airbag. The gas inside the first airbag is transferred to the inside of the second airbag through the vent pipe. The second airbag expands and squeezes and fixes the two sides of the military products. If the weight of the military products is greater, the expansion degree of the airbags on both sides and the change of the internal gas pressure are directly related to the clamping force on the military products. When the expansion degree of the airbags on both sides increases, the contact area and the squeezing force on the military products will increase, thereby providing a greater clamping force. On the contrary, when the military products are lighter, the pressure on the bottom airbag is small, the gas transfer amount is small, the expansion degree of the airbags on both sides is small, and the clamping force is correspondingly reduced. The mechanism of automatically adjusting the clamping force according to the weight of the military products can not only accurately adapt to processing objects of different weights, but also cleverly avoid the damage to the military products caused by excessive or insufficient clamping force.

[0013] 2. In the present invention, military supplies are placed on the top of the receiving plate. The gravity of the military supplies causes the receiving plate to move downward together with the rotating roller. The rotating roller moves on the inclined surface of the trapezoidal block and presses the trapezoidal block downward. The rotating roller pushes the trapezoidal block to move toward the center of the base. The trapezoidal block drives the clamping plate to move to the middle position of the receiving plate through the mounting block, thereby fixing the military supplies.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 7 , the present invention provides a technical solution: See also Figure 1-Figure 7 The figure shows a tooling fixture for processing military products, including a base 1 and a clamping device 6, including: the clamping device 6 is arranged above the base 1; a receiving plate 2 is arranged above the base 1; a first airbag 3 is fixedly installed on the top of the base 1, a mounting plate is fixedly installed on the inner top wall of the first airbag 3, and reset members 13 are fixedly installed on both sides of the first airbag 3, and the reset member 13 is set to be a V-shaped spring steel; a ventilation pipe 4 is fixedly installed on one side of the first airbag 3, and a second airbag 5 is fixedly installed on the other end of the ventilation pipe 4.

[0018] When the military product is placed on the top of the receiving plate 2, its own gravity causes the receiving plate 2 to move downward, thereby squeezing the first airbag 3 at the bottom. During this process, the gas inside the first airbag 3 follows the pressure transfer principle and flows to the second airbag 5 through the ventilation pipe 4, causing the second airbag 5 to begin to expand, thereby exerting a squeezing effect on both sides of the military product to achieve a fixing effect.

[0019] The above structure has good adaptive characteristics. Changes in the weight of military products will directly cause corresponding adjustments to the clamping force of the airbags on both sides. When the military products being processed are heavier, the pressure applied to the bottom airbag increases, and the gas transfer amount increases accordingly, which significantly increases the expansion degree of the airbags on both sides. As the expansion degree increases, the contact area between the airbag and the military product is expanded, and the extrusion force is also enhanced simultaneously, thereby providing a stronger and more stable clamping force for the military product, effectively ensuring the stability of the heavier military products during the processing process.

[0020] On the contrary, if the military products are lighter, the pressure they exert on the bottom airbags is relatively small, and the amount of gas transfer is also reduced accordingly, which leads to limited expansion of the airbags on both sides and a weaker clamping force. This mechanism, which automatically adjusts the clamping force according to the weight of the military products, can not only accurately adapt to processing objects of different weights, but also cleverly avoid possible damage to military products due to excessive or insufficient clamping force. It greatly improves the reliability, stability and processing accuracy of tooling and fixtures in the processing of military products, laying a solid foundation for the high-quality and high-efficiency promotion of military production.

[0021] See also Figure 1-3 The clamping device 6 includes a mounting block 602, a clamping plate 601 is fixedly installed on one side of the mounting block 602, the second airbag 5 is fixedly installed on one side of the clamping plate 601, a trapezoidal block 604 is fixedly installed on one side of the mounting block 602, and a rotating roller 603 is rotatably connected to the mounting frame extending from the bottom of the receiving plate 2. The rotating roller 603 is arranged above the trapezoidal block 604 and abuts against the inclined surface of the trapezoidal block 604.

[0022] In the operation process of the tooling fixture, the military products to be processed are first placed stably on the top position of the receiving plate 2. At this time, due to the gravity of the military products themselves, the receiving plate 2 will produce a downward displacement movement, and the rotating roller 603 connected to the bottom of the receiving plate 2 will also move downward synchronously.

[0023] As the rotating roller 603 moves downward, it will contact the inclined surface of the trapezoidal block 604, and under the combined action of gravity and the inclined surface, it will roll along the inclined surface of the trapezoidal block 604. This rolling process will apply a downward pressure to the trapezoidal block 604, causing the trapezoidal block 604 to move horizontally on the plane below the receiving plate 2, and the movement direction is toward the center position of the base 1.

[0024] Since the trapezoidal block 604 is tightly connected to the mounting block 602, when the trapezoidal block 604 moves toward the center of the base 1, this movement will be transmitted to the splint 601 through the mounting block 602, so that the splint 601 begins to gradually approach the middle position of the receiving plate 2 and finally fits tightly. Through such a mechanical linkage mechanism, the splint 601 forms a stable clamping force on the military supplies placed on the receiving plate 2 from both sides, thereby achieving reliable fixation of the military supplies, providing a solid foundation for subsequent processing operations, ensuring that the military supplies can maintain a stable position during the processing, and effectively avoiding processing errors that may be caused by workpiece displacement, thereby ensuring the processing accuracy and quality requirements of the military supplies.

[0025] It should be noted that the military supplies can be removed by simply pulling the mounting block 602 to both sides.

[0026] See also Figure 6 A plurality of rollers are rotatably connected to the inclined surface of the trapezoidal block 604, and the plurality of rollers are linearly arranged along the inclined surface.

[0027] When the rotating roller 603 moves on the inclined surface of the trapezoidal block 604, direct contact with the inclined surface will generate a large friction force, and the presence of multiple rollers will convert sliding friction into rolling friction. The coefficient of rolling friction is much smaller than the coefficient of sliding friction, which makes the rotating roller 603 move more smoothly on the inclined surface of the trapezoidal block 604, reduces energy loss and component wear, and is beneficial to improving the service life and mechanical efficiency of the tooling fixture, ensuring that the fixture can operate stably and reliably during long-term and frequent use.

[0028] See also Figure 5 , and also includes a reset mechanism 7, which includes a plurality of telescopic tubes 701, which are fixedly installed between the inner bottom wall of the first airbag 3 and the mounting plate. The telescopic tubes 701 are composed of a sleeve and a sliding tube, and a reset spring 702 and a telescopic rod 703 are fixedly installed between the sleeve and the sliding tube, and the reset spring 702 is sleeved on the reset spring 702.

[0029] When the fixture completes the processing operation on military products, the mounting plate can quickly and accurately return to the initial position under the action of the reset mechanism 7. The arrangement of multiple telescopic tubes 701 allows the mounting plate to be subjected to uniform reset force in all directions, thus avoiding tilting or jamming of the mounting plate due to uneven force on one side. The structural coordination of the sleeve and the slide tube provides a stable guide for the reset of the mounting plate, ensuring that it moves along a predetermined trajectory, thereby accurately returning to the starting height and preparing for the next processing operation, greatly improving the accuracy and efficiency of the reuse of the fixture.

[0030] See also Figure 7 A guide groove 8 is provided on the base 1 , a slider 9 adapted to the guide groove 8 is fixedly installed on the bottom of the trapezoidal block 604 , a rolling wheel 10 is provided inside the slider 9 , and the rolling wheel 10 abuts against the guide groove 8 .

[0031] The cooperation between the guide groove 8 and the slider 9 provides a precise guide path for the movement of the trapezoidal block 604. In the process of clamping and fixing military products by the tooling fixture, the trapezoidal block 604 needs to move accurately in the predetermined direction to drive the clamp 601 to achieve stable and precise clamping of the workpiece. The sliding of the slider 9 in the guide groove 8 can effectively limit the freedom of the trapezoidal block 604, ensuring that it only moves in the designed direction, avoiding the deviation of the clamping of the military products by the clamp 601 due to the offset of the trapezoidal block 604, thereby improving the clamping accuracy of the tooling fixture and meeting the requirements of high-precision processing of military products.

[0032] The rolling wheel 10 arranged inside the slider 9 abuts against the guide groove 8, converting the sliding friction between the slider 9 and the guide groove 8 into rolling friction. The friction force of rolling friction is much smaller than that of sliding friction, which makes the trapezoidal block 604 smoother in the process of movement, reduces energy loss and component wear. On the one hand, it can make the operation of the tooling fixture easier and faster, and improve work efficiency; on the other hand, it reduces the degree of wear of components, helps to extend the service life of the tooling fixture, reduce the impact of frequent replacement of components on production progress and cost, and ensure the stability and continuity of the processing process of military products.

[0033] See also Figure 7 The cross sections of the guide groove 8 and the slider 9 are both set to be inverted T-shape.

[0034] The cross-sections of the guide groove 8 and the slider 9 are set to an inverted T shape. This shape design can effectively prevent the slider 9 from accidentally falling off the guide groove 8. During the operation of the tooling fixture, the trapezoidal block 604 frequently moves back and forth in the guide groove 8 through the slider 9 to achieve the clamping and releasing action of the clamp 601 on military supplies. The inverted T-shaped structure allows the slider 9 to be restricted in the guide groove 8 in the vertical direction. Even under large external force impact or complex vibration environment, the connection between the slider 9 and the guide groove 8 can be ensured to be firm, thereby ensuring the stability of the entire tooling fixture structure.

[0035] For the processing of military products, any slight displacement or looseness may lead to a decrease in processing accuracy. This inverted T-shaped design can effectively avoid tooling and fixture failure caused by the slider 9 detaching from the guide groove 8, providing a reliable guarantee for the high-precision processing of military products.

[0036] See also Figure 4 A plurality of sliding grooves 11 are provided on the receiving plate 2 , two guide rods 12 are installed on the inner wall of the sliding groove 11 , and the mounting block 602 is slidably connected to the outer wall of the guide rod 12 .

[0037] During the operation of the tooling fixture, the mounting block 602 needs to move stably and precisely to drive the clamp 601 to accurately clamp the military products. The guide rod 12 in the sliding groove 11 provides a clear movement path for the mounting block 602. When the mounting block 602 slides along the outer wall of the guide rod 12, the guide rod 12 strictly limits the movement direction of the mounting block 602 so that it can only move in a predetermined straight line direction. This precise guidance is more important for the processing of military products, because military products usually have extremely high requirements for processing accuracy. The precise clamping position can effectively reduce the processing error caused by the movement deviation of the fixture and ensure product quality.

[0038] The arrangement of multiple sliding grooves 11 and guide rods 12 can position the mounting block 602 from multiple directions. For example, on a two-dimensional plane, the guide rods 12 at different positions can work together to accurately determine the planar position of the mounting block 602, thereby precisely controlling the clamping position of the splint 601 on the military product, so that the splint 601 can accurately fit the side of the military product according to the design requirements, thereby achieving a stable and reliable clamping effect.

[0039] See also Figure 2-3 A protective rubber layer is integrally formed on the top of the receiving plate 2 , and a tension spring 14 is fixedly installed between the slider 9 and the inner wall of the guide groove 8 , and the tension spring 14 is arranged inside the guide groove 8 .

[0040] After the staff completes the process of taking military supplies and removes them from the receiving plate 2, the tension spring 14 immediately activates the reset mechanism. Relying on its own elastic potential energy, the tension spring 14 applies a pulling force to the trapezoidal block 604 connected to it, prompting the trapezoidal block 604 to move stably along the predetermined track in the direction away from the receiving plate 2. In this process, the trapezoidal block 604 uses the mounting block 602 as a transmission medium to accurately transmit the pulling force to the splint 601, thereby driving the splint 601 to gradually return to the initially set position. In this way, the entire device successfully completes a reset operation, and is fully prepared for the subsequent execution of the task of fixing military supplies, ensuring that it can quickly, efficiently and stably perform its fixing function the next time it is used, thereby ensuring the safety and stability of military supplies during circulation.

[0041] When placing and taking military supplies, scratches are easily generated due to contact. The protective rubber layer is soft in texture. When the military supplies come into contact with the receiving plate 2, the rubber layer can act as a buffer to prevent the surface of the military supplies from being scratched by the hard surface of the receiving plate 2. For some military supplies with high surface accuracy requirements and complex structures, such as high-precision optical instrument parts, precision missile guidance system components, etc., slight damage to the surface may affect their performance. The protective rubber layer can effectively protect the surface quality of these sensitive components.

[0042] During the processing, some unexpected vibrations or impact forces may occur, causing the military products to collide with the receiving plate 2. The elasticity of the rubber layer can absorb the energy generated by these collisions, reduce the impact on the military products, and reduce the risk of damage caused by collisions, such as loosening of the internal structure of the parts and surface deformation.
