Description

Technical Field

[0001] The invention relates to the technical field of gun and bullet product charging, and in particular to a continuous gun and bullet constant volume charging device suitable for use in production lines of various types of guns and bullets. Background Art

[0002] The assembly of bullets in the production process is a crucial link, which directly affects the quality and safety of bullets. During the production and assembly of bullets, a certain amount of propellant needs to be loaded into the shell.

[0003] In the prior art, the charge of propellant is mainly charged by weighing or fixed volume. The weighing method requires the propellant to be weighed before charging, and then charged after the weighing is qualified, so there is a disadvantage of low production efficiency. In order to improve production efficiency, the fixed volume method is usually adopted.

[0004] The method of constant volume and quantity is to first put the propellant into the constant volume device, and then transfer it to the cartridge case after the constant volume device is filled with propellant. Since the weighing steps are reduced, higher production efficiency can be achieved. However, with the changing demand for bullet production, various units have put forward higher requirements for the intelligence and flexibility of bullet production lines.

[0005] like Figure 6 As shown, the working mode of a typical continuous constant volume charging device in the prior art includes:

[0006] The main shaft 1001 drives the bullet feeding turntable 1002, the charge turntable 1003, and the metering plate 1004 to rotate at a constant speed. The cartridge case enters the notch of the bullet feeding turntable tangentially at the feeding position. As the turntable rotates, the first cam follower 1005 falls, and the drug guiding assembly 1006 presses the cartridge case. When the hole on the metering plate passes through the drug pool of the upper pressing plate 1007, the drug flows into it. As the turntable continues to rotate, the hole and the drug pool are cut off, and then communicated with the lower leak plate 1008. The drug flows into the cartridge case through the opening of the leak plate through the funnel 1009 and the drug guiding assembly, and the drug charging is completed. As the turntable continues to rotate, the drug guiding assembly rises, and the cartridge case is sent out tangentially from the discharge position.

[0007] Since the above scheme adopts an integrated metering plate, the size of the metering plate is large and the production change speed is slow. When it is necessary to charge different types of bullets, it is necessary to replace the fixed volume metering plate, funnel mold, and components used for positioning constraints, etc., and many parts need to be disassembled and assembled. At the same time, the equipment needs to be re-debugged after the production change, and it takes a long time to restore production efficiency. In addition, it does not have logical functions, and cannot determine whether there is raw material input to control the supply of medicine. When there is a shortage of shells, it needs to be stopped and replenished manually, and it takes a long time before and after stable production. Summary of the invention

[0008] In view of the above problems, the present invention provides a continuous gun bullet constant volume charging device for overcoming the above problems or at least partially solving the above problems. The device realizes the automatic charging process of the shells, and can achieve rapid production change through modular design. At the same time, it can determine whether there is a shell input, avoid the spilling of the powder or the shutdown when the previous feeding mechanism fails, improve the efficiency of the equipment, and improve the safety of the equipment.

[0043] A module mounting seat 4, wherein the module mounting seat 4 is sleeved on the outside of the stem 1 and can rotate relative to the stem 1, and the module mounting seat 4 is located above the guide frame 31 and is fixedly connected to the guide frame 31;

[0044] A medicine pool unit 5, wherein the medicine pool unit 5 is sleeved on the outside of the stem 1 and can rotate relative to the stem 1, and the medicine pool unit 5 is located above the module mounting seat 4 and is fixedly connected to the module mounting seat 4;

[0045] A plurality of charging modules 6, wherein the charging modules 6 are arranged in a ring around the core column 1 and are detachably connected to the module mounting seat 4; the charging module 6 comprises a base 61, a lower punch 62, a metering plate 63, a funnel 64, a cover plate 65 and a floating joint 66; the lower punch 62 is cooperatively connected with the base 61 and can slide along the axial direction of the core column 1 relative to the base 61, and the floating joint 66 is connected to the bottom of the lower punch 62; after the base 61 is connected with the cover plate 65, a slide groove extending along the axial direction of the core column 1 is formed, and after the metering plate 63 is connected with the funnel 64, it is cooperatively connected to the slide groove and can slide along the slide groove; the base 61 is provided with a drug supply channel 67 and a lower channel 68 separated from each other, the drug supply channel 67 is connected with the interior of the drug pool unit 5, and the metering plate 63 is provided with a metering chamber 69;

[0046] The floating joints 66 included in each of the charging modules 6 are connected to a plurality of the cam sliders 32 one by one, so that the cam sliders 32 drive the lower punch 62 to slide along the axial direction of the stem 1; the top of the stem 1 is used to accommodate a cartridge case 11 to be charged with powder with its opening facing upwards;

[0047] During the process of the lower punch 62 carrying the cartridge case 11 to be loaded rising, the cartridge case 11 to be loaded is connected to the funnel 64 and pushes the funnel 64 and the metering plate 63 to rise so that the medicine supply channel 67 is connected to the metering chamber 69, so that the propellant in the medicine pool unit 5 passes through the medicine supply channel 67 and fills the metering chamber 69; during the process of the lower punch 62 carrying the cartridge case 11 to be loaded descending, the funnel 64 and the metering plate 63 descend under the action of gravity or a spring so that the metering chamber 69 is separated from the medicine supply channel 67, and is connected to the lower channel 68 so that the propellant in the metering chamber 69 is loaded into the cartridge case 11 to be loaded through the funnel 64.

[0048] The continuous gun bullet constant volume charging device of the embodiment of the present invention adopts a core column 1 as a supporting component, uses a lower cam 2 as a driving component that moves axially along the core column 1, and is composed of a rotor structure composed of a guide unit 3, a module mounting seat 4, a medicine pool unit 5, etc. During the rotation of the rotor structure, the lower punch 62 can drive the cartridge case to reciprocate axially along the core column 1 under the action of the cam slider 32 and the lower cam 2. The logical function is realized through structural design. Only when there is a cartridge case input, the metering plate 63 will be lifted to the working position, filled with propellant, and the constant volume charging is completed. At the same time, the charging module 6 and the module mounting seat 4 in the main rotor seat are detachably connected through a universal interface. When charging cartridge cases with different charging requirements, only the charging module 6 and the restraining edge guard are replaced to complete the production change.

[0049] It is understandable that different cartridge cases have different requirements for the amount of charge. If the size difference between the two cartridge cases is relatively large, it is necessary to directly replace all the charge modules 6 to complete the production change. When charging some cartridge cases with small size differences and small charge amounts, since the charge amount each time is the amount of propellant that can be stored in the metering chamber 69, the volume of the metering chamber 69 of the installed charge module 6 can be changed to adapt to the requirements of different charge amounts. In order to adjust the volume of the metering chamber 69, the embodiment of the present invention can provide that the charge module 6 also includes an adjustment plate 610, the adjustment plate 610 is connected to the metering plate 63, and the metering chamber 69 is formed at the position where the adjustment plate 610 is connected to the metering plate 63, so as to adjust the positional relationship between the metering plate 63 and the adjustment plate 610, so as to change the charge amount of the metering chamber 69. The metering chamber 69 is formed by connecting the adjusting plate 610 and the metering plate 63. By adjusting the installation positions of the metering plate 63 and the adjusting plate 610, the volume of the metering chamber 69 can be adjusted, thereby achieving the purpose of adjusting the charge amount.

[0050] The charge unit provided by the present invention can be used as a container for storing propellant. In order to facilitate the addition of propellants, the present invention can provide that the charge pool unit includes a charge pool, which is mounted on the outside of the core column 1 and can rotate relative to the core column 1, and the charge pool is fixedly connected to the module mounting seat 4.

[0051] Since all rotating parts included in the device provided by the present invention need to rotate synchronously, it is necessary to drive the rotor structure to rotate synchronously. In order to facilitate connection with the driving device, the embodiment of the present invention can provide a driving gear 7, which is sleeved on the outside of the core column 1 and fixedly connected to the medicine pool through the connecting tube 8; the driving gear 7 is used to connect with the driver so as to drive the medicine pool and all parts connected to the medicine pool that can rotate relative to the core column 1. The driving gear 7 includes an outer toothed disc, which can be meshed with a power output gear of a driver that is meshed with it. For example, the driver can be an electric motor, and a corresponding power output gear is provided on the driving shaft of the electric motor. The power output gear is meshed with the driving gear 7, and the driving gear 7 can be driven to rotate by starting the electric motor. Since all rotatable parts included in the rotor structure are connected to the driving gear 7, all rotatable parts of the rotor structure rotate synchronously with the rotation of the driving gear 7.

[0052] In order to achieve the medicine supply effect of the medicine pool, the embodiment of the present invention further provides that the medicine pool is provided with a plurality of medicine supply holes, and the plurality of medicine supply holes are connected to the medicine supply channels 67 respectively included in the plurality of medicine loading modules 6 .

[0053] Furthermore, the medicine pool includes an annular medicine groove, and a plurality of medicine supply holes are arranged at the bottom of the annular medicine groove.

[0054] In order to realize the continuous supply of propellant into the medicine pool, the embodiment of the present invention can also provide a medicine supply pipe 9, one end of which passes through the driving gear 7 and the connecting tube 8 and extends into the medicine pool. The medicine supply pipe 9 is arranged in the cavity position of the driving gear 7 and the connecting tube 8, so when the driving gear 7 and other components rotate, the medicine supply pipe 9 will not interfere with the rotating components.

[0055] The guide frame 31 provided by the present invention is used to install and fix the cam slider 32, so that the cam slider 32 can finally drive the lower punch 62 to move up and down during the movement along the cam groove 21. Since the lower cam 2 is always in a fixed state, the guide frame 31 needs to drive the cam slider 32 to rotate around the core column 1. In order to achieve the synchronous rotation of the guide frame 31 and the module mounting seat 4, the guide frame 31 is fixedly connected to the module mounting block. In order to facilitate the connection between the two, the embodiment of the present invention can also provide that the guide frame 31 is connected to the module mounting seat 4 through the spoke plate 10.

[0056] The cam slider 32 is guided and fixed by the guide shaft 311 . In order to ensure the stability of the guidance, the embodiment of the present invention can also provide that each of the cam sliders 32 is connected by two guide shafts 311 .

[0057] In specific implementation, the embodiment of the present invention can also provide that the cam slider 32 includes a follower bearing seat 321, a follower shaft 322, a cam follower 323 and a linear bearing 324; the follower shaft 322 is fixedly connected to the side of the follower bearing seat 321, the cam follower 323 is cooperatively connected to the follower shaft 322, and the linear bearing 324 is used to cooperate with the guide shaft 311; the cam follower 323 is used to cooperate and be connected to the cam groove 21; the top of the follower bearing seat 321 is provided with a notch slot for connecting to the floating joint 66.

[0058] The following is a detailed introduction to the detailed connection mode and use method of each component included in the device provided by the present invention.

[0059] The device includes a stem 1, a lower cam 2, a guide unit 3, a module mounting seat 4, a medicine pool unit 5, a medicine charging module 6, a driving gear 7, a connecting tube 8, a medicine supply tube 9, a spoke plate 10, etc. In actual use, mounting plates for fixing the stem 1 can also be arranged above and below the stem 1.

[0060] The guide unit 3 includes a guide frame 31 , a cam slider 32 , a guide shaft 311 and the like.

[0061] The charging module 6 may include a base 61 , a lower punch 62 , a metering plate 63 , an adjusting plate 610 , a funnel 64 , a cover plate 65 , a floating joint 66 and the like.

[0062] The cam slider 32 may include a follower bearing seat 321 , a follower shaft 322 , a cam follower 323 , a linear bearing 324 , and the like.

[0063] The connection relationship between the various components is: the lower cam 2 is installed on the core column 1, the bearings contained in each rotatable component are strung on the core column 1 in sequence, the module mounting seat 4 is connected to the core column 1 through the bearings, the medicine pool unit 5 is connected to the upper end of the module mounting seat 4, and the gear is connected to the medicine pool unit 5 through the connecting tube 8; a number of charging modules 6 are connected to the corresponding positions of the module mounting seat 4, and are evenly distributed in a ring with the core column 1 as the center, and the upper end is in contact with the medicine pool so that the respective medicine supply channel 67 of each charging module 6 is connected to the inside of the medicine pool.

[0064] The guide frame 31 is connected to the module mounting seat 4 through the spoke plate 10. The gear, the connecting tube 8, the medicine cell unit 5, the module mounting seat 4, the spoke plate 10, the guide frame 31, and the medicine charging module 6 are connected as a whole and can rotate synchronously around the core column 1. The guide shaft 311 in the guide frame 31 passes through the linear bearing 324 in the cam slider 32, so that the cam slider 32 can slide along the axial direction of the core column 1 and can rotate synchronously with the guide frame 31. The floating joint 66 in each medicine charging module 6 is respectively connected to the notch card slot of the cam slider 32, so that the lower punch 62 in the medicine charging module 6 can move up and down with the cam slider 32; the cam follower 323 in the cam slider 32 is installed in the cam groove 21 of the lower cam 2, and moves along the cam curve of the cam groove 21 as the cam slider 32 rotates; the medicine supply tube 9 is fixed to the mounting plate connected to the core column 1.

[0065] In the charging module 6, the lower punch 62 is connected to the lower part of the base 61 through the linear bearing 324, and the metering plate 63, the adjusting plate 610, and the funnel 64 are pressed on the upper part of the base 61 by the metering plate cover 65, and can slide along the slot. The position relationship between the metering plate 63 and the adjusting plate 610 can be adjusted by screws, and they are fixed to each other during operation. The cavity surrounded by the metering plate 63, the adjusting plate 610, the base 61 and the cover 65 is the metering chamber 69.

[0066] In the cam slider 32 , the cam follower 323 is mounted on the follower bearing seat 321 via the follower shaft 322 , and the linear bearing 324 is mounted on the follower bearing seat 321 and fixed by a clamping ring.

[0067] The working process of the charge charging device provided in the embodiment of the present invention is:

[0068] Under normal working conditions, all rotatable parts of the rotor structure are driven to rotate synchronously by an external driver, and the propellant is input from the supply pipe 9 and filled into the medicine pool unit 5. When the medicine surface is submerged in the mouth of the supply pipe 9, the mouth is sealed to maintain the height of the medicine surface. The propellant enters the medicine supply channel 67 of each charging module 6 through the hole at the bottom of the medicine pool unit 5.

[0069] At the loading position, the cam slider 32 is at the low point height of the cam groove 21, and the cartridge case 11 to be loaded is fed in tangentially along the circumference by other rotors of the production line. As the rotor structure rotates, the cam slider 32 rises along the cam groove 21, pushing the connected lower punch 62 to rise, and the cartridge case 11 to be loaded on the lower punch 62 rises accordingly, and the cartridge case 11 to be loaded can contact the funnel 64 and push the funnel 64 and the metering plate 63 to rise, so that the metering chamber 69 surrounded by the metering plate 63, the adjustment plate 610 and the base 61 can be connected and conducted with the feed channel filled with propellant in the base 61, and the propellant can flow into and fill the metering chamber 69.

[0070] Then, as the rotation proceeds, the cam slider 32 descends along the cam groove 21 to the charging height, and the metering plate 63, the adjusting plate 610 and the funnel 64 will move downward synchronously with the lower punch 62 under the action of gravity, and finally the metering chamber 69 is isolated from the upper feeding channel, and then connected to the lower channel 68, and the propellant in the cavity of the metering chamber 69 flows into the shell 11 to be charged through the lower channel 68 and the funnel 64. The cam groove 21 of the cam may have a wavy structure, so that the cam slider 32 can vibrate up and down, and assist the medicine in the funnel 64 to fall. Then the cam slider 32 descends to the low point height along the cam groove 21, and the shell that has completed the charge is transferred to the next rotor device along the circumferential tangent.

[0071] When it is necessary to charge cartridge cases of different specifications, a production change operation can be performed, which specifically includes removing the charging module 6 at the production change position (the high point of the cam groove 21) and replacing it with a charging module 6 adapted to another product, so that the production change can be completed quickly.

[0072] When it is necessary to adjust the charge amount in the metering chamber 69, the positional relationship between the metering plate 63 and the adjusting plate 610 can be adjusted. Since the contact parts between the metering plate 63 and the adjusting plate 610 move relative to each other, the size of the metering chamber 69 can be changed, thereby realizing the function of adjusting the charge amount.

[0073] It can be seen that the device provided by the present invention has a charge module 6 that can be replaced as a whole, and has a metering chamber 69 with an adjustable volume, and the debugging information (volume of the metering chamber 69) can be maintained during replacement. When a shell enters the charge module 6, the funnel 64 will be lifted up and the metering chamber 69 will be connected to the propellant feeding channel; when there is no shell, the metering plate 63 part does not move, and the propellant will not enter the metering chamber 69 and the lower channel 68, realizing the logical function.

[0074] It is understandable that the connection mode of the rotating system provided by the present invention is not limited to the core column-bearing-mold frame, and can also adopt the form of shaft seat-bearing-core shaft. At the same time, the installation position of the driving gear 7 is not limited to the upper part of the device.

[0075] In summary, the continuous gun bullet constant volume charging device provided by the present invention realizes the automatic charging process of the cartridge case. Through modular design, the design of the split structure of the module mounting seat and the charging module can realize the rapid production change of different types of products, facilitate the rapid disassembly, maintenance, transportation and storage of the equipment, and improve the flexibility of the production line. The lower punch is used to drive the cartridge case to lift up to start the charging. The propellant can only flow out when there is a cartridge case on the lower punch. This method can make a judgment on whether there is a cartridge case input, avoid the propellant from being scattered or shutting down when the previous feeding mechanism fails, improve the efficiency of the equipment, and greatly improve the safety of the equipment operation.

[0076] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
