Description

Technical Field

[0001] The invention relates to the technical field of heating plate pressurizing tooling, and in particular to a 10N thruster solenoid valve heating plate pressurizing tooling and a method. Background Art

[0002] The thermal control implementation work of the 10N thruster in the general assembly stage is mainly to paste the heating plate on the surface of the solenoid valve of the 10N thruster. The 10N thruster includes two cylindrical solenoid valves arranged in parallel, namely the oxygen solenoid valve and the fuel solenoid valve. The outer periphery of the two solenoid valves is only 5mm apart at the closest point, and the outer periphery of the two solenoid valves needs to be pasted with heating plates. The thickness of the heating plates is about 0.3mm. The heating plate of the oxygen solenoid valve is located on the side close to the fuel solenoid valve, and the heating plate of the fuel solenoid valve is located on the side close to the oxygen solenoid valve. After pasting the heating plates, the pressurizing tooling needs to be used to pressurize the pasting part of the heating plates, and the pressurizing tooling is removed after curing for 36 hours.

[0003] The existing pressurized tooling mainly has the following problems:

[0004] (1) The distance between the two solenoid valves of the 10N thruster is only 5mm, which makes it impossible to pressurize the heating plates of the two solenoid valves at the same time;

[0005] (2) There is a boss structure on the outer periphery of the two solenoid valves. The thickness of the boss is greater than the thickness of the heating plate, and the two sides of the heating plate are not easily compressed.

[0006] Therefore, how to achieve simultaneous pressurization of the two solenoid valve heating plates and uniform pressure on both sides of the heating plates has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0007] The invention provides a 10N thruster solenoid valve heating plate pressurizing tool and method, which are used to solve the problem of how to pressurize two solenoid valve heating plates at the same time and how to pressurize both sides of the heating plates evenly.

[0008] On the one hand, the present invention provides a 10N thruster solenoid valve heating plate pressurizing tooling, the 10N thruster solenoid valve comprises an oxygen solenoid valve and a fuel solenoid valve arranged in parallel, and both solenoid valves are provided with bosses in their circumferential directions, and the pressurizing tooling comprises:

[0009] A first pressurizing member capable of pressurizing the heating plate of the oxygen solenoid valve;

[0010] A second pressurizing member is capable of pressurizing the heating plate of the combustion solenoid valve;

[0011] The sum of the thicknesses of the middle portion of the first pressurizing member and the middle portion of the second pressurizing member is less than the distance between the two solenoid valves;

[0012] The first pressurizing member and the second pressurizing member have the same structure, and the first pressurizing member includes:

[0013] The pressurizing body has wedge-shaped structures at both ends, and the pressurizing body can cover the outer periphery of the heating plate of the oxygen solenoid valve;

[0014] A pressurized binding belt capable of pressurizing the pressurized subject;

[0015] The pressurized binding belt is a nylon belt, which is installed on both sides of the pressurized body. The end of the nylon belt is connected to the wire take-up device, and a limit block is provided on the nylon belt.

[0016] In some of the embodiments, the number of the nylon belts is an even number and is symmetrically distributed on both sides of the pressurizing body.

[0017] In some of the embodiments, a guide ring is provided on the pressurizing body, and the nylon belt is installed on the pressurizing body through the guide ring.

[0018] In some of the embodiments, the thickness of the end of the wedge-shaped structure is greater than the thickness of the boss.

[0019] In some embodiments, an arc-shaped through groove is provided on the upper portion of the pressurizing body, the thickness at both ends of the pressurizing body is greater than the thickness in the middle portion, and the nylon belt is located on a side of the pressurizing body away from the arc-shaped through groove.

[0020] In some of the embodiments, the material of the pressurized body is TPU.

[0021] In some of the embodiments, the pressurized body is integrally formed using a 3D printing process.

[0022] In some of the embodiments, the thickness of the middle portion of the pressurized body is 1 mm.

[0023] On the other hand, the present application also provides a 10N thruster solenoid valve heating plate pressurizing method, using a 10N thruster solenoid valve heating plate pressurizing tooling.

[0024] In some embodiments, the pressurizing method comprises:

[0025] The first pressurizing member is placed on the outer periphery of the heating plate of the oxygen solenoid valve, and the wire take-up device is rotated until the wire take-up device abuts against the limit block;

[0026] The second pressurizing member is used to pressurize the heating plate of the combustion solenoid valve, and the pressurizing method is the same as the pressurizing method of the first pressurizing member.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. By opening an arc-shaped through groove on the upper part of the pressurizing body, the two ends of the pressurizing body are thick and the middle is thin. On the one hand, the thickness of the middle part of the pressurizing body is 1mm, and the thickness of the heating plate is 0.3mm, that is, the sum of the middle thickness of the two heating plates, the first heating element and the second heating element is 2.6mm, which is less than the distance of 5mm between the two solenoid valves, so that the two heating plates can be heated at the same time; on the other hand, the arc-shaped side of the pressurizing body is fitted with the outer periphery of the heating plate, and then the pressurizing binding belt is used for pressurization. The arc-shaped and the heating plate are tightly fitted, so that the surface of the heating plate can be uniformly stressed;

[0029] 2. Both ends of the pressurizing body are designed as wedge-shaped structures, and the thickness of the end of the wedge-shaped structure is greater than the thickness of the boss. The pressurizing strap is used to apply pressure to the pressurizing body. On the one hand, the wedge-shaped structure can avoid the boss, making it easier to apply pressure to the heating plate; on the other hand, the wedge-shaped structure can achieve uniform force on both sides of the heating plate;

[0030] 3. The pressurized body is integrally formed by 3D printing, and its thickness distribution is continuous and uniform, which can fit closely with the heating plate, and can achieve uniform force on the surface of the heating plate;

[0031] 4. The nylon belt has no elasticity. After each use, the pressurized body made of TPU material can be restored to its initial length. That is to say, before each test, the length of the pressurized body and the nylon belt is constant. The take-up device is rotated until the limit block is against the take-up device. At this time, the distance between the limit block and the end of the pressurized body is constant, that is, the length of the nylon belt between the limit block and the pressurized body is constant. That is to say, each time the pressurization test is performed, the stretching length of the pressurized body remains consistent, thereby achieving a constant pressure on the heating plate. The same pressure is applied to the heating plate in each operation, ensuring that the pressurized curing effect of each heating plate is the same. When the two heating plates of the oxygen solenoid valve and the combustion solenoid valve are pressurized at the same time, it can ensure that the two heating plates are subjected to the same pressure, and that the heating plates of different batches are subjected to the same pressure, thereby ensuring that the curing effect of different batches of heating plates is the same, thereby improving the stability of the product.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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.

[0039] As described in the background technology, it is not possible to pressurize two heating plates at the same time using traditional pressurizing tools, which is inefficient, and the two sides of the heating plate are unevenly stressed and cannot be firmly attached to the surface of the solenoid valve. Therefore, it has become a technical problem that technicians in this field need to solve urgently to achieve simultaneous pressurization of two solenoid valve heating plates and uniform pressure on both sides of the heating plate.

[0040] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a 10N thruster solenoid valve heating plate pressurizing tooling, the 10N thruster solenoid valve comprises an oxygen solenoid valve 1 and a fuel solenoid valve 2 arranged in parallel, and both solenoid valves are provided with bosses in their circumferences, the pressurizing tooling comprises: a first pressurizing member 4 and a second pressurizing member 5, the first pressurizing member 4 is sleeved on the outer periphery of the heating plate 3 of the oxygen solenoid valve 1, and then the first pressurizing member 4 is tightened, thereby realizing pressurized curing of the heating plate 3 of the oxygen solenoid valve 1; the second pressurizing member 5 is sleeved on the outer periphery of the heating plate 3 of the fuel solenoid valve 2, and then the second pressurizing member 5 is tightened, thereby realizing pressurized curing of the heating plate 3 of the fuel solenoid valve 2.

[0041] Compared with the pressurized tooling of the prior art, the heating plate 3 of one solenoid valve is pressurized and cured for 36 hours, and then the pressurized tooling is removed and installed on another solenoid valve, and the heating plate 3 of the other solenoid valve is pressurized and cured for another 36 hours, which has low production efficiency and wastes working hours. The present application sets the sum of the sizes of the middle part of the first pressurized member 4 and the middle part of the second pressurized member 5 to be smaller than the distance between the two solenoid valves, so that the middle parts of the first pressurized member 4 and the second pressurized member 5 can be inserted between the two solenoid valves, thereby achieving simultaneous pressurization and curing of the heating plates 3 of the two solenoid valves, thereby improving production and processing efficiency.

[0042] The first pressurizing member 4 and the second pressurizing member 5 have the same structure. The first pressurizing member 4 includes: a pressurizing body 6 and a pressurizing binding belt 7. Both ends of the pressurizing body 6 are wedge-shaped structures 61. The length of the pressurizing body 6 is greater than or equal to the length of the heating plate 3, so that the pressurizing body 6 can completely cover the outer periphery of the heating plate 3 of the oxygen solenoid valve 1. The pressurizing body 6 is then pressurized by the pressurizing binding belt 7, and the pressurizing body 6 transfers the pressure to the heating plate 3, thereby realizing pressurized curing of the heating plate 3.

[0043] Compared with the pressurizing tooling of the prior art, the heating plate 3 is directly pressurized. The thickness of the boss 8 is greater than the thickness of the heating plate 3, and the two sides of the heating plate 3 cannot be pressurized, resulting in poor curing effect on the two sides of the heating plate 3, which is easy to crack, affecting the heating effect of the heating plate 3 on the solenoid valve. The thickness of the end of the wedge-shaped structure 61 of the present application is greater than the thickness of the boss 8, and the pressurizing binding belt 7 presses the pressurizing body 6. The wedge-shaped structure 61 presses the side of the heating plate 3 inward. On the one hand, the wedge-shaped structure can avoid the boss, which is convenient for pressurizing the heating plate; on the other hand, the wedge-shaped structure can achieve uniform force on both sides of the heating plate, as well as pressurized fixation of both sides of the heating plate.

[0044] like Figure 5 As shown, the pressurized binding belt 7 is exemplarily a nylon belt 9. The 10N thruster solenoid valve heating plate pressurized tooling of the present application includes a pressurized body 6 and nylon belts 9 located at both ends of the pressurized body 6. The nylon belt 9 is located on the side of the pressurized body 6 away from the arc-shaped through groove 62. The end of the nylon belt 9 is connected to the take-up device 11. The nylon belt 9 is provided with a limit block 10. The nylon belt 9 is fixedly connected to the pressurized body 6. The pressurized body 6 is provided with a guide ring. The nylon belt 9 is installed on the pressurized body 6 through the guide ring. The nylon belt 9 can be tied to the guide ring. The number of nylon belts 9 can be 2, 4, or 6, which are symmetrically and evenly distributed on both sides of the pressurized body 6.

[0045] During specific use, the 10N thruster solenoid valve heating plate pressurizing tooling is sleeved on the outer periphery of the heating plate 3 of the solenoid valve, and the wire take-up 10 is rotated. The nylon belts 9 on both sides of the pressurizing body 6 are contracted synchronously, and the pressurizing body 6 made of TPU material is stretched by force until the limit block 10 abuts against the wire take-up 11, and the rotation of the wire take-up 11 is stopped, thereby achieving pressure on the heating plate 3. The operation is simple and convenient, and can be completed by one person.

[0046] The pressurizing body 6 is made of TPU material. On the one hand, the rotating wire take-up device 11 stretches the pressurizing body 6. Based on the tensile strength of TPU, which can be as high as 70MPa, and the elongation at break, which can be as high as 1000%, TPU can be significantly elongated without breaking when subjected to tensile force. On the other hand, the high elasticity of TPU enables it to return to its original shape after being stretched by force, and no permanent deformation will occur. After each use, the pressurizing body 6 made of TPU material can be restored to its original length.

[0047] It is worth noting that the nylon belt 9 has no elasticity. After each use, the pressurized body 6 made of TPU material can be restored to its initial length. That is to say, before each test, the length of the pressurized body 6 and the nylon belt 9 is constant, and the wire take-up device 11 is rotated until the limit block 10 is against the wire take-up device 11. At this time, the distance between the limit block 10 and the end of the pressurized body 6 is constant, that is, the length of the nylon belt 9 between the limit block 10 and the pressurized body 6 is constant. That is to say, each time the pressurization test is performed, the stretching length of the pressurized body 6 remains consistent, thereby achieving a constant pressure applied to the heating plate 3, ensuring that the effect of pressurized curing of the heating plate 3 is the same each time, and when the two heating plates 3 of the oxygen solenoid valve 1 and the fuel solenoid valve 2 are pressurized at the same time, it can be ensured that the two heating plates 3 are subjected to the same pressure, and the heating plates 3 of different batches are subjected to the same pressure, thereby ensuring that the curing effect of different batches of heating plates 3 is the same, thereby improving the stability of the product.

[0048] Preferably, an arc-shaped through groove 62 is provided on the upper part of the pressurizing body 6, and the thickness at both ends of the pressurizing body 6 is greater than the thickness in the middle, that is, the thickness of the pressurizing body 6 increases continuously in the direction from the middle to the two ends, and the two ends form a wedge-shaped structure 61, which is thin in the middle and convenient for insertion between the two solenoid valves. The present application designs an arc-shaped through groove 62. On the one hand, the pressurizing body 6 is bent and wrapped around the outer periphery of the heating plate 3. The arc-shaped through groove 62 can fit tightly with the outer periphery of the heating plate 3, and can evenly apply pressure to the outer periphery of the heating plate 3, thereby achieving uniform force on the heating plate 3 and improving the pressurized curing effect of the heating plate 3; on the other hand, the arc-shaped through groove 62 can realize a structure in which the pressurizing body 6 is thick at both ends and thin in the middle, which is convenient for inserting the middle part of the pressurizing body 6 between the two solenoid valves, and for forming a wedge-shaped structure 61 at both ends of the pressurizing body 6, so as to achieve uniform force on both sides of the heating plate 3.

[0049] Preferably, the material of the pressurized body 6 is TPU, that is, thermoplastic polyurethane elastomer, which is integrally formed by 3D printing process. The present application utilizes the excellent elasticity of TPU material to withstand repeated stretching and compression without permanent deformation. When the heating plate 3 is pressurized and cured, the pressurized body 6 is bent into an arc shape. Under the action of the pressurized binding belt 7, the pressurized body 6 can be consistent with the outer peripheral bending arc of the pressurized plate 3 and fit closely; after the pressurization work is completed, the external force of the pressurized binding belt 7 is released, and the pressurized body 6 is restored to the original strip shape, and can be repeatedly worked for many times. The pressurized body 6 will not be permanently deformed. The pressurized body 6 made of TPU material can be deformed and rebounded according to the use conditions, which is easy to operate and has a long service life. The pressurized body 6 integrally formed by 3D printing process has a continuous and uniform thickness distribution, which can not only reasonably avoid the solenoid valve surface boss 8, but also fit closely with the cylindrical surface heating plate 3, so as to facilitate the uniform force of the heating plate 3.

[0050] Preferably, the thickness of the middle part of the pressurizing body 6 is 1 mm, which is convenient for passing through the narrow gap between the two solenoid valves. When the thickness of the pressurizing body 6 made of TPU material is 1 mm, it can still maintain excellent elasticity and toughness, and will not break or have defects such as breakage under tension and pressure. When using 3D printing technology to process a tiny size of 1 mm, the good performance of the heating body 6 can still be maintained, and no defects will occur that affect the performance of the pressurizing body 6.

[0051] In another embodiment, the pressurized binding belt 7 includes: an elastic rubber skin 71 and a nylon buckle 72, the elastic rubber skin 71 is a rectangular structure, and the nylon buckle 72 is located at both ends of the elastic rubber skin 71. When used, the elastic rubber skin 71 is wrapped around the outer periphery of the pressurized body 6, the two ends of the elastic rubber skin 71 are tightened, and the nylon buckles 72 at both ends of the elastic rubber skin 71 are bonded.

[0052] The elastic rubber skin 71 is designed to be a rectangular structure, and its size is larger than the pressurizing body 6, and it can completely wrap the outer periphery of the pressurizing body 6. By uniformly applying force to the outer periphery of the pressurizing body 6, the pressurizing body 6 transfers the pressure to the heating plate 3, thereby achieving uniform force on the heating plate 3.

[0053] The design of the nylon buckle 72, on the one hand, only requires bonding to achieve a fixed connection between the two ends of the elastic rubber skin 71, which is simple and convenient to operate; on the other hand, the nylon buckle 72 has a rough surface and high friction, which can prevent the elastic rubber skin 71 from slipping when force is applied to both ends of the elastic rubber skin 71 and tightened at the same time, making it easier to apply force.

[0054] Preferably, the thickness of the elastic rubber skin 71 is 0.5 mm. The design of the elastic rubber skin can still maintain good elasticity when the thickness of the binding belt body 71 is 0.5 mm, and will not have a break defect that affects the use, and has a certain elasticity, which is convenient for applying pressure to the pressurizing body 6 and the heating plate 3 by stretching the elastic rubber skin.

[0055] It should be noted that, in the present application, an arc-shaped through groove is provided on the upper part of the pressurizing body 6 so that the two ends of the pressurizing body 6 are thick and the middle is thin. On the one hand, the thickness of the middle part of the pressurizing body 6 is 1 mm, the thickness of the elastic rubber skin is 0.5 mm, and the thickness of the heating plate is 0.3 mm, that is, the sum of the intermediate thicknesses of the two heating plates, the first heating element and the second heating element is 3.6 mm, which is less than the distance of 5 mm between the two solenoid valves, and can realize simultaneous heating of the two heating plates 3; on the other hand, the arc-shaped side of the pressurizing body 6 is fitted with the outer periphery of the heating plate 3, and then pressurized with the elastic rubber skin, so that the arc shape is tightly fitted with the heating plate 3, so that the surface of the heating plate 3 can be uniformly stressed.

[0056] It should be noted that the pressurizing body 6 and the pressurizing binding belt 7 simultaneously achieve the fixation and pressurization of the heating plate 3 , optimize the operation steps, and avoid the risk of the heating plate 3 slipping.

[0057] In order to facilitate the simultaneous installation of the pressurizing body 6 and the pressurizing binding belt 7, guide rings are provided on the two ends of the pressurizing body 6 on one side away from the arc-shaped through groove 62. The two ends of the pressurizing binding belt 7 pass through the guide rings at the two ends of the pressurizing body 6 respectively, and then the pressurizing body 6 and the pressurizing binding belt 7 are simultaneously covered on the outer periphery of the heating plate 3, thereby improving the installation efficiency of the pressurizing tooling and making the operation simple and convenient.

[0058] The present invention also provides a 10N thruster solenoid valve heating plate pressurizing method, which uses a 10N thruster solenoid valve heating plate pressurizing tool.

[0059] Preferably, the method comprises the following steps:

[0060] The first pressurizing member 4 is wrapped around the heating plate 3 of the oxygen solenoid valve 1 , and the pressurizing band 7 is used to pressurize the heating plate 3 ; the second pressurizing member 5 is used to pressurize the heating plate 3 of the fuel solenoid valve 2 , and the pressurizing method is the same as that of the first pressurizing member 4 .

[0061] Specifically, the installation of the first pressurizing member 4 is taken as an example for detailed description: the pressurizing body 6 and the elastic rubber skin 71 are inserted into the gap between the two solenoid valves from the top, the pressurizing body 6 is bent to cover the heating plate 3, and one side of the arc-shaped through groove 62 is fitted with the heating plate 3; then the elastic rubber skin 71 is covered with the pressurizing body 6, and the two ends of the elastic rubber skin 71 are tightened, and then the nylon buckles at the two ends are connected and fixed, thereby realizing the pressurized curing of the heating plate 3 of the oxygen solenoid valve 1.
