Description

Technical Field

[0001] This utility model relates to the field of installation fixtures, and in particular to an installation fixture for assembling the left-side missile slide of a helicopter. Background Technology

[0002] When assembling the left bomb inlet slide of a certain type of helicopter, a mandrel is first inserted into the left bomb inlet slide, and then a wire compression spring is sleeved on the outside of the mandrel. The lower ends of the wire compression spring and the mandrel are located at the bottom of the left bomb inlet slide. Since the length of the wire compression spring is much longer than the length of the mandrel, the wire compression spring needs to be compressed during assembly. The spring needs to be compressed to a position lower than the mounting pin hole on the mandrel so that the cylindrical pin can be inserted into the mounting pin hole, thereby preventing the compressed wire compression spring from opening after the compression force is removed. In other words, the spring needs to be positioned.

[0003] However, the wire diameter of this wire compression spring is 3.8mm, and the outer diameter of the spring is 21mm. Furthermore, since the length of the wire compression spring is much longer than the mandrel, it is difficult for operators to compress the wire compression spring to the designated position and maintain its compressed state during assembly. The required pressure is relatively large. Manually compressing the spring to the designated position is uncontrollable and cannot stabilize the compression state of the spring. It may even damage the mandrel and the wire compression spring. Moreover, inserting the cylindrical pin for positioning under stable compression is impossible for a single person to complete.

[0004] In addition, because the length of the wire compression spring is much longer than that of the mandrel, the spring will deflect during the process of compressing the wire compression spring to a position lower than the mandrel mounting pin hole, resulting in inaccurate positioning and unsuccessful assembly.

[0005] Therefore, based on feedback from existing technologies regarding the shortcomings of assembling left-hand missile slides, the inventors designed an installation fixture for assembling left-hand missile slides on helicopters to overcome the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an installation clamp for assembling the left inlet slide of a helicopter that is accurate in positioning, controllable in force application, and easy to install and disassemble.

[0007] The objective of this utility model is achieved through the following technical solution: a mounting clamp for assembling a left-hand advance missile slide of a helicopter. The left-hand advance missile slide assembly includes a mandrel, a wire compression spring, and a left-hand advance missile slide. The mandrel is fitted with a wire compression spring, and both the mandrel and the wire compression spring are inserted into the left-hand advance missile slide to its bottom. A mounting pin hole is opened at the top of the mandrel. After the wire compression spring is compressed, a cylindrical pin is inserted into the mounting pin hole for positioning. The invention is characterized by including a support cylinder, a sleeve, a guide cylinder, and a clamping part.

[0008] The support cylinder is open at the top and sealed at the bottom. The left-in spring slide cylinder assembly is inserted into the bottom of the cylinder through the top port of the support cylinder, and the top end face of the support cylinder is connected to the sleeve screw.

[0009] The guide cylinder has a long groove, and the guide cylinder is inserted into the support cylinder and sleeved outside the steel wire compression spring;

[0010] The sleeve has a long groove, the bottom end of the sleeve is connected to the support cylinder, and the other end is the top end that mates with the clamping part.

[0011] The clamping part is provided with a screw that is connected to the sleeve through a matching nut, and the screw extends into the sleeve. The end of the screw is slotted and inserted into the inner hole of the guide tube.

[0012] During installation, insert the left advance slide into the support cylinder, then insert the mandrel and the steel wire compression spring sleeved on the mandrel into the left advance slide. The guide cylinder is sleeved on the steel wire compression spring. Connect one end of the sleeve to the support cylinder and the other end to the clamping part. Insert the screw end of the clamping part into the guide cylinder and abut against the steel wire compression spring.

[0013] During operation, first observe and adjust the slotted position of the screw end so that the slot is aligned with the mounting pin hole of the spindle. Rotate the nut to make the screw move downward. The screw end will press the steel wire compression spring down below the mounting pin hole. Then insert the cylindrical pin into the mounting pin hole to complete the assembly.

[0014] As a preferred technical solution of this application, a limiting block is provided on the top end face of the sleeve, the limiting block limits the nut so that the nut can only rotate and cannot have axial displacement with the sleeve; an elongated hole is provided on the top end face of the sleeve to limit the screw, so that the screw cannot rotate and can only move up and down.

[0015] As a preferred technical solution of this application, the support cylinder has a long groove on its body, so that after the left advance slide cylinder is inserted into the support cylinder, it can be observed through the long groove whether it is in place; the support cylinder and the sleeve are connected by detachable screws, so that after the left advance slide cylinder assembly is completed, the screws are removed to remove the support cylinder, thereby taking out the left advance slide cylinder assembly.

[0016] As a preferred technical solution of this application, the bottom end of the guide cylinder abuts against the bottom of the sleeve, and the length of the guide cylinder is the same as the length of the steel wire compression spring, which can wrap the steel wire compression spring inside, and the guide cylinder can prevent the steel wire compression spring from deflecting during the compression process.

[0017] As a preferred technical solution of this application, the clamping part includes a nut and a screw. The lower part of the nut is limited by a limiting block on the sleeve, and a rotating rod is provided on the upper part of the nut. When the rotating rod is rotated, the nut rotates, thereby enabling the screw to move up and down.

[0018] As a preferred technical solution of this application, the lower end of the screw is a round rod with a groove at the end, and the upper end of the screw is a threaded rod with external threads. Its lower end passes through the nut and extends into the sleeve. The external thread at the upper end matches the internal thread on the inner wall of the nut. When the rotating rod is rotated, the nut rotates, and the internal thread of the nut rotates, thereby driving the threaded rod to move up and down.

[0019] This utility model has the following advantages:

[0020] (1) Precise positioning;

[0021] Currently, when installing the left missile slide assembly of a certain type of helicopter, since there are no special tools available on the market for its assembly, manual operation is usually used. However, because the total length of the steel wire compression spring that needs to be compressed for positioning is much longer than the length of the mandrel, it is easy for the steel wire compression spring to be deflected and the positioning to be inaccurate when manually compressing the steel wire compression spring until the mandrel is lower than the mounting pin hole, thus leading to unsuccessful assembly.

[0022] This solution uses a support cylinder to insert and fix the left-infeed slide cylinder assembly. A sleeve is used to fix the clamping mechanism, i.e., the clamping part. Then, a guide cylinder is installed outside the steel wire compression spring. The length of the guide cylinder is the same as the length of the steel wire compression spring. When the screw end of the clamping part extends into the sleeve, it is positioned in the inner hole of the guide cylinder and abuts against the steel wire compression spring. The design of the guide cylinder structure ensures that the steel wire compression spring can only be compressed within the guide cylinder during the compression process of the screw, thus preventing the steel wire compression spring from deflecting during the compression process and ensuring accurate positioning.

[0023] (2) The force can be controlled, which can stabilize the state of spring compression;

[0024] Currently, because the wire diameter of the steel wire compression spring is 3.8mm, its outer diameter is 21mm, and the length of the spring is very long, the pressure required for the operator to manually compress the steel wire compression spring to the position of the mounting pin hole on the mandrel is relatively large, and it is necessary to stabilize the spring below the compression state of the mounting pin hole in order to insert the cylindrical pin for positioning. The whole process is quite difficult.

[0025] This design incorporates a clamping section. Through the threaded engagement of the nut and screw, the rotational torque is converted into the pressure of a compression spring by twisting the threaded structure. Rotating the nut causes the screw to move into the guide cylinder, compressing the steel wire spring. Throughout the process, it can be observed that the amount of spring compression is constant by rotating the nut, thus controlling the applied clamping force. Furthermore, the steel wire compression spring does not rebound, maintaining a stable compression state below the mounting pin hole position, thereby completing the assembly.

[0026] (3) The structure is simple and easy to install and disassemble;

[0027] The support cylinder and sleeve in this design are connected by detachable screws, making it easy to install the left-infeed slide cylinder assembly into the fixture. After assembly, only the locking screws between the support cylinder and sleeve need to be removed to take out the assembled left-infeed slide cylinder assembly. This design uses the support cylinder, guide cylinder, and sleeve to position the assembly and limit the clamping part, and uses the clamping part to compress the wire compression spring. The overall structure is relatively simple, easy to operate, and does not easily damage the spindle and wire compression spring. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0037] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] It should be noted that the helicopter left-side missile launcher assembly includes a wire compression spring 1, a spindle 2, and a left-side missile launcher 3. The spindle 2 is fitted with a wire compression spring 1, the length of which is much longer than the length of the spindle 2. The bottom ends of both the spindle 2 and the wire compression spring 1 are inserted into the bottom of the left-side missile launcher 3. A mounting pin hole 4 is opened at the top of the spindle 2. When assembling the left-side missile launcher 3, the wire compression spring 1, which is much longer than the spindle 2, needs to be compressed to a position below the mounting pin hole 4. Then, the wire compression spring 1 is positioned and assembled by inserting a cylindrical pin into the mounting pin hole 4.

[0040] In the existing technology, it is very difficult to compress the wire compression spring 1 into the mounting pin hole 4 by manual operation by the staff. Moreover, it is impossible for a single person to stabilize the wire compression spring 1 in the mounting pin hole 4 and then insert the cylindrical pin for positioning. The assembly process is very time-consuming and laborious, and it is easy to damage the mandrel 2 and the wire compression spring 1. In the current market, there is no auxiliary assembly fixture for assembling the wire compression spring 1 and mandrel 2 of the left advance slide cylinder 3.

[0041] Therefore, based on the above issues, please refer to Figures 1-7 This utility model proposes an installation fixture for assembling the left-side missile slide of a helicopter to solve the problem.

[0042] (Example 1)

[0043] See Figures 1 to 7 The mounting fixture for assembling the left-side missile slide of a helicopter proposed in this embodiment includes a support cylinder 5, a sleeve 6, a guide cylinder 7, and a clamping part;

[0044] Among them, see Figure 3 and Figure 4 The support cylinder 5 has an opening at the top, allowing the left-feeding slide cylinder 3 to be inserted into the bottom of the cylinder through the top; the bottom end of the support cylinder 5 is sealed, and a threaded hole is provided on the top end face, which is connected to the sleeve 6 by screws;

[0045] Among them, see Figure 4 The guide cylinder 7 has a long groove, and the guide cylinder 7 is inserted into the support cylinder 5 and sleeved on the steel wire compression spring 1 of the left spring slide cylinder 3 assembly.

[0046] Among them, see Figure 4 The sleeve 6 has a long groove. One end of the sleeve 6 is screwed to the support sleeve 5, and the other end is connected to the clamping part.

[0047] Among them, see Figure 5 The clamping part includes a nut 9 and a screw 8. The screw 8 is connected to the sleeve 6 through the nut 9. At the same time, the nut 9 is limited by the limiting block set on the end face of the sleeve 6, so that the nut 9 can only rotate and cannot have axial displacement with the sleeve 6. The screw 8 extends into the sleeve 6, and the end of the extension is slotted and inserted into the inner hole of the guide cylinder 7, abutting against the steel wire compression spring 1. At the same time, an elongated hole is opened on the end face of the sleeve 6 to limit the screw 8, so that the screw 8 cannot rotate and can only move up and down.

[0048] When placing the left advance slide cylinder 3 into the installation fixture, first insert the left advance slide cylinder 3 into the support cylinder 5, then insert the mandrel 2 into the bottom of the left advance slide cylinder 3, and at the same time, the wire compression spring 1 is sleeved on the outside of the mandrel 2. Both the mandrel 2 and the wire compression spring 1 are in contact with the bottom of the left advance slide cylinder 3. Then, the guide cylinder 7 is sleeved on the outside of the wire compression spring 1, and the bottom end of the guide cylinder 7 also abuts against the bottom of the left advance slide cylinder 3. Connect the sleeve 6 from one end of the clamping part with screws, and then insert one end of the clamping part into the inner hole of the guide cylinder 7 through the sleeve 6, abutting against the wire compression spring 1. The bottom end of the sleeve 6 is connected to the support cylinder 5 with screws, and a limiting block is set on the other end face. Insert the nut 9 into the clamping part until it is engaged with the limiting block, so that the nut 9 can only rotate and cannot have axial displacement with the sleeve 6.

[0049] When the mounting fixture is in operation, after the left spring slide cylinder 3 is inserted, the clamping part is inserted into the guide cylinder 7 and presses against the upper end of the wire compression spring 1. Since both the guide cylinder 7 and the sleeve 6 have grooves, the position of the groove at the tail of the clamping part can be adjusted by observation to make the groove opening aligned with the mounting pin hole 4 on the mandrel 2. Rotate the nut 9 to make the screw move downward, compressing the wire compression spring 1 to below the mounting pin hole 4 on the mandrel 2, and at this time the mounting pin hole 4 can be seen from the groove opening of the clamping part. Then insert the cylindrical pin through the groove opening into the mounting pin hole 4, thus completing the assembly of the left spring slide cylinder 3. Finally, remove the locking screw between the support cylinder 5 and the sleeve 6, and take out the left spring slide cylinder 3 assembly - that is, the assembly work of the entire assembly is completed.

[0050] This design proposes a dedicated auxiliary installation fixture for assembling the left-side missile launcher assembly of a certain type of helicopter. Currently, there are no dedicated auxiliary assembly tools for assembling the left-side missile launcher assembly 3 of a helicopter. Instead, the steel wire compression spring 1 is manually compressed to a position below the mounting pin hole 4, and then a cylindrical pin is inserted for positioning. This assembly process is time-consuming and labor-intensive, and relying solely on brute force for compression can easily damage the mandrel 2 and the steel wire compression spring 1. This design incorporates a clamping structure that converts the rotational torque of the threaded structure into pressure to compress the steel wire compression spring 1. This allows the screw to stabilize the steel wire compression spring 1 at the mounting pin hole 4 and position it with a cylindrical pin. Compared to conventional assembly methods, the force application method used in this design is ingenious and simple, minimizing the risk of damage to the mandrel 2 and the steel wire compression spring 1. Furthermore, this design includes a support cylinder 5 to fix the left-side missile launcher assembly 3, which cooperates with the sleeve 6 and guide cylinder 7 to ensure that the screw compresses the steel wire compression spring 1 to the designated position and prevents it from rebounding, facilitating subsequent assembly.

[0051] In this embodiment, see Figure 3 and Figure 4 Regarding the design of the support cylinder 5, the support cylinder 5 is cylindrical in shape, with a through hole and a sealed bottom. The support cylinder 5 has four slots on its body to facilitate observation of whether the left advance slide cylinder 3 is in place after it is installed. The open end of the support cylinder 5 is set as a disc surface with two threaded holes, which are connected to one end of the sleeve 6 by screws. When the left advance slide cylinder 3 is installed into the support cylinder 5, the bottom of the left advance slide cylinder 3 rests against the bottom of the support cylinder 5. Then, the mandrel 2 is inserted into the left advance slide cylinder 3, and the steel wire compression spring 1 is sleeved on the outside of the mandrel 2. The bottom ends of the mandrel 2 and the steel wire compression spring 1 are both located at the bottom of the left advance slide cylinder 3 inside the support cylinder 5.

[0052] In this embodiment, see Figure 3 and Figure 4Regarding the design of sleeve 6, sleeve 6 is also cylindrical in shape. The bottom of sleeve 6 is a disc-shaped surface, which matches the open end face of support cylinder 5 and is connected by screws. The bottom of sleeve 6 is provided with a through hole, the diameter of which is the same as the diameter of the through hole in support cylinder 5, so that sleeve 6 can be sleeved on the mandrel 2 and the steel wire compression spring 1 through the through hole. Two hollow grooves are formed in the body of sleeve 6, which form the bottom of the sleeve to connect two long rods. The other end of the two long rods is connected to the top end face of sleeve 6. The two long rods are connected by a... Two rings are connected to each other, dividing the cylinder into two sections. A long hole is also provided on the top cover end face of the sleeve 6 for cooperating with the clamping part, so that after the clamping part is inserted into the sleeve 6 from the top cover, it cannot rotate but can only move up and down. At the same time, two limiting blocks are also provided on the top cover of the sleeve 6. The limiting blocks are inverted L shape and are symmetrically arranged on the top cover. Their lower parts are connected to the top cover and their upper parts are in contact with the nut 9. The upper part of the limiting block is inserted into the nut 9, so that the nut 9 can only rotate and there is no vertical displacement.

[0053] In this embodiment, see Figure 4 Regarding the design of the guide cylinder 7, the guide cylinder 7 is sleeved outside the wire compression spring 1 and can completely enclose the wire compression spring 1 inside. The bottom end of the guide cylinder 7 abuts against the bottom of the sleeve 6. The guide cylinder 7 also has grooves on its body to facilitate observation of the compression state of the wire spring inside. When the clamping part is inserted into the sleeve 6, the end of the screw extending into the sleeve 6 is aligned with the inner hole at the top of the guide cylinder 7 - that is, the end of the clamping part is installed above the wire compression spring 1. When the screw is pressed down, the end of the screw presses the wire compression spring 1 down until the specified position.

[0054] In this embodiment, see Figure 3 and Figure 5The design of the clamping part includes a nut 9 and rotating rods 10. The nut 9 has a three-section stepped platform, and its bottom end is engaged with symmetrically arranged limiting blocks on the top cover of the sleeve 6. The upper part of the limiting block contacts and limits the middle section of the nut 9, so that the nut 9 can only rotate and cannot move up and down. Two rotating rods 10 are located at the upper section of the nut 9, and two transmission rods are respectively located symmetrically on the upper cylindrical side of the nut 9, making it convenient for a person to hold the rotating rods 10 and rotate the nut 9. The screw of the clamping part is divided into a smooth round rod and a threaded rod with external threads. Partially; the screw is inserted into the nut 9, and the end of the screw extending out of the nut 9 is a smooth round rod with a pliers-shaped groove at its end, which fits into the clamping part and the sleeve 6. The elongated hole on the top cover of the sleeve 6 fits into the smooth round rod and limits the screw, so that the screw can only move up and down and cannot rotate; the inner side of the nut has an internal thread that matches the external thread of the threaded rod. When the rotating rods 10 on both sides of the nut are rotated, the nut rotates, and thus the internal thread of the nut rotates. The rotation of the internal thread will drive the threaded rod that it fits to move up and down.

[0055] This utility model relates to an installation fixture for assembling a left-hand advance missile slide 3 on a helicopter. It utilizes a clamping structure to install and position the left-hand advance missile slide 3 assembly. Current assembly procedures for the left-hand advance missile slide 3 require positioning and assembling a mandrel 2 inserted into the slide 3 and a steel wire compression spring 1 sleeved around the mandrel 2. Since the length of the steel wire compression spring 1 far exceeds the length of the mandrel 2, it is necessary to compress the steel wire compression spring 1 to the mounting pin hole 4 on the mandrel 2, and then use a cylindrical pin for positioning. However, there is currently no dedicated auxiliary fixture specifically for assembling the left-hand advance missile slide 3. The steel wire compression spring 1 is usually compressed to a designated position by manpower and then a cylindrical pin is inserted for positioning. However, manual assembly is very time-consuming and labor-intensive, and the work efficiency is not high. The whole assembly process is also quite cumbersome. At the same time, compressing the steel wire compression spring 1 by brute force may damage the mandrel 2 and the steel wire compression spring 1 during the assembly process. Therefore, the installation fixture designed in this scheme positions the left spring slide cylinder 3 through the support cylinder 5. The support cylinder 5 is fixed by a vise to facilitate subsequent assembly. Then, the guide cylinder 7 is set to position the steel wire compression spring 1 that needs to be compressed, so as to avoid inaccurate positioning of the inserted clamping part.

[0056] Unlike manual assembly, where the compression of the wire compression spring 1 to the designated mounting pin hole 4 fails to maintain its compressed state, this solution employs a clamping structure. Through a mating threaded structure, the rotational torque is converted into pressure to compress the wire compression spring 1. Rotating the nut causes the screw to move axially into the sleeve 6, with the bottom end of the screw pressing against the wire compression spring 1. Throughout this process, the compression state of the wire compression spring 1 is controllable and stable until it reaches the mounting pin hole 4 of the spindle 2. At this point, rotating the nut stops, and the screw ceases to press down. The wire compression spring 1 is stabilized in this compressed state, and then the cylindrical pin is inserted into the inner hole. In this scheme, the sleeve 6 and the guide cylinder 7 are grooved on the cylinder body, which makes it easy to observe the assembly state of the wire compression spring 1 and also makes it easy to insert the cylindrical pin into the inner hole. In this scheme, the support cylinder 5, sleeve 6, and guide cylinder 7 are used for positioning and fixing, and the clamping part applies force for installation. These four mechanisms cooperate with each other to realize the assembly of the helicopter left advance slide 3. The structure of the entire installation fixture is very simple, easy to install and disassemble, and not easy to damage the spindle 2 and the wire compression spring 1 and other parts.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
