Description

Technical Field

[0001] This utility model belongs to the field of tooling components technology, specifically relating to a transmitter limit block positioning and installation tool. Background Technology

[0002] When replacing the launch tube of an aircraft rocket launcher, the positioning block needs to be repositioned and installed on the launch tube wall. According to the product drawings, the axial distance between the front face of the positioning block and the front face of the ejector block is (0.3~0.8) mm. However, the positioning block is installed on the launch tube wall at an angle to the ejector block, and there is no suitable tool to measure the axial dimension between them, making positioning difficult and installation challenging. Using the tail end of the launch tube as a reference surface for positioning results in low installation efficiency and significant positional deviation, affecting work efficiency and product qualification rate. To ensure the positioning accuracy of the positioning block and improve assembly efficiency, a positioning and installation tool for the launcher positioning block needs to be designed, capable of quick and accurate positioning and facilitating the assembly of the positioning block. Utility Model Content

[0003] The purpose of this utility model is to provide a transmitter limit block positioning and installation tool to ensure the positional accuracy of the limit block installation, improve assembly efficiency and product qualification rate.

[0004] The technical solution of this utility model is as follows: A transmitter limiting block positioning and installation tool includes a positioning bushing, a ball spring screw, a mounting sleeve, and a guide sleeve; the positioning bushing and the ball spring screw are connected by threads, the positioning bushing is installed inside the transmitter tube, and is fixed by the reaction force generated by the ball spring screw for axial positioning; the mounting sleeve and the guide sleeve are pressed together by countersunk screws and inserted into the transmitter tube wall for circumferential positioning; the mounting sleeve has a slot that fits clearance with the limiting block, the limiting block is placed into the slot of the mounting sleeve, the mounting hole is drilled by guiding the hole of the limiting block, and the limiting block is fixed to the transmitter tube wall with screws; the lower end of the positioning bushing has a lower slot that fits clearance with the mounting sleeve.

[0005] The positioning bushing has a through hole in the middle for easy operation when installing the limiting block with tools. To ensure the positional accuracy of the limiting block installation, the following aspects are controlled: ΦA is the diameter of the positioning bushing installed inside the launch tube. This dimension is designed based on the inner diameter of the launch tube, requiring that the positioning bushing installed inside the launch tube has no radial movement and can rotate flexibly. The installation diameter ΦA of the positioning bushing is clearance-fitted with the launch tube; the handle diameter ΦB of the positioning bushing has three threaded holes for installing ball spring screws; the upper end of the positioning bushing has an "L"-shaped groove larger than the ejector block for installing the ejector block. The D surface of the positioning bushing that contacts the ejector block is the reference surface. After the positioning bushing is installed into the launch tube, the reaction force of the ball spring screw brings the D surface tightly against the front end face of the ejector block. The C surface that contacts the limiting block is machined with the D surface as the reference surface, and the axial distance between the C surface and the D surface is (0.3~0.8) mm. This design reduces the radial movement of the positioning bushing in the launch tube while simultaneously achieving axial positioning of the positioning bushing.

[0006] The extension length of the ball spring screw in the positioning bushing is adjustable, and the steel ball of the ball spring screw acts on the rear end face of the transmitter rear cover assembly.

[0007] To determine the circumferential position of the positioning bushing, a guide sleeve with rapid positioning capability was designed. The guide sleeve and the mounting sleeve are press-fitted together with countersunk screws. The guide sleeve is installed into the slot of the transmitter rear cover assembly with a clearance fit, while the mounting sleeve is also installed into the lower slot of the positioning bushing with a clearance fit. This design restricts the circumferential rotation of the positioning bushing.

[0008] The beneficial effects of this utility model are as follows: Firstly, the installation position of the limiting block is ensured by the mutual cooperation of the tooling slots, solving the problem of not being able to measure the axial dimension with tools, and ensuring that the installation position of the limiting block meets the technical requirements. Secondly, the work that previously required repeated disassembly of the rear cover assembly for marking and positioning can now be completed with a single disassembly, saving labor costs and improving work efficiency.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] The present invention provides a transmitter limiting block positioning and installation tool, such as... Figure 1-2 As shown, it includes a positioning bushing 4, a mounting sleeve 5, a guide sleeve 6, two countersunk screws 7, and three ball spring screws 8. The positioning bushing 4 and the ball spring screws 8 are connected by threads, and the mounting sleeve 5 and the guide sleeve 6 are press-fitted together by the countersunk screws 7. The lower end of the positioning bushing 4 has a groove that mates with the mounting sleeve 5, and the mounting sleeve and the groove are clearance-fitted.

[0014] like Figure 2 As shown, the positioning bushing has a through hole in the middle. The mounting diameter ΦA of the positioning bushing is clearance-fitted with the launching tube, with a clearance not exceeding 0.2mm. The handle diameter ΦB of the positioning bushing has three threaded holes for installing ball spring screws. The ball spring screw 8 has an adjustable extension length, and the steel ball of the ball spring screw acts on the rear end face of the launcher rear cover assembly 3. The upper end of the positioning bushing has an "L"-shaped slot larger than the ejector block 2 for installation of the ejector block 2, with a large clearance fit between them.

[0015] The guide sleeve 6 is installed into the rear cover assembly groove with a clearance fit of (0.05~0.10) mm. Simultaneously, the mounting sleeve 5 is installed into the lower groove of the positioning bushing with a clearance fit of (0.05~0.10) mm. The clearance fit between the limiting block 9 and the mounting sleeve groove is (0.05~0.10) mm. The axial distance between the C-surface of the positioning bushing 4, which contacts the limiting block 9, and the D-surface, which contacts the ejector block 2, is (0.3~0.8) mm.

[0016] like Figure 3 As shown, before use, use a tool to rotate the ball spring screw 8 to retract the steel ball into the threaded hole.

[0017] During use, align the upper slot of the positioning sleeve 4 with the ejector block 2 and insert it into the launch tube 10. Rotate the positioning sleeve 4 clockwise to align the lower slot of the positioning sleeve 4 with the slot of the rear cover assembly 3. Insert the assembled guide sleeve 6 into the slot of the rear cover assembly 3, and simultaneously insert the mounting sleeve 5 into the lower slot of the positioning sleeve 4. Use a tool to rotate the ball spring screw 8 so that the steel ball presses against the rear end face of the rear cover assembly 3. Place the limiting block 9 into the slot of the mounting sleeve 5, select a drill bit that matches the hole position of the limiting block 9, and drill the mounting hole through the guide of the hole position of the limiting block 9. Then, fix the limiting block to the launch tube wall with screws.

[0018] The use of this utility model's limit block positioning and installation tool effectively ensures the positional accuracy of the limit block installation, improving assembly efficiency and product qualification rate. Simultaneously, it solves the problem of repeatedly disassembling the rear cover assembly required for marking and positioning, saving labor costs and improving work efficiency.
