Description

Technical Field

[0001] This utility model belongs to the field of airborne suspension launch technology, and in particular relates to a signal switching mechanism. Background Technology

[0002] Bushing installation typically requires a press-fit fixture for positioning, achieved through a press machine. Traditional press-fit fixtures generally use a positioning plate with circular pins through non-bushing press-fit holes to ensure the bushing's installation accuracy in the X and Y directions. Joint parts are crucial connectors for ensuring horizontal or vertical accuracy when connecting to upstream products. The installation accuracy of joint parts often relies on press-fitted bushings. Press-fitting bushings is a well-established technology, but sometimes these joint parts require press-fitting irregularly shaped bushings to meet installation requirements. Besides the X and Y directions, the Z-axis rotation direction also needs to be positioned to ensure the bushing meets the technical requirements for connection with the upstream product. Such bushings are widely used in the automotive and aerospace industries. However, pressing irregularly shaped bushings can present challenges in controlling horizontal or vertical accuracy. Utility Model Content

[0003] Utility Model Purpose

[0004] To address the problem of difficulty in controlling the horizontal or vertical accuracy during press-fitting of irregularly shaped bushings, this utility model provides a press-fitting fixture for ensuring the installation direction of bushings on joint parts.

[0005] Utility Model Technical Solution

[0006] A press-fit fixture for ensuring the installation direction of a bushing on a connector part includes a base plate and an upper plate above the base plate. The connector part is placed on the base plate such that the axis of the bushing hole to be press-fitted on the connector part is vertical. A positioning square bushing is fixed on the upper plate. The inner hole of the positioning square bushing corresponds to the position and has the same shape as the bushing hole to be press-fitted on the connector part. A pressure rod passes through the inner hole of the positioning square bushing. The bushing to be assembled is placed at the lower part of the pressure rod. When the pressure rod moves downward, it can press the bushing to be assembled onto the connector part.

[0007] Preferably, the bottom plate and the top plate are connected by a connecting plate, and both the bottom plate and the top plate are set horizontally.

[0008] Preferably, holes are provided at corresponding positions on the base plate and the joint parts for the bushing to be press-fitted.

[0009] Preferably, a positioning bushing is fixed inside the hole on the base plate.

[0010] Preferably, both ends of the connector part have holes for pressing and installing bushings.

[0011] Preferably, it also includes a positioning pin, which passes sequentially through the inner hole of the positioning bushing corresponding to the bushing hole to be pressed at one end of the connector part, and then extends into the inner hole of the corresponding positioning bushing; the positioning pin is removed after the pressing of the bushing to be pressed at the other end of the connector part is completed.

[0012] Preferably, the base plate has a boss at the location where the positioning bushing is provided, and the positioning bushing is disposed in the hole on the boss.

[0013] Preferably, the top surface of the base plate has a boss at a corresponding position to the groove in the middle of the connector part, and the boss is in clearance fit with the groove in the middle of the connector part.

[0014] Preferably, the positioning bushing is interference-fitted with the upper plate.

[0015] Preferably, the positioning pin and the inner hole of the positioning bushing and the positioning bushing are all clearance fit.

[0016] Advantages of this invention: The press-fitting fixture uses a double bushing guide method, which ensures the positioning of the press-fitted bushing in the X and Y directions, as well as the positional requirements in the Z-axis rotation direction. The product is easy to install and operate. The positioning parts all use bushings, which makes later maintenance and upkeep convenient and allows the fixture to be reused.

[0025] This utility model is achieved through the following technical solution.

[0026] A press-fit fixture for ensuring the installation direction of bushings on connector parts includes a base plate 1, a connecting plate 2, an upper plate 3, positioning square bushings 4, a pressure rod 5, positioning pins 6, positioning bushings 7, screws 10, cylindrical pin one 11, screws 12, and cylindrical pin two 13. The upper plate 3 is connected to the upper parts of the two connecting plates 2 at both ends by screws 10 and cylindrical pin one 11. The base plate 1 is connected to the bottom surface of the two connecting plates 2 by screws 12 and cylindrical pin two 13. The two positioning square bushings 4 are interference-fitted into the mounting holes on the upper plate 3. The positioning bushings 7 are interference-fitted with the base plate 1. The top surface of the base plate 1 has multiple bosses. The central boss has a clearance fit with the groove in the middle of the connector part 8. The bosses at both ends keep the two ends of the connector part 8 horizontal, thereby ensuring that the axis of the two bushing mounting holes on the connector part 8 is vertical. The positioning bushings 7 are press-fitted onto the bosses at both ends, maintaining consistency with the hole dimensions of the connector part 8. The positioning pin 6 passes through the inner hole of the positioning square bushing 4 and the bushing mounting hole at one end of the connector part 8 in sequence, and then inserts into the inner hole of the positioning bushing 7. The pressure rod 5 passes through the inner hole of the positioning square bushing 4 and the inner hole of the bushing to be assembled 9 to complete the positioning. The press applies force to the pressure rod 5 to assemble the bushing to be installed 9 with the connector part 8 to ensure the accuracy of its installation direction.

[0027] The positioning bushing 7 is square on all four sides and has an interference fit with the upper plate 3. The shape of the through hole in the center is consistent with the shape and position of the bushing mounting hole on the connector part.

[0028] The positioning pin 6 is a stepped shaft. Its upper shape matches the through hole shape of the positioning square bushing and is clearance-fitted with the positioning square bushing 4 on the upper plate 3. Its lower part is clearance-fitted with the positioning bushing 7 on the bottom plate.

[0029] The pressure rod 5 is a stepped shaft. Its upper part is clearance-fitted with the through hole on the positioning square bushing 4 on the upper plate 3, and its lower part is clearance-fitted with the inner hole of the bushing 9 to be assembled on the connector part 8, ensuring the installation direction and installation accuracy of the bushing 9 to be assembled and the connector part 8. The upper part of the pressure rod 5 can axially limit the bushing 9 to be assembled.

[0030] When pressing the bushing 9 to be assembled on the other side, two pressure rods 5 are required. Remove the positioning pin 6, insert one pressure rod 5 into the inner hole of the bushing already installed on the connector part 8, and use the other pressure rod 5 to press the bushing 9 to be assembled.

[0031] After use, the positioning bushings 4 and 7 of the press clamp need to be protected to prevent rust from appearing when reused.

[0032] The edges and sharp corners of the clamps should be rounded to improve safety.

[0033] Example

[0034] Prepare one connector part 8 and two bushings 9 to be assembled. Place the connector part 8 flat on the base plate 1, with a clearance fit between it and the boss. Align the bushing hole of the connector part 8 with the positioning bushing 7 of the base plate 1. Insert the positioning pin 6 through the positioning square bushing 4 of the upper plate 3, through the bushing hole of the connector part 8, and into the positioning bushing 7 of the base plate 1 to complete the positioning of the connector part 8 by the fixture. The pressure rod 5 passes through the positioning square bushing 4 and the bushing 9 to be assembled, completing the positioning of the bushing 9 by the fixture. The press applies force to the pressure rod 5 to assemble the bushing to be installed with the connector part, ensuring the required installation direction. The pressing method on the other side is the same. One pressure rod 5 is used instead of the positioning pin 6 to complete the positioning of the connector part 8, and the other pressure rod 5 completes the assembly of the bushing 9 to be assembled with the connector part 8, ensuring the required installation direction accuracy.
