Description

Technical Field

[0001] This utility model relates to the field of pressure sleeve tooling technology, and in particular to a pressure sleeve tooling for a bracket. Background Technology

[0002] In modern industrial production, the beam assembly is a key component in many mechanical devices and structures, and its performance and quality directly affect the stability and reliability of the entire system. The beam assembly typically needs to cooperate with various supports to achieve the connection and support functions between different components. The pressure sleeves on the supports play an important role in buffering, positioning, and enhancing connection stability.

[0003] Chinese utility model patent CN218082515U discloses a tooling for pressing steel sleeves for urban rail car sleepers, including a frame; a platform installed on the upper part of the frame to support the sleeper beam; a gantry frame spanning across the platform along the width direction above the platform, and a working area for pressing steel sleeves is formed between the lower surface of the gantry frame and the upper surface of the platform, and a pressure head that can move toward the upper surface of the platform is installed on the lower surface of the gantry frame; the two ends of the gantry frame are slidably connected to the platform through sliding pairs so that the gantry frame drives the pressure head to switch the pressing position.

[0004] The aforementioned tooling addresses some shortcomings of existing technologies, but it still has some drawbacks in practical use. For example, during the pressing process, the steel sleeve needs to be placed inside the mounting hole. If the steel sleeve is misaligned, it may become stuck in the mounting hole, forcing the pressing operation to stop. Furthermore, forcibly pressing in a misaligned steel sleeve can easily cause deformation, severely impacting production progress. Therefore, we propose a pressing tooling for the bracket.

[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] Please refer to Figures 1 to 6As shown, an embodiment of this utility model provides a bushing pressing fixture, including a base 1 and a top seat 2. The base 1 and the top seat 2 are fixedly connected by a guide post 101. A movable plate 4 is movably arranged between the base 1 and the top seat 2. A mounting seat 6 is fixedly installed at the bottom of the movable plate 4. A hydraulic cylinder 3 is fixedly installed at the top of the top seat 2. The bottom of the piston rod of the hydraulic cylinder 3 is fixedly connected to the top of the movable plate 4. A pressing head 7 is fixedly connected to the bottom of the mounting seat 6. A pressing platform 8 is fixedly connected to the top of the base 1. A guiding mechanism 9 for guiding the bushing is provided inside the pressing platform 8. The guiding mechanism 9 includes a reset member and a guide member with an adjustable inner diameter. The guide member is installed on the top of the reset member. A circular hole 801 is opened at the top of the pressing platform 8. The circular hole 801 is located directly below the pressing head 7. The upper end of the guide member can slide out through the circular hole 801.

[0028] When the hydraulic cylinder 3 is working, the piston rod extends or retracts, causing the movable plate 4 to move up and down along the guide post 101. The movement of the movable plate 4 causes the mounting base 6 and the pressure head 7 to move synchronously. The guide component in the guiding mechanism 9 can move up and down through the reset component, and the inner diameter of the guide component is adjustable. When the bushing is placed on the guide component, the guide component can position and guide the bushing so that it can be accurately pressed into the target position by the pressure head 7.

[0029] In this embodiment, the reset component includes a sleeve 901 and a movable rod 902. The sleeve 901 is fixedly installed inside the pressing platform 8. The lower end of the movable rod 902 is slidably inserted into the sleeve 901. A limiting ring 903 is fixedly connected to the bottom of the movable rod 902 to prevent the movable rod 902 from disengaging from the sleeve 901. A second spring 904 is provided inside the sleeve 901. The top of the second spring 904 abuts against the bottom of the limiting ring 903, and the bottom of the second spring 904 presses against the inner bottom of the sleeve 901.

[0030] When the pressure head 7 presses down on the bushing, the bushing applies pressure to the guide, and the guide drives the movable rod 902 to move downward against the elastic force of the second spring 904. The sleeve 901 plays a guiding role for the movable rod 902. When the pressure head 7 rises, the elastic force of the second spring 904 causes the movable rod 902 and the guide to return to their original positions.

[0031] In this embodiment, the guide includes a three-jaw chuck 906, which is fixedly installed on the top of the movable rod 902. Guide rods 905 are fixedly welded to the three jaws of the three-jaw chuck 906.

[0032] By adjusting the three-jaw chuck 906, the distance between the three jaws can be changed, thereby adjusting the inner diameter of the guide to accommodate bushings of different sizes. The guide rod 905 guides and straightens the bushing, ensuring its stability during the pressing process.

[0033] In this embodiment, one end of the adjusting gear of the three-jaw chuck 906 is fixedly connected to an adjusting rod 9061, and a waist hole 802 is opened on the side of the pressing platform 8. The end of the adjusting rod 9061 away from the three-jaw chuck 906 slides through the waist hole 802.

[0034] The operator can rotate the adjusting rod 9061 to drive the adjusting gear of the three-jaw chuck 906 to rotate, thereby adjusting the distance between the three jaws of the three-jaw chuck 906 and thus adjusting the inner diameter. The operation is convenient and can be adjusted from outside the tooling without disassembling other parts.

[0035] In this embodiment, both ends of the movable plate 4 are provided with fixing members 5. The fixing members 5 include a housing 501 and a pressure block 502. The housing 501 is fixedly installed at the bottom of the movable plate 4. The upper end of the pressure block 502 is slidably disposed inside the housing 501. The top of the pressure block 502 is fixedly connected with a limiting block 5021 to prevent the pressure block 502 from detaching from the inside of the housing 501. A first spring 503 is provided inside the housing 501. The bottom of the first spring 503 presses against the top of the limiting block 5021, and the top of the first spring 503 abuts against the inner top of the housing 501.

[0036] During the pressing process, when the movable plate 4 moves downward, the pressing block 502 first contacts both sides of the bracket, applying pre-fixation to the bracket.

[0037] In this embodiment, a guide rod 504 is fixedly connected to the top of the limiting block 5021. The upper end of the guide rod 504 slides through the housing 501 and the movable plate 4. The first spring 503 is sleeved on the guide rod 504.

[0038] The guide rod 504 provides a more stable guiding effect for the sliding of the pressure block 502, and also ensures the stability of the first spring 503 during compression and extension, preventing the spring from tilting and affecting its normal operation.

[0039] In this embodiment, a sliding sleeve is fixedly installed on the movable plate 4, and the sliding sleeve is slidably fitted onto the guide post 101. The sliding sleeve cooperates with the guide post 101 to provide precise guidance for the up and down movement of the movable plate 4, ensuring the stability of the movable plate 4 during movement, so that the pressure head 7 can accurately perform the pressing operation on the bushing, thereby improving the pressing accuracy.

[0040] Working principle:

[0041] Based on the bushing size, the distance between the three jaws of the three-jaw chuck 906 is adjusted by rotating the adjusting rod 9061, thereby completing the inner diameter adjustment so that the guide rod 905 can fit the bushing.

[0042] Place the bracket on the pressing platform 8 so that the guide rod 905 passes through the bushing mounting hole on the bracket;

[0043] Place the bushing onto the guide rod 905.

[0044] Hydraulic cylinder 3 is activated, and its piston rod extends, causing movable plate 4 to move downward along guide post 101. Movable plate 4 causes mounting base 6 and pressure head 7 to descend synchronously. Pressure head 7 contacts bushing and applies downward pressure, while simultaneously pushing guide and movable rod 902 to slide downward within sleeve 901 against the elastic force of second spring 904.

[0045] After the pressing is completed, the piston rod of the hydraulic cylinder 3 retracts, causing the movable plate 4, mounting base 6 and pressing head 7 to rise. The second spring 904 resets the guide and movable rod 902, completing one pressing operation.

[0046] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
