Description

Technical Field

[0001] This utility model relates to a pressing tool, specifically a pressing tool. Background Technology

[0002] The ear plate of construction machinery is a key component that bears various torques and is subject to severe wear. Pressing in a special bushing reduces wear in this area. This bushing tooling mainly ensures that the bushing is smoothly pressed into the machine at room temperature using a hydraulic jack under an interference fit. However, when pressing in directly with a jack, it is difficult to guarantee that the center symmetry of the hole will not shift during pressing, which can cause the bushing to shift and affect subsequent operations. Using a large bushing press would increase costs. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a pressing tool. This utility model is easy to manufacture, effectively reduces the lifting force of the hydraulic cylinder during pressing, thus preventing deviations in the symmetry of the ear plate of the structure. It can effectively save costs, reduce the high cost investment of large pressing machines, and facilitate widespread use.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a pressing tool, including a top plate, three positioning plates are fixed to one end of the lower surface of the top plate, the three positioning plates are arranged side by side, wherein the left and middle positioning plates are fixed to the ear plate by fixing sleeves, and the right positioning plate is provided with a guide sleeve, the guide sleeve holding the bushing; a vertical plate is fixed to the other end of the lower surface of the top plate, and a positioning rod for positioning a jack is fixed to the vertical plate, the jack pressing the bushing into the ear plate hole.

[0005] The positioning plate is provided with two short ribs, and the upright plate is provided with two long ribs.

[0006] The number of positioning rods is 2.

[0007] The positioning plate is provided with a round hole.

[0008] The positioning plate is provided with bolt holes, and bolts are fitted into the bolt holes.

[0009] A transition plate is also provided, which has a positioning step that extends into the bushing, and the back of the transition plate is used to contact the jack.

[0010] A pad is also provided, the pad having two through holes that pass through the positioning rod.

[0011] In summary, this utility model achieves the following technical effects:

[0012] This utility model involves hoisting the tooling boom and the cylinder ear plate to be installed, inserting the fixing sleeve, and locking it with M20*60 fully threaded bolts. The pad block and the cylinder jack are placed on the positioning bar, and the transition block, bushing, and guide sleeve are installed in sequence. After preparation, the hydraulic jack is started to slowly press the bushing into the ear plate of the structural component to prevent the ear plate from becoming asymmetrical due to the pressure of the hydraulic jack.

[0024] Example:

[0025] Figure 1 It is a type of press-fit tooling. Figure 2 yes Figure 1 Left view, Figure 3 yes Figure 1 The bottom view includes a top plate 1. Three positioning plates 2 are fixed to one end of the lower surface of the top plate 1. The three positioning plates 2 are arranged side by side. The left and middle positioning plates 2 are fixed to the ear plates by fixing sleeves 9. The right positioning plate 2 is provided with a guide sleeve 10, and the guide sleeve 10 holds the bushing 11. A vertical plate 5 is fixed to the other end of the lower surface of the top plate 1. The vertical plate 5 is fixed with a positioning rod 8 for positioning a jack 13. The jack 13 presses the bushing 11 into the ear plate hole.

[0026] The top plate 1 is a rectangular panel used for assembling all components. A lifting plate 4 is installed on the upper surface of the top plate 1 for hoisting, allowing the fixture to be lifted for use. There are three positioning plates 2. The left-side mating fixing sleeve 9 is positioned on the hole of one of the two ear plates, and then locked in place by the middle positioning plate 2. Each positioning plate 2 has two short ribs 3, and the upright plate 5 has two long ribs 6. These ribs enhance the overall strength of the fixture. The upright plate 5 is used to install a jack. The jack is manual for easy operation and installation. The thrust of the manual hydraulic jack centers the bushing and presses it into the inner wall of the ear plate. There are two positioning rods 8, used to position the jack, keeping its center coaxial with the hole in the ear plate, ensuring even force application. The guide sleeve 10 is fitted with the bushing 11 to be pressed in, ensuring the bushing is aligned with the ear plate hole. The guide sleeve is then inserted into the ear plate hole.

[0027] Figure 4 This is a schematic diagram of the positioning plate. The positioning plate 2 is provided with a circular hole 201 for assembling the fixing sleeve 9, thereby making it coaxial with the plate hole of the ear plate, or for assembling the guide sleeve 10 to guide the bushing. The fixing sleeve is inserted into the circular holes of the ear plate and the positioning plate to ensure that the tooling is concentric with the main frame ear plate.

[0028] The positioning plate 2 is provided with bolt holes 202, and bolts 7 are fitted into the bolt holes 202. The bolts 7 on the left positioning plate and the bolts 7 on the middle positioning plate are used to fix this tooling. Fixing this tooling to the ear plate can ensure stability during use and maintain the coaxiality of the holes, thus ensuring the concentricity after the bushing is installed.

[0029] Figure 5 This is a schematic diagram of the tooling in use. A transition plate 12 is also provided, with a positioning step extending into the bushing 11. The back of the transition plate 12 is used to contact the jack 13. The transition plate serves two purposes: firstly, the positioning step positions the bushing and the transition plate; secondly, it allows the bushing to directly contact the jack, preventing damage to the bushing.

[0030] A pad 14 is also provided, which has two through holes that pass through the positioning rod 8. When the stroke of the jack is insufficient, the pad can be used to extend the stroke; when the stroke is sufficient, the pad is not needed.

[0031] The components of this utility model are connected by welding and are designed for suspension.

[0032] Working principle:

[0033] The crane lifts the tooling using the lifting plate 4 and places it on the ear plate;

[0034] Align the round hole 201 of the positioning plate 2 on the left side of this fixture with the plate hole of the ear plate, and install the fixing sleeve 9 in the two holes. At this time, the positioning plate and the ear plate are aligned, and the round hole 201 is coaxial with the plate hole. Tighten the bolt 7 of the left positioning plate and the bolt 7 of the middle positioning plate to fix it. At this time, the fixture is fixed.

[0035] Install the guide sleeve 10 into the round hole 201 of the right positioning plate 2 and the plate hole of the ear plate. Then install the bushing 11 into the guide sleeve 10. Next, install the positioning step of the transition plate 12 into the bushing 11. If necessary, install the jack 13 with the pad 14 on the positioning rod 8. Start the jack 13. The drive rod of the jack 13 contacts the transition plate 12 and presses the bushing 11 into the plate hole of the ear plate.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
