[0002] The cylinder bracket is an important component for cylinder installation. One type of cylinder bracket is shown in the attached figure. Figure 1 and attached Figure 2 As shown, the cylinder bracket 10 is welded together from a base plate 10.1, two ear plates 10.2 arranged side by side at one end of the base plate, a connecting plate 10.3 on the back of the ear plates for connecting the two ear plates, and a reinforcing rib plate 10.4 on the back of the connecting plate for connecting the base plate and the connecting plate. The two ear plates are provided with shaft holes. The technical requirements are that the two ear plates are parallel to each other and perpendicular to the base plate and the connecting plate. The rib plate is located in the middle of the connecting plate and is made of the same material as the base plate.

[0003] The existing welding fixtures for hydraulic cylinder brackets, which are made by welding two ear plates to a base plate, cannot meet the above-mentioned processing requirements of hydraulic cylinder brackets. For example, the pitching hydraulic cylinder bracket welding fixture applied for by the applicant on 2021-05-25, application number CN202121142945.9, can only meet the positioning welding of the ear plates on the base plate, and cannot complete the positioning welding of the connecting plate and the reinforcing rib plate.

[0004] Based on this, this application provides a novel hydraulic cylinder bracket riveting and welding fixture with high positioning accuracy that can simultaneously meet the welding requirements of the ear plate, connecting plate, and reinforcing rib plate to the base plate, in order to solve the above problems.

[0005] This utility model aims to solve the technical problems existing in the prior art. To this end, this utility model provides a new type of hydraulic cylinder bracket riveting and welding fixture with high positioning accuracy, which can simultaneously meet the welding requirements of the ear plate, connecting plate, and reinforcing rib plate to the base plate.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A novel hydraulic cylinder bracket riveting and welding fixture is provided, comprising a base, an ear plate positioning assembly, and a stiffener positioning assembly. The base has at least two positioning pins that match the mounting holes on the base plate of the hydraulic cylinder bracket for positioning the base plate. The ear plate positioning assembly includes a first hinge seat at one end of the base and a first flip block rotatably connected to the first hinge seat at one end. Positioning grooves are provided on both sides of the end of the first flip block away from the first hinge seat for positioning two ear plates. The first flip block also has pin holes, through which pins pass to position the ear plates via the pin holes and shaft holes on the ear plates. The stiffener positioning assembly includes a second hinge seat at the other end of the base and a second flip block rotatably connected to the second hinge seat at one end. The second flip block has a stop for positioning the reinforcing stiffener.

[0008] In some alternative embodiments, multiple permanent magnets are also embedded on the contact surface of the first flipping block with the ear plate for attracting the ear plate.

[0009] In some alternative embodiments, the end of the first flip block away from the first hinge seat extends out of the connecting plate, and an extension block is provided at its bottom to form a limiting plane for limiting the connecting plate.

[0010] In some optional embodiments, the stop is provided with a long strip-shaped limiting plate with an "L"-shaped cross-section, and the limiting plate and the stop together form a limiting groove for limiting the reinforcing rib plate.

[0011] In some optional embodiments, the first hinge seat and the second hinge seat are further provided with a first limiting plate and a second limiting plate, respectively, to prevent the first flip block and the second flip block from over-flipping.

[0012] In some alternative embodiments, the first hinge seat is provided with a third limiting plate to ensure that the first flip block is in a fixed position after the ear plate is positioned.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a base to position the base plate, uses an ear plate positioning assembly to position the ear plate, uses the ear plate to position the connecting plate, and uses the connecting plate and the rib plate positioning assembly to position the reinforcing rib plate, thereby achieving precise positioning and riveting of each component of the hydraulic cylinder bracket, resulting in high welding precision and good product consistency.

[0015] 2. The extension block provided on the first flipping block can form a limiting plane to limit the position of the connecting plate, ensuring the position of the connecting plate without the need to manually press the connecting plate against the ear plate.

[0016] 3. The third limiting plate is designed so that after the first flipping block is put down, its positioning groove is exactly in the set position of the ear plate, which reduces the difficulty of positioning the ear plate. Attached Figure Description

[0033] Example 1

[0034] As attached Figure 3 To be continued Figure 6 As shown, this embodiment provides a novel hydraulic cylinder bracket riveting and welding fixture, including a base 1, an ear plate positioning assembly 2, and a stiffener plate positioning assembly 3, wherein:

[0035] The base 1 is provided with at least two positioning posts 1.1 that match the mounting holes on the base plate 10.1 of the hydraulic cylinder bracket, for positioning the base plate. Preferably, in this embodiment, there are two positioning posts, which are arranged diagonally, and the top of the positioning posts is provided with a chamfer for guidance, which facilitates the quick placement of the base plate.

[0036] The ear plate positioning assembly 2 includes a first hinge seat 2.1 located at one end of the base 1 and a first flip block 2.2 rotatably connected to the first hinge seat 2.1 at one end. The first flip block 2.2 has positioning grooves 2.2.1 on both sides of the end away from the first hinge seat 2.1. The positioning grooves are vertical through grooves. The two side surfaces a formed on the first flip block 2.2 serve as positioning surfaces for the ear plate (the distance between the two side surfaces is equal to the set distance between the two ear plates). The end face b formed on the first flip block 2.2 serves as the positioning surface for the side surface of the ear plate. Therefore, the positioning grooves can position the ear plate in the width and length directions of the first flip block. In order to achieve vertical positioning of the ear plate, a pin hole 2.2.0 is also provided on the first flip block 2.2. The ear plate is positioned by passing a pin 4 through the pin hole 2.2.0 and the shaft hole on the ear plate 10.2, thus completing the position fixation of the ear plate.

[0037] Preferably, in this embodiment, multiple permanent magnets 5 are also embedded in the contact surface between the first flipping block 2.2 and the ear plate, preferably strong magnets, to attract the ear plate and ensure that the ear plate can be tightly attached to the first flipping block.

[0038] The stiffener positioning assembly 3 includes a second hinge seat 3.1 located at the other end of the base 1 and a second flip block 3.2 rotatably connected to the second hinge seat 3.1 at one end. The second flip block 3.2 is provided with a stop 3.3 for positioning the stiffener 10.4. Specifically, in this embodiment, the position of the stop 3.3 is such that the stiffener 10.4 is exactly on the central axis of the two ear plates 10.2, that is, located in the middle of the connecting plate.

[0039] Preferably, in this embodiment, a first limiting plate 2.1.1 and a second limiting plate 3.1.1 are respectively provided in the first hinge seat 2.1 and the second hinge seat 3.1, which are used to prevent the first flipping block 2.2 and the second flipping block 3.2 from over-flipping. The states of the first flipping block 2.2 and the second flipping block 3.2 after flipping are shown in the attached figure. Figure 5 As shown, this allows for quick and easy placement of the first and second flip blocks.

[0040] In practical use: First, position the base plate on the base; then, place the two ear plates in the positioning groove of the first flip block using pins, rotate the first flip block until the ear plates contact the base plate, spot weld the base plate and ear plates to complete the initial fixation of the ear plates; then place the connecting plate tightly against the ear plates, adjust the position of its two ends, spot weld the connecting plate and ear plates to complete the initial fixation of the connecting plate; then put down the second flip block, position the reinforcing rib plate using the abutment on the second flip block as a positioning point, and place it tightly against the connecting plate, spot weld the reinforcing rib plate and base plate to complete the initial fixation of the reinforcing rib plate; then complete the supplementary welding between each component. After the supplementary welding is completed, flip open the first and second flip blocks, take out the workpiece, and fully weld the connection seams between each component.

[0041] Example 2

[0042] Based on Example 1, as shown in the appendix Figure 3 To be continued Figure 6 As shown, in this embodiment, a connecting plate 10.3 extends from the end of the first flipping block 2.2 away from the first hinge seat 2.1, and an extension block 2.2.2 is provided at its bottom to form a limiting plane c for limiting the connecting plate 10.3. This design allows the extension block to position the connecting plate, ensuring the position of the connecting plate without manually pressing the connecting plate against the ear plate.

[0043] Example 3

[0044] Based on Example 1, Example 2, or Example 3, as shown in the appendix Figure 3 To be continued Figure 5 As shown, in this embodiment, a long, L-shaped limiting plate 3.4 is provided on the stop 3.3. The limiting plate 3.4 and the stop 3.3 form a limiting groove for limiting the reinforcing rib plate 10.4. This design can ensure the position of the reinforcing rib plate without manually pressing the reinforcing rib plate against the stop.

[0045] Example 4

[0046] Based on any of the above embodiments, as shown in the appendix Figure 3 and attached Figure 5 As shown, in this embodiment, a third limiting plate 2.1.2 is provided inside the first hinge seat 2.1 to ensure that the first flipping block 2.2 is in a fixed position after the ear plate is positioned. This design ensures that after the first flipping block is lowered, its positioning groove is exactly in the set position of the ear plate, reducing the operational difficulty of positioning the ear plate and making it easier to lower the first flipping block and then place the ear plate.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
