Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for hydraulic cylinder production, and in particular relates to a cylinder assembly and tilting device. Background Technology

[0002] A hydraulic cylinder mainly consists of a cylinder body and a piston rod. When assembling a hydraulic cylinder, the cylinder body is first fixed, and then the piston rod is inserted from the open end of the cylinder body. During assembly, because the piston rod is relatively long and thin, in order to reduce the risk of piston rod bending, the cylinder body needs to be kept vertical, and then the piston rod is inserted vertically into the cylinder body.

[0003] Existing assembly methods mostly use manual straightening to keep the cylinder upright. However, for cylinders with large diameters and heavy weights, multiple people are needed to work together to support the outer wall of the cylinder. For cylinders with non-flat bottoms, the verticality error is large and the efficiency is low. There are also automatic tilting devices that can tilt the cylinder 90°. The tilting is achieved by using a rack and pinion to drive the gears. The rack and pinion have a large torque, short service life, and high cost. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a cylinder assembly and flipping device that uses a hydraulic cylinder to achieve a 90° rotation of the cylinder and keeps the rotated cylinder upright. It is simple to operate and has low cost.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed:

[0006] A cylinder assembly tilting device, comprising:

[0007] The support unit has a base on it, and a support plate on the base. One end of the bottom surface of the support plate is rotatably connected to one end of the base. The other end of the base is rotatably equipped with a hydraulic cylinder. The output end of the hydraulic cylinder is rotatably connected to the middle of the bottom surface of the support plate. One end of the support plate is equipped with a support plate, and a support seat is provided on one side of the support plate at intervals. The top of the support plate is recessed to form a V-shaped opening for supporting the cylinder body.

[0008] The limiting part is provided in a set and is symmetrically arranged on both sides of the support base. The limiting part includes an inclined plate parallel to the inner inclined surface of the support base. A U-shaped frame is provided on one side of the inclined plate, and the length of the upper support arm of the U-shaped frame is greater than the length of the lower support arm. The opening of the U-shaped frame faces the support base. The lower horizontal part of the U-shaped frame is horizontally inserted through one side of the support base and connected to the inclined plate. A limiting plate is rotatably provided on the upper horizontal part. A locking bolt is provided at the connection between the limiting plate and one end of the upper horizontal part of the U-shaped frame. A spring is provided on the lower horizontal part of the U-shaped frame. One end of the spring abuts against the inclined plate and the other end abuts against the inner inclined surface of the support base.

[0009] Furthermore, a set of support seats are provided at intervals, and the inner inclined surface of the support seat is recessed with a receiving groove for accommodating the inclined plate.

[0010] Furthermore, stepped holes are provided on both sides of the support base. The larger end of the stepped hole is connected to the receiving groove, and the smaller end is connected to the outer wall of the support base. The other end of the spring abuts against the connection between the larger and smaller ends of the stepped hole.

[0011] Furthermore, the small end of the stepped hole has a square structure, and the cross-section of the lower horizontal part of the U-shaped frame matches the shape of the small end of the stepped hole.

[0012] Furthermore, in the initial state, there is a predetermined angle between the cylinder body of the hydraulic cylinder and the base.

[0013] Furthermore, a support strip is provided on the other side of the tray, and a cushioning pad is provided on one side of the support strip.

[0014] Furthermore, a rubber pad is provided on one side of the limiting plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] A support plate is vertically installed at one end of the support plate. The support plate abuts against the lower end of the cylinder body and supports one side of the outer wall of the cylinder body in conjunction with the V-shaped opening of the support seat. The limiting plate presses the other side of the outer wall of the cylinder body to ensure that the cylinder body remains vertical after being flipped. Under the push of the hydraulic cylinder, the support plate is flipped 90°, so that the cylinder body is in a vertical state, which replaces the manual holding of the cylinder body. The operation is simple and efficient. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0025] like Figure 1 As shown in the figure, this embodiment provides a cylinder assembly tilting device for assembling a hydraulic cylinder, so that the cylinder body 1 is in a vertical state during assembly, allowing the piston to be inserted vertically into the cylinder body 1 and reducing the risk of piston rod bending. The device includes a support part 10 and a limiting part 20 provided on the support part 10. The support part 10 is used to support the outer wall of the cylinder body 1, and the limiting part 20 is used to limit the outer wall of the cylinder body 1 when the cylinder body 1 is in a vertical state.

[0026] like Figures 1-2 As shown, the support part 10 includes a base 11, a support plate 12, a support plate 13, a support seat 14, and a hydraulic cylinder 15. The base 11 has a cuboid structure and is fixed to the ground. One end of the bottom surface of the support plate 12 is rotatably connected to the top surface of the base 11, and the rotatable connection position is at a predetermined distance from one end of the top surface of the base 11, the distance corresponding to the length of the support plate 13. The hydraulic cylinder 15 is rotatably disposed at the other end of the top surface of the base 11, and the output end of the hydraulic cylinder 15 faces one end of the base 11 and is connected to the top surface of the base 11. The support plate 12 has an included angle, and the middle part of the bottom surface of the support plate 12 is rotatably connected to the output end of the hydraulic cylinder 15 so that when the hydraulic cylinder 15 extends, it pushes the support plate 12 upward, thereby pushing the cylinder 1 to a vertical state; the support plate 13 is vertically disposed at one end of the support plate 12, and is used to support the lower end of the cylinder 1 when the cylinder 1 is in a vertical state; the support seat 14 is disposed on the top surface of the support plate 12 and is spaced apart from the support plate 13, and the upper end of the support seat 14 is recessed downward to form a V-shaped opening for supporting the cylinder 1.

[0027] like Figures 3-5As shown, a set of limiting parts 20 are provided, symmetrically arranged on both sides of the support base 14. The limiting part 20 includes an inclined plate 21, a U-shaped frame 22, a limiting plate 23, a locking bolt 24, and a spring 25. The inclined plate 21 is located on the inner inclined surface of the support base 14, and the inclined plate 21 is parallel to the inner inclined surface of the opening of the support base 14. The U-shaped frame 22 is horizontally arranged on the outer side of the support base 14, and the opening of the U-shaped frame 22 faces the support base 14. The lower support arm of the U-shaped frame 22 horizontally passes through the side wall of the support base 14 and connects to the inclined plate 21 facing the inner side of the support base 14. On one side of the inclined plane, the lower support arm of the U-shaped frame 22 is slidably connected to the support base 14, and the upper support arm of the U-shaped frame 22 is parallel to the upper end of the support base 14 and faces the opening direction of the support base 14. The outer wall of the limiting plate 23 is provided with a support protruding upward. The locking bolt 24 is used to lock the limiting plate 23 to one end of the upper support arm of the U-shaped frame 22 so as to fix the position of the limiting plate 23 and make the limiting plate 23 detachably provided at one end of the upper support arm of the U-shaped frame 22. Preferably, to adapt to a smaller diameter cylinder 1, this can be achieved by increasing the length of the support.

[0028] The inner inclined surface of the support base 14 is recessed with a receiving groove 141. The upper and lower ends of the receiving groove 141 are parallel to the horizontal plane and are used to receive the inclined plate 21 to increase the receiving space at the opening of the support base 14 to accommodate cylinders 1 with different outer diameters. The outer side of the support base 14 is provided with a stepped hole 142 extending inward. The large end of the stepped hole 142 is connected to the receiving groove 141, and the small end is connected to the outer wall of the support base 14. The spring 25 is inserted through the lower support arm of the U-shaped frame 22, and one end of the spring 25 abuts against the side of the inclined plate 21 facing the receiving groove 141, and the other end abuts against the connection between the large end and the small end of the stepped hole 142. The lower cross section of the stepped hole 142 has a directional structure. The cross section of the lower horizontal part of the U-shaped frame 22 is adapted to the shape of the small end of the stepped hole 142 to prevent the U-shaped frame 22 from rotating.

[0029] Specific usage process:

[0030] Using hoisting equipment, cylinder 1 is horizontally lowered onto support base 14, with the closed end of cylinder 1 abutting against support plate 13. The inner wall of support base 14 supports cylinder 1. During the downward lowering of cylinder 1 into support base 14, the lower outer wall of cylinder 1 pushes the upper end of U-shaped frame 22 to move outward towards support base 14, allowing cylinder 1 to enter support base 14. When the lower outer wall of cylinder 1 presses against inclined plate 21, inclined plate 21 is accommodated in receiving groove 141. One side of limiting plate 23 is then aligned with the upper outer wall of cylinder 1, and the other side of limiting plate 23 is locked to the upper support arm of U-shaped frame 22 using locking bolts 25, thus lowering cylinder 1. Finally, hydraulic cylinder 15 is activated, pushing support plate 12 upward and rotating support plate 12 upward by 90° to keep cylinder 1 vertical.

[0031] Preferably, to accommodate cylinders 1 of different lengths, a set of support seats 14 are provided at intervals. At the same time, to prevent the hydraulic cylinder 15 from pushing the support plate 12 upward by 90°, and to ensure that the cylinder 1 remains vertical after flipping, a support strip 131 is provided on the side of the support plate 13 away from the support seat 14. The thickness of the support strip 131 is consistent with the height difference between the bottom of the support plate 13 and the top surface of the base 11 after the support plate 13 is flipped by 90°, so as to ensure that the support plate 13 remains horizontal after flipping, thereby ensuring the verticality of the cylinder after flipping by 90°. To avoid rigid contact between the support strip 131 and the base 11, a buffer pad 132 is provided on one side of the support strip 131.

[0032] More specifically, in order to increase the friction between the limiting plate 23 and the cylinder 1, the inner wall of the limiting plate 23 is provided with a rubber pad 231.

[0033] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
