[0002] At present, the hydraulic cylinders of bending machines on the market are usually fixed with bolts. This fixing method has certain risks. For example, after the machine tool has been used for a long time, the bolts may break, causing the hydraulic cylinder to fall off, posing a safety hazard. Utility Model Content
[0003] The utility model provides a heavy-duty oil cylinder embedded block type fixing mechanism, which can prevent the oil cylinder from falling off due to the loosening, fatigue or breaking of bolts.
[0004] The technical solution of the utility model is as follows:
[0005] A heavy-duty oil cylinder block-type fixing mechanism includes a frame and an oil cylinder assembly fixedly connected to the frame. The frame is provided with a mounting seat for fixing the oil cylinder assembly, including a fixing clamp. A fixing slot is opened on one side of the oil cylinder assembly.
[0006] One end of the fixing clamp is embedded in the fixing slot, and the end of the fixing clamp away from the fixing slot bypasses the mounting seat, and a wedge-shaped insert for clamping the oil cylinder assembly is embedded between the fixing clamp and the mounting seat.
[0007] Furthermore, the vertical projection surface of the fixing clamp is in a “[”-shaped structure.
[0008] Furthermore, an anti-slip groove is provided on the side surface of the fixing clamp, and the anti-slip groove is engaged with the side surface of the mounting seat.
[0009] Furthermore, the wedge-shaped insert is provided with a wedge-shaped surface on the side facing away from the mounting seat, and the inner side of the fixing clamp is provided with an inclined surface that cooperates with the wedge-shaped surface;
[0010] One side of the wedge-shaped insert abuts against the mounting seat, and the wedge-shaped surface abuts against the inclined surface on the inner side of the fixing clamp.
[0011] Furthermore, the fixing clamp is provided with a through hole for the wedge-shaped insert to completely pass through.
[0012] Furthermore, an insert pull plate is provided, which is located on the side of the fixed clamp facing away from the wedge-shaped insert. The insert pull plate is fixedly connected to the wedge-shaped insert through a fastener and the fixed clamp.

DETAILED DESCRIPTION
[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] like Figures 1 to 5 As shown, a heavy-duty cylinder block-type fixing mechanism has a main structure including, but not limited to, a frame 1 and a cylinder assembly 2 fixedly connected to the frame 1. A mounting base 11 for fixing the cylinder assembly 2 is provided on the frame 1, and the cylinder assembly 2 is mounted on the mounting base 11 via fasteners (such as bolts). The mounting base 11 in this embodiment adopts a plate-like structure for easy assembly. It is mounted on the frame 1 and is provided with diagonal reinforcement ribs to ensure structural strength. To improve the reliability of the fixing of the cylinder assembly 2, this embodiment is provided with a fixing clamp 41, and a fixing slot 21 is opened on one side of the cylinder assembly 2 (usually opened in the housing of the cylinder assembly 2).
[0028] Specifically, in this embodiment, the structure of the fixing member 41 is designed to have a "["-shaped structure on the projection surface in the vertical direction, which is convenient for clamping and fixing. Then, one end of the fixing member 41 is embedded in the fixing slot 21, and the end of the fixing member 41 away from the fixing slot 21 bypasses the mounting seat 11. A wedge-shaped insert 42 for clamping the cylinder assembly 2 is embedded between the end of the fixing member 41 away from the fixing slot 21 and the mounting seat 11. Through the lateral clamping force, the cylinder assembly 2 is tightly fitted to the mounting seat 11. At the same time, an anti-slip groove 111 is opened on the side of the fixing member 41. The fixing member 41 is embedded in the mounting seat 11 through the anti-slip groove 111, which is used to limit the fixing member 41 in the vertical direction to prevent it from falling.
[0029] In this embodiment, a wedge-shaped surface 421 is provided on the side of the wedge-shaped insert 42 facing away from the mounting seat 11, and an inclined surface is provided on the inner side of the fixing clamp 41 to mate with the wedge-shaped surface 421. The side of the wedge-shaped insert 42 facing away from the wedge-shaped surface 421 is then brought into contact with the mounting seat 11, with the wedge-shaped surface 421 contacting the inclined surface on the inner side of the fixing clamp 41. The wedge-shaped insert 42 expands the distance between the mounting seat 11 and the end of the fixing clamp 41 away from the fixing slot 21, thereby clamping the cylinder assembly 2.
[0030] In order to reserve space for the wedge-shaped insert 42 to move and embed, in this embodiment, a through hole 44 is opened in the fixing clamp 41 for the wedge-shaped insert 42 to completely pass through.
[0031] In this embodiment, the wedge-shaped insert 42 is tightly nested between the mounting base 11 and the end of the fixing member 41 facing away from the fixing slot 21 by means of the insert plate 45 provided. Specifically, the insert plate 45 is disposed on the side of the fixing member 41 facing away from the wedge-shaped insert 42. The head of the fastener (e.g., a bolt) abuts against the side of the insert plate 45 facing away from the fixing member 41, then passes through the fixing member 41 and securely connects to the wedge-shaped insert 42. The tighter the fastener is tightened, the closer the wedge-shaped insert 42 is nested. Furthermore, because the wedge-shaped insert 42 may undergo lateral displacement during insertion, this embodiment also provides strip-shaped holes 46 on either side of the through-hole 44 to facilitate adjustment of the position of the fastener and the insert plate 45.
[0032] In order to enhance the stability of the fixing member 41 , this embodiment further provides a strip-shaped hole 46 on the side of the fixing member 41 , and the fixing member 41 is fixedly connected to the mounting base 11 by fasteners (such as bolts).
[0033] In addition, this embodiment also includes a fixing block 3. A first positioning slot 22 is defined on the side of the frame 1 facing the cylinder assembly 2. A second positioning slot 12 is defined on the side of the cylinder assembly 2 facing the first positioning slot 22. The fixing block 3 is embedded in both the first and second positioning slots 22 and 12. This block 3 supplements the existing bolts, supporting the cylinder assembly 2 and reducing the load on the bolts connecting the mounting base 11 to the cylinder assembly 2, thereby increasing its service life. The fixing block 3 is preferably a rectangular parallelepiped structure for enhanced stability and structural strength.
[0034] During use of this embodiment, after assembling the components as shown, the cylinder assembly 2 is clamped by tightening the fasteners on the insert pull plate 45, and then the fasteners on the fixing clamp 41 are tightened to complete the assembly. An insert-type fixing structure of the same structure can be symmetrically installed on the other side of a set of cylinder assemblies 2, but this will not be described in detail in this embodiment.
[0035] The design principle of this embodiment is that all bolts must maintain a safe tensile strength range; if they exceed this limit, they will break. If the machine tool lamp is overloaded during use, the bolts securing the oil cylinder could break due to exceeding their maximum tensile strength, posing a dangerous hazard. However, this embodiment effectively absorbs the majority of the load when subjected to significant tensile forces, protecting the bolts from exceeding their ultimate tensile strength. Furthermore, the overall structural rigidity of the oil cylinder's insert-type fixing mechanism is strong, capable of withstanding large, instantaneous impact loads that exceed the tensile load of bolts under equivalent conditions by more than ten times.
[0036] In addition, the overall structure of this embodiment is simple to install and debug, easy to maintain, and low in cost.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
