Description

Technical Field

[0001] The utility model relates to the field of cylinder fixing equipment, in particular to a chain type cylinder fixer. Background Art

[0002] The cylinder mechanism mainly includes a sleeve and a bracket. The sleeve is installed inside the two brackets. The sleeve is hollow. When processing the sleeve, it is necessary to bore or polish the inner wall of the sleeve. During the polishing process of the sleeve, in order to ensure the processing accuracy and stability, a special fixture is required to clamp and fix the cylinder.

[0003] For related technologies, reference may be made to the Chinese patent with announcement number CN219987557U, which discloses a fixed support for assembling a hydraulic cylinder, including a workbench, a base is arranged on the workbench, a circular groove is opened at the upper end of the base, a turntable is movably arranged in the groove, a first clamp and a second clamp are arranged at the upper end of the turntable, a pedestal is arranged on the turntable, a screw is arranged through the threaded hole on the pedestal, and one end of the screw is connected to the second clamp. The cylinder barrel is stably and reliably placed between the first clamping groove and the second clamping groove, and the cylinder barrel is limited and supported by the first clamping groove and the second clamping groove. The cylinder barrel is easy to put into the first clamping groove and the second clamping groove, and will not be separated from the first clamping groove and the second clamping groove. The second clamp is pushed to move to one side of the center of the turntable by rotating the screw, and then the cylinder barrel is clamped by the first clamp and the second clamp, which is convenient to operate, safe and reliable.

[0004] With respect to the above-mentioned related technologies, when clamping the cylinder, the cylinder needs to be placed between the first clamping groove and the second clamping groove, but the sizes of different cylinders are also different. When the outer diameter of the cylinder is not compatible with the inner diameters of the first clamping groove and the second clamping groove, for example, when the diameter of the cylinder is smaller than the diameters of the first clamping groove and the second clamping groove, the contact area between the cylinder and the first clamp and the second clamp is small. After the first clamp and the second clamp cooperate to clamp the cylinder, the cylinder is prone to shaking, so it is inconvenient to fix cylinders with different structures. Utility Model Content

The threaded ring 441 is located at the end of the positioning block 45 away from the mounting seat 2, and the threaded ring 441 is rotatably connected to the positioning block 45. The positioning block 45 limits the threaded ring 441, so that when the threaded ring 441 rotates, it drives the positioning rod 43 to move along the axial direction.

[0040] refer to Figure 1 and Figure 2 , the driving handle 442 is located on the side of the threaded ring 441 away from the positioning rod 43, and is fixedly connected to the threaded ring 441. When the driving handle 442 rotates, the threaded ring 441 can be driven to rotate synchronously. The driving handle 442 is convenient for the operator to hold to improve the convenience of rotating the threaded ring 441. In other embodiments, an electric drive assembly can also be selected to replace the manual drive method. Specifically, the electric drive assembly includes a motor and a lead screw. The motor adopts a DC motor to ensure sufficient driving capacity. The lead screw adopts a cylindrical structure, and the lead screw is connected to the motor through a coupling to ensure the stability and stability of the transmission. The lead screw is driven to rotate by the motor, the lead screw is threaded with the positioning block 45, and the lead screw is rotatably connected to one end of the positioning rod 43 away from the mounting seat 2. Under the support of the positioning block 45, the positioning rod 43 is pushed to move when the lead screw rotates.

[0043] refer to Figure 1 and Figure 2 All the chain links 31 are provided with arc surfaces 311 adapted to the top column 432 on both sides along the hinge direction. When the positioning rod 43 pushes the top column 432 to approach the fixed chain 3, the top column 432 enters the arc surface 311 and contacts the arc surface 311. At this time, the positioning rod 43 is continuously moved toward the mounting seat 2, so that the top column 432 pushes the fixed chain 3 to deform, thereby continuously tightening the fixed chain 3, further improving the clamping stability of the fixed chain 3 on the cylinder.

[0044] The implementation principle of a chain-type cylinder barrel fixer in the embodiment of the present application is as follows: the base 1 is used to place the sleeve, and one end of the fixed chain 3 is positioned through the mounting seat 2. When the fixed chain 3 is placed away from the fixing column 312 of the mounting seat 2 into the slot 421, the support block 42 is limited by the matching of the slot 421 and the fixing column 312 and the other end of the fixed chain 3. The cylinder barrel is located between the fixed chain 3 and the base 1. At this time, the fixed chain 3 is attached to the cylinder barrel and the cylinder barrel is initially limited. The threaded ring 441 is rotated so that the threaded ring 441 pushes the positioning rod 43 and the top column 432 to approach the fixed chain 3. After the top column 432 contacts the arc surface 311 of the corresponding chain ring 31, it pushes the fixed chain 3 to deform, thereby continuously tightening the fixed chain 3 to improve the clamping stability of the cylinder barrel. The shape of the fixed chain 3 during positioning is set according to the cylinder barrel, and is thus suitable for cylinder barrels of different shapes, which is conducive to improving the convenience of fixing different cylinder bodies.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
