DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 2 As shown, the compression spring assembly device of the utility model comprises a spring assembly seat 81 and a compression mechanism 82 for compressing the spring; the spring assembly seat 81 is provided with a spring assembly groove 811 for accommodating the spring, the spring assembly seat 81 is provided with a cover plate 812 covering the spring assembly groove 811, the cover plate 812 can be opened and closed on the spring assembly groove 811, and the spring assembly seat 81 is provided with a locking mechanism 814 for locking the cover plate 812 to cover the spring assembly groove 811; the compression mechanism 82 is arranged at one end of the spring assembly seat 81 along the extension direction of the spring assembly groove 811, so as to be able to compress the spring in the spring assembly groove along the extension direction of the spring assembly groove 811, the other end of the spring assembly seat 81 is provided with a spring limiting plate 813 to prevent the spring from moving out of the other end of the spring assembly groove when the spring is compressed, and the spring limiting plate 813 is provided with a through hole 8131 for assembling a spacing nut arranged along the extension direction of the spring assembly groove 811. It can be understood that the inner diameter of the through hole 8131 should be larger than the outer diameter of the distance nut and smaller than the diameter of the spring washer.

[0024] Take the spring device assembly in the drum gear shaft of the hot rolling mill as an example to illustrate. Figure 3 As shown, during assembly, firstly, the second spring pad 5, the second spring 3, the first spring pad 4 and the first spring 2 are sleeved on the guide rod 1, and then the cover plate 812 is opened to install the guide rod into the spring assembly groove 811. When the guide rod is installed, one end of the guide rod installation distance nut 6 extends into the through hole 8131. After the guide rod is installed, the cover plate is finally closed, and the cover plate is locked by the locking mechanism, and then the other end of the guide rod is pushed by the compression mechanism 82, so that the guide rod moves along the spring assembly groove 811 to compress the spring. In the process of compressing the spring, the spring limit plate 813 cooperates with the second spring pad to prevent the second spring pad and the spring from passing through the through hole. When the spring is compressed into place, the distance nut is installed on the guide rod from the through hole, and finally the cover plate is opened, and the guide rod is taken out to complete the assembly.

[0025] The compression spring assembly device of the utility model is provided with a spring assembly groove 811 and a cover plate 812 which can cover the spring assembly groove 811 on the spring assembly seat 81. The spring is assembled in the spring assembly groove 811. The spring assembly groove 811 can restrain the spring to prevent the spring from tilting and breaking off and injuring people. The spring assembly is more convenient and safe, and the assembly efficiency and assembly quality of the spring are improved.

[0026] In the embodiment of the utility model, the cover plate 812 can be opened and closed on the spring assembly groove 811 through a hinge shaft 815 rotatably connected to the spring assembly seat 81. Of course, the cover plate 812 can also be directly buckled on the spring assembly groove 811.

[0027] The diameter of the spacer nut and spring washer is generally matched with the outer diameter of the spring. When the diameter of the spring changes, the diameter of the spacer nut and spring washer will also change. Figure 4 As shown, in order to facilitate the installation of springs of different diameters, the through hole 8131 in the utility model is formed by the inner cavity of the sleeve 816 embedded in the spring stop plate 813. In this way, the size of the through hole 8131 can be changed by replacing the sleeve 816 of the corresponding inner diameter as needed, so that the spring of the corresponding diameter can be installed. The sleeve is replaceable and easy to replace and install, which can improve the efficiency and quality of spring assembly.

[0028] In order to better limit the spring during assembly and prevent elastic deflection, the utility model provides a pressing block 817 in the spring assembly groove 811 that slides with the spring assembly groove 811. One end of the pressing block 817 is provided with a positioning portion 8171 for matching with the end of the guide rod 1, and the other end is connected to the compression mechanism 82. The positioning portion 8171 can be a boss that can be inserted into one end of the guide rod 1 (see Figure 5 ), of course, the positioning portion can also be a boss set on the pressing block 817, and a positioning groove is provided on the boss with an inner diameter that matches the outer diameter of the guide rod 1. After the pressing block is set, the compression mechanism 82 pushes the guide rod to move along the spring assembly groove 811 through the pressing block. Since the pressing block and the spring assembly groove 811 are slidably matched, the pressing block can better ensure that the guide rod and the compression spring will not be skewed when the spring is compressed, and the assembly efficiency and assembly quality of the spring can be better guaranteed.

[0029] The pressing block can be connected to the compression mechanism by bolt connection, welding, plug-in connection, etc. Since the guide rod diameters of springs with different diameters are also different, the positioning portion 8171 of the pressing block 817 will also be different accordingly. In order to facilitate the replacement of the pressing block of the corresponding size positioning portion 8171 according to the guide rod diameter, preferably, the pressing block 817 is sleeved on one end of the compression mechanism 82. That is, the compression mechanism 82 and the pressing block 817 are plug-in connected. In this way, it is more convenient to replace the pressing block 817, and the assembly efficiency of the spring can be better guaranteed.

[0030] The locking mechanism can adopt various existing locking mechanisms, such as: latch locking, screw locking, etc. In the embodiment of the utility model, Figure 6As shown, the cover plate 812 is provided with a locking bayonet 8121, and the locking mechanism includes a pull rod 8141 whose one end can be inserted into the bayonet 8121 and a clamping nut 8142 for fixing the pull rod 8141 in the bayonet 8121, and the other end of the pull rod 8141 is hinged to the spring assembly seat 81 so that the pull rod 8141 can be rotated in the direction close to the bayonet 8121 and inserted into the bayonet 8121, and the clamping nut 8142 is sleeved on the pull rod 8141 and threadedly connected to the pull rod 8141. Thus, when locking, the rod 8141 is rotated to make one end of the rod 8141 snap into the bayonet 8121, and then the compression nut 8142 is screwed to make the compression nut 8142 press on the bayonet 8121, thereby fixing the rod 8141 in the bayonet 8121 and locking the cover 812 on the spring assembly groove 811. When the cover needs to be opened, the compression nut 8142 is screwed to make the compression nut 8142 disengage from the bayonet 8121, and then the rod 8141 can be rotated to move the rod 8141 out of the bayonet 8121. In this way, the cover can be opened.

[0031] The compression mechanism 82 can be a gas cylinder, a hydraulic cylinder, an electric push rod, etc. In the present invention, the compression mechanism 82 is a hydraulic cylinder.
