Description

Technical Field

[0001] The utility model belongs to the technical field of spring linkages, and particularly relates to a spring linkage safety auxiliary device. Background Technique

[0002] A spring linkage is a common mechanical connection element, usually composed of a spring and a connecting rod. In a mechanical structure, the spring linkage is mainly used to transmit force, buffer vibration or serve as a connecting device. The spring linkage usually has a certain elasticity and can deform and produce elastic deformation when subjected to an external force, so as to play roles such as shock absorption, buffering reduction, and force transmission. When installing a spring linkage, it is necessary to first compress the spring. After the spring is compressed, the connecting rod can be fixedly installed at the top of the spring backing plate.

[0003] The existing method of installing a spring linkage is very dangerous and inefficient. Existing methods often use a jack on a gantry without protection measures to compress the spring. After the spring is compressed, there are no protection means and measures, resulting in the spring being prone to pop out and cause injury. There have been many cases of the spring flying off, with a great safety risk. Or use a method of pressing the cover with three screw rods for compression. This method is purely manual and time-consuming and laborious. The time required to assemble a set of spring linkages is very long, and the physical energy consumption of personnel is large, which can no longer meet the needs of actual production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a spring linkage safety auxiliary device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A spring linkage safety auxiliary device, comprising:

[0007] A compression device bottom plate;

[0008] A compression device main frame, which is fixedly connected to the top of the compression device bottom plate;

[0009] An extension mechanism, which is installed on the top of the compression device bottom plate. The extension mechanism includes an extension cylinder, an extension seat and a limit plate. The extension cylinder is fixedly connected to the top of the compression device bottom plate, and the output end of the extension cylinder is fixedly connected with an extension seat, and a limit plate is fixedly connected to the top of the extension seat.

[0010] Preferably, the extension cylinder is fixedly connected to the top of the compression device bottom plate by screws, and the limit plate is inserted into the interior of the compression device main frame.

[0011] Preferably, a plurality of limiting pulleys are arranged outside the limiting plate, a spring connecting rod member is inserted at the top end of the limiting plate, and an opening mechanism is installed at the top end of the main frame of the compression device.

[0012] Preferably, the opening mechanism includes a sliding plate, a limiting block and an upper cushion plate. The sliding plate is fixedly connected to the inner side wall of the main frame of the compression device. A limiting block is fixedly connected to the outside of one side of the sliding plate. The upper cushion plate is inserted at the top end of the sliding plate, and a butting block is fixedly connected to the bottom end of the upper cushion plate.

[0013] Preferably, the upper cushion plate is slidably connected inside the sliding plate. The butting block abuts against the outside of the limiting block, and the bottom end of the upper cushion plate abuts against the top end of the spring connecting rod member.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By arranging the jacking cylinder, the jacking seat, the sliding plate and the limiting block, when installing the spring connecting rod, first stretch and open the upper cushion plate, then place the spring and the connecting rod on the top end of the limiting plate, next close the upper cushion plate, start the jacking cylinder, jack the limiting plate, so that the spring is compressed, thereby enabling the connecting rod inside the spring to be installed on the spring cushion plate. This not only increases the safety during installation but also improves the installation efficiency. Moreover, by replacing the upper cushion plate, it is possible to compress spring connecting rods with different diameters or medium and large-sized vehicle shock absorbers.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1:

[0022] Please refer to Figures 1 - 3 as shown, the spring link safety auxiliary device includes:

[0023] Compression device bottom plate 1;

[0024] The main frame 2 of the compression device is fixedly connected to the top end of the compression device bottom plate 1;

[0025] The top extension mechanism 3 is installed at the top end of the compression device bottom plate 1. The top extension mechanism 3 includes a top extension cylinder 301, a top extension seat 302, and a limit plate 303. The top extension cylinder 301 is fixedly connected to the top end of the compression device bottom plate 1. The output end of the top extension cylinder 301 is fixedly connected to the top extension seat 302. The top end of the top extension seat 302 is fixedly connected to the limit plate 303. The top extension cylinder 301 is fixedly connected to the top end of the compression device bottom plate 1 by screws. The limit plate 303 is inserted into the inside of the main frame 2 of the compression device.

[0026] Specifically, after the top extension cylinder 301 works, it performs a top extension operation on the top extension seat 302, thereby performing an extrusion operation on the spring link member 5 placed on the limit plate 303 to install the spring link member 5. When the limit plate 303 performs a top extension movement, the limit pulley 4 performs a limit rolling operation outside the main frame 2 of the compression device, thereby increasing the stability of the limit plate 303 during movement.

[0027] As can be seen from the above, when installing the spring link, first, the upper backing plate 603 is stretched and opened, the spring and the link are placed on the top of the limit plate 303, and then the upper backing plate 603 is closed. At this time, the top extension cylinder 301 works to perform a top extension operation on the limit plate 303, so that the spring is compressed by extrusion, and the link inside the spring can be installed on the spring backing plate, thereby increasing the safety during the installation of the spring link and also improving the installation efficiency.

[0028] Embodiment 2:

[0029] Refer to Figure 1 and Figure 3As shown in the figure, a plurality of limiting pulleys 4 are arranged outside the limiting plate 303. A spring link member 5 is inserted into the top end of the limiting plate 303. An opening mechanism 6 is installed at the top end of the main frame 2 of the compression device. The opening mechanism 6 includes a sliding plate 601, a limiting block 602, and an upper backing plate 603. The sliding plate 601 is fixedly connected to the inner side wall of the main frame 2 of the compression device. A limiting block 602 is fixedly connected to the outside of one side of the sliding plate 601. The upper backing plate 603 is inserted into the top end of the sliding plate 601. A butting block 604 is fixedly connected to the bottom end of the upper backing plate 603. The upper backing plate 603 is slidably connected inside the sliding plate 601. The butting block 604 abuts against the outside of the limiting block 602. The bottom end of the upper backing plate 603 abuts against the top end of the spring link member 5.

[0030] As can be seen from the above, when the upper backing plate 603 is pulled out, the spring link member 5 can be stably inserted and placed inside the limiting plate 303, thereby facilitating the placement of the spring link member 5 and increasing the stability of the spring link member 5 during extrusion installation. Moreover, the butting block 604 abuts against the outside of the limiting block 602, which can limit the movement of the upper backing plate 603.
