[0036] Embodiment 2

[0037] Furthermore, as a specific implementation of the utility model, the utility model provides a quick assembly tool for an electric push rod cylinder.

[0038] On the basis of embodiment 1, in order to facilitate limiting the moving direction of the double-sided rack 202, a limiting rod 5 is inserted into the bottom of the double-sided rack 202, and the bottom end of the limiting rod 5 is connected to the inner bottom wall of the box body 201. A guide groove 6 compatible with the limiting rod 5 is opened at the bottom of the double-sided rack 202, and a through hole 7 for the limiting rod 5 to pass through is opened on the mounting plate 4. By setting the limiting rod 5 and cooperating with the guide groove 6 and the through hole 7, the movement of the double-sided rack 202 is limited and guided to ensure that the double-sided rack 202 can only move up and down.

[0041] Working principle:

[0042] When in use, after the inner cylinder and the outer cylinder of the electric push rod cylinder are placed on the assembly table 1, the assembly table 1 will be driven downward due to the action of gravity, and the double-sided rack 202 will drive the two spur gears 203 to rotate following the movement of the assembly table 1, so that the two L-shaped rods 204 in the open state are close to each other and push the two push plates 205 close to each other respectively, so that the inner cylinder is pushed into the outer cylinder through the two push plates 205. The operation is convenient and fast during the process, which is convenient for rapid assembly of the electric push rod cylinder without providing additional driving force, so the cost is low, it is more environmentally friendly and energy-saving, and the inner cylinder and the outer cylinder are both heavy. At the same time, the outer wall of the inner cylinder and the inner wall of the outer cylinder are coated with lubricating oil during production, so the action of gravity is sufficient to assemble the two together. After the assembly is completed, the assembly table 1 is lifted upward until the upper ends of the inner cylinder and the outer cylinder are exposed from between the two push plates 205. At this time, force can be applied to take out the assembled inner cylinder and outer cylinder.

[0043] The mounting plate 4 facilitates the installation of the reset spring 3 on the bottom of the double-sided rack 202. By setting the initial state, the double-sided rack 202 is kept away from the reset spring 3 on the inner bottom wall of the box body 201. This facilitates the assembly of the workpiece to be processed in the table 1, thereby avoiding the L-shaped rod 204 from limiting the push plate 205 and affecting the next rapid assembly of the electric push rod cylinder. By setting the limit rod 5 and cooperating with the guide groove 6 and the through hole 7, the movement of the double-sided rack 202 is limited and guided to ensure that the double-sided rack 202 can only move up and down, thereby ensuring the assembly effect.
