[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] See appendix Figure 1 To be continued Figure 3 As shown, this embodiment provides a spring pressing device 10, including a frame 100, a feeding clamp 300, a pressing cylinder assembly 400, a spring pressing cylinder 500, and a spring pressing cylinder head 600.

[0037] See attached document Figure 4 As shown, in this embodiment, the spring-loaded pressing cylinder head 600 includes a cylinder head body 601. One front end of the cylinder head body 601 has an upper pressing surface 602 for pressing the upper end of the spring 30 and a lower pressing surface 603 for pressing the lower end of the spring 30. The front end of the cylinder head body 601 is the side that contacts and presses against the spring 30. Furthermore, the bottom end of the lower pressing surface 603 on the cylinder head body 601 also has an outwardly protruding protrusion 604, which is used to push the spring 30 into an arc shape.

[0038] See attached document Figure 4 As shown, specifically, the upper pressing surface 602 of the cylinder head body 601 is a downward inclined surface, the lower pressing surface 603 of the cylinder head body 601 is a vertical planar structure, and the protrusion 604 is an arc-shaped external structure.

[0039] Combined with reference to the appendix Figure 4 and attached Figure 5As shown, by adopting this type of spring-loaded pressing cylinder head 600, during the process of pressing the spring 30, the protrusion 604 on the spring-loaded pressing cylinder head 600 first presses and contacts the spring 30, and the protrusion 604 pushes the spring 30 into an arc shape, so that the spring 30 fits between the bottom frame and the cover frame of the advertising frame. At the same time, the upper pressing surface 602 and the lower pressing surface 603 press the upper end and the lower end of the spring 30 respectively, realizing the pressing and positioning of the spring 30. It simultaneously performs the two functions of pressing, installing and positioning the spring 30. Therefore, its structure is simpler, the cost is reduced, and the installation steps of the spring 30 are simpler, and the production cycle is shortened.

[0040] Continue to refer to the appendix Figure 4 and attached Figure 5 As shown, the bottom end of one side of the cylinder head body 601 also has a bottom pressing slope 605 for pressing the bottom frame. In this way, when the cylinder head body 601 presses the spring 30 onto the part to be installed 20 (cover frame and bottom frame), the bottom pressing slope 605 will apply a downward force to the bottom frame to prevent the bottom frame from shaking.

[0041] See attached document Figure 1 and attached Figure 2 As shown, the material feeding clamp 300 is fixedly installed on the top of the frame 100 by the base 200 installed at the bottom. The material feeding clamp 300 has a groove 301, which is used to place the part to be installed 20.

[0042] The pressing cylinder assembly 400 is fixedly installed on the top of the frame 100. The pressing cylinder assembly 400 is used to press the workpiece 20 to be installed into the unloading clamp 300. Specifically, the pressing cylinder assembly 400 includes an arc-shaped cylinder fixing bracket 401, a pressing cylinder 402, and a pressing cylinder head 403. One end of the arc-shaped cylinder fixing bracket 401 is fixedly installed on the top side of the base 200, and the other end extends to the upper side of the groove 301 in the unloading clamp 300. The pressing cylinder 402 is fixedly installed on one side of the other end of the arc-shaped cylinder fixing bracket 401, and the pressing cylinder head 403 is fixedly installed on the piston rod of the pressing cylinder 402.

[0043] Thus, after the part to be installed 20 is placed in the groove 301 in the feeding fixture 300, the piston rod of the pressing cylinder 402 extends outward, driving the pressing cylinder head 403 to move closer to one side of the groove 301, so as to press the part to be installed 20 into the groove 301 in the feeding fixture 300.

[0044] Continue to refer to the appendix Figure 1 and attached Figure 2As shown, the spring pressing cylinder 500 is connected to the spring pressing cylinder head 600. The spring pressing cylinder 500 is fixedly installed on the other side of the other end of the bow-shaped cylinder fixing frame 401. That is, the spring pressing cylinder 500 and the pressing cylinder 402 are respectively set on opposite sides of the bow-shaped cylinder fixing frame 401. The parallel arrangement of the two makes the whole structure more compact. In addition, after the pressing cylinder 402 drives the pressing cylinder head 403 to press and fix the part to be installed 20 in the groove 301 in the feeding jig 300, the part to be installed 20 will not shake when the spring is installed on it. The spring pressing cylinder 500 then drives the spring pressing cylinder head 600 to extend outward, pressing and positioning the spring in the part to be installed 20. The entire spring installation process is simpler and the production cycle is shortened.
