[0038] In combination with Figure 1 and Figure 2The spring mounting device 100 can be used for automatic assembly of the spring 10, realizes picking up the spring 10 and hitting into the target mounting hole 200, and completes the installation of the spring 10. In the embodiment, the spring 10 installation in the compressor assembly process is taken as an example, and the spring 10 is installed into the spring 10 mounting hole of the cylinder. Of course, it is not limited to this, and the spring mounting device 100 can also be applied to other occasions requiring spring 10 assembly, so as to improve the installation efficiency and installation yield.

[0039] The spring mounting device 100 comprises a rotating rod 110, an elastic member 120 and a mounting elbow 130. The elastic member 120 is installed on the rotating rod 110 and is used for picking up the spring 10. The spring 10 comprises a guide part 11 and a mounting part 12 connected with each other, and the diameter L2 of the guide part 11 is greater than the diameter L1 of the mounting part 12. The mounting elbow 130 is arranged on the rotating rod 110 and is used for abutting against the spring 10. Since the elastic member 120 is arranged on the rotating rod 110, the circumferential size of the rotating rod 110 can be conveniently changed, so that the rotating rod 110 and the spring 10 are better matched, the spring 10 is conveniently and reliably picked up, and the spring 10 is not easy to fall off. Through the arrangement of the mounting elbow 130, the mounting elbow 130 abuts against the spring 10 to continuously apply force to the spring 10 during the spring 10 press-fitting process, so that the spring 10 is conveniently hit into the mounting hole, and the installation efficiency and assembly yield are improved.

[0040] In combination Figure 3 Optionally, the rotating rod 110 comprises a picking-up part 111, an elbow fixing part 112 and a transmission part 113 connected in sequence. The elastic member 120 is arranged on the outer periphery of the rotating rod 110, and specifically, the elastic member 120 is installed on the picking-up part 111. The elastic member 120 is used for changing the circumferential size of the rotating rod 110; the circumferential size D of the rotating rod 110 is greater than the diameter L1 of the mounting part 12 and is less than the diameter L2 of the guide part 11. In other words, the spring 10 has relatively large and small ends. The mounting part 12 belongs to the small end, and the guide part 11 belongs to the large end.

[0041] When the picking-up part 111 picks up the spring 10, one end of the guide part 11 of the spring 10 is inserted and can be partially inserted into the mounting part 12. The rotating rod 110 is in interference fit with the mounting part 12, so that the spring 10 is prevented from falling off during the process of picking up the spring 10 and moving after picking up the spring 10. The arrangement of the elastic member 120 not only facilitates the insertion into the large end of the spring 10, but also realizes the interference fit with the small end, and the structure is reliable.

[0042] Optionally, the elastic member 120 is made of a metal wire, such as a deformed steel wire or the like. The elastic member 120 can be in a sheet shape, a strip shape, or a rod shape, i.e., the cross-sectional shape of the elastic member 120 can be flexibly set according to actual conditions, including but not limited to a circular shape, a semicircular shape, an elliptical shape, a crescent shape, an arch shape, a triangular shape, a quadrilateral shape, a pentagonal shape, a hexagonal shape, or any polygonal shape, which is not specifically limited here. The material of the elastic member 120 can be metal or non-metal, such as plastic, rubber, or other materials, etc. In this embodiment, the elastic member 120 is made of an elastic steel wire. In this way, when inserted into the spring 10, the overall circumferential dimension of the rotating rod 110 and the elastic member 120 is reduced under the action of an external force, facilitating insertion into the mounting portion 12 of the spring 10. After the external force is removed, due to the restoring force of the elastic member 120, the elastic member 120 and the mounting portion 12 are favorably provided with an interference fit, thereby preventing the spring 10 from falling out of the rotating rod 110.

[0043] One end of the elastic member 120 is connected to the pickup portion 111, and the other end extends in an axial direction away from the elbow fixing portion 112, extending to the peripheral side surface of the pickup portion 111, or extending to the end surface of the pickup portion 111 away from the elbow fixing portion 112. The extension length of the elastic member 120 is not specifically limited, and the extension direction can be linear extension or winding in the circumferential direction of the rotating rod 110, extending in a spiral shape. One end of the elastic member 120 is connected to the pickup portion 111, and the connection method can be clamping, sleeving, inserting, bonding, riveting, or welding, etc., which is not specifically limited here.

[0044] In combination Figure 4 and Figure 5 Optionally, the mounting elbow 130 is sleeved on the rotating rod 110 and holds the elastic member 120. In this embodiment, the elbow fixing portion 112 of the rotating rod 110 is used to arrange the mounting elbow 130. That is, the mounting elbow 130 is sleeved on the elbow fixing portion 112. The mounting elbow 130 partially holds the elastic member 120 to limit the elastic member 120, and further fix the elastic member 120 on the rotating rod 110.

[0045] Optionally, the axis of the mounting elbow 130 is arranged at an angle with the axis of the rotating rod 110. That is, the mounting elbow 130 is designed as an eccentric structure. The angle B can be 5 degrees to 40 degrees, such as 5 degrees, 8 degrees, 10 degrees, 12 degrees, 15 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 26 degrees, 28 degrees, 30 degrees, 35 degrees, or any value between 5 degrees and 40 degrees. The eccentric arrangement makes the spring 10 more efficient and labor-saving when installed into the target mounting hole 200, and the assembly consistency is better, improving the assembly yield of the spring 10.

[0046] Optionally, the mounting elbow 130 is provided with a first mounting hole 131 and a second mounting hole 132. The axis of the first mounting hole 131 forms an angle of 5-40 degrees with the axis of the rotating rod 110, and the first mounting hole 131 is arranged to be sleeved on the rotating rod 110. The shape and size of the first mounting hole 131 are adapted to the shape and size of the elbow fixing portion 112, respectively.

[0047] The second mounting hole 132 is used for the fixing member 140 to pass through, so as to fix the mounting elbow 130 on the rotating rod 110. In the embodiment, the axis of the second mounting hole 132 is substantially perpendicular to the axis of the rotating rod 110, or forms an angle of 60-80 degrees. The fixing member 140 includes but is not limited to a bolt, a pin shaft, etc.

[0048] Optionally, the mounting elbow 130 has an arc surface 133 for abutting against the spring 10. In the embodiment, the mounting elbow 130 is designed to be substantially hemispherical, i.e., has a spherical arc surface 133 abutting against the spring 10.

[0049] Optionally, the transmission portion 113 of the rotating rod 110 is used to be connected with an external power source. The external power source can be a driving member such as a motor or a cylinder, etc. The driving member is in driving connection with the transmission portion 113, and can drive the transmission portion 113 to rotate, so as to realize the rotation of the entire rotating rod 110 and the mounting elbow 130 along the axis of the rotating rod 110. Of course, the driving member can realize the movement or rotation of the rotating rod 110, or the movement and rotation at the same time. The number of the driving members is not limited, for example, two, one for realizing the movement of the rotating rod 110, and the other for realizing the rotation of the rotating rod 110.

[0050] When the spring 10 is pressed into the target mounting hole 200, the target mounting hole 200 in the embodiment is a spring 10 mounting hole of a cylinder of a compressor. The rotating rod 110 is rotated, so that the mounting elbow 130 and the rotating rod 110 are rotated together. Since the mounting elbow 130 is designed to be eccentric, during the rotation, the mounting elbow 130 applies pressure along the circumference of the spring 10 in turn, so that the spring 10 is gradually pressed into the target mounting hole 200. Since only a part or one side of the spring 10 is subjected to force at each moment during the pressing, the spring 10 is more easily pressed into the target mounting hole 200, and the required spring 10 pressing force is smaller. Moreover, during the rotation of the mounting elbow 130, the force applied to the spring 10 in turn is uniform in size in the circumferential direction, and the assembly consistency is good, which is beneficial to improve the assembly yield.

[0051] The utility model embodiment further provides a spring assembly equipment, including spring arrangement device and preceding spring mounting device 100, spring arrangement device is used for to spring 10 carries out early stage arrangement, such as to spring 10 carries out dispersion and position, namely separates spring 10 to single, and according to certain installation direction will single spring 10 in turn deposit to the installation area of waiting. Spring mounting device 100 is used to pick up the spring 10 after the arrangement of spring arrangement device, namely rotating lever 110 picks up spring 10 from the installation area of waiting, and through installation elbow 130 installs spring 10 into target installation hole 200. This is favorable to realize the automation installation of spring 10, improves the assembly efficiency and assembly yield of spring 10.

[0052] In combination Figures 6 to 10 In the embodiment, the installation method of spring 10 is as follows:

[0053] Rotating lever 110 picks up spring 10. Rotating lever 110 moves to spring 10, and stretches into and penetrates to installation part 12 of spring 10 from guide part 11 of spring 10. Due to the effect of elastic member 120, rotating lever 110 and installation part 12 are interference fit, which can prevent spring 10 from falling.

[0054] Rotating lever 110 is moved to make spring 10 align target installation hole 200. After the picking up of spring 10 is completed, rotating lever 110, installation elbow 130 and spring 10 move as a whole, rotating lever 110 drives spring 10 to move to target installation hole 200, and spring 10 aligns target installation hole 200. In the above picking up and aligning target installation hole 200 process, rotating lever 110 only moves, without rotating.

[0055] Spring 10 enters the press-fitting stage. Rotating lever 110 is rotated and moved, and rotating lever 110 rotates while moving towards target installation hole 200. Among them, installation elbow 130 realizes eccentric rotation under the rotating action of rotating lever 110, so as to press-fit spring 10 into target installation hole 200, and complete the press-fitting of spring 10. In the process, rotating lever 110 moves and rotates. Optionally, rotating lever 110 needs to rotate for about two to four seconds each time.

[0056] Then, rotating lever 110 exits from target installation hole 200. In the exit process, rotating lever 110 only moves, without rotating.

[0057] It should be noted that the hole diameter of the target mounting hole 200 is greater than the diameter of the mounting portion 12 and less than the diameter of the guide portion 11. When the mounting knob 130 is pressed into the spring 10, the entire spring 10 is pressed into the target mounting hole 200, that is, the guide portion 11 and the mounting portion 12 are both pressed into the target mounting hole 200. In this way, the spring 10 and the target mounting hole 200 achieve an interference fit, and the clamping force between the two is greater than the clamping force between the rotating rod 110 and the spring 10. Therefore, the rotating rod 110 can be withdrawn from the target mounting hole 200 under the action of an external force without taking out the spring 10.

[0058] In summary, the spring mounting device 100 and the spring assembly equipment provided by the embodiments of the present application have the following beneficial effects, including:

[0059] The elastic member 120 is arranged on the rotating rod 110, which facilitates changing the circumferential size of the rotating rod 110, so that the rotating rod 110 and the spring 10 are better matched, the spring 10 is easily picked up and reliably, and is not easy to fall off. By arranging the mounting knob 130, the mounting knob 130 is designed as an eccentric structure, and in the spring 10 pressing process, the mounting knob 130 rotates eccentrically and abuts against the spring 10 to continuously apply force to different parts of the spring 10, so as to facilitate the spring 10 to be driven into the target mounting hole 200, and improve the installation efficiency and assembly yield.

[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; any modification, equivalent replacement, improvement, etc. should be included in the protection scope of the present application.
