Description

Technical Field

[0001] The utility model relates to the technical field of the spare part assembly mechanism of a socket, and particularly relates to a torsion spring screw feeding and assembling device for a socket bottom shell. Background Art

[0002] A socket, also known as a power socket or a switch socket, is a household electrical appliance device installed on a wall. As Figure 1 shown, Figure 1 it is the socket bottom shell 6 (the socket bottom shell is a semi-finished product of the socket) inside the socket. Among them, both ends of the socket bottom shell 6 are provided with iron hook pieces. One side wall of the iron hook piece is used for installing a torsion spring 7, and the top of the iron hook piece is used for installing a screw 8. The installation sequence of the above torsion spring 7 and screw 8 is as follows: Please refer to Figure 2 , first insert the torsion spring 7 into the side wall of the iron hook piece, then pass the screw 8 through the top of the iron hook piece and the middle of the torsion spring 7 in sequence, and then tighten it with the thread on the socket bottom shell 6.

[0003] Due to the complex shape properties of the iron hook pieces of the socket bottom shell 6, it is difficult to install the torsion spring 7 and the screw 8. The current practices in the industrial field are as follows:

[0004] 1. It is completed semi-automatically. The socket bottom shell 6 is assembled into the fixture body 1 and conveyed to the manual assembly position. The torsion spring 7 and the screw 8 are manually placed in sequence, and then the screw 8 is tightened, and then conveyed to the next working station. However, it has the disadvantage of low production efficiency.

[0005] 2. It is completed through two automated working stations. The feeding and assembling of the torsion spring 7 and the screw 8 are completed through two working stations. However, it also has the characteristic of low production efficiency. Moreover, during the process of transporting from the torsion spring 7 assembling station to the screw 8 assembling station, an additional tightening mechanism is required to tighten the torsion spring 7 to prevent the torsion spring 7 from running out or the position of the torsion spring 7 from changing during transportation, so as to prevent the subsequent assembly from failing. At this time, it has the disadvantage of complex automated assembly. Summary of the Utility Model

[0039] A first buffer 37 is installed below the clamping and pushing component 33 of the torsion spring assembling mechanism 3, and a buffer rubber column 38 is installed above it. The functions of the first buffer 37 and the buffer rubber column 38 are to reduce the impact during the lifting and lowering of the clamping and pushing component 33.

[0040] The structural composition of the screw feeding and assembling mechanism 4 is as follows:

[0041] The second lifting drive module 42 includes a second slide rail and slider assembly 422 and a second lifting cylinder 421 respectively installed on the second machine base 41.

[0045] The operating principle of a torsion spring and screw feeding and assembling device for a socket bottom shell according to an embodiment of the present utility model is as follows:

[0046] S1: The socket bottom shell 6 is placed on the fixture body 1, and the torsion springs 7 are placed in the torsion spring placement grooves 21 of the torsion spring feeding fixtures 2 at both ends of the fixture body 1. Then, the fixture body 1 and the torsion spring feeding fixtures 2 at its both ends are transferred to the installation station between the torsion spring assembly mechanism 3 and the screw feeding and assembly mechanism 4 by a feeding mechanism in the prior art.

[0047] S2: The first lifting cylinder 321 of the first lifting drive module 32 of the torsion spring assembly mechanism 3 drives the clamping and pushing component 33 to descend, so that the insertion posts 333 on the mounting plate 332 of the clamping and pushing component 33 are inserted into the jack blocks 222. Immediately afterwards, the clamping jaws 331 drive the two insertion posts 333 to clamp, so that the two insertion posts 333 respectively drive the jack blocks 222 of the two torsion spring feeding fixtures 2 to move towards each other, thereby causing the pushing plate 221 to slide into the torsion spring placement groove 21 along the pushing port 212, and pushing the torsion spring 7 in the torsion spring placement groove 21 into the feeding port 211 and finally pushing the torsion spring 7 to the bottom of the screw mounting hole 9 at one end of the fixture body 1.

[0048] S3: The second lifting cylinder 421 of the screw feeding and assembly mechanism 4 drives the two screw feeders 43 to descend to the top or directly above the screw mounting holes 9 at both ends of the fixture body 1. The screw feeding channels 431 of the screw feeders 43 are connected to a screw 8 feeding source mechanism in the prior art, so that the screws 8 enter the screw feeding channels 431, and then the screws 8 enter the screw circulation channels 432.

[0049] The top of the screw circulation channel 432 is for the feeding pressure rod 442 to be inserted. Its bottom is semi-circular, and the bottom of the elastic clamping block 433 is also semi-circular. The bottom of the screw circulation channel 432 and the elastic clamping block 433 of the fixture combine to form a circle, and this circle is the screw feeding port 435.

[0050] The third lifting cylinder 441 drives the feeding pressure rod 442 to descend. The feeding pressure rod 442 is inserted into the screw circulation channel 432. The feeding pressure rod 442 presses against the screw 8 and extrudes the screw 8 into the screw feeding port 435 and then into the screw mounting hole 9 of the fixture body 1. (During this extrusion process, the screw feeding port 435 is squeezed and expanded, and the elastic clamping block 433 and the elastic spring 434 are pulled apart.)

[0051] S4: The feeding and assembly of the torsion spring 7 and the screw 8 for the socket bottom shell 6 are completed. The torsion spring assembly mechanism 3 and the screw feeding and assembly mechanism 4 are reset. The fixture body 1 and the torsion spring feeding fixtures 2 at its both ends are removed by a feeding mechanism in the prior art and transferred to the next station for screw tightening.

[0052] A torsion spring screw feeding and assembling device for a socket bottom shell according to an embodiment of the present utility model can successively complete the feeding and assembling of the torsion spring 7 and the screw 8 through one station. The screw 8 can be assembled onto the torsion spring 7 and the socket bottom shell 6 respectively at one station, which can avoid the position change of the torsion spring 7. Its automatic assembling action is simpler and the production efficiency is higher.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
