Description

Technical Field

[0001] The utility model relates to the technical field of elastic pin feeding and pressing, in particular to a novel single-time progressive elastic pin pressing and feeding device. Background Art

[0002] At present, the feeding mechanism of pin parts used is composed of a bird's beak and a push pin, and the elastic pin is directly fed into the press-fit bird's beak; however, the direct connection method will cause multiple elastic pins to mix in, which is easy to cause the bird's beak to be blocked;

[0003] The existing method of detecting elastic pins is a ring sensor, which can only detect whether the product has passed, but cannot detect the location of the product in real time; and it may cause the pressed product to be unqualified. At present, the compressed air released by air blowing will affect the surface of the product and has limitations in use; at the same time, when blockage occurs frequently, the time for repairing and maintaining the feeding mechanism also affects the production efficiency.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-Figure 3 , a new type of single progressive elastic pin press-fit feeding device, comprising:

[0028] Base 16;

[0029] The matching block 14 is fixedly connected to the base 16;

[0030] The slider 3 is slidably connected in the matching block 14;

[0031] The limit block 12 is fixedly connected to the base 16;

[0032] The ejector pin 9 is slidably connected in the limit block 12;

[0033] A pipe joint 2 is fixedly connected to the base 16;

[0034] The feed pipe 1 is fixedly connected to the pipe joint 2.

[0035] The slide block 3 is provided with a material opening which matches the elastic pin.

[0036] It should be noted that the matching block 14 is provided with a beam-receiving optical fiber body 4, which is a beam-receiving optical fiber available on the market, and the model number may be TZLG8-S18-3F1;

[0037] Reference Figure 1 There are multiple groups of opposing optical fiber bodies 4, and the multiple groups of opposing optical fiber bodies 4 are respectively arranged on the matching blocks 14.

[0038] The base 16 is fixedly connected with a mounting plate 15 , the mounting plate 15 is fixedly connected with a cylinder 5 , and a driving end of the cylinder 5 is connected to the slider 3 .

[0039] It should also be noted that the ejector pin 9 is connected to an external press, and the ejector pin 9 is pushed to move by the external press.

[0040] It should be noted that a throttle valve 6 is installed on the cylinder 5, and the throttle valve 6 is a valve available on the market.

[0041] The extension speed of the cylinder 5 can be controlled by the throttle valve 6 provided.

[0042] A positioning bolt 7 is fixedly connected to the driving end of the cylinder 5 , a floating joint 13 is connected to the slider 3 , a nut 8 is fixedly connected to the floating joint 13 , and the nut 8 and the positioning bolt 7 have matching threads.

[0043] A positioning bushing 11 is fixedly connected to the matching block 14 , and the positioning bushing 11 is located directly below the ejector pin 9 .

[0044] A spring 10 is connected to the limit block 12 , one end of the spring 10 is fixedly connected to the base 16 , and the other end of the spring 10 is fixedly connected to the top of the ejector pin 9 .

[0045] Reference Figure 2 By means of the provided spring 10 , when the external press is not pushing down the ejector pin 9 , the ejector pin 9 is quickly reset under the elastic force of the spring 10 .

[0046] The matching block 14 is provided with an exhaust hole 1401 .

[0047] Through the exhaust hole 1401 , when air is blown into the elastic pin, the gas can be discharged from the exhaust hole 1401 to prevent the elastic pin from floating.

[0048] Reference Figure 1-Figure 3 During use, the elastic pin is sent into the material port of the slider 3 through the feed pipe 1 and the pipe joint 2 by air blowing. At this time, the opposing optical fiber body 4 on the matching block 14 senses the elastic pin, and the cylinder 5 is extended at this time. The cylinder 5 will push the slider 3 connected to its driving end to move. After moving one end distance, the slider 3 will drive the elastic pin to move to the press-fitting position. At this time, the opposing optical fiber body 4 on the matching block 14 detects the product again. At this time, the external press pushes the top pin 9 downward, and the top pin 9 will pass through the material port of the slider 3 when it is pressed downward, and then the elastic pin will be pressed into the product aperture. After the press-fitting is completed, the top pin 9 moves up and resets. At this time, the cylinder 5 drives the slider 3 to retract and return to its original position. At this time, the next elastic pin enters the slider 3 through the feed pipe 1 and the pipe joint 2 again, and the above press-fitting process is repeated.

[0049] It should be noted that during the working process, if blockage occurs, the push pin 9 can be pushed down first, and the elastic pin in the discharge port can be pressed down by the push pin 9, and then the slide block 3 can be pushed in by the cylinder 5 to send in a new elastic pin. At this time, the push pin 9 is pressed down again. If the elastic pin is pushed out, it means that the blockage problem has been solved and production can continue.

[0050] The elastic pins are conveyed and pressed by the device, which improves the stability of the elastic pins during feeding, reduces the time for troubleshooting when the material is blocked, and improves production efficiency.

[0051] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
