Description

Technical Field

[0001] The present application relates to the technical field of electronic pin processing equipment, and in particular to a feeding device for processing pinhole parts of an electrical connector. Background Art

[0002] Pin electrical connector is a component used to connect circuits, usually consisting of two parts: a pin and a socket. The pin is a slender part made of metal, while the socket is a part used to accommodate the pin. Inserting the pin into the socket can establish an electrical connection for transmitting current and signals. Pin electrical connectors are widely used in electronic equipment, communication equipment, automotive electronics, aerospace and other fields.

[0003] The raw materials for processing pins are mostly copper wire coils. During the specific processing, the copper wire coils are unwound and cut into sections of copper bars, and then the copper bars are straightened. The straightened copper bars are sent to the cutting equipment to be cut into small sections of copper rods, and finally the small sections of copper rods are punched and chamfered to obtain pin components.

[0004] During the actual construction, the raw materials need to be transferred back and forth between the cutting machine, the chamfering machine and the punching machine, resulting in a cumbersome and inefficient processing of the pins. At the same time, when the existing punching machine is punching holes in the pins, the ends of the pins are exposed to the outside and lack certain protection, which is prone to deformation and affects the processing quality of the pins. Summary of the invention

[0005] The present application provides a feeding device for processing pinhole parts of an electrical connector, which can facilitate chamfering and hole processing of the pin through one-time feeding. At the same time, during the hole processing process of the pin, the clamp can protect the pin to prevent it from bending and deformation, effectively improving the processing quality of the pin, and can effectively solve the problems in the background technology.

[0008] The clamping part is provided with a through hole for the copper wire to pass through.

[0009] Specifically, the number of the slide rails is no less than two.

[0010] Specifically, the central axes of the circular outer cover 1 and the circular outer cover 2 coincide with each other.

[0011] Specifically, the cylindrical slider is coaxial with the transmission shaft.

[0012] Specifically, a second gear is installed on the outer side surface of the cylindrical slider, a third gear meshing with the second gear is installed inside the first middle frame bracket, and a first gear meshing with the third gear is installed on the outer side surface of the clamping portion.

[0013] Specifically, the clamping part includes a hollow cylindrical frame, the end of the hollow cylindrical frame is provided with a slide groove, the number of the slide grooves is not less than two, and the not less than two slide grooves are evenly distributed in an annular manner on the end of the hollow cylindrical frame, the slide groove is slidably connected with a step-type clamping plate, the step-type clamping plate is connected with a positioning plate, the positioning plate is arranged close to the inner side surface of the hollow cylindrical frame, the outer side end of the positioning plate is provided with a slope one, the hollow cylindrical frame is slidably connected with an annular positioning platform through a positioning slide rail arranged on its inner side surface, the annular positioning platform is connected to the inner side surface of the hollow cylindrical frame through an electrically controlled telescopic rod, the outer side surface of the annular positioning platform is provided with an annular slope one, and the slope surface of slope one is slidably connected with the slope surface of slope two.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] 1. The feeding device for processing the pinhole parts of the electrical connector can facilitate the chamfering and hole processing of the pin by feeding the material once. At the same time, during the hole processing of the pin, the fixture can protect the pin to avoid bending and deformation, thereby effectively improving the processing quality of the pin;

[0017] 2. The copper wire can be clamped and fixed by the clamping part, and then the pneumatic telescopic rod pushes the hollow slider to move along the slide rail to pull out the copper wire. The motor drives the two clamping parts to rotate synchronously through the transmission shaft and gear transmission system, and the clamping part drives the copper bar to rotate at high speed, so that the tool and hole processing of the copper bar can be realized;

[0018] 3. When the copper bar needs to be clamped, the electric telescopic rod extends and presses down the annular positioning platform. The annular positioning platform pushes the three stepped clamping plates to move synchronously toward the center through the positioning plate. The copper bar is clamped by the three stepped clamping plates. When the copper bar needs to be loosened, the electric telescopic rod contracts and the force acting on the positioning plate is removed. At this time, the copper bar can be easily pulled out.

[0028] Specifically, the copper wire can be clamped and fixed by the clamping portion 11, and then the pneumatic telescopic rod 4 pushes the hollow slide block 8 to move along the slide rail 7, so as to pull out the copper wire.

[0032] Specifically, the through hole is used for positioning the copper wire.

[0033] Furthermore, the number of the slide rails 7 is not less than two.

The number of the slide grooves 112 is not less than two, and not less than two slide grooves 112 are evenly distributed in an annular manner at the end of the hollow cylindrical frame 111. A stepped clamp 113 is slidably connected to the slide groove 112, and a positioning plate 114 is connected to the stepped clamp 113.
