Description

Technical Field

[0001] This utility model relates to the field of elastic cylindrical pin processing technology, and more specifically, it relates to a feeding device for processing elastic cylindrical pins. Background Technology

[0002] Elastic cylindrical pins, also known as spring pins, are headless, hollow cylindrical bodies with axial slots and chamfered ends. They are used for positioning, connecting, and fixing parts. They need to have good elasticity and shear resistance. The outer diameter of these pins is slightly larger than the assembly hole diameter. During processing, elastic cylindrical pins need to be fed by a feeding device.

[0003] Chinese utility model application CN202420606916.0 discloses an elastic cylindrical pin feeding device, which describes that "the cylindrical pin rolls onto the feeding plate 10, and then rolls into the cylindrical groove of the feeding disc 7, pressing against the ejector plate 26. Through the rotation of the feeding disc 7, the cylindrical pin is limited by the limiting plate 8. When the feeding disc 7 rotates, the spring 25 pushes the ejector plate 26, conveying the cylindrical pin to the surface of the conveyor belt 12, where it is stopped by two adjacent limiting rods 1." 3. Limiting the position facilitates transmission and prevents the cylindrical pins from shifting or jamming. It also helps to limit the position of the cylindrical pins, reducing the possibility of them falling off due to rolling and causing damage. It is also beneficial for the neatness of the feeding process, making it more convenient and reducing the workload of the staff, thereby improving the feeding efficiency of the cylindrical pins. The cylindrical pins are fed through a rotatable feeding disc, which has several slots arranged in a circumferentially equidistant array on the feeding disc to achieve one-to-one feeding of the cylindrical pins.

[0004] Although the elastic cylindrical pin feeding device disclosed in the above patent can feed the cylindrical pins one by one, which is beneficial to the neatness of the feeding, the groove on the feeding plate can only match one size and specification of elastic cylindrical pins. It is more convenient when feeding elastic cylindrical pins of one specification, but it cannot match when it is necessary to feed elastic cylindrical pins of different specifications. Therefore, in order to solve the above technical problems, this application proposes a feeding device for processing elastic cylindrical pins. Utility Model Content

Material box 2, installed on the inner side wall of frame 1, includes a box body 201. A discharge nozzle 202 is installed at the bottom outlet of the box body 201. First sliding grooves 203 are provided on both sides of the discharge nozzle 202. A baffle plate 7 is slidably connected in the first sliding grooves 203. Conveyor belt 6 is located below the feeding assembly 3. This utility model discloses... The feeding device for processing elastic cylindrical pins has a first bottom bar 803 and a second bottom bar 804 forming a "V" shape in the V-groove 802 of the feeding disc 8, which are "V" shaped support members. By adjusting the component 9, the abutment bar 904 can be driven to move synchronously along the path from the center of the disc 801 to the bottom hinge of the first bottom bar 803 and the second bottom bar 804, and the opening and closing angle of the "V" shaped support members can be adjusted to adapt to the feeding of different types of elastic cylindrical pins.

[0030] Furthermore, the feeding assembly 3 is disposed on the inner side wall of the frame 1. The feeding assembly 3 includes a feeding disc 8 and an adjusting component 9. The feeding disc 8 includes a disc shell 801. The outer side wall of the disc shell 801 is provided with a plurality of V-shaped grooves 802 arranged in a circumferentially equidistant array. The top two ends of the inner side wall of the V-shaped grooves 802 are respectively slidably hinged to a first bottom strip 803 and a second bottom strip 804. The bottoms of the first bottom strip 803 and the second bottom strip 804 are hinged together and form a "V" shape with each other. The adjusting component 9 includes abutment bars 904 disposed at the bottom hinge of the first bottom strip 803 and the second bottom strip 804. There are a plurality of abutment bars 904, which can move synchronously along the axis of the disc shell 801. The path at the bottom hinge of the first bottom strip 803 and the second bottom strip 804 is translated. The top of the first bottom strip 803 and the second bottom strip 804 are both hinged with slide strips 806. The disc shell 801 is provided with a second slide groove 805 corresponding to the slide strip 806. The slide strip 806 is slidably connected to the inner side wall of the second slide groove 805. The power input end of the disc shell 801 is connected to the first motor 10. The first bottom strip 803 and the second bottom strip 804, which form a "V" shape, are provided in the V-shaped groove 802 of the feeding disc 8. That is, the "V" shaped support is formed by the mutual "V" shape. The opening and closing angle of the "V" shaped support can be adjusted to adapt to the feeding work of different types of elastic cylindrical pins.

[0031] Furthermore, the drive assembly 5, mounted on the frame 1, can drive the baffle plates 7 to move synchronously relative to each other. The drive assembly 5 includes a bidirectional threaded screw 502 rotatably connected to the frame 1. The power input end of the bidirectional threaded screw 502 is connected to a second motor 501. Both ends of the bidirectional threaded screw 502 are threadedly connected to screw sleeves 503. The screw sleeves 503 are connected to the baffle plates 7 through the rod body. The baffle plates 7 can be controlled to move synchronously closer or further away from each other. The distance between the two baffle plates 7 can be adjusted so that only one elastic cylindrical pin can pass through, which is convenient for feeding one by one.

[0032] Furthermore, the adjustment component 9 includes a spiral scroll 902 rotatably connected within the housing 801.

A mounting plate 905 is provided outside the rack 903 and limits its movement. The power input end of the spiral scroll 902 is connected to a third electric motor 906.

[0033] Working principle: The feeding device for processing elastic cylindrical pins disclosed in this utility model has a first bottom strip 803 and a second bottom strip 804 forming a "V" shape in the V-groove 802 of the feeding disc 8, which are "V" shaped support members. By adjusting the component 99, the support strip 904 can be driven to move synchronously along the path from the axis of the disc 801 to the bottom hinge of the first bottom strip 803 and the second bottom strip 804, and the opening and closing angle of the "V" shaped support member can be adjusted to adapt to the feeding of different types of elastic cylindrical pins. The process involves filling the material bin 2 with elastic cylindrical pins to be fed, aligning the pins parallel to the discharge nozzle 202 so they can leak out. An external power supply activates the second motor 501 via an external switch. This motor, driven by the double-threaded screw 502 and screw sleeve 503, adjusts the distance between the two baffle plates 7 to allow the current type of elastic cylindrical pin to be discharged one by one. An external power supply then activates the third motor 906 via an external switch. The machine 906 drives the spiral scroll 902 to rotate. Several racks 903 are circumferentially and equidistantly connected on the outer wall of the spiral scroll 902. Each rack 903 has a stop bar 904 fixed to its outer end. A mounting plate 905 is provided around each rack 903, and the racks 903 are limited by the mounting plate 905. The racks 903 and the stop bars 904 slide outwards or inwards along the grooves on the mounting plate 905, adjusting the tension between the first bottom bar 803 and the second bottom bar 804, which form a "V" shape. The slide bar 806... The second slide rail 805 slides inward, allowing the "V"-shaped support to open and close smoothly to fit the elastic cylindrical pin of the current diameter. The elastic cylindrical pin of the current diameter can be supported by the "V"-shaped support at two points and accommodated in the V-shaped groove 802. Then, the first motor 10 is turned on, causing the first motor 10 to drive the feeding assembly 3 to rotate clockwise and feed the materials one by one (the first motor 10, the second motor 501 and the third motor 906 are all existing products on the market and are all connected to external switches and external power sources).
