[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model embodiment provides a feeding device for CNC equipment, including a base 1. A transmission mechanism is installed on the base 1 to drive a conveyor belt 22 in intermittent motion, facilitating the intermittent transport of parts to the CNC machine room 4 for processing. A clamping mechanism is installed on the transmission mechanism to clamp and fix irregularly shaped parts, improving the practicality of the clamping mechanism. The CNC machine room 4 is installed on the base 1; the CNC machine room 4 is existing technology and will not be described in detail. The transmission mechanism includes a vertical plate 21, which is fixedly installed on the base 1. The vertical plate 21 is rotatably connected to the first conveyor roller 23 and the second conveyor roller 27. The first conveyor roller 23 and the second conveyor roller 27 are meshed with the conveyor belt 22. The conveyor belt 22 is meshed with the first conveyor roller 23 and the second conveyor roller 27. The conveyor belt 22 is set up in conjunction with the clamping mechanism to transport parts. The vertical plate 21 is rotatably connected to the support roller 24. The support roller 24 is set up to improve stability. The end of the second conveyor roller 27 is fixedly installed with a box body 211. The box body 211 is set up to support the sliding of the limiting block 212.

[0031] The clamping mechanism includes a mounting plate 31, which is fixedly mounted on the conveyor belt 22. The mounting plate 31 is used for mounting the support seat 32. The support seat 32 is fixedly mounted on the mounting plate 31 and is used to support the rotation of the lead screw 38. The lead screw 38 is rotatably connected to the inner wall of the support seat 32. The lead screw 38 is used to drive the slider 33 to slide linearly along the surface of the mounting plate 31. The slider 33 is threadedly connected to the lead screw 38 and slides on the surface of the mounting plate 31. The slider 33 is used to support the installation of the bracket 39.

[0032] The front of the box 211 is open. The shape of the box 211 is cylindrical. The inner wall of the box 211 has a limiting groove. The limiting groove is arc-shaped and there are four limiting grooves. They are evenly distributed in a ring along the inner wall of the box 211. The limiting groove is designed to support the sliding of the limiting block 212.

[0033] A strip plate 28 is fixedly installed at one end of the box body 211. The strip plate 28 is set to support the rotation of the circular roller 29. The circular roller 29 is rotatably connected to the strip plate 28. The circular roller 29 is cylindrical in shape. There are four circular rollers 29, which are evenly distributed in a ring around the box body 211. The circular roller 29 is set to support the drive plate 210.

[0034] A mounting base 25 is fixedly installed on the base 1. The mounting base 25 is designed to support the installation of the first motor 26. The first motor 26 is fixed to the top of the mounting base 25. The first motor 26 is designed to drive the drive plate 210 and the limit block 212 to rotate.

[0035] A drive plate 210 is fixedly installed on the shaft end of the first motor 26. The drive plate 210 is strip-shaped. The drive plate 210, together with the roller 29, is used to drive the box 211 to rotate. A limit block 212 is fixedly installed on one side of the drive plate 210. The limit block 212 is inside the box 211 and serves to limit the movement of the box 211.

[0036] The mounting plate 31 is square in shape. A second motor 37 is fixedly mounted on the mounting plate 31. The second motor 37 has forward and reverse rotation functions. The second motor 37 is set to drive the lead screw 38 to rotate. The second motor 37 is set horizontally, and the shaft end of the second motor 37 is fixedly connected to one end of the lead screw 38.

[0037] The slider 33 is a square block. A bracket 39 is fixedly installed at one end of the slider 33. The bracket 39 is used to support the installation of the mounting frame 34. The mounting frame 34 is rotatably connected to the inner wall of the bracket 39. The mounting frame 34 is used to support the rotation of the extrusion roller 310.

[0038] The inner wall of the mounting bracket 34 is rotatably connected to a compression roller 310. The compression roller 310 is cylindrical in shape and is used to compress one end of the fixing rod 36.

[0039] A receiving plate 311 is fixedly installed on the mounting plate 31. The receiving plate 311 is designed to support the sliding of the fixing rod 36. The fixing rod 36 is slidably mounted on the receiving plate 311. The fixing rod 36 is composed of a cylindrical rod and a circular plate. The fixing rod 36, together with the clamping plate 312, is used to clamp and fix the parts. A spring 35 is fixedly installed on the side of the receiving plate 311. The spring 35 is wound around the fixing rod 36. One end of the spring 35 is fixedly connected to one end of the fixing rod 36. The spring 35 ensures that one end of the fixing rod 36 is always in close contact with the extrusion roller 310.

[0040] A clamping plate 312 is fixedly installed on the mounting plate 31. The clamping plate 312 is V-shaped. The clamping plate 312, together with the fixing rod 36, serves to clamp and fix the parts.

[0041] When loading is required in CNC machine room 4, the part is placed between the fixed rod 36 and the clamping plate 312, with the part contacting the clamping plate 312. The second motor 37 is then started, driving the lead screw 38 to rotate. The lead screw 38 drives the slider 33 to slide linearly along the surface of the mounting plate 31. As the slider 33 slides linearly, it drives the fixed rod 36 to slide linearly along its through hole with the receiving plate 311 via the bracket 39, mounting frame 34, and extrusion roller 310. When one of the fixed rods 36 contacts the part, it will generate a reaction force. When one of the compression rollers 310 is compressed, the mounting frame 34 will deflect around the rotation point between itself and the bracket 39. During the deflection of the mounting frame 34, the other compression roller 310 will deflect forward. When the other compression roller 310 deflects forward, it will move the other fixing rod 36 forward until the other fixing rod 36 contacts the part, thereby achieving the purpose of fixing the part. With the above settings, it can be used to fix irregular parts, which helps to improve the practicality of the clamping mechanism.

[0042] After the parts are clamped and fixed in sequence, as shown in the attached document. Figure 3 As shown, the specific positional relationship between the first motor 26, the drive plate 210, and the limiting block 212 can be observed. The axis of rotation of the first motor 26 is eccentrically arranged with the center line of the box 211. When the shaft of the first motor 26 rotates 180 degrees clockwise, the drive plate 210 and the limiting block 212 simultaneously complete a 180-degree rotation. During this rotation, the drive plate 210 comes into contact with the roller 29 on the right side, while the limiting block 212 completely disengages from the limiting groove.

[0043] As the rotation continues, the drive plate 210, through the linkage of the roller 29 and the strip plate 28, drives the box 211 to start rotating. When the shaft of the first motor 26 completes a 270-degree clockwise rotation, the drive plate 210 disengages from the roller 29; the limiting block 212 accurately enters the limiting groove of the box 211, achieving precise positioning and fixation of the box 211.

[0044] This motion cycle will continue. When the drive plate 210 contacts the roller 29 again, a new motion cycle will begin. Through the above mechanism design, the box 211 achieves precise intermittent rotational motion. During the motion: the box 211 drives the second conveyor roller 27 to rotate synchronously and intermittently; the second conveyor roller 27 cooperates with the first conveyor roller 23 to jointly drive the conveyor belt 22 to achieve intermittent conveying; ultimately, the production requirement of intermittently conveying the parts on the clamping mechanism to the CNC machine room 4 for processing according to the set rhythm is achieved.

[0045] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
