[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-8As shown, a feeding device for machining shaft workpieces includes a frame 1. The frame 1 is equipped with a transport component 2, a unloading component 3, and a arranging component 4. The frame 1 includes a loading end and a unloading end. The unloading component 3 is located at the unloading end of the frame 1, and the arranging component 4 is located below the unloading component 3. The transport component 2 includes a first motor 21, a shaft mounting frame 22, a transmission frame 231, a first mounting base 24, and a second mounting base 25. The first motor 21, shaft mounting frame 22, first mounting base 24, and second mounting base 25 are all mounted on the frame 1. The transmission frame 231 is arranged between the shaft mounting frames 22. The transmission frame 231 has a first end and a second end. The first end of the transmission frame 231 is hinged to a first connecting rod 241, and the second end of the transmission frame 231 is hinged to a second connecting rod 251. The other end of the first connecting rod 241 is hinged to the first mounting base 251. Mounting base 24, the other end of the second connecting rod 251 is hinged to the second mounting base 25, the hinge shaft of the first connecting rod 241 and the first mounting base 24 is driven by the first motor 21. In this application, the hinge shaft of the first connecting rod 241 and the first mounting base 24 and the hinge shaft of the second connecting rod 251 and the second mounting base 25 are driven by a transmission member 26. In this application, the transmission member 26 is a chain drive. The shaft mounting frame 22 is provided with a plurality of shaft mounting slots 221. The transmission frame 231 is provided with a transmission plate. The transmission plate is provided with a plurality of grooves 230 for placing shaft parts. In this application, there are two transmission plates and they are symmetrically installed on the transmission frame 231. The transmission frame 231 moves back and forth in the height and length directions by rotating the first connecting rod 241 and the second connecting rod 251, thereby realizing the function of transporting shaft parts.

[0031] In a further optimized version of this application, there are two first mounting bases 24 and second mounting bases 25, which are symmetrically arranged on both sides of the shaft mounting frame 22 along the width direction. Each first mounting base 24 is equipped with a first connecting rod 241, and each second mounting base 25 is equipped with a second connecting rod 251. One of the first connecting rods 241 is connected to the hinge shaft of the first mounting base 24 and the first motor 21 through a chain drive. The other first connecting rod 241 is connected to the hinge shaft of the first mounting base 24, and the second connecting rod 251 on the same side is connected to the hinge shaft of the second mounting base 25 through a chain drive.

[0032] The feeding assembly 3 includes a feeding shell 32. A cylinder 31 mounted on the frame 1 is provided above the feeding shell 32. The output end of the cylinder 31 moves reciprocally in the height direction toward the feeding shell 32. A sliding block 311 is installed at the output end of the cylinder 31. The feeding shell 32 is provided with a stamping channel 320 and a feeding channel 322. A push rod is slidably disposed in the stamping channel 320 at the lower end of the sliding block 311. The push rod can move reciprocally in the first and second positions of the stamping channel 320 along the axial direction. A limiting port 323 is formed at the bottom end of the stamping channel 320. The limiting port 323 is linked with the push rod so that when the push rod moves along the axial direction, it can push the shaft to drive the width of the limiting port 323 to change accordingly. The limiting port 323 is connected to the discharge end of the feeding channel 322.

[0033] When the push rod is in the first position of the stamping channel 320, the limiting port 323 is used to stop the shaft-like parts that enter the stamping channel 320 from the feeding channel 322.

[0034] When the push rod moves from the first position to the second position of the stamping channel 320, the limiting port 323 expands in the width direction under the action of the push rod, causing the shaft-like part stopped by the limiting port 323 to fall vertically from the limiting port 323 under its own gravity.

[0035] The feed shell 32 is also equipped with an elastic element 324 for ensuring that the limiting port 323 always has a tendency to contract in the width direction. The elastic element 324 described in this application is a spring. When the push rod moves from the second position to the first position of the stamping channel 320, the limiting port 323 contracts and resets in the width direction under the action of the elastic element 324.

[0036] When the cylinder 31 drives the slider and push rod to move downwards, the limiting port 323 also expands synchronously along the width direction. While the limiting port 323 expands, the shaft is initially located above the limiting port 323. As the limiting port 323 continues to expand, its width increases to the point where the shaft can fall in. At this time, the shaft enters the limiting port 323 and falls vertically under its own gravity. After the pressing is completed, the limiting port 323 shrinks to a width smaller than the diameter of the shaft, and the next shaft to be installed will fall above the limiting port 323 to wait for pressing.

[0037] The unloading shell 32 is fixedly connected to a storage compartment 34 for placing shaft parts. The upper end of the storage compartment 34 is provided with a guide channel 341. The guide channel 341 is located below the unloading end of the frame 1, so that the processed shaft can roll into the guide channel 341 and fall into the storage compartment 34 through the guide channel 341. A distribution plate 33 is movably arranged in the storage compartment 34. The distribution plate 33 is provided with an inlet hole 331 that cooperates with the inlet channel 322. The upper end of the distribution plate 33 is movably connected to the sliding block 311.

[0038] When the push rod reciprocates between the first and second positions: the material distribution plate 33 moves synchronously with the push rod in the axial direction along the stamping channel 320; and the material distribution plate 33 moves synchronously with the sliding block 311 in the radial direction along the stamping channel 320.

[0039] Furthermore, when the push rod is in the first position, the feed hole 331 is connected to the feed end of the feed channel 322; when the push rod is in the second position, the shaft parts in the storage compartment 34 enter the feed hole 331 one by one.

[0040] The storage compartment 34 has a connecting hole 342 that is always connected to the inlet end of the inlet channel 322. The distribution plate 33 is slidably engaged with the compartment wall. When the top rod is in the first position, the inlet hole 331 is connected to the inlet end of the inlet channel 322 through the connecting hole 342.

[0041] The material distribution plate 33 also has a mounting hole located above the inlet hole 331. A connecting shaft 332 is provided in the mounting hole. One end of the connecting shaft 332 is fixedly installed on the sliding block 311. The material distribution plate 33 always maintains contact with the inner wall of the storage compartment 34. The material discharge shell 32 is provided with a sliding hole 321 for the connecting shaft 332 to slide.

[0042] Furthermore, in this application, the connecting shaft 332 is a bolt, and a nut that is threadedly engaged with the connecting shaft 332 is provided in the mounting hole. The nut is used to fix the connecting shaft 332 and prevent the connecting shaft 332 from moving along its axial direction.

[0043] When the stamping unit is in the first position, the feed hole 331 is connected to the connecting hole 342.

[0044] More preferably, the storage compartment 34 has a storage cavity 343, and the bottom surface of the storage cavity 343 is arranged as an upward-opening slope.

[0045] The bottom of the storage compartment 34 is provided with a clearance groove 344 for the material distribution plate 33 to pass through.

[0046] The arrangement assembly 4 includes a second motor 41, a third mounting base 44, and a movable plate 42. The lower end of the movable plate 42 is provided with a movable block 421, and a storage basket 43 is placed on the movable plate 42. The output end of the second motor 41 is provided with a lead screw 411. One end of the lead screw 411 is rotatably engaged with the third mounting base 44. The movable block 421 is threadedly engaged with the outer circumference of the lead screw 411. The movable block 421 moves back and forth along the axial direction of the lead screw 411 through the rotation of the lead screw 411, thereby realizing the back and forth movement of the storage basket 43 along the axial direction of the lead screw 411, thus realizing the automatic arrangement of fallen shaft parts.

[0047] The frame 1 is equipped with a counter 46 located below the limiting port 323. The counter 46 is used to detect falling shaft parts. The counter 46 is electrically connected to the first motor 21 and the second motor 41. When the number of shaft parts in the storage basket 43 reaches a preset value, the first motor 21 is turned off, and the second motor 41 drives the lead screw 411 to rotate, thereby driving the storage basket 43 to move away from the motor.

[0048] The arrangement assembly 4 also includes two fourth mounting seats 47 symmetrically arranged on both sides of the lead screw 411. A guide shaft 45 is provided between the fourth mounting seat 47 and the third mounting seat 44. The two guide shafts 45 guide the movement of the movable block 421 and support the movable block 421.
