[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0040] It should also be noted that in the embodiments of this application, the same reference numerals are used to denote the same components or the same parts. For the same parts in the embodiments of this application, only one of the parts or components may be marked with a reference numeral in the figure. It should be understood that the reference numerals are equally applicable to other identical parts or components.

[0041] As described in the background art, since there is no suitable feeding device on the market, currently, when machining the flattened part of the mandrel, it is necessary to manually place the mandrels one by one into the clamping station of the flattening machine. This not only has low production efficiency but also poses a great safety hazard during manual placement.

[0042] To solve the above problems, an embodiment of this application provides a feeding device for machining the flattened part of a motor mandrel. As Figures 1-4 shown, the feeding device includes a base 10, a vertical plate 20, a magazine 30, and a pushing mechanism. The lower end of the vertical plate 20 is fixed to the base 10. The magazine 30 is arranged on one side of the vertical plate 20. The upper end of the magazine 30 is provided with a feeding port 3011, and the lower end of the magazine 30 is provided with a discharging port 3012. The magazine 30 is used to store the mandrels 1, and only a single mandrel 1 can pass through the discharging port 3012. On the base 10 directly below the discharging port 3012, a guiding groove 101 is provided. The width L of the guiding groove 101 satisfies R < L ≤ 1.1R, and the height H from the bottom of the guiding groove 101 to the discharging port 3012 satisfies R ≤ H ≤ 1.4R, where R is the diameter of the mandrel 1. The pushing mechanism includes a pushing member 60 arranged at one end of the guiding groove 101 and a push rod 50 located in the guiding groove 101 and connected to the pushing member 60. The push rod 50 can reciprocate in the guiding groove 101 under the drive of the pushing member 60 to push out the mandrels 1 from the guiding groove 101 one by one.

[0043] It can be understood that, as Figure 4 shown, the width L of the guiding groove 101 is designed to satisfy R < L ≤ 1.1R, and the height H from the bottom of the guiding groove 101 to the discharging port 3012 is designed to satisfy R ≤ H ≤ 1.4R, where R is the diameter of the mandrel 1. Thus, only one mandrel 1 falls into the guiding groove 101 each time. When the mandrel 1 in the guiding groove 101 is pushed out by the push rod 50, since the mandrel 1 at the discharging port 3012 of the magazine 30 is blocked by the push rod 50 below, it cannot fall. When the push rod 50 retracts and returns to its original position, the mandrel 1 at the discharging port 3012 falls into the guiding groove 101.

[0044] In this embodiment, a guide groove 101 is provided on the base 10 directly below the discharge port 3012 of the hopper 30. Only one mandrel 1 falls into the guide groove 101 at a time from the discharge port 3012 of the hopper 30. The push rod 50 of the pushing mechanism can move within the guide groove 101 under the drive of the pusher 60. After the push rod 50 pushes out the mandrel 1 in the guide groove 101 and resets it, another mandrel 1 falls into the guide groove 101. Through the reciprocating motion of the push rod 50, the mandrels 1 fall into the guide groove 101 one by one and are pushed out one by one by the push rod 50. In specific use, the end of the guide groove 101 away from the pusher 60 is connected to the clamping station of the milling machine. A large number of mandrels 1 are placed in the hopper 30 at one time, and the feeding is achieved by the pushing mechanism, which improves production efficiency and avoids the safety hazards of manual feeding.

[0045] In one embodiment, such as Figures 1-2 As shown, the pusher 60 includes a cylinder. The cylinder body is located at one end of the base 10 in the guide groove 101. The piston rod of the cylinder is parallel to the length direction of the guide groove 101. The push rod 50 is connected to the piston rod of the cylinder. Each extension and retraction of the cylinder drives the push rod 50 to reciprocate once, thereby feeding a mandrel 1.

[0046] It is conceivable that the pusher 60 could also be a linear drive component such as an electric cylinder.

[0047] In one embodiment, such as Figures 1-2 and Figure 4 As shown, the hopper 30 has a length direction and a width direction. For ease of understanding and explanation, an XY rectangular coordinate system is established in the figure, where the length direction of the hopper 30 is the X-axis direction, and the width direction of the hopper 30 is the Y-axis direction. The axial direction of the mandrel 1 located inside the hopper 30 is parallel to the length direction of the hopper 30. The interior of the hopper 30 is provided with a storage section 301, a transition section 302, and a discharge section 303, sequentially from the feeding port 3011 to the discharge port 3012. The width of the storage section 301 is greater than the width of the discharge section 303, and the width of the transition section 302 decreases from top to bottom. The storage section 301 is wider to store a larger number of mandrels 1, while the width of the discharge section 303 is slightly larger than the diameter of the mandrel 1 to allow a single mandrel 1 to pass through.

[0048] In one specific embodiment, such as Figures 1-3 As shown, the hopper 30 includes a left hopper body 31 and a right hopper body 32 that is structurally symmetrical to the left hopper body 31. The left hopper body 31, the right hopper body 32 and the vertical plate 20 together form a space for storing mandrels. The distance between the left hopper body 31 and the right hopper body 32 in the length direction of the hopper 30 is adjustable to accommodate mandrels of different lengths.

[0049] By designing the hopper 30 as a combination of left hopper body 31 and right hopper body 32, and the adjustable distance between the left hopper body 31 and right hopper body 32 in the length direction of the hopper 30, the range of spindle lengths applicable to the feeding device is expanded.

[0050] Specifically, the left compartment 31 includes a first connecting plate 311, a first end plate 312 with one end perpendicularly connected to the first connecting plate 311, and a first side plate 313 with one end perpendicularly connected to the first end plate 312 away from the first connecting plate 311; the right compartment 32 includes a second connecting plate 321, a second end plate 322 with one end perpendicularly connected to the second connecting plate 321, and a second side plate 323 with one end perpendicularly connected to the second end plate 322 away from the second connecting plate 321. The upright plate 20 is provided with a strip hole 201 extending along the length direction of the hopper 30. The first connecting plate 311 is fixed on the upright plate 20, and the second connecting plate 321 is installed on the upright plate 20 by connecting bolts 40 passing through the strip hole 201. The first end plate 312 and the second end plate 322 are arranged opposite to each other in the length direction of the hopper 30. The first end plate 312, the second end plate 322, the first side plate 313, the second side plate 323 and the upright plate 20 together form a space for storing the mandrel.

[0051] By connecting the bolt 40 and the slot 201, the right compartment 32 can be adjusted left and right according to the size and length of the shaft core.

[0052] Furthermore, to accommodate the length adjustment of the hopper 30, the position of the pusher 60 also needs to be adjusted accordingly. Specifically, the pusher 60 is mounted on the base 10 via a mounting bracket 70, the position of which is adjustable along the length of the guide groove 101.

[0053] The mounting bracket 70 includes a connecting bracket 72 and a mounting bracket 71 that is perpendicularly connected to one end of the connecting bracket 72. The connecting bracket 72 has a waist-shaped hole, and the base 10 has a mounting hole. The connecting bracket 72 is fixed to the base 10 by screws passing through the waist-shaped hole. The mounting bracket 71 is opposite to one end of the guide groove 101, and the pusher 60 is mounted on the mounting bracket 71.

[0054] The left and right positions of the mounting bracket 70 can be adjusted by using screws and slotted holes.

[0055] In some embodiments, such as Figure 2 and Figure 4 As shown, a mounting plate 80 is connected to the side of the upright plate 20 away from the hopper 30. The mounting plate 80 has connection holes for external connections. The entire feeding device can be installed at the corresponding position on the milling machine through the connection holes on the mounting plate 80, thereby fixing the feeding device.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
