[0038] In order to improve the working efficiency of old lathes with a long history, some technologies use vibration plate loading instead of manual loading. During the loading process, the workpiece extends out from the discharge port of the vibration plate, and then is grasped by the clamp and moved to the lathe for processing. However, due to the uncertainty of the displacement of the workpiece caused by the vibration of the vibration plate during the loading process, the length of the workpiece when it extends out of the discharge port is inconsistent. As a result, during the processing, the workpiece may fall from the discharge port of the vibration plate, or fall due to insufficient clamping position of the clamp, thereby affecting the processing efficiency.

[0039] Based on the above problems, the first embodiment of the utility model proposes a loading device, which can be used for loading on a lathe to prevent the workpiece 1000 from falling, thereby ensuring work efficiency. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a feeding device according to the first embodiment of the utility model. Figure 2 for Figure 1 The structural schematic diagram of the positioning mechanism in the figure shows that the feeding device of this embodiment includes: a vibration plate 100, a positioning mechanism 200 and a clamping mechanism 300.

[0040] The vibration disk 100 includes a first vibrator 110 and a silo 120. The silo 120 is connected to the first vibrator 110. The silo 120 has a receiving chamber 121 and a first discharge port 122 connected to the receiving chamber 121. The receiving chamber 121 is used to store the workpiece 1000. The vibration of the first vibrator 110 can drive the silo 120 to vibrate so that the workpiece 1000 is discharged from the first discharge port 122 (the working principle of the vibration disk 100 is a well-known technology and will not be described in detail here). The positioning mechanism 200 includes a positioning member 210, a first top block 220, a first power member 230, a second top block 240 and a second power member 250 (such as Figure 2As shown in the figure, the positioning member 210 has a positioning groove 211, and a first feed port 212 and a second discharge port 213 connected to the positioning groove 211, the first feed port 212 is connected to the first discharge port 122, the first power member 230 can be, for example, a motor, a cylinder or a hydraulic cylinder, the first power member 230 is connected to the first top block 220, and is used to drive the first top block 220 to move between the first feed port 212 and the second discharge port 213, so as to drive the workpiece 1000 from the first feed port 212 to the second discharge port 213. The second power member 250 can be, for example, a motor, a cylinder or a hydraulic cylinder, the second power member 250 is connected to the second top block 240, and is used to drive the second top block 240 to move, so that the workpiece 1000 partially extends from the second discharge port 213. The clamping mechanism 300 includes a clamping member 310, which is used to clamp the workpiece 1000 extending from the second discharge port.

[0041] Specifically, when the loading device of this embodiment is used for loading on a lathe, the vibration plate 100, the positioning mechanism 200 and the clamping mechanism 300 are connected to the lathe body, and the workpiece 1000 is accommodated in the accommodating cavity 121. The workpiece 1000 is discharged from the first discharge port 122 by the vibration of the first vibrator 110, and enters the positioning groove 211 through the first feed port 212. Then, the first top block 220 moves the workpiece 1000 to the second discharge port 213, and drives the workpiece 1000 through the second top block 240 so that the workpiece 1000 partially extends out of the second discharge port 213. The clamping mechanism 300 is used to transfer the workpiece 1000 extending through the second discharge port 213 to the clamping jaw 700 of the lathe for fixation. It can be understood that during the transfer of the workpiece 1000, the length of the workpiece 1000 extending from the second outlet 213 can be accurately controlled by the moving distance of the second top block 240, thereby reducing the risk of the workpiece 1000 falling from the first outlet 122, and at the same time ensuring that the clamping member 310 can clamp a sufficient length, thereby reducing the risk of the workpiece 1000 falling from the clamping mechanism 300. Therefore, when the loading device of this embodiment is used for a lathe, the processing efficiency of the lathe can be ensured. Therefore, when the loading device of this embodiment is used for a lathe, the processing efficiency of the lathe can be ensured.

[0042] It should be noted that the attached Figure 1 The fact that the middle clamping member 310 has three clamping parts 311 cannot be interpreted as the only limitation of this embodiment. According to requirements, the clamping parts 311 can be provided in any number such as two, three or four, as long as the workpiece 1000 can be stably clamped.

[0043] Reference Figure 2In some embodiments, the positioning member 210 also has a penetration opening 214, the penetration opening 214 is connected to the positioning groove 211, the second top block 240 is penetrated by the penetration opening 214, the second power member 250 is a cylinder, and the positioning mechanism 200 also includes a first limiting member 260, which is connected to the second top block 240 and is located outside the positioning groove 211. The first limiting member 260 can be supported on the positioning member 210 to limit the moving distance of the second top block 240, thereby improving the positioning accuracy of the workpiece 1000 and further reducing the risk of the workpiece 1000 falling.

[0044] Reference Figure 2 On the basis of the above embodiment, the positioning mechanism 200 also includes a connecting member 270, the cylinder includes a piston rod 251, the connecting member 270 connects the piston rod 251 and the second top block 240, and the connecting member 270 includes a first limiting member 260. Therefore, there is no need to additionally set up an independent structure as the first limiting member 260, thereby making the structure of the positioning mechanism 200 simpler and reducing the cost of the positioning mechanism 200 itself.

[0045] Reference Figure 2 In some embodiments, the first limit member 260 can move relative to the second top block 240 along the moving direction of the second top block 240, and can be fixed to the second top block 240 to adjust the moving distance of the second top block 240. For example, the second top block 240 has a thread on the outside, and the first limit member 260 has a threaded hole. The first limit member 260 is sleeved on the second top block 240 and connected by threads. Therefore, the position of the first limit member 260 on the second top block 240 can be adjusted by rotating the first limit member 260, thereby adjusting the distance between the first limit member 260 and the positioning member 210 to control the moving distance of the second top block 240, thereby controlling the length of the workpiece 1000 extending from the second discharge port 213, thereby improving the practicality of the loading device of this embodiment. Specifically, in order to prevent the workpiece 1000 from falling from the second discharge port 213, it is necessary to ensure that the center of the workpiece 1000 is located inside the second discharge port 213, and for workpieces 1000 of different lengths, the distance between the center of gravity and the end is also different. Based on this, in order to enable the feeding device of this embodiment to adapt to more workpieces 1000 of different lengths, the first limiter 260 of this embodiment can move relative to the second top block 240 to adjust the distance between the limiter and the positioning member 210, so that the position of the first limiter 260 can be adjusted according to the workpieces 1000 of different lengths to ensure that the center of gravity of the workpiece 1000 is located inside the second discharge port 213, thereby improving the feeding device of the utility model.

[0046] Reference Figure 1On the basis of the above embodiment, the clamping mechanism 300 further includes a fourth power member 340 and a support member 330, the third power member 320 is connected to the support member 330, the fourth power member 340 is mounted on the support member 330 and connected to the clamping member 310, and the fourth power member 340 is used to drive the clamping member 310 to reciprocate along the direction in which the workpiece 1000 extends out of the second discharge port 213. Thus, during the working process, the clamping member 310 can be driven to move by the fourth power member 340 to adjust the contact length between the clamping member 310 and the workpiece 1000, thereby improving the stability of the workpiece 1000 when being clamped. In addition, when the workpiece 1000 is transferred to the clamping jaw 700, the claw of the clamping jaw 700 can be avoided by moving the workpiece 1000, thereby preventing the claw of the clamping jaw 700 from interfering with the movement of the workpiece 1000, thereby improving the practicality of the feeding device of this embodiment.

[0047] Reference Figure 2 In some embodiments, the positioning mechanism 200 also includes a second limit member 280, which is connected to the positioning member 210 and is arranged opposite to the first top block 220. The second limit member 280 can support the workpiece 1000 to limit the workpiece 1000 at the second discharge port 213, thereby improving the position accuracy of the workpiece 1000 and ensuring that the workpiece 1000 is aligned with the second discharge port 213, so that the workpiece 1000 can be smoothly extended through the second discharge port 213, thereby preventing blockage and improving work efficiency.

[0048] Reference Figure 2 and Figure 3 , Figure 3 for Figure 1 Schematic diagram of the structure of another working state of the positioning mechanism in the figure. In some embodiments, the second limiting member 280 is connected to the first top block 220 as an integral structure, and is defined to form a limiting groove 290 that passes through along a first direction. The first direction is the moving direction of the second top block 240. The positioning mechanism 200 has a first state (such as the limiting groove 290 is aligned with the first feed port 212) Figure 2 ), and the second state where the limiting groove 290 is aligned with the second discharge port 213 (as shown Figure 3As shown), the workpiece 1000 can be accommodated in the limiting groove 290. Specifically, when the limiting groove 290 is in the first state, the workpiece 1000 discharged through the first discharge port 122 can enter the limiting groove 290, and then driven by the first power member 230, the limiting groove 290 is switched to the second state and aligned with the second discharge port 213. It can be known that during the movement and positioning of the workpiece 1000, the workpiece 1000 does not need to be squeezed between the first top block 220 and the second limiting member 280, thereby avoiding the workpiece 1000 from being damaged by pressure, thereby improving the quality of the workpiece 1000, and making it easier for the workpiece 1000 to be ejected by the second top block 240. In addition, for some parts that do not require turning on the entire side, friction between the radial side of the workpiece 1000 and the workpiece 1000 can also be prevented, thereby reducing the wear on the surface of the workpiece 1000, thereby improving the quality of the workpiece 1000.

[0049] Reference Figure 3 In some embodiments, the first feed port 212 also has two guide surfaces 215 arranged opposite to each other. As the workpiece 1000 enters the first feed port 212, the distance between the two guide surfaces 215 gradually decreases, so that the workpiece 1000 can enter the positioning groove 211 through the first feed port 212 more smoothly, thereby reducing the risk of blockage and improving work efficiency.

[0050] Reference Figure 1 In some embodiments, the feeding device further includes a vibrating feeding mechanism 400, which includes a second vibrator 410 and a conveying member 420, wherein the conveying member 420 is connected to the second vibrator 410, and the conveying member 420 has a conveying groove 421, one end of which is connected to the first discharge port 122, and the other end of which is connected to the second discharge port 213. Therefore, during the feeding process, the workpiece 1000 can enter the conveying groove 421 after being discharged through the first discharge port 122, and the moving speed can be accelerated by the vibration of the second vibrator 410, thereby improving the working efficiency of the feeding device of this embodiment.

[0051] Reference Figure 1 and Figure 4 , Figure 4This is a schematic diagram of the structure of another feeding device according to the first embodiment of the utility model. On the basis of the above embodiment, the vibrating feeding mechanism 400 further includes a shielding member 430, which covers the upward notch of the conveying trough 421. The shielding member 430 also has a guide hole 431, which passes through the shielding member 430 and is arranged obliquely along the conveying direction of the workpiece 1000. Specifically, it can be known that during the operation of the second vibrator 410, the workpiece 1000 will be driven to move and vibrate, thereby there may be a risk of the workpiece 1000 falling from the conveying trough 421. Based on this, the shielding member 430 is arranged at the upward notch of the conveying trough 421 in this embodiment to prevent the workpiece 1000 from falling. Furthermore, the shielding member 430 also has a guide hole 431, which is arranged obliquely along the conveying direction of the workpiece 1000, so that it can be observed through the guide hole 431 whether there is material blockage in the lower conveying groove 421. At the same time, when there is material blockage in the limiting groove 290, a tool can be extended into the conveying groove 421 to apply a thrust to the workpiece 1000 in the conveying groove 421 to clear the conveying groove 421. Therefore, the conveying groove 421 can be cleared without removing the shielding member 430, so that the loading device of this embodiment is easier to maintain.

[0052] Reference Figure 5 , Figure 5 The lathe of the second embodiment of the utility model comprises: a lathe body and a loading device of the first embodiment. The lathe body comprises a bracket 500, a rotating shaft 600 and a clamp 700, the rotating shaft 600 is rotatably connected to the bracket 500, the clamp 700 is connected to the rotating shaft 600, and the vibration plate 100, the positioning mechanism 200 and the clamping mechanism 300 are all connected to the bracket 500. For example, the third power member 320 is a cylinder, and the cylinder is vertically arranged so that the clamp 310 can move up and down, and the second discharge port 213 is located above the clamp 700, that is, the opening direction of the second discharge port 213 and the axial direction of the rotating shaft 600 are located in the same vertical plane, so that the clamp 310 can move between the second discharge port 213 and the clamp 700 by moving up and down, thereby moving the workpiece 1000 from the second discharge port 213 to the clamp 700.

[0053] Specifically, the positioning mechanism 200 of the loading device includes a positioning member 210, a first top block 220 and a second top block 240, wherein the positioning member 210 has a positioning groove 211, a first feed port 212 and a second discharge port 213. When the workpiece 1000 enters the positioning groove 211 through the first feed port 212, the first top block 220 moves the workpiece 1000 to the second discharge port 213, and drives the workpiece 1000 through the second top block 240, so that the workpiece 1000 partially extends out of the second discharge port 213. Therefore, the length of the workpiece 1000 extending from the second discharge port 213 can be accurately controlled by the moving distance of the second top block 240, so that the workpiece 1000 falls from the first discharge port 122, and can ensure that the clamping member 310 can clamp a sufficient length to prevent the workpiece 1000 from falling from the clamping mechanism 300, thereby ensuring the processing efficiency of the lathe.
