Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] This utility model relates to a feeding device for ball screw processing, which is used to transport the raw material bar (the bar is cylindrical) for ball screw processing. It includes a feeding structure and a picking structure. The feeding structure is used to transport the bar, and the picking structure is used to clamp a single bar and transfer it to the subsequent processing station for processing (such as grinding, polishing, cutting, thread rolling, etc.).

[0019] like Figure 1-3As shown, the feeding structure includes a second vertical plate 31, a fixed plate 32, a folding plate 33, a bottom baffle 34, a side baffle 35, a top baffle 36, a material trough 37, an adjusting groove 38, a fixing hole 39, a first extension plate 40, a second extension plate 41, an infeed plate 42, a third extension plate 43, and a fourth extension plate 44. The second vertical plate 31 is a metal plate and there are at least two of them, which are vertically fixed to the processing machine table by welding (e.g., ...). Figure 1 , 2 As shown, the lengths of the second vertical plates 31 are not uniform. Therefore, when the fixing plate 32 is fixed to the top of the second vertical plate 31, the fixing plate 32 is tilted, which facilitates the falling of the material bar under the action of gravity.

[0020] There are two fixing plates 32, which are fixed to the top of the second upright plate 31 by welding. Because the height of the second upright plate 31 is not uniform, the fixing plates 32 are tilted. The folding plate 33 is fixed to the top of the fixing plate 32 by welding, and the folding plate 33 is perpendicular to the fixing plate 32. The adjusting groove 38 is a rounded rectangle and runs through the folding plate 33. It is used to adjust the position of the side baffle 35 and improve the versatility of the equipment.

[0021] The bottom baffle 34 is fixed to the top of the folding plate 33 by welding and extends inward. The bottom baffle 34 is parallel to the fixing plate 32. Since the folding plate 32 is inclined relative to the ground, the bottom baffle 34 is also inclined. Figure 1 , 2 As shown, the bottom baffle 34 and the fixed plate 32 are connected by a folding plate 33, so there is space between the bottom baffle 34 and the fixed plate 32 to provide space for the installation of bolts.

[0022] The first extension plate 40 is integrally connected to one side of the bottom baffle 34, and the third extension plate 43 is integrally connected to the other side of the bottom baffle 34, with a smooth transition between the third extension plate 43 and the bottom baffle 34 to facilitate the rolling of the material bar. Figure 1-3 As shown, the first extension plate 40 is connected to the higher side of the bottom baffle 34, and the third extension plate 43 is connected to the lower side of the bottom baffle 34. By setting the first extension plate 40, the path of the material bar entering the material bar is extended, ensuring that enough material bars can be placed in the material trough 37. By setting the third extension plate 43, the material bars in the material trough 37 are guided to the material picking structure, facilitating subsequent clamping and transfer.

[0023] The side baffle 35 is adjustablely installed on the outside of the folding plate 33. When the material bar rolls downwards, the side baffle 35 abuts against both ends of the material bar to prevent it from shifting to the sides or even falling out. The fixing hole 39 passes through the side baffle 35 and mates with the adjusting groove 38. In actual installation, the fastening bolts are passed through the adjusting groove 38 and the fixing hole 39 in sequence, and the other end is tightened with a fastening nut to complete the installation of the side baffle 35 and the folding plate 33. (By setting the adjusting groove 38, the position of the side baffle 35 can be adjusted appropriately according to the diameter of the material bar, improving the versatility and installation flexibility of the equipment.)

[0024] The second extension plate 41 is integrally connected to one side of the side baffle 35 and cooperates with the first extension plate 40, such as Figure 2 , 3 As shown, the second extension plate 41 is perpendicular to the first extension plate 40 (the second extension plate 41 and the first extension plate 40 are not fixedly connected; the second extension plate 41 is fixedly connected to the side baffle 35, and the first extension plate 40 is fixedly connected to the bottom baffle 34). The material bar is placed on the first extension plate 40 and rolls down under the action of gravity. By setting the second extension plate 41, the two ends of the material bar are blocked to prevent the material bar from shifting from the sides or even falling out.

[0025] The fourth extension plate 44 is integrally connected to the other side of the side baffle 35 and cooperates with the third extension plate 43, such as Figure 2 , 3 As shown, (the fourth extension plate 44 and the third extension plate 43 are not fixedly connected; the fourth extension plate 44 is fixedly connected to the side baffle 35; and the third extension plate 43 is fixedly connected to the bottom baffle 34). During the falling process of the material bar, the fourth extension plate 44 is set to abut against both ends of the material bar, preventing the material bar from shifting from the sides or even falling out.

[0026] The top baffle 36 is fixed to the top of the side baffle 35 by welding and extends inward. The top baffle 36 is parallel to the bottom baffle 34, and a material trough 37 is formed between the bottom baffle 34, the side baffle 35, and the top baffle 36. Figure 1 , 2 As shown, the material bars are arranged in the material trough 37 and gradually roll downwards under the action of gravity. By setting the top baffle 36, the top of the material bars is limited to ensure that the material plates are arranged in a single layer in the material trough 37, and to prevent the material bars from squeezing each other and being squeezed out from the top when falling.

[0027] The feed plate 42 is integrally connected to the top baffle 36 on the side near the first extension plate 40. The feed plate 42 is arc-shaped, and the center of the arc of the feed plate 42 is away from the first extension plate 40. When the material bar on the first extension plate 40 rolls into the material trough 37, the arc-shaped feed plate 42 guides the material bar, facilitating its feeding.

[0028] like Figure 4-6As shown, the material handling structure includes a base plate 1, a receiving component, a transfer component, and a placement component. The base plate 1 is fixed to the processing machine table by screws. The receiving component, transfer component, and placement component are conveniently installed on the top of the base plate 1. The receiving component is used to receive single material bars rolling down from the material trough 37. The transfer component is used to clamp the material bars on the receiving component and transfer them to the placement component. Finally, the robot arm removes the material bars from the placement component and transfers them to the subsequent processing station for processing, thereby forming lead screws (such as grinding, polishing, cutting, thread rolling, etc.).

[0029] like Figure 7 As shown, the receiving assembly includes a second support column 19, a second support plate 20, a proximity switch 21, a transition plate 22, a material dropping section 23, a material supporting section 24, a material blocking section 25, a lifting cylinder 26, a lifting plate 27, a guide sleeve 28, a guide column 29, and a material lifting section 30. There are at least two second support columns 19, which are vertically fixed to the top of the base plate 1 by welding. The second support plate 20 is fixed to the top of the second support column 19 by welding.

[0030] At least two transition plates 22 are fixed to the top of the second support plate 20 by screws or welding and are spaced apart. These at least two transition plates 22 support the material bars rolling down into the material trough 37. A dropping section 23, a supporting section 24, and a blocking section 25 are sequentially provided on the top of the transition plates 22. The dropping section 23 is close to the feeding structure and is inclined; the supporting section 24 is arc-shaped and tangent to the dropping section 23; and the blocking section 25 is inclined and tangent to the supporting section 24. A top-feeding unit on one side of the second support plate 20 lifts a single material bar, which falls onto the arc-shaped supporting section 24 via the inclined dropping section 23. The inclined blocking section 25 prevents the material bar from rolling out from one side.

[0031] The guide sleeve 28 is embedded in the second support plate 20, and the guide post 29 vertically penetrates the guide sleeve 28 to improve the stability of the guide post 29's movement. The cylinder body of the lifting cylinder 26 is fixed to the top of the base plate 1 by screws, and the lifting plate 27 is fixed to the piston rod of the lifting cylinder 26 by welding. The lifting cylinder 26 drives the lifting plate 27 to move up and down. The guide post 29 is fixed to the top of the lifting plate 27. When the lifting cylinder 26 drives the lifting plate 27 to move up and down, it will drive the guide post 29 on the lifting plate 27 to move up and down synchronously.

[0032] The top section 30 is inclinedly formed at the top of the guide post 29 to lift the material bar and then push it onto the bottom section 23. Figure 7 , 8As shown, the material bar in the material trough 37 rolls onto the third extension plate 43 under the action of gravity. At this time, the material bar abuts against the side of the transition plate 22. The lifting cylinder 26 drives the guide column 29 to rise. The inclined material lifting part 30 pushes the foremost material bar to rise until it lands on the material dropping part 23. After the guide column 29 descends and resets, the second material bar continues to roll forward to the top of the guide column 29. This process is repeated to complete the feeding of a single material bar.

[0033] The proximity switch 21 is fixedly mounted on the second support plate 20 with its sensing end facing upwards, and is used to detect the material bar located on the transition plate 22. When the proximity switch 21 detects the material bar on the transition plate 22, it sends a detection signal to the PLC. After receiving the signal, the PLC controls the transfer component to perform a material picking action to remove the material bar (that is, when the proximity switch 21 detects the material bar and sends a signal to the PLC, the PLC controls the transfer component to perform the following actions in sequence according to the preset program: moving horizontally above the material bar, descending vertically to the gripping position, using a finger cylinder to grip and lift the material bar, and moving horizontally away from the transition plate).

[0034] The transfer assembly includes a first support column 2, a top plate 3, a slide rail 4, a slider 5, a linear module 6, a moving plate 7, a slide table mounting plate 8, a linear slide table 9, a lifting plate 10, a finger cylinder 11, a clamping plate 12, a clamping block 13, and a clamping part 14. The first support column 2 is vertically fixed to the top of the base plate 1 by welding, and the top plate 3 is fixed to the top of the first support column 2 by welding. The slide rail 4 is fixed to one side of the top plate 3 by screws, and the slider 5 is slidably mounted on the slide rail 4. By setting the slide rail 4 and slider 5 in a mutually cooperating manner, the stability of the reciprocating movement of the moving plate 7 is improved.

[0035] The linear module 6 is fixed to one side of the top plate 3 by screws and is parallel to the length direction of the slide rail 4. The movable plate 7 is fixed to the sliding part of the linear module 6 by screws, and the linear module 6 drives the movable plate 7 to move. The movable plate 7 is fixed to the side of the slider 5 away from the slide rail 4 by screws. When the linear module 6 drives the movable plate 7 to move, it will drive the slider 5 to move synchronously along the length direction of the slide rail 4.

[0036] The slide mounting plate 8 is fixed to the side of the movable plate 7 away from the linear module 6 by screws. The linear slide 9 is fixed to the slide mounting plate 8 by screws. The lifting plate 10 is connected to the linear slide 9, and the lifting plate 10 moves up and down by the linear slide 9. There are at least two finger cylinders 11, which are fixed to the bottom of the lifting plate 10 by screws and are spaced apart. The clamping plates 12 are fixed to the grippers of the finger cylinders 11 by screws. The finger cylinders 11 drive the two clamping plates 12 to move inward or open outward synchronously.

[0037] The clamping block 13 is integrally connected to the inner side of the clamping plate 12. The clamping part 14 is opened on the inner side of the clamping block 13 and the clamping part 14 is in the shape of "V". The clamping plate 12 is moved inward by the finger cylinder 11, thereby clamping a single bar on the transition plate 22.

[0038] The placement assembly includes a first upright plate 15, a first support plate 16, a bearing plate 17, and a bearing part 18. There are two first upright plates 15, which are vertically fixed to the top of the base plate 1 by welding. The first support plate 16 is fixed to the top of the two first upright plates 15 by welding. The bearing plate 17 is fixed to the top of the first support plate 16 by welding and is spaced apart.

[0039] The support part 18 is located on the top of the support plate 17 and is V-shaped. The transfer component picks up a single bar from the receiving component and transfers it to the support part 18. Finally, the robot arm removes the bar from the component and transfers it to the subsequent processing station for processing, thereby forming a lead screw (such as grinding, polishing, cutting, thread rolling, etc.).

They should not be construed as limiting the scope of protection of this utility model.
