DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 The present invention provides a technical solution: an automatic screw drilling device, comprising a frame 1, a punching assembly 2 for drilling holes in the screw is arranged on the right part of the frame 1, a loading assembly 3 is arranged on the top of the frame 1, an electric three-jaw chuck 4 for clamping the screw is fixedly connected to the middle part of the right side of the frame 1, the loading assembly 3 comprises a stacking rack 31 fixedly connected to the front and rear ends of the top of the inner side of the frame 1, a rotating shaft 32 is arranged below the stacking rack 31, and the left and right sides of the rotating shaft 32 are rotatably connected to the frame 1, the loading assembly 3 also comprises a first motor 33 arranged on the left side of the frame 1, the output shaft of the first motor 33 passes through the left part of the frame 1 and is fixedly connected to the rotating shaft 32, and the outer wall of the rotating shaft 32 is fixedly connected with a drop wheel 34 on both sides, and the ring side of the two drop wheels 34 is provided with a concave hole 35, which is in The outer walls of the front end stacking rack 31 are fixedly connected with guide arcs 36 on both sides, the left side of the frame 1 is provided with a pushing assembly 5 for pushing the screw toward the electric three-jaw chuck 4, the inner rear end of the frame 1 is fixedly connected with a long plate 11, the front ends of the long plate 11 are fixedly connected with limiting plates 12 on both sides, the front end of the limiting plate 12 is rotatably connected with a stop plate 13, the punching assembly 2 includes an L-shaped frame 21 fixedly connected to the right side of the frame 1, the right side of the L-shaped frame 21 is fixedly connected with an electric telescopic rod 22, the output shaft of the electric telescopic rod 22 passes through the L-shaped frame 21 and is fixedly connected to a second motor 23, and the output shaft of the second motor 23 is fixedly installed with a drill bit 24.

[0022] By adopting the above-mentioned technical scheme, the stacking racks 31 at the front and rear ends jointly constitute a stacking space. Before processing, the screw rod is placed in the stacking space jointly constituted by the stacking racks 31, and the two ends of the screw rod are in contact with the inner wall of the frame 1. It should be noted that the bottom opening of the stacking space formed by the two stacking racks 31 is relatively small, and only one screw rod can be dropped at a time.

[0023] During processing, the output shaft of the first motor 33 rotates, causing the rotating shaft 32 to rotate with the two falling wheels 34. When the concave hole 35 is not at the bottom opening of the stacking space formed by the two stacking racks 31, the falling wheels 34 hinder the screw rod in the stacking rack 31 from falling. When the concave hole 35 is located at the bottom opening of the stacking space formed by the two stacking racks 31, the screw rod at the bottom of the stacking space falls, so that the screw rod falls to the position of the concave hole 35. Subsequently, the output shaft of the first motor 33 rotates, thereby changing the position of the concave hole 35 and the screw rod. When the position of the concave hole 35 is in an inclined state, the screw rod moves down under the action of gravity. The screw rod falls on the guide arc 36 and continues to fall along the guide arc 36. When the screw rod is limited by the stop plate 13 installed on the limiting plate 12 when falling, the screw rod is just in a position close to the electric three-jaw chuck 4. At this time, the screw rod is pushed by the pushing component 5 to facilitate the right end of the screw rod to be inserted into the interior of the electric three-jaw chuck 4. At this time, the electric three-jaw chuck 4 is controlled to start clamping the screw rod. During the clamping process, the three clamping clamps of the electric three-jaw chuck 4 clamp the screw rod in the middle part of the electric three-jaw chuck 4, thereby realizing the positioning of the screw rod. After clamping, the center hole at the end of the screw rod can be punched by the punching component 2.

[0024] Such a design can realize the function of automatically placing the screw rod accurately in the predetermined processing area, and can conveniently and quickly complete the positioning of the screw rod, thus improving the efficiency of the screw rod drilling processing.

[0025] When drilling, the output shaft of the electric telescopic rod 22 installed on the L-shaped frame 21 is extended, so that the second motor 23 and the drill bit 24 are close to the right end face of the screw rod, and the output shaft of the second motor 23 rotates, so that the drill bit 24 rotates and cooperates with the output shaft of the electric telescopic rod 22 to slowly extend, thereby facilitating drilling of the right end face of the screw rod, so that the side center hole of the screw rod can be drilled.

[0026] Specifically, Figures 1 to 3 As shown, the pushing assembly 5 includes a push plate 51 slidably connected to the left side of the frame 1, a bent frame 52 is fixedly connected to the left side of the push plate 51, a tilting block 53 is fixedly connected to the top of the bent frame 52, the left side of the tilting block 53 is tilted, the front and rear ends of the left side of the frame 1 are fixedly connected to mounting frames 9, the sides of the two mounting frames 9 that are close to each other are commonly fixedly connected to the first motor 33, the pushing assembly 5 also includes an extrusion frame 54 fixedly connected to the outer wall of the output shaft of the first motor 33, a straight rod 56 is fixedly connected to the right side of the tilting block 53, the right side of the straight rod 56 is slidably connected to the frame 1, and a first spring 55 is fixedly connected between the tilting block 53 and the frame 1.

[0027] By adopting the above technical solution, the mounting frame 9 is used to fix the first motor 33. After the screw rod falls into the recessed hole 35, as the output shaft of the first motor 33 rotates, when the screw rod falls onto the guide arc 36 and is limited by the stop plate 13, the bent frame 52 just moves to the inclined position close to the tilting block 53, and the output shaft of the first motor 33 continues to rotate, so that the bent frame 52 squeezes the inclined surface of the tilting block 53, so that the tilting block 53 and the squeezing frame 54 move to the right, thereby causing the push plate 51 to move to the right and push the screw rod, so that the right end part of the screw rod is pushed into the interior of the electric three-jaw chuck 4, further facilitating the loading and positioning of the screw rod, thereby improving the processing efficiency.

[0028] When the tilting block 53 moves to the right, the straight rod 56 also moves to the right, and the first spring 55 is compressed at this time. As the output shaft bent frame 52 of the first motor 33 continues to rotate, the bent frame 52 rotates away from the tilting block 53. Under the elastic force of the first spring 55, the push plate 51, the extrusion frame 54 and the tilting block 53 are reset.

[0029] It should be noted that when drilling, the bending frame 52 maintains the extrusion limit on the inclined block 53. When punching, the push plate 51 can support the left end face of the screw rod, and can cooperate with the electric three-jaw chuck 4 to position and fix the screw rod, so that the clamping during processing is more stable to ensure the accuracy of the punching process.

[0030] It should be noted that the rotation speed of the first motor 33 is relatively slow, and when the bending frame 52 approaches the tilting block 53 next time, the tilting block 53 has been completely reset.

[0031] Specifically, Figure 1 and Figures 4 to 7 As shown, an opening and closing assembly 6 is arranged below the stacking rack 31, and the opening and closing assembly 6 includes a fixed cylinder 61 fixedly connected to the front end of the limiting plate 12 and close to the side of the falling wheel 34, a first piston plate 62 is arranged inside the fixed cylinder 61, a small frame 63 is fixedly connected to the top of the first piston plate 62, a roller 64 is rotatably connected to the top of the small frame 63, a cylinder 65 is fixedly connected to the bottom front end of the limiting plate 12, a second piston plate 66 is arranged inside the cylinder 65, a moving rod 67 is fixedly connected to the front end of the moving rod 67, a moving block 68 is rotatably connected to the front end of the moving rod 67, and the outer wall of the moving block 68 is slidably connected to the stop plate 13, a pipe 610 is fixedly inserted between the fixed cylinder 61 and the cylinder 65, a second spring 69 is fixedly connected between the top of the first piston plate 62 and the fixed cylinder 61, the outer side of the first piston plate 62 fits the inner wall of the fixed cylinder 61, and the outer side of the second piston plate 66 fits the inner side of the cylinder 65.

[0032] By adopting the above technical solution, when the punching is completed, the output shaft of the first motor 33 rotates, so that the bending frame 52 moves away from the tilting block 53, the push plate 51 is reset, and the claws of the electric three-jaw chuck 4 are screwed. At this time, as the output shaft of the first motor 33 continues to rotate, when the recessed hole 35 rotates to the bottom position, the first piston plate 62 slides upward inside the fixed cylinder 61 under the elastic force of the second spring 69, so that the small frame 63 moves upward, so that the top of the roller 64 is against the area at the recessed hole 35. It should be noted that the interior of the fixed cylinder 61 and the cylinder 65 is provided with a liquid medium, and the liquid medium can be water. When the small frame 63 moves upward, Part of the medium in the cylinder 65 enters the fixed cylinder 61 through the pipe 610. Under the action of negative pressure, the second piston plate 66 moves away from the stop plate 13, so that the moving rod 67 moves, which makes it easier for the angle of the stop plate 13 to change. At this time, the moving block 68 slides on the stop plate 13, so that the moving rod 67 and the moving block 68 rotate relative to each other, so that the stop plate 13 can rotate, so that the stop plate 13 does not block the screw rod, so that under the action of the gravity of the screw rod, the screw rod falls on the slide-out frame 14 fixed on the long plate 11, and slides out along the slide-out frame 14, thereby realizing the function of automatic discharging and further improving the efficiency of drilling processing.

[0033] It should be noted that the elastic force of the second spring 69 is large enough to move the first piston plate 62 and the second piston plate 66, and the design of the roller 64 is conducive to reducing the friction during movement. When the outer wall of the roller 64 is in contact with the outer wall of the drop wheel 34 and is not located in the area of ​​the recessed hole 35, the second spring 69 is in a compressed state. When the screw rod falls on the stop plate 13, the outer wall of the roller 64 contacts the outer wall of the drop wheel 34, so that when the small frame 63 moves upward, it is ensured that the screw rod cannot pass through at this time.

[0034] Specifically, Figure 4 and Figure 5 As shown, a deceleration assembly 7 is provided on the side away from each other of the two falling wheels 34, and the deceleration assembly 7 includes a blocking arc plate 71 fixedly connected to the bottom of the stacking rack 31 at the rear end, and a limiting arc plate 72 is fixedly connected to the bottom of the blocking arc plate 71, and an elastic sheet 73 is fixedly connected to the side of the limiting arc plate 72 close to the guide arc 36.

[0035] By adopting the above technical solution, when the screw rod falls from the recessed hole 35, the blocking arc plate 71 plays a limiting role to ensure that the screw rod passes between the limiting arc plate 72 and the guide arc 36. The elastic sheet 73 is made of a metal material with elastic force, and its elastic force is less than the gravity of the screw rod. When the screw rod reaches the position of the elastic sheet 73, the elastic sheet 73 is deformed by the impact of the falling screw rod and the gravity. At this time, the screw rod passes through, which can reduce the impact of the screw rod on the stop plate 13 when it falls, reduce the possibility of damage to this part due to the impact, and thus extend the service life of the device.

[0036] Specifically, Figures 1 to 5 As shown, both sides of the bottom of the long board 11 are fixedly connected with a slide-out frame 14, the bottom of the slide-out frame 14 is tilted, and the bottom of the slide-out frame 14 is elastic, the left side of the electric three-jaw chuck 4 is fixedly connected with a guide cover 15, and the bottom surfaces of the two slide-out frames 14 are commonly fixedly connected with a lifting plate 16, both ends of the lifting plate 16 are slidably connected to the frame 1, the left side of the lifting plate 16 passes through the frame 1 and is fixedly connected to a limiting block 17, the left side of the limiting block 17 is tilted, the left bottom of the push plate 51 is fixedly connected with a limiting bending plate 10, the outer wall of the limiting bending plate 10 is close to the limiting block 17 and fits with the inclined surface of the limiting block 17, the front end of the frame 1 is fixedly connected with an obstruction frame 18, and a third spring 8 is fixedly connected between the bottom of the lifting plate 16 and the frame 1, and the elastic force of the third spring 8 is greater than the gravity of the screw rod.

[0037] By adopting the above technical solution, two guide covers 15 are provided, and the two guide covers 15 form a trumpet-shaped through groove, and the width of the area at the bottom of the channel is slightly larger than the diameter of the screw rod. When the stop plate 13 does not block the screw rod and the screw rod falls, under the action of the guide cover 15, the angle deviation of the screw rod when it falls can be reduced, thereby easily causing the screw rod to pile up unevenly when the material is dropped.

[0038] A storage box for storing the screw after drilling can be designed below the obstruction rack 18. When the screw falls on the slide-out rack 14, it will be blocked by the obstruction rack 18 until the push plate 51 pushes the screw to be processed next time. Since the push plate 51 moves to the right, the limiting bending plate 10 moves accordingly, so that the limiting bending plate 10 squeezes the limit block 17 so that the lifting plate 16 overcomes the elastic force of the third spring 8 and moves downward, so that the bottom of the slide-out rack 14 bends, which makes it easier for the screw to be discharged from here and fall into the storage box for storing the screw. When blocked by the obstruction rack 18, the screw is in a parallel state with the front end of the obstruction rack 18, so that the screw falls more neatly into the storage box when it falls.

[0039] It should be noted that the elastic force of the third spring 8 is relatively small, only slightly greater than the gravity of the screw rod, and the lifting plate 16 is made of rigid material. When the limiting bending plate 10 squeezes the inclined part of the limit block 17, it is sufficient to move the lifting plate 16 downward.

[0040] Working principle: The screw rod is placed in the stacking space formed by the stacking racks 31, and the two ends of the screw rod are in contact with the inner wall of the frame 1. The output shaft of the first motor 33 rotates, so that the rotating shaft 32 rotates with the two drop wheels 34. When the concave hole 35 is not at the bottom opening of the stacking space formed by the two stacking racks 31, the drop wheels 34 prevent the screw rod in the stacking rack 31 from falling. When the concave hole 35 is located at the bottom opening of the stacking space formed by the two stacking racks 31, the screw rod at the bottom of the stacking space falls, so that the screw rod falls to the position of the concave hole 35. Then the output shaft of the first motor 33 rotates, thereby changing the position of the concave hole 35 and the screw rod. When the position of the recessed hole 35 is in an inclined state, the screw rod falls under the action of gravity, so that the screw rod falls on the guide arc 36 and continues to fall along the guide arc 36. When the rod falls, it is limited by the stop plate 13 installed on the limiting plate 12. The screw rod is just in a position close to the electric three-jaw chuck 4, and the output shaft of the first motor 33 continues to rotate, so that the bending frame 52 squeezes the inclined surface of the tilting block 53, so that the tilting block 53 and the squeezing frame 54 move to the right, so that the push plate 51 moves to the right and pushes the screw rod, so that the right end part of the screw rod enters the interior of the electric three-jaw chuck 4, which further facilitates the small material positioning of the screw rod, thereby improving the processing efficiency.

[0041] When the punching is completed, the output shaft of the first motor 33 rotates, so that the bending frame 52 moves away from the tilting block 53, the push plate 51 is reset, and the claws of the electric three-jaw chuck 4 are screwed. At this time, as the output shaft of the first motor 33 continues to rotate, when the recessed hole 35 rotates to the bottom position, the first piston plate 62 slides upward inside the fixed cylinder 61 under the elastic force of the second spring 69, so that the small frame 63 moves upward, so that the top of the roller 64 is against the area at the recessed hole 35. It should be noted that the interior of the fixed cylinder 61 and the cylinder 65 is provided with a liquid medium, and the liquid medium can be water. When the small frame 63 moves upward, the cylinder 65 Part of the medium inside enters the fixed cylinder 61 through the pipe 610. Under the action of negative pressure, the second piston plate 66 moves away from the stop plate 13, so that the moving rod 67 moves, which makes it easier for the angle of the stop plate 13 to change. At this time, the moving block 68 slides on the stop plate 13, so that the moving rod 67 and the moving block 68 rotate relative to each other, so that the stop plate 13 can rotate, so that the stop plate 13 does not block the screw rod, so that under the action of the gravity of the screw rod, the screw rod falls on the sliding frame 14 fixed on the long plate 11, and slides out along the sliding frame 14, thereby realizing the function of automatic discharging, and further improving the efficiency of drilling processing.

[0042] When the screw rod falls from the recessed hole 35, the blocking arc plate 71 plays a limiting role to ensure that the screw rod passes between the limiting arc plate 72 and the guide arc 36. The elastic sheet 73 is made of a metal material with elastic force, and its elastic force is less than the gravity of the screw rod. When the screw rod reaches the position of the elastic sheet 73, the elastic sheet 73 is deformed by the impact of the falling screw rod and the gravity. At this time, the screw rod passes through, which can reduce the impact of the screw rod on the stop plate 13 when it falls, reduce the possibility of damage to this part due to the impact, and thus extend the service life of the device.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
