DETAILED DESCRIPTION

[0051] 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.

[0052] like Figure 1-15 As shown, the present invention has the following four specific embodiments. Example 1

[0053] A drilling fastener device for parts processing includes a metal ring 100 and further includes:

[0054] A seat body 1, rollers 11 are fixedly connected at the four corners of the bottom of the seat body 1, a mounting cylinder 12 is fixedly connected inside the seat body 1, a step groove 13 is provided on the top of the mounting cylinder 12, and a turntable 14 is rotatably connected in the step groove 13;

[0055] A column 2, which is fixedly connected to the turntable 14 and symmetrically provided in pair, a lifting cylinder 21 is slidably sleeved on the column 2, and an escape hole 22 is opened on the upper part of one side of the column 2 away from the center of the turntable 14;

[0056] A drilling motor 3, which is slidably connected to the right side of the base body 1, and a drill bit 31 corresponding to the avoidance hole 22 is fixedly connected to the output shaft head of the drilling motor 3;

[0057] The upper bin 4 is fixedly connected with a support rod 41 on the left side of the base body 1, and the upper bin 4 is fixedly connected to the support rod 41. A loading tray 42 is rotatably connected in the upper bin 4, and a circular conveying groove 43 is symmetrically provided on the loading tray 42. A drop opening 44 corresponding to the conveying groove 43 is provided on the right side of the bottom plate of the upper bin 4, and a barrel 45 corresponding to the conveying groove 43 is fixedly connected to the left side of the top plate of the upper bin 4, and the metal rings 100 are stacked and placed in the barrel 45;

[0058] The power mechanism is used to drive the drilling motor 3 to move left and right, and the power mechanism is also used to drive the turntable 14 and the loading tray 42 to rotate;

[0059] The unloading mechanism, when the rotating disk 14 rotates, the unloading mechanism lifts up the lifting cylinder 21 to unload the metal ring 100 after drilling.

[0060] Furthermore, the conveying groove 43 is densely covered with balls 46 .

[0061] In this embodiment, Figure 1 and Figure 3 As shown, the metal rings 100 are stacked in the barrel 45, and the left and right conveying grooves 43 are aligned with the barrel 45 and the drop opening 44 respectively. Under the action of gravity, the metal ring 100 at the bottom of the barrel 45 falls into the conveying groove 43 on the left.

[0062] The two columns 2 are located on the left and right sides respectively. The column 2 on the left is aligned with the blanking opening 44 , and the column 2 on the right is facing the drill bit 31 . A metal ring 100 is sleeved on the column 2 on the left.

[0063] The power mechanism drives the drilling motor 3 to move left and right, and the drilling motor 3 drives the drill bit 31 to rotate. During the movement of the drilling motor 3 to the left, the metal ring 100 is drilled by the drill bit 31. When the head of the drill bit 31 enters the avoidance hole 22, the drilling process is completed, and then the drilling motor 3 moves to the right.

[0064] The power mechanism drives the loading tray 42 to rotate, and the loading tray 42 rotates 180° each time, so that the left and right conveying grooves 43 are swapped, and the conveying groove 43 containing the metal ring 100 is aligned with the drop opening 44. The metal ring 100 falls through the drop opening 44 and is sleeved on the left column 2. The empty conveying groove 43 rotates to a position aligned with the barrel 45 to receive the metal ring 100.

[0065] The provision of the ball bearings 46 allows the metal ring 100 to fall smoothly. In the present application, the thickness of the conveying groove 43 is consistent with the vertical height of the metal ring 100 .

[0066] The power mechanism drives the turntable 14 to rotate. When the turntable 14 rotates, the unloading mechanism lifts up the lifting cylinder 21 to unload the metal ring 100 after drilling. The turntable 14 rotates 180° each time, so that the left and right columns 2 are swapped, that is, the column 2 with the metal ring 100 is rotated to the right side for drilling, and the column 2 without the metal ring 100 is rotated to the left side to be re-aligned with the blanking port 44, and then the drilling motor 3 moves to the left to perform drilling. This cycle can realize continuous automated drilling. Example 2

[0067] The power mechanism includes a power motor 51, a sector gear 52, a first full gear 53 and a second full gear 54. A first shaft rod 55 is fixedly connected to the center of the loading disk 42. The first shaft rod 55 is rotatably connected to the loading bin 4 and the seat body 1. A second shaft rod 56 is fixedly connected to the center of the lower surface of the turntable 14. The second shaft rod 56 is rotatably connected to the bottom plate of the mounting cylinder 12. An L-shaped stand 57 is fixedly connected to the right side of the seat body 1. A track groove 58 is provided on the top plate of the stand 57. A track rod 59 is fixedly connected in the track groove 58. A track plate 510 slidably connected to the track rod 59 is provided in the track groove 58. A base 511 is fixedly connected to the top of the track plate 510. The drilling motor 3 is fixedly connected to the base. A bracket 512 is fixedly connected to the stand 57. The power motor 51 is fixedly connected to the bottom of the bracket 512. The output shaft of the power motor 51 is rotatably connected to the bracket 512 The sector gear 52 is fixedly connected to the output shaft of the power motor 51, and a pin shaft 513 is fixedly connected to the sector gear 52 and the track plate 510, and a connecting rod 514 is hinged between the two pin shafts 513. The front and rear sides of the sector gear 52 are rotatably connected with the first rotating shaft 515 and the second rotating shaft 516 respectively. The first full gear 53 and the second full gear 54 are respectively fixedly connected to the top of the first rotating shaft 515 and the second rotating shaft 516, and the first rotating shaft 515 and the first shaft rod 55 are fixedly connected to the bottom of the first rotating shaft 515 and the first shaft rod 55. The two first transmission wheels 517 are linked by a first belt 518, and the second rotating shaft 516 and the bottom of the second shaft rod 56 are fixedly connected to the second transmission wheel 519, and the two second transmission wheels 519 are linked by a second belt 520. The number of teeth of the sector gear 52 is equal to half of the number of teeth of the first full gear 53 and the second full gear 54.

[0068] Furthermore, the teeth on the sector gear 52 are distributed within a range smaller than 180°.

[0069] In this embodiment, the specific technical features of the power mechanism are disclosed, such as Figure 1-3 As shown, when the power motor 51 is working, it drives the sector gear 52 to rotate, and the sector gear 52 drives the track plate 510, the machine base 511 and the drilling motor 3 to move through the connecting rod 514.

[0070] The sector gear 52 drives the first full gear 53 and the second full gear 54 to rotate alternately.

[0071] When the first full gear 53 rotates, it drives the first rotating shaft 515 and one of the first transmission wheels 517 to rotate. Under the action of the first belt 518, the other first transmission wheel 517 and the first shaft 55 rotate, so that the loading tray 42 rotates.

[0072] When the second full gear 54 rotates, it drives the second rotating shaft 516 and one of the second transmission wheels 519 to rotate. Under the action of the second belt 520, the other second transmission wheel 519 and the second shaft 56 rotate, so that the rotating disk 14 rotates.

[0073] Since the number of teeth of the sector gear 52 is equal to half of the number of teeth of the first full gear 53 and the second full gear 54, the loading tray 42 and the rotating disk 14 rotate 180 degrees each time.

[0074] like Figure 5 As shown, in the initial state, the teeth and the pin 513 on the sector gear 52 face right, and the sector gear 52 rotates clockwise. During the rotation of 180° by the sector gear 52 (i.e., from ① to ②), the drilling motor 3 is driven to move to the left to complete the drilling operation, and the first full gear 53 and the loading plate 42 are driven to rotate 180° to complete the loading. During the rotation of 180° by the sector gear 52 again (i.e., from ② to ①), the drilling motor 3 moves to the right, and the second full gear 54 rotates 180° counterclockwise, and the unloading is completed in this process.

[0075] That is, when the drilling motor 3 moves to the left, the drilling operation is completed and the loading is completed; when the drilling motor 3 moves to the right, the unloading is completed during the rotation of the turntable 14. Since the teeth on the sector gear 52 are distributed within an interval less than 180°, such as Figure 5 As shown, when the drilling motor 3 starts to move to the right, the turntable 14 first remains stationary so that the drill bit 31 can be pulled out of the avoidance hole 22 and separated from the metal ring 100. After the drilling motor 3 moves a certain distance to the right, the turntable 14 starts to rotate. During this process, the unloading mechanism works to complete the unloading. Example 3

[0076] The unloading mechanism includes a first driving groove 61 and a first driving shaft 62. A cover ring 63 is fixedly connected to the top of the installation cylinder 12. The first driving groove 61 is opened on the inner wall of the cover ring 63. The first driving shaft 62 is fixedly connected to the lower part of the outer wall of the jacking cylinder 21.

[0078] The first driving groove 61 includes a first falling groove 6101, a first lifting groove 6102 and a first bottom groove 6103; the first falling groove 6101 is opened on the rear side of the cover ring 63, the first lifting groove 6102 is located on the right side of the first falling groove 6101, and the top of the first lifting groove 6102 is connected to the top of the first falling groove 6101, and the two ends of the first bottom groove 6103 are connected to the bottom of the first falling groove 6101 and the first lifting groove 6102 respectively.

[0079] Furthermore, a collecting box 68 is fixedly connected to the rear side of the cover ring 63, a U-shaped baffle 69 is fixedly connected to the top of the collecting box 68, a blower 610 is fixedly connected to the upper bin 4, an outlet of the blower 610 is fixedly connected to an air outlet pipe 611, a head of the air outlet pipe 611 is fixedly connected to a tee 612, and the other two interfaces of the tee 612 are fixedly connected to an injection pipe 613, and the head of the injection pipe 613 faces the rear side.

[0080] Furthermore, a vertical plate 71 is fixedly connected to the rear side of the bottom plate of the mounting tube 12, and a pair of slide grooves 72 are opened on the front side of the vertical plate 71. A metal block 73 is slidably connected in the slide groove 72, and a spring telescopic rod 74 is fixedly connected between the metal block 73 and the bottom of the slide groove 72. The power connecting wire 75 of the metal block 73 extends out of the vertical plate 71, and a support rod 76 is symmetrically fixedly connected to the bottom of the turntable 14. A metal plate 77 is fixedly connected to the bottom of the support rod 76. The position of the metal plate 77 corresponds to the position of the column 2. The two sides of the metal plate 77 are inclined. A control switch 78 is fixedly connected to the front side of the seat body 1, and also includes an external power supply 79. One pole of the external power supply 79 is connected to the drilling motor 3, the power motor 51, and one of the terminals of the blower 610 through the control switch 78, and the other pole of the external power supply 79 is connected to the drilling motor 3, the other terminal of the power motor 51 and one of the metal blocks 73. The other terminal of the blower 610 is electrically connected to another metal block 73.

[0081] In this embodiment, the technical features of the unloading mechanism are disclosed, such as Figure 3 as well as Figure 6-7 As shown, when the turntable 14 rotates, the first drive shaft 62 slides in the first drive groove 61, and the first drive shaft 62 slides up and down through the first drive groove 61, thereby driving the lifting cylinder 21 to move.

[0082] like Fig.13 As shown, with the angle of the cover ring 63 as the horizontal coordinate, and the initial point of the horizontal coordinate is on the right side, and the angle increases continuously in the counterclockwise direction, and the height of the first driving groove 61 as the vertical coordinate, a distribution diagram of the first driving groove 61 in the two-dimensional space is made. Fig.13 The thin solid line in represents the distribution diagram of the first driving slot 61 in the two-dimensional space. In the figure, A1 and A2 represent the first driving shaft 62 on the right side and the first driving shaft 62 on the left side, respectively.

[0083] When the turntable 14 drives the column 2 to rotate 180° counterclockwise, A1 first slides in the first bottom groove 6103, and after rotating a certain angle, A1 enters the first lifting groove 6102, and the height of A1 and the lifting cylinder 21 is increased. When the lifting cylinder rises, the metal ring 100 after drilling is lifted. When A1 moves to the top of the first drop groove 6101 at 90°, it is reset under the action of the first spring 67, and the lifting cylinder 21 descends until it moves to the position of 180°. At this time, A1 is aligned with the blanking port 44. A2 switches positions with A1 and moves to the right side facing the drill bit 31.

[0084] In the present application, a first spring 67 is provided. When the bottom of the lifting cylinder 21 contacts the turntable 14, the first spring 67 is in a natural state. When the height of the lifting cylinder 21 rises, the first spring 67 is compressed. When the first driving shaft 62 moves to the top of the first drop groove 6101, the first spring 67 is released, causing the first driving shaft 62 and the lifting cylinder 21 to descend and reset.

[0085] like Figure 1 As shown, the blower 610 is working, blowing out high-speed gas from the gas outlet pipe 611 and the gas injection pipe 613 . When the lifting cylinder 21 lifts up the drilled metal ring 100 , the high-speed gas blows the metal ring 100 into the collection box 68 .

When the metal plate 77 moves to the position of the metal block 73, the two metal blocks 73 are connected, as shown in FIG. Figure 8 As shown, the metal blocks 73 are connected by a spring telescopic rod 74 , and the two sides of the metal plate 77 are tilted. When the metal plate 77 moves to the position of the metal blocks 73 , the two metal blocks 73 can be in close contact with the metal plate 77 .

[0087] like Fig. 9 As shown, when the device is working, the control switch 78 is closed, the drilling motor 3 and the power motor 51 are working, and when the metal plate 77 contacts the two metal blocks 73, the blower 610 works, that is, when the metal ring 100 after drilling moves to the rear side, the lifting cylinder 21 lifts it up, and the blower 610 works to blow it into the collection box 68.

The two ends of the second spring 85 are respectively fixedly connected to the piston disc 82 and the turntable 14. A through hole 86 is provided on the turntable 14 at a position corresponding to the cavity 81. A second driving groove 87 is provided on the inner wall of the mounting cylinder 12. A second driving shaft 88 is fixedly connected to the bottom of the push rod 84, and the second driving shaft 88 is slidably connected in the second driving groove 87.

[0089] A main flow channel 89 is provided above the column 2, the bottom of the main flow channel 89 is communicated with the cavity 81, two groups of secondary flow channels 810 are provided on the side wall of the main flow channel 89, the avoidance hole 22 is located between the two groups of secondary flow channels 810, a circular hole 811 is provided in the middle of the secondary flow channel 810, a piston column 812 is sealingly and slidably connected in the circular hole 811, a fixed column 813 is fixedly connected to the side of the piston column 812 away from the main flow channel 89, and the diameter of the fixed column 813 is smaller than the diameter of the secondary flow channel 810, and hydraulic oil 814 is contained in the cavity above the piston plate 82 and in the main flow channel 89;

[0090] The second driving groove 87 includes a second top groove 8701, a second falling groove 8702, a second lifting groove 8703 and a second bottom groove 8704; the second top groove 8701 is located on the right side, the rear end of the second top groove 8701 is connected to the top of the second falling groove 8702, the front end of the second top groove 8701 is connected to the top of the second lifting groove 8703, and the second lifting groove 8703 is connected to the bottom of the second falling groove 8702 through the second bottom groove 8704.

[0091] Furthermore, the first lifting grooves 6102 are distributed within a range of 45°, the second top grooves 8701 are distributed within a range of 60°, and the second lifting grooves 8703 are distributed within a range of 120°.

[0092] In this embodiment, in order to prevent the metal ring 100 from being misplaced during drilling, the metal ring 100 is fixed during drilling. Figure 6-7 as well as Figure 10-12 As shown, when the column 2 moves to the right, the second drive shaft 88 is located in the second top groove 8701, the drive shaft is located at the high point, and the push rod 84 and the piston plate 82 are lifted up, the hydraulic oil 814 is squeezed into the secondary flow channel 810, and the piston column 812 and the fixed column 813 are pushed outward, and the metal ring 100 is fixed by the fixed column 813.

[0093] like Fig.13As shown, with the angle of the mounting tube 12 as the horizontal coordinate, the initial point of the horizontal coordinate is on the right side, and the angle increases continuously in the counterclockwise direction, and the height of the second driving groove 87 as the vertical coordinate, a distribution diagram of the second driving groove 87 in the two-dimensional space is made. Fig.13 The thick solid line in represents the distribution diagram of the second driving slot 87 in the two-dimensional space. In the figure, B1 and B2 represent the second driving shaft 88 on the right side and the second driving shaft 88 on the left side, respectively.

[0094] B1 is first in the second top groove 8701, and the metal ring 100 on the right is fixed. After drilling is completed, the turntable 14 rotates counterclockwise. After rotating a certain angle, B1 descends in the second drop groove 8702 through the action of the second spring 85, and the fixation of the metal ring 100 is released. B2 is first in the column 2 on the left side of 180° to receive the new metal ring 100, and then B2 enters the second lifting groove 8703 and rises to fix the metal ring 100. When the undrilled metal ring 100 moves to the right, B2 is in the second top groove 8701, and the fixing force of the metal ring 100 is the largest.

[0095] We cooperate with the unloading mechanism to provide a comprehensive explanation.

[0096] After the metal ring 100 on the right is drilled, there is an undrilled metal ring 100 on the left column 2 .

[0097] When the turntable 14 rotates 30°, B1 descends, the metal ring 100 after drilling is released, and B2 enters the second lifting groove 8703, and the metal ring 100 without drilling begins to be fixed;

[0098] When the turntable 14 rotates 45°, the metal ring 100 after drilling is released, and A1 begins to enter the first lifting groove 6102. The lifting cylinder 21 lifts the metal ring 100 after drilling, and the blower 610 can blow the lifted metal ring 100 into the collection box 68.

[0099] When the turntable 14 rotates 90°, A1 moves to the top of the first drop groove 6101 and quickly drops into the first bottom groove 6103 .

[0100] When the turntable 14 rotates 150°, B2 enters the second top groove 8701, and the undrilled metal ring 100 has the maximum fixing force.

[0101] When the rotating disk 14 rotates 180°, A1 and A2 are switched, and B1 and B2 are switched.

[0102] The working principle of the present invention is:

[0103] In the initial state, a metal ring 100 is sleeved on the right column 2 .

[0104] The drilling motor 3 drives the drill bit 31 to rotate. When the power motor 51 works, it first drives the sector gear 52 to rotate 180° clockwise. The drilling motor 3 moves to the left to drill the metal ring 100. In this process, the sector gear 52 drives the first full gear 53 to rotate 180°. The loading plate 42 rotates 180°, and the left column 2 is covered with an undrilled metal ring 100.

[0105] Then the sector gear 52 continues to rotate 180°, the drilling motor 3 moves to the right, the drill bit 31 is pulled out of the avoidance hole 22 and separated from the metal ring 100, and then the sector gear 52 drives the second full gear 54 and the turntable 14 to rotate 180°. At this time:

[0106] The column 2 on the right side rotates, and the second drive shaft 88 on the right side first descends in the second drop groove 8702, and the drilled metal ring 100 is released, and then the first drive shaft 62 on the right side rises in the first lifting groove 6102 to lift the drilled metal ring 100. When it approaches the rear side, the blower 610 is powered on to blow the drilled metal ring 100 into the collecting box 68, and then the column 2 continues to rotate to the left. At this time, the lifting cylinder 21 and the piston disk 82 are at the low point, which is convenient for subsequent loading.

[0107] When the left column 2 rotates counterclockwise, the left first drive shaft 62 is always located in the first bottom groove 6103, the lifting cylinder 21 is at the low point, and the undrilled metal ring 100 rotates with the left column 2. When the second drive shaft 88 enters the second lifting groove 8703, the piston disk 82 rises, and the fixing column 813 pushes out to fix the undrilled metal ring 100 until the left column 2 rotates to the right, the second drive shaft 88 is located in the second top groove 8701, and the undrilled metal ring 100 is subjected to the maximum fixing force.

[0108] Then the drilling motor 3 continues to move to the left, and the cycle is repeated to realize the automatic continuous drilling of the metal ring 100. It is only necessary to continuously add the metal ring 100 into the barrel 45.
