DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Example 1: See Figure 1-3 As shown, a drilling component includes a head 1, a drilling portion 2 mounted on the head 1, and a first driving portion 3 driving the drilling portion 2 to rotate on the head 1, and a second driving portion 4 driving the drilling portion 2 to move vertically on the head 1, the second driving portion 4 being mounted on the head 1 via a bracket 5;

[0029] The bracket 5 includes a bottom plate 6, a top plate 7 and a plurality of connecting rods 8. The bottom plate 6 is installed on the bottom surface of the machine head 1 outside the drilling part 2. The top plate 7 is arranged above the machine head 1 and directly above the bottom plate 6. The plurality of connecting rods 8 connect the top plate 7 and the bottom plate 6. The second driving part 4 is installed on the top plate 7. The driving end of the second driving part 4 is rotatably connected to the top of the drilling part 2.

[0030] In the present invention, the first driving part includes a motor and a belt, the motor is installed on the rear side of the machine head, the drilling part is installed on the front side of the machine head, the output shaft of the motor is connected to the drilling part via a belt, and the drilling part is driven to rotate by the motor and the belt, wherein a drill bit is installed at the bottom of the drilling part, and the drill bit can be driven to rotate by the first driving part for drilling the product. The second driving part adopts a driving cylinder, which is an air cylinder, an oil cylinder or an electric cylinder, and can be a mechanism that can drive the drilling part to move up and down. Of course, the second driving part can also include a driving motor, a screw, a slider and a guide rod, the guide rod is arranged parallel to the side of the screw, the screw and the guide rod are parallel to the vertical movement direction of the drilling part, one end of the slider is slidably arranged on the guide rod, and the other end is screwed to the screw, and the top of the drilling part is connected to the slider. When the driving motor drives the screw to rotate, it drives the slider to move vertically along the guide rod and drives the drilling part to move vertically on the machine head. The first driving part is fixedly mounted on the machine head, and the second driving part is directly fixed to the machine head through a bracket. The positions of the first driving part and the second driving part will not move, which can effectively ensure the processing accuracy of the drilling part on the product. Since the first driving part and the second driving part do not move, the corresponding connection line layout is also convenient, and the line does not need to be moved, so the line can be better protected.

[0031] The bracket adopts a structure of a bottom plate, a top plate and multiple connecting rods. The bottom plate is directly installed on the bottom surface of the machine head, and the top plate is arranged above the machine head. The top plate is connected to the bottom plate through connecting rods. In this structure, the original semi-automatic drilling equipment can be directly improved. The bracket and the second drive unit can be directly installed on the original machine head, so that the original equipment can be quickly improved and the modification cost can be reduced. There is no need to use new equipment, and it will not occupy more other space on the plane. It only needs to increase the height space occupied by the machine head to a certain extent, and the modification cost is also low.

[0032] See also Figure 1-3 As shown, a partition plate 9 and a positioning plate 10 are further provided between the machine head 1 and the top plate 7. The partition plate 9 is provided above the positioning plate 10. The partition plate 9 is fixedly connected to the connecting rod 8, and the positioning plate 10 is slidably connected to the connecting rod 8.

[0033] The positioning plate 10 is provided with a first hole, the partition plate is provided with a second hole, and a connecting block 11 is further provided between the partition plate 9 and the positioning plate 10. The second driving portion 4 is rotatably connected to the top of the drilling portion 2 via the connecting block 11. In this embodiment, the top of the drilling portion passes through the first hole and is rotatably connected to the connecting block, and the driving end of the second driving portion passes through the second hole and is connected to the connecting block. Of course, the top of the drilling portion can also be fixedly connected to the connecting block, and the driving end of the second driving portion can be rotatably connected to the connecting block.

[0034] Among them, a bearing is provided in the connecting block, the driving end of the second driving part is connected to a bearing above, and the top of the drilling part is detachably connected to the connecting block. Therefore, when the first driving part drives the drilling part to rotate, the connecting block will not rotate with it. The connecting block is used to rotatably connect the driving end of the second driving part to the top of the drilling part.

[0035] See also Figure 1 、 2 As shown, the diameters of the first hole and the second hole are both smaller than the width of the connecting block 11, and a third driving part 12 is installed on the partition 9. The driving end of the third driving part 12 is connected to the positioning plate 10, and the third driving part 12 drives the positioning plate 10 to move closer to or away from the top of the machine head 1.

[0036] The diameters of the first and second holes are smaller than the width of the connecting block. A third drive unit is also separately provided to drive the positioning plate up and down, so that the positioning plate moves closer to or further away from the top of the machine head, closer to or further away from the partition. Therefore, it is possible to drill at the fastest speed according to the required drilling depth of the desired product, or to ensure the drilling quality and not to drill too deep. Therefore, a third drive unit is also provided to adjust the distance between the positioning plate and the machine head. Therefore, when the second drive unit drives the drilling unit downward, it also drives the connecting block downward. When the connecting block abuts the positioning plate, the connecting block and the drilling unit cannot move further downward, thereby limiting the downward movement of the drilling unit. The third drive unit can adopt a drive cylinder with controllable output shaft stroke, such as a pneumatic cylinder, an oil cylinder, or an electric cylinder. The use of a structure with adjustable positioning plate position can adjust the downward movement distance of the drill bit according to different products, which is suitable for processing different batches of products (all products in the same batch require the same processing hole position and no changes).

[0037] See also Figure 2 As shown, the drilling portion 2 includes a rotating member 13 and a connecting member 14. The rotating member 13 is rotatably installed in the machine head 1. The middle portion of the connecting member 14 is vertically slidably connected to the middle portion of the rotating member 13. The bottom of the connecting member 14 is arranged below the bottom surface of the machine head 1, and the top of the connecting member 14 is arranged above the top surface of the machine head 1.

[0038] A drill bit 15 is detachably mounted on the bottom of the connecting member 14. The top of the connecting member 14 is rotatably connected to the driving end of the second driving unit 4. The second driving unit 4 drives the connecting member 14 to move up and down along the rotating member. The top of the connecting member is connected to the driving end of the second driving unit via a connecting block.

[0039] The first driving part 3 drives the rotating member 13 to rotate in the machine head 1. A through hole is provided in the middle of the rotating member 13. The middle of the connecting member 14 is vertically slidably provided in the through hole.

[0040] A limiting member is further provided between the rotating member and the connecting member, and the limiting member limits the circumferential rotation of the connecting member relative to the rotating member.

[0041] In this embodiment, the limiting member includes a spline and a spline groove. The spline groove is provided on the inner wall of the rotary hole, and the spline is fixedly mounted on the outer surface of the connecting member. The spline is vertically slidably arranged in the spline groove. The spline and the spline groove limit the rotation of the connecting member relative to the rotating member. The rotating member is directly rotatably mounted in the machine head. A belt groove 16 is provided on the outer surface of the rotating member. One end of the belt is connected to the output shaft of the motor, and the other end is wound in the belt groove. The rotation of the belt is driven by the motor, thereby driving the rotation of the rotating member. Due to the presence of the limiting member, when the rotating member rotates, it will synchronously drive the connecting member and the drill bit at the bottom of the connecting member to rotate. When it is necessary to drive the drill bit up and down, the second drive unit drives the connecting member up and down. Since the spline is always inserted in the spline groove, when the connecting member moves up and down, the rotating member always drives the connecting member to rotate, thereby achieving up and down movement during the rotation of the drill bit.

[0042] Wherein, the second driving part is a driving cylinder, and the output shaft of the driving cylinder is rotatably connected to the top of the connecting member.

[0043] As another example, see Figure 2 As shown, a rack 17 is further provided on the drilling portion 2 , and the rack 17 is extended along the length direction of the drilling portion 2 ; the rack is provided on the connecting member.

[0044] A rotating rod 18 is also rotatably mounted on the machine head 1, and a gear 19 meshing with the rack 17 is provided at one end of the rotating rod 18, and a plurality of protrusions 20 are provided at the other end of the rotating rod 18. The plurality of protrusions 20 are arranged at intervals along the length direction of the rotating rod 18, and adjacent protrusions 20 are staggered.

[0045] The machine head 1 is provided with a plurality of sensors 21, the sensors 21 being electrically connected to the second driving unit 4, and each of the sensors 21 being respectively provided facing the outer surface of the rotating rod 18 where one of the protrusions 20 is located;

[0046] When the rotating rod 18 rotates, each protrusion 20 can face the corresponding sensor 21 .

[0047] When the connecting piece moves up and down, the rotating rod can be driven to rotate through the rack and gear. Figure 1 Taking the direction as an example, the gear is installed on the left side of the rotating rod, and the right end of the rotating rod is set on the right side of the head; and a plurality of sensors are provided above the rotating rod outside the head. The plurality of protrusions are arranged from left to right on the outer surface of the rotating rod, and there is a circumferential spacing between adjacent protrusions (that is, the protrusions are not on the outer surface of the same side of the rotating rod). The plurality of sensors are arranged at intervals from left to right, and each sensor is directly above the rotating rod where each protrusion is located. When the connecting member moves up and down, it will simultaneously drive the rotating rod to rotate and drive all the protrusions to rotate. When the corresponding protrusion rotates to face the corresponding sensor, the sensor detects the protrusion, so that the position of the bottom of the connecting member (the position of the bottom of the drill bit) can be known, and the data can be fed back to the second drive unit. A controller will be set up to be electrically connected to the first drive unit, the second drive unit, the third drive unit and the sensor, and a control program can also be pre-made therein. The sensor detects the position of the drill bit, and the controller can control the second drive unit (or according to the pre-made program in the second drive unit) to drive the connecting part to move down a distance, move up, move down or whether to stay, etc. according to the set degree.

[0048] The present invention also provides a drilling device, comprising the above-mentioned drilling component, wherein the bottom of the head is mounted on a base 23 via a column 22;

[0049] A product positioning platform (not shown in the figure) is further provided between the machine head and the base, and the product positioning platform is arranged directly below the drilling portion.

[0050] The base can be placed on a workbench or on the ground to support the drilling equipment, and the column is used to connect the machine head and the base. The product positioning table is used to place and limit the product, and is opposite to the drill bit, so that the product can be drilled when the drill bit moves up and down. In the present invention, the operator can manually place the product on the product positioning table, or the robot can directly grab the product and place it on the product positioning table, and then use the drilling component to automatically drive the drill bit to rotate and move up and down to quickly automatically or semi-automatically process the product, without the need for the operator to manually drive the drill bit up and down, thereby effectively reducing the labor intensity of the operator. At the same time, if an automated robot is used to take and put materials, there is no need for the operator to stand next to the drilling component (during drilling, the drill bit may break and collapse to the side of the drilling position, causing a safety hazard to the operator standing next to it), which can effectively reduce the safety hazards caused by drill bit breakage and the like.
