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.

[0040] like Figure 1-4 As shown, a power supply construction hole opening mechanism includes a base 1, a fixed frame 2, a drilling rig 5 and a workbench 10, wherein the fixed frame 2 is arranged above the base 1, and the fixed frame 2 is slidably connected to the base 1 through an adjusting mechanism 8, two electric push rods I3 are installed on the fixed frame 2, and the output ends of the two electric push rods I3 are commonly connected to a lifting plate 4, a drilling rig 5 is installed on the top surface of the lifting plate 4, the output end of the drilling rig 5 passes through the lifting plate 4 and is located below the lifting plate 4, the output end of the drilling rig 5 is connected to a drill bit 6, a pushing mechanism 7 is arranged below the drill bit 6, the pushing mechanism 7 is slidably installed on the base 1, the workbench 10 is installed on the pushing mechanism 7 through a connecting mechanism 9, and the pushing mechanism 7 is cooperatively connected with the adjusting mechanism 8.

[0041] When the power supply construction hole-drilling mechanism is used, the plate is first fixed on the workbench 10, and then the drilling machine 5 is started to drive the drill bit 6 to rotate, and then the electric push rod 13 on the fixed frame 2 is started, so that the electric push rod 13 extends and drives the drill bit 6 to move downward until the high-speed rotating drill bit 6 comes into contact with the plate on the workbench 10, and then a hole is drilled at the contact position of the plate, and the workbench 10 is completely moved away from under the drill bit 6 by the pushing mechanism 7, and then the loading work can be carried out without waiting for the drill bit 6 to move up, and there is no need to extend the arm under the drill bit 6 to work, thereby reducing the safety risk; the pushing mechanism 7 drives the workbench 10 to move horizontally left and right, and then the hole-drilling position is moved horizontally, and the adjustment mechanism 8 and the pushing mechanism 7 cooperate to enable the adjustment mechanism 8 to drive the drill bit 6 to move longitudinally forward and backward, and then the hole-drilling position is moved longitudinally, thereby ensuring the hole-drilling quality and improving work efficiency, and the workbench 10 is installed on the pushing mechanism 7 by the connecting mechanism 9, which is convenient for the operator to remove the workbench 10 for cleaning.

[0042] like Figure 1-12 As shown, a groove 11 is provided in the middle of the top surface of the base 1; the pushing mechanism 7 includes a servo motor 701, the servo motor 701 is installed on the back of the groove 11, and the output end of the servo motor 701 is connected to an electric push rod II702, and the output end of the electric push rod II702 is connected to a transmission gear column 703, and a first gear 704 is provided on one side of the transmission gear column 703, the first gear 704 is meshed with the transmission gear column 703, and the front and rear ends of the gear shaft of the first gear 704 are respectively rotatably connected to the support Seat 705, support seat 705 is installed on the bottom surface of groove 11, a tooth plate 706 is provided near the top of groove 11, tooth plate 706 is located above the first gear 704, and tooth plate 706 is meshed with the first gear 704, base 707 is slidably installed in groove 11, bottom surface of base 707 is connected with top surface of tooth plate 706, workbench 10 is installed on base 707 through connecting mechanism 9; protective plates 708 are installed on both sides of base 707, and two protective plates 708 are located on the top surface of base 1.

[0043] During specific implementation, in the process of drilling holes in the plate, in order to facilitate the staff to load and unload materials, the servo motor 701 is first started to drive the electric push rod II702 to rotate, and the electric push rod II702 drives the transmission gear column 703 to rotate. At this time, the transmission gear column 703 and the first gear 704 are meshed and connected. The rotation of the transmission gear column 703 causes the first gear 704 to rotate, and because the first gear 704 and the toothed plate 706 are meshed and connected, the first gear 704 rotates to cause the toothed plate 706 to move left and right. The movement of the toothed plate 706 causes the base 707 to slide along the groove 11 until the workbench 10 is completely removed from under the drill bit 6. At this time, the plate is placed on the workbench 10 or the plate on the workbench 10 is removed for loading or unloading, and the loading or unloading work can be carried out without waiting for the drill bit 6 to move up to the specified height, and there is no need to extend the arm under the drill bit 6 to work, thereby reducing the safety risk, thereby facilitating loading and unloading and reducing the safety risk when the power supply construction drilling mechanism is used.

[0044] Because protective plates 708 are installed on both sides of the base 707, the movement of the base 707 drives the two protective plates 708 to move together. When the base 707 slides along the groove 11, the two protective plates 708 can cover the groove 11, thereby preventing waste chips from entering the base 1 through the groove 11 when opening the hole.

[0045] like Figure 1-12 As shown, the back of the base 1 is provided with two guide holes 12, and the guide holes 12 are communicated with the inside of the groove 11; the adjusting mechanism 8 includes two threaded rods 801 arranged in the groove 11, and the front and rear ends of the threaded rod 801 are connected to the inner wall of the groove 11 through bearings, and a screw sleeve 802 is sleeved on the threaded rod 801, and a plurality of evenly distributed moving columns 807 are installed at the end of the screw sleeve 802 away from the synchronous wheel 803, and the rear end of the moving column 807 passes through the corresponding guide hole 12 and is located outside the base 1, and the moving column 807 can move forward and backward along the corresponding guide hole 12, and a synchronous wheel 803 is installed near the front end of the threaded rod 801, and the two synchronous wheels 803 are connected together by a synchronous belt 804, close to the transmission gear. A second gear 805 is installed on the threaded rod 801 of the column 703, and the second gear 805 can mesh with the transmission gear column 703. The rear ends of the multiple movable columns 807 are commonly connected to a guide plate 806, and the top end of the guide plate 806 is connected to the fixed frame 2; through holes 13 are respectively opened on both sides of the back side of the base 1 near the top, and through grooves 14 are respectively opened on both sides of the back side of the base 1 near the bottom; support columns 15 corresponding to the through holes 13 and support plates 16 corresponding to the through grooves 14 are installed in front of the guide plate 806, the support columns 15 are inserted into the corresponding through holes 13 and can move forward and backward along the corresponding through holes 13, and the support plates 16 are inserted into the corresponding through grooves 14 and can move forward and backward along the corresponding through grooves 14.

[0046] During specific implementation, in the process of drilling holes in the plate, when it is necessary to drill holes at different positions of the plate, the electric push rod II702 is started to extend and drive the transmission gear column 703 to move until the transmission gear column 703 is disengaged from the first gear 704. At this time, the transmission gear column 703 is meshed and connected with the second gear 805. Then, when the servo motor 701 is started to drive the transmission gear column 703 to rotate, the first gear 704 will not rotate, only the second gear 805 will rotate, and the second gear 805 drives the corresponding threaded rod 801 to rotate, and then the threaded rod 801 drives the synchronous wheel 803 thereon to rotate, and the synchronous wheel 803 drives another synchronous wheel 803 to rotate through the synchronous belt 804, and the other synchronous wheel 803 drives the corresponding threaded rod 801 to rotate. At this time, the two threaded rods 801 rotate simultaneously. When rotating, since the screw sleeve 802 is threadedly matched with the corresponding threaded rod 801, and the screw sleeve 802 is restricted by the moving column 807 and cannot rotate, the screw sleeve 802 moves forward and backward along the corresponding threaded rod 801, and the movement of the screw sleeve 802 drives the corresponding moving column 807 to move forward and backward, and several moving columns 807 move simultaneously to drive the guide plate 806 to move forward and backward, and the movement of the guide plate 806 drives the fixed frame 2 to move forward and backward, and then drives the drill bit 6 to move forward and backward, and because the guide plate 806 is connected to the support column 15 and the support plate 16, at this time, the support column 15 slides forward and backward along the corresponding through hole 13, and the support plate 16 slides forward and backward along the corresponding through groove 14, thereby guiding the movement of the guide plate 806, so that the fixed frame 2 drives the drill bit 6 to move smoothly, and then the hole opening position moves in the longitudinal direction forward and backward;

[0047] At the same time, the electric push rod II702 can be started to contract and drive the transmission gear column 703 to move until the transmission gear column 703 is meshed with the first gear 704 and the second gear 805. Then, when the servo motor 701 is started to drive the transmission gear column 703 to rotate, the first gear 704 and the second gear 805 both rotate, thereby causing the workbench 10 to move laterally and the drill bit 6 to move longitudinally, and then the hole opening position is moved laterally and longitudinally at the same time, so that there is no need to move the fixed plate, and holes can be opened at different positions of the plate according to production needs to ensure the quality of the holes. According to the needs of the staff, it is possible to choose to move the hole opening position laterally, move the hole opening position longitudinally, or move it laterally and longitudinally at the same time, thereby saving time and improving work efficiency. When the hole opening mechanism is used in power supply construction, it is convenient to adjust the hole opening position and improve work efficiency.

[0048] like Figure 8 , Fig. 9 , Fig.10As shown, the connecting mechanism 9 includes several slots 901 uniformly distributed laterally and two fixing seats 903, a card strip 902 is slidably provided in the slot 901, the top surface of the card strip 902 is connected to the bottom surface of the workbench 10, the fixing seat 903 corresponds to the protective plate 708, and the fixing seat 903 is installed on the top surface of the corresponding protective plate 708, two circular holes 904 are provided on the outer side of the fixing seat 903, a fixing rod 905 is provided in the circular hole 904, the fixing rod 905 can move along the corresponding circular hole 904, a spring 906 is sleeved on the fixing rod 905, one end of the spring 906 is connected to the inner wall of the circular hole 904, and the other end is connected to the fixing rod 905; two guide holes 17 are respectively provided on both sides of the workbench 10, a guide rod 18 is provided in the guide hole 17, the guide rod 18 can move along the corresponding guide hole 17, and the outer end of the guide rod 18 and the fixing rod 905 located on the same side are connected together through an H-shaped plate 19.

[0049] During specific implementation, when it is necessary to remove the workbench 10 for cleaning during the process of drilling holes in the plate, the H-shaped plate 19 is first pulled outward, and the H-shaped plate 19 drives the guide rod 18 to move outward along the corresponding guide hole 2 17 and the fixed rod 905 to move outward along the corresponding circular hole 904. When the guide rod 18 is completely separated from the corresponding guide hole 2 17 and the fixed rod 905 is completely separated from the corresponding circular hole 904, the workbench 10 is no longer fixed. At the same time, the workbench 10 is pulled outward, and the workbench 10 moves and drives the card strip 902 to move together until the card strip 902 is connected to the card slot 901. Then the workbench 10 can be removed for cleaning and maintenance, and the disassembly and assembly are convenient and the operation is simple.

[0050] When the workbench 10 needs to be installed back on the base 707, first pull the H-shaped plate 19 outward to make the guide rod 18 completely disengage from the corresponding guide hole 17 and the fixing rod 905 completely disengage from the corresponding circular hole 904. At the same time, move the workbench 10 so that the card strip 902 is inserted into the card slot 901, thereby limiting the position of the workbench 10. Then release the H-shaped plate 19. At the same time, since the spring 906 is in a stretched state, under the action of the elastic force of the spring 906, the fixing rod 905 enters the corresponding circular hole 904 and the guide rod 18 enters the corresponding guide hole 17, thereby fixing the workbench 10 to prevent movement.

[0051] like Fig.13 As shown, the groove 11 has a slide groove 20 at both the front and rear sides, and a bar block 21 is slidably arranged in the slide groove 20, and the bar block 21 is connected to the base 707. Through the above structure, the base 707 can be slidably installed on the base 1 and ensure that the base 707 can move stably, thereby ensuring that the plate to be processed on the workbench 10 moves steadily.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
