Description

Technical Field

[0001] The present application relates to the technical field of turning processing, and in particular to a turning processing device for accessories of large-scale bridge erection equipment. Background Art

[0002] Large bridge equipment is a special mechanical equipment used for bridge construction and maintenance, mainly used in bridge erection, dismantling and maintenance processes. These equipment usually have high load-bearing capacity and stability to ensure safety and reliability during construction. In order to be able to manufacture various parts suitable for bridge equipment, it usually involves drilling and cutting metal materials, and turning is a common metal processing process.

[0003] For example, in the existing Chinese patent with the publication number CN211248393U, a clamping and drilling device for hardware accessories is disclosed, which includes a base, two mutually symmetrical support plates are fixedly connected to the upper side wall of the base, a top plate is fixedly connected to the upper side walls of the two support plates, a placement plate is fixedly connected to the opposite side walls of the two support plates, a through hole is penetrated through the side wall of the placement plate, a clamping mechanism is provided on the placement plate, an electric push rod is fixedly connected to the upper side wall of the top plate, the end of the output shaft of the electric push rod penetrates the side wall of the top plate and is fixedly connected to a device block, a drilling mechanism is provided on the device block, and a material collecting mechanism is provided on the base. Through the above-mentioned existing technology, the clamping mechanism is used to clamp and fix the hardware accessories first, and then the clamped hardware accessories are punched by the drilling mechanism, and some debris can be collected by the material collecting mechanism.

[0004] However, the above prior art has the following technical defects: When the above-mentioned prior art is used, the hardware accessories are first placed on the placement plate, and the knobs on the two threaded rods are respectively turned to drive the clamping block to rotate and move downward together. The hardware accessories are clamped by the cork gasket, and the electric push rod drives the device block together with the motor and the drill bit to move downward, and the hardware accessories are driven by the motor to perform drilling operations. When the above-mentioned device drills holes in the clamped and fixed hardware accessories, it can only drill holes at the position directly below the drill bit, and the drill bit position cannot be adjusted; if it is necessary to drill holes in other positions of the hardware accessories, it is necessary to first release the clamping and fixation of the hardware accessories, readjust the placement position of the hardware accessories, and then clamp and fix them again, and move the drill bit down to complete the drilling. As a result, when drilling holes in multiple positions of hardware accessories, the operation is cumbersome and the efficiency of multi-position drilling processing is low.

[0005] Secondly, the above-mentioned device cannot drill holes in accessories at precise positions, and the drilling positions are relatively random. When a hole needs to be drilled at a specified position of an accessory, the placement of the accessory can only be adjusted so that the position where the hole needs to be drilled is as directly below the drill bit as possible. However, the actual position after drilling will inevitably deviate from the specified drilling position.

[0006] Based on this, on the basis of the existing clamping and drilling device for hardware accessories, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

[0037] The following is combined with Figure 1-Figure 15 This application is described in further detail.

[0038] The embodiment of the present application discloses a device for turning accessories of large-scale bridge-building equipment, which can quickly clamp and fix accessories of different sizes, and can automatically locate the center position of the accessory during the clamping process to facilitate limiting the drilling position of the accessory, and can also perform multi-position drilling operations on the accessory. Embodiment 1

[0039] Reference Figure 1 and Figure 2As shown, the present application provides a turning processing device for accessories of large-scale bridge-building equipment, including an equipment table 1 and a processing back plate 11 installed on the upper side of the equipment table 1. A plurality of L-shaped support plates 12 and L-shaped side plates 13 are sequentially arranged on one side of the processing back plate 11. It should be noted that the plurality of L-shaped support plates 12 are equidistantly arranged on the processing back plate 11 in the horizontal direction, and the plurality of L-shaped side plates 13 are equidistantly arranged on the processing back plate 11 in the vertical direction, and the adjacent L-shaped support plates 12 and L-shaped side plates 13 are arranged at right angles. An equipment accessory 14 to be processed is placed on the L-shaped support plate 12, and a positioning processing device 2 is provided on the processing back plate 11, which is used to clamp and fix the placed equipment accessory 14, and can automatically locate the center position of the clamped equipment accessory 14, so that the operator can accurately punch a hole in the center of the equipment accessory 14.

[0040] Since the L-shaped support plate 12 and the L-shaped side plate 13 are both L-shaped, when the equipment accessory 14 is placed on the L-shaped support plate 12 and the L-shaped side plate 13 and clamped and fixed, the back side of the equipment accessory 14 will not contact the processing back plate 11, so as to facilitate the processing of the through-hole of the equipment accessory 14.

[0041] It should be noted that the shape of the equipment accessories 14 to be processed that can be placed on the processing back plate 11 is not limited to the L-shape shown in the figure, but can also be a rectangle of different lengths and widths. Two rectangular equipment accessories 14 to be processed of different sizes can be placed on the upper side of multiple L-shaped support plates 12 and against one side of multiple L-shaped side plates 13. The two rectangular equipment accessories 14 to be processed can be clamped and fixed by the positioning processing device 2 separately. This further improves practicality and meets the requirements for equipment accessories 14 of different shapes that need to be punched.

[0042] Reference Figure 3 and Figure 4 As shown, specifically, the positioning processing device 2 includes a T-shaped pressure rod 21 which is limitedly slidably arranged on the processing back plate 11 and is located above the equipment accessory 14. The processing back plate 11 is provided with a limit slide 111 for installing the T-shaped pressure rod 21. A driving cylinder 22 whose telescopic end is connected to the lower side of the T-shaped pressure rod 21 is installed in the processing back plate 11. The contraction of the driving cylinder 22 can drive the T-shaped pressure rod 21 to slide vertically downward. The processing back plate 11 is provided with an assembly inner hole 112 which is connected with the limit slide 111 for installing the driving cylinder 22. The T-shaped pressure rod 21 is provided with a lower pressing plate 24 which slides up and down through two limit rods 23. The T-shaped pressure rod 21 is provided with a round rod hole 211 for installing the two limit rods 23. The two limit rods 23 are fixedly connected with the lower pressing plate 24. Under the restriction of the two limit rods 23, the lower pressing plate 24 is subjected to force and can slide in a limited position below the T-shaped pressure rod 21. The T-shaped pressure rod 21 and the processing back plate 11 are provided with a limiting unit 3 for being driven by the driving cylinder 22 to firmly clamp the placed equipment accessory 14 to be processed.

[0043] Reference Figure 5 As shown, in order to clamp and fix the equipment accessories 14 to be processed placed on the L-shaped support plate 12 and the L-shaped side plate 13, the limiting unit 3 includes a limiting end rod 31, a push-down spring 32 and a clamping mechanism 4; the limiting end rod 31 is installed on the upper ends of the two limiting rods 23 to prevent the lower pressing plate 24 from moving downward and separating from the T-shaped pressure rod 21; the two push-down springs 32 are respectively sleeved on the two limiting rods 23 between the T-shaped pressure rod 21 and the lower pressing plate 24, and the two push-down springs 32 always have a driving force to push the lower pressing plate 24 downward. The clamping mechanism 4 is arranged on the processing back plate 11 located on one side of the equipment accessories 14, and is used to cooperate with the L-shaped side plate 13 to clamp and fix the equipment accessories 14 to be processed located on one side of the L-shaped side plate 13.

[0044] Reference Figure 6 and Figure 7 As shown, in order to further improve the punching efficiency, two rectangular equipment accessories 14 to be processed with different lengths and widths are placed on the L-shaped support plate 12 and one side of the L-shaped side plate 13 horizontally and vertically respectively. When the driving cylinder 22 is started for clamping and fixing, the two equipment accessories 14 can be clamped separately and firmly. The clamping mechanism 4 includes a triangular back plate 41, a side pressure plate 42 and a linkage assembly 5; it should be noted that the lower pressure plate 24 and the side pressure plate 42 are both L-shaped, which can cooperate with the L-shaped support plate 12 and the L-shaped side plate 13 to firmly clamp the equipment accessories 14, while preventing the back side of the equipment accessories 14 from contacting the processing back plate 11. The triangular back plate 41 is installed on the processing back plate 11 located on one side of the equipment accessory 14 by limiting sliding through a dovetail block 43. A dovetail groove 113 is provided on the processing back plate 11 for installing the dovetail block 43. Two spring rods 44 are symmetrically embedded and installed on the triangular back plate 41. The triangular back plate 41 is symmetrically provided with rectangular grooves 411 for installing the two spring rods 44. The two spring rods 44 are fixedly connected to the triangular back plate 41, and can perform lateral limited sliding when the triangular back plate 41 is subjected to force.

[0045] The side pressure plate 42 is inserted and slidably arranged on the side of the triangular back plate 41 facing the equipment accessories 14 through the polygonal rod 45, and the side pressure plate 42 is connected to the telescopic ends of the two spring rods 44. The triangular back plate 41 is penetrated with a limiting hole 412 for the installation of the polygonal rod 45. The two spring rods 44 always have a driving force to push the side pressure plate 42 toward the L-shaped side plate 13. The polygonal rod 45 ensures that the side pressure plate 42 can slide stably when it is stressed to avoid angular deviation. The linkage component 5 is arranged on the T-shaped pressure rod 21 and the triangular back plate 41, and is used to cooperate with the T-shaped pressure rod 21 to limit the triangular back plate 41.

[0046] Replay Figure 6As shown, since the triangular back plate 41 needs to be driven to slide horizontally by the movement of the T-shaped pressure rod 21, the linkage assembly 5 includes a linkage drive plate 51 and a linkage drive shaft 52; the linkage drive plate 51 is installed on one side of the T-shaped pressure rod 21, and the linkage drive plate 51 and the T-shaped pressure rod 21 are fixedly connected; the linkage drive shaft 52 passes through the linkage drive plate 51 and is rotatably arranged on the triangular back plate 41, and an inclined through groove 511 is opened on the linkage drive plate 51 for the installation of the linkage drive shaft 52.

[0047] When the driving cylinder 22 is started and contracted to drive the T-shaped pressure rod 21 to move downward, the downward pressure plate 24 can be driven to move downward and press against the upper side of the equipment accessory 14. At the same time, the downward movement of the T-shaped pressure rod 21 can synchronously drive the linkage drive plate 51 to move downward. Under the action of the inclined through groove 511 opened on the linkage drive plate 51, the triangular back plate 41 can be driven to move laterally toward the L-shaped side plate 13 through the linkage drive shaft 52, and the side pressure plate 42 can be driven to move toward the direction of the equipment accessory 14. Under the action of the two spring rods 44, the side pressure plate 42 can be pressed against one side of the equipment accessory 14.

[0048] Under the action of the push-down spring 32, the lower pressing plate 24 has a certain distance from the T-shaped pressing rod 21, while the side pressing plate 42 has a certain distance from the triangular back plate 41 under the action of the spring rod 44, so that when one of the lower pressing plate 24 or the side pressing plate 42 first contacts the equipment accessory 14, the other can continue to move until it is tightly pressed against the equipment accessory 14, and then the driving cylinder 22 is stopped, so that the L-shaped equipment accessory 14 to be processed can be clamped and fixed from multiple directions. When two rectangular equipment accessories 14 to be processed of different sizes are placed horizontally and vertically, the two rectangular equipment accessories 14 can also be clamped and fixed separately.

[0049] Reference Figure 8 As shown, in order to automatically locate the center position of the equipment accessory 14 to be processed and to accurately punch the center position of the equipment accessory 14, a positioning mechanism 6 is also provided on one side of the lower pressure plate 24 and the side pressure plate 42. The positioning mechanism 6 includes a main moving rod 60 arranged at one end of the lower pressure plate 24, and a main supporting rod 61 is installed at one end of the L-shaped support plate 12 away from the L-shaped side plate 13. It should be noted that the main supporting rod 61 is installed on the outermost L-shaped support plate 12 and is fixedly connected to the L-shaped support plate 12. A main rhombus connecting rod 62 is provided between the main moving rod 60 and the main supporting rod 61. It should be noted that the main rhombus connecting rod 62 is arranged by four connecting rods hinged to each other, and can be symmetrically deformed when subjected to force.

[0050] The lower side of the main moving rod 60 and the surface of the lower pressing plate 24 that contacts the equipment accessory 14 when the main moving rod 60 moves downward are in the same plane, while the upper side of the main supporting rod 61 and the surface of the L-shaped supporting plate 12 that supports the equipment accessory 14 are in the same plane. When the driving cylinder 22 starts to contract to clamp and fix the equipment accessory 14, the main moving rod 60 will move downward synchronously with the lower pressing plate 24, and the distance between the main moving rod 60 and the main supporting rod 61 will be reduced, which will drive the main diamond-shaped connecting rod 62 to deform and expand.

[0051] Reference Fig. 9 As shown, the two symmetrically hinged ends of the main rhombus connecting rod 62 are provided with a main reference rod 64 through two main limiting circular blocks 63, and the main reference rod 64 has a limiting notch 641 adapted to the two main limiting circular blocks 63. When the equipment accessory 14 is clamped and fixed, the distance between the main moving rod 60 and the main supporting rod 61 is reduced, and the main rhombus connecting rod 62 is deformed and expanded. Since the main rhombus connecting rod 62 is symmetrically hinged, the distance between the two main limiting circular blocks 63 is expanded, and the height will be lowered, but because the ends of the connecting rods of the main rhombus connecting rod 62 are symmetrically hinged, the two main limiting circular blocks 63 are always in a parallel state, and the main reference rod 64 is always in the middle position between the main moving rod 60 and the main supporting rod 61.

[0052] Therefore, when the distance between the main moving rod 60 and the main supporting rod 61 changes, the main reference rod 64 will automatically adjust its position to always be located in the middle between the main moving rod 60 and the main supporting rod 61. When the lower pressing plate 24 moves down and presses against the equipment accessory 14, the distance between the lower pressing plate 24 and the L-shaped supporting plate 12 is the height of the equipment accessory 14, that is, the position of the main reference rod 64 is the center line position of the equipment accessory 14. This achieves the effect of automatically positioning the center position of the equipment accessory 14 when clamping and fixing equipment accessories 14 of different sizes.

[0053] Reference Fig.10 and Fig.11 As shown, considering that two rectangular equipment accessories 14 to be processed of different sizes are clamped on the L-shaped support plate 12 and the L-shaped side plate 13 at the same time, it is also necessary to automatically locate the center position of the equipment accessories 14 clamped between the L-shaped side plate 13 and the side pressure plate 42, a secondary moving rod 65 is provided at the lower end of the side pressure plate 42, and a secondary supporting rod 66 is installed at the bottom end of the L-shaped side plate 13, and a secondary diamond-shaped connecting rod 67 is provided between the secondary moving rod 65 and the secondary supporting rod 66. Like the above-mentioned main diamond-shaped connecting rod 62, it is provided with four connecting rods symmetrically hinged to each other. When the side pressure plate 42 is forced to slide toward the direction of the equipment accessory 14 to clamp and fix it, the secondary moving rod 65 moves with the side pressure plate 42, and the distance between the secondary moving rod 65 and the secondary supporting rod 66 becomes smaller, driving the secondary diamond-shaped connecting rod 67 to deform and expand.

[0054] The two symmetrical hinged ends of the secondary rhombus connecting rod 67 are provided with secondary reference rods 69 through two secondary limiting round blocks 68, and the secondary reference rods 69 have two limiting notches 691 adapted to the two secondary limiting round blocks 68. The principle of automatically adjusting the position of the main reference rod 64 after the main rhombus connecting rod 62 is deformed by force is the same as that of the above-mentioned main rhombus connecting rod 62, so it will not be repeated.

[0055] The effect achieved is that when the side pressure plate 42 and the L-shaped side plate 13 clamp and fix a rectangular equipment accessory 14 of another size to be processed, the distance between the secondary moving rod 65 and the secondary supporting rod 66 is reduced through the tight clamping of the side pressure plate 42, and the secondary diamond-shaped connecting rod 67 is symmetrically deformed to adjust the position of the secondary reference rod 69, so that the secondary reference rod 69 is located at the center line position of the vertically placed equipment accessory 14. In this way, the effect of automatically positioning the center position of the equipment accessories 14 in the corresponding clamping area can be achieved while clamping and fixing two rectangular equipment accessories 14 of different sizes to be processed respectively according to the different clamping distances between the lower pressure plate 24 and the L-shaped supporting plate 12, and the side pressure plate 42 and the L-shaped side plate 13.

[0056] Reference Fig.12 and Fig.13 As shown, since it is necessary to perform drilling operations on the equipment accessories 14 after clamping and fixing, and to meet the requirements of drilling holes in multiple positions, a drilling assembly 7 is also provided on the processing back plate 11. The drilling assembly 7 includes a square bottom column 71 that is slidingly arranged on the processing back plate 11 through a limit position. An L-shaped slot 114 is opened through the processing back plate 11 for the square bottom column 71 to slide. Two U-shaped clamping plates 72 are clamped on the square bottom column 71, and the two U-shaped clamping plates 72 are located on both sides of the processing back plate 11; the two U-shaped clamping plates 72 are fixedly connected to the square bottom column 71, which has the effect of limiting the position of the square bottom column 71, so that the square bottom column 71 can be subjected to force and can slide in the L-shaped slot 114 smoothly without angular deviation.

[0057] A rectangular base 73 is slidably mounted on the square bottom column 71, and a rectangular slot 711 is provided on the square bottom column 71 for mounting the rectangular base 73. It should be noted that the rectangular base 73 is composed of two symmetrical parts, so that the limited position clamping device can be slidably mounted on the rectangular slot 711 of the square bottom column 71. After the installation is completed, the two parts of the rectangular base 73 can be fixed by welding or other methods, so that the rectangular base 73 can be stably slid on the square bottom column 71 under the force, and will not be separated from the square bottom column 71. A U-shaped push handle 74 is installed on the lower side of the rectangular base 73. The U-shaped push handle 74 is pushed to drive the rectangular base 73 to slide on the square bottom column 71.

[0058] Reference Fig.13 and Fig.14As shown, a U-shaped side bar 75 and a polygonal side bar 76 are vertically mounted on the rectangular base 73, and the U-shaped side bar 75 and the polygonal side bar 76 are fixedly mounted on the rectangular base 73. A limit seat 77 is provided between the U-shaped side bar 75 and the polygonal side bar 76 for limited sliding, and the limit seat 77 has a limit slot 771 and a limit through hole 772 adapted to the U-shaped side bar 75 and the polygonal side bar 76, and a drilling device 79 is installed on the limit seat 77 through a supporting rod seat 78. The drilling device 79 consists of a motor and a drill bit, and drill bits of different apertures can be replaced according to actual drilling requirements.

[0059] After the equipment accessory 14 to be processed is clamped and fixed, the operator can quickly and accurately adjust the height of the drilling equipment 79 through the position of the main reference rod 64 at this time, so that the drill bit and the main reference rod 64 are at the same height, and then the square base column 71 is pushed horizontally to slide in the direction of the equipment accessory 14. When it moves to the drilling position, the U-shaped push handle 74 is pressed in the direction of the equipment accessory 14, and the drilling equipment 79 is driven to move in the direction of the equipment accessory 14 by driving the displacement of the rectangular base 73, so as to achieve the effect of drilling a hole in the middle position of the equipment accessory 14.

[0060] When it is necessary to punch holes in the equipment accessory 14 between the side pressure plate 42 and the L-shaped side plate 13, when the square bottom column 71 moves to the right angle position of the L-shaped slot 114, it is rotated 90 degrees toward the side pressure plate 42. The U-shaped side rod 75 and the polygonal side rod 76 are converted from the vertical state to the horizontal state, and the square bottom column 71 is driven to move down to the bottom of the L-shaped slot 114. At this time, the position of the drilling device 79 is adjusted according to the position of the secondary reference rod 69, so that the drill bit and the secondary reference rod 69 are on the same central axis, and then the square bottom column 71 is pushed up to push the drilling device 79 to move up. After moving to the punching position, the U-shaped push handle 74 is pressed to make the drilling device 79 punch holes in the equipment accessory 14, so as to achieve the effect of punching holes in the middle position of the equipment accessory 14 clamped between the side pressure plate 42 and the L-shaped side plate 13. Embodiment 2

[0061] Reference Fig.15As shown, on the basis of the first embodiment, in order to facilitate the operator to adjust and lock the height of the drilling equipment 79 according to the positions of the main reference rod 64 and the auxiliary reference rod 69, so as to better perform drilling operations on the equipment accessories 14, a regulating component 8 is provided on the U-shaped side rod 75 and the limit seat 77, and the regulating component 8 includes an assembly end block 81 fixedly mounted on the upper end of the U-shaped side rod 75, and an adjusting threaded rod 82 with a thread passing through the limit seat 77 is rotatably installed on the assembly end block 81, and a circular through hole 811 is penetrated on the assembly end block 81 for rotatably installing the adjusting threaded rod 82, and an internal threaded hole 773 is threadedly opened on the limit seat 77 to match the adjusting threaded rod 82, and a positioning rod 84 is slidably inserted through a circular collar 83 on the outer side of the limit seat 77. It should be noted that the circular ring 83 is fixedly connected to the limit seat 77, the central axis of the positioning rod 84 is on the same horizontal plane as the central axis of the drill bit on the drilling equipment 79, and the outer diameter of the positioning rod 84 is adapted to the opening width of the main reference rod 64 and the auxiliary reference rod 69, so the positioning rod 84 can be inserted into the main reference rod 64 and the auxiliary reference rod 69.

[0062] By rotating the adjusting threaded rod 82 and cooperating with the internal threaded hole 773 provided on the limiting seat 77, the position of the limiting seat 77 can be adjusted and locked, that is, the position of the drilling device 79 can be adjusted. After the equipment accessory 14 is clamped and fixed, the height of the drilling device 79 can be adjusted by rotating the adjusting threaded rod 82 according to the position of the main reference rod 64, until the positioning rod 84 is pressed and the positioning rod 84 can be inserted into the main reference rod 64, and the central axis of the drill bit on the drilling device 79 coincides with the central axis of the main reference rod 64, that is, at this time, the height of the drill bit is located in the middle of the equipment accessory 14. Push the square base column 71 to slide laterally. When the positioning rod 84 slides out of the main reference rod 64, pull the positioning rod 84 to reset it to avoid the positioning rod 84 from colliding with the equipment accessory 14 during the subsequent movement of the square base column 71. After driving the square base column 71 to move to the punching position, pressing the U-shaped push handle 74 can make the drill bit on the drilling equipment 79 contact with the middle of the equipment accessory 14, ensuring that the hole to be punched is in the middle of the equipment accessory 14, so as to achieve the effect of accurately punching a hole in the middle of the equipment accessory 14.

[0063] When drilling holes in the equipment accessory 14 between the opposite side pressure plate 42 and the L-shaped side plate 13, the operating principle is the same. The adjusting threaded rod 82 is rotated to adjust the position of the drilling device 79 until the positioning rod 84 is pressed and the positioning rod 84 can be inserted into the secondary reference rod 69. Then the square bottom column 71 is pushed upward. When the positioning rod 84 slides out of the secondary reference rod 69, the positioning rod 84 is pulled to reset. By continuously adjusting and pushing the square bottom column 71 to different positions and pressing the U-shaped push handle 74, it is possible to perform drilling operations in different areas and multiple positions on the equipment accessory 14, and the drilling positions are all in the middle of the equipment accessory 14. The purpose of accurately drilling holes in multiple positions of the equipment accessory 14 is achieved.

[0064] The implementation principle of this embodiment is: (1) Accessory placement: According to actual processing requirements, an L-shaped equipment accessory 14 or two rectangular equipment accessories 14 of different sizes can be placed on the processing back plate 11. The two rectangular equipment accessories 14 can be placed horizontally on the upper side of multiple L-shaped support plates 12, and vertically against one side of multiple L-shaped side plates 13.

[0065] (2) Clamping and fixing: Then the driving cylinder 22 is started to contract and drive the lower pressure plate 24 to move downward and press against the upper side of the equipment accessory 14. Under the action of the linkage driving plate 51, the triangular back plate 41 can also be driven to move laterally toward the L-shaped side plate 13, so that the side pressure plate 42 moves toward the equipment accessory 14 and presses against one side of the equipment accessory 14. The equipment accessory 14 to be processed can be firmly clamped from different directions.

[0066] (3) Automatic positioning: When the lower pressure plate 24 moves downward and presses against the equipment accessory 14, the main diamond-shaped connecting rod 62 is deformed to drive the height of the main reference rod 64 to be adjusted, and the center position of the equipment accessory 14 is positioned according to the height of the main reference rod 64. Through the tight clamping of the side pressure plate 42, the symmetrical deformation of the secondary diamond-shaped connecting rod 67 can adjust the position of the secondary reference rod 69, so as to achieve the effect of automatically positioning the center position of the equipment accessory 14 in the corresponding clamping area according to the different clamping distances between the lower pressure plate 24 and the L-shaped support plate 12, and the side pressure plate 42 and the L-shaped side plate 13.

[0067] (4) Precise drilling: After clamping and fixing the equipment accessory 14, turn the adjustment threaded rod 82 through the position of the main reference rod 64 until the positioning rod 84 can be inserted into the main reference rod 64 by pressing, and push the square bottom column 71 to slide horizontally. When the positioning rod 84 slides out of the main reference rod 64, pull the positioning rod 84 to reset. After the square bottom column 71 moves to the drilling position, press the U-shaped push handle 74 to drill a hole in the middle of the equipment accessory 14.

[0068] When the square bottom column 71 moves to the right angle position of the L-shaped slot 114, it is rotated 90 degrees in the direction of the side pressure plate 42. The square bottom column 71 is driven to move down to the bottom of the L-shaped slot 114. The adjusting threaded rod 82 is rotated until the positioning rod 84 can be inserted into the secondary reference rod 69, and then the square bottom column 71 is pushed upward, the positioning rod 84 is separated from the secondary reference rod 69, and then the positioning rod 84 is pulled to reset. By continuously adjusting and pushing the square bottom column 71 to move to different positions, and cooperating with pressing the U-shaped push handle 74, the drilling equipment 79 is used to perform multi-position drilling in different areas on the equipment accessory 14. The positions of the holes are all in the middle of the equipment accessory 14, thereby achieving the effect of multi-position precise drilling of the equipment accessory 14.

[0069] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
