Description

Technical Field

[0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a portable drilling and cutting auxiliary device and a use method thereof. Background Art

[0002] During the shipbuilding process, on-site construction personnel of various professions will often encounter the need to drill, tap and cut ship parts and mechanical parts.

[0003] However, the traditional onboard construction method has many inconveniences. For example, since ships are generally not equipped with drilling machines for drilling and cutting machines for cutting, the parts and equipment on board are processed and installed at a later stage, which slows down the construction progress. In addition, ship equipment is generally not allowed to be used during on-site construction. Therefore, the drilling and tapping of onboard parts often requires the parts to be transported to the workshop and used for drilling machines, and the cutting of large profiles requires manual transportation to the workshop and use of grinding wheel cutters. This not only increases the additional transportation workload of a large number of parts to be processed, but also brings construction safety hazards. At the same time, the back and forth transportation and disassembly and assembly wastes labor and prolongs the construction period.

[0004] In addition, when manual drilling and cutting tools such as portable hand-held drills or hand-held cutters are used for drilling or cutting on board, resistance will be generated after the drill head of the drilling and cutting tool contacts the object to be processed. Therefore, the control of processing positioning and processing depth depends largely on the personal experience of the construction personnel and the stability of the operation when holding the tool, which can easily cause human errors and affect the quality of drilling and cutting. Since the quality and positioning accuracy of hole opening and cutting in the shipbuilding process have a huge impact on the safety of the ship, the processed parts that do not meet the drilling and cutting quality after processing can only be discarded, which increases the waste of material costs. At the same time, hand-held operation also has certain safety risks, especially on ships where body balance cannot be ensured, which is more likely to cause personal accidents and personal injuries.

[0005] After searching, the Chinese utility model document with the existing announcement number CN202861456U discloses a portable electric drill positioning device, "composed of an electric drill, a feed mechanism, and a positioning seat, characterized in that: the electric drill is connected to the sliding body through a pressure plate and fastened with a bolt pair, the sliding body and the bracket body form a sliding fit, the rack provided on the sliding body is meshed with the gear shaft, the feed wheel is fixed to the shaft end of the gear shaft, an electromagnet is provided on the bottom surface of the bracket body, and a drill sleeve hole coaxial with the axis of the electric drill is provided on the base of the bracket body". Although the device can realize the fixing of the handheld electric drill and vertically drilling downward, avoiding the labor of long-term handheld operation, it is impossible to achieve accurate positioning of the workpiece to be processed, and the depth accuracy of processing cannot be guaranteed, which has certain limitations. Summary of the invention

If it does not meet the requirements, repeat step S5 for trimming; if it meets the requirements, complete the processing of the current workpiece to be processed, continue the operation of the next workpiece to be processed, and repeat steps S2-S5 until all workpieces to be processed have completed the processing operation.

[0020] As a preferred technical solution, the specific steps of step S1 include:

[0021] S1-1. Place the portable cutting and drilling auxiliary device on board the vessel so that the auxiliary device is in a horizontal or nearly horizontal position;

[0022] S1-2, locking and fixing the drilling and cutting tool to the lower bracket by means of a fixing clamp;

[0023] S1-3. Use the grip to press the upper support rod downward, and determine whether the installation and positioning of the drilling tool is accurate by observing whether the drilling head at the lower end of the drilling tool can pass through the drilling gap vertically during pre-compression; if there is a deviation, adjust the fixed angle of the drilling tool on the fixing clamp until the drilling head at the lower end of the drilling tool can pass through the drilling gap smoothly.

[0024] As a preferred technical solution, the specific steps of step S2 include:

[0025] S2-1. According to the processing depth of the workpiece to be processed, ensure that the size of the drill bit is not less than the processing depth;

[0026] S2-2, loosen the first locking eye ring, adjust the position of the fixing ring on the column bracket, so that the height of the lower end point of the drilling and cutting tool from the upper end surface of the base is higher than the height of the workpiece to be processed, ensuring the effective travel distance of the drilling and cutting tool;

[0027] S2-3. Tighten the locking eye ring on the fixing ring to lock the fixing ring on the column bracket.

[0028] As a preferred technical solution, the specific steps of step S3 include:

[0029] S3-1, first place the workpiece to be processed in the drilling and cutting gap on the base, press the grip downward until the drilling head contacts the upper surface of the workpiece to be processed, and then adjust the position of the workpiece to be processed according to the deviation between the machining center of the workpiece to be processed and the center of the drilling head;

[0030] S3-2. Use the pressure plate assembly to fix the workpiece to be processed: First, loosen the fasteners located on the upper and lower sides of the pressure plate body, adjust the height and rotation angle of the pressure plate body, until the contact area between the pressure plate body and the upper end surface of the workpiece to be processed is the largest and avoids the machining center line; then, adjust and tighten the fasteners on the pressure plate from bottom to top in sequence, so that the pressure plate body presses and fixes the workpiece to be processed.

[0034] S4-2. Adjust the position of the limit ring on the column bracket based on the relative zero line: move the limit ring below the relative zero line and fix it so that the distance from the scale on the upper end face of the limit ring to the relative zero line is the same as the processing depth.

[0035] As a preferred technical solution, the specific steps of processing the workpiece to be processed in step S5 include: slightly lifting the holding portion to leave a gap between the lower end of the drilling tool and the upper surface of the workpiece to be processed, starting the power supply of the drilling tool, pressing the holding portion downward to apply force, and as the drilling head of the drilling tool moves downward, the sliding ring also moves downward synchronously until it contacts and is limited by the limiting ring. At this time, the processing depth reaches the drilling requirement, the holding portion is released to unload the force, and the sliding ring moves upward and automatically rebounds and resets under the contraction and reset action of the reset spring, so that the drilling head at the lower end of the drilling tool is separated from the workpiece to be processed that has been processed.

[0036] As described above, the present invention has the following beneficial effects:

[0037] (1) The portable drilling and cutting auxiliary device and the method of use of the present invention can be directly transported to a construction vessel for use without relying on any other large-scale processing equipment. By operating the fixing clamps on the bracket, existing portable drilling and cutting tools such as handheld drilling machines and handheld cutting machines can be quickly installed and fixed. This design greatly simplifies the disassembly and assembly process, avoiding the need for on-site construction personnel to disassemble and assemble the workpieces to be processed and transport them to the indoor site for drilling or cutting, which is a waste of reciprocating lifting and transportation work, thereby saving a lot of labor and construction period and improving construction efficiency; at the same time, it also enables a single person to complete the drilling or cutting processing operations, significantly improving on-site construction efficiency.

[0038] (2) The portable drilling and cutting auxiliary device and the method of use of the present invention utilize the vertical up and down movement of the sliding ring mounted on the column bracket relative to the fixed ring as a guide, combined with the stable fixation of the workpiece by the pressure plate assembly, to ensure the accuracy of drilling and cutting. This accuracy not only improves the processing quality, but also helps to reduce material waste and improve the economic benefits of construction; and, by applying force to the operating bracket and utilizing the hinge linkage, the portable drilling and cutting operation can be completed, which improves the stability during the drilling and cutting process, avoids the errors caused by hand-held operation, and makes the processing more accurate and reliable; at the same time, the design of the operating bracket and the fixing clamp fully considers the swing of the drilling head at the lower end of the drilling and cutting tool during the drilling and cutting process, which helps to reduce the accidental risks caused by hand-held operation during the drilling and cutting operation, and further enhances the safety of the operation.

[0039] (3) The portable drilling and cutting auxiliary device and its use method of the present invention realize the functions of labor saving and rapid positioning through the drilling and cutting gap and spring reset mechanism on the base. Construction personnel can press down to the pre-pressing height to realize the simulation operation before formal drilling and cutting, and easily align the lower end center of the drilling and cutting tool with the drilling and cutting center of the workpiece to be processed, ensuring precise positioning before drilling and cutting, significantly improving the efficiency of on-site construction, reducing ineffective lifting and handling work, thereby saving labor and construction period.

[0040] (4) A portable drilling and cutting auxiliary device and a method of use of the present invention can more intuitively achieve high-precision drilling and cutting positioning through the cooperation of a fixed ring, a sliding ring and a limit ring on a column bracket, and by using a pressure plate assembly on a base to fix the workpiece to be processed; in addition, by adjusting the positions of the three rings on the column bracket, the processing depth can be flexibly adjusted, thereby ensuring the uniformity of the processing accuracy of the workpiece to be processed, improving the quality of drilling and cutting, and helping to reduce material waste and improve the economic benefits of construction; in addition, combined with the scale on the column bracket, the precise control of the drilling and cutting depth can be further ensured on the basis of smooth guidance, thereby reducing the dependence on the operating experience of the construction personnel, thereby reducing material waste and processing errors caused by improper operation.

[0051] Example 1

[0052] like Figures 1 to 4 As shown, this embodiment provides a portable drilling and cutting auxiliary device, including a base 3, a column bracket 4 and an operating bracket 5.

[0053] The lower end of the column bracket 4 is welded and fixed to the upper end surface of the base 3. The column bracket 4 is sleeved with a fixing ring 41, a sliding ring 42 and a limiting ring 43 from top to bottom. The fixing ring 41 and the limiting ring 43 are respectively locked and fixed to the column bracket 4 through a first locking eye ring 411 and a second locking eye ring 431. The sliding ring 42 is provided with a fixing eye ring 421. A reset spring 44 is provided between the fixing eye ring 421 and the first locking eye ring 411. The sliding ring 42 is movably connected to the fixing ring 41 through the reset spring 44. The sliding ring 42 can slide up and down between the fixing ring 41 and the limiting ring 43 along the central axis of the column bracket 4, thereby ensuring the path stability in the drilling and cutting processing operations and avoiding the manual error caused by the unstable operation of the construction personnel during the traditional handheld operation. The outer wall of the column bracket 4 is provided with a scale 45 to monitor the processing depth of drilling and cutting.

[0054] The right side wall of the fixing ring 41 is drilled with a first threaded through hole and equipped with a first locking eye ring 411. The first locking eye ring 411 is used to provide an upper fulcrum for the reset spring 44. The internal thread of the first threaded through hole and the thread specification of the first locking eye ring 411 are both M10; a third threaded through hole with a diameter of ￠20 is drilled at the C point of the front side wall of the fixing ring 41, and a shaft pin used as a fulcrum of the rotating shaft is provided in the third threaded through hole. The right side wall of the limit ring 43 is drilled with a second threaded through hole and equipped with a second locking eye ring 431. The locking eye ring is used to adjust and control the maximum depth of drilling or cutting, which can achieve more accurate drilling and cutting control, and improve the accuracy and quality of the workpiece 1 after drilling and cutting. A threaded blind hole is drilled on the right side wall of the sliding ring 42, and the fixed eye ring 421 is threadedly connected to the sliding ring 42 through the threaded blind hole. The fixed eye ring 421 is used to provide a lower fulcrum for the reset spring 44. The internal thread of the threaded blind hole and the thread specification of the second locking eye ring 431 are both M10.

[0055] The operating bracket 5 comprises an upper support rod 51, an intermediate support rod 52 and a lower support rod 53. An intermediate support rod 52 is provided between the upper support rod 51 and the lower support rod 53. The two ends of the intermediate support rod 52 are respectively hinged at point A of the rear end surface of the upper support rod 51 and point B of the front end surface of the lower support rod 53, so that the upper support rod 51 and the lower support rod 53 can be linked and moved through the hinge points at the two ends of the intermediate support rod 52. The left end of the upper support rod 51 is fixedly connected with a gripping portion 511, and the right end of the upper support rod 51 is hingedly fixed to point C of the front side wall of the fixing ring 41 through a pin shaft. The left end of the lower support rod 53 is equipped with a fixing clamp 531, which is annular and equipped with a locking member, and is used to clamp and fix the handheld drilling machine or the handheld cutting machine in an annular shape, and the right end of the lower support rod 53 is vertically welded and fixed to the left side wall of the sliding ring 42.

[0056] During operation, when force is applied downward to the upper support rod 51, the upper support rod 51 drives the lower support rod 53 to move downward through the hinge point of the middle support rod 52. Under the action of force applied to the operating bracket 5, the lower support rod 53 drives the sliding ring 42 to slide downward along the central axis of the column bracket 4, and after the force is released, the sliding ring 42 automatically resets upward along the reset spring 44 until the upper end surface of the sliding ring 42 is in contact with the lower end surface of the fixed ring 41, thereby improving the construction efficiency of drilling and cutting processing and saving manpower.

[0057] A drilling and cutting gap 32 is provided on the center line of the base 3, and the center of the fixing clamp 531 falls on the center line of the drilling and cutting gap 32, so as to allow the drilling and cutting head 22 of the drilling and cutting tool 21 to pass through during drilling and cutting. At the same time, after the drilling and cutting tool 21 is installed and before the workpiece 1 to be processed is placed, the drilling and cutting head 22 can be passed through the drilling and cutting gap 32 by pre-pressing downward to realize rapid angular positioning of the drilling machine and the cutting machine. The drilling and cutting tool 21 includes a portable drilling machine and a portable cutting machine, and the drilling and cutting head 22 includes a drill bit and a cutting disc.

[0058] The base 3 is provided with a pressure plate assembly 33 for fixing the workpiece 1 to be processed. The pressure plate assembly 33 includes a pressure plate bolt 331 and a pressure plate body 332. The longitudinal section of the pressure plate body 332 is zigzag-shaped and the side close to the workpiece 1 to be processed is a lower horizontal plate, which improves the structural strength of the pressure plate body 332 while ensuring a close fit with the workpiece 1 to be processed and enhancing the fixing effect. The pressure plate body 332 is movably connected to the pressure plate bolt 331 through a fastener, so that the pressure plate body 332 can be moved up and down along the central axis of the pressure plate bolt 331. The height can be adjusted to adapt to the workpieces 1 to be processed of different heights. At the same time, the combination of the pressure plate bolt 331 and the pressure plate body 332 can firmly fix the workpiece 1 to be processed to prevent movement or vibration during the drilling or cutting process, thereby ensuring stability and accuracy during the drilling and cutting process. The base 3 is provided with a threaded mounting hole, and the pressure plate bolt 331 is threadedly connected to the base 3 through the threaded mounting hole. The pressure plate body 332 is provided with an adjustment hole and is equipped with a fastener, so that the angle and height position of the pressure plate body 332 can be finely adjusted. , the height of the pressure plate body 332 can be accurately adjusted according to the specific needs of the workpiece 1 to be processed to ensure the best fixing effect. In this embodiment, the fastener adopts an adjusting nut 333, and the pressure plate body 332 is sleeved on the pressure plate bolt 331 through an adjusting hole. The pressure plate body 332 can rotate 360 ​​degrees around the central axis of the pressure plate bolt 331, and the height position of the pressure plate body 332 can be controlled and adjusted by adjusting nuts 333 arranged on the upper and lower sides of the adjusting hole; in this embodiment, the number of the pressure plate assemblies 33 is not less than two, and the The two pressure plate assemblies 33 are symmetrically arranged along the center line of the base 3 and are located at the left end of the base 3, which can prevent the workpiece from being offset or deformed due to uneven fixing force, provide balanced fixing force for drilling and cutting operations, and ensure the stability of the workpiece 1 to be processed during the processing. In addition, the farthest ends of the right sides of the two pressure plate bodies 332 exceed one-half of the drilling and cutting gap 32, which can provide a wider contact area for the workpiece 1 to be processed, thereby providing a more stable fixation during drilling and cutting, while ensuring that there will be no interference with the drilling and cutting gap 32.

[0059] A shock-absorbing pad 31 is provided at each of the four corners of the lower end surface of the base 3. The shock-absorbing pad 31 is made of rubber material and is used to eliminate operational vibration during drilling or cutting, ensure stability during operation, and thus improve the quality of drilling and cutting; and each corner of the base 3 is rounded to prevent damage during transportation.

[0060] In this embodiment, the base 3 is made of a steel plate with a thickness of 10 mm, a width of 250 mm, and a length of 500 mm; the column bracket 4 is made of a round tube with an outer diameter of ￠30 mm, and the height range of the round tube is 800-1000 mm, the fixed ring 41 is made of a round tube with an outer diameter of ￠36 mm and a length of 100 mm, the sliding ring 42 is made of a round tube with an outer diameter of ￠36 mm and a length of 150 mm, and the inner side walls of the fixed ring 41, the sliding ring 42, and the limit ring 43 are in contact with the column bracket 4. The outer wall is fitted together, which ensures the flexibility of sliding up and down and avoids the influence of displacement during the up and down sliding process. In other embodiments, when the inner diameters of the fixing ring 41, the sliding ring 42, and the limiting ring 43 are slightly larger than the outer diameter of the column bracket 4, a guide groove is also provided on the outer wall of the column bracket 4 to ensure that the orientation of the operating bracket 5 is always consistent with the length direction of the cutting gap. The first locking eye ring 411 and the second locking eye ring 431 are respectively locked and fixed in the guide groove through the first threaded through hole and the second threaded through hole. The upper support rod 51, the middle support rod 52 and the lower support rod 53 of the operating bracket 5 are all made of flat steel with a thickness of 10mm and a width of 25mm. The length of the upper support rod 51 is 400mm, and the gripping portion 511 adopts a hand-pressed knurled handle with a diameter of ￠30mm and a length of 150mm. The length of the upper support rod 51 is 120mm, and the length of the middle support rod 52 is determined according to the setting positions of point A and point B, which is about 150mm. Therefore, in the initial state where the upper end face of the sliding ring 42 is in contact with the lower end face of the fixing ring 41, the middle support rod 52 is perpendicular to the lower support rod 53; thereby, the total weight of the auxiliary device is about 50KG, which is convenient for moving to the ship to assist in drilling and cutting processes.

[0061] Example 2

[0062] like Figures 5 to 7 As shown, this embodiment provides a method for using a portable drilling and cutting auxiliary device using embodiment 1, which is used to assist a drilling tool 21 in drilling or cutting processing through a drilling head 22, wherein the drilling tool 21 includes a drilling machine and a cutting machine, and the drilling head 22 includes a drill bit and a cutting blade, including the following steps:

[0063] S1. Place the auxiliary device on the ship, and install the drilling and cutting tool 21 on the operating bracket 5 through the fixing clamp 531, so that the drilling and cutting head 22 at the lower end of the drilling and cutting tool 21 is vertically facing the base 3, and use the drilling and cutting gap 32 to determine and adjust the installation angle of the drilling and cutting tool 21 on the fixing clamp 531.

[0064] S1-1. Place the portable cutting and drilling auxiliary device on the ship so that the auxiliary device is in a horizontal or nearly horizontal position.

[0065] S1-2. The drilling and cutting tool 21 is locked and fixed on the lower bracket by the fixing clamp 531 to ensure that the portable drilling and cutting tool 21 will not cause shaking during the drilling or cutting process, and the power cord 23 of the drilling and cutting tool 21 avoids the drilling and cutting path. In this embodiment, since the lower support rod 53 is vertically fixed to the side wall of the sliding ring 42, the sliding ring 42 is concentric with the column bracket 4, and the column bracket 4 is vertically fixed on the base 3, the drilling and cutting head 22 located at the lower end of the drilling and cutting tool 21 fixed by the fixing clamp 531 is naturally perpendicular to the base 3.

[0066] S1-3. Use the gripping portion 511 to press the upper support rod 51 downward, and determine whether the installation positioning of the drilling tool 21 is accurate by observing whether the drilling head 22 at the lower end of the drilling tool 21 can pass vertically through the drilling gap 32 during pre-compression; if there is a deviation, adjust the fixed angle of the drilling tool 21 on the fixing clamp 531 until the drilling head 22 at the lower end of the drilling tool 21 can pass smoothly through the drilling gap 32, thereby ensuring that there will be no interference with the base 3 when it is necessary to penetrate the workpiece 1 to be processed, avoiding damage to the surface of the drilling head 22 or the base 3, reducing loss and increasing service life.

[0067] S2. According to the required drilling depth of the workpiece 1 to be processed, preliminarily determine the size of the drilling head 22 at the lower end of the drilling tool 21, and adjust the position of the fixing ring 41 on the column bracket 4 in combination with the height of the workpiece 1 to be processed.

[0068] S2-1. Determine the size of the drill head 22 according to the processing depth of the workpiece 1 to be processed, that is, determine the drill length of the drilling machine or the cutting blade diameter of the cutting machine, so that the drill length and the cutting blade diameter are not less than the processing depth. If the size of the drill head 22 is less than the processing depth, the drill head 22 needs to be replaced to ensure that the required processing depth can be reached during drilling and cutting, ensure the processing quality, and avoid uneven drilling and cutting edges caused by multiple drilling and cutting.

[0069] S2-2, loosen the first locking eye ring 411, adjust the position of the fixing ring 41 on the column bracket 4, so that the height of the lower end point of the drilling tool 21 from the upper end surface of the base 3 is higher than the height of the workpiece 1 to be processed, and ensure that the effective travel distance of the drilling tool 21 when pressed down can reach the processing depth of the workpiece 1 to be processed.

[0070] S2-3. Tighten the locking eye ring on the fixing ring 41 to lock and fix the fixing ring 41 on the column bracket 4 to ensure that the fixing ring 41 cannot move up and down.

[0071] S3, placing the workpiece 1 on the base 3, and adjusting the position of the workpiece 1 by pre-pressing the operating bracket 5 until the machining center of the workpiece 1 coincides with the lower end center of the drilling tool 21, and fixing it with the pressing plate assembly 33.

[0072] S3-1, first place the workpiece 1 on the base 3 at the drilling and cutting gap 32, press the grip 511 downward until the drilling head 22 contacts the upper surface of the workpiece 1, and then adjust the position of the workpiece 1 according to the deviation between the machining center of the workpiece 1 and the center of the drilling head 22. Specifically, when drilling, adjust the position of the workpiece 1 until the drilling center coincides with the drill center; when cutting, adjust the position of the workpiece 1 until the cutting line center coincides with the cutting blade center.

[0073] S3-2, fix the workpiece 1 using the pressure plate assembly 33: First, loosen the fasteners located on the upper and lower sides of the pressure plate body 332, adjust the height and rotation angle of the pressure plate body 332, until the contact area of ​​the pressure plate body 332 with the upper end surface of the workpiece 1 is the largest and avoids the machining center line; then, adjust and tighten the fasteners on the pressure plate from bottom to top, so that the pressure plate body 332 presses and fixes the workpiece 1. Specifically, first adjust the height of the fasteners located on the lower side of the pressure plate body 332 to be slightly lower than the current height of the pressure plate body 332, and then tighten the fasteners located on the lower side of the pressure plate body 332 downward until the pressure plate body 332 is clamped and fixed. At this time, the workpiece 1 is pressed and fixed with the upper end surface of the base 3.

[0074] S4. Pre-press downward until the drilling head 22 of the drilling tool 21 contacts the upper surface of the workpiece 1 to be processed, and record the scale 45 shown on the lower end surface of the sliding ring 42 on the column bracket 4 as the relative zero line. Take the relative zero line as the reference and adjust the position of the limit ring 43 on the column bracket 4 according to the processing depth.

[0075] S4-1. Press the holding part 511 downward again to make the lower end of the drilling head 22 of the drilling tool 21 contact the upper surface of the workpiece 1 to be processed, and re-observe and confirm whether the machining center of the workpiece 1 to be processed is consistent with the center of the lower end of the drilling tool 21: if there is a deviation, repeat step S3 to complete the position adjustment and fixation of the workpiece 1 to be processed; if there is no deviation, the scale 45 shown on the lower end surface of the sliding ring 42 on the column bracket 4 is the pre-load height X, and the scale 45 at this time is recorded as the relative zero line.

[0076] S4-2. Adjust the position of the limit ring 43 on the column bracket 4 based on the relative zero line: move the limit ring 43 to below the relative zero line and fix it so that the distance from the scale 45 on the upper end face of the limit ring 43 to the relative zero line is the same as the processing depth Y, that is, at this time, the distance from the upper end face of the limit ring 43 to the scale 45 on the lower end face of the sliding ring 42 is the sum of the pre-load height X and the processing depth Y, so as to ensure that when the gripping part 511 is continuously pressed downward, the limit ring 43 can be used to limit and remind the construction personnel to be in place, ensuring that the downward stroke meets the processing depth requirements. This is suitable for the situation where the same processing depth needs to be drilled on the same workpiece 1 to be processed or the situation where the same processing depth needs to be drilled on different workpieces 1 to be processed at the same height.

[0077] S5. Process the workpiece 1: slightly lift the holding portion 511 to leave a gap between the lower end of the drilling tool 21 and the upper surface of the workpiece 1, start the power supply of the drilling tool 21, press the holding portion 511 downward to apply force, and as the drilling head 22 of the drilling tool 21 moves downward, the sliding ring 42 also moves downward synchronously until it contacts and is limited by the limiting ring 43. At this time, the processing depth reaches the drilling requirement, release the holding portion 511 to unload the force, and under the contraction and reset action of the reset spring 44, the sliding ring 42 moves upward and automatically rebounds to reset, so that the drilling head 22 at the lower end of the drilling tool 21 is separated from the workpiece 1 that has been processed.

[0078] S6, check whether the drilling quality meets the drilling requirements, which include processing size, processing depth, and drilling edge smoothness: when drilling, the processing size is the hole size, and when drilling, the processing size is the length and width of the cut. If it does not meet the requirements, repeat step S5 for trimming; if it meets the requirements, complete the processing of the current workpiece 1 to be processed, continue the operation of the next workpiece 1 to be processed, and repeat steps S2 to S5 until all workpieces 1 to be processed have completed the processing operation.

[0079] When batch drilling or cutting processing is required, the workpieces 1 to be processed can be classified and sorted according to their heights and processing depths, and fixed processing can be started from the workpieces 1 with the highest height and the greatest processing depth, thereby avoiding the movement of the fixing ring 41 and the replacement of the drilling and cutting head 22. Only by adjusting the height of the limit ring 43 and the height of the pressure plate body 332, it is possible to adapt to different height dimensions and processing depth requirements, thereby improving the efficiency of drilling and cutting processing, speeding up the construction process, and saving time and labor costs.
