Description

Technical Field

[0001] The present invention relates to the technical field of drilling, and in particular to a drilling and grinding combined processing device and method based on a cable tray production line. Background Art

[0002] Cable trays, as core supporting structures for power, communications, rail transit, and other sectors, are experiencing continued market demand expansion alongside the development of new infrastructure. Cable tray production requires a series of processes, including profile forming, cutting, drilling, end-face polishing, and surface treatment. Drilling accuracy (which directly impacts installation compatibility) and end-face quality (which determines coating adhesion and corrosion resistance) are key indicators for determining product qualification rates.

[0003] For example, the patent document with the prior art publication number CN118699795A discloses a drilling and grinding device for valve processing, including a valve body, a processing table, a drilling mechanism, a grinding mechanism, a clamping mechanism, a power mechanism and a control system. The front and rear ends of the top of the processing table are respectively provided with a first processing position and a second processing position. The first processing position and the second processing position are both provided with two symmetrical limit openings, and the interior of the limit opening is fixedly connected with a first sliding rod. The patent document firstly positions and clamps the valve body through the set clamping mechanism, and then drives the clamping mechanism to move between the two processing positions and drives the drilling mechanism and the grinding mechanism to move, so that the clamping mechanism drives the clamped valve body to change position between the two processing positions, so that the drilling mechanism and the grinding mechanism drill and grind the valve body, which can improve the efficiency of valve processing.

[0004] The existing technology attempts to achieve a sequential connection between the drilling and grinding processes by installing a single clamping mechanism and moving it between two processing stations. However, in actual production applications, this design has exposed obvious process defects. Specifically, after the workpiece completes the drilling process, the inner wall of the hole will inevitably have processing burrs and excessive surface roughness, necessitating precision grinding. However, due to the structural design limitations of the grinding mechanism in the existing technology, it can only perform flat grinding operations on the outer surface of the workpiece and is unable to effectively perform deep processing inside the hole. More seriously, when the inner wall of the hole needs to be processed, the existing technology solution must go through the following inefficient process: first, move the workpiece to change its original positioning, then use dedicated inspection equipment to re-measure the hole axis parameters, and finally adjust the grinding mechanism angle for secondary positioning. This cumbersome repositioning process not only increases the processing time of each piece, but also causes cumulative errors due to multiple clamping and positioning, which increases the hole diameter tolerance and directly reduces the product yield. This process defect is particularly prominent in the field of precision component processing and seriously restricts the overall efficiency of the production line. To this end, the present application proposes a drilling and grinding combined processing equipment and method based on a cable tray production line. Summary of the Invention

[0013] Preferably, a plurality of air inlet grooves connected to the cavity are opened inside the receiving rod, and the outer surface of the receiving rod is slidably connected to a gas shell, and the gas shell is connected to the air pump through an air pipe. The gas shell is sleeved on the outer surface of the plurality of air inlet grooves for discharging gas through the air inlet grooves, and a retractable hose is fixedly connected to the inside of the air pipe.

[0014] Preferably, it also includes a pressure plate arranged above the workbench for fixing the cable tray body, the top of the workbench is fixedly connected to a partition positioning plate to support the side of the cable tray body, the top of the partition positioning plate is fixedly connected to a cylinder for driving the pressure plate to move, and the bottom of the pressure plate is fixedly connected to a plurality of rubber strips.

[0015] Preferably, the top of the pressure plate is fixedly connected to a positioning slide rod that is slidably connected to the partition positioning plate, and the pressure plate and the positioning slide rod are internally provided with cavities that are interconnected and used to store oil, and the top of the positioning slide rod is fixedly connected to a micro cylinder, and the output end of the micro cylinder extends to the interior of the positioning slide rod and is fixedly connected to a pressure head for squeezing oil.

[0016] Preferably, the interior of the positioning slide is slidably connected to a plug, the bottom of the pressure head is fixedly connected to a weighing scale, and the weighing scale is fixedly connected to the plug via a tension spring, and a narrowing opening is opened inside the positioning slide.

[0017] The present invention also provides a combined drilling and grinding processing method based on a cable tray production line, comprising the following steps:

[0018] S1. When using, first place the cable tray body on the top of the workbench;

[0019] S2. Operate the transmission assembly to allow the drill to penetrate the workpiece to drill a hole;

[0020] S3. After drilling, the drill bit continues to move so that the grinding disc is located in the hole, and then the air pump is turned on to supply air and cooperate with the grinding component to grind the hole.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The drill bit is used to drill holes in the cable tray body. Sliding brackets, connected to each side of the workbench, support the drill bit. Sliding the drill bit position changes, and the drive assembly automatically performs drilling, eliminating the need for frequent manual adjustments. This improves drilling efficiency and accuracy, and allows for multiple drilling operations to meet the processing needs of cable trays of varying specifications and requirements. The purge assembly and polishing assembly work together. During the polishing process, air pumped through the purge assembly cleans the hole, while the polishing disc, block, and disc simultaneously polish the hole in all directions. This multifunctional, simultaneous operation avoids the traditional step-by-step grinding-then-cleaning process, saving processing time and improving production tact. The combination of the electric guide rail and auxiliary frame ensures the stability and accuracy of the drill bit's movement, enabling precise control of the position and depth of the holes, achieving high levels of dimensional and positional accuracy, meeting the stringent requirements of cable tray installation. The driver continuously and stably rotates the drill bit, avoiding problems such as rough and eccentric holes caused by manual operation or unstable power, and ensuring the quality of the hole's inner wall. Sliding brackets sliding on both sides of the workbench allow for easy adjustment of the drill bit's position to accommodate the processing requirements of cable trays of varying specifications and sizes. Operators can quickly and accurately adjust the drill bit's position based on the actual processing situation, improving the equipment's flexibility and adaptability.

[0023] 2. The multiple rubber strips fixed to the bottom of the pressure plate are flexible. When in contact with the cable tray, they deform to a certain extent according to the surface shape of the cable tray, increasing the contact area and ensuring a more secure hold. Furthermore, the elasticity of the rubber prevents rigid impact between the pressure plate and the cable tray, minimizing surface damage and ensuring product quality. A divider plate divides the workbench into two stations, allowing two cable trays to be fixed and prepared for processing simultaneously. While processing a cable tray at one station, loading or unloading can be performed at the other, reducing equipment idle time and improving production efficiency. Furthermore, the two stations operate independently, minimizing mutual interference and facilitating process stability. A weighing scale accurately detects the pressure changes caused by the oil flow on the plug and converts the pressure value into an electrical signal, which is transmitted to the control system. The control system rapidly controls the micro-cylinder based on this signal, ensuring a fast response time and timely response to any vibration of the cable tray. This ensures that the rubber strips always provide appropriate support and maintains process stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a drilling and grinding combined processing equipment based on a cable tray production line, comprising a workbench 100 and a cable tray body 101 placed on top thereof. The workbench 100 is provided for the cable tray body 101 to be placed for subsequent processing operations.

[0034] It also includes a drill bit 200, which is used to drill holes in the cable tray body 101, and sliding brackets 201 that can be used to support the drill bit 200 are slidably connected on both sides of the workbench 100. The bottom of the sliding bracket 201 is provided with a transmission component that drives the drill bit 200 to rotate and move. By setting the drill bit 200, the cable tray body 101 can be drilled and cooperated with the transmission component to effectively realize automatic drilling, and it is slidably connected to the workbench 100 to change its position to realize multiple drilling.

[0035] It also includes an air pump 300, which is fixedly connected to the top of the sliding bracket 201 for conveying gas, and a receiving rod 204 connected to the drill bit 200 is provided below the sliding bracket 201, and a cavity 305 for gas to pass through is opened inside the receiving rod 204, and the outer surface of the drill bit 200 is fixedly connected to a grinding sheet 306 that can grind the inner wall of the hole, and grinding components for grinding both sides of the hole are provided on both sides of the grinding sheet 306, and a purge component for discharging gas according to the gas flow to clean the hole is provided inside the cavity 305. By setting the grinding component, the hole drilled by the drill bit 200 can be quickly polished without re-positioning, and the purge component can improve the efficiency of grinding while cleaning it.

[0036] Among them, the transmission assembly includes an electric rail 205 fixedly connected to the bottom of the sliding bracket 201, and the bottom of the electric rail 205 is slidably connected to an auxiliary frame 202 adapted thereto, and one side of the auxiliary frame 202 is fixedly connected to a driving member 203, and the output end of the driving member 203 is used to drive the drill bit 200 to rotate. By setting the driving member 203, the drill bit 200 can be continuously driven to rotate, and the cooperation with the electric rail 205 and the auxiliary frame 202 can continuously push the drill bit 200 to move at a uniform speed to achieve drilling work.

[0037] Among them, the grinding assembly includes multiple grooves opened on one side of the grinding plate 306, and the side plates 307 are slidably connected in the multiple grooves, and the grinding blocks 308 are fixedly connected to one side of the multiple side plates 307. A grinding plate is provided on the side of the receiving rod 204 close to the grinding plate 306. By setting the grinding plate 306, the inner wall of the hole can be polished, and by setting the grinding block 308, one side of the hole can be polished, and the grinding plate can be used to polish the other side of the hole.

[0038] Furthermore, the purge assembly includes a movable seat 310 arranged in the cavity 305, and one side of the movable seat 310 is rotatably connected to a plurality of cranks 309 rotatably connected to the side plate 307. The interior of the cavity 305 is slidably connected to a piston plate 311 adapted thereto, and the piston plate 311 is fixedly connected to the movable seat 310. By setting up the purge assembly, the gas in the air pump 300 can be output through the receiving rod 204, thereby achieving purging while grinding, improving the efficiency of grinding and avoiding subsequent cleaning.

[0039] It is worth mentioning that the interior of the grinding disc 306 is provided with a plurality of vertical exhaust grooves 313 for gas discharge, the interior of the receiving rod 204 is provided with a plurality of side exhaust grooves 314 connected to the cavity 305 for gas discharge, the inner wall of the cavity 305 is provided with a plurality of connecting grooves 312 connected to the vertical exhaust grooves 313, the interior of the receiving rod 204 is provided with a plurality of air inlet grooves 304 connected to the cavity 305, the outer surface of the receiving rod 204 is slidably connected to the gas shell 303, and the gas shell 303 is connected to the air pump 300 through the gas pipe 301, the gas shell 303 is sleeved on the outer surface of the plurality of air inlet grooves 304 for discharging gas through the air inlet grooves 304, and the interior of the gas pipe 301 is fixedly connected There is a retractable hose 302, in which the grinding plate 306 is consistent with the diameter of the drill bit 200. After the drill bit 200 completes drilling, the continuous driving of the electric rail 205 will enable the drill bit 200 to completely pass through the hole so that the grinding plate 306 is located on the inner wall of the hole. When the gas is delivered to the inside of the cavity 305, it will push the piston plate 311 to move so that it is placed inside the connecting groove 312, so that part of the gas passes through the connecting groove 312 and crosses the piston plate 311, and is discharged through the vertical exhaust groove 313 to achieve cleaning. The movement of the movable seat 310 will drive the crank 309 to tilt so that multiple side plates 307 can be expanded, and multiple grinding blocks 308 can be pressed against one side of the hole to achieve comprehensive grinding.

[0040] Specifically, the driving member 203 is operated to drive the drill bit 200 to rotate, and at the same time, the electric guide rail 205 is turned on to drive the auxiliary frame 202 to move so that the drill bit 200 rotates and approaches one side of the cable tray body 101 to drill a hole. When the drill bit 200 completes drilling, the electric guide rail 205 will continue to move until the grinding plate 306 is located in the hole. Then the air pump 300 is turned on to deliver gas to the gas pipe 301. At this time, the gas passes through the gas shell 303 and passes through multiple air inlet grooves 304 into the interior of the cavity 305. The gas gradually increases in the cavity 305, which will push the piston plate 311 to move. At the same time, part of the gas is discharged through the side exhaust. The air groove 314 discharges the side of the purging hole, and the piston plate 311, driven by the air pressure, moves the transmission moving seat 310 so that the multiple cranks 309 are tilted, and then the multiple side plates 307 are unfolded, so that the multiple side plates 307 are located on one side of the cable tray body 101. At this time, the piston plate 311 will pass over the connecting groove 312 so that part of the gas passes through the connecting groove 312 and is discharged from the vertical exhaust groove 313. Thereafter, the continuous transmission of the driving member 203 will cause the grinding plate 306 to grind the inner wall of the hole, and the grinding block 308 will grind one side of the hole, and one side of the receiving rod 204 will grind the other side of the hole.

[0041] In summary, the drill bit 200 is used to perform drilling operations on the cable tray body 101. The sliding brackets 201 slidably connected on both sides of the workbench 100 can support the drill bit 200. The position of the drill bit 200 is changed by sliding, and the transmission component is used to realize automatic drilling, eliminating the need for frequent manual adjustment of the drill bit position, improving drilling efficiency and accuracy, and achieving multiple drilling operations to meet the processing requirements of cable trays of different specifications and requirements. The purge component and the polishing component work together. During the polishing process, the gas delivered by the air pump 300 cleans the holes through the purge component, while the polishing disc 306, the polishing block 308 and the polishing disc polish the holes in all directions. This multifunctional and synchronous method avoids the step-by-step operation of grinding first and then cleaning in traditional processing, saving processing time and improving production rhythm. The cooperation between the electric guide rail 205 and the auxiliary frame 202 ensures the stability and accuracy of the movement of the drill bit 200, and can accurately control the position and depth of the hole, so that the dimensional accuracy and position accuracy of the hole reach a high level, meeting the strict requirements of cable tray installation. The driving member 203 continuously and stably drives the drill bit 200 to rotate, avoiding problems such as rough hole wall and eccentricity caused by manual operation or unstable power, and ensuring the quality of the inner wall of the hole. The sliding bracket 201 slidably connected on both sides of the workbench 100 can easily adjust the position of the drill bit 200 to adapt to the processing requirements of cable trays of different specifications and sizes. The operator can quickly and accurately adjust the position of the drill bit 200 according to the actual processing situation, improving the flexibility and adaptability of the equipment.

[0042] Example 2: Please refer to Figure 1-Figure 7 The present invention also provides a technical solution, which is different from the technical solution of embodiment 1: a drilling and grinding combined processing equipment based on a cable tray production line, further comprising a pressing plate 400 arranged above the workbench 100 for fixing the cable tray body 101, and a partition positioning plate 401 is fixedly connected to the top of the workbench 100 to support the side of the cable tray body 101, and a cylinder 410 is fixedly connected to the top of the partition positioning plate 401 to drive the pressing plate 400 to move, and a plurality of rubber strips 402 are fixedly connected to the bottom of the pressing plate 400. By setting the partition positioning plate 401, the workbench 100 can be divided into two workstations, thereby improving efficiency and facilitating support and limitation of the cable tray body 101. The setting of the pressing plate 400 can further fix the cable tray body 101, and the plurality of rubber strips 402 are elastic and can suppress the vibration of the cable tray body 101.

[0043] Among them, the top of the pressure plate 400 is fixedly connected to a positioning slide 403 that is slidably connected to the partition positioning plate 401, and the inside of the pressure plate 400 and the positioning slide 403 are provided with cavities that are interconnected and used to store oil, and the top of the positioning slide 403 is fixedly connected to a micro cylinder 405, and the output end of the micro cylinder 405 extends to the inside of the positioning slide 403 and is fixedly connected to a pressure head 406 for squeezing oil. By arranging oil in the pressure plate 400 and the positioning slide 403, the supporting strength of the rubber strip 402 can be increased, and when it is vibrated, the vibration force is transmitted to the oil to achieve energy dispersion.

[0044] The interior of the positioning slide 403 is slidably connected to a plug 407, and the bottom of the pressure head 406 is fixedly connected to a weighing scale 408, and the weighing scale 408 is fixedly connected to the plug 407 through a tension spring 409. A narrowing opening 404 is opened inside the positioning slide 403. At the same time, when it is subjected to a strong shaking force, the transmission oil will move and squeeze the plug 407, thereby pushing the tension spring 409 to contract under force. At this time, the detection value of the weighing scale 408 will increase, and then an electrical signal will be transmitted to make the micro cylinder 405 run to push the pressure head 406 downward and squeeze the oil in the reverse direction, providing a stronger and more powerful support force for the rubber strip 402.

[0045] Specifically, the cylinder 410 is turned on to drive the pressure plate 400 downward so that it contacts the top of the cable tray body 101 for fixation. At this time, multiple rubber strips 402 contact the top of the cable tray body 101, and the interior of the positioning slide 403 and the pressure plate 400 are filled with oil. As the cable tray body 101 shakes, the transmission rubber strip 402 contracts and squeezes the oil inside it, so that the oil is forced to flow through the narrowed mouth 404 to the interior of the positioning slide 403. At this time, the oil will push the plug 407 and squeeze the tension spring 409, so that the pressure value detected by the weighing meter 408 increases. At this time, the fast-transmitting micro cylinder 405 runs and squeezes the pressure head 406 downward, thereby driving the plug 407 downward to suppress the flow of oil and provide support for the rubber strip 402.

[0046] In summary, the multiple rubber strips 402 fixedly connected to the bottom of the pressure plate 400 are elastic. When in contact with the cable tray body 101, they can deform to a certain extent according to the surface shape of the cable tray body 101, increase the contact area, and make the fixation more secure. At the same time, the elasticity of the rubber can avoid rigid collision between the pressure plate 400 and the cable tray body 101, reduce damage to the surface of the cable tray body 101, and ensure the appearance quality of the product. The partition positioning plate 401 divides the workbench 100 into two stations, and can fix and prepare the two cable tray bodies 101 at the same time. When the cable tray body 101 on one station is being processed, the other station can perform loading or unloading operations, reducing the idle time of the equipment and improving production efficiency. At the same time, the two stations operate independently and have little influence on each other, which is conducive to maintaining the stability of the processing process. The weighing meter 408 can accurately detect the pressure changes caused by the flow of oil on the plug 407, and convert the pressure value into an electrical signal and transmit it to the control system. The control system quickly controls the action of the micro cylinder 405 according to the electrical signal. The whole process has a fast response speed and can react to the vibration of the cable tray body 101 in time, ensuring that the rubber pressure strip 402 always provides appropriate support strength and ensures the stability of the processing process.

[0047] Example 3: Please refer to Figure 1-Figure 7 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a drilling and grinding combined processing method based on a cable tray production line, comprising the following steps:

[0048] S1. When in use, first place the cable tray body 101 on the top of the workbench 100 and below the pressing plate 400;

[0049] S2. The pressure plate 400 is driven downward by opening the cylinder 410 so that it contacts the top of the cable tray body 101 for fixation. At this time, multiple rubber strips 402 contact the top of the cable tray body 101, and the interior of the positioning slide 403 and the pressure plate 400 is filled with oil. As the cable tray body 101 shakes, the transmission rubber strip 402 contracts and squeezes the oil inside, so that the oil is forced to flow through the narrowed opening 404 to the interior of the positioning slide 403. At this time, the oil will push the plug 407 and squeeze the tension spring 409, so that the pressure value detected by the weighing meter 408 increases. At this time, the fast-transmitting micro-cylinder 405 runs and squeezes the pressure head 406 downward, thereby driving the plug 407 downward to suppress the flow of oil and provide support for the rubber strip 402.

[0050] S3, operate the driving member 203 at the same time to drive the drill bit 200 to rotate, and at the same time turn on the electric guide rail 205 to drive the auxiliary frame 202 to move so that the drill bit 200 rotates and approaches one side of the cable tray body 101 to drill it. When the drill bit 200 finishes drilling, the electric guide rail 205 will continue to move until the grinding plate 306 is located in the hole. Then turn on the air pump 300 to deliver gas to the gas pipe 301. At this time, the gas passes through the gas shell 303 and passes through multiple air inlet grooves 304 into the interior of the cavity 305. The gas gradually increases in the cavity 305 and pushes the piston plate 311 to move. At the same time, part of the gas is discharged through the side exhaust. The air groove 314 discharges the side of the purging hole, and the piston plate 311, driven by the air pressure, moves the transmission moving seat 310 so that the multiple cranks 309 are tilted, and then the multiple side plates 307 are unfolded, so that the multiple side plates 307 are located on one side of the cable tray body 101. At this time, the piston plate 311 will pass over the connecting groove 312 so that part of the gas passes through the connecting groove 312 and is discharged from the vertical exhaust groove 313. Thereafter, the continuous transmission of the driving member 203 will cause the grinding plate 306 to grind the inner wall of the hole, and the grinding block 308 will grind one side of the hole, and one side of the receiving rod 204 will grind the other side of the hole.
