Description

Technical Field

[0001] The invention relates to the technical field of metal processing machinery manufacturing, and in particular to a highway traffic guardrail processing device. Background Art

[0002] In the highway guardrail system, the flange column plays a vital role in the stability of the overall structure. The flange column consists of a flange plate at the bottom and a column at the top. In order to ensure that the flange column can be firmly installed, four screw holes need to be accurately drilled at the position of the flange plate. However, in terms of the handling of debris generated during the drilling process of the flange column, the existing technical solutions face a series of challenges and need to be improved urgently.

[0003] Currently, many processing equipment rely on vacuum devices to collect debris generated during drilling. Although this vacuum mechanism can clean up debris to a certain extent, in actual operation, the suction force of the vacuum cleaner is difficult to flexibly adjust according to different working conditions (such as different materials, drilling speed, etc.) to match the different magnitudes and distributions of debris generated in an instant. This leads to the situation that in some cases, especially when drilling operations generate a large amount of debris, existing vacuum equipment may not be able to effectively remove all debris in a timely manner, resulting in the problem of residual debris on the workbench surface or in the processing environment.

[0004] Another common solution is to use air pipes to blow away the debris from the workbench, hoping to clean it up uniformly later. However, this method has obvious limitations: first, blowing may cause the debris to fly disorderly, increasing the difficulty of control and the potential risk of damage to surrounding equipment, and aggravating the degree of pollution in the working environment; second, the debris blown off the workbench is easy to fall back to key parts, such as guide rails or screws, which will not only accelerate the wear of mechanical parts, but also affect the accuracy and service life of the equipment. Summary of the invention

[0005] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a highway traffic guardrail processing device.

[0006] The technical implementation scheme of the present invention is: a highway traffic guardrail processing device, including a base, an electric push rod, a connecting block, a drilling machine, a workbench, a magnet ring, a limit assembly and a cleaning assembly. The electric push rod is symmetrically installed on the top of the base through a support seat, and the electric push rod telescopic rod is connected to a connecting block, and a drilling machine is installed on the connecting block. The drilling machine is equipped with two drill bits symmetrically distributed front and back. A workbench is connected to the middle of the top of the base, and discharge holes are opened on the workbench for four holes to be drilled in the flange plate. A blanking trough is arranged inside the base, and the discharge holes and the blanking trough are connected to each other. Magnet rings are respectively connected on both sides of the connecting block, and the four magnet rings are respectively located on the outside of the drilling machine drill bit. A limit assembly is arranged on the top of the base, and a cleaning assembly is arranged on the drilling machine.

[0007] Furthermore, the magnet ring is made of high-performance NdFeB permanent magnet material.

[0008] Furthermore, the limiting assembly includes a slide rail, a side clamp, a U-shaped block, an arc-shaped clamp and a return spring. The slide rails are symmetrically connected on both sides of the top of the base, and the side clamps are slidably connected between the two slide rails on the left and right sides. The return springs are connected between the front and rear ends of the side clamps and the slide rails. The middle part of the side clamp is connected to the U-shaped block, and the connecting block and the U-shaped block are slidably matched. The top of the drilling machine is respectively connected to the arc-shaped clamps.

[0009] Furthermore, the cleaning assembly includes an inclined plate, a lifting block, a stretching spring and a cleaning scraper ring. The lifting block is symmetrically and slidingly connected to the outside of the drilling machine, and the cleaning scraper ring is connected to the bottom of the lifting block. The cleaning scraper ring slides with the inner side of the corresponding magnet ring. A stretching spring is connected between the lifting block and the drilling machine, and the inclined plate is symmetrically connected to the top of the side clamp. The lifting block is a triangular structure, and its inclined surface is in contact with the inclined plate. In the initial state, the inclined plate resists the lifting block, so that the stretching spring is in a stretched state.

[0010] Furthermore, the inner edge of the cleaning scraper ring is designed to be a sharp edge structure with a certain elasticity.

[0011] Furthermore, a slot is provided on the side clamping plate at a position aligned with the cleaning scraper ring, a cleaning hole is provided on the base at a position aligned with the cleaning scraper ring, the cleaning hole is aligned with the slot, and the cleaning hole is communicated with the blanking chute.

[0012] Furthermore, it also includes a guide rod, a slider, a hinge rod, a center block and a return spring. The top of the base is respectively connected to the guide rods at the front and rear sides of the two side clamps. Each guide rod is slidably connected to the slider. A return spring is connected between the slider and the guide rod, and the slider is in abutment with the side clamp. The inner side of the slider is rotatably connected to the hinge rod, and the inner sides of two adjacent hinge rods are rotatably connected to the center block. The center block is tightly fitted to the top surface of the base, and the two center blocks are located at the front and rear sides of the workbench.

[0013] Furthermore, it also includes a pressure plate, a torsion spring, a top block and a compression spring. The pressure plate is rotatably connected to the middle of the inner side of the side clamp, the torsion spring is connected between the two ends of the pressure plate and the side clamp, the top block is slidably connected to the middle of the inner side of the side clamp, the compression spring is connected between the top block and the side clamp, the pressure plate is located on the outside of the top block, and the two are in contact and cooperate with each other.

[0014] Beneficial effects: 1. The discharge hole on the workbench is interconnected with the blanking trough in the base. The waste chips generated by drilling fall into the blanking trough through the discharge hole and can be quickly collected with the collection frame. At the same time, the magnet ring on the connecting block can absorb small debris to prevent it from affecting the drilling accuracy, and the cleaning component can automatically clean the magnet ring to ensure the adsorption effect. The entire debris processing process is efficient and highly automated.

[0015] 2. The drilling machine equipped with the device is equipped with two symmetrical drill bits. The drilling machines on both sides work together to drill holes in the four corners of the flange plate of the flange column at one time, which greatly improves the drilling efficiency and meets the mass production needs of highway traffic guardrail processing.

[0016] 3. The side clamps and arc clamps in the limit assembly clamp and limit the flange plate and column of the flange column respectively to ensure the stability of the workpiece during processing. In addition, the newly added centering limit structure composed of the slider, hinged rod and centering block can automatically push the centering block to center the flange column on the workbench during the clamping process of the side clamps, ensuring that the position of the flange plate to be punched is accurately aligned with the discharge hole, thereby improving the accuracy of the punching position.

[0017] 4. The pressure plate, torsion spring, top block and compression spring on the inner side of the side clamping plate form a multi-directional limit assembly. When the side clamping plate clamps the flange plate, the top block first contacts the flange plate and pushes the pressure plate to rotate to the horizontal state, and the flange plate is limited in multiple directions from the side and upper positions, which further enhances the stability of the flange plate during the drilling of the flange column and ensures the processing accuracy.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0031] Embodiment 1: A highway traffic guardrail processing device, such as Figure 1-Figure 7As shown, it includes a base 1, an electric push rod 101, a connecting block 102, a drilling machine 103, a workbench 104, a magnet ring 107, a limit assembly and a cleaning assembly. The electric push rod 101 is symmetrically installed on the top of the base 1 through a support seat. The connecting block 102 is connected to the telescopic rod of the electric push rod 101. The drilling machine 103 is installed on the connecting block 102. The drilling machine 103 is equipped with two drill bits symmetrically distributed front and back, which can efficiently realize the drilling operation on the four corners of the flange plate of the flange column 108. A workbench 104 is detachably installed in the middle of the top of the base 1 for receiving the flange column 108 for processing. Discharge holes 105 are accurately opened on the workbench 104 for the four places to be drilled in the flange plate. The size of the discharge hole 105 is larger than the size of the hole to be drilled in the flange plate to ensure that the waste chips generated by the drilling can pass smoothly. A blanking trough 106 is arranged inside the base 1 to discharge The material hole 105 is connected with the material chute 106, and the bottom surface of the material chute 106 is designed to be inclined, so that the internal waste chips can naturally slide out of the base 1 along the inclined surface to the rear side. By placing a collection frame at the corresponding position, the waste chips can be quickly collected conveniently. Magnet rings 107 are welded on the front and rear sides of the connecting block 102, and the four magnet rings 107 are respectively located on the outside of the drill bit of the drilling machine 103. When the drill bit of the drilling machine 103 is raised and lowered to drill the flange plate of the flange column 108, the magnetic properties of the metal are used to absorb small debris on the magnet ring 107, which effectively prevents the debris from affecting the drilling accuracy. The magnet ring 107 is made of high-performance neodymium iron boron permanent magnet material, which has an extremely high magnetic energy product and can generate a strong magnetic field strength to ensure that small metal debris can be effectively absorbed during the drilling process. A limit assembly is provided on the top of the base 1, and a cleaning assembly is provided on the drilling machine 103.

[0032] like Figure 1 and Figure 5-Figure 6 As shown, the limiting assembly includes a slide rail 201, a side clamp 202, a U-shaped block 203, an arc-shaped clamp 204 and a return spring 205. The left and right sides of the top of the base 1 are symmetrically connected to the slide rails 201 by screws. The two slide rails 201 on the left and right sides are respectively slidably connected with side clamps 202. The side clamps 202 are used to firmly clamp the flange plate of the flange column 108. The front and rear ends of the side clamps 202 are connected to the slide rails 201 with return springs 205 to provide elastic reset force. A U-shaped block 203 is welded to the middle of the side clamp 202. The connecting block 102 and the U-shaped block 203 are slidably matched to achieve precise position transfer. The top of the drilling machine 103 is respectively connected with arc-shaped clamps 204 that fit the outer surface shape of the column by bolts for limiting and clamping the column of the flange column 108.

[0033] like Figure 4 and Figure 6-Figure 7As shown, the cleaning component includes an inclined plate 301, a lifting block 302, a tension spring 303 and a cleaning scraper ring 304. The lifting block 302 is symmetrically slidably connected to the outer side of the drilling machine 103. The cleaning scraper ring 304 is connected to the bottom of the lifting block 302. The cleaning scraper ring 304 slides with the corresponding inner side of the magnet ring 107, and can scrape the debris adsorbed on the inner side of the magnet ring 107 downward to clean the magnet ring 107. The inner edge of the cleaning scraper ring 304 is designed to be sharp and has a certain elasticity. The blade structure can not only fit closely to the inner side of the magnet ring 107 to ensure that there is no omission when scraping debris, but also use its own elasticity to adapt to the slight unevenness that may exist on the surface of the magnet ring 107 to improve the scraping effect. A tension spring 303 is connected between the machine 103 to provide an upward pulling force. An inclined plate 301 is symmetrically connected to the top of the side clamping plate 202. The lifting block 302 is a triangular structure, and its inclined surface is in contact with the inclined plate 301. In the initial state, the inclined plate 301 is against the lifting block 302, so that the tension spring 303 is in a tensioned state. A slot is provided on the side clamping plate 202 at a position aligned with the cleaning scraper ring 304 for discharging metal debris. A cleaning hole 305 is provided on the base 1 at a position aligned with the cleaning scraper ring 304. The cleaning hole 305 is aligned with the slot, and the cleaning hole 305 is communicated with the blanking chute 106 to ensure that after the cleaning scraper ring 304 scrapes and cleans the debris on the magnet ring 107, the debris can fall into the blanking chute 106 through the slot and the cleaning hole 305.

[0034] When drilling the flange column 108, firstly, the flange column 108 is accurately placed in the center of the workbench 104 to ensure that the four holes to be drilled on the flange plate of the flange column 108 are accurately aligned with the discharge hole 105. At this time, the entire processing device enters the waiting state, and then the electric push rod 101 is started, and the telescopic rod of the electric push rod 101 extends to drive the connecting block 102, the drilling machine 103, the arc clamping plate 204, the magnet ring 107, the lifting block 302 and the cleaning scraper ring 304 to move inward synchronously. Since the inclined plate 301 initially abuts against the lifting block 302, the tension spring 303 is in a stretched state. When the lifting block 302 moves inward, the two are disengaged, and the tension spring 303 immediately rebounds and recovers. The cleaning scraper ring 304 is in the position, driving the lifting block 302 and the cleaning scraper ring 304 to move upward, and the cleaning scraper ring 304 immediately breaks away from the contact with the inner side of the magnet ring 107, and the magnet ring 107 enters the working state to absorb the debris. When the connecting block 102 moves inwardly until it contacts the inner side of the U-shaped block 203, the connecting block 102 will push the U-shaped block 203 to move inwardly, and the U-shaped block 203 drives the side clamping plate 202 to move inwardly along the slide rail 201, and the return spring 205 is stretched accordingly, and the inclined plate 301 moves synchronously, and the side clamping plate 202 moves inwardly to realize the clamping limit of the left and right sides of the flange plate. At the same time, the arc clamping plate 204 tightly clamps the column of the flange column 108 to ensure that the workpiece remains stable during the drilling process.

[0035] After all components are moved into place, the electric push rod 101 is turned off and the drilling machine 103 is started. The drilling machine 103 efficiently drills holes at the four corners of the flange plate by lifting and rotating the drill bit. Most of the metal debris generated during the drilling process is discharged into the blanking chute 106 through the discharge hole 105, and some fine metal debris is adsorbed on the magnet ring 107 due to the metal magnetism, which effectively prevents these debris from remaining on the surface of the flange plate and affecting the drilling accuracy. When the flange plate is drilled, Turn off the drilling machine 103, control the telescopic rod of the electric push rod 101 to retract and reset, drive the connecting block 102, the drilling machine 103, the arc-shaped clamping plate 204, the lifting block 302 and the cleaning scraper ring 304 to move outward and reset synchronously, the return spring 205 rebounds and resets, drives the side clamping plate 202 and the inclined plate 301 to move outward along the slide rail 201, and because the connecting block 102 is against the inner side of the U-shaped block 203, the side clamping plate 202 and the connecting block 102 maintain their position and move synchronously to reset. When the side clamp 202 moves and resets to its position, the connection block 102, the drilling machine 103 and the lifting block 302 continue to move outward, and the inclined surface of the lifting block 302 cooperates with the inclined plate 301 to force the lifting block 302 to move downward, and the tension spring 303 is further stretched, and the lifting block 302 drives the cleaning scraper ring 304 to move downward, and the cleaning scraper ring 304 moves along the inner side of the magnet ring 107 to scrape and clean the metal debris adsorbed on the inner side of the magnet ring 107. The metal debris enters the blanking chute 106 through the notch of the side clamp 202 and the cleaning hole 305, realizing automatic cleaning of the metal debris. At this point, a complete processing and cleaning cycle is completed, waiting for the drilling of the next flange column 108.

[0036] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 8-Figure 9 As shown, it also includes a guide rod 401, a slider 402, a hinge rod 403, a center block 404 and a reset spring 405. The guide rods 401 are respectively welded on the top of the base 1 at the front and rear sides of the two side clamps 202. Each guide rod 401 is slidably connected to the slider 402. A reset spring 405 is connected between the slider 402 and the guide rod 401, and the slider 402 is in abutment with the side clamp 202, so that the reset spring 405 is in a stretched state. The inner side of the slider 402 is rotatably connected to the hinge rod 403, and the inner sides of the two adjacent hinge rods 403 are rotatably connected to the center block 404. The center block 404 is tightly fitted to the top surface of the base 1, and the two center blocks 404 are located at the front and rear sides of the workbench 104.

[0037] When working, in the initial state, the side clamping plate 202 is against the slider 402, and the reset spring 405 is in a stretched state. When the side clamping plate 202 moves inward to clamp the flange plate of the flange column 108, the side clamping plate 202 unloads the force on the slider 402, and the slider 402 moves inward along the guide rod 401 under the reset action of the reset spring 405. The guide rod 401 pushes the hinge rod 403 to rotate, so that the corresponding two hinge rods 403 cooperate to drive the centering block 404 to move inward along the top surface of the base 1, and then the flange column 108 on the workbench 104 is centered. This ensures that the flange column 108 is in the middle position of the workbench 104, and applies clamping force to the front and rear sides of the flange column 108, so that the position of the flange plate of the flange column 108 to be punched can be accurately aligned with the discharge hole 105, ensuring the accuracy of the punching position. When the flange column 108 is processed, the side clamp 202 moves outward and resets. When it moves to contact the slider 402, it pushes the slider 402 to move outward, and the reset spring 405 is stretched accordingly. The slider 402 drives the hinge rod 403 to reverse and reset, and the hinge rod 403 drives the center block 404 to move outward and reset, thereby releasing the limit on the flange column 108.

[0038] like Figure 10-11 As shown, it also includes a pressure plate 501, a torsion spring 502, a top block 503 and a compression spring 504. The pressure plate 501 is rotatably connected to the middle of the inner side of the side clamp 202, and the torsion spring 502 is connected between the front and rear ends of the pressure plate 501 and the side clamp 202. The top block 503 is slidably connected to the middle of the inner side of the side clamp 202, and the compression spring 504 is connected between the top block 503 and the side clamp 202. The pressure plate 501 is located on the outside of the top block 503, the two are in contact and cooperate with each other, and the position of the inner side surface of the top block 503 exceeds the position of the inner side surface of the side clamp 202.

[0039] When the side clamping plate 202 moves inward to clamp the flange plate of the flange column 108 , the pressing plate 501 and the lifting block 503 move synchronously. The top block 503 will first abut against the side of the flange plate. As the side clamping plate 202 continues to move, the top block 503 will be forced to move outward, and the compression spring 504 will be compressed. The top block 503 will push the lower end of the pressure plate 501 outward, causing the pressure plate 501 to rotate 90 degrees to a horizontal state, and the torsion spring 502 will deform accordingly. After the side clamping plate 202 moves to completely clamp the flange plate, the pressure plate 501 rotates 90 degrees to clamp the top of the flange plate. In this way, the side clamping plate 202 cooperates with the pressure plate 501 to achieve multi-directional limiting of the side and upper positions of the flange plate, effectively ensuring the stability of the flange plate during the drilling of the flange column 108. When the flange plate is drilled, the side clamping plate 202 moves outward to reset, and the compression spring 504 will also rebound and reset, driving the top block 503 to move inward. After the pressure plate 501 is no longer subjected to force, it is reversed and reset to a vertical state under the reset action of the torsion spring 502 , and then the pressure plate 501 and the top block 503 continue to move and reset along with the side clamping plate 202 .

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
