Description

Technical Field

[0001] This utility model relates to the field of clamping component technology, specifically a clamping component for machining holes in steel rails. Background Technology

[0002] Rail drilling refers to the process of drilling holes at specific locations on a rail. Its main purpose is to meet the needs of rail connection and equipment installation. This process may seem simple, but it actually requires extremely high technical skills. It is necessary to comprehensively consider the material of the rail, its stress characteristics, and long-term service conditions. When drilling rail holes, the rail needs to be clamped and fixed, which requires the use of rail drilling clamping components. Rail drilling clamping components are mechanical devices specifically designed to fix the position of the rail for precise drilling. These components have strong clamping force and precise positioning capabilities.

[0003] Patent document CN222344905U discloses a fixture for machining intermediate holes, which includes a hollow base, a clamping structure for hole machining on the top of the hollow base, and a chip collection structure on the outside of the hollow base. The clamping structure includes two support plates fixedly installed on the top of the hollow base, and a movable insert plate slidably installed between the two support plates. This fixture for machining intermediate holes supports and lifts multiple workpieces through the movable insert plate and multiple holding racks. Then, the advance and retraction cylinder unfolds to push the movable insert plate and multiple workpieces to the left. When two infrared sensors detect that a workpiece is between the two movable clamps, they control the two movable clamps to clamp the workpiece. After the workpiece is drilled, the advance and retraction cylinder can be controlled to unfold again to push a second workpiece to the left and be clamped by the two movable clamps. This automatic feeding and clamping reduces manual operation steps, thereby achieving a high clamping production efficiency.

[0004] However, the aforementioned open-source fixture for machining holes mainly focuses on achieving high clamping efficiency, but it is inconvenient to collect the waste chips generated during drilling.

[0005] Therefore, it is necessary to develop a waste collection mechanism to collect the waste generated during drilling. Summary of the Invention

[0006] The purpose of this utility model is to provide a clamping assembly for machining rail holes, so as to solve the technical problem mentioned in the background art of making the clamping assembly for machining rail holes have a waste chip collection function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping assembly for drilling holes in steel rails, comprising: a base plate, a clamping block, a drilling platform, and a drilling groove, wherein the bottom of the drilling platform is provided with a waste chip collection mechanism, which is used to collect waste chips generated during drilling;

[0008] The waste collection mechanism includes a waste collection frame and a functional column. The inner wall of the hole-making groove is provided with a feeding trough. The waste collection frame is located at the bottom of the hole-making platform. The functional column is installed at the bottom of the hole-making platform. A bearing is embedded in the bottom of the functional column. A limit plate is installed on the outer wall of the bearing. A rubber protective pad is embedded in the outer wall of the limit plate. A locking groove is provided at the top of the limit plate. A plate is installed on the outer wall of the functional column. A sliding rod is installed at the bottom of the plate. A sliding plate is installed around the outer wall of the sliding rod. A spring is installed at the bottom of the plate, and one end of the spring extends to the outer wall of the sliding plate. A locking block is installed on the outer wall of the sliding plate.

[0009] Preferably, an electric slide rail is installed on the top of the base plate, a clamping block is installed at the output end of the electric slide rail, a fixing plate is installed on the top of the base plate, a control box is installed on the outer wall of the fixing plate, the hole-making table is located on the outer wall of the base plate, and a hole-making groove is provided on the top of the hole-making table.

[0010] Preferably, the top of the drilling platform is provided with a protective mechanism to prevent debris from splashing during drilling.

[0011] Preferably, the protective mechanism includes a protective cover, an opening, and a perforation groove. The protective cover is located on the top of the perforation table, the outer wall of the protective cover has an opening that extends through the interior of the protective cover, and the top of the protective cover has a perforation groove.

[0012] Preferably, the outer wall of the protective cover is equipped with an assembly plate, the top of the drilling platform is provided with an assembly screw groove, the outer wall of the assembly plate is equipped with an assembly screw, and one end of the assembly screw extends into the interior of the assembly screw groove.

[0014] Preferably, the inner wall of the protective cover is inlaid with an adsorption magnetic block, and the outer wall of the adsorption magnetic block is provided with an iron adsorption mesh.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model collects the waste generated during drilling by installing a waste collection mechanism. Existing drilling tables cannot collect the waste generated during drilling, so this needs to be improved. First, there is a certain gap between the drilling table and the waste collection frame. Then, the waste collection frame is placed under the feeding trough. Then, the limiting plate is rotated to the bottom of the waste collection frame by the bearing. There are four sets of limiting plates, which are located at the four corners of the waste collection frame. At the same time, the spring is in a compressed state. When the limiting plate is under the waste collection frame and in contact with it, the locking block is manually released. The spring returns to its original position, causing the slide to move on the slide rod, which in turn causes the locking block to spring into the locking groove, thus limiting the position of the limiting plate and preventing the limiting plate from rotating at an angle. Then, the four sets of limiting plates lift the waste collection frame, so that the waste enters the waste collection frame through the feeding trough for collection.

[0017] 2. This utility model, by installing a protective mechanism, avoids the splashing of debris during drilling. Existing methods for drilling rails on a drilling platform result in debris splashing, necessitating improvement. Firstly, the protective cover is fixed to the top of the drilling platform using assembly screws in the assembly screw groove. Then, the rail is fed onto the base plate through the opening, and holes are drilled into the rail using the drilling groove. The size of the drilling groove is set according to the drilling shaft of the external drilling equipment, ensuring a match. The protective cover prevents debris splashing. Furthermore, because there is a gap between the drilling platform and the debris collection frame, the adsorption fan is activated. The adsorption fan operates at a low speed, not adsorbing the debris collected in the debris collection frame, but rather adsorbing dust. The adsorption fan then adsorbs the dust generated during drilling through the adsorption groove. The iron adsorption mesh is magnetically disassembled and installed for easy maintenance and cleaning later. Attached Figure Description

[0027] Please see Figure 1 and Figure 2A clamping assembly for drilling steel rails includes: a base plate 1, a clamping block 3, a drilling table 6, and a drilling groove 7. An electric slide rail 2 is installed on the top of the base plate 1, and the clamping block 3 is installed at the output end of the electric slide rail 2. A fixing plate 4 is installed on the top of the base plate 1, and a control box 5 is installed on the outer wall of the fixing plate 4. The drilling table 6 is located on the outer wall of the base plate 1, and the drilling groove 7 is provided on the top of the drilling table 6. The steel rail is placed on the base plate 1 and is located between the clamping block 3 and the fixing plate 4. Then, the electric slide rail 2 drives the clamping block 3 to move, and the clamping block 3 and the fixing plate 4 are used to clamp the steel rail. Then, the steel rail is drilled on the drilling table 6 by an external drilling device. The drilling groove 7 is concave and is used to provide a drilling space for the drilling shaft.

[0028] Please see Figure 2 , Figure 3 and Figure 4 The bottom of the drilling table 6 is equipped with a waste chip collection mechanism to collect the waste chips generated during drilling. The waste chip collection mechanism includes a waste chip collection frame 9 and a functional column 10. The inner wall of the drilling groove 7 is equipped with a feeding groove 8. The waste chip collection frame 9 is located at the bottom of the drilling table 6. The functional column 10 is installed at the bottom of the drilling table 6. A bearing 11 is embedded in the bottom of the functional column 10. A limit plate 12 is installed on the outer wall of the bearing 11. A rubber protective pad 13 is embedded in the outer wall of the limit plate 12. A locking groove 14 is provided at the top of the limit plate 12. A plate 15 is installed on the outer wall of the functional column 10. A slide rod 16 is installed at the bottom of the plate 15. A sliding plate 17 is installed around the outer wall of the slide rod 16. A spring 18 is installed at the bottom of the plate 15, and one end of the spring 18 extends to the outer wall of the sliding plate 17. A locking block 19 is installed on the outer wall of the sliding plate 17. Existing drilling tables 6 do not have this feature. The method for collecting waste generated during drilling needs to be improved. First, there is a certain gap between the drilling platform 6 and the waste collection frame 9. Then, the waste collection frame 9 is placed below the feeding trough 8. Then, the limiting plate 12 is rotated to the bottom of the waste collection frame 9 through the bearing 11. There are four sets of limiting plates 12, which are located at the four corners of the waste collection frame 9. At the same time, the spring 18 is under pressure. When the limiting plate 12 is below the waste collection frame 9 and fits, the locking block 19 is manually released. The spring 18 returns to its original position, causing the slide plate 17 to move on the slide rod 16. This causes the locking block 19 to spring into the locking groove 14, thus limiting the position of the limiting plate 12 and preventing the limiting plate 12 from rotating at an angle. Then, the four sets of limiting plates 12 lift the waste collection frame 9, and the waste enters the waste collection frame 9 through the feeding trough 8 for collection.

[0029] Please see Figure 1 and Figure 5The drilling table 6 has a protective mechanism on its top to prevent debris from flying during drilling. The protective mechanism includes a protective cover 20, an opening 21, and a drilling groove 22. The protective cover 20 is located on top of the drilling table 6. The outer wall of the protective cover 20 has the opening 21, which extends through the interior of the protective cover 20. The top of the protective cover 20 has a drilling groove 22. An assembly plate 23 is installed on the outer wall of the protective cover 20. The top of the drilling table 6 has an assembly screw groove 24. An assembly screw 25 is installed on the outer wall of the assembly plate 23, with one end of the assembly screw 25 extending into the assembly screw groove 24. An adsorption box 26 is installed on the top of the protective cover 20. Multiple adsorption fans 27 are installed on the inner wall of the adsorption box 26. The top of the adsorption box 26 has a ventilation groove 28. The top of the protective cover 20 has an adsorption groove 29. An adsorption magnet 30 is embedded in the inner wall of the protective cover 20. The outer wall of the adsorption magnet 30 has an iron... The existing method of drilling steel rails on the drilling table 6 results in the splashing of waste debris, which needs to be improved. First, the protective cover 20 is fixed to the assembly screw groove 24 by the assembly screw 25 and installed on the top of the drilling table 6. Then, the steel rail is fed onto the base plate 1 through the opening 21 and the steel rail is drilled through the drilling groove 22. The size of the drilling groove 22 is set according to the drilling shaft of the external drilling equipment. When matched, the protective cover 20 prevents the splashing of waste debris. Since there is a certain gap between the drilling table 6 and the waste debris collection frame 9, the adsorption fan 27 is started. The adsorption fan 27 operates on a weak airflow and does not adsorb the waste debris collected in the waste debris collection frame 9, but rather adsorbs the dust. The adsorption fan 27 adsorbs the dust generated during drilling through the adsorption groove 29. The iron adsorption net 31 is disassembled and installed magnetically for easy maintenance and cleaning in the future.

[0030] The working principle is as follows: the steel rail is placed on the base plate 1, positioned between the clamping block 3 and the fixing plate 4. Then, the electric slide rail 2 moves the clamping block 3, using the clamping block 3 and the fixing plate 4 to clamp the steel rail. Subsequently, an external drilling device drills holes in the steel rail on the drilling table 6. The drilling groove 7 is recessed, providing a drilling space for the drilling shaft. The existing drilling table 6 cannot collect the waste chips generated during drilling, so this needs to be improved. Firstly, there should be a certain gap between the drilling table 6 and the waste chip collection frame 9. The waste collection frame 9 is then placed below the feeding chute 8. The limiting plate 12 is then rotated to the underside of the waste collection frame 9 via the bearing 11. There are four sets of limiting plates 12, located at the four corners of the waste collection frame 9. Simultaneously, the spring 18 is under pressure. Once the limiting plate 12 is positioned below and in contact with the waste collection frame 9, the locking block 19 is manually released. The spring 18 returns to its original position, causing the slide plate 17 to move on the slide rod 16. This causes the locking block 19 to spring into the locking groove 14, thus limiting the position of the limiting plate 12 and preventing... When the limiting plate 12 rotates at an angle, the four sets of limiting plates 12 lift the waste collection frame 9, and the waste enters the waste collection frame 9 through the feeding chute 8 for collection. Currently, when drilling the rail on the drilling table 6, waste splashes occur, so this needs to be improved. First, the protective cover 20 is fixed to the assembly screw groove 24 by the assembly screw 25 and installed on the top of the drilling table 6. Then, the rail is fed onto the base plate 1 through the opening 21, and holes are drilled into the rail through the drilling groove 22. The size is set according to the drilling shaft of the external drilling equipment. If they match, the protective cover 20 will prevent the waste from splashing. Since there is a certain gap between the drilling table 6 and the waste collection box 9, the adsorption fan 27 will start. The adsorption fan 27 is a weak wind and will not adsorb the waste collected in the waste collection box 9, but will adsorb the dust. The adsorption fan 27 adsorbs the dust generated during drilling through the adsorption tank 29. The iron adsorption mesh 31 is disassembled and installed by magnetism for easy maintenance and cleaning later.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
