Description

Technical Field

[0001] This utility model relates to the field of cable tray manufacturing technology, specifically a punching device for cable tray manufacturing. Background Technology

[0002] Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or laid on various building and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. The quality of the cable tray supports should meet current relevant technical standards. When laying cable trays horizontally, the optimal route should be determined based on the building layout plan, the installation of air conditioning and electrical pipelines, ease of maintenance, and the density of cable routes. All parts must be galvanized.

[0003] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type. They consist of two side plates and support arms connecting the side plates. During the production of cable trays, a drilling device is needed to drill holes in their surface. However, the most common drilling methods currently use a motor to rotate the drill bit, which then drills holes in the cable tray surface. But since the diameter of the drill bit is fixed, it can only be used for opening holes of a single size. If the opening size needs to be adjusted temporarily, the drill bit needs to be replaced and recalibrated. The adjustment process is cumbersome and prone to causing holes that are too large or too small due to dimensional errors.

[0004] Therefore, we propose a drilling device for cable tray production to solve the above problems. Utility Model Content

This solves the problem mentioned in the background art, which describes cable trays as having various structures such as trough type, tray type, ladder type, and mesh type, consisting of two side plates and connecting arms. During cable tray production, a drilling device is needed to drill holes in the surface. However, current common drilling methods often utilize a motor to rotate the drill bit, which then drills holes in the cable tray surface. Since the drill bit's diameter is fixed, it is only suitable for single-size openings. If a temporary adjustment of the opening size is needed, the drill bit must be replaced and recalibrated, making the adjustment process cumbersome and prone to causing holes that are too large or too small due to dimensional errors.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an embodiment of this utility model proposes a drilling device for cable tray production, including a base 1, a support 2 fixed to one side of the top of the base 1, a moving mechanism 3 slidably connected to one side of the top of the support 2, and a first motor 4 fixed to one side of the top of the moving mechanism 3. The first motor 4 is electrically connected to an external motor through a wire, and the first motor 4 is controlled by an electrical signal issued by a controller. The first motor 4 is an NFP-5840-555-EN series motor that can rotate in both directions and has a self-locking structure.

[0031] The output end of the first motor 4 is connected to a connecting seat 5, and the bottom of the connecting seat 5 is connected to a rotating seat 6. A rotating wheel 7 is rotatably connected to the inner side of the connecting seat 5, and a first threaded rod 8 is fixedly connected to the bottom of the rotating wheel 7. A threaded tube 9 is sleeved on the outer side of the bottom of the first threaded rod 8, and a lifting seat 10 is fixedly connected to the bottom of the threaded tube 9. An internal thread is formed on the inner side of the threaded tube 9, and the threaded tube 9 forms a threaded connection with the first threaded rod 8 through this internal thread. A pressing block 11 is fixedly provided on the outer ring surface of the top of the lifting seat 10. The pressing block 11 is generally convex in shape, and its outer diameter matches the inner diameter of the fitting groove 19. The pressing blocks 11 are equidistantly distributed along the center point of the lifting seat 10. The rotating seat 6... An auxiliary structure is provided on the inner side of the rotating seat 6. The auxiliary structure includes a cavity 12, a through groove 13, a groove 14 and a slide 15. The cavity 12 is opened in the inner cavity of the rotating seat 6, and one side of the cavity 12 is connected to the through groove 13. The through groove 13 is distributed equidistantly along the center point of the rotating seat 6. The other side of the through groove 13 is connected to the groove 14, and one side of the groove 14 is connected to the slide 15. An adjustable blade 16 is slidably connected to one side of the bottom of the rotating seat 6, and a slider 17 is fixed on one side of the top of the adjustable blade 16. A push block 18 is fixed on one end of the top of the adjustable blade 16, and an adaptation groove 19 is opened on the inner side of the push block 18. The size of the adaptation groove 19 is adapted to the size of the extrusion block 11, and the adaptation groove 19 is opened in an inclined shape.

[0032] In use, the moving mechanism 3 pushes the rotating seat 6 to the contact position with the cable tray surface. Then, the first motor 4 operates, causing the connecting seat 5 connected to its output end to rotate. The rotation of the connecting seat 5 realizes the rotation of the rotating seat 6, thereby realizing the rotation of the adjustable blade 16, which facilitates subsequent drilling of the cable tray. When it is necessary to adjust the position of the adjustable blade 16, the rotating wheel 7 is turned. At this time, the rotating wheel 7 drives the first threaded rod 8 connected to its bottom center to rotate. The rotation of the first threaded rod 8 drives the threaded tube 9 sleeved on its outer surface to move longitudinally. At this time, the longitudinal movement of the threaded tube 9 pushes the lifting seat 10 fixedly connected to its bottom. The longitudinal movement of the lifting seat 10 drives the extrusion block 11 to move synchronously. Since the extrusion block 11 is slidably engaged inside the adapter groove 19, as the extrusion block 11 moves longitudinally, the extrusion block 11 pushes the push block 18. At this time, the push block 18 moves laterally along the through groove 13. The adjustable blade 16 moves laterally as the pusher block 18 pushes it. As the adjustable blade 16 moves, the sliders 17 symmetrically arranged on both sides slide along the groove 15, thereby improving the stability of the adjustable blade 16 during lateral movement. As the multiple adjustable blades 16 expand outward, the drilling diameter can be adjusted, facilitating subsequent drilling of different sizes. During adjustment, the maximum stroke distance of the adjustable blade 16 is two-thirds of the slider 17 size, preventing the strength of the entire drilling structure from being affected by the excessive distance the adjustable blade 16 moves out. It is worth noting that when the extrusion block 11 engages with the adapter groove 19, the inclined groove on the side wall of the extrusion block 11 engages with the symmetrically arranged inclined protrusions on the inner side wall of the adapter groove 19, limiting and guiding the movement. At the same time, the length of the connection between the front end of the extrusion block 11 and the lifting seat 10 is sufficient to allow the extrusion block 11 to reach the designated position in the adapter groove 19.

[0033] like Figure 8 As shown, in some embodiments, a positioning hole 20 is provided on the outer periphery of the top of the rotating wheel 7. The positioning holes 20 are equidistantly distributed along the center point of the rotating wheel 7. A return spring 21 is connected to one side of the bottom of the connecting seat 5, and a positioning rod 22 is connected to the bottom of the return spring 21. The two ends of the return spring 21 are respectively connected to one end of the positioning rod 22 and the inner cavity of the connecting seat 5. A detachable end cap is provided on the surface of the connecting seat 5 for subsequent replacement of the return spring 21. An auxiliary sliding plate 23 is sleeved on the outer ring surface of the positioning rod 22, and a toggle block 24 is fixed on the surface of the auxiliary sliding plate 23.

[0034] When in use, when the positioning rod 22 and the positioning hole 20 are on the same horizontal line, the longitudinal force applied to the lever 24 is released. As the lever 24 moves longitudinally, the auxiliary slide plate 23 will drive the positioning rod 22 to move, which in turn causes the positioning rod 22 to deform and generate a reverse force. Therefore, when the force applied to the lever 24 disappears, the reverse force generated by the deformation of the return spring 21 will push the positioning rod 22 in the opposite direction, thereby inputting one end of the positioning rod 22 into the inner side of the positioning hole 20 to achieve the positioning of the rotating wheel 7. It is worth noting that since the return spring 21 is vertically set, the centrifugal force generated when the connecting seat 5 rotates will not affect the normal longitudinal extension and contraction of the return spring 21.

[0035] like Figure 1 and Figure 3 As shown, in some embodiments, a worktable 25 is distributed on the side of the top of the base 1 away from the support 2, and a boss 26 is fixed on one side of the top of the worktable 25. The boss 26 is symmetrically arranged on both sides of the top of the worktable 25. A second motor 27 is fixed on the side wall of the boss 26, and the output end of the second motor 27 is connected to a second threaded rod 28. The second motor 27 is electrically connected to an external motor through a wire, and the second motor 27 is controlled by the electrical signal issued by the controller. The second motor 27 is an NFP-5840-555-EN series motor that can rotate in both directions and has a self-locking structure. A threaded sleeve 29 is fitted on the outer surface of the second threaded rod 28, and a clamping seat 30 is fixed on the top of the threaded sleeve 29. A threaded hole with a diameter that matches the outer diameter of the second threaded rod 28 is opened on the inner side of the threaded sleeve 29. Multiple rubber anti-slip strips are evenly distributed on the side wall of the clamping seat 30.

[0036] In use, the cable tray to be drilled is placed on the upper surface of the boss 26. At this time, the second motor 27 works and the second threaded rod 28 connected to its output end rotates accordingly. Since the second threaded rod 28 is threadedly connected to the threaded sleeve 29 through the external thread on its surface, the rotation of the second threaded rod 28 can realize the lateral movement of the threaded sleeve 29. In turn, the lateral movement of the threaded sleeve 29 can realize the lateral movement of the clamping seat 30, which facilitates the subsequent clamping and limiting treatment of the cable tray by using the clamping seats 30 that move in opposite directions on both sides.

[0037] like Figure 5 As shown, in some embodiments, an internal thread groove is provided on the inner side of the top end of the threaded tube 9, and the threaded tube 9 forms a threaded connection with the first threaded rod 8 through the internal thread groove.

[0038] In use, since the threaded tube 9 is connected to the first threaded rod 8 by the internal thread groove, the rotation of the first threaded rod 8 can facilitate the movement of the threaded tube 9.

[0039] In summary, during use, the cable tray to be drilled is placed on the boss 26 and clamped and limited by the symmetrically arranged clamping seats 30 on both sides. After clamping, the moving mechanism 3 pushes the rotating seat 6 to the position of contact with the cable tray surface. Then, the first motor 4 drives the rotating seat 6 to rotate through the connecting seat 5. The rotation of the rotating seat 6 realizes the rotation of the adjustable blade 16, which facilitates the subsequent drilling of the cable tray. When it is necessary to adjust the position of the adjustable blade 16, the rotating wheel 7 is turned. At this time, the rotating wheel 7 drives the first threaded rod 8 connected to the middle of its bottom end to rotate. Then, the rotation of the first threaded rod 8 drives the threaded tube 9 sleeved on its outer surface to move longitudinally. At this time, the longitudinal movement of the threaded tube 9 will push the lifting seat 10 fixedly connected to its bottom. The longitudinal movement of the lifting seat 10 drives the extrusion block 11 to move synchronously. Since the extrusion block 11 is slidably engaged with the inner side of the adapter groove 19, the extrusion block 11 will push the push block 18 as the extrusion block 11 moves longitudinally. At this time, the push block 18 moves laterally along the through groove 13. Then, as the push block 18 pushes, the adjustable blade 16 also moves laterally. As the adjustable blade 16 moves, the sliders 17 symmetrically arranged on both sides slide along the slide groove 15, thereby improving the stability of the adjustable blade 16 during the lateral movement. As the multiple adjustable blades 16 expand outward, the drilling diameter can be adjusted, which is convenient for subsequent drilling of different sizes. After adjustment, the positioning rod 22 and the positioning hole 20 are on the same horizontal line. At this time, the longitudinal force applied to the push block 24 is released. Since the longitudinal movement of the push block 24 will cause the auxiliary slide plate 23 to drive the positioning rod 22 to move, the positioning rod 22 will drive the return spring 21 to deform and generate a reverse force. Therefore, when the force applied to the push block 24 disappears, the reverse force generated by the deformation of the return spring 21 will push the positioning rod 22 in the opposite direction, thereby inputting one end of the positioning rod 22 into the inner side of the positioning hole 20 to achieve the positioning of the rotating wheel 7.
