Description

Technical Field

[0001] The invention relates to the technical field of metal pre-embedded sleeve positioning and cutting, in particular to a metal pre-embedded sleeve positioning and cutting device. Background Art

[0002] The embedded sleeve is a metal component pre-installed in the concrete structure, and its function is usually to provide a fixing point for other components installed subsequently. The variable diameter embedded sleeve is a special steel bar connector, which is mainly used to connect two steel bars of different diameters together. In the existing technology for producing and processing variable diameter embedded sleeves, a smaller opening that passes through both ends is generally drilled on the metal cylinder with a milling cutter, and then two reamers of different sizes are used to expand the holes to specific lengths at both ends until the metal cylinder is cut and expanded into the required variable diameter cylinder. The interior of the variable diameter cylinder is composed of two cylindrical grooves of different diameters and different lengths that are interconnected, so as to facilitate the subsequent tapping of the two cylindrical grooves of different diameters by two taps of corresponding sizes, thereby finally processing the variable diameter cylinder into the required variable diameter embedded sleeve, wherein the length of the small diameter cylindrical groove in the variable diameter cylinder is usually smaller than the length of the large diameter cylindrical groove.

[0003] However, the traditional method of cutting and processing the variable-diameter embedded sleeve has the following problems: in the prior art, when cutting and processing the metal cylinder used as the raw material for the variable-diameter embedded sleeve, the metal cylinder is usually first fed and transported to a position aligned with the axis of the hole-opening milling cutter and clamped and fixed, so that the hole-opening milling cutter makes a hole in the inside of the metal cylinder, and then the metal cylinder is transported to a position aligned with the axis of a reaming reamer of one size and clamped and fixed, so that the reaming reamer of that size drills and expands one end of the hole inside the metal cylinder, and finally the metal cylinder is adjusted in direction and transported to a position aligned with the axis of the reaming reamer of another size and clamped and fixed, so that the reaming reamer of that size drills and expands the other end of the hole inside the metal cylinder , thereby cutting and processing two variable diameter cylindrical grooves that meet the requirements of the variable diameter embedded sleeve inside the metal cylinder. However, the above-mentioned cutting and processing method not only requires the metal cylinder to be reversed and transported and positioned multiple times, resulting in the overall processing steps of the variable diameter embedded sleeve being relatively cumbersome and the processing efficiency still needs to be further improved, and the two ends of the metal cylinder are cut and expanded in one direction in turn. Since the one-way cutting and expanding the hole will cause uneven stress distribution on the metal cylinder, and the overall wall thickness of the metal cylinder will be greatly reduced during the cutting and expanding process, the weak points on the metal cylinder will produce a certain degree of deformation during the cutting process, thereby affecting the accuracy of the overall cutting and expanding of the metal cylinder and the overall quality of the finished product of the variable diameter embedded sleeve.

[0034] See also Figure 1 、 Figure 2 and Figure 3 The unloading component 46 includes a U-shaped positioning frame 461 fixedly arranged on the side of the U-shaped connecting plate 441 close to the support platform 42 and with its opening facing the guide frame 431, and a supporting plate 463 fixedly arranged on the side of the supporting frame 443 away from the guide frame 431 and located below the U-shaped positioning frame 461, wherein a unloading trough 462 is opened in the U-shaped positioning frame 461 and passes through from top to bottom.

[0035] like Figure 3 As shown, when the variable diameter cylinder 2 drilled and cut on the clamping mechanism 5 is to be removed, the support bracket 443 is first driven to move the maximum distance by the pneumatic cylinder 2, so that the support bracket 443 supports the variable diameter cylinder 2 and the arc-shaped limit plate 454 is aligned with the variable diameter cylinder 2, and then the clamping plate 453 and the arc-shaped limit plate 454 are driven downward by the pneumatic cylinder 3 452 to clamp and position the variable diameter cylinder 2 on the support bracket 443, and the clamping mechanism 5 releases the clamping fixation of the variable diameter cylinder 2, and finally the support bracket 443 and the variable diameter cylinder 2 are driven to move and reset by the pneumatic cylinder 2 442, so that the support bracket 443 is docked with the guide frame 431 and the U-shaped positioning frame 461, the variable diameter cylinder 2 is aligned with the placement groove 432 and the discharge groove 462, and the support plate 463 closes the lower end of the discharge groove 462 (as shown in FIG. Figure 3 As shown in the middle part), the clamping plate 453 and the arc-shaped limiting plate 454 are moved upward to release the clamping and positioning of the variable diameter cylinder 2, thereby removing the variable diameter cylinder 2 from the clamping mechanism 5.

[0036] When the variable diameter cylinder 2 on the support bracket 443 is to be unloaded and the metal cylinder 1 to be processed placed in the guide rack 431 is to be loaded, the U-shaped push plate 434 is first driven to move by the pneumatic cylinder 1 433, so that the U-shaped push plate 434 drives all the metal cylinders 1 in the placement groove 432 and the variable diameter cylinder 2 on the support bracket 443 to move synchronously until the variable diameter cylinder 2 is completely moved into the unloading groove 462, and at this time, the metal cylinder 1 closest to the loading assembly 44 is just moved onto the support bracket 443 and aligned with the arc-shaped limit plate 454, wherein the guide plate 455 can be moved around the variable diameter cylinder The cylinder 2 and the metal cylinder 1 are provided with a limit when they move, and then the metal cylinder 1 on the support bracket 443 is clamped and positioned by the clamping plate 453 and the arc-shaped limit plate 454, and then the support bracket 443 and the metal cylinder 1 are driven by the pneumatic cylinder 2 442 to move the maximum distance and align with the clamping mechanism 5, so that the clamping mechanism 5 clamps and fixes the metal cylinder 1, thereby completing the loading of the metal cylinder 1, and when the supporting plate 463 moves synchronously with the supporting bracket 443 and is completely separated from the lower end of the discharge chute 462, the variable diameter cylinder 2 in the discharge chute 462 falls accordingly to complete the discharge (such as Figure 3As shown on the right side), the baffle plate 444 that moves synchronously with the support bracket 443 can limit the metal cylinder 1 in the placement groove 432 to prevent the metal cylinder 1 from falling off from the end of the placement groove 432.

[0037] When the metal cylinder 1 is loaded, the clamping plate 453 and the arc-shaped limit plate 454 move upward to release the clamping of the metal cylinder 1, and the support bracket 443 is driven to move and reset a certain distance by the pneumatic cylinder 2 442, so that the support bracket 443 will not hinder the subsequent drilling and cutting processing and flip adjustment of the metal cylinder 1, and at the same time, the blocking plate 444 can continue to limit the metal cylinder 1 in the placement groove 432 until the metal cylinder 1 is drilled and cut into the variable diameter cylinder 2 that needs to be unloaded. The above-mentioned operation method can realize stable fixed-point loading and unloading of the metal cylinder 1, thereby not only ensuring the stability of the subsequent clamping mechanism 5 in clamping and positioning the metal cylinder 1 and the accuracy of the drilling and cutting mechanism 6 in positioning and drilling the metal cylinder 1, but also in the process of loading the metal cylinder 1, the variable diameter cylinder 2 that is expanded and formed can be unloaded simultaneously, thereby improving the continuity and efficiency between the loading and unloading of the metal cylinder 1 as a whole, thereby improving the overall processing efficiency of the variable diameter embedded sleeve.

[0038] See also Figure 1 The clamping mechanism 5 includes two adjustment platforms 51 symmetrically fixed along the width direction of the connecting frame 41 on the lower L-shaped connecting plate 31 close to the feeding mechanism 4, and a clamping component 52 and an adjustment component 53 jointly arranged on the two adjustment platforms 51.

[0039] See also Figure 5 The clamping assembly 52 includes a rotating shaft 521 rotatably set on the corresponding adjusting platform 51, and a U-shaped connecting plate 522 is fixedly set on the opposite end of the symmetrical rotating shaft 521, and a fixing plate 523 is fixedly set on the opposite side of the symmetrical U-shaped connecting plate 522, and a pneumatic cylinder 4 524 is fixedly set on the opposite side of the symmetrical fixing plate 523. The telescopic end of the pneumatic cylinder 4 524 is fixedly provided with a U-shaped clamping claw 525 that moves along the width direction of the L-shaped connecting plate 31, and the four corners of the U-shaped clamping claw 525 close to the side of the pneumatic cylinder 4 524 are fixedly provided with a guide rod 526 that is slidably connected to the corresponding fixing plate 523, and the U-shaped clamping claw 525 is symmetrically provided with positioning holes 527 that pass through it from top to bottom along its length direction.

[0040] See also Figure 1 and Figure 5The adjustment assembly 53 includes gears 531 fixedly arranged on opposite ends of the symmetrical rotating shaft 521, and a pneumatic cylinder 532 is fixedly arranged on the side of the symmetrical adjustment platform 51 away from the connecting frame 41 through a support. The telescopic end of the pneumatic cylinder 532 is fixedly provided with a rack 533 that moves along the length direction of the adjustment platform 51 and is meshed with the corresponding gear 531.

[0041] When the metal cylinder 1 positioned and transported by the support bracket 443 is to be clamped, the pneumatic cylinder 4 524 synchronously drives the symmetrical U-shaped claws 525 to move relative to each other until the metal cylinder 1 is clamped and fixed; when the vertically clamped metal cylinder 1 is to be flipped and adjusted by ninety degrees, the symmetrical pneumatic cylinder 5 32 drives the corresponding rack 533 to move synchronously, and the rack 533 then drives the corresponding rotating shaft 521 to rotate stably by ninety degrees through the meshing transmission with the corresponding gear 531, and the rotating shaft 521 then drives the corresponding U-shaped claw 525 and the metal cylinder 1 clamped and fixed by the U-shaped claw 525 to rotate synchronously by ninety degrees through the U-shaped connecting plate 2 522, thereby flipping the vertical metal cylinder 1 to a horizontal state. The above-mentioned operation method can realize fast and stable clamping of the metal cylinder 1, and can realize ninety-degree stable rotation adjustment of the clamped metal cylinder 1, thereby facilitating the rapid and stable positioning and drilling of the metal cylinder 1 in cooperation with the drilling and cutting mechanism 6.

[0042] See also Figure 1 and Figure 4 The drilling and cutting mechanism 6 includes a feeding assembly 61 arranged on the corresponding fixed platform 32 and a drilling and cutting assembly 62 arranged on the corresponding feeding assembly 61.

[0043] See also Figure 4 and Figure 6 The feeding assembly 61 includes a pneumatic cylinder 611 fixedly set on the corresponding fixed platform 32 on the side away from the adjustment platform 51. The telescopic end of the pneumatic cylinder 611 is fixedly provided with a feeding platform 612. The four corners of the feeding platform 612 close to the corresponding fixed platform 32 are fixedly provided with guide rods 613 slidably connected to the corresponding fixed platform 32. The two feeding platforms 612 on the upper and lower sides can move up and down, and the feeding platform 612 on the remaining side moves along the length direction of the L-shaped connecting plate 31.

[0044] See also Figures 4 to 6The drilling and cutting assembly 62 includes a driving assembly 621 fixedly arranged on the corresponding feed table 612 near the side of the adjustment table 51, and each driving assembly 621 is fixedly provided with a positioning plate 622, and the four corners of the positioning plate 622 are elastically slidably provided with elastic plug rods 623 that are plugged into the corresponding positioning holes 527, wherein a reaming reamer 1 625 is installed on the driving end of the upper driving assembly 621, and a reaming reamer 2 626 is installed on the driving end of the lower driving assembly 621, and a hole milling cutter 624 is installed on the driving end of the remaining side driving assembly 621, and the reaming diameter of the reaming reamer 1 625 is larger than the reaming diameter of the reaming reamer 2 626.

[0045] When drilling and cutting a hole in the metal cylinder 1 clamped and fixed by the U-shaped clamp 525, the rack 533 is first engaged with the corresponding gear 531 to rotate the U-shaped clamp 525 by ninety degrees. At the same time, the metal cylinder 1 clamped and fixed by the U-shaped clamp 525 is also synchronously adjusted from a vertical state to a horizontal state. At this time, the metal cylinder 1 in the horizontal state is just aligned with the axis of the hole milling cutter 624. Then, the corresponding pneumatic cylinder 611 drives the drive assembly 621 and the hole milling cutter 624 on the corresponding feed table 612 to move, and the corresponding positioning plate 622 is synchronously adjusted accordingly. The elastic insertion rod 623 is driven to move and plug into the positioning hole 527 on the corresponding U-shaped clamp 525 for positioning, thereby ensuring the stability and accuracy of the hole-cutting milling cutter 624 in drilling and cutting the hole in the metal cylinder 1. Then, the moving hole-cutting milling cutter 624 is driven by the corresponding driving assembly 621 to continuously drill and cut the hole in the metal cylinder 1 until a through hole is opened in the metal cylinder 1. Since the diameter of the through hole is small and the wall thickness of the metal cylinder 1 is thick, the uneven stress distribution caused by the unidirectional drilling and cutting has little effect on the metal cylinder 1 and is less likely to cause deformation of the metal cylinder 1.

[0046] When the through hole drilled in the metal cylinder 1 is to be expanded, the metal cylinder 1 in the horizontal state is first adjusted to a vertical state. At this time, the metal cylinder 1 in the vertical state is just aligned with the axis of the upper reamer 625 and the lower reamer 626. Then, the upper and lower pneumatic cylinders 611 drive the upper and lower symmetrical drive assemblies 621 to move synchronously relative to each other, and the upper and lower symmetrical elastic inserts 623 are then synchronously inserted into the corresponding positioning holes 527 to ensure that the reamer 625 and the reamer 626 are aligned. The stability and accuracy of drilling and cutting the metal cylinder 1 are improved, and the elastic plug rod 623 is elastically slidably connected to the corresponding positioning plate 622, which can ensure that the ends of the upper and lower symmetrical elastic plug rods 623 do not hinder the feeding of the corresponding driving assembly 621 when they conflict with each other. Then, the corresponding driving assembly 621 drives the reaming reamer 1 625 and the reaming reamer 2 626 to drill and reame the upper and lower ends of the metal cylinder 1 synchronously. Since the reaming diameter of the reaming reamer 2 626 is smaller than that of the reaming reamer 1 625, the reaming diameter of the reaming reamer 2 626 is smaller than that of the reaming reamer 1 625. The hole diameter is large, and the length of the small-diameter cylindrical groove in the variable-diameter cylinder 2 is usually smaller than the length of the large-diameter cylindrical groove. Therefore, after the reaming reamer 2 626 is fed upward for the required distance, it is first driven downward by the corresponding pneumatic cylinder 611 to reset. This not only avoids the collision between the reaming reamer 1 625 and the reaming reamer 2 626, but also enables the debris generated by the drilling and cutting process in the metal cylinder 1 to be stably discharged downward from the cylindrical groove at the lower end. The reaming reamer 1 625 needs to continue to feed downward and drill until the metal cylinder is 1 is cut and expanded into the required variable diameter cylinder 2. The above operation method can not only realize the rapid and stable connection between the drilling and cutting hole processing and the drilling and expanding hole processing of the metal cylinder 1, but also realize the relative feeding of the two sizes of expanding reamers to simultaneously perform drilling and expanding holes on the two ends of the metal cylinder 1, thereby greatly simplifying the overall transportation and adjustment operation of the metal cylinder 1, improving the overall drilling and cutting processing efficiency of the variable diameter embedded sleeve, and solving the problem of deformation of the metal cylinder 1 due to uneven stress distribution during the drilling and expanding hole process.
