Description

Technical Field

[0001] The present application relates to the technical field of steel mesh production, and in particular to a steel bar positioning device. Background Art

[0002] Steel mesh is a mesh in which longitudinal and transverse steel bars are arranged at a certain interval and at right angles to each other, and all intersections are welded or tied together.

[0003] The staff arranges the steel bars at a certain interval so that they are evenly spaced in the horizontal and vertical directions, and welds or ties the intersections. The staff generally locates the steel bars by measuring the distance one by one or using preset clamps, and then welds or ties them.

[0004] Regarding the above-mentioned related technologies, manual distance measurement by staff is tedious and prone to errors, while the distance between adjacent steel bars on the preset fixture is fixed. Both methods have low processing efficiency and low degree of automation. Summary of the Invention

[0005] In order to improve processing efficiency and automation, the present application provides a steel bar positioning device.

[0006] The present application provides a steel bar positioning device that adopts the following technical solution:

[0007] The top end face of said sliding arm is fixedly provided with a toothed plate, and the toothed plate is pivotally connected to the toothed plate by a bolt, and the bolt has a round shank to contact with the toothed plate, and the toothed plate is connected with the toothed plate in a vertical direction thereof.

[0008] By adopting the above technical solution, the staff first drives the second drive assembly to slide the sliding block upward, separating the abutment teeth from the positioning rack. Then, the staff drives the first drive assembly, which causes the support plate to slide along the length of the positioning rack, thereby changing the relative position of the support plate on the frame and the spacing between two adjacent support plates. The staff then places the steel bars into the positioning slots on the support plates. This method allows for quick and easy adjustment of the support plate position, thereby improving processing efficiency and automation.

[0009] Preferably, the support plate is also provided with a rotating block, the length direction of the rotating block is parallel to the length direction of the positioning rack, the middle part of the length direction of the rotating block is rotatably connected to the support plate, the rotating block rotates around the length direction of the steel bar, and an abutment block is fixed on the sliding block, and the side of the rotating block close to the abutment block in the length direction is pressed against the lower side of the abutment block, and the second driving assembly is arranged on the side of the rotating block in the length direction away from the abutment block, for driving the rotating block on this side to rotate downward.

[0010] By employing the above-mentioned technical solution, the staff member notifies the second drive assembly, thereby driving the end of the rotating block facing away from the abutment block to rotate downward, and the end of the rotating block near the abutment block to rotate upward, thereby driving the abutment block to drive the sliding block to slide upward, separating the abutment teeth from the lower positioning rack. After the first drive assembly drives the support plate to the preset position, the second drive assembly leaves the rotating block, and the sliding block slides downward under the action of gravity, causing the abutment teeth to embed in the positioning rack, thereby relatively fixing the support plate and the frame. This method facilitates the fixing or separation of the support plate and the frame, helping to improve the automation level of the entire device.

[0011] Preferably, a positioning bolt is provided on the support plate, the axial direction of the positioning bolt is parallel to the length direction of the steel bar, the positioning bolt passes through the support plate and the middle part of the rotating block along its own axial direction, and a positioning nut is also provided on the end of the positioning bolt.

[0012] By adopting the above technical solution, the staff can adjust the resistance of the rotating block during rotation by adjusting the locking degree between the positioning bolt and the positioning nut.

[0013] Preferably, the second driving assembly includes a driving cylinder, and a driving cylinder is also provided on the frame. A clamping column is fixed to the end of the driving cylinder piston rod, and a clamping hole is provided on the support plate. The clamping hole is provided on the side of the rotating block away from the abutment block in the length direction of the rotating block, and the clamping hole is located on the upper side of the rotating block. The driving cylinder drives the clamping column and the clamping hole to be plugged into and matched, and the end of the clamping column away from the driving cylinder is tapered.

[0014] By adopting the above technical solution, when the abutment tooth is embedded in the positioning rack, the abutment block is pressed against the side of the rotating block close to the abutment block. The rotating block tilts downward along its own length from the side away from the abutment block to the side close to the abutment block. The upper side of the rotating block is higher than the lower side of the clamping hole. When the staff drives the clamping column to move toward the side close to the support plate, the tapered end of the clamping column is inserted into the clamping hole, and the clamping column continues to move. The lower side of the clamping column abuts against the upper side of the rotating block, causing the side of the rotating block away from the abutment block to rotate downward, and the side of the rotating block close to the abutment block to rotate upward, thereby pushing the abutment block to push the sliding block to slide upward, causing the abutment tooth to separate from the positioning rack.

[0015] Preferably, the first drive component includes a positioning plate, the drive cylinder body is fixedly connected to the positioning plate, and the support plates are symmetrically arranged in two groups on both sides of the length direction of the steel bar. The first drive component is respectively provided with at least one on the side of the two groups of support plates facing away from each other, and the second drive component is correspondingly provided with one on the two positioning plates.

[0016] By adopting this technical solution, the first drive assembly drives the second drive assembly to slide along the length of the positioning rack, and the clamping posts and clamping holes are plugged in and engaged. The number of first drive groups can be increased or decreased according to actual conditions. After the first drive assembly slides, the drive cylinder and clamping posts align with the support plate. This approach helps reduce the cost of the entire device.

[0017] Preferably, the first driving component includes a positioning plate, which slides on the frame along the length direction of the positioning rack. A driving motor is provided on the positioning plate, and the housing of the driving motor is fixed on the positioning plate. A driving gear is also coaxially fixed on the output shaft of the driving motor. A fixed rack is also provided on the frame, and the length direction of the fixed rack is parallel to the length direction of the positioning rack. The driving gear is engaged with the fixed rack.

[0018] By adopting the above technical solution, the staff controls the driving motor to engage the driving gear with the fixed rack, thereby driving the positioning plate to slide on the frame along the length direction of the positioning rack. In this way, it is convenient to accurately control the relative position of the positioning plate on the frame, thereby accurately controlling the relative position of the support plate on the frame.

[0019] Preferably, two support plates are arranged at intervals along their own thickness direction, the rotating block is arranged between the two support plates, any of the support plates is provided with a guide plate, and the guide plates are respectively fixedly connected to the two support plates, and one guide plate is provided on each side of the positioning groove in the width direction.

[0020] By adopting the above technical solution, the guide plate helps workers to place the steel bars into the positioning groove, thereby helping to improve processing efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The two symmetrically arranged support plates and the positioning grooves on the support plates facilitate the positioning of the steel bars by the workers.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiment of the present application discloses a steel bar positioning device.

[0030] See also Figure 1-Figure 2The steel bar positioning device includes a frame 1, which includes two aluminum profiles 11 arranged in a horizontally symmetrical manner, and the length direction of the aluminum profile 11 is perpendicular to the length direction of the steel bar 100. A slide rail 14 is fixed on the upper side of the aluminum profile 11, and the length direction of the slide rail 14 is parallel to the length direction of the aluminum profile 11. A support plate 21 is provided on any aluminum profile 11, and the support plate 21 is vertically arranged. A positioning groove 22 is provided on the support plate 21, and the positioning groove 22 passes through the support plate 21 along the length direction of the steel bar 100, and the upper side of the positioning groove 22 is open. Two support plates 21 are arranged at intervals along the length direction of the steel bar 100 to form a support assembly 2, and a slider 26 is fixed to the lower end of the support assembly 2, and the slider 26 slides and cooperates with the slide rail 14 along the length direction of the slide rail 14. The support assembly 2 is detachably connected to the aluminum profile 11 through the slide rail 14 and the slider 26. The support plate 21 is also provided with a guide plate 25 on its upper side. One guide plate 25 is provided on each side of the positioning slot 22 in the width direction. The sides of the two guide plates 25 that are closer to each other smoothly transition into the upper side walls of the positioning slot 22. The sides of the positioning slot 22 in the width direction converge from top to bottom toward the closer side. In this way, the positioning slot 22 can accommodate rebars 100 of varying diameters, allowing the rebars 100 to be relatively flat in the radial direction, making it easier for workers to weld or tie the rebars 100.

[0031] The support assembly 2 also includes sliding plates. Each support plate 21 is provided with a sliding groove 23, located on one side of the width of the support plate 21 and extending through the thickness of the support plate 21. A sliding block 3 is positioned within the sliding groove 23, positioned between the two support plates 21. Abutment teeth 31 are provided at the bottom of the sliding plate. A positioning rack 12 is fixed to the aluminum profile 11, its length running parallel to the length of the aluminum profile 11. The abutment teeth 31 engage with the positioning rack 12 vertically.

[0032] A rotating block 5 is provided on the side of each support plate 21 facing away from the sliding block 3 in the width direction. The thickness direction of the rotating block 5 is parallel to the thickness direction of the support plate 21. The rotating block 5 is arranged between the two support plates 21. A positioning bolt 6 is also provided on the support plate 21. The axial direction of the positioning bolt 6 is parallel to the thickness direction of the support plate 21. The positioning bolt 6 passes through the two support plates 21 and the rotating block 5 along its own axial direction. The positioning bolt 6 is located in the middle of the length direction of the rotating block 5. A positioning nut 61 is also sleeved on the end of the positioning bolt 6. The end faces of the positioning nut 61 and the head of the positioning bolt 6 are respectively pressed against the sides of the two support plates 21 facing away from each other.

[0033] An abutment block 4 is also fixed to the side of the sliding block 3 closest to the rotating plate. The lower side of the abutment block 4 abuts against the upper side of the longitudinal side of the rotating block 5. The support plate 21 also has a latching hole 24, which penetrates the support plate 21 along its thickness. When the abutment teeth 31 are inserted into the positioning rack 12, the abutment block 4 abuts against the longitudinal side of the rotating block 5. The upper side of the rotating block 5, facing away from the abutment block 4, is higher than the bottom end of the latching hole 24.

[0034] A first drive assembly 7 is also provided on any aluminum profile 11. The first drive assembly 7 includes a positioning plate 71. The positioning plate 71 is detachably connected to the aluminum profile 11 via a linear guide and a linear slider. The length direction of the linear guide is parallel to the length direction of the aluminum profile 11, and the linear slider slides and cooperates with the linear guide along its own length direction. A drive motor 72 is provided on the positioning plate 71. The housing of the drive motor 72 is fixedly connected to the positioning plate 71, and a drive gear 73 is coaxially fixed to the output shaft of the drive motor 72. A fixed rack 13 is also fixed on the aluminum profile 11 on this side. The length direction of the fixed rack 13 is parallel to the length direction of the aluminum profile 11, and the drive gear 73 is meshed with the fixed rack 13. In actual work, the staff controls the drive motor 72, thereby controlling the drive gear 73 to mesh with the fixed rack 13, thereby driving the positioning plate 71 to slide and cooperate with the aluminum profile 11 along the length direction of the aluminum profile 11.

[0035] The positioning plate 71 is also provided with a second drive assembly 8, which includes a drive cylinder 81. The cylinder body of the drive cylinder 81 is fixedly connected to the positioning plate 71, and the piston rod of the drive cylinder 81 is extended and retracted in a direction parallel to the thickness direction of the support plate 21. A clamping post 82 is fixed to the end of the piston rod of the drive cylinder 81. The length direction of the clamping post 82 is parallel to the thickness direction of the support plate 21, and the end of the clamping post 82 facing away from the drive cylinder 81 is tapered. The clamping post 82 is engaged with the clamping hole 24 along its own axis. The staff controls the extension and retraction of the drive cylinder 81 so that the clamping post 82 is inserted into the clamping hole 24. The clamping post 82 presses down on the rotating block 5, causing the side of the rotating block 5 facing away from the abutment block 4 to rotate downward, and the side of the rotating block 5 facing the abutment block 4 to rotate upward, thereby pushing the abutment block 4 to slide upward, driving the sliding block 3 to slide upward, and separating the abutment tooth 31 from the fixed rack 13.

[0036] There are multiple support assemblies 2 on either side spaced apart along the length direction of the aluminum profile 11 on that side. At least one pair of first drive assemblies 7 are symmetrically arranged on the two aluminum profiles 11, and at least one second drive assembly 8 is respectively arranged on the two first drive assemblies 7. After the staff controls the clamping column 82 to engage with the clamping hole 24, they control the first drive assembly 7 to drive the corresponding support assembly 2 to slide along the length direction of the aluminum profile 11. When it is necessary to move another support assembly 2, the staff first drives the clamping column 82 to separate from the clamping hole 24, drives the first drive assembly 7 to drive the positioning plate 71 to slide along the length direction of the aluminum profile 11, so that the clamping column 82 on the positioning plate 71 corresponds to the clamping hole 24 on the other support plate 21 that needs to be moved, and then drives the piston rod of the driving cylinder 81 to extend, so that the clamping column 82 is engaged with the clamping hole 24, and then drives the first drive assembly 7 to change the relative position of this support plate 21 on the frame 1.

[0037] The implementation principle of a steel bar positioning device according to an embodiment of the present application is as follows: before the processing operation, the staff controls the drive motor 72 to drive the drive gear 73 to rotate, the drive gear 73 engages with the fixed rack 13, and drives the positioning plate 71 to slide on the aluminum profile 11. When the clamping column 82 corresponds to the clamping hole 24 on the first support assembly 2 that needs to be moved, the drive motor 72 is stopped, and the staff controls the piston rod of the drive cylinder 81 to extend so that the clamping column 82 is inserted into the corresponding clamping hole 24. The clamping column 82 presses down the side of the rotating block 5 that is away from the abutment block 4 in the length direction, so that the side of the rotating block 5 that is close to the abutment block 4 in the length direction rotates upward, pushing the abutment block 4, thereby pushing the sliding block 3 to slide upward, so that the abutment tooth 31 is separated from the positioning rack 12. The staff then controls the drive motor 72 to rotate, and the clamping column 82 drives the support plate 21, thereby driving the support assembly 2 to slide along the length direction of the aluminum profile 11. When the support assembly 2 moves to the preset position, the drive motor 72 is stopped and the piston rod of the drive cylinder 81 is controlled to retract, thereby disengaging the clamping post 82 from the clamping hole 24. The sliding block 3 rotates downward under the action of gravity, and the abutment teeth 31 are inserted into the positioning rack 12, thereby fixing the support assembly 2 relative to the aluminum profile 11. The staff then controls the drive motor 72 to drive the positioning plate 71 to move to the corresponding position of the next support assembly 2 to be moved.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
