Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a reinforcing steel bar threading processing technical field, especially in an engineering reinforcing steel bar threading machine. BACKGROUND
[0002] The reinforcing steel bar threading machine is a mechanical setting for thread processing of the end of reinforcing steel bars in construction engineering, facilitating the connection between reinforcing steel bars.
[0003] In the working process of the reinforcing steel bar threading machine, the reinforcing steel bar is clamped through the clamping device, and then the end of the reinforcing steel bar is covered by the reinforcing steel bar threading machine for threading processing.
[0004] Although the clamping device is equipped with a two-way screw rod centering clamp at present, the reinforcing steel bar can be clamped and centered, so that the reinforcing steel bar can be aligned with the reinforcing steel bar threading machine, but the length of the reinforcing steel bar to be threaded is relatively long, and the length of the clamp is limited, so that when the reinforcing steel bar is divided by the clamp, the end of the reinforcing steel bar away from the reinforcing steel bar threading machine is relatively heavy, which causes the end of the reinforcing steel bar away from the reinforcing steel bar threading machine to incline downward in the clamping process, and the threaded hole processed at this time cannot be matched for use, thereby reducing the stability of the reinforcing steel bar threading processing. UTILITY MODEL CONTENTS

Detailed Implementation
[0033] 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.
[0034] This utility model provides, for example Figures 1-4 The diagram shows a rebar threading machine for engineering applications, comprising a workbench 101, a clamping mechanism, a support component, and an adjusting mechanism. The workbench 101 has a threading machine body 102 at its top. The clamping mechanism is located at the top of the workbench 101 and is used to position the rebar to be threaded. The support component includes a support plate 201, which is located on one side of the clamping mechanism and is used to support the rebar to be clamped. The adjusting mechanism is located below the support plate 201 and is used to change the height of the support plate 201. The rebar is placed on the top of the support plate 201 and passes through the clamping mechanism. The support plate 201 supports the rebar, and then the clamping mechanism clamps it. This design prevents tilting when the rebar is too long, thus improving the stability of the rebar threading process. Furthermore, the adjusting mechanism allows for height adjustment of the support plate 201, enabling it to support rebars of different sizes, thereby improving its applicability.
[0035] The clamping mechanism includes a fixed base 301, clamping blocks 302, and a moving mechanism. The bottom end of the fixed base 301 is fixedly connected to the top end of the worktable 101. The clamping blocks 302 are symmetrically slidably disposed on the top end of the fixed base 301. V-grooves 303 are provided on opposite sides of the two clamping blocks 302. The moving mechanism is disposed at the bottom end of the clamping blocks 302. Through the setting of the V-grooves 303, when the two clamping blocks 302 move relative to each other, the steel bars between the two clamping blocks 302 can be centered and clamped, ensuring that the steel bars can be aligned with the threading machine body 102, and further improving the stability of the steel bar threading process.
[0036] The moving mechanism includes a slider 402 and a bidirectional lead screw 403. The top end of the slider 402 is fixedly connected to the bottom end of the clamping block 302. The top end of the fixed base 301 is provided with a groove 401. The outer wall of the slider 402 is slidably connected to the inner wall of the groove 401. The bidirectional lead screw 403 is rotatably connected to the inner wall of the groove 401. A first threaded hole 404 is provided on one side of the slider 402. The outer wall of the bidirectional lead screw 403 is threadedly connected to the inner wall of the first threaded hole 404. A rotating mechanism is provided at one end of the bidirectional lead screw 403. The outer wall of the bidirectional lead screw 403 is provided with symmetrical threads, which allows the bidirectional lead screw 403 to rotate and mesh with the threads on the inner wall of the first threaded hole 404. This allows the two sliders 402 to move relative to or away from each other in the groove 401, thereby driving the clamping block 302 to move, thus improving the convenience of the clamping mechanism.
[0037] The rotating mechanism includes a rotating plate 501 and a rotating rod 502. One end of the bidirectional lead screw 403 passes through the inner wall of the slide groove 401 and is fixedly connected to one side of the rotating plate 501. The rotating rod 502 is fixedly connected to the outer wall of the rotating plate 501 in a ring array. The arrangement of the rotating plate 501 and the rotating rod 502 facilitates the rotation of the bidirectional lead screw 403 on one side of the fixed seat 301, thereby improving the convenience of the moving mechanism.
[0038] The adjustment mechanism includes a fixed plate 601 and a threaded rod 602. The fixed plate 601 is fixedly connected to the front of the fixed base 301. The top end of the threaded rod 602 is rotatably connected to the bottom end of the support plate 201. The top end of the fixed plate 601 is provided with a second threaded hole 603. The outer wall of the threaded rod 602 is threadedly connected to the inner wall of the second threaded hole 603. By rotating the threaded rod 602, and with the thread engagement between the outer wall of the threaded rod 602 and the inner wall of the second threaded hole 603, the rotation of the threaded rod 602 can drive the support plate 201 to rise and fall. Thus, the height of the support plate 201 can be adjusted according to the size of the reinforcing bar, so that the clamping mechanism can stably clamp the reinforcing bar.
[0039] The support plate 201 has multiple limiting guide rods 701 fixedly connected to its bottom end, and the fixed plate 601 has multiple limiting guide holes 702 at its top end. The outer wall of the limiting guide rod 701 is movably inserted into the inner wall of the limiting guide hole 702. Through the mutual limiting and guiding of the limiting guide hole 702 and the limiting guide rod 701, the support plate 201 will not rotate when the threaded rod 602 rotates and drives the support plate 201 to rise and fall. The support plate 201 can only move straight up and down, thereby improving the stability of the adjustment of the support plate 201.
[0040] The fixing plate 601 is fixedly connected to a fixing piece 801 on one side. The fixing piece 801 is provided with a scale line 802 on one side. The top of the support plate 201 is aligned with the scale on the scale line 802, which is the radius of the steel bar to be clamped, thereby improving the accuracy of the adjustment mechanism. When the top of the support plate 201 is aligned with the zero mark of the scale line 802, the top of the support plate 201 is aligned with the middle of the V-groove 303.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
