Description

Technical Field

[0001] This utility model relates to the field of straightening machine technology, and in particular to a handheld multi-core control cable core wire straightening machine. Background Technology

[0002] In current substation control cable wiring operations, the straightening of secondary cable cores generally relies on manual operation using pliers to straighten each core, which has problems such as low efficiency, poor consistency in multi-core processing, and high labor intensity.

[0003] Currently, most of the cable core straightening equipment on the market is large-scale fixed equipment. Although this type of equipment has a good straightening effect, it has the problems of being bulky and inconvenient to move, and is especially unsuitable for on-site construction or small-batch core straightening operations.

[0004] In addition, existing straightening equipment can often only be adapted to a single specification of core wire. When it is necessary to process core wires of different diameters, the entire straightening mechanism needs to be replaced, which is cumbersome and inflexible, and cannot meet the diverse needs of actual production and construction. Therefore, we have proposed a handheld multi-core control cable core wire straightening machine to solve the above problems. Utility Model Content

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a handheld multi-core control cable core straightening machine.

[0028] Reference Figure 1-5 A handheld multi-core control cable core straightening machine includes a housing 101. A handle 102 is installed on the top of the housing 101. Multiple rotating shafts 103 are rotatably mounted on the rear inner wall of the housing 101. A straightening roller 104 is fitted on the rotating shaft 103. A fixing sleeve 501 is fixedly fitted on the front and rear sides of the straightening roller 104. A fixing mechanism is provided between the fixing sleeve 501 and the corresponding rotating shaft 103. A frame plate 105 is provided inside the housing 101. Multiple rotating shafts 106 are rotatably mounted on the front and rear inner walls of the frame plate 105. An upward straightening roller 107 is fixedly fitted on the rotating shaft 106 and fitted with the corresponding downward straightening roller 104. A guide mechanism is provided between the frame plate 105 and the housing 101.

[0029] In this embodiment, the guiding mechanism includes a rectangular plate 201, a rectangular groove 202, a rectangular seat 203, and a fixed seat 204. Two rectangular plates 201 are fixedly installed on the top of the housing 101. A rectangular groove 202 is opened at the bottom of the rectangular plate 201. A rectangular seat 203 is slidably installed in the rectangular groove 202. Two fixed seats 204 are fixedly installed on the front and rear inner walls of the frame plate 105. The bottom of the rectangular seat 203 is fixedly installed on the corresponding fixed seat 204. Through the sliding cooperation of the rectangular seat 203 in the rectangular groove 202, a stable guide is provided for the up and down movement of the frame plate 105, ensuring that the upper straightening roller 107 is accurately aligned with the lower straightening roller 104, and ensuring the stability of the straightening process.

[0030] In this embodiment, each of the two rectangular plates 201 has a movable hole 301 on one side that is close to each other. The movable hole 301 is connected to the rectangular groove 202. The same movable plate 302 is slidably installed in the two movable holes 301. The movable plate 302 is fixedly connected to the rectangular base 203. The linkage design between the movable plate 302 and the rectangular base 203 realizes the stable transmission of a single driving force to the frame plate 105, avoids the frame plate 105 from shifting, and improves the accuracy of the spacing adjustment.

[0031] In this embodiment, a threaded hole 303 is provided on the top of the housing 101, and a drive screw 304 is installed in the threaded hole 303. The bottom end of the drive screw 304 is rotatably mounted on the movable plate 302, and a knob 305 is fixedly installed on the top end of the drive screw 304. A rotating groove is provided on the top of the movable plate 302, and an annular groove is provided on the inner wall of the rotating groove. An annular seat is fixedly installed on the drive screw 304, and the annular seat is rotatably connected to the annular groove. By utilizing the self-locking characteristics of the threaded transmission and the rotational cooperation of the annular structure, the height of the frame plate 105 can be accurately adjusted and stably positioned to meet the straightening spacing requirements of core wires of different specifications.

[0032] In this embodiment, the fixing mechanism includes a fixing groove 502, a bolt hole 503, and a fixing bolt 504. The rotating shaft 103 has multiple fixing grooves 502, and the inner wall of the fixing sleeve 501 has a bolt hole 503. The bolt hole 503 is threaded with a fixing bolt 504 that matches the fixing groove 502. The bolt is detachably connected to the groove, which enables the quick disassembly and replacement of the straight roller 104, reducing the difficulty of adapting different specifications of core wires.

[0033] In this embodiment, a control housing 401 is fixedly installed on the rear side of the housing 101. The rear end of the rotating shaft 103 extends into the control housing 401. Drive shafts 402 are rotatably installed on the inner walls of both sides of the control housing 401. A reduction motor 403 is fixedly installed on one side of the control housing 401. The reduction motor 403 is fixedly connected to the drive shaft 402. Three drive bevel gears 404 are fixedly installed on the drive shaft 402. A driven bevel gear 405 is fixedly installed at the rear end of the rotating shaft 103. The drive bevel gears 404 mesh with the corresponding driven bevel gears 405. The meshing transmission design of the bevel gear set realizes multi-axis synchronous rotation, ensures uniform core wire conveying speed, and improves the consistency of straightening effect.

[0034] In this embodiment, a controller is fixedly installed on the top of the housing 101, and the geared motor 403 is electrically connected to the controller. The controller and the geared motor 403 are electrically linked to realize convenient control of the equipment start and stop, and improve operational safety and work efficiency.

[0035] The working principle of this utility model is as follows: Before use, the operator can connect the drive screw 304 to the threaded hole 303 on the top of the housing 101 according to the diameter specification of the cable core wire to be straightened. When the knob 305 is turned, the drive screw 304 will move up and down. Its bottom end is rotatably connected to the annular groove on the moving plate 302 through the annular seat. Therefore, the rotation of the drive screw 304 will not drive the moving plate 302 to rotate, but will only drive the moving plate 302 to move up and down. The moving plate 302 is fixedly connected to the rectangular seat 203. The rectangular seat 203 slides in the rectangular groove 202 of the rectangular plate 201, thereby driving the frame plate 105 to move up and down. The rotating shaft 106 and the upper straightening roller 107 on the frame plate 105 also move up and down accordingly until the distance between the upper and lower straightening rollers 104 is suitable for the core wire specification. With the cooperation of the fixing bolt 504 and the fixing groove 502, it is possible to easily disassemble and replace the lower straightening roller 104, thereby making it easy to adapt to different core wire specifications.

[0036] After preparation, the operator holds the handle 102 on the top of the housing 101 and places one end of the multi-core control cable to be straightened between the upper straightening roller 107 and the lower straightening roller 104. The operator starts the geared motor 403 through the controller on the top of the housing 101. The geared motor 403 drives the drive shaft 402 inside the control housing 401 to rotate. The drive bevel gear 404 on the drive shaft 402 meshes with the driven bevel gear 405 at the rear end of the rotating shaft 103, thereby driving multiple rotating shafts 103 to rotate synchronously. The lower straightening roller 104 on the rotating shaft 103 also rotates accordingly.

[0037] Under the rotation of the lower straightening roller 104, the cable core is conveyed forward. At the same time, since the upper straightening roller 107 is adapted to the lower straightening roller 104, the core is squeezed by both, and the bent part is subjected to corrective force, gradually becoming straight, thus achieving the purpose of straightening the core.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
