Description

Technical Field

[0001] The utility model relates to the technical field of cable production equipment, in particular to a motor base capable of tensioning a toothed synchronous belt. Background Art

[0002] The microcomputer-controlled ￠630 cantilever single-strand twister is a stranding machine widely applicable to various types of soft or hard conductors. The payout system consists of four active back-twist payout frames placed in different locations. Each active back-twist payout frame is welded from square steel and A3 steel plate. The payout and back-twist motors are driven by inverters to control the payout and rotation speeds of the payout reels. The takeup frame then twists the strands together, twisting multiple single conductors into a single strand to meet the wire processing requirements.

[0003] In order to make the mechanical transmission structure of the wire reel pay-off and rotation of each active back-twist pay-off frame more compact, the pay-off motor and the back-twist motor need to be installed on the square steel. Not only how to install the pay-off motor and the back-twist motor on the active back-twist pay-off frame, but also how to tension the toothed synchronous belt installed between the toothed synchronous belt pulley on the outstretched shaft of the pay-off motor and the back-twist motor and the toothed synchronous belt pulley on the transmission shaft at the same time, this is also a technical problem that has troubled people in this field in the cable industry.

[0023] Example 1

[0024] like Figure 1-5 The present embodiment provides a motor base capable of tensioning a toothed synchronous belt, comprising a pay-off frame square steel 1, wherein a channel steel 3 is provided on the front side of the pay-off frame square steel 1 through a hexagon socket head screw a4, the channel steel 3 opening facing forward, and two parallel strip-shaped through holes 31 are provided on the waist of the channel steel 3 along its length direction, the hexagon socket head screw a4 being arranged in the strip-shaped through holes 31, a horizontal plate 2 is horizontally provided on the upper side of the pay-off frame square steel 1, the horizontal plate 2 is connected to the top of the channel steel 3 by electric welding, and a vertical plate 8 is vertically provided on the rear side of the pay-off frame square steel 1, and the vertical plate 8 is connected to the rear end of the horizontal plate 2 by electric welding.

[0025] A push block 5 is welded inside the channel steel 3. The push block 5 is in the shape of a rectangular parallelepiped. A fixing block 6 is welded on the front side of the pay-off frame square steel 1. The fixing block 6 is in the shape of a rectangular parallelepiped and has a threaded hole. A hexagon socket head screw B7 is installed in the threaded hole. The end of the hexagon socket head screw B7 is pressed against the push block 5. By rotating the hexagon socket head screw B7 to tighten or loosen the push block 5, the toothed synchronous belt installed on the toothed synchronous wheel of the extension shaft of the pay-off motor or the back-twist motor and the toothed synchronous wheel of the transmission shaft is tightened or loosened.

[0026] Two rows of screw holes 11 corresponding to the positions of the strip-shaped through holes 31 are set on the front side of the wire rack square steel 1. The hexagon socket head screws a4 are threadedly set in the screw holes 11, and the strip-shaped through holes 31 and the outer threads and rods of the hexagon socket head screws a4 are clearance-fitted.

[0027] There is a gap between the vertical plate 8 and the pay-off frame square steel 1. Two screw holes are machined on the vertical plate 8. The internal threads of the screw holes are provided with hexagon socket head screws C9. The ends of the hexagon socket head screws C9 are tightened against the pay-off frame square steel 1. By tightening the hexagon socket head screws C9, the motor base can be tightened against the pay-off frame square steel 1.

[0028] Four mounting holes 21 are provided on the transverse plate 2. The pay-off motor or the back-twist motor can be fastened to the transverse plate 2 by passing the four mounting holes 21 with a hexagonal bolt and a washer nut assembly.

[0029] The width of the horizontal plate 2 is greater than the width of the vertical plate 8, which makes it easy to use special tools to fasten the pay-off motor or the back-twist motor to the horizontal plate 2 of the motor base or remove it from the horizontal plate 2 of the motor base. The bottom of the vertical plate 8 and the bottom of the channel steel 3 do not exceed the bottom of the pay-off frame square steel 1, which makes it easy to place the motor base on a horizontal surface to install or remove the pay-off motor or the back-twist motor. The top of the channel steel 3 and the top of the vertical plate 8 both exceed the top of the pay-off frame square steel 1, and a gap is left between the horizontal plate 2 and the pay-off frame square steel 1. When the motor base is installed on the pay-off frame square steel 1, the gap between the horizontal plate 2 and the pay-off frame square steel 1 makes it easy to tighten the motor base to the pay-off frame square steel 1 by rotating the hexagon socket head screw b7.

[0030] The method of using the utility model is to first vertically weld the fixing block 6 to the specified position of the pay-off frame square steel 1, then assemble the other parts processed on the motor base in sequence, and then use special tools to fasten each pay-off motor or back-twist motor to the horizontal plate 2 of the motor base in sequence.

[0031] Taking advantage of the production gap, the pay-off motors or back-twist motor assemblies to be installed on the motor base are hoisted to the installation position on the pay-off frame square steel 1. By adjusting the hexagon socket head screw b7 and tightening the hexagon socket head screws a4 and the hexagon socket head screw c9, the pay-off motor or back-twist motor assembly can be installed in place.

[0032] Then, according to the production process requirements and equipment operating procedures, after all preparations are completed, production can be started.
