Description

Technical Field

[0001] This utility model relates to the field of anti-torsion arm technology for tightening machines, and in particular to a high-strength alloy device for anti-torsion arm of tightening machines. Background Technology

[0002] The reverse gear nut is required during transmission assembly. Currently, the domestic reverse gear nut tightening process typically involves using a pneumatic wrench connected to an extension rod, tightening with a universal socket, and then manually tightening with a pre-set wrench. When the shaft and hole clearance is appropriate, a steel rod is also needed to hold the gear in place. The manual tightening process uses a pneumatic wrench and pliers for pre-tightening, and a pre-set wrench for final tightening. This process is time-consuming, resulting in low assembly efficiency, high labor intensity, and poor torque consistency in the products. Furthermore, there is a risk of the tightening device hitting the gear inside the gearbox during the tightening process.

[0003] Publication (Announcement) No.: CN218225450U discloses a device for the tightening reaction force of a reverse gear nut assembly, including a suspension device, an anti-torsion arm connecting device, an angle adjustment connecting device, and a rotary adapter tightening machine. The anti-torsion arm adopts a multi-segment telescopic carbon arm structure, which is lightweight, easy to move, and reduces labor intensity. The tightening machine is installed on the rotary adapter, which is equipped with bearings and expansion bushings to ensure flexible rotation of the tightening machine. The built-in sleeve in the Beijing-Tianjin-Hebei region contains a sponge with marking oil, which marks the bolts during the bolt tightening process, eliminating the need for an additional bolt marking process.

[0004] Existing torque arms cannot be adjusted in length, and the angle adjustment is also very limited, resulting in a small range of applications. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing torque arms, such as the inability to adjust length and limited angle adjustment, and their narrow applicability. This invention proposes a high-strength alloy anti-torsion arm device for tightening machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The high-strength alloy anti-torsion arm device for the tightening machine includes:

[0008] The height adjustment mechanism is used to control the torque arm to adjust its height.

[0009] L-shaped alloy parts are connected to the height adjustment mechanism;

[0010] Angle adjustment mechanism, fixedly connected to L-shaped alloy component;

[0011] A support arm is fixedly connected to an angle adjustment mechanism. The support arm has a telescopic groove, and a telescopic arm is slidably installed in the telescopic groove. A telescopic mechanism is provided in the telescopic groove, and the telescopic arm is connected to the telescopic mechanism.

[0012] A wire twisting motor is connected to a telescopic arm, and a screw tool is mounted on the output shaft of the wire twisting motor.

[0013] Preferably, the height adjustment mechanism includes a slide rail, a threaded rod rotatably mounted inside the slide rail, a height adjustment block threadedly connected to the outer side of the threaded rod, the height adjustment block being fixedly mounted to an L-shaped alloy part, a servo motor being mounted at the top of the threaded rod, and the output shaft of the servo motor being fixedly mounted at the top of the slide rail; the servo motor drives the threaded rod to rotate, the threaded rod drives the height adjustment block to move downward, and the height adjustment block drives the L-shaped alloy part to move downward.

[0014] Preferably, the height adjustment block has notches on both sides, and notch strips are fixedly installed on the inner walls of both sides of the slide rail. The two notch strips are slidably connected to the inner walls of the two notches to ensure that the height adjustment block moves vertically.

[0015] Preferably, the angle adjustment mechanism includes a fixed box connected to an L-shaped alloy part. An angle shaft is rotatably mounted inside the fixed box via a bearing. The angle shaft is fixedly mounted to a support arm. A motor is installed inside the fixed box. A worm gear is mounted on the output shaft of the motor. A worm wheel is sleeved on the outer side of the angle shaft. The worm gear meshes with the worm wheel. The motor drives the angle shaft to rotate through the cooperation of the worm gear and the worm wheel. The angle shaft drives the support arm to rotate. The support arm and the telescopic arm drive the screw tool to adjust the angle.

[0016] Preferably, the telescopic mechanism includes a lead screw rotatably mounted in a telescopic groove. A lead screw groove is formed on the telescopic arm, and the lead screw is threadedly connected to the lead screw groove. A stepper motor is mounted on the top of the support arm, and a first bevel gear is mounted on the output shaft of the stepper motor.

[0017] Preferably, a rectangular frame is fixedly installed on the outer side of the telescopic arm, the torsion motor is located inside the rectangular frame, and two bolts are threadedly connected to the outer side of the rectangular frame to fix the torsion motor.

[0018] The beneficial effects of the high-strength alloy anti-torsion arm device for the tightening machine described in this utility model are as follows:

[0019] This solution places the torsion motor inside a rectangular frame and fixes it with two bolts. The servo motor drives the threaded rod to rotate, which in turn drives the height adjustment block to move downward. The height adjustment block then drives the L-shaped alloy part to move downward. The L-shaped alloy part, through the angle adjustment mechanism, support arm, and telescopic arm, drives the rectangular frame, torsion motor, and screw tool to move downward. The torsion motor and screw tool perform the torsion. The motor drives the angle shaft to rotate through the cooperation of the worm and worm wheel. The angle shaft drives the support arm to rotate, and the support arm and telescopic arm drive the screw tool to adjust the angle.

[0020] In this solution, a stepper motor drives the first bevel gear to rotate, and the first bevel gear drives the lead screw to rotate through the second bevel gear. The lead screw and the lead groove cooperate to drive the telescopic arm to move. The telescopic arm drives the screw tool to adjust the extension and retraction length, thus expanding the scope of application.

[0021] This invention allows for adjustment of the angle, height, and length range of the twisted wire position, which can meet usage requirements and expand the scope of application. Attached Figure Description
