Description

Technical Field

[0001] The utility model relates to the technical field of gear matching torsion arm pressing tooling, in particular to a gear matching torsion arm pressing tooling. Background Art

[0002] Gear-matching torque arm press-fitting tooling is widely used in the fields of machinery manufacturing, automobile manufacturing, aerospace, etc. that require high-precision assembly. This tooling is particularly important in applications where it is necessary to ensure accurate alignment of the teeth and stability of the assembly.

[0003] The gear-matching torque arm press-fitting tool is a special tool used to accurately press or assemble a torque arm with teeth or similar parts into another part such as a shaft, hole or other mechanical structure during the assembly process. It ensures the precise alignment of the teeth and the stability of the assembly during the press-fitting process. The gear-matching torque arm press-fitting tool is a tool used for assembling and disassembling automotive parts. It usually consists of a handle and one or more adjustable torque arms, and is used to press gears, bearings and other parts into or remove them from automotive engines, gearboxes and other parts;

[0004] However, the existing gear-matching torque arm press-fitting tool fixes the position of the pull rod by means of a nut. However, there is a risk of thread slippage in the nut. Once thread slippage occurs, the pull rod will rotate randomly during the pressurization process, which will affect the use of the gear-matching torque arm press-fitting tool. Based on this, a gear-matching torque arm press-fitting tool is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a toothed torque arm press-fitting tool, which solves the technical problem that due to the risk of thread slippage of the nut, once thread slippage occurs, the pull rod will rotate randomly during the pressurization process, thus affecting the use of the toothed torque arm press-fitting tool.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A gear-matching torque arm press-fitting tool comprises a torsion bar, one end of which is connected to a pull rod, a torque arm is arranged on the torsion bar, a torque arm sinking platform is arranged on the torsion arm, a torque arm press-fitting sleeve is sleeved on the torsion bar, the torque arm press-fitting sleeve is close to the torque arm sinking platform, a hydraulic jack is arranged on the torsion bar, and a nut is threadedly connected to the torsion bar.

[0008] As a further solution of the utility model: a limiting structure is arranged on the nut, the limiting structure includes a limiting rod, two limiting rods are arranged, the two limiting rods are fixedly mounted on the torsion bar, a mounting ring is fixedly mounted on the side of the nut away from the hydraulic jack, and a rectangular groove is opened on the limiting structure.

[0009] As a further solution of the utility model: the number of the rectangular grooves is two, and the two limiting rods are respectively obtained to pass through the two rectangular grooves.

[0010] As a further solution of the utility model: a mounting groove is provided in each of the two rectangular grooves, and a plurality of the mounting grooves are provided, and balls are rotatably installed in each of the plurality of mounting grooves.

[0011] As a further solution of the utility model: the side of the limiting rod close to the ball contacts the outer surface of the ball.

[0012] As a further solution of the utility model: the torsion rod and the pull rod are threadedly connected, and the torsion arm sinker and the torsion arm are matched.

[0013] Beneficial effects of the utility model:

[0014] (1) The utility model provides accurate positioning and guidance for the entire press-fitting process by first screwing the pull rod into the thread at the end of the torsion bar and screwing it to the maximum position during the press-fitting process of the torsion arm. Due to the threaded connection between the pull rod and the torsion bar, it ensures that the torsion arm can be accurately aligned with the torsion bar during the press-fitting process, avoiding misalignment or tilting. Then, a torque arm press-fitting sleeve is used to fix the torque arm to the torsion bar for the convenience of subsequent pressure transmission. When the top surface of the torque arm press-fitting sleeve is in close contact with the torque arm sinker, the pull rod becomes the main medium for transmitting pressure, and the pressure of the hydraulic jack is gradually increased to 20-MPa. The pull rod evenly transmits this pressure to the torque arm, so that the torque arm can be smoothly pressed into the torsion bar. At the same time, the tail of the pull rod is tightened with a nut to prevent the pull rod from moving during the pressurization process, thereby realizing the press-fitting operation of the geared torque arm.

[0015] (2) The utility model fixes the mounting ring to one side of the nut after tightening the tail of the pull rod with a nut, and at the same time allows the limit rod to pass through the rectangular groove. When the limit rod rotates left or right, the position of the pull rod is fixed by the cooperation of the limit rod and the rectangular groove, thereby preventing the pull rod from rotating during use. At the same time, the ball bearings arranged in the rectangular groove do not restrict the forward and backward movement of the pull rod, thereby further ensuring the normal displacement requirements of the pull rod and preventing the pull rod from rotating at will during the pressurization process.

[0026] The torsion bar 1 and the pull rod 7 are threadedly connected, and the torsion arm sink 2 and the torsion arm 3 are adapted to each other, which is conducive to the installation and use of the torsion bar 1 and the pull rod 7;

[0027] Embodiment 2

[0028] Based on Example 1, please refer to Figure 1-Figure 2As shown, a limiting structure 8 is provided on the nut 6, and the limiting structure 8 includes a limiting rod 81, and the position of the pull rod 7 is fixed by the matching of the limiting rod 81 and the rectangular groove 83. There are two limiting rods 81, and the two limiting rods 81 are fixedly installed on the torsion bar 1. A mounting ring 82 is fixedly installed on the side of the nut 6 away from the hydraulic jack 5, and the limiting rod 81 is limited by the mounting ring 82, thereby limiting the pull rod 7. A rectangular groove 83 is opened on the limiting structure 8, and there are two rectangular grooves 83. The two limiting rods 8 1 respectively obtain two rectangular grooves 83 that penetrate through, which is conducive to the installation of the ball 85 and the limiting rod 81. The two rectangular grooves 83 are provided with a mounting groove 84, and a plurality of mounting grooves 84 are provided. The plurality of mounting grooves 84 are rotatably installed with the ball 85. The ball 85 provided in the rectangular grooves 83 does not restrict the forward and backward movement of the pull rod 7, further ensuring the normal displacement requirement of the pull rod 7 while preventing the pull rod 7 from rotating at will. The side of the limiting rod 81 close to the ball 85 contacts the outer surface of the ball 85;

[0029] The working principle of the utility model is as follows: in the process of press-fitting the torsion arm 3, the pull rod 7 is first screwed into the thread at the end of the torsion bar 1 and screwed to the maximum position, which provides accurate positioning and guidance for the entire press-fitting process. Due to the threaded connection between the pull rod 7 and the torsion bar 1, it ensures that the torsion arm 3 can be accurately aligned with the torsion bar 1 during the press-fitting process, avoiding misalignment or tilting; then the torsion arm press-fitting sleeve 4 is used to fix the torsion arm 3 to the torsion bar 1 for the convenience of later pressure transmission; when the top surface of the torsion arm press-fitting sleeve 4 is in close contact with the torsion arm sinking platform 2, the pull rod 7 becomes the main medium for transmitting pressure, and the pressure of the hydraulic jack 5 is gradually increased to 20-30MPa. The pull rod 7 evenly transmits this pressure to the torsion arm 3, so that the torsion arm 3 can be smoothly pressed into the torsion bar 1, and at the same time, the tail of the pull rod 7 is tightened with a nut 6 to prevent the pull rod 7 from moving during the pressurization process;

[0030] After tightening the tail of the pull rod 7 with the nut 6, the mounting ring 82 is fixed to one side of the nut 6, and the limit rod 81 passes through the rectangular groove 83. When the limit rod 81 rotates left and right, the position of the pull rod 7 is fixed by the cooperation of the limit rod 81 and the rectangular groove 83 to prevent the pull rod 7 from rotating during use. At the same time, the ball 85 arranged in the rectangular groove 83 does not restrict the forward and backward movement of the pull rod 7, which further ensures the normal displacement requirement of the pull rod 7 and prevents the pull rod 7 from rotating at will during the pressurization process.
