Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a torque reaction arm tooling. Background Technology

[0002] Currently, the battery packaging assembly section of the production line uses a combination of manual and automated equipment. Many manual and automated workstations use clutch wrenches and automatic torque guns (i.e., electric torque wrenches) to tighten bolts, with torque ranging from 3N to 90N. When employees use the tightening gun to tighten high torque, they are subjected to the force of the high torque feedback, which can easily cause them to lose their grip or even get injured, resulting in decreased product quality and endangering employee safety. Therefore, it is crucial to equip high-torque tightening positions with reaction arms, which can improve product tightening quality and protect employee safety.

[0003] However, existing torque guns use lifting rings or wireless transmission, which can cause a large reaction force to workers, especially for torques of 90N, and cannot effectively eliminate the reaction force. Therefore, it is necessary to develop a reaction arm specifically for product configuration. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a torque reaction arm tooling.

[0005] This utility model proposes a torque reaction arm tooling for assisting an electric torque wrench in installing bolts. It includes a mounting frame, on which a mounting rod is vertically mounted. The length of the mounting rod is adjustable, and an elastic block is mounted at the end of the mounting rod. When the electric torque wrench is working, the elastic block is in a compressed state and contacts and abuts against the end of the electric torque wrench.

[0006] The elastic block can be made of rubber, as is available in the prior art. By adjusting the length of the mounting rod, the elastic block is kept in a compressed state during the operation of the electric torque wrench. When the electric torque wrench operates at high torque, the elastic block can disperse some of the torque reaction force, reducing the force borne by the operator.

[0007] As a further optimization of this utility model, the end of the mounting rod is provided with an abutment plate, and the elastic block is mounted on the abutment plate by an elastic element. During the installation of the bolt, the elastic element is in a compressed state.

[0008] The elastic element can be a spring as in existing technology, further increasing the vibration reduction effect and reducing the reaction force on the operator during high torque operation of the electric torque wrench.

[0009] To facilitate the tightening of bolts in the vertical direction by the operator, when the electric torque wrench tightens the bolt with its axis in the vertical direction, the elastic element can deform in the vertical direction, and the bottom of the elastic block abuts against the top of the electric torque wrench.

[0010] To facilitate the tightening of bolts in a horizontal position, when the electric torque wrench tightens the bolt with its axis in the horizontal direction, the elastic element can undergo elastic deformation in the horizontal direction, and the bottom of the elastic block abuts against the side of the electric torque wrench.

[0011] As a further optimization of this utility model, the bottom of the mounting bracket has a support plate, the bottom of the support plate has an elastic pad, and the support plate is placed on a processing table or the ground.

[0012] This further increases the overall stability of the mounting bracket.

[0013] As a further optimization of this utility model, an elastic pad is installed at the bottom of the support plate, and the support plate is placed on a processing table or the ground. The elastic pad can be made of rubber, which is common in the prior art.

[0014] This further enhances the vibration damping effect of the mounting bracket and extends its service life.

[0015] As a further optimization of this utility model, a sliding mechanism is installed on the mounting bracket, and the mounting rod is installed on the sliding mechanism. The sliding mechanism is used to drive the mounting rod to move in the horizontal plane.

[0016] This allows for the tightening of bolts at different locations without moving the mounting bracket.

[0017] As a further optimization of this utility model, the sliding mechanism includes a first slide rail and a first slider slidably mounted on the first slide rail, the mounting rod is mounted on the first slider, and a first fixing member is detachably mounted between the first slider and the first slide rail.

[0018] This facilitates auxiliary vibration reduction when tightening bolts at different positions without moving the mounting bracket.

[0019] Preferably, based on the above technical solution, the mounting bracket is equipped with two sets of parallel second slide rails, each set of second slide rails is slidably mounted with a second slider, a connecting rod is provided between the two sets of second sliders, the first slide rail is mounted on the connecting rod, a second fixing member is provided between each set of second sliders and each set of second slide rails, and the second slide rail is perpendicular to the first slide rail.

[0020] This allows the elastic block to move in the X, Y, and Z axes, thus facilitating auxiliary vibration reduction when tightening bolts at different positions without moving the mounting bracket.

[0021] In this utility model, the proposed torque reaction arm tooling adjusts the length of the mounting rod to ensure that the elastic block is in a compressed state during the operation of the electric torque wrench. When the electric torque wrench operates at high torque, the elastic block can disperse part of the torque reaction force, reducing the force borne by the operator.

[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] Example 1

[0029] like Figure 1The diagram shows a torque reaction arm tooling used to assist in the installation of bolts on an electric torque wrench. It includes a mounting frame 1, on which a mounting rod 2 is vertically mounted. The length of the mounting rod 2 is adjustable. Specifically, the mounting rod 2 includes an upper connecting rod 20 and a lower telescopic rod 21. The upper connecting rod 20 is mounted on the mounting frame 1 by bolts or welding. The bottom of the upper connecting rod 20 has a threaded hole. The lower telescopic rod 21 has external threads on its exterior, and the external threads match the threaded hole. The total length of the mounting rod 2 is adjusted by rotating the lower telescopic rod 21. An elastic block 3 is installed at the end of the mounting rod 2. When the electric torque wrench is working, the elastic block 3 is in a compressed state and contacts and abuts against the end of the electric torque wrench.

[0030] The elastic block 3 can be made of rubber, as is available in the prior art. By adjusting the length of the mounting rod 2, the elastic block 3 can be adjusted to be in a compressed state during the operation of the electric torque wrench. When the electric torque wrench is operating at high torque, the operator holds the electric torque wrench to tighten the bolt. The elastic block 3 can disperse part of the torque reaction force, reducing the reaction force of the electric torque wrench on the operator.

[0031] Preferably, the end of the mounting rod 2 is provided with an abutment plate 4, which can be installed at the end of the mounting rod 2 by welding. The elastic block 3 is installed on the abutment plate 4 by an elastic element 5. In order to facilitate the operator to tighten the bolts in the vertical direction, when the electric torque wrench tightens the bolts with the axis in the vertical direction, the elastic element 5 can deform in the vertical direction, and the bottom of the elastic block 3 abuts against the top of the electric torque wrench. During the bolt installation process, the elastic element 5 is in a compressed state.

[0032] The elastic element 5 can be a spring as in the prior art, which further increases the vibration reduction effect and reduces the reaction force on the operator during the high torque operation of the electric torque wrench.

[0033] Prior to this, the bottom of the mounting bracket 1 has a support plate 6, which is placed on a processing table or the ground to further increase the overall stability of the mounting bracket 1.

[0034] An elastic pad 7 is installed at the bottom of the support plate 6. The support plate 6 is placed on a processing table or the ground. The elastic pad 7 can be made of rubber, which is available in the prior art. This further enhances the vibration damping effect of the mounting bracket 1 and increases the service life of the mounting bracket 1.

[0035] Example 2

[0036] like Figure 2As shown, in order to facilitate the tightening of bolts in a horizontal position by the operator, the difference between this embodiment and the above embodiment is that when the electric torque wrench tightens the bolt with the axis in the horizontal direction, the elastic element 5 can undergo elastic deformation in the horizontal direction, and the bottom of the elastic block 3 abuts against the side of the electric torque wrench.

[0037] Example 3

[0038] like Figure 3 As shown, the difference between this embodiment and the above embodiments is that the mounting bracket 1 includes an upper frame 10 and a lower support part 11. The lower support part 11 is installed below the upper frame 10 and is used to support the upper frame 10. The support plate 6 is installed at the bottom of the lower support part 11. A sliding mechanism is installed on the mounting bracket 1. The sliding mechanism is installed on the upper frame 10. The mounting rod 2 is installed on the sliding mechanism. The sliding mechanism is used to drive the mounting rod 2 to move in the horizontal plane. Compared with the above two embodiments, this embodiment can achieve the tightening of bolts at different positions without moving the mounting bracket 1.

[0039] Specifically, the sliding mechanism includes a first slide rail 8 and a slider slidably mounted on the first slide rail 8. The first slide rail 8 is mounted on the mounting bracket 1, and the mounting rod 2 is mounted on the first slider 9 by bolts or other components. A first fixing component is detachably installed between the first slider 9 and the first slide rail 8. The first fixing component can be a bolt or a fixing pin or other components. The first slider 9 is fixed on the first slide rail 8 by the first fixing component.

[0040] Preferably, two sets of parallel second slide rails 12 are installed on the mounting frame 1. The second slide rails 12 can be installed on the upper frame 10 of the mounting frame 1 by fasteners such as bolts or screws. A second slider 13 is slidably installed on each set of second slide rails 12. A connecting rod 14 is provided between the two sets of second sliders 13. The connecting rod 14 is fixed to the slider by locking parts such as screws. The first slide rail 8 can be installed on the connecting rod 14 by screws or other components of the prior art. A second fixing part is provided between each set of second sliders 13 and each set of second slide rails 12. The second slide rail 12 is perpendicular to the first slide rail 8, thereby enabling the elastic block 3 to move on the X-axis, Y-axis and Z-axis, thereby realizing the working scenario adapted by the tooling.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
