Description

Technical Field

[0001] This utility model belongs to the field of automotive repair tools, and specifically relates to a heavy-duty clamp for removing automotive wheel hub bolts. Background Technology

[0002] Currently, wheel bolt removal is a common operation in automobile repair and maintenance. However, due to factors such as vibration during vehicle operation, high temperature in the wheel hub area, and long-term exposure to the external environment such as rainwater and salt corrosion, wheel bolts are prone to rust and corrosion, which greatly increases the difficulty of removal. Traditional removal tools, such as ordinary wrenches and socket wrenches, have many limitations. Ordinary wrenches rely on manual torque, and when faced with severely rusted bolts, the torque applied manually is often insufficient to overcome the tightening force of the bolts, making the removal work time-consuming, labor-intensive, and inefficient.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a heavy-duty clamp for removing automobile wheel hub bolts, which solves the problem that traditional disassembly tools, such as ordinary wrenches and socket wrenches, have many limitations. Ordinary wrenches rely on human power to provide torque. When faced with severely rusted bolts, the torque applied by human power is often insufficient to overcome the tightening force of the bolts, making the disassembly work consume a lot of time and energy and is inefficient. Utility Model Content

[0004] This utility model proposes a heavy-duty clamp for removing automotive wheel hub bolts, which solves the problem that traditional disassembly tools, such as ordinary wrenches and socket wrenches, have many limitations. Ordinary wrenches rely on manual torque, and when faced with severely rusted bolts, the torque applied by manual force is often insufficient to overcome the bolt's tightening force, making the disassembly work consume a lot of time and effort and is inefficient.

[0005] The technical solution of this utility model is implemented as follows: a heavy-duty clamp for removing automobile wheel hub bolts includes: a rod mechanism with an internal hollow structure, an adjusting rod with a screw structure rotatably connected inside the rod mechanism, a knob fixedly connected to the right side of the adjusting rod, and anti-slip grooves arranged in a ring array on the outer circumference of the knob;

[0006] Guide blocks are fixedly connected in a ring array on the inner wall of the rod mechanism. Movable components are inserted into the inner side of the rod mechanism and the guide blocks. The movable components have screw holes that match the adjusting rod inside. A connecting plate is fixedly connected to the left end face of the movable components. The outer circumferential surface of the connecting plate has notches arranged in a ring array.

[0007] In a preferred embodiment, a mounting bracket is fixedly connected to the outer peripheral surface of the rod mechanism. There are two mounting brackets, which are fixedly connected to the upper and lower sides of the outer peripheral surface of the rod mechanism in opposite directions.

[0008] In a preferred embodiment, the inner sides of both mounting brackets are provided with notches, and a gripping rod is hinged inside the notch. The gripping rod has a cylindrical structure.

[0009] In a preferred embodiment, a limiting ball is fixedly connected to the outer peripheral surface of the grip rod, and the limiting ball and the grip rod together form a grip structure.

[0010] In a preferred embodiment, the left end of the rod mechanism is fixedly connected to a ring-shaped support disk, and the outer circumferential surface of the support disk is provided with notches arranged in a ring array.

[0011] In a preferred embodiment, the support disk is internally hinged with a gripper mechanism. There are four gripper mechanisms in total, which are arranged in a circular array and hinged inside the support disk.

[0012] In a preferred embodiment, each of the four gripper mechanisms has a clamping part fixedly connected to its inner side. The side of the clamping part away from the gripper mechanism has grooves arranged in a straight line array. The inner side of the gripper mechanism has two connecting plates fixedly connected to each other. A connecting rod assembly is rotatably connected to the notch opened on the outer circumference of the connecting plate. The side of the connecting rod assembly away from the connecting plate is hinged to the connecting plate.

[0013] After using the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, through the coordinated action of components such as the adjusting rod, movable component, connecting plate, and connecting rod assembly, the force of rotating the knob is converted into the clamping force of the gripper mechanism on the wheel hub bolt. Compared with the traditional ordinary wrench that relies solely on human power to directly apply torque to the bolt, this greatly improves the torque transmission efficiency. When facing severely corroded bolts, traditional wrenches may require multiple attempts and a lot of manpower to loosen the bolts. However, this clamp only requires maintenance personnel to easily rotate the knob to quickly clamp the bolts and apply sufficient torque, which greatly shortens the disassembly time, significantly improves work efficiency, and reduces the labor intensity of maintenance personnel.

[0015] 2. In this utility model, four gripper mechanisms are distributed around the wheel hub bolts, and the groove design on the clamping part increases the friction with the bolts, making the clamps more stable when clamping the bolts. This effectively avoids the situation where the bolt head slips or is damaged due to insufficient clamping during the disassembly process, which is common with traditional wrenches. At the same time, the support plate and mounting bracket provide stable support for the clamps as a whole, reducing the risk of damage to other parts of the wheel hub during disassembly, extending the service life of the wheel hub and bolts, and reducing maintenance costs.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, a heavy-duty clamp for removing automobile wheel hub bolts includes: a rod mechanism 1 with an internal hollow structure, an adjusting rod 2 with a screw structure rotatably connected inside the rod mechanism 1, a knob 201 fixedly connected to the right side of the adjusting rod 2, and anti-slip grooves arranged in a ring array on the outer circumference of the knob 201.

[0026] Guide blocks 1014 are fixedly connected in a ring array on the inner wall of the rod mechanism 1. Movable components 2011 are inserted into the inner side of the rod mechanism 1 and the guide blocks 1014. The interior of the movable components 2011 is provided with screw holes that match the adjusting rod 2. A connecting plate 2013 is fixedly connected to the left end face of the movable components 2011. The outer circumferential surface of the connecting plate 2013 is provided with notches in a ring array.

[0027] Among them, a mounting bracket 101 is fixedly connected to the outer peripheral surface of the rod mechanism 1. There are two mounting brackets 101, which are fixedly connected to the upper and lower sides of the outer peripheral surface of the rod mechanism 1 in opposite directions. The inner side of the two mounting brackets 101 is provided with a notch. A gripping rod 1011 is hinged inside the notch. The gripping rod 1011 is a cylindrical structure. The inner side of the four gripper mechanisms 3 is fixedly connected with a clamping part 301. The side of the clamping part 301 away from the gripper mechanism 3 has grooves in a straight array. The inner side of the gripper mechanism 3 is fixedly connected to two connecting plates 3011 in opposite directions. The notch on the outer peripheral surface of the connecting plate 2013 is rotatably connected to a connecting rod assembly 3012. The side of the connecting rod assembly 3012 away from the connecting plate 2013 is hinged to the connecting plate 3011. A guide groove 2012 is provided on the outer peripheral surface of the movable component 2011.

[0028] Among them, a limiting ball 1012 is fixedly connected to the outer peripheral surface of the gripping rod 1011. The limiting ball 1012 and the gripping rod 1011 together form a gripping structure. A ring-shaped support plate 1013 is fixedly connected to the left end of the rod mechanism 1. The outer peripheral surface of the support plate 1013 has notches arranged in a ring array. A gripper mechanism 3 is hinged inside the support plate 1013. There are four gripper mechanisms 3 in total. The four gripper mechanisms 3 are arranged in a ring array and hinged inside the support plate 1013.

[0029] When in use, the maintenance personnel first hold the grip rod 1011 and determine the position of the wheel hub bolt to be removed by observation or other means. The limiting ball 1012 fixedly connected to the outer circumference of the grip rod 1011 can prevent the hand from accidentally slipping during the gripping process and ensure operational safety.

[0030] Align the support plate 1013 at the left end of the rod mechanism 1 with the hub bolt, so that the four gripper mechanisms 3 are distributed around the bolt. The notches on the outer circumference of the support plate 1013 are arranged in a ring array. On the one hand, the weight of the support plate 1013 is reduced, and on the other hand, it can be used as an auxiliary force point in some cases or for installing other auxiliary components if needed.

[0031] When maintenance personnel rotate knob 201, the anti-slip grooves arranged in a ring on the outer circumference of knob 201 increase the friction between the hand and knob 201, making it easier to apply force. Since the adjusting rod 2 is fixedly connected to knob 201, the rotation of knob 201 drives the adjusting rod 2 to rotate. The adjusting rod 2 is a screw structure that matches the screw hole inside the movable component 2011. The movable component 2011 will move along the axial direction of the rod mechanism 1 under the rotation of the adjusting rod 2. The guide block 1014, which is fixedly connected in a ring on the inner wall of the rod mechanism 1, is inserted into the movable component 2011. It can guide and limit the movement of the movable component 2011, ensuring that the movable component 2011 moves smoothly along the axial direction without deviation or rotation.

[0032] As the movable component 2011 moves, the connecting plate 2013 fixedly connected to its left end also moves synchronously. The grooves arranged in a ring array on the outer circumference of the connecting plate 2013 provide a position for the connecting rod assembly 3012 to rotate. One end of the connecting rod assembly 3012 rotates in the groove of the connecting plate 2013, and the other end is hinged to two connecting plates 3011 fixedly connected to the inner side of the gripper mechanism 3. When the connecting plate 2013 moves, the connecting plate 3011 is driven to move through the transmission of the connecting rod assembly 3012, thereby causing the gripper mechanism 3 to rotate around its hinge point with the support plate 1013. The four gripper mechanisms 3 move synchronously and gradually move closer to the center, so that the clamping part 301 fixed to the inner side of the gripper mechanism 3 clamps the hub bolt. The grooves arranged in a straight array on the side of the clamping part 301 away from the gripper mechanism 3 can increase the contact friction with the bolt, prevent the bolt from slipping during disassembly, and ensure a firm clamping.

[0033] The maintenance personnel hold the grip lever 1011 and apply torque to the wheel hub bolt by rotating the entire clamp, using the lever principle. Since the clamping mechanism 3 has firmly clamped the bolt and the entire clamp structure is reasonably designed, compared with the traditional ordinary wrench that relies on manpower to directly apply torque to the bolt, this heavy-duty clamp can more effectively convert manpower into the disassembly force of the bolt, overcome the large tightening force caused by the rust and corrosion of the bolt, and achieve easy disassembly.
