Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a truck tire bolt grinding machine. Background Technology

[0002] As a core transportation tool in logistics, engineering operations, and other fields, the driving safety and operational efficiency of trucks directly depend on the stability of their chassis components. Tire bolts, as key fasteners connecting tires and wheel hubs, are a crucial link in ensuring the driving safety of trucks. During long-term operation, tire bolts must withstand complex loads such as the vehicle's own weight, road bumps and impacts, and braking torque. At the same time, they are exposed to the outdoor environment and are susceptible to erosion by rainwater, dust, and corrosive substances (such as de-icing agents and road oil stains), leading to problems such as rust, wear, and deformation on the bolt surface. If these faults are not dealt with in time, they may cause tire loosening and abnormal driving noises, or even serious safety accidents such as tire detachment, posing a great threat to road traffic safety. They will also increase truck maintenance costs and downtime, affecting logistics and transportation efficiency.

[0003] Therefore, in response to the needs of rust removal, wear repair, and deformation correction of truck tire bolts, the industry uses efficient and precise specialized grinding equipment to quickly repair faulty bolts, restore their fastening performance, ensure truck driving safety, and reduce operating costs.

[0004] While existing technologies meet user needs to a certain extent, certain shortcomings remain. The installation height of truck tire bolts varies significantly depending on the vehicle model. Equipment with a fixed height cannot adjust the position of the grinding wheel assembly. If the equipment height is lower than the bolt height, the operator needs to hold the bolt or raise the equipment, but the equipment is prone to slipping after being raised, and the grinding wheel cannot be stably aligned with the bolt grinding area, easily resulting in uneven grinding. This leads to the bolt still not being able to fit with the nut after repair. If the equipment height is higher than the bolt height, the operator needs to bend over to lift the bolt to the grinding wheel position or forcibly press the bolt against the grinding wheel with a tool. This not only makes it difficult to control the grinding force but may also lead to over-grinding due to uneven bolt force, reducing bolt strength. After repair, the bolt cannot meet the tightening requirements and instead poses a safety hazard. The specific problems are as follows. Based on this, this utility model designs a truck tire bolt grinding wheel machine to solve the above problems. Utility Model Content

[0005] This utility model provides a truck tire bolt grinding machine, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a truck tire bolt grinding wheel machine, comprising a grinding wheel assembly, a base provided on the surface of the grinding wheel assembly, a column provided on the surface of the base, the grinding wheel assembly mounted on the surface of the column, a fixed guide post fixedly connected to the surface of the base, a guide post sliding groove cooperating with the fixed guide post being opened inside the column, a screw bearing seat fixedly connected inside the column, a lifting screw being rotatably connected to the surface of the screw bearing seat, and a screw mating thread groove cooperating with the lifting screw being opened inside the fixed guide post.

[0007] As a preferred embodiment of the truck tire bolt grinding machine of this utility model, the top end of the lifting screw is fixedly connected to a driven bevel gear, the surface of the column is rotatably connected to a gear shaft, and the end of the gear shaft near the column is fixedly connected to a driving bevel gear that meshes with the driven bevel gear.

[0008] In a preferred embodiment of the truck tire bolt grinding machine of this utility model, an operating rocker arm is fixedly connected to the end of the gear shaft away from the driving bevel gear, and a rocker arm handle is fixedly connected to the end of the operating rocker arm away from the gear shaft.

[0009] As a preferred embodiment of the truck tire bolt grinding machine of this utility model, the surface of the operating rocker arm is provided with anti-slip texture.

[0010] As a preferred embodiment of the truck tire bolt grinding machine of this utility model, the surface of the base is evenly provided with four sets of positioning pin holes, and the surface of the base is slidably connected with movable positioning pins that cooperate with the positioning pin holes.

[0011] As a preferred embodiment of the truck tire bolt grinding machine of this utility model, the bottom end of the movable positioning pin is provided with a positioning pin tip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: It can quickly and accurately raise and lower the grinding wheel assembly by shaking the rocker arm handle to drive the lifting screw according to the bolt height of different vehicle models and maintenance scenarios. This significantly reduces the adjustment time of auxiliary tools, greatly improves overall maintenance efficiency, reduces truck downtime, and eliminates the need for operators to maintain an abnormal posture. Operators can control the fit between the bolt and the grinding wheel by naturally applying force with their arms. This significantly reduces pressure on the shoulder, neck, and waist muscles, making long-term operation less prone to fatigue or occupational injuries. Simultaneously, it improves concentration, allowing for precise control of the grinding process and reducing safety accidents caused by operational errors. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1-4 As shown, this utility model provides a technical solution: a truck tire bolt grinding wheel machine, including a grinding wheel assembly 1, a base 2 on the surface of the grinding wheel assembly 1, a column 3 on the surface of the base 2, the grinding wheel assembly 1 mounted on the surface of the column 3, a fixed guide column 4 fixedly connected to the surface of the base 2, a guide column sliding groove 5 that cooperates with the fixed guide column 4 inside the column 3, a screw bearing seat 6 fixedly connected to the inside of the column 3, a lifting screw 7 rotatably connected to the surface of the screw bearing seat 6, and a screw mating thread groove 8 that cooperates with the lifting screw 7 inside the fixed guide column 4.

[0022] In this implementation plan: the grinding wheel assembly 1 is the key component for performing grinding operations. The base 2 provides basic support for the equipment. The column 3 connects the base 2 and the grinding wheel assembly 1. The fixed guide column 4 cooperates with the guide column sliding groove 5 in the column 3 to play a guiding role and ensure the stability of the lifting and lowering movement of the column 3 and the grinding wheel assembly 1. The screw bearing seat 6 is used to install and support the lifting screw 7 so that it can rotate stably. When the lifting screw 7 rotates, because the fixed guide column 4 has a screw mating thread groove 8 that cooperates with the lifting screw 7, the rotation of the lifting screw 7 will be converted into the linear lifting and lowering movement of the column 3 along the fixed guide column 4 through thread transmission, thereby driving the grinding wheel assembly 1 to rise and fall, adjusting the grinding height, and realizing the stable and precise lifting and lowering adjustment of the grinding wheel assembly 1 to meet the grinding needs of truck tire bolts of different heights. The structure is compact, the transmission is reliable, and the position adaptability of the grinding operation is guaranteed.

[0023] Furthermore:

[0024] In an optional embodiment, a driven bevel gear 9 is fixedly connected to the top end of the lifting screw 7, and a gear shaft 10 is rotatably connected to the surface of the column 3. An active bevel gear 11 that meshes with the driven bevel gear 9 is fixedly connected to one end of the gear shaft 10 near the column 3.

[0025] In this embodiment: the driven bevel gear 9 at the top of the lifting screw 7 meshes with the driving bevel gear 11 at one end of the gear shaft 10 rotatably connected to the surface of the column 3. When the gear shaft 10 rotates, the driving bevel gear 11 rotates accordingly. By using bevel gear meshing transmission, the rotation of the gear shaft 10 is transmitted to the driven bevel gear 9, thereby driving the lifting screw 7 to rotate, providing power input for the lifting screw 7, and realizing the lifting action of the column 3 and the grinding wheel assembly 1.

[0026] Furthermore:

[0027] In an optional embodiment, an operating rocker arm 12 is fixedly connected to the end of the gear shaft 10 away from the driving bevel gear 11, and a rocker arm handle 13 is fixedly connected to the end of the operating rocker arm 12 away from the gear shaft 10.

[0028] In this embodiment: the end of the gear shaft 10 away from the driving bevel gear 11 is connected to the operating rocker arm 12. The rocker arm handle 13 at the end of the operating rocker arm 12 is for the operator to hold. When the operator shakes the rocker arm handle 13, the operating rocker arm 12 makes a circular motion around the axis of the gear shaft 10, driving the gear shaft 10 to rotate. Then, through the meshing transmission of the driving bevel gear 11 and the driven bevel gear 9, the lifting screw 7 is driven to rotate, realizing the lifting control of the grinding wheel assembly 1. The operating rocker arm 12 and the rocker arm handle 13 constitute a manual operating component. Through the lever principle, the operator can drive the gear shaft 10 to rotate by applying a small force, reducing the difficulty of operation, improving the convenience and comfort of operation, and making the equipment easier to manually control and adjust.

[0029] Furthermore:

[0030] In an optional embodiment, the surface of the operating rocker arm 12 is provided with anti-slip texture.

[0031] In this embodiment: the anti-slip texture on the surface of the rocker arm 12 increases the friction between the operator's hand and the rocker arm 12, preventing hand slippage during rocker arm operation and ensuring stable force application, thus making the rotation control of the gear shaft 10 more precise. Furthermore: in an optional embodiment, four sets of positioning pin holes 14 are evenly distributed on the surface of the base 2, and movable positioning pins 15 that cooperate with the positioning pin holes 14 are slidably connected to the surface of the base 2.

[0032] Furthermore:

[0033] In an optional embodiment, four sets of positioning pin holes 14 are evenly provided on the surface of the base 2, and movable positioning pins 15 that cooperate with the positioning pin holes 14 are slidably connected to the surface of the base 2.

[0034] In this embodiment: the four sets of positioning pin holes 14 on the surface of the base 2 cooperate with the movable positioning pins 15 that are slidably connected to the surface of the base 2. When the equipment is installed or used, the movable positioning pins 15 are inserted into the corresponding positioning pin holes 14 to restrict the movement of the base 2 in the horizontal direction. If it is necessary to fix it on the ground or other mounting surfaces, the movable positioning pins 15 can also be inserted into the preset adapter holes on the mounting surface to position and fix the base 2.

[0035] Furthermore:

[0036] In an optional embodiment, the bottom end of the movable positioning pin 15 is provided with a positioning pin tip 16.

[0037] In this embodiment, the positioning pin tip 16 at the bottom of the movable positioning pin 15 is easier to insert into the positioning pin hole 14 or the hole on the mounting surface such as the ground due to the guiding effect of the tip, which reduces the difficulty of alignment and facilitates the quick completion of the positioning operation.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
