[0002] Automotive inspection fixtures are tools used to measure and inspect manufactured parts and assemblies to ensure the accuracy and quality of parts during the production process. When automotive inspection fixtures are used to inspect large-sized parts and need to inspect their central parts, a bracket is generally set on the inspection table, a crossbeam is set on the bracket, and a positioning pin is fixed on the crossbeam. The automotive parts to be inspected are placed under the crossbeam on the inspection table before inspection. At the same time, in order to facilitate the removal of parts, the crossbeam needs to be detachably fixed.

[0003] In order to ensure the installation stability of the positioning sheath on the crossbeam during the inspection of automobile parts, the crossbeam is generally made of steel and is heavy. When multiple parts are continuously inspected, the crossbeam needs to be frequently removed to facilitate the removal and installation of large-sized parts on the inspection table. Since the steel material of the crossbeam is heavy, other auxiliary installation equipment is required when installing and removing the crossbeam, or multiple people are required to complete the installation and removal work together, which not only causes inconvenience in use, but also wastes manpower and leads to low work efficiency.

[0004] Based on this, it is necessary to design a gauge with a crossbeam structure, which can be easily and quickly disassembled during the installation and removal of the parts to be inspected, so as to improve work efficiency. Utility Model Content

[0005] In order to solve the problem in the prior art that other auxiliary installation equipment or multiple people are required to install and remove the crossbeam, resulting in low work efficiency, the utility model provides a gauge with a crossbeam structure.

[0008] Furthermore, the driving component is a handle, and the handle rotates coaxially with the rotating shaft, and the rotation of the handle is used to drive the crossbeam to rotate based on the hinge point.

[0009] Furthermore, the diameter of the driving wheel is greater than the diameter of the driven wheel.

[0010] Furthermore, it also includes a damping component, one end of which is arranged on the bracket, and the other end is connected to the driving wheel, and the damping component is used to slow down the rotation of the driving wheel.

[0011] Furthermore, the damping assembly includes a damper and a rack, the rack is slidably arranged in the bracket, the damper is arranged in the first bracket, the rack is meshed with the driving wheel, the bottom of the rack is connected to the damper action section, the damper action section moves in the same direction as the rack, and the damper is used to slow down the rotation of the driving wheel.

[0012] Furthermore, the handle is detachably connected to the rotating shaft.

[0013] Furthermore, a handle is provided on one side of the crossbeam close to the hinge point, and the handle is used to assist the crossbeam in rotating.

[0014] Furthermore, it also includes a second bracket, which is used to limit the end of the beam away from the hinge point.

[0015] The beneficial effects of the utility model are as follows: by hingedly connecting one end of the crossbeam to the top of the first bracket, the crossbeam can rotate based on the hinge point with the first bracket, and a driven wheel and a driving wheel are respectively arranged on the crossbeam and the first bracket, and the driving wheel is driven to rotate by rotating the handle, and the driven wheel is driven to rotate by the rotation of the driving wheel, so that the crossbeam rotates with the rotation of the handle, and the other end of the crossbeam is lifted and lowered.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-4 As shown, a check fixture with a crossbeam structure includes a first bracket 10 and a crossbeam 3, a driven wheel 6 is fixedly arranged on the crossbeam 3, a driving wheel 7 is rotatably connected to the first bracket 10 through a rotating shaft 4, the rotating shaft 4 passes through the side wall of the first bracket 10, the center of the driven wheel 6 on the crossbeam 3 is hinged to the first bracket 10 and the driving wheel 7 is meshed with the driven wheel 6, and a driving assembly is transmission-connected to the rotating shaft 4, and the driving assembly is used to drive the crossbeam 3 to rotate based on the hinge point;

[0024] Since the installation stability of the positioning sheath on the cross beam 3 needs to be ensured during the inspection of automobile parts, the cross beam 3 is generally made of steel and is heavy. When multiple parts are continuously inspected, the cross beam 3 needs to be frequently removed to facilitate the removal and installation of large-sized parts on the inspection table. Since the steel material of the cross beam 3 is heavy, other auxiliary installation equipment is required when installing and removing the cross beam 3, or multiple people are required to complete the installation and removal work together, which not only causes inconvenience in use, but also wastes manpower and leads to low work efficiency.

[0025] Therefore, in the present embodiment, one end of the cross beam 3 is hinged to the top of the first bracket 10, so that the cross beam 3 can rotate based on the hinge point with the first bracket 10, the driven wheel 6 is fixedly arranged on the side of the cross beam 3, and the driving wheel 7 is rotatably connected to the side wall of the first bracket 10 through the rotating shaft 4, the rotating shaft 4 is located on the inner side of the first bracket 10 and is linked to the driving wheel 7, and is located on the outer side of the first bracket 10 and is connected to the handle 5, so that the driving wheel 7 rotates with the rotation of the handle 5, and the driving wheel 7 is driven to rotate by rotating the handle 5, and the driven wheel 6 is driven to rotate by the rotation of the driving wheel 7, so that the cross beam 3 rotates with the rotation of the handle 5, so that the other side of the cross beam 3 is realized. The lifting and lowering of the cross beam 3 are performed during the inspection process. The other end of the cross beam 3 is lifted by rotating the handle 5 to form an installation channel for automobile parts. Then, the automobile parts to be inspected are placed on the inspection table. Subsequently, the other end of the cross beam 3 is slowly lowered by rotating the handle 5. The hole positions on the automobile parts to be inspected are inspected by the locating pins installed on the cross beam 3. Since one end of the cross beam 3 is hinged to the first bracket 10, on the one hand, the disassembly and assembly of the cross beam 3 during the inspection of bicycle parts can be facilitated. On the other hand, after one end of the cross beam 3 is hinged, it is not easy to be displaced, which can ensure the installation accuracy of the cross beam 3, thereby improving the work efficiency and the inspection accuracy.

[0026] Since the cross beam 3 is generally made of steel, the cross beam 3 is heavy. Even if one side of the cross beam 3 is hinged to the first bracket 10, the operator only needs to lift one end of the cross beam 3 by the handle 5 during operation. However, in order to reduce the workload of the operator and improve the safety of the equipment operation, in one embodiment, the diameter of the driving wheel 7 is larger than the diameter of the driven wheel 6.

[0027] The principle of the driving wheel 7 driving the driven wheel 6 is to use the change of gear teeth between gears of different sizes to achieve the conversion of speed and torque. The number of teeth and the size of the gear radius between the driving wheel 7 and the driven wheel 6 are different. When the driving wheel 7 rotates, its teeth will mesh with the teeth of the driven wheel 6, thereby transmitting power to the driven wheel 6, thereby achieving the conversion of speed and torque. Generally speaking, when the number of gears of the driving wheel 7 is large and the gear radius is large, the speed will slow down, but the torque output by the gear system will increase, while the driven wheel 6 is the opposite. Therefore, in this embodiment, the driven wheel 6 is driven by the driving wheel 7 to rotate, which can increase the torque, so the staff can use less force to drive the beam 3 to rotate, and at the same time, it can avoid the risk of slipping out of the hand due to the heavy weight of the beam 3, effectively improving the safety of the equipment.

[0028] Since the cross beam 3 is heavy, although the driving wheel 7 drives the driven wheel 6 in the above embodiment to increase the torque, there is no safety device to prevent the cross beam 3 from falling directly during the rotation process, and there are still safety hazards in the use process, which may not only cause damage to the equipment, but also cause injuries to the staff. Therefore, in one embodiment, a damping component is also included, one end of the damping component is arranged on the first bracket 10, and the other end is connected to the driving wheel 7, and the damping component is used to reduce the rotation speed of the driving wheel 7;

[0029] The damping component is connected to the driving wheel 7, so that after the driving wheel 7 drives the cross beam 3 to be lifted, even if the staff accidentally drops it, the driving wheel 7 can be applied with a buffer force to reduce the rotation speed of the driving wheel 7, thereby greatly reducing the falling speed of the cross beam 3. Its working principle is similar to that of a damping hinge. At the same time, although the damping component connected to the driving wheel 7 will also generate resistance when the cross beam 3 is lifted, it can be known from the working principle of a general damping component that the resistance generated by the damping component is smaller when a slower moving speed is applied to it, and its resistance will increase when a faster moving speed is applied to it. When the cross beam 3 is lifted, since the cross beam 3 itself is heavier, the staff will lift the cross beam 3 by turning the handle 5 for safety reasons, that is, the damping component has less influence on the lifting of the cross beam 3.

[0030] Since the general damping component will connect its action section to the gear wheel during installation, so that the gear drives the action section to form a mechanism similar to a crank rocker, although it can apply resistance to the driving wheel 7 and make the driving wheel 7 rotate quickly, the size of the driving wheel 7 installed in the first bracket 10 is limited, so the damping component is formed shorter. When the crossbeam 3 needs to be lifted and the handle 5 needs to be rotated a large number of times, the action of the driving wheel 7 on the action section of the damping component is a reciprocating motion, that is, the buffering direction is frequently changed, and because the gear rotates to different positions, the action section of the damping component will also swing in different directions, so the buffering effect is poor. In order to ensure the use effect of the damping component, in one embodiment, the damping component includes a damper 9 and a rack 8, the rack 8 is slidably arranged in the first bracket 10, the damper 9 is arranged in the first bracket 10, the rack 8 is meshed with the driving wheel 7, the bottom of the rack 8 is connected to the action section of the damper 9, and the damper 9 is used to reduce the rotation speed of the driving wheel 7;

[0031] The rack 8 is meshed with the driving wheel 7. No matter how many times the driving wheel 7 rotates in the same direction, the rack 8 can only move in one direction. The rack 8 is connected to the action section of the damper 9, so that the action section of the damper 9 moves with the movement of the rack 8. When the crossbeam 3 is lifted, the rack 8 is lifted upward under the rotation drive of the driven wheel 6 and the driving wheel 7. When the crossbeam 3 is installed and lowered, the rack 8 is pressed downward and the action section of the damper 9 moves downward to form a buffering force. The action section of the damper 9 is the movable telescopic part of the damper 9. The reverse transmission from the rack 8 to the driving wheel 7 and then to the driven wheel 6 causes the crossbeam 3 to slowly descend. At the same time, a limit block is arranged inside the first bracket 10 at the highest point of the rack 8 to prevent the rack 8 from falling off, thereby improving the safety of the equipment.

[0032] Since the handle 5 is connected to the rotating shaft 4, the connection of the handle 5 to the rotating shaft 4 may affect the inspection work of automobile parts when the cross beam 3 does not need to be disassembled. Therefore, in order to avoid the influence of the handle 5 on the inspection work and improve the inspection efficiency of automobile parts, in one embodiment, the handle 5 and the rotating shaft 4 are detachably connected; a straight-line protrusion is provided on the rotating shaft 4 at the connection position with the handle 5, and a straight-line groove cooperating with the above-mentioned straight-line protrusion is also provided at the connection position between the handle 5 and the rotating shaft 4. When the two are abutted against each other, the rotating shaft 4 can be driven by the handle 5, and then the driving wheel 7 can be driven to rotate. When the cross beam 3 needs to be disassembled, the handle 5 is connected to the rotating shaft 4, and when the cross beam 3 does not need to be disassembled, the handle 5 is removed.

[0033] Since the handle 5 drives the driving wheel 7 to rotate, the driving wheel 7 drives the driven wheel 6 on the beam 3 to rotate, so the driving wheel 7 and the driven wheel 6 rotate in different directions. It can be seen from the figure that if one end of the beam 3 is to be lifted, Figure 3 and Figure 4 In the perspective of , the driven wheel 6 rotates counterclockwise, and the driving wheel 7 rotates clockwise, so the staff also needs to operate the handle 5 to rotate clockwise, and the staff's force application direction is to push upward, which makes it difficult to apply force. In order to facilitate the staff to apply force to the handle 5, in one embodiment, a handle 1 is provided on the side of the crossbeam 3 close to the hinge point, and the handle 1 is used to assist the crossbeam 3 in rotating;

[0034] After the handle 1 is provided on the beam 3, when the beam 3 needs to be lifted, the worker pushes the handle 5 upward with one hand and pulls the handle 1 with the other hand to apply force in the opposite direction. Then, the two opposite forces can simultaneously form a combined force to lift the beam 3, which can not only balance the worker's body, but also provide a greater force on the beam 3, so that one end of the beam 3 can be lifted more conveniently.

[0035] In one embodiment, a second bracket 2 is further included. The second bracket 2 is used to limit the end of the beam 3 away from the hinge point. The second bracket 2 can provide support for the other end of the beam 3 when the beam 3 is lowered for installation, thereby preventing the end of the beam 3 hinged to the first bracket 10 from being subjected to stress for a long time and causing a decrease in accuracy. At the same time, it can also prevent the beam 3 from gradually falling away from the hinge end due to its heavy weight, thereby improving the safety and accuracy of the equipment.

[0036] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
