Description

Technical Field

[0001] This utility model relates to the field of heavy truck component testing technology, and in particular to a heavy truck frame beam testing fixture. Background Technology

[0002] As a key load-bearing component of the heavy truck chassis, the crossbeam of the heavy truck frame directly affects the overall performance and safety of the heavy truck. Stable clamping and precise positioning are required through tooling to ensure the testing effect.

[0003] However, in the existing technology, some heavy truck frame beam inspection fixtures lack effective transmission guidance and support structures. The transmission components are prone to deviation or shaking during operation, resulting in inaccurate beam clamping position and affecting the reliability of inspection data. At the same time, some core transmission components such as lead screws of some fixtures are prone to bending deformation after long-term stress due to insufficient structural strength, which not only reduces the stability of the fixture operation but also shortens the service life of the fixture. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of poor transmission guidance, insufficient strength of core components, and unstable operation of transmission rods in the existing technology, which lead to inaccurate clamping of crossbeams, short tooling life, and low detection efficiency. Therefore, a heavy truck frame crossbeam detection tooling is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heavy truck frame crossbeam inspection fixture, comprising a support frame, a clamping mechanism rotatably mounted on one side of the support frame, the clamping mechanism comprising a guide rod and a clamping plate, the clamping plate being fixedly mounted on the end of the guide rod, a positioning plate being fixedly mounted on one side of the support frame, the guide rod being slidably connected to the positioning plate, the two clamping plates being arranged opposite to each other, a connecting block being rotatably connected to the outer wall of the guide rod, a transmission rod being slidably connected to both sides of the connecting block, a slider being rotatably connected to the end of the transmission rod, a motor screw transmission assembly being fixedly mounted on one side of the support frame, the motor screw transmission assembly having two sections of threaded groove on the screw, and the two sections of threaded groove being arranged in opposite directions, the slider being threadedly connected to the screw of the motor screw transmission assembly.

[0006] Preferably, a limiting block is rotatably installed on the inner side of the end of the transmission rod, and the limiting block is slidably connected to the connecting block.

[0007] Preferably, a strip groove is provided at the junction of the connecting block and the limiting block.

[0008] Preferably, a guide ridge is provided on one side of the support frame along its own length and height, and the slider is slidably connected to the guide ridge.

[0009] Preferably, a limiting bearing is fixedly installed on one side of the support frame, and the lead screw of the motor lead screw transmission assembly is rotatably connected to the limiting bearing.

[0010] Preferably, the outer wall of the lead screw in the motor lead screw drive assembly is provided with a thickened portion, which is located between two limiting bearings.

[0011] Preferably, an extension plate is fixedly installed on one side of each of the two positioning plates, and the middle section of the transmission rod is rotatably connected to the extension plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a motor lead screw transmission assembly, the two reverse threaded grooves on the lead screw can drive the two sliders to move synchronously in opposite directions. With the linkage of the transmission rod, connecting block, limit block and guide rod, the clamping plate can automatically and synchronously clamp the crossbeam. This not only greatly improves the clamping efficiency, but also ensures uniform clamping force, effectively avoids detection errors caused by the crossbeam's clamping offset, and improves detection accuracy.

[0013] 2. In this utility model, a multi-dimensional stable protection structure is formed by the sliding guidance of the guide rod by the positioning plate, the movement limitation of the slider by the guide convex strip, the support of the motor lead screw transmission assembly lead screw by the limit bearing, the strength enhancement of the lead screw by the thickened part, and the rotational support of the transmission rod by the extension plate. This reduces mechanical jamming and component deformation problems during the tooling operation, extends the service life of the tooling, and further improves the stability of transmission and clamping, ensuring that the testing operation is carried out continuously and efficiently.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a heavy truck frame crossbeam inspection fixture, including a support frame 1. A clamping mechanism 2 is rotatably installed on one side of the support frame 1. The clamping mechanism 2 includes a guide rod 21 and a clamping plate 22. The clamping plate 22 is fixedly installed at the end of the guide rod 21. A positioning plate 3 is fixedly installed on one side of the support frame 1. The guide rod 21 is slidably connected to the positioning plate 3. The two clamping plates 22 are arranged opposite to each other. A connecting block 23 is rotatably connected to the outer wall of the guide rod 21. A transmission rod 25 is slidably connected to both sides of the connecting block 23. A slider 26 is rotatably connected to the end of the transmission rod 25. A motor screw transmission assembly 4 is fixedly installed on one side of the support frame 1. The screw of the motor screw transmission assembly 4 has two sections of threaded groove, and the two sections of threaded groove are arranged in opposite directions. The slider 26 is threadedly connected to the screw of the motor screw transmission assembly 4. A limit block 27 is rotatably installed on the inner side of the end of the transmission rod 25. The limit block 27 is slidably connected to the connecting block 23. A strip groove 24 is opened at the junction of the connecting block 23 and the limit block 27.

[0019] The specific setup and function of this embodiment are described below. Based on the support frame 1 as the basic support structure, the clamping mechanism 2 is the core component for clamping the crossbeam. Two clamping plates 22 are arranged opposite each other to clamp the heavy truck frame crossbeam from both the top and bottom. The positioning plate 3 provides sliding guidance for the guide rod 21, ensuring that the guide rod 21 moves in a fixed direction. When the motor screw transmission assembly 4 is started, the screw rotation drives the two sliders 26 to move linearly in opposite directions along the screw. The movement of the sliders 26 drives the connecting block 23 through the transmission rod 25. The sliding engagement between the slot 24 and the connecting block 23 ensures that the rotation of the transmission rod 25 is converted into... The axial movement of the guide rod 21 eventually causes the two opposing clamping plates 22 to move closer or further apart, thereby clamping or releasing the crossbeam of the heavy truck frame for subsequent inspection operations. The two-section reverse threaded groove design can drive the two sliders 26 to move synchronously in opposite directions, achieving automatic and synchronous clamping of the crossbeam of the heavy truck frame. Compared with manual clamping, this is more efficient and provides uniform clamping force, avoiding crossbeam clamping offset from affecting inspection accuracy, thus improving the efficiency and stability of the inspection operation. Furthermore, if there is a need to adjust the angle during clamping, the guide rod 21 can be directly rotated with the help of tools to drive the clamping plates 22 and directly adjust the angle of the crossbeam.

[0020] Example 2: Figure 1 and Figure 2 As shown, a guide ridge 7 is provided on one side of the support frame 1 along its own length and height direction. The slider 26 is slidably connected to the guide ridge 7. A limit bearing 5 is fixedly installed on one side of the support frame 1. The screw of the motor screw transmission assembly 4 is rotatably connected to the limit bearing 5. A thickened part 6 is provided on the outer wall of the screw of the motor screw transmission assembly 4. The thickened part 6 is located between the two limit bearings 5. An extension plate 8 is fixedly installed on one side of the two positioning plates 3. The middle section of the transmission rod 25 is rotatably connected to the extension plate 8.

[0021] The overall effect of this embodiment is as follows: the guide ridge 7 provides guidance and limitation for the slider 26 to move axially along the lead screw of the motor lead screw transmission assembly 4, preventing the slider 26 from deviating as the lead screw rotates; the limit bearing 5 is rotatably connected to the lead screw of the motor lead screw transmission assembly 4, providing radial limitation and support for the lead screw, ensuring stable rotation of the lead screw; the thickened part 6 is located between the two limit bearings 5, enhancing the structural strength of this section of the lead screw and preventing the lead screw from bending and deforming under force; the extension plate 8 and the transmission rod 25 provide a rotation fulcrum, enabling the transmission rod 25 to rotate stably around the extension plate 8 under the drive of the slider 26, thereby accurately transmitting power to the clamping mechanism.

[0022] The device is used and operates as follows: Two clamping plates 22 are arranged opposite each other to clamp the crossbeam from the top and bottom. When the motor screw transmission assembly 4 is started, the screw rotates and drives the two sliders 26 to move in opposite directions along the screw. The movement of the sliders 26 drives the transmission rod 25 to move. The transmission rod 25 slides with the limiting block 27 through the slot 24, pushing the connecting block 23 to drive the guide rod 21 to slide along the positioning plate 3. Finally, the two clamping plates 22 move closer or further apart, realizing the clamping and fixing or loosening of the crossbeam for convenient subsequent testing. The guide convex strip 7 is slidably connected to the slider 26, providing guidance and limiting for the slider 26 to move axially along the screw of the motor screw transmission assembly 4, preventing the slider 26 from deviating with the rotation of the screw. The limiting bearing 5 provides radial limiting and support for the screw, ensuring stable rotation of the screw.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
