Description

Technical Field

[0001] This utility model relates to the technical field of semi-trailer testing equipment, and in particular to a semi-trailer axle offset angle testing device. Background Technology

[0002] Currently, a typical crankshaft consists of a central shaft and a retaining ring for positioning. Inspecting the quality of a crankshaft requires measuring various data points, one crucial aspect being the crankshaft's eccentricity angle. Existing technology often uses specialized tooling to measure this eccentricity angle, but this tooling is frequently not very versatile and has a complex structure.

[0003] To address the aforementioned problems, prior art CN208269805U discloses a crankshaft eccentricity angle measuring instrument, comprising a horizontally arranged crankshaft mounting base, a lever gauge fixing base obliquely arranged to the left front of the crankshaft mounting base, and a lever dial indicator mounted on the lever gauge fixing base. The product crankshaft is placed on the crankshaft mounting base, and the contact of the lever dial indicator mates with the central axis of the product crankshaft. This invention can be used in the technical field of workpiece inspection.

[0004] However, in the aforementioned prior art, during the process of detecting the axle offset angle of a semi-trailer, after one end is tested, it needs to be removed and reinstalled before the other end can be tested, which is inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a semi-trailer axle offset angle detection device, which solves the technical problem in the prior art that after detecting the axle offset angle of a semi-trailer, it is necessary to remove it and reinstall it before the other end can be detected, which is inconvenient to use.

[0006] To achieve the above objectives, this utility model employs a semi-trailer axle offset detection device, comprising a base, a detection mechanism, and a placement structure. The placement structure includes two hydraulic telescopic rods, a fixed base, a rotating assembly, a clamping component, a placement platform, and two clamping arms. The detection mechanism is fixedly connected to the base and located at one end of the base. The two hydraulic telescopic rods are fixedly connected to the base and symmetrically arranged at one end of the base. The fixed base is fixedly connected to the two hydraulic telescopic rods and located at their upper ends. The rotating assembly, the clamping component, and the placement platform are respectively disposed on the fixed base. The placement platform is fixedly connected to the rotating assembly and located at one end of the rotating assembly. One end of the clamping component is rotatably connected to the rotating assembly. The clamping component and the two clamping arms are respectively disposed on the placement platform. The two clamping arms are slidably connected to the clamping component and symmetrically arranged at one end of the clamping component.

[0007] The rotating assembly includes a rotary motor and a rotating shaft, with the rotating shaft fixedly connected to the output end of the rotary motor.

[0008] The clamping component includes a servo motor, a worm gear, a worm wheel, a transmission component, a moving roller, and a sliding component. The moving roller has several toothed blocks, which are evenly distributed on the moving roller. The worm gear is fixedly connected to the output end of the servo motor. The transmission component is fixedly connected to the worm wheel and located at one end of the worm wheel. The moving roller is slidably connected to the rotating shaft and located at one end of the rotating shaft. The sliding component and the transmission component respectively cooperate with the moving roller, and the worm wheel cooperates with the worm gear.

[0009] The transmission component includes a support rod and a gear, wherein the gear is fixedly connected to the support rod and is located at one end of the support rod.

[0010] The sliding component includes a second gear and a bidirectional screw, the bidirectional screw being fixedly connected to the second gear and located at one end of the second gear.

[0011] This utility model discloses a semi-trailer axle offset angle detection device. In practical use, the axle is placed on the placement platform, and the clamping member drives the two clamping arms to move relative to each other, thereby fixing and clamping the axle. Then, the detection mechanism detects the offset angle. When it is necessary to detect the other end, the two hydraulic telescopic rods move the fixed seat upward, and then the rotating component drives the placement platform to rotate, thereby causing the axle to rotate. At this time, since the axle is fixedly clamped by the two clamping arms, one end of the clamping member rotates simultaneously through the two clamping arms. After rotation, the two hydraulic telescopic rods retract the fixed seat to its original position, thereby allowing the other end of the axle to be detected. This method effectively solves the problem that in the process of detecting the offset angle of a semi-trailer axle, after detecting one end, it is necessary to remove and reinstall it before the other end can be detected, which is inconvenient to use.

[0020] This utility model provides a semi-trailer axle misalignment detection device, including a base 101, a detection mechanism 102, a hydraulic telescopic rod 103, a fixed seat 104, a placement platform 105, a clamping arm 106, a rotary motor 107, a rotating shaft 108, a servo motor 109, a worm gear 110, a worm wheel 111, a moving roller 112, a toothed block 113, a support rod 114, a first gear 115, a second gear 116, and a bidirectional screw 117. The aforementioned solution solves the problem that in the process of detecting the axle misalignment of a semi-trailer, after detecting one end, it is necessary to disassemble and reinstall it before the other end can be detected, which is inconvenient to use.

[0021] In this specific embodiment, the detection mechanism 102 is fixedly connected to the base 101 and located at one end of the base 101. Two hydraulic telescopic rods 103 are fixedly connected to the base 101 and symmetrically arranged at one end of the base 101. The fixed base 104 is fixedly connected to the two hydraulic telescopic rods 103 and located at the upper end of the two hydraulic telescopic rods 103. The rotating assembly, the clamping member, and the placement platform 105 are respectively disposed on the fixed base 104. The placement platform 105 is fixedly connected to the rotating assembly and located at one end of the rotating assembly. One end of the clamping member is rotatably connected to the rotating assembly. The clamping member and two clamping arms 106 are respectively disposed on the placement platform 105. The two clamping arms 106 are slidably connected to the clamping member and symmetrically arranged at the placement platform 105. At one end of the clamping member, the detection mechanism 102 is provided by the prior art. The axle is placed on the placement platform 105, and the clamping member drives the two clamping arms 106 to move relative to each other, thereby fixing and clamping the axle. Then, the detection mechanism 102 detects the deflection angle. When it is necessary to detect the other end, the two hydraulic telescopic rods 103 move the fixed seat 104 upward, and then drive the placement platform 105 to rotate through the rotating assembly, thereby driving the axle to rotate. At this time, since the axle is fixedly clamped by the two clamping arms 106, the two clamping arms 106 drive one end of the clamping member to rotate simultaneously. After the rotation is completed, the two hydraulic telescopic rods 103 retract the fixed seat 104 to its original position, thereby allowing the other end of the axle to be detected, which facilitates the detection of the deflection angle at both ends of the axle.

[0022] The rotating assembly includes a rotary motor 107 and a rotating shaft 108. The rotating shaft 108 is fixedly connected to the output end of the rotary motor 107, and the rotary motor 107 drives the rotating shaft 108 to rotate.

[0023] Secondly, the clamping component includes a servo motor 109, a worm gear 110, a worm wheel 111, a transmission component, a moving roller 112, and a sliding component. The moving roller 112 has a plurality of tooth blocks 113, which are evenly arranged on the moving roller 112. The worm gear 110 is fixedly connected to the output end of the servo motor 109. The transmission component is fixedly connected to the worm wheel 111 and is located at one end of the worm wheel 111. The moving roller 112 is slidably connected to the rotating shaft 108 and is located at one end of the rotating shaft 108. The sliding component and the transmission component are respectively engaged with the moving roller 112. The worm wheel 111 is engaged with the worm gear 110. The servo motor 109 drives the worm gear 110 to rotate. The worm gear 110 drives the worm wheel 111 to rotate. The worm wheel 111 drives the transmission component to rotate. The transmission component drives the moving roller 112 to move. The moving roller 112 drives the sliding component to rotate.

[0024] Meanwhile, the transmission component includes a support rod 114 and a gear 115. The gear is fixedly connected to the support rod 114 and is located at one end of the support rod 114. The gear 115 is mounted on the support rod 114.

[0025] In addition, the sliding component includes a second gear 116 and a bidirectional screw 117. The bidirectional screw 117 is fixedly connected to the second gear 116 and is located at one end of the second gear 116. The bidirectional screw 117 is mounted on the second gear 116.

[0026] In the specific use of the semi-trailer axle offset angle detection device according to this embodiment, the axle is placed on the placement platform 105. The servo motor 109 drives the worm gear 110 to rotate, the worm gear 110 drives the worm wheel 111 to rotate, and the worm wheel 111 drives the gear 115 to rotate via the support rod 114. Since the distance between the two gear blocks 113 is matched with the tooth pitch of the gear 115 and the gear 116, the gear 115 drives the moving roller 112 to move, the moving roller 112 drives the gear 116 to rotate, the gear 116 drives the bidirectional screw 117 to rotate, and the bidirectional screw 117 drives the two gears 115 to rotate. The clamping arms 106 move relative to each other to clamp the axle. When the other end needs to be inspected, the two hydraulic telescopic rods 103 move the fixed seat 104 upward. Then, the rotary motor 107 drives the placement platform 105 to rotate through the rotating shaft 108. At this time, since the axle is fixedly clamped by the two clamping arms 106, the gear 116 rotates along the moving roller 112 during the rotation of the placement platform 105. The moving roller 112 does not move or rotate. After the rotation is completed, the two hydraulic telescopic rods 103 retract the fixed seat 104 to its original position, so as to inspect the other end of the axle and facilitate the inspection of the deflection angle at both ends of the axle.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
