Description

Technical Field

[0001] The present application relates to the technical field of transport racks, and in particular to a roller flipping structure for a transport rack. Background Art

[0002] Gauges are simple tools used by industrial manufacturers to control various dimensions of products (such as aperture, space dimensions, etc.), improve production efficiency and control quality, and are suitable for mass-produced products, such as automotive parts, to replace professional measuring tools. When using gauges, attention should be paid to their design and manufacturing, as well as the inspection and weekly inspection of jacking. At the same time, it is also necessary to design the quantity gauge according to the processing measurement needs, and the gauge can only be used after passing the inspection.

[0003] When inspecting a gauge, it is usually necessary to install the gauge on a transport rack, transport the gauge to the vicinity of a coordinate measuring machine through the transport rack, then place the gauge together with the transport rack on the coordinate measuring machine, and then inspect the gauge through the coordinate measuring machine. In order to facilitate the movement of the transport rack, it is usually necessary to install multiple rollers around the bottom of the transport rack, and move the transport rack through the rollers when in use, so as to move the gauge on the transport rack to the specified position.

[0004] When using a three-dimensional coordinate measuring machine to inspect a gauge, the roller itself has a certain height, which will increase the height of the gauge and the frame itself, thereby affecting the accuracy of the three-dimensional coordinate measuring machine's inspection results of the gauge. In order to avoid the influence of the roller height on the inspection results of the three-dimensional coordinate measuring machine, the existing method is to remove the roller. However, when the frame is large, it is cumbersome to remove the roller, and the roller needs to be reinstalled after the inspection of the gauge. The whole process is time-consuming and labor-intensive, which is not conducive to use. Utility Model Content

[0005] In order to achieve the purpose of preventing the roller height from affecting the detection result when using a three-dimensional measuring machine to detect a gauge without removing the roller, the present application provides a roller flipping structure for a transport rack.

[0006] The present application provides a roller flipping structure for a transport rack, which adopts the following technical solution:

[0007] A roller flipping structure for a transport rack comprises a rack body, rollers are arranged around the bottom end of the rack body, wherein a mounting seat is mounted on the rack body, a mounting plate is rotatably connected to the mounting seat, and the rollers are mounted on the mounting plate.

[0008] By adopting the above technical solution, the mounting seat is fixed on the frame during use. In the initial state, the mounting plate abuts against the bottom surface of the mounting seat, the roller is located below the mounting seat, and the roller abuts against the ground. At this time, the roller can be rolled by pushing the frame, so that the inspection fixture on the moving frame can be realized by rolling the roller. When the frame is moved to the vicinity of the three-dimensional coordinate measuring machine, the roller is rotated to the top of the mounting seat by flipping the mounting plate, and then the frame is placed on the three-dimensional coordinate measuring machine, so that the bottom surface of the mounting seat abuts against the three-dimensional coordinate measuring machine, thereby avoiding the roller from directly abutting against the three-dimensional coordinate measuring machine, thereby achieving the purpose of avoiding the roller height affecting the detection structure without removing the roller.

[0009] Preferably, the mounting base includes a plate body fixed on the frame body, a rotating shaft fixed at one end of the plate body, a connecting block is fixed at one end of the mounting plate, the connecting block is rotatably connected to the rotating shaft, and a first limiting structure for limiting the mounting plate is provided at one end of the plate body away from the rotating shaft.

[0010] By adopting the above technical solution, when the mounting plate is rotated to abut against the plate body during use, the mounting plate is limited by the first limiting structure to prevent the mounting plate from rotating away from the plate body, thereby ensuring the stability of the roller installed on the mounting plate when rolling on the ground.

[0011] Preferably, the first limiting structure includes a first plug rod arranged at one end of the plate body, a plug hole is opened through the plate body, and a slot is opened at the end of the mounting plate away from the rotating shaft. When the mounting plate is fitted on the plate body, one end of the first plug rod passes through the plug hole and is embedded in the slot, and the end of the first plug rod is threadedly connected to the slot.

[0012] By adopting the above technical solution, when the mounting plate is rotated to abut against the plate body during use, the end of the first insertion rod can be passed through the insertion hole and then threadedly connected in the slot, thereby realizing the clamping and limiting of the mounting plate, which is simple and convenient to use.

[0013] Preferably, a fixing seat is fixedly connected to the frame, and a second limiting structure for limiting the position of the mounting plate after rotation is provided on the fixing seat.

[0014] By adopting the above technical solution, when the roller needs to be flipped during use, the mounting plate can be first rotated 180 degrees upward so that the mounting plate is located on one side of the plate body, thereby making the roller located on the upper side of the plate body, and then the mounting plate is limited by the second limiting structure to prevent the mounting plate from rotating downward, thereby realizing flipping of the roller. It is simple and convenient to use and there is no need to disassemble the roller.

[0015] Preferably, the fixing seat comprises a folding plate fixed on the frame body and a side plate fixedly connected to the folding plate, and the second limiting structure is arranged at an end of the side plate away from the folding plate.

[0016] By adopting the above technical solution, when in use, the second limiting structure is set at the end of the side plate away from the folding plate, thereby ensuring that when the mounting plate is rotated to the upper side of the plate body, the second limiting structure is set opposite the mounting plate, thereby ensuring that the second limiting structure effectively limits the mounting plate.

[0017] Preferably, the second limiting structure includes a second rod threadedly connected to the side panel, one end of the second rod is a hand-held end, and the other end is a plug-in end, the hand-held end of the second rod is located on one side of the side panel, and the plug-in end of the second rod is located on the other side of the side panel after passing through the side panel.

[0018] By adopting the above technical solution, when in use, the handheld end of the second plug rod is rotated to make the second plug rod threadedly connected to the side plate, and then the plug-in end can be abutted against the bottom wall of the mounting plate to achieve the limitation of the mounting plate, which is simple and convenient to use.

[0019] Preferably, the plug-in end of the second plug rod is provided with a spring head.

[0020] By adopting the above technical solution, a spring head is set during use. During the process of rotating the mounting plate upward, there is no need to rotate the second plug rod. The spring head can be squeezed by the mounting plate. When the mounting plate is rotated to 180 degrees, the spring head elastically returns to its original position and abuts against the bottom wall of the mounting plate, thereby limiting the mounting plate and making it more convenient to use.

[0021] Preferably, the mounting plate is provided with a guide inclined surface for guiding the extension and retraction of the spring head.

[0022] By adopting the above technical solution, a guide bevel is set during use. When the mounting plate is rotated upward, the guide bevel guides the extension and contraction direction of the spring head, so that the spring head is compressed, thereby facilitating the rotation of the mounting plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the frame needs to be moved during use, the roller is flipped to abut against the ground, and then the frame is pushed to make the roller roll, so as to realize the movement of the frame. When the inspection fixture on the frame needs to be inspected, the roller is simply flipped upward to the upper side of the plate body to avoid the height of the roller itself affecting the inspection structure in the height direction of the inspection fixture. Compared with the existing technology, there is no need to disassemble the roller, which is more convenient to use;

[0025] 2. During use, the first limiting structure is used to prevent the roller from flipping during rolling, which causes the frame to move unstably. The second limiting structure is used to abut and limit the flipped roller to prevent the roller from flipping downward and affecting the detection of the inspection fixture, which is more conducive to use;

[0026] 3. During use, the spring head and the guide bevel are used in conjunction. When the mounting plate is flipped upward, the spring head is guided by the guide bevel so that the spring head slowly moves away from the mounting plate under the squeezing of the mounting plate. When the mounting plate is rotated to above the spring head, the spring head is reset under the action of the compression force, so that the side wall of the spring head abuts against the bottom wall of the mounting plate, thereby limiting the mounting plate. When the mounting plate needs to be rotated downward, just press the spring head. It is simple and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

The plate body 31 is fixed to the bottom surface of the frame 1 by bolts, and the rotating shaft 32 is welded to one end of the plate body 31. A connecting block 33 is welded to one end of the mounting plate 4. The overall shape of the connecting block 33 is L-shaped, and one end of the connecting block 33 is hinged on the rotating shaft 32. When in use, the roller 2 can be flipped over to be away from the bottom surface by rotating the mounting plate 4 180 degrees, thereby avoiding affecting the accuracy of the detection result of the height direction of the inspection fixture.

[0038] Reference Figure 2 and Figure 3 In order to prevent the mounting plate 4 from rotating and causing the frame 1 to shake when the roller 2 rolls, a first limiting structure 5 is provided on the plate body 31. The first limiting structure 5 is used to prevent the mounting plate 4 from rotating. The first limiting structure 5 includes a first plug rod 51. The first plug rod 51 is located at the end of the plate body 31 away from the rotating shaft 32. The first plug rod 51 is vertically arranged with the plate body 31. A plug hole 52 is opened on the plate body 31 along the vertical direction, and a slot 53 is correspondingly opened on the mounting plate 4. When the mounting plate 4 is located below the plate body 31 during use, the mounting plate 4 can be limited by passing the bottom end of the first plug rod 51 through the plug hole 52 and then threadedly connected to the slot 53. The use is simple and convenient.

[0039] Reference Figure 2 and Figure 4 A cushion block 9 is welded on the frame 1, and a fixing seat 6 is arranged on the cushion block 9. The fixing seat 6 includes an L-shaped folding plate 61 and a triangular side plate 62. One end of the folding plate 61 is fixed to the cushion block 9 by bolts, and the side plate 62 is welded to the other end of the folding plate 61. A second limiting structure 7 is arranged at the end of the side plate 62 away from the folding plate 61.

[0040] Reference Figure 4 and Figure 5The second limiting structure 7 includes a second plug rod 71, one end of the second plug rod 71 is a hand-held end 711, and the other end is a plug-in end 712. The second plug rod 71 is threadedly connected to the side plate 62, and the hand-held end 711 of the second plug rod 71 abuts against one side of the side plate 62, and the plug-in end 712 of the second plug rod 71 passes through the side plate 62 and is located on the other side of the side plate 62.

[0041] Reference Figure 4 and Figure 5 When in use, when it is necessary to flip the roller 2 to leave the ground, the mounting plate 4 is rotated upward to more than 180 degrees, so that the roller 2 is rotated to be located above the side of the mounting plate 4. At this time, the staff then screws the handheld end 711 of the second plug rod 71 to move the second plug rod 71 toward the mounting plate 4 until the plug-in end 712 of the second plug rod 71 is located directly below the mounting plate 4. Thereafter, the mounting plate 4 is rotated downward under the action of gravity. When the bottom wall of the mounting plate 4 is in contact with the side wall of the plug-in end 712 of the second plug rod 71, the mounting plate 4 can be limited by the second plug rod 71, so as to achieve the positioning of the rotated roller 2 to the state of being off the ground, which is simple and convenient to use.

[0042] Reference Figure 4 and Figure 6 In order to facilitate the use of the second plug rod 71, a spring head 72 is provided at the plug-in end 712 of the second plug rod 71. The spring head 72 consists of a plug column 721 and a spring 722. One end of the spring 722 is fixedly connected to the second plug rod 71, and the other end is fixedly connected to the plug column 721. One end of the plug column 721 slides on the second plug rod 71, and the other end extends out of the second plug rod 71. A hemispherical head is integrally formed at the end of the plug column 721 away from the second plug rod 71, and a guide inclined surface 8 is correspondingly formed on the mounting plate 4.

[0044] The implementation principle of the embodiment of the present application is as follows: when in use, in the initial state, the roller 2 abuts against the ground, and the first plug rod 51 is inserted into the slot 53 to limit the mounting plate 4, thereby ensuring the stability of the roller 2 installation. Thereafter, the inspection tool is installed on the frame 1, and the frame 1 is pushed to make the roller 2 roll, so that the inspection tool can be moved to the inspection position of the three-dimensional coordinate inspection machine. Then, the staff screws the first plug rod 51 out of the slot 53 and rotates the mounting plate 4 upward to make the roller 2 flip over to the top of the mounting plate 4. At this time, the side wall of the plug connector of the second plug rod 71 abuts against the bottom wall of the mounting plate 4, thereby limiting the mounting plate 4, so as to realize the roller 2 flipping to a state of being off the ground, thereby avoiding the height of the roller 2 affecting the accuracy of the inspection result when the inspection tool is subjected to size inspection. The overall use is simple and convenient, and compared with the method of disassembling the roller 2 in the prior art, it is more time-saving and labor-saving.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
