Description

Technical Field

[0001] The utility model relates to the technical field of detecting the outer circle radius of a crankshaft balance weight, in particular to a gage for detecting the qualification degree of the outer circle radius of a crankshaft balance weight. Background Technique

[0002] In the processing of crankshafts, many crankshafts need to be installed with balance weights. However, whether the outer circle radius of the balance weight is within the normal error range needs to be detected by using detection tools. At present, the existing gages are all special gages. A gage of one model can only detect the outer circle radius of the crankshaft balance weight of one model. When detecting the outer circle radii of crankshaft balance weights of multiple models, different gages need to be replaced, the detection process is relatively complex, and different models of gages need to be manufactured, resulting in a high cost.

[0003] In the prior art, a gage for detecting the qualification degree of the outer circle radius of a crankshaft balance weight is mentioned in the patent number (CN201922425926.6). It includes a base, a fixed plate dial indicator, two support rods, two support blocks, a slide rail, a slider and a screw. The base is fixed with a fixed plate and a slide rail. Two support rods are fixed on the fixed plate. Two support blocks are respectively fixed at the upper ends of the two support rods. The slider is located on the slide rail and can slide relative to the slide rail. The dial indicator is fixed on the slider and the dial head points to the direction of the support rod. A second through hole is opened on the slider. The dial indicator is inserted into the second through hole. A second threaded hole is opened on the slider at the position of the second through hole. The screw is screwed into the second threaded hole to fix the dial indicator on the slider. In this way, the dial indicator can slide left and right, and at the same time, the distance from the dial indicator to the two support blocks can be adjusted according to the crankshaft model, so that the gage can detect the outer circle radii of crankshaft balance weights of multiple models.

[0004] In the prior art, a dial indicator is added, thus replacing the traditional collar-type detection with a rotary detection, effectively solving the problems that when detecting the outer circle radii of crankshaft balance weights of multiple models, different gages need to be replaced, the detection process is relatively complex, and different models of gages need to be manufactured, resulting in a high cost. However, when facing a crankshaft with a large weight, due to the lack of an auxiliary loading mechanism, a great deal of manpower and material resources will be wasted for the loading and clamping operation of the heavy crankshaft.

Detailed implementation manners

[0020] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] Please refer to Figures 1 to 3 , Figure 1 which is the structural schematic diagram of the whole of the present invention, Figure 2 which is the front view of the whole of the present invention, Figure 3 which is Figure 2 the sectional view of the A - A line structure of the present invention.

[0022] The utility model provides a checking tool for the qualification of the outer circle radius of a crankshaft balance weight, which comprises a support frame 101, a detection table 102, a positioning and detection assembly and an air pump type auxiliary feeding assembly. The air pump type auxiliary feeding assembly comprises a cylinder 111, a transmission pipe 112, a pneumatic column 113, a rotating block 109 and a feeding table 110. The positioning and detection assembly comprises a support block 108, a support plate 103, a rotating shaft 104, a positioning frame 107, a pointer 105 and an identification groove 106. Through the foregoing scheme, the problem that when facing a crankshaft with a large weight, due to the lack of an auxiliary feeding mechanism, a great deal of manpower and material resources will be wasted for the feeding and clamping operation of the heavy crankshaft can be solved. It can be understood that in the foregoing scheme, when detecting the outer circle radius of a crankshaft with a large weight, the staff will first transport the crankshaft to the feeding table 110, and then the cylinder 111 is started to convey high-pressure gas to the pneumatic column 113 by using the transmission pipe 112. Thus, the pneumatic column 113 will extend upward, and the feeding table 110 will be lifted. The feeding table 110 will rotate on the rotating block 109. When the pneumatic column 113 reaches the limit, the support block 108 and the feeding table 110 will cooperate to clamp the crankshaft. Since the rotation of the feeding table 110 mainly uses the cylinder 111 and the pneumatic column 113 for feeding, the manpower and material resources required for the original feeding will be reduced. After the feeding is completed, the staff will rotate the rotating shaft 104 to rotate the positioning frame 107 to the outer surface of the crankshaft. At this time, the data of the pointer 105 and the identification groove 106 are recorded, and then the crankshaft is rotated. When the rotation of the crankshaft is completed, the data of the pointer 105 and the identification groove 106 before and after the rotation are compared to determine whether the outer circle radius of the crankshaft is qualified. Thus, while retaining the original beneficial effects, the manpower and material resources required for feeding are effectively reduced (at most reduced to 40% of the original required manpower and material resources), and the problem that when facing a crankshaft with a large weight, due to the lack of an auxiliary feeding mechanism, a great deal of manpower and material resources will be wasted for the feeding and clamping operation of the heavy crankshaft is actively and effectively solved.

[0023] For this specific embodiment, the inspection table 102 is detachably connected to the support frame 101 and is located above the support frame 101. The positioning and inspection assembly is fixedly connected to the inspection table 102 and is located above the inspection table 102. The cylinder 111 is fixedly connected to the support frame 101 and is located above the support frame 101, and the cylinder 111 is arranged below the inspection table 102. The air pressure column 113 is fixedly connected to the support frame 101 and is located above the support frame 101, and the air pressure column 113 is arranged below the inspection table 102, and the air pressure column 113 is arranged on one side of the cylinder 111. One end of the air pressure column 113 away from the support frame 101 passes through the inspection table 102 and is arranged above the inspection table 102. One end of the transmission pipe 112 is detachably connected to the cylinder 111 and is located on one side of the cylinder 111. The other end of the transmission pipe 112 is detachably connected to the air pressure column 113 and is located on one side of the air pressure column 113. The cylinder 111 is a functional component that cooperates with the transmission pipe 112 to provide power to the air pressure column 113, and the transmission pipe 112 is arranged in a T-shaped pipe. The air pressure column 113 will effectively lift the loading table 110 to achieve the function of assisting in loading.

[0024] Among them, the rotating block 109 is fixedly connected to the inspection table 102 and is located at the center above the inspection table 102, and the rotating block 109 is perpendicular to the air pressure column 113. The rotating block 109 is an auxiliary functional component for assisting the loading table 110 in the loading operation.

[0025] Among them, one end of the loading table 110 is rotatably connected to the rotating block 109 and is located on the outer surface of the rotating block 109. The lower end of the loading table 110 is detachably connected to the air pressure column 113 and is located above the air pressure column 113.

[0026] Secondly, the support block 108 is fixedly connected to the inspection table 102 and is located above the inspection table 102, and the support block 108 is arranged on the side of the rotating block 109 away from the loading table 110. The support block 108 is a component for cooperating with the loading table 110 to clamp the crankshaft.

[0027] Among them, the support plate 103 is fixedly connected to the inspection table 102 and is located above the inspection table 102, and the support plate 103 is arranged on the side of the support block 108 away from the rotating block 109. The support plate 103 will be a structural component for placing the rotating shaft 104 and the positioning frame 107.

[0028] Meanwhile, the rotating shaft 104 is rotatably connected to the support plate 103 and is located above one side of the support plate 103. The rotating shaft 104 is an auxiliary functional component that facilitates the rotation of the positioning frame 107 to a specified position.

[0029] Wherein, the positioning frame 107 is detachably connected to the rotating shaft 104 and is located on the outer surface of the rotating shaft 104. The positioning frame 107 will be the main functional component for detection.

[0030] In addition, the pointer 105 is detachably connected to the support plate 103 and is located on one side of the support plate 103. And the pointer 105 is arranged above the rotating shaft 104. The identification groove 106 is fixedly connected to the rotating shaft 104 and is located inside the rotating shaft 104. And the identification groove 106 is arranged on the inner side of the rotating shaft 104 close to the support plate 103. The identification groove 106 will cooperate with the pointer 105 to more intuitively display the data of the outer circle radius of the crankshaft to the staff.

[0031] When using the present utility model to detect the outer circle radius of a relatively heavy crankshaft, the staff will first transport the crankshaft to the loading table 110, and then the cylinder 111 will start to convey high-pressure gas to the air pressure column 113 through the transmission pipe 112. Thus, the air pressure column 113 will extend upward, thereby lifting the loading table 110. The loading table 110 will rotate on the rotating block 109. When the air pressure column 113 reaches the limit, the support block 108 and the loading table 110 will cooperate to clamp the crankshaft. Since the rotation of the loading table 110 mainly uses the cylinder 111 and the air pressure column 113 for loading, the manpower and material resources required for the original loading will be reduced. After the loading is completed, the staff will rotate the rotating shaft 104 to rotate the positioning frame 107 to the outer surface of the crankshaft. At this time, the data of the pointer 105 and the identification groove 106 are recorded. Then the crankshaft is rotated. When the rotation of the crankshaft is completed, the data of the pointer 105 and the identification groove 106 before and after the rotation are compared. Thus, it is judged whether the outer circle radius of the crankshaft is qualified. Thus, while retaining the original beneficial effects, the manpower and material resources required for loading are effectively reduced, and the problem that when facing a relatively heavy crankshaft, due to the lack of an auxiliary loading mechanism, a great deal of manpower and material resources will be wasted for the loading and clamping operation is actively and effectively solved.

[0032] The above-disclosed is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of the rights of the present utility model. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
