Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and testing technology, and in particular to a crankshaft inner hole depth detection device. Background Technology

[0002] As a core component of an engine, the crankshaft typically contains deep boreholes for lubrication or weight reduction. The depth accuracy of these boreholes directly affects the crankshaft's dynamic balance and service life, therefore precise inspection is essential after machining. Currently, the inspection of crankshaft bore depth is a key aspect of quality control.

[0003] Existing crankshaft bore depth measuring devices typically use a dial indicator or digital depth gauge in conjunction with a reference platform for measurement. During operation, the crankshaft is placed on the platform with one of its journals as a reference. The measuring rod of the dial indicator or digital depth gauge is then inserted into the bore to be measured until it reaches the bottom. The depth data is obtained by reading the value on the dial or display screen.

[0004] However, in actual use, existing crankshaft inner hole depth detection devices are cumbersome and inefficient for crankshafts with multiple inner holes at different angles. Utility Model Content

[0021] This utility model provides a crankshaft inner bore depth detection device, comprising a detection platform 101, a rotatable mounting base, a placement base 102, a vertical sliding platform, an electric push rod 103, and a dial indicator 104. The rotatable mounting base includes a mounting base 105, a rotating assembly, and a rotating disk 106. The rotating assembly includes a first servo motor 107 and an output gear 108. The vertical sliding platform includes a vertical guide rail 109, a sliding seat 110, and a height adjustment assembly. The height adjustment assembly includes a second servo motor 111, a threaded rod 112, and a ball screw and nut pair 113. This solution solves the problem of cumbersome and inefficient detection processes for crankshafts with multiple inner bores at different angles in existing crankshaft inner bore depth detection devices during practical use. It is understood that the aforementioned solution can be used in the structure of a crankshaft inner bore depth detection device.

[0022] In this specific embodiment, the upper surface of the testing platform 101 is provided with the rotatable mounting base, and the top of the rotatable mounting base is provided with the placement base 102. The top of the placement base 102 is provided with the insertion hole 114, which is adapted to one end of the crankshaft to be tested. The upper surface of the testing platform 101 is also provided with the vertical sliding platform, which is located on one side of the rotatable mounting base. The output end of the vertical sliding platform is provided with the electric push rod 103, and the output end of the electric push rod 103 is provided with the dial indicator 104. The measuring rod of the dial indicator 104 faces the axis of the rotatable mounting base. Through the arrangement of the placement base 102 and the insertion hole 114... The system can clamp the crankshaft to be tested. Through the rotatable mounting base, the crankshaft can be rotated via the placement base 102, aligning the inner holes at different angles on the crankshaft with the measuring holes of the dial indicator 104. The vertical sliding platform allows for height adjustment of the dial indicator 104, enabling the detection of inner holes at different positions. The electric push rod 103 drives the dial indicator 104 to perform precise automatic feeding and bottom-out measurement. This structure allows for the detection of the depth of inner holes at different angles and positions on the crankshaft, eliminating the time and manpower wasted on repeatedly adjusting the crankshaft position and manual alignment, significantly improving detection efficiency and reducing the operator's workload.

[0023] The mounting base 105 is installed at the center of the upper surface of the testing platform 101. The top of the mounting base 105 is provided with the rotating disk 106. The upper surface of the rotating disk 106 is provided with the placement base 102. The rotating component is installed inside the mounting base 105. The output end of the rotating component is mechanically driven to the rotating disk 106. When the rotating component is started, the rotating disk 106 is driven to rotate at the top of the mounting base 105, thereby completing the rotation of the crankshaft to be tested through the placement base 102.

[0024] Secondly, the first servo motor 107 is installed at the inner bottom of the mounting base 105. The output end of the first servo motor 107 is provided with the output gear 108. The top end of the mounting base 105 is provided with a rotating bearing 115. The rotating disk 106 is provided with an embedded ring 116 on the side facing the mounting base 105. The embedded ring 116 is embedded inside the rotating bearing 115. The embedded ring 116 is provided with a transmission gear 117 inside. The output gear 108 meshes with the transmission gear 117. The number of teeth of the output gear 108 is less than the number of teeth of the transmission gear 117. When the first servo motor 107 is started, it drives the output gear 108 to rotate. Since the output gear 108 meshes with the transmission gear 117, it drives the rotating disk 106 to rotate on the mounting base 105. The rotating bearing 115 makes the rotation of the rotating disk 106 on the mounting base 105 smoother.

[0025] Meanwhile, the vertical guide rail 109 is installed on one side of the rotatable mounting base, and the sliding seat 110 is slidably disposed on the side of the vertical guide rail 109 facing the rotatable mounting base. The height adjustment component is installed on the vertical guide rail 109, and the output end of the height adjustment component is connected to the sliding seat 110. When the height adjustment component is activated, the sliding seat 110 is driven to slide on the vertical guide rail 109, thereby completing the height adjustment of the dial indicator 104.

[0026] In addition, the second servo motor 111 is installed at the top of the vertical guide rail 109. The output end of the second servo motor 111 is provided with the threaded rod 112. The threaded rod 112 is provided with the ball screw nut pair 113. The ball screw nut pair 113 is connected to the sliding seat 110. When the second servo motor 111 is started, the threaded rod 112 is driven to rotate, thereby driving the sliding seat 110 to slide on the vertical guide rail 109 through the ball screw nut pair 113.

[0027] When using the crankshaft inner hole depth detection device of this utility model, the crankshaft to be tested can be clamped by setting the placement base 102 and the insertion hole 114. The first servo motor 107 is started, driving the output gear 108 to rotate. Since the output gear 108 meshes with the transmission gear 117, it drives the rotating disk 106 to rotate on the mounting base 105. The placement base 102 drives the crankshaft to rotate, so that the inner holes at different angles on the crankshaft correspond to the measuring holes of the dial indicator 104. The second servo motor 111 is started, driving the screw... The rotating pin 112 causes the sliding seat 110 to slide on the vertical guide rail 109 via the ball screw nut pair 113, thereby adjusting the height of the dial indicator 104 to complete the detection of the inner hole at different positions. The electric push rod 103 drives the dial indicator 104 to complete precise automatic feeding and bottom-out measurement. With the above structure, the depth of the inner hole at different positions and angles on the crankshaft can be detected, eliminating the time and manpower spent on repeatedly adjusting the crankshaft position and manual alignment, significantly improving detection efficiency and reducing the labor intensity of the operator.
