Description

Technical Field

[0001] This utility model relates to a testing device, specifically a crankshaft deep hole position gauge. Background Technology

[0002] Some types of crankshafts have deep holes at the ends. The main functions of these deep holes are to optimize balance, achieve dynamic balance correction of the crankshaft, remove or add lubricant within the holes to counteract centrifugal force during rotation and prevent engine vibration, and to deliver lubricating oil to bearings, gears, and other components at the crankshaft ends. Some crankshafts also have sensor probes or signalers installed within the deep holes to provide information signals such as crankshaft speed and phase to the engine control system.

[0003] These types of crankshafts require inspection of the deep holes at their ends. The crankshaft needs to be placed horizontally, and a test bar needs to be inserted horizontally from one end to check whether the machining of the deep holes is qualified. Since there are many different models of these crankshafts, the existing inspection methods are not only inefficient, but also require the manufacture of a separate inspection tool for each model, resulting in a waste of production quality. Summary of the Invention

A width adjustment pad is detachably mounted on the crank support seat, and a height adjustment pad is detachably mounted on the shaft support seats. A detection rod is installed in the detection hole of the deep hole detection seat, and a quick-pressing device is provided on the base plate on one side of the central positioning groove.

[0006] The central positioning groove and central positioning protrusion enable rapid positioning and installation of crankshaft support seats and multiple shaft support seats, saving equipment installation and commissioning time and improving efficiency. By adjusting and replacing the width and height adjustment shims, crankshafts of similar shapes but different sizes can be inspected, eliminating the need to produce multiple batches of inspection fixtures for crankshafts of different sizes.

[0007] Furthermore, a central positioning groove is provided along the length of the base plate, with both ends of the central positioning groove extending to the two edges of the base plate.

[0008] Furthermore, the top surface of the shaft support seat is a V-groove structure, and a height adjustment pad is provided on each of the two inclined surfaces of the V-groove of the shaft support seat.

[0010] Furthermore, the crank support seat has a U-shaped groove structure, and the width adjustment pad is detachably and fixedly connected to both vertical side walls of the U-shaped groove of the crank support seat by bolts.

[0011] Furthermore, a positioning sleeve is fixedly provided inside the detection hole of the deep hole detection seat, and the detection rod is mounted on the positioning sleeve.

[0012] Furthermore, the positioning sleeve includes a positioning sleeve body and a positioning retaining ring. The positioning retaining ring is disposed at one end of the positioning sleeve body. The positioning sleeve body is inserted into the detection hole of the deep hole detection seat, and the positioning retaining ring is locked outside the detection hole of the deep hole detection seat.

[0013] Furthermore, the fast-pressing device includes a fast-pressing height adjusting seat, a fast-pressing support, a fast-pressing connecting rod, a fast-pressing rod, and a fast-pressing handle rod; the fast-pressing height adjusting seat is fixedly mounted on the base plate, the fast-pressing support is fixedly mounted on the fast-pressing height adjusting seat, one end of the fast-pressing rod is hinged to the fast-pressing support at the lower part and to the end of the fast-pressing handle rod at the upper part, and the two ends of the fast-pressing connecting rod are respectively hinged to the fast-pressing support and the fast-pressing handle rod.

[0014] Furthermore, the free end of the quick-pressing rod is a long annular pressure plate. The upper and lower ends of the annular pressure plate are respectively provided with an upper clamping plate and a lower clamping plate. A screw is provided through the upper clamping plate and the lower clamping plate. The lower end of the screw is threadedly connected to a pressure head, and the upper end is provided with a locking nut.

[0015] Furthermore, the fast-pressing device is located next to the nearest shaft support to the crank support.

[0016] The advantages of this utility model are: the crankshaft deep hole position gauge of this solution can be used for crankshafts of different sizes and of the same type by setting different width adjustment pads and height adjustment pads, so as to realize accurate and fast horizontal detection of deep holes on the end face of the crankshaft, and has strong applicability.
