Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing and testing technology, and in particular to a gauge for measuring the distance from the main positioning hole of an automotive oil pan to the bracket mounting surface. Background Technology

[0002] The oil pan, a crucial component of an automotive engine, serves functions such as oil storage, lubrication, cooling, and sealing. During the machining of Yunnei oil pans, the distance between the locating hole and the bracket mounting surface requires extremely precise measurements (27±0.05, 277±0.05). Any deviation from this tolerance during machining will affect bracket installation, potentially leading to installation failure. Therefore, real-time measurement of this dimension is necessary during mass production of oil pans. However, coordinate measuring machines (CMMs) are costly and inefficient. To address this issue, we propose a gauge for measuring the distance between the main locating hole and the bracket mounting surface of automotive oil pans. Utility Model Content

[0004] The technical solution of this utility model is as follows: A gauge for measuring the distance from the main positioning hole of an automotive oil pan to the bracket mounting surface, comprising a gauge frame, with handles at both ends of the upper part of the gauge frame, multiple sets of pads symmetrically arranged on one side of the lower part of the gauge frame, two sets of positioning pins at the lower part of the gauge frame, two sets of connecting rods on the gauge frame, and a hand-tightening chuck on each connecting rod at the lower part of the gauge frame, with a dial indicator on the hand-tightening chuck and a washer on the dial indicator.

[0005] Preferably, the inspection fixture frame is provided with assembly holes at both ends, and the mounting end of the handrail is installed corresponding to the assembly hole.

[0006] Preferably, the inspection fixture frame has multiple sets of threaded holes on both sides, and the mounting end of the pad is installed corresponding to the threaded holes.

[0007] Preferably, the fixture frame has two sets of positioning holes, and the mounting end of the positioning pin is installed corresponding to the positioning hole.

[0008] Preferably, the fixture frame has two sets of through holes, the connecting rod is installed corresponding to the through holes, and a hexagonal threaded top rod is provided on the fixture frame near the connecting rod, the top of the hexagonal threaded top rod abutting against the connecting rod.

[0009] Preferably, the hand-tightening chuck is installed correspondingly to the outer ring of the connecting rod, the mounting end of the dial indicator is installed correspondingly to the hand-tightening chuck, and the mounting end of the washer is installed correspondingly to one side of the dial indicator.

[0010] Compared with the prior art, the present invention has the following beneficial technical effects:

[0011] This utility model has a simple overall structure, which greatly reduces the inspection cost and improves the inspection efficiency. After positioning the oil pan positioning hole, the dimensional deviation can be detected by observing the dial indicator value in the inspection tool. In this way, unqualified oil pans can be rejected in advance, and the processing parameters can be changed in time to avoid producing more unqualified products. Attached Figure Description

[0017] Example

[0018] like Figure 1-3As shown, this utility model proposes a gauge for measuring the distance from the main positioning hole of an automotive oil pan to the mounting surface of a bracket. It includes a gauge frame 1, with handles 2 at both ends of the gauge frame 1. Mounting holes are provided at both ends of the gauge frame 1. The mounting ends of the handles 2 are installed corresponding to the mounting holes and are fixedly connected to the gauge frame 1 through the mounting holes. The multiple handles 2 facilitate operator use of the device. Multiple sets of pads 3 are symmetrically arranged on one side of the lower part of the gauge frame 1. Gauges are provided on both sides of the gauge frame 1. Multiple sets of threaded holes are provided. The mounting end of the pad 3 is installed corresponding to the threaded hole 1, and the mounting end of the pad 3 is threadedly connected to the threaded hole 1. Multiple sets of symmetrically arranged locating pins 4 are tightly fitted to the inner cavity surface of the oil pan when in operation. Two sets of locating pins 4 are provided at the bottom of the fixture frame 1. Two sets of locating holes are provided on the fixture frame 1. The mounting end of the locating pin 4 is installed corresponding to the locating hole. The locating pin 4 is fixedly connected to the fixture frame 1 through the locating hole. The two sets of locating pins 4 are positioned and assembled with the locating groove on the oil pan. Two sets of connecting rods 5 are provided on the fixture frame 1. The fixture frame 1 has two sets of through holes. Connecting rods 5 are installed corresponding to these through holes, with the outer periphery of the connecting rods 5 tightly fitted to the inner wall of the through holes. The connecting rods 5 are slidably connected to the fixture frame 1. A hexagonal threaded push rod 9 is provided on the fixture frame 1 near the connecting rods 5, with the top end of the hexagonal threaded push rod 9 abutting against the connecting rods 5. A second threaded hole is provided on the fixture frame 1, and the mounting end of the hexagonal threaded push rod 9 is threadedly connected to the second threaded hole. The hexagonal threaded push rod 9 can position the connecting rods 5 assembled in the through holes. Each set of connecting rods 5 has a [missing information - likely a device or component] located below the fixture frame 1. A hand-tightening chuck 6 is installed correspondingly to the outer ring of the connecting rod 5. The hand-tightening chuck 6 can be tightened and fixed to the connecting rod 5. A dial indicator 7 is installed on the hand-tightening chuck 6. The mounting end of the dial indicator 7 is installed correspondingly to the hand-tightening chuck 6 and is fixedly connected to the outer side of the hand-tightening chuck 6. The dial indicator 7 is designed to facilitate the operator's timely inspection, thereby making it easier to measure the size of the oil pan. A washer 8 is installed on the dial indicator 7.
