Abstract
Description
Technical Field
[0001] This utility model relates to the field of rocker arm center distance detection technology, and more specifically, to a workpiece for rocker arm center distance detection. Background Technology
[0002] Special bearings generally consist of a rocker arm and an inner ring, with the inner ring capable of rotating flexibly.
[0003] However, there are still some shortcomings in the center distance detection of this special bearing. It cannot simulate actual working conditions, and the center distance detection is relatively complex. Actual measurement cannot be directly performed, which cannot meet the requirements of high-quality production. Therefore, using a certain type of special bearing center distance measuring fixture can greatly improve production efficiency and detection accuracy, and meet assembly requirements.
[0004] Therefore, it is very necessary to invent a tooling based on the principle of designing a center distance measuring tooling for a certain type of special bearing that simulates assembly requirements under actual working conditions. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a workpiece for detecting the center distance of a rocker arm, which has the advantage of being able to measure the center distance of a certain type of special bearing.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a workpiece for detecting the center distance of a rocker arm, comprising a measuring fixture, a detection component disposed on the outer side of the measuring fixture, the detection component comprising a first inner hole opened inside the measuring fixture, a second inner hole fixedly connected inside the measuring fixture, a first mandrel slidably connected inside the first inner hole, and a second mandrel slidably connected inside the second inner hole.
[0007] As a preferred technical solution of this utility model, an installation component is provided on the outside of the measuring fixture. The installation component includes a shaped hole mandrel fixedly connected to the top of the measuring fixture. A special bearing is slidably connected to the outside of the shaped hole mandrel. The special bearing has a shaped hole inside, and the shaped hole is slidably connected to the outside of the shaped hole mandrel.
[0008] As a preferred embodiment of this utility model, the special bearing is provided with an auxiliary component, which includes a detection hole opened inside the special bearing, and the detection hole is slidably connected to a first mandrel and a second mandrel respectively.
[0009] As a preferred embodiment of this utility model, the measuring fixture is configured in a Z-shape, and the two ends of the measuring fixture are not parallel.
[0010] As a preferred embodiment of this utility model, the special bearing is configured in a Z-shape, and the two ends of the special bearing are not parallel.
[0011] As a preferred embodiment of this utility model, the two ends of the measuring fixture are respectively arranged parallel to the two ends of the special bearing.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by measuring the fit between the first inner hole and the second inner hole inside the tooling, allows the first mandrel and the second mandrel to pass through the first inner hole and the second inner hole, thereby allowing the first mandrel and the second mandrel to enter the interior of the special bearing. This allows for the detection of the center distance of the special bearing, and thus allows for the detection of the center distance between the semi-finished and finished products of the special bearing.
[0014] 2. This utility model detects the center distance of special bearings by checking the degree of sliding between the first and second mandrels and the test hole. When the first and second mandrels can smoothly enter the test hole, it indicates that the center distance of the special bearing is qualified. If there is jamming or they cannot enter, it indicates that they are unqualified. This simple method can detect the center distance of special bearings, thereby reducing the difficulty of detection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6 As shown, this utility model provides a workpiece for detecting the center distance of a rocker arm, including a measuring fixture 1. A detection component is provided on the outside of the measuring fixture 1. The detection component includes a first inner hole 6 opened inside the measuring fixture 1, a second inner hole 7 fixedly connected inside the measuring fixture 1, a first mandrel 8 slidably connected inside the first inner hole 6, and a second mandrel 9 slidably connected inside the second inner hole 7.
[0024] By measuring the fit between the first inner hole 6 and the second inner hole 7 inside the tooling 1, the first mandrel 8 and the second mandrel 9 can pass through the first inner hole 6 and the second inner hole 7, thereby allowing the first mandrel 8 and the second mandrel 9 to enter the special bearing 3. This allows the center distance of the special bearing 3 to be detected, and the center distance of the semi-finished and finished products of the special bearing 3 to be detected.
[0025] When the center distance is tested, the degree of sliding between the first spindle 8 and the second spindle 9 and the test hole 5 is used for testing. When the first spindle 8 and the second spindle 9 can smoothly enter the test hole 5, it indicates that the center distance of the special bearing 3 is qualified. If there is jamming or it cannot enter, it indicates that it is unqualified.
[0026] The measuring fixture 1 is provided with an installation component on its outer side. The installation component includes a shaped hole mandrel 2 fixedly connected to the top of the measuring fixture 1. A special bearing 3 is slidably connected to the outer side of the shaped hole mandrel 2. The special bearing 3 has a shaped hole 4 inside. The shaped hole 4 is slidably connected to the outer side of the shaped hole mandrel 2.
[0027] The position of the special bearing 3 is fixed by fitting the irregular hole 4 onto the outside of the irregular hole mandrel 2.
[0028] The special bearing 3 has an auxiliary component inside, which includes a detection hole 5 inside the special bearing 3. The detection hole 5 is slidably connected to the first spindle 8 and the second spindle 9 respectively.
[0029] The first spindle 8 and the second spindle 9 are slidably connected to the inside of the detection hole 5 to detect the detection hole 5. The smooth passage of the first spindle 8 and the second spindle 9 is used to determine whether the center distance of the special bearing 3 is qualified.
[0030] Among them, the measuring fixture 1 is set in a Z-shape, and the two ends of the measuring fixture 1 are not parallel.
[0031] By setting the measuring fixture 1 to a Z-shape, it can be used with the special bearing 3.
[0032] Among them, the special bearing 3 is set in a Z-shape, and the two ends of the special bearing 3 are not parallel.
[0033] By setting the special bearing 3 in a Z-shape, the special bearing 3 can be inspected by measuring fixture 1.
[0034] The measuring fixture 1 is set parallel to the two ends of the special bearing 3 at both ends.
[0035] By measuring the fact that the shapes of tooling 1 and special bearing 3 are basically the same, special bearing 3 can be inspected.
[0036] The working principle and usage process of this utility model: By measuring the fit between the first inner hole 6 and the second inner hole 7 inside the tooling 1, the first mandrel 8 and the second mandrel 9 can pass through the first inner hole 6 and the second inner hole 7, so that the first mandrel 8 and the second mandrel 9 can enter the special bearing 3. In this way, the center distance of the special bearing 3 can be detected, and the center distance of the semi-finished and finished products of the special bearing 3 can be detected.
[0037] When the center distance is tested, the degree of sliding between the first spindle 8 and the second spindle 9 and the test hole 5 is used for testing. When the first spindle 8 and the second spindle 9 can smoothly enter the test hole 5, it indicates that the center distance of the special bearing 3 is qualified. If there is jamming or it cannot enter, it indicates that it is unqualified.
