A rapid measurement tool

Abstract

This utility model discloses a rapid measurement and inspection tool, which includes a base. Two slide rails are fixedly connected to the bottom of the base. Two clamping plates are slidably connected to the outside of the slide rails, and two racks are slidably connected to the inside of the clamping plates. Gears are meshed inside the racks. This structure fixes the mechanism at the top of the base in a designated position, ensuring stable contact between the measuring element and the workpiece. For example, the pressure of contact sensors is consistent, and the optical path of non-contact lasers is not offset, avoiding fluctuations in measurement data caused by micro-movements. When the bolt height detection slider is pushed, if it can pass through and stop, the bolt height after riveting is good; otherwise, if it cannot pass through or stop, the bolt height after riveting is unqualified. This not only significantly shortens the training cycle but also reduces reliance on skilled workers. Even with personnel turnover, replacements can be quickly made, preventing production line shutdowns due to a lack of skilled inspectors.

Description

Technical Field

[0001] This utility model relates to the field of measurement and inspection tools, and in particular to a rapid measurement and inspection tool. Background Technology

[0002] Rapid measurement and inspection fixtures are high-efficiency quality inspection tools designed for mass production scenarios. At their core, they transform complex dimensional and feature inspections into rapid operations and clear results through structured design and intuitive judgment logic. This enables rapid verification and precise interception of key quality attributes of workpieces. Essentially, they replace subjective human judgment with the rigid benchmark of the fixture and replace step-by-step measurement with integrated inspection, adapting to the core needs of production lines with fast cycle times, high output, and the requirement for 100% full inspection.

[0003] In existing technologies, fixtures are designed one-to-one according to the size, shape, and testing requirements of specific products. For example, when testing a certain automotive connector, the positioning groove of the fixture must perfectly match the shape of the connector, and the pin for testing the position of the hole must accurately correspond to the design coordinates to ensure that only workpieces that meet the tolerances can be fitted with the fixture. This avoids misjudgment from a structural perspective. However, some fixtures may shake or shift, causing the measuring probe contacts to be unable to stably align with the measuring features of the workpiece, such as hole diameter, step height, and contour dimensions. This results in fluctuations in the measurement data each time, and even systematic deviations. Utility Model Content

[0004] The purpose of this invention is to ensure stable contact between the measuring element and the workpiece, such as consistent pressure of contact sensors and no optical path deviation of non-contact lasers, to avoid fluctuations in measurement data caused by micro-motions. It provides a rapid measurement fixture that solves the problem that when the fixture shakes, its positioning pins, clamping mechanisms, measuring sensors and other components collide and rub against the workpiece or worktable, causing wear of the positioning reference and deformation of the sensor probe, which further deteriorates the measurement accuracy.

[0005] This utility model also provides a rapid measurement and inspection tool as described above, including a base, two slide rails fixedly connected to the bottom of the base, two clamping plates slidably connected to the outside of the slide rails, two racks slidably connected to the inside of the clamping plates, and gears meshing with the inside of the racks.

[0006] According to the present invention, a rapid measurement and inspection tool is provided, wherein a drive rod is fixedly connected inside the gear, and a motor is fixedly connected to the output end of the drive rod.

[0007] According to the present invention, a rapid measurement and inspection tool is provided, wherein a measuring body is fixedly connected to the top of the base, and a first planar positioning block is fixedly connected to the top of the measuring body.

[0008] According to the present invention, a rapid measurement and inspection tool is provided, wherein a positioning pin is fixedly connected inside the first planar positioning block, and a cylindrical gauge is provided inside the first planar positioning block.

[0009] According to the present invention, a rapid measurement and inspection tool is provided, wherein a detection pin is fixedly connected to the top of the first planar positioning block, and a slider is fixedly connected to the top of the inspection tool.

[0010] According to the present invention, a rapid measurement and inspection tool is provided, wherein the first planar positioning block is externally fixedly connected to a connecting rod.

[0011] According to the present invention, a rapid measurement and inspection tool is provided, wherein a second planar positioning block is fixedly connected to one end of the connecting rod.

[0012] According to the present invention, a rapid measurement and inspection tool is provided, wherein an indicator light is fixedly connected to the top of the base.

[0013] Beneficial effects:

[0014] 1. This technical solution provides a rapid measurement and inspection tool. Driven by a motor at the bottom of the base, a drive rod rotates a gear at the top. The gear moves an external rack, which in turn moves two side clamps on a slide rail, fixing the mechanism at the top of the base in a designated position. This ensures stable contact between the measuring element and the workpiece, such as consistent pressure from contact sensors and no optical path deviation in non-contact lasers, avoiding fluctuations in measurement data caused by micro-motions.

[0015] 2. If the product can be placed into the inspection fixture, the hole position measurement is good, and the overall length of 283.00 mm does not exceed the upper limit. If two green lights are lit, there is no missing nut after riveting. If only one light is lit or neither light is lit, there is a missing nut, and it is a defective product. Pushing the bolt height detection slider, if it can pass through and stop, the bolt height after riveting is good. Conversely, if it cannot pass through or stop, the bolt height after riveting is unqualified. This not only greatly shortens the training cycle but also reduces the reliance on skilled workers. Even if there is a turnover of personnel, replacements can be made quickly, avoiding production line shutdowns due to a lack of skilled inspectors. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-2 This utility model provides a rapid measurement and inspection tool, which includes a base 1. Two slide rails 11 are fixedly connected to the bottom of the base 1. Two clamping plates 12 are slidably connected to the outside of the slide rails 11. Two racks 13 are slidably connected to the inside of the clamping plates 12. Gears 14 are meshed inside the racks 13.

[0023] Specifically, the gear 14 drives the external rack 13 to move, thereby the rack 13 drives the clamps 12 on both sides to move on the slide rail 11, so that the mechanism on the top of the base 1 is fixed in the designated position.

[0024] A drive rod 15 is fixedly connected inside the gear 14, and a motor 16 is fixedly connected to the output end of the drive rod 15.

[0025] Specifically, the motor 16 drives the drive rod 15 to rotate the top gear 14.

[0026] The top of the base 1 is fixedly connected to the inspection unit 3, and the top of the inspection unit 3 is fixedly connected to the first plane positioning block 7.

[0027] The first plane positioning block 7 is internally fixedly connected with a positioning pin 6, and a cylindrical gauge 4 is opened inside the first plane positioning block 7.

[0028] Specifically, it is cylindrical in shape, with a diameter equal to the minimum limit size of the hole, and a qualified hole should be able to easily insert a plug gauge.

[0029] The top of the first planar positioning block 7 is fixedly connected to a detection pin 5, and the top of the detection block 3 is fixedly connected to a slider 8.

[0030] Specifically, when pushing the bolt height detection slider 8, if it can pass through and stop, the bolt height after riveting is good; otherwise, if it cannot pass through or stop, the bolt height after riveting is unqualified.

[0031] The first planar positioning block 7 is externally fixedly connected to a connecting rod 9.

[0032] One end of the connecting rod 9 is fixedly connected to a second planar positioning block 10.

[0033] An indicator light 2 is fixedly connected to the top of the base 1.

[0034] Specifically, if both green indicator lights are on, there are no missing nuts after riveting. If only one light is on or neither light is on, there are missing nuts, and the product is defective.

[0035] Working principle: Driven by motor 16 at the bottom of base 1, and in conjunction with drive rod 15, the top gear 14 rotates. Gear 14 drives external rack 13 to move, which in turn drives the clamping plates 12 on both sides to move on slide rail 11. This fixes the mechanism at the top of base 1 in a designated position, ensuring stable contact between the measuring element and the workpiece. For example, the pressure of contact sensors is consistent, and the optical path of non-contact lasers is not offset. This avoids fluctuations in measurement data caused by micro-movements. If the product can be placed into the inspection fixture, the hole position measurement is good. The overall length of 283.00 mm does not exceed the upper limit. If indicator light 2 shows two green lights, there are no missing nuts after riveting. If only one light is on or neither light is on, there are missing nuts, and it is an NG product. Push the bolt height detection slider 8. If it can pass through and stop, the bolt height after riveting is good. Otherwise, if it cannot pass through or stop, the bolt height after riveting is unqualified. This not only greatly shortens the training cycle, but also reduces the dependence on skilled workers. Even if there is a turnover of personnel, they can be quickly replaced, avoiding production line shutdowns due to a lack of skilled inspectors.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
