Description

Technical Field

[0001] This application belongs to the field of nut inspection, and in particular relates to a nut inspection mechanism. Background Technology

[0002] A nut is a fastener with internal threads that mates with a bolt. It is a mechanical part with internal threads that mates with a screw to transmit motion or power. A nut is also called a bolt cap; it's a part that is screwed onto a bolt or screw to achieve a fastening effect, and it's an essential component in all manufacturing machinery. There are many types of nuts; the most common are those conforming to Chinese national standards (GB), British standards (British standards), American standards (American standards), and Japanese standards (JP). Nuts are classified by material into several main types, such as carbon steel, high-strength steel, stainless steel, and plastic-coated steel. Based on product attributes and corresponding national standards, they are classified as ordinary, non-standard, (old) national standard, new national standard, American standard, British standard, and German standard. Different sizes and thread counts result in different specifications. Currently, most nut inspection agencies rely on manual inspection, which is inefficient and affects processing efficiency.

[0003] The existing publication number CN218411639U discloses an automatic nut detection mechanism, including a mounting frame, a fixed frame, a first curved frame, a second curved frame, a fixed sleeve, a spring pin, a detector, and a nut workpiece; wherein, the fixed frame is provided on the top of the mounting frame, and the first curved frame and the second curved frame are provided on one side of the mounting frame. Fixed sleeves are provided on the fixed frame, the first curved frame, and the second curved frame, and spring pins are provided in the inner cavity of the fixed sleeves; its structure is reasonable, with fixed sleeves provided on the fixed frame, the first curved frame, and the second curved frame respectively, spring pins provided in the inner cavity of the fixed sleeves, and a detector provided at the bottom of the fixed sleeves.

[0004] Although the aforementioned testing agencies have high testing efficiency, they cannot conveniently and quickly inspect the assembly condition of nuts. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a nut inspection mechanism that can conveniently and quickly inspect the assembly status of nuts.

[0006] This application provides a nut inspection mechanism, including a base, a worktable, and further comprising:

[0007] The testing frame is mounted on the base;

[0008] A detection assembly, which is mounted on a detection frame;

[0009] The detection assembly includes an electric slide rail, a sliding block, a cylinder, and a detection component. The electric slide rail is mounted on the detection frame, the sliding block is mounted on the electric slide rail, the cylinder is mounted on the sliding block, and the detection component is mounted on the sliding block.

[0010] When it is necessary to inspect the assembly condition of the nuts inside a workpiece, the workpiece is placed on the worktable. The user then drives the electric slide rail until the inspection piece aligns with the nut to be inspected on the workpiece. After that, the cylinder output end is driven to push out, causing the inspection piece to cover the nut on the workpiece and inspect the assembly condition of the nut. After the inspection is completed, the cylinder output end is reset, and the sliding block moves on the electric slide rail until it is aligned with the next nut to be inspected, and then the assembly condition of the next nut is inspected. The cooperation between the electric slide rail and the sliding block can conveniently and quickly inspect the assembly condition of the nuts.

[0011] Furthermore, the detection element includes:

[0012] Support frame, which is installed at the cylinder output end;

[0013] A detection pin, which is mounted on a support frame;

[0014] The mounting cavity is disposed within the detection pin;

[0015] The sensor is installed inside the mounting cavity.

[0016] When the nut is tested using the required testing component, the cylinder output end drives the testing component to move down until the nut is inserted into the mounting cavity. At this time, the sensor in the mounting cavity can detect the assembly status of the nut. After the test is completed, the cylinder output end resets. The nut is precisely covered by the mounting cavity when it is being tested, which improves the detection accuracy of the sensor.

[0017] Furthermore, the support frame includes:

[0018] Mounting bracket, which is installed at the cylinder output end;

[0019] Mounting holes are provided on both the left and right sides of the mounting bracket;

[0020] An adjustment frame is mounted on a mounting hole, and a detection pin is connected and installed on the adjustment frame.

[0021] With the inspection pin installed on the adjustment bracket, the user can choose to install and fix the adjustment bracket in the mounting holes on the left or right side of the mounting bracket. At the same time, the user can also remove the adjustment bracket from the mounting bracket and install the adjustment bracket and inspection pin in other places to inspect the nut, which improves the applicability of the inspection pin for nut inspection.

[0022] Furthermore, the mounting holes are provided in a plurality of manner, and the adjustment bracket can be installed on any one of the mounting holes.

[0023] The mounting holes are provided in a plurality of manner, and the adjustment bracket can be installed on any of the mounting holes. This allows the user to adjust the position of the adjustment bracket on the mounting bracket by fixing the position of the nut.

[0024] Furthermore, a limit bolt hole is provided on the side of the detection pin, and a limit bolt body is provided in the limit bolt hole.

[0025] After the user places the sensor in the mounting cavity on the detection pin, the user can screw the limiting bolt into the limiting bolt hole until the limiting bolt abuts against the sensor to fix the sensor's position, preventing the sensor from coming out of the mounting cavity and improving the positional stability of the sensor during operation.

[0026] Furthermore, the base is provided with a sliding groove, the sliding groove is provided with a sliding block, and the sliding block is provided with a worktable.

[0027] The base is provided with a sliding groove, and the sliding block is slidably installed in the sliding groove. At this time, the user can adjust the position of the sliding block in the sliding groove to adjust the position of the worktable on the sliding block until the nut is aligned with the detection pin and the adjustment is stopped.

[0028] The beneficial effects of this application are:

[0029] 1. After the test piece is completed, the cylinder output end is reset, and the sliding block moves on the electric slide rail until it is aligned with the next nut to be tested. Then the assembly status of the next nut is tested. The cooperation between the electric slide rail and the sliding block can conveniently and quickly test the assembly status of the nut.

[0030] 2. The nut is precisely covered by the mounting cavity when being detected, which improves the detection accuracy of the sensor;

[0031] 3. At the same time, users can also remove the adjustment bracket from the mounting bracket and install the adjustment bracket together with the detection pin in other places to inspect the nut, which improves the applicability of the detection pin to nut inspection scenarios.
