Description

Technical Field

[0001] This utility model belongs to the field of workpiece inspection, specifically relating to a rapid inspection tool that uses levers to measure dimensions. Background Technology

[0002] Inspection tools are simple tools used by industrial manufacturing enterprises to control various dimensions of products (such as hole diameter, spatial dimensions, etc.), improve production efficiency and control quality. They are suitable for mass-produced products, such as automotive parts, to replace professional measuring tools, such as smooth plug gauges, thread plug gauges, and outside diameter calipers.

[0003] In the automotive manufacturing industry, it is necessary to inspect the outer diameter of large workpieces. Existing inspection fixtures need to be adapted to corresponding propulsion mechanisms. Due to the large stroke, the main body of the device is large, resulting in a large space occupation. Due to the special nature of the workpieces, the inspection efficiency of existing inspection fixtures is low.

[0004] Therefore, we propose a rapid inspection tool that utilizes levers to measure dimensions. Utility Model Content

The probe passes through the protective plate. A buffer spring is provided between the protective plate and the slide rod.

[0012] This invention has the following advantages over the prior art: This utility model discloses a quick inspection tool for measuring dimensions using levers. In use, the workpiece is first positioned and fixed in the positioning assembly. The handle is rotated, which drives the rotating shaft to rotate. The rotating shaft drives the first connecting rod to rotate along the shaft. The first connecting rod and the second connecting rod are rotatably connected, thereby driving the second connecting rod to rotate. The second connecting rod drives the slide plate to slide on the slide rail. The use of a connecting rod structure achieves the same depth of advance, reduces the length of the drive assembly, reduces the area occupied, and improves practicality.

[0013] This utility model discloses a rapid inspection tool for measuring dimensions using levers. The drive assembly pushes the positioning block downwards, thereby pushing the probe along the workpiece into the pipe to be tested. During the stroke, the protective plate contacts the workpiece and compresses the buffer spring. When the probe moves to the point to be tested, the corresponding handle is rotated. The handle drives the push rod to rotate, allowing the locking block to pass through the slot in the locking plate, thereby pushing the handle. The handle pushes the push rod, and the push rod pushes the corresponding connecting rod three through the top push block.

At the same time as the reset, the buffer spring pushes the protective plate to slide along the slide bar, so that the probe is placed inside the protective plate, which can effectively protect the probe and improve the product's service life.

[0022] Furthermore, the output end of the dial indicator 15 is rotatably mounted with connecting rod 3 14, one end of which is fixedly mounted with probe 24. The side plate 21 is fixedly mounted on the side of the positioning block 13. There are two side plates 21, which are symmetrically arranged. The back plate 5 is fixedly mounted with a clamping plate 17 at the corresponding position of the side plate 21. A clamping groove is opened in the clamping plate 17, and a push rod 20 is slidably mounted in the groove. One end of the push rod 20 is fixedly mounted with a handle 19, and the other end of the push rod 20 is fixedly mounted with a push block 26. The push block 26 is in contact with the connecting rod 3 14. The side of the push rod 20 near the handle 19 is fixedly mounted with a clamping block 18.

During the stroke, the protective plate contacts the workpiece and compresses the buffer spring 23. When the probe 24 moves to the point to be tested... Rotating the corresponding grip 19 causes the push rod 20 to rotate, allowing the locking block 18 to pass through the slot in the locking plate 17, thereby pushing the grip 19. The grip 19 pushes the push rod 20, which in turn pushes the corresponding connecting rod 14 via the top push block 26. The connecting rod 14 drives the top probe 24 to measure the workpiece dimensions, which are displayed on the dial indicator 15. This simplifies the inspection process and effectively improves inspection efficiency. After the inspection is completed, the drive mechanism resets. Simultaneously, the buffer spring 23 pushes the protective plate to slide along the slide rod 22, so that the probe 24 is inside the protective plate, effectively protecting the probe 24 and improving the product's service life.
