Description

Technical Field

[0001] The utility model relates to the technical field of quality inspection technology, in particular to a detection and limiting device for cemented carbide blades. Background Technique

[0002] Cemented carbide blades are a kind of cutting tools widely used in various cutting processing fields, which are mainly composed of cemented carbide and matrix metal. Cemented carbide is a very hard material that can maintain stable cutting performance and wear resistance during high-speed cutting. The matrix metal plays a role in supporting the cemented carbide blade, making it have strong durability and toughness. Cemented carbide blades can be used to cut various materials such as metals, woods, plastics, etc., and are widely used in fields such as machining, woodworking, and construction. Cemented carbide blades need to be limited and fixed by a detection and limiting device and undergo a series of quality inspections.

[0003] After retrieval, the patent with the Chinese patent authorization number CN209013849U discloses a detection tool for cemented carbide blades, including a mounting plate. The left side of the upper end of the mounting plate is rotatably connected to a rotating shaft through a rolling bearing. One end of the rotating shaft is fixedly connected to a turntable. The center of the upper end of the turntable is vertically fixedly connected to a limiting rod. A strip-shaped groove is opened on the upper end of the turntable, and a fixing mechanism is arranged in the strip-shaped groove.

A T-shaped sliding groove is opened on the right side of the upper end of the mounting plate, and a T-shaped sliding block is slidably connected in the T-shaped sliding groove. The detection tool for cemented carbide blades in the above patent has the following deficiencies: 1. The device limits and fixes the cemented carbide blade through structures such as a second spring, a sleeve, and a connecting rod. However, when the turntable rotates, the second spring has its own deformation, so it is easy to produce a certain deformation during rotation, resulting in the deviation of the limiting position, thus affecting the detection of the center of gravity during the rotation of the cemented carbide blade and causing a certain error in the detection structure; 2. The device lacks a pressing structure and a thickness detection function. Summary of the Utility Model

This solves the problem in the prior art of lacking a pressing structure and a thickness detection function. BRIEF DESCRIPTION OF THE DRAWINGS

When the lifting conical block 17 rises, it squeezes the second T-shaped slider 20 to expand outwards, thereby driving the connecting column 21 to slide directionally in the turntable 6, and then driving the limiting block 22 to squeeze the central axis part of the cemented carbide blade body 27 to achieve extrusion limit fixation;

[0031] Pressing thickness detection component, arranged on the inner wall of the box body 1.

[0032] Refer to Figure 3 、 Figure 5 and Figure 6 The pressing thickness detection component includes a first hydraulic cylinder 13 fixedly connected to the inner wall of the box body 1.

The lifting tapered block 17 rises to squeeze the second T-shaped slider 20 to expand outward, thereby driving the connecting column 21 to slide directionally within the turntable 6, and then driving the limiting block 22 to squeeze the central axis part of the cemented carbide blade body 27 to achieve extrusion and limit fixation. After that, by starting the first hydraulic cylinder 13, the lifting rod 24 is driven to move, and the pressing plate 23 is driven by the lifting rod 24 to squeeze and fix the top of the cemented carbide blade body 27 to prevent the cemented carbide blade body 27 from deviating in angle during rotation.

The driving bevel gear 19 is driven to rotate by the driving rod 18, and then meshes with the driven bevel gear 16 to drive it to rotate, and then drives the lifting tapered block 17 to rotate. The sliding and limiting relationship between the lifting tapered block 17 and the turntable 6 can drive the turntable 6 to rotate, thereby realizing the detection of the rotation center. When the center of the cemented carbide blade body 27 is offset or the shape is irregular, it will touch the baffle 12 and drive the cross bar 10 to move, and the movement distance of the cross bar 10 is marked on the first indicating plate 11, and it can be visually observed whether it is qualified or not.
