Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile production, in particular to a device for quickly detecting the sawing length tolerance of an aluminum profile. Background Art

[0002] In the production of aluminum profiles, the length and tolerance of aluminum profiles after cutting to length are the most important inspection parameters in production. The tolerance of aluminum profiles of conventional sizes is controlled at about plus or minus 3-5mm. Aluminum profiles that are too short or too long will be scrapped. For aluminum profiles cut by a fixed-length sawing machine, quality inspectors need to conduct re-inspections. The common method is to use a tape measure to conduct random inspections on the cut profiles. The frequency of random inspections is carried out in accordance with the specifications. If strict requirements for aluminum profiles require high-frequency random inspections, quality inspectors will have to do a heavy job of random inspections, and the efficiency is low. They have to add more staff, which increases the production inspection cost. Summary of the invention

[0003] In view of the above problems, the utility model provides a device for quickly detecting the sawing length tolerance of aluminum profiles, which can verify and check the length and tolerance of aluminum profiles, and has the advantages of easy use and high measurement accuracy. Moreover, by expanding multiple active detection mechanisms, aluminum profiles of multiple fixed lengths can be achieved.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A device for quickly detecting the sawing length tolerance of an aluminum profile, wherein a reference positioning block is arranged at one end of a platform, and a plurality of tracks arranged perpendicularly to the aluminum profile are arranged at the other end of the platform. A slidable movable detection mechanism is arranged on the track, and the movable detection mechanism comprises a detection block, and a stepped plane is arranged on the side of the detection block close to the end of the aluminum profile.

[0006] The position of the detection block is pre-positioned through measurement, and the detection block slides upward from the bottom. If the end of the low step still interferes with the end of the aluminum profile, and the detection block cannot continue to move upward, the length tolerance of the aluminum profile exceeds the upper limit and is too long; if the end of the low step does not interfere with the end of the aluminum profile, and the inclined surface of the step interferes with the aluminum profile, the length tolerance of the aluminum profile meets the requirements; if the inclined surface of the step part of the detection block cannot touch the end of the aluminum profile, the length tolerance of the aluminum profile exceeds the lower limit and is too short.

[0007] The movable detection mechanism includes a slide seat, which slides on the track. The detection block is fixedly mounted on the upper end surface of the slide seat. The slide seat is provided with a threaded hole, through which a positioning screw is inserted. The lower end of the positioning screw can be tightened against the platform surface. The detection block is fixed to the slide seat by bolts. If the model or length of the aluminum profile is changed, the detection block can be replaced to adapt to the new length and tolerance.

[0008] The function of the positioning screw is that when the movable detection mechanism is not needed, the positioning screw is screwed down and tightened against the surface of the platform to fix the position of the movable detection mechanism.

[0009] A limit rod is arranged on one side of the lower end of the track. The function of the limit rod is to prevent the slide seat from excessively displacing downward and sliding out of the track.

[0010] The platform is provided with a backing plate, the side of which abuts against the side of the aluminum profile. The function of the backing plate is to place the aluminum profile on the platform completely perpendicular to the track.

[0011] The platform is provided with a plurality of pads, the thickness of which is greater than or equal to the height of the track. The pads are used to raise the height of the aluminum profile so that when the middle or rear movable detection mechanism is needed, it will not interfere with the track.

[0012] Advantages of utility models

[0013] 1. The utility model is specially used for measuring the length tolerance of batch aluminum profiles. It does not require tape measures and scale tools. It is easy and quick to operate and has high measurement accuracy.

[0014] 2. The utility model can use aluminum profiles of multiple sizes and tolerances at the same time, and can be adjusted to other sizes and tolerances after replacing the detection block.

[0015] 3. The utility model has extremely low technical requirements for operators, and any operator can start operation after simple training. BRIEF DESCRIPTION OF THE DRAWINGS
