Description

Technical Field

[0001] The utility model relates to the field of aluminum bar processing, in particular to a positioning device for sawing aluminum bars. Background Art

[0002] During the flange production process, aluminum bars need to be cut into aluminum bars of a certain length. However, existing sawing machines lack positioning devices and can only determine the required cutting length of the aluminum bars by moving the cutting head. Manual measurement and marking are usually used to determine the cutting length. This method is not only inefficient but also has low precision, which can easily lead to cutting errors and affect product quality.

[0003] Therefore, in order to solve the above problems, a positioning device for aluminum bar sawing is specifically proposed. Utility Model Content

[0004] The utility model aims to solve the above problems and specifically designs a positioning device for aluminum bar sawing, which can respectively determine the cutting length through two laser rangefinders and correct the position of the cutting head again during subsequent cutting to prevent errors caused by multiple cutting.

[0005] To achieve the above-mentioned objectives, the utility model provides a positioning device for aluminum rod sawing, comprising: a sawing machine platform, a first slide rail, a second slide rail, a limit device and a positioning mechanism, the side of the sawing machine platform is fixedly connected to the first slide rail and the second slide rail, the length of the first slide rail is greater than the length of the second slide rail, the limit device is fixedly connected to the second slide rail, the positioning mechanism is fixedly connected to the first slide rail, and the positioning mechanism is provided with a first laser rangefinder that can measure the distance from the positioning mechanism to the limit device and a second laser rangefinder that can measure the distance from the positioning mechanism to the sawing machine cutting head.

[0006] In the above manner, the limit device is used to block the end of the aluminum rod, and the positioning mechanism moves to the position of the length of the aluminum rod to be cut. The first laser rangefinder measures the distance from the positioning mechanism to the limit device, which is the length to be cut. The second laser rangefinder measures the distance from the positioning mechanism to the cutting head. The limit device is on the right side of the positioning mechanism, and the cutting head is on the left side of the positioning mechanism. The value measured by the second laser rangefinder is the distance from the left side of the positioning mechanism to the cutting head. The final cutting length is the value measured by the first laser rangefinder plus the value measured by the second laser rangefinder. The cutting head will produce a slight displacement after cutting. Therefore, when cutting again, the value of the second laser rangefinder needs to be corrected. The cutting head moves and corrects according to the numerical deviation to make the cutting position accurate each time.

[0007] Furthermore, the limiting device includes a limiting baffle and a clamping device, the limiting baffle is fixedly connected to the slider of the first slide rail, and the clamping device is fixedly connected to the end of the limiting baffle and is located above the aluminum rod.

[0008] In the above manner, after the limit baffle presses against the end of the aluminum rod, the clamping device moves downward to tighten the aluminum rod from the top.

[0009] Furthermore, the positioning mechanism also includes a positioning cylinder and a movable chuck, the positioning cylinder is fixedly connected to the slider of the first slide rail, the first laser rangefinder is fixedly connected to the slider of the first slide rail and is located on the side of the cylinder away from the limiting device, the second laser rangefinder is installed at the end of the positioning cylinder, and the movable chuck is movably connected to the telescopic head of the positioning cylinder.

[0010] Furthermore, the limit baffle includes a limit rod and a receiving plate, the receiving plate and the limit rod are an integrally formed structure, the receiving plate is fixedly connected to the second slide rail and is located in the same straight line as the first laser rangefinder, the limit rod extends from the second slide rail, and the clamping device is installed on the limit rod.

[0011] Furthermore, the movable chuck includes: a guide groove, a guide block, a fixed plate and a rack portion. The movable chuck is an arc-shaped structure. The guide groove is opened on two side surfaces of the movable chuck. The guide block is slidably connected in the guide groove. The end of the guide block is fixedly connected to the telescopic head through the fixed plate. The rack portion is opened on the periphery of the movable chuck, and the rack portion is slidably connected to the telescopic head.

[0012] In the above manner, the positioning cylinder pushes out the movable chuck, and then the end of the telescopic head is connected to a gear through a motor, and the gear drives the rack part. The movable chuck rotates and moves under the limit of the guide groove and the guide block, and moves from the side of the aluminum rod to the upper part of the aluminum rod, thereby fixing the aluminum rod from the top.

[0013] Furthermore, the clamping device includes a cylinder and a chuck, the cylinder is fixedly connected to the limiting rod, the chuck is an arc-shaped structure, and the chuck is fixedly connected to the telescopic end of the cylinder.

[0014] In summary, the present invention has the following advantages and beneficial technical effects:

[0015] 1. The utility model provides a positioning device for aluminum bar sawing, which can calibrate the length of the cut aluminum bar and prevent inaccurate cutting caused by the position change of the cutting head after multiple cuts;
