Laser tracker target ball position marking tool

Technical Field

The utility model belongs to the technical field of the car, specific laser tracker target ball position marking instrument that says so.

Background

The laser tracker is very extensive at the in-process of setting up of welding the dress line body and uses, and its measuring range is big, and positioning accuracy is high, can help the constructor to realize the accurate positioning of tool equipment, saves the dress and transfers the time. Dozens of or even hundreds of devices are usually arranged on a welding production line, and each device needs to be arranged at a correct position according to a plane planning diagram, and the error is within 10 millimeters. At this time, the actual corresponding position of the equipment in the construction workshop needs to be found by using a laser tracker according to drawing coordinates, and then an operator marks the actual corresponding position. Generally, each device needs to be marked with 3-4 marks to be used as a reference during installation, and the task is heavy. The marking method adopted at present is to move the target ball to the coordinate position, an operator holds the target ball with one hand, draws the contour of the target ball base on the ground with the other hand, and then pastes a circular label on the contour. The greatest disadvantage of this method is the low efficiency, and the time for the operator to contour the target ball seat is more than 20% of the whole marking process. When the construction ground has the dust, the marker pen is difficult for the colour development, and the operator needs clear up the dust earlier, and efficiency reduces more. The construction period of the welding project is generally short, and shortening the scribing time is an effective way for improving the construction efficiency.

Detailed Description

Referring to fig. 1 and 2, the laser tracker target ball position marking tool comprises a target ball support block 2, a magnet 3, a support 4, a base plate 5, a pressing block 7 and a punch 8.

The target ball 1 of the laser tracker is positioned in a ball socket at the center of the target ball supporting block 2, and the two are tightly matched; the material of laser tracker target ball 1 is the steel, and 2 bottoms of target ball tray are inlayed and are had magnet 3, can hold laser tracker target ball 1, prevent its landing, and can not take place to shake in the low-speed motion.

The target ball bearing block 2 is fixed on the support 4 through a screw and a pin, and the pin can ensure enough connection precision. The holder 4 is fixed to the base plate 5 by screws. Two parallel-mounted cylindrical pins 6 are further mounted on the support 4, and the support 4 and the cylindrical pins 6 are in interference fit to prevent the cylindrical pins 6 from falling off. The upper ends of the two cylindrical pins 6 are in sliding fit with the pressing block 7, so that the pressing block 7 can move up and down along the cylindrical pins 6, and sufficient positioning accuracy can be guaranteed. The cylindrical pin 6 serves to guide the pressure piece 7. The pressing block 7 is of a hollow structure, and can not contact the target ball 1 of the laser tracker when moving downwards.

The bottom of the pressing block 7 is provided with a punch 8, and the structure of the punch can be divided into four sections: the first section, the second section, the third section and the fourth section are respectively arranged from top to bottom. The first section is precisely matched with the bottom of the pressing block 7 to realize self-positioning; the second section is a shaft shoulder, is attached to the pressing block 7 and is used for installing a fastening screw; the third section is a guide shaft and penetrates through the center of the spring 9; the fourth section is a conical structure and is used for punching a small pit on the cement ground. The top of the spring 9 is contacted with the shaft shoulder of the punch 8, and the bottom of the spring is pressed on the base plate 5 to support the punch 8 and the pressing block 7.

The base plate 5 is provided with a hole at a position concentric with the punch 8, and the hole is moderate in size, so that the punch can penetrate through the hole and the spring 9 can be prevented from falling off. In a natural state, the pressing block 7 and the punch 8 are lifted upwards under the action of the spring 9, and the tip of the punch 8 retracts into the hole of the substrate 5. When a worker finds the correct coordinate position of the target ball 1 of the laser tracker accurately through the laser tracker, the top of the pressing block 7 is knocked by a hammer, the pressing block 7 pushes the punching head 8 to move downwards, and the tip of the punching head 8 can be used for punching a pit on the ground to serve as a mark of the position of the target ball 1 of the laser tracker. After the external force is separated, the pressing block 7 rebounds upwards under the action of the spring 9 until the pressing block contacts the bottom of the target ball support block 2, and the punch 8 retracts.

Meanwhile, the pressing block 7 is contacted with the bottom of the target ball supporting block 2, so that the pressing block 7 cannot be separated. Three supporting screws 10 are arranged at the bottom of the base plate 5, so that the mechanism can be kept stable, the friction between the mechanism and the ground is reduced, and the movement is convenient.

As the cooperation between the laser tracker target ball 1 and the target ball supporting block 2, the target ball supporting block 2 and the support 4, the support 4 and the pressing block 7, and the pressing block 7 and the punch 8 on the tool all reach higher precision requirements, and the hole positions of each connecting link have enough relative position precision, the coaxiality of the punch 8 and the laser tracker target ball 1 center is finally ensured, namely the contact ratio of the marking point and the laser tracker target ball 1 position in the horizontal direction is ensured. An operator only needs to move the tool and the target ball 1 of the laser tracker to the correct position and knock the pressing block 7 to complete marking, so that time and labor are saved. Three evenly distributed support nails 10 arranged at the bottom of the tool support the base plate 5, so that the whole mechanism is stable, the friction between the mechanism and the ground is reduced, and a worker can slide the mechanism along the ground conveniently when using the mechanism. Meanwhile, the tool is also provided with a handle 12 which is convenient to hold. For lightening the structural weight, the base plate 5 and the handle 12 are made of aluminum alloy materials, and the connecting seat 11 is made of nylon, so that the mechanism is lighter and more flexible, and the use strength is not influenced.
