Installation and maintenance - T6920 vertical ball ruler installation and improvement. Nanyang Explosion-proof Group Co., Ltd. (Henan 473011) Ding Changping Wang Xinlong ruler is installed on the side of the bed rail. See the installation structure.
The device has occurred three times since its use: the longitudinal ball scale 2 - end fastening device 2. the ball scale 3. the machine tool guide 4. the column slide 5. the column 6. the bracket 7. the sensor sensor 8. the impact frame (1) Increasing the specifications of the fastening bolts of the fastening device 1 to increase the connection strength.
An eight-a (removed spring) (every lm) bracket device is added below the ball scale 2, the structure of which is seen to support the sagging of the ball scale 2.
The impact frame 8 is mounted, and its installation position is shown by a two-dot chain line. For the structure, it is used to measure the sensor 7 when the bracket 7 passes the bracket.
When the sensor 7 is not passed through the bracket, the bracket always supports the ball scale 2, and when the bracket passes, the impact frame 8 under the sensor 7 knocks the bracket open, and after the slider 4 is removed, the action of the spring strikes S3. The undercarriage bracket is restored to the original support. 1. The connecting plate fastening device is pulled off, the ball scale 2 is pressed together, causing severe deformation, and the measuring sensor 7 is stuck on the ball scale 2, thereby being scrapped. Stop the equipment and stop production.
After deep research and analysis, we believe that the cause of the accident: the ball scale 2 is heavier, although it is tightened by the fastening devices at both ends, but there is no support in the middle of the distance of 9m, the drooping amplitude is still very large. When the column slide 4 drives the measuring sensor 7 to move quickly, it is too late to be stuck, and the ball scale 2 is pressed and deformed, and the measuring sensor 7 is damaged.
The bolts of the two ends of the ball scale 2 are small in size.
To this end, we have taken the following measures to improve: 2. Impact frame support position.
The improvement not only eliminates such accidents fundamentally, but also saves the bracket 1. Spring connecting plate 2. Bracket roller 4. Moving bracket 7. Tension spring * Nail angle steel A lot of maintenance costs.
Anti-theft nut and special wrench Shandong Dongying Dongying District Urban Construction Committee Li Tao Sun Jingxue Liu Lantang In order to solve the stolen problem of field equipment and instruments, we designed the outer cone anti-theft nut and special wrench.
The anti-theft anti-theft anti-theft cover body anti-theft nut 1 can be added with the anti-theft cover 2 to further improve the anti-theft performance and prevent the removal of general tools. The bottom of the cover 2 has three small holes for the purpose of removing sewage. Even if the burglar cover is sawed, the remaining conical nuts can be burglarproof.
The special wrench () adopts an inner tapered surface with a taper such as a nut, and distributes the three-column pin in an arbitrary manner on the tapered surface, and corresponds to the three holes on the tapered surface of the nut, and the three-column pin and the inner taper body have an interference fit, and the tail portion Soldering and using high-quality alloy steel, the axial dimension of the wrench should be increased accordingly. s
