Description

Technical Field

[0001] The utility model belongs to the technical field of lead correction of dental rods, and particularly relates to a general-purpose dental rod lead correction device. Background Art

[0002] The dental rod is a lead screw. The ball screw is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotational motion into linear motion, or convert torque into axial reciprocating force. At the same time, it has the characteristics of high precision, reversibility and high efficiency. Due to its very small frictional resistance, the ball screw is widely used in various industrial equipment and precision instruments. During the use process, due to operation errors, the ball screw will be bent to a certain extent, thus unable to guarantee its accuracy. Therefore, it is necessary to correct its position.

[0003] During the lead correction process of traditional ball screws, a master with relatively high experience is often required to judge the bent position, and then smoothly correct it by pressing down or other methods. Therefore, a large amount of time will be wasted in judging the bent position, affecting the lead correction efficiency. And during the lead correction process, since the lead screw is fixed, it is easy to deflect when subjected to external forces, so it is impossible to press down at the accurate position. To solve the above problems, there is an urgent need for a general-purpose dental rod lead correction device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that during the lead correction process of traditional ball screws, a master with relatively high experience is often required to judge the bent position, and then smoothly correct it by pressing down or other methods. Therefore, a large amount of time will be wasted in judging the bent position, affecting the lead correction efficiency. And during the lead correction process, since the lead screw is not fixed, it is easy to deflect when subjected to external forces, so it is impossible to press down at the accurate position. And a general-purpose dental rod lead correction device is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A general-purpose dental rod lead correction device, including a workbench, a mounting sleeve is fixedly connected to the top surface of the workbench, a first support seat is slidably connected inside the mounting sleeve, a guide rail is fixedly connected to one side of the first support seat, a dental rod is arranged on the top surface of the first support seat, both the first support seat and the guide rail are threadedly connected with threaded rods through the threaded holes opened at their bottom ends, a first bevel gear is fixedly connected to the outer wall of the threaded rod, a rotating rod is rotatably connected inside the workbench, a second bevel gear is fixedly connected to the outer wall of the rotating rod, the second bevel gear is meshed with the first bevel gear, a clamping assembly is arranged on the top surface of the guide rail, and a lead correction assembly is arranged on one side of the workbench.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, by arranging a dial indicator inside, the tooth rod is installed on the first support base and contacted with the detection end of the dial indicator. When the bent part of the tooth rod is detected, the hydraulic push rod is started. The output end of the hydraulic push rod drives the pressing block to move downward to contact the tooth rod so as to align it. Through this design, the synchronous movement of the dial indicator and the hydraulic push rod is realized, so that the hydraulic push rod can accurately move to directly above the bent part, so as to accurately align the bent part, thereby improving the alignment accuracy and quickly aligning the tooth rod to improve the alignment efficiency.

[0018] 2. In the present utility model, by arranging clamping blocks inside, the dental rod is placed on the first support base. The pressing rod is pulled upwards to drive the clamping blocks to move upwards and compress the second spring. The dental rod is placed at the top of the second support base, and the pressing rod is released, so that the second spring drives the clamping blocks to move downwards to clamp it. Through this design, when guiding the dental rod, the clamping blocks are used to fix it to prevent it from shifting under force during the guiding process, which affects the guiding effect. By fixing the dental rod, the guiding accuracy can be improved, thereby improving the efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
