Abstract
Description
Technical Field
[0001] This utility model belongs to the field of measurement and positioning technology, specifically relating to a positioning structure for a cylinder measuring machine. Background Technology
[0002] A cylinder measuring machine is used to measure data such as the wall thickness and roundness of a cylinder shell. On the measuring machine, the lower rollers drive the rotation, and then the probe measures the corresponding data.
[0003] Before measurement, the cylindrical shell needs to be positioned to ensure the accuracy of the measurement data. However, the cylindrical shell needs to be moved to the required position during positioning. Because the cylindrical shell is heavy, it is not only difficult to move it, but it is also easy to scratch the cylindrical shell, reducing the structural integrity of the cylindrical shell itself.
[0004] Therefore, a positioning structure for a cylinder measuring machine is proposed. Summary of the Invention
[0005] This utility model provides a positioning structure for a cylinder measuring machine, the purpose of which is to solve the problems mentioned above.
[0006] This utility model embodiment provides a positioning structure for a cylinder measuring machine, including a base; a support assembly and a lifting assembly disposed on the top of the base; wherein, the support assembly includes: two V-shaped brackets symmetrically disposed on the top of the base; a servo motor disposed on the outer wall of one side of one of the V-shaped brackets; an active support roller fixed to the output end of the servo motor; and a driven support roller rotatably positioned between the two V-shaped brackets near the active support roller; wherein, the lifting assembly includes: a cylinder disposed on the top of the base near the two V-shaped brackets; a lifting frame fixed to the output end of the cylinder; two side frames symmetrically disposed on the top of the lifting frame; a rotating roller rotatably positioned on the inner side wall of the side frame; a positioning assembly disposed on the top of the base; and a cylinder shell positioned above the side frames.
[0007] Furthermore, the positioning assembly includes: two three-phase motors symmetrically fixed to the outer wall of the base; lead screws fixed to the output ends of the two three-phase motors; a movable frame fixed to the nut seat on the lead screw by screws; a second side frame disposed on the inner side wall of the movable frame; and a second rotating roller rotating on the inner side wall of the second side frame.
[0008] Furthermore, the movable frame and the base are slidably connected by a slider and a groove;
[0009] By adopting the above technical solution, the stability of the mobile frame moving on the top of the base is ensured through sliding connection.
[0010] Furthermore, the second rotating roller and the first rotating roller rotate in the same direction;
[0011] By adopting the above technical solution, the cylinder shell can be pushed and displaced to achieve the purpose of positioning.
[0012] Furthermore, the active support roller is located to the side and below the driven support roller, and the active support roller is rotatably connected to another V-shaped bracket;
[0013] By adopting the above technical solution, the height difference between the active support roller and the driven support roller can ensure that the active support roller is in full contact with the cylinder shell, thereby increasing the friction between the cylinder shell and the active support roller. As a result, when the active support roller rotates, it can drive the cylinder shell to rotate.
[0014] Furthermore, the two side frames are arranged at a 150-degree angle to each other;
[0015] By adopting the above technical solution, the cylindrical shell can be supported and positioned.
[0016] The beneficial effects of this utility model are as follows:
[0017] This invention utilizes the lateral movement of the second rotating roller in the horizontal direction to push the cylindrical shell on the first rotating roller in the horizontal longitudinal direction. The rolling contact reduces the resistance when pushing the cylindrical shell, which not only facilitates the positioning of the cylindrical shell but also avoids wear on the outer surface of the cylindrical shell. The rotating roller can limit the movement of the cylindrical shell during rotation, preventing the cylindrical shell from deviating and affecting the measurement accuracy, and also ensuring smooth rotation of the cylindrical shell.
[0018] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] Reference Figure 1-4 This utility model embodiment proposes a positioning structure for a cylinder measuring machine, including a base 1. Two V-shaped brackets 21 from a support assembly 2 are symmetrically arranged on the top of the base 1. A servo motor 22 is fixedly connected to one side of the outer wall of one of the V-shaped brackets 21 by bolts. An active support roller 23 is fixedly connected to the output end of the servo motor 22 on one side. A driven support roller 24 is rotatably connected between the two V-shaped brackets 21 near the active support roller 23. The active support roller 23 is located below the driven support roller 24 and is rotatably connected to the other V-shaped bracket 21. Through the height difference between the active support roller 23 and the driven support roller 24, the active support roller 23 can fully contact the cylinder shell 5, increasing the friction between the cylinder shell 5 and the active support roller 23. Thus, when the active support roller 23 rotates, it can drive the cylinder shell 5 to rotate.
[0027] Two cylinders 31 from the lifting assembly 3 are symmetrically fixed to the top of the base 1 near the two V-shaped brackets 21 by bolts. The two cylinders 31 are fixedly connected to the lifting frame 32 through the output end on one side. Two side frames 33 are symmetrically arranged on the top of the lifting frame 32. The two side frames 33 are set at a 150-degree angle to each other, which can support and position the cylinder shell 5. Rotary rollers 34 are rotatably connected to the inner side walls of the two side frames 33. The cylinder shell 5 is supported above the rotary rollers 34.
[0028] Two three-phase motors 41 from the positioning assembly 4 are symmetrically arranged on the outer wall of the base 1. Each of the two three-phase motors 41 is fixedly connected to a lead screw 42 through its output end on one side. The nut seat on the lead screw 42 is fixedly connected to a movable frame 43 by screws. The movable frame 43 and the base 1 are slidably connected by a slider and a slide groove. The sliding connection ensures the stability of the movable frame 43 when moving on the top of the base 1. Two side frames 44 are symmetrically arranged on the inner wall of the movable frame 43. A rotating roller 45 is rotatably connected to the inner wall of the side frame 44. The rotating roller 45 and the rotating roller 34 rotate in the same direction, which can realize the displacement of the cylinder shell 5 to achieve the purpose of positioning.
[0029] The specific implementation method is as follows: Before measuring the cylindrical shell 5, the cylindrical shell 5 is first hoisted above the lifting frame 32. The cylindrical shell 5 is placed above the rotating rollers 34 on the two side frames 33. The rotating rollers 34 support the cylindrical shell 5. Due to the inclined setting of the rotating rollers 34, the cylindrical shell 5 is limited in the horizontal longitudinal direction.
[0030] Then, the control cylinder 31 drives the lifting frame 32 to move downward through its output end on one side, and the supported cylinder shell 5 moves downward synchronously. When the cylinder shell 5 is about to contact the active support roller 23 and the driven support roller 24, the lifting frame 32 stops moving downward.
[0031] Finally, the three-phase motor 41 is controlled to drive the lead screw 42 to rotate through its output end on one side. The moving frame 43 on the lead screw 42 moves linearly on the top of the base 1. The two moving frames 43 are controlled to move towards each other. The rotating roller 45 on the side frame 44 moves synchronously. The rotating roller 45 moves towards the cylinder shell 5. After the rotating roller 45 contacts the cylinder shell 5, it pushes the cylinder shell 5 to move on the rotating roller 34. Since there is rolling contact between the rotating roller 34 and the cylinder shell 5, the cylinder shell 5 can move smoothly when it is pushed, so that the cylinder shell 5 is pushed to a fixed position.
[0032] The lifting frame 32 continues to descend, and the active support roller 23 and the driven support roller 24 support the cylinder shell 5. The control servo motor 22 drives the active support roller 23 to rotate through its output end on one side. The friction between the active support roller 23 and the cylinder shell 5 causes the cylinder shell 5 to rotate. The wall thickness and roundness of the cylinder shell 5 are measured using measuring equipment.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
