Description

Technical Field

[0001] This utility model relates to the field of positioning tooling, specifically a positioning and guiding device. Background Technology

[0002] In industrial fields such as machining, assembly, and testing, precise positioning of ring-shaped workpieces (such as bearing rings, flanges, and seals) is a crucial step in ensuring product quality and production efficiency. Due to the characteristics of ring-shaped workpieces, such as being hollow, thin-walled, and having diverse dimensions, traditional positioning methods often suffer from poor adaptability and low positioning accuracy.

[0003] Currently, most positioning devices for ring-shaped workpieces use fixed-size positioning fixtures. Special tooling needs to be customized according to the outer diameter, inner diameter, and width of the ring-shaped workpiece. When the workpiece specifications change, the fixtures need to be changed frequently, which not only increases equipment costs but also leads to low production efficiency. Some adjustable positioning devices have complex structures and are adjusted through hydraulic or electric drive methods, but they have problems such as cumbersome operation and high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning and guiding device to solve the problems of complex structure and cumbersome operation of conventional ring workpiece positioning devices mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning and guiding device, comprising a positioning plate and a pad, wherein a first screw is fixedly installed on the top of the positioning plate through the pad, and a swing arm composed of a second screw, a connecting plate and a pulley is rotatably sleeved on the first screw, and a pressure plate is detachably installed between the pair of swing arms and the first screw, and the angle of the pair of swing arms is adjusted by the pressure plate to adapt to rings of different widths.

[0006] Preferably, a support block is fixedly installed on the top of the positioning plate, and the side wall of the support block is provided with a plurality of positioning grooves.

[0007] Preferably, the pressure plate is a T-shaped mechanism, and the pressure plate is provided with sliding holes for accommodating the first screw and the second screw.

[0008] Preferably, one end of the connecting plate is sleeved on the first screw, and the other end is rotatably sleeved with a pulley via the second screw.

[0009] Preferably, a plurality of nuts are screwed onto the first screw and the second screw respectively.

[0010] Preferably, the corners of the support blocks are rounded for a smooth transition.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a first screw, a connecting plate, a second screw, a pulley, and a pressure plate to form a swing arm. The connecting plate, the second screw, and the pulley are assembled to form a swing arm. The included angle of the swing arm can be adjusted according to the width of the annular component, so that the first screw and the pulley are tightly attached to the outer and inner walls of the workpiece, respectively. With the longitudinal pressing of the pressure plate, a multi-directional constraint is formed, achieving precise positioning. The structure is simple, the operation is convenient, and it has strong practicality and applicability. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: a positioning and guiding device, including a positioning plate 1 and a pad 2. A support block 6 is fixedly installed on the top of the positioning plate 1. The side wall of the support block 6 is provided with a number of positioning grooves. The positioning grooves are designed to provide support for docking workpieces. Different shaped positioning grooves can accommodate workpieces of different shapes. The corners of the support block 6 are rounded to make them smooth. The advantage of this design is that it avoids sharp corners from scratching the skin. The top of the positioning plate 1 is fixedly mounted with a first screw 3 via a pad 2. The bottom of the first screw 3 is threadedly connected to the pad 2. A swing arm, consisting of a second screw 4, a connecting plate 7, and a pulley 8, is rotatably sleeved on the first screw 3. One end of the connecting plate 7 is sleeved on the first screw 3, and the other end is rotatably sleeved on the pulley 8 via the second screw 4. A pressure plate 5 is detachably mounted between the pair of swing arms and the first screw 3. The pressure plate 5 is a T-shaped mechanism and has sliding holes for accommodating the first screw 3 and the second screw 4. When the angle between the pair of swing arms changes, the pair of second screws 4 move relative to each other in the sliding holes for adjustment. Several nuts are screwed onto the first screw 3 and the second screw 4 respectively. The angle between the pair of swing arms is adjusted by the pressure plate 5 to accommodate rings of different widths and thicknesses.

[0020] By removing the pressure plate 5 and placing the annular workpiece to be positioned above a pair of connecting plates 7, and then adjusting the included angle of a pair of swing arms according to the width of the annular component, the outer wall of the annular component is in contact with the first screw 3 and the inner wall is in contact with the pulley 8. Then, the pressure plate 5 is fitted onto the first screw 3 and a pair of second screws 4, and the nut is rotated to lock the pressure plate 5 onto the upper surface of the workpiece to complete the positioning.

[0021] This application uses a combination of a first screw 3, a connecting plate 7, a second screw 4, a pulley 8, and a pressure plate 5. The connecting plate 7, the second screw 4, and the pulley 8 are assembled to form a swing arm. The included angle of the swing arm can be adjusted according to the width of the annular component, so that the first screw 3 and the pulley 8 are tightly fitted to the outer and inner walls of the workpiece, respectively. With the longitudinal pressing of the pressure plate 5, a multi-directional constraint is formed, achieving precise positioning. The structure is simple, the operation is convenient, and it has strong practicality and applicability.
