[0002] In the current industrial manufacturing environment, the press is a sophisticated and versatile mechanical device with a wide range of applications and high production efficiency. It can cause metal to undergo plastic deformation and fracture by applying strong pressure. It is widely used in processes such as cutting, punching, blanking, bending, riveting and forming. With the gradual popularization of industrial intelligence, presses have begun to adopt the carriage method for automatic feeding. However, the precise positioning of the carriage is one of the key factors to ensure the accuracy and efficiency of the processing.

[0003] Traditional methods for precise positioning of trolleys mainly rely on precision machining technology. By accurately machining the components at each stage, the accuracy of the trolley during movement and parking is ensured. However, inaccurate positioning still occurs during actual installation. On-site workers often need to manually grind the positioning blocks, which not only increases the workload but may also introduce new errors, affecting positioning accuracy and processing efficiency. Therefore, the market urgently needs to develop a precise positioning structure for trolleys to help people solve existing problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 The present invention provides an embodiment of a trolley precision positioning structure adapted to a press, comprising a trolley 2, a press base 1 disposed below the trolley 2, positioning sleeves 3 symmetrically disposed on both sides inside the trolley 2, positioning holes 301 disposed inside the positioning sleeves 3, welding blocks 4 disposed on the lower sides of both sides of the positioning sleeves 3, and fixing screws 6 symmetrically disposed on both sides inside the trolley 2. The trolley 2, positioning sleeves 3 and welding blocks 4 are connected by fixing screws 6. A positioning block 5 is fixedly installed on the upper part of the press base 1 along the lower part of the positioning sleeves 3, and a positioning protrusion 501 is fixedly installed on the upper part of the positioning block 5. The positioning block 5 and the positioning protrusion 501 are configured as an integral structure, and the diameter of the positioning protrusion 501 matches the diameter of the positioning hole 301.

[0023] In use, when the carriage 2 moves onto the press base 1, a positioning block 5 is configured to ensure the accuracy of the position after the carriage 2 falls. The positioning block 5 is fixed to the press base 1 by fixing screws 6. After the carriage 2 falls, the positioning protrusion 501 of the positioning block 5 can be stably inserted into the positioning hole 301 of the positioning sleeve 3. After the position is determined, the welding block 4 is welded to the carriage 2. By setting up the connection between the welding block 4 and the positioning sleeve 3 in advance, the position of the welding block 4 can be adjusted on site according to the actual situation and directly welded. This effectively reduces the on-site grinding process for workers, improves the positioning accuracy, saves processing time and costs, and increases processing efficiency.

[0024] Please see Figure 4The trolley 2 has a top plate 7 fixedly installed inside. A positioning plug is provided on one side below the top plate 7. The positioning plug includes a positioning post 8 and a round head 9. The upper end of the positioning post 8 is fixedly connected to the top plate 7, and the round head 9 is fixedly installed below the positioning post 8. The press base 1 has a base plate 13 fixedly installed inside. A mounting platform 12 is provided on the top of the base plate 13. A support plug is installed on the top of the mounting platform 12. The support plug includes a positioning cylinder 10 and a guide cylinder 11. The lower end of the positioning cylinder 10 is fixedly connected to the mounting platform 12, and the guide cylinder 11 is fixedly installed on the top of the positioning cylinder 10. The inner diameter of the positioning cylinder 10 matches the outer diameter of the positioning post 8. The guide cylinder 11 is tapered to improve the fault tolerance rate and make the positioning post 8 stably inserted into the guide cylinder 11. During the process of the trolley 2 moving down and landing on the press base 1, the cooperation of the positioning plug and the support plug can prevent the trolley 2 from deviating in the downward direction.

[0025] The precise cooperation between the positioning pin 8, the positioning cylinder 10, and the guide cylinder 11 effectively prevents the directional deviation of the trolley 2 during the downward movement process, ensuring that the positioning protrusion 501 of the positioning block 5 can be accurately inserted into the positioning hole 301 of the positioning sleeve 3, thereby improving the reliability of the entire positioning structure.

[0026] Please see Figure 4 An electric cylinder 14 is fixedly installed below the base plate 13. The push rod end of the electric cylinder 14 slides through the base plate 13 and is fixedly connected to the mounting platform 12, so that the electric cylinder 14 can drive the bearing insert to move up and down. When the trolley 2 has not moved to the press base 1, the bearing insert is driven to retract into the press base 1 to prevent it from hindering the movement of the trolley 2. Then, when the trolley 2 moves to the press base 1 and is about to fall, the bearing insert is driven to move up to facilitate the engagement of the bearing insert with the positioning insert.

[0027] The flexible lifting and lowering of the support component is achieved, which can avoid hindering the movement of the trolley 2 when it is not in position, and can quickly cooperate with it when the trolley 2 is in position, thereby enhancing the automation of the entire positioning process and reducing the complexity of manual intervention.

[0028] Please see Figure 4 Stabilizing rods 15 are symmetrically fixed on both sides below the mounting platform 12. The lower end of the stabilizing rod 15 slides through the base plate 13. The setting of the stabilizing rod 15 increases the stability of the lifting and moving of the support component.

[0029] The stabilizer bar 15 provides additional stability support for the lifting and lowering movement of the support component, effectively preventing swaying or displacement that may occur during the lifting and lowering process, which helps to improve the stability and reliability of the positioning process.

[0030] Please see Figure 4Inside the press base 1, a platform 16 is fixedly installed along one side of the base plate 13. A laser rangefinder 17 is fixedly installed on the top of the platform 16, which facilitates the monitoring of the height and distance of the trolley 2 and helps to monitor and confirm the displacement of the trolley 2 during its descent.

[0031] It can monitor the height and distance of the trolley 2 in real time, providing operators with intuitive and accurate feedback information, which makes it easier for them to adjust and control the descent process of the trolley 2 in a timely manner. This not only improves the accuracy of positioning, but also enhances the safety and controllability of the entire positioning process.

[0032] Working principle: During use, when the trolley 2 moves above the press base 1, the positioning plug inside the trolley 2 cooperates with the bearing plug on the base to prevent the trolley 2 from deviating in direction during its descent. When the trolley 2 falls, the positioning sleeve 3 inside the trolley 2 matches the positioning block 5 on the base and the positioning protrusion 501 above it, ensuring that the positioning protrusion 501 can accurately insert into the positioning hole 301 after the trolley 2 falls. After the position is determined, the welding block 4 is welded to the trolley 2 to complete the setting of the positioning point structure of the trolley 2. This is conducive to the stable and accurate positioning of the trolley 2 for subsequent press loading, effectively reducing the on-site grinding process for workers, saving processing time and costs, and increasing processing efficiency.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
