A positioning mechanism for a door hinge tooling trolley

Abstract

This utility model discloses a positioning mechanism for a door hinge tooling trolley, including a trolley with a fixed plate fixedly connected to its top. A controller is fixedly connected to one side of the fixed plate, and the bottom of the controller is fixedly connected to the top of the trolley. In this solution, the door panel is clamped and fixed by an electric push rod and a motor, and the length of the door panel is measured by a laser rangefinder and fed back to the controller. The hinge is placed in the designated position for installation by a second motor and a cylinder. Compared with manual measurement and positioning, this reduces measurement errors, improves positioning accuracy, ensures accurate hinge installation and normal use of the door panel, and reduces time consumption, ensuring the efficiency of hinge installation. The connecting block drives the pawl to engage with the ratchet, rotates the limiting block, and engages it with the slot on the top of the fixed block to complete the limiting. This effectively prevents positioning measurement errors caused by device vibration or the rotation of the bidirectional screw when the motor is de-energized, further ensuring the accuracy of hinge installation.

Description

Technical Field

[0001] This utility model relates to the field of door hinge tooling technology, and more specifically, to a positioning mechanism for a door hinge tooling trolley. Background Technology

[0002] Door hinge fixture trolleys are key equipment in the door and window manufacturing industry. By integrating mechanical clamping, positioning and adjustment functions, they enable efficient and precise docking of door panels and hinges, meet the requirements for rapid switching between different door specifications and types, and provide a basic guarantee for mass standardized production.

[0003] However, it still has some drawbacks in actual use. For example, the traditional process uses a manual positioning method, where the operator needs to measure the hinge installation position with a tape measure, manually mark the lines, and then drill holes for installation. This method is not very accurate, and the manual measurement error is large, which can cause the hinge axis to shift and easily lead to abnormal noise from the door panel. Manual measurement requires comparing multiple data, which is time-consuming and delays the door hinge installation progress. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a positioning mechanism for a door hinge tooling trolley to solve the problems of large errors and long time consumption in manual positioning in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a positioning mechanism for a door hinge tooling trolley, including a trolley, a fixing plate fixedly connected to the top of the trolley, a controller fixedly connected to one side of the fixing plate, and the bottom of the controller fixedly connected to the top of the trolley. The positioning mechanism for the door hinge tooling trolley also includes...

[0006] Mounting base, the mounting base is fixedly connected to one side of the trolley, and an electric push rod is fixedly connected to the top of the mounting base;

[0007] A push plate is fixedly connected to the output end of an electric push rod. The bottom of the push plate is slidably connected to the top of the trolley. A column is fixedly connected to one side of the push plate. The T-shaped slider at the bottom of the column is slidably connected to the T-shaped groove at the top of the trolley.

[0008] Motor 1 is fixedly connected to one side of the column. A bidirectional screw is fixedly connected to the output end of the motor 1. The other end of the bidirectional screw is rotatably connected to the surface of the column. A connecting block 1 is threadedly connected to the threaded surface of the bidirectional screw. One side of the connecting block 1 is slidably connected to one side of the push plate. An L-shaped plate is fixedly connected to the other side of the connecting block 1. There are two L-shaped plates. A laser rangefinder and a reflector are fixedly connected to the top of the two L-shaped plates, respectively.

[0009] A top plate is fixedly connected to the top of the column. A cylinder is fixedly connected to the top of the top plate. A connecting plate is fixedly connected to the output end of the cylinder. One side of the connecting plate is slidably connected to the surface of the column. A second motor is fixedly connected to one side of the connecting plate. A screw is fixedly connected to the output end of the second motor. The other end of the screw is rotatably connected to the inner side of the connecting plate. A second connecting block is threadedly connected to the threaded surface of the screw. A pneumatic gripper is fixedly connected to the bottom of the second connecting block.

[0010] The positioning mechanism for the door hinge tooling trolley also includes a limiting component, which is disposed on one side of the push plate.

[0011] The limiting assembly includes a limiting shell, a fixing block, a limiting block, a connecting block three, a pawl, a rotating shaft, and a ratchet. The limiting shell is fixedly connected to one side of the push plate, and the interior of the limiting shell is rotatably connected to the surface of the bidirectional screw. The fixing block is fixedly connected to the top of the limiting shell, and the surface of the limiting block engages with a groove on the top of the fixing block. The top of the connecting block three is hinged to the surface of the limiting block, and the surface of the connecting block three is slidably connected to a sliding groove on the top of the limiting shell. The pawl is fixedly connected to the bottom of the connecting block three. The rotating shaft is fixedly connected to the inner wall of the limiting shell, and the surface of the rotating shaft is rotatably connected to the interior of the pawl. The ratchet is fixedly connected to the surface of the bidirectional screw, and the outer edge of the ratchet meshes with the tooth surface of the pawl.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above solution, the door panel is placed on the platform of the trolley. The electric push rod is started, which pushes the push plate and column forward. Motor 1 is started, which drives the bidirectional screw to rotate. Due to the threaded connection, the L-shaped plates on both sides clamp the door panel and fix it on the platform through the connecting blocks on both sides. The length of the door panel is measured by the laser rangefinder and the reflector and fed back to the controller. After calculating the installation position of the hinge, Motor 2 is started, which drives the screw to rotate. The pneumatic gripper is driven by the connecting block 2 to pick up the hinge and adjust its horizontal position. The cylinder is started, which drives the connecting plate to move down. The pneumatic gripper places the hinge in the designated position for installation. Compared with manual measurement and positioning, the measurement error is reduced and the positioning accuracy is improved, ensuring accurate hinge installation and normal use of the door panel. At the same time, the controller automatically calculates the data, which greatly reduces the time consumed and ensures the efficiency of hinge installation.

[0014] After the door panel is fixed by the L-shaped plate, the sliding connecting block three drives the pawl to rotate along the shaft, engaging the ratchet. The rotating limit block engages the ratchet with the slot on the top of the fixing block, thus completing the limit. This effectively prevents positioning measurement errors caused by the rotation of the bidirectional screw when the device vibrates or when the motor is powered off, further ensuring the accuracy of the hinge installation.
