Description

Technical Field

[0001] This utility model relates to production equipment, specifically to a product lifting and positioning mechanism. Background Technology

[0002] Pulley products require assembly via pressing, for example, pressing the pulley bracket to the pulley shaft. During pressing, the product parts are positioned on a tooling plate, and a pressure head acts on the parts from top to bottom, pressing them together to form the product. In production, an assembly line method is used. The tooling plate positioning the product parts moves along the conveyor line to the pressing station. A lifting mechanism lifts the tooling plate, and after the tooling plate is removed from the conveyor line, the pressure head descends, pressing the product together. Because the pressure head forcibly presses the product parts together, the lifting mechanism supporting the tooling plate or product parts needs sufficient strength and precision to ensure that the pressure head accurately presses the product parts into the finished product. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a lifting mechanism that can accurately position the tooling plate and provide strong support for the product parts, so as to ensure that the press head can smoothly press the product parts into a molded product.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wedge-shaped lifting mechanism with dual precision positioning, comprising a first lifting mechanism and a second lifting mechanism. The first lifting mechanism includes a vertical cylinder fixedly mounted on the conveyor frame and a lifting plate connected to the vertical cylinder. The lifting plate is provided with a positioning post, and the bottom surface of the tooling plate is provided with a positioning hole that cooperates with the positioning post. The middle part of the lifting plate is provided with a lifting clearance hole. The second lifting mechanism includes a push rod that cooperates in the lifting clearance hole, a wedge block that abuts against the bottom end of the push rod, and a horizontal cylinder connected to the wedge block. The wedge block is slidably fitted on a guide plate, and the horizontal cylinder and the guide plate are fixedly mounted on the conveyor frame.

[0005] According to the above technical solution, the product part is positioned on a tooling plate. A conveyor line transports the tooling plate forward to the pressing station. A blocking device prevents the tooling plate from advancing. A vertical cylinder drives a lifting plate to rise, and a positioning pin on the lifting plate inserts into the positioning hole of the tooling plate, lifting the tooling plate off the conveyor line, thus initially positioning the product part. Then, a horizontal cylinder drives a wedge block to move horizontally. The wedge block acts on the bottom end of a push rod, lifting the push rod. The top end of the push rod passes upward through the tooling plate and supports the product part below. Afterward, the pressure head descends, pressing the product part into a molded product. The upward passage of the top end of the push rod through the tooling plate, supporting the product part while simultaneously repositioning the tooling plate and the product parts on it.

[0006] The lifting mechanism of this invention can accurately position the tooling plate and provide strong support for the product parts, so as to ensure that the pressure head can smoothly press the product parts into the molded product.

[0007] The lifting plate is fixedly mounted on the first guide rod, and the first guide sleeve is fitted on the first guide rod. The first guide sleeve is fixedly mounted on the conveyor frame.

[0008] There is a pair of first guide rods, which are set on the left and right sides of the lifting plate, and the bottom ends of the pair of first guide rods are connected by a connecting plate.

[0009] A guide module is provided in the lifting clearance hole, and the guide module has a guide hole. The push rod is fitted into the guide hole of the guide module.

[0010] A second guide rod is provided between the lifting plate and the connecting plate. The second guide rod passes through the guide plate and is fitted with a second guide sleeve. The second guide sleeve is connected to the top rod through a connector.

[0011] A return spring is fitted onto the second guide rod, located between the lifting plate and the second guide sleeve. When the push rod rises, the second guide sleeve rises accordingly, compressing the return spring. After the product is pressed and molded, the wedge block retracts and resets under the drive of the horizontal cylinder. Under the force of the return spring and gravity, the push rod descends and resets, detaching from the tooling plate. Even when the push rod reaches its lowest position, its top end remains within the guide hole of the guide module.

[0012] A pair of guide rails are provided on the guide plate, and the bottom of the wedge block is movably fitted in the pair of guide rails. Driven by a horizontal cylinder, the wedge block moves linearly along the pair of guide rails. Attached Figure Description
