Description

Technical Field

[0001] The utility model relates to a positioning mechanism, in particular to a positioning mechanism for polishing automobile die castings, and belongs to the technical field of die casting processing. Background Art

[0002] Die casting is a kind of pressure-casting part. It uses a pressure casting machine equipped with a casting mold to pour liquid metals such as copper, zinc, aluminum or aluminum alloy into the inlet of the die casting machine. The die casting machine is die-cast to cast copper, zinc, aluminum or aluminum alloy parts in the shape and size limited by the mold. Such parts are usually called die castings.

[0003] During the production and processing of die-casting parts, it is often necessary to grind the molded die-casting parts after demolding and to position and fix them by a clamp. A clamp for grinding aluminum-magnesium die-casting parts is disclosed in the Chinese patent application publication specification CN215903318U. The clamp is configured to drive a first clamping plate and a second clamping plate to complete the horizontal and vertical positioning and clamping of the die-casting parts, thereby realizing multi-directional fixation of the die-casting parts, enhancing stability, shortening the processing time of the die-casting parts, improving processing efficiency, and reducing the labor intensity of the staff.

[0004] Although the above patent can complete the multi-directional positioning and clamping of the die-casting by the first clamping plate and the second clamping plate, when the die-casting is a special-shaped die-casting, due to the design of the planes of the first clamping plate and the second clamping plate, the clamping of the special-shaped die-casting is not firm enough, so that the positioning is not firm enough when facing the special-shaped die-casting. At the same time, the connection method of the first clamping plate and the second clamping plate is fixed, which makes it difficult to disassemble and replace the first clamping plate and the second clamping plate when they are damaged after long-term use.

[0007] (2) Technical solution

[0008] The utility model is implemented through the following technical scheme: a positioning mechanism for grinding automobile die-castings, including a platform plate, two sliding plates are symmetrically arranged on the upper surface of the platform plate, the two sliding plates are slidably connected to the platform plate, a plurality of positioning modules are arranged on the side surfaces of the two sliding plates close to each other, a driving device is arranged on the bottom surface of the platform plate, a groove is opened on the upper surface of the platform plate, and a plurality of support columns are fixed to the bottom surface of the platform plate.

[0009] The positioning module includes a card block, a positioning telescopic rod is installed on the side of the card block, an auxiliary ball is fixed to the other end of the positioning telescopic rod, and a positioning plate is hinged on the outer surface of the auxiliary ball, which is beneficial to the stability of the positioning plate. Through the hinge connection between the positioning plate and the auxiliary ball, the positioning plate can rotate when contacting the special-shaped die-casting, thereby increasing the contact area between the positioning plate and the special-shaped die-casting, so that the positioning plate can clamp the special-shaped die-casting more stably.

[0010] The positioning module also includes a positioning spring, which is arranged on the outer surface of the positioning telescopic rod. One end of the positioning spring is connected to the block, and the other end of the positioning spring is connected to the positioning plate, which is beneficial to the stability of the positioning spring. The elastic force of the positioning spring can push the positioning plate and the special-shaped die-casting to fit more closely.

[0011] A chamber is formed on a side of the clamping block away from the positioning telescopic rod, and a limiting groove corresponding to the chamber is formed on the sliding plate. The interior of the chamber is slidably connected to a limiting block, and the limiting block is engaged with the limiting groove, which is beneficial to the stability of the limiting block. The clamping block can be quickly disassembled by engaging the limiting block with the limiting groove.

[0012] A limiting spring is installed on one side of the limiting block close to the inner wall of the chamber, and the other end of the limiting spring is connected to the clamping block, which is beneficial to the stability of the limiting spring. The elastic force of the limiting spring can push the limiting block to move, ensuring that the limiting block and the limiting groove are stably clamped.

[0013] The driving device includes a driving motor, a driving gear is installed at the output end of the driving motor, a tooth plate is slidably connected to the inner wall of the groove, the tooth plate is fixed to its corresponding sliding plate, the driving gear is meshed with the tooth plate, and the output end of the driving motor can drive the driving gear to rotate and then drive the tooth plate to move, and the positioning module is driven to move through the movement of the tooth plate.

[0015] The utility model provides a positioning mechanism for polishing automobile die castings, which has the following beneficial effects:

[0016] 1. The positioning mechanism for polishing automobile die-castings is hinged by setting an auxiliary ball and a positioning plate, so that when the positioning plate contacts the special-shaped die-casting, the positioning plate can adjust the angle according to the contact surface, thereby increasing the contact area between the positioning plate and the special-shaped die-casting, so that the positioning plate can contact the special-shaped die-casting more closely, solving the problem that the common positioning mechanism in the prior art is not firmly positioned when facing the special-shaped die-casting.

[0017] 2. The positioning mechanism for polishing automobile die-casting parts is connected by setting a limit block and a limit groove. The limit block is pushed to disengage from the limit groove to release the connection of the limit block, so that the block can be quickly disassembled. When the positioning device fails and needs to be disassembled and replaced, the disassembly and replacement can be completed quickly, thereby reducing the time required for disassembly and replacement and improving work efficiency.

The outer surface of the auxiliary ball 303 is hinged with a positioning plate 304, which is beneficial to the stability of the positioning plate 304. Through the hinge of the positioning plate 304 and the auxiliary ball 303, the positioning plate 304 can rotate when it contacts the special-shaped die-casting, increasing the contact area between the positioning plate 304 and the special-shaped die-casting, so that the positioning plate 304 can clamp the special-shaped die-casting more stably. The positioning module 3 also includes a positioning spring 305, which is arranged on the outer surface of the positioning telescopic rod 302, one end of the positioning spring 305 is connected to the block 301, and the other end of the positioning spring 305 is connected to the positioning plate 304, which is beneficial to the stability of the positioning spring 305.

[0028] Please refer to Figure 1 , Figure 3 and Figure 4 A chamber is provided on one side of the block 301 away from the positioning telescopic rod 302, and a limiting groove is provided on the sliding plate 2 corresponding to the chamber. The internal sliding connection of the chamber is limited to a limiting block 306, and the limiting block 306 is engaged with the limiting groove, which is beneficial to the stability of the limiting block 306.
