Description

Technical Field

[0001] This utility model relates to the field of aluminum parts processing technology, specifically to a general-purpose automatic positioning fixture for aluminum parts processing. Background Technology

[0002] Aluminum is a silvery-white, lightweight metal. It is malleable. Commercially available aluminum is often produced in rod, sheet, foil, powder, strip, and wire forms. Due to its low density and excellent ductility, thermal conductivity, and electrical conductivity, aluminum is widely used in modern industrial production and daily life. It is the world's second most produced and consumed non-ferrous metal after steel. During aluminum parts processing, the material is relatively soft due to its physical properties and is easily deformed under external forces, thus requiring multi-directional fixation.

[0003] Application number CN201510754296.0 discloses a universal fixture for machining aluminum parts. This fixture uses self-adjustable horizontal and vertical baffles to fix aluminum parts from all directions. Furthermore, multiple baffles can be used to create multiple spaces, allowing for the simultaneous fixing of multiple aluminum parts. However, this design has limitations. When the aluminum part is cylindrical, the fixture is not convenient for fixing it, thus limiting its use.

[0004] Therefore, we propose a universal automatic positioning fixture for aluminum parts processing. Utility Model Content

[0005] The main purpose of this utility model is to provide a universal automatic positioning fixture for aluminum parts processing. Through the design of the limiting mechanism, the fixture body can fix and clamp the cylindrical aluminum parts. Through the cooperation of the clamping parts, clamping plate, sliding groove, clamping slot and the first bolt, it is easy to assemble the upper limit mechanism in the processing groove on the fixture body, and it is also easy to disassemble. The limiting mechanism can be used flexibly and can effectively solve the problems in the background art.

Then, the knob located in the groove is turned clockwise. The knob drives the rotating rod to rotate, and the rotating rod drives the first gear to rotate. Since the first gear and the second gear mesh and are arranged at right angles, the second gear can drive the threaded rod to rotate. Through the threaded engagement between the threaded rod and the push plate, the push plate can move the movable plate toward the cylindrical aluminum part in the limiting channel through the push rod until the cylindrical aluminum part is fixed between the movable plate and the clamping plate. Then, the bottom end of the second bolt passes through the knob and is fixedly connected to the inner wall of the bottom end of the groove.

[0011] Specifically, the upper end face of the fixture body is provided with slots that are adapted to the clamping plate at both ends, and the upper part of the inner wall at both ends of the processing groove is provided with sliding grooves for installing clamping parts, and four sets of sliding grooves are arranged in parallel.

[0012] Specifically, the side of the clamp away from the card plate is connected to the movable plate via a top rod, and a limiting channel for placing cylindrical aluminum parts is provided between the movable plate and the clamp.

[0013] Specifically, the clamping plate and the movable plate are provided with arc-shaped grooves on the side near the limiting channel, and anti-slip pads are fixedly glued to the side of the clamping plate and the movable plate near the arc-shaped grooves.

[0014] Specifically, the top of the clamp is provided with a groove for installing the knob. The groove is located directly above the cavity. The first gear and the second gear are installed in the cavity respectively. The top of the rotating rod passes through the inner wall of the top of the cavity and is fixedly connected to the bottom of the knob. The knob is fixedly connected to the inner wall of the bottom of the groove by a second bolt.

[0015] Specifically, the threaded rod and the push plate are both located inside the mounting cavity. One end of the threaded rod passes through the inner wall of one side of the mounting cavity and is fixedly connected to one end of the second gear. The push plate is sleeved on the threaded rod. A top rod is vertically inserted into one side of the push plate. The end of the top rod away from the push plate passes through the clamp and is vertically inserted into one side of the movable plate.
