Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a positioning device for hardware processing. Background Art

[0002] Hardware processing is the process of using lathes, milling machines, drilling machines, polishing machines and other machines to process raw materials into various parts according to customer drawings or samples, such as: screws, motor shafts, model car parts, fishing gear accessories, speaker product casings, mobile power casings, etc.

[0003] In the prior art, when processing hardware, a three-jaw chuck is usually required to position the hardware. The three-jaw chuck is often placed vertically. When installing hardware, the three-jaw chuck often needs to be placed horizontally to facilitate processing. However, the positioning device in the prior art is not convenient for the three-jaw chuck to switch between the vertical and horizontal states, has poor versatility, and is not conducive to use. Therefore, we have introduced a positioning device for hardware processing. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning device for hardware processing, which can enable a three-jaw chuck to quickly switch between horizontal and vertical states, has strong versatility and is easy to use, so as to solve the problems raised in the above-mentioned background technology.

[0006] The fixing plate is fixedly provided with an L-shaped plate at the upper end of the base through a supporting seat, and a rotating plate is rotatably provided at the corner of the inner wall of the L-shaped plate through a movable connecting piece, and the other end of the rotating plate is provided with a three-jaw chuck, and the side wall of the rotating plate is provided with a mounting hole, and the inner walls of both sides of the L-shaped plate are fixedly provided with mounting blocks matching the mounting hole, and the mounting hole is provided with a rectangular hole in the middle of a hole wall on one side close to the three-jaw chuck, and a clamping mechanism is provided in the rectangular hole, and the clamping mechanism includes a rectangular rod, and the rectangular rod is slidably arranged in the rectangular hole, and the side wall of the mounting block is provided with a rectangular groove matching the rectangular rod, one end of the rectangular rod extends to the outside of the rectangular hole and is fixedly connected to the middle of the three-jaw chuck, and the other end of the rectangular rod extends into the mounting hole, and a strip groove is provided on one side hole wall of the rectangular hole, and a tightening mechanism is slidably provided in the strip groove.

[0007] Preferably, the clamping mechanism includes a slider, which is slidably arranged in the strip groove on a side away from the three-jaw chuck, one end of the slider extends outside the strip groove and is fixedly connected to the rectangular rod, and a spring is fixedly provided on the groove wall on one side of the strip groove close to the three-jaw chuck.

[0008] Preferably, the spring is always in a compressed state.

[0009] Preferably, the two mounting blocks are both chamfered at their edges on one side away from the L-shaped plate.

[0010] Preferably, the chamfer angle is set to 45°.

[0011] Preferably, support blocks are fixedly provided at the four corners of the bottom of the base.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The positioning device for hardware processing is provided with a movable connecting piece, a rotating plate, a mounting block, a rectangular rod, a slider and a spring. When it is necessary to switch the placement state of the three-jaw chuck, the three-jaw chuck is pulled, and the three-jaw chuck drives the slider on the rectangular rod to squeeze the spring. At the same time, the rectangular rod is no longer clamped with the rectangular groove. At this time, the rotating plate can be rotated 90 degrees, and the rotating plate drives the three-jaw chuck to rotate 90 degrees. When the rectangular rod contacts the upper mounting block, the chamfer of the mounting block pushes the rectangular rod. When the rectangular rod corresponds to the position of the upper rectangular hole, the spring pushes the slider and drives the rectangular rod to be clamped into the rectangular groove, so that the three-jaw chuck can be quickly switched between the horizontal and vertical states. The chuck has strong versatility and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
