Description

Technical Field

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

[0002] Machining can find a wide range of applications in industry, manufacturing and production to produce a wide range of parts, products and assemblies. Machining can encompass a number of different methods including milling, turning, drilling, grinding, EDM, laser cutting and more.

[0003] In the prior art, some irregular parts are often encountered during machining. However, due to the special shape of the parts, when machining a certain part, the parts cannot be directly fixed on the machine tool for processing. At this time, it is necessary to remake some fixtures that match the parts. After the parts are fixed, the fixtures are fixed on the machine tool to complete the machining process.

[0004] However, the fixtures required for processing irregular parts are specific and can only fix matching parts. When other parts need to be processed, the fixtures need to be remade, which is too costly. At the same time, the matching fixtures need to be repeatedly fixed on the machine tool during processing, which is too time-consuming and reduces work efficiency. Utility Model Content

[0009] Preferably, a processing device is installed on the top of the workbench, and a storage plate fixedly connected to the top of the workbench is provided directly below the processing device.

[0011] Preferably, a sliding groove matching the slider is provided inside the extension block and the moving block, a circular groove matching the positioning rod is provided at the top of the slider, and the slider is slidably connected to the extension block and the moving block.

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

[0013] The utility model proposes that a servo motor is started to make the bidirectional threaded screw drive the two groups of moving blocks to move relative to each other, so that the moving blocks drive the clamping plate pair to fit the two sides of the object through the fixed shaft, so that when the ball head rod contacts the object, the force is applied to squeeze the spring through the limit plate, and the limit plate can effectively slide inside the spring groove, and the multiple groups of ball head rods on both sides can better clamp and fix the object, which is convenient for better processing and prevents shaking during processing. At the same time, under the action of the ball head rod, irregular objects can be better clamped, which avoids the need for staff to process different clamps, better reduces costs, and further enhances work efficiency.

[0014] The utility model proposes that the positioning rod is pulled out and the slider is moved forward and backward, and the slider slides in the slide groove, so that the clamping plate leads the object to move through the ball head rod. When it moves to the required position, the positioning rod is inserted into the positioning hole and the circular groove to realize the positioning of the slider, effectively avoiding the need for workers to re-clamp the object and affect the processing efficiency. At the same time, the positioning rod can effectively position according to the required moving distance, thereby enhancing the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
