Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a positioning device for cutting processing of machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] In the prior art, when a cutting machine tool is in use, a metal workpiece is usually placed on the machine tool and clamped and positioned by a fixture. However, the existing positioning device can only clamp and position a single type of metal workpiece and cannot effectively clamp and position metal workpieces of different shapes, resulting in poor versatility of the device and failure to meet usage requirements. In addition, the existing positioning device cannot clamp and position metal workpieces of different sizes and requires manual adjustment, thereby affecting the overall work efficiency. Utility Model Content

[0004] The utility model mainly provides a positioning device for machine tool cutting processing which can clamp and position machines of different shapes and sizes.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a positioning device for machine tool cutting processing, comprising: a fixed plate, adjustment components are symmetrically arranged at both ends of the top of the fixed plate, a bracket is arranged on the top of the adjustment component, a motor is arranged on one side of a single bracket, the output end of the motor movably passes through the single bracket and is connected to a screw rod, a guide rod is fixedly connected to the side where the two brackets are close to each other, two movable blocks are arranged on the outer walls of the screw rod and the guide rod, one end of the movable block is fixedly connected to an arc clamping block, and a right-angle groove is opened on one side of the arc clamping block.

[0006] Preferably, the adjustment assembly includes two fixing frames, which are symmetrically arranged at the two ends of the top of the fixing plate, and electric cylinders are symmetrically arranged at the two ends of the fixing frames, and the output ends of the electric cylinders movably penetrate the fixing frames and are connected to sliding seats, and the brackets are fixedly installed on the top of the sliding seats. The sliding seats can be driven to slide left and right on the fixing frames through the extension and retraction of the electric cylinders, causing multiple arc-shaped clamping blocks to approach or move away from each other, thereby realizing clamping and positioning of metal workpieces of different sizes, thereby improving the versatility of the device without manual adjustment, thereby effectively improving the overall work efficiency.

[0007] Preferably, a fixing frame is provided at the bottom of the fixing plate, a dustproof net is provided at one end of the fixing frame, an axial flow fan is installed on one side of the dustproof net, and a square tube is connected to the top of the fixing frame, one end of the square tube movably passes through the fixing plate and is connected to a baffle plate. Suction is generated by the operation of the axial flow fan, so that metal debris and dust remaining on the fixing plate are affected by the suction and fall from the baffle plate through the square tube into the fixing frame. At the same time, the dustproof net can prevent metal debris and dust from damaging the axial flow fan, thereby reducing the difficulty of cleaning, improving cleaning efficiency, saving labor costs, and extending the service life of the device.

[0008] Preferably, a collection box is movably installed on the inner side of the fixed plate, and a guide block is provided at one end of the interior of the collection box. A handle is provided at one end of the collection box, and the guide block can enable the metal debris and dust sucked into the fixed frame to fall correctly into the collection box. By grasping and pulling the handle, the collection box can be taken out of the fixed frame, thereby cleaning the metal debris and dust accumulated inside the collection box, thereby improving the cleaning efficiency, preventing debris and dust from escaping into the air, protecting the working environment, and ensuring the physical and mental health of the staff.

[0009] Preferably, connecting frames are symmetrically arranged on both sides of the bottom of the fixed plate, and the bottom of the connecting frame is fixedly connected to a base. The connecting frame cooperates with the base to provide stable support for the fixed frame, preventing the metal workpiece from shifting or falling off due to vibration during processing, thereby improving the overall stability of the device.

[0010] Preferably, mounting bolts are installed at the four corners of the top of the base, and gaskets are provided on the outer sides of the mounting bolts. The device can be completely fixed on the machine tool by tightening the mounting bolts. At the same time, the gaskets increase the friction force to prevent the mounting bolts from falling off, thereby improving the stability of the device during use.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, the motor drives the screw rod to rotate, so that the movable block can slide left and right on the guide rod, causing the arc-shaped clamping block to approach or move away, thereby clamping and positioning the metal workpiece. At the same time, the right-angle groove can be used to effectively clamp and position the rectangular or irregular metal workpiece, thereby improving the versatility of the device, reducing the difficulty of use, improving the positioning efficiency and accuracy, and meeting the needs of actual use.

[0013] 2. In the utility model, the sliding seat can be driven to slide left and right on the fixed frame through the extension and retraction of the electric cylinder, so that multiple arc-shaped clamping blocks can be moved closer to or farther away from each other, thereby clamping and positioning metal workpieces of different sizes, thereby improving the versatility of the device and eliminating the need for manual adjustment, thereby effectively improving the overall work efficiency.
