Description

Technical Field

[0001] This utility model relates to a workpiece fixture, specifically a cylindrical workpiece fixture for a drilling and milling machine tool, belonging to the field of CNC machine tool technology. Background Technology

[0002] CNC machine tools are machine tools that use digital information to achieve automatic control. They use codes composed of prescribed text, numbers, and symbols to create a machining program, which is then input into the CNC device via a control medium. The CNC device analyzes and processes the program, issuing various signals and instructions corresponding to the machining program for automatic processing. Drilling and milling machine tools, on the other hand, are machine tools that integrate drilling, milling, boring, and grinding. They are used for machining small to medium-sized parts, achieving the desired results by drilling, milling, boring, and grinding precision components.

[0003] Currently, traditional machine tools mostly fix square workpieces. When it is necessary to fix cylindrical workpieces, the original fixing fixtures become useless, and the debris generated during the machining process is prone to fall into the gaps of the machine tool body.

[0004] Therefore, a cylindrical workpiece fixture for drilling and milling machine tools is proposed here. Utility Model Content

[0005] This utility model proposes a cylindrical workpiece fixture for a drilling and milling machine tool to solve the problems in the prior art where it is inconvenient to fix cylindrical workpieces and where chips during processing easily fall into the gaps of the machine tool body.

[0006] This utility model is achieved through the following technical solution: a cylindrical workpiece fixture for a drilling and milling machine tool, including a clamping assembly and a support plate installed on the side of the machine tool body, a fixing assembly is provided inside the support plate, and a collection box is fixedly connected to the surface of the support plate through the fixing assembly;

[0007] The clamping assembly includes a mounting part fixed to the side of the machine tool body. The mounting part has a transmission chamber inside, and a movable plate is movably arranged inside the transmission chamber. A connecting rod is hinged to the side of the movable plate, and a movable block is hinged to the other end of the connecting rod. A clamping plate for fixing a cylindrical workpiece is fixed to the side of the movable block, and an arc-shaped surface is formed on the side of the clamping plate.

[0008] Furthermore, a motor is installed inside the transmission chamber, and a threaded rod is fixed to the output end of the motor. A threaded tube is threadedly connected to the surface of the threaded rod, and the end face of the threaded tube is fixed to the side of the moving plate. The moving plate moves inside the transmission chamber through the motor, the threaded rod, and the threaded tube.

[0009] Furthermore, the surface of the mounting part is provided with a movable groove, the transmission chamber is connected to the movable groove, the connecting rod passes through the movable groove, and the side of the mounting part is also provided with a moving groove, the movable block is movably passed through the moving groove.

[0010] Furthermore, a slider is fixed on the lower surface of the collection box, and a groove corresponding to the slider is opened on the surface of the support plate. The slider moves inside the groove. There are two sliders and two grooves, which are symmetrically arranged on the lower surface of the collection box.

[0011] Furthermore, the fixing component includes a connecting plate disposed on one side of the support plate, a fixing rod fixed to the side of the connecting plate, a telescopic groove formed on the surface of the support plate, a fixing groove corresponding to the fixing rod formed on the side of the slider, one end of the fixing rod passing through the telescopic groove and inserted inside the fixing groove, and the end face of the fixing rod inserted into the fixing groove being an inclined surface.

[0012] Furthermore, a baffle is fixed to the outer periphery of the fixing rod, and a spring is also sleeved on the outer periphery of the fixing rod. The two ends of the spring are respectively fixed to the side of the baffle and the inner wall of the telescopic groove. A stop block is also fixed to the side of the support plate. There are two baffles, which are symmetrically arranged on both sides of the connecting plate. There are multiple fixing grooves, which are evenly arranged on the side of the slider.

[0013] This utility model provides a cylindrical workpiece fixture for a drilling and milling machine tool, which has the following beneficial effects:

[0014] 1. The cylindrical workpiece fixture for drilling and milling machine tools is driven by a motor to rotate a threaded rod, which in turn drives a threaded tube to move. The threaded tube then drives a movable plate fixed to its end face to move. A connecting rod hinged to the side of the movable plate drives a movable block hinged to its other end to move vertically, thereby moving the clamping plate. The clamping force is adjusted according to the size of the cylindrical workpiece, thus clamping and fixing the cylindrical workpiece. It is not limited by the diameter of the cylindrical workpiece, which improves the applicability of the device.

[0015] 2. The cylindrical workpiece fixture for the drilling and milling machine tool has a collection box fixed to the surface of the support plate by a fixing component. This effectively collects and stores the chips generated during processing, preventing chips from scattering in the gaps of the machine tool, reducing chip accumulation inside the machine tool, lowering the frequency and difficulty of cleaning and maintenance, and keeping the inside of the machine tool clean. At the same time, the fixing component not only keeps the collection box stable during processing, preventing shaking, movement or loosening, and preventing chip leakage or affecting machine operation, but also facilitates the disassembly, cleaning and replacement of the collection box by the operator, reducing maintenance time.

A telescopic groove 302 is opened on the surface of the support plate 3. A fixing groove 402 corresponding to the fixing rod 501 is opened on the side of the slider 401. One end of the fixing rod 501 passes through the telescopic groove 302 and is inserted inside the fixing groove 402. The end face of the fixing rod 501 that passes through the fixing groove 402 is an inclined surface. A baffle 503 is fixed to the outer periphery of the fixing rod 501. A spring 504 is also sleeved on the outer periphery of the fixing rod 501. The two ends of the spring 504 are... The support plate 3 is fixed to the side of the baffle 503 and the inner wall of the telescopic groove 302. There are also two baffles 503, which are symmetrically arranged on both sides of the connecting plate 502. There are multiple fixing grooves 402, which are evenly arranged on the side of the slider 401. The cylindrical workpiece fixture for the drilling and milling machine tool is fixed to the surface of the support plate 3 by the fixing component 5.
