Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a fixing device for marking a milling machine tool. Background Art

[0002] Milling is a mechanical processing method that uses a milling cutter as a tool to process the surface of an object. Milling machines include horizontal milling machines, vertical milling machines, gantry milling machines, copy milling machines, universal milling machines, and bar milling machines. Milling refers to the use of rotating multi-edged tools to cut workpieces. It is a highly efficient processing method. During operation, the tool rotates (as the main motion) and the workpiece moves (as the feed motion). The workpiece can also be fixed, but the rotating tool must still move at this time. Machine tools used for milling include horizontal milling machines or vertical milling machines, as well as large gantry milling machines.

[0003] The utility model patent with authorization announcement number CN208712952U discloses a milling machine tool, including a clamping mechanism, which includes a screw hole, a slide groove, two baffles, a clamping plate, and a bolt. A plurality of the slide grooves are equidistantly provided on the surface of the placement plate, and the clamping plate is slidably connected to the inside of the slide groove. One end of the clamping plate is fixedly connected to one of the baffles, and the other baffle is arranged on the surface of the placement plate. The surface of the clamping plate is symmetrically threaded with two groups of the bolts, and the bolts penetrate the placement plate and are threadedly connected to the screw hole, so that the material is fully placed on the plate body for clamping processing, saving materials and having a good fixing effect.

[0004] In the above device, one side of the workpiece is pressed against the baffle, and the other side is clamped by pushing the clamping plate close to the workpiece. Only the two sides of the workpiece are clamped, and during the processing, it is easy to deviate, affecting the processing accuracy. Utility Model Content

[0005] The utility model aims to provide a fixing device for marking a milling machine tool, which can clamp and fix the four sides of a workpiece and has the effect of ensuring the processing accuracy.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a fixing device for marking a milling machine tool, comprising a mounting plate, baffles are symmetrically arranged on the mounting plate, the baffles are slidably connected to the mounting plate, a slide groove is opened on the mounting plate, the baffle is embedded in the slide groove and is slidably connected to the slide groove, a first driving component is arranged on the mounting plate to control the two baffles to approach or move away from each other to clamp the workpiece horizontally, limiting plates are arranged at both ends of the baffle, the limiting plates are arranged parallel to the slide groove, and a second driving component is arranged on the mounting plate to control the distance between the two limiting plates to clamp the workpiece longitudinally.

[0007] By adopting the above technical solution, the workpiece is placed between two baffles and two limit plates. The first driving component controls the two baffles to approach each other until they collide with the two sides of the workpiece. Then the second driving component controls the two limit plates to collide with the two ends of the workpiece, thereby fixing the four sides of the workpiece, effectively preventing the workpiece from deviating during the processing and affecting the processing accuracy.

[0009] The moving rod is threadedly connected, the end of the driving rod is fixedly connected to a driving motor, and the driving motor is fixedly connected to the mounting plate.

[0010] By adopting the above technical solution, the driving motor controls the rotation of the driving rod. Under the action of the threads with the same pitch and opposite rotation direction on the driving rod, the two baffles move synchronously in opposite directions, thereby realizing the horizontal clamping of the workpiece.

[0011] The utility model is further configured as follows: two rotating rods are rotatably connected between the two limit plates, the two rotating rods are arranged in parallel, and the centers of the rotating rods are rotatably connected to the mounting plate.

[0016] By adopting the above technical solution, the threaded rod is rotated, and the limit plate connected to the threaded rod moves along its own length direction, driving the rotating rod to rotate. The rotation of the rotating rod causes the other limit plate to approach the limit plate connected to the threaded rod, thereby clamping the workpiece longitudinally.

[0017] The utility model is further configured as follows: another end of the limit plate is fixedly connected with a spring, one end of the spring away from the limit plate is fixedly connected to the mounting plate, and the spring is located at one end of the limit plate away from the threaded rod.

[0018] By adopting the above technical solution, the spring can assist the two limit plates to return to their original state after the clamping work is completed.

[0020] By adopting the above technical solution, the hand wheel is turned to control the rotation of the threaded rod. Since the threaded rod is threadedly connected to the mounting seat, the limit plate moves in its own length direction.

[0021] The utility model is further configured as follows: the baffle plate and the limit plate are provided with a rubber layer in contact with the workpiece.

[0022] By adopting the above technical solution, the rubber layer can increase the friction force to make the clamping more stable, and at the same time protect the edge of the workpiece from damage.
