Description

Technical Field

[0001] The utility model relates to the technical field of CNC machine tool fixtures, and particularly relates to an automatic loading and unloading clamping mechanism for machine tools. Background Art

[0002] A CNC machine tool, short for a numerically controlled machine tool, is an automated machine tool equipped with a program control system. This control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, and input it into the numerical control device through an information carrier. After arithmetic processing, the numerical control device issues various control signals to control the actions of the machine tool, and automatically processes parts according to the shape and size required by the drawing.

[0003] In existing CNC machine tools, since only one set of fixtures is usually provided for loading and unloading, when loading and unloading the CNC machine tool, the machine tool needs to first remove the workpiece polished on the CNC machine tool, and then pick up the material and install the material on the machine tool fixture. This results in a reduction in the efficiency of material installation and removal in the above process, indirectly affecting the machining efficiency of the machine tool for workpieces. Therefore, there are still certain deficiencies.

[0004] In summary, it is necessary to invent an automatic loading and unloading clamping mechanism for machine tools. Content of the Utility Model

A moving sliding groove is formed at the position corresponding to the fixed chuck on the outer wall of the fixture mounting plate, and the fixed chuck is slidably connected to the inner wall of the moving sliding groove.

[0012] Preferably, a thumb cylinder is fixed to the bottom end of the outer wall of the fixture mounting plate and on the opposite sides of the fixed chucks through fixing plates.

[0022] Refer to the attached Figures 1-4 , an automatic loading and unloading clamping mechanism for a machine tool provided by the present invention includes a machine tool body 100. A loading and unloading truss 200 is installed on the outer wall top of the machine tool body 100 and close to the feeding port. A transverse moving seat 210 is slidably connected to the loading and unloading truss 200. A longitudinal moving guide rail 220 is slidably connected to the rear side of the outer wall of the transverse moving seat 210. The provided loading and unloading truss 200 is used to drive the clamping mechanism 300 to move horizontally through the transverse moving seat 210, and the provided longitudinal moving guide rail 220 is used to drive the clamping mechanism 300 to move up and down. The clamping mechanism 300 can perform four-way movement through the cooperation of the transverse moving seat 210 and the longitudinal moving guide rail 220, so that the clamping mechanism 300 can better load and unload the machine tool;

[0023] A clamping mechanism 300 is installed at the bottom end of the longitudinal moving guide rail 220. The clamping mechanism 300 includes a support plate 310 which is fixed to the bottom end of the outer wall of the longitudinal moving guide rail 220. On one side of the outer wall of the support plate 310, a side rotating plate 330 is rotatably connected. The side rotating plate 330 is provided to fix two fixture mounting plates 350 through a main connecting rod 340. At one end of the support plate 310 away from the side rotating plate 330, a driving motor 320 is fixed. The output shaft of the driving motor 320 passes through the support plate 310 and is fixed to the side end of the outer wall of the side rotating plate 330. The driving motor 320 is provided to drive the side rotating plate 330 to rotate through a rotating shaft, so as to be able to adjust the direction of the two fixture mounting plates 350. At the end of the side rotating plate 330 away from the support plate 310, a main connecting rod 340 is fixed. At the bottom end and the side end of the outer wall of the main connecting rod 340, fixture mounting plates 350 are fixed through connecting rods. The number of the fixture mounting plates 350 is two, and the two fixture mounting plates 350 are arranged at an angle of 90°. The two fixture mounting plates 350 are provided to install fixed chucks 360. The two fixture mounting plates 350 are arranged at an angle of 90° to facilitate the operator to adjust the direction of the two fixture mounting plates 350 through the driving motor 320. By providing two fixed chucks 360, one fixed chuck 360 can clamp the material to be placed, and the other fixed chuck 360 can clamp and remove the processed workpiece, so that the operator can complete the disassembly, replacement of the material and the workpiece;

[0024] On the outer wall of one side of the fixture mounting plate 350 away from the main connecting rod 340, fixed chucks 360 are slidably connected. At the center of each fixed chuck 360, an arc-shaped clamping groove for clamping the material is provided. Specifically, the two fixed chucks 360 cooperate with the arc-shaped clamping grooves to clamp and fix the material and the workpiece. At the position corresponding to the fixed chuck 360 on the outer wall of the fixture mounting plate 350, moving chutes are provided. The fixed chucks 360 are slidably connected to the inner walls of the moving chutes. At the bottom end of the outer wall of the fixture mounting plate 350 and on the opposite sides of the fixed chucks 360, thumb cylinders 361 are fixed through fixing plates. The output ends of the two thumb cylinders 361 are fixed to the corresponding positions on the side ends of the inner walls of the fixed chucks 360. A material detection probe 362 is provided at the bottom end of the outer wall of the fixture mounting plate 350. The material detection probe 362 is arranged at the center of the arc-shaped clamping groove. Specifically, the provided material detection probe 362 can position the workpiece to be clamped. The material detection probe 362 can specifically be an industrial camera. By providing the thumb cylinders 361, the fixed chucks 360 can be controlled to move, so that the fixed chucks 360 can clamp or release the material.

[0025] The usage process of the present utility model is as follows: First, personnel can install the device on the machine tool body 100 according to the above description. After debugging, the material to be processed can be placed on the bin plate of the machine tool body 100. The longitudinally moving guide rail 220 can drive the clamping mechanism 300 to move downward, so that the bottom fixture mounting plate 350 is above the material to be processed. Then, through the material detection probe 362, the distance between the fixed chuck 360 and the material can be detected. When the control thumb cylinder 361 extends, the two fixed chucks 360 are opened outward. Then, the material will be located between the arc-shaped clamping grooves formed in the fixed chuck 360. When the clamping mechanism 300 descends to the clamping position, the longitudinally moving guide rail 220 will stop the movement of the fixed chuck 360. At the same time, the thumb cylinder 361 can contract, so that the fixed chuck 360 clamps and fixes the outer wall of the material through the arc-shaped clamping groove. After the fixing is completed, according to the pre-written program, the laterally moving seat 210 and the longitudinally moving guide rail 220 will move the clamping mechanism 300 to the processing fixture of the machine tool body 100 again, and make the other fixed chuck 360 align with the processed object. Then, through the above method, the vacant fixed chuck 360 clamps and fixes the object. After the fixing is completed, the driving motor 320 is powered on to drive the side rotating plate 330 to rotate, so that the fixed chuck 360 clamping the material can align with the processing fixture of the machine tool body 100. Then, the material is inserted into the processing fixture to align and fix it. After the fixing is completed, the device can drive the clamping mechanism 300 to retract. Then, the driving motor 320 drives the side rotating plate 330 to rotate so that the fixed chuck 360 clamping the workpiece faces downward, and the device can place the workpiece on the bin plate. Then, repeat the above steps to continue to complete the replacement of the workpiece and the material.

[0026] The above are only the preferred embodiments of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
