Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a machine tool for processing special-shaped curved surfaces. Background Art

[0002] Special-shaped surface machining machine tools are machine tools specially designed for machining workpieces with complex and irregular surface shapes. Special-shaped surface machining machine tools are widely used in industries such as aerospace, automobiles, mold manufacturing, medical equipment and precision instruments to process parts and workpieces with complex surface shapes. The special design and functions of these machine tools make the machining process more efficient and precise, and can meet the requirements of complex surface machining.

[0003] The fixtures used in existing special-shaped surface processing machines can generally only fix one type of parts, which means that when processing different types of parts, the fixture needs to be replaced in order to perform normal work. The whole process is very troublesome. In addition, when collecting waste chips in existing special-shaped surface processing machines, the filter screen used has been used for a long time, and some waste chips will accumulate on the surface of the filter screen, which will further cause the collection system to be blocked, affecting the waste chip collection work of the entire device.

[0004] The purpose of this application is to design a machine tool for processing special-shaped surfaces, which is equipped with a clamp device that can fix different types of parts, saving the time spent on replacing the clamp and greatly improving the working efficiency of the entire machine tool. At the same time, a vibration structure is added to the ordinary filtering structure, which can effectively prevent waste chips from accumulating on the filter net and affecting the entire waste chip collection work. Utility Model Content

[0005] The purpose of the present application is to process workpieces with complex and irregular curved surface shapes. Compared with the prior art, a special-shaped curved surface processing machine tool is provided. A mounting table is installed inside the machine tool, and a fixture is fixed on the mounting table through a mounting plate and a fixing assembly. Before the machine tool starts working, it is only necessary to place the workpiece on the upper end of the control box, and then use a wrench to tighten the nut at one end of the threaded rod. As the threaded rod rotates, the two sets of clamps begin to slowly approach, and then the first rotating block and the second rotating block will rotate according to different types of workpieces to fix the parts between the clamps. The use of the above-mentioned clamps saves the time spent on replacing the clamps and effectively improves the working efficiency of the entire machine tool. A protective box is also installed inside the machine tool. A vibration plate with a vibration structure is installed inside the protective box through a spring sheet. When the motor is started, the eccentric blocks on both sides of the motor will drive the entire vibration plate to vibrate, effectively avoiding the accumulation of waste chips generated by processing on the vibration plate, affecting the entire waste chip collection work.

[0006] Furthermore, a plurality of evenly distributed slots are provided at the upper end of the mounting table, and four evenly distributed openings are provided at the upper end of the mounting plate. A fixing component is installed at the opening on the mounting plate, and the lower end of the fixing component is inserted in the slot. Before processing the parts, the fixture needs to be installed. The grooves on the mounting table and the mounting plate enable the fixture to be stably fixed on the mounting table by the fixing component, thereby ensuring that the entire parts processing process can proceed smoothly.

[0007] Furthermore, the fixing assembly includes a screw rod installed on the mounting plate, and the external thread of the screw rod is connected to a nut, and the external rotating sleeve of the screw rod is provided with a gasket. When installing the clamp, it is necessary to first place the lower end of the screw rod into the groove inside the mounting platform, and then clamp the upper end of the screw rod in the groove on the mounting plate, and then install the gasket and nut on the screw rod in turn, and finally tighten the nut at each location, so that the clamp can be stably fixed on the upper end of the mounting platform.

[0008] Furthermore, two threads in opposite directions are symmetrically distributed on the threaded rod, and one end of the threaded rod is fixedly connected to a hexagonal nut. When fixing the part, the nut at one end of the threaded rod is turned by a wrench, which drives the threaded rod to start rotating. The connecting block starts to move closer because of the two threads in opposite directions on the threaded rod, and finally the part can be stably fixed on the fixture.

[0009] Furthermore, the outer wall of the upper end of the gathering plate is designed to be evenly concave downward, and a rectangular opening connected to the protective box is provided at the upper end of the gathering plate. When the waste chips generated during the processing begin to enter the gathering plate from the passing plate, the surface of the gathering plate is concavely designed, so that the waste chips can quickly enter the vibration plate from the opening on the gathering plate, thereby improving the efficiency of the waste chip collection work.

[0010] Furthermore, a plurality of filter holes are evenly arranged on the vibration plate, and the vibration plate is placed obliquely inside the protective box. When waste chips enter the upper end of the vibration plate, the filter holes on the vibration plate can filter out some cutting fluid mixed in the waste chips, and the remaining waste chips will be discharged from the discharge port along with the vibration of the vibration plate. The obliquely placed vibration plate can prevent waste chips from remaining on the vibration plate.

[0011] Furthermore, the spring sheet is made of stainless steel, and the upper and lower ends of the spring sheet are respectively fixed to the lower end of the vibration plate and the inner wall of the protection box by screws and connecting blocks. When the vibration plate vibrates, the four groups of spring sheets will be deformed. At this time, the spring sheet can avoid loosening under the action of the screws, thereby ensuring the normal vibration process of the vibration plate.

[0012] Compared with the prior art, the advantages of this application are:

[0013] (1) The upper end of the mounting table is provided with a plurality of evenly distributed slots, and the upper end of the mounting plate is provided with four evenly distributed openings. A fixing component is installed at the opening on the mounting plate, and the lower end of the fixing component is inserted into the slot. Before processing the parts, the fixture needs to be installed. The grooves on the mounting table and the mounting plate enable the fixture to be stably fixed on the mounting table by the fixing component, thus ensuring that the entire parts processing process can proceed smoothly.

[0014] (2) The fixing assembly includes a screw rod installed on the mounting plate, and the external thread of the screw rod is connected to a nut, and the external rotating sleeve of the screw rod is provided with a gasket. When installing the clamp, it is necessary to first place the lower end of the screw rod into the groove inside the mounting platform, and then clamp the upper end of the screw rod into the groove on the mounting plate, and then install the gasket and nut on the screw rod in turn, and finally tighten the nut at each location, so that the clamp can be stably fixed on the upper end of the mounting platform.

[0015] (3) There are two threads in opposite directions symmetrically distributed on the threaded rod, and one end of the threaded rod is fixedly connected with a hexagonal nut. When fixing the part, the nut at one end of the threaded rod is turned by a wrench, which drives the threaded rod to start rotating. The connecting block starts to move closer because of the two threads in opposite directions on the threaded rod, and finally the part can be stably fixed on the fixture.

[0016] (4) The outer wall of the upper end of the gathering plate is designed to be evenly concave downward, and a rectangular opening connected to the protection box is opened at the upper end of the gathering plate. When the waste chips generated during the processing begin to enter the gathering plate from the feeding plate, the concave design of the surface of the gathering plate allows the waste chips to quickly enter the vibration plate from the opening on the gathering plate, thereby improving the efficiency of the waste chip collection work.

[0017] (5) There are multiple filter holes evenly arranged on the vibration plate, and the vibration plate is placed obliquely inside the protective box. When waste chips enter the upper end of the vibration plate, the filter holes on the vibration plate can filter out some cutting fluid mixed in the waste chips. The remaining waste chips will be discharged from the discharge port along with the vibration of the vibration plate. The obliquely placed vibration plate can prevent waste chips from remaining on the vibration plate.

[0018] (6) The spring sheet is made of stainless steel, and the upper and lower ends of the spring sheet are fixed to the lower end of the vibration plate and the inner wall of the protection box respectively by screws and connecting blocks. When the vibration plate vibrates, the four groups of spring sheets will be deformed. At this time, the spring sheet can avoid loosening under the action of the screws, thus ensuring the normal vibration process of the vibration plate. BRIEF DESCRIPTION OF THE DRAWINGS
