[0002] A machine tool refers to a machine that manufactures machines, also known as a mother machine or a tool machine, and is commonly referred to as a machine tool for short. It is generally divided into metal cutting machine tools, forging machines, and woodworking machine tools, etc. There are many methods for machining mechanical parts in modern mechanical manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, for parts with relatively high precision requirements and relatively fine surface roughness requirements, they generally need to be finally processed by cutting methods on machine tools;

[0003] A metal processing machine tool with the publication number of CN220921707U belongs to the technical field of metal processing. There are two vibration damping mechanisms on the bottom plate. The two vibration damping mechanisms are fixedly connected to the top plate. The vibration damping mechanism is slidably connected to the second slide bar. The second slide bar is fixedly connected to the top plate. The top plate is fixedly connected to the fixed seat. A plurality of clamping heads are installed on the fixed seat. A processing mechanism is arranged on the top plate. The processing mechanism corresponds to the plurality of clamping heads. The processing mechanism is threadedly connected to the second threaded rod. The second threaded rod is rotatably connected to the fixed seat. The second threaded rod is fixedly connected to the second motor. The second motor is fixedly connected to the baffle. The baffle is fixed on the top plate. A cooling mechanism is arranged on the top plate. The nozzle of the cooling mechanism is arranged above the plurality of clamping heads. The metal processing machine tool of the present invention can achieve precise processing and efficient cooling of metal workpieces, and at the same time reduce the influence of vibration on the machine tool and metal workpieces, and improve the processing quality.

[0004] The utility model with the publication number of CN201618987U belongs to the technical field of fan equipment accessories, and discloses a processing and positioning machine tool for a fan bearing box body. The main technical features include: a processing machine tool provided with a flat workbench, and one or two fixing pins in the shape of a multi-sided column or a multi-sided column structure are arranged on the flat workbench. When using the machine tool to process the fan bearing box body, the corresponding holes arranged on the bottom surface of the fan bearing box body are clamped into the fixing pins for fixation, so as to effectively prevent the bearing box body from shifting during processing and affecting the processing accuracy.

[0005] The utility model with the publication number CN219444409U provides a processing machine tool for stainless steel boxes, which includes a machine tool and a box body. The box body is fixedly connected above the machine tool. The box body includes an opening and closing door assembly and a cleaning assembly. The opening and closing door assembly is located on one side of the box body, and the cleaning assembly is located inside the box body. The utility model relates to the field of processing equipment. When machining parts, the opening and closing door below is driven by a linkage rod. After opening the opening and closing door, the blade device is sent into the interior of the box body. Then the opening and closing door is closed again. The blade device can control its orientation through the first movable rod and the lower movable assembly. Subsequently, the motor is turned on to drive the fan to rotate, blowing the debris generated during the processing into the leakage pipe, and then entering the collection box below through the leakage pipe. The advantage of the processing machine tool for stainless steel boxes provided by the utility model is that it can directly clean and collect the debris generated during processing, saving working time to a certain extent.

[0006] During the process of the processing machine tool machining the box body, most metal box bodies are fixedly placed to increase the stability of the metal box body. However, after being fixed, it is not convenient to adjust the angle of the metal box body, and it is not convenient to machine the metal box body from multiple angles. Therefore, the present invention proposes a processing machine tool for metal box bodies to solve the above problems. Summary of the Invention

[0007] Based on the technical problem in the background art that most metal box bodies are fixedly placed to increase the stability of the metal box body, but after being fixed, it is not convenient to adjust the angle of the metal box body, and it is not convenient to machine the metal box body from multiple angles, the present invention proposes a processing machine tool for metal box bodies.

[0008] A processing machine tool for metal box bodies proposed by the present invention includes a base. A gantry crane is installed on the top of the base. A processing device is installed at the bottom of the gantry crane. Electric push rods arranged in a matrix are fixedly installed on the top of the base. The number of electric push rods is four.

The number of both the clamping mechanisms and the fixing mechanisms is two groups. The clamping mechanisms cooperate with the metal box body and the fixing mechanisms respectively. Horizontal rotation mechanisms and vertical rotation mechanisms are respectively provided on the top of the base. The number of the vertical rotation mechanisms is two groups. The vertical rotation mechanisms cooperate with the horizontal rotation mechanisms and the electric push rods respectively.

[0010] By means of the above mechanism: by placing the metal box inside the mounting circular frame, the metal box can be clamped and fixed using two fitting plates, preventing the metal box from shaking and increasing the stability during processing. Starting the electric push rod can adjust the height of the metal box, starting the first motor can adjust the vertical angle of the metal box, and starting the second motor can adjust the horizontal angle of the metal box, facilitating multi-angle processing of the metal box.

[0011] Preferably, the vertical rotation mechanism includes: an L-shaped mounting frame, a first motor, a driving rectangular frame, and a mounting circular frame;

[0012] Two L-shaped mounting frames are respectively fixedly connected to the output shafts of the four electric push rods.

The mounting circular frame is rotationally connected to the driving rectangular frame.

[0013] Furthermore, after the first motor is started, the first motor can drive the driving rectangular frame to rotate vertically, so that the driving rectangular frame can drive the mounting circular frame to rotate vertically, and the mounting circular frame can drive the metal box to rotate vertically, realizing the adjustment of the vertical angle of the metal box.

[0014] Preferably, the horizontal rotation mechanism includes: a toothed ring, a second motor, a gear, and a motor frame;

[0022] Further, after the positioning frame engages with the fixing sleeve, the positioning frame can connect the fixing sleeve and the control frame to block the rotation of the control frame and the driving disk on the fixing sleeve. The driving disk can block the rotation of the threaded rod, so that the threaded rod can be positioned, and the fitting plate can stably clamp the metal box body, so that the threaded rod will not rotate due to external vibration, preventing the fitting plate from releasing the metal box body. After the control block is pushed, the control block can pull the pulling rod, and the pulling rod then pulls the positioning frame to move upward, so that the positioning frame can disengage from the fixing sleeve, realizing the unlocking of the control frame, and enabling the control frame to drive the driving disk to rotate.

[0032] 3. After the threaded rod is driven to rotate, the threaded rod can rotate inside the threaded sleeve and cooperate with the thread inside the threaded sleeve. The threaded rod can push the fitting plate closer to the metal box body and fit with the metal box body, and the two fitting plates can clamp the metal box body;

[0033] 4. After the positioning frame meshes with the fixed sleeve, the positioning frame can connect the fixed sleeve and the control frame to block the rotation of the control frame and the driving disc on the fixed sleeve.
