[0001] The utility model belongs to the technical field of machine tools, in particular to a mobile mechanical processing machine tool. Background Art

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

[0003] Publication number "CN116586983A" discloses "a mechanical processing machine tool" that fixes and rotates a tubular workpiece through a clamping structure, making it convenient to perform laser welding on the tubular workpiece. After welding, the welds at the joints of the tubular workpiece can be polished through a grinding ring, thereby improving welding and polishing efficiency.

[0004] At the same time, the publication number "CN219787603U" discloses "a machine tool for mechanical processing". By setting an induced draft fan, a first ventilation hose, a second ventilation rigid pipe, a horizontal ventilation rigid pipe, a blowing nozzle, a dust hood, a collection box, a filter mesh plate, a third ventilation rigid pipe, a second ventilation hose, a fourth ventilation rigid pipe, a first electric telescopic rod and a second electric telescopic rod, the waste chips accumulated on the surface of the machine tool body can be conveniently and fully cleaned and collected, and the waste chip cleaning operation can also be performed on different areas of the surface of the machine tool body, thereby improving the waste chip processing efficiency of the machine tool for mechanical processing.

[0005] The above technical solutions all have the following disadvantages during implementation:

[0006] There is a lack of corresponding moving mechanisms. When the machine tool is transported and moved, it needs to be transported with the help of lifting equipment or manual labor. Since the machine tool itself is large in size and heavy, the cost of transporting the machine tool is high and troublesome. The machine tool cannot be moved quickly, making the movement of the machine tool inconvenient.

[0007] In view of the above problems, we propose a mobile machining machine tool. Utility Model Content

[0029] The arc-shaped rubber block 12 is convenient for limiting the universal wheel 3. Combined with the elastic effect of the first spring 10 and the sliding cooperation between the strip plate 9 and the guide rod 8, it is convenient to squeeze the strip plate 9 downward. Under the action of the fixing rod 11, the rubber block 12 is in contact with the ground, which increases the friction between the machine tool body 1 and the ground, and further ensures the stability of the machine tool body 1 during use. The threaded cooperation between the screw rod 4 and the movable plate 5 facilitates the upward adjustment of the movable plate 5. Combined with the hinged effect at both ends of the connecting arm 6 and the connection between the movable frame 7 and the U-shaped block, The rotation cooperation makes it easy to drive the movable frame 7 to flip in the direction of the screw rod 4. With the cooperation of the strip plate 9 and the fixed rod 11, it is easy to drive the rubber block 12 to move away from the universal wheel 3 and the ground. Under the action of the universal wheel 3, it is convenient to move the machine tool body 1, which solves the problem of lack of corresponding moving mechanism in the prior art. When the machine tool is transported and moved, it needs to be transported with the help of lifting equipment or manual labor. Since the machine tool itself is large in size and heavy, the cost of transporting and moving the machine tool is high and it is more troublesome. This facilitates the transportation and movement of the machine tool.

[0030] The reset assembly includes a reset plate 14, a reset spring 15, a connecting rope 16, a pulley block 17 and a support rod 18. Two movable grooves 13 are relatively opened on the lower end surface of the base 2. The two movable grooves 13 are respectively arranged on the left and right sides of the groove. The reset plate 14 is movably arranged inside the movable groove 13. The reset spring 15 is arranged on the side of the reset plate 14 away from the groove, and the two ends of the reset spring 15 are respectively fixedly connected to the reset plate 14 and the inner wall of the movable groove 13. A circular hole penetrates between the movable groove 13 and the groove. The two pulley blocks 17 are relatively arranged on the inner side of the groove. One end of the connecting rope 16 is fixedly connected to the reset plate 14, and the other end passes through the circular hole and the pulley block 17 and is fixedly connected to the movable frame 7. The two support rods 18 are relatively fixed on the upper and lower sides of the movable groove 13, and the support rod 18 penetrates the reset plate 14, and the reset plate 14 and the support rod 18 are slidably matched.

[0031] Through the elastic action of the reset spring 15, combined with the connecting rope 16, and the sliding cooperation between the reset plate 14 and the support rod 18, it is convenient to assist the movable frame 7 to flip inward during the process of adjusting the movable plate 5 to move upward, thereby ensuring the stability of the movement of the movable frame 7. The pulley block 17 effectively limits and guides the connecting rope 16, thereby ensuring the pulling effect of the connecting rope 16 on the movable frame 7.

[0032] The reinforcement structure includes a sleeve 19, a second spring 20, an extrusion rod 21 and a rubber sheet 22. The two sleeves 19 are relatively fixed on the lower surface of the movable plate 5. The extrusion rod 21 is movably matched with the inner cavity of the sleeve 19. The second spring 20 is connected between the upper end of the extrusion rod 21 and the inner wall of the sleeve 19. The rubber sheet 22 is fixed to the lower end of the extrusion rod 21. Through the elastic action of the second spring 20 and the active cooperation between the extrusion rod 21 and the sleeve 19, it is convenient to squeeze the rubber sheet 22 downward so that the rubber sheet 22 is against the ground, which further increases the friction between the bottom of the machine tool and the ground, thereby ensuring the stability of the machine tool body 1.

[0033] A servo motor 23 is installed on the upper side of the support frame, and the output shaft of the servo motor 23 is connected to the upper end of the screw rod 4. Two limit rods 24 are relatively fixed inside the support frame. The limit rods 24 pass through the movable plate 5, and the movable plate 5 and the limit rods 24 are slidably matched.

[0034] The first spring 10 is sleeved on the outside of the guide rod 8 , and the return spring 15 is arranged between two adjacent support rods 18 .

[0035] Example:

[0036] In the initial state, the movable plate 5 is at the uppermost side, the rubber plate 22 and the rubber block 12 are not in contact with the ground, and the machine tool body 1 is transported and moved under the action of the universal wheel 3;

[0037] After the machine tool body 1 is moved to a suitable position, when the machine tool body 1 needs to be fixed, the servo motor 23 is first started, and the screw rod 4 is driven to rotate by the servo motor 23. Under the thread cooperation between the movable plate 5 and the screw rod 4, and the sliding cooperation between the movable plate 5 and the limit rod 24, the movable plate 5 is driven to move downward stably. Through the downward movement of the movable plate 5, under the hinged action at both ends of the connecting arm 6, combined with the rotation cooperation between the movable frame 7 and the U-shaped block, the movable frames 7 on both sides are turned over in the direction away from the screw rod 4 with the rotating shaft as the center;

[0038] As the movable plate 5 moves downward, the rubber plate 22 first contacts the ground, and under the cooperation of the extrusion rod 21 and the sleeve 19, and the elastic action of the second spring 20, the movable plate 5 continues to move downward, driving the movable frame 7 to continue to flip, until the movable frame 7 flips to a vertical state, at which time the arc-shaped rubber block 12 is driven to get stuck on one side of the universal wheel 3, limiting the universal wheel 3, and stopping the operation of the servo motor 23;

[0039] Under the elastic action of the first spring 10, the strip plate 9 is squeezed downward, and combined with the fixing rod 11, the rubber block 12 is stuck on one side of the universal wheel 3 and against the ground. Under the elastic action of the second spring 20, the rubber plate 22 is tightly attached to the ground, which effectively increases the friction between the bottom of the machine tool and the ground, ensures the stability of the machine tool body 1 during use, and facilitates the use of the machine tool body 1.

[0040] In the process of the movable frame 7 turning outward, the connection rope 16 is combined to pull the reset plate 14 to move in the direction of the pulley block 17, and the reset spring 15 is stretched;

[0041] In the subsequent use process, when the machine tool body 1 needs to be transported and moved, the servo motor 23 is started to rotate in the opposite direction, and the movable plate 5 is driven to move upward stably under the cooperation of the screw rod 4 and the limit rod 24;

[0042] By moving the movable plate 5 upwards, combined with the connecting arm 6, the movable end of the movable frame 7 is driven to move in the direction close to the screw rod 4. At the same time, under the elastic action of the reset spring 15, the reset plate 14 is driven to move in the direction away from the pulley block 17. Combined with the connecting rope 16, the movable frame 7 is pulled, and the auxiliary movable frame 7 is flipped in the direction close to the screw rod 4 with the rotating shaft as the center, until the rubber block 12 is driven away from the universal wheel 3 and the ground. At the same time, as the movable plate 5 moves upwards, the rubber plate 22 is driven upwards away from the ground, so that at the bottom of the machine tool body 1, only the universal wheel 3 is in contact with the ground, and then the machine tool body 1 is moved by the universal wheel 3, which solves the problem of lack of corresponding moving mechanism in the prior art. When the machine tool is transported and moved, it needs to be transported with the help of lifting equipment or manual labor, resulting in a large cost and more troublesome disadvantages of transporting and moving the machine tool, and facilitates the transport, movement and fixation of the machine tool.

[0043] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the servo motor 23 in the utility model is purchased on the market, and technical personnel in this field can install and use it according to requirements.
