DETAILED DESCRIPTION

[0021] The following will be described in detail in combination with the accompanying drawings. Figures 1-4 The utility model will be described in further detail.

[0022] Embodiment one, refer to Figures 1-4 In the present embodiment, in order to solve the two major problems existing in the actual operation of the numerical control machining lathe for automobile parts at present, in the machining link, the staff needs to control multiple sets of equipment to complete the fastening and limiting operation of the automobile parts, not only consumes a lot of manpower and time cost, but also the operation process is relatively complicated, and after the machining is completed, the problem of inconvenient unloading seriously affects the overall machining efficiency, the utility model discloses a numerical control machining lathe for automobile parts,

[0023] The lathe body 1 is provided with the air cylinder 2 fixedly arranged at the top, three support seats 3 are distributed in sequence clockwise at the outer side of the air cylinder 2 with an interval of 90°, the three support seats 3 are all fixedly arranged at the top of the lathe body 1, and the top of each of the three support seats 3 is provided with a positioning assembly;

[0024] The positioning assembly comprises an L-shaped movable plate 4, the movable plate 4 is movably hinged to the top of the support seat 3, a placing table 5 is arranged above the air cylinder 2, the placing table 5 is located between the three movable plates 4, each movable plate 4 is provided with a fastening assembly on the side close to the placing table 5, a drive shaft 6 is fixedly connected to the top output end of the air cylinder 2, a connecting plate 7 is fixedly installed at the top of the drive shaft 6, three first connecting blocks 8 are distributed in sequence clockwise at the outer side of the connecting plate 7 with an interval of 90°, each movable plate 4 is fixedly provided with a second connecting block 9 on one end close to the adjacent first connecting block 8, and each second connecting block 9 and the adjacent first connecting block 8 are movably hinged through a connecting rod 24, a support rod 10 is further fixedly arranged at the top of the connecting plate 7, an opening 11 is formed in the inside of the placing table 5, and a lifting table 12 is arranged on the upper surface of the placing table 5, and the top end of the support rod 10 is fixedly connected to the bottom of the lifting table 12 through the opening 11;

[0025] Specifically, the movable plate 4 rotates around the hinge point at the top of the support base 3. With this structure, the movable plate 4 can be flexibly adjusted in position to meet the positioning needs of different sizes of automobile parts placed on the placement table 5. When the cylinder 2 operates, the drive shaft 6 and the connecting plate 7 move, driving the first connecting block 8 to move. With the connecting rod 24, the movement of the first connecting block 8 can be accurately transmitted to the second connecting block 9, thereby effectively controlling the rotation angle of the movable plate 4.

[0026] The fastening assembly includes a plurality of positioning rods 13, each of which is sequentially arranged on the surface of the movable plate 4 along the axial direction of the movable plate 4, and each of which is fixedly provided with a positioning block 14 at the end close to the placement table 5.

[0027] Specifically, the plurality of positioning rods 13 can be flexibly moved on the surface of the movable plate 4 along the axial direction of the movable plate 4. When the automobile parts are placed on the placement table 5, the positioning block 14 can be in close contact with the surface of the parts. In this way, not only can the parts be accurately positioned, but also a preliminary fastening effect can be achieved, effectively preventing the parts from shifting during processing.

[0028] Each positioning rod 13 is externally sleeved with a telescopic spring 15, each telescopic spring 15 is located between the positioning block 14 and the movable plate 4, and each positioning rod 13 is fixedly provided with a limiting plate 16 at the end away from the placement table 5.

[0029] Specifically, the telescopic spring 15 is sleeved outside the positioning rod 13. When the positioning block 14 contacts the automobile parts and is subjected to pressure, the telescopic spring 15 will elastically deform, thereby generating a corresponding elastic force. This elastic force causes the positioning block 14 to always maintain close contact with the surface of the parts, achieving stable fastening of the parts. The limiting plate 16 functions to limit the movement range of the positioning rod 13, preventing the positioning rod 13 from detaching from the movable plate 4.

[0030] The lathe body 1 is fixedly provided with a fixed seat 17 at the top, and the placement table 5 is fixedly installed on the front side of the fixed seat 17. The fixed seat 17 is internally provided with a dust removal assembly.

[0031] Specifically, the fixed seat 17 not only provides stable support for the placement table 5, but also provides convenient conditions for the installation and operation of the dust removal assembly. The placement groove 20 provides installation space for the dust removal pipe 21, ensuring that the dust removal pipe 21 can be smoothly connected to the suction head 18 to achieve dust collection and discharge.

[0032] The dust removal assembly includes several suction heads 18. The fixed base 17 has a movable groove 19 inside, and the movable groove 19 is located directly behind the placement platform 5. Each suction head 18 is fixedly installed on the inner wall of the rear side of the movable groove 19 from left to right. The fixed base 17 also has a placement groove 20 inside on the left side. A dust discharge pipe 21 is fixedly installed on the top inner wall of the placement groove 20, and each suction head 18 is connected to the dust discharge pipe 21. A collection box 23 is inserted inside the placement groove 20, and the collection box 23 is located directly below the bottom of the dust discharge pipe 21.

[0033] Specifically, a placement slot 20 is provided inside the left side of the mounting base 17. The dust exhaust pipe 21 is securely installed on the top inner wall of the placement slot 20 and connected via an internal pipe, allowing it to communicate with the internal space of each vacuum head 18. Through this connection, dust and debris sucked in by the vacuum head 18 can be smoothly discharged through the dust exhaust pipe 21. The collection box 23 adopts a plug-in design, allowing for easy insertion into the placement slot 20, and its position is directly below the bottom of the dust exhaust pipe 21, facilitating the collection of dust and debris discharged from the dust exhaust pipe 21, achieving centralized dust collection and cleaning.

[0034] A control unit 22 is fixedly installed on the top of the lathe body 1, and the control unit 22 is located on the right side of the placement table 5;

[0035] Specifically, a control unit 22 is mounted on the top of the lathe body 1, located on the right side of the platform 5. The control unit 22 is connected to the various functional modules of the lathe body 1 via a pre-set circuit. Operators can set parameters on the control unit 22, precisely controlling key parameters such as the lathe's rotational speed, depth of cut, and feed rate to ensure the lathe can complete various complex machining tasks. Simultaneously, the control unit 22 is equipped with a visual display screen that provides real-time feedback on the lathe's operating status, including important information such as machining progress and tool wear, greatly improving operational convenience and machining safety.

[0036] The specific working principle is: the staff first places the parts to be processed on the lifting table 12 of the placing table 5. By controlling the machine body 22, the air cylinder 2 is started. The output end of the air cylinder 2 drives the driving shaft 6 to move upward, and the driving shaft 6 drives the connecting plate 7 to move upward synchronously. With the upward movement of the connecting plate 7, the first connecting block 8 distributed on the outer side of the connecting plate 7 also moves. Since the first connecting block 8 is movably hinged with the second connecting block 9 on the movable plate 4 through the connecting rod 24, the upward movement of the first connecting block 8 is transmitted to the second connecting block 9 through the connecting rod 24, and then drives the movable plate 4 to rotate outward with the hinge point at the top of the supporting seat 3 as the axis. In the process of rotating the movable plate 4, the staff pre-sets parameters through the control machine body 22, so that the movable plate 4 is rotated to the appropriate position to adapt to the positioning needs of automobile parts of different sizes. When the movable plate 4 reaches the predetermined position, the side surface of the automobile parts placed on the placing table 5 will be in contact with the positioning block 14 of the fastening assembly. The plurality of positioning rods 13 are flexibly movable along the axial direction on the surface of the movable plate 4, the positioning block 14 is tightly attached to the surface of the parts, and the parts are preliminarily positioned and fastened. At the same time, the extension spring 15 outside the positioning rod 13 is elastically deformed due to the pressure, and the elastic force is generated, so that the positioning block 14 is always tightly attached to the surface of the parts, and the fastening effect is further enhanced, so that the displacement of the parts during the machining process is prevented. In the machining process, the dust removal assembly works synchronously. When the lathe performs cutting operation to generate dust and debris, the dust and debris are sucked into the dust suction head 18. Since the dust suction head 18 is in communication with the dust exhaust pipe 21 inside, the dust and debris are guided into the collection box 23 in the placing groove 20 through the dust exhaust pipe 21, so that the dust generated in the machining process is collected, the working environment is kept clean, and the staff can monitor the running state of the lathe in real time through the control machine body 22, such as the machining progress, the tool wear condition and the like, and adjusts the key parameters such as the rotating speed, the cutting depth, the feeding speed and the like of the lathe according to the actual machining needs. When the machining is completed, the air cylinder 2 is controlled in reverse by the control machine body 22, the driving shaft 6 and the connecting plate 7 are lowered, the first connecting block 8 drives the movable plate 4 to rotate inward, and the fastening of the automobile parts is released. At the same time, the staff can operate the lifting table 12 to rise through the control machine body 22, so that the machined parts are lifted, and the unloading is facilitated. After the unloading is completed, the collection box 23 can be pulled out from the placing groove 20, and the collected dust and debris are cleaned, so as to prepare for the next machining.

[0037] The wiring diagram of the air cylinder in the utility model belongs to the common knowledge in the field, and its working principle is a known technology. The model is selected according to the actual use, so the control mode and the wiring arrangement of the air cylinder are not explained in detail.

[0038] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
