Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a CNC machine tool assembly line machining system. Background Technology

[0002] Machine tools are a general term for mechanical processing equipment. CNC machine tools have a higher level of automation, saving manual labor and improving efficiency. A Chinese invention patent with publication number CN112935908B discloses a CNC machine tool, including a machine tool body, a mesh door, a reinforcing plate, a machine tool door, a control panel, a track plate, a processor, a fixed table, and a protective mechanism. The protective mechanism uses vibration intervals and cancellation to prevent the processing processor from generating vibrations that cause processing debris to fly. The flying debris impacts the internal components, thus protecting the internal components and ensuring the safety of the equipment components. Another Chinese invention patent with publication number CN102452015A discloses a CNC machine tool, including an outer cover and a protective door. The strip groove on the protective door functions as a handle. Compared with existing handles, it is integrally formed with the protective door, making it less prone to damage, and also has the function of reinforcing ribs, making the entire protective door structure more robust. The groove below the protective door can catch waste chips and coolant flowing down the protective door, preventing them from polluting the ground and making it more hygienic.

[0003] However, the inventors discovered that in actual use, after a single machine tool finishes processing, the workpiece needs to be transported to the next workstation for secondary processing. The process is cumbersome, the work efficiency is low, and the manual placement of parts is not precise enough, resulting in a low product qualification rate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by using a lifting component to drive a rotating component to perform lifting and lowering movements, which in turn drives a clamping component to perform lifting and lowering movements to clamp the parts. The rotating component then moves the parts to the next workstation for further processing. This solves the problems of needing to transport the workpiece to the next workstation for secondary processing after the completion of processing on a single machine tool, which is a cumbersome process with low work efficiency. Furthermore, the manual placement of parts is not precise enough, resulting in a low product qualification rate.

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0006] A CNC machine tool assembly line machining system includes machine tool a, machine tool b, machine tool c, and machine tool d. Machine tool a and machine tool d are each equipped with a lifting assembly. The lower end of the lifting assembly is equipped with a rotary assembly. The rotary assembly is equipped with a plurality of clamping assemblies. Machine tool b and machine tool c are each equipped with a fixing assembly. The lifting assembly drives the rotary assembly to perform lifting and lowering movements, which in turn drives the clamping assemblies to perform lifting and lowering movements to clamp the parts. The rotary assembly then moves the parts to the next workstation for processing.

[0007] As a preferred embodiment, the lifting assembly includes a cylinder mounted on machine tool a or machine tool d, and a piston rod a driven by the cylinder.

[0008] As a preferred embodiment, the rotary assembly includes a guide rail disposed at the lower end of the piston rod a, a drive component disposed on the guide rail, a gear a driven by the drive component, a gear b disposed at the other end of the guide rail, and a chain disposed between gear a and gear b.

[0009] As a preferred embodiment, the clamping assembly includes a support member disposed on the chain, an inclined block slidably disposed within the support member, and a clamping block slidably disposed within the support member.

[0010] As a preferred embodiment, a return spring is provided between the inclined block and the support member, a sliding cavity is provided inside the support member, a groove is provided at the upper end of the sliding cavity for the clamping block to slide, and a spring is provided between the inclined block and the clamping block.

[0011] As a preferred embodiment, the fixing assembly includes a cylinder mounted on machine tool b or machine tool c, a piston rod b driven by the cylinder, and a clamping block mounted on the upper end of the piston rod b.

[0012] As a preferred embodiment, both machine tool a and machine tool d are provided with a placement platform.

[0013] As another preferred embodiment, both machine tool b and machine tool c are equipped with a moving platform and a processing table.

[0014] The beneficial effects of this invention are:

[0015] 1. In this invention, the lifting component drives the rotating component to perform lifting and lowering movements, the rotating component drives the clamping component to perform lifting and lowering movements to clamp the parts, and the rotating component drives the parts to the next work station for processing, which improves work efficiency, eliminates the need for manual loading and unloading of parts, and improves the product qualification rate.

[0016] In summary, this equipment has advantages that make it particularly suitable for the field of CNC machine tool technology. Attached Figure Description

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figures 1 to 6 As shown, a CNC machine tool assembly line machining system includes machine tool a1, machine tool b2, machine tool c3, and machine tool d4. Machine tool a1 and machine tool d4 are each equipped with a lifting assembly 5. A rotary assembly 6 is located at the lower end of the lifting assembly 5. The rotary assembly 6 is equipped with several clamping assemblies 7. Machine tool b2 and machine tool c3 are each equipped with a fixing assembly 8. The lifting assembly 5 drives the rotary assembly 6 to perform lifting and lowering movements, which in turn drives the clamping assemblies 7 to perform lifting and lowering movements to clamp parts 9. The rotary assembly 6 then moves the parts 9 to the next workstation for processing.

[0028] It is worth mentioning that the lifting component 5 drives the rotating component 6 to perform lifting and lowering movements, and the rotating component 6 drives the clamping component 7 to perform lifting and lowering movements to clamp the part 9. The rotating component 6 then drives the part 9 to the next work station for processing, which improves work efficiency, eliminates the need for manual loading and unloading of parts, and increases the product qualification rate.

[0029] like Figure 2 As shown, the lifting assembly 5 includes a cylinder 51 mounted on machine tool a1 or machine tool d4 and a piston rod a 52 driven by the cylinder 51.

[0030] like Figure 4 As shown, the rotary assembly 6 includes a guide rail 61 disposed at the lower end of the piston rod a 52, a drive member 62 disposed on the guide rail 61, a gear a 63 driven by the drive member 62, a gear b 64 disposed at the other end of the guide rail 61, and a chain 65 disposed between the gear a 63 and the gear b 64.

[0031] like Figure 3 As shown, the clamping assembly 7 includes a support member 71 disposed on the chain 65, an inclined block 72 slidably disposed within the support member 71, and a clamping block 73 slidably disposed within the support member 71.

[0032] In this example, part 9 is clamped by clamping block 73 and inclined block 72.

[0033] like Figure 5 As shown, a return spring 74 is provided between the inclined block 72 and the support member 71. A sliding cavity 75 is provided in the support member 71. A sliding groove 76 for the clamping block 73 to slide is provided at the upper end of the sliding cavity 75. A spring 77 is provided between the inclined block 72 and the clamping block 73.

[0034] In this example, the reset is achieved by pressing the inclined block 72 in through the reset spring 74, and the reset is achieved by sliding the clamping block 73 through the spring 77.

[0035] like Figure 3 As shown, the fixing assembly 8 includes a cylinder 81 mounted on machine tool b2 or machine tool c3, a piston rod b 82 driven by the cylinder 81, and a clamping block 83 mounted on the upper end of the piston rod b 82.

[0036] like Figure 2 As shown, both machine tool a1 and machine tool d4 are equipped with a placement table 11.

[0037] like Figure 2 , 3 As shown, both machine tool b2 and machine tool c3 are equipped with a moving platform 21 and a processing table 22.

[0038] The work process is as follows:

[0039] The robotic arm places part 9 on the placement table 11 of machine tool a1, and cylinder 51 drives piston rod a 52 to descend, thereby driving rotary assembly 6 to descend.

[0040] The inclined block 72 is pressed against the outside of part 9 and slides into the sliding cavity 75, which drives the clamping block 73 to slide on the slide groove 76 and slide into the sliding cavity 75 together with the inclined block 72. At this time, the return spring 74 is compressed and the spring 77 is stretched. When the inclined block 72 passes over part 9, the upper end face of the inclined block 72 contacts part 9 and rebounds under the action of the return spring 74. The clamping block 73 also rebounds under the action of the spring 77, clamping part 9.

[0041] The cylinder 51 drives the piston rod a 52 to rise, which in turn drives the rotary assembly 6 to rise, thereby driving the part 9 to rise. The drive component 62 drives the gear a 63 to rotate, thereby driving the chain 65 to rotate. The chain 65 drives the clamping assembly 7 and the part 9 to enter the next station, repeating this process to achieve assembly line processing.

[0042] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
