[0034] Reference Figure 1-Figure 9 A flexible clamping automobile parts processing device comprises a mounting plate 1, a movable supporting plate 2 is mounted on the top of the mounting plate 1, a rubber clamping block 3 is arranged on one side of the supporting plate 2, a driving part 4 is arranged on the other side of the supporting plate 2, a clamping assembly 5 arranged on the supporting plate 2, one end of which is connected to the rubber clamping block 3 and is used to clamp and fix the workpiece; a cleaning assembly 6 is arranged on the clamping assembly 5, which is used to back-blow and clean the adjusting active part when the clamping assembly 5 is in an adaptive adjustment state; a blocking assembly 7 is arranged in the clamping assembly 5, which blocks and protects the active part after the clamping assembly 5 adaptively adjusts the clamping limit, the driving part 4 is fixed on a mounting block 41 on one side of the supporting plate 2, an electric push rod 42 is mounted on one end of the mounting block 41, and a mounting frame 43 fixed on the mounting plate 1 is mounted on the electric push rod 42.

[0035] In the present invention, the device is pre-installed on the machine tool when in use, and then the craftsman is placed between the two support plates 2, and the driving part 4 is used to drive the support plates 2 to move relatively, so that the rubber clamping block 3 clamps and limits the workpiece in the middle. Considering that in actual use, the shapes of automobile parts are diverse, and some workpieces with special shapes are not convenient to clamp and limit during processing, therefore, in this solution, through the provided clamping assembly 5, the positions of multiple rubber clamping blocks 3 can be adjusted according to the shape of the workpiece to be processed, so as to better adapt to the outer wall shape of the workpiece and fit it therewith, so as to better clamp and limit, and avoid the uneven clamping force under the traditional method, easy displacement, and poor clamping effect. At the same time, the rubber clamping block 3 is made of rubber material, which has a good protective effect on some workpiece products that are easy to break. Compared with the traditional clamping mechanism, it has a wider range of applications. In this scheme, when the clamping component 5 is adaptively adjusting the clamping of the workpiece, the cleaning component 6 is driven by the clamping component 5 to run synchronously to generate airflow and then transport it to the adjustable active part of the clamping component 5. The gap in the active part can be cleaned to avoid dust and debris splashed during the previous processing from being stuck inside, causing blockage and jamming, affecting the adjustment operation of the structure, reducing the occurrence of faults, and saving maintenance costs. At the same time, when the cleaning component 6 is running, part of the airflow can be transported to the sealing component 7, so that the clamping component 5 is unblocked when the workpiece is adaptively clamped. Then, after the adaptive adjustment is completed, the active adjustment part of the clamping component 5 is blocked again to avoid foreign matter from entering the installation box 52, avoid the accumulation of dust and foreign matter, and improve the smoothness of the structure operation.

[0036] In a preferred embodiment, referring to Figure 5 The clamping assembly 5 includes an adjusting rod 51 fixed to one side of the rubber clamping block 3, and multiple adjusting rods 51 are slidably connected in the installation box 52. One side of the installation box 52 is fixedly connected to the support plate 2. A first piston 54 is fixed at the end of the adjusting rod 51. The first piston 54 is slidably connected in the connecting cylinder 53. The connecting cylinder 53 is installed on the inner wall of the installation box 52. An extrusion spring 55 is fixed between the first piston 54 and the connecting cylinder 53. An exhaust pipe 56 is provided at one end of the connecting cylinder 53. An intake pipe 10 is fixed to one side of the installation box 52. A one-way valve is provided on the intake pipe 10. One end of the intake pipe 10 is connected to the air collecting chamber 61.

[0037] The above scheme is adopted, wherein a plurality of adjusting rods 51 distributed at equal intervals are provided on the mounting box 52, one end of which is connected to the rubber clamping block 3, and the rubber clamping block 3 is distributed on one side surface of the mounting box 52, thereby increasing the clamping area of ​​the device for the workpiece. When there is a protrusion on the outer surface of the workpiece, the rubber clamping block 3 is squeezed so that the first piston 54 at the end of the adjusting rod 51 slides inside the connecting tube 53, so that the rubber clamping block 3 can better fit and contact the outer wall of the clamped workpiece for limiting the position. As the two support plates 2 move relative to each other, the workpiece is clamped and limited. This design method is suitable for clamping operations of different automotive parts, and effectively improves the flexibility and application range of the clamp.

[0038] In a preferred embodiment, referring to Figure 5 and Figure 6 The cleaning component 6 includes an air collecting cavity 61 formed on the inner wall of the installation box 52, the exhaust pipe 56 is connected to the air collecting cavity 61, an air supply pipe 62 connected to the air collecting cavity 61 is provided on the top of the installation box 52, a first valve 63 is provided at the connection between the air supply pipe 62 and the installation box 52, one end of the air supply pipe 62 passes through the installation box 52 and extends into the second valve 64, the second valve 64 is provided on the inner wall of the other side of the installation box 52, a second valve 64 is provided at the end of the air supply pipe 62, a cavity 65 is formed on the inner wall of the installation box 52, an exhaust port 66 connected to the cavity 65 is formed on the inner wall of the installation box 52, two groups of exhaust ports 66 are provided, and the exhaust ports 66 are arranged at an inclined angle.

[0039] By adopting the above scheme, when the first piston 54 slides inside the connecting cylinder 53, the air in the rodless cavity in the connecting cylinder 53 is squeezed, and then transported to the inside of the air collecting cavity 61 through the exhaust pipe 56. The airflow concentrated in the air collecting cavity 61 is transported to the inside of the cavity 65 through the air delivery pipe 62, and finally ejected through the exhaust port 66, wherein the exhaust port 66 is provided with two groups, which are annularly distributed around the outside of the adjusting rod 51. When the airflow is ejected from the exhaust port 66, the ejected airflow can back-blow and clean the dust and debris remaining at the connection between the adjusting rod 51 and the mounting box 52, thereby keeping the sliding of the adjusting rod 51 smoother and avoiding jamming. The setting of the two groups of airflows further improves the cleaning effect of the connection between the adjusting rod 51 and the mounting box 52. At the same time, during the airflow blowing process, the airflow can play a certain role in cooling and dissipating heat on the surface of the adjusting rod 51, taking away the heat generated by the frequent sliding of the adjusting rod 51 and the friction between the mounting box 52, thereby extending the service life of the component.

[0040] In a preferred embodiment, referring to Figure 3 , Figure 7 , Figure 8 and Fig. 9The blocking assembly 7 includes a diverter valve 71 installed on the gas delivery pipe 62, an air guide pipe 72 is fixed to one end of the diverter valve 71, the end of the air guide pipe 72 passes through the installation box 52 and extends to the inside where a diverter pipe 73 is fixed, one end of the diverter pipe 73 is connected to a spreader, the spreader includes a sleeve 74 fixed to the end of the diverter pipe 73, the sleeve 74 is slidably connected to the inside of the second piston 75, a moving rod 76 is fixed to one side of the second piston 75, a connecting block 77 is fixed to the end of the moving rod 76, and an adjusting plate 78 is installed on one side of the connecting block 77 An arc block 79 is fixed to the bottom of the adjustment plate 78, a tension spring 791 is fixed between the two adjustment plates 78, a sponge block 792 is installed on one side of the arc block 79, a drainage tube 793 is embedded in the top of the arc block 79, one end of the drainage tube 793 extends into the adjustment plate 78, a storage cavity 794 is provided inside the adjustment plate 78, a liquid inlet pipe 795 is installed on the top of the adjustment plate 78, a slider 8 is fixed to one side of the adjustment plate 78, the slider 8 is slidably connected in the slide groove 9, and the slide groove 9 is opened on the inner wall of the installation box 52.

[0041] With the above solution, after a part of the airflow in the air delivery pipe 62 is diverted, it is transported to the inside of the sleeve 74 through the diverter pipe 73, and then the two adjustment plates 78 are moved in opposite directions by the extrusion of the airflow, so that the two arc blocks 79 are separated from the connection between the adjustment rod 51 and the installation box 52, the blocked state is released, and the adjustment rod 51 is convenient for better sliding. After the clamping assembly 5 adaptively adjusts the clamping state, the airflow entering the sleeve 74 stops. At this time, under the elastic pull of the tension spring 791, the arc block 79 is reset, and the two arc blocks 79 are located in the installation box 52, which is close to the installation box 52. 2 and the adjusting rod 51 are blocked again, so as to prevent debris from running into the interior of the mounting box 52 during the processing of the workpiece, thereby affecting the operation of various components and reducing the occurrence of device failures. A sponge block 792 is provided on one side of the arc block 79 to lubricate the surface of the adjusting rod 51 and reduce the wear caused by the frequent sliding of the adjusting rod 51. The drainage tube 793 is a capillary tube, which can absorb and transport the lubricating liquid in the storage chamber 794 to the sponge block 792, thereby realizing the function of automatically adding lubrication, saving the labor intensity of maintenance personnel, improving work efficiency and reducing maintenance costs.

[0042] It should be noted that the squeezing force generated by the airflow entering the sleeve 74 is greater than the elastic tension of the tension spring 791, so the two arc blocks 79 can be separated during airflow delivery.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
