Clamping devices and machine tools according to some embodiments of the invention are described below with reference to fig. 1 to 4.
Example 1
As shown in fig. 1, the present embodiment provides a clamping device 100 provided on a machine tool 200, including: a clamping assembly 110 and a positioning assembly 120. The clamping assembly 110 is adapted to clamp a part 300 to be machined. The positioning assembly 120 includes a driving portion 122 and a positioning portion 124. The driving portion 122 drives the positioning portion 124 to move forward along the first direction Y, so that the positioning portion 124 stops the to-be-processed member 300, and the driving portion 122 drives the positioning portion 124 to move backward along the first direction Y, so that the positioning portion 124 avoids the to-be-processed member 300.
The machine tool 200 of the present embodiment may be embodied as a numerical control machine tool for cutting a member to be machined 300. The member to be processed 300 has a cylindrical or cylindrical structure. For example, the part 300 to be machined in the present embodiment may be a cylinder of a telescopic arm of a cutting part of a boom-type excavator, which requires machining of an outer circle, an end face and an inner hole of the cylinder during machining, so that the shape, size and precision of the cylinder can meet machining requirements.
The machine tool 200 of the present embodiment is provided with the clamping device 100, and the clamping device 100 is used to clamp and fix the member 300 to be machined so that the cutting tool can perform cutting. The structure and the working mode of the clamping device in the related art are relatively complex, the operation is inconvenient, and the processing efficiency is low.
For example, the clamping device of the related art needs to clamp and process the cylinder barrel of the telescopic arm of the cutting part of the boom-type roadheader in two procedures, the first procedure adopts a three-jaw self-centering chuck to match with an inner hole at one end of a special jaw inner support cylinder barrel, the other end adopts a center frame to carry out auxiliary support, and the end face and the inner hole of the excircle and the tailstock end of the cylinder barrel are subjected to turning processing. The second process is to change the clamping position of the cylinder, and the three-jaw self-centering chuck is matched with the inner hole processed by the special jaw inner support, and the center frame is used for auxiliary support to process the end face and the excircle of the cylinder tailstock end.
For example, the clamping device in the related art can also adopt a clamping jaw outer circle or an inner hole special for a four-jaw independent chuck, and the clamping and the processing are carried out in two procedures in the same way.
In summary, the convenience and efficiency of the clamping device in the related art need to be improved. In order to solve at least one of the above problems, the clamping device 100 of the present embodiment further includes a positioning assembly 120. The positioning assembly 120 functions to position the part 300 to be machined.
Specifically, when the component 300 to be processed is loaded, the positioning assembly 120 may perform stop positioning on the component 300 to be processed through moving or state change, so as to ensure that the component 300 to be processed can reach an accurate position when being loaded. After the positioning is completed, the positioning assembly 120 is reset again by moving and walking or state change, and the reset positioning assembly 120 avoids the part 300 to be processed. Subsequently, the clamping assembly 110 can clamp and fix the component 300 to be machined under the driving action of the corresponding driving component, so that the cutting tool starts to perform cutting machining on the component 300 to be machined.
In order to realize the moving walking or the state change of the positioning assembly 120, the positioning assembly 120 of the present embodiment includes a driving portion 122 and a positioning portion 124. The driving portion 122 may be a driving device such as an air cylinder, an oil cylinder, or an electric motor, and drives the positioning portion 124 to move back and forth, so that the positioning portion 124 can stop or avoid the to-be-processed member 300. The positioning portion 124 has a plate-shaped structure, and when the positioning portion 124 stops the member to be processed 300, one side surface of the plate-shaped structure abuts against the member to be processed 300 to prevent the movement of the member to be processed 300.
The first direction Y of the present embodiment may be a horizontal direction or a vertical direction, and may be determined according to the structure of the machine tool 200 or the processing manner of the component 300 to be processed.
The clamping device 100 of the embodiment has the advantages of simple structure, convenience in maintenance and high automation degree, improves the positioning precision of clamping through the positioning assembly 120, lightens the labor intensity of workers, improves the production efficiency, and further reduces the production cost on the basis of ensuring the processing quality.
In addition, it should be noted that, compared with the technical solution of secondary clamping in the related art, the clamping device 100 of the present embodiment can complete the processing of the component 300 to be processed only by one-time clamping. Therefore, the clamping device 100 of the present embodiment does not require additional clamping equipment and different jaw devices, and does not have the problems of labor waste, time waste and accuracy non-guarantee caused by secondary clamping. The automatic processing device is high in automation degree, and better in processing efficiency and effect.
