[0047] Considering that for drilling holes on the arc surface of round sleeve products, the original process flow is to manually mark the positions of each hole, then use a milling machine to mill a small plane on each arc surface (for drill bit positioning), and then use a drilling machine or boring machine to drill holes. When drilling, a pressure plate is used to press, and after completing the arc hole on one side, the angle is rotated, and then the next drilling process is performed after re-pressing. In this way, the drilling process is long and the efficiency is low, the drill bit positioning is inaccurate and the quality cannot be guaranteed.

[0048] like Figure 1 and Figure 2 As shown, in view of this, an embodiment of the present application provides a drilling clamping device for round sleeve-type parts, including: a workbench 110; a fixed part 120, the fixed part 120 is connected to the workbench 110; a first clamp 130, the first clamp 130 is connected to the fixed part 120; a movable part 140, the movable part 140 is used to approach or move away from the fixed part 120; a second clamp 150, the second clamp 150 is connected to the movable part 140; a drilling sleeve 160, the drilling sleeve 160 includes a plurality of processing planes 161, each processing plane 161 is formed with a plurality of positioning holes 162, the drilling sleeve 160 is used to be arranged between the first clamp 130 and the second clamp 150, and is sleeved on the round sleeve-type part 170 to be processed.

[0049] The drilling clamping device for round sleeve parts provided in the embodiment of the present application includes a workbench 110, a fixed part 120, a first clamp 130, a movable part 140, a second clamp 150 and a drilling sleeve 160. Based on this, during use, the round sleeve part 170 to be processed is sleeved on the first clamp 130, and the round sleeve part 170 to be processed can be supported by the first clamp 130, and then the round sleeve part 170 to be processed is locked by the first clamp 130. 0, then the drilling sleeve 160 is sleeved on the circular sleeve part 170 to be processed, the movable part 140 is moved, and the second clamp 150 is extended into the circular sleeve part 170 to be processed, to support and clamp the circular sleeve part 170 to be processed, and then the movable part 140 is fixed to complete the clamping of the circular sleeve part 170 to be processed, and then the processing plane 161 and the positioning hole 162 on the drilling sleeve 160 can be used to drill the circular sleeve part 170 to be processed. In the present application, the first clamp 130 and the second clamp 150 are extended into the circular sleeve part 170 to be processed to support the circular sleeve part 170 to be processed, which can reduce the probability of deformation of the circular sleeve part 170 to be processed. The drilling sleeve 160 is sleeved on the circular sleeve part 170 to be processed, and the circular sleeve part 170 to be processed is drilled by using the processing plane 161 and the positioning hole 162, thereby ensuring the positioning accuracy and processing efficiency. The multi-angle arc drilling process can be completed through one clamping, which effectively ensures the product accuracy, improves the product quality, and accelerates the product manufacturing efficiency.

[0050] It can be understood that the drilling clamping device for circular sleeve parts includes multiple processing planes 161 through the drilling sleeve 160. The drilling tool can use the processing planes 161 to process the circular sleeve parts 170 to be processed, which effectively avoids the deviation of the tool when drilling the arc surface, solves the technical difficulties of serious tool waste and inaccurate hole positioning, and has accurate clamping, continuous and reliable manufacturing links, and improves the processing efficiency by more than 40%.

[0051] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the drilling and clamping device for round sleeve parts also includes: a driving member 180, the driving member 180 is arranged on the fixing part 120, the driving member 180 is connected to the first clamp 130, and is used to drive the first clamp 130 to rotate; wherein, when the first clamp 130 rotates, the second clamp 150 moves with the first clamp 130.

[0052] In this technical solution, the drilling clamping device for round sleeve parts can also include a driving member 180, which is connected to the first clamp 130. After the round sleeve part 170 to be processed is clamped, the driving member 180 can drive the round sleeve part 170 to be processed to rotate through the first clamp 130 by opening the driving member 180, and the second clamp 150 moves accordingly, so that the round sleeve part 170 to be processed can be exposed to the drill bit at different angles. Through one clamping, different areas of the round sleeve part 170 to be processed can be drilled, which greatly improves the processing efficiency.

[0053] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the drilling clamping device for round sleeve parts also includes: a locking member 190, which is arranged on the drilling sleeve 160, and the locking member 190 is used to pass through the drilling sleeve 160 and abut against the round sleeve part 170 to be processed.

[0054] In this technical solution, the drilling clamping device for round sleeve parts also includes a locking piece 190. After the drilling sleeve 160 is sleeved on the round sleeve part 170 to be processed, the drilling sleeve 160 can be locked by abutting against the round sleeve part 170 to be processed, thereby avoiding displacement of the drilling sleeve 160 during processing and further ensuring processing accuracy.

[0055] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the drilling and clamping device for round sleeve parts also includes: a fixing hole 200, a plurality of fixing holes 200 are arranged at intervals along the length direction of the workbench 110, and the movable part 140 includes a positioning column 141, and the positioning column 141 is used to be inserted into the fixing hole 200.

[0056] In this technical solution, the drilling and clamping device for round sleeve parts also includes a fixing hole 200, and the movable part 140 includes a positioning column 141. When the positioning column 141 is separated from the fixing hole 200, the movable part 140 can be in a free moving state. Based on this, after the round sleeve part 170 to be processed is clamped on the first clamp 130, the position of the movable part 140 can be adjusted. After the movable part 140 is adjusted to a suitable position, the positioning column 141 can be inserted into the fixing hole 200, and then the second clamp 150 is used to clamp the round sleeve part 170 to be processed, so that the clamping of the round sleeve part 170 to be processed can be completed.

[0057] It is understandable that there may be a plurality of positioning posts 141 , for example, the positioning posts 141 may be distributed on both sides of the movable portion 140 , so as to make the positioning of the movable portion 140 more reliable.

[0058] In a feasible embodiment, the drilling and clamping device for round sleeve parts also includes: a fixing member, a slideway is formed on the workbench 110, the movable part 140 is slidably connected to the slideway, and the fixing member is used to lock the movable part 140 on the workbench 110.

[0059] In this technical solution, another movable mode of the movable part 140 is further provided, and a slideway can be directly set on the workbench 110, and the slideway drives the movable part 140 to adjust the position of the second clamp 150, and then the movable part 140 is locked by the fixed part 120. The fixed part 120 can be a pin or a screw.

[0060] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the first clamp 130 and the second clamp 150 both include: a clamp body 131; a clamping jaw 132, which is telescopically connected to the clamp body 131; an adjusting component 133, which is disposed in the clamp body 131 and is connected to the clamping jaw 132, for driving the clamping jaw 132 to extend or retract into the clamp body 131.

[0061] In this technical solution, the structural composition of the first clamp 130 and the second clamp 150 is further provided. The structures of the first clamp 130 and the second clamp 150 can be the same. The clamp body 131 can be columnar. In this way, the clamp body 131 is inserted into the circular sleeve part 170 to be processed to support the circular sleeve part 170 to be processed, and then the clamping jaws 132 are extended to clamp the circular sleeve part 170 to be processed. The adjustment component 133 is used to adjust the clamping jaws 132 to extend or retract the clamp body 131. On the one hand, it is convenient to lock and unlock the circular sleeve part 170 to be processed; on the other hand, by adjusting the position of the clamping jaws 132, the clamping jaws 132 can clamp the circular sleeve part 170 to be processed with different inner diameters, thereby increasing the scope of application.

[0062] In a feasible embodiment, the adjustment assembly 133 includes: an adjusting screw, which is arranged on the clamp body 131; a lead screw, to which the adjusting screw is connected and used to drive the lead screw to rotate, and the lead screw is connected to the clamping jaw 132 and used to drive the clamping jaw 132 to extend or retract the clamping body 131; and a reset member, which abuts against the clamping jaw 132.

[0063] In this technical solution, the structural composition of the adjustment component 133 is further provided. The adjustment component 133 may include an adjusting screw, a lead screw and a reset member. The position of the clamp 132 can be adjusted by adjusting the position of the lead screw through the adjusting screw, and the reset member applies stress to the clamp 132, so that the clamp 132 can clamp the circular sleeve-type part 170 to be processed.

[0064] In a feasible implementation, the drilling and clamping device for round sleeve parts further includes: a calibration block, which is disposed on the workbench 110 , and has a plurality of calibration surfaces formed on the calibration block, each calibration surface having a different inclination angle with the workbench 110 .

[0065] In this technical solution, it is taken into consideration that, under some working conditions, the orientation of the holes to be processed in the circular sleeve-type part 170 may not all be perpendicular to the surface of the circular sleeve-type part 170 to be processed, and holes with a moving slope may also need to be processed. Therefore, a calibration block can be set on the workbench 110, and the calibration block can include multiple calibration surfaces. Based on this, when using a machine tool for processing, calibration surfaces of different angles can be identified by an image recognition device, and then holes of different angles can be processed, which can further improve the processing accuracy.

[0066] In a feasible implementation, the drilling sleeve 160 includes: a cylinder body, on which a plurality of processing planes 161 are formed, and the cross-section of the cylinder body is a polygon formed by splicing the plurality of processing planes 161; and a filling piece, which is arranged on the inner wall of the cylinder body.

[0067] In this technical solution, a structural composition of a drilling sleeve 160 is further provided. The drilling sleeve 160 may include a cylinder and a filling piece. Through the setting of the cylinder, a plurality of processing planes 161 are formed on the cylinder to ensure processing accuracy. Through the setting of the filling piece, the probability of the cylinder rotating relative to the circular sleeve-type part 170 to be processed can be reduced, which can further ensure processing accuracy.

[0068] In a feasible implementation, the filling piece is made of rubber material. Such an arrangement enables the filling piece to have a certain elasticity, and can avoid deformation of the circular sleeve-like part 170 to be processed due to the arrangement of the drilling sleeve 160 .
