Description

Technical Field

[0001] The utility model relates to the technical field of shield tool processing, in particular to a positioning device for shield tool processing. Background Art

[0002] The excavation system in the shield machine is the excavation cutterhead and its drive system. The shield machine excavation cutterhead is a rotating or shaking disc-shaped excavator, which is composed of a cutter for excavating the strata, a panel for stabilizing the excavation surface, an excavation notch, a rotating or shaking drive mechanism, a bearing mechanism, etc. During the shield cutter processing process, a positioning device is required to fix the shield cutter through the positioning device so that the subsequent processing equipment can process the shield cutter.

[0003] Such devices currently on the market are clamped and fixed on both sides during use, but due to the limited clamping area on both sides, the clamping firmness is poor, and displacement is likely to occur during the processing, thus affecting the processing effect.

[0004] Therefore, in view of the above technical problems, it is necessary to propose a positioning device for shield tool processing. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning device for shield tool processing, so as to solve the problem that the device proposed in the above background technology is clamped and fixed on both sides during use, but due to the limited clamping area on both sides, the clamping firmness is poor, and then displacement occurs easily during the processing, thereby affecting the processing effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning device for shield tool processing, comprising: a supporting assembly, a clamping assembly and a fixing assembly, wherein the supporting assembly is installed on the workbench of the processing equipment by bolts and nuts; the clamping assembly is arranged on the supporting assembly, and the clamping assembly comprises a turntable, a connecting horizontal plate rotating above the turntable, a connecting seat rotating on the connecting horizontal plate and a clamping vertical plate rotating on the top of the connecting seat, and the clamping vertical plate passes through the supporting assembly, and the clamping assembly is used to clamp the shield tool object; the fixing assembly is arranged on the clamping assembly, and the fixing assembly is used to position and fix the shield tool object.

[0007] Preferably, the support assembly includes a bracket mounted on a workbench of the processing equipment by means of bolts and nuts, an object placement table disposed on the bracket, and a connecting column fixed between the object placement table and the bracket.

[0008] By adopting the above technical solution, the bracket and the processing equipment are connected, and the object placement table is used to place the shield tool to be processed.

[0009] Preferably, the support assembly further comprises four strip-shaped slide grooves provided on the object placement table, and the four strip-shaped slide grooves are distributed in a ring shape with respect to the center line of the object placement table.

[0010] By adopting the above technical solution, the four strip slide grooves guide the connecting seat, thereby enabling the connecting seat to smoothly move the shield cutter left and right or front and back.

[0011] Preferably, the clamping assembly includes a connecting rotating column that rotates between the bracket and the object placement table, and a first servo motor that is installed in the bracket and drives the connecting rotating column to rotate.

[0012] By adopting the above technical solution, the first servo motor is started, and the connecting column is driven to rotate through the output shaft of the first servo motor. During the rotation process, the connecting column drives the lower installation of the turntable, thereby making the connecting cross plate present an inclined or horizontal state.

[0013] Preferably, there are four connecting seats in total, and the four connecting seats are all penetrated through the object placement table through a strip slide groove.

[0014] By adopting the above technical solution, four connecting seats can be used to clamp the shield cutter on four sides, thereby improving the firmness of the shield cutter clamping.

[0015] Preferably, the clamping assembly further comprises a second servo motor mounted on the outer wall of the connecting seat, and the output shaft of the second servo motor and the clamping vertical plate are fixedly connected to one end of the connecting seat connecting short shaft.

[0016] By adopting the above technical solution, the output shaft of the second servo motor is rotated to drive the connecting seat to rotate. When there is no need to use so many connecting seats, the connecting seat can be hidden under the object placement table, so that the shield cutter can be extruded and fixed by relative forces on both sides using two relative connecting seats.

[0017] Preferably, the fixing assembly includes a U-shaped frame fixed to one end away from the connecting seat, a guide vertical plate sliding in the U-shaped frame, a buffer spring fixed to the guide vertical plate and the inner wall of the U-shaped frame, and a clamping positioning column fixed to one end of the guide vertical plate away from the buffer spring, and the clamping positioning column passes through the connecting seat.

[0018] By adopting the above technical solution, when the connecting seat is close to the shield cutter, the clamping positioning column contacts the shield cutter. The clamping positioning column can be inserted into the shield cutter or contact and squeeze the shield cutter, thereby improving the firmness of the shield cutter clamping and positioning.

[0019] Compared with the prior art, the beneficial effects of the utility model are: first, the connecting column is driven to rotate by the output shaft of the first servo motor, and the turntable rotates when the connecting column rotates, and then the four clamping vertical plates are close to each other at the same time, and the four clamping vertical plates can be used to clamp the shield tool to be processed on all sides, thereby improving the stability of the shield tool during processing; second, by providing a connecting seat and a second servo motor, the clamping vertical plates are driven to rotate by the output shaft of the second servo motor, and the clamping vertical plates can be rotated to hide the clamping vertical plates under the object placement table, so that the object can be clamped and fixed by the two clamping vertical plates relative to each other, thereby realizing two clamping methods for positioning the shield tool.

During the rotation of the connecting column 27, the turntable 22 is driven to rotate. While the turntable 22 rotates, the clamping vertical plate 24 moves smoothly with the cooperation of the strip slide 14. At this time, the angle between the connecting cross plate 23 and the strip slide 14 gradually increases. At this time, the clamping vertical plate 24 clamps and fixes the shield tool to be processed; start the second servo motor 26, and the output shaft of the second servo motor 26 drives the connecting seat 25 to rotate, and the connecting seat 25 is hidden under the object placement table 13.
