Description

Technical Field

[0001] The utility model relates to the field of pipe fitting processing, in particular to an auxiliary tooling for pipe fitting processing. Background Art

[0002] Round pipe fittings are the most commonly used type of pipe fittings. Round pipe fittings are often cut and drilled during the processing process, and the pipe fittings need to be fixed.

[0003] Currently, a Chinese utility model patent with publication number CN205869529U discloses a circular tube drilling fixture, which includes a fixing frame for fixing the circular tube, with a fixing frame fixed at each end of the circular tube; a drilling machine fixing platform that can move back and forth along the circular tube is provided between the two fixing frames on the circular tube.

[0004] An existing patent discloses a circular tube drilling and fixing tool, which can realize drilling processing after fixing a circular tube. However, it can be seen from its description and drawings that the tube is fixed by a second arc tube installed on the base, and the base and the second arc tube do not have adjustment capabilities. Therefore, the tube can only be fixed on a specific axis, which reduces the flexibility of processing. Utility Model Content

[0005] The purpose of the utility model is to provide an auxiliary tool for pipe fitting processing, which has the advantages of being able to flexibly adjust the pipe fitting and improve processing flexibility.

[0006] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions: an auxiliary tool for pipe processing, comprising a support body and:

[0007] A sliding frame slidably mounted on the support body, wherein a rotating frame is hingedly connected to the sliding frame;

[0008] A clamping wheel assembly provided on the rotating frame, for fixing the axis of the pipe and driving the pipe to rotate around its axis; and

[0009] The locking assembly is used to lock the pipe so that it cannot rotate around the axis.

[0010] Through the above technical solution, the pipe fitting is clamped by the clamping wheel group during use, and the pipe fitting can be driven to rotate freely around its axis, which is suitable for use when performing circumferential processing around the pipe fitting; at the same time, the rotating frame can rotate, driving the clamping wheel group to deflect and thereby change the axial direction of the pipe fitting, thereby enabling flexible adjustment of the pipe fitting; when the pipe fitting does not need to rotate, the locking assembly locks the pipe fitting and fixes it, enhancing the stability of the pipe fitting and thereby improving the processing accuracy; at the same time, the movement of the sliding frame can drive the movement of the pipe fitting. This solution can flexibly adjust the pipe fitting, thereby improving the flexibility of processing.

[0011] In one embodiment of the present invention, the rotating frame includes a mounting plate, which is arranged perpendicular to the sliding direction of the even-numbered sliding frame, and the clamping wheel group includes: at least two abutment wheels hinged to the mounting plate, the axial direction of the abutment wheel is arranged perpendicular to the mounting plate, and the abutment wheel is connected to a driving source to drive the pipe to rotate; and a pressure wheel, the pipe is arranged between the abutment wheel and the pressure wheel, and a pressure driving member is provided on the mounting plate, and the pressure driving member drives the pressure wheel to move, so that the pressure wheel applies a force to the pipe directed to the abutment wheel to clamp the pipe so that its axis is fixed.

[0012] Through the above technical solution, the clamping drive drives the clamping wheel to move, so that the clamping wheel and the abutment wheel cooperate to clamp the pipe fitting. The abutment wheel is driven to rotate by the driving source and uses friction to drive the pipe fitting to rotate, so that the pipe fitting can be flexibly processed circumferentially.

[0013] In one embodiment of the present invention, a rotating seat is hinged on the mounting plate, the pressure wheel is installed on the rotating seat, and the pressure driving component is configured as a pressure cylinder, which drives the rotating seat to rotate so that the pressure wheel presses the pipe fitting.

[0014] Through the above technical solution, the pressing cylinder drives the rotating seat to rotate so that the pressing wheel presses the pipe fitting.

[0015] In one embodiment of the present invention, the sliding frame includes a first sliding plate slidably assembled on the support body, and a first sliding rail is fixed on the first sliding plate, and the length direction is perpendicular to the sliding direction of the first sliding plate; and a second sliding plate slidably assembled on the first sliding rail. The sliding frame, the rotating frame and the clamping wheel group are arranged in two groups along the sliding direction of the first sliding plate to perform multi-point clamping of the pipe to enhance stability.

[0016] With the above technical solution, the pipe is clamped and fixed by two sets of clamping wheels, which can enhance the stability of the fixation. When the rotating frame rotates to drive the pipe to deflect, the second sliding plate slides to provide a margin for the pipe to deflect.

[0017] In one embodiment of the present invention, the locking assembly includes: a fixed arc plate fixed to the mounting plate; a movable arc plate hinged to the fixed arc plate, through which the pipe passes between the fixed arc plate and the movable arc plate; and a locking cylinder that applies a force directed toward the fixed arc plate to the movable arc plate so that the fixed arc plate and the movable arc plate clamp the pipe.

[0018] Through the above technical solution, when the pipe fitting needs to be fixed circumferentially, the locking cylinder applies a pressing force to the movable arc plate, thereby pressing and fixing the pipe fitting.

[0019] As described above, the auxiliary tooling for pipe processing of the present invention has the following beneficial effects:

[0020] During use, the pipe fitting is clamped by the clamping wheel group, and the pipe fitting can be driven to rotate freely around its axis, which is suitable for use in circumferential processing around the pipe fitting; at the same time, the rotating frame can rotate, driving the clamping wheel group to deflect and thereby change the axial direction of the pipe fitting, thereby enabling flexible adjustment of the pipe fitting; when the pipe fitting does not need to rotate, the locking assembly locks the pipe fitting and fixes it, enhancing the stability of the pipe fitting and thus improving the processing accuracy. At the same time, the movement of the sliding frame can drive the movement of the pipe fitting. This solution can flexibly adjust the pipe fitting, thereby improving the flexibility of processing.
