[0021] Example

[0022] The prior art pipe expanding auxiliary tooling for pipe processing generally requires manual operation of the auxiliary tooling during use, and the pipe is clamped and fixed on the operating table 1, and then the expanding device is used to expand the pipe at one end, but synchronous expansion of both ends of the pipe cannot be achieved, resulting in low expansion efficiency.

[0023] To do this, see Figure 1-3 The utility model provides a pipe expansion operation auxiliary tool for pipe processing, comprising: an operating table 1, a bracket 42 is fixedly connected to the middle of the top of the operating table 1, a V-shaped notch 43 is opened at the top of the bracket 42, and the V-shaped notch 43 is used to place the pipe, and motors b3 are respectively provided on both sides of the bracket 42, and the output shafts of the two motors b3 are fixedly connected to the expansion head 31, and a synchronous drive component 2 is connected between the two motors b3 and the operating table 1, and the synchronous drive component 2 is used to realize the relative movement of the two expansion heads 31;

[0024] A synchronous clamping and fixing assembly 4 is connected between the two motors b3 and the bracket 42. The synchronous clamping and fixing assembly 4 is used to clamp the pipe when the two expansion heads 31 move relative to each other.

[0025] Further Figure 1-3As shown, it is worth explaining in detail that in order to enable the two expansion heads 31 to move synchronously relative to each other and realize synchronous expansion of the two ends of the pipe fitting, a synchronous drive assembly 2 is provided, including a sliding seat 21 fixed to the bottom ends of the two motors b3, the vertical cross-section of the sliding seat 21 is a convex structure, and the sliding seat 21 is slidably connected to the sliding groove provided at the top of the operating table 1, and the two sliding seats 21 are threadedly connected with the same bidirectional screw 22, and both ends of the bidirectional screw 22 are rotatably connected to the sliding groove, one end of the bidirectional screw 22 extends to the outside of the operating table 1, and is connected to the output shaft of the motor a23, and the motor a23 is fixed to the outside of the operating table 1.

[0026] Among them, the motor a23 is a forward and reverse motor, which can realize the forward and reverse rotation of the bidirectional screw 22.

[0027] Further Figure 1-3 As shown, it is worth specifically explaining that in order to be able to clamp the pipe fittings without manual intervention when the two expansion heads 31 move synchronously relative to each other, a synchronous clamping and fixing assembly 4 is provided, including two symmetrically arranged clamping plates 44 arranged above the V-shaped notch 43, and the two clamping plates 44 are provided with V-shaped clamping openings 441 on the opposite sides, and the side walls of the two clamping plates 44 that are separated from each other are fixedly connected with C-shaped rods 45, and the outer sides of the C-shaped rods 45 are movably sleeved with two symmetrically arranged limit blocks 46, and the limit blocks The bottom ends of 46 are fixed to the top of the bracket 42, and the ends of the limit blocks 46 facing away from the V-shaped notch 43 are connected to the C-shaped rod 45 through springs 47, and the springs 47 are movably sleeved on the outside of the C-shaped rod 45.

[0028] When the L-shaped pressure rod 41 moves toward the pressure block 48, the inclined surface b at one end of the L-shaped pressure rod 41 will squeeze the inclined surface a481 of the pressure block 48, so that the two C-shaped rods 45 move relative to each other, and the two clamping plates 44 clamp the pipe fittings and fix them on the bracket 42. In addition, the springs 47 are compressed.

[0029] In summary: when using the pipe expanding operation auxiliary tooling for pipe processing, the pipe to be expanded can be placed on the bracket 42, and then, by starting the motor b3, the bidirectional screw 22 is driven to rotate, so that the expanding heads 31 driven by the two motors b3 can move relative to each other. In addition, when the two L-shaped pressure rods 41 move toward the corresponding side of the pressed block 48, the inclined surface b at one end of the L-shaped pressure rod 41 will squeeze the inclined surface a481 of the pressed block 48, so that the two C-shaped rods 45 move relative to each other, and the two clamping plates 44 clamp the pipe and fix it on the bracket 42. After clamping, the two expanding heads 31 can continue to move relative to each other, and can complete the synchronous expanding of the two ends of the pipe at one time, thereby greatly improving the efficiency of expanding.

[0030] Motor a23 and motor b3 can be purchased on the market. Motor a23 and motor b3 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
