technical field

The utility model relates to pipe material cutting equipment, in particular to a pipe fitting clamping mechanism of a fully automatic pipe cutting machine.

Background technique

At present, conventional pipe cutting machines generally use the following methods to cut pipes:

1. Manual feeding, using a ruler to determine the cutting length of the pipe fittings. Due to manual feeding, the operator visually inspects the length with his eyes. Due to the different viewing angles, the error of determining the length is at least ±0.8mm, which cannot meet the requirements of producing high-precision products.

2. Fix the assembly of the grinding wheel cutting machine, and the operator pushes the hose by hand to cut it off. The straightness of the operator's hand push directly affects the straightness of the incision of the pipe cutting.

Example 3

As shown in Figure 2, on the basis of Embodiment 2, in order to facilitate clamping positioning and automatic alignment of the clamping center, the cylinder 44 is fixed on the workbench 1 through a bracket, and the two semi-circular The clamping part 42 is connected to the piston rod 45 via a connecting rod 43 .

The working principle of the above-mentioned automatic pipe cutting machine is: firstly, the pipe to be cut is sent into two driving brackets arranged in a line, and when the pipe cutting machine is not started, the driving wheel and roller in the driving bracket There is a large feeding gap between the pressure rollers. The pipe cutting machine can be started after the pipe material is sent to the predetermined position, and of course the pipe cutting machine can also be started in advance. After the pipe cutting machine is started, firstly, the rolling wheel is driven by the cylinder at the upper end of the driving bracket, and the pipe is clamped between the driving wheel and the rolling wheel along the slide rail in the driving bracket. Among them, the driving wheel and the rolling wheel are installed on the driving shaft and the rolling shaft respectively, and bearings and bearing brackets are installed at both ends of the driving shaft and the rolling shaft. The bearing bracket of the driving shaft is fixedly installed on the driving bracket. The two sides of the bearing bracket are equipped with sliders, which cooperate with the slide rails set in the driving bracket. The upper end of the bearing bracket of the rolling shaft is connected with the piston rod on the driving cylinder, and the piston rod drives the rolling wheel to slide up and down. . After the rolling wheel clamps the pipe between the driving wheel and the rolling wheel, the driving wheel rotates under the drive of the stepping motor, and at the same time drives the auxiliary driving wheel to rotate synchronously through the belt wheel. The pair of rolling wheels pressed against the pipe also rotate passively, and the pipe is driven forward by friction under the extrusion of the driving wheel and the rolling wheel. Since the electric signal of the angle or the number of turns of the stepper motor can be collected by the sensor, the control circuit can accurately control the electric signal in the control circuit according to the electric signal collected and the data of the radius of the driving wheel input or stored in the control circuit. The length data of the pipe being fed is calculated, and an infrared distance sensor is installed at the other end of the cutting machine. The control circuit can compare the electrical signals collected by the above two sensors with the cutting length data stored or input into the control circuit after internal processing. When the set length value is the same as the measured length of the sensor, the control circuit sends out a control instruction. First, the clamping cylinder installed on one side of the drive bracket drives the clamp to clamp the pipe, and at the same time the stepping motor stops rotating. Then it is activated by the cutting drive cylinder arranged between the drive bracket and the clamping cylinder, wherein the cutting drive cylinder is fixed on the worktable, the piston in the cylinder is connected with the lower end of the slide table, and the slide table is driven along the direction perpendicular to the pipe feeding direction. At this time, the cutting drive motor installed on the slide table is also started. The cutting drive motor drives the cutting drive shaft to rotate through the pulley and the belt. A cutting tool is installed at the other end of the cutting drive shaft. The pipe can be cut off under the drive of the sliding table. Then the clamping cylinder resets, the clamp releases the clamped pipe, and the cut pipe is installed on one side of the workbench and on the side bracket above the workbench. The baffle plate can send the cut pipe into the discharge chute arranged on the workbench. At the same time, the cutting drive cylinder resets, the sliding table drives the cutting tool back to the initial state, and then the stepping motor starts again to enter the next feeding and cutting cycle program.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
