Technical Field
[0001] The present application relates to the technical field of grinding, and in particular to a device for grinding the end of a metal pipe. Background Art
[0002] A grinder is a mechanical device used to grind, polish or trim the surface of an object. It is usually driven by an electric motor and equipped with grinding tools such as grinding wheels, grinding belts, and polishing wheels of different types and specifications to adapt to different materials and processing requirements.
[0003] After metal pipes are cut, the inner and outer rings of the cut end faces usually have burrs, which need to be polished before use.
[0004] The commonly used hand-held grinders have a large grinding wheel diameter, so they can only grind and remove burrs on the outer ring of the end of a small-diameter metal pipe, but are difficult to remove burrs on the inner ring. Therefore, they have poor applicability and obvious shortcomings. Utility Model Content

[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The embodiment of the present application discloses a metal pipe end grinding device.
[0033] Reference Figure 1 The metal pipe end grinding device includes a frame 1, a motor 2 bolted to the frame 1 and electrically connected to a control system, a disc 3 is coaxially connected to the output shaft of the motor 2, and flexible bristles 4 are densely distributed on the side of the disc 3 axially facing away from the motor 2. The disc 3 is made of synthetic rubber, and the flexible bristles 4 are grinding wires in the prior art.
[0034] Reference Figure 1 and Figure 2 A clamping seat 5 is placed on the frame 1, and a plurality of placement grooves 51 for placing the pipes to be processed are opened on the clamping seat 5. The plurality of placement grooves 51 are parallel to the axis of the output shaft of the motor 2, and the plurality of placement grooves 51 are arranged in a direction perpendicular to the axis of the output shaft of the motor 2.
[0035] Reference Figure 1 and Figure 2 The clamping seat 5 is provided with a clamping member for clamping the pipe to be processed, and the frame 1 is also provided with a driving member for driving the clamping seat 5 to move back and forth linearly.
[0036] Reference Figure 1 and Figure 2 The driving member includes a base 71 slidably arranged on the frame 1 and a movable cylinder 72 bolted to the frame 1. The base 71 is slidably matched with the base 71 through a slider and a slide rail, and the clamping seat 5 is bolted to the base 71. The piston rod of the movable cylinder 72 is perpendicular to the output shaft of the motor 2, and the piston rod of the movable cylinder 72 is threadedly connected to the base 71 and electrically connected to the control system.
[0037] Reference Figure 1 and Figure 2 The clamping member includes a fixed seat 12 bolted to the base 71 and covered outside the clamping seat 5, a pressing cylinder 61 bolted to the fixed seat 12 and electrically connected to the control system, the piston rod of the pressing cylinder 61 slides through the fixed seat 12 and is threadedly connected to an arm plate 63, and a plurality of pressing blocks 62 are bolted to the arm plate 63, and one pressing block 62 corresponds to one placement groove 51 and slides with it.
[0038] Reference Figure 1 and Figure 2 The worker manually puts a pipe to be processed into each placement slot 51, and then starts the pressing cylinder 61 through the control system. The piston rod of the pressing cylinder 61 extends downward, and the arm plate 63 simultaneously drives all the pressing blocks 62 to move downward, so that the pressing blocks 62 are pressed tightly on the corresponding pipe to be processed.
[0039] Considering that the plurality of pressing blocks 62 are all driven to move by one arm plate 63 , a clearance groove 54 is vertically provided on the clamping seat 5 at a position relative to the vertical movement of the arm plate 63 .
[0040] Reference Figure 1 and Figure 2 , the control system starts the motor 2, and the output shaft of the motor 2 drives the flexible bristles 4 to rotate through the turntable. At this time, the piston rod of the movable cylinder 72 retracts, and then drives the pipe to be processed to move through the base 71 and the clamping seat 5.
[0041] During this process, the pipe to be processed will move until it contacts the flexible bristles 4, and the flexible bristles 4 will bend and deform accordingly and move into the inside of the pipe. In this way, the flexible bristles 4 can simultaneously deburr the inner and outer rings of the end of the pipe, thereby improving the deburring effect of the grinding device.
[0042] Reference Figure 1 and Figure 2 The bottom of the placement groove 51 is V-shaped, and the bottom of the pressing block 62 is an inverted cone-shaped. When pipes of different diameters to be processed are placed in the placement groove 51, the bottom of the pressing block 62 and the bottom of the placement groove 51 can cooperate to achieve stable clamping of the pipes.
[0043] Reference Figure 2 and Figure 3 When grinding the end of the pipe fitting, it is necessary to consider the distance between the end of the pipe fitting and the disc 3. Too large or too small a distance may lead to poor grinding effect. In the present application, the pipe fitting to be processed is placed in the placement groove 51 manually, so it is difficult to control the distance between the end of the pipe fitting and the disc 3.
[0044] Reference Figure 2 and Figure 3 To this end, a stop block 8 is placed on the side of the clamping seat 5 opposite to the placement groove 51 where the pipe to be processed is placed. The two opposite sides of the clamping seat 5 are provided with sliding grooves 52 parallel to the placement groove 51. The stop block 8 is bolted with a sliding rod 9 that extends into the sliding groove 52 and slides with it. A magnetic block 10 for magnetically attracting the pipe to be processed is embedded in the position of the stop block 8 relative to each placement groove 51.
[0045] Reference Figure 2 and Figure 3 When the worker places the pipe to be processed in the placement groove 51, he manually moves the stop block 8 to a suitable position, and the magnetic block 10 sucks the pipe to be processed tightly against it. Then the pressing block 62 presses the pipe to be processed downward to control the distance between the end of the pipe to be processed and the turntable, thereby reducing the possibility of poor deburring effect caused by the distance between the end of the pipe to be processed and the turntable being too close or too far.
[0046] Reference Figure 2 and Figure 3 When deburring pipes of different lengths, the position of the stop block 8 also needs to be adjusted accordingly. For this purpose, a plurality of adjustment holes 53 are opened in the slide groove 52 along its length direction. The adjustment holes 53 are plugged into and matched with the limit pin 11. The limit pin 11 is located between the end of the slide groove 52 away from the stop block 8 and the slide rod 9.
[0047] The implementation principle of a metal pipe end grinding device in an embodiment of the present application is as follows: the control system starts the motor 2, and the output shaft of the motor 2 drives the flexible bristles 4 to rotate through the turntable. The worker manually puts a pipe to be processed into each placement slot 51, and then manually moves the stop block 8 to a suitable position. The magnetic block 10 sucks the pipe to be processed until it is close to it, and the piston rod of the pressing cylinder 61 extends downward, so that the arm drives the pressing block 62 to press the pipe to be processed downward. Subsequently, the piston rod of the movable cylinder 72 retracts and then extends, and then drives the pipe to be processed to move through the base 71 and the clamping seat 5. In this process, the pipe to be processed will move to contact with the flexible bristles 4, and the flexible bristles 4 will bend and deform accordingly and move to the inside of the pipe, so that the flexible bristles 4 can simultaneously deburr the inner and outer rings of the end of the pipe, thereby improving the deburring effect of the grinding device.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
