[0019] See also Figure 1-4 In this embodiment, a deburring device for metal pipe fittings includes an operating table 1, a stand 2 is fixed on the table top of the operating table 1, and two push cylinders 5 are relatively distributed below the stand 2, and a rotating component 9 is installed on the operating table 1 between the two push cylinders 5, the ejection end of the push cylinder 5 is fixed with a push plate 6 that slides on the operating table 1, and two push plates 6 are fixed with two L-shaped clamps 12, two adjacent L-shaped clamps 12 are opposite, and the two relatively distributed L-shaped clamps 12 are installed on the opposite sides. A grinding device 14 is installed on the top of the stand 2, and a screw device 3 is installed on the moving end of the screw device 3. A clamping component 4 that slides on the stand 2 is fixed.

[0020] In the above structure, the screw device can drive the clamping assembly to move left and right to adjust the position of the clamping end. At the same time, the clamping assembly can clamp and fix the pipe fittings, and the function of transplanting the pipe fittings is realized under the screw device. During the transplanting process, the push cylinder drives the push plate to move oppositely, so that the clamping and fixing can be completed through the L-shaped clamp. At the same time, the rotation adjustment of the pipe fitting can be completed through the rotating assembly, so that the unpolished hole on the other side is rotated to be opposite to the L-shaped clamp and also to the grinding end of the grinding device. Then, the grinding end of the cooperating grinding device extends into the hole to complete the grinding operation, and then the unloading is completed by transplanting, thereby realizing automatic loading and unloading and deburring operations, thereby reducing the labor workload of the staff and effectively improving the work and production efficiency.

[0021] like Figure 2-3 The clamping assembly 4 includes a bottom plate 401 which is slidably connected to the stand 2 and fixedly connected to the moving end of the screw device 3, a push cylinder 404 is installed on the back of the bottom plate 401, and seven gears 402 arranged and distributed at equal distances and an elastic component matching the number of the gears 402 are installed inside the bottom plate 401, and a lower rack 403 which slides inside the bottom plate 401 and is connected to one end of the elastic component, the lower rack 403 is meshed with the gear 402, and a cover plate 410 is fixed on the top of the bottom plate 401, the cover plate 410 covers the bottom plate 401, and the push cylinder 404 A long plate 405 is fixed to the ejection end, which is equal to the length of the bottom plate 401 and distributed opposite to the back side thereof. An upper rack 406 matching the number of gears 402 is fixed to the side of the long plate 405 opposite to the bottom plate 401, and the upper rack 406 slides between the bottom plate 401 and the cover plate 410, and meshes with the gear 402. A clamping plate 409 is fixed to one end of the upper rack 406 and the lower rack 403. The length of the lower rack 403 is less than that of the upper rack 406. The two clamping plates 409 at the head end and the tail end are both F-shaped, and the protruding ends are in the same direction, while the clamping plate 409 in the middle is vertically downward. The bottom plate is driven to move left and right on the vertical frame by the screw rod device, so that the clamping plates at the head and tail can be moved to the periphery of the pipe body in an open and closed state, and the push cylinder is operated to push the long plate to drive the upper rack to move. While moving, the upper rack will drive the lower rack to move by meshing with the gear, so that the upper rack and the lower rack drive the clamping plates to move in relative or opposite directions to complete the opening and closing and clamping actions. During the movement of the lower rack, the elastic component will be squeezed to play a buffering role, and it can also play a role in promoting clamping. Then, under the operation of the push cylinder and the operation of the screw rod device, the transplanting operation of the pipe fittings can be completed.

[0022] The elastic component includes a telescopic column 407 fixed to the left side of the lower rack 403, the left end of the telescopic column 407 extends to the outside through the bottom plate 401, and the outer side of the telescopic column 407 is sleeved with a spring 408 inside the bottom plate 401. When the upper rack drives the lower rack to move through the gear, when the two clamps are opened and closed, the lower rack will drive the telescopic column to push outward, and at the same time, the spring will be squeezed through the left end of the lower rack, thereby playing a buffering role. When the clamp is clamped, the lower rack will be pushed to the right under the elastic force of the spring to improve the firmness of the clamping.

[0023] like Figure 4In the direction shown, the rotating assembly 9 includes a bearing seat 906 fixed on the operating table 1 and located between the two grinding devices 14, and a concave plate 901 located below the bearing seat 906 is fixed to the bottom of the operating table 1, two guide rods 902 are fixed on the inner side of the concave plate 901, a forward push cylinder 905 is fixedly installed on the left side of the concave plate 901, a guide block 903 slides between the outer sides of the two guide rods 902, a fixed rack 904 fixedly connected to the ejection end of the forward push cylinder 905 is fixed on the top of the guide block 903, a rotating shaft 908 is fixed to the inner side of the bearing seat 906, a clamping cylinder 909 is installed on the upper end of the rotating shaft 908, and a rotating gear 907 meshing with the fixed rack 904 is fixed on the lower end. When the screw device and the clamping assembly cooperate to deburr the pipe for the first time, the pipe will be moved to the clamping cylinder in the open and closed state, and then the pipe will be clamped and fixed by the clamping cylinder. The clamping assembly is loosened and cooperated with the screw device to move the material left and right, and then the forward push cylinder runs to push the fixed rack to drive the shaft to rotate, so that the pipe can be driven to rotate through the clamping cylinder, so that the hole on the other side is rotated to the grinding position, thereby realizing automatic rotation and adjustment of the position.

[0024] like Figure 1 The top of the front push plate 6 is fixed with an active plate 11, a clamping plate 7 and a shifting block. The active plate 11 is close to the left grinding device 14, the clamping plate 7 is close to the shifting block, and the shifting block is close to the right grinding device 14. The top of the back push plate 6 is fixed with an auxiliary plate 10 opposite to the active plate 11, and is also fixed with an auxiliary clamping block 8 opposite to the clamping plate 7, and an auxiliary shifting block opposite to the shifting block. Through the operation of the push cylinder, the two push plates are driven to move in opposite or opposite directions, so that the active plate and the auxiliary plate can be clamped, and at the same time, the clamping plate and the auxiliary clamping block are clamped, and the shifting block and the auxiliary shifting block are clamped, so that the pipe fitting can be clamped and fixed at the current position to achieve the role of pre-waiting.

[0025] The top of the cover plate 410 is provided with a push-down cylinder 15 located above the clamping plate 409 at the tail end, and a rotary motor 16 is provided at the ejection end of the push-down cylinder 15, and a grinding head 17 is provided at the rotating end of the rotary motor 16. When the clamping plate at the tail end clamps the pipe fitting, the push-down cylinder drives the rotary motor to move downward until the grinding head extends to the upper end of the pipe fitting, and then the pipe fitting is transferred to the clamping block and the auxiliary clamping block for clamping, thereby improving the firmness of the clamping of the pipe fitting, and the burr removal at the end is completed by driving the grinding head to rotate by the rotary motor.

[0026] The working principle of the above embodiment is:

[0027] The clamping assembly is driven to move to the far left by the screw rod device, and at the same time, the clamping plates of the clamping assembly are in an open and closed state. The protruding ends of the two clamping plates at the head end will move to both sides of the pipe fitting, and the long plate will be driven to move by the push cylinder, and the long plate will drive the upper rack to retreat, and at the same time, the lower rack will be driven forward by the gear, so that the two clamping plates will clamp the pipe fitting, and then the clamping assembly is driven to move to the right by the screw rod device, and the two clamping plates at the head end will place the pipe fitting between the active plate and the auxiliary plate, and then cooperate with the push cylinder to drive the push plate to move, so that the active plate The movable plate and the auxiliary movable plate clamp and fix the pipe fitting to achieve the pre-waiting effect. Then the screw device drives the clamping assembly to reciprocate, so that the second set of clamps moves to the pipe fitting position and clamps it through the principle of the clamping assembly. At the same time, the push cylinder drives the push plate to reciprocate to complete the clamping and loosening of the pipe fitting. Therefore, the second set of clamps will move the pipe fitting to between the first set of L-shaped clamps, and through the movement of the push plate, the grinding head of the grinding device can be extended to the hole of the pipe fitting to complete the grinding operation. The third set of clamps will move the pipe fitting to the clamping position. The pipe is clamped and fixed in the holding cylinder, and the forward cylinder drives the fixed rack to reciprocate, thereby driving the rotating shaft to rotate through the rotating gear. Among them, the guide rod and the guide block can limit the fixed rack to avoid deviation during the movement. Therefore, under the rotation of the rotating shaft, the clamping cylinder can be driven to rotate, thereby adjusting the direction of the pipe fitting, and then the pipe fitting with adjusted direction is transferred to the second group of L-shaped clamping plates for clamping through the fourth group of clamping plates, and the hole deburring operation is completed through the grinding device, and then the fifth group of clamping plates transfers the pipe fitting to the shifting block The pipe is clamped and fixed between the counter-clamping block and the auxiliary moving block and waits in advance until the sixth set of clamps transfers the pipe fitting to between the clamping block and the auxiliary clamping block, and then the pipe fitting is clamped by the tail end clamp. During the clamping process, the rotary motor is driven downward by the push-down cylinder to move the grinding head to the upper port of the pipe fitting to complete the grinding, and then the pipe fitting is transferred out through the tail end clamp, thereby driving the pipe fitting to move one level at a time to complete the deburring treatment on the inside of the hole, and at the same time playing the role of automatic loading and unloading, thereby realizing automatic deburring and improving work and production efficiency.
