Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a deburring device for the inner wall of pipe fittings. Background Technology

[0002] When processing pipe fittings, it is necessary to remove burrs from the inner wall of the drilled holes. This deburring process requires manual deburring by holding a brush head and inserting it into the pipe fitting. Manual deburring is very inefficient and it is difficult to remove burrs completely, which seriously affects the production of pipe fittings. If the burrs are not removed completely, it will also cause trouble for the next assembly work and affect the accuracy of the pipe fitting after assembly. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a device for deburring the inner wall of pipe fittings.

[0004] The deburring device for the inner wall of pipe fittings provided by this utility model adopts the following technical solution:

[0005] A deburring device for the inner wall of pipe fittings includes a base, a fixed frame, a reciprocating mechanism, a rotating mechanism, a grinding mechanism, and a three-jaw clamp. The rotating mechanism is disposed at the bottom of the base, the fixed frame is disposed on the base, the reciprocating mechanism is disposed on the fixed frame, the reciprocating mechanism drives the grinding mechanism to reciprocate in the vertical direction, and the rotating mechanism is disposed on the base and drives the three-jaw clamp to rotate.

[0006] Preferably, the grinding mechanism includes a connecting frame, a motor, a drive wheel, a belt, a driven wheel, a sleeve, a rotating shaft, and a grinding head. The connecting frame is connected to a reciprocating mechanism. The motor is mounted on the connecting frame, and its output end is connected to the drive wheel. The drive wheel and the driven wheel are driven by the belt. The end of the rotating shaft is connected to the driven wheel. The rotating shaft passes through the sleeve and has two sets of bearings inside. The rotating shaft is rotatably connected to the sleeve through the two sets of bearings. The end of the rotating shaft is connected to the grinding head.

[0007] Preferably, the grinding mechanism further includes a second driving wheel, a second belt, a second driven wheel, a second sleeve, a second rotating shaft, and a second grinding head. The second driving wheel is spaced apart from the first driving wheel at the output end of the motor. The second driving wheel is driven by the second driven wheel through the second belt. The first belt and the second belt are arranged alternately. One end of the second rotating shaft is connected to the second driven wheel. The second rotating shaft is rotatably connected to the second sleeve. The other end of the second rotating shaft is connected to the second grinding head.

[0008] Preferably, the connecting frame has a waist-shaped groove, and both the first rotating shaft and the second rotating shaft pass through the waist-shaped groove. Both the first sleeve and the second sleeve are provided with connecting plates at their tops, and the connecting plates are detachably connected to the bottom of the connecting frame.

[0009] Preferably, the connecting frame is provided with two sets of round pins, and the tops of the two sets of round pins are respectively rotatably connected to tension wheel one and tension wheel two. Tension wheel one abuts against belt one, and tension wheel two abuts against belt two.

[0010] Preferably, the connecting frame has two sets of long slots in the shape of the number eight, and the round pin is slidably disposed in the long slots.

[0011] Preferably, the reciprocating mechanism includes a fixed plate, a cylinder, a slide rail, and a slider. The fixed plate and the slide rail are both welded to a fixed frame. The cylinder is mounted on the fixed plate, and the output end of the cylinder is connected to the connecting frame. The slider is fixed to the back of the connecting frame and slides in cooperation with the slide rail.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. After the motor starts, the motor output drives the first and second drive wheels to rotate, and the first and second shafts rotate accordingly. The grinding head at the bottom also rotates at high speed. The reciprocating mechanism drives the connecting frame to move up and down, thereby realizing the deburring operation of the grinding head on the inner wall of the pipe. This grinding method is significantly more efficient than manual operation and has a better deburring effect.

[0014] 2. The connecting plate is detachably connected to the bottom of the connecting frame. By adjusting the position of the connecting plate at the bottom of the connecting frame, the distance between the first and second rotating shafts can be adjusted. When the pipe diameter is small, the distance between the first and second rotating shafts is relatively small, and when the pipe diameter is large, the distance between the first and second rotating shafts is relatively large, thereby enabling the grinding of the inner wall of pipes with different diameters, making it more practical.

[0015] 3. The round pin is slidably set in the long groove. The round pin can slide to a suitable position in the long groove and be fixed by bolts, so as to achieve the tightness of tensioning wheel one or tensioning wheel two against belt one or belt two, ensuring the stability of belt drive.

[0024] This utility model discloses a device for deburring the inner wall of pipe fittings. (Refer to...) Figures 1-4A pipe fitting deburring device includes a base 1, a fixed frame 2, a reciprocating mechanism 3, a rotating mechanism 4, a grinding mechanism 5, and a three-jaw clamp 6.

The three-jaw clamp 6 is used to fix the pipe fitting to be processed. The pipe fitting is vertically clamped on the base 1, and the opening is aligned with the grinding mechanism 5.

[0025] The grinding mechanism 5 includes a connecting frame 501, a motor 502, a first drive wheel 503, a first belt 504, a first driven wheel 505, a first sleeve 506, a first rotating shaft 507, and a first grinding head 508.

By adjusting the position of the connecting plate at the bottom of the connecting frame 501, the distance between the first rotating shaft 507 and the second rotating shaft 513 can be adjusted. When the pipe diameter is small, the distance between the first rotating shaft 507 and the second rotating shaft 513 is relatively small, and when the pipe diameter is large, the distance between the first rotating shaft 507 and the second rotating shaft 513 is relatively large, thereby enabling the grinding of the inner wall of pipes with different diameters, making it more practical.
