Description

Technical Field

[0001] The utility model relates to the technical field of plate welding, in particular to an automatic plate welding seam grinding machine. Background Art

[0002] In industrial production, it is often necessary to align and weld two plates along their edges to form a whole for use. After the two plates are welded, a weld seam will be formed at the weld edge. Weld slag is easily retained at the weld seam, which causes the weld area to be uneven and affects the overall quality after welding. Therefore, the weld area needs to be processed by grinding to improve the overall smoothness and processing quality.

[0003] In this regard, the current welding seams are generally ground by manually moving a handheld angle grinder along the weld seam, or using a bench grinder. However, the grinding part of today's grinders is generally only a single grinding head. When facing larger plates, such grinders are prone to generate strong vibrations during the grinding process, causing the weld seam to shift, which in turn requires workers to make repeated adjustments, resulting in low efficiency, and therefore needs to be improved.

DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments, wherein the same components are denoted by the same reference numerals.

[0030] like Figure 1-6 As shown, an automatic plate weld grinding machine includes: a frame 1, a grinding station 2 is formed along the length direction of the frame 1, and in this embodiment, a groove 3 is formed on the frame 1 corresponding to the grinding station 2 to prevent particles in the grinding area from causing additional damage to the plate after compression.

[0031] The two sides of the frame 1 corresponding to the grinding station 2 are open, thereby facilitating the entry of the plate into the grinding station 2.

[0032] Furthermore, there are two pressing plates 4, which are symmetrically arranged along the grinding station 2. The two pressing plates 4 are used to press and fix the plate after it is placed on the grinding station 2, so as to avoid the plate from being offset during the processing, thereby improving the stability of the plate.

[0033] Furthermore, the frame 1 is provided with a first lifting component 5 corresponding to the pressure plate 4. The first lifting component 5 is connected to the pressure plate 4 and is used to drive the pressure plate 4 to lift and lower. In this embodiment, the first lifting component 5 is a lifting cylinder. The frame 1 is provided with a lifting seat 23 on both sides corresponding to the grinding station 2. The lifting cylinder is arranged in the lifting seat 23, and a clamping block 19 is provided at the output end of the lifting cylinder. A fixed seat 17 is provided on the pressure plate 4. The fixed seat 17 is fixedly connected to the pressure plate 4 by welding. A through groove 18 is provided on the fixed seat 17 in the horizontal direction. The first lifting component 5 includes a clamping block 19. The clamping block 19 slides with the through groove 18 in the horizontal direction and is clamped and limited with the through groove 18 in the height direction.

[0034] When in use, the block 19 is slidably engaged with the through slot 18 in the horizontal direction, and the upper end of the block 19 is fixed to the output end of the lifting cylinder, thereby driving the lifting cylinder to realize the lifting operation of the pressing plate 4. At the same time, the operator can adapt to the use of plates of different thicknesses by adjusting the lifting of the pressing plate 4.

[0035] Furthermore, in order to improve the stability of the movement of the pressing plate 4 , the frame 1 is provided with a limiting groove 16 corresponding to the pressing plate 4 , and one end of the pressing plate 4 is limited and slidable with the limiting groove 16 .

[0036] Furthermore, it also includes a grinding device, which includes a displacement seat 6 and a drive unit 7. An installation interval 24 is formed between the two lifting seats 23. The displacement seat 6 is arranged corresponding to the installation interval 24, and the displacement seat 6 includes a mounting surface arranged on the top of the lifting seat 23 on one side. The drive unit 7 includes a displacement motor 21 connected to the displacement seat 6 and a drive rack 22 arranged on the frame 1. The drive rack 22 extends along the length direction of the grinding station 2. The output end of the displacement motor 21 is provided with a gear and is meshed with the drive rack 22.

[0037] Furthermore, in order to limit the moving direction of the displacement seat 6, in this embodiment, a guide rail 20 is provided on the lifting seat 23 along the length direction of the grinding station 2 and is limited and slidable with the displacement seat 6.

[0038] When in use, the displacement motor 21 drives the gear to rotate, thereby cooperating with the driving rack 22 to achieve linear driving of the displacement seat 6.

[0039] Furthermore, the displacement seat 6 is provided with a grinding wheel 8 corresponding to the grinding station 2 and an auxiliary wheel 9 is symmetrically provided in the front and rear directions of the grinding wheel 8. The grinding wheel 8 and the auxiliary wheel 9 are both rotatably connected to the displacement seat 6, and the auxiliary wheel 9 is arranged at the same level as the grinding wheel 8. Therefore, during the grinding process, the auxiliary wheels 9 on both sides can respectively press the plate in front and behind the grinding wheel 8 to further avoid the plate deviation caused by grinding, so as to improve the stability of the plate.

[0040] Furthermore, in order to adapt to the use of plates of different heights, a second lifting component 13 is provided on the displacement seat 6 and a mounting plate 14 is connected through the second lifting component 13. In this embodiment, the second lifting component 13 is specifically an adjustment cylinder, and the grinding wheel 8 is rotatably connected to the mounting plate 14.

[0041] By setting the second lifting assembly 13, the height of the mounting plate 14 can be adjusted according to the specific thickness of the plate, and then the height of the grinding wheel 8 can be adjusted to adapt to the use of plates of different heights.

[0042] Specifically, the auxiliary wheel 9 includes a middle rod 11 and contact pieces 12 symmetrically arranged at both ends of the middle rod 11. The contact pieces 12 on both sides are fixedly connected to the middle rod 11, and the two contact pieces 12 are symmetrically arranged relative to the grinding wheel 8. Furthermore, the auxiliary wheel 9 also includes a mounting seat 15. In this embodiment, a rotating rod is provided on the side of the contact piece 12 and is rotatably connected to the mounting seat 15 through the rotating rod. At the same time, the mounting seat 15 is detachably connected to the mounting plate 14. The detachability is specifically achieved by bolts to facilitate maintenance of the auxiliary wheel 9.

[0043] On the one hand, the contact pieces 12 on both sides of the middle rod 11 can reduce the contact with the weld area, thereby reducing the resistance of the auxiliary wheel 9 when moving. At the same time, since the contact with the weld area is reduced, the contact with the slag in the weld area can be reduced, thereby improving the smoothness of the movement of the auxiliary wheel 9. At the same time, the symmetrical setting can assist in positioning the grinding wheel 8.

[0044] Furthermore, a driving motor 10 connected to the grinding wheel 8 is provided on the displacement seat 6, and the driving motor 10 is used to drive the grinding wheel 8 to rotate.

[0045] Specifically, the output end of the driving motor 10 is provided with a linkage mechanism 25 and is connected to the grinding wheel 8 through the linkage mechanism 25. The driving motor 10 and the linkage mechanism 25 are symmetrically arranged along the displacement seat 6, thereby being able to adjust the force center of gravity of the displacement seat 6, making the movement of the displacement seat 6 more stable.

[0046] Specifically, the linkage mechanism 25 includes a linkage rod 26 and a first pulley 27. The linkage rod 26 is rotatably connected to the displacement seat 6. A second pulley 28 and a third pulley 29 are respectively provided at both ends of the linkage rod 26. A fourth pulley 30 is provided at the output end of the drive motor 10 and is connected to the second pulley 28 by a belt. The first pulley 27 is rotatably connected to the displacement seat 6, and the first pulley 27 is connected to the third pulley 29 through a belt. The first pulley 27 is coaxially provided with a fifth pulley 31. The rotation of the first pulley 27 drives the fifth pulley 31 to rotate at the same time. The fifth pulley 31 is connected to the grinding wheel 8 through a belt.

[0047] When in use, the output end of the driving motor 10 drives the fourth pulley 30 to rotate, further drives the second pulley 28 to rotate through the belt, and further drives the third pulley 29 to rotate through the linkage rod 26. After the third pulley 29 rotates, it drives the first pulley 27 to rotate through the belt, and further drives the grinding wheel 8 to rotate through the fifth pulley 31 to achieve the grinding effect on the weld.

[0048] In this embodiment, the belt corresponding to the grinding wheel 8 is a grinding belt, and a grinding surface is formed on its surface to complete the grinding of the weld. In other embodiments, a grinding ring can also be provided on the outer surface of the grinding wheel 8 to achieve a grinding effect.

[0049] By linking multiple pulleys and belts to achieve multi-stage transmission, the installation range of the drive motor 10 can be expanded, making the overall spatial structure more reasonable.

[0050] Furthermore, the displacement seat 6 is provided with a tensioning mechanism 32 corresponding to the belt. The tensioning mechanism 32 includes a tensioning wheel 33 and a tensioning rod 34. The two ends of the tensioning rod 34 are respectively rotatably connected to the displacement seat 6 and the tensioning wheel 33. The tensioning wheel 33 is used to resist the belt to keep the belt taut.

[0051] In this embodiment, since a second lifting assembly 13 is provided, the tensioning mechanism 32 located at the grinding wheel 8 is also provided with a control cylinder 35, which is connected to one end of the tensioning rod 34 to control the rotation of the tensioning rod 34. Therefore, after the second lifting assembly 13 adjusts the height of the mounting plate 14, the tensioning rod 34 can be controlled to rotate by the control cylinder 35 to ensure the tension of the belt at this position.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
