Description

Technical Field

[0001] This invention relates to the field of door and window processing technology, and more particularly to an auxiliary device for door and window processing. Background Technology

[0002] Currently, when producing sliding door and window tracks, since the tracks are usually made by extrusion molding, the extruded tracks need to be cut into multiple sections by a cutting machine. Then, workers use files or grinders to grind the ends of the cut tracks to avoid burrs. However, since the cross-sections of the ends of the tracks are usually "mountain" shaped, the process of grinding the edges with files or grinders is quite cumbersome. To solve the above problems, we propose an auxiliary device for door and window processing. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary device for door and window processing that is simple to operate and convenient for grinding "mountain" shaped cross sections.

[0004] This invention is achieved through the following measures: An auxiliary device for door and window processing, characterized in that it includes a workbench, on which a grinding mechanism is provided; The grinding mechanism includes a support plate disposed on the lower side of the workbench. A rotating shaft is disposed on the support plate, and a vertically placed hexahedron is disposed on the rotating shaft. Edge grinding component one, edge grinding component two, and edge grinding component three are evenly disposed on the outer side of the hexahedron. Specifically, edge grinding component one, edge grinding component two, and edge grinding component three are spaced apart on the six outer side of the hexahedron. A crank handle connected to the rotating shaft is also rotatably disposed on the support plate. The rotating shaft can be rotated by the crank handle, thereby rotating the hexahedron.

[0005] The invention also has the following specific features: The edge grinding assembly includes a portal frame fixed to the hexahedron by bolts. An upper auxiliary plate is provided on the upper side plate of the portal frame, a lower horizontal plate is provided between the portal frames, and a lower auxiliary plate is provided on the lower horizontal plate. An upper grinding plate and a lower grinding plate are respectively hinged to the inner ends of the upper auxiliary plate and the lower auxiliary plate facing the slide rail. Several springs are provided between the upper auxiliary plate and the upper grinding plate, and between the lower auxiliary plate and the lower grinding plate. One end of the spring is provided on the upper auxiliary plate or the lower auxiliary plate, and the other end of the spring is provided on the upper grinding plate or the lower grinding plate. Under the action of the springs, the upper grinding plate and the lower grinding plate form a V shape, and sandpaper is provided on the inner surfaces of the upper grinding plate and the lower grinding plate facing each other. The edge grinding assembly is used to grind the outer upper horizontal side and the outer lower horizontal side of the slide rail end face.

[0006] The second edge grinding assembly includes a portal frame two fixed to the hexahedron by bolts. The portal frame two is provided with a pair of vertical edge grinding parts. The second edge grinding assembly is used to grind the four inner vertical side edges of the inner side of the slide rail end face. The vertical edge grinding part includes a downward extension plate facing the hexahedron on the upper side plate of the portal frame two. A middle plate is provided in the middle of the downward extension plate. A left grinding plate and a right grinding plate are respectively hinged to both sides of the downward extension plate. A spring two is provided between the left grinding plate one and the right grinding plate one and the downward extension plate. Under the action of the spring two, the left grinding plate one and the right grinding plate one form a V-shaped structure. Sandpaper is provided on the outer surfaces of the left grinding plate one and the right grinding plate one facing each other.

[0007] The edge grinding assembly three includes a portal frame three fixed to the hexahedron by bolts. The portal frame three is provided with an outer edge grinding part and a lower edge grinding part. The outer edge grinding part is used to grind the two outer vertical side edges on the outer side of the slide rail end face. The lower edge grinding part is used to grind the two inner lower horizontal side edges on the inner side of the slide rail end face. The outer grinding part includes a left auxiliary plate and a right auxiliary plate respectively disposed on the vertical side plates on both sides of the portal frame. The left auxiliary plate and the right auxiliary plate are respectively hinged to the inner ends facing the slide rail. Several sets of springs are disposed between the left auxiliary plate and the left grinding plate and between the right auxiliary plate and the right grinding plate. Under the action of the springs, the left grinding plate and the right grinding plate form a V-shaped structure. Sandpaper is disposed on the outer surfaces of the left grinding plate and the right grinding plate. The lower grinding section includes a pair of L-shaped brackets extending towards the hexahedron on the upper side plate of the portal frame three. The pair of L-shaped brackets are located on the inner side of the upper side plate of the portal frame three facing the slide rail. Each pair of L-shaped brackets is hinged with a beveled grinding plate. A spring four is provided between the beveled grinding plate and the upper side plate of the portal frame three. One end of the spring four is located on the beveled grinding plate, and the other end of the spring four is located on the upper side plate of the portal frame three. Under the action of the spring four, the outer end of the beveled grinding plate away from the hinge is inclined towards the hexahedron. Sandpaper is provided on the lower side of the beveled grinding plate facing the hexahedron. The two beveled grinding plates are used to grind the two inner lower horizontal sides of the slide rail end face.

[0008] The worktable is provided with working holes that mate with the first, second, and third edge grinding components. When the hexahedron is rotated, the first, second, and third edge grinding components rotate sequentially into the working holes. The first, second, or third edge grinding components that enter the working holes are all located on the worktable and their heights mate with the slide rails placed on the worktable. That is, when the slide rails are pushed toward the grinding mechanism, their end faces can be ground by the corresponding first, second, or third edge grinding components. The entire grinding process is achieved by the pressure of the corresponding springs and the movement of the slide rails.

[0009] The workbench is also equipped with a holding mechanism; The clamping mechanism includes a circular groove on the worktable, a turntable rotatably mounted in the circular groove, and a pair of clamping plates on the turntable that cooperate with the slide rail. In use, the slide rail is clamped between the two clamping plates. A left hole and a right hole are provided between the circular groove and the grinding mechanism, penetrating the worktable. The left hole and the right hole are located on both sides of the slide rail. A left limiting rod and a right limiting rod, which cooperate and limit the slide rail, are slidably mounted in the left hole and the right hole, respectively. When one side of the slide rail abuts against the side of the left limiting rod or the right limiting rod, the slide rail is pushed forward, and the end of the slide rail just enters the edge grinding assembly one, edge grinding assembly two, or edge grinding assembly three, thereby smoothly performing grinding. Obviously, the slide rail is located between the left limiting rod and the right limiting rod.

[0010] Both the left and right limit rods are equipped with racks. A second rotating shaft is mounted on the lower side of the worktable via a corresponding bracket. The second rotating shaft is equipped with a second gear and a pair of first gears that mesh with the corresponding side racks. A third rotating shaft is mounted on the lower side of the worktable via a corresponding bracket. A third gear that meshes with the second gear is mounted on the third rotating shaft. A first bevel gear is mounted on the end of the third rotating shaft near the circular groove. A fourth rotating shaft is coaxially fixed on the turntable. The lower end of the fourth rotating shaft passes through the worktable and is equipped with a second bevel gear that meshes with the first bevel gear. The left limiting rod and the right limiting rod are offset vertically relative to the worktable. That is, when the upper end of the left limiting rod is higher than the upper side of the worktable, the upper end of the right limiting rod is not higher than the upper side of the worktable, and vice versa. The fourth rotating shaft rotates on the worktable along with the turntable. After grinding one end of the slide rail, the slide rail is manually pulled back to disengage from the first, second, or third grinding assembly. The slide rail is then rotated, causing the turntable to rotate, which in turn drives the fourth rotating shaft to rotate. Then, the first and second bevel gears work together to drive the third rotating shaft to rotate. After that, the gears work together with the rack to cause the left limit rod to rise and the right limit rod to fall, or vice versa. After the slide rail rotates 180 degrees, the other side rests against the corresponding left or right limit rod. Then, the slide rail is pushed forward to grind the other end.

[0011] A pair of extension tubes are provided on the lower side of the worktable, which are respectively slidably engaged with the left and right limiting rods. The extension tubes further ensure the stability of the left or right limiting rod when it is not higher than the upper side of the worktable, thus preventing it from detaching from the entire device.

[0012] The vertical side of the hexahedron away from the first pivot is provided with a six-sided groove that matches the structure of the hexahedron. Three sets of electromagnets are provided in the six-sided grooves. The three sets of electromagnets are respectively close to the outer side of the hexahedron that is not provided with edge grinding component one, edge grinding component two, or edge grinding component three. It should be noted that the materials of the hexahedron and edge grinding component one, edge grinding component two, and edge grinding component three must be ensured not to affect the normal operation of the electromagnets. T-shaped grooves are provided on both end faces of the working hole. Both T-shaped grooves extend through the two sides of the worktable. T-shaped sliders are slidably arranged in the T-shaped grooves. Limiting blocks that cooperate with the hexahedron are provided on the T-shaped sliders. The side of the limiting block facing the hexahedron is an inclined side that cooperates with the outer side of the hexahedron. A metal plate that cooperates with the electromagnet is provided on the inclined side. Under the action of the electromagnet, the limiting blocks on both sides slide and fit against the outer side of the hexahedron that is not provided with edge grinding component one, edge grinding component two, or edge grinding component three, thereby limiting the hexahedron and ensuring that the slide rail can smoothly slide into edge grinding component one, edge grinding component two, or edge grinding component three for grinding.

[0013] On both sides of the workbench, there are auxiliary plates provided by a pair of brackets. Spring 5 is provided on the auxiliary plates. The other end of spring 5 is provided on the limiting block. When the electromagnet is de-energized, the limiting block is reset under the action of spring 5. Then the hexahedron can be rotated smoothly to replace edge grinding assembly 1, edge grinding assembly 2 or edge grinding assembly 3 to grind other parts of the slide rail. In addition, several support legs are provided on the lower side of the workbench.

[0014] During operation, the slide rail is positioned between the two supporting plates. Then, the slide rail is rotated so that one side abuts against the right limiting rod. At this point, the upper surface of the left limiting rod is lower than the upper side of the worktable. The hexahedron is then manually rotated using the crank handle, positioning the first grinding assembly within the working hole. The electromagnet is then energized. Under magnetic force, the limiting blocks on both sides abut against the two sides of the corresponding hexahedron that are not equipped with grinding assembly one, grinding assembly two, or grinding assembly three, thus limiting and aligning the hexahedron. The slide rail is then pushed into the first grinding assembly. During this movement, the upper grinding plate and... The lower grinding plate grinds the upper and lower outer horizontal sides of the slide rail. After completion, manually pull the slide rail backward to disengage from the first, second, or third grinding assembly. Then rotate the slide rail, which drives the turntable to rotate, thereby driving the fourth rotating shaft to rotate. Then, through the cooperation of the first and second bevel gears, the third rotating shaft is driven to rotate. Then, through the cooperation of the gears and the rack, the left limit rod rises and the right limit rod falls, or the right limit rod rises and the left limit rod falls. After the slide rail rotates 180 degrees, the other side rests on the corresponding left or right limit rod. Then push the slide rail forward to grind the other end. After the electromagnet is de-energized, the limiting block is reset under the action of the spring five, and then the hexahedron can be rotated smoothly. Replace the edge grinding assembly two, and the other steps are as described above. Grind the four inner vertical sides of the slide rail end face. Then change the edge grinding assembly three, and grind the two outer vertical sides of the slide rail end face through the outer edge grinding part, and grind the inner lower horizontal side of the slide rail end face through the lower edge grinding part.

[0015] The beneficial effects of this invention are as follows: The design of the grinding mechanism of this invention avoids the laboriousness of manual grinding with a file and the cumbersome process of grinding with a grinding machine. This invention creatively applies a rotatable hexahedral structure, with grinding component one, grinding component two, or grinding component three respectively installed on the outer surface of the hexahedron. By rotating the hexahedron, grinding of different parts of the slide rail can be achieved, which not only saves space but also improves work efficiency. In addition, the design of the holding mechanism makes it easy to align the slide rail with the grinding mechanism, further improving work efficiency. Attached Figure Description

[0028] The grinding assembly includes a portal frame 27 fixed to the hexahedron 5 by bolts. The portal frame 27 is provided with an outer grinding part and a lower grinding part. The outer grinding part is used to grind the two outer vertical side edges 38 on the outer side of the end face of the slide rail 2, and the lower grinding part is used to grind the two inner lower horizontal side edges 40 on the inner side of the end face of the slide rail 2. The outer grinding edge includes a left auxiliary plate and a right auxiliary plate respectively set on the vertical side plates on both sides of the portal frame 27. The left auxiliary plate and the right auxiliary plate are respectively hinged to the inner ends facing the slide rail 2. Several sets of springs are set between the left auxiliary plate and the left grinding plate 23 and between the right auxiliary plate and the right grinding plate 28. Under the action of the springs, the left grinding plate 23 and the right grinding plate 28 form a V-shaped structure. Sandpaper is set on the outer surfaces of the left grinding plate 23 and the right grinding plate 28 facing each other. The lower grinding edge includes a pair of L-shaped brackets 26 extending toward the hexahedron 5 on the upper side plate of the portal frame 3 27. The pair of L-shaped brackets 26 are located on the inner side of the upper side plate of the portal frame 3 27 facing the slide rail 2. Each pair of L-shaped brackets 26 is hinged with a beveled grinding plate 25. A spring 4 24 is located between the beveled grinding plate 25 and the upper side plate of the portal frame 3 27. One end of the spring 4 24 is located on the beveled grinding plate 25, and the other end of the spring 4 24 is located on the upper side plate of the portal frame 3 27. Under the action of the spring 4 24, the outer end of the beveled grinding plate 25 away from the hinge is inclined toward the hexahedron 5. Sandpaper is located on the lower side of the beveled grinding plate 25 facing the hexahedron 5. The two beveled grinding plates 25 are used to grind the two inner lower horizontal sides 40 of the end face of the slide rail 2.

[0029] The workbench 1 is provided with working holes 8 that mate with the first, second and third edge grinding components. When the hexahedron 5 is rotated, the first, second and third edge grinding components rotate into the working holes 8 in sequence. The first, second or third edge grinding components that enter the working holes 8 are all located on the workbench 1 and their heights are matched with the slide rails 2 placed on the workbench 1. That is, when the slide rails 2 are pushed toward the grinding mechanism, their end faces can be ground by the corresponding first, second or third edge grinding components. The entire grinding process is achieved by the pressure of the corresponding springs and the movement of the slide rails 2.

[0030] A blessing mechanism is also installed on workbench 1; The clamping mechanism includes a circular groove on the worktable 1, a turntable rotatably mounted in the circular groove, and a pair of clamping plates 3 that cooperate with the slide rail 2 on the turntable. In use, the slide rail 2 is clamped between the two clamping plates 3. A left hole and a right hole are provided between the circular groove and the grinding mechanism, which pass through the worktable 1. The left hole and the right hole are located on both sides of the slide rail 2. A left limiting rod 9 and a right limiting rod 4 that cooperate and limit the slide rail 2 are slidably mounted in the left hole and the right hole, respectively. When one side of the slide rail 2 abuts against the side of the left limiting rod 9 or the right limiting rod 4, the slide rail 2 is pushed forward, and the end of the slide rail 2 just enters the edge grinding assembly one, edge grinding assembly two, or edge grinding assembly three, so that grinding can be carried out smoothly. Obviously, the slide rail 2 is located between the left limiting rod 9 and the right limiting rod 4.

[0031] Both the left limit rod 9 and the right limit rod 4 are equipped with racks 12. A rotating shaft 2 is provided on the lower side of the worktable 1 via a corresponding bracket. A gear 2 11 and a pair of gears 10 that mesh with the corresponding racks 12 are provided on the rotating shaft 2. A rotating shaft 3 is provided on the lower side of the worktable 1 via a corresponding bracket. A gear 32 that meshes with gear 2 11 is provided on the rotating shaft 3.

The left limit rod 9 and the right limit rod 4 are staggered vertically relative to the worktable 1. That is, when the upper end of the left limit rod 9 is higher than the upper side of the worktable 1, the upper end of the right limit rod 4 is not higher than the upper side of the worktable 1, and vice versa. The fourth rotating shaft rotates on the worktable 1 along with the turntable. After grinding one end of the slide rail 2, manually pull the slide rail 2 backward to disengage it from the first, second, or third grinding components. Then rotate the slide rail 2, which drives the turntable to rotate, thereby driving the fourth rotating shaft to rotate. Then, through the cooperation of bevel gear 1 30 and bevel gear 2 31, the third rotating shaft is driven to rotate. Then, through the cooperation of the gear and rack 12, the left limit rod 9 rises and the right limit rod 4 falls, or the right limit rod 4 rises and the left limit rod 9 falls. After the slide rail 2 rotates 180 degrees, the other side rests on the corresponding left limit rod 9 or right limit rod 4. Then push the slide rail 2 forward to grind the other end.

[0032] A pair of extension tubes 33 are provided on the lower side of the worktable 1, which are respectively slidably engaged with the left limit rod 9 and the right limit rod 4. The extension tubes 33 further ensure the stability of the left limit rod 9 or the right limit rod 4 when they are not higher than the upper side of the worktable 1, thus preventing them from detaching from the entire device.

[0033] The vertical side of the hexahedron 5 away from the pivot 6 is provided with a six-sided groove that matches the structure of the hexahedron 5. Three sets of electromagnets 29 are provided in the six-sided groove. The three sets of electromagnets 29 are respectively close to the side of the hexahedron 5 that is not provided with edge grinding component 1, edge grinding component 2 or edge grinding component 3. It should be noted that the materials of the hexahedron 5 and edge grinding component 1, edge grinding component 2 and edge grinding component 3 must be ensured not to affect the normal operation of the electromagnets 29. T-shaped grooves are provided on both end faces of the working hole 8. Both T-shaped grooves pass through the two sides of the worktable 1. T-shaped sliders are slidably installed in the T-shaped grooves. Limiting blocks 7 that cooperate with hexahedron 5 are provided on the T-shaped sliders. The side of the limiting block 7 facing the hexahedron 5 is an inclined side that cooperates with the outer side of the hexahedron 5. A metal plate that cooperates with electromagnet 29 is provided on the inclined side. Under the action of electromagnet 29, the two limiting blocks 7 slide and fit against the outer side of the hexahedron 5 that is not provided with edge grinding component one, edge grinding component two or edge grinding component three, thereby limiting the hexahedron 5 and ensuring that the slide rail 2 can smoothly slide into edge grinding component one, edge grinding component two or edge grinding component three for grinding.

[0034] On both sides of the workbench 1, there are auxiliary plates 34 set by a pair of brackets. A spring 35 is set on the auxiliary plate 34. The other end of the spring 35 is set on the limit block 7. When the electromagnet 29 is de-energized, the limit block 7 is reset under the action of the spring 35. Then the hexahedron 5 can be rotated smoothly to replace the edge grinding assembly one, edge grinding assembly two or edge grinding assembly three to grind other parts of the slide rail 2. In addition, several support legs are provided on the lower side of the workbench 1.

[0035] During operation, slide rail 2 is positioned between the two support plates 3. Then, slide rail 2 is rotated so that one side abuts against the right limiting rod 4. At this point, the upper surface of the left limiting rod 9 is lower than the upper side of the worktable 1. Next, the hexahedron 5 is manually rotated using the crank handle, positioning the first grinding assembly within the working hole 8. Then, the electromagnet 29 is energized. Under magnetic force, the two limiting blocks 7 abut against the two sides of the corresponding hexahedron 5 that are not equipped with the first, second, or third grinding assembly, thus limiting and aligning the hexahedron 5. Then, slide rail 2 is pushed into the first grinding assembly. During this movement, the upper grinding plate 15 and lower grinding plate 1 in the first grinding assembly... 6. Grind the upper outer horizontal side 36 and the lower outer horizontal side 37 of the slide rail 2. After completion, manually pull the slide rail 2 backward to disengage from the grinding component one, grinding component two or grinding component three. Then rotate the slide rail 2. The slide rail 2 drives the turntable to rotate, which in turn drives the rotating shaft four to rotate. Then, through the cooperation of bevel gear one 30 and bevel gear two 31, the rotating shaft three is driven to rotate. Then, through the cooperation of the gear and rack 12, the left limit rod 9 rises and the right limit rod 4 falls, or the right limit rod 4 rises and the left limit rod 9 falls. After the slide rail 2 rotates 180 degrees, the other side rests on the corresponding left limit rod 9 or right limit rod 4. Then push the slide rail 2 forward to grind the other end. After the power is turned off, the electromagnet 29 is de-energized, and the limit block 7 is reset under the action of the spring 35. Then the hexahedron 5 can be rotated smoothly. Replace the edge grinding assembly 2 and proceed with other steps. Grind the four inner vertical sides 39 on the inner side of the slide rail 2 end face. Then change the edge grinding assembly 3. Grind the two outer vertical sides 38 on the outer side of the slide rail 2 end face through the outer edge grinding part, and grind the inner lower horizontal side 40 on the inner side of the slide rail 2 end face through the lower edge grinding part.

[0036] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
