Description

Technical Field

[0001] The invention relates to the technical field of equipment for producing fire doors, in particular to an installation, clamping and welding device for producing fire doors. Background Art

[0002] Fire doors are an important fire separation facility. They can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. Fire doors can be divided into wooden fire doors, steel fire doors, steel-wood fire doors and other materials according to their materials. Fire door frames can also be made of a variety of materials, including wood, steel, steel-wood and other materials. In the process of making steel fire doors, the steel is first pressed into the shape of a door frame with one edge, and then the pressed steel is cut into a certain length, and the four steels cut into a fixed length are welded into a door frame. Since the size of the fire door frame is relatively large, during the welding process, the manual operation needs to be kept moving, and the steel needs to be fixed during the welding process, otherwise the door frame may be deformed due to uneven heating during the welding process. In addition, after welding one side of the door frame, the door frame needs to be turned over and the other side of the door frame needs to be welded. Therefore, the entire welding process is very time-consuming and labor-intensive and requires high technical skills from the welding master.

[0003] The door frame and door leaf panel of the steel fireproof door should be made of steel material with performance not lower than that of cold-rolled thin steel plate. The technical content disclosed in the Chinese patent document (publication number: CN106881547B, patent name: a door frame automatic rotation welding mobile car) is: this door frame automatic rotation welding mobile car, the wire feeder is vertically fixed on the mobile car, the rotation mechanism can rotate 360° back and forth, the wire feeding tube passes through the rotation mechanism and is connected to the electric welder. The wire feeding tube is supported by a supporting spring to avoid winding around the wire feeding machine. The wire feeding tube and the welding gun are connected to the welding car through the welding gun support, and the welding is rotated along the door frame. After welding for a full circle, the welding car is lifted and rotated for a circle to return the wire feeder to its original position. When the size of the door frame changes, the mobile car can be moved to adapt to various size changes and the operation is completed.

[0004] It can be seen from the above implementation scheme that the door frame automatic rotation welding mobile vehicle can move to multiple positions of the door frame to weld it, but it can only weld one side of the door frame. When the other side of the door frame needs to be welded, it is still necessary to manually turn the door frame over. Therefore, for the operator, the operation is still quite difficult. Moreover, since the door frame is heavy, it is quite laborious to move the door frame, which is also prone to cause safety accidents. Summary of the invention The invention overcomes the shortcomings of the prior art and provides a welding manipulator. Rotatable clamping components are provided on both sides of the welding manipulator. The operator only needs to install the steel on the clamping component, and the clamping component can rotate with the positioned steel to cooperate with the welding manipulator to weld the door frame. The welding manipulator mainly welds the connecting position of the steel, and the connecting position is the cross-section of the steel. Therefore, in addition to welding the connecting positions directly above and on the sides of the door frame on the clamping component, welding is also required for the connecting position on the back of the door frame. After the front door welding of the door frame is completed, the clamping component can turn the back of the door frame toward the direction of the welding manipulator. Therefore, there is no need to manually perform secondary installation of the door frame, which not only reduces the labor intensity of the operator, but also avoids the processing error caused by secondary clamping, thereby ensuring the production quality of the door frame.

DETAILED DESCRIPTION The preferred embodiments of the invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the invention, and are not used to limit the invention.

[0017] like Figures 1 to 16The installation clamping electric welding device for fire door production shown in the figure comprises a welding manipulator 2, a clamping assembly 5 is arranged on both sides of the welding manipulator 2, and both ends of the clamping assembly 5 are connected to a rotating power assembly 4; the rotating power assembly 4 comprises a rotating bracket 401, and both sides of the rotating bracket 401 are respectively connected to a rotating drive motor 404 and a rotating bearing component 402, and the rotating bearing component 402 comprises a bearing seat 4021, and the bearing seat 4021 is connected to a rotating bearing 4022, and the rotating bearing 4022 is connected to a rotating block 4023, and the rotating block 4023 is connected to the rotating drive motor 404, and the side of the rotating block 4023 away from the rotating drive motor 404 is connected to a rotating seat body 403. The clamping assembly 5 can rotate 360 ​​degrees under the drive of the rotating power assembly 4; one side of the clamping assembly 5 clamps the welding steel, and the other side of the clamping assembly 5 is provided with hollow holes and hollow slots; when the welding manipulator 2 welds the door frame composed of welding steel, the clamping assembly 5 rotates so that different welding positions of the welding steel are close to the welding manipulator 2 in sequence. The operator only needs to install the steel on the clamping assembly 5, and the clamping assembly 5 can rotate with the positioned steel to cooperate with the welding robot 2 to weld the door frame. During the production process of the steel fire door, the steel is first pressed into the shape of a door frame with one edge, and then the pressed steel is cut into a certain length, and the four steels cut to a fixed length are welded into a door frame. Therefore, the welding robot 2 mainly welds the connecting position of the steel, and the connecting position is the cross-section of the steel. Therefore, in addition to welding the connecting positions just above and on the sides of the door frame on the clamping assembly 5, the connecting positions on the back of the door frame must also be welded. After the front door welding of the door frame is completed, the clamping assembly 5 can turn the back of the door frame toward the direction of the welding robot. Therefore, there is no need to manually perform a secondary installation of the door frame, which not only reduces the labor intensity of the operator, but also avoids the processing errors caused by secondary clamping, thereby ensuring the production quality of the door frame.

[0018] The welding manipulator 2 is arranged in the middle of the base 1, and screens 3 are arranged on both sides of the welding manipulator 2. The clamping assembly 5 is arranged on the side of the screen 3 away from the welding manipulator 2; the screen 3 includes a baffle 303, and the two sides of the baffle 303 are connected to the lifting slide rail 302 and the lifting cylinder 301; when the steel is still in the clamping process, the baffle 303 of the screen 3 rises to block the welding manipulator 2, and the rise of the baffle 303 will also trigger the proximity switch located at the top of the screen 3, and the proximity switch is associated with the switch of the welding manipulator 2. When the proximity switch is triggered, the welding manipulator 2 is in a closed state, and the welding manipulator 2 will not move at this time, so as to avoid the operator being accidentally injured by the welding manipulator 2 when installing the steel, thereby ensuring the safety of the operator. When the steel is clamped, the baffle 303 drops, and the welding manipulator 2 can weld the door frame at this time.

[0019] The clamping assembly 5 includes a clamping bottom frame 501, and the first transverse clamping module 503, the second transverse clamping module 504 and the third transverse clamping module 505 are sequentially arranged in the X-axis direction of the clamping bottom frame 501; the first transverse clamping module 503 is fixed to one side of the clamping assembly 5, and the second transverse clamping module 504 and the third transverse clamping module 505 can slide in the X-axis direction of the clamping bottom frame 501. Therefore, according to door frames with different height directions, the steel materials composed of door frames with different height directions can be clamped by adjusting the positions of the second transverse clamping module 504 and the third transverse clamping module 505.

[0020] The first transverse clamping module 503 includes two first pneumatic clamping tables 506, one of which is fixed at one end of the first transverse clamping module 503, and the other first pneumatic clamping table 506 is slidably connected to the first transverse clamping module 503; the third transverse clamping module 505 includes a second movable plate 5051 and two first pneumatic clamping tables 506, one of which is fixed at one end of the second movable plate 5051, and the other first pneumatic clamping table 506 is slidably connected to the second movable plate 5051; the second transverse clamping module 504 includes a first movable plate 5041 and two second pneumatic clamping tables 507, one of which is fixed at one end of the first movable plate 5041, and the other second pneumatic clamping table 507 is slidably connected to the first movable plate 5041. Therefore, according to the door frames with different widths, the steel materials composed of the door frames with different widths can be clamped by adjusting the positions of the movable first pneumatic clamping platform 506 and the second pneumatic clamping platform 507.

[0021] A fixing plate 50A is provided at one end of the clamping bottom frame 501, a transverse slide rail 502 is provided in the X-axis direction of the clamping bottom frame 501, and a plurality of first positioning holes 5011 are provided parallel to the transverse slide rail 502; the second transverse clamping module 504 and the third transverse clamping module 505 are connected to the slider of the transverse slide rail 502; a first adjustment positioning component 508 is provided on one side of the second transverse clamping module 504 and the third transverse clamping module 505, and the first adjustment positioning component 508 is connected to one of the first positioning holes 5011.

The relative position of the positioning threaded hole 50811 changes, and the first positioning long hole 50812 is inserted with the first positioning bolt 5084; therefore, after determining the X-axial position of the second horizontal clamping module 504 and the third horizontal clamping module 505 in the clamping bottom frame 501, the first handle 50823 can be rotated so that the first plug block 50822 is inserted into one of the first positioning holes 5011. This step is coarse adjustment. After the coarse adjustment is completed, the position of the second horizontal clamping module 504 and the first adjustment positioning component 508, or the position of the third horizontal clamping module 505 and the first adjustment positioning component 508 is adjusted. This step is fine adjustment. After the fine adjustment is completed, the first positioning bolt 5084 is passed through the first positioning long hole 50812 and finally tightened with the threaded holes on the second horizontal clamping module 504 and the third horizontal clamping module 505. At this time, the X-axial position of the second horizontal clamping module 504 and the third horizontal clamping module 505 in the clamping bottom frame 501 is determined.

[0023] The hollow holes include a first hollow hole 5012 and a second hollow hole 50513, and the hollow slots include a first hollow long slot 5013 and a second hollow long slot 50512; the first hollow hole 5012 and the first hollow long slot 5013 are both located on the fixing plate 50A; the second hollow hole 50513 and the second hollow long slot 50512 are both located on the third horizontal clamping module 505; first slide rails 503 are provided on both sides of the first hollow long slot 5013 1, a plurality of second positioning holes 5014 are arranged on the fixed plate 50A parallel to the first slide rail 5031; the first pneumatic clamping platform 506 includes a first bottom plate 5061, and a center hole 50611 is arranged at the center of the first bottom plate 5061, so that the first pneumatic clamping platform 506 fixed to the fixed plate 50A and the first pneumatic clamping platform 506 fixed to the second movable plate 5051, the hollow holes are exactly opposite to the center hole 50611, and the hollow holes are ... A first pneumatic clamping table 506 that moves relatively to each other and a first pneumatic clamping table 506 that moves relatively to the second movable plate 5051, the middle hole 50611 is exactly opposite to the hollow slot, so for door frames of different sizes, no matter whether the clamping assembly 5 is facing the welding robot 2 from the front or the back, the docking positions of the four corners of the door frame can be exposed, so the welding robot 2 can weld the outer periphery of the docking positions of the four corners of the door frame, thus avoiding the operator from removing the door frame after welding one side of the door frame and then installing it on the other side, the secondary clamping will not only deform the door frame that is not very firm in welding, but also cause clamping misalignment, which will affect the final welding effect of the door frame, in addition, the time for secondary clamping of the door frame is reduced, which can not only improve production efficiency, but also reduce the risk of operation for operators, thereby ensuring safe and orderly production.

[0024] One of the two first pneumatic clamping tables 506 on the first transverse clamping module 503 is connected to the slider of the first slide rail 5031, and the first pneumatic clamping table 506 is also connected to the second adjustment and positioning component 509, and the second adjustment and positioning component 509 is connected to one of the second positioning holes 5014; third slide rails 5052 are arranged on both sides of the second hollow long groove 50512, and fourth positioning holes 50511 are arranged on the third transverse clamping module 505 parallel to the third slide rail 5052; one of the two first pneumatic clamping tables 506 on the second movable plate 5051 is connected to the slider of the third slide rail 5052, The first pneumatic clamping table 506 is also connected to a second adjusting positioning component 509, which is connected to one of the fourth positioning holes 50511; a plurality of third positioning holes 50411 are provided on the first movable plate 5041, and second slide rails 5042 are provided on both sides of the third positioning holes 50411; one of the two second pneumatic clamping tables 507 on the first movable plate 5041 is connected to the slider of the second slide rail 5042, and the second pneumatic clamping table 507 is also connected to the second adjusting positioning component 509, which is connected to one of the third positioning holes 50411.

Therefore, after determining the Y-axis position of the first pneumatic clamping table 506 on the clamping base frame 501 and the second movable plate 5051, and determining the position of the second pneumatic clamping table 507 on the first movable plate 5041, the second handle 50923 can be rotated so that the second plug block 50922 is inserted into one of the second positioning holes 5014 or one of the third positioning holes 50411 or one of the fourth positioning holes 50511. This step is coarse adjustment. After the coarse adjustment is completed, the position of the second adjustment positioning component 509 on the first pneumatic clamping table 506 and the second pneumatic clamping table 507 is adjusted. This step is fine adjustment. After the fine adjustment is completed, the second positioning bolt 5094 is passed through the second positioning long hole 50912 and finally tightened with the threaded holes on the first pneumatic clamping table 506 and the second pneumatic clamping table 507. At this time, the Y-axis position of the first pneumatic clamping table 506 and the second pneumatic clamping table 507 on the clamping base frame 501 is determined.

[0026] Two pressing components 5063 are arranged around the middle hole 50611 of the first pneumatic clamping platform 506, and the two pressing components 5063 are arranged at an angle of 90 degrees; two pushing and clamping components 5062 are also arranged on the first bottom plate 5061, and the two pushing and clamping components 5062 are arranged at an angle of 90 degrees; one of the pressing components 5063 is arranged parallel to one of the pushing and clamping components 5062, and the other pressing component 5063 is arranged parallel to the other pushing and clamping component 5062; therefore, the pressing components 5063 and the pushing and clamping components 5062 on the four first pneumatic clamping platforms 506 can clamp the steel at the four corners of the door frame, ensuring that the steel does not move during electric welding.

[0027] The second bottom plate 5071 is also provided with a pushing and clamping component 5062 and a pressing component 5063, which are arranged in parallel.

When steel materials are spliced ​​to form a door frame, the concave side of the steel materials faces the outside of the door frame, so the pushing block 50621 can be inserted into the concave surface of the steel materials, so that the steel materials can be clamped stably, and the hollow part of the steel materials will not be deformed due to force during the clamping process. The first top surface 5062A, the second top surface 5062B, the third top surface 5062C, and the fourth top surface 5062D respectively support several surfaces of the concave side of the steel material, so that the several surfaces of the concave part of the steel material can be supported. The pressing component 5063 includes a positioning pressing seat 50631, and the positioning pressing seat 50631 is provided with a positioning groove 5063A; the cross section of the steel is reversely inserted into the positioning groove 5063A, which can not only position the front and rear doors of the steel, but also position the upper and lower sides of the steel, so that the operator can easily find the placement position of the steel when placing the steel on the clamping assembly 5, thereby making the production line more efficient.

[0029] The positioning and pressing seat 50631 is provided with an angle pressing cylinder 50632, which presses the top of the steel material so that the steel material is clamped by the pressing component 5063 in all directions. In this way, the steel material will not fall even if the clamping assembly 5 rotates.
