Description

Technical Field

[0001] This invention relates to the field of welding equipment, and in particular to a furniture metal frame processing equipment with welding function. Background Technology

[0002] In the furniture manufacturing industry, metal frames (such as I-beam frames) are widely used due to their stable structure. These frames are typically welded together from components such as bottom crossbeams, vertical beams, and top crossbeams. Traditional production methods rely on manual welding, which suffers from drawbacks such as low efficiency, inconsistent quality, and high labor intensity. With the development of automation technology, welding robots have gradually been introduced into this type of production process.

[0003] However, in the existing technology, there are still significant shortcomings in directly using general-purpose welding robots for welding such specific components. When welding assembled "I"-shaped metal brackets, due to their complex structure, the weld seams are distributed on multiple sides of the workpiece; conventional welding robots are usually fixed on one side of the workstation and can often only complete the welding operation on one side of the workpiece; for workpieces that require welding on multiple sides, manual workpiece flipping or additional robots must be configured.

Detailed Implementation

[0016] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0017] like Figures 1 to 6 As shown, the present invention provides a furniture metal bracket processing equipment with welding function, mainly used for welding furniture metal brackets 100 in the shape of an "I". The furniture metal bracket 100 includes a bottom crossbeam 101, a vertical beam 102 and a top crossbeam 103; the processing equipment mainly includes a welding robot 2, a welding fixture assembly for fixing the bracket and a controller for controlling the movement of each component. The welding robot 2 is set on one side of the welding fixture assembly, and welding is performed using the welding robot.

[0018] To facilitate the support and fixation of the furniture metal frame 100, a support platform 1 supported by multiple pillars 13 and a rotating worktable 3 are provided; the welding fixture assembly includes a first clamping mechanism and a second clamping mechanism respectively installed on the support platform 1 and the rotating worktable 3.

[0019] Among them, such as Figure 2-5 The first clamping mechanism includes a first clamp 2a fixed on a support platform 1. A side frame 11 is fixed on one side of the support platform 1. Two clamping modules 11a for clamping the vertical beam 102 are fixed on the side frame 11. A top plate 12 is fixed on the top of the side frame 11. A clamping cylinder 121 is fixed on the bottom side of the top plate 12. The movable end of the clamping cylinder 121 is connected to the upper surface of a first upper pressure plate 123. Both ends of the first upper pressure plate 123 are connected to extension plates 14. The ends of the extension plates 14 are bent to form end plates 140. The inner wall of the end plate 140 abuts against the end face of the top crossbeam 103. The bottom end of the end plate 140 is provided with a slot 143. A limiting plate 141 is provided on one side of the end plate 140. The inner wall of the limiting plate 141 abuts against the end side of the top crossbeam 103. A guide telescopic sleeve rod 122 is connected between the upper pressure plate 123 and the top plate 12. The clamping module 11a includes a telescopic cylinder 111 fixed to the inner wall of the side frame 11. A U-shaped plate 112 is connected to the end of the telescopic cylinder 111. Both inner walls of the U-shaped plate 112 are connected to clamping plates 113 through clamping cylinders. A guide part 114 is provided at the end of the clamping plate 113. The telescopic cylinder 111 drives the U-shaped plate 112 to approach the vertical beam 102. Then, the clamping plates 113 on both sides clamp the vertical beam 102, which can effectively fix the vertical beam 102 and prevent it from shifting during welding, ensuring the accuracy of the weld position. At the same time, the end plate 140 and the limiting plate 141 restrict the front-back and lateral positions of the top crossbeam 103, ensuring the accuracy of the position of the top crossbeam 103.

[0020] Among them, such as Figure 2-5 A base 130 is fixed on the worktable surface of the rotary worktable 3. A second clamp 2b is fixed on the upper surface of the base 130. A pair of columns 31 are fixed on the upper surface of one end of the base 130. The two columns 31 are connected to a mounting beam 32 with one end suspended. A clamping cylinder 33 is installed on the bottom side of the mounting beam 32. The movable end of the clamping cylinder 33 is connected to the upper surface of the second upper pressure plate 34. A guide telescopic sleeve 35 is connected between the second upper pressure plate 34 and the mounting beam 32. A rectangular groove 341 is opened on the lower surface of the second upper pressure plate 34 along its length direction. The top crossbeam 103 is accommodated in the rectangular groove 341. The second upper pressure plate 34 and the second clamp 2b are combined to form a first clamping mechanism.

[0021] To achieve the welding of the furniture metal frame 100, the specific steps include: Place the bottom crossbeam 101 onto the first clamp 2a, and control the action of the first clamp 2a to clamp the bottom crossbeam 101; The vertical beam 102 is inserted into the two clamping modules 11a, and the bottom end of the vertical beam 102 is controlled to abut against the upper surface of the bottom crossbeam 101. The clamping modules 11a are controlled to clamp the vertical beam 102. Next, place the top crossbeam 103 on top of the crossbeam 101, and control the extension of the clamping cylinder 121 to drive the first upper pressure plate 123 to move downward. At this time, the initial fixation of the furniture metal bracket 100 is completed. Control the welding robot 2 to perform preliminary welding on the fillet weld between the bottom crossbeam 101 and the vertical beam 102, and the fillet weld between the top crossbeam 103 and the vertical beam 102. The telescopic cylinder 111 of the control clamping module 11a retracts, and then the first clamp 2a is controlled to release the clamping effect on the bottom crossbeam 101. The pressing cylinder 121 is controlled to retract, which drives the first upper pressure plate 123 to move upward until the first upper pressure plate 123 is disengaged from the top crossbeam 103. At this time, the top crossbeam 103 is accommodated in the slot 143. Under the limiting effect of the slot 143, the top crossbeam 103 is prevented from tipping over. The rotating worktable 3 is controlled to rotate so that the first clamp 2a and the second clamp 2b are concentric. The furniture metal bracket 100, which has completed the initial welding, is controlled to move from the first clamp 2a to the second clamp 2b. During the movement, the bottom crossbeam 101 is limited by the action of the first clamp 2a and the second clamp 2b, and the top crossbeam 103 is limited by the action of the slot 143 and the rectangular slot 341. Once the furniture metal bracket 100 has completely moved onto the second clamp 2b, control the extension of the clamping cylinder 33 to drive the second upper pressure plate 34 to move downwards and abut against the top crossbeam 103; drive the rotating worktable 3 to rotate 180°, at which point control the unwelded side of the furniture metal bracket 100 to face the welding robot 2, control the welding robot 2 to perform secondary welding on the fillet welds of the bottom crossbeam 101 and the vertical beam 102 on the current side, and the fillet welds of the top crossbeam 103 and the vertical beam 102; After the secondary welding of the furniture metal bracket 100 is completed and the material is unloaded, the rotating worktable 3 is rotated 180° again to return to the initial state and is ready to be used.

[0022] like Figure 7-10To facilitate the clamping of the bottom crossbeam 101 using the first clamp 2a and the second clamp 2b, and to facilitate the control of the movement of the bottom crossbeam 101 within the first clamp 2a and the second clamp 2b, the first clamp 2a and the second clamp 2b provided by the present invention have the same structure, both including a base plate 21. Symmetrically arranged bosses 22 and 23 are mounted on the upper surface of the base plate 21, and the bosses 22 and 23 form channels for clamping the bottom crossbeam 101. Several grooves 221 are formed along the length of the inner wall of the boss 22. The bottom side of the groove 221 is connected by a spring 222 to a movable column 223 that slides along the inner wall of the groove 221. A ball bearing 224 is embedded in the end face of the movable column 223. The outer wall of the boss 23 is connected to a mounting plate 25, which has at least two oblong holes 251. The length direction of the oblong holes 251 is perpendicular to the length direction of the boss 23. A bolt 20 is threaded onto the base plate 21, passing through the oblong holes 251. At least two grooves 233 are formed on the inner wall of the boss 23. The bottom side of the grooves 233 is connected by a spring 222. The second telescopic cylinder 234 is connected to the movable plate 24. The movable plate 24 has several through holes 241 along its length. The inner wall of the second boss 23 is provided with several protruding posts 231 that mate with the through holes 241 one by one. The end face of the protruding post 231 is embedded with the second ball bearing 232. The spring-supported movable post 223 and the movable plate 24 driven by the second telescopic cylinder 234 form a composite clamping of elasticity and rigidity for the bottom crossbeam 101. The arrangement of the first ball bearing 224 and the second ball bearing 232 facilitates the control of the telescopic cylinder 234 to retract and drive the movable plate 24 away from the bottom crossbeam. When one side of 101 moves, ball bearing 232 protrudes from the clamping surface of the movable plate 24. At this time, under the action of the spring, ball bearing 224 protrudes from the inner wall surface of the boss 22. Then, ball bearing 232 and ball bearing 224 respectively abut against the two sides of the bottom crossbeam 101. Thus, when controlling the movement of the bottom crossbeam 101 in the channel, the friction is reduced by the arrangement of ball bearing 224 and ball bearing 232. By adjusting the position of the boss 23 through the waist-shaped hole 251, it can adapt to the bottom crossbeam 101 of different widths, thus enhancing the versatility of the equipment.

[0023] During operation, the telescopic cylinder 234 extends, driving the movable plate 24 to move towards the bottom crossbeam 101. Together with the boss 22, it firmly clamps the bottom crossbeam 101 from both sides, which is a rigid clamping state, ensuring the stability of the workpiece during welding.

[0024] Based on the above, in order to facilitate the movement of the furniture metal bracket 100 from the first clamp 2a to the second clamp 2b after the initial welding is completed, as follows: Figure 11In this invention, a rectangular channel is formed along the length of the mounting plate 25; a support beam 212 is fixed to the bottom side of the base plate 21 by an L-shaped or U-shaped bracket 211; a guide rail 213 is fixed to the upper surface of the support beam 212; an electric slide block 214 that slides along the length of the guide rail 213 is provided on the guide rail 213; a telescopic push rod 215 is horizontally mounted on the electric slide block 214; the end of the telescopic push rod 215 is connected to a push plate 216 that passes through the rectangular channel; a guide rod 217 is connected to one side of the push plate 216; and the electric slide block 214... An insertion hole for inserting the guide rod 217 is provided; the bottom side of the base plate 21 is fixed to the upper surface of the support platform 1 by the support column 26; based on the setting of the push plate 216, it is convenient to use the push plate 216 to press against the end face of the bottom crossbeam 101 to limit the position of the bottom crossbeam 101 during use; after the initial welding is completed, the electric slide 214 can drive the push plate 216 to smoothly push the workpiece out of the fixture channel, thereby assisting in moving the furniture metal bracket 100 from the first fixture 2a into the second fixture 2b.

[0025] Simultaneously, after the furniture metal bracket 100 is moved from the first clamp 2a into the second clamp 2b, the push plate 216 of the second clamp 2b is used to press against the end face of the bottom crossbeam 101 to limit the position of the bottom crossbeam 10, thereby completing the positioning of the entire furniture metal bracket 100; after the secondary welding is completed in the second clamp 2b, the push plate 216 in the second clamp 2b is used to smoothly push the workpiece out of the clamp channel, thereby assisting in unloading the furniture metal bracket 100 from the second clamp 2b.

[0026] In other specific embodiments, such as Figure 2-3 When the furniture metal support 100 also includes diagonal bracing, two sets of diagonal bracing are provided between the bottom crossbeam 101 and the top crossbeam 103, located on both sides of the vertical beam 102. The diagonal bracing includes diagonal bracing one 105 and diagonal bracing two 104. The top of diagonal bracing one 105 is welded to the bottom side of the top crossbeam 103, and the bottom of diagonal bracing two 104 is welded to the upper surface of the bottom crossbeam 101. The top of diagonal bracing two 104 is welded to one side of the vertical beam 102, and the bottom of diagonal bracing one 105 is welded to the side wall of diagonal bracing two 104.

[0027] During the processing of the metal frame 100 of this furniture, in order to facilitate the fixing of the first diagonal brace 105 and the second diagonal brace 104 during the welding process, two clamping parts 16a are installed above the side frame 11 to fix the first diagonal brace 105, and two clamping parts 16b are installed below the side frame 11 to fix the second diagonal brace 104; the two clamping parts 16a are located on both sides of the vertical beam 102, and the two clamping parts 16b are located on both sides of the vertical beam 102; the clamping parts 16a and the clamping parts 16b have the same structure, including a movable through-type side frame 11. The movable rod 15 has its end connected to the connecting sleeve 163, which is provided with locking bolts 164 on its periphery. The connecting sleeve 163 is fixed to one side of a mounting base 160. A telescopic cylinder 161 is fixed to one side of the mounting base 160. The movable end of the telescopic cylinder 161 is connected to an L-shaped positioning clamp 162. A telescopic cylinder 18 is installed on the back of the side frame 11. The movable end of the telescopic cylinder 18 is connected to a movable frame 17. The end of the movable rod 15 is connected to the movable frame 17. The side frame 11 is provided with a through hole 110 for the movable rod 15 to pass through.

[0028] First, control the retraction cylinder 18 to retract, and control the clamping parts 16a and 16b to move towards the side closer to the furniture metal support 100; during use, manually place the diagonal rod 104 on the upper surface of the bottom crossbeam 101, with the diagonal rod 104 abutting against one inner wall of the L-shaped positioning clamp 162, and control the retraction cylinder 161 of the clamping part 16b to move. At this time, control the other inner wall of the L-shaped positioning clamp 162 to abut against the diagonal rod 104, and at this time, the two adjacent inner walls of the L-shaped positioning clamp 162 abut against the adjacent side walls of the diagonal rod 104 respectively. Then, the first diagonal rod 105 is placed between the top crossbeam 103 and the second diagonal rod 104. The first diagonal rod 105 abuts against one inner wall surface of the L-shaped positioning clamp 162. The telescopic cylinder 161 of the clamping component 16a is controlled to move. At this time, the other inner wall surface of the L-shaped positioning clamp 162 is controlled to abut against the first diagonal rod 105. At this time, the two adjacent inner wall surfaces of the L-shaped positioning clamp 162 abut against the adjacent two side walls of the first diagonal rod 105 respectively. The clamping components 16a and 16b are used to clamp and fix the first diagonal rod 105 and the second diagonal rod 104 respectively.

[0029] After welding is completed, first control the extension cylinder 18 to extend. At this time, clamping parts 16a and 16b move away from the furniture metal bracket 100 to avoid the presence of clamping parts 16a and 16b interfering with the process of the furniture metal bracket 100 moving from the first clamp 2a to the second clamp 2b.

[0030] Since the tilt angles of the first diagonal bar 105 and the second diagonal bar 104 are different in different furniture metal brackets 100, in order to ensure that the inner wall surface of the L-shaped positioning clamp 162 abuts against the first diagonal bar 105 and the second diagonal bar 104, it is necessary to control the axial direction of the telescopic cylinder 3 161 to be perpendicular to the first diagonal bar 105 and the second diagonal bar 104. Therefore, by setting the locking bolt 164 and the connecting sleeve 163, the orientation of the mounting base 160 can be adjusted during use, thereby adjusting the axial direction of the telescopic cylinder 3 161 to ensure that the inner wall surface of the L-shaped positioning clamp 162 can accurately abut against the corresponding first diagonal bar 105 and the second diagonal bar 104.

[0031] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
