Description

Technical Field

[0001] The present invention belongs to the technical field related to welding equipment, and more specifically, particularly relates to an integrated welding processing equipment for furniture production. Background Art

[0002] Furniture support feet usually include columns for supporting sofas and connecting pieces for connecting the columns and sofas. The columns are in various shapes such as sleeve-shaped, square cross-section shape, rectangular cross-section shape, etc., and one end of the column is welded to the middle of the connecting piece. In the production of furniture support feet, usually the columns and connecting pieces are fixed separately first, and the fixed columns and connecting pieces are fitted at the welding position, and then the welding gun of a hand-held welding machine is used for welding. However, the welding equipment in the prior art has the following defects: In the prior art, when the welding processing equipment welds a column with a rectangular cross-section and a connecting piece, since the columns and connecting pieces need to be fixed separately, it is easy to have a deviation between the center of the column and the center of the connecting piece, resulting in low welding quality of the furniture support feet; and since the cross-section of the column is rectangular, the width and length of the column are different, making it difficult to quickly clamp and fix columns of different sizes, thereby affecting the quality of the furniture support feet.

[0003] In the prior art, in order to align the center of the column with the center of the connecting piece, the welding processing equipment usually uses a special fixture to rigidly press the column on the connecting piece to fix the column and the connecting piece, and then a welding machine is used to weld the column and the connecting piece together. In this method, when the two end faces of the column are uneven during production, when the special fixture fixes the column to the connecting piece, it is easy to cause the column to be skewed, thereby affecting the quality of the furniture support feet.

[0004] In the prior art, in order to improve the welding efficiency of furniture support feet, the welding processing equipment usually needs to drive the column and the connecting piece to rotate and cooperate with the welding assembly to perform welding operations on the furniture support feet; however, when driving the column and the connecting piece to rotate, there is a problem that the column and the connecting piece rotate out of sync, which easily causes damage to the welding points, thereby affecting the quality and efficiency of the furniture support feet.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an integrated welding processing equipment for furniture production is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention is an integrated welding processing equipment for furniture production. Through the arrangement of a movable block, a clamping block, a limiting groove, a first hydraulic telescopic part, and a circular plate, the fixed frame moves downward to drive the circular plate to move downward to cooperate with the movable block to be fixed. Through the upper side of the limiting groove being supported by the lower side of the circular plate in cooperation with the inclined arrangement of the first hydraulic telescopic part, the circular plate moves downward and is supported by the four first hydraulic telescopic parts in an inclined manner, so that the four clamping blocks move radially outward. The four clamping blocks move radially outward to contact the inner wall of the through hole, so that the clamping blocks and the limiting grooves are used to clamp and fix the connecting piece to prevent the connecting piece from moving up and down in the workpiece placement groove. Then, through the arrangement of the clamping plate, the disc, the second hydraulic telescopic part, the first telescopic connecting tube, and the second telescopic connecting tube, the movable block continues to move downward to cooperate with the four clamping blocks to be supported by the inner wall of the through hole, so that the four first hydraulic telescopic parts shrink. The first hydraulic telescopic part contracts so that the solution in the first hydraulic telescopic part enters the movable block through the first telescopic connecting tube, and the coolant in the movable block enters the four second hydraulic telescopic parts through the four second telescopic connecting tubes, respectively, so that the four second hydraulic telescopic parts are quickly extended, and the radial outer movement distance of the four clamps is increased, which is conducive to the rapid clamping and fixing of the inner wall of the pillar. Finally, the four clamps move radially outward, and the two relative clamps contact the opposite side walls of the pillar respectively, so that the inner wall of the pillar is initially clamped and fixed by the two relative clamps. At this time, the two relative clamps are resisted by the inside of the pillar, so that the two relative second hydraulic telescopic parts contract. The coolant in the two relative second hydraulic telescopic parts enters the movable block through the two relative second telescopic connecting tubes. The coolant in the movable block enters into the other two second hydraulic telescopic parts respectively through the other two second telescopic connecting pipes, thereby promoting the extension degree of the other two second hydraulic telescopic parts, and further increasing the radial outward movement distance of the other two clamps, so that the four clamps and the first rubber part can be used to center the four side walls of the pillar, and the center of the pillar is made to correspond to the center of the connecting plate, so as to facilitate the use of the clamping assembly to center the connecting plate and the pillar.

[0018] The present invention discloses an integrated welding processing equipment for furniture production. Through the setting of rubber pressure blocks and guide blocks, the radial outer side movement of four clamps drives the radial outer side movement of four rubber pressure blocks. The radial outer side movement of the rubber pressure blocks is guided by the inclined surfaces of two guide blocks, so that the rubber pressure blocks move downward. The four rubber pressure blocks move downward to press the upper end of the pillar downward, so that the pillar is rigidly pressed on the connecting piece, and the four clamps are used to keep the pillar in a vertical state to avoid the pillar from tilting. Through the setting of the protrusions, the rubber pressure blocks move downward to drive a number of protrusions to move downward, and the protrusions are used to abut against the upper end of the pillar to further limit the extrusion of the pillar, which is conducive to improving the extrusion contact between the lower end of the pillar and the upper side of the connecting piece, thereby improving the quality of welding of the furniture support legs. Finally, through the setting of the counterweight block, the pressure block, the U-shaped block, and the second rubber part, the rotation of the disc drives the four counterweight blocks to rotate, and the rotation of the four counterweight blocks generates centrifugal force. Under the action of the centrifugal force, the four counterweight blocks move radially outward. Through one end of the counterweight block contacting the upper inclined surface of the pressure block, the counterweight block moves radially outward to squeeze the pressure block and the U-shaped block downward, so that the pressure block and the U-shaped block move downward. The downward movement of the U-shaped block drives the two second rubber parts to move downward, and the two second rubber parts move downward to push the two guide blocks to swing downward. The two guide blocks swing downward, increasing the downward force on the rubber pressure block and the plurality of protrusions, and increasing the pressure of the rubber pressure block and the plurality of protrusions on the upper end of the pillar; and one side of the rubber pressure block is an inclined structure, and the inclined surfaces of the four rubber pressure blocks are used to perform radial outward extrusion and limiting action on the four inner walls of the upper end of the pillar, which is beneficial to promote the limiting and fixing action between the connecting piece and the pillar during the rotation of the furniture support leg. The clamping assembly can adjust the limiting clamping action of the furniture support leg according to the state of the clamping assembly.

[0019] The present invention provides an integrated welding processing equipment for furniture production. Through the setting of positioning blocks, a plurality of positioning blocks are used in a plurality of positioning holes respectively, so as to position the connecting piece, and the center of the connecting piece corresponds to the center of the workpiece support seat. Then, through the setting of the workpiece support seat, the movable block, and the positioning groove, the stepper motor is started to drive the disc to rotate, and the rotation of the disc drives the fixed frame and the movable block to rotate. The lower end of the movable block is located in the positioning groove, so that the rotation of the clamping assembly can drive the rotation of the workpiece support seat, and the rotation of the workpiece support seat and the clamping assembly drives the connecting piece and the pillar to rotate synchronously, thereby improving the quality and efficiency of welding the furniture support legs.

[0037] Preferably, referring to Appendix Figure 1 to Appendix Figure 3 , a stepping motor 22 is installed on the upper side of the movable plate 21. The output end of the stepping motor 22 is fixedly connected to the upper side of the disc 23.

[0038] Specific use of the present invention: The furniture support leg includes a connecting piece 56 and a support column 57. The connecting piece 56 is provided with a plurality of positioning holes 58 in a circumferential array. A through hole 59 is provided in the middle of the connecting piece 56. The cross section of the support column 57 is a rectangular structure.

[0039] First, the staff places the connecting piece 56 in the workpiece placement groove 16, and uses a plurality of positioning blocks 17 to position the connecting piece 56 in the plurality of positioning holes 58, and the center of the connecting piece 56 corresponds to the center of the workpiece support seat 12. The staff places the support column 57 on the upper side of the connecting piece 56. The control system controls the lifting mechanism 20 to extend and drive the movable plate 21 to move downward, and the movable plate 21 moves downward to drive the clamping assembly to move downward, so that the clamping assembly enters the furniture support foot.

[0040] Secondly, the movable plate 21 moves downward to drive the disc 23 to move downward, and the disc 23 moves downward to drive the fixed frame 24 and the movable block 25 to move downward, and the lower end of the movable block 25 slides in the positioning groove 15. The lower side of the positioning groove 15 abuts against the lower end of the movable block 25, so that the fixed frame 24 is on the outer wall of the movable block 25. The fixed frame 24 moves downward to drive the circular plate 55 to move downward to cooperate with the movable block 25 to be fixed, and the upper side of the limiting groove 27 is abutted by the lower side of the circular plate 55 to cooperate with the inclined arrangement of the first hydraulic telescopic member 34, and the circular plate 55 moves downward and is abutted by the four first hydraulic telescopic members 34, so that the four clamping blocks 26 move radially outward. The four clamping blocks 26 move radially outward to contact the inner wall of the through hole 59, so that the clamping blocks 26 and the limiting grooves 27 are used to clamp and fix the connecting piece 56, so as to prevent the connecting piece 56 from moving up and down in the workpiece placement groove 16. The upper end of the movable block 25 slides in the fixed frame 24, thereby compressing the first compression spring 33 to generate elastic force. Under the elastic force of the first compression spring 33, the clamping assembly can quickly release the furniture support leg. The clamping block 26 moves radially outward to drive the first T-shaped slider 38 to slide in the first slide groove 39. The sliding of the first T-shaped slider 38 compresses the first spring 40 to generate elastic force. Under the elastic force of the first spring 40, the clamping block 26 can be moved and reset.

[0041] At the same time, the disc 23 and the fixed frame 24 move downwards and cooperate with the lower end of the movable block 25 to be supported by the positioning groove 15, so that the fixed frame 24 slides on the outer wall of the movable block 25. The four clamping plates 28 move downwards due to the downward movement of the disc 23 and cooperate with the four second hydraulic expansion members 36 to be arranged obliquely, so that the four clamping plates 28 move radially outwards.

[0042] Then, the movable block 25 continues to move downward to cooperate with the four clamping blocks 26 to be supported by the inner wall of the through hole 59, so that the four first hydraulic telescopic parts 34 are contracted. The contraction of the first hydraulic telescopic part 34 causes the solution in the first hydraulic telescopic part 34 to enter the movable block 25 through the first telescopic connecting tube 35, and the coolant in the movable block 25 enters the four second hydraulic telescopic parts 36 through the four second telescopic connecting tubes 37, respectively, so that the four second hydraulic telescopic parts 36 are quickly extended, increasing the radial outer movement distance of the four clamping plates 28. The radial outer sides of the four clamping plates 28 drive the radial outer sides of the four first rubber parts 61, which is conducive to quickly clamping and fixing the inner wall of the pillar 57. Among them, the radial outer movement of the clamping plate 28 drives the second T-shaped slider 41 to slide in the second slide groove 42, and the sliding of the second T-shaped slider 41 compresses the second spring 43 to generate elastic force, and the clamping plate 28 can be moved and reset under the action of the elastic force of the second spring 43.

[0043] At the same time, since the cross section of the pillar 57 is a rectangular structure, the distance between the two opposite side walls of the pillar 57 is smaller than the distance between the other two opposite side walls of the pillar 57. The four clamping plates 28 move radially outward, wherein the two opposite clamping plates 28 contact the two opposite side walls of the pillar 57 respectively, so that the inner wall of the pillar 57 is initially clamped and fixed by the two opposite clamping plates 28. At this time, the two opposite clamping plates 28 are resisted by the inside of the pillar 57, so that the two opposite second hydraulic telescopic parts 36 are contracted. The coolant in the two opposite second hydraulic telescopic parts 36 enters the movable block 25 through the two opposite second telescopic connecting pipes 37. The coolant in the movable block 25 enters into the other two second hydraulic telescopic parts 36 respectively through the other two second telescopic connecting tubes 37, thereby promoting the extension degree of the other two second hydraulic telescopic parts 36, and further increasing the radial outward movement distance of the other two clamping plates 28. Therefore, the four clamping plates 28 and the first rubber member 61 can be used to center the four side walls of the pillar 57, and the center of the pillar 57 is made to correspond to the center of the connecting plate 56, so as to use the clamping assembly to center the connecting plate 56 and the pillar 57.

[0044] Then, the four clamping plates 28 move radially outward, driving the four rubber pressing blocks 30 to move radially outward. The radially outward movement of the rubber pressing blocks 30 is guided by the inclined surfaces of the two guide blocks 31, so that the rubber pressing blocks 30 move downward. The four rubber pressing blocks 30 move downward to press the upper end of the pillar 57 downward, so that the pillar 57 is rigidly pressed on the connecting piece 56, and the four clamping plates 28 are used to keep the pillar 57 in a vertical state to prevent the pillar 57 from tilting. The downward movement of the rubber pressing blocks 30 drives the third T-shaped slider 44 to move downward in the third slide groove 45, so that the rubber pressing blocks 30 move downward smoothly. The downward movement of the third T-shaped slider 44 compresses the third spring 46 to generate elastic force.

[0045] At the same time, the rubber pressure block 30 moves downward, driving the plurality of protrusions 32 to move downward, and utilizing the protrusions 32 to abut against the upper ends of the pillars 57, further performing a limiting extrusion effect on the pillars 57, which is beneficial to improving the extrusion contact between the lower ends of the pillars 57 and the upper sides of the connecting pieces 56, thereby improving the quality of welding on the furniture support legs.

[0046] Finally, when the clamping assembly positions, clamps and fixes the connecting piece 56 and the pillar 57, the control system controls the stepper motor 22 to start, and the stepper motor 22 starts to drive the disc 23 to rotate, and the rotation of the disc 23 drives the fixed frame 24 and the movable block 25 to rotate. The lower end of the movable block 25 is located in the positioning groove 15, so that the rotation of the clamping assembly can drive the workpiece support seat 12 to rotate, and the rotation of the workpiece support seat 12 and the clamping assembly drives the connecting piece 56 and the pillar 57 to rotate synchronously, thereby improving the quality and efficiency of the welding of the furniture support legs. The control system controls the operation of the welding machine 13, and the connecting piece 56 and the pillar 57 rotate synchronously, and cooperates with the welding machine 13 to perform welding work between the connecting piece 56 and the pillar 57.

[0047] At the same time, the rotation of the disc 23 drives the four counterweights 50 to rotate, and the rotation of the four counterweights 50 generates centrifugal force, and under the action of the centrifugal force, the four counterweights 50 move radially outward. One end of the counterweight 50 contacts the upper inclined surface of the pressure block 53, and the counterweight 50 moves radially outward to press the pressure block 53 and the U-shaped block 52 downward, so that the pressure block 53 and the U-shaped block 52 move downward. The downward movement of the U-shaped block 52 drives the two second rubber pieces 54 to move downward, and the two second rubber pieces 54 move downward to push the two guide blocks 31 to swing downward. The two guide blocks 31 swing downward, increasing the downward force on the rubber pressure block 30 and the plurality of protrusions 32, and increasing the pressure of the rubber pressure block 30 and the plurality of protrusions 32 on the upper end of the pillar 57; and one side of the rubber pressure block 30 is an inclined structure, and the inclined surfaces of the four rubber pressure blocks 30 are used to perform radial outward extrusion and limiting on the four inner walls of the upper end of the pillar 57, which is beneficial to promote the limiting and fixing effect between the connecting piece 56 and the pillar 57 during the rotation of the furniture support foot. The clamping assembly can be adjusted according to the state to limit the clamping effect of the furniture support leg. The counterweight block 50 moves radially outward to stretch the tension spring 51 to generate elastic force, and the U-shaped block 52 moves downward to compress the second compression spring 60 to generate elastic force.

[0048] The integrated welding processing equipment for furniture production of the present invention, through the arrangement of the movable block 25, the clamping block 26, the limiting groove 27, the first hydraulic telescopic member 34, and the circular plate 55, the fixed frame 24 moves downward to drive the circular plate 55 to move downward to cooperate with the movable block 25 to be fixed, and the upper side of the limiting groove 27 is supported by the lower side of the circular plate 55 to cooperate with the inclined arrangement of the first hydraulic telescopic member 34, and the circular plate 55 moves downward and is supported by the four first hydraulic telescopic members 34 to make the four clamping blocks 26 move radially outward. The four clamping blocks 26 move radially outward to contact the inner wall of the through hole 59, so that the clamping block 26 and the limiting groove 27 are used to clamp and fix the connecting piece 56, so as to prevent the connecting piece 56 from moving up and down in the workpiece placement groove 16. Then, through the arrangement of the clamping plate 28, the disc 23, the second hydraulic telescopic member 36, the first telescopic connecting tube 35, and the second telescopic connecting tube 37, the movable block 25 continues to move downward to cooperate with the four clamping blocks 26 to be resisted by the inner wall of the through hole 59, so that the four first hydraulic telescopic members 34 are contracted. The contraction of the first hydraulic telescopic member 34 causes the solution in the first hydraulic telescopic member 34 to enter the movable block 25 through the first telescopic connecting tube 35, and the coolant in the movable block 25 enters the four second hydraulic telescopic members 36 through the four second telescopic connecting tubes 37, so that the four second hydraulic telescopic members 36 are quickly extended, increasing the radial outer movement distance of the four clamping plates 28, which is conducive to the rapid clamping and fixing of the inner wall of the pillar 57. Finally, the four clamping plates 28 move radially outward, wherein the two relative clamping plates 28 are respectively in contact with the opposite side walls of the pillar 57, so that the inner wall of the pillar 57 is initially clamped and fixed by the two relative clamping plates 28. At this time, the two relative clamping plates 28 are resisted by the inside of the pillar 57, so that the two relative second hydraulic telescopic members 36 are contracted. The coolant in the two second hydraulic telescopic parts 36 enters the movable block 25 through the two second telescopic connecting tubes 37. The coolant in the movable block 25 enters the other two second hydraulic telescopic parts 36 through the other two second telescopic connecting tubes 37, thereby promoting the extension of the other two second hydraulic telescopic parts 36, further increasing the radial outer movement distance of the other two clamping plates 28, so that the four clamping plates 28 can be used to center the four side walls of the pillar 57, and the center of the pillar 57 corresponds to the center of the connecting piece 56, so as to use the clamping assembly to center the connecting piece 56 and the pillar 57.

[0049] The integrated welding processing equipment for furniture production of the present invention, through the setting of rubber pressing blocks 30 and guide blocks 31, the radial outward movement of four clamping plates 28 drives the radial outward movement of four rubber pressing blocks 30, and the radial outward movement of the rubber pressing blocks 30 is guided by the inclined surfaces of the two guide blocks 31, so that the rubber pressing blocks 30 move downward. The four rubber pressing blocks 30 move downward to press the upper end of the pillar 57 downward, so as to press the pillar 57 rigidly on the connecting piece 56, and the four clamping plates 28 are used to keep the pillar 57 in a vertical state to avoid the pillar 57 from tilting. Then, through the setting of the protrusions 32, the rubber pressing blocks 30 move downward to drive a number of protrusions 32 to move downward, and the protrusions 32 are used to press against the upper end of the pillar 57, and the pillar 57 is further limited and squeezed, which is conducive to improving the squeezing contact between the lower end of the pillar 57 and the upper side of the connecting piece 56, thereby improving the quality of welding of the furniture support legs. Finally, through the arrangement of the counterweight block 50, the pressure block 53, the U-shaped block 52, and the second rubber member 54, the rotation of the disc 23 drives the four counterweight blocks 50 to rotate, and the rotation of the four counterweight blocks 50 generates centrifugal force, under the action of the centrifugal force, the four counterweight blocks 50 move radially outward. As one end of the counterweight block 50 contacts the upper inclined surface of the pressure block 53, the counterweight block 50 moves radially outward to press the pressure block 53 and the U-shaped block 52 downward, so that the pressure block 53 and the U-shaped block 52 move downward. The U-shaped block 52 moves downward, driving the two second rubber pieces 54 to move downward. The two second rubber pieces 54 move downward, pushing the two guide blocks 31 to swing downward. The two guide blocks 31 swing downward, increasing the downward force on the rubber pressing block 30 and the plurality of protrusions 32, and increasing the pressure of the rubber pressing block 30 and the plurality of protrusions 32 on the upper end of the pillar 57; and one side of the rubber pressing block 30 is an inclined structure, and the inclined surfaces of the four rubber pressing blocks 30 are used to perform radially outward extrusion and limiting on the four inner walls of the upper end of the pillar 57, which is beneficial to promote the limiting and fixing effect between the connecting piece 56 and the pillar 57 during the rotation of the furniture support leg. The clamping assembly can adjust the limiting clamping effect on the furniture support leg according to the state.

[0050] The integrated welding processing equipment for furniture production of the present invention, through the setting of the positioning block 17, uses a plurality of positioning blocks 17 to respectively position the connecting piece 56 in a plurality of positioning holes 58, and the center of the connecting piece 56 corresponds to the center of the workpiece support seat 12. Then, through the setting of the workpiece support seat 12, the movable block 25, and the positioning groove 15, the stepper motor 22 is started to drive the disc 23 to rotate, and the rotation of the disc 23 drives the fixed frame 24 and the movable block 25 to rotate. The lower end of the movable block 25 is located in the positioning groove 15, so that the rotation of the clamping assembly can drive the rotation of the workpiece support seat 12, and the rotation of the workpiece support seat 12 and the clamping assembly drives the connecting piece 56 and the support 57 to rotate synchronously, thereby improving the quality and efficiency of welding the furniture support legs.
