A welding fixture for question-answering robot production

Abstract

The present invention belongs to the technical field of welding fixtures, and specifically is a welding fixture for question-answering robot production, including a guide component, and clamping components are symmetrically arranged on the left and right sides of the guide component, and the clamping component includes a lifting base, and a clamping sleeve is fixedly connected to the top of the lifting base. When the device uses the clamping sleeves on both sides to clamp the welding workpiece, it only needs to continuously pressurize the inner cavity of the sandwich shell through a pressure pump to ensure that the internal pressure of the sandwich shell is stable, so that the effect of the clamping soft plate stably clamping the side of the workpiece can be achieved. Since each clamping soft plate is divided into four areas, the blocks in the area where it is located can be relatively bent. Therefore, after uniform pressurization, the clamping soft plate can be uniformly fitted to the irregular outer surface of the workpiece under the pressing action of the sliding sleeve, so as to achieve a relatively tight clamping work and avoid the problem of the workpiece not being clamped tightly and slipping.

Description

Technical Field

[0001] The invention belongs to the technical field of welding fixtures, in particular to a welding fixture for producing a question-answering robot. Background Art

[0002] A fixture refers to a device used to fix the object to be processed during the mechanical manufacturing process so that it occupies the correct position for construction or inspection. In a broad sense, any device used by a fixture to quickly, conveniently and safely install the workpiece in any process can be called a fixture. In the process of robot production, the process is more complicated and often requires the assistance of a clamping mechanism.

[0003] A welding fixture for robot production with application number CN202111140090.0 uses a clamping rod to push the clamping component to move inward so that the clamping plate on the clamping component firmly fixes the workpiece to achieve clamping work. However, this clamping method can only clamp workpieces with flat contact surfaces. When clamping workpieces with arc surfaces and curved surfaces, the flat clamping plate cannot effectively clamp the workpiece, which makes the workpiece prone to slipping. If the workpiece is tightened by increasing the clamping force violently, it is very likely that the workpiece will be damaged under the strong squeezing action, so improvement is needed. Summary of the invention

The outer surface of the clamping soft plate is symmetrically provided with cross folding grooves on both sides, and each clamping soft plate is divided into four areas by the cross folding grooves, such as Figure 5As shown, through the cross folding groove, the clamping soft plate in each area can bend and deform slightly relative to each other, the outer surface of the sliding sleeve is slidably connected to the inner cavity of the sandwich cylinder shell through the socket, the outer surface of the wall-attached fixing plate is fixedly connected to the inner cavity of the sandwich cylinder shell, the outer surface of the fixed through pipe is fixedly connected to the inner cavity of the wall-attached fixing plate, the wall-attached fixing plate is attached to the inner wall of the sandwich cylinder shell, and has a certain distance from the outer wall of the sandwich cylinder shell, so as to ensure that the air pressure can enter the sliding sleeve through the fixed through pipe.

[0007] Further, the guide component includes a base sliding shell, the left and right sides of the inner wall of the base sliding shell are symmetrically provided with a dust collecting bottom machine, the middle part of the base sliding shell is provided with an auxiliary support, the front and rear sides of the outer surface of the base sliding shell are symmetrically provided with a thrust sleeve, the left and right sides of the inner wall of the thrust sleeve are symmetrically provided with a connecting slide plate, the top of the connecting slide plate is fixedly connected with a torque sleeve, the inner wall of the torque sleeve is rotatably connected with a pressure pump, and the torque sleeve can drive the sandwich shell on the connected side to rotate by twisting the pressure pump. The outer surface of the pressure pump is fixedly connected to the inner wall of the adapter sleeve, the number of the connecting slide plates is four, the outer surface of the thrust sleeve is fixedly connected to the outer surface of the base sliding shell, and the outer surface of the connecting slide plate is slidably connected to the inner wall of the thrust sleeve.

[0008] Furthermore, the lifting base includes a built-in slide cylinder, the upper surface of which is evenly provided with embedded ball bearings through a rotating groove, the inner wall of the built-in slide cylinder is slidably connected with a vertical slide rod, the top of the vertical slide rod is provided with a docking sleeve, and the lower part of the outer surface of the vertical slide rod is symmetrically provided with a concave rotating wheel. When the concave rotating wheel rotates, the vertical slide rod can be driven by friction to slide up and down relatively along the built-in slide cylinder, and independent motors are symmetrically provided on the front and rear sides of the outer surface of the concave rotating wheel, and the outer surface of the independent motor is fixedly connected with a centralized connecting plate, and the bottom end of the vertical slide rod is embedded with ball bearings to ensure that less wear is generated when it contacts the bottom of the inner wall of the base slide shell.

[0009] Furthermore, the top of the concentrated connecting plate is fixedly connected to the lower surface of the built-in slide cylinder, the upper surface of the built-in slide cylinder is slidingly connected to the top of the inner wall of the base slide shell through an embedded ball bearing, the axis of the outer surface of the built-in slide cylinder is slidingly connected to the axis of the inner wall of the base slide shell through a guide groove, the outer surface of the concave rotating wheel is rollingly connected to the outer surface of the vertical slide rod, and the top of the vertical slide rod is slidingly connected to the inner wall of the side circular rail through a docking sleeve.

The extended support plates on both sides can be extended and slid along the slide groove of the center support plate, thereby expanding the actual lifting area of ​​the center support plate.

[0011] Further, the side thrust component comprises a compression push cylinder, the right end of which is fixedly connected to a fixed disk shell, the inner wall of which is fixedly connected to a pressure washer, the side of which is evenly provided with spring compression rods, and the axis of the inner cavity of which is fixedly connected to a connecting wire.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When the device uses the clamping sleeves on both sides to clamp the welding workpiece, it only needs to continuously pressurize the inner cavity of the sandwich shell through the pressure pump to ensure that the internal pressure of the sandwich shell is stable, so that the clamping soft plate can stably clamp the side of the workpiece. Since each clamping soft plate is divided into four areas, the blocks in the area can be relatively bent. Therefore, after uniform pressurization, the clamping soft plate can be uniformly fitted to the irregular outer surface of the workpiece under the pressing action of the sliding sleeve, achieving a tighter clamping work and avoiding the problem of slipping due to loose clamping of the workpiece.

[0014] 2. When using the modified clamping plate to clamp the outer surface of the workpiece, since the pressure inside the sandwich shell can be evenly distributed to all the sliding sleeves through the fixed through pipe, the independent blocks of each clamping soft plate have the same clamping force on the outer surface of the workpiece, thereby ensuring that the clamping part of the workpiece is evenly stressed. Because the pressure pump can control the pressure, under a certain pressure, the clamping force of the modified clamping plate on the outer surface of the workpiece will not be too large, thereby avoiding the problem of damage to the workpiece under strong squeezing.

[0015] 3. After the clamping sleeve fixes the workpiece, it can slide straight along the base sliding shell under the control of the thrust sleeve. The actual height of the clamping sleeves on both sides can also be adjusted through the lifting base at the bottom, so that the clamped workpieces on both sides maintain a certain misalignment angle to meet the welding work at different points. During the clamping process, the clamping sleeve can rotate freely to adjust the welding angle of the clamped part to avoid welding dead angles.

[0016] 4. After the pressure pump starts working, the compression push cylinder located at the axis of the inner wall of the sandwich shell will expand under the action of pressure, and its spring compression rod will also be squeezed against the side of the workpiece, thereby squeezing the spring compression rod toward the side of the pressure washer. At this time, the spring compression rod is pressed for a distance. When the clamped workpiece and the clamping sleeve become loose, the spring compression rod pressed at a certain point will also reduce the pressing force on the pressure washer due to the looseness, thereby timely detecting the problem of loosening of the clamped workpiece that is difficult to observe with the naked eye.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a welding fixture for question-answering robot production, comprising a guide component 1, a clamping component 3 is symmetrically arranged on the left and right sides of the guide component 1, the clamping component 3 comprises a lifting base 31, a clamping sleeve 32 is fixedly connected to the top of the lifting base 31, and a side thrust component 33 is arranged at the axis center of the inner wall of the clamping sleeve 32;

[0028] The clamping sleeve 32 includes an interlayer shell 321, a transfer sleeve 322 is fixedly connected to the axis of the outer surface of the interlayer shell 321 through a through hole, a side circular rail 323 is fixedly connected to the side of the outer surface of the interlayer shell 321 away from the transfer sleeve 322, a buffer baffle 324 is fixedly connected to the side of the inner wall of the interlayer shell 321 close to the transfer sleeve 322, and the inner layer of the buffer baffle 324 is covered with a circle of sponge gaskets for isolating the two sides of the interlayer shell 321, and the inner cavity of the interlayer shell 321 is evenly provided with modified clamps 4;

[0029] The modified splint 4 includes a wall-attached fixing plate 41, the inner cavity of the wall-attached fixing plate 41 is evenly provided with fixed through-tubes 42, the end of the fixed through-tube 42 away from the wall-attached fixing plate 41 is slidably connected to a sliding sleeve 43, and the end of the sliding sleeve 43 away from the fixed through-tube 42 is fixedly connected to a clamping soft plate 44. The outer surface of the clamping soft plate 44 is symmetrically provided with cross folding grooves on both sides, and each clamping soft plate 44 is divided into four areas by the cross folding grooves, such as Figure 5 As shown, through the cross folding groove, the clamping soft plate 44 in each area can bend and deform slightly relative to each other, the outer surface of the sliding sleeve 43 is slidingly connected to the inner cavity of the sandwich cylinder shell 321 through the socket, the outer surface of the wall-attached fixing plate 41 is fixedly connected to the inner cavity of the sandwich cylinder shell 321, the outer surface of the fixed through pipe 42 is fixedly connected to the inner cavity of the wall-attached fixing plate 41, the wall-attached fixing plate 41 is attached to the inner wall of the sandwich cylinder shell 321, and has a certain distance from the outer wall of the sandwich cylinder shell 321, so as to ensure that the air pressure can enter the sliding sleeve 43 through the fixed through pipe 42.

[0030] After the device is set up, the robot workpiece to be welded is first placed on the auxiliary support 2 in the middle for lifting, and then clamped by the clamping components 3 on both sides, and then the relevant welding equipment performs welding on the workpiece.

[0031] The clamping sleeve 32 of the device clamps the side of the workpiece through the modified clamping plate 4 arranged on the inner wall. After the side of the workpiece is inserted into the interior of the interlayer shell 321, it is first blocked by the buffer baffle 324 for limiting. After the interlayer shells 321 on both sides press the workpiece through the buffer baffle 324, the pressure pump 15 pressurizes all the modified clamping plates 4 inside the interlayer shell 321 to restart the work. At this time, the air pressure pushes each sliding sleeve 43 through the fixed through pipe 42, so that the sliding sleeve 43 pushes the clamping soft plate 44 in the corresponding area to separate into blocks. Since the shape of the workpiece may be an arc, When the resistance encountered by the block of the clamping soft plate 44 is small, it means that the block here is at a certain distance from the contact surface of the workpiece. Therefore, under the action of air pressure, the sliding sleeve 43 here will be pushed farther, so that the block of the clamping soft plate 44 here can also fit the outer surface of the workpiece. Since the clamping soft plates 44 are connected together as a whole due to the cutting grooves, they can be approximately regarded as wrapping the workpiece. Therefore, the clamping force of each clamping soft plate 44 on the workpiece will not be too dispersed, thereby ensuring that the modified clamping plate 4 can quickly adapt to the shape of the outer surface of the workpiece when clamping workpieces with different outer surfaces, thereby achieving a tightening clamping effect.

[0032] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the guide component 1 includes a base sliding shell 11, a dust collecting bottom machine 12 is symmetrically arranged on the left and right sides of the inner wall of the base sliding shell 11, an auxiliary support 2 is arranged in the middle of the base sliding shell 11, a thrust sleeve 16 is symmetrically arranged on the front and rear sides of the outer surface of the base sliding shell 11, a connecting slide 13 is symmetrically arranged on the left and right sides of the inner wall of the thrust sleeve 16, a torque sleeve 14 is fixedly connected to the top of the connecting slide 13, a pressure pump 15 is rotatably connected to the inner wall of the torque sleeve 14, and the torque sleeve 14 can drive the sandwich shell 321 on the connected side to rotate by twisting the pressure pump 15. The outer surface of the pressure pump 15 is fixedly connected to the inner wall of the adapter sleeve 322, the number of the connecting slides 13 is four, the outer surface of the thrust sleeve 16 is fixedly connected to the outer surface of the base sliding shell 11, and the outer surface of the connecting slide 13 is slidably connected to the inner wall of the thrust sleeve 16.

[0033] The lifting base 31 includes a built-in slide cylinder 311, the upper surface of which is evenly provided with embedded balls 312 through a rotating groove, the inner wall of the built-in slide cylinder 311 is slidably connected with a vertical slide rod 313, the top of the vertical slide rod 313 is provided with a docking sleeve 314, and the lower part of the outer surface of the vertical slide rod 313 is symmetrically provided with a concave rotating wheel 317. When the concave rotating wheel 317 rotates, the vertical slide rod 313 can be driven by friction to slide up and down along the built-in slide cylinder 311 relatively, and independent motors 316 are symmetrically provided on the front and rear sides of the outer surface of the concave rotating wheel 317. The outer surface of the independent motor 316 is fixedly connected with a centralized connecting plate 315, and the bottom end of the vertical slide rod 313 is embedded with balls to ensure that less wear is generated when it contacts the bottom of the inner wall of the base slide shell 11.

[0034] The top of the concentrated connecting plate 315 is fixedly connected to the lower surface of the built-in slide cylinder 311, the upper surface of the built-in slide cylinder 311 is slidably connected to the top of the inner wall of the base slide shell 11 through the embedded ball 312, the axis of the outer surface of the built-in slide cylinder 311 is slidably connected to the axis of the inner wall of the base slide shell 11 through the guide slide groove, the outer surface of the concave rotating wheel 317 is rollingly connected to the outer surface of the vertical slide rod 313, and the top of the vertical slide rod 313 is slidably connected to the inner wall of the side circular rail 323 through the docking sleeve 314.

[0035] The auxiliary support 2 includes a control base plate 21, and support frames 22 are symmetrically arranged on the front and rear sides of the inner cavity of the control base plate 21. A central support plate 23 is fixedly connected to the top of the support frame 22. Extended support plates 24 are symmetrically arranged on the left and right sides of the inner wall of the central support plate 23. The extended support plates 24 on both sides can be extended and slid along the slide groove of the central support plate 23, thereby expanding the actual lifting area of ​​the central support plate 23.

[0036] The side thrust component 33 includes a compression push cylinder 331, the right end of which is fixedly connected to a fixed disk shell 332, a pressure-bearing washer 333 is fixedly connected to the inner wall of the fixed disk shell 332, spring compression rods 334 are evenly arranged on the side of the pressure-bearing washer 333, and a connecting wire 335 is fixedly connected to the axis of the inner cavity of the pressure-bearing washer 333. One end of the spring compression rod 334 away from the pressure-bearing washer 333 extends to the outside of the fixed disk shell 332 through a through hole, and one end of the compression push cylinder 331 away from the fixed disk shell 332 is fixedly connected to the axis of the inner wall of the interlayer cylinder shell 321, and the outer surface of the fixed disk shell 332 and the axis of the inner wall of the buffer baffle 324 are pressed against each other.

[0037] When welding, the slag and toxic gas generated by welding will be drained and adsorbed by the dust suction machine 12 on both sides of the inner wall of the base sliding shell 11, so as to avoid the problem of random diffusion of residual material and residue. The thrust sleeve 16 drives the clamping sleeve 32 to slide along the slide groove at the top of the inner wall of the base sliding shell 11 by pulling the sliding plates 13 on both sides. The torque sleeve 14 can directly twist the side of the pressure pump 15, thereby driving the clamping sleeve 32 to twist its clamping part, and then adjusting the welding angle of the clamping part to avoid welding dead angles.

[0038] When the clamping sleeve 32 slides left and right to adjust the distance with the clamping part, the built-in slide cylinder 311 at the bottom thereof always slides against the top of the inner wall of the base slide shell 11 through the embedded ball 312. When the clamping sleeve 32 needs to be adjusted in height, the concave rotating wheel 317 at the bottom rolls under the control of the independent motor 316, and uses the strong friction force to drive the vertical slide bar 313 to slide up and down along the inner wall of the built-in slide cylinder 311, thereby adjusting the actual height of the clamping sleeve 32. When the torque sleeve 14 twists the clamping sleeve 32, the clamping sleeve 32 will rotate relatively along the outer surface of the docking sleeve 314 through the side circular rail 323 on the outer surface. When rotating through the preset slide rail groove, the lifting base 31 is always located directly below and will not interfere with the twisting movement of the clamping sleeve 32.

[0039] After welding is completed, the clamping sleeve 32 will place the workpiece on the center support plate 23. At this time, the workpiece is being welded and its center of gravity may shift, so the extended support plates 24 on both sides need to be pulled apart so that the center support plate 23 with extended length can stably support the welded workpiece. Then the pressure pump 15 relieves the pressure in the inner cavity of the interlayer shell 321 to separate the modified clamping plate 4 from the outer surface of the workpiece. After pulling apart the clamping sleeve 32, a welded robot workpiece is obtained.

[0040] After the booster pump 15 is working, the compression push cylinder 331 located at the axial center of the inner wall of the sandwich shell 321 will expand under the pressure. Figure 8 As shown, at this time, the fixed disk shell 332 will move toward the side of the axis of the buffer baffle 324, and then the fixed disk shell 332 and the axis of the buffer baffle 324 will complement each other, and the spring compression rod 334 will also be squeezed against the side of the workpiece, thereby squeezing the spring compression rod 334 toward the side of the pressure washer 333. At this time, the spring compression rod 334 is pressed for a distance. When the clamped workpiece and the clamping sleeve 32 become loose, the spring compression rod 334 pressed somewhere will also reduce the pressing force on the pressure washer 333 due to the looseness, thereby timely detecting the problem of loosening of the clamped workpiece.

[0041] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
