Description

Technical Field

[0001] The invention relates to the technical field of hard alloy plate processing, in particular to a hard alloy plate welding tool. Background Art

[0002] Cemented carbide plate is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. This material has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. The main components of cemented carbide plates include tungsten carbide and cobalt. The content of tungsten carbide and cobalt in cemented carbide plates for different purposes is not consistent, and the scope of use is extremely wide. Cemented carbide plates are named because of their rectangular plate (or block) shape. They have excellent hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid, alkali, high temperature oxidation resistance), low impact toughness, low expansion coefficient, and thermal and electrical conductivity similar to iron and its alloys. These characteristics make cemented carbide plates an excellent material for making high temperature resistant parts, wear resistant parts, anti-shielding parts, and corrosion resistant parts.

[0003] When welding carbide plates, a three-dimensional flexible welding platform is generally used. The three-dimensional flexible welding platform has a high load-bearing capacity and stable rigidity. The welding platform can be freely extended and expanded like building blocks for combination and splicing. The standard tabletop that is expanded as needed can be modularly positioned and connected with fixtures. The function of the flexible three-dimensional welding platform can be fully demonstrated in the process of installing, adjusting and positioning the workpiece, maximizing its function, which is very convenient in the application of large workpieces.

[0004] However, in the prior art, although the evenly distributed holes of the three-dimensional flexible welding platform can fix different types of repeatedly used modules and fixtures to position the carbide plate and use them flexibly, the positioning principle of the welding fixture is to use the positioning components of the fixture, such as positioning holes, positioning pins, etc., to accurately position the workpiece in the fixture, that is, it is achieved by threaded connection. If multiple parts are selected for assistance, the staff is required to screw multiple fixtures on the welding platform at the same time, and in order to fix them more stably, the twisting operation needs to be repeated to adjust the position of the fixture, and the overall operation is too complicated.

[0005] To this end, we have developed a new carbide plate welding tool. Summary of the invention

If multiple parts are selected for assistance, the staff is required to screw multiple fixtures on the welding platform at the same time, and in order to fix them more stably, the twisting operation needs to be repeated to adjust the position of the fixture, and the overall operation is too complicated.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Examples, such as Figure 1 - Fig. 9As shown, an embodiment of the present invention provides a cemented carbide plate welding tool, including a welding platform 5, the outer surface of the welding platform 5 is provided with a through slide groove 6, the inner wall of the slide groove 6 is slidably connected to two sliders 7, one side of the outer surface of the two sliders 7 is commonly fixedly connected to a support plate 8, a displacement mechanism is installed on the top of the support plate 8, one end of the displacement mechanism is rotatably connected to a first mounting plate 15, the lower surface of the first mounting plate 15 is slidably connected to the upper surface of the welding platform 5, and one end of the top of the first mounting plate 15 is hinged to a second mounting plate 16, one end of the second mounting plate 16 is installed with a positioning component, and a rotation limit component is symmetrically installed at the hinge of the second mounting plate 16 and the first mounting plate 15;

[0041] like Figure 2 As shown, a plurality of positioning holes 29 are provided on the upper surface of the welding platform 5. The positioning holes 29 can facilitate the fixing and adjustment of the welding electrodes, and facilitate the installation of different welding fixtures on the welding platform through the positioning holes to fix the carbide plate and ensure the stability and reliability of the welding process. At the same time, oxides will be generated during the metal welding process, and the positioning holes 29 can also play a role in discharging oxides to prevent the oxides from being accumulated and affecting the welding quality.

[0042] like Figure 3 As shown, the displacement mechanism includes a fixing sleeve 11 fixedly connected to the center position of the upper surface of the support plate 8, a mounting rod 12 is fixedly connected to the inner side of the fixing sleeve 11, one end of the mounting rod 12 is rotatably connected to a turning handle 13, and the mounting rod 12 and the turning handle 13 are both hollow structures, and a first screw 14 is slidably connected to the inside of the mounting rod 12, the outer surface of the first screw 14 is threadedly connected to the inner wall of the turning handle 13, and one end of the first screw 14 is rotatably connected to the first mounting plate 15, and the first screw 14 can be driven to be screwed out from the inside of the mounting rod 12 by rotating the turning handle 13, so that the first mounting plate 15 at the end of the first screw 14 slides along the upper surface of the welding platform 5, and the first mounting plate 15 is changed to change the position of the positioning assembly, so that the staff can position the cemented carbide plate;

[0043] At the same time, the outer surface of the turning handle 13 is provided with anti-slip grooves. The anti-slip design of the surface can significantly reduce the number of operating errors. During operation, since the palms are prone to sweating, if there is no anti-slip design, it may cause hand slippage, which in turn leads to operating errors. The roughened anti-slip design can significantly increase the friction between the handle and the palm, effectively preventing slippage caused by sweat or slippery environment, and ensuring that the staff can grasp and control it stably.

[0044] like Figure 4 and Figure 6As shown, the positioning assembly includes a positioning plate 18 fixedly connected to the top of one side of the outer surface of the second mounting plate 16, a second screw 20 is threadedly connected to the side wall of the positioning plate 18, a turning handle 19 is fixedly connected to the upper surface of the second screw 20, a positioning rod 30 is inserted into the lower surface of the second screw 20, a fixed end 21 is fixedly connected to the lower surface of the positioning rod 30, and a fixed plate 22 is fixedly connected to the lower surface of the fixed end 21, and the second screw 20 can be driven to move relative to the side wall of the positioning plate 18 by twisting the turning handle 19, thereby interfering with the displacement of the fixed plate 22 at the bottom of the second screw 20, so that the fixed plate 22 can be pressed against the surface of the carbide plate according to the use needs to limit and lock it;

[0045] like Figure 7 and Figure 8 As shown, the positioning assembly also includes a protrusion 32 symmetrically slidably connected to the top of the side wall of the positioning rod 30, and a second spring 31 is fixedly connected between the two protrusions 32 and the side wall of the positioning rod 30, and the outer surfaces of the two protrusions 32 are both smooth arc structures. By pulling the positioning rod 30 downward, the positioning rod 30 will drive the protrusion 32 to move downward, and the protrusion 32 will be pushed back to the inside of the side wall of the positioning rod 30 due to its smooth arc structure. The displacement of the positioning rod 30 will not be hindered. When the positioning rod 30 is taken out, the connection between the positioning rod 30 and the second screw 20 is released, so that the fixing plate 22 can be replaced. Specifically, in actual application, fixing plates 22 of different shapes can be designed, such as fixing plates 22 with a certain inclination angle or special shape, so as to meet the positioning requirements of cemented carbide plates of different shapes during welding, and the overall use is more flexible.

[0046] At the same time, by adopting the method of threaded connection between the second screw 20 and the side wall of the positioning plate 18, the second screw 20 has a self-locking characteristic, which can effectively prevent the relative rotation of the thread pair during use, thereby avoiding the change in the height of the fixing plate 22, and ensuring the stable operation of the welding process. In addition, the locking of the second screw 20 can also enhance the structural strength of the mechanical equipment, reduce the displacement or falling off of components caused by vibration or external force, and further improve the safety and reliability of the equipment;

[0047] Furthermore, during the tightening process of the second screw 20, by controlling the tightening degree of the second screw 20, it is possible to ensure that the force between the second screw 20 and the connecting piece is balanced, thereby preventing the second screw 20 from entering a yield stage due to excessive tightening, causing irreversible deformation or failure, or even excessive pressure on the carbide plate to cause wear on its surface, thereby ensuring that the carbide plate will not affect the final product during welding.

[0048] like Fig. 9As shown, the rotation limit assembly includes a support plate 23 fixedly connected to one side of the top of the outer surface of the first mounting plate 15 and a rotating sleeve 24 fixedly connected to one side of the bottom of the outer surface of the second mounting plate 16, the upper surface of the support plate 23 is slidably connected with a sliding sleeve 17, and the end of the sliding sleeve 17 close to the rotating sleeve 24 is fixedly connected with a clamping block 33, and the clamping block 33 is clamped at the end of the rotating sleeve 24 close to the sliding sleeve 17, wherein one end of the rotating sleeve 24 is provided with two clamping grooves matching the clamping block 33, and the connecting line of the two clamping grooves is at an angle of 90°, so that the clamping of the clamping block 33 with the two clamping grooves corresponds to different states between the rotating sleeve 24 and the sliding sleeve 17 respectively;

[0049] Correspondingly, the rotation limit assembly also includes an insertion rod 25 that passes through and is fixedly connected to the inside of the sliding sleeve 17. One end of the insertion rod 25 is inserted into the inside of the rotating sleeve 24, and the outer surface of the insertion rod 25 is sleeved and fixedly connected with a first spring 27. At the same time, a cavity 26 that matches the insertion rod 25 is provided inside the rotating sleeve 24, and a slot 28 that matches the insertion rod 25 is provided inside the sliding sleeve 17, that is, the insertion rod 25 is fixedly connected to the inside of the sliding sleeve 17 through the slot 28, and the sliding sleeve 17 can slide along the support plate 23. By pulling the sliding sleeve 17 to slide, the insertion rod 25 can be driven to compress the first spring 27;

[0050] Specifically, the block 33 is inserted into one of the two slots. At this time, the first mounting plate 15 and the second mounting plate 16 form a straight line together, that is, the two are aligned. At this time, if the sliding sleeve 17 is pulled to move, the engagement between the block 33 and the single slot is released, and then the second mounting plate 16 can be rotated to form a 90° angle with the first mounting plate 15. At this time, the first spring 27 is in a compressed state. When the second mounting plate 16 moves into place, the sliding sleeve 17 can be released. At this time, under the rebound force of the first spring 27, the block 33 is just inserted into another slot with an angle of 90° with the previous slot, so that the second mounting plate 16 is rotated 90° to present a state perpendicular to the first mounting plate 15, and this state is locked.

[0051] Furthermore, when the first mounting plate 15 and the second mounting plate 16 are perpendicular to each other, the positioning plate 18 will be parallel to the first mounting plate 15. At this time, the positioning component can be changed from the original vertical positioning of the carbide plate to the side positioning of the carbide plate, so that the two side surfaces of the carbide plate are respectively against the opposite sides of the first mounting plate 15 and the fixed plate 22, so as to realize the vertical placement and positioning of the carbide plate.

[0052] Preferably, the slot and the block 33 are arranged in a trapezoidal shape. The trapezoidal slot has good self-locking performance, which can prevent the workpiece from shifting or rotating during the manufacturing or processing process. At the same time, the trapezoidal slot has good stability and can ensure that the parts it clamps are not easy to slide under gravity.

[0053] like Figure 2 and Figure 5 As shown, the lower surface of the welding platform 5 is fixedly connected with support legs 1 all around, and a connecting plate 2 is fixedly connected between every two support legs 1 on the same side. The connecting plate 2 connects the two support legs together, and the overall structure is more stable, not easy to shake or tilt, and is safer and more reliable to use. At the same time, the one-piece design also reduces parts and connections, reduces the possibility of damage and wear, and increases the service life;

[0054] Further, the support leg 1 includes a base 101, a support main rod 102 and a support sub-rod 103, the support sub-rod 103 is fixedly connected to the lower surface of the welding platform 5, the support main rod 102 is sleeved and slidably connected to the outer surface of the support sub-rod 103, and the base 101 is fixedly connected to the lower surface of the support main rod 102, and the relative position between the support main rod 102 and the support sub-rod 103 is adjustable, that is, the length of the support leg 1 presented by the overall length of the support main rod 102 and the support sub-rod is adjustable, thereby lifting the welding platform 5 to different vertical heights;

[0055] Among them, the supporting leg 1 is made of high-strength material, has good wind resistance and stability, can remain stable in different environments, and ensures the safety and reliability of work. At the same time, the supporting leg 1 has a clear structure, and maintenance and use are very convenient. This simple design is not only easy to operate, but also reduces maintenance costs. The supporting leg 1 can adjust the height according to actual needs and can be suitable for different occasions and height requirements. This flexibility enables the lifting rod to easily adapt to various environments and usage conditions.

[0056] Furthermore, a plurality of insertion holes 4 are provided on one side of the outer surface of the supporting main rod 102 and the supporting auxiliary rod 103, and a fixing pin 3 is threadedly connected through the corresponding insertion holes 4 between the side walls of the supporting main rod 102 and the supporting auxiliary rod 103, wherein the inner wall of the insertion hole 4 is provided with an internal thread matching the fixing pin 3, so as to facilitate fixing the position of the fixing pin 3;

[0057] Correspondingly, the fixing pin 3 includes a knob 301, a connecting shaft 302 and a fixing rod 303. The fixing rod 303 is threadedly connected to the side walls of the supporting main rod 102 and the supporting auxiliary rod 103. The connecting shaft 302 is fixedly connected to one end of the fixing rod 303, and the knob 301 is fixedly connected to one end of the connecting shaft 302. The knob 301 is in the shape of a flower, which has both high aesthetics and decorativeness, and can add a sense of art and design to the product. It also has a large surface area and an easily recognizable shape, which is conducive to the staff to quickly and accurately find and operate the knob when using it. At the same time, it has good anti-slip and wear resistance, ensuring that the staff can operate conveniently and safely under various conditions. By rotating the flower-shaped knob 301, the fixing rod 303 can be tightened with the inner wall of the hole 4, thereby fixing the relative position of the supporting main rod 102 and the supporting auxiliary rod 103.

[0058] like Figure 3 As shown, a locking pin 10 is threadedly connected to one side of the outer surface of the support plate 8, and a threaded hole 9 matching the locking pin 10 is opened on the side wall of the support plate 8, and one end of the locking pin 10 is abutted against the outer surface of the welding platform 5 through the threaded hole 9. By tightening the locking pin 10 so that its end is tightly abutted against the outer surface of the welding platform 5, the position of the support plate 8 and the slider 7 relative to the slide groove 6 can be locked to prevent horizontal displacement when the carbide plate is positioned.

[0059] Working principle: First, the staff can hold the flower-shaped knob 301 to screw the fixing pin 3 out of the supporting main rod 102 and the supporting auxiliary rod 103, and adjust the length of the supporting leg 1 presented by the overall length of the supporting main rod 102 and the supporting auxiliary rod according to actual needs, and then lift the welding platform 5 to a suitable operating height for easy operation;

[0060] Then, the carbide plate can be placed on the surface of the welding platform 5, and the support plate 8 can be installed on the side of the appropriate welding platform 5 by sliding the slider 7 into the slide groove 6. By tightening the locking pin 10 so that its end is tightly against the outer surface of the welding platform 5, the position of the support plate 8 and the slider 7 relative to the slide groove 6 can be locked to prevent horizontal deviation when positioning the carbide plate.

[0061] Furthermore, by rotating the handle 13, the first screw rod 14 can be driven to be screwed out from the inside of the mounting rod 12, so that the first mounting plate 15 at the end of the first screw rod 14 slides along the upper surface of the welding platform 5, and the first mounting plate 15 is changed so that the position of the positioning assembly is located, and the first mounting plate 15 is pressed against the side of the cemented carbide plate, and then the upper surface or the side of the cemented carbide plate can be positioned according to the placement state of the cemented carbide plate;

[0062] Specifically, the first mounting plate 15 and the second mounting plate 16 together form a straight line, that is, the two are aligned. At this time, by turning the turning handle 19, the second screw rod 20 can be driven to move relative to the side wall of the positioning plate 18, thereby interfering with the displacement of the fixing plate 22 at the bottom of the second screw rod 20, so that the fixing plate 22 can be pressed against the surface of the hard alloy plate according to the use needs to limit and lock it;

[0063] On the contrary, by pulling the sliding sleeve 17 to move, the engagement between the clamping block 33 and the single clamping slot is released, and then the second mounting plate 16 can be rotated to form a 90° angle with the first mounting plate 15. At this time, the first spring 27 is in a compressed state. When the second mounting plate 16 moves into place, the sliding sleeve 17 can be released. At this time, under the resilience of the first spring 27, the clamping block 33 is just clamped into another clamping slot with an angle of 90° with the previous clamping slot, so that the second mounting plate 16 is rotated 90° to be perpendicular to the first mounting plate 15. At this time, the positioning assembly can change from the original vertical positioning of the carbide plate to the side positioning of the carbide plate, so that the two side surfaces of the carbide plate are respectively against the first mounting plate 15 and the opposite side of the fixed plate 22, so that the carbide plate is placed and positioned vertically;

[0064] After positioning the carbide plate by using a plurality of the above-mentioned devices, the welding operation can be performed. Accordingly, when the welding is completed, the above-mentioned steps can be reversed to remove the carbide plate from the welding platform 5;

[0065] During the whole process, the design of the slide groove 6 makes the change of the position of the support plate 8 more flexible, reduces the number of times the staff needs to tighten the bolts, makes the operation simpler, and makes the overall device more efficient. The first screw 14 can adjust the position of the first mounting plate 15 relative to the edge of the welding platform 5, so that the change of the position of the positioning component is also more flexible. The first mounting plate 15 can support the carbide plate on one side, and by changing the state between the sliding sleeve 17 and the rotating sleeve 24, the state between the first mounting plate 15 and the second mounting plate 16 can be changed. By using the state that the first mounting plate 15 and the second mounting plate 16 are vertical or in a straight line, the fixing plate 22 can support the other side of the carbide plate or vertically fix the surface of the carbide plate. The fixing method of the carbide plate is more flexible and changeable. A single device can achieve the clamping effect of multiple clamps on the carbide plate, which is more functional. At the same time, the carbide plate will not be offset or shaken to ensure welding quality and safety.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
