Description
Technical Field
[0001] The invention provides a disassembly tool, which relates to the technical field of mechanical engineering, and in particular to a special tool for disassembling a reversing valve of a glue spraying machine. Background Art
[0002] The imported glue spraying machine is a special equipment used to bond the composite panels of refrigerated trucks. The reversing valve, as the core component, needs to replace the valve core sealing ring frequently due to frequent work. However, the valve cover is flush with the end face of the valve body and can only be disassembled through the two disassembly holes set on the valve cover. Insert the two attached round rods into the holes, and use a crowbar to rotate counterclockwise along the circumference with the round rods as the fulcrum to remove the valve core cover.
[0003] The prior art cannot remove the valve core cover when replacing the valve core sealing ring, and the cost of replacing the reversing valve as a whole is very high. In addition, the long replacement cycle affects production. The cylindrical crowbar type disassembly provided by foreign equipment manufacturers is difficult and can easily cause mechanical damage. The disassembly process requires the round rod to be firmly inserted. The crowbar is easy to slip during the disassembly process, which can easily hurt people and pose a huge safety hazard.
[0004] In view of the above problems, technicians in this field have proposed a special tool for disassembling the reversing valve of the imported glue spraying machine, which can realize the labor-saving disassembly of the sealing ring of the reversing valve of the glue spraying machine, which not only saves replacement time, but also ensures a safe and reliable working environment. Summary of the invention
[0005] In view of the shortcomings of the prior art, the present invention provides a special tool for disassembling the reversing valve of a glue spraying machine. A more convenient and quick disassembly tool is designed that can prevent the metal rod from slipping and is used for disassembling the reversing valve of the glue spraying machine. It does not increase the operating trouble when used, and can avoid the slipping of the crowbar and the metal rod as much as possible. The metal bell set on the wrench can also ensure that the reversing valve is not prone to thread slippage.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a special tool for disassembling the reversing valve of a glue spraying machine, including a tightening hexagon socket bolt and a wrench. The tightening hexagon socket bolt is adapted to the disassembly hole as a substitute for the round rod, and the wrench applies a thrust to the valve core cover plate by tightening the hexagon socket bolt, thereby avoiding the problem of easy slippage between the crowbar, metal rod and the disassembly hole of the valve core cover plate in the existing disassembly tool. The force and coordination between the tightening hexagon socket bolt and the valve core cover plate and between the tightening hexagon socket bolt and the wrench are more stable.
[0007] A friction pressure plate is clamped at one end of the wrench, and four clamping hexagon socket bolts are fixed in a rectangular shape on one side of the friction pressure plate. The force between the wrench and the valve core cover plate is transmitted through the four clamping hexagon socket bolts arranged in a rectangular shape, and the transmission path is more stable.
[0008] The wrench comprises a crowbar end, the end of the crowbar end is hingedly connected with a clamping end corresponding to the friction pressure plate, and a spring is arranged at the connection between the crowbar end and the clamping end.
[0009] The crowbar end extends the length of the force-bearing rod, thereby increasing the force multiples. The clamping end clamps the friction pressure plate to prevent slipping. A spring is arranged at the connection between the crowbar end and the clamping end to monitor the force changes of the tightening hexagon socket bolt to prevent damage to the thread of the valve core cover plate.
[0010] The four tightening hexagon socket bolts are inserted into the disassembly holes on the side of the valve core cover plate in a rectangular shape, and then the friction pressure plate is installed to the ends of the four tightening hexagon socket bolts exposed from the valve core cover plate. The wrench clamps the friction pressure plate through the clamping end, and pushes the crowbar end to apply pressure in the direction of the compression spring, thereby realizing the disassembly and assembly of the valve core cover plate.
[0011] Preferably, a unloading block is fixed to the disassembly hole corresponding to the side of the clamping hexagon socket bolt, and the unloading blocks on the sides of the four clamping hexagon socket bolts are in contact and pressed against each other. The unloading block not only increases the force contact area between the clamping hexagon socket bolt and the valve core cover plate, but also realizes balanced transmission of force between the four clamping hexagon socket bolts, thereby avoiding damage to a single clamping hexagon socket bolt due to quality or uneven force problems.
[0012] A mounting groove is provided on the side of the friction pressure plate corresponding to the unloading block. The friction pressure plate is installed in a limited position through the mounting groove and four tightening hexagon socket bolts, which increases the effective contact area, thereby reducing local force and increasing the stability of equipment installation.
[0013] Preferably, a force sleeve is slidably sleeved on the side of the crowbar end, and the extension length of the crowbar end is extended by the force sleeve, which not only helps to shorten the actual length of the wrench, but also facilitates labor saving when using the tool.
[0014] The side of the force sleeve is hinged with a buckle, and the extension and retraction of the force sleeve are positioned by the buckle, which facilitates the control and use of the wrench.
[0015] Preferably, a slot is provided through the side of the force sleeve, and the buckle is hingedly arranged on the inner side of the slot through an elastic member, and limiting wedge blocks are fixed corresponding to the crowbar end and the side of the buckle, and the elastic member is compressed by pressing the buckle, thereby controlling the positioning state of the hinged buckle on the force sleeve.
[0016] Preferably, a hexagonal prism is fixed to the side surface of the friction pressure plate corresponding to the clamping end, and the installation stability between the wrench and the clamping hexagon socket bolt is increased by the hexagonal prism.
[0017] A protrusion is fixed on the inner side of the clamping end, and a bayonet is reserved on the side of the hexagonal prism close to one end of the friction pressure plate corresponding to the protrusion. The protrusion cooperates with the bayonet to facilitate positioning between the wrench and the clamping hexagon socket bolt to prevent slipping.
[0018] Preferably, a slide rail is fixed to one end of the crowbar end close to the clamping end corresponding to the hinge shaft, a slider is fixed to the end of the clamping end corresponding to the slide rail, and the crowbar end and the clamping end are slidably clamped via the slide rail slider.
[0019] One side of the crowbar end and the clamping end is hinged and rotated, and the other side is rotatably installed within a limited range through the cooperation of the slide rail and the slider, which not only avoids the inconvenience of using the simply hinged wrench, but also facilitates the spring set between the crowbar end and the clamping end to monitor the force changes.
[0020] Preferably, a screw is fixed to one end of the crowbar end and the clamping end close to each other, and the spring is sleeved on the side of the extended end of the screw. The spring is positioned and installed by the screw to prevent the spring from being compressed, deformed, and popping out to affect monitoring.
[0021] The side surface of one end of the screw rod is fixed and pressed against the end of the spring, and a tightening nut is also threadedly sleeved thereon. The tightening nut is used to facilitate supplementary adjustment of the spring when the elastic coefficient of the spring is greatly attenuated.
[0022] Preferably, an L-shaped rod is fixed on the side of the screw rod, and the extended end of the L-shaped rod is arranged parallel to the spring. A metal bell is sleeved on the side of the L-shaped rod. When the wrench is in use, the crowbar end applies pressure to the clamping end through the spring. After the valve core cover plate is tightened, the reaction force further squeezes the spring to trigger the metal bell, and then stops the continued force in time to avoid damaging the thread of the valve core cover plate.
[0023] Preferably, a fixing rod is fixedly connected to the side of the metal bell, and a lever is hingedly provided at the end of the fixing rod corresponding to the metal bell. The installation position of the metal bell on the side of the L-shaped rod is adjusted together with the tightening nut. When the elastic force of the spring exceeds the set value, the metal bell is triggered by the lever to produce a warning sound.
[0024] Preferably, a positioning block is connected to the threaded sleeve of the lever corresponding to the side of the fixed rod. When the elastic coefficient of the spring changes, its compressed length and elastic force also change accordingly. The limiting angle of the lever is adjusted by the positioning block, thereby calibrating the triggering elastic force of the metal bell.
[0025] The invention discloses a special tool for disassembling a reversing valve of a glue spraying machine, which has the following beneficial effects:
[0026] 1. The special tooling for disassembling the reversing valve of the glue spraying machine replaces the metal rod of the prior art by tightening the hexagon socket bolts, and then pushes the valve core cover to rotate through the wrench and the friction pressure plate. On the one hand, it can avoid the problem of easy slippage between the metal rod and the valve core cover, and between the metal rod and the crowbar in the existing disassembly tooling, which may cause danger. In addition, a spring and a metal bell are arranged on the side of the wrench to monitor the force change of the valve core cover, and the force can be stopped in time after hearing the prompt tone to avoid the problem of valve core cover thread slippage. In addition, the emergence of this professional tooling can shorten the disassembly time of the reversing valve of the glue spraying machine and avoid production delays.
[0027] 2. The glue spraying machine reversing valve disassembly tooling has four tightening hexagon socket bolts inserted into the side of the valve core cover in a rectangular shape. The four tightening hexagon socket bolts interact and transmit the force through the side unloading blocks to avoid damage caused by process errors of individual tightening hexagon socket bolts. At the same time, the effective contact area between the valve core cover and the wrench is increased, making the use of the tooling more stable and labor-saving.
[0028] 3. The glue spraying machine reversing valve is disassembled with a special tool. The wrench is set to a structure in which the crowbar end and the clamping end are hinged, and the connection between the slide rail and the slider is set at a symmetrical hinge point, so that there is a local activity space between the clamping end and the crowbar end. When pressure is applied to the clamping end through the crowbar end, the force applied to the valve core cover plate is monitored by the change in the elastic force of the spring.
[0029] 4. The glue spraying machine reversing valve is disassembled with special tooling. The metal bell is set on one side of the spring through the sliding of the L-shaped rod. As the spring elastic coefficient changes, the triggering of the metal bell can be adjusted and calibrated to ensure accurate force monitoring of the valve core cover.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are 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] The embodiment of the present invention discloses a special tool for disassembling a reversing valve of a glue spraying machine;
[0041] According to the attached Figure 1 As shown, it includes a clamping hexagon socket bolt 1 and a wrench 2. The clamping hexagon socket bolt 1 is adapted to the disassembly hole as a substitute for the round rod. The wrench 2 applies a thrust to the valve core cover plate by clamping the hexagon socket bolt 1, thereby avoiding the problem of easy slippage between the crowbar, metal rod and the disassembly hole of the valve core cover plate in the existing disassembly tooling. The force and coordination between the clamping hexagon socket bolt 1 and the valve core cover plate and between the clamping hexagon socket bolt 1 and the wrench 2 are more stable.
[0042] A friction pressure plate 3 is clamped at one end of the wrench 2, and four clamping hexagon socket bolts 1 are fixed in a rectangular shape on one side of the friction pressure plate 3. The force between the wrench 2 and the valve core cover plate is transmitted through the four clamping hexagon socket bolts 1 arranged in a rectangular shape, and the transmission path is more stable.
[0043] According to the attached Figure 2 As shown, the wrench 2 includes a crowbar end 201 , the end of the crowbar end 201 is hingedly connected to a clamping end 202 corresponding to the friction pressure plate 3 , and a spring 203 is provided at the connection between the crowbar end 201 and the clamping end 202 .
[0044] The crowbar end 201 extends the length of the force-bearing rod, thereby increasing the force multiples. The clamping end 202 clamps the friction pressure plate 3 to prevent slipping. A spring 203 is arranged at the connection between the crowbar end 201 and the clamping end 202 to monitor the force changes of the tightening hexagon socket bolt 1 to prevent damage to the thread of the valve core cover plate.
[0045] Four tightening hexagon socket bolts 1 are inserted into the disassembly holes on the side of the valve core cover plate in a rectangular shape, and then the friction pressure plate 3 is installed to the ends of the four tightening hexagon socket bolts 1 exposed from the valve core cover plate. The wrench 2 clamps the friction pressure plate 3 through the clamping end 202, and pushes the crowbar end 201 to apply pressure in the direction of the compression spring 203, thereby realizing the disassembly and assembly of the valve core cover plate.
[0046] According to the attached Figure 3 As shown, a force unloading block 4 is fixed to the disassembly hole corresponding to the side of the clamping hexagon socket bolt 1, and the force unloading blocks 4 on the sides of the four clamping hexagon socket bolts 1 are in contact and pressed against each other. The force unloading block 4 not only increases the force contact area between the clamping hexagon socket bolt 1 and the valve core cover plate, but also realizes the balanced transmission of force between the four clamping hexagon socket bolts 1, thereby avoiding damage to a single clamping hexagon socket bolt 1 due to quality or uneven force problems.
[0047] A mounting groove 5 is provided on the side of the friction pressure plate 3 corresponding to the unloading block 4. The friction pressure plate 3 is limitedly installed through the mounting groove 5 and four tightening hexagon socket bolts 1, which increases the effective contact area, thereby reducing local force and increasing the stability of equipment installation.
[0048] A hexagonal prism 10 is fixed to the side surface of the friction pressure plate 3 corresponding to the clamping end 202 , and the hexagonal prism 10 increases the installation stability between the wrench 2 and the clamping hexagon socket bolt 1 .
[0049] A protrusion 11 is fixed on the inner side of the clamping end 202, and a bayonet is reserved on the side of the hexagonal prism 10 close to the friction pressure plate 3 corresponding to the protrusion 11. The protrusion 11 cooperates with the bayonet to facilitate the positioning between the wrench 2 and the tightening hexagon socket bolt 1 to prevent slipping.
[0050] According to the attached Figure 4 As shown, a force sleeve 6 is slidably sleeved on the side of the crowbar end 201, and the extension length of the crowbar end 201 is extended by the force sleeve 6, which not only helps to shorten the actual length of the wrench 2, but also saves effort when using the tool.
[0051] A buckle 7 is hingedly provided on the side of the force sleeve 6 , and the extension and retraction of the force sleeve 6 are positioned by the buckle 7 , which facilitates the control and use of the wrench 2 .
[0052] Preferably, a slot 8 is penetrated through the side of the force sleeve 6, and the buckle 7 is hingedly arranged on the inner side of the slot 8 through an elastic member. A limiting wedge block 9 is fixed corresponding to the crowbar end 201 and the side of the buckle 7. The elastic member is compressed by pressing the buckle 7, thereby controlling the positioning state of the hinged buckle 7 on the force sleeve 6.
[0053] According to the attached Figure 5 As shown, a slide rail 12 is fixed to one end of the crowbar end 201 close to the clamping end 202 corresponding to the hinge axis, and a slider 13 is fixed to the end of the clamping end 202 corresponding to the slide rail 12 , and the crowbar end 201 and the clamping end 202 are slidably clamped through the slide rail 12 and the slider 13 .
[0054] One side of the crowbar end 201 and the clamping end 202 is hinged and rotated, and the other side is rotated within a limited range through the cooperation of the slide rail 12 and the slider 13. This not only avoids the inconvenience of using the simply hinged wrench 2, but also makes it convenient to monitor the force changes of the spring 203 set between the crowbar end 201 and the clamping end 202.
[0055] According to the attached Figure 6 As shown, a screw rod 14 is fixed to one end of the crowbar end 201 and the clamping end 202 close to each other, and a spring 203 is sleeved on the side of the extended end of the screw rod 14. The spring 203 is positioned and installed by the screw rod 14 to prevent the spring 203 from being compressed, deformed, and popping out to affect monitoring.
[0056] The side surface of one end of the screw rod 14 is fixed and pressed against the end of the spring 203 , and a tightening nut 15 is also threadedly sleeved. The tightening nut 15 is convenient for supplementary adjustment of the spring 203 when its elastic coefficient is greatly attenuated.
[0057] Preferably, an L-shaped rod 16 is fixed to the side of the screw rod 14 , and the extended end of the L-shaped rod 16 is arranged parallel to the spring 203 .
[0058] According to the attached Figure 7 As shown, a metal bell 17 is provided on the side of the L-shaped rod 16. When the wrench 2 is used, the crowbar end 201 applies pressure to the clamping end 202 through the spring 203. After the valve core cover is tightened, the reaction force further squeezes the spring 203 to trigger the metal bell 17, thereby stopping the force in time to avoid damaging the thread of the valve core cover.
[0059] Preferably, a fixing rod 18 is fixedly connected to the side of the metal bell 17, and a lever 19 is hingedly provided at the end of the fixing rod 18 corresponding to the metal bell 17. The installation position of the metal bell 17 on the side of the L-shaped rod 16 is adjusted together with the tightening nut 15. When the elastic force of the spring 203 exceeds the set value, the metal bell 17 is triggered by the lever 19 to produce a warning sound.
[0060] Preferably, a positioning block 20 is threadedly connected to the side of the fixed rod 18 corresponding to the lever 19. When the elastic coefficient of the spring 203 changes, its compressed length and elastic force also change accordingly. The limiting angle of the lever 19 is adjusted by the positioning block 20, thereby calibrating the triggering elastic force of the metal bell 17.
[0061] The special tooling for disassembling the reversing valve of the glue spraying machine replaces the metal rod of the prior art by tightening the hexagon socket bolt 1, and then pushes the valve core cover plate to rotate through the wrench 2 and the friction pressure plate 3. On the one hand, it can avoid the problem of easy slippage between the metal rod and the valve core cover plate, and between the metal rod and the crowbar in the prior art disassembly tooling, and cause danger. In addition, a spring 203 and a metal bell 17 are arranged on the side of the wrench 2, which can monitor the force change of the valve core cover plate, and can stop applying force in time after hearing the prompt sound to avoid the problem of valve core cover plate thread slippage. In addition, the emergence of this professional tooling can shorten the time consumed in disassembling the reversing valve of the glue spraying machine and avoid delays in production.
[0062] Furthermore, four clamping hexagon socket bolts 1 are inserted into the side of the valve core cover plate in a rectangular shape, and the four clamping hexagon socket bolts 1 interact and transmit the force through the side unloading blocks 4, thereby avoiding damage caused by process errors of individual clamping hexagon socket bolts 1, and at the same time increasing the effective contact area between the valve core cover plate and the wrench 2, thereby making the use of the tooling more stable and labor-saving.
[0063] Furthermore, the wrench 2 is configured as a structure in which the crowbar end 201 and the clamping end 202 are hinged, and a connection is provided between the slide rail 12 and the slider 13 at symmetrical hinge points, so that there is a local movable space between the clamping end 202 and the crowbar end 201. When pressure is applied to the clamping end 202 by the crowbar end 201, the magnitude of the force applied to the valve core cover plate is monitored by the change in the elastic force of the spring 203.
[0064] Furthermore, the metal bell 17 is slidably arranged on one side of the spring 203 through the L-shaped rod 16. As the elastic coefficient of the spring 203 changes, the triggering of the metal bell 17 can be conveniently adjusted and calibrated to ensure accurate monitoring of the force on the valve core cover.
[0065] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
