[0004] Regarding the above-mentioned related technologies, since the gearbox rear shell is heavy and irregular in shape, a hoist is generally used to lift the gearbox rear shell. During the process of lifting the gearbox rear shell, for example, when the gearbox rear shell needs to be installed on a tooling, the gearbox rear shell needs to be lifted onto supports and supports, and the gearbox rear shell is supported by the supports and supports. During this process, the gearbox rear shell is prone to tilt during the lowering process, causing the gearbox rear shell to collide with other components such as supports, thereby damaging the gearbox rear shell or tooling. Summary of the invention
[0005] In order to improve the convenience of disassembly and assembly during the processing of the gearbox casing and prevent the casing from being damaged by collision during hoisting, the present application provides a gearbox casing tooling that is easy to remove.
[0006] The present application provides a gearbox housing tooling that is convenient for taking out parts, which adopts the following technical solution: A gearbox housing tooling for easy removal of parts, comprising: A base plate is arranged horizontally; a plurality of support members are arranged on the base plate, one end of each support member abuts against a reference surface of the shell for supporting the shell; a plurality of positioning members are arranged on the base plate, one end of each positioning member is inserted into a first positioning hole of the shell for positioning the shell; a pressing component is arranged on the base plate, and the pressing component is used to lock the shell on the support member; a lifting component is arranged at the center of the plurality of support members, the lifting component comprises a first telescopic driving member and a lifting plate, the first telescopic driving member is arranged on the base plate, the lifting plate is arranged at the output end of the first telescopic driving member and the top surface of the lifting plate can support the shell, the first telescopic driving member can drive the lifting plate to lift so that the height of the top surface of the lifting plate is higher than the top height of the positioning member or the height of the top surface of the lifting plate is lower than the top height of the support member.
[0007] By adopting the above technical solution, the gearbox housing tooling significantly improves the convenience of disassembly and assembly during gearbox housing processing, and effectively prevents the shell from colliding with the support when hoisting the gearbox housing. Specifically, when the gearbox housing is installed on the tooling, the lifting plate is raised to a height just above the top of the support, so that when the gearbox housing is hoisted, the top surface of the lifting plate can bear the tilted shell and insert the positioning member into the first positioning hole of the shell to accurately position the shell, effectively preventing the gearbox housing from colliding with the support; after the gearbox housing is placed on the top surface of the lifting plate, the lifting plate is lowered to a height lower than the top of the support so that the shell can be stably supported by the support to reduce the shaking of the shell during processing; then, the pressing assembly presses down the shell and firmly locks the shell on the support to further prevent the shell from moving during processing. When the gearbox housing is removed from the tooling, the lifting plate is lifted to a height higher than the top of the positioning member to facilitate the lifting of the shell, preventing the shell from colliding with the support after the shell is tilted when lifting the gearbox housing, and solving the problem that the positioning member is engaged with the first positioning hole of the shell and affects the removal of the shell. Optionally, the gearbox housing tooling also includes a positioning assembly, the positioning assembly including a positioning base and a positioning pin, the positioning base is arranged on the base plate, a second guide hole is opened at the end of the positioning base facing away from the base plate, one end of the positioning pin is slidably inserted in the second guide hole, and the other end of the positioning pin can slide through the lifting plate and be inserted into the second positioning hole of the shell, and an elastic member is provided between the positioning pin and the second guide hole for making the positioning pin pop out in a direction away from the base plate.
[0008] By adopting the above technical solution, the positioning pin can quickly and preliminarily position the shell, simplifying the difficulty of the positioning member to position the shell; the positioning base can limit and guide the positioning pin to ensure the positioning accuracy of the positioning pin; the elastic member can make the positioning pin pop out in the direction away from the bottom plate, making the positioning shell operation easier. Specifically, when positioning the shell, all the positioning members must be inserted into the first positioning hole of the matching shell when the shell is suspended before the shell can be placed on the positioning plate. This operation is relatively complicated. The design of the positioning assembly allows the lifting plate to be raised to a height higher than the top of the positioning pin so that the reference surface of the shell covers the top of the positioning pin and then the shell is randomly moved. When the positioning pin is aligned with the second positioning hole of the shell, the elastic member causes the positioning pin to pop out and insert into the second positioning hole to preliminarily position the shell. Then, the lifting plate is lowered so that the positioning member is inserted into the first positioning hole of the shell to complete the positioning of the shell. This design makes the positioning shell operation easier.
[0009] Optionally, a limit block is provided on the locating pin, and the limit block is used to abut against the bottom surface of the lifting plate to limit the height of the locating pin passing through the top surface of the lifting plate.
[0010] By adopting the above technical solution, the limit block can limit the length of the positioning pin popping out of the top surface of the lifting plate to prevent the positioning pin from continuously extending out of the top surface of the lifting plate when the lifting plate descends until it abuts against the bottom of the second positioning hole of the shell and damages the second positioning hole.
[0011] Optionally, a pull rod is provided on the positioning pin, the pull rod is arranged on the side of the limit block away from the bottom plate and one end of the pull rod extends out of the side of the lifting plate, and the end of the positioning pin that passes through the lifting plate can be retracted into the lifting plate by moving the pull rod.
[0012] By adopting the above technical scheme, when a positioning pin is not compressed by the base surface of the shell due to an error during the operation of positioning the shell but pops out of the top surface of the lifting plate, the error can be corrected by moving the pull rod to make one end of the positioning pin that has passed through the top surface of the lifting plate retract into the lifting plate, and then readjusting the position of the shell. This design makes the correction operation after the wrong operation more convenient, thereby improving production efficiency; secondly, the design of the pull rod extending out of the side of the lifting plate can not only facilitate the movement of the pull rod, but also determine whether the positioning pin is fully inserted into the second positioning hole of the shell by observing the height of the pull rod.
[0013] Optionally, a steel wire rope is connected to the end of the pull rod away from the positioning pin, and a winding assembly is provided on the base plate at the end of the pull rod away from the positioning pin. The winding assembly includes a mounting frame arranged on the base plate and a winding roller rotatably connected to the mounting frame. The winding roller is located below the pull rod, and the steel wire rope is wound on the winding roller. The steel wire rope can be wound up by rotating the winding roller to pull the pull rod downward so that the end of the positioning pin that passes through the lifting plate is retracted into the lifting plate.
[0014] By adopting the above technical solution, multiple pull rods can be pulled down uniformly by rotating the reeling roller, so that when positioning the shell, if multiple positioning pins are not compressed by the shell reference surface but pop out of the top surface of the lifting plate, the multiple positioning pins can be quickly retracted from one end of the lifting plate into the lifting plate, and the shell position can be readjusted to correct the error. This design not only improves the convenience and production efficiency of the correction operation, but also makes the retraction operation of the positioning pins more accurate and controllable.
[0015] Optionally, a pawl for unidirectionally engaging the ratchet wheel is rotatably connected to the mounting frame, and when the winding roller rotates in the opposite direction of the winding wire rope, the pawl can engage the ratchet wheel to prevent the winding roller from rotating.
[0016] By adopting the above technical solution, when the position of the shell is adjusted after the winding roller is rotated to rewind the wire rope to retract the locating pin, the design of the ratchet and the pawl can prevent the winding roller from rotating in the opposite direction of the winding wire rope, thereby preventing the locating pin from rebounding; after adjusting the position of the shell, the pawl can be rotated to misalign it with the ratchet to release the locating pin and cause it to rebound; this design makes the retraction action of the locating pin more precise and controllable, and further improves the convenience of operating the positioning shell.
[0017] Optionally, the pressing assembly includes a second telescopic driving member arranged on the base plate and a pressing block used to clamp the shell in cooperation with the support member, the pressing block is rotatably connected to the second telescopic driving member, the output end of the second telescopic driving member is rotatably connected to one end of the pressing block, and the second telescopic driving member is used to drive the pressing block to press the shell down to lock the shell on the support member.
[0018] By adopting the above technical solution, after the shell is received by the support member and positioned by the positioning member, the pressing assembly can firmly lock the shell on the support member, effectively preventing displacement during part processing and ensuring the processing accuracy of the parts; specifically, by controlling the extension and retraction of the output end of the second telescopic drive member, the pressure block can be driven away from the output end of the second telescopic drive member to press down the shell or move away from the shell, making the operation of locking the shell on the support member simpler and faster.
[0019] Optionally, it also includes a guide assembly, which includes a guide pin arranged on the bottom surface of the lifting plate and a guide seat arranged on the base plate, and the end of the guide seat away from the base plate is provided with a first guide hole matching the size of the guide pin, and the end of the guide pin away from the lifting plate is slidably inserted into the first guide hole.
[0020] By adopting the above technical scheme, the design of the guide assembly can effectively prevent the lifting plate from tilting due to uneven force on the lifting plate caused by the irregular shape of the shell during the lifting process, thereby ensuring the stability and accuracy of the lifting plate during the lifting process, avoiding the problem of inaccurate shell positioning caused by the tilt of the lifting plate, and improving the operating accuracy and stability of the entire tooling; the coordinated use of the guide pin and the guide seat provides precise guidance for the lifting plate, ensuring the linear motion of the lifting plate during the lifting process.
[0021] Optionally, the top surface of the lifting plate is provided with a plurality of supporting blocks for supporting a reference surface of the shell body, and the supporting blocks are detachably connected to the lifting plate and the supporting height is adjustable.
[0022] By adopting the above technical solution, the design of the supporting block supporting the shell reference surface reduces the flatness accuracy requirement for the top surface of the lifting plate, thereby reducing the processing difficulty of the lifting plate; and the supporting block acts as a wearing part, which can be removed and replaced after long-term wear and tear, thereby reducing the maintenance cost of the tooling; the height of the supporting block is adjustable, so that the position accuracy between the supporting blocks can be quickly checked, thereby ensuring the accuracy of the shell processing.
[0023] Optionally, the lifting plate is provided with a chip dropping hole penetrating through the top surface and the bottom surface of the lifting plate.
[0024] By adopting the above technical solution, the setting of the chip removal hole facilitates the discharge of chips and coolant generated during the processing, keeps the lifting plate clean, reduces equipment failures caused by chip accumulation, and improves the service life and maintenance efficiency of the tooling.
[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The gearbox housing tooling significantly improves the convenience of disassembly and assembly during gearbox housing processing, and effectively prevents the collision between the housing and the support when hoisting the gearbox housing. Specifically, when installing the gearbox housing on the tooling, the lifting plate is raised to a height just above the top of the support, so that when the gearbox housing is hoisted, the top surface of the lifting plate can bear the tilted housing and allow the positioning member to be inserted into the first positioning hole of the housing to accurately position the housing, effectively preventing the gearbox housing from colliding with the support; after the gearbox housing is placed on the top surface of the lifting plate, the lifting plate is lowered to a height lower than the top of the support so that the housing can be stably supported by the support to reduce the shaking of the housing during processing; then, the pressing assembly presses down the housing and firmly locks the housing on the support to further prevent the movement of the housing during processing. When removing the gearbox housing from the tooling, the lifting plate is lifted to a height higher than the top of the positioning member to facilitate the lifting of the housing, preventing the housing from colliding with the support after the housing is tilted when lifting the gearbox housing, and solving the problem of the positioning member being engaged with the first positioning hole of the housing and affecting the removal of the housing; 2. By adopting the above technical solution, the positioning pin can quickly and preliminarily position the shell, simplifying the difficulty of the positioning member to position the shell; the positioning base can limit and guide the positioning pin to ensure the positioning accuracy of the positioning pin; the elastic member can make the positioning pin pop out in the direction away from the bottom plate, making the positioning shell operation easier. Specifically, when positioning the shell, all the positioning members must be inserted into the first positioning hole of the matching shell when the shell is suspended before the shell can be placed on the positioning plate. This operation is relatively complicated. The design of the positioning assembly allows the lifting plate to be raised to a height higher than the top of the positioning pin so that the reference surface of the shell covers the top of the positioning pin and then the shell is randomly moved. When the positioning pin is aligned with the second positioning hole of the shell, the elastic member causes the positioning pin to pop out and insert into the second positioning hole to preliminarily position the shell. Then, the lifting plate is lowered so that the positioning member is inserted into the first positioning hole of the shell to complete the positioning of the shell. This design makes the positioning shell operation easier.
[0026] 3. By adopting the above technical solution, when a positioning pin is not compressed by the base surface of the shell but pops out of the top surface of the lifting plate due to an error during the operation of positioning the shell, the error can be corrected by toggling the pull rod to make one end of the positioning pin that has passed through the top surface of the lifting plate retract into the lifting plate, and then readjusting the position of the shell. This design makes the correction operation after the wrong operation more convenient, thereby improving production efficiency; secondly, the design of the pull rod extending out of the side of the lifting plate can not only facilitate the toggling of the pull rod, but also determine whether the positioning pin of the positioning shell is inserted into the second positioning hole of the shell by observing the height of the pull rod.

It should be emphasized that the second positioning hole of the housing 100 is a blind hole. In other embodiments, the limit block 521 can also be a nut-like structure and is threadedly connected to the positioning pin 52 to adjust the length of the positioning pin 52 extending out of the top surface of the lifting plate 42.

The clamping end of the pawl 74 faces the side of the lifting plate 42 and the length of the pawl 74 is greater than the length from the bottom diameter of the ratchet 73 to the center of the rotating shaft of the pawl 74. When the winding roller 72 is rotated clockwise, the teeth of the ratchet wheel 73 can push the pawl 74 away to make it misaligned with the ratchet wheel 73, so as to ensure that the wire rope 10 can be smoothly wound up and the positioning pin 52 can be pulled down; when the winding roller 72 is rotated counterclockwise, the teeth of the ratchet wheel 73 and the pawl 74 are engaged to prevent the winding roller 72 from rotating so that the positioning pin cannot be popped out, and when the teeth of the ratchet wheel 73 and the pawl 74 are engaged, the pawl 74 can be manually rotated to make it misaligned with the ratchet wheel 73, and then the wire rope 10 can be released to make the positioning pin 52 pop out.
[0051] The advantages of Example 2 over Example 1 are as follows: the setting of the positioning assembly 5 improves the convenience of positioning the shell 100 and further improves the production efficiency; when positioning the shell 100, the top surface of the lifting plate 42 is raised to a height higher than the positioning pins 52 and the shell 100 is placed on the top surface of the lifting plate 42, so that the reference surface of the shell 100 covers all the positioning pins 52, and then the top surface of the lifting plate 42 is moved to a height higher than the positioning pins 52 but higher than the positioning member 3, and the shell 100 is randomly moved so that the positioning pins 52 are snapped into the second positioning hole of the shell 100 to complete the preliminary positioning of the shell 100; the elastic member The arrangement of 6 and the pull rod 522 can make the positioning pin 52 retract into the lifting plate 42 by moving the pull rod 522 when the positioning pin 52 is not compressed by the reference surface of the shell 100 due to an operational error and pops out from the top surface of the lifting plate 42, and it is also possible to judge whether the positioning pin 52 is inserted into the second positioning hole of the shell 100 by observing the height of the pull rod 522; the arrangement of the winding assembly 7 can pull down multiple pull rods 522 at one time, thereby improving the convenience of operation; the arrangement of the ratchet 73 and the pawl 74 can prevent the retraction of the positioning pin 52, and make the retraction operation of the positioning pin 52 precise and controllable, further improving the practicality of the tooling.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
