Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0029] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them.

[0032] The part is limited and fixed on the base, and then the rotation of the output end of motor 2 drives the milling cutter to rotate, and then the rotation of the output end of motor 1 drives the screw rod to rotate, and the rotation of the screw rod drives the motor 2 on the adjusting frame to move, thereby the milling cutter moves and rotates at the same time to process the keyway of the part.
[0033] In the related art, the keyway processing device is not convenient for limiting and fixing parts of different sizes. Generally, several electric push rods are used to drive the clamping plates to limit and fix parts of different sizes. However, when the keyway of a part is processed, sometimes multiple keyways are arranged equidistantly along the circumferential direction as needed, so that the parts need to be frequently loaded and unloaded to adjust the processing angle, which affects the work efficiency and has poor processing accuracy.
[0034] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a keyway processing device. When the part needs to be limited and fixed and the angle needs to be adjusted, the part only needs to be placed on the surface center of the workbench 25, and then the output ends of several electric push rods 27 drive several clamping plates 28 to move and limit the part, thereby facilitating the limit fixation of parts of different sizes. When the angle of the keyway processed part needs to be adjusted, the output end of the motor 3 23 is rotated to drive the worm 24 on the arch plate 22 to rotate, and the rotation of the worm 24 drives the worm wheel 26 to rotate, and the rotation of the worm wheel 26 drives the workbench 25 to rotate on the surface of the fixed plate 21, thereby facilitating the adjustment of the angle of the keyway processing of the part.
[0035] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0036] Combination Figure 1-Figure 4The embodiment of the present application provides a keyway processing device, including a main body component 1; the main body component 1 includes: a base 11, on which a connecting column 12 is arranged; a motor 13, which is arranged on the connecting column 12; a screw rod 14, which is arranged on the output end of the motor 13, and the screw rod 14 and the connecting column 12 are rotatably connected; an adjustment frame 15, which is threadedly connected to the screw rod 14; a motor 2 16, which is arranged on the adjustment frame 15; a milling cutter 17, which is arranged on the output end of the motor 2 16; the base 11 is provided with an adjustment Component 2, the adjustment component 2 includes: a fixed plate 21, which is arranged on the base 11; an arched plate 22, which is arranged on the fixed plate 21; a motor three 23, which is arranged on the arched plate 22; a worm 24, which is arranged on the output end of the motor three 23; a workbench 25, which is rotatably connected to the fixed plate 21; a worm wheel 26, which is arranged on the workbench 25, and the worm wheel 26 and the worm 24 are meshed; an electric push rod 27, which is arranged on the workbench 25; and a clamping plate 28, which is arranged on the output end of the electric push rod 27.
[0037] The part is limited and fixed on the base 11, and then the rotation of the output end of the motor 2 16 drives the rotation of the milling cutter 17, and then the rotation of the output end of the motor 1 13 drives the rotation of the screw rod 14, and the rotation of the screw rod 14 drives the motor 2 16 on the adjusting frame 15 to move, thereby the part keyway is processed by the milling cutter 17 while moving and rotating, but the existing keyway processing device is inconvenient for limiting and fixing parts of different sizes and adjusting the angle, so when the part needs to be limited and fixed and the angle needs to be adjusted, it is only necessary to place the part at the center of the surface of the workbench 25, and then drive the output ends of several electric push rods 27 to drive several clamping plates 28 to move and limit the part, thereby facilitating the limit and fixation of parts of different sizes, and when the angle of the keyway processing part needs to be adjusted, the rotation of the output end of the motor 3 23 drives the worm 24 on the arch plate 22 to rotate, the rotation of the worm 24 drives the worm wheel 26 to rotate, and the rotation of the worm wheel 26 drives the workbench 25 to rotate on the surface of the fixed plate 21, thereby facilitating the adjustment of the angle of the part keyway processing.
[0038] In some embodiments, the adjustment assembly 2 further includes: a protective pad 29, which is disposed on the clamping plate 28. When a plurality of clamping plates 28 are moved to squeeze and limit a part, the protective pad 29 can prevent the clamping plate 28 from directly squeezing the part and causing damage to it.
[0039] In some embodiments, a disassembly component 3 is provided on the base 11, and the disassembly component 3 includes: a groove 31, which is opened on the base 11, and the fixed plate 21 is inserted into the groove 31; a sliding bar 32, which is arranged on the fixed plate 21; a slide groove 33, which is opened in the groove 31, and the sliding bar 32 is inserted into the slide groove 33; an insertion rod 34, which is slidably connected to the base 11; a spring 35, which is sleeved on the insertion rod 34, and the two ends of the spring 35 are respectively fixedly connected to the insertion rod 34 and the base 11; a fixing hole 36, which is opened on the fixed plate 21, and the insertion rod 34 is inserted into the fixing hole 36.
[0040] When the fixing plate 21 needs to be installed, the spring 35 is stretched to a certain position by pulling the insertion rod 34, and then the two sliding bars 32 on the lower surface of the fixing plate 21 are aligned with the two sliding grooves 33 and moved to place the fixing plate 21 in the groove 31. When the fixing plate 21 is in place, the insertion rod 34 is released by the resilience of the spring 35 and inserted into the fixing hole 36 for fixing. When the fixing plate 21 needs to be removed, the fixing is released by moving the insertion rod 34 out of the fixing hole 36, and finally the fixing plate 21 is moved outward and taken out, thereby facilitating the disassembly of the adjustment assembly 2 for later maintenance.
[0041] In some embodiments, the disassembly assembly 3 also includes: a guide block 37, which is arranged on the insertion rod 34. When the fixing plate 21 is placed in place and the insertion rod 34 is moved and inserted into the fixing hole 36 for fixing, because the guide block 37 is conical, it is convenient for the insertion rod 34 to be quickly and accurately inserted into the fixing hole 36.
[0042] In some embodiments, the disassembly component 3 also includes: a hook 38, which is arranged on the base 11. During the disassembly and assembly of the fixing plate 21, the insertion rod 34 is temporarily fixed by pulling the pull ring on the insertion rod 34 and buckling it onto the hook 38, thereby avoiding the need to pull the insertion rod 34 all the time during the disassembly and assembly process.
[0043] In some embodiments, a handle 4 is provided on one side of the fixing plate 21. When the fixing plate 21 needs to be moved outward, the fixing plate 21 can be moved outward by pulling the handle 4, which is convenient and labor-saving to operate.
[0044] In some embodiments, a mounting base 5 is provided between the workbench 25 and the electric push rod 27. When the electric push rod 27 needs to be fixed on the workbench 25 for use, the electric push rod 27 is fixed by the mounting base 5 in conjunction with bolts, so that the electric push rod 27 is easy to install, fix and disassemble.
[0045] In some embodiments, the sliding bar 32 is in a “T” shape, so that the fixing plate 21 is stably placed in the groove 31 to avoid up and down movement.
[0046] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.
[0047] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
[0048] 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.
