[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0035] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0036] The following describes, with reference to the accompanying drawings, some embodiments of a gear keyway machining device provided by this utility model. Example 1

[0037] Combination Figures 1-7As shown, the present invention provides a gear keyway machining device, including six sets of keyway mechanisms 300, a groove depth adjustment mechanism 200 supporting the six sets of keyway mechanisms 300, and a load-bearing linkage mechanism 100 disposed on the groove depth adjustment mechanism 200. The load-bearing linkage mechanism 100 is installed on the fixture of the keyway machine tool and provides adjustable support for the groove depth adjustment mechanism 200. The groove depth adjustment mechanism 200 is used to control the extension distance of the six sets of keyway mechanisms 300. The six sets of keyway mechanisms 300 are used for efficient keyway machining of gears or gear shafts.

[0038] The load-bearing linkage mechanism 100 includes a limiting housing 110, an annular pad 120 is provided at the bottom of the inner side of the limiting housing 110, multiple sets of bolts 130 are provided inside the annular pad 120, an annular slider 140 is provided at the top of the inner side of the limiting housing 110, multiple evenly distributed linkage teeth 150 are provided at the top of the annular slider 140, and evenly distributed drive teeth 160 are provided on the outer wall of the annular slider 140.

[0039] The groove depth adjustment mechanism 200 includes a pressure-resistant component 210 disposed at the bottom of the ring pad 120, a shaft 240 disposed within the pressure-resistant component 210, a vertical shaft 260 mounted on the top of the shaft 240, and a first beam plate 270 and a second beam plate movably mounted on the vertical shaft 260.

[0040] The keyway mechanism 300 includes a support plate 310 disposed on the threaded section, two bearings 320 disposed inside the support plate 310, and bushings 330 installed inside the two clamps 220.

[0041] One end of the bushing 330 is provided with a milling drill bit 360, and the other end of the bushing 330 is provided with a insertion rod 340;

[0042] A drive toothed roller 350 is provided on the outside of the insertion rod 340.

[0043] After the stop lever limiting housing 110 is fixed to the machine tool fixture by welding, the supported annular slider 140 can be clamped. As the external drive device runs and drives the toothed block 160 through chain transmission, the linkage toothed block 150 set on the top of the annular slider 140 can drive the six drive toothed rollers 350 at high speed. At this time, the bushing 330 clamped by the two bearings 320 can cooperate with the milling drill bit 360 to perform high-efficiency keyway treatment on the workpiece or toothed shaft.

[0044] When the size of the workpiece or gear shaft decreases or increases, only the hydraulic component 230 needs to be operated. The hydraulic sub-rods inside the hydraulic component 230 control the chuck 250, shaft 240 and vertical shaft 260. At this time, the multiple sets of first beam plates 270 and second beam plates can simultaneously control the six sets of keyway mechanisms 300 to perform equal-interval adjustment. Example 2

[0045] Combination Figures 3-5 As shown, based on Embodiment 1, the bottom of the ring pad 120 is provided with evenly distributed insertion holes, and the top end of the truss 211 is adapted to pass through the insertion holes.

[0046] The anti-compression component 210 includes a truss 211, with a slide rail inside the truss 211. A positioning rod 212 is installed at one end of the inner side of the slide rail, and a reinforcing spring 213 is provided inside the slide rail, with the reinforcing spring 213 located outside the positioning rod 212.

[0047] Preferably, after the end of the truss 211 is snapped into the socket, the end of the truss 211 needs to be fixed by bolts 130. At this time, the stable truss 211 can provide sufficient stable support for the first beam plate 270 and the second beam plate after extension, so as to ensure that the fixed keyway mechanism 300 will not vibrate during the adjustment period.

[0048] The other end of the reinforcing spring 213 is connected to a pad 214;

[0049] The arc-shaped groove at the outer end of the pad 214 fits and conforms to the shaft 240, and the shaft 240 has an overall I-shaped structure.

[0050] The top of the vertical shaft 260 is provided with a threaded section, and a nut is installed on the threaded section.

[0051] Preferably, when the pad 214 is compressed by the reinforcing spring 213, the shaft 240 and the vertical shaft 260 can regain kinetic energy after extension, and the first beam plate 270 and the second beam plate, which are constrained by the vertical shaft 260 and stacked, can remain stable during expansion and contraction. Example 3

[0052] Combination Figures 2-6 As shown, based on Embodiment 1, the groove depth adjustment mechanism 200 also includes multiple sets of adapters, two sets of clamps 220 set at the bottom of the truss 211, a hydraulic component 230 set in the two sets of clamps 220 and placed horizontally, and a chuck 250 set at the bottom end of the shaft 240.

[0053] The outer end of the hydraulic sub-rod inside the hydraulic component 230 is installed inside the chuck 250;

[0054] The adapter consists of two oval pads, two inserts, and two sleeves.

[0055] Preferably, there are six sets of adapters, and the adapters are used to assemble the ends of an adjacent first beam plate 270 and a second beam plate. When the six sets of keyway mechanisms 300 are extended in conjunction with the slot depth adjustment mechanism 200 to achieve spacing adjustment, the milling drill bit 360 installed in the bushing 330 can select different drill bits according to the type or width of the keyway of the workpiece or gear shaft.

[0056] The working principle and usage process of this utility model: The limiting shell 110 is pre-installed on the fixture of the keyway machine tool by welding. At this time, the orientation of the port of the load-bearing linkage mechanism 100 is set according to the state of workpiece delivery.

[0057] When the port of the limiting housing 110 is vertically upward, the workpiece needs to be vertically raised and lowered along the port of the limiting housing 110 in this way to perform keyway machining on the surface of the workpiece.

[0058] When the port of the limiting housing 110 faces the horizontal direction, the workpiece being delivered laterally can move laterally along the port of the limiting housing 110;

[0059] When the workpiece size is different, the hydraulic component 230 needs to be operated. As the hydraulic rod inside the hydraulic component 230 contracts, the chuck 250, shaft 240 and vertical shaft 260 installed at the outer end of the hydraulic rod will be compressed and pull multiple sets of first beam plates 270 and second beam plates to work together. At this time, the six sets of keyway mechanisms 300 can expand or contract at the same speed and at equal intervals. After the six sets of keyway mechanisms 300 are adjusted, the hydraulic component 230 can be stopped. At this time, an external drive device and a chain-driven ring slider 140 are needed. The external chain meshes with multiple evenly distributed drive tooth blocks 160. As the ring slider 140 rotates, the six circumferentially distributed drive tooth rollers 350 can be driven at high speed, so that the six milling drills 360 can perform efficient keyway processing on the surface of the workpiece.

[0060] At the same time, in addition to keying gears, the device can also perform synchronous keying on gear shafts.

[0061] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
