Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses gear shaping machine suitable for processing long shaft type toothed parts. Referring to fig. 1, the gear shaper includes a base 100 and a gear shaper body 300, and a clamping structure is rotatably coupled to the base 100. The clamping arrangement comprises a three-jaw chuck 101, the three-jaw chuck 101 being used for fixing a workpiece. The base 100 is fixedly connected with a motor 102, and a spindle of the motor 102 is coaxially and fixedly connected with the three-jaw chuck 101. The motor 102 and the driving table 101 rotate, so as to drive the workpiece to rotate. The base 100 is fixedly connected with a cushion block 301 through a bolt. The gear shaper body 300 is located above the cushion block 301, the cushion block 301 is used for heightening the gear shaper body 300, and the distance between the gear shaper body 300 and the base 100 is increased, so that a workpiece with a long axial length can be machined (in the embodiment of the application, the workpiece with the long axial length is longer in length of the workpiece, but not in length of teeth on the workpiece), and the machining range of the gear shaper for long-shaft workpieces is widened.

Referring to fig. 2, a containing cavity 303 is formed in the cushion block 301, two guide rods 302 are vertically and fixedly connected to the base 100, and the guide rods 302 penetrate through the containing cavity 303 and penetrate through the gear shaping machine body 300. The guide bar 302 is slidably connected to the gear shaper body 300. The base 100 mounts an adjustment assembly 200 for adjusting the height of the gear shaper body 300. The height of the gear shaper body 300 relative to the base 100 is further adjusted by the adjustment assembly 200 to accommodate machining of long-axis workpieces of different lengths.

Referring to fig. 2, the adjustment assembly 200 includes a lead screw 201 and a nut 203. Lead screw 201 has two and is vertical setting, its lower extreme and base 100 fixed connection, and lead screw 201 is located one side that cushion 301 deviates from clamping structure. Each lead screw 201 is sleeved with a nut 203. The lead screw 201 is in threaded connection with the nut 203. The nut 203 abuts against the lower end face of the gear shaper body 300. When the nut 203 rotates relative to the lead screw 201, the nut 203 moves along the vertical direction of the lead screw 201, so that the gear shaper body 300 is driven to move in the vertical direction, and the height of the gear shaper body 300 is adjusted.

Referring to fig. 3, the nut 203 includes a contact ring 204 and a threaded ring 205. The contact ring 204 is sleeved on the screw 201, and the upper end thereof contacts the lower end face of the gear shaper body 300. The lower end of the contact ring 204 is coaxially provided with a circular receiving groove 206. The threaded ring 205 is disposed in the receiving groove 206 so as to be coaxial with the interference ring 204. The contact ring 204 and the threaded ring 205 are rotatably connected by a mounting thrust bearing 213. The threaded ring 205 is sleeved on the lead screw 201 and is in threaded connection with the lead screw 201. Rotating the threaded ring 205 may control the gear shaper body 300 to slide up and down. The thrust bearing 213 serves to reduce the friction between the abutment ring 204 and the threaded ring 205, facilitating the rotation of the threaded ring 205 even more.

Referring to fig. 3, the threaded ring 205 is coaxially sleeved with a worm wheel 207, and the worm wheel 207 is coaxially and fixedly connected with the threaded ring 205. The side wall of the contact ring 204 is rotatably connected with a worm 208, and the worm 208 is perpendicular to the axis of the worm wheel 207 and the middle section of the worm is located in the receiving groove 206. The worm 208 is engaged with the worm wheel 207 at a portion thereof located in the receiving groove 206. When the worm 208 rotates, the worm wheel 207 engaged with the worm 208 rotates, so that the threaded ring 205 rotates, and the worm 208 can rotate the threaded ring 205 more laborsavingly through the worm wheel 207, so that the height of the gear shaper body 300 can be adjusted more laborsavingly.

Referring to fig. 4, the worm screws 208 of the two nuts 203 are coaxially and fixedly connected through a connecting shaft 209, and the connecting shaft 209 is a single throw crankshaft. The connecting rod neck of the single-throw crankshaft is sleeved with a first connecting rod 210, the first connecting rod 210 is hinged with a second connecting rod 211, and the hinge axes of the first connecting rod and the second connecting rod are parallel to the axis of the connecting rod neck of the single-throw crankshaft. The lower end face of the gear shaping machine body 300 is fixedly connected with a connecting plate 304 which is vertically arranged. The end of the second link 211 facing away from the first link 210 passes through the connecting plate 304 and is slidably connected thereto. Two nuts 212 are threadedly connected to an end of the second link 211 facing away from the first link 210. The two nuts 212 are respectively located on two opposite sides of the connecting plate 304. The crank portion of the connecting shaft 209 is manually pushed, thereby rotating the connecting shaft 209. The connecting shaft 209 rotates to drive the two worms 208 to rotate simultaneously, so that the two worms 208 rotate simultaneously, the two nuts 203 rotate at the same angle, the vertical displacement of the nuts 203 is the same, and the stress pressure of the two lead screws 201 is the same. After the height adjustment of the gear shaper body 300 is completed, the nuts 212 are rotated to make the two nuts 212 respectively abut against the two opposite sides of the connecting plate 304, so that the rotation angle of the connecting shaft 209 is limited.

The implementation principle of the gear shaping machine suitable for processing the long shaft toothed piece is as follows: the cushion block 301 is utilized to heighten the gear shaper body 300, and the height distance between the gear shaper body 300 and the base 100 is increased, so that a workpiece with a longer axial length can be machined, and the machining range of the gear shaper for long-shaft workpieces is expanded.

When the height of the gear shaper body 300 needs to be further increased, the nut 212 is unscrewed. Then, the crank portion of the connecting shaft 209 is manually pushed, thereby rotating the connecting shaft 209. The rotation of the connecting shaft 209 simultaneously rotates the two worms 208, thereby simultaneously rotating the two worms 208. The worm gear 207 carries a ring of nuts 212 fixedly connected thereto. Because the ring of nuts 212 is coupled to the nut 212 of the lead screw 201, when the ring of nuts 212 rotates, it moves vertically along the lead screw 201, and the ring of nuts 212 pushes the gear shaper body 300 upward by the abutment ring 204.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
