Description

Technical Field

[0001] This utility model relates to the field of CNC gear hobbing machine technology, and in particular to a center mounting mechanism for a CNC gear hobbing machine. Background Technology

[0002] CNC gear hobbing machines are high-precision automated machining equipment mainly used for gear production. The center structure is one of the main components of a CNC gear hobbing machine, used to clamp and fix a cylindrical object. However, existing center structures are installed to the CNC gear hobbing machine via screws and threaded holes. For example, in a CNC gear hobbing machine center mounting structure as described in Chinese patent application number CN202420037968.0, a mounting post is located near the center of the top of the mounting plate, and a fixed plate is mounted on the top of the mounting post. A threaded hole is located near the center of the top surface of the fixed plate, and a threaded post is movably screwed into the threaded hole. A center rod is mounted on the top of the threaded post. A tapered post is mounted near the outer side of the threaded hole on the top of the fixed plate, and four sets of mounting holes are located on the top surface of the tapered post. The interiors of these four sets of mounting holes are movably mounted to corresponding mounting plates via corresponding mounting bolts. Fixed plates are mounted on both sides of each of the two sets of mounting plates, and the corresponding two sets of fixed plates are movably screwed to corresponding fixing bolts.

[0003] However, when using the mounting plate to clamp and fix the tip rod, since the surface of the mounting plate is smooth, it can only clamp and fix the tip rod, but cannot restrict the rotation of the tip rod. Therefore, when the tip structure shakes, the threaded post at the bottom of the tip rod may loosen from the threaded hole, or even fall off. Utility Model Content

[0004] To address the problem mentioned in the background art that, due to the smooth surface of the mounting plate, only the tip rod can be clamped and fixed, but the rotation of the tip rod cannot be restricted, and therefore, when the tip structure shakes, the threaded post at the bottom of the tip rod may loosen from the threaded hole or even fall off, this utility model provides the following technical solution:

[0005] A center mounting mechanism for a CNC gear hobbing machine includes a base, a center rod for placing a cylinder is provided at the top of the base, and a fixing device for fixing the center rod is provided at the top of the base.

[0006] The fixing device includes a mounting box fixedly installed on the top of the base, and the top rod passes through the box body. The mounting box is provided with a fixing component for fixing the top rod, and there are two fixing components. The mounting box is also provided with a driving component for driving the two fixing components to move in opposite directions and locking the top rod.

[0007] Furthermore, the base is provided with a rotating disk for rotation, and a support seat for supporting the top rod is fixedly installed on the top of the rotating disk.

[0008] Furthermore, the rod body of the tip rod is provided with an annular groove for engaging with the fixing component to lock the tip rod in place, and the bottom end of the tip rod is fixedly installed with a threaded post for threaded connection with the support seat.

[0009] Furthermore, the bottom of the annular groove is provided with a fixing groove for locking the top rod in conjunction with the fixing component, and there are four fixing grooves, which are arranged in a circumferential array within the fixing groove.

[0010] Furthermore, the drive assembly includes a screw disposed within the mounting box for driving two fixed components to move in opposite directions, and a slide bar is provided on the front side of the screw for allowing the fixed components to move left and right.

[0011] Furthermore, a handwheel for driving the screw to rotate is fixedly installed at the right end of the screw, and a locking rod for locking the handwheel is provided on the wheel body.

[0012] Furthermore, the fixing assembly includes a retaining plate threadedly connected to the screw for engaging within the annular groove, and a locking rod 2 for inserting into the fixing groove is fixedly mounted at one end of the retaining plate near the tip rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting a center rod and a fixing device, when it is necessary to install the center rod on the top of the support base, the threaded connection between the threaded column and the threaded hole can be used to install the center rod on the top of the support base. Then, by driving the screw to rotate by the handwheel, the clamping plate located at the two threads on the screw moves in opposite directions along the screw, so that the clamping plate is locked in the annular groove. At the same time, the locking rod can be inserted into the fixing groove, which can restrict the rotation of the center rod. Therefore, when the center rod shakes, it will prevent the threaded column at the bottom of the center rod from loosening from the threaded hole, thus avoiding the center rod from falling off.

[0023] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0024] Please see Figures 1-4 This utility model provides a center mounting mechanism for a CNC gear hobbing machine.

[0025] It includes a base 100, a top rod 200 for placing a cylinder is provided at the top of the base 100, and a fixing device 300 for fixing the top rod 200 is provided at the top of the base 100.

[0026] The base 100 is equipped with a rotating disk 101 for rotation, and the bottom end of the rotating disk 101 is connected to an external motor so that the rotating disk 101 can be rotated by the operation of the motor, so that the cylinder fitted on the tip rod 200 on the rotating disk 101 can rotate synchronously to perform gear processing on the cylinder. The top end of the rotating disk 101 is fixedly installed with a support seat 102 for supporting the tip rod 200, and the support seat 102 is connected to the rotating disk 101 by a settling bolt, so that the support seat 102 can be fixed on the rotating disk 101. The top center of the support seat 102 has a threaded hole for threaded connection with the tip rod 200.

[0027] The tip rod 200 has an annular groove 202 for engaging with the fixing component 330 to lock the tip rod 200 in place. A threaded post 201 for threaded connection with the support base 102 is fixedly installed at the bottom of the tip rod 200, and the threaded post 201 is welded to the bottom of the tip rod 200. The bottom of the annular groove 202 has four fixing grooves 203 for engaging with the fixing component 330 to lock the tip rod 200 in place. These four fixing grooves 203 are arranged in a circumferential array within the fixing grooves 203. Therefore, when the tip rod 200 needs to be installed on the top of the support base 102, the threaded connection between the threaded post 201 and the threaded hole allows the tip rod 200 to be installed on the top of the support base 102, and the fixing device 300 is used to fix the tip rod 200 to prevent it from loosening and falling off during shaking.

[0028] The fixing device 300 includes a mounting box 310 fixedly installed on the top of the base 100, and the fixing box 310 is welded to the top of the support base 102. The top rod 200 passes through the box body of the mounting box 310. The mounting box 310 is provided with a fixing component 330 for fixing the top rod 200. There are two fixing components 330 to facilitate fixing the top rod 200 by using the two fixing components 330 to be locked in the annular groove 202. The mounting box 310 is provided with a drive component 320 for driving the two fixing components 330 to move in opposite directions and locking the top rod 200.

[0029] The drive assembly 320 includes a screw 323 disposed within the mounting box 310 for driving two fixed assemblies 330 to move in opposite directions. The screw 323 has two symmetrically arranged threads on its shaft, with the threads turning in opposite directions to facilitate the two fixed assemblies 330 located at the two threads to move in opposite directions. At the same time, the left and right ends of the screw 323 are connected to the housing of the mounting box 310 through bearings to facilitate the rotation of the screw 323. A slide rod 324 is provided on the front side of the screw 323 for allowing the fixed assemblies 330 to move left and right.

[0030] A handwheel 321 for driving the screw 323 to rotate is fixedly installed on the right end of the screw 323. A locking rod 322 for locking the handwheel 321 is provided on the wheel body of the handwheel 321. The locking rod 322 passes through the wheel body of the handwheel 321 and is threadedly connected to the housing of the mounting box 310, so that the handwheel 321 can be locked.

[0031] The fixing assembly 330 includes a retaining plate 331 threadedly connected to the screw 323 for engaging within the annular groove 202, and the shape and size of the retaining plate 331 are identical to those of the annular groove 202. A locking rod 332 for insertion into the fixing groove 203 is fixedly mounted on one end of the retaining plate 331 near the tip rod 200. Therefore, when it is necessary to install the tip rod 200 on the top of the support base 102, the threaded connection between the threaded post 201 and the threaded hole can be used to install the tip rod 200 onto the support base 102. At the top of 02, the handwheel 321 drives the screw 323 to rotate, and the clamping plate 331 located at the two threads on the screw 323 moves in the opposite direction along the screw 323, so that the clamping plate 331 is locked in the annular groove 202. At the same time, the locking rod 232 can be inserted into the fixing groove 203, which can restrict the rotation of the top rod. Therefore, when the top rod 200 shakes, it will prevent the threaded post 201 at the bottom of the top rod 200 from loosening from the threaded hole, thus preventing the top rod 200 from falling off.

[0032] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
