DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, an automatic gear grinding machine for producing carbide band saw blades includes a bottom plate 1, characterized in that: a mounting plate 2 is fixedly connected to one side of the top outer wall of the bottom plate 1, an adjusting assembly 7 is installed on the top of the mounting plate 2, the adjusting assembly 7 includes a limiting groove 701 opened on the top outer wall of the mounting plate 2, a driving ring 703 is slidably connected in the limiting groove 701, a screw rod 702 is threadedly connected in the driving ring 703, and both ends of the screw rod 702 are rotatably connected to the inner walls of both sides of the limiting groove 701, and the outer walls of both ends of the top outer wall of the mounting plate 2 are rotatably connected to symmetrically arranged mounting platforms 704, and one side of the bottom outer wall of the two mounting platforms 704 is fixedly connected to an extension column 705, and the two extension columns 705 are slidably connected in the driving ring 703, and the top outer walls of the two mounting platforms 704 are fixedly installed with grinders 3, and the grinding heads of the two grinders 3 are both arranged toward the mounting frame 5. .

[0024] The grinding head of one of the grinders 3 is brought into contact with the teeth of the band saw blade, and then the angle of the grinding head is changed by adjusting the component 7 so that it can completely fit the teeth. The turntable on one side of the mounting plate 2 is rotated, and the turntable drives the screw rod 702 to rotate in the limiting groove 701. The driving ring 703 sliding in the limiting groove 701 will translate to one side driven by the screw rod 702. The driving ring 703 can drive the mounting table 704 to rotate on the top of the mounting plate 2 through the extension column 705, and then the angle of the grinder 3 will also change accordingly. The grinder 3 is started to start grinding, and one side of one of the teeth and the other side of the other tooth on the band saw blade will be grinded.

[0025] like Figure 2 and Figure 4 As shown, electric telescopic rods 4 are fixedly installed at both ends of the top outer wall of the base plate 1, and the tops of the two electric telescopic rods 4 are fixedly connected to the same mounting frame 5, and two groups of transmission wheels 6 are installed inside the mounting frame 5, and one group of transmission wheels 6 is composed of a plurality of transmission wheels 6 distributed at equal distances, and a transmission component 8 is installed on the outer wall of one side of the mounting frame 5, and the transmission component 8 includes a mounting rod 803 fixedly connected to the top outer wall of the base plate 1, and one end of the top of the mounting rod 803 is rotatably connected to a limiting rod 804 through a hinge, and two gears 801 are rotatably connected to the middle position of the outer wall of one side of the mounting frame 5, and the two gears 801 are coaxially fixed with the two transmission wheels 6 respectively, and a plurality of convex rods 802 distributed at equal distances are fixedly connected to the outer wall of one side of a gear 801 at the bottom, and the plurality of convex rods 802 can all be adapted to the limiting rod 804.

[0026] The electric telescopic rod 4 drives the mounting frame 5 to rise, and the saw blade no longer contacts the grinding head. One of the protruding rods 802 first contacts the outer wall of one side of the limiting rod 804, and the limiting rod 804 will flip upward without changing the position of the protruding rod 802. The electric telescopic rod 4 retracts, and the protruding rod 802 contacts the top surface of the limiting rod 804. Since the limiting rod 804 is restricted by the mounting rod 803 and cannot flip, the protruding rod 802 can be driven to move upward, and the gear 801 connected thereto will be driven to rotate. This gear 801 drives another gear 801 to rotate through meshing, and the two driving wheels 6 inside the mounting frame 5 are driven to rotate synchronously, the position of the saw blade will change, and the grinder 3 will process new saw teeth, and the grinding work can be completed by reciprocating.

The two protrusions are respectively slidably connected in the two limiting grooves 706, which can further increase the stability of the driving ring 703 and thereby ensure that the position of the grinder 3 will not change.

[0028] like Figure 1 and Figure 3 As shown, the lead angle of the thread of the screw rod 702 is smaller than the equivalent friction angle, so that it has self-locking properties, so that the position of the drive ring 703 will not change due to external forces.

[0029] The utility model provides an automatic gear grinding machine for producing carbide band saw blades, and the specific working principle is as follows:

[0030] When the device is working, the band saw blade to be grinded is first squeezed between the upper and lower sets of transmission wheels 6, and the grinding head of one of the grinders 3 is made to contact the saw teeth of the band saw blade. Then, the angle of the grinding head is changed by adjusting the component 7 so that it can completely fit the saw teeth. The turntable on one side of the mounting plate 2 is rotated, and the turntable drives the screw rod 702 to rotate in the limiting groove 701. The driving ring 703 sliding in the limiting groove 701 will translate to one side under the drive of the screw rod 702. The driving ring 703 can drive the mounting table 704 to rotate on the top of the mounting plate 2 through the extension column 705, and then the angle of the grinder 3 will also change accordingly. Then, the grinder 3 is started to start grinding. One side of one of the saw teeth on the band saw blade and the other side of the other saw tooth will be grinded. Then The electric telescopic rod 4 on the top of the base plate 1 is started, and the electric telescopic rod 4 drives the mounting frame 5 to rise, and the saw blade no longer contacts the grinding head. One of the protruding rods 802 first contacts the outer wall of one side of the limiting rod 804, and the limiting rod 804 will flip upward without changing the position of the protruding rod 802. The electric telescopic rod 4 retracts, and the protruding rod 802 contacts the top surface of the limiting rod 804. Since the limiting rod 804 is restricted by the mounting rod 803 and cannot flip, the protruding rod 802 can be driven to move upward, and the gear 801 connected thereto will be driven to rotate. This gear 801 drives another gear 801 to rotate through meshing, and the two driving wheels 6 inside the mounting frame 5 are driven to rotate synchronously, the position of the saw blade will change, and the grinder 3 will process new saw teeth, and the grinding work can be completed by reciprocating.
