Problems solved by technology

The disadvantages of this method are as follows: ①, the upper generatrix of the grinding wheel 74 is trimmed, due to the accumulated error of the Y' axis and the axis of the grinding wheel spindle (that is, the Y' axis and the Y axis have an included angle, the axis of the grinding wheel spindle and the Y axis There will be an included angle), which will cause the lower generatrix of the grinding wheel 74 (the generatrix below the axis of the grinding wheel 74) to be non-parallel to the Y axis after sand repair, so that when the grinding wheel is processing the workpiece, the grinding plane on the workpiece will be uneven, and steps will easily appear Phenomenon; ②, the head structure of the grinding machine main shaft is complicated, adding parts such as the support 71 and the sliding block 72 above the grinding wheel cover 73, the cost is high, and the failure rate is high; ③, the Z-axis burden of the grinding machine is increased; ④, Only the grinding wheel 74 (that is, the horizontal grinding wheel) with the central axis set horizontally can be automatically repaired, but the grinding wheel 74 (that is, the vertical grinding wheel) that is set vertically with the central axis cannot be automatically repaired

Embodiment 1

[0031] Such as Figure 2~Figure 6 As shown, a grinding machine capable of automatically dressing grinding wheels includes a frame 1 on which a crossbeam 2 and a worktable 10 capable of moving forward and backward are horizontally installed (hereinafter referred to as the moving direction as the X axis), and the crossbeam 2 is movably connected with a slide block 3 that can slide left and right on the beam 2, and a grinding wheel mount 30 that can move up and down is installed on the slide block 3. Wherein, the grinding wheel mounting seat 30 can be driven by the power mechanism to move up and down, or the beam 2 can move up and down to drive it to move up and down, and the present embodiment is preferably the former kind of movement. A grinding wheel 41 is mounted on the grinding wheel mount 30 . Preferably, the slider 3 includes a first slider 31 and a second slider 32 , and the first slider 31 can slide left and right on the beam 2 (hereinafter referred to as the moving dir...

Embodiment 2

[0036] Such as Figure 7~Figure 8 As shown, the difference from Embodiment 1 is that the dressing pen mounting seat 5 includes a first mounting seat 501 disposed below the first grinding wheel 411 and a second mounting seat 502 disposed below the second grinding wheel 412 , both the first mounting base 501 and the second mounting base 502 are installed on the frame 1 . Two grinding wheel dressing pens 50 are installed on the first mounting base 501, one of which is set vertically and the other is set horizontally. A grinding wheel dressing pen 50 is installed on the second mounting base 502, and the grinding wheel dressing pen 50 is vertically arranged.

[0037] In addition, the present invention also relates to a sand repairing method for a grinding machine, the steps of which are as follows:

[0038] ①. Set the mechanical origin on the grinding machine, the front and back direction is the X axis, the left and right direction is the Y axis, and the up and down direction is ...

Abstract

The invention discloses a grinding machine capable of automatically dressing a grinding wheel and a grinding wheel dressing method of the grinding machine. The grinding machine comprises a machine frame which is horizontally provided with a transverse beam and a workbench capable of moving back and forth, the transverse beam is connected with a sliding block capable of sliding leftwards and rightwards on the transverse beam, the sliding block is provided with a grinding wheel installation base capable of moving vertically, the grinding wheel installation base is provided with the grinding wheel used for machining a workpiece, the machine frame is provided with a grinding wheel dresser comprising a dressing pen installation base arranged on the machine frame, and the dressing pen installation base is fixedly provided with a dressing pen located within the route range of the grinding wheel and capable of dressing the grinding wheel when the grinding wheel rotates and moves. The grinding machine uses six-axis numerical control, achieves complete and automatic grinding wheel dressing in various modes, can achieve full-automation batch intervention-free production except for clamping the workpiece, is high in production efficiency, and can effectively reduce labor intensity of workers.

Description

technical field [0001] The invention relates to the field of grinding machines, in particular to a grinding machine capable of automatically dressing grinding wheels and a sand repairing method thereof. Background technique [0002] Grinding machine is a processing equipment often used in industrial production. There is a grinding wheel installed on the grinding machine. The grinding wheel will wear out during use, which will affect the accuracy of the product processed by the grinding machine. Therefore, it is necessary to dress the grinding wheel to make the grinding wheel The accuracy meets the requirements of use. [0003] figure 1 Shows the way of dressing a conventional grinder. The traveling direction of the grinding wheel on the grinding machine is called the Y axis, and the vertical direction on the grinding machine is called the Z axis. The fuselage 7 of the grinding machine is provided with a support 71, and a slide block 72 that can move left and right on the ...
