DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described in detail below through the accompanying drawings and embodiments.

[0018] like Figure 1-4As shown, the utility model provides a horizontal grinding device installed on a vertical lathe, including a box body 1, a spindle sleeve 2, an electric spindle 3 and a grinding wheel clamping plate 4. The box body 1 is sleeved on the lower end of the ram 5 of the vertical lathe, the ram 5 is installed on the crossbeam 8 of the vertical lathe, and can be moved up and down on the crossbeam 8. The spindle sleeve 2 is fixedly connected to the lower end of the box body 1, and the electric spindle 3 is installed in the spindle sleeve 2; the output shaft of the electric spindle 3 is horizontal and perpendicular to the translation direction of the ram 5, and the output shaft end of the electric spindle 3 is installed with a grinding wheel clamping plate 4, and the grinding wheel 9 is installed on the grinding wheel clamping plate 4. In one embodiment of the utility model, the box body 1 and the spindle sleeve 2 are connected by welding. In order to ensure the connection strength, a connecting piece 12 is also used, and the connecting piece 12 is equivalent to a reinforcing rib plate; the spindle sleeve 2 and the electric spindle 3 are both existing technologies, and the assembly structure of the electric spindle 3 and the spindle sleeve 2 also belongs to the existing technology, which will not be repeated.

[0019] The box body 1 as a whole is a rectangular box-type structure with an opening at the top, and the upper surface of its bottom wall is provided with a T-shaped slide groove 111 and a positioning groove 112 perpendicular to the axial direction of the electric spindle 3, and the distance between the front wall and the rear wall of the box body 1 is greater than the thickness of the slide 5; the front wall of the box body 1 is distributed with a threaded front top screw 13, and the rear wall of the box body 1 is distributed with a threaded rear top screw 14, the front top screw 13 presses the front end surface of the slide 5 tightly, and the rear top screw 14 presses the rear end surface of the slide 5 tightly. When the position needs to be adjusted forward, the front top screw 13 can be loosened first, and then the rear top screw 14 can be tightened; when the position needs to be adjusted backward, the rear top screw 14 can be loosened first, and then the front top screw 13 can be tightened; in one embodiment of the utility model, the adjustment distance of the grinding wheel stroke forward and backward is 10mm, so the front top screw 13 and the rear top screw 14 are both designed as stepped shafts, and the corresponding mounting threaded holes are designed as stepped holes.
