Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, and more specifically to a lateral positioning and moving mechanism of a center frame for a roll grinder. Background Art

[0002] Roller grinder is a metal cutting machine tool, which consists of a bed, headstock, tailstock, center frame, longitudinal and transverse slides, grinding head, measuring frame and electrical numerical control system. It is divided into five subsystems: bearing system, drive system, grinding system, measuring system and control system. The workpiece is supported by the headstock, tailstock and bracket, and is driven to rotate by the headstock; the numerical control system controls the machine tool to perform multi-axis compound motion according to the mathematical model of the generatrix of the roll surface, and realizes the grinding of the roll surface metal by the grinding wheel during the motion; the online measurement system feeds back the measurement data to the grinder control system in real time, and the control system performs closed-loop control of the machine tool, thereby completing the precision machining of the workpiece. Due to the different sizes of rolls.

[0003] When the grinder is working, the center frame needs to be moved to adapt to rollers of various sizes. The center frame is placed on the guide rail of the grinder. Gears are arranged inside the center frame, and gear shafts are arranged on the gears. Usually, the center frame is moved by manual wrenches, which is not very stable, time-consuming, labor-intensive, and inconvenient to use.

[0004] After searching, a Chinese patent with authorization announcement number CN218169703U discloses a quick-moving device for the center frame of a CNC roller grinder. This structure is simple and convenient to use, and the accuracy of the threaded transmission position adjustment is high by slidably setting the center frame body on a mounting base and directly threading the center frame body through a screw arranged on the mounting base. In addition, two relatively arranged screw tubes are arranged on the screw thread sleeve. According to usage requirements, the screw tubes can rotate and simultaneously cling to both sides of the center frame body, further positioning the center frame body to prevent the center frame body from slipping and improve stability.

[0005] However, when this structure is actually used, when the center frame performs threaded guidance on the outside of the screw and the sliding rod, long-term use can easily cause wear on the outside of the screw and the sliding rod, and it is difficult to lubricate and maintain the outside of the screw and the sliding rod, affecting use. In view of this, the utility model proposes a lateral positioning and moving mechanism for a center frame for a roll grinder. Utility Model Content

[0011] In order to position both sides of the center frame body and improve the stability of the center frame body, preferably, positioning nuts are provided on both sides of the outside of the screw rod, and the positioning nuts are threadedly connected to the outside of the screw rod.

[0012] Technical effects and advantages of the utility model:

[0013] 1. By setting up the lubrication structure, the lubricating oil inside the oil storage ring of the oil storage ring enters into the corresponding oil filling pipe through the oil through hole, and the center frame body moves on the threaded tube and the screw rod, and the guide tube and the slide rod slide, which can drive the two oil storage rings to slide outside the screw rod and the slide rod respectively.

[0024] Specifically, in this structure, the mounting seat 1 can be installed at a specified position of the roll grinder, and the center frame body 2 is used to support the roll. When the center frame body 2 is moved laterally, the servo motor 5 drives the screw 4 to rotate inside the mounting seat 1, so that the threaded tube 7 embedded in the center frame body 2 moves outside the screw 4, and the center frame body 2 is slidably guided on the outside of the slide rod 3 through the guide tube 6, so that the center frame body 2 can be moved laterally.

[0025] In a specific embodiment, as shown in the attached Figure 1 , 4As shown in , 5 and 6, one end of the guide cylinder 6 and the threaded cylinder 7 are fixedly provided with a lubrication structure, and the lubrication structure includes an oil storage ring 8, which is fixedly installed at one end of the guide cylinder 6 and the threaded cylinder 7, respectively, and an oil storage tank 9 is arranged inside the oil storage ring 8, and a plurality of oil holes 10 are opened in an annular shape at the bottom of the inner cavity of the oil storage tank 9, and the interiors of the plurality of oil holes 10 are connected with oil injection pipes 11, and an oil ring 12 is fixedly installed inside the oil injection pipe 11, and a ball seat 13 is slidably provided on one side of the oil ring 12, and a lubricating ball 14 is rotatably provided inside the ball seat 13, and the lubricating ball 14 extends To the outside of the oil filling pipe 11, a plurality of springs 15 are fixedly arranged between the oil through ring 12 and the ball seat 13, and the two oil storage rings 8 are respectively slidably connected to the outside of the screw rod 4 and the sliding rod 3, and the inner diameter of the oil storage ring 8 is larger than the outer diameter of the screw rod 4 and the sliding rod 3.

The oil filling hole is connected to the oil storage tank 9, and the oil filling pipe 11 extends to the inside of the oil storage ring 8 through the oil through hole 10. The outer wall of the ball seat 13 is slidably connected to the inner wall of the oil filling pipe 11, and the lubricating ball 14 is fitted inside the thread groove of the screw rod 4.

[0026] Specifically, the structure can be used to lubricate the connection between the threaded cylinder 7 and the screw rod 4 and the connection between the guide cylinder 6 and the slide rod 3, reduce wear and increase service life. Specifically, first, the sealing plug 18 is screwed out to open the oil filling hole, and the operator pours the lubricating oil into the inside of the oil storage ring 8 through the oil filling hole, and the lubricating oil is stored in the oil storage tank 9. The sealing plug 18 is closed, and the lubricating oil in the oil storage tank 9 enters the corresponding oil filling pipe 11 through multiple oil holes 10;

[0027] When the screw rod 4 is running, first the screw rod 4 drives the threaded cylinder 7 to move, and makes the guide cylinder 6 slide outside the slide rod 3. Since the two oil storage rings 8 are respectively located outside the screw rod 4 and the slide rod 3 for sliding connection, and the inner diameter of the oil storage ring 8 is larger than the outer diameter of the screw rod 4 and the slide rod 3, the rotation of the screw rod 4 can make the multiple lubricating balls 14 roll in the threaded groove of the screw rod 4 and roll in the outside of the slide rod 3.

In specific operation, first, a mounting seat 1 can be mounted at a designated position of the roll grinder, and a center frame body 2 is used to support the roll. When the center frame body 2 is moved laterally, a servo motor 5 drives a screw rod 4 to rotate inside the mounting seat 1, so that a threaded cylinder 7 embedded in the center frame body 2 moves outside the screw rod 4, and the center frame body 2 is slidably guided outside the slide rod 3 through a guide cylinder 6, so that the center frame body 2 can be moved laterally.

[0035] When the center frame body 2 is displaced, the ball 16 arranged at the bottom can roll and fit with the mounting base, which is beneficial to reduce friction and improve the smoothness of use;

[0036] At the same time, the movement of the center frame body 2 can drive the two oil storage rings 8 to slide outside the screw rod 4 and the slide rod 3 respectively. At this time, the lubricating balls 14 are respectively attached to the outside of the slide rod 3 and the screw rod 4. When the lubricating balls 14 roll, the lubricating oil inside the oil filling pipe 11 can be discharged, thereby lubricating the outside of the screw rod 4 and the slide rod 3, reducing wear and prolonging service life.

[0037] After the center frame body 2 is moved, the positioning nuts 17 rotate on the external threads of the screw rod 4 to displace the two positioning nuts 17. The positioning nuts 17 can be respectively positioned close to both sides of the center frame body 2 to avoid slipping during use and improve the stability of the center frame body 2.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
