Description

Technical Field

[0001] This utility model belongs to the field of grinding technology and relates to a large horizontal spindle rotary table surface grinder with adjustable worktable angle. Background Technology

[0002] A grinding machine is a machine tool that uses an abrasive tool to grind the surface of a workpiece. Grinding machines typically include a rotary table for positioning the workpiece, which drives the workpiece to rotate in conjunction with the abrasive tool for grinding. However, the rotary table is usually fixed to the machine bed, which means that once the workpiece is fixed on the rotary table, its angle and position cannot be adjusted. This results in the workpiece only being able to rotate on a fixed plane, failing to meet the needs of machining at different angles. This is especially true for large grinding machines, which, to ensure machining stability, mostly use fixed rotary tables, leading to a limited functionality of the grinding machine. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a large horizontal spindle rotary table surface grinder with an adjustable worktable angle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A large horizontal spindle rotary table surface grinder with adjustable worktable angle includes a frame, a support base on the mounting platform of the frame, a workpiece rotary table assembly on the support base, a rotation adjustment device between the support base and the mounting platform, and a crossbeam on the frame, which is connected to a grinding wheel assembly via a horizontal and vertical moving mechanism.

[0006] The grinding wheel assembly, through a horizontal and vertical movement mechanism, can be moved laterally and vertically to a designated processing position to perform grinding on a rotating workpiece. It can handle the multi-directional processing needs of complex workpieces. The rotation adjustment device can drive the support base to rotate to adjust the parallelism between the workpiece rotary table assembly and the mounting platform, thereby adjusting the angle and position of the workpiece. The workpiece can be ground at different angles without frequent workpiece changes or adjustments to the grinding machine position, thus saving time, improving processing efficiency, and adapting to the processing needs of workpieces at different angles, enhancing the functionality of the grinding machine.

[0007] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, the rotation adjustment device includes a rotating shaft disposed on one side of the bottom end of the support base, a rotating seat that cooperates with the rotating shaft on the mounting platform, a rotation drive mechanism that can drive the support base to rotate around the rotating shaft to adjust the angle of the support base at the bottom end, and a positioning and fixing mechanism that can position and fix the support base after the angle of the support base is adjusted between the support base and the mounting platform.

[0008] The rotation drive mechanism can drive the support base to rotate around the rotation axis to adjust the angle and position of the workpiece. The positioning and fixing mechanism is used to position and fix the support base after the angle adjustment is completed, so as to ensure the stability of the support base and guarantee the stability of the workpiece processing.

[0009] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, the positioning and fixing mechanism includes locking and fixing plates respectively arranged on both sides of the support base away from the rotation axis. The bottom end of the locking and fixing plate is fixed to the mounting platform. The locking and fixing plate is provided with an arc-shaped adjustment groove. The support base and the locking and fixing plate are fixed by locking bolts passing through the arc-shaped adjustment groove.

[0010] When it is necessary to adjust the angle of the workpiece, first loosen the locking bolts on both sides of the support base, and then rotate the drive mechanism to drive the support base to rotate around the rotation axis. During the rotation of the support base, the locking bolts on both sides slide in their respective arc-shaped adjustment grooves. The arc-shaped adjustment grooves play an arc-shaped guiding role for the locking bolts. After the angle of the support base is adjusted, tighten the locking bolts on both sides of the support base to make the support base and the locking plates on both sides firmly fixed. The locking plates play a fixed support role for the support base to ensure the stability of the support base and ensure the stability of the workpiece processing.

[0011] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, the rotation drive mechanism is arranged between the positioning and fixing mechanism and the rotating shaft. The rotation drive mechanism includes an adjusting screw arranged at the bottom of the support base, and the adjusting screw is connected to the screw rotation drive mechanism.

[0012] The screw rotation drive mechanism can drive the adjusting screw to rotate. When the adjusting screw rotates in the forward or reverse direction, it will generate a thrust or pull along the helical direction. This thrust or pull acts on the support base and can drive the support base to rotate around the rotation axis, thereby adjusting the angle and position of the workpiece.

[0013] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, the workpiece rotary table assembly includes a pulley mounted on a support base. The pulley and the support base are rotatably connected by a rotating structure. An electromagnetic chuck is provided at the upper end of the pulley. A rotary drive mechanism is also provided between the pulley and the support base.

[0014] The workpiece is positioned and fixed on the electromagnetic chuck, and the rotary drive mechanism can drive the pulley to rotate on the support base, thereby causing the workpiece to rotate.

[0015] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, the rotating structure includes a central positioning spindle mounted on a support base, a positioning shaft hole on the pulley that mates with the central positioning spindle, a plurality of positioning bearings between the positioning shaft hole and the central positioning spindle, and a bearing locking nut at the upper end of the central positioning spindle.

[0016] Several positioning bearings between the positioning shaft hole and the central positioning spindle provide support, reducing friction between the positioning shaft hole and the central positioning spindle and maintaining better rotational accuracy of the pulley.

[0017] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, a number of fan-shaped oil cavities are provided on the upper end surface of the support base in contact with the pulley, which are evenly distributed around the central positioning spindle. The fan-shaped oil cavities are connected to the oil supply assembly through the oil supply channel. The support base is provided with a number of annular positioning platforms, and the bottom end of the pulley is provided with an annular positioning groove adapted to the annular positioning platform.

[0018] The fluid oil entering the fan-shaped oil chamber through the oil supply assembly and oil supply channel can form a thin film on the contact surface between the support and the pulley, which can reduce the friction between the support and the pulley. The fan-shaped oil chamber and the support are designed as an integral unit, which is convenient for installation and adjustment. The uniform fan-shaped oil chamber can more effectively distribute pressure, making the pulley more stable when under force, and enabling the pulley to maintain higher precision under low pressure.

[0019] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, the horizontal and vertical movement mechanism includes a horizontally sliding body connected to a crossbeam body, a horizontal drive structure between the crossbeam body and the horizontally sliding body, a vertically sliding plate connected to the horizontally sliding body, a vertical drive structure between the vertically sliding plate and the horizontally sliding body, and the grinding wheel assembly horizontally arranged on the vertically sliding plate.

[0020] The transverse drive structure can drive the transverse drag body to slide laterally on the crossbeam to adjust the transverse position of the grinding wheel assembly. The vertical drive structure can drive the vertical sliding plate to slide vertically on the transverse drag body to adjust the vertical position of the grinding wheel assembly. The grinding wheel assembly can be moved laterally and vertically, and can meet the multi-directional processing needs of complex workpieces.

[0021] In the aforementioned large horizontal spindle rotary table surface grinder with adjustable table angle, the cross-section of the transverse drag body is L-shaped, and two sets of first slide rails distributed transversely are provided on the side wall of the transverse beam. The transverse drag body is provided with a first sliding block that slides and engages with the first slide rails on the side wall corresponding to the transverse beam. The transverse drive structure includes a transverse lead screw horizontally arranged on the side wall of the transverse beam between the two sets of first slide rails. The transverse lead screw is connected to a transverse driver, and the transverse lead screw nut is connected to the transverse drag body. The upper end of the transverse beam is provided with a second slide rail distributed transversely, and the end face of the transverse drag body is provided with a second sliding block that slides and engages with the second slide rail.

[0022] The transverse drive can drive the transverse lead screw to rotate. The rotation of the transverse lead screw nut can drive the transverse drag body to slide laterally on the crossbeam. The sliding accuracy and stability of the transverse drag body on the crossbeam are high, which ensures the accuracy and stability of workpiece processing.

[0023] In the above-mentioned large horizontal spindle rotary table surface grinder with adjustable worktable angle, vertical sliders are respectively provided on both sides of the vertical sliding plate, and vertical slide grooves that slide and cooperate with the vertical sliders are provided on the horizontal drag body. The vertical drive structure includes a vertical lead screw vertically arranged on the horizontal drag body, the vertical lead screw is connected to a vertical driver, and the vertical lead screw nut of the vertical lead screw is connected to the vertical sliding plate.

[0024] The vertical actuator can drive the vertical lead screw to rotate. The rotation of the vertical lead screw, through the vertical lead screw nut, can drive the vertical sliding plate to slide vertically on the horizontal drag body. The vertical sliding plate has high stability and precision in vertical sliding, which can ensure the stability and precision of workpiece processing.

[0025] Compared with existing technologies, the advantages of this invention are as follows: 1. The fixed angle of the workpiece can be adjusted, allowing the workpiece to undergo grinding at different angles without frequent workpiece changes or adjustments to the grinding machine position, thus saving time, improving processing efficiency, and adapting to the processing requirements of different workpiece angles, enhancing the functionality of the grinding machine. 2. The support base is firmly fixed after angle adjustment, ensuring the stability of workpiece processing. 3. The high rotational precision of the pulley ensures the processing accuracy of the workpiece. Attached Figure Description

The crossbeam 6 is connected to the grinding wheel assembly 7 through a horizontal and vertical moving mechanism 8.

[0035] The crossbeam body 6 adopts a gantry structure design, which is suitable for large grinding machines. It has a simple structure and strong stability.

[0036] In this invention, the workpiece is fixed on the workpiece rotary table assembly 4, which drives the workpiece to rotate. The grinding wheel assembly 7 can be moved laterally and vertically through the horizontal and vertical moving mechanism 8, so that the grinding wheel assembly 7 can be moved to the designated processing position to perform grinding on the rotating workpiece. This can meet the multi-directional processing needs of complex workpieces. The rotation adjustment device 5 can drive the support base 3 to rotate to adjust the parallelism between the workpiece rotary table assembly 4 and the mounting platform 2, thereby adjusting the angle and position of the workpiece. The workpiece can be ground at different angles without frequently changing the workpiece or adjusting the position of the grinding machine, thus saving time, improving processing efficiency, and adapting to the processing needs of different angles of the workpiece, enhancing the functionality of the grinding machine.

[0037] Specifically, combining Figures 1-4 As shown, the rotation adjustment device 5 includes a rotation shaft 9 disposed on one side of the bottom end of the support base 3, a rotation seat 10 that cooperates with the rotation shaft 9 on the mounting platform 2, a rotation drive mechanism 11 that can drive the support base 3 to rotate around the rotation shaft 9 to adjust the angle of the support base 3 at the bottom end, and a positioning and fixing mechanism 12 that can position and fix the support base 3 after the angle of the support base 3 is adjusted between the support base 3 and the mounting platform 2.

[0038] The support base 3 and the mounting platform 2 are rotatably connected by the cooperation of the rotating shaft 9 and the rotating seat 10. The rotation drive mechanism 11 can drive the support base 3 to rotate around the rotating shaft 9 to adjust the angle and position of the workpiece. The positioning and fixing mechanism 12 between the support base 3 and the mounting platform 2 is used to position and fix the support base 3 after the angle of the support base 3 is adjusted, so as to ensure the stability of the support base 3 and guarantee the stability of the workpiece processing.

[0039] Specifically, combining Figures 1-3 As shown, the positioning and fixing mechanism 12 includes locking and fixing plates 13 respectively disposed on both sides of the support base 3 away from the rotating shaft 9. The bottom end of the locking and fixing plate 13 is fixed to the mounting platform 2. An arc-shaped adjustment groove 14 is provided on the locking and fixing plate 13. The support base 3 and the locking and fixing plate 13 are fixed by locking bolts 15 passing through the arc-shaped adjustment groove 14.

[0040] When it is necessary to adjust the angle of the workpiece, first loosen the locking bolts 15 on both sides of the support base 3, and then rotate the drive mechanism 11 to drive the support base 3 to rotate around the rotating shaft 9. During the rotation of the support base 3, the locking bolts 15 on both sides slide in their respective arc-shaped adjustment grooves 14. The arc-shaped adjustment grooves 14 play an arc-shaped guiding role for the locking bolts 15. After the angle of the support base 3 is adjusted, tighten the locking bolts 15 on both sides of the support base 3 to make the support base 3 firmly fixed to the locking plates 13 on both sides. The locking plates 13 play a fixed support role for the support base 3 to ensure the stability of the support base 3 and ensure the stability of the workpiece processing.

[0041] Specifically, combining Figure 2 and Figure 3 As shown, the rotation drive mechanism 11 is disposed between the positioning and fixing mechanism 12 and the rotating shaft 9. The rotation drive mechanism 11 includes an adjusting screw 16 disposed at the bottom end of the support base 3. The adjusting screw 16 is connected to the screw rotation drive mechanism.

[0042] The adjusting screw 16 is positioned between the positioning and fixing mechanism 12 and the rotating shaft 9. The screw rotation drive mechanism can drive the adjusting screw 16 to rotate. When the adjusting screw 16 rotates in the forward or reverse direction, the adjusting screw 16 will generate a thrust or pull along the spiral direction. This thrust or pull acts on the support 3 and can drive the support 3 to rotate around the rotating shaft 9 to adjust the angle and position of the workpiece.

[0043] Specifically, combining Figures 1-7 As shown, the workpiece rotary table assembly 4 includes a pulley 17 mounted on a support base 3. The pulley 17 and the support base 3 are rotatably connected by a rotating structure 18. An electromagnetic chuck 19 is provided at the upper end of the pulley 17. A rotary drive mechanism 20 is also provided between the pulley 17 and the support base 3.

[0044] The rotary drive mechanism 20 includes a rotary driver 21 mounted on a support base 3 via a fixed plate. The output end of the rotary driver 21 is connected to the pulley 17 via a transmission belt 45.

[0045] The workpiece is positioned and fixed on the electromagnetic chuck 19. The rotary driver 21 drives the pulley 17 to rotate on the support base 3 via the transmission belt 45, thereby causing the workpiece to rotate.

[0046] Specifically, combining Figures 3-7 As shown, the rotating structure 18 includes a central positioning spindle 22 mounted on the support base 3, a positioning shaft hole 23 on the pulley 17 that mates with the central positioning spindle 22, a plurality of positioning bearings 24 between the positioning shaft hole 23 and the central positioning spindle 22, and a bearing locking nut 25 at the upper end of the central positioning spindle 22.

[0047] Positioning bearing 24 is an angular contact bearing.

[0048] The pulley 17 is sleeved on the central positioning spindle 22 of the support base 3 through the positioning shaft hole 23. Several positioning bearings 24 between the positioning shaft hole 23 and the central positioning spindle 22 provide support, which can reduce the friction between the positioning shaft hole 23 and the central positioning spindle 22 and maintain better rotational accuracy of the pulley 17.

[0049] Preferably, combined with Figures 4-7 As shown, a number of fan-shaped oil chambers 27 are evenly distributed around the central positioning main shaft 22 on the upper end surface 26 of the support base 3 that contacts the pulley 17. The fan-shaped oil chambers 27 are connected to the oil supply assembly through the oil supply channel 28. A number of annular positioning platforms 29 are provided on the support base 3. The bottom end of the pulley 17 is provided with an annular positioning groove 30 that is adapted to the annular positioning platform 29.

[0050] The fluid oil entering the fan-shaped oil chamber 27 through the oil supply assembly and oil supply channel 28 can form a thin film on the contact surface between the support base 3 and the pulley 17, which can reduce the friction between the support base 3 and the pulley 17. The fan-shaped oil chamber 27 and the support base 3 are designed as an integral unit, which is convenient for installation and adjustment. At the same time, the fan-shaped oil chamber 27 is evenly distributed circumferentially along the central positioning main shaft 22 on the upper end surface 26 of the support base 3 and the pulley 17. The uniform fan-shaped oil chamber 27 can more effectively disperse the pressure, making the pulley 17 more stable when under force, and enabling the pulley 17 to maintain higher precision under low pressure.

[0051] Specifically, combining Figure 1 , Figure 2 and Figure 4 As shown, the horizontal and vertical moving mechanism 8 includes a horizontally sliding body 31 that is horizontally slidably connected to the horizontal beam 6, a horizontal driving structure 32 that is provided between the horizontal beam 6 and the horizontally sliding body 31, a vertically sliding plate 33 that is vertically slidably connected to the horizontally sliding body 31, a vertical driving structure 34 that is provided between the vertically sliding plate 33 and the horizontally sliding body 31, and a grinding wheel assembly 7 that is horizontally arranged on the vertically sliding plate 33.

The vertical drive structure 34 can drive the vertical sliding plate 33 to slide vertically on the transverse drag body 31 to adjust the vertical position of the grinding wheel assembly 7. The grinding wheel assembly 7 can be moved laterally and vertically, and can meet the multi-directional processing needs of complex workpieces.

[0053] Specifically, combining Figure 1 , Figure 2 and Figure 4As shown, the cross section of the horizontal drag body 31 is L-shaped. Two sets of first slide rails 35 distributed laterally are provided on the side wall of the cross beam 6. The horizontal drag body 31 is provided with a first sliding block 36 that slides and engages with the first slide rails 35 on the side wall of the cross beam 6.

The upper end of the cross beam 6 is provided with a second slide rail 38 distributed laterally. The end face of the horizontal drag body 31 is provided with a second sliding block 39 that slides and engages with the second slide rail 38.

[0054] The horizontal drag body 31 and the horizontal beam body 6 are slidably connected by the sliding fit between the first sliding block 36 and the first slide rail 35, as well as the second sliding block 39 and the second slide rail 38. This ensures the sliding accuracy and stability of the horizontal drag body 31 on the horizontal beam body 6, thereby ensuring the accuracy and stability of the workpiece processing. The operation of the horizontal drive 40 can drive the horizontal lead screw 37 to rotate. The rotation of the horizontal lead screw 37 can drive the horizontal drag body 31 to slide laterally on the horizontal beam body 6 through the horizontal lead screw nut.

[0055] Specifically, combining Figure 1 , Figure 2 and Figure 4 As shown, vertical sliders 41 are provided on both sides of the vertical sliding plate 33, and vertical grooves 42 that slide with the vertical sliders 41 are provided on the horizontal drag body 31. The vertical drive structure 34 includes a vertical lead screw 43 vertically arranged on the horizontal drag body 31.

[0056] The vertical sliding plate 33 can slide vertically within the vertical groove 42 of the horizontal drag body 31 via the vertical sliders 41 on both sides. The vertical sliding plate 33 has high stability and precision in vertical sliding, which can ensure the stability and precision of workpiece processing. The operation of the vertical driver 44 can drive the vertical lead screw 43 to rotate. The rotation of the vertical lead screw 43 can drive the vertical sliding plate 33 to slide vertically on the horizontal drag body 31 via the vertical lead screw nut.

[0057] The working principle of this utility model is as follows: the workpiece is positioned and fixed on the electromagnetic chuck 19, the rotary driver 21 drives the pulley 17 to rotate on the support seat 3 through the transmission belt 45 to drive the workpiece to rotate, the transverse driver 40 drives the transverse drag body 31 to slide laterally on the crossbeam 6 to move the grinding wheel assembly 7 laterally to the processing position, and the vertical driver 44 drives the vertical sliding plate 33 to slide vertically on the transverse drag body 31 to move the grinding wheel assembly 7 vertically to the processing position to grind the rotating workpiece.
