It is widely used in grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in workpieces. When using grinding equipment to grind milling cutters, it is necessary to adjust the workpiece to achieve a better milling cutter grinding effect. The existing grinding equipment is not convenient for adjusting the position of the workpiece, so that a better milling cutter grinding effect cannot be achieved.

[0003] Prior art CN217394499U discloses a milling cutter grinder for a vertical machining center. By starting a servo motor, the lead screw can be driven to rotate, which will move the moving block, thereby driving the workpiece to move, thereby achieving an adjustment effect. When it is necessary to clean debris on the surface of the workbench, the first bevel gear is driven to rotate by the lead screw. Because the first bevel gear is meshed with the second bevel gear, the rotating shaft can be driven to rotate, which will cause the scraper to make a circular motion, thereby driving the cleaning brush to rub on the workbench, thereby cleaning the debris on the workbench.

[0004] However, the overall flexibility of the above-mentioned grinding equipment is not high, and the workpiece cannot be processed in multiple directions, thereby reducing the processing range of the grinding equipment on the workpiece. Summary of the invention

[0034] In this embodiment, the clamping mechanism is used to clamp and fix workpieces of different sizes, and then the adjusting mechanism drives the guide block 104 to move up and down, laterally and longitudinally in the protective cover 102, thereby driving the fixed seat 105 to move up and down, laterally and longitudinally in the protective cover 102, and then driving the workpiece clamped and fixed in the fixed seat 105 to move up and down, laterally and longitudinally in the protective cover 102, so as to move the part to be ground of the workpiece to the grinding mechanism.

During the entire grinding process, the workpiece to be processed can be processed in multiple directions, thereby improving the processing range of the grinding equipment, solving the technical problem that the overall flexibility of the existing grinding equipment is not high and the workpiece cannot be processed in multiple directions, thereby reducing the processing range of the grinding equipment for processing the workpiece.

[0035] The protective cover 102 is arranged on the base 101, the protective plate 103 is movably arranged outside the protective cover 102 through a hinge 123, the limiting mechanism is used to limit and fix the protective plate 103 outside the protective cover 102, the guide block 104 is located in the protective cover 102, the adjustment mechanism is located in the protective cover 102, and is used to adjust the guide block 104 in multiple directions, the fixed seat 105 is movably arranged on the guide block 104, the clamping mechanism is located in the fixed seat 105, and is used to clamp and fix the workpiece, and the grinding mechanism is used to mill the workpiece. The knife 122 is ground, the interior of the protective cover 102 is a hollow structure, the protective plate 103 and the protective cover 102 are rotatably connected through the hinge 123, so that the protective plate 103 can be rotated outside the protective cover 102, thereby opening or closing the internal space of the protective cover 102, and the guide block 104 has a placement groove, and a rotating motor 125 is arranged in the placement groove of the guide block 104, and the output shaft of the rotating motor 125 is connected to the fixed seat 105, and drives the fixed seat 105 to rotate above the guide block 104 along the axis of the output shaft of the rotating motor 125.

[0036] Secondly, the protective plate 103 has a through hole, and the rotating rod 106 is movably arranged in the through hole of the protective plate 103. The handle 107 is arranged at the end of the rotating rod 106 away from the protective cover 102. The limit block 108 is detachably connected to the protective cover 102 and is arranged at the end of the rotating rod 106 away from the handle 107. The protective cover 102 has a groove, and the limit block 108 can be embedded in the groove of the protective cover 102. The handle 107 is held and rotated to drive the rotating rod 106 to rotate along the axis of the rotating rod 106 in the through hole of the protective plate 103, thereby driving the limit block 108 to rotate along the axis of the rotating rod 106 in the protective cover 102, so that the limit block 108 can be embedded in the groove of the protective cover 102.

[0037] At the same time, the lifting member, the moving member and the driving member are arranged in the protective cover 102 from bottom to top in sequence, the lifting member is used to move the moving member up and down, the moving member is used to move the driving member longitudinally, and the driving member is used to move the guide block 104 laterally. The number of the support columns 109 is four, and they are respectively arranged on four sides of the base 101, and all the support columns 109 are located in the protective cover 102. The movable plate 110 is slidably arranged outside the support column 109, and the up and down movement of the movable plate 110 outside the support column 109 is driven by a hydraulic telescopic rod 111. The number of the guide rails 112 is two, and they are respectively arranged on the left and right sides of the movable plate 110. The movable plate 113 is slidably arranged on the guide rails 112. The movable plate 113 is longitudinally moved on the guide rails 112. The sliding is achieved by driving an electric telescopic rod 114. There are two support plates 115, which are respectively arranged on the left and right sides of the movable plate 113. The control motor 116 is arranged outside one of the support plates 115. The screw 117 is connected to the output shaft of the control motor 116 and is arranged between the two support plates 115. The output shaft of the control motor 116 is connected to the screw 117 and drives the screw 117 to rotate along its own axis between the two support plates 115. The screw 117 has an external thread, and the guide block 104 has an internal thread. The internal thread of the guide block 104 cooperates with the external thread of the screw 117, so that the guide block 104 can move along the trajectory of the thread outside the screw 117, thereby allowing the guide block 104 to move laterally above the movable plate 113.

[0038] In addition, the connecting spring 118 is arranged in the fixing seat 105, and the clamping ring 119 is arranged on the side of the connecting spring 118 away from the fixing seat 105. The fixing seat 105 has an opening, and the clamping ring 119 is located in the opening of the fixing seat 105. The connecting spring 118 is arranged between the fixing seat 105 and the clamping ring 119. The connecting spring 118 has a self-recovering function, so that when the expansion and contraction force on the connecting spring 118 disappears, the connecting spring 118 will drive the clamping ring 119 to move in the direction of returning to its original position.

[0039] Finally, the grinding motor 120 is arranged outside the protective cover 102, the mounting rod 121 is connected to the output shaft of the grinding motor 120 and passes through the protective cover 102, the milling cutter 122 is arranged at one end of the mounting rod 121 away from the grinding motor 120, and a convex cutter 124 is arranged outside the milling cutter 122, and the convex cutter 124 is used to grind the workpiece, the output shaft of the grinding motor 120 is connected to the mounting rod 121, and drives the mounting rod 121 to rotate along its own axis, thereby driving the milling cutter 122 to rotate along its own axis in the protective cover 102.

[0040] When using a vertical machining center milling cutter grinding device of the present embodiment, the handle 107 is held and rotated to drive the rotating rod 106 to rotate along the axis of the rotating rod 106 in the through hole of the protective plate 103, thereby driving the limit block 108 to rotate along the axis of the rotating rod 106 in the protective cover 102, allowing the limit block 108 to slide out of the groove of the protective cover 102, so that the fixed state of the protective plate 103 outside the protective cover 102 is released, and then, the protective plate 103 is rotated outside the protective cover 102 to open the internal space of the protective cover 102, and then the clamping ring 119 is moved in the direction close to the fixed seat 105, so that the two clamping rings 119 move away from each other, and then the distance between the two clamping rings 119 gradually increases. At this time, the connecting spring 118 will be compressed.

[0041] When the distance between the two clamping rings 119 reaches the maximum, the workpiece is placed between the two clamping rings 119, and the clamping rings 119 are loosened, so that the compression force on the connecting spring 118 disappears. Since the connecting spring 118 has a self-restoring effect, the connecting spring 118 drives the clamping ring 119 to move in the direction of restoring to the original position until the clamping ring 119 contacts the workpiece, so that the two clamping rings 119 can clamp and fix the workpiece together. After clamping and fixing, hold the handle 107 and turn the handle 107. 07 is used to drive the rotating rod 106 to rotate in the through hole of the protective plate 103 along the axis of the rotating rod 106, thereby driving the limit block 108 to rotate in the protective cover 102 along the axis of the rotating rod 106, and embedding the limit block 108 into the groove of the protective cover 102, so that the protective plate 103 is limited and fixed on the outside of the protective cover 102 and cannot continue to rotate, thereby realizing the closure of the internal space of the protective cover 102 to avoid the situation where the debris generated by grinding will splash around when the workpiece is ground.

[0042] Afterwards, the hydraulic telescopic rod 111 is started, so that the power output from the output end of the hydraulic telescopic rod 111 drives the movable plate 110 to slide up and down outside the support column 109, driving the guide block 104 to move up and down in the protective cover 102, thereby driving the fixed seat 105 to move up and down in the protective cover 102, and then driving the workpiece clamped and fixed in the fixed seat 105 to move up and down, and starting the electric telescopic rod 114, so that the power output from the output end of the electric telescopic rod 114 drives the movable plate 113 to slide longitudinally on the guide rail 112, driving the guide block 104 to move longitudinally in the protective cover 102, thereby driving the fixed seat 105 to move longitudinally in the protective cover 102, thereby driving the workpiece clamped and fixed in the fixing seat 105 to move longitudinally in the protective cover 102, and starting the control motor 116, so that the power output by the output shaft of the control motor 116 drives the screw 117 to rotate along its own axis between the two support plates 115, and drives the guide block 104 to move laterally between the two support plates 115, thereby driving the fixing seat 105 to move laterally in the protective cover 102, and then driving the workpiece clamped and fixed in the fixing seat 105 to move laterally in the protective cover 102, through the up and down movement, longitudinal movement and lateral movement of the workpiece, the part to be ground of the workpiece can be moved to the milling cutter 122.

[0043] When the part to be ground of the workpiece moves to the milling cutter 122, the grinding motor 120 is started, so that the power output by the output shaft of the grinding motor 120 drives the mounting rod 121 to rotate along its own axis, thereby driving the milling cutter 122 to rotate along its own axis in the protective cover 102, and then the milling cutter 122 can grind the part to be ground of the workpiece clamped and fixed in the fixing seat 105.

[0044] Restart the rotating motor 125 so that the power output by the output shaft of the rotating motor 125 drives the fixed seat 105 to rotate above the guide block 104 along the axis of the output shaft of the rotating motor 125, thereby driving the workpiece clamped in the fixed seat 105 to rotate above the guide block 104 along the axis of the output shaft of the rotating motor 125, so that the milling cutter 122 can grind different positions of the workpiece.

[0048] Specifically, the handle 107 is held and rotated to drive the rotating rod 106 to rotate in the through hole of the protective plate 103 along the axis of the rotating rod 106, thereby driving the limit block 108 to rotate in the protective cover 102 along the axis of the rotating rod 106, allowing the limit block 108 to slide out of the groove of the protective cover 102, so that the fixed state of the protective plate 103 outside the protective cover 102 is released, and then, the protective plate 103 is rotated outside the protective cover 102 to open the internal space of the protective cover 102, and then the clamping ring 119 is moved in the direction close to the fixed seat 105, so that the two clamping rings 119 move away from each other, and then the distance between the two clamping rings 119 gradually increases. At this time, the connecting spring 118 will be compressed.

[0049] S2. When the distance between the two clamping rings 119 reaches the maximum, the workpiece is placed between the two clamping rings 119, and the clamping rings 119 are released. Under the action of the connecting spring 118, the clamping rings 119 move toward the direction of returning to the original position to clamp and fix the workpiece.

[0050] Specifically, when the distance between the two clamping rings 119 reaches the maximum, the workpiece is placed between the two clamping rings 119, and the clamping ring 119 is loosened, so that the compression force on the connecting spring 118 disappears. Since the connecting spring 118 has a self-restoring effect, the connecting spring 118 drives the clamping ring 119 to move in the direction of restoring to the original position until the clamping ring 119 contacts the workpiece, so that the two clamping rings 119 can clamp and fix the workpiece together. After clamping and fixing, hold the handle 107 and turn the handle Hand 107 is used to drive the rotating rod 106 to rotate along the axis of the rotating rod 106 in the through hole of the protective plate 103, thereby driving the limit block 108 to rotate along the axis of the rotating rod 106 in the protective cover 102, and embedding the limit block 108 into the groove of the protective cover 102, so that the protective plate 103 is limited and fixed on the outside of the protective cover 102 and cannot continue to rotate, thereby realizing the closure of the internal space of the protective cover 102 to avoid the debris generated by grinding from splashing everywhere when grinding the workpiece.

[0054] S32, starting the electric telescopic rod 114, the power output from the output end of the electric telescopic rod 114 drives the moving plate 113 to slide longitudinally on the guide rail 112, driving the guide block 104 to move longitudinally, thereby driving the fixing seat 105 to move longitudinally, and further driving the workpiece to move longitudinally;

[0055] S33, start the control motor 116, the power output by the output shaft of the control motor 116 drives the screw 117 to rotate along its own axis between the two support plates 115, driving the guide block 104 to move horizontally between the two support plates 115, thereby driving the fixing seat 105 to move horizontally, and further driving the workpiece to move horizontally;
