Description

Technical Field

[0001] The utility model relates to the technical field of numerical control grinders, in particular to a numerical control grinding machine with a grinding wheel that can be easily moved. Background Art

[0002] A grinder is a widely used mechanical processing equipment. Its main structure includes a frame, PLC, motor drive mechanism, grinding wheel, etc.

[0003] Most of the existing CNC surface grinders are large in size, and most of them have a base in direct contact with the ground. When they need to be moved, lifting equipment is generally used to move them. However, when the space in the workshop is small, it is not suitable for external large-scale lifting equipment to enter and operate, which makes it troublesome to move the position and inconvenient to make fine adjustments to the position, which is very inconvenient. In addition, there are no supporting feet under the CNC surface grinder to support it, which makes the CNC surface grinder easily corroded after being in contact with the ground for a long time, which brings a lot of inconvenience to the work and affects the processing accuracy of the CNC surface grinder over time. Utility Model Content

[0008] Among them, a groove is opened at the bottom of the grinding machine base, and a lifting device is arranged in the groove, and the lifting device includes four fixing seats;

[0009] Among them, the four fixing seats are respectively fixedly connected to the two inner walls of the groove, the first fixing shafts are fixedly connected inside the four fixing seats, and the outer surfaces of the first fixing shafts are rotatably connected to the arc-shaped support plates;

[0010] Wherein, both sides of one end of the arc-shaped support plate away from the first fixed axis are fixedly connected with axles, and the outer surfaces of the axles are rotatably connected with wheels for moving equipment.

[0011] Preferably, the outer surfaces of the four arc-shaped support plates are all provided with movable grooves, the inner middle positions of the movable grooves are fixedly connected with central fixed shafts, and the outer surfaces of the central fixed shafts are rotatably connected with lower pressure plates.

[0012] Preferably, a motor is fixedly connected to the top wall of the groove, a screw is fixedly sleeved on the outer surface of the output shaft of the motor, and a transverse plate is threadedly sleeved on the outer surface of the screw.

[0013] Preferably, both ends of the transverse plate are fixedly connected with side fixing plates, the opposite sides of the two side fixing plates are fixedly connected with two second fixing shafts, and one end of the lower pressure plate away from the central fixing shaft is rotatably connected with the corresponding second fixing shaft.

[0014] Preferably, a display screen is provided on the upper surface of the grinder base, and a control console for controlling the grinder is provided on the front surface of the grinder base.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a conveniently movable CNC grinding machine for grinding wheels, which has the following beneficial effects:

[0017] When the motor is started, the output shaft of the motor rotates to drive the screw thereon to rotate. When the screw rotates, it applies a downward force to the cross plate through the thread on itself, so that the cross plate moves downward. When the cross plate moves downward, the upper ends of the four lower pressure plates are driven to move downward through the second fixed shafts on the side fixed plates on both sides. While the upper ends of the lower pressure plates move downward, a downward force is applied to the arc support plate through the central fixed shaft thereon. When the arc support plate is subjected to the force transmitted by the central fixed shaft, the arc support plate will rotate with the axis of the first fixed shaft as the center of the circle. When the arc support plate rotates with the axis of the first fixed shaft as the center of the circle, the wheel will be driven downward through the wheel axle at its lower end until the wheel contacts the ground. Finally, through the continuous rotation of the motor, the wheel can lift the whole body and make the supporting foot leave the ground. At this time, the operator can push the CNC machining grinder to move and adjust the position, thereby avoiding the situation that when the space in the workshop is small and the large external lifting equipment is inconvenient to enter, the CNC grinder cannot be moved.

[0018] 2. The CNC grinding machine with a movable grinding wheel has a certain axial self-locking property between the screw and the cross plate. At this time, even if the motor is suddenly powered off, the CNC grinding machine will not be suddenly retracted, which ensures the stability of the equipment to a certain extent. The coordinated operation of the side fixing plate, the arc support plate and the lower pressure plate can further increase the downward force of the cross plate by several times, so that the motor can lift the CNC grinding machine more easily and conveniently, avoiding the situation that the equipment is too heavy to be easily moved, so that the heavier CNC grinding machine can be easily moved.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3The utility model provides a new technical solution: a conveniently movable grinding wheel CNC machining grinder, comprising a grinder base 1, the lower surface of the grinder base 1 is fixedly connected with four supporting feet 17, the lower surface of the supporting feet 17 is shock-absorbing rubber, the upper surface of the grinder base 1 is provided with a CNC machining grinder 18, the bottom of the grinder base 1 is provided with a groove 19, a lifting device is provided in the groove 19, the lifting device comprises four fixed seats 2, the four fixed seats 2 are respectively fixedly connected to the two inner walls of the groove 19, the four fixed seats 2 are all fixedly connected with a first fixed shaft 3, the outer surface of the first fixed shaft 3 is rotatably connected with an arc-shaped support plate 4, the two sides of the end of the arc-shaped support plate 4 away from the first fixed shaft 3 are fixedly connected with a wheel shaft 5, and the outer surface of the wheel shaft 5 is rotatably connected with a wheel shaft 5 for moving The wheels 6 of the movable equipment, the outer surfaces of the four arc-shaped support plates 4 are all provided with movable grooves 7, the inner middle positions of the movable grooves 7 are fixedly connected with the central fixed shaft 8, the outer surfaces of the central fixed shaft 8 are rotatably connected with the lower pressure plate 9, the top wall of the groove 19 is fixedly connected with the motor 10, the outer surface of the output shaft of the motor 10 is fixedly sleeved with a screw 11, the outer surface of the screw 11 is threadedly sleeved with a cross plate 12, both ends of the cross plate 12 are fixedly connected with side fixing plates 13, the opposite sides of the two side fixing plates 13 are fixedly connected with two second fixed shafts 14, the end of the lower pressure plate 9 away from the central fixed shaft 8 is rotatably connected with the corresponding second fixed shaft 14, the upper surface of the grinder base 1 is provided with a display screen 15, and the front surface of the grinder base 1 is provided with a control console 16 for controlling the grinder.When it is necessary to move the CNC grinding machine 18, the motor 10 is started, and the output shaft of the motor 10 rotates to drive the screw 11 thereon to rotate. When the screw 11 rotates, it applies a downward force to the cross plate 12 through the thread on itself, so that the cross plate 12 moves downward. When the cross plate 12 moves downward, the second fixed shaft 14 on the side fixed plates 13 on both sides drives the upper ends of the four lower pressing plates 9 to move downward. While the upper ends of the lower pressing plates 9 move downward, the central fixed shaft 8 thereon applies a downward force to the arc-shaped support plate 4. When the arc-shaped support plate 4 is subjected to the force transmitted by the central fixed shaft 8, the arc-shaped support plate 4 will rotate with the axis of the first fixed shaft 3 as the center of the circle. When the arc-shaped support plate 4 rotates with the axis of the first fixed shaft 3 as the center of the circle, it will drive the wheel 6 to move downward through the wheel axle 5 at its lower end until the wheel 6 contacts the ground. After that, through the continuous rotation of the motor 10, the wheel 6 will eventually be able to lift the whole, so that the supporting foot 17 is off the ground. At this time, the operator can push the CNC machining The grinder 18 is moved and adjusted in position. Since there is a certain axial self-locking property between the screw rod 11 and the cross plate 12, even if the motor 10 is suddenly powered off, the CNC machining grinder 18 will not be suddenly retracted, which ensures the stability of the equipment to a certain extent. The above structure can make the heavier CNC machining grinder 18 easily moved, avoiding the situation where the workshop space is small and the external large-scale lifting equipment is inconvenient to enter and the CNC grinding machine cannot be moved. The coordinated operation of the screw rod 11 and the cross plate 12 can increase the torque of the motor 10 when it is converted into a linear force, so that the CNC machining grinder 18 can be lifted more easily, and the coordinated operation between the side fixing plate 13, the arc-shaped support plate 4 and the lower pressure plate 9 can further increase the downward force of the cross plate 12 by several times, so that the motor 10 can lift the CNC machining grinder 18 more easily and conveniently, avoiding the situation where the equipment is too heavy to be easily moved.

[0025] Working principle: When the CNC machining grinder 18 needs to be moved, the motor 10 is started, and the output shaft of the motor 10 rotates to drive the screw 11 thereon to rotate. When the screw 11 rotates, it applies a downward force to the cross plate 12 through the thread on itself, so that the cross plate 12 moves downward. When the cross plate 12 moves downward, the upper ends of the four lower pressure plates 9 are driven to move downward through the second fixed shafts 14 on the side fixed plates 13 on both sides. When the upper ends of the lower pressure plates 9 move downward, a downward force is applied to the arc support plate 4 through the central fixed shaft 8 thereon. When the arc support plate 4 is subjected to the force transmitted from the central fixed shaft 8, the arc support plate 4 will rotate with the axis of the first fixed shaft 3 as the center of the circle, and the arc support plate 4 will rotate with the axis of the first fixed shaft 3 as the center of the circle. When rotating about the center of a circle, the wheel 6 will be driven downward by the axle 5 at its lower end until the wheel 6 contacts the ground. Through the continuous rotation of the motor 10, the wheel 6 will eventually be lifted as a whole, so that the supporting foot 17 is off the ground. At this time, the operator can push the CNC machining grinder 18 to move and adjust the position. Since there is a certain axial self-locking property between the screw 11 and the cross plate 12, even if the motor 10 is suddenly powered off, the CNC machining grinder 18 will not be suddenly retracted, which ensures the stability of the equipment to a certain extent. The coordinated operation of the screw 11 and the cross plate 12 can increase the torque of the motor 10 when it is converted into a linear force, so that the CNC machining grinder 18 can be lifted more easily.
