Then, a diamond pen is used to contact the cup-shaped grinding wheel, which can facilitate the dressing of the cup-shaped grinding wheel. However, after the device is stopped, external debris is likely to fall into the working area of the diamond pen under the action of gravity or equipment vibration, which may cause micro-cracks in the diamond tip, thereby affecting the machining accuracy of the device.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1
[0030] Please see Figures 1 to 4This embodiment provides a technical solution: a cup-shaped grinding wheel dressing device, including a fixed base 4, a drive unit 2, and a protective mechanism 1. The drive unit 2 is located inside the fixed base 4, and the protective mechanism 1 is located at the top of the drive unit 2. The protective mechanism 1 includes an electric push rod 102 located at the top of the drive unit 2. By driving a reduction mechanism with a built-in motor to reduce the speed and increase the torque, the rotational motion of the motor can be converted into the linear reciprocating motion of the push rod. During the movement, a linear guide rail or guide rod provides high-precision guidance to ensure that the push rod runs smoothly in a predetermined direction. At the same time, the stroke is controlled by a limit switch or sensor. When selecting, the appropriate model should be selected according to the actual needs. All the components required in the electric push rod 102 are existing technologies and will not be described in detail below.
[0031] The output end of the electric actuator 102 is fixedly connected to a movable base 101. A support base 107 is fixedly connected to the top of the movable base 101. A primary motor 103 is fixedly connected to one side of the support base 107. A rotating rod 106 is fixedly connected to the output end of the primary motor 103. A component seat 104 is fixedly connected to the side of the rotating rod 106 away from the primary motor 103. A diamond pen 105 is fixedly connected inside the component seat 104. The primary motor 103 converts electrical energy into mechanical energy through electromagnetic induction, driving the rotating shaft to rotate at high speed. The output power is reduced by a worm gear reducer. After increasing the speed and torque, it is transmitted to the rotating rod 106, causing it to swing or rotate around the fixed axis, thereby realizing the angle flipping of the diamond pen 105 and the accessory seat 104. During the movement, the rotational freedom of the diamond pen 105 is constrained by mechanical structures such as guide keys and thrust bearings. With the help of limit switches or encoder feedback, the rotating rod 106 is accurately positioned at the predetermined angle to meet the high-precision requirements of the trimming device for switching the pen tip direction. When selecting it, the appropriate model should be selected according to the actual needs. All the components required in the electric push rod 102 are existing technologies and will not be described in detail below.
[0032] A protective seat 108 is provided on the side of the top of the drive unit 2 away from the electric push rod 102. A protective groove is provided at the top of the protective seat 108. The protective groove is circular and can be inserted into the protective groove inside the protective seat 108 to protect the tip of the diamond pen 105. A protective pad 109 is provided inside the protective seat 108. The protective pad 109 is made of polyurethane and can protect the diamond pen 105.
[0033] The effect achieved by the entire embodiment is as follows: the first motor 103 is started by the control switch, the first motor 103 drives the rotating rod 106 to rotate 90° clockwise, which drives the diamond pen 105 to complete the pen tip direction flip. Then, the electric push rod 102 drives the movable seat 101 to move vertically downward, so that the diamond pen 105 is accurately inserted into the protective seat 108, which can conveniently protect the diamond pen 105 and effectively extend the service life of the diamond pen 105.
[0034] Example 2
[0035] The drive unit 2 includes a second motor 201 located in the middle of one end of the fixed base 4. The second motor 201 operates based on the principle that a current-carrying conductor moves under the force of a magnetic field. The stator generates a magnetic field, and the coils on the rotor become current-carrying conductors after being energized. Under the action of the Ampere force in the magnetic field, torque is generated, causing the rotor to rotate. Simultaneously, the commutator continuously changes the direction of the coil current, ensuring that the rotor rotates continuously in the same direction. When selecting the appropriate model, it should be chosen according to actual needs. All components required within the second motor 201 are existing technologies and will not be described in detail below.
[0036] The output end of the second motor 201 is provided with a lead screw 203, and a threaded seat 204 is provided on the outside of the lead screw 203. A support plate 202 is provided on the top of the threaded seat 204. The electric push rod 102 and the protective seat 108 are both connected to the support plate 202 by fixing bolts.
[0037] The effect achieved by the entire second embodiment is as follows: by using the operation of the second motor 201, the lead screw 203 can be driven to rotate, thereby driving the support plate 202 to move, and the diamond pen 105 can be controlled to contact the surface of the high-speed rotating cup-shaped grinding wheel, and the cup-shaped grinding wheel contour can be trimmed through a single-point cutting process.
[0038] Example 3
[0039] A support frame 3 is provided at the top end of the fixed base 4 away from the support plate 202. The support frame 3 and the fixed base 4 form a welded integrated structure, which can improve the stability of the support frame 3 during operation. A third motor 5 is provided on one side of the support frame 3. The third motor 5 has the same basic working principle as the second motor 201, which will not be described in detail here. A fixed seat 6 is provided at the output end of the third motor 5. A threaded limit block is provided on the outside of the fixed seat 6. The cup-shaped grinding wheel can be clamped by the engagement of the threaded limit block and the fixed seat 6.
[0040] The effect achieved by the entire embodiment three is that the operation of motor 5 can drive the fixed base 6 to rotate at a constant speed.
[0041] Working principle: First, the power is turned on, and the cup-shaped grinding wheel is clamped on the outside of the fixed seat 6 by the threaded limit block. Then, the control switch is used to start the No. 3 motor 5. The No. 3 motor 5 drives the cup-shaped grinding wheel to rotate at a constant speed through the flexible coupling. Then, the No. 2 motor 201 is used to drive the lead screw 203 to rotate, which can drive the support plate 202 to move. This can control the diamond pen 105 to contact the surface of the high-speed rotating cup-shaped grinding wheel, and complete the dressing of the cup-shaped grinding wheel contour through the single-point cutting process.
[0042] Finally, the control switch is used to start the first motor 103. The first motor 103 drives the rotating rod 106 to rotate 90° clockwise, causing the diamond pen 105 to complete the pen tip direction flip. Subsequently, the electric push rod 102 drives the movable seat 101 to move vertically downward, so that the diamond pen 105 is accurately inserted into the protective seat 108, which can conveniently protect the diamond pen 105 and effectively extend the service life of the diamond pen 105.
