Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel dressing equipment, and in particular to a diamond grinding wheel dressing device. Background Technology

[0002] A diamond grinding wheel dressing device is a tool used for precision dressing of grinding wheels. Its core component is a high-hardness diamond dressing pen, dressing block, or roller, which, through CNC or manual control, contacts the rotating grinding wheel along a specific path. Through high-precision feed and control, it effectively removes passivated abrasive grains, bonding agents, and blockages from the grinding wheel surface, and precisely reshapes the grinding wheel's working profile, thereby restoring the grinding wheel's sharpness, geometric accuracy, and grinding performance, ensuring the final machining quality and dimensional accuracy of the workpiece.

[0003] However, existing dressing equipment may experience problems such as loose clamping, uneven force, or slippage when fixing the grinding wheel, which can affect dressing accuracy and even lead to safety accidents. Furthermore, when using two cutting heads to dress the surface of the grinding wheel, it is often necessary to manually adjust the distance between the two cutting heads to make them symmetrical and contact the grinding wheel surface at the same time, which is very difficult and time-consuming, making it difficult to guarantee accuracy. Utility Model Content

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

[0005] A diamond grinding wheel dressing device includes a dressing base, a fixed outer shell fixedly installed on one side of the dressing base, a rotating base rotatably passing through one side of the fixed outer shell, a threaded sleeve fixedly installed on one side of the rotating base, and a guide base fixedly fitted on the outer side of the threaded sleeve; a negative pressure chamber fixedly installed on one side of the dressing base, an exhaust fan fixedly installed on the top of the negative pressure chamber, a negative pressure cavity opened inside the negative pressure chamber, and the input end of the exhaust fan extending into the negative pressure cavity; a worktable fixedly installed on one side of the dressing base, an adjusting base slidably installed on the top of the worktable, an adjusting groove opened on one side of the adjusting base, two threaded sliders slidably installed on the inner side of the adjusting groove, and a tool holder fixedly installed on the top of each of the two threaded sliders.

[0006] Specifically, a magnetic groove is provided on one side of the fixed housing, and a fixing magnetic ring is fixedly installed on the bottom inner wall of the magnetic groove. A protective housing is provided on one side of the fixed housing, and an installation magnetic ring is fixedly installed on the side of the protective housing close to the fixed housing. The installation magnetic ring and the fixing magnetic ring are magnetically connected. Through the magnetic connection, the protective housing can be easily installed or removed, which facilitates the installation or replacement of the grinding wheel. At the same time, it avoids the inconvenience caused by using screws and other fasteners, and simplifies the operation process.

[0007] Specifically, a drive port is provided on one side of the dressing base, and a drive servo motor is fixedly installed on the bottom inner wall of the drive port. The output shaft of the drive servo motor is fixedly connected to the rotating base. The drive servo motor can provide precise speed and torque control to ensure that the grinding wheel rotates at a stable and controllable speed during the dressing process, which is crucial for obtaining consistent and high-quality dressing results.

[0008] Specifically, the inner side of the threaded sleeve is threaded with a threaded rod, and a linkage head is fixedly installed on the end of the threaded rod away from the threaded sleeve. A linkage disc is rotatably sleeved on the outer side of the linkage head. By rotating the threaded rod, it moves axially along the inner thread of the threaded sleeve.

[0009] Specifically, the outer side of the guide base is provided with multiple guide grooves, and the inner side of each guide groove is slidably mounted with a support slider. The outer side of each support slider is fixedly mounted with a silicone pad. The side of the linkage plate near the guide base is fixedly mounted with multiple extrusion sliders. The inclined surfaces of the multiple extrusion sliders abut against the inclined surfaces of the corresponding support sliders. The inclined surfaces of the multiple extrusion sliders are provided with linkage protrusions, and the inclined surfaces of the multiple support sliders are provided with linkage grooves. The multiple linkage protrusions are slidably mounted in the corresponding linkage grooves. The inclined surfaces of the extrusion sliders abut against the inclined surfaces of the support sliders, converting the axial thrust into the radial expansion force.

[0010] Specifically, a barrier net is fixedly installed on one inner wall of the negative pressure chamber, and a main pipe is fixedly connected to one side of the negative pressure chamber. The end of the main pipe that extends into the negative pressure chamber is located below the barrier net. Branch pipes are fixedly installed on both output ends of the main pipe. Both branch pipes are fixedly connected through the same workbench. The dust generated at the contact point between the cutter head and the grinding wheel is sucked into the negative pressure chamber through the branch pipes and the main pipe. The two branch pipes can suck dust from different angles, expanding the dust suction range and improving collection efficiency.

[0011] Specifically, a storage slot is provided on one side of the negative pressure chamber, which is connected to the negative pressure chamber. A storage drawer is slidably installed on the inner side of the storage slot. The storage drawer is located below the end of the main pipe that extends into the negative pressure chamber.

[0013] Specifically, a positive and negative tooth ball screw is rotatably installed on one side of the inner wall of the adjusting groove. Two threaded sliders are threaded onto the same positive and negative tooth ball screw. Rubber protective sleeves are fitted on the positive and negative tooth ball screws. The two ends of the two rubber protective sleeves are fixedly connected to the corresponding threaded sliders and the inner wall of the adjusting groove, respectively. When the positive and negative tooth ball screws rotate, the two threaded sliders will move synchronously, towards each other or away from each other, thereby changing their distance from the grinding wheel by an equal amount.

[0014] Specifically, a control groove is provided on one side of the adjustment base, and the control groove is connected to the adjustment groove. An adjustment servo motor is fixedly installed on the bottom inner wall of the control groove. The output shaft of the adjustment servo motor is fixedly connected to the forward and reverse toothed ball screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The diamond grinding wheel dressing device of this utility model can provide uniform and strong internal support force by synchronously displacing multiple support sliders inside the grinding wheel and making full contact with the inner wall of the grinding wheel. At the same time, the silicone pad on the support slider increases the friction force and effectively prevents slippage during rotation.

[0033] In this embodiment, a positive and negative tooth ball screw 27 is rotatably installed on one side of the inner wall of the adjusting groove. Two threaded sliders 29 are threadedly sleeved on the same positive and negative tooth ball screw 27. A rubber protective sleeve 28 is sleeved on the positive and negative tooth ball screw 27. The two ends of the two rubber protective sleeves 28 are fixedly connected to the corresponding threaded sliders 29 and the inner wall of the adjusting groove, respectively. When the positive and negative tooth ball screw 27 rotates, the two threaded sliders 29 will move synchronously, towards each other or away from each other, thereby changing their distance from the grinding wheel by an equal amount.

[0034] In this embodiment, a control groove is provided on one side of the adjustment base 25. The control groove is connected to the adjustment groove.

The distance between the two diamond cutter heads 31 can be precisely controlled to adapt to grinding wheels of different widths or requiring specific dressing profiles.

[0035] Working principle: When dressing the grinding wheel, the operator first places the grinding wheel on the guide base 9, and then rotates the linkage head 13 using a hex wrench. The rotation of the linkage head 13 drives the threaded rod 12 to rotate. The threaded rod 12 is threadedly connected to the threaded sleeve 8. When the threaded rod 12 rotates, it moves axially along the internal thread of the threaded sleeve 8, thereby driving the linkage head 13 to move. The linkage head 13 drives the linkage disc 14 to move towards the grinding wheel, thereby driving multiple extrusion sliders 15 to move. The inclined surfaces of the multiple extrusion sliders 15 are respectively connected to the corresponding support sliders 10. When the inclined surfaces abut each other, the multiple extrusion sliders 15 move, respectively driving the corresponding support sliders 10 to move radially along the corresponding guide grooves. The multiple support sliders 10 move outward and abut against the inner wall of the grinding wheel. Silicone pads 11 are fixedly installed on the outer sides of the multiple support sliders 10 to prevent slippage during rotation, thereby achieving stable internal support. Then, the operator starts the cylinder 23. The piston end of the cylinder 23 pushes the outer shell 24 to move, which in turn drives the adjusting base 25 to move closer to the grinding wheel. Then, the operator... Diamond cutter heads 31 are mounted on two tool holders 30. A servo motor 26 drives a forward and reverse threaded ball screw 27 to rotate. The rotation of the ball screw 27 causes two threaded sliders 29 to move closer together, which in turn causes the corresponding tool holders 30 to move closer together, thus synchronously adjusting the distance between the two diamond cutter heads 31 so that they can simultaneously contact the grinding wheel surface. Subsequently, the operator starts the drive servo motor 3 and the exhaust fan 17. The drive servo motor 3 starts, causing the rotating base 7 to rotate, which in turn... As the grinding wheel rotates, two diamond cutting heads 31 cut its surface. Simultaneously, the exhaust fan 17 starts, generating suction that enters the two branch pipes 20 through the main pipe 19. The other ends of the two branch pipes 20 suck up the debris and dust generated during the grinding wheel dressing process. The debris and dust enter the negative pressure chamber 16 through the main pipe 19 and the two branch pipes 20. The barrier net 18 prevents the debris and dust from entering the exhaust fan 17. The debris and dust fall into the storage drawer 21. After the dressing is completed, the staff pulls out the storage drawer 21 and cleans out the debris and dust inside.

[0036] The technological advancements of this invention compared to existing technologies are: it can provide uniform and strong internal support force to the grinding wheel to prevent it from falling off; at the same time, the silicone pad 11 on the support slider 10 increases friction, effectively preventing slippage during rotation; and it can precisely and automatically control the distance between the two diamond cutter heads 31 to ensure that they can contact the grinding wheel surface simultaneously, thereby improving the efficiency and accuracy of dressing.
