Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and in particular to an intelligently controlled grinding equipment. Background Art

[0002] Grinding is essential for parts processing. There are many different methods of grinding, among which centerless grinding is the most widely used. Centerless grinding uses a grinding wheel that rotates at high speed to grind, while a guide wheel rotates in the same direction at a slower speed, thus driving the workpiece to rotate and feed in a circular motion, gradually rounding the workpiece.

[0003] If the roundness of the workpiece is not enough during grinding, the workpiece will jump, and when the roundness difference of the workpiece is large, the workpiece may even get stuck. The jumping of the workpiece during centerless grinding refers to the workpiece continuously and slightly jumping up and down on the surface of the support plate and making a knocking sound. The result of this jumping will cause errors in the overall shape accuracy and surface roughness of the workpiece after grinding. The stuck workpiece means that the workpiece will be driven downward by the grinding wheel, which will have an adverse effect on the subsequent grinding of the grinding wheel and the workpiece. Summary of the Invention

[0004] The present invention provides an intelligently controlled grinding device to solve the problem that when the existing grinding device is in use, the jumping and jamming of the workpiece will have a significant impact on the grinding quality and the precision of the workpiece.

[0006] Furthermore, the flow channel includes a main channel and multiple branch channels. The main channel is arranged along the second direction. The multiple branch channels are evenly distributed on the main channel along the second direction. The multiple branch channels are all connected to the main channel, and the branch channels are wing-shaped.

[0007] Furthermore, the upper and lower ends of the slider are connected, and the liquid is a coolant.

[0008] Furthermore, a liquid inlet is provided on the supporting plate, and the liquid inlet is communicated with the lower end of the flow channel.

[0009] Furthermore, the flow channel and the slider are both provided in plurality, and the plurality of flow channels and the plurality of sliders are provided in one-to-one correspondence.

[0010] Furthermore, a plurality of liquid inlets are provided, and the plurality of liquid inlets are arranged in a one-to-one correspondence with the plurality of flow channels.

[0011] Furthermore, a first support and a second support are installed on the frame, the first support is fixed to the frame, and the second support can be slidably installed on the frame along a third direction, the third direction is horizontal and perpendicular to the first direction, the grinding wheel is rotatably installed on the first support, and the guide wheel is rotatably installed on the second support and can slide in the third direction with the second support.

A second driving member is provided on the second support, and the second driving member is used to drive the guide wheel to rotate around its own axis.

[0014] Furthermore, the grinding wheel is made of diamond; the guide wheel is made of nylon.

[0015] The beneficial effects of the present invention are as follows: an intelligently controlled grinding device of the present invention sets a flow channel in the support plate. When the workpiece vibrates, the vibration of the workpiece will cause the slider to slide slightly in the flow channel, and the reflux speed is relatively slow. Since the flow channel is a Tesla valve structure, and the resistance of the liquid when flowing from bottom to top in the flow channel is less than the resistance of the liquid when flowing from top to bottom in the flow channel, when the slider tends to move from top to bottom in the flow channel, the movement of the liquid from top to bottom will be hindered, thereby hindering the movement of the slider, and the slider will be reset under the drive of the continuously upward flowing liquid. The resistance adjustment of the liquid flow is realized through the special Tesla valve structure of the flow channel, thereby having the effect of slowing down the vibration of the workpiece. When the workpiece is clamped, it will move downward under the drive of the grinding wheel, squeezing the slider, causing the slider to move downward in the flow channel and the reflux speed to become faster. At this time, the resistance of the liquid flowing from top to bottom in the flow channel is relatively large. This resistance can effectively slow down the flow of liquid, thereby limiting the downward movement of the slider. After being ground, the clamping position will be reset under the drive of the continuously upward flowing liquid, weakening the adverse effects of the workpiece clamping on the grinding wheel and the workpiece, improving the stability of grinding, and making the vibration of the workpiece and the adjustment of the clamping position more intelligent and controllable.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] An embodiment of an intelligently controlled grinding device of the present invention is as follows Figures 1 to 8 shown.

[0028] An intelligently controlled grinding device for grinding a workpiece 500 includes a frame 100, a grinding wheel 200, a guide wheel 300, and a support assembly 400. The grinding wheel 200 is mounted on the frame 100 so as to be rotatable about its own axis. The direction of the rotation axis of the grinding wheel 200 is referred to as a first direction, which is a horizontal direction. The guide wheel 300 is arranged along the first direction and is mounted on the frame 100 so as to be rotatable about its own axis. The grinding wheel 200 and the guide wheel 300 rotate in the same direction. The support assembly 400 is mounted on the frame 100 and is located between the grinding wheel 200 and the guide wheel 300. The support assembly 400 includes a support plate 410 and a slider 420. The support plate 410 is fixedly mounted on the frame 100. A flow channel 430 is defined within the support plate 410 and arranged along a second direction within the support plate 410, which is the vertical direction. The flow channel 430 has a Tesla valve structure, and liquid always flows from bottom to top within the flow channel 430. The resistance to liquid flow from bottom to top within the flow channel 430 is less than the resistance to liquid flow from top to bottom within the flow channel 430. The slider 420 is mounted on the upper end of the flow channel 430 so as to be able to slide up and down, and the slider 420 blocks the upper end of the flow channel 430. The workpiece 500 is located at the upper end of the slider 420, supported by the slider 420 and in contact with the grinding wheel 200 and the guide wheel 300.

[0029] The center line of the grinding wheel 200 and the guide wheel 300 are coplanar, and the center of the workpiece 500 is higher than the center line of the grinding wheel 200 and the guide wheel 300. This makes the contact points between the workpiece 500 and the grinding wheel 200 and the guide wheel 300 asymmetrical, so that certain raised surfaces on the workpiece 500 can be gradually rounded during multiple rotations.

[0030] This embodiment provides a flow channel 430 in the support plate 410 . When in use, the grinding wheel 200 and the guide wheel 300 are driven to rotate around their own axes to grind the workpiece 500 , while liquid is introduced into the flow channel 430 to flow from bottom to top.

[0031] When the workpiece 500 vibrates, the vibration of the workpiece 500 will cause the slider 420 to slide slightly in the flow channel 430, and the reflux speed is relatively slow. Since the flow channel 430 is a Tesla valve structure, and the resistance of the liquid when flowing from bottom to top in the flow channel 430 is less than the resistance of the liquid when flowing from top to bottom in the flow channel 430, when the slider 420 tends to move from top to bottom in the flow channel 430, the movement of the liquid from top to bottom will be hindered, thereby hindering the movement of the slider 420, and the slider 420 will be reset under the drive of the continuously upward flowing liquid, and the resistance of the liquid flow is adjusted through the special Tesla valve structure of the flow channel 430, thereby having the effect of slowing down the vibration of the workpiece 500.

[0032] When the workpiece 500 is positioned, the workpiece 500 will move downward under the drive of the grinding wheel 200, squeezing the slider 420, causing the slider 420 to move downward in the flow channel 430, and the reflux speed will become faster. At this time, the resistance of the liquid flowing from top to bottom in the flow channel 430 is relatively large. This resistance can effectively slow down the flow of the liquid, thereby limiting the downward movement of the slider 420, and the position will be reset after being ground under the drive of the continuously upward flowing liquid, weakening the adverse effects of the workpiece 500 positioning on the grinding wheel 200 and the workpiece 500, improving the stability of grinding, and making the vibration of the workpiece 500 and the positioning adjustment more intelligent and controllable.

[0033] In this embodiment, the flow channel 430 includes a main channel 431 and multiple branch channels 432. The main channel 431 is arranged along the second direction. The multiple branch channels 432 are evenly distributed along the second direction on the main channel 431, and the multiple branch channels 432 are all connected to the main channel 431. The branch channels 432 are wing-shaped.

[0034] See attached Figure 8 As shown, by setting the direction of the flow channel 430, when the liquid flows from bottom to top, it can bypass all the branch channels 432 and flow unimpeded from bottom to top, and obtain an acceleration effect due to the flow pressure. However, when the liquid flows from top to bottom, the liquid will flow back due to the obstruction of the branch channels 432. The backflow will cause a flow obstruction effect and hinder the flow of the liquid. In other words, the resistance of the liquid when flowing from bottom to top in the flow channel 430 is less than the resistance of the liquid when flowing from top to bottom in the flow channel 430.

[0035] Specifically, a liquid inlet 411 is formed on the support plate 410 , and the liquid inlet 411 is communicated with the lower end of the flow channel 430 . Liquid can be transported into the flow channel 430 through the liquid inlet 411 .

[0036] Specifically, the grinding wheel 200 is made of diamond, and the guide wheel 300 is made of nylon.

[0037] In this embodiment, the upper and lower ends of the slider 420 are connected, and the liquid is a coolant.

[0038] By delivering the coolant into the flow channel 430 , the coolant can flow through the slider 420 to the surface of the workpiece 500 during grinding, thereby dissipating heat from the workpiece 500 .

[0039] In this embodiment, a first support 110 and a second support 120 are installed on the frame 100. The first support 110 is fixedly connected to the frame 100, and the second support 120 can be slidably installed on the frame 100 along a third direction, which is horizontal and perpendicular to the first direction. The grinding wheel 200 is rotatably installed on the first support 110, and the guide wheel 300 is rotatably installed on the second support 120.

[0040] Specifically, the frame 100 is provided with a screw-nut mechanism, which is used to drive the second support 120 to slide along the third direction on the frame 100. The screw-nut mechanism includes a screw and a nut. The screw is arranged along the third direction and is driven by a motor so that the screw is mounted on the frame 100 so as to be rotatable about its own axis. A guide rail is provided on the frame 100, and the nut is slidably engaged with the guide rail and is threadedly engaged with the screw. Therefore, when the screw rotates about the third direction, the nut can slide in the third direction. The second support 120 is mounted on the nut and can slide along with the nut.

[0041] A first driving member is provided on the first support 110 for driving the grinding wheel 200 to rotate about its own axis, and a second driving member is provided on the second support 120 for driving the guide wheel 300 to rotate about its own axis. Both the first driving member and the second driving member are motors.

[0042] In this embodiment, the flow channel 430 and the slider 420 are both provided in plurality, and the plurality of flow channels 430 and the plurality of sliders 420 are provided in a one-to-one correspondence.

[0043] By providing a plurality of flow channels 430 and a plurality of sliders 420 , the sensitivity of each flow channel 430 during the grinding of the workpiece 500 is improved, and the stability and intelligence of the workpiece 500 during the grinding are further improved.

[0044] Furthermore, a plurality of liquid inlets 411 are provided, and the plurality of liquid inlets 411 are arranged in a one-to-one correspondence with the plurality of flow channels 430 .

[0045] By providing a plurality of liquid inlets 411 , the number of flow channels 430 that require liquid inlet can be adjusted according to the length of the workpiece 500 during use, thereby avoiding waste of coolant.

[0046] In combination with the above embodiment, the specific working process is as follows:

[0047] During use, the workpiece 500 to be ground is placed on the slider 420 , and the second support 120 is driven to move the guide wheel 300 , so that the workpiece 500 is in contact with the grinding wheel 200 and the guide wheel 300 at the same time.

[0048] The first and second driving members are then activated. The first driving member rotates the grinding wheel 200 about its axis, while the second driving member rotates the guide wheel 300 about its axis, grinding the workpiece 500. Simultaneously, coolant is introduced into the flow channel 430 from bottom to top. During grinding, the coolant flows through the slider 420 to the surface of the workpiece 500, dissipating heat from the workpiece 500.

[0049] When the workpiece 500 vibrates, the vibration of the workpiece 500 will cause the slider 420 to slide slightly in the flow channel 430, and the reflux speed is relatively slow. Since the flow channel 430 is a Tesla valve structure, and the resistance of the liquid when flowing from bottom to top in the flow channel 430 is less than the resistance of the liquid when flowing from top to bottom in the flow channel 430, when the slider 420 tends to move from top to bottom in the flow channel 430, the movement of the liquid from top to bottom will be hindered, thereby hindering the movement of the slider 420, and the slider 420 will be reset under the drive of the continuously upward flowing liquid, and the resistance of the liquid flow is adjusted through the special Tesla valve structure of the flow channel 430, thereby having the effect of slowing down the vibration of the workpiece 500.

[0050] When the workpiece 500 is positioned, the workpiece 500 will move downward under the drive of the grinding wheel 200, squeezing the slider 420, causing the slider 420 to move downward in the flow channel 430, and the reflux speed will become faster. At this time, the resistance of the liquid flowing from top to bottom in the flow channel 430 is relatively large. This resistance can effectively slow down the flow of the liquid, thereby limiting the downward movement of the slider 420, and the position will be reset after being ground under the drive of the continuously upward flowing liquid, thereby weakening the adverse effects of the workpiece 500 positioning on the grinding wheel 200 and the workpiece 500, and improving the stability and intelligence of the grinding.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
