[0021] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.
[0022] This utility model provides an overall structural schematic diagram of an embodiment of a clamping device for diamond tool machining, including: Please see Figures 1-5 This embodiment of a diamond tool machining clamping device includes a set of clamping components: The clamping assembly includes a set of clamping bases 100, with a motor 110 snapped into the inner cavity of the clamping bases 100. A clamping box 130 is inserted into the top of the clamping bases 100, and a magnetorheological fluid box 160 is snapped into the inner cavity of the clamping box 130. The magnetorheological fluid box 160 is filled with magnetorheological fluid, which is a semi-liquid, non-Newtonian fluid under normal conditions, but transforms into a solid state when placed in a magnetic field, thus fixing the components inside the magnetorheological fluid box. Multiple clamping rods 170 are linearly and equidistantly inserted into the side wall of the clamping box 130. The ends of the clamping rods 170 penetrate the interior of the clamping box 130 and are finally inserted into the magnetorheological fluid box 160. The interface between the clamping rods 170 and the magnetorheological fluid box 160 needs to be sealed to prevent leakage of the magnetorheological fluid. An electromagnet 190 is inserted into the inner wall of the magnetorheological fluid box 160. Magnet 190 includes an iron core, with an excitation coil sleeved around the outer circumference of the iron core. Electrodes are integrally connected to both ends of the iron core and connected to the circuit through the electrodes. Magnetolite liquid box 160 is made of magnetically conductive material, and the contact surface between electromagnet 190 and magnetolite liquid box 160 should be insulated to prevent short circuits. When electromagnet 190 is energized, it generates a strong magnetic field, causing the magnetolite liquid to instantly turn into a solid state, thereby fixing the end of clamping rod 170. When electromagnet 190 is de-energized, the magnetolite liquid instantly returns to a liquid state, thereby releasing clamping rod 170. Electromagnet 190 is wired to pressure sensor 180. Electromagnet 190 and pressure sensor 180 are connected in parallel in the circuit. A set of protective cover components is provided above the clamping assembly, and a support component is fixed to the bottom of the clamping assembly by screws. The protective cover assembly includes a set of door panel frames 200, which consists of three frame panels and one support plate. The door panel frames 200 are connected and fixed to the support assembly by screws. A top door panel 210 and a set of side door panels 220 are inserted into the inner wall of the door panel frames 200. The top door panel 210 and the two side door panels 220 can be independently extended and retracted laterally. This is to facilitate opening one side of the protective cover assembly to use the clamping assembly, so that the processing surface and the protective surface can be freely selected according to the usage direction of the processing device. The support assembly includes a tabletop 300, with a controller 310 integrally connected to the top of the tabletop 300. The controller (310) is connected to a motor 110, an electromagnet 190, and a pressure sensor 180 via wires. A set of support legs 320 are welded to the bottom of the tabletop 300.
[0023] It is worth noting that, in order for the motor 110 to drive the device, a lead screw 120 is inserted into the inner wall of the motor 110. The motor 110 is connected to one end of the lead screw 120 through the internal rotor. The other end of the lead screw 120 is hinged to the inner wall of the clamp base 100. The threads on the outer circumference of a set of lead screws 120 are all right-handed. Since a set of motors 110 face opposite directions, and the rotor can only rotate in the same direction, only by using threads with the same direction of rotation can the clamping box 130 move in opposite directions. A slide rod 150 is inserted into the inner wall of the clamp base 100. The slide rod 150 is located above the lead screw 120. The slide rod 150 is used to guide the movement direction of the clamping box 130 and provides some support. Therefore, its surface should be polished as smooth as possible to reduce friction and avoid affecting the transmission effect of the motor 110.
[0024] Next, in order to connect the clamping box 130 to the transmission device, specifically, a slider 140 is welded to the bottom of the clamping box 130. This is so that the movement of the slider 140 can drive the clamping box 130 to move. The slider 140 passes through the top of the fixture base 100 and finally fits onto the outer circumference of the slide rod 150 and the lead screw 120. The top of the fixture base 100 has a strip-shaped through hole for the slider 140 to move. This is to keep the top of the fixture base 100 as closed as possible to prevent debris generated during the processing from falling into the interior of the fixture base 100 and affecting the transmission effect of the motor 110. The inner wall of the part where the slider 140 fits onto the lead screw 120 has threads, and the shape and size of the threads match the outer circumference of the lead screw 120.
[0025] Meanwhile, to enable the clamping rod 170 to reset after clamping and to monitor the clamping force, a spring is sleeved on the outer circumference of the clamping rod 170. The spring is snapped into the inside of the clamping plate. When the clamping rod 170 is released, the elastic force generated by the deformation of the spring will drive the clamping rod 170 back to its original position. A pressure sensor 180 is inserted into the center of the side wall of the clamping box 130. During the clamping process, the surface of the workpiece will abut against the sensing end of the pressure sensor 180, so that the pressure sensor 180 can monitor the clamping force in real time and feed it back to the controller 310. When the clamping limit is reached, the pressure sensor 180 will send a signal to the controller 310 to make the motor 110 stop automatically, so as to avoid damage to the workpiece or clamping components due to over-clamping. When the pressure sensor 180 senses that the force reaches the preset value, it will send a signal to the controller 310, and the controller 310 will turn on the electromagnet 190 to connect the circuit, thereby causing the magnetohydrodynamic fluid to change its form and realize the automatic locking of the flexible fixture.
[0026] Furthermore, to make the connection between the top door panel 210 and the side door panel 220 and the door frame 200 more stable, specifically, two insert strips are welded to the top and bottom sides of the top door panel 210, and two insert strips are welded to the inner and outer sides of the side door panel 220. The inner wall of the door frame 200 is provided with slots that match the shape and size of the insert strips. This is to keep the top door panel 210 and the side door panel 220 stable when they extend and retract, and also to provide support. A handle 230 is welded to the top of the top door panel 210 and the outer side of the side door panel 220 to facilitate opening and closing of the top door panel 210 and the side door panel 220. It is worth noting that, specifically, two stop blocks 240 are welded to the upper and lower sides of the top door panel 210. The inner wall of the door panel frame 200 has a slot for the stop blocks 240 to move. This is to prevent the top door panel 210 from detaching from the door panel frame 200. The bottom of the side door panel 220 is welded with a stop block 250 and hinged with two guide wheels 260. The top of the table 300 has a groove for the guide wheels 260 to move. By adding guide wheels 260 to the bottom of the side door panel 220, it is easier to open and close. When the side door panel 220 is opened to the limit, the stop block 250 will abut against the inner wall of the groove, thereby stopping the side door panel 220 and preventing the side door panel 220 from detaching from the door panel frame 200. The side walls of the top door panel 210 and the side door panel 220 are integrally connected with magnetic strips 270. This is so that the top door panel 210 and the side door panel 220 of a set of clamping components can be magnetically connected and fixed by the magnetic strips 270 after they are opened to the limit, thereby forming a closed protective cover assembly.
[0027] Finally, to enable the controller 310 to control the operation of the entire device, a connecting plate 330 is welded between a set of support legs 320, and a base plate is welded to the bottom of the support legs 320. This is to enhance the support effect at the bottom of the device. The controller 310 includes three buttons and a screen. The first button is used to simultaneously control the rotor in a set of motors 110 to rotate counterclockwise, so that the slider 140 will drive the clamping box 130 to move towards the center of the device to clamp the workpiece. The second button is used to simultaneously control the rotor in a set of motors 110 to rotate clockwise, so that the slider 140 will drive the clamping box 130 to move to both sides of the device. The third button is used to control the switch of the circuit where the electromagnet 190 is located. The data collected by the pressure sensor 180 will be transmitted to the controller 310 and displayed on the screen. When the clamping device is triggered to stop, the pressure sensor 180 will transmit information to the controller 310, and then the controller 310 will automatically stop the motor 110.
[0028] In some embodiments, to save costs, the combination of magnetofluid box 160 and electromagnet 190 can be replaced with a pneumatic valve or hydraulic valve structure to fix the clamping rod 130.
[0029] Combination Figures 1-5The specific usage process of the clamping device for diamond tool machining according to this embodiment is as follows: 1. First, weld the connecting plate 330 between a set of support legs 320. Then, weld the base plate to the bottom of the support legs 320. Next, weld the welded device to the bottom of the table 300. Finally, connect the controller 310 to the circuit of the device with wires. In this way, the support component of the device is assembled. Connect the lead screw 120 to the motor 110 and insert them together from the side wall of the clamp base 100. Then, install the slide rod 150 and the slider 140 together inside the clamp base 100 and make the slider 140 fit with the lead screw 120. Insert the electromagnet 190 into the center of the magnetofluid box 160 and install it together inside the clamping box 130. Insert the clamping rod 170 and the pressure sensor 180 into the corresponding positions and insert the clamping rod 170 into the magnetofluid box 160. Finally, weld the clamping box 130 to the top of the slider 140. Finally, connect and fix the clamp base 100 and the table 300 with screws. In this way, the clamping component is also assembled. 2: Install the guide wheel 260 and the second insert 250 at the bottom of the side door panel 220, weld the first insert 240 to the top door panel 210, weld the insert strip and handle 230 to the top positions of the top door panel 210 and the side door panel 220 respectively, install the top door panel 210 and the side door panel 220 in their corresponding positions inside the door panel frame 200, then attach the magnetic strip 270 to the side walls of the top door panel 210 and the side door panel 220, and finally connect and fix the door panel frame 200 to the table 300 with screws. The entire device is now installed. 3. When using the device, press button one on the controller 310 to activate a set of motors 110 and drive a set of sliders 140 towards the center of the device. After the workpiece is clamped and positioned, press button one again to stop the motors 110 or trigger the pressure sensor 180 to stop the device. Then press button three to fix the clamping rod 170 or automatically lock it by setting the pressure sensor 180 to the pre-set force value. In this way, the workpiece is firmly clamped between the two clamping boxes 130. Finally, selectively close the protective cover assembly according to the direction of the machining tool operation, leaving only one side open as the machining port. After machining is completed, press button three to de-energize the electromagnet 190 and release the clamping rod 170. Then press button two to activate a set of motors 110 and drive a set of sliders 140 to move to both sides, so that the workpiece can be removed. Then press button two again to stop the motors 110. Finally, close the protective cover assembly. When the device is not in use, the protective cover assembly can also be opened to block external dust and debris.
