Description

Technical Field

[0001] This application relates to the field of electrolytic grinding, and more specifically, to a floating device for an electrolytic grinding head with a force control sensor. Background Technology

[0002] Electrolytic grinding equipment is a composite processing device combining electrolytic machining and mechanical grinding. It achieves efficient and precise material removal through the synergistic effect of electrochemical action and mechanical grinding. The workpiece is connected to the anode of a DC power supply, and the conductive grinding wheel is connected to the cathode. Electrolyte is injected into a very small gap. Under the action of an electric field, the metal on the workpiece surface undergoes anodic dissolution, forming an oxide or hydroxide film (anodic passivation film). The abrasive grains of the rotating grinding wheel scrape away the anodic passivation film, exposing a new metal surface for continued electrolysis. This cycle is repeated to achieve material removal.

[0003] In existing technologies, by setting up pressure sensors and floating components, the contact force between the grinding head and the workpiece can be detected by the pressure sensors. The feedback system, in conjunction with the floating components, drives the grinding head to move, thereby adjusting the contact force and making the grinding of the workpiece more precise.

[0004] However, the existing floating device for electrolytic grinding heads with force control sensors still has the following shortcomings during use: the existing pressure sensor has certain deficiencies in the internal protection device of the electrolytic grinding device. During use, since the pressure sensor and the grinding head are always fixedly connected, when the contact force between the grinding head and the workpiece changes suddenly (such as a hard workpiece suddenly cutting in), it causes an instantaneous impact on the pressure sensor, resulting in damage to the pressure sensor. Utility Model Content

[0005] To overcome the above deficiencies, this application provides a floating device for an electrolytic grinding head with a force control sensor, which aims to improve the problem that the pressure sensor is always fixedly connected to the grinding head, and when the contact force between the grinding head and the workpiece changes suddenly, it causes instantaneous impact on the pressure sensor, resulting in damage to the pressure sensor.

[0006] This application provides a floating device for an electrolytic grinding head with a force control sensor, including an electrolytic grinding device, a grinding head body disposed inside the electrolytic grinding device, a floating component for moving the grinding head disposed inside the electrolytic grinding device, a moving part connected to the output end of the floating component, a spraying component for spraying electrolyte disposed inside the electrolytic grinding device, a pressure sensor disposed inside the electrolytic grinding device, an adjusting mechanism for adjusting the position of the pressure sensor disposed inside the electrolytic grinding device, and a protective mechanism for protecting the pressure sensor disposed inside the electrolytic grinding device.

[0007] The adjustment mechanism includes a mounting component connected to the outer surface of the grinding head body. A first slot and a second slot are provided on one side of the mounting component.

[0008] In one specific implementation, a third electric telescopic rod is connected to one side of the movable component, and a first locking member is connected to the telescopic end of the third electric telescopic rod. The first locking member is movably inserted into the inside of a first locking slot.

[0009] In the above implementation process, by setting the third electric telescopic rod, the first locking member can be moved by controlling the third electric telescopic rod, and the first locking member can be inserted into the first locking slot or removed from the first locking slot.

[0010] In one specific implementation, a housing is connected to one side of the movable component, a motor is connected to one side of the housing, the output shaft of the motor passes through the housing and is connected to a first rotating shaft, the other end of the first rotating shaft is rotatably connected inside the housing, and the first rotating shaft is connected to the mounting end of the pressure sensor.

[0011] In the above implementation process, by setting up the motor, the output shaft of the motor can be controlled to rotate, thereby driving the first rotating shaft to rotate inside the housing.

[0012] In one specific implementation, the first rotating shaft is connected to the mounting end of the pressure sensor, and one end of the pressure sensor is connected to a second clip, which is movably inserted into the inside of a second slot.

[0013] In the above implementation process, by setting the second card, the pressure sensor can be driven to rotate when the first rotating shaft rotates, so that the second card can be inserted into the second card slot or disengaged from the second card slot.

[0014] In one specific implementation, a first fixing groove is provided on one side of the first card, and a second fixing groove is provided on one side of the second card.

[0015] In the above implementation process, by setting the first fixing slot and the second fixing slot, the first card can be fixed inside the first card slot by the first fixing slot, and the second card can be fixed inside the second card slot by the second fixing slot.

[0016] In one specific implementation, a T-shaped component is connected to one side of the mounting component, and a first electric telescopic rod and a second electric telescopic rod are connected to one side of the T-shaped component. The telescopic end of the first electric telescopic rod is connected to a first fixing component, which is movably inserted into the interior of a first fixing groove. The telescopic end of the second electric telescopic rod is connected to a second fixing component, which is movably inserted into the interior of a second fixing groove.

[0017] In the above implementation process, by setting the T-shaped component, the first fixing component can be inserted into the first fixing groove by controlling the first electric telescopic rod, and the first locking component can be fixed inside the first locking groove. By controlling the second electric telescopic rod, the second fixing component can be inserted into the second fixing groove, and the second locking component can be fixed inside the second locking groove. When detecting the contact force between the workpiece and the grinding head, the second locking component can be fixed inside the second locking groove, and the first locking component can be disengaged from the first locking groove. The grinding head and the moving component are connected by a pressure sensor, and the contact force can be detected. After the detection is completed, the first locking component is fixed inside the first locking groove, and the second locking component is disengaged from the second locking groove. The grinding head and the moving component are connected by a third electric telescopic rod, which can prevent sudden changes in the contact force between the grinding head and the workpiece during processing, which could damage the pressure sensor.

[0018] In one specific implementation, the protective mechanism includes a second rotating shaft rotatably connected to the bottom of the housing, an L-shaped baffle connected to the outer surface of the second rotating shaft, two sets of first magnetic components embedded in the top of the L-shaped baffle, and a limiting component connected to the bottom of the housing.

[0019] In the above implementation process, by setting the L-shaped baffle, when the second clamp is driven by the motor to rotate outward from the housing, the second clamp will drive the L-shaped baffle to rotate around the second rotating shaft as the center. By setting the limiting component, the L-shaped baffle can only rotate 90 degrees.

[0020] In one specific implementation, the interior of the housing is connected to two sets of vertical plates, and one side of each vertical plate is embedded with two sets of second magnetic elements. The side of the second magnetic element closest to the first magnetic element can attract the top of the first magnetic element.

[0021] In the above implementation process, by setting the second magnetic component, when the second card rotates into the housing, the second card will drive the L-shaped baffle to rotate in the opposite direction around the second rotating shaft, so that the first magnetic component gradually approaches the second magnetic component. Then, through the attraction between the first magnetic component and the second magnetic component, the second baffle blocks part of the opening of the housing.

[0022] In one specific implementation, a third rotating shaft is rotatably connected to the top of the housing, a rotating component is connected to the outer surface of the third rotating shaft, and a first baffle is connected to one side of the rotating component.

[0023] In the above implementation process, by setting the first baffle, when the second card rotates outward from the housing, the first baffle is driven to rotate around the third rotating shaft as the center.

[0024] In one specific implementation, both ends of the rotating component are connected to torsion springs, and the other end of the torsion springs is connected to the inner wall of the housing.

[0025] In the above implementation process, by setting the torsion spring, when the second clip rotates into the housing, the torsion spring releases elastic potential energy, causing the first baffle to reset and partially blocking the opening of the housing. Through the first baffle and the L-shaped baffle, the opening of the housing is completely blocked, preventing the electrolyte from entering the interior of the housing, causing corrosion to the pressure sensor, and affecting the accuracy of the pressure sensor.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting the adjustment mechanism and the protective mechanism, when detecting the contact force between the workpiece and the grinding head, the second clamping member is fixed inside the second slot, and the first clamping member is disengaged from the first slot. The grinding head and the moving part are connected through the pressure sensor, and the contact force can be detected. After the detection is completed, the first clamping member is fixed inside the first slot, and the second clamping member is disengaged from the second slot. The grinding head and the moving part are connected through the third electric telescopic rod. This can prevent the sudden change in the contact force between the grinding head and the workpiece during processing, which could damage the pressure sensor. Furthermore, when the pressure sensor does not need to be detected, it is located inside the housing. The opening of the housing is completely blocked by the first baffle and the L-shaped baffle, preventing the electrolyte from entering the housing and corroding the pressure sensor, thus affecting the accuracy of the pressure sensor. This solves the problem that the pressure sensor is always fixedly connected to the grinding head, and when the contact force between the grinding head and the workpiece changes suddenly, it causes a momentary impact on the pressure sensor, resulting in damage to the pressure sensor.

The floating component 5 and the spraying component 4 are existing technologies and will not be described in detail here.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The adjustment mechanism 2 includes a mounting component 201, which is connected to the outer surface of the grinding head body 7.

The telescopic end of the third electric telescopic rod 2013 is connected to a first locking component 209. The first locking component 209 is movably inserted into the first locking slot 202. By configuring the third electric telescopic rod 2013, the first locking component 209 can be moved by controlling the third electric telescopic rod 2013, allowing the first locking component 209 to be inserted into the first locking slot 202 or disengaged from the first locking slot 202.

[0042] In a specific configuration, a housing 2016 is connected to one side of the movable component 6, and a motor 2014 is connected to one side of the housing 2016. The output shaft of the motor 2014 passes through the housing 2016 and is connected to a first rotating shaft 2015. The other end of the first rotating shaft 2015 is rotatably connected inside the housing 2016. The first rotating shaft 2015 is connected to the mounting end of the pressure sensor 8. By configuring the motor 2014, the first rotating shaft 2015 can be rotated inside the housing 2016 by controlling the rotation of the output shaft of the motor 2014.

[0043] In a specific configuration, the first rotating shaft 2015 is connected to the mounting end of the pressure sensor 8. One end of the pressure sensor 8 is connected to a second clip 2012, which is movably inserted into the interior of the second slot 203. The second clip 2012 allows the pressure sensor 8 to rotate when the first rotating shaft 2015 rotates, thus inserting the second clip 2012 into the interior of the second slot 203 or disengaging the second clip 2012 from the second slot 203.

[0044] In a specific configuration, a first fixing groove 2010 is provided on one side of the first card 209, and a second fixing groove 2011 is provided on one side of the second card 2012. The first fixing groove 2010 and the second fixing groove 2011 are used to fix the first card 209 inside the first card slot 202 through the first fixing groove 2010, and fix the second card 2012 inside the second card slot 203 through the second fixing groove 2011.

[0045] In a specific configuration, a T-shaped component 204 is connected to one side of the mounting component 201, and a first electric telescopic rod 205 and a second electric telescopic rod 207 are connected to one side of the T-shaped component 204. The telescopic end of the first electric telescopic rod 205 is connected to a first fixing component 206, which is movably inserted into the first fixing groove 2010. The telescopic end of the second electric telescopic rod 207 is connected to a second fixing component 208, which is movably inserted into the second fixing groove 2011. Through the T-shaped component 204, by controlling the first electric telescopic rod 205, the first fixing component 206 can be inserted into the first fixing groove 2010, and the first locking component 209 can be fixed inside the first locking groove 202. By controlling the second electric telescopic rod 207... 07. Insert the second fixing member 208 into the second fixing groove 2011 and fix the second clamping member 2012 into the second clamping groove 203. When detecting the contact force between the workpiece and the grinding head, fix the second clamping member 2012 into the second clamping groove 203, so that the first clamping member 209 is disengaged from the first clamping groove 202. Connect the grinding head and the moving member 6 through the pressure sensor 8 to detect the contact force. After the detection is completed, fix the first clamping member 209 into the first clamping groove 202 and disengage the second clamping member 2012 from the second clamping groove 203. Connect the grinding head and the moving member 6 through the third electric telescopic rod 2013 to prevent sudden changes in the contact force between the grinding head and the workpiece during processing, which could damage the pressure sensor 8.

[0046] In a specific configuration, the protective mechanism 3 includes a second rotating shaft 305, which is rotatably connected to the bottom of the housing 2016. An L-shaped baffle 303 is connected to the outer surface of the second rotating shaft 305. Two sets of first magnetic components 306 are embedded in the top of the L-shaped baffle 303. A limiting component 304 is connected to the bottom of the housing 2016. By setting the L-shaped baffle 303, when the second locking component 2012 rotates outward from the housing 2016 under the drive of the motor 2014, the second locking component 2012 will drive the L-shaped baffle 303 to rotate around the second rotating shaft 305. By setting the limiting component 304, the L-shaped baffle 303 can only rotate 90 degrees.

[0047] In the specific configuration, two sets of vertical plates 307 are connected inside the housing 2016. Two sets of second magnetic components 308 are embedded in one side of the vertical plate 307. The side of the second magnetic component 308 that is close to the first magnetic component 306 can attract the top of the first magnetic component 306. In this configuration, when the second locking piece 2012 rotates into the housing 2016, the second locking piece 2012 will drive the L-shaped baffle 303 to rotate in the opposite direction around the second rotating shaft 305, so that the first magnetic component 306 gradually approaches the second magnetic component 308. Then, through the attraction between the first magnetic component 306 and the second magnetic component 308, the second baffle blocks part of the opening of the housing 2016.

[0048] In a specific configuration, a third rotating shaft 309 is rotatably connected to the top of the housing 2016. A rotating component 301 is connected to the outer surface of the third rotating shaft 309. A first baffle 302 is connected to one side of the rotating component 301. The first baffle 302 is configured such that when the second locking component 2012 rotates outward from the housing 2016, the first baffle 302 rotates around the third rotating shaft 309.

[0049] In the specific configuration, both ends of the rotating component 301 are connected to torsion springs 3010, and the other end of the torsion springs 3010 is connected to the inner wall of the housing 2016. The torsion springs 3010 release elastic potential energy when the second clamping component 2012 rotates into the housing 2016, causing the first baffle 302 to reset and partially block the opening of the housing 2016. The opening of the housing 2016 is completely blocked by the first baffle 302 and the L-shaped baffle 303, preventing the electrolyte from entering the interior of the housing 2016 and causing corrosion to the pressure sensor 8, thus affecting the accuracy of the pressure sensor 8.

[0050] The working principle of the electrolytic grinding head floating device with force control sensor is as follows: When using the electrolytic grinding head floating device with force control sensor, when detecting the contact force between the workpiece and the grinding head, the second clamping member 2012 is rotated by controlling the motor 2014 to insert the second clamping member 2012 into the second clamping slot 203. The second electric telescopic rod 207 is controlled to insert the second fixing member 208 into the second fixing slot 2011, so that the second clamping member 2012 is fixed inside the second clamping slot 203, and the first clamping member 209 is disengaged from the first clamping slot 202. The grinding head and the moving member 6 are connected by the pressure sensor 8, and the contact force can be detected. After the detection is completed, the first clamping member 209 is moved by controlling the third electric telescopic rod 2013 to insert the first clamping member 209 into the first clamping slot 202. Then, the first electric telescopic rod 205 is controlled. The first fixing member 206 is inserted into the first fixing groove 2010, the first locking member 209 is fixed inside the first locking groove 202, and the second locking member 2012 is disengaged from the second locking groove 203. The grinding head and the moving member 6 are connected by the third electric telescopic rod 2013. This can prevent the sudden change in the contact force between the grinding head and the workpiece during processing, which could damage the pressure sensor 8. When the pressure sensor 8 does not need to be detected, it is located inside the housing 2016. The opening of the housing 2016 is completely blocked by the first baffle 302 and the L-shaped baffle 303, preventing the electrolyte from entering the interior of the housing 2016 and corroding the pressure sensor 8, thus affecting the accuracy of the pressure sensor 8. This solves the problem that the pressure sensor 8 is always fixedly connected to the grinding head, and when the contact force between the grinding head and the workpiece changes suddenly, it causes a momentary impact on the pressure sensor 8, which can damage the pressure sensor 8.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
