Description

Technical Field

[0001] The invention relates to the technical field of hardware parts production, in particular to a hardware parts grinding machine tool and a grinding assembly thereof. Background Art

[0002] A grinder is a machine that grinds the surface of a workpiece using a tool coated with or embedded with abrasives. It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in workpieces. It is used for single-sided grinding and polishing of materials.

[0003] The Chinese invention patent with application number 201611154846.6 proposes a plane grinding machine, which includes: a base; a first rotating unit, which is arranged on the base, and the first rotating unit has a rotating shaft; a lower positioning plate, which is connected to the rotating shaft; an ultrasonic unit, which is connected to the lower positioning plate, and the ultrasonic unit makes the lower positioning plate vibrate up and down; a second rotating unit, which is arranged on the base; an upper positioning plate, which is connected to the second rotating unit, and the upper positioning plate can be moved to the corresponding lower positioning plate. When grinding the object to be ground, the ultrasonic unit controls the lower positioning plate to vibrate, so that the object to be ground as a whole vibrates accordingly, which can increase the grinding speed of the object to be ground.

[0004] However, in the prior art, when the grinding disc is in a state of grinding for a long time, since the inner diameter of the grinding disc is small and the outer diameter is large, the inner friction circles are more and the outer friction circles are less, the inner disc surface is severely worn and lower than the outer disc surface, resulting in the disc surface being low in the center and high around, resulting in uneven grinding force of hardware parts and affecting the grinding quality; in addition, common stop arms are fixed on the working platform and cannot be adjusted, and can only adapt to hardware parts within a certain size range. Therefore, when it is necessary to grind hardware parts with a larger diameter, the stop arm needs to be replaced, and the replacement procedure is relatively cumbersome, affecting the grinding efficiency; when the hardware parts are fixed, the fixing depth is inconsistent, so that when grinding, the holes for fixing the hardware parts are severely worn, resulting in shaking of the hardware parts during subsequent grinding, resulting in increased scratches.

[0021] Technical effects and advantages of the present invention:

[0022] 1.

[0023] 2. In the present invention, the clamping assembly is stabilized by setting a limit assembly so that it can maintain stable rotation and grinding on the grinding disc. The limit assembly can also adjust the inclination angle of the clamping assembly to make it parallel to the surface of the grinding disc, thereby ensuring that the pressure of the clamping assembly on the hardware part body is uniform, thereby ensuring uniform grinding force; by setting a blocking assembly, the bending degree of the blocking arm can be adjusted to adapt to hardware parts of different sizes, thereby avoiding the impact of replacement of the blocking arm on the grinding efficiency.

[0024] 3. In the present invention, a detection component is used to detect whether the diameter of the current retaining ring is too large or too small relative to the bending degree of the elastic retaining arm. The bending degree of the elastic retaining arm is adjusted by adjusting the left and right movement of the auxiliary roller at the right end to ensure that the elastic retaining arm can use retaining rings of different sizes and can grind hardware parts of different sizes, thereby avoiding frequent replacement of retaining arms of different sizes that affects the grinding efficiency.

[0025] 4. In the present invention, a limiting assembly is provided to limit the clamping assembly, so that the clamping assembly can maintain stable rotation and grinding on the grinding disc, and prevent the clamping assembly from flying out of the grinding surface of the grinding disc under high-speed rotation and grinding.

[0026] 5. In the present invention, by detecting the change in the compression amount of the auxiliary spring in real time, it is determined whether the grinding surface of the current grinding disc is tilted, and then the tangent value of the tilt angle is obtained through the difference between the maximum and minimum deformation amounts of the auxiliary springs combined with the distance between the two auxiliary springs, thereby obtaining the angle of the tilt angle, and the measurement method is automated to improve the grinding efficiency; by detecting the stretching amount of the telescopic spring in real time, it is determined whether the current retaining ring is offset, and the blocking assembly is driven to rotate by the positioning motor, thereby driving the retaining ring to move and adjust its position on the grinding disc, ensuring that the retaining ring is completely located on the grinding disc for effective grinding, thereby ensuring the grinding efficiency.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] In order to solve the problem that the grinding disk 2 has a low center and high surroundings, resulting in uneven grinding force on hardware parts, affecting the grinding quality, being unable to adapt to the grinding of hardware parts of larger sizes, and inconsistent fixing depths of hardware parts, which causes serious wear on the holes for fixing the hardware parts during grinding, resulting in shaking of the hardware parts during subsequent grinding, leading to increased scratches, embodiment 1 is proposed.

[0039] Embodiment 1:

[0040] When grinding the hardware part body 12, a pressing component with a certain weight needs to be placed above the hardware part body 12 so that the hardware part body 12 fits tightly with the grinding disc 2, which facilitates the rotation and grinding of the hardware part body 12 by the grinding disc 2. Figures 1 to 3 As shown, the present invention discloses a grinding assembly, including a grinding disc 2, a clamping assembly 6 is placed on the grinding disc 2, the clamping assembly 6 includes a counterweight 601, a retaining ring 608 is clamped on the outer side of the counterweight 601, a clamping strip 602 is arranged on the side of the counterweight 601, a clamping groove is arranged on the inner side of the retaining ring 608, the clamping strip 602 is slidably connected in the clamping groove, the clamping strip 602 is clamped in the clamping groove and fixed with the retaining ring 608, a gasket 607 is placed inside the retaining ring 608, and a hardware part body 12 is uniformly clamped on the gasket 607 The gasket 607 is used to ensure the stable distance between the hardware parts body 12, and is generally made of silicone or plastic. The gasket 607 is evenly provided with holes that match the shape of the outer edge of the hardware parts body 12. The hardware parts body 12 can be tightly stuck in the holes. The diameter of the gasket 607 is slightly smaller than the retaining ring 608, so that it can be smoothly placed within the inner diameter range of the retaining ring 608. A limiting shaft 609 is fixedly provided on the top surface of the counterweight block 601, and a sleeve 610 is fixedly provided on the top surface of the limiting shaft 609.

[0041] When in use, the hardware part body 12 is snapped into the holes of the gasket 607 in turn, placed in the retaining ring 608, and then the clip 602 on the counterweight block 601 is aligned with the slot and slid along the slot so that the counterweight block 601 is pressed on the hardware part body 12. Subsequently, the retaining ring 608 is intercepted by the blocking component 5, and the rotational friction of the grinding disc 2 is cooperated to make the clamping component 6 drive the hardware part body 12 to rotate, thereby completing the grinding of the hardware part body 12.

[0042] When the hardware part body 12 is inserted into the gasket 607, the insertion depth of the hardware part body 12 may be inconsistent, resulting in the gasket 607 being uneven when the hardware part body 12 and the gasket 607 are inserted into the grinding disc 2. According to the inconsistent insertion depth, the gasket 607 may be partially lifted or rolled down, which will cause the side of the hole on the gasket 607 to not fit the surface of the hardware part body 12, resulting in severe wear of the hole during the subsequent grinding process, and the hardware part body 12 cannot be tightly clamped subsequently, which will cause the hardware part body 12 to shake in the hole during grinding, resulting in multiple scratches on its grinding surface, affecting the grinding effect.

[0043] In order to solve the above technical problems, an auxiliary spring 606 and a spherical block 605 are arranged to press the gasket 607 so that the gasket 607 can maintain a flat state. The side of the counterweight block 601 is evenly provided with a fixing plate 603, and a lifting column 604 is movably arranged on the central axis of the fixing plate 603. A spherical block 605 is fixedly arranged on one end of the lifting column 604 away from the fixing plate 603. An auxiliary spring 606 is arranged on the outside of the lifting column 604, one end of the auxiliary spring 606 is fixedly connected to the fixing plate 603, and the other end is fixedly connected to the spherical block 605. A blind hole corresponding to the lifting column 604 is opened on the counterweight block 601, and one end of the lifting column 604 extends into the blind hole and rises and falls along the blind hole.

[0044] After the counterweight block 601 is pressed onto the hardware part body 12, the spherical block 605 presses against the gasket 607, the auxiliary spring 606 is compressed, and the lifting column 604 rises along the blind hole. With the assistance of the elastic force of the auxiliary spring 606, the spherical block 605 presses the gasket 607, so that the position of the raised gasket 607 or the position of the rolled-down gasket 607 is pressed flat, so that the side of the hole fits tightly with the surface of the hardware part body 12.

[0045] By setting the auxiliary spring 606 and the spherical block 605, while the counterweight block 601 presses the hardware part body 12, the elastic force of the auxiliary spring 606 presses the gasket 607 to keep the gasket 607 flat, thereby preventing the hardware part body 12 from being unable to be tightly stuck with the hardware part body 12, resulting in serious wear of the hole, and preventing the hardware part body 12 from shaking in the hole during grinding, resulting in serious scratches, thereby ensuring the grinding effect.

[0046] like Figures 1 to 9 As shown, the present invention also discloses a hardware parts grinding machine, including the above-mentioned grinding assembly, the grinding disc 2 is arranged on the box assembly 1, the bottom of the grinding disc 2 is provided with a power assembly 3, the box assembly 1 is evenly provided with adjustment assemblies 4 with the central axis of the grinding disc 2 as the center of the circle, the adjustment assembly 4 is provided with a blocking assembly 5, the pressing assembly 6 is arranged corresponding to the blocking assembly 5, the center of the grinding disc 2 is provided with a drain port 10, the drain port 10 is provided with a limit position assembly 7, one side of the box assembly 1 is provided with a liquid supply assembly 8, the other side of the box assembly 1 is provided with a central control module 9, the user can control the opening and closing of the electrical components on the grinding machine through the central control module 9, and the blocking assembly 5 is provided with a detection assembly 11.

[0047] By setting the limit component 7, the clamping component 6 is stabilized so that it can maintain stable rotation and grinding on the grinding disc 2. The limit component 7 can also adjust the inclination angle of the clamping component 6 to make it parallel to the surface of the grinding disc 2, thereby ensuring that the pressure of the clamping component 6 on the hardware part body 12 is uniform, thereby ensuring uniform grinding force; by setting the blocking component 5, the bending degree of the blocking arm can be adjusted to adapt to hardware parts of different sizes, thereby avoiding the impact of replacement of the blocking arm on the grinding efficiency.

[0048] In the prior art, common stop arms are fixed on the work platform, and the bending degree or length of the stop arms are not adjustable, and can only adapt to hardware parts bodies 12 within a certain size range. Therefore, when it is necessary to grind a hardware part body 12 with a larger diameter, it is necessary to replace the stop ring 608 with a larger diameter. At this time, it is necessary to replace a larger stop arm to block the stop ring 608. The steps for replacing the stop arm are relatively cumbersome, which affects the grinding efficiency.

[0049] In order to solve the above technical problems, Figure 4-Figure 5 As shown, in this embodiment, the detection component 11 is set to detect whether the curvature of the elastic blocking arm 502 is appropriate, and the curvature is adjusted by setting the elastic blocking arm 502 to ensure that the auxiliary roller 501 can contact the retaining ring 608. The blocking component 5 includes an elastic blocking arm 502, and the elastic blocking arm 502 is evenly fixed with positioning columns 508, and the auxiliary roller 501 is rotatably set on the positioning column 508. The detection component 11 is fixedly set on the positioning column 508; the tops of the positioning columns 508 located at both ends of the elastic blocking arm 502 are respectively fixed with fixed columns 503 and movable columns 507, and the top of the fixed column 503 is fixedly provided with a supporting cross plate 504, and the supporting cross plate 504 is provided with a strip hole 509, and the supporting cross plate 504 is provided with a telescopic cylinder 505, and the output end of the telescopic cylinder 505 is fixedly connected with a moving block 506, and the top of the moving column 507 is fixedly connected with the moving block 506 through the strip hole 509. By controlling the extension and retraction of the output end of the telescopic cylinder 505, the curvature of the elastic blocking arm 502 is changed, so that the curvature of the elastic blocking arm 502 matches the retaining ring 608, thereby ensuring that the auxiliary roller 501 is in contact with the retaining ring 608. The detection component 11 includes a ring 1101 fixedly arranged on the positioning column 508, a detection spring 1103 is fixedly arranged on one side of the ring 1101, a detection frame 1104 is fixedly arranged on the end of the detection spring 1103 away from the ring 1101, a traction column 1102 is arranged on the outer array of the detection spring 1103, the detection frame 1104 is slidably arranged on the traction column 1102, and a detection roller 1105 is rotatably arranged on the side of the detection frame 1104 away from the detection spring 1103. The detection roller 1105 is subjected to pressure, thereby driving the detection frame 1104 to compress the detection spring 1103, so that it is known that the auxiliary roller 501 is currently in contact with the retaining ring 608.

[0050] When in use, the clamping assembly 6 is placed on the grinding disc 2, and then the grinding disc 2 is driven to rotate slowly by the power assembly 3, thereby driving the clamping assembly 6 to move and contact with the auxiliary roller 501. When the outer side surface of the retaining ring 608 contacts the auxiliary roller 501, the retaining ring 608 contacts the detection roller 1105, driving the detection roller 1105 and the detection frame 1104 to move along the traction column 1102 toward the positioning column 508, thereby compressing the detection spring 1103, and the compression amount of the detection spring 1103 is used as the contact signal between the retaining ring 608 and the auxiliary roller 501.

[0051] When all the detection springs 1103 on any elastic blocking arm 502 are compressed, it means that all the auxiliary rollers 501 on the elastic blocking arm 502 are in contact with the outer side of the retaining ring 608, and the bending arc of the elastic blocking arm 502 matches the retaining ring 608.

[0052] When the detection springs 1103 on the positioning columns 508 at both ends of the elastic barrier arm 502 are compressed, and the detection spring 1103 in the middle is not compressed, it means that the diameter of the retaining ring 608 is larger and the bending arc of the elastic barrier arm 502 is deeper. At this time, the output end of the telescopic cylinder 505 is controlled to extend, driving the moving block 506 to move, thereby driving the moving column 507 to move, so that the positioning column 508 at the right end of the elastic barrier arm 502 and the detection component 11 on its outer surface move toward the direction of the adjustment component 4, thereby making the bending arc of the elastic barrier arm 502 shallower, until all the detection springs 1103 are compressed, the output end of the telescopic cylinder 505 stops extending, and at this time, the adjusted bending arc of the elastic barrier arm 502 matches the retaining ring 608.

[0053] When the detection springs 1103 on the positioning columns 508 at both ends of the elastic barrier arm 502 do not generate any compression, the detection spring 1103 located in the middle generates compression, which means that the diameter of the retaining ring 608 is smaller at this time and the bending arc of the elastic barrier arm 502 is shallower. At this time, the output end of the telescopic cylinder 505 is controlled to retract, driving the moving block 506 to move, thereby driving the positioning column 508 located at the right end of the elastic barrier arm 502 and the detection component 11 on its outer surface to move away from the adjustment component 4 through the moving column 507, thereby deepening the bending arc of the elastic barrier arm 502 until all the detection springs 1103 generate compression, and then the output end of the telescopic cylinder 505 stops retracting. At this time, the adjusted bending arc of the elastic barrier arm 502 matches the retaining ring 608.

[0054] The detection component 11 is used to detect whether the diameter of the current retaining ring 608 is too large or too small relative to the bending degree of the elastic retaining arm 502. The bending degree of the elastic retaining arm 502 is adjusted by adjusting the left and right movement of the auxiliary roller 501 at the right end to ensure that the elastic retaining arm 502 can use retaining rings 608 of different sizes, ensure that hardware parts bodies 12 of different sizes can be ground, and avoid frequent replacement of retaining arms of different sizes that affect the grinding efficiency.

[0055] When the grinding disc 2 is in a grinding state for a long time, since the inner diameter of the grinding disc 2 is small and the outer diameter is large, the inner friction circles are more and the outer friction circles are less, the inner disc surface is severely worn and lower than the outer disc surface, resulting in the disc surface being low in the center and high around. At the same time, the clamping component 6 remains in a vertical state under the interception of the blocking component 5, which will cause the grinding force of the inner side of the grinding disc 2 on the hardware part body 12 to be smaller than the grinding force of the outer side, resulting in uneven grinding force of the hardware part body 12, affecting the grinding quality.

[0056] In order to solve the above technical problems, Figure 6As shown, in this embodiment, the inclination angle of the clamping assembly 6 is adjusted by setting a limit assembly 7, so that the clamping assembly 6 is adjusted according to the inclination angle of the grinding disc 2. The limit assembly 7 includes a rotating arm 704, one end of the rotating arm 704 is fixedly provided with a support cylinder 705, and the end of the support cylinder 705 away from the rotating arm 704 is slidably provided with a telescopic arm 706, a telescopic spring 707 is provided between the telescopic arm 706 and the rotating arm 704, and the end of the telescopic arm 706 away from the support cylinder 705 is fixedly provided with an interpenetrating column 708, and the interpenetrating column 708 is inserted into the sleeve cylinder 610 to limit the clamping assembly 6 to prevent the clamping assembly 6 from flying out of the grinding surface of the grinding disc 2 in the case of high-speed rotation grinding, resulting in grinding interruption and affecting the grinding efficiency. When the grinding disc 2 rotates, it will drive the clamping assembly 6 to rotate, and the sleeve cylinder 610 will rotate. The insertion column 708 rotates as the central axis; the end of the rotating arm 704 away from the supporting tube 705 is hinged with a connecting frame 703, and a rotating motor 709 is provided at the hinge point between the rotating arm 704 and the connecting frame 703. The angle of the telescopic arm 706 is adjusted by rotating the rotating motor 709 upward, thereby adjusting the inclination angle of the insertion column 708, and then adjusting the overall inclination angle of the clamping assembly 6. A rotating shaft 702 is fixedly provided at the center of the connecting frame 703, and the bottom of the rotating shaft 702 is rotatably connected to the column 701. A locking assembly is provided on the rotating shaft 702. When the insertion column 708 has not yet been inserted into the sleeve tube 610, the rotating shaft 702 is in a free rotation state. When the insertion column 708 is inserted into the sleeve tube 610, the locking assembly is activated to temporarily lock the rotating shaft 702 and the column 701 into a fixed state to ensure the stability of the clamping assembly 6. A fixing plate 710 is fixedly provided at the bottom of the column 701; one end of the fixing plate 710 is fixedly connected to a load-bearing cylinder 711, and a load-bearing frame 712 is fixedly provided on the outer surface of the load-bearing cylinder 711. The load-bearing frame 712 is fixedly provided inside the box assembly 1, and an annular groove is provided on the bottom surface of the grinding disc 2, and the load-bearing cylinder 711 is inserted into the annular groove. Driven by the power assembly 3, the grinding disc 2 rotates along the load-bearing cylinder 711.

[0057] During use, when the clamping assembly 6 is placed on the grinding disc 2 and the elastic retaining arm 502 is adjusted according to the retaining ring 608, the rotating shaft 702 is rotated so that the insertion column 708 can roughly correspond to the sleeve tube 610, and then the rotating motor 709 is controlled to rotate to drive the insertion column 708 to rotate to a horizontal state, so that the insertion column 708 can be inserted into the sleeve tube 610. At this time, the locking assembly is started to temporarily lock the rotating shaft 702 and the column 701 into a fixed state to ensure the stability of the clamping assembly 6.

[0058] The inclination degree from the center to the edge of the grinding disc 2 is measured by an angle measuring instrument, so as to obtain the inclination angle of the grinding disc 2. At this time, the rotating motor 709 is controlled to drive the rotating arm 704 and the telescopic arm 706 to rotate upward at an angle consistent with the inclination angle, so that the inserted column 708 changes from a vertical state to an inclined state, thereby driving the clamping assembly 6 as a whole to tilt from a vertical state toward the direction of the drain port 10 through the sleeve 610, so that the clamping assembly 6 can be adjusted with the inclination of the grinding surface of the grinding disc 2, thereby ensuring the uniformity of the pressure of the clamping assembly 6 on the hardware part body 12 and ensuring the grinding effect.

[0059] By setting the limiting assembly 7 to limit the clamping assembly 6, the clamping assembly 6 can maintain stable rotation and grinding on the grinding disc 2, preventing the clamping assembly 6 from flying out of the grinding surface of the grinding disc 2 under high-speed rotation and grinding; the inclination angle of the clamping assembly 6 can also be adjusted according to the inclination degree of the grinding surface of the grinding disc 2 so that the whole is parallel to the surface of the grinding disc 2, thereby ensuring the uniformity of the pressure applied by the clamping assembly 6 to the hardware part body 12.

[0060] When the pressing component 6 is adjusted to the inclined state, the blocking component 5 also needs to be adjusted accordingly, and the inclination angle of the blocking component 5 is adjusted by the adjusting component 4, such as Figure 7 As shown, the adjustment component 4 includes a positioning motor 401, a lifting plate 402 is fixedly provided at the bottom of the positioning motor 401, the output end of the positioning motor 401 passes through the lifting plate 402 and is fixedly connected to a right-angle plate 406, an adjustment motor 407 is provided at the top of the right-angle plate 406, and the output end of the adjustment motor 407 is fixedly connected to the supporting horizontal plate 504; a fixed vertical plate 403 is provided on one side of the lifting plate 402, a lifting cylinder 404 is provided on the side of the fixed vertical plate 403 away from the lifting plate 402, the output end of the lifting cylinder 404 is fixedly connected to a lifting frame 405, a through hole is opened on the fixed vertical plate 403, and one end of the lifting frame 405 passes through the through hole and is fixedly connected to the lifting plate 402.

[0061] When in use, according to the tilt angle, the control adjustment motor 407 rotates counterclockwise to an angle consistent with the tilt angle, thereby driving the left end of the supporting cross plate 504 to rotate downward, and the elastic blocking arm 502 rotates accordingly to ensure that the elastic blocking arm 502 and the clamping assembly 6 maintain synchronous tilt.

[0062] like Figure 8-Figure 9As shown, the power assembly 3 includes a driven wheel 304 fixedly arranged at the bottom of the grinding disc 2, a circular hole 305 is arranged at the center of the driven wheel 304, the diameter of the circular hole 305 is larger than the outer diameter of the bearing cylinder 711, and the circular hole 305 does not contact the bearing cylinder 711, a conveyor belt 303 is wound around the circumference of the driven wheel 304, and a driving motor 301 is arranged on the box assembly 1, the driving motor 301 is fixed on the top plate 102, and the output end passes through the top plate 102 and extends into the grinding machine box 101 to be connected with the driving wheel 302, the output end of the driving motor 301 is fixedly provided with the driving wheel 302, and the other end of the conveyor belt 303 is wound around the driving wheel 302; when the grinding disc 2 needs to be rotated, the driving motor 301 is started to drive the driving wheel 302 to rotate, and the driven wheel 304 is driven to rotate through the conveyor belt 303, thereby driving the grinding disc 2 to rotate.

[0063] A liquid supply component 8 is provided to provide grinding liquid for the grinding disc 2. The liquid supply component 8 includes a liquid storage barrel 801, in which grinding liquid is stored. The bottom of the liquid storage barrel 801 is fixedly arranged on the box assembly 1 through a connecting plate 802. A water pipe 805 and an extension plate 803 are fixedly arranged on the side of the liquid storage barrel 801 close to the grinding disc 2. A water pump 804 is arranged on the extension plate 803. The water pipe 805 is fixedly connected to the suction end of the water pump 804. The output end of the water pump 804 is fixedly connected to a water outlet pipe 806. The grinding liquid in the liquid storage barrel 801 is pumped out from the water pipe 805 by controlling the water pump 804, and then the grinding liquid is output to the grinding disc 2 through the water outlet pipe 806. The box assembly 1 includes a grinding machine box 101, a circular notch 104 is arranged at the center of the top plate 102 of the grinding machine box 101, a baffle 103 is arranged at the edge of the circular notch 104, the baffle 103 is used to prevent the grinding liquid from being thrown onto the top plate 102, the grinding disc 2 is arranged in the circular notch 104, and the diameter of the grinding disc 2 is smaller than the circular notch 104.

[0064] The working principle of the present invention is as follows: first, fix the hardware part body 12, place the retaining ring 608 on the grinding disc 2, and then insert the hardware part body 12 into the holes on the gasket 607 in sequence, and then put the hardware part body 12 and the gasket 607 into the retaining ring 608 first, and then align the clip 602 on the counterweight block 601 with the slot, and slide along the slot so that the counterweight block 601 is pressed on the hardware part body 12.

[0065] Secondly, adjust the curvature of the elastic retaining arm 502, start the driving motor 301, drive the active wheel 302 to rotate, drive the driven wheel 304 to rotate through the conveyor belt 303, thereby driving the grinding disc 2 to rotate at a low speed, and drive the clamping assembly 6 to move and contact the auxiliary roller 501. When the outer side surface of the retaining ring 608 contacts the auxiliary roller 501, the retaining ring 608 contacts the detection roller 1105, driving the detection roller 1105 and the detection frame 1104 to move along the traction column 1102 toward the positioning column 508, thereby compressing the detection spring 1103, and the compression of the detection spring 1103 is used as the contact signal between the retaining ring 608 and the auxiliary roller 501. When the detection springs 1103 on the positioning columns 508 at both ends of the elastic barrier arm 502 are compressed, and the detection spring 1103 in the middle is not compressed, it means that the diameter of the retaining ring 608 is larger and the bending arc of the elastic barrier arm 502 is deeper. At this time, the output end of the telescopic cylinder 505 is controlled to extend, driving the moving block 506 to move, thereby driving the moving column 507 to move, so that the positioning column 508 at the right end of the elastic barrier arm 502 and the detection component 11 on its outer surface move toward the direction of the adjustment component 4, thereby making the bending arc of the elastic barrier arm 502 shallower, until all the detection springs 1103 are compressed, the output end of the telescopic cylinder 505 stops extending, and at this time, the adjusted bending arc of the elastic barrier arm 502 matches the retaining ring 608. When the detection springs 1103 on the positioning columns 508 at both ends of the elastic barrier arm 502 do not generate any compression, the detection spring 1103 located in the middle generates compression, which means that the diameter of the retaining ring 608 is smaller at this time and the bending arc of the elastic barrier arm 502 is shallower. At this time, the output end of the telescopic cylinder 505 is controlled to retract, driving the moving block 506 to move, thereby driving the positioning column 508 located at the right end of the elastic barrier arm 502 and the detection component 11 on its outer surface to move away from the adjustment component 4 through the moving column 507, thereby deepening the bending arc of the elastic barrier arm 502 until all the detection springs 1103 generate compression, and then the output end of the telescopic cylinder 505 stops retracting. At this time, the adjusted bending arc of the elastic barrier arm 502 matches the retaining ring 608.

[0066] Then, adjust the inclination, turn the rotating shaft 702 to rotate, so that the insertion column 708 can roughly correspond to the sleeve 610, and then control the rotation motor 709 to rotate, drive the insertion column 708 to rotate to a horizontal state, so that the insertion column 708 can be inserted into the sleeve 610, and then start the locking assembly to temporarily lock the rotating shaft 702 and the column 701 into a fixed state. The inclination degree from the center to the edge of the grinding disc 2 is measured by an angle measuring instrument to obtain the inclination angle of the grinding disc 2. At this time, control the rotating motor 709 to drive the rotating arm 704 and the telescopic arm 706 to rotate upward at an angle consistent with the inclination angle, so that the insertion column 708 changes from a vertical state to an inclined state, thereby driving the clamping assembly 6 to tilt from a vertical state to the direction of the liquid discharge port 10 through the sleeve 610, so that the clamping assembly 6 can be adjusted with the inclination of the grinding surface of the grinding disc 2. At the same time, according to the tilt angle, the control adjustment motor 407 rotates counterclockwise to an angle consistent with the tilt angle, thereby driving the left end of the supporting cross plate 504 to rotate downward, and the elastic blocking arm 502 rotates accordingly to ensure that the elastic blocking arm 502 and the clamping assembly 6 maintain synchronous tilt.

[0067] Finally, the grinding is started, and the driving motor 301 is controlled to speed up and rotate at high speed, thereby driving the grinding disc 2 to rotate at high speed to grind the hardware part body 12. After grinding for a certain period of time, the grinding is ended.

[0068] Embodiment 2:

[0069] Based on the technical solution of the above-mentioned embodiment 1, the steps for the angle measuring instrument to measure the inclination angle of the grinding surface of the grinding disc 2 are relatively cumbersome, which affects the grinding efficiency, and it is necessary to measure in a faster and simpler way; when replacing the retaining ring 608 with a larger diameter, its center of circle will deviate from the edge of the grinding disc 2, causing part of the edge of the retaining ring 608 to exceed the edge of the grinding disc 2 and remain suspended, resulting in the hardware part body 12 being unable to be ground when it rotates through the suspended position, resulting in uneven grinding and reduced grinding efficiency; and the following technical solutions are proposed to solve the above-mentioned technical problems.

[0070] The steps of measuring the inclination angle of the grinding surface of the grinding disc 2 by an angle measuring instrument are rather complicated and cannot automatically identify the inclination angle, which is not conducive to improving the grinding efficiency; therefore, the auxiliary spring 606 is used to identify the inclined surface and determine the inclination angle.

[0071] After the counterweight 601 is pressed on the hardware body 12, the spherical block 605 presses the gasket 607 with the help of the elastic force of the auxiliary spring 606, so that the gasket 607 is pressed flat. At this time, the compression amount of the auxiliary spring 606 remains consistent. Subsequently, the clamping assembly 6 is driven by the grinding disc 2 to rotate until the outer side of the retaining ring 608 contacts the auxiliary roller 501, and the curved arc of the elastic retaining arm 502 is adjusted to match the retaining ring 608. At this time, no matter whether the grinding surface of the grinding disc 2 is horizontal or inclined, after the retaining ring 608 is intercepted by the elastic retaining arm 502, its top and bottom surfaces are in a horizontal state. Since the diameter of the gasket 607 is slightly smaller than the inner diameter of the retaining ring 608, when the grinding disc 2 is an inclined surface, the compression amount of the auxiliary spring 606 will change.

[0072] After the auxiliary spring 606 adjusts the bending arc in the elastic blocking arm 502, the compression amount of the auxiliary spring 606 remains consistent, and it can be determined that the grinding surface of the current grinding disc 2 is in a horizontal state, and the gasket 607 is in a horizontal state.

[0073] After the auxiliary spring 606 has adjusted the bending arc in the elastic retaining arm 502, the compression of the auxiliary spring 606 is in a uniformly changing state. It can be judged that the grinding surface of the current grinding disc 2 is tilted. After the gasket 607 and the hardware part body 12 are placed on the grinding surface, they will follow the grinding surface to tilt, but at this time the retaining ring 608 is in a horizontal state, resulting in the compression of the auxiliary spring 606 from the outside to the inside of the grinding disc 2. It shows a trend of gradually decreasing. At this time, the compression of the auxiliary spring 606 on the side of the counterweight block 601 close to the drain port 10 is the smallest, and the compression of the auxiliary spring 606 on the side of the counterweight block 601 away from the drain port 10 is the largest. The maximum and minimum lengths of the deformation of the auxiliary spring 606 are obtained according to the maximum and minimum compressions. The difference obtained by subtracting the minimum length from the maximum length is divided by the distance between the two auxiliary springs 606 to obtain the tangent value of the inclination angle, thereby obtaining the corresponding inclination angle. The limiting assembly 7 and the blocking assembly 5 are adjusted according to the inclination angle to ensure uniformity of the pressure applied by the pressing assembly 6 to the hardware part body 12, thereby ensuring uniform grinding force.

[0074] By real-time detection of the change in compression of the auxiliary spring 606, it is determined whether the grinding surface of the current grinding disc 2 is tilted, and then the tangent value of the tilt angle is obtained through the difference between the maximum and minimum deformation of the auxiliary spring 606 and the distance between the two auxiliary springs 606, thereby obtaining the angle of the tilt angle. The measurement method is automated to improve the grinding efficiency.

[0075] When grinding a larger-sized hardware part body 12, it is also necessary to replace the retaining ring 608 with a larger diameter. The larger diameter will cause the center of the retaining ring 608 to deviate from the edge of the grinding disc 2, causing part of the edge of the retaining ring 608 to exceed the edge of the grinding disc 2 and remain suspended, resulting in the hardware part body 12 being unable to be ground when it rotates through the suspended position, resulting in uneven grinding and reduced grinding efficiency.

[0076] When the center of the retaining ring 608 rotates at half of the straight line formed by the circumferential edge of the grinding disc 2 and the circumferential edge of the liquid discharge port 10, the retaining ring 608 is completely located on the grinding surface, and effective grinding is performed. At this time, the length formed by the rotating arm 704, the support cylinder 705, the telescopic spring 707, and the telescopic arm 706 is the optimal grinding length, and the stretching amount of the telescopic spring 707 is the optimal stretching amount. This data is entered into the central control module 9 as a reference control value.

[0077] After the limit assembly 7 and the blocking assembly 5 are adjusted according to the tilt angle, at this time, the stretching amount of the telescopic spring 707 is detected and compared with the optimal stretching amount. If the stretching amount of the telescopic spring 707 is detected to be greater than the optimal stretching amount, it means that the center of the current retaining ring 608 is offset to the edge of the grinding disc 2, and the pressing assembly 6 needs to be moved toward the direction of the liquid discharge port 10. At this time, the locking assembly is released, the rotating shaft 702 and the column 701 are in a free state, and at the same time, the positioning motor 401 is controlled to rotate slowly clockwise, driving the blocking assembly 5 to rotate clockwise, thereby driving the retaining ring 608 to move closer to the liquid discharge port 10, until the stretching amount of the telescopic spring 707 is equal to the optimal stretching amount, which means that at this time, the center of the retaining ring 608 is already located at half of the straight line formed by the circumferential edge of the grinding disc 2 and the circumferential edge of the liquid discharge port 10, the positioning motor 401 is stopped to drive the blocking assembly 5 to rotate, and the locking assembly is restored to lock the rotating shaft 702 and the column 701, and the grinding position of the retaining ring 608 is adjusted.

[0078] Conversely, if it is detected that the stretching amount of the telescopic spring 707 is less than the optimal stretching amount, it means that the center of the current retaining ring 608 is offset in the direction of the liquid discharge port 10, and the clamping assembly 6 needs to be moved in the direction of the edge of the grinding disc 2. At this time, the locking assembly is released, the shaft 702 and the column 701 are restored to a free state, and at the same time, the positioning motor 401 is controlled to rotate slowly counterclockwise, driving the blocking assembly 5 to rotate counterclockwise, thereby driving the retaining ring 608 to move in the direction of the edge of the grinding disc 2, until the stretching amount of the telescopic spring 707 is equal to the optimal stretching amount, which means that at this time, the center of the retaining ring 608 is already located at half of the straight line formed by the circumferential edge of the grinding disc 2 and the circumferential edge of the liquid discharge port 10, the positioning motor 401 is stopped, and the locking assembly is restored to lock the shaft 702 and the column 701, and the grinding position of the retaining ring 608 is adjusted.

[0079] By real-time detection of the stretching amount of the telescopic spring 707, it is determined whether the current retaining ring 608 is offset, and the blocking assembly 5 is driven to rotate by the positioning motor 401, thereby driving the retaining ring 608 to move and adjust its position on the grinding disk 2, ensuring that the retaining ring 608 is completely located on the grinding disk 2 for effective grinding, thereby ensuring the grinding efficiency.

[0080] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
