DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention. The present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0038] In one embodiment of the present invention, see Figures 1 to 11 , an edge grinding device for processing a snow thrower protective cover, comprising a protective cover housing 1, a base 4, a grinding box 5, an eccentric weight block 15, a high-frequency oscillation generator 16, a positioning and mounting assembly 41, an abrasive separation assembly 42 and a clamping assembly 43;

[0039] The protective cover housing 1 is provided with two sets of symmetrically arranged mounting grooves 2 on both sides, and a plurality of assembly holes 3 are arranged in the mounting grooves 2;

[0040] The clamping assembly 43 is installed on the base 4, and the clamping assembly 43 clamps and fixes the protective cover shell 1 through the mutual cooperation between the mounting groove 2 and the assembly hole 3, and drives the protective cover shell 1 to move, lift and rotate;

[0041] A plurality of groups of springs 6 are arranged between the base 4 and the grinding box 5, one end of the spring 6 is fixedly connected to the base 4, and the other end of the spring 6 is fixedly connected to the grinding box 5, so that the grinding box 5 is elastically supported by the spring 6;

[0042] The bottom of the grinding box 5 is fixedly connected to multiple groups of mounting seats 8, on which a high-speed motor 9 is fixedly installed, and the axis of the output shaft of the high-speed motor 9 coincides with the axis of the grinding box 5. A turntable 10 is fixedly connected to the output shaft of the high-speed motor 9, and two groups of connecting grooves 11 are fixedly connected to the outer wall of the turntable 10, and the two groups of connecting grooves 11 are non-parallel. A plug rod 13 is slidably connected in the connecting groove 11, and one end of the plug rod 13 passes through the connecting groove 11 and extends to the outside of the connecting groove 11. The eccentric counterweight 15 is fixedly connected to one end of the plug rod 13 set on the outside of the connecting groove 11, and a center rod 7 is fixedly installed at the center of the grinding box 5;

[0043] The positioning and installation assembly 41 is installed between the insertion rod 13 and the connecting groove 11, and is used to install and fix the insertion rod 13 and the connecting groove 11, so as to adjust the relative distance between the eccentric counterweight block 15 and the turntable 10, and then adjust the offset between the rotation center and the center of mass of the turntable 10;

[0044] The high-frequency oscillation generator 16 is provided in plurality, and the plurality of high-frequency oscillation generators 16 are divided into two groups, the two groups of high-frequency oscillation generators 16 are respectively mounted on the outer wall of the shell of the grinding box 5, and the two groups of high-frequency oscillation generators 16 are mounted on two groups of planes with different heights, and the oscillation frequencies of the two groups of high-frequency oscillation generators 16 are different, the output shaft of the high-frequency oscillation generator 16 passes through the grinding box 5 and is fixedly mounted with an oscillation paddle 17 arranged in the grinding box 5, the high-frequency oscillation generator 16 drives the oscillation paddle 17 to perform high-frequency oscillation, and then oscillates and layers different types of abrasives in the grinding box 5;

[0045] The bottom of the grinding box 5 is provided with a filter port 18, and one side of the filter port 18 is provided in an oblique direction;

[0046] The abrasive separation assembly 42 is installed on one side of the filter port 18 in the vertical direction, and is used to filter out metal powder and small-particle abrasive in the abrasive;

[0047] The grinding box 5 is filled with a composite abrasive 44 formed by mixing a plurality of abrasives. The composite abrasive 44 may be composed of corundum, brown corundum, and white corundum mixed in proportion, and the grain size of the corundum is smaller than that of the brown corundum, and the grain size of the brown corundum is smaller than that of the white corundum.

[0048] The present invention first mixes corundum, brown corundum and white corundum in proportion and adds them into the grinding box 5, and then drives the turntable 10 to rotate through the high-speed motor 9, and the turntable 10 drives the eccentric counterweight 15 to rotate through the connecting groove 11 and the insertion rod 13. At this time, due to the mutual offset and misalignment between the rotation center and the center of mass of the turntable 10, mechanical oscillation is generated, and the exciting force generated by the mechanical oscillation is transmitted to the abrasive through the grinding box 5, thereby driving the abrasive to rotate and oscillate around the center rod 7 in the grinding box 5. At the same time, the present invention can also adjust the relative distance between the eccentric counterweight 15 and the turntable 10 through the sliding connection between the connecting groove 11 and the insertion rod 13, and install and fix the insertion rod 13 and the connecting groove 11 through the positioning and installation component 41, thereby adjusting the offset between the rotation center and the center of mass of the turntable 10, and thereby adjusting the magnitude of the exciting force generated by the mechanical oscillation of the equipment;

[0049] During the oscillation process, due to the different densities and particle sizes of corundum, brown corundum, and white corundum in the abrasive, the abrasive will be initially stratified in the grinding box 5, and then the high-frequency oscillator will drive the oscillation paddle 17 to perform high-frequency oscillation in the vertical direction in the grinding box 5, and the different oscillation frequencies of the high-frequency oscillators at different heights will further accelerate the stratification of the abrasive. At this time, since the smaller the particle size number, the larger the particle size, the corundum with the largest particle size is located at the top of the grinding box 5, the brown corundum with a smaller particle size is located in the middle of the grinding box 5, and the white corundum with the smallest particle size is located at the bottom of the grinding box 5;

[0050] Afterwards, the protective cover shell 1 can be clamped and fixed by the clamping assembly 43, and the protective cover shell 1 can be driven to move and lift, so that the edge to be processed of the protective cover shell 1 is rotated to the side close to the grinding box 5. After the adjustment is completed, the first telescopic gas rod 29 can be controlled to retract, so as to drive the protective cover shell 1 to descend and insert into the abrasive in the grinding box 5. At the same time, the depth of the protective cover shell 1 inserted into the grinding box 5 can be controlled by controlling the lifting and lowering of the first telescopic gas rod 29. When the edge of the protective cover shell 1 is inserted into the corundum, the roughness of the protective cover shell 1 is abraded by the high-speed vibrating corundum and its higher hardness and large particles. While performing preliminary rapid cutting and grinding, after preliminary grinding, as the protective cover shell 1 continues to be inserted, the edge of the protective cover shell 1 passes over the diamond sand and is inserted into the brown corundum, so that the edge of the protective cover shell 1 is repeatedly ground and cut by the strong grinding force of the brown corundum. Finally, when the edge of the protective cover shell 1 passes over the brown corundum and is inserted into, the edge of the protective cover shell 1 is ground and polished by the white corundum with the smallest particle size and the high hardness and good wear resistance of the white corundum. After polishing, the protective cover shell 1 can be quickly pulled out of the grinding box 5 by the clamping component 43, thereby completing the edge grinding of the protective cover shell 1;

[0051] During the processing, due to the irregularity of the edge of the protective cover shell 1, the protective cover shell 1 can be driven to rotate by the clamping assembly 43, so as to control the processing of the edges of the protective cover shell 1 at different angles;

[0052] At the same time, the metal debris from grinding is repeatedly ground by the abrasive at high speed, and finally forms metal powder, which is oscillated and settled to the bottom of the grinding box 5. At this time, the metal powder and waste materials in the abrasive can be filtered out by the abrasive separation component 42, thereby improving the use efficiency of the abrasive.

[0053] In one case of this embodiment, see Fig.11 The positioning and mounting assembly 41 includes a first mounting hole 12 and a second mounting hole 14; the first mounting hole 12 is arranged in the end of the connecting groove 11 away from the turntable 10, and the second mounting hole 14 is provided with multiple groups, and the multiple groups of second mounting holes 14 are equidistantly arranged in the insertion rod 13, and a bolt with strong shear resistance is installed between the first mounting hole 12 and the second mounting hole 14;

[0054] The positioning and mounting assembly 41 connects the first mounting hole 12 and the second mounting hole 14 by means of bolts, thereby achieving a fixed connection between the connecting groove 11 and the insertion rod 13 .

[0055] In one case of this embodiment, see Fig. 9 and Fig.10 The abrasive separation assembly 42 includes a discharge port arranged on one side of the filter port 18 in the vertical direction, a discharge hopper 19 is installed on one side of the discharge port, a filter screen 20 is installed in the discharge port, a sliding baffle 21 is slidably installed between the discharge hopper 19 and the filter screen 20, a positioning groove 22 is fixedly connected to the bottom of the grinding box 5, the positioning groove 22 and the sliding baffle 21 are parallel to each other, and a positioning bolt 23 is installed between the sliding baffle 21 and the positioning groove 22;

[0056] The abrasive separation assembly 42 filters the metal debris and abrasive with too small specifications in the abrasive at the bottom of the grinding box 5 through the filter screen 20, and the filtered waste enters the discharge hopper 19 and is discharged through the discharge hopper 19. At the same time, the filter plate is closed by the setting of the sliding baffle 21. At the same time, the relative position between the sliding baffle 21 and the positioning groove 22 is positioned and fixed by the mutual cooperation of the positioning bolt 23, the sliding baffle 21 and the positioning groove 22. At this time, the relative position between the sliding baffle 21 and the filter screen 20 can be adjusted by adjusting the relative position between the positioning groove 22 and the sliding baffle 21, thereby adjusting the effective filtering width of the filter screen 20, and then adjusting the filtering rate of the filter screen 20.

[0057] In one case of this embodiment, see Figure 3 to Figure 7The clamping assembly 43 includes a slide rail 24 fixedly connected to both sides of the base 4, a slide seat 25 is slidably connected to the slide rail 24, a positioning cylinder 26 is fixedly connected to the slide seat 25, a sliding rod 27 is slidably connected in the positioning cylinder 26, one end of the sliding rod 27 passes through the positioning cylinder 26 and extends to the outside of the positioning cylinder 26, the sliding rod 27 is arranged on the end outside the positioning cylinder 26 and is fixedly connected to a lifting frame 30, a first telescopic gas rod 29 is installed on the slide seat 25, a driving frame 28 is fixedly installed on the output end of the first telescopic gas rod 29, and the driving frame 28 is fixedly connected to the sliding rod 27, and three groups of circumferentially distributed mounting shafts 31 are rotatably connected in the lifting frame 30, and a limited position gear 32 is fixedly connected to the mounting shaft 31, and a limited position gear 32 is arranged between the limited position gears 32. A rotating gear ring 33 is installed, and the rotating gear ring 33 is meshed with the limit gear 32. A mounting frame 34 is fixedly connected inside the rotating gear ring 33, and a second telescopic gas rod 35 is fixedly connected to the mounting frame 34. A connecting seat 36 is fixedly installed on the output end of the second telescopic gas rod 35, and a plurality of groups of positioning clamping rods 37 are fixedly connected to the connecting seat 36. The plurality of groups of positioning clamping rods 37 are slidably connected to the plurality of assembly holes 3. A servo motor 38 is fixedly installed on one side of the lifting frame 30, and the output shaft of the servo motor 38 is fixedly connected to a group of mounting shafts 31. A connecting frame 39 is fixedly connected between the sliding seats 25. A third telescopic gas rod 40 is fixedly installed on the base 4, and the output end of the third telescopic gas rod 40 is fixedly connected to the connecting frame 39.

[0058] When the clamping assembly 43 is clamping the protective cover shell 1, the first telescopic gas rod 29 is controlled to retract, the second telescopic gas rod 35 is controlled to retract, and the third telescopic gas rod 40 is extended. At this time, the positioning clamping rod 37 is unfolded under the drive of the three groups of telescopic gas rods and moved to the side away from the grinding box 5 and close to the base 4. At this time, the protective cover shell 1 can be placed between the two groups of connecting seats 36, and then the two groups of second telescopic gas rods 35 are controlled to extend synchronously. The second telescopic gas rods 35 drive the connecting seat 36 to extend toward the protective cover shell 1, so that the positioning clamping rod 37 is inserted into the assembly hole 3, so as to achieve the clamping and fixing of the protective cover shell 1. The above clamping method does not require additional clamping points, and at the same time avoids the shell deformation caused by rigid clamping, thereby increasing the clamping stability and convenience of the present invention;

[0059] After the clamping is completed, the first telescopic gas rod 29 can be extended to drive the lifting frame 30 to move to the side away from the sliding seat 25. The lifting frame 30 drives the protective cover shell 1 to rise through the connecting seat 36. At the same time, the third telescopic gas rod 40 drives the connecting frame 39 to move. The connecting frame 39 drives the sliding seat 25 to slide on the slide rail 24, and then drives the protective cover shell 1 to move toward the grinding box 5, so that the protective cover shell 1 is moved above the grinding box 5, and then a group of installation shafts 31 are driven to rotate by the servo motor 38, and the installation shaft 31 drives the limit gear 32 to rotate. The limit gear 32 drives the rotating ring gear 33 to rotate by engaging with the rotating ring gear 33. The rotating ring gear 33 drives the protective cover shell 1 to rotate through the mutual cooperation between the positioning clamping rod 37 and the assembly hole 3, and then the angle of the protective cover shell 1 is adjusted, so that the edge to be processed of the protective cover shell 1 is rotated to the side close to the grinding box 5. After the adjustment is completed, the first telescopic gas rod 29 can be controlled to retract, thereby driving the protective cover shell 1 to descend and insert into the abrasive in the grinding box 5. At the same time, the depth of the protective cover shell 1 inserted into the grinding box 5 can be controlled by controlling the lifting and lowering of the first telescopic gas rod 29.

[0060] In one case of this embodiment, the first telescopic gas rod 29, the second telescopic gas rod 35, the third telescopic gas rod 40, the high-speed motor 9, the servo motor 38 and the high-frequency oscillation generator 16 can also be connected to a computer to achieve CNC machining of the protective cover shell 1.
