Description

Technical Field

[0001] The utility model relates to the field of mechanical parts processing, and more specifically, it relates to a burr grinding device for a power recovery device. Background Art

[0002] A power recovery device is a device that can convert the energy generated by mechanical movement into electrical energy or other forms of energy and store it. In high-strength new energy vehicles, the power recovery device mainly recovers braking energy and excess engine power to reduce energy waste and improve energy efficiency. Power recovery devices are often formed by stamping. After the power recovery device is stamped, burrs will form on the edge of one side of the power recovery device, affecting the normal use of the power recovery device. Therefore, the power recovery device after stamping needs to be polished to remove the burrs on the edges.

[0003] Existing grinding devices usually use a driving part to drive the sanding belt to rotate, and use a pressure plate to press the sanding belt tightly against the surface of the power recovery device to be polished, so as to grind the burrs of the power recovery device. However, the position of the pressure plate is usually fixed, which makes it impossible to adjust the close contact between the sanding belt and the surface of the power recovery device by adjusting the up and down height of the pressure plate. If the close contact between the sanding belt and the surface of the power recovery device is not enough, the grinding effect is poor and the burrs cannot be completely polished away. If the close contact between the sanding belt and the surface of the power recovery device is too close, the power recovery device itself will be worn during the grinding process, affecting the quality of the power recovery device.

[0052] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0053] In order to better understand the present invention, Figure 1-Figure 19 The burr grinding device of the power recovery device of the utility model is described in detail.

[0054] Embodiment 1:

[0055] like Figure 2-Figure 7 As shown, the power recovery device burr grinding device comprises:

[0056] The grinding assembly 100 includes a mounting portion 110, a driving portion 120 connected to the mounting portion 110, a sanding belt 130 sleeved on the driving portion 120, and a pressure regulating portion 140 connected to the mounting portion 110, wherein the driving portion 120 is used to drive the sanding belt 130 to rotate for grinding, and the pressure regulating portion 140 is used to adjust the degree of close contact between the sanding belt 130 and the surface of the power recovery device, and the pressure regulating portion 140 includes a fixing plate 141 connected to the mounting portion 110, a positioning plate 142 plugged into the fixing plate 141, a connecting plate 143 connected to the positioning plate 142, a rotating plate 144 rotatably connected to the connecting plate 143, a pressing member 145 connected to the rotating plate 144, a limiting bolt 146 penetrating the connecting plate 143 and the rotating plate 144, and a first limiting nut 147 and a second limiting nut 148 both threadedly connected to the limiting bolt 146;

[0057] The adjusting plate 142 is connected to the fixing plate 141 by bolts and nuts. The pressing piece 145 is used to press the abrasive belt 130 against the surface of the power recovery device. The first limiting nut 147 is fixedly connected to the top surface of the connecting plate 143. The second limiting nut 148 abuts against the rotating plate 144, and the second limiting nut 148 is located below the rotating plate 144. The limiting bolt 146 cooperates with the first limiting nut 147 and the second limiting nut 148 to limit the rotation state of the rotating plate 144.

[0058] The position adjustment component 200 is used to accommodate the power recovery device and adjust the position state of the power recovery device;

[0059] The supporting assembly 300 is used to support the grinding assembly 100 and the positioning assembly 200 .

[0060] The first through hole 1411 is connected to the first through hole 1411 of the fixing plate 141, and the first through hole 1411 of the fixing plate 141 is connected to the first through hole 1411 of the fixing plate 141. The bolts for fastening the adjusting plate 142 and the fixing plate 141 are passed through the first through hole 1411 and the first through hole 1411. When the bolts and nuts for fastening the adjusting plate 142 and the fixing plate 141 are loosened, the adjusting plate 142 can slide up and down along the length direction of the first through hole 1421, thereby driving the connecting plate 143, the rotating plate 144 and the pressing piece 145 to move synchronously, so as to adjust the height of the pressing piece 145 to a certain extent. When the bolts and nuts for fastening the adjusting plate 142 and the fixing plate 141 are tightened, the position of the adjusting plate 142 is fixed and cannot slide up and down.

[0061] The connecting plate 143 is penetrated by a second through hole 1431 corresponding to the first limiting nut 147, and the rotating plate 144 is penetrated by a second straight slot 1441 corresponding to the second through hole 1431. The limiting bolt 146 is penetrated by the second through hole 1431 and the second straight slot 1441. By tightening the second limiting nut 148, the second limiting nut 148 will squeeze the rotating plate 144, driving the rotating plate 144 to rotate along the first direction, so that the clamping piece 145 presses the sanding belt 130 against the surface of the power recovery device. By adjusting the distance between the second limiting nut 148 and the first limiting nut 147, the degree of downward pressure of the clamping piece 145 on the sanding belt 130 can be adjusted, thereby adjusting the degree of close contact between the sanding belt 130 and the surface of the power recovery device.

[0062] In this embodiment, both sides of the connecting plate 143 have a first wing plate 1432 that is bent downward, and both sides of the rotating plate 144 have a second wing plate 1442 that is bent downward. The second wing plate 1442 is rotatably connected to the first wing plate 1432 through the screw of the bolt, thereby realizing the rotatable connection between the rotating plate 144 and the connecting plate 143. The second wing plate 1442 can be fastened to the first wing plate 1432 by the cooperation of the nut and the bolt to prevent the rotating plate 144 from rotating around the screw of the bolt. If the second wing plate 1442 is not fixed to the first wing plate 1432, the extrusion force between the second limiting bolt 146 and the rotating plate 144 may cause the rotating plate 144 to bend near the second straight slot 1441, resulting in a weakened close fit between the sanding belt 130 and the surface of the power recovery device, which in turn leads to insufficient burr grinding.

[0063] After the installation of the abrasive belt 130 is completed, first loosen the bolts and nuts that fasten the adjusting plate 142 and the fixing plate 141, slide the adjusting plate 142 up and down, thereby driving the connecting plate 143, the rotating plate 144 and the pressing piece 145 to move synchronously, so that the pressing piece 145 is at a suitable height, and then tighten the bolts and nuts that fasten the adjusting plate 142 and the fixing plate 141 to fix the adjusting plate 142 on the fixing plate 141, and then first loosen the bolts and nuts that fasten the first wing plate 1432 and the second wing plate 1442, and then tighten the second limit plate 1432 and the second limit plate 1442. Nut 148, make the second limiting nut 148 abut against the rotating plate 144, and adjust the distance between the second limiting nut 148 and the first limiting nut 147 by continuing to screw the second limiting nut 148, so as to adjust the degree of close contact between the sand belt 130 and the surface of the power recovery device to be appropriate, and finally, tighten the bolts and nuts that fasten the first wing plate 1432 and the second wing plate 1442, fix the second wing plate 1442 on the first wing plate 1432, and complete the adjustment of the degree of close contact between the sand belt 130 and the surface of the power recovery device.

[0064] By using the power recovery device burr grinding device described in the utility model, the height of the clamping piece 145 can be preliminarily adjusted by adjusting the height of the adjusting plate 142, and then the distance between the second limiting nut 148 and the first limiting nut 147 can be adjusted by screwing the second limiting nut 148, thereby adjusting the degree of close contact between the sanding belt 130 and the surface of the power recovery device, ensuring that the sanding belt 130 will not cause wear to the power recovery device itself while completely grinding away the burrs, thereby greatly improving the grinding effect of the power recovery device.

[0065] Embodiment 2:

[0066] As a further optimization of Example 1, Figure 3 and Figure 4 As shown, both sides of the adjustment plate have a third wing plate 1422 bent inward.

[0067] It should be noted that after the sanding belt 130 is tensioned, the sanding belt 130 will generate an upward force on the clamping piece 145, and the force will be transmitted to the adjustment plate through the clamping piece 145, the rotating plate 144 and the connecting plate 143. During long-term grinding work, the adjustment plate may bend and deform, resulting in a weakened fit between the sanding belt 130 and the surface of the power recovery device, which in turn leads to insufficient burr grinding. By strengthening the bending strength of the adjustment plate through the third wing plate 1422, the service life of the adjustment plate can be increased. Even during long-term grinding work, the sanding belt 130 can be kept in proper fit with the surface of the power recovery device, thereby ensuring a good grinding effect.

[0068] Embodiment 3:

[0069] As a further optimization of Example 2, Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the adjustment plate is penetrated by a third straight slot 1423, and the length direction of the third straight slot 1423 is consistent with the width direction of the sanding belt 130, the connecting plate 143 is penetrated by a third through hole 1433 corresponding to the third straight slot 1423, and the connecting plate 143 is connected to the adjustment plate 142 by bolts and nuts.

[0070] It should be noted that the bolts for fastening the connecting plate 143 and the adjusting plate 142 are passed through the third straight slot 1423 and the third through hole 1433. When the bolts and nuts for fastening the connecting plate 143 and the adjusting plate 142 are loosened, the connecting plate 143 can move along the length direction of the third straight slot 1423, thereby driving the rotating plate 144 and the clamping piece 145 to move synchronously, and adjusting the clamping position of the clamping piece 145 on the sanding belt 130, so that the clamped part of the sanding belt 130 matches the part of the power recovery device that needs to be polished, to ensure that the burrs on the edge of the power recovery device can be polished away.

[0071] Embodiment 4:

[0072] As a further optimization of Example 3, Figure 3 As shown, the pressing member 145 is configured as a pressure roller, and the pressure roller is rotatably connected to the rotating plate 144 via a first rotating shaft 1451 .

[0073] It should be noted that, during the process of grinding the power recovery device by the rotation of the sanding belt 130, the friction between the sanding belt 130 and the clamping piece 145 will cause certain wear on both. By setting the clamping piece 145 as a pressure roller rotatably connected to the rotating plate 144, the friction loss between the sanding belt 130 and the clamping piece 145 can be reduced, thereby increasing the service life of the sanding belt 130 and the clamping piece 145 and reducing maintenance costs.

[0074] Embodiment 5:

[0075] As a further optimization of Example 4, Figure 2 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the mounting portion 110 includes a support 111 fixedly mounted on the support assembly 300, a vertical plate 112 connected to the support 111, a first mounting plate 113 connected to the vertical plate 112, an adjustment unit 114 connected to the first mounting plate 113, a second mounting plate 115 slidably fitted with the first mounting plate 113, and a third mounting plate 116 connected to the second mounting plate 115;

[0076] The driving unit 120 includes a motor 125 fixedly mounted on the first mounting plate 113, an active roller 121 drivingly connected to the motor 125, a deflection adjusting roller 122 rotatably connected to the adjusting unit 114, a first driven roller 123 rotatably connected to the third mounting plate 116, and a second driven roller 124 rotatably connected to the third mounting plate 116. The sanding belt 130 is sleeved on the outer rings of the active roller 121, the deflection adjusting roller 122, the first driven roller 123 and the second driven roller 124. The adjusting unit 114 is used to adjust the position state of the deflection adjusting roller 122.

[0077] It should be noted that the first mounting plate 113 is fixedly mounted with a first limiting plate 1131 of a U-shaped structure, the first limiting plate 1131 and the first mounting plate 113 form a first sliding groove 1132 that is slidably matched with the second mounting plate 115, the first limiting plate 1131 is threadedly connected with a first locking bolt 1133, the first locking bolt 1133 extends out of the outer ring of the first limiting plate 1131 and is fixedly sleeved with a first rotating handle 1134, the first locking bolt 1133 can be driven to rotate by rotating the first rotating handle 1134, and when the first locking bolt 1133 is loosened, the second mounting plate 115 is 15 can slide in the first slide groove 1132 along its own length direction, thereby driving the third mounting plate 116, the first driven roller 123 and the second driven roller 124 to move synchronously, which is convenient for the installation of the abrasive belt 130, so that the active roller 121, the deflection adjustment roller 122, the first driven roller 123 and the second driven roller 124 can tighten the abrasive belt 130. When the first locking bolt 1133 is tightened, the first locking bolt 1133 presses the second mounting plate 115, thereby locking the position of the second mounting plate 115, preventing the second mounting plate 115 from moving and affecting the tension state of the abrasive belt 130.

[0078] The motor 125 drives the active roller 121 to rotate, thereby driving the abrasive belt 130 to rotate, and further driving the deviation adjustment roller 122 , the first driven roller 123 and the second driven roller 124 to rotate.

[0080] When the two sets of bolts and nuts fastening the third mounting plate 116 and the second mounting plate 115 are loosened, the third mounting plate 116 can rotate around one of the bolts, and the other bolt slides relatively with the arc notch 1163, thereby driving the first driven roller 123 and the second driven roller 124 to move. When the two sets of bolts and nuts fastening the third mounting plate 116 and the second mounting plate 115 are tightened, the positions of the third mounting plate 116, the first driven roller 123 and the second driven roller 124 are fixed. Since the sand belt 130 is sleeved on the outer rings of the active roller 121, the deviation adjustment roller 122, the first driven roller 123 and the second driven roller 124, the positions of the first driven roller 123 and the second driven roller 124 can be adjusted by adjusting the position state of the third mounting plate 116, and then the position state of the sand belt 130 is adjusted to prevent the sand belt 130 from contacting the parts of the pressure regulating part 140 except the pressing piece 145, thereby affecting the normal rotation of the sand belt 130.

[0081] The first mounting plate 113 is also fixedly mounted with a second limiting plate 1135 of a U-shaped structure, the second limiting plate 1135 and the first mounting plate 113 form a second sliding groove 1136 that is slidably matched with the vertical plate 112, the second limiting plate 1135 is threadedly connected with a second locking bolt 1137, the second locking bolt 1137 extends out of the outer ring of the second limiting plate 1135 and is fixedly sleeved with a second rotating handle 1138, the second locking bolt 1137 can be driven to rotate by rotating the second rotating handle 1138, and when the second locking bolt 1137 is loosened, the first mounting plate 113 can move up and down along the length direction of the vertical plate 112, thereby driving the punching The grinding assembly 100 (except the support 111 and the vertical plate 112) moves to adjust the height of the sanding belt 130 so that the sanding belt 130 is not lower than the height of the side of the power recovery device that needs to be polished, thereby preventing the sanding belt 130 from contacting the adjustment assembly 200, thereby affecting the normal rotation of the sanding belt 130, or causing wear to the power recovery device itself during the sanding process of the sanding belt 130. When the second locking bolt 1137 is tightened, the second locking bolt 1137 presses the vertical plate 112, thereby locking the position of the first mounting plate 113, thereby preventing the first mounting plate 113 from moving and affecting the sanding belt 130 from polishing the power recovery device.

[0083] As a further optimization of Example 5, Figure 8 , Fig. 9 , Fig.13 , Fig.14 , Fig.15 and Fig.16As shown, the adjustment unit 114 includes a support plate 11401 fixedly mounted on the first mounting plate 113, a rotating rod 11402 rotatably connected to the support plate 11401, a positioning plate 11403 connected to the rotating rod 11402, a third positioning shaft 11404 fixedly connected to the positioning plate 11403, a limit block 11405 fixedly mounted on the rotating rod 11402, a connecting rod 11406 rotatably connected to the rotating rod 11402, a handle 11407 fixedly mounted on the connecting rod 11406, and a gas spring 11408 rotatably connected to the connecting rod 11406, the gas spring 11408 is rotatably connected to the first mounting plate 113 via a fixed shaft 1139, and the deviation adjustment roller 122 is rotatably sleeved on the outer ring of the third positioning shaft 11404.

[0084] It should be noted that the fixed shaft 1139 is fixedly mounted on the first mounting plate 113 , one end of the gas spring 11408 is rotatably connected to the connecting rod 11406 , and the other end of the gas spring 11408 is rotatably connected to the fixed shaft 1139 .

[0085] When the abrasive belt 130 is initially sleeved on the outer rings of the active roller 121, the deflection adjustment roller 122, the first driven roller 123 and the second driven roller 124, the adjustment unit 114 is in the first state, the connecting rod 11406 is in a horizontal state, the length direction of the handle 11407 is perpendicular to the length direction of the connecting rod 11406, the angle between the connecting rod 11406 and the rotating rod 11402 is an obtuse angle, the gas spring 11408 is in a vertical state, and the abrasive belt 130 is not fully stretched. Tighten; turn the handle 11407 in the direction away from the rotating rod 11402, driving the connecting rod 11406, the gas spring 11408 and the rotating rod 11402 to rotate until the connecting rod 11406 abuts against the limit block 11405. During this process, the angle between the rotating rod 11402 and the horizontal direction increases, driving the positioning plate 11403, the third positioning shaft 11404 and the deviation adjustment roller 122 to move obliquely upward to tighten the sanding belt 130. At this time, the adjusting unit 11 In the second state, the length direction of the handle 11407 is tilted downward in the direction away from the rotating rod 11402, the angle between the connecting rod 11406 and the rotating rod 11402 is an acute angle, and the angle between the gas spring 11408 and the connecting rod 11406 is an obtuse angle. The gas spring 11408 is compressed. Under the action of the restoring force of the gas spring 11408, the connecting rod 11406 and the limit block 11405 are kept in contact. In the absence of sufficient external force, the rotating rod 114 02. The connecting rod 11406 and the gas spring 11408 no longer rotate, and the sanding belt 130 remains taut. The friction between the sanding belt 130 and the driving unit 120 is large enough so that the active roller 121 drives the sanding belt 130 to rotate, and then drives the deviation adjustment roller 122, the first driven roller 123 and the second driven roller 124 to rotate at the same time. The sanding belt 130 is not easy to slip during the process of grinding the power recovery device, thereby improving the grinding efficiency and grinding effect of the sanding belt 130.

[0086] Embodiment 7:

[0087] As a further optimization of Example 6, Fig.13 , Fig.14 , Fig.15 , Fig.16 and Fig.17 As shown, the adjustment unit 114 also includes a second rotating shaft 11409 rotatably connected to the rotating rod 11402, a gear 11410 fixedly sleeved on the outer ring of the second rotating shaft 11409, and a locking nut 11411 threadedly connected to the second rotating shaft 11409. The positioning plate 11403 is rotatably connected to the rotating rod 11402 via a third rotating shaft 11412, and a tooth groove 11413 meshing with the gear 11410 is provided on the side of the positioning plate 11403 close to the gear 11410.

[0088] It should be noted that the sanding belt 130 may deviate during the rotation, causing the sanding belt 130 to fall off the driving unit 120. The sanding belt 130 needs to be adjusted to ensure that the driving unit 120 drives the sanding belt 130 to rotate stably. When the locking nut 11411 is loosened, the second rotating shaft 11409 can rotate. Rotating the second rotating shaft 11409 drives the gear 11410 to rotate, thereby driving the positioning plate 11403 to rotate around the third rotating shaft 11412, and then adjusting the angle of the third positioning shaft 11404 and the center axis of the deviation adjustment roller 122. By adjusting the angle of the center axis of the deviation adjustment roller 122, the sanding belt 130 can be adjusted until the sanding belt 130 no longer deviates during the rotation. Tighten the locking nut 11411 to fix the second rotating shaft 11409 to ensure that the angle of the center axis of the deviation adjustment roller 122 no longer changes.

[0089] Embodiment 8:

[0090] As an optimization of Example 7, Figure 2 , Fig.18 and Fig.19 As shown, the positioning assembly 200 includes a driving unit 210 connected to the supporting assembly 300 and a supporting platform 220 connected to the driving unit 210. The supporting platform 220 is provided with a limiting groove 221 which is engaged with the power recovery device. The limiting groove 221 is used to limit the power recovery device in the horizontal direction. The depth of the limiting groove 221 is less than the thickness of the power recovery device. The driving unit 210 is used to drive the supporting platform 220 to move, thereby driving the power recovery device to move to the bottom of the sanding belt 130 for burr grinding.

[0091] It should be noted that the limit groove 221 can limit the power recovery device in the horizontal direction to prevent the power recovery device from moving in the horizontal direction during the process of grinding the burrs of the power recovery device by the sanding belt 130, thereby affecting the grinding efficiency; the depth of the limit groove 221 is less than the thickness of the power recovery device. In other words, the surface of the power recovery device to be polished is higher than the top surface of the support platform 220, so that the sanding belt 130 can grind the burrs of the power recovery device.

[0092] Embodiment 9:

[0093] As a further optimization of Example 8, Figure 2 and Fig.18 As shown, the driving unit 210 includes two guide rails 211 fixedly connected to the supporting assembly 300, a slide 212 slidably connected to the two guide rails 211, a cylinder 213 drivingly connected to the slide 212, a reduction motor 214 fixedly installed in the slide 212, and a control button 215 installed on the supporting assembly 300. The length directions of the two guide rails 211 are consistent with the width direction of the sanding belt 130. The cylinder 213 is fixedly installed on the supporting assembly 300, the reduction motor 214 is drivingly connected to the supporting table 220, and the supporting table 220 is rotatably connected to the slide 212. The control button 215 is used to control the operating status of the cylinder 213 and the reduction motor 214.

[0094] It should be noted that the power recovery device includes a main body 410, a first dome 420 connected to the main body 410, and a second dome 430 connected to the main body 410. The outer diameter of the second dome 430 is larger than the outer diameter of the first dome 420. The surface of the power recovery device that needs to be polished is the surface of the main body 410 close to the second dome 430. Since the surface of the power recovery device that needs to be polished is in contact with the sanding belt 130, the second dome 430 will hinder the sanding belt 130 from polishing the power recovery device. If the power recovery device cannot rotate during the polishing process, it is necessary to remove the power recovery device several times and adjust the angle of the power recovery device to completely polish the power recovery device. By setting the reduction motor 214 to drive the support platform 220 to rotate, thereby driving the power recovery device to rotate, the sanding belt 130 can completely polish the power recovery device at one time, thereby improving the polishing efficiency.

[0095] The extension and retraction state of the cylinder 213 can be controlled by a three-position five-way solenoid valve, and the operating states of the three-position five-way solenoid valve and the reduction motor 214 can be controlled by a relay. The control button 215 can control the relay to transmit electrical signals to the three-position five-way solenoid valve and the reduction motor 214. The three-position five-way solenoid valve, the reduction motor 214 and the control button 215 are all electrically connected to the relay.

[0096] After placing the power recovery device into the limit groove 221 of the support platform 220, press the control button 215, the cylinder 213 drives the slide 212, the reduction motor 214, the support platform 220 and the power recovery device to move to the specified position, and at the same time, the reduction motor 214 drives the support platform 220 and the power recovery device to rotate, and the sanding belt 130 grinds the burrs of the power recovery device. After a certain period of time, the burrs of the power recovery device are polished, and the cylinder 213 drives the slide 212, the reduction motor 214, the support platform 220 and the power recovery device to move to the initial position. At the same time, the reduction motor 214 stops rotating, and the polished power recovery device is removed.

[0099] It should be noted that the support 111, the guide rail 211 and the cylinder 213 are all fixedly mounted on the support plate 310, the three-position five-way solenoid valve and the relay can be installed on the mounting platform 330, and an air gun can also be installed on the mounting platform 330. When the power recovery device is polished and taken out from the limit groove 221, the air gun can be used to blow away the iron filings in the limit groove 221 and the iron filings attached to the surface of the power recovery device, so as to facilitate the cleaning of the limit groove 211 and the power recovery device after polishing.
