[0011] As a further solution of the present invention, the support assembly includes a mounting plate, the inner wall of the mounting plate is fixedly connected to two slides, the slides penetrate and slide outside the support tube, the side of the slide away from the mounting plate is hinged with a connecting rod through a pin shaft, the bottom ends of the two connecting rods are hinged to the outside of the adjustment assembly through the pin shaft, and the outer wall of the mounting plate is provided with two mounting grooves, and the mounting grooves are slidably connected with a sliding bar, the mounting grooves and the sliding bar are both T-shaped, the outer sides of the two sliding bars are fixed to the inner wall of the grinding sheet, and a locking screw is installed below the inner wall of the mounting plate, and the mounting plate is fixed to the grinding sheet through the locking screw.

[0012] A method for using a shock absorber housing surface grinding device, the method comprising the following steps: When grinding the cylindrical shock absorber housing, the grinding assembly is controlled to make the support cylinder and the grinding sheet rise, the shock absorber housing is placed on the working box, the motor is controlled to drive the driving gear to rotate, and the driving gear drives the turntable to rotate through the driven gear. Since the sliding column in the positioning assembly is slidably connected in the arc-shaped slideway, the turntable can push the slider to slide horizontally in the slide hole through the sliding column during the rotation process, so that the four clamping plates are close to each other and contact the shock absorber housing. The clamping plate can correct the deviation of the shock absorber housing in the process of pushing it to move, which is convenient for locking the shock absorber housing, and at the same time, the shock absorber housing can always be located directly below the center of the grinding assembly; After completing the positioning of the shock absorber housing, the grinding machine is controlled to drive the support cylinder to rotate, and the fixed box can slide in the annular track outside the support cylinder. The fixed box is supported and limited by the track to ensure the stability of the support cylinder rotation. The support cylinder drives the four support components to rotate through the adjustment component, and the support component drives the external grinding sheet to rotate. When adjusting the position of the grinding sheet, the multi-stage electric hydraulic rod is controlled to work, so that the multi-stage electric hydraulic rod is extended and drives the support cylinder to move downward through the fixed box, and the support cylinder drives the grinding sheet to move downward through the adjustment component and the support component; When the guide rod in the adjusting assembly is inserted into the slot in the middle of the working box, the bearing seat is close to the working box. Because the bearing seat will not rotate after being subjected to resistance, the sliding rod and the supporting tube inside the bearing seat rotate normally. As the supporting tube moves downward, the sliding groove inside the sliding rod can slide outside the limiting rod, and the limiting rod squeezes the spring. During the movement of the sliding rod, multiple connecting rods can be squeezed through the pin shaft. The connecting rod deflects and pushes the slide plate to move horizontally. The slide plate drives the grinding sheet to approach the inner surface of the shock absorber housing through the mounting plate. When the grinding sheet contacts the inner surface of the shock absorber housing, multiple mounting plates drive multiple grinding sheets to rotate, so as to achieve the purpose of grinding the inner surface of the shock absorber housing. As the four grinding sheets continue to unfold, it is convenient to adjust the degree of grinding of the inner surface of the shock absorber housing, as well as the grinding work of shock absorber housings of different specifications. After the grinding work of the shock absorber shell is completed, the multi-stage electric hydraulic rod is controlled to contract to drive the fixing box and the grinder to move upward, so that the supporting cylinder moves upward synchronously. In the process of the supporting cylinder driving the supporting assembly and the grinding sheet to move upward, the elastic force of the spring supports the limit rod so that the slide groove inside the slide rod can slide downward on the outer wall of the limit rod, and the slide rod pulls the slide plate through multiple connecting rods, so that the slide plate drives the grinding sheet away from the inner surface of the shock absorber shell through the mounting plate, and cooperates with the upward movement of the supporting cylinder to separate the grinding assembly from the shock absorber shell. Secondly, the motor is controlled to reverse and drive the turntable to rotate. During the rotation of the turntable, the sliding column can slide in the slideway, so that the sliding column drives the splint away from the shock absorber shell through the sliding block. Because the multiple splints move synchronously, the locking state of the shock absorber shell can be quickly released, and the shock absorber shell can be removed from the working box. When replacing the grinding sheet, loosen the locking screw on the inner side of the mounting plate to make the end of the locking screw detach from the grinding sheet, so that the grinding sheet is in a free movable state, pull the grinding sheet vertically to drive the slide bar to slide inside the mounting groove until the slide bar is completely detached from the mounting groove, then the grinding sheet can be removed, and when installing the grinding sheet, insert the slide bar inside it into the mounting groove, and tighten the locking screw to fix the grinding sheet.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention controls the operation of the grinding assembly, and the multi-stage electric hydraulic rod is extended and drives the supporting cylinder to move downward through the fixed box. After the guide rod in the adjusting assembly is inserted into the slot in the middle of the working box, the bearing seat is close to the working box. Because the bearing seat will not rotate after being subjected to resistance, the sliding rod and the supporting cylinder inside the bearing seat rotate normally. As the supporting cylinder moves downward, the sliding groove inside the sliding rod can slide outside the limiting rod, and the limiting rod squeezes the spring. During the movement of the sliding rod, multiple connecting rods can be squeezed through the pin shaft. The connecting rod deflects and pushes the sliding plate to move horizontally. The sliding plate drives the grinding sheet to approach the inner surface of the shock absorber housing through the mounting plate. When the grinding sheet contacts the inner surface of the shock absorber housing, the multiple mounting plates are cooperated to drive the multiple grinding sheets to rotate, so as to achieve the purpose of grinding the inner surface of the shock absorber housing. As the four grinding sheets continue to unfold, it is convenient to adjust the degree of grinding of the inner surface of the shock absorber housing. When grinding shock absorber housings of different specifications, there is no need to replace grinding wheels of different sizes. It is only necessary to adjust the positions of multiple grinding sheets synchronously, thereby reducing the workload and improving the grinding efficiency.

[0014] 2. The present invention places the shock absorber housing on the working box, and the motor drives the driving gear to rotate. The driving gear drives the turntable to rotate through the driven gear. Since the sliding column in the positioning assembly is slidably connected in the arc-shaped slideway, the turntable can push the slider to slide horizontally in the slide hole through the sliding column during the rotation process, so that the four clamping plates are close to each other and contact the shock absorber housing. The clamping plates can correct the deviation of the shock absorber housing in the process of pushing the shock absorber housing to move, which is convenient for locking the shock absorber housing. At the same time, the shock absorber housing can always be located directly below the center of the grinding assembly, thereby achieving the purpose of calibrating the center of the shock absorber housing and ensuring the subsequent grinding accuracy.

[0025] A method for using a shock absorber housing surface grinding device, the method comprising the following steps: When grinding the cylindrical shock absorber housing, the grinding assembly 8 is controlled to work so that the support cylinder 10 and the grinding sheet 13 rise, and the shock absorber housing is placed on the working box 3. The motor 405 is controlled to work so that it drives the active gear 404 to rotate, and the active gear 404 drives the turntable 401 to rotate through the driven gear 403. Because the slide column 603 in the positioning assembly 6 is slidably connected in the arc-shaped slideway 402, the turntable 401 can push the slider 602 to slide horizontally in the slide hole 5 through the slide column 603 during the rotation process, so that the four clamping plates 601 are close to each other and contact the shock absorber housing. The clamping plates 601 can correct the deviation of the shock absorber housing in the process of pushing it to move, so as to facilitate the locking of the shock absorber housing, and at the same time, the shock absorber housing can always be located directly below the center of the grinding assembly 8; After completing the positioning of the shock absorber housing, the grinder 804 is controlled to drive the support tube 10 to rotate, and the fixed box 802 can slide in the annular track 9 outside the support tube 10, and the fixed box 802 is supported and limited by the track 9 to ensure the stability of the rotation of the support tube 10. The support tube 10 drives the four support assemblies 12 to rotate through the adjustment assembly 11, and the support assembly 12 drives the external grinding sheet 13 to rotate. When adjusting the position of the grinding sheet 13, the multi-stage electric hydraulic rod 801 is controlled to work, so that the multi-stage electric hydraulic rod 801 is extended and drives the support tube 10 to move downward through the fixed box 802, and the support tube 10 drives the grinding sheet 13 to move downward through the adjustment assembly 11 and the support assembly 12; When the guide rod 113 in the adjustment assembly 11 is inserted into the slot 7 in the middle of the working box 3, the bearing seat 112 is close to the working box 3. Since the bearing seat 112 will not rotate after being subjected to resistance, the sliding rod 111 and the support cylinder 10 inside the bearing seat 112 rotate normally. As the support cylinder 10 moves downward, the sliding groove 114 inside the sliding rod 111 can slide outside the limiting rod 116, and the limiting rod 116 squeezes the spring 115. During the movement of the sliding rod 111, multiple connecting rods 123 can be squeezed through the pin shaft to connect The rod 123 deflects and pushes the slide plate 122 to move horizontally, and the slide plate 122 drives the grinding sheet 13 to approach the inner surface of the shock absorber housing through the mounting plate 121. When the grinding sheet 13 contacts the inner surface of the shock absorber housing, the mounting plates 121 drive the grinding sheets 13 to rotate, so as to achieve the purpose of grinding the inner surface of the shock absorber housing.

In the process of the support tube 10 driving the support assembly 12 and the grinding sheet 13 to move upward, the limit rod 116 is supported by the elastic force of the spring 115, so that the slide groove 114 inside the slide rod 111 can slide downward on the outer wall of the limit rod 116, and the slide rod 111 pulls the slide plate 122 through the multiple connecting rods 123, so that the slide plate 122 passes through the mounting plate 1 21 drives the grinding sheet 13 away from the inner surface of the shock absorber housing, and cooperates with the support tube 10 to move up, so that the grinding assembly 8 can be separated from the shock absorber housing.

During the rotation of the turntable 401, the slide column 603 can slide in the slideway 402, so that the slide column 603 drives the clamping plate 601 away from the shock absorber housing through the slider 602. Because multiple clamping plates 601 move synchronously, the locking state of the shock absorber housing can be quickly released, and the shock absorber housing can be removed from the working box 3; When replacing the grinding sheet 13, loosen the locking screw 124 on the inner side of the mounting plate 121 to make the end of the locking screw 124 detach from the grinding sheet 13, so that the grinding sheet 13 is in a free movable state, pull the grinding sheet 13 vertically to drive the slide bar 14 to slide inside the mounting groove 125 until the slide bar 14 is completely detached from the mounting groove 125, and then the grinding sheet 13 can be removed. When installing the grinding sheet 13, insert the slide bar 14 inside it into the mounting groove 125, and tighten the locking screw 124 to fix the grinding sheet 13.

8. A method for using a shock absorber housing surface grinding device, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: When grinding the cylindrical shock absorber housing, the grinding assembly (8) is controlled to work so that the support cylinder (10) and the grinding sheet (13) rise, and the shock absorber housing is placed on the working box (3). The motor (405) is controlled to work so that it drives the driving gear (404) to rotate. The driving gear (404) drives the rotating disk (401) to rotate through the driven gear (403). Since the sliding column (603) in the positioning assembly (6) is slidably connected in the arc-shaped slideway (402), the rotating disk (401) can push the slider (602) to slide horizontally in the sliding hole (5) through the sliding column (603) during the rotation process, so that the four clamping plates (601) are close to each other and contact the shock absorber housing. The clamping plates (601) can correct the deviation of the shock absorber housing during the process of pushing the shock absorber housing to move, so as to facilitate the locking of the shock absorber housing, and at the same time, the shock absorber housing can always be located directly below the center of the grinding assembly (8); After the positioning of the shock absorber housing is completed, the grinding machine (804) is controlled to drive the support tube (10) to rotate, and the fixed box (802) can slide in the annular track (9) outside the support tube (10). The track (9) supports and limits the fixed box (802) to ensure the stability of the rotation of the support tube (10). The support tube (10) drives the four support assemblies (12) to rotate through the adjustment assembly (11), and the support assembly (12) drives the external grinding sheet (13) to rotate. When adjusting the position of the grinding sheet (13), the multi-stage electric hydraulic rod (801) is controlled to work, so that the multi-stage electric hydraulic rod (801) is extended and drives the support tube (10) to move downward through the fixed box (802), and the support tube (10) drives the grinding sheet (13) to move downward through the adjustment assembly (11) and the support assembly (12); When the guide rod (113) in the adjustment assembly (11) is inserted into the slot (7) in the middle of the working box (3), the bearing seat (112) is closely attached to the working box (3). Since the bearing seat (112) is subjected to resistance and does not rotate, the slide rod (111) and the support cylinder (10) inside the bearing seat (112) rotate normally. As the support cylinder (10) moves downward, the slide groove (114) inside the slide rod (111) can slide outside the limit rod (116), and the limit rod (116) squeezes the spring (115). During the movement of the slide rod (111), multiple connections can be squeezed through the pin shaft. The connecting rod (123) is deflected and pushes the slide plate (122) to move horizontally, and the slide plate (122) drives the grinding sheet (13) to approach the inner surface of the shock absorber housing through the mounting plate (121). When the grinding sheet (13) contacts the inner surface of the shock absorber housing, the plurality of mounting plates (121) drive the plurality of grinding sheets (13) to rotate, thereby achieving the purpose of grinding the inner surface of the shock absorber housing. As the four grinding sheets (13) are continuously unfolded, the degree of grinding the inner surface of the shock absorber housing can be adjusted conveniently, and the grinding work of shock absorber housings of different specifications can be performed; After the grinding of the shock absorber housing is completed, the multi-stage electric hydraulic rod (801) is controlled to contract so that it drives the fixing box (802) and the grinder (804) to move upward, so that the support tube (10) moves upward synchronously. In the process of the support tube (10) driving the support assembly (12) and the grinding sheet (13) to move upward, the limit rod (116) is supported by the elastic force of the spring (115), so that the slide groove (114) inside the slide rod (111) can slide downward on the outer wall of the limit rod (116), and the slide rod (111) pulls the slide plate (122) through the plurality of connecting rods (123), so that the slide plate (122) passes through the installation The plate (121) drives the grinding sheet (13) away from the inner surface of the shock absorber housing, and cooperates with the support tube (10) to move upward, so that the grinding assembly (8) and the shock absorber housing can be separated. Then, the motor (405) is controlled to reverse and drive the turntable (401) to rotate. During the rotation of the turntable (401), the slide column (603) can slide in the slideway (402), so that the slide column (603) drives the clamping plate (601) away from the shock absorber housing through the slider (602). Since the multiple clamping plates (601) move synchronously, the locking state of the shock absorber housing can be quickly released, and the shock absorber housing can be removed from the working box (3); When replacing the grinding sheet (13), the locking screw (124) on the inner side of the mounting plate (121) is loosened to disengage the end of the locking screw (124) from the grinding sheet (13), so that the grinding sheet (13) is in a free movable state. The grinding sheet (13) is pulled vertically to drive the slide bar (14) to slide inside the mounting groove (125) until the slide bar (14) is completely disengaged from the mounting groove (125). The grinding sheet (13) can then be removed. When installing the grinding sheet (13), the slide bar (14) inside the grinding sheet is inserted into the mounting groove (125). The locking screw (124) can be tightened to fix the grinding sheet (13).
