Description

Technical Field

[0001] The present invention relates to the technical field of shock absorber housing processing, and particularly to a surface grinding device for a shock absorber housing and a using method thereof. Background Technique

[0002] The shock absorber housing is an important part of the shock absorber, usually processed from steel materials, and is used to accommodate other components of the shock absorber, such as shock absorber pistons, cylinder sleeves, piston rods, springs, and damping liquids. The shock absorber housing is widely used in various equipment and systems that require shock absorption, such as automobiles, motorcycles, bicycles, industrial machinery, etc.

[0003] The surface grinding of the shock absorber housing is an important step in the production process of the shock absorber, which can improve the surface quality and working efficiency of the shock absorber. The center of the shock absorber housing is a through hole for sleeving the engine crankshaft, and a cavity is formed between the inner surface of the housing and the cover plate. When grinding the inner surface of the shock absorber housing, it needs to be fixed. Currently, multiple clamping plates are usually used to lock it around the shock absorber housing, which undoubtedly increases the workload for the disassembly and assembly of a batch of shock absorber housings, and it is difficult to ensure that each shock absorber housing is located at the center of the grinding mechanism, affecting the grinding accuracy. During the grinding process, the grinding mechanism needs to be extended into the inner surface of the shock absorber housing for grinding. However, when grinding shock absorber housings of different specifications, different sizes of grinding wheels need to be replaced, increasing the usage cost. Without replacing the grinding wheel, the position of the grinding wheel or the shock absorber housing needs to be adjusted manually to meet the grinding requirements, which not only increases the workload but also greatly reduces the grinding efficiency. Summary of the Invention

The bottom ends of the two multi-stage electric hydraulic rods are fixedly connected with a fixed box. A grinding machine is installed inside the fixed box. The output shaft of the grinding machine is fixed to the top of the support cylinder. A number of heat dissipation holes are opened on the outer wall of the fixed box.

[0010] As a further scheme of the present invention, an orbit is opened above the outer wall of the support cylinder, and the orbit is annular. The bottom of the fixed box is slidably connected in the orbit.

[0011] As a further scheme of the present invention, the adjusting component includes a sliding rod. A bearing seat is installed at the bottom end of the sliding rod. A guide rod is installed at the bottom of the bearing seat. The guide rod is conical in design, and the bottom end of the guide rod is inserted into the slot. The sliding rod penetrates and slides at the bottom of the support cylinder. A sliding groove is opened at the top end of the sliding rod. A limiting rod is slidably connected in the sliding groove. The top end of the limiting rod is fixed to the top of the inner wall of the support cylinder.

[0013] A method for using a surface grinding device for a shock absorber housing, the method comprising the following steps:

[0014] When grinding the cylindrical shock absorber housing, control the grinding assembly to work so that the support cylinder and the grinding sheet rise, place the shock absorber housing on the working box, control the motor to work so that it drives the driving gear to rotate, the driving gear drives the turntable to rotate through the driven gear, because 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 approach each other and contact the shock absorber housing, and the clamping plates can correct the deviation of the shock absorber housing during the process of pushing the shock absorber housing to move, which is convenient for locking the shock absorber housing, and at the same time enables the shock absorber housing to always be directly below the center of the grinding assembly;

[0015] After completing the positioning work of the shock absorber housing, control the grinding machine to work so that it drives the support cylinder to rotate, and the fixed box can slide in the annular track outside the support cylinder, and the fixed box is supported and limited by the track to ensure the stability of the rotation of the support cylinder. The support cylinder drives the four support assemblies to rotate through the adjusting assembly, and the support assemblies drive the external grinding sheet to rotate. When adjusting the position of the grinding sheet, control the multi-stage electric hydraulic rod to work, so that the multi-stage electric hydraulic rod extends 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 adjusting assembly and the support assembly;

[0016] When the guide rod in the adjusting component is inserted into the slot in the middle of the working box, the bearing seat closely adheres to the working box. Since the bearing seat is subject to resistance, it will not rotate. The sliding rod and the support cylinder inside the bearing seat rotate normally. As the support cylinder moves downward, the chute inside the sliding rod can slide outside the limiting rod, and the limiting rod presses the spring. During the movement of the sliding rod, it can press a plurality of connecting rods through the pin shaft. The connecting rods deflect and push the sliding plate to move horizontally. The sliding plate drives the grinding piece to approach the inner surface of the shock absorber housing through the mounting plate. When the grinding piece contacts the inner surface of the shock absorber housing, it drives a plurality of grinding pieces to rotate in cooperation with a plurality of mounting plates, achieving the purpose of grinding the inner surface of the shock absorber housing. As the four grinding pieces continue to unfold, it is convenient to adjust the degree of grinding the inner surface of the shock absorber housing and the grinding work for shock absorber housings of different specifications;

[0017] After completing the grinding work on the shock absorber housing, control the multi-stage electric hydraulic rod to contract, which drives the fixed box and the grinding machine to move upward, causing the support cylinder to move upward synchronously. During the process of the support cylinder driving the support component and the grinding piece to move upward, the limiting rod is supported by the elastic force of the spring, enabling the chute inside the sliding rod to slide downward on the outer wall of the limiting rod. The sliding rod pulls the sliding plate through a plurality of connecting rods, causing the sliding plate to drive the grinding piece away from the inner surface of the shock absorber housing through the mounting plate. In cooperation with the upward movement of the support cylinder, the grinding component can be separated from the shock absorber housing. Secondly, control the motor to reverse and drive the turntable to rotate. During the rotation of the turntable, the sliding column can slide in the slideway, causing the sliding column to drive the clamping plate away from the shock absorber housing through the slider. Since a plurality of clamping plates 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;

[0018] When replacing the grinding piece, loosen the locking screw inside the mounting plate so that the end of the locking screw disengages from the grinding piece, making the grinding piece in a freely movable state. Vertically pull out the grinding piece to drive the slide bar to slide inside the mounting groove until the slide bar completely disengages from the mounting groove, and then the grinding piece can be removed. When installing the grinding piece, insert the slide bar inside it into the mounting groove and tighten the locking screw to fix the grinding piece.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, by controlling the operation of the grinding assembly, the multi-stage electro-hydraulic rod extends and drives the support cylinder to move downward through the fixed box. After the guide rod in the adjustment assembly is inserted into the slot in the middle of the working box, the bearing seat closely adheres to the working box. Since the bearing seat is subject to resistance, it will not rotate. The slide rod and the support cylinder inside the bearing seat rotate normally. As the support cylinder moves downward, the chute inside the slide rod can slide outside the limit rod, and the limit rod presses the spring. During the movement of the slide rod, it can squeeze a plurality of connecting rods through the pin shaft. The connecting rods deflect and push 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, it drives a plurality of grinding sheets to rotate in cooperation with a plurality of mounting plates, achieving 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 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. Only by synchronously adjusting the positions of the plurality of grinding sheets can the work burden be reduced and the grinding efficiency be improved.

[0021] 2. In the present invention, by placing the shock absorber housing on the working box, the motor operates to drive 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, during the rotation of the turntable, it can push the slider to slide horizontally in the sliding hole through the sliding column, making the four clamping plates approach each other and contact the shock absorber housing. During the process of the clamping plate pushing the shock absorber housing to move, it can correct the deviation of the shock absorber housing, facilitating the locking of the shock absorber housing. At the same time, the shock absorber housing can always be located directly below the center of the grinding assembly, achieving the purpose of calibrating the center of the shock absorber housing and ensuring the subsequent grinding accuracy.

On the protruding part in the middle of the working box 3, a slot 7 is opened. Above the working box 3, a grinding component 8 is provided. The grinding component 8 is installed at the top of the inner wall of the frame 1. The bottom of the grinding component 8 is connected with a support cylinder 10. Inside the support cylinder 10, an adjusting component 11 is installed. The bottom end of the adjusting component 11 is inserted into the slot 7. Four support components 12 are installed on the outer wall of the adjusting component 11. The support components 12 penetrate and slide in the support cylinder 10. A grinding piece 13 is installed on the outer wall of the support component 12;

[0037] During operation, the support cylinder 10 drives a plurality of adjusting components 11 to rotate. The adjusting component 11 drives the grinding piece 13 to rotate through the support component 12, achieving the purpose of grinding the inner surface of the shock absorber housing. As the four grinding pieces 13 are continuously unfolded, it is convenient to adjust the degree of grinding the inner surface of the shock absorber housing. When grinding shock absorber housings of different specifications, only need to synchronously adjust the positions of the multiple grinding pieces 13, improving the operation convenience and processing efficiency.

[0038] As a further solution of the present invention, the driving component 4 includes a turntable 401. Four sliding channels 402 are opened on the turntable 401. The positioning components 6 penetrate and slide in the sliding channels 402, and the sliding channels 402 are arc-shaped.

The bottom of the driving gear 404 is fixed with a motor 405. The motor 405 is installed inside the working box 3;

[0039] During operation, during the rotation of the turntable 401, the sliding column 603 can push the slider 602 to horizontally slide in the sliding hole 5, making the four clamping plates 601 approach each other and contact the shock absorber housing. During the process of the clamping plate 601 pushing the shock absorber housing to move, it can correct the deviation of the shock absorber housing, facilitating the locking of the shock absorber housing.

[0040] As a further solution of the present invention, the positioning component 6 includes a clamping plate 601. Anti-slip lines are provided on the inner wall of the clamping plate 601. The bottom of the clamping plate 601 is fixed with a slider 602. The slider 602 is slidably connected in the sliding hole 5. The cross-sectional shapes of the slider 602 and the sliding hole 5 are both T-shaped. The bottom of the slider 602 is fixedly connected with a sliding column 603. The sliding column 603 is slidably connected in the sliding channel 402;

[0041] During operation, the slider 602 is limited through the sliding hole 5, and the T-shaped slider 602 is embedded in the side wall inside the sliding hole 5, improving the stability of the slider 602 driving the clamping plate 601 to move horizontally and preventing the clamping plate 601 from slipping out of the working box 3.

[0042] As a further solution of the present invention, the grinding assembly 8 includes two multi-stage electro-hydraulic rods 801. The bottom ends of the two multi-stage electro-hydraulic rods 801 are fixedly connected with a fixed box 802. A grinding machine 804 is installed inside the fixed box 802. The output shaft of the grinding machine 804 is fixed to the top of the support cylinder 10. A plurality of heat dissipation holes 803 are opened on the outer wall of the fixed box 802, enabling the heat generated during the operation of the grinding machine 804 to dissipate from the inside of the fixed box 802 and ensuring the working stability of the grinding machine 804.

[0043] As a further solution of the present invention, an orbit 9 is opened above the outer wall of the support cylinder 10, and the orbit 9 is of a circular design. The bottom of the fixed box 802 is slidably connected inside the orbit 9.

[0044] During operation, by controlling the grinding machine 804 to operate to drive the support cylinder 10 to rotate, the fixed box 802 can slide in the circular orbit 9 outside the support cylinder 10. The fixed box 802 is supported and limited by the orbit 9, ensuring the stability of the rotation of the support cylinder 10.

[0045] As a further solution of the present invention, the adjusting assembly 11 includes a sliding rod 111. A bearing seat 112 is installed at the bottom end of the sliding rod 111. A guide rod 113 is installed at the bottom of the bearing seat 112. The guide rod 113 is of a conical design, and the bottom end of the guide rod 113 is inserted into the slot 7. The sliding rod 111 penetrates and slides at the bottom of the support cylinder 10. A sliding groove 114 is opened at the top end of the sliding rod 111. A limiting rod 116 is slidably connected inside the sliding groove 114. The top end of the limiting rod 116 is fixed to the top of the inner wall of the support cylinder 10. A spring 115 is fixedly connected between the bottom of the inner wall of the sliding groove 114 and the limiting rod 116.

[0046] During operation, during the process of the support cylinder 10 driving the support assembly 12 and the grinding disc 13 to move upward, the limiting rod 116 is supported by the elastic force of the spring 115, enabling the sliding groove 114 to slide downward along the outer wall of the limiting rod 116. The sliding rod 111 then pulls the sliding plate 122 through a plurality of connecting rods 123, causing the sliding plate 122 to drive the grinding disc 13 away from the inner surface of the shock absorber housing through the mounting plate 121, facilitating the separation of the grinding disc 13 from the shock absorber housing.

[0047] As a further solution of the present invention, the support assembly 12 includes a mounting plate 121. Two sliding plates 122 are fixedly connected to the inner wall of the mounting plate 121. The sliding plates 122 penetrate and slide outside the support cylinder 10. One side of the sliding plate 122 away from the mounting plate 121 is hinged with a connecting rod 123 through a pin shaft. The bottom ends of the two connecting rods 123 are hinged outside the adjusting assembly 11 through a pin shaft. Two mounting grooves 125 are formed in the outer wall of the mounting plate 121. A sliding strip 14 is slidably connected in the mounting groove 125. Both the mounting groove 125 and the sliding strip 14 are designed in a T shape. The outer sides of the two sliding strips 14 are fixed to the inner wall of the grinding disc 13. A locking screw 124 is installed below the inner wall of the mounting plate 121. The mounting plate 121 is fixed to the grinding disc 13 through the locking screw 124;

[0048] During operation, when replacing the grinding disc 13, loosen the locking screw 124 inside the mounting plate 121 to make the end of the locking screw 124 disengage from the grinding disc 13. Vertically pull the grinding disc 13 to drive the sliding strip 14 to slide inside the mounting groove 125 until the sliding strip 14 completely disengages from the mounting groove 125, which is convenient for removing the grinding disc 13 from the mounting plate 121; when installing the grinding disc 13, insert the T-shaped sliding strip 14 into the T-shaped mounting groove 125 to prevent the grinding disc 13 from disengaging from the mounting plate 121 in the horizontal direction. Tighten the locking screw 124 to lock the grinding disc 13.

[0049] A usage method of a surface grinding device for a shock absorber housing, the usage method includes the following steps:

[0050] When grinding a cylindrical shock absorber housing, control the grinding assembly 8 to work to raise the support cylinder 10 and the grinding disc 13. Place the shock absorber housing on the working box 3. Control the motor 405 to work to drive the driving gear 404 to rotate. The driving gear 404 drives the turntable 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, during the rotation of the turntable 401, it can push the slider 602 to slide horizontally in the slide hole 5 through the sliding column 603, so that the four clamping plates 601 approach each other and contact the shock absorber housing. During the process of the clamping plate 601 pushing the shock absorber housing to move, it can correct the deviation of the shock absorber housing, which is convenient for locking the shock absorber housing, and at the same time enable the shock absorber housing to always be directly below the center of the grinding assembly 8;

[0051] 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;

[0052] 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. As the four grinding sheets 13 continue to unfold, it is convenient to adjust the degree of grinding the inner surface of the shock absorber housing, and to grind shock absorber housings of different specifications.

[0053] 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 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. Secondly, 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. 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;

[0054] When replacing the grinding disc 13, loosen the locking screw 124 inside the mounting plate 121 so that the end of the locking screw 124 disengages from the grinding disc 13, making the grinding disc 13 in a freely movable state. Vertically pull the grinding disc 13 to drive the slide bar 14 to slide inside the mounting groove 125 until the slide bar 14 completely disengages from the mounting groove 125, and then the grinding disc 13 can be removed. When installing the grinding disc 13, insert the slide bar 14 inside it into the mounting groove 125 and tighten the locking screw 124 to fix the grinding disc 13.

4. A method for using a shock absorber housing surface grinding device, according to claim 3, 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).
