Description

Technical Field

[0001] This utility model belongs to the field of shell processing technology, specifically relating to a fixing component for grinding and processing a flywheel cover. Background Technology

[0002] The flywheel housing typically refers to the bell-shaped outer casing that surrounds the flywheel. It is primarily used for protection, dustproofing, and safety, and also serves as a guide for clutch operating mechanisms (such as the release bearing). In some designs, it is also integrated with or connected to the front end of the gearbox housing.

[0003] Grinding is an unavoidable process during the production of the flywheel cover. On the one hand, grinding (or milling) can remove deformed parts, restore its absolute flatness, and ensure that the gearbox can be installed flat, avoiding misalignment of the gearbox shaft system due to installation stress. On the other hand, grinding can remove defects on the mating surface, providing a smooth and clean surface, allowing new gaskets or sealants to achieve a perfect seal, ensuring airtightness and preventing oil leaks.

[0004] In current technology, the flywheel cover is typically clamped and fixed using a clamping device, and then polished using a grinder. However, during the polishing process, the flywheel cover cannot adjust its angle while clamped, causing inconvenience to the polishing process. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a fixing component for grinding flywheel covers, so as to solve the technical problem that the flywheel cover cannot adjust its own angle when clamped, which causes inconvenience to grinding.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixing assembly for grinding a flywheel cover includes a bracket and a clamping mechanism mounted on the bracket. The clamping mechanism includes an extension arm, a clamping block on the inner side of the free end of the extension arm, a rotating assembly between the extension arm and the clamping block, a shaft hole at the end of the free end of the extension arm, a rotating shaft rotatably connected to the shaft hole, a fixing block on the back of the clamping block, an installation groove on the outer side of the fixing block, a limiting shaft in the installation groove, a collar sleeved around the limiting shaft, a transition block connecting the collar and the rotating shaft, limiting elements on both sides of the collar to restrict the rotation of the collar, a second gear sleeved on the outer end of the rotating shaft, a motor on the free end of the extension arm, a third gear sleeved on the free end of the motor output shaft, and the third gear meshing with the second gear.

[0008] Furthermore, the limiting component includes a limiting rod that passes through the lower surface of the fixing block in a vertical direction and extends into the mounting groove. The limiting rod and the fixing block are connected by a thread. The top of the limiting rod is provided with a "gyroscope-shaped" limiting cone. The curved surface of the limiting cone abuts against the collar, thereby limiting the rotation of the collar.

[0009] Furthermore, the support includes a horizontal plate, a vertical plate is fixedly connected to one side of the horizontal plate, an extension plate is provided on the outer plate surface of the vertical plate away from the horizontal plate, and the clamping mechanism includes a first gear rotatably connected to the upper surface of the horizontal plate. There are two first gears arranged at intervals, and a rack is provided between the first gears. The rack meshes with the first gears on both sides. A cylinder is provided on the lower surface of the extension plate facing the rack, and the output shaft of the cylinder is fixedly connected to the end of the rack.

[0010] Furthermore, a limiting post is fixedly connected to the upper surface of the horizontal plate, and the first gear is sleeved around the limiting post, forming a rotatable connection between the first gear and the limiting post;

[0011] Furthermore, an extension arm is provided on the outer side of the first gear, and the extension arm is fixedly connected to the gear teeth on the first gear;

[0012] Furthermore, the inner side of the clamping block is the contact surface, which is arc-shaped and matches the arc-shaped sidewall of the flywheel housing, thereby increasing the contact area between the clamping block and the flywheel housing and improving the stability of the clamping.

[0013] The beneficial effects of this utility model are as follows:

[0014] Compared with existing technologies, the rotating component allows for different angle adjustments to the flywheel cover in the clamped state, eliminating the need for extensive adjustments to the grinding device and thus effectively improving the grinding effect and flexibility during the grinding process.

Detailed Implementation

[0021] Example 1, specifically as follows: Figures 1-3 As shown.

[0022] A fixing assembly for grinding and processing a flywheel cover includes a bracket 1 and a clamping mechanism 2 disposed on the bracket 1.

[0023] like Figure 1 As shown, the bracket 1 includes a horizontal rectangular plate 101, a vertical plate 102 is fixedly connected to one side of the plate 101, and a horizontally extending extension plate 104 is provided on the outer plate surface of the vertical plate 102 away from the plate 101. The extension plate 104 is welded and fixed to the vertical plate 102.

[0024] The clamping mechanism 2 includes a first gear 202 that is rotatably connected to the upper surface of the horizontal plate 101. There are two first gears 202 arranged at intervals. Specifically, a limit post 201 is fixedly connected to the upper surface of the horizontal plate 101. The first gear 202 is sleeved around the limit post 201, and a rotatable connection is formed between the first gear 202 and the limit post 201.

[0025] A rack 203 is provided between the first gears 202, and the rack 203 meshes with the first gears 202 on both sides. A through hole 103 is provided at the bottom of the vertical plate 102. One end of the rack 203 facing the vertical plate 102 passes through the through hole 103 and extends to the bottom of the extension plate 104. A cylinder 204 is provided on the lower surface of the extension plate 104, directly opposite the rack 203. The cylinder 204 is bolted to the extension plate 104, and the output shaft of the cylinder 204 is fixedly connected to the end of the rack 203. The cylinder 204 pushes the rack 203 to move, thereby driving the first gears 202 on both sides of the rack 203 to rotate in opposite directions.

[0026] An extension arm 205 is provided on the outer side of the first gear 202. The extension arm 205 is welded and fixed to the gear teeth on the first gear 202. During the rotation of the two first gears 202, the two extension arms 205 move relative to or away from each other. A clamping block 206 is provided on the inner side of the free end of the extension arm 205. The inner surface of the clamping block 206 is a contact surface. The contact surface is arc-shaped and matches the arc-shaped side wall of the flywheel cover, thereby increasing the contact area between the clamping block 206 and the flywheel cover and improving the stability of clamping.

[0027] In use, first, place the flywheel cover between the clamping blocks 206, then start the cylinder 204. The output shaft of the cylinder 204 pushes the rack 203 toward the flywheel cover. During this process, the first gear 202 on both sides rotates in opposite directions, thereby causing the extension arms 205 on both sides to move relative to each other and clamp and fix the flywheel cover.

[0028] like Figure 2 , Figure 3 As shown, a rotating assembly 3 is provided between the extension arm 205 and the clamping block 206. The free end of the extension arm 205 has a shaft hole, which faces the center of the back of the clamping block 206. The rotating assembly 3 includes a rotating shaft 301 that is rotatably connected to the shaft hole, and both ends of the rotating shaft 301 are exposed outside the extension arm 205.

[0029] A cuboid fixing block 302 is fixedly connected to the center of the back of the clamping block 206. An installation groove 303 is formed on the outer surface of the fixing block 302, and the cross-section of the installation groove 303 is arc-shaped. A vertical limiting shaft 304 is provided at the center of the installation groove 303, and both ends of the limiting shaft 304 are welded and fixed to the groove wall of the installation groove 303. A collar 305 is sleeved around the limiting shaft 304, located within the installation groove 303 and not in contact with it. The collar 305 is connected to the rotating shaft 301 via a transition block 306, one end of which is welded and fixed to the arc-shaped side of the collar 305, and the other end of which is welded and fixed to the inner end face of the rotating shaft 301.

[0030] Both sides of the collar 305 are provided with limiting members 307. The limiting member 307 includes a limiting rod 308 that passes vertically through the lower surface of the fixing block 302 and extends into the mounting groove 303. The limiting rod 308 is threadedly connected to the fixing block 302. The top of the limiting rod 308 is provided with a nut to facilitate the application of force to the limiting rod 308. The top of the limiting rod 308 is provided with a "gyroscope-shaped" limiting cone 309, and the bottom surface of the limiting cone 309 is welded and fixed to the top surface of the limiting rod 308. It is worth emphasizing that the curved surface of the limiting cone 309 abuts against the collar 305, thereby restricting the rotation of the collar 305.

[0031] When in use, if it is necessary to rotate the clamping block 206 in the horizontal direction to adjust the clamping angle, firstly, rotate the limiting member 307 downwards to separate the limiting cone 309 from the collar 305. Then, rotate the clamping block 206 to the required angle. Finally, rotate the limiting member 307 upwards so that the limiting cone 309 and the collar 305 abut against each other again, thereby limiting the horizontal rotation of the clamping block 206.

[0032] The rotating assembly 3 also includes a second gear 310 sleeved on the outer end of the rotating shaft 301. The second gear 310 is located outside the extension arm 205 and is keyed to the rotating shaft 301. A motor 311 is provided on the bottom surface of the free end of the extension arm 205. The motor 311 is fixedly connected to the top and bottom surfaces of the extension arm 205 by screws. A third gear 312 is sleeved on the free end of the output shaft of the motor 311. The third gear 312 meshes with the second gear 310 and is also keyed to the output shaft of the motor 311.

[0033] When in use, start the motor 311, which drives the rotating shaft 301 to rotate, thereby causing the clamping block 206 to rotate in the vertical direction, thus adjusting the tilt angle of the flywheel cover in the clamping state.

[0034] By rotating component 3, the flywheel cover in the clamped state can be adjusted at different angles without much adjustment to the grinding device, thereby effectively improving the grinding effect and the flexibility during the grinding process.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
