Description

TECHNICAL FIELD

[0001] The utility model belongs to the production technology direction of automobile parts, concretely relates to a prevent type clamping mechanism for automobile production. BACKGROUND

[0002] In the modern automobile manufacturing industry, magnetic automobile parts (such as motor magnetic steel, sensor magnet, magnetic gear, etc.) are widely used in key fields such as power system, electronic control system and auxiliary equipment due to their unique electromagnetic performance. These parts usually have high precision and are easily damaged, and need to go through cutting, grinding, assembly and other processes in the production process, so high reliability, stability and applicability of the clamping mechanism are required.

[0003] Traditional clamping mechanisms mostly use mechanical clamping, which fixes the parts by opening and closing the clamping jaw. However, for magnetic automobile parts, this clamping method has obvious defects. Because the shapes of magnetic automobile parts are different and the size precision is high, it is difficult for mechanical clamping jaw to achieve precise positioning, and it is easy to shift or even fall off during handling and processing, which reduces production efficiency and increases waste rate. This phenomenon has become a problem that personnel in the field are eager to solve. SUMMARY

[0004] The utility model aims at the prior art device prevent type clamping mechanism for automobile production to solve the problems in the above background.

[0005] In order to solve the above technical problems, the utility model provides the following technical scheme: a prevent type clamping mechanism for automobile production, comprising a bottom plate, the top of the bottom plate is fixedly connected with a support frame, the inner cavity of the support frame is slidably connected with a moving plate, the front surface of the moving plate is fixedly connected with a mounting plate, the mounting plate is provided with a clamping assembly;

[0006] The clamping assembly includes: a rotating shaft, a first motor, and two fixed plates. The rotating shaft is rotatably connected to the top of the mounting plate via bearings. A worm gear is fixedly sleeved on the outer wall of the rotating shaft. The first motor is connected to the top of the mounting plate via a bracket. A worm gear is fixedly connected to the output end of the first motor via a coupling. A gear is fixedly connected to the top of the rotating shaft. The two fixed plates are fixedly connected to the top of the mounting plate relative to each other. A guide slide rod is fixedly connected between the two fixed plates. A clamping plate is slidably connected to the outer wall of the guide slide rod. The bottom of the clamping plate is in contact with the top of the mounting plate. The back of the clamping plate... A rack is fixedly connected to the clamping plate. An installation groove is provided on the right side of the clamping plate, and an electromagnet is connected in the installation groove. By starting the first motor, the worm gear is driven to rotate, which in turn drives the worm wheel and the shaft fixed to it to rotate. The gear at the top of the shaft rotates accordingly, and the rack meshing with the gear drives the clamping plate to slide on the guide slide rod. This allows the two sets of clamping plates to move relative to each other, achieving precise positioning and clamping of automotive parts. At the same time, for magnetic automotive parts, in addition to mechanical clamping, the magnetic force generated by energizing the electromagnet further attracts the parts, preventing them from falling off during processing or transportation and enhancing the stability of the clamping.

[0007] This utility model further explains that there are two sets of the rotating shaft, worm gear, gear, clamping plate, rack, mounting groove, and electromagnet, which are arranged opposite to each other on the left and right sides of the worm, so as to clamp the automotive parts symmetrically from both sides.

[0008] This utility model further illustrates that the two worm gears mesh with the worm, and the two racks mesh with the two gears.

[0009] This utility model further illustrates that the support frame is provided with a height adjustment mechanism, which includes a lead screw. The lead screw is rotatably connected to the bottom inner wall of the support frame via a bearing. The movable plate is threadedly connected to the outer wall of the lead screw. By rotating the lead screw, the movable plate can be driven to move up and down within the support frame, thereby moving the mounting plate and adjusting the height of the mounting plate and clamping assembly. This allows the clamping assembly to adapt to the processing needs of automotive parts of different heights, improving its versatility.

[0010] The present invention further explains that the height adjustment mechanism includes a second motor, which is connected to the top of the support frame. The top end of the lead screw passes through the support frame and is fixedly connected to the output end of the second motor through a coupling. By starting the second motor, the lead screw can be driven to rotate, thereby realizing the automatic adjustment of the height of the moving plate and the clamping assembly.

[0011] The present invention further explains that a limiting sliding hole is provided on the front of the support frame, and the outer wall of the moving plate is slidably connected to the limiting sliding hole. The limiting sliding hole limits the moving plate, so that the rotational motion of the moving plate is transformed into vertical movement, thus preventing the moving plate from shaking or deviating during the movement.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] By starting the first motor to drive the worm gear to rotate, the worm gear drives the worm wheel and the shaft fixed to it to rotate, and the gear at the top of the shaft rotates accordingly. The rack meshing with the gear drives the clamping plate to slide on the guide slide, so that the two sets of clamping plates move relative to each other to achieve precise positioning and clamping of automotive parts. At the same time, for magnetic automotive parts, on the basis of mechanical clamping, the magnetic force generated by energizing the electromagnet further attracts the parts, preventing them from falling off during processing or transportation, and enhancing the stability of clamping.

[0014] By starting the second motor to drive the lead screw to rotate, the rotation of the lead screw can drive the moving plate to move up and down within the support frame, so that the moving plate drives the mounting plate to move, thereby adjusting the height of the mounting plate and the clamping assembly. This allows the clamping assembly to adapt to the processing needs of automotive parts of different heights, improving its versatility. Attached Figure Description

The rotating shaft 51 is rotatably connected to the top of the mounting plate 4 via bearings, and a worm gear 52 is fixedly sleeved on the outer wall of the rotating shaft 51. Motor 53 is connected to the top of mounting plate 4 via a bracket. A worm gear 54 is fixedly connected to the output end of the first motor 53 via a coupling. A gear 55 is fixedly connected to the top of the rotating shaft 51. Two fixing plates 56 are fixedly connected to the top of mounting plate 4. A guide slide rod 57 is fixedly connected between the two fixing plates 56. A clamping plate 58 is slidably connected to the outer wall of the guide slide rod 57. The bottom of the clamping plate 58 is in contact with the top of mounting plate 4. A rack 59 is fixedly connected to the back of the clamping plate 58. The right side of the clamping plate 58... An installation slot 510 is provided, and an electromagnet 511 is connected inside the installation slot 510. There are two sets of components: a rotating shaft 51, a worm gear 52, a gear 55, a clamping plate 58, a rack 59, an installation slot 510, and an electromagnet 511, arranged opposite each other on the left and right sides of the worm 54. This allows for symmetrical clamping of automotive parts from both sides. Two worm gears 52 mesh with the worm 54, and two racks 59 mesh with two gears 55. The worm 54 is driven to rotate by starting the first motor 53. 4. The drive worm gear 52 and the rotating shaft 51 fixed thereto rotate, and the gear 55 at the top of the rotating shaft 51 rotates accordingly. The rack 59 meshing with the gear 55 drives the clamping plate 58 to slide on the guide slide rod 57, so that the two sets of clamping plates 58 move relative to each other to achieve precise positioning and clamping of automotive parts. At the same time, for magnetic automotive parts, on the basis of mechanical clamping, the magnetic force generated by energizing the electromagnet 511 further attracts the parts, preventing them from falling off during processing or transportation, and enhancing the stability of clamping.

[0023] Working principle: The first motor 53 drives the worm gear 54 to rotate, which in turn drives the worm wheel 52 and the fixed shaft 51 to rotate. The gear 55 at the top of the shaft 51 rotates accordingly, and the rack 59 meshing with the gear 55 drives the clamping plate 58 to slide on the guide slide rod 57. This allows the two sets of clamping plates 58 to move relative to each other, achieving precise positioning and clamping of automotive parts. For magnetic automotive parts, in addition to mechanical clamping, the magnetic force generated by energizing the electromagnet 511 further attracts the parts, preventing them from falling off during processing or transportation.

[0024] The support frame 2 is equipped with a height adjustment mechanism 6, which includes a lead screw 61. The lead screw 61 is rotatably connected to the inner bottom wall of the support frame 2 via a bearing. A movable plate 3 is threadedly connected to the outer wall of the lead screw 61. By rotating the lead screw 61, the movable plate 3 can be driven to move up and down within the support frame 2, thereby moving the mounting plate 4 and adjusting the height of the mounting plate 4 and the clamping assembly 5. This allows the clamping assembly 5 to adapt to the processing needs of automotive parts of different heights, improving its versatility. The height adjustment mechanism 6 also includes a second motor 62. The second motor 62 is connected to the top of the support frame 2. The top end of the lead screw 61 passes through the support frame 2 and is fixedly connected to the output end of the second motor 62 through a coupling. By starting the second motor 62, the lead screw 61 can be driven to rotate, realizing the automatic adjustment of the height of the moving plate 3 and the clamping assembly 5. A limit sliding hole is opened on the front of the support frame 2. The outer wall of the moving plate 3 is slidably connected to the limit sliding hole. The limit sliding hole limits the moving plate 3, so that the rotational motion of the moving plate 3 is converted into vertical movement, preventing the moving plate 3 from shaking or deviating during the movement.

[0025] Working principle: By starting the second motor 62, the lead screw 61 is driven to rotate. The rotation of the lead screw 61 can drive the moving plate 3 to move up and down in the support frame 2, so that the moving plate 3 drives the mounting plate 4 to move, thereby adjusting the height of the mounting plate 4 and the clamping assembly 5, so that the clamping assembly 5 can adapt to the processing needs of automotive parts of different heights.
