When preparing, the thickness of the brake disc is an integer multiple of the thickness of the disc part. In this way, when the multiple disc parts in the U-shaped card move toward the brake disc, it is convenient for the disc parts on both sides to limit the brake disc, and the corresponding number of disc parts move into the U-shaped card. At the same time, through the misalignment between the disc parts, it can effectively adapt to various specifications of brake disc parts to be braked.

At the same time, when the external force is reduced, the collar member can be driven to reset by the resistance tension spring member to realize the lifting of the collar member, and the second gear member and the spur rack can be matched to rotate the carrier toward the lower end of the chuck member, so that the resisting rod and the lower end of the chuck member are in conflict, and the push rod can push the carrier plate to move. Through the cooperation of the carrier and the carrier plate, the brake disc can be carried, and after the clamping is completed, the carrier and the carrier plate can be reset, so as to facilitate the processing of the front and rear of the brake disc; 3. When the collar part is lifted or lowered, it can drive the oblique push rod part connected to it to operate, that is, when the collar part is lowered, it can pull the oblique push rod part to make the second ring move, and the second ring drives the oblique rod part to move in a direction parallel to the slide rod on the same side thereof, and can push the contact plate to move toward the axis position of the chuck part, and can clamp the brake disc; That is, when the collar and the chuck are in conflict, the carrier plate and the carrier frame move into the hole in the chuck to carry the brake disc to be processed; when the clamping adaptation mechanism realizes the initial clamping of the brake disc to be processed, the collar and the chuck can be controlled to separate, which can push the carrier frame and the carrier plate out of the inner hole of the chuck, and at the same time enable the conflicting clamping mechanism to clamp the brake disc to be processed, and at the same time effectively expose the side of the brake disc to be processed close to the carrier frame and the carrier plate, so as to expose both sides of the brake disc to be processed; 4.

An arc-shaped card plate linkage member 315 is slidably installed in the lifting groove 311. The arc-shaped card plate linkage member 315 is a plate body with a C-shaped cross-section. A lifting push rod member 313 passes through and is slidably installed therein. A lifting push rod member 313 is slidably installed in the arc-shaped card plate linkage member 315. A reset spring member 314 is jointly installed between the lifting push rod member 313 and the vertical plate member 31. The reset spring member 314 is tilted, and the lower end of the reset spring member 314 is located on the side of the lower end of the lifting groove 311 away from the L-shaped rod member 411.

[0033] The cam 312 is provided on the upper surface of the support frame 311, and the lifting and lowering rod 313 is slidably sleeved in the sliding plate 312. The lifting and lowering rod 313 is connected to the rotating bearing mechanism 4. A plurality of rotating frames 33 are rotatably sleeved in the mounting chuck assembly 2. A lead screw nut pipe 36 is passed through the rotating frame 33. A lead screw nut pipe 36 is sleeved with a lead screw 361 in the inner thread of one of the lead screw nut pipes 36. A cross-linking rod 362 is fixed between the lower end of the lead screw 361 and the sliding plate 312. A positioning elastic telescopic member 316 is provided on the upper end of the support frame 311. One side of the upper end of the lifting and lowering rod 313 is tilted. The positioning elastic telescopic member 316 is arranged on the upper side of the tilted end of the lifting and lowering rod 313. When the hydraulic telescopic rod assembly 41 contracts, it can drive the L-shaped rod 411 fixed thereto to rise, so that the L-shaped rod 411 can contact the lifting and lowering rod The lower end side of the component 313 can push the sliding plate component 312 to rise. The rising of the sliding plate component 312 can make the cross-linking rod 362 drive the screw component 361 to rise, which can make one of the screw nut pipe components 36 rotate, and can drive the first gear 37 on the screw nut pipe component 36 to rotate. When the lifting top rod component 313 is rising, it will squeeze the positioning elastic telescopic component 316. The positioning elastic telescopic component 316 is composed of a rod body and a spring component. The rod body and the relative end of the lifting top rod component 313 can be hemispherical. The lifting top rod component 313 can rise and contact the hemispherical arc surface, so that it is retracted into the vertical plate component 31. After the lifting top rod component 313 rises, the positioning elastic telescopic component 316 is reset and can contact the lower end of the lifting top rod component 313, thereby realizing the positioning of the cross-linking rod component 362 and the screw component 361, and also moving the U-shaped card 34 into place.

[0034] When the clamping adaptation mechanism 3 needs to release the clamping of the brake disc to be processed, the hydraulic telescopic rod assembly 41 can drive the L-shaped rod 411 to continue to rise, so that the L-shaped rod 411 can push the lifting top rod 313 to rise. The rising of the lifting top rod 313 will drive the arc-shaped card plate linkage member 315 to rise. At the same time, the U-shaped card 34 and the adaptive resistance assembly 35 will further squeeze the brake disc to be processed. Corresponding margins are reserved in the processing design, which can operate stably. When the arc-shaped card plate linkage member 315 rises, the reset spring member 314 will drive the lifting top rod 313 to move away from the L-shaped rod 411. After reaching the corresponding position, the lifting top rod 313 and the L-shaped rod 411 are separated and descended, which can drive the sliding The movable plate member 312 descends, and the screw nut tube member 36 and the first gear 37 rotate in the opposite direction through the cross-link rod member 362 and the screw member 361, so that the U-shaped card 34 drives the adaptive interference component 35 to separate from the brake disc to be processed. At the same time, the arc-shaped card plate linkage member 315 and the lifting push rod member 313 move to the lowest reachable end under the action of the reset spring member 314, and the hydraulic telescopic rod assembly 41 can drive the L-shaped rod member 411 to descend. Because the lower end of the L-shaped rod member 411 and the opposite side of the upper end of the lifting push rod member 313 are both inclined, the lifting push rod member 313 can be squeezed to move it, so that the L-shaped rod member 411 is moved to the lower end of the lifting push rod member 313, so as to facilitate the preliminary clamping of the brake disc to be processed after the next load.

[0035] Among them, an inner gear ring part 38 is fixed at the lower end of the first circular ring 32, and the inner gear ring part 38 extends into the mounting chuck assembly 2. A plurality of first gears 37 are meshed at equal intervals on the inner gear ring part 38. The plurality of first gears 37 are respectively fixedly mounted on a plurality of screw nut tubes 36. The first gear 37 is driven to rotate by one of the screw nut tubes 36, and the inner gear ring part 38 can be rotated by the first gear 37. The rotation of the inner gear ring part 38 causes the plurality of first gears 37 to rotate synchronously, and the plurality of screw nut tubes 36 all rotate. The screw nut tube 36 is connected to a reset telescopic mechanism, and the position of the push rod 394 can be controlled by the reset telescopic mechanism to facilitate the reset of the push rod 394.

[0036] In this embodiment, the resetting telescopic mechanism includes a stretching and telescopic assembly 39, which includes a sleeve member 393, in which a push rod 394 is slidably installed, and a notch 392 is fixed on one end of the push rod 394 located in the sleeve member 393 and on the side wall of one end of the sleeve member 393. A notch 392 is opened on one side of the sleeve member 393, and an opening 396 is opened on the push rod 394. A pull rope 395 is fixed on one end of the opening 396 near the tension spring member 391, and one end of the pull rope 395 passes through the opening. The opening 396 and the notch 392 are connected to a synchronous adjustment mechanism arranged on one side thereof. When the screw nut tube 36 rotates, the screw nut tube 36 can wrap the pull rope 395. The winding can enable the opening 396 to drive the push rod 394 to move, and can push the U-shaped card 34 and the adaptive interference assembly 35 to move toward the center position of the chuck member 21. After the processing is completed, when the external force is reduced, the push rod 394 can be pulled toward the sleeve member 393 through the tension spring member 391 to release the clamping of the brake disc.

[0037] In this embodiment, the interference clamping mechanism includes a plurality of U-shaped cards 34, and the plurality of U-shaped cards 34 are arranged at equal intervals in the mounting chuck assembly 2, the U-shaped card 34 is located in the second notch 26, the U-shaped card 34 is connected to the reset telescopic mechanism, and an adaptive interference assembly 35 is installed in the U-shaped card 34. The operation of the reset telescopic mechanism can enable the U-shaped card 34 to drive the adaptive interference assembly 35 to move. During actual production and preparation, the plurality of adaptive interference assemblies 35 will be staggered with the plurality of supporting plates 43. When the brake disc is placed on the supporting plate 43, the adaptive interference assembly 35 can interfere with and limit the edge of the brake disc.

[0038] The adaptable resistance assembly 35 includes a plurality of elastic telescopic rods 351 installed from top to bottom in the U-shaped card 34. The elastic telescopic rod 351 is composed of a rod body, a sleeve and a spring. The spring is installed in the sleeve, and the rod body slides in the sleeve. At the same time, the rod body resists the spring and the sleeve. When a force is applied, the spring can be compressed, and the disc 352 can move toward the U-shaped card 34. The brake disc has a certain thickness. During production and preparation, the thickness of the disc 352 can be prepared according to actual conditions, which helps to make the thickness of the brake disc be the disc 352. 52 is an integer multiple of the thickness, which makes it easy for the brake disc to contact the corresponding number of disc members 352, so that this part of the disc members 352 is moved toward the U-shaped clamp 34, and the multi-directional adaptive resistance components 35 respectively and evenly spacedly resist the edge of the brake disc, which can achieve the clamping of the edge of the brake disc. At the same time, the elastic telescopic rod 351 can fully ensure the stability of the brake disc position, and can also make the axis of the brake disc overlap with the axis of the chuck member 21, which can effectively limit the brake disc and prevent it from moving up and down, and then clamp the brake disc through the resistance clamping mechanism 5.

[0039] Furthermore, an arc-shaped sliding member 354 is fixed to the piston rod end of the elastic telescopic rod 351, and a disc 352 is provided on one side of the arc-shaped sliding member 354. A circular groove 356 is provided on a peripheral side wall of the disc 352. A plurality of arc-shaped sliding members 354 are respectively slidably installed in the plurality of circular grooves 356. A plurality of second balls 355 are evenly installed at the upper and lower ends of the peripheral side walls of the disc 352. The arc-shaped sliding member 354 can make the disc 352 rotate, and the second balls 355 can also rotate. The second ball 355 can move so as to contact the edge of the brake disc, thereby facilitating the rotation of the brake disc. Two first balls 353 are installed on the upper and lower ends of the disc member 352. The straight-line distance between the two first balls 353 at the upper end of the same disc member 352 is smaller than the straight-line distance between the two first balls 353 at the lower end. The gap between the two first balls 353 at the upper part on the opposite side of two adjacent disc members 352 is large, which can facilitate the movement of the two first balls 353 at the lower end without hindering each other.

[0040] Working principle: by controlling the expansion and contraction of the piston rod of the hydraulic telescopic rod assembly 41, the clamping adaptation mechanism 3, the rotating bearing mechanism 4 and the abutting clamping mechanism 5 can be driven to operate accordingly. When the collar member 42 and the chuck member 21 abut against each other, a rod body is arranged at the lower end of the chuck member 21, and the collar member 42 is sleeved thereon, and the chuck member 21 and the collar member 42 are arranged coaxially. The piston rod of the hydraulic telescopic rod assembly 41 is in the initial position. At this time, the bearing plate 43 and the bearing frame 44 are located at the lower end of the inner hole of the chuck member 21, and the resistance tension spring member 422 provides force to carry the brake disc to be processed. The piston rod of the hydraulic telescopic rod assembly 41 contracts, that is, the hydraulic telescopic rod assembly 41 drives the L-shaped rod 411 to rise, so that the L-shaped rod 411 can resist the lifting top rod 313 to rise and squeeze the positioning elastic telescopic member 316 to achieve the position positioning of the lifting top rod 313. At this time, the sliding plate 312 causes the screw member 361 to rise through the cross-link rod 362, and through a screw nut pipe member 36 and the first gear 37, all the screw nut pipe members 36 and the first gear 37 are rotated under the action of the inner gear ring member 38, pushing the top rod 394, the U-shaped card 34 and the adaptive resistance assembly 35 to move toward the brake disc to be processed, achieving preliminary clamping, and the brake disc to be processed can resist the second ball 355 to rotate; The hydraulic telescopic rod assembly 41 drives the L-shaped rod 411 to descend, and the piston rod of the hydraulic telescopic rod assembly 41 pushes the top plate 423 to drive the collar 42 to descend, so that the collar 42 can drive the contact plate 54 to contact the brake disc to be processed through the oblique push rod 52, and the carrier 44 and the carrier plate 43 are moved out of the inner hole position of the chuck 21, so as to facilitate the processing of both sides of the brake disc to be processed; After the processing is completed, the hydraulic telescopic rod assembly 41 drives the L-shaped rod 411 to rise, and the collar 42 contacts the chuck 21 again, and the carrier 44 and the carrier plate 43 move to the inner hole position of the chuck 21, and the contact plate 54 is separated from the brake disc to be processed; The hydraulic telescopic rod assembly 41 drives the L-shaped rod 411 to continue to rise, so that the L-shaped rod 411 can contact the lifting top rod 313 again and push the lifting top rod 313 to rise again, and the lifting top rod 313 can move away from the L-shaped rod 411 and separate from the L-shaped rod 411 through the action of the reset spring 314, so that the lifting top rod 313 can fall and reset. The falling of the lifting top rod 313 can make the sliding plate 312, the cross-link rod 362, The operation of the lead screw 361 can cause the lead screw nut tube 36 and the first gear 37 to operate in the opposite direction, so that the U-shaped card 34, the adaptive interference assembly 35 and the brake disc are separated, and the brake disc falls on the carrier 44 and the carrier plate 43. The hydraulic telescopic rod assembly 41 drives the L-shaped rod 411 to fall, and the lower end of the L-shaped rod 411 conflicts with the inclined end of the lifting top rod 313, so that the L-shaped rod 411 can move to the lower end of the lifting top rod 313 to clamp the new brake disc to be processed.
