Description

Technical Field

[0001] The present invention relates to the technical field of brake disc jigs, and particularly to a brake disc jig for machining automotive brake discs. Background Art

[0002] The brake disc is an important component in the automotive braking system. When stepping on the brake, it controls the brake caliper to clamp the brake disc to achieve deceleration or stop.

[0003] During the machining of the brake disc, its surface needs to be cut and polished. If the brake disc is not fixed stably, the machining accuracy will be reduced. Existing mechanical grippers have problems such as inaccurate position control, untimely and inconvenient adjustment of the clamping force.

[0004] A brake disc clamping jig with the publication number CN212144547U includes a mounting plate and a frame. The mounting plate is provided on the surface of the frame. One side of the top surface of the mounting plate is fixedly connected with a mounting seat. A servo motor is installed on the right side wall of the top of the mounting seat. A first synchronous pulley is installed on the left side wall of the top of the mounting seat. A second synchronous pulley is provided on the left side of the mounting plate. A coupling is provided on the surface of the mounting plate. A left lead screw is installed on the left side of the coupling, and a right lead screw is installed on the right side of the coupling. The other end of the left lead screw is connected in series with a left lead screw left shaft seat. A left nut is installed in series on one side of the left lead screw left shaft seat. Left guide rails are installed on both sides of the top and bottom of the left lead screw. In this application, position control realizes rapid and accurate positioning, saving time; torque control realizes accurate clamping force to grab the workpiece, improving accuracy; the position and torque size can be changed at any time, and the adjustment is convenient, realizing flexible machining.

[0005] In the above technical solution, a motor is used in cooperation with corresponding supporting components to improve the grasping accuracy, and it is convenient to adjust the position of the brake disc for machining. However, when clamping, the brake disc is generally lifted by an external device into the clamping component for fixation, which cannot ensure the stability of the lifting position of the brake disc. Moreover, due to the contact and collision between components, vibrations or displacements occur, which is even more unfavorable for ensuring that the brake disc is at the center position of the clamping device when being clamped, affecting the clamping effect. Therefore, improvements are needed. Summary of the Invention

[0034] 1. Through the cooperation of the arc-shaped sliding part and the circular groove, the disc part can rotate on its own, and the second ball can also rotate. When the brake disc is clamped by the clamping adaptation mechanism, the brake disc can be adjusted as needed;

[0035] The thickness of the brake disc is the same in the same batch, and the thickness of the brake disc is also specified by standards. 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, 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;

[0037] 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;

[0038] That is, when the collar part and the chuck part are in contact, the bearing plate and the bearing frame operate into the holes in the chuck part, and can carry the brake disc to be processed; after the clamping adaptation mechanism initially clamps the brake disc to be processed, the separation of the collar part and the chuck part can be controlled, which can push the bearing frame and the bearing plate out of the inner hole of the chuck part. At the same time, it can also make the contact clamping mechanism clamp the brake disc to be processed, and effectively expose one side of the brake disc to be processed close to the bearing frame and the bearing plate, so as to process both sides of the brake disc to be processed;

[0039] 4. The first motor drive assembly, the mounting bracket, and the lifting plate can drive the rotating shaft to drive the mounting chuck assembly to lift, and the second motor drive assembly and the rotating shaft can make the mounting chuck assembly drive the brake disc therein to deflect.

An inclined push rod member 52 is universally connected between the second ring 51 and the lower end of the rotating bearing mechanism 4. By pulling the inclined push rod member 52 through the descent of the collar member 42, the second ring 51 can be rotated to achieve the clamping operation. When the collar member 42 rises and contacts the mounting chuck assembly 2, the contact clamping mechanism 5 can release the clamping of the brake disc to be processed. Two inclined rods 53 are rotatably connected to the lower end of the second ring 51. One ends of the two inclined rods 53 located inside the second ring 51 are rotatably connected to contact plates 54. A slide bar 55 is fixed to one side of each of the two contact plates 54. The two slide bars 55 are respectively installed on both sides inside the mounting chuck assembly 2. One end of the slide bar 55 is slidably installed in the first notch 23. At the same time, the staff can control the inclined push rod member 52 to rotate the second ring 51. By rotating the second ring 51, the inclined rods 53 can be gradually rotated to a state parallel to the slide bar 55 on the same side. By rotating the inclined rods 53, the contact plates 54 can move towards the center position of the chuck member 21 under the action of the inclined rods 53 and the slide bars 55, and can contact the edge of the brake disc to be processed located in the inner hole of the chuck member 21, realizing the clamping of the brake disc to be processed.

[0064] In this embodiment, the synchronous adjustment mechanism includes a vertical plate member 31. The vertical plate member 31 is fixed to the lower end of the mounting chuck assembly 2. A first ring 32 is rotatably sleeved in the mounting chuck assembly 2. A lifting groove 311 is installed on one side of the vertical plate member 31. An arc-shaped clamping plate linkage member 315 is slidably installed in the lifting groove 311. The arc-shaped clamping plate linkage member 315 is a plate body with a C-shaped cross-section. A lifting top rod member 313 passes through and is slidably installed therein. A lifting top rod member 313 is slidably installed in the arc-shaped clamping plate linkage member 315. A reset tension spring member 314 is jointly installed between the lifting top rod member 313 and the vertical plate member 31. The reset tension spring member 314 is inclined, and the lower end of the reset tension 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.

[0065] Among them, a sliding plate member 312 is slidably installed on the vertical plate member 31. The lifting top rod member 313 is slidably sleeved in the sliding plate member 312. The lifting top rod member 313 is connected to the rotation bearing mechanism 4. A plurality of rotating frames 33 are rotatably sleeved in the mounting chuck assembly 2. A lead screw nut pipe fitting 36 is provided through the rotating frame 33. A lead screw member 361 is threadedly sleeved in one of the lead screw nut pipe fittings 36. A horizontal connecting rod 362 is jointly fixed between the lower end of the lead screw member 361 and the sliding plate member 312. A positioning elastic telescopic member 316 is installed at the upper end of the vertical plate member 31. One side of the upper end of the lifting top rod member 313 is inclined. The positioning elastic telescopic member 316 is arranged on the upper side of the inclined end of the lifting top rod member 313. When the hydraulic telescopic rod assembly 41 contracts, it can drive the L-shaped rod member 411 fixed thereto to rise, so that the L-shaped rod member 411 can abut against one side of the lower end of the lifting top rod member 313 to push the sliding plate member 312 to rise. Through the rise of the sliding plate member 312, the horizontal connecting rod 362 can drive the lead screw member 361 to rise, so that one of the lead screw nut pipe fittings 36 can rotate, and the first gear 37 on the lead screw nut pipe fitting 36 can be driven to rotate. When the lifting top rod member 313 rises, it will squeeze the positioning elastic telescopic member 316. The positioning elastic telescopic member 316 is composed of a rod body and a spring component. The opposite ends of the rod body and the lifting top rod member 313 can be arranged in a hemispherical shape. The lifting top rod member 313 can rise to abut against the hemispherical arc surface and make it retract into the vertical plate member 31. When the lifting top rod member 313 rises and then, the positioning elastic telescopic member 316 resets and can abut against the lower end of the lifting top rod member 313 to realize the positioning of the horizontal connecting rod 362 and the lead screw member 361, and also make the U-shaped clamp 34 move into place.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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;

[0074] 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;

[0075] After processing, the hydraulic telescopic rod assembly 41 drives the L-shaped rod 411 to rise. At this time, 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. At the same time, the contact plate 54 separates from the brake disc to be processed.

[0076] The hydraulic telescopic rod assembly 41 drives the L-shaped rod 411 to continue rising, which can make the L-shaped rod 411 contact the lifting jack rod 313 again and push the lifting jack rod 313 to rise again. And through the action of the reset spring 314, the lifting jack rod 313 can move away from the L-shaped rod 411 and separate from the L-shaped rod 411, enabling the lifting jack rod 313 to fall and reset. The fall of the lifting jack rod 313 can make the sliding plate 312, the cross-linking rod 362, and the lead screw 361 operate, enabling the lead screw nut pipe 36 and the first gear 37 to operate in the reverse direction, separating the U-shaped clamp 34 and the adaptive contact assembly 35 from the brake disc. 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 contacts the inclined end of the lifting jack rod 313, enabling the L-shaped rod 411 to move to the lower end of the lifting jack rod 313 for clamping a new brake disc to be processed.
