Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, in particular to a reversible tooling fixture for automobile parts processing. Background Art

[0002] There are many types of circular automotive parts. In the engine, the piston is approximately circular, and its reciprocating motion in the cylinder participates in energy conversion, and the round shape ensures sealing; the crankshaft pulley is also round, used to transmit the crankshaft power to auxiliary equipment. In the transmission system, the wheel body of the transmission gear is round, and different gear combinations change the transmission ratio; the drive shaft is a cylinder, which can evenly withstand torque and transmit power. In the driving system, the wheel hub is round, bearing the weight of the vehicle and ensuring stable wheel rotation; the rolling bearing is an overall circular structure to reduce friction. In the braking system, the brake disc is a round metal disc, which provides stable braking force and good heat dissipation when braking; the brake drum is also round, and cooperates with the brake shoe to achieve braking. In addition, the instrument panel dial and the diaphragm of the car audio speaker are also round, used to intuitively display information and evenly transmit sound respectively.

[0003] The Chinese patent with the announcement number "CN211277163U" discloses a fixture for automobile parts with good clamping effect, which includes a support plate, a U-shaped slot is provided at the top of the support plate, a spiral rod 1 is provided through the side of the U-shaped slot, a spiral rod 2 is provided through the other side of the U-shaped slot, a rotating wheel 1 is provided at one end of the spiral rod 1, and a clamping block 1 is provided at the other end of the spiral rod 1. The beneficial effect is: the fixture is used to clamp parts of different models to prevent loosening between parts. Through the action between the fixtures, parts of different models are fixed inside the fixture, so that the parts are fixed more firmly during the processing process and the processed parts are more accurate.

[0004] The above-mentioned device does have certain functional advantages in clamping. However, when clamping a circular workpiece, due to the special shape of the circular workpiece itself, its shape stability is relatively weak. Obviously, if a flat clamp is used to clamp the circular workpiece, then after the clamping is completed, the stability of the workpiece cannot be effectively guaranteed. Moreover, after completing the clamping action, the device lacks the corresponding flipping adjustment function, which means that when it is necessary to process any position on the outer surface of the part, many inconveniences will arise. For example, when polishing a circular part, due to the lack of a flexible reversal adjustment function, the position of the part cannot be flexibly adjusted according to actual needs. It can be seen that from the perspective of overall processing, the device has obvious defects and shortcomings, so it is very necessary to improve it. Utility Model Content

DETAILED DESCRIPTION Example

[0024] refer to Figures 1 to 5 The present embodiment is a reversible fixture for machining automobile parts, comprising a base plate 1, a mounting groove 2 being provided in the middle of the top of the base plate 1, an adjustment mechanism 3 being installed inside the mounting groove 2, clamping mechanisms 6 being fixedly installed on both sides of the top of the adjustment mechanism 3, a support 4 being fixedly installed in the middle of the top of the adjustment mechanism 3, and a placement plate 5 being rotatably connected to the top of the support 4;

[0025] The clamping mechanism 6 includes a mounting plate 61, which is fixedly mounted on both ends of the top of the adjusting mechanism 3. A telescopic cylinder 62 is fixedly mounted on the top of the mounting plate 61, and a shifting assembly 63 is fixedly mounted on the top of the telescopic cylinder 62. The inner side of the shifting assembly 63 is fixedly connected with a clamping assembly 64, and the clamping assembly 64 is arranged in an outward-facing "X" shape. The adjusting mechanism 3 on the mounting plate 631 can be flexibly adjusted. The telescopic cylinder 62 on the mounting plate 61 cooperates well with the shifting assembly 63 and the clamping assembly 64. The outward-facing "X"-shaped clamping assembly 64 can adapt well to circular parts. Through the coordination of the adjusting mechanism 3 and related components, circular parts of different sizes can be centered when clamped, and the adaptability is strong. Moreover, the placing plate 5 is rotatable, and the pillar 4 ensures its stability. During the processing, the parts can be flipped and adjusted by related components, which facilitates the processing of various parts of the parts and improves the comprehensiveness and efficiency of the processing.

[0026] refer to Figure 1-Figure 2The bottom of the placement tray 5 is fixedly installed with a supporting frame 7, and the lower end of the supporting frame 7 is fixedly installed with a collar 8, which is rotatably connected to the outer surface of the pillar 4. The four corners of the base plate 1 are provided with mounting holes 9, and the mounting holes 9 are set as countersunk holes. The supporting frame 7 and the collar 8 at the bottom of the placement tray 5 are reasonably designed. The supporting frame 7 can enhance the stability of the placement tray 5, and the rotating connection between the collar 8 and the pillar 4 allows the placement tray 5 to be flexibly rotated, which is convenient for operating parts at different angles during the processing. The mounting holes 9 at the four corners of the mounting plate 631 are set as countersunk holes, so that the heads of the mounting screws do not protrude from the surface of the mounting plate 631 during installation, which not only ensures the flatness of the mounting surface and avoids interference with the processing process, but also prevents the screw heads from being damaged by collisions, thereby improving the safety and reliability of the overall structure of the fixture.

[0027] refer to Figure 1-Figure 2 The first and second screw rods 32 are connected to each other in a fixed manner so as to prevent the first and second screw rods from rotating.

[0028] refer to Figures 1-4The adjustment component 63 includes a mounting plate 631, which is fixedly mounted on the top of the telescopic cylinder 62. The outer side of the mounting plate 631 is fixedly connected to the second motor 632. The output end of the second motor 632 passes through the mounting plate 631 and is fixedly connected to the side rail 633. The side rail 633 is fixedly mounted on the output end of the second motor 632. One end of the side rail 633 is fixedly connected to the third motor 634. The output end of the third motor 634 passes through the side rail 633 and is fixedly mounted with a second screw rod 635. The second screw rod 635 is rotatably connected to the inside of the side rail 633. The threads at both ends of the second screw rod 635 are rotated in opposite directions. Both ends of the second screw rod 635 are threadedly connected to a movable block 636. The movable block 636 is slidably connected to the inner ends of the side rail 633. The inner side of the movable block 636 is fixedly connected to the clamping component 64. The clamping component 64 includes a clamping frame 641 The clamping frame 641 is fixedly installed on the inner side of the movable block 636, and the two clamping frames 641 on both sides are arranged in an outward-facing "X" shape. The inner side of the clamping frame 641 is evenly spaced and rotatably connected with three transmission guide rollers 642. The mounting plate 631 provides stable support for other components. The second motor 632 can drive the side rails 633 to work, and the third motor 634 drives the second screw rod 635 to rotate. The opposite thread rotation directions at both ends can make the movable block 636 slide in the side rails 633 in the opposite direction, thereby driving the clamping assembly 64 to flexibly adjust the spacing. The outward-facing "X"-shaped clamping frame 641 is uniquely designed and can stably clamp circular parts, and the transmission guide rollers 642 rotatably connected at equal intervals on the inner side of the clamping frame 641 are even more ingenious. During the processing, it can assist the rotation of parts, facilitate the processing of different positions of parts, and make the entire processing process more efficient, flexible and stable.

[0029] refer to Figure 4-Figure 5 , side plates 643 are fixedly installed on both sides of the top of a clamping frame 641, and a worm 644 is rotatably connected to the inner side of the side plate 643. Three worm gears 645 are rotatably connected to the top of the clamping frame 641 with side plates 643. The worm 644 and the worm gear 645 are transmission-connected. The bottom of the worm gear 645 is fixedly connected to the top of the transmission guide roller 642. A fourth motor 646 is fixedly connected to the outer side of a side plate 643. The output end of the fourth motor 646 is fixedly connected to one end of the worm 644. The side plates 643 on both sides of the top of the clamping frame 641 provide stability for the internal structure. A fixed installation foundation is provided, and the worm 644 on the inner side of the side plate 643 is connected to the worm gear 645 at equal intervals. When the fourth motor 646 on the outer side of the side plate 643 drives the worm 644 to rotate, the transmission guide roller 642 can be driven to rotate through the transmission of the worm 644 and the worm gear 645. This design can accurately control the movement of the transmission guide roller 642, so that the clamped parts can be flexibly rotated as needed during the processing, which is convenient for processing different parts of the parts, improving the processing efficiency and accuracy, and has a compact structure and efficient coordination between the components.

[0030] Principle and advantages of use: By setting the adjustment mechanism 3 and the shifting assembly 63 to cooperate with each other, the device can start the first motor 34 during use of the device, and its power drives the first screw rod 32 to start rotating. The rotation of the first screw rod 32 will cause the slider 33 to slide on the inner side of the guide rail 31. Because the thread rotation directions of the two ends of the first screw rod 32 are opposite, as the first screw rod 32 rotates, the slider 33 will move synchronously in opposite directions at both ends of the guide rail 31. The mutual displacement of the slider 33 can flexibly drive the clamping frame 641 in the clamping assembly 64 to move relative to each other. At this time, the clamping frames 641 in the shape of an outward eight move relative to each other, and they can stably The second screw rod 635 is rotated by the third motor 634. Since the threads at both ends of the second screw rod 635 rotate in opposite directions, the second motor 634 can assist in driving the two movable blocks 636 to make the clamping frames 641 further move relative to each other, so that the spacing between the clamping frames 641 can be synchronously adjusted. Through these designs, the device as a whole has the ability to flexibly clamp and position circular parts of different sizes, and its clamping adaptability is very strong.

[0031] After completing the clamping of the circular part, the device starts the fourth motor 646. During the processing, the fourth motor 646 can drive the worm 644 to rotate. The rotation of the worm 644 will drive the worm wheel 645 to start rotating. The rotation of the worm wheel 645 can assist in driving the transmission guide roller 642 inside the clamping frame 641 to start rotating. Because the transmission guide roller 642 and the outer arc surface of the circular part are in contact with each other, as the transmission guide roller 642 rotates, it can assist in driving the circular part into a rotating state. In this way, the position of the circular part can be flexibly adjusted during the processing, which is convenient for comprehensive processing of the top and outer surface of the circular part. If the bottom of the part needs to be processed, it is only necessary to start the telescopic The cylinder 62 pushes the clamping assembly 64 to move upward, and the parts clamped on the clamping assembly 64 will also move upward. Then, the second motor 632 is started to drive the side rail 633 to flip, so that the clamped circular parts can be flipped and adjusted. After the flipping adjustment is completed, the telescopic cylinder 62 retracts and the parts can be placed on the top of the placement tray 5 again. Through these operations, it can be seen that this device can comprehensively process the outer surfaces of circular parts of different sizes during the processing. Moreover, during the processing, the placement tray 5 can be rotated, and a support frame 7 and a ring 8 are provided at the bottom. These components can assist in supporting the processing placement tray 5, thereby improving the overall stability of the device during the production and processing process.
