Description

Technical Field

[0001] The utility model belongs to the technical field related to brake production, and particularly relates to a brake disc spraying suspension device. Background Art

[0002] The brake disc is a metal disc made of alloy steel and fixed on the wheel, rotating with the wheel. When the vehicle is driving, the brake caliper clamps the brake disc to slow down or stop the vehicle. Generally, there are round holes on the brake disc, which is used to reduce weight and increase friction. There are many types of brake discs, which are characterized by thin walls and sand cores on the disc and the center. After the brake disc is roughly formed, it is generally sprayed to form a certain coating on its surface (such as anti-corrosion coating), but it still has the following disadvantages in the actual spraying process:

[0003] Because brake discs are mostly produced in large quantities, they are mostly sprayed in assembly line mode. Therefore, it is necessary to have a carrier that can hold the brake discs in batches and move them in assembly line mode to support them. However, most of the current processes are to place the brake discs one by one and then spray them, which is inefficient.

[0004] Secondly, in order to meet the requirements of efficient assembly line operation, the spraying position usually cannot be changed too much. This requires the brake disc to have high flexibility after being supported so that it can be sprayed quickly and evenly. Utility Model Content

[0005] The utility model aims to provide a suspension device for spraying a brake disc. By setting a main shaft, a cross beam, a secondary shaft, a suspension rod, a support rod and an adjusting ring block, a suspension device is used to suspend the brake disc, and a suspension track is used for transportation, thereby solving the problems of being unable to place brake discs in batches and maintain assembly line movement, insufficient flexibility of the brake discs after being supported, and being unable to quickly change the range for rapid spraying.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a brake disc spray suspension device, comprising a main shaft, a cross beam, a secondary shaft, a suspension rod and an adjusting ring block, the bottom end of the main shaft is rotatably connected to the center of the upper surface of the cross beam, both ends of the bottom surface of the cross beam are rotatably connected to the secondary shaft, the bottom of the secondary shaft is threadedly connected to the suspension rod, three hinged parts distributed in a ring array are fixed on the outer peripheral surface of the lower part of the suspension rod, and each hinged part is hingedly connected to a support rod, the outer sliding sleeve of the support rod is provided with an adjusting ring block, three traction ropes distributed in a ring array are fixed to the bottom surface of the adjusting ring block, and the bottom end of each traction rope is connected to a connecting piece;

[0008] A sliding groove is provided on the peripheral side surface of the upper part of the support rod. The connecting member includes an external sphere connected to the traction rope and an internal sphere located in the inner cavity of the support rod. A connecting rod is connected between the external sphere and the internal sphere.

[0009] Furthermore, a mounting plate is fixed to the upper end of the main shaft, and mounting holes for bolts to pass through are provided at the four corners of the mounting plate.

[0010] Furthermore, a handwheel is fixed on the outer periphery of the lower part of the secondary shaft, a screw hole is opened in the secondary shaft, and the screw hole passes through the bottom end of the secondary shaft, an external thread is opened on the upper outer periphery of the suspension rod, and the suspension rod is screwed into the screw hole through the external thread and fixed to the secondary shaft thread.

[0011] Furthermore, a through limiting groove is provided in the suspension rod below the external thread, a limiting block is fixed in the inner cavity of the adjusting ring block, and the limiting block passes through the limiting groove.

[0012] Furthermore, a limiting ring is fixed in the middle of the suspension rod, the adjusting ring block is located above the limiting ring, and the limiting ring is located below the limiting groove.

[0013] Furthermore, the external sphere is located outside the support rod, and the connecting rod connecting the external sphere and the internal sphere moves in the sliding groove.

[0014] The utility model has the following beneficial effects:

[0015] The utility model provides a crossbeam, a secondary shaft, a suspension rod, a support rod, and an adjusting ring block, adopts a suspension device to suspend the brake disc, and utilizes a suspension track for transportation, thereby solving the problem that the brake discs cannot be placed in batches and maintained in assembly line-like movement; a main shaft is rotatably installed on the crossbeam, and the upper end of the main shaft is connected to the suspension track through a mounting plate, so that the entire suspension device can be transported under the suspension track, realizing assembly line-like transportation operations, and can be paused for a certain period of time at the spraying point; when the brake disc is suspended and supported, the adjusting ring block outside the suspension rod is moved upward, and the support rod is pulled to move by a traction rope and a connecting piece, and the internal sphere in the connecting piece moves in the inner cavity of the support rod, so that the support rod is retracted with the hinge shaft as the center, forming a Figure 2 In the state shown, the brake disc is inserted upward from the bottom of the suspension rod until the brake disc exceeds the height of the support rod, and then the adjusting ring block is loosened, and the support rod returns to its original state (such as Figure 1 As shown), the brake disc is in a horizontal state, and then the brake disc can be stably placed on the support rod for spraying (as shown Figure 3 , 4 as shown).

[0016] The utility model solves the problem of insufficient flexibility of the brake disc after being supported and inability to quickly change the range for rapid spraying by arranging a main shaft, a secondary shaft, a suspension rod and a support rod. Because most of the spraying points will not move, after the brake disc is placed on the support rod for support, the secondary shaft can be rotated under the crossbeam, thereby causing the suspension rod to rotate, so that the brake disc supported on the support rod rotates and produces self-rotation, so that the brake disc can be evenly sprayed. Subsequently, the crossbeam is rotated to allow the brake disc suspended on another group of suspension rods to perform the above-mentioned spraying operation. After completion, it moves along the hanging rail to carry out the spraying operation of the brake disc on the next group of suspension devices. The whole process is highly flexible, can be sprayed quickly, and is highly efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The main shaft 1 is generally stationary, the crossbeam 2 can rotate under the main shaft 1, and the secondary shaft 3 can also rotate independently under the crossbeam 2, and the suspension rod 4 connected to the secondary shaft 3 is rotated together, and the suspension rod 4 is connected to the support rod 401 through a hinge 402. The support rod 401 can be retracted and released for use when placing the brake disc. By adjusting the up and down sliding of the ring block 5, the support rod 401 is pulled by the traction rope 501 and the connecting piece 502 to rotate in an articulated manner, so that the support rod 401 can be retracted and released. When the support rod 401 is released and in a horizontal state, it is used to support the brake disc (such as Figure 3 , 4 state);

[0032] A sliding groove 4011 is provided on the upper peripheral side surface of the support rod 401. The connecting member 502 includes an external sphere 5021 connected to the traction rope 501 and an internal sphere 5022 located in the inner cavity of the support rod 401. A connecting rod 5023 is connected between the external sphere 5021 and the internal sphere 5022.

[0033] The outer sphere 5021 is located outside the support rod 401, and the connecting rod 5023 connecting the outer sphere 5021 and the inner sphere 5022 is movable in the slide groove 4011;

[0034] When the adjusting ring block 5 and the traction rope 501 move upward, the inner ball 5022 moves in the inner cavity of the support rod 401. At this time, the connecting rod 5023 moves in the slide groove 4011, gradually moving from the end of the support rod 401 to the center of the support rod 401, and the outer ball 5021 moves along the outside of the slide groove 4011 until the support rod 401 is retracted (such as Figure 2 as shown), which is convenient for placing the brake disc.

[0039] When the adjusting ring block 5 slides up and down, in order to prevent itself from rotating, a limiting block 503 passing through the limiting groove 403 is installed in its inner cavity, so that the adjusting ring block 5 can be limited and can only slide up and down along the suspension rod 4 without rotating.

[0040] A limiting ring 405 is fixed in the middle of the suspension rod 4, the adjusting ring block 5 is located above the limiting ring 405, and the limiting ring 405 is located below the limiting groove 403;

[0041] The limiting ring 405 is used to support the adjusting ring block 5 to prevent the adjusting ring block 5 from continuing to drop after the supporting rod 401 is horizontal. When the adjusting ring block 5 contacts the limiting ring 405 and is supported, the supporting rod 401 is just horizontal.

Figure 1 As shown), it is in a horizontal state, and then the brake disc can be stably placed on the support rod 401 for spraying treatment;

[0043] During spraying, the secondary shaft 3 is rotated by the hand wheel 301, thereby driving the secondary shaft 3 and the suspension rod 4 to rotate, and then the brake disc is rotated to facilitate spraying. Subsequently, the cross beam 2 is rotated to allow the brake discs suspended on another set of suspension rods 4 to undergo the above-mentioned spraying operation. After completion, the brake discs on the next set of suspension devices are moved along the hanging rail to undergo spraying operation.
