Description

Technical Field

[0001] The invention relates to the technical field of vehicle assembly, and in particular to a clamping and transmission device on an assembly line. Background Art

[0002] The wheel hub is a cylindrical metal part that supports the tire with its inner profile. It is usually installed on the axle and is mainly used to support and fix the tire and transmit power. Although the traditional steel wheel hub is strong, it is heavy, so it is gradually replaced by aluminum alloy wheel hub. Aluminum alloy wheel hub has the advantages of light weight, beautiful appearance, good heat dissipation, good vibration resistance, etc. It not only makes the vehicle more fuel-efficient, but also has a longer service life.

[0003] In the prior art, during the vehicle assembly process, the wheel hub conveyed on the assembly line needs to be manually pushed from a horizontal position to a vertical position for subsequent installation. Although the weight of the aluminum alloy wheel hub is relatively light, a single wheel hub weighs about 10 kg. After working for a long time, not only is the labor intensity high, but overwork may also cause damage to the wheel hub. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention proposes a clamping and transmission device on an assembly line, which can help workers stand up the transported wheel hub.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a clamping and transmission device on an assembly line, comprising a conveying line, a clamping component and a flipping component;

[0006] The clamping assembly comprises a clamping block, and two clamping blocks are symmetrically arranged on both sides of the conveying line and can move towards each other;

[0007] The turnover assembly comprises a mounting seat, two mounting seats are rotatably arranged on both sides of the conveying line, and the clamping block is arranged on the mounting seat.

[0008] The wheel hub is transported forward on the conveyor line. When passing through the clamping assembly, the clamping blocks move toward each other to clamp the wheel hub. Then the mounting seat rotates, driving the clamping blocks and the clamped wheel hub to rotate, thereby standing the wheel hub on the conveyor line.

[0009] The beneficial effect of the clamping and transmission device on the above-mentioned assembly line is that the hub on the conveyor line can be erected through the cooperation of the clamping component and the flipping component, thereby greatly saving the work intensity of the workers and avoiding bumps.

[0010] Furthermore, the clamping assembly also includes a push rod, one end of which is connected to the mounting seat through a cylinder, and the other end of which is connected to the clamping block.

[0011] The cylinder drives the push rod to extend and retract, so that the clamping block can clamp or release the wheel hub.

[0012] Furthermore, a side of the clamping block away from the push rod is arc-shaped.

[0013] The curved side of the clamp can better fit the wheel hub.

[0014] Furthermore, guide plates are provided on both sides of the conveying line along the conveying direction, and the guide plates are provided with gradually rising guide chutes along the conveying direction;

[0015] The flip assembly also includes a rack, which is fixedly arranged on the side of the guide plates away from each other. A sliding column is provided on the side of the mounting seat away from the clamping block. The sliding column is movably arranged in the guide slot and is provided with a gear meshing with the rack.

[0016] The slide column of the mounting seat can move in the guide slot, and as the guide slot gradually rises, the mounting seat also drives the clamping block and the wheel hub to gradually rise. At the same time, with the cooperation of the gear and the rack, the slide column drives the mounting seat to rotate, thereby driving the clamping block and the wheel hub to rotate, and finally erecting the wheel hub on the conveyor line.

[0017] Furthermore, the mounting seat and the gear are respectively attached to two sides of the guide plate.

[0018] The mounting seat and the gear can limit the sliding column so that the sliding column can only slide in the guide groove and cannot move to the two ends.

[0019] Furthermore, the flip assembly also includes a hydraulic cylinder and a propulsion block. The hydraulic cylinder is fixedly arranged on one side of the guide plate away from each other and is connected to the propulsion block. A strip hole is opened on the propulsion block in the vertical direction, and the slide column is rotatably and slidably connected in the strip hole.

[0020] The thrust cylinder drives the thrust block to move axially, so as to push the slide column to move in the guide slot. Meanwhile, the slide column gradually rises in the guide slot, that is, moves upward in the strip hole of the thrust block.

[0021] Furthermore, it also includes a positioning component, including baffle 1 and baffle 2, wherein baffle 1 and baffle 2 are movably arranged above the conveyor line and can accommodate a single wheel hub therebetween, and baffle 1 and baffle 2 extend toward both sides of the conveyor line respectively and can move reciprocatingly toward both sides of the conveyor line.

[0022] When the wheel hub on the conveyor line reaches the positioning assembly, it is first blocked by baffle 2, and then baffles 1 and 2 move toward one side of the conveyor line, so that a wheel hub moves between baffles 1 and 2, and baffles 1 and 2 move toward the other side of the conveyor line, so that the wheel hub can continue to be transported forward. Thus, a single material is fed each time, so that the clamping assembly and the flipping assembly can stand up the wheel hub.

[0023] Furthermore, the positioning assembly also includes a connecting rod, a rotating drum, a motor and a groove wheel mechanism. The baffle plate 1 and the baffle plate 2 are both connected to one end of the connecting rod. The rotating drum is rotatably arranged, and two symmetrical spiral grooves are opened on the surface along the axial direction. The two ends of the two spiral grooves are connected to each other. The other end of the connecting rod is slidably connected to the spiral groove, and the motor is connected to the rotating drum through the groove wheel mechanism.

[0024] The motor drives the drum to rotate periodically and intermittently through the grooved wheel mechanism. Under the action of the spiral groove, the drum can drive the connecting rod to move back and forth intermittently, thereby intermittently conveying a single wheel hub to the clamping assembly and the flipping assembly.

[0025] Furthermore, the clamping block can clamp the wheel hub between baffle plate 1 and baffle plate 2.

[0026] Whenever a wheel hub is fed between baffle plate 1 and baffle plate 2, the wheel hub is clamped by the clamping block to ensure that the clamping assembly can accurately clamp the wheel hub. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0037] See also Figures 1 to 3 The present invention provides a clamping and transmission device on an assembly line, including a conveyor line 10, a clamping assembly 20 and a flipping assembly 30. The clamping assembly 20 can clamp the hub on the conveyor line 10 and then stand it up through the flipping assembly 30, thereby saving the physical strength of the workers.

[0038] Specifically, the clamping assembly 20 includes clamping blocks 21, two clamping blocks 21 are symmetrically arranged on both sides of the conveying line 10, and can move toward each other to clamp the wheel hub. The flipping assembly 30 includes a mounting seat 31, two mounting seats 31 are rotatably arranged on both sides of the conveying line 10, and the clamping blocks 21 are arranged on the mounting seats 31.

[0039] The wheel hub is conveyed forward on the conveyor line 10. When it passes through the clamping assembly 20, the two clamping blocks 21 move toward each other to clamp the wheel hub from both sides. Then the mounting seat 31 rotates, driving the clamping blocks 21 and the clamped wheel hub to rotate, so that the wheel hub can be erected on the conveyor line. Workers are no longer required to carry it, which not only saves physical strength but also avoids bumps.

[0040] In this embodiment, the clamping assembly 20 further includes a push rod 22, one end of which is connected to the mounting seat 31 through a cylinder, and the other end is connected to the clamping block 21. The cylinder drives the push rod 22 to extend and retract, so that the clamping block 21 can clamp or release the wheel hub. In addition, the side of the clamping block 21 away from the push rod 22 is arc-shaped, which can be more convenient to fit with the wheel hub.

[0041] Specifically, the flip assembly 30 further includes a guide plate 32 and a rack 322. The guide plates 32 are provided on both sides of the conveying line 10 along the conveying direction, and the guide slots 321 which are gradually raised are provided along the conveying direction. The rack 322 is fixedly arranged on the side of the guide plates 32 which are away from each other, and a slide column 33 is provided on the side of the mounting seat 31 which is away from the clamping block 21. The slide column 33 is movably arranged in the guide slot 321 and is provided with a gear 331 which can mesh with the rack 322.

[0042] The slide post 33 of the mounting seat 31 can move in the guide slot 321, and as the guide slot 321 gradually rises, the clamping block 21 and the wheel hub are also gradually raised. Then, under the cooperation of the gear 331 and the rack 322, the slide post 33 drives the mounting seat 31 to rotate, thereby driving the clamping block 21 and the wheel hub to rotate, and finally the wheel hub is erected on the conveyor line. In this embodiment, the specific trajectory of the slide rail is to rise first, so as to lift the clamped wheel hub first, and only after it is lifted to a certain height, the gear 331 meshes with the rack 322, driving the wheel hub to rotate, and the rotated wheel hub is suspended on the conveyor line. Then the slide rail is slightly lowered to place the wheel hub on the conveyor line.

[0043] The mounting seat 31 and the gear 331 are respectively attached to the two sides of the guide plate 32 , which can limit the position of the slide column 33 , so that the slide column 33 can only slide in the guide slot 321 and cannot move to the two ends.

[0044] Specifically, the flip assembly 30 further includes a hydraulic cylinder 34 and a push block 35. The hydraulic cylinder 34 is fixedly arranged on a side of the guide plate 32 that is away from each other and is connected to the push block 35. A strip hole 351 is provided on the push block 35 in the vertical direction, and the slide column 33 is rotatably and slidably connected in the strip hole 351. The push cylinder can drive the push block 35 to move axially to drive the slide column 33 to move in the guide slot 321. When the slide column 33 gradually rises in the guide slot 321, it moves upward in the strip hole 351 of the push block 35. When the slide column 33 rotates under the action of the gear 331 and the rack 322, it rotates in the strip hole 351.

[0045] Specifically, it also includes a positioning assembly 40, including a baffle plate 1 41 and a baffle plate 2 42. The baffle plates 1 41 and 42 are movably arranged above the conveyor line 10, and the height is different from that of the clamping assembly 20 to avoid interference. The two baffle plates can block the top of the hub, and the clamping assembly 20 can clamp the lower half of the hub. The baffle plates 1 41 and 42 are arranged along the conveying direction, and a single hub can be accommodated therebetween. The baffle plates 1 41 and 42 extend toward both sides of the conveyor line 10, respectively, and can reciprocate toward both sides of the conveyor line 10.

[0046] When the wheel hub on the conveyor line 10 reaches the positioning assembly 40, it is first blocked by the baffle 2 42, and then the baffle 1 41 and the baffle 2 42 move toward one side of the conveyor line 10, and the side where the baffle 2 42 extends, so that a wheel hub moves between the baffle 1 41 and the baffle 2 42, and the baffle 1 41 and the baffle 2 42 move toward the other side of the conveyor line 10. First move to the neutral position, the subsequent wheel hub is blocked by the baffle 2 42, the wheel hub to be fed is blocked by the baffle 1 41, and the clamping assembly 20 clamps the wheel hub. Then move toward the direction in which the baffle 1 41 extends, and at this time, the baffle 1 41 no longer blocks the blocked wheel hub, and it can be transported forward. The baffle 1 41 and the baffle 2 42 repeat the previous steps, and the wheel hubs can be fed in sequence and orderly, so that the clamping assembly 20 and the flip assembly 30 can stand up the wheel hubs in sequence.

[0047] like Figure 3 As shown, the positioning assembly 40 also includes a connecting rod 43, a rotating drum 44, a motor 45 and a groove wheel mechanism 46, which are used to drive the movement of the baffle 1 41 and the baffle 2 42. This part is located at a position higher than the conveyor line, so it is Figure 3 Schematic diagram. One end of the connecting rod 43 is connected to both the baffle 1 41 and the baffle 2 42. The rotating drum 44 is rotatably arranged, and two symmetrical spiral grooves 441 are opened on the surface along the axial direction. Both ends of the two spiral grooves 441 are connected to each other, and the other end of the connecting rod 43 is slidably connected in the spiral groove 441. The motor 45 is connected to the rotating drum 44 through the groove wheel mechanism 46. With the cooperation of the groove wheel mechanism 46, the rotating drum 44 can be driven to rotate periodically and intermittently. When the rotating drum 44 rotates, the spiral groove 441 can drive the connecting rod 43 to move back and forth intermittently, thereby intermittently conveying a single wheel hub to the clamping assembly 20 and the flipping assembly 30. In this embodiment, since the baffle 1 41 and the baffle 2 42 have four travel sections when feeding and receiving materials, the groove wheel mechanism 46 adopts a groove wheel with a four-groove structure. Since the groove wheel mechanism 46 is a common prior art, it will not be described in detail.

[0048] In addition, the clamp block 21 can clamp the wheel hub between the baffle plate 1 41 and the baffle plate 2 42. When the wheel hub is positioned, the clamp block 21 can clamp the wheel hub to center the wheel hub and stand it up with the cooperation of the flip assembly 30. This method does not require sensors for identification, saving costs.

[0049] The working principle of the clamping and transmission device on the above assembly line is as follows: when the wheel hub is transported on the conveyor line 10 and passes through the positioning assembly 40, the motor 45 drives the baffle plate 1 41 and the baffle plate 2 42 to move reciprocatingly toward both sides, and the wheel hub is fed one by one in sequence and in an orderly manner. Under the action of the cylinder, the two clamping blocks 21 clamp and fix the feeding wheel hub, and then the hydraulic cylinder 34 pushes the slide column 33 to move in the guide slide groove 321 through the propulsion block 35, so that the mounting seat 31 drives the clamping block 21 and the wheel hub to gradually rise, and after rising to a certain height, the gear 331 meshes with the rack 322, and the slide column 33 drives the clamping block 21 and the wheel hub to rotate, so that the wheel hub can be erected on the conveyor line.

[0050] The use of the above-mentioned clamping and transmission device on the assembly line can help workers arrange the wheel hubs on the conveyor line in an orderly manner and stand them up on the conveyor line to facilitate the next step of assembly, which greatly saves the workers' physical strength and can avoid bumps, thereby ensuring the quality of the wheel hubs.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
