Description

Technical Field

[0001] The utility model relates to the field of clutch assembly, in particular to an assembly device of a clutch driven disc spring and a spring seat. Background Art

[0002] When assembling the existing dry friction clutch driven disc assembly for automobiles, a rubber hammer is usually used to knock the spring part into the driven disc window of the driven disc assembly to achieve the requirements of vibration reduction and noise reduction. Since the spring is assembled in the driven disc part window, the spring and the driven disc part are in direct contact, and the driven disc part is usually tempered and heat treated with a hardness of 28-32HRC. Once used for a long time, it is easy to wear, which will affect the life of the driven disc parts and springs. In severe cases, it will cause spring breakage, excessive wear of the driven disc and other failure modes, making the vehicle unable to be used normally. For this reason, a design that can effectively protect the driven disc parts and springs has emerged, that is, adding a spring seat in the driven disc part window.

[0003] However, after adding the spring seat part design, the boss cylinder on the spring seat part needs to be pre-installed in the inner diameter of the spring part. At the same time, the structure of the spring seat part and the driven plate assembly is a mosaic structure. It is impossible to manually give enough pre-tightening force to keep the assembly in a compressed state, so it cannot be stuck into the driven plate window. Therefore, it is necessary to design a special tooling fixture, which is beneficial to semi-automatic production, improve production capacity, and solve the problem of manual assembly. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and to provide a clutch driven plate assembly spring and spring seat assembly device, which can pre-assemble the spring and spring seat in a free state and put them into a tooling position, place the driven plate assembly on the corresponding tooling position, and push the top block part from the fixture position into the window of the driven plate assembly through the lower cylinder. At the same time, the upper cylinder on the equipment pushes the equal height column and the upper positioning plate to prevent the spring and spring seat assembly from not being in place.

[0006] A table plate is fixed on the frame, and a top plate is supported above the table plate;

[0007] Two sets of linear guide rails are arranged on both sides of the table. A pressing block is slidably arranged on each set of linear guide rails. The two pressing blocks face each other and form a pre-assembly groove at the relative positions of the two blocks for placing the pre-assembled spring and spring seat. Each pressing block is pushed by a set of pushing components to adjust the width of the pre-assembly groove.

[0008] The lower positioning component is fixed on the platen and is used to support and position the driven disk, so that the sector window on the driven disk is aligned with the pre-assembly groove;

[0009] The upper positioning component is arranged on the top plate and moves up and down relative to the lower positioning component, and is used to press the driven disk against the lower positioning component; and

[0010] The jacking component is arranged below the pre-assembly groove and is used to push the pre-assembled spring and spring seat from the pre-assembly groove into the sector window of the driven disk.

[0011] As a further technical solution, the pressing block is in a "C" shape, and a clamping groove is opened at each of the upper and lower ends of each pressing block. The pre-assembly groove is composed of the clamping grooves of the left and right two pressing blocks and the space above the jacking component.

[0012] As a further technical solution, the inner space of the two pressing blocks forms a sliding groove, and at least one in-place stop block is arranged in the sliding groove and is used to limit the sliding stroke of the pressing block along the linear guide rail; the in-place stop block is fixed on the platen.

[0013] As a further technical solution, the lower positioning component includes a lower positioning fixing plate fixed on the platen and a lower positioning fixed on the lower positioning fixing plate, and the lower positioning fixing plate is located in the sliding groove.

[0014] As a further technical solution, a cover plate is arranged above the pressing block, and the cover plate is supported on the platen, so that the pre-assembly groove, the lower positioning and the lower positioning fixing plate are all exposed from the surface of the cover plate.

[0015] As a further technical solution, the upper positioning component includes an upper air cylinder fixed on the top plate, a connecting plate driven by the output end of the upper air cylinder, and an upper positioning arranged below the connecting plate. Linear bearings are installed on the top plate on both sides of the upper air cylinder, and the guide shaft passes through the linear bearings and is connected to the connecting plate. The lower end of the connecting plate is connected to the upper positioning fixing plate through two second equal-height columns. The upper positioning is fixed on the lower surface of the upper positioning fixing plate, and the upper positioning is in a card slot fit with the lower positioning; the top plate is supported on the platen through several third equal-height columns.

[0016] As a further technical solution, the propulsion component includes an oil cylinder fixing plate fixed on the platen and an oil cylinder installed on the oil cylinder fixing plate, and the oil cylinder piston rod is connected to drive the pressing block.

[0017] As a further technical solution, the jacking component includes a stop block fixed on the platen, a top block penetrating through the stop block, and a lower air cylinder arranged below the top block. The stop block is located between two groups of linear guide rails. The lower air cylinder is installed on the air cylinder fixing plate, and the air cylinder fixing plate is fixed to the bottom of the platen through two first equal-height columns. The lower air cylinder piston rod is connected to drive the top block, so that the top block sequentially penetrates through the platen and the stop block and extends into the pre-assembly groove.

[0018] A clutch driven disc assembly spring and spring seat assembly process, using the clutch driven disc assembly spring and spring seat assembly device, the driven disc center is provided with a center hole, four fan-shaped windows are evenly provided along the circumferential direction outside the center hole, and spring seat positioning grooves are provided at the two side edges of each fan-shaped window, comprising the following steps:

[0019] Step 1: After pre-assembling two sets of springs and spring seats into a spring seat assembly, place them into two pre-assembly grooves accordingly;

[0020] Step 2: Align the center hole of the driven plate and place it on the lower positioning plate, so that each pre-assembly groove corresponds to a fan-shaped window. The upper cylinder is activated to drive the upper positioning plate to move downward until the upper positioning plate matches the lower positioning plate, so that the driven plate is pressed tightly against the lower positioning fixing plate.

[0021] Step 3: The oil cylinder is actuated to push the two pressure blocks from both sides toward the center, so that the spring seat assembly is gradually compressed until the pressure blocks are limited by the stoppers in place;

[0022] Step 4: The lower cylinder moves, driving the top block to pass through the stopper and enter the pre-assembly groove, and pushing the spring seat assembly into the corresponding fan-shaped window on the driven plate;

[0023] Step 5: The upper cylinder moves again, loosens the driven plate, and manually rotates the driven plate to align the two fan-shaped windows that are not equipped with spring seat assemblies with the pre-assembly grooves. Repeat steps 1 to 4 to assemble the spring seat assemblies in all four fan-shaped windows.

[0024] As a further technical solution, in the step one, the spring is in a released state in the pre-assembly groove; in the step three, when the pressure block is limited by the stop block in place, the spring is compressed to be shorter than the length of the fan-shaped window; in the step four, after the spring seat assembly is pushed into the driven disk, the spring seat is snapped into the spring seat positioning groove.

[0025] The beneficial effects of the utility model are:

[0027] 2. A stopper is arranged at the slide groove inside the pressing block to limit the stroke of the pressing block. After the pressing block is in place, the spring is compressed to a length shorter than the fan-shaped window, so that it is easy to push into the fan-shaped window later.

[0028] 3. A top block is provided below the pre-assembly groove, which can automatically push the compressed spring seat assembly into the fan-shaped window of the driven plate;

[0029] 4. Two (one group) spring seat assemblies can be assembled at one time. After manually rotating the driven plate, the next group of spring seat assemblies can be assembled automatically, which is beneficial to semi-automatic production, improves production capacity, and solves the problem that cannot be assembled manually.

The stopper 23 is arranged between two sets of linear guide rails 8, and the lower cylinder 6 is installed on the cylinder fixing plate 5. The cylinder fixing plate 5 is fixed to the bottom of the table 1 through two first equal-height columns 3. The piston rod of the lower cylinder 6 is connected to drive the lift block 4, so that the lift block 4 passes through the table 1 and the stopper 23 in sequence and then extends into the pre-assembly groove 31.

[0045] This embodiment also provides a clutch driven disc assembly spring and spring seat assembly process, using the clutch driven disc assembly spring and spring seat assembly device, such as Figure 7 As shown, a center hole 28 is formed in the center of the driven disk 25, and four fan-shaped windows 29 are evenly formed outside the center hole 28 along the circumferential direction. A spring seat positioning groove 30 is formed at the two side edges of each fan-shaped window 29.

[0046] The assembly process includes the following steps:

[0047] Step 1: After pre-assembling two sets of springs 26 and spring seats 27 into a spring seat assembly, they are placed into two pre-assembly grooves 31 respectively. At this time, the length of the pre-assembly groove 31 is greater than the length of the fan-shaped window 29, and the spring 26 is in a released state in the pre-assembly groove 31;

[0048] Step 2: Align the center hole 28 of the driven plate 25 and place it on the lower positioning plate 12, so that each pre-assembly groove 31 corresponds to a fan-shaped window 29 (a total of two fan-shaped windows 29 with an angle of 180°), and then the upper cylinder 20 is actuated to drive the upper positioning plate 13 to move downward until the upper positioning plate 13 cooperates with the lower positioning plate 12, so that the driven plate 25 is pressed against the lower positioning fixing plate 22;

[0049] Step 3: The oil cylinder 9 is actuated to push the two pressing blocks 2 from both sides toward the center, so that the spring seat assembly is gradually compressed until the pressing blocks 2 are stopped by the stopper 24. At this time, the spring 26 (pre-assembly groove 31) is compressed to a length shorter than the fan-shaped window 29.

[0050] Step 4: The lower cylinder 6 moves, driving the top block 4 to pass through the stopper 23 and enter the pre-assembly groove 31, pushing the spring seat assembly into the corresponding fan-shaped window 29 on the driven plate 25, so that the spring seat 27 is stuck in the corresponding spring seat positioning groove 30;

[0051] Step 5: The upper cylinder 20 moves again, loosens the driven disk 25, and manually rotates the driven disk 25 (the rotation angle is 180°) to align the two fan-shaped windows 29 that are not equipped with the spring seat assembly with the pre-assembly groove 31, and repeats steps 1 to 4 to assemble the spring seat assembly in the four fan-shaped windows 29.

[0052] The utility model uses a special tooling fixture to pre-assemble the spring and the spring seat in a free state and put them into the tooling position, puts the driven plate assembly on the corresponding tooling position, and pushes the top block part from the fixture position into the window of the driven plate assembly through the lower cylinder. At the same time, the upper cylinder on the equipment pushes the equal height column and the upper positioning plate to prevent the spring and spring seat assembly from not being in place. The equipment is beneficial to semi-automatic production, improves production capacity, and solves the problem that it cannot be assembled manually.
