Description

Technical Field

[0001] The invention belongs to the technical field of buffer block assembly, and in particular relates to a buffer block automatic assembly device and method. Background Art

[0002] The buffer block is a rubber product with high elasticity and toughness. When producing gear products, the buffer block is assembled on the gear to buffer mechanical vibration and maintain the relative stability of mechanical operation. The buffer block is an inverted assembly groove on the gear.

[0003] There are two main buffer block assembly methods used in the prior art, one of which is to use a cylinder as a power source to drive a cone or a clamp to expand the O-ring, and then put the O-ring onto the structure of the O-ring to be assembled, such as an O-ring assembly clamp device disclosed in the patent with announcement number CN105798579B, and an O-ring assembly device disclosed in the patent with announcement number CN215903048U. Among them, the size of the O-ring after expansion cannot be maintained stably, that is, the outer diameter of the buffer block after expansion is larger than the outer diameter of the groove to be assembled, or the inner diameter of the buffer block after expansion is smaller than the inner diameter of the groove to be assembled, and the buffer block cannot be installed in the groove to be assembled. Another assembly method is to pre-install the buffer block into the groove to be assembled of the gear product, and then use a roller to roll the buffer block into the groove to be assembled. This assembly method causes uneven pressure on the buffer block, and the defective gear products obtained reach 20%. Summary of the invention

[0004] The invention provides a buffer block automatic assembly device and method, which are used to solve the problem of high defective gear products.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: an automatic assembly device for a buffer block, comprising a fixed bracket, a plurality of clamping claws, a driving structure for driving the plurality of clamping claws to open and close to prop up the buffer block, a stripping piece, a stripping block lifting structure, and a buffer block positioning piece;

[0006] The stripping member comprises a stripping outer ring and a stripping inner ring constituting a partial ring body of the stripping outer ring, and the clamp passes through the stripping inner ring;

[0007] The buffer block positioning piece is recessed downward from the vertical direction to form a first positioning groove that passes through both sides, and the stripping outer ring part is embedded in the first positioning groove;

[0008] The buffer block positioning piece is recessed inward from its side wall to form a second positioning groove that passes through from top to bottom. The projection shape of the second positioning groove in the vertical direction is consistent with the projection shape of the groove to be assembled in the vertical direction. The stripping inner ring is used for the clamping jaw to pass through, and the buffer block in the expanded state is pressed into the groove to be assembled along the second positioning groove.

[0009] Specifically, both sides of the first positioning groove extend upward to form a mounting portion, and extend downward to form a limiting portion, and the lower end of the buffer block positioning piece fits with the upper end of the gear.

[0010] Specifically, the driving structure includes a driving cylinder, a support block with an outer diameter gradually increasing from bottom to top, and a plurality of slide rails arranged around the support block, the slide rails are opened on the fixed bracket, each of the slide rails is slidably connected to a slider, the slider is fixedly connected to the clamp, one end of the slider is provided with a roller rollingly connected to the support block, and the other end is provided with an elastic structure, and the elastic structure pushes the slider to move toward the support block after deformation so that the roller abuts against the support block.

[0011] Specifically, the roller includes a double-ear plate, a wheel axle rotatably connected to the double-ear plate, and a wheel body fixed on the wheel axle, and a self-locking ring is sleeved on the wheel axle, and the self-locking ring is used to limit the roller from rolling along the surface of the support block. When the buffer block is stripped, the driving cylinder has insufficient tension on the buffer block, and the buffer block shrinks, resulting in the inner diameter of the buffer block after being stretched smaller than the inner diameter of the groove to be assembled, and the buffer block cannot be aligned with the notch of the groove to be assembled. The self-locking ring fixes the slider and the support block relatively, ensuring that the tension provided to the buffer block is continuous and stable, so that the buffer block will not shrink.

[0012] Specifically, the self-locking ring has an opening, and at least two notches are formed on the inner side of the ring body.

[0013] Specifically, the stripping block lifting structure includes a lifting cylinder that pushes the stripping piece to move up and down in a vertical direction.

[0014] Specifically, the buffer block positioning piece is fixedly connected with an inclined plate, and the inclined plate can move in a vertical direction.

[0015] Specifically, the fixing bracket is provided with double positioning holes, and the inclined plate is provided with double positioning rods, and the double positioning rods are plugged into the double positioning holes in a one-to-one correspondence.

[0016] Specifically, it also includes a gear positioning member, which includes a positioning shaft inserted into the gear shaft hole and an auxiliary shaft that limits the rotation of the gear. A positioning spring is sleeved on the positioning shaft. After the gear is lifted up, the positioning spring buffers it, and the positioning shaft and the auxiliary shaft position it to prevent the gear from being abnormally damaged.

[0017] A method for automatically assembling a buffer block comprises the following steps:

[0018] S1: The plurality of clamps are closed and inserted into the hole in the middle of the buffer block after passing through the stripping inner ring;

[0019] S2: The driving structure drives the plurality of clamping jaws to move away from each other, and the buffer block is spread open;

[0020] S3: The gear feeding structure conveys the gear to be installed with the buffer block to the bottom of the buffer block positioning piece and lifts it upward;

[0021] S4: The stripping block lifting structure drives the stripping piece to move downward, and the stripping piece pushes the buffer block to move downward, and the buffer block moves downward along the second positioning groove to the groove to be assembled;

[0022] S5: The stripping piece moves upward and the clamp closes.

[0023] The technical solution provided by the present invention has the following advantages compared with the prior art:

[0024] 1. Set the buffer block positioning piece to limit the expansion range of the buffer block. Remove the inner ring and then press the buffer block into the corresponding notch of the gear by flat pressing. The buffer block and the notch are precisely docked. The buffer block is evenly stressed when pressed in, and the defective rate of gear products is reduced to 0.2%.

[0025] 2. Use the inner ring of the stripper to avoid the clamping claw, use the outer ring of the stripper to avoid the buffer block positioning piece, then use the second positioning groove to position the buffer block, and the first positioning groove to position the stripper. During the assembly process of the buffer block, the relative positions of the clamping claw, the stripper and the buffer block positioning piece in the non-vertical direction are fixed. During the assembly process, only relative lifting and lowering movements are required, which simplifies the assembly structure, improves the speed and accuracy of the buffer block assembly, and further improves the docking accuracy between the buffer block and the groove to be assembled.

[0045] like Figure 5 As shown, the buffer block opening structure 2 includes a plurality of clamping jaws 21 and a driving structure for driving the plurality of clamping jaws 21 to open and close so as to open the buffer block 5 .

[0046] like Figure 6 As shown, the driving structure includes a driving cylinder 22 and a support block 23. The driving cylinder 22 is fixedly installed on the L-shaped slide plate. The top end of the gas rod of the driving cylinder 22 is fixedly connected to the top plate 11. A support block guide hole 141 is opened in the middle of the bottom plate 14. A support block 23 that can be lifted and lowered relative to the support block guide hole 141 is placed in the support block guide hole 141. The driving cylinder 22 is fixedly connected to the bottom of the top plate 11. The output end of the driving cylinder 22 is connected to the L-shaped slider 19. Four slide rails 24 are arranged around the support block guide hole 141. The four slide rails 24 are all opened on the lower surface of the bottom plate 14. A matching block 25 is arranged at one end of the slide rail 24 away from the support block guide hole 141. The matching block 25 is fixedly installed on the bottom plate 14 by a bolt 16. Each slide rail 24 is correspondingly slidably connected to a slider 26, and each slider 26 is correspondingly fixedly connected to a clamp 21.

[0047] Continue as Figure 6 As shown, the outer diameter of the support block 23 increases gradually from bottom to top. Specifically, the upper end thereof is a flat plate for providing a mounting hole to fix the L-shaped slider 19, and the lower end is a column. The column is divided into three sections from bottom to top. The first section and the third section are both quadrangular prisms. The size of the first section quadrangular prism is smaller than that of the second section quadrangular prism. The second section is a quadrangular pyramid.

[0048] Continue as Figure 6 As shown, the clamping jaw 21 has a top portion fixedly connected to the ring body, a middle portion extending downward from the top portion close to one end of the support block 23 and avoiding the support block 23 , and clamping teeth for inserting into the middle fan-shaped hole 51 of the buffer block 5 .

[0049] like Figure 7As shown, a protruding double-ear plate 261 is provided at one end of the slider 26 facing the guide hole 141 of the support block, and the double-ear plate 261 is provided with a hole, in which a wheel axle 262 is inserted, and the wheel axle 262 can rotate relative to the double-ear plate 261 and will not separate from the double-ear plate 261, and a wheel body 263 is fixedly connected to the wheel axle 262 between the double-ear plates 261;

[0050] like Figure 6 As shown, a blind hole 265 for guiding a spring 266 is provided at one end of the slider 26 which is away from the guide hole 141 of the support block. A spring 266 is placed in the blind hole 265. One end of the spring 266 abuts against the bottom of the blind hole 265, and the other end abuts against the matching block 25. After deformation, the spring 266 is used to push the wheel body 263 against the outer surface of the support block 23.

[0051] like Figure 7 As shown, a self-locking ring 264 is sleeved on the wheel axle 262 on one side of the double-ear plate 261. The self-locking ring 264 is used to limit the roller from rolling along the surface of the support block 23, so that the buffer block 5 will not shrink when removing the material. Specifically, the self-locking ring 264 has an opening, and at least two notches are opened on the inner side of the ring body. After the wheel body 263 rotates a certain amplitude, the opening contacts the surface of the support block 23, and the inclined surface of the surface of the support block 23 is arranged to abut the ring body at the opening of the self-locking ring 264. The inner notch of the self-locking ring 264 clamps the wheel axle 262, limiting the wheel body 263 from rolling relative to the surface of the support block 23, thereby achieving the purpose of self-locking. When the buffer block 5 is stripping the material, the driving cylinder 22 has insufficient tension on the buffer block 5, and the buffer block 5 shrinks, resulting in the inner diameter of the buffer block 5 after being stretched being smaller than the inner diameter of the groove 61 to be assembled. The buffer block 5 cannot be aligned with the notch of the groove 61 to be assembled, and the self-locking ring 264 fixes the slider 26 and the support block 23 relatively to ensure that the tension provided to the buffer block 5 is continuous and stable, and the buffer block 5 will not shrink.

As the support block 23 moves downward, the slider 26 moves along the slide rail 24 in the direction away from the support block guide hole 141, and the four clamps 21 are relatively far away from each other, the buffer block 5 is opened, the spring 266 is compressed, and the self-locking ring 264 clamps the wheel axle 262. After the buffer block 5 is completely separated from the clamp 21, the support block 23 moves up, and the spring 266 pushes the slider 26 to move toward the support block guide hole 141. The wheel axle 262 rotates in the opposite direction, and the four clamps 21 return to the closed state.
