Description

Technical Field

[0001] This utility model relates to the field of floating seal ring technology, and in particular to an automatic pressing mechanism for floating seal rings. Background Technology

[0002] The floating seal ring is one of the components of the floating ring seal. The floating ring can float freely in the housing, so the impact on the seal is small when the shaft rotates at high speed and vibrates. Friction and wear are also very small. During the assembly of the floating ring seal, the floating seal ring needs to be pressed into the wheel body.

[0003] A search revealed a Chinese patent (application number "202122572167.3") disclosing "a wheel body floating seal ring press-fitting fixture." This press-fitting fixture includes a sleeve, a handle, and a press head. The sleeve includes a pressure-applying end and a working end, with the diameter of the pressure-applying end being larger than the diameter of the working end. The handle is fixed to the pressure-applying end. The press head is disc-shaped and has a central hole. The press head is fitted onto the working end through the central hole. The working end is also used to hold the floating seal ring to be installed. However, the above press-fitting fixture has the following problems during use:

[0004] 1. When pressing the floating seal ring, the floating seal ring is fitted onto the outer wall of the working end. When the whole thing is lowered, the floating seal ring slips off and causes the floating seal ring to be misaligned with the wheel body, resulting in pressing failure and low work efficiency.

[0005] 2. When pressing the floating seal ring, the wheel body is not fixed, and it needs to be manually fixed, which reduces its practicality. Utility Model Content

[0006] This utility model provides an automatic pressing mechanism for a floating seal ring, which solves the problems of the floating seal ring slipping off when the comparison document descends, causing the floating seal ring and the wheel to be misaligned, resulting in pressing failure, low work efficiency, and low practicality due to the lack of wheel fixation and the need for manual wheel fixation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automatic pressing mechanism for a floating seal ring includes a base frame. A floating seal ring support assembly is located at the top of the base frame. The support assembly includes a support base with three slide rails on its top outer wall, a support block with three limiting grooves on its top outer wall, and two fixing plates respectively fixed to the top outer wall of the base frame. A positioning assembly is located below the support blocks. The positioning assembly includes an adjusting motor bolted to the inner wall of the top of the base frame, an adjusting disc with three sets of adjusting grooves on its top outer wall, three sliding rods slidably installed in the three adjusting grooves, three sliding blocks slidably installed in the three slide rails, and three positioning rods slidably installed in the three limiting grooves. The support block is equipped with a limiting assembly, which includes a limiting plate with a slot on the top outer wall, four connecting blocks respectively screwed to the outer walls of the two sides of the limiting plate, four limiting rods fixed to the top outer wall of the bottom frame, and four return springs respectively sleeved on the outer walls of the four limiting rods. The bottom of the limiting plate is equipped with two clamping assemblies, which include a clamping cylinder and a clamping plate bolted to the outer wall of one end of the piston rod of the clamping cylinder. The top of the bottom frame is equipped with a pressing assembly, which includes a top plate, a servo cylinder bolted to the top outer wall of the top plate, and a pressing block bolted to the outer wall of the bottom end of the piston rod of the servo cylinder.

[0009] Preferably, two support plates are fixed on the top outer wall of the bottom frame, and the bottom of the support base is fixed on the top outer wall of the two support plates respectively.

[0010] Preferably, the adjusting disc is bolted to the outer wall of the top of the output shaft of the adjusting motor, and the adjusting disc abuts against the outer wall of the bottom of the support plate. The slider is fixed to the outer wall of the top of the sliding rod, and the positioning rod is fixed to the outer wall of the top of the slider.

[0011] The above scheme involves adjusting the motor output shaft to drive the adjustment disc to rotate, which in turn causes the slide rod to slide along the arc-shaped adjustment groove. Simultaneously, the slider moves along the slide rail, and the positioning rod moves along the limit groove, causing the three positioning rods to contact the inner wall of the floating seal ring, thereby positioning the floating seal ring.

[0012] Preferably, each of the two fixing plates has two channels on one outer wall, and four connecting blocks are slidably installed in the four channels. The four connecting blocks are slidably installed on the outer walls of the four limiting rods, and the four connecting blocks abut against the outer walls of the top ends of the four reset springs.

[0013] Preferably, two mounting seats are fixed on the bottom outer wall of the limiting plate, and the clamping cylinder is bolted to one side of the outer wall of the mounting seat. A rubber pad is fixed on one side of the outer wall of the clamping plate.

[0014] The above method secures the wheel in the slot, with the annular groove on the outer wall of the wheel abutting against the outer wall of the top of the limiting plate. Then, the piston rods of the two clamping cylinders move the clamping plates, causing the two clamping plates to contact and fix the outer wall of the wheel.

[0015] Preferably, a mounting plate is fixed on one side of the outer wall of the bottom frame, and a top plate is fixed on the upper outer wall of one side of the mounting plate. Two support rods are fixed on the bottom outer wall of the top plate, and the two support rods are respectively fixed on the top outer wall of the bottom frame.

[0016] The above scheme involves the servo cylinder piston rod descending to drive the pressing block to descend, which then presses the floating seal ring in the space above the wheel body. Subsequently, the limiting plate drives the four connecting blocks to descend and presses the four return springs. The descending wheel body presses the floating seal ring on the support block, causing the two floating seal rings to respectively engage in the upper and lower spaces of the wheel body. Then, the servo cylinder piston rod returns to its original position, and the limiting plate returns to its original position under the tension of the four return springs, lifting the wheel body and causing it to detach from the support block.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. It is equipped with a floating seal ring support assembly and a positioning assembly. The output shaft of the adjusting motor drives the adjusting plate to rotate. The adjusting plate drives the slide rod to slide along the adjusting groove of the arc structure. At the same time, the slider moves along the slide rail, and the positioning rod moves along the limiting groove, so that the three positioning rods contact the inner wall of the floating seal ring, thereby positioning the floating seal ring. This positioning of the floating seal ring can prevent the floating seal ring from moving during pressing and causing pressing failure, thus improving work efficiency.

[0019] 2. A limiting component and a clamping component are provided to hold the wheel in the slot. The annular groove on the outer wall of the wheel abuts against the outer wall of the top of the limiting plate. Then, the piston rods of the two clamping cylinders drive the clamping plates to move, so that the two clamping plates contact and fix the outer wall of the wheel. This can limit and clamp the wheel. There is no need to manually fix the wheel during press-fitting, which improves practicality.

[0020] In summary, this utility model can position the floating seal ring, prevent the floating seal ring from moving and causing pressing failure during pressing, thus improving work efficiency. It can also limit and clamp the wheel body, eliminating the need for manual fixing of the wheel body during pressing, thereby improving practicality. Attached Figure Description

The adjustment disc 302 abuts against the outer wall of the bottom of the support plate 201. The adjustment slots have an arc-shaped structure. The sliders 303 are cubic and have a larger outer diameter than the slide rods 303. The sliders 304 are fixed to the outer wall of the top of the slide rods 303, and the positioning rods 305 are fixed to the outer wall of the top of the sliders 304.

[0031] Example 2, refer to Figure 1-2 and Figure 5-6 An automatic pressing mechanism for a floating seal ring further includes a limiting component 4. The limiting component 4 includes a limiting plate 401 with a slot on its top outer wall, four connecting blocks 402 respectively screwed to the outer walls of both sides of the limiting plate 401, four limiting rods 403 fixed to the top outer wall of the base frame 1, and four return springs 404 respectively sleeved on the outer walls of the four limiting rods 403. The inner diameter of the slot is adapted to the inner diameter of the annular groove of the wheel body to be pressed. By replacing the limiting plate 401 and support block 203 with different slot specifications, floating seal rings and wheels of different specifications can be pressed. Two channels are opened on one outer wall of each of the two fixing plates 204. Each connecting block 402 is slidably installed in one of the four channels. Each of the four connecting blocks 402 is slidably installed on the outer wall of the four limiting rods 403. Each of the four connecting blocks 402 abuts against the outer wall of the top of the four return springs 404. The bottom of the limiting plate 401 is provided with two clamping assemblies 5. Each clamping assembly 5 includes a clamping cylinder 502 and a clamping plate 503 which is bolted to the outer wall of one end of the piston rod of the clamping cylinder 502. Two mounting seats 501 are fixed on the bottom outer wall of the limiting plate 401. The clamping cylinder 502 is bolted to one outer wall of the mounting seat 501.

[0033] Working principle: The output shaft of the adjusting motor 301 drives the adjusting disc 302 to rotate. The adjusting disc 302 drives the sliding rod 303 to slide along the adjusting groove of the arc structure. At the same time, the slider 304 moves along the slide rail, and the positioning rod 305 moves along the limiting groove, so that the three positioning rods 305 contact the inner wall of the floating seal ring, thereby positioning the floating seal ring and locking the wheel body in the slot. The annular groove on the outer wall of the wheel body abuts against the outer wall of the top of the limiting plate 401. Then, the piston rods of the two clamping cylinders 502 drive the clamping plate 503 to move, so that the two clamping plates 503 contact the outer wall of the wheel body and advance... The wheel body is fixed in place. The piston rod of the servo cylinder 604 descends, causing the pressing block 605 to descend. The pressing block 605 presses the floating seal ring in the space above the wheel body. Then, the limiting plate 401 drives the four connecting blocks 402 to descend and press the four return springs 404. The wheel body descends and presses the floating seal ring on the support block 203, so that the two floating seal rings are respectively stuck into the upper and lower spaces of the wheel body. Then, the piston rod of the servo cylinder 604 returns to its original position, and the limiting plate returns to its original position under the tension of the four return springs 404, and lifts the wheel body, so that the wheel body is separated from the support block 203.
