Description

Technical Field

[0001] This utility model relates to the field of piston rod grinding equipment technology, and in particular to a piston rod grinding device with a dust removal mechanism. Background Technology

[0002] The piston rod grinding device is a special equipment used for surface grinding of piston rods. The piston rod is fixed on the grinding device by a mounting base to ensure its stability during the grinding process.

[0003] The existing utility model patent with announcement number CN211728809U discloses a dust removal mechanism for a piston rod grinding device. Although this utility model patent solves the problem that the existing piston rod grinding device does not have a dust removal function, resulting in a large amount of dust being generated when the piston rod is being ground, causing workers to inhale the dust for a long time, which is harmful to the workers' health and inconvenient for workers to use.

[0004] However, the vacuum cleaner, mounting mechanism, suction pipe, and suction hood in this equipment are in fixed positions, and cannot move with the blade to remove dust while the blade is grinding the piston rod. When the blade is far from the vacuum cleaner, the dust removal effect is insufficient, and workers still have the risk of inhaling dust, which can harm their health. In addition, the equipment is equipped with a water replacement pipe, water replacement valve, water tank, and filtration mechanism. Since the piston rod has already undergone rough machining before grinding, the amount of dust generated during grinding is small. The addition of a filtration mechanism to each grinding unit increases the equipment cost. Utility Model Content

[0005] In order to reduce the cost of piston rod grinding equipment while ensuring the dust removal effect of the grinding equipment, this application provides a piston rod grinding device with a dust removal mechanism.

[0006] The piston rod grinding device with a dust removal mechanism provided in this application adopts the following technical solution:

[0007] A piston rod grinding device with a dust removal mechanism includes a base plate.

The support frame is located above the fixed frame. The pressing cylinder is connected to the top of the support frame. The movable frame is connected to the piston rod of the pressing cylinder, which passes through the end of the support frame. The movable frame is also arranged in an inverted "U" shape. The pressing roller is connected to the movable frame. There are two pressing rollers corresponding to the drive rollers. The drive rollers and pressing rollers can be clamped at the end of the piston rod.

[0009] Preferably, the drive assembly includes a bearing housing, a threaded rod, a nut seat, a guide rod, a mounting plate, and a drive motor.

[0010] Preferably, the sidewall of the dust collection hood is slidably attached to the inner wall of the dust baffle.

[0011] Preferably, the dustproof plate has an observation port, and an acrylic plate is connected inside the observation port.

[0012] Preferably, a gap is left between the end of the dust baffle and the fixed frame in the clamping mechanism to allow dust to be discharged.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This utility model provides a piston rod grinding device with a dust removal mechanism. The dust collection hood and the grinding disc move synchronously through a drive component and a lifting cylinder, ensuring that the device remains close to the dust source during grinding, shortening the dust collection distance, effectively reducing the risk of dust escape, and significantly reducing the health hazards of workers inhaling dust. The dust baffle partially surrounds the piston rod and forms a partially sealed space with the sliding dust collection hood, limiting the dust diffusion path. Combined with the negative pressure adsorption of an external dust extraction device, the dust collection effect is further enhanced, thereby achieving the goal of reducing the cost of piston rod grinding equipment while ensuring the dust removal effect of the grinding equipment.

[0022] The dust collection hood 6 and the grinding disc 413 move synchronously through the drive component 5 and the lifting cylinder 41, ensuring that they are always close to the dust source during the grinding process, shortening the dust collection distance, effectively reducing the risk of escape, and significantly reducing the health hazards of workers inhaling dust. The dust baffle partially surrounds the piston rod and forms a local sealed space with the sliding dust collection hood 6, limiting the dust diffusion path. Combined with the negative pressure adsorption of the external dust extraction equipment, the dust collection effect is further enhanced.

[0023] The clamping assembly 2 includes a fixed frame 21, drive rollers 22, pulleys 23, a track 24, a rotary motor 25, a support frame 26, a pressing cylinder 27, a movable frame 28, and a pressing roller 29. The fixed frame 21 is connected to the base plate 1 and is U-shaped. Two drive rollers 22 are connected to the fixed frame 21 and are arranged parallel to each other. The pulleys 23 are connected to the roller shafts of the drive rollers 22. The track 24 is wound between the two pulleys 23. The rotary motor 25 is mounted on the base plate 1. The output shaft of 5 is coaxially connected to the roller shaft of one of the drive rollers 22 via a coupling. The support frame 26 is connected to the base plate 1. The support frame 26 is arranged in an inverted "U" shape and is located above the fixed frame 21. The pressing cylinder 27 is connected to the top of the support frame 26. The movable frame 28 is connected to the piston rod of the pressing cylinder 27, which passes through the end of the support frame 26. The movable frame 28 is arranged in an inverted "U" shape. The pressing roller 29 is connected to the movable frame 28. There are two pressing rollers 29 corresponding to the drive rollers 22.

[0028] The implementation principle of the piston rod grinding device with a dust removal mechanism in this application embodiment is as follows: During operation, the piston rod is placed on the drive roller 22, and then the downward pressing cylinder 27 pushes the movable frame 28 and the downward pressing roller 29 to descend. The downward pressing roller 29 and the drive roller 22 cooperate to clamp the piston rod. Then, the piston rod is driven to rotate by the joint cooperation of the rotating motor 25, the pulley 23, and the track 24. During grinding, the lifting cylinder 41 lowers the grinding disc 413 so that it abuts against the surface of the piston rod. Then, the grinding motor 412 drives the grinding disc 413 to rotate, and at the same time, the drive motor 56 drives the threaded rod 52 to rotate. The nut seat 53 can move along the length direction of the threaded rod 52 under the guidance and limiting action of the guide rod 54, thereby driving the grinding disc 413 to move along the piston rod, and the piston rod rotates to perform comprehensive grinding on the surface of the piston rod.
