Description

Technical Field

[0001] The utility model relates to the field of turning fixtures, in particular to a turning fixture for processing sealing rings. Background Art

[0002] The sealing ring is an annular sealing part with a notch. It presses against the inner hole wall of the stationary part to seal due to its elasticity after being pressed together. When the sealing ring is turned, it needs to be clamped with a fixture.

[0003] At present, a Chinese utility model with the announcement number CN215920210U discloses a sealing ring fixing fixture, including a base, a cylinder is installed below the base through a bracket, the cylinder piston rod is vertically arranged upward and penetrates the base, and a lifting seat is fixed on the top of the cylinder piston rod; a plurality of slide grooves are arranged on the base in a circular array with the lifting seat as the center, a matching slider is arranged in the slide groove, a clamping block is fixed on the upper end of the slider, and the bottom of the clamping block is in contact with the end face of the base; hinge supports are arranged on the outer wall of the lifting seat and the clamping block in a one-to-one correspondence, and also includes a connecting rod, and the two ends of the connecting rod are respectively hinged to the two hinge supports arranged on the lifting seat and the corresponding clamping block. Since the stroke of the four clamping blocks is consistent, the utility model can realize self-centering and improve the processing accuracy. At the same time, it can meet the fixing and clamping needs of sealing rings of various specifications, and has a wide applicability.

[0004] To sum up, although the device can meet the needs of fixing and clamping sealing rings of various specifications, there are still certain problems in its use. For example, the adjustment structure of the device adopts a cylinder and a connecting rod to adjust the position of the clamping seat. Although the purpose of adjustment can be achieved, the lifting amplitude of the cylinder is different for sealing rings of different sizes during adjustment. The cylinder needs to be adjusted for each size of sealing ring, which is troublesome to adjust. In addition, the use of the cylinder has high production costs and is more energy-consuming when used, and the purpose of energy saving cannot be achieved. At the same time, the clamp can only achieve the purpose of clamping and clamping the inner ring of the sealing ring. During turning, only the outer ring of the sealing ring can be turned. When the inner ring of the sealing ring needs to be turned, the clamp cannot clamp the outer ring of the sealing ring, and the convenience is poor. Utility Model Content

[0005] The utility model aims to provide a turning fixture for sealing ring machining, which has the advantages of strong applicability, low cost and strong convenience.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a turning fixture for sealing ring processing, comprising a fixed seat, a sliding groove is provided on the top of the fixed seat, the number of the sliding grooves is four, the interior of the sliding groove is rotatably connected with a screw rod through a bearing, a clamping seat is provided on the top of the screw rod, an inner groove is provided inside the fixed seat, one end of the screw rod passes through the interior of the inner groove and is fixedly sleeved with a first bevel gear, a second bevel gear used in conjunction with the first bevel gear is provided inside the inner groove, a fixed block is provided inside the clamping seat, a pressure block is symmetrically bolted on the fixed block, and an adjusting bolt threadedly connected to the fixed block is rotatably connected to the interior of the clamping seat through a bearing.

[0007] By adopting the above technical scheme, the utility model provides a sliding groove on the fixed seat. When the rotating disk rotates, it drives the screw to rotate, and the screw drives the first bevel gear to rotate. Under the action of the second bevel gear, the other three first bevel gears rotate, so that the four screws rotate at the same time. Under the action of the connecting block, the positions of the four clamping seats are adjusted at the same time, which improves its applicability and does not require the use of cylinders, thereby reducing production costs and energy consumption. By installing a fixed block on the adjusting seat and a pressure block on the fixed block, the sealing ring can be placed on the outer layer of the four clamping seats or between the four clamping seats. When the fixed block is driven downward by the adjusting bolt, the pressure block presses the sealing ring, so that the clamp can be suitable for outer ring processing and inner ring processing of the sealing ring, without the need to use other clamps, thereby improving processing convenience and applicability.

[0008] The utility model is further configured as follows: a connecting block is threadedly connected to the surface of the screw rod, and the top of the connecting block is bolted to the bottom of the clamping seat.

[0009] The above technical solution is adopted to facilitate the movement of the clamping seat.

[0010] The utility model is further configured as follows: the connecting block is symmetrically bolted with sliding blocks, and the interior of the sliding groove is provided with a sliding groove used in conjunction with the sliding block.

[0011] The above technical solution is adopted to slide and limit the connection block.

[0012] The utility model is further configured as follows: a threaded hole groove is opened on the top of the fixing seat, and the number of the threaded hole grooves is four.

[0013] The above technical solution is adopted to facilitate the installation and positioning of the fixing seat.

[0014] The utility model is further configured as follows: a rotating disk is arranged on the surface of the fixing seat, and the rotating disk is fixedly sleeved with one end of the screw rod.

[0015] The above technical solution is adopted to facilitate driving the screw rod to rotate.

[0016] The utility model is further configured as follows: guide blocks are symmetrically bolted on the fixing block, and guide grooves used in conjunction with the guide blocks are provided inside the clamping seat.

[0017] The above technical solution is adopted to perform sliding limiting on the fixed block.

[0018] The utility model is further configured as follows: a connecting plate is arranged on the top of the clamping seat, and the connecting plate is fixedly sleeved with one end of the adjusting bolt.

[0019] The adoption of the technical solution makes it convenient to rotate the adjusting bolt.

[0020] The utility model is further configured as follows: a connecting shaft is fixedly sleeved at the center of the second bevel gear, and the connecting shaft is rotatably connected to the fixing seat through a bearing.

[0021] The above technical solution is adopted to facilitate the rotation limiting of the second bevel gear.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The utility model has a sliding groove on the fixed seat. When the rotating disk rotates, the screw rod is driven to rotate, and the screw rod drives the first bevel gear to rotate. Under the action of the second bevel gear, the other three first bevel gears rotate, so that the four screw rods rotate at the same time. Under the action of the connecting block, the positions of the four clamping seats are adjusted at the same time, which improves its applicability and does not require the use of cylinders, thereby reducing production costs and energy consumption;

[0024] 2. The utility model has a fixed block installed on the adjusting seat, and a pressure block installed on the fixed block, so that the sealing ring can be placed on the outer layer of the four clamping seats or between the four clamping seats. When the fixed block is driven downward by the adjusting bolt, the pressure block presses the sealing ring, so that the clamp can be suitable for the outer ring processing and the inner ring processing of the sealing ring, without the use of other clamps, thereby improving the convenience and applicability of processing.
