Abstract
The utility model discloses a knurling device of inner wall of a seal groove. The knurling device comprises a clamping device, a roller shaft and a knurl wheel, wherein the clamping device is connected with a numerically-controlled machine tool. The knurling device is characterized in that one end of the roller shaft is inserted in the interior of the clamping device and is axially positioned with the clamping device, and the other end of the roller shaft is axially connected with the knurl wheel; the knurl wheel can turn round freely around the roller shaft. The knurling device has the advantages that the knurl wheel and the squeezing amount of the surface of the inner wall of the seal groove are adjusted through the numerically-controlled machine tool, and the clamping device is controlled to drive the roller shaft and the seal groove to perform a relative motion; the knurl wheel turns round passively under the effect of the roller shaft; embossing is formed on the surface of the inner wall of the seal groove through a gear wheel of the knurl wheel, so that knurling on the inner wall of the seal groove with relatively narrow width is realized.
Description
Technical field
The utility model relates to a kind of Knurling device, especially a kind of seal groove inwall Knurling device.
Background technology
Shipping industry is the modern comprehensive industry that technical equipment is provided for industries such as water transportation, ocean development and national defense construction, also be work, capital-and technology-intensive enterprise, marine product designing requirement height, make and require precision, the technical merit tip, quality of fit between each parts or sealed precision must reach requirement, and good sealing effectiveness has been played in the design of the inwall annular knurl of planar annular seal groove in practice.But, because the narrower in width of seal groove can't be carried out the annular knurl operation with traditional cylindrical knurling tool and method, process very difficult.
Summary of the invention
The utility model purpose is: a kind of seal groove inwall Knurling device is provided, and not only simple in structure, and be applicable to the seal groove inwall annular knurl that width is narrower.
The technical solution of the utility model is: a kind of seal groove inwall Knurling device, comprise clamping device, roller shaft and knurled wheel, this clamping device is connected with Digit Control Machine Tool, it is characterized in that, described roller shaft one end insert described clamping device inner and with this clamping device axial location, the described roller shaft other end axially is connected with described knurled wheel, and this knurled wheel can freely turn round around roller shaft.
Further, described clamping device and described roller shaft adopt interference fit and radially fixing by screw.
Further, the roller shaft of described roller shaft for adopting low-carbon alloy steel to make.
Further, the knurled wheel of described knurled wheel for adopting high-speed tool steel to make.
The utility model has the advantages that: adjust the amount of compression of knurled wheel and seal groove inner wall surface and control clamping device drive roller shaft and seal groove relative motion by Digit Control Machine Tool, knurled wheel is done passive revolution under the roller shaft effect, the gear of this knurled wheel forms embossing in the seal groove inner wall surface simultaneously, thereby is implemented in annular knurl on the narrower seal groove inwall of width.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the utility model seal groove inwall Knurling device cutaway view;
Wherein: 1 clamping device, 2 roller shafts, 3 knurled wheels, 4 screws.
The specific embodiment
Embodiment: with reference to shown in Figure 1, a kind of seal groove inwall Knurling device, comprise clamping device 1, roller shaft 2 and knurled wheel 3, clamping device 1 is connected with Digit Control Machine Tool, this clamping device 1 and Digit Control Machine Tool be connected and motion mode is prior art, known to those skilled in the art, roller shaft 2 one ends insert clamping device 1 inner and with this clamping device 1 axial location, roller shaft 2 other ends axially are connected with knurled wheel 3, and this knurled wheel 3 can freely turn round around roller shaft 2, and this clamping device 1 adopts interference fit and radially fixing by screw 4 with roller shaft 2; Clamping device 1 adopts 45 forging to make, and the turning moulding has enough intensity, rigidity; Roller shaft 2 adopts low-carbon alloy steel to make, and grinds moulding, nitrogencase hardening, and hardness reaches 55HRC, has both guaranteed that there are enough hardness and abrasion resistance in the roller shaft surface, guarantees that again roller shaft has enough toughness, should not rupture; Knurled wheel 3 adopts high-speed tool steel to make, and obtains by the numerical control electric spark processing method, and its gear has high hardness.
The utility model has the advantages that, adjust the amount of compression of knurled wheel 3 and seal groove inner wall surface and control clamping device 1 drive roller shaft 2 and seal groove relative motion by Digit Control Machine Tool, knurled wheel 3 is done passive revolution under roller shaft 2 effects, the gear of this knurled wheel 3 forms embossing in the seal groove inner wall surface simultaneously, thereby is implemented in annular knurl on the narrower seal groove inwall of width.
The utility model utilizes the machine tool numerical control system with Helix Interpolation when technology is operated, and adopts the circulation roll extrusion to avoid cutting interference.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
