Description

Clamp for grinding end face of broad-spectrum cylindrical workpiece

Technical Field

The utility model relates to a frock in the processing of cylindricality work piece, especially a broad spectrum type cylindricality work piece anchor clamps for terminal surface grinding, specially adapted is to the correct grinding processing of cylindricality work piece external seal terminal surface.

Background

In a traditional end face grinding tool for a cylindrical workpiece (shown in figure 1), a clamping jaw directly clamps the excircle of the cylindrical workpiece, a chuck positions the excircle, then a sealing surface is positioned, and the outer sealing end face of the cylindrical workpiece is finely ground, as shown in figure 2. The clamping mode is suitable for production and processing of a single product, when the model is changed, the clamping outer circle diameters of most cylindrical workpieces are different, the clamping jaws need to be changed, and the clamping jaws are ground again according to the clamped outer diameters (the clamping jaws are high in manufacturing cost and long in manufacturing period, and grinding of the clamping jaws needs a long time, so that normal production and processing are affected). Therefore, when the models of products are frequently changed, the clamping mode is obviously not applicable.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art and provides a clamp for grinding the end face of a broad-spectrum cylindrical workpiece.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a broad spectrum type cylindricality anchor clamps for work piece end face grinding, includes the end face grinding jack catch and the grinding machine chuck of centre gripping cylindricality work piece, cylindricality work piece inner is connected with the grinding machine chuck through end face grinding cassette, the cover is equipped with rather than external diameter matched with commentaries on classics clamp cover on the cylindricality work piece excircle, it is tight that the cover is pressed from both sides by end face grinding jack catch to change the clamp cover, is equipped with on changeing the clamp cover and presss from both sides tight breach and deformation recess, presss from both sides tight breach and deformation recess and all follows the axial distribution that changes.

The clamping gap can clamp the excircle of the cylindrical workpiece when the rotating clamping sleeve is clamped by the three end face grinding clamping jaws, and the deformation groove enables the rotating clamping sleeve to have resilience.

Further, the number of the deformation grooves is two, and the two deformation grooves and the clamping notches are uniformly distributed along the circumferential direction. By the arrangement, the stress of the whole rotary clamping sleeve can be ensured to be uniform.

Further, the number of the end face grinding clamping jaws is three, and the three end face grinding clamping jaws are uniformly distributed on the end face of the grinding machine chuck. The three end face grinding clamping jaws perform self-centering clamping pressure on the rotary clamping sleeve.

The utility model has the advantages that: the utility model discloses compare prior art and add the commentaries on classics cover that presss from both sides, can satisfy the needs that cylindricality work piece model was changed frequently in the production and processing, only need to change the commentaries on classics of different specifications when changing different model cylindricality work pieces moreover and press from both sides the cover, and the period that the commentaries on classics of making different specifications pressed from both sides the cover is short, with low costs, this kind of clamp dress mode convenient and fast, need not consume the coping jack catch for a large amount of time, just also saved the expense of making the jack catch and the consumption quantity of emery wheel, the cylindricality work piece grinding process production.

Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 2, the clamp for grinding the end face of the broad-spectrum cylindrical workpiece comprises an end face grinding jaw 5 for clamping the cylindrical workpiece 3 and a grinding machine chuck 1, wherein the rear end of the cylindrical workpiece 3 is connected with the grinding machine chuck 1 through the end face grinding jaw 2, a rotary clamping sleeve 4 matched with the outer diameter of the cylindrical workpiece 3 is sleeved on the outer circle of the cylindrical workpiece 3, the rotary clamping sleeve 4 is clamped by the three end face grinding jaws 5, as shown in fig. 3, a clamping gap 4-1 and a deformation groove 4-2 are arranged on the rotary clamping sleeve 4, the clamping gap 4-1 and the deformation groove 4-2 are distributed along the axial direction of the rotary clamping sleeve 4, and the clamping gap 4-1 and the deformation groove 4-2 are uniformly distributed along the. The rotary clamping sleeve 4 with the structure can reliably and automatically clamp the excircle of the cylindrical workpiece 3 when being clamped by the end face grinding clamping jaw 5.

The diameter of the excircle of the cylindrical workpiece 3 in production is generally not more than 40mm, so the clamping of grinding processing is completed through the rotary clamping sleeve 4. The clamping mode can meet the requirement of frequently replacing the models of the cylindrical workpieces 3 in production and processing, and when products of different models are replaced, the specifications (inner diameter and length) of the rotary clamping sleeve 4 are only needed to be replaced, and the corresponding rotary clamping sleeve 4 is manufactured for the cylindrical workpieces 3 of different models. The clamping mode is convenient and fast to replace the rotating sleeve 4. Compared with the clamping jaws directly adopted, the clamping sleeve 4 has the advantages of low manufacturing cost and short manufacturing period (can meet the production requirement of emergency model replacement temporarily); compared with the traditional clamping mode, the clamping does not need to consume a large amount of time to polish the clamping jaws, so that the cost for manufacturing the clamping jaws and the consumption amount of grinding wheels are saved, and the cost for grinding and processing the cylindrical workpiece 3 is reduced to the maximum extent.
