Abstract
The utility model relates to a large-torque cross universal joint device used for fixing a boring cutter power head and a boring bar and belongs to the field of boring tool equipment. The large-torque cross universal joint device comprises a first universal joint and a second universal joint, wherein the end portion of the first universal joint and the end portion of the second universal joint are arranged oppositely. The mutually butt joint end portions of the first universal joint and the second universal joint are provided with mutually matched cross key-groove structures. The periphery of the connecting end of the first universal joint and the periphery of the connecting end of the second universal joint are respectively provided with an annular clamping groove. The peripheries of the annular clamping grooves are provided with a first clamping ring and a second clamping ring respectively, wherein the first clamping ring and the second clamping ring are axially subdivided. The first clamping ring and the second clamping ring are fixedly connected through a plurality of bolts and nuts, wherein the bolts and the nuts are evenly distributed in the circumferential direction. According to the structure, the whole strength and stiffness of a boring rod power head connecting device are obviously improved, the service life of the universal joints is prolonged, the feeding amount and the feeding speed of boring cutters in the process of hole boring are increased and the machining efficiency of bored holes is improved.
Description
Technical field
The utility model relates to the boring technological equipment apparatus field, and is particularly a kind of for fixedly boring cutter unit head and boring bar high pulling torque cross universal regulating device.
Background technique
In bore hole processing, particularly in the string axle boring bore hole process, the universal joint attachment hole that adopts transition disc between special plane unit head and the boring bar and cooperate with it is connected, and rotates load and axial feed load with four clamping bolts and the transmission of universal joint attachment hole, and its advantage is that translation-angle is big, shortcoming is that intensity is lower, the universal joint fracture phenomena often occurs in the bore hole processing, it is more frequent to change universal joint, and the universal joint endoporus also needs to join car with transition disc during replacing, increase labor intensity, improved cost of production.Because the join strength of universal joint is lower, bore hole adds can only adopt less bite man-hour in addition, and feed speed is also slower, influences the efficient of bore hole processing greatly.
The model utility content
The utility model has problems at prior art, and a kind of join strength height is provided, and does not need the high pulling torque cross universal regulating device of frequently changing universal joint and can improving the bore hole work efficiency.
Order of the present utility model is to realize like this, a kind of high pulling torque cross universal regulating device, comprise the mutual opposed universal joint one in end and universal joint two, described universal joint one and universal joint two are provided with the cross keyway arrangements that cooperatively interacts in the end of butt joint mutually, and the periphery of universal joint one and universal joint two connecting ends is respectively equipped with annular slot, the periphery of described annular slot is corresponding snap ring one and the snap ring two that is provided with axial subdivision respectively, and the mutual vertical card of axial subdivision line of described snap ring one and snap ring two is contained in the annular slot periphery and fixedlys connected by circumferential uniform some bolt and nuts.
High pulling torque cross universal regulating device of the present utility model, the cross keyway that employing cooperatively interacts transmits the rotation load of boring processing, snap ring and annular slot transmit axial feed load, bearing strength is much larger than the intensity of bolt and hole transmitted load, therefore structure of the present utility model has obviously improved boring bar unit head connection set integral intensity and rigidity, prolongs the working life of universal joint, and can increase the amount of feed and the feed speed of boring cutter in the bore hole processing, improve the efficient of bore hole processing.
Be connected trueness error to improve the integral rigidity of universal joint for ease of what regulate unit head and boring bar, the monolateral matching gap of described cross keyway is 1mm.
Description of drawings
Fig. 1 is high pulling torque universal joint cross apparatus structure schematic representation of the present utility model.
Fig. 2 is that Fig. 1 is at the partial enlarged drawing at I place.
Wherein, 1 universal joint one; 2 snap rings one; 3 snap rings two; 4 bolt and nuts; 5 universal joints two; 6 cross keyways.
Embodiment
Be high pulling torque cross universal regulating device of the present utility model as depicted in figs. 1 and 2, comprise the mutual opposed universal joint 1 in end and universal joint 25, universal joint 1 and universal joint 25 are provided with cross keyway 6 structures that cooperatively interact in the end of butt joint mutually, and the periphery of universal joint 1 and universal joint 25 connecting ends is respectively equipped with annular slot, the periphery of annular slot is corresponding snap ring 1 and the snap ring 23 that is provided with axial subdivision respectively, and the mutual vertical card of axial subdivision line of snap ring 1 and snap ring 23 is contained in the annular slot periphery and fixedlys connected by circumferential uniform some bolt and nuts; For ease of regulating, the monolateral matching gap of cross keyway 6 is 1mm.
High pulling torque cross universal regulating device of the present utility model, the cross keyway 6 that employing cooperatively interacts transmits the rotation load of boring processing, snap ring and annular slot transmit axial feed load, bearing strength is much larger than the intensity of bolt and hole transmitted load, and the gap adjustment unit head of cross keyway 6 and boring bar centration error are to improve the coupling stiffness of universal joint.Therefore structure of the present utility model has obviously improved boring bar unit head connection set integral intensity and rigidity, prolongs the working life of universal joint, and can increase the amount of feed and the feed speed of boring cutter in the bore hole processing, improves the efficient of bore hole processing.
Be connected trueness error to improve the integral rigidity of universal joint for ease of what regulate unit head and boring bar, described.
The utility model is not limited to above-described embodiment; every on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in the scope of the utility model protection.
