Abstract
The utility model relates to a rotating and lifting device of the tooth claw and shaft neck of a roller bit welded by an electron beam, mainly comprising a rotary sleeve, a spline shaft, a guide sleeve, a clamping chuck, a base, a guide surface and a roller. The rotary sleeve has bores, and the roller is arranged at the lower part of the rotary sleeve. The spline shaft is connected with the internal spline bore of the rotary sleeve, and the lower part of the spline shaft is clamped by the clamping chuck. The guide sleeve is fixed on the base by bolts, and the guide surface at the upper end of the guide sleeve is spatial curved surface. The position change along the shaft direction of the curved surface is consistent to the position change of the welded surface. The device is matched with the electron-beam welder to realize the rotating and elevating of the tooth claw and the shaft neck to keep the distance between the electron-beam gun and the welded surface constant, which solves the complicated welding problem of different depths of weld of the tooth claw and the shaft neck.
Description
The utility model relates to a kind of rotating lifting gear that is used to weld rock bit tooth pawl and axle journal.
Now use rock bit, tooth pawl and axle journal are forged integral body, process by lathe again, cause processing difficulties owing to have unbalanced tooth pawl on the axle journal, and produce thermal deformation between the datum level of axle journal and tooth pawl when influencing machining accuracy and heat treatment, thereby influence the assembly precision of drill bit.
For overcoming the problem that exists in the above-mentioned processing, adopt that tooth pawl, axle journal forge respectively, processing and heat treatment, be welded into a whole then.Because the welding position of tooth pawl and axle journal is a space curve, the depth of weld is not of uniform size, and present electron-beam welder can only solve the depth of weld to be changed, and can not solve the face of weld change in location.
The purpose of this utility model is exactly the special equipment-rotating lifting gear that designs for addressing the above problem, this device cooperates with electron-beam welder, rotation of tooth pawl and axle journal and lifting when realizing welding make electron beam gun and face of weld distance constant, thereby realize the welding of tooth pawl and axle journal.
The utility model is achieved in that the utility model design one drives axle journal (1) and tooth pawl (2) rotation in order to solve above-mentioned task, and the while is along the device of axis (8) lifting.Rotating lifting gear mainly is made up of rotary sleeve, splined shaft, fairlead, chuck, support, spigot surface and roller.Rotary sleeve has endoporus on (10), rotary sleeve bottom outer rim is provided with roller (17), the internal splined hole of the top of splined shaft (11) and rotary sleeve (10) links, and fairlead (12) is fixed on the support (15) by bolt (13), and the upper end of fairlead (12) is spigot surface (16).
Fig. 1 is welded into the structural representation of integral body for tooth pawl and axle journal;
Fig. 2 is the rotating lifting gear structural representation.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is axle journal and the tooth pawl that forges heat treatment and processing separately.As shown in the figure: form by axle journal (1), tooth pawl (2), shoulder (3), assembling axle journal (4), hole (5), datum level (6), electron beam gun (7), parallel to the axis (8).
Fig. 2 is the utility model structural representation, and this device is made up of screw (9), rotary sleeve (10), splined shaft (11), fairlead (12), bolt (13), chuck (14), support (15), spigot surface (16) and roller (17).Rotary sleeve (10) bottom is provided with the top of cylindrical roller (17), splined shaft (11) and the internal spline of rotary sleeve (10) links, bottom chuck (14) clamping; Fairlead (12) is provided with through hole along axis direction, the aperture is greater than the maximum gauge of splined shaft (11), the spigot surface (16) of fairlead (12) upper end is a space curved surface, and curved surface is consistent with the space curve change in location vertically on soldered surface along the change in location of axis direction.Fairlead (12) bottom is evenly equipped with four screw holes, is fixed on the support (15) by bolt (13), and the workbench of fairlead and electron-beam welder is fixed together.The assembling axle journal (4) of axle journal (1) is packed into interference fits in the hole (5) of tooth pawl (2), axle journal (1) is packed in the upper hole of rotary sleeve (11) of wounded in the battle keyhole, fixing by screw (9), roller (17) contacts with the spigot surface (16) of fixed guide cover (12), spigot surface (16) is pressed the space curve design on the soldered surface of tooth pawl (2), the internal splined hole of the top of splined shaft (11) and rotary sleeve (10) links, bottom chuck (14) clamping.When chuck (14) drives spline (11) rotation, by splined shaft (11) driven rotary cover (10), axle journal (1), tooth pawl (2) rotation, and by spigot surface (16) rising or the decline of the roller (17) that is connected with rotary sleeve (10) along fixed guide cover (12), thereby make electron beam gun and face of weld keep a constant distance h, by the Synchronization Control of electron-beam welder, realize having the tooth pawl of different depth requirement and the welding of axle journal.
This apparatus structure is simply easy to use, with the axle journal and the tooth pawl of this device welding rock bit, can improve the accuracy of manufacture and the case hardness of axle journal, thus the life-span of improving bearing arrangement.
Claims (3)
1, a kind of rotating lifting gear that welds rock bit tooth pawl and axle journal, mainly form by rotary sleeve, splined shaft, fairlead, chuck, support, spigot surface and roller, it is characterized in that having endoporus on the rotary sleeve (10), rotary sleeve (10) bottom outer rim is provided with roller (17); Splined shaft (11) links with the internal splined hole of rotary sleeve (10), bottom chuck (14) clamping; Fairlead (12) is fixed on the support (15) by bolt (13), and the upper surface of fairlead (12) is spigot surface (16).
