Abstract
The utility model relates to a down nozzle assembling and inspecting tool for steelmaking casting. The technical scheme is that the tool comprises a clamp (2) and a handle (4), wherein the handle is arranged at one side of the clamp; a cylindrical section (5), a transition angle (6), a circular table section (7), a straight-line section (8) and a tolerance zone (3) are arranged at the other side of the clamp; one end of the cylindrical section is vertically connected with the straight-line section and the tolerance zone (3) is arranged between the cylindrical section and the straight-line section; and the other end of the cylindrical section is connected with the circular table section through the transition angle, and the circular table section is connected with the clamp through the transition angle. The tool has the beneficial effects of simple structure, convenience for operation and low cost; and meanwhile, the tool can rapidly and accurately detect whether the size of the down nozzle is qualified or not, so that the product quality is guaranteed and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of steel-making and waters steel the usefulness mouth of a river assembling and the instruments of inspection down, particularly descends the instruments of inspection of mouth of a river critical size.
Background technology
Slide gate nozzle is the critical component that steel is watered in steel-making, plays the effect of control molten steel flow, and the following mouth of a river is one of ladle canal; If dimensional problem occurs, can cause badly bleeding, scurry the steel accident; Both caused economic loss, possibly cause the infringement of personal equipment again, so to mouth of a river size Control is particularly important down.The following mouth of a river is assembled by fire resistive material and box hat; Be installed in the lower skateboard bottom, screw, so the cylinder that the following mouth of a river cooperates with rotation set and the height dimension of round platform are critical sizes through mechanism's rotation set and slide plate; It also is the emphasis of controlling in the production run; If this oversize meeting causes the mouth of a river not installed,, can make between the slide plate and the following mouth of a river to produce the slit and cause bleed-out if this is undersized.When box hat and adobe are assembled in the production run, use this size of kind of calliper control not only time-consuming but also require great effort, influence work efficiency.And this size is made up of a cylinder and round platform, and junction all has knuckle, uses the kind of calliper error big.
The utility model content
The utility model purpose provides a kind of mouth of a river instruments of inspection down, directly is stuck in down on the mouth of a river or the finished product, judges whether size is qualified, solves the problems referred to above that exist in the background technology.
The technical scheme of the utility model is: the following mouth of a river instruments of inspection comprises jig, handle; Jig one side is provided with handle; Opposite side is provided with cylindrical section, transition angle, round platform section, straight-line segment, tolerance range, and cylindrical section one end is connected with straight-line segment is vertical, between be provided with tolerance range; The other end is connected with the round platform section through the transition angle, and the round platform section is connected with jig through the transition angle.
During use; Hand-held handle; Be close to down the cylindrical section and the round platform section at the mouth of a river; To descend transition angle, the mouth of a river and this to test novel transition angle and be adjacent to, and can whether have the slit to judge whether the adobe profile is qualified between novel, judge through the position of observing down the corresponding tolerance range of mouth of a river end face whether following mouth of a river size is qualified in addition through observing down the mouth of a river and this.
The beneficial effect of the utility model is: simple in structure, easy to operate, with low cost, simultaneously, can accurate detection go out whether mouth of a river size is qualified down, and guarantee product quality, enhance productivity.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model user mode synoptic diagram;
Among the figure: 1. descend the mouth of a river, 2. jig, 3. tolerance range, 4. handle, 5. cylindrical section, 6. transition angle, 7. round platform section, 8. straight-line segment, 9, following mouth of a river end face.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
With reference to accompanying drawing 1, the following mouth of a river instruments of inspection is formed by the cutting of 3mm steel plate line; Comprise jig 2, handle 4, jig one side is provided with handle, and the handle width is 30mm; Be convenient to hand, opposite side is provided with cylindrical section 5, transition angle 6, round platform section 7, straight-line segment 8, tolerance range 3, and cylindrical section one end is connected with straight-line segment is vertical; Between be provided with tolerance range, the other end is connected with the round platform section through the transition angle, the round platform section is connected with jig through the transition angle.
With reference to accompanying drawing 2, during use, hand-held handle; Be close to down the cylindrical section and the round platform section at the mouth of a river; To descend transition angle, the mouth of a river and this to test novel transition angle and be adjacent to, and can whether have the slit to judge whether the adobe profile is qualified between novel, judge through the position of observing down mouth of a river end face 9 corresponding tolerance ranges whether time mouth of a river size is qualified in addition through observing down the mouth of a river and this; If the upper edge of end face out-of-size band; Explain that size reaches the standard grade greater than requiring,, explain that then size rolls off the production line less than requiring if be lower than the tolerance range lower edge.When mouth of a river shell is with the assembling of the following mouth of a river down, can adopt this instrument need to judge whether the adjustment assembling position.Also can adopt this instrument to judge whether size is qualified during product inspection.
Claims (1)
1. following mouth of a river instruments of inspection; It is characterized in that comprising jig (2), handle (4), jig one side is provided with handle, and opposite side is provided with cylindrical section (5), transition angle (6), round platform section (7), straight-line segment (8), tolerance range (3); Cylindrical section one end is connected with straight-line segment is vertical; Between be provided with tolerance range (3), the other end is connected with the round platform section through the transition angle, the round platform section is connected with jig through the transition angle.
