Description
Technical field
The invention belongs to steel pipe process equipment field, be specifically related to a kind of one end of steel pipe can clamping, and steel pipe do not caused to the fixture of damage.
Background technology
Include multiple processing step in the process of steel pipe, in order to make steel pipe in each process, precision is higher, needs to clamp steel pipe, needs the fixture using turning attachment one class needs to clamp from the outside of steel pipe it during clamping.Although steel pipe can tightly clamp by this type of fixture, once operator's overexertion, very easily make the outer surface of steel pipe deform, thus affect the quality of steel pipe.
Therefore, developing one can carry out held tight to steel pipe, does not cause the fixture of damage to be those skilled in the art institute urgent need to solve the problem again to steel pipe simultaneously.
Summary of the invention
For solving the problem, the invention discloses a kind of one end of steel pipe can clamping, and steel pipe not caused to the fixture of damage.
In order to achieve the above object, the invention provides following technical scheme:
A kind of pipe diameter fixture, comprises clamping apparatus disk and adjustable steel pipe internal diameter limits sheet; Clamping apparatus disk is discoid, and mills out mounting hole on its surface, and is welded with reinforcement; Clamping apparatus disk is divided equally by mounting hole, and slidably connects restriction sheet contiguous block in mounting hole; Restriction sheet contiguous block is fixed with screw rod and adjustable steel pipe internal diameter limits sheet; Screw rod is connected with adjusting rod; Adjusting rod is matched by screw thread with screw rod; It is arcuation that adjustable steel pipe internal diameter limits sheet; The quantity that adjustable steel pipe internal diameter limits sheet is identical with the quantity of mounting hole.
The invention provides a kind of pipe diameter fixture, limit sheet by clamping apparatus disk and adjustable steel pipe internal diameter and form.
Clamping apparatus disk in the present invention is discoid, mills out mounting hole on the surface by miller, and the upper reinforcement of welding; Slidably connect in mounting hole and limit sheet contiguous block; The side limiting sheet contiguous block is fixed with through limiting sheet in adjustable steel pipe, and opposite side is connected with adjusting rod by screw rod.
Clamping apparatus disk in use, is first resisted against one end of steel pipe by the present invention, and makes adjustable steel pipe internal diameter restriction sheet be positioned at the inside of steel pipe, and adjusting rod is positioned at the outside of steel pipe; After adjusting rod is unscrewed, restriction sheet contiguous block is driven to slide in mounting hole by adjusting rod, adjustable steel pipe internal diameter restriction sheet is made to be close to the inwall of steel pipe, again tighten adjusting rod, make adjusting rod and clamping apparatus disk close contact, make the top limiting sheet contiguous block near mounting hole, restriction sheet contiguous block is fixed, realizes the clamping to the internal diameter of steel pipe further.
As preferably, it is arcuation nylon sheet that pipe diameter limits sheet, and the radius of the place camber line of arcuation nylon sheet is all identical.
The present invention selects arcuation nylon sheet to limit sheet as pipe diameter, nylon sheet has certain mechanical strength, toughness is high, ageing-resistant performance good, service life is extended, when steel pipe inner wall is extruded, the fixation to steel pipe can not only be ensured, effectively can also prevent because firmly excessive simultaneously, cause steel pipe generation deformation; And the mechanical damping capacity of nylon sheet is good, added to the steel pipe be under clamp position man-hour, can ensure that steel pipe does not vibrate, or reduce Oscillation Amplitude to greatest extent, effectively ensure that precision steel pipe being added to man-hour.
As preferably, the quantity of mounting hole is 3-6; Reinforcement and adjusting rod are in the same side of clamping apparatus disk, and clamping apparatus disk is divided equally by reinforcement equally.
The quantity of mounting hole is chosen as 3-6 by the present invention; If the steel pipe less to internal diameter clamps, the fixture with 3 mounting holes can be selected, just have 3 adjustable steel pipe internal diameters to limit sheet accordingly and internal diameter is fixed, although the internal diameter of steel pipe is less, but the quantity that adjustable steel pipe internal diameter limits sheet is also less, can not influence each other.If the steel pipe larger to internal diameter clamps, then can select the fixture with 4-6 mounting hole, now 3 adjustable steel pipe internal diameters restriction sheets cannot meet the fixing needs of internal diameter compared with big steel pipe, therefore need more adjustable steel pipe internal diameter to limit sheet, are advisable for 4-6.
As preferably, limit between sheet contiguous block and adjusting rod and be also provided with pad.
The present invention is provided with pad between restriction sheet contiguous block and adjusting rod, and make the adjusting rod matched with screw rod when tightening, pad can play effective cushioning effect, prevents from firmly excessively causing stripped thread, makes to limit sheet contiguous block and cannot be fixed in mounting hole.
As preferably, the edge of mounting hole is also provided with graduation mark.
The present invention is provided with graduation mark at the edge of mounting hole, specifically be positioned at the edge of mounting hole near adjusting rod, so that when clamping the steel pipe of same size, directly by adjusting rod, adjustable steel pipe internal diameter can be limited sheet and sliding into corresponding graduation mark position, saving the time.
As preferably, adjusting rod is also connected with adjusting rod swingle.
The present invention is provided with adjusting rod swingle at the end of adjusting rod, adjusting rod can be driven to rotate by rotation adjusting lever swingle in use, time saving and energy saving.
The present invention is compared with existing steel pipe clamp, and beneficial effect is: (1) structure is simple, low cost of manufacture; (2) easy to use, increase work efficiency; (3) while not damaging steel pipe, good clamping effect.
