Abstract
The invention provides a steel pipe inner diameter clamp which comprises a clamp disc and steel-pipe-inner-diameter-adjustable limiting pieces. The clamp disc is in a disc shape. Kidney-shaped holes are formed in the surface of the clamp disc in a milling mode. The clamp disc is welded with a reinforcing rib. The kidney-shaped holes evenly divide the clamp disc. Limiting piece connecting blocks are connected into the kidney-shaped holes in a sliding mode. The limiting piece connecting blocks are fixedly provided with screw rods and the steel-pipe-inner-diameter-adjustable limiting pieces. The screw rods are connected with adjusting rods which are matched with the screw rods through threads. The steel-pipe-inner-diameter-adjustable limiting pieces are in an arc shape. The number of the steel-pipe-inner-diameter-adjustable limiting pieces and the number of the kidney-shaped holes are equal. The steel pipe inner diameter clamp is simple in structure, low in manufacturing cost and convenient to use, working efficiency is improved, and clamping effect is good under the situation that a steel pipe is not damaged.
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 the fixture of damage.
Background technology
In the process of steel pipe, include a plurality of processing steps, in order to make steel pipe in each process, precision is higher, need to clamp steel pipe, during clamping, need to use turning attachment one class need to be from the outside of steel pipe the fixture to its clamping.Although this type of fixture can tightly clamp steel pipe, once operator's overexertion very easily makes the outer surface of steel pipe deform, thereby affect the quality of steel pipe.
Therefore, develop a kind of can closely clamping steel pipe, steel pipe is not caused to the fixture of damage is again those skilled in the art institute urgent need to solve the problem simultaneously.
Summary of the invention
For addressing the above problem, the invention discloses a kind of one end of steel pipe can clamping, and steel pipe is not caused the fixture of damage.
In order to achieve the above object, the invention provides following technical scheme:
A pipe diameter fixture, comprises that clamping apparatus disk and adjustable steel bore limit sheet; Clamping apparatus disk is discoid, and mills out mounting hole on its surface, and is welded with reinforcement; Mounting hole is divided equally clamping apparatus disk, and in mounting hole, slidably connects restriction sheet contiguous block; Limit sheet contiguous block and be fixed with screw rod and adjustable steel bore restriction sheet; Screw rod is connected with adjusting rod; Adjusting rod matches by screw thread with screw rod; Adjustable steel bore limits sheet and is arcuation; It is identical with the quantity of mounting hole that adjustable steel bore limits the quantity of sheet.
The invention provides a kind of pipe diameter fixture, by clamping apparatus disk and adjustable steel bore, limit sheet and form.
Clamping apparatus disk in the present invention is discoid, on surface, by miller, mills out mounting hole, and the upper reinforcement of welding; In mounting hole, slidably connect and limit sheet contiguous block; It is interior through limiting sheet that one side of restriction sheet contiguous block is fixed with adjustable steel pipe, and opposite side is connected with adjusting rod by screw rod.
The present invention in use, is first resisted against clamping apparatus disk one end of steel pipe, and makes adjustable steel bore limit the inside that sheet is positioned at steel pipe, and adjusting rod is positioned at the outside of steel pipe; After adjusting rod is unscrewed, by adjusting rod, drive restriction sheet contiguous block to slide in mounting hole, make adjustable steel bore limit the inwall that sheet is close to steel pipe, again tighten adjusting rod, make adjusting rod and clamping apparatus disk close contact, make the top that limits sheet contiguous block near mounting hole, to limiting sheet contiguous block, be fixed, further realize the clamping to the internal diameter of steel pipe.
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, extended service life, when steel pipe inner wall is pushed, not only can guarantee the fixation to steel pipe, can also effectively prevent because firmly excessive simultaneously, cause steel pipe generation deformation; And the mechanical damping capacity of nylon sheet is good, adds man-hour at the steel pipe under clamp position, can guarantee that steel pipe does not vibrate, or reduce Oscillation Amplitude to greatest extent, effectively guaranteed steel pipe to add the precision in man-hour.
As preferably, the quantity of mounting hole is 3-6; Reinforcement and adjusting rod the same side in clamping apparatus disk, and reinforcement is divided equally clamping apparatus disk equally.
The present invention is chosen as 3-6 by the quantity of mounting hole; If the steel pipe less to internal diameter clamps, can select the fixture with 3 mounting holes, just have accordingly 3 adjustable steel bores to limit sheet internal diameter is fixed, although the internal diameter of steel pipe is less, it is also less that but adjustable steel bore limits the quantity of sheet, can not influence each other.If the steel pipe larger to internal diameter clamps, can select the fixture with 4-6 mounting hole, now 3 adjustable steel bores restriction sheets cannot meet internal diameter compared with the fixedly needs of big steel pipe, therefore need more adjustable steel bore 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, makes the adjusting rod matching with screw rod when tightening, and pad can play effective cushioning effect, the excessive stripped thread that causes that prevents from exerting oneself, and making to limit sheet contiguous block 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 mounting hole near the edge of adjusting rod, so that when the steel pipe of same size is clamped, can directly by adjusting rod, adjustable steel bore be limited to sheet and slide into corresponding graduation mark position, saved 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, can drive adjusting rod to rotate by rotation adjusting rod swingle in use, time saving and energy saving.
The present invention compares with existing steel pipe clamp, and beneficial effect is: (1) is simple in structure, low cost of manufacture; (2) easy to use, increase work efficiency; (3) when not damaging steel pipe, good clamping effect.
