Abstract
The utility model discloses an inner thread standoff detecting device for a large-diameter casing joint. The detecting device comprises a bracket and a platform, wherein the backet is in an inverted L shape and is fixed on one end of the platform, the upper end of the bracket is provided with a sliding block, one side of the sliding block is connected with a first screw rod, and the first screw rod pushes the sliding block to move transversely along the bracket; the lower end of the sliding block is provided with a balancer, and the lower end of the balancer is provided with a thread gauge; the other end of the platform is provided with a second screw rod, the second screw rod is slidingly matched and connected with a screw nut, and the screw nut is fixed on the platform; the top end of the second screw rod is provided with a pressing plate, and the second screw rod pushes the pressing plate to move transversely along the platform; and one end of the platform, on which the bracket is fixed, is provided with a workpiece clamping device. The inner thread standoff detecting device has the advantages of simple structure and low manufacturing cost, and can reduce the labor intensity of the detection personnels; and the clamping plate and the end plate can effectively fix the workpiece, so as to prevent the workpiece from sliding during the measurement process, and the sliding block can adjust the position of the thread gauge conveniently, so as to bring convenience for measurement.
Description
Technical field
The utility model relates to the tight device for detecting distance of a kind of casing coupling internal thread.
Background technology
Domestic and international most of sleeve pipe processing factory all adopts the mode of manually tightening to carry out internal thread and detects, and detection efficiency is lower.When carrying out heavy caliber casing coupling internal thread closely apart from detection, need manpower external thread gauge to be removed and it is tightened on the box cupling screw thread at present.Because the gauge weight of the tight distance of heavy caliber casing threads to be measured is big, in testing process, need screwing force also big, therefore in tightening to the process of box cupling screw thread, external thread gauge produces relative slip because screwing force is big with workpiece, need a people to control workpiece one people and tighten, detection efficiency is low.
The utility model content
The technical problems to be solved in the utility model provides the tight device for detecting distance of a kind of heavy caliber casing coupling internal thread, and simple in structure, cost of manufacture is low, can reduce testing staff's labour intensity; Clamp device and end plate be fixation workpiece effectively, avoids the slip of workpiece in measuring process, and the position that slide block can be regulated external thread gauge easily is convenient for measuring.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the tight device for detecting distance of a kind of heavy caliber casing coupling internal thread comprises support and platform; Being shaped as of support is L shaped, and support is fixed in an end of platform, and the support upper end is provided with slide block, and a side of slide block links to each other with first leading screw, and it is laterally mobile along support that first leading screw promotes slide block; The slide block lower end is provided with evener, and the evener lower end is provided with external thread gauge;
The other end of platform is provided with second leading screw, second leading screw and screw sliding connection, and screw is fixed on the platform; The top of second leading screw is provided with pressing plate, and it is laterally mobile along platform that second leading screw promotes pressing plate;
The fixing standoff end of platform is provided with Workpiece clamping device.
Clamp device is V-arrangement towards a side of pressing plate, and corresponding with pressing plate.
The pressing plate outside is provided with end plate.
Evener links to each other with slide block by hook.
External thread gauge links to each other with evener by hook, and can along the circumferential direction rotate.
Support is made by channel-section steel.
The beneficial effect that adopts technique scheme to produce is: the utility model pick-up unit, and simple in structure, cost of manufacture is low, can reduce testing staff's labour intensity; Clamp device and end plate be fixation workpiece effectively, avoids the slip of workpiece in measuring process, and the position that slide block can be regulated external thread gauge easily is convenient for measuring.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Workpiece clamping device structural representation on the platform;
1 is support, and 2 is platform, and 3 is slide block, and 4 is first leading screw, and 5 is evener, and 6 is external thread gauge, and 7 is second leading screw, and 8 is screw, and 9 is pressing plate, and 10 is Workpiece clamping device, and 11 is end plate.
Embodiment
The tight device for detecting distance of heavy caliber casing coupling internal thread comprises support 1 and platform 2; Being shaped as of support 1 is L shaped, and described support 1 is fixed in an end of platform 2, and support 1 upper end is provided with slide block 3, and a side of slide block 3 links to each other with first leading screw 4, and it is laterally mobile along support 1 that first leading screw 4 promotes slide block 3; Slide block 3 lower ends are provided with evener 5, and evener 5 lower ends are provided with external thread gauge 6;
The other end of platform 2 is provided with second leading screw, 7, the second leading screws 7 and screw 8 sliding connections, screw 8 by bolt and spacers on platform 2; It is laterally mobile along platform 2 that the top of second leading screw 7 is provided with pressing plate 9, the second leading screws 7 promotion pressing plates 9;
Evener 5 links to each other with slide block 3 by hook.
When the utility model uses external thread gauge is suspended on the evener, evener is fixed on the slide block, before using according to the pulling force of the weight adjustment device of gauge, make external thread gauge be in equilibrium state substantially, again workpiece is put on the verifying bench, V-arrangement face and end plate by clamp device clamp workpiece, and the sliding position according to location of workpiece adjustment slide block to be checked can carry out closely apart from detecting at last.
Because workpiece for measurement is effectively clamping work pieces of cylindric employing V-arrangement face, reaches an equilibrium of forces by the pulling force of evener and the weight of the external thread gauge that is draped, thereby reduce testing staff's labour intensity.
