In order to ensure the center distance, the coaxiality and the parallelism between the double ear plates 3, a debugging card code is designed.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect that exists among the prior art, the utility model aims at providing a card sign indicating number with adjustable for press from both sides tight binaural board, adjust the size of opening a grade of binaural board, improve the assembly precision.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an adjustable clamp code comprises an adjusting mechanism and clamping mechanisms respectively connected to two end parts of the adjusting mechanism;
the clamping mechanisms comprise clamping blocks, clamping grooves are formed in the clamping blocks, bolt holes penetrating through the clamping grooves are formed in the front end portions of the clamping blocks, and jacking bolts are arranged in the bolt holes;
adjustment mechanism, including the internal thread pipe, the inside of internal thread pipe is equipped with a limit stop, through limit stop will the inside of internal thread pipe separates into two regulation holes, every all be furnished with the external screw thread pole in the regulation hole, the external screw thread pole corresponds and connects the rear end portion of fixture block.
The limit stop is positioned in the center of the inner part of the internal thread pipe.
And the adjusting inner hole is provided with a thread in a forward rotating direction, and the adjusting inner hole is provided with a thread in a reverse rotating direction.
The thread of one of the external thread rods is arranged in the positive rotating direction, and the thread of the other external thread rod is arranged in the negative rotating direction.
In foretell technical scheme, the utility model provides a card sign indicating number with adjustable, simple structure, the preparation of being convenient for, operation convenient to use can realize the quick clamping of drag link, prevents to produce the error when the assembly, also can satisfy the dimensional requirement such as opening the shelves of adjusting the binaural board, can open the shelves size according to the difference in the drawing and adjust the binaural board, improves the assembly precision.

Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.
Referring to fig. 3 to 5, the adjustable clamp of the present invention includes an adjusting mechanism and a clamping mechanism connected to two ends of the adjusting mechanism respectively.
Clamping mechanism, all include fixture block 4, offer on fixture block 4 and be used for blocking 3 marginal draw-in grooves 5 of binaural board, offer a bolt hole that transversely link up in draw-in groove 5 on the preceding tip of fixture block 4, at the downthehole tight bolt 6 that is furnished with in the bolt, go into corresponding draw-in groove 5 with 3 cards of binaural board, make clamping mechanism be used for pressing from both sides tight binaural board 3, can realize the quick clamping to pull rod 1, prevent the error that produces when the assembly, the tight bolt 6 that pushes up of screwing again compresses tightly the 3 components of binaural board, guarantee that it is not influenced when assembly and welding.
The adjusting mechanism comprises an internal thread pipe 7, a limit stop 8 is arranged at the center of the inside of the internal thread pipe 7, the inside of the internal thread pipe 7 is divided into two adjusting inner holes 9 through the limit stop 8, each adjusting inner hole 9 is internally provided with an external thread rod 10, and the external thread rods 10 correspond to the rear end parts of the connecting clamping blocks 4.
Of the two adjusting inner holes 9, the thread of one adjusting inner hole 9 is set to be in a forward rotating direction, and the thread of the other adjusting inner hole 9 is set to be in a reverse rotating direction.
Of the two corresponding externally threaded rods 10, the thread of one of the externally threaded rods 10 is set to the forward rotational direction, and the thread of the other externally threaded rod 10 is set to the reverse rotational direction.
When the opening size of the double-lug plate 3 is adjusted, synchronous stretching of the two external threaded rods 10 can be achieved only by rotating the internal threaded pipe 7, the size requirements of adjusting the opening size of the double-lug plate and the like can be met, the double-lug plate can be adjusted according to different opening sizes in a drawing, and the assembling precision is improved.
The utility model discloses the concrete implementation of card code is as follows:
1) selecting a workpiece (pull rod) to be assembled;
2) assembling the double-lug plate to the main structure according to the assembling requirement;
3) according to the opening H value of the double-lug plate in the figure 2, the card code 100 is adjusted in place and then is installed on the double-lug plate 3;
4) and finally, welding the double-lug plate 3 and the main structure to prevent welding deformation.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
