Description
Technical Field
The invention relates to the technical field of machining, in particular to a clamping and limiting device for a square pulling groove of an adjustable wrench.
Background
In the production and processing process of pulling the square groove by the movable spanner, a corresponding limiting clamp is required to be added for ensuring the product quality. At present, the prior art generally adopts a simple rigid limiting clamp to ensure that the symmetrical central plane of a spanner body is horizontally laid and simultaneously the safe feeding and retracting of a broach is ensured; however, in the process of square groove drawing, the conventional limiting clamp can easily draw and deform the large hole of the wrench tongue combination, which affects subsequent wrench tongue assembly and reduces the processing quality of the wrench.
Disclosure of Invention
Aiming at the problems, the invention provides a clamping and limiting device for pulling a square groove by a movable wrench, which solves the problem of deformation of a large eye during pulling the square groove, improves the product quality of the movable wrench, improves the assembly efficiency of a wrench tongue, and greatly reduces the production cost.
In order to achieve the technical purpose and achieve the technical effects, the invention is realized by the following technical scheme:
a clamping limiting device for a movable pull square groove comprises a fixed base plate, a clamp heightening block, a pull body limiting clamp, a dovetail guide rail, a dovetail slide block, a cutter withdrawing press block, a large eye pin die, an oil cylinder floating push block, an oil cylinder and an oil cylinder fixing block.
Further, a clamp heightening block is arranged on the right side of the fixed bottom plate, a dovetail guide rail is arranged in the middle of the fixed bottom plate, and an oil cylinder fixed block is arranged on the left side of the fixed bottom plate; a spanner body limiting clamp is arranged on the clamp block, a dovetail slide block capable of moving left and right is arranged on the dovetail guide rail, and an oil cylinder is arranged on the oil cylinder fixing block. The tool retracting press block is fixed on the left side of the dovetail slide block, and the large-hole pin die is fixed on the upper side of the dovetail slide block. The oil cylinder floating push block is fixed at the front end of the oil cylinder rod. The oil cylinder floating push block is connected with the dovetail slide block through a trapezoidal groove and has certain floating.
Furthermore, the oil cylinder can push the dovetail slide block rightwards through the oil cylinder floating push block, so that the left tool retracting press block and the upper large-hole pin die move.
The beneficial effects are as follows:
1. the invention has compact design structure, and prevents the broaching tool from square drawing groove to deform the big hole by inserting the big hole pin die into the big hole of the spanner body, thereby improving the precision of the big hole and further improving the production efficiency and the product quality.

Detailed Description
The technical solutions of the present invention are further explained below with reference to the drawings and examples, but the following contents are not intended to limit the scope of the present invention.
The embodiment provides a clamping and limiting device for a movable spanner pulling square groove, which comprises a fixed base plate 102, a clamp heightening block 103, a spanner body limiting clamp 104, a dovetail guide rail 105, a dovetail slide block 106, a tool retracting press block 107, a large-hole pin die 108, an oil cylinder floating push block 109, an oil cylinder 110 and an oil cylinder fixing block 111, as shown in fig. 1.
Wherein the right side of the fixed bottom plate 102 is provided with a clamp heightening block 103, the middle part is provided with a dovetail guide rail 105, and the left side is provided with an oil cylinder fixed block 111; a spanner body limiting clamp 104 is arranged on the clamp block 103, a dovetail slide block 106 capable of moving left and right is arranged on the dovetail guide rail 105, and an oil cylinder 110 is arranged on the oil cylinder fixing block 111. The tool retracting pressing block 107 is fixed on the left side of the dovetail sliding block 106, and the large-eye pin die 108 is fixed on the upper side of the dovetail sliding block 106. The oil cylinder floating push block 111 is fixed at the front end of the oil cylinder rod. The oil cylinder floating push block 111 is connected with the dovetail slide block 106 through a trapezoid groove and has certain floating. The oil cylinder 110 can push the dovetail slide block 106 rightwards through the oil cylinder floating push block 109, so that the left tool retracting press block 107 and the upper large-hole pin die 108 move.
In the embodiment, the pushing and withdrawing of the oil cylinder 110 are controlled by a program, so that the sequential actions of the broach and the large-hole pin die are ensured to be not interfered with each other.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications or variations may be made without inventive faculty based on the technical solutions of the present invention.
