Description
Technical field
The utility model relates to a kind of Workpiece machining apparatus, especially a kind of novel workpiece clamping mechanism for machining.
Background technology
At present, widely used hand clamp mechanism in welding procedure production field, because existing hand clamp mechanism reasonable in design is poor, interlock effect between each parts is undesirable, cause its weldment handling difficulty, loaded down with trivial details in production and application, be unfavorable for the lifting of operating efficiency, the clamping force providing is also inadequate, be unfavorable for workpiece processing, therefore need to improve.
Summary of the invention
The purpose of this utility model be the deficiency in order to solve above-mentioned technology and design a kind ofly clamp the effective novel workpiece clamping mechanism for machining.
The novel workpiece clamping mechanism for machining that the utility model is designed, comprises base, and base top is provided with a hinged seat, is hinged with pressure arm on hinged seat, and the pin joint of described pressure arm and hinged seat is positioned at pressure arm front portion; Described base has the passage of a lateral opening, in described passage, be provided with height adjustment plate, described height adjustment plate is provided with the wedge that cylinder and cylinder are in transmission connection, described cylinder is fixedly connected with height adjustment plate, wedge is removably set on height adjustment plate, in described base, be provided with an expansion link, described expansion link bottom surface is the inclined-plane matching with wedge, and expansion link top is rounded nose; Described pressure arm tail end has an arc inner concave, and described arc inner concave is positioned at described rounded nose top; Described base bottom is provided with leg, and on base, the position of height adjustment plate below is provided with height adjustment bolt.
The novel workpiece clamping mechanism for machining that the utility model is designed, cylinder can drive wedge to move left and right, because wedge matches with the inclined-plane of expansion link bottom surface, can be by upwards jack-up of expansion link when wedge moves to left, expansion link is by pressure arm tail end jack-up, pressure arm front end just presses down can workpiece pressing, adopts air cylinder driven operating efficiency higher, more stable when operation; The pin joint of pressure arm and hinged seat is positioned at pressure arm front portion, and the aft section of pressure arm is long like this, and according to lever principle, the less support force suffered at pressure arm afterbody can be converted into the thrust that front end is larger, therefore processing work better.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment 1 for the novel workpiece clamping mechanism of machining;
In figure: base 1, hinged seat 2, pressure arm 3, passage 4, height adjustment plate 5, cylinder 6, wedge 7, inclined-plane 71, rounded nose 72, expansion link 8, arc inner concave 9, leg 10, height adjustment bolt 11.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, the described novel workpiece clamping mechanism for machining of the present embodiment, comprises base 1, and base 1 top is provided with a hinged seat 2, is hinged with pressure arm 3 on hinged seat 2, and described pressure arm 3 is positioned at pressure arm 3 front portions with the pin joint of hinged seat 2, described base 1 has the passage 4 of a lateral opening, in described passage 4, be provided with height adjustment plate 5, described height adjustment plate 5 is provided with the wedge 7 that cylinder 6 and cylinder 6 are in transmission connection, so-called being in transmission connection is that wedge 7 is fixedly connected with the piston rod front end of cylinder 6, when cylinder 6 moves, piston rod is scalable, thereby drive wedge 7 to move left and right, described cylinder 6 is fixedly connected with height adjustment plate 5, wedge 7 is removably set on height adjustment plate 5, in described base 1, be provided with an expansion link 8, described expansion link 8 bottom surfaces are the inclined-plane 71 matching with wedge 7, expansion link 8 tops are rounded nose 72, described pressure arm 3 tail ends have an arc inner concave 9, and described arc inner concave 9 is positioned at described rounded nose 72 tops, described base 1 bottom is provided with leg 10, and on base 1, the position of height adjustment plate 5 belows is provided with height adjustment bolt 11, and height adjustment bolt 11 is spaced two.
Implement in you at this, pressure arm 3 is positioned at pressure arm 3 front end 1/4th places with the pin joint of hinged seat 2, certainly can also select other positions according to actual conditions, but ensure that pressure arm 3 back parts are longer than previous section, larger clamping force can not only be provided like this, in the time that cylinder orders about wedge 7 and exits to the right, pressure arm 3 afterbodys are because the effect of gravity can be fallen, be more convenient for like this front workpiece take out with put into, on the other hand, because having a tile height, this novel workpiece clamping mechanism for machining adjusts plate 5, height adjustment plate 5 regulates its upper-lower position by height adjustment bolt 11, the variation of height adjustment plate 5 height is finally married again on expansion link 8, the extreme position of pressure arm 3 tail end perks can be changed, the pinch zones height that pressure arm 3 front ends form has also changed, so not only can finely tune clamping force, and can regulate accordingly according to the difference of thickness of workpiece.Pressure arm 3 tail ends have an arc inner concave 9, and arc inner concave 9 matches with rounded nose 72, and can guarantee can have one to contact preferably with rounded nose 72 in the up and down process of pressure arm 3 afterbodys all the time.
The described novel workpiece clamping mechanism for machining of the present embodiment, clamps better effects if, more stable when operation, more convenient when operation.
Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
