Special single-moment-arm and double-working-station clamp for machining

[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0012] like figure 1 As shown, a single-arm double-station fixture dedicated to mechanical processing includes: a support plate 1, a left vertical plate 2, a right vertical plate 3, a lever force arm 4, an upper movable pin shaft 5, and a left trapezoidal threaded hole 6 , right trapezoidal threaded hole 7, left screw rod 8, right screw rod 9, bolt 10, movable clamping plate 11, workpiece 12, fixed clamping plate 13, ball head 14, triangular rib plate 15, left base 16, right base 17, The left vertical plate 2 is welded on the left side of the support plate 1 through the triangular rib plate 15, the right vertical plate 3 is welded on the right side of the support plate 1 through the triangular rib plate 15, and the lever arm 4 is passed through the upper movable pin The shaft 5 is installed in the center of the support plate 1, the left trapezoidal threaded hole 6 is processed at the bottom of the left vertical plate 2, the right trapezoidal threaded hole 7 is processed at the bottom of the right vertical plate 3, and the left screw rod 8 is installed in the left trapezoidal threaded hole 6 Inside, the right screw rod 9 is installed in the right trapezoidal threaded hole 7, the movable clamping plate 11 is installed on the top of the lever arm 4 through the bolt 10, and the fixed clamping plate 13 is welded on the right side of the left vertical plate 2 On the wall and on the left side wall of right riser 3.

[0013] Specifically, the ball head 14 is welded to the right end of the left screw 8 and the left end of the right screw 9, the left base 16 is welded to the bottom of the left vertical plate 2, and the right base 17 is welded to the bottom of the right vertical plate 3 , the workpiece 12 is clamped between the fixed clamping plate 13 and the movable clamping plate 11 .

[0014] In the technical solution of the present invention, the lever force arm is installed in the center of the support plate through the upper movable pin shaft, the left screw rod is installed in the left trapezoidal threaded hole, the right screw rod is installed in the right trapezoidal threaded hole, and the movable clamping plate passes through the bolt The design of the top installed on the lever force arm uses the left screw rod and the right screw rod to apply force to the lever force arm to realize the clamping and fixing of the workpiece by the movable clamping plate and the fixed clamping plate.

[0015] The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have Variations and improvements are possible, which fall within the scope of the claimed invention. The protection scope of the present invention is defined by the appended claims and their equivalents.
