Description
Technical field:
[0001] The utility model belongs to the field of mechanical processing tools, in particular to a clamping device for workpiece processing. Background technology:
[0002] V-shaped iron is often used in the process of mechanical processing. It is mainly used as a tool to support cylindrical workpieces such as shafts, pipes, sleeves, etc. The V-shaped iron can make the axis of the workpiece parallel to the working surface, so as to accurately align and mark the workpiece. In the practical use of V-shaped iron, the cylindrical workpiece can be supported by placing it on the V-shaped groove. However, due to many factors such as external forces on site, the cylindrical workpiece placed on the V-shaped groove is prone to displacement or rotation, resulting in errors in precise alignment and errors in marking operations, affecting the overall efficiency of workpiece processing. Utility model content:
[0003] The purpose of the utility model is to provide a clamping device for workpiece processing, and overcome the shortcomings of the above-mentioned prior art, which effectively solves the existing problems generated when processing cylindrical workpieces.

[0005] Furthermore, limit sliding rods are vertically arranged on both sides of the screw rod, a round hole is opened on the crossbeam of the frame, the limit sliding rod slides in the round hole, and the bottom end of the limit sliding rod is fixedly connected to the top wall of the cross plate.
[0006] Furthermore, a limiting cap is installed on the top end of the limiting sliding rod.
[0007] Furthermore, the bottom pressing surface of the rubber pressing block is in a semi-arc shape.
[0008] Furthermore, a hand wheel is installed on the top end of the screw.
[0009] Furthermore, slide blocks are installed at the two supporting bottom ends of the frame, and concave slide grooves are opened on the two side walls of the V-shaped iron in the extension direction, and the slide blocks slide in the concave slide grooves.
[0010] Furthermore, second screw holes are horizontally opened on the two vertical beams of the frame, and top screws are screwed into the second screw holes.
[0011] The beneficial effects of the utility model are as follows: the workpiece can be clamped on the V-shaped groove of the V-shaped iron by the rubber pressing block, thereby preventing the workpiece from being randomly displaced or rotated due to external force, ensuring accurate alignment or marking operation of the workpiece, and improving the overall processing efficiency.

Specific implementation method:
[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:
[0016] like Figure 1 to Figure 2 As shown, a clamping device for workpiece processing comprises a V-shaped iron 1, a frame 2 is arranged above the V-shaped iron 1, a first screw hole is vertically opened on the cross beam of the frame 2, a screw rod 3 is screwed in the first screw hole, a cross plate 4 is rotatably connected to the bottom end of the screw rod 3, a rubber pressure block 5 is installed on the bottom wall of the cross plate 4, limiting slide bars 6 are vertically arranged on both sides of the screw rod 3, a circular hole is opened on the cross beam of the frame 2, the limiting slide bar 6 slides in the circular hole, the bottom end of the limiting slide bar 6 is fixedly connected to the top wall of the cross plate 4, a limiting cap 7 is installed on the top end of the limiting slide bar 6, the bottom pressure surface of the rubber pressure block 5 is a semi-arc shape, and a hand wheel 11 is installed on the top end of the screw rod 3.
[0017] Specifically, the workpiece 12 can be clamped on the V-shaped groove of the V-shaped iron 1 by the rubber pressing block 5 .
[0018] During actual use, the workpiece 12 is first placed on the V-groove of the V-shaped iron 1, and then the handwheel 11 is rotated to make the screw 3 gradually descend, and the rubber pressure block 5 is gradually squeezed on the top wall of the workpiece 12, so that the workpiece 12 is clamped on the V-groove of the V-shaped iron 1 by the rubber pressure block 5 to prevent it from being randomly positioned or rotated; when the screw 3 gradually descends, the two limiting slide bars 6 slide in the circular hole, which can further limit the random rotation of the cross plate 4, so that the rubber pressure block 5 with a semi-arc bottom surface can be quickly and accurately pressed on the top wall of the workpiece 12, thereby improving its work efficiency; when processing bearing-type workpieces, the rubber pressure block 5 made of rubber material can avoid hard contact damage to its surface when clamping the workpiece.
[0019] like Figure 1 to Figure 2 As shown, a clamping device for workpiece processing is provided, wherein sliders 8 are installed at the two supporting bottom ends of the frame 2, and concave slide grooves 9 are provided on the two side walls of the V-shaped iron 1 in the extension direction, and the sliders 8 slide in the concave slide grooves 9, and second screw holes are provided horizontally on the two vertical beams of the frame 2, and top screws 10 are screwed in the second screw holes.
[0020] Specifically, by sliding the slider 8 in the concave slot 9, the clamping device can effectively clamp workpieces of different lengths and sizes, and also facilitates calibration, measurement or marking operations on the workpieces.
[0021] In actual use, when processing a longer workpiece, the slider 8 can be pushed to slide in the concave slide groove 9, so that the frame 2 is moved to the middle section of the V-shaped iron 1, and the middle section of the workpiece is clamped, so that the clamping force generated by the clamping device and the V-shaped iron 1 is in the middle section of the workpiece, so that the longer workpiece is clamped more firmly; when processing a shorter workpiece, the frame 2 can be moved to the end of the V-shaped iron 1, and the end of the workpiece can be effectively clamped.
