Abstract
Description
Technical Field
[0001] The invention relates to a clamp, in particular to a grinder flat-nose pliers. Background Art
[0002] Flat-nose pliers, also known as machine vises, are a general-purpose clamp that is often used to install small workpieces. They are random accessories for milling machines and drilling machines. They are fixed on the machine tool workbench to clamp the workpiece for cutting. When the flat-nose pliers are working, the lead screw is turned with a wrench, and the movable pliers body is driven to move through the lead screw nut to tighten and loosen the workpiece. However, the existing flat-nose pliers only have a coarse adjustment function, which directly presses the product through the lead screw. The above method is prone to two problems: one is that the fixed product is easy to warp up; the other is that the clamping force actually transmitted to the clamped workpiece is small. Therefore, in response to the above needs, it is necessary to propose further solutions. Summary of the invention

[0014] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0015] Figure 1 It is a three-dimensional schematic diagram of a specific embodiment of the grinding machine flat-nose pliers of the present invention;
[0016] Figure 2 for Figure 1 Cross-section view in the AA direction;
[0017] Figure 3 for Figure 1 Cross-sectional view along the BB direction. DETAILED DESCRIPTION
[0018] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.
[0019] like Figure 1 As shown, the grinding machine flat-nose pliers of the present invention include: a body 1, a fixed end 2, a movable end 3 and a screw rod 4.
[0020] The fixed end 2 is fixed to one end of the body 1, one end of the screw rod 4 is fixedly connected to the fixed end 2, and the screw rod 4 passes through the movable end 3 and is threadedly connected to the movable end 3. Thus, by rotating the screw rod 4, the movable end 3 can be roughly controlled to move closer to or away from the fixed end 2, so as to achieve the balance of the clamping force, reduce the influence of the deformation of the clamping transmission part under the action of the clamping force on the clamping accuracy, and enhance the clamping stability of the workpiece.
[0021] Furthermore, the body 1 is provided with a third slide groove 11, the screw rod 4 is received in the third slide groove 11, and the mobile end 3 slides along the third slide groove 11. In order to ensure the sliding stability of the mobile end 3, step surfaces are respectively provided on the opposite sides of the third slide groove 11, so that the mobile end 3 can slide along the step surfaces, thereby guiding the mobile end 3.
[0022] In addition, the other end of the screw rod 4 is also provided with a hand wheel 41, and the hand wheel 41 is fixed to the other end of the screw rod 4 by a fastening screw. At the same time, a plurality of holes are also provided on the peripheral wall surface of the hand wheel 41. When rotating the screw rod 4, a wrench can be inserted into the hole, and the screw rod 4 can be conveniently driven to rotate by using the lever principle.
[0023] like Figure 2 As shown, the fixed end 2 includes: a housing 21 and a movable block 22 located in the housing 21, one end of the screw rod 4 is fixedly connected to the movable block 22, and a buffer gap is provided between the movable block 22 and the housing 21. This is conducive to buffering the interaction between the screw rod 4 and the fixed end 2, and avoiding wear of the flat-nose pliers over a long period of time.
[0024] The moving end 3 comprises: a positioning block 31, a pressing block 32 and a sliding block 33. The pressing block 32 is located between the positioning block 31 and the sliding block 33, and the screw rod 4 passes through the positioning block 31 and is threadedly connected with the positioning block 31.
[0025] The pressing block 32 has a first inclined surface 321 facing the slider 33 and a second inclined surface 322 facing the positioning block 31. The first inclined surface 321 and the second inclined surface 322 gradually approach each other from top to bottom, so that the pressing block 32 is roughly an inverted trapezoidal structure. A vertically arranged first screw 5 runs through the pressing block 32.
[0026] The pressing block 32 is connected to the sliding block 33 and the positioning block 31 through a second screw 6. A first sliding groove 3211 is provided on the first inclined surface 321, and a second sliding groove 3221 is provided on the second inclined surface 322. The nut of the second screw 6 slides along the corresponding sliding groove.
[0027] Thus, when the first screw 5 is rotated, the pressing block 32 moves toward the positioning block 31 through the screw connection. At the same time, since the mating surfaces between the pressing block 32, the positioning block 31 and the sliding block 33 are inclined surfaces, and the positioning block 31 is fixed by the thread on the screw rod 4, the pressing block 32 pushes the sliding block 33 toward the fixed end 2 by fine adjustment, further clamping and fixing the workpiece to prevent the workpiece from warping up.
[0028] like Figure 3 As shown, in order to avoid the stability of the movement of the pressing block 32, the movable end 3 also includes a pressing plate 7, which is located in the receiving groove at the top of the pressing block 32 and is fixedly connected to the positioning block 31 by a third screw 8 that penetrates the pressing block 32. The nut of the first screw 5 is threadedly connected to the pressing block 32. The third screw 8 is distributed on both sides of the first screw 5, and the nut of the third screw 8 rests on the table surface of the pressing plate 7. At the same time, a spring 9 is also mounted on the third screw 8, and the spring 9 is located between the pressing block 32 and the positioning block 31. Therefore, when the first screw 5 is rotated, the pressing block 32 can slide up and down stably along the third screw 8.
[0029] In summary, the grinder flat-nose pliers of the present invention have two adjustment modes: continuous coarse adjustment and fine adjustment. The force of the clamping system (movable block-screw rod-positioning block) is in a balanced state, and the deformation caused by the force affects the clamping accuracy of the fixed end and the movable end as little as possible, thus avoiding the problems existing in the method of relying solely on coarse adjustment. At the same time, the clamping effect is improved through fine adjustment, the product is prevented from warping up, and the stability of the clamping is ensured.
