Description

Technical Field

[0001] This invention belongs to the field of grinding machine technology, and specifically relates to an adjustable grinding machine flat jaw vise. Background Art

[0002] In machining, surface grinding is a commonly used technique. It involves using magnetism to attract the product onto the worktable of a surface grinder, and then grinding the product's upper surface. However, some non-ferrous metals (such as aluminum and copper alloys) and non-metals (such as carbon fiber and ceramics) are not affected by magnetic attraction and cannot be attracted onto the worktable of the surface grinder, making positioning difficult during grinding. For such materials, milling or turning followed by polishing is generally used, which is costly and makes it difficult to guarantee accuracy. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an adjustable grinding machine vise that is simple in structure, easy to operate, and capable of positioning products that cannot be adsorbed on a surface grinder on the grinder, thereby ensuring product quality.

[0004] The technical solution adopted in this invention is as follows: an adjustable grinding machine vise, comprising a vise base, a movable positioning vise, a bevel clamping vise, and a pressure plate; the vise base has a boss I with an isosceles trapezoidal cross-section in the middle; multiple grooves are provided parallel to each other on both sides of the boss I on the vise base, the grooves having an isosceles trapezoidal cross-section with the upper base larger than the lower base, and a rectangular cross-section at the bottom; the movable positioning vise has two bosses II with an isosceles trapezoidal cross-section on its bottom surface, and the two bosses II respectively mate with the two grooves on the vise base; the pressure plate has bolt holes in the middle, and is installed on the boss I by bolts; the pressure plate has two sets of long straight holes, the length direction of which is perpendicular to the grooves on the vise base; each long straight hole has a screw, and each set of screws connects to the same bevel clamping vise, the two bevel clamping vises forming a V-groove, which mates with the boss I.

[0005] In the aforementioned adjustable grinding machine flat-jaw vise, the movable positioning vise is provided with screw holes, which are located between two bosses II. A screw is provided in the screw hole, and the lower end of the screw is placed in a groove in the vise seat.

[0006] In the aforementioned adjustable grinding machine flat jaw vise, the upper parts of the two inclined clamping jaws are connected by several return springs, and the axis of the return springs is parallel to the length direction of the long straight hole.

[0007] In the aforementioned adjustable grinding machine vise, each group of long straight holes contains two long straight holes.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This invention features a simple structure and low cost. In use, the position of the movable positioning jaws is adjusted according to the product dimensions. The bottom of the jaw base is then attached to the worktable of the surface grinder. The part is then loaded, and the bolts are rotated to move the inclined clamping jaws downwards to clamp the part. After grinding, the bolts are loosened, and the return spring causes the pressure plate to rise, releasing the part from the inclined clamping jaws. This invention is convenient to operate and enables the grinding of parts that cannot be attached to the worktable of a surface grinder, ensuring product quality. Attached Figure Description

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] like Figure 1-6 As shown, the present invention includes a clamp base 1, a movable positioning clamp 2, a beveled clamping clamp 3, and a pressure plate 4. A boss I11 is provided in the middle of the clamp base 1, and the cross-section of the boss I11 is an isosceles trapezoid with the upper base smaller than the lower base. Multiple grooves 12 are provided parallel to each other on both sides of the boss I11 on the clamp base 1. The cross-section of the grooves 12 is an isosceles trapezoid with the upper base larger than the lower base, and a rectangle at the bottom.

[0018] The movable positioning clamp 2 has two protrusions II 21 with an isosceles trapezoidal cross-section on its bottom surface, and the two protrusions II 21 are arranged in parallel. The two protrusions II 21 respectively mate with two grooves on the clamp base. The movable positioning clamp 2 has a screw hole 22, which is located between the two protrusions II 21. A screw 5 is installed in the screw hole 22, and the lower end of the screw 5 is placed in a groove 12 of the clamp base 1.

[0019] The pressure plate 4 has a bolt hole 41 in the middle, which is used to install it on the boss I11 by bolts 6. The pressure plate 4 has two sets of long straight holes 42, the length direction of which is perpendicular to the groove 12 on the clamp seat. There are two long straight holes in each set of long straight holes 42. Each long straight hole contains a screw, and each set of screws connects to the same inclined clamp 3. The two inclined clamps 3 form a V-shaped groove, which mates with the boss I11. The upper parts of the two inclined clamps 3 are connected by several return springs 7, the axis of which is parallel to the length direction of the long straight holes 42.

[0020] In use, this invention involves adjusting the position of the movable positioning clamp 2 according to the dimensions of the product clamping location, attaching the bottom of the clamping seat 1 to the worktable of the surface grinder, and then loading non-ferrous metal or non-metal parts that cannot be attached to the worktable. Tightening the bolt 6 moves the inclined clamping clamp 3 downwards to clamp the parts. After grinding, loosening the bolt 6 causes the pressure plate 4 to rise under the force of the return spring 7, releasing the parts from the inclined clamping clamp 3. This achieves the grinding of parts that cannot be attached to the worktable of the surface grinder, ensuring product quality.
