Description

A clamp type flexible clamping tool

technical field

The utility model relates to the field of mechanical manufacturing, in particular to a pliers-type flexible clamping tool, which is used for processing large mold parts.

Background technique

In the production work, the existing large model parts are processed and clamped by putty bonding. This processing method not only wastes auxiliary materials, but also needs to wait for the points to solidify before processing, which increases additional waiting auxiliary time. Sometimes If the putty is not strong enough, the workpiece will "fly off"; and for parts that need to be turned over for processing, it needs to be reversed and turned twice for positioning before processing, which will have a slight impact on the accuracy of the part.

Therefore, it is necessary to find a better clamping method for model processing. However, ordinary bench vises are limited by the size of the jaws and can only clamp small parts. As shown in Figure 1, a common bench vise clamping method in the prior art, the heights of the fixed clamping block and the movable clamping block are all low, and can only be used for direct clamping of smaller workpieces, and Usually used for single-sided machining of workpieces.

The clamping block and the movable clamping block are arranged face to face, and the clamping space between the fixed clamping block and the movable clamping block can be changed by adjusting the movable clamping block.

Wherein, the width of the raising block is smaller than the width of the clamping space between the fixed part of the jaw and the movable part of the jaw.

Wherein, the first mounting seat is L-shaped, including a first fixing surface and a first mounting surface perpendicular to each other, and the fixed clamping block is fixedly connected to the first mounting surface; the second mounting seat is also It is L-shaped and includes a second fixed surface and a second installation surface perpendicular to each other, and the movable clamping block is movably installed on the second installation surface.

Wherein, a plurality of threaded fixing holes are opened on the first fixing surface and the second fixing surface.

detailed description

Below in conjunction with specific embodiment and accompanying drawing, further elaborate the utility model.

As shown in Figure 2, a pliers-type flexible clamping tool includes a relatively installed jaw fixed part 1 and a jaw movable part 2, and a pad installed between the jaw fixed part 1 and the jaw movable part 2 Block 4.

The jaw fixing part 1 includes a first mounting base 11 and a fixed clamping block 12 fixed on the first mounting base 11 . The first installation seat 11 is L-shaped, and includes a first fixing surface 111 and a first installation surface 112 perpendicular to each other, and the fixed clamping block 12 is fixedly connected to the first installation surface 112 . Threaded fixing holes are provided on the first fixing surface 111 for fixing the position of the first mounting base 11 .

The jaw movable part 2 includes a second mounting base 21 and a movable clamping block 22 movably mounted on the second mounting base 21 , and the fixed clamping block 12 and the movable clamping block 22 are arranged face to face. The second mounting base 21 is also L-shaped and includes a second fixing surface 211 and a second mounting surface 212 perpendicular to each other. A plurality of threaded fixing holes are provided on the second fixing surface 211 for fixing the position of the second mounting seat 21 . Two through holes are symmetrically opened on the second mounting surface 212 along the horizontal direction, and a threaded adjustment hole is opened between the two through holes. Two guide rods 23 are provided on the side of the movable clamping block 22 opposite to the second mounting surface 212 corresponding to the positions of the two through holes, and the two guide rods 23 are respectively inserted into the two through holes. On the opposite side of the movable clamping block 22 to the second mounting surface 212, a circular groove is provided at the position corresponding to the screw adjusting hole, and an adjusting screw 24 is arranged in the screw adjusting hole, and one end of the adjusting screw 24 abuts against the circular groove. The bottom of the shaped groove. Rotating the adjusting screw 24 makes the movable clamping block 22 move horizontally, so as to change the clamping space between the fixed clamping block 12 and the movable clamping block 22 .

The raising block 4 is located in the clamping space between the fixed clamping block 12 and the movable clamping block 22, so the width of the raising block 4 is smaller than the clamping space between the fixed clamping block 12 and the movable clamping block 22 width.

The clamping tool can be used for double-sided processing of workpieces. Considering that the turning workpiece needs to be fixed by bolts, the first mounting surface 112 and the second mounting surface 212 are higher than ordinary bench vices, so when clamping the workpiece 3 , a certain space can be reserved at the bottom of the workpiece for fixing bolts on the opposite side of the workpiece, and the bottom of the workpiece 3 can be installed with a riser 4 as required, as shown in Figure 3. In this way, the secondary disassembly and assembly of the mounting bolts is avoided, and the workpiece can be directly fixed and processed by the mounting bolts in the bottom space.

The clamping tool can also be used in conjunction with the mounting base 5. A plurality of mounting holes 51 are regularly arranged at equal intervals on the mounting base 5. The mounting holes 51 can be threaded holes and/or pin holes. According to the size of the workpiece, the jaw fixed part 1 and the jaw movable part 2 of the clamping tool are installed on the mounting base 5 through the mounting hole 51, as shown in FIG. 4 . The joint use of the clamping tool and the installation base 5 can realize arbitrary adjustment of the range of clamping, increase or decrease of the number of clamping positions, so that the clamping of the workpiece has great flexibility.

The above-mentioned embodiments are provided for those who are familiar with the field to realize or use the utility model. Those who are familiar with the field can make various modifications or modifications to the above-mentioned embodiments without departing from the utility model idea of the present utility model. Therefore, the scope of protection of the utility model is not limited by the above-mentioned embodiments, but should be the maximum range that meets the innovative features mentioned in the claims.
