Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Detailed description of the preferred embodiment

As shown in fig. 1, the utility model discloses a batch adjustable clamping mechanism, which structurally comprises a bottom plate 1, a pressing rod 2, a movable plate 3 and a pressing bolt 5. A station plate 11 is fixed on the bottom plate 1, a plurality of V-shaped grooves (the number of the V-shaped grooves is not particularly limited, three are taken as an example in the figure, and three are not specified) are formed by recessing the station plate 11 downward, each V-shaped groove is a fixing station 111, and the fixing stations 111 are used for clamping the shaft parts 6.

The bottom plate 1 is provided with a support plate 12 below the fixed station 111 on the station plate 11, the support plate 12 is provided with through holes corresponding to the fixed station 111 one by one, each through hole is internally provided with a pressing rod 2 to pass through, the upper part of each pressing rod 2 is narrow and wide, the bottom radius is larger than the radius of the through hole, and a spring 4 is arranged between the bottom of each pressing rod 2 and the through hole of the support plate 12.

The bottom plate 1 is provided with a fixing piece 13 below the supporting plate 12, the fixing piece 13 is provided with a through hole, and the pressing bolt 5 is fixed on the bottom plate 1 through the through hole on the fixing piece 13 and can do telescopic motion in the through hole of the fixing piece 13. One end of the pressing bolt 5 penetrating through the through hole on the fixing member 13 is connected with the movable plate 3, and the movable plate 3 can move along with the expansion and contraction of the pressing bolt 5.

When needing tight axle type part 6 of batch clamp, only need locking clamp bolt 5, clamp bolt 5 drives fly leaf 3 extrusion pressing rod 2 and compresses tightly axle type part 6, and the setting up of V word groove makes pressing rod 2 impress axle type part 6 in fixed station 111 when fixed in the middle of the V type groove because of the centering effect of circular structure certainly of compressing tightly pole 2. Meanwhile, the outer diameter error between the same-batch shaft parts in the precision machining field is small, and under the pressing force of the same pressing bolt 5, the spring 4 with the large outer diameter compresses a large point, and the spring 4 with the small outer diameter compresses a small point. The external diameter error of the shaft parts 6 which possibly exist in the batch clamping process can be effectively eliminated, so that the clamping process of the whole shaft parts 6 is accurate and efficient.

When the shaft parts 6 need to be taken down in batches, only the hold-down bolt 5 needs to be loosened, and the hold-down rod 2 is popped up downwards under the action of the restoring elastic force of the spring 4, so that the quick disassembly of the shaft parts 6 in batches is realized.

Detailed description of the utility model

As shown in fig. 2, the difference between the first embodiment and the second embodiment is mainly that: a plurality of adjusting rods 7 are arranged between a pressing rod 2 and a movable plate 3 of the batch adjustable clamping mechanism.

The support plate 12 extends left and right downwards to form a side wall, and the side wall of the support plate 12 and the movable plate together define a movable chamber of the adjusting rod 7. The adjusting rods 7 are arranged in double rows, the number of the adjusting rods 7 in the first row is the same as that of the pressing rods 2, the number of the adjusting rods 7 in the second row is one less than that of the first row, and the adjusting rods 7 which are adjacent up and down are arranged in a staggered mode.

When the shaft parts 6 need to be clamped in batches, only the compression bolts 5 need to be locked, the compression bolts 5 drive the movable plate 3 to extrude the double-row adjusting rods 7, the first row adjusting rods 7 extrude the compression rods 2 to compress the shaft parts 6, and the arrangement of the V-shaped grooves enables the compression rods 2 to be centered and fixed in the V-shaped grooves due to the self-centering effect of the circular structure when the shaft parts 6 are pressed into the fixing station 111. Meanwhile, the outer diameter error between the same batch shaft parts in the precision machining field is small, the spring 4 with the large outer diameter compresses a large point, and the spring 4 with the small outer diameter compresses a small point under the pressing force of the same pressing bolt 5, so that the possible outer diameter error of the shaft parts 6 can be effectively eliminated in the batch clamping process. The staggered arrangement of the double rows of adjusting rods 7 enables the positions of the adjacent adjusting rods 7 to be freely adjusted within a clearance range due to the self-centering action of the circular structure, so that the outer diameter error of the shaft parts 6 is further eliminated, and the rapid and stable clamping of batch parts is realized.

The most obvious beneficial effects of the present embodiment over the first embodiment are as follows: in the first concrete embodiment, when the size difference of the shaft parts 6 to be replaced is large, the matching among the pressing rod 2, the spring 4 and the movable plate 3 is required to be debugged, and the first concrete embodiment can be used for adapting to the clamping requirements of the shaft parts 6 with different sizes by replacing the adjusting rods 7 with different diameters, so that the debugging frequency of the equipment is greatly reduced, and the working efficiency is improved.
