The utility model discloses a clamp device, relates to improvement of structures of clamp devices, and provides a fixture which is simple in structure, convenient to use, and capable of effectively avoiding shifting of workpieces. The clamp device comprises an upper clamp and a lower clamp, wherein the upper surface of the lower clamp is provided with lower clamping teeth in a sawtooth shape, and the sawtooth ridge lines of the lower clamping teeth are perpendicular to the length direction of the clamp body of the lower clamp; a plurality of upper clamping bolts installed above the lower clamping teeth are installed at the end of the upper clamp, each upper clamping bolt comprises an upper portion and a lower portion which is connected with each upper portion into a whole, the upper clamping bolts are fixedly connected inside the upper clamp through the upper portions, and the lower portions of the upper clamping bolts are in a polygon prism shape; and the bottom edges of the lower portions of the upper clamping bolts and the sawtooth ridge lines of the lower clamping teeth are staggered. The clamp device can effectively overcome the defect that the workpieces shift along the sawtooth ridge lines of the lower clamping teeth during transferring and processing procedures, and can effectively resolve the problems that shifting of the workpieces during a clamping procedure leads to poor processing accuracy, a high rejection rate and the like.

Description

Gripping mechanism

Technical field

The utility model relates to field of machining, relates in particular to the improvement of the structure of gripping mechanism.

Background technology

Along with the automated production level of machining is more and more higher, feasible clamp method to workpiece becomes more and more important.If clamp not strongly and lean on, then can cause workpiece occurrence positions in process to change, and produce either large or small mismachining tolerance, like this, will directly bring problems such as machining accuracy is poor, percent defective height.For solving this type of problem, State Bureau has announced a " spraying tin on circuit board anchor clamps " by name on June 17th, 2009, application number is the file of " 200820160246.5 ", utilize the zigzag catch on top and latch and the zigzag clamp of bottom to cooperatively interact in this device, one realizes the function to piece-holder.

Yet we find in daily production and processing, when plate, sheet-like workpiece carry out clamping with the zigzag anchor clamps in above-mentioned, easily take place along the skew of the crestal line direction of sawtooth in its transhipment, the process.Like this, though make these type of anchor clamps clamp workpiece, but can't effectively avoid problems such as machining accuracy is poor, percent defective height.

Summary of the invention

The utility model provides a kind of simple in structure, easy to use at above problem, and can effectively avoid the anchor clamps of workpiece skew.

The technical solution of the utility model is: comprise clamp and following clamp,

Described clamp upper surface down is provided with jagged latch down, and the crestal line of the described sawtooth of latch down is perpendicular to the described length direction of the caliper of clamp down;

Described end of going up clamp is provided with some last bails that are located at described latch down top, and the described bail of going up comprises the upper and lower that is connected as a single entity and be fixedly connected on described going up in the clamp by top that the described upward bottom of bail is multi-edge column-shaped;

The crestal line of the basal edge of the described upward bottom of bail and the described sawtooth of latch down is staggered.

Described go up clamp monosymmetric is provided with a pair of limited block, and a pair of described limited block is fixedly connected on the upper surface of described clamp down.

The basal edge (being an incline of bottom bottommost) that to go up the bottom of latch in the utility model is staggered with the crestal line of the sawtooth of following latch.Like this, utilize staggered basal edge and crestal line can be effectively workpiece to be limited along the movement of the crestal line direction of the sawtooth of latch down, thereby, can effectively avoid workpiece in the process of transhipment, processing, take place along under the skew of crestal line direction of sawtooth of latch, can effectively solve problems such as the machining accuracy that causes is poor, percent defective height have taken place to be offset in clamping process because of workpiece.

In addition, the utility model also is provided with a pair of limited block at the caliper of last clamp monosymmetric, utilizes limited block can effectively avoid when clamping, the skew of the workpiece that the skew that takes place because of last clamp causes.

The specific embodiment

The utility model comprises clamp 1 and following clamp 2 shown in Fig. 1-9,

Described clamp 2 upper surfaces down are provided with jagged latch 21 down, and the crestal line of the described sawtooth of latch 21 down is perpendicular to the described length direction of the caliper of clamp 2 down;

Described end of going up clamp 1 is provided with some described last bails 11 of latch 21 tops down that are located at, the described bail 11 of going up comprises the top 111 that is connected as a single entity and bottom 112 and is fixedly connected on described going up in the clamp 1 by top 111 that described bottom 112 of going up bail 11 is multi-edge column-shaped (as shown in Figure 9);

The basal edge (being an incline of bottom 112 bottommosts) of the described upward bottom 112 of bail 11 is staggered with the crestal line of the described sawtooth of latch 21 down.Like this, utilize staggered basal edge and crestal line can be effectively workpiece to be limited along the movement of the crestal line direction of the sawtooth of latch 21 down, thereby, can effectively avoid workpiece in the process of transhipment, processing, take place along under the skew of crestal line direction of sawtooth of latch 21, can effectively solve problems such as the machining accuracy that causes is poor, percent defective height have taken place to be offset in clamping process because of workpiece.

Described go up clamp 1 monosymmetric is provided with a pair of limited block 10, and a pair of described limited block 10 is fixedly connected on the upper surface of described clamp 2 down.Can effectively avoid when the clamping skew of the workpiece that the skew that takes place because of last clamp 1 causes by a pair of limited block 10.

Technique effect of the present utility model is: make its structure simple more, use conveniently, also efficiently solve simultaneously problems such as the machining accuracy that causes is poor, percent defective height take place to be offset in clamping process because of workpiece.
