Abstract
The utility model discloses a positioning clamping block combined fixture composed of two pairs of positioning clamping block fixtures with the same structure. Each positioning clamping block fixture comprises a lower positioning block and an upper clamping block; a key matched with a T-shaped groove is formed on the bottom surface of each lower positioning block and a first T-shaped bolt and a second T-shaped bolt are arranged on each lower positioning block at an interval; the head parts of the first and second T-shaped bolts are located under the lower positioning block and inserted into the T-shaped groove; a section of upper inclined surface is formed on the top surface of the lower positioning block; the second T-shaped bolt penetrates through the upper inclined surface; a waist-shaped hole allowing the second T-shaped bolt to pass through is formed on the upper clamping block; and a section of lower inclined surface matched with the upper inclined surface is formed on the bottom surface of the upper clamping block. The positioning clamping block combined fixture is convenient, fast, time-saving and labor-saving in the operation of clamping a workpiece, and realizes coarse and fine processing of the upper and side planes and grooves through once clamping; and the positioning clamping block combined fixture is good in universality and wide in application range, and can be formed into the common fixture for popularization and use. Besides, the positioning clamping block combined fixture is capable of reducing the labor intensity of an operator, reducing the auxiliary time and improving the production efficiency.
Description
Technical field
The utility model relates to field of machining, particularly is applied to the location clamp built-up jig on the T type guide pass.
Background technology
In the middle of machining equipment; A lot of equipment such as planer, milling machine, drilling machine etc. all have T type groove workbench; Effect is to install like flat-nose pliers, the first-class universal fixturing of calibration; Or above directly being installed in workpiece to be processed, utilize clamping devices such as T type groove, T type bolt, nut, pressing plate, workpiece is positioned processing.But for thick, the fine finishining of big-and-middle-sized workpiece, like the processing square cross, not allowing has any false boss or fabrication hole before the processing; And the planing of workpiece planarization, Milling Process add and can not accomplish whole processing by one-pass man-hour, because cutter can interfere with pressing plate and bolt usually with T type bolt, pressing plate clamping work pieces location; Must in the feeding process, stop; Change clamping position, interrupted cut so just occurs and connect the cutter phenomenon, cause the decline of quality and production efficiency.For this reason, designed and produced location clamp anchor clamps, in production practices, obtained using widely.
The utility model content
The utility model technical problem to be solved is to add to existing big-and-middle square cross plane and can not accomplishes whole the existing deficiency of processing and a kind of novel location clamp built-up jig is provided by one-pass man-hour, and the size of this built-up jig can adjust according to equipment, workpiece situation.Size is meant the groove width, wide, the T type bolt of design key of T type groove, locating piece bolt slot and aperture etc. up and down.
The utility model technical problem to be solved can realize through following technical scheme:
Location clamp built-up jig; Form by two pairs of identical location clamp anchor clamps of structure; Said location clamp anchor clamps comprise locating piece and upper clamping block down; The said bottom surface of locating piece down is provided with the key that cooperates with T type groove, on this time locating piece, is arranged at intervals with a T type bolt and the 2nd T type bolt, and the head of first, second T type bolt is positioned at the below of said locating piece down and inserts T type groove; Be provided with one section ramp at said locating piece end face down, the 2nd T type bolt passes said ramp; Said upper clamping block is provided with the mounting hole that a confession the 2nd T type bolt passes, and is provided with one section lower inclined plane that matches with said ramp in the bottom surface of upper clamping block.
The operation principle of the utility model is: during clamping workpiece; Two pairs of identical location clamp anchor clamps symmetries of structure are placed into the both sides of workpiece; According to locating piece position under the adjustment earlier of clamping distance situation; Screw up with a wrench then nut on the T type bolt is clamped on the workbench locating piece location.Upper clamping block can have the front and back slippage on the ramp of following locating piece; Apply moment of torsion with spanner and tighten the nut on the 2nd T type bolt; Generation is to the vertical of upper clamping block; Make the upper clamping block contact workpiece, vertical force F produces frictional force, finally under normal pressure and function of friction, makes workpiece realize clamping and positioning.
These anchor clamps clamping workpiece is easy to operate, quick, save time, laborsaving, realized that disposable clamping can be accomplished, side plane and groove slightly, fine finishining.Versatility is good, and is applied widely, can be made into universal fixturing and popularize use.Reduce operator's labour intensity, reduce non-cutting time, enhance productivity.
Description of drawings
Fig. 1 is the structural representation of the utility model location clamp anchor clamps.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation that the utility model location clamp built-up jig clamps square part.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
The location clamp built-up jig of the utility model is made up of two pairs of identical location clamp anchor clamps of structure.Referring to Fig. 1 and Fig. 2; Location clamp anchor clamps shown in the figure comprise locating piece 100 and upper clamping block 200 down; The bottom surface of following locating piece 100 is provided with the key 210 that cooperates with T type groove, on this time locating piece 100, is arranged at intervals with T type bolt 120,130, and the head of T type bolt 120,130 is positioned at the below of following locating piece 100 and inserts T type groove; Be provided with one section 25 ° ramp 140 at following locating piece 100 end faces, T type bolt 130 passes ramp 140; Upper clamping block 200 is provided with the mounting hole 210 that a confession T type bolt 130 passes, and is provided with one section 25 ° of lower inclined plane 220 that match with ramp 140 in the bottom surface of upper clamping block 200.
Referring to Fig. 3; During clamping workpiece 300; Two pairs of identical location clamp anchor clamps symmetries of structure are placed into the both sides of workpiece 300; According to locating piece 100 positions under the adjustment earlier of clamping distance situation, the nut 121 on the T type that screws up with a wrench the then bolt 120 is clamped on the workbench 400 locating piece 100 location.Upper clamping block 200 can have the front and back slippage on the ramp 140 of following locating piece 100; Apply moment of torsion with spanner and tighten the nut 131 on the T type bolt 130; Generation is to the vertical of upper clamping block 200; Make upper clamping block 200 contact workpieces 300, vertical force F produces frictional force, finally under normal pressure and function of friction, makes workpiece 300 realize clamping and positioning.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
