Abstract
The utility model discloses a self-adjustable locking pressing plate which comprises a T-shaped locking bolt, a locking nut and a pressing plate, wherein the locking nut is in threaded connection with the T-shaped locking bolt, and the pressing plate is provided with a T-shaped locking bolt perforation and passes through the T-shaped locking bolt, wherein the two ends of the pressing plate are pressing ends. The self-adjustable locking pressing plate is characterized in that the pressing ends are of protruding arc structures. As the two ends are of arc structures, when the self-adjustable locking pressing plate rotates within a certain range, work pieces pressed by the two ends are always kept in linear contact, therefore, when pressing the work pieces, the self-adjustable locking pressing plate can normally press the work pieces without being limited by the fact that a cushion block needs to be in the same height as the work pieces; the time for adjusting the height of the cushion block is saved; and during single-piece processing of the work pieces which are different in height, the working efficiency of clamping the work pieces is greatly improved.
Description
Technical field
The utility model relates to pressing plate, particularly self-adjustable locking pressure plate, workpiece pressing in the single workpiece processing that is mainly used in.
Background technology
Fig. 1 is existing workpiece pressing plate, and it comprises the locking tommyhead bolt, and with the pressing plate that the locking tommyhead bolt is threaded locking nut, passes the locking tommyhead bolt and contact with locking nut, the pressing plate two ends are compressing end, and compressing end is a slab construction.This workpiece pressing plate only workpiece consistent with the height of cushion block in other words very near the time could workpiece pressing, yet in workpiece processing, the height of workpiece usually is different; Same workpiece at last just, it highly also is different when the different face of processing, this is the height that need adjust cushion block at any time, has increased the working time greatly, has increased cost of labor.
Summary of the invention
The purpose of the utility model provides a kind of in the single-piece work of differing heights workpiece in order to solve above-mentioned prior art problem, without the adjusting pad tile height, has improved the self-adjustable locking pressure plate of the operating efficiency of clamping workpiece greatly.
To achieve these goals; The self-adjustable locking pressure plate of the utility model; Comprise the locking tommyhead bolt; The locking nut that is threaded with the locking tommyhead bolt is locked the tommyhead bolt perforation and is passed the pressing plate of locking tommyhead bolt with offering, and the pressing plate two ends are compressing end, it is characterized in that compressing end is the arc structure of protrusion.
Connect when separating because have only when locking nut and hold-down plate surface; Compressing effect is only best; Compress effect in order to guarantee when workpiece height and cushion block height are inconsistent, not influence, the optimal technical scheme of the utility model is between pressing plate and locking nut, to be provided with the pressure core; Said pressure core is a hemispherical or half-cylindrical; Press the core tommyhead bolt that is locked to pass and the locking nut plane contact, in pressing plate, be provided with hemispherical or semi-cylindrical groove, press in the hemisphere face of core or semi-spherical grooves that semi-cylindrical places pressing plate or the semi-cylindrical groove and to contact with pressing plate hemisphere face or half-cylindrical face face.
Also can guarantee good result of use when making workpiece height and cushion block difference in height excessive, the solution of the utility model is: the locking tommyhead bolt perforation on the pressing plate along pressing plate longitudinally section be fan-shaped.
Arc-shaped structure is adopted at the utility model two ends; When doing the rotation of certain limit around the pressure core, it is that toe-in touches all the time that the workpiece place is pressed at two ends, so the restriction that not must equate with the workpiece height by cushion block; Workpiece pressing normally; Save the time of adjusting pad tile height, in the single-piece work of differing heights workpiece, improved the operating efficiency of clamping workpiece significantly.
Description of drawings
Fig. 1 is present pressure plate structure sketch map;
Fig. 2 is the utility model structure chart.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain:
Self-adjustable locking pressure plate shown in Figure 1; Comprise locking tommyhead bolt 5; The locking nut 1 that is threaded with the locking tommyhead bolt is locked the tommyhead bolt perforation and is passed the pressing plate 4 of locking tommyhead bolt with offering; The pressing plate two ends are the arc structure compressing end of protrusion, and between pressing plate 4 and locking nut 1, being provided with and pressing core 3, said pressure core is hemispherical or half-cylindrical; Press the core tommyhead bolt that is locked to pass and the locking nut plane contact; In pressing plate, be provided with hemispherical or semi-cylindrical groove, contact in the hemisphere face of pressure core or semi-spherical grooves that semi-cylindrical places pressing plate or the semi-cylindrical groove and with pressing plate hemisphere face or half-cylindrical face face, press between core 3 and the locking nut 1 and have additional packing ring 2.
More than be a specific embodiment of the utility model, yet those of ordinary skill in the art still can make the protection domain that the scheme that does not break away from the utility model still falls into the utility model.
Claims (3)
1. self-adjustable locking pressure plate; Comprise the locking tommyhead bolt; The locking nut that is threaded with the locking tommyhead bolt is locked the tommyhead bolt perforation and is passed the pressing plate of locking tommyhead bolt with offering, and the pressing plate two ends are compressing end, it is characterized in that compressing end is the arc structure of protrusion.
2. self-adjustable locking pressure plate according to claim 1; It is characterized in that between pressing plate and locking nut, being provided with the pressure core; Said pressure core is a hemispherical or half-cylindrical; Press core to pass locking tommyhead bolt and locking nut plane contact, in pressing plate, be provided with hemispherical or semi-cylindrical groove, contact in the hemisphere face of pressure core or semi-spherical grooves that semi-cylindrical places pressing plate or the semi-cylindrical groove and with pressing plate hemisphere face or half-cylindrical face face.
3. self-adjustable locking pressure plate according to claim 1 and 2, it is characterized in that on the pressing plate locking tommyhead bolt perforation along pressing plate longitudinally section be fan-shaped.
