Abstract
The utility model discloses a wedge-shaped block for a rolling linear guide rail pair clamping device. The contact surface of the wedge-shaped block and a rolling column is divided into four sections, wherein the first section is a uniformly-accelerated motion curved surface, the second section is a large-angle constant-speed motion inclined surface, the third section is a uniformly-decelerated motion curved surface, and the fourth section is a small-angle constant-speed motion inclined surface. Due to the design, the wedge-shaped block disclosed by the utility model has the advantages that, the internal rigid impact of the wedge-shaped block at the moment of motion starting and the overhigh rigid impact on guide rails at the moment of motion stopping are effectively avoided, the response time is effectively shortened, and the stable clamping force is maintained, so that the wedge-shaped block can be widely applied to the rolling linear guide rail pair clamping device.
Description
Technical field
The utility model relates to a kind of braking device, specially refers to the wedge-shaped blocks on a kind of damping brake clamp that is applied in the Linear Rolling Guideways system.
Background technique
With reference to Fig. 1, present existing clamp is all to adopt air pressure to control, when opening baroswitch, produce thrust F by piston 1, and power and displacement are passed to wedge-shaped blocks 2, and make piston 1 and wedge-shaped blocks 2 be fixed together, make wedge-shaped blocks 2 produce mobile, key groove θ and roller 3 by wedge-shaped blocks 2 are realized reinforcement, promote brake slipper 4, it is pressed on the guide rail non-working surface, thereby produces powerful chucking power N, because the friction between brake slipper 4 and guide rail produces friction brake force R, realize braking.When closing baroswitch, wedge-shaped blocks 2 under the active force of spring 5, resets each several part.
Because the face of 2 thrust of wedge-shaped blocks becomes the θ oblique angle with horizontal axis.When wedge-shaped blocks 2 moved, brake slipper 4 will be with the uniform motion.By motion analysis as can be known, this characteristics of motion in motion beginning and moment of stopping due to velocity jump, this moment, theoretic accekeration was infinitely great (but due to the flexible distortion of material, in fact can not reach infinitely great), and its inertial force will cause rigid impulse.Therefore this wedge-shaped blocks 2 and the braking that the constant velocity motion that brake slipper 4 consists of moves make the existing occasion that device not too is adapted to high speed, heavy duty of clamping down on.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of by the parabolic motion motion that the utility model provides, and realizes the secondary guide rail clamp of the rolling linear wedge-shaped blocks of soft impulse.
The technological scheme that its technical problem that solves the utility model adopts is:
The secondary guide rail clamp of a kind of rolling linear wedge-shaped blocks, the surface of contact of described wedge-shaped blocks and roller is divided into four sections, and first paragraph is the uniform accelerated motion curved surface, and second segment is the uniform motion inclined-plane of wide-angle, the 3rd section is the uniform retarded motion curved surface, and the 4th section is low-angle uniform motion inclined-plane.
As further improvement in the technical proposal, the angle of inclination on the uniform motion inclined-plane of described wide-angle is 4 °～6 °; The angle of inclination on described low-angle uniform motion inclined-plane is 2 °～3 °.
Further, the length of described uniform accelerated motion curved surface is the buffer distance of wedge-shaped blocks; The length on the uniform motion inclined-plane of described wide-angle is the braking response distance of clamp; The length of described uniform retarded motion curved surface is the stopping distance of clamp; The length on described low-angle uniform motion inclined-plane is preset space after the braking of clamp.
the beneficial effects of the utility model are: the utility model is designed to the surface of contact of wedge-shaped blocks and roller on the variation curved surface of multistage, making wedge-shaped blocks can promote brake slipper first does uniform accelerated motion and carries out the uniform motion of wide-angle again, then carry out uniform retarded motion and carry out at last low-angle uniform motion, this design effectively avoided wedge-shaped blocks the motion beginning moment inside rigid impulse and the moment of termination guide rail is produced too high rigid impulse, and effectively shortened the response time, keep the stable power of clamping down on, thereby can be widely used on the secondary guide rail clamp of rolling linear.

Following accompanying drawing further illustrates the utility model.
Fig. 1 is the structural representation of existing linear rolling guide clamp;
Fig. 2 is structural representation of the present utility model.
Embodiment
with reference to Fig. 2, the secondary guide rail clamp of a kind of rolling linear wedge-shaped blocks, described wedge-shaped blocks 2 is divided into four sections with the surface of contact of roller 3, first paragraph is uniform accelerated motion curved surface 21, its length is the buffer distance of wedge-shaped blocks, the rigid impulse that the main buffering of this design wedge-shaped blocks 2 caused clamp inside in motion beginning moment, second segment is the uniform motion inclined-plane 22 of wide-angle, its length is the braking response distance of clamp, it is mainly for shortening the response time, this angle of inclination is 4 °～6 °, actual angle can be decided according to the actual size of roller 3, the 3rd section is uniform retarded motion curved surface 23, its length is the stopping distance of clamp, it is mainly the rigid impulse that produces be used to reducing 2 pairs of guide rails of wedge-shaped blocks, the 4th section is low-angle uniform motion inclined-plane 24, its length is preset space after the braking of clamp, because material deformation may occur or use wearing and tearing, be the reliability that can guarantee to brake, so having reserved should distance, thereby keep the stable power of clamping down on, this angle of inclination is 2 °～3 °, actual angle can be decided according to the actual size of roller 3.
The utility model is designed to wedge-shaped blocks 2 and the surface of contact of roller 3 on the variation curved surface of multistage, making wedge-shaped blocks can promote brake slipper first does uniform accelerated motion and carries out the uniform motion of wide-angle again, then carry out uniform retarded motion and carry out at last low-angle uniform motion, this design effectively avoided wedge-shaped blocks 2 the motion beginning moment inside rigid impulse and the moment of termination guide rail is produced too high rigid impulse, and effectively shortened the response time, keep the stable power of clamping down on, thereby can be widely used on the secondary guide rail clamp of rolling linear.
