Abstract
The utility model discloses a wedge-shaped block used on a clamp of a linear rolling guide pair. The contact surface of the wedge-shaped block with a rolling column is a variable curved surface which can enable a brake block to make uniform accelerated motion when starting braking and make uniform decreasing motion when approaching braking state. The design effectively avoids that the wedge-shaped block generates rigid impact on a guide rail at the moment of motion starting and stopping, the contact line of the wedge-shaped block with the rolling column forms the minimal inclination angle in the variable curved surface when the wedge-shaped block is in braking locking state, so that the clamping force is maximal and stable.
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 clamping device that is applied in the linear rolling guide system.
Background technique
With reference to Fig. 1, present existing clamping device all is to adopt air pressure control, when opening baroswitch, produce thrust F by piston 1, and power and displacement passed to wedge-shaped blocks 2, and make piston 1 and wedge-shaped blocks 2 be fixed together, make wedge-shaped blocks 2 produce and move, 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-produced friction brake force R between brake slipper 4 and the guide rail realizes braking.When closing baroswitch, then wedge-shaped blocks 2 resets each several part under the active force of spring 5.
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 motion beginning and moment of stopping because velocity jump, this moment, theoretic accekeration was infinitely great (but because in fact the flexible distortion of material 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 constitutes moves make that existing strangulation device not too is adapted at a high speed, the occasion of heavy duty.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of and quickens the uniform retarded motion regular movement by waiting, and realizes the linear rolling guide clamping device of soft impulse.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of wedge-shaped blocks that is used on the linear rolling guide clamping device, the surface of contact of described wedge-shaped blocks and roller is for changing curved surface, and this curved surface can make brake slipper do uniform accelerated motion when beginning to brake, and does uniform retarded motion during near braking state;
As further improvement in the technical proposal, described wedge-shaped blocks is when the braking and locking state, and the Line of contact of wedge-shaped blocks and roller is in the tilt angle that changes curved surface and is minimum.
The beneficial effects of the utility model are: the utility model is designed to change curved surface with the surface of contact of wedge-shaped blocks and roller, make wedge-shaped blocks can promote the brake slipper work and wait moving of decelerations such as acceleration, back earlier, thereby avoided wedge-shaped blocks guide rail to be produced rigid impulse in the moment of motion beginning and termination, and wedge-shaped blocks is when the braking and locking state, the Line of contact of wedge-shaped blocks and roller is in the tilt angle that changes curved surface and is minimum, makes chucking power maximum and stable.
Description of drawings
Following accompanying drawing further specifies the utility model.
Fig. 1 is the structural representation of existing linear rolling guide clamping device;
Fig. 2 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 2, a kind of wedge-shaped blocks that is used on the linear rolling guide clamping device, described wedge-shaped blocks 2 is variation curved surface 21 with the surface of contact of roller 3, this curved surface 21 can make brake slipper 4 do uniform accelerated motion when beginning to brake, and do uniform retarded motion during near braking state, this design has effectively avoided wedge-shaped blocks 2 in motion beginning and moment of stopping guide rail to be produced rigid impulse.
In addition, force analysis by brake slipper 4 as can be known, if will increase chucking power N, the best way is the size that changes point of contact place tiltangle, θ is more little, and strangulation power is big more, and drag friction power R is also big more, and along with the change confining force of tiltangle change very remarkable, so the tiltangle of wedge-shaped blocks 2 and the surface of contact of roller 3 has decisive influence to the size of braking force.Along with the wearing and tearing in the running, point of contact present position difference, the braking force size also can change, the braking process instability.May cause the actual braking force deficiency of clamping device when serious, cause package unit braking effect deviation.Therefore, for guaranteeing enough stable strangulation power is arranged when the strangulation, should guarantee as far as possible that basically identical and as far as possible little is answered at the second half section tilt angle of wedge shape curve.Described wedge-shaped blocks 2 is when the braking and locking state, and the Line of contact of wedge-shaped blocks 2 and roller 3 is in the tilt angle that changes curved surface 21 and is minimum, thereby guarantees chucking power N maximum and stable.
