Description

Directional regulating mechanism

Technical Field

The present application relates to the field of woodworking machinery, and more particularly to an orientation control mechanism that limits unoriented planar motion to a range defined by the mechanism. In addition, the movement of the directional control mechanism can be monitored.

Background

Typical motion mechanisms are typically capable of only a single form of motion, such as translation or rotation. However, in practical applications, it is often desirable to be able to convert one form of motion into another, for example translation into rotation.

In woodworking machines, the shape lines of the wood are variable, and during the wood processing process, the mating parts of the processing machine need to move along the shape lines of the wood. During movement, the wood may touch the machine, thereby creating a non-directional force on the machine. The applicant believes that there is a need for an orientation adjustment mechanism that limits the non-directional forces generated by wood on a processing machine to a specified range and further converts this limited motion into directional rotation. The directional control mechanism can be installed in woodworking machinery and used as a component for detecting the shape lines of wood in the wood processing process.

Disclosure of Invention

The application aims to provide an orientation regulating mechanism which limits unoriented plane movement to a range defined by the mechanism. The above purpose is achieved by the following technical scheme:

the directional regulation and control mechanism comprises a movement limiting seat, a movement regulating control piece and a movement triggering piece, wherein the movement limiting seat is provided with a limiting space, a first end of the movement regulating control piece is contained in the limiting space, a second end of the movement regulating control piece is fixed with the movement triggering piece, and the limiting space limits movement of the movement regulating control piece.

When the motion trigger piece is subjected to external force to generate non-directional motion on the plane, the second end of the motion control piece is relatively fixed with the motion trigger piece, so that the motion control piece can generate non-directional motion on the plane. On the other hand, the first end of the motion control piece is accommodated in the limiting space of the motion limiting seat, and the first end and the limiting space form clearance fit, so that the motion control piece can move in a limited mode in the range of the limiting space without any motion, and the purpose of limiting the motion of the motion control piece and the motion triggering piece is achieved. According to actual needs, the motion trigger piece can be a round rod, the motion limiting seat and the motion regulating piece are horizontally placed, and meanwhile the motion regulating piece and the round rod are mutually and vertically fixed, so that the round rod moves in the horizontal direction vertically all the time. In addition, the motion control piece and the motion trigger piece can be integrally formed and are constructed as mutually perpendicular integral parts, and the same technical effects can be exerted.

Preferably, the directional control mechanism of the application further comprises a motion limiting block, the upper surface of the motion limiting seat is provided with a groove, and the lower surface of the motion limiting block covers the groove to form the limiting space. According to actual needs, the groove can be a semi-open U-shaped groove or a groove penetrating through the upper surface of the motion limiting seat. When the lower surface of the motion limiting block covers the groove, the formed limiting space is in a channel shape, and the motion control piece moves in the channel in a limited way.

Preferably, the first end of the motion control piece is provided with a first cylinder protruding upwards, the motion limiting block is provided with a first circular through hole, the first cylinder penetrates through the first circular through hole, and the first circular through hole and the groove jointly form the limiting space. According to actual needs, a certain clearance distance exists between the first cylinder and the first circular through hole, and the clearance distance provides free movement space for the first cylinder (namely the motion control part), namely, the first circular through hole plays a limiting role of maximum displacement for the motion control part. The movement of the movement adjustment member will be limited to the first circular through hole and will only move within the range defined by the first circular through hole. Therefore, no matter which direction the motion trigger piece moves to under the action of external force, the movement range of the motion control piece is limited because the motion control piece is limited by the first circular through hole.

Preferably, the orientation adjusting mechanism further comprises a corner piece and a plurality of tensioning arms, the movement limiting block is provided with a concave part coaxial with the first circular through hole, the plurality of tensioning arms are uniformly arranged in the concave part along the circumferential direction of the first circular through hole, and at least one tensioning arm is abutted against the side face of the first cylinder; each tensioning arm is provided with an upper convex cylinder and a lower convex cylinder, the concave part is provided with a round hole corresponding to the lower convex cylinder, the swinging angle piece is provided with a long groove extending along the radial direction of the first round through hole and corresponding to the upper convex cylinder, the lower convex cylinder is inserted into the round hole, and the upper convex cylinder is inserted into the long groove.

In the directional control mechanism of the present application, the tensioning arm and the pivot angle are linked. Specifically, when the movement trigger is not subjected to external force, the at least one tensioning arm abuts against the side face of the first cylinder penetrating through the first circular through hole. According to actual needs, the tensioning arms are evenly arranged around the circumference of the first cylinder, and each tensioning arm may be arranged to abut the side of the first cylinder such that the first cylinder is coaxial with the first circular through hole. At this time, the upper convex cylinder of each tensioning arm is positioned at one end of the swing angle piece long groove close to the center of the circle. At this time, it is called an initial state.

When the motion trigger piece is acted by external force to move in any direction on the plane, at least one of the tensioning arms which is originally in contact with the first cylinder is driven, so that the tensioning arm swings around the center of the lower convex cylinder. At the same time, the upper convex cylinder of the tensioning arm moves along with the upper convex cylinder, thereby driving the swinging angle piece to rotate. The balance tensioning arms are driven to swing through the swing angle piece, and the upper convex cylinder moves away from the circle center in the inner diameter of the long groove of the swing angle piece. The direction in which the tensioning arm is driven is fixed, so that the direction in which the swinging angle piece rotates is also fixed, thereby realizing the conversion of unoriented and irregular planar motion into regular and fixed-direction rotary motion. When the first cylinder is contacted with the wall of the first circular through hole, the movement of the movement regulating piece reaches the maximum displacement, at the moment, each tensioning arm swings to the maximum extent, and the upper convex cylinder radially moves to one end of the long groove far away from the circle center in the long groove, so that the swing angle piece rotates to the maximum angle. At this time, it is called a limit state.

Preferably, the directional control mechanism further comprises a covering part and a bearing, wherein the covering part is provided with a cavity, a second cylinder protruding downwards is arranged in the cavity, a second circular through hole is correspondingly formed in the swinging angle piece, the swinging angle piece is sleeved on the bearing through the second circular through hole, the bearing is arranged on the second cylinder, and the swinging angle piece is arranged in the cavity through the bearing and can rotate around the second cylinder. According to actual need, the second cylinder of the covering piece can be provided with a step, the second circular through hole of the corner fitting can also be provided with a step, and the bearing is in interference fit with the second cylinder. After the installation, the bearing is abutted against the step of the second cylinder and the step of the second circular through hole, so that the corner piece is prevented from sliding downwards and can rotate around the second cylinder.

Preferably, the swing angle member is provided with an initial swing angle position and a limit swing angle position, and the cavity is correspondingly provided with an initial detection switch and a limit detection switch, and the initial detection switch and the limit detection switch detect the movement of the swing angle member. In practical application, when the orientation regulating mechanism is in an initial state, the initial swing angle position of the swing angle piece is close to the initial detection switch, and the initial detection switch outputs an initial position signal; when the orientation regulating mechanism is in a limit state, the limit swing angle position of the swing angle piece is close to the limit detection switch, and the limit detection switch outputs a limit position signal; when the orientation regulating mechanism is between the initial state and the limit state, the swing angle piece is not close to the initial detection switch or the limit detection switch, and no signal is output. Through the arrangement, the motion state of the directional control mechanism can be monitored.

Preferably, the shape of the corner piece and the cavity are both in a convex shape, the initial swing angle position and the limit swing angle position are respectively positioned at the shoulder parts of the convex swing angle piece, and the initial detection switch and the limit detection switch are correspondingly arranged at the shoulder parts of the convex cavity respectively. The corner piece can rotate and swing in the cavity, and in the initial state, one shoulder of the convex corner piece can be arranged to be close to the corresponding shoulder of the convex cavity; in the limit state, the corner piece rotates around the second cylinder by a maximum angle, so that the other shoulder of the corner piece approaches the other shoulder of the corresponding cavity. According to actual needs, the swinging angle piece and the cavity can be in other shapes, such as L-shaped, concave-shaped and the like, so long as the detection switch can detect the movement state of the swinging angle piece.

Preferably, the orientation regulating mechanism of the present application further comprises a torsion spring, wherein the torsion spring is sleeved on the second cylinder, a first torsion arm of the torsion spring is abutted against the swinging angle piece, and a second torsion arm of the torsion spring is abutted against the cavity. The torsion spring is used for resetting the orientation regulating mechanism to an initial state. Specifically, when the movement triggering piece moves under the action of external force, the first cylinder of the movement adjusting piece moves within the range defined by the first circular through hole, the tensioning arm is driven to rotate the corner piece in the fixed direction, and at the moment, the torsion spring is compressed and deformed to store energy through the first torsion arm abutting against the corner piece. When the external force is eliminated, the torsion spring stretches to release energy storage and rebounds to reset to drive the corner piece and the tensioning arm to rotate, so that the first cylinder returns to an initial state coaxial with the first circular through hole, and the purpose of resetting the directional regulating mechanism is achieved.

Preferably, the motion control part is in a rod shape with a large middle part and small two ends, and the largest middle part is in an arc shape. Preferably, the rod-shaped movement control element can move in the limiting space when the movement triggering element moves. On the one hand, the first end of the motion control part can move along the length of the limiting space, on the other hand, the first end smaller than the middle part can move in the limiting space more flexibly, and can swing around the circle center of the middle maximum circular arc.

Preferably, the tensioning arm is arc-shaped, and the inner arc of the tensioning arm is abutted with the side face of the first cylinder. As a preferable scheme, the arc-shaped tensioning arm can be more beneficial to being matched with the arc-shaped side surface of the first cylinder, and the tensioning arm abutting against the side surface of the first cylinder can be pushed only by slightly deviating from the center of the first circular through hole as soon as the first cylinder moves, so that a subsequent series of linkage is completed.

The directional regulation mechanism has the following beneficial effects:

in the application, the movement adjusting control is arranged to conduct the unoriented plane movement of the movement triggering piece, and further, the plane movement is converted into the oriented rotation of the swinging angle piece through arranging the tension arm and the swinging angle piece which are mutually linked, and the movement triggering piece is reset through arranging the torsion spring. For the purpose of detecting and monitoring the directional control mechanism, a detection switch is also arranged for detecting the motion state of the directional control mechanism. The directional control mechanism can be applied to woodworking machinery and used as a component for detecting wood shape lines in the wood processing process. When the wood touches the motion trigger piece, the generated non-directional plane motion is converted into directional rotation in the mechanism, and a signal is output through the detection switch to obtain the motion state.

Detailed Description

The application will now be described in further detail with reference to the drawings and to specific examples.

As shown in fig. 1, 2 and 6, the directional control mechanism of the embodiment of the present application includes a movement trigger 19, a movement limit seat 22 of a movement control 18, a movement limit block 15 and a cover 10. The movement limiting seat 22, the movement limiting block 15 and the covering piece 10 are fixedly locked from bottom to top through the screw 20 and the gasket 21, specifically, the screw 20 penetrates through the hole 223 of the movement limiting seat and the hole 153 of the movement limiting block from bottom to top and finally penetrates into the screw hole 103 of the covering piece to be locked and fixed. In other embodiments, the connection and securement may also be by way of a non-threaded connection.

The movement triggering member 19 has a circular rod shape. In other embodiments, the motion trigger may also be a square bar. The second end of the movement control member 18 is provided with a hole 181, and the movement trigger member 19 is fixed to said hole 181 at the second end by means of a screw 16 and a washer 17. The upper surface of the motion limiting seat 22 is provided with a U-shaped groove 221, and the lower surface of the motion limiting seat covers the U-shaped groove 221 to form a channel with a rectangular longitudinal section. A first end of the motion control 18 is placed in the rectangular channel. The motion control piece 18 is in a rod shape with a large middle part and small two ends, wherein the largest middle part of the motion control piece is an arc 183, and the motion control piece 18 and the rectangular channel form clearance fit, so that the motion control piece 18 can move along the length of the U-shaped groove 221 or swing around the center of the largest arc 183 of the motion control piece. In other embodiments, the recess may extend through the upper surface of the motion limiter 22, rather than being U-shaped.

The first end of the motion control member 18 is provided with a first cylinder 182 protruding upwards, the motion limiting block 15 is provided with a first circular through hole 155, the first cylinder 182 penetrates through the first circular through hole 155, and the U-shaped groove 221 and the first circular through hole 155 jointly form a limiting space of the directional control mechanism of the embodiment. In this embodiment, the upper plane 184 of the first cylinder 182 is flush with the upper surface of the movement stopper 15. There is a certain clearance distance between the first circular through hole 155 and the first cylinder 182, and this distance provides a free displacement space for the motion control member 18, and is also a free displacement space of the motion trigger member 19, and the first circular through hole 155 plays a limiting role in maximum displacement for the motion control member 18.

The directional control mechanism of this embodiment also includes a corner piece 12 and a tensioning arm 14. The upper surface of the movement stopper 15 is provided with a recess 151 coaxial with the first circular through hole 155, and four circular arc-shaped tension arms 14 are uniformly arranged on the recess 151 in the circumferential direction of the first circular through hole 155. Each tensioning arm overlaps end to end and the number of tensioning arms may be two or more. In other embodiments, the tensioning arms may be non-arcuate, and correspondingly more tensioning arms may be required.

Each tensioning arm 14 is provided with an upper convex cylinder 141 and a lower convex cylinder 142. Circular holes 152 are uniformly arranged along the circumferential direction of the first circular through hole 155 on the concave portion 151, and the circular holes 152 correspond to the lower convex cylinder 142. The corner fitting 12 is provided with a long groove 123 extending in the radial direction of the first circular through hole 155 and corresponding to the upper convex cylinder 141, the lower convex cylinder 142 is inserted into the circular hole 155, and the upper convex cylinder 141 is inserted into the long groove 123.

It should be noted that the tensioning arm and the pivot angle are linked. When the movement trigger 19 is not subjected to an external force, the at least one tensioning arm 14 abuts against the side of the first cylinder 182 passing through the first circular through hole 155. In this embodiment, each tensioning arm 14 abuts the side of the first cylinder 182 such that the first cylinder 182 is coaxial with the first circular through hole 155. At this time, the upper convex cylinder 141 of each tensioning arm is located at one end of the long groove 123 of the corner fitting 12 near the center of the circle (as shown in fig. 5A and 7A). At this time, it is called an initial state.

When the movement trigger 19 is moved in any direction in a plane by an external force, at least one of the plurality of tensioning arms 14 originally abutting the first cylinder 182 is necessarily driven so that the tensioning arm swings around the center of its lower convex cylinder 142. At the same time, the upper projection 141 of the tensioning arm moves with it, thereby rotating the corner fitting 12. The rest of the tensioning arms are driven to swing by the swing angle 12 and the upper convex cylinder 141 is caused to move radially away from the center of the circle within the elongated slot 123 of the swing angle. The direction in which the tensioning arm is driven is fixed, so that the direction in which the swinging angle piece rotates is also fixed, thereby realizing the conversion of unoriented and irregular planar motion into regular and fixed-direction rotary motion. When the first cylinder 182 contacts the wall of the first circular through hole 155, the movement of the movement regulating member 18 reaches a maximum displacement, at which time each tensioning arm 14 swings a maximum extent, and the upper convex cylinder 141 moves within the inner diameter of the elongated slot 123 to an end of the elongated slot away from the center of the circle, such that the swing angle member rotates by a maximum angle α (as shown in fig. 5B and 7B). At this time, it is called a limit state.

As shown in fig. 1, 2, 3 and 6, a cover 10 is mounted above the movement limiting block 15, the cover 10 has a cavity, and the cavity and the swing angle member are both convex. A second cylinder 105 protruding downwards is arranged in the cavity, and the swinging angle piece 12 is provided with a second circular through hole 122. In this embodiment, the second cylinder 105 has a step 104, on which is an interference fit a bearing 13, the outer circumference of the bearing 13 being fitted with the pivot 12. The second circular through hole 122 has a step therein, and an end surface of the step abuts against an upper end surface of the bearing 13. Thus, the bearing 13 is mounted on the second cylinder 105, and the corner fitting 12 is placed in the cavity by the bearing 13 without slipping down and is rotatable about the second cylinder 105.

As shown in fig. 3, 7A and 7B, the corner piece 12 is provided with an initial swing angle position 124 and a limit swing angle position 125, respectively at the shoulders of the convex corner piece. The cavity of the cover 10 is correspondingly provided with an initial detection switch 23 and a limit detection switch 24, which are respectively inserted into the shoulders of the convex-shaped cavity. In the present embodiment, the initial detection switch 23 and the limit detection switch 24 extend from the outside of the cover 10, pass through the screw holes 102 and are fixed with nuts 26, 25, respectively, so that the ends of the initial detection switch 23 and the limit detection switch 24 extending into the cover are flush with the shoulder lateral line surfaces 106, 107 of the zigzag cavity. When the orientation regulating mechanism is in an initial state, the initial swing angle position 124 of the swing angle piece 12 approaches the initial detection switch 23, and the initial detection switch outputs an initial position signal; when the orientation regulating mechanism is in a limit state, the limit swing angle position 125 of the swing angle piece is close to the limit detection switch 24, and the limit detection switch outputs a limit position signal; when the orientation regulating mechanism is between the initial state and the limit state, the swing angle member is not close to the initial detection switch 23 or the limit detection switch 24, and no signal is output. Through the arrangement, the motion state of the directional control mechanism can be monitored.

In the present embodiment, the convex corner piece 12 is provided with a first abutment wall 121 at the neck and the convex cover cavity is provided with a second abutment wall 101 at the neck. The torsion spring 11 is sleeved on the second cylinder 105, specifically, above the bearing 13. The first torsion arm 111 of the torsion spring always abuts against the first abutment wall 121 of the pivot angle, and the second torsion arm 112 of the torsion spring always abuts against the second abutment wall 101 of the cavity. When the movement trigger piece 19 moves under the action of external force, the first cylinder 182 of the movement control piece 18 moves within the range defined by the first circular through hole 155, the tensioning arm 14 is driven to rotate the corner piece 12 in a fixed direction, and at this time, the torsion spring 11 is compressed and deformed to store energy by abutting against the first torsion arm 111 of the corner piece 12. When the external force is eliminated, the torsion spring 11 stretches to release energy storage and rebounds to reset to drive the corner piece 12 and the tensioning arm 14 to rotate, so that the first cylinder 182 returns to an initial state coaxial with the first circular through hole 155, and the purpose of resetting the directional control mechanism is achieved.

In practical application, the directional control mechanism can be applied to woodworking machinery and used as a component for detecting wood shape lines in the wood processing process. When the wood touches the motion trigger piece, the generated non-directional plane motion is converted into directional rotation in the mechanism, and a signal is output through the detection switch to obtain the motion state.
