In the prior art, the sleeve and the telescopic arm body should preferably have circular cross sections in order to achieve high mechanical precision fit of the sleeving mechanical structure. Because the circular cross-section facilitates high precision manufacturing of the mating parts by means of machining (turning, boring or deep hole machining etc.).
For non-circular sections, the processing difficulty of the closed inner cavity is high, the product precision is low, and high-precision matching cannot be realized, so that the closed inner cavity can be only applied to engineering mechanical equipment with low precision requirements, such as wheel cranes, overhead working trucks and the like.
With the development of robotics, there is an increasing demand for industrial robots of the type of mechanical arms for heavy loads. Since rectangular bending resistance is better than that of a cylinder, for a mechanical mechanism of a set having a telescopic function of a polygon such as a square, there is a need to improve the fitting accuracy thereof.

Detailed Description
The technical solutions of the present invention will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 8, one embodiment of the present invention provides a telescoping mechanism based on a floating slider support. The telescopic mechanism comprises: an outer sleeve 11 and an inner wall body 12, one end of the outer sleeve 11 being provided open, the inner wall body 12 being slidably connected within the outer sleeve 11 and being capable of extending or retracting the outer sleeve 11 from the open end of the outer sleeve 11.
In this embodiment, the outer sleeve 11 has a tubular structure with one end open, and the inner wall 12 is fitted into the outer sleeve 11. The cross-sectional shape of the inner wall body 12 is the same as that of the outer sleeve 11, and the cross-sectional area of the inner wall body 12 is smaller than that of the outer sleeve 11, so that after the inner wall body 12 is assembled into the outer sleeve 11, a gap is provided between the side surface of the inner wall body 12 and the inner wall of the corresponding outer sleeve 11, so that the subsequent first slider assembly 2 and second slider assembly 3 can be assembled in this gap.
In the present embodiment, after inner wall body 12 is assembled into outer sleeve 11, inner wall body 12 can slide within outer sleeve 11 so that inner wall body 12 can extend out of outer sleeve 11 from the open end of outer sleeve 11 or so that inner wall body 12 can retract into outer sleeve 11 from the open end of outer sleeve 11.
The telescopic machanism based on floating slider supports that this embodiment provided, telescopic machanism still includes: a first slider assembly 2 and a second slider assembly 3, both the first slider assembly 2 and the second slider assembly 3 being arranged within the outer sleeve 11. The first slider assembly 2 includes a fixed block 21 and a first slider 22, the fixed block being coupled to an inner wall of the outer sleeve 11. The fixed block 21 is provided with a first arc-shaped surface 211, the first floating block 22 is provided with a second arc-shaped surface 221 corresponding to the first arc-shaped surface 211, and the first floating block 22 is matched with the first arc-shaped surface 211 through the second arc-shaped surface 221 and is in sliding connection with the fixed block 21. Or; the fixed block 21 includes a base 212 and a roller 213 rotatably coupled to the base 212, and the first slider 22 is coupled to an edge of the roller 213 and is rotatable with the roller 213. The second slider assembly 3 includes a second slider 31, the second slider 31 being telescopically coupled to the inner wall of the outer sleeve 11. When the inner wall 12 has three sides, the three sides are all stress surfaces 121. When the inner wall body 12 has four or more side surfaces, all the side surfaces are divided into a stress surface 121 and a non-stress surface 122 along the bearing direction of the inner wall body 12. The bearing surface 121 and the non-bearing surface 122 are both provided with the slide ways. The bearing surface 121 has a floating area 123 capable of moving in a direction approaching to the inner wall of the outer sleeve 11, the first slider 22 is slidably connected to a portion of the slide rail located in the floating area 123, and the second slider 31 is slidably connected to the rest of the slide rail located in the bearing surface 121. When the inner wall 12 further has a non-stress surface 122, part of the second slider 31 is slidably connected to the rest of the slide way on the stress surface 121, and the rest of the second slider 31 is slidably connected to the slide way on the non-stress surface 122.
In this embodiment, the telescopic mechanism further includes a first slider assembly 2 and a second slider assembly 3, where the first slider assembly 2 and the second slider assembly 3 are both disposed in the outer sleeve 11, and one end of each of the first slider assembly 2 and the second slider assembly 3 is connected to the inner wall of the outer sleeve 11, and the other end abuts against the side surface of the inner wall 12 to support the inner wall 12. Wherein the first slider assembly 2 has a swinging function and the second slider assembly 3 has a telescoping function.
In the present embodiment, the first slider assembly 2 is composed of a fixed block 21 and a first slider 22, and the fixed block 21 is fixedly connected to the inner wall of the outer sleeve 11, alternatively, may be welded, may be bolted, or the like. The first slider 22 has one end connected to the fixed block 21 and the other end abutting against the side surface of the inner wall body 12. Since the first slider 22 can swing with respect to the fixed block 21, when the inner wall body 12 is inclined by a load, the first slider 22 swings under the action of the inner wall body 12, and the first slider 22 can always abut against the inner wall body 12.
The first slider 22 swings relative to the fixed block 21 in two embodiments, specifically as follows:
in the first embodiment, the fixing block 21 is provided with the first arc surface 211, the first slider 22 is provided with the second arc surface 221, and the first arc surface 211 corresponds to the second arc surface 221, that is, when the fixing block 21 and the first slider 22 are assembled together, the first arc surface 211 can be attached to the second arc surface 221, or the first arc surface 211 can be parallel to the second arc surface 221.
After the fixed block 21 and the first slider 22 are assembled together, the first slider 22 can slide along the first arcuate surface 211 under the cooperation of the first arcuate surface and the second arcuate surface 221.
When the inner wall 12 is loaded and inclined in the outer sleeve 11, the first slider 22 slides and inclines under the action of the two arc surfaces, and the first slider 22 can still be abutted against the side surface of the inner wall 12.
In the second embodiment, the fixed block 21 includes a base 212 and a roller 213 rotatably coupled to the base 212, and the first slider 22 is coupled to an edge, i.e., a rim, of the roller 213. The first slider 22 may be fixedly connected to the rim, such as by welding or bonding, or may be detachably connected, such as by clamping or bolting. The first slider 22 can swing under the roller 213.
When the inner wall 12 is loaded and inclined in the outer sleeve 11, the first slider 22 swings and inclines under the action of the roller 213, and the first slider 22 can still abut against the side surface of the inner wall 12.
In the present embodiment, the second slider assembly 3 includes the second slider 31, and one end of the second slider 31 is connected to the inner wall of the outer sleeve 11, and the other end abuts against the side face of the inner wall body 12. The second slider 31 is capable of expanding and contracting (moving in a direction approaching or separating from the inner wall body 12) on the inner wall of the outer sleeve 11 so that the second slider 31 can still abut against the side surface of the inner wall body 12 when the inner wall body 12 is inclined.
In the telescopic mechanism provided in this embodiment, the inner wall body 12 has a stress surface 121, and the stress surface 121 is a side surface capable of moving in a direction approaching or separating from the inner wall of the outer sleeve 11 when the inner wall body 12 receives a load.
When the telescopic mechanism is a triangular telescopic mechanism, the inner wall 12 has three sides, and the three sides are all stress surfaces 121. When the telescopic mechanism is a quadrangular telescopic mechanism, the inner wall body 12 has four side surfaces, and in this case, the upper and lower side surfaces of the inner wall body 12 are stress surfaces 121 and the left and right side surfaces are non-stress surfaces 122, taking an example in which one end of the inner wall body 12 receives a load in the vertical direction.
In use, the second slider assembly 3 is used for limiting because the non-stressed surface 122 is not inclined, and the first slider assembly 2 and the second slider assembly 3 are used for limiting because the stressed surface 121 is inclined.
In this embodiment, the bearing surface 121 and the non-bearing surface 122 are both provided with a slide way, and the slide way can be adapted to the first slider 22 and the second slider 31 at the same time, so as to facilitate the processing of the inner wall 12.
Alternatively, in this embodiment, the sliding groove is a sliding groove engraved on the stress surface 121 and the non-stress surface 122, one end of the first slider 22 away from the fixed block 21 is slidably connected to the sliding groove, and one end of the second slider 31 away from the inner wall of the outer sleeve 11 is slidably connected to the sliding groove.
That is, in the present embodiment, the first slider assembly 2 and the second slider assembly 3 can support the inner wall body 12 within the outer sleeve 11, and at the same time, the first slider assembly 2 and the second slider assembly 3 cooperate with the slide groove, so that the inner wall body 12 can be positioned, and the sliding accuracy of the inner wall body 12 can be improved.
Optionally, in this embodiment, the slide may also be a sliding rail or the like.
Since the triangle telescopic mechanism has fewer practical applications, the square telescopic mechanism is taken as an example in the subsequent embodiments of the application.
In this embodiment, the telescoping mechanism is square, i.e., the inner wall 12 and outer sleeve 11 are square in cross-sectional shape. If the inner wall 12 is configured to bear a vertically downward load during use, the upper and lower side surfaces of the inner wall 12 are stress surfaces 121, and the left and right side surfaces are non-stress surfaces 122.
In the stress surface 121, the front end region of the stress surface 121 located below and the rear end region of the stress surface 121 located above are both floating regions 123, since they move in a direction approaching the inner wall of the outer sleeve 11 when the inner wall 12 receives a load.
A plurality of second sliding block assemblies 3 are arranged on the left inner wall and the right inner wall of the outer sleeve 11, and the second sliding block assemblies 3 on the two inner walls are in one-to-one correspondence.
A plurality of first slider assemblies 2 are respectively provided at the front end of the upper inner wall and the rear end of the lower inner wall of the outer sleeve 11, a plurality of second slider assemblies 3 are provided at the remaining positions of the upper inner wall of the outer sleeve 11, and a plurality of second slider assemblies 3 are provided at the remaining positions of the lower inner side of the outer sleeve 11.
After assembly, the second slider 31 on the left and right inner walls of the outer sleeve 11 is slidably connected to the slide grooves on the left and right non-stress surfaces 122 of the inner wall body 12. The first slider 22 and the second slider 31 positioned at the rear end of the inner wall of the outer sleeve 11 are slidably connected to the slide grooves on the bearing surface 121 of the inner wall body 12. The first slider 22 and the second slider 31 positioned at the front end of the lower inner wall of the outer sleeve 11 are slidably connected to the slide grooves on the lower stress surface 121 of the inner wall body 12.
When the inner wall body 12 receives a vertically downward load, the rear end of the inner wall body 12 is slightly tilted, and at this time, the first slider 22 swings to be always slidably connected to the slide groove, and the second slider 31 is extended or retracted to be always slidably connected to the slide groove.
According to the telescopic mechanism provided by the embodiment, the first sliding block component 2 and the second sliding block component 3 in the outer sleeve 11 are matched with the sliding groove on the inner wall body 12, so that the inner wall body 12 can be supported and positioned, and the matching precision of the telescopic mechanism is improved. Moreover, since the first sliding block assembly 2 has the swinging function, and the second sliding block assembly 3 has the telescopic function, the inner wall body 12 always slides towards the ideal direction, and errors are eliminated.
