Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a narrow outward-turning forward moving component. Background Art

[0002] During the operation of mechanical equipment, forward movement is a common feed motion, typically achieved by a driver driving a movable part relative to a fixed part. During this forward movement, the movable part must be reliably supported by the fixed part to ensure stable movement, while also ensuring that the movable part is accurately guided by the fixed part to ensure precise movement.

[0003] This type of forward moving component commonly has the following structures: one is to set a guide rail-type guide on the fixed part, and the movable part is mounted on the guide part to ensure the movement accuracy, but this structure has high requirements for the guide part under some working conditions with load requirements, and the guide part has a short life; the other is to open a guide groove on the fixed part, and the movable part moves as a whole in the guide groove, but this structure makes the overall mechanism bulky and only suitable for use close to the ground; there is also a two opposite track grooves on the fixed part, and the two ends of the movable part move along the two track grooves, and the two track grooves support the ends of the movable part. In this structure, in order to ensure the supporting strength of the movable part, the spacing between the two track grooves is generally designed to be larger to match the size of the movable part, and the corresponding size of the fixed part is larger, so it is limited in use in some occasions with narrow space.

[0004] Therefore, it is necessary to develop a forward moving assembly with compact structure, good moving stability, high precision and strong carrying capacity. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0029] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0032] See also Figure 1 and Figure 2 As shown, this embodiment provides a narrow outward-turning forward moving assembly, including a forward moving track 1, a forward moving member 2 and a driving member 3, wherein:

[0033] The forward track 1 comprises two C-shaped channel steels 11 arranged in parallel, with the notches of the two C-shaped channel steels 11 facing outwards;

[0034] The forward moving member 2 is arranged above the forward moving track 1, and the two sides of the forward moving member 2 are provided with limiting parts 21 extending to the outside of the two C-shaped channel steels 11. The limiting parts 21 on each side are provided with limiting parts 4 that slide or roll with the corresponding notches of the C-shaped channel steel 11;

[0035] The driving member 3 is disposed on the forward track 1 , and a driving end of the driving member 3 is connected to the forward member 2 to drive the forward member 2 to move along the length direction of the C-shaped channel steel 11 .

[0036] Therefore, the structure in which the notches of the two C-shaped channel steels 11 face outward and cooperate with the forward moving member 2 on the outside is adopted, which not only accurately guides the forward moving member 2 but also forms a reliable support. Compared with the structure on the market with the notches facing inward, the spacing between the two C-shaped channel steels 11 can be reduced while ensuring that the forward moving member 2 is sufficiently stable, thereby effectively controlling the volume of the forward moving track 1, so that the narrow outward-flipping forward moving component can be applied to more occasions.

[0037] Optionally, the limit member 4 includes a roller bearing, the shaft of the roller bearing is installed on the limit member 21, the wheel of the roller bearing is embedded in the groove of the C-shaped channel steel 11 and rolls together, and at least two roller bearings are provided on the limit member 21 to ensure that the limit member 4 is only displaced along the length direction of the C-shaped channel steel 11 and to reduce movement wear.

[0038] In addition to the rolling fit of roller bearing parts and C-shaped channel steel 11, the limiter 4 can also adopt the sliding fit of slider parts and C-shaped channel steel 11 to meet the requirements of reducing wear and ensuring displacement accuracy. The specific form of the limiter 4 is not limited here.

[0039] Furthermore, a notch 12 is provided on the upper side edge of the end of the C-shaped channel steel 11. The notch 12 is used to facilitate the wheel portion of the roller bearing to enter and exit the notch of the C-shaped channel steel 11, thereby improving the convenience of installation and maintenance of the limit member 4. Moreover, since the notch 12 is located on the upper edge of the notch of the C-shaped channel steel 11, there is no need to worry about the wheel portion of the roller bearing falling out of the notch of the C-shaped channel steel 11 during operation.

[0040] Optionally, a stopper 13 for limiting the travel of the forward moving member 2 is provided on the C-shaped channel steel 11 to ensure that the forward moving member 2 moves within an appropriate travel range.

[0041] Optionally, the forward member 2 is provided with a plurality of reinforcing ribs 23 extending perpendicularly to the length of the C-channel steel 11, and a weight-reducing hole 24 is provided on the forward member 2 between two adjacent reinforcing ribs 23. Since the forward member 2 spans across two C-channel steels 11, the reinforcing ribs 23 can enhance the overall strength of the forward member 2, and the appropriate provision of the weight-reducing holes 24 can reduce the overall weight while maintaining structural strength.

[0042] Optionally, the driving member 3 includes a linear drive, a fixed base plate 14 is provided between the two C-shaped channel steels 11 , one end of the linear drive is connected to the fixed base plate 14 , and the other end of the linear drive is connected to the forward moving member 2 .

[0043] The linear actuator is preferably an electric push rod, and can also be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc., which can provide a driving force along the length direction of the C-shaped channel steel 11. The specific form of the linear actuator is not limited here.

[0044] In particular, in order to ensure that the forward rail 1 provides a certain degree of support for the forward member 2, the bottom surface of the forward member 2 can be in sliding contact with the upper edge of the C-shaped channel steel 11. Under the guidance of the limit member 4, the direct contact between the bottom surface of the forward member 2 and the upper edge of the C-shaped channel steel 11 is also beneficial to improving the load-bearing capacity of the forward member 2, but it is necessary to control the wear of the contact surface.

[0045] Alternatively, a linear guide rail arranged along the length of the C-shaped channel steel 11 is provided on the upper edge of the C-shaped channel steel 11, and a slider that cooperates with the linear guide rail is provided on the bottom surface of the forward moving member 2. The cooperation structure of the linear guide rail and the slider can increase the load-bearing capacity of the forward moving member 2 to a certain extent and reduce friction damage between the forward moving member 2 and the C-shaped channel steel 11.

[0046] Optionally, the forward moving member 2 is further provided with a mounting portion 22 for mounting an actuator. The structure of the mounting portion 22 is adapted to the specific actuator to meet installation requirements.

[0047] In this embodiment, two forward moving members 2 are provided on the forward moving track 1. The two forward moving members 2 are driven by a driving member 3 to move in the same direction or in the opposite direction respectively, so as to meet more forward moving requirements, such as two actuators moving independently, two actuators moving synchronously in the same direction, etc.

[0048] In summary, the narrow outward-turning forward moving component has a compact structure, precise and stable movements, strong load-bearing capacity, and effectively controlled volume, and can meet the requirements of various working conditions.

[0049] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
