Description

Technical Field

[0001] The utility model relates to the technical field of transmission connection components, in particular to a connection component. Background Art

[0002] Connecting components are often used for transmission in various mechanical devices. For example, in an annular guide rail conveying mechanism, adjacent sliders are connected by connecting components to form an annular conveying chain. One or more sliders are driven to move by a driving mechanism. The sliders are transmitted by connecting components to realize the movement of the entire annular conveying chain. The path of the annular guide rail conveying mechanism includes straight segments and arc segments. During the movement of the annular conveying chain, the spacing between the sliders will change to a certain extent. If the two ends of the fixed-length connecting component are respectively connected to a slider for rotation, a jam will occur when switching between the straight segment and the arc segment, affecting smooth movement. In the prior art, the two ends of the fixed-length connecting component are usually connected to the slider through an eccentric shaft, so that the eccentric rotation of the connecting component relative to the slider can adapt to the change in the slider spacing. However, in this way, the spacing between the sliders is in a free-changing state and cannot be automatically reset to the standard spacing state. An additional positioning mechanism is required to enable the slider to move at the standard spacing in the straight segment, and then accurately align with the offline equipment of each station for various processing, but it will lead to a complex overall structure and high cost. Utility Model Content

[0003] The technical problem to be solved and the technical task proposed by the utility model are to improve the existing technology and provide a connecting component to solve the problem that the existing connection structure is difficult to effectively adapt when there is a floating change in the spacing between the parts to be connected in the current technology.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A connecting member includes a connecting end 1 and a connecting end 2, wherein an elastically deformable telescopic portion is connected between the connecting end 1 and the connecting end 2, and the telescopic portion is in a corrugated shape. The connecting member described in the utility model has a simple and compact structure, and uses a corrugated structure to form an elastically deformable telescopic portion, so that the spacing between the connecting end 1 and the connecting end 2 of the connecting member can be elastically changed, and the requirement of floating change of the spacing between the components to be connected can be flexibly met. The corrugated telescopic portion has a compact structure and good stability, and can ensure the accuracy and stability of the telescopic activity while realizing elastic telescopic deformation, which is conducive to making the spacing between the components to be connected meet the requirements more accurately.

[0006] Furthermore, a guide mechanism for guiding in the direction of the line connecting the first and second connection ends is connected between the first and second connection ends, and the guide mechanism includes a guide rod and a guide hole, one of which is arranged on the first connection end, and the other is arranged on the second connection end, and the guide rod and the guide hole are in guiding and sliding cooperation. The guide mechanism plays a restraining and guiding role on the elastic deformation of the telescopic part, so that the elastic deformation of the telescopic part can be more stably along the direction of the line connecting the first and second connection ends, avoiding the relative twisting between the first and second connection ends, improving the connection stability, and improving the stability and accuracy of the spacing adjustment between the components to be connected.

[0007] Furthermore, the guide rod is provided with a limiting portion for limiting in the guiding sliding direction, so as to limit the telescopic range of the telescopic portion and better control the accuracy of the telescopic activity of the connecting member.

[0008] Furthermore, in a guiding direction perpendicular to the guiding mechanism, the telescopic parts are respectively provided on both sides of the guiding mechanism, so as to improve the reliability and stability of the telescopic activity of the connecting member.

[0009] Furthermore, it also includes a connecting middle end arranged between the connecting end 1 and the connecting end 2, a telescopic part is arranged between the connecting end 1 and the connecting middle end, and a telescopic part is arranged between the connecting middle end and the connecting end 2. Therefore, the connecting end 1 and the connecting middle end can independently perform telescopic activities, and the connecting middle end and the connecting end 2 can also independently perform telescopic activities, thereby realizing the telescopic activities between the connecting end 1 and the connecting end 2 as a whole, and realizing additional functions through the connecting middle end, for example, in the application of the ring conveyor chain, usually a power mechanism drives one or more sliders therein to move to realize the movement of the entire ring conveyor chain. When the connecting member described in the utility model is used to connect adjacent sliders, the power mechanism pushes the connecting middle end to move while pushing the slider to move, which can effectively improve the travel speed of the ring conveyor chain, improve the operation and conveying efficiency of the ring guide conveying mechanism, and thus improve production efficiency.

[0010] Furthermore, a guide mechanism for guiding in the direction of the connection line between the first connection end and the middle connection end is connected between the first connection end and the middle connection end, and a guide mechanism for guiding in the direction of the connection line between the middle connection end and the second connection end is connected between the middle connection end and the second connection end, and the guide mechanism includes a guide rod and a guide hole, and the guide rod and the guide hole are guided and slidably matched. The guide mechanism plays a restraining and guiding role on the elastic deformation of the telescopic part, so that the telescopic part can be telescoped along a preset direction, thereby enabling the connection end 1 and the middle connection end, and the connection middle end and the second connection end to accurately telescope.

[0011] Furthermore, the corrugated shape includes one or a combination of a rectangular wave shape, a triangular wave shape, a sine wave shape, and a U-shaped wave shape. The structure is easy to implement, has good stability, and can stably perform elastic deformation to achieve telescopic adjustment. Under the action of external force, the telescopic part of the corrugated shape undergoes elastic deformation in the wavelength direction to achieve telescopic activity, has good resilience, and high precision.

[0012] Furthermore, at least two groups of the telescopic parts are arranged side by side, thereby improving the reliability and stability of the telescopic activity of the connecting member.

[0013] Furthermore, the connecting member is an integral member and does not require assembly or disassembly, making it more convenient to use, having a compact structure, high strength, and good stability, and can ensure high precision and high stability while achieving telescopic activities.

[0014] Furthermore, the connecting member is cut, cast, or injection molded, and the specific manufacturing method is selected according to the required material of the connecting member. For example, when used in a ring guide rail conveying mechanism, the connecting member is preferably made of metal. The prefabricated block-shaped metal parts can be processed into an integrated connecting member by wire cutting or laser cutting. The processed connecting member has good integrity, high integration, high structural strength, good stability, high dimensional accuracy, can realize long-term and stable telescopic activities, can withstand high load forces, has a long service life, and can reduce maintenance frequency and costs.

[0015] Furthermore, the connecting member is wrapped and connected with a jacket layer covering the telescopic part. Since the telescopic part is in a corrugated shape, that is, the telescopic part is a reciprocating bending structure, it has a bending gap. During use, foreign matter may enter the bending gap, thereby affecting the elastic deformation of the telescopic part, that is, affecting the normal telescopic activity of the connecting member. The telescopic part is covered by the jacket layer without affecting the elastic deformation of the telescopic part. The jacket layer can effectively prevent foreign matter from entering the bending gap, thereby ensuring that the connecting member can perform telescopic activities in a long-term and stable manner.

[0016] Furthermore, the telescopic part is filled with a filler of a flexible material, and the connecting member is wrapped and connected with a jacket layer that covers the telescopic part and the filler. The filler is used to fill the bending gap of the telescopic part, which better prevents foreign matter from entering the bending gap or accumulating dust, etc., and ensures that the connecting member can stably perform telescopic activities. The jacket layer wraps and protects the telescopic part and the filler, and prevents the filler from separating from the telescopic part, thereby better extending the service life.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] The connecting component described in the utility model has a simple and compact structure. It utilizes a corrugated structure to form an elastically deformable telescopic portion, so that the spacing between the connecting end one and the connecting end two can be adjusted. The corrugated telescopic portion has a compact structure and good stability. While realizing elastic telescopic deformation, it can also ensure the accuracy and stability of the telescopic activity, which is conducive to making the spacing between the parts to be connected more accurately meet the needs.

DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model discloses a connecting member which can be elastically deformed to adapt to the change in the spacing between the connected parts, can be accurately reset to ensure that there is a precise spacing between the connected parts, has a simple and compact structure, high strength and good stability.

[0030] like Figure 1 As shown, a connecting member mainly includes a connecting end 1 and a connecting end 2, wherein an elastically deformable telescopic portion 3 is connected between the connecting end 1 and the connecting end 2, and the telescopic portion 3 is in a corrugated shape. The structure is simple and compact, and the elastically deformable telescopic portion 3 is formed by a corrugated structure. One end of the telescopic portion 3 in the wavelength direction is connected to the connecting end 1, and the other end is connected to the connecting end 2. The telescopic portion 3 can realize the telescopic activity of the connecting member by elastic deformation in its wavelength direction, that is, to realize the change of the spacing between the connecting end 1 and the connecting end 2. After the connecting end 1 is connected to the first part to be connected, and the connecting end 2 is connected to the second part to be connected, the connecting member can perform telescopic activity with the change of the spacing between the first part to be connected and the second part to be connected, so as to maintain a reliable connection relationship between the first part to be connected and the second part to be connected, and can adapt to the change of the spacing while ensuring mutual transmission. The telescopic portion 3 with a corrugated shape has a compact structure and good stability. It can ensure the precision and stability of the telescopic activity while realizing elastic telescopic deformation, which is conducive to making the spacing between the parts to be connected more accurately meet the requirements.

[0031] The corrugated shape of the telescopic portion 3 specifically includes one or a combination of a rectangular wave shape, a triangular wave shape, a sine wave shape, and a U-shaped wave shape. The telescopic portion 3 with a corrugated shape is a structure that bends back and forth along the wavelength extension direction. The reciprocating bending structure is equivalent to a plurality of elastic cantilevers connected in sequence. The elastic cantilevers can realize the telescopic movement of the connecting component by elastic deformation. The bending angles of the rectangular wave shape and the triangular wave shape are large and there is no transition area. The sine wave shape and the U-shaped wave shape have a smooth transition area. Therefore, relatively speaking, the stability of the rectangular wave shape and the triangular wave shape is weaker than that of the sine wave shape and the U-shaped wave shape. Therefore, it is preferred to use the sine wave shape and the U-shaped wave shape. The U-shaped wave shape is as follows: Figure 1 As shown, the corrugated shape of the telescopic part 3 includes a U-shaped bending part. Specifically, in the natural state, the U-shaped bending part includes two parallel straight cantilever sections and an arc section connected between the two cantilever sections, so as to achieve a smooth transition, high structural strength and stability, good stability while achieving elastic deformation, and a long service life. The wavelength, amplitude, wall thickness, and overall length of the corrugated telescopic part 3 in the wavelength direction are set according to specific needs, so that the elastic coefficient of the connecting member and the telescopic activity stroke can flexibly meet different needs. Figure 1In one embodiment shown, the telescopic parts 3 are provided with two groups of telescopic parts 3 side by side, and the two groups of telescopic parts 3 are elastically telescopically deformed synchronously, which can improve the reliability and stability of the telescopic activity of the connecting component.

[0032] In some application scenarios, it is preferred that the connecting member only needs to perform telescopic activities in the direction of the line connecting the connecting end 1 and the connecting end 2, that is, the corrugated telescopic portion 3 only performs telescopic deformation activities in the direction of its wavelength, but the elastic deformation direction of the corrugated telescopic portion 3 is not only in the wavelength direction, for example, it can also be in the amplitude direction, that is, there will be relative yaw and torsion activities between the connecting end 1 and the connecting end 2, and thus the connecting member as a whole is not linearly telescopic, and there will be a certain degree of twisting. Therefore, if Figure 2 As shown, in a preferred embodiment, a guide mechanism 4 for guiding in the direction of the line connecting the connection end 1 and the connection end 2 is connected between the connection end 1 and the connection end 2, and the guide mechanism 4 includes a guide rod 41 and a guide hole 42, and the guide rod 41 and the guide hole 42 are in guiding and sliding cooperation. Specifically, the guide hole 42 is set on one of the connection end 1 and the connection end 2, and the guide rod 41 is set on the other. The guiding sliding direction of the guide rod 41 and the guide hole 42 is along the wavelength extension direction of the corrugated telescopic part 3, so that the connection end 1 and the connection end 2 can only accurately telescope relative to each other along a straight line. Furthermore, in some application scenarios, there are precise restrictions on the telescopic stroke of the connecting member, and the connecting member needs to be telescopic within a limited range. Therefore, preferably, a limiting portion 43 for limiting in the guide sliding direction is provided on the guide rod 41 to limit the relative sliding stroke between the guide rod 41 and the guide hole 42, that is, to limit the elastic deformation amplitude of the telescopic portion 3. The limiting portion 43 may include one or both of a limiting portion for limiting the upper limit of the extension and a limiting portion for limiting the lower limit of the shortening. Figure 2 In one embodiment shown, the guide rod 41 on the connecting end 2 is generally a T-shaped rod structure, the head of the T-shaped rod is the limiting portion 43, a T-shaped slot is provided on the connecting end 1, the mouth of the T-shaped slot is the guide hole 42, the head of the T-shaped rod is inserted into the T-shaped slot, when the connecting member is extended, the limiting portion 43 abuts against the step at the guide hole 42 to achieve limiting, when the connecting member is compressed, the limiting portion 43 abuts against the bottom of the T-shaped slot to achieve limiting. Figure 2 In one embodiment shown, the telescopic parts 3 are respectively provided on both sides of the guide mechanism 4 in a guide direction perpendicular to the guide mechanism 4, and the telescopic parts 3 on both sides are elastically deformed synchronously to improve the reliability and stability of the telescopic activity of the connecting component.

[0033] The elastically deformable telescopic part 3 used in the above-mentioned connecting member is in a corrugated shape. The telescopic part 3 can be elastically compressed and elastically stretched, that is, the connecting member can achieve elastic shortening and elastic elongation, and can be elastically automatically reset in both cases of elastic shortening and elastic elongation, that is, the corrugated telescopic part 3 can achieve bidirectional elastic reset, with high reset accuracy. Compared with the use of springs to achieve elastic expansion and contraction, the structure is more compact, stable and accurate. The traditional telescopic structure formed by using springs can usually only be reset in one direction. The spring is either a compression spring or a tension spring. It can only be elastically reset after compression or tension, and cannot achieve both elastic reset after compression and elastic reset after tension. For example, a conventional telescopic sleeve structure includes an outer tube, an inner tube and a spring. The inner tube is slidably sleeved in the outer tube, and a spring is arranged between the outer tube and the inner tube. This structure can only achieve elastic reset after elastic compression, but cannot achieve elastic reset after tension. If it is necessary to achieve elastic reset after compression and elastic reset after stretching, it is usually necessary to set up multiple springs for cooperation, and different springs respectively realize the elastic reset function in different directions, so that the structure is relatively complex, occupies a large volume, requires assembly of multiple parts, and has low precision.

[0034] like Figure 3 In one embodiment shown, the connecting member also includes a connecting middle end 5 arranged between the connecting end 1 and the connecting end 2, a corrugated telescopic portion 3 is connected between the connecting end 1 and the connecting middle end 5, and a corrugated telescopic portion 3 is connected between the connecting middle end 5 and the connecting end 2. Further, a guiding mechanism 4 for guiding in the direction of the connection line between the connecting end 1 and the connecting middle end 5 is connected between the connecting end 1 and the connecting middle end 5, and a guiding mechanism 4 for guiding in the direction of the connection line between the connecting middle end 5 and the connecting end 2 is connected between the connecting middle end 5 and the connecting end 2. The guiding mechanism 4 It includes a guide rod 41 and a guide hole 42, and the guide rod 41 and the guide hole 42 are matched for guiding sliding. Similarly, a limiting portion 43 is provided on the guide rod 41 for limiting the guide sliding direction, so as to limit the relative sliding stroke between the guide rod 41 and the guide hole 42. Preferably, the connection end 1, the connection middle end 5 and the connection end 2 2 are in a straight line, so that the linear telescopic activity of the connection end 1 relative to the connection middle end 5 is actually the linear telescopic activity of the connection end 1 relative to the connection end 2 2, and at the same time, the linear telescopic activity of the connection end 2 2 relative to the connection middle end 5 is actually the linear telescopic activity of the connection end 2 2 relative to the connection end 1 1.

[0035] The aforementioned connecting member can be applied to the circular guide rail conveying mechanism, that is, Figure 6 and Figure 7As shown, adjacent sliders 20 in the annular guide rail conveying mechanism are connected through a connecting member 10 to form an annular conveying chain. Specifically, a connecting end 1 of the connecting member 10 is rotatably connected to the previous slider 20, and a connecting end 2 of the connecting member 10 is rotatably connected to the subsequent slider 20. A driving portion 21 cooperating with the driving mechanism is provided on the slider 20, and a driving portion 2 11 cooperating with the driving mechanism is provided on the connecting middle end 5 of the connecting member 10. The driving portion 1 21 and the driving portion 2 11 are preferably rollers. The driving mechanism simultaneously drives the driving portion 1 21 on the slider 20 and the driving portion 2 11 on the connecting member 10 to make the annular conveying chain move. In a preferred embodiment, the driving mechanism can be a rotating driving wheel at the arc section of the guide rail of the annular guide rail conveying mechanism, and a driving arm is provided on the rotating driving wheel, which cooperates with the driving part 1 21 and the driving part 2 11 respectively. When the rotating driving wheel rotates, it pushes the annular conveying chain to move in a circular motion. By driving the slider 20 and the connecting member 10 at the same time, the slider 20 can pass through the arc section of the guide rail more smoothly and quickly, thereby improving the travel speed, that is, improving the conveying efficiency. Compared with the method of only driving the slider 20 to move, the driving mechanism and the annular conveying chain have more and more uniform matching parts, which can reduce the load borne by a single matching part, thereby improving the operating speed while reducing mechanical losses and extending the service life of the equipment.

[0036] like Figures 1 to 3 As shown, preferably, the connecting member is an integral member, that is, the connecting member itself is an integral and inseparable component, and its components are not connected by assembly, so that the structure is compact, strong, and stable, and there is no need for assembly and disassembly, so it is more convenient to use, and can ensure high precision and high stability while realizing telescopic activities. More specifically, the connecting member is cut, cast, or injection molded, and the specific manufacturing method is selected according to the material required for the connecting member. If plastic material is required, it is made by injection molding, and if metal material is required, it can be made by casting or cutting. Casting includes casting, die casting, etc., and cutting includes wire cutting, laser cutting, and other processing methods. When cutting, a high-strength metal block can be used to ensure the overall structural strength and stability of the connecting member, which can bear high-load external forces, and thus can perform stable and accurate transmission.

[0037] Figure 4In one embodiment shown, the connecting member is wrapped with a jacket layer 6 covering the telescopic portion 3, and the jacket layer 6 plays a role in protecting the connecting member and extending the service life. The telescopic portion 3 on the connecting member is in a corrugated shape, so that the telescopic portion 3 has a bending gap. During use, foreign matter may enter the bending gap, thereby affecting the elastic deformation of the telescopic portion 3, that is, affecting the normal telescopic activity of the connecting member. Therefore, the jacket layer 6 is provided to cover the telescopic portion 3 to effectively prevent foreign matter from entering the bending gap or dust from accumulating in the bending gap, so as to ensure that the connecting member can perform telescopic activities in a long-term and stable manner. Specifically, the jacket layer 6 can be fixedly connected to the connecting middle end 5, and the two ends of the jacket layer 6 are respectively provided with openings that expose the connecting end 1 and the connecting end 2. Preferably, the opening is an oblong hole along the telescopic direction of the connecting member, so as not to hinder the telescopic activity of the connecting member. Of course, the opening can be a hole with a larger diameter, as long as it does not hinder the connecting end 1 and the connecting end 2 from connecting to the outside and performing telescopic activities. In addition, the outer jacket layer 6 may be fixedly connected to the connection end 1, and an opening is provided on the outer jacket layer 6 to expose the connection middle end 5 and the connection end 2. Figure 1 and Figure 2 For the connecting member without a connecting middle end shown, the outer jacket layer 6 can be fixedly connected to the connecting end 1, and an opening can be provided on the outer jacket layer 6 to expose the connecting end 2. In addition, the outer jacket layer 6 can be fixedly connected to the connecting middle end 5, and the outer jacket layer 6 only covers the area where the telescopic part 3 is located but does not cover the entire length of the connecting member.

[0038] like Figure 5 In one embodiment shown, the telescopic part 3 is filled with a filler 7 made of a flexible material, and the filler 7 is used to fill the bending gap of the telescopic part 3, and then a jacket layer 6 that connects and covers the telescopic part 3 and the filler 7 is wrapped on the connecting component. The filler 7 made of a flexible material effectively fills the bending gap of the telescopic part 3, thereby more effectively preventing foreign matter from entering the bending gap of the telescopic part 3, and the filler 7 made of a flexible material can elastically deform with the telescopic part 3 and will not hinder the elastic deformation of the telescopic part 3, thereby ensuring that the connecting component can reliably perform telescopic activities, and the jacket layer 6 wraps and protects the telescopic part 3 and the filler 7, thereby preventing the filler 7 from separating and falling off from the telescopic part 3, thereby better extending the service life.

[0039] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
