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.

[0038] Large-span alignment mechanism is a necessary equipment for the production of steel mesh. Most of the existing large-span alignment mechanisms use double-cylinder driven alignment components to align multiple arranged steel bars. However, in actual use, there is always a sequence in the driving of the double cylinders, which leads to the problem of mechanism jamming in the process of aligning the steel bars, which has a potential adverse effect on the stability of the steel bar alignment line.

[0039] Analyzing the above problems, there is always a sequence in the driving of the dual cylinders and it is difficult to avoid it. Therefore, the main reason for the jamming of the large-span alignment mechanism is that the connection between the alignment components and the cylinder driving components is a rigid connection. A small amount of drive asynchrony will also produce harmful stress on the drive of the dual cylinders, causing the mechanism to jam or even damage the cylinder or other components. Therefore, it is possible to consider changing the rigid connection method between the alignment components and the cylinder driving components, and using a flexible connection method to reduce the impact of the dual cylinder drive asynchrony.

[0040] In view of this, the utility model proposes an alignment mechanism, and the parts to be aligned by the alignment mechanism can be cylindrical batteries, steel bars, or other products or structures that need to be aligned. The utility model does not limit the specific use of the alignment mechanism, but the alignment mechanism provided by the utility model can at least solve the problem of mechanism jamming caused by the asynchronous driving of the dual cylinders in the existing large-span alignment mechanism.

[0041] in, Figure 1 A structural schematic diagram of an embodiment of the aligning mechanism provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the cross-sectional structure of the center alignment mechanism along a first direction; Figure 3 for Figure 2 Schematic diagram of the enlarged structure of part A in the figure.

[0042] See also Figure 1 and Figure 2 In one embodiment of the utility model, the alignment mechanism 100 includes a mounting seat 1 and an alignment structure 3, the driving assembly 2 includes two alignment driving parts 21, the two alignment driving parts 21 are arranged at intervals in the first direction, and are movably arranged on the mounting seat 1 in the second direction, and the alignment structure 3 is extended along the first direction and arranged on the two alignment driving parts 21, wherein the alignment structure 3 can at least be deflected relative to the axis of the alignment driving part 21 in the third direction, and is movably arranged in the first direction.

[0043] It should be noted that the positions of the two aligning drive parts 21 on the aligning structure 3 can be in various situations, as long as they are arranged at intervals along the first direction and meet the requirements for applying the aligning force to the aligning structure 3, this embodiment does not limit it; the mounting seat 1 serves as the mounting base for the two aligning drive parts 21, and it can have multiple morphological structures. The aligning drive part 21 can be directly movably arranged on the mounting seat 1, and can also be indirectly movably arranged on the mounting seat 1 through other structures, this embodiment does not limit it; the function of the aligning drive part 21 is to provide a mounting base for the aligning structure 3 and drive the aligning structure 3 to move, it can be a single component, or it can be a part of a driving device, this embodiment does not limit it; the first direction, the second direction and the third direction are parameters of the aligning mechanism 100 itself Considering the direction, in one usage scenario, the first direction and the second direction are two mutually perpendicular directions in the horizontal plane, and the third direction is a vertical direction; the alignment structure 3 can at least be deflected relative to the axis of the alignment drive unit 21 in the third direction, so the stroke difference between the two alignment drive units 21 can be compensated by its own deflection, and the movement of the alignment structure 3 relative to the alignment drive unit 21 in the first direction enables the alignment structure 3 to adapt to the change of the straight-line distance between the two alignment drive units 21. There are many structural forms for realizing the above-mentioned action of the alignment structure 3. For example, a fisheye bearing is used to connect the alignment structure 3 and the alignment drive unit 21, the alignment structure 3 is arranged on the inner ring of the fisheye structure, and the outer ring of the fisheye structure is arranged on the alignment drive unit 21. The specific structural form is not limited to this embodiment.

[0044] In the technical solution of the utility model, the alignment structure 3 can move along the second direction under the driving action of two alignment drive parts 21, so as to complete the alignment operation of rows of steel bars, and the connection method between the alignment structure 3 and each alignment drive part 21 is not a rigid connection. During the asynchronous driving process of the two alignment drive parts 21, the alignment structure 3 can be appropriately deflected in the third direction axis, and can also move appropriately in the first direction, thereby achieving the effect of unloading force, avoiding the generation of harmful stress between the alignment structure 3 and the alignment drive part 21, alleviating the problem of mechanism jamming in the existing large-span alignment mechanism 100 during the alignment operation, and eliminating the adverse effects of the mechanism jamming on the alignment line.

[0045] In one embodiment, two aligning driving units 21 are respectively arranged at two ends of the aligning structure 3 along the first direction. According to the above technical solution, the aligning driving units 21 are arranged at two ends of the aligning structure 3 along the first reverse direction, so that a relatively balanced aligning force can be applied to the rows of steel bars through the aligning structure 3 to ensure the aligning flatness.

[0046] The alignment structure 3 proposed in the utility model can be set separately or on the conveyor line body. It can be understood that when the alignment structure 3 is set on the conveyor line body, online alignment operation can be realized, thereby ensuring the alignment efficiency. In view of this, in one embodiment, the driving assembly 2 also includes two lifting drive parts 22, which are arranged at intervals in the first direction and are movably arranged on the mounting seat 1 along the third direction; the two alignment drive parts 21 are respectively arranged in the corresponding lifting drive parts 22 and are movable along the second direction; the alignment structure 3 can be deflected relative to the axis of the alignment drive part 21 in the second direction.

[0047] It should be noted that when the alignment mechanism 100 is applied to the conveyor line, the conveyor line is usually placed along its own length direction and conveys the pieces to be aligned, so that multiple pieces to be aligned are arranged in the width direction of the conveyor line. In this embodiment, the first direction is the width direction of the conveyor line, and the second direction is the length direction of the conveyor line. The alignment structure 3 can be arranged above the conveyor line or below the conveyor line.

[0048] The lifting drive unit 22 can be directly movably arranged on the mounting seat 1, or can be indirectly movably arranged on the mounting seat 1 through other structures. This embodiment does not limit this, and "the alignment drive unit 21 is movably arranged on the two lifting drive units 22 along the second direction" can usually be understood as the alignment drive unit 21 is directly arranged on the lifting drive unit 22; based on the same principle as "the alignment structure 3 can at least be deflected relative to the axis of the alignment drive unit 21 in the third direction", the alignment structure 3 can be deflected relative to the axis of the alignment drive unit 21 in the second direction, so that the alignment structure 3 can also compensate for the stroke difference between the two lifting drive units 22 through its own deflection; generally speaking, a matching structure or another alignment structure 3 is usually arranged for the alignment structure 3 to correspond to it, so as to cooperate with the alignment structure 3 to align the parts to be aligned between the two.

[0049] According to the above technical scheme, through the appropriate setting of the mounting seat 1, the alignment structure 3 can be set across the conveyor line body, and through the activities of the two lifting drive parts 22, the alignment structure 3 can be driven to the top of the conveyor line body to intercept multiple pieces to be aligned therein, and the multiple pieces to be aligned are aligned in place under the activity of the alignment drive part 21. Finally, under the driving action of the lifting drive part 22, the alignment structure 3 leaves the conveyor line body to make way for the pieces to be aligned after alignment. In this way, online alignment operations are realized, and the alignment efficiency of the alignment mechanism 100 is ensured.

[0050] If there is a deviation in the installation position of the two lifting drive parts 22, installation errors will occur, which will cause the two alignment drive parts 21 to be unable to maintain flush movement and easily cause the mechanism to jam. In view of this, in another embodiment, the mounting base 1 includes a mounting beam 11 extending along the second direction, and the two lifting drive parts 22 are arranged on the mounting beam 11.

[0051] It should be noted that the installation beam 11 can generally be understood as a beam with a certain straightness.

[0052] According to the above technical solution, the two lifting drive parts 22 are installed on the same mounting beam 11. When the mounting base 1 is set as a whole, it can be ensured that the installation positions of the two lifting drive parts 22 will not have a large deviation. Even if a deviation occurs, it can be quickly adjusted, that is, the installation error of the alignment structure 3 can be reduced.

[0053] Specifically, in one embodiment, a first guide assembly 23 is provided between the lifting drive unit 22 and the mounting seat 1, and the first guide assembly 23 provides guidance for the movement of the lifting drive unit 22 in the third direction; and / or, a second guide assembly 24 is provided between the alignment drive unit 21 and the lifting drive unit 22, and the second guide assembly 24 provides guidance for the movement of the alignment drive unit 21 in the second direction.

[0054] It should be noted that the above two parallel technical features "a first guide assembly 23 is provided between the lifting drive part 22 and the mounting seat 1" and "a second guide assembly 24 is provided between the alignment drive part 21 and the lifting drive part 22" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better; the specific structure of the first guide assembly 23 and the second guide assembly 24 has various forms. For example, the first guide assembly 23 and the second guide assembly 24 can include linear guide rail assemblies at the same time, and can also include other sleeve guide rod guide assemblies, which are not limited in this embodiment.

[0055] According to the above technical solution, by setting the first guide component 23 and the second guide component 24, a guiding function can be provided for the activities of the lifting drive unit 22 and the alignment drive unit 21, thereby ensuring the consistency of the repeated activity paths of the lifting drive unit 22 and the alignment drive unit 21, and ensuring that the alignment accuracy of the alignment mechanism 100 meets the requirements after long-term use.

[0056] In one embodiment, the driving assembly 2 also includes a first driving device 25 and a second driving device 26. The first driving device 25 is arranged between the mounting base 1 and the lifting driving unit 22, and has a driving stroke along the third direction. The second driving device 26 is arranged between the lifting driving unit 22 and the alignment driving unit 21, and has a driving stroke along the second direction.

[0057] It should be noted that the first driving device 25 and the second driving device 26 include but are not limited to driving cylinders, and may also be driving structures such as linear driving modules and push rod motors, which are not limited in this embodiment.

[0058] According to the above technical solution, by setting the first driving device 25 and the second driving device 26, automatic alignment operation can be achieved under the control of the control system, thereby ensuring the alignment efficiency while reducing the manual labor intensity.

[0059] See also Figure 3 In one embodiment, the alignment driving unit 21 is formed with a mounting hole 211 extending through the first direction; the alignment structure 3 is penetrated through the mounting hole 211, and in the second direction, there is a movable gap 2111 between the hole wall of the mounting hole 211 and the alignment structure 3.

[0060] It should be noted that the existence of the movable gap 2111 not only allows the alignment structure 3 to move in the second direction, but also allows the alignment structure 3 to deflect in the third direction to a certain extent. It can be understood that the shorter the hole length of the mounting hole 211, the greater the deflection amplitude that the alignment structure 3 can make. The size of the movable gap 2111 can be in various situations. For example, it can take any value between 0.5 and 2.0 mm, as long as it can meet the requirement that the alignment structure 3 can make the above-mentioned activities.

[0061] According to the above technical solution, by setting the mounting hole 211 and designing the movable gap 2111 between the hole wall of the mounting hole 211 and the aligning structure 3, it is possible to use the simplest structure to complete the above-mentioned actions required by the aligning structure 3, thereby saving design and manufacturing costs.

[0062] For further information, see Figure 3 In one embodiment, the alignment driving unit 21 is formed with a mounting hole 211 extending along a first direction; the alignment structure 3 is penetrated through the mounting hole 211, and in the second direction and the third direction, there is a movable gap 2111 between the hole wall of the mounting hole 211 and the alignment structure 3.

[0063] It should be noted that the existence of the movable gap 2111 not only allows the alignment structure 3 to move in the second direction and the third direction, but also allows the alignment structure 3 to deflect along the axis in the second direction and the third direction to a certain extent. It can be understood that the shorter the length of the mounting hole 211, the greater the deflection amplitude that the alignment structure 3 can make. There are many possible sizes of the movable gap 2111, for example, it can take any value between 0.5 and 2.0 mm, as long as it can meet the requirement that the alignment structure 3 can make the above-mentioned activities.

[0064] According to the above technical solution, by setting the mounting hole 211 and designing the movable gap 2111 between the hole wall of the mounting hole 211 and the aligning structure 3, it is possible to use the simplest structure to complete the above-mentioned actions required by the aligning structure 3, thereby saving design and manufacturing costs.

[0065] Since the alignment structure 3 can move in the first direction relative to the alignment drive unit 21, there is a risk that the alignment structure 3 may be detached from the alignment drive unit 21 due to excessive movement. In view of this, in one embodiment, the alignment structure 3 has two plug-in sections 321 at both ends of the first direction, and an alignment section 311 between the two plug-in sections 321, and the plug-in sections 321 are inserted into the corresponding mounting holes 211; in the first direction, the cross-section of the alignment section 311 is larger than the cross-section of the mounting hole 211.

[0066] It should be noted that the function of the alignment section 311 is to directly contact the parts to be aligned so as to align them. The length of the alignment section 311 in the first direction should be smaller than the spacing between the two mounting holes 211 in the first direction, so as to ensure that the alignment structure 3 can move appropriately in the first direction.

[0067] According to the above technical solution, the plug-in section 321 and the alignment section 311 are integrally arranged, and the plug-in section 321 is inserted into the corresponding mounting hole 211, and the transverse surface of the alignment section 311 is larger than the transverse surface of the mounting hole 211, which makes it impossible for the alignment section 311 to be inserted into the mounting hole 211, that is, it cannot be detached from the mounting hole 211, thereby improving the safety of the alignment structure 3.

[0068] Specifically, see Figure 3 In one embodiment, the alignment structure 3 includes an alignment sleeve 31 and an insert cross bar 32, the insert cross bar 32 is passed through the alignment sleeve 31, and extends out of the alignment sleeve 31 at both ends in the first direction to form the insert section 321; the alignment sleeve 31 includes the alignment section 311.

[0069] The above technical scheme is a relatively simple design scheme for the alignment structure 3. The alignment sleeve 31 and the plug-in cross bar 32 are both components that are easily obtained in the workplace. The plug-in cross bar 32 and the alignment sleeve 31 can be fixed by welding or threaded connection. Compared with the alignment structure 3 machined out of the integral workpiece, the alignment structure 3 provided by the above technical scheme has lower manufacturing difficulty and production cost; not only that, by setting the plug-in cross bar 32, the structural strength of the alignment sleeve 31 can be enhanced to prevent it from being deformed after a long period of alignment operation.

[0070] The utility model also proposes a steel bar processing production line, which includes the straightening mechanism 100 of any one of the above-mentioned embodiments. The specific structure of the straightening mechanism 100 refers to the above-mentioned embodiments. Since the steel bar processing production line adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0071] Among them, the alignment mechanism 100 can be set up in only one group. By setting a matching structure relative to the alignment structure 3 in the second direction, the alignment structure 3 can push multiple steel bars to be aligned to the matching structure for alignment within its active stroke. The alignment mechanism 100 can also be set up in two groups. The two alignment structures 3 in the two groups of alignment mechanisms 100 are opposite to each other in the second direction, so as to cooperate within their respective active strokes to press the two ends of the multiple steel bars to be aligned together.

[0072] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
