Description

Technical Field

[0001] The utility model relates to the technical field of aluminum honeycomb profile processing, in particular to an aluminum honeycomb stacking block stretching mechanism. Background Art

[0002] Aluminum honeycomb blocks are a form of supply of aluminum honeycomb core materials, mainly used for subsequent processing into aluminum honeycomb composite materials. Before being further processed, aluminum honeycomb blocks maintain the shape of raw materials, which is convenient for storage and transportation. To process the blocks into aluminum honeycomb core materials, the blocks need to be stretched, and the blocks form a honeycomb hexagonal shape during the stretching process. At present, the stretching process in the aluminum honeycomb production process is completed by an aluminum honeycomb stretching machine, and the positioning of the aluminum honeycomb blocks on the aluminum honeycomb stretching machine is completed by a clamping and threading mechanism. The process is to manually place the aluminum honeycomb blocks to be produced on the clamping and threading mechanism of the aluminum honeycomb stretching machine and adjust the position, then insert the pin into the aluminum honeycomb blocks, and manually start the stretching equipment after the pin is clamped to operate.

[0003] The positioning and insertion of aluminum honeycomb blocks are done manually. Since the insertion position is not fixed each time, it is easy to cause excessive insertion of materials, waste of materials or unqualified stretching. In the process of loading and unloading materials, the edges of the aluminum honeycomb blocks are sharp, which can easily cause scratches and cuts. During the needle threading and clamping process of the aluminum honeycomb blocks, the operator needs to insert the insertion needle while positioning the blocks, and multiple insertion needles need to be inserted in sequence. This process requires two operators to work together at the same time, which is time-consuming and has low production efficiency. Utility Model Content

[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] The utility model provides an aluminum honeycomb stack stretching mechanism, such as Figures 1 to 6As shown, it includes: at least two pin mechanisms 100, the pin mechanism 100 includes at least two pin units 110, the pin unit 110 includes a pin 111, a guide mechanism 112, a positioning mechanism 113 and a support plate 114, the support plate 114 is used to support the bottom surface of the aluminum honeycomb stack, the positioning mechanism 113 is used to position the side of the aluminum honeycomb stack, the pin 111 is connected to the guide mechanism 112, the pin mechanism 100 also includes at least one driving mechanism 120, the driving mechanism 120 drives the pin 111 in the pin unit 110 to penetrate into the aluminum honeycomb stack or detach from the aluminum honeycomb stack, the pin mechanism 100 also includes a dispersion mechanism 130, the dispersion mechanism 130 drives the pin unit 110 to move along the second direction; at least one of the at least two pin mechanisms 100 is also provided with a moving mechanism 200, the moving mechanism 200 drives the pin mechanism 100 to move along the first direction; the first direction is the stretching direction of the aluminum honeycomb stack, and the second direction is perpendicular to the first direction.

[0034] The aluminum honeycomb stack stretching mechanism provided by the utility model comprises at least two pin insertion mechanisms 100 respectively performing pin insertion 111 operations on both ends of the aluminum honeycomb stack, at least one pin insertion mechanism 100 stretches the aluminum honeycomb stack through a moving mechanism 200, a positioning mechanism 113 and a support plate 114 in the pin insertion unit 110 can automatically complete the positioning of the aluminum honeycomb stack, a driving mechanism 120 and a guiding mechanism 112 in the pin insertion unit 110 can automatically insert the pins 111 into the aluminum honeycomb stack, and a dispersion mechanism 130 in the pin insertion mechanism 100 can make the pin insertion units 110 evenly distributed along the width direction of the aluminum honeycomb stack, so that the aluminum honeycomb stack is evenly stressed during the stretching process, thereby avoiding deformation of the aluminum honeycomb stack during stretching.

[0035] Before stretching the aluminum honeycomb blocks, the aluminum honeycomb blocks are first placed on the support plates 114 of the two pin insertion mechanisms 100. The loading process can be performed manually or by a robot. The use of a robot to load the blocks can prevent personnel from being scratched by the edges of the blocks when carrying the aluminum honeycomb blocks.

[0036] At least one of the two pin mechanisms 100 is provided with a moving mechanism 200, and the moving mechanism 200 can drive the pin mechanism 100 to move along the negative direction of the first direction after the loading is completed. The negative direction of the first direction is the opposite direction of the stretching direction of the aluminum honeycomb stack. At this time, the positioning mechanism 113 in the pin unit 110 can position the aluminum honeycomb stack. The positioning mechanisms 113 in at least two pin mechanisms 100 cooperate to complete the positioning of the aluminum honeycomb stack from both sides. Therefore, when placing the aluminum honeycomb stack on the support plate 114, it is not necessary to accurately position the aluminum honeycomb stack, and the requirements for the robot and manual loading are relatively low.

[0037] At least two pin insertion units 110 in the pin insertion mechanism 100 are in a close-together state in an initial state, such as Figure 5 After positioning is completed, the dispersion mechanism 130 drives the pin unit 110 to move along the second direction, so that the pin unit 110 is dispersed in the second direction, so that the pin unit 110 is evenly distributed along the width direction of the aluminum honeycomb stack, and is in a dispersed state, as shown in FIG. Figure 6 As shown, the aluminum honeycomb stack is subjected to uniform force during the stretching process, thereby avoiding deformation of the aluminum honeycomb stack during stretching.

[0038] Afterwards, the driving mechanism 120 drives the pin 111 to insert the pin 111 into the aluminum honeycomb block, and then the moving mechanism 200 is started to drive the pin mechanism 100 to move along the positive direction of the first direction, which is the stretching direction of the aluminum honeycomb block, to complete the stretching of the aluminum honeycomb block. During the stretching process, the honeycomb shape in the aluminum honeycomb block is gradually formed.

[0039] At least two pin mechanisms 100 are respectively located at two ends of the aluminum honeycomb stack, and the two ends of the aluminum honeycomb stack refer to the two ends that can be stretched to form a honeycomb. At least one pin mechanism 100 is provided at each end of the aluminum honeycomb stack.

[0040] In an optional embodiment, only one of the two pin insertion mechanisms 100 may be provided with a moving mechanism 200, and the other pin insertion mechanism 100 may be fixed.

[0041] In an optional embodiment, the two pin mechanisms 100 may both be provided with a moving mechanism 200, and the two pin mechanisms 100 move respectively in the positive and negative directions of the first direction to stretch the aluminum honeycomb stack.

[0042] In an optional embodiment, each pin unit 110 is provided with a driving mechanism 120 .

[0043] In an optional embodiment, one driving mechanism 120 can drive a plurality of pin units 110 simultaneously, including driving all the pin units 110 in one pin mechanism 100 simultaneously.

[0044] In an optional embodiment, the driving mechanism 120 may use a cylinder to drive the insertion pin 111, and the dispersion mechanism 130 may use a cylinder to move the insertion pin unit 110 along the second direction.

[0045] In an optional embodiment, if Figure 4 As shown, a limiting mechanism 140 is provided between at least two pin units 110 , and the limiting mechanism 140 limits the relative distance of at least two pin units 110 moving along the second direction.

[0046] In an optional embodiment, a plurality of pin units 110, at least three pin units 110, are provided in one pin mechanism 100, and a limiting mechanism 140 is provided between every two of the plurality of pin units 110. The dispersion mechanism 130 can drive only one pin unit 110, and the pin unit 110 drives the other pin units 110 to move along the second direction through the limiting mechanism 140. The limiting mechanism 140 limits the relative distance of the two pin units 110 moving along the second direction. The driven pin unit 110 can move along the second direction before moving to the limiting distance of the limiting mechanism 140. After moving to the limiting distance, the driven pin unit 110 can drive another pin unit 110 to move through the limiting mechanism 140.

[0047] In an optional embodiment, if Figure 4 As shown, the limiting mechanism 140 includes a limiting connector 141, the limiting connector 141 is provided with a limiting groove 142, one end of the limiting connector 141 is fixedly connected to one pin unit 110, the limiting connector 141 is movably connected to another pin unit 110 through the limiting groove 142, and the limiting groove 142 limits the range of movement of the limiting connector 141 and the pin unit 110. One end of the limiting connector 141 is fixedly connected to one pin unit 110, and can be fixedly connected by bolt connection, etc., the other end of the limiting connector 141 is provided with a limiting groove 142, and the other corresponding pin unit 110 can be provided with a protrusion that penetrates into the limiting groove 142, and the protrusion can move along the second direction in the limiting groove 142. The protrusion can be provided as a detachable bolt, screw, etc. The pin unit 110 can also be provided with a structure such as a slide groove that facilitates the relative movement of the limiting connector 141 and the pin unit 110.

[0048] In an optional embodiment, the dispersion mechanism 130 includes a driving state and a free state. When the dispersion mechanism 130 is in the driving state, the dispersion mechanism 130 drives the pin unit 110 to move along the second direction. When the dispersion mechanism 130 is in the free state, the dispersion mechanism 130 does not restrict the pin unit 110 from moving along the second direction.

[0049] In the driving state, the dispersion mechanism 130 drives the pin unit 110 to move along the second direction, so that the pin unit 110 is dispersed in the second direction, and then the pin unit 110 drives the pins 111 to insert into the aluminum honeycomb block, and the dispersion mechanism 130 is converted into a free state.

[0050] Since the aluminum honeycomb block is relatively dense and the honeycomb shape is not formed, after the dispersion mechanism 130 drives the pin unit 110 to complete the dispersion, it cannot ensure that the pin 111 is completely aligned with the honeycomb and the pin 111 can only be inserted into a smaller gap of the aluminum honeycomb block.

[0051] During the stretching process of the aluminum honeycomb stack, the honeycomb is gradually formed. At this time, the dispersion mechanism 130 is in a free state. The honeycomb forming process will pull the dispersed pin units 110 toward the middle. The dispersion mechanism 130 is in a free state and will not restrict the pin units 110. The dispersed pin units 110 can move toward the middle after being stressed. The honeycomb forming process will not be affected by the pin units 110, so that the aluminum honeycomb stack will not be deformed during the stretching process, thereby ensuring the honeycomb forming effect.

[0052] In an optional embodiment, if Figure 2 As shown, the dispersion mechanism 130 drives the pin unit 110 to move symmetrically along the positive direction and the negative direction of the second direction.

[0053] The dispersion mechanism 130 can be driven in two directions by two cylinders respectively, and the multiple pin units 110 are connected and limited by the limiting mechanism 140 to achieve uniform distribution of the multiple pin units 110. The pin units 110 are driven in the positive and negative directions of the second direction at the same time, so that the uniform distribution of the pin units 110 can be achieved more quickly.

[0054] In an optional embodiment, if Figure 2 As shown, the positioning mechanism 113 is arranged on the support plate 114. The support plate 114 supports the bottom surface of the aluminum honeycomb stack, and the positioning mechanism 113 is arranged on the support plate 114, which can conveniently play the role of positioning the side of the aluminum honeycomb stack, and can save the space of the pin unit 110. The positioning mechanism 113 can use one or more square blocks to position the side of the aluminum honeycomb stack.

[0055] In an optional embodiment, the positioning mechanism 113 is adjustably disposed on the support plate 114. The adjustable parts include the contact position between the positioning mechanism 113 and the aluminum honeycomb stack, or the positioning distance of the positioning mechanism 113 to the aluminum honeycomb stack, etc., which can be adjusted according to specific parameters such as the shape and size of the aluminum honeycomb stack, so that the pin unit 110 is suitable for more types of aluminum honeycomb stacks.

[0056] In an optional embodiment, the distance between the projection of the positioning mechanism 113 and the pin 111 along the first direction is not greater than 0.5 mm. The distance between the projection of the positioning mechanism 113 and the pin 111 along the first direction is the distance between the position where the pin 111 is inserted into the aluminum honeycomb block and the edge of the aluminum honeycomb block. 0.5 mm is about the thickness of about 10 aluminum plates. This distance can improve the utilization rate of the aluminum honeycomb block.

[0057] In an optional embodiment, the driving mechanism 120 drives the pin 111 to move a distance of not less than 60 mm, which is compatible with aluminum honeycomb blocks of various heights.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
