Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber preforms, in particular to a pneumatic staggered needle punching device. Background Art

[0002] During the production process of carbon fiber preforms, the needle plates of each preform unit layer need to be staggered to achieve the purpose of staggered needling. The staggered needling of the preform can not only improve the appearance of the carbon fiber preform, but also improve the overall qualification rate and overall quality level of the product. However, the staggered needling of carbon fiber preforms on the market mostly uses servo or stepper motors in conjunction with screw linear guides to achieve the purpose of needle plate staggering. However, the above staggered needling mechanism not only has high material cost and slow staggering speed, but also requires PLC to control the servo motor, which further increases the difficulty of control and the energy consumption of the equipment. In order to solve the above problems, this patent designs a pneumatic staggered needling device, which can ensure that our needle plates can be quickly staggered during the needling process of the carbon fiber preform, and the overall staggered needling mechanism has a simple structure, is easy to control, and has low energy consumption.

DETAILED DESCRIPTION

[0032] In the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish between protective components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] Example 1:

[0034] Please refer to Figure 3 A pneumatic needle-staggering acupuncture device includes a pneumatic needle-staggering mechanism 4, the pneumatic needle-staggering mechanism 4 includes a needle plate fixing plate 18, a needle plate mounting seat 19 is slidably connected to the needle plate fixing plate 18, a needle plate 20 is provided on the needle plate mounting seat 19, an adsorption fixing part 24 is provided on the needle plate fixing plate 18, the adsorption fixing part 24 is used to fix the needle plate mounting seat 19, and cylinders 21 are provided at both ends of the needle plate fixing plate 18, and the cylinder 21 is used to drive the needle plate mounting seat 19 to move.

[0035] The working principle and beneficial effects of the above scheme are as follows:

[0036] After the needling of one unit layer of the carbon fiber preform is completed, the adsorption fixing part 24 in the pneumatic staggered needle mechanism 4 releases the restriction on the needle plate mounting seat 19, loosens the needle plate mounting seat 19, and makes the needle plate mounting seat 19 free in the needle plate fixing plate 18. At this time, the cylinder 21 on one side controls the cylinder 21 to extend outward through the cylinder solenoid valve, pushing the needle plate mounting seat 19 to the specified position, while the cylinder on the other side remains stationary. After reaching the specified position, the adsorption fixing part 24 is activated to adsorb the needle plate mounting seat 19 to prevent the needle plate mounting seat 19 from moving freely during the needling process.

[0037] Compared with the traditional method of using a motor and a screw linear guide to achieve needle plate staggering, the present application has a faster needle staggering speed, a simpler structure, convenient control, and low energy consumption.

[0038] Example 2:

[0039] Please refer to Figure 3-Figure 5 On the basis of Example 1, both ends of the needle plate fixing plate 18 are fixedly connected to the cylinder fixing block 22, and the cylinder 21 is fixedly connected to the cylinder fixing block 22;

[0040] The output end of the cylinder 21 is fixedly connected to a buffer block 23 , and the upper tangent line of the buffer block 23 is higher than the needle plate mounting seat 19 .

[0041] The buffer block 23 is made of nylon material.

[0042] The needle plate fixing plate 18 is fixedly connected to the adsorption member fixing plate 25 , and the adsorption fixing member 24 is fixedly connected to the adsorption member fixing plate 25 .

[0043] The needle plate fixing plate 18 is provided with a sliding groove, and the needle plate mounting seat 19 is slidably connected in the sliding groove of the needle plate fixing plate 18 .

[0044] The needle plate 20 is a segmented structure.

[0045] The adsorption fixing member 24 is preferably an electromagnet.

[0046] The working principle and beneficial effects of the above scheme are as follows:

[0047] The adsorption fixing member 24 is set as an electromagnet. The method of fixing the needle plate mounting seat 19 by energizing the electromagnet not only replaces the traditional butterfly bolt or hexagon socket bolt to fix the needle plate mounting seat 19, but also makes it easier to use PLC control. At the same time, it can offset the gap between the needle plate mounting seat 19 and the needle plate fixing plate 18, ensuring that after the needle is inserted, the resistance generated by the barb on the needle is offset when it is lifted, thereby ensuring the stability of the needle plate mounting seat 19 and improving the overall needling quality.

[0048] A nylon buffer block 23 is provided at the cylinder 21. When the cylinder 21 pushes the needle plate mounting seat 19, because the pushing speed of the cylinder 21 is fast, the cylinder guide rod and the needle plate mounting seat 19 are both made of steel. When the cylinder 21 is directly pushed, it will cause damage to the cylinder 21, shortening its service life and generating impact noise. Because the nylon buffer block 23 has a certain elasticity, when the nylon buffer block 23 is installed, it can effectively avoid damage to the cylinder 21, prolonging its service life and reducing noise generated by impact.

[0049] The needle plate fixing plate 18 is connected to the needle plate mounting seat 19 through a slide groove. When the needle plate mounting seat 19 needs to move freely in the needle plate fixing plate 18, it can move horizontally smoothly. At the same time, an electromagnet threading hole can be designed on the side of the needle plate fixing plate 18 to facilitate the installation of the electromagnet.

[0050] The upper tangent line of the nylon buffer block 23 is higher than the needle plate mounting seat 19. When the buffer block 23 hits the needle plate fixing plate 18, it pushes the needle plate mounting seat 19 to the appropriate position, preventing the needle plate mounting seat 19 from being pushed away from the specified position. At the same time, when the nylon buffer block 23 hits the needle plate mounting seat 19, the cylinder 21 still has a 1mm movement margin, preventing the cylinder 21 from always moving at full stroke and reducing the service life of the cylinder 21.

[0051] The segmented needle plates 20 can be replaced at will in terms of the number of needle plates 20 according to the needling requirements of the carbon fiber preform, thereby meeting the needling requirements of various types of products.

[0052] Example 3:

[0053] Please refer to Figure 1-Figure 2 On the basis of Example 1, the pneumatic needle-staggering mechanism 4 is driven by the needling lifting mechanism 2 and the cam reciprocating mechanism 3;

[0054] The acupuncture lifting mechanism 2 is arranged on the fixed plate 1, and the acupuncture lifting mechanism 2 drives the mounting plate 11 to move. The pneumatic needle-shifting mechanism 4 is slidably connected to the mounting plate 11. The cam reciprocating mechanism 3 is arranged on the mounting plate 11, and the output end of the cam reciprocating mechanism 3 is connected to the pneumatic needle-shifting mechanism 4.

[0055] The acupuncture lifting mechanism 2 includes a first adjustment driving member 5, which is arranged on the fixed plate 1, and the output end of the first adjustment driving member 5 is connected to the adjustment plate 8;

[0056] The adjustment plate 8 is fixedly connected to a first sliding rod 7 , the first sliding rod 7 is slidably connected to a fixed block 6 , and the fixed block 6 is fixedly connected to the fixed plate 1 ;

[0057] The adjustment plate 8 is provided with a second sliding rod 12, a slider 13 is slidably connected to the second sliding rod 12, and the mounting plate 11 is fixedly connected to the slider 13;

[0058] The adjustment plate 8 is provided with a second adjustment driving member 9 , an output end of the second adjustment driving member 9 is connected to a follower block 10 , and the follower block 10 is fixedly connected to a mounting plate 11 .

[0059] The first adjustment drive member 5 and the second adjustment drive member 9 can be any one of a cylinder, a motor-screw combination or a linear motor.

[0060] The working principle and beneficial effects of the above scheme are as follows:

[0061] After the needling of one unit layer of the carbon fiber preform is completed, the first adjustment drive member 5 drives the adjustment plate 8 to move, so that the needle plate 20 moves vertically and is lifted upward to a safe position to wait for the next needling cycle;

[0062] The second adjustment driving member 9 drives the mounting plate 11 to move, so that the needle plate 20 moves horizontally to adjust the position of the needle plate 20;

[0063] The arrangement of the fixed block 6 , the first sliding rod 7 , the second sliding rod 12 and the sliding block 13 can make the movement of the needle plate 20 more stable.

[0064] Example 4:

[0065] Please refer to Figure 1-Figure 2 On the basis of Example 1, the cam reciprocating mechanism 3 includes a cam 14, the cam 14 is rotatably connected to the mounting plate 11, the mounting plate 11 is provided with a rotating driving member 15, and the output end of the rotating driving member 15 is connected to the cam 14;

[0066] The cam 14 is provided with a cam-shaped sliding groove, in which a driving rod is slidably connected, and the driving rod is fixedly connected to the balance plate 16. A balance rod is symmetrically fixedly connected to the balance plate 16, and the balance rod passes through the limit block 17 and is fixedly connected to the pneumatic staggered needle mechanism 4, and the balance rod is slidably connected to the limit block 17.

[0067] The working principle and beneficial effects of the above scheme are as follows:

[0068] The rotating driving member 15 drives the cam 14 to rotate, and the acupuncture is completed by changing the position of the driving rod in the sliding groove on the cam 14 and then the height of the needle plate 20;

[0069] The arrangement of the balance bar and the limit block 17 limits the moving direction of the needle plate 20 , so that the needle plate 20 can only move in the vertical direction relative to the mounting plate 11 , thereby ensuring the stability of the needle plate 20 in acupuncture.

[0070] Example 5:

[0071] Please refer to Figure 6-Figure 7 On the basis of Example 3, the fixing plate 1 is fixedly connected to the device through a quick-connect assembly, and the quick-connect assembly includes two groups of connecting blocks 27, one group of connecting blocks 27 is fixedly connected to the device through a mounting fixture 26, and the other group of connecting blocks 27 is fixedly connected to the fixing plate 1 through another group of mounting fixtures 26;

[0072] The connection block 27 is provided with a positioning post 34 , and one side of the positioning post 34 is provided with a positioning hole capable of inserting the positioning post 34 , and the positioning hole is provided on the connection block 27 ;

[0073] One side of the connecting block 27 is fixedly connected to a clamping ear 30, and the other side of the connecting block 27 is fixedly connected to a mounting ear 28. A locking rod 31 is rotatably connected to the mounting ear 28, and a clamping rod 29 is rotatably connected to the locking rod 31. A locking hole 37 is provided at the end of the clamping rod 29, and the locking hole 37 can be locked with the clamping ear 30 on the other set of connecting blocks 27;

[0074] The clamping rod 29 is provided with a locking chuck 36 at the connection point of the locking rod 31;

[0075] The locking rod 31 is rotatably connected to a locking member 32, and the locking member 32 is provided with a locking tooth 35, which can be engaged with a locking chuck 36. The locking member 32 is provided with a locking tooth 35, and a spring 33 is provided between the side of the locking member 32 and the locking rod 31;

[0076] The locking rod 31 is provided with a limiting slot 38 , and the mounting ear 28 is provided with a limiting rod, which is slidably connected in the limiting slot 38 .

[0077] The working principle and beneficial effects of the above scheme are as follows:

[0078] When installing the fixing plate 1, the positioning post 34 on the fixing plate 1 is inserted into the positioning hole on the device, and the positioning post 34 on the device is inserted into the positioning hole on the fixing plate 1, and the locking member 32 is pressed to compress the spring 33 so that the locking tooth 35 and the locking chuck 36 are separated, and the locking rod 31 is rotated to make the locking hole 37 close to the ear 30 until the locking hole 37 is engaged with the ear 30, and the locking rod 31 is rotated to reset the locking rod 31, and the locking member 32 is loosened. Under the action of the spring 33, the locking tooth 35 is engaged with the locking chuck 36;

[0079] By locking the locking teeth 35 and the locking chuck 36, the movement of the locking rod 29 is restricted and the position of the locking rod 29 is fixed, so that the installation of the fixing plate 1 and the equipment is more secure, and the installation through the quick-insert assembly is faster and more efficient. When the components on the fixing plate 1 fail, it is easier to disassemble and maintain.
