Description

Technical Field

[0001] The invention relates to the technical field of aviation composite knitted felt transfer processing, in particular to a knitted felt transfer tool. Background Art

[0002] Before the aviation composite knitted felt on the metal compartment of aviation equipment is equipped on the metal compartment, it is generally necessary to transfer the knitted felt to a simulated metal compartment mold of a specific size and shape. One is to check whether the size is qualified, and the other is to facilitate the next processing of the knitted felt. At present, the transfer of this type of knitted felt is mostly done manually. One or two workers grab the bottom of the knitted felt back and forth and slowly put the knitted felt on the mold. Since the knitted felt cannot be effectively grasped and force is applied, the operation is extremely troublesome. Moreover, the force on the upper and lower positions of the knitted felt is not uniform and it is easy to get stuck, resulting in the entire knitted felt transfer operation being extremely time-consuming and labor-intensive. Although the use of automated equipment can solve the above problems, the equipment purchase cost is relatively high.

[0003] Therefore, we propose a tool that is based on manual operation but can facilitate the transfer of knitted felt. Summary of the Invention

[0004] In view of the problem raised in the above background technology that the current manual transfer operation of knitted felt is time-consuming and labor-intensive, the present invention provides a knitted felt transfer tool.

[0005] The present invention discloses a knitted felt transfer tool, which specifically includes an upper shell, a bottom shell, a plurality of connecting beams and assembly bolts. The upper shell and the bottom shell are assembled and fixed by fixing bolts. This design is mainly for the convenience of replacing pins of different lengths according to production needs in the later stage. Conical sockets are evenly distributed on the panel of the bottom shell. A pin sleeve is vertically inserted into the interior of each of the conical sockets. The design of the conical sockets is mainly used to increase the strength of the connection between the pin sleeve and the bottom shell and improve the stability of the pin sleeve. The design of the pin sleeve not only serves to position and guide the pins, but also to fix the needle seat described below, so that after the upper shell and the bottom shell are assembled, the needle seat can be lifted up and tightly fitted into the inner side of the upper shell.

[0006] In order to facilitate the subsequent replacement of the pin model according to the needs of the operation, a needle seat is horizontally provided on the inner side of the upper shell, and fixing holes are evenly distributed on the needle seat. In addition, a pin for grabbing and applying force to the knitted felt body in real time is inserted from top to bottom in each fixing hole. The pin is inserted in the pin sleeve and extends to the outside of the bottom shell. When using the tool to transfer the knitted felt and apply force, the tool is attached to the surface of the knitted felt by holding the force-applying handle. It should be further explained that the extension length of the needle tip is determined according to the thickness of the knitted felt to be transferred. The size of the pin is generally selected so that the needle tip can only penetrate half of the thickness when it penetrates the interior of the knitted felt, and cannot cause damage to the internal body of the knitted felt.

[0007] In order to facilitate the free assembly and use of multiple basic units, a force-applying handle is also installed in the middle of the upper shell through a fixing bolt. The top of the upper shell near the four corners, as well as the two ends of the front and rear sides and the two ends of the left and right sides are respectively integrally formed with No. 1 threaded hole, No. 2 threaded hole and No. 3 threaded hole.

[0008] The tool solution recorded in the present invention is only a tool unit. In actual use requirements, multiple tool units are selected according to the required quantity and operation requirements, and are assembled by assembling bolts, connecting beams and threaded holes set at corresponding positions to form combined transfer tools of different forms. During the entire operation process, there is no need to pull from the bottom of the knitted felt as in traditional operations. Instead, force is applied downward simultaneously from the upper, middle and lower positions of the knitted felt according to the assembled tools to achieve a rapid transfer and assembly effect.

[0009] Furthermore, in order to enable multiple tool units to be freely assembled and angle-adjusted through the connecting beam and assembly bolts and in conjunction with corresponding threaded holes, the connecting beam is designed as a long strip structure as a whole, and a long strip slot is also provided in the middle of the connecting beam to adjust the position of the connecting beam on the two adjacent upper shells. The width of the slot matches the transverse diameter of the screw of the assembly bolt. The design of the long strip slot and its size is mainly to facilitate the adjustment of the position of the connecting beam during the assembly of two adjacent tool units, so as to facilitate the realization of multi-angle tool combinations.

[0010] Furthermore, in order to prevent the needle tip from extending too long and damaging the knitted felt and the mold, the needle sleeve is specifically composed of a tube body and an upper guide ring integrally formed at the upper end of the tube body, and an annular clamping ring is integrally formed on the inner side of the bottom end of the tube body; the outer side of the tube body is tightly fitted with the inner side of the conical socket and is fixed by an adhesive.

[0011] The insertion pin consists of a needle body and an anti-slip end and a needle tip integrally formed at both ends of the needle body. The anti-slip end fits tightly with the fixing hole, and the bottom end of the anti-slip end matches the shape and size of the inner side of the upper guide ring.

[0012] The outer size of the needle body matches the inner size of the tube body, and the size of the needle tip is consistent with the inner size of the clamping ring at the bottom end of the tube body.

[0013] The design of the upper guide ring is mainly to facilitate the assembly between the needle holder with the pin and the bottom shell. By guiding the needle tip, the pin can be smoothly inserted into the pin sleeve, and the size design of the needle tip and the retaining ring can effectively limit the extension length of the pin.

[0014] Furthermore, in order to further improve the fit between the needle seat and the upper shell, matching fitting grooves are integrally formed at the positions of all fixing holes in the upper shell, and the top of each fixing hole is interference fit in the matching groove at the corresponding position.

[0015] Furthermore, each of the pin sleeves corresponds to a pin, and the length of the needle tip at the bottom end of the pin extending out of the bottom shell includes but is not limited to 2-5 mm. The pin is a stainless steel needle with a thickness including but not limited to 1-3 mm, wherein the extension length of the needle tip is determined according to the model and specification of the transferred knitted felt, and the extension length of the needle tip is mainly based on the depth of the needle tip entering half of the knitted felt to avoid the needle tip damaging the knitted felt, and the thickness of the pin is also determined according to the pin length, mainly to ensure that when selecting a pin of corresponding length, its strength can be ensured at the same time.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The transfer tool described in the present invention can freely select multiple basic unit devices to combine and assemble different angles according to actual application needs, so as to facilitate the transfer set operation of the knitted felt. It is highly practical and easy to operate. It can more easily grasp and apply force to the surface of the knitted felt through different combination forms, so that the force on the upper and lower positions of the surface of the knitted felt is more uniform when the knitted felt is transferred, preventing the knitted felt from being stuck when moving downward, and improving the transfer and assembly efficiency of the knitted felt. Moreover, the pins in the tool can be selected to different lengths according to the thickness of the knitted felt to avoid damage to the knitted felt when the device is in use.

[0028] See also Figure 1 、 Figure 2The present invention discloses a knitted felt transfer tool, which specifically includes an upper shell 1, a bottom shell 2, a plurality of connecting beams 13 and assembly bolts 11. The upper shell 1 and the bottom shell 2 are assembled and fixed by fixing bolts 10. This design is mainly for the convenience of replacing pins 6 of different lengths according to production requirements in the later stage. Conical sockets 3 are evenly distributed on the panel of the bottom shell 2, and a pin sleeve 4 is vertically inserted into the interior of each conical socket 3. The design of the conical socket 3 is mainly used to increase the strength of the connection between the pin sleeve 4 and the bottom shell 2 and improve the stability of the pin sleeve 4. The design of the pin sleeve 4 not only serves to position and guide the pin 6, but also to fix the needle seat 5 described below, so that after the upper shell 1 and the bottom shell 2 are assembled, the needle seat 5 can be lifted up and fit tightly against the inner side of the upper shell 1.

[0029] See also Figure 1 、 Figure 4 In order to facilitate the subsequent replacement of the pin 6 model according to operational requirements, a needle seat 5 is horizontally provided on the inner side of the upper shell 1, and fixing holes 501 are evenly distributed on the needle seat 5, and a pin 6 for real-time grasping and applying force to the knitted felt body 15 is inserted from top to bottom in each fixing hole 501. The pin 6 is inserted in the pin sleeve 4 and extends to the outside of the bottom shell 2. In the process of using the tool to transfer and apply force to the knitted felt, the side of the tool with the needle tip 603 is attached to the surface of the knitted felt by holding the force-applying handle 12. It should be further explained that the extension length of the needle tip 603 is determined according to the thickness of the knitted felt to be transferred. The selected size of the pin 6 is generally such that the extension length of the needle tip 603 can only penetrate half of the thickness when the needle tip 603 penetrates the interior of the knitted felt, and cannot cause damage to the internal body of the knitted felt.

[0030] See also Figure 1 、 Figure 2 In order to facilitate the free assembly and use of multiple basic units, a force-applying handle 12 is also installed in the middle of the upper shell 1 through a fixing bolt 10. The top of the upper shell 1 near the four corners, as well as the two ends of the front and rear sides and the two ends of the left and right sides are respectively integrally formed with No. 1 threaded hole 7, No. 2 threaded hole 8 and No. 3 threaded hole 9.

[0031] The tool scheme described in the present invention is only one tool unit. In actual use, multiple tool units can be selected according to the required quantity and operation requirements, and assembled by assembling bolts 11, connecting beams 13 and threaded holes set at corresponding positions to form combined transfer tools of different forms, such as the attached Figure 2 , Attachment Figure 3 and attached Figure 5 During the whole operation, there is no need to pull from the bottom of the knitted felt as in the traditional operation. Instead, according to the assembled tools, force is applied from the top, middle and bottom of the knitted felt at the same time. Figure 6 As shown, a quick transfer assembly effect is achieved.

[0032] See also Figure 2 、 Figure 3 、 Figure 5 In order to enable multiple tool units to be freely assembled and angle-adjusted through the connecting beam 13 and the assembly bolts 11 and in conjunction with the corresponding threaded holes, the connecting beam 13 is designed as a long strip structure. A long strip slot is also provided in the middle of the connecting beam 13 to adjust the position of the connecting beam 13 on the two adjacent upper shells 1. The width of the slot matches the transverse diameter of the screw of the assembly bolt 11. The design of the long strip slot and its size is mainly to facilitate the adjustment of the position of the connecting beam 13 when assembling two adjacent tool units, so as to facilitate the realization of multi-angle tool combination.

[0033] See also Figure 4 In order to prevent the needle tip 603 of the pin 6 from extending too long and damaging the knitted felt body 15 and the mold 14, specifically, the pin sleeve 4 is composed of a tube body 401 and an upper guide ring 403 integrally formed at the upper end of the tube body 401, and an annular clamping ring 402 is integrally formed on the inner side of the bottom end of the tube body 401; the outer side of the tube body 401 is tightly fitted with the inner side of the conical socket 3 and fixed by an adhesive.

[0034] The insertion pin 6 consists of a needle body 601 and an anti-slip end 602 and a needle tip 603 integrally formed at both ends of the needle body 601. The anti-slip end 602 fits tightly with the fixing hole 501, and the bottom end of the anti-slip end 602 matches the shape and size of the inner side of the upper guide ring 403.

[0035] The outer dimensions of the needle body 601 match the inner dimensions of the tube body 401 , and the dimensions of the needle tip 603 are consistent with the inner dimensions of the clamping ring 402 at the bottom end of the tube body 401 .

[0036] The design of the upper guide ring 403 is mainly to facilitate the assembly between the needle seat 5 with the pin 6 and the bottom shell 2. By guiding the needle tip 603, the pin 6 can be smoothly inserted into the pin sleeve 4, and the size design of the needle tip 603 and the retaining ring 402 can effectively limit the extension length of the pin 6.

[0037] See also Figure 4 In order to further improve the fit between the needle seat 5 and the upper shell 1, matching fitting grooves 101 are integrally formed at the positions of all fixing holes 501 in the upper shell 1, and the top of each fixing hole 501 is interference fit in the matching groove 101 at the corresponding position.

[0038] Each pin sleeve 4 corresponds to a pin 6, and the length of the needle tip 603 at the bottom end of the pin 6 extending out of the bottom shell 2 includes but is not limited to 2-5 mm. The pin 6 is a stainless steel needle with a thickness including but not limited to 1-3 mm. The extension length of the needle tip 603 is determined according to the model and specification of the transferred knitted felt. The extension length of the needle tip 603 is mainly determined by the depth of the needle tip 603 entering half of the knitted felt to avoid the needle tip 603 damaging the knitted felt. The thickness of the pin 6 is also determined according to the length of the pin 6, mainly to ensure that when the pin 6 of the corresponding length is selected, its strength can be ensured at the same time.
