Description

Technical Field

[0001] This utility model belongs to the field of spraying technology and relates to an auxiliary tooling for spraying the end face of a T-shaped irregular part. Background Technology

[0002] To ensure the aerodynamic performance of the aircraft, during the production process, various internal components must conform to the overall mainstream design of the aircraft. This means that the internal components are primarily irregularly shaped structures, such as T-shaped parts. A T-shaped part includes a crossbar and a spray bar connected to the center of the crossbar. Both the crossbar and the spray bar are bent, and the bottom of the spray bar is concave inwards, forming a dihedral. In the later stages of production, the T-shaped part requires surface treatment processes, such as spraying, on the bottom surface of the spray bar and the top surface of the crossbar, to form the functional coating required for production.

[0003] Currently, during the spraying process, technicians manually place the T-shaped parts directly in front of the nozzle and adjust the angle to ensure their stability. However, due to the irregular shape of the T-shaped parts, they are not easy to fix. This requires technicians to have skilled operation techniques during placement. If problems occur during placement, the stability of the T-shaped parts will be greatly reduced, which will decrease the efficiency of the spraying surface treatment on the end face of the T-shaped parts and may even cause the parts to be scrapped. Therefore, it will greatly delay the production schedule and become a bottleneck in production.

[0004] In view of this, the present invention provides an auxiliary tooling for spraying the end face of T-shaped irregular parts to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose an auxiliary tooling for spraying the end face of a T-shaped part. In use, the crossbar of the T-shaped part is placed on the first or second support member, and the spray bar of the T-shaped part is supported by moving the sliding component to a suitable position. This effectively avoids the problem of insufficient stability of the T-shaped part caused by incorrect placement angle, thereby improving the spraying efficiency of the end face of the T-shaped part. Furthermore, by moving the sliding component, this auxiliary tooling can be adapted to various T-shaped parts with different spray bar lengths, making it widely applicable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A T-shaped irregular part end face spraying auxiliary tooling includes a base, on which a first support and a second support are respectively provided on two parallel sides of the upper surface of the base for supporting the crossbar of the T-shaped irregular part, and a sliding assembly for supporting the spray bar of the T-shaped irregular part is provided in the middle of the base, the sliding assembly sliding along the line connecting the first support and the second support.

[0008] Furthermore, the sliding component is an I-shaped slider, and a through groove is provided in the middle of the base, in which the I-shaped slider is slidably installed;

[0009] The I-shaped slider includes an upper waist plate, a web plate, and a lower waist plate that are detachably connected from top to bottom. The web plate is located in the through groove, and the height of the web plate is equal to the depth of the through groove. The upper waist plate and the lower waist plate are in contact with the upper and lower surfaces of the base, respectively.

[0010] Furthermore, the sliding assembly includes a slide rail and a slider slidably mounted on the slide rail, and a groove is provided in the middle of the base, with the slide rail fixedly mounted in the groove.

[0011] Furthermore, the sliding assembly includes a slide rail and a slider slidably mounted on the slide rail, the slide rail being fixedly disposed on the upper surface of the base.

[0012] Furthermore, an auxiliary tooling for spraying the end face of a T-shaped irregular part also includes a limit switch for limiting the displacement of the sliding component, the limit switch being installed in a through groove or recess.

[0013] Furthermore, there are two limit switches, located at both ends of the sliding component in the sliding direction.

[0014] Furthermore, an inverted V-shaped limiting component is provided between the second support member and the sliding assembly. The inverted V-shaped limiting component includes a first limiting plate and a second limiting plate. The first limiting plate and the second limiting plate are respectively inclined and fixed on both sides of the sliding assembly. The first limiting plate and the second limiting plate are detachably connected.

[0015] Furthermore, the inverted V-shaped limiting component also includes a connecting rod, the two ends of which are detachably connected to the first limiting plate and the second limiting plate, respectively.

[0016] Furthermore, it also includes several sets of adjustment components. Each set of adjustment components includes an adjustment screw and a locking nut that is sleeved on the adjustment screw and threaded to the rod of the adjustment screw. The base has several through holes. The inner diameter of the through holes is larger than the outer diameter of the adjustment screw and smaller than the diameter of the outer circle of the locking nut. One end of the adjustment screw is fixedly connected to the bottom end of the first support or the second support, and the other end of the adjustment screw passes through the through holes.

[0017] Furthermore, the first support member and the second support member are support columns or support blocks.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides an auxiliary tooling for spraying the end face of a T-shaped irregular part. In use, the crossbar of the T-shaped irregular part is placed on the first support or the second support. The sliding component is moved to a suitable position to support the spray bar of the T-shaped irregular part. This effectively avoids the problem of insufficient stability of the T-shaped irregular part caused by incorrect placement angle, thereby improving the spraying efficiency of the end face of the T-shaped irregular part. Moreover, by moving the sliding component, the auxiliary tooling can be adapted to various T-shaped irregular parts with different spray bar lengths, and has a wide range of applications.

[0020] 2. In the T-shaped irregular part end face spraying auxiliary tooling provided by this utility model, an inverted V-shaped limiting component is provided between the second support member and the sliding component. During use, the spray bar is located in the included angle area formed by the first limiting plate, the second limiting plate, and the connecting rod, thereby limiting the left and right and up and down displacement of the T-shaped irregular part under the cooperative action of the first limiting plate, the second limiting plate, and the connecting rod.

[0021] 3. In the T-shaped irregular part end face spraying auxiliary tooling provided by this utility model, by rotating the locking nut, the first support block and the second support block connected to the adjusting screw can be moved up and down, thereby realizing the height adjustment of the first support and the second support. When the T-shaped irregular part is placed on the auxiliary tooling, the T-shaped irregular part can be in a state where one side is high and the other side is low, and the higher side faces the nozzle. This makes the area to be sprayed on the T-shaped irregular part present a better appearance and is suitable for spraying equipment with different nozzle heights, thus improving the spraying efficiency.

[0031] Exemplary embodiments will now be described in detail. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses consistent with some aspects of this invention as detailed in the appended claims.

[0032] like Figure 1 As shown, this utility model provides an auxiliary tooling for spraying the end face of a T-shaped irregular part, including a base 1, a first support member 2, a second support member 3, and a sliding assembly. The first support member 2 and the second support member 3 are respectively arranged on two parallel sides on the upper surface of the base 1. The first support member 2 and the second support member 3 are both used to support the crossbar of the T-shaped irregular part. During use, the first support member 2 or the second support member 3 contacts the arc-shaped surface of the crossbar of the T-shaped irregular part.

[0033] The sliding assembly is disposed in the middle of the base 1 and is located between the first support member 2 and the second support member 3. It can slide along the line connecting the first support member 2 and the second support member 3. The sliding assembly is used to support the T-shaped spray bar. Specifically, during use, the sliding assembly contacts the arc-shaped surface of the T-shaped spray bar.

[0034] The first support member 2 and the second support member 3 can both be support columns or support blocks, or they can be arranged in combination as support columns or support blocks. The support column can be inverted L-shaped, thereby improving the load-bearing capacity of the T-shaped irregular part.

[0035] Preferably, there are two first support members 2 and two second support members 3. Each first support member 2 has the same height, and each second support member 3 has the same height. The line connecting the two first support members 2 and the line connecting the two first support members 2 are perpendicular to the sliding direction of the sliding assembly. This ensures that when the first support members 2 and the second support members 3 support the crossbar of the T-shaped part, the crossbar always remains straight. This ensures that the area to be sprayed on the top end face of the crossbar and the area to be sprayed on the bottom end face of the spray bar are always at the same distance from the nozzle, thereby ensuring the uniformity of the spraying.

[0036] Furthermore, such as Figure 3 As shown, an auxiliary tooling for spraying the end face of a T-shaped irregular part also includes a limit switch 8. The limit switch 8 is installed in the through groove 5 or the recess, and is used to limit the displacement of the sliding component. The type of limit switch 8 can be preset according to the usage requirements. For example, the limit switch 8 can be a limit switch or a limit plate. The movement of the sliding component can be limited by the limit switch 8 to avoid displacement deviation of the sliding component during use.

[0037] Preferably, there are two limit switches 8, located at both ends of the sliding component in the sliding direction. The sliding component can contact the limit switches 8 during the sliding process, and the two limit switches 8 limit the left and right displacement of the sliding component.

[0038] Furthermore, such as Figure 4 As shown, the system also includes several sets of adjustment components. Each set of adjustment components includes an adjustment screw 9 and a locking nut 10 that is sleeved on the adjustment screw 9 and threadedly connected to the rod portion of the adjustment screw 9. The base 1 has several through holes, the inner diameter of which is larger than the outer diameter of the adjustment screw 9. One end of the adjustment screw 9 is fixedly connected to the bottom end of the first support member 2 or the second support member 3, and the other end of the adjustment screw 9 passes through the through holes on the base 1. The adjustment components are used to adjust the height of the first support member 2 and the second support member 3, and the walls of the several through holes can all be smooth.

[0039] The adjusting screw 9 has an external thread on its rod portion, and the locking nut 10 has an internal thread that matches the external thread on the rod portion of the adjusting screw 9. The diameter of the outer circle of the locking nut 10 is larger than the inner diameter of the through hole.

[0040] The size and material of the adjusting screw 9 can be preset according to the usage requirements. For example, the material of the adjusting screw 9 can be alloy structural steel, stainless steel, etc. This application embodiment does not make specific limitations on this.

[0041] The height adjustment methods for the first support member 2 and the second support member 3 are the same. The following is an example using the first support member 2, and the specific process is as follows:

[0042] When it is necessary to raise the first support member 2, lift the first support member 2 upward to a suitable height, rotate the locking nut 10 downward until the locking nut 10 contacts the upper surface of the base plate 1, stop rotating the locking nut 10, and the height of the first support member 2 is completed.

[0043] When it is necessary to lower the first support member 2, rotate the locking nut 10 upwards. Due to its own weight, the adjusting screw 9 moves downwards, thereby driving the first support member 2 to move down. When the first support member 2 moves down to a suitable height, stop rotating the locking nut 10 to complete the reduction of the height of the first support member 2.

[0044] During the upward rotation of the locking nut 10, since the diameter of the locking nut 10 is much larger than the diameter of the through hole and the locking nut 10 is threadedly connected to the adjusting screw 9, the locking nut 10 is always in contact with the upper surface of the base plate 1 and is stuck on the upper surface of the base plate 1.

[0045] Furthermore, an auxiliary tooling for spraying the end face of a T-shaped irregular part also includes an inverted V-shaped limiting component disposed between the second support member 3 and the sliding component. The inverted V-shaped limiting component can have various structures, and the specific structure of the inverted V-shaped limiting component will be described below.

[0046] The first type of inverted V-shaped limiting component structure: such as Figure 5 As shown, the inverted V-shaped limiting component includes a first limiting plate 11 and a second limiting plate 12. The first limiting plate 11 and the second limiting plate 12 are respectively inclined and fixed on both sides of the sliding assembly. The first limiting plate 11 and the second limiting plate 12 are detachably connected. During use, since the first limiting plate 11 and the second limiting plate 12 form a downward-opening angle, the spray bar is located within the angled area formed by the first limiting plate 11 and the second limiting plate 12. The first limiting plate 11 and the second limiting plate 12 work together to limit the left and right displacement of the T-shaped irregular part.

[0047] The second type of inverted V-shaped limiting component structure: such as Figure 6As shown, the inverted V-shaped limiting component also includes a connecting rod 13, the two ends of which are detachably connected to the first limiting plate 11 and the second limiting plate 12, respectively. Specifically, the connection method between the connecting rod 13 and the first and second limiting plates 11 and 12 can be as follows: threaded holes matching the connecting rod 13 are opened at different heights of the first and second limiting plates 11 and 12, and the two ends of the connecting rod 13 extend out of the threaded holes and are fixedly connected by nuts. During use, the spray bar is located within the angled area formed by the first limiting plate 11, the second limiting plate 12, and the connecting rod 13. The connecting rod 13, in conjunction with the first and second limiting plates 11 and 12, limits the vertical displacement of the T-shaped component.

[0048] Furthermore, sliding components can have various structures, and the specific structures of sliding components are described below.

[0049] The first type of sliding component structure: as follows Figure 1 As shown, the sliding component is an I-shaped slider 4. A through groove 5 is provided in the middle of the base 1. The I-shaped slider 4 is slidably installed in the through groove 5. The I-shaped slider 4 includes an upper waist plate, a web plate, and a lower waist plate that are detachably connected from top to bottom. The web plate is located in the through groove 5. The height of the web plate is equal to the depth of the groove. The upper waist plate and the lower waist plate are in contact with the upper and lower surfaces of the base 1, so that the I-shaped slider 4 can slide left and right in the through groove 5.

[0050] To further ensure high spraying efficiency, two I-beam sliders 4 can be used, with a height difference of 5-7 cm between them. When surface treating the top end face of the crossbar of the T-shaped part, the spray bar of the T-shaped part can be placed on the lower I-beam slider 4. When surface treating the bottom end face of the spray bar of the T-shaped part, the spray bar can be placed on the higher I-beam slider 4. This ensures that the end of the T-shaped part facing the nozzle is always higher than the end of the T-shaped part away from the nozzle, resulting in a better spraying area on the T-shaped part and improving spraying efficiency.

[0051] The second type of sliding component structure: such as Figure 2 As shown, the sliding assembly includes a slide rail 6 and a slider 7. The slider 7 is slidably mounted on the slide rail 6 and can move along the track of the slide rail 6.

[0052] Specifically, the installation method of the slide rail 6 can be any of the following.

[0053] (1) A groove is provided in the middle of the base 1, the slide rail 6 is fixedly installed in the groove, and the lower surface of the slider 7 can contact the bottom of the groove or the upper surface of the base 1.

[0054] (2) The slide rail 6 is fixedly installed on the upper surface of the base 1.

[0055] The number of sliders 7 can also be two, and the heights of the two sliders 7 are different, specifically by 5 to 7 cm, for the same reason as the I-shaped slider 4, so it will not be repeated here.

[0056] This utility model provides an auxiliary tooling for spraying coating the end face of a T-shaped irregular part. The specific workflow is as follows:

[0057] When using this spraying auxiliary fixture to assist in spraying the top end face of the crossbar of the T-shaped part, first fix the base 1 in front of the spraying equipment, then place both ends of the crossbar of the T-shaped part on the first support 2, move the sliding component so that the bottom of the spray bar of the T-shaped part is on the sliding component, then adjust the height of the first support 2 until the top end face of the crossbar of the T-shaped part is directly facing the nozzle, connect the first limiting plate 11 and the second limiting plate 12, and install the connecting rod 13. At this time, the spray bar of the T-shaped part is located between the first limiting plate 11, the second limiting plate 12, and the connecting rod 13 to limit the left and right and up and down displacement of the T-shaped part. Finally, turn on the spraying equipment and spray the top end face of the crossbar of the T-shaped part through the nozzle. After the spraying is completed, disassemble the connection between the first limiting plate 11 and the second limiting plate 12, remove the connecting rod 13, and take off the T-shaped part.

[0058] When using this spraying auxiliary fixture to assist in spraying the bottom end face of the spray bar of the T-shaped part, first fix the base 1 in front of the spraying equipment, then place both ends of the crossbar of the T-shaped part on the second support 3, move the sliding component so that the bottom of the spray bar of the T-shaped part is on the sliding component, then adjust the height of the second support 3 until the bottom end face of the spray bar of the T-shaped part is directly facing the nozzle, connect the first limiting plate 11 and the second limiting plate 12, and install the connecting rod 13. At this time, the spray bar of the T-shaped part is located between the first limiting plate 11, the second limiting plate 12, and the connecting rod 13 to limit the left and right and up and down displacement of the T-shaped part. Finally, turn on the spraying equipment and spray the bottom end face of the spray bar of the T-shaped part through the nozzle. After the spraying is completed, disassemble the connection between the first limiting plate 11 and the second limiting plate 12, remove the connecting rod 13, and take off the T-shaped part.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
