Description

Technical Field

[0001] This utility model relates to the field of air conditioner casing processing technology, specifically to an air conditioner casing drilling device. Background Technology

[0002] Air conditioners, as common cooling and heating devices, are widely used in homes, businesses, and industries. During the manufacturing and assembly of an air conditioner casing, multiple pieces of the casing are typically cut to a fixed size. Holes are then punched into the edges of these pieces. Finally, the six individual casing pieces are joined together with the corresponding holes and secured with rivets to form the complete casing assembly.

[0003] For mature parts like air conditioner housings, the positions of the mounting holes are basically fixed. Therefore, the most commonly used air conditioner housing punching device is a multi-point stamping forming device formed by multiple fixed punching heads. By pre-setting the position of the punching head to correspond with the position of the mounting hole on the housing to be punched, multiple mounting holes can be formed in one punching. The process is simple and convenient.

[0004] However, in practical use, although this device can form multiple holes on a single housing in one go, the size of each side of the air conditioner housing is different and the spacing between the points is not fixed. Therefore, it is difficult for the same punching device to form holes on different sides. It is necessary to adjust the spacing of the punching heads in advance or replace the punching module, which is quite troublesome to use. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioner casing drilling device to solve the technical problem that the fixed spacing of the punch heads on the multi-point drilling device makes it more troublesome to use.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] An air conditioner casing punching device includes a punching table, a platform for supporting the air conditioner casing is provided on the top surface of the punching table, there is a clearance between the outer side of the platform and the top surface of the punching table, and multiple standard die holes are linearly arranged on the bearing surface of the platform along the length direction of the platform, with the centers of the multiple standard die holes being collinear.

[0008] A stamping plate is installed above the standard die hole. The stamping plate is mounted on the punching table via a telescopic stamping column. The stamping plate has multiple vertical mounting holes. The two ends of the vertical mounting holes are located directly above the standard die hole and the clearance gap, respectively. A stamping head is slidably installed inside the vertical mounting hole along the length of the vertical mounting hole. The stamping head is connected to a quick-adjustment structure, which is installed on the stamping plate. The quick-adjustment structure is used to push the stamping head to slide within the vertical mounting hole to selectively apply the stamping head.

[0009] As a preferred embodiment of this utility model, two rows of vertical mounting holes are provided on the stamping plate and are respectively located at positions corresponding to the standard mold holes. Each row of vertical mounting holes has three holes, and a stamping head is slidably disposed in each vertical mounting hole.

[0010] Among the stamping heads in the same row, the stamping heads on both sides are connected to the stamping head in the middle through rotating arms. The rotating arms are rotatably mounted on the stamping plate, and the two ends of the rotating arms are rotatably connected to the top of the stamping head. The stamping heads on both sides are connected to the quick-adjustment structure. The quick-adjustment structure is used to push the stamping heads on both sides to slide linearly in the vertical mounting hole, and simultaneously drive the stamping head in the middle to slide in the opposite direction in the vertical mounting hole.

[0011] As a preferred embodiment of this utility model, the quick-adjustment structure includes two sets of toothed plate assemblies, which are respectively connected to the outer stamping heads. Each set of toothed plate assemblies includes two toothed plates, which are respectively connected to two stamping heads on the same side of opposite rows. The two toothed plates are slidably arranged on the stamping plate with their teeth facing each other. A drive gear is rotatably arranged between the two toothed plates, and a fixed driver is coaxially connected to the drive gear.

[0012] As a preferred embodiment of this utility model, the stamping head includes a stamping main rod, one end of which is positioned below the stamping plate and facing the platform, and the other end of which is connected to the toothed plate or rotating arm above the stamping plate. A pressure-bearing block is coaxially fixedly arranged in the middle of the stamping main rod, and the pressure-bearing block is slidably fitted into a limiting groove. The limiting groove is opened on the inner wall of the vertical mounting hole along the length direction of the vertical mounting hole.

[0013] As a preferred embodiment of this utility model, the platform includes two parallel stringers, standard mold holes are respectively set on the two stringers, the stringers are connected by multiple support columns, and a material passage gap is provided between adjacent support columns.

[0014] As a preferred embodiment of this utility model, additional die holes are provided on both sides of the standard die hole on the stringer, and fixed mounting holes are provided on both sides of the vertical mounting hole on the stamping plate. Additional stamping heads are fixedly installed in the fixed mounting holes, and the additional stamping heads are positioned directly opposite the additional die holes.

[0015] As a preferred embodiment of this utility model, the punching platform is provided with a waste chamber, which has a top opening and a side opening. The top opening of the waste chamber is located between two stringers.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention features at least two sets of punching heads, each corresponding to punching mounting holes with different spacings. A quick-adjustment structure is also included; the rotation of a fixed driver moves the toothed plate and slides the punching heads, ensuring that only one set of punching heads is always positioned above the standard die hole, while the other set is positioned above the clearance gap. This allows for the selection of the appropriate punching head to match the corresponding mounting hole. This device is simple, quick, and easy to use, suitable for air conditioner housings requiring holes with different spacings. It is particularly efficient for switching between housings with unequal hole spacings but fixed hole spacings, offering high efficiency and fast switching when changing housings for punching holes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, this utility model provides an air conditioner casing drilling device, including a punching table 1. The top surface of the punching table 1 is provided with a platform 2 for supporting the air conditioner casing. There is a clearance gap 3 between the outer side of the platform 2 and the top surface of the punching table 1. Multiple standard die holes 4 are linearly arranged on the bearing surface of the platform 2 along the length direction of the platform 2. The centers of the multiple standard die holes 4 are collinear.

[0027] A stamping plate 5 is provided above the standard die hole 4. The stamping plate 5 is mounted on the punching table 1 via a telescopic stamping column 6. The stamping plate 5 has multiple vertical mounting holes 7. The two ends of the vertical mounting holes 7 are located directly above the standard die hole 4 and the clearance gap 3, respectively. A stamping head 8 is slidably arranged inside the vertical mounting hole 7 along the length direction of the vertical mounting hole 7. The stamping head 8 is connected to a quick-adjustment structure 9, which is set on the stamping plate 5. The quick-adjustment structure 9 is used to push the stamping head 8 to slide within the vertical mounting hole 7 to selectively apply the stamping head 8.

[0028] Two rows of vertical mounting holes 7 are provided on the stamping plate 5, and are respectively set at positions corresponding to the standard die holes 4. There are three vertical mounting holes 7 in each row, and a stamping head 8 is slidably installed in each vertical mounting hole 7.

[0029] Among the stamping heads 8 in the same row, the stamping heads 8 on both sides are connected to the middle stamping head 8 through rotating arms 10. The rotating arms 10 are rotatably mounted on the stamping plate 5, and the two ends of the rotating arms 10 are rotatably connected to the top of the stamping head 8. The stamping heads 8 on both sides are connected to the quick-adjustment structure 9. The quick-adjustment structure 9 is used to push the stamping heads 8 on both sides to slide linearly in the vertical mounting hole 7, and simultaneously drive the middle stamping head 8 to slide in the opposite direction in the vertical mounting hole 7.

[0030] The quick-adjustment structure 9 includes two sets of toothed plate assemblies 11, which are respectively connected to the outer stamping head 8. Each set of toothed plate assemblies 11 includes two toothed plates 12, which are respectively connected to two stamping heads 8 on the same side of opposite rows. The two toothed plates 12 are slidably arranged on the stamping plate 5 with their teeth facing each other. The specific sliding connection method can be set by the connection method of slider and slide groove in the prior art. A drive gear 13 is rotatably arranged between the two toothed plates 12, and a fixed driver 14 is coaxially connected to the drive gear 13.

[0031] The stamping head 8 includes a stamping main rod 15. One end of the stamping main rod 15 is positioned below the stamping plate 5 and facing the platform 2, while the other end is connected to the toothed plate 12 or the rotating arm 10 above the stamping plate 5. A pressure-bearing block 16 is coaxially fixedly mounted in the middle of the stamping main rod 15. The pressure-bearing block 16 is slidably fitted into a limiting groove 17, which is formed along the length of the vertical mounting hole 7 on the inner wall of the vertical mounting hole 7. In this device, the impact force of the stamping head 8 when it presses down to punch a hole is received by the pressure-bearing block 16 and transmitted to the stamping plate 5, thus preventing impact damage to the rotating arm 10 or the toothed plate 12.

[0032] like Figure 1 As shown, the platform 2 includes two parallel stringers 18, with standard die holes 4 respectively set on the two stringers 18. The stringers 18 are connected by multiple supports 19, and a material passage gap 20 is provided between adjacent supports 19. Additional die holes 21 are provided on both sides of the standard die holes 4 on the stringers 18. Fixed mounting holes 22 are provided on both sides of the vertical mounting holes 7 on the stamping plate 5. Additional stamping heads 23 are fixedly installed in the fixed mounting holes 22, and the additional stamping heads 23 are positioned directly opposite the additional die holes 21. The punching table 1 has a scrap chamber 24 inside, which has a top opening and a side opening. The top opening of the scrap chamber 24 is located between the two stringers 18. The supports 19 can support the shell, making the punching process more stable, and the material passage gap 20 formed can allow some scrap to fall into the scrap chamber 24, realizing the material collection process.

[0033] The main problem addressed by this utility model is that, due to the inconsistent spacing of the mounting holes on different sides of the air conditioner housing, when the air conditioner housings on different sides are placed on the same device for drilling, the spacing of the punching heads 8 needs to be adjusted. However, frequently adjusting the position of the punching heads 8 is cumbersome and can easily lead to errors in the position adjustment.

[0034] For example, the front and side housings of an air conditioner have the same length and can be placed on the same stamping base. However, because the width of the side housing is narrower than that of the front housing, the number of mounting holes on it is less than that on the front housing, and the spacing between the mounting holes is generally smaller than the spacing between adjacent holes on the front housing. Therefore, in actual use, either the front housing and the side housing are drilled on two separate sets of drilling dies, or two sets of standard die holes 4 are drilled on the stamping base of the same drilling die. However, the stamping head 8 of this set of drilling dies is set as an adjustable-pitch stamping head 8 to match the two sets of standard die holes 4.

[0035] Furthermore, setting two sets of standard die holes 4 on the same set of die holes is simpler than setting two sets of opening molds. In this mode, the adjustment process of changing the two sets of standard die holes 4 for matching applications is complex and cumbersome in existing technologies. However, in this device, this adjustment process is simple and efficient.

[0036] Specifically, such as Figure 1 As shown, in one embodiment, the stamping plate 5 is provided with two rows of stamping heads 8, with five stamping heads 8 in each row. The two outermost stamping heads 8 (with added stamping head 23) and the middle stamping head 8 are in the same group and are used on the front-view housing of the air conditioner (this housing is relatively wide, and generally has three mounting holes on the upper and lower edges, corresponding to these three stamping heads 8). The remaining stamping heads 8 located on both sides of the middle stamping head 8 are in the same group and are used on the side-view housing of the air conditioner (this housing is relatively wide, and generally has two mounting holes on the upper and lower edges, corresponding to these two stamping heads 8).

[0037] When punching holes in the front-view housing of the air conditioner, the fixed drive 14 rotates clockwise, which drives the punching heads 8 on both sides of the middle to move upward through the toothed plate 12, moving them out of the area above the platform 2 and above the clearance gap 3. At the same time, the rotating arm 10 drives the middle punching head 8 to move from above the clearance gap 3 to above the standard die hole 4. At this time, the middle punching head 8 and the two outermost punching heads 8 (additional punching heads 23) are all above the standard die hole 4 (the additional punching heads 23 are fixedly set on the stamping plate 5 and are directly above the additional die hole 21. The additional die hole 21 and the standard die hole 4 are arranged in the same linear order and are collinear with the center of the standard die hole 4). The punching heads 8 on both sides of the middle are above the clearance gap 3, so the telescopic punching column 6 can drive the punching heads 8 to press down and punch holes.

[0038] Similarly, when punching holes in the side-view housing of the air conditioner, the two punch heads 8 on the middle two sides need to be moved above the standard die hole 4. By rotating the fixed driver 14 counterclockwise, the punch heads 8 on the middle two sides move down, and the punch head 8 in the middle moves up, so that the punch heads 8 on the middle two sides are above the standard die hole 4. Importantly, since the side-view housing of the air conditioner is narrower than the front-view housing, when the side-view housing of the air conditioner is placed on the platform 2, its two side edges will not reach the position of the additional punch head 23. That is to say, when punching the side-view housing of the air conditioner, there is no shell between the additional punch head 23 and the additional die hole 21. When the stamping plate 5 falls, the additional punch head 23 will directly insert into the additional standard die hole 21, so it will not cause unnecessary punching to the side-view housing of the air conditioner. When punching holes in the front-view housing of the air conditioner, since its width is greater than that of the side-view housing of the air conditioner, there is a housing between the punching heads 8 on both sides and the standard die hole 4 when it is placed on the platform 2. Therefore, it needs to be moved to a position above the clearance gap 3.

[0039] The fixed driver 14 can use a drive motor from the prior art, or it can be rotated manually. Additionally, a cover can be installed outside the stamping plate 5 to protect the internal mechanisms.

[0040] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
