Description

Technical Field

[0001] This application relates to the technical field of stamping positioning, and in particular to a positioning device for stamping air conditioner sheet metal parts. Background Technology

[0002] Stamping is a machining process that uses dies and stamping equipment to apply pressure to sheet metal, causing it to undergo plastic deformation or separation, thereby obtaining parts of the desired shape and size. This technology is widely used in the automotive, home appliance, electronics, and aerospace industries, and is characterized by high efficiency, high precision, and low cost.

[0003] Currently, when punching large air conditioner sheet metal parts, due to the large overall area of ​​the parts, multiple operators are usually required to work together to move the sheet metal parts under the punching device. The corresponding punching position is aligned with the punch head located above, and the punch head descends to punch the edge of the air conditioner sheet metal part. After completing one punching operation, the air conditioner sheet metal part is manually moved to the next position for punching, and the above operation is repeated to complete the punching process for the air conditioner sheet metal parts.

[0004] Regarding the aforementioned technologies, the inventors believe that during the punching process of air conditioner sheet metal parts, due to their thinness, deformation is easily caused during the punching process and the manual adjustment and handling of the punching position, resulting in a reduction in the processing accuracy of the air conditioner sheet metal parts. Utility Model Content

[0005] In order to improve the quality and efficiency of punching sheet metal parts, this application provides a positioning device for stamping air conditioner sheet metal parts.

[0006] The positioning device for stamping air conditioner sheet metal parts provided in this application adopts the following technical solution:

[0007] A positioning device for stamping sheet metal parts for air conditioners includes an operating table, a support plate, and a connecting rod. A slide rail is provided on the top surface of the operating table, and the support plate is slidably mounted on the slide rail. A driving component is provided on the operating table for driving the support plate to move along the length direction of the slide rail. A plurality of stamping holes are formed on the support plate along its length direction, and the stamping holes are located on the side of the support plate near its width direction. The connecting rod is located on the top surface of the support plate and on the side of the support plate near the stamping holes.

[0008] By adopting the above technical solution, the sheet metal part is placed on the support plate, and one side of the sheet metal part abuts against the abutment rod. The drive unit drives the support plate to slide above the operating table. When it slides until one of the punching holes corresponds to the position of the upper punching device, the punching device performs a punching operation on the sheet metal part. The abutment rod limits the position of the sheet metal part, and the support plate supports the sheet metal part, reducing the possibility of deformation of the sheet metal part during the punching process. Through the cooperation of the operating table, the support plate, and the abutment rod, rapid positioning and punching of the sheet metal part are achieved, which improves the punching quality and efficiency of sheet metal parts.

[0009] Optionally, a movable plate is arranged parallel to the operating table and the support plate. The movable plate is provided with a plurality of movable rollers. The axial direction of the movable rollers is parallel to the abutment rod. The support plate has a plurality of connecting holes. The plurality of connecting holes and the plurality of movable rollers are arranged one-to-one in the vertical direction. A driving component for driving the support plate to rise and fall is provided between the movable plate and the support plate.

[0010] By adopting the above technical solution, when the sheet metal part is placed on the support plate, a portion of the moving roller protrudes from the top surface of the support plate, facilitating the operator to push the sheet metal part onto the support plate from one side of its width. After the sheet metal part is loaded, the drive unit drives the support plate to rise, and the moving roller separates from the sheet metal part. The sheet metal part is then stably and securely placed on the support plate, facilitating subsequent stamping operations.

[0011] Optionally, a plurality of guide plates are inclinedly connected to the bottom surface of the support plate, and the plurality of guide plates are arranged in a one-to-one correspondence with the plurality of punching holes.

[0012] By adopting the above technical solution, the guide plate discharges the waste generated by stamping, reducing the possibility that the waste will fall onto the moving plate and be difficult to collect and clean.

[0013] Optionally, a collection box is provided on one side of the operating table, and the top opening of the collection box is corresponding to the bottom end of the guide plate.

[0014] By adopting the above technical solution, the stamped waste slides along the guide plate and eventually falls into the collection box for collection, which improves the collection speed and convenience of waste.

[0015] Optionally, the driving component includes an incomplete gear and a driven rack. The driven rack is connected to one side of the moving plate, and the length direction of the driven rack is parallel to the slide rail. The incomplete gear is rotatably mounted on the operating table, and the operating table is provided with a driving source for driving the incomplete gear to rotate.

[0016] By adopting the above technical solution, when the moving plate is driven, the incomplete gear rotates under the driving action of the drive source, and the incomplete gear drives the moving plate and the driven rack at intervals. When the moving plate stops moving, one of the punching holes corresponds to the output end of the punching device in the vertical direction, and at this time the punching device punches holes in the sheet metal part.

[0017] Optionally, the support plate is provided with a clamping assembly, which includes clamping strips, sliding rods, and a clamping plate. Two clamping strips are provided on the support plate along a direction perpendicular to the abutment rod. The two clamping strips are respectively provided at both ends of the support plate along its length. Each of the two clamping strips has a clamping groove along its length on the side that is close to each other. The clamping plate is horizontally slidably disposed in the clamping groove. Two sliding rods are vertically disposed on the clamping plate. The two sliding rods pass through the clamping strips and are slidably connected to them. The clamping strips are provided with clamping drive components for driving the clamping plate to move in the vertical direction.

[0018] By adopting the above technical solution, the sheet metal part is pushed between two clamping strips, and the edge of the sheet metal part is embedded in the clamping groove of the corresponding clamping strip. The clamping drive component drives the clamping plate, which moves downward and presses the edge of the sheet metal part firmly against the support plate. The clamping assembly effectively clamps and fixes the sheet metal part, reducing the possibility of the sheet metal part sliding on the support plate during punching, which could lead to a decrease in punching accuracy.

[0019] Optionally, the clamping drive includes a rotating shaft, a drive cam, and a rotating handle. The rotating shaft is horizontally rotatably mounted on the clamping bar. One end of the rotating shaft extends into the clamping groove and is connected to the drive cam. The drive cam is located between the clamping plate and the inner top wall of the clamping groove. The end of the rotating shaft away from the drive cam extends out of the clamping bar and is connected to the rotating handle. An elastic element is provided between the clamping plate and the inner top wall of the clamping groove. In its natural state, the clamping plate abuts against the drive cam under the action of the elastic element.

[0020] By adopting the above technical solution, when clamping sheet metal parts, rotating the handle drives the rotating shaft and the drive cam to rotate. The drive cam presses down the clamping plate, clamping the edges of the sheet metal parts, thereby achieving rapid clamping of the sheet metal parts.

[0021] Optionally, one of the clamping bars is slidably connected to the support plate, and the movable plate is provided with a driving member for driving the clamping bar to move along the length direction of the abutment rod.

[0022] By adopting the above technical solution, since the position of one of the clamping strips can be adjusted, the spacing between the two clamping strips can be adjusted according to the specific length of the sheet metal part when clamping it, thus expanding the applicability of the clamping assembly.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of the operating table, support plate and abutment rod, the sheet metal parts are quickly positioned and stamped, which improves the quality and efficiency of sheet metal punching.

[0025] 2. The clamping assembly reduces the possibility of sheet metal parts sliding on the support plate during punching, which could lead to a decrease in punching accuracy;

[0026] 3. The design of the guide ramp and collection box improves the speed and convenience of waste collection. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be further described in detail below. Embodiments of this application provide a positioning device for stamping sheet metal parts for air conditioners, which improves the quality and efficiency of stamping sheet metal parts.

[0032] Reference Figure 1A positioning device for stamping sheet metal parts for air conditioners includes an operating table 1, a movable plate 2, a support plate 3, and a clamping assembly 4.

A plurality of lifting cylinders 5 are provided on the top surface of the movable plate 2, and the output shafts of the lifting cylinders 5 extend vertically upward and are connected to the support plates 3.

[0033] Reference Figure 1 Two slide rails 6 are arranged parallel to each other along the length of the top surface of the operating table 1. Two sliding grooves 21 are opened parallel to each other on the ground of the moving plate 2. The two slide rails 6 correspond one-to-one with the two sliding grooves 21 and are slidably connected. A drive motor 7 is provided on the top surface of the operating table 1. The output shaft of the drive motor 7 extends vertically downward and is connected to an incomplete gear 8. A driven rack 9 is connected to one side of the moving plate 2 along the length of the moving plate 2 in the width direction. The driven rack 9 is meshed with the incomplete gear 8 for transmission.

[0034] Reference Figure 1 A contact rod 10 is connected to the top surface of one side of the support plate 3 in the width direction. The contact rod 10 is arranged parallel to the driven rack 9. Several moving rollers 11 are rotatably arranged on the top surface of the movable plate 2. The central axis of the moving rollers 11 is arranged parallel to the length direction of the contact rod 10. Several connecting holes 31 are opened on the support plate 3, and the several connecting holes 31 correspond one-to-one with the several moving rollers 11 in the vertical direction.

[0035] Reference Figure 1 and Figure 2 The support plate 3 has several punched holes 32 along its length on the side near the abutment rod 10. Several guide ramps 12 are connected to the bottom surface of the support plate 3, with each guide ramp 12 corresponding to one of the punched holes 32. The bottom ends of the guide ramps 12 extend downwards at an angle. A collection box 13 with an open top is provided on one side of the operating table 1, with the open end of the collection box 13 corresponding to the bottom end of the guide ramps 12.

[0036] Reference Figure 2 and Figure 3The clamping assembly 4 is mounted on the support plate 3. The clamping assembly 4 includes clamping strips 41, clamping plates 42, sliding rods 43, limiting blocks 44, connecting springs 45, clamping pads 46, rotating shafts 47, driving cams 48, and rotating handles 49. Two clamping strips 41 are parallel to each other along the width direction on the top surface of the support plate 3, with each clamping strip 41 positioned at one end of the width direction. Clamping grooves 411 are formed on the sides of the two clamping strips 41 that are close to each other. One clamping plate 42 is horizontally positioned in each clamping groove 411, and the clamping pad 46 is connected to the bottom surface of the clamping plate 42. Two sliding rods 43 are vertically fixedly connected to the top surface of each clamping plate 42, and the two sliding rods 43 pass through the clamping strips 41 and are slidably connected to them. One limiting block 44 is connected to the top of each sliding rod 43. A connecting spring 45 is sleeved on the slide rod 43. One end of the connecting spring 45 is connected to the inner top wall of the clamping groove 411, and the other end is connected to the top surface of the clamping plate 42. A rotating shaft 47 is horizontally rotatably connected to the clamping bar 41. One end of the rotating shaft 47 extends into the clamping groove 411 and is connected to the drive cam 48, and the other end extends out of the clamping bar 41 and is connected to the rotating handle 49. In its natural state, the clamping plate 42 is pressed against the drive cam 48 under the action of the connecting spring 45.

[0037] Reference Figure 1 One of the clamping bars 41 is slidably connected to the support plate 3. The support plate 3 is provided with an adjusting cylinder 14, which is located on the side of the clamping bar 41 away from the other clamping bar 41. The output shaft of the adjusting cylinder 14 extends along the length of the abutment rod 10 and is connected to the movable clamping bar 41.

[0038] Reference Figure 1 Before punching the sheet metal parts, the distance between the two clamping strips 41 is adjusted using the adjusting cylinder 14 according to the length of the sheet metal parts, so that it can be adapted to the length of different sheet metal parts, thus expanding the applicability of the clamping assembly 4. The lifting cylinder 5 is activated, driving the support plate 3 to descend, and the top of the moving roller 11 extends out of the top surface of the support plate 3 through the connecting port 31. The operator pushes the sheet metal parts onto the support plate 3. The moving roller 11 reduces the friction on the sheet metal parts during the loading process. One side of the sheet metal parts abuts against the abutment rod 10 to achieve a limit. After the sheet metal parts are loaded, the lifting cylinder 5 drives the support plate 3 to rise, the sheet metal parts separate from the moving roller 11, and the sheet metal parts are stably placed on the top surface of the support plate 3, achieving stable support for the sheet metal parts.

[0039] Reference Figure 3Rotating the handle 49 causes the rotating shaft 47 and the drive cam 48 to rotate. Driven by the drive cam 48 and guided by the slide rod 43, the clamping plate 42 moves downwards, pressing both ends of the sheet metal part against the top surface of the support plate 3. The clamping assembly 4 provides stable clamping of the sheet metal part, reducing the possibility of it sliding on the top surface of the support plate 3 during stamping.

[0040] Reference Figure 1 and Figure 2 After the sheet metal parts are clamped and fixed, the drive motor 7 starts, driving the incomplete gear 8 to rotate. The driven rack 9 and the moving plate 2 move intermittently under the driving action of the incomplete gear 8 and the guiding action of the slide rail 6. When the moving plate 2 and the support plate 3 stop moving, one of the punching holes 32 on the support plate 3 is aligned vertically with the punching head of the stamping device, and the stamping device punches the sheet metal parts. The waste generated during stamping falls into the collection box 13 through the punching hole 32 and the guide plate 12 for collection, reducing the possibility of waste affecting the working environment. The support plate 3 provides stable support for the sheet metal parts, reducing the possibility of deformation of the sheet metal parts during the stamping process, which helps to improve the punching quality of the sheet metal parts.

[0041] The implementation principle of the positioning device for stamping sheet metal parts for air conditioners in this embodiment is as follows: Before punching the sheet metal parts, the distance between the two clamping strips 41 is adjusted according to the length of the sheet metal parts. The operator pushes the sheet metal parts onto the support plate 3, and one side of the sheet metal parts abuts against the abutment rod 10 to achieve limiting.

[0042] Rotating the handle 49 causes the clamping plate 42 to move downwards and press the sheet metal part firmly. The moving plate 2 moves intermittently. When the moving plate 2 and the support plate 3 stop moving, the stamping device stamps the sheet metal part. The support plate 3 provides stable support for the sheet metal part, reducing the possibility of deformation during the stamping process and helping to improve the punching quality of the sheet metal part.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
