A clamping device for processing appliance cabinet cover

Abstract

This utility model discloses a clamping device for processing electrical appliance enclosure covers, relating to the field of electrical appliance enclosure cover processing technology. The clamping device includes a base plate, with a limiting mechanism above the base plate: a clamping assembly including a support column fixedly installed above the base plate. A downward-pressing electric push rod is fixedly installed at the top of the support column. A connecting block is fixedly installed at the center of the base plate and the bottom end of the downward-pressing electric push rod. When the rubber column contacts the edge of the enclosure cover, the enclosure cover generates resistance against the rubber column. At this time, although the sleeve and drive shaft continue to rotate, the limiting rod cannot be driven to rotate further due to the obstruction of the rubber column. During this process, the rubber layer restricts the relative sliding between the limiting rod, sleeve, and drive shaft through friction, allowing the rubber column to continuously apply balanced pressure to the four corners of the enclosure cover, pushing the enclosure cover towards the center, and ultimately precisely limiting it at the center of the clamping assembly, achieving rapid positioning.

Description

Technical Field

[0001] This utility model relates to the field of electrical appliance box cover processing technology, specifically a clamping device for processing electrical appliance box covers. Background Technology

[0002] Metal materials are widely used in electrical enclosures where structural stability is required due to their high strength and impact resistance, especially in industrial equipment and outdoor electrical appliances. In the production process of electrical enclosures, fixtures are key auxiliary equipment, and their role is involved in multiple stages such as cutting, stamping, welding, drilling, assembly, and surface treatment, directly affecting product quality, production efficiency, and operational safety.

[0003] The existing utility model patent with publication number CN222711278U discloses a metal sheet welding fixture, including a base and a fixture unit. The fixture unit is slidably connected to both ends of the base. The fixture unit includes a slide, a support, a vertical movement power mechanism, and a placement frame. The slide is slidably connected to the base, and the support is fixedly connected to the slide. The vertical movement power mechanism is fixedly connected to the support. The placement frame is located between the support and the slide and is fixedly connected to the output end of the vertical movement power mechanism. The slide has multiple rotating wheels, and the bottom plate of the placement frame has multiple through slots corresponding to the rotating wheels. The placement frame has a pressure plate structure. This metal sheet welding fixture facilitates the placement of metal sheets within the fixture.

[0004] The aforementioned clamping structure restricts the position of the plate by clamping the upper and lower sides of both ends of the plate with clamping components on both sides. In this way, the angle of the plate cannot be adjusted quickly, and the two sides of the plate are located inside the clamping structure. The clamping operation needs to be repeated repeatedly during the processing, which is very inconvenient. At the same time, the clamping structure has no limit on the two sides, so the position of the plate cannot be determined quickly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a clamping device for processing appliance cabinet covers, which solves the problems of inability to quickly position the device and the need for repeated clamping operations during processing due to the clamping structure wrapping around the edge of the sheet metal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A clamping device for processing an electrical appliance cabinet cover includes a base plate, and a limiting mechanism is provided above the base plate.

[0007] The clamping assembly includes a support column fixedly installed above a base plate. A downward-pressing electric actuator is fixedly installed at the top of the support column. A connecting block is fixedly installed at the center of the base plate and the bottom end of the downward-pressing electric actuator.

A movable frame is movably installed below the connecting block at the bottom end of the downward-pressing electric actuator. A limit frame is movably installed above the connecting block at the center of the base plate. A rubber ring is fixedly installed at one end of the movable frame and the limit frame. A miniature electric actuator is fixedly installed above the base plate. A limit block is fixedly installed at the movable end of the miniature electric actuator.

[0008] A positioning component, positioned above the base plate, is used to quickly lock the case cover in the center of the clamping component.

[0009] Preferably, the positioning component includes a housing fixedly installed above the base plate, a sleeve inserted at the top of the housing, a drive shaft inserted inside the sleeve, a drive gear fixedly installed on the drive shaft and the outside of the sleeve, a drive motor fixedly installed on one side of the housing, a drive gear fixedly installed on the outside of the drive motor shaft, a limit rod movably installed on the drive shaft and the top of the sleeve, and a rubber column fixedly installed on the outside of the limit rod.

[0010] Preferably, the connecting block is a cylindrical structure with a disc-shaped protrusion at one end. The pressure bearing is fixedly installed on one side of the disc-shaped protrusion of the connecting block and the top of the connecting block. The movable frame and the limiting frame are rotatably connected to the connecting block at the bottom of the lower electric push rod and the connecting block at the center of the base plate through the pressure bearing and the ball bearing, respectively.

[0011] Preferably, the bottom of the limiting frame is provided with notches distributed in an "X" shape and fitting into the limiting block, and the limiting block is installed in an "X" shape above the base plate by a miniature electric actuator.

[0012] Preferably, the positioning component is installed in an "X" shape above the base plate with the center of the connecting block as the reference, the sleeve and the outer shell are rotatably connected, and the drive shaft and the sleeve are rotatably connected.

[0013] Preferably, the transmission shaft and the transmission gear and drive gear on the outside of the sleeve mesh with each other, the top of the transmission shaft and the outside of the sleeve are provided with a rubber anti-slip layer, and the limiting rod is rotatably connected to the transmission shaft and the sleeve.

[0014] Beneficial effects

[0015] This utility model provides a clamping device for processing appliance cabinet covers. Compared with the prior art, it has the following advantages:

[0016] (1) The clamping device for processing the electrical enclosure cover, through the setting of the drive shaft and the sleeve, the positioning components are distributed in an "X" shape with the center of the device as the reference. When working, the drive motor starts and drives the drive gear to rotate. The drive gear meshes with the drive shaft and the drive gear on the outside of the sleeve, thereby driving the drive shaft and the sleeve to rotate in the opposite direction under the limitation of the outer shell. The limiting rod is connected to the sleeve and the top surface of the drive shaft through the rubber layer. Initially, it will rotate synchronously with the sleeve and the drive shaft, and the rubber column on its outside will move closer to the edge of the enclosure cover. When the rubber column contacts the edge of the housing cover, the housing cover generates resistance to the rubber column. At this time, although the sleeve and drive shaft continue to rotate, the limiting rod cannot be driven to rotate due to the obstruction of the rubber column. During this process, the rubber layer restricts the relative sliding between the limiting rod, sleeve, and drive shaft through friction, so that the rubber column continuously applies balanced pressure to the four corners of the housing cover, pushing the housing cover to move towards the center, and finally accurately limiting it to the center of the clamping assembly, achieving rapid positioning. After positioning is completed, the drive motor reverses, driving the drive shaft and sleeve to rotate in the opposite direction. The limiting rod is reset with the reverse rotation, away from the edge of the housing cover, avoiding interference with the housing cover during subsequent angle adjustments.

[0017] (2) The clamping device for processing the appliance cabinet cover, through the setting of the movable frame and the limiting frame, when the clamping component is working, the downward electric push rod drives the bottom connecting block to move down, and the movable frame below the connecting block moves down accordingly, cooperating with the limiting frame above the connecting block in the center of the base plate. The rubber rings at the ends of the two clamp the inner area of ​​the cabinet cover, so that the edge of the cabinet cover is always exposed, which is convenient for processing. When the angle needs to be adjusted, the mini electric push rod retracts, and the limiting block at its movable end disengages from the bottom notch of the limiting frame. The movable frame and the limiting frame are rotatedly connected to the corresponding connecting blocks through pressure bearings and ball bearings, respectively, so that the cabinet cover can be easily rotated manually. Since the limiting rod has reversed and moved away from the cabinet cover after positioning, it will not hinder the rotation process. After adjustment, the mini electric push rod extends to make the limiting block re-embed into the notch to fix the limiting frame, so that processing can continue without repeated clamping, effectively solving the problem of repeated clamping.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a clamping device for processing an electrical appliance box cover includes a base plate 1, and a limiting mechanism 2 is provided above the base plate 1.

[0025] The clamping assembly 21 includes a support column 211 fixedly installed above the base plate 1. A downward electric actuator 212 is fixedly installed at the top of the support column 211. A connecting block 213 is fixedly installed at the center of the base plate 1 and the bottom end of the downward electric actuator 212. A pressure bearing 214 is fixedly installed on the outer side and bottom end of the connecting block 213. A movable frame 215 is movably installed below the connecting block 213 at the bottom end of the downward electric actuator 212. A limit frame 216 is movably installed above the connecting block 213 at the center of the base plate 1. A rubber ring 217 is fixedly installed at one end of the movable frame 215 and the limit frame 216. A miniature electric actuator 218 is fixedly installed above the base plate 1. The movable end of the push rod 218 is fixedly installed with a limiting block 219. The connecting block 213 is a cylindrical structure with a disc-shaped protrusion at one end. The pressure bearing 214 is fixedly installed on one side of the disc-shaped protrusion of the connecting block 213 and the top of the connecting block 213. The movable frame 215 and the limiting frame 216 are rotatably connected to the connecting block 213 at the bottom of the lower electric push rod 212 and the connecting block 213 at the center of the base plate 1 through the pressure bearing 214 and the ball bearing, respectively. The bottom of the limiting frame 216 is provided with notches distributed in an "X" shape and fitted with the limiting block 219. The limiting block 219 is installed in an "X" shape above the base plate 1 through the miniature electric push rod 218.

[0026] Specifically, the connection point between the support column 211 and the base plate 1 is located on the rear side of the connecting block 213, which can prevent the vertical part of the support column 211 from blocking the rotation of the box cover when the box cover rotates. The pressure bearing 214 can bear the axial load when the electric push rod 212 drives the connecting block 213 and the movable frame 215 to move downward and clamp the box cover with the limiting frame 216. At the same time, it allows the movable frame 215 and the limiting frame 216 to rotate. Thus, after the miniature electric push rod 218 retracts and drives the limiting block 219 to separate from the limiting frame 216, the user can manually adjust the rotation angle of the box cover.

[0027] Positioning component 22, disposed above base plate 1, is used to quickly restrain the box cover at the center of clamping component 21. Positioning component 22 includes a housing 221 fixedly mounted above base plate 1. A sleeve 222 is inserted through the top of housing 221. A drive shaft 223 is inserted through the inside of sleeve 222. A drive gear 224 is fixedly mounted on the outside of drive shaft 223 and sleeve 222. A drive motor 225 is fixedly mounted on one side of housing 221. A drive gear 226 is fixedly mounted on the outside of the shaft of drive motor 225. The drive shaft 223 and the top of sleeve 222 are movably mounted in a limited manner. Positioning rod 228, rubber column 229 is fixedly installed on the outside of positioning rod 228, positioning component 22 is installed in an "X" shape above base plate 1 with the center of connecting block 213 as reference, sleeve 222 and outer shell 221 are rotatably connected, drive shaft 223 and sleeve 222 are rotatably connected, drive gear 224 and drive gear 226 on the outside of drive shaft 223 and sleeve 222 mesh with each other, rubber anti-slip layer is provided on the top of the outside of drive shaft 223 and sleeve 222, and positioning rod 228 is rotatably connected to drive shaft 223 and sleeve 222.

[0028] Specifically, the outer casing 221 can restrict the position of the sleeve 222 and the drive shaft 223. The drive motor 225 drives the drive gear 226 to rotate. The drive gear 226 and the drive gear 224 mesh with each other. After the drive motor 225 starts, the sleeve 222 and the drive shaft 223 drive the limiting rod 228 to rotate in opposite directions, so that the rubber post 229 at one end of the limiting rod 228 contacts the outside of the box cover, causing the box cover to move. Since the positioning components 22 are distributed in an "X" shape, they can apply pressure to the box cover at the four corners of the box cover, thereby restricting the box cover to the center of the clamping component 21. After the rubber post 229 contacts the edge of the box cover, the sleeve 222 and the drive shaft 223 continue to rotate. The limiting rod 228 will rotate relative to the sleeve 222 and the drive shaft 223 under the restriction of the rubber post 229.

[0029] Specifically, the model of the downward electric actuator 212 is YMD-501B, the model of the miniature electric actuator 218 is GWLSA-T8-24-30-75-30, and the model of the drive motor 225 is MS6. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] During operation, firstly, the electrical enclosure cover is placed above the limiting frame 216. Then, the positioning assembly 22 starts working, and the drive motor 225 drives the drive gear 226 to rotate. Because the drive gear 226 meshes with the drive shaft 223 and the drive gear 224 on the outside of the sleeve 222, the sleeve 222 and the drive shaft 223 rotate in opposite directions under the limiting effect of the outer casing 221, thereby driving the top limiting rod 228 to rotate. The rubber post 229 on the outside of the limiting rod 228 contacts the edge of the enclosure cover. Since the positioning assembly 22 is distributed in an "X" shape with the center of the connecting block 213 as the reference, the rubber post 229 applies pressure from the four corners of the enclosure cover, pushing it to the center position of the clamping assembly 21. At this time, the limiting rod 228 rotates relative to the drive shaft 223 and the sleeve 222 under the restriction of the rubber post 229. After positioning is completed, the clamping assembly 21 starts to work. The downward electric push rod 212 at the top of the support column 211 is activated, which drives the connecting block 213 at the bottom to move downward. The movable frame 215 below the connecting block 213 moves downward accordingly and cooperates with the limiting frame 216 above the connecting block 213 in the center of the base plate 1. The rubber ring 217 at one end of the movable frame 215 and the limiting frame 216 clamps the box cover. At the same time, the miniature electric push rod 218 above the base plate 1 extends, and the limiting block 219 at its movable end is embedded in the "X"-shaped notch at the bottom of the limiting frame 216 to fix the limiting frame 216 and prevent it from rotating. If the angle of the box cover needs to be adjusted during processing, the miniature electric actuator 218 retracts, and the limiting block 219 disengages from the notch. Since the movable frame 215 and the limiting frame 216 are rotatably connected to the bottom connecting block 213 of the lower electric actuator 212 and the center connecting block 213 of the base plate 1 through the pressure bearing 214 and the ball bearing respectively, the box cover can be manually rotated to adjust the angle. After the adjustment is completed, the miniature electric actuator 218 extends again, and the limiting block 219 re-embeds into the notch to fix the limiting frame 216, and the processing operation continues.
