Description

Technical Field

[0001] This utility model relates to the field of punching fixtures, and in particular to a skylight opening punching fixture. Background Technology

[0002] In the processing of building panels, automotive interior panels, and other sheet metal products, sunroof opening punching is a common forming process. Specialized fixtures are required to precisely position and stably fix the sheet metal, ensuring the flatness and dimensional accuracy of the punched edges. With increasing demands for mass production, the automation level of the punching fixtures and processing safety have become key factors affecting production efficiency.

[0003] However, traditional skylight opening punching fixtures have problems in practical applications: First, the positioning and clamping accuracy is insufficient. Traditional fixtures mostly rely on manual clamping, which is not only slow in manually rotating the clamping parts, but also makes it difficult to ensure the consistency of the plate positioning; manual clamping depends on the operator's experience, and clamping too loosely can easily cause displacement, while clamping too tightly can easily cause the plate to deform.

[0004] Secondly, the operation is unsafe and the conveying efficiency is poor. In traditional punching operations, workers need to manually insert the sheet metal from outside the punching machine into the working area. During the operation, the hands are likely to come into contact with the punching die, which poses a risk of mechanical injury. At the same time, the manual conveying speed is slow, which seriously restricts the efficiency of mass production.

[0005] These problems make it difficult for traditional punching fixtures to meet the demands of efficient, high-precision, and high-safety mass production. Utility Model Content

[0006] The purpose of this invention is to provide a skylight opening punching fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a skylight opening punching fixture, including a support platform, a movable conveying mechanism on the support platform, a punching fixture on the movable conveying mechanism, and automatic clamping mechanisms on both sides of the punching fixture.

[0008] In a preferred embodiment of this utility model, the mobile conveying mechanism includes support rods, a pair of support rods respectively disposed on both sides of a support platform, and a guide rail on each support rod. Bearing transmission components are provided at both ends of one support rod. A support plate is provided on the outer side of the support platform near the bearing transmission components. A motor is mounted on the support plate, and a reducer is connected to the output end of the motor. A transmission rod is connected to the output end of the reducer. The transmission rod passes through one of the bearing transmission components, and a transmission rod is movably disposed within the bearing transmission component on the other side. Transmission wheels are provided on both transmission rods, and a transmission belt is fitted onto the pair of transmission wheels. The punching fixture is disposed on the guide rail, and a pair of guide frames are provided below the punching fixture. The guide frames are tightly fitted and inserted into the guide rail, and are movably disposed on the guide rail. A connecting member is provided below the punching fixture near the motor, and the connecting member is connected to the transmission belt.

[0009] In a preferred embodiment of this utility model, the automatic clamping mechanism includes a positioning frame and a guide plate. The positioning frame is equipped with a second motor, and the output end of the second motor is connected to a lead screw. The lead screw is movably disposed between the punching fixture and the positioning frame. One end of the guide plate is threadedly connected to the lead screw. Guide sleeves are provided on both sides of the guide plate. A guide rod is provided on the punching fixture, and the guide sleeves are movably disposed on the guide rod. A clamping and positioning component is connected to one side of the guide plate.

[0010] As a preferred embodiment of this utility model, the punching tool table is provided with a waste discharge port, and the support table is provided with a waste collection bin.

[0011] As a preferred embodiment of the present invention, the punching fixture is provided with a contour positioning component, which is located around the waste discharge port.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. The automatic clamping mechanism is driven by a motor and a lead screw, which drives the guide plate to move precisely along the guide rod to avoid displacement during the punching process. It can also be adapted to different thickness plates by adjusting the number of motor rotations, preventing dimensional deviations and plate deformation caused by excessively loose or tight clamping, and significantly improving the flatness and dimensional accuracy of the punching edge.

[0014] 2. The mobile conveyor mechanism drives the punching fixture table to move automatically along the guide rail via motor 1 and conveyor belt, realizing the automated conveying of the sheet metal from the initial position to the punching station. There is no need for manual insertion of the sheet metal into the working area of ​​the punching machine, avoiding hands from approaching the punching mold, greatly reducing the risk of mechanical injury and improving operational safety.

[0015] 3. Compared to screw and rack drive, the conveyor belt drives the punching fixture table, which is less expensive and only requires replacement of the conveyor belt when it is damaged, preventing production from being interrupted for a long time due to maintenance.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] This utility model provides a technical solution: a skylight opening punching fixture, such as... Figure 1 As shown, it includes a support platform 1, a mobile conveying mechanism 2 on the support platform 1, a punching fixture 3 on the mobile conveying mechanism 2, and automatic clamping mechanisms 4 on both sides of the punching fixture 3.

[0024] like Figures 2-4As shown, the mobile conveying mechanism 2 includes support rods 201, a pair of support rods 201 respectively located on both sides of the support platform 1, and guide rails 202 provided on the support rods 201. Bearing transmission components 203 are provided at both ends of one support rod 201. A support plate 204 is provided on the outer side of the support platform 1 near the bearing transmission components 203. A motor 205 is provided on the support plate 204. A reducer 206 is connected to the output end of the motor 205, and a transmission rod 207 is connected to the output end of the reducer 206. The transmission rod 207 passes through one of the bearings. The transmission component 203 has a transmission rod 208 movably installed inside the bearing transmission component 203 on the other side. The transmission rod 207 and the transmission rod 208 are equipped with transmission wheels 209. A transmission belt 210 is sleeved on a pair of transmission wheels 209. The punching fixture 3 is set on the guide rail 202. A pair of guide frames 211 are provided below the punching fixture 3. The guide frames 211 are tightly fitted and inserted into the guide rail 202, and the guide frames 211 are movably set on the guide rail 202. A connection is provided on the side of the punching fixture 3 near the motor 205.

[0025] like Figure 5 As shown, the automatic clamping mechanism 4 includes a positioning frame 401 and a guide plate 402. The positioning frame 401 is equipped with a second motor 403. The output end of the second motor 403 is connected to a lead screw 404. The lead screw 404 is movably disposed between the punching fixture 3 and the positioning frame 401. One end of the guide plate 402 is threadedly connected to the lead screw 404. Guide sleeves 405 are provided on both sides of the guide plate 402. The punching fixture 3 is equipped with a guide rod 406. The guide sleeves 405 are movably disposed on the guide rod 406. A clamping and positioning component 407 is connected to one side of the guide plate 402.

[0026] like Figure 1 , Figure 2 As shown, the punching fixture 3 has a waste discharge port 301, and the support table 1 has a waste collection bin 101.

[0027] like Figure 2 As shown, the punching fixture 3 is provided with a contour positioning component 302, which is located around the waste discharge port 301.

[0028] In practice, the sheet metal to be punched is placed in the area enclosed by the profile positioning part 302. The gap between the edge of the sheet metal and the profile positioning part 302 does not exceed 1mm. The profile positioning part 302 is used to initially position the sheet metal to ensure that the punching area of ​​the sheet metal corresponds to the waste discharge port 301.

[0029] Motor 403 is started, driving the lead screw 404 to rotate forward. Under the threaded transmission of the lead screw 404, the guide plate 402 moves along the guide rod 406 towards the sheet metal. The cooperation between the guide sleeve 405 and the guide rod 406 ensures the linearity of the guide plate 402's movement, preventing offset during clamping. As the guide plate 402 moves, the clamping positioning component 407 gradually approaches the sheet metal until it is in close contact with the side of the sheet metal. At this point, the torque control of motor 403 causes the clamping positioning component 407 to fix the sheet metal with a clamping force of 300-500N. During clamping, the clamping force can be monitored in real time by a sensor to ensure that the sheet metal does not shift during punching, and the displacement does not exceed 0.1mm. If the sheet metal thickness is different, the clamping position of the clamping positioning component 407 can be adjusted by adjusting the number of rotations of motor 403 to accommodate sheet metal of different thicknesses.

[0030] After clamping, motor 205 starts, and its power is reduced by reducer 206 and transmitted to transmission rod 207. Transmission rod 207 drives transmission wheel 209 to rotate. Through the transmission belt 210, transmission wheel 209 and transmission rod 208 on the other side rotate synchronously, thereby driving guide frame 211 under punching fixture 3 to move smoothly along guide rail 202. The tight fit between guide frame 211 and guide rail 202 ensures the stability of punching fixture 3 during movement, and the horizontal deviation of punching fixture 3 does not exceed 0.2mm. When punching fixture 3 moves to the punching position, motor 205 stops working, and the punching die moves downward under external power to perform skylight opening punching operation on the sheet metal. The waste generated by punching falls into waste collection bin 101 through waste discharge port 301 under gravity, realizing automatic waste collection.

[0031] After punching is completed, the punching die moves upward to reset, and motor 1 205 reverses, driving the punching fixture 3 back to its initial position along guide rail 202. Subsequently, motor 2 403 reverses, and lead screw 404 drives guide plate 402 and clamping positioning component 407 to move away from the sheet metal, releasing the clamp on the sheet metal. The operator removes the punched workpiece, cleans the waste material in waste collection bin 101, completing one punching cycle and preparing for the next punching operation.
