Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping device for plates with through holes. Background Technology

[0002] In industrial production, perforated plates are special types of plates with pre-processed through holes, such as perforated plates and round hole mesh.

[0003] Some mechanical equipment requires the installation of perforated plates during assembly to enable functions such as ventilation or material filtration. Before assembly, the perforated plates need to be cut, welded, or drilled to obtain the required shape. The traditional method involves placing the perforated plate on an operating platform, exposing the portion to be cut, and then manually holding the plate down to prevent misalignment while using a hand-held cutting machine. However, during the cutting process, the operator may experience unstable pressure on the plate due to the force applied by the cutting machine, resulting in insufficient cutting precision. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A clamping device for a plate with through holes is provided, including a mounting base. Two slides for mounting the plate are horizontally and linearly slidably arranged on the mounting base. Each slide is provided with a positioning post for passing through the through hole of the plate. Each slide is linearly and linearly slidably arranged with a clamping plate for cooperating with the slides to clamp the plate. The mounting base is provided with a first driving member for driving the two slides to move in opposite directions, and the slides are provided with a second driving member for driving the clamping plate to move.

[0007] Furthermore, the slide includes a slide plate and a rotating plate. The slide plate is linearly slidably connected to the mounting base and is driven by the first driving member. The rotating plate is rotatably mounted on the slide plate. The clamping plate is slidably connected to the rotating plate in a direction perpendicular to the rotating plate and is driven by the second driving member. The slide plate is provided with a third driving member for driving the rotating plate to rotate to adjust the welding angle of the two plates. The positioning post is mounted on the rotating plate.

[0008] Furthermore, the outer wall of the positioning post is conical, and the positioning post is slidably mounted on the rotating plate along the thickness direction of the rotating plate. The rotating plate is provided with a groove for the positioning post to slide, and the rotating plate is provided with an adjusting member for driving the positioning post to move so as to adjust the length of the positioning post extending out of the groove.

[0009] Furthermore, the adjusting component includes a stud, which is threaded into the slide groove. One end of the stud is fixedly connected to the positioning pin, and the other end of the stud extends out of the rotating plate and is connected to the first handle.

[0010] Furthermore, the side of the clamping plate near the rotating plate is provided with a friction pad for pressing against the plate.

[0011] Furthermore, the mounting base is provided with a baffle to prevent processing debris from the sheet metal from falling onto the first drive member.

[0012] Furthermore, the middle part of the baffle is higher than the two sides to form an inclined guide surface at the top of the baffle, and a collection groove for collecting processing debris of the plate is provided on the mounting base.

[0013] The beneficial effects of this utility model are as follows: When cutting or drilling plates, two slides can be moved according to the length of the plate so that both ends of the plate can be installed on the two slides respectively, and two positioning pins can be inserted into the through holes of the plate. Then, two clamping plates move and cooperate with the two slides to clamp both ends of the plate, which can fix the plate for cutting.

Detailed Implementation

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a clamping device for plates with through holes, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a mounting base 1, on which two slide blocks 2 for mounting plates are horizontally and linearly slidably mounted. Each slide block 2 has a positioning post 3 for passing through a through hole in the plate, and each slide block 2 has a clamping plate 4 for cooperating with the slide blocks 2 to clamp the plate. The mounting base 1 is provided with a first driving member 5 for driving the two slide blocks 2 to move in opposite directions, and the slide blocks 2 are provided with a second driving member 6 for driving the clamping plate 4 to move.

[0021] When cutting or drilling plates, the two slide blocks 2 can be moved according to the length of the plate so that both ends of the plate can be mounted on the two slide blocks 2 respectively, and the two positioning posts 3 can be inserted into the through holes of the plate. Then, the two clamping plates 4 move and cooperate with the two slide blocks 2 to clamp both ends of the plate, thus fixing the plate in place for cutting. This clamping device for plates with through holes eliminates the need for manual pressing of the plate during cutting. The use of positioning posts 3 and clamping plates 4 for fixation improves the installation stability of the plate during cutting and enhances the cutting accuracy.

[0022] In addition, when welding two plates, the two plates to be welded can be installed on two slide blocks 2 respectively, and the two positioning pins 3 can be inserted into the through holes of the two plates respectively. Then, the plates can be clamped and fixed by the clamping plate 4 in conjunction with the slide blocks 2. Then, the two slide blocks 2 can be moved to make the two plates come into contact so that welding can be performed.

[0023] Specifically, the slide block 2 includes a slide plate 21 and a rotating plate 22. The slide plate 21 is linearly slidably connected to the mounting base 1 and is driven by the first driving member 5. The rotating plate 22 is rotatably mounted on the slide plate 21, and the clamping plate 4 is slidably connected to the rotating plate 22 in a direction perpendicular to the rotating plate 22 and is driven by the second driving member 6. A third driving member 7 is provided on the slide plate 21 to drive the rotating plate 22 to adjust the welding angle of the two plates. The positioning post 3 is provided on the rotating plate 22.

[0024] In this embodiment, the two cut plates are respectively mounted on two rotating plates 22. Rotating the rotating plates 22 can adjust the welding angle of the two plates, which improves the processing versatility of the equipment.

[0025] Reference Figure 4The outer wall of the positioning post 3 is conical, and the positioning post 3 is slidably disposed on the rotating plate 22 along the thickness direction of the rotating plate 22. The rotating plate 22 is provided with a groove 221 for the positioning post 3 to slide, and the rotating plate 22 is provided with an adjusting member 8 for driving the positioning post 3 to move to adjust the length of the positioning post 3 extending out of the groove 221.

[0026] In this embodiment, by moving the positioning post 3 and adjusting the length of the positioning post 3 extending out of the slide groove 221, the maximum outer diameter of the portion of the positioning post 3 extending out of the slide groove 221 can be adjusted so that it can adapt to the through hole size on various plates.

[0027] Specifically, the adjusting component 8 includes a stud 81, which is threaded into the slide groove 221. One end of the stud 81 is welded and fixed to the positioning post 3, and the other end of the stud 81 extends out of the rotating plate 22 and is welded with a first handle.

[0028] In this embodiment, a threaded hole with a size that matches the stud 81 is provided on the inner bottom wall of the slide groove 221. Rotating the stud 81 can adjust the length of the positioning pin 3 extending out of the slide groove 221.

[0029] Furthermore, a friction pad 9 for pressing against the sheet material is provided on the side of the clamping plate 4 near the rotating plate 22.

[0030] In this embodiment, the friction force on the plate is increased by pressing the plate with the friction pad 9, which further improves the stability of the plate on the rotating plate 22.

[0031] In this embodiment, the first driving component 5 includes a bidirectional screw, which is rotatably mounted on the mounting base 1. Two sliding plates 21 are threadedly connected to the two threaded sections of the bidirectional screw, respectively. One end of the bidirectional screw extends out of the mounting base 1 and is connected to a second handle. Rotating the bidirectional screw drives the two sliding plates 21 to move in opposite directions. The second driving component 6 includes a first driving cylinder, which is mounted on the rotating plate 22, and its piston rod is bolted to the clamping plate 4. The third driving component 7 includes a second driving cylinder, which is rotatably mounted on the side wall of the sliding plate 21, and its piston rod is rotatably connected to the rotating plate 22.

[0032] Furthermore, the mounting base 1 is provided with a baffle 10 to prevent processing debris from the plate 10 material from falling onto the first drive member 5.

[0033] In this embodiment, the baffle 10 is disposed on the mounting base 1, and a gap is formed between the slide plate 21 and the rotating plate 22 for the baffle 10 to pass through. During the processing, the baffle 10 blocks the processing debris of the plate 10 material, thus preventing the debris from adhering to the bidirectional screw and affecting the movement of the slide plate 21.

[0034] Furthermore, the middle part of the baffle 10 is higher than the two sides to form an inclined guide surface on the top of the baffle 10, and a collection groove 11 for collecting processing debris of the plate is provided on the mounting base 1.

[0035] In this embodiment, the processing debris falling on the baffle 10 can move down along the guide surface and then fall into the collection groove 11 below for unified collection.

[0036] The implementation principle of a clamping device for through-hole plates according to an embodiment of this application is as follows: When cutting the plate or drilling, two slide blocks 2 can be moved according to the length of the plate so that both ends of the plate can be installed on the two slide blocks 2 respectively, and two positioning posts 3 are inserted into the through holes of the plate. Then, two clamping plates 4 move and cooperate with the two slide blocks 2 to clamp both ends of the plate, thereby fixing the plate for cutting. This clamping device for through-hole plates eliminates the need for manual pressing of the plate during cutting. The use of positioning posts 3 and clamping plates 4 for fixation improves the installation stability of the plate during cutting and enhances the cutting accuracy.
