Description

Technical Field

[0001] This utility model relates to the field of boiler parts processing technology, specifically a clamping device for boiler parts production. Background Technology

[0002] Boiler parts processing refers to the process of manufacturing various parts required by a boiler from raw materials (such as steel plates, steel pipes, alloy materials, etc.) through a series of mechanical manufacturing processes (such as casting, forging, cutting, welding, machining, heat treatment, etc.) according to the boiler's design drawings, technical standards, and performance requirements. Current boiler parts production requires the use of clamping devices to hold the boiler parts, which facilitates subsequent grinding or polishing processing.

[0003] The utility model patent application with publication number "CN219005693U" discloses a clamping device for boiler parts production, which mainly consists of a base, a workbench, a mounting frame, an electric telescopic rod, and clamping components. This technical solution uses the clamping components and the opening of the electric telescopic rod to move the two sets of clamping components inward, thereby clamping the boiler parts.

[0004] The clamping device for boiler parts production disclosed in the aforementioned document has the following defects: Although the clamping device is equipped with a perforated worktable and a waste bin for collecting debris, the table surface of the perforated worktable is made up of through holes with solid gaps between them. This causes some debris to be unable to fall directly into the waste bin through the through holes, but instead accumulates on the solid area of ​​the table surface. As a result, the device cannot achieve fully automatic collection of debris, and ultimately still requires manual cleaning intervention. This not only reduces the working efficiency of the equipment, but also increases the maintenance burden on the operators. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping device for boiler parts production, which solves the problem that debris cannot fall directly into the waste bin through the through hole, but instead accumulates on the solid area of ​​the table, making it impossible for the device to achieve fully automatic collection of debris. Ultimately, manual cleaning intervention is still required, which not only reduces the working efficiency of the equipment, but also increases the maintenance burden on the operators.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a clamping device for boiler parts production, comprising a workbench with two sets of clamping structures at the upper end. An installation groove is formed at the upper end of the workbench, and a guide plate is fixedly installed inside the installation groove. A screening plate is fixedly installed at the upper end of the guide plate. The middle of the guide plate slopes downward to form two inclined surfaces, and a chip discharge port is formed in the middle of the guide plate. The chip discharge port is located at the bottom of the two inclined surfaces. Two sets of vibration components are arranged inside the installation groove, both sets of vibration components being located at the lower end of the corresponding inclined surface of the guide plate and in contact with the guide plate, used to drive the guide plate to vibrate.

[0008] Furthermore, the vibration assembly includes a connecting shaft rotatably connected inside the mounting groove. Multiple cams that contact the inclined surface of the guide plate are fixedly mounted on the outer side of the connecting shaft. One end of the connecting shaft passes through the workbench and is equipped with a first synchronous pulley. The first synchronous pulleys in the two sets of vibration assemblies are connected by a synchronous belt. One end of one of the connecting shafts is also equipped with a second synchronous pulley. A motor is provided on the outer side of the workbench. A third synchronous pulley is installed at the output end of the motor. The third synchronous pulley is connected to the second synchronous pulley by a synchronous belt.

[0009] Furthermore, the clamping structure includes a movable plate and an electric push rod fixedly installed in the middle of the movable plate. A clamping block is installed at the output end of the electric push rod. A slide rail is provided at the upper end of the worktable. A slider that is slidably connected to the slide rail is provided at the lower end of the movable plate. A plurality of positioning holes are also provided at the upper end of the worktable. A first connecting plate is provided on the outer side of the movable plate. A locking bolt that is threadedly connected to any of the positioning holes is installed in the middle of the first connecting plate.

[0010] Furthermore, a limiting frame is provided at the upper end of the workbench, and the screening plate is located inside the limiting frame.

[0011] Furthermore, a protective cover is fixedly installed on one side of the workbench, and an installation port is opened on the other side. A collection box located below the guide plate is slidably connected inside the installation port, and a handle is fixedly installed on the outside of the collection box.

[0012] Furthermore, a rectangular block is provided on the outer side of the collection box, and a limiting hole is provided at the upper end of the rectangular block. A side plate is provided on the outer side of the workbench, and a mounting hole is provided in the middle of the side plate. A connecting rod is slidably connected inside the mounting hole. A horizontal plate is fixedly installed at the upper end of the connecting rod, and a second connecting plate is fixedly installed at the lower end. A triangular block that mates with the limiting hole is provided at the lower end of the second connecting plate. A spring is sleeved on the outer side of the connecting rod. The upper end of the spring is fixedly connected to the lower end of the side plate, and the lower end is fixedly connected to the upper end of the second connecting plate.

[0013] This utility model has the following beneficial effects:

[0014] (1) By starting the motor, the output shaft of the motor drives the third synchronous wheel to rotate. The third synchronous wheel drives the second synchronous wheel to rotate through the synchronous belt. The second synchronous wheel drives the connecting shaft connected to it to rotate. The connecting shaft then transmits power to another set of first synchronous wheels through the first synchronous wheel and synchronous belt at its other end, driving the two connecting shafts to rotate synchronously. Multiple cams on each connecting shaft rotate accordingly. During the rotation, the protruding part of the cam periodically pushes up the inclined surface of the guide plate, causing it to generate high-frequency micro-vibration. This vibration is transmitted to the screening plate, causing it to vibrate together. The debris generated during processing falls onto the screening plate. The vibration of the screening plate accelerates the debris from falling through its mesh and prevents the debris from accumulating and adhering on the plate surface. The debris falling onto the inclined surface of the guide plate slides downward along the inclined surface under the action of continuous vibration and its own gravity, and finally all of them are collected and discharged through the chip discharge port. By using the screening plate and the vibration component together, the residue of debris on the processing table can be eliminated, reducing the reliance on manual cleaning intervention in the later stage, thereby significantly improving the continuous operation efficiency of the equipment.

[0015] (2) This utility model pushes the moving plate so that the moving plate slides on the slide rail of the worktable through the slider at its lower end, thereby adjusting the two sets of clamping structures to a suitable distance. Then, the locking bolt is screwed into the nearest positioning hole to fix the position of the moving plate. Subsequently, the boiler accessories are placed on the screening plate and positioned between the two clamping blocks. The electric push rod is started, and the output end of the electric push rod extends to push the clamping blocks toward the boiler accessories until the two clamping blocks are in close contact and press the accessories to complete the clamping. In this process, the clamping distance is adjusted through the flexible cooperation of the slider and the slide rail, which can quickly adapt to boiler accessories of different sizes and shapes. The universal electric clamping force is combined with the freely positioning locking. The operator only needs to manually push to make a rough adjustment of the positioning, and then use the locking bolt to achieve rigid fixation. Finally, the electric push rod completes the precise and stable clamping.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] This utility model discloses a clamping device for boiler parts production, including a workbench 1, two sets of clamping structures 2 are provided on the upper end of the workbench 1, an installation groove is provided on the upper end of the workbench 1, a guide plate 4 is fixedly installed inside the installation groove, a screening plate 5 is fixedly installed on the upper end of the guide plate 4, and two sets of vibration components are provided inside the installation groove.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment discloses an implementation method for the clamping structure 2:

[0029] The clamping structure 2 includes a movable plate 201 and an electric push rod 202 fixedly installed in the middle of the movable plate 201. A clamping block 203 is installed at the output end of the electric push rod 202. A slide rail 102 is provided at the upper end of the worktable 1. A slider 204 that is slidably connected to the slide rail 102 is provided at the lower end of the movable plate 201. A plurality of positioning holes 103 are also provided at the upper end of the worktable 1. A first connecting plate 205 is provided on the outer side of the movable plate 201. A locking bolt 12 that is threadedly connected to any positioning hole 103 is installed in the middle of the first connecting plate 205.

[0030] The sliding block 204, in conjunction with the slide rail 102, allows the entire clamping structure 2 to move flexibly along the worktable 1 to accommodate boiler accessories of different sizes; the locking bolt 12, in conjunction with the positioning holes 103 at different positions, can securely lock the moving plate 201 in the desired position.

[0031] Specifically, when it is necessary to clamp boiler accessories, firstly, according to the size and shape of the accessories, push the moving plate 201 by hand so that the moving plate 201 slides on the slide rail 102 of the workbench 1 through the slider 204 at its lower end, thereby adjusting the two sets of clamping structures 2 to a suitable distance. Then, screw the locking bolt 12 into the nearest positioning hole 103 to fix the position of the moving plate 201. Subsequently, place the boiler accessories on the screening plate 5 and position them between the two clamping blocks 203. Start the electric push rod 202. The output end of the electric push rod 202 extends and pushes the clamping blocks 203 toward the boiler accessories until the two clamping blocks 203 are in close contact and press the accessories together, thus completing the clamping.

[0032] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, this embodiment discloses an implementation method for vibration chip removal:

[0033] The middle part of the guide plate 4 is inclined downward to form two inclined surfaces, and a chip discharge port 401 is opened in the middle part. The chip discharge port 401 is located at the bottom of the two inclined surfaces.

[0034] The vibration assembly includes a connecting shaft 701 rotatably connected inside the mounting groove. Multiple cams 702 that contact the inclined surface of the guide plate 4 are fixedly mounted on the outside of the connecting shaft 701. One end of the connecting shaft 701 passes through the workbench 1 and is equipped with a first synchronous pulley 703. The first synchronous pulleys 703 in the two sets of vibration assemblies are connected by a synchronous belt. One end of one of the connecting shafts 701 is also equipped with a second synchronous pulley 9. A motor 10 is provided on the outside of the workbench 1. A third synchronous pulley 11 is installed at the output end of the motor 10. The third synchronous pulley 11 and the second synchronous pulley 9 are connected by a synchronous belt.

[0035] Among them, the two sets of vibration components can work synchronously by being driven by the motor 10, ensuring that the force on both sides of the guide plate 4 is uniform and generating stable vibration. The inclined surface design of the guide plate 4 allows the debris falling on it to automatically slide towards the chip discharge port 401 in the middle under the action of gravity and vibration.

[0036] The upper end of the workbench 1 is provided with a limiting frame 104, and the screening plate 5 is located inside the limiting frame 104;

[0037] The limiting frame 104 prevents the screening plate 5 from moving horizontally or detaching during vibration, while allowing it to vibrate slightly up and down.

[0038] Specifically, when grinding or processing the clamped boiler parts, the motor 10 is started. The output shaft of the motor 10 drives the third synchronous pulley 11 to rotate. The third synchronous pulley 11 drives the second synchronous pulley 9 to rotate through the synchronous belt. The second synchronous pulley 9 drives the connecting shaft 701 connected to it to rotate. The connecting shaft 701 then transmits power to another set of first synchronous pulleys 703 through the first synchronous pulley 703 at its other end and the synchronous belt, driving the two connecting shafts 701 to rotate synchronously. Multiple cams 702 on each connecting shaft 701 rotate accordingly. During the rotation, the protruding part of the cam 702 periodically pushes up the inclined surface of the guide plate 4, causing it to generate high-frequency micro-vibration. This vibration is transmitted to the screening plate 5, causing it to vibrate as well. The processing debris falls onto the screening plate 5. The vibration of the screening plate 5 accelerates the debris from falling through its mesh and prevents the debris from accumulating and adhering on the plate surface. The debris falling onto the inclined surface of the guide plate 4 slides downward along the inclined surface under the action of continuous vibration and its own gravity, and finally all of them are collected and discharged through the chip discharge port 401.

[0039] like Figure 1 and Figure 3 As shown, this embodiment discloses an implementation method for cleaning the collection box 14:

[0040] A protective cover 13 is fixedly installed on one side of the workbench 1, and an installation port is opened on the other side. A collection box 14 located below the guide plate 4 is slidably connected inside the installation port, and a handle 15 is fixedly installed on the outside of the collection box 14.

[0041] A rectangular block 1401 is provided on the outer side of the collection box 14. A limit hole is provided at the upper end of the rectangular block 1401. A side plate 105 is provided on the outer side of the workbench 1. An installation hole is provided in the middle of the side plate 105. A connecting rod 16 is slidably connected inside the installation hole. A horizontal plate 17 is fixedly installed at the upper end of the connecting rod 16, and a second connecting plate 18 is fixedly installed at the lower end. A triangular block 19 that mates with the limit hole is provided at the lower end of the second connecting plate 18. A spring 20 is sleeved on the outer side of the connecting rod 16. The upper end of the spring 20 is fixedly connected to the lower end of the side plate 105, and the lower end is fixedly connected to the upper end of the second connecting plate 18.

[0042] Among them, by pulling the horizontal plate 17 upward, the triangular block 19 can be driven out of the limiting hole, thereby releasing the lock on the collection box 14 and allowing it to be pulled out for cleaning. The elastic force of the spring 20 maintains the triangular block 19 in the limiting hole under normal conditions, realizing automatic locking.

[0043] Specifically, when the debris in the collection box 14 is full and needs to be cleaned, the operator pulls the horizontal plate 17 upwards by hand. The horizontal plate 17 causes the connecting rod 16 to slide upwards in the mounting hole of the side plate 105. The connecting rod 16 pulls the second connecting plate 18 and the triangular block 19 at its lower end upwards together. During this process, the spring 20 sleeved on the outside of the connecting rod 16 is stretched. When the triangular block 19 is lifted until its lower end is completely disengaged from the limiting hole on the rectangular block 1401, the locking of the collection box 14 is released. The operator can then smoothly pull the collection box 14 out of the mounting opening of the workbench 1 using the handle 15 for emptying and cleaning. After cleaning, the collection box 14 is moved along the mounting... The rectangular block 1401 is pushed back into the workbench 1 until it contacts and abuts against the inclined surface of the triangular block 19. The collection box 14 is pushed inward. The rectangular block 1401 applies a downward component force through the inclined surface of the triangular block 19, which compresses the triangular block 19, the second connecting plate 18 and the connecting rod 16 to move slightly upward (slightly stretching the spring 20). When the collection box 14 is fully in place, the limiting hole on the rectangular block 1401 moves to just below the triangular block 19. At this time, the restoring force of the stretched spring 20 immediately pulls the second connecting plate 18 and the triangular block 19 downward to reset, so that the triangular block 19 is locked into the limiting hole, completing the automatic locking of the collection box 14.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
