Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a self-positioning clamping device for processing warm edge strips. Background Technology

[0002] Warm edge strips are high-performance spacer materials used in insulated glass systems. They are typically made of polymer or composite materials and have low thermal conductivity. Their main function is to reduce heat conduction at the edges of the insulated glass, improve its insulation performance, and reduce heat exchange between the indoor and outdoor spaces, thereby achieving energy-saving and heat-insulating effects.

[0003] For example, a Chinese patent discloses a self-positioning clamping device (patent number: CN214264725U). This device uses guide pillars to ensure overall structural stability. A vertical cylinder operates, pushing the guide pillar fixing plate downwards. A stop cylinder operates, releasing the second tray, allowing it to slide on the connecting piece. A gripper cylinder operates, clamping the workpiece with a centering gripper. After clamping, a braking cylinder operates, fixing the position of the second tray. The vertical cylinder then operates, lifting the workpiece upwards. During the robot's feeding of the workpiece into the machine tool, the workpiece's posture remains unchanged, achieving controllable loading position. The final loading position of the workpiece is actually determined by its position before clamping, making positioning relatively easy. This device has a compact structure, adaptive positioning, low environmental requirements, is easy to debug, and facilitates standardization.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: As mentioned above, when the clamped object needs to move inside, the device clamps the object too tightly, which may cause the clamped object to be unable to move. The clamping is too tight and prevents it from moving, which will lead to deviation in processing accuracy and fail to achieve the expected processing effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a self-positioning clamping device for processing warm edge strips. It solves the technical problem that when the clamped object needs to move internally, the device clamps the object too tightly, which may prevent the object from moving. This excessive clamping can lead to deviations in processing accuracy and prevent the desired processing effect from being achieved.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-positioning clamping device for processing warm edge strips includes a base with an air cavity inside. A clamping mechanism for fixing the warm edge strip is slidably installed inside the air cavity. The clamping mechanism includes a pneumatic plate slidably installed inside the air cavity. An L-shaped connecting plate is fixedly installed on the side wall of the pneumatic plate. A fixing rod is fixedly installed on the side wall of the L-shaped connecting plate. A first spring is sleeved on the side wall of the fixing rod. A connecting seat is fixedly installed at the end of the fixing rod away from the L-shaped connecting plate. A fixing plate is fixedly installed on the top of the connecting seat. A roller is rotatably installed inside the fixing plate.

[0008] Preferably, a connecting rod is slidably installed inside the base, and a lifting plate is fixedly installed on the top of the connecting rod.

[0009] Preferably, a second spring is sleeved on the side wall of the lifting plate, and the second spring is fixedly installed with the lifting plate.

[0010] Preferably, the second spring is fixedly installed with the base, and a fixing strip is fixedly installed at the bottom of the connecting rod.

[0011] Preferably, a limiting shaft is rotatably installed inside the fixing bar, and a compressor is fixedly installed inside the base.

[0012] Preferably, an air pipe is fixedly installed at the output end of the compressor, and the air pipe is located inside the air chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The gas inside the air chamber will be released from the air chamber through the compressor. At this time, the first spring will rebound under force. The first spring will drive the fixed rod to move from both sides to the middle. The fixed rod will drive the L-shaped connecting plate to move from both sides to the middle. The L-shaped connecting plate will drive the pneumatic plate to move from both sides to the middle. At this time, the fixed rod will also drive the connecting seat to move from both sides to the middle. The connecting seat will drive the fixed plate to move from both sides to the middle. The fixed plate will drive the roller to move from the middle to both sides, so that the roller clamps the warm edge strip. The warm edge strip can slide on the side wall of the roller, thereby achieving the function of clamping and facilitating the processing of the warm edge strip.

[0015] 2. Place the warm edge strip above the base, pull the lifting plate, the lifting plate drives the connecting rod to move from bottom to top, causing the second spring to be compressed. The connecting rod drives the fixing strip to move from bottom to top, and the fixing strip drives the limiting shaft to move from bottom to top. At this time, place the warm edge strip at its bottom, release the lifting plate, the second spring is forced to rebound and place the limiting shaft above the warm edge strip, thereby preventing the warm edge strip from flying out of the base during processing.

[0022] This application provides a self-positioning clamping device for processing warm edge strips. It effectively solves the problem that when the clamped object needs to move internally, the device may clamp it too tightly, potentially preventing movement and leading to machining accuracy deviations and failure to achieve the desired processing effect. The gas inside the air chamber is released from the air chamber by the compressor. At this time, the first spring rebounds, causing the fixing rod to move from both sides towards the center. The fixing rod then moves the L-shaped connecting plate from both sides towards the center, which in turn moves the pneumatic plate from both sides towards the center. Simultaneously, the fixing rod also moves the connecting seat from both sides towards the center. The movement involves the connecting seat moving the fixing plate from both sides towards the center, and the fixing plate moving the rollers from the center towards both sides, causing the rollers to clamp the warm edge strip. The warm edge strip can slide on the side wall of the rollers, thus achieving the function of clamping and facilitating the processing of the warm edge strip. The warm edge strip is placed above the base, and the lifting plate is pulled. The lifting plate moves the connecting rod from bottom to top, causing the second spring to be compressed. The connecting rod moves the fixing strip from bottom to top, and the fixing strip moves the limiting shaft from bottom to top. At this time, the warm edge strip is placed at its bottom. The lifting plate is released, and the second spring rebounds, placing the limiting shaft above the warm edge strip, thus preventing the warm edge strip from flying out of the base during processing. Example

[0023] like Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that when the clamped object needs to move internally, the device clamps the object too tightly, which may prevent the object from moving. Excessive clamping prevents movement, leading to deviations in processing accuracy and failing to achieve the expected processing effect. The overall concept is as follows: A self-positioning clamping device for processing warm edge strips includes a base 11, with an air cavity 12 inside the base 11. A clamping mechanism for fixing the warm edge strip is slidably installed inside the air cavity 12. The clamping mechanism includes a pneumatic plate 13, which is slidably installed inside the air cavity 12. An L-shaped connecting plate 14 is fixedly installed on the side wall of the pneumatic plate 13, and a fixing rod 15 is fixedly installed on the side wall of the L-shaped connecting plate 14. A first spring 16 is sleeved on the side wall of the fixing rod 15. The fixing rod 15 is located away from the L-shaped connecting plate 14. A connecting seat 17 is fixedly installed at one end, and a fixing plate 18 is fixedly installed on the top of the connecting seat 17. A roller 19 is rotatably installed inside the fixing plate 18. The gas inside the air chamber 12 will be released from the air chamber 12 through the compressor 26. At this time, the first spring 16 is forced to rebound. The first spring 16 drives the fixing rod 15 to move from both sides to the middle. The fixing rod 15 drives the L-shaped connecting plate 14 to move from both sides to the middle. The L-shaped connecting plate 14 drives the pneumatic plate 13 to move from both sides to the middle. At this time, the fixing rod 15 will also drive the connecting seat 17 to move from both sides to the middle. The connecting seat 17 drives the fixing plate 18 to move from both sides to the middle. The fixing plate 18 drives the roller 19 to move from the middle to both sides, so that the roller 19 clamps the warm edge strip, and the warm edge strip can slide on the side wall of the roller 19, thereby achieving the function of clamping and facilitating the processing of the warm edge strip.

[0024] A connecting rod 21 is slidably installed inside the base 11. A lifting plate 22 is fixedly installed on the top of the connecting rod 21. A second spring 23 is sleeved on the side wall of the lifting plate 22. The second spring 23 is fixedly installed with the lifting plate 22 and the base 11. A fixing strip 24 is fixedly installed at the bottom of the connecting rod 21. A limit shaft 25 is rotatably installed inside the fixing strip 24. A compressor 26 is fixedly installed inside the base 11. When the warm edge strip is placed above the base 11, the lifting plate 22 is pulled. The lifting plate 22 drives the connecting rod 21 to move from bottom to top, causing the second spring 23 to be compressed. The connecting rod 21 drives the fixing strip 24 to move from bottom to top. The fixing strip 24 drives the limit shaft 25 to move from bottom to top. At this time, the warm edge strip is placed at its bottom. The lifting plate 22 is released. The second spring 23 rebounds and places the limit shaft 25 above the warm edge strip, thereby preventing the warm edge strip from flying out of the base 11 during processing.

[0025] A gas pipe 27 is fixedly installed at the output end of the compressor 26. The gas pipe 27 is located inside the gas chamber 12, which facilitates the transmission of gas into the gas chamber 12.

[0026] To address the problems existing in the prior art, this utility model provides a self-positioning fixture device for processing warm edge strips. Gas inside the air chamber 12 is released from the air chamber 12 via the compressor 26. At this time, the first spring 16 rebounds under force, driving the fixing rod 15 to move from both sides towards the center. The fixing rod 15 then drives the L-shaped connecting plate 14 to move from both sides towards the center. The L-shaped connecting plate 14 drives the pneumatic plate 13 to move from both sides towards the center. Simultaneously, the fixing rod 15 also drives the connecting seat 17 to move from both sides towards the center. The connecting seat 17 drives the fixing plate 18 to move from both sides towards the center. The fixing plate 18 then drives the roller 19 from the center towards both sides. The movement causes the roller 19 to clamp the warm edge strip, and the warm edge strip can slide on the side wall of the roller 19, thus achieving the function of clamping and facilitating the processing of the warm edge strip. The warm edge strip is placed above the base 11, and the lifting plate 22 is pulled. The lifting plate 22 drives the connecting rod 21 to move from bottom to top, causing the second spring 23 to be compressed. The connecting rod 21 drives the fixing bar 24 to move from bottom to top, and the fixing bar 24 drives the limiting shaft 25 to move from bottom to top. At this time, the warm edge strip is placed at its bottom. The lifting plate 22 is released, and the second spring 23 is forced to rebound, placing the limiting shaft 25 above the warm edge strip, thus preventing the warm edge strip from flying out of the base 11 during processing.

[0027] Base 11: Serves as the basic support structure for the entire clamping device, providing a platform for the installation and operation of other components;

[0028] Air chamber 12: Contains gas, providing a power source and movement space for the clamping mechanism;

[0029] Clamping mechanism:

[0032] Fixed rod 15: Under the action of the first spring, it drives the connecting seat and other components to move, thereby achieving clamping;

[0033] First spring 16: When gas is released, the spring rebounds and drives the fixing rod and other components to move from both sides to the middle to achieve the clamping function; when gas is filled, it is compressed to store energy.

[0034] Connecting seat 17: connects the fixing rod and the fixing plate, and transmits the clamping force;

[0035] Fixed plate 18: Fixes the roller and, with the movement of other components, drives the roller to clamp the warm edge strip;

[0036] Roller 19: Directly contacts and clamps the warm edge strip, while allowing the warm edge strip to slide during processing;

[0037] Connecting rod 21: connects the lifting plate and the fixing strip, and transmits the lifting action;

[0038] Lifting plate 22: It is manually pulled, which drives the connecting rod and other components to move;

[0039] Second spring 23: It is compressed when the lifting plate is pulled and rebounds when the lifting plate is released, driving the limit shaft to reset and preventing the warm edge strip from flying out;

[0040] Fixed bar 24: connects the connecting rod and the limiting shaft, transmitting motion;

[0041] Limiting shaft 25: Under the action of the second spring, it is located above the warm edge strip to prevent the warm edge strip from flying out of the base during processing;

[0042] Compressor 26: Controls the filling and releasing of gas in the air chamber to realize the opening and clamping actions of the clamping mechanism;

[0043] Air tube 27: Transmits the gas output from the compressor to the air chamber.

[0044] Working principle:

[0045] First, place the warm edge strip above the base 11, pull the lifting plate 22, the lifting plate 22 drives the connecting rod 21 to move from bottom to top, causing the second spring 23 to be compressed. The connecting rod 21 drives the fixing bar 24 to move from bottom to top, and the fixing bar 24 drives the limiting shaft 25 to move from bottom to top. At this time, place the warm edge strip at its bottom, release the lifting plate 22, the second spring 23 is forced to rebound and place the limiting shaft 25 above the warm edge strip, thereby preventing the warm edge strip from flying out of the base 11 during processing.

[0046] The second step is to start the compressor 26. The gas inside the air chamber 12 will be released from the air chamber 12 through the compressor 26. At this time, the first spring 16 is forced to rebound. The first spring 16 drives the fixed rod 15 to move from both sides to the middle. The fixed rod 15 drives the L-shaped connecting plate 14 to move from both sides to the middle. The L-shaped connecting plate 14 drives the pneumatic plate 13 to move from both sides to the middle. At this time, the fixed rod 15 will also drive the connecting seat 17 to move from both sides to the middle. The connecting seat 17 drives the fixed plate 18 to move from both sides to the middle. The fixed plate 18 drives the roller 19 to move from the middle to both sides, so that the roller 19 clamps the warm edge strip. The warm edge strip can slide on the side wall of the roller 19, thereby achieving the function of clamping and facilitating the processing of the warm edge strip.

However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
