Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing, in particular to a clamping and fixing device for door and window processing. Background Art

[0002] Doors and windows need to be positioned during production and processing to facilitate subsequent processing. However, existing doors and windows are mostly positioned manually during processing. This method is labor-intensive and can easily cause injuries to personnel during processing, reducing the safety of doors and windows during processing.

[0004] This patent uses a turntable to drive the movable plate and the connecting plate, thereby driving the clamping plate and clamping the workpiece. However, in order to maintain the stability of clamping, the turntable needs to be fixed through positioning holes and electric rods after clamping is completed. This will result in the turntable being rotated more or less in order to allow the electric rod to enter the positioning hole, causing the clamping plate to clamp the workpiece too much, causing the workpiece to be subjected to excessive pressure and cause damage. Utility Model Content

[0005] Based on this, it is necessary to provide a clamping and fixing device for door and window processing to address the problems of the existing technology. The bidirectional screw, slider, connecting rod and driving plate are used to drive the clamping plate to move toward and away from each other, thereby completing the clamping of the doors and windows. The clamping plate is driven to clamp by the rotation of the thread. The lateral force received by the clamping plate during clamping will not have much impact on the thread, thereby maintaining the stability of the clamping. The clamping can be stopped at any time through the turntable, and there is no need to worry about the clamping plate becoming loose or clamping too much to damage the doors and windows.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] See also Figure 1-4As shown, a clamping and fixing device for door and window processing includes a workbench 1 and a clamping plate 2, wherein the clamping plate 2 is mirror-imaged at both ends of the workbench 1, and the fixing device also includes a driving plate 21 and a driving mechanism 3, wherein the driving plate 21 is arranged in the cavity of the workbench 1 below the clamping plate 2, and a slide groove 11 is also arranged on the workbench 1, and the driving plate 21 can drive the clamping plate 2 to slide horizontally on the workbench 1 through the slide groove 11;

[0034] The driving mechanism 3 includes a connecting rod 31, a slider 32, a bidirectional screw 33 and a turntable 34. The bidirectional screw 33 is horizontally arranged between the driving plates 21 and both ends are rotatably arranged on both sides of the workbench 1. The slider 32 is mirror-arranged at both ends of the bidirectional screw 33 and a rotatable connecting rod 31 is arranged on the side of the slider 32 close to the driving plate 21. The end of the connecting rod 31 away from the slider 32 is rotatably mirror-arranged on the driving plate 21. The turntable 34 is arranged on one side of the workbench 1 and connected to one end of the bidirectional screw 33.

[0035] Specific work flow, when it is necessary to process the doors and windows, first the worker places the doors and windows to be processed on the workbench 1, and then drives the bidirectional screw 33 to rotate by rotating the turntable 34, thereby driving the slider 32 on the bidirectional screw 33 to move in opposite directions, and driven by the slider 32 and the connecting rod 31, the driving plate 21 drives the clamping plates 2 to move in opposite directions until the doors and windows are clamped between the clamping plates 2, and then stops rotating the turntable 34 to complete the clamping of the doors and windows;

[0036] When the door or window needs to be released, the turntable 34 is rotated to drive the slider 32 to move toward each other. Driven by the slider 32 and the connecting rod 31, the driving plate 21 drives the clamping plate 2 to move away from each other until the door or window is released.

[0037] The two-way screw 33, slider 32, connecting rod 31 and driving plate 21 are used to drive the clamping plate 2 to move toward and away from each other, thereby completing the clamping of doors and windows. The clamping plate 2 is driven by the rotation of the thread. The lateral force received by the clamping plate 2 during clamping does not have much influence on the thread, thereby maintaining the stability of the clamping. The clamping can be stopped at any time through the turntable 34, and there is no need to worry about the clamping plate 2 becoming loose or clamping too much to damage the doors and windows.

[0038] See also Figure 1 and Figure 2 As shown, a locking mechanism 4 is also provided between the turntable 34 and the workbench 1;

[0039] The locking mechanism 4 includes an electric push rod 41 and an abutment disc 42. The electric push rod 41 is arranged on the workbench 1. The abutment disc 42 is arranged at one end of the electric push rod 41 away from the workbench 1. A second anti-slip pad 421 is arranged on the side of the abutment disc 42 away from the electric push rod 41, and the second anti-slip pad 421 can abut against the turntable 34.

[0040] In the specific working process, when the clamping is completed, the electric push rod 41 is driven to push the contact disc 42 until the second anti-skid pad 421 on the contact disc 42 contacts the rotating disc 34. At this time, a large friction is generated between the second anti-skid pad 421 and the rotating disc 34, thereby preventing the bidirectional screw 33 from rotating.

[0041] By providing the electric push rod 41 and the abutment disc 42, it is ensured that during the clamping process, the friction force generated by the second anti-slip pad 421 on the abutment disc 42 and the turntable 34 prevents the turntable 34 from rotating, thereby preventing the rotation of the bidirectional screw 33 at any time, thereby increasing the stability of the clamping.

[0042] See also Figure 5 As shown, a plurality of rollers 12 whose rotation direction is consistent with the moving direction of the clamping plate 2 are evenly arranged on the workbench 1 , and the lower surface of the clamping plate 2 is higher than the highest point of the rollers 12 .

[0043] By arranging the roller 12 on the workbench 1, when the door and window are placed on the workbench 1 for clamping, the clamping plate 2 will push the door and window to move. At this time, the roller 12 will cause the door and window to move more smoothly, and the door and window will not be scratched by the fine debris on the workbench 1, thereby ensuring the work quality.

[0044] See also Figure 3 As shown, two limiting grooves 13 are respectively arranged on both sides of the workbench 1 , and both ends of the driving plate 21 are slidably arranged in the limiting grooves 13 .

[0045] The limiting groove 13 ensures that the driving plate 21 will maintain linear motion during movement, and the limiting groove 13 also supports the driving plate 21 , thereby ensuring that the clamping plate 2 will not sag and collide with the roller 12 .

[0046] See also Figure 5 As shown, the turntable 34 is also provided with a handle 341 for easy manual rotation.

[0047] By providing the handle 341, the worker can more easily rotate the turntable 34, and can know exactly how many turns he has made through the handle 341, thereby ensuring that there will be no excessive clamping during clamping, thereby reducing damage to doors and windows.

[0048] See also Figure 3As shown, a first anti-skid pad 22 is disposed at the opposite end of the clamping plate 2, and the first anti-skid pad 22 is made of a flexible material.

[0049] By using the first anti-slip pad 22 made of flexible material, the stability of clamping is ensured and the damage to the workpiece during clamping is reduced.

[0050] The present application uses a bidirectional screw 33, a slider 32, a connecting rod 31 and a driving plate 21 to drive the clamping plate 2 to move toward and away from each other, thereby completing the clamping of doors and windows. The clamping plate 2 is driven to clamp by the rotation of the thread. The lateral force received by the clamping plate 2 during clamping does not have much impact on the thread, thereby maintaining the stability of the clamping. The clamping can be stopped at any time through the turntable 34, and there is no need to worry about the clamping plate 2 becoming loose or clamping too much to damage the doors and windows.

[0051] By providing the electric push rod 41 and the abutment disc 42, it is ensured that during the clamping process, the friction force generated by the second anti-slip pad 421 on the abutment disc 42 and the turntable 34 prevents the turntable 34 from rotating, thereby preventing the rotation of the bidirectional screw 33 at any time, thereby increasing the stability of the clamping.

[0052] The above embodiments only express one or several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
