Description

Technical Field

[0001] This utility model relates to the field of door and window testing technology, and in particular to a finished product testing machine for door and window production. Background Technology

[0002] Doors and windows are classified as enclosure components or partition components according to their location, and have different design requirements, such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing. New requirements include energy conservation. In cold regions, heat loss through gaps in doors and windows and the airtightness of doors and windows are important aspects of energy-saving design. Doors and windows are important components of the building envelope system, and they are also important components of the building's shape. Therefore, their shape, size, proportion, arrangement, color, and style have a great influence on the overall appearance of the building.

[0003] Chinese patent CN219810780U discloses a finished product testing machine for door and window production. By starting the output motor, the pulley, V-belt and driven wheel are driven to rotate, thereby moving the threaded rod and the sliding plates at both ends, and moving the limiting parts for adjustment. The hydraulic rod drives the extrusion plate to move downward, and moves the sliding parts, so that pressure tests can be performed on various positions of the door and window.

[0004] In the aforementioned patent literature, pressure is applied to the door and window by an extrusion plate to test the pressure resistance of the door frame. However, when the extrusion plate is used to test other parts of the door frame, it is necessary to separate the extrusion plate from the door and window, and then move the extrusion plate to other positions by moving the sliding parts to test the pressure resistance of other positions. During the testing process, it is necessary to continuously control the raising and lowering of the extrusion plate. The operation steps are cumbersome and cannot effectively conduct continuous testing, resulting in low testing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the existing technology: While the pressure resistance of door frames is tested by applying pressure to them using an extrusion plate, when testing other parts of the door frame, the extrusion plate needs to be separated from the door / window and moved to another location using a sliding component to test the pressure resistance of that location. During the testing process, the lifting and lowering of the extrusion plate needs to be constantly controlled, making the operation cumbersome and hindering effective continuous testing, resulting in low testing efficiency. Therefore, this invention proposes a finished product testing machine for door and window production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A finished product testing machine for door and window production includes a workbench, on which a clamping component for clamping door and window frames is installed. Sliding grooves are provided on both the front and rear sides of the workbench. A sliding member is provided on the top of the workbench, with its two ends slidably installed in the two sliding grooves respectively. A driving component for driving the sliding member to move horizontally back and forth is provided on the workbench.

[0008] An electrically controlled cylinder is fixedly mounted on the sliding member. An installation plate is fixedly mounted on the output end of the electrically controlled cylinder. Multiple pressure sensors are mounted on the lower surface of the installation plate. A rectangular plate is mounted on the input end of the multiple pressure sensors. A pressure roller is rotatably mounted on the lower surface of the rectangular plate.

[0009] Preferably, the sliding member has symmetrically provided limit holes, and a limit rod is vertically slidably installed in each of the two limit holes. Both limit rods are vertically fixedly installed on the rectangular plate.

[0010] Preferably, the drive assembly includes a reciprocating lead screw horizontally rotatably mounted on the lower surface of the worktable, a drive motor fixedly mounted on the lower surface of the worktable, a moving block threaded onto the reciprocating lead screw, and two connecting rods symmetrically fixedly mounted on the moving block. One end of each of the two connecting rods is fixedly connected to both ends of a sliding member, and one end of the output shaft of the drive motor is fixedly connected to one end of the reciprocating lead screw.

[0011] Preferably, a U-shaped protective cover is provided above the workbench, and both ends of the mounting plate are connected to the protective cover through connecting components.

[0012] Preferably, the connecting assembly includes a U-shaped frame, two slide rails, two telescopic springs, and two sliders. The U-shaped frame is fixedly installed at one end of the mounting plate. The two slide rails are symmetrically and vertically fixedly installed on the U-shaped frame. The two sliders are slidably sleeved on the two slide rails respectively. The two telescopic springs are respectively sleeved on the two slide rails. The two ends of the telescopic springs are fixedly connected to the U-shaped frame and the sliders respectively. The protective cover has strip-shaped holes on both the front and rear sides, and the sliders are slidably installed in the strip-shaped holes.

[0013] Preferably, a vertical rod is fixedly installed on the workbench, and a limiting block is vertically slidably sleeved on the vertical rod, with the limiting block fixedly installed on the side of the protective cover.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When inspecting door and window frames, the pressure roller is driven by an electric cylinder to contact and squeeze the door and window frame. Then, the sliding parts are driven by the drive assembly to move horizontally, which in turn drives the pressure roller to move horizontally on the door and window frame. This allows for continuous inspection of other parts of the door and window frame without repeatedly moving the pressure roller up and down. The operation is simple and effectively improves the inspection efficiency.

[0016] 2. When the pressure roller comes into contact with the door and window frame, the protective cover is placed on the workbench. If the door and window frame suddenly breaks or shatters, the protective cover can prevent fragments from flying and avoid the risk of injury to the operator. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-2A finished product inspection machine for door and window production includes a worktable 1, on which a clamping assembly 2 for clamping door and window frames is installed. Sliding grooves are provided on both the front and rear sides of the worktable 1. A sliding member 3 is provided on the top of the worktable 1, with its two ends slidably installed in the two sliding grooves. A drive assembly for driving the sliding member 3 to move horizontally back and forth is provided on the worktable 1. The drive assembly includes a reciprocating screw 10 horizontally rotatably installed on the lower surface of the worktable 1, a drive motor 11 fixedly installed on the lower surface of the worktable 1, a moving block 12 threadedly sleeved on the reciprocating screw 10, and two connecting rods 13 symmetrically fixedly installed on the moving block 12. One end of the two connecting rods 13 is fixedly connected to the two ends of the sliding member 3, and one end of the output shaft of the drive motor 11 is fixedly connected to one end of the reciprocating screw 10. The moving block 12 is threadedly sleeved on the reciprocating screw 10, and the upper surface of the moving block 12 slides in contact with the lower surface of the worktable 1. Thus, when the reciprocating screw 10 rotates, the moving block 12 will not rotate under the restriction of the worktable 1.

[0024] When it is necessary to drive the sliding member 3 to move horizontally back and forth on the worktable 1, the drive motor 11 is started, which drives the reciprocating screw 10 to rotate. Under the action of the reciprocating screw 10, the moving block 12 can be driven to move back and forth on the lower surface of the worktable 1. When the moving block 12 moves, it will drive the sliding member 3 to move horizontally back and forth on the worktable 1 through the connecting rod 13. The clamping component 2 is used to clamp and fix the door and window frame to be inspected. The clamping component 2 is disclosed in Chinese Patent No. CN219810780U, entitled "A Finished Product Inspection Machine for Door and Window Production", and will not be described in detail here.

[0025] An electric control cylinder 4 is fixedly installed on the sliding part 3. An installation plate 5 is fixedly installed on the output end of the electric control cylinder 4. Multiple pressure sensors 6 are installed on the lower surface of the installation plate 5. A rectangular plate 7 is installed on the input end of the multiple pressure sensors 6. A pressure roller 8 is rotatably installed on the lower surface of the rectangular plate 7.

[0026] When performing pressure resistance testing on door and window frames, press the control switch of the electric cylinder 4 to start the electric cylinder 4. The output end of the electric cylinder 4 drives the mounting plate 5 to move vertically downward. When the mounting plate 5 moves downward, it will drive the pressure roller 8 and the rectangular plate 7 to move towards the door and window frame until the pressure roller 8 contacts the door and window frame. The pressure sensor 6 installed between the rectangular plate 7 and the mounting plate 5 can measure the pressure applied by the pressure roller 8 on the door and window frame. At the same time, during the measurement, the sliding part 3 is driven to move horizontally through the drive component, which drives the pressure roller 8 to roll on the door and window frame to perform pressure resistance testing on other parts of the door and window frame. Other parts of the door and window frame can be continuously tested without repeatedly moving the pressure roller 8 up and down. The operation steps are simple and effectively improve the testing efficiency.

[0027] The sliding member 3 has symmetrical limit holes. Limit rods 9 are vertically slidably installed in both limit holes. Both limit rods 9 are vertically fixed on the rectangular plate 7. When the electric cylinder 4 drives the mounting plate 5 to move up and down, it drives the limit rods 9 to move up and down in the limit holes. The limit rods 9 can restrict the rotation of the mounting plate 5 and ensure that the mounting plate 5 moves vertically up and down.

[0028] Reference Figures 3-4 A U-shaped protective cover 14 is provided above the workbench 1. Both ends of the mounting plate 5 are connected to the protective cover 14 through connecting components. The connecting components include a U-shaped frame 15, two slide rails 16, two telescopic springs 17, and two sliders 18. The U-shaped frame 15 is fixedly installed on one end of the mounting plate 5. The two slide rails 16 are symmetrically and vertically fixedly installed on the U-shaped frame 15. The two sliders 18 are slidably sleeved on the two slide rails 16 respectively. The two telescopic springs 17 are sleeved on the two slide rails 16 respectively. The two ends of the telescopic springs 17 are fixedly connected to the U-shaped frame 15 and the sliders 18 respectively. The protective cover 14 has strip holes on both the front and rear sides. The sliders 18 are slidably installed in the strip holes.

[0029] In the initial state, under the elastic force of the telescopic spring 17, the slider 18 contacts the lower end of the U-shaped frame 15. When the mounting plate 5 moves vertically downward, it will simultaneously drive the protective cover 14 to move vertically downward. Before the pressure roller 8 contacts the door and window frame, the lower end of the protective cover 14 contacts the upper surface of the workbench 1, covering the door and window frame inside the protective cover 14. As the pressure roller 8 continues to move towards the door and window frame, the slider 18 moves relative to the slide rail 16, the telescopic spring 17 is compressed, and when the sliding member 3 drives the mounting plate 5 to move horizontally, the mounting plate 5 will drive the slider 18 to move horizontally within the strip hole opened in the protective cover 14. When the door and window frame is tested for pressure resistance, if the door and window frame suddenly breaks or shatters, the protective cover 14 can prevent fragments from flying and avoid the risk of injury to the operator.

[0030] A vertical rod 19 is fixedly installed on the workbench 1. A limit block 20 is vertically slidably mounted on the vertical rod 19. The limit block 20 is fixedly installed on the side of the protective cover 14. When the mounting plate 5 drives the slider 18 to move horizontally in the strip hole, the vertical rod 19 and the limit block 20 can prevent the protective cover 14 from moving horizontally.

[0031] In this invention, when performing pressure resistance testing on door and window frames, pressing the control switch of the electric cylinder 4 activates the cylinder 4. The output of the electric cylinder 4 drives the mounting plate 5 to move vertically downward. As the mounting plate 5 moves downward, it drives the pressure roller 8 and the rectangular plate 7 towards the door and window frame until the pressure roller 8 contacts the door and window frame. The pressure sensor 6 installed between the rectangular plate 7 and the mounting plate 5 can measure the pressure applied by the pressure roller 8 to the door and window frame. Simultaneously, during the measurement, the sliding member 3 is driven to move horizontally through the drive assembly, causing the pressure roller 8 to roll on the door and window frame, allowing for pressure resistance testing of other parts of the door and window frame. This allows for continuous testing of other parts of the door and window frame without repeatedly moving the pressure roller 8 up and down. The operation is simple and effectively improves testing efficiency.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
