Description

Technical Field

[0001] This utility model belongs to the field of sunroof production technology, specifically a sunroof frame strength testing device. Background Technology

[0002] The skylight frame is a skeleton system made of aluminum alloy and treated with anti-corrosion. The skylight frame is an important component that supports and fixes the skylight. Its design and manufacturing quality directly affect the use and safety of the skylight. Therefore, high-quality aluminum alloy materials must be used and strict anti-corrosion treatment must be carried out to ensure that it has good durability and stability.

[0003] In the existing technology, the compressive strength of the sunroof frame is an important indicator of the sunroof frame. Therefore, it is usually necessary to test the compressive strength of the sunroof frame during the processing of the sunroof frame. In long-term use and observation, it has been found that the existing sunroof frame strength testing devices are usually unable to quickly fix sunroof frames of different sizes. The sunroof frame is prone to shaking during the testing process, which affects the testing quality.

[0004] Therefore, this utility model provides a skylight frame strength testing device. Utility Model Content

This step, by providing a testing box, electric push rods, and pressing plate, allows for the pressing of the sunroof frame. The strength testing device, equipped with a support base, fixing plate, spring, and telescopic support shaft, presses and fixes the sunroof frame during the strength test using the testing box, electric push rod, and extrusion plate. This reduces the likelihood of the sunroof frame shaking during testing, thus improving its stability. It can also press and fix sunroof frames of different thicknesses, expanding the device's applicability. The first rotating groove and ball bearings change the sliding contact between the sunroof frame and the bottom of the inner wall of the testing box to a rolling contact between the sunroof frame and the ball bearings, reducing friction and wear on the sunroof frame during testing. This also makes it easier for workers to place the sunroof frame into the testing box, improving their work efficiency.

[0007] Preferably, the end of the extrusion plate is rotatably connected to a guide plate via a hinge; the other end of the guide plate extends out of the detection box; by providing a guide plate, this step can guide the process when the worker places the sunroof frame between a pair of extrusion plates, thereby making it easier for the worker to place the sunroof frame between a pair of extrusion plates and further improving the worker's work efficiency.

[0010] Preferably, a second support shaft is fixedly connected to the upper part of the inner side wall of the testing box; a sliding groove is provided in the middle of the extrusion plate; the sliding groove is fitted outside the second support shaft; this step, by providing the second support shaft and the sliding groove, can limit and support the movement of the extrusion plate when it moves inside the testing box, thereby reducing the displacement of the extrusion plate during movement and improving the stability of the extrusion plate during movement.

[0011] Preferably, the end of the detection box is provided with a second rotating groove; the second rotating groove is a pair and symmetrically arranged on the side near the guide plate; a third support shaft is fixedly connected to the middle of the second rotating groove; a roller is rotatably connected to the middle of the third support shaft; this step, by providing the second rotating groove, the third support shaft and the roller, can change the sliding contact between the guide plate and the detection box into a fixed contact, thereby reducing the friction when the guide plate contacts the detection box, thereby reducing the wear when the guide plate contacts the detection box, and improving the service life of the device.

It can also press and fix sunroof frames of different thicknesses, expanding the applicability of this device. By comprising a first rotating groove and a ball bearing, the sliding contact between the sunroof frame and the bottom of the inner wall of the testing box can be changed to the rolling contact between the sunroof frame and the ball bearing, thereby reducing the friction when the sunroof frame contacts the bottom of the inner wall of the testing box, thus reducing the wear caused to the sunroof frame during testing, and making it easier for workers to put the sunroof frame into the testing box, improving the work efficiency of workers.

[0014] 2.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a sunroof frame strength testing device includes a testing box 1; an electric push rod 11 is fixedly connected to the inner wall of the testing box 1; the electric push rod 11 is a pair and symmetrically arranged on the inner wall of the testing box 1; a pressing plate 12 is fixedly connected to the end of the electric push rod 11; a first rotating groove 13 is opened at the bottom of the inner wall of the testing box 1; there are multiple first rotating grooves 13 and they are evenly distributed at the bottom of the inner wall of the testing box 1; a ball bearing 14 is rotatably connected to the middle of the first rotating groove 13; the top of the side wall of the pressing plate 12 is fixedly connected to the pressing plate 12. A support base 15 is attached; a spring 17 is fixedly connected to the bottom of the support base 15; a fixing plate 16 is fixedly connected to the other end of the spring 17; a telescopic support shaft 18 connects the support base 15 and the fixing plate 16; the spring 17 is sleeved on the telescopic support shaft 18; during operation, the operator guides the sunroof frame to be inspected into the inspection box 1 from the end of the inspection box 1. At this time, the spring 17 will push the fixing plate 16 downward, thereby making the fixing plate 16 fit against the top of the sunroof frame. The operator then starts the inspection box 1 to inspect the pressing plate 12. The sunroof frame is pushed and then compressed to test its strength. This step, using a testing box 1, an electric push rod 11, and a compression plate 12, compresses the sunroof frame for strength testing. A support base 15, a fixing plate 16, a spring 17, and a telescopic support shaft 18 press and fix the sunroof frame during the strength test using the testing box 1, electric push rod 11, and compression plate 12, reducing the likelihood of the sunroof frame shaking during testing and thus improving its stability during the test. The device offers stability and can press and fix sunroof frames of different thicknesses, expanding its applicability. By providing a first rotating groove 13 and a ball bearing 14, the sliding contact between the sunroof frame and the bottom of the inner wall of the testing box 1 can be changed to a rolling contact between the sunroof frame and the ball bearing 14, thereby reducing the friction when the sunroof frame contacts the bottom of the inner wall of the testing box 1. This reduces wear on the sunroof frame during testing and makes it easier for staff to place the sunroof frame into the testing box 1, improving their work efficiency.

[0026] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the end of the extrusion plate 12 is rotatably connected to the guide plate 2 via a hinge; the other end of the guide plate 2 extends out of the detection box 1; by providing the guide plate 2, this step can guide the process when the staff puts the sunroof frame between a pair of extrusion plates 12, thereby making it easier for the staff to place the sunroof frame between a pair of extrusion plates 12 and further improving the staff's work efficiency.

[0027] Furthermore, such as Figures 1 to 3As shown, a first support shaft 3 is fixedly connected to the side wall of the testing box 1; the first support shaft 3 is a pair and symmetrically arranged on both sides of the testing box 1; a take-up reel 31 is rotatably connected to the middle of the first support shaft 3; a spiral spring is provided between the take-up reel 31 and the first support shaft 3; a connecting rope 32 is fixedly connected to the middle of the take-up reel 31; the other end of the connecting rope 32 is connected to the side wall of the guide plate 2; during operation, when the electric push rod 11 pushes the extrusion plate 12 to move, the extrusion plate 12 will drive the guide plate 2 to move, at which time the connecting rope 32 will pull the guide plate 2; when the testing is finished, the electric push rod 11 retracts. The extrusion plate 12 is reset, and the spiral spring drives the take-up wheel 31 to rotate, thereby winding up the connecting rope 32. At this time, the connecting rope 32 is always taut and pulls the guide plate 2. When the guide plate 2 contacts the detection box 1, the connecting rope 32 pulls the guide plate 2 away from the inside of the detection box 1 and slides along the edge of the detection box 1. This step, by providing the first support shaft 3, the take-up wheel 31 and the connecting rope 32, can reduce the situation where the guide plate 2 gets stuck inside the detection box 1 and loses its guiding effect when the electric push rod 11 retracts and drives the extrusion plate 12 to reset, thus improving the stability of the guide plate 2 during operation.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the top of the testing box 1 is provided with an observation window 4; the observation window 4 is made of transparent material; by providing the observation window 4, this step allows staff to conveniently observe the testing status of the skylight frame inside the testing box 1, thereby improving the work efficiency of the staff.

[0029] Furthermore, such as Figure 2 and Figure 5 As shown, a second support shaft 5 is fixedly connected to the upper part of the inner side wall of the testing box 1; a sliding groove 51 is provided in the middle of the extrusion plate 12; the sliding groove 51 is sleeved on the outside of the second support shaft 5; by providing the second support shaft 5 and the sliding groove 51, this step can limit and support the movement of the extrusion plate 12 when it moves inside the testing box 1, thereby reducing the displacement of the extrusion plate 12 when it moves and improving the stability of the extrusion plate 12 when it moves.

[0030] Furthermore, such as Figure 3 and Figure 4As shown, the end of the detection box 1 is provided with a second rotating groove 6; the second rotating groove 6 is a pair and symmetrically arranged on the side near the guide plate 2; a third support shaft 61 is fixedly connected to the middle of the second rotating groove 6; a roller 62 is rotatably connected to the middle of the third support shaft 61; by providing the second rotating groove 6, the third support shaft 61 and the roller 62, this step can change the sliding contact between the guide plate 2 and the detection box 1 into a fixed contact, thereby reducing the friction when the guide plate 2 and the detection box 1 are in contact, thereby reducing the wear when the guide plate 2 and the detection box 1 are in contact, and improving the service life of this device.

[0031] Working principle: During operation, the operator guides the sunroof frame to be tested into the testing box 1 from the end of the testing box 1. At this time, the spring 17 pushes the fixing plate 16 downward, so that the fixing plate 16 fits against the top of the sunroof frame. The operator then starts the testing box 1 to push the compression plate 12, thereby compressing the sunroof frame and testing its strength. When the electric push rod 11 pushes the compression plate 12 to move, the compression plate 12 will drive the guide plate 2 to move. At this time, the connecting rope 32 will pull the guide plate 2. When the test is finished, the electric push rod 11 retracts, driving the compression plate 12 to reset. At this time, the spiral spring will drive the take-up wheel 31 to rotate, thereby winding the connecting rope 32. At this time, the connecting rope 32 is always in a taut state, pulling the guide plate 2. When the guide plate 2 contacts the testing box 1, the connecting rope 32 will pull the guide plate 2 away from the inside of the testing box 1 and slide along the edge of the testing box 1.
