[0002] Aluminum profiles are an alloy material with aluminum as the main component, made by extrusion, stretching and other processes. Aluminum profiles are widely used in building doors, windows, curtain walls, aerospace, transportation (such as special radiator aluminum profiles for CPU radiators), furniture, solar energy, display equipment, medical equipment, automated machinery and other fields. In addition, aluminum profiles are also used in assembly line conveyor belts, elevators, dispensing machines, testing equipment, etc.

[0003] Aluminum profiles require different types of inspections depending on the field in which they are used. For example, aluminum profiles used in doors, windows, curtain walls and other fields, in addition to traditional appearance and size inspections: check whether the surface of the aluminum profile is flat and smooth, without cracks, scratches, dents or deformation; measure whether the size meets the design requirements, and also need to inspect its material and performance: inspect the mechanical properties of the aluminum profile, among which the impact resistance of the aluminum profile is one of the important inspection items, because in Guangxi, Hunan, Jiangxi and other regions of my country, every spring, they will encounter strong winds and hail, and the surface of aluminum profiles for doors and windows will often be hit by hail and strong winds blowing up branches. In order to ensure the subsequent normal and stable use, it is necessary to conduct impact resistance inspection on aluminum profiles for doors and windows in this area.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model provides a technical solution: a novel aluminum profile detection device, comprising a door and window aluminum profile 1, a detection unit is arranged above the door and window aluminum profile 1, and the detection unit comprises: a vertical tube 2, located above the door and window aluminum profile 1; a pull rod 3, vertically located inside the vertical tube 2; a pull ring 4, concentrically fixed to the top of the pull rod 3; a gasket 5, concentrically fixed to the bottom of the pull rod 3; a compression spring 6, sleeved on the outside of the pull rod 3, and the upper and lower ends of the compression spring 6 are respectively fixedly connected to the vertical tube 2 and the gasket 5; an impact The ball 7 is concentrically fixed to the bottom end of the gasket 5, and the bottom end of the impact ball 7 is in contact with the door and window aluminum profile 1; the pointer 8 is fixed to the outer wall of the gasket 5; the through groove 9 is vertically opened on the outer wall of the vertical tube 2, and the end of the pointer 8 away from the gasket 5 extends out of the through groove 9; the scale 10 is vertically arranged on the outer wall of the vertical tube 2; the ring 11 is fixedly sleeved on the bottom end of the outer wall of the vertical tube 2; a plurality of first balls 12 are provided, which are arranged in an annular shape on the lower surface of the ring 11, and the first balls 12 are in contact with the door and window aluminum profile 1.

[0025] In the specific implementation process, it is worth pointing out that the pull rod 3 can pass through the top of the vertical tube 2, and the outer wall of the pull rod 3 and the inner wall of the through hole at the top of the vertical tube 2 have a clearance fit. The clearance fit refers to a fit with a gap including a minimum gap equal to zero. By applying force to the pull ring 4 to pull upward, the pull rod 3 and the gasket 5 can move upward together. The elastic coefficient of the compression spring 6 is 5-50N / CM, and the impact ball 7 is made of stainless steel and has excellent strength. During the compression deformation of the compression spring 6 when the pull ring 4 is pulled upward, the value at the scale 10 pointed by the pointer 8 will change. By observing the value at the scale 10 pointed by the pointer 8, the compression strength of the compression spring 6 can be more intuitively known. The first ball 12 and the second ball 23 are both composed of a base and a steel ball. The base is fixedly connected to their contact surfaces, and the steel ball can roll but cannot be separated from the base.

[0026] Furthermore, an auxiliary unit is provided on one side of the outer wall of the vertical tube 2, and the auxiliary unit includes: a cross bar 13, which is laterally fixed to one side of the outer wall of the vertical tube 2; a ring 14, which is fixed to one end of the cross bar 13; a handle 15, which is sleeved on the outer wall of the cross bar 13; two bolts 16 are provided, which are respectively threadedly connected to the front and rear sides of the handle 15, and the bolts 16 pass through a part of the handle 15 and are tightly against the cross bar 13; a knob 17, which is located at the bottom end of the handle 15; a screw rod 18, which is concentrically fixed to the knob 17 The top of the handle 15 is provided with a screw rod 18, and the screw rod 18 is rotatably connected to the handle 15 through a ball bearing; a threaded barrel 19 is threadedly connected to the outer wall of the screw rod 18; a protrusion 20 is fixedly connected to the outer wall of the threaded barrel 19; a vertical groove 21 is vertically opened below the outer wall of the handle 15; the protrusion 20 is slidably assembled inside the vertical groove 21; a clamping plate 22 is fixedly connected to the end of the protrusion 20 away from the threaded barrel 19; a second ball 23 is provided in plurality and evenly distributed on the top of the clamping plate 22, and the second ball 23 is against the door and window aluminum profile 1.

[0027] In the specific implementation process, it is worth pointing out that the outer wall of the cross bar 13 and the inner wall of the through hole of the handle 15 are gap-matched. After the bolt 16 is rotated counterclockwise to separate from the cross bar 13, the cross bar 13 and the vertical tube 2 can be adjusted laterally, and the strength of the vertical tube 2 in the front-to-back direction can be adjusted. The second ball 23 and the first ball 12 can roll, and the position of the vertical tube 2 in the front-to-back direction can be adjusted, which is convenient for determining the impact position of the impact ball 7. The force applied to the knob 17 can rotate the screw rod 18, and the threaded tube 19, the protrusion 20, the splint 22 and the second ball 23 can move upward or downward. After the second ball 23 is tightly fitted against the lower surface of the door and window aluminum profile 1, the vertical stability of the vertical tube 2 during pulling the pull ring 4 can be enhanced.

[0028] Furthermore, a plurality of balls 24 are slidably engaged on both the front and rear sides of the protrusion 20 , and the balls 24 fit in with the inner wall of the vertical groove 21 .

[0029] In the specific implementation process, it is worth pointing out that the ball 24 can roll but cannot be separated from the protrusion 20 , which can reduce the friction force when the protrusion 20 slides up and down inside the vertical groove 21 .

[0030] Furthermore, anti-slip strips 25 are transversely embedded and fixedly connected to the front and rear sides of the outer wall of the cross bar 13 , and the anti-slip strips 25 are tightly pressed against the bolts 16 .

[0031] In the specific implementation process, it is worth pointing out that the outer wall of the cross bar 13 is fixedly connected with an anti-slip strip 25 , and the anti-slip strip 25 is tightly pressed against the bolt 16 .

[0032] Furthermore, convex strips 26 are fixedly connected to both the upper and lower sides of the cross bar 13 , and the convex strips 26 are slidably limitedly connected to the handle 15 through a sliding groove 27 .

[0033] In the specific implementation process, it is worth pointing out that the protruding strip 26 can slide transversely inside the sliding groove 27, but cannot move in the front-back and top-bottom directions, so as to facilitate the stable transverse sliding operation of the cross bar 13.

[0034] Working principle:

[0035] Impact resistance testing of aluminum profiles for doors and windows:

[0036] The tester holds the vertical tube 2 and fits the bottom end of the impact ball 7 with the surface of the door and window aluminum profile 1 to be tested for impact resistance. The vertical tube 2 is kept stable and the pull ring 4 is pulled upward. The impact ball 7 is away from the door and window aluminum profile 1, and the compression spring 6 is compressed and deformed to generate deformation potential energy. Then the force on the pull ring 4 is released. At this time, the deformation potential energy of the compression spring 6 is released instantly, so that the impact ball 7 can quickly hit the surface of the door and window aluminum profile 1. Then the vertical tube 2 is removed to see if there is a dent at the impact point, and the impact resistance test of the door and window aluminum profile 1 surface can be completed.

[0037] Impact force intensity control operation:

[0038] Based on the above process, the inspector can intuitively know the size of the impact force on the surface of the door and window aluminum profile 1 by observing the value at the scale 10 pointed by the pointer 8, and can control the intensity of the impact force of the impact ball 7 by the upward pulling distance of the pull ring 4, and can arbitrarily place the position of the vertical tube 2 to determine the impact position of the impact ball 7, so as to facilitate accurate impact resistance testing of the door and window aluminum profiles.

[0039] Clamping and stabilizing operations for the test tube:

[0040] After determining the positions of the vertical tube 2 and the impact ball 7, the inspector can apply force to the knob 17 to rotate the screw rod 18. The screw rod 18 in the rotating state can thread the threaded tube 19, and cooperate with the sliding limit of the protrusion 20 by the vertical groove 21 to make the threaded tube 19, the protrusion 20 and the clamping plate 22 move upward. After the second ball 23 is tightly fitted against the lower surface of the door and window aluminum profile 1, the force applied to the knob 17 is stopped. At this time, there is no need for the inspector to hold the vertical tube 2 to determine its stability, which can reduce the physical energy consumption of the inspector during operation.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
