Technical Field

[0001] This utility model relates to the field of strength testing technology, specifically to a strength testing device for processing automotive sealing strips. Background Technology

[0002] As a crucial component of the vehicle's sealing system, automotive weatherstripping directly impacts a vehicle's waterproofing, dustproofing, sound insulation, and sealing performance. During the manufacturing process, strength is a key indicator of quality, directly affecting the weatherstripping's lifespan and reliability.

[0003] In existing technologies, most common sealing strip strength testing devices on the market adopt simple tensioning structures, and the sealing strip is subjected to tensile testing manually. However, such devices often have the following problems: the clamping structure is not stable enough, it is easy to slip or loosen during the tensioning process, and it is easily affected by frictional resistance, which affects the accuracy of the test results. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing sealing strip strength testing devices tend to slip during the stretching process after the sealing strip is fixed, which affects the test results.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A strength testing device for automotive sealing strip processing includes a base with several support legs fixedly connected to the lower end of the base and a controller installed at the front end of the base. It also includes a tensioning mechanism and a fixing mechanism. The tensioning mechanism includes a motor and a movable seat. The motor is horizontally fixed to one end of the base and drives the movable seat to move horizontally on the base. A mounting seat is vertically fixed to the other end of the base. Two fixing mechanisms are symmetrically distributed and respectively installed on the mounting seat and the movable seat. The fixing mechanisms are used to clamp both ends of the sealing strip.

[0007] Furthermore, the output end of the motor is fixedly connected to a first screw, the upper end of the base is provided with a first sliding groove, the first screw is horizontally rotatably connected to the first sliding groove, and the lower end of the movable seat is fixedly connected to a first slider, the first slider is threadedly connected to the first screw and horizontally slides in the first sliding groove.

[0008] Furthermore, the upper end of the base is provided with limiting grooves symmetrically distributed on both sides of the first sliding groove, and the lower end of the movable seat is fixed with limiting blocks symmetrically distributed on both sides of the first slider, and the limiting blocks are horizontally slidably connected in the limiting grooves.

[0009] Furthermore, the fixing mechanism includes an adjusting rod and a clamp. A knob and a first bevel gear are fixedly connected to both ends of the adjusting rod, respectively. Second bevel gears are symmetrically distributed on both sides of the first bevel gear. A second screw is fixedly connected to the outer side of the second bevel gear. The two second screws have the same pitch and opposite directions of rotation. The two clamps are symmetrically distributed, and a second slider is fixedly connected to the rear end of each clamp. The second slider is threadedly connected to the two second screws.

[0010] Furthermore, both the mounting base and the movable base are provided with toothed grooves. The first bevel gear and the second bevel gears meshing on both sides are rotatably disposed in the toothed grooves. Both the mounting base and the movable base have second sliding grooves symmetrically distributed on both sides of the toothed grooves on one side. The second screw is horizontally rotatably connected to the second sliding groove, and the second slider is horizontally slidingly engaged in the second sliding groove.

[0011] Furthermore, the clamp is designed with an "F" shaped structure, and the end of the clamp is fixed with a fastening protrusion, and the fastening protrusions at the ends of the two clamps interlock and mesh with each other.

[0012] Furthermore, a support frame is provided between the two fixing mechanisms. The support frame is vertically fixed to the base, and a support groove is provided at the upper end of the support frame. A pressure detector is installed in the support groove.

[0023] like Figure 1-6 As shown, a strength testing device for automotive sealing strip processing includes a base 1, with several support legs 2 fixedly connected to the lower end of the base 1, and a controller 3 installed at the front end of the base 1. It also includes a tensioning mechanism 4 and a fixing mechanism 5. The tensioning mechanism 4 includes a motor 401 and a movable seat 403. The motor 401 is horizontally fixed to one end of the base 1, and drives the movable seat 403 to move horizontally on the base 1. A mounting base 101 is vertically fixed to the other end of the base 1. Two fixing mechanisms 5 are symmetrically distributed and respectively installed on the mounting base 101 and the movable seat 403. The fixing mechanisms 5 are used to clamp both ends of the sealing strip.

[0024] like Figure 2 , 4As shown in Figures 5 and 6, the fixing mechanism 5 includes an adjusting rod 501 and a clamp 506. A knob 502 and a first bevel gear 503 are fixedly connected to both ends of the adjusting rod 501. Symmetrically distributed second bevel gears 504 mesh with both sides of the first bevel gear 503. A second screw 505 is fixedly connected to the outer side of each second bevel gear 504. The two second screws 505 have the same pitch and opposite directions of rotation. Two clamps 506 are symmetrically distributed, and a second slider 507 is fixedly connected to the rear end of each clamp 506. The second slider 507 is threaded onto the two second screws 505. Both the mounting base 101 and the movable base 403 have toothed grooves. The first bevel gear 502... The second bevel gear 504 and its two sides are rotatably disposed in the tooth groove. The mounting base 101 and the movable base 403 are both provided with second sliding grooves symmetrically distributed on both sides of the tooth groove. The second screw 505 is horizontally rotatably connected in the second sliding groove. The second slider 507 is horizontally slidably engaged in the second sliding groove. The clamp 506 is designed with an "F" shape. The end of the clamp 506 is fixedly connected with a fastening protrusion 508. The fastening protrusions 508 at the ends of the two clamps 506 are interlocked and meshed. By rotating the knob 502, the symmetrical clamps 506 are driven to clamp and fix the end of the sealing strip. The clamping and fixing of the two ends of the sealing strip is achieved by using two fixing mechanisms 5.

[0025] like Figure 2-4 As shown, the output end of the motor 401 is fixedly connected to a first screw 402. The upper end of the base 1 is provided with a first sliding groove 102. The first screw 402 is horizontally rotatably connected to the first sliding groove 102. The lower end of the movable seat 403 is fixedly connected to a first slider 404. The first slider 404 is threadedly connected to the first screw 402 and horizontally slides within the first sliding groove 102. The upper end of the base 1 is provided with limiting grooves 103 symmetrically distributed on both sides of the first sliding groove 102. The lower end of the movable seat 403 is fixedly connected to limiting blocks 405 symmetrically distributed on both sides of the first slider 404. The limiting blocks 405 are horizontally slidably connected within the limiting grooves 103. Driven by the motor 401, the movable seat 403 moves horizontally on the base 1, thereby stretching the fixed sealing strip and thus detecting the sealing strip.

[0026] like Figure 1 , 2 As shown, a support frame 6 is provided between the two fixed mechanisms 5. The support frame 6 is vertically fixed to the base 1. The upper end of the support frame 6 is provided with a support groove 601. A pressure detector 602 is installed in the support groove 601. The stretched sealing strip presses down on the pressure detector 602 in the support groove 601. The pressure sensor in the pressure detector 602 detects and transmits the pressure value when the sealing strip is stretched, thereby realizing the strength detection of the sealing strip.

[0027] In use, after the sealing strip is placed in the support groove 601, the two ends of the sealing strip are clamped and fixed by the fixing mechanism 5 on the mounting base 101 and the movable base 403. Rotating the knob 502 drives the adjusting rod 501 to rotate, which in turn drives the first bevel gear 503 to rotate, which in turn drives the symmetrical second bevel gear 504 to rotate, which in turn drives the second screw 505 to rotate, which in turn drives the second slider 507 to slide in the second slide groove, which in turn drives the symmetrical clamps 506 to move towards each other, thereby clamping and fixing the ends of the sealing strip. Under the action of the controller 3, the output end of the motor 401 drives... The first screw 402 rotates, thereby driving the first slider 404 to slide within the first groove 102, which in turn drives the movable seat 403 to slide away from the mounting seat 101 on the base 1. The fixing mechanism 5 on the movable seat 403 causes the sealing strip it holds to stretch. The stretched sealing strip presses against the pressure detector 602 in the support groove 601. The pressure sensor in the pressure detector 602 detects the change in the pressure force exerted on the pressure detector 602 when the sealing strip is stretched and transmits it to the controller 3. The strength of the sealing strip is fed back by the change in the pressure force exerted on the pressure detector 602 when the sealing strip is stretched.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
