Description

Technical Field

[0001] This utility model relates to the field of fastener testing, specifically to a clamp stress relief device. Background Technology

[0002] In automobile manufacturing, steel strip elastic clamps are key components widely used for fastening rubber hose joints in cooling and heating systems. These clamps not only need sufficient strength to ensure the safety and stability of the connection, but also need good elasticity and resilience to adapt to different working environment conditions. However, in actual production, the bending and forming process of steel strip elastic clamps must undergo stress relief treatment to ensure that they can accurately return to their design dimensions during use, thereby effectively completing the joint fastening task.

[0003] If stress relief is insufficient or substandard, the clamp may fail to return to its intended shape after opening, thus affecting its fastening performance. When clamps with substandard stress relief are used in automobile manufacturing, they may cause leakage problems at the interface, seriously affecting the normal operation of the vehicle and potentially posing safety hazards. Utility Model Content

[0004] The present invention aims to provide a clamp stress relief device to detect the stress relief status of clamps and prevent clamps with unqualified stress relief from being used, which would affect the normal operation of automobiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamp stress relief device, comprising a stress relief mechanism, the stress relief mechanism comprising an installation component and a compression unit, the installation component comprising a compression mounting plate, the compression unit comprising a guide rod and a driving component, two sliders that can move relative to each other are slidably disposed on the guide rod, the driving component is disposed on the compression mounting plate and can drive the sliders to slide closer or further away from the guide rod, and a compression track is fixed on the opposite side of the sliders for placing the clamp to be tested and for compressing the clamp to be tested.

[0006] The beneficial effects of this solution are as follows: By setting up a stress relief mechanism, a driving component drives a slider to slide on a guide rod, allowing the extrusion track on the opposite slider to extrude force on the clamp under test, simulating the stress condition of the clamp in actual use. This allows for the detection of whether the clamp's stress relief is qualified, preventing the use of clamps with unqualified stress relief, ensuring the normal operation of the vehicle, and reducing safety hazards caused by clamp problems. The stress relief mechanism consists of an installation component (extrusion mounting plate) and an extrusion unit (guide rod, driving component, slider, extrusion track). Its structural design is reasonable, the connection and cooperation between components are clear, and it is easy to manufacture and assemble. It has high operability in actual production and facilitates stress relief testing of clamps. The extrusion track effectively extrudes the clamp under test, and this extrusion method can realistically simulate the clamp's stress condition in the vehicle. The stress conditions during the tightening process of rubber hose joints in cooling and heating systems make the test results more reliable and authentic, accurately determining whether the clamps can accurately return to the design dimensions in actual use, ensuring their tightening performance. The drive component can drive the slider to slide closer to or away from the guide rod, meaning that the distance between the extrusion rails and the extrusion force on the clamps can be flexibly adjusted according to different specifications and requirements of clamps, thus adapting to stress release testing of various types of clamps and improving the versatility and practicality of the equipment. By performing stress release testing on clamps using this equipment, clamps that fail stress release tests can be screened out, preventing them from entering the automobile manufacturing process. This improves the quality of steel strip elastic clamps used in automobile manufacturing, ensures the safe and stable connection of rubber hose joints in automobile cooling and heating systems, and enhances the overall quality and reliability of automobiles.

[0007] Furthermore, the stress relief mechanism also includes a feeding unit, which includes a linear vibrator. A guide rail is fixed on the linear vibrator, and a clamp to be tested slides on the guide rail. Extrusion claws are fixed on opposite sides of the two sliders. Protrusions are provided on the close surfaces of the extrusion claws, forming an extrusion rail, which is connected to the guide rail.

[0008] Furthermore, the feeding unit also includes a limiting component, which includes a limiting member that is slidably disposed above the guide rail and can control the clamps on the guide rail to slide toward the extrusion rail.

[0009] Furthermore, the limiting component also includes a sensor, which is electrically connected to the limiting component.

[0010] Furthermore, the driving component includes a lead screw and an extrusion driving component. The lead screw is rotatably mounted on the extrusion mounting plate and threadedly connected to the slider. The extrusion driving component is fixedly mounted on the extrusion mounting plate and can drive the lead screw to rotate.

[0011] Furthermore, the stress relief mechanism also includes a frame and a discharge unit. The discharge unit includes an inclined rail, which is fixedly mounted on the frame and connected to the guide rail.

[0012] Furthermore, the discharge mechanism also includes a vibratory feeder, the inner wall of which is provided with a spiral surface that spirals upward from the bottom to the top of the vibratory feeder, and the top of the spiral surface is connected to the inclined rail.

[0013] Furthermore, it also includes a housing, which includes an outer shell, a base plate, and a support frame. The support frame is fixed to the base plate to form an equipment installation space. The installation space is provided with an inspection port and a feed port. An inspection door is hinged to the inspection port, and a feed door is hinged to the feed port.

[0014] Furthermore, the housing also includes a movable assembly, which comprises several movable parts rotatably disposed on the lower surface of the base plate.

[0015] Furthermore, it also includes a discharge chute, which includes a feed inlet fixed below the extrusion track.

[0016] Based on the above technical features, this solution provides the following technical benefits:

[0017] 1. The vibrator in the feeding unit drives the guide rail to vibrate, causing the clamps to be tested to slide on the guide rail, achieving automatic feeding, reducing manual operation, improving testing efficiency, and reducing labor intensity. The protrusions on the extrusion claws form an extrusion track and are connected to the guide rail, allowing the clamps to smoothly enter the extrusion track from the guide rail for testing, ensuring the continuity and smoothness of the feeding process.

[0018] 2. The limiting component in the limiting assembly is slidably positioned above the guide rail, precisely controlling the sliding of the clamps on the guide rail towards the extrusion rail. This prevents the clamps from entering the extrusion rail unprepared, ensuring the accuracy and orderliness of the detection. The sensor is electrically connected to the limiting component, enabling real-time monitoring of the clamp's position and status. Based on the detection results, the sensor controls the movement of the limiting component, further improving the accuracy and automation of the feeding control.

[0019] 3. The driving component adopts a combination of a lead screw and an extrusion drive. The lead screw is rotatably mounted on the extrusion mounting plate and threadedly connected to the slider. The extrusion drive drives the lead screw to rotate, thereby causing the slider to slide on the guide rod. This driving method can provide stable and precise driving force, ensuring the movement accuracy and stability of the slider, thereby improving the accuracy and reliability of clamp stress relief detection.

[0020] 4. Several moving parts in the moving assembly are rotatably mounted on the lower surface of the base plate, making the equipment easy to move and convenient to transfer and arrange between different work sites, thus improving the flexibility and applicability of the equipment.

[0021] 5. The feed inlet of the discharge chute is fixed below the extrusion track, which can accurately collect the clamps after testing, prevent the clamps from falling or being lost during the discharge process, ensure the integrity and orderliness of the discharge, and facilitate the subsequent classification and processing of the clamps after testing.

[0032] Example 1

[0033] Example 1 is basically as shown in the appendix. Figure 1-7 As shown, Figure 1-7 The clamp stress relief device shown includes a housing and a stress relief mechanism, such as... Figure 1 , Figure 2As shown, the housing includes an outer shell, a discharge chute 22, and a moving assembly. The outer shell is hinged with an inspection door 141 and a feed door 142. The outer shell includes a decorative panel 11, a support frame 12, and a base plate. The decorative panel 11 is riveted or welded to the support frame 12, and the support frame 12 is welded to the base plate. The moving assembly includes four casters, which are fixed to the lower surface of the base plate by bolts, thereby facilitating the movement of the equipment and changing the layout of the production site.

[0034] The stress relief mechanism includes a vibratory discharge unit and a feeding and extrusion unit. The vibratory discharge unit includes a vibratory plate 23 and an inclined rail. The vibratory plate 23 is used to hold the clamps to be tested, such as... Figure 3 As shown, the inner wall of the vibratory plate 23 is provided with a spiral surface, which spirals upward from the bottom to the top of the vibratory plate 23. The inclined rail is fixed on the shell, and the top of the inclined slope is connected to the top of the spiral surface. The bottom end is provided with a horizontal section. The inclined rail includes two tracks, which are parallel to each other and the distance between them is greater than the diameter of the clamp and less than the distance between the two pinch ears of the clamp.

[0035] The feeding and extrusion unit includes a mounting assembly, an extrusion unit, and a feeding unit. The mounting assembly includes an operation plate 21, a first mounting plate 211, and a cover plate 213. The operation plate 21 is connected to the housing by bolts. Figure 4 , Figure 5 As shown, the discharge chute 22 is fixed to the operating plate 21 by bolts, the first mounting plate 211 is fixed to the operating plate 21 by bolts, and two second mounting plates 212 are provided between the cover plate 213 and the operating plate 21. The second mounting plates 212 are fixedly connected to the operating plate 21 and the cover plate 213 by bolts.

[0036] like Figure 6 As shown, the extrusion unit includes a drive component, a guide rod 243, and two sliders 244. In this embodiment, the drive component is a lead screw 242 transmission assembly, which includes a lead screw 242 and a motor 241. The lead screw 242 is rotatably mounted on the second mounting plate 212. The guide rod 243 is fixed between the two second mounting plates 212 by bolts. The sliders 244 are slidably mounted on the guide rod 243 and threadedly connected to the lead screw 242. When the lead screw 242 rotates clockwise, the two sliders 244 move closer to each other. When the lead screw 242 rotates counterclockwise, the two sliders 244 move further apart. Extrusion claws 245 are fixed to the opposite sides of the sliders 244 by bolts. The extrusion claws 245 are provided with protrusions, which communicate with the guide plate 251 to form an extrusion track.

[0037] The feeding unit includes a linear vibrator 252, a pressing assembly, and a limiting assembly, such as... Figure 7As shown, the lower end of the linear vibrator 252 is fixed to the mounting plate by bolts, and the upper end is fixed with a guide plate 251. The guide plate 251 is connected to the horizontal section of the inclined rail. The pressing assembly includes a pressing mounting plate 261, a pressing telescopic component, and a pressing component. The pressing mounting plate 261 is fixed to the lower surface of the cover plate 213 by bolts. The pressing drive component is fixed to the pressing mounting plate 261 by bolts and is fixedly connected to the pressing component through a telescopic shaft.

[0038] When using it, first refer to Figure 8 Since the distance H between the two pinch ears of the clamp is greater than the diameter of the clamp, when the distance between the two guide rails of the inclined rail is greater than the diameter of the clamp but less than the distance between the two pinch ears, the two pinch ears of the clamp can overlap between the two guide rails of the inclined rail. Thus, the clamp to be tested is vibrated onto the inclined rail by the vibration of the vibrating plate 23, causing the clamp to slide along the inclined rail to the horizontal section and onto the guide plate 251 under the vibration of the straight vibrator 252. The output shaft of the pressing telescopic component 262 retracts, causing the clamp to slide along the guide plate 251 onto the extrusion track. Subsequently, the output shaft of the pressing telescopic component 262 extends... The screw 242 rotates to press the clamps on the guide plate 251, causing the clamps outside the extrusion track to stop sliding and restricting the movement of the clamps on the horizontal section of the inclined rail. Then, the screw 242 rotates to drive the sliders 244 to move closer to each other, thereby causing the protrusions forming the extrusion track to move closer to each other and complete the extrusion of the clamps. After extrusion, the screw 242 rotates in the opposite direction, causing the sliders 244 to move away from each other, thereby causing the protrusions forming the extrusion track to move away from each other, until the distance between the two protrusions is greater than the distance between the clamps, causing the clamps to disengage from the extrusion track and slide out of the discharge chute 22.

[0039] Example 2

[0040] Example 2 is basically the same as Example 1, except that the driving component of the extrusion unit includes a controller, two linear motors 241 and a wire sensor. The controller is electrically connected to the linear motors 241 and the wire sensor. The linear motors 241 are slidably mounted on the cover plate 213 and can drive the slider 244 to slide on the guide rod 243. One end of the wire sensor is fixedly connected to the slider 244 and the other end is fixedly connected to the second mounting plate 212. The wire sensor is electrically connected to the linear motors 241, so that the distance between the slider 244 and the second mounting plate 212 is detected by the wire sensor and transmitted to the controller. The controller controls the movement state of the slider 244 according to the information received from the wire sensor.
