Description

Technical Field

[0001] This utility model relates to the field of clamping technology for bolt inspection, specifically a clamping device for bolt inspection. Background Technology

[0002] In modern industrial production, bolts are widely used fasteners, and their quality directly affects product performance and safety. Therefore, comprehensive and accurate testing of bolts is crucial, and the first step in the testing process is to ensure the bolts are securely clamped.

[0003] Traditional bolt clamping devices have several drawbacks. Firstly, their centering adjustment function is inadequate for bolts of different specifications. When faced with bolts of various sizes, it is difficult to quickly and accurately position them at the inspection center. This not only consumes a significant amount of time for manual adjustment but also easily leads to centering deviations, thus affecting the accuracy of the inspection results. In some machinery manufacturing enterprises, the inaccurate centering of traditional clamps results in large dimensional measurement errors and a high misjudgment rate when inspecting bolts. Secondly, traditional clamping devices lack the ability to adapt to the shape and surface condition of bolts. In actual production, bolts may have irregular shapes or dimensional deviations due to differences in manufacturing processes or wear and deformation after use. The rigid clamping method of traditional clamps cannot automatically adjust to these differences, easily leading to unstable clamping. During inspection, the bolt may wobble or shift, severely interfering with the inspection work. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for bolt inspection, which solves the technical problems of traditional bolt clamping devices that are difficult to center and clamp bolts of different specifications, cannot adapt to different bolt shapes and surface conditions, and are prone to damaging the bolt surface, affecting the use after inspection. It achieves the purpose of being able to quickly center bolts of various specifications, using an adaptive structure to stably clamp bolts of different shapes and surfaces, and avoiding damage to the bolt surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for bolt detection, comprising a support fixing plate, a centering clamping moving part, and an adaptive clamping part. Support fixing legs are symmetrically fixedly installed on the bottom outer wall of the support fixing plate, and support pads are fixedly installed on the bottom outer wall of the support fixing legs. The centering clamping moving part is disposed on the top outer wall of the support fixing plate. The adaptive clamping part is disposed on the top of the centering clamping moving part.

[0006] Preferably, the centering clamping moving part specifically includes: a guide fixing block, symmetrically fixedly installed on the top outer wall of the support fixing plate; a motor fixing bracket, fixedly installed on one side outer wall of the support fixing plate; and a rectangular fixing block, fixedly installed on the top outer wall of the support fixing plate.

[0007] Preferably, the top outer wall of each guide fixing block is provided with a sliding groove, and guide rods are fixedly connected between the inner walls of each sliding groove. A motor is fixedly installed inside the motor fixing frame. The top outer wall of each rectangular fixing block is provided with a rectangular sliding groove, and a positive threaded screw is fixedly connected to the output end of the motor.

[0008] A motor is installed, which is connected to a forward threaded screw via its output end. The forward threaded screw is connected to a reverse threaded screw, and both are threadedly connected to the threaded sleeve on the movable slider. When the motor rotates, it can drive the forward and reverse threaded screws to rotate synchronously, thereby driving the movable slider to move within the rectangular groove. At the same time, the movable slider cooperates with the guide slider to drive the movable platform one and movable platform two to move relative to or away from each other, realizing the centering and clamping function of bolts. It can adapt to the centering and clamping of bolts of different specifications, improving the versatility and applicability of the device.

[0009] Preferably, the other end of the positive threaded screw movably penetrates the outer wall of the rectangular fixed block and extends into the interior of the rectangular slide groove. The other end of the positive threaded screw is fixedly connected to a connecting rod, and the other end of the connecting rod is fixedly connected to a reverse threaded screw. The other end of the reverse threaded screw is rotatably connected to the inner wall of the rectangular slide groove.

[0010] Preferably, a guide slider is slidably connected inside the slide groove, and each guide slider has a sliding hole. The guide slider is movably sleeved on the outer wall of the guide rod through the sliding hole. A movable slider is slidably connected inside the rectangular slide groove, and a threaded sleeve is fixedly installed on one side of the outer wall of the movable slider.

[0011] A guide slider is installed, which works in conjunction with the guide rod to allow the moving platform to slide along a fixed trajectory during movement. This coordination effectively avoids instability such as shaking or deviation during movement, ensuring stability during bolt clamping operations and improving the accuracy of bolt inspection. In the centering and clamping moving part, the guide slider works in conjunction with the forward threaded screw, the reverse threaded screw, and the moving slider. When the motor drives the screw to rotate, the moving slider moves the moving platform, while the guide slider plays an auxiliary and guiding role, ensuring that the two moving platforms can move relative to each other to achieve centering and clamping of the bolt, improving the device's adaptability to bolts of different specifications and clamping accuracy.

[0012] Preferably, the movable slider is threadedly connected to the forward threaded screw and the reverse threaded screw respectively via threaded sleeves, and the top outer walls of the movable slider and the guide slider are respectively fixedly mounted with movable platform one and movable platform two.

[0013] Preferably, the adaptive clamping part specifically includes: a fixing block, which is fixedly installed on the top outer wall of the first mobile platform and the second mobile platform respectively; each fixing block has an installation port, a fixing support frame is fixedly installed on one side of the outer wall of the fixing block, and an electric telescopic rod is fixedly installed inside the installation port.

[0014] An electric telescopic rod is installed, which can precisely control the extension length, thereby accurately adjusting the clamping force of the clamping block on the bolt. For bolts of different specifications and materials, it can prevent bolt damage due to excessive clamping force or loosening or displacement of the bolt during the inspection process due to insufficient clamping force. Through the control of the electric telescopic rod, in conjunction with components such as adaptive springs, connecting slides, clamping rubber contacts, and rubber protrusions, the clamping block can make a tighter and more stable contact with the bolt. The adaptive spring can make a certain degree of adaptive adjustment according to the shape and irregularity of the bolt surface, while the rubber contacts and protrusions increase the friction between the bolt and the bolt, further preventing the bolt from shaking or rotating during the inspection process and ensuring the smooth progress of the inspection.

[0015] Preferably, one end of the electric telescopic rod is fixedly installed inside the fixed support frame, and a clamping block is fixedly connected to the telescopic end of the electric telescopic rod. The clamping block has equidistant mounting grooves, and an adaptive spring is fixedly connected to the inner wall of the mounting groove. The other end of the adaptive spring is fixedly connected to a connecting slide rod, which is slidably connected to the mounting groove. A clamping rubber contact is fixedly installed at the other end of the connecting slide rod, and rubber protrusions are fixedly installed equidistantly on the outer circumference of the clamping rubber contact.

[0016] This utility model provides a clamping device for bolt inspection. It has the following advantages:

[0017] (1) This utility model, through the structure of guide fixing block, slide groove, guide rod, etc., can ensure the accuracy and stability of the moving slider and guide slider during the movement process, so that the moving platform one and moving platform two installed on it can accurately position the bolt in the center position, ensuring the accuracy and consistency of the detection. The design of the positive thread screw and the reverse thread screw allows the moving slider connected to it to move synchronously in both directions under the drive of the motor, so that the distance between the two moving platforms can be quickly adjusted according to the different sizes of the bolt, adapting to the centering and clamping requirements of bolts of various specifications, and improving the versatility and flexibility of the device.

[0018] (2) Through the design of the mounting groove, adaptive spring and connecting slide rod, the clamping rubber contact can be adaptively adjusted according to the shape and surface irregularity of the bolt. Whether the bolt is a standard part or has certain dimensional deviation or surface defects, it can achieve a tight fit, ensuring the stability and reliability of clamping. The clamping rubber contact and the rubber protrusions fixedly installed at equal intervals on its outer circumference provide sufficient friction to prevent the bolt from sliding while effectively avoiding damage to the bolt surface. The electric telescopic rod can flexibly adjust the position of the clamping block according to the length and diameter of the bolt, enhancing the versatility of the clamping device.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0026] Addressing the current problems of difficulty in clamping bolts of different specifications, inability to adapt to different bolt shapes and surface conditions, and easy damage to the bolt surface affecting post-inspection use, this utility model provides a preferred embodiment of a bolt inspection clamping device, for example... Figures 1-4 As shown: A clamping device for bolt detection includes a support fixing plate 1, a centering clamping moving part 3, and an adaptive clamping part 4. Support fixing legs 2 are symmetrically fixedly installed on the bottom outer wall of the support fixing plate 1, and support pads are fixedly installed on the bottom outer wall of the support fixing legs 2. The centering clamping moving part 3 is disposed on the top outer wall of the support fixing plate 1. The adaptive clamping part 4 is disposed on the top of the centering clamping moving part 3.

[0027] The centering clamping moving part 3 specifically includes: a guide fixing block 311, which is symmetrically fixedly installed on the top outer wall of the support fixing plate 1; a motor fixing bracket 314, which is fixedly installed on one side outer wall of the support fixing plate 1; and a rectangular fixing block 316, which is fixedly installed on the top outer wall of the support fixing plate 1.

[0028] The top outer wall of the guide fixing block 311 is provided with a sliding groove 312, and the inner walls of the sliding groove 312 are fixedly connected with guide rods 313. The motor fixing bracket 314 is fixedly installed with a motor 315 inside. The top outer wall of the rectangular fixing block 316 is provided with a rectangular sliding groove, and the output end of the motor 315 is fixedly connected with a positive threaded screw 317.

[0029] The other end of the positive threaded screw 317 moves through the outer wall of the rectangular fixed block 316 and extends into the interior of the rectangular slide groove. The other end of the positive threaded screw 317 is fixedly connected to a connecting rod 318, and the other end of the connecting rod 318 is fixedly connected to a reverse threaded screw 319. The other end of the reverse threaded screw 319 is rotatably connected to the inner wall of the rectangular slide groove.

[0030] The slide groove 312 is slidably connected to a guide slider 3112. Each guide slider 3112 has a sliding hole. The guide slider 3112 is movably sleeved on the outer wall of the guide rod 313 through the sliding hole. The rectangular slide groove is slidably connected to a movable slider 3113. A threaded sleeve is fixedly installed on one side of the outer wall of the movable slider 3113.

[0031] The movable slider 3113 is threadedly connected to the forward threaded screw 317 and the reverse threaded screw 319 respectively through threaded sleeves. The top outer walls of the movable slider 3113 and the guide slider 3112 are respectively fixedly installed with the movable platform 1 3111 and the movable platform 2 3114.

[0032] In this embodiment, the motor 315 is started, and the output end of the motor 315 drives the forward threaded screw 317 to rotate. Since the forward threaded screw 317 and the moving slider 3113 are connected by a threaded sleeve, and the other end of the forward threaded screw 317 is connected to the reverse threaded screw 319 through a connecting rod 318, and the reverse threaded screw 319 is also threadedly connected to the moving slider 3113, the moving slider 3113 moves linearly along the forward threaded screw 317 and the reverse threaded screw 319 in the rectangular slide groove. At the same time, the guide slider 3112 slides along the guide rod 313 in the slide groove 312 on the top outer wall of the guide fixing block 311, and moves synchronously with the moving slider 3113. This causes the moving platform 1 3111 and the moving platform 2 3114 to move closer or further apart, adjusting to a suitable spacing position for the bolt to be tested. The distance between the two moving platforms can be quickly adjusted according to the different sizes of the bolts, adapting to the centering and clamping requirements of various specifications of bolts, and improving the versatility and flexibility of the device. Example

[0033] Please see Figures 1-4 Furthermore, based on Embodiment 1, the adaptive clamping part 4 specifically includes: a fixing block 411, which is fixedly installed on the top outer wall of the first mobile platform 3111 and the second mobile platform 3114 respectively; each fixing block 411 is provided with an installation port 412, and a fixing support frame 413 is fixedly installed on one side outer wall of the fixing block 411, and an electric telescopic rod 414 is fixedly installed inside the installation port 412.

[0034] One end of the electric telescopic rod 414 is fixedly installed inside the fixed support frame 413. The telescopic end of the electric telescopic rod 414 is fixedly connected to a clamping block 415. The clamping block 415 is provided with mounting grooves 416 at equal intervals. An adaptive spring 417 is fixedly connected to the inner wall of the mounting groove 416. The other end of the adaptive spring 417 is fixedly connected to a connecting slide rod 418. The connecting slide rod 418 is slidably connected to the mounting groove 416. The other end of the connecting slide rod 418 is fixedly installed with a clamping rubber contact 419. Rubber protrusions 4111 are fixedly installed at equal intervals on the outer circumference of the clamping rubber contact 419.

[0035] In this embodiment, the electric telescopic rod 414 is activated and extends out of the mounting opening 412 of the fixing block 411, pushing the clamping block 415 closer to the bolt. When the clamping rubber contact 419 contacts the bolt surface, due to the possibility of irregular shape or size deviation on the bolt surface, the adaptive spring 417 is compressed in the mounting groove 416, and the connecting slide rod 418 slides in the mounting groove 416, so that the clamping rubber contact 419 can adaptively fit the bolt surface. The rubber protrusions 4111 on its outer circumference increase the friction, achieving stable clamping of the bolt. It provides sufficient friction to prevent the bolt from slipping while effectively avoiding damage to the bolt surface. The electric telescopic rod can flexibly adjust the position of the clamping block according to the length and diameter of the bolt, enhancing the versatility of the clamping device.

[0036] Working principle: When in use;

[0037] Step 1: Place the support plate 1 on a stable workbench, and ensure that the support pad at the bottom of the support leg 2 is in contact with the workbench to ensure that the device is stable. Check whether the components of the centering clamping moving part 3 and the adaptive clamping part 4 are installed firmly, and whether the wiring connection of the motor 315 and the electric telescopic rod 414 is correct and the power supply is normal.

[0038] Step 2: Start the motor 315. The output end of the motor 315 drives the positive threaded screw 317 to rotate. Since the positive threaded screw 317 is connected to the moving slider 3113 by a threaded sleeve, and the other end of the positive threaded screw 317 is connected to the reverse threaded screw 319 by a connecting rod 318, and the reverse threaded screw 319 is also threadedly connected to the moving slider 3113, the moving slider 3113 moves linearly along the positive threaded screw 317 and the reverse threaded screw 319 in the rectangular groove. At the same time, the guide slider 3112 slides along the guide rod 313 in the groove 312 on the top outer wall of the guide fixing block 311, and moves synchronously with the moving slider 3113, thereby driving the moving platform 1 3111 and the moving platform 2 3114 to move closer or further apart, and adjust to a suitable spacing position for the bolt to be tested.

[0039] Step 3: Place the bolt to be tested between moving platform 1 3111 and moving platform 2 3114, so that the bolt is roughly in the center position;

[0040] Step 4: Activate the electric telescopic rod 414. The electric telescopic rod 414 extends out of the mounting opening 412 of the fixing block 411, pushing the clamping block 415 closer to the bolt. When the clamping rubber contact 419 contacts the bolt surface, due to the possible irregular shape or size deviation of the bolt surface, the adaptive spring 417 is compressed in the mounting groove 416, and the connecting slide rod 418 slides in the mounting groove 416, so that the clamping rubber contact 419 can adaptively fit the bolt surface. The rubber protrusions 4111 on its outer circumference increase the friction, achieving stable clamping of the bolt.

[0041] Step 5: After the bolt clamping is completed, the bolt can be subjected to corresponding inspections, such as dimensional measurement, appearance inspection, and mechanical performance testing. During the inspection process, the centering clamping moving part 3 and the adaptive clamping part 4 continuously maintain a stable clamping state on the bolt to ensure the accuracy of the inspection results.

[0042] Step Six: After the inspection is completed, the electric telescopic rod 414 retracts, causing the clamping block 415 to move away from the bolt and release the clamp. Then, the motor 315 is restarted to move the moving platform 1 3111 and the moving platform 2 3114 away from each other, making it easier to remove the inspected bolt and prepare for the next inspection operation.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
