Description

Technical Field

[0001] This utility model relates to the field of calibration for bolt and nut torque connection simulators, and more particularly to a calibration device for bolt and nut torque connection simulators. Background Technology

[0002] Bolts and nuts are the most commonly used fasteners in the mechanical field. They are used for mechanical connections, load transmission, positioning, and guidance, and their applications are extremely wide-ranging. Therefore, during the manufacturing process of bolts and nuts, various tests are required to prevent breakage and other problems during use, which could lead to property damage or personal safety issues.

[0003] In existing technologies, bolt and nut torque connection simulators use calibration devices to measure relevant data of the bolt and nut by fixing the bolt in a fixed seat and using a slide rail to move the nut on the bolt into the detection end. However, during the detection process, the nut needs to be twisted. When the nut is fully tightened, its torque is transmitted to the fixed seat. Over time, this may cause the fixed seat to twist, crack, or break, resulting in the bolt installed on the fixed seat not being in a horizontal position, thus making the detected data inaccurate.

[0004] Therefore, this application provides a calibration device for a bolt and nut torque connection simulator to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a calibration device for a bolt and nut torque connection simulator to solve the problem that existing fixed seats may twist or other difficult-to-detect situations under the influence of torque over a long period of time, which affects the accuracy of the test data.

[0006] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0007] A calibration device for a bolt and nut torque connection simulator includes:

[0008] Support base;

[0009] The movable component is slidably connected to the top of the support base via a slide rail. It has a bolt inside and a nut installed on the outside of the bolt. The movable component is used to drive the bolt and nut to move.

[0010] The moving part has a fixed base installed inside, and the fixed base includes a detection mechanism that can slide up and down along the fixed base;

[0011] The detection mechanism includes a sliding member and a lifting rod fixedly connected to the top of the sliding member. The sliding member has a rectangular cavity inside and several sliding grooves that penetrate the top and communicate with the rectangular cavity. The sliding member is provided with several detection rods that are slidably connected to the side wall. One end of each detection rod is located in the rectangular cavity and extends upward into the corresponding sliding groove to form a sliding rod. The other end extends to the outside of the sliding member and is rotatably connected to a corresponding rotating cylinder. The detection mechanism is used to detect the flatness of the inner wall of the fixed seat.

[0012] Preferably, a limiting component is fixedly connected to the bottom wall of the rectangular cavity, and an elastic component is fixedly connected to one end of each of the plurality of detection rods located in the rectangular cavity, and the ends of the plurality of elastic components away from the detection rods are fixedly connected to the outer wall of the limiting component.

[0013] Preferably, a plurality of the detection rods are evenly distributed on the four sides of the sliding member.

[0014] Preferably, a plurality of the rotating cylinders are located between the inner wall of the fixed seat and the outer wall of the sliding member and rotate laterally, and all the rotating cylinders form a continuous rectangle in contact with the inner wall of the fixed seat.

[0015] Preferably, the top of the slide bar is lower than the top of the slider and is located within the slide groove.

[0016] Preferably, the fixing base further includes:

[0017] An anti-rotation insert plate, installed inside the mounting base and located on top of the sliding component, is used to prevent the bolt from rotating during the inspection process;

[0018] The inner baffle, installed inside the fixed base and located on top of the sliding element, is used to define the bolt position;

[0019] The outer baffle is installed on the outside of the fixing seat to support the bolts and ensure that the bolts are horizontal.

[0020] Preferably, it further includes:

[0021] The control unit, mounted on top of the support, is used to operate the entire calibration device.

[0022] Preferably, the control terminal includes:

[0023] The detection end, installed on the side of the control end near the moving part, is used to enclose the nut for detection and calibration of key parameters in the bolt and nut connection process.

[0024] This invention provides a calibration device for a bolt and nut torque connection simulator. Compared with the prior art, it has the following advantages:

[0025] 1. This calibration device uses a sliding detection mechanism installed inside the fixed base. The rotating drum in the detection mechanism forms a continuous rectangular contact with the inner wall of the fixed base. When the fixed base is twisted, cracked, or has debris due to torque, the corresponding rotating drum drives the sliding rod to slide in the groove. The operator can use this to determine whether there are defects on the inner wall of the fixed base and their specific locations, thus avoiding the problem of bolts not being installed horizontally due to deformation of the fixed base, thereby improving the accuracy of bolt and nut torque detection data.

[0026] 2. By evenly distributing several detection rods on the four sides of the sliding component, the rotating drum forms a continuous detection surface around the inner wall of the fixed seat, which can fully cover all areas of the inner wall of the fixed seat. Furthermore, by independently moving and providing feedback from the four detection rods, the specific location of the deformation of the inner wall of the fixed seat can be quickly located, facilitating targeted repair or replacement and improving equipment maintenance efficiency.

[0038] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0039] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0040] Example 1

[0041] Reference Figures 1-9 A calibration device for a bolt and nut torque connection simulator, comprising:

[0042] Support base 10;

[0043] The movable part 20 is slidably connected to the top of the support base 10 via a slide rail. A bolt 40 is provided inside the bolt 40, and a nut 41 is installed on the outside of the bolt 40. The movable part 20 is used to drive the bolt 40 and the nut 41 to move.

[0044] The movable part 20 has a fixed base 21 installed inside, and the fixed base 21 includes a detection mechanism that can slide up and down along the fixed base 21.

[0045] The testing mechanism includes a sliding member 25 and a lifting rod 26 fixedly connected to the top of the sliding member 25. A rectangular cavity 251 is opened inside the sliding member 25. Several sliding grooves 252 are opened through the top of the sliding member 25 and communicate with the rectangular cavity 251. Several testing rods 254 are slidably connected to the side wall of the sliding member 25. One end of the several testing rods 254 is located in the rectangular cavity 251 and extends upward into the corresponding sliding groove 252 to form a sliding rod 255. The other end extends to the outside of the sliding member 25 and is rotatably connected to the corresponding rotating cylinder 257. The testing mechanism is used to test the flatness of the inner wall of the fixed seat 21.

[0046] A limiting member 253 is fixedly connected to the bottom wall of a rectangular cavity 251. Several detection rods 254 are located at one end of the rectangular cavity 251 and are fixedly connected to elastic members 256. The ends of the elastic members 256 away from the detection rods 254 are fixedly connected to the outer wall of the limiting member 253.

[0047] Furthermore, such as Figure 6 and Figure 7 As shown, the elastic element 256 provides leeway for the movement of the detection rod 254, while also facilitating the return of the detection rod 254 to its original position.

[0048] Several detection rods 254 are evenly distributed on the four sides of the sliding member 25.

[0049] Furthermore, such as Figures 4 to 6 As shown, the movement of the detection rod 254 facilitates the detection of where a problem occurs on the inner wall of the fixed base 21.

[0050] Several rotating cylinders 257 are located between the inner wall of the fixed base 21 and the outer wall of the sliding member 25 and rotate laterally. All rotating cylinders 257 form a continuous rectangle in contact with the inner wall of the fixed base 21.

[0051] Furthermore, such as Figures 4 to 6 As shown, the rotating drum 257 is pressed tightly against the inner wall of the fixed seat 21, so that when the fixed seat 21 is twisted, cracked, or has debris due to torque or other reasons, the rotating drum 257 at the corresponding position can contact it.

[0052] The top of the slide bar 255 is lower than the top of the slider 25 and is located inside the slide groove 252.

[0053] Furthermore, such as Figure 7 As shown, this ensures that the top of the slider 25 always remains horizontal, preventing the top of the slider 255 from tilting under the action of the elastic element 256, which would affect the stability of the components set on the top of the slider 25.

[0054] Working process and principle: The operator lifts the lifting rod 26 upwards to check for twisting, debris, or other defects on the inner wall of the fixed seat 21. When twisting or debris is found at a certain location, the corresponding rotating cylinder 257 moves to that location and then moves towards the sliding member 25, causing the sliding rod 255 to slide within the sliding groove 252. The operator uses the sliding rod 255 to determine whether the fixed seat 21 is twisted or otherwise damaged, and can also determine the specific location.

[0055] Example 2

[0056] Reference Figures 1 to 3 and Figure 9 The mounting base 21 also includes:

[0057] Anti-rotation insert 22, installed inside the fixed base 21 and located on top of the sliding member 25, is used to prevent the bolt 40 from rotating during the inspection process;

[0058] The inner baffle 23 is installed inside the fixed base 21 and located on top of the sliding member 25 to define the position of the bolt 40;

[0059] The outer baffle 24 is installed on the outside of the fixed base 21 to support the bolt 40 and ensure that the bolt 40 is horizontal.

[0060] Also includes:

[0061] The control terminal 30 is mounted on the top of the support base 10 and is used to operate the entire calibration device.

[0062] Control terminal 30 includes:

[0063] The detection end 31 is installed on the side of the control end 30 near the moving part 20, and is used to wrap the nut 41 to detect and calibrate key parameters during the connection process of the bolt 40 and the nut 41.

[0064] Working process and principle: First, pass the bolt 40 through the inner baffle 23. Then, place the anti-rotation insert 22 on top of the bolt 40 nut and secure it. Fix the outer baffle 24 to the outside of the fixing base 21. Then, insert the bolt 40, inner baffle 23, and anti-rotation insert 22 together into the fixing base 21. At this time, if... Figure 3 As shown. Nut 41 is installed on bolt 40. Under the control of control terminal 30, moving part 20 moves towards control terminal 30, causing nut 41 to enter detection terminal 31. Control terminal 30 continues to operate, thereby detecting relevant data of bolt 40 and nut 41. After detection, they are removed sequentially.
