Description

Technical Field

[0001] This utility model relates to the field of workpiece force testing, and in particular to a clamp force measuring device. Background Technology

[0002] Clips are common mechanical parts or tools, typically serving functions such as fixing, clamping, limiting, or connecting, and are widely used in industrial manufacturing, daily life, electronic equipment, furniture assembly, and other fields. Force testing is required for clips during production testing.

However, manual operation makes it difficult to ensure the uniformity and stability of the clamping, leading to uncontrollable measurement errors. Furthermore, the clamps may fall off due to insecure fixation, posing a safety hazard. In addition, some technical workshops use wire hooks to hold the clamps and then measure directly; however, using wire for measurement is prone to breakage or detachment, making the measurement process somewhat dangerous.

[0041] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0042] Please refer to Figure 1 and Figure 2 A clamp force measuring device includes a driving device and a clamping device 1;

[0043] The driving device is connected to the input end of the clamping device 1.

[0044] The output end of the clamping device 1 has a first clamping surface 2 and a second clamping surface 3 for jointly clamping the card to be tested;

[0045] The first clamping surface 2 and the second clamping surface 3 are arranged opposite to each other, and the distance between the first clamping surface 2 and the second clamping surface 3 is adjustable to change the clamping force on the card to be tested.

[0046] As can be seen from the above description, the beneficial effects of this utility model are as follows: when measuring the force of the clamp, the clamp is clamped by the first clamping surface 2 and the second clamping surface 3 of the clamping device 1, and the drive device is activated to flexibly adjust the distance between the first clamping surface 2 and the second clamping surface 3, so as to ensure that the clamp is subjected to uniform and stable force during the measurement process, thereby improving the measurement accuracy. The test is then completed by obtaining the output of the drive device, ensuring operational safety.

[0047] Furthermore, the clamping device 1 includes clamp-shaped grippers;

[0048] The clamp-shaped gripper has two gripping forearms 11 and swinging rear arms 12 that correspond one-to-one with the gripping forearms 11. The first gripping surface 2 and the second gripping surface 3 are respectively located at the ends of the two gripping forearms 11 away from the swinging rear arms 12.

[0049] The drive unit is connected to the two swinging rear arms 12 via a transmission.

[0050] As described above, the clamp-like gripper design allows the swinging rear arm 12 to drive the clamping front arm 11 to open and close under the action of the drive device. This structure enables the first clamping surface 2 and the second clamping surface 3 to apply pressure symmetrically when clamping the clamp, further ensuring uniform force on the clamp and reducing measurement errors caused by uneven force.

[0051] Furthermore, it also includes a transition block 4, a first swing arm 5, and a second swing arm 6;

[0052] The adapter block 4 is provided with a first connecting shaft 14, and one end of the first swing arm 5 and one end of the second swing arm 6 are rotatably connected to the first connecting shaft 14.

[0053] The other end of the first swing arm 5 serves as the first traction end and is rotatably connected to one end of the swing rear arm 12 away from the clamping front arm 11.

[0054] The other end of the second swing arm 6 serves as the second traction end and is rotatably connected to one end of the other swing arm 12 away from the clamping forearm 11.

[0055] As described above, the transmission assembly consisting of the adapter block 4, the first swing arm 5, and the second swing arm 6 can effectively transmit the power of the drive device to the swinging rear arm 12. This transmission method can amplify the force and change its direction, allowing the drive device to drive the swinging rear arm 12 to produce a large swing amplitude with a small force, thereby flexibly adjusting the distance between the first clamping surface 2 and the second clamping surface 3. Simultaneously, the multiple rotating connection points ensure the flexibility and stability of the transmission process, ensuring the normal operation of the transmission assembly even under prolonged use or high stress, thus improving the overall reliability of the equipment.

[0056] Furthermore, there are at least two first swing arms 5;

[0057] One end of each of the first swing arms 5 is rotatably connected to the first connecting shaft 14, and the other end of each of the first swing arms 5 is connected to the second connecting shaft 15;

[0058] One end of the swinging rear arm 12 of the first swing arm 5, away from the clamping front arm 11, is rotatably connected to the second connecting shaft 15.

[0059] As described above, increasing the number of first swing arms 5 enhances the structural strength and load-bearing capacity of the transmission assembly. Multiple first swing arms 5 can evenly distribute the force transmitted to the swinging rear arm 12, preventing deformation or damage to a single swing arm due to excessive force and extending the equipment's service life. Furthermore, the coordinated operation of multiple first swing arms 5 makes the movement of the swinging rear arm 12 smoother, reducing swaying and vibration, further improving the precision of clamping force adjustment and ensuring the accuracy of measurement results.

[0060] Furthermore, there are at least two second swing arms 6;

[0061] One end of each second swing arm 6 is rotatably connected to the first connecting shaft 14, and the other end of each second swing arm 6 is connected to the third connecting shaft 16;

[0062] The end of the swing arm 12 of the second swing arm 6 that is away from the clamping forearm 11 is rotatably connected to the third connecting shaft 16.

[0063] As can be seen from the above description, similar to increasing the number of first swing arms 5, increasing the number of second swing arms 6 can further optimize the performance of the transmission components. Multiple second swing arms 6 can not only enhance the stability and reliability of the transmission, but also enable the two swinging rear arms 12 to maintain better synchronization during movement.

[0064] Furthermore, it also includes a pull ring 7;

[0065] The adapter block 4 has a through hole, the pull ring 7 passes through the through hole, and the driving device is connected to the pull ring 7.

[0066] As described above, the pull ring 7 facilitates the connection between the drive unit and the transmission assembly. Through the pull ring 7, the drive unit can be more easily connected and disconnected from the adapter block 4, simplifying equipment installation, debugging, and maintenance.

[0067] Furthermore, it also includes a force gauge;

[0068] The drive device is connected to the adapter block 4 via the force gauge.

[0069] As can be seen from the above description, the addition of a force gauge enables direct real-time monitoring of the force applied by the drive device, thereby accurately determining the clamping force of the clamp to be tested. At the same time, it allows the operator to precisely control the drive device and adjust it to a suitable clamping force according to the measurement requirements.

[0070] Furthermore, it also includes a top support and a card holder 8;

[0071] The top support and the card holder 8 are respectively disposed on the two swing rear arms 12, and the movable end of the top support is opposite to the card holder 8;

[0072] The length of the movable end of the top support is adjustable.

[0073] As described above, the top support and the holder 8 provide limiting and adjustment functions for the movement of the swinging rear arm 12. By adjusting the length of the movable end of the top support, the maximum opening and closing angle between the two swinging rear arms 12 can be precisely controlled, thereby limiting the maximum distance between the first clamping surface 2 and the second clamping surface 3.

[0074] Furthermore, the top support includes a screw mounting base 9 and a limiting screw 10;

[0075] The screw mounting base 9 is disposed on one of the swing rear arms 12, and the limiting screw 10 is disposed on the screw mounting base 9;

[0076] The bottom end of the limiting screw 10 is opposite to the card seat 8 located on the other swing arm 12.

[0077] As described above, the top support component, consisting of a screw mounting base 9 and a limiting screw 10, has a simple structure and is easy to adjust. Operators can easily change the distance between its bottom end and the mounting base 8 by rotating the limiting screw 10, thereby achieving precise adjustment of the length of the movable end of the top support component.

[0078] Furthermore, a contour block 13 is provided at one end of the clamping forearm 11 away from the swinging rear arm 12, and the first clamping surface 2 and the second clamping surface 3 are located on the contour block 13 in a one-to-one correspondence.

[0079] As described above, the contour block 13 can be adapted to the shape of the clamp, making the contact between the first clamping surface 2 and the second clamping surface 3 and the clamp more compact and fitted. This effectively prevents the clamp from sliding or shifting during measurement, further ensuring uniform force on the clamp and improving the accuracy and stability of the measurement.

[0080] Please refer to Figure 1 and Figure 2 Embodiment 1 of this utility model is as follows:

[0081] A clamp force measuring device includes a driving device and a clamping device 1; the driving device is connected to the input end of the clamping device 1; the output end of the clamping device 1 has a first clamping surface 2 and a second clamping surface 3 for jointly clamping the clamp to be tested; the first clamping surface 2 and the second clamping surface 3 are arranged opposite to each other, and the distance between the first clamping surface 2 and the second clamping surface 3 is adjustable to change the clamping force on the clamp to be tested.

[0082] In this embodiment, the clamping device 1 includes a clamp-shaped jaw; the clamp-shaped jaw has two clamping front arms 11 and swinging rear arms 12 corresponding to the clamping front arms 11 one by one, the first clamping surface 2 and the second clamping surface 3 are respectively located at the ends of the two clamping front arms 11 away from the swinging rear arms 12; the driving device is connected to the two swinging rear arms 12 in a transmission connection. Furthermore, it also includes a top abutment and a mounting base 8; the top abutment and the mounting base 8 are respectively disposed on the two swinging rear arms 12, the movable end of the top abutment is opposite to the mounting base 8; the length of the movable end of the top abutment is adjustable.

[0083] Combination Figure 1 As shown, the usage process of a clamp force measuring device is as follows:

[0084] First, the drive device controls the clamping device 1 to clamp and fix the clip between the first clamping surface 2 and the second clamping surface 3;

[0085] Then, adjust the top support so that it rests against the card holder 8, thereby limiting the minimum opening and closing angle of the two swinging rear arms 12, that is, controlling the maximum distance between the first clamping surface 2 and the second clamping surface 3; as long as the clamping device 1 maintains the top support relationship between the top support and the card holder 8, it can ensure that the clamp is in a clamped and fixed state.

[0086] Finally, the opening and closing angles of the two swinging rear arms 12 are controlled by the drive device, and the backing length of the top support is adjusted at the same time, so that the distance between the first clamping surface 2 and the second clamping surface 3 gradually decreases, that is, the clamping force is increased, and finally accurate strength data is safely obtained.

[0087] In this embodiment, the device further includes a transition block 4, a first swing arm 5, and a second swing arm 6; the transition block 4 is provided with a first connecting shaft 14, and one end of the first swing arm 5 and one end of the second swing arm 6 are rotatably connected to the first connecting shaft 14.

[0088] The other end of the first swing arm 5 serves as the first traction end and is rotatably connected to the end of a swinging rear arm 12 away from the clamping front arm 11; the other end of the second swing arm 6 serves as the second traction end and is rotatably connected to the end of another swinging rear arm 12 away from the clamping front arm 11. The transmission assembly also includes a pull ring 7; the adapter block 4 is provided with a through hole, through which the pull ring 7 passes, and the drive device is connected to the pull ring 7.

[0089] In this embodiment, the driving device can be a linear driving component such as a cylinder or a push-pull motor. Its movable end is connected to the pull ring 7 on the adapter block 4 through a force gauge. When measuring the force, the driving device pulls the pull ring 7 and converts the linear tension into the swing of the swing arm by means of the rotational connection. The first swing arm 5 and the second swing arm 6 gradually move closer together, and the two swing rear arms 12 also gradually move closer together, thereby increasing the clamping force of the two clamping front arms 11.

[0090] To improve stability, a contour block 13 is provided at the end of the clamping forearm 11 away from the swinging rear arm 12, with the first clamping surface 2 and the second clamping surface 3 located on the contour block 13 in a one-to-one correspondence.

[0091] Please refer to Figure 1 Embodiment two of this utility model is as follows:

[0092] A clamp force measuring device, based on the above-described embodiment one, comprises two first swing arms 5; one end of each first swing arm 5 is rotatably connected to a first connecting shaft 14, and the other end of each first swing arm 5 is connected to a second connecting shaft 15; the end of the swinging rear arm 12 of the corresponding first swing arm 5 away from the clamping front arm 11 is rotatably connected to the second connecting shaft 15. There are also two second swing arms 6; one end of each second swing arm 6 is rotatably connected to the first connecting shaft 14, and the other end of each second swing arm 6 is connected to a third connecting shaft 16; the end of the swinging rear arm 12 of the corresponding second swing arm 6 away from the clamping front arm 11 is rotatably connected to the third connecting shaft 16.

[0093] Please refer to Figure 1 Embodiment three of this utility model is as follows:

[0094] A clamp force measuring device, based on the above embodiment one or two, includes a top support component comprising a screw mounting base 9 and a limiting screw 10; the screw mounting base 9 is disposed on a swing rear arm 12, and the limiting screw 10 is disposed on the screw mounting base 9; the bottom end of the limiting screw 10 is opposite to the clamp seat 8 located on another swing rear arm 12.

[0095] In summary, the clamp force measuring device provided by this utility model clamps the clamp together with its first and second clamping surfaces during force measurement. A drive device flexibly adjusts the distance between the first and second clamping surfaces, ensuring uniform and stable force distribution on the clamp during measurement, thus improving measurement accuracy. Subsequent testing is completed by acquiring the output of the drive device, ensuring operational safety. The clamping device employs a clamp-like jaw design, which, under the action of the drive device, swings the rear arm to drive the clamping front arm to open and close. This structure allows the first and second clamping surfaces to apply pressure symmetrically when clamping the clamp, further ensuring uniform force distribution and reducing measurement errors caused by uneven force distribution. Furthermore, the transmission assembly consisting of the adapter block, the first swing arm, and the second swing arm effectively transmits the power of the drive device to the swinging rear arm. This transmission method amplifies and reverses the force, allowing the drive device to drive the swinging rear arm with a smaller force to produce a larger swing amplitude, thereby flexibly adjusting the distance between the first and second clamping surfaces. Meanwhile, the multiple rotating connection points ensure the flexibility and stability of the transmission process, ensuring the normal operation of the transmission components even under prolonged use or high stress, thus improving the overall reliability of the equipment.
