[0001] The present disclosure relates to the technical field of body-in-white, and in particular to a clamp and a dismantling device for a body-in-white. Background Art
[0002] In the related art, in the destructive test of the body-in-white, it is necessary to use a clamp to clamp the parts to be disassembled of the body-in-white, and then use the clamp to tear the parts to be disassembled to expose the connection points to be tested. However, after the current clamp bites the parts to be disassembled, it is still necessary to manually assist the clamp to clamp the parts to be disassembled, that is, the current clamp cannot automatically clamp the parts to be disassembled after biting the parts to be disassembled, which reduces the disassembly efficiency of the body-in-white. Utility Model Content
[0003] The purpose of the present invention is to provide a clamp which can solve the technical problem that the parts to be disassembled cannot be automatically clamped after the parts to be disassembled are bitten.
[0004] In order to achieve the above-mentioned purpose, the present invention provides a clamp, which includes a clamp body, a pre-tightening member and an elastic member, the clamp body having a jaw, the pre-tightening member being movably connected to the clamp body, the elastic member being arranged between the clamp body and the pre-tightening member, and making the pre-tightening member abut against an end of the clamp body away from the jaw, when the jaw is opened, the elastic member is pulled or compressed, and is applied to the clamp body through the pre-tightening member, so that the jaw has a pre-tightening force that tends to become smaller.
[0005] Optionally, a stop portion is provided at one end of the preload member extending out of the pliers body, and the elastic member is provided between the pliers body and the stop portion, and the elastic member is compressed when the jaws are opened.
[0006] Optionally, the clamp includes a pressure plate, which is sleeved on the preload member and arranged between the clamp body and the elastic member.
[0007] Optionally, the elastic member is configured as a compression spring, and the compression spring is sleeved on the preload member.
[0008] Optionally, the stop portion is formed with a hanging ring.
[0009] Optionally, the pliers body comprises two hinged sub-pliers, the sub-pliers having a receiving cavity and a limiting surface, the pre-tightening member having a limiting block, the limiting block being arranged in the receiving cavity and abutting against the limiting surface.
[0010] Optionally, the pliers body comprises two hinged sub-pliers, the sub-pliers are provided with a clamping plate, the clamping plate has a clamping surface for enclosing the jaws, and the clamping surface is configured as a wavy surface.
[0011] Optionally, the clamp is detachably connected to the split pliers.
[0012] According to a second aspect of the present disclosure, a dismantling device for a body-in-white is provided, comprising the clamp as described above.
[0013] Optionally, the disassembling device includes a lifting mechanism, the lifting mechanism includes a driving structure, a lifting rope and a hook, and the hook is connected to a lifting ring.
[0014] Optionally, the disassembling device includes a slide rail, and the driving structure is slidably connected to the slide rail along a horizontal direction.
[0015] Through the above technical solution, when the clamp provided by the present disclosure is used, the operator can hold the clamp body, and then push the pre-tightening member to move the pre-tightening member along the side close to the jaws. In this process, the elastic member is pulled or compressed to store elastic potential energy, and the pre-tightening member is released from the abutment with the clamp body, so that the clamp body can be allowed to rotate to avoid interference with the pre-tightening member when the clamp body rotates. Subsequently, the operator can rotate the clamp body to open the jaws, and after operating the clamp body to bite the part to be disassembled, the operator can loosen the clamp body and the pre-tightening member. At this time, the elastic member releases the elastic potential energy, so that the pre-tightening member moves along the side away from the jaws and abuts against the clamp body, and the pre-tightening member applies a pre-tightening force to the clamp body that makes the jaws have a tendency to become smaller. Therefore, this part of the pre-tightening force can be used to make the clamp body automatically clamp the part to be disassembled, thereby solving the technical problem that the clamp cannot automatically clamp the part to be disassembled after biting the part to be disassembled. In addition, when the clamps disclosed in the present invention are used for disassembling the body-in-white, operators are not required to assist the clamps in clamping the parts to be disassembled, thereby reducing labor input, reducing costs, and improving the disassembly efficiency of the body-in-white.

DETAILED DESCRIPTION
[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0024] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" are used based on Figure 1 For details, please refer to Figure 1 In addition, the up and down direction may also correspond to the gravity direction of the disassembly and assembly device. "Inside and outside" refer to the inside and outside of the contour of each component. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements, and this disclosure will not repeat them.
[0025] According to some embodiments of the present disclosure, a clamp is provided, referring to Figure 2 and Figure 3 As shown in the figure, the clamp includes a clamp body 1, a preload 2 and an elastic member 3. The clamp body 1 has a jaw 11. The preload 2 is movably connected to the clamp body 1. The elastic member 3 is arranged between the clamp body 1 and the preload 2, and the preload 2 is abutted against the end of the clamp body 1 away from the jaw 11. When the jaw 11 is opened, the elastic member 3 is pulled or compressed, and is applied to the clamp body 1 through the preload 2, so that the jaw 11 has a preload force that tends to become smaller.
[0026] Through the above technical solution, when the clamp provided by the present disclosure is used, the operator can hold the clamp body 1, and then push the preload 2 to move the preload 2 along the side close to the jaw 11. In this process, the elastic member 3 is pulled or compressed to store elastic potential energy, and the preload 2 is released from the abutment with the clamp body 1, so that the clamp body 1 can be allowed to rotate to avoid interference with the preload 2 when the clamp body 1 rotates. Subsequently, the operator can rotate the clamp body 1 to open the jaw 11, and after operating the clamp body 1 to bite the part to be disassembled, the operator can loosen the clamp body 1 and the preload 2. At this time, the elastic member 3 releases the elastic potential energy, so that the preload 2 moves along the side away from the jaw 11 and abuts against the clamp body 1, and the preload 2 applies a preload force to the clamp body 1 that makes the jaw 11 have a tendency to become smaller. Therefore, this part of the preload force can make the clamp body 1 automatically clamp the part to be disassembled, thereby solving the technical problem that the clamp cannot automatically clamp the part to be disassembled after biting the part to be disassembled. In addition, when the clamp of the present disclosure is used to dismantle the body-in-white 100 , an operator does not need to use the auxiliary clamp to clamp the parts to be disassembled, thereby reducing labor input, reducing costs, and improving the disassembly efficiency of the body-in-white 100 .
[0027] It should be noted that the pliers body 1 may include two hinged pliers 12, and the preload member 2 may move in a direction perpendicular to the hinge axis of the two pliers 12, which is not limited in the present disclosure. Figure 2 As shown in the figure, the split clamp 12 can have a receiving cavity (not shown in the figure) and a limiting surface 121, and the pre-tightening member 2 can have a limiting block 22, which is arranged in the receiving cavity and abuts against the limiting surface 121. Here, by using the cooperation between the limiting block 22 and the receiving cavity, the pre-tightening member 2 can be movably connected with each split clamp 12, which has a simple structure and high reliability. In addition, the abutment of the limiting block 22 and the limiting surface 121 can realize that the elastic member 3 transfers the pre-tightening force to each split clamp 12 through the limiting surface 121.
[0028] It should also be noted that when the above-mentioned jaws 11 are closed, the elastic member 3 can also be pulled or compressed, and then a pre-tightening force is applied to the pliers body 1 through the pre-tightening member 2 so that the jaws 11 have a tendency to become smaller. Therefore, even if the jaws 11 are very small, the pliers body 1 can automatically clamp the parts to be disassembled, thereby improving the reliability of the clamps.
[0029] In some embodiments of the present disclosure, reference Figure 2As shown in , the end of the preload member 2 extending out of the pliers body 1 may be provided with a stopper 21, and the elastic member 3 is provided between the pliers body 1 and the stopper 21. When the jaws 11 are opened, the elastic member 3 is compressed. In this way, the elastic member 3 may be provided on the outside of the pliers body 1. On the one hand, it is convenient for the assembly of the clamp. On the other hand, when the pliers body 1 clamps the part to be disassembled, the elastic member 3 may make the stopper 21 and the pliers body 1 tend to move away from each other. Thus, when the pliers are suspended by using the stopper 21, the stopper 21 and the pliers body 1 may also move away from each other due to the effect of gravity. Therefore, such a setting will not interfere with the automatic clamping of the pliers body 1 on the part to be disassembled. Here, in some embodiments, reference is made to Figure 2 As shown in , the stopper 21 may be formed with a lifting ring 211 , so that the baffle clamp is hooked with the hook 203 in the disassembling device.
[0030] In other embodiments of the present disclosure, reference Figure 2 As shown in , the clamp may include a pressure plate 4 connected to the clamp body 1, and an elastic member 3 is arranged inside the clamp body 1 and connected between the preload member 2 and the pressure plate 4. When the jaws 11 are opened, the elastic member 3 is pulled. In this way, when the clamp body 1 bites the part to be disassembled, the elastic member 3 can apply a preload force to the preload member 2 so that the preload member 2 has a preload force away from the jaws 11. The preload force can be transmitted to the clamp body 1, so that the jaws 11 has a preload force that tends to become smaller, thereby, the automatic clamping of the clamp body 1 on the part to be disassembled can also be achieved. Here, the present disclosure only takes the example of the elastic member 3 being arranged between the clamp body 1 and the stopper 21 for illustrative introduction.
[0031] In some embodiments of the present disclosure, reference Figure 2 As shown in , the clamp may include a pressing plate 4, which is sleeved on the preload member 2 and arranged between the clamp body 1 and the elastic member 3. In this way, the clamp can prevent the elastic member 3 from directly abutting against the clamp body 1, and prevent the clamp body 1 from generating friction with the elastic member 3 when the clamp body 1 rotates, thereby improving the reliability of the clamp. Here, the preload member 2 can move relative to the pressing plate 4, and the pressing plate 4 can be detachably arranged on the clamp body 1, which is not limited by the present disclosure.
[0032] In some embodiments of the present disclosure, reference Figure 2 As shown in , the elastic member 3 is constructed as a compression spring, and the compression spring is sleeved on the preload member 2. In this way, the elastic member 3 can be prevented from moving in a direction perpendicular to its own axis, thereby improving the stability of the elastic member 3 when in use, thereby also improving the reliability of the clamp.
[0033] In some embodiments of the present disclosure, reference Figure 2 and Figure 3As shown in the figure, the pliers body 1 may include two hinged split pliers 12, and a clamping plate 5 may be provided on the split pliers 12. The clamping plate 5 has a clamping surface 51 for surrounding the jaws 11, and the clamping surface 51 is configured as a wavy surface. In this way, the wavy surface can be used to increase the friction between the split pliers 12 and the parts to be disassembled, thereby preventing the pliers body 1 from accidentally separating from the parts to be disassembled. Of course, in other embodiments, knurling can also be provided on the clamping plate 5 to increase the friction between the split pliers 12 and the parts to be disassembled.
[0034] In some embodiments of the present disclosure, the clamp 5 is detachably connected to the splitter 12. In this way, the clamp 5 can be replaced in time. In some embodiments, a countersunk hole can be provided on the clamp 5, and the threaded fastener can be threadedly connected to the splitter 12 through the countersunk hole, thereby realizing the detachable connection between the clamp 5 and the splitter 12, which has a simple structure and high reliability. Here, the threaded fastener can be arranged on the inner side of the clamping surface 51, that is, it does not protrude from the clamping surface 51, so as to avoid interference between the threaded fastener and the parts to be disassembled. Of course, in other embodiments, one of the clamp 5 and the splitter 12 can be provided with a buckle, and the other can be provided with a slot. The detachable connection between the clamp 5 and the splitter 12 can also be realized by the clamping connection between the buckle and the slot.
[0035] In some embodiments of the present disclosure, reference Figure 3 As shown in , when the jaws 11 are opened, the maximum spacing distance A between the two clamping plates 5 can be 25 mm to 35 mm, for example, 30 mm, which is not limited in the present disclosure.
[0036] In some embodiments of the present disclosure, reference Figure 2 and Figure 3 As shown in the figure, an avoidance groove 13 may be formed between the two split jaws 12, and the avoidance groove 13 is connected to the jaws 11 to avoid the parts to be disassembled. In some embodiments, the avoidance groove 13 may be configured as a rectangular groove, the length of the rectangular groove may be 25 mm to 35 mm, for example, 30 mm, and the width of the rectangular groove may be 25 mm to 35 mm, for example, 30 mm, and the present disclosure does not limit this.
[0037] According to a second aspect of the present disclosure, a disassembly device for a body-in-white is provided, comprising the clamp 10 as described above. The disassembly device has all the beneficial effects of the clamp as described above, which will not be described in detail in the present disclosure.
[0038] In some embodiments of the present disclosure, reference Figure 1As shown in , the disassembly device includes a lifting mechanism 20, and the lifting mechanism 20 may include a driving structure 201, a lifting rope 202 and a hook 203, and the hook 203 is connected to the lifting ring 211. In this way, the driving structure 201 can be used to lift and lower the clamp, so that when the corresponding parts to be disassembled on the body-in-white 100 need to be disassembled, the clamp can be first clamped to the parts to be disassembled, and then the clamp can be raised, so that the parts to be disassembled can be torn apart, exposing the connection points to be tested. Here, in some embodiments, the lifting mechanism 20 can be constructed as an electric hoist, which is not limited by the present disclosure.
[0039] In some embodiments of the present disclosure, reference Figure 1 As shown in , the disassembling device may include a slide rail 30, and the driving structure 201 is slidably connected to the slide rail 30 in the horizontal direction. In this way, the driving mechanism can achieve horizontal movement, thereby utilizing the disassembly range of the disassembling device. Here, the disassembling device may include a suspension beam 40, and the slide rail 30 may be connected to the suspension beam 40, which is not limited in the present disclosure.
[0040] Next, the present disclosure will introduce the specific use process of the disassembling device in detail in combination with the above specific embodiments. Figures 1 to 3 As shown in , first, the operator can hold the pliers body 1, and then push the preload 2 to move the preload 2 along the side close to the jaws 11. During this process, the elastic member 3 is compressed, storing elastic potential energy, and the preload 2 is released from the abutment with the pliers body 1. Then, the operator can rotate the pliers body 1 to open the jaws 11. After operating the pliers body 1 to bite the parts to be disassembled, the operator can release the pliers body 1 and the preload 2. At this time, the elastic member 3 releases the elastic potential energy, so that the pliers body 1 automatically clamps the parts to be disassembled. After that, the lifting ring 211 is hung on the hook 203, and then the clamp is raised to tear open the parts to be disassembled and expose the connection points to be tested.
[0041] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0043] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
