DETAILED DESCRIPTION
[0026] 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.
[0027] In the present disclosure, unless otherwise specified, the directions or positional relationships indicated by directional words such as "up", "down", "left", and "right" are defined based on the drawing directions shown in the corresponding drawings and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation. Therefore, they cannot be understood as limitations on the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.
[0028] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.
[0029] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0030] like Figure 1 and Figure 2As shown, the present disclosure provides a vehicle body positioning hole correction device, including a first correction piece 10 and a second correction piece 20, the first correction piece 10 includes a first main body 11 and a first correction part 12 arranged on the first main body 11, the second correction piece 20 includes a second main body 21 and a second correction part 22 arranged on the second main body 21, the first correction part 12 and the second correction part 22 are used to be respectively arranged on both sides of a vehicle body component formed with a vehicle body positioning hole, the first main body 11 can pass through the vehicle body positioning hole and be movably connected to the second main body 21, so that the first correction part 12 can move toward a direction close to the second correction part 22 and press the vehicle body component against the second correction part 22.
[0031] Through the above technical scheme, since the first main body 11 can pass through the vehicle body positioning hole and be movably connected to the second main body 21, and the first correction part 12 can move toward the direction close to the second correction part 22 under the action of the first main body 11 and press the vehicle body component with the vehicle body positioning hole against the second correction part 22, if the vehicle body positioning hole is deformed during the production process, the operator can directly operate the above vehicle body positioning hole correction device so that the vehicle body component with the vehicle body positioning hole can be clamped between the first correction part 12 and the second correction part 22 and subjected to the extrusion force from the first correction part 12 and the second correction part 22. In this way, the vehicle body structure with the vehicle body positioning hole can become flat under the extrusion action of the first correction part 12 and the second correction part 22, so that the vehicle body component with the vehicle body positioning hole can be restored to flatness, thereby realizing the correction of the vehicle body positioning hole.
[0032] Compared with the method in the related art in which the operator uses sheet metal tools to calibrate the vehicle body locating holes, the vehicle body locating hole correction device provided by the present invention calibrates the vehicle body locating holes by means of a first correction part 12 and a second correction part 22 respectively arranged on both sides of the vehicle body locating holes. The operator can extrude the vehicle body parts with the vehicle body locating holes by operating the first correction part 12 and the second correction part 22. The operator does not need to repeatedly operate the sheet metal tool to drag the vehicle body parts with the vehicle body locating holes to achieve the correction of the vehicle body locating holes. The correction of the vehicle body locating holes is relatively simple, and the correction efficiency of the vehicle body locating holes is high and the effect is good. After the vehicle body locating holes are corrected, the vehicle body parts with the vehicle body locating holes are not prone to unevenness, which effectively saves production and manufacturing costs. At the same time, it also effectively avoids the situation in which the operator is easily scratched by the sheet metal tool or the vehicle body parts with the locating holes during the correction of the vehicle body locating holes.
[0033] In addition, since the first correction part 12 and the second correction part 22 are respectively used to be set on both sides of the body part with the body locating hole, and the first main body 11 can pass through the body locating hole and be movably connected to the second main body 21, when calibrating the body locating hole, the operator can directly pass the above-mentioned first main body 11 through the body locating hole, and the first correction part 12 and the second correction part 22 can be respectively set on both sides of the body locating hole. The body locating hole can be corrected without disassembling the body. The body locating hole correction device is simple to disassemble and assemble, and the body locating hole correction efficiency is high.
[0034] The present disclosure does not limit the connection relationship between the first main body 11 and the second main body 21. As long as the first correction part 12 can move toward the direction close to the second correction part 22 under the action of the first main body 11, and the body part with the body positioning hole can be clamped between the first correction part 12 and the second correction part 22, as an embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the first main body 11 and the second main body 21 can be connected by threads. In this way, the first correction part 12 can be connected to the second correction part 22, and can move toward or away from the second correction part 22, so that the first correction part 12 and the second correction part 22 can be squeezed to form a body part with a body positioning hole, or the body positioning hole correction device can be taken out from the body positioning hole. The operation of the body positioning hole correction device is relatively simple, which effectively improves the correction efficiency of the body positioning hole.
[0035] In addition, since the first main body 11 and the second main body 21 are connected by threads, the threaded connection can play a self-locking role in the vehicle body positioning hole correction device, and the first main body 11 and the second main body 21 will not be disengaged due to the force of the vehicle body parts reacting on the first correction part 12 and the second correction part 22, which effectively avoids the first correction part 12 and / or the second correction part 22 being disengaged due to force when the operator releases the first correction part 12 and / or the second correction part 22, and the first correction part 12 and the second correction part 22 cannot continue to squeeze the vehicle body structure, resulting in the vehicle body positioning hole not being corrected in place or cannot be corrected.
[0036] The present disclosure does not limit the specific structures of the first correction member 10 and the second correction member 20, as long as the first correction member 10 and the second correction member 20 can cooperate with each other to achieve the correction of the vehicle body positioning hole. As an embodiment of the present disclosure, Figure 1 and Figure 2As shown, the second main body portion 21 includes a sleeve 211 and a nut 212, the second correction portion 22 is connected to the first end of the sleeve 211, the nut 212 is located at the second end of the sleeve 211, a through hole 221 is formed on the second correction portion 22, the first main body portion 11 can pass through the through hole 221 and the sleeve 211 in sequence and be circumferentially locked and axially movably connected to the sleeve 211, an external thread is formed on at least part of the outer circumferential surface of the first main body portion 11, the nut 212 is threadedly connected to the first main body portion 11 and constitutes a screw nut pair, and the nut 212 can abut against the second end of the sleeve 211.
[0037] In this way, the operator can move the first correction part 12 toward or away from the second correction part 22 by rotating the nut 212, so that the first correction part 12 and the second correction part 22 can extrude the body part with the body locating hole, or remove the body locating hole correction device from the body locating hole. The operation of the body locating hole correction device is relatively simple, which is conducive to improving the correction efficiency of the body locating hole.
[0038] In order to realize that the first main body 11 can be circumferentially locked and axially movably connected to the sleeve 211, optionally, as Figure 1 and Figure 2 As shown, the sleeve 211 is formed with a long hole 2111 extending axially of the sleeve 211 , a limited rotation hole 111 is formed on the first main body 11 , and the vehicle body positioning hole correction device also includes a limited rotation member 30 , which can pass through the long hole 2111 and be inserted into the limited rotation hole 111 . Since the limiting rotation member 30 can pass through the long hole 2111 formed on the sleeve 211 and be inserted into the limiting rotation hole 111 on the first main body 11, when the vehicle body positioning hole correction device is in use, the side surface of the limiting rotation member 30 can abut against the side wall of the long hole 2111, and the limiting rotation member 30 and the long hole 2111 can limit the first main body 11. In this way, when the nut 212 is rotated, the first main body 11 will not rotate with the rotation of the nut 212, and the first main body 11 can only move back and forth along the axial direction of the sleeve 211, so that the first correction part 12 moves toward or away from the second correction part 22, effectively avoiding the situation that when the vehicle body positioning hole device is in use, the first main body 11 rotates with the nut 212, the first correction part 12 cannot move toward or away from the second correction part 22, and the first correction part 12 and the second correction part 22 cannot clamp the vehicle body structure next to the vehicle body positioning hole.
[0039] The present disclosure does not limit the specific type and structure of the rotation limiting member 30 and the rotation limiting hole 111. As long as the rotation limiting member 30 and the rotation limiting hole 111 can cooperate with the long hole 2111 to limit the position of the first main body 11, it can be regarded as an embodiment of the present disclosure. Figure 1 and Figure 2As shown, the above-mentioned rotation-limiting member 30 can be a bolt, and the above-mentioned rotation-limiting hole 111 can be a threaded hole. In other words, the above-mentioned rotation-limiting member 30 can pass through the long hole 2111 formed on the sleeve 211 and be threadedly connected with the rotation-limiting hole 111. The rotation-limiting member 30 is reliably fixed on the first main body 11, which effectively avoids the situation in which the rotation-limiting member 30 falls off from the first main body 11 during the use of the vehicle body positioning hole correction device, the rotation-limiting member 30 and the long hole 2111 cannot limit the first main body 11, and the vehicle body positioning hole correction device cannot be used normally. As another embodiment, the above-mentioned rotation-limiting member can also be formed as a fixing pin, and the above-mentioned rotation-limiting hole 111 can also be formed as a pin hole.
[0040] The present disclosure does not limit the specific shapes of the first correction piece 10 and the second correction piece 20. In order to further improve the correction efficiency of the vehicle body positioning hole, optionally, as Figure 1 and Figure 2 As shown, the cross-sections of the first correction part 12, the second correction part 22, the first main body 11 and the sleeve 211 are all circular, the outer diameters of the first correction part 12 and the second correction part 22 are equal, and the outer diameters of the first correction part 12 and the second correction part 22 are both larger than the aperture of the vehicle body positioning hole, and the outer diameter of the first main body 11 is smaller than the outer diameter of the first correction part 12. Since the outer diameters of the first correction part 12 and the second correction part 22 are equal, and the outer diameters of the first correction part 12 and the second correction part 22 are both larger than the aperture of the vehicle body positioning hole, by reasonably adjusting the positions of the first correction part 12 and the second correction part 22 relative to the vehicle body positioning hole, the vehicle body positioning hole to be corrected can be completely covered by the first correction part 12 and the second correction part 22, so that the correction of the vehicle body positioning hole as a whole can be achieved with only one correction, and there is no need to repeatedly operate the vehicle body positioning hole correction device to perform multiple corrections on the vehicle body component formed with the vehicle body positioning hole, which effectively saves the correction time of the vehicle body positioning hole and improves the correction efficiency of the vehicle body positioning hole.
[0041] In addition, since the outer diameter of the first main body 11 is smaller than the outer diameter of the first correction part 12, when calibrating the vehicle body locating hole, the operator can pass the above-mentioned first main body 11 through the vehicle body locating hole, and can respectively arrange the first correction part 12 and the second correction part 22 on both sides of the vehicle body locating hole without disassembling the vehicle body. The operation of the vehicle body locating hole correction device is relatively simple, and the correction efficiency of the vehicle body locating hole is relatively high.
[0042] In order to facilitate the connection between the first body portion 11 and the nut 212, optionally, as Figure 1 and Figure 2 As shown, the first correction member 10 further includes a tapered portion 112 located at one end of the first body portion 11 away from the first correction portion 12. The tapered portion 112 can guide the first body portion 11, making it easier to insert the first body portion 11 into the sleeve 211 and / or the nut 212.
[0043] For the implementation scheme in which the above-mentioned second main body part 21 includes a sleeve 211 and a nut 212, an external thread is formed on at least a portion of the outer circumferential surface of the first main body part 11, and the first main body part 11 passes through the sleeve 211 and is connected to the nut 212, it can be understood that the above-mentioned external thread is formed on one end of the first main body part 11 close to the conical part 112 on the first main body part 11.
[0044] In order to facilitate the operator to operate the vehicle body positioning hole correction device to correct the vehicle body positioning hole, optionally, as Figure 1 and Figure 2 As shown, the body positioning hole correction device further includes a gripping member 40, which is connected to the second main body 21. In this way, when correcting the body positioning hole, the operator can hold the gripping member 40 with one hand and use the other hand to operate the auxiliary tool to rotate the nut 212, so that the first correction part 12 moves toward or away from the second correction part 22 under the action of the nut 212, thereby realizing the correction of the body positioning hole. The correction process of the body positioning hole is relatively small, the operation is simple, and there is no need for multiple people to operate at the same time, which effectively improves the correction efficiency of the body positioning hole and reduces the production and manufacturing costs of the vehicle.
[0045] The present disclosure does not limit the specific structure of the gripping rod 41, as long as the gripping rod 41 is convenient for the operator to hold. As an implementation method of the present disclosure, Figure 1 and Figure 2 As shown, the gripping member 40 includes a gripping rod 41 and a connecting rod 42, the connecting rod 42 includes a first section 421 and a second section 422, one end of the first section 421 is connected to the second main body 21, the other end of the first section 421 is connected to one end of the second section 422, the other end of the second section 422 is connected to the gripping rod 41, the extension direction of the first section 421 is set at an angle to the extension direction of the second main body 21, and the extension direction of the second section 422 is set at an angle to the extension direction of the first section 421. Since the gripping rod 41 is connected to the second main body 21 through the connecting rod 42, a lever structure with a certain length of force arm can be formed between the gripping rod 41 and the second main body 21, and the operator can stably grip the body positioning hole correction device without much effort, which effectively avoids the body positioning hole correction device being offset by force during the body positioning hole correction, and the body positioning hole correction is not in place or cannot be corrected.
[0046] In addition, since the extension direction of the first section 421 is set at an angle to the extension direction of the second main body 21, and the extension direction of the second section 422 is set at an angle to the extension direction of the first section 421, the shape and size of the holding rod 41 are adapted to the on-site processing conditions, which facilitates the operator to operate the body positioning hole correction device to correct the deformed body positioning hole.
[0047] In order to further avoid the situation that the gripping rod 41 slides during the body positioning hole correction, resulting in the body positioning hole being not corrected in place or being unable to be corrected. As an embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the outer diameter of the gripping rod 41 is larger than the outer diameter of the connecting rod 42, and anti-skid protrusions are provided on the outer circumference of the gripping rod 41. Since the anti-skid protrusions are provided on the outer circumference of the gripping rod 41, the friction of the gripping rod 41 is relatively large, which effectively prevents the gripping rod 41 and the operator's hand from sliding relative to each other when the operator grips the gripping rod 41, and the body positioning hole correction device from being displaced, resulting in the body positioning hole being not corrected in place or being unable to be corrected.
[0048] In addition, since the outer diameter of the connecting rod 42 is smaller than the outer diameter of the holding rod 41, by reasonably designing the dimensions of the connecting rod 42 and the holding rod 41, it is beneficial to reduce the weight of the vehicle body locating hole correction device while meeting the strength requirements of the holding rod 41. This is beneficial to the lightweight of the vehicle body locating hole correction device and can reduce the production and manufacturing costs of the vehicle body locating hole correction device.
[0049] 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.
[0050] 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.
[0051] 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.
