Technical Field

[0001] This application relates to the field of tooling technology, and more particularly to a tooling for a vehicle frame. Background Technology

[0002] Currently, some vehicle models use fiberglass composite materials for the front and rear body panels, which cannot be electrophoretically coated. Therefore, it is necessary to electrophoretically coat the frame separately before installing it with the fiberglass body panels. The frame consists of a front frame and a rear frame.

The skid frame is horizontally positioned, and multiple positioning components are provided and fixed to the skid frame. In use, the vehicle frame is placed directly on the skid frame, and then positioning components are welded around it for limiting and fixing.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: due to the flat placement of the frame, defects such as liquid accumulation and air pockets are easily formed inside the frame cavity, making it difficult for the electrophoretic solution to flow out and affecting the electrophoretic quality of the skeleton surface.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0041] This application discloses a tooling for a vehicle frame, referring to... Figure 1 , Figure 2The tooling used for the vehicle frame mainly includes a skid frame 1 and multiple suspension devices. The multiple suspension devices are spaced apart on the skid frame 1, and both the skid frame 1 and the suspension devices are made of steel. The suspension devices mainly include a base frame 2, multiple support rods 3, and multiple suspension beams 4. The bottom surface of the base frame 2 contacts the skid frame 1, and multiple fixing blocks 22 are also fixed to the bottom surface of the base frame 2. These fixing blocks 22 can be detachably connected to the skid frame 1 using bolts or other fasteners. To make the fixing blocks 22 more stable in relation to the skid frame 1, this embodiment uses double nuts for fixing, allowing the suspension devices and the skid frame 1 to be detachable, thus preventing damage to either and enabling the application to be used multiple times. Multiple support rods 3 are vertically attached to the bottom frame 2 and welded to the bottom frame 2. Multiple suspension beams 4 are parallel to the bottom frame 2 and welded to the end of the support rods 3 away from the bottom frame 2. The number of support rods 3 in a suspension device of this application is two, and the number of suspension beams 4 is two. The middle part of the suspension beam 4 is fixed to the top of the support rod 3. A reinforcing rod 44 is welded to the middle of the two suspension beams 4, thereby improving the stability of the two suspension beams 4.

[0042] Reference Figure 1 , Figure 2 , Figure 3 In use, the skid frame 1 is placed horizontally on the ground. The frame includes a front frame 9 and a rear frame 10. Multiple front frames 9 and rear frames 10 are suspended at intervals from the suspension beam 4. At this time, the front frames 9 and rear frames 10 are located in a vertical plane. Then, multiple suspension devices are placed at intervals on the skid frame 1, and the fixing block 22 is fixed to the skid frame 1 with bolts. In this application, two suspension devices are fixed on the skid frame 1. One suspension device in this application suspends two front frames 9 and two rear frames 10 respectively. This application places the front frame 9 and rear frame 10 vertically, reducing the occurrence of defects such as liquid accumulation and air cavities in the front frame 9 and rear frame 10, making it easier for the electrophoretic solution to flow out, and improving the electrophoretic quality of the surface of the front frame 9 and rear frame 10. At the same time, because the front frame 9 and rear frame 10 are placed vertically, the contact area between the front frame 9 and rear frame 10 and this application is reduced, further improving the electrophoretic quality of the front frame 9 and rear frame 10. This application also increases the number of suspension frames, improving work efficiency.

[0043] Reference Figure 4 , Figure 5To facilitate the separation of the front frame 9 and the rear frame 10, the suspension beam 4 is connected to multiple isolation components 5. These isolation components 5 are spaced apart on the suspension beam 4. One suspension device of this application has two isolation components 5, located on either side of the midpoint of the suspension beam 4. Each isolation component 5 includes a connecting rod 51 and multiple isolation rods 52. The connecting rod 51 is perpendicular to the suspension beam 4 and located on the same horizontal plane. The multiple isolation rods 52 are spaced apart from the connecting rod 51 and parallel to the support rod 3. The upper end of the connecting rod 51 extends out of the plane of the suspension beam 4. In use, the front frame 9 and the rear frame 10 are placed on either side of the isolation rods 52. The isolation rods 52 separate the front frame 9 and the rear frame 10, preventing them from connecting during electrophoresis, thereby improving the electrophoretic effect of the front frame 9 and the rear frame 10.

[0044] Reference Figure 4 , Figure 5 The isolation rod 52 is slidably connected to the connecting rod 51. The isolation assembly 5 also includes a fixing unit 53, which includes a sleeve 531 and a locking member 532. The sleeve 531 is welded and fixed to the connecting rod 51. The isolation rod 52 passes through the sleeve 531 and the connecting rod 51 and slides up and down in the inner cavity of the sleeve 531. The isolation rod 52 is connected and fixed to the sleeve 531 by the locking member 532. In use, before the user moves the front frame 9 and the rear frame 10 to the suspension beam 4, the isolation rod 52 is slid downward to facilitate the user moving the front frame 9 and the rear frame 10 to both ends of the isolation rod 52. Then the isolation rod 52 is slid upward and locked by the locking member 532, thereby separating the front frame 9 and the rear frame 10.

[0045] The locking element 532 is a wing bolt. The isolation rod 52 has a sliding hole 521 that penetrates the isolation rod 52 and extends along its height. The locking element 532 has two wing bolt caps and a screw. The screw passes through the sliding hole 521 and the sleeve 531. The two wing bolt caps are located at opposite ends of the screw. When the isolation rod 52 needs to be fixed, the two bolt caps are tightened, clamping the sleeve 531. The sleeve 531 undergoes a slight deformation, thus clamping and fixing the isolation rod 52, preventing it from sliding up and down. Alternatively, the locking element 532 can also be a bolt, which passes through the sleeve 531 and abuts against the isolation rod 52 for fixation.

[0046] To save production costs and reduce the weight of this application, the isolation rod 52 is tubular, and a sealing plate 54 is fixed to the bottom surface of the isolation rod 52. The sealing plate 54 is welded to the isolation rod 52, and the area of ​​the sealing plate 54 is greater than or equal to the area of ​​the tube opening of the isolation rod 52, thereby blocking the isolation rod 52 and preventing the dust layer in the isolation rod 52 from falling out of the isolation rod 52 and affecting the electrophoresis effect of the front frame 9 and the rear frame 10.

[0047] Reference Figure 4 , Figure 5 , Figure 6 The connecting rod 51 is located between two adjacent suspension beams 4 and its two ends are connected to the suspension beams 4 respectively. In this application, the connecting rod 51 has two isolation rods 52. The connecting rod 51 can be fixedly connected to the suspension beams 4, and the connecting rod 51 can also be slidably connected to the suspension beams 4. In this application, the connecting rod 51 is slidably connected to the suspension beams 4, and both ends of the connecting rod 51 are connected to sliding components 55. A sliding plate 42 is integrally formed on the opposing surfaces between two adjacent suspension beams 4, extending along the length of the suspension beams 4. The sliding components 55 are slidably connected to the sliding plate 42. In use, the user can adjust the position of the isolation rods 52 by sliding the connecting rod 51. Compared to adjusting the positions of the front frame 9 and the rear frame 10 at the suspension beams 4, the sliding configuration of the isolation rods 52 in this application makes movement easier.

[0048] The sliding assembly 55 includes a first roller 551 and a second roller 552 fixed to both ends of the connecting rod 51. Multiple first rollers 551 and second rollers 552 can be provided. In this application, two first rollers 551 and one second roller 552 are provided at one end of the connecting rod 51. The second roller 552 is located between the two first rollers 551 and below the first rollers 551. The first rollers 551 and second rollers 552 clamp the sliding plate 42. Both the first rollers 551 and second rollers 552 use bearings and are connected to both ends of the connecting rod 51 by bolts. The central axes of the first rollers 551 and second rollers 552 are parallel to the connecting rod 51. During sliding, both the first rollers 551 and second rollers 552 roll on the sliding plate 42, thereby displacing the connecting rod 51 at the suspension beam 4.

[0049] To make the sliding of the connecting rod 51 smoother, the sliding assembly 55 also includes a third roller 553. Multiple third rollers 553 are provided and fixed to the end side of the connecting rod 51 respectively. In this application, two third rollers 553 are fixed to both ends of the connecting rod 51 by bolts. The third rollers 553 are also bearings. The central axis of the third rollers 553 is parallel to the isolation rod 52. The third rollers 553 are in contact with the slide plate 42. The setting of the third rollers 553 reduces the probability of the connecting rod 51 tilting during the sliding process.

[0050] Reference Figure 4 , Figure 5The suspension beam 4 is also equipped with a first limiting component 6, which includes a limiting foot plate 61. The limiting foot plate 61 is connected to the suspension beam 4 and parallel to the support rod 3, with the upper end of the limiting foot plate 61 extending out of the plane where the suspension beam 4 is located. The front frame 9 or the rear frame 10 is located between the limiting foot plate 61 and the isolation rod 52, thereby restricting the sliding of the front frame 9 and the rear frame 10 at the suspension beam 4, facilitating the user to move the suspension device and improving the electrophoretic effect of the front frame 9 and the rear frame 10 in the later stage.

[0051] The upper end of the limiting foot plate 61 is bent toward the support rod 3 to form a bending part 611. In use, the front frame 9 or the rear frame 10 is located between the bending part 611 and the suspension beam 4, thereby restricting the upward movement of the front frame 9 or the rear frame 10, making the fixing of the front frame 9 and the rear frame 10 more precise, improving the convenience of transporting the suspension device and improving the electrophoresis effect of the front frame 9 and the rear frame 10.

[0052] Reference Figure 4 , Figure 5 The bent portion 611 is threadedly connected to a first locking handle 62. The first locking handle 62 passes through the bent portion 611 and abuts against and fixes the front frame 9 or the rear frame 10, thereby fixing the front frame 9 or the rear frame 10 against and fixing it to the suspension beam 4, thus preventing the front frame 9 or the rear frame 10 from moving at the suspension beam 4, thereby accurately positioning the front frame 9 or the rear frame 10.

[0053] The limiting foot plate 61 is slidably connected to the suspension beam 4. A slider is integrally formed at the lower end of the limiting foot plate 61. The suspension beam 4 has a groove 41 that fits the slider and extends along the length of the suspension beam 4. The slider of the limiting foot plate 61 is located within the groove 41. During installation, moving the limiting foot plate 61 causes the slider to move within the groove 41, thereby moving the limiting foot plate 61. This facilitates the installer's adjustment of the fixed position of the front frame 9 or rear frame 10 on the suspension beam 4. While the limiting foot plate 61 can also be fixed to the suspension beam 4, this application chooses a slidable connection between the limiting foot plate 61 and the suspension beam 4 to further improve the ease of installation for the installer.

[0054] Reference Figure 4 , Figure 7The support rod 3 is connected to a second limiting component 7, which includes a first support rod 71. The first support rod 71 is detachably connected to the support rod 3 and is parallel to the bottom frame 2. In this application, the first support rod 71 is located in the middle of the support rod 3, and its position can be adjusted. During use, the first support rod 71 is located in the middle of the front frame 9 or the rear frame 10 and supports the middle of the front frame 9 or the rear frame 10, thereby reducing the tilting or swaying of the front frame 9 or the rear frame 10 at the suspension beam 4, and providing better support for the front frame 9 or the rear frame 10.

[0055] A fixing member 72 is also provided on the section of the first support rod 71 away from the support rod 3. The upper end of the fixing member 72 extends out of the plane where the first support rod 71 is located. The fixing member 72 provides a barrier for the front frame 9 or the rear frame 10, thereby reducing the probability of the front frame 9 or the rear frame 10 detaching from the first support rod 71. The upper end of the fixing member 72 is also bolted with a first locking bolt 73. In use, the first locking bolt 73 passes through the fixing member 72 and abuts the front frame 9 or the rear frame 10 against the first support rod 71, thereby locking and fixing the fixing member 72 and preventing the front frame 9 or the rear frame 10 from detaching from the first support rod.

[0056] Reference Figure 4 , Figure 7 A sliding groove 711 is formed on the section of the first support rod 71 furthest from the support rod 3. The sliding groove 711 extends along the length of the first support rod 71, and the fixing member 72 is located in the sliding groove 711 and is slidably connected to the first support rod 71. During installation, this allows the installer to easily adjust the position of the fixing member 72, making the fixing of the front frame 9 or the rear frame 10 more accurate. The fixing member 72 can also be fixed to the first support rod 71, but this application chooses to slide the fixing member 72 to the first support rod 71, thereby improving the ease of installation for the installer of the front frame 9 or the rear frame 10.

[0057] Reference Figure 4 , Figure 7 The first support rod 71 is rotatably connected to the support rod 3. Multiple first limiting blocks 712 are integrally formed on the side of the first support rod 71, and the rotation plane of the first support rod 71 is a vertical plane. Before installation, the first support rod 71 is parallel to the support rod 3, which does not affect the installer's ability to move the front frame 9 or rear frame 10 to the suspension beam 4. After the front frame 9 or rear frame 10 is positioned at the suspension beam 4, the first support rod 71 is rotated so that it is perpendicular to the support rod 3. The first limiting blocks 712 restrict the rotation of the first support rod 71, and the middle part of the front frame 9 or rear frame 10 is located on the first support rod 71, thereby improving the installer's ease of installation. The first support rod 71 can also be bolted to the support rod 3, but this application uses a rotatable connection, which is more convenient for the installer.

[0058] The second limiting component 7 also includes a first connecting member 74, which is detachably connected to the support rod 3. The first connecting member 74 includes two connecting plates and two U-shaped reinforcing frames. The two connecting plates are located on opposite sides of the support rod 3 and are connected by bolts. The two U-shaped reinforcing frames are located between the two connecting plates and are respectively located on opposite sides of the support rod 3. The U-shaped reinforcing frames are welded and fixed to the connecting plates with their bottom surfaces facing the support rod 3, thereby increasing the strength of the connecting plates. The first connecting member 74 has a first limiting hole 741 adapted to the first limiting block 712. When rotation is not required, the multiple first limiting blocks 712 are located in the multiple first limiting holes 741, thereby restricting the rotation of the first support rod 71. When rotation is required, the first limiting blocks 712 are not in the first limiting holes 741, thus not limiting the first support rod 71 and facilitating its rotation.

[0059] To facilitate the installer's insertion of the first limiting block 712 into the first limiting hole 741, the first limiting block 712 has an integrally formed first guide portion 7121 on the side facing the first limiting hole 741. The first guide portion 7121 is arc-shaped and its width is smaller than that of the first limiting block 712, making it easier for the first limiting block 712 to be inserted into the first limiting hole 741.

[0060] The first support rod 71 also has a first positioning pin 713 integrally formed on its side. There are two first positioning pins 713 located on opposite sides of the first support rod 71. The first positioning pin 713 is located at the end of the first limiting block 712 facing the support rod 3. The first connecting member 74 has a first positioning hole 742, which is an elongated hole extending along the length of the first connecting member 74. The first positioning pin 713 is located in the first positioning hole 742 and slides within it. When the first support rod 71 needs to rotate, the first limiting block 712 disengages from the first limiting hole 741. At this time, the first positioning pin 713 is located at the end of the first positioning hole 742 away from the support rod 3, so that the first support rod 71 is still connected to the first connecting member 74. After rotation, the first positioning pin 713 moves towards the support rod 3 within the first positioning hole 742, thereby causing the first limiting block 712 to be positioned within the first limiting hole 741, making it easier for the first limiting block 712 to be inserted into the first limiting hole 741.

[0061] Reference Figure 4 , Figure 8 The bottom frame 2 is also provided with a third limiting component 8, which includes a second support rod 81 and a third support rod 82. The second support rod 81 is parallel to the support rod 3 and its bottom end is connected to the bottom frame 2. The top end of the second support rod 81 is connected to one end of the third support rod 82. The third support rod 82 is parallel to the bottom frame 2. During installation, the front frame 9 or the rear frame 10 is located at the third support rod 82, and the third support rod 82 supports the front frame 9 or the rear frame 10.

[0062] The third support rod 82 includes an outer tube 821 and an inner rod 822. One end of the outer tube 821 is connected to the second support rod 81, and the inner rod 822 is located inside the outer tube 821 and is slidably connected to it. The outer tube 821 has two guide holes 8211, which extend along the length of the outer tube 821 and are located on opposite sides of it. The inner rod 822 is connected to a second locking bolt 823. The second locking bolt 823 includes a threaded rod passing through the second guide hole 8211 and the inner rod 822, and nuts threaded at both ends. When it is necessary to position the inner rod 822 relative to the outer tube 821, the nuts are tightened, causing the two nuts to abut against and position the outer tube 821. The telescopic design of the third support rod 82 in this application facilitates the installer's adjustment of the length of the third support rod 82, allowing it to better support the front frame 9 or the rear frame 10.

[0063] Reference Figure 4 , Figure 8 The inner rod 822 has an integrally formed bending block 8221 at the end away from the second support rod 81. The upper end of the bending block 8221 protrudes from the plane of the inner rod 822. The bending block 8221 reduces the chance of the front frame 9 or rear frame 10 located at the third support rod 82 slipping off the third support rod 82. This facilitates later handling by the installer and improves the electrophoretic effect of the front frame 9 or rear frame 10. At the same time, the installer can adjust the length of the third support rod 82, so that the bending block 8221 and the second support rod 81 clamp the lower end of the front frame 9 or rear frame 10, further improving the fixation effect of the front frame 9 or rear frame 10.

[0064] The bending block 8221 is also threadedly connected to a second locking handle 8222. The second locking handle 8222 passes through the bending block 8221 and abuts against the front frame 9 or the rear frame 10, thereby making the front frame 9 or the rear frame 10 more stably fixed at the third support rod 82.

[0065] Reference Figure 8 The outer tube 821 is connected to a sliding sleeve 8212, which is welded and fixed to the outer tube 821. The sliding sleeve 8212 is fixed in a clamp-like shape by bolts. The sliding sleeve 8212 is fitted onto the second support rod 81 and is slidably connected to the second support rod 81. During installation, the installer can slide the sliding sleeve 8212 at the second support rod 81 to adjust the height of the third support rod 82, so that the third support rod 82 fits more closely with the front frame 9 or the rear frame 10. The outer tube 821 can also be fixed to the third support rod 82. This application adopts a sliding connection between the outer tube 821 and the third support rod 82, which makes it easier to fix the front frame 9 or the rear frame 10.

[0066] Reference Figure 4 , Figure 8The second support rod 81 is rotatably connected to the bottom frame 2. The second support rod 81 rotates in a vertical plane. A second limiting block 811 is integrally formed on the side of the second support rod 81, which restricts the rotation of the second support rod 81. Before the front frame 9 or the rear frame 10 is installed, the second support rod 81 is located in a horizontal plane. When the front frame 9 or the rear frame 10 is installed, the second support rod 81 is rotated so that the second support rod 81 is parallel to the support rod 3. The second support rod 81 is restricted from rotating by the second limiting block 811.

[0067] The third limiting assembly 8 also includes a second connecting member 83, which is detachably connected to the bottom frame 2. The bottom of the second connecting member 83 is in the shape of a clamp and is locked with bolts, thereby clamping and fixing the second connecting member 83 to the bottom frame 2. The upper end of the second connecting member 83 is open, and the second connecting member 83 also has a second limiting hole 831 adapted to the second limiting block 811. When the second support rod 81 rotates, the second limiting block 811 extends into the second limiting hole 831, thereby restricting the rotation of the second support rod 81.

[0068] To facilitate the installer's insertion of the second limiting block 811 into the second limiting hole 831, a second guide portion 8111 is integrally formed on the side of the second limiting block 811 facing the second limiting hole 831. The second guide portion 8111 is arc-shaped and its width is smaller than that of the second limiting block 811, making it easier for the second limiting block 811 to be inserted into the second limiting hole 831.

[0069] The side of the second support rod 81 passes through the second positioning pin 812. Two second positioning pins 812 are provided and located on opposite sides of the second support rod 81. The second positioning pin 812 is located at the end of the second limiting block 811 facing the second connector 83. The upper end of the second connector 83 has a second positioning hole 832, which is an elongated hole extending along the height direction of the second connector 83. The second positioning pin 812 is located in the second positioning hole 832 and slides within it. During installation, the second support rod 81 is inserted into the upper opening of the second connector 83, and then the second positioning pin 812 is passed vertically through the second positioning hole 832 and the second support rod 81. When the second support rod 81 needs to rotate, the second limiting block 811 disengages from the second limiting hole 831. At this time, the second positioning pin 812 is located in the second positioning hole 832, so that the second support rod 81 is still connected to the second connecting member 83. After the rotation is completed, the second positioning pin 812 moves towards one end of the support rod 3 in the second positioning hole 832, thereby driving the second limiting block 811 to be located in the second limiting hole 831, making it easier for the second limiting block 811 to be inserted into the second limiting hole 831.

[0070] Reference Figure 2 , Figure 4The bottom end of the base frame 2 is also welded with a limiting base 21 for connecting with a forklift. There are multiple limiting bases 21, and this application has four, with two as a group and the two groups are arranged opposite to each other. When it is necessary to move the suspension device, the forklift is inserted into the limiting base 21 to move the suspension device.

[0071] To facilitate the lifting of the suspension device by the crane, the suspension beam 4 is also fixed with a number of hooks 43 for hooking with the crane. This application has two hooks, which are welded to the two suspension beams 4 respectively.

[0072] The implementation principle of a tooling for a vehicle frame according to an embodiment of this application is as follows:

[0073] 1. Move the front frame 9 and the rear frame 10 to the suspension beam 4 so that the front frame 9 and the rear frame 10 are located on both sides of the isolation bar 52.

[0074] 2. Adjust the position of the connecting rod 51 at the suspension beam 4, and then adjust the position of the isolation rod 52 at the connecting rod 51 so that the upper end of the isolation rod 52 is higher than the upper end of the front frame 9 or the rear frame 10.

[0075] 3. Slide multiple limiting foot plates 61 so that the multiple limiting foot plates 61 contact the front frame 9 or the rear frame 10 respectively, and then position the front frame 9 or the rear frame 10 through the first locking handle 62.

[0076] 4. Rotate the first support rod 71 so that the first support rod 71 is perpendicular to the support rod 3, so that the middle part of the front frame 9 or the rear frame 10 is located at the first support rod 71, and fix the middle part of the front frame 9 or the rear frame 10 to the first support rod 71 by the fastener 72.

[0077] 5. Rotate the second support rod 81 so that the second support rod 81 is parallel to the support rod 3. Adjust the position of the third support rod 82 at the second support rod 81 so that the third support rod 82 and the front frame 9 or the rear frame 10 fall at the third support rod 82. Adjust the extension and retraction of the third support rod 82 so that the bending block 8221 and the support rod 3 clamp the front frame 9 or the rear frame 10. Then tighten and fix it with the second locking handle 8222.

[0078] 6. The forklift connects to the limit base 21 to move the suspension device to the skid frame 1. The forklift hooks the hook 43 to move the suspension device to the skid frame 1. Then, the bottom frame 2 is fixed to the suspension device with bolts.
