[0029] Automobile assembly is an important link in the automobile manufacturing process, which involves the process of assembling hundreds or thousands of parts into a complete vehicle and assemblies such as engines and transmissions according to specific technical requirements.

[0030] In the related art, taking the automobile door panel as an example, when installing parts on the automobile door panel, it is necessary to first fix the automobile door panel on the operating table by using a positioning mechanism, and then install them manually. However, traditional positioning mechanisms usually adopt profiling positioning or manual pressing positioning, with a single structure, unable to be compatible with parts of different sizes, and the clamping force cannot be controlled, thus greatly increasing the overall processing cost.

[0031] Please refer to Figures 1-5 , to solve the problem of poor compatibility caused by the single structure of the existing positioning and clamping tooling, the present application provides a positioning and clamping tooling 100, which is mainly used for clamping and positioning automobile parts, such as automobile door panels, etc., in order to facilitate the assembly with other various parts.

[0032] Specifically, the positioning and clamping tooling 100 of the present application includes a processing table 10, a driving mechanism 20, and a clamping mechanism 30. The processing table 10 includes multiple support legs 13, and a main board 11 and a bottom board 12 arranged at intervals along a first preset direction. Both the main board 11 and the bottom board 12 are fixedly connected to the support legs 13. A plurality of sliding grooves 1101 are formed on the main board 11, and the sliding grooves 1101 penetrate through the main board 11 along the first preset direction.

[0033] It should be noted that the first preset direction is the height direction of the processing table 10, that is, the thickness direction of the main board 11 and the bottom board 12.

[0034] Furthermore, as Figures 1-3 shown, the clamping mechanism 30 includes a plurality of clamping units 31. Each clamping unit 31 is installed in a corresponding one of the sliding grooves 1101 and can slide along the sliding grooves 1101. And a clamping space 301 for clamping automobile parts is formed by enclosing between the plurality of clamping units 31 and the main board 11. Among them, each clamping unit 31 at least partially extends out of the surface of the main board 11 close to the bottom board 12 through the sliding groove 1101. The driving mechanism 20 includes a first driving member 21, a turntable 22, and a plurality of adjusting rods 23. The first driving member 21 is installed on the bottom board 12. The turntable 22 is arranged between the main board 11 and the bottom board 12, and the turntable 22 is connected to the output end of the first driving member 21 and is used to rotate in response to the driving of the first driving member 21. And both ends of each adjusting rod 23 are respectively movably connected to the turntable 22 and the corresponding clamping unit 31. Among them, as the turntable 22 rotates, the adjusting rod 23 can drive the corresponding clamping unit 31 to slide along the corresponding sliding groove 1101 to adjust the size of the clamping space 301.

[0035] It can be understood that when the turntable 22 rotates, it can change the inclination angle of the adjusting rod 23 relative to the axis of the turntable 22. At this time, the adjusting rod 23 can apply a force to the clamping unit 31, prompting the clamping unit 31 to move along the sliding groove 1101, and multiple clamping units 31 can move synchronously to clamp and position the automotive parts located in the clamping space 301, making them not prone to shaking during the assembly process, effectively improving the stability during the assembly process, and thus greatly improving the assembly efficiency of automotive parts. At the same time, it can also accommodate the clamping of various automotive parts with different sizes on a positioning and clamping tooling 100, improving the versatility of the positioning and clamping tooling 100 and reducing costs.

[0036] Specifically, in this application, the number of clamping units 31 is two, and the two clamping units 31 are arranged on opposite sides of the main board 11 and enclose a clamping space 301 with the main board 11. In this way, the structure of the positioning and clamping tooling 100 is simple and easy to process, and it can effectively reduce the processing cost while ensuring the clamping effect.

[0037] In other embodiments, the number of clamping units 31 can also be reasonably set according to actual needs. For example, the clamping units 31 can also be set to three, four, five, etc., which will not be listed one by one here. It should be noted that here, the number of sliding grooves 1101 is preferably set to correspond one-to-one with the number of clamping units 31, and one end of the sliding groove 1101 extends and penetrates through the end of the main board 11 to facilitate the insertion and installation of the clamping unit 31.

[0038] To improve the stability of the clamping unit 31 when moving along the sliding groove 1101, in one embodiment, as Figure 1 shown, a limiting groove 1102 is opened on one of the inner wall of the sliding groove 1101 and the outer wall of the clamping unit 31, and a limiting block (not shown in the figure) is provided on the other, and the limiting block is inserted into the limiting groove 1102 and is in movable guiding cooperation with the limiting groove 1102. In this way, it can prevent the clamping unit 31 from shifting relative to the sliding groove 1101 during the movement, further improving the reliability of clamping.

[0039] Among them, in this embodiment, the limiting groove 1102 is specifically arranged on the inner wall of the sliding groove 1101, and the limiting block is arranged on the outer wall of the clamping unit 31. To improve the connection strength of the limiting block, the limiting block and the clamping unit 31 can be set as an integral structure.

[0040] Furthermore, the end of the clamping unit 31 close to the bottom plate 12 is preferably in movable abutting cooperation with the bottom plate 12 to further improve the stability of the clamping unit 31 when moving.

[0041] In one embodiment, as Figure 3 and Figure 4As shown, the clamping unit 31 includes a fixing part 311, a clamping part 312, and a pressure sensor 313. The fixing part 311 is installed in the sliding groove 1101. The clamping part 312 is disposed on one side of the fixing part 311 close to the clamping space 301 and is movably connected to the fixing part 311. The clamping part 312 is used to contact and clamp automotive parts. The pressure sensor 313 is disposed between the fixing part 311 and the clamping part 312 and is connected to the fixing part 311 for detecting the pressure received by the clamping part 312. In this way, according to the pressure value detected by the pressure sensor 313, the acting force exerted by the clamping unit 31 on the automotive parts to be assembled can be adjusted, which can avoid deformation and damage of the automotive parts due to excessive clamping force, or shaking of the automotive parts during the assembly process due to too small clamping force, thereby further improving the reliability during clamping.

[0042] Further, in one embodiment, as Figure 5 shown, a fixing hole 3111 is formed in the fixing part 311. The clamping unit 31 further includes an elastic member 314, and the elastic member 314 is installed in the fixing hole 3111. A guiding rod 3121 is connected to the clamping part 312. The guiding rod 3121 is at least partially inserted into the fixing hole 3111 and is connected to the elastic member 314.

[0043] It is easy to understand that when the clamping part 312 clamps the automotive parts, it will receive a corresponding reaction force, causing the guiding rod 3121 to compress the elastic member 314. At this time, the pressure sensor 313 can detect the pressure received by the clamping part 312. When the pressure reaches the specified value, the first driving member 21 will be controlled to achieve self-locking through an electrical signal. After the processing is completed, the self-locking state of the first driving member 21 can be released through a corresponding switch, and the first driving member 21 can be reversed, thereby facilitating the movement and reset of the clamping unit 31.

[0044] In this embodiment, the cross-sections of the fixing part 311 and the clamping part 312 are both rectangular, and the numbers of the fixing hole 3111, the elastic member 314, and the guiding rod 3121 are all set to four, and are respectively disposed at the four corners of the fixing part 311 or the clamping part 312 to improve the stability during movement. Of course, in other embodiments, the numbers of the fixing hole 3111, the elastic member 314, and the guiding rod 3121 can also be adjusted accordingly as needed. For example, the numbers of the fixing hole 3111, the elastic member 314, and the guiding rod 3121 can be set to three and arranged in a triangle, or set to five and arranged in a pentagon, etc., which will not be listed one by one here.

[0045] In one embodiment, as Figure 2 and Figure 4As shown, the positioning and clamping tooling 100 further includes a connecting member 40. Both ends of the adjusting rod 23 are provided with connecting holes (not shown in the figure). The connecting member 40 is passed through and connected to the connecting holes, and is used to movably connect the adjusting rod 23 to the turntable 22 and the clamping unit 31. The adjusting rod 23 can be movably connected to the turntable 22 and the clamping unit 31 through the connecting member 40, which is beneficial to driving the clamping unit 31 to move when the turntable 22 rotates.

[0046] Further, the connecting member 40 of this embodiment includes a connecting portion 41 and a locking portion 42. One end of the connecting portion 41 is connected to the turntable 22 or the clamping unit 31, and the other end passes through the connecting hole and is threadedly connected to the locking portion 42. Among them, after the adjusting rod 23 is sleeved on the connecting portion 41 through the connecting hole, the connecting portion 41 and the locking portion 42 are locked and matched, and the fixed installation of the adjusting rod 23 can be realized. In this way, it is convenient for the disassembly and assembly of the adjusting rod 23, which is beneficial to reducing the assembly difficulty of the adjusting rod 23.

[0047] Optionally, the connecting portion 41 of the connecting member 40 can be welded or integrally formed on the turntable 22 or the clamping unit 31.

[0048] To reduce the friction between the locking portion 42 and the adjusting rod 23, in one embodiment, a plurality of balls (not shown in the figure) can be provided at one end of the locking portion 42 close to the adjusting rod 23, and the locking portion 42 is in abutting cooperation with the adjusting rod 23 through the balls. It can be understood that after the locking portion 42 abuts against the adjusting rod 23 through the balls, the limiting of the adjusting rod 23 in the axial direction of the connecting member 40 can be realized, so that the adjusting rod 23 can only rotate circumferentially along the connecting member 40, improving the movement stability of the adjusting rod 23. At the same time, the balls can also reduce the contact area between the locking portion 42 and the adjusting rod 23, thereby reducing friction, which is beneficial to realizing the rotation of the adjusting rod 23.

[0049] Since the automotive parts in the clamping space 301 will be subjected to external forces during assembly, when these external forces are transmitted to the clamping unit 31, it may cause the clamping unit 31 to move in the direction of the initial position, resulting in a decrease in the clamping stability of the clamping unit 31. Based on this, in order to reduce the probability of the reverse movement of the clamping unit 31 and improve the stability of the clamping unit 31 during clamping, in one embodiment, as Figure 2 shown, the positioning and clamping tooling 100 further includes a limiting mechanism 50. The limiting mechanism 50 is arranged between the main board 11 and the bottom board 12 and is used to prevent the turntable 22 from rotating.

[0050] It can be understood that if the clamping unit 31 is to move in the reverse direction, it will drive the turntable 22 to rotate correspondingly through the adjusting rod 23. And in this embodiment, by setting the limiting mechanism 50, the rotation of the turntable 22 can be prevented, so that the resistance that the clamping unit 31 needs to overcome when moving in the reverse direction increases, thereby improving the clamping stability of the clamping unit 31.

[0051] Further, in one embodiment, as Figure 2 shown, the limiting mechanism 50 includes a second driving member 51 and a limiting plate 52. The second driving member 51 is connected to the main board 11, and the output end of the second driving member 51 is connected to the limiting plate 52. Wherein, the second driving member 51 can drive the limiting plate 52 to move towards the turntable 22 so that the limiting plate 52 abuts against the turntable 22.

[0052] In this way, by the limiting plate 52 abutting against the turntable 22 and applying a force along the axial direction of the turntable 22, the frictional resistance between the limiting plate 52 and the turntable 22 can be greatly increased, thereby effectively preventing the turntable 22 from rotating. Moreover, the force applied to the turntable 22 is relatively uniform, reducing the probability of deformation of the turntable 22.

[0053] Specifically, the second driving member 51 in this embodiment can be a driving cylinder, a driving motor or a telescopic rod and other structures that can play a lifting role. In addition, the first driving member 21 is preferably a driving motor.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0055] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
