Description

Technical Field

[0002] A conventional suspension for a vehicle comprises a leaf spring made of one or more superimposed leaf springs, which is arranged longitudinally adjacent to and below a frame rail of the vehicle. A front leaf spring bracket and a rear leaf spring bracket are provided, both of which are fixed to the vehicle frame. The front end of the leaf spring is engaged in the front leaf spring bracket, usually without freedom in the longitudinal direction, while the rear end of the leaf spring is engaged in the rear leaf spring bracket so as to be able to slide longitudinally relative to the first leaf spring bracket.

[0003] For example, Chinese patent publication number CN118559330A discloses a leaf spring bracket welding fixture, including a base plate, a drive unit and a clamping mechanism. The above application uses the clamping group 1 in the clamping mechanism to align the left and right end faces of the two U-shaped metal horizontal plates, and makes the two U-shaped metal horizontal plates parallel to each other, and then the clamping group 2 completes the center clamping of the metal vertical plates placed on the two U-shaped metal horizontal plates in the front-to-back direction and the left-to-right direction, so that the metal vertical plates are in the middle area of ​​the upper end faces of the two U-shaped metal horizontal plates, avoiding the reduction of the bearing capacity of the leaf spring bracket after welding due to the deviation of the position of the metal vertical plates, and then the staff uses welding equipment to weld the connection between the metal horizontal plate and the metal vertical plate and the connection between the metal vertical plate and the arc-shaped metal plate in sequence, avoiding cumbersome operation steps and easy operation.

[0024] The clamping mechanism 6 further includes a support 68 fixed on the second mounting plate 62, on which an adjustment plate 66 is rotatably mounted via a pivot 69, the pivot 69 being disposed in the middle of the adjustment plate 66, and the adjustment plate 66 can rotate around the pivot 69. The upper end of the adjustment plate 66 is fixedly connected to the clamping block 65, and the lower end of the adjustment plate 66 is movably connected to a piston rod of a push cylinder 67, which is fixed to the first mounting plate 61.

[0025] The drilling assembly 5 is fixed on the lifting plate 43. The drilling assembly 5 includes a driving mechanism 51, a third mounting frame 52 and a drilling mechanism 53 which are sequentially connected from top to bottom. The drilling mechanism 53 includes N drill bits 533. The driving mechanism 51 is used to drive the drill bits 533 to rotate.

[0026] The driving mechanism 51 includes a second mounting frame 511, a motor 512 is fixedly mounted on the upper end of the second mounting frame 511, a first synchronous pulley 513 and a second synchronous pulley 514 are rotatably mounted in the second mounting frame 511, the first synchronous pulley 513 and the second synchronous pulley 514 are connected by a synchronous belt, the first synchronous pulley 513 is fixedly connected to the motor 512, the second synchronous pulley 514 is fixedly connected to the rotating shaft 515, and the rotating shaft 515 is mounted in the third mounting frame 52 through a bearing 516.

[0027] The drilling mechanism 53 includes a fourth mounting frame 531. One end of the rotating shaft 515 extends out of the fourth mounting frame 531 and is connected to a chuck 532. The chuck 532 is used to install the drill bit 533. A driving gear 534 is also fixedly mounted on the rotating shaft 515. The driving gear 534 and the gear set 535 are also provided with a chuck 532 on the output end of the gear set 535.

[0028] Working principle: 1. Preparation The leaf spring brackets 7 to be processed are placed on the clamping mechanism 6 in a rectangular array. Figure 1-Figure 3 As shown, in this embodiment, N=3, that is, the clamping mechanism 6 clamps and fixes 3 leaf spring brackets 7 along the Y-axis direction and clamps and fixes 2 leaf spring brackets 7 along the X-axis direction, and can fix 2*3=6 leaf spring brackets 7 at the same time; 3 drill bits 533 are provided; 3 first positioning plates 63, 3 clamping blocks 65 and 4 second positioning plates 64 are provided on the second mounting plate 62.

[0029] Since the distance between two adjacent second positioning plates 64 is equal to the length of the leaf spring bracket 7, the two wide sides of the leaf spring bracket 7 are respectively in contact with the inner walls of the two second positioning plates 64, thereby ensuring that the leaf spring bracket 7 can be accurately positioned in the length direction when inserted. The first positioning plate 63 is in contact with one long side of the leaf spring bracket 7, further determining the position of the leaf spring bracket 7 in one direction.

[0030] When the leaf spring bracket 7 is placed between the first positioning plate 63 and the second positioning plate 64, the push cylinder 67 is started. The piston rod of the push cylinder 67 extends out to push the lower end of the adjustment plate 66. Since the adjustment plate 66 rotates around the pivot 69, when the lower end is pushed, the upper end will drive the clamping block 65 to move toward the leaf spring bracket 7. The clamping block 65 is attached to the other long side of the leaf spring bracket 7, and works together with the first positioning plate 63 and the second positioning plate 64 to firmly clamp and fix the leaf spring bracket 7 in the middle to ensure that it will not move during the processing.

[0031] 2. Position adjustment stage By controlling the X-axis linear module 2 to move in the horizontal X-axis direction, the drilling assembly 5 is roughly moved to a suitable position above the leaf spring bracket 7. After the X-axis linear module 2 is moved into position, the Y-axis linear module 3 is started to further accurately adjust the position of the drilling assembly 5 in the horizontal Y-axis direction so that it is aligned with the leaf spring bracket 7 in the Y-axis direction.

[0032] Next, the lifting cylinder 42 of the lifting mechanism 4 is started. The piston rod of the lifting cylinder 42 extends, driving the lifting plate 43 to move downward along the guide rail 45. The slider 44 slides smoothly on the guide rail 45 to ensure that the movement direction of the lifting plate 43 is accurate and stable. The lifting plate 43 drives the drilling assembly 5 and other components installed thereon to move downward together, so as to adjust the height of the drilling assembly 5, so that the drill bit 533 is close to the leaf spring bracket 7 but not in contact with it, and is ready for the drilling operation.

[0033] 3. Drilling stage When the drilling assembly 5 is adjusted to the correct position, the drilling assembly 5 is started. Since three drill bits are arranged on the output end of the drilling assembly 5 along the Y-axis direction, and the distance between two adjacent drill bits is the same as the distance between two adjacent leaf spring brackets, the three leaf spring brackets 7 can be drilled at the same time.

[0034] The motor 512 in the driving mechanism 51 is started to drive the first synchronous pulley 513 to rotate. The first synchronous pulley 513 drives the second synchronous pulley 514 to rotate through the synchronous belt. The second synchronous pulley 514 is fixedly connected to the rotating shaft 515, thereby driving the rotating shaft 515 to rotate. The rotating shaft 515 is installed in the third mounting frame 52 through a bearing to ensure that the rotating shaft 515 can rotate stably. One end of the rotating shaft 515 extends out of the fourth mounting frame 531 and is connected to a chuck 532. As the rotating shaft 515 rotates, the drill bit 533 is driven to rotate. The driving gear 534 fixedly installed on the rotating shaft 515 also rotates accordingly, and the driving gear 534 meshes with the gear set 535 to transmit power to the gear set 535. The gear set 535 further transmits power to the chuck 532 on its output end, so that the drill bit 533 installed on the chuck 532 also starts to rotate. Due to the function of the gear set 535, multiple drill bits 533 can rotate simultaneously, meeting the demand for drilling multiple leaf spring brackets 7 at the same time.

[0035] When the drill bit 533 rotates, the height of the drilling assembly 5 is adjusted by the lifting mechanism 4 so that the drill bit 533 gradually approaches the leaf spring bracket. After the drill bit 533 contacts the leaf spring bracket 7, the drilling operation begins. Since the three drill bits rotate at the same time and their positions correspond to the leaf spring bracket 7, multiple leaf spring brackets 7 can be drilled efficiently and accurately at the same time. After the drilling is completed, the drilling assembly 5 is lifted up by the lifting mechanism 4 and away from the leaf spring bracket 7.

[0036] Then start the X-axis linear module 2 to drive the drilling assembly 5 to move along the X-axis direction to drill holes in the next row of leaf spring brackets 7, and repeat the above steps to perform the next round of processing.

[0037] After the drilling is completed, the clamping mechanism 6 is released and the processed leaf spring bracket 7 is taken out.

[0038] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
