[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a precision alignment mechanism for an automotive brake shoe assembly, comprising a base 1, wherein an alignment mechanism 2 is disposed on the base 1 and used for alignment of the brake shoes, the alignment mechanism 2 comprising:
[0025] The main component 21 includes uprights 211 fixed at the four corners of the top of the base 1, a movable plate 212 slidably installed between the four uprights 211, lugs 213 fixed on both sides of the front end of the movable plate 212, a connecting rod 214 pivotally connected to the lugs 213, and a support frame 215 fixed on both sides of the front end of the top of the base 1.
[0026] The protective component 22 includes a bracket 221 pivotally connected to the lower end of the connecting rod 214, and the upper end of the bracket 221 is pivotally connected to the upper end of the upright frame 215. A baffle 222 is provided between the two brackets 221. When the movable plate 212 moves, the movable plate 212 drives the connecting rod 214 through the lug 213. At the same time, with the cooperation of the upright frame 215, the connecting rod 214 drives the protective component 22 to rotate, so that the protective component 22 can provide shielding and protection during the brake shoe alignment process.
[0027] In this embodiment, when the servo cylinder 218 drives the movable plate 212 to move up and down along the upright 211, the lug 213 fixed to the front end of the movable plate 212 drives the connecting rod 214 to move. The connecting rod 214, through pivotal engagement with the upright 215 and the bracket 221, enables the entire protective assembly 22 to complete the flipping action synchronously. This ensures that when the alignment operation begins, the baffle 222 automatically flips to the working position, forming an effective protective barrier. After the operation is completed, the baffle 222 can automatically reset, facilitating the loading and unloading of workpieces. The protective range of the baffle 222 completely covers the working area of the pressure head 2110, reliably blocking metal chips and dust splashed during the alignment process.
[0028] Specifically, the protective component 22 also includes a waist-shaped hole 223 opened inside the bracket 221, and a frame 224 is fixed at both ends of the baffle 222. A bolt head 225 is fixed on the outer wall of the frame 224, and a nut 226 is threaded on the bolt head 225.
[0029] In this embodiment, the baffle 222 can be removed from the bracket 221 simply by loosening the nut 226, which facilitates maintenance and replacement or allows for the replacement of different types of baffles 222 according to different operational needs.
[0030] Specifically, the main component 21 also includes a grating 216 installed on the inner wall of the support frame 215.
[0031] In this embodiment, the grating 216 forms an invisible safety barrier through infrared beams. When the operator's hand or other objects accidentally enter the dangerous area of the calibration, the grating 216 can immediately detect the obstruction signal and trigger the equipment to stop urgently, ensuring that the movement of the pressure head 2110 and the moving plate 212 is immediately interrupted.
[0032] Specifically, the main body component 21 also includes a top plate 217 fixed between the tops of the four uprights 211. A servo cylinder 218 is installed on the top of the top plate 217 and is used to drive the movable plate 212 to rise and fall. A positioning seat 219 is installed in the middle of the top of the base 1, and a pressure head 2110 is installed in the middle of the bottom of the movable plate 212.
[0033] In this embodiment, the servo cylinder 218 provides precise power output for the lifting and lowering movement of the movable plate 212, ensuring that the shaping force applied by the pressure head 2110 to the brake shoes is uniform and controllable. The positioning seat 219 located at the top center of the base 1 cooperates with the pressure head 2110 installed at the bottom center of the movable plate 212 to form a precise shaping working area.
[0034] Specifically, the baffle 222 is made of transparent acrylic sheet.
[0035] In this embodiment, the baffle 222 is made of transparent acrylic sheet material, which has good light transmittance and impact resistance. The baffle 222 made of transparent acrylic sheet can provide the operator with a clear view while achieving effective protection, making it easy to observe the calibration process of the brake shoe inside the calibration mechanism 2 and the working status of the pressure head 2110 in real time.
[0036] Specifically, the base 1 has adjustable shock-absorbing feet at the four corners of its bottom.
[0037] In this embodiment, the shock-absorbing rubber pad is used to absorb the vibration and impact generated during the shaping process.
[0038] The working principle and usage process of this utility model are as follows: First, the servo cylinder 218 provides precise power output for the lifting and lowering movement of the movable plate 212, ensuring that the shaping force applied by the pressure head 2110 to the brake shoes is uniform and controllable. The positioning seat 219 set in the middle of the top of the base 1 and the pressure head 2110 installed in the middle of the bottom of the movable plate 212 cooperate with each other to form a precise shaping working area;
[0039] When the servo cylinder 218 drives the movable plate 212 to move up and down along the upright 211, the lug 213 fixed to the front end of the movable plate 212 drives the connecting rod 214 to move. The connecting rod 214, through pivotal engagement with the upright 215 and the bracket 221, enables the entire protective assembly 22 to complete the flipping action synchronously. This ensures that when the alignment operation begins, the baffle 222 automatically flips to the working position, forming an effective protective barrier. After the operation is completed, the baffle 222 can automatically reset, facilitating the loading and unloading of workpieces. The protective range of the baffle 222 completely covers the working area of the pressure head 2110, reliably blocking metal chips and dust splashed during the alignment process.
