Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to brake caliper assembly technology. Background Technology

[0002] In the brake caliper assembly process, the assembly of the rectangular ring in the caliper body has been automated. The principle is as follows: the rectangular ring is first placed on the rectangular ring positioning rod, then the positioning rod moves the rectangular ring into the caliper body cylinder bore. The cylinder bore has a rectangular ring mounting slot; once the rectangular ring is engaged in the mounting slot, the rectangular ring positioning cylinder retracts from the caliper body cylinder bore. However, accurately placing the rectangular ring on the positioning rod is quite difficult because the rectangular ring is elastic and can easily separate from the positioning rod during placement.

[0028] Reference Figures 1 to 12 As shown, this embodiment provides a brake caliper body assembly device, including a cylinder bore cleaning and inspection device 4, a rectangular ring automatic assembly device 1, and a caliper body assembly unit 3. The cylinder bore cleaning and inspection device 4 has four stations, sequentially performing caliper body loading, cylinder bore cleaning, visual inspection, and rectangular ring assembly. Corresponding to the cylinder bore cleaning station and the visual inspection station are cylinder bore cleaning components and visual inspection components. The cylinder bore cleaning component includes a high-pressure air gun, and the visual inspection component includes a camera. Therefore, at the cylinder bore cleaning station, the high-pressure air gun is used to clean the inside of the cylinder bore. Then, at the visual inspection station, the camera captures images of the inside of the cylinder bore and performs visual inspection to determine whether the inside of the cylinder bore is completely clean, to avoid incomplete cleaning affecting the rectangular ring assembly. After passing the visual inspection, the rectangular ring is assembled at the rectangular ring assembly station in conjunction with the rectangular ring automatic assembly device 1. The cylinder bore cleaning and inspection device 4 has a first turntable, which, by rotating, can sequentially transport the caliper body 100 to the corresponding stations. The clamp assembly unit 3 is used to assemble the clamp 100 after the rectangular ring is assembled.

[0029] The automatic rectangular ring assembly device 1 includes:

[0030] A rectangular ring material storage 11 is provided, which stores stacked rectangular rings, and the bottom of the rectangular ring material storage 11 is provided with a material discharge port.

[0031] The rectangular ring feeding switching mechanism 12 includes a rectangular ring feeding switching seat 121 with a rectangular ring shifting groove 123 and a translation driver that drives the rectangular ring feeding switching seat to move between the material discharge port and the rectangular ring positioning station.

[0032] A rectangular ring positioning and assembly mechanism is provided below the rectangular ring positioning station. It includes a rectangular ring positioning rod 13 with a rectangular ring positioning groove 131 and a first lifting driver that drives the rectangular ring positioning rod to move up and down. The rectangular ring positioning groove 131 is located at the upper end of the rectangular ring positioning rod 13. The diameter of the lower groove opening of the rectangular ring positioning groove 131 is larger than that of the upper groove opening, thereby forming a limiting flange at the edge of the lower groove opening. The upper end face of the rectangular ring positioning rod 13 is chamfered to facilitate the initial positioning of the rectangular ring at the upper end of the rectangular ring positioning rod 13.

[0033] A rectangular ring pressing mechanism 14 is located above the rectangular ring positioning station. The mechanism includes a pressing block 141 and a second lifting driver that drives the pressing block to move up and down. When the pressing block 141 moves downwards, it presses the rectangular ring onto the rectangular ring positioning rod 13. The pressing block 141 is a cylindrical structure with an opening at the bottom, and its inner diameter is larger than the diameter of the upper end of the rectangular ring positioning rod. Thus, the cylindrical wall of the pressing block presses the rectangular ring downwards from the upper end of the rectangular ring positioning rod 13 until it reaches the height corresponding to the rectangular positioning groove 131.

[0034] A rectangular ring chuck mechanism 15 is located on the side of the rectangular ring positioning station and corresponds to the height of the rectangular ring positioning groove 131. It includes an upper chuck 152 and a lower chuck 151. The lower chuck 151 is used to press the rectangular ring into the rectangular ring positioning groove, and the upper chuck 152 is used to prevent the rectangular ring from coming out of the rectangular ring positioning groove.

[0035] A translation mechanism is provided to drive the rectangular ring positioning and assembly mechanism to switch between the rectangular ring positioning station and the rectangular ring assembly station. When the rectangular ring positioning and assembly mechanism is located at the rectangular ring assembly station, the first lifting driver drives the rectangular ring positioning rod to move the rectangular ring into the clamp cylinder hole.

[0036] The above-mentioned automatic rectangular ring assembly device employs a rectangular ring chuck mechanism, which includes an upper chuck and a lower chuck. The lower chuck is used to press the rectangular ring into the rectangular ring positioning groove, while the upper chuck is used to prevent the rectangular ring from coming out of the rectangular ring positioning groove. Therefore, the rectangular ring can be positioned in the rectangular ring positioning groove and is prevented from coming out.

[0037] In some embodiments, the lower chuck 151 includes two first jaws 1511 located on opposite sides and a two-finger cylinder 153 for driving the opening and closing of the two first jaws 1511. The upper chuck 152 includes two second jaws 1521 located on opposite sides and an elastic element for elastically driving the two second jaws 1521 to close. The rectangular ring loading switch seat 121 transfers the rectangular ring from the discharge port to above the rectangular ring positioning rod 13. When the pressure block 141 moves downward, it presses the rectangular ring onto the rectangular ring positioning rod, aligning it with the position of the rectangular ring positioning groove. Then, the two-finger cylinder 153 drives the two first jaws 1511 to close, squeezing the rectangular ring into the rectangular ring positioning groove. Because the rectangular ring is elastic, the squeezing action of the lower chuck causes the rectangular ring to deform, and the rectangular ring may move upward. However, the elastic element drives the two second jaws 1521 to close, cooperating with the upper groove of the rectangular ring positioning groove 131, which can prevent the rectangular ring from coming off upward.

[0038] Specifically, a positioning shaft 155 is fixed on the lower chuck 151, and a positioning groove 1522 is provided on the upper chuck 152. The positioning shaft 155 cooperates with the positioning groove 1522. The elastic element is a spring 154, which is installed in the positioning groove, with one end connected to the first end of the positioning groove and the other end connected to the positioning shaft. Therefore, the lower chuck can drive the upper chuck to open through the positioning shaft, and when the lower chuck is closed, the positioning shaft and the spring act together to elastically drive the upper chuck to close.

[0039] Furthermore, the lower chuck 151 is provided with a chuck groove 1514, and the upper chuck 152 slides along the chuck groove 1514, thus restricting the relative sliding direction of the upper and lower chucks. A first groove 1512 is provided on the adjacent side of the two first jaws. The first groove is arc-shaped, thus it can engage with the partial arc of the outer circle of the rectangular ring. An extension section 1513 is provided on one side of each of the two first jaws, and the extension section of one first jaw engages with the side of the other first jaw for limiting engagement. A second groove 1521 is provided on the adjacent side of the two second jaws. The second groove is arc-shaped, thus it can engage with the partial arc of the outer circle of the rectangular ring.

[0040] Additionally, the rectangular ring automatic assembly device 1 is equipped with a mounting frame 16, which includes an upper mounting plate 161 and a lower mounting plate 163. The upper mounting plate is provided with a switching groove 162, along which the rectangular ring feeding switching seat 121 moves. The lower mounting plate 163 is provided with a mounting groove 164 for mounting the upper chuck 152 and the lower chuck 151. A two-finger cylinder 153 is located on the side of the lower mounting plate 163, and the lower chuck 151 extends out from the mounting groove 164 and connects to the two-finger cylinder 153. The mounting frame 16 is provided with a positioning hole 165, in which the pressure block 141 and the upper part of the positioning rod can engage, while the two first claws and two second claws can extend into the positioning hole and engage with the positioning rod 13.

[0041] In some embodiments, the rectangular ring material storage 11 has an observation slot 111 on its side wall, and a material dropping counterweight 112 is provided above the rectangular ring material storage 11, which is pressed against the stacked rectangular rings. The bottom of the rectangular ring material storage 11 has a base 113, which is fixed to the upper mounting plate 161 and located above the switching slide 162. The material dropping port is located on the base 113. In the rectangular ring feeding and switching mechanism 12, the translation actuator is a translation cylinder 122, and the rectangular ring feeding and switching seat 121 has an L-shaped structure, including a vertical section and a horizontal section. The cylinder push rod of the translation cylinder 122 is connected to the vertical section, and the rectangular ring shifting slot 123 is located on the horizontal section. The horizontal section is relatively long; when the rectangular ring shifting slot 123 moves to the rectangular ring positioning station, part of it is still below the material dropping port, so the rectangular ring cannot fall. Only when the rectangular ring shifting slot 123 is directly opposite the material dropping port can the rectangular ring fall into the rectangular ring shifting slot 123.

[0042] In some embodiments, the second lifting actuator is a lifting cylinder 142, which is installed above the crossbeam of the gantry bracket 143, and the two side frames of the gantry bracket 143 are correspondingly fixed to the two sides of the upper mounting plate 161.

[0043] In some embodiments, the clamp assembly unit 3 includes a second turntable. The second turntable drives the clamp to rotate, moving the clamp to the piston assembly station, low-pressure sealing test station, high-pressure sealing test station, and vacuum sealing test station, respectively, to perform piston assembly, low-pressure sealing test, high-pressure sealing test, and vacuum sealing test. It is understood that, depending on the type of caliper, additional stations may be added. Taking a previous caliper as an example, a total of six stations are set: clamp loading (dust cover press-fit) → piston press-fit → piston sliding resistance test → low-pressure sealing test → high-pressure sealing test → vacuum sealing test. Specific assembly processes can refer to existing technologies.

[0044] The caliper assembly unit includes a piston assembly station where the piston is press-fitted into the caliper cylinder bore. To achieve automatic piston feeding, the brake caliper assembly equipment also includes an automatic piston feeding device. In existing technologies, pistons come from various sources and may have dimensional errors. If a piston with incorrect dimensions is assembled into the caliper, subsequent quality inspection can easily result in a defective brake caliper. Reassembling the piston, however, wastes time and effort, impacting assembly efficiency.

[0045] like Figures 9 to 12 As shown, to avoid assembling defective pistons, in this embodiment, the automatic piston feeding device 2 includes a weighing component 21, an automatic piston feeding robot, and a defective material frame 26. The weighing component 21 is used to weigh the pistons, and the automatic piston feeding robot is used to place the pistons on the weighing component and feed pistons that meet the weighing requirements, while placing pistons that do not meet the weighing requirements into the defective material frame. This ensures the consistency of the incoming piston dimensions and avoids assembling defective pistons.

[0046] Specifically, the automatic piston feeding robot includes a piston transfer gripper 22 and a gripper moving mechanism that drives the piston transfer gripper to rotate horizontally, move vertically, and translate horizontally. The gripper moving mechanism needs to realize the horizontal rotation, vertical movement, and translation of the piston transfer gripper, so that the piston transfer gripper can perform related actions such as placing the piston on the weighing component, feeding pistons that have passed the weighing test, and placing pistons that have failed the weighing test into the defective material frame.

[0047] The piston transfer gripper 22 is provided in two parts. The gripper moving mechanism includes a gripper rotary cylinder 23 and a rotating component 231 driven by the gripper rotary cylinder. The two piston transfer grippers 22 are mounted on the rotating component and are arranged on opposite sides of the rotation center of the rotating component. In this way, the two piston transfer grippers 22 can operate independently. For example, one piston transfer gripper 22 picks up a piston, while the other piston transfer gripper 22 places the piston on the weighing component for weighing. Or, one piston transfer gripper 22 places a piston on the weighing component for weighing, while the other piston transfer gripper 22 places a piston that fails to meet the weight requirement into the defective material frame. Or, one piston transfer gripper 22 places a piston on the weighing component for weighing, while the other piston transfer gripper 22 feeds a piston that meets the weight requirement.

[0048] Furthermore, the gripper moving mechanism also includes a gripper lifting cylinder 24 disposed above the gripper rotating cylinder 23. The cylinder rod of the gripper lifting cylinder is connected to a lifting block 241, and the lifting block 241 is connected to the gripper rotating cylinder. The gripper moving mechanism also includes a lead screw and nut assembly 25, which includes a lead screw 251, a translation slider 252 threadedly connected to the lead screw, and a horizontal guide rail 253 cooperating with the translation slider. The gripper lifting cylinder is connected to the translation slider.

[0049] In some embodiments, the piston-transfer gripper 22 has at least three fingers 221 evenly distributed circumferentially. These three fingers are driven by finger cylinders to move radially to separate and close the gripper. Because the piston has a regular cylindrical structure, the radial movement of multiple fingers 221 facilitates the separation and closure of the gripper, making it convenient to grasp and release the piston.

[0050] In some embodiments, the weighing component 21 includes a weighing tray 211 for supporting the piston and a weighing sensor 212 disposed below the weighing tray. The weighing component also includes a weighing bracket 214, which has a support platform 2141 with a through hole 2142. The piston is placed above the through hole, and the weighing tray is positioned below the through hole before weighing. The weighing sensor is connected to a weighing lifting cylinder 213. During weighing, the weighing lifting cylinder raises the weighing sensor, causing the weighing tray to pass upwards through the through hole and lifting the piston for weighing. Without this weighing lifting cylinder, if the piston transfer gripper cannot properly control the piston's position on the weighing tray, the weighing sensor may be damaged (overload).

[0051] Furthermore, the upper end of the through hole is provided with a piston positioning groove 2143 for positioning the piston, thus preventing the piston from deviating too much from the center of the through hole and ensuring that the piston roughly corresponds to the center of the weighing tray. The through hole is a stepped hole, and the diameter of the piston positioning groove is larger than the diameter of the through hole body below. The piston cannot fall through the through hole body below the piston positioning groove, but the weighing tray can pass upward through the through hole.

[0052] In addition, the defective material box 26 is arranged adjacent to the weighing component 21. This facilitates one piston transfer gripper 22 to place the piston onto the weighing component for weighing, and the other piston transfer gripper 22 to place the piston that fails to meet the weight requirement into the defective material box.

[0053] It is understandable that the cylinder used in the aforementioned automatic piston feeding device 2 can be purchased directly from the market. Moreover, the cylinder can also be replaced by a component with similar functionality, such as an electric cylinder.

[0054] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art should understand that the invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the invention will be included within the scope of the claims.
