Description

An automated processing equipment and processing technology for brake pump bodies Technical Field

[0001] This invention relates to the field of brake pump body processing technology, and in particular to an automatic processing equipment for brake pump bodies and its processing technology. Background Technology

[0002] Currently, the production of brake pump bodies involves multiple processing steps from raw material to finished product. Traditional production methods rely heavily on manual operation, requiring the transfer of workpieces between various types of equipment, including CNC machining centers, CNC lathes, and specialized machine tools. This process necessitates multiple manual transfers and clamping operations, resulting in high labor costs, low processing efficiency, and increased susceptibility to operational errors due to the numerous manual interventions. These errors can negatively impact product accuracy and quality stability, and also pose certain safety hazards.

[0003] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic processing equipment and processing technology for brake lower pump body, which addresses the shortcomings of the prior art and solves the problems of high labor cost, low processing efficiency, easy impact on product quality, and safety hazards in the processing of brake lower pump body.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic processing equipment for brake pump bodies and its processing technology, comprising a feeding mechanism, a first processing center, a second processing center, an unloading mechanism, and a transition flipping mechanism disposed between the first processing center and the second processing center. The transition flipping mechanism is used to flip the workpiece to be processed and transfer it from the first processing center to the second processing center. A first transfer mechanism is provided on one side of the first processing center, which can sequentially transfer the workpiece to be processed at the feeding mechanism to the first processing center and the transition flipping mechanism. A second transfer mechanism is provided on one side of the second processing center, which can sequentially transfer the workpiece to be processed at the transition flipping mechanism to the second processing center and the unloading mechanism. Both the first processing center and the second processing center are provided with waste removal mechanisms below the processing area.

[0006] By employing the above technical solution, multiple specialized mechanisms are set up and operate in coordination to replace manual labor in a series of operations, including workpiece loading, processing, transfer, flipping, and unloading. The loading mechanism provides the placed workpieces for processing. The first transfer mechanism precisely transfers the workpiece from its initial position to the first processing center for the first processing step, and then transfers it to the transition flipping mechanism. The transition flipping mechanism uses a specific mechanical structure to flip the workpiece, changing its orientation so that the second processing center can perform subsequent processing steps on different surfaces. The second transfer mechanism then transfers the flipped workpiece to the second processing center to complete the remaining processes, and finally transfers it to the unloading mechanism to complete the processing flow. This automated process greatly reduces manual intervention, lowering labor costs; continuous and precise operation improves processing efficiency; reduces human error, thus improving product quality; and simultaneously reduces direct manual operation, lowering safety hazards.

[0007] A further configuration of the above technical solution is as follows: the transition flipping mechanism includes a transition frame, a rodless cylinder mounted on the transition frame, and a slide cylinder mounted on the slider of the rodless cylinder. A fixed plate is mounted on the slider of the slide cylinder, a rotary cylinder is mounted on the side of the fixed plate, a support plate is mounted on the movable end of the rotary cylinder, a transition block capable of limiting the workpiece to be processed is mounted on the support plate, and a rotary clamping cylinder is mounted on the end of the support plate away from the rotary cylinder.

[0008] Using the above technical solution, after the first transfer mechanism transfers the workpiece to be processed from the first machining center to the transition block, the rotary clamping cylinder is activated and works with the transition block to clamp the workpiece. The rotary cylinder then drives the support plate and the workpiece to rotate 90°. Then, the rodless cylinder drives its components and the workpiece to move together to one end closer to the second machining center. After the second transfer mechanism picks up the workpiece, the slide cylinder can drive the rotary cylinder, the support plate and the transition block away from the workpiece. At the same time, the moving end of the rotary clamping cylinder also moves away from the workpiece, thereby releasing the clamping and fixing, so that the second transfer mechanism can take away the workpiece.

[0009] The above technical solution is further configured as follows: the first transfer mechanism includes a first gantry manipulator and a first gripper mounted on the manipulator arm of the first gantry manipulator. The X-axis guide rail of the first gantry manipulator is mounted on the top of the first machining center, and its two ends can extend to the top of the loading mechanism and the transition flipping mechanism, respectively. The Z-axis guide rail of the first gantry manipulator can drive the first gripper to rise and fall and place or pick up the workpiece to be processed from the top of the loading mechanism, the first machining center and the transition flipping mechanism, respectively. The second transfer mechanism includes a second gantry manipulator and a second gripper mounted on the manipulator arm of the second gantry manipulator. The X-axis guide rail of the second gantry manipulator is mounted on the top of the second machining center, and its two ends can extend to the top of the transition flipping mechanism and the unloading mechanism, respectively. The Z-axis guide rail of the second gantry manipulator can drive the second gripper to rise and fall and place or pick up the workpiece to be processed from the top of the transition flipping mechanism, the second machining center and the unloading mechanism, respectively.

[0010] Using the above technical solution, the X-axis guide rail of the first gantry robot determines its horizontal range of motion, enabling it to traverse the loading mechanism, the first machining center, and the transition flipping mechanism, thus realizing the horizontal movement of the workpiece to be processed between different positions. The Z-axis guide rail provides the first gripper with vertical movement capability, allowing it to rise or fall, thereby accurately grasping or placing workpieces from different positions above. Similarly, the working principle of the second gantry robot is the same and will not be elaborated further. This combination of two-dimensional motion allows the first gantry robot to flexibly and accurately transfer workpieces to designated positions, ensuring the orderly progress of the processing flow, improving transfer efficiency and positioning accuracy, and reducing positional deviations that may occur due to manual transfer.

[0011] A further configuration of the above technical solution is as follows: The first machining center includes a first machining table for performing a first machining operation on the workpiece to be machined. An XY slide assembly is mounted on the first machining table. A fixture for fixing the workpiece to be machined is provided on the slider of the Y-axis slide of the XY slide assembly. A tool magazine is mounted on the first machining table above the XY slide assembly. Several tool assemblies are arranged and mounted on the tool magazine along the sliding direction of the X-axis slide of the XY slide assembly. Each tool assembly can drive the tools on it to rise and fall. The second machining center includes a second machining table for performing a second machining operation on the workpiece to be machined. The structure of the second machining table is the same as that of the first machining table. The fixture and the tools in the tool magazine are appropriately adapted and installed according to the requirements of the second machining operation. The second machining center also includes a third machining table for performing a third machining operation on the workpiece to be machined. The structure of the third machining table is the same as that of the first machining table. The fixture and the tools in the tool magazine are appropriately adapted and installed according to the requirements of the third machining operation.

[0012] By employing the above technical solution, the XY slide assembly can move precisely in the X and Y axes, enabling the workpiece fixed on the fixture to accurately reach the designated machining position below the tool, achieving precise control of the machining position. The fixture firmly fixes the workpiece to be machined, ensuring its stability during machining and preventing a decrease in machining accuracy due to workpiece movement. The tool magazine arranges multiple tool assemblies along the X-axis slide direction. Each tool assembly can be independently controlled for tool lifting and lowering. According to machining requirements, different tool assemblies descend sequentially, allowing the corresponding tools to perform different machining operations on the workpiece. This enables diversified machining tasks in the current process, improving machining flexibility and accuracy, and meeting the complex machining requirements of the brake pump body.

[0013] The above technical solution is further configured as follows: two identical first processing tables are provided on the first processing center, which can process the first process on both lines at the same time; a reduction motor is installed on the robotic arm of the first gantry robot and the robotic arm of the second gantry robot; the first gripper and the second gripper are both installed on the output shaft of the corresponding reduction motor and are both arranged in a staggered distribution forming an included angle; the reduction motor can drive the two first grippers or the two second grippers to reciprocate alternately downward.

[0014] By adopting the above technical solution, the first machining center is equipped with two identical first machining tables, realizing parallel processing of the first process. Compared with a single machining table, this greatly improves processing efficiency, enabling the processing of more workpieces in a shorter time. For situations where the processing time of the first process is relatively long, it can improve the efficiency of the entire processing flow. The design of the geared motor driving the gripper allows the gripper to rotate alternately, pointing both grippers downwards. When transferring workpieces, one gripper can be used to grab the workpiece first, and then the geared motor rotates to move the other gripper to a suitable position for the next grab or place operation, realizing the transfer of two workpieces at once. This not only increases the working flexibility of the grippers but also improves the transfer efficiency, reduces waiting time, optimizes the rhythm of the entire processing flow, and further improves the overall processing efficiency of the equipment.

[0015] A further configuration of the above technical solution is as follows: the feeding mechanism includes a feeding frame, a feeding slide mounted on the feeding frame, and a feeding tray assembly mounted on the slider of the feeding slide. The feeding tray assembly includes a feeding plate whose bottom is fixedly connected to the slider of the feeding slide, two sets of linear slide rails arranged inside and outside the feeding plate, and a sliding plate mounted on the slider of the linear slide rail. The sliding plate is provided with a tray, and the two sliding plates are arranged alternately up and down to facilitate manual placement of the workpiece to be processed onto the tray.

[0016] Using the above technical solution, the feeding slide can drive the feeding tray assembly to move horizontally, facilitating the first transfer mechanism to grab the workpiece to be processed. In the feeding tray assembly, two sets of linear slide rails allow the slide plate to slide flexibly horizontally. The two slide plates are alternately set up and down, making it convenient for operators to operate the feeding (placing the workpiece to be processed into the tray) on the side away from the first machining center, ensuring the safety of the operators. At the same time, the CNC system can control the feeding slide to drive the feeding tray assembly to move horizontally, adjusting the position of the tray to cooperate with the first transfer mechanism to grab the workpiece to be processed. Thus, manual feeding and transfer work can be carried out simultaneously, improving the efficiency and safety of feeding.

[0017] A further provision of the above technical solution is that the feeding mechanism includes a feeding frame, a feeding slide mounted on the feeding frame, and a feeding plate mounted on the slider of the feeding slide, wherein a material frame is provided on the feeding plate.

[0018] Using the above technical solution, the unloading slide can drive the unloading plate to move horizontally, facilitating the reception of processed workpieces transferred from the second transfer mechanism. The material frame on the unloading plate is used to collect and store the processed workpieces, ensuring an orderly unloading process and preventing damage caused by random stacking of workpieces. It also facilitates the subsequent sorting and handling of finished products, ensuring the integrity and efficiency of the entire processing flow.

[0019] A further configuration of the above technical solution is as follows: the waste discharge mechanism includes a base and a water tank disposed on one side of the base. The upper end of the base is provided with a waste discharge trough. The bottom of the waste discharge trough is an inclined surface with one end near the bottom of the water tank and the other end higher. The base extends outward from the side near the water tank and is provided with a waste discharge port communicating with the waste discharge trough. The upper end of the water tank is provided with a filter screen with a fence, and the end of the waste discharge port is located above the filter screen. The second processing center is provided with a chip removal device located below the second gantry robot arm at the end near the unloading mechanism. The second gantry robot arm can grab the workpiece to be processed and extend it into the chip removal device to complete the cleaning operation of the waste chips on the surface of the workpiece.

[0020] By adopting the above technical solution, the waste discharge trough with inclined surface can realize the automatic flow of cutting fluid and chips, and the solid-liquid separation can be realized with the help of filter screen. This facilitates the centralized cleaning of chips and the recycling and reuse of cutting fluid, while avoiding the accumulation of processing chips that may affect the normal operation of the equipment and ensuring the cleanliness of the processing environment. After processing is completed and before unloading, the chip removal device automatically cleans the processing chips on the surface of the workpiece, eliminating the need for additional manual cleaning and further improving the fully automated operation. At the same time, it prevents chips from entering the unloading stage with the workpiece, ensuring the cleanliness of the finished product.

[0021] A processing technology for an automatic processing equipment for brake pump bodies includes the following steps: S1: The workpiece to be processed is manually placed on the tray of the loading mechanism, and the tray carrying the workpiece is moved to the gripping station of the first transfer mechanism via the loading slide; S2: The first gripper of the first transfer mechanism grips the workpiece to be processed from the tray of the loading mechanism, transfers it, and places it on the fixture of the first machining center for fixation, and then the first machining center begins to process the workpiece; S3: When the first machining center completes the processing of the workpiece, the first gripper of the first transfer mechanism grips the workpiece from the fixture of the first machining center and transfers it to the transition block of the transition flipping mechanism; S4: The workpiece is clamped and fixed by the rotary clamping cylinder of the transition flipping mechanism, and then flipped by the rotary cylinder, followed by the rodless... The cylinder moves the workpiece towards the second machining center, eventually transferring the workpiece to the area below the second transfer mechanism; S5: The second gripper of the second transfer mechanism moves above the transition flipping mechanism and lowers to clamp the workpiece. The rotary clamping cylinder and slide cylinder of the transition flipping mechanism are activated to release the clamping and fixing of the workpiece. The second gripper of the second transfer mechanism picks up the workpiece and places it on the fixture of the second machining center for fixing. Then, the second machining center begins to reprocess the workpiece; S6: When the second machining center completes the processing of the workpiece, the second gripper of the second transfer mechanism picks up the workpiece from the fixture of the second machining center and transfers it into the chip removal device for chip cleaning; S7: After the chip cleaning is completed, the second gripper of the second transfer mechanism picks up the workpiece and places it into the material frame of the unloading mechanism.

[0022] In step S2, the first machining center is equipped with two identical first machining tables, which simultaneously process the first process on two lines to improve the overall processing efficiency. In step S5, the second machining center includes a second machining table for processing the second process and a third machining table for processing the third process. The fixtures installed on the second and third machining tables, together with the XY slide assembly, form a four-axis or five-axis fixture to support multi-directional processing of the workpiece.

[0023] The beneficial effects achieved by this invention are as follows: By integrating a feeding mechanism, a transfer mechanism, a multi-process machining center, a transition and flipping mechanism between machining centers, a chip removal device, a waste removal mechanism, and a unloading mechanism, the automated operation of the brake lower pump body machining is realized. This eliminates the need for manual transfer and clamping between multiple machines, significantly reducing labor costs and greatly shortening the single workpiece processing cycle. It also avoids clamping errors caused by manual operation, ensuring product processing accuracy and batch consistency, and eliminating safety hazards associated with manual operation. Furthermore, the dual-station machining and dual-jaw transfer design perfectly matches the processing rhythm of multiple processes, avoiding process bottlenecks and significantly improving the overall processing capacity of the equipment.

[0037] As shown in Figure 1, both the first machining center 2 and the second machining center 3 are equipped with control panels and teach pendants, which facilitate operators to debug equipment, set parameters and manage operation.

[0038] All the above tooling is equipped with standard replacement holes, covering components such as robotic grippers, fixtures, and cutting tools, which facilitates quick adjustment when changing products of different shapes on the entire production line, thereby improving the overall utilization rate and versatility of the production line.

[0039] The processing technology of this embodiment includes the following steps: S1: The workpiece to be processed is manually placed on the tray 16 of the loading mechanism 1, and the tray 16 carrying the workpiece is moved to the gripping station of the first transfer mechanism 6 by the loading slide 12; S2: The first gripper 62 of the first transfer mechanism 6 grips the workpiece to be processed from the tray 16 of the loading mechanism 1, transfers it and places it on the fixture 23 of the first machining center 2 for fixation, and then the first machining center 2 drives the machine part to move through the XY slide assembly 22, and performs the first processing operation on the workpiece in conjunction with the tool assembly 25 of the tool magazine 24; The two first processing tables 21 of the machining center 2 perform parallel processing in dual stations, improving the processing efficiency of the first process; S3: When the first machining center 2 completes the processing of the workpiece, the XY slide assembly 22 drives the workpiece back to the loading and unloading station, and the first gripper 62 of the first transfer mechanism 6 picks up the workpiece that has completed the first process from the fixture 23 and transfers it to the transition block 57 of the transition flipping mechanism 5; S4: The rotary clamping cylinder 58 of the transition flipping mechanism 5 is activated to clamp and fix the workpiece on the transition block 57, and the rotary cylinder 55 is activated to drive the workpiece to complete a 90° flip, and then the rodless cylinder 5 2. Start-up: The flipped workpiece moves towards the second machining center 3, eventually transferring it to below the gripping station of the second transfer mechanism 7; S5: The second gripper 72 of the second transfer mechanism 7 moves above the transition flipping mechanism 5 and lowers to grip the workpiece. The rotary clamping cylinder 58 of the transition flipping mechanism 5 releases, and at the same time, the slide cylinder 53 drives the transition block 57 to move away from the workpiece to avoid it. After the second gripper 72 grips the workpiece, it is placed sequentially on the fixtures 23 of the second machining table 31 and the third machining table 32 of the second machining center 3 according to the process flow, completing the second and third processes sequentially. In the processing of the process, the fixtures 23 installed on the second processing table 31 and the third processing table 32, together with the XY slide assembly 22, form a four-axis or five-axis fixture to support multi-directional processing of the workpiece; S6: When the second processing center 3 completes all the processing of the workpiece, the second gripper 72 of the second transfer mechanism 7 picks up the finished workpiece from the fixture 23 and transfers it into the chip removal device 9 for chip cleaning; S7: After the chip cleaning is completed, the second gripper 72 of the second transfer mechanism 7 picks up the workpiece and places it into the material frame 44 of the unloading mechanism 4 to complete the automated processing of a single workpiece.

[0040] The first process described above is mainly used to complete the following machining on the inner surface of the brake pump body: milling the upper plane, milling the T-slot, drilling the connecting hole, milling the mounting surface, chamfering the mounting hole, drilling the stepped hole, drilling the pin hole, and tapping the mounting hole and connecting hole. In the existing technology, the milling of the mounting surface and the chamfering of the mounting hole in this process need to be processed separately using a special machine tool, and the remaining machining needs to be transferred to another CNC machining center, requiring multiple manual clamping operations. The second process is mainly used to complete the rough and fine reaming of the piston hole, broaching the sealing ring groove, broaching the bottom groove, etc. on the inner surface of the brake pump body, and can be adapted to the machining of multi-piston hole products of the same specification. In the existing technology, this process requires one or more CNC lathes for machining, and for multi-piston hole products, multiple manual clamping operations are also required. The third process mainly involves drilling and scraping oil inlet holes, tapping oil inlet holes, drilling and tapping vent holes, drilling small vent holes, drilling and tapping backstitch threads, and drilling oblique holes at multiple angles on the outer or circumferential surface of the brake pump body. In existing technology, this process requires two or more specialized machine tools and multiple manual clamping operations on the workpiece. The actual machining positions and sequence of the above processes can be adjusted according to the specific structure and process requirements of different products.

[0041] This embodiment achieves automated operation of brake pump body processing by integrating a feeding mechanism, a transfer mechanism, a multi-process machining center, a transition and flipping mechanism between machining centers, a chip removal device, a waste removal mechanism, and a unloading mechanism. It eliminates the need for manual transfer and clamping between multiple machines, significantly reducing labor costs and shortening the processing cycle of a single workpiece. It also avoids clamping errors caused by manual operation, ensuring product processing accuracy and batch consistency, and eliminating safety hazards associated with manual operation. The dual-station machining and dual-jaw transfer design perfectly matches the processing rhythm of multiple processes, avoiding process bottlenecks and significantly improving the overall processing capacity of the equipment.
