Description

Technical Field

[0001] This invention relates to the field of product processing. More specifically, this invention relates to a processing mold for parking ratchet used in automobiles and a detection system for parking ratchet. Background Technology

[0002] Automatic transmission vehicles generally include three braking systems: service brake system, parking brake system, and auxiliary braking system. The service brake system applies short-term braking during vehicle movement to bring the vehicle to a stop or decelerate. The parking brake system stabilizes the vehicle after it has come to a stop, preventing it from rolling away and causing accidents when parked on a slope. The parking brake system typically consists of three parts: a shifting mechanism, a self-locking mechanism, and a locking mechanism. The locking mechanism usually consists of a parking ratchet and a parking pawl. Therefore, the parking ratchet plays a significant role in enabling the vehicle to park.

[0003] In the current technology, the mainstream machining method for the ratchet tooth groove of the parking ratchet is to use CNC milling machines to ensure its machining accuracy. However, for a parking ratchet with 6 ratchet tooth grooves, after the blank is fixed, it takes at least 5 minutes to machine 6 ratchet tooth grooves on the existing CNC milling machine. The machining speed is too slow, which affects the output of parking ratchet manufacturers. Summary of the Invention

[0042] In step two, the detection fixture is configured to include a cooperating movable mold and a fixed mold.

[0043] The lower end face of the fixed mold is connected to the telescopic mechanism. The upper end face of the fixed mold is provided with a hollow shaft that can extend into the center hole of the parking ratchet. The free end of the hollow shaft is provided with a cap for fixing the blank material by means of a thread. The hollow shaft is also provided with a first boss for raising the spatial position of the parking ratchet.

[0044] The movable mold has a through hole at its center for the parking ratchet to pass through. Around the through hole are a number of second fixing components that mate with the ratchet teeth. Each fixing component has a corresponding sensor on its free end that mates with the parking ratchet.

[0051] S22, the first control terminal starts the motor, performs step-by-step adjustment of the angle of the movable module, and counts the number of adjustments. After the movable module completes the angle adjustment, it returns to S20.

At this point, the first control terminal issues a prompt indicating that the detection is complete.

[0053] The testing platform is provided with a positioning shaft that can extend into the center hole of the parking ratchet. The positioning shaft is provided with matching marking points, and the positioning shaft is provided with a second protrusion that raises the spatial position of the parking ratchet.

[0054] An image acquisition mechanism is positioned above the detection platform and spatially aligned with the center of the positioning axis;

[0055] A robotic arm is installed on one side of the testing table to place the parking ratchet to be tested on the positioning shaft or to flip the parking ratchet for testing.

[0056] A labeling machine installed on one side of the testing table to add labels to defective parking ratchet wheels;

[0057] A second control terminal is set on one side of the detection table and communicates with the image acquisition mechanism, the robotic arm, and the labeling machine.

[0058] Preferably, the testing process of the intelligent testing production line is configured to include:

[0065] Secondly, the present invention performs secondary inspection on the processed parking ratchet to ensure that the processing accuracy of the parking ratchet meets the usage requirements.

[0066] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0087] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0088] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0089] It should be noted that in the description of this invention, the orientations or positional relationships indicated by terms are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0090] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0091] Figure 1-4 14 illustrates an implementation of a machining mold for a parking ratchet according to the present invention, comprising:

[0092] The lower mold assembly 1 is provided with a fixed shaft 110 that mates with the center hole of the blank 4;

[0093] The upper mold assembly 2 is provided with multiple sets of stamping cutters 210 that process the edges of the blank to obtain ratchet tooth grooves;

[0094] Multiple sets of telescopic guide components 3 that connect the upper mold assembly and the lower mold assembly into one unit;

[0095] The lower die assembly is provided with multiple clearance areas 120 that cooperate with the external structure of the stamping tool. Each clearance area corresponds to the location of each stamping tool in space, and the depth of each clearance area is matched with the downward depth of each stamping tool. This design allows the stamping tool to penetrate into the lower die during the stamping process to ensure that it can penetrate the blank material. At the same time, the clearance areas can also store the scrap material generated during stamping.

[0096] The working principle is as follows: First, the blank material is inserted into the fixed shaft of the lower die assembly. Since the upper die assembly is in direct contact with the hydraulic equipment, the force applied by the hydraulic equipment causes the upper die assembly to drive the stamping cutter downward. During the downward movement of the stamping cutter, the blank material set on the fixed shaft is stamped. The stamping (or cutting) of the stamping cutter produces ratchet tooth grooves. Since the number of teeth of the stamping cutter in space is the same as the number of teeth of the ratchet tooth groove, multiple corresponding ratchet tooth grooves can be obtained in one stamping, thus completing the processing of the parking ratchet. Processing a parking ratchet only takes about 10 seconds, which effectively improves production efficiency compared to the existing methods.

[0097] In another example, the upper end face of the lower mold assembly is rotatably provided with multiple sets of first fixing components 130 that limit the periphery of the workpiece material. In practical applications, the blank material may become eccentric or rotate after being placed behind the fixed shaft. The second fixing components limit the periphery of the blank material to prevent it from rotating or becoming eccentric.

[0098] The installation position of each first fixing component corresponds to the layout position of each tool, and an extension area 121 is provided on the outside of each clearance area to constrain the downward rotation of the first fixing component. This extension area is used to accommodate the first fixing component when it flips downward, preventing it from interfering with the stamping tool.

[0099] Working principle: When the upper die assembly is not working, the first fixing component is set around the blank to limit it. When the upper die assembly moves down to press, the first fixing component slowly flips down into the extension area under the action of the pressing tool, so as not to interfere with the operation of the pressing tool, and at the same time to ensure the stability of the blank during the pressing.

[0100] like Figure 4 6-8, In another instance, the lower mold component is configured to include:

[0101] The base plate (also known as the lower mold) 140 is used to provide support force in practical applications. It can directly cooperate with the mounting surface or be set in the hydraulic equipment to cooperate with the working surface.

[0102] The panel 150 is used to provide a mounting surface for the first fixing component, which is spatially corresponding to the upper mold component and provides a mounting surface such that the mounting height of the first fixing component is greater than that of the panel, providing a deeper flipping space for the first fixing component.

[0103] An intermediate plate 160 is set between the front panel and the bottom plate;

[0104] Each plate is provided with multiple clearance holes A 141, clearance hole B 151 and clearance hole C 161 that cooperate with the external structure of the stamping tool. The clearance holes form a longitudinally distributed clearance area after the plates are stacked.

[0105] Each clearance hole has multiple extension holes A142, extension hole B152 and extension hole C162 on its outer side, which cooperate with the downward rotation range of the first fixed component. The extension holes form a longitudinally distributed extension area after the plates are stacked and are connected to the clearance area.

[0106] The base plate is provided with a first fixing hole 143 that mates with one end of the guide component, and the panel and the middle plate are provided with a first guide hole A 153 and a first guide hole B 163 for the guide component to extend out.

[0107] Working principle: The guide assembly connects the plates of the lower die assembly into one unit to ensure the structural stability of the lower die assembly, while ensuring that its height meets the needs of the stamping cutter to penetrate and the first fixing assembly to flip. In practical applications, the plates can also be further connected and fixed by matching screws, etc.

[0108] like Figure 12-13 In another instance, the first fixed component is configured to include:

[0109] The limiting seat 131, which mates with the panel, is used to increase the space so that the limiting member can be flipped.

[0110] An L-shaped limiting member 132 is set within the extension area and partially extends beyond the limiting seat. Here, "set within the extension area" means that its height matches the height of the extension area and the limiting seat to ensure that its rotation is not interfered with. "Partially extending beyond the limiting seat" means that when the limiting member is rotated 90 degrees to the longitudinal direction, one end of it extends beyond the top surface of the limiting seat. The L-shaped structural design makes the end of the limiting member that contacts the blank have a larger area. If one end of the blank has a step, the bending position of the limiting member is exactly matched with the step, thus stretching and limiting its spatial position.

[0111] The limiting seat is connected to the panel by screws. The upper end of the limiting member is provided with a limiting shaft 133 that passes through it laterally. The length of the limiting shaft is configured to be greater than the width of the extension area. In practical applications, the limiting shaft passes through the shaft hole on the limiting member to form a rotatable part with the limiting shaft as the axis. Since the length of the limiting shaft is greater than the width of the extension area, the limiting shaft can be directly set at the top of the extension area to obtain the support part. In order to ensure its smooth rotation, an arc-shaped groove structure that matches the limiting groove can be provided on the panel to limit the position of the limiting shaft and ensure its smooth rotation.

[0112] The bottom of the limiting seat is provided with a limiting groove 134 that cooperates with the limiting shaft. It is an arc-shaped structure used to partially accommodate the limiting groove in order to limit its position. The limiting seat is provided with a flipping groove 135 that cooperates with the flipping position of the limiting member. In actual application, the depth of the flipping groove extending into the center of the limiting seat matches the range of motion of one end of the limiting member when it flips.

[0113] The upper end of the limiting member is provided with a pull hole 136. The pull hole is connected to one side of the limiting seat through an elastic element (not shown). The function of the elastic element is to pull the limiting member back to the initial lateral layout position.

[0114] Working principle: When not in operation, the limiting part is in a horizontal state. When the stamping cutter moves downward, the limiting part flips downward along the limiting axis until it flips 90 degrees and fully enters the extension area. When the stamping cutter moves upward, the limiting part returns to its initial horizontal state under the action of the elastic element.

[0115] like Figure 4-5 9-11 In another instance, the upper module component is configured to include:

[0116] The top plate 220, which is used to cooperate with the external hydraulic station, has a function that is basically the same as that of the bottom plate. Four enclosing pads 230 are set below it to raise the overall height of the upper mold assembly so that it can cooperate with the longer return spring. At the same time, in practical applications, multiple circulating cooling water holes can also be set on the top plate and pads to cooperate with the water cooling holes on each stamping tool to complete the cooling of the blade. In practical applications, in order to ensure the position of the water pipe, a matching water pipe cover plate can also be set in the upper mold assembly to limit or guide its spatial position.

[0117] A mounting plate 240 is provided below the top plate for fixing each stamping tool;

[0118] A guide plate assembly 250 is located below the mounting plate. A mounting shaft is located at the center of the guide plate assembly, and a cover plate 261 is located on the mounting shaft 260. The function of the guide plate assembly is to guide the movement of the guide component. For different parking ratchet structures, the cooperation method between the mounting shaft and the cover plate is different. For parking ratchets with a boss on one side and a large depth of the center hole, the mounting shaft can be placed below and extended into the center hole to further limit the blank and ensure its stability during the stamping process. For blanks with a lower thickness, a cover plate can also be placed below to press the blank from above and ensure the stability of the blank during processing. This structure, together with the mounting shaft and the first fixing component, limits the position of the blank in three ways to ensure that the subsequent processing accuracy meets the requirements.

[0119] Multiple connecting rods 270 are used to connect the guide plate assembly and the mounting plate into a single structure. They are used to connect multiple plates into a single unit so that the components can be linked together under pressure.

[0120] The pad, mounting plate, and guide plate assembly are provided with multiple longitudinally distributed return springs (not shown) at corresponding positions. These return springs are used to return the upper mold assembly to its initial position after the pressure is lost, so that the processed product can be taken out and the next blank to be processed can be placed in.

[0121] Each guide plate assembly and mounting plate is provided with a second guide hole 251 and a second fixing hole 241 that cooperate with the guide component. Each guide plate assembly is provided with a through hole 252 that cooperates with the external structure of the stamping tool. In practical applications, the guide component connects the mounting plate and the bottom in space to ensure that the structure does not shift when each component is working, thus having good structural stability. The top plate and the pad plate can be connected to the mounting plate by matching screws.

[0122] like Figure 14-18 In another example, the stamping tool is configured to include:

[0123] The blade housing 211 has an opening 2110 on one side, which is used to assemble other parts into one piece. The opening is designed to match the processing area, making it easy for the extension and the blade to extend out for stamping operations.

[0124] The tool holder pad 212, which is set inside the tool housing and mates with the mounting surface, is used to adjust the height of the tool.

[0125] At least three sets of stamping cutters 213 are set on the tool holder plate. Setting them into three sets has two effects. When the depth of the ratchet tooth groove and the thickness of the blank are large, the extension length of the three-stage stamping cutters can be set to be inconsistent so that they can cut in layers. That is, the bottom cutter cuts a little more on the outside, the middle cutter cuts a little more inward, and the top cutter cuts to meet the requirements of the depth of the ratchet tooth groove and the external structure, thus ensuring the cutting efficiency and reducing the operation of the cutters. When the depth of the ratchet tooth groove and the thickness of the blank are small, the extension length of the three-stage stamping cutters is set to be consistent so that when the lower cutter wears, the upper cutter can assist in stamping (cutting), ensuring that the processing effect and accuracy meet the usage requirements. At the same time, when replacing, only the lower cutter needs to be replaced, thus controlling the usage cost.

[0126] Each set of stamping cutters includes a stamping blade 214 and a matching cutter holder 215. The cutter holder is used to fix the stamping blade, while also ensuring a gap between adjacent stamping blades and connecting adjacent cutter holders, facilitating the replacement of any blade later.

[0127] Each set of stamping cutters and backing plates is provided with an extension A2130 and an extension B2120 extending out of the opening on the side that mates with the opening. Each stamping cutter has a cutter body 2140 at the front end of the extension that exceeds the length of the extension. The outer edge of the cutter body is provided with a cutting edge 2141. The purpose of providing the extension is to reduce interference with other components during stamping and cutting. At the same time, the extension on the cutter holder can effectively press down the cutter body, reduce its vibration, prevent its breakage, and extend its service life.

[0128] like Figures 19-20 A system for quality inspection of parking ratchet processed by machining molds, comprising:

[0129] Step 1: Trim the edges of the parking ratchet 6 after processing with the mold.

[0130] Step 2: After the trimming operation, the parking ratchet is initially inspected using a testing fixture. This fixture is used to check whether the equipment processing is concentric and whether the tooth depth is consistent. If it is not concentric or inconsistent, it can be recycled as waste.

[0131] Step 3: The parking ratchet that has passed the initial inspection is sent to the intelligent testing production line for a second inspection. This second inspection is used to perform a fine inspection on the parking ratchet after the initial inspection to ensure that its processing accuracy meets the usage requirements.

[0132] In step two, the detection fixture is configured to include a cooperating movable mold 5 and a fixed mold (not shown);

[0133] The lower end face of the fixed mold is connected to the telescopic mechanism (not shown). The upper end face of the fixed mold is provided with a hollow shaft (not shown) that can extend into the center hole of the parking ratchet. The free end of the hollow shaft is provided with a cap (not shown) for fixing the blank material by means of a thread. The hollow shaft is provided with a first boss (not shown) for raising the spatial position of the parking ratchet.

[0134] The movable mold center is provided with a through hole 510 for the parking ratchet to pass through. A plurality of second fixing components 520 are arranged around the through hole to cooperate with the ratchet tooth groove. One end of the second fixing component is fitted with the external structure of the tooth groove, and this end is fitted with the tooth groove of the standard parking ratchet with a small clearance. The other end is fixedly connected to the movable groove. In actual application, when the second fixing component, the parking ratchet, and the through hole are concentric, if the parking ratchet can pass smoothly through the second fixing mechanism, it is considered that its concentricity and machining depth meet the requirements of rough inspection. This can be achieved by setting a corresponding sensor 530 on the free end of each fixing component that cooperates with the parking ratchet.

[0135] The outer edge or lower end of the movable mold is provided with a matching meshing tooth (not shown), which is connected to the motor (not shown) through a matching transmission component.

[0136] The motor, telescopic mechanism, and sensor are configured to communicate with a first control terminal (not shown);

[0137] In step two, the initial inspection process includes:

[0138] S20, place the parking ratchet on the hollow shaft of the fixed mold, tighten the cap, and complete the fixing of the parking ratchet;

[0139] S20, control the moving module to descend, and monitor the pressure in real time through the sensor on the second fixed component during the descent of the moving module. After the sensor detects the pressure, it transmits the corresponding pressure signal to the first control terminal.

[0140] S21, the first control terminal switches the working state of the telescopic mechanism, and switches the working state of the telescopic mechanism again after the movable module moves to the predetermined position.

[0141] In step S22, the first control terminal starts the motor to adjust the angle of the movable mold in steps and counts the number of adjustments. After the movable mold completes the angle adjustment, it returns to step S20. This process continues until the parking ratchet can pass through the two fixed components or the predetermined number of angle adjustments is reached. At this point, the first control terminal issues a notification that the detection is complete. Using this detection method, after ensuring that the parking ratchet and the second fixed component are concentrically arranged, the number of angle adjustments can be set according to the spacing and curvature of each tooth groove. If the second fixed component can smoothly pass through the parking ratchet, its concentricity and machining depth are considered to meet the requirements of the rough inspection. Otherwise, the motor drives the second fixed component to rotate, and the degree of rotation can be adjusted according to the tooth groove spacing. If the second fixed component still cannot smoothly pass through the parking ratchet after the predetermined number of angle adjustments, its concentricity and machining depth are considered not to meet the requirements of the rough inspection, and manual inspection or direct recycling can be performed.

[0142] In another example, in step three, the intelligent inspection production line is configured to include:

[0143] The testing platform is provided with a positioning shaft that can extend into the center hole of the parking ratchet. The positioning shaft is provided with matching marking points, and the positioning shaft is provided with a second protrusion that raises the spatial position of the parking ratchet.

[0144] An image acquisition mechanism is positioned above the detection platform and spatially aligned with the center of the positioning axis;

[0145] A robotic arm is installed on one side of the testing table to place the parking ratchet to be tested on the positioning shaft or to flip the parking ratchet for testing.

[0146] A labeling machine installed on one side of the testing table to add labels to defective parking ratchet wheels;

[0147] A second control terminal is set on one side of the detection table and communicates with the image acquisition mechanism, the robotic arm, and the labeling machine.

[0148] The testing process of the intelligent testing production line is configured to include:

[0149] S30, the second control terminal controls the robot arm to pick up the parking ratchet to be tested and place the parking ratchet on the second boss of the positioning shaft;

[0150] S31, the second control terminal controls the image acquisition mechanism to face the surface of the parking ratchet side to acquire images, and controls the image acquisition mechanism to send the acquired images to the second control terminal;

[0151] S32, the second control terminal acquires the marker points in the received image, processes the image with the marker points as the center, to obtain feature points related to the parking ratchet, and compares the extracted feature points with the standard image feature points stored in the second control terminal to judge the quality of one side of the parking ratchet.

[0152] S33, the second control terminal controls the robotic arm to flip the parking ratchet, repeating steps S31 to S32, to judge the quality of the other side of the parking ratchet;

[0153] S34, the second control terminal, based on the quality judgment of both sides of the parking ratchet, if the error is within the predetermined range, controls the machinery to send the parking ratchet to the finished product conveyor line; otherwise, it sends the parking ratchet to the recycling conveyor line. In practical applications, the quality judgment label on each side can be used to determine whether it should be recycled or undergo secondary processing. If the quality of both sides does not meet the requirements, it is directly recycled. If there is only one side and the feature point matching degree is high, it can be reworked through manual trimming in the secondary processing before intelligent quality inspection. By setting up intelligent quality inspection, manpower is reduced while ensuring that the detection accuracy meets the usage requirements.
