Description

A high-precision anti-misalignment structure for cycloidal rotary gear machining Technical Field

[0001] This invention belongs to the field of gear processing technology, specifically a high-precision anti-misalignment structure for cycloidal gear machining. Background Technology

[0002] In the field of mechanical manufacturing, internal gears, as key transmission components, are widely used in various mechanical equipment, automobiles, aerospace, and many other industries. Taking automotive synchronizer sleeves as an example, they play a crucial role in automotive transmissions, achieving smooth gear shifting through precise meshing with gears. With the continuous development of the automotive industry, the precision requirements for automotive synchronizer sleeves are becoming increasingly stringent. Cycloidal rotary machining, as a high-efficiency and high-precision gear machining method, has received increasing attention in the processing of automotive synchronizer sleeves.

[0003] The basic principle of cycloidal gear machining is to utilize cycloidal motion to form the desired gear tooth profile through the relative motion between the tool and the workpiece. In the machining of automotive synchronizer bushings, the tool moves precisely along a cycloidal trajectory, interacting with the bushing blank to gradually cut out a high-precision tooth profile. However, during machining, the tool's movement trajectory is closely related to the gear tooth profile shape. Any misalignment will directly affect the machining accuracy of the bushing, and consequently, the performance of the entire automotive transmission, leading to problems such as shift shock and increased noise.

[0004] Traditional cycloidal rotary machining equipment and processes have certain limitations in terms of precision control. For example, each impact between the tool and the workpiece can cause misalignment of the gear during machining. These misalignments may manifest as pitch error, tooth profile error, or tooth direction error, causing the transmission accuracy, smoothness, and load-bearing capacity of components such as gear sleeves to fail to meet design requirements.

[0005] Therefore, in the face of the misalignment problem in traditional cycloidal gear machining and the many adverse effects it brings, the development of a high-precision anti-misalignment structure for cycloidal gear machining has become an urgent need in the field of mechanical manufacturing. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a high-precision anti-misalignment structure for cycloidal gear machining, which can reduce misalignment errors during gear sleeve machining and improve the machining accuracy and quality of the gear sleeve.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] A high-precision anti-misalignment structure for cycloidal gear machining includes a workpiece shaft with an installation groove inside. The installation groove houses a data acquisition unit, a limiting unit, a control unit, and an alarm unit. The data acquisition unit collects the pressure distribution on the workpiece within a preset speed range. The limiting unit applies radial pressure to the workpiece based on the magnitude of the centrifugal force. The control unit determines whether the workpiece installation is abnormal based on the pressure distribution and controls the operation of the alarm unit. The alarm unit sends out alarm notifications.

[0009] The above approach has the following beneficial effects:

[0010] 1. This solution uses a data acquisition unit inside the mounting slot to monitor the force on the workpiece in real time. It can accurately capture abnormal pressure distribution within a preset speed range. For example, at the initial stage of startup, before the workpiece is cut, the pressure on the workpiece is detected to determine the workpiece installation status. If there are foreign objects (such as chips) between the workpiece and the side wall of the mounting slot during the workpiece installation process, the pressure distribution will show an asymmetrical peak. The control unit will use this to determine that the installation is abnormal. When the workpiece installation is abnormal, the control alarm unit will sound an alarm to remind the staff to make adjustments.

[0011] 2. This solution uses a limiting mechanism to automatically adjust the contact surface pressure according to changes in centrifugal force, thereby ensuring the free rotation of the workpiece while forming a radial flexible constraint, effectively counteracting radial movement during the processing.

[0012] Furthermore, the limiting unit includes several extrusion grooves circumferentially formed on the inner wall of the mounting groove. Each extrusion groove has an arc-shaped block slidingly fitted inside it. Each extrusion groove is connected to a limiting groove. A limiting ball and an inclined block slidely fitted inside the limiting groove. The limiting ball abuts against the arc-shaped block and the inclined block respectively. When the inclined block moves toward the limiting ball, the limiting ball pushes the arc-shaped block toward the mounting groove. A pressure applying mechanism is provided at the end of the inclined block away from the limiting ball. The pressure applying mechanism is used to convert the centrifugal force generated by the rotation of the workpiece into an extrusion force on the inclined block.

[0013] Beneficial effects: The pressure-applying mechanism directly converts the centrifugal force of the workpiece rotation into the axial thrust of the inclined block, which is then transmitted through a three-stage transmission mechanism consisting of the inclined plane, ball joint, and arc block. This force-enhancing mechanism significantly improves the clamping force, ensuring the stability of the workpiece during high-speed rotation and effectively preventing workpiece loosening and misalignment caused by centrifugal force.

[0014] The clamping force generated is positively correlated with the rotational speed. As the rotational speed increases, the clamping force automatically increases, perfectly matching the needs of high-speed machining scenarios. This ensures that the workpiece receives sufficient radial constraint force at different rotational speeds, thereby effectively reducing radial runout and improving machining accuracy.

[0015] Each time the cutting tool impacts the workpiece, a momentary increase in centrifugal force is generated. The pressure mechanism can quickly respond to this instantaneous change, generating a corresponding increase in clamping force to immediately secure the workpiece. This dynamic response mechanism effectively reduces workpiece vibration and misalignment caused by impact forces during machining, significantly improving the stability and accuracy of the machining process.

[0016] Due to the structural relationship between the arc block, the limiting ball, and the inclined block, the inclined block is easier to insert between the limiting ball and the limiting groove to push the limiting ball to move, while the limiting ball is less likely to push the inclined block to move in the opposite direction. This mechanical characteristic can ensure that the arc block maintains the pressure on the workpiece.

[0017] Furthermore, the pressure-applying mechanism includes a movable groove, one end of which is connected to a limiting groove, and the other end of which is connected to a sliding groove, in which a counterweight is placed; a lever is rotatably connected in the movable groove, one end of which abuts against an inclined block, and the other end of which contacts the counterweight, wherein the distance from the counterweight to the fulcrum of the lever is greater than the distance from the inclined block to the fulcrum of the lever.

[0018] Beneficial effects: The combination of the lever's labor-saving effect and the counterweight's centrifugal force amplifies a small centrifugal force into a larger axial thrust, significantly enhancing the clamping force on the workpiece and ensuring its stability under high-speed rotation and cutting impact, effectively preventing misalignment and vibration. The transient impact generated each time the tool rotates to strike the workpiece will act on the counterweight, thus transforming into a radial constraint force that strengthens the arc-shaped block's hold on the workpiece.

[0019] Furthermore, a ball head is provided at one end of the lever near the inclined block.

[0020] Beneficial effects: The ball joint structure ensures that the torque generated by the lever is precisely oriented in the direction of movement of the inclined block, avoiding force dispersion or deviation, thereby more effectively pushing the inclined block to move and improving the efficiency of clamping force transmission.

[0021] Furthermore, the end of the movable groove away from the inclined block is connected to a through groove, and a U-shaped block is slidably fitted inside the through groove. One end of the U-shaped block is provided with a gradient surface, which contacts the lever. The other end of the U-shaped block is connected to a pre-pressure mechanism, which is used to pre-store negative pressure.

[0022] Beneficial effects: When the lever deflects, the U-shaped block is subjected to negative pressure siphon and slides continuously into the movable groove along the through groove. The gradient surface dynamically engages with the lever and continuously engages with the lever until the springback of the lever is completely restricted, thereby completing the clamping and fixing of the workpiece.

[0023] Furthermore, the pre-compression mechanism includes a pre-compression chamber with a U-shaped structure. One end of the pre-compression chamber is slidably engaged with a U-shaped block, and the other end of the pre-compression chamber is provided with a piston rod and a limiting mechanism. The piston rod is slidably engaged with the pre-compression chamber, and the limiting mechanism is used to restrict the piston rod from resetting.

[0024] Beneficial effects: By pulling the piston rod outward, a negative pressure is gradually generated in the pre-compression chamber. When the piston rod triggers the limiting mechanism, the limiting mechanism fixes the piston rod, thereby creating a stable negative pressure environment in the pre-compression chamber. This stable negative pressure provides a continuous pulling force to the U-block, ensuring that the U-block can stably restrict the lever's reset.

[0025] Furthermore, the limiting mechanism includes a locking groove on one side of the piston rod and a transverse groove on one side of the pre-compression chamber. A locking block and a spring are installed in the transverse groove. The locking block slides with the transverse groove, and the spring is located between the locking block and the inner wall of the transverse groove. When the locking groove passes through the transverse groove, the locking block engages with the locking groove.

[0026] Beneficial effects: The limiting mechanism can reliably fix the piston rod in the preset position by engaging the locking block with the locking groove, thereby ensuring that a stable negative pressure is formed and maintained in the pre-compression chamber.

[0027] Furthermore, the piston rod is cylindrical.

[0028] Beneficial effects: When it is necessary to remove the workpiece, continue to pull the piston rod outward, the locking groove passes over the locking block and squeezes the locking block back into the horizontal groove, and then rotate the piston rod to make the locking groove deviate from the horizontal groove, so as to easily release the locking block limit. The operation is simple and convenient.

[0029] Furthermore, the alarm unit is an audible and visual alarm, which is used to send an audible and visual alarm prompt when the control unit determines that the workpiece is installed abnormally, so as to remind the staff to make timely adjustments.

[0030] Furthermore, a sealing element is installed inside the pre-compression chamber to prevent negative pressure leakage within the pre-compression chamber. Attached Figure Description

[0041] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0042] The following detailed description illustrates the specific implementation method:

[0043] The embodiment is basically shown in Figures 1-6: A high-precision anti-misalignment structure for cycloidal gear machining includes a workpiece shaft 1, which is mounted on a cycloidal gear machining machine (both the workpiece shaft 1 and the machine tool are existing technologies and will not be described in detail here). A mounting groove 101 is provided inside the workpiece shaft 1, and a data acquisition unit, a limit unit, a control unit, and an alarm unit are installed within the mounting groove 101. The data acquisition unit is used to collect the pressure distribution on the workpiece within a preset speed range; specifically, in this embodiment, the data acquisition unit uses a miniature MEMS pressure sensor array, which is arranged on the inner wall of the mounting groove 101 to monitor the 360° circumferential pressure distribution of the workpiece in real time.

[0044] The limiting unit is used to apply radial pressure to the workpiece based on the magnitude of the centrifugal force acting on it. Specifically, the limiting unit includes several extrusion grooves circumferentially formed on the inner wall of the mounting groove 101. Arc-shaped blocks 102 are slidably fitted within each extrusion groove. Each extrusion groove is connected to a limiting groove 103. A limiting ball 104 and an inclined block 105 are slidably fitted within each limiting groove 103. The limiting ball 104 abuts against the arc-shaped block 102 and the inclined block 105, respectively. Referring to Figure 5, the inclined block 105... The inclined surface abuts against the limiting ball 104. The cross-section of the limiting groove 103 is generally inverted right angle. The area at the bottom of the limiting ball 104 is an acute angle area, that is, the space gradually shrinks. When the inclined block 105 moves toward the limiting ball 104, the limiting ball 104 pushes the arc block 102 toward the mounting groove 101. A pressure applying mechanism is provided at the end of the inclined block 105 away from the limiting ball 104. The pressure applying mechanism is used to convert the centrifugal force generated by the rotation of the workpiece into the extrusion force on the inclined block 105.

[0045] Specifically, the pressure-applying mechanism includes a movable groove 107. As shown in Figures 4, 5, and 6, one end of the movable groove 107 is connected to the limiting groove 103, and the other end of the movable groove 107 is connected to a sliding groove 110. A counterweight 109 is slidably fitted in the sliding groove 110. Preferably, in this embodiment, the counterweight 109 has a spherical outer surface and can be made of tungsten alloy, which has the advantages of high density, wear resistance, and impact resistance. A lever 106 is rotatably connected within the movable groove 107. Specifically, the lever 106 is rotatably connected within the movable groove 107 via a rotating shaft. In this embodiment, both the lever 106 and the rotating shaft are made of high-nitrogen stainless steel. The rotating shaft serves as the fulcrum of the lever 106. One end of the lever 106 abuts against the inclined block 105. As shown in Figure 5, a ball head 108 is provided at the bottom of the lever 106. The ball head 108 and the lever 106 are designed as an integrated unit. The top of the lever 106 contacts the counterweight 109. The length of the counterweight 109 from the fulcrum of the lever 106 is greater than the length of the inclined block 105 from the fulcrum of the lever 106. That is, the section from the counterweight 109 to the fulcrum on the lever 106 is a power arm, and the other section is a resistance arm. The power arm is much longer than the resistance arm.

[0046] Preferably, the end of the movable groove 107 away from the inclined block 105 is connected to a through groove 112. A U-shaped block 111 is slidably fitted within the through groove 112. One end of the U-shaped block 111 has a gradient surface that contacts the lever 106. The other end of the U-shaped block 111 is connected to a pre-pressing mechanism for pre-storing negative pressure. Specifically, the pre-pressing mechanism includes a pre-pressing cavity 113, which has a U-shaped structure. One end of the pre-pressing cavity 113 is slidably fitted with the U-shaped block 111, and the other end of the pre-pressing cavity 113 is provided with a piston rod 114 and a limiting mechanism. The piston rod 114 is slidably fitted with the pre-pressing cavity 113, and the limiting mechanism is used to restrict the piston rod 114 from resetting. Preferably, a sealing element is provided inside the pre-pressing cavity to prevent leakage of negative pressure within the pre-pressing cavity. In this embodiment, the sealing element is a sealing ring, which is installed between the U-shaped block and the inner wall of the pre-pressing cavity.

[0047] Specifically, the limiting mechanism includes a locking groove 115 on one side of the piston rod 114, and a transverse groove on one side of the pre-compression chamber 113. A locking block 116 and a spring 117 are disposed within the transverse groove. The locking block 116 slides within the transverse groove, and both ends of the spring 117 are respectively bonded and fixed to the locking block 116 and the inner wall of the transverse groove. When the piston rod 114 moves, the locking groove 115 passes through the transverse groove, and the locking block engages with the locking groove 115. Preferably, in this embodiment, the piston rod 114 is cylindrical.

[0048] The control unit is used to determine whether the workpiece installation is abnormal based on the pressure distribution and to control the operation of the alarm unit. Specifically, at the initial startup stage, before the workpiece is cut, the acquisition unit detects the pressure on the workpiece to determine the workpiece installation status. If there are foreign objects (such as chips) between the workpiece and the side wall of the mounting groove 101, the pressure distribution will show an asymmetrical peak. Based on this, the control unit determines that the installation is abnormal and triggers the alarm unit to issue an alarm prompt.

[0049] The alarm unit is used to send alarm prompts externally. Preferably, in this embodiment, the alarm unit is an audible and visual alarm, which is used to send an audible and visual alarm prompt when the control unit determines that the workpiece is installed abnormally, so as to remind the staff to make timely adjustments.

[0050] The specific implementation process is as follows:

[0051] The workpiece is mounted on the workpiece shaft 1. By pulling the piston rod 114 outward, a negative pressure is formed in the pre-compression chamber 113. The piston rod 114 triggers the limiting mechanism (the locking block 116 engages with the locking groove 115), fixing the piston rod 114 and forming a stable negative pressure environment. Under the action of negative pressure, the U-shaped block 111 tends to move into the movable groove 107.

[0052] Rotating the workpiece shaft 1, the acquisition unit (micro-MEMS pressure sensor array) begins monitoring the pressure distribution on the workpiece within a preset rotational speed range (0-preset rotational speed in this embodiment). Initially, before cutting, the acquisition unit detects the pressure on the workpiece to determine its installation status. If foreign objects (such as chips) exist between the workpiece and the sidewall of the mounting groove 101, the pressure distribution will exhibit asymmetrical peaks. Based on this, the control unit determines an installation abnormality and triggers the alarm unit to issue an alarm.

[0053] When the workpiece rotates, centrifugal force acts on the counterweight 109, causing it to move outward within the slide groove 110, pushing the lever 106 to rotate around the fulcrum. The other end of the lever 106 pushes the inclined block 105 towards the limiting ball 104, which in turn pushes the arc-shaped block 102 towards the mounting groove 101, applying radial pressure to the workpiece. The pressure-applying mechanism applies clamping force through a three-stage transmission mechanism of inclined plane-spherical hinge-arc block 102, ensuring the stability of the workpiece during high-speed rotation.

[0054] Each time the tool impacts the workpiece, a momentary increase in centrifugal force is generated. The pressure mechanism responds quickly, instantly increasing the clamping force to reinforce the workpiece clamping state and reduce vibration and misalignment caused by the impact force. Each time the lever 106 deviates after impact, the U-shaped block 111 will move into the movable groove 107 under the negative pressure in the pre-compression chamber 113, thereby preventing the lever 106 from rebounding.

[0055] After processing, when the workpiece needs to be removed, the workpiece shaft 1 stops rotating, the centrifugal force disappears, and by continuing to pull the piston column 114 outward, the engaging groove 115 passes over the engaging block 116 and pushes the engaging block 116 back into the transverse groove. Then, the piston column 114 is rotated to make the engaging groove 115 deviate from the transverse groove, releasing the piston column 114. The piston column 114 moves back into the pre-compression chamber 113 to reset, thus releasing the limiting position of the engaging block and facilitating the reset of the U-shaped block 111. At this time, the U-shaped block 111 is pulled outward to disengage from the lever 106, releasing the constraint of the lever 106 (ball head 108-sloping block 105-limiting ball 104) on the arc-shaped block 102. The arc-shaped block 102 will then be released from its constraint on the workpiece, making it easier to remove the workpiece.

[0056] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific structures and / or characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
