Description

Technical Field

[0001] This application relates to the field of gear press-fitting technology, specifically a gear press-fitting device based on camera gear splitting and a servo press. Background Technology

[0002] Gear press fitting typically involves the application of pressure or torque. Using specialized press fitting equipment (such as servo presses, hydraulic presses, etc.), the gear is pressed onto the shaft, creating a tight fit between the gear and the shaft. This fit not only ensures the fixed position of the gear on the shaft but also ensures that the gear can smoothly and accurately transmit power and torque during operation.

[0003] In gear pressing, the process often involves a combination of laser sensor tooth splitting and traditional hydraulic equipment, or a combination of mechanical tooth splitting mechanism and servo press. However, mechanical tooth splitting modules achieve tooth splitting through physical positioning pins or shift forks, requiring multiple sets of fixtures to be customized for different gear outer diameters and tooth groove sizes. During production changes, manual disassembly and adjustment are necessary, which is time-consuming and prone to human error. Secondly, although servo presses can achieve closed-loop control of pressure and displacement, they are limited by the positioning accuracy of the mechanical tooth splitting mechanism. Even slight gear misalignment during pressing may cause damage during the pressing process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a gear pressing device based on camera tooth division and servo press, which has the advantages of strong applicability and high pressing accuracy, and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a gear pressing device based on camera toothing and a servo press, comprising a set of support frames arranged in a matrix, two first linear modules fixedly connected to the top of the set of support frames, the bottom end of each first linear module being fixedly connected to the top end of the support frame adjacent to it, the two first linear modules being arranged symmetrically, a second linear module being slidably connected to the two first linear modules, a mounting frame being slidably connected to the second linear module, a servo hydraulic cylinder being fixedly mounted on one side of the mounting frame, and a mounting plate being fixedly connected to the output end of the servo hydraulic cylinder;

[0006] The bottom of the mounting plate is provided with a clamping mechanism;

[0007] A detection mechanism is provided on one side of the installation plate;

[0008] A preheating frame and a pressing frame are respectively provided between a group of support frames, and the preheating frame and the pressing frame are fixedly connected to each other;

[0009] The upper surface of the preheating rack is provided with a preheating mechanism;

[0010] The upper surface of the pressing frame is provided with two symmetrically arranged support mechanisms;

[0011] A shaft fixing mechanism is provided on one side of the pressing frame.

[0012] Furthermore, the clamping mechanism includes a motor, which is fixedly connected to the bottom of the mounting plate. A clamping frame is fixedly connected to the output end of the motor. A first bidirectional threaded rod is rotatably connected between the two inner sidewalls of the clamping frame. Moving blocks are threaded to both ends of the first bidirectional threaded rod. Both moving blocks are slidably connected to the clamping frame. A clamping arc plate is installed at the bottom of both moving blocks. The outer surface of the two clamping arc plates is serrated. One end of the first bidirectional threaded rod is fixedly connected to the output end of an external motor.

[0013] The above scheme enables the first bidirectional threaded rod to drive the clamping arc plate, thereby enabling the transfer of gears with different gears.

[0014] Furthermore, the testing mechanism includes a testing frame, which is fixedly connected to the mounting plate. An electric push rod is fixedly installed at the bottom of the testing frame, and an angle frame is fixedly installed at the output end of the electric push rod. An angle shaft is rotatably connected between the two inner sidewalls of the angle frame. An industrial camera module is installed on the outer surface of the angle shaft, and one end of the angle shaft is fixedly connected to the output end of an external motor.

[0015] The above solution allows the electric actuator to adjust the height of the industrial camera module, and the angle axis to adjust its illumination direction, making it suitable for the inspection of gears of different sizes.

[0016] Furthermore, the preheating mechanism includes a second bidirectional threaded rod, the two ends of which are rotatably connected to the two inner sidewalls of the preheating frame, and the two ends of the outer surface of the second bidirectional threaded rod are threadedly connected to a spacing adjustment plate. Both spacing adjustment plates are slidably connected to the preheating frame. A third bidirectional threaded rod is rotatably connected between the inner top wall and the inner bottom wall of the two spacing adjustment plates. Both ends of the outer surface of the two third bidirectional threaded rods are threadedly connected to a fixing plate. A high-frequency heater is installed on one side of each fixing plate.

[0017] With the above scheme and settings, non-contact heating of the gear can be achieved by using a high-frequency heater. During heating, the motor drives the gear to rotate slowly, which ensures that it is heated evenly.

[0018] Furthermore, a V-shaped mating groove is provided on one side of the pressing frame, and the shaft fixing mechanism includes a power frame, which is fixedly connected to the pressing frame. The power frame is located on one side of the V-shaped mating groove, and a fixed hydraulic cylinder is installed inside the power frame. A limit block is fixedly installed at the output end of the fixed hydraulic cylinder, and the limit block is located inside the V-shaped mating groove.

[0019] The above solution, by setting up a fixed hydraulic cylinder, enables the limit block to make close contact with the shaft, thereby fixing the shaft.

[0020] Furthermore, the supporting mechanism includes an electric slide rail, which is fixedly connected to the upper surface of the pressing frame. A cylinder is slidably connected to the electric slide rail. A sleeve perpendicular to the pressing frame is fixedly connected to the output end of the cylinder. An insert rod is slidably inserted into the sleeve. A compression spring is provided between the insert rod and the sleeve. An L-shaped support plate is fixedly installed at the top of the insert rod.

[0021] The above solution, through the setting of the support mechanism, can fix the gear above the assembly shaft, which facilitates the subsequent pressing work.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This gear pressing device, based on camera-based gear splitting and servo press, replaces the traditional mechanical or laser positioning method with industrial camera vision gear splitting technology. It can automatically identify the gear model, number of teeth and keyway position, and can adapt to multiple specifications of gears without changing physical fixtures or adjusting mechanical structure, significantly shortening changeover time.

[0024] The adjustable industrial camera module set up by the testing agency can complete the positioning of keyways of gears of different sizes and the screening of surface defects before pressing, so as to avoid defective products from flowing into subsequent processes and wasting processing time. During the pressing process, the axial displacement and meshing status of the gears are monitored in real time, forming a closed-loop control of testing, pressing and verification, which greatly improves the product qualification rate.

[0025] The preheating mechanism adopts high-frequency induction heating technology, which achieves non-contact uniform heating of the gear through an adjustable-gap high-frequency heater array. Combined with the motor-driven gear slow rotation, it eliminates the risk of thermal stress concentration and facilitates subsequent pressing and assembly. After heating, the gear is positioned above the shaft by the support mechanism. During the pressing process, the sleeve and insert rod guide structure ensures the verticality of the pressing and avoids damage from off-center load.

[0026] The shaft fixing mechanism, consisting of a V-groove and a limiting block, can vertically fix shafts of different diameters. The electric slide rail and cylinder drive system of the support mechanism can automatically adjust the position of the L-shaped support plate according to the shaft diameter. With the downward control of the servo hydraulic cylinder, the gear keyway and shaft spline are precisely aligned, avoiding workpiece scrap or damage caused by misalignment.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a gear pressing device based on camera toothing and servo press includes a set of support frames 1 arranged in a matrix. Two first linear modules 2 are fixedly connected to the top of the set of support frames 1. The bottom end of each first linear module 2 is fixedly connected to the top end of the support frame 1 that is close to it. The two first linear modules 2 are arranged symmetrically. A second linear module 3 is slidably connected to the two first linear modules 2. A mounting frame 4 is slidably connected to the second linear module 3. A servo hydraulic cylinder 5 is fixedly installed on one side of the mounting frame 4. A mounting plate 6 is fixedly connected to the output end of the servo hydraulic cylinder 5.

[0045] Please see Figure 1 , Figure 2 and Figure 4 The bottom of the mounting plate 6 is equipped with a clamping mechanism 7, which enables the clamping and transfer of gears. The clamping mechanism 7 includes a motor 701, which is fixedly connected to the bottom of the mounting plate 6. The output end of the motor 701 is fixedly connected to a clamping frame 702. A first bidirectional threaded rod 703 is rotatably connected between the two inner sidewalls of the clamping frame 702. The two ends of the first bidirectional threaded rod 703 are respectively threaded with moving blocks 704. Both moving blocks 704 are slidably connected to the clamping frame 702. The bottom of each of the two moving blocks 704 is equipped with a clamping arc-shaped plate 705, and the outer surface of the two clamping arc-shaped plates 705 is serrated. One end of the first bidirectional threaded rod 703 is fixedly connected to the output end of an external motor. In the initial stage, the first linear module 2 and the second linear module 3 can drive the clamping mechanism 7 to come above the gear. Then, the servo hydraulic cylinder 5 drives the clamping mechanism 7 to descend, so that the two clamping arc plates 705 enter the inner hole of the gear. By driving the first bidirectional threaded rod 703 away from each other, the inner hole wall of the gear is tightly fitted, thereby achieving the purpose of clamping the gear. The first linear module 2 drives the gear to move above the preheating rack 9. The first bidirectional threaded rod 703 drives the clamping arc plates 705, which can realize the transfer of gears of different gears.

[0046] Please see Figure 1 , Figure 2 and Figure 5A detection mechanism 8 is provided on one side of the mounting plate 6. The detection mechanism 8 includes a detection frame 801, which is fixedly connected to the mounting plate 6. An electric actuator 802 is fixedly installed at the bottom of the detection frame 801. An angle frame 803 is fixedly installed at the output end of the electric actuator 802. An angle shaft 804 is rotatably connected between the two inner side walls of the angle frame 803. An industrial camera module 805 is installed on the outer surface of the angle shaft 804. One end of the angle shaft 804 is fixedly connected to the output end of an external motor. In the initial stage, before the clamping mechanism 7 clamps the gear, the industrial camera module 805 can detect surface defects of the gear and record the keyway position of the gear. The electric actuator 802 can adjust the height of the industrial camera module 805, and the angle shaft 804 can adjust its irradiation direction. It is suitable for detecting gears of different sizes. Through the detection mechanism 8, the keyway position of the gear can be detected, and surface defects of the gear can also be detected.

[0047] Please see Figure 1 , Figure 6 and Figure 7 A preheating frame 9 and a pressing frame 10 are respectively arranged between a set of support frames 1. The preheating frame 9 and the pressing frame 10 are fixedly connected. The upper surface of the preheating frame 9 is provided with a preheating mechanism 11, which can heat the gear before assembly, facilitating the subsequent assembly of the gear and shaft. The preheating mechanism 11 includes a second bidirectional threaded rod 111. The two ends of the second bidirectional threaded rod 111 are rotatably connected to the two inner side walls of the preheating frame 9, respectively. The two ends of the outer surface of the second bidirectional threaded rod 111 are threadedly connected to the spacing adjustment plates 112. Both spacing adjustment plates 112 are slidably connected to the preheating frame 9, which can realize the heating of gears of different diameters. The inner top wall and inner bottom wall of the two spacing adjustment plates 112 are respectively connected to the spacing adjustment plates 112. A third bidirectional threaded rod 113 is rotatably connected between the two gears. Both ends of the outer surface of the two third bidirectional threaded rods 113 are threaded with fixing plates 114. A high-frequency heater 115 is installed on one side of each fixing plate 114. The setting of the third bidirectional threaded rod 113 allows for adjustment of the distance between the two close high-frequency heaters 115, which is suitable for gears of different thicknesses. One end of the third bidirectional threaded rod 113 and the second bidirectional threaded rod 111 are fixedly connected to the output end of the external motor. With the above settings, the gear can be heated non-contactly by the high-frequency heaters 115. During heating, the motor 701 drives the gear to rotate slowly, which ensures that it is heated evenly.

[0048] Please see Figure 1 , Figure 6 and Figure 7The pressing frame 10 has a shaft fixing mechanism 13 on one side to fix the assembly shaft. Two symmetrically arranged support mechanisms 12 are provided on the upper surface of the pressing frame 10 to facilitate the support and fixing of the heated gear. A V-shaped mating groove 101 is formed on one side of the pressing frame 10. The shaft fixing mechanism 13 includes a power frame 131, which is fixedly connected to the pressing frame 10 and located on one side of the V-shaped mating groove 101. A fixing hydraulic cylinder 132 is installed inside the power frame 131, and a limit block 133 is fixedly installed at the output end of the fixing hydraulic cylinder 132. The limit block 133 is located inside the V-shaped mating groove 101. By placing the shaft to be mated in the V-shaped mating groove 101 and driving the fixing hydraulic cylinder 132 to move the limit block 133, vertical fixing of the shaft can be achieved. Because the V-shaped mating groove 101 has a V-shaped structure… The device is suitable for pressing shafts of different diameters. The fixed hydraulic cylinder 132 enables tight contact between the limit block 133 and the shaft, thus fixing the shaft. The support mechanism 12 includes an electric slide rail 121, which is fixedly connected to the upper surface of the pressing frame 10. The electric slide rail 121 is slidably connected to a cylinder 122. The output end of the cylinder 122 is fixedly connected to a sleeve 123 that is perpendicular to the pressing frame 10. A rod 124 is slidably inserted into the sleeve 123. A compression spring 125 is provided between the rod 124 and the sleeve 123. An L-shaped support plate 126 is fixedly installed at the top of the rod 124. After fixing shafts of different diameters, the position of their V-shaped mating groove 101 is different. The electric slide rail 121 can drive the L-shaped support plate 126 to move to one side of the shaft, and the cylinder 122 can push the L-shaped support plate 126 above the shaft.

[0049] Please see Figure 6 , Figure 7 and Figure 8 After the clamping mechanism 7 contacts the bottom of the gear with the bottom of the L-shaped support plate 126, the cylinder 122 then fixes both sides of the gear. Subsequently, the first bidirectional threaded rod 703 drives the clamping arc plate 705 to move closer together, and the servo hydraulic cylinder 5 drives it to disengage from the gear's inner hole and move it above the gear. Then, the first bidirectional threaded rod 703 rotates, driving the clamping arc plate 705 to move away from each other, so that the clamping arc plate 705 is above the gear. The servo hydraulic cylinder 5 drives the clamping arc plate 705 to press down and drive the gear to descend. The sleeve 123 and the insert rod 124 can provide guidance so that the heated gear and shaft can be pressed together. Next, the detection mechanism 8 has recorded the gear keyway position. Before the preheating ends and the pressing work begins, the detection mechanism 8 detects and records the spline position of the shaft. After the preheating is completed, the motor 701 should drive the gear clamped by the clamping mechanism 7 to rotate, so that the keyway and spline are on the same axis, ensuring the normal progress of the pressing work.

[0050] It should be noted that all electrical components are connected to an external control system.

[0051] The working principle of the above embodiment is as follows: After the device is started, the two first linear modules 2 operate synchronously, driving the second linear module 3 to move above the gear feeding area. The second linear module 3 drives the mounting frame 4 to move laterally, so that the clamping mechanism 7 is accurately positioned directly above the gear to be pressed. The electric push rod 802 of the detection mechanism 8 pushes the angle frame 803 down, and the industrial camera module 805 is adjusted to the gear surface. The external motor drives the angle shaft 804 to rotate, so that the camera module focuses on the gear end face, records the keyway position and scans the tooth surface defects. The servo hydraulic cylinder 5 drives the mounting plate 6 to descend, and the two clamping arc plates 705 of the clamping mechanism 7 enter the gear inner hole. The external motor drives the first bidirectional threaded rod 703 to rotate, so that the two moving blocks 704 drive the clamping arc plates 705. Expanding outwards, the serrated outer surface tightly meshes with the inner wall of the gear, completing the gear gripping. Subsequently, the servo hydraulic cylinder 5 lifts the gear to a safe height, and the first linear module 2 moves the gear above the preheating frame 9. The second bidirectional threaded rod 111 of the preheating mechanism 11 adjusts the spacing of the spacing adjustment plate 112 to match the gear diameter, and the third bidirectional threaded rod 113 adjusts the spacing of the high-frequency heater 115 to match the gear thickness, forming a ring heating array. The high-frequency heater 115 is activated to perform non-contact induction heating on the gear. The motor 701 of the clamping mechanism 7 drives the clamping frame 702 to rotate slowly, causing the gear to rotate at a uniform speed, ensuring uniform heating of the gear circumferentially and eliminating thermal stress concentration. The heating temperature and time are controlled by a PLC (Programmable Logic Controller). The controller (programmable logic controller) automatically controls the operation based on the gear material. The operator places the shaft into the V-groove 101 of the pressing frame 10. The hydraulic cylinder 132 drives the limit block 133 to move horizontally, creating a vertical clamping force between the V-groove and the hydraulic limit block 133, thus fixing the shaft. The electric slide rail 121 of the supporting mechanism 12 drives the cylinder 122 to move to one side of the shaft. The cylinder 122 pushes the sleeve 123 above the shaft. The detection mechanism 8 starts, and the industrial camera module 805 scans the spline position on the shaft end face. The PLC compares the angular deviation between the gear keyway and the shaft spline. The motor 701 drives the clamping frame 702 to rotate the gear, aligning their axes. The servo hydraulic cylinder 5 drives the clamping mechanism 7 to descend. The bottom surface of the gear contacts the L-shaped support plate 126. The first bidirectional threaded rod 703 rotates in the opposite direction, and the clamping arc plate 705 retracts inward, disengaging from the gear's inner hole. The servo hydraulic cylinder 5 lifts the clamping frame 702 above the gear, and the arc plate expands back to the upper surface of the gear. While the gear contacts the L-shaped support plate 126, the cylinder 122 drives the L-shaped support plate 126 to fix the gear. The servo hydraulic cylinder 5 drives the mounting plate 6 to press down with a preset pressure and speed, clamping the arc plate 705 to contact the gear end face. The sleeve 123 and the insert rod 124 provide vertical guidance to eliminate the risk of off-center loading. During the pressing process, the industrial camera module 805 of the detection mechanism 8 continuously monitors the axial displacement of the gear. After the pressing is completed, the cylinder 122 releases the limit on the gear.
