Description

Technical Field

[0001] The present invention relates to the technical field of parts processing, and more specifically, to a combined machine tool and method for processing large-scale mechanical parts. Background Art

[0002] A reducer is a mechanical transmission device that is mainly used to reduce the speed of the input shaft and increase the torque of the output shaft. It is widely used in many fields such as construction, mining, port loading and unloading, metallurgy, petrochemicals, and electricity. In large-scale mechanical equipment that needs to bear heavy loads and provide high torque, it is often necessary to use an adapted large reducer. The use of large reducers ensures that these equipment can run smoothly at low speeds while providing sufficient power to complete tasks such as excavation, carrying heavy objects, mixing materials, etc.

[0003] The main function of the end cover of a large reducer is to fix and support the internal shaft system components, while preventing lubricating oil leakage and external impurities from entering the reducer. In order to improve the sealing performance of the end cover, a skeleton oil seal needs to be installed in the mounting hole of the end cover. The skeleton oil seal can withstand high temperature and high pressure and has a long service life. When assembling the skeleton oil seal in the end cover in the prior art, the staff puts the skeleton oil seal on the end cover, and then drives the output end of the pressure equipment to apply downward pressure to the skeleton oil seal, and presses the skeleton oil seal into the mounting hole of the end cover.

[0004] However, when placing the oil seal on the end cover, manual placement will inevitably result in errors, and it is impossible to ensure that the oil seal is set concentrically with the mounting hole. Pressing down the oil seal during installation will cause the oil seal to be eccentric and seal poorly, which will cause lubricating oil leakage or intrusion of foreign matter, aggravate the wear of mechanical parts, and cause failures such as jamming, affecting the normal operation of the equipment. Summary of the invention

DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] Refer to the instruction manual Figures 1 to 4 A combined machine tool for processing large mechanical parts is used for concentrically processing an oil seal b and an end cover a, comprising a processing table 1, a processing station 2 is arranged on the processing table 1, the processing station 2 comprises a support seat 22, an end cover a is placed on the support seat 22, a vertically arranged mounting hole is opened on the end cover a, and an oil seal b is placed on the mounting hole of the end cover a;

[0040] An assembly mechanism 3 is provided on the processing table 1, and the assembly mechanism 3 includes a linear drive 2 31, and the linear drive 2 31 is fixedly provided on the processing table 1, and a lower pressing seat 32 is fixedly provided on the output shaft of the linear drive 2 31, and a deviation correction seat 33 is slidably provided on the lower pressing seat 32, and the deviation correction seat 33 includes a connecting plate, and a plurality of adjustment seats are fixedly provided at the bottom of the connecting plate, and the plurality of adjustment seats are all tiltedly provided at the bottom of the connecting plate, and the angles between the plurality of adjustment seats and the connecting plate are the same;

[0041] The oil seal b is located between multiple adjustment seats, and the multiple adjustment seats synchronously descend to touch and adjust the position of the oil seal on the end cover so that the oil seal is concentrically arranged with the mounting hole. The bottom end of the lower pressure seat 32 pushes the oil seal b downward to assemble the oil seal b into the end cover a.

[0042] It should be noted that oil seal b is a skeleton oil seal, which is composed of an internal skeleton, rubber and spring. End cover a is used to support the drive shaft of the reducer to ensure the stability and straightness of the shaft and reduce the swing and vibration of the shaft. In order to further ensure that the drive shaft can operate stably and reliably, the length of end cover a is set longer, that is, the length of the mounting hole opened on the end cover a is longer.

[0043] It should also be noted that the linear drive 2 31 is configured as a hydraulic cylinder, which is fixedly disposed on the processing table 1, and the lower pressing seat 32 is fixedly disposed on the output shaft of the hydraulic cylinder. The connecting plate is slidably disposed on the lower pressing seat 32. The top ends of the multiple adjustment seats are arranged in sequence along the vertical axis of the lower pressing seat 32, and the bottom ends of the adjustment seats are inclined outward to form an angle with the connecting plate, and the angles between the multiple adjustment seats and the connecting plate are the same.

[0044] The specific implementation scenario is as follows: the support seat 22 is located directly below the lower pressure seat 32, the end cover a is placed on the top of the support seat 22, and then the oil seal b is placed on the end cover a, so that the oil seal b is located on the mounting hole of the end cover a, and the linear drive 2 31 is started. The output shaft of the linear drive 2 31 drives the lower pressure seat 32 to move downward. When the bottom end of the lower pressure seat 32 is close to the top of the oil seal b, the deviation correction seat 33 is driven to descend vertically. The oil seal b is located between multiple adjustment seats. If the mounting holes of the oil seal b and the end cover a are not concentric, the deviation correction seat 33 is driven to descend vertically. During the descending process of the deflection seat 33, the inclined side wall of the adjusting seat will push the oil seal b to move. As the deviation correction seat 33 continues to descend, the inclined side walls of multiple adjusting seats are in contact with the oil seal b. At this time, the adjusting seat completes the position adjustment of the oil seal b. The mounting hole of the oil seal b and the end cover a are concentrically arranged. Then the deviation correction seat 33 is driven to move upward, and finally the lower pressure seat 32 is driven downward by the output shaft of the linear drive 2 31. The downward pressure is applied to the oil seal b through the bottom end of the lower pressure seat 32, and the oil seal b is assembled into the mounting hole of the end cover a.

[0045] Refer to the instruction manual Figures 1 to 4 In order to improve the processing efficiency, after the oil seal b is installed in the end cover a, another oil seal b can be processed quickly. After the oil seal b is placed on the end cover a before assembly, since the end cover a is provided with a mounting hole, if the oil seal b partially tilts into the mounting hole during the adjustment process, it will cause a large deviation during adjustment. Specifically, the processing station 2 includes a turntable 21, a support seat 22 is fixedly arranged on the turntable 21, a linear drive 1 24 is fixedly arranged in the support seat 22, and an auxiliary plate 25 is fixedly arranged on the output shaft of the linear drive 1 24, and the auxiliary plate 25 is adapted to the mounting hole of the end cover. A rotary drive 3 is fixedly arranged in the support seat 22, and a positioning seat 23 is fixedly arranged on the output shaft of the rotary drive 3, and the positioning seat 23 is used to position the end cover.

[0046] It should be noted that the linear drive 1 24 is configured as a cylinder, and the auxiliary plate 25 is fixedly arranged on the output shaft of the cylinder. The rotary drive 3 is configured as a motor, and the positioning seat 23 is fixedly arranged on the output shaft of the motor. A positioning groove is provided on the support seat 22, and the positioning groove is adapted to the end cover a. After the end cover a is placed in the positioning groove, the positioning groove can limit the end cover a in the horizontal direction. The positioning device provided on the support seat 22 is similar to the positioning groove in positioning the end cover a. As a mature prior art, the positioning device will not be described in detail in this application.

[0047] It should also be noted that the end cover a is placed in the positioning groove, the rotating driver 3 is started to drive the positioning seat 23 to rotate, and the positioning seat 23 cooperates with the positioning groove to position the end cover a, and then the linear driver 24 is started, and the movement of the output shaft of the linear driver 24 drives the auxiliary plate 25 to move up, so that the top of the auxiliary plate 25 and the top of the end cover a are at the same horizontal height, that is, the auxiliary plate 25 can cover the mounting hole of the end cover a, and then the oil seal b is placed on the end cover a. In the process of adjusting the oil seal b to be concentric with the mounting hole of the end cover a, part of the oil seal b can be prevented from falling into the mounting hole and tilting. After the concentric setting of the mounting hole of the oil seal b and the end cover a is completed, the bottom end of the lower pressure seat 32 is driven to press the oil seal b, and then the auxiliary plate 25 is driven to move down, and finally the oil seal b is assembled into the end cover a through the lower pressure seat 32, and the effect of combined processing is achieved by reciprocating in this way.

[0048] Refer to the instruction manual Figures 2 to 4 In order to facilitate driving the correcting seat 33 to slide vertically on the lower pressure seat 32, specifically, the assembly mechanism 3 includes a linear driver three 34, an auxiliary seat is fixedly arranged on the output shaft of the linear driver two 31, the lower pressure seat 32 is fixedly arranged at the bottom of the auxiliary seat, the linear driver three 34 is fixedly arranged on the auxiliary seat, and the output shaft of the linear driver three 34 is fixedly arranged on the correcting seat 33.

[0049] It should be noted that the linear drive 34 is configured as a cylinder, and the output shaft of the cylinder is fixedly disposed on the deviation correction seat 33 .

[0050] It should also be noted that when the linear drive three 34 is started, the movement of the output shaft of the linear drive three 34 drives the deviation correction seat 33 to move.

[0051] Refer to the instruction manual Figure 5After multiple support seats 22 are set, the turntable 21 rotates to achieve the effect of multi-station processing. If the oil seal b is still placed manually on the end cover a, it will not only increase the workload of the workers, but also lead to low processing efficiency. Therefore, it is necessary to set a group of mechanisms for automatic feeding, that is, a mechanism for automatically conveying and grabbing the oil seal b. If traditional robotic arms and other components are used to transfer and install the oil seal b, it not only increases the use cost of the equipment, but also due to the limited space between the lower pressure seat 32 and the top of the end cover a, the end effector of the robotic arm will cause interference when moving in the limited space. Therefore, the above problems need to be solved. Specifically, a feeding tray 4 is provided on the processing table 1, and the feeding tray 4 is rotatably arranged on the processing table 1. An end cover is placed on the feeding tray 4. The horizontal height of the feeding tray 4 is higher than the horizontal height of the end cover on the support seat 22, and the feeding tray 4 is adapted to the turntable 21. A transfer mechanism 7 is arranged on the lower pressure seat 32, and the transfer mechanism 7 includes a hollow seat 71. The hollow seat 71 is fixedly arranged at the bottom end of the lower pressure seat 32, and a negative pressure pump is fixedly connected to the hollow seat 71. An assembly seat 72 is fixedly arranged at the bottom of the hollow seat 71, and a plurality of air holes 73 are opened at the bottom of the assembly seat 72. The plurality of air holes 73 are arranged in a ring shape, and the air holes 73 are connected with the inside of the hollow seat 71. The assembly seat 72 is adapted to the oil seal.

[0052] It should be noted that a mounting groove is provided on the feed tray 4, and the oil seal b is placed in the mounting groove. The mounting groove has a limiting effect on the oil seal b, and a positioner can be provided in the mounting groove. The positioner can be positioned according to the oil seal b of different sizes. As a mature prior art, it is not described here. A motor is fixedly provided in the processing table 1, and the output shaft of the motor is fixedly provided with the feed tray 4, and the output shaft of the motor drives the feed tray 4 to rotate horizontally.

[0053] It should also be noted that, referring to Fig. 9 The aperture of the air hole 73 is narrow at the top and wide at the bottom. A layer of cushion is provided at the bottom of the assembly seat 72. When the cushion is attached to the top of the oil seal b, the contact area with the oil seal b can be increased. When the negative pressure pump is started, the narrow-at-top-wide-at-bottom arrangement of the air hole 73 can increase the contact space between the air hole 73 and the top of the oil seal b, thereby enhancing the negative pressure effect. The traditional negative pressure adsorption method is to use a suction cup structure, but if a suction cup is provided at the bottom of the assembly seat 72, due to the wall thickness of the suction cup, the force on the top of the oil seal b will be uneven when the assembly seat 72 is pressed down. Therefore, opening the air hole 73 is a better choice than providing a suction cup.

[0054] In this embodiment, an oil seal b is placed in the installation groove opened on the feed disc 4, and an end cover a is placed in the support seat 22. The turntable 21 drives the support seat 22 to rotate to the position directly below the lower pressure seat 32, and then drives the feed disc 4 to rotate, so that the oil seal b on the feed disc 4 rotates to the position directly below the lower pressure seat 32, and then starts the linear drive 2 31. The output shaft of the linear drive 2 31 drives the lower pressure seat 32 to move downward. When the assembly seat 72 is in contact with the top of the oil seal b, the negative pressure pump is started. The negative pressure pump extracts the air in the hollow seat 71. The pressure in the hollow seat 71 drops to form a negative pressure. The oil seal b is positioned at the bottom of the assembly seat 72 by the negative pressure, and then the linear drive 2 31 is started. Linear driver 2 31, the output shaft of linear driver 2 31 drives the lower pressure seat 32 to move up, and then drives the feed plate 4 to rotate to avoid interference between the feed plate 4 and the turntable 21, and then the output shaft of linear driver 2 31 drives the hollow seat 71 to descend. When the oil seal b is fitted on the end cover a, the negative pressure pump is turned off. Due to the change in gas flow in the hollow seat 71 after the negative pressure pump is turned off, the oil seal b on the end cover a will have a position deviation. To ensure that the mounting hole of the end cover a is concentric with the oil seal b, it is necessary to drive the deviation correction seat 33 to move down to adjust the position of the oil seal b, and then drive the assembly seat 72 to descend to assemble the oil seal b into the mounting hole of the end cover a.

[0055] Different from the above-mentioned implementation mode, in which the negative pressure pump is turned off after the oil seal b is affixed to the end cover a, the negative pressure pump is still in the on state after the oil seal b is affixed to the end cover a. In this way, there is no need to adjust the position of the oil seal b, and the assembly seat 72 is directly driven downward to assemble the oil seal b into the end cover a. Compared with the above-mentioned implementation mode, the step of concentrically adjusting the oil seal b and the mounting hole of the end cover a is saved.

[0056] Refer to the instruction manual Fig. 9 and Fig.10The end cover a of the vertical reducer is longer, that is, the mounting hole is longer. In order to provide double sealing protection, ensure that the lubricating oil inside the reducer will not leak, and prevent external dust and impurities from entering the reducer, thereby improving the reliability of the entire system, two oil seals b will be installed in the end cover a. In order to reduce mutual interference and thus improve the overall reliability and maintenance convenience, a gap is left between the two oil seals b in the end cover a and they are not directly fitted. Therefore, the first installed oil seal b has a longer moving stroke in the end cover a, and the assembly seat 72 pushes the oil seal b to move down for a longer time and the force time is also longer. Since the assembly seat 72 is provided with an air hole 73, the rubber on the top of the oil seal b will be pressed into the air hole 73 during the downward movement of the assembly seat 72. , and if the negative pressure pump is not turned off, when the first oil seal b is installed, the top of the oil seal b is subjected to the synergistic effect of the downward pressure and the suction force, resulting in wear and deformation of the end face of the oil seal b, thereby shortening the service life of the oil seal b. In order to prevent this phenomenon from occurring, specifically, an adjustment plate 74 is slidably arranged in the hollow seat 71, a through hole 741 is opened on the adjustment plate 74, a fixing column 742 is fixedly arranged on the adjustment plate 74, the fixing column 742 is adapted to the air hole 73, an elastic member 75 is arranged between the adjustment plate 74 and the inner wall of the hollow seat 71, a rotation driver 2 76 is fixedly arranged on the connecting plate, a pull wire 77 is wound around and fixedly arranged on the output shaft of the rotation driver 2 76, and the bottom end of the pull wire 77 is fixedly arranged on the adjustment plate 74.

[0057] It should be noted that a rectangular hole is provided on the lower pressure seat 32, and the rotating driver 76 is configured as a motor. A winding wheel is fixedly provided on the output shaft of the motor. The top end of the pull wire 77 is wound and fixedly provided on the winding wheel. The winding wheel is located in the rectangular hole. A sliding rod is fixedly provided on the adjustment plate 74, and the bottom end of the pull wire 77 is fixedly provided on the sliding rod.

[0058] It should also be noted that the elastic member 75 is configured as a spring, the top end of the spring is fixedly disposed on the top inner wall of the hollow seat 71, and the bottom end of the spring is fixedly disposed on the adjustment plate 74. The fixing column 742 is clamped with the air hole 73.

[0059] After the oil seal b is positioned at the cam 72, the cam 72 is in a state of being compressed and the cam 73 is in a state of being compressed.

[0060] Refer to the instruction manual Figure 6 and Figure 7 In order to facilitate driving the turntable 21 to rotate a specified angle so that the multiple support seats 22 can always be located directly below the lower pressure seat 32, specifically, a driving component 5 is provided on the processing table 1, and the driving component 5 includes a rotating driver 51 and a gear box 52. A sprocket 53 is fixedly provided on the output shaft of the rotating driver 51 and the input end of the gear box 52. The two sprockets 53 are connected by the same chain transmission, and the output end of the gear box 52 is fixedly provided with the turntable 21.

[0061] It should be noted that the rotary driver 51 is configured as a motor, the sprocket 53 is fixedly disposed on the output shaft of the motor, and the gear box 52 can change the transmission direction of the drive shaft. As a prior art, no further elaboration is given here.

[0062] It should also be noted that when the rotary driver 51 is started, the output shaft of the rotary driver 51 drives the sprocket 53 to rotate, the sprocket 53 drives the chain to rotate the input end of the gear box 52, and the output end of the gear box 52 drives the turntable 21 to rotate.

[0063] Refer to the instruction manual Figure 1 and Figure 8 After the oil seal b in the end cover a is assembled, in order to facilitate the removal of the end cover a assembled on the support seat 22, reduce the workload of the staff and improve the overall processing efficiency, specifically, a feeding mechanism 6 is arranged on the processing table 1, and the feeding mechanism 6 includes a fixed seat 61, the fixed seat 61 is fixedly arranged on the processing table 1, a movable seat 62 is slidably arranged on the fixed seat 61, a linear drive four 63 is fixedly arranged on the movable seat 62, a pneumatic seat 64 is fixedly arranged on the output shaft of the linear drive four 63, and a clamping claw 65 is slidably arranged on the pneumatic seat 64.

[0064] It should be noted that a cylinder is fixedly arranged on the fixed seat 61, and the output shaft of the cylinder is fixedly arranged on the fixed seat 61.
