Description

Technical Field

[0001] The invention belongs to the technical field of diesel generator production, and in particular relates to a double-station grinder for a diesel generator housing. Background Art

[0002] A diesel generator is a small power generation equipment, which refers to a power machine that uses diesel as fuel and a diesel engine as the prime mover to drive the generator to generate electricity. The complete unit is generally composed of a diesel engine, a generator, a control box, a fuel tank, a storage battery for starting and control, a protective device, an emergency cabinet and other components.

[0003] Among the existing diesel generator casings, there are also some casings that are cast by the casting method. The main process is to melt the metal into liquid, and then pour it into a specified mold. The casting of the casing can be completed after waiting for a certain period of cooling. Compared with other casting methods, it is more convenient. However, when the casing is cast by the casting method, the metal liquid may penetrate into the gap between the mold connections, and there will be protrusions on the surface of the cast casing. Therefore, the casing surface needs to be polished.

[0004] The utility model disclosed in China with patent number CN214642609U discloses a generator housing grinding device, comprising an operating table, a baffle is fixedly installed on one side of the top of the operating table, a side panel is fixedly installed on the top of the operating table, a top panel is fixedly installed on the top of the side panel, the top panel is connected to the operating table through the side panel, a motor is fixedly installed on the top of the top panel, a mounting plate is fixedly installed on one side of the operating table, and a first drive motor is fixedly installed on the top of the mounting plate. The simple and convenient generator grinding device can facilitate grinding by mechanical operation, reduce labor load, and improve work efficiency. After the grinding block is damaged after long-term grinding, it can be replaced in time without replacing the entire motor grinding device, reducing the cost of repair when the grinder is damaged, and no manual hand-held fixation is required, which not only ensures the quality of grinding, but also ensures that manual labor away from the grinding device will not be infected due to dust absorption.

[0005] However, in the process of polishing the shell, the existing patent can only polish one side of the shell, and the polishing range is limited, resulting in low practicality. In addition, after the polishing is completed, the staff needs to manually pick it up.

[0035] The present invention will be further described below in conjunction with the embodiments.

[0036] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0037] See also Figure 1-11 The present invention provides a double-station grinder for a diesel generator casing, comprising a processing table 1, wherein processing grooves 2 are symmetrically opened on the top of the processing table 1, and generator casings 12 are arranged inside the two processing grooves 2, and a support ring 3 is fixedly connected to the inside of the processing groove 2 on one side, and a grinding structure 1 for the outer surface of the generator casing 12 is installed below the support ring 3, and a driving gear 7 is rotatably connected to the inside of the processing groove 2 on the other side, and a grinding structure 2 for the inner surface of the generator casing 12 is installed on the top of the driving gear 7, and the top of the processing table 1 is located between the two processing grooves 2 and fixedly connected to a support rod 9, and a rotating structure for the generator casing 12 is installed on the top of the support rod 9.

[0038] Specifically, Figure 1 , Figure 2 and Fig. 9 As shown, the grinding structure 1 includes a transmission disc 1 31 rotatably mounted inside the support ring 3, a tooth groove 32 is provided at the bottom of the transmission disc 1 31, a grinding roller 1 33 is rotatably mounted in a ring array at the bottom of the support ring 3, a transmission gear 1 34 is fixedly connected to the upper part of the side surface of the grinding roller 1 33, and a driving motor 1 35 is fixedly mounted on the top of the processing table 1;

[0040] During the rotation of the transmission end of the driving motor 35, the transmission disc 31 is driven to rotate through the transmission belt. During the rotation, since the transmission disc 31 is meshed with the transmission gear 34 through the tooth groove 32, each grinding roller 33 can be driven to rotate synchronously. Then, the grinding roller 33 can grind the outer surface of the generator housing 12 during the rotation, thereby improving the smoothness and aesthetics of the exterior of the generator housing 12, making it convenient for the staff to carry out the next step of the generator production operation.

[0041] Specifically, Figure 8 and Fig.10 As shown, the second grinding structure includes a fixed plate 71 installed on the top of the driving gear 7, and the interior of the fixed plate 71 is rotatably installed with a second grinding roller 72 in a ring array, and the lower part of the side surface of the second grinding roller 72 is fixedly connected to a second transmission gear 73, and the bottom of the driving gear 7 is fixedly connected to a second transmission plate 74, and the interior of the processing table 1 is fixedly connected to a second driving motor 75, and the fixed plate 71 is fixedly connected to the interior of the second ash discharge pipe 8;

[0042] The second grinding roller 72 is meshed and connected with the driving gear 7 through the second transmission gear 73, and the transmission end of the second driving motor 75 is connected with the second transmission disc 74 through a transmission belt transmission;

[0043] During the rotation of the transmission end of the driving motor 2 75, the transmission belt is used to drive the transmission disc 2 74 to rotate synchronously. After that, the transmission gear 2 73 on the side surface of the grinding roller 2 72 is meshed with the driving gear 7, so that the driving gear 7 can drive the grinding roller 2 72 to rotate during the rotation. The grinding roller 2 72 can grind the inner surface of the generator housing 12 during the rotation, thereby improving the regularity and aesthetics of the inner surface of the generator housing 12, improving the safety and stability of the generator during operation, and at the same time can greatly improve the work efficiency of the staff, thereby greatly improving productivity.

[0044] Specifically, Figure 4 , Figure 5 and Fig.11As shown, the rotating structure includes a chuck 91 rotatably mounted on the top of the support rod 9, the bottom of the chuck 91 is fixedly connected to the transmission shaft of the servo motor, and a ball 92 is rotatably mounted on the top of the support rod 9 and located on the outside of the chuck 91 in a ring array, and a support plate 93 is rotatably connected to the top of the support rod 9, and a collar 94 is fixedly connected to the bottom of the support plate 93, and a fixed groove 95 is provided on the top of the collar 94. During the installation process, the support plate 93 is sleeved on the top of the support rod 9, so that the fixed groove 95 inside the collar 94 is meshed and connected with the chuck 91, and the bottom of the collar 94 is supported on the top of the ball 92, so that the servo motor transmission shaft drives the support plate 93 to rotate during the rotation process; the installation of the servo motor can perform 90° rotation multiple times;

[0045] The two sides of the bottom of the support plate 93 are fixedly connected with push rods 10 in a left-right symmetrical manner, and the push end of the push rod 10 is installed with a fixing structure for the generator housing 12;

[0046] The fixing structure includes a block 101 fixedly mounted at the bottom of the pushing end of the pushing rod 10, a T-shaped slot 102 is provided inside the block 101, a ball bearing 103 is rotatably mounted at the bottom of the block 101 in a bilaterally symmetrical manner, and the T-shaped slot 102 is adapted to the top of the generator housing 12;

[0047] When the support plate 93 is about to rotate to above the processing groove 2, the push rod 10 will start, and its lifting end will be able to drive the block 101 to descend. When it descends to a certain distance, the support plate 93 also successfully rotates the push rod 10 on one side to above the processing groove 2, and the block 101 will be sleeved on the generator housing 12 through the T-shaped slot 102 due to the rotation to limit the generator housing 12, and during the limiting process, the ball 103 will be against the generator housing 12, so that the generator housing 12 can rotate normally, and then the push rod 10 on one side continues to descend, and drives the generator housing 12 to descend.

[0048] Specifically, Figure 6 and Figure 7 As shown, a lifting structure for the generator housing 12 is installed on the top of the support platform 4, and the lifting structure includes an auxiliary pipe 41 fixedly connected to the top of the support platform 4, and the side surface of the auxiliary pipe 41 is provided with lifting grooves 42 in a circular array, and the lifting grooves 42 are arc-shaped, and a spiral spring 43 is fixedly connected inside the auxiliary pipe 41, and a support shell 44 is movably sleeved on the upper part of the auxiliary pipe 41, and the support shell 44 is located below the support ring 3, and a sliding block 45 is fixedly connected inside the support shell 44, and a step slot 46 is provided on the top of the support shell 44;

[0049] The top of the coil spring 43 is rotatably connected to the top of the support shell 44, the sliding block 45 is slidably connected to the lifting slot 42, the bottom of the support platform 4 is fixedly connected to a dust discharge pipe 5, the side surface of the auxiliary pipe 41 is provided with dust discharge slots 6 in a circular array, and the other end of the dust discharge pipe 5 is connected to an external exhaust fan, so that the dust inside the processing tank 2 is discharged through the exhaust fan;

[0050] When the push rod 10 pushes the generator housing 12 down, since the lifting groove 42 is arc-shaped, the support shell 44 will rotate when the sliding block 45 slides inside the lifting groove 42, and the generator housing 12 will be driven to rotate during the rotation process, so that the generator housing 12 can be rotated and adjusted while being processed, thereby increasing the area and range of grinding.

[0051] Specifically, Figure 1 and Figure 2 As shown, the front of the processing table 1 is fixedly connected to the auxiliary table 11, and a discharge structure for the generator housing 12 is installed on the top of the auxiliary table 11. The discharge structure includes a conveying trough 111 opened on the top of the auxiliary table 11, and a conveying roller 112 is rotatably connected inside the conveying trough 111. Baffles 113 are fixedly connected on both sides of the conveying trough 111 and located on the top of the conveying trough 111, and the left baffle 113 is higher than the right baffle 113;

[0052] After the generator housing 12 is polished, the generator housing 12 will first be separated from the inside of the processing groove 2 on the right due to the extension and retraction of the push rod 10, and then during the rotation of the support plate 93, the push rod 10 will drive the generator housing 12 to extend, and then due to the obstruction of the baffle 113, the generator housing 12 will be separated from the inside of the block 101, causing the generator housing 12 to fall and be transported to the next step through the conveying roller 112.

[0053] Specifically, Figure 8 As shown, the bottom of the driving gear 7 is fixedly connected to a dust discharge pipe 8, which runs through the interior of the transmission plate 74, and the other end of the dust discharge pipe 8 is connected to another exhaust fan, so that the exhaust fan can discharge the dust inside the processing tank 2 during the exhaust process.

[0054] Working principle and use process of the present invention: During use, the staff first puts the generator housing 12 to be polished into the left processing groove 2, so that the generator housing 12 is covered above the support shell 44;

[0055] Then, the servo motor is started to drive the chuck 91 to rotate, so that the support plate 93 rotates 90 degrees, and the push rod 10 is synchronously lowered during the rotation of the support plate 93, so that the structure on the top of the generator housing 12 successfully enters the interior of the T-shaped slot 102, and then the push rod 10 drives the generator housing 12 to move up and down;

[0056] Since the generator housing 12 is covered on the top of the support housing 44, it will synchronously drive the support housing 44 to move up and down in the process of moving up and down. Since the lifting groove 42 is arc-shaped, the support housing 44 will also rotate during the process of moving up and down, thereby driving the generator housing 12 to rotate; at this time, the drive motor 35 can be started, and the transmission end of the drive motor 35 drives the transmission disc 31 to rotate through the transmission belt during the rotation process. During the rotation process, since the transmission disc 31 is meshed and connected with the transmission gear 34 through the tooth groove 32, it can synchronously drive each grinding roller 33 to rotate, and then the grinding roller 33 can grind the outer surface of the generator housing 12 during the rotation process;

[0057] After the outer surface is polished, the push rod 10 is started to recover, so that the generator housing 12 leaves the left processing groove 2, and then the support plate 93 is rotated 90 degrees twice, so that the generator housing 12 is located above the right processing groove 2 and enters the right processing groove 2;

[0058] Then the drive motor 2 75 can be started. During the rotation of the drive end of the drive motor 2 75, the drive disc 2 74 is driven by the drive belt, and then the drive gear 2 73 on the side surface of the grinding roller 2 72 is meshed with the drive gear 7, so that the drive gear 7 can drive the grinding roller 2 72 to rotate during the rotation, and the grinding roller 2 72 can grind the inner surface of the generator housing 12 during the rotation.

[0059] After the inner surface of the generator housing 12 is polished, the push rod 10 is retracted to drive the generator housing 12 to rise, so that the generator housing 12 leaves the right processing groove 2, and then the support plate 93 rotates 90° again, and the push rod 10 slowly descends during the rotation. When the support plate 93 successfully completes the 90° rotation, the generator housing 12 connected to the push rod 10 is also located above the conveying groove 111 at the same time, and then the support plate 93 rotates 90° again, and this time the generator housing 12 is blocked by the baffle 113, so that the generator housing 12 will fall on the conveying roller 112, and then the generator housing 12 is moved to the next production step through the transmission of the conveying roller 112.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
