Description

Technical Field

[0001] The utility model relates to the technical field of gear grinding, in particular to a gear grinding machine capable of fine-tuning grinding. Background Art

[0002] Gears are widely used, but newly produced gears or gears that have been used for a period of time will have raised edges or tiny gaps in the tooth grooves and cannot be used normally. Therefore, the gears need to be polished. When grinding the gears, the tooth grooves inside the gears need to be polished. The traditional grinding method is to use a grinding wheel machine for manual grinding. This solution is not only easy to cause danger during grinding, but the iron filings generated during grinding will affect the staff's observation of the grinding situation; in addition, the heat generated during grinding will affect the hardness of the gear, which is even more detrimental to the grinding operation.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an embodiment of the utility model provides a gear grinding machine capable of fine-tuning grinding, comprising:

[0034] Shell 1;

[0035] A controller 2, disposed on the outer wall of the housing 1, for controlling the operation of the device;

[0036] A cooling mechanism, disposed on the outer wall of the housing 1, for cooling the gear body 507 when grinding;

[0038] A grinding mechanism, disposed on the top of the fixing mechanism, for grinding the gear body 507;

[0039] A second driving motor 6 is installed inside the housing 1;

[0040] A driving wheel 601 is mounted on top of the second driving motor 6;

[0041] The driving belt 602 is connected between the driving wheel 601 and the fixing mechanism. When in use, the gear body 507 is installed on the fixing mechanism. The second driving motor 6 and the grinding mechanism are started by the controller 2. The second driving motor 6 can drive the gear body 507 to rotate, and the grinding mechanism can grind the tooth grooves of the gear body 507. Heat will be generated during grinding, and the gear body 507 can be cooled by the cooling mechanism. The second driving motor 6 and the second electric push rod 503 can also be controlled by the controller 2 to cooperate with each other during use, so as to achieve fine adjustment of the positions of the gear body 507 and the grinding wheel 506 during the grinding process, so that the gear can be ground more accurately.

[0042] like Figure 1 and Figure 2 As shown, a sealing cover 101 is installed on the top of the housing 1, and a glass 102 is embedded in the side wall of the sealing cover 101. When in use, the sealing cover 101 can prevent iron filings from flying out, and the embedded glass 102 allows the staff to observe the internal situation when in use.

[0043] like Figure 1 and Figure 2 As shown, a hinge 103 is connected between the sealing cover 101 and the housing 1, and a handle 104 is provided on the outer wall of the sealing cover 101. The sealing cover 101 can be opened and closed by the handle 104, and the hinge 103 allows the sealing cover 101 to rotate freely.

[0044] like Figure 2 As shown, a water baffle 105 is provided inside the housing 1, and a movable groove 106 is opened inside the water baffle 105. During cooling, the water baffle 105 can prevent water from contacting the equipment at the bottom, and the movable groove 106 can allow the fixed column 401 to rotate freely inside the water baffle 105.

[0045] like Figure 3As shown, the cooling mechanism includes a water tank 3 arranged on the outer wall of the shell 1, a water pump 301 installed inside the water tank 3, a plug 306 installed at the water inlet end of the water tank 3, a water outlet pipe 302 arranged at the water outlet end of the water pump 301, and a nozzle 303 arranged at the water outlet end of the water outlet pipe 302. The nozzle 303 is located inside the shell 1. When in use, tap water is introduced into the water tank 3, and then the plug 306 is installed on the water inlet. When cooling is required, the water pump 301 is turned on to pump water in the water tank 3 into the water outlet pipe 302, and then sprayed out from the nozzle 303 to cool the gear body 507.

[0046] like Figure 3 As shown, a return pipe 304 is installed at the bottom of the water baffle 105, and a filter 305 is installed at the water outlet end of the return pipe 304. The end of the return pipe 304 away from the outer shell 1 is installed inside the water tank 3. After the water mist is sprayed out, the water will fall on the water baffle 105, and then flow into the return pipe 304, filter the iron filings through the filter 305, and then flow back to the inside of the water tank 3.

[0047] like Figure 4 and Figure 5 As shown, the fixing mechanism includes a base 4 installed inside the housing 1, a fixing column 401 arranged on the top of the base 4, a first electric push rod 402 arranged inside the fixing column 401, a conical block 403 installed on the top of the first electric push rod 402, a push block 404 installed inside the fixing column 401, a connecting rod 405 arranged at one end of the push block 404, a fixing block 406 arranged at the end of the connecting rod 405 away from the push block 404, and a spring 407 installed between the fixing column 401 and the push block 404. The fixing column 401 is slidably installed inside the fixing column 401. When in use, the gear body 507 is placed on the disc 5, and the middle hole of the gear body 507 is installed in the disc 5. In the fixed column 401, the first electric push rod 402 is then started to push the conical block 403 to move upward to push the push block 404 outward, and at the same time drive the fixed block 406 to move outward and fit against the inner wall of the center hole of the gear body 507, so as to fix the gear body 507 through the fixed block 406. Since the fixed block 406 is movable, it can fix the gear body 507 of any size. When the gear body 507 needs to be removed, the first electric push rod 402 is retracted to drive the push block 404 to move downward. After the push block 404 has no outward supporting force, it is pushed toward the inside of the fixed column 401 by the spring 407, and the gear body 507 is loosened by driving the fixed block 406 to move.

[0048] Furthermore, the outer wall fixing sleeve of the fixed column 401 is provided with a driven wheel, and the end of the driving belt 602 away from the driving wheel 601 is connected to the driven wheel in a transmission manner. In this way, under the drive of the second driving motor 6, the driving wheel 601 can be driven to rotate, and the driving wheel 601 can then drive the driven wheel to rotate through the driving belt 602, thereby driving the fixed column 401 to rotate, thereby realizing the rotation of the gear body 507.

When grinding is required, the first drive motor 504 is started to drive the grinding wheel 506 to rotate through the drive shaft 505, and then the grinding wheel 506 is driven to move through the second electric push rod 503 to grind the tooth groove of the gear body 507.

[0050] In the embodiment of the utility model, when in use, the gear body 507 is placed on the disc 5, the middle hole of the gear body 507 is installed in the fixing column 401, and then the first electric push rod 402 is started to push the conical block 403 upward to push the push block 404 and the fixing block 406 outward to fit the inner wall of the middle hole of the gear body 507, so that the gear body 507 can be fixed, and then the second drive motor 6 is controlled by the controller 2 to start, and the second drive motor 6 drives the gear body 507 through the drive belt 602. The gear body 507 rotates to move the tooth groove to be polished to the grinding wheel 506, and the second electric push rod 503 is controlled by the controller 2 again. The second electric push rod 503 adjusts the position of the grinding wheel 506 for polishing. The gear body 507 will generate heat during polishing. At this time, the tap water in the water tank 3 is sprayed to the gear body 507 through the outlet pipe 302 to cool it down. The cooled water will be blocked by the water baffle 105 and enter the return pipe 304. The iron filings are filtered out by the filter 305 and then flow back to the inside of the water tank 3.

[0051] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
