Description

Technical Field

[0001] This application relates to the field of gear grinding machines, and in particular to adjustable quick-release mechanisms for gear grinding machines. Background Technology

[0002] A gear grinding machine is a specialized machine tool used to grind gears, racks, and other toothed parts on workpieces. It is commonly used in the manufacture, repair, and maintenance of various gear transmission systems and gearboxes. Gear grinding machines can efficiently produce precise tooth profiles, ensuring accurate gear meshing and transmission efficiency. Gear grinding machines are mechanical devices used to dress and process gears or racks. Their function is to achieve the required precision and quality standards for the tooth surface, tooth profile, and dimensions of gears or racks through grinding, cutting, or other processing methods.

[0003] The utility model patent with announcement number CN220407326U proposes a positioning mechanism for a gear grinding machine, including a gear grinding machine body, a support base, a rotating rod, and a loading plate. The support base is installed on the surface of the gear grinding machine body, and the loading plate is installed in the middle of the support base. The rotating rod, which is rotatably connected to the support base, passes through the end of the loading plate. A fixing rod is fixed in the middle of the loading plate, and a first clearance groove is opened at the end of the fixing rod near the loading plate. Several sets of abutment plates are arranged inside the first clearance groove, and the abutment plates are elastically connected to the fixing rod.

[0004] In one of the gear grinding machine positioning mechanisms described above, when fixing the gear, an operator needs to press the abutment plate to make it enter the first clearance groove, and then put the gear on the fixing rod. By releasing the abutment plate, the abutment plate springs back and abuts against the gear to position and install the gear. However, during long-term work, the operator presses the abutment plate repeatedly, which puts a lot of pressure on the fingers and reduces work efficiency. Utility Model Content

[0005] To address the aforementioned issues, this application provides an adjustable quick-release mechanism for a gear grinding machine.

[0006] The adjustable quick-release mechanism for the gear grinding machine provided in this application adopts the following technical solution:

[0007] An adjustable quick-release mechanism for a gear grinding machine includes a gear grinding machine body. The gear grinding machine body is equipped with a mounting assembly for quick-release gears. The mounting assembly includes a support plate fixedly connected to the top of the gear grinding machine body. A placement plate is provided on the support plate. A moving assembly for moving the placement plate is provided on the support plate. A fixing column is fixedly connected to the upper surface of the placement plate. Multiple annular arrays of first sliding grooves are formed on the upper surface of the placement plate. A first threaded rod is rotatably connected to each of the first sliding grooves. An abutment block is slidably disposed within each of the first sliding grooves. The abutment blocks are threadedly connected to the first threaded rods. Rotating assemblies for simultaneously driving multiple first threaded rods to rotate are provided on the placement plate and the fixing column.

[0008] By adopting the above technical solution, when in use, the gear is sleeved on the fixed column, and the gear is placed on the placement plate. Then, the rotating component drives multiple first threaded rods to rotate simultaneously, causing the abutment blocks to move in the first sliding groove. The abutment blocks abut against the inner wall of the gear, thus positioning and fixing the gear. This avoids the problem of operators repeatedly pressing the abutment plate during long-term work, which puts a lot of pressure on their fingers and reduces work efficiency.

[0009] Preferably, the rotating assembly includes a cavity formed within the placement tray, the cavity being located below the fixed column, a rotating rod being provided at the top of the fixed column, one end of the rotating rod penetrating the fixed column and located within the cavity, the rotating rod being rotatably connected to the fixed column, a first bevel gear being fixedly connected to one end of the rotating rod located within the cavity, a plurality of second bevel gears being provided within the cavity, each of the second bevel gears being fixedly connected to one end of the first threaded rod, and all the second bevel gears meshing with the first bevel gears, the top of the rotating rod being located above the fixed column and fixedly connected to a turntable.

[0010] By adopting the above technical solution, by rotating the turntable, the rotating rod drives the first bevel gear to rotate, and the first bevel gear drives multiple second bevel gears to rotate synchronously, so that multiple first threaded rods can rotate at the same time.

[0011] Preferably, a threaded sleeve is fitted on the fixed column, the threaded sleeve is threadedly connected to the fixed column, and a pressure ring for pressing the gear is fixedly connected to the bottom end of the side wall of the threaded sleeve.

[0012] By adopting the above technical solution, after fixing the gear on the placement plate, the threaded sleeve is threaded onto the fixed column, and then the threaded sleeve is rotated to make the pressure ring move downwards to press the gear, which can improve the stability of the gear and prevent the gear from moving up and down.

[0013] Preferably, the moving component includes a second slide groove formed on the upper surface of the support plate, a second threaded rod rotatably connected in the second slide groove, a slider threadedly connected to the second threaded rod slidably in the second slide groove, the top end of the slider being fixedly connected to the placement plate, and a motor for driving the second threaded rod to rotate being fixedly connected to one end of the support plate.

[0014] By adopting the above technical solution, the second threaded rod can be rotated by starting the motor, which can make the slider move in the second slide groove. The position of the placement plate can be adjusted according to the different sizes of gears, and the gears can be ground.

[0015] Preferably, the sidewall of the fixed column is provided with a plurality of annular array receiving grooves, which are respectively located on one side of the abutment block and adapted to the abutment block.

[0016] By adopting the above technical solution, the receiving groove can hide the abutment block, preventing the abutment block from obstructing the insertion of gears of the same size as the fixed column, making it difficult to fit the gears onto the fixed column.

[0017] Preferably, each of the first grooves is fixedly connected with a first guide rod, and the abutment blocks are respectively sleeved on the first guide rods and form a sliding arrangement.

[0018] By adopting the above technical solution, the stability of the abutment block during movement can be improved by the first guide rod, preventing the abutment block from shaking in the first slide groove.

[0019] Preferably, a second guide rod is fixedly connected inside the second groove, and the slider is sleeved on the second guide rod to form a sliding arrangement.

[0020] By adopting the above technical solution, the stability of the slider when moving in the second groove can be improved by the second guide rod, and the slider can be prevented from shaking.

[0021] Preferably, rubber pads are fixedly connected to the sidewalls of the abutment block away from the fixed column.

[0022] By adopting the above technical solution, the rubber pad can prevent collisions when the contact block comes into contact with the gear.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes the cooperative arrangement of structures such as the first sliding groove, the first threaded rod, and the abutment block. In use, the gear is sleeved on the fixed column, and the gear is placed on the placement plate. Then, the rotating assembly drives multiple first threaded rods to rotate simultaneously, causing the abutment block to move within the first sliding groove. The abutment block abuts against the inner wall of the gear, thus positioning and fixing the gear. This minimizes the problem of reduced work efficiency caused by operators repeatedly pressing the abutment plate during long-term work, which puts significant pressure on their fingers.

[0025] 2. By starting the motor to drive the second threaded rod to rotate, the slider can move within the second groove. The position of the placement plate can be adjusted according to different sizes of gears, and the gears can be ground. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses an adjustable quick-assembly mechanism for a gear grinding machine.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The adjustable quick-release mechanism for a gear grinding machine includes a gear grinding machine body 1. The gear grinding machine body 1 is provided with an installation component for quick-release gears. The installation component includes a support plate 2, a placement plate 3, a fixing column 4, a first sliding groove 5, a first threaded rod 6, and an abutment block 7.

[0034] The support plate 2 is fixedly connected to the top of the gear grinding machine body 1. The placement plate 3 is set on the upper surface of the support plate 2. The support plate 2 is provided with a moving component for driving the placement plate 3 to move. The fixed column 4 is fixedly connected to the upper surface of the placement plate 3. Multiple first sliding grooves 5 are provided, all of which are opened on the upper surface of the placement plate 3 and form a ring array. Multiple first threaded rods 6 are provided and are rotatably connected in the first sliding grooves 5 respectively. Multiple abutment blocks 7 are provided and are slidably set in the first sliding grooves 5 respectively. The abutment blocks 7 are threadedly connected to the first threaded rods 6 respectively. The placement plate 3 and the fixed column 4 are provided with a rotating component for simultaneously driving multiple first threaded rods 6 to rotate.

[0035] Reference Figure 2 and Figure 3 The rotating assembly includes a cavity 8 formed within the placement plate 3, located below the fixed column 4. A rotating rod 9 is provided at the top of the fixed column 4, with one end of the rotating rod 9 passing through the fixed column 4 and located within the cavity 8. The rotating rod 9 is rotatably connected to the fixed column 4. A first bevel gear 10 is fixedly connected to one end of the rotating rod 9 within the cavity 8. Multiple second bevel gears 11 are provided within the cavity 8, and each of the second bevel gears 11 is fixedly connected to one end of a first threaded rod 6. All second bevel gears 11 mesh with the first bevel gears 10. A turntable 12 is fixedly connected to the top of the rotating rod 9 above the fixed column 4. By rotating the turntable 12, the rotating rod 9 drives the first bevel gear 10 to rotate, which in turn drives the multiple second bevel gears 11 to rotate synchronously, thus causing the multiple first threaded rods 6 to rotate simultaneously.

[0036] Reference Figure 2 A threaded sleeve 13 is fitted on the fixed column 4 and is threadedly connected to the fixed column 4. A pressure ring 14 for pressing the gear is fixedly connected to the bottom end of the side wall of the threaded sleeve 13. After the gear is fixed on the placement plate 3, the threaded sleeve 13 is threadedly connected to the fixed column 4, and then the threaded sleeve 13 is rotated to make the pressure ring 14 move downward to press the gear, which can improve the stability of the gear and prevent the gear from moving up and down.

[0037] Reference Figure 1 and Figure 2 The moving component includes a second slide groove 15 formed on the upper surface of the support plate 2. A second threaded rod 16 is rotatably connected in the second slide groove 15. A slider 17, which is threadedly connected to the second threaded rod 16, is slidably disposed in the second slide groove 15. The top end of the slider 17 is fixedly connected to the placement plate 3. A motor 18 for driving the second threaded rod 16 to rotate is fixedly connected to one end of the support plate 2. By starting the motor 18 to drive the second threaded rod 16 to rotate, the slider 17 can move in the second slide groove 15. The position of the placement plate 3 can be adjusted according to different sized gears to grind the gears.

[0038] Reference Figure 3 and Figure 4 The side wall of the fixed column 4 is provided with multiple annular array of receiving slots 19. The receiving slots 19 are located on one side of the abutting block 7 and are adapted to the abutting block 7. The abutting block 7 can be hidden by the receiving slots 19 to prevent the abutting block 7 from blocking the gear when it is inserted into the fixed column 4, making it difficult to put the gear on the fixed column 4.

[0039] Reference Figure 2 and Figure 3 Each of the first sliding grooves 5 is fixedly connected with a first guide rod 20, and the abutment blocks 7 are respectively sleeved on the first guide rod 20 and form a sliding arrangement. The first guide rod 20 can improve the stability of the abutment blocks 7 when moving and prevent the abutment blocks 7 from shaking in the first sliding groove 5.

[0040] Reference Figure 2 A second guide rod 21 is fixedly connected inside the second slide groove 15. The slider 17 is sleeved on the second guide rod 21 and forms a sliding arrangement. The second guide rod 21 can improve the stability of the slider 17 when it moves in the second slide groove 15 and prevent the slider 17 from shaking.

[0041] Reference Figure 4 Rubber pads 22 are fixedly connected to the side wall of the abutment block 7 away from the fixed column 4. The rubber pads 22 can prevent the abutment block 7 from bumping into the gear when it comes into contact with it.

[0042] The implementation principle of the adjustable quick-assembly mechanism of the gear grinding machine in this application embodiment is as follows: In use, the gear is sleeved on the fixed column 4 and placed on the placement plate 3. Then, by rotating the turntable 12, the rotating rod 9 drives the first bevel gear 10 to rotate, which in turn drives multiple second bevel gears 11 to rotate synchronously. This causes multiple first threaded rods 6 to rotate simultaneously, driving the abutment block 7 to move within the first sliding groove 5. The abutment block 7 abuts against the inner wall of the gear, thus positioning and fixing the gear. After fixing the gear on the placement plate 3, the threaded sleeve 13 is threaded onto the fixed column 4. Then, by rotating the threaded sleeve 13, the pressure ring 14 moves downward to press the gear, which can improve the stability of the gear and prevent the gear from moving up and down. This minimizes the problem of reduced work efficiency caused by operators repeatedly pressing the abutment plate during long-term work due to excessive finger pressure.

[0043] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
