Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gear processing, and in particular to a fixed structure for processing reducer gears. Background Technology
[0002] Gears are key components in speed reducers, achieving transmission, speed regulation, and torque amplification through gear meshing. Some speed reducer gears require drilling holes on their end faces during machining. However, since the tooth grooves on their outer circumference have already been machined and require high precision, ordinary clamping structures can easily damage these grooves. Therefore, this invention proposes a fixing structure for speed reducer gear machining that differs from existing technologies to solve the aforementioned technical problems. Utility Model Content
[0003] In order to improve the problem that the tooth groove is easily damaged when the ordinary clamping structure is fixed, the present invention provides a fixing structure for gear machining of reducer gears.
[0004] This utility model provides a fixing structure for machining gears in a speed reducer, adopting the following technical solution:
[0005] A fixing structure for machining reducer gears includes a first plate, a rotating assembly installed at the middle position of the upper surface of the first plate, a second plate installed on the upper surface of the rotating assembly, a plurality of sets of strip holes opened on the second plate, a plurality of sets of locking assemblies penetrating the strip holes installed on the second plate, translation assemblies installed on both sides of the upper surface of the first plate, and pressing assemblies installed at the ends of the two sets of translation assemblies.
[0006] By adopting the above technical solution, the reducer gear to be processed is placed in the middle position on the upper surface of the second plate. Then, the clamping component is activated to hold it in the tooth groove of the reducer gear. The translation component and the pressing component are activated to restrict the position of the reducer gear in the vertical direction. The rotation component is activated to drive the reducer gear to rotate synchronously, which facilitates the drilling process at different positions on the end face of the reducer gear.
[0007] Optionally, the rotating assembly includes a motor frame, which is fixed to the upper surface of the first plate. A servo motor is installed on the lower surface of the inner cavity of the motor frame, and the end of the output shaft of the servo motor is fixed to the lower surface of the second plate.
[0008] By adopting the above technical solution, the servo motor is started to drive the second plate to rotate, which in turn drives the reducer gear to rotate synchronously, making it convenient to perform hole processing at different positions on the end face of the reducer gear.
[0009] Optionally, the locking assembly includes an electric slide rail, which is fixed to the lower surface of the second plate. An electric slider is installed on the outside of the electric slide rail, and a through-hole rod is installed on the upper surface of the electric slider. A wooden wedge is installed on the outside of the through-hole rod.
[0010] By adopting the above technical solution, multiple sets of electric slide rails are activated to drive the electric slider to move horizontally. Under the action of the electric slider, the insertion rod and the wooden wedge block can move synchronously and thus be clamped in the tooth groove of the reducer gear. Under the action of the wooden structure of the wooden wedge block, the tooth groove is not easily damaged.
[0011] Optionally, the translation component includes a frame, which is fixed to the upper surface of the first plate. A cavity is formed inside the top wall of the frame, and a third plate is provided inside the cavity formed in the frame. A second cylinder is installed at the end of the top wall of the frame.
[0012] Optionally, the pressing assembly includes a first cylinder, which is fixed to the upper surface of the third plate. A cylinder frame is fitted around the first cylinder and fixed to the end of the output shaft of the second cylinder. A pressure roller is installed at the end of the output shaft of the first cylinder.
[0013] By adopting the above technical solution, multiple sets of second cylinders are activated to extend and retract, thereby driving the cylinder outer frame to move horizontally. Under the action of the cylinder outer frame, the third plate can be driven to move synchronously to the appropriate position in the inner cavity of the cavity. Then, the first cylinder is activated to extend and drive the pressure roller to move downward until the pressure roller contacts the upper surface of the reducer gear, thereby restricting the position of the reducer gear in the vertical direction.
[0014] Optionally, multiple sets of columns are installed at the outer edge of the lower surface of the second plate, and each set of columns is equipped with a movable wheel at its bottom.
[0015] By adopting the above technical solution, the second plate can drive multiple sets of columns and moving wheels to rotate synchronously on the upper surface of the first plate during the rotation process, thereby further improving the stability of the second plate.
[0016] In summary, this utility model has at least one of the following beneficial effects:
[0017] Place the reducer gear to be processed in the middle position on the upper surface of the second plate. Then, start multiple sets of electric slide rails to drive the electric slider to move horizontally. Under the action of the electric slider, the insert rod and the wooden wedge block can move synchronously and thus clamp in the tooth groove of the reducer gear. Under the action of the wooden structure of the wooden wedge block, the tooth groove is not easily damaged.
[0018] Activating multiple sets of second cylinders allows the cylinder outer frame and third plate to move synchronously. Then, activating the first cylinder extends it, causing the pressure roller to move downwards until it contacts the upper surface of the reducer gear, thereby restricting the position of the reducer gear in the vertical direction.

[0023] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.
[0024] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 An embodiment of this utility model provides a fixing structure for gear processing of a reducer, including a first plate 9, a rotating assembly installed at the middle position of the upper surface of the first plate 9, the rotating assembly including a motor frame 6, the motor frame 6 being fixed at the middle position of the upper surface of the first plate 9, a servo motor 7 being installed at the lower surface of the inner cavity of the motor frame 6, and a second plate 11 being installed at the end of the output shaft of the servo motor 7.
[0025] The gear reducer to be processed is placed in the middle position on the upper surface of the second plate 11. The servo motor 7 is started to drive the second plate 11 to rotate, which can drive the gear reducer to rotate synchronously, making it convenient to perform hole processing at different positions on the end face of the gear reducer.
[0026] Please refer to the attached diagram in the instruction manual. Figure 1 and 2The second plate 11 has multiple sets of strip holes 2 and multiple sets of locking components are installed on the second plate 11. The locking components include an electric slide rail 10, which is fixed to the lower surface of the second plate 11. An electric slider 5 is installed on the outside of the electric slide rail 10. An insertion rod 8 that passes through the strip hole 2 is installed on the upper surface of the electric slider 5. A wooden wedge 1 is installed on the outside of the insertion rod 8. The cross-section of the wooden wedge 1 is set as a triangle.
[0027] The multiple sets of electric slide rails 10 are activated to drive the electric slider 5 to move horizontally. Under the action of the electric slider 5, the insertion rod 8 and the wooden wedge block 1 can move synchronously and be clamped in the tooth groove of the reducer gear. Under the action of the wooden structure of the wooden wedge block 1, the tooth groove is not easily damaged.
[0028] Please refer to the attached diagram in the instruction manual. Figure 1 , 2 3. Translation components are installed on both sides of the upper surface of the first plate 9. The translation components include a frame 12 with an L-shaped longitudinal section. The frame 12 is fixed to the upper surface of the first plate 9. A cavity 13 is opened inside the top wall of the frame 12. A third plate 17 is installed inside the cavity 13 on the frame 12. The cross-section of the third plate 17 is T-shaped. A second cylinder 18 is installed at the end of the top wall of the frame 12.
[0029] Please refer to the attached diagram in the instruction manual. Figure 1 , 2 3. Pressing components are installed at the ends of the two sets of translational components. Each pressing component includes a first cylinder 14, which is fixed to the upper surface of the third plate 17. A cylinder frame 16, fixed to the output shaft end of the second cylinder 18, is fitted around the first cylinder 14. A pressure roller 15 is installed at the end of the output shaft of the first cylinder 14. Activating the extension and retraction of multiple sets of second cylinders 18 can synchronously move the cylinder frame 16 and the third plate 17 to an appropriate position. Then, activating the extension of the first cylinder 14 moves the pressure roller 15 downwards until it contacts the upper surface of the reducer gear, thereby restricting the position of the reducer gear in the vertical direction.
[0030] Please refer to the attached diagram in the instruction manual. Figure 1 Multiple sets of columns 3 are installed on the outer edge of the lower surface of the second plate 11. Each set of columns 3 has a movable wheel 4 mounted at its bottom. The columns 3 and movable wheels 4 are positioned on the outer side of multiple sets of electric slide rails 10, with the bottom wall of the movable wheel 4 contacting the upper surface of the first plate 9. During rotation, the second plate 11 drives the multiple sets of columns 3 and movable wheels 4 to rotate synchronously on the upper surface of the first plate 9, thereby further improving the stability of the second plate 11.
[0031] Working principle: When using the fixed structure for gear processing of this reducer, first place the first plate 9 in an appropriate position, then place the reducer gear to be processed in the middle position on the upper surface of the second plate 11, then start multiple sets of electric slide rails 10 to drive the electric slider 5 to move horizontally. Under the action of the electric slider 5, the insertion rod 8 and the wooden wedge block 1 can move synchronously and thus clamp in the tooth groove of the reducer gear. Under the action of the wooden structure of the wooden wedge block 1, the tooth groove is not easily damaged.
[0032] Once the gear is fixed, multiple sets of second cylinders 18 are activated to extend and retract, thereby driving the cylinder outer frame 16 to move horizontally. Under the action of the cylinder outer frame 16, the third plate 17 can be driven to move synchronously to the appropriate position in the inner cavity of the cavity 13. Then, the first cylinder 14 is activated to extend and drive the pressure roller 15 to move downward until the pressure roller 15 contacts the upper surface of the reducer gear, thereby restricting the position of the reducer gear in the vertical direction.
[0033] The servo motor 7 is started to drive the second plate 11 to rotate, which in turn drives the reducer gear to rotate synchronously. This facilitates the drilling process at different positions on the end face of the reducer gear. During the rotation of the second plate 11, multiple sets of columns 3 and moving wheels 4 can be driven to rotate synchronously on the upper surface of the first plate 9, thereby further improving the stability of the second plate 11.
