Description

Technical Field

[0001] This application relates to the technical field of gear production, and particularly to an auxiliary drilling tooling for trial-produced gear sets. Background Art

[0002] A gear set is a system formed by combining multiple gears. Gear sets are widely used in various machinery and equipment, mainly meeting the needs of various operations by reducing the rotational speed and increasing the torque. The gear set has a simple structure and can work at temperatures as low as -20°C and as high as 70°C, meeting various usage environments. Due to design reasons, some gear sets need to be drilled and pinned during the trial production stage.

[0003] Currently, during the process of drilling and pinning gears, the gear set needs to be placed at a specific position on the machine tool first, and a drilling device is used to perform drilling operations on specific positions of the gear set.

[0004] Regarding the above related technologies, the inventor believes that during the drilling process of the above gear set, in order to ensure the position accuracy of the drilling, the specific position of the gear set needs to be aligned with the corresponding point of the drilling device. Therefore, it is necessary to adjust the specific position of the gear on the machine tool again, which affects the drilling efficiency and quality. Utility Model Content

[0005] In order to improve the processing quality and efficiency of gear sets, this application provides an auxiliary drilling tooling for trial-produced gear sets.

[0006] An auxiliary drilling tooling for trial-produced gear sets provided by this application adopts the following technical solutions:

[0007] An auxiliary drilling tooling for trial-produced gear sets includes a bottom plate, guide bars, a sliding plate, a mounting circular plate, and a limiting plate. Two guide bars are arranged in parallel on the top surface of the bottom plate. The sliding plate is slidably arranged between the two guide bars. The mounting circular plate is connected to the sliding plate. An installation groove is coaxially opened on the top surface of the mounting circular plate. An installation column is coaxially and vertically connected to the inner bottom wall of the installation groove. The limiting plate is arranged on the top surface of the bottom plate and is located between the two guide bars. The limiting plate includes a vertically arranged supporting portion and a butting portion horizontally arranged at the top end of the supporting portion. The vertical portion is arranged on the top surface of the bottom plate. When the sliding plate slides to a certain position, the butting portion abuts against the installation column.

[0008] By adopting the above technical solution, before drilling the gear, the gear is placed in the installation groove of the installation circular plate, and the sliding plate is pushed along the length direction of the guiding strip towards the direction close to the limiting plate until the abutting part of the installation column and the limiting plate abuts together. In this way, the central axis of the gear can be quickly moved to a fixed position each time. Through the mutual cooperation of the bottom plate, the guiding strip, the sliding plate, the installation circular plate and the limiting plate, the precise and rapid alignment of the gear is realized, and the processing quality and efficiency of the gear set are improved.

[0009] Optionally, an anti-disengagement block is arranged on the bottom plate, the anti-disengagement block is arranged between the two guiding strips, and the anti-disengagement block and the limiting plate are respectively arranged at two ends of the length direction of the guiding strip.

[0010] By adopting the above technical solution, the arrangement of the anti-disengagement block avoids the sliding plate disengaging from between the two guiding strips when the sliding plate is moved.

[0011] Optionally, a limiting component is arranged on the bottom plate, the limiting component includes a limiting bottom block and a return spring, a receiving groove is formed on the top surface of the bottom plate, the receiving groove is arranged between the two guiding strips, the distance between the receiving groove and the supporting part is equal to the length of the sliding plate, the limiting bottom block is slidably arranged in the receiving groove, the return spring is arranged in the receiving groove, one end of the return spring is connected to the bottom wall of the receiving groove, and the other end is connected to the limiting bottom block. In the natural state, the top end of the limiting bottom block extends out of the receiving groove under the action of the return spring.

[0012] By adopting the above technical solution, when the sliding plate is pushed to abut against the limiting plate, the sliding plate is clamped between the limiting bottom block and the supporting part. The arrangement of the limiting bottom block realizes the limitation of the sliding plate, and there is no need to manually press the sliding plate against the limiting plate during the drilling process. When it is necessary to withdraw the sliding plate from below the abutting part, the limiting bottom block is pressed into the receiving groove and the sliding plate is moved out.

[0013] Optionally, a contact inclined surface is arranged at the top end of the limiting bottom block, the contact inclined surface is arranged on the side of the limiting bottom block away from the limiting plate, and the lowest position of the contact inclined surface is flush with the top surface of the bottom plate in the natural state.

[0014] By adopting the above technical solution, when the sliding plate is pushed towards the direction close to the limiting plate, the bottom surface of the sliding plate contacts the contact inclined surface, and as the sliding plate is pushed, the limiting bottom block is pressed into the receiving groove. The arrangement of the contact inclined surface facilitates the pushing of the sliding plate.

[0015] Optionally, a sliding groove is formed in the top surface of the mounting circular plate along the radial direction. One end of the sliding groove is communicated with the mounting groove. A positioning wedge block is slidably arranged in the sliding groove, and the end of the positioning wedge block extends into the mounting groove.

[0016] By adopting the above technical solution, after the gear is placed in the mounting groove of the mounting circular plate, the positioning wedge block is moved towards the gear until the positioning wedge block presses against the gear set, reducing the possibility of the gear set rotating in the mounting groove during the stamping of the gear set.

[0017] Optionally, a plurality of mounting grooves are provided on the mounting circular plate. One positioning wedge block is slidably arranged in each sliding groove, and a driving member for driving the positioning wedge block to slide in the sliding groove is arranged on the mounting circular plate.

[0018] By adopting the above technical solution, multiple positioning wedge blocks limit the gear simultaneously, which helps to improve the stability of the gear during the drilling process.

[0019] Optionally, a contact roller is rotatably arranged on the side wall of the sliding plate close to the guiding strip, and the contact roller is in rolling fit with one side of the guiding strip.

[0020] By adopting the above technical solution, the contact roller is in rolling fit with the guiding strip, which helps the sliding plate to slide more smoothly between the two guiding strips.

[0021] Optionally, there are multiple mounting circular plates with different diameter specifications. A plugging bottom plate is connected to the bottom surface of the mounting circular plate, and a plugging frame corresponding to the shape of the plugging bottom plate is connected to the top surface of the sliding plate.

[0022] By adopting the above technical solution, for gears of different specifications, mounting circular plates of different specifications can be installed on the sliding plate, and the plugging bottom plate is inserted into the plugging frame, expanding the application range of the device.

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

Detailed Description of the Embodiment

[0031] The following will Figures 1-3 further describe the present application in detail. An embodiment of the present application provides an auxiliary drilling tool for a trial-produced gear set, which has the effect of improving the processing quality and efficiency of the gear set.

[0032] Referring to Figure 1 , an auxiliary drilling tool for a trial-produced gear set includes a bottom plate 1, guiding strips 2, a sliding plate 3, mounting plates 4, a limiting component 5 and a positioning component 6.

The anti - detachment block 9 includes a butting part 81, a supporting part 82 and a connecting part 83. The connecting part 83 is connected to the top surface of the bottom plate 1, and the supporting part 82 is vertically arranged at the top end of the connecting part 83. The butting part 81 is horizontally arranged at the top end of the supporting part 82. The end of the butting part 81 extends towards the direction close to the sliding plate 3 and is arranged parallel to the guiding strip 2, and the extension direction of the butting part 81 intersects with the central axis of the mounting post 13.

[0035] Refer to Figure 2 , a limiting component 5 is arranged on the bottom plate 1. The limiting component 5 includes a limiting bottom block 51, a connecting lever 52 and a return spring 53. A receiving groove 101 is opened on the top surface of the bottom plate 1. The receiving groove 101 is arranged between two guiding strips 2, and the length direction of the receiving groove 101 is perpendicular to the length direction of the guiding strip 2. The limiting bottom block 51 is slidably arranged in the receiving groove 101, and the return spring 53 is connected between the limiting bottom block 51 and the inner bottom wall of the receiving groove 101. In the natural state, the limiting bottom block 51 extends out of the receiving groove 101 under the action of the return spring 53, and the distance between the limiting bottom block 51 and the supporting block is equal to the length of the sliding plate 3. An abutting inclined surface 511 is arranged on the side of the bottom end of the limiting bottom block 51 away from the limiting plate 8. In the natural state, the lowest point of the abutting inclined surface 511 is flush with the top surface of the bottom plate 1. One end of the limiting bottom block 51 in the length direction is connected with a connecting lever 52. A communicating groove 102 for the connecting lever 52 to pass through is opened on the bottom plate 1. One end of the communicating groove 102 is communicated with the receiving groove 101, and the connecting lever 52 is slidably arranged in the communicating groove 102.

[0036] Refer to Figure 2 and Figure 3, the positioning component 6 is arranged on the mounting circular plate 4. The positioning component 6 includes a rotating ring 61, a positioning wedge 62 and a sliding column 63. A plurality of sliding grooves 42 are equidistantly arranged on the mounting circular plate 4 along the radial direction, and the sliding grooves 42 are communicated with the mounting grooves 41. One positioning wedge 62 is slidably arranged in each sliding groove 42, and the sliding column 63 is connected to the top end of the positioning wedge 62. The rotating ring 61 is rotatably arranged on the top surface of the mounting circular plate 4, and the inner diameter of the rotating ring 61 is equal to the diameter of the mounting groove 41. A driving spiral groove 611 is formed on the bottom surface of the rotating ring 61, and a plurality of sliding columns 63 are simultaneously slidably arranged in the driving spiral groove 611.

[0037] Referring to Figures 1-3 , when drilling the gear set, the gear is sleeved on the mounting column 13 and pushed into the mounting groove 41. The rotating ring 61 is rotated, the sliding column 63 slides in the driving spiral groove 611, and the positioning wedge 62 slides in the sliding groove 42. The positioning wedge 62 extends into the mounting groove 41 and abuts against the peripheral wall of the gear, realizing the positioning of the gear and avoiding the rotation of the gear in the mounting groove 41 during the drilling process. For gears with different diameters, mounting circular plates 4 of different specifications can be selected and installed on the sliding plate 3, expanding the application range of the device.

[0038] Referring to Figure 2 , after the positioning of the gear is completed, the operator pushes the push block 10 to push the sliding plate 3 towards the limiting plate 8. The abutting roller 7 rolls relative to the guiding strip 2, reducing the friction between the sliding plate 3 and the guiding strip 2 and facilitating a smoother sliding process. The bottom surface of the sliding plate 3 contacts the abutting inclined surface 511, pressing the limiting bottom block 51 downward into the receiving groove 101 of the bottom plate 1, and the return spring 53 contracts to accumulate elastic potential energy. One side of the sliding plate 3 abuts against the supporting portion 82, and the mounting column 13 abuts against the end of the abutting portion 81. At this time, the sliding plate 3 moves away from above the receiving groove 101, the return spring 53 extends, and the limiting bottom block 51 pops out under the action of the return spring 53. One side of the limiting bottom block 51 abuts against one side of the sliding plate 3, realizing the limitation of the sliding plate 3.

[0039] Referring to Figure 1 and Figure 2 , the limiting bottom block 51 and the abutting portion 81 quickly limit the position of the gear set, enabling the gear set to move to a specific fixed position each time, improving the drilling accuracy and processing rate. After the drilling operation of the gear is completed, the rotating ring 61 is rotated in the reverse direction, the positioning wedge 62 is separated from the gear, and the position limitation of the gear is released. The connecting lever 52 is pressed downward, the limiting bottom block 51 enters the receiving groove 101, and the sliding plate 3 is pushed away from the limiting plate 8, facilitating the removal of the gear.

[0040] In the embodiment of the present application, the implementation principle of an auxiliary drilling tooling for trial-produced gear sets is as follows: The gear is sleeved on the mounting post 13 and pushed into the mounting groove 41. By rotating the rotating ring 61, the positioning wedge 62 abuts against the circumferential wall of the gear, achieving the positioning of the gear. After the positioning of the gear is completed, the sliding plate 3 is pushed towards the limiting plate 8. The bottom surface of the sliding plate 3 contacts the abutting inclined surface 511, pressing the limiting bottom block 51 downward into the receiving groove 101 of the bottom plate 1. One side of the sliding plate 3 abuts against the supporting portion 82, and the mounting post 13 abuts against the end of the abutting portion 81. At this time, the limiting bottom block 51 pops out under the action of the return spring 53, achieving the limitation of the sliding plate 3. The limiting bottom block 51 and the abutting portion 81 quickly limit the position of the gear set, enabling the gear set to move to a specific fixed position each time, improving the drilling accuracy and processing rate.

[0041] The above are all the preferred embodiments of the present application.
