Description

Technical Field

[0001] The invention relates to the technical field of gear processing, in particular to gear processing equipment adapted to different numbers of teeth. Background Art

[0002] The processing methods of plastic gears mainly include injection molding, CNC machining, cutting and pressing. The most common method is injection molding, which puts the pre-treated plastic particles into the hopper of the injection molding machine. The injection molding machine heats and melts the particles and injects the molten plastic into the gear mold. When the plastic is completely solidified, the mold will open and the gear will be pushed out of the mold using an ejector. In order to make the plastic gear more precise, the gear will be set one circle larger during injection molding. After the injection molded gear is taken out, the plastic gear will be further refined. The processing flow is to use a shaving cutter to mesh with the processed gear, and generate a cutting motion through relative motion, thereby removing the tiny excess on the tooth surface and improving the tooth shape accuracy.

[0003] However, for plastic gears of different sizes and thicknesses, their meshing teeth sizes and shapes are different, and it is difficult to process them by shaving. Shaving is usually suitable for mass production. For small batches or gears of different specifications, its processing efficiency may not be high. In the process of processing such plastic gears, grinding is often used. Grinding can obtain higher processing accuracy and surface quality. Gears with relatively more teeth are not convenient to operate. Based on this, an improvement is proposed, which can process multiple meshing teeth at the same time, and there is no need to change the orientation after clamping, so that different gears can maintain the same accuracy after processing.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8 The present invention provides a technical solution: for plastic gears of different sizes and thicknesses, whose meshing teeth are of different sizes and shapes, and for processing small batches or gears of different specifications, the processing efficiency is low, and a gear processing device suitable for different numbers of teeth is proposed, such as Figure 1 and Figure 2 As shown, it includes a base 1, a servo motor 2 is installed at the lower end of the base 1, and a mounting portion 3 for limiting the gear is installed at the output end of the servo motor 2, and the mounting portion 3 is located at the upper end of the base 1. A plurality of grinding units 6 distributed along the circumference of the base 1 are also installed at the upper end of the base 1. The grinding units 6 are used for gear meshing processing. A hydraulic cylinder 1 9 and a hydraulic cylinder 2 10 are also provided at the upper end of the base 1 for driving the plurality of grinding units 6 to move inside and outside and up and down. The hydraulic cylinder 1 9 and the hydraulic cylinder 2 10 control the feed movement of the grinding unit 6 so that the grinding unit 6 corresponds to the position where the gear body 25 needs to be cut. The hydraulic cylinder 1 9 and the hydraulic cylinder 2 10 are used for control, which can effectively and accurately control.

[0032] like Figure 3As shown, in order to limit the grinding unit 6 and the mounting portion 3, the base 1 includes a lower seat 11 and an upper seat 12, and the lower seat 11 and the upper seat 12 are fixed in an overlapping manner. The upper seat 12 is located at the upper end of the lower seat 11, and the upper seat 12 has a step. A plurality of groups of sliding openings 13 are provided on the upper seat 12, and the sliding openings 13 are distributed along the circumference of the upper seat 12, and the sliding openings 13 coincide with the axis of the upper seat 12. A plurality of groups of grinding units 6 are respectively slidably arranged in a plurality of sliding openings 13, and the supporting layer 22 in the mounting portion 3 is located at the upper end of the upper seat 12. When the blade 64 is cutting, it avoids contact with the upper seat 12, and at the same time, the gear body 25 is completely cut.

[0033] like Figure 6 and Figure 7 As shown, in order to limit the position of the gear body 25, the gear body 25 needs to be rotated so that different positions of the gear body 25 can be processed. The mounting portion 3 includes a rotating shaft 21, a supporting layer 22, an inner interlayer 23 and a fastening cap 24;

[0034] The rotating shaft 21 is fixed to the output end of the servo motor 2, and the rotating shaft 21 extends upward from the upper seat 12. The supporting layer 22 is coaxial with the rotating shaft 21 and the two are fixed. The inner interlayer 23 is sleeved on the rotating shaft 21, and its inner wall is in contact with the outer side of the rotating shaft 21. The inner interlayer 23 is located at the upper end of the supporting layer 22. The outer side of the inner interlayer 23 is sleeved with a gear body 25. The thickness of the gear body 25 is greater than the thickness of the inner interlayer 23, and the inner side of the gear body 25 is in contact with the outer side of the inner interlayer 23, which is used to keep the axis of the gear body 25 coincident with the axis of the rotating shaft 21. The fastening cap 24 is threadedly connected to the rotating shaft 21. The fastening cap 24 is used to squeeze the gear body 25 to clamp the gear body 25. The gear body 25 is clamped between the fastening cap 24 and the supporting layer 22 to limit the gear body 25. The function of the inner interlayer 23 is to be sleeved on the outside of the rotating shaft 21. The inner interlayer 23 can be replaced with different sizes to limit the gear body 25 of different apertures, so that the axis of the gear body 25 coincides with the rotating shaft 21, thereby achieving the positioning function, improving the processing accuracy and enabling faster operation.

[0035] like Figure 4 and Figure 5 As shown, the grinding unit 6 includes an inlay 61 slidably disposed in the sliding opening 13, and a hole corresponding to the sliding opening 13 is penetrated on the lower seat 11 for the falling of debris. The debris generated during the cutting process can fall downward to avoid affecting the sliding of the grinding unit 6;

[0036] The upper end of the inlay 61 is bent, and a sliding shaft 63 passes through the upper end surface of the inlay 61 downward. The sliding shaft 63 can slide up and down along the inlay 61. A blade 64 is detachably fixed to the lower end of the sliding shaft 63. The blade 64 is used to cut the teeth of the gear body 25. The inlay 61 moves horizontally and the sliding shaft 63 moves longitudinally to realize the processing of different gear bodies 25.

[0037] like Figure 4 and Figure 5 As shown, the lower end of the lower seat 11 is provided with a lever plate 62 corresponding to the inlay 61, and a bolt passes through the lever plate 62 from bottom to top. The bolt is threadedly connected to the inlay 61 for controlling the tightness of the inlay 61. By turning the bolt, the tightness of the inlay 61 can be adjusted to prevent the inlay 61 from being too loose and causing the position of the inlay 61 to be offset.

[0038] like Figure 5 As shown, in order to enable the hydraulic cylinder 9 to control the lateral movement of the inlay 61, the following components are provided: a plurality of groups of outer support shafts 4 distributed along the circumference of the upper seat 12 are fixed to the upper end of the upper seat 12, a circle of outer fixed disks 7 are fixed to the upper end of the outer support shafts 4, the hydraulic cylinder 9 and the hydraulic cylinder 2 10 are both fixed on the outer fixed disk 7, a circle of driving disks 5 are provided on the upper end of the upper seat 12, the driving disks 5 are sleeved on the plurality of groups of outer support shafts 4, and the driving disks 5 are coaxial with the upper seat 12, the output end of the hydraulic cylinder 9 is fixed to the driving disk 5, and is used to control the up and down movement of the driving disk 5, a groove 51 corresponding to the inlay 61 is provided on the inner side of the driving disk 5, a control rod 66 is hingedly connected between the groove 51 and the inlay 61, the up and down movement of the driving disk 5 is used to control the inward and outward movement of the grinding unit 6, so that the plurality of groups of inlays 61 move synchronously, and the gear body 25 is processed at multiple angles.

[0039] like Figure 5 As shown, in order to make the sliding shaft 63 perform longitudinal cutting movement, a plurality of groups of inner support shafts 81 evenly distributed in a circumference are installed on the upper end of the upper seat 12, and a driving disk 2 8 is sleeved on the plurality of inner support shafts 81. The driving disk 2 8 is coaxial with the upper seat 12, and a plurality of clamping openings 82 corresponding to the sliding shaft 63 are provided at the lower end of the driving disk 2 8. The clamping openings 82 are perpendicular to the axis of the driving disk 2 8, and the cross section of the clamping openings 82 is "T"-shaped. A clamping layer 65 is fixed on the upper end of the sliding shaft 63, and the clamping layer 65 is slidably arranged in the clamping opening 82. The upper end of the driving disk 2 8 is fixed to the output end of the hydraulic cylinder 2 10. The up and down movement of the driving disk 2 8 is used to control the movement of the sliding shaft 63 and produce a cutting effect. The clamping mouth 82 limits the clamping layer 65 to achieve up and down movement without affecting the lateral movement of the inlay 61. It should be noted that after the inlay 61 moves laterally for a certain distance, the blade 64 can cut the gear body 25, and then drive the sliding shaft 63 to move up and down, so that the hydraulic cylinder 1 9 and the hydraulic cylinder 2 10 move separately to avoid jamming.

[0040] The outer end of the clamping opening 82 extends outwardly from the driving disk 2 8 , and the sliding shaft 63 can move out of the clamping opening 82 outwardly, so that the sliding shaft 63 can be taken out horizontally, and the driving disk 2 8 moves upward, so that the gear body 25 can be placed conveniently.

[0041] like Figure 8As shown, in order to enable the inner support shaft 81 to cancel the cooperation with the driving disk 2 8 and expand the range, the inner support shaft 81 is bent and extended upward, and the inner support shaft 81 is rotatably connected to the upper seat 12. When multiple groups of inner support shafts 81 rotate, the diameter formed will change in size, which is used to place the gear body 25. The inner support shaft 81 is subsequently reset, and the gear body 25 is located at the lower end of the bend of the inner support shaft 81 to prevent the gear body 25 from affecting the cooperation between the driving disk 2 8 and the inner support shaft 81.

[0042] The working principle of the present invention is as follows: the gear body 25 is clamped on the mounting portion 3, and then the hydraulic cylinder 1 9 and the hydraulic cylinder 2 10 drive the grinding unit 6 to move and cut. After the corresponding meshing cutting is completed, the servo motor 2 drives the mounting portion 3 to rotate, and the position of the gear body 25 that needs to be processed is replaced. Based on this, all the meshing teeth of the gear body 25 can be clamped. At the same time, the grinding unit 6 moves inside and outside and cuts up and down to realize the processing of gear bodies 25 of different sizes and thicknesses. In addition, the blade 64 is replaced to realize the processing of meshing teeth of different shapes. The grinding unit 6 can also be processed by grinding. The specific operation is as follows:

[0043] First, operate the installation part 3, open the fastening cap 24, and then select a suitable inner interlayer 23 to cooperate with the gear body 25 and the rotating shaft 21, so that the gear body 25 and the rotating shaft 21 are coaxial, and the fastening cap 24 is tightened to complete the clamping of the gear body 25, which is convenient for clamping. After that, the driving disk 2 8 can move upward under the action of the hydraulic cylinder 2 10, and can be separated from the inner support shaft 81. The inner support shaft 81 rotates to increase the diameter of the circle formed by the multiple groups of inner support shafts 81, so that a larger gear body 25 can be placed. After that, the multiple groups of inner support shafts 81 are reset and cooperate with the driving disk 2 8, and the clamping layer 65 can also move horizontally into the clamping port 82, so that the hydraulic cylinder 2 10 controls the sliding shaft 63 to slide up and down. Based on this, it is convenient to clamp gears of different sizes, and the clamping efficiency is high.

[0044] Secondly, the driving plate 5 is driven up and down by the hydraulic cylinder 9 to push the inlay 61 to move, which can accurately control the blade 64 so that it is located at the required processing position. The multiple groups of grinding units 6 move synchronously and to the same extent, so that the processed gear body 25 has higher precision and more uniform meshing at each position.

[0045] In addition, clamping through the mounting portion 3 only requires one clamping, avoiding multiple clampings, so that the position of the gear body 25 is prevented from being deviated, and the processing is fast and the precision is high.
