Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of engineering elements, and particularly relates to a transmission device, in particular to a planetary gear press-fitting equipment and a working method. BACKGROUND

[0002] In the production process of an electronic brake, the installation of a planetary gear set is an important link. Since a planetary gear has multiple planetary gears, a plurality of vacuum suction devices are required to be used to grab and install the planetary gears. In the related art, a guide groove constraint type motion conversion mechanism is used to realize the simultaneous movement of the plurality of vacuum suction devices through the driving of a rotating shaft, so as to avoid the position deviation of the corresponding vacuum suction device caused by the signal deviation of the traditional independent driving of multiple motors.

[0003] The principle of the guide groove constraint type motion conversion mechanism is to drive the sliding shaft to move along the guide groove through the rotation of the driving shaft, that is, to convert the rotary motion into linear motion. This causes the sliding shaft to impact the inner wall of the guide groove when the driving shaft is started. The reason for the above problem is that in order to ensure smooth translation, the groove width of the guide groove needs to be greater than the diameter of the sliding shaft. When the sliding shaft is pushed to move by the spiral groove on the driving shaft, the sliding shaft needs to move downward first, and then the subsequent translation can be performed after the sliding shaft is tightly abutted with the inner wall of the guide groove. As a result, the sliding shaft will impact the fixed position of the inner wall of the guide groove every time it is started, causing an impact indentation at the position.

[0004] Therefore, when the driving shaft rotates, the sliding shaft cannot slide at the first time due to the impact indentation of the groove body in the guide groove constraint type motion conversion mechanism, but first rotates with the driving shaft by a certain angle before performing linear motion again. This will cause an error in the linear motion.

[0005] Therefore, it is necessary to design a new planetary gear press-fitting equipment and a working method.

[0006] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background of the present application, and therefore, the above description is not considered to constitute prior art information. SUMMARY

[0061] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0062] As used herein, the phrases "in one embodiment", "according to one embodiment", "in some embodiments", and the like are generally intended to refer to the fact that a described feature, structure, or characteristic can be included in at least one embodiment of the disclosure. Thus, features, structures, or characteristics can be included in more than one embodiment of the disclosure, and this phrasing is not necessarily intended to refer to the same embodiment. As used herein, the terms "for example," "e.g.," "for instance," and the like are used to indicate one or more examples, instances, or illustrations. Any implementation, aspect or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects or designs. Rather, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0063] The principle of the guide slot constraint motion conversion mechanism is to drive the sliding shaft 32 to move along the guide slot by the rotating action of the drive shaft 13, that is, to convert the rotary motion into linear motion, which causes the sliding shaft 32 to impact the inner wall of the guide slot when the drive shaft 13 is started. The reason for the above problem is that in order to ensure smooth translation, the slot width of the guide slot needs to be greater than the diameter of the sliding shaft 32, and when the sliding shaft 32 is pushed to move by the spiral groove on the drive shaft 13, the sliding shaft 32 must first move downward, and only after the sliding shaft 32 is tightly abutted with the inner wall of the guide slot can subsequent translation be carried out. Over time, this will cause the sliding shaft 32 to impact the fixed position of the inner wall of the guide slot every time it is started, resulting in an impact indentation at this position.

[0064] Therefore, when the guide slot constraint motion conversion mechanism has an impact indentation in the slot body, that is, when the drive shaft 13 rotates, the sliding shaft 32 cannot slide in the first time, but will first rotate with the drive shaft 13 for a certain angle before performing linear motion again after abutting with the straight slot, which will cause errors in linear motion.

[0065] The above-mentioned defects are the results of the inventors' practice and careful research, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to solve the above-mentioned problems should be the contributions of the inventors to the present disclosure.

[0066] It should be noted that similar reference numerals and letters refer to like items in the following drawings, and therefore, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0067] Some embodiments of the present application will be described in detail below with reference to the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0068] Reference is made to Figure 1 , Figure 2 ,Figure 10 and Figure 11 At least one disclosed embodiment provides a planetary gear press-fitting device, comprising: an adjusting device 1, a first feeding and discharging device 2, and a pair of second feeding and discharging devices 3; the first feeding and discharging device 2 is connected with the adjusting device 1; the second feeding and discharging device 3 is slidingly connected with the adjusting device 1, and the second feeding and discharging device 3 is arranged on both sides of the first feeding and discharging device 2; wherein the adjusting device 1 is configured to drive the second feeding and discharging device 3 to simultaneously approach or move away from the first feeding and discharging device 2, so that the first feeding and discharging device 2 and the second feeding and discharging device 3 grab planetary gears placed at different intervals; and a protection assembly arranged on the adjusting device 1, the protection assembly is configured to absorb the impact force of the adjusting device 1 when the second feeding and discharging device 3 is started through the wear-resistant strip 17 thereof.

[0069] In the embodiment, in order to make the sliding shaft 32 move smoothly, the diameter of the sliding shaft 32 is configured to be smaller than the width of the strip-shaped hole 12. When the device is started, the sliding shaft 32 will first move downward to contact the hole bottom surface of the strip-shaped hole 12 under the driving force of the helical groove 14 of the driving shaft 13, and then horizontally slide. As the use time of the device increases, the repeated starting impact of the sliding shaft 32 on the hole bottom surface when starting will cause the inner wall of the strip-shaped hole 12 to be concave or damaged. At this time, if the original set movement stroke is still directly used, the effective sliding will change due to the existence of the concave, that is, the sliding shaft 32 needs to move to the bottom of the concave to abut against the strip-shaped hole 12, thereby causing the driving shaft 13 to need to rotate a little more angle to achieve. In actual process, the rotation angle of the driving shaft 13 directly determines the translation distance of the sliding shaft 32. If the above problem occurs, the translation distance of the sliding shaft 32 will be wrong, affecting the grabbing precision.

[0070] Specifically, by setting the protection assembly, the wear-resistant strip 17 can be extruded when the sliding shaft 32 moves downward, and then the downward impact force is converted into a pushing force on the wear-resistant strip 17, avoiding direct impact on the inner wall of the strip-shaped hole 12.

[0071] In the embodiment, the adjusting device 1 comprises: a shell 11; a strip-shaped hole 12 corresponding to the second feeding and discharging device 3 is formed in the side wall of the shell 11; a driving shaft 13 is arranged in the shell 11, the driving shaft 13 is connected with a driving motor, a helical groove 14 corresponding to the second feeding and discharging device 3 and an annular groove 15 corresponding to the first feeding and discharging device 2 are formed in the outer wall of the driving shaft 13; the sliding shaft 32 in the second feeding and discharging device 3 extends into the corresponding helical groove 14 after passing through the corresponding strip-shaped hole 12; the sliding shaft 32 in the first feeding and discharging device 2 extends into the corresponding annular groove 15 after passing through the shell 11.

[0072] In the embodiment, when the driving shaft 13 rotates, the cooperation between the spiral groove 14 and the strip-shaped hole 12 enables the sliding shaft 32 to move along the corresponding strip-shaped hole 12.

[0073] Referring to Figure 3 , Figure 4 , Figure 5 In the embodiment, the anti-wear strips 17 are symmetrically arranged at the two opening ends of the strip-shaped hole 12; the anti-wear strips 17 are provided with adjusting holes matched with the sliding shaft 32; when the driving shaft 13 is started to drive the second feeding and discharging device 3 away from the first feeding and discharging device 2, the anti-wear strips 17 are extruded by the extrusion ring 33 arranged on the sliding shaft 32, and then move out of the strip-shaped hole 12.

[0074] Specifically, the size of the anti-wear strip 17 is slightly smaller than the size of the strip-shaped hole 12, that is, when the anti-wear strip is extruded, the anti-wear strip is extruded outward under the action of the inclined surface of the edge of the extrusion ring, and the sliding shaft includes but is not limited to a limiting protrusion arranged to avoid excessive outward movement of the anti-wear strip due to impact force when the anti-wear strip is extruded.

[0075] Referring to Figure 6 , Figure 7 , Figure 8 and Figure 9 In the embodiment, the adjusting device further includes a containing cover 18; the containing cover 18 is arranged outside the strip-shaped hole 12, and the inner groove contour of the containing cover 18 is matched with the outer contour of the anti-wear strip 17; the containing cover 18 is configured to contain the anti-wear strip 17 moved out of the strip-shaped hole 12. Specifically, a spring (not shown in the figure) is arranged between the two anti-wear strips 17, the spring is located above the extrusion ring 33, and the spring is configured to pull the extruded anti-wear strip 17 back into the strip-shaped hole 12 when the second feeding and discharging device 3 is reset.

[0076] Referring to Figure 6 , Figure 7 , Figure 8 and Figure 9 In the embodiment, the containing cover 18 plays a role in containing the anti-wear strip 17 moved out, so that the movement of the anti-wear strip 17 is stable, and the movement of the sliding shaft 32 is stable; since the outer contour of the anti-wear strip 17 is matched with the inner groove contour of the containing cover 18, that is, when the anti-wear strip 17 cannot be smoothly moved into place, whether it is over-moved or under-moved, it cannot be inserted into the containing cover 18, so that the sliding shaft 32 cannot be moved, so that the sliding shaft 32 cannot be moved, so that the equipment damage protection is realized. At the same time, the anti-wear strip 17 is configured to be pulled into the strip-shaped hole 12 under the drive of the spring, so that the strip-shaped hole 12 is sealed and protected when the machine is stopped, and in this way, the anti-wear strip 17 can be reset, and the friction loss caused by the existence of impurities in the strip-shaped hole 12 due to the long-time placement of the equipment in the factory space is avoided.

[0077] In the embodiment, the edge of the extrusion ring 33 is arranged in an inclined manner, and the edge of the extrusion ring 33 is in contact with the edge of the wear-resistant strip 17.

[0078] Referring to Figure 1 and Figure 10 In the embodiment, the first feeding and discharging device 2 and the second feeding and discharging device 3 are structurally identical, and each includes a mounting plate 31, a first sliding rail 34 vertically arranged on one side of the mounting plate 31 away from the shell 11, a first sliding block 35 slidingly arranged on the first sliding rail 34, and a negative pressure adsorption head 36 arranged on the first sliding block 35 to adsorb a planet gear.

[0079] In an optional embodiment, a through groove 37 is formed in the top surface of the first sliding block 35, and a convex strip 38 is arranged on the inner wall of the through groove 37.

[0080] In the embodiment, the pressure head 52 can enter the through groove 37, and then the pressure head 52 is pressed downward by the pressing motor 51 to press the first sliding block 35, the distance between the two convex strips 38 is less than the diameter of the pressing disc 53, and the width of the through groove 37 is greater than the diameter of the pressing disc 53, so that the pressing disc 53 cannot protrude upward from the top opening of the through groove 37 after entering the through groove 37, but can only enter the through groove 37 from the side opening of the through groove 37, so that after pressing the first sliding block 35, the pressing motor 51 can drive the pressure head 52 to move upward, and the first sliding block 35 is driven to move upward and reset by the pressing disc 53 contacting the bottom surface of the convex strip 38.

[0081] In an optional embodiment, a second sliding block 39 is arranged on one side of the mounting plate 31 facing the shell 11, a second sliding rail 16 parallel to the strip-shaped hole 12 is arranged on the outer wall of the shell 11, and the second sliding block 39 is slidingly arranged on the second sliding rail 16.

[0082] In the embodiment, when the sliding shaft 32 moves along the strip-shaped hole 12, the second sliding block 39 can move along the second sliding rail 16, so that the mounting plate 31 moves stably.

[0083] Referring to Figure 1 In an optional embodiment, the adjusting device 11 is connected with a two-axis moving pair 4, the two-axis moving pair 4 is electrically connected with a control module, the two-axis moving pair 4 includes a pair of third sliding rails 41, a third sliding block 42 is slidingly arranged on the third sliding rail 41, the shell 11 in the adjusting device 11 is connected with the third sliding block 42, a lead screw motor 43 electrically connected with the control module is arranged on one side of the third sliding rail 41, the lead screw motor 43 is connected with the third sliding block 42, and the control module is configured to control the lead screw motor 43 to drive the third sliding block 42 to move along the third sliding rail 41.

[0084] In the embodiment, the first feeding and discharging device 2 and the second feeding and discharging device 3 can be repeatedly moved between the feeding station and the mounting position by the two-axis moving pair 4. The planetary gear can be placed at the feeding station to be repeatedly mounted.

[0085] In an alternative embodiment, a pair of fourth sliding rails 44 are arranged on the third sliding block 42, and a fourth sliding block 45 is slidably arranged on the fourth sliding rails 44. A pressing device 5 is arranged on the fourth sliding block 45, which includes a pressing motor 51 electrically connected with the control module. The pressing motor 51 is connected with a pressing head 52, and the bottom of the pressing head 52 is provided with a pressing disc 53 arranged in the through slot 37. The control module is configured to control the pressing motor 51 to drive the pressing head 52 to ascend and descend, so as to drive the first sliding block 35 to ascend and descend.

[0086] In the embodiment, the fourth sliding block 45 can be connected with a corresponding motor to move by the driving of the motor. The motor is electrically connected with the control module and controlled by the control module.

[0087] Referring to Figure 1 and Figure 11 In an embodiment, the movement of the fourth sliding block 45 can drive the pressing device 5 to move to each first sliding block 35. At this time, the shell 11 does not move, and each negative pressure suction head 36 can be pressed to mount the corresponding planetary gear.

[0088] In another embodiment, a linear moving pair can also be arranged between the shell 11 and the third sliding block 42 to drive the shell 11 to move, so as to drive each first sliding block 35 to be aligned with the pressing device 5.

[0090] In summary, the planetary gear pressing device realizes the grabbing of the planetary gears by the first feeding and discharging device and the second feeding and discharging device. The adjusting device is used to drive the second feeding and discharging device to move close to or away from the first feeding and discharging device, so as to make the first feeding and discharging device and the second feeding and discharging device to match the planetary gears placed at different intervals. At the same time, the protection assembly is provided with the wear-resistant strip which is extended and retracted. When the impact force of the adjusting device is absorbed when the second feeding and discharging device is started, the starting of the second feeding and discharging device is limited, so as to avoid the position misalignment of the second feeding and discharging device caused by the power error of the driving motor, and then avoid the grabbing failure.
