[0024] The concept, specific structure and generated technical effect of the utility model will be clearly and completely described below in combination with embodiments and drawings, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, and other embodiments obtained by the person skilled in the art without creative labor based on the embodiments of the utility model all belong to the protection scope of the utility model. In addition, all the coupling / connection relations involved in the patent are not single component direct connection, but can be composed of better coupling structure by adding or reducing coupling auxiliary parts according to the specific implementation situation. The various technical features in the utility model creation can be interactively combined under the premise of no mutual contradiction and conflict.
[0025] With reference to Figures 1-5 , the utility model provides:
[0026] A horizontal type gear pressing jig, including jig bottom plate 1, jig bottom plate 1 is provided with gear pressing cylinder 2, motor positioning seat 3 and stroke baffle 4, the top pin sleeve 5 is provided on stroke baffle 4, the movable top pin 6 is movably arranged in the inside of top pin sleeve 5, the position of movable top pin 6 is adapted to the position of motor shaft of motor 9 needing to press into gear workpiece 91, gear pressing cylinder 2 and stroke baffle 4 are arranged at the both sides of motor positioning seat 3 respectively, the position of the output shaft of gear pressing cylinder 2 corresponds the position of motor 9 and is used to drive motor 9 to press towards gear workpiece 91 to make gear workpiece 91 press into the motor shaft of motor 9.
[0027] In practical application, before assembling the gear workpiece 91, the motor 9 to be installed on the gear workpiece 91 is positioned on the motor positioning seat 3. The motor 9 can move axially on the motor shaft within the motor positioning seat 3. The corresponding gear workpiece 91 is then fitted onto the outer end of the ejector pin 6, with the outer end of the ejector pin inserted into the center hole of the gear workpiece 91. The end of the gear workpiece 91 furthest from the motor 9 rests against the outer end of the ejector pin sleeve 5. After the gear pressing operation begins, the gear pressing cylinder 2 starts working. The output shaft of the gear pressing cylinder 2 extends and drives the motor 9 to press against the ejector pin sleeve 5, causing the motor shaft of the motor 9 to be pressed into the center hole of the gear workpiece 91. During the process of the motor shaft being pressed into the center hole of the gear workpiece 91, the ejector pin 6 in the center hole of the gear 91 is pushed out by the motor shaft of the motor 9. After the ejector pin is completely pushed out, the motor 9 completes the installation of the gear workpiece 91.
[0028] In some embodiments, the travel baffle 4 is provided with a ejector pin sleeve channel 41, the ejector pin sleeve 5 is disposed inside the ejector pin sleeve channel 41, and the ejector pin sleeve channel 41 is an installation channel for the ejector pin sleeve 5.
[0029] In some embodiments, the ejector sleeve 5 has an inner hole 51, which is a stepped through hole. The inner hole 51 includes a large hole portion and a small hole portion. The movable ejector 6 includes an ejector seat 61 and an ejector body 62. The ejector seat 61 is sized to fit the large hole portion of the inner hole 51 and is movably disposed in the large hole portion. The ejector body 62 is sized to fit the small hole portion of the inner hole 51 and is movably disposed in the small hole portion. In actual implementation, a spring (not shown in the figure) is provided inside the ejector sleeve 5 to elastically eject the ejector 6. When the motor shaft of the motor 9 is pressed into the center hole of the gear workpiece 91, the motor shaft or the ejector 6 is forced to retract against the elastic force of the spring until the ejector 6 is completely disengaged from the gear workpiece 91, thereby completing the assembly of the gear workpiece 91.
[0030] In some embodiments, a locking hole 42 is provided on the stroke baffle 4, which communicates with the ejector sleeve channel 41. A locking screw is provided in the locking hole 42 to lock the ejector sleeve 5 within the ejector sleeve channel 41. The locking function of the locking screw on the ejector sleeve 5 prevents positional changes during application, ensuring machining accuracy.
[0031] In some embodiments, the ejector sleeve channel 41 is a through hole, and a fine-tuning screw 43 is provided at the outer end of the locking sleeve channel 41. The inner end of the fine-tuning screw 43 extends into the ejector sleeve channel 41 and is used to adjust the position of the ejector sleeve 5 within the ejector sleeve channel 41. During adjustment, the fine-tuning screw 43 can be used for specific fine-tuning for different product models. Specifically, the locking screw is loosened, the position of the ejector sleeve 5 is adjusted using the fine-tuning screw 43, and after the position of the ejector sleeve 5 is adjusted, the ejector sleeve 5 is locked again using the locking screw.
[0032] In some embodiments, the upper end of the motor positioning seat 3 has an arc-shaped positioning groove 31, the shape of which matches the outer peripheral contour of the motor 9. In specific implementation, the motor 9, which needs to be aligned with the gear, is placed in the arc-shaped positioning groove 31 to ensure that the motor shaft of the motor 9 is on the same axis as the ejector pin 6 and the cylinder shaft of the gear pressing cylinder 2, thereby ensuring accuracy.
[0033] In some embodiments, a mounting groove 11 is provided on the base plate 1 of the fixture, and the lower ends of the motor positioning seat 3 and the stroke baffle 4 are both disposed in the mounting groove 11. The mounting groove 11 can improve the changeover speed while ensuring assembly accuracy, thereby improving application flexibility and versatility.
[0034] In some embodiments, the gear pressing cylinder 2 is mounted on the fixture base plate 1 via a cylinder mounting seat 21.
[0035] In some embodiments, the fixture base plate 1 is provided with a cylinder solenoid control valve 7 for use with the gear pressing cylinder 2. One end of the cylinder solenoid control valve 7 is connected to the gear pressing cylinder 2, and the other end of the cylinder solenoid control valve 7 is connected to an external air source.
[0036] In some embodiments, a control box 8 and control buttons 81 are provided on the base plate 1 of the fixture. The control box 8 and control buttons 81 are the control devices of the fixture, and existing known control methods can be used, which will not be described in detail here.
[0037] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.
