Detailed Description of the Preferred Embodiment
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0022] As Figures 1 - 4As shown in the figure, the present utility model aims to solve the problem that the flat end face and grooving processing of the existing micro-commutator need to be carried out on two devices, resulting in the inability to guarantee the processing accuracy and efficiency. The following technical solutions are provided: A flat end face grooving integrated machine for a micro-commutator, including a working platform 1. A high-speed spindle box 4 is horizontally installed in the middle of the upper side of the working platform 1. A rotary chuck 22 is installed at the front end of the high-speed spindle box 4. A feeding vibrating disk 5 is arranged on one side of the high-speed spindle box 4. A linear vibrating feeding guide rail 10 is connected to the front side of the feeding vibrating disk 5. A feeding assembly is arranged on the front side of the linear vibrating feeding guide rail 10 for conveying the micro-commutator on the linear vibrating feeding guide rail 10 to the rotary chuck 22. A feed precision slide table 2 is installed on the other side of the high-speed spindle box 4. A tool mounting platform 20 that can move left and right is arranged on the upper side of the feed precision slide table 2. A product size adjustment slide table assembly that can move back and forth is arranged on the upper side of the tool mounting platform 20. A tool mounting seat 17 is installed on the side of the product size adjustment slide table assembly facing the rotary chuck 22. At least one processing tool 18 extending to the position of the rotary chuck 22 is installed on the tool mounting seat 17. By setting the feeding assembly, it can cooperate with the linear vibrating feeding guide rail 10 and the feeding vibrating disk 5 to automatically install the micro-commutator onto the rotary chuck 22. Multiple processing tools 18 can be installed on the tool mounting seat 17. The position of the tool can be precisely adjusted through the product size adjustment slide table assembly, and multiple processes of the micro-commutator can be carried out simultaneously, improving the processing efficiency.
[0023] Specifically, a surrounding enclosing side plate can be arranged on the upper side of the working platform 1, and the processing can be carried out in an independent environment during processing, which can improve the processing accuracy. The feed precision slide table 2 operates automatically and is driven by the configured motor to drive the processing tool 18 to move along the radial direction of the rotary chuck 22, thereby controlling the depth of the cutting groove and the flat end face. The axial position of the processing tool 18 on the micro-commutator can be adjusted through the product size adjustment slide table assembly. After the adjustment is completed, only the feed precision slide table 2 needs to drive the tool mounting platform 20 to move back and forth to repeatedly process the micro-commutator, and the processing efficiency is relatively high.
[0024] In this embodiment, as Figure 2 and 4As shown in the figure, the product size adjustment slide table assembly includes an adjustment mounting base 13 arranged in the front-rear direction on the upper side of the tool mounting platform 20. A slide rail 15 is arranged between the adjustment mounting bases 13. An adjustment slide seat 14 is arranged on the upper side of the slide rail 15. A fine adjustment micrometer 19 is installed on the front-side adjustment mounting base 13. The tool mounting seat 17 is installed on the upper side of the adjustment slide seat 14. By controlling and adjusting the position of the adjustment slide seat 14 with the fine adjustment micrometer 19, the size of the micro-commutator can be precisely machined. The adjustment precision of the fine adjustment micrometer 19 is relatively high and can be operated according to the processing requirements.
[0025] Meanwhile, as Figure 4 shown in the figure, a limit screw 16 is arranged through the adjustment mounting base 13 at the rear side of the adjustment slide seat 14, which can limit the linear position of the adjustment slide seat 14 to prevent the processing tool 18 from hitting the rotary chuck 22.
[0026] As a specific structure of the tool mounting seat 17, the tool mounting seat 17 has a frame structure. At least two processing tools 18 are horizontally inserted inside the tool mounting seat 17. The installation is simple, the installation position of the processing tool 18 can be adjusted, two kinds of tools can be installed at the same time, and fixing screws can be installed on the top of the tool mounting seat 17 to fix the processing tool 18.
[0027] In this embodiment, the processing tool 18 includes a commutator end face cutting tool and a commutator side wall grooving tool, which can process the end face and side wall of the micro-commutator at the same time.
[0028] In this embodiment, as a specific way of the feeding component, the feeding component includes a conveying rod 11 arranged in the left-right direction at the front end of the linear vibration feeding guide rail 10. At least one positioning groove matching the shape of the micro-commutator is arranged on the upper side of the first end of the conveying rod 11. A feeding cylinder 7 is arranged at the second end of the conveying rod 11. A ejector cylinder 8 arranged in the front-rear direction is also installed on the first end of the conveying rod 11. The ejector pin 12 on the extending rod of the ejector cylinder 8 corresponds to the positioning groove. By the cooperation of the feeding cylinder 7 and the ejector cylinder 8, the micro-commutator on the linear vibration feeding guide rail 10 can be fed into the rotary chuck 22 with high efficiency.
[0029] Specifically, the linear vibration feeding guide rail 10 continuously conveys the micro-commutators in the feeding vibrating bowl 5 to the positioning grooves on the conveying rod 11. The conveying rod 11 and the ejector cylinder 8 can move horizontally together to the position where the positioning groove corresponds to the rotary chuck 22. Then, the ejector cylinder 8 can push the micro-commutator in the positioning groove into the rotary chuck 22 to clamp it. When the conveying rod 11 horizontally conveys the micro-commutator, the end of the linear vibration feeding guide rail 10 can be blocked, so that the micro-commutator will not fall. At the same time, photoelectric sensors 9 are installed on the upper sides of the front end and the rear end of the linear vibration feeding guide rail 10, which can sense the micro-commutators at different positions on the linear vibration feeding guide rail 10 to realize automatic feeding.
[0030] In this embodiment, a spindle motor 3 is installed on one side of the high-speed spindle box 4. The spindle motor 3 is connected to the spindle in the high-speed spindle box 4 through a belt transmission assembly, which can achieve stable transmission.
[0031] As Figures 1 - 2 shown, a blanking chute 21 is provided on the front side of the high-speed spindle box 4 to facilitate the blanking of the micro-commutators after processing.
