[0013] By adopting the above technical solution, the inspection port can facilitate the inspection and maintenance of the cam and the rocker arm.

[0014] Optionally, the cam is detachably mounted on the input shaft, and the swing arm is detachably mounted on the cam.

[0015] By adopting the above technical solution, the detachable cam and rocker arm can be replaced, thereby changing the swing amplitude of the rocker arm and adjusting the sliding distance of the output shaft according to the groove to be machined.

[0016] Optionally, a positioning block can be detachably installed on the machine body, and a positioning groove is provided on the ring sleeve.

[0017] By adopting the above technical solution, the positioning block can be used to position the ring sleeve, thereby adjusting the position of the ring sleeve according to the sliding distance of the output shaft, and driving the position adjustment of the guide rod.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] This application discloses a slot power head, as shown in the embodiments below. Figure 1 , Figure 2 and Figure 3The system includes a body 1, on which an input shaft 2 is rotatably mounted. One end of the input shaft 2 extends out of the body 1, while the other end is installed inside the body 1. The body 1 is mounted on a power turret, and the end of the input shaft 2 extending out of the body 1 is inserted into the power turret to connect to a power source, thus enabling the input shaft 2 to rotate. A cam 3 is fixedly mounted at one end of the input shaft 2 inside the body 1. A rocker arm 4 is eccentrically mounted on the cam 3, and an output shaft 5 is mounted on the rocker arm 4. The rocker arm 4 is hinged to both the cam 3 and the output shaft 5. The rotation of the input shaft 2 drives the cam 3... Rotating drive arm 4 drives output shaft 5 to slide back and forth. Output shaft 5 is used to install slotting tool. The reciprocating output shaft 5 drives slotting tool to reciprocate to perform slotting. Guide rods 6 are installed on both sides of the machine body 1 in the width direction. Guide grooves 7 are opened on the output shaft 5 corresponding to the guide rods 6. The guide rods 6 are slidably set in the guide grooves 7. By opening the guide grooves 7 and setting the guide rods 6, the probability of the output shaft 5 deflecting during sliding is reduced by the cooperation of the guide rods 6 and the guide grooves 7, thereby improving the accuracy of slotting.

[0034] Reference Figure 2 , Figure 3 and Figure 4 The machine body 1 has an inspection port 9 at the connection between the cam 3 and the rocker arm 4. A cover plate 10 is detachably installed on the inspection port 9. The condition of the connection between the cam 3 and the rocker arm 4 can be observed by removing the cover plate 10. The cam 3 is detachably installed on the input shaft 2 by bolts, and the rocker arm 4 is detachably hinged to the cam 3 by bolts. When the rocker arm 4 and the cam 3 are disassembled, the rocker arm 4 can slide away from the cam 3, and the cam 3 can be removed from the inspection port 9 by sliding. By replacing different models of cam 3, the swing amplitude of the rocker arm 4 can be adjusted, thereby adjusting the sliding distance of the output shaft 5, and thus processing slots of different depths.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The machine body 1 is provided with a ring sleeve 8, which is fitted over the output shaft 5. A positioning block 11 is detachably installed on the machine body 1. A positioning groove 12 is provided on the ring sleeve 8. The ring sleeve 8 is used to guide the output shaft 5. A guide rod 6 is detachably installed on the machine body 1 and passes through the ring sleeve 8. An installation plate 13 is detachably installed on the machine body 1, and the guide rod 6 is installed on the installation plate 13. By installing different types of positioning blocks 11, the position of the ring sleeve 8 can be adjusted, thereby adjusting the position of the guide rod 6 passing through the ring sleeve 8. By adjusting different types of installation plates 13, the position of the guide rod 6 can be adjusted to match the ring sleeve 8. When the stroke of the output shaft 5 changes, by adjusting the position of the guide rod 6, the guide rod 6 can better match and guide the sliding of the output shaft 5, reducing the probability of the output shaft 5 deflection.

[0036] Reference Figure 1 and Figure 5The machine body 1 is equipped with a cooling nozzle 14, which faces the side of the output shaft 5 where the tool is mounted. The machine body 1 is equipped with a flow channel 15, which is connected to a coolant source. The coolant is delivered to the tool processing area through the flow channel 15 to cool the tool and the workpiece, thereby reducing the probability of tool damage caused by the tool and workpiece heating up during processing. In this embodiment, multiple outlets 16 of the flow channel 15 away from the cooling nozzle 14 are provided. According to actual needs, one outlet 16 is selected to connect to the coolant source, and the other outlets 16 are blocked, so as to facilitate the connection of the coolant source in different directions.

[0037] The implementation principle of this application embodiment is as follows: The machine body 1 is installed on the power turret, and the input shaft 2 is connected to the power source of the power turret. Then, according to the actual situation, the outlet 16 of the appropriate direction is selected to connect the coolant. A suitable slotting tool is installed on the output shaft 5. When slotting, the power source of the power turret drives the input shaft 2 to rotate. The input shaft 2 drives the cam 3 to rotate and drives the swing arm 4 to slide and rotate. The swing arm 4 drives the output shaft 5 to slide back and forth, thereby driving the slotting tool to slide back and forth to process the workpiece groove. When it is necessary to adjust the stroke of the slotting tool, the inspection port 9 is opened, the cam 3 and the swing arm 4 are disassembled and a suitable cam 3 is replaced. The swing arm 4 is then slid to drive the output shaft 5 to slide and is reinstalled on the replaced cam 3. At the same time, the suitable positioning block 11 and mounting plate 13 are replaced to adjust the position of the adjusting ring 8 and the guide rod 6. After that, the cover plate 10 is installed and the grooves of different depths are processed.

[0038] It should be noted that the above embodiments are only used to illustrate this application and are not intended to limit the technical solutions described in this application. Although this specification has described this application in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to this application. All technical solutions and improvements that do not depart from the spirit and scope of this application should be covered within the scope of the claims of this application.
