Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 The present invention provides a technical solution: an adjustable power head, including a fixed bracket 101, a power box 102 is provided on one side of the fixed bracket 101, a servo motor 103 is fixed to the top of the power box 102 by mounting bolts, a power connection mechanism is provided at the bottom of the servo motor 103 on one side and one end of the power box 102, and a height adjustment mechanism is provided at the connection between the side of the power box 102 and the fixed bracket 101.

[0025] The height adjustment mechanism includes a height adjustment component located at the midpoint of the connection between the fixed bracket 101 and the power box 102. Guide sliding components are provided on both sides of the fixed bracket 101 and the power box 102. The height of the power box 102 can be adjusted by the height adjustment component according to the usage conditions to meet more processing needs.

[0026] To facilitate adjustment based on processing conditions and adapt to various processing needs using the height adjustment component, in this embodiment, preferably, the height adjustment component includes an internally threaded sleeve 1013 welded and fixed inside one end of the power housing 102, a lead screw 1012 rotating at the middle position of one end of the fixed bracket 101, and the internal structure of the lead screw 1012 matching that of the internally threaded sleeve 1013. A limit ring is provided at the bottom end of the lead screw 1012, and a forward and reverse geared motor 1011 is fixed at the top end of the lead screw 1012 on the upper surface of the fixed bracket 101. When the forward and reverse geared motor 1011 is energized, it drives the lead screw 1012 to rotate. When the lead screw 1012 rotates, it causes the internally threaded sleeve 1013 and the power housing 102 to rise above the outer surface of the lead screw 1012, facilitating height adjustment.

[0027] To facilitate more stable height adjustment of the power housing 102 via the guide sliding assembly, in this embodiment, preferably, the guide sliding assembly includes guide grooves 1014 formed on both sides of the end of the fixed bracket 101. A guide slider 1015 slides inside the guide groove 1014. The end of the guide slider 1015 is fixed to the side of the power housing 102 by welding. When adjusting the height, the power housing 102 can drive the guide slider 1015 to slide within the guide groove 1014, thus stabilizing the height and adjustment. Two fixing bolts 1016 are threadedly connected to both sides of the end of the power housing 102. The fixed bracket 101 has internal threaded holes 1017 that match the fixing bolts 1016 at equal intervals on both sides. After the height is adjusted, the fixing bolts 1016 can be rotated to fit into the internal threaded holes 1017 to fix and stabilize the housing.

[0028] The power connection mechanism includes a drive assembly located at the bottom of the servo motor 103 inside the power housing 102. Two sets of driven assemblies are provided on the bottom side of the drive assembly. Clamping assemblies are provided at the ends of the driven assemblies and on one side and one end of the power housing 102. A stabilization control assembly is provided inside the clamping assembly. When the power head is in use, the servo motor 103 is installed at the top of the power housing 102, and the driven shaft 1027 on one end and one side is driven by the power connection mechanism to rotate simultaneously, so as to complete the end face and side face machining of the part in one clamping.

[0029] In order to facilitate the simultaneous rotation of the driven shaft 1027 on one side and the other end by means of the drive assembly, in this embodiment, preferably, the drive assembly includes an active shaft 1025 fixedly installed at the end of the servo motor 103 inside the power housing 102. The bottom end of the active shaft 1025 is welded with an active bevel gear 1024, which can drive the active shaft 1025 and the active bevel gear 1024 to rotate when the servo motor 103 is vertically mounted, so that the active bevel gear 1024 can drive the driven bevel gear 1026 and the driven shaft 1027 to drive, thus facilitating the drive operation.

[0030] To facilitate the driving operation of the mounting head 1022 and the mounted cutter head via the driven component, in this embodiment, preferably, the driven component includes an integral base 1021 formed on one side and one end of the power housing 102. A driven shaft 1027 is mounted inside the integral base 1021 via bearings. A driven bevel gear 1026 is welded and fixed to one end of the driven shaft 1027. The driven bevel gear 1026 meshes with the driving bevel gear 1024. The other end of the driving bevel gear 1024 is provided with a mounting head 1022, which can mesh with the surface of the driven bevel gear 1026 when the driving bevel gear 1024 rotates, allowing the driven shaft 1027 and the mounting head 1022 to rotate, thus facilitating the rotation of the mounting head 1022 to drive the cutter head operation.

[0031] In order to facilitate the reinstallation and stable control of the driven shaft 1027 by means of the clamping assembly, in this embodiment, preferably, the clamping assembly includes a reinforcing cover plate 1023 that is disposed through the outer surface of the driven shaft 1027 and matches the end surface of the integral seat 1021. The reinforcing cover plate 1023 is fixed to the end surface of the integral seat 1021 by mounting bolts. After the reinforcing cover plate 1023 is fixedly installed, the ball bearing 1029 can be contacted in the annular rolling groove 1020 at the edge of the inner surface of the integral seat 1021 and the reinforcing cover plate 1023 for stable control of rotation.

[0032] To facilitate more stable control of the driven shaft 1027's rotation via a stabilization control component, in this embodiment, preferably, the stabilization control component includes a stabilization mounting ring 1028 integrally disposed on the outer surface of the driven shaft 1027's end. Ball bearings 1029 are equidistantly rolled at both edges of the stabilization mounting ring 1028. An annular rolling groove 1020 is formed at the inner edge of the integral base 1021, which rolls in contact with the ball bearings 1029. This allows the driven shaft 1027 to rotate, causing the stabilization mounting ring 1028 to rotate. When the stabilization mounting ring 1028 rotates, the outer surface of the ball bearings 1029 contacts the inner surface of the annular rolling groove 1020, resulting in stable rolling control and more stable drive operation.

[0033] The forward and reverse geared motor 1011 in this utility model is model 90, 120W DC 24V.

[0034] The working principle and usage process of this utility model: When using this adjustable power head, first close the fixed bracket 101 at the installation position on the machine tool slide and fix it with the mounting bolts. Then fix the power box 102 and the servo motor 103 on the fixed bracket 101. Therefore, the servo motor 103 is installed at the top during installation. The structure is compact and the size is small. The bracket is directly installed on the tool rack and does not occupy the space behind the tool rack. This solves the problem of insufficient space behind the tool rack and makes it impossible to install the power head. This makes the servo motor 103 not occupy the space behind the tool rack and makes installation more convenient.

[0035] When using the device after installation, the center height can be adjusted according to the position of the workpiece. The forward and reverse geared motor 1011 can be powered on to drive the lead screw 1012 to rotate. When the lead screw 1012 rotates, it drives the internal threaded sleeve 1013 and the power box 102 to rise on the outer surface of the lead screw 1012. At the same time, it drives the guide slider 1015 to slide stably inside the guide groove 1014. After adjusting the power box 102 to the height to be used, the fixing bolt 1016 is rotated again to embed into the internal threaded hole 1017 to reinforce the power box 102. This allows the servo motor 103 to be placed at the top for easy installation when the power head is installed. The height can be easily adjusted according to the processing situation to adapt to more processing needs and improve the convenience of installation and center height adjustment of the power head during use. In addition, during processing, the position of the fixing bracket 101 can be adjusted to allow the side driven shaft 1027 to extend outward for easy processing.

[0036] Finally, when the power head is used after installation, the machining head is clamped and fixed inside the mounting head 1022. The servo motor 103 drives the active rotating shaft 1025 and the active bevel gear 1024 to rotate. When the active bevel gear 1024 rotates, it drives the driven bevel gear 1026 and the driven rotating shaft 1027 to rotate. When the driven rotating shaft 1027 rotates, it drives the stabilizing mounting ring 1028 to rotate. When the stabilizing mounting ring 1028 rotates, it makes the surface of the ball 1029 contact the inside of the annular rolling groove 1020 to roll and stabilize the driven rotating shaft 1027. The driven rotating shaft 1027 then rotates stably, driving the mounting head 1022 and the machining head to rotate for machining. This makes the power head convenient for one-sided stable control drive operation, saving motor costs, reducing tool change time, and, in conjunction with the machine tool's position control, achieving the completion of end and side machining of the part in one clamping.
