Description

Technical Field

[0001] This utility model relates to a power turret, and more particularly to a turret with a fixed seat stabilization component that can stabilize the milling spindle mounting base and enable the milling spindle to rotate smoothly. Background Technology

[0002] A power turret is a machining device that has different types of machining tools mounted on its cutter head, and can perform different machining operations on workpieces for different purposes using different types of machining tools.

[0003] The existing power turret includes a machining component and a tool changing component. The machining component has a support shaft tube, and the tool changing component includes a tool changing shaft tube rotatably fitted onto the support shaft tube, and a tool head fixed to one end of the tool changing shaft tube. A bearing is provided between the support shaft tube and the tool changing shaft tube, allowing the tool changing shaft tube and the tool head to rotate around the tool changing shaft tube, thereby achieving machining with different cutting tools. The machining component has a milling axis fixing seat at one end of the support shaft tube, and a milling axis passing through the milling axis fixing seat is disposed within the support shaft tube to drive the machining tool for machining.

[0004] However, when the milling spindle mount located at one end of the support tube relies solely on needle roller bearings for radial support without adequate support, the force generated by the milling spindle rotating and performing milling operations adversely affects the radial clearance inside the bearings. This makes the milling spindle mount unstable, hinders the smooth rotation of the milling spindle within it, and leads to problems such as excessive vibration, abnormal heat generation, and shortened bearing life. Therefore, it is clear that there is room for improvement and enhancement of existing power turrets. Utility Model Content

[0005] In view of the aforementioned shortcomings and deficiencies of the prior art, the present invention provides a turret with a fixed seat stabilizing assembly that can stably support the milling axis fixed seat and allow the milling axis therein to rotate smoothly.

[0006] To achieve the above objectives, the technical means adopted by this utility model is a turret with a fixed base stabilization assembly, which includes:

[0007] A machining assembly includes a support shaft tube and a milling shaft fixing seat; the support shaft tube is elongated and includes an axial direction and two ends positioned opposite each other along the axial direction; the milling shaft fixing seat is located at one end of the support shaft tube.

[0008] A tool changing assembly includes a tool changing shaft tube and a tool disc; the tool changing shaft tube is a long tube with two opposite ends and is rotatably fitted onto the support shaft tube; the tool disc is fixed to one end of the tool changing shaft tube and can rotate relative to the milling shaft fixing seat with the tool changing shaft tube.

[0009] A support member, which is annular and includes an inner circumferential surface and an outer circumferential surface with a circular outline; the support member surrounds the milling shaft fixing seat and abuts against the cutter head with its outer circumferential surface; and

[0010] A fixed seat stabilizing assembly is located between the support member and the milling shaft fixed seat and includes an active clamping member and a driven clamping member; the active clamping member has an inclined abutment surface, and the driven clamping member has an inclined abutment surface. The two abutment surfaces of the active clamping member and the driven clamping member are inclined in opposite directions and abut against each other. The active clamping member and the driven clamping member can move along the abutment surfaces and radially push against the milling shaft fixed seat and the support member, respectively.

[0011] The improved effects of the present invention are as follows: the turret of the present invention with a fixed seat stabilizing assembly has the fixed seat stabilizing assembly provided between the support member and the milling spindle fixed seat; the active clamping member and the driven clamping member of the fixed seat stabilizing assembly have abutting surfaces that are inclined in opposite directions and abut against each other, so that the active clamping member and the driven clamping member can radially push against the milling spindle fixed seat and the support member respectively, thereby providing sufficient support for the milling spindle fixed seat, making the milling spindle fixed seat less susceptible to the influence of the internal radial clearance of the bearing, and helping the milling spindle to rotate smoothly and stably within the milling spindle fixed seat.

[0019] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means employed by the present invention to achieve its intended creative purpose.

[0020] like Figures 1 to 5 As shown, a preferred embodiment of the turret with a fixed base stabilization assembly of the present invention includes a housing 10, a processing assembly 20, a tool changing assembly 30, a support member 40, and a fixed base stabilization assembly 50.

[0021] like Figures 1 to 5 As shown, the housing 10 has an internal accommodating space, and the housing 10 includes an output terminal and an input terminal that are positioned opposite each other.

[0022] like Figures 1 to 5 As shown, the machining assembly 20 includes a support shaft tube 21, a milling shaft mounting base 22, a milling shaft 23, and a machining motor 24. The support shaft tube 21 is elongated and includes an axial direction, and a first end and a second end that are positioned opposite each other along the axial direction. The milling shaft mounting base 22 includes a receiving groove 221, a support neck 222, and a plurality of through holes 223. The receiving groove 221 is located inside the milling shaft mounting base 22 and can accommodate bevel gears and other parts used for power transmission. The support neck 222 is located at the bottom of the milling shaft mounting base 22, on the same side as the bottom of the receiving groove 221, and is fixed to the first end of the support shaft tube 21. The support neck 222 includes an outer peripheral surface. In a preferred embodiment of the present invention, the support neck 222 is annular. Each of the through holes 223 passes through the receiving groove 221 from the bottom of the receiving groove 221, and the plurality of through holes 223 surround the support neck 222.

[0023] like Figures 1 to 5 As shown, the milling shaft 23 is a long rod-shaped component. It rotatably passes through the support shaft tube 21, into the milling shaft mounting base 22, and connects to a bevel gear within the mounting base 22. The machining motor 24 is mounted at the input end of the housing 10. It connects to the milling shaft 23 and drives it to rotate within the support shaft tube 21. The detailed structure and connection relationship of the milling shaft 23 and the machining motor 24 are existing technology and will not be described in detail here.

[0024] like Figures 1 to 5As shown, the tool changing assembly 30 includes a tool changing shaft tube 31, a tool disc 32, and a tool changing motor 33. The tool changing shaft tube 31 is elongated and includes a first end and a second end positioned opposite each other, coaxially fitted onto the support shaft tube 21, and is rotatable relative to the support shaft tube 21. Specifically, a bearing is provided between the tool changing shaft tube 31 and the support shaft tube 21 to assist the rotation of the tool changing shaft tube 31 relative to the support shaft tube 21. The tool changing motor 33 is located at the input end of the housing 10, and is connected to the tool changing shaft tube 31 via gears or other mechanisms, thereby driving the tool changing shaft tube 31 to rotate relative to the support shaft tube 21.

[0025] like Figures 1 to 5 As shown, the cutter head 32 is used to mount multiple machining tools for different machining purposes. The cutter head 32 is fixed to the first end of the tool changer tube 31 and can rotate relative to the milling spindle fixing seat 22 with the tool changer tube 31, thereby performing different machining for different purposes with different machining tools on the cutter head 32. The cutter head 32 includes a fixing seat receiving groove 321, a clamping member receiving groove 322, and a support portion 323. The fixing seat receiving groove 321 is located inside the cutter head 32 and accommodates the milling spindle fixing seat 22; the clamping member receiving groove 322 is located inside the cutter head 32 and is recessed in the bottom of the fixing seat receiving groove 321, and the support neck 222 of the milling spindle fixing seat 22 is accommodated in the clamping member receiving groove 322; the support portion 323 is located on the groove wall of the clamping member receiving groove 322.

[0026] like Figures 1 to 5 As shown, the abutment 40 is used to support the cutter head 32, allowing the cutter head 32 to rotate smoothly and stably relative to the milling shaft fixing seat 22. The abutment 40 is annular, housed within the clamping member receiving groove 322, and surrounds the support neck 222 of the milling shaft fixing seat 22. The abutment 40 includes an outer circumferential surface and an inner circumferential surface located on its outer and inner sides, respectively. The outer circumferential surface of the abutment 40 has a circular outline and abuts against the abutment portion 323, that is, against the groove wall of the clamping member receiving groove 322. In a preferred embodiment of this utility model, the abutment 40 is a wear-resistant ring; in application, the abutment 40 can also be a bearing or a self-lubricating bearing; as long as the abutment 40 can assist the cutter head 32 to rotate smoothly and stably relative to the milling shaft fixing seat 22, this utility model does not impose specific limitations on the type of the abutment 40.

[0027] like Figures 1 to 5As shown, the fixing seat stabilizing assembly 50 is housed within the clamping member receiving groove 322 and is located between the support neck 222 of the milling shaft fixing seat 22 and the abutment member 40. The fixing seat stabilizing assembly 50 includes an active clamping member 51, a driven clamping member 52, and a plurality of clamping drive members 53; the active clamping member 51 is annular and sleeved on the support neck 222, the active clamping member 51 is provided with a plurality of screw holes 511, and the outer diameter of the active clamping member 51 gradually tapers towards the cutter head 32, forming an inclined and annular abutment surface; the driven clamping member 52 is annular, sleeved on the active clamping member 51, and is located between the active clamping member 51 and the driven clamping member 52. Between the driven clamping member 51 and the supporting member 40, the inner diameter of the driven clamping member 52 gradually expands towards the cutter head 32, forming an inclined and annular abutment surface. The abutment surface of the driven clamping member 52 and the abutment surface of the active clamping member 51 are inclined in opposite directions and abut against each other. Each clamping drive member 53 is a bolt, and multiple clamping drive members 53 pass through multiple through holes 223 of the milling shaft fixing seat 22 and are screwed into multiple screw holes 511 of the active clamping member 51. In a preferred embodiment of the present invention, the abutment surface of the driven clamping member 52 and the abutment surface of the active clamping member 51 have the same slope.

[0028] like Figure 6 and Figure 7 As shown, when the user tightens the screwdriver through the receiving groove 221 of the milling shaft fixing seat 22, the active clamping member 51 moves radially toward the cutter head 32 of the tool changing assembly 30 along the support shaft tube 21. At this time, since the abutting surfaces of the active clamping member 51 and the driven clamping member 52 are inclined in opposite directions and abut against each other, the driven clamping member 52 will radially push against the support member 40 along the abutting surface, so that the support member 40 is tightly abutted against the support portion 323 of the cutter head 32, that is, tightly abutted against the groove wall of the clamping member receiving groove 322. At this time, since the cutter head 32 is fully supported, it can rotate smoothly and stably relative to the milling shaft holder 22. Furthermore, since the milling shaft holder 22 located at the first end of the support shaft tube 21 is fully supported, the milling shaft holder 22 is not easily affected by the internal radial clearance of the bearing, which also helps the milling shaft 23 to rotate smoothly and stably within the milling shaft holder 22 and drive the tool stably.

[0029] like Figure 3 As shown, preferably, the driven clamping member 52 is provided with a notch 521; in this way, when the active clamping member 51 pushes against the driven clamping member 52, the notch 521 provided in the driven clamping member 52 makes the driven clamping member 52 easier to deform, which helps the driven clamping member 52 to push against the support member 40 radially.

[0030] In a preferred embodiment of this invention, the clamping drive 53, screwed into the screw hole 511 of the active clamping member 51, pulls the active clamping member 51 to move axially, driving the driven clamping member 52 to push against the support member 40. In application, the clamping drive 53 can also be used to push the active clamping member 51 to move axially, driving the driven clamping member 52 to push against the support member 40.

[0031] In a preferred embodiment of this utility model, the fixed seat stabilizing assembly 50 is provided with an annular active clamping member 51 and an annular driven clamping member 52. In application, the fixed seat stabilizing assembly 50 can also be provided with both the active clamping member 51 and the driven clamping member 52 as wedge-shaped blocks, and with more than one active clamping member 51 and more than one driven clamping member 52. As long as the active clamping member 51 and the driven clamping member 52 can move relative to each other along the abutment surface and radially push against the support neck 222 and the support member 40 of the milling shaft fixed seat 22, the fixed seat stabilizing assembly 50 can apply force to the milling shaft fixed seat 22 and the cutter head 32 respectively with the active clamping member 51 and the driven clamping member 52, provide sufficient support force for the milling shaft fixed seat 22, and enable the milling shaft 23 installed therein to rotate smoothly and drive the bevel gear stably, thereby driving the tool stably.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Anyone skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
