Description

Technical Field

[0001] This invention relates to a machine tool, and more specifically to a vertical machining center. Background Technology

[0002] A vertical machining center is a machine tool used for machining parts. Its basic principle is to process workpieces using specific processes and tools to complete the machining task. One application requires fitting a rubber sleeve onto a round rod with an outer diameter larger than the sleeve itself. This makes fitting the rubber sleeve onto the rod very difficult and challenging. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a vertical machining tool, the advantage of which is that one end of the rubber cylinder can be easily fitted onto the spherical head on the round rod.

[0004] A vertical machining center includes an inner ring on which multiple slide bars are radially slidably connected, and an arc-shaped support rod is fixed to the inner end of each slide bar.

[0005] Each of the slide bars has a convex shaft fixed at its outer end. Two convex seats are fixed on the outer side of the inner ring. The rotating shaft is rotatably connected to the two convex seats. The rotating shaft is coaxial with the inner ring. Multiple inclined grooves are arranged in a ring on the rotating shaft. Multiple convex shafts are inserted into the multiple inclined grooves respectively.

[0006] Each of the aforementioned convex shafts has a retaining ring fixed to its upper part.

[0007] A motor frame is connected to the inner ring by screws, and a motor is connected to the motor frame by screws. A friction wheel is fixed on the output shaft of the motor, and the friction wheel drives the inner side of the rotating ring through friction.

[0008] The lower left and right ends of the inner ring are each fixed with a lifting frame. The two lifting frames are vertically slidably connected to the two supports, and the lifting frames are driven to slide by a telescopic rod. Attached Figure Description

[0023] Rubber cylinder 501; spherical head 502; round rod 503. Detailed Implementation

[0024] like Figure 4-5 As shown, this example allows for the convenient fitting of the rubber cylinder 501 onto the spherical head 502 on the round rod 503.

[0025] Since the vertical machining center includes an inner ring 101, and multiple slide bars 107 are radially slidably connected on the inner ring 101, and each slide bar 107 has an arc-shaped support rod 106 welded to its inner end, the multiple arc-shaped support rods 106 are initially gathered at the center of the inner ring 101, and then the multiple arc-shaped support rods 106 are inserted into the upper part of the rubber cylinder 501. Then, the multiple slide bars 107 are driven to move outward, which in turn drives the multiple arc-shaped support rods 106 to move outward, thereby opening up the upper part of the rubber cylinder 501, making it convenient to fit the rubber cylinder 501 onto the spherical head 502 on the round rod 503.

[0026] like Figure 4-5As shown, this example can achieve the effect of driving multiple sliders 107 and multiple arc-shaped struts 106 to move closer or further apart from each other.

[0027] Since each slider 107 has a convex shaft 108 welded to its outer end, and two convex seats 105 are welded to the outer side of the inner ring 101, the rotating shaft 201 is rotatably connected to the two convex seats 105. The rotating shaft 201 is coaxially arranged with the inner ring 101. Multiple inclined grooves 202 are arranged in a ring on the rotating shaft 201. Multiple convex shafts 108 are respectively inserted into multiple inclined grooves 202. When the rotating shaft 201 rotates on the two convex seats 105, it can drive multiple inclined grooves 202 to rotate with it, thereby driving multiple convex shafts 108 to move closer to or away from the inner ring 101, thereby driving multiple sliders 107 and multiple arc-shaped support rods 106 to move closer to or away from each other.

[0028] like Figure 4-5 As shown, this example can achieve the effect of preventing the cam shaft 108 from disengaging from the groove 202.

[0029] Since a retaining ring 109 is welded to the upper part of each cam 108, the retaining ring 109 can prevent the cam 108 from disengaging from the inclined groove 202.

[0030] like Figure 4-5 As shown, this example can achieve the effect of driving the rotor 201 to rotate on the two protrusions 105.

[0031] A motor frame 102 is connected to the inner ring 101 by screws, and a motor 103 is connected to the motor frame 102 by screws. A friction wheel 104 is connected to the output shaft of the motor 103, and the friction wheel 104 drives the inner side of the rotor 201 through friction. The motor 103 can drive the friction wheel 104 to rotate, thereby driving the rotor 201 to rotate on the two bosses 105.

[0032] like Figure 4-6 As shown, this example can achieve the effect of pulling multiple curved struts 106 out from the top of the rubber cylinder 501.

[0033] Since both ends of the lower side of the inner ring 101 are connected to the lifting frame 303 by screws, the two lifting frames 303 are vertically slidably connected to the two supports 301 respectively. The lifting frame 303 is driven to slide by the telescopic rod 302. When the telescopic rod 302 extends and retracts, it drives the lifting frame 303 to slide vertically on the support 301, thereby driving the inner ring 101, multiple slide bars 107 and multiple arc-shaped support rods 106 to rise and fall. After the multiple arc-shaped support rods 106 put the upper part of the rubber cylinder 501 onto the spherical head 502 on the round rod 503, they can drive the multiple arc-shaped support rods 106 to move upward, so that the multiple arc-shaped support rods 106 are pulled out from the upper part of the rubber cylinder 501.

[0034] like Figure 6As shown, this example can achieve the effect of preventing displacement between the rubber cylinder 501 and the spherical head 502 when multiple curved struts 106 are pulled out.

[0035] Since each bracket 301 is welded with a side frame 307, and each side frame 307 is slidably connected with a pressure column 305, the pressure column 305 is driven to slide through the telescopic rod 304. When multiple arc-shaped support rods 106 put the upper part of the rubber cylinder 501 onto the spherical head 502 on the round rod 503, they drive the two pressure columns 305 to press against both sides of the rubber cylinder 501, so that the two points on the upper part of the rubber cylinder 501 are pressed tightly onto the spherical head 502, thereby making the rubber cylinder 501 fastened to the spherical head 502. When the multiple arc-shaped support rods 106 are pulled out, there will be no displacement between the rubber cylinder 501 and the spherical head 502.

[0036] like Figure 6 As shown, this example can achieve the effect of increasing the frictional force when the pressure column 305 presses against the rubber cylinder 501.

[0037] The end of the pressure column 305 is provided with multiple protrusions 306. These protrusions 306 can increase the friction when the pressure column 305 presses against the rubber cylinder 501, preventing slippage.

[0038] like Figure 4-8 As shown, this example can achieve the effect of placing the spherical head 502 between multiple curved struts 106.

[0039] A rubber conical sleeve 401 is provided above the inner ring 101. The upper end of the rubber conical sleeve 401 has an integrally formed protrusion 406. The protrusion 406 passes through the top seat 408, which is welded to the upper part of the L-shaped frame 409. A limit pin 407 is inserted into the upper part of the protrusion 406. The rubber conical sleeve 401 is located above the inner ring 101, which facilitates the insertion of the upper part of round rods 503 of different sizes into the rubber conical sleeve 401, thereby fixing the round rods 503 of different sizes, and placing the spherical head 502 between multiple arc-shaped support rods 106.

[0040] like Figure 7-8 As shown, this example can achieve the effect of making the rubber cone sleeve 401 stably fix the upper part of the round rod 503.

[0041] Since multiple hinge rods 402 are hinged on the top seat 408, and fixed frames 405 are welded to both ends of the top seat 408, each fixed frame 405 is connected to a telescopic rod 404 by screws. A collar 403 is connected to the movable end of the two telescopic rods 404 by screws. The collar 403 is located outside the multiple hinge rods 402. When the two telescopic rods 404 extend, they drive the collar 403 to move downward, thereby driving the collar 403 to press against the multiple hinge rods 402, causing the multiple hinge rods 402 to converge and rotate, thereby causing the multiple hinge rods 402 to press against the rubber cone sleeve 401, causing the rubber cone sleeve 401 to tighten, thereby causing the rubber cone sleeve 401 to stably fix the upper part of the round rod 503.

[0042] The rubber cone sleeve 401 is used to insert a round rod 503. A spherical head 502 is fixed at the lower part of the round rod 503. Multiple arc-shaped support rods 106 are supported on the upper inner side of the rubber cylinder 501. One end of the rubber cylinder 501 is sleeved on the spherical head 502.
