Description

Technical Field

[0001] The invention relates to the technical field of bicycle accessory processing, and in particular to an adjustable multi-station pipe cutting device. Background Art

[0002] During the production of bicycle frames, in order to ensure the accuracy of the frame tube docking and improve the welding quality of the bicycle frames, it is usually necessary to cut the bicycle frame tubes in a straight line. To facilitate the straight line cutting of the bicycle frames, workers usually use a cutting device. The existing cutting device usually consists of a circular saw cutting assembly, a cutting table and a clamping seat.

[0003] For example, the utility model application number CN201910378498.8 discloses a pipe cutting machine, which specifically includes a cutting table and a cutting saw arranged on one side of the cutting table. The cutting table is provided with a support base, and a vise is provided on the support base. The two jaws of the vise are provided with elongated claws, and the sides where the claws are close to each other are provided with a slot arranged along the length direction, and the slot is flared. The support base is provided with an elongated support rod, and the support rod is located below between the two jaws of the vise, and the sides where the two jaws of the vise are close to each other are provided with a groove for the support rod to be embedded. The middle parts of the claws and the support rod are provided with notches for the saw blade on the cutting saw to be embedded. The present invention has the following advantages and effects: through the cooperation of the claws, the slots and the support rod, square pipes and round pipes can be fixed separately, so that the above-mentioned cutting machine can be adapted to pipes of different shapes and diameters, achieving a high versatility.

[0004] However, when using a circular saw cutting assembly to perform straight-line cutting on bicycle frame tubes, burrs are likely to appear on the cuts of the tubes. In order to ensure the smoothness of the cut and prevent the burrs from affecting the subsequent welding of the bicycle frame, workers are usually required to perform secondary processing on the cuts of the tubes to remove the burrs. This operation is relatively cumbersome and affects the processing efficiency of the tubes. Summary of the Invention

[0005] In view of this, the present invention provides an adjustable multi-station pipe cutting device, which is provided with a grinding device and a sliding mounting seat that can automatically grind the incision of the pipe after cutting is completed. When the cutting assembly is reset after cutting is completed, as the mounting slide moves upward, the control rack drives the control gear to rotate in the opposite direction. At this time, as the control gear rotates, the transmission shaft is driven to rotate. During the rotation of the transmission shaft, the first bevel gear is driven to rotate. As the first bevel gear rotates, the second bevel gear meshed with it is driven to rotate. As the second bevel gear rotates, the control turntable is driven to rotate. During the rotation of the control turntable, the sliding mounting seat is driven to slide in the fixed slide through the control connecting rod, and the grinding device is lifted to grind the cut after cutting. The length of the control rack is just enough to drive the control turntable to rotate 360 ​​degrees. Since the control turntable can just rotate one circle, the grinding device will be retracted into the cutting workbench after grinding the cut.

[0008] Furthermore, a control ratchet is coaxially fixedly connected to each of the two control gears; two control pawls are symmetrically hinged on the outside of the transmission shaft; and the two control pawls are respectively engaged with the two control ratchets.

[0009] Furthermore, the outside of the transmission shaft is fixedly connected to multiple sets of first bevel gears; the rear parts of the multiple sets of control dials are coaxially fixedly connected to second bevel gears; and the multiple sets of second bevel gears are respectively meshed with the multiple sets of first bevel gears.

[0011] Furthermore, the bottom end surfaces of multiple groups of grinding devices are fixedly connected to sliding plates; multiple groups of sliding plates are respectively slidably connected to multiple groups of sliding mounting seats; the front end surfaces of multiple groups of sliding plates are fixedly connected to disc spring groups; the ends of multiple groups of disc spring groups are respectively fixedly connected to multiple groups of sliding mounting seats.

[0012] Furthermore, the upper parts of multiple groups of clamping seats are rotatably connected to a control rod; the outsides of multiple groups of control rods are coaxially fixedly connected to a control worm; the upper parts of multiple groups of clamping seats are rotatably connected to a control worm gear; and the multiple groups of control worm gears are respectively engaged with the multiple groups of control worm gears.

[0014] Beneficial effects

[0015] After the bicycle frame tube is cut, the present invention resets the cutting assembly. As the mounting slide moves, the control rack drives the control gear to rotate, and then the control turntable is rotated through a series of transmissions. During the rotation of the control turntable, the sliding mounting seat is driven to slide in the fixed slide through the control connecting rod, and the grinding device is lifted to grind the cut. The length of the control rack can just drive the control turntable to rotate 360 ​​degrees, so that the grinding device can be retracted into the cutting workbench after grinding the cut, so that the grinding device automatically grinds the cut of the tube to ensure the flatness of the cut. The operation is simpler and faster, and the practicality of the multi-station tube cutting device is effectively improved.

[0016] During the upward movement of the sliding mounting base, the opening and closing control protrusion presses the self-locking button switch for the first time. Since the self-locking button switch is connected to the driving part of the grinding device to form an opening and closing circuit of the grinding device, the grinding device will start at this time, so that the grinding device can be automatically opened and closed, which effectively improves the convenience of the multi-station cutting device for pipes.

[0017] The setting of the disc spring group provides pressure compensation for the grinding device, so that the grinding device can better contact with the incision, offsetting the contact force fluctuations caused by mechanism wear and changes in the thickness of the processed material. At the same time, when the grinding device encounters unexpected resistance (such as workpiece protrusions), elastic deformation is used to avoid damage to the mechanism, effectively ensuring the burr grinding effect, and also improving the safety of the multi-station pipe cutting device.

[0018] By rotating the control rod, the control rod drives the control worm to rotate, and then the sliding frame is driven to slide in the clamping seat through a series of transmissions. The spacing of the arc-shaped clamping plates is adjusted by the sliding of the sliding frame, which is convenient for positioning bicycle frame tubes of different thicknesses. The arrangement of multiple cutting components and clamping seats can perform multi-station cutting on bicycle frame tubes, effectively improving the versatility of the multi-station cutting device.

[0043] Specific usage and function of this embodiment: In the present invention, in the process of cutting the bicycle frame pipe, by starting the control motor 106, the control motor 106 drives the right lifting screw 104 to rotate, and in the process of the right lifting screw 104 rotating, the right transmission pulley 105 causes the left transmission pulley 105 to rotate through the transmission belt, and as the two transmission pulleys 105 rotate, the left lifting screw 104 is driven to rotate, and then the two lifting screws 104 are rotated at the same time, and as the lifting screw 104 rotates, the mounting slide 102 is driven. As the mounting slide 102 approaches the fixed pipe, the bicycle frame pipe is cut by starting the cutting assembly 103, and when the mounting slide 102 moves During the process, the connecting slide 115 will be driven to move, and the movement of the connecting slide 115 will drive the control rack 116 to move, and the movement of the control rack 116 will cause the control rack 116 to slowly mesh with the control gear 121. At this time, as the control rack 116 continues to move, the control gear 121 will be driven to rotate. In the process of rotation of the control gear 121, the one-way movement between the control pawl 119 and the control ratchet 120 is controlled, so that when the mounting slide 102 moves downward, the rotation of the control gear 121 will not drive the transmission shaft 118 to rotate. When the cutting is completed and the cutting assembly 103 is reset, as the mounting slide 102 moves upward, the control rack 116 will drive the control gear 121 to rotate. The wheel 121 rotates in the opposite direction. At this time, the rotation of the control gear 121 drives the transmission shaft 118 to rotate. During the rotation of the transmission shaft 118, the first bevel gear 122 is driven to rotate. As the first bevel gear 122 rotates, the second bevel gear 125 meshing with it is driven to rotate. As the second bevel gear 125 rotates, the control turntable 124 is driven to rotate. During the rotation of the control turntable 124, the sliding mounting seat 127 is driven to slide in the fixed slide 126 through the control connecting rod 129, and the grinding device 132 is lifted to grind the cut after cutting. The length of the control rack 116 can just drive the control turntable 124 to rotate 360 ​​degrees. Specifically, by calculating the control rack 116 and the control rack 116, the rotation of the second bevel gear 125 is driven to rotate. The module of the control gear 121 realizes the rotation of the control dial 124 by 360 degrees.

Since the self-locking button switch 128 is connected to the driving part of the grinding device 132 to form an opening and closing circuit of the grinding device 132, the grinding device 132 will start at this time. In the process of the sliding mounting seat 127 moving downward, the opening and closing control protrusion 131 presses the self-locking button switch 128 for the second time.The grinding device 132 is closed, and the disc spring assembly 134 provides pressure compensation to the grinding device 132, so that the grinding device 132 can better contact the incision.
