Description

Technical Field

[0001] The invention relates to the technical field of vehicle center shaft processing, in particular to a center shaft processing device for an electric motorcycle. Background Art

[0002] The motorcycle's center shaft, also known as the motorcycle fork shaft, is an important component on the motorcycle frame. The center shaft is located at the connection between the motorcycle frame and the fork. Its main function is to connect the frame and the rear fork so that the rear fork can rotate around the center shaft, thereby realizing the rear suspension function of the motorcycle. When the motorcycle is driving on an uneven road, the rear suspension system buffers the impact from the ground by the rotation of the center shaft to ensure the stability and comfort of riding. It is generally made of high-strength metal materials such as steel or aluminum alloy. It is usually a cylindrical shaft with both ends connected to the frame and rear fork by bolts or other fixing methods. The diameter and length of the center shaft will vary depending on the model and design requirements of the motorcycle. On some high-performance motorcycles, the center shaft may adopt a more complex structure, such as with bearings or shock absorbers, to improve the performance of the suspension system.

[0003] At present, the middle axis of an electric motorcycle is sawed during processing. The saw blade on the existing sawing machine will fix the middle axis by a clamp before sawing. Generally, the middle axis is fixed by synchronous movement of the lateral and upper clamps. This will lead to the problem of center point offset of the middle axis when fixing middle axes of different sizes. During sawing, the saw blade cuts the middle axis by lateral movement. Generally, the height of the saw blade is fixed. This will result in the saw blade being unable to perform axis-aligned sawing for middle axes of different sizes. The eccentric sawing method will increase the sawing pressure of the saw blade, thereby affecting the service life of the saw blade. In view of this, we propose an electric motorcycle middle axis processing device. Summary of the invention

[0013] It can be seen from the above technical solutions that the electric motorcycle middle shaft processing device provided in the embodiments of this specification has at least the following beneficial effects:

[0014] (1) The present invention drives the dynamic sawing device as a whole to perform mobile sawing through a control device, and utilizes the moving force to first drive the annular sleeve to rotate, so that the positioning fixture can adaptively and elastically clamp the central axis, and automatically clamp and position the central axis according to the size of the central axis, thereby reducing the pressure problem of the saw blade and increasing the service life of the saw blade. The control device uses its own structure to reinforce the annular sleeve to achieve the effect of stabilizing the angle of the annular sleeve, further achieving the effect of stably clamping the clamp during sawing, and then utilizes the moving force to drive the dynamic sawing device to perform wave-type sawing, thereby further achieving the purpose of improving the sawing effect.

[0015] (2) In the present invention, the torsion spring is arranged on the annular sleeve, and the clamp is in an elastic clamping state, so that the clamp can automatically clamp and position the central axis according to the size of the central axis. The elastic force of the torsion spring is greater than the gravity of the central axis itself, so the clamp can position the central axis to the axis center of the annular sleeve, further achieving the effect of axis center fixed point positioning and clamping of central axes of different sizes. The clamp and the corresponding sliding shaft and other structures are distributed in a circular array on the fixed base in an offset manner, so that there is no size restriction between the clamps, so the clamping range of the clamp can be further increased, and the size diversity of the central axis processing can be further increased.

[0016] (3) The present invention uses a reinforcement device. Before the saw blade disc starts sawing, the moving sleeve that continues to move will drive the spring telescopic tube on the extrusion block to move through the limiting sleeve thereon. When the spring telescopic tube contacts the socket, the spring telescopic tube drives the socket to move toward the arc-shaped plug-in shaft, thereby fixing the arc-shaped plug-in shaft during the plug-in period, and then utilizing the arc-shaped plug-in shaft to achieve a secondary fixation effect on the annular sleeve. Utilizing the secondary reinforcement of the socket, the angle of the annular sleeve is stabilized, thereby further achieving an effect of stable clamping of the splint during sawing.

[0017] (4) When the saw blade moves to saw, the positioning shaft on the telescopic seat will slide to the fluctuation zone of the fluctuation slide. Restricted by the fluctuation slide, the positioning shaft will shake up and down in a short range in the fluctuation slide. During the shaking, the positioning shaft drives the saw blade as a whole to perform fluctuation sawing through the telescopic seat, thereby further achieving the purpose of improving the sawing effect. The output shaft of the sawing motor drives the saw blade on the key shaft to rotate by rotating the sleeve rod, and the saw blade achieves the sawing effect during high-speed rotation. The saw blade moves and cuts with respect to the axis clamped by the alignment splint, thereby achieving the effect of the sawing center always acting at the center of the central axis, thereby avoiding the eccentric sawing method that increases the sawing pressure of the saw blade and improves the service life of the saw blade.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1 - Fig.10 As shown, an electric motorcycle center shaft processing device includes a machine base 1; a fixed base 2, the fixed base 2 is fixedly installed on the machine base 1, the fixed base 2 is elastically connected to an annular jacket 3 through a torsion spring, the end of the annular jacket 3 is rotatably connected to the fixed base 2, a plurality of inclined side top plates 4 distributed in a circular array are fixedly connected inside the annular jacket 3, and a positioning fixture 5 is arranged on the fixed base 2; a control device 6, the control device 6 is arranged on the machine base 1; and a dynamic sawing device 7, the dynamic sawing device 7 is arranged on the control device 6.

[0033] In this embodiment, the positioning fixture 5 includes a sliding shaft 51, the surface of the sliding shaft 51 is slidably connected to the interior of the fixed base 2 (such as Figure 3 and Fig.10 As shown in the figure, one end of the sliding shaft 51 is fixedly connected to a clamping plate 52, and the other end of the sliding shaft 51 is rotatably connected to a top wheel 53. The number and position of the sliding shaft 51, the clamping plate 52 and the top wheel 53 correspond to each other with respect to the inclined top plate 4. A spring telescopic rod 54 is fixedly connected between the surface of the clamping plate 52 and the surface of the fixed base 2. The spring telescopic rod 54 is composed of two telescopic rods. A spring is connected between the insides of the two rods for linearly limiting the clamping plate 52 and providing elastic power for the clamping plate 52. In the initial state (i.e. Figure 1As shown), the spring telescopic rod 54 is in a retracted state, and the surface of the top wheel 53 is connected to the surface of the inclined side top plate 4.

[0034] In the initial state, the annular jacket 3 is fixed by the structure inside the control device 6. At this time, the torsion spring on the annular jacket 3 is in a compressed state. When the annular jacket 3 loses its limit, the elastic force of the torsion spring provides the annular jacket 3 with rotational power. During the rotation, the annular jacket 3 squeezes the top wheel 53 through the multiple inclined side top plates 4 distributed in the internal circular array. Since the sliding shaft 51 is restricted by the spring telescopic rod 54 and can only move linearly on the inner wall of the circular groove of the fixed base 2, the top wheel 53 will transmit power to the clamping plate 52 on the sliding shaft 51 after being compressed. The clamping plates 52 corresponding to the inclined side top plates 4 distributed in the circular array move synchronously toward the axis of the annular jacket 3. During the movement, the clamping plates 52 realize the rotation of the inner wall of the circular groove. The effect of clamping and positioning the central axis is achieved. Due to the torsion spring arranged on the annular sleeve 3, the clamping plate 52 is in an elastic clamping state, so that the clamping plate 52 can automatically clamp and position the central axis according to the size of the central axis. The elastic force of the torsion spring is greater than the gravity of the central axis itself, so the clamping plate 52 can position the central axis to the axis center of the annular sleeve 3, and further achieve the effect of axial fixed-point positioning and clamping of central axes of different sizes. The clamping plate 52 and the corresponding sliding shaft 51 and other structures are distributed in a circular array on the fixed base 2 in an offset manner, so that there is no size restriction between each clamping plate 52, so that the clamping range of the clamping plate 52 can be further increased, and the size diversity of the central axis processing can be further increased.

[0035] Furthermore, the control device 6 includes an active motor 61, one end of which is installed on one side of the machine base 1, and the output shaft of the active motor 61 is connected to a positioning screw 62, the end of which is rotatably connected to the machine base 1, the surface of the positioning screw 62 is threadedly connected to a movable sleeve 63, the movable sleeve 63 is fixedly connected to a connecting arm 64, the surface of the connecting arm 64 contacts a passive plate 65, the end of the passive plate 65 is fixedly connected to the annular sleeve 3, the end of the movable sleeve 63 is rotatably connected to an adjusting screw 66, the movable sleeve 63 is fixedly connected to a limiting sleeve 67, the number of the positioning screws 62 is set to two, and the two positioning screws 62 are symmetrically distributed with each other, and the ends of the two positioning screws 62 are transmission connected through a transmission device (such as Figure 1As shown), it is used to increase the overall stability of the dynamic sawing device 7. By starting the active motor 61, the output shaft of the active motor 61 drives the positioning screw 62 to rotate to achieve the effect of driving the moving sleeve 63 to move as a whole, and the moving sleeve 63 moves toward the axis of the annular jacket 3 as a whole. During the movement, the moving sleeve 63 drives the connecting arm 64 to move synchronously. The connecting arm 64 positions and restricts the passive plate 65 in the initial state. When the connecting arm 64 is away from the passive plate 65, the passive plate 65 is reset and rotated by the elastic force of the torsion spring on the annular jacket 3, and the annular jacket 3 rotates counterclockwise as a whole. During the rotation, the annular jacket 3 realizes the positioning of the center axis through the positioning fixture 5.

[0036] Furthermore, the control device 6 also includes a reinforcement device 68, which includes an extrusion block 681, a limit frame 683 and an arc-shaped plug shaft 685. One side of the extrusion block 681 is fixedly connected to the limit shaft sleeve 67. The extrusion block 681 is fixedly connected to a spring telescopic tube 682. The spring telescopic tube 682 is composed of two telescopic tubes. Springs are arranged in the two tubes. The interior of the limit frame 683 is elastically connected to a socket 684 through a spring. The elastic force of the spring in the spring telescopic tube 682 is greater than the elastic force of the spring on the socket 684, thereby ensuring that the spring telescopic tube 682 can drive the socket 684 to move during movement. The surface of the limit frame 683 is fixedly connected to the surface of the fixed base 2. The surface of the seat 684 is slidably connected to the inner wall of the limit frame 683, the surface of the arc-shaped plug shaft 685 is fixedly connected to the surface of the annular sleeve 3, and a plurality of plug shafts distributed in a circular array are arranged on the arc-shaped plug shaft 685. The annular sleeve 3 can rotate at different angles according to the central axis of different sizes. The rotation angle of the annular sleeve 3 corresponds to the position and number of the plug shaft distribution. The central axis sizes are set to X1, X2, and X3 respectively, and the rotation angle values ​​of the annular sleeve 3 are Y1, Y2, and Y3 respectively. At this angle, the distribution angle of the plug shaft at the arc-shaped plug shaft 685 on the annular sleeve 3 is also Y1, Y2, and Y3. The socket 684 can plug and fix the corresponding plug shafts at the Y1, Y2, and Y3 angles.

[0037] Before the dynamic sawing device 7 saws, the moving sleeve 63 that continues to move will drive the spring telescopic tube 682 on the extrusion block 681 to move through the limit sleeve 67 on it. When the spring telescopic tube 682 contacts the socket 684, the spring telescopic tube 682 drives the socket 684 to move toward the arc plug shaft 685 until the socket 684 is plugged into the plug shaft on the arc plug shaft 685. Since the socket 684 is restricted by the limit frame 683 and can only move in a straight line, the socket 684 will move during the plugging process. The arc-shaped plug shaft 685 is fixed, and then the arc-shaped plug shaft 685 is used to achieve the effect of secondary fixing of the annular jacket 3. Since the annular jacket 3 previously used the torsion spring force to elastically position the multiple clamps 52, when the middle axis is sawed during the elastic positioning period, the strong cutting force will cause the middle axis to be misaligned, thereby affecting the processing accuracy. Therefore, the secondary reinforcement of the socket 684 is used to achieve the effect of stabilizing the angle of the annular jacket 3, and further achieve the effect of stable clamping of the clamps 52 during sawing. At the same time, by setting a retractable spring telescopic tube 682, while ensuring the movement of the socket 684, it can automatically give way in the subsequent movement of the limiting shaft sleeve 67, thereby ensuring that the dynamic sawing device 7 always has the effect of retractably positioning the socket 684 when sawing the middle axis.

[0038] Example 1

[0039] Based on Example 1, an electric motorcycle middle shaft processing device, see Figure 1 - Fig. 9 As shown, the dynamic sawing device 7 includes a screw sleeve base 71, the inner wall of the screw sleeve base 71 is threadedly connected to the surface of the adjusting screw 66, a sawing motor 72 is installed inside the screw sleeve base 71, the output shaft of the sawing motor 72 is connected to a rotating sleeve rod 73, the end of the rotating sleeve rod 73 is slidably connected to a key shaft 74, the arrangement of the rotating sleeve rod 73 and the key shaft 74 enables the rotating sleeve rod 73 and the key shaft 74 to be able to telescope while maintaining the transmission effect of force, the end of the key shaft 74 is fixedly connected to a bevel gear 1 75, the surface of the bevel gear 1 75 is meshed with a bevel gear 2 76, the end of the bevel gear 2 76 is fixedly connected to a saw blade 77, the end of the saw blade 77 is rotatably connected to a telescopic seat 78, and the top of the telescopic seat 78 is internally slidably connected to a fixed seat 79 (as shown in FIG. Figure 7The fixing seat 79 is fixed on the screw sleeve base 71, the rotating sleeve rod 73 rotates in the fixing seat 79, the key shaft 74 rotates in the telescopic seat 78, the telescopic seat 78 is slidably connected to the fixing seat 79, the key shaft 74 is slidably connected in the rotating sleeve rod 73, and the output shaft of the sawing motor 72 drives the bevel gear 1 75 on the key shaft 74 to mesh with the bevel gear 2 76 on the sawing disc 77 to rotate, and the sawing disc 77 realizes the sawing effect during high-speed rotation, and the sawing disc 77 moves and cuts with the axis clamped by the clamping plate 52, so as to achieve the effect of the sawing center always acting at the center of the central axis, thereby avoiding the eccentric sawing method to increase the sawing pressure of the saw blade, thereby affecting the service life of the saw blade, thereby reducing the pressure of the sawing disc 77 and improving the service life of the sawing disc 77.

[0040] In addition, the surface of the fixed seat 79 is fixedly connected to the surface of the screw sleeve base 71, the surface of the rotating sleeve rod 73 is rotatably connected inside the fixed seat 79, the surface of the key shaft 74 is rotatably connected inside the telescopic seat 78, and a limiting sleeve 781 is fixedly connected to the screw sleeve base 71. The limiting sleeve 781 is slidably sleeved on the limiting shaft sleeve 67. By setting the limiting sleeve 781 to slide on the limiting shaft sleeve 67, the effect of limiting the screw sleeve base 71 as a whole is achieved. When the position of the saw blade 77 needs to be adjusted, the operator drives the adjusting screw 66 to rotate by rotating the handle. When the adjusting screw 66 rotates, it can drive the saw blade 77 as a whole to adjust its position through the screw sleeve base 71.

[0041] In addition, the dynamic sawing device 7 also includes a limit rod 712, both ends of which are fixedly connected to the machine base 1, and a wave slide 711 is slidably connected to the limit rod 712. The wave slide 711 is provided with a horizontal area and a wave area, and the inner wall of the wave slide 711 is slidably connected to a positioning shaft 710, and the positioning shaft 710 is fixedly connected to one side of the telescopic seat 78. When the saw blade 77 moves for sawing, the positioning shaft 710 on the telescopic seat 78 will slide to the wave area of ​​the wave slide 711. Restricted by the wave slide 711, the positioning shaft 710 performs a short range of up and down shaking in the wave slide 711. During the shaking period, the positioning shaft 710 drives the saw blade 77 as a whole to perform wave-like sawing through the telescopic seat 78, thereby further achieving the purpose of improving the sawing effect.

[0042] When the electric motorcycle middle shaft processing device of the present invention is in use, the middle shaft to be processed is placed in the circular groove in the fixed base 2, and the active motor 61 is started. The output shaft of the active motor 61 drives the positioning screw 62 to rotate to achieve the effect of driving the movable sleeve 63 to move as a whole. The movable sleeve 63 moves toward the axis of the annular jacket 3 as a whole. During the movement, the movable sleeve 63 drives the connecting arm rod 64 to move synchronously. The connecting arm rod 64 performs positioning restriction on the passive plate 65 in the initial state. When the connecting arm rod 64 is away from the passive plate 65, the passive plate 65 is reset and rotated by the elastic force of the torsion spring on the annular jacket 3, and the annular jacket 3 rotates counterclockwise as a whole. During the rotation, the annular jacket 3 squeezes the top wheel 53 through the multiple inclined side top plates 4 distributed in the internal circular array. Since the sliding shaft 51 is restricted by the spring telescopic rod 54 and can only move linearly on the inner wall of the circular groove of the fixed base 2, the top wheel 53 will be pressed after being pressed. The power is transmitted to the clamping plate 52 on the sliding shaft 51, and multiple clamping plates 52 distributed in a circular array and corresponding to the inclined side top plate 4 move synchronously toward the axis center of the annular sleeve 3. During the movement, the clamping plate 52 achieves the effect of clamping and positioning the central axis in the circular groove. At the same time, due to the torsion spring arranged on the annular sleeve 3, the clamping plate 52 is in an elastic clamping state, so that the clamping plate 52 can automatically clamp and position the central axis according to the size of the central axis. The elastic force of the torsion spring is greater than the gravity of the central axis itself, so the clamping plate 52 can position the central axis to the axis center of the annular sleeve 3, further achieving the effect of axis center fixed point positioning and clamping of the central axis at different sizes. The clamping plate 52 and the corresponding sliding shaft 51 and other structures are distributed in a circular array on the fixed base 2 in a staggered manner, so that there is no size restriction between each clamping plate 52, so the clamping range of the clamping plate 52 can be further increased, and the size diversity of the central axis processing can be further increased. Before the saw blade 77 starts sawing, the moving sleeve 63 that continues to move will drive the spring expansion tube 682 on the extrusion block 681 to move through the limiting sleeve 67 thereon. When the spring expansion tube 682 contacts the socket 684, the spring expansion tube 682 drives the socket 684 to move toward the arc plug shaft 685 until the socket 684 is plugged into the shaft on the arc plug shaft 685. Since the socket 684 is restricted by the limiting frame 683 at this time and can only move in a straight line, the socket 684 will fix the arc plug shaft 685 during the plugging period, and then use the arc plug shaft 685 to achieve the effect of secondary fixation of the annular sleeve 3. Since the previous annular sleeve 3 uses the elastic force of the torsion spring to elastically position multiple clamps 52, when the middle axis is sawing during the elastic positioning period, the strong cutting force will cause the middle axis to be misaligned, thereby affecting the processing accuracy. Therefore, the secondary reinforcement of the socket 684 is used to achieve the effect of stabilizing the angle of the annular sleeve 3, and further achieve the effect of stable clamping of the clamps 52 during sawing.

[0043] After the clamping plate 52 is reinforced for the second time, the active motor 61 that continues to work drives the moving shaft sleeve 63 to continue to move, and the sawing motor 72 is started in advance. The output shaft of the sawing motor 72 drives the bevel gear 1 75 on the key shaft 74 to mesh with the bevel gear 2 76 to rotate. The sawing disc 77 achieves the sawing effect during the high-speed rotation. The sawing disc 77 moves and cuts with the axis clamped by the clamping plate 52, so as to achieve the effect of the sawing center always acting at the center of the central axis, thereby avoiding the eccentric sawing method to increase the sawing of the saw blade The problem of pressure, which affects the service life of the saw blade, is achieved by reducing the pressure on the saw blade disc 77 and increasing the service life of the saw blade disc 77. At the same time, when the saw blade disc 77 moves to the circular groove area, the positioning shaft 710 on the telescopic seat 78 will slide to the fluctuation area of ​​the fluctuation slide seat 711. Restricted by the fluctuation slide seat 711, the positioning shaft 710 performs a short range of up and down shaking in the fluctuation slide seat 711. During the shaking period, the positioning shaft 710 drives the saw blade disc 77 as a whole to perform fluctuation sawing through the telescopic seat 78, thereby further achieving the purpose of improving the sawing effect.
