DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0019] In view of the problems existing in the prior art, an embodiment of the present invention provides a motorcycle engine gearbox gear processing device. Figure 1As shown, the motorcycle engine gearbox gear processing equipment includes a machine tool body 1, a processing platform 2 is fixedly arranged on the upper end surface of the machine tool body 1, two fastening plates 3 are slidably arranged on the processing platform 2, and the two fastening plates 3 are respectively connected to the driving ends of two first driving cylinders 5 on the sides away from each other, and the first driving cylinders 5 are fixedly arranged on the processing platform 2. The two fastening plates 3 are connected to the sides close to each other. The limit ring assembly 4 has a cavity for storing the workpiece. When working, the two fastening plates 3 move toward each other along the axial direction of the workpiece, and the workpiece will be fastened between the two fastening plates 3, and the two ends of the workpiece are respectively fixed in the two cavities. In this way, due to the limiting effect of the two limit ring assemblies 4 and the clamping and fixing effect of the two fastening plates 3, the workpiece will be firmly fixed between the two fastening plates 3, and during the rotation process, there will be no situation where the workpiece flies out.

[0020] In one embodiment, Figure 2 As shown, the motorcycle engine gearbox gear processing equipment also includes N clamping devices 6, which clamp the workpiece from the radial direction of the workpiece, and the clamping device 6 includes a second driving cylinder 61 connected to the outer ring wall of the limit ring assembly 4, and the driving end of the second driving cylinder 61 is connected to a cylinder arm 62, and the cylinder arm 62 is movably inserted in a moving hole assembly 63, and the moving hole assembly 63 is arranged on the limit ring assembly 4. The end of the cylinder arm 62 away from the second driving cylinder 61 (which can be understood as the upper end) is fixedly connected with a clamping plate 64. In order to make the equipment have a better clamping function, in an example, the clamping plate 64 is set as an arc structure. N is a positive integer greater than or equal to 2. When the number of the clamping devices 6 is two, the two clamping devices 6 are symmetrically arranged about the horizontal midline of the limit ring assembly 4.

[0021] During operation, the two fastening plates 3 move in the horizontal direction, and can clamp and fix the workpiece in the axial direction; after the workpiece is fixed between the two fastening plates 3, the second driving cylinder 61 is started, and the cylinder arm 62 carries the clamping plate 64 to move in the radial direction of the limit ring assembly 4, thereby clamping and fixing the workpiece in the radial direction. In one example, the two clamping devices 6 are in a vertical line, which can be understood as fixing the workpiece in the vertical direction. In the present invention, the workpiece can be firmly fixed on the machine tool body 1 through the limiting effect of the limit ring assembly 4, the vertical fixing effect of the two clamping devices 6, and the horizontal fixing effect of the two fastening plates 3.

[0022] It is worth noting that, since the cylinder arm 62 and the clamping plate 64 have a certain movement distance, the clamping device 6 in the equipment can be used to fix different workpieces.

[0023] In one example, in order to further improve the clamping firmness in the radial direction, the clamping device 6 can be provided in three pieces, and the three clamping devices 6 are arranged in an equidistant ring shape (not shown), or can be provided in four pieces, such as Figure 3 As shown, the four clamping devices 6 are arranged in an equidistant ring shape, so that the workpiece can be fixed from four directions. Of course, in other examples, the number of clamping devices 6 can be more.

[0024] The clamping process of the clamping device 6 is completed by the second driving cylinder 61 providing a pushing pressure to the clamping plate 64. In order to ensure that the provided pushing pressure can not only complete the clamping and fixing of the workpiece (which can be understood as a gear) through the clamping plate 64, but also avoid the situation where the pushing pressure is too large to damage the gear, in one embodiment, the motorcycle engine gearbox gear processing equipment also includes a control mechanism 7, such as Figure 3 and Figure 4 As shown, the control mechanism 7 is used to control the second driving cylinder 61 to stop providing the clamping force (which can be understood as the above-mentioned pushing pressure) when the clamping force applied by the clamping plate 64 to the workpiece is greater than or equal to a preset threshold. The control mechanism 7 includes a first mounting tube 71 embedded in the clamping plate 64, a first ejector pin 72 is movably arranged in the first mounting tube 71, the tip of the first ejector pin 72 extends out of the first mounting tube 71, and one end (which can be understood as the lower end) of the first ejector pin 72 located in the first mounting tube 71 is fixedly connected with a first electrode contact piece 74, a second electrode contact piece 75 matching the first electrode contact piece 74 is arranged in the first mounting tube 71, an elastic rod 76 is fixedly connected to the side wall of the second electrode contact piece 75, and the free end of the elastic rod 76 is fixedly connected to the inner side wall of the first mounting tube 71, and the arrangement of the elastic rod 76, when the first electrode contact piece 74 and the second electrode contact piece 75 are in contact, the elastic rod 76 has the performance of elastic deformation, so that the first electrode contact piece 74 and the second electrode contact piece 75 will still have a downward movement trend after contact, so that the damage caused by the rigid connection of the first electrode contact piece 74 and the second electrode contact piece 75 can be avoided.

[0025] During operation, as the clamping plate 64 approaches the workpiece, the first ejector pin 72 will first contact the workpiece. As the movement continues, the first ejector pin 72 will be contacted by the workpiece and move into the first mounting cylinder 71. The movement of the first ejector pin 72 will carry the first electrode contact sheet 74 toward the direction close to the second electrode contact sheet 75. When the second electrode contact sheet 75 contacts the first electrode contact sheet 74, the series circuit is connected, and the second driving cylinder 61 is controlled to stop providing driving force. At this time, the clamping plate 64 is tightly fitted to the workpiece, and the two will not move relative to each other. In this state, the clamping plate 64 can firmly fix the workpiece, and at the same time, it will not provide excessive pushing pressure to cause damage to the workpiece, for example, to prevent deformation.

[0026] In one embodiment, Figure 4 As shown, the control mechanism 7 also includes a first guiding telescopic component 73, one end (which can be understood as the upper end) of the first guiding telescopic component 73 is connected to the first ejector pin 72, and the other end (which can be understood as the lower end) of the first guiding telescopic component 73 is connected to the inner bottom wall of the first mounting cylinder 71. The setting of the first guiding telescopic component 73 can not only play a guiding and supporting role for the movement of the first ejector pin 72, so that the first ejector pin 72 can only move along the central axis of the first mounting cylinder 71, but also provide a resetting force for the resetting process of the first ejector pin 72. The first guide telescopic assembly 73 includes a first guide telescopic rod 731, a first guide telescopic tube 732 and a first guide telescopic spring 733. The first guide telescopic rod 731 is movably inserted in the first guide telescopic tube 732. The first guide telescopic spring 733 is wound and arranged outside the first guide telescopic rod 731. One end (which can be understood as the upper end) of the first guide telescopic spring 733 is fixedly connected to the side wall of the first guide telescopic rod 731, and the other end (which can be understood as the lower end) of the first guide telescopic spring 733 is fixedly connected to the outer side wall of the first guide telescopic tube 732. The first guide telescopic tube 732 is connected to the first mounting tube 71, and the first guide telescopic rod 731 is connected to the first ejector pin 72.

[0027] In one embodiment, Figure 5As shown, when the number of the clamping devices 6 is four, the four clamping devices 6 are arranged in an equidistant ring around the central axis of the limit ring assembly 4, and the four clamping devices 6 are provided with a control mechanism 7, and the four control mechanisms 7 are used to control the four clamping devices 6. The arrangement of this embodiment can not only fix the workpiece from four directions, but also achieve a firm fixation effect. At the same time, since the control mechanism 7 and the clamping device 6 are controlled one-to-one separately, the device can be used for fixing regular workpieces, such as gears, cylinders, etc., and can also be used for fixing irregular workpieces, such as pentagons.

[0028] In order to make the clamping plate 64 and the workpiece tightly contact each other, that is, to fix them together by adsorption, in one embodiment, as shown in FIG. Figure 6 As shown, the motorcycle engine gearbox gear processing equipment also includes an adsorption mechanism 8, which is used to generate a magnetic attraction when the first electrode contact sheet 74 and the second electrode contact sheet 75 are in contact, so as to adsorb the workpiece and the clamping plate 64 together. The adsorption mechanism 8 includes an electromagnet 81, and the electromagnet 81 is fixedly arranged in a second mounting cylinder 83, and the second mounting cylinder 83 is embedded in the clamping plate 64. A second ejector pin 82 is arranged in the second mounting cylinder 83, and the second ejector pin 82 is connected to the electromagnet 81. The end of the second ejector pin 82 facing the outside of the second mounting cylinder 83 (which can be understood as the upper end) is a tip structure, so as to point contact with the workpiece when in contact.

[0029] During operation, when the first electrode contact sheet 74 and the second electrode contact sheet 75 are in contact, the second ejector pin 82 and the workpiece are in contact with each other. At this time, as the series circuit is turned on when the first electrode contact sheet 74 and the second electrode contact sheet 75 are in contact, the electromagnet 81 is energized to generate magnetism. The generation of magnetic attraction will firmly fix the second ejector pin 82 and the workpiece together. The setting of this embodiment is more conducive to the fixation of irregular workpieces. Specifically, due to the particularity of irregular workpieces, different clamping plates 64 contact different parts of the same workpiece at different times. The setting of the adsorption mechanism 8 can ensure that the clamping plate 64 and the workpiece are fixed together when they are in contact and will not be separated, thereby facilitating the fixing process.

[0030] It should be noted that the settings in this example are limited to when the workpiece is made of magnetic materials, such as iron, alloy, etc.

[0031] In one embodiment, Figure 6As shown, the adsorption mechanism 8 also includes a second guide telescopic assembly 84, which is arranged between the second ejector pin 82 and the electromagnet 81, and the two ends of the second guide telescopic assembly 84 are respectively connected to the second ejector pin 82 and the electromagnet 81, and the second guide telescopic assembly 84 includes a second guide telescopic rod 841, a second guide telescopic cylinder 842, and a second guide telescopic spring 843, the second guide telescopic rod 841 is movably inserted in the second guide telescopic cylinder 842, the second guide telescopic spring 843 is wound and arranged outside the second guide telescopic rod 841, and the two ends of the second guide telescopic spring 843 are respectively fixedly connected to the side wall of the second guide telescopic rod 841 and the outer side wall of the second guide telescopic cylinder 842, the second guide telescopic rod 841 is connected to the second ejector pin 82, the second guide telescopic cylinder 842 is connected to the electromagnet 81, and the second guide telescopic assembly 84 is made of magnetic material. The setting of the second guide telescopic assembly 84 can not only play a guiding and supporting role for the movement of the second ejector pin 82, but also provide a reset force for the reset process of the second ejector pin 82.

[0032] In one embodiment, Figure 7 and Figure 8 As shown, the limiting ring assembly 4 includes a first limiting ring 41 and a second limiting ring 42, the first limiting ring 41 and the second limiting ring 42 are movably arranged with each other, and the first limiting ring 41 is fixedly arranged on the fastening plate 3, and the second limiting ring 42 is covered outside the first limiting ring 41, and the moving hole assembly 63 includes a first moving hole 631 and a second moving hole 632, the first moving hole 631 is opened on the second limiting ring 42, and the second moving hole 632 is opened on the first limiting ring 41, and the aperture size of the second moving hole 632 is larger than the aperture size of the first moving hole 631. The arrangement of this embodiment enables the device to be more suitable for irregular workpieces.

[0033] In one embodiment, Figure 8 As shown, the limiting ring assembly 4 also includes M supporting sliding assemblies, and the M supporting sliding assemblies are used to support the second limiting ring 42 so that the second limiting ring 42 can rotate around the axial center line of the first limiting ring 41, and the supporting sliding assembly includes a supporting slide groove 43, and the supporting slide groove 43 is opened on the first limiting ring 41. A supporting slider 44 is slidably arranged in the supporting slide groove 43, and one end of the supporting slider 44 located outside the supporting slide groove 43 is fixedly connected to a connecting rod 45, and the free end of the connecting rod 45 is fixedly connected to the inner ring wall of the second limiting ring 42, and M is a positive integer greater than or equal to 2.

[0034] In one embodiment, Fig. 9As shown, the motorcycle engine gearbox gear processing equipment also includes a driving mechanism 9, which is used to drive the second limit ring 42 to rotate relative to the first limit ring 41. The driving mechanism 9 includes a driving motor 91 fixed on the fastening plate 3, and the driving end of the driving motor 91 is connected to a rotating rod 92. A driving gear 93 is fixedly sleeved outside the rotating rod 92. The driving gear 93 is meshed with an arc-shaped rack 94, and the arc-shaped rack 94 is fixedly set on the outer ring wall of the second limit ring 42. The driving mechanism 9 also includes a sensor 95, which is embedded in the inner ring wall of the first limit ring 41. The number of the sensors 95 can be set to be several.

[0035] During operation, due to the structural characteristics of the irregular workpiece, the sensor 95 will find the most favorable fixing position of the workpiece by the plurality of clamping devices 6. When the plurality of clamping devices 6 are not in the most favorable fixing position, the sensor 95 will control the drive motor 91 to start, and the drive motor 91 will rotate the drive gear 93 through the rotating rod 92. The rotation of the drive gear 93 will cause the second limiting ring 42 to rotate relative to the first limiting ring 41 through the arc-shaped rack 94. The rotation of the second limiting ring 42 will cause the clamping plate 64 to move, thereby changing the positional relationship between the clamping plate 64 and the workpiece, so that the clamping plate 64 moves to the most favorable position for fixing the workpiece. When the clamping plate 64 moves to the most favorable fixing position, the sensor 95 will control the drive motor 91 to stop working.

[0036] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
