Description

Technical Field

[0001] The invention relates to the technical field of shaft part processing equipment, in particular to a shaft part surface processing equipment. Background Art

[0002] The rotor is a crucial component of the generator. One end of the rotor shaft is fitted with a slip ring that contacts the carbon brushes. Due to the high rotor speed, the roughness and finish of the slip ring directly affect contact with the carbon brushes. If the slip ring's finish doesn't meet the required level, the motor will produce noticeable noise and vibration. Polishing the slip ring is crucial; it must be perfectly round and highly coaxial with the rotor. The required coaxiality between the slip ring and the rotor is generally no more than 0.005mm.

[0003] For shaft parts with high surface coaxiality requirements, existing high-precision machining equipment can meet the requirements, but its structure is complex, manufacturing is difficult, and procurement costs are high. Therefore, it is necessary to design a surface machining equipment for shaft parts that is easy to manufacture and can ensure the coaxiality of the shaft surface and shaft height.

[0009] The rotary drive device is in transmission connection with the sleeve to drive the sleeve to rotate, and the linear drive mechanism is connected with the right slide to push the right slide to slide along the trapezoidal linear guide rail;

[0010] The surface processing mechanism is set on one side of the trapezoidal linear guide rail, and the surface processing mechanism is slidably connected to the frame along a horizontal direction perpendicular to the trapezoidal linear guide rail. The feed control mechanism is connected to the surface processing mechanism to push the surface processing mechanism to slide along the horizontal direction perpendicular to the trapezoidal linear guide rail.

[0011] Furthermore, the inner hole of the sleeve is a regular hexagonal hole.

[0012] Furthermore, the first adjustment mechanism includes a pull rod passed through the left slide to pull the first slider to slide in a direction to reduce the clearance between the first trapezoidal guide groove and the trapezoidal linear guide rail. The left slide is slidably connected to the left slide through the pull rod, and the pull rod is provided with a back-tightening nut threadedly connected to it.

[0013] Furthermore, the surface processing mechanism includes a base, a polishing wheel and a grinding motor installed on the base. The base is slidingly connected to the frame along a horizontal direction perpendicular to the trapezoidal linear guide rail. The polishing wheel is rotatably installed on the base, and the grinding motor is transmission-connected to the polishing wheel.

[0014] Furthermore, it also includes a dust collection mechanism arranged below the surface processing mechanism.

[0015] Furthermore, it also includes a surface cleaning mechanism, which is arranged on the other side of the trapezoidal linear guide rail opposite to the surface processing mechanism.

[0016] Furthermore, the surface cleaning mechanism includes a cleaning motor, a cleaning wheel, a mounting plate and a sliding drive mechanism mounted on a frame;

In addition, because the clearance between the first trapezoidal guide groove 32 and the second trapezoidal guide groove 42 and the trapezoidal linear guide rail 2 is adjustable, the requirements for the width dimension processing accuracy of the trapezoidal linear guide rail 2, the first trapezoidal guide groove 32, and the second trapezoidal guide groove 42 are reduced, making it easier to manufacture and process, and reducing its manufacturing cost.

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and examples.

[0030] like Figures 1 to 8As shown, a surface processing device for shaft parts of the present invention includes a frame 1, a surface processing mechanism 6, a left slide 3, a right slide 4, a rotation drive device 5, a linear drive mechanism 7, a feed control mechanism 8 and a trapezoidal linear guide 2 horizontally mounted on the frame 1. The left slide 3 is slidably connected to the trapezoidal linear guide 2 through a first trapezoidal guide groove 32 provided on its lower surface, and the right slide 4 is slidably connected to the trapezoidal linear guide 2 through a second trapezoidal guide groove 42 provided on its lower surface. One side surface of the first trapezoidal guide groove 32 is formed by a side surface of a first slider 33 that is slidably connected to the left slide 3 in a direction perpendicular to the side surface, so that the width of the first trapezoidal guide groove 32 and the fitting clearance with the trapezoidal linear guide 2 are adjustable. The left slide 3 is provided with a first adjustment mechanism 34 for adjusting the position of the first slider 33, thereby adjusting the fitting clearance between the first trapezoidal guide groove 32 and the trapezoidal linear guide 2. One side surface of the second trapezoidal guide groove 42 is formed by the side surface of a second slider 43 that is slidably connected to the right slide 4 in a direction perpendicular to the side surface, so that the width of the second trapezoidal guide groove 42 and the clearance with the trapezoidal linear guide rail 2 can be adjusted. The right slide 4 is provided with a second adjustment mechanism 44 for adjusting the position of the second slider 43, thereby adjusting the clearance with the second trapezoidal guide groove 42 and the trapezoidal linear guide rail 2. The left slide 3 is provided with a left centering mechanism 31 that is arranged toward the right slide 4 and whose axis is parallel to the trapezoidal linear guide rail 2. The right slide 4 is provided with a right centering mechanism 41 that is opposite to and coaxial with the left centering mechanism 31. The left slide 3 is also provided with a sleeve 45 that is rotatably connected thereto and is used to drive the shaft to rotate. The sleeve 45 is sleeved on the center of the left centering mechanism 31, and the inner hole of the sleeve 45 is a regular polygonal hole. The rotary drive device 5 is in driving connection with the sleeve 45 to drive the sleeve 45 to rotate. The linear drive mechanism 7 is connected to the right slide 4 to push the right slide 4 to slide along the trapezoidal linear guide 2. The surface processing mechanism 6 is disposed on one side of the trapezoidal linear guide 2 and is slidably connected to the frame 1 in a horizontal direction perpendicular to the trapezoidal linear guide 2. The feed control mechanism 8 is connected to the surface processing mechanism 6 to push the surface processing mechanism 6 to slide in a horizontal direction perpendicular to the trapezoidal linear guide 2.

[0031] The surface processing mechanism 6 can be a turning mechanism and / or a grinding and polishing mechanism, etc. The feed control mechanism 8 adopts the feed control structure of existing machine tools and generally includes a screw connected to and cooperating with the surface processing mechanism 6. The screw can be driven by a drive mechanism or manually. The screw can be a self-locking screw. Of course, a locking mechanism can also be provided on the frame to lock the position of the surface processing mechanism 6 to prevent its processing axis from changing position. To facilitate the understanding and control of the feed rate, the feed control structure is generally also provided with a scale for measuring the feed rate of the surface processing mechanism 6.

[0032] In the present invention, the left top mechanism 31 and the right top mechanism 41 both adopt existing top mechanisms, such as Figure 7 As shown, the top mechanism includes a top 11 and a housing 12, wherein the top is inserted into the housing and rotates with the housing.

[0033] When the surface processing equipment for shaft parts of the present invention processes the shaft surface, the linear drive mechanism 7 is used to push the right slide 4 to slide along the trapezoidal linear guide 2, causing the right slide 4 to move closer to the left slide 3. This gradually allows the tips of the left and right centering mechanisms 31 and 41 to enter the center holes at both ends of the shaft, thereby achieving centering and clamping of the shaft by cooperating with the center holes at both ends of the shaft. At the same time, the sleeve 45 is also correspondingly mounted on the end of the shaft, and its regular polygonal hole cooperates with the surface of the end of the processed shaft 13 to achieve circumferential positioning of the shaft, preventing the shaft 13 from rotating relative to the sleeve. During surface processing, the rotary drive device 5 drives the sleeve 45 to rotate, which can also drive the shaft to rotate together. The feed control mechanism 8 is used to push the surface processing mechanism 6 to slide in a horizontal direction perpendicular to the trapezoidal linear guide 2, moving it away from and closer to the shaft, thereby controlling the amount of processing performed by the surface processing mechanism 6 on the shaft surface.

[0034] It is understandable that in order to prevent the left slide 3 from moving backward when the shaft is clamped, a left slide limit block 14 should be provided on the frame 1 .

[0035] The cooperation principle between the trapezoidal linear guide rail, the first trapezoidal guide groove, and the second trapezoidal guide groove in the present invention is the same as the cooperation principle between existing trapezoidal guide rails and trapezoidal guide grooves: the trapezoidal guide grooves cooperate with the trapezoidal guide rail to limit the position of the trapezoidal guide groove components in a direction perpendicular to the trapezoidal guide rail. For example, when the trapezoidal guide rail is used, the trapezoidal guide rail can limit the position of the trapezoidal guide groove components in the vertical direction and in the horizontal direction perpendicular to the trapezoidal guide rail. The present invention slides the left slide 3 and the right slide 4 in sliding connection with the trapezoidal linear guide rail 2 through the first trapezoidal guide groove 32 and the second trapezoidal guide groove 42 on their lower surfaces, and one side surface of the first trapezoidal guide groove 32 is formed by the side surface of the first slider 33 that is slidably connected to the left slide 3 in a direction perpendicular to the side surface, and one side surface of the second trapezoidal guide groove 42 is formed by the side surface of the second slider 43 that is slidably connected to the right slide 4 in a direction perpendicular to the side surface. In this way, the left slide 3 and the right slide 4 are both positioned by the trapezoidal linear guide rail 2, and the relative positioning of the left slide 3 and the right slide 4 during the installation process is more convenient and easier to install. The left center mechanism 31 and the right center mechanism 41 are coaxially positioned, and when the left slide 3 and the right slide 4 are installed, the positions of the first slider 33 and the second slider 43 can be adjusted respectively by the first adjustment mechanism 34 and the second adjustment mechanism 44, so that the matching clearance between the first trapezoidal guide groove 32 and the second trapezoidal guide groove 42 and the trapezoidal linear guide rail 2 is as small as possible, thereby better ensuring that the left center mechanism 31 and the right center mechanism 41 are in the same position in the horizontal direction perpendicular to the trapezoidal linear guide rail 2, which is conducive to making the coaxiality of the left center mechanism 31 and the right center mechanism 41 as small as possible, thereby facilitating the high coaxiality of the machining shaft surface. In addition, because the matching clearance between the first trapezoidal guide groove 32 and the second trapezoidal guide groove 42 and the trapezoidal linear guide rail 2 is adjustable, the requirements for the width dimension processing accuracy of the trapezoidal linear guide rail 2, the first trapezoidal guide groove 32, and the second trapezoidal guide groove 42 are also reduced, making it easier to manufacture and process.

[0036] Figure 8 In the embodiment, the inner hole of the sleeve 45 is a regular hexagonal hole.

[0037] like Figure 3 、 Figure 4As shown, in the present invention, the first adjustment mechanism 34 includes a pull rod 342 that is inserted into the left slide 3 to pull the first slider 33 in a direction that reduces the clearance between the first trapezoidal guide groove 32 and the trapezoidal linear guide rail 2. The left slide 3 is slidably connected to the left slide 3 via the pull rod 342. The pull rod 342 is provided with a backing nut 341 that is threadedly connected thereto. By screwing the backing nut 341, the backing nut 341 causes the pull rod 342 to move relative to the left slide 3 along its axis, thereby pulling the first slider 33 in a direction that reduces the clearance between the first trapezoidal guide groove 32 and the trapezoidal linear guide rail 2, thereby adjusting the clearance between the first trapezoidal guide groove 32 and the trapezoidal linear guide rail 2. In the above structure, the pull rod also serves as a sliding guide for the first slider, resulting in a simpler structure. In this embodiment of the present invention, the second adjustment mechanism 44 adopts the same structure as the first adjustment mechanism 34 and will not be further described here.

[0038] like Figure 9 As shown, in this embodiment of the present invention, the surface processing mechanism 6 is a grinding mechanism, comprising a base 61, a polishing wheel 63, and a grinding motor 62 mounted on the base 61. The base 61 is slidably connected to the frame 1 in a horizontal direction perpendicular to the trapezoidal linear guide 2. The polishing wheel 63 is rotatably mounted on the base 61, and the grinding motor 62 is transmission-connected to the polishing wheel 63. The grinding motor 62 can be transmission-connected to the polishing wheel 63 via a common transmission mechanism such as a belt or chain.

[0039] like Figure 1 As shown, the present invention is provided with a dust collecting mechanism 10 below the surface processing mechanism 6. The dust collecting mechanism 10 can absorb dust, debris, etc. generated during processing, and especially when the surface processing mechanism 6 is a grinding mechanism, the dust collecting mechanism 10 can better avoid environmental pollution.

[0040] The present invention is further provided with a surface cleaning mechanism 9, which is arranged on the other side of the trapezoidal linear guide 2 opposite to the surface processing mechanism 6. The surface cleaning mechanism 9 can clean the surface of the shaft after surface processing to prevent it from adhering to the shaft surface and affecting the quality of the shaft surface processing.

[0041] The surface cleaning mechanism 9 may be a flushing cleaning mechanism. Figure 9As shown, the surface cleaning mechanism 9 includes a cleaning motor 92, a cleaning wheel 93, a mounting plate 91, and a sliding drive mechanism 94 mounted on the frame 1. The mounting plate 91 is slidably connected to the frame 1 in a horizontal direction perpendicular to the trapezoidal linear guide 2, the cleaning wheel 93 is rotatably mounted on the mounting plate 91, the cleaning motor 92 is mounted on the mounting plate 91 and is in transmission connection with the cleaning wheel 93, and the sliding drive mechanism 94 is connected to the mounting plate 91 to drive the mounting plate 91 to slide along the horizontal direction perpendicular to the trapezoidal linear guide 2 with the frame 1.

[0042] When the shaft surface is processed, the sliding drive mechanism 94 drives the mounting plate 91 to slide, so that the cleaning wheel 93 contacts the processing shaft surface, and the cleaning motor 92 is started. The cleaning motor 92 drives the cleaning wheel 93 to rotate, and the cleaning wheel 93 can be used to clean the shaft surface in time.

[0043] In the present invention, the sliding drive mechanism 94 and the linear drive mechanism 7 are generally pneumatic cylinders or hydraulic cylinders, and the rotation drive device 5 is generally a motor.
