Description

Technical Field

[0001] This utility model relates to the technical field of shaft parts processing equipment, specifically a surface processing equipment for shaft parts. Background Technology

[0002] The rotor is a crucial component of the generator, with slip rings at one end of the rotor shaft that contact the carbon brushes. Due to the high rotor speed, the roughness and smoothness of the slip rings directly affect the contact with the carbon brushes. If the slip rings do not meet the required smoothness, the motor will produce significant noise and vibration. The polishing process of the slip rings is a critical step, requiring a high degree of roundness after polishing, as well as a high degree of coaxiality between the slip rings and the rotor. The coaxiality requirement between the slip rings and the rotor is generally no more than 0.005 mm.

[0003] For shaft parts requiring high surface coaxiality, existing high-precision machining equipment can meet the requirements, but its structure is complex, difficult to manufacture, and has high procurement costs. Therefore, it is necessary to design a surface machining equipment for shaft parts that is easy to manufacture and can easily ensure the coaxiality between the shaft surface and the shaft height. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a surface processing equipment for shaft parts that is easy to manufacture and can ensure the coaxiality of the shaft surface and shaft height.

[0006] The left slide block is slidably connected to the trapezoidal linear guide rail via a first trapezoidal guide groove on its lower surface, and the right slide block is slidably connected to the trapezoidal linear guide rail via a second trapezoidal guide groove on its lower surface.

[0007] One side of the first trapezoidal guide groove is formed by the side of a first slider that is slidably connected to the left slide block in a direction perpendicular to that side. The left slide block is provided with a first adjustment mechanism for adjusting the position of the first slider, thereby adjusting the clearance between the first trapezoidal guide groove and the trapezoidal linear guide rail. One side of the second trapezoidal guide groove is formed by the side of a second slider that is slidably connected to the right slide block in a direction perpendicular to that side. The right slide block is provided with a second adjustment mechanism for adjusting the position of the second slider, thereby adjusting the clearance between the second trapezoidal guide groove and the trapezoidal linear guide rail.

[0008] A left center mechanism is installed on the left slide block and is positioned toward the right slide block with its axis parallel to the trapezoidal linear guide rail. A right center mechanism is installed on the right slide block and is opposite to and coaxial with the left center mechanism. The left slide block is also provided with a sleeve for driving the shaft to rotate, which is rotatably connected to the left center mechanism. The sleeve is fitted onto the center of the left center mechanism, and the inner hole of the sleeve is a regular polygonal hole.

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

[0010] The surface processing mechanism is located on one side of the trapezoidal linear guide rail. The surface processing mechanism is slidably connected to the frame along the 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 that passes through the left slide block to pull the first slider along a direction that reduces the gap between the first trapezoidal guide groove and the trapezoidal linear guide rail. The left slide block is slidably connected to the pull rod, and the pull rod is provided with a back tightening nut that is threadedly connected to it.

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

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

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

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

[0017] The mounting plate is slidably connected to the frame along the horizontal direction perpendicular to the trapezoidal linear guide rail. The cleaning brush is rotatably mounted on the mounting plate. The cleaning motor is mounted on the mounting plate and is connected to the cleaning brush in a transmission manner. The sliding drive mechanism is connected to the mounting plate to drive the mounting plate to slide along the horizontal direction perpendicular to the trapezoidal linear guide rail and the frame.

[0018] The beneficial effects of this utility model are as follows: In this surface processing equipment for shaft parts, the left slide block 3 and the right slide block 4 are slidably connected to the trapezoidal linear guide rail 2 via the first trapezoidal guide groove 32 and the second trapezoidal guide groove 42 on their lower surfaces, respectively. One side of the first trapezoidal guide groove 32 is formed by the side of the first slider 33, which is slidably connected to the left slide block 3 in a direction perpendicular to that side. Similarly, one side of the second trapezoidal guide groove 42 is formed by the side of the second slider 43, which is slidably connected to the right slide block 4 in a direction perpendicular to that side. Thus, in… When installing the left slide block 3 and the right slide block 4, the positions of the first slider 33 and the second slider 43 can be adjusted by the first adjustment mechanism 34 and the second adjustment mechanism 44, respectively, so that the fit clearance between the first trapezoidal guide groove 32 and the second trapezoidal guide groove 42 and the trapezoidal linear guide rail 2 is minimized. This ensures 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 helps to minimize the coaxiality between the left center mechanism 31 and the right center mechanism 41, thereby facilitating the high coaxiality of the machined shaft surface. In addition, because the fit 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 machining accuracy of the trapezoidal linear guide rail 2, the first trapezoidal guide groove 32, and the second trapezoidal guide groove 42 are reduced, making them easier to manufacture and reducing manufacturing costs.

Detailed Implementation

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

[0030] like Figures 1 to 8As shown, this utility model discloses a surface processing device for shaft parts, comprising a frame 1, a surface processing mechanism 6, a left slide block 3, a right slide block 4, a rotary drive device 5, a linear drive mechanism 7, a feed control mechanism 8, and a trapezoidal linear guide rail 2 horizontally mounted on the frame 1. The left slide block 3 is slidably connected to the trapezoidal linear guide rail 2 via a first trapezoidal guide groove 32 on its lower surface, and the right slide block 4 is slidably connected to the trapezoidal linear guide rail 2 via a second trapezoidal guide groove 42 on its lower surface. One side of the first trapezoidal guide groove 32 is formed by the side of a first slider 33 that is slidably connected to the left slide block 3 in a direction perpendicular to that side, making the width of the first trapezoidal guide groove 32 and the clearance between it and the trapezoidal linear guide rail 2 adjustable. The left slide block 3 is provided with a first adjustment mechanism 34 for adjusting the position of the first slider 33, thereby adjusting the clearance between the first trapezoidal guide groove 32 and the trapezoidal linear guide rail 2. One side of the second trapezoidal guide groove 42 is formed by the side of the second slider 43, which is slidably connected to the right slide block 4 in a direction perpendicular to that side, making the width of the second trapezoidal guide groove 42 and the clearance between it and the trapezoidal linear guide rail 2 adjustable. The right slide block 4 is provided with a second adjustment mechanism 44 for adjusting the position of the second slider 43, thereby adjusting the clearance between the second trapezoidal guide groove 42 and the trapezoidal linear guide rail 2. The left slide block 3 is equipped with a left tip mechanism 31 that is positioned toward the right slide block 4 and whose axis is parallel to the trapezoidal linear guide rail 2. The right slide block 4 is equipped with a right tip mechanism 41 that is opposite to and coaxial with the left tip mechanism 31. The left slide block 3 is also provided with a sleeve 45 for driving shaft rotation that is rotatably connected to it. The sleeve 45 is fitted onto the tip of the left tip mechanism 31, and the inner hole of the sleeve 45 is a regular polygonal hole. The rotary drive device 5 is connected to the sleeve 45 to drive the sleeve 45 to rotate. The linear drive mechanism 7 is connected to the right slide block 4 to push the right slide block 4 to slide along the trapezoidal linear guide rail 2. The surface processing mechanism 6 is located on one side of the trapezoidal linear guide rail 2. The surface processing mechanism 6 is slidably connected to the frame 1 in a horizontal direction perpendicular to the trapezoidal linear guide rail 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 rail 2.

[0031] The surface finishing mechanism 6 can be a turning mechanism and / or a grinding and polishing mechanism, etc. The feed control mechanism 8 adopts an existing feed control structure on the machine tool, generally including a lead screw that connects and cooperates with the surface finishing mechanism 6. The lead screw can be driven by a drive mechanism or manually. The lead screw can be a self-locking lead screw. Alternatively, a locking mechanism can be installed on the machine frame to lock the position of the surface finishing mechanism 6, preventing its machining axis from shifting. To facilitate understanding and control of the feed amount, the feed control structure generally also has a scale for measuring the feed amount of the surface finishing mechanism 6.

[0032] In this utility model, both the left tip mechanism 31 and the right tip mechanism 41 adopt existing tip mechanisms, such as... Figure 7 As shown, the tip mechanism includes a tip 11 and an outer casing 12. The tip is inserted into the outer casing and rotates in conjunction with the outer casing.

[0033] When machining the shaft surface of this utility model, the linear drive mechanism 7 pushes 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 center mechanisms 31 and 41 to enter the center holes at both ends of the shaft, thus achieving centering and clamping fixation of the shaft by engaging with the center holes at both ends. Simultaneously, the sleeve 45 is also fitted onto the end of the shaft, and its polygonal hole engages with the surface of the end of the shaft 13 being machined to achieve circumferential limiting of the shaft, preventing the shaft 13 from rotating relative to the sleeve. During surface machining, the rotary drive device 5 drives the sleeve 45 to rotate, which in turn rotates the shaft. The feed control mechanism 8 pushes the surface machining mechanism 6 to slide horizontally along the trapezoidal linear guide 2, moving it away from and closer to the shaft, thereby controlling the amount of machining performed on the shaft surface by the surface machining mechanism 6.

[0034] Understandably, in order to prevent the left slide block 3 from moving backward when clamping the shaft, a left slide block limit block 14 should be installed 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 this invention is the same as the existing cooperation principle between trapezoidal guide rail and trapezoidal guide groove: the trapezoidal guide groove component is limited in the direction perpendicular to the trapezoidal guide rail by cooperating with the trapezoidal guide rail. For example, when the trapezoidal guide rail is used, it can limit the trapezoidal guide groove component in the vertical direction and in the horizontal direction perpendicular to the trapezoidal guide rail. This invention slidably connects the left slide block 3 and the right slide block 4 to the trapezoidal linear guide rail 2 via a first trapezoidal guide groove 32 and a second trapezoidal guide groove 42 on their lower surfaces, respectively. One side of the first trapezoidal guide groove 32 is formed by the side of a first slider 33 that is slidably connected to the left slide block 3 in a direction perpendicular to that side. Similarly, one side of the second trapezoidal guide groove 42 is formed by the side of a second slider 43 that is slidably connected to the right slide block 4 in a direction perpendicular to that side. Thus, both the left slide block 3 and the right slide block 4 are positioned by the trapezoidal linear guide rail 2, making their relative positioning during installation more convenient and efficient. This design facilitates coaxial positioning of the left and right center mechanisms 31 and 41. Furthermore, during the installation of the left and right slide blocks 3 and 4, the positions of the first and second sliders 33 and 43 can be adjusted via the first and second adjustment mechanisms 34, respectively. This minimizes the clearance between the first and second trapezoidal guide grooves 32 and 42 and the trapezoidal linear guide rail 2, ensuring that the left and right center mechanisms 31 and 41 are aligned horizontally perpendicular to the trapezoidal linear guide rail 2. This minimizes the coaxiality of the left and right center mechanisms 31 and 41, thereby ensuring high coaxiality of the machined shaft surface. Additionally, the adjustable clearance between the first and second trapezoidal guide grooves 32 and 42 and the trapezoidal linear guide rail 2 reduces the precision requirements for the width dimensions of the trapezoidal linear guide rail 2, the first trapezoidal guide groove 32, and the second trapezoidal guide groove 42, making manufacturing easier.

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

[0037] like Figure 3 , Figure 4As shown, in this utility model, the first adjusting mechanism 34 includes a pull rod 342 passing through the left slide block 3 to pull the first slider 33 along a direction that reduces the clearance between the first trapezoidal guide groove 32 and the trapezoidal linear guide rail 2. The left slide block 3 is slidably connected to the pull rod 342, and a back-tightening nut 341 is threadedly connected to the pull rod 342. Tightening the back-tightening nut 341 allows the pull rod 342 to move relative to it along its axial direction, thereby pulling the first slider 33 along a direction that reduces the clearance between the first trapezoidal guide groove 32 and the trapezoidal linear guide rail 2, thus 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 the sliding guide rail for the first slider, making the structure simpler. In this embodiment of the utility model, the second adjusting mechanism 44 adopts the same structure as the first adjusting mechanism 34, which will not be described in detail here.

[0038] like Figure 9 As shown in this embodiment of the present invention, the surface processing mechanism 6 is a grinding mechanism, including 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 along a horizontal direction perpendicular to the trapezoidal linear guide rail 2. The polishing wheel 63 is rotatably mounted on the base 61, and the grinding motor 62 is drive-connected to the polishing wheel 63. Specifically, the grinding motor 62 can be drive-connected to the polishing wheel 63 through common transmission mechanisms such as belts or chains.

[0039] like Figure 1 As shown, the present invention includes a dust collection mechanism 10 located below the surface processing mechanism 6. The dust collection mechanism 10 can absorb dust, debris, and other contaminants generated during processing. In particular, when the surface processing mechanism 6 is a grinding mechanism, the dust collection mechanism 10 can better prevent environmental pollution.

[0040] This invention also includes a surface cleaning mechanism 9, which is located on the opposite side of the trapezoidal linear guide 2 and the surface processing mechanism 6. The surface cleaning mechanism 9 can clean the surface of the shaft after surface processing, preventing it from adhering to the shaft surface and affecting the processing quality.

[0041] The surface cleaning mechanism 9 can be a rinsing cleaning mechanism. In this embodiment of the invention, for example... Figure 9As shown, the surface cleaning mechanism 9 includes a cleaning motor 92, a cleaning brush 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 along a horizontal direction perpendicular to the trapezoidal linear guide 2. The cleaning brush 93 is rotatably mounted on the mounting plate 91. The cleaning motor 92 is mounted on the mounting plate 91 and is driven by the cleaning brush 93. The sliding drive mechanism 94 is connected to the mounting plate 91 to drive the mounting plate 91 to slide along a horizontal direction perpendicular to the trapezoidal linear guide 2 against the frame 1.

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

[0043] In this invention, the sliding drive mechanism 94 and the linear drive mechanism 7 are generally pneumatic or hydraulic cylinders. The rotary drive device 5 is usually an electric motor.
