Description

Technical Field

[0001] This invention relates to the field of bearing processing equipment technology, specifically to a bearing processing positioning device and its positioning method. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. The strength and precision of the bearings directly affect the accuracy and quality of the equipment.

[0003] Publication No. CN 117226143 B discloses a bearing housing machining positioning device and method. Through a connecting block and transmission rod, and utilizing a limiting rod and a limiting through groove in sliding engagement, two positioning clamps can be driven to position and clamp the bearing housing body. Simultaneously, a first cylinder pushes the connecting block, causing the push plate to contact the bearing housing body. Combined with a fixed baffle, this ensures more stable positioning of the bearing housing body. Power transmission satisfies the positioning of the bearing housing body around its perimeter. Because a single first cylinder drives the device, the structure is more compact, contributing to weight reduction and cost reduction. The positioning frame's convex shaft slides into the limiting hole a, causing the positioning frame to deflect around the pin of the support sleeve. The downward adjustment of the positioning frame end, along with the engagement of the limiting rod... The elasticity of the compression spring b controls the downward pressure of the positioning ring on the bearing housing body, effectively reducing vibration during drilling and ensuring production stability. When the control lever slides the toothed plate downwards, the toothed plate drives the spur gear to rotate in the opposite direction. Since the locking block is rotatably connected to the rotating frame via a pin, and a compression spring c is provided between the locking block and the stop block, the rebound of the locking block can release the engagement of the ratchet sleeve groove, thus preventing the connecting rod and rotating shaft from rotating in the opposite direction. This effectively prevents the rotating disk from rotating, improving the stability of the bearing housing body's rotation adjustment and ensuring product processing quality. However, the above patent still has the following problems in actual use:

[0004] Although the bearing housing machining and positioning device and method can utilize the connecting block and transmission rod for transmission, and the limiting rod and limiting through groove for sliding engagement, which can drive two positioning clamps to position and clamp the bearing housing body, and the first cylinder pushes the connecting block to make the push plate contact the bearing housing body, and the fixed baffle can make the positioning of the bearing housing body more stable, it can only clamp and fix the bearing from the outside. When encountering tapered bearings, it is necessary to machine the outer side of the tapered bearing. Clamping and fixing the outer wall of the tapered bearing will affect the machining of the outer wall of the tapered bearing, thus limiting the use of the bearing housing machining and positioning device and making it unsuitable for bearings of different models and specifications.

[0005] A bearing machining positioning device and its positioning method are proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a bearing machining positioning device and method to solve the problem that, although the bearing housing machining positioning device and method mentioned in the background art can use the connecting block and transmission rod for transmission, and the limiting rod and the limiting through groove for sliding cooperation, it can drive two positioning clamps to position and clamp the bearing housing body. At the same time, the first cylinder pushes the connecting block, which can make the push plate contact the bearing housing body. With the cooperation of the fixed baffle, the positioning of the bearing housing body can be more stable. However, it can only clamp and fix the bearing from the outside. When encountering tapered bearings, it is necessary to process the outside of the tapered bearing. Clamping and fixing the outer wall of the tapered bearing will affect the processing of the outer wall of the tapered bearing. Therefore, the bearing housing machining positioning device is limited in use and cannot adapt to different models and specifications of bearings.

[0024] By adopting the above technical solution, the top positioning cone block can be raised and lowered by connecting the bracket and connecting the sliding rod, thereby enabling height adjustment of small bearing processing and facilitating clamping and fixing of large gears.

[0025] Preferably, support legs are fixedly installed around the bottom of the support base, and a second support rod is fixedly installed around the top of the support base. A positioning worktable is fixedly connected to the top of the second support rod, and a positioning groove is formed around the inside of the positioning worktable.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: This bearing processing positioning device and method, through a second rotating support driving the clamping rotating arm to rotate, utilizes the characteristic of the support locking block engaging with the support locking block to support the clamping rotating arm. The rotation of the first positioning clamping arm and the clamping rotating arm clamps and fixes the outer side of the small bearing. A lifting motor drives the lifting threaded rod to rotate, causing the lifting threaded bracket to move the lifting sliding rod and the lifting support plate up and down. This allows for the positioning and fixing sleeve and the top of the second positioning bracket to be positioned, facilitating the processing of large gears of different thicknesses. The specific details are as follows:

[0030] 1. By setting up a small bearing positioning mechanism, not only can the first connecting shaft and the first positioning threaded rod rotate through the rotating fixed bracket, causing the first positioning threaded sleeve to move up and down on the outside of the first positioning threaded rod, thereby driving the first positioning rotating rod to rotate, and under the action of the first rotating support, the first positioning clamping arm rotates, and through the second rotating support, the clamping rotating arm rotates. Utilizing the characteristic of the support locking block engaging with the support locking block, the rotating support rod supports the clamping rotating arm. Through the rotation of the first positioning clamping arm and the clamping rotating arm, the outer side of the small bearing is clamped and fixed. At the same time, by rotating the opening and closing knob, the bevel gear transmission assembly and the opening and closing threaded rod rotate, causing the opening and closing threaded sleeve to move... The sliding blocks slide relative to each other, and the protective pads support the inside of the small bearing, thereby improving the stability of the small bearing processing. When the outer side of the small bearing needs to be processed, the inner wall of the small bearing needs to be fixed. The small bearing is passed through the first positioning bracket and sleeved on the positioning cone block. By rotating the fixed bracket, the first connecting shaft, the first positioning threaded rod and the first positioning threaded rod are rotated, which causes the second positioning threaded sleeve and the first positioning threaded sleeve to move up and down, while driving the first positioning clamping arm and the second positioning clamping arm to rotate. The small bearing sleeved on the top of the reinforcing plate is pushed upward and placed against the bottom of the first positioning clamping arm, thereby fixing the small bearing and facilitating the processing of the outer side of the small bearing.

[0031] 2. By setting up a large bearing positioning mechanism, not only can the clamping motor drive the main clamping gear to rotate, but also the meshing connection between the main clamping gear and the driven clamping gear can cause the driven clamping gear to drive the second connecting shaft and the third positioning threaded rod to rotate. This causes the third positioning threaded sleeve to move up and down on the third positioning threaded rod, while simultaneously adjusting the rotation of the third positioning rotating rod, thereby unfolding the clamping plate. This not only clamps and fixes the exterior of the large gear, but also supports and fixes the inner wall of the large gear, facilitating the processing of the inner and outer walls of the large gear. The lifting motor drives the lifting threaded rod to rotate, causing the lifting threaded bracket to move up and down along the lifting sliding rod and the lifting support plate, which can position the positioning fixing sleeve and the top of the second positioning bracket, facilitating the processing of large gears of different thicknesses.

This allows the top of the positioning fixing sleeve 201 and the second positioning bracket 202 to be positioned, facilitating the processing of large gears of different thicknesses.

[0050] Working principle: Before using this bearing machining positioning device and its positioning method, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, rotating the fixed bracket 116 drives the first connecting shaft 103 and the first positioning threaded rod 104 to rotate, causing the first positioning threaded sleeve 105 to move up and down on the outside of the first positioning threaded rod 104, thereby driving the first positioning rotating rod 106 to rotate. Under the action of the first rotating support 107, the first positioning clamping arm 108 rotates, and the clamping rotating arm 112 rotates through the second rotating support 111. Utilizing the characteristic of the support locking block 115 engaging with the support locking block 110, the rotating support rod 114 supports the clamping rotating arm 112. The rotation of the first positioning clamping arm 108 and the clamping rotating arm 112 clamps and fixes the outer side of the small bearing. At the same time, rotating the opening and closing knob 118 drives the bevel gear transmission assembly 119 and the opening and closing threaded rod 120 to rotate, causing the opening and closing threaded sleeve 121 to drive the opening and closing slider 122 to slide relative to each other. The protective pad 123 supports the inside of the small bearing, thereby improving the stability of the small bearing processing and enabling the processing of the inner wall of the small bearing.

[0051] Secondly, when it is necessary to process the outer side of the small bearing, the inner wall of the small bearing needs to be fixed. The small bearing is passed through the first positioning bracket 101 and sleeved on the positioning cone block 124. By rotating the fixed bracket 116, the first connecting shaft 103, the first positioning threaded rod 104 and the first positioning threaded rod 105 are driven to rotate, so that the second positioning threaded sleeve 126 and the first positioning threaded sleeve 105 move up and down, while driving the first positioning clamping arm 108 and the second positioning clamping arm 129 to rotate. The small bearing sleeved on the top of the reinforcing plate 131 is pushed upward and placed against the bottom of the first positioning clamping arm 108, thereby fixing the small bearing and facilitating the processing of the outer side of the small bearing.

[0052] Finally, the clamping motor 203 drives the clamping main gear 204 to rotate. Utilizing the meshing connection between the clamping main gear 204 and the clamping driven gear 205, the clamping driven gear 205 drives the second connecting shaft 206 and the third positioning threaded rod 207 to rotate. This causes the third positioning threaded sleeve 208 to move up and down on the third positioning threaded rod 207, while simultaneously rotating the third positioning rotating rod 209. This unfolds the clamping plate 210, enabling not only external clamping and fixing of the large gear but also support and fixing of its inner wall, facilitating the processing of both the inner and outer walls of the large gear. The lifting motor 222 drives the lifting threaded rod 223 to rotate, causing the lifting threaded bracket 224 to move up and down, along with the lifting sliding rod 225 and the lifting support plate 226. This allows the top of the positioning fixing sleeve 201 and the second positioning bracket 202 to be positioned, facilitating the processing of large gears of different thicknesses.

10. A method for manufacturing a dry-type capacitor bushing insulation structure, using a bearing processing positioning device as described in claim 9, wherein the positioning method steps are as follows: Step 1: By rotating the fixed bracket (116), the first connecting shaft (103) and the first positioning threaded rod (104) are driven to rotate, causing the first positioning threaded sleeve (105) to move up and down on the outside of the first positioning threaded rod (104), thereby driving the first positioning rotating rod (106) to rotate. Under the action of the first rotating support (107), the first positioning clamping arm (108) is rotated. The clamping rotating arm (112) is driven to rotate through the second rotating support (111). Taking advantage of the engaging connection between the support locking block (115) and the support locking block (110), The rotating support rod (114) supports the clamping rotating arm (112). The first positioning clamping arm (108) and the clamping rotating arm (112) rotate to clamp and fix the outer side of the small bearing. At the same time, the opening and closing knob (118) drives the bevel gear transmission assembly (119) and the opening and closing threaded rod (120) to rotate, so that the opening and closing threaded sleeve (121) drives the opening and closing slider (122) to slide relative to each other. The protective pad (123) supports the inside of the small bearing, thereby improving the stability of the small bearing processing and enabling the inner wall of the small bearing to be processed. Step 2: When it is necessary to process the outer side of the small bearing, the inner wall of the small bearing needs to be fixed. The small bearing is passed through the first positioning bracket (101) and sleeved on the positioning cone block (124). By rotating the fixed bracket (116), the first connecting shaft (103), the first positioning threaded rod (104) and the first positioning threaded rod (104) are driven to rotate. This causes the second positioning threaded sleeve (126) and the first positioning threaded sleeve (105) to move up and down, while driving the first positioning clamping arm (108) and the second positioning clamping arm (129) to rotate. The small bearing sleeved on the top of the reinforcing plate (131) is pushed upward and placed against the bottom of the first positioning clamping arm (108), thereby fixing the small bearing and facilitating the processing of the outer side of the small bearing. Step 3: Using the clamping motor (203) to drive the clamping main gear (204) to rotate, and taking advantage of the meshing connection between the clamping main gear (204) and the clamping driven gear (205), the clamping driven gear (205) drives the second connecting shaft (206) and the third positioning threaded rod (207) to rotate. This causes the third positioning threaded sleeve (208) to move up and down on the third positioning threaded rod (207) while simultaneously rotating the third positioning rotating rod (209), thereby unfolding the clamping plate (210). This not only clamps and fixes the outside of the large gear, but also supports and fixes the inner wall of the large gear, facilitating the processing of the inner and outer walls of the large gear. By driving the lifting threaded rod (223) to rotate through the lifting motor (222), the lifting threaded bracket (224) drives the lifting sliding rod (225) and the lifting support plate (226) to move up and down, which can place the positioning fixing sleeve (201) and the top of the second positioning bracket (202), facilitating the processing of large gears of different thicknesses.
