Description

Technical Field

[0001] The utility model relates to a processing jig, in particular to a bushing edge cutting processing jig. Background Art

[0002] The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing and wear protection. It refers to a ring sleeve that acts as a gasket. During the bushing processing and production process, the bushing needs to be chamfered, and a bushing chamfering jig is needed.

[0003] For example, a bushing trimming tool disclosed in Chinese patent publication number CN213889087U includes an operating table, a mounting and positioning assembly is rotatably connected to the middle position of the top of the operating table, the mounting and positioning assembly includes a mounting rod, the diameter of the mounting rod is matched to the inner diameter of the bushing, the mounting rod is rotatably connected to the operating table through a bearing, the mounting and positioning assembly also includes a drive motor system, the drive motor system is fixedly connected to the bottom end of the operating table, the bottom end of the mounting rod passes through the operating table and is connected to the output end of the drive motor system, and a cutting groove is provided on the outer side of the middle part of the mounting rod. By providing a clamping assembly and a mounting and positioning assembly that are symmetrical up and down, compared with traditional clamps such as vises, the fixing structure is more reasonable, avoiding the situation where the outer side of the bushing is easy to slide when fixed, which is beneficial to improving the bushing trimming effect and enhancing the practicality of the device.

[0004] Some problems are found in the use of the above-mentioned existing bushing edge trimming jig. First, the bushing is put on the installation and positioning component. The diameter of the installation and positioning component is fixed. The inner diameters of bushings of different specifications are not the same. Only bushings with one inner diameter can be fixed and processed, which has a low practicality. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By placing the bushing on the lower tray and putting it on the column, the contact roller will press against the inner wall of the bushing, thereby preventing the outer wall of the bushing from deforming inward due to force during the cutting operation.

[0014] 2. The internal threaded sleeve can be driven to move by rotating the threaded rod, the movement of the internal threaded sleeve can drive the bracket to move, the movement of the bracket can drive the contact roller to move, thereby adjusting the position of the contact roller so that the contact roller can contact the inner wall of the bushing with different inner diameters, and can adapt to the processing of bushings with different inner diameters.

[0022] In this embodiment, the bushing is placed on the lower tray 2 and sleeved on the column 3, with the resistance roller 401 facing the cutter. During the edge trimming operation, the resistance roller 401 will resist the inner wall of the bushing, thereby preventing the outer wall of the bushing from deforming inward due to force during the cutting operation. At the same time, the threaded rod 303 is threadedly matched with the internal threaded sleeve 402, and rotating the threaded rod 303 can drive the internal threaded sleeve 402 to move. The movement of the internal threaded sleeve 402 can drive the bracket 4 to move. The movement of the bracket 4 can drive the resistance roller 401 to move, thereby adjusting the position of the resistance roller 401 so that the resistance roller 401 can resist the inner wall of the bushing with different inner diameters, thereby processing bushings with different diameters.

[0023] Among them, in order to achieve the purpose of clamping the bushing, the present device adopts the following technical scheme: a hydraulic cylinder 101 is fixedly installed on the processing platform 1, a connecting frame 102 is fixedly installed on the upper end of the hydraulic cylinder 101, a rotating drum 103 is fixedly installed on the other end of the connecting frame 102, a pressure plate 104 is rotatably installed under the rotating drum 103, a driven gear plate 203 is fixedly installed under the connecting plate 202, a power motor 5 is fixedly installed under the processing platform 1, and a driving gear 501 is fixedly installed on the output end of the power motor 5, and the driving gear 501 cooperates with the connecting plate 202.

[0024] By starting the hydraulic cylinder 101, the connecting frame 102 can be driven to move, and the movement of the connecting frame 102 will drive the rotating drum 103 and the pressure plate 104 to move. The pressure plate 104 presses down on the upper end of the bushing, and cooperates with the lower tray 2 to clamp and fix the bushing. Starting the power motor 5 can drive the driving gear 501 to rotate. The driving gear 501 and the driven gear plate 203 cooperate with each other, so that the rotation of the driving gear 501 will drive the driven gear plate 203 to rotate, and the rotation of the driven gear plate 203 will drive the lower tray 2 to rotate, thereby driving the bushing to rotate.

[0025] Among them, in order to achieve the purpose of fixing the column 3, the present device adopts the following technical solutions: a fixing foot 301 is fixedly installed on the column 3 and close to the lower edge, a fixing bolt 302 is arranged in the fixing foot 301, a knob 304 is fixedly installed at one end of the threaded rod 303, and a telescopic connecting rod 403 is fixedly installed on one side of the bracket 4 and located above and below the internal threaded sleeve 402.

[0026] The threaded rod 303 can be driven to rotate by the knob 304. A threaded fixing hole is provided on the processing platform 1. The fixing bolt 302 is passed through the fixing foot 301 and screwed into the threaded fixing hole to fix the column 3 on the processing platform 1. The telescopic connecting rod 403 is used to limit the bracket 4 to only move horizontally.

[0027] The working principle and use process of the utility model: when using, the device needs to be placed in a suitable position. First, according to the inner diameter of the bushing, the threaded rod 303 needs to be rotated by the knob 304. The rotation of the threaded rod 303 will drive the bracket 4 to move, and the movement of the bracket 4 will drive the resistance roller 401 to move. After adjusting the resistance roller 401 to a suitable position, the bushing is placed on the lower tray 2 and sleeved on the column 3. The resistance roller 401 will resist the inner wall of the bushing. Start the hydraulic cylinder 101 to drive the pressure plate 104 to press the upper edge of the bushing, and the bushing can be fixed between the lower tray 2 and the pressure plate 104. Start the power motor 5 to drive the lower tray 2 to rotate. The rotation of the lower tray 2 will drive the bushing to rotate. At this time, the cutter can be controlled to perform the edge trimming operation.
