[0039] The following further describes the present utility model with specific embodiments. Refer to Figure 1 —6:

[0040] A honing and lapping processing device for a bushing, comprising a frame 1. A feeding station, a discharging station, a plurality of honing and lapping stations, and a feeding device for moving the bushing from the previous station to the next station are provided on the frame 1. Each honing and lapping station is provided with a fixture assembly for fixing the bushing and a honing and lapping device located above the fixture assembly. The feeding device comprises a strip-shaped plate 3 driven by a power device 2 to complete a reciprocating motion of rising - translating - descending. A plurality of fixture assemblies are arranged on a straight line parallel to the length direction of the strip-shaped plate 3 and are located between the feeding station and the discharging station. A plurality of clamping devices for clamping the bushing are arranged at intervals along the length direction of the strip-shaped plate 3. In this embodiment, three honing and lapping stations are provided.

[0041] The working principle of the present utility model: As Figure 1 shown, the power device 2 drives the strip-shaped plate 3 to achieve a reciprocating motion of rising - translating - descending, thereby driving each fixture assembly to achieve a reciprocating motion of rising - translating - descending. The clamping devices arranged on the strip-shaped plate 3 clamp the bushing and then drive their respective bushings to rise, translate, and descend, that is, drive the bushing to move from the previous station to the next station. After the fixture assembly clamps the bushing, the clamping device releases the bushing, and the clamping device rises - translates in the opposite direction to a position between the two stations to avoid interference during the processing by the honing and lapping device. Each honing and lapping device performs honing and lapping processing on the corresponding bushing. After the processing is completed, the clamping device continues to translate in the opposite direction, move down to clamp the bushing, and then drive their respective bushings to rise, translate, and descend, and so on. The clamping device located at the end and close to the feeding station clamps the bushing at the feeding station and moves it to the first honing and lapping station. The middle clamping device clamps the bushing at the previous honing and lapping station and moves it to the next honing and lapping station. The clamping device located at the end and close to the discharging station clamps the bushing at the last honing and lapping station and moves it to the discharging station.

[0042] The present utility model sets a plurality of honing and lapping stations in one device. The feeding device moves the bushing from the previous station to the next station. All honing and lapping processing of the bushing can be completed through the device of the present utility model. The bushing does not need to be transferred, there are few semi-finished products in the workshop, the occupied space and capital cost are low, and the production efficiency is high. At the same time, the transfer of the bushing between each process can be completed by one feeding device. The structure is simple, easy to install, and only one power device 2 is required, with few components, effectively reducing the cost.

[0043] In this embodiment, the power device 2 is a high-speed picking and placing device driven by a rotary mechanism unit disclosed in Chinese Utility Model (Publication No. CN203993885U, Application Date: July 8, 2014, Publication Date: December 10, 2014), and the strip-shaped plate 3 is installed on its longitudinal linear guide rail.

[0044] Feeding mechanism at the feeding station: At the feeding station, there is a turntable 4 driven by a first driving device. A plurality of placing blocks 5 for placing bushings are evenly distributed in a circumferential manner on the turntable 4. A placing hole 6 adapted to the outer side wall of the bushing is provided on the placing block 5. During the machining process of the honing device, bushings can be placed in the placing holes 6 at one time. After the bushing in the same straight line as the honing station is taken away, the first driving device drives the turntable 4 to rotate, rotating the adjacent bushing to the same straight line as the honing station for the next clamping. The present utility model sets the turntable 4 to place bushings, enabling multiple bushings to be fed at one time without waiting for feeding, reducing the labor intensity of the operator; the present utility model sets the placing block 5 to place bushings, and for machining bushings of different models, only the corresponding bushing needs to be replaced, with high adaptability.
