Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0014] This eccentric fixture is divided into thirteen parts, such as figure 2 As shown, it includes screw 1, adjusting nut 2, screw rod 3, handle 4, sleeve 5, bearing cover 6, spacer 7, thrust ball bearing 8, bearing seat 9, bolt 10, reamer 11, adjustment piece 12, Screw 13.

[0015] First screw rod 13 front end external thread and internal thread on the workpiece are connected in place, then reamer 11, adjusting piece 12 is contained on the screw rod 13, reamer 11 and adjusting piece 12, adjusting piece 12 and screw rod 13 adopt shaft hole to cooperate. Then bearing seat 9, thrust ball bearing 8, spacer 7, and bearing cover 6 are mounted on the screw rod 13 in sequence, and are matched with the shaft hole of the screw rod 13, and are screwed and fixed by the adjusting nut 2 and the screw rod 13, the handle 4, the bolt 10 and the sleeve The barrel 5 is th...

Abstract

The invention discloses a reamer device for reaming sealing holes and bottom surfaces of inner sides of combustion chamber shells. The reamer device is characterized in that a screw 13 is directly connected with a workpiece in a threaded manner, a reamer 11 and an adjusting plate 12 are mounted on the screw 13, and the screw 13 has positioning and guiding functions. A bearing block 9, a thrust ball bearing 8, a cushion block 7 and a bearing cover 6 are sequentially mounted on the screw 13, an adjusting nut 2 is fixedly connected with the screw 13 in a threaded manner, and the feed rate of the reamer 11 can be controlled by means of rotating a rotary rod 3 on the adjusting nut 2. A handle 4 and a bolt 10 are connected with a sleeve 5 in a threaded manner, the bolt 10 simultaneously locks the reamer 11, the reamer 11 is driven to ream the workpiece by means of turning the handle 4, and a machining function is realized. The diameter and the height of a sealing hole are limited by the reamer 11, and the depth of the sealing hole is controlled by the adjusting plate 12. The reamer device has the advantages of simplicity in operation, high practicality, low labor intensity, high production efficiency, reliability in reaming quality and the like.

Description

technical field [0001] The invention relates to a reamer device, in particular to a reamer device for reaming a sealing hole and a bottom surface of an ignition seat at the inner bottom of a combustion chamber shell. Background technique [0002] At present, the reaming process at home and abroad is common to process the holes on the surface of the workpiece, and mechanical reaming or manual reaming is mostly used, which is simple to operate and easy to implement. For the sealing hole and the bottom surface of the ignition seat at the inner bottom of the combustion chamber shell, due to the limited working stroke of the machine tool, it is difficult to observe and operate, and it is impossible to perform mechanical reaming. Manual ordinary reaming is not easy to ensure the processing quality. There is no good processing at home and abroad. method. Developed this set of reamer device for reaming the sealing hole and bottom surface of the bottom ignition seat inside the combu...
