Abstract
A clamp for secondary processing of a knife handle comprises a clamping sleeve and a pull rod. The clamping sleeve is internally provided with a cutter handle hole and a pull rod hole which are axially communicated. The tool handle hole is provided with a conical surface with a big front part and a small back part. The pull rod hole is internally threaded with a pull rod. An annular boss is arranged at the joint of the cutter handle hole and the pull rod hole. The boss is provided with an anti-rotation screw. The clamp can save time for replacing the clamp, is convenient for workers to replace, has small structure, light weight and saves working time, and is suitable for being used when HSK knife handle clamps for processing single or multiple products are processed.
Description
Technical Field
The utility model belongs to the machining field, in particular to anchor clamps are used in handle of a knife secondary operation.
Background
When this kind of HSK standard finished product handle of a knife in the past secondary operation, because the stalk portion can not harm for the finished product of processing, can use the special supporting anchor clamps of processing (dividing head), change at every turn and need adjust the position precision, anchor clamps are very heavy (50 kg), need two at least workman's hands and masters to move together, and the clamping detects the waste time, is not suitable for one or several product processing.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a handle of a knife is anchor clamps for secondary operation solves the very heavy problem of conventional anchor clamps weight, convenient change.
The technical scheme is as follows:
a clamp for secondary processing of a knife handle comprises a clamping sleeve and a pull rod.
The technical key points are as follows:
the clamping sleeve is internally provided with a cutter handle hole and a pull rod hole which are axially communicated.
The tool handle hole is provided with a conical surface with a big front part and a small back part.
The pull rod hole is internally threaded with a pull rod.
An annular boss is arranged at the joint of the cutter handle hole and the pull rod hole.
The boss is provided with an anti-rotation screw.
The advantages are that:
the clamp can save time for replacing the clamp, is convenient for workers to replace, has a small structure, light weight (2.5 kg, and can be operated alone), saves working time, and is suitable for being used in the process of processing HSK knife handle clamps of single or multiple products.
Drawings
Fig. 1 is the utility model (clamping sleeve and pull rod), the decomposition structure schematic diagram of the standard HSK handle of a knife of waiting secondary operation.
Fig. 2 is the utility model discloses, treat the assembly structure sketch map of secondary operation's standard HSK handle of a knife and three-jaw (holding) chuck.
The tool comprises a standard HSK tool shank 1, a clamping sleeve 2, a pull rod 3, an anti-rotation screw 4, a tool shank hole 5, a pull rod hole 6, a conical surface 7, a primary processing surface 8, a boss 9, a three-jaw chuck 10 and a secondary processing area 11.
Detailed Description
A clamp for secondary processing of a knife handle comprises a clamping sleeve 2 and a pull rod 3.
A cutter handle hole 5 and a pull rod hole 6 which are axially communicated are arranged in the clamping sleeve 2.
The tool shank hole 5 is provided with a conical surface 7 with a large front part and a small back part, and the conical surface 7 is matched with a primary processing surface 8 (a product is used here and cannot be damaged in secondary processing) which is already processed on the standard HSK tool shank 1.
The pull rod 3 is connected with the inner thread of the pull rod hole 6, and the front end of the pull rod 3 is connected and tensioned with the rear end hole of the standard HSK knife handle 1 through the thread.
Furthermore, an annular boss 9 is arranged at the joint of the handle hole 5 and the pull rod hole 6.
The boss 9 is provided with an anti-rotation screw 4 for preventing the standard HSK knife handle 1 from rotating in the clamping sleeve 2.
The front end column head of the anti-rotation screw 4 is clamped in the key groove at the rear end of the standard HSK knife handle 1.
The anti-rotation screw 4 is in threaded connection with the boss 9.
Therefore, the outer wall of the pull rod hole 6 is a straight shank, so that the clamp (the three-jaw chuck 10) of a straight shank tool can be used for secondary processing on the secondary processing area 11, and the processed HSK shank part (the primary processing surface 8) of the finished product cannot be damaged.
The machined primary machining surface 8 on the standard HSK cutter handle 1 is in taper fit with the conical surface 7.
The key groove at the rear end of the standard HSK knife handle 1 is matched and clamped with the anti-rotation screw 4.
The pull rod 3 is screwed into the pull rod hole 6, and then the front end of the pull rod 3 is screwed into the screw threads of the cutter handle hole 5 and the rear end hole of the standard HSK cutter handle 1.
