Technical Field

The invention belongs to the technical field of heat treatment tools, and particularly relates to a heat treatment tool in a camshaft process for a cam rotor pump.

Background

The cam rotor pump is internally provided with a cam rotating rod, the shape of the rotating rod looks like a multi-segment crankshaft structure, namely the shape of the rotating rod structure is irregular, and the rotating rod structure needs to be subjected to a heat treatment process in the manufacturing process so as to improve the strength and the deformation resistance of the rotating rod structure.

Based on the above, the designer discovers that the camshaft in the cam rotor pump with the crankshaft structure can directly fall into the furnace chamber when the camshaft is directly placed in the heat treatment furnace without using a tooling mechanism in the process of the heat treatment annealing process, so that the local heat is not thorough, the internal structure of the camshaft cannot be sufficiently changed, the retraction time of the camshaft cannot be prolonged, and the working efficiency is influenced.

Therefore, in view of the above, research and improvement are made in view of the existing structure and defects, and a heat treatment tool in the camshaft process for the cam rotor pump is provided, so as to achieve the purpose of higher practical value.

Disclosure of Invention

In order to solve the technical problems, the invention provides a heat treatment tool in a camshaft process for a cam rotor pump, which aims to solve the problems that in the heat treatment annealing process of a camshaft in the cam rotor pump with the existing crankshaft structure, when the camshaft is directly placed in a heat treatment furnace without using a tool mechanism, the camshaft directly falls in a furnace chamber, so that the local heat is incomplete, the internal structure of the camshaft cannot be fully changed, the withdrawal time of the camshaft cannot be prolonged, and the working efficiency is influenced.

The invention relates to a purpose and an effect of a heat treatment tool in a camshaft process for a cam rotor pump, which are achieved by the following specific technical means:

a heat treatment tool in the camshaft process for a cam rotor pump comprises a lower seat and an upper seat; the lower seat is a circular cavity seat, dense and numb waist-shaped air holes are formed in the bottom surface of the lower seat, and a lower welding pipe is welded in the middle of the inner cavity of the lower seat in a vertical mode; the upper seat is of a circular cavity structure, a circle of hook rotating pipes are uniformly welded on the bottom surface of the upper seat, and a hook is rotatably matched in each hook rotating pipe; an upper welded pipe is welded in the middle of the bottom surface of the upper seat, and a rotating rod is further matched with the upper welded pipe in a downward rotating mode; an extension rod is welded at the middle position of the outer wall of the rotating rod outwards, and an inserting sleeve is welded at the outer end of the extension rod.

Further: the circumference outer wall of lower seat equipartition is seted up the equipartition groove of round rectangle notch structure, and all still welds on these equipartition grooves and take a seat, and these take a seat and become the one-to-one position correspondence with the couple mutually.

Further: the size of lower seat is less than the size of upper seat, and is a vertical mode screw-thread fit and has a threaded rod in welding pipe down, and the top of threaded rod and the bottom segment screw hole screw-thread fit of bull stick.

Further: the peripheral wall of the lower seat is welded with a circle of baffle plates, the baffle plates are welded on the peripheral wall of the lower seat in an inclined mode, and an inward-sinking type baffle cavity is further arranged on one side face of each baffle plate.

Further: the bottom surface intermediate position of lower seat is installed in the base through the mode of welded roating seat cooperation rotation axis, and this base is circular cavity structure, and its cavity is down to the equipartition installs four truckles in its inner chamber.

Further: the plug cavity of the plug bush is of an inner hexagonal cavity structure.

Further: and a bearing is embedded in each pipe cavity of the hook rotating pipe, and the top end of the hook is inserted and embedded in the rotating bearing.

Further: a bearing is also embedded in the tube cavity of the upper welding tube, and the top end of the rotating rod is inserted and embedded through the bearing.

Compared with the prior art, the invention has the following beneficial effects:

the tool is designed with an upper part and a lower part which can rotate, when the tool is used for hanging a gear physical shaft of a crank and is put into a heat treatment furnace for annealing treatment, the tool can rotate through the mode that an external rod piece is inserted into an inserting cavity, so that the crankshaft workpiece hung on the tool can be better subjected to heat effect treatment, when the workpiece shaft is hung, if the length is too long, the workpiece shaft can be supported at the bottom through a seat on a bottom seat to form inclined placement, if the size of the workpiece shaft is shorter, the workpiece shaft can be directly hung without bottom support, when the top seat mechanism can be jacked by the external rod piece, the rotating action is realized, the short shaft piece is more conveniently placed, the long shaft piece can be supported at the bottom except for the top suspension, and the upper part and the lower part are connected together through a screw rod, so that the upper part and the lower part can be used for adjusting the distance, the length of the hung workpiece is required to be adjusted in advance, so that the tool mechanism is flexible and has better practicability.
