Summary of the invention
When solving in the prior art thermal treatment; Adopt the thermal treatment casher box to stack workpiece in a jumble, workpiece heats, quenches inhomogeneous, causes hardness bad; Workpiece is fitted together the problem of damaging easily dispersedly simultaneously; The invention provides a kind of heat treatment clamping jig, can with workpiece neat arrange placement, be beneficial to heat treatment furnace and carry out thermal treatment preferably.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of heat treatment clamping jig; Comprise two blocks of clamping workpiece plates, some support bars is characterized in that: be connected through support bar at two clamping workpiece plates; On nethermost clamping workpiece plate, be provided with some first clamping workpiece holes; The external diameter in the said first clamping workpiece hole also is provided with some second clamping workpiece holes less than the external diameter of workpiece on intermediate piece clamping plate, the external diameter in the said second clamping workpiece hole is greater than the external diameter of workpiece.
Aforesaid a kind of heat treatment clamping jig is characterized in that: also include uppermost clamping workpiece plate.
Aforesaid a kind of heat treatment clamping jig is characterized in that: said support bar comprises four double end support bars and four single head support bars, and said single head support bar bottom is provided with internal thread hole, and the top is provided with outside screw, and the shaft external diameter is bigger than outside screw; Said double end support bar two ends all are provided with outside screw, and the shaft external diameter is bigger than outside screw.
Aforesaid a kind of heat treatment clamping jig; It is characterized in that: on four angles of three clamping workpiece plates, offer four bolts hole respectively; The outside screw of said four double end support bar bottoms passes four bolts hole of bottom clamping workpiece plate respectively and locks with the joint nut; The outside screw of said four double end supporting bar tops passes the bolt hole of intermediate piece clamping plate respectively; And be connected with the internal thread hole of corresponding single head support bar one end, the outside screw of said four single head support bar the other ends passes four bolts hole of uppermost clamping workpiece plate respectively.
Aforesaid a kind of heat treatment clamping jig is characterized in that: the shaft external diameter of said support bar is greater than the aperture in clamping workpiece crab bolt hole.
Aforesaid a kind of heat treatment clamping jig is characterized in that: can place the length different workpiece in the clamping workpiece hole of said clamping workpiece plate.
Aforesaid a kind of heat treatment clamping jig is characterized in that: said heat treatment clamping jig can be provided with polylith clamping workpiece plate.
The invention has the beneficial effects as follows: heat treatment clamping jig of the present invention can insert workpiece in the clamping workpiece hole of clamping workpiece plate; And workpiece is fixed through three blocks of clamping workpiece plates; Put into thermal treatment with casher box heat treatment clamping jig is whole again, send into heat treatment furnace at last and heat-treat, workpiece is heated, quenches more even when heating like this; The quality product of producing is better; The neat discharging of workpiece rule simultaneously, also avoided put into, taking-up, handling process cause damages, cause the damage of workpiece and scrap.
Description of drawings
