But the painting mold fixture of facilitating centering
The present invention relates to a kind of anchor clamps that are used for clamping japanning mould core, but a kind of painting mold fixture of facilitating centering specifically.
At present, the japanning mould has been widely used in the manufacture process that the enamel-covered wire enamelled coating applies, and is less because of japanning mould core excircle dimension, when the processing endoporus, is difficult for processed equipment clamping.Common way is to adopt to process the major diameter core rod to make things convenient for the process equipment clamping, treat to re-use after endoporus machines equipment such as lathe with external cutting to the diameter that needs.This processing method is unfavorable for large batch of production and processing, has increased the production cost of enterprise simultaneously.
Summary of the invention
The objective of the invention is to be directed against the weak point that exists in the prior art, but a kind of painting mold fixture of facilitating centering is provided, carry out endoporus processing, improve the production efficiency of japanning mould to make things convenient for core rod.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: it is made up of the upper and lower anchor clamps through thread connection; The through hole that is used to process that last anchor clamps below and lower clamp top have mold cavity and communicate with mold cavity; Mold cavity diameter on the last anchor clamps cooperates with the japanning mould core; The mold cavity degree of depth on the last anchor clamps is less than the height of japanning mould core, and the mold cavity on the lower clamp is the up big and down small conical cavity of opening, mold cavity upper and lower opening place diameter respectively greater than, less than japanning mould core diameter.During use, core rod to be processed is put into the mold cavity of anchor clamps, lower clamp is connected with last anchor clamps through threaded engagement again, owing to the mold cavity of lower clamp is tapered, core rod to be processed can be regulated the center automatically.
For simplified structure, make things convenient for anchor clamps processing, there is the connection holes that cooperates with last anchor clamps outer wall the mold cavity upper end of lower clamp, and the connection holes inwall is provided with internal thread, and last anchor clamps are provided with the external screw thread of the screw-internal thread fit on the connection holes inwall with lower clamp.Last anchor clamps lower end screws in the lower clamp, and the volume of anchor clamps is little, is prone to processing.
Open for ease, the below of last anchor clamps top and lower clamp has the open hole of symmetry.Can assemble easily and open with the special opening instrument.
Can be known that by technique scheme the present invention adopts upper and lower clamp mode with core rod clamping to be processed, core rod can be regulated the center automatically in the anchor clamps clamping process, and gripping and opening are all convenient, and simple in structure, are prone to processing.

The specific embodiment
As depicted in figs. 1 and 2; Last anchor clamps 1 below has mold cavity 11; Mold cavity 11 diameters cooperate with japanning mould core 3; Mold cavity 11 degree of depth are less than the height of japanning mould core 3, and the top has through hole that is used to process 13 that communicates with mold cavity 11 and the symmetrically arranged open hole 12 that is used for opening, and last anchor clamps 1 outer wall below is provided with external screw thread.
Like Fig. 3 and shown in Figure 4; Lower clamp 2 tops have the connection holes 22 that cooperates with last anchor clamps 1 outer wall below; The connection holes inwall is provided with the internal thread that cooperates with the external screw thread of last anchor clamps 1 outer wall below; Connection holes 22 belows are provided with taper die chamber 23, mold cavity 23 upper and lower opening place diameters respectively greater than, less than japanning mould core 3 diameters, lower clamp 2 belows have through hole that is used to process 24 that communicates with mold cavity 23 and the symmetrically arranged open hole 21 that is used for opening.
As shown in Figure 5; When upper and lower anchor clamps 1,2 pass through thread connection; Japanning mould core 3 bottoms that are positioned at the mold cavity 11 of anchor clamps 1 contact with the taper seat in the taper die chamber 23 of lower clamp 2; Make japanning mould core 3 be in the symmetrical centre position of lower clamp all the time, thereby can regulate the center automatically.
Special spanner structure such as Fig. 6 and shown in Figure 7; Form by handle 4 and spanner 5; Have on the spanner 5 with last anchor clamps 1, lower clamp 2 on the corresponding convexity 6 of open hole 12,21; Use two spanners to insert in the open hole 12,21 of upper and lower anchor clamps protruding 6 respectively, promptly rotatable handgrip carries out breakdown action.
