Abstract
The utility model relates to a fixture for turning the threads of a straight shank hanging hook, with convenient clamping. The fixture is provided with a base capable of being clamped by a chuck of a machine tool. A cushion plate for placing a hook body of a straight shank hanging hook and parallel to the central axis of the base extends out of the side surface of the base; the cushion plate is provided with a mandrel as well as a pressure plate and a screw nut which are matched with the mandrel, the upper part of the mandrel is provided with a screw rod, and the diameter of the mandrel is equal to the internal diameter of a central hook ring of the straight shank hanging hook; the cushion plate is further provided with at least two positioning pins; when the hook body of the straight shank hanging hook is arranged on the cushion plate, the mandrel is inserted into the central hook ring of the straight shank hanging hook; the positioning pins are contacted with the outer side of the hook body of the straight shank hanging hook; the end of the hook body of the straight shank hanging hook is contacted with the side surface of the base; and the pressure plate penetrates through the screw rod on the mandrel and is pressed on the hook body of the straight shank hanging hook by the screw nut. When in processing, the hook body of the straight shank hook is clamped on the fixture, and then the fixture is clamped on the chuck of the machine tool to perform the thread processing of the straight shank hanging hook.
Description
Technical field
The utility model belongs to the machine cut processing tool, specifically a kind of turning clamp of staight shank suspension hook screw thread.
Background technology
The staight shank suspension hook comprises coupler body part and the screw portion that is connected with the hoist cable joint.Because staight shank suspension hook coupler body is not a revolving body, can't use the scroll chuck of lathe during clamping.During at present with machined into staight shank suspension hook screw rod is that the hook body segment packing is clipped on the chuck of lathe, therefore clamping is relatively more difficult, be difficult for the pivot of centering screw portion to be processed, and the adjustment time of clamping is long, error is also bigger, and its production efficiency is very low.
Summary of the invention
Problem to be solved in the utility model is: the turning clamp that a kind of staight shank suspension hook screw thread of convenient mounting and clamping is provided.
The technical scheme that addresses the above problem is: the turning clamp of the staight shank suspension hook screw thread that is provided have one can be by the pedestal of machine chuck clamping, the backing plate of a placement staight shank suspension hook coupler body parallel with the pedestal central axis is extended in the side of this pedestal, the mandrel that it is screw rod that this backing plate is provided with a top, pressing plate that cooperates with mandrel and nut, axle diameter equals the center shackle internal diameter of staight shank suspension hook, also be provided with at least two alignment pins on this backing plate, when staight shank suspension hook coupler body is placed on the backing plate, mandrel is inserted in the center shackle of staight shank suspension hook, the outer side contacts of alignment pin and staight shank suspension hook coupler body, pressing plate are passed the screw rod on the mandrel and are pressed on the staight shank suspension hook coupler body by nut.Add man-hour, with the coupler body clamping of staight shank suspension hook on anchor clamps, again with these anchor clamps clamping on the chuck of lathe, can carry out screw thread processing to the staight shank suspension hook.
Above-mentioned pedestal is preferably cylinder, can frock be clamped on the scroll chuck of lathe easily like this.
Above-mentioned alignment pin can be two or more, and it is four for example when above that alignment pin is two, two positions that are distributed in the staight shank suspension hook coupler body outside near pedestal wherein, and two other is positioned at the staight shank portion both sides of staight shank suspension hook coupler body, can satisfy positioning requirements.Generally speaking, preferably two of alignment pins are when staight shank suspension hook coupler body is placed on the backing plate, two alignment pins are positioned at the staight shank portion both sides of staight shank suspension hook coupler body, the contacts side surfaces of staight shank suspension hook coupler body end and pedestal, like this, not only simple in structure, and good positioning effect.
Because the shape approximation of staight shank suspension hook coupler body is circular,, above-mentioned backing plate lacks the shape backing plate so being preferably circle.
The utility model utilizes pedestal side, mandrel and alignment pin that the staight shank suspension hook is positioned, fix staight shank suspension hook coupler body with nut and pressing plate, not only simple in structure, convenient mounting and clamping, and accurate positioning, the machining accuracy height, surface quality is good, also significantly reduce simultaneously the non-cutting time of processing, alleviated operator's labour intensity.
Description of drawings
Fig. 1 is the structure chart of the utility model most preferred embodiment.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structure chart of the utility model most preferred embodiment center platen.
Fig. 4 the has been the utility model clamping assembly figure of staight shank suspension hook.
The specific embodiment
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
As Fig. 1, Fig. 2 and shown in Figure 3: the pedestal 1 of anchor clamps is a cylinder, and backing plate 3 lacks the shape backing plate for circle, and it is welded on the pedestal 1, and parallel with the central axis 2 of pedestal 1, and promptly the pedestal side is vertical with plane on the backing plate.Backing plate 3 is provided with mandrel 4 and two alignment pins 6 of a band screw rod 5, and mandrel 4 is used for the location of staight shank suspension hook center shackle, and two alignment pins 6 are used for the location of the staight shank portion of staight shank suspension hook, and pedestal 1 side is used for the location of staight shank suspension hook coupler body; Promptly, when the coupler body of staight shank suspension hook 10 was placed on the backing plate 3, mandrel 4 was inserted in the center shackle of staight shank suspension hook 10, two alignment pins 6 respectively with the staight shank portion contact both sides of staight shank suspension hook 10, the contacts side surfaces of staight shank suspension hook coupler body end and pedestal 1 has realized the location to staight shank suspension hook 10.The centre bore of pressing plate 7 passes the screw rod 5 on the mandrel 4, is pressed on the staight shank suspension hook coupler body, again nut 8 is screwed on the mandrel screw rod 5, and clamping platen 7, thus staight shank suspension hook 10 is fixed on the anchor clamps.Add man-hour, anchor clamps are clamped on the scroll chuck of lathe, can implement screw thread processing the part to be processed 11 of staight shank suspension hook.
Referring to Fig. 4, above-mentioned alignment pin also can be four, promptly increases by two alignment pins 61, and they are positioned at the position of the staight shank suspension hook coupler body outside near pedestal, and this moment, staight shank suspension hook coupler body end did not contact with the side of pedestal 1.
In order to increase the rigidity of anchor clamps, be provided with gusset 9 between pedestal 1 and the backing plate 3, the gusset 9 of this example is two.
The assembly of these anchor clamps clamping staight shank suspension hook as shown in Figure 4.When producing in batches, be that first pedestal 1 with these anchor clamps is clamped on the scroll chuck of lathe, adjust the center, then the staight shank suspension hook is contained on these anchor clamps, carry out screw thread processing.
