Abstract
The utility model provides chuck jaws for vertical lathes comprising clamping jaws, a screw, chuck jaw seat, etc. Concerning the utility model, a pad and an adjusting mat are arranged on both ends of the screw, so the chuck jaw seat changes into an anti-abrasive element, because of the advantage of the axial clearance of the screw which is easy to adjust, the repair cost of the chuck jaws is reduced greatly, and the service life of the chuck jaws is enhanced. The utility model is applicable to vertical lathes with various medium and small types, and can replace with the existing chuck jaws.
Description
The utility model belongs to a kind of chuck jaw structure of middle-size and small-size vertical lathe accessories section.
Existing vertical lathe chuck jaw is made up of claw, screw rod and chuck jaw seat, and screw rod is meshed with the screw thread of claw, and the screw thread end of screw rod directly contacts with the bearing face of chuck jaw seat part.Adopt the chuck jaw of this structure, when the screw drive claw,, thereby the chuck jaw seat of generally being made by the nodular cast iron material is is very easily worn and torn at its bearing face owing to the chuck jaw seat directly contacts with screw rod, and bear its axial compressive force.Though the inevitable outcome that conventional measure brought that this phenomenon is taked in order to protect screw rod in Machine Design; but when wearing and tearing reach a certain amount of; because the end play between the bearing face of screw rod screw thread two ends and chuck jaw seat is excessive, causes chuck jaw normally not use.In order to address this problem, the unique measure that can take at present is exactly the bearing face part of repairing the chuck jaw seat, but this is not thing easily concerning the user, thereby the chuck jaw seat that often more renews when the generation said circumstances.This shows that the vertical chuck jaw of said structure in use because the concentrated wear of chuck jaw seat is scrapped the higher chuck jaw seat of cost, causes the cost of repairs of chuck jaw to improve greatly.
In view of the existing not enough point of above-mentioned chuck jaw, the utility model desires to provide a kind of end play of easy adjustment screw rod, can improve the chuck jaw novel vertical chuck jaw in service life.
The vertical lathe chuck jaw that the utility model is provided for achieving the above object is made up of claw, screw rod, lining, alignment pin, adjusting pad and chuck jaw seat.According to shown in Figure 1, the screw thread of claw (4) still meshes with screw rod (5), the two ends of the screw rod between screw rod and the chuck jaw seat (6) are provided with lining (1), one end of this lining is directly contacted with the screw thread end of screw rod, and fix with alignment pin (2) between its waist and chuck jaw seat in order to prevent that lining from rotating with screw rod on the one hand, for the end play of adjusting screw rod adjusting pad (3) is set between the boss of chuck jaw seat and lining on the other hand.According to Fig. 2, shown in Figure 3, lining is made semi-circular structure, at its waist hole (7) is set, and the material of lining also can adopt the little materials of hardness such as nodular cast iron.Adjusting pad both can adopt packing ring commonly used, also can be made into semi-circular packing ring.The utility model in use, along with the contacted end wear of lining and screw rod screw thread end, also corresponding increase adjusting pad; When the liner wear amount acquires a certain degree, the lining that more renews.
The utility model makes the chuck jaw seat become not wear-out part according to the vertical lathe chuck jaw that said structure provided because of setting up lining and adjusting pad, can increase substantially the service life of chuck jaw, and makes the easier adjustment of end play of screw rod.The utility model all can be applicable to single-column, the middle-size and small-size vertical lathe of twin columns, alternative existing chuck jaw.
Embodiment of the present utility model:
According to shown in Figure 4, composition and Fig. 1 of claw (8), screw rod (9), lining (11), alignment pin (12), adjusting pad (13) and chuck jaw seat (10) are similar, lining is then according to Fig. 5, employing full circle type boss structure shown in Figure 6, and its waist is provided with hole (14) adjusting pad and also correspondingly adopts full circle type packing ring.The chuck jaw of this structure is suitable for small-sized lathe.
