Abstract
The invention relates to a draw hook for disassembling a small belt pulley a shuttleless loom, which comprises a draw hook seat which is plugged into an opening of the belt pulley, a screw rod which is connected with the draw hook seat and a handle which is fixed on the screw rod, wherein the inner wall of the opening of the draw hook seat is provided with a pull block, the pull block is projected towards the inner side of the draw hook seat along the radial direction of the screw rod, and a magnetic column is installed on the draw hook seat. The draw hook seat is sleeved on the belt pulley, so the pull block is plugged inside a race of the belt pulley, the pull block can be rotated for a proper angle along the race of the belt pulley according to the requirement, so the pull block arrives at the position of the draw hook seat on which the magnetic column is installed, the pull block is absorbed by the magnetic column, and then the handle is rotated so as to remove off the belt pulley. The draw hook has simple structure, is convenient and practical, solves the disassembling problem of the small belt pulley of the shuttleless loom, and is very simple to use.
Description
Technical field
The present invention relates to a kind of instrument of dismantling belt pulley, refer in particular to the instrument of employed small belt pulley on the dismounting shuttleless loom.
Background technology
Because fabric organize conversion, shuttleless loom is often wanted the conversion machine speed, and the belt pulley that is used for transmission just need be adjusted accordingly, and promptly pulls down former belt pulley, changes suitable belt pulley.At present in art technology, the dismounting belt pulley uses drag hook to carry out usually, and because the suffered restriction in locus, and when the diameter of belt pulley during less than 90 millimeters, general drag hook cannot be held belt pulley, also just can't dismantle this small-sized belt pulley.Therefore, those skilled in the art need seek a kind of specific purpose tool that can dismantle the small belt pulley on the shuttleless loom.
Summary of the invention
The object of the invention will provide a kind of drag hook exactly, employed small belt pulley on its detachable shuttleless loom.
Technical scheme of the present invention provides a kind of draw hook for disassembling small belt pulley of shuttleless loom, comprise drag hook seat, be connected screw rod on the drag hook seat, be fixed on the handle on the screw rod with the opening that is used to insert belt pulley, the inwall of the opening part of drag hook seat is provided with pulling block, pulling block radially protrudes towards the inboard of drag hook seat along screw rod, and the magnetic post is installed on the drag hook seat.On belt pulley, pulling block is inserted in the race of belt pulley the drag hook cover for seat, pulling block is moved an angle along the race of belt pulley, make pulling block arrive the position that the magnetic post is installed of drag hook seat, hold pulling block by the magnetic post, swing handle just can unload belt pulley then.
Preferably, there is a side surface can be processed into taper shape on the part that protrudes from the drag hook seat of pulling block, on this trochoidal surface, can adheres to cushion.Be processed into conical surface and on this surface, adhere to cushion, can guarantee that this side surface of pulling block contacts well with the groove face of belt pulley, makes that the pressure on the contact-making surface reduces.
More optimally, the conical surface on the pulling block is preferably 34～38 degree with respect to screw rod gradient radially.
In a kind of more particular embodiment, pulling block can be along the radiai adjustment position of screw rod.After pulling block radially regulated, the size that can adapt to belt pulley changed by a small margin, and the pulling block that need not more to renew uses.
Further, the magnetic post that is installed in the opening part of drag hook seat can have a plurality of, like this, put into the race of belt pulley at pulling block after, just can make the contraposition of magnetic post as long as rotate a low-angle, its adaptability is stronger, uses more easy.
The present invention compared with prior art has following advantage: drag hook simple in structure, convenient and practical solved the dismounting problem of the small belt pulley of shuttleless loom, and used fairly simple.
Description of drawings
Accompanying drawing 1 is the side view according to a kind of drag hook of the invention process;
Accompanying drawing 2 is the main cutaway view of drag hook shown in Figure 1;
Wherein: 1, handle; 2, screw rod; 3, drag hook seat; 4, pulling block; 41, coned face; 5, cushion; 6, magnetic post; 7, belt pulley; 8, motor.
The specific embodiment
Belt pulley generally all uses drag hook to dismantle, and especially the belt pulley of using on the shuttleless loom owing to the conversion of fabric tissue, often will use the drag hook dismounting, the belt pulley that more renews then.And drag hook provided by the invention is mainly used in the small belt pulley on the dismounting shuttleless loom, below in conjunction with accompanying drawing and specific embodiment content of the present invention is described in detail, for the part identical with conventional art, only adopt identical title, explain that no longer in detail emphasis improvement of the present invention part elaborates.
Embodiment as shown in Figure 1, this figure has reflected the structure diagram according to a kind of drag hook of the invention process, as can be seen from the figure, drag hook mainly is made of handle 1, screw rod 2, drag hook seat 3 and pulling block 4, cutaway view as shown in Figure 2, handle 1 is fixed together with screw rod 2, and 2 of screw rods are connected on the drag hook seat 3, the end of drag hook seat 3 has opening, and pulling block 4 is installed on the wall of this opening part.
Pulling block 4 radially protrudes towards the inboard of drag hook seat 3 along screw rod 2, when using drag hook to tear small belt pulley open, as shown in Figure 3, drag hook seat 3 utilizes opening sleeve on the belt pulley on the output shaft that is connected in motor 87, have race on the belt pulley 7, the part that protrudes from drag hook seat 3 of pulling block 4 is promptly inserted in the race on the belt pulley 7, on the part in the race of this insertion belt pulley 7, the outer surface of pulling block 4, particularly the side will contact with the cell wall of the race of belt pulley 7, and coned face 4 is processed in one of them side, and this coned face 4 is preferably in 34～38 degree with respect to screw rod 2 angle of inclination radially, sticking one deck elastomeric material on this coned face 41, form cushion 5, as shown in Figure 2, can guarantee that like this this side surface that is stained with cushion 5 contacts well with the wheel cell wall of belt pulley 7, reduces the pressure of contact-making surface.
Pulling block 4 generally has two kinds of specifications to use for replacing, and pulling block 4 is preferably being provided with along the mode of the radiai adjustment position of screw rod 2, to enlarge the scope of application of drag hook, in general, can to dismantle diameter be small belt pulleys in 70～90 millimeters scopes to drag hook implemented according to the invention.
Magnetic post 6 is installed on the drag hook seat 3, and magnetic post 6 is preferably a plurality of, and installs in the mode of interval certain angle.When using drag hook, magnetic post 6 is just brought into play its magnetic action, makes that pulling block 4 is held, and pulling block 4 is positioned in the race of belt pulley 7.
Fig. 2 has reflected the using method of drag hook dismounting belt pulley 7, drag hook seat 3 is enclosed within on the belt pulley 7 from opening part, pulling block 4 is put into the race of belt pulley 7 from the opening part of drag hook seat 3, rotate an angle then, make the part that the magnetic post is housed of drag hook seat 3 arrive suitable position,, dismantle according to the conventional method then with the relative belt pulley of drag hook 7 location, be swing handle 1, so that belt pulley 7 is unloaded.Whole unloading process is very simple, and the pulling block 4 by having cushion 5 and the associating of magnetic post 6, makes that operation is reliable, and for the small-sized belt pulley that usually uses on the shuttleless loom, practicality is very strong.
More than specific embodiment of the present invention is illustrated in conjunction with diagram; but protection content of the present invention is not only limited to above embodiment, in affiliated technical field of the present invention, and the common knowledge of a GPRS; just can in its technology main idea scope, carry out diversified change.
