Description

Sheath pressing-in jig

Technical field

The present invention relates to a kind of tool that sheath is pressed into grease gun.

Background technology

Grease gun is widely used at mechanical field, uses grease gun just can very easily butter be joined on the mechanical part.The gun barrel of grease gun is because be metal material and more sliding, when inevitably dripping on the outer surface when butter is arranged, will become more sliding and unfavorable with the controlling of staff, therefore, the general soft sheath that can be locked with gun barrel that puts on the gun barrel of grease gun is as the PVC sheath.Because sheath is softer, not easy to operate when by hand sheath being put gun barrel, and manual efficient is low.

Summary of the invention

Technical problem to be solved by this invention provides a kind of sheath pressing-in jig, can sheath be pressed on the gun barrel of grease gun very easily, has improved the efficient that is pressed into of sheath.

For solving above technical problem, the present invention takes following technical scheme:

A kind of sheath pressing-in jig, it comprises:

Operating desk, operating desk are provided with the fixed part of the gun barrel that is used for fixing grease gun; Lead, an end of lead is fixedly installed on the operating desk, offers gas passage on the lead; Pipe box, pipe box are set on the lead slidably; Power set, power set are fixedlyed connected with pipe box, are used to drive pipe box along its axially-movable;

The axial line of gun barrel, lead and pipe box coincides, gun barrel removably is connected with the wedge that external diameter diminishes gradually near on the end of lead, lead has the tapered end that diminishes gradually towards the direction diameter of gun barrel near an end of gun barrel, the leading section of pipe box has the aperture and becomes big accepting hole, is formed with the slit that can accommodate sheath between the inwall of accepting hole and the outer surface of tapered end.

Power set comprise the cylinder that is fixedly installed on the operating desk downside, the grip block of fixedlying connected with pipe box, and cylinder comprises cylinder body, is inserted in the interior piston rod of cylinder body slidably, and piston rod is fixedlyed connected with grip block.

Operating desk is provided with the guide rail that extends along the direction of axis line of gun barrel, and fixed part is slidably disposed on the guide rail, is provided with between fixed part and the operating desk to make fixed part and the relatively-stationary locking mechanism of operating desk.The bearing of trend of gas passage parallels with the axial line of lead.

Lead has tapered end, and on an end of gun barrel, be connected with wedge, thereby can very easily sheath be enclosed within on the tapered end and wedge of lead, and surround air chamber between lead, wedge, the sheath, can in air chamber, inflate expansion thereby soft sheath is stressed by the gas passage on the lead; Because an end of sheath is to be plugged in the slit of pipe box and tapered end formation, after the jacket expansion, will tighten mutually with the inwall of pipe box, at this moment, when power set drive pipe box travels forward, will promote sheath and move forward on the gun barrel.

Because the utilization of technique scheme, the present invention has the following advantages:

Utilize this sheath pressing-in jig, need not manpower, just can very easily sheath be pressed on the gun barrel of grease gun, sheath be pressed into the efficient height.

The specific embodiment

As shown in Figures 1 to 4, the right side of operating desk is the place ahead among Fig. 1.Power set 2, the end that sheath pressing-in jig according to present embodiment mainly comprises operating desk 1, be fixedly installed on the downside of operating desk 1 is fixedly installed on lead 3 on the operating desk 1, is set in pipe box 4, wedge 6 on the lead 3 slidably.

The table top of operating desk 1 front side is provided with fixed part 10, the leading section of gun barrel 9 is fixed on the fixed part 10, and the front side portion of operating desk 1 is provided with guide rail 12, and the bearing of trend of guide rail 12 parallels with the axial line of gun barrel 9.Between fixed part 10 and operating desk 1, be provided with and make fixed part 10 and operating desk 1 relatively-stationary locking mechanism.When locking mechanism was in released state, fixed part 10 can slide along guide rail 12.

Removably be connected with wedge 6 on the rearward end of gun barrel 9, wedge 6 is a truncated cone-shaped, and the diameter of wedge 6 rearward diminishes gradually from the rearward end of gun barrel 9.

The table top of the rear side of operating desk 1 is provided with support, and an end of lead 3 is fixedly installed on this support, and the axial line of lead 3 overlaps with the axial line of gun barrel 9.Lead 3 has the tapered end 31 that diameter reduces gradually towards an end of gun barrel 9, and lead 3 also coincides with the axial line of wedge 6, and keeps certain spacing between lead 3 and the wedge 6.One end of sheath 11 tightly is enclosed within on the wedge 6, and its other end is enclosed within on the tapered end 31, and sheath 11, wedge 6, tapered end 31 threes surround an air chamber 7.

Pipe box 4 is set on the lead 3 slidably, and the axial line of the axial line of pipe box 4 and lead 3 coincides.The leading section of pipe box 4 has the aperture and becomes big accepting hole 40, be formed with the slit 5 that to accommodate sheath 11 between the outer surface of the inwall of accepting hole 40 and tapered end 31, make sheath 11 when putting tapered end 31, insert in the slit 5, the other end of sheath 11 is enclosed within on the wedge 6, and is provided with wedge 6 sealings.On lead 3, offer the gas passage 30 that axially connects along it, two road junctions of gas passage 30 are connected with extraneous air feed equipment and air chamber 7 respectively, so just can in air chamber 7, charge into gas by gas passage 30, thereby soft sheath 11 will be stressed and expand, sheath 11 after the expansion with turgor slit 5, and with the inwall of pipe box 4 chucking, simultaneously, the oral area of the other end of sheath 11 expands and becomes big, when pipe box 4 travels forward, will successfully sheath 11 be pressed on the gun barrel 9.

Power set 2 specifically comprise cylinder 20, the grip block 8 of fixedlying connected with pipe box 4.Cylinder 20 comprises cylinder body 200, is inserted in piston rod 201 in the described cylinder body 200 slidably, grip block 8 is fixedlyed connected with piston rod 201, operating desk 1 is provided with the gathering sill that fore-and-aft direction extends, and grip block 8 seesaws at the drive lower edge of piston rod 201 gathering sill.

Pipe box 4 is fixedly connected with power set 2, can seesaw under the effect of power set 2.After air chamber 7 inflations, the oral area that sheath 11 is enclosed within on the wedge 6 becomes big, restarts power set 2, piston rod 201 travels forward, drive pipe box 4 and travel forward, pipe box 4 will drive sheath 11 and move forward on the rifle 9, successfully sheath 11 is pressed on the gun barrel 9.

In sum, utilize the press-in device of this sheath, need not manpower, just can very easily sheath be pressed on the gun barrel of grease gun, sheath be pressed into the efficient height.
