Description

The dedicated drill point mould of extension bar

Technical field

The utility model relates to a kind of mold device, specifically a kind of dedicated drill point mould of extension bar.

Background technique

During producing certain same type hydraulic shield support, the extension bar quantity of jack is more, of large quantities, Drill bad positioning on cylinder, also can not guarantee that the concentricity at hole center Yu spreading rod axis, the size between each hole are also difficult Guarantee.Also lack Special mould at present, the qualification rate of product is only controlled by the technical level of operator, equipment cutter is caused to damage Consumption is big, and Product Precision cannot be effectively ensured.

Summary of the invention

Problem exists in the prior art purpose of the utility model is to solve above-mentioned, and it is dedicated to provide a kind of extension bar Drill point mould.

The utility model is achieved by the following technical solution：

A kind of dedicated drill point mould of extension bar, including rectangular substrate, one of long side side end of rectangular substrate Place is extended outward at least two spaced otic placodes, and screw rod is vertically and fixedly provided on otic placode, is threaded on screw rod up and down Two nuts, the position on screw rod between upper and lower two nuts are gripped with U-shaped iron；Along above-mentioned long side on rectangular substrate Position be fixed with the L-type drilling frames of several spaced sets, L-type drilling frame is staggeredly arranged with otic placode, and L-type drilling frame includes The riser fixed vertical with rectangular substrate, direction of the top of riser right above rectangular substrate are vertically and fixedly provided with transverse slat, The center of transverse slat is equipped with the round buss through transverse slat, and the center positioned at the riser of the L-type drilling frame of most side end is pacified Equipped with the round buss for running through the riser；The position of face otic placode is fixed with along rectangular substrate short side edge direction on rectangular substrate The v block of setting.

In clamping workpiece on the utility model mould, workpiece is packed into from the long side face of mould, so that workpiece is placed in V In the V-shaped groove of sections, v block plays support positioning action, then adjusts position of the U-shaped iron on screw rod, so that U-shaped iron compresses work Part, fixed U-shaped iron.Make located lateral size using the round buss on the transverse slat of L-type drilling frame, then spitting drill in round buss Head first processes one head bore of extension bar and by 90 ° of workpiece rotation, passes through the round buss on the riser of L-type drilling frame after processing is completed Position workpiece, so that remaining hole beaten will be needed to position on workpiece, ensure that in this way 90 ° of two rounds vertically.This The use of utility model mould effectively improves the machining accuracy of drilling, is increased to error within 0.2mm by 0.5mm, hangs down Straight degree is guaranteed, and has not only increased working efficiency but also has reduced labor intensity.

It is as a preferred technical solution, releasable connection between the riser and transverse slat of L-type drilling frame, specially：Riser It is opened up on top surface there are two screw hole, the position of corresponding two screw holes opens up that there are two be arranged along transverse slat length direction respectively on transverse slat Sliding slot, two fastening bolts are screwed in two screw holes on riser after passing through two sliding slots on transverse slat, thus by riser It is fastened with transverse slat.Releasable connection is set by the riser of L-type drilling frame and transverse slat, transverse slat can be thus finely adjusted, is protected The center line for demonstrate,proving the round buss on multiple transverse slats is consistent, reduces the trueness error of clamping error, measurement error and fixture, into one Step improves machining accuracy.

At least two spaced transition platess, transition plates are fixed on rectangular substrate as a preferred technical solution, Be arranged along rectangular substrate short side edge direction, another long side side end of the free end of transition plates beyond rectangular substrate and from By being fixed with acclivitous block on end；Part corresponding with v block position is designed in transition plates for slot, slot it is minimum Point is lower than the V-shaped groove minimum point of v block.The purpose that transition plates is arranged is to be easy for workpiece to be packed into the v block of the utility model, Specifically workpiece is first lifted to be placed in two transition platess, can take advantage of a situation along transition plates for workpieces processing enter V in this way On the position of sections, assembly work is made to become smooth；The purpose of transition plates free end setting block be in order to prevent workpiece from tire It is rolled down on tool, improves safety；In transition plates the minimum point of slot be lower than v block V-shaped groove minimum point, in this way design be for Workpiece can be allowed to be completely supported on v block, facilitate process operation.

Be respectively fixed with baffle at the two sides short side of rectangular substrate as a preferred technical solution, prevent workpiece from It is slid in mould, secondly the effective length between two side baffles has been also the length dimension of extension bar, is eliminated on length direction The positioning marking in hole has advanced optimized the structure of mould.

The utility model mould is suitable for the processing of each pores of porous extension bar class product on one face, this is practical Novel mould is easy to operate, using flexible, reduces artificial scribing line error, dimensional accuracy has been effectively ensured.The utility model tire The application of tool effectively improves labor productivity, alleviates the labor intensity of worker, reduces the abrasion of cutter, produce simultaneously Product precision is guaranteed, and improves the quality of product.
