Abstract
The utility model discloses a screw bolt pressing and installing device, which comprises an upper mold and a lower mold, wherein the upper mold comprises an upper template and a press head, an assembly hole group for assembling the press head is arranged on the upper template, a sealed liquid state force transmission medium passage communicated with the bottom of each assembly hole is also arranged on the upper template, the lower mold comprises a lower template, and an anti-interference hole allowing a screw bolt to pass is arranged on the lower template. The screw bolt pressing and installing device is characterized in that liquid state force transmission media are fully filled in the liquid state force transmission media passage, so the pressure exerted by the liquid state force transmission media on each press head during the screw bolt pressing and installing is identical, and the balanced stress of each screw bolt can be ensured. In addition, in the pressing and installing process, the press head and the hydraulic force transmission media adopt non-rigid contact, and the press head can float a certain distance in the depth direction of the assembly holes, so the dimension errors between different screw bolts can be overcome, the goal of simultaneously pressing and mounting several screw bolts for transmission is realized, and a plurality of screw bolts can be enabled to be simultaneously pressed and installed to proper positions.
Description
Technical field
The utility model relates to a kind of automotive brake assembling device, particularly a kind of device that press-fits the automotive brake bolt.
Background technology
In the assembling process of automotive brake, need a kind of device that press-fits bolt usually, several bolts are carried out interference be pressed into.Should guarantee several bolt strained equilibriums when press-fiting, guarantee that again several bolts are press-fit into place, not occur leakage simultaneously and press-fit phenomenon.
Several kinds of pressing methods and pluses and minuses thereof:
1, single press-fits method one by one.Though single press-fits and can guarantee that several bolt pressures are balanced, press-fit like this and have the shortcoming that beat is slow, production efficiency is low, be unfavorable for producing in enormous quantities.
2, several bolt while rigidity press-fit method.Can make to press-fit beat and significantly improve, enhance productivity greatly.But, bolt when press-fiting, can occur and press-fit situation not in place because parts such as bolt itself have certain foozle.In addition, owing to be that several bolts press-fit simultaneously, the situation of neglected loading bolt can appear in operator once in a while, causes bolt to leak and press-fits.
To above-mentioned deficiency, need a kind of press mounting tool of design, can guarantee several bolt strained equilibriums, satisfy and produce in enormous quantities, can guarantee that again every bolt all is press-fit into place, bolt also can not occur and leak situation about press-fiting.
The utility model content
In view of this, the purpose of the utility model provides a kind of bolt press-loading apparatus, and it can press-fit many bolts simultaneously, can guarantee bolt strained equilibrium again simultaneously, and bolt is press-fit into place; Can also avoid the neglected loading bolt.
The utility model bolt press-loading apparatus comprises upper die and lower die;
Said patrix comprises cope match-plate pattern and the pressure head of pressing bolt; Cope match-plate pattern is provided with the pilot hole group of assembling pressure head; Said pressure head is arranged in each pilot hole and with its slipper seal and cooperates; Be provided with also on the said cope match-plate pattern that the restriction pressure head skids off the position limiting structure of pilot hole and the liquid power transmission medium channel of the sealing that is communicated with each pilot hole bottom, being full of in the said liquid power transmission medium channel has liquid power transmission medium;
Said counterdie comprises lower bolster, and said lower bolster is provided with the anti-interference hole that supplies bolt to pass.
Further, the hole wall in said anti-interference hole is provided with and is used for surveying anti-proximity transducer of interfering the hole whether to have bolt;
Further, said pressure head is provided with limited step, said position limiting structure be coated at pressure head and be fixed on the cope match-plate pattern the collar, the end face of said limited step leans against on the collar;
Further, the hole wall of said pilot hole is provided with the sealing ring that is sealed and matched with pressure head;
Further, the passage oral area of said liquid power transmission medium channel is provided with and seals bolt.
The beneficial effect of the utility model: the utility model bolt press-loading apparatus; Because in liquid power transmission medium channel, being full of has liquid power transmission medium; Therefore the pressure that liquid power transmission medium is applied on each pressure head when press-fiting bolt equates, thereby can guarantee each bolt strained equilibrium; And in press-fiting process; Between pressure head and the liquid power transmission medium is non-rigid contact, and pressure head can be along the pilot hole depth direction certain distance that floats, thereby can remedy the scale error between different bolts; Play the purpose that press-fits many bolts simultaneously, and guarantee that many bolts are press-fit into place simultaneously; And because lower bolster is provided with to be used for surveying to prevent whether the interference hole exists the proximity transducer of bolt, thereby can avoid the situation of neglected loading bolt in press-fiting process.
