Description
Technical field
The utility model relates to a kind of press-fitting tool that is used for connecting bolt.
Background technology
The general suspension of Hyundai Motor is made up of flexible member, guiding mechanism, shock absorber and QS, and the shock absorber strut assembly in the suspension just to be connected and must to finish by connecting bolt with vehicle body in order to realize.So in order effectively shock absorber and vehicle body to be coupled together, just the knurled segment on the connecting bolt of all size that must different automobile types is required, model and quantity relies on interference fit to be pressed in the hole of the outer adapter sleeve that cooperates with it, makes it fixing.
Be pressed into for knurled segment in the hole of outer adapter sleeve connecting bolt, be extensive use of press-fitting tool as shown in Figure 1 at present, it comprises die shank 12, be fixed in pressure head 13, base plate 14 on the die shank 12, be fixed in die shoe 15 on the base plate 14, be fixed in the counterdie 16 on the die shoe 15, and die shoe 15 and counterdie 16 are equipped with centre bore; During use, the operator earlier puts connecting bolt 17 in the hole on the outer adapter sleeve 18, and then connecting bolt 17 is put in the hole of aligning counterdie 16; At this moment, foot pedal starts hydraulic press, and the hydraulic press piston rod drives pressure head 13 and down move, until the upper surface of arrival connecting bolt 17, treat pressure reach set press-fit pressure after, the backhaul of hydraulic press piston rod press-fits and finishes, and takes off workpiece; The shortcoming that above press-loading process device exists is: a, pressure head 13, counterdie 16 location are bad, occur crookedly easily, have influenced product quality; B, because the knurled segment of connecting bolt 17 is little matched in clearance with the centre bore of counterdie 16, make that being pressed into the back bolt is not easy taking-up, it is all very hard that the operator gets material at every turn, material returned difficulty, production efficiency are not high.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of connecting bolt press-fitting tool is provided, and it has the good product quality that processes, the advantage of the automatic material returned, has improved production efficiency.
For achieving the above object, connecting bolt press-fitting tool of the present utility model, comprise die shank, be fixed in pressure head, base plate on the die shank, be fixed in die shoe on the base plate, be fixed in the counterdie on the die shoe, die shoe and counterdie are equipped with centre bore, it is characterized in that on described die shank, being fixedly connected with cope match-plate pattern, described base plate is provided with centre bore, that slides in centre bore is provided with push pedal, cope match-plate pattern is connected by two studs that pass die shoe with push pedal, one push rod is set in push pedal, and the upper end of push rod is positioned at the centre bore of die shoe and counterdie.
During use, to earlier connecting bolt be put in the hole of outer adapter sleeve, put into again in the centre bore of counterdie, step on pedal, the hydraulic press piston rod drives pressure head, cope match-plate pattern, stud, push pedal and push rod down move, after pressure head touches the connecting bolt upper surface, treat that pressure reaches setting postpone, after the knurled segment of connecting bolt is pressed into outer adapter sleeve fully, the part of connecting bolt is arranged in the centre bore of counterdie at this moment, stud drives push pedal during the backhaul of hydraulic press piston rod, push rod ejects connecting bolt from counterdie, the operator takes out workpiece, wholely press-fits process and finishes; Because the accurate positioning of pressure head, counterdie, the good product quality that processes, and the material returned have automatically improved production efficiency;
As further improvement of the utility model, die shoe and push rod are provided with the shoulder that matches; In the time of can preventing that stroke is long, push rod comes off from die shoe;
In sum, the utlity model has the good product quality that processes, the advantage of the automatic material returned, improved production efficiency.

Fig. 2 is the front view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 2, this connecting bolt press-fitting tool, comprise die shank 1, be fixed in the pressure head 2 on the die shank 1, base plate 3, be fixed in the die shoe 4 on the base plate 3, be fixed in the counterdie 5 on the die shoe 4, die shoe 4 and counterdie 5 are equipped with centre bore, on described die shank 1, be fixedly connected with cope match-plate pattern 6 by screw, described base plate 3 is provided with centre bore, that slides in centre bore is provided with push pedal 7, cope match-plate pattern 6 is connected by two studs 8 that pass die shoe 4 with push pedal 7, one push rod 9 is set in push pedal 7, the upper end of push rod 9 is positioned at the centre bore of die shoe 4 and counterdie 5, and die shoe 4 and push rod 9 are provided with the shoulder that matches.
During use, to earlier connecting bolt 10 be put in the hole of outer adapter sleeve 11, put into again in the centre bore of counterdie 5, step on pedal, the hydraulic press piston rod drives pressure head 2, cope match-plate pattern 6, stud 8, push pedal 7 and push rod 9 down move, after pressure head 2 touches connecting bolt 10 upper surfaces, treat that pressure reaches setting postpone, after the knurled segment of connecting bolt 10 is pressed into outer adapter sleeve 11 fully, the part of connecting bolt 10 is arranged in the centre bore of counterdie 5 at this moment, stud 8 drives push pedal 7 during the backhaul of hydraulic press piston rod, push rod 9 ejects connecting bolt 10 from counterdie 5, the operator takes out workpiece, wholely press-fits process and finishes; Because the accurate positioning of pressure head 2, counterdie 5, can not occur crookedly, the good product quality that processes, and the material returned have automatically improved production efficiency.
