Description

The valve rod seat ring pressure riveting device of heavy electric control EGR valve seat
Technical field:
The utility model belongs to field of fixtures, is related to a kind of valve rod seat ring pressure riveting device of heavy electric control EGR valve seat.
Background technology:
In the assembling production of electric control EGR, it is related to valve rod seat ring and presses this procedure, traditional pressure riveting device manually enters Row feeding presses, and has the following disadvantages:First, labor intensity is big during artificial feeding, with the propulsion of working time, operator It is easily tired, and it is also easy to produce maloperation for the part for having positive cross-demand assembling;Second, artificial feeding and then machine press and are difficult to Ensure the axiality in seat ring and seat ring hole, while without monitoring in real time, easily cause press it is insecure.We pass through test of many times With improvement, a kind of valve rod seat ring pressure riveting device of heavy electric control EGR valve seat is developed, above mentioned problem is efficiently solved.
Utility model content:
Technical problem to be solved in the utility model is:A kind of valve rod seat ring of heavy electric control EGR valve seat is provided to press Device, effectively solves valve seat clamping once, is pressed process with regard to that can complete the whole of valve rod seat ring.
To achieve the above objectives, the technical solution adopted in the utility model is as follows:
The valve rod seat ring pressure riveting device of heavy electric control EGR valve seat, including:C-form stand, gas-liquid pressure-boosting in hydraulic means Cylinder, pressure head and die switching cylinder, pressure sensor, displacement transducer, pressure head, probe, die;Length in machinery positioning fixture Square chuck body, great circle position pin, roundlet position pin, two active grabs;Pneumohydraulic pressure-cylinder, pressure head and die switching cylinder and length Square chuck body is fixed on C-form stand;Pressure sensor be arranged on pneumohydraulic pressure-cylinder and pressure head and die switching cylinder it Between.
The bottom that pressure head switches cylinder with die is provided with displacement transducer, pressure head, probe and die.
Great circle position pin, roundlet position pin and two active grabs are installed with rectangle chuck body.
The utility model can reach following beneficial effect after using above technical scheme:During valve rod seat ring presses, Efficiently solve valve seat clamping once, just can complete the process that presses of valve rod seat ring, and there is during pressing valve rod seat ring Positive and negative mistake proofing identification function, while ensure that the axiality of seat ring and seat ring hole, and has line pressure shift monitoring device, realizes valve Pole socket circle riveting fast reliable.
Brief description of the drawings:
Fig. 1 is the structural representation of the valve rod seat ring pressure riveting device of the heavy electric control EGR valve seat of the utility model;
Fig. 2 is that the machinery positioning clamp structure of the valve rod seat ring pressure riveting device of the heavy electric control EGR valve seat of the utility model shows It is intended to;
Fig. 3 is the structural representation of the valve rod seat ring pressure riveting device pressure head of the heavy electric control EGR valve seat of the utility model;
Fig. 4 is the structural representation of the valve rod seat ring pressure riveting device die of the heavy electric control EGR valve seat of the utility model;
Embodiment:
Referring to accompanying drawing 1-4, the utility model is described in further detail.The valve rod seat ring of heavy electric control EGR valve seat presses dress Put, including hydraulic means, machinery positioning fixture two parts:Hydraulic means:C-form stand 1, pneumohydraulic pressure-cylinder 2, pressure head and die Switch cylinder 3, pressure sensor 4, displacement transducer 5, pressure head 6, probe 7, die 8;Machinery positioning fixture:Including rectangular clevis Have body 10, great circle position pin 11, roundlet position pin 12, two active grabs 13;
Pneumohydraulic pressure-cylinder 2, pressure head and die are switched cylinder 3 and machinery by C-form stand 1 as main body of the present utility model Rectangle chuck body 10 in positioning fixture is fixed by screws in thereon;Pressure sensor 4 is fixed on pressure head and cut with die The top half of ventilation cylinder 3, while displacement transducer 5, pressure head 6, probe 7, die 8 are sequentially fixed at into pressure head and die switching The latter half of cylinder 3;Great circle position pin 11, roundlet position pin 12 are interference fitted with the macropore in rectangle chuck body 10, aperture, Two active grabs 13 are fixed by screws in rectangle chuck body 10.
Before operation starts, great circle position pin 11, roundlet position pin 12 in rectangle chuck body 10 are inserted in 9 two holes of valve seat In, the rotary freedom of valve seat 9 is limited, the handle of two active grabs 13 is then pulled downwards, valve seat 9 is firmly fixed In chuck body 10;Pressure head 6 uses vacsorb valve rod seat ring, and probe 7 has the identification positive and negative error-disable function of valve rod seat ring, gas Liquid pressurized cylinder 2 provides 5t power press-in valve rod seat ring;Then mobile pressure head switches cylinder 3 with die, with die 8 to valve rod seat ring Carry out riveting at 8, during pressing, pressure sensor 4 is monitored in real time with displacement transducer 5, pressure head 6 and die 8 by Pressure head switches with die switching cylinder 3.
By above example as can be seen that the utility model is a kind of valve rod seat ring dress to heavy electric control EGR valve seat Folder once, just can complete the process that presses of valve rod seat ring, and have the positive and negative mistake proofing identification function of valve rod seat ring during pressing, together When ensure that the axiality of seat ring and seat ring hole, and have line pressure shift monitoring device, realize valve rod seat ring riveting fast reliable.
