Abstract
The utility model discloses an automatic gas vent punching device for a base core of an automobile engine cylinder block. The automatic gas vent punching device comprises positioning devices and pneumatic drills, wherein drill bits of the pneumatic drills extend upwards to realize the work of punching sand cores; a mounting plate is arranged; the positioning devices are used for positioning the sand cores; a hoisting air cylinder is used for adjusting the heights of the pneumatic drills; the whole device is simple in structure and convenient to maintain; the plurality of sand cores can be punched once and the punching efficiency can be improved.
Description
Technical field
The utility model relates to casting field, especially a kind of device to core punching.
Background technology
Automobile engine cylinder-body is typical complex thin-wall ironcasting.In the cylinder body of producing at present, need to beat steam vent in Xin Jiao position, the basic core back side, meet the needs of cylinder pouring technique, jacket core air pressure inside while reducing cast, the coating on the hypertonia bursting core surface that prevents from getting angry in core, produces casting defect.If employing Manual punching, wastes time and energy, can not meet the efficiency of batch production.
Therefore, need a kind of new technical scheme to address the above problem.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, provides a kind of and automatically beats vent device for automobile engine cylinder-body basis core, can improve the perforating efficiency of core being beaten to steam vent.
For realizing above-mentioned utility model object, the utility model is beaten vent device automatically for automobile engine cylinder-body basis core can adopt following technical scheme:
For automobile engine cylinder-body basis core, automatically beat a vent device, comprise housing, be covered in cover plate on housing, be installed on a pair of positioner on cover plate, be positioned at housing lift cylinder, connect lift cylinder laterally extending installing plate, be fixed on cover plate inner side and extend through the guide posts of installing plate downwards; Described cover plate is provided with opening, and described a pair of positioner is located at respectively opening both sides; Installing plate is provided with some pneumatic drills, and the drill bit of described pneumatic drill extends upward, when installing plate rising drill bit is through opening.
Compare with background technology, the utility model is realized the drilling operation to core by pneumatic drill is set, and installing plate positioner location core (basic core) is set, use lift cylinder to regulate the height of pneumatic drill, whole apparatus structure is simple, be convenient to safeguard, and can once to a plurality of cores, carry out drilling operation, can improve perforating efficiency.And pneumatic drill is from the punching of core below, and the residual sand in hole can drop automatically, to avoid residue to impact core quality.
Accompanying drawing explanation
Fig. 1 is that the utility model is played the main TV structure schematic diagram of vent device automatically for automobile engine cylinder-body basis core.
Fig. 2 is that the utility model is beaten the side cutaway view of vent device automatically for automobile engine cylinder-body basis core.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
Refer to shown in Fig. 1 and Fig. 2, the utility model discloses a kind ofly beats vent device automatically for automobile engine cylinder-body basis core, comprise housing 1, be covered in cover plate 2 on housing 1, be installed on a pair of positioner 3 on cover plate 2, be positioned at housing 1 lift cylinder 4, connect lift cylinder 4 laterally extending installing plate 5, be fixed on cover plate 2 inner sides and extend through the guide posts 6 of installing plate 5 downwards.When installing plate 5 moves up and down under the drive of lift cylinder 4, guide posts 6 can be to installing plate 5 location, lateral attitude so that installing plate 5 keeps stable motion.Described cover plate 2 is provided with opening 21, and described a pair of positioner 3 is located at respectively opening 21 both sides.Described positioner 3 comprises the rotary cylinder 31 being installed on cover plate 2 and is installed on the rotational positioning sheet 32 in rotary cylinder 31 rotating shafts, after basic core 8 is placed on cover plate 2, the rotational positioning sheet 32 of core 8 both sides, basis presses basic core 8 both sides and positions, and in the present embodiment, on described cover plate 2, be also provided with the locating piece 23 that is positioned at opening 21 both sides, described locating piece 23, between two positioners 3, coordinates further basic core 8 is positioned to carry out more accurately drilling operation in order to the locating slot with basic core 8 bottoms (not label).Installing plate 5 is provided with some pneumatic drills 7, and the drill bit 71 of described pneumatic drill 7 extends upward, and when installing plate 5 rises, drill bit 71 is through opening 21.
On described cover plate 2, be also provided with some gas blow pipes 22, described gas blow pipe 22 is positioned at the side of cover plate split shed 21 and the mouth of pipe of gas blow pipe 22 towards opening 21.When carrying out bore operation, because the drill bit 71 of pneumatic drill 7 is to be positioned at opening 21, gas blow pipe 22 just in time can blow to remove floating sand to boring point.
The utility model is realized the drilling operation to core by pneumatic drill is set, and installing plate positioner location core is set, use lift cylinder to regulate the height of pneumatic drill, whole apparatus structure is simple, be convenient to safeguard, and can once to a plurality of cores, carry out drilling operation, can improve perforating efficiency.And pneumatic drill is from the punching of core below, and the residual sand in hole can drop automatically, to avoid residue to impact core quality.
