Description

The pneumatic swelling fixture of motor case quick change
Technical field
The utility model is related to a kind of fixtures, specifically the motor machine when processing motor case, for being fixed The pneumatic swelling fixture of shell quick change.
Background technology
Currently, the motor case swelling fixture used in machining industry includes bottom plate, cone is evenly equipped on bottom plate The support base of shape, that smaller one end of support base diameter upward, and are cased with expansion tube thereon, and the upper end of expansion tube is provided with end Lid, the surrounding of end cap are connected with the madial wall of expansion tube upper end, there is spacing, support base and end between end cap and the upper surface of support base There is adjusting screw between lid.In use, casing embryo material to be first set to the outside of expansion tube successively;Then, manual locking is adjusted successively Screw makes expansion tube extrusion expansion between support base and blank, to fix blank.After the processing is completed, loose manually successively Adjusting screw is opened, casing blank is removed.This fixture needs manual locking, unclamps adjusting when fixing and removing embryo material Screw, the degree of automation is low, and working efficiency is relatively low.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of pneumatic swelling fixture of motor case quick change, the fixtures It is not necessary that clamping screw is manually operated, the degree of automation and working efficiency are higher.
To solve the above problems, providing following technical scheme:
The pneumatic swelling fixture of motor case quick change of the utility model includes bottom plate, and cone shape is evenly equipped on bottom plate Support base, that smaller one end of support base diameter upward, and are cased with expansion tube thereon, and the upper end of expansion tube is provided with end cap, end The surrounding of lid is connected with the madial wall of expansion tube upper end, has spacing between end cap and the upper surface of support base.Its main feature is that the branch There is the first centre bore on support seat, there is pull rod in the first centre bore, in sliding shape cooperation, the end cap between pull rod and the first centre bore It is in be linked between pull rod.The pneumatic mechanism of driving pull rod sliding is useful on the bottom plate.
Wherein, there is the second centre bore on the end cap, short connecting rod, the both ends of short connecting rod have been arranged concentrically in the second centre bore It is stretched out respectively from the both sides of end cap, the upper end of short connecting rod is provided with round clamp, and the lower end of short connecting rod connects with the pull rod in concentric It connects, the outer diameter of pull rod and round clamp is all higher than the aperture of the second centre bore, and the outer diameter of short connecting rod is less than the aperture of the second centre bore.
The bottom of the bottom plate is provided with cushion block, has abdicating through hole on the bottom plate below first centre bore, described Pneumatic mechanism includes the cylinder being located at below each abdicating through hole, and the piston rod of cylinder both passes through corresponding abdicating through hole and pull rod phase Even.
Above scheme is taken, is had the following advantages:
Due to there is the first centre bore on the support base of the pneumatic swelling fixture of the motor case quick change of the utility model, first There is pull rod in centre bore, is in be linked between the end cap and pull rod in sliding shape cooperation between pull rod and the first centre bore, bottom plate On be useful for driving pull rod sliding pneumatic mechanism.In use, control pneumatic mechanism pulls pull rod to drive expansion tube and support base Extrusion expansion loosens, to realize the swelling of motor case or loosen, compared with background technology turns adjusting screw manually, greatly It is big to improve work efficiency and the degree of automation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the pneumatic swelling fixture of motor case quick change of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the motor case 12 of the utility model includes bottom plate 1, bottom plate with the pneumatic swelling fixture of quick change The support base 8 of cone shape is evenly equipped on 1, that smaller one end of 8 diameter of support base upward, and is cased with expansion tube 5 thereon, expansion The upper end of pipe 5 is provided with end cap 4, and the surrounding of end cap 4 is connected with the madial wall of 5 upper end of expansion tube, and end cap 4 is upper with support base 8 There is spacing between end face.There is the first centre bore 7 on the support base 8, there is pull rod 6, pull rod 6 and the first center in the first centre bore 7 It is in be linked between the end cap 4 and pull rod 6 in sliding shape cooperation between hole 7.Driving pull rod 6 is useful on the bottom plate 1 to slide Pneumatic mechanism.
There is the second centre bore on the end cap 4, short connecting rod 3, the both ends point of short connecting rod 3 have been arranged concentrically in the second centre bore It is not stretched out from the both sides of end cap 4, the upper end of short connecting rod 3 is provided with round clamp 2, and the lower end of short connecting rod 3 is with the pull rod 6 in concentric The outer diameter of connection, pull rod 6 and round clamp 2 is all higher than the aperture of the second centre bore, and the outer diameter of short connecting rod 3 is less than the second centre bore Aperture.
The bottom of the bottom plate 1 is provided with cushion block 9, has abdicating through hole on the bottom plate 1 of first centre bore, 7 lower section 11, the pneumatic mechanism includes the cylinder 10 for being located at 11 lower section of each abdicating through hole, and the piston rod of cylinder 10, which both passes through correspondence, to be allowed Position through-hole 11 is connected with pull rod 6.
In use, 12 embryo material of casing to be first set to the outside of expansion tube 5 successively;Then, all cylinders 10 are controlled while being drawn Dynamic pull rod 6 drives expansion tube 5 and 8 extrusion expansion of support base, to fix blank.After the processing is completed, all cylinders are controlled 10 pull pull rod 6 that expansion tube 5 is driven to loosen with support base 8 simultaneously, remove 12 blank of casing.
