The adjusting plate, the upper supporting frame and the ultrasonic welding assembly are adjusted in the Z-axis direction through the sliding type installation of the sliding type adjusting mechanism in the sliding groove, the adjustment of the welding distance between the welding head and the to-be-welded part is achieved, and the welding is completed by utilizing the ultrasonic welding principle during welding. Need not power drive, also need not vertical reciprocating motion alright accomplish welding work, satisfied the demand of sharp formula gauze mask machine in the synchronous completion welding broad ear area of work and weld forming gauze mask body.
But this type of gauze mask machine is automated production equipment, and the ear area welding part is by the lift stroke of 4 welding pressure heads of a cylinder simultaneous control in process of production, because there are inevitable machining error and assembly error between each part, leads to welding pressure head and oscillator steel mould clearance inconsistent for there is the phenomenon of welding infirm or overweld in 4 ear area welding points on the gauze mask lamellar body.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a gauze mask ear area welding set in adjustable clearance is provided, but the clearance automatic adjustment between during operation pressure head and the oscillator steel mould guarantees that the clearance is unanimous.
The utility model discloses the technical problem who adopts is:
the utility model provides a gauze mask ear area welding set in adjustable clearance, its includes the support body, fix the cylinder on the support body, install removal frame and the welding pressure head of setting on removing the frame on the cylinder piston rod remove to put up and be equipped with the through-hole, the upper end of welding pressure head is fixed with fastening screw after passing the through-hole, is equipped with the shaft shoulder on the welding pressure head, is equipped with the spring between shaft shoulder and removal frame.
Further, be equipped with linear bearing in the through-hole, the upper end and the linear bearing cooperation of welding pressure head, fastening screw and linear bearing's upper end cooperation is in order to realize the spacing of welding pressure head, the spring is located between the shaft shoulder and the linear bearing of welding pressure head.
Further, the movable frame comprises a movable plate, a sliding positioning rod fixed on the bottom surface of the movable plate and a fixing plate arranged at the bottom end of the sliding positioning rod, and the four welding pressure heads are evenly arranged on the fixing plate.
Further, the moving plate is connected with the frame body in a sliding mode.
The utility model discloses an actively the effect does: the utility model discloses an installation spring between welding pressure head and removal frame, the during operation, earlier can contract back with the welding pressure head of oscillator steel mould contact, through compressing tightly of spring adjust four welding pressure heads and oscillator steel mould clearance before, guarantee that every welding pressure head can all compress tightly with oscillator steel mould contact, make the ear area welding of 4 points even firm, avoid appearing the phenomenon that the ear area welding is not firm or cross the welding.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the attached figure 1, the utility model discloses a welding pressure head 1, spring 2, linear bearing 3, fastening screw 4, cylinder 5, removal frame, the gauze mask body 9, ear area 10, oscillator steel mould 11, support body 12 etc. part constitute.
The cylinder 5 is installed at the top of support body 12, installs the removal frame on the piston rod of cylinder 5, and welding pressure head 1 installs on removing the frame.
The movable frame comprises a movable plate, a sliding positioning rod 7 fixed on the bottom surface of the movable plate and a fixed plate 8 arranged at the bottom end of the sliding positioning rod 7, the movable plate is fixed with a cylinder piston rod, and the whole movable frame is driven by a cylinder to move so as to drive the welding pressure head to lift.
Be equipped with the through-hole on fixed plate 8, install linear bearing 3 in the through-hole, the upper end and the linear bearing 3 cooperation of welding pressure head 1 are equipped with fastening screw 4 at the top of welding pressure head 1, and when welding pressure head 1 was in the minimum position, fastening screw 4 overlap joint realized spacingly on linear bearing 3, were equipped with a shaft shoulder in the upper portion position of welding pressure head 1, were equipped with spring 2 between this shaft shoulder and linear bearing 3. There are 4 welding pressure heads 1, and four linear bearings 3 are correspondingly arranged on the fixing plate 8.
The below at welding pressure head 1 is equipped with the tray, and the welding front mask body 9 adorns in the tray, and its both sides are stretched out and are put on oscillator steel mould 11, and 4 ends of 2 individual ear areas 10 are put at the mask body splice, and the during operation cylinder pole stretches out, through the piston rod, slide positioning pole 7, fixed plate 8 drive 4 welding pressure head 1 downstream simultaneously, press respectively on 4 ends of ear area 10, realize the welding of the mask body 9 and ear area 10 through the 11 effects of oscillator steel mould.
