Abstract
The utility model relates to a locking device for a door of a brazing furnace. The locking device comprises a clamping arm hinged on a furnace body, wherein one end of the clamping arm is connected with a cylinder hinged on the furnace body, while the other end of the camping arm is provided with a clamping head matched with the door of the brazing furnace. The clamping arm is automatically driven to rotate by the cylinder, so that door of the brazing furnace can be opened and closed; and the locking device is simple in structure, convenient to operate, safe and reliable, and excellent in locking performance and the locking device can be applied to operation in special environments such as the higher position of the furnace body with higher temperature or bigger size, and the like.
Description
Technical field
The utility model relates to soldering oven, specifically a kind of soldering oven fire door locking device.
Background technology
In commercial production, can use a large amount of closure containers, like the various bodies of heater in the vacuum brazing.Therefore part body of heater need design bigger fire door so that handling operation for it because of equipment such as needs loading and unloading large-scale components.When fire door is in closed state, because of arts demand must be locked fire door, when having pressure gap for some furnace pressures and atmospheric pressure or the airtight body of heater of needs particularly like this.
Existing fire door locking device generally adopts mechanical locking device, like the cramp frame locking device.This locking device need carry out the manual locking operation, and this operates very inconvenience under some particular surroundings, even can bring some potential safety hazards, operation like temperature on the higher or big type of furnace or the like.
Summary of the invention
The utility model provides a kind of soldering oven fire door locking device to the problems referred to above, and this locking device adopts operation automatically, convenient, safety.
Technical scheme according to the utility model: a kind of soldering oven fire door locking device, comprise the clamp arm that is hinged on the body of heater, an end of said clamp arm links to each other with cylinder on being hinged on said body of heater, and its other end is provided with the clamping head that matches with fire door.
The bolt that has been threaded on the said clamping head, the tail end of said bolt matches with said fire door.
Said bolt thread is connected with nut.
Said clamp arm is a V-arrangement, and its turning point is hinged on through bearing pin and clamps on the bearing, and said clamping bearing is fixed on the said body of heater.
Said cylinder is hinged on the cylinder block, and said cylinder block is fixed on the said body of heater.
The technique effect of the utility model is: the utility model drives clamp arm automatically through cylinder and rotates the switching that realizes fire door, and simple in structure, easy to operate, safe and reliable, locking property is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among Fig. 1, comprise cylinder block 1, cylinder 2, clamp bearing 3, bearing pin 4, plain cushion 5, clamp arm 6, bolt 7, nut 8, clamping head 9, fire door 10, body of heater 11 etc.
As shown in Figure 1, the utility model is a kind of soldering oven fire door locking device, comprises clamp arm 6 and cylinder 2.Cylinder 2 also can adopt oil cylinder to replace.
Clamp arm 6 is a V-arrangement, and its turning point is hinged on through bearing pin 4 and clamps on the bearing 3, clamps bearing 3 and is fixed on the body of heater 11.The plain cushion 5 of corrective action also has been installed on the bearing pin 4.
Cylinder 2 is hinged on the cylinder block 1, and cylinder block 1 is fixed on the body of heater 11.
One end of clamp arm 6 links to each other with the piston rod of cylinder 2 through bearing pin, and its other end is provided with the clamping head 9 that matches with fire door 10.
The bolt 7 that also has been threaded on the clamping head 9, the tail end of bolt 7 matches with fire door 10, plays regulating action.The nut 8 that also has been threaded on the bolt 7 plays clamping screw 7.
The operation principle of the utility model is: through to the pneumatic work of charging and discharging of cylinder 2, realize the elongation of cylinder 2 piston rods and shrink two states that cylinder 2 piston rods drive clamp arm 6 and realize clamping and the action of unclamping fire door 10.
The utility model drives clamp arm 6 automatically through cylinder 2 and rotates the switching that realizes fire door 10, and simple in structure, easy to operate, safe and reliable, locking property is good, and the operation that can be applicable on the higher or more large-scale body of heater high height of temperature waits some particular surroundings.
