Utility model content
In order to solve problems of the prior art, the utility model provides a kind of pcb board fixture, simple in structure, easy to use, and is applicable to the fixing use of polytype pcb board, and the scope of application is wide, has a good application prospect.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of pcb board fixture, it is characterized in that: comprise base plate, described base plate is provided with a secondary symmetrically arranged clamping device, described clamping device comprises upperpush rod, be located at the lower supporting rod of upperpush rod below and be located at upperpush rod and lower supporting rod between spring, the two ends of described upperpush rod are provided with the first perforation, the two ends of described lower supporting rod are provided with second perforation corresponding with the first perforation, the two ends of described upperpush rod are equipped with bolt, the first perforation and the second perforation are run through in one end of described bolt, and be fixed on base plate by the second perforation, described upperpush rod is provided with the nut matching with bolt.
Aforesaid a kind of pcb board fixture, is characterized in that: described spring housing is located on bolt, and the length that described spring elongates extreme position is less than the height of bolt.
Aforesaid a kind of pcb board fixture, is characterized in that: described base plate is square, and described clamping device is evenly distributed on the two ends of base plate.
Aforesaid a kind of pcb board fixture, is characterized in that: four angles of described base plate are fillet design.
Aforesaid a kind of pcb board fixture, is characterized in that: on four angles of described base plate, be equipped with through hole.
Aforesaid a kind of pcb board fixture, is characterized in that: the below of described base plate is provided with rubber cushion.
The beneficial effects of the utility model are: a kind of pcb board fixture that the utility model provides, comprise base and the clamping device that is arranged on base two ends, by the two ends of the fixing pcb board of two clamping devices, thereby realize the fixing of pcb board, by the distance between upperpush rod and the lower supporting rod of adjusting clamping device, to meet the fixed demand of pcb board of different-thickness, owing to being provided with spring between upperpush rod and lower supporting rod, therefore be convenient to utilize the resilient support of spring to change the distance between upperpush rod and lower supporting rod, and spring housing is located on bolt, bolt-through upperpush rod and lower supporting rod, coordinate with nut by bolt, rotary nut changes the position of nut on bolt, be aided with the elastic force of spring simultaneously, realize the adjusting of upperpush rod position, in the time being rotated down nut, the elastic force that drives upperpush rod to overcome spring moves downward, arrival is suitable for behind the position of pcb board thickness, fix nut, and in the time need to discharging pcb board or increase the distance between upperpush rod and lower supporting rod, rotate up nut, simultaneously because upperpush rod is up withstood nut by the recovery of spring force, upperpush rod follows nut to move upward together, after arriving correct position, stop, in addition, because spring housing is located at bolt outside, the profile of bolt is fixed, and therefore, spring can arbitrarily not rock, and the plane at upperpush rod and lower supporting rod place, all the time perpendicular to base, avoids upperpush rod crooked, affects fixed effect.This pcb board fixture structure is simple, easy to use, and is applicable to the fixing use of polytype pcb board, and the scope of application is wide, has a good application prospect.
Brief description of the drawings
Fig. 1 is the structural representation of pcb board fixture of the present utility model.
Reference numeral implication is as follows:
1: base plate; 2: upperpush rod; 3: lower supporting rod; 4: spring; Perforation in 5: the first; Perforation in 6: the second; 7: bolt; 8: nut; 9: through hole.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of pcb board fixture, is characterized in that: comprise base plate 1, described base plate 1 is provided with a secondary symmetrically arranged clamping device, preferably base plate 1 is square, square backplane stability is high, and staff is a lot of and pcb board is a lot of when using, for fear of scratching staff or pcb board, four angles of base plate 1 are all designed to fillet, avoid the existence of wedge angle, also just avoided scratching the situation of staff or pcb board, be conducive to maintain carrying out smoothly of production; In the time using this fixture, sometimes need this fixture to be fixed on certain parts and to use again, therefore through hole 9 is all equipped with on four angles of base plate 1,, need to fix time, then be equipped with screw and nut and this fixture can be fixed on Anywhere, or be just placed on and on certain parts, do not need when fixing, because the below of base plate 1 is provided with rubber cushion, good antiskid effect, also can maintain basic the stablizing of base plate 1, prevents this fixture slip; In addition, described clamping device is evenly distributed on the two ends of base plate 1, clamping device is arranged on to the two ends of base plate 1, realizes the fixing of pcb board by the clamping device at two ends.
Detailed, described clamping device comprises upperpush rod 2, is located at the lower supporting rod 3 of upperpush rod 2 belows and is located at upperpush rod 2 spring 4 between lower supporting rod 3, lower supporting rod 3 is fixed on base plate 1, by regulating the distance between upperpush rod 2 and lower supporting rod 3, to meet the thickness requirement of pcb board of different-thickness, utilize the elastic force of spring 4 to realize the change of upperpush rod 2 and lower supporting rod 3 distances, the two ends of described upperpush rod 2 are provided with the first perforation 5, the two ends of described lower supporting rod 3 are provided with second perforation 6 corresponding with the first perforation 5, the two ends of described upperpush rod 2 are equipped with bolt 7, the first perforation 5 and the second perforation 6 are run through in one end of described bolt 7, and be fixed on base plate 1 by the second perforation 6, described upperpush rod 2 is provided with the nut 8 matching with bolt 7, spring 4 is set on bolt 7, described spring 4 elongates the height that the length of extreme position is less than bolt 7, bolt 7 can play with nut 8 and coordinate, regulate the effect of the distance between upperpush rod 2 and lower supporting rod 3, again due to the characteristic of himself vertical hard, avoid spring 4 run-off the straight in deformation process, ensure the effect of clamping pcb board.
When use, this fixture is fixed, the two ends of pcb board are placed between the upperpush rod 2 and lower supporting rod 3 of two clamping devices, be rotated down the nut 8 at upperpush rod 2 two ends simultaneously, nut 8 is pressed upperpush rod 2 straight down along the height of bolt 7, after pcb board is stepped up, hold-doun nut 8 is motionless, carry out the processing of pcb board, after machining, rotate up nut 8, upperpush rod 2 withstands nut 8 because the elastic force of spring 4 moves upward, move upward along with nut 8, then pcb board is taken out to the operation of carrying out next pcb board.
