Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, the bolt assembly of the present embodiment comprises bolt 10 and pressing member 20.Bolt 10 has screw rod 11 and bolt head 12.Pressing member 20 has press part, and press part is arranged on the free end of screw rod 11.
The bolt assembly of application the present embodiment, owing to pressing member 20 being arranged on to the free end of bolt head 12, therefore, for example, in the time pressing workpiece (copper bar or band iron), the free-ended sharp-pointed position of screw rod 11 can contact with pressing member 20, and can not touch workpiece, like this, the free end of screw rod 11 and workpiece can not scratch workpiece in the time compressing.As the above analysis, the bolt assembly of the present embodiment can not scratch workpiece when with workpiece close contact.How bolt assembly specifically plays the effect of holding workpiece, will in compression bonding apparatus below, be described.
As depicted in figs. 1 and 2, in the present embodiment, be provided with receiving bore 13 on screw rod 11, pressing member 20 also has position-limited lever 21, and position-limited lever 21 is arranged in receiving bore 13.Position-limited lever 21 is arranged in receiving bore 13 and can realizes press part is arranged on the free end of screw rod 11, and said structure is simple, easy accessibility, and pressing member 20 and bolt 10 are without adopting linkage structure.
As shown in Figure 2, in the present embodiment, the axis of receiving bore 13 is parallel with the axis of screw rod 11, that is to say, receiving bore 13 is arranged on the free end of screw rod 11.Like this, facilitate the processing of receiving bore 13, in addition, press part can be served as in one end of position-limited lever 21.Certainly, receiving bore 13 can be arranged on the outer circumferential face of screw rod 11, and now, the axis of receiving bore 13 is vertical with the axis of screw rod 11.Receiving bore 13 is preferably blind hole.
As shown in Figure 1, in the present embodiment, press part, for to press platen 22, is fixed on one end of position-limited lever 21 by an end face of platen 22.Another end face of pressing platen 22 contacts with workpiece, therefore, has increased and the area of contact of workpiece, and workpiece is more stably fixed on compression bonding apparatus, on the other hand, can avoid scratching the protective film on workpiece by platen 22.
In the present embodiment, the degree of depth of receiving bore 13 is greater than the height of position-limited lever 21.Like this, in the time pressing workpiece, the free end of screw rod 11 can be supported on by platen 22, directly, to pressing platen 22 application of forces, has improved the structure stability of pressing member 20.In the time that the degree of depth of receiving bore 13 is less than or equal to the height of position-limited lever 21, can be to position-limited lever 21 application of forces at the bottom of the hole of receiving bore 13, easily cause position-limited lever 21 and wreck by the linkage structure of platen 22.
As shown in Figure 1, in the present embodiment, position-limited lever 21 is cylindrical bar.Cylindrical bar is easily processed, and easily stretches in receiving bore 13.In addition stressed more even in the radial direction of cylindrical bar.
As shown in Figure 2, in the present embodiment, the cross section of receiving bore 13 is circular.Circular port is easily processed, and facilitates position-limited lever 21 to stretch into.In addition, the hole wall of receiving bore 13 is more even in the application of force in the radial direction.
In the present embodiment, receiving bore 13 and position-limited lever 21 Spielpassung.Like this, when rotated, position-limited lever 21 can't rotate with screw rod 11 screw rod 11, has avoided being rotated in pressing workpiece by platen 22, causes and presses difficulty.
The application also provides a kind of compression bonding apparatus, and as shown in Figure 3, the compression bonding apparatus of the present embodiment comprises the bolt assembly of body 30 and above-described embodiment.Body 30 have with screw rod 11(as shown in Figure 1) the tapped hole (not shown) that coordinates and with press part corresponding forced section 31, between press part and forced section 31, form the clamping gap of holding workpiece.By mobile body 30, so that workpiece is positioned at clamping gap, then, by screwing screw rod 11, so that press part ground workpiece movable, and workpiece is fixed between press part and forced section 31 the most at last, like this, has realized the object of holding workpiece.As the above analysis, the compression bonding apparatus of the present embodiment can not scratch workpiece in the time of holding workpiece.
As shown in Figure 3, in the present embodiment, forced section 31 is stressed plate, and body 30 also has mounting plate 32 and joint 33, and stressed plate and mounting plate 32 be arranged in parallel, and tapped hole is arranged on mounting plate 32.Mounting plate 32 and stressed plate are convenient to be manufactured, simple in structure, in addition, easily on mounting plate 32, offers tapped hole, and the area of contact of stressed plate and workpiece is larger, cooperation more stable.Preferably, bolt assembly is two, the stability while having improved holding workpiece.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
