The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The following detailed description of the embodiments of the invention is provided.
A clamping fixture is shown in figures 1 to 5 and comprises a base 1, a clamping seat 2, a clamping seat 3 and an auxiliary mounting seat 4 on the base, wherein the base is fixed on an equipment structure or a building foundation. A first driving mechanism 5 for driving the clamping seat to adjust the position and a second driving mechanism 6 for driving the clamping seat to adjust the position are arranged on the base;
a clamping head 7 is arranged on one side, facing the clamping seat, of the clamping seat, the clamping seat is detachably mounted on a transition seat 8, a second driving mechanism is hinged to the transition seat through a first hinge shaft 19, a connecting plate 9 is hinged to the transition seat, and the connecting plate is hinged to the transition seat through a second hinge shaft 20; the connecting plate is connected with the auxiliary mounting seat at one end different from the end hinged to the transition seat, the distance between the chuck and the clamping seat can be adjusted when the first driving mechanism drives the clamping seat to act, and the distance between the clamping seat and the chuck can be adjusted when the second driving mechanism drives the clamping seat to act.
The auxiliary mounting seat is fixed on the base through screws, a cylinder rod of the second driving cylinder penetrates through a through hole 16 of the auxiliary mounting seat, and one end, extending out of the auxiliary mounting seat, of the cylinder rod is hinged to the transition seat. The second driving mechanism and the hinged part between the transition seats are arranged in an axial vertical state, and the hinged part between the connecting plate and the auxiliary mounting seat and the hinged part between the connecting plate and the transition seats are arranged in an axial vertical state. By the structural design, the first driving mechanism and the second driving mechanism can be conveniently operated to act or operated to act simultaneously according to needs, so that the action operation of clamping and clamping the workpiece is more flexible and has small limitation.
It should be noted that, when the workpiece supporting seat is disposed on the base, the first driving mechanism and the second driving mechanism may be respectively adjusted to ensure that the workpiece is stably supported by the workpiece supporting seat, and the chuck and the clamping block on the clamping seat jointly clamp and fix the workpiece.
In an alternative embodiment, the clamping seat is hinged to the transition seat through a hinge, and the transition seat can limit the swing angle of the clamping seat. For example, the transition seat is provided with a mounting groove 10 along a vertical direction, a hinge 11 for connecting the clamping seat is arranged on a side wall of the mounting groove in a penetrating manner, the clamping seat comprises a connecting portion 12 and a clamping portion 13, the connecting portion is provided with a connecting hole 14 matched with the hinge, and a swing gap 15 is reserved between an inner side surface of the connecting portion and a groove bottom of the mounting groove.
Usually, the swing clearance is 1-5mm, and the clearance can ensure that the clamping seat has a certain swing deflection to adapt to the appearance of a workpiece, and can avoid overlarge swing amplitude. The clamping seat swings to adjust the position of the chuck, the position of the chuck can be adjusted in a self-adaptive mode for blank chucks with low surface precision, such as cast workpieces, the adaptability of the clamping jig is high, and the stability of the workpieces is guaranteed. It should be noted that, although the casting precision blank is poor, the size difference between the workpieces is not too large, and only a small size precision error exists, so that the clamping seat of the clamping jig is not required to be adjusted greatly. The articulated elements for connecting the clamping seats and the transition seats can adopt pin shafts with pull rings at the tail ends, so that the articulated elements can be very conveniently plugged and pulled out, and the clamping seats can be more conveniently installed or replaced.
By way of example, the first drive mechanism includes a first drive cylinder. Generally, the first driving cylinder adopts an electric cylinder, an air cylinder or a hydraulic cylinder. The second drive mechanism includes a second drive cylinder. Generally, the second driving cylinder adopts an electric cylinder, an air cylinder or a hydraulic cylinder.
In an alternative embodiment, in order to improve the stability when the second driving mechanism drives the clamping seat to act and ensure that the chuck of the clamping seat can be adjusted in position (close to or far away from the clamping seat in terms of distance) corresponding to the clamping seat all the time, the auxiliary mounting seat is provided with a connecting block 17 which is arranged on one side of the auxiliary mounting seat close to the clamping seat, namely, the connecting block is arranged on the auxiliary mounting seat at a position between the cylinder rod of the second driving cylinder and the clamping seat; the connecting plate is hinged with the connecting block. The connecting block can be effectively connected with the connecting plate, so that the problem that the rotating angle of the transition seat (when a hinge point between the second driving mechanism and the transition seat is used as an axis) is too large is solved, and the clamping effect of the clamping head is prevented from being influenced by the too large deflection angle of the clamping seat. In addition, an auxiliary supporting block 18 can be arranged on the clamping seat, and a V-shaped groove structure can be formed on the auxiliary supporting block so as to clamp and fix the workpiece. Certainly, the auxiliary supporting block can also be structurally designed as required, different workpieces matched with the auxiliary supporting block can be designed into different surface structure forms, and the matched auxiliary supporting block can be replaced according to the processing requirement.
The clamping device is reasonable in structural design, the first driving mechanism and the second driving mechanism can be respectively adjusted or a certain driving mechanism can be independently adjusted according to machining requirements, a workpiece is clamped and fixed between the clamping seat and the clamping seat, the workpiece is firmly fixed, and machining quality is guaranteed. Install the tight seat detachable of clamp of chuck and install on the transition seat, can be according to actual need, change the tight seat of clamp that the chuck specification is different or the structure is different, through outwards promoting the dress cassette and/or will press from both sides the inside pull-back of tight seat, can realize fixed to the centre gripping of work piece, strong adaptability, the commonality is good.
