Description
Technical Field
The invention relates to the technical field of machine tool part equipment, in particular to an adjustable clamp holder.
Background
In the process of workpiece processing, a saddle is often involved to move from a starting position to an end position in a fixed stroke; in the prior art, a sliding block is generally arranged at the bottom of a saddle and is matched with a sliding rail on a lathe bed, so that the sliding block can freely slide on the sliding rail; in order to facilitate the stopping of the saddle when the saddle slides to the corresponding position of the slide rail, a clamp is also arranged at the bottom of the saddle, the outer shape of the clamp is similar to that of a slide block, and the clamp can slide along the slide rail under the condition of no clamping.
For different processing workpieces and workpiece materials, a saddle needs better position fixing performance when working under the processing condition of some workpieces, namely, a clamp needs to have larger clamping area or clamping force on a sliding rail; in some workpiece processing situations, the saddle needs to have better motion flexibility, namely, the clamping device needs to have a smaller contact area with the sliding rail. The existing clamp holder has a certain length and a certain clamping area and contact area with the slide rail, so that the processing of the two conditions cannot be perfectly met at the same time, and the development of the clamp holder with adjustable clamping area and contact area is urgently needed.
Disclosure of Invention
The invention aims to provide an adjustable clamp holder, which solves the problem that the clamp holder in the prior art cannot adjust the clamping area and the contact area of the clamp holder and a slide rail.
The scheme is basically as follows:
an adjustable clamp, comprising:
a main holder to which a receiving part in a groove shape is connected;
the auxiliary holder is movably connected with the main holder and can enter the accommodating part;
the main holder and the auxiliary holder are respectively provided with a clamping groove, and the clamping grooves can be communicated with each other in a coaxial line.
Has the advantages that: therefore, the auxiliary clamp can be movably connected with different processing workpieces and moved out of the accommodating part, so that the auxiliary clamp can be combined with the main clamp, clamping grooves in the main clamp and the auxiliary clamp can be communicated coaxially, and the overall length of the clamp is increased. The length of the clamp holder is increased, the clamping area and the contact area are increased, the clamping force is higher than that of the rail, and the saddle position fixing performance is better. Meanwhile, the auxiliary clamp can move back to the containing part, the clamp and the slide rail only have the effect of the main clamp, the whole length of the clamp is reduced, the contact area is reduced, and the saddle is suitable for moving on the slide rail flexibly.
Further, the main holder is fixedly connected with a mounting plate, and the accommodating part is composed of the mounting plate and the main holder.
Thus, the accommodating part is arranged outside the main holder, and the size of the main holder is prevented from being increased compared with the case that the accommodating part is arranged in the main holder; the accommodating part is separated from the main holder, so that the maintenance of the main holder is facilitated; and meanwhile, the mounting plate is convenient for the main holder to be connected with the saddle.
Furthermore, the auxiliary holder and the main holder are movably connected in a sliding manner through a sliding structure.
Therefore, the auxiliary holder can slide out of the accommodating part linearly, and the volume of the accommodating part can be set to be minimum relative to the movable connection modes such as hinging, rotating and the like.
Further, sliding construction is including setting up the spout on the mounting panel, and vice holder's one end fixedly connected with is fixed with the slider with spout complex along length direction's extension board on the extension board.
The length direction is parallel to the movement direction of the main holder, when the main holder needs to be extended, the auxiliary holder can be moved out of the accommodating part through the sliding groove, and the extension plate ensures the stability of the sliding process.
Further, the spout includes horizontal spout and vertical spout, and the one end and the vertical spout intercommunication of horizontal spout, slider and vertical spout are more than two.
The extension plate can be left in the accommodating part, and the extension plate slides downwards along the vertical sliding groove to play a role of guiding the auxiliary holder to move downwards, so that the auxiliary holder does not need to be separated from the main holder when being butted with the main holder. Vertical spout is more than two for vice holder can tentatively fix a position.
Furthermore, hydraulic oil chambers are arranged in the main holder and the auxiliary holder and communicated with each other.
The hydraulic oil chamber is favorable for hydraulic clamping, and the oil chamber communication can ensure that the auxiliary clamping device and the main clamping device are synchronous in working.
Furthermore, a fixed block is fixed at the top of the main holder and can be matched and slidably connected with the clamping groove of the auxiliary holder. The stability of the auxiliary holder during sliding is improved, and the auxiliary holder can slide more smoothly.
Furthermore, a threaded hole is formed in the extension plate, a main mounting hole which can correspond to the threaded hole is formed in the mounting plate, and the threaded hole is connected with the main mounting hole through a connecting piece. The connecting piece can adopt a screw to fix the position of the auxiliary holder relative to the main holder, so that the position stability of the auxiliary holder and the main holder after combination is improved. Compared with other mounting modes, the screw mounting is simple in mounting and dismounting.
Furthermore, the fixed block is provided with a threaded blind hole, the auxiliary clamp is provided with an auxiliary mounting hole corresponding to the threaded blind hole, and the threaded blind hole is connected with the auxiliary mounting hole through a connecting piece. The connecting piece can also adopt a screw to fix another point through the auxiliary mounting hole and the main mounting hole, so that the fixation between the auxiliary holder and the main holder is improved.
Furthermore, a flexible hydraulic oil pipe is arranged between the main holder and the auxiliary holder, and the two hydraulic oil chambers are communicated through the hydraulic oil pipe. The communication mode of the two hydraulic oil chambers is set, so that the sealing structure on the communication structure is minimized, and the cost is reduced.
