[ detailed description of the invention ]

The invention is further described below with reference to the accompanying drawings:

as shown in the accompanying drawings, the utility model provides an interior concealed anchor clamps, including main part 1, slider 2, screw rod 3, bearing 4, spanner 5 and base 6, main part 1 is installed on base 6, mounting groove 7 has been seted up at main part 1 top, wear to be equipped with the screw rod 3 that the level was arranged in mounting groove 7, screw rod 3 is fixed in bearing 4, bearing 4 adorns the bottom in mounting groove 7, slider 2 is equipped with soon to screw rod 3's screw thread section, the internal thread of slider 2 is connected with the external screw thread cooperation of screw rod 3 screw thread section, 3 end connection of screw rod has spanner 5, screw rod 3 is rotatory under spanner 5's drive, and drive slider 2 removes along the horizontal direction, thereby can adjust the clamping interval at will.

As an embodiment of the utility model, all be provided with protruding little cylinder 8 on main part 1, the slider 2, little cylinder 8 on the main part 1 and the little cylinder 8 mutual disposition on the slider 2, and the interval drives slider 2 after 5 rotations by the spanner and removes and adjust, little cylinder 8 be used for with wait to clamp the drilling cooperation of part bottom and be connected. The small cylinder 8 on the main body 1 can be provided with one or two, the small cylinder 8 on the slide block 2 can be provided with two, and three or four small cylinders 8 are distributed in a triangular or rectangular shape, so that the clamping and positioning are more reliable.

As another embodiment of the utility model, all be provided with protruding cuboid 9 on main part 1, the slider 2, as shown in fig. 8, cuboid 9 on the main part 1 and the cuboid 9 on the slider 2 are arranged relatively, and the interval drives slider 2 after 5 rotations by the spanner and removes and adjust, and cuboid 9 is used for being connected with the fluting cooperation of waiting to clamp the part bottom. This cuboid 9 is the horizontal strip structure of placing, treats that the fluting on clamping part bottom both sides sets up to the rectangular channel with 9 looks adaptations of cuboid.

In the utility model, the main body 1 is designed into a column shape which is vertically arranged, and the cross section of the main body 1 can be round or square; the main body 1 can also be designed to be composed of an upper column and a lower column, the lower column is arranged on the base 6, a longitudinal bolt 10 is arranged at the top in the lower column, the upper column is screwed on the longitudinal bolt 10, and the height is adjusted through the longitudinal bolt 10.

Concealed anchor clamps can solve the anchor clamps appearance that exposed anchor clamps on the existing market exist when the clamping and be greater than the work piece and easily take place collision scheduling problem in the processing. The working principle of the concealed clamp is as follows: the bearing 4 is firstly arranged in the main body 1, the screw rod 3 penetrates through the main body 1 and is fixed in the bearing 4, then the sliding block 2 is aligned with the screw rod 3 and rotates clockwise by the wrench 5, the sliding block 2 can enter the main body 1, and then the clamping distance can be adjusted at will by rotating in the forward and reverse directions of the wrench 5. Wherein, main part 1 and 2 protruding columellas of total three (or four) in appearance of slider, when the clamping, only need to bore corresponding hole in the part bottom, overlap the hole on the columella, then with the firm compactness of spanner 5 positive and negative rotation adjustment clamping, so can realize built-in clamping, easy and simple to handle conveniently, nimble freely, avoided adding man-hour collision often taking place, improved work efficiency. In addition, three (or four) small cylinders on the appearances of the main body 1 and the sliding block 2 can be replaced by cuboids, and only two sides of the bottom of a part to be clamped are grooved, then the part to be clamped is correspondingly placed on the main body 1, the clamping distance can be adjusted by rotating the spanner 5 forwards and backwards, and thus the built-in clamping is realized.

The application range of the built-in clamp is wide, and the built-in clamp is particularly suitable for the electric spark machining of the mold industry. When the electrode material is used for electric spark machining in the mold industry, the electrode material can be clamped on the main body for modeling machining, the main body clamped with the electrode can be directly installed on the base for electric spark machining after the modeling machining is completed, the electrode does not need to be assembled and disassembled for many times, and the electrode does not need to be marked and classified, so that the working efficiency is greatly improved, errors caused by assembling and disassembling operations for many times are avoided, and the machining precision is greatly improved.

The present invention is not limited by the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and are all included in the protection scope of the present invention.
