Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1 and 2, this embodiment is provided to solve the problem that the conventional stamp-engraving machine lacks a special fixture capable of rapidly clamping, and in consideration of a small clamping force required by the stamp-engraving machine.

The seal is anchor clamps for engraver that this embodiment provided, including being anchor clamps seat 1 and the holder of setting in anchor clamps seat 1 that the frame type set up, in this embodiment, anchor clamps seat 1 is formed through the bolt combination by four rectangular poles, in this embodiment, for convenient control, the mode of centre gripping carries out the centre gripping around adopting, for this reason, the holder that this embodiment provided is including preceding holder 2 and the back holder 3 that sets up around, preceding holder 2 is unanimous with back holder 3 structure, only both are the symmetry and set up.

The front clamping piece 2 and the rear clamping piece 3 provided by the embodiment both comprise a clamping piece body which is arranged in a cuboid shape and a clamping opening which is arranged on the clamping piece body, in order to meet the clamping of stamps with different specifications, in the embodiment, the clamping opening is arranged at one end of the front clamping piece 2, which is contacted with the rear clamping piece 3, wherein the clamping opening comprises a rectangular notch 4, a diamond notch 5 and a triangular notch 6, the thickness of the rectangular clamping opening in the clamping opening is about 1cm, when the square part is clamped, only the end face of the square part needs to be clamped, therefore, the thickness of the square part does not need to be too high, and the rhombus gaps 5 of the front clamping piece 2 and the rear clamping piece 3 are combined to form a rhombus arrangement, the triangular gaps 6 of the front clamping piece 2 and the rear clamping piece 3 form a square arrangement, and the rhombus gaps 5 and the square gaps can meet the clamping requirements of cylindrical pieces or irregular-shaped pieces.

In order to save cost, in this embodiment, the central lines of the rectangular notch 4, the rhombic notch 5 and the triangular notch 6 are overlapped, wherein the triangular notch 6 is sleeved in the rhombic notch 5, and since the thickness of the rhombic notch 5 is greater than that of the rectangular notch 4, two ends of the rhombic notch 5 are located in the rectangular notch 4, specifically, the length of the rectangular notch 4 is longest, the length of the rhombic notch is 5 times smaller, and the length of the triangular notch 6 is shortest.

Similarly, in order to satisfy the setting, preceding holder 2 and back holder 3 are run through from top to bottom to rectangle breach 4 and triangle-shaped breach 6, and the at least third of degree of depth of holder 2 and back holder 3 in the front of rhombus breach 5, if rhombus breach 5 runs through, just can't set up triangle-shaped breach 6, and the degree of depth of rhombus breach 5 can in order to satisfy the centre gripping treat the sculpture, because the clamping-force need not too big, for this reason, the degree of depth can be about 2 cm.

In order to realize quick clamping, two ends of the clamping piece body are provided with two-way screw rods 7, the two-way screw rods 7 penetrate through the front end and the rear end of the clamp seat 1, one end of each two-way screw rod 7 is provided with a control handle 71, and the front clamping piece 2 and the rear clamping piece 3 are respectively arranged at two ends of the two-way screw rods 7. Thus, the two-way screw rods 7 on two sides are rotated to realize the relative or opposite movement of the front clamping piece 2 and the rear clamping piece 3.

In the present embodiment, for more convenient control, a synchronizing wheel 72 is provided at one end of the bidirectional screw 7 away from the control handle 71, and a timing belt 73 is provided between the two synchronizing wheels 72. Therefore, relative or opposite movement can be realized by controlling one control handle 71, and the control handle 71 is a cylinder, so that the trouble of grabbing the bidirectional screw rod 7 by hands is avoided. In the present embodiment, an optical axis is provided outside the bidirectional screw 7 in order to match the timing belt 73 and to stabilize the operation thereof.

In order to reduce the structure of the head of the engraving machine and achieve the miniaturization setting as much as possible, in the embodiment, the bottom of the fixture seat 1 is provided with a sliding seat 8, a fixed seat 9 is arranged below the sliding seat 8, two sides of the fixed seat 9 are provided with rails 91, the bottom of the sliding seat 8 is provided with a sliding block 81 matched with the rails 91, the fixed seat 9 is provided with a driving motor 92, the power end of the driving motor 92 is connected with a lead screw 93, the lead screw 93 is rotatably arranged above the fixed seat 9, and the bottom of the sliding seat 8 is provided with a lead screw nut matched with the lead screw 93. Therefore, the clamp can realize the movement of the piece to be carved on the Z axis, so that the movement structure of the machine head is reduced, and the arrangement of miniaturization is more convenient.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
