Detailed Description

The present invention will be further described in detail with reference to the following specific examples:

as shown in figures 1-3, the accessory equipment for taking and embedding the insert is used for detecting whether the insert is in place in real time in the processes of clamping and embedding the insert, and mainly comprises a clamping piece 1, a jacking piece 2 and a detecting piece 3.

The clamping piece 1 comprises a pair of parallel clamps 11 and a clamping jaw air cylinder 12 for driving the parallel clamps 11 to move relatively, a space 13 is formed between the parallel clamps 11, and a cavity 14 for clamping an insert is formed at the end part; the clamping member 1 may be an open-close type clamping jaw, and the embodiment takes the parallel clamp 11 as an example.

The jacking piece 2 is arranged in a telescopic alignment cavity 14, one end of the jacking piece is arranged in the interval 13, the other end of the jacking piece extends to the outer wall of the clamping jaw cylinder 12, and the jacking piece reciprocates along the direction vertical to the motion direction of the parallel clamp 11; the jacking part 2 is provided with a jacking needle 21 extending or retracting to one side of the cavity 14 and a telescopic sheet 22 extending or retracting to one side of the detection part 3, the jacking needle 21 and the telescopic sheet 22 are fixedly connected and are installed through a fixed seat 24, the fixed seat 24 is in an L-shaped structure, one end part of one side is fixedly connected with the outer wall of the clamping jaw air cylinder 12, and the other end part of the other side is positioned in the interval 13; the jacking needle 21 penetrates through the fixed seat 24, and the outer wall of the jacking needle is sleeved with a spring 23 and abuts against the fixed seat 24; when the insert is clamped in the cavity 14, the end part of the jacking needle 21 is abutted against the insert, the elasticity of the spring 23 is overcome, the insert is positioned at a contraction station, and meanwhile, in the process that the insert is clamped by the parallel clamp 11, the insert is required to be ensured not to be ejected out by overcoming the clamping force under the action of the elasticity of the spring 23; when the cavity 14 is not provided with the insert, the jacking needle 21 is reset under the elastic force of the spring 23, the end part of the jacking needle extends into the cavity 14, and the insert is ejected out to be in an extending working position.

Regarding the fixing seat 24, it should be noted that, since the positioning and guiding of the jacking needle 21 and the retractable sheet 22 are both attached to the fixing seat 24, the stability thereof is very important, in this embodiment, as shown in fig. 4, an abutting surface abutting against the side wall and the upper end surface of the clamping jaw cylinder 12 is provided on the vertical inner side end surface of the fixing seat 24, and the abutting surface is also L-shaped.

The detection piece 3 is matched with the jacking piece 2, and corresponding signals are output corresponding to the states that the jacking piece 2 is in a contraction station and an extension station; specifically, the detection part 3 adopts a combination of a magnetic reed switch 31 and a magnet 32, the magnetic reed switch 31 is fixedly connected with the outer wall of the clamping jaw cylinder 12 through a fixing block 33, and a telescopic cavity for the end part of the telescopic sheet 22 to enter is formed between the fixing block 33 and the outer wall of the clamping jaw cylinder 12; magnet 32 is mounted on the end of blade 22 and closes/opens reed switch 31 when moving toward/away from reed switch 31.

In this embodiment, the detection pieces 3 are provided with two sets, the pair of reed switches 31 are installed in a rotational symmetry manner, the pair of magnets 32 respectively correspond to the set of reed switches 31, and when the jacking piece 2 is in a contraction station state and an extension station state, the closing of the corresponding reed switches 31 is respectively realized, so that the detection pieces are used for detecting signals whether the picking piece is in place or not and signals whether the embedded piece is in place or not.

Regarding the operating principle of the reed switch 31: two magnetizable reeds are sealed in a glass tube, the distance between the two reeds is only about a few microns, the glass tube is filled with high-purity inert gas, and the two reeds are not contacted when not in operation; when an external magnetic field is applied, the magnetic field enables the end positions of the two reeds to generate different polarities, and the two reeds with different polarities attract each other and are closed.

The working principle of the invention is as follows:

when taking the piece: when the inserts are fed in place, the pair of parallel clamps 11 clamp the inserts, meanwhile, the jacking needle 21 is pressed in by overcoming the elastic force of the spring 23 under the action of the inserts entering the cavity 14, the telescopic sheet 22 moves along with the inserts, the magnet 32 on the corresponding side is close to the end parts of the pair of reeds in the magnetic reed switch 31, the magnetic reed switch 31 is closed (at the moment, the magnetic reed switch 31 on the other side is in an open state), and then a signal of successful clamping is received; if the clamping is unsuccessful, the jacking needle 21 is not pressed in, the magnetic reed switch 31 on the corresponding side cannot sense the magnet 32 approaching signal and cannot be closed, the workpiece taking failure is indicated, and the alarm is stopped.

When embedding the parts: when the insert is embedded into the mold, the pair of parallel clamps 11 is opened, the jacking needle 21 is reset under the elastic force of the spring 23 and sends out the insert, the telescopic sheet 22 also moves along with the insert, and the magnet 32 on the other side is close to the corresponding magnetic reed switch 31 to close the magnetic reed switch 31 (the corresponding closed magnetic reed switch 31 is disconnected during workpiece taking), so that a signal of successful workpiece embedding is received; if the embedded part is unsuccessful, the jacking needle 21 is not ejected or is not ejected in place, the corresponding magnetic reed switch 31 cannot sense the approaching signal of the magnet 32 and cannot be closed, the embedded part is failed, and the alarm is stopped.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore intended that the present embodiments be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
