DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0030] Please refer to Figures 1 to 3 The present application provides a technical solution: a calibration discharge tool jig based on a pneumatic valve for quickly connecting and fixing an electrode, comprising a connecting seat 1, a connecting assembly 200 is installed on the top of the connecting seat 1, and a positioning assembly 300 is installed on the bottom of the connecting seat 1; through the cooperation between the connecting assembly 200 on the top of the connecting seat 1 and the positioning assembly 300 on the bottom, the adaptability of electrode positioning can be improved through the power output positioning structure based on the pneumatic valve, so that most electrodes of different sizes and even different shapes can be effectively positioned, thereby facilitating the normal operation of calibration discharge work, and improving the adaptability of the tool jig to different electrodes, so that the practicality of the tool jig is effectively improved.

[0031] The positioning assembly 300 in the embodiment is a structure for facilitating positioning of electrodes of different sizes.

[0032] As Figure 1 , Figure 2 and Figure 3As shown, the positioning assembly 300 comprises a pneumatic valve body 301 at the bottom of the connecting seat 1, a circular truncated cone block 302 fixedly installed on the output shaft of the pneumatic valve body 301, four fixed rods 303 fixedly installed at the bottom of the pneumatic valve body 301, a positioning cylinder 304 fixedly installed between the four fixed rods 303 near the circular truncated cone block 302, an electrode body 305 inserted into the inner side of the positioning cylinder 304, four push blocks 306 at the top of the positioning cylinder 304, four movable holes 307 opened at the top of the positioning cylinder 304, a rotating rod 308 rotatably connected to the inner side of the movable hole 307 through a bearing, a rotating plate 309 fixedly installed on the outer side of the rotating rod 308, a connecting sheet 310 hingedly connected to the rotating plate 309 near the electrode body 305 through a pin shaft, a pressing plate 311 fixedly installed on the connecting sheet 310 near the electrode body 305, and a gasket 312 adhesively installed on the pressing plate 311 near the electrode body 305.

[0033] It should be noted that the diameter of the bottom of the circular truncated cone block 302 is smaller than the diameter of the top, and the outer side of the circular truncated cone block 302 can be attached to the side of the push block 306 near the circular truncated cone block 302. The corners of the push block 306 are arc-shaped, so that the circular truncated cone block 302 can drive the push block 306 to move during the downward movement driven by the pneumatic valve body 301. The movable hole 307 can allow the corresponding rotating plate 309 to normally rotate, so that the rotating plate 309 can normally move in the inner side of the movable hole 307.

[0034] In addition, the bottom of the positioning cylinder 304 is provided with an opening, so that the electrode body 305 can be normally placed in the inner side of the positioning cylinder 304. The top of the rotating plate 309 is fixedly connected to the bottom of the corresponding push block 306, so that the push block 306 can drive the corresponding rotating plate 309 to rotate when it is driven to move. The pressing plate 311 is located in the inner side of the positioning cylinder 304, so that the pressing plate 311 can extrude and limit the outer side of the electrode body 305 when it is driven to move by the rotating plate 309.

[0035] At the same time, the angle between the top of the pressing plate 311 and the side of the corresponding rotating plate 309 near the electrode body 305 is at most forty-five degrees, so that the side of the rotating plate 309 near the electrode body 305 can limit the pressing plate 311 to a certain extent. Therefore, when the electrode body 305 is not inserted into the inner side of the positioning cylinder 304, the natural placement angle of the pressing plate 311 will not be too large, which is convenient for the entry of the electrode body 305 and the extrusion and positioning of the pressing plate 311. The surface of the gasket 312 is irregularly wavy, and the gasket 312 is a hard and wear-resistant rubber pad, which can achieve good anti-skid positioning effect and can meet the long-term use requirement.

[0036] The connecting assembly 200 in the embodiment is a structure for connecting a jig.

[0037] As Figure 1As shown, the connecting assembly 200 comprises a connecting groove 201 opened at the top of the connecting base 1, a jig body 202 inserted into the inner side of the connecting groove 201, a plurality of first bolts 203 penetrating the outer side of the connecting base 1, a connecting plate 204 abutting the bottom of the connecting base 1, and a plurality of second bolts 205 penetrating the bottom of the connecting plate 204.

[0038] It should be noted that the outer side of the jig body 202 is provided with a plurality of first threaded grooves for threadedly connecting the plurality of first bolts 203, and the bottom of the connecting base 1 is provided with a plurality of second threaded grooves for threadedly connecting the plurality of second bolts 205, so that the jig body 202 can be fixed to the inner side of the connecting groove 201 through the cooperation between the first bolts 203 and the first threaded grooves, and the connecting plate 204 can be fixed to the bottom of the connecting base 1 through the cooperation between the second bolts 205 and the second threaded grooves.

[0039] It should be further noted that the jig body 202 can be fixed to the outer side of the discharge machine through bolts or other connecting members. The discharge machine is a machining method for machining materials by using the electric corrosion phenomenon of pulse spark discharge between two poles (tool electrode and workpiece electrode) in a certain medium, so as to make the size, shape and surface quality of the part meet the predetermined requirements. It can be used for electrode calibration discharge work. The pneumatic valve body 301 is fixed to the bottom of the connecting plate 204, so that the pneumatic valve body 301 can be connected and fixed to the bottom of the connecting base 1 through the connecting plate 204.

[0040] The working principle of the above embodiment is as follows:

[0041] When it is necessary to position the electrode for calibration discharge work, the electrode body 305 is inserted into the inner side of the positioning cylinder 304, the pneumatic valve body 301 is started, the circular truncated cone block 302 is driven to move by the output shaft, the outer side of the push block 306 is pushed under the pushing action of the outer side inclined surface of the circular truncated cone block 302, the rotating plate 309 is rotated on the outer side of the corresponding rotating rod 308, the pressing plate 311 clamps and limits the electrode body 305 through the gasket 312, and then the jig body 202 and the electrode body 305 are fixed on the discharge machine together, so as to facilitate the normal calibration discharge work.

[0042] Compared with the prior art, the fast connection and fixed electrode calibration discharge tooling jig based on the pneumatic valve can improve the adaptability of electrode positioning through the power output positioning structure based on the pneumatic valve, so that most electrodes of different sizes or even different shapes can be effectively positioned, thereby facilitating the normal operation of the calibration discharge work, improving the adaptability of the tooling jig to different electrodes, effectively improving the practicality of the tooling jig, and solving the problem of low adaptability of the existing tooling jig to different size electrodes in actual use.

[0043] The electrical components in the text are electrically connected with the main control unit and the power supply. The provision of the power supply is a common knowledge in the art. The main control unit can be a computer or other conventional known device that can be controlled. Through simple programming by those skilled in the art, it can be realized. And it is an existing public power connection technology, which is not described in detail in the text.
