[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] During the processing of metal castings, drilling is a common process in metal casting processing. When drilling holes in metal castings through a punching device, since each metal casting has different requirements for the type of holes, different types of punching devices are required for drilling holes in castings with different requirements. When replacing, the corresponding type of punching device cannot be installed quickly, which makes the replacement efficiency slow, thereby affecting the processing efficiency. Therefore, a metal casting punching machine is proposed to solve the above problem. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a metal casting punching machine, comprising a frame, on which a supporting mechanism, a hole-opening mechanism and a temporary storage mechanism are fixed;

[0006] The support mechanism includes a mounting plate capable of linear motion and rotational motion on the X-axis and rotational motion on the Y-axis;

The output shaft of the Y-axis rotary motor is fixed to a mounting plate through a commutator, and the mounting plate is parallel to the support plate.

[0010] Furthermore, four sensors are fixed on the top surface of the support plate and are equidistantly distributed in a circle, and a corresponding sensing sheet is fixed on one side of the mounting plate close to the support plate.

[0011] Furthermore, a Y-axis linear module is fixed on the frame, a Z-axis rotary motor driven by the Y-axis linear module to perform linear motion is fixed to the output end of the Y-axis linear module, a Z-axis linear module is fixed to the output shaft of the Z-axis rotary motor, and the punch is installed at the output end of the Z-axis linear module.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 A metal casting punching machine in this embodiment includes a frame 1, on which a supporting mechanism 2, a hole-punching mechanism 3 and a temporary storage mechanism 4 are fixed. The workpiece is supported by the supporting mechanism 2 and then punched by the hole-punching mechanism 3. The temporary storage mechanism 4 can realize the automatic change of the hole-punching mechanism 3 to adapt to different punching requirements.

[0027] like Figure 2As shown, the support mechanism 2 includes an X-axis linear module 201 fixed on the frame 1, the output shaft of the X-axis linear module 201 is fixed with a support frame 202 driven by it to perform forward and backward linear motion, a pair of fixed frames 203 are fixed on the support frame 202, an X-axis rotary motor 204 is fixed on one side of the fixed frame 203, the output shaft of the X-axis rotary motor 204 is fixed with a support plate 205 which is rotatably arranged on the other side of the fixed frame 203 through a bearing, a Y-axis rotary motor 206 is fixed to the bottom surface of the support plate 205, and the output shaft of the Y-axis rotary motor 206 is fixed with a mounting plate 207 parallel to the support plate 205 through a commutator.

[0028] There are several mounting holes on the mounting disk 207, which can be used for different types of workpiece clamping fixtures to be installed on the mounting disk 207, and can be flexibly adjusted according to appropriate working scenarios. In addition, the X-axis linear module 201 can drive the mounting disk 207 to move linearly back and forth, the X-axis rotary motor 204 can drive the mounting disk 207 to rotate in the X-axis direction, and the Y-axis rotary motor 206 can drive the mounting disk 207 to rotate in the Y-axis direction, thereby driving the workpiece to change at multiple angles, which can be flexibly adjusted according to processing requirements.

[0029] In addition, four sensors 208 equidistantly distributed in a circle are fixed to the top surface of the support plate 205 , and a corresponding sensing sheet 209 is fixed to the side of the mounting plate 207 close to the support plate 205 . The rotation angle of the mounting plate 207 can be determined through the recognition and induction of the sensors 208 and the sensing sheets 209 .

[0030] like Figure 3-5 As shown, the hole opening mechanism 3 includes a Y-axis linear module 301 fixed on the frame 1, the output end of the Y-axis linear module 301 is fixed with a Z-axis rotary motor 302 driven by the Y-axis linear module 301 to perform linear motion, the output shaft of the Z-axis rotary motor 302 is fixed with a Z-axis linear module 303, and the output end of the Z-axis linear module 303 is installed with a punch 304.

[0031] The Y-axis linear module 301 and the Z-axis linear module 303 can change the position of the punch 304 on the Y-axis and the Z-axis, while the Z-axis rotary motor 302 can control the punching angle of the punch 304 and can be flexibly adjusted according to the workpiece being processed.

[0032] In order to enhance the stability of the punch 304 after the angle is changed, a mounting bracket 305 is fixed to the output end of the Y-axis linear module 301, a limiting bracket 306 is fixed to the top of the mounting bracket 305, a positioning cylinder 307 is fixed to the end of the limiting bracket 306, and a positioning rod 308 extending from the other end of the limiting bracket 306 is fixed to the output shaft of the positioning cylinder 307, and the mounting plate on the back of the Z-axis linear module 303 has an annular positioning groove that matches the positioning rod 308.

[0033] After the Z-axis rotary motor 302 drives the punch 304 to rotate to a suitable angle, the positioning cylinder 307 is ejected, and the positioning rod 308 moves into the annular positioning groove and abuts against the Z-axis linear module 303, so that the punch 304 has stronger stability after changing the angle.

[0034] In order to further improve the flexibility during processing, a male connector 309 is fixed to the output end of the Z-axis linear module 303, and a female connector 310 that is quickly connected to the male connector 309 is fixed to the punch 304.

[0035] The female connector 310 on the punch 304 is suspended on the cross temporary storage plate 403 through the placement slot 404, and the driving motor 402 can change the direction of the cross temporary storage plate 403 to facilitate rapid docking with the male connector 309 on the hole opening mechanism 3.

[0036] When it is necessary to replace the punch 304 on the hole opening mechanism 3, first remove the existing punch 304 on the hole opening mechanism 3, and then use the Y-axis linear module 301 to drive the male connector 309 to move to the top of the female connector 310 corresponding to the punch 304 on the cross temporary storage plate 403, and the Z-axis linear module 303 drives the male connector 309 to move downward and quickly assemble with the female connector 310, and then take the punch 304 out from the opening of the corresponding placement slot 404 to complete the model change operation.

[0037] By adopting the above-mentioned metal casting punching machine, the punching machine 304 model can be flexibly changed according to different working scenes, and the flexibility of use is better. The specific operation method is as follows:

[0038] Install the workpiece clamping fixture on the mounting plate 207, and then clamp the workpiece on the fixture, and then use the X-axis linear module 201 to drive the workpiece to move linearly back and forth, the X-axis rotary motor 204 drives the workpiece to rotate in the X-axis direction, and the Y-axis rotary motor 206 drives the workpiece to rotate in the Y-axis direction. After adjusting the processing orientation of the workpiece, change the orientation of the punching machine 304 on the Y-axis and Z-axis through the Y-axis linear module 301 and the Z-axis linear module 303, and the Z-axis rotary motor 302 controls the punching angle of the punching machine 304. After the orientation of the punching machine 304 is adjusted, the punching machine 304 can be used to perform punching operations on the workpiece.
