[0028] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0029] Embodiment: As Figures 1 - 3 shown, the extrusion device for machining mechanical parts of the present utility model includes a support assembly 1, an extrusion assembly 2 and a U-shaped positioning plate 3 are installed at the upper end of the support assembly 1;

[0030] Among them, the support assembly 1 includes a processing table 101. A horizontally arranged driving groove 102 is opened at the upper end of the processing table 101. The extrusion assembly 2 is fixedly installed in the driving groove 102. The U-shaped positioning plate 3 is fixedly installed on the upper end surface of the processing table 101. The U-shaped positioning plate 3 is located on the right side of the driving groove 102. The left side of the U-shaped positioning plate 3 is provided with an opening;

[0031] The extrusion assembly 2 includes a motor 201. The motor 201 is fixedly installed on the left end surface inside the driving groove 102. The right end of the output shaft of the motor 201 is fixedly connected to a horizontally arranged threaded rod 203. The other end of the threaded rod 203 is rotatably connected to the right end surface inside the driving groove 102. A rectangular nut block 202 is threadedly sleeved on the threaded rod 203. An installation plate 205 is installed at the upper end of the rectangular nut block 202. The installation plate 205 is located above the driving groove 102. An extrusion positioning head 204 is installed at the right end of the installation plate 205. The extrusion positioning head 204 is located directly to the left of the U-shaped positioning plate 3.

[0032] A mechanical part can be placed inside the U-shaped positioning plate 3, and the right end of the mechanical part is closely abutted against the inner right end surface of the U-shaped positioning plate 3;

[0033] By starting the motor 201, the motor 201 can drive the threaded rod 203 to rotate when it works. The rotating threaded rod 203 can drive the rectangular nut block 202 to move to the right, and then can drive the installation plate 205 to move to the right. The moving right extrusion positioning head 204 can squeeze and fix the mechanical part inside the U-shaped positioning plate 3.

[0034] In this embodiment, as Figures 2 - 3 shown, the side end surface of the rectangular nut block 202 is slidably and fittingly attached to the inner wall of the driving groove 102 in the horizontal direction.

[0035] Through the above design, when the threaded rod 203 rotates, the rectangular nut block 202 can be stably driven in the horizontal direction.

[0036] A vertically arranged vertical rod 206 is fixedly installed at the middle position of the upper end surface of the rectangular nut block 202. The installation plate 205 is slidably sleeved on the vertical rod 206 in the vertical direction. Anti-slip lines are provided on the vertical rod 206. The installation plate 205 is detachably fixedly connected to the vertical rod 206 through a positioning set screw 207.

[0037] Loosen the positioning setscrew 207, then the height of the mounting plate 205 can be adjusted. After the adjustment is completed, tighten the positioning setscrew 207 to fix the mounting plate 205 on the vertical rod 206 again. Through the anti-slip pattern, the fixing effect between the positioning setscrew 207 and the vertical rod 206 can be improved, thereby improving the stability of the installation of the mounting plate 205.

[0038] As Figures 3 - 4 shown, an installation groove 209 is provided at the right end of the mounting plate 205, and the left end face of the extrusion positioning head 204 is in contact with the inner wall of the installation groove 209; a pressure sensor 208 is fixedly installed inside the mounting plate 205 and on the right side of the vertical rod 206. The sensing end at the right end of the pressure sensor 208 penetrates through the right end of the mounting plate 205 and extends to the inner side of the installation groove 209, and is fixedly connected to the left end of the extrusion positioning head 204. A first installation groove 103 and a second installation groove 104 are provided at the upper end of the processing table 101. A controller 4 is installed in the first installation groove 103, and an alarm 5 is installed in the second installation groove 104. The pressure sensor 208 is electrically connected to the controller 4, and the controller 4 is electrically connected to the alarm 5.

[0039] First, set a maximum value for the controller 4. When the extrusion positioning head 204 squeezes and positions the mechanical part, the extrusion positioning head 204 can transmit the extrusion force on the mechanical part to the pressure sensor 208. The pressure sensor 208 transmits the extrusion force information to the controller 4. The controller 4 is a SC200 general-purpose controller. The controller 4 converts the pressure information into data and compares it with the maximum value. When the data is equal to the maximum value, it means that the extrusion force of the extrusion positioning head 204 on the mechanical part has reached the maximum value. If it is further increased, it is easy to damage the mechanical part. At this time, the controller 4 will send an instruction to the alarm 5, and the alarm 5 can start to alarm. At this time, the staff needs to turn off the motor 201.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
