[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A CNC double-head gantry milling machine includes a machining mechanism and a stripping mechanism. The machining mechanism includes a worktable, a hydraulic cylinder embedded in the top of the worktable, a lifting plate connected to the movable end of the hydraulic cylinder, and two milling machines vertically penetrating the lifting plate.

Then, when the hydraulic cylinder raises the lifting plate and pressure plate, once the pressure plate moves to the top of the material receiving platform, the material receiving platform and spring lose their restraint. The spring opens and then squeezes the material receiving platform to slide towards the stop bar. The impact force of the sudden sliding of the material receiving platform causes the processed workpiece to fall into the receiving box from the opening position, thereby achieving manual unloading and improving production efficiency.

[0010] In a preferred embodiment, the present invention can be further configured such that: two limiting plates are installed on the top of the workbench, and the two limiting plates are respectively attached to both sides of the lifting plate.

[0011] In a preferred embodiment, the present invention can be further configured such that: a guide rod is provided inside the spring, the guide rod movably passes through the baffle and is fixedly connected to the outer wall of the material holding platform.

[0012] In a preferred embodiment, the present invention can be further configured such that a stop bar is installed on the top of the workbench, and the stop bar is located outside the pressure plate.

[0013] In a preferred embodiment, the present invention can be further configured such that: two receiving boxes are movably inserted into the front side of the workbench, and the two receiving boxes are respectively located at the bottom of two openings.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, when the hydraulic cylinder lowers the lifting plate and pressure plate, it will squeeze the material receiving platform and spring. Then, when the hydraulic cylinder raises the lifting plate and pressure plate, once the pressure plate moves to the top of the material receiving platform, the material receiving platform and spring lose their restraint, the spring opens, and then squeezes the material receiving platform to slide towards the stop bar. Then, the impact force of the sudden sliding of the material receiving platform causes the processed workpiece to fall from the opening position into the receiving box, thereby achieving manual unloading and improving production efficiency.

[0016] 2. In this utility model, the workpiece to be processed is placed inside the square groove, and then the movable end of the hydraulic cylinder is controlled to retract.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes some embodiments of the CNC double-head gantry milling machine provided by this utility model with reference to the accompanying drawings.

[0031] Example 1:

[0032] Combination Figure 1-4 As shown, the CNC double-head gantry milling machine provided by this utility model includes a machining mechanism 100 and a stripping mechanism 200. The machining mechanism 100 includes a worktable 110, a hydraulic cylinder 120 embedded in the top of the worktable 110, a lifting plate 130 connected to the movable end of the hydraulic cylinder 120, and two milling machines 140 that vertically penetrate the lifting plate 130.

[0033] The unloading mechanism 200 includes a material receiving platform 210 attached to the top of the workbench 110, a spring 220 installed at one end of the material receiving platform 210, a baffle 230 connected between the workbench 110 and the spring 220, a pressure plate 240 connected to the lifting plate 130, an inclined surface 250 provided at the other end of the material receiving platform 210, and two openings 260 opened at the top of the material receiving platform 210. The bottom of the pressure plate 240 is attached to the inclined surface 250.

[0034] Furthermore, the two drilling and milling machines 140 are connected in series and are vertically symmetrical about the hydraulic cylinder 120. This structural design makes it convenient for operators to start the two drilling and milling machines 140.

[0035] Furthermore, the top of the material receiving platform 210 has two square grooves, which are located at the bottom of the two drilling and milling machines 140 respectively. Two openings 260 are located on one side of the two drilling and milling machines 140 respectively. The openings 260 are located inside the square grooves. The square grooves are provided to limit the workpiece to be processed.

[0036] Furthermore, a stop bar 500 is installed on the top of the workbench 110. The stop bar 500 is located outside the pressure plate 240. The stop bar 500 can prevent the material container 210, which is squeezed by the spring 220, from slipping off the workbench 110.

[0037] Furthermore, two receiving boxes 600 are movably inserted into the front side of the workbench 110. The two receiving boxes 600 are located at the bottom of the two openings 260 respectively. The receiving boxes 600 can be used to collect the processed workpieces in a unified manner.

[0038] Example 2:

[0039] Combination Figure 1 As shown, based on Embodiment 1, two limiting plates 300 are installed on the top of the workbench 110. The two limiting plates 300 are respectively attached to both sides of the lifting plate 130. Setting the limiting plates 300 can make the lifting plate 130 move straight up and down, so that the lifting plate 130 can rise and fall stably.

[0040] Example 3:

[0041] Combination Figure 1 and Figure 3 As shown, in the above embodiment, the spring 220 is provided with a guide rod 400 inside. The guide rod 400 movably passes through the baffle 230 and is fixedly connected to the outer wall of the material receiving platform 210. The guide rod 400 can guide the movement direction of the material receiving platform 210, so that the workpiece falling from the opening 260 can fall smoothly into the receiving box 600. In addition, the guide rod 400 can reduce the probability of the spring 220 deforming.

[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the workpiece to be processed is placed inside the square groove. Then, the movable end of the hydraulic cylinder 120 is controlled to retract, and then the lifting plate 130 lowers with two drilling and milling machines 140. Then, the workpiece in the square groove is processed. During this period, the pressure plate 240, which follows the descent of the lifting plate 130, squeezes the inclined surface 250, causing the material receiving platform 210 to squeeze the spring 220. Then, when the movable end of the hydraulic cylinder 120 extends, the lifting plate 130 raises with the pressure plate 240. When the pressure plate 240 reaches the top of the material receiving platform 210, the spring 220, which has lost pressure, suddenly opens and squeezes the material receiving platform 210 to slide towards the stop bar 500. Then, the impact force of the sudden sliding of the material receiving platform 210 causes the processed workpiece to fall from the opening 260 into the receiving box 600, thereby achieving manual unloading and improving production efficiency.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
