DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-Figure 6A CNC machine tool transmission device includes a machine body 1, and load-bearing legs 2 are fixedly connected to the front and rear ends of the machine body 1. A reinforcing rib 4 is fixedly connected between the two load-bearing legs 2 on the same side of the front and rear. The reinforcing rib 4 can not only strengthen the two load-bearing legs 2 on the same side, but also provide a guiding and limiting function for the pusher 14, and a feeding channel 3 for conveying materials is opened at the upper end of the machine body 1.

[0027] The machine body 1 is fixedly provided with a pre-processing mechanism for conveying a single material to the feeding channel 3. Figure 5 With attached Figure 6 The pretreatment mechanism includes a three-way pipe 17 fixedly arranged on the machine body 1 and corresponding to the feeding channel 3, a second motor 18 is fixedly installed at the bottom of the three-way pipe 17, and a driving gear 19 is keyed to the output end of the second motor 18, two driven racks 20 meshing with the driving gear 19 are slidably installed at the bottom of the three-way pipe 17, a clamping plate 21 for clamping and fixing the raw material is slidably sleeved on the upper end of the three-way pipe 17, and a synchronous frame 22 is fixedly connected between the driven rack 20 and the clamping plate 21, and the second motor 18 is fixedly installed with a second motor 18. Under the driving action, the two clamping plates 21 move toward each other to clamp and fix the raw materials that move downward as a whole through the three-way pipe 17. A driving cylinder 23 is fixedly installed on the three-way pipe 17, and a cutting piece 24 for cutting the raw materials from the middle opening of the three-way pipe 17 is fixedly installed on the output end of the driving cylinder 23. When the raw materials are balanced and fixed in the three-way pipe 17 as a whole, the cutting piece 24 extending into the three-way pipe 17 is used to quantitatively cut the raw materials, thereby forming individual materials that move toward the feeding channel 3.

[0028] At least two materials are placed in a straight line and equidistantly on the feeding channel 3 , and move forward horizontally under the pushing and pressing action of the pusher 14 .

[0029] A first motor 5 is fixedly arranged on the load-bearing leg 2 at the rear side, and the machine body 1 is provided with a feeding mechanism for step-by-step conveying of materials through the first motor 5. The feeding mechanism includes a first rotating shaft 6 rotatably mounted on the rear load-bearing leg 2 and fixedly connected to the output end of the first motor 5, and a second rotating shaft 7 is rotatably mounted on the front load-bearing leg 2, and a first connecting rod 8 and a second connecting rod 9 are rotatably connected to the first rotating shaft 6 and the second rotating shaft 7 respectively, and a traction member 10 is movably connected between the first connecting rod 8 and the second connecting rod 9. It should be noted that because the second connecting rod 9 has a guiding limit to the traction member 10, The traction member 10 is in the same position as the first connecting rod 8, so that the traction member 10 can move reciprocatingly in the circumferential direction under the traction action of the first connecting rod 8. A guide long hole 11 is opened on the reinforcing rib 4, and the guide long hole 11 is opened vertically. A guide block 12 is slidably sleeved in the guide long hole 11, and a telescopic support rod 13 is slidably sleeved in the guide block 12. A pusher 14 is fixedly connected to the telescopic support rod 13, which is movably pulled by the traction member 10 and is used to push the material forward. Under the traction action of the pusher 14, the telescopic support rod 13 is horizontally extended and retracted in the guide block 12, and at the same time, the guide block 12 is driven to move up and down in the vertical direction of the guide long hole 11.

[0030] Please refer to the instruction manual for details Figure 3 The machine body 1 is horizontally arranged, and the reinforcing ribs 4 are symmetrically arranged on the front and rear sides of the machine body 1 to provide active support for the pusher 14 from the front and rear sides.

[0031] The first connecting rod 8 and the second connecting rod 9 are eccentrically mounted on the first rotating shaft 6 and the second rotating shaft 7 respectively. The first connecting rod 8 drives the traction member 10 to move under the traction action, while the second connecting rod 9 limits the movement range of the traction member 10.

[0032] Please refer to the instruction manual for details Figure 4 The traction member 10 is composed of a horizontal rod 1001 and a vertical rod 1002. The two ends of the horizontal rod 1001 are rotatably connected to the first connecting rod 8 and the second connecting rod 9 respectively, and the lower end of the pusher 14 is integrally connected with a connecting end 15 connected to the pin shaft of the vertical rod 1002. Because the second connecting rod 9 is limited and pulled, the traction member 10 moves back and forth under the traction action of the first connecting rod 8.

[0033] The pusher 14 is fixedly connected with at least three push plates 16 corresponding to the materials, and the three push plates 16 are equidistantly distributed in a straight line. The number of push plates 16 can be set according to the length of the machine body 1 and the amount of materials, so as to facilitate the transportation of the corresponding amount of materials.

[0034] The lower opening of the three-way pipe 17 is connected to one end of the feeding channel 3, and the cut single material moves to the feeding channel 3 through the lower non-opening of the three-way pipe 17, and the two driven racks 20 are centrally symmetrically arranged at both sides of the driving gear 19.

[0035] It should be noted that the specific models and specifications of the motor and cylinder need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0036] The functional principle of the utility model can be explained through the following operation modes:

[0037] The raw material is put into the three-way pipe 17 as a whole, and moves vertically downward under the action of gravity;

[0038] The second motor 18 is controlled to be turned on, and the output end of the second motor 18 drives the driving gear 19 to rotate, thereby driving the two driven racks 20 to move toward each other, and the driven racks 20 drive the two clamping plates 21 to clamp and fix the raw material through the synchronous frame 22;

[0039] The driving cylinder 23 is controlled to open, and the output end of the contracted driving cylinder 23 quantitatively cuts the raw material through the cutting piece 24, so that the cut single material falls and moves to the feeding channel 3;

[0040] The first motor 5 is controlled to be turned on, and the output end of the first motor 5 drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the traction member 10 to move through the first connecting rod 8. Because the second connecting rod 9 limits the traction member 10, the second rotating shaft 7 deflects;

[0041] The vertical rod 1002 in the traction member 10 pulls the upper pusher 14 through the connecting end 15, and the pusher 14 drives the telescopic support rod 13 to move horizontally in the guide block 12, and drives the guide block 12 to move up and down in the guide slot 11;

[0042] The pusher 14 drives the push plate 16 to move synchronously, and drives the material forward a certain distance in the process of contacting the material, so as to realize step-by-step feeding.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
