During this period, the clamped rods may fall out of the clamping grooves, and then need to be realigned and clamped, which is cumbersome and labor-intensive. Therefore, a positioning transmission device for chair furniture processing is needed to solve the above problems. Utility Model Content

Two notches are penetrated inside the lower pressure block, and a pressure roller is arranged inside each of the notches. First connecting blocks are rotatably connected to both sides of the pressure roller, and sliding rods are fixedly connected to the lower surfaces of the two first connecting blocks, and the bottom end of each sliding rod is fixedly connected to a limiting block. A plurality of second connecting blocks are fixedly connected to the lower surface of the lower pressure block, and one end of each sliding rod is respectively penetrated and slidably connected to the corresponding second connecting block, and a spring is sleeved on the outside of each sliding rod.

[0006] By setting the above structure, when the rod is placed on the lower pressing block, the hydraulic rod will drive the lower pressing block close to the upper pressing block under the operation of the hydraulic rod, and the rod will be clamped by the lower pressing block and the upper pressing block. During this period, the pressure roller in the lower pressing block will retract into the notch due to the pressure on the surface of the rod, so that the rod can be clamped more firmly by the lower pressing block and the upper pressing block. When a section of the rod needs to be extended for cutting after cutting, the lower pressing block can be slightly moved downward by the extension and contraction of the hydraulic rod. At this time, the pressure roller will be driven by the sliding rod and the first connecting block to be close to the lower surface of the rod under the rebound of the spring, and the rod will be propped up, so that the rod can maintain the original clamping position when the lower pressing block moves downward to a certain extent. At this time, when pushing the extended rod, the rod will not only not fall off, but also can be easily extended and pushed through the rotation of the pressure roller, which is more convenient and labor-saving.

[0011] As a preferred implementation, a double-headed electric push rod is fixedly connected to the fixed block, and two ends of the double-headed electric push rod are respectively fixedly connected to adjacent sides of the two moving columns.

[0012] By setting a feed roller, when the second motor is started, the feed roller can be driven to rotate on one side to feed the material. Combined with the position of the rod being stationary when the lower pressure block moves slightly downward, longer rods can be automatically fed during cutting, which helps save manpower.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model, by setting the above structure, when the rod is placed on the lower pressing block, the hydraulic rod will drive the lower pressing block to approach the upper pressing block under the operation of the hydraulic rod, and the rod will be clamped by the lower pressing block and the upper pressing block. During this period, the pressure roller in the lower pressing block will retract into the notch due to the pressure on the surface of the rod, so that the rod can be clamped more firmly by the lower pressing block and the upper pressing block. When the rod needs to be extended after a section of cutting is completed, the lower pressing block can be slightly moved downward by the extension and contraction of the hydraulic rod. At this time, the pressure roller will be driven by the sliding rod and the first connecting block to be tightly attached to the lower surface of the rod under the rebound of the spring, and the rod will be propped up, so that the rod can maintain the original clamping position when the lower pressing block moves downward to a certain extent. At this time, when pushing the extended rod, the rod will not only not fall off, but also can be easily extended and pushed through the rotation of the pressure roller 12, which is more convenient and labor-saving.

[0015] The utility model provides a feeding roller. When the second motor is started, the feeding roller can be driven to rotate on one side for feeding. When the lower pressing block moves downward slightly, the position of the rod remains unchanged. This allows longer rods to be automatically fed during cutting, thereby helping to save manpower.

The connecting frame 9 is fixedly connected with an upper pressing block 10, which corresponds to the lower pressing block 7. Two notches 11 are formed inside the lower pressing block 7, and a pressing roller 12 is arranged inside each notch 11. Both sides of the pressing roller 12 are rotatably connected with a first connecting block 13. The lower surfaces of the two first connecting blocks 13 are fixedly connected with a sliding rod 14, and the bottom end of each sliding rod 14 is fixedly connected with a limiting block 24. The lower surface of the lower pressing block 7 is fixedly connected with a plurality of second connecting blocks 15, and one end of each sliding rod 14 is fixedly connected with a limiting block 24. The ends are respectively penetrated and slidably connected in the corresponding second connecting block 15. The outside of each sliding rod 14 is sleeved with a spring 16. By setting the above structure, when the rod is placed on the lower pressing block 7, the hydraulic rod 6 will drive the lower pressing block 7 to approach the upper pressing block 10, and the rod will be clamped by the lower pressing block 7 and the upper pressing block 10. During this period, the pressing roller 12 in the lower pressing block 7 will retract into the notch 11 due to the pressure on the surface of the rod, so that the rod can be clamped more firmly by the lower pressing block 7 and the upper pressing block 10. When the rod needs to be extended and cut after a section of cutting is completed, the lower pressing block 7 can be slightly moved downward by the extension and contraction of the hydraulic rod 6. At this time, under the rebound of the spring 16, the sliding rod 14 and the first connecting block 13 will drive the pressure roller 12 to be close to the lower surface of the rod and prop up the rod, so that the rod can maintain the original clamping position when the lower pressing block 7 moves downward to a certain extent.

[0029] A second motor 21 is disposed at the rotational position of the two feeding rollers 20 , and a fixing block 22 is fixedly connected to the machine platform 1 .

[0030] A double-headed electric push rod 23 is fixedly connected to the fixed block 22, and both ends of the double-headed electric push rod 23 are respectively fixedly connected to the adjacent sides of the two movable columns 18. By setting a feeding roller 20, when the second motor 21 is started, the feeding roller 20 can drive the feeding roller 20 to rotate on one side. Combined with the position of the rod being stationary when the lower pressing block 7 moves slightly downward, longer rods can be automatically loaded during cutting, which helps to save manpower.

[0031] The working principle and use process of the utility model are as follows: first, when the rod is placed on the lower pressing block 7, the hydraulic rod 6 will drive the lower pressing block 7 to approach the upper pressing block 10, and the rod will be clamped by the lower pressing block 7 and the upper pressing block 10. When the first motor 4 is started, the displacement block 5 is displaced by the rotation of the threaded rod 3 under the power output of the first motor 4, and the displacement block 5 drives the rod clamped by the lower pressing block 7 and the upper pressing block 10 to be displaced through the hydraulic rod 6. During this period, the rod will drive the connecting frame 9 to synchronously displace on the displacement frame 2 through friction, and then can be displaced to adjust a certain processing position. In addition, the pressure roller 12 in the lower pressing block 7 will retract into the notch 11 due to the pressure on the surface of the rod, so that the rod can be clamped more firmly by the lower pressing block 7 and the upper pressing block 10. When a section of the rod is cut and needs to be extended for cutting, the lower pressing block 7 can be moved by the hydraulic rod 6 is slightly extended and moved downward. At this time, under the rebound of the spring 16, the sliding bar 14 and the first connecting block 13 drive the pressing roller 12 to be close to the lower surface of the rod and prop up the rod, so that the rod can maintain the original clamping position when the lower pressing block 7 moves downward to a certain extent. At this time, when pushing the extended rod, the rod will not only not fall, but also can be easily extended and pushed by the rotation of the pressing roller 12, which is more convenient and labor-saving. In addition, by setting the feeding roller 20, when the second motor 21 is started, the feeding roller 20 can be driven to rotate on one side of the feeding, and the position of the rod does not move when the lower pressing block 7 moves slightly downward, so that the longer rod can be automatically loaded when cutting, and the two feeding rollers 20 can be released from the conveying state through the extension and retraction of the double-headed electric push rod 23, so as to facilitate the initial clamping and loading of the rod.
