[0031] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment 1

[0033] Please refer to Figures 1-7 The present embodiment aims to provide a jig for preventing material bending at the connection between a feeder and a main machine for small-diameter product processing. The jig comprises a feeder-side connecting pipe 1 arranged at one end of a feeder output pipe 3. First threaded grooves are symmetrically arranged at opposite sides of the feeder-side connecting pipe 1. The first threaded grooves are in communication with the inside of the feeder-side connecting pipe 1. First jackscrews 11 are threadedly connected to the inside of the first threaded grooves. The ends of the two first jackscrews 11 close to each other are in close contact with the feeder output pipe 3. The feeder output pipe 3 is clamped and fixed in the feeder-side connecting pipe 1 by the two first jackscrews 11. A main machine-side connecting pipe 2 is fixedly connected to one end of the feeder-side connecting pipe 1 through a flange. The end of the main machine-side connecting pipe 2 away from the feeder-side connecting pipe 1 is arranged in the inside of a main machine built-in pipe 4. A second threaded groove is arranged in the bottom of the main machine built-in pipe 4 and is in communication with the inside of the main machine built-in pipe 4. A second jackscrew 41 is threadedly connected to the inside of the second threaded groove. The upper end of the second jackscrew 41 is in close contact with the main machine-side connecting pipe 2. The main machine-side connecting pipe 2 is tightly fixed in the inside of the main machine built-in pipe 4 by the second jackscrew 41. When the feeder output pipe 3 discharges small raw materials, the small raw materials pass through the feeder-side connecting pipe 1 and the main machine-side connecting pipe 2 into the inside of the main machine built-in pipe 4 in sequence. The position of the inner wall of the main machine-side connecting pipe 2 close to the feeder-side connecting pipe 1 is designed to be trumpet-shaped. The inner diameter of the feeder-side connecting pipe 1 is smaller than the maximum inner diameter of the main machine-side connecting pipe 2. When the small raw materials enter the inside of the main machine-side connecting pipe 2 from the feeder-side connecting pipe 1, the small raw materials away from the axis of the feeder-side connecting pipe 1 will be in contact with the trumpet-shaped inner wall of the main machine-side connecting pipe 2. The trumpet-shaped inner wall changes the movement direction of the small raw materials in contact with it, ensuring that the small raw materials can smoothly enter the inside of the main machine built-in pipe 4, so that part of the small raw materials will not be discarded due to bending, and the continuous processing of the small raw materials is realized.

[0034] When the length of the feeder output pipe 3 is relatively long, the worker is easy to collide with the feeder output pipe 3 in the process of production and processing. When the position of the feeder output pipe 3 that is subjected to the collision is far away from the main machine side connecting pipe 2, the connection between the feeder side connecting pipe 1 and the main machine side connecting pipe 2 is subjected to a relatively large shearing force under the action of the lever. The flange subjected to the large shearing force is subjected to a non-recoverable deformation, which causes the connection between the feeder side connecting pipe 1 and the main machine side connecting pipe 2 to be loose or even to be separated. In order to solve this problem, it is referred to Figure 1 A reinforcing mechanism 5 is arranged between the feeder side connecting pipe 1 and the main machine side connecting pipe 2. The reinforcing mechanism 5 is used to enhance the connection strength between the feeder side connecting pipe 1 and the main machine side connecting pipe 2. When the feeder output pipe 3 is subjected to a collision, the connection between the feeder side connecting pipe 1 and the main machine side connecting pipe 2 is not easy to be loose or to be separated, which ensures the efficiency of the feeder side connecting pipe 1 and the main machine side connecting pipe 2 in conveying the small raw materials.

[0035] The structure of the reinforcing mechanism 5 is refined as follows. It is referred to Figure 3 The reinforcing mechanism 5 comprises a top plate 51 arranged above the flange. Both ends of the top plate 51 are fixedly connected with two side plates 52 in a symmetrical manner. The bottom of each side plate 52 is fixedly connected with two supporting plates 522 in a symmetrical manner at the middle position. The lower surface of each supporting plate 522 is arranged as an inner circular arc surface. The inner circular arc surfaces of the four supporting plates 522 are respectively in contact with the top of the feeder side connecting pipe 1 and the main machine side connecting pipe 2. Two T-shaped sliding grooves 521 are symmetrically arranged at the positions close to both ends of the bottom of each side plate 52. A T-shaped sliding block 55 is slidably arranged in each T-shaped sliding groove 521. A clamping plate 551 is fixedly connected to the lower end of each T-shaped sliding block 55. The side close to each other of the two clamping plates 551 is arranged as an inner circular arc surface. The T-shaped sliding groove 521 and the T-shaped sliding block 55 cooperatively limit the movement of the clamping plate 551 towards or away from the supporting plate 522. Meanwhile, a transmission shaft 53 is rotatably connected to the middle position of each side plate 52. A clamping assembly 56 is arranged between the transmission shaft 53 and each T-shaped sliding block 55. When the transmission shaft 53 rotates, the clamping assembly 56 drives the two T-shaped sliding blocks 55 to move close to or away from each other. A linkage assembly 54 is arranged on the top plate 51. The linkage assembly 54 is used to drive the two transmission shafts 53 to synchronously rotate. When the two transmission shafts 53 synchronously rotate, the two clamping assemblies 56 respectively drive the four T-shaped sliding blocks 55 to move close to the supporting plate 522. The four T-shaped sliding blocks 55 respectively drive the inner circular arc surfaces of the four clamping plates 551 to be in contact with the side walls of the feeder side connecting pipe 1 and the main machine side connecting pipe 2. At this time, the central axis of each clamping plate 551 is coaxially arranged with the feeder side connecting pipe 1 and the main machine side connecting pipe 2. The four clamping plates 551 cooperatively clamp and fix the top plate 51 and the two side plates 52 on the upper side of the feeder side connecting pipe 1 and the main machine side connecting pipe 2. The top plate 51, the two side plates 52, the four T-shaped sliding blocks 55 and the four clamping plates 551 cooperatively enhance the connection strength of the feeder side connecting pipe 1 and the main machine side connecting pipe 2.

[0036] In order to enable the worker to rotate two transmission shafts 53 at the same time, the structure of the linkage assembly 54 is detailed as follows, with reference to Figure 7 The transmission shaft 53 is coaxially and fixedly connected with a worm wheel 531 near the top end. The linkage assembly 54 includes a worm shaft 541 engaged with the two worm wheels 531, which is rotatably arranged on the upper side of the two side plates 52. The upper surface of the top plate 51 is fixedly connected with a bracket 511, which spans the upper side of the worm shaft 541. The linkage assembly 54 further includes a driving bevel gear 543 rotatably arranged on the top of the bracket 511. The worm shaft 541 is coaxially and fixedly connected with a driven bevel gear 542, which is engaged with the driving bevel gear 543. The rotation shaft of the driving bevel gear 543 extends above the bracket 511 and is fixedly connected with a crank 544. When the worker rotates the driving bevel gear 543 by holding the crank 544, the driven bevel gear 542 is driven to rotate through the engagement transmission of the driving bevel gear 543 and the driven bevel gear 542. The two worm wheels 531 are synchronously rotated through the engagement transmission of the worm shaft 541 and the two worm wheels 531. The rotated worm wheels 531 drive the corresponding transmission shafts 53 to rotate, so that the two transmission shafts 53 are synchronously rotated. This enables the worker to quickly clamp and fix the top plate 51 and the two side plates 52 on the upper side of the feeder side connecting pipe 1 and the main machine side connecting pipe 2, improving the disassembly and assembly efficiency of the top plate 51 and the two side plates 52.

[0037] In order to drive the two T-shaped sliders 55 to move closer to or away from each other, the structure of the clamping assembly 56 is detailed as follows, with reference to Figure 6 and Figure 7 The clamping assembly 56 includes a rotating plate 561 fixedly connected to the lower end of the transmission shaft 53. Both ends of the rotating plate 561 are rotatably connected with connecting rods 562. The other ends of the two connecting rods 562 are respectively hinged on the side of the two T-shaped sliders 55 that move closer to each other. The two connecting rods 562 are symmetrically distributed with the transmission shaft 53 as the center. The rotating plate 561 and the two connecting rods 562 form a Z-shaped structure. When the transmission shaft 53 rotates clockwise, the transmission shaft 53 drives the rotating plate 561 to rotate. The rotating rotating plate 561 drives one end of the two connecting rods 562 to rotate. The other end of the connecting rod 562 pulls the corresponding T-shaped slider 55, so that the T-shaped slider 55 moves along the inner wall of the T-shaped sliding groove 521 to the direction of approaching the supporting plate 522. When the transmission shaft 53 rotates counterclockwise, the other end of the connecting rod 562 pushes the corresponding T-shaped slider 55, so that the T-shaped slider 55 moves away from the supporting plate 522.

[0038] When the worker installs the reinforcing mechanism 5 on the feeder side connecting pipe 1 and the main machine side connecting pipe 2, first, the top plate 51 and the two side plates 52 are moved to the upper side of the flange, the feeder side connecting pipe 1 and the main machine side connecting pipe 2, so that the inner arc surfaces on the four supporting plates 522 are in contact with the side walls of the feeder side connecting pipe 1 and the main machine side connecting pipe 2 respectively, at this time, the inner arc surfaces on the four clamping plates 551 are located on the opposite sides of the feeder side connecting pipe 1 and the main machine side connecting pipe 2 respectively, then the worker rotates the handle 544 to make the two transmission shafts 53 rotate synchronously, so that the inner arc surfaces on the four clamping plates 551 are in contact with the side walls of the feeder side connecting pipe 1 and the main machine side connecting pipe 2 respectively, through the self-locking of the worm wheel 531 and the worm 541, the clamping plate 551 will not move away from the supporting plate 522 without rotating the handle 544, so as to clamp and fix the top plate 51 and the two side plates 52 on the upper side of the feeder side connecting pipe 1 and the main machine side connecting pipe 2, and enhance the connecting strength of the feeder side connecting pipe 1 and the main machine side connecting pipe 2.

[0039] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
