[0038] The utility model is further described below in conjunction with the accompanying drawings:

[0039] Example 1: Figure 1As shown, an adjustment device for crutch processing includes a frame 1, on which a gantry 6 is fixedly arranged, and is characterized in that a forming mechanism 4 and a punching mechanism 5 are arranged on the gantry 6, and a feeding mechanism 2 and a positioning mechanism 3 are arranged on the frame 1, the positioning mechanism 3 is located on the inner side of the gantry 6, and the feeding mechanism 2 passes through the output end of the positioning mechanism 3.

By moving the pitch-changing cylinder 203 up and down, the inclined steps on the pitch-changing bracket 204 can be used to separate the crutch bodies close together on the feed rack 202 one by one at a certain distance, ensuring that the crutch bodies can enter each groove. A sensor 209 for detecting whether a crutch body is placed on the groove is arranged between the support rack 205, wherein there are at least three lifting cylinders 210, the support rack 205, the feeding cylinder 208 and two of the lifting cylinders 210 are all arranged on the frame 1, and the other lifting cylinder 210 is connected to the output end of the feeding cylinder 208, and the feeding rack 206 is fixedly arranged at the output end of the lifting cylinder 210, and feeding is carried out by the mutual cooperation of the lifting cylinder 210 and the feeding cylinder 208.

An adjusting screw 303 is arranged on the adjusting seat 301. One end of the adjusting screw 303 is rotatably connected to the frame 1. The position of the adjusting seat 301 is adjusted by using the adjusting screw 303 to meet the positioning processing of crutch bodies of different lengths. There are two positioning frames 302, each of which is provided with a first oil cylinder 308. The output end of the first oil cylinder 308 is fixedly provided with a first punching die 304. One of the positioning frames 302 is slidably set on the frame 1, and the other positioning frame 302 is slidably installed on the adjusting seat 301. An adjusting cylinder is also arranged on the gantry 6 and the adjusting seat 301. The output end of the adjusting cylinder is connected to the relative positioning frame 302. The cooperation of the adjusting cylinder and the first punching die 304 can fix the crutch body and perform punching processing on the end. The first oil cylinder 308 can provide sufficient power for the first punching die 304.

[0045] like Figure 6 As shown, the forming mechanism 4 includes a lower die base 405, an upper die 401 and a forming cylinder 402. The lower die base 405 is fixedly arranged on the frame 1, the forming cylinder 402 is fixedly arranged on the gantry 6, the upper die 401 is fixedly arranged on the forming cylinder 402 and matched with the lower die base 405. The forming cylinder 402 pushes the upper die 401 toward the lower die base 405 so as to plasticize the crutch body placed between the upper die 401 and the lower die base 405. A second cylinder 403 is also fixedly arranged on the upper die 401 and the lower die base 405, and a second punching die 404 is fixedly arranged on the output end of the second cylinder 403. The two second punching dies 404 are positioned opposite to each other and matched with each other, so that the crutch body can be punched while being plasticized, which is convenient for later assembly.

[0046] The punching mechanism 5 includes an upper sliding frame 507, a lower sliding frame 508, an upper oil cylinder 506, a lower oil cylinder 503, an upper punching die 504, a lower punching die 501, an upper adjusting rod 505 and a lower adjusting rod 502. The lower sliding frame 508 is slidably arranged on the frame 1, the lower oil cylinder 503 is fixedly arranged on the lower sliding frame 508, the lower punching die 501 is fixedly arranged at the output end of the lower oil cylinder 503, and the lower adjusting rod 502 is installed on the frame 1, and one end of the lower adjusting rod 502 is connected to the lower sliding frame 508; the upper sliding frame 507 is slidably arranged on the frame 1, the lower oil cylinder 503 is fixedly arranged on the lower sliding frame 508, the lower punching die 501 is fixedly arranged at the output end of the lower oil cylinder 503, and the lower adjusting rod 502 is installed on the frame 1, and one end of the lower adjusting rod 502 is connected to the lower sliding frame 508; It is placed on the gantry 6, the upper oil cylinder 506 is fixedly set on the upper sliding frame 507, the upper punching die 504 is fixedly set at the output end of the upper oil cylinder 506, the upper adjusting rod 505 is set on the gantry 6, and one end is rotatably connected to the upper sliding frame 507. The upper adjusting rod 505 is used to adjust the position of the upper sliding frame 507 on the gantry 6, and the lower adjusting rod 502 can be used to adjust the position of the lower sliding frame 508 on the frame 1, which can meet the punching processing needs of crutch bodies of different lengths.

[0047] The working process of this embodiment: when processing, it is necessary to first rotate the adjusting screw 303, the upper adjusting rod 505 and the lower adjusting rod 502 to adjust the position of the adjusting seat 301 on the positioning mechanism 3 and the upper punching die 504 and the lower punching die 501 of the punching mechanism 5 to match the length of the armpit stick that needs to be processed.

[0048] Then put the main support rod required for processing the armpit stick on the feed rack 202, adjust the length of the adjusting support rod 201, so that the adjusting support rod 201 lifts the feed rack 202 and forms an angle with the supporting rack 205. When the length of the adjusting support rod 201 is extended, the angle between the feed rack 202 and the supporting rack 205 will become smaller; when the length of the adjusting support rod 201 is shortened, the angle between the feed rack 202 and the supporting rack 205 will become larger; by adjusting the angle between the feed rack 202 and the supporting rack 205, the main support rods can be neatly arranged one by one on the feed rack 202.

[0049] When the main support rod moves along the feed rack 202 to the support rack 205, the first main support rod will be stuck in the groove on the support rack 205 close to the feed rack 202. At this time, the other main support rods on the feed rack 202 will stop moving. At the same time, the pitch-changing cylinder 203 will drive the pitch-changing bracket 204 to move up and down. When the pitch-changing bracket 204 moves up and down, the main support rod stuck in the groove can be lifted up by the inclined steps. The main support rod lifted by the pitch-changing bracket 204 will slide along the steps on the pitch-changing bracket 204 until it is stuck. When the pitch-changing bracket 204 moves down, the main support rod lifted by the pitch-changing bracket 204 will enter the adjacent groove on the bracket. In this way, the pitch-changing cylinder 203 continuously pushes the pitch-changing bracket 204 up and down to move, so that the main support rods can be transferred to other grooves respectively, thereby avoiding the main support rods from being too closely fitted to affect the processing.

[0050] When all sensors 209 installed between the variable pitch bracket 204 and the bracket 205 detect that there are main support rods in the corresponding grooves, the lifting cylinder 210 pushes the feeding rack 206 to move upward, lifts the main support rod on the bracket 205, and then the feeding cylinder 208 extends, pushing the slide 211 to slide along the main slide rail 207, and at the same time, the feeding cylinder 208 will also drive the lifting cylinder 210 to slide along the auxiliary slide rail 213. When the main support rod moves between the two positioning racks 302 of the positioning mechanism 3, the feeding cylinder 208 stops extending, and at the same time all the lifting cylinders 210 shorten, so that the feeding rack 206 moves downward, and the main support rod is placed on the bracket 205 between the two fixed plates, and then the feeding cylinder 208 shortens, driving the feeding rack 206 and the lifting cylinder 210 to reset.

[0051] When the main support rod is moved between the two fixed plates by the feeding rack 206, the two positioning cylinders 307 installed on the gantry 6 and the adjustment seat 301 extend at the same time, pushing the two positioning racks 302 to move relative to each other along the positioning slide rails 306 until the first punching die 304 on the positioning rack 302 contacts the two ends of the main support rod to position and fix the main support rod. At the same time, the first oil cylinder 308 will also extend, pushing the first punching die 304 to punch the two ends of the main support rod.

[0052] After the positioning mechanism 3 positions and fixes the main support rod, the forming mechanism 4 and the punching mechanism 5 process the main support rod.

[0053] The forming cylinder 402 on the forming mechanism 4 will extend and push the upper mold 401 downward to shape the main support rod after closing the mold with the lower mold base 405. While the upper mold 401 and the lower mold base 405 are closing the mold, the two opposite second punching molds 404 will also be closed. At the same time, the second cylinder 403 will extend and push the two second punching molds 404 to perform punching while shaping the main support rod.

[0054] The upper oil cylinder 506 and the lower oil cylinder 503 on the punching mechanism 5 will extend at the same time, pushing the upper punching die 504 and the lower punching die 501 to close the die to perform punching processing on the main support rod.

[0055] After the main support rod is completed with plasticity and punching processing, the forming mechanism 4 and the punching mechanism 5 will be separated first, and then the two positioning frames 302 on the positioning mechanism 3 will move toward each other along the positioning slide rail 306, and the lifting cylinder 210 will push the feeding frame 206 to move up, and the main support rod after processing and the variable distance bracket 204 when the forming mechanism 4 and the punching mechanism 5 are working will be moved to the main support rod on the bracket 205 again for moving, and the unprocessed main support rod will be moved between the positioning mechanism 3, the forming mechanism 4 and the punching mechanism 5 for processing, and the processed main support rod will be transmitted to the end of the bracket 205, and finally will be along Figure 4The triangular bracket at the end of the middle bracket 205 slides down.

[0056] In this embodiment, the pressure rod 305 installed on the positioning frame 302 connected to the adjustment seat 301 can prevent the upper punching die 504 from getting stuck with the main support rod after the punching is completed, thereby preventing the upper punching die 504 from moving upward when the upper oil cylinder 506 drives the upper punching die 504 to reset, causing the main support rod to deform.

[0057] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
