[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8In an embodiment of the present invention, an instrument part strength detection device for instrument production includes a workbench 1. A detection mechanism 2 for automatically calibrating and performing strength detection on instrument parts is arranged at the upper end of the workbench 1 near a fixing mechanism 3. The detection mechanism 2 includes a mounting frame 201. A hydraulic telescopic rod 202 is fixedly installed at the upper end of the mounting frame 201. A detection frame 203 is fixedly installed at the output end of the hydraulic telescopic rod 202. A high-pressure cylinder 204 is fixedly installed on the inner wall of the detection frame 203. A detection rod 205 is slidably arranged at the lower end of the cylinder. The detection mechanism 2 enables the instrument part to automatically change slowly with the detection rod 205 during the detection process, thereby making the detection result more accurate. A fixing mechanism 3 for holding the instrument part with a fixing clamp 309 is arranged at the upper end of the workbench 1 near the detection rod 205. The fixing structure prevents the instrument part from moving during the detection of the instrument part. A collecting mechanism 4 for discharging materials in linkage with the detection frame 203 is arranged at the upper end of the workbench 1 near the mounting frame 201. The collecting mechanism 4 makes it more convenient to take out the detected instrument parts.

[0034] See also Figures 1 to 3 , a mounting plate 206 is slidably mounted on the upper end of the mounting frame 201, and the hydraulic telescopic rod 202 is fixedly mounted on the lower end of the mounting plate 206, and a threaded rod 207 is fixedly mounted on the mounting plate 206 near the lower end of the hydraulic telescopic rod 202, and a threaded cylinder 208 is sleeved on the outer wall of the threaded rod 207. When the threaded cylinder 208 rotates, the threaded rod 207 starts to move up and down, thereby making it more convenient to adjust the height of the mounting plate 206, and a driven gear 209 is fixedly mounted on the outer wall of the threaded cylinder 208, and a limiting frame 210 is fixedly mounted on the inner wall of the mounting frame 201 near the threaded cylinder 208, and a driven gear 209 is fixedly mounted on the side end of the limiting frame 210. The adjusting motor 209 rotates, and a limiting rod 212 is fixedly installed on the output end of the adjusting motor 211, and the limiting rod 212 passes through the limiting frame 210, and a worm 214 is fixedly installed on the outer wall of the limiting rod 212 close to the driven gear 209, and the worm 214 is meshingly connected with the driven gear 209. When the height of the mounting plate 206 needs to be adjusted, the adjusting motor 211 is started to make the limiting rod 212 start to rotate, and the worm 214 drives the driven gear 209 to start to rotate, so that the threaded cylinder 208 starts to rotate, so that the threaded rod 207 starts to drive the mounting plate 206 to move up and down, thereby making it more convenient to adjust the height of the mounting plate 206.

[0035] See also Figures 1 to 7, sliding rods 215 are slidably installed at both ends of the mounting plate 206, and the sliding rods 215 are fixedly installed at the lower end of the mounting frame 201, and the detection frame 203 is slidably installed on the outer wall of the sliding rods 215, and the sliding rods 215 installed on the mounting frame 201 enable the detection frame 203 to move vertically along the sliding rods 215 during the up and down movement, thereby preventing the detection frame 203 from being offset and tilted when the hydraulic telescopic rod 202 pushes the detection frame 203 to start moving, and the high-pressure cylinder 204 is fixedly installed at the lower end of the detection frame 203, and the gas pressure filled in the high-pressure cylinder 204 is five standard atmospheres, a piston ring 217 is slidably installed inside the high-pressure cylinder 204, and the detection rod 205 is fixedly installed at the lower end of the piston ring 217, a moving block 218 is fixedly installed on the outer wall of the detection rod 205, a resistance rod 219 is fixedly installed on the upper end of the moving block 218, and a brush ring 229 is fixedly installed on the side end of the detection frame 203 close to the resistance rod 219 When the detection rod 205 drives the moving block 218 to start moving, the resistance rod 219 starts to slide in the inner wall of the brush ring 229, so that the resistance changes, and the brush ring 229 is slidably sleeved on the outer wall of the resistance rod 219, and the side end of the brush ring 229 is fixedly installed with a data line 220, and the end of the data line 220 away from the brush ring 229 is fixedly installed with a processor 221. The above-mentioned processor 221 is a prior art and will not be described in detail here. When the resistance output size starts to change, the changed resistance data is transmitted to the processor 221 through the data line 220. The processor 221 accurately calculates the moving distance of the detection rod 205 according to the resistance size, thereby calculating the existing air pressure size in the high-pressure cylinder 204, and thus obtaining the strength size of the instrument parts. The resistance calculation formula and the air pressure calculation formula are: R=ρL / S, where ρ represents the resistivity of the material, L represents the length of the conductor, and S represents the cross-sectional area of ​​the conductor;

[0036] p = F / S, where p represents pressure, F represents force, and S is the area under force. This formula expresses that pressure is the ratio between force and area under force. In practical applications, if the total pressure on an area and the size of the area are known, the pressure can be calculated using this formula.

[0037] See also Figures 1 to 8The outer wall of the detection rod 205 is sleeved with a connecting telescopic cylinder 222. The connecting telescopic cylinder 222 allows the detection rod 205 to detect the strength of the instrument part, and the mounting ring 223 still contacts the surface of the instrument part. When the detection rod 205 is inserted into the instrument part, the reaction is faster. The lower end of the connecting telescopic cylinder 222 is fixedly installed with a mounting ring 223, and the upper end of the mounting ring 223 is fixedly installed with a contact ring 224. The side end of the contact ring 224 is fixedly installed with a transmission line 225, and the end of the transmission line 225 away from the contact ring 224 is fixedly installed on the processor 221. At the input end, a mounting block 226 is fixedly mounted on the outer wall of the detection rod 205 close to the contact ring 224, and a power rod 227 is fixedly mounted on the lower end of the mounting block 226. A power ring 228 is fixedly mounted on the outer wall of the power rod 227. When the detection rod 205 and the mounting ring 223 are both placed on the surface of the instrument part, the power ring 228 and the contact ring 224 do not contact each other, leaving a slight gap. After the detection rod 205 is inserted into the instrument part, the power ring 228 moves downward, so that the contact ring 224 contacts the power ring 228, and the transmission line 225 contacts the data. The detection rod 205 starts to wear out and slowly shortens. Each time the contact ring 224 contacts the energized coil 228, the contact ring 224 contacts the energized coil 228. Ring 224 pushes the energized circle 228 to start moving slowly upward. After the energized circle 228 drives the moving circle 216 to move upward, the baffle 213 slides on the energized rod 227. When the baffle 213 stops sliding and the energized circle 228 wants to slide downward, the baffle 213 resists the energized rod 227. Therefore, when the strength of the instrument parts is detected and the detection rod 205 starts to slowly wear out, the energized circle 228 starts to slowly rise synchronously with the wear length of the detection rod 205. Therefore, after the detection device has been used for a long time to detect the strength of the instrument parts, the strength data of the instrument parts detected is more accurate.

[0038] See also Figures 1 to 5The fixing mechanism 3 includes a placing block 301, and the placing block 301 is fixedly installed on the upper end of the workbench 1 near the detection rod 205. The upper end of the placing block 301 near the detection rod 205 is fixedly installed with a detection table 302, and the side end of the detection table 302 away from the detection frame 203 begins to have a placing groove 303. The placing groove 303 provided on the detection table 302 makes it more convenient to take out the instrument parts after the instrument parts are detected. The upper end of the placing block 301 is fixedly installed with a retractable and lifting fixing frame 305, which is fixed The upper end of the frame 305 is fixedly installed with a fixed box 306. When the height position of the fixed box 306 needs to be adjusted, the fixed frame 305 is started, so that the fixed frame 305 drives the instrument parts to start moving up and down, and it is more convenient to place the instrument parts on the test bench 302. The side end of the fixed box 306 is fixedly installed with a fixed block 307. Both ends of the fixed block 307 are slidably installed with fixed rods 304, and the fixed rods 304 are all slidably arranged inside the fixed rods 304. The fixed rods 304 are away from the fixed blocks 307. A fixing clamp 309 is fixedly installed at one end, and an anti-sliding block 310 is fixedly installed at one end of the fixing clamp 309 away from the fixing rod 304. The anti-sliding block 310 provided on the fixing clamp 309 prevents the instrument parts from slipping during the clamping process after the fixing clamp 309 clamps and fixes the instrument parts. A protective sheet 311 is fixedly installed at the side end of the fixing clamp 309 close to the fixing block 307. When the protective sheet 311 causes the fixing clamp 309 to start moving and the fixing clamp 309 contacts the fixing block 307, The protective sheet 311 plays a buffering role to prevent the fixing clamp 309 from colliding with the fixing block 307 and causing damage. A connecting rod 312 is fixedly installed on the end of the fixing clamp 309 close to the fixing box 306, and a two-way telescopic rod 313 is fixedly installed between the connecting rods 312, and the two-way pneumatic rod is fixedly installed on the inner wall of the fixing box 306. When the two-way pneumatic rod starts to work, the two-way pneumatic rod drives the fixing clamp 309 to start moving through the connecting rod 312, thereby fixing the instrument parts on the upper end of the test bench 302.

[0039] See also Figures 1 to 5 An air intake telescopic tube 314 is fixedly installed at the input end of the two-way telescopic rod 313, and an air transfer tube 315 is fixedly installed at one end of the air intake telescopic tube 314 away from the two-way pneumatic rod, and a connecting telescopic tube 316 is fixedly installed at one end of the air transfer tube 315 away from the air intake telescopic tube 314. When the connecting telescopic tube 316 moves the detection frame 203 up and down, the connecting telescopic tube 316 will not be pulled and damaged when it is extended and retracted. An air intake pipe 317 is fixedly installed at one end of the connecting telescopic tube 316 away from the air transfer tube 315, and an end of the air intake pipe 317 away from the connecting telescopic tube 316 is fixedly installed at the upper end of the high-pressure cylinder 204. The connecting telescopic tube 316 prevents the high-pressure cylinder 204 from pulling the air intake pipe 317 during the up and down movement, thereby damaging the air intake pipe 317.

[0040] See also Figures 1 to 5 The collecting mechanism 4 includes a collecting box 401, and the collecting box 401 is fixedly mounted on the inner wall of the workbench 1, and a collecting gap is opened at the upper end of the workbench 1 away from the mounting frame 201. The collecting gap set on the workbench 1 makes it more convenient to transfer the instrument parts to the collecting box 401 after the detection is completed. The inner wall of the mounting frame 201 is fixedly mounted with a collecting bucket 402, so that the instrument parts are collected by the collecting bucket 402 and transferred to the collecting box 401 more conveniently. The upper end of the mounting frame 201 is fixedly mounted with a connecting block 403, and the upper end of the connecting block 403 is fixedly mounted. An air pump 404 is fixedly installed, and an air pump piston 405 is slidably installed on the inner wall of the air pump 404. An air pump rod 406 is fixedly installed on the lower end of the air pump piston 405. An air pump block 407 is fixedly installed on the side end of the detection frame 203 close to the connecting block 403, and the air pump rod 406 is fixedly installed on the upper end of the air pump block 407. When the hydraulic telescopic rod 202 is started and the detection frame 203 starts to move up and down, the air pump block 407 drives the air pump rod 406 to start moving up and down, so that the air pump piston 405 starts to move, and the air pressure in the air pump 404 is discharged.

[0041] See also Figures 1 to 5 , an air outlet pipe 408 is fixedly installed at the output end of the air pump 404, and an air nozzle 409 is fixedly installed at one end of the air outlet pipe 408 away from the air pump 404, and the air injection end of the air nozzle 409 is arranged at the lower end of the placement groove 303, and a pressure relief valve 410 is fixedly installed at the air outlet end of the air nozzle 409. When the air pressure of the air pump 404 starts to squeeze the transmission, the air pressure is transmitted to the air nozzle 409 through the air outlet pipe 408, and the air pressure begins to increase. When the air pressure exceeds the limit value of the pressure relief valve 410, the pressure relief valve 410 opens and the air pressure is ejected, thereby blowing the instrument parts that have been inspected on the inspection table 302 into the collection bucket 402, and then enter the collection box 401 through the collection bucket 402, so that the collection of the instrument parts that have been inspected is more convenient, and a handle 411 is arranged at the control end of the pressure relief valve 410. The handle 411 arranged at the control end of the pressure relief valve 410 makes it more convenient to adjust the size of the air pressure ejected by the pressure relief valve 410.

[0042] The working principle of the present invention is: when it is necessary to detect instrument parts, the instrument parts are placed on the detection table 302, the fixing frame 305 is moved to a suitable height, the fixing clamp 309 is moved to a suitable height, the hydraulic telescopic rod 202 is started, and the hydraulic telescopic rod 202 pushes the detection frame 203 to move downward. When the detection rod 205 and the mounting ring 223 are in contact with the instrument parts, the detection rod 205 and the mounting ring 223 are both placed on the surface of the instrument parts, and the power-on circle 228 and the contact ring 224 are not in contact, leaving a slight gap. After the hydraulic telescopic rod 202 continues to push the detection frame 203, the instrument parts push the detection rod 205 and the mounting ring 223 to move, so that the connecting telescopic cylinder 222 begins to shrink, and the detection rod 205 drives the moving block 218 to move upward, so that the resistance rod 219 moves upward. The resistance rod 219 starts to slide in the inner wall of the brush ring 229, thereby changing the resistance. The changed resistance data is transmitted to the processor 221 through the data line 220. The processor 221 accurately calculates the moving distance of the detection rod 205 and the existing air pressure in the high-pressure cylinder 204 through the resistance. When the detection rod 205 and the mounting ring 223 are both placed on the surface of the instrument part, the power-on circle 228 and the contact ring 224 are not in contact, leaving a slight gap. After the detection rod 205 is inserted into the instrument part, the power-on circle 228 moves downward, causing the contact ring 224 to contact the power-on circle 228. The transmission line 225 transmits the contact data to the processor 221, causing the processor 221 to stop the hydraulic telescopic rod 202 from working, thereby making the detected detection data more accurate.

[0043] When the detection rod 205 pushes the piston ring 217 to start moving upward to squeeze the gas in the high-pressure cylinder 204, the air pressure in the high-pressure cylinder 204 begins to increase, and the air pressure is transmitted to the connecting telescopic tube 316 through the air intake pipe 317, and the air pressure is then transmitted to the two-way telescopic rod 313 through the air intake telescopic tube 314, so that the fixed clamp 309 clamps the instrument parts and fixes them, thereby increasing the detection force during the detection process. When the air pressure in the high-pressure cylinder 204 increases, the fixed clamp 309 clamps the instrument parts with greater force, thereby making the detection of instrument parts more stable.

[0044] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
