[0002] Traditional hardware products, also known as "small hardware", refer to five metals: gold, silver, copper, iron and tin. They can be made into works of art or metal devices such as knives and swords through manual processing. Hardware in modern society is more extensive, such as hardware tools, hardware parts, daily hardware, construction hardware and security products. Some of the L-shaped hardware parts often need to be knocked on one side during processing to ensure the safety of subsequent use to detect whether the strength of the bent part is qualified. However, the existing testing facilities only use clamping to fix the workpiece during use. This operation method is very likely to cause loose clamping and subsequent displacement of the workpiece during knocking, which seriously affects the accuracy of strength testing. In addition, the workpiece is also very likely to fly out of the workbench due to knocking, which poses a great safety hazard. Summary of the invention

DETAILED DESCRIPTION

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] like Figure 1-Figure 6 The strength detection device for hardware production shown in the figure includes a mounting base 1, and a fixing base 11 is fixedly installed at the upper end of the mounting base 1 near the edge. The fixing base 11 plays the role of supporting the workpiece 37. The upper end surface of the fixing base 11 is provided with a fixing groove 13. The thickness of the fixing groove 13 matches that of the workpiece 37 to ensure that the workpiece 37 will not shake after being placed in. The fixing groove 13 extends to the front and rear end surfaces of the fixing base 11. On the one hand, it can facilitate the positioning ear 12 to extend into the fixing groove 13 to limit the workpiece 37. On the other hand, it can ensure that the workpiece 37 is normally placed in the fixing groove 13, and at the same time, the knocked edge of the workpiece 37 is located between the upper block seat 15 and the lower block seat 16, and the knocked edge of the workpiece 37 does not contact the upper block seat 15 and the lower block seat 16, so as to ensure that the workpiece 37 is placed in the fixing groove 13 normally. In order to avoid being supported by the upper stop seat 15 and the lower stop seat 16 during knocking, which would affect the detection accuracy, two fixing rods 21 are symmetrically and elastically installed on one side of the fixing seat 11. The diameter of the fixing rod 21 matches the aperture of the mounting hole on the workpiece 37 to ensure that the workpiece 37 will not shake after the fixing rod 21 is inserted. The fixing rod 21 passes through the interior of the fixing groove 13, and the upper end of the fixing seat 11 and the upper end of the mounting carrier 1 are installed with anti-flying parts. A knocking piece is installed near the middle of the upper end of the mounting carrier 1, and a positioning ear 12 is fixedly installed at the rear end of the fixing seat 11. The end of the positioning ear 12 extends into the fixing groove 13. The positioning ear 12 can limit the workpiece 37 when it is placed, so that the fixing rod 21 can be accurately and quickly aligned with the mounting hole on the workpiece 37 and pass through.

[0024] Two reinforcement holes 18 are symmetrically provided on both sides of the interior of the fixing groove 13, and the reinforcement holes 18 extend to the end surfaces of both sides of the fixing seat 11. The reinforcement holes 18 can limit the fixing rod 21 to increase the force on the fixing rod 21, that is, to increase the fixing force of the fixing rod 21 on the workpiece 37. The fixing rod 21 fits inside the reinforcement hole 18, and a guide sleeve 22 is fitted on the outer surface of the fixing rod 21. The guide sleeve 22 is connected to the fixing seat 11, and the guide sleeve 22 plays a role in guiding the fixing rod 21. The outer surfaces of the two fixing rods 21 are coaxially inlaid with push caps 24, which are located on the side of the guide sleeve 22, and the push caps 24 are fitted on one side of the fixing seat 11, and the push caps 24 play a role of being pushed by the spring body 19.

[0025] A pull frame 23 is fixedly installed between the two push caps 24. The pull frame 23 is pulled to make the fixing rod 21 move sideways to disengage from the fixing groove 13. At the same time, the spring body 19 contracts and deforms. Then, the workpiece 37 is pushed into the fixing groove 13 from the front. At this time, the workpiece 37 moves in contact with the bottom of the fixing groove 13. When the workpiece 37 is in contact with the end of the positioning ear 12, the pull frame 23 is released to make the spring body 19 recover its deformation to push the fixing rod 21, so that the fixing rod 21 can pass through the two mounting holes on the workpiece 37 to firmly restrict the workpiece 37 in the fixing groove 13. The end of the pull frame 23 is fixed. A pull ring 25 is installed, and the pull frame 23 serves to pull the two fixed rods 21 at the same time. The pull ring 25 serves to facilitate the holding of the pull frame 23. A spring body 19 is wrapped around the outside of the fixed rod 21. One end of the spring body 19 is fixed to the guide sleeve 22, and the other end of the spring body 19 is fixed to the push cap 24. The spring body 19 serves to push the fixed rod 21 to pass through the fixed groove 13. A fixed sleeve frame 20 is fixedly installed on the outer surface of the guide sleeve 22. The end of the fixed sleeve frame 20 is fixed to the fixing seat 11, and the fixed sleeve frame 20 serves to fix the guide sleeve 22.

[0026] The anti-flying part includes an extending frame 14 fixedly installed at the upper end edge of the fixing seat 11, and the end of the extending frame 14 is fixedly installed with a concave frame 30, and the extending frame 14 plays the role of supporting and fixing the concave frame 30, and both ends of the concave frame 30 are fixedly installed with an upper bearing seat 31, and the concave frame 30 plays the role of fixing the upper bearing seat 31, and an upper stop seat 15 is connected directly below the upper bearing seat 31, and the upper stop seat 15 plays the role of preventing the broken workpiece 37 from flying upward.

[0027] Two upper guide posts 33 are symmetrically fixedly installed on the upper end of the upper stop seat 15, and the upper guide posts 33 pass through the upper end of the upper bearing seat 31. The upper guide posts 33 play a role in guiding the upper stop seat 15. The upper guide posts 33 are slidably matched with the upper bearing seat 31, and the upper end of the upper guide posts 33 is coaxially inlaid with an upper anti-slip ring 32. The upper anti-slip ring 32 plays a role in preventing the upper guide posts 33 and the upper bearing seat 31 from separating. The upper anti-slip ring 32 fits the upper end of the upper bearing seat 31, and an upper buffer spring 34 is wound around the outer side of the upper guide post 33. The lower end of the upper buffer spring 34 is fixed to the upper stop seat 15. The upper buffer spring 34 can offset the force impacting the upper stop seat 15, and the upper end of the upper buffer spring 34 is fixed to the lower end of the upper bearing seat 31.

[0028] Two lower guide posts 27 are symmetrically fixedly installed at the lower end of the lower stop seat 16, and the lower guide posts 27 pass through the lower end of the lower bearing seat 26. The lower guide posts 27 play a role in guiding the lower stop seat 16, and the lower guide posts 27 are slidably matched with the lower bearing seat 26. The lower end of the lower guide post 27 is coaxially inlaid with a lower anti-slip ring 28, and the lower anti-slip ring 28 is fitted to the lower end of the lower bearing seat 26. The lower anti-slip ring 28 prevents the lower guide post 27 and the lower bearing seat 26 from separating, and a lower buffer spring 29 is wound around the outer side of the lower guide post 27, and the upper end of the lower buffer spring 29 is fixed to the lower stop seat 16. The lower buffer spring 29 plays a role in offsetting the force impacting the lower stop seat 16, and the lower end of the lower buffer spring 29 is fixed to the upper end of the lower bearing seat 26.

[0029] The knocking piece includes two shaft brackets 2 symmetrically fixedly installed on the upper end of the mounting base 1 near the middle, a driving shaft 3 is rotatably installed between the upper ends of the two shaft brackets 2, the shaft bracket 2 plays a role in bearing the driving shaft 3, a knocking arm 4 is fixedly installed in the middle of the outer surface of the driving shaft 3, the driving shaft 3 plays a role in driving the knocking arm 4 to rotate for knocking, and two knocking hammer heads 5 are symmetrically fixedly installed on the end of the knocking arm 4, the two knocking hammer heads 5 can knock on the workpiece 37 from the top and the bottom respectively, both sides of the shaft bracket 2 are obliquely fixedly installed with a reinforcement frame 35, the end of the reinforcement frame 35 is fixed to the mounting base 1, the reinforcement frame 35 plays a role in reinforcing the shaft bracket 2, an arc groove 10 is opened near the middle of the upper end surface of the mounting base 1, the arc groove 10 is located between the two shaft brackets 2, and the arc groove 10 plays a role in allowing the knocking arm 4 to rotate normally.

[0030] A large gear 6 is coaxially fixedly installed on the rear end of the driving shaft 3, and two mounts 36 are symmetrically fixedly installed at the rear end edge of the mounting base 1. The mount 36 supports and fixes the motor base 9. A motor base 9 is fixedly installed on the end of the mount 36, and a servo motor 8 is fixedly installed on the upper end of the motor base 9. The motor base 9 fixes the servo motor 8. A small gear 7 is coaxially fixedly installed on the output end of the servo motor 8. The servo motor 8 can drive the knocking arm 4 to rotate forward or reverse, that is, to achieve the purpose of knocking the workpiece 37 from above or below. At the same time, the speed of the servo motor 8 can be adjusted to change the force of the knocking. Since adjusting the speed of the motor is a prior art, it is not elaborated here in detail. The small gear 7 is meshed with the large gear 6, and the small gear 7 and the large gear 6 play a role in transmission and increasing torque.

[0031] During the inspection, the puller 23 is directly pulled to make the fixing rod 21 move sideways to disengage from the fixing groove 13, and the spring body 19 contracts and deforms, and then the workpiece 37 is pushed into the fixing groove 13 from the front. At this time, the workpiece 37 moves in contact with the bottom of the fixing groove 13. When the workpiece 37 is in contact with the end of the positioning ear 12, the puller 23 is released to make the spring body 19 recover its deformation to push the fixing rod 21, so that the fixing rod 21 can pass through the two mounting holes on the workpiece 37 to firmly restrict the workpiece 37 in the fixing groove 13. At this time, the struck edge of the workpiece 37 is just between the upper stopper 15 and the lower stopper 16, and then the servo motor 8 works through the small gear 7 and the large gear 6 to drive The driving shaft 3 rotates, thereby driving the striking hammer head 5 on the striking arm 4 to rotate, so as to strike one side of the workpiece 37 from the top and the bottom respectively. When the workpiece 37 is not deformed after the striking, it indicates that the strength of the workpiece 37 is qualified. If the workpiece 37 is deformed or broken after the striking, it indicates that the strength of the workpiece 37 is unqualified. When the strength of the workpiece 37 is unqualified and breaks, the upper block seat 15 and the lower block seat 16 can block the broken workpiece 37. At the same time, the upper buffer spring 34 and the lower buffer spring 29 offset the force hitting the upper block seat 15 and the lower block seat 16, so as to prevent the broken workpiece 37 from flying out due to the striking force and causing safety hazards.
