[0016] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0017] like Figure 1 The diagram shown is a structural schematic of the screw thread rolling floating detection device provided by this utility model. The screw thread rolling floating detection device includes a machine base 10, a feeding assembly 20 disposed on one side of the machine base 10, and a detection assembly 30 disposed on the machine base 10. It is conceivable that the screw thread rolling floating detection device also includes other functional modules, such as a power supply module, a control module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0018] Please refer to the following: Figures 2 to 4 The machine base 10 is the body of the screw thread rolling machine. The working principle of the screw thread rolling machine itself is existing technology and will not be described in detail here. The machine base 10 is equipped with a feeding rail 11. One end of the feeding rail 11 is equipped with a movable thread plate 12 and a fixed thread plate 13 fixed on the machine base 10. The screw enters from the feeding rail 11 into the movable thread plate 12 and the fixed thread plate 13. The head of the screw is supported by the movable thread plate 12 and the fixed thread plate 13. The movable thread plate 12 moves back and forth to roll the threads of the screw and output the screw.

[0019] The feeding assembly 20 includes a material channel 21 disposed on one side of the machine platform 10, a support plate 22 mounted on the material channel 21, a baffle 23 hung on the side of the support plate 22 away from the machine platform 10, and a receiving box 24 disposed at the end of the material channel 21 away from the machine platform 10.

[0020] The feed channel 21 is inclined, with its input end located at the end of the fixed tooth plate 13 away from the feed track 11, so that the screws after the teeth are rolled can fall onto the feed channel 21 and roll into the receiving box 24 for receiving the screws.

[0021] The support plate 22 is arranged at the middle section of the material channel 21, i.e. the material channel 21 penetrates through the material channel 21. An iron wire 25 is fixedly arranged between the two inner side walls of the material channel 21, and is located at the side of the baffle 23 away from the support plate 22. The distance between the iron wire 25 and the material channel 21 can be adjusted by a screw. The baffle 23 is hung on the support plate 22 and located directly above the material channel 21. The width of the baffle 23 matches the width of the material channel 21. Two screws 26 are arranged on the baffle 23 at intervals. The head of each screw 26 is spaced apart from the baffle 23. Thus, the baffle 23 falls off the support plate 22 under the action of the detection assembly 30. The gap between the head of the screw 26 and the baffle 23 is hung on the iron wire 25, thereby blocking the passage of the material channel 21 to prevent defective products from falling into the receiving box 24.

[0022] The detection assembly 30 includes an adjusting assembly 31, an electromagnetic switch 32 arranged on the support plate 22, and a detection rod 33 arranged at the output end of the adjusting assembly 31.

[0023] The adjusting assembly 31 includes an X-axis support rod 311 arranged on the machine table 10, an adjusting block 312 sleeved on the X-axis support rod 311, and a Y-axis support rod 313 penetrating through the adjusting block 312.

[0024] The X-axis support rod 311 is fixedly arranged at one side of the die plate 13. The adjusting block 312 is movably sleeved on the X-axis support rod 311 and is fixed by a countersunk screw. Thus, by changing the position of the adjusting block 312 on the X-axis support rod 311, the height of the detection rod 33 can be changed, thereby adjusting the detection specifications of different types of screws and improving the applicability of the device.

[0025] The Y-axis support rod 313 is movably penetrated through the adjusting block 312 and is fixed by a countersunk screw. Thus, by changing the position of the Y-axis support rod 313 on the adjusting block 312, the distance between the detection rod 33 and the die plate 13 can be changed, thereby adjusting the placement position of the detection rod 33 so as to enable detection of screws.

[0026] The electromagnetic switch 32 is a switch controlled by an electromagnet, that is, a combination of electromagnet and switch. When the electromagnet coil is energized, electromagnetic attraction is generated, thereby causing the movable iron core to perform forward pushing or rear pulling operation. The electromagnetic switch 32 itself is prior art, and will not be described here. The output end of the electromagnetic switch 32 penetrates through the support plate 22 and faces the baffle 23. Thus, when the electromagnetic switch 32 is energized, the movable iron core inside the electromagnetic switch 32 pushes the baffle 23 out, so that the baffle 23 falls on the material channel 21 and is hung by the iron wire 25, thereby intercepting the defective product.

[0027] The detection rod 33 is L-shaped, which is composed of a transmission end 331 and a detection end 332. The length of the transmission end 331 is greater than that of the detection end 332. The end of the transmission end 331 away from the detection end 332 is connected with the Y-axis support rod 313, and the detection end 332 is located directly above the movable tooth plate 12 and the fixed tooth plate 13.

[0028] The fixed tooth plate 13, the detection rod 33, a power supply 34, and an intermediate relay 35 are connected in series, and a circuit is formed between the fixed tooth plate 13 and the detection rod 33. The voltage of the power supply 34 is 8-24V. The intermediate relay 35 is electrically connected with the electromagnetic switch 32, and the intermediate relay 35 is electrically connected with the control console of the screw threading machine. Thus, when the screw floats during threading, that is, the threading part of the screw is defective, the detection end 332 on the detection rod 33 contacts the defective product. Since the screw is made of iron, it has conductivity, thereby forming a path for the series circuit. The intermediate relay 35 controls the electromagnetic switch 32 to push out the baffle 23, so as to intercept the defective product, and the intermediate relay 35 controls the screw threading machine to stop operation, and the series circuit is disconnected again, so as to avoid the equipment being electrified, so as to wait for the operator to take away the defective product, and reset the baffle 23, so as to detect the next floating screw.

[0029] Compared with the prior art, the screw hobbing up floating detection device provided by the utility model forms a circuit by connecting the fixed tooth plate 13, the detection rod 33, the power supply 34 and the intermediate relay 35 in series, forms a break between the fixed tooth plate 13 and the detection rod 33, so that when the screw is floating during hobbing, the detection end 332 on the detection rod 33 is in contact with the defective product, so that the series circuit forms a passage, the intermediate relay 35 controls the electromagnetic switch 32 to work to push out the baffle 23, so as to intercept the defective product, at the same time, the screw hobbing machine stops working in order to wait for the operator to take away the defective product, and the baffle 23 is reset in order to detect the next floating screw, the detection mode is convenient and efficient, the defective product can be effectively prevented from falling into the receiving box, and the production quality of the screw is improved. And the height of the detection rod 33 is changed by changing the position of the adjusting block 312 on the X-axis support rod 311, so that the detection specification of different types of screws is adjusted, and the applicability of the device is improved.

[0030] The above is only the preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement in the spirit of the utility model is covered in the claim scope of the utility model.
