Description

Technical Field

[0002] The thread rolling machine is a professional equipment for producing screws. The main principle of the thread rolling machine is to use a movable thread rolling plate in conjunction with a fixed thread rolling plate. When the movable thread rolling plate moves, the screw blank is squeezed to form screws on its surface. The movable thread rolling plate and the fixed thread rolling plate are respectively provided with bevel teeth on the inner side. The specifications of the bevel teeth are determined according to the thread rolling requirements. As the service cycle increases, the thread rolling plate needs to be replaced, otherwise the screw precision will be low. At the same time, it is easy to cause excess material at the tip of the pointed screw to fail to be accurately removed when threading the pointed screw.

[0042] like Figure 1 and Figures 4 to 6As shown, the detection connection part 1 also includes a rubber pad 103 fixedly mounted on the top of the mounting block 101; two positioning bolts 104 are inserted into the mounting block 101; the two positioning bolts 104 pass through the mounting block 101 respectively; the two positioning bolts 104 are respectively used to be threadedly connected to the ends of the fixed thread rolling plate of the thread rolling machine; an alarm light 105 is fixedly installed on the mounting block 101; the helical tooth broken tail detection part 2 includes a height adjustment block 201 slidably mounted in a slide groove on the mounting block 101; a lifting screw rod 202 is threadedly connected to the height adjustment block 201; the lifting screw rod 202 is rotatably mounted on the mounting block 101; the bottom of the lifting screw rod 202 is a hexagonal block; the interior of the height adjustment block 201 is a cavity structure; the height adjustment block 201 A micro switch 203 is fixedly installed in the cavity, and the micro switch 203 is electrically connected to the alarm light 105; a rotating mounting shaft 204 is fixedly installed in the cavity of the height adjustment block 201; an anti-accidental touch spring 205 is fixedly installed in the cavity of the height adjustment block 201; the anti-accidental touch spring 205 is a "V"-shaped structure; the pointed contact member 3 includes a lifting column 301 slidably installed on the height adjustment block 201; an arc-shaped plate 302 is fixedly installed on the top of the lifting column 301; the arc-shaped plate 302 is an arc structure; a rotating toggle plate 303 is rotatably installed at the bottom of the lifting column 301; a sliding groove 3031 is provided on the rotating toggle plate 303; the rotating mounting shaft 204 slides in the sliding groove 3031; the bottom of the rotating toggle plate 303 is connected At the end of the anti-accidental touch spring piece 205; the rotating toggle plate 303 is squeezed and fitted with the top of the micro switch 203; the anti-accidental touch spring piece 205 is used to elastically support the rotating toggle plate 303, and adopts a pointed contact member 3. It utilizes the mobile thread rolling method adopted by the thread rolling machine and can be directly installed on the side of the fixed thread rolling plate, so as to realize the detection of the end of the pointed screw. Once the pointed screw cannot be rubbed off the tail material of the screw tip due to factors such as the wear of the oblique teeth on the thread rolling plate during thread rolling, it can be squeezed to the lifting column 301, and the oblique tooth broken tail detection member 2 can quickly detect and control the alarm, which is convenient for the staff to find out in time. The structure is more reasonable, avoiding the early stage of manual detection leading to the batch production of a large number of defective screws causing economic losses. The tail detection part 2 can adjust the detection height and can be adjusted according to the requirements of thread rolling specifications. The structure is more reasonable. If there is tail material at the tip of the bottom of the screw and it is not cut off by the inner thread rolling plate, the screw length exceeds the standard and will squeeze the curved plate 302. At this time, the curved plate 302 drives the lifting column 301 to descend, and drives the rotating toggle plate 303 to rotate. The sliding groove 3031 on the rotating toggle plate 303 is on the left side. At this time, when the left end of the rotating toggle plate 303 is moved by downward pressure, the upward movement of the right end of the rotating toggle plate 303 is greater, which can increase the detection sensitivity. When the rotating toggle plate 303 moves upward, the squeezing of the micro switch 203 can be released, and the alarm light 105 can be controlled to light up and alarm, prompting the staff to stop the machine for maintenance.

[0043] like Figure 4 、 Figure 7 and Figure 8 As shown, the paddle cleaning member 4 includes a paddle mounting plate 401 fixedly mounted on the mounting block 101; an elastic paddle 402 is fixedly mounted on the paddle mounting plate 401; the elastic paddle 402 is an elastic thin sheet structure; the rotating brush wiping member 5 includes a steel brush roller 501 rotatably mounted on the detection probe plate 102; the steel brush roller 501 is provided with steel bristles on the outside; the two ends of the steel brush roller 501 pass through the detection probe plate 102 respectively; a roller 502 is fixedly mounted on the bottom end of the steel brush roller 501; a rubber ring is sleeved on the outside of the roller 502; the rubber ring sleeved on the outside of the roller 502 is coated with a layer; the roller 502 is used to fit the inner side of the movable thread rolling plate; the front of the elastic paddle 402 The end is located between the steel bristles provided on the outside of the steel brush roller 501; the front end of the elastic paddle 402 is used to poke the steel bristles provided on the outside of the steel brush roller 501, and the rotating brush wiping member 5 can be used to automatically roll and sweep the movable thread rolling plate during the movement of the movable thread rolling plate, thereby removing iron filings and impurities that may exist on its surface, thereby improving the cleaning efficiency of this structure. At the same time, in conjunction with the paddle cleaning member 4, the rotating brush wiping member 5 can be cleaned to avoid the problem of long-term brushing of the steel bristles on the rotating brush wiping member 5, resulting in excessive iron filings and impurities on the surface, thereby ensuring the accuracy of the bevel tooth detection of the thread rolling plate, improving the detection accuracy, and avoiding misjudgment of detection.

[0044] like Figures 9 to 11As shown, the deviation display member 6 includes a detection sleeve 601 fixedly mounted on the detection probe plate 102; a detection slider 602 is slidably sleeved inside the detection sleeve 601; a groove is provided on the side of the detection slider 602; a digital pressure sensor 603 is fixedly mounted on the detection sleeve 601, and a PSD-4 digital pressure sensor 603 can be used; the digital pressure sensor 603 passes through the detection sleeve 601; the detection end of the digital pressure sensor 603 is attached to the detection slider 602; the digital pressure sensor 603 is used to detect the wear of the bevel teeth of the movable thread rolling plate; the deviation display member 6 also includes a tension spring 604 sleeved inside the detection sleeve 601 ; The tension spring 604 is connected between the detection slider 602 and the detection probe plate 102; the tension spring 604 is used to pull the detection slider 602 to the end of the multi-directional detection member 7; the multi-directional detection member 7 includes an adapter ball head 701 sleeved inside the spherical groove 1021; a sliding column 702 is slidably mounted on the adapter ball head 701; the end of the sliding column 702 is an arc-shaped structure; the end of the sliding column 702 is attached to the groove on the side of the detection slider 602; the adapter ball head 701 is used to rotate in the spherical groove 1021; a limit ring 7021 is sleeved on the sliding column 702; the limit ring 7021 is located on the limit sliding column 702; the multi-directional detection member 7 also includes a fixed mounting on the sliding column The fitting disk 703 at the other end of 702; the fitting disk 703 is used to fit the bevel teeth of the movable thread rolling plate; the outer ring of the fitting disk 703 is a bevel structure; a fitting extrusion spring 704 is sleeved on the sliding column 702; the fitting extrusion spring 704 is connected between the detection probe plate 102 and the fitting disk 703, and the multi-directional detection part 7 is used to detect the wear of the bevel teeth in real time, which can avoid the problem that the screw thread rolling depth does not meet the standard and affects the pitch. This structure can improve the detection quality. At the same time, the use of the adapter ball head 701 can realize the adaptation detection work of multiple directions and angles. While performing wear detection, it can timely detect when there is deviation in the front, back, left and right directions. The comprehensiveness of the detection is guaranteed. The deviation display part 6 can use pressure detection to observe the flatness in real time, which is more intuitive and reliable, and can enable the staff to quickly deal with the problem after discovering it. Once the movable thread rolling plate is skewed, the bonding disk 703 is still bonded to the movable thread rolling plate, and the sliding column 702 will swing at an angle. At this time, the sliding column 702 will squeeze the groove on the side of the detection slider 602. At this time, the detection slider 602 will move backward due to the squeezing, and will not be affected by the swing direction of the sliding column 702, that is, the direction in which the movable thread rolling plate is skewed. The detection slider 602 can be controlled to move backward, and it can be displayed through the digital pressure sensor 603.

[0045] The working principle provided by the present invention is that, first, the positioning bolt 104 is threadedly connected to the end of the fixed thread rolling plate of the thread rolling machine, and the rotating lifting screw rod 202 can drive the height adjustment block 201 to move upward to adjust the alarm height of the arc plate 302. As the movable thread rolling plate is driven to move back and forth to roll the thread, after the screw blank is finished being rolled, the screw will be driven to roll to the side of the rubber pad 103 under the fitting drive of the movable thread rolling plate. At this time, if there is tail material at the tip of the bottom of the screw and it is not cut off by the inner thread rolling plate, the screw length exceeds the standard and will squeeze the arc plate 302. At this time, the arc plate 302 drives the lifting column 301 to descend, and drives the rotating toggle plate 303 to rotate. The sliding groove 3031 on the rotating toggle plate 303 is on the left side.

[0046] At this time, when the left end of the rotating toggle plate 303 is subjected to downward pressure, the right end of the rotating toggle plate 303 moves upward with a larger amplitude, which can increase the detection sensitivity. When the rotating toggle plate 303 moves upward, the squeezing micro switch 203 can be released, and the alarm light 105 can be controlled to light up and alert the staff that the machine needs to be stopped for maintenance. When the movable thread-grinding plate moves, the side without bevel teeth on the inside will squeeze the fitting roller 502, and use the friction force to drive the steel brush roller 501 to rotate, and in the process, the movable thread-grinding plate will also be brushed. As the steel brush roller 501 rotates, the elastic paddle 402 can elastically poke the bristles of the steel brush roller 501 to assist in cleaning; when the movable thread rolling plate moves, it cooperates with the inclined surface structure of the outer ring of the bonding disk 703, and then slides to the bonding disk 703 set for bonding. At this time, under the pull of the tension spring 604, the detection slider 602 squeezes the sliding column 702 inward, and cooperates with the matching ball head 701 to be able to The multi-directional adjustment inside the groove 1021 adapts to the bevel surface of the movable thread rolling plate. At this time, the sliding post 702 can drive the fitting plate 703 to elastically fit the movable thread rolling plate. Once the movable thread rolling plate is skewed, the fitting plate 703 is still fitted on the movable thread rolling plate, and the sliding post 702 will swing at an angle deviation. At this time, the sliding post 702 will squeeze the groove on the side of the detection slider 602. At this time, the detection slider 602 will move backward due to the squeezing, regardless of the swing direction of the sliding post 702, that is, the direction in which the movable thread rolling plate is skewed, the detection slider 602 can be controlled to move backward. By observing the data displayed on the display of the digital pressure sensor 603 in real time, when the bevel teeth of the movable thread rolling plate are worn and thinned as a whole, the fitting plate 703 can be driven to remain fitted on the movable thread rolling plate under the squeezing of the fitting squeezing spring 704. At this time, the detection slider 602 moves inward, and the digital pressure sensor 603 can be displayed to ensure the accuracy and comprehensiveness of the overall detection.
