Background
For the external thread processing of the metal bolt, the prior art is mostly realized by adopting modes of rolling, turning, milling and the like, wherein the rolling is realized by rolling the surface of the bolt by utilizing two rotary thread rollers which are oppositely arranged in a thread rolling machine so as to form threads, and redundant metal waste can not be generated in the thread processing process.
The rolling machine is divided into axial thread rolling and tangential thread rolling, and the difference is that: in the axial thread rolling roller, two thread rollers are fixed to rotate, and a bolt rotates between the two thread rollers to roll; the tangential thread rolling is that one of the thread rollers is fixedly rotated, the other one is non-fixedly rotated, the bolt does not need to rotate and advance, the bolt is only needed to be clung to the thread roller which is fixedly rotated, and then the non-fixedly rotated thread roller approaches the bolt until the bolt is clamped, and then rolling is realized.
In the prior art, for a thread rolling machine for tangential thread rolling, manual placement is adopted when a bolt is placed between two thread rollers, and the two thread rollers rotate to drive the bolt to rotate, so that when the bolt is placed, hands are required to be separated from the bolt in time, otherwise potential safety hazards are easy to generate, and in order to reduce the potential safety hazards, the setting of a protective cover is also increased in the prior art, for example, the application number is CN201710761495.3, and the Chinese patent publication number is CN107570646B, and the name is a 'bolt thread rolling machine protective device', and a sensor is disclosed and is used for sensing the closing state of a first protective cover and a second protective cover. When the first protective cover and the second protective cover are not in the respective closed states, or when one of the first protective cover and the second protective cover is opened, the sensor can sense to start the alarm device and stop working through the controller.
In the above patent, by adding the sensor and the first and second shields, the operation safety can be improved to some extent, but in actual operation, there are at least the following drawbacks:
since when one of the first and second shields is opened, the sensor senses the start of the alarm device and stops the operation by the controller, the two screw rollers arranged oppositely are in a stopped rotation state, and when the bolt is placed between the two screw rollers, the first shield or the second shield must be opened, so that the two screw rollers are in a stopped rotation state, and although the safety of an operator can be ensured by placing the bolt between the two screw rollers stopped from rotating, it is well known that: when rolling the bolt, the bolt is the upper half of placing between two screw thread gyro wheels parallel with the screw thread gyro wheel, and can add lubricating oil on two screw thread gyro wheels and bolt in order to reduce the production of heat and keep better lubrication effect moreover, make the friction between bolt and the two screw thread gyro wheels very little, when placing the bolt between stopping pivoted two screw thread gyro wheels earlier, when waiting to start two screw thread gyro wheels rotation, the rotation force of two screw thread gyro wheels can certainly jack up the bolt, make the bolt can't be rolled by two screw thread gyro wheels, it can only realize the effective rolling by two screw thread gyro wheels by increasing stop gear that can prevent the bolt from moving up, but this must after that lead to producing frictional force and increase the wearing and tearing of bolt between bolt and the stop gear. When the two threaded rollers are started to rotate first and then the bolts are placed manually, the hand can have a limiting acting force on the bolts when the bolts are placed, so that the bolts cannot be jacked up upwards under the rotating force of the two threaded rollers when being contacted with the two threaded rollers, the two threaded rollers can roll the outer surfaces of the bolts, rolling threads can be achieved, and potential safety hazards are easily caused. It follows that no solution is found in the prior art, namely: how to ensure that the bolt is effectively rolled by two threaded rollers without additionally increasing a limiting mechanism while reducing the generation of potential safety hazards is a technical problem to be solved.

When the motor 7 is started to drive the gear 8 to rotate, the gear 8 drives the rotating assembly 10 to rotate, the pre-driving arm plate 11 synchronously rotates along with the rotating assembly 10, and when the arm plate 11 rotates to a specific angle, the rotating assembly 10 can be driven to drive the arm plate 11 to perform linear motion along with further rotation of the gear 8. The working principle is as follows: firstly, the driving mechanism adjusts the arm plate 11 to the position of the plug cap 26 away from the two threaded rollers 3, then, the driving mechanism stops running to lock the arm plate 11, the end of the bolt 9 needing to be processed threads is clamped in the plug cap 26 to be fixed, then, the driving mechanism is started again to drive the gear 8 to rotate, the gear 8 drives the rotating assembly 10 to rotate, the rotating assembly 10 firstly rotates the synchronous arm plate 11, the rotating motion of the arm plate 11 drives the plug cap 26 and the bolt 9 to synchronously rotate, when the arm plate 11 rotates to a specific angle, the bolt 9 clamped by the plug cap 26 is positioned above the two threaded rollers 3 and is parallel to the two threaded rollers 3, then, the further rotation of the gear 8 drives the arm plate 11 to linearly move, the linear motion of the arm plate 11 drives the plug cap 26 to synchronously linearly move, the bolt 9 is synchronously linearly moved again, the state parallel to the two threaded rollers 3 is kept to the two threaded rollers 3 at the moment when the bolt 9 is translated to the rolling station, the clamping state of the plug cap 26 to the bolt 9 is kept, when the bolt 9 is translated to the rolling station, the bolts 9 are in contact with the fixed threads 3, the two threaded rollers 3 are pressed against the fixed threads, and the two threaded rollers 9 can be prevented from rotating relatively, and the bolt 9 can be rotated, and the bolt 9 is prevented from being rotated relatively, and the bolt 9 is pressed and rotated, and the bolt 9 is prevented from being rotated, and against the threaded 3.
It can be seen that in this embodiment, by rotationally setting the rotating assembly 10, the rotating assembly 10 is elastically slidably provided with the arm plate 11, one end of the arm plate 11 protruding from the rotating assembly 10 is rotationally provided with the socket cap 26 for clamping the bolt 9, when the bolt 9 is clamped in the socket cap 26, the driving mechanism with the self-locking function stops running, and the socket cap 26 is far away from the two threaded rollers 3, when the rotating assembly 10 is driven to rotate by the driving mechanism with the self-locking function, the arm plate 11 can be driven to sequentially perform rotational movement and linear movement, the rotational movement of the arm plate 11 moves the bolt 9 from a position far away from the threaded rollers 3 to above the two threaded rollers 3 through the socket cap 26 and is parallel to the two threaded rollers 3, and when the bolt 9 is clamped on the socket cap 26, the driving mechanism stops running so that the rotating assembly 10 cannot rotate, and when the socket cap 26 is far away from the two threaded rollers 3 in rotation, therefore the potential safety hazard can be effectively reduced in operation; the linear motion of the arm plate 11 translates the bolt 9 to the rolling station through the plug cap 26 and keeps the clamping state of the plug cap 26 on the bolt 9, so that the bolt 9 cannot be jacked up when the bolt 9 contacts the rotating two threaded rollers 3, and the bolt 9 can be effectively rolled by the two threaded rollers 3 at the rolling station;

The meshing teeth 1201 are fixedly arranged on the outer peripheral surface of the outer rotating wheel 12, and since the outer rotating wheel 12 is elastically sleeved on the inner rotating wheel 13, elastic rotation resistance is provided between the outer rotating wheel 12 and the inner rotating wheel 13, and the minimum value of the elastic rotation resistance of the outer rotating wheel 12 relative to the inner rotating wheel 13 is larger than the rotation resistance of the inner rotating wheel 13 during rotation, when the gear 8 rotates, the outer rotating wheel 12 and the inner rotating wheel 13 can be driven to synchronously rotate through the meshing teeth 1201, at the moment, the outer rotating wheel 12 cannot overcome the elastic rotation resistance between the outer rotating wheel and the inner rotating wheel 13, and the arm plate 11 is elastically and slidably inserted with the inner rotating wheel 13 in the radial direction of the inner rotating wheel 13, so that the rotation of the inner rotating wheel 13 drives the arm plate 11 to synchronously rotate the bolt 9 to a position parallel to the two threaded rollers 3.

Specifically, the stopper 1303 is fixedly installed on the outer side surface of the cylinder 1301, when the arm plate 11 rotates to a position where the bolt 9 is parallel to the two threaded rollers 3, the stopper 1303 is abutted against the stopper, at this time, the inner rotating wheel 13 stops rotating, and then the arm plate 11 also stops rotating, along with further rotation of the gear 8, the outer rotating wheel 12 is driven to continuously rotate against elastic rotation resistance, so that the outer rotating wheel 12 rotates around the inner rotating wheel 13 to enable the outer rotating wheel 12 to rotate relative to the inner rotating wheel 13, based on the setting of the linkage mechanism, when the outer rotating wheel 12 rotates relative to the inner rotating wheel 13, the rotating force of the outer rotating wheel 12 can drive the arm plate 11 to do elastic linear motion towards the two threaded rollers 3, the arm plate 11 drives the bolt 9 to translate towards the two threaded rollers 3 until the bolt 9 abuts against the fixed rotating threaded rollers 3 to the rolling station, then the driving mechanism is closed to lock the arm plate 11, the arm plate 11 is locked, and then the bolt 9 is locked at the rolling station, when the non-fixed rotating threaded rollers 3 abut against the bolt 9, the bolt 9 cannot lift under the limiting action of the arm plate 11, so that the bolt 9 can not lift up under the limiting action of the rolling station, and the effective rolling of the bolt 9 can be ensured.
Wherein, the inside of outer rotor 12 is provided with the inner chamber, and outer rotor 12 includes detachable first preceding curb plate 1205, and first preceding curb plate 1205 passes through screwed connection with outer rotor 12, is convenient for the installation of part through setting up detachable first preceding curb plate 1205. The side plate opposite to the first front side plate 1205 on the outer rotating wheel 12 is the rear side plate of the outer rotating wheel 12, the inner side surface of the rear side plate of the outer rotating wheel 12 and the inner side surface of the first front side plate 1205 are respectively connected with the outer side surface of the inner rotating wheel 13 through a first bearing 14 in a rotating way so as to reduce the rotating friction force between the outer rotating wheel 12 and the inner rotating wheel 13, and meanwhile, a bearing can be arranged between the cylinder 1301 and the pin shaft so as to reduce the rotating friction force of the inner rotating wheel 13.
The inner rotating wheel 13 comprises a detachable second front side plate 1302, the second front side plate 1302 is connected with the inner rotating wheel 13 through screws, a guide plate 15 is fixedly arranged on the opposite surfaces of the rear side plate of the inner rotating wheel 13 and the second front side plate 1302, a guide groove 1102 is formed in the front side surface and the rear side surface of the arm plate 11, the two guide plates 15 are in one-to-one sliding connection with the two guide grooves 1102 so that the arm plate 11 can slide along the radial direction of the inner rotating wheel 13, and the arm plate 11 cannot rotate relative to the inner rotating wheel 13 under the limiting action of the guide plates 15. Furthermore, the inner rotating wheel 13 is provided with an avoidance jack 1304, and the arm plate 11 is in sliding connection with the avoidance jack 1304, so that the sliding stability of the arm plate 11 is further improved, and the stability of the arm plate 11 and the inner rotating wheel 13 in relative rotation is prevented. The arm plate 11 passes through the avoidance hole 1304 and then passes through the avoidance hole 1202, and the arc length of the avoidance hole 1202 is greater than that of the avoidance hole 1304 so that the arm plate 11 can rotate relative to the outer rotating wheel 12, namely: when the outer rotating wheel 12 and the inner rotating wheel 13 rotate relatively to drive the arm plate 11 to move linearly, the arm plate 11 does not hinder the rotation of the outer rotating wheel 12.
The inner cavity of the outer rotating wheel 12 is fixedly provided with a first fixing plate 17, the outer wall of the inner rotating wheel 13 is fixedly provided with a second fixing plate 18, an arc rod 19 with a first pressure spring 20 sleeved outside is arranged between the first fixing plate 17 and the second fixing plate 18, one end of the arc rod 19 is fixedly connected with the first fixing plate 17, the other end of the arc rod 19 penetrates through the first fixing plate 17 in a sliding mode and then is connected with a locking block 22 in butt fit with the first fixing plate 17, and the arc rod 19 and the outer rotating wheel 12 are coaxial. Specifically, the locking block 22 is used for limiting the arc rod 19, so that the arc rod 19 cannot be separated from the first fixing plate 17, the first pressure spring 20 is always in a compressed state, the side surface of the locking block 22 is pressed and abutted against the side surface of the first fixing plate 17 under the action of compression elastic force of the first pressure spring 20, and meanwhile, the rotation resistance when the outer rotating wheel 12 rotates around the inner rotating wheel 13 is larger than the rotation resistance of the cylinder 1301, so that the outer rotating wheel 12 can drive the inner rotating wheel 13 to rotate through the first pressure spring 20 before the limiting block 1303 abuts against the stop block. The first compression spring 20 is slidably sleeved with a gasket 21, and the gasket 21 is located between the first compression spring 20 and the first fixing plate 17 and used for limiting the end portion of the first compression spring 20. The working principle is as follows: when the gear 8 rotates to drive the outer rotating wheel 12 to rotate, the outer rotating wheel 12 drives the inner rotating wheel 13 to synchronously rotate towards the direction of the threaded roller 3 under the elastic supporting action of the first pressure spring 20 until the limiting block 1303 is abutted with the stop block, then the inner rotating wheel 13 stops rotating, the outer rotating wheel 12 drives the first fixed plate 17 to continue rotating, the arc rod 19 does not rotate because the inner rotating wheel 13 does not rotate, and the gasket 21 is driven to squeeze the first pressure spring 20 to continuously compress against the elastic force of the first pressure spring 20 in the rotating process of the first fixed plate 17, so that the relative rotation of the outer rotating wheel 12 and the inner rotating wheel 13 is realized; when the gear 8 rotates reversely, the elastic force of the first pressure spring 20 is released immediately to drive the first fixing plate 17 to rotate towards the locking block 22 until the first fixing plate is in re-abutting connection with the locking block 22 to reset the outer rotating wheel 12, and then the rotation of the outer rotating wheel 12 drives the inner rotating wheel 13 to synchronously rotate in a direction away from the threaded roller 3 through the abutting connection effect of the first fixing plate 17 and the locking block 22.
In this embodiment, the linkage mechanism includes an arc plate 23 fixedly connected with the outer rotating wheel 12 and a transmission gear 25 rotatably disposed on the inner rotating wheel 13, the transmission gear 25 is located between the outer wall of the arc plate 23 and the arm plate 11, the outer wall of the arc plate 23 is provided with arc teeth 2301, one side of the arm plate 11 close to the transmission gear 25 is provided with tooth grooves 1103, and the transmission gear 25 is meshed with the arc teeth 2301 and the tooth grooves 1103. Specifically, the arc plate 23 is coaxial with the outer rotating wheel 12, one end of the arc plate 23 is fixedly connected with the first fixed plate 17, the other end is a free end, a pair of support plates 24 are fixedly arranged on the outer wall of the inner rotating wheel 13, the transmission gear 25 is rotatably arranged between the pair of support plates 24, when the outer rotating wheel 12 rotates around the inner rotating wheel 13, the arc plate 23 is driven to synchronously rotate, the transmission gear 25 and the arm plate 11 cannot rotate around the axis of the inner rotating wheel 13 due to the fact that the inner rotating wheel 13 does not rotate, under the meshing effect, the rotation of the arc plate 23 drives the transmission gear 25 to rotate, and the rotation of the transmission gear 25 drives the arm plate 11 to linearly slide, so that the bolt 9 is driven to translate to a rolling station towards the threaded roller 3. Similarly, when the gear 8 rotates reversely to release the elastic force of the first pressure spring 20 to drive the first fixing plate 17 to rotate towards the locking block 22, the first fixing plate 17 drives the arc plate 23 to rotate synchronously, the rotation of the arc plate 23 drives the transmission gear 25 to rotate reversely, and the transmission gear 25 drives the arm plate 11 to slide linearly inwards of the inner rotating wheel 13 to separate the bolt 9 from the rolling station.
The arm plate 11 is provided with an elongated hole 1101, in an initial state, a free end of the arc plate 23 is inserted into the elongated hole 1101, and an outer wall of the arc plate 23 is slidably abutted with an outer side surface of the elongated hole 1101 to limit the arm plate 11. Specifically, the second fixing plate 18 is provided with an opening into which the arc plate 23 is inserted, and the free end of the arc plate 23 passes through the second fixing plate 18 through the opening in the second fixing plate 18 and then enters the elongated hole 1101, and the outer wall of the arc plate 23 abuts against the outer side surface of the elongated hole 1101, so that the arm plate 11 is limited in a straight line.
Further, the extension spring 16 is fixedly installed at one end of the arm plate 11 far away from the plugging cap 26, one end of the extension spring 16 far away from the arm plate 11 is fixedly connected with the inner wall of the inner rotating wheel 13, and in an initial state, the extension spring 16 is in a stretching state so that the outer wall of the arc plate 23 and the outer side face of the long hole 1101 are elastically extruded, and at the moment, the generated effect is that: under the action of the elastic extrusion of the outer wall of the arc plate 23 and the outer side surface of the elongated hole 1101, the arm plate 11 is specific to the position of the inner rotating wheel 13 in the initial state, and meanwhile, the centrifugal force generated when the inner rotating wheel 13 rotates is far smaller than the deformation elastic force of the tension spring 16, so that under the limiting action of the arc plate 23, when the inner rotating wheel 13 rotates, the arm plate 11 and the inner rotating wheel 13 can be kept relatively fixed all the time, the arm plate 11 is prevented from shaking to improve the stability of the arm plate 11, and the method is another technical effect of the arc plate 23.
The arcuate teeth 2301 do not prevent the relative rotation between the arcuate plate 23 and the arm plate 11, specifically, in an initial state, when the outer side surface of the elongated hole 1101 is abutted to the outer wall of the arcuate teeth 2301, the arcuate teeth 2301 are not in contact with the arm plate 11, a certain distance is kept between the arcuate teeth 2301 and the arm plate 11, when the arm plate 11 is not rotated by the arcuate plate 23, the arcuate plate 23 drives the transmission gear 25 to rotate first, the transmission gear 25 drives the arm plate 11 to slide towards the outside of the inner rotating wheel 13, at this time, the outer side surface of the elongated hole 1101 is separated from the outer wall of the arcuate plate 23, and meanwhile, the arcuate teeth 2301 are continuously approaching the arm plate 11, and when the arcuate teeth 2301 reach the side wall of the arm plate 11, the distance between the outer wall of the arcuate plate 23 and the outer side surface of the elongated hole 1101 is greater than the height of the arcuate teeth 2301 so that the arcuate teeth 2301 can enter the elongated hole 1101, and the arcuate teeth 2301 cannot contact the arm plate 11, and do not prevent the relative rotation between the arcuate plate 23 and the arm plate 11.
Wherein the length of the elongated hole 1101 in the length direction of the arm plate 11 is much greater than the thickness of the arc plate 23 so that the arc plate 23 does not interfere with the linear sliding of the arm plate 11 when the arc plate 23 rotates relative to the arm plate 11.
Further, the hanging block 6 is fixedly installed on the fixing frame 5, and after the bolts 9 finish the thread processing, the arm plate 11 drives the bolts 9 to rotate towards the hanging block 6 to drive the end parts of the bolts 9 to touch the side surfaces of the hanging block 6 so as to separate the bolts 9 from the plug-in caps 26. Specifically, when the screw 9 completes the thread processing, the gear 8 rotates reversely to drive the arm plate 11 to slide linearly in a direction away from the thread roller 3 to drive the screw 9 to separate from the rolling station until the outer side surface of the long hole 1101 is in re-contact with the outer wall of the arc plate 23, at this time, the outer rotating wheel 12 completes resetting, then the outer rotating wheel 12 and the inner rotating wheel 13 synchronously rotate to drive the arm plate 11 and the screw 9 to rotate in a direction away from the thread roller 3, the screw 9 rotates in a direction away from the thread roller 3, namely rotates in a direction towards the hanging block 6 until the end part of the screw 9 is in contact with the side surface of the hanging block 6, and the hanging block 6 pushes the screw 9 out of the plug cap 26 under the action of the rotation force of the screw 9, so that automatic blanking is realized (as shown in fig. 13).
Further, an outlet 1204 is formed in the outer rotating wheel 12, and the bolt 9 after the thread machining is separated from the plug cap 26, enters the inner cavity of the outer rotating wheel 12 through the avoiding port 1202 and slides out of the outlet 1204 to a specific position for collection. Specifically, after the bolt 9 is pushed out from the plugging cap 26, the bolt 9 downwards enters the avoiding opening 1202 under the action of gravity of the bolt 9 and falls into the inner cavity of the outer rotating wheel 12, then slides to the outlet 1204 along the inner wall of the outer rotating wheel 12, finally slides out to a specific position from the outlet 1204, so that the concentrated collection of the bolt 9 after the thread machining is realized, the outer rotating wheel 12 plays a role in guiding the bolt 9 after the blanking, the technical effect of conveniently collecting the bolt 9 after the thread machining in a concentrated manner is generated, and a corresponding guiding structure is omitted. The guard plate 1203 protruding outwards is fixedly arranged at the avoidance port 1202 and used for blocking the bolt 9, so that the bolt 9 can enter the avoidance port 1202.
Therefore, the rotation of the outer rotating wheel 12 plays a role in automatically blanking the bolts 9 after the thread machining and guiding the bolts 9 after the blanking, so that the corresponding structural arrangement is omitted, and the utilization rate of the rotating assembly 10 is improved.
In this embodiment, a circular hole is formed in the arm plate 11, the plugging cap 26 is rotationally plugged into the circular hole through the second bearing 27, a clamping hole 2601 matched with the bolt head of the bolt 9 in shape is formed in the center of the plugging cap 26, so that the bolt head of the bolt 9 is slidingly inserted into the clamping hole 2601 (the bolt head of the bolt 9 is a hexagon), and when the bolt head of the bolt 9 is slidingly inserted into the clamping hole 2601, the plugging cap 26 does not rotate relatively. The inner wall of the holding hole 2601 is provided with a plurality of sliding holes 2602, each sliding hole 2602 is slidably inserted with a top block 28, the bottom of each top block 28 is a hemisphere, a second pressure spring 29 is connected between each top block 28 and each sliding hole 2602, one end of each second pressure spring 29 is fixedly connected with the top of each top block 28, the other end of each second pressure spring 29 is fixedly connected with the inner wall of each sliding hole 2602, in an initial state, the hemispheres at the bottom of each top block 28 protrude out of each sliding hole 2602, when the bolt heads of the bolts 9 are inserted into the holding holes 2601, the hemispheres at the bottom of each top block 28 can be pushed to enable the top block 28 to slide towards the inside of each sliding hole 2602, the sliding of each top block 28 pushes the second pressure spring 29 to compress to generate compression elasticity, and the bottoms of the plurality of top blocks 28 squeeze the bolt heads of the bolts 9 under the compression elasticity of the second pressure springs 29 so as to increase friction force between the bolt heads of the bolts 9 and the holding holes 2601, and accordingly the bolts 9 can be held by the inserting caps 26.
