Description

Technical Field

[0001] The present invention relates to the technical field of screw processing, in particular to the technical field of a thread rolling machine for screw production and processing. Background Art

[0002] As a key component in the mechanical field, screws are extremely widely used. In mechanical manufacturing, screws are an important means of connecting components and can tightly connect two or more objects, such as various components like steel beams and plates.

[0003] Currently, during the screw processing, a thread rolling machine is required to perform operations such as thread rolling, straight thread rolling, and inclined thread rolling on the screw, so that the surface of the screw is processed into a thread shape. However, when the existing thread rolling machine processes screws, workers need to manually feed the materials. This feeding method is very troublesome and has certain potential safety hazards.

[0004] To solve the problems raised in the above technology, for example, the patent application No. CN202221661500.6 discloses a screw thread rolling machine, which includes a thread rolling machine main body. The thread rolling machine main body includes two thread rolling wheels. An inlet plate is installed at the feeding end of the thread rolling machine main body. A limiting block is installed on one side of the inlet plate close to the thread rolling wheels. An arc-shaped groove is opened on the upper surface of the limiting block. A feeding push rod is provided on the side of the inlet plate far from the thread rolling wheels. The feeding push rod is driven by a driving mechanism, and the driving mechanism is a linear motor. An installation frame is arranged on the rear side of the inlet plate, and a linear motor is installed on the installation frame. A connecting bracket is provided on the mover of the linear motor. One end of the feeding push rod is fixed on the connecting bracket, and the other end is arranged towards the thread rolling wheels. The screw is automatically fed by the feeding push rod. When it is pushed to the specified position, the limiting block will block the countersunk head, so that the feeding push rod does not continue to push the screw; after the thread rolling is completed, the screw will be discharged under the attraction of the electromagnet. Workers only need to remove the processed screw after the electromagnet is powered off, which is very convenient. However, this device still has the following defects: In the above device, the thread rolling wheels cannot move, so the thread rolling processing of screws with different sizes cannot be carried out, and only screws of the same size can be processed, resulting in low processing efficiency and poor practicability. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the existing technology and propose a thread rolling machine for screw production and processing, which can drive the first thread rolling mechanism to move, thereby adjusting the distance between the two thread rolling wheels, so as to realize the processing of screws with different sizes.

[0006] To achieve the above object, the present invention provides a thread rolling machine for screw production and processing, which includes a base, a first thread rolling mechanism, a second thread rolling mechanism, a groove, a threaded rod, a moving block, a driving mechanism, a support plate, a driving motor, a driving gear, a driven gear, a sliding assembly, a positioning structure and a pushing mechanism. A first thread rolling mechanism and a second thread rolling mechanism are arranged on one side above the base. A groove is formed in the base and below the first thread rolling mechanism. A threaded rod is rotatably arranged in the groove. A moving block is threadedly connected to the outer wall of the threaded rod. The upper part of the moving block is connected to the first thread rolling mechanism through a support rod. One end of the threaded rod penetrates through the side wall of the base and is connected to a driving mechanism. The driving mechanism includes a support plate, a driving motor, a driving gear and a driven gear. The support plate is fixedly installed on the side wall of the base. A driving motor is installed above the support plate. A driving gear is rotatably arranged on the outer wall of the output shaft of the driving motor. The driven gear is rotatably arranged on the outer wall of one end of the threaded rod. The driving gear is meshed with the driven gear. A sliding assembly is arranged above the base. Two positioning structures are arranged on the sliding assembly. A pushing mechanism is further arranged above the base.

[0007] Preferably, both the first thread rolling mechanism and the second thread rolling mechanism are composed of a vertical plate, a horizontal plate, a rotating motor and a thread rolling wheel. One of the vertical plates is fixedly installed on the base. The lower part of the other vertical plate is connected to the support rod on the moving block. The horizontal plate is installed on the side wall of the vertical plate. A rotating motor is installed on the horizontal plate. The output shaft of the rotating motor penetrates through the side wall of the vertical plate and is rotatably connected to a thread rolling wheel.

[0008] Preferably, the sliding assembly includes a guide rail, a sliding block and a motor. The guide rail is horizontally arranged on the base. Two sliding blocks are slidably matched on the guide rail. The upper parts of the two sliding blocks are respectively connected to the two positioning structures through support rods. Two motors are also assembled on the guide rail. The two motors are respectively electrically connected to the two sliding blocks. The sliding blocks are driven by the motors to approach or move away from each other on the guide rail.

[0009] Preferably, the positioning structure includes a first positioning plate and a second positioning plate. The lower part of the first positioning plate is connected to the support rod on the sliding block. The second positioning plate is detachably installed on the inner side surface of the first positioning plate through bolts.

[0010] Preferably, both the first positioning plate and the second positioning plate are in a semi-circular structure. The two first positioning plates are arranged symmetrically left and right. The other two second positioning plates are also arranged symmetrically left and right.

[0011] Preferably, the size of the first positioning plate is larger than that of the second positioning plate. The first positioning plate is used to position the screw with a larger size, and the second positioning plate is used to position the screw with a smaller size.

[0012] Preferably, the pushing mechanism includes an L-shaped support, a pushing cylinder, a hydraulic rod, and a pushing plate. The L-shaped support is fixedly installed on the other side above the base. A pushing cylinder is installed above the L-shaped support. The output end of the pushing cylinder passes through the side wall of the L-shaped support and is connected to the hydraulic rod. The end of the hydraulic rod is connected to the pushing plate, and the pushing plate is of a circular structure.

[0013] Advantages of the present invention: 1. Through the combined cooperation of the threaded rod, the moving block, and the driving mechanism, the present invention can drive the first thread rolling mechanism to move. By driving the output shaft of the driving motor to rotate, the driving gear is driven to rotate. The driving gear drives the driven gear to rotate, and the driven gear drives the threaded rod to rotate. After the threaded rod rotates, it drives the moving block to move, and then drives the first thread rolling mechanism to move. Thus, the distance between the two thread rolling wheels can be adjusted, and then the thread rolling process can be carried out on screws of different sizes, greatly improving the work efficiency, meeting the use requirements of different scenarios, and having stronger practicability. It solves the problem that the thread rolling wheels cannot move, and thus cannot carry out the thread rolling process on screws of different sizes, and can only process screws of the same size. 2. Through the combined cooperation of the sliding assembly and the positioning structure, the present invention can position screws of different sizes. By driving two sliding blocks on the guide rail to approach or move away from each other by two motors, the distance between the two positioning structures can be adjusted, so as to realize the positioning of screws of different sizes, and then facilitate the thread rolling process of the screws, thereby improving the processing quality.

Detailed implementation manner

[0015] Refer to Figures 1 to 6 , a thread rolling machine for the production and processing of screws according to the present invention includes a base 1, a first thread rolling mechanism 2, a second thread rolling mechanism 3, a groove 4, a threaded rod 5, a moving block 6, a driving mechanism 7, a support plate 71, a driving motor 72, a driving gear 73, a driven gear 74, a sliding assembly 8, a positioning structure 9, and a pushing mechanism 10. A first thread rolling mechanism 2 and a second thread rolling mechanism 3 are provided on one side above the base 1. A groove 4 is opened on the base 1 and below the first thread rolling mechanism 2. A threaded rod 5 is rotatably provided in the groove 4. A moving block 6 is threadedly connected to the outer wall of the threaded rod 5. The upper part of the moving block 6 is connected to the first thread rolling mechanism 2 through a support rod. One end of the threaded rod 5 penetrates through the side wall of the base 1 and is connected to a driving mechanism 7; the driving mechanism 7 includes a support plate 71, a driving motor 72, a driving gear 73, and a driven gear 74. The support plate 71 is fixedly installed on the side wall of the base 1. A driving motor 72 is installed above the support plate 71. A driving gear 73 is rotatably provided on the outer wall of the output shaft of the driving motor 72. A driven gear 74 is rotatably provided on the outer wall of one end of the threaded rod 5. The driving gear 73 is meshed and connected to the driven gear 74; a sliding assembly 8 is provided above the base 1, and two positioning structures 9 are provided on the sliding assembly 8; a pushing mechanism 10 is further provided above the base 1. The input end of the driving motor 72 is connected to an external power source. When the driving motor 72 drives the output shaft to rotate, it further drives the driving gear 73 to rotate. The driving gear 73 drives the driven gear 74 to rotate. The driven gear 74 drives the threaded rod 5 to rotate, so that the threaded rod 5 drives the moving block 6 to move after rotation, and further drives the first thread rolling mechanism 2 to move, so as to be able to adjust the distance between the two thread rolling wheels 104, and further perform thread rolling processing on screws of different sizes.

[0016] Refer to Figure 2, both the first thread rolling mechanism 2 and the second thread rolling mechanism 3 are composed of a vertical plate 101, a horizontal plate 102, a rotating motor 103 and a thread rolling wheel 104. One of the vertical plates 101 is fixedly installed on the base 1, and the lower part of the other vertical plate 101 is connected to the support rod on the moving block 6. The horizontal plate 102 is installed on the side wall of the vertical plate 101. A rotating motor 103 is installed on the horizontal plate 102. The output shaft of the rotating motor 103 passes through the side wall of the vertical plate 101 and is rotatably connected to a thread rolling wheel 104. The thread rolling wheel 104 is provided with spiral threads. The input end of the rotating motor 103 is connected to an external power source. After the rotating motor 103 drives the thread rolling wheel 104 to rotate, under the rotational extrusion of the two thread rolling wheels 104, threads corresponding to the thread rolling wheel 104 are formed on the periphery of the screw.

[0017] Refer to Figure 3 , the sliding assembly 8 includes a guide rail 81, a sliding block 82 and a motor 83. The guide rail 81 is horizontally arranged on the base 1. Two sliding blocks 82 are slidably engaged with the guide rail 81. The upper parts of the two sliding blocks 82 are respectively connected to the two positioning structures 9 through support rods. Two motors 83 are also assembled on the guide rail 81. The two motors 83 are respectively electrically connected to the two sliding blocks 82. The input end of the motor 83 is connected to an external power source. By driving the sliding blocks 82 to approach or move away from each other on the guide rail 81 by the motor 83, and by driving the two sliding blocks 82 to approach or move away from each other on the guide rail 81 by the two motors 83, the distance between the two positioning structures 9 can be adjusted, thereby realizing the positioning of screws of different sizes.

[0018] Refer to Figure 4 , the positioning structure 9 includes a first positioning plate 91 and a second positioning plate 92. The lower part of the first positioning plate 91 is connected to the support rod on the sliding block 82. The second positioning plate 92 is detachably installed on the inner side surface of the first positioning plate 91 through bolts. By detachably installing the second positioning plate 92 on the first positioning plate 91, when it is necessary to process a screw with a larger size, the worker screws out the bolts with tools and removes the second positioning plate 92 from the first positioning plate 91, so as to position the screw with a larger size through the first positioning plate 91.

[0019] Refer to Figure 4 , both the first positioning plate 91 and the second positioning plate 92 are in a semi-circular structure. The two first positioning plates 91 are arranged symmetrically left and right, and the other two second positioning plates 92 are also arranged symmetrically left and right. By arranging the first positioning plate 91 and the second positioning plate 92 symmetrically, the positioning plate can accurately position the screw, thereby improving the stability during processing.

[0020] Refer to Figure 4, the size of the first positioning plate 91 is larger than that of the second positioning plate 92. The first positioning plate 91 is used to position the screw with a larger size, and the second positioning plate 92 is used to position the screw with a smaller size. By making the size of the first positioning plate 91 larger than that of the second positioning plate 92, the first positioning plate 91 can position the screw with a larger size, while the second positioning plate 92 can position the screw with a smaller size.

[0021] Refer to Figure 5 , the pushing mechanism 10 includes an L-shaped support 1011, a pushing cylinder 1022, a hydraulic rod 1033 and a pushing plate 1044. The L-shaped support 1011 is fixedly installed on the other side above the base 1. A pushing cylinder 1022 is installed above the L-shaped support 1011. The output end of the pushing cylinder 1022 penetrates the side wall of the L-shaped support 1011 and is connected to a hydraulic rod 1033. The end of the hydraulic rod 1033 is connected to a pushing plate 1044. The pushing plate 1044 is of a circular structure. The input end of the pushing cylinder 1022 is connected to an external power supply. By driving the hydraulic rod 1033 to move through the pushing cylinder 1022, the hydraulic rod 1033 drives the pushing plate 1044 to move, so that the pushing plate 1044 pushes the screw between the two rolling dies 104, so that the screw can enter between the two rolling dies 104 for thread rolling work.

[0022] Working process of the present invention: During the working process of a screw production and processing thread rolling machine of the present invention, first, the distance between the two rolling dies 104 is adjusted according to the size of the screw to be processed, so as to facilitate subsequent thread rolling processing. Secondly, the screw is placed between the two positioning structures 9, and the motor 83 is driven to drive the two sliding blocks 82 to approach each other on the guide rail 81 until the two positioning plates enclose the outside of the screw. After the screw is positioned, the pushing cylinder 1022 drives the hydraulic rod 1033 to move, so that the hydraulic rod 1033 drives the pushing plate 1044 to move, so that the pushing plate 1044 pushes the screw between the two rolling dies 104, so that the screw can enter between the two rolling dies 104 for thread rolling work.

[0023] The control mode of the present invention is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present invention is mainly used to protect mechanical devices, so the control mode and wiring layout of the present invention will not be explained in detail.
