Description

Technical Field

[0001] The invention belongs to the technical field of gear processing tooling, and in particular relates to a processing tooling for coal mining machine gears. Background Art

[0002] Coal mining machine gear processing tooling is an important equipment to ensure the gear processing accuracy and quality. It can ensure that the coal mining machine gear remains stable during the gear cutting process, thereby ensuring the gear processing accuracy.

[0003] During the processing of coal mining machine gears, the tooling needs to withstand large cutting forces for a long time. As the use time increases, the clamping mechanism of the tooling will fatigue, making the clamping force unable to be effectively transmitted, resulting in insufficient clamping force, which will directly lead to inaccurate gear positioning, making the precision indicators such as the processed gear pitch and coaxiality not meet the requirements. The working environment of the coal mining machine is harsh, and the gears are subjected to huge loads and complex stresses. Therefore, the coal mining machine gear processing tooling needs to ensure higher processing accuracy. For example, the tooth profile accuracy requirements of coal mining machine gears are usually at a higher level, generally requiring 6-7 level accuracy (GB / T10095 standard), which is higher than the accuracy requirements of some traditional mechanical gears. Due to insufficient clamping force, the gear processing accuracy is affected, which will lead to an excessive number of unqualified coal mining machine gears, resulting in a large waste of resources and greatly affecting the processing quality.

[0019] Compared with the existing technology, the beneficial effects of the present invention are:

[0020] 1. Through the setting of the supporting base plate, uniform pressure mechanism, crimping plate, clamping force control mechanism, initial clamping force confirmation mechanism, and gear hardness information feedback adjustment mechanism, a stable clamping force can be provided to the coal mining machine gear, and the clamping points are distributed comprehensively and evenly to ensure the clamping effect, and the size of the initial clamping force can be confirmed based on the material model of the gear to be processed. The greater the hardness of the gear to be processed, the greater the initial clamping force is set, because the greater the hardness of the gear, the stronger the deformation resistance of its material. During the processing, when the cutting tool cuts the gear surface, a cutting force is generated. This cutting force has a tendency to cause the gear to displace. The harder gear material, due to its own rigidity, will not easily deform with the cutting force and fit on the fixture. In order to ensure that the gear does not displace during the processing process, a greater clamping force is required to fix the gear.

[0021] 2. The central positioning reinforcement mechanism can quickly position the gear to be processed to the processing position, and provide a squeezing and clamping force from the inside of the gear to further ensure the positioning stability of the gear. It can also automatically adjust the inner clamping force based on the hardness of the gear to be processed. The greater the gear hardness, the greater the inner clamping force.

[0022] 3. Through the set clamping force compensation control mechanism, the clamping force can be automatically compensated and adjusted during the gear processing to ensure that there is sufficient clamping force to ensure the stable positioning of the gear, thereby ensuring the processing quality of the gear and avoiding fatigue of the clamping mechanism of the fixture over time, which makes the clamping force unable to be effectively transmitted, resulting in insufficient clamping force. The speed of clamping force compensation is automatically adjusted based on the hardness of the gear. The greater the hardness of the gear, the faster the speed of clamping force compensation during processing. Because in the cutting process, the cutting force will fluctuate due to factors such as tool wear and slight changes in cutting parameters, and the gear material with high hardness has higher strength and rigidity. From the perspective of material mechanics, hardness is an indicator of a material's ability to resist local deformation. High hardness means that gears are less likely to undergo elastic or plastic deformation when subjected to external forces. For gears with high hardness, since they are difficult to deform, when the cutting force fluctuates, the gears will hardly adapt to such changes by deforming themselves. If the clamping force cannot compensate for the additional force generated by the cutting force fluctuation in time, the gears will easily undergo slight displacements. Therefore, for gears with high hardness, the impact of such cutting force fluctuations on processing stability is more obvious. Gears with high hardness themselves have strong resistance to displacement. When the cutting force fluctuation causes the clamping force to be insufficient to resist the displacement trend of the gear, more clamping force compensation is required.

[0037] The center positioning reinforcement mechanism 4 is fixedly installed at the center of the upper end of the supporting base plate 1. The center positioning reinforcement mechanism 4 includes a reinforcement tube 41 fixedly installed at the center of the upper end of the supporting base plate 1.

It can automatically compensate and adjust the clamping force during the processing of the gear to ensure that there is sufficient clamping force to ensure the stable positioning of the gear, thereby ensuring the processing quality of the gear.

[0040] The gear hardness information feedback adjustment mechanism 7 is fixedly installed at the lower end of the supporting base plate 1. The gear hardness information feedback adjustment mechanism 7 includes an adjustment shell 71 fixedly installed at the lower end of the supporting base plate 1. A rotating screw 72 is rotatably connected in the adjustment shell 71. A rotating motor 73 for driving the rotating screw 72 to rotate is fixedly installed on the outer wall of the adjustment shell 71. A moving block 74 is threadedly sleeved on the rod wall of the rotating screw 72. A pressing round head 75 is fixedly installed at the lower end of the moving block 74. A plurality of pressing round heads 75 corresponding to the positions of the pressing round heads 75 are equidistantly arranged at the bottom of the inner wall of the adjustment shell 71. An in-position switch 76 is set, and the lower end of the in-position switch 76 is symmetrically fixedly connected to multiple pushing rods 77. The lower ends of the multiple pushing rods 77 extend through the bottom of the adjustment shell 71 and are fixedly connected to the same pushing plate 78. The pushing plate 78 and the adjusting shell 71 are fixedly connected to the opposite side with multiple return springs 79 sleeved on the outside of the pushing rods 77. The lower end of the adjusting shell 71 is fixedly connected to a fixed shaft 710 located on one side of the pushing plate 78. The lower end of the fixed shaft 710 is rotatably connected to a baffle 711, and the surface of the baffle 711 is threadedly connected to a locking bolt 712.

[0041] It also includes: a PLC controller (not shown in the figure), which is electrically connected to the clamping force control mechanism 3, the center positioning reinforcement mechanism 4, the initial clamping force confirmation mechanism 5, the clamping force compensation control mechanism 6, and the gear hardness information feedback adjustment mechanism 7.

[0042] The operating principle of the present invention is now described as follows: the gear to be processed is first placed on the supporting base plate 1, and the center positioning reinforcement mechanism 4 is located in the center hole of the gear. The thrust electromagnetic plate 48 in the center positioning reinforcement mechanism 4 is powered by the PLC controller. The thrust electromagnetic plate 48 is energized to generate the same magnetism as the thrust permanent magnet plate 46, thereby providing a thrust to the force plate 44. The force plate 44 cooperates with the force rod 42 to push the extrusion block 43 outward. The outward movement distances of the multiple extrusion blocks 43 are equal, and the extrusion blocks 43 will contact the inner side of the center hole of the gear, thereby adjusting the processing position of the gear so that the gear is located at the center position of the supporting base plate 1, thereby realizing rapid confirmation of the gear processing position;

[0043] Then, the pressing plate 8 is connected to the supporting base plate 1 by the plug-in action of the pulling rod 23 and the supporting base plate 1. The pressing plate 8 is pressed on the top of the gear to be processed. The pulling rod 23 cooperates with the pressure plate 21 and the multiple pressure columns 22 to evenly distribute the pressure on the pressing plate 8, thereby evenly pressurizing the top of the gear. The cooperation between the supporting base plate 1 and the pressing plate 8 provides a clamping force on the gear, thereby ensuring the placement stability of the gear.

[0044] Before the gear is fully clamped, the corresponding in-position switch 76 in the adjustment housing 71 is found based on the material model of the gear. The outer wall of the adjustment housing 71 is provided with an identification plate so that the material model of the gear corresponds to the in-position switch 76. After finding it, the pushing plate 78 is manually pressed. The pushing plate 78 cooperates with the pushing rod 77 to overcome the elastic force of the return spring 79 to drive the corresponding in-position switch 76 to move upward, and then the baffle 711 is rotated so that the baffle 711 blocks the lower end of the pushing plate 78, thereby limiting the position of the in-position switch 76 and further limiting the baffle 711 by the locking bolt 712.

[0045] The PLC controller controls the rotating motor 73 and the synchronous motor 511 to move together. First, the rotating motor 73 drives the rotating screw 72 to rotate. The threaded connection between the rotating screw 72 and the moving block 74 causes the moving block 74 to drive the pressing round head 75 to move. At the same time, the synchronous motor 511 drives the synchronous screw 510 to rotate. The threaded connection between the synchronous screw 510 and the synchronous seat 512 causes the synchronous seat 512 to cooperate with the magnetic connection component 513 to drive the sliding plate 57 to move downward along the limit slide bar 56 to overcome the elastic force of the push spring 58 until the pressing round head 75 presses on the in-place switch 76. The PLC controller controls the rotating motor 73 and the synchronous motor 511 to stop moving at the same time. Specifically, the harder the gear corresponding to the in-place switch 76 is, the longer it takes for the pressing round head 75 to press on the in-place switch 76. As a result, the synchronous motor 511 will also operate for a longer time, causing the sliding plate 57 to drive the confirmation switch 59 to move downward a greater distance.

[0046] When the gear starts to be clamped, the PLC controller controls the control motor 33 to move, and the control motor 33 drives the control screw 32 to rotate. Through the threaded connection between the control screw 32 and the control plate 34, the control plate 34 cooperates with multiple push-pull rods 35 to push the triangular extrusion block 43 to move in the pressurized port 24 of the rod wall of the pulling rod 23. Because the connection between the triangular pressurizing block 25 and the pressurized port 24 is set to be in inclined contact, as the triangular extrusion block 43 moves, a downward pulling force will be generated on the pulling rod 23, and then a pressurizing force will be provided to the pressing plate 8, thereby gradually increasing the clamping force of the supporting base plate 1 and the pressing plate 8 on the gear. During the movement of the control plate 34, the transmission rack 54 will be driven to move synchronously, and the transmission The meshing action of the movable rack 54 and the transmission gear 53 drives the transmission screw 52 to rotate, and then the transmission plate 55 is gradually moved downward by the threaded connection of the transmission screw 52 and the transmission plate 55. After the transmission plate 55 presses on the confirmation switch 59, the PLC controller controls the control motor 33 to stop, indicating that the initial clamping force on the gear is in place. Because the harder the gear, the greater the distance the confirmation switch 59 moves downward, and the greater the distance between the confirmation switch 59 and the transmission plate 55, the triangular pressure block 25 needs to move a greater distance to make the transmission plate 55 press on the confirmation switch 59, thereby achieving that the greater the hardness of the gear, the greater the initial clamping force on the gear;

[0047] Moreover, as the gear hardness increases, the sliding plate 57 moves downward a greater distance, and the sliding plate 57 drives the feedback conductive contact 63 to slide a greater distance on the feedback resistor rod 61, thereby making the access resistance of the feedback resistor rod 61 smaller. Moreover, the feedback conductive contact 63 and the feedback resistor rod 61 are connected in series to the power supply circuit of the thrust electromagnetic plate 48 in the central positioning reinforcement mechanism 4, thereby gradually increasing the power supply current of the thrust electromagnetic plate 48, causing the extrusion block 43 to generate a greater extrusion force on the inner side of the gear, and simultaneously increasing the clamping force on the inner side of the gear, ensuring the stable placement of the gear.

[0048] And after the confirmation switch 59 is pressed and triggered, the PLC controller controls the circuit conversion device to convert the power supply circuit of the control motor 33 into the second power supply circuit, and the feedback conductive contact 63 and the feedback resistor rod 61 are also connected in series to this second power supply circuit. When the gear processing starts, as the use time increases, the supporting base plate 1 and the crimping plate 8 will become fatigued, so that the clamping force cannot be effectively transmitted, resulting in insufficient clamping force. The PLC controller will control the control motor 33 to continue to operate based on the second power supply circuit, continue to push the triangular pressure block 25 to move, and then compensate for the clamping force between the supporting base plate 1 and the crimping plate 8. The greater the hardness of the gear, the smaller the access resistance of the feedback resistor rod 61, which will increase the power of the control motor 33 and operate at a higher clamping force compensation speed, providing more and faster clamping force compensation for gears with high hardness, ensuring the processing stability of the gear, and better suitable for the processing and use of coal mining machine gears.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
