Description

Technical Field

[0001] The present invention relates to the technical field of gear accessory processing, and particularly relates to a fixture structure for processing bending machine accessories. Background Art

[0002] A bending machine is a machine capable of bending workpieces. The inside of the bending machine contains a large number of gear accessories, which constitute the core part of the transmission system of the bending machine. On the one hand, the gear accessories are responsible for accurately transmitting the rotational motion generated by the power source (such as a motor) to each working component of the bending machine. On the other hand, through the meshing and transmission between gears, the gear accessories can accurately control the movement position and angle of the working components of the bending machine, ensuring the stability and consistency of the bending accuracy.

[0003] Currently, during the processing of gear accessories inside a bending machine, it is necessary to fix the gear shaft through a fixture in order to perform corresponding gear processing operations on the gear blanks on the shaft body. For example, in the patent with the application number: CN202010480442.6, a fixture for gear shaft processing and its gear processing technology are disclosed, which relates to the technical field of gear processing. The key points of its technical solution are: the fixture includes a chuck, and a plurality of jaws are arranged circumferentially on the chuck. The jaws are slidably arranged on the chuck along the radial direction of the chuck. Each jaw is respectively fixed with a clamping seat, and a clamping bar is arranged at a position of the clamping seat facing the axis of the chuck. The length direction of the clamping bar is along the axial direction of the chuck, and the clamping bar is used for clamping at the tooth groove of the gear. In this processing technology, the gear is clamped by the clamping bar, and the position where the clamping bar contacts the gear is located in the tooth groove of the gear, so the clamping of the gear shaft by the clamping seat is very firm. Even if the remaining force of the processed gear is large, there will be no relative rotation between the rotating shaft and the chuck, making the tooth positions of the adjacent gears processed accurately correspond.

[0004] Regarding the above-mentioned currently existing fixtures for processing bending machine gear accessories, most of them are chuck structures, and the clamping seat is a closed circle. This leads to the situation that when it is necessary to change the fixed position of the gear shaft, the gear shaft cannot be directly placed at the required position for fixation. Instead, it is necessary to pass the gear shaft through the hole inside the clamping seat before fixation, and the loosening and clamping operations are relatively cumbersome and troublesome. Moreover, the inner diameter of the through-hole of the existing chuck-structured fixture is small, and it is impossible to achieve through-type fixation of a gear shaft with a larger outer diameter, resulting in poor flexibility and low practicality. Summary of the Invention

[0005] The disclosed embodiment relates to a fixture structure for processing bending machine accessories, which has a fixture assembly. The gear shaft can be directly placed from the top of the fixture assembly into the interior of the fixture assembly for fixation, which is convenient for subsequent processing of the gear shaft and its external gear blank, and can quickly fix the gear shaft in a suitable position. The operation is convenient and flexible, and under the action of a synchronization mechanism and three sets of clamping block mechanisms, automatic centering operation can be achieved to ensure that the axis of the gear shaft is always on the processing axis without deviation. The processing is stable and can meet the processing and fixation requirements of different gear accessories. It is extremely flexible, adaptable and practical.

The two ends of the synchronous main shaft 202 are respectively connected to the bottom of the two linked secondary shafts 203 through two groups of bevel gear sets.

[0032] In the embodiment of the present disclosure, two positioning motors 102 are provided, and the two positioning motors 102 are symmetrically arranged on the side of the fixing seat 101, the side of the positioning seat 201 is provided with a positioning gear ring 2011, and the outer part of the rotating shaft of the positioning motor 102 is provided with a positioning gear 1021, and the gear teeth of the positioning gear 1021 and the positioning gear ring 2011 are meshed for transmission. The design of the two positioning motors 102 makes the positioning gear ring 2011 always mesh with the gear teeth of at least one positioning gear 1021 for transmission, and can stably realize the rotation and positioning action of the positioning seat 201. In use, the positioning gear 1021 of the positioning motor 102 can be meshed with the gear teeth of the positioning gear ring 2011. 11 drives the clamp assembly to rotate and locates the use angle of the positioning seat 201, so that in cooperation with the gear processing equipment, the gear shaft and the gear blank on the shaft body fixed inside the clamp assembly can be processed.

The seat body of the positioning seat 201 is a "C"-shaped design, and the top of the fixed seat 101 is provided with an avoidance notch 1011, and the positioning seat 201 is a "C"-shaped seat body. The use of the avoidance notch 1011 allows the gear shaft to be directly placed from the top of the clamp assembly into the interior of the positioning seat 201 for fixed use, and the gear shaft can be quickly fixed and processed at any position, which is easy to operate and flexible to use.

[0033] In the embodiments of the present disclosure, the outer surface of the rod body of the control rod 302 is provided with threads, and the control rod 302 is screwed into the inside of the action block 303 through the threads on the rod body. During use, the clamping block mechanism 3 can fix gear shafts with different outer diameters inside the positioning seat 201, which facilitates the processing operations of gear shafts and gear blanks of different models, and has extremely strong adaptability. When the control rod 302 is rotated, the control rod 302 can drive the action block 303 to move inside the positioning seat 201 through the threads on the rod body. A linkage groove 3031 with a spiral shape is provided on the outer surface of the action block 303, and a linkage protrusion 3042 is provided inside the linkage block 304. The linkage protrusion 3042 is inserted into the linkage groove 3031. When the positioning seat 201 moves, the linkage groove 3031 can drive the linkage block 304 to rotate by itself through the linkage protrusion 3042. A clamping release rack 3011 is provided on the side surface of the positioning clamp block 301, and a clamping release gear 3041 is provided on the outer surface of the linkage block 304. The teeth of the clamping release gear 3041 and the clamping release rack 3011 are meshed and driven. When the linkage block 304 rotates by itself, the clamping release gear 3041 can drive the positioning clamp block 301 to move radially along the positioning seat 201 through the clamping release rack 3011, thereby changing the clamping inner diameter of the positioning clamp block 301, and thus facilitating the quick clamping and fixing operations of gear shafts and gear blanks of different models and outer diameters, and is convenient and flexible to use.

[0034] In an embodiment of the present disclosure, a linkage gear 3021 is provided at one end of the rod body of the control rod 302, a synchronous gear a 2021 is provided in the middle of the shaft body of the synchronous main shaft 202, and a synchronous gear b 2031 is provided at the top of the linkage secondary shaft 203. The linkage gear 3021 of one set of clamping block mechanisms 3 is in meshing transmission with the teeth of the synchronous gear a 2021, and the linkage gears 3021 of the other two sets of clamping block mechanisms 3 are respectively in meshing transmission with the teeth of the synchronous gears b 2031 of the two linkage secondary shafts 203. During use, under the combined action of the synchronous mechanism and the three sets of clamping block mechanisms 3, the fixture assembly can realize the operation of automatically centering and fixing the gear shaft, ensuring that the rotation axis of the gear shaft and the gear blank is always on the processing axis during processing, improving the processing quality, and having stable use. Under the combined action of the two sets of bevel gear sets, the synchronous main shaft 202 and the two linkage secondary shafts 203 are always linked. That is, when the synchronous main shaft 202 rotates, it can drive the two linkage secondary shafts 203 to rotate synchronously, and when any one of the linkage secondary shafts 203 rotates, it can drive the other linkage secondary shaft 203 and the synchronous main shaft 202 to rotate synchronously. At the same time, since the synchronous gears b 2031 of the two linkage secondary shafts 203 and the synchronous gear a 2021 of the synchronous main shaft 202 are in one-to-one corresponding meshing transmission with the linkage gears 3021 of the three sets of clamping block mechanisms 3, when the control rod 302 of any one set of clamping block mechanisms 3 rotates, it can drive the synchronous main shaft 202 and the two linkage secondary shafts 203 to rotate synchronously. Furthermore, the control rods 302 of the three sets of clamping block mechanisms 3 will also rotate synchronously. When the control rods 302 of the three sets of clamping block mechanisms 3 rotate synchronously, the three action blocks 303 will move in the same direction, so as to realize the synchronous and co-directional movement of the three positioning clamping blocks 301 to change the clamping distance, and always be able to realize the function of automatic centering (it should be noted that when the three action blocks 303 move in the same direction, by changing the spiral direction of the linkage groove 3031, the rotation direction of the linkage block 304 can be controlled, so as to achieve the purpose of controlling the synchronous and co-directional movement of the three positioning clamping blocks 301, and the phenomenon that the three positioning clamping blocks 301 move in different directions will not occur), and the use is stable and efficient.

[0035] In an embodiment of the present disclosure, a track block 3032 with a regular polygon cross-section is provided on the side surface of the action block 303, and a track groove 2012 is provided inside the positioning seat 201. The track block 3032 is inserted into the inside of the track groove 2012. The track groove 2012 can limit the movement trajectory of the action block 303 inside the positioning seat 201 through the track block 3032, so that the action block 303 will not be skewed or distorted during movement regulation, resulting in the device getting stuck and failing, and the use is stable.

[0036] Specific usage method and function of this embodiment: In the present invention, since the positioning seat 201 is a "C"-shaped seat body and the fixing seat 101 is provided with an avoidance notch 1011, when loosening or clamping the gear shaft, it can be directly placed in or taken out from the top of the fixture assembly, and any position of the gear shaft can be quickly fixed for processing. The clamping block mechanism 3 can fix gear shafts with different outer diameters inside the positioning seat 201, which is convenient for processing different types of gear shafts and gear blanks, and has extremely strong adaptability. When the control rod 302 is rotated, the control rod 302 can drive the action block 303 to move inside the positioning seat 201 through the rod thread. When the positioning seat 201 moves, the linkage groove 3031 can drive the linkage block 304 to rotate by the linkage protrusion 3042. When the linkage block 304 rotates, the clamping and loosening gear 3041 can drive the positioning clamping block 301 to move radially along the positioning seat 201 through the clamping and loosening rack 3011, thereby changing the clamping inner diameter of the positioning clamping block 301, and thus facilitating the quick clamping and fixing operation of different types and outer diameter gear shafts and gear blanks. Under the combined action of the synchronization mechanism and the three groups of clamping block mechanisms 3, the fixture assembly can realize the operation of automatically centering and fixing the gear shaft, ensuring that the rotation axis of the gear shaft and the gear blank is always on the processing axis during processing, improving the processing quality, and being stable in use. Under the combined action of the two groups of bevel gear sets, the synchronous main shaft 202 and the two linkage sub-shafts 203 are always linked, that is, when the synchronous main shaft 202 rotates, it can drive the two linkage sub-shafts 203 to rotate synchronously, and when any one of the linkage sub-shafts 203 rotates, it can drive the other linkage sub-shaft 203 and the synchronous main shaft 202 to rotate synchronously. At the same time, since the synchronous gear b2031 of the two linkage sub-shafts 203, the synchronous gear a2021 of the synchronous main shaft 202 and the linkage gears 3021 of the three groups of clamping block mechanisms 3 are in one-to-one corresponding meshing transmission, when the control rod 302 of any one group of clamping block mechanisms 3 rotates, it can drive the synchronous main shaft 202 and the two linkage sub-shafts 203 to rotate synchronously. Furthermore, the control rods 302 of the three groups of clamping block mechanisms 3 will also rotate synchronously. When the control rods 302 of the three groups of clamping block mechanisms 3 rotate synchronously, the three action blocks 303 will also move in the same direction, so as to realize the synchronous and co-directional movement of the three positioning clamping blocks 301 to change the clamping distance, and always be able to realize the function of automatic centering (it should be noted that when the three action blocks 303 move in the same direction, by changing the spiral direction of the linkage groove 3031, the rotation direction of the linkage block 304 can be controlled, so as to achieve the purpose of controlling the synchronous and co-directional movement of the three positioning clamping blocks 301, and the phenomenon that the three positioning clamping blocks 301 move in different directions will not occur).
