Description

Technical Field

[0001] The invention relates to the technical field of gear shaping, in particular to a self-clamping and limiting gear shaping tool fixture. Background Art

[0002] The gear shaping fixture is mainly used as a device for clamping the gear shaping during the gear shaping process. The gear shaping process is generally achieved by mounting the gear shaping cutter on the tool spindle and performing rotation and up and down reciprocating shaping motions. For example, in the patent with the announcement number "CN117644249A" and the name "A gear shaping machine fixture and fixing method", the third spring is in a free extension state. In the process of the second clamping plate pushing the workpiece to move, the workpiece is gradually brought into contact with the push block and thrust is applied to the push block. Then, under the action of the thrust, the push block drives the baffle to move along the air cavity. At this time, the third spring is squeezed and has a tendency to recover. During the movement of the baffle, the pressure in the space in the air cavity on the side of the baffle away from the third spring decreases. Then, when the push block is out of contact with the outside world, the third spring reaches the maximum compression degree, and at this time, the baffle enters the third air pipe, and then the space in the air cavity on the side of the baffle away from the third spring is inhaled through the third air pipe and the annular groove. Then, under the action of the air flow, the workpiece is sucked together with the placement plate, which plays a role in improving the workpiece fixing effect. However, the above structure still has the following problems in actual use:

[0003] The above structure improves the workpiece fixing effect by sucking the workpiece and the placement plate together under the action of airflow. However, in actual use, the above structure can only play the role of clamping and limiting, and its functionality is relatively simple. In addition, the fixing method through airflow will cause the fixing effect to be unstable. When a small amount of air leakage occurs, it is easy to cause the gear clamping to loosen.

The specific contents are as follows:

[0019] The gear ring rotates, thereby driving the fixed turntable to rotate together, and the arc groove is driven to rotate during the rotation of the turntable, so that the slide bar slides in the arc groove.

At the same time, the production quality of the gear is improved, and there is no need to provide power separately, which reduces the production cost of the device and increases functionality. Finally, through the setting of the discharge pipe, the waste generated during processing can be discharged to avoid the accumulation of waste. At the same time, there is no need for manual cleaning, and the need for repeated cleaning that affects production efficiency is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 9 , the present invention provides the following technical solutions:

[0036] Embodiment 1: In order to solve the problem that the prior art can only play the role of clamping and limiting, its functionality is relatively simple, and the fixing method through airflow will cause the fixing effect to be unstable. When a small amount of air leakage occurs, it is easy to cause the gear clamping to loosen. Therefore, the following scheme is disclosed, including a processing table 1 and a column 2 fixed on the upper surface of the processing table 1 for installing a processing component 3, and the column 2 is arranged in an inverted "L" shape, and the processing component 3 is installed on the lower surface of one end of the column 2; it also includes: a base 4 is fixed on the upper surface of the processing table 1, and a placing table 5 is arranged above the base 4, and the placing table 5 is fixed to the base 4 by bolts formed between the fixing feet 6, and at the same time, a clamping mechanism is arranged on the upper surface of the placing table 5, and the clamping and limiting of the gear is realized by four groups of clamping blocks 13; a gear is embedded in the middle of the placing table 5, A ejection mechanism is provided below the placement table 5, and the lifting ring 22 is lifted and lowered by the lifting rod 20 to eject the processed slotted gear. The clamping mechanism includes a servo motor 7 and a first gear 8, wherein the servo motor 7 is fixed inside the base 4, and the first gear 8 is fixed to the output end of the servo motor 7, and the outer side of the first gear 8 is meshed with the gear ring 9, the upper end of the gear ring 9 is fixed to the turntable 10, and the turntable 10 is arranged below the placement table 5, and an arc groove 11 is provided on the surface of the turntable 10, and a slide bar 12 is slidably provided inside the arc groove 11, and the upper end of the slide bar 12 passes through the placement table 5 and is fixed to the clamping block 13, and a sliding connection is formed between the slide bar 12 and the placement table 5, and a protective pad 14 is bonded to the inner side of the clamping block 13, and four groups of clamping blocks 13 are provided, and the clamping is more stable through the four groups of clamping blocks 13.

[0037] First, place the insert gear in the embedding groove on the upper surface of the placement table 5, and process the insert gear through the processing assembly 3 installed on the column 2. At the same time, when the insert gear is placed in the embedding groove on the upper surface of the placement table 5, the servo motor 7 can be started at this time, and the servo motor 7 drives the first gear 8 to rotate, and then the first gear 8 drives the meshing gear ring 9 to rotate together, and the gear ring 9 rotates, thereby driving the fixed turntable 10 to rotate together, and the arc groove 11 is driven to rotate during the rotation of the turntable 10, so that the slide bar 12 slides in the arc groove 11, and when the slide bar 12 slides in the arc groove 11, the slide bar 12 also drives the clamping block 13 It moves inward, so that the clamping block 13 drives the protective pad 14 to contact the slotting gear, thereby fixing the slotting gear. Compared with the airflow type fixing method, this structure is more stably fixed and is not prone to the phenomenon of feeding, thereby ensuring the stability during the slotting gear processing. The setting of the protective pad 14 not only plays a protective role, but also has an anti-slip effect, thereby improving stability while providing protection. When the limit needs to be released later, it is only necessary to control the first gear 8 to drive the gear ring 9 to reverse, thereby making the turntable 10 reverse together and making the slide bar 12 drive the clamping block 13 to slide outward through the arc groove 11, thereby releasing the limit.

[0038] Embodiment 2: A new technical solution is added on the basis of Embodiment 1, so that it is convenient for the staff to take the processed gear shaping. For details, refer to Figure 3-Figure 7 The ejection mechanism includes a pull rope 16 and a rotating rod 17, wherein one end of the pull rope 16 is fixed to the sliding rod 12, and the other end of the pull rope 16 is wound around the outside of the rotating rod 17, and the front and rear ends of the rotating rod 17 are connected to the bearing of the placement table 5, and at the same time, a torsion spring 18 is sleeved on the outside of the other end of the rotating rod 17, and a second gear 19 is fixed to the middle outer side of the rotating rod 17, and the second gear 19 is meshed with the lifting rod 20 through a connecting tooth block 21, and the connecting tooth blocks 21 are vertically and evenly spaced on the outside of the lifting rod 20.

[0039] When the slide bar 12 slides outward, it also drives one end of the pull rope 16 to move together, so that the pull rope 16 generates tension and pulls the rotating rod 17 to rotate, so that the rotating rod 17 rotates and drives the lifting rod 20 to rise by meshing with the connecting tooth block 21, so that the lifting rod 20 drives the lifting circle 22 to rise together during the lifting process, so that the lifting circle 22 pushes the inserting gear out of the placement table 5 while rising, so as to facilitate the removal of the processed inserting gear, and when the slide bar 12 moves inward and drives the clamping block 13 to clamp the inserting gear, the slide bar 12 no longer generates tension on the pull rope 16. At this time, the elastic force of the torsion spring 18 can drive the rotating rod 17 to reverse, so that the rotating rod 17 drives the lifting rod 20 to descend through the second gear 19, so that the lifting rod 20 drives the lifting circle 22 to descend together, so that the lifting circle 22 no longer contacts the inserting gear, thereby avoiding affecting the processing;

[0040] Embodiment 3: A new technical solution is added on the basis of Embodiment 2, and the burrs at the lower end of the gear are polished, so that workers do not need to remove the burrs separately, thereby reducing the burrs and improving the efficiency, and at the same time improving the production quality of the gear. For details, refer to Figure 5-Figure 9 The upper end of the lifting rod 20 is fixed to the lifting ring 22, and the lifting ring 22 is arranged below the inserting gear. At the same time, the internal rotation of the lifting ring 22 is connected with a grinding ring 26, and the upper end of the grinding ring 26 contacts the inserting gear. At the same time, the outer side of the lower end of the grinding ring 26 has meshing teeth at equal intervals, and the grinding ring 26 is meshed with the third gear 25 through the meshing teeth. The third gear 25 is fixed to the outer side of the upper end of the spiral rod 23, and the upper end of the spiral rod 23 is connected to the bearing of the lifting ring 22, and the lower end of the spiral rod 23 passes through the sleeve 24, and a fixing block is arranged on the inner side of the sleeve 24, and the fixing block is slidably connected with the spiral groove below the spiral rod 23, and the sleeve 24 is fixed to the inside of the placing table 5, and a fitting groove is opened in the middle part of the placing table 5, and a discharge pipe 15 is fixed in the fitting groove, and the lower end of the discharge pipe 15 passes through the turntable 10 and the base 4.

[0041] Moreover, when the lifting ring 22 is lifted, it will also drive the screw rod 23 to lift together, so that during the lifting process of the screw rod 23, the sliding connection with the fixed block in the sleeve 24 is formed, so that the screw rod 23 rotates during the lifting process, and the screw rod 23 drives the third gear 25 to rotate during the self-rotation, so that the third gear 25 rotates while driving the grinding ring 26 to rotate, so that the grinding ring 26 rotates while grinding the burrs on the lower end of the gear. There is no need for workers to remove the burrs separately, thereby reducing the burrs and improving the efficiency. At the same time, the production quality of the gear is improved, and there is no need to provide power separately, which reduces the production cost of the device and increases the functionality. Finally, through the setting of the discharge pipe 15, the waste generated during the processing can be discharged to avoid the accumulation of waste. At the same time, there is no need for manual cleaning, and the need for repeated cleaning to affect the production efficiency is avoided.
