Description

Technical Field

[0002] Gears are a commonly used part in mechanical equipment. Their function is to accurately transmit power and adjust the speed and direction of movement. With the continuous development of industry, in order to ensure the smoothness of power transmission, reduce vibration and noise, and extend the service life, the requirements for the precision of gear production are getting higher and higher.

[0003] The existing positioning device for gear processing adopts a rotating disk placed on an operating table, on which a specific column is fixedly installed, and the inner hole of the gear blank to be processed is directly sleeved on the column, and the matching nut is rotated and moved downward so that the bottom surface of the nut abuts against the end surface of the gear blank, and the nut and the rotating disk jointly apply force to clamp the two ends of the gear blank to form a pre-processing positioning. In the actual process of processing tooth grooves, in order to meet the processing requirements of tooth grooves at different angles, the rotating disk needs to rotate continuously. Due to the differences in the inner diameters of different gear blanks, there are gaps between them and the column, and complete fit cannot be achieved. When the rotating disk rotates, if the nut and the gear blank slip, lateral shaking will occur, which will directly affect the accuracy of the gear blank in processing tooth grooves and reduce the overall processing quality of the gear blank.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a positioning device for gear processing is provided, in order to achieve a more practical purpose. Utility Model Content

Through holes connected to the corresponding interior of the moving chambers are provided on both sides of the column, and a connecting rod is provided on the outer side of the moving block. One end of the connecting rod passes through the through hole and is connected to the support plate. Grooves are provided on both sides of the connecting rod, and a plurality of locking holes are provided in parallel on the connecting rod. The grooves are connected to one of the locking holes on the corresponding connecting rod by bolts, and the rotating disk is driven by a motor.

[0010] Furthermore, the outer side wall of the support plate is arc-shaped.

[0011] Furthermore, a rubber layer is bonded to the outer side wall of the support plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting up a moving chamber and a moving block, moving chambers are opened on both sides of the smooth part of the column, and moving blocks are slidably set in the moving chambers. The outer side of the moving block is connected to the support plate through a connecting rod. By opening a groove on the column and opening a plurality of locking holes in parallel and linearly on the connecting rod, a bolt is passed through the groove on the column to quickly lock one of the locking holes on the connecting rod.

[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides a positioning device for gear processing, comprising an operating table 1, the operating table 1 is used to provide a stable platform, the top of the operating table 1 is rotatably connected to a rotating disk 2, a motor is installed at the bottom of the operating table 1, the output shaft of the motor passes through the operating table 1 and is connected to the rotating disk 2, the motor drives the rotating disk 2 to rotate, a column 5 is fixedly arranged on the rotating disk 2, a gear blank 3 to be processed is placed on the rotating disk 2, the inner hole of the gear blank 3 to be processed is sleeved on the column 5, and the rotation of the rotating disk 2 can meet the tooth groove processing requirements of the gear blank 3 at different angles;

[0026] The lower half of the column 5 is a smooth portion 7, and moving chambers 15 are provided on both sides of the smooth portion 7 of the column 5. Moving blocks 11 are slidably arranged in the two moving chambers 15. Through holes 10 connected to the corresponding interiors of the moving chambers 15 are provided on both sides of the column 5. A connecting rod 12 is provided on the outer side of the moving block 11, and one end of the connecting rod 12 passes through the through hole 10 and is connected to the inner wall of the support plate 13. The support plate 13 can be used to support the inner hole wall of the gear blank 3. The operator manually pushes the support plate 13 outward to drive the moving block 11 to move outward synchronously in the moving chamber 15, so that the outer wall of the manually adjusted support plate 13 is closely fitted with the inner hole wall of the gear blank 3, thereby realizing the preliminary positioning of the inner hole wall of the gear blank 3.

[0027] Both sides of the column 5 are provided with grooves 8 located on both sides of the connecting rod 12, and a plurality of locking holes 14 are provided on the connecting rod 12 in parallel and linearly. The setting of the plurality of locking holes 14 can adjust the inner hole sizes of several specific different gear blanks 3 to meet diverse processing requirements. The groove 8 is connected to one of the locking holes 14 on the corresponding connecting rod 12 through a bolt 9, and the bolt 9 is used to pass through the groove 8 on the column 5 and one of the locking holes 14 on the connecting rod 12 for quick locking, thereby ensuring that the outer wall of the support plate 13 and the inner hole wall of the gear blank 3 are firmly positioned. In actual operation, the operator can select a suitable gear blank from the inner hole sizes of several specific different gear blanks 3 according to the adjusted position of the support plate 13. 3, so that the outer wall of the support plate 13 is closely fitted with the inner hole of the gear blank 3, avoiding the nut 4 and the gear blank 3 from slipping and causing lateral shaking when the rotating disk 2 rotates. If the operator needs to replace the gear blank 3 to be processed, the processed gear can be removed from the column 5, and the locking of the connecting rod 12 can be released by loosening and removing the bolt 9. Subsequently, the operator adjusts the position of the manual support plate 13 again according to the inner hole size of the gear blank 3 to be processed, and uses the locking hole 14 on the bolt 9 and the connecting rod 12 to quickly lock again. Finally, the inner hole of the gear blank 3 to be processed is directly sleeved on the column 5, and the gear blank 3 is placed on the rotating disk 2, and the gear processing process can be started, thereby improving the processing quality of the gear blank 3.

[0028] The upper half of the column 5 is provided with a thread, and a nut 4 is threadedly sleeved on the threaded portion 6 of the column 5. The nut 4 cooperates with the threaded portion 6 of the column 5, and the operator manually rotates the nut 4 so that it can move downward along the axial direction of the column 5. The bottom surface of the nut 4 applies downward pressure on the end face of the gear blank 3. The nut 4 and the rotating disk 2 work together to clamp the gear blank 3 axially, further improving the positioning stability.

[0029] A guide assembly is also provided on the rotating disk 2, which includes slide grooves 16 opened on both sides of the top of the rotating disk 2. The slide grooves 16 are connected to the bottom of the corresponding support plates 13 through sliders 17. The setting of the slide grooves 16 and the sliders 17 enhances the guidance and stability of the support plates 13 during the outward movement.

[0030] Among them, the outer wall of the support plate 13 is arc-shaped, so that when the support plate 13 contacts the inner hole wall of the gear blank 3, it can better adapt to its curved surface, and the pressure exerted by the support plate 13 on the gear blank 3 during the fixing process is more uniform, thereby improving the positioning stability.

[0031] Among them, a rubber layer is bonded to the outer wall of the support plate 13, which has good elasticity and wear resistance, can provide buffering, reduce the hard contact of the support plate 13 with the inner hole wall in the gear blank 3 during the fixing process, and avoid scratches on the inner hole wall of the gear blank 3. At the same time, during the process of close fitting, the friction force is increased for the outer side surface of the support plate 13, and the gear blank 3 is prevented from sliding due to cutting force during processing, thereby further improving the positioning stability.

[0032] When using:

[0033] The operator can manually push the support plate 13 outwards according to the inner hole size of the gear blank 3 to be processed. The outward movement of the support plate 13 will drive the moving block 11 to move outward synchronously in the moving chamber 15, and use the bolt 9 to quickly lock the groove 8 and one of the locking holes 14 on the corresponding connecting rod 12 to ensure that the position of the support plate 13 is firmly positioned. Subsequently, the inner hole of the gear blank 3 to be processed is directly sleeved on the column 5, and it is placed above the rotating disk 2, so that the outer wall of the support plate 13 after manual adjustment is tightly fitted with the inner hole wall of the gear blank 3. Finally, by manually rotating the nut 4, the nut 4 rotates and moves downward, and gradually applies axial pressure to the gear blank 3. Under the joint action of the nut 4 and the rotating disk 2, the gear blank 3 is clamped and fixed, thereby avoiding the nut 4 and the gear blank 3 from slipping and causing lateral shaking when the rotating disk 2 rotates, thereby improving the production quality of the gear blank 3 processing.
