Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically a positioning device for gear production and processing. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. Gears are one of the basic transmission components required for motion transmission in existing mechanical equipment. Gear processing methods are mainly divided into two categories: forming method and generating method, covering more than ten specific processes such as gear milling, gear hobbing, gear shaping, gear shaving, and gear grinding, supplemented by special processing technologies such as wire cutting and powder metallurgy. During gear processing, gears often need to be positioned. These gear positioning components and tools are collectively referred to as positioning devices.

[0003] Existing gears require different positioning tools for machining the external and internal teeth due to their different tooth positions, which increases the preparation time for gear machining. Therefore, they do not meet the current requirements. In response, we propose a positioning device for gear manufacturing. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for gear manufacturing and processing, so as to solve the problems mentioned in the background art, such as the need to change different positioning tools for processing the external and internal teeth of gears due to different tooth positions, which leads to an increase in gear processing preparation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for gear manufacturing and processing, comprising a mounting base, three fixing pins fixed on the upper surface of the mounting base, a rotating plate rotatably mounted on the outer side of the fixing pins, a positioning block fixed at the end of the rotating plate away from the fixing pins, a clamping screw detachably mounted above the positioning block, a pressure plate slidably mounted on the outer side of the clamping screw, a first positioning hydraulic rod provided on one side of the rotating plate, a second positioning hydraulic rod provided on the other side of the rotating plate, and the first positioning hydraulic rod and the second positioning hydraulic rod being fixed to the mounting base.

[0006] Preferably, a circular hole is provided through the center of the mounting base, and the size of the circular hole is larger than the diameter of the inner ring of the gear.

[0007] Preferably, the fixing pins and rotating plates are arranged in a circular array around the axis of the mounting base, and the height difference between the top of the positioning block and the upper surface of the rotating plate is less than the thickness of the gear.

[0008] Preferably, the end of the rotating plate connected to the positioning block is provided with a reserved groove, the depth of which is half the height of the rotating plate.

[0009] Preferably, the top of the positioning block is provided with a screw hole, and the bottom end of the clamping screw is inserted into the inside of the screw hole and connected to the positioning block by a thread.

[0010] Preferably, the large end of the pressure plate is provided with a through-hole, and the diameter of the through-hole is larger than the outer diameter of the thread of the clamping screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a first positioning hydraulic rod and a second positioning hydraulic rod to push a rotating plate and a positioning block to rotate around the axis of a fixed pin, adjusting the position of the positioning block. Thus, the gear is clamped and positioned from the inner or outer ring of the gear through the three positioning blocks, which can simultaneously meet the clamping operation of the inner ring size and the outer ring gear, without the need to change the clamping parts, shortening the preparation time and improving the gear processing efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4As shown, a positioning device for gear manufacturing includes a mounting base 1. Three fixing pins 3 are fixed on the upper surface of the mounting base 1. A rotating plate 4 is rotatably mounted on the outer side of the fixing pins 3. A positioning block 5 is fixed on the end of the rotating plate 4 away from the fixing pins 3. A clamping screw 10 is detachably mounted above the positioning block 5. A pressure plate 11 is slidably mounted on the outer side of the clamping screw 10. A first positioning hydraulic rod 6 is provided on one side of the rotating plate 4, and a second positioning hydraulic rod 7 is provided on the other side of the rotating plate 4. The first positioning hydraulic rod 6 and the second positioning hydraulic rod 7 are fixed to the mounting base 1. The rotating plate 4 and the positioning block 5 are pushed to rotate around the axis of the fixing pins 3 by the first positioning hydraulic rod 6 and the second positioning hydraulic rod 7, thereby adjusting the position of the positioning block 5. The gear is clamped and positioned from the inner or outer ring of the size by the three positioning blocks 5.

[0020] A circular hole 2 is provided through the center of the mounting base 1. The size of the circular hole 2 is larger than the diameter of the inner ring of the gear. The presence of the circular hole 2 allows the gear machining tool to bend and cut the gear in the thickness direction. During this process, the tool will not come into contact with the mounting base 1, ensuring the safety of the tool and the mounting base 1 during gear machining.

[0021] The fixing pins 3 and the rotating plate 4 are arranged in a circular array around the axis of the mounting base 1. The height difference between the top of the positioning block 5 and the upper surface of the rotating plate 4 is less than the thickness of the gear, so as to ensure that the pressure plate 11 contacts the upper surface of the gear when it is locked and applies downward pressure to the gear.

[0022] The end of the rotating plate 4 connected to the positioning block 5 is provided with a reserved groove 8. The depth of the reserved groove 8 is half the height of the rotating plate 4. The presence of the reserved groove 8 ensures that when the gear is being machined for the external teeth, the tool can completely cut the gear in the gear thickness direction, and the tool will not come into contact with the rotating plate 4, thus avoiding damage to the tool or the rotating plate 4.

[0023] The top of the positioning block 5 is provided with a screw hole 9. The bottom end of the clamping screw 10 is inserted into the inside of the screw hole 9 and is connected to the positioning block 5 by a thread. The large end of the pressure plate 11 is provided with a insertion hole. The diameter of the insertion hole is larger than the outer diameter of the thread of the clamping screw 10, so as to ensure that the pressure plate 11 can be smoothly assembled with the clamping screw 10. The clamping screw 10 can press the pressure plate 11 downward, so that the pressure plate 11 cooperates with the positioning block 5 to clamp the gear.

[0024] Working principle: When machining the gear teeth, first determine whether the gear being machined is an external tooth or an internal tooth. When machining the internal teeth, simply place the gear between the three positioning blocks 5, then connect the power to the second positioning hydraulic rod 7 and start it. The three second positioning hydraulic rods 7 start simultaneously and push the rotating plate 4 and the positioning blocks 5 to rotate around the axis of the fixing pin 3 until the three positioning blocks 5 contact and press against the outer ring of the gear. Then, use the clamping screw 10 and the pressure plate 11 to fix the gear from above. The internal teeth of the gear can be machined using a cutting tool. When machining the external teeth of the gear, the gear is placed on the outside of the three positioning blocks 5, and the first positioning hydraulic rod 6 is activated. The first positioning hydraulic rod 6 pushes the rotating plate 4, so that the positioning blocks 5 clamp the gear from the inside. The gear is fixed from above using the clamping screws 10 and the pressure plate 11. Then, the internal teeth of the gear can be machined using a cutting tool. This method can simultaneously meet the clamping operations of the inner ring size and the outer ring gear without changing the clamping parts, shortening the preparation time and improving the gear machining efficiency.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
