Description

Technical Field

[0001] This utility model belongs to the technical field of tooth alignment devices, and relates to a tooth alignment device for fine tooth insertion after heating. Background Technology

[0002] To achieve high-precision spline machining and reduce the negative impact of thermal deformation, a process scheme of rough cutting before thermal cutting and fine cutting after thermal cutting is adopted. In the fine cutting stage after thermal cutting, since the blank already has a tooth profile, it is crucial to accurately align the teeth before cutting in order to ensure that each gear blank and the cutting tool maintain a specific relative position, ensure uniform tooth thickness removal, and thus achieve the required tooth profile, tooth direction, and other tooth accuracy of the spline.

[0003] However, the gear shaping machines used in actual processing do not have a built-in gear setting mechanism. Currently, when precision shaping splines after heating, gear setting is usually achieved manually by the machine tool operator, that is, the operator visually inspects the position of each gear blank and the shaping tool, and manually ensures the relative position of the two.

[0004] This manual tooth alignment method has many drawbacks: First, the processing efficiency is extremely low, as operators need to spend a long time visually inspecting, adjusting, and judging the position; second, it places strict requirements on operators, as the human eye cannot easily detect millimeter-level positional changes, resulting in a high error rate and large errors, leading to poor precision of the machined parts, increased scrap rate, and increased production costs; third, during manual tooth alignment, personnel need to enter the machine tool, operate the machine tool to adjust the position while visually inspecting, which poses significant safety hazards and can easily lead to safety accidents. Utility Model Content

[0005] The purpose of this utility model is to provide a device for precision tooth alignment after heating, so as to solve the technical problems of low efficiency, low accuracy and safety hazards in manual tooth alignment after heating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses a post-heating precision tooth-aligning device, comprising: Positioning plate, used for fixing and connecting machine tools; The positioning plate is slidably connected to the gear gauge seat, and the sliding direction of the gear gauge seat is parallel to the axial direction of the gear blank to be tested. The first limiting part is used to fix the gear gauge seat on the positioning plate after the gear gauge seat moves to the target position on the positioning plate; The connecting rod is slidably connected to the tooth gauge seat; The second limiting part is used to fix the connecting rod on the gear gauge seat after the connecting rod moves to the target position on the gear gauge seat; The connecting rod is detachably and fixedly connected to the gear gauge.

[0007] Furthermore, the positioning plate has several bolt holes, and screws are inserted into the bolt holes to fix the positioning plate to the machine tool.

[0008] Furthermore, the positioning plate is provided with a T-slot slide rail, and the tooth gauge seat is provided with a T-slot nut, the end of which is slidably embedded in the T-slot slide rail.

[0009] Furthermore, the first limiting part also includes a first bolt, which passes through the tooth gauge seat and is threadedly connected to the T-slot with a nut.

[0010] Furthermore, the gear gauge seat includes a first seat body and a second seat body fixedly connected. The first seat body and the second seat body are perpendicular to each other. The first seat body is slidably connected to the positioning plate, and the second seat body is slidably connected to the connecting rod. The connecting rod is parallel to the length direction of the first seat body.

[0011] Furthermore, the connecting rod is provided with a mushroom-shaped handle, which is located on the side close to the positioning plate.

[0012] Furthermore, the connecting rod is movably mounted on the tooth gauge seat; The second limiting part includes: A long keyway is formed on the connecting rod; The limiting set screw and the hexagonal nut are threaded together, and the limiting set screw, the hexagonal nut and the tooth gauge seat are all threaded together. The end of the limiting set screw is located in the long keyway.

[0013] Furthermore, the toothed gauge is embedded in the connecting rod, and the toothed gauge and the connecting rod are connected by a thread.

[0014] Furthermore, the tooth gauge is provided with a measuring ball.

[0015] Furthermore, it also includes a clamp for fixing the tooth blank to be aligned.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The positioning plate is used to fix the machine tool, serving as a fixed connection component between the entire gear setting device and the machine tool. The gear setting gauge seat is slidably connected to the positioning plate, and the sliding direction of the gear setting gauge seat is parallel to the axial direction of the gear blank to be tested, realizing the position adjustment of the gear setting gauge along the axial direction of the gear blank. A first limiting part is used to fix the gear setting gauge seat on the positioning plate after it has moved to the target position, ensuring the stability of the gear setting gauge in the axial position. A connecting rod is slidably connected to the gear setting gauge seat, realizing the radial position adjustment function of the gear setting gauge along the workpiece. A second limiting part is used to fix the connecting rod on the gear setting gauge seat after it has moved to the target position, ensuring that the connecting rod will not move radially during gear setting. The gear setting gauge is detachably fixedly connected to the connecting rod, making the gear setting gauge a replaceable component. This facilitates the replacement of gear setting gauges with more suitable measuring ball diameters according to the module of different workpieces. This invention achieves flexible adjustment of the axial and radial positions of the gear gauge by axial sliding and fixing of the gear gauge seat on the positioning plate, radial sliding and fixing of the connecting rod on the gear gauge seat, and a detachable design for the gear gauge and connecting rod.

Furthermore, it avoids the safety hazards of personnel entering the machine tool during manual gear alignment, improving the safety of the production process. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1: See Figures 1 to 3 This embodiment discloses a post-heating precision tooth setting device, including: a positioning plate 1, a tooth setting gauge seat 2, a first limiting part 203, a connecting rod 3, a second limiting part 305, and a tooth setting gauge 4.

[0022] See Figure 1 The positioning plate 1 is used to fix the machine tool 5, serving as a fixed connection component between the entire gear-setting device and the machine tool 5, ensuring that the device is fixed in position on the machine tool.

[0023] See Figure 1 and Figure 2 In this embodiment of the utility model, the positioning plate 1 has a plurality of bolt holes, and screws 102 are inserted into the bolt holes. The screws 102 are used to fix the positioning plate 1 to the machine tool 5.

[0024] See Figure 1 and Figure 2The positioning plate 1 is slidably connected to the gear gauge seat 2. The sliding direction of the gear gauge seat 2 is parallel to the axial direction of the gear blank 6 to be tested. Through this sliding connection, the position of the gear gauge 4 along the axial direction of the gear blank 6 to be tested is adjusted. The operator can flexibly move the gear gauge seat 2 according to the different axial dimensions and positional requirements of the gear blank 6 to be tested, so that the gear gauge 4 can accurately reach the appropriate axial position, meet the gear matching requirements of different gear blanks 6 to be tested, and improve the versatility and adaptability of the device.

[0025] See Figure 2 and Figure 3 In this embodiment of the utility model, the positioning plate 1 is provided with a T-slot slide rail 101, and the tooth gauge seat 2 is provided with a T-slot nut 201. The end of the T-slot nut 201 is slidably embedded in the T-slot slide rail 101.

[0026] See Figure 2 In this embodiment of the present invention, the tooth gauge seat 2 includes a first seat 204 and a second seat 205 fixedly connected. The first seat 204 and the second seat 205 are perpendicular to each other. The first seat 204 is slidably connected to the positioning plate 1, and the second seat 205 is slidably connected to the connecting rod 3. The connecting rod 3 is parallel to the length direction of the first seat 204.

[0027] The first limiting part 203 is used to fix the tooth gauge seat 2 on the positioning plate 1 after the tooth gauge seat 2 moves to the target position on the positioning plate 1, thereby ensuring the stability of the tooth gauge 4 in the axial position and thus ensuring the accuracy and reliability of tooth alignment.

[0028] See Figure 2 In this embodiment of the present invention, the first limiting part 203 further includes a first bolt 202, which passes through the tooth gauge seat 2 and is threadedly connected to the T-slot nut 201.

[0029] See Figure 1 and Figure 2 The connecting rod 3 is slidably connected to the tooth gauge seat 2, realizing the position adjustment function of the tooth gauge 4 along the radial direction of the workpiece. The operator can flexibly move the connecting rod 3 according to the radial dimensions and tooth characteristics of the tooth blank 6 to be inspected, so that the tooth gauge 4 can accurately reach the appropriate radial position, so as to perform tooth alignment operation with the tooth blank 6 more accurately, further improving the adaptability of the device to different workpieces and the accuracy of tooth alignment.

[0030] See Figures 1 to 3 In this embodiment of the present invention, the connecting rod 3 is provided with a mushroom-shaped handle 301, which is located on the side close to the positioning plate 1.

[0031] The second limiting part 305 is used to fix the connecting rod 3 on the tooth gauge seat 2 after the connecting rod 3 moves to the target position. This ensures that the connecting rod 3 will not move radially during the tooth alignment process, thereby ensuring the stability of the tooth gauge 4 in the radial position and providing a reliable guarantee for accurate tooth alignment. It effectively avoids tooth alignment errors caused by the movement of the connecting rod 3.

[0032] Referring to 1 and 2, in this embodiment of the present invention, the connecting rod 3 is movably mounted on the tooth gauge seat 2; The second limiting part 305 includes: A long keyway 302 is formed on the connecting rod 3; The limiting set screw 303 and the hexagonal nut 304 are threaded together with the limiting set screw 303, the hexagonal nut 304 and the tooth gauge seat 2. The end of the limiting set screw 303 is located in the long keyway 302.

[0033] See Figures 1 to 3 The gear guide 4 is detachably and fixedly connected to the connecting rod 3, making the gear guide 4 a replaceable component. This facilitates the replacement of the gear guide with a more suitable measuring ball diameter according to the module of different workpieces, greatly improving the flexibility of the device. This allows the same device to be used for gear setting on workpieces with various modules, expanding the application range of the device and reducing the cost of replacing the entire device when changing workpieces.

[0034] In this embodiment of the utility model, the tooth gauge 4 is embedded in the connecting rod 3, and the tooth gauge 4 and the connecting rod 3 are connected by threads.

[0035] See Figures 1 to 3 In this embodiment of the present invention, the tooth gauge 4 is provided with a measuring ball 401.

[0036] See Figures 1 to 3 In this embodiment of the invention, a clamp 7 is also included, which is used to fix the tooth blank 6 to be aligned.

[0037] This invention achieves flexible adjustment of the axial and radial positions of the gear gauge 4 by axially sliding and fixing the gear gauge seat 2 on the positioning plate 1, radially sliding and fixing the connecting rod 3 on the gear gauge seat 2, and detachable design of the gear gauge 4 and the connecting rod 3. It also possesses good flexibility. It can accurately align the gears according to the height, diameter, and module of different workpieces, effectively replacing the original manual gear alignment method. This reduces the difficulty of gear alignment, eliminating the need for operators to rely on the high-difficulty, high-error manual visual inspection, thus improving alignment efficiency. Simultaneously, the precise adjustment and stable fixation of the device ensure the accuracy of gear alignment, reducing problems such as poor part machining accuracy and high scrap rate caused by gear alignment errors, thereby reducing production costs. Furthermore, it avoids the safety hazards of personnel entering the machine tool during manual gear alignment, improving the safety of the production process.

[0038] Example 2: See Figures 1 to 3 This embodiment discloses a post-heating precision gear setting device, including a positioning plate 1, a gear setting seat 2, a connecting rod 3, a gear setting gauge 4, a limiting set screw 303, and other components; The center of the positioning plate 1 is a long T-slot slide rail 101, with four threaded holes on both sides. The screws installed through the threaded holes are used to connect and fix the plate to the bed of the machine tool 5. The tail of the gear gauge seat 2 is embedded in the T-slot slide rail 101 of the positioning plate 1 and can move relative to it. The position of the gear gauge seat 2 is adjusted and fixed on the positioning plate 1 by the first bolt 202 and the T-slot nut 201. The head of the gear gauge seat 2 has a hole and is connected to the body of the connecting rod 3 through clearance fit, so that the connecting rod 3 can move relative to the hole in the gear gauge seat 2. The tail of the connecting rod 3 has a mushroom-shaped handle 301, which is convenient for manual adjustment of the relative position. The connecting rod has a long keyway 302. The limiting set screw 303 fixes the position of the connecting rod through the threaded hole on the side of the gear gauge seat 2 and the long keyway 302. The head of the connecting rod 3 is connected to the gear gauge 4 through thread fit. The measuring ball 401 on the head of the gear gauge 4 is embedded in the tooth groove of the gear blank 6 and makes close contact with the tooth sides on both sides, thereby constraining the circumferential position of the gear blank and achieving precise tooth alignment.

[0039] This invention achieves positional adjustment of the gear gauge 4 along the axial direction of the workpiece gear blank 6 by the mutual movement and fixation of the gear gauge seat 2 on the positioning plate 1. Simultaneously, the mutual movement and fixation of the connecting rod 3 within the gear gauge seat 2 achieves radial positional adjustment of the gear gauge 4 along the workpiece. The separate design of the gear gauge 4 and the connecting rod 3 makes the gear gauge 4 a replaceable component, allowing for matching a gear gauge 4 with a more suitable diameter of the measuring ball 401 according to the module of different workpieces. This invention possesses excellent flexibility, applicable to gear blank workpieces of different heights, diameters, and modules, replacing the original manual gear alignment method, significantly reducing the difficulty of gear alignment, increasing efficiency, and improving accuracy.

[0040] Based on the above structure, the working principle of this utility model is as follows: Step 1: Install the gear blank 6 to be processed on the fixture 7 and determine the initial position of the gear blank 6; at the same time, install the end face of the positioning plate 1 without T-slot slide rail 101 tightly against the bed of the machine tool 5 and connect and fix it with four screws.

[0041] Step 2: Insert the tail of the gear gauge seat 2 into the T-slot slide rail 101 of the positioning plate 1, slide the gear gauge 4 to adjust its height to be roughly aligned with the middle position of the spline to be machined on the gear blank 6, and fix the position of the gear gauge seat 2 and the positioning plate 1 by the two first bolts 202 and the T-slot nut 201.

[0042] Step 3: The connecting rod 3 is inserted into the hole at the head of the tooth gauge seat 2 through a micro-clear fit with the shaft. The tail of the connecting rod 3 is connected to a mushroom-shaped handle 301 by a thread on the side near the positioning plate 1. Move the handle 301 along the axial direction of the connecting rod 3 to adjust the relative position of the connecting rod 3 and the tooth gauge seat 2, so that the distance between the head of the connecting rod 3 and the major diameter of the spline of the tooth blank 6 is slightly greater than the length of the tooth gauge 4. After the position is determined, it is fixed by the limiting set screw 303 and the hexagonal nut 304.

[0043] Step 4: Connect the two by matching the external thread at the tail of the gear gauge 4 with the internal thread at the head of the connecting rod 3. At this point, the initial installation of the device is complete.

[0044] Step 5: Loosen the limiting set screw 303 and hexagonal nut 304 to make fine adjustments so that the measuring ball 401 of the head of the gear gauge 4 is just embedded in the spline groove of the gear blank 6 and closely fits the tooth surfaces on both sides, thereby fixing the circumferential position of the gear blank 6. Finally, tighten the limiting set screw 303 and hexagonal nut 304 to fix the final position of the gear gauge 4. After the gear alignment is completed, the gear gauge 4 and connecting rod 3 are retracted and avoided by loosening the limiting set screw 303 and hexagonal nut 304.

[0045] The gear-setting device is installed on the other side of the cutter shaft, so it will not interfere with the cutter shaft during workpiece cutting. After the workpiece is finished, the next workpiece is replaced, and step five is repeated. The gear gauge 4 is a quick-change part, and different series of gear gauges 4 with different ball diameters can be designed as needed. By changing them, the flexibility of the device can be improved, meeting the processing needs of a variety of products.

[0046] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of this utility model.
