Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically to a gear drilling processing equipment. Background Technology

[0002] In gear manufacturing, drilling is a critical process, requiring the machining of mounting holes and positioning holes on the gear end face or gear ring. The accuracy of this process directly affects the subsequent assembly and performance of the gear. Currently, the mainstream fixing methods for gear drilling in the industry fall into two categories: one is to design a special fixing mold for gears with specific inner diameters, achieving positioning by adapting the fixing mold to the gear's inner diameter; the other is to use a universal chuck to hold the gear's outer diameter to fix the workpiece.

[0003] Existing fixing technology has significant drawbacks, especially in terms of adapting internal supports to different gears: the versatility of dedicated internal diameter fixing molds is extremely poor. When processing gears with different internal diameter specifications, it is necessary to frequently stop the machine to change the corresponding fixing molds. This not only greatly extends the operation time and reduces production efficiency, but also requires the stockpiling of multiple fixing molds, which significantly increases equipment procurement and maintenance costs and makes it difficult to meet the processing needs of gears with multiple specifications.

[0004] In view of this, a gear drilling machine is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a gear drilling equipment to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a gear drilling processing equipment, including a base plate, a gantry frame, and a drilling mechanism. A transmission box is provided on the top surface of the base plate, and a movable retaining block is provided on the top surface of the transmission box. The retaining block is generally stepped, and the outer edge of the retaining block is rounded. A through groove is opened through the top surface of the transmission box, and the bottom of the retaining block is located in the through groove. A rotatable transmission disc is installed on the bottom of the inner wall of the transmission box. A semi-circular transmission groove is opened on the inner wall of the transmission disc, and a movable transmission rod is provided inside the transmission groove. The top end of the transmission rod is fixedly connected to the through groove.

[0007] Furthermore, limiting grooves are formed on both sides of the inner wall of the through groove, and limiting blocks are fixedly installed on both sides of the bottom of the outer wall of the retaining block. The limiting blocks are adapted to the limiting grooves and are initially located inside the limiting grooves.

[0008] Furthermore, the specific number of the retaining blocks and through slots are four, and they are all distributed in a circular array.

[0009] Furthermore, a connecting block is fixedly installed on the side wall of the gantry frame. The specific number of the connecting blocks is two and they are arranged symmetrically. The transmission box is fixedly connected between the two gantry frames and does not directly contact the base plate.

[0010] Furthermore, a gear disk is fixedly connected to the bottom surface of the transmission disk, and a drive gear is provided on one side of the gear disk, with the gear disk and the drive gear meshing with each other.

[0011] Furthermore, a mounting bracket is fixedly installed on the top surface of the base plate, and a drive motor is fixedly installed on the top surface of the mounting bracket. The drive motor is connected to a drive gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting fixed blocks, the device can be used without stopping to change the fixed mold. The drive motor drives the drive gear to rotate, which in turn drives the gear plate and the transmission plate on the top surface to rotate synchronously. This allows the transmission groove to drive the transmission rod to move. Under the limiting effect of the through groove, the four stepped fixed blocks can move outward at the same time. This can quickly adapt to gears with different inner diameters, and the stepped design further expands the scope of application, greatly reducing downtime for mold changing and improving processing efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] See Figure 1-4 A gear drilling processing device includes a base plate 1, a gantry frame 2, and a drilling mechanism 3. A transmission box 9 is provided on the top surface of the base plate 1. A movable retaining block 10 is provided on the top surface of the transmission box 9. The retaining block 10 is generally stepped and the outer edge of the retaining block 10 is rounded. A through groove 11 is provided through the top surface of the transmission box 9. The bottom of the retaining block 10 is located in the through groove 11. A rotatable transmission disc 14 is installed on the bottom of the inner wall of the transmission box 9. A semi-circular transmission groove 15 is provided on the inner wall of the transmission disc 14. A movable transmission rod 16 is provided inside the transmission groove 15. The top end of the transmission rod 16 is fixedly connected to the through groove 11.

[0017] Furthermore, limiting grooves 12 are opened on both sides of the inner wall of the through groove 11, and limiting blocks 13 are fixedly installed on both sides of the bottom of the outer wall of the retaining block 10. The limiting blocks 13 are adapted to the limiting grooves 12 and in the initial state, the limiting blocks 13 are inside the limiting grooves 12. The specific number of retaining blocks 10 and through grooves 11 are four, and they are all distributed in a circular array.

[0018] By opening limiting grooves 12 on both sides of the outer wall of the through groove 11, and setting the limiting block 13 fixedly installed at the bottom of the outer wall of the retaining block 10 inside the limiting groove 12, the movement of the retaining block 10 is restricted, and it can only move in the horizontal direction. It will not easily detach from the device body, thus increasing the stability of the device operation.

[0019] Furthermore, two connecting blocks 7 are fixedly installed on the side wall of the gantry frame 2, arranged symmetrically. The transmission box 9 is fixedly connected between the two gantry frames 2 and does not directly contact the base plate 1. By setting the connecting block 7, the transmission box 9 can be kept out of direct contact with the base plate 1, making it convenient for the user to drive the transmission disc 14 and the gear disc 8 to rotate.

[0020] Furthermore, a gear disk 8 is fixedly connected to the bottom surface of the transmission disk 14, and a drive gear 6 is provided on one side of the gear disk 8. The gear disk 8 and the drive gear 6 mesh with each other.

[0021] By setting the gear 8 and the drive gear 6 to mesh with each other, the user can drive the gear 8 to rotate by rotating the drive gear 6.

[0022] In addition, a mounting bracket 4 is fixedly installed on the top surface of the base plate 1, and a drive motor 5 is fixedly installed on the top surface of the mounting bracket 4. The drive motor 5 is connected to the drive gear 6.

[0023] In practice, traditional rotary drilling devices typically use a special fixing mold to fix the gear or use external clamping to fix it. This means that when processing gears with different inner diameters, the device must frequently stop to change the corresponding fixing mold, and external clamping can damage the outside of the gear.

[0024] In this application, when a user needs to deal with gears of different inner diameters, the user can drive the drive gear 6 to rotate via the drive motor 5. During the rotation of the drive gear 6, the gear disk 8 will rotate. After the gear disk 8 rotates, the transmission disk 14 fixedly installed on its top surface will rotate synchronously. The transmission rod 16 is located in the transmission groove 15 opened on the top surface of the transmission disk 14. Therefore, the transmission rod 16 will be driven to move by the transmission groove 15 under the rotation of the transmission disk 14. The retaining block 10 fixedly connected to the top of the drive gear 6 via the through groove 11 is also restricted by the through groove 11. Therefore, under the joint restriction of the through groove 11 and the transmission groove 15, the four retaining blocks 10 will move outward along the through groove 11 at the same time, thereby achieving the fixation of gears of different inner diameters.

[0025] It should be noted that the retaining block 10 is stepped in shape, which further expands its applicability.

[0026] It should also be noted that during the reverse control process, the device can also clamp objects, allowing other parts without through holes in the middle position to be used in the device.

[0027] By setting the retaining blocks 10, the device can be used without stopping to change the fixed mold. The drive motor 5 drives the drive gear 6 to rotate, which drives the gear plate 8 and the transmission plate 14 on the top surface to rotate synchronously. This allows the transmission groove 15 to drive the transmission rod 16 to move. Under the limiting effect of the through groove 11, the four stepped retaining blocks 10 can move outward at the same time. This can quickly adapt to gears with different inner diameters, and the stepped design further expands the scope of application, greatly reducing downtime for mold changing and improving processing efficiency.

[0028] Working principle: Traditional rotary drilling devices usually use a special fixing mold to fix the gear or use external clamping to fix it. This means that when processing gears with different inner diameter specifications, the device must frequently stop to change the corresponding fixing mold, and external clamping will cause damage to the outside of the gear.

[0029] In this application, when a user needs to deal with gears of different inner diameters, the user can drive the drive gear 6 to rotate via the drive motor 5. During the rotation of the drive gear 6, the gear disk 8 will rotate. After the gear disk 8 rotates, the transmission disk 14 fixedly installed on its top surface will rotate synchronously. The transmission rod 16 is located in the transmission groove 15 opened on the top surface of the transmission disk 14. Therefore, the transmission rod 16 will be driven to move by the transmission groove 15 under the rotation of the transmission disk 14. The retaining block 10 fixedly connected to the top of the drive gear 6 via the through groove 11 is also restricted by the through groove 11. Therefore, under the joint restriction of the through groove 11 and the transmission groove 15, the four retaining blocks 10 will move outward along the through groove 11 at the same time, thereby achieving the fixation of gears of different inner diameters.

[0030] It should be noted that the retaining block 10 is stepped in shape, which further expands its applicability.

[0031] It should also be noted that during the reverse control process, the device can also clamp objects, allowing other parts without through holes in the middle position to be used in the device.

[0032] By setting the retaining blocks 10, the device can be used without stopping to change the fixed mold. The drive motor 5 drives the drive gear 6 to rotate, which drives the gear plate 8 and the transmission plate 14 on the top surface to rotate synchronously. This allows the transmission groove 15 to drive the transmission rod 16 to move. Under the limiting effect of the through groove 11, the four stepped retaining blocks 10 can move outward at the same time. This can quickly adapt to gears with different inner diameters, and the stepped design further expands the scope of application, greatly reducing downtime for mold changing and improving processing efficiency.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
