Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically to a tooling for machining external cylindrical threaded holes in a cylinder. Background Technology

[0002] In the field of mechanical manufacturing, cylinder blocks are a common component widely used in various mechanical equipment. To meet the requirements for connection, installation, and specific functions of the cylinder block with other components, threaded holes are usually machined on the outer cylindrical surface of the cylinder block.

[0003] Currently, the traditional method for machining the outer cylindrical threaded holes of cylinders mainly relies on manual operation. Operators use simple clamps to fix the cylinder body and then use manual or semi-automatic drilling and tapping tools for machining. However, this traditional method has certain technical problems. On the one hand, manually fixing the cylinder body makes it difficult to ensure its positional accuracy and stability, easily leading to cylinder body wobbling and displacement during machining, resulting in problems such as positional deviations and dimensional errors in the threaded holes, seriously affecting machining quality. On the other hand, manually operating drilling and tapping tools is not only labor-intensive and inefficient, but also makes it difficult to guarantee the stability and consistency of the machining process. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a tooling for machining external cylindrical threaded holes in cylinders that not only facilitates drilling and tapping of cylinder bodies by workers, but also makes it convenient for workers to drill and tap holes on both sides of the cylinder body.

[0005] This utility model is achieved through the following technical solution: a tooling for machining the outer cylindrical threaded hole of a cylinder is provided, including a base and a sliding groove opened on the top of the base. A sliding plate is provided in the sliding groove, and a rotating groove is opened on the top of the sliding plate. A turntable is provided in the rotating groove, and a placement groove for fixing the cylinder is opened on the top of the turntable. Two clamping plates are provided in the sliding groove above the sliding plate. The two clamping plates are respectively located on the left and right sides of the turntable. One of the clamping plates has a reset mechanism on the side wall away from the turntable that is fixed to the inner side wall of the sliding groove and enables one of the clamping plates to move left and right. The other clamping plate has a driving mechanism on the side wall away from the turntable that is fixed to the top of the base and enables the other clamping plate to move left and right. A drilling and tapping device is provided on the top of the base on the side of one of the clamping plates away from the turntable.

[0006] In use, this utility model features a base and a sliding groove on the top of the base. A sliding plate is housed within the groove, and a rotating groove is formed on the top of the sliding plate. A turntable is housed within the rotating groove, and a placement groove for fixing a cylinder is formed on the top of the turntable. Two clamping plates are positioned above the sliding plate within the sliding groove, located on the left and right sides of the turntable. One clamping plate has a reset mechanism on its side wall away from the turntable, which is fixed to the inner side wall of the sliding groove. The other clamping plate has a drive mechanism on its side wall away from the turntable, which is fixed to the top of the base and allows the other clamping plate to move left and right. A groove is also provided on the top of the base, located on the side wall away from the turntable. The drilling and tapping device on one side of the turntable requires the cylinder to be placed in the slot on top of the turntable during use. This fixes the cylinder relative to the turntable. Then, the drive mechanism moves another clamping plate within a groove, causing it to move towards one of the clamping plates. This brings the other clamping plate into contact with the cylinder's sidewall facing the drive mechanism, causing the cylinder to move towards that clamping plate as well. Through the transmission between the slot and the turntable, the sliding plate moves within the groove towards that clamping plate as well, bringing one of the clamping plates into contact with the cylinder's sidewall away from the drive mechanism. This ensures that one of the clamping plates is in contact with the sidewall of the cylinder furthest from the drive mechanism. Under the action of the mechanism, the cylinder continues to move towards the drilling and tapping device within the groove, compressing the reset mechanism. This causes the side wall of the cylinder away from the drive mechanism to contact the drilling and tapping device, thus creating a hole in the side wall away from the drive mechanism. After the drilling and tapping device has completed creating the hole in the cylinder, the drive mechanism drives another clamping plate to move away from one of the clamping plates, causing the other clamping plate to return to its initial position and no longer contact the cylinder. At this point, because the reset mechanism loses the force moving away from the drive mechanism, it is no longer compressed and returns to its initial position, thereby causing one of the clamping plates to move away from the drilling and tapping device within the groove. The cylinder moves back to its initial position. At this point, one of the clamping plates is in contact with the side wall of the cylinder away from the drive mechanism. Therefore, during the movement, one of the clamping plates will also drive the cylinder to move away from the drilling and tapping device. Through the transmission of the placement groove and the turntable, the sliding plate will also move away from the drilling and tapping device in the groove. If you want to drill a hole on the other side of the cylinder, rotate the cylinder 180° so that it drives the turntable to rotate in the groove through the transmission of the placement groove. Repeat the above steps. This not only makes it convenient for the operator to drill and tap the cylinder, but also makes it convenient for the operator to drill and tap both sides of the cylinder.

[0007] Preferably, the reset mechanism includes a limiting rod fixedly connected to the side wall of one of the clamping plates away from the turntable, and a limiting hole opened on the inner side wall of the slide groove and adapted to the limiting rod. The limiting rod extends laterally into the limiting hole in the direction away from the turntable, and a first spring is sleeved on the limiting rod and fixedly connected to the side wall of one of the clamping plates away from the turntable and the inner side wall of the slide groove, respectively. The reset mechanism includes a limiting rod fixedly connected to the side wall of one of the clamping plates away from the turntable, and a limiting hole adapted to the limiting rod and opened on the inner side wall of the slide groove. The limiting rod extends laterally into the limiting hole in the direction away from the turntable. A first spring is sleeved on the limiting rod and fixedly connected to the side wall of one of the clamping plates away from the turntable and the inner side wall of the slide groove, respectively. When the device is in use, the limiting rod will move in the limiting hole towards the drilling and tapping device under the drive of one of the clamping plates, and compress the first spring. When the other clamping plate is no longer in contact with the cylinder, the first spring will extend back to its initial state because it loses the force in the direction away from the driving mechanism, and drive the limiting rod to move back to its initial position in the limiting hole in the direction away from the drilling and tapping device, thereby driving one of the clamping plates to move back to its initial position in the slide groove in the direction away from the drilling and tapping device.

[0008] Preferably, the driving mechanism includes a cylinder fixedly connected to the top of the base, and the output shaft end of the cylinder is fixedly connected to the side wall of another clamping plate away from the turntable. The driving mechanism includes a cylinder fixedly connected to the top of the base, and the output shaft end of the cylinder is fixedly connected to the side wall of another clamping plate away from the turntable. Using the cylinder, the operator can easily drive the other clamping plate to move left and right within the slide groove.

[0009] Preferably, the drilling and tapping device includes a rotary motor fixedly connected to the top of the base, and a combined drilling and tapping tap is coaxially fixed to the end of the output shaft of the rotary motor. The combination of the rotary motor and the combined drilling and tap allows operators to easily perform drilling and tapping on the cylinder.

[0010] Preferably, a second spring is provided on the side wall of the slide plate facing away from the cylinder, and is fixedly connected to the inner wall of the slide groove. By providing a second spring on the side wall of the slide plate facing away from the cylinder and fixedly connected to the inner wall of the slide groove, the slide plate can be returned to its initial position after the drilling and tapping device has finished drilling the hole in the cylinder.

[0011] The beneficial effects of this utility model are as follows: A base and a sliding groove are provided on the top of the base. A sliding plate is installed in the sliding groove, and a rotating groove is provided on the top of the sliding plate. A turntable is installed in the rotating groove, and a placement groove for fixing the cylinder body is provided on the top of the turntable. Two clamping plates are installed above the sliding plate in the sliding groove, and the two clamping plates are respectively located on the left and right sides of the turntable. One clamping plate has a reset mechanism on its side wall away from the turntable that is fixed to the inner side wall of the sliding groove and allows one clamping plate to move left and right. The other clamping plate has a drive mechanism on its side wall away from the turntable that is fixed to the top of the base and allows the other clamping plate to move left and right. A groove is provided on the top of the base where one of the clamping plates is located away from the turntable. The drilling and tapping device on one side of the turntable requires the cylinder to be placed in the slot on top of the turntable during use. This fixes the cylinder relative to the turntable. Then, the drive mechanism moves another clamping plate within a groove, causing it to move towards one of the clamping plates. This brings the other clamping plate into contact with the cylinder's sidewall facing the drive mechanism, causing the cylinder to move towards that clamping plate as well. Through the transmission between the slot and the turntable, the sliding plate moves within the groove towards that clamping plate as well, bringing one of the clamping plates into contact with the cylinder's sidewall away from the drive mechanism. This ensures that one of the clamping plates is in contact with the sidewall of the cylinder furthest from the drive mechanism. Under the action of the mechanism, the cylinder continues to move towards the drilling and tapping device within the groove, compressing the reset mechanism. This causes the side wall of the cylinder away from the drive mechanism to contact the drilling and tapping device, thus creating a hole in the side wall away from the drive mechanism. After the drilling and tapping device has completed creating the hole in the cylinder, the drive mechanism drives another clamping plate to move away from one of the clamping plates, causing the other clamping plate to return to its initial position and no longer contact the cylinder. At this point, because the reset mechanism loses the force moving away from the drive mechanism, it is no longer compressed and returns to its initial position, thereby causing one of the clamping plates to move away from the drilling and tapping device within the groove. The cylinder moves back to its initial position. At this point, one of the clamping plates is in contact with the side wall of the cylinder away from the drive mechanism. Therefore, during the movement, one of the clamping plates will also drive the cylinder to move away from the drilling and tapping device. Through the transmission of the placement groove and the turntable, the sliding plate will also move away from the drilling and tapping device in the groove. If you want to drill a hole on the other side of the cylinder, rotate the cylinder 180° so that it drives the turntable to rotate in the groove through the transmission of the placement groove. Repeat the above steps. This not only makes it convenient for the operator to drill and tap the cylinder, but also makes it convenient for the operator to drill and tap both sides of the cylinder.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figures 1-4 The present invention discloses a tooling for machining the outer cylindrical threaded hole of a cylinder body, comprising a base 5 and a sliding groove 8 formed on the top of the base 5. A sliding plate 13 is provided in the sliding groove 8, and a rotating groove 9 is formed on the top of the sliding plate 13. A turntable 12 is provided in the rotating groove 9, and a placement groove 11 for fixing the cylinder body is formed on the top of the turntable 12. Two clamping plates 3 are provided in the sliding groove 8 above the sliding plate 13. The two clamping plates 3 are respectively located on the left and right sides of the turntable 12. One clamping plate 3 has a reset mechanism on its side wall away from the turntable 12 that is fixed to the inner side wall of the sliding groove 8 and allows one clamping plate 3 to move left and right. The other clamping plate 3 has a driving mechanism on its side wall away from the turntable 12 that is fixed to the top of the base 5 and allows the other clamping plate 3 to move left and right. A drilling and tapping device is provided on the top of the base 5 on the side of one of the clamping plates 3 away from the turntable 12.

[0020] The reset mechanism includes a limiting rod 6 fixedly connected to the side wall of one of the clamping plates 3 away from the turntable 12, and a limiting hole 14 opened on the inner side wall of the slide groove 8 and adapted to the limiting rod 6. The limiting rod 6 extends laterally into the limiting hole 14 in the direction away from the turntable 12. A first spring 7 is sleeved on the limiting rod 6 and fixedly connected to the side wall of one of the clamping plates 3 away from the turntable 12 and the inner side wall of the slide groove 8, respectively. When the device is in use, the limiting rod 6 will move in the limiting hole 14 towards the drilling and tapping device under the drive of one of the clamping plates 3, and compress the first spring 7. When the other clamping plate 3 is no longer in contact with the cylinder, the first spring 7 will extend back to the initial state because it loses the force in the direction away from the driving mechanism, and drive the limiting rod 6 to move back to the initial position in the limiting hole 14 in the direction away from the drilling and tapping device, thereby driving one of the clamping plates 3 to move back to the initial position in the slide groove 8 in the direction away from the drilling and tapping device. The driving mechanism includes a cylinder 4 fixedly connected to the top of the base 5. The output shaft end of the cylinder 4 is fixedly connected to the side wall of another clamping plate 3 away from the turntable 12. The cylinder 4 allows the operator to easily drive the other clamping plate 3 to move left and right within the slide groove 8. The drilling and tapping device includes a rotary motor 1 fixedly connected to the top of the base 5. The output shaft end of the rotary motor 1 is coaxially fixedly connected to a drilling and tapping composite tap 2. The rotary motor 1 and the drilling and tapping composite tap 2 allow the operator to easily drill and tap on the cylinder. A second spring 10 is provided on the side wall of the slide plate 13 facing away from the cylinder 4 and fixedly connected to the inner side wall of the slide groove 8. The second spring 10 allows the slide plate 13 to return to its initial position after the drilling and tapping device has drilled a hole in the cylinder.

[0021] Combined with appendix Figure 1-4The method of using this utility model is as follows: First, the cylinder body needs to be placed in the placement groove 11 on the top of the turntable 12 to fix the cylinder body relative to the turntable 12. Then, the rotating motor 1 is turned on to drive the drilling and tapping composite tap 2 to rotate. Then, the cylinder 4 is turned on to extend the piston rod of the cylinder 4, driving the other clamping plate 3 to move in the sliding groove 8 toward one of the clamping plates 3. This causes the other clamping plate 3 to abut against the side wall of the cylinder body facing the cylinder 4, thereby causing the cylinder body to move toward one of the clamping plates 3 as well. Driven by the placement groove 11 and the turntable 12, the slide plate 13 moves within the slide groove 8 towards one of the clamping plates 3, compressing the second spring 10. This causes one of the clamping plates 3 to abut against the side wall of the cylinder body away from the cylinder 4. Under the push of the cylinder 4, one of the clamping plates 3 continues to move within the slide groove 8 towards the drilling and tapping device. This causes the limiting rod 6, driven by one of the clamping plates 3, to move within the limiting hole 14 towards the drilling and tapping device, compressing the first spring 7. This causes the side wall of the cylinder body away from the cylinder 4 to rotate... The drilling and tapping device contacts the cylinder body using a combined tap 2, thereby creating a hole on the side wall away from the cylinder 4. After the drilling and tapping device has created the hole, the piston rod of the cylinder 4 is retracted by controlling the cylinder 4, causing the other clamping plate 3 to move away from one of the clamping plates 3. This returns the other clamping plate 3 to its initial position, no longer contacting the cylinder body. At this point, the first spring 7 loses its force in the direction away from the cylinder 4, and extends back to its initial state, causing the limiting rod 6 to move away from the drilling and tapping device within the limiting hole 14. Move back to the initial position, thereby causing one of the clamping plates 3 to move away from the drilling and tapping device in the slide groove 8 and also return to the initial position. At this time, since the second spring 10 also loses the force in the direction away from the cylinder 4, the second spring 10 will extend back to the initial state and cause the slide plate 13 to move away from the drilling and tapping device in the slide groove 8 and return to the initial position. If you want to drill a hole on the other side of the cylinder, rotate the cylinder 180° so that it drives the turntable 12 to rotate in the rotating groove 9 through the transmission of the placement groove 11, and repeat the above steps.
