Description

Technical Field

[0001] This utility model belongs to the field of camshaft manufacturing technology, and in particular, it relates to a drilling device for camshaft manufacturing. Background Technology

[0002] The production and processing of camshafts requires the use of drilling equipment. However, existing drilling equipment is not convenient for adjusting the lateral drilling position of the camshaft, requiring manual adjustment of the drilling position and reducing the drilling efficiency of the camshaft.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN207840193U) for a drilling device for camshaft production. The device includes a base, a fixing plate and a fixing ring on top of the base, with the fixing ring located on one side of the fixing plate. Connecting blocks are provided on both sides of the base. A fixing box is provided on one side of the fixing plate, and a control panel is provided on the front surface of the fixing box. A power switch and an emergency stop button are provided on the front surface of the control panel, with the emergency stop button located on one side of the power switch. A support plate is provided on the other side of the fixing plate. This invention incorporates connecting blocks in an L-shape, with the vertical side fixed to the base by bolts and the horizontal side fixed to the worktable by bolts. This avoids the problem of the drilling machine shaking during drilling or accidental movement by the user, causing a significant deviation between the drill bit and the circular hole on the camshaft, resulting in drill bit breakage and potential injury to the user. However, this device does not consider adjusting the lateral drilling position of the camshaft, requiring manual adjustment and reducing the drilling efficiency of the camshaft. Utility Model Content

[0004] The purpose of this invention is to provide a drilling device for camshaft production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for camshaft production, comprising:

[0006] The processing table has fixed frames welded to both ends of the top. Limit rods are welded to the inner side walls of the fixed frames. Moving plates are slidably connected to the sides of the limit rods. The top and bottom surfaces of the moving plates are slidably connected to the inner walls of the fixed frames. Clamping assemblies for clamping camshafts are provided on the adjacent sides of the two moving plates. An L-shaped connecting plate is welded to the side of one of the moving plates away from the clamping assembly. The moving part of a linear motor is welded to the bottom surface of the connecting plate.

[0007] The camshaft production drilling head has a top surface connected to the output shaft of a rotary motor via a coupling. The fixed end of the rotary motor is detachably connected to a slide plate via bolts. The top surface of the slide plate is welded to the moving end of an electric push rod. The clamping assembly includes a placement plate and two mounting plates. The top two ends of the placement plate are welded to the two mounting plates, and the two sides of the placement plate are welded to the two moving plates. An electric push rod is embedded in the side of the mounting plate. The moving end of the electric push rod is welded to an L-shaped clamping plate for clamping and fixing the camshaft. The inner sidewalls of the two clamping plates are centrifugally arranged. The two sides of the clamping plates are rotatably connected to side plates via pins. The top surface of the side plates has a groove, and the inner wall of the groove is movably connected to a movable rod. An electric push rod is installed on the top surface of the clamping plate. The moving end of the electric push rod is welded to a horizontal plate, and the bottom two ends of the horizontal plate are welded to the two movable rods. Four equidistant support rods are welded to the bottom surface of the processing table.

[0008] Preferably, the fixed end of the linear motor is embedded in the top surface of the processing table, and a T-shaped slide rail is embedded in the side of the slide plate.

[0009] Preferably, an L-shaped support plate is welded to the side of the slide rail, and the inner wall of the support plate is slidably connected to the slide plate.

[0010] Preferably, the bottom surface of the support plate is welded to the processing table, and an electric push rod is embedded in the top surface of the support plate.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0012] This drilling equipment for camshaft production uses a rotary motor whose output shaft rotates to drive a drilling head. The rotating drilling head then drills the camshaft. An electric push rod provides power, causing its moving end to move a sliding plate along a guide rail. During transmission, the vertical position of the drilling head is adjusted. Since adjusting the lateral position of the camshaft during drilling is inconvenient and requires manual adjustment, reducing the drilling efficiency, a linear motor provides power. Its moving part moves a connecting plate, which then moves along the path of a limit rod. During transmission, the position of the camshaft, held and fixed by the clamping assembly, is adjusted, improving the drilling efficiency of the camshaft.

[0013] This drilling equipment for camshaft production places the camshaft on the top surface of the mounting plate. Two electric push rods provide power, causing the moving ends of the electric push rods to move the clamping plates laterally. As the two clamping plates move towards the center, they clamp and fix the camshaft. Directly clamping the camshaft laterally during drilling is prone to lateral wobbling and displacement. Two electric push rods provide power, causing the moving ends of the electric push rods to move the horizontal plate laterally. This causes the movable rod to rotate and move relative to the sliding groove of the side plate, allowing both side plates to rotate relative to the clamping plates. This provides auxiliary clamping of the camshaft, clamping and fixing it in another direction, thus improving the stability of the camshaft clamping and fixing. Attached Figure Description

[0025] To address the issue of inconvenient adjustment of the lateral drilling position of camshafts during use, which reduces drilling efficiency in camshaft production drilling equipment, please refer to [link to relevant documentation]. Figures 1 to 5 The structure of the device body includes:

[0026] A processing table 1 has fixed frames 2 welded to both ends of its top. A limit rod 3 is welded to the inner wall of the fixed frame 2. The fixed frame 2 provides support and fixation for the limit rod 3. A movable plate 4 is slidably connected to the side of the limit rod 3. A through groove is opened on the side of the movable plate 4. The inner wall of the through groove of the movable plate 4 is slidably connected to the limit rod 3, so that the movable plate 4 moves along the path of the limit rod 3. The top and bottom surfaces of the movable plate 4 are slidably connected to the inner wall of the fixed frame 2, which further enhances the lateral movement stability of the movable plate 4.

[0027] Two movable plates 4 are provided with clamping components 5 for clamping camshafts on adjacent sides. The camshafts are clamped and fixed by the clamping components 5. An L-shaped connecting plate 6 is welded to the side of one of the movable plates 4 away from the clamping components 5. The moving part of the linear motor 7 is welded to the bottom surface of the connecting plate 6. The linear motor 7 provides power so that the moving part of the linear motor 7 drives the connecting plate 6 to move during the movement. Under the connection provided by the connecting plate 6, the movable plate 4 moves down along the path of the limit rod 3. During the transmission process, the camshaft clamped and fixed by the clamping components 5 is adjusted to make lateral position adjustment to adapt to the drilling position requirements of the camshaft and improve the drilling efficiency of the drilling equipment for the camshaft.

[0028] A drilling head 13 is used for drilling camshafts. The top surface of the drilling head 13 is connected to the output shaft of a rotary motor 12 via a coupling. The rotary motor 12 provides power, causing the output shaft of the rotary motor 12 to rotate, thereby driving the drilling head 13 to rotate and providing conditions for drilling the camshaft. The fixed end of the rotary motor 12 is detachably connected to a slide plate 9 via bolts. The top surface of the slide plate 9 is welded with the moving end of an electric push rod 11. The moving end of the electric push rod 11 drives the slide plate 9 to move during the movement of the slide plate 9. During the transmission process, the vertical position of the drilling head 13 is adjusted so that the drilling head 13 moves to a specified height to drill the camshaft.

[0029] The fixed end of the linear motor 7 is embedded in the top surface of the processing table 1. The top surface of the processing table 1 has a groove. The inner wall of the groove of the processing table 1 is detachably connected to the fixed end of the linear motor 7 by bolts. The side of the slide plate 9 is embedded with a T-shaped slide rail 10, which allows the slide plate 9 to move along the path of the slide rail 10, thereby enhancing the vertical movement stability of the slide plate 9. An L-shaped support plate 8 is welded to the side of the slide rail 10. The inner wall of the support plate 8 is slidably connected to the slide plate 9. The bottom surface of the support plate 8 is welded to the processing table 1. The electric push rod 11 is embedded in the top surface of the support plate 8. The top surface of the support plate 8 has a through groove. The inner wall of the through groove of the support plate 8 is detachably connected to the fixed end of the electric push rod 11 by bolts.

[0030] The clamping assembly 5 includes a placement plate 15 and two mounting plates 16. The placement plate 15 is used to place the camshaft. The top two ends of the placement plate 15 are welded to the two mounting plates 16, and the two sides of the placement plate 15 are welded to the two movable plates 4, which facilitates the synchronous positional movement of the placement plate 15 and the two movable plates 4. An electric push rod 17 is embedded in the side of the mounting plate 16. A through groove is opened on the side of the mounting plate 16. The inner wall of the through groove of the mounting plate 16 is detachably connected to the fixed end of the electric push rod 17. An L-shaped clamping plate 18 for clamping and fixing the camshaft is welded to the movable end of the electric push rod 17, so that the two electric push rods 17 provide power and the two clamping plates 18 move centripetally during the transmission process, providing clamping and fixing function for the camshaft located on the top surface of the placement plate 15. The inner sidewalls of the two clamping plates 18 are centrifugally arranged, and the inner top wall of the clamping plate 18 is higher than the top surface of the mounting plate 16.

[0031] Side plates 22 are rotatably connected to both sides of the clamping plate 18 via pins, enabling relative rotation between one clamping plate 18 and the two side plates 22. A groove is formed on the top surface of the side plate 22, and a movable rod 21 is movably connected to the inner wall of the groove. An electric push rod 19 is mounted on the top surface of the clamping plate 18. The fixed end of the electric push rod 19 is detachably connected to the top surface of the clamping plate 18 via bolts. A horizontal plate 20 is welded to the moving end of the electric push rod 19, and the bottom ends of the horizontal plate 20 are welded to the two movable rods 21. Then, the moving end of the electric push rod 19 moves, driving the horizontal plate 20 to move, thereby realizing the relative rotation and movement of the two movable rods 21 along the sliding grooves of the two side plates 22. During the transmission process, the tilt angle between the two side plates 22 and the clamping plate 18 is adjusted so that the side plates 22 assist in clamping the camshaft from another direction, improving the clamping and fixing stability of the camshaft and preventing the camshaft from shaking and shifting during drilling. Four equidistant support rods 14 are welded to the bottom surface of the processing table 1.

[0032] Linear motor 7, electric actuator 11, rotary motor 12, electric actuator 2 17, and electric actuator 3 19 are all existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0033] Working principle

[0034] When using this drilling equipment for camshaft production, the user activates two electric push rods 17, causing the two clamping plates 18 to move towards the center and clamp the camshaft located on the top surface of the shelf 15. Activating two electric push rods 19 causes the moving end of the electric push rods 19 to move the horizontal plate 20, thereby enabling the movable rod 21 to rotate and move relative to the sliding groove of the side plate 22. This adjusts the tilt angle between the side plate 22 and the clamping plate 18, allowing for multi-directional clamping and fixation of the camshaft.

[0035] Start the electric push rod 11 and the rotary motor 12 to move the slide plate 9 along the path of the slide rail 10, so that the rotating drill head 13 can be moved to a specified height to drill the camshaft. Start the linear motor 7. During the movement of the linear motor 7, the connecting plate 6 is moved, so that the moving plate 4 moves along the path of the limit rod 3 and moves along the inner wall of the fixed frame 2. During the transmission, the lateral position of the camshaft clamped and fixed by the clamping component 5 is adjusted to adjust the drilling position of the camshaft.
