Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for camshaft processing, in particular to a rough milling auxiliary device for camshafts. Background Art

[0002] In the modern automotive and machinery manufacturing industries, the camshaft is a key component of power systems such as engines. The rough milling of the camshaft is an important link in the camshaft processing process, which mainly involves the preliminary processing of the preliminarily formed camshaft blank to remove excess material and make its shape and dimensions close to the final design requirements.

[0003] During the traditional processing and grinding of camshafts, a clamping mechanism fixed at both ends is generally used to stabilize the camshaft to ensure the smooth progress of the processing. When the processing and grinding device applies forces at different parts of the camshaft, it is difficult to achieve uniform stress on the entire camshaft only by fixing at both ends. Especially when performing fine processing on local areas such as cams or journal necks, due to the force application point being far from the fixed end, it is easy to cause stress concentration in local areas of the camshaft, resulting in deformation or distortion, seriously affecting the quality of the camshaft, aggravating tool wear, reducing processing efficiency, and even causing unnecessary damage to the processing equipment. Summary of the Utility Model

[0004] In order to solve the technical problems caused by the existing uneven stress, the utility model provides a rough milling auxiliary device for camshafts.

[0005] The technical solution of the utility model is realized through the following scheme: a rough milling auxiliary device for camshafts, including a processing table, a transverse movement clamping assembly, and a support table. Oppositely arranged fixed disks are installed on the top surface of the processing table. A support table is installed on the top surface of the processing table, and the support table is located on one side of the fixed disks. The transverse movement clamping assembly is movably installed on the support table through a longitudinal movement lead screw. A cleaning device is installed between the support table and the processing table, and a waste drawer is slidably provided on one side of the processing table away from the support table.

[0006] Through the above technical scheme, through the transverse movement clamping assembly, dynamic support and clamping are provided at different positions of the camshaft, effectively solving the problem of uneven stress on the camshaft during processing in the traditional clamping method with both ends fixed, thereby dispersing the stress and avoiding deformation or distortion caused by local stress concentration. The transverse movement clamping assembly is movably installed through the longitudinal movement lead screw, effectively avoiding the obstruction of the transverse movement clamping assembly to the installation and disassembly of the camshaft. The cleaning device installed between the processing table and the support table and the slidable waste drawer facilitate the timely cleaning of the chips and waste generated during processing and keep the working area clean.

[0007] Preferably, the transverse translation and clamping assembly includes an auxiliary pedestal, a clamping device, and a transverse translation lead screw assembly. The transverse translation lead screw assembly is installed on one side of the auxiliary pedestal close to the fixed disk. The clamping device is installed on the movable seat of the transverse translation lead screw assembly. The auxiliary pedestal is connected to the support pedestal through a longitudinal translation lead screw.

[0008] Preferably, the clamping device includes clamping arms, a servo motor, and a double-headed threaded rod. The double-headed threaded rod is installed on the movable seat. Corresponding clamping arms are installed on the double-headed threaded rod. A number of rollers are installed inside the clamping arms. The servo motor drives the double-headed threaded rod to drive the two clamping arms to move relatively.

[0009] Through the above technical solutions, the combined use of the transverse translation lead screw assembly and the longitudinal translation lead screw enables the clamping device to move flexibly in both the horizontal and vertical directions, so as to more accurately locate different machining areas of the camshaft. The servo motor drives the double-headed threaded rod to drive the two clamping arms to move relatively for clamping, ensuring the stability and uniform force during the machining process. The uniform force situation reduces the vibration and impact during the machining process, reduces the wear of the cutting tool and the machining equipment, the rollers effectively reduce the friction between the clamping arms and the camshaft, reduce the damage to the surface of the camshaft, and improve the adaptability to camshafts of different specifications.

[0010] Preferably, the cleaning device includes a pushing electric cylinder and a cleaning brush. The cleaning brush is installed at the telescopic end of the pushing electric cylinder. The pushing electric cylinder is installed on the machining table.

[0011] Preferably, a through hole adapted to the cleaning brush is opened on the support pedestal.

[0012] Preferably, a waste collection port is opened on the machining table. The waste collection port is communicated with a waste drawer.

[0013] Through the above technical solutions, the through hole opened on the support pedestal and adapted to the cleaning brush enables the cleaning brush to smoothly pass through the support pedestal and push the waste into the waste drawer, realizing the centralized collection and treatment of the waste. When the cleaning brush is stored, it closes tightly to form a seal to prevent waste from entering the cleaning blind area.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. The utility model provides dynamic support and clamping at different positions of the camshaft through the transverse translation clamping assembly, effectively solving the problem of uneven stress on the camshaft during the machining process under the traditional fixed clamping method at both ends, thereby dispersing the stress and avoiding deformation or distortion caused by local stress concentration. The transverse translation clamping assembly is movably installed through the longitudinal translation lead screw, effectively avoiding the obstruction of the transverse translation clamping assembly to the installation and disassembly of the camshaft. The cleaning device and the pull-out waste drawer installed between the machining table and the support table facilitate the timely cleaning of chips and waste generated during the machining process, keeping the working area clean and tidy.

[0016] 2. The combined use of the transverse translation lead screw assembly and the longitudinal translation lead screw enables the clamping device to move flexibly in both horizontal and vertical directions, so as to more accurately locate different machining areas of the camshaft. The servo motor drives the double-headed threaded rod to drive the two clamping arms to perform relative movement for clamping, ensuring the stability and uniform stress during the machining process. The uniform stress situation reduces the vibration and impact during the machining process, reduces the wear of the cutting tool and the machining equipment, and the rollers effectively reduce the friction between the clamping arm and the camshaft, reduce the damage to the surface of the camshaft, and improve the adaptability to camshafts of different specifications.

[0017] 3. The through holes opened on the support table and adapted to the cleaning brush enable the cleaning brush to smoothly pass through the support table and push the waste into the waste drawer, realizing the centralized collection and treatment of waste. When the cleaning brush is stored, it closes tightly to form a seal to prevent waste from entering the cleaning blind area. Description of the Drawings

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification. The present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] A rough milling auxiliary device for a camshaft, as Figures 1 - 5 shown, includes a processing table 1, a transverse movement clamping assembly 2 and a support table 3. Oppositely arranged fixed disks are installed on the top surface of the processing table 1. A support table 3 is installed on the top surface of the processing table 1. The support table 3 is located on one side of the fixed disks. The transverse movement clamping assembly 2 is movably installed on the support table 3 through a longitudinal movement lead screw 4. A cleaning device 5 is installed between the support table 3 and the processing table 1. The support table 3 is integrally concave and is buckled on the processing table 1. Mounting holes are opened on the support legs on both sides of the support table 3. A lead screw and a limit slide rod are respectively installed in the two mounting holes to form the longitudinal movement lead screw 4, which drives the transverse movement clamping assembly 2 to perform longitudinal movement, so that the clamping device 22 is far away from the camshaft blank. The cleaning device 5 is installed on the processing table 1. The support table 3 is buckled to shield the cleaning device 5, cleverly protecting the cleaning device 5 from being polluted by external waste materials. Driven by the longitudinal movement lead screw 4, the transverse movement clamping assembly 2 can easily perform longitudinal movement, so that when the camshaft blank is processed, installed or disassembled, the position can be quickly adjusted to avoid hindering the operation and improve the operation efficiency. The transverse movement clamping assembly 2 can perform multi-directional adjustments of longitudinal and transverse movements, so as to realize effective clamping and positioning of the camshaft blank. A waste drawer 6 is slidably provided on one side of the processing table 1 away from the support table 3. A waste collection port is opened on the processing table 1. The waste collection port is communicated with the waste drawer 6, which is convenient for centralized treatment and recycling. The overall length of the waste collection port is slightly longer than the length of the two opposite fixed disks. An opening corresponding to the cleaning device 5 is opened on the support table 3, which is convenient for the cleaning device 5 to extend the cleaning brush 52 to push the waste into the waste collection port for tabletop cleaning.

[0027] The transverse movement and clamping assembly 2 includes an auxiliary pedestal 21, a clamping device 22 and a transverse movement lead screw assembly 23. The transverse movement lead screw assembly 23 is installed on one side of the auxiliary pedestal 21 close to the fixed disk. The clamping device 22 is installed on the movable seat of the transverse movement lead screw assembly 23. The auxiliary pedestal 21 is connected to the support pedestal 3 through a longitudinal movement lead screw 4. A slider adapted to the longitudinal movement lead screw 4 is fixedly installed on the bottom surface of the auxiliary pedestal 21. The auxiliary pedestal 21 is in the shape of a cuboid, and an installation hole is opened on one side close to the fixed disk. The transverse movement lead screw assembly 23 is arranged in the installation hole. The clamping device 22 moves transversely on the auxiliary pedestal 21, and the auxiliary pedestal 21 moves longitudinally on the support pedestal 3, so as to adjust flexibly, avoid bumping against the blank of the camshaft, and uniformly support the blank of the camshaft.

[0028] The clamping device 22 includes clamping arms 221, a servo motor 222 and a double-headed threaded rod 223. The double-headed threaded rod 223 is installed on the movable seat. Corresponding clamping arms 221 are installed on the double-headed threaded rod 223. A number of rollers 7 are installed in the clamping arms 221. The servo motor 222 drives the double-headed threaded rod 223 to drive the two clamping arms 221 to move relatively. The clamping arms 221 are arranged oppositely up and down to clamp the blank of the camshaft. The outer shell of the clamping arm 221 is in the shape of an "L", and an arc groove is opened at the corner to facilitate clamping the blank. The internal rollers 7 are also distributed in an "L" shape, which not only reduces the friction between the clamping arm 221 and the blank of the camshaft, but also reduces the heat and wear generated by the friction, quickly adapts to the change of the rotation speed of the blank of the camshaft, and improves the safety and stability of the clamping and supporting process. A "C"-shaped support is opened on the movable seat of the transverse movement lead screw assembly 23, and the double-headed threaded rod 223 is installed in the "C"-shaped support. The servo motor 222 is installed on the outer shell of the "C"-shaped support for driving. An isolation soft rubber plate is installed in the middle of the double-headed threaded rod 223 to prevent the upper and lower clamping arms 221 from exceeding the movement range and colliding and damaging. The servo motor 222 drives the double-headed threaded rod 223, which can accurately control the relative movement of the two clamping arms 221 to ensure that the clamping force on the blank of the camshaft is moderate and uniform.

[0029] The cleaning device 5 includes a pushing electric cylinder 51 and a cleaning brush 52. The cleaning brush 52 is installed at the telescopic end of the pushing electric cylinder 51. The pushing electric cylinder 51 is installed on the processing table 1. The number of the pushing electric cylinders 51 is three, and they are linearly arranged. The cleaning brush 52 is connected to the telescopic ends of the three pushing electric cylinders 51 to provide stable thrust, reducing the need for manual cleaning. A through hole adapted to the cleaning brush 52 is opened on the support pedestal 3. The cleaning brush 52 is closely fitted with the through hole on the support pedestal 3 to form a seal when the cleaning brush 52 is retracted, effectively preventing waste or debris generated during the processing from entering, avoiding incomplete cleaning, and preventing waste accumulation from causing wear to the equipment.

[0030] Working principle: Start the longitudinal movement lead screw 4 to make the transverse movement clamping assembly 2 move longitudinally away from the fixed disk. Further, the staff clamp the blank between the two fixed disks and drive it to rotate by the motor. At this time, the clamping device 22 in the transverse movement clamping assembly 2 is driven by the transverse movement lead screw assembly 23 to move transversely until it reaches the appropriate position. Further, the transverse movement clamping assembly 2 is driven by the longitudinal movement lead screw 4 to return. After returning, the servo motor 222 drives the double-headed threaded rod 223 to drive the two oppositely arranged clamping arms 221 up and down to clamp the blank.

[0031] When the rough milling is completed, three pushing electric cylinders 51 push the cleaning brush 52 to clean the table surface of the processing table 1 and push the waste into the waste drawer 6 to complete the collection.
