Description

Technical Field

[0001] The utility model relates to the field of parts cleaning, in particular to an automatic wiping device for a central hole at the end of a camshaft. Background Art

[0002] The center holes at both ends of the camshaft are process holes used to determine the center of the workpiece, and they play an important role in the field of mechanical engineering. As the positioning reference of the camshaft, the center hole is almost always used for positioning and driving in subsequent CNC lathes, drilling and tapping centers, and grinders to ensure the accurate position and precision of the camshaft during processing. During the processing, the center hole bears the deadweight and cutting force of the workpiece, which will cause grinding to the center hole. During the grinding process, due to the presence of a large amount of oil in the chip fluid, the oil will adhere to the surface of the center hole of the workpiece. This part of the oil is difficult to remove by normal equipment cleaning. At present, it is mainly cleaned by manual wiping with a rag, which is inefficient and has the quality risk of missed wiping, which can easily lead to unqualified final cleanliness of the product. Utility Model Content

[0003] In order to overcome the disadvantages that the oil stain in the center hole of the existing camshaft is difficult to remove, the technical problem to be solved by the utility model is to provide an automatic wiping device for the center hole of the end of the camshaft which can improve the wiping efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Furthermore, the rotary power head is a motor.

[0007] Furthermore, the rotary power head is a pneumatic motor.

[0008] Furthermore, the wiping head is of a conical structure and is detachably connected to the rotating shaft of the rotary power head.

[0009] Furthermore, the wiping head is a wool felt, a copper brush or a nylon brush.

[0010] Furthermore, the driving mechanism includes a support frame, and a vertical lifting rod and a horizontal telescopic rod controlled by a controller. A slide rail is provided on the top of the support frame, and the length direction of the slide rail is consistent with the axial direction of the camshaft placed on the support seat. The fixed seat of the vertical lifting rod is slidably set on the slide rail and slides along the slide rail under the drive of the horizontal telescopic rod. The rotary power head is set on the lifting end of the lower end of the vertical lifting rod, and the axis of the rotary power head and the axis of the camshaft are located in the same vertical plane.

[0011] Furthermore, the vertical lifting rod is a linear motor, and the horizontal telescopic rod is a hydraulic rod or a pneumatic rod.

[0012] The beneficial effects of the utility model are as follows: a wiping head is arranged on the rotating shaft of the rotating power head, and the wiping head is connected to the cleaning liquid delivery mechanism by an infusion tube to form a wiping main body; driven by the driving mechanism, the wiping head can simultaneously perform rotational wiping and cleaning liquid flushing on the center hole at the end of the camshaft, thereby ensuring the quality of oil cleaning and realizing automatic wiping of the center hole at the end of the camshaft, reducing the labor intensity of workers and improving the wiping efficiency.

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0017] like Figure 1As shown, the utility model provides an automatic wiping device for the center hole of the end of the camshaft, comprising a support platform 1, a support seat 2 and a rotary power head 3 arranged on the support platform 1, wherein the rotary power head 3 is arranged on the support seat 2 through a driving mechanism 4, and the rotating shaft of the rotary power head 3 is a hollow structure, and a wiping head 31 is arranged at one end of the rotating shaft close to the support seat 2, and the other end is connected to the cleaning liquid delivery mechanism through an infusion tube 32, and the rotary power head 3 is coaxially arranged with the camshaft 5 placed on the support seat 2 under the control of the driving mechanism 4, and can move along the axial direction of the camshaft 5, so as to realize the automatic wiping of the center hole of the end of the camshaft 5 by the wiping head 31. The rotary power head 3 can drive the wiping head 31 to rotate, so as to wipe the center hole of the end of the camshaft 5. The cleaning liquid delivery mechanism can spray the cleaning liquid to the wiping head 31 or directly into the center hole through the infusion tube 32 through a syringe pump and other equipment, so as to facilitate the wiping head 31 to remove the oil stains. The driving mechanism 4 is mainly used to drive the rotary power head 3 to move, so that the wiping head 31 is close to or away from the end of the cam shaft 5, so as to wipe and separate the wiping head 31 from the center hole of the cam shaft 5. Because the rotary power head 3 needs to move during operation, in order to avoid interference, the infusion tube 32 can be a hose structure as a whole, or another hose can be used to connect the infusion tube 32 and the rotating shaft of the rotary power head 3.

[0018] In addition, in order to realize automatic control, a controller is required to control the operation of the driving mechanism 4, the rotary power head 3 and the cleaning liquid delivery mechanism. The control process mainly includes the following steps: first, the wiping head 31 is aligned with the camshaft 5 by using the driving mechanism 4, and then the rotary power head 3 drives the wiping head 31 to rotate, and the driving mechanism 4 drives the wiping head 31 to move to a position in contact with the center hole of the camshaft 5, and then the cleaning liquid delivery mechanism sprays the cleaning liquid into the center hole, and finally the wiping head 31 continues to rotate for a certain period of time and then disengages from the camshaft 5, so as to realize the automatic wiping of the center hole of the camshaft 5. Among them, the movement of the driving mechanism 4 can be controlled by setting a sensor or accurately controlling the moving distance. The software part of the entire control structure is easy to implement, and the utility model mainly lies in the hardware design.

[0019] As for the rotary power head 3, as long as it can drive the rotating shaft to rotate, a common motor or a pneumatic motor can be used. Since the rotating shaft needs to be set as a hollow structure, a pneumatic motor is preferred, and the modification cost of the motor is relatively high.

[0020] In order to make the wiping head 31 contact the center hole better, the wiping head 31 can be set to a conical structure. Since the shapes and sizes of the center holes of different camshafts 5 are different, the wiping head 31 and the rotating shaft of the rotary power head 3 can be set to a detachable connection form, so that different wiping heads 31 can be replaced according to different needs. Specifically, the wiping head 31 can be a wool felt, a copper brush or a nylon brush, etc., which can be reasonably selected according to the oil pollution situation.

[0021] As for the driving mechanism 4, the preferred solution of the utility model is that the driving mechanism 4 includes a support frame 41, and a vertical lifting rod 42 and a horizontal telescopic rod 43 controlled by a controller, a slide rail 44 is provided on the top of the support frame 41, and the length direction of the slide rail 44 is consistent with the axis direction of the cam shaft 5 placed on the support seat 2, the fixed seat 45 of the vertical lifting rod 42 is slidably set on the slide rail 44, and slides along the slide rail 44 driven by the horizontal telescopic rod 43, the rotary power head 3 is set on the lifting end of the lower end of the vertical lifting rod 42, and the axis of the rotary power head 3 and the axis of the cam shaft 5 are located in the same vertical plane. Specifically, the vertical lifting rod 42 can use a linear motor, and the horizontal telescopic rod 43 can use a hydraulic rod or a pneumatic rod. When cleaning the camshaft 5 of the same model, the height of the rotating power head 3 does not need to be adjusted frequently. The wiping head 31 can be adjusted once to align with the center hole of the camshaft 5 through the vertical lifting rod 42. Subsequently, it is only necessary to control the horizontal telescopic rod 43 to extend or shorten a specific distance to make the wiping head 31 contact or disengage with the center hole. The control is simple and the operation is convenient.

[0022] The utility model forms a wiping body by arranging a wiping head 31 on the rotating shaft of the rotating power head 3, and connecting the wiping head 31 with a cleaning liquid delivery mechanism by means of an infusion tube 32. Driven by the driving mechanism 4, the wiping head 31 can simultaneously perform rotational wiping and cleaning liquid flushing on the center hole at the end of the camshaft 5, thereby ensuring the quality of cleaning oil stains and realizing automatic wiping of the center hole at the end of the camshaft 5, reducing the labor intensity of workers, improving the wiping efficiency, and having good practicality and application prospects.
