Problems solved by technology

At present, there are two ways to solve the black spot problem of the engine camshaft journal: one is to control the occurrence process, such as improving the support condition, replacing the high-efficiency cleaning agent and lubricating medium (such as oil cooling), increasing the cooling flushing pressure and cooling cleanliness (such as 2um filtration), and finally ensure that there is no black spot on the surface of the grinding journal; the other is to solve it by adding some links after the black spot is generated, such as deburring machine, polishing machine, automatic or manual cleaning, etc., but The above methods all have the problem of low efficiency

Embodiment 1

[0019] Such as figure 1 As shown, the device for automatically removing camshaft black spots in this embodiment includes at least two clamp arms 1 driven by a driving device to realize closing and opening, and an elastic telescopic mechanism 2 is installed on the opposite surface of the clamp arm 1, so The elastic expansion mechanism 2 is equipped with a polishing block 3 .

[0020] During the production process of the camshaft, under the drive of the driving device, the clamp arm 1 is used to drive the elastic expansion mechanism 2 and the polishing block 3 at the end to hold the journal or other parts of the camshaft tightly, and then the camshaft is rotated on the machine tool During the process, the camshaft can be automatically cleaned to remove the black spots on the camshaft. Due to the specially provided elastic telescopic mechanism 2, the influence of the radial movement on the polishing block 3 during the rotation of the camshaft can be eliminated, so that the polis...

Embodiment 2

[0025] Such as Figure 4 As shown, the difference from Embodiment 1 is that in the elastic telescopic mechanism of this embodiment, the body 21 and the clip arm 1 are provided with a slide rail 26 that cooperates with each other, and the body 21 is movably installed on the clip arm 1 through the slide rail 26 Above, the main body 21 can move relative to the clamp arm 1, so that when the camshaft rotates, the main body 21 can be synchronously driven to move along the slide rail 26, so as to ensure that the polishing block 3 is always attached to the camshaft.

[0026] Both sides of the body 21 are provided with return springs 27 , one end of the return spring 27 is connected and fixed to the body 21 , and the other end is connected and fixed to the clip arm 1 . The return spring 27 can apply a return force to the body 21 to urge the body 21 to move to a position close to the axis of the camshaft, so as to better promote the polishing block 3 to fit the camshaft.

Abstract

The invention provides a device for automatically removing black spots of a cam shaft. The device can high-efficiently solve the problem of black sports of a shaft neck of the cam shaft. The device comprises at least two clamp arms driven by a drive device so as to be closed and opened, wherein elastic flexible mechanisms are arranged on opposite faces of the clamp arms; a polishing compound is arranged on each elastic flexible mechanism. During a production process of the cam shaft, under the drive of the drive device, the elastic flexible mechanisms and the polishing compounds on end parts of the elastic flexible mechanisms are driven by the clamp arms so as to clamp the neck shaft or other parts of the cam shaft, so that when the cam shaft is rotated by a machine tool, the cam shaft can be automatically cleaned, and the black sports of the cam shaft are cleared. Due to the particular arrangement of the elastic flexible mechanisms, the influence of radial movement on the polishing compounds when the cam shaft is rotated can be eliminated, the polishing compounds are still fitted with the cam shaft, and the cleaning effect is ensured. According to the device, on the basis of existing resources and under the condition of lower cost input, the black sports of the cam shaft can be full-automatically cleared, and the device has excellent practicability.

Description

technical field [0001] The invention relates to a device for improving the surface quality of workpieces in machining, in particular to a device for automatically removing black spots on camshafts during camshaft production. Background technique [0002] The manufacture of key engine parts is a complex and precise process. In addition to formulating a reasonable and accurate processing technology, the technicians need to have high mechanical processing technology theory and practical problem-solving skills and other necessary factors, some in the processing process The production of the required auxiliary tools is also very important. At present, there are two ways to solve the black spot problem of the engine camshaft journal: one is to control the occurrence process, such as improving the support condition, replacing the high-efficiency cleaning agent and lubricating medium (such as oil cooling), increasing the cooling flushing pressure and cooling cleanliness (such as 2...
