To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

As shown in fig. 2 to 11, the embodiment of the present invention discloses a surface processing apparatus for processing an end surface 301 of a workpiece, for example, milling the end surface 301 of the workpiece or grinding the end surface 301 of the workpiece. This face processingequipment includes: a holder 10, a columnar member 100, a damping mechanism 50, and a machining tool 200.

As shown in fig. 2 and 3, the holder 10 has a mounting side surface on which screw holes 11 are arranged, and the holder 10 is fixed to an external device, which may be a robot of an industrial robot or a moving member on a linear guide having two feeding directions, by passing fasteners through the screw holes 11, and the external device is configured to move the holder in a linear motion reciprocating on a plane to drive the processing tool 200 of the surface processing apparatus to process the end surface 301 of the workpiece. The holder 10 is provided with a vertically penetrating mounting hole.

The columnar member 100 is inserted into the mounting hole of the holder 10, and the machining tool 200 is attached to the lower end of the columnar member 100. For example, as shown in fig. 5 and 7, the processing tool 200 is a grinding tool 300, the grinding tool 300 includes two driving wheels, an abrasive cloth sleeved on the two driving wheels, and a motor 201 for driving one of the driving wheels to rotate so as to move the abrasive cloth, and the abrasive cloth contacts with an end surface 301 of the workpiece with a certain pressure (or contact force) along with the driving wheels to grind the end surface 301 of the workpiece; of course, the machining tool 200 may be a milling cutter that contacts the workpiece with a certain pressure, in this case, the inside of the columnar member 100 may be used to fix a motor, an output shaft of which protrudes out of a lower end of the columnar member 100, the milling cutter being connected to the output shaft, and the milling cutter being driven by the motor to mill the end surface 301 of the workpiece by rotating and reciprocating linear motion along with the holder 10, or: the column member 100 itself is a column-shaped motor that drives the rotation of the milling cutter.

In the present invention, the columnar member 100 is pivotally connected to the holder 10 by the pin shaft 30, and as shown in fig. 5, the pivot center O of the columnar member 100 coincides with the direction in which the holder 10 linearly moves with the external device (i.e., the linear traveling direction of the processing tool 200), which enables the columnar member 100 and the processing tool 200 described above to swing about the pivot center O in the direction perpendicular to the linear movement (the linear traveling direction of the processing tool 200) (or, in other words, the columnar member 100 and the processing tool 200 to swing on a plane perpendicular to the linear movement direction), as shown in fig. 7.

In this way, if the machining tool 200 is inclined with respect to the end surface 301 of the workpiece on a plane perpendicular to the movement direction thereof, as shown in fig. 10 and 11, after the external equipment drives the surface machining device to move down and the machining tool 200 contacts the end surface 301 of the tool 300, the columnar member 100 can correct the machining tool 200 from the inclined state to a state matching the end surface 301 of the workpiece by swinging, so that the machining tool 200 does not cause the end surface 301 to have the defect of the multiple slopes as described in the background art when machining the end surface 301 of the workpiece.

The damping mechanism 50 serves to provide resistance to the columnar member 100 against swinging about the pivot center O.

The function of the damping mechanism 50 should be understood as: without the damping mechanism 50, when the processing tool 200 contacts the end surface 301 of the workpiece, the processing tool 200 may move laterally on a plane perpendicular to the linear motion, and the contact between the processing tool 200 and the end surface 301 may be unstable, which may cause the processing process to be unstable for the end surface 301, i.e., without the damping mechanism 50, the cylindrical member 100 may cause the processing tool 200 to be in an unstable free state.

By adding the damping mechanism 50, the resistance for restricting the swing of the columnar member 100 can be applied to the columnar member 100, so that a certain rigidity is formed between the columnar member 100 and the holder 10, which can restrict the lateral movement of the machining tool 200 during the reciprocating linear motion to a certain extent, and can keep the machining tool 200 in stable contact with the end surface 301 of the workpiece all the time during the machining process.

The manner in which the damping mechanism 50 provides the impedance may be varied, for example, the damping mechanism 50 is configured to: a force resisting the swing of the columnar member 100 about the pivot center O is directly applied to the columnar member 100.

The type of force provided by the damping mechanism 50 may be various, for example, the damping mechanism 50 is configured to: the columnar member 100 is urged by a spring, and at this time, a force against the swing of the columnar member 100 is provided by an elastic force of the spring.

However, when resistance is provided to the columnar member 100 by a spring (or when a force is applied to the columnar member 100 by a spring), the resistance provided to the columnar member 100 cannot be adjusted because the force of the spring to the columnar member 100 cannot be adjusted (unless the spring is replaced or the amount of compression of the spring is changed), and thus the rigidity between the columnar member 100 and the holder 10 cannot be adjusted.

In some embodiments:

as shown in fig. 3, 5 and 6, the dough processing device further comprises a ring body 20 and a sleeve body 40. The ring body 20 is disposed in the mounting hole of the holder 10 and sleeved outside the cylindrical component 100, the pin 30 extends into the ring body 20 from the holder 10, a gasket 32 is disposed between the holder 10 and the tail of the pin 30, a copper sleeve 31 is disposed between the head of the pin 30 and the ring body 20, and the pin 30 and the holder 10 form a threaded connection to limit the pin 30 from being removed from the holder 10.

As shown in fig. 3 and 6, the sheath 40 covers the cylindrical member 100, an arc-shaped notch is formed at a lower end of the sheath 40 along a circumferential direction, an arc-shaped locking lath 42 is disposed at the arc-shaped notch, and the arc-shaped locking lath 42 is connected to the sheath 40 by a bolt to tightly cover the cylindrical member 100 by screwing the bolt, so that the sheath 40 and the cylindrical member 100 form a fixed connection.

As shown in fig. 6 to 8, a step surface 43 is formed at the middle part of the sleeve body 40, and the ring body 20 is sleeved on the sleeve body 40 above the step surface 43; the upper end of the sleeve body 40 is provided with a shaft retaining ring 41, the shaft retaining ring 41 is lapped on the upper end of the ring body 20, specifically, as shown in fig. 8, annular grooves are formed at the upper end and the lower end of the inner hole of the ring body 20, the damping ring 21 is arranged in the annular grooves, and the shaft retaining ring 41 is lapped on the damping ring 21 above the annular grooves. Thus, the ring body 20, the sleeve body 40 and the cylindrical component 100 can swing synchronously, and when the sleeve body 40 is overlapped on the damping ring 21 by the shaft retainer ring 41, the sleeve body 40 can float slightly relative to the ring body 20, and the sleeve body 40 can be effectively prevented from generating serious impact with the ring body 20 when the sleeve body 40 floats slightly due to the existence of the damping ring 21.

In the above embodiments, the damping mechanism 50 is used to apply force to the upper end of the ring body 20 at positions on both sides of the pivot center O for providing resistance.

In the above embodiments, the damping mechanism 50 may be configured as follows:

as shown in fig. 3, 6 and 10, the damping mechanism 50 includes a guide chamber and a force application cylinder. The guide cavities comprise two pairs of first guide cavities 51 arranged on the holding seat 10, and the two pairs of first guide cavities 51 are respectively positioned on two sides of the pivot center O, are symmetrically arranged and are opposite to the upper end of the ring body 20; the force application cylinders comprise two pairs of first force application cylinders 53 which are respectively and correspondingly arranged in the two pairs of first guide cavities 51; the two pairs of first force application cylinders 53 apply force to the upper end of the ring body 20 by the pressure gas entering the first guide chamber 51.

The advantages of the above embodiment are:

1. the pressure of the pressurized gas is easily adjusted, so that the force applied to the ring body 20 by the first force application column can be easily adjusted, and the rigidity between the columnar member 100 and the holder 10 can be adjusted (whereas the rigidity between the columnar member 100 and the holder 10 cannot be adjusted by using a spring as a force application member).

2. The sleeve body 40 can slightly float relative to the ring body 20 to absorb the vibration or impact transmitted from the processing tool 200 to the ring body 20 through the sleeve body 40.

3. The fixed connection between the sleeve 40 and the cylindrical member 100 can be realized by the cooperation of the arc-shaped notch and the arc-shaped locking lath 42 (meanwhile, the inner hole of the sleeve 40 and the cylindrical member 100 form clearance fit), and the cylindrical member 100 can be separated from the sleeve 40 by loosening the fastening piece, so that the assembly performance of the device is improved.

In some embodiments, the guide cavities further comprise two second guide cavities 52 opening in the holder 10 and located between each pair of first guide cavities 51, respectively; the force application cylinders further comprise two second force application cylinders 54 respectively arranged in the two second guide cavities 52, and the two second force application cylinders 54 are used for applying force to the upper end of the ring body 20; wherein: a tapered surface 541 is formed at the middle of the second force application cylinder 54; the surface working apparatus further includes two distance probes 80, and the two distance probes 80 radially extend into the two second guide cavities 52 from the outside of the holder 10, respectively, to obtain axial displacement of the second force application column by detecting a change in distance between the distance probes 80 and the circumferential surface of the second force application column 54.

It should be noted that: it is easy to understand that when the second force application cylinder 54 is at different axial positions, the distance detector 80 obtains different detection results, and the specific axial position of the second force application cylinder 54 can be calculated based on these detection results, and since the lower end of the second force application cylinder 54 is always in contact with the ring body 20, the postures of the ring body 20, the columnar member 100, and the processing tool 200, that is, the inclination angle in the direction perpendicular to the movement direction of the processing tool 200 can be obtained.

It should be noted that: since the columnar member 100 and the holder 10 are in the pivot state, in an initial state before the processing tool 200 processes the end surface 301 of the workpiece, the inclination of the columnar member 100 may cause the processing tool 200 to have a large inclination angle with respect to the end surface 301 of the workpiece, although this inclination state can be eliminated when the processing tool 200 is brought into contact with the end surface 301 of the workpiece with a certain contact force, so that the processing tool 200 coincides with the end surface 301, however, the columnar member 100 has a tendency to return to the inclination state throughout the entire processing due to the rigidity of the columnar member 100 with respect to the holder 10, which causes the contact force between the processing tool 200 and the end surface 301 of the workpiece to be uneven in the direction perpendicular to the linear movement, and the contact force between the processing tool 200 and the end surface 301 of the workpiece to be uneven when the processing is performed as the inclination angle of the processing tool 200 is larger before the processing of the workpiece, this will affect the quality of the process.

The above-described detection of the axial position of the second force application cylinder 54 by the distance detector 80 is used to adjust the tilt angle of the processing tool 200 before processing the workpiece to a smaller tilt angle as possible. According to the above, when the distance detector 80 detects that the inclination angle of the cylindrical component 100 is too large through calculation, the axial position of the corresponding second force application cylinder 54 can be adjusted by increasing or decreasing the pressure of one of the second guide cavities 52, so as to reduce the inclination angle of the cylindrical component 100, and further prevent the machining tool 200 from forming a large inclination angle with the end surface 301 of the workpiece before machining the workpiece, which is beneficial to reducing the non-uniformity of the contact force during machining, and further beneficial to improving the machining quality.

As described above, the second guide chamber 52, the second force application cylinder 54, and the distance detector 80 are added to reduce the inclination angle between the processing tool 200 and the processing plane as much as possible before the processing tool 200 processes the end surface 301 of the workpiece.

In some embodiments, two collars 72 are disposed on the mounting hole of the holder 10, the surface processing device further includes a sealing ring 70, a ring of bristles 71 is disposed on an inner wall of the sealing ring 70, and the sealing ring 70 is interposed between the two shaft collars 41, so that the bristles 71 block a gap between the mounting hole and the cylindrical member 100. The sealing ring 70 serves to prevent the passage of dust.

In some embodiments, the damping mechanism 50 further includes a cover 57, the cover 57 is fastened to the holder 10 for closing off the first guide cavity 51 and the second guide cavity 52; wherein: the cover 57 is provided with first air inlet ports 581 corresponding to the first guide chambers 51 one by one and second air inlet ports 582 corresponding to the second guide chambers 52 one by one. In this manner, each first guide chamber 51 may be supplied with pressurized gas via a corresponding gas line connected to each first gas inlet port 581, and each second guide chamber 52 may be supplied with pressurized gas via a corresponding gas line connected to each second gas inlet port 582. Preferably, a sealing ring 56 is provided between the outer side of each of the first guide chamber 51 and the second guide chamber 52 and the cover 57.

In some embodiments, a first sealing sleeve 61 is disposed between the upper end of the holder 10 and the cylindrical member 100, and a second sealing sleeve 62 is disposed between the lower end of the sleeve body 40 and the cylindrical member 100, and both sealing sleeves are used for limiting external dust from entering the mounting hole. .

In some embodiments, a bushing 55 is disposed between the first guide cavity 51 and the first force application cylinder 53 and between the second guide cavity 52 and the second force application cylinder 54, such that the bushing 55 has a lower wear resistance than the force application cylinder, so as to solve the problem of air leakage between the bushing 55 and the force application cylinder due to wear by replacing the bushing 55.
