Problems solved by technology

During the working process, the gap between the adjustment screw 61 and the roller 121 changes, and the swinging process of the grinding block 25' will produce impact, resulting in vibration and a lot of noise
In order to maintain normal work, the above gap is strictly controlled within a certain range, otherwise vibration will occur, but in actual use, the control of this gap is relatively difficult, which may cause vibration of the grinding head and affect the normal operation of the grinding head , Only by adjusting the gap to the minimum can the above problems be overcome, but running in this way will accelerate the wear of the adjusting screw 61, and the gap needs to be adjusted frequently during the service life, which brings inconvenience to production
[0004] Simultaneously, when the active double-arm swing link 12 was in the horizontal position, the two rollers 121 above it were in contact with the end faces of the cam 13, but when this position was bypassed, the active double-arm swing link 12 had only a single roller 121 and the end face of the cam 13. The end surface of the cam 13 is in contact, and the other roller 121 is suspended away from the end surface of the cam 13. During the swinging process of the grinding head, the suspended roller 121 will contact the end surface of the cam 13 again, resulting in impact, resulting in vibration and noise
Moreover, the machining accuracy of the cam waveform curve end surface of the existing grinding head is high, and it is difficult to ensure that the waveform surfaces of the cam 13 are completely consistent. The machining error brings hidden dangers to the operation of the grinding head, and the interchangeability and versatility are very poor. ,high cost
[0005] (2) Swash plate grinding head: It also adopts the structure of the swinging grinding block mounting seat similar to the above. The kinematic pair of the swash plate grinding head is a low pair, which is wear-resistant and has a long service life, but it has a complex structure and high cost , the disadvantage of inconvenient maintenance
This patent effectively solves the vibration and noise problems caused by the existing cam-driven grinding block swing method, but the structure of the grinding head of this patent is complicated, and the inclined shaft installed on the inclined shaft mounting seat in the grinding head will have a certain degree of vibration after running for a period of time. The wear of the oblique axis and the installation gap between the oblique axis mounting seat needs to be adjusted, and it will affect the swing accuracy of the grinding head and thus affect the polishing accuracy

Embodiment 1

[0035] Such as image 3 with 4 As shown, an eccentric translational polishing grinding head includes an eccentric wheel 8, a dial 9 and a pendulum mechanism 10, the eccentric wheel 8 is connected to the dial 9, and the geometric center O of the eccentric wheel 8 2 Coincident with the geometric center of the dial 9, the rotation center O of the eccentric wheel 8 1 Located at the geometric center O of the eccentric wheel 8 2 One side, the rotation center O of the eccentric wheel 8 1 and the geometric center O 2 An eccentricity is formed between them, several radial grooves 91 are arranged on the dial 9 along the circumferential direction of the dial 9, and a single radial groove 91 is arranged along the radial direction of the dial 9, the One end of the swing rod mechanism 10 is provided with a swing rod ball head, which is inserted into the radial groove 91, and the swing rod ball head slides in the radial direction of the radial groove 91, and the swing rod ball The diame...

Embodiment 2

[0044] This embodiment only describes the difference from the above embodiment, and other technical features are the same as the above embodiment. Both ends of the radial groove 91 are closed ends, which prevent the ball head of the swing rod from slipping out along the radial direction of the radial groove 91 .

Abstract

The invention discloses an eccentric translation type polishing grinding head. The eccentric translation type polishing grinding head comprises an eccentric wheel, a drive plate and oscillating bar mechanisms, wherein the eccentric wheel is connected with the drive plate, the geometric center of the eccentric wheel coincides with the geometric center of the drive plate, the gyration center of eccentric wheel is located at one side of the geometric center of the eccentric wheel, eccentric distance exists between the gyration center of the eccentric wheel and the geometric center of the eccentric wheel, a plurality of radial slots are arranged around the circumference of the drive plate, oscillating bar ball heads of the oscillating bar mechanisms are inserted into the radial slots, when theeccentric wheel rotates, the drive plate does not rotate but horizontally and circularly moves in a plane along an X axis and a Y axis, when the drive plate moves, each oscillating bar mechanism continuously circularly swings along the radial direction of the corresponding radial slot under the action of the side face of the corresponding radial slot and the corresponding oscillating bar ball head, and it is achieved that a grinding block connected to one end of each oscillating bar mechanism circularly swings. The eccentric translation type polishing grinding head and the polisher containingthe grinding head have the advantages that the structure is simple, it is achieved that when the grinding blocks revolve around the grinding heads, the grinding blocks can circularly swing at the same time, the grinding efficiency on ceramic tile is high, the operation is smooth and steady, and the reliability is high.

Description

technical field [0001] The invention relates to the field of porcelain tile polishing equipment, in particular to an eccentric translation polishing grinding head and a polishing machine including the grinding head. Background technique [0002] In the existing polishing device of the porcelain tile polishing production line, the polishing grinding head is an important part in the polishing production line, such as figure 1 As shown, the working process is as follows: the grinding head drives the grinding block mounting seat 24` to revolve and at the same time makes the grinding block mounting seat 24` reciprocate and swing continuously, and the grinding movement of the grinding head is the circular rotation of the grinding block 25` around the main shaft Motion and the compound movement of the left and right rotation and swing of the grinding block 25 ′ around the rotating shaft 7, the grinding block 25 ′ is in linear contact with the ground plane, so the grinding pressure ...
