Description

Technical Field

[0001] The utility model relates to the technical field of polishing settings, in particular to a swing type polishing machine head. Background Art

[0002] In order to improve the flatness of the outer surface of the workpiece, many workpieces such as floors, auto parts, plumbing, hardware, etc. need to be ground and polished through a polishing process. During the polishing process, the polished workpiece needs to contact the cross-section of the polishing wheel. Traditional polishing devices such as sanding belts or polishing wheels generally only provide the movement of abrasives on a certain section of the tool on the section, and process a point on the workpiece at the same time. Since the height of the highest abrasive on each section of the tool cannot be completely consistent and fluctuates, it will leave obvious marks on the workpiece processing surface, which is difficult to meet the high requirements of surface finish.

[0003] The Chinese patent application number CN201821492505.4 discloses a swing-type polishing machine, and its specification and drawings record that "the two ends of the bottom of the slider 33 are respectively provided with two downwardly protruding bearing seats 331; the two bearing seats 331 are respectively provided with a first bearing 34 and a second bearing 35. In this embodiment, the bearing close to the polishing wheel 11 is the second bearing 35, and the rotating shaft 12 passes through the second bearing 35 and the first bearing 34 in sequence, so as to be supported by the bearing seat 331. Figure 2 As shown, the second pulley 23 is located between the first bearing 34 and the second bearing 35. During the use and application process, the polishing wheel is adjacent to the second bearing. At the same time, the second pulley is located between the first bearing and the second bearing. All the weight is concentrated on the end of the rotating shaft. As a result, the pressure on the second bearing adjacent to the polishing wheel is greater than the pressure on the first bearing. As a result, the second bearing is more easily damaged. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-2 As shown, the swing polishing machine head of the utility model includes a fixed seat 01 fixedly connected to an external frame, a driving cylinder 02 and a driving motor 03 are fixedly installed on the outer circumference of the fixed seat 01 by fasteners, and a connecting plate 04 is arranged on the end of the fixed seat 01. The output end of the driving cylinder 02 is fixedly connected with the connecting plate 04, and the connecting plate 04 is driven to reciprocate in the left and right directions on the fixed seat 01 by the output end of the driving cylinder 02. The connecting plate 04 is slidably connected to the fixed seat 01. The connecting seat 05 on the connecting plate 04, the driving cylinder 02 on the fixed seat 01 drives the connecting plate 04 to move in the left and right directions on the fixed seat 01.

[0020] A rotating hole 06 is horizontally arranged in the connecting seat 05, and a bearing 07 is fixedly installed in the rotating hole 06. A driving shaft 08 is fixedly installed on the bearing 07. Under the action of the bearing 07, the driving shaft 08 rotates in the connecting seat 05. Other bearings can also be installed in the rotating hole 06, as long as the driving shaft 08 can rotate on the connecting seat 05. The two ends of the driving shaft 08 extend outside the connecting seat 05 respectively. A pulley 09 and a polishing wheel 10 are fixedly installed on the driving shaft 08, so that the pulley 09 and the polishing wheel 10 are located on both sides of the connecting seat 05. Both ends of the driving shaft 08 can be stressed. Since both ends of the driving shaft 08 can be stressed, the multiple bearings 07 in the connecting seat 05 are stressed evenly, extending the service life of the bearing 07. Thereby extending the service life of the polishing machine head. The pulley 09 is drivenly connected to the output end of the driving motor 03 through the V-belt 11. Taking full advantage of the characteristics of the pulley transmission, the polishing wheel 10 is driven by the driving motor 03 to process the surface of the workpiece.

[0021] The end of the driving shaft 08 is provided with a connecting shaft 12, and the above-mentioned polishing wheel 10 is installed on the connecting shaft 12. The end of the driving shaft 08 is provided with a threaded hole, and the thread direction of the threaded hole is opposite to the rotation direction of the polishing wheel 10. The driving shaft 08 is provided with a flat square 13, and the connecting shaft 12 is provided with a connecting hole 14 adapted to the flat square 13. The flat square 13 and the connecting hole 14 are matched to prevent the relative displacement and rotation between the connecting shaft 12 and the driving shaft 08. During installation, the connecting shaft 12 is first sleeved on the driving shaft 08 according to the direction of the flat square 13, and then the fastener is passed through the connecting shaft 12 and the threaded hole on the driving shaft 08 to achieve a fixed connection between the connecting shaft 12 and the driving shaft 08. In terms of processing cost, the cost required for processing the flat square 13 is lower than the cost of processing the keyway and key. From the installation point of view. The installation method using the flat square 13 is more convenient and quick.

[0022] A fixing plate 15 and a clamping plate 16 are provided on the connecting shaft 12, and the fixing plate 15 is fixedly connected to the connecting shaft 12 by welding. The clamping plate 16 is detachably connected to the fixing plate 15 by fasteners. A clamping groove is provided between the fixing plate 15 and the clamping plate 16, and the polishing wheel 10 is installed in the clamping groove and is fixed to the connecting shaft 12 by fasteners that pass through the clamping plate 16, the polishing wheel 10 and the fixing plate 15 in sequence.

[0023] The fixing seat 01 is provided with a mounting groove 17 which is arranged parallel to the driving shaft 08. A linear guide rail 18 is fixedly installed in the mounting groove 17. The connecting plate 04 is provided with a limit groove which is adapted to the linear guide rail 18. The linear guide rail 18 is a standard fixed part purchased from outside. The matching of the mounting groove 17 and the limit groove prevents the linear guide rail 18 from being displaced between the fixing seat 01 and the connecting plate 04 during operation.

[0024] The fixing seat 01 is provided with a receiving hole 19 for receiving the V-belt 11, and the output end of the driving motor 03 is fixedly provided with a driving wheel 20, which is located in the receiving hole 19. The driving wheel 20 and the pulley 09 are connected by a V-belt 11 transmission, and the receiving hole 19 is provided. The V-belt 11 is located in the receiving hole 19, so that objects outside the fixing seat 01 are prevented from contacting the V-belt 11, thereby improving the safety of the polishing machine head.

[0025] A protective cover 21 is also provided on the fixing seat 01. The protective cover 21 is fixedly connected to the fixing seat 01 by fasteners and is provided on the connecting seat 05. The setting of the protective cover 21 is to improve the safety of the optical head and to prevent dust from entering the rotating hole 06 of the connecting seat 05, thereby improving the service life of the bearing 07 in the rotating hole 06.

[0026] It should be noted that, for the sake of clarity of description, the fasteners described in this application are any one of screws, bolts, and screws.

[0027] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.
