Description

Technical Field

[0002] At present, in the production process of toilets, it is necessary to grind the surface of the toilet blank and remove the surface dust in order to carry out the subsequent surface porcelain coating process. However, in the existing production process, the grinding operation is generally done manually, and the dust removal operation is also done manually by wiping and flushing. Since the toilet blank is usually heavy and its position is not easy to adjust, the grinding operator needs to adapt to the operation of the operation by bending, bending or twisting the body and walking around the toilet blank. Generally, the continuity of the work of employees is low. Bending, bending or twisting for a long time will easily cause fatigue to the operator's body, thereby reducing the efficiency and effect of the operation and failing to ensure the overall quality of the product. For production lines that use robot arms for operation, it is often necessary to manually realize the clamping and positioning of the toilet blank, and then further complete the grinding and trimming of the toilet blank. This clamping and positioning method is often inefficient and not suitable for assembly line automatic operation on the production line. Utility Model Content

The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0034] See also Figures 1 to 11 A position adjustment device for surface finishing of toilet blanks comprises a base 1, a support platform 2 fixedly arranged above the base 1, conveying support mechanisms 3 are symmetrically arranged on both sides of the top surface of the support platform 2, a lateral positioning block 4 is fixedly arranged on the top of the conveying support mechanism 3 on one side, and a plurality of lateral positioning mechanisms 5 fixed on the top surface of the support platform 2 and arranged opposite to the lateral positioning block 4 are distributed in the conveying support mechanism 3 on the other side, a forward positioning mechanism 6 located between the two conveying support mechanisms 3 is arranged at the discharge end of the top surface of the support platform 2, a lifting and rotating positioning mechanism 7 is arranged at the center of the support platform 2, a power output end of the lifting and rotating positioning mechanism 7 is fixedly connected to a supporting plate 8 located above the support platform 2, and a toilet blank placing plate 9 is movably placed on the top surface of the supporting plate 8.

[0035] Specifically, the four corners of the bottom surface of the support platform 2 are fixedly connected to the top surface of the base 1 through the fixed columns 10, so that the support platform 2 is fixedly set, and the top surface of the support platform 2 is located near the waist height of the human body through the base 1 and the fixed columns 10, so that the operator can perform all-round grinding and finishing operations and dust cleaning operations on the outer surface of the toilet base 100 above the top surface of the support platform 2. When the industrial robot arm is used to grind and finish the surface of the toilet base 100 and clean the dust, the vertical height position of the support platform 2 is preferably to meet the operating range of the shortest stroke of the industrial robot arm.

[0036] like Figure 5As shown, the conveying support mechanism 3 includes a driving motor 301 fixedly mounted on one side of the bottom surface of the support platform 2, and a plurality of groups of supporting columns 302 fixedly arranged linearly on one side of the top surface of the support platform 2. A supporting roller 303 is rotatably connected in each group of supporting columns 302, and a driven synchronous pulley 304 is fixedly connected to the outer shaft end of the supporting roller 303. The output shaft end of the driving motor 301 is fixedly connected to a driving synchronous pulley 305, and the driving synchronous pulley 305 and each driven synchronous pulley 304 are connected through a synchronous belt 306. The driving motor 301 is a stepper motor or a servo motor, and a reducer is configured at its output shaft end, and the driving synchronous pulley 305 is fixedly mounted on the power output end of the reducer. The driving motor 301 and / or the reducer are fixedly mounted on the bottom surface of the support platform 2 through a mounting seat. There are two support columns 302 in each group. The centers of the two side end surfaces of the support roller 303 are respectively provided with rotating shafts. The shaft ends or shaft diameters of the rotating shafts are rotatably installed in the support columns 302 through rolling bearings, so that the highest point of the cylindrical surface of the support roller 303 is located above the top surfaces of the two support columns 302. The driven synchronous pulley 304 is fixedly connected to the shaft end of the outer rotating shaft of the support roller 303. The top surface of the support platform 2 is respectively provided with synchronous belt grooves 201 (such as Figure 8 As shown in the figure, the driven synchronous pulley 304 is located just above the synchronous belt groove 201, the driving synchronous pulley 305 is located just below the synchronous belt groove 201, and the synchronous belt 306 is located in the synchronous belt groove 201. In this way, through the drive of the drive motor 301 and the transmission of the synchronous belt transmission device, each support roller 303 can be driven to rotate synchronously, so that the toilet blank placement plate 9 placed on the support roller 303 can be driven to move forward, so that the toilet blank placement plate 9 and the toilet blank 100 placed thereon can be transported forward.

[0037] Preferably, a synchronous belt tensioning plate 307 whose position can be adjusted up and down is connected to the side of the support column 302, and the bottom surface of the synchronous belt tensioning plate 307 is in sliding contact with the top surface of the synchronous belt 306. The synchronous belt tensioning plate 307 is an inverted "L"-shaped structure, and a waist-shaped through groove is provided in its vertical section, and a locking screw threadedly connected to the side of the support column 302 is provided in the waist-shaped through groove. When the locking screw is loosened, the position of the synchronous belt tensioning plate 307 can be adjusted up and down to adjust the tensioning pressure of the synchronous belt 306, and then the locking screw is tightened to fix the position of the synchronous belt tensioning plate 307. By adjusting the tensioning pressure of the synchronous belt 306, the reliability of the meshing transmission between the synchronous belt 306 and each driven synchronous pulley 304 can be ensured, and the synchronous belt 306 can be prevented from being loosened after a certain period of use and slipping with the driven synchronous pulley 304.

[0038] like Figure 6As shown, the lateral positioning mechanism 5 includes a lateral positioning cylinder 501 fixedly arranged on the top surface of the support platform 2 and located between two adjacent groups of support columns 302, a horizontal guide rail 502 fixedly arranged on the top surface of the support platform 2 and located inside the lateral positioning cylinder 501, a lateral push plate 503 located inside the synchronous belt 306 is fixedly connected to the output shaft end of the lateral positioning cylinder 501, and a first guide slider slidably embedded in the horizontal guide rail 502 is fixedly connected to the bottom surface of the lateral push plate 503. The top of the lateral push plate 503 is located above the highest point of the cylindrical surface of the support roller 303. In the process of the conveying support mechanism 3 driving the toilet blank placing plate 9 to move forward, the output shaft of the lateral positioning cylinder 501 extends, pushing the lateral push plate 503 to approach and contact the toilet blank placing plate 9, and then pushing the toilet blank placing plate 9 to move to the other side until the other side of the toilet blank placing plate 9 fits with the side of the lateral positioning block 4. After a single positioning is completed, the output shaft end of the lateral positioning cylinder 501 shrinks, so that the lateral push plate 503 moves away from the toilet blank placement plate 9 and resets. When the toilet blank placement plate 9 continues to move, the output shaft end of the lateral positioning cylinder 501 periodically extends and shrinks again, and the position of the toilet blank placement plate 9 on the support roller 303 is continuously adjusted. When at least two lateral push plates 503 simultaneously perform lateral positioning on the toilet blank placement plate 9, the other side of the toilet blank placement plate 9 is blocked by the corresponding lateral positioning block 4, so that the lateral positioning of the toilet blank placement plate 9 in the moving direction can be achieved.

[0039] like Figure 7 As shown, the forward positioning mechanism 6 includes a forward positioning cylinder 601 fixedly arranged on the bottom surface of the discharge end of the support platform 2, a vertical guide slide rail 602 fixedly arranged on the top surface of the support platform 2 and located above the forward positioning cylinder 601, the output shaft end of the forward positioning cylinder 601 movably penetrates the support platform 2 and is fixedly connected with a forward positioning baffle 603, and the side of the forward positioning baffle 603 is fixedly connected with a second guide slider slidably embedded in the vertical guide slide rail 602. When the output shaft of the forward positioning cylinder 601 is extended, the forward positioning baffle 603 moves vertically upward, and its top is located above the highest point of the cylindrical surface of the support roller 303. In this way, when the conveying support mechanism 3 drives the toilet blank placement plate 9 to move forward, the front end of the toilet blank placement plate 9 is positioned under the obstruction of the forward positioning baffle 603, and the cylindrical surface of the support roller 303 and the bottom surface of the toilet blank placement plate 9 rotate relative to each other, and the support roller 303 is in an idling state.

[0040] Through the cooperation between the forward positioning mechanism 6 and the lateral positioning mechanism 5, the accurate positioning of the toilet blank placement plate 9 on the conveying support mechanism 3 can be achieved. After the positioning is completed, the conveying support mechanism 3 stops working, and the forward positioning mechanism 6 and the lateral positioning mechanism 5 are also reset and stopped working, which can ensure that the toilet blank placement plate 9 and the toilet blank 100 thereon are in the preset working position. Since the toilet blank 100 itself has a large mass and the support roller 303 is also in a locked state, the force applied to the toilet blank 100 by the manual or industrial robot arm during the grinding and finishing operation and dust cleaning operation on the surface of the toilet blank 100 is not enough to cause the toilet placement plate 9 and the support roller 303 to have a relative displacement in the plane direction.

[0041] Preferably, the width of the toilet blank placement plate 9 is not less than the minimum spacing between the support rollers 303 on both sides, so that the two sides of the toilet blank placement plate 9 can be reliably overlapped on the support rollers 303 on both sides to prevent one side from falling off the support rollers 303 completely during the advancement or position adjustment process. Furthermore, a toilet blank pre-set groove 901 is provided on the top surface of the toilet blank placement plate 9, which can facilitate the efficient placement of the toilet blank 100 on the toilet blank placement plate 9 and facilitate the accurate pre-positioning of the toilet blank 100 on the toilet blank placement plate 9 (such as Fig.12 As shown), in the subsequent process, it is only necessary to complete the positioning of the toilet base placement plate 9 to correspondingly achieve the positioning of the toilet base 100.

[0042] like Figures 9 to 11 As shown, the lifting and rotating positioning mechanism 7 includes a lifting cylinder 701 fixedly arranged on the top surface of the base 1, a guide column 702 fixedly arranged on the side of the lifting cylinder 701, a lifting plate 703 fixedly connected to the output shaft end of the lifting cylinder 701 and slidably sleeved on the outside of the guide column 702, a sleeve 704 fixedly arranged on the top surface of the lifting plate 703 and movably passing through the support platform 2, and a rotating column 705 rotatably connected to the sleeve 704. The supporting plate 8 is fixedly connected to the top end surface of the rotating column 705, and a driven gear 706 coaxially arranged on the outside of the rotating column 705 is fixedly connected to the bottom surface of the supporting plate 8. A rotating positioning motor 707 is fixedly connected to the outer wall of the sleeve 704, and a driving gear 708 meshing with the driven gear 706 is fixedly connected to the output shaft end of the rotating positioning motor 707.

[0043] The lifting cylinder 701 and the guide column 702 are respectively fixedly connected to the top surface of the support platform 2 by bolts. There are four guide columns 702, which are evenly distributed around the outer side of the lifting cylinder 701. The output shaft end of the lifting cylinder 701 is threadedly connected with a connector 7014 with a T-shaped cross section, and the bottom surface of the lifting plate 703 is fixedly connected with a connector seat 7013 matching the connector 7014. The connector 7014 is inserted from the side of the connector seat 7013 to achieve the connection between the output shaft end of the lifting cylinder 701 and the lifting plate 703. The lifting cylinder 701 drives the lifting plate 703 to move up and down, thereby driving the sleeve 704, the rotating column 705 and the supporting plate 8 thereon to rise and fall synchronously, and the guide column 702 guides the lifting and falling of the lifting plate 703.

[0044] The vertical cross-section of the rotating column 705 is in a "T" shape, and its upper shaft diameter is rotatably mounted on the inner upper part of the sleeve 704 through the thrust bearing 7011 and the first rolling bearing 7012, and its lower shaft diameter is rotatably mounted on the inner lower part of the sleeve 704 through the second rolling bearing 709. An annular protrusion is provided on the upper inner wall of the sleeve 704, and the upper end surface of the annular protrusion is used for the bottom axial positioning of the thrust bearing 7011, and the lower end surface of the annular protrusion is used for the top circumferential positioning of the first rolling bearing 7012. The lower end surface of the first rolling bearing 7012 and the upper and lower end surfaces of the second rolling bearing 709 are respectively axially positioned through retaining rings embedded on the inner wall of the sleeve 704. Through the bearing combination, the rotating column 705 can be rotatably mounted in the sleeve 704, and the rotating column 705 has a preset vertical support capacity.

[0045] The outer side of the sleeve 704 is integrally provided with or welded with a motor mounting plate, and the rotation positioning motor 707 is fixedly installed on the bottom surface of the motor mounting plate so that its output shaft end is vertically arranged upward, and the rotation positioning motor 707 adopts a stepping motor or a servo motor. In order to make the structural design more compact, in this embodiment, an internally meshing gear pair is adopted, that is, the driven gear 706 adopts a gear ring structure, and the driving gear 708 is arranged on the inner side of the driven gear 706 to realize the reduction transmission.

[0046] Preferably, a lip seal ring 7010 is provided between the top outer side of the rotating column 705 and the top inner side of the sleeve 704 to prevent dust particles generated during the grinding and dust cleaning operations of the toilet blank 100 from entering the sleeve 704 and causing damage to the bearing, thereby ensuring the smooth rotation of the rotating column 705 in the sleeve 704.

[0047] After the toilet blank placement plate 9 is positioned on the conveying support mechanism 3, if the position of the toilet blank 100 needs to be adjusted to facilitate the operation, the output shaft end of the lifting cylinder 701 is extended to drive the supporting plate 8 to rise, thereby lifting the toilet blank placement plate 9 to the top of the conveying support mechanism 3, and then the rotary positioning motor 707 works, driving the supporting plate 8 to rotate around the vertical axis by a preset angle through a gear pair (this angle must ensure that the outermost edge of the rotating supporting plate 8 is located on the inner side of the innermost side of the support column 302), then the toilet blank placement plate 9 and the toilet blank 100 thereon also rotate synchronously by the same angle; then the output shaft end of the lifting cylinder 701 is shortened, so that the supporting plate 8 drops to its top surface below the top end of the cylindrical surface of the support roller 303, and the rotated toilet blank placement plate 9 is re-erected on the conveying support mechanism 3, and the rotary positioning motor 707 works in the reverse direction, driving the supporting plate 8 to rotate around the vertical axis in the reverse direction by a preset angle through a gear pair, so that the supporting plate 8 is reset. The above process is repeated to further adjust the horizontal angle of the toilet base 100 .

[0048] After completing all operations on the toilet blank 100, the conveying support mechanism 3 continues to work to convey the toilet blank placement plate 9 and the toilet blank 100 thereon to the next process position.

[0049] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
