Description

Technical Field

[0001] The invention relates to the technical field of copper tube grinding, in particular to a copper tube cutting and grinding device for automatic production of solar water heaters. Background Art

[0002] A solar water heater is a device that uses sunlight to heat water. It absorbs solar energy through a collector, converts light energy into heat energy, and then heats the water in the water tank. This water heater is environmentally friendly and energy-saving because it does not consume electricity or gas, reduces dependence on fossil fuels, and reduces household energy expenses. Solar water heaters require the use of heat exchange copper tubes. The manufacturing process of some copper pipes with complex shapes is: first cut the copper tube into short sections of a predetermined length, then use a bending process to form it, and finally weld and assemble it.

[0003] The raw material of the copper tube is a continuously wound copper tube, which needs to be corrected (straightened) first in the solar water heater manufacturing plant, and then transported through the cutting equipment to cut the copper tube into short sections of copper tubes of predetermined length, and then directly sent to the subsequent process. However, due to burrs on both ends of the short section copper tube during the cutting process, quality problems are prone to occur in the subsequent welding process. For this reason, the present invention provides a copper tube cutting and polishing device for the automated production of solar water heaters. Summary of the invention

DETAILED DESCRIPTION

[0068] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] Embodiment 1:

[0070] like Figure 1 - Fig.14As shown, an embodiment of the present invention provides a copper tube cutting and grinding device for automated production of solar water heaters, comprising: a guiding mechanism 3, a grinding mechanism 2 and an operating mechanism 1, which is designed at the end of the copper tube cutting of the copper tube system for automated production of solar water heaters, and is used for automated grinding and deburring of the short section of the copper tube after cutting, thereby facilitating subsequent processing of the short section of the copper tube, ensuring subsequent welding quality, and improving the quality of the solar water heater product.

[0071] Specifically, a guiding mechanism 3 is designed and arranged at the end of the copper tube cutting. The guiding mechanism 3 guides the short section copper tube to move in a direction perpendicular to the axial direction of the short section copper tube. The short section copper tube can be guided to roll on the guiding mechanism 3 without power by utilizing the circular characteristic of the short section copper tube. In addition, the axial direction of the short section copper tube is not changed in this process. It is more convenient to add it to the copper tube system for the automated production of solar water heaters. The grinding mechanism 2 is fixedly installed above the guiding mechanism 3, and the grinding mechanism 2 has at least one set of grinding components 203. The rotation centerline of the grinding component 203 is parallel to the central axis of the short section copper tube. The short-section copper tube can be manipulated in parallel so that the short-section copper tube is polished on the polishing assembly 203. One or two polishing mechanisms 2 can be designed to polish one end or both ends of the short-section copper tube. Since the diameters of the short-section copper tube may be different (different production batches), the polishing surface of the polishing assembly 203 is a conical surface, so that short-section copper tubes of various different diameters can be polished. The manipulation mechanism 1 is used to grab the short-section copper tube and complete the polishing of the end of the short-section copper tube on the polishing mechanism 2, and then put the short-section copper tube back to the guiding mechanism 3. The guiding mechanism 3 continues to guide the polished short-section copper tube to the next processing link.

[0072] The present invention mainly designs a grinding component with a conical grinding surface, which can grind the end of the short-section copper tube without changing the axial direction of the short-section copper tube (the movement of the short-section copper tube is all translation), and cooperates with the design of a guiding mechanism and an operating mechanism. The guiding mechanism 3 is arranged at the end of the copper tube cutting, and the guiding mechanism 3 guides the movement of the short-section copper tube in a direction perpendicular to the axial direction of the short-section copper tube, so that the entire copper tube cutting and grinding device for the automated production of solar water heaters can be quickly added to the end of the copper tube cutting of the existing copper tube system for the automated production of solar water heaters, completes the grinding of the end of the short-section copper tube, and improves the quality of the product.

[0073] In one embodiment, the grinding mechanism 2 is specifically designed to include: a horizontal plate frame 202 , a supporting frame 201 , a positioning back plate assembly 204 and a grinding assembly 203 .

[0074] Both ends of the bottom of the horizontal frame 202 are fixedly installed with support frames 201 to facilitate the overhead installation and fixing of the horizontal frame 202. The positioning backboard assembly 204 is fixedly installed on the side of the horizontal frame 202 away from the operating mechanism 1. The positioning backboard assembly 204 is used to position the short-section copper tube. Specifically, the operating mechanism 1 operates the short-section copper tube to be close to the positioning backboard assembly 204, so as to ensure that the end of the short-section copper tube corresponds to the grinding assembly 203 (the short-section copper tube coincides with the central axis of the grinding assembly 203). The grinding assembly 203 is provided with two groups The two groups of grinding assemblies 203 are symmetrically fixedly installed at the bottom of the horizontal plate frame 202, and the distance between the two groups of grinding assemblies 203 is greater than the length of the short-section copper tube. When in use, the operating mechanism 1 can operate the short-section copper tube to be placed between the two groups of grinding assemblies 203, and the operating mechanism 1 operates the short-section copper tube to move toward the first side to complete the grinding of the first end of the short-section copper tube. Then, the operating mechanism 1 operates the short-section copper tube to move toward the second side to complete the grinding of the second end of the short-section copper tube, thereby efficiently completing the grinding process of both ends of the short-section copper tube.

[0075] In one embodiment, the positioning back plate assembly 204 is specifically designed, and includes: a vertical plate frame 204a, an arc-shaped positioning frame 204c, a sliding arc-shaped member 204e, a sliding rod 204d, and a plurality of springs 204f.

[0076] The top of the vertical plate frame 204a is fixedly connected with a horizontally arranged mounting plate 204a1, and the mounting plate 204a1 is fixedly installed with the horizontal plate frame 202, and can be fixedly installed with four sets of bolts. The arc positioning frame 204c is fixedly installed on the side of the vertical plate frame 204a close to the operating mechanism 1 through multiple sets of supporting cross bars 204b, and multiple sets of supporting cross bars 204b are fixedly connected with the arc positioning frame 204c, and the arc positioning frame 204c is bolted to the vertical plate frame 204a. The design of the above structure is convenient for replacing arc positioning frames 204c of different sizes to adapt to the grinding of short sections of copper pipes of different diameters. A rectangular mounting area is opened in the middle section of the arc positioning frame 204c, and a bolt connected to the arc positioning frame is fixedly arranged in the inner side of the rectangular mounting area. The sliding rod 204d is consistent with the length direction of the positioning frame 204c, and a sliding arc member 204e is slidably installed on the sliding rod 204d. The inner side of the sliding arc member 204e protrudes compared to the inner side of the arc positioning frame 204c, and the center of the sliding arc member 204e coincides with the central axis of the grinding assembly 203. When in use, the short section of the copper tube will be in close contact with the inner side of the sliding arc member 204e, and the arc positioning frame 204c only plays a safety protection role (in normal use, the short section of the copper tube does not contact the inner side of the arc positioning frame 204c). Springs 204f are arranged on the sliding rod 204d and on both sides of the sliding arc member 204e. The springs 204f enable the sliding arc member 204e to have the function of automatic centering.

[0077] When in use, the operating mechanism 1 operates the short copper tube to press against the inner side of the sliding arc member 204e, and relies on the sliding arc member 204e to position the short copper tube, ensuring that when the operating mechanism 1 moves left and right (along the axial direction of the short copper tube), the sliding arc member 204e also moves left and right relative to the arc positioning frame 204c, avoiding friction between the short copper tube and the sliding arc member 204e, and the spring 204f enables the sliding arc member 204e to have the function of automatic centering.

[0078] In one embodiment, the present invention further specifically designs a grinding assembly 203, which specifically includes: an L-shaped frame 203a, a double-plate drag 203b, a driving member 203d and a grinding member 203e.

The double-plate drag 203b is fixedly installed on the vertical part of the L-shaped frame 203a through the fastening structure 203c, and the driving member 203d is clamped and fixed by the double-plate drag 203b and the vertical part of the L-shaped frame 203a. The axial direction of the driving member 203d is designed to be horizontal, and the output end of the driving member 203d is fixedly installed with a polishing member 203e.

[0080] The L-shaped frame 203a, the double-plate drag 203b and the fastening structure 203c can be conveniently installed with the driving member 203d, and the driving member 203d is used to drive the polishing member 203e to rotate and polish the end of the short copper tube.

[0081] Specifically, the double-board trailer 203b includes: a first plate 203b1 and a second plate 203b2 arranged in parallel, a short column 203b3 is fixedly connected between the first plate 203b1 and the second plate 203b2, so that the first plate 203b1, the second plate 203b2 and the short column 203b3 are fixed to form an integral structure, and the vertical portion of the L-shaped frame 203a is located between the first plate 203b1 and the second plate 203b2. The fastening structure 203c includes: a first oblique opening 203c1 opened on the side of the double-board drag 203b, an inclined surface 203c2 opened at the bottom of the vertical portion of the L-shaped frame 203a, a pressing plate 203c4 and screws 203c3. The screws 203c3 connect the pressing plate 203c4 with the inclined surface 203c2 at the bottom of the vertical portion of the L-shaped frame 203a, so that the pressing plate 203c4 acts on the first oblique opening 203c1 to lift the double-board drag 203b. Fig. 9 As shown in FIG. 2 , by tightening the screw 203c3, the pressing plate 203c4 can be moved upward, that is, the double-plate drag 203b moves upward and fixes the driving member 203d with the L-shaped frame 203a.

[0082] In one embodiment, the driving member 203d includes: a stator housing 203d1, a double-plate end cover 203d2, a rotor member 203d4 and a mounting plate 203d5.

[0083] A double-plate end cover 203d2 is fixedly installed on one end of the stator housing 203d1. The double-plate end cover 203d2 has two parallel annular plates, and the two annular plates are fixed together, so that the double-plate end cover 203d2 presents a thicker structure as a whole. An annular cavity 203d3 is formed on the inner side of the double-plate end cover 203d2. The rotor member 203d4, the stator housing 203d1, and the double-plate end cover 203d2 are rotatably installed through bearings, and one end of the rotor member 203d4 is located on the inner side of the annular cavity 203d3 and is fixedly connected to a mounting disk 203d5, and a threaded hole is formed at one end of the mounting disk 203d5 away from the rotor member 203d4.

[0084] In one embodiment, the grinding member 203e includes: a threaded connection head 203e1, a core column 203e3, conical leaves 203e4, an adjustment head 203e5 and an annular grinding belt 203e6.

[0085] The threaded connector 203e1 is threadedly connected to the threaded hole of the mounting disk 203d5, and a locking nut 203e2 is threadedly installed on the threaded connector 203e1. When installing the grinding piece 203e, the threaded connector 203e1 is threadedly connected to the threaded hole on the mounting disk 203d5, and then the locking nut 203e2 is reversed so that the locking nut 203e2 is against the end of the mounting disk 203d5. One end of the core column 203e3 is fixedly connected to the threaded connector 203e1, and the outer side of the core column 203e3 is fixedly connected to the disk body 203e7. Generally, the core column 203e3, the threaded connector 203e1 and the disk body 203e7 can be designed as an integrated structure. A plurality of conical leaves 203e4 are provided, and the plurality of conical leaves 20 3e4 are distributed in an annular array, and a gap is set between two adjacent conical leaves 203e4 to ensure that multiple conical leaves 203e4 can shrink inwardly, one end of the disk body 203e7 facing the core column 203e3 is fixedly connected with a connecting ear 203e8, the connecting ear 203e8 is rotatably installed with the conical leaf 203e4, one end of the adjusting head 203e5 is threadedly installed with the end of the core column 203e3, and a conical portion 203e5a is set on the side of the adjusting head 203e5, a conical mouth is set at the inner side of the conical leaf 203e4 corresponding to the conical portion 203e5a, a conical surface recess 203e4a is set on the outer side of the conical leaf 203e4, and an annular grinding belt 203e6 is sleeved on the conical surface recess 203e4a position of the conical leaf 203e4.

[0086] When installing the annular grinding belt 203e6, the user loosens the adjustment head 203e5.
