Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, in particular to a conveying equipment used in a brake caliper housing heat treatment production line. Background Art

[0002] Brake caliper housings are typically made of either plastic or metal. Metal requires heat treatment during manufacturing. Heat treatment can significantly improve the metal's mechanical properties by altering its microstructure, while also eliminating internal stress and increasing wear resistance and fatigue strength.

[0003] The heat treatment production line requires the use of conveying equipment such as chain conveyors. Common chain conveyors, in addition to their conveying function, also have a tensioning structure, but their tensioning structure is manually adjusted. However, as the chain plates of the chain conveyor continue to pass through the heat treatment equipment, they will gradually heat up. When the temperature rises to a certain level, the entire chain will deform due to thermal expansion and contraction, resulting in changes in the chain length between the sprockets. At this time, the sprockets cannot change the spacing, so the chain will be over-tensioned. The chain in an over-tensioned state is prone to excessive friction with the sprockets, and may even break due to continuous operation in an over-tensioned state.

[0004] In addition, the chain requires regular maintenance and oiling. The benefits of chain oiling mainly include reducing friction, extending the chain life, protecting the chain from corrosion and keeping the chain running smoothly. However, the existing chain oiling is divided into manual and automatic. The manual method is to use props such as a brush to apply oil to the chain through friction, while the electric method is to continuously spray oil onto the chain through a nozzle. However, manual operation is more troublesome, and electric spraying is prone to waste. Summary of the Invention

The lifting mechanism is connected to a connecting rod 19, and the front and rear ends of the connecting rod 19 are fixedly connected to a connecting seat 22, and the lower end of the connecting seat 22 is fixedly connected to an oil filling cylinder 23. An oil supply mechanism for supplying oil to the two groups of oil filling cylinders 23 is provided on the side frame 2, and an oil nozzle 28 is provided at the lower end of the two groups of oil filling cylinders 23. A second screw 29 is movably inserted into the upper end of the connecting seat 22, and the lower end of the second screw 29 is fixedly connected to a piston rod 30, which is movably inserted in the upper end of the oil filling cylinder 23. A piston block 31 is movably provided inside the oil filling cylinder 23, and the upper end of the piston block 31 is fixedly connected to the lower end of the piston rod 30. An elastic component is provided on the second screw 29, and a shift rod 43 is rotatably installed on the right side of the lower end of the connecting seat 22, and a transmission component is provided between the shift rod 43 and the piston rod 30. The first motor 6 and the rotating shaft 5 are connected via a reducer. The non-contact temperature sensor 15 can adopt non-contact detection equipment such as infrared or visual. The connection method, detection means and working principle are all existing mature technologies, so they will not be elaborated here.

[0035] As a preferred implementation in this embodiment, Figure 2 and Figure 3 As shown, the tensioning mechanism includes a fixed plate frame 10, which is fixedly connected between the right inner walls of the two groups of side frames 2, and a second motor 11 is fixedly installed on the fixed plate frame 10. A first screw 12 is rotatably installed on the fixed plate frame 10, and the left end of the first screw 12 is connected through the output end of the second motor 11. A first screw sleeve 13 is provided on the first screw 12 through a threaded sleeve, and the first screw sleeve 13 is fixedly installed on the left end of the connecting frame 14. A non-contact temperature sensor 15 is fixedly installed on the upper end of the connecting frame 14, and a connecting sleeve 16 is fixedly connected to the right end of the connecting frame 14, and the connecting sleeve 16 is connected to the right rotating shaft 5 through a bearing sleeve.

[0036] The detection head of the non-contact temperature sensor 15 is vertically upward and located in the middle of the chain plate 9. The connecting sleeve 16 is connected to the middle of the rotating shaft 5 through the bearing sleeve. The fixed plate frame 10 and the first screw 12 are parallel to the slide 3. When the non-contact temperature sensor 15 detects the temperature of the chain plate 9, it can control the second motor 11 to adjust the tension according to the linear expansion coefficient of the metal thermal expansion coefficient. The linear expansion coefficient of the metal thermal expansion coefficient refers to the ratio of the change in unit length of the metal material to the original length when the temperature changes by 1°C. If the chain 8 and the chain plate 9 are made of aluminum alloy, the linear expansion coefficient of the metal thermal expansion coefficient is approximately 23.5×10 -6 / ℃ to 24×10 -6 / ℃, when the non-contact temperature sensor 15 detects that the temperature of the chain plate 9 reaches the preset value, the preset value should be that the chain plate 9 and the chain 8 produce thermal expansion and contraction of more than 1CM under the influence of excessive high temperature and subsequent cooling, resulting in excessive change in the length of the chain 8 between the left and right sets of sprockets 7, thereby affecting the normal operation and transmission between the sprockets 7 and the chain 8. Therefore, when the chain 8 and the chain plate 9 work continuously and bring the brake caliper housing into the heat treatment equipment and out, they themselves will heat up. When the temperature is higher than the preset value, the chain 8 and the chain plate 9 will expand and contract. And as the temperature continues to rise, the linear expansion coefficient of the metal's thermal expansion and contraction coefficient becomes higher. After the heat treatment device stops, the chain 8 and the chain plate 9 will cool down and will also shrink due to the temperature drop. Therefore, the second motor 11 drives the first screw 12 to rotate, so that the first screw sleeve 13 drives the right rotating shaft 5 to move laterally through the thread action, thereby compensating for the displacement caused by the thermal expansion and contraction of the material, so as to ensure that the chain 8 and the chain plate 9 can always be in a normally tensioned state, without being over-tensioned, ensuring normal operation, and reducing the adverse effects caused by thermal expansion and contraction during operation.

[0037] As a preferred implementation in this embodiment, Figure 5 and Figure 6 As shown, the lifting mechanism includes an electric push rod 18, which is fixedly mounted on the lower end of the hanger 17. The movable rod end of the electric push rod 18 is fixedly connected to the connecting rod 19. Guide holes 20 are symmetrically provided at both ends of the connecting rod 19. A guide rod 21 is movably inserted into the guide hole 20, and the lower end of the guide rod 21 is fixedly connected to the lower end of the hanger 17.

[0038] In this structure, the two sets of guide rods 21 and the electric push rod 18 are arranged in parallel. This structure is used to drive the two sets of connecting seats 22 to rise and fall vertically through the electric push rod 18, so that the lever 43 and the oil nozzle 28 are aligned with the chain 8 or away from it to trigger or close the oil injection.

[0039] As a preferred implementation in this embodiment, Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the rear lower sides of the two groups of oil filling cylinders 23 are both provided with connecting ports 24, an oil barrel 26 is fixedly installed on the rear side frame 2, and a liquid discharge pump 27 is provided on the lower side of the oil barrel 26. The lower end discharge port of the oil barrel 26 is connected to the feed port of the liquid discharge pump 27, and the two groups of connecting ports 24 are connected to the discharge port of the liquid discharge pump 27 through a connecting hose 25.

[0040] In this structure, the upper end of the oil barrel 26 is provided with a feed port, and a sealing cover is screwed on the feed port through a thread. The connecting hose 25 connected to the front oil filling cylinder 23 is horizontally arranged on the connecting rod 19 through a pipe rack. This method is used to ensure that the connecting hose 25 does not droop excessively and cause contact with the chain 8 or the chain plate 9. This structure increases the stability and rate of oil discharge through the liquid discharge pump 27.

[0041] As a preferred implementation in this embodiment, Figure 7 and Figure 9 As shown, the inner end opening of the connecting port 24 is located on the lower side of the inner wall of the oil filling cylinder 23. The inner end opening diameter of the oil filling cylinder 23 is smaller than the thickness of the piston block 31. The lower end of each group of oil filling cylinders 23 is provided with two groups of oil nozzles 28 in an eight-shaped shape.

[0042] In this structure, the outer openings of the two groups of oil nozzles 28 are respectively aligned with the inner ends of the chain 8, and this structure allows the lubricating oil to naturally flow to the bottom of the oil filling cylinder 23 when entering the oil filling cylinder 23 through the connecting port 24. When the piston block 31 is at the lowermost end of the oil filling cylinder 23, it will block the inner opening of the connecting port 24, thereby closing it and stopping the oil supply. At the same time, when the oil is sprayed outward through the oil nozzle 28, it will be aligned with the gaps in the rollers, sleeves, pins and other parts of the chain 8, thereby ensuring that the lubricating oil can well lubricate the chain 8.

[0043] As a preferred implementation in this embodiment, Figure 8 and Figure 9 As shown, the elastic component includes a second screw sleeve 33 connected to the second screw rod 29 through a threaded sleeve, a hexagonal knob 34 is fixedly provided at the lower end of the second screw sleeve 33, and a spring 32 is provided between the second screw sleeve 33 and the upper end of the connecting seat 22, and the upper and lower ends of the spring 32 are respectively against the upper end of the connecting seat 22 and the second screw sleeve 33.

[0044] In this structure, a guide groove is provided on the surface of the second screw 29, and a through hole is provided on the upper end of the connecting seat 22 for the vertical movement of the second screw 29, and a guide block is provided in the through hole to match the guide groove on the surface of the second screw 29. The guide block slides vertically in the guide groove, so that the second screw 29 cannot rotate on its own, but can be raised and lowered. At the same time, this structure enables the spring 32 to push the piston block 31 downward through the restorative force, thereby pushing out the lubricating oil. In addition, the preset elastic force can be adjusted by adjusting the height of the hexagonal knob 34, and the hexagonal knob 34 can be turned to adjust the preset elastic force. The second screw sleeve 33 rotates and performs threading action with the second screw rod 29 to achieve up and down movement. When the second screw sleeve 33 moves up, it squeezes the second screw sleeve 33, and the squeezing force increases as the second screw sleeve 33 rises. On the contrary, when the second screw sleeve 33 descends, the squeezing force on the second screw sleeve 33 decreases, and the squeezing force on the second screw sleeve 33 increases, and the strength of its restoring force will also increase. At the same time, the triggering rotation force of the shift rod 43 will also increase. When the restoring force increases, the spring 32 drives the piston block 31 to move downward faster through the rebound.

[0045] As a preferred implementation in this embodiment, Figure 8 、 Figure 9 and Figure 10 As shown, the transmission assembly includes a connecting hose 25, a connecting block 35 is fixedly sleeved on the lower side of the second screw 29, a tooth plate 36 is fixedly provided on the left end of the connecting block 35, a slider 37 is fixedly connected to the tooth plate 36, a slide 38 adapted to the slider 37 is fixedly provided on the connecting seat 22, balls 39 are equidistantly provided on the inner wall of the slide 38, the slider 37 is slidably set in the slide 38, two groups of transmission shafts 40 are rotatably installed on the left side of the connecting seat 22 through bearings, and a first gear 41 and a second gear 42 are fixedly installed on the two groups of transmission shafts 40 respectively, the second gear 42 is meshed with the right side of the tooth plate 36 and the tooth plate 36, the left side of the first gear 41 is meshed with the second gear 42, and a shift rod 43 is fixedly provided on the lower side of the second gear 42.

[0046] This structure allows the lever 43 to move upward through the transmission when it is driven by the movement of the chain 8, triggering the elastic component at the same time. The elastic component can then drive the lever 43 to reset. At the same time, after the lever 43 rotates, the piston 31 will rise and open the oil nozzle 28. The lever 43 will reset after it is unobstructed, and the elastic component will drive the piston 31 to move downward quickly to spray the lubricating oil through the oil nozzle 28.

[0047] As a preferred implementation in this embodiment, Figure 8 、 Figure 9 and Figure 10 As shown, the diameter of the second gear 42 is greater than that of the first gear 41 , and the lower end corner of the shifting rod 43 is arc-shaped.

[0048] This structure allows the first gear 41 to rotate at an increased speed when the second gear 42 drives the first gear 41 to rotate, thereby allowing the toothed plate 36 to drive the piston block 31 to move up and down more quickly. At the same time, the arc-shaped corner design at the lower end of the shifting rod 43 can avoid unnecessary scratches and wear when contacting the chain 8.

[0049] Working principle: when in use, the first screw 12 can be controlled to rotate forward and reverse by starting the second motor 11, so that the first screw sleeve 13 drives the connecting frame 14 to move laterally through the thread action, and the connecting frame 14 will drive the right rotating shaft 5 to move laterally along the slide 3 using the slide seat 4 through the connecting sleeve 16, thereby changing the tension of the sprocket 7 on the chain 8. At the same time, the non-contact temperature sensor 15 can be used to detect the temperature of the chain 8 and the chain plate 9 removed from the heat treatment equipment during use. If the temperature is too high due to the heat treatment equipment or the chain 8 and the chain plate 9 expand and contract after cooling, the displacement can be compensated by starting the second motor 11 to move the sprocket 7, so as to control the tension within an appropriate range to protect the equipment.

[0050] When oiling is needed, the electric push rod 18 and the liquid pump 27 are started, so that the electric push rod 18 drives the connecting rod 19 downward, and the connecting rod 19 moves downward along the guide rod 21 through the guide hole 20, so that the shift rod 43 can be inserted into the roller gap of the chain 8, and the oil nozzle 28 is aligned with the gap between the roller, sleeve and pin of the chain 8. Then the first motor 6 can be started, so that the first motor 6 drives the rotating shaft 5 to rotate, so that the sprocket 7 drives the chain 8 to rotate and start running, so that the chain 8 The upper side of the chain 8 moves slowly toward the right, while the lower side of the chain 8 moves slowly toward the left. The lever 43 rotates when the chain 8 moves toward the left, and drives the second gear 42 to rotate. The second gear 42 drives the toothed plate 36 through the first gear 41 to move upward along the slide 38 through the ball 39 through the slider 37, and the connecting block 35 drives the second screw 29 and the piston rod 30 to move upward. At the same time, the piston block 31 moves upward in the oiling cylinder 23, and the second screw sleeve 33 The spring 32 moves upward to squeeze the spring 32, and when the spring 32 moves upward to a certain extent, the inner opening of the connecting port 24 will open. At this time, the liquid pump 27 injects the lubricating oil in the oil barrel 26 into the bottom side of the oil filling cylinder 23 through the connecting hose 25. After the lever 43 rotates to the roller of the chain 8, it will not be restricted. Therefore, the spring 32 will push the second screw sleeve 33 downward through the restoring force, causing the connecting block 35 and the piston block 31 to move downward, and the connecting block 35 will drive the first screw sleeve 33 to move downward through the tooth plate 36. The gear 41 reverses, and the first gear 41 drives the lever 43 to reverse and reset to the gap between the next set of rollers through the second gear 42. When the piston block 31 moves downward, the lower side lubricating oil is squeezed and sprayed out through the oil nozzle 28, so that the lubricating oil is sprayed into the gaps between the rollers, sleeves, pins and other parts, thereby achieving lubrication. After lubrication is completed, the liquid pump 27 is turned off and the electric push rod 18 is started, so that the lever 43 and the oil nozzle 28 are both lifted, and then the equipment can work normally.
