Description

Technical Field

[0001] This invention belongs to the field of grease spraying technology for electric limit switch transmission mechanisms, specifically a grease spraying system for electric limit switch transmission mechanisms. Background Technology

[0002] Existing grease spraying processes for electric limit switch transmission components mostly involve manual application of lubricating grease, making it impossible to monitor the amount and effectiveness of grease application. This results in excessive resistance during automatic or manual opening or closing of the electric limit switch, affecting the user experience. Furthermore, excessive grease application can cause the grease to solidify in extremely cold weather, leading to malfunctions in the opening or closing function. Insufficient grease can also cause excessive noise or abnormal sounds during daily use, further impacting the user experience. Therefore, we propose a grease spraying system for electric limit switch transmission mechanisms. Summary of the Invention

[0003] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a grease spraying system for electric limit switch transmission mechanisms. This system effectively solves the problems of existing electric limit switch transmission component assembly grease spraying processes, which mostly rely on manual application of lubricating grease, making it impossible to monitor the amount and effect of grease application. This results in excessive resistance during automatic or manual opening or closing of the electric limit switch, affecting the user experience. Furthermore, excessive grease application can cause the grease to solidify in extremely cold weather, leading to malfunctions in opening or closing functions, while insufficient grease can cause excessive noise or abnormal sounds during daily use, also impacting the user experience.

[0025] like Figure 1-5As shown, the present invention provides a technical solution: an electric limit switch transmission mechanism grease spraying system, including an oil injection module 100, a fixing module 200, a product drive module 300 and a program drive module 400.

[0026] The oil injection module 100 includes a flow meter 2, an oil supply booster valve 5, an oil injection valve 6, and a large equipment plate 8. The oil outlet pipe of the oil supply booster valve 5 is connected to the oil inlet pipe of the flow meter 2, and the oil outlet pipe of the flow meter 2 is connected to the oil inlet pipe of the oil injection valve 6. The flow meter 2, the oil supply booster valve 5, and the oil injection valve 6 are all fixedly installed on the front side of the large equipment plate 8.

[0027] The fixing module 200 includes a fixing fixture 3. Two sets of guide rods 31 are evenly fixed on the top of the fixing fixture 3. A first sliding seat 33 and a second sliding seat (34) are slidably sleeved on the outer side of the two sets of guide rods 31. The first sliding seat 33 is located to the left of the second sliding seat 34. A telescopic cylinder 32 is fixed on the top of the fixing fixture 3. The right side of the telescopic end of the telescopic cylinder 32 is connected to the left side of the first sliding seat 33. The telescopic cylinder 32 drives the first sliding seat 33 to move left and right. Material placement slots are opened through the right sides of both the first sliding seat 33 and the second sliding seat 34. A set of limiting blocks 35 are fixed on both the front and rear sides of the inner side wall of the material placement slot of the second sliding seat 34. A rotary cylinder 36 is fixed on the top of the first sliding seat 33. A limiting plate 37 is fixed on the left side of the telescopic end of the rotary cylinder 36. The limiting plate 37 is located to the left of the first sliding seat 33.

[0028] The product drive module 300 includes a spline sleeve 7 and a motor 71. A coupling is provided on the left side of the output end of the motor 71, and a spline sleeve 7 is provided on the left side of the rotating shaft of the coupling. The spline sleeve 7 is located on the right side of the second sliding seat 34. The motor 71 and the coupling are both located on the top of the fixed fixture 3.

[0029] The program drive module 400 includes a display screen 1 and a start button 4. The display screen 1 and the start button 4 are electrically connected. Both the display screen 1 and the start button 4 are electrically connected to the electrical equipment in the oil filling module 100, the fixing module 200 and the product drive module 300.

[0030] The equipment frame 9 is placed on the outer wall of the fixed fixture 3. Both the fixed fixture 3 and the start button 4 are fixedly installed at the bottom of the inner cavity of the equipment frame 9.

[0031] The inner cavity of the equipment frame 9 is fixedly equipped with an electrically controlled transverse moving track 11 by a bracket. An electric retractable rod 81 is fixedly installed at the top of the moving end of the electrically controlled transverse moving track 11. The large equipment plate 8 is fixedly installed on the front side of the telescopic end of the electric retractable rod 81. The electric retractable rod 81 drives the large equipment plate 8 to move up and down, and the electrically controlled transverse moving track 11 drives the large equipment plate 8 to move left and right.

[0032] The fuel injection valve 6 corresponds to the first sliding seat 33 and the second sliding seat 34. The fuel injection valve 6, the first sliding seat 33, the second sliding seat 34 and the spline sleeve 7 are on the same coronal surface.

[0033] A method for using a grease spraying system for an electric limit switch transmission mechanism:

[0034] Step 1: The operator selects the corresponding vehicle model formula on the display screen 1, and then inserts the product into the material placement slots of the first sliding seat 33 and the second sliding seat 34. At this time, the screw support sleeve on the right side of the material is located on the left side of the first sliding seat 33, and the threaded sleeve on the outside of the material and the rocker arm rotatably connected below it are located in the material placement slot of the second sliding seat 34. At the same time, the limiting block 35 limits the left side of the threaded sleeve on the outside of the material. The start button 4 is activated, and the rotating cylinder 36 drives the limiting plate 37 to flip forward and press against the left side of the screw support sleeve on the right side of the material. The telescopic cylinder 32 pushes the first sliding seat 33 to the left, thereby driving the material and the second sliding seat 34 to the left. When the right spline of the screw part in the material is inserted into the spline sleeve 7, the telescopic cylinder 32 stops working.

[0035] Step 2: Connect the oil pipe of the external oil supply device to the oil supply booster valve 5. The electric retraction rod 81 drives the equipment plate 8 and the oil supply booster valve 5, flow meter 2 and oil injection valve 6 in front of the equipment plate 8 to move downwards and approach the material to be tested. The oil supply booster valve 5 delivers grease to the flow meter 2 and oil injection valve 6, and finally sprays it out from the oil injection valve 6. When the grease enters the flow meter 2, it will drive the internal gear assembly of the flow meter 2 to rotate, thereby converting it into pulse count. Finally, the PLC program inside the flow meter 2 is connected to calculate the actual oil output, thereby achieving the purpose of grease monitoring.

[0036] Step 3: While the oil injection valve 6 is spraying oil, the electronically controlled transverse moving track 11 drives the large plate 8 of the equipment and the oil injection valve 6 in front of it to move left and right, so that the grease is evenly sprayed onto the screw part of the material to be tested. At the same time, the motor 71 drives the spline sleeve 7 to rotate through the coupling, which in turn drives the spline part on the right side of the material screw part to rotate, thus driving the material screw part to rotate. When the material screw part rotates, it will drive the threaded sleeve screwed to its outside to move. Since the threaded sleeve is locked in the material placement groove of the second sliding seat 34, the threaded sleeve will move left and right, which in turn drives the rocker arm below the threaded sleeve to move left and right.
