Description

Technical Field

[0001] This utility model relates to the field of silicone grease application equipment technology, and in particular to a semi-automatic silicone grease application equipment. Background Technology

[0002] In the military, aviation, and aerospace industries, the application of silicone grease to cylindrical products is crucial. Currently, manual application dominates the technology for silicone grease application, but this method has several serious drawbacks: Firstly, the accuracy and uniformity of silicone grease application cannot be effectively guaranteed. When using a brush, it is difficult to precisely control the amount of silicone grease used. Furthermore, due to the limitations of manual operation, it is impossible to ensure that the thickness of the grease is uniform across all parts of the product, thus affecting the product's performance. Secondly, manual application of silicone grease poses high safety risks. Some cylindrical products are heavy and have a cylindrical shape, requiring continuous contact with the product during manual application, which greatly increases the risk of the product falling. Additionally, as silicone grease is a mixture containing various elements, excessive contact may harm human health. Therefore, it is necessary to design a device that can replace manual application of silicone grease to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a semi-automatic silicone grease application device, which has the advantages of good silicone grease application effect and reduced safety risks associated with manual silicone grease application.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a semi-automatic silicone grease application device, including a base; a positioning support component for positioning and supporting a workpiece is fixedly connected to the base, and a lifting seat is slidably connected to the base in the vertical direction based on a lifting and sliding component; a workpiece driving component for driving the workpiece to rotate and a coating component for applying silicone grease to the surface of the workpiece are fixedly connected to the lifting seat based on an adjustment component.

[0005] The present invention is further configured such that: the positioning support assembly includes a fixed end positioning support assembly fixedly connected to the base for positioning one end of the workpiece, and a floating end positioning support assembly slidably connected to the base based on a horizontal slide rail for positioning the other end of the workpiece; the fixed end positioning support assembly includes a fixed seat fixedly connected to the base and a fixed end support wheel symmetrically rotatably connected to the fixed seat for supporting the workpiece; the fixed seat is adjustable along a direction parallel to the center line of the workpiece and has a fixed end positioning wheel for abutting the fixed end of the workpiece; the floating end positioning support assembly includes a sliding seat slidably connected to the horizontal slide rail along a direction parallel to the center line of the workpiece and a floating end support wheel symmetrically rotatably connected to the sliding seat for supporting the workpiece; the sliding seat is slidably connected based on a slide cylinder and has a floating end positioning wheel for abutting the floating end of the workpiece.

[0006] The present invention is further configured such that: a plurality of first adjustment holes are provided on the fixed base along the direction parallel to the center line of the workpiece; an adjustment seat for installing the fixed end positioning wheel is slidably connected on the mounting base; a plurality of second adjustment holes are provided on the adjustment seat to cooperate with the first adjustment holes; and the first adjustment holes and the second adjustment holes are connected by a plug rod.

[0007] The present invention is further configured such that: a proximity sensor is fixedly provided on the adjustment seat to prevent damage to the end face of the workpiece.

[0008] The present invention is further configured such that: the lifting and sliding assembly includes a support frame fixedly connected to the base and a vertical slide rail symmetrically fixedly connected to the support frame along the vertical direction; the lifting seat is slidably connected to the vertical slide rail along the vertical direction; and a lifting cylinder for driving the lifting seat to lift is fixedly connected to the base along the vertical direction.

[0009] The present invention is further configured such that: the workpiece driving assembly includes a drive motor fixedly connected to the base and a workpiece driving wheel fixedly connected to the drive motor for abutting against the workpiece axial surface to drive the workpiece to rotate.

[0010] The present invention is further configured such that the workpiece drive wheel is a polyurethane-coated roller.

[0011] The present invention is further configured such that: the adjustment assembly includes an X-axis precision adjustment slide fixedly connected to the lifting seat in the horizontal direction and a Z-axis precision adjustment slide fixedly connected to the X-axis precision adjustment slide in the vertical direction; the application assembly includes a sliding end fixedly connected to the Z-axis precision adjustment slide in the vertical direction, a silicone grease screw valve for precisely controlling the amount of silicone grease extruded, and a silicone grease scraper fixedly connected to the bottom of the silicone grease screw valve for uniformly scraping silicone grease onto the surface of the workpiece.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. The fixed-end positioning component and the floating-end positioning component use fixed-end support wheels and floating-end support wheels to support and position the workpiece's axial surface, ensuring that the workpiece's centerline is horizontal. The fixed-end positioning wheels and floating-end positioning wheels also position the two ends of the workpiece. After the workpiece is positioned, the lifting and sliding component drives the workpiece drive component to descend, thereby driving the workpiece to rotate at a constant speed by having the workpiece drive wheel contact the workpiece's axial surface. This avoids the risk of uneven silicone grease application caused by product slippage due to traditional belt drives. The application component uses a silicone grease screw valve with a silicone grease scraper at the bottom. The silicone grease screw valve allows for precise adjustment of the amount of silicone grease used, and the silicone grease scraper ensures that the silicone grease is evenly applied to the workpiece surface, guaranteeing uniform silicone grease application and eliminating the need for manual silicone grease application, thus reducing the safety risks associated with manual silicone grease application.

[0014] 2. The fixed-end positioning support assembly achieves rapid adjustment of the position of the adjusting seat on the fixed seat by opening several first adjustment holes on the fixed seat and second adjustment holes on the adjusting seat that cooperate with the first adjustment holes. At the same time, the floating-end positioning support assembly is slidably connected to the base through a horizontal slide rail. By adjusting the position of the sliding seat on the horizontal slide rail, it can adapt to the floating end positioning requirements of workpieces of different lengths, thus achieving adaptation to workpieces of different specifications. Meanwhile, the application assembly is fixedly connected to the lifting seat through the adjusting assembly. The adjusting assembly, by setting X-axis precision adjusting slide and Z-axis precision adjusting slide, can accurately adjust the application position and thickness of the silicone grease, thus adapting to the application requirements of silicone grease for different workpieces.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] refer to Figures 1 to 4 A semi-automatic silicone grease application device includes a base 1, a positioning support component 2 for positioning and supporting a workpiece fixedly connected to the base 1, and a lifting seat 4 slidably connected to the base 1 in the vertical direction based on a lifting and sliding component 3. A workpiece drive component 5 for driving the workpiece to rotate and an application component 7 for applying silicone grease to the surface of the workpiece are fixedly connected to the lifting seat 4 based on an adjustment component 6.

[0023] refer to Figure 2 and Figure 4Specifically, the positioning support assembly 2 includes a fixed-end positioning support assembly 21 fixedly connected to the base 1 for positioning one end of the workpiece, and a floating-end positioning support assembly 23 slidably connected to the base 1 based on a horizontal slide rail 22 for positioning the other end of the workpiece. The fixed-end positioning support assembly 21 includes a fixed base 211 fixedly connected to the base 1 and a fixed-end support wheel 212 symmetrically rotatably connected to the fixed base 211 for supporting the workpiece. The fixed base 211 is adjustable along a direction parallel to the center line of the workpiece, and the fixed-end positioning wheel 213 is provided to abut against the fixed end of the workpiece. The floating-end positioning support assembly 23 includes a slidably connected... A sliding seat 231 on the horizontal slide rail 22 and a floating end support wheel 232 symmetrically rotatably connected to the sliding seat 231 to support the workpiece are provided. A floating end positioning wheel 234 for abutting the floating end of the workpiece is slidably connected to the sliding seat 231 based on the slide cylinder 233. When positioning the workpiece, the workpiece is first placed on the fixed end support wheel 212 and the floating end support wheel 232, thus initially positioning the workpiece's central axis along the horizontal direction. Subsequently, the cylinder slide table drives the floating end positioning wheel 234 to abut one end of the workpiece, pushing the fixed end of the workpiece against the fixed end positioning wheel 213, thereby achieving positioning of both ends of the workpiece. Based on this, the workpiece positioning is completed. For complete positioning, a plurality of first adjustment holes 214 are provided on the fixed base 211 along a direction parallel to the center line of the workpiece. An adjustment seat 215 for mounting the fixed end positioning wheel 213 is slidably connected to the mounting base. The adjustment seat 215 has a plurality of second adjustment holes 216 that cooperate with the first adjustment holes 214. The first adjustment holes 214 and the second adjustment holes 216 are connected by a plug rod 217. By providing a plurality of first adjustment holes 214 on the fixed base 211 and second adjustment holes 216 on the adjustment seat 215 that cooperate with the first adjustment holes 214, the position of the adjustment seat 215 on the fixed base 211 can be quickly adjusted to achieve rapid positioning of the fixed end of the workpiece. The floating end positioning support component 23 is slidably connected to the base 1 via the horizontal slide rail 22. By adjusting the position of the sliding seat 231 on the horizontal slide rail 22, the floating end positioning requirements of workpieces of different lengths can be met, thus enabling adaptation to workpieces of different specifications. After the floating end positioning support component 23 is adjusted, it is fixed to the base 1 by the locking block. A proximity sensor is fixed on the adjusting seat 215 to avoid damage to the end face of the workpiece. The contact sensor is coupled to the slide cylinder 233. When the workpiece approaches, the sliding speed of the slide cylinder 233 is reduced to avoid collision between the workpiece and the fixed seat 211, thereby preventing damage to the end face of the workpiece.

[0024] refer to Figure 1 and Figure 3Specifically, the lifting and sliding assembly 3 includes a support frame 31 fixedly connected to the base 1 and a vertical slide rail 32 symmetrically fixedly connected to the support frame 31 along the vertical direction. The lifting seat 4 is slidably connected to the vertical slide rail 32 along the vertical direction. A lifting cylinder 33 is fixedly connected to the base 1 along the vertical direction to drive the lifting seat 4 to move up and down. The lifting cylinder 33 drives the lifting seat 4 to slide vertically on the vertical slide rail 32, thereby driving the workpiece driving assembly 5 and the coating assembly 7 to move up and down. The workpiece driving assembly 5 includes a drive motor 51 fixedly connected to the base 1 and a workpiece driving wheel 52 fixedly connected to the drive motor 51 for abutting the workpiece shaft surface to drive the workpiece to rotate. After the workpiece is positioned, the lifting and sliding assembly 3 drives the workpiece driving assembly 5 to descend, thereby realizing that the workpiece is directly driven to rotate at a uniform speed by the workpiece driving wheel 52 abutting the workpiece shaft surface, avoiding the risk of uneven silicone grease application caused by product slippage due to traditional belt drive. The workpiece driving wheel 52 uses a rubber-coated wheel to improve the contact effect. In this embodiment, the workpiece drive wheel 52 uses a polyurethane-coated roller with an overpressure of 0.5mm to prevent slippage of the workpiece during rotation due to insufficient static friction, which would affect the silicone grease application effect.

[0025] refer to Figure 3 Specifically, the adjustment component 6 includes an X-axis precision adjustment slide 61 fixedly connected to the lifting seat 4 in the horizontal direction and a Z-axis precision adjustment slide 62 fixedly connected to the X-axis precision adjustment slide 61 in the vertical direction. The application component 7 includes a silicone grease screw valve 71 fixedly connected to the sliding end of the Z-axis precision adjustment slide in the vertical direction for precisely controlling the amount of silicone grease extruded, and a silicone grease scraper 72 fixedly connected to the bottom of the silicone grease screw valve 71 for uniformly scraping the silicone grease onto the surface of the workpiece. The adjustment component 6 achieves precise adjustment of the application position and thickness of the silicone grease by setting the X-axis precision adjustment slide 61 and the Z-axis precision adjustment slide 62, thereby adapting to the silicone grease application requirements of different workpieces. The silicone grease screw valve 71 achieves precise adjustment of the amount of silicone grease used, and the silicone grease scraper 72 achieves uniform application of the silicone grease onto the surface of the workpiece, ensuring the uniformity of the silicone grease application.

[0026] Brief description of the usage process: First, the workpiece is placed on the fixed end support wheel 212 and the floating end support wheel 232, so that the central axis of the workpiece is initially positioned in the horizontal direction. Then, the cylinder slide table drives the floating end positioning wheel 234 to abut against one end of the workpiece, so that the fixed end of the workpiece abuts against the fixed end positioning wheel 213, thereby realizing the positioning of both ends of the workpiece. After the workpiece is positioned, the lifting and sliding assembly 3 drives the workpiece driving assembly 5 to descend, so that the workpiece driving wheel 52 abuts against the workpiece shaft surface, thereby directly driving the workpiece to rotate at a constant speed. At the same time, the silicone grease screw valve 71 evenly squeezes out a certain amount of silicone grease to the surface of the workpiece, and the silicone grease scraper 72 evenly spreads the silicone grease on the surface of the workpiece.
