Description

Technical Field

[0001] This utility model relates to the field of umbrella pole processing technology, and in particular to a fixing device for umbrella pole processing. Background Technology

[0002] An umbrella is a tool for providing shade or protection from rain and snow. It is generally made of oiled paper, oilcloth, or plastic sheeting. The umbrella ribs are the individual frames that support the umbrella. In the past, most umbrella ribs were made of wood or bamboo. Later, iron, steel, electroplated, and resin ribs appeared. Most umbrellas are now designed with collapsible ribs, making them lightweight and convenient to carry. The umbrella shaft is a very important component of the umbrella and involves multiple processing steps. During the production process, the umbrella shaft needs to be fixed and supported.

[0003] For example, Chinese utility model patent CN220637545U provides an umbrella pole support and fixing device. This device includes a base, a frame fixedly mounted on the top of the base, a circular hole in a rectangular groove on the upper surface of the frame, a sliding column fixedly mounted on the lower surface of the frame, dovetail grooves at both ends of the upper surface of the frame, and fixing blocks fixedly mounted on the side walls of the frame. To better support and fix the umbrella pole vertically, this device incorporates a moving mechanism. When a hydraulic cylinder is activated, it works in conjunction with a piston rod, a cylinder, and a long rod, causing the long rod to push the dovetail sliders closer together within the dovetail grooves. This causes the rectangular plates to move closer together, clamping and fixing the umbrella pole fixed in the circular hole. Furthermore, the sliding sleeve, cylinder, and short rod allow the rectangular plates on both sides to move synchronously.

[0004] While the aforementioned device can effectively fix the umbrella pole in the vertical direction and ensure its stability in that direction, the actual processing requirements for the umbrella pole go far beyond this. Due to the complexity of the production process, the umbrella pole often needs to undergo precision processing operations such as drilling and grinding at multiple angles. These operations not only require the umbrella pole to be stably fixed, but also require the angle to be flexibly adjusted to adapt to the needs of different processes. Therefore, simply fixing the umbrella pole in a single direction is obviously insufficient and has significant limitations, making it difficult to meet the diverse needs of actual production. Utility Model Content

[0005] This utility model discloses a fixing device for processing umbrella poles, which solves the problem that traditional fixing devices for processing umbrella poles can only fix the umbrella pole in one direction, which is limited.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A fixing device for processing umbrella poles includes a horizontally arranged worktable. A vertical support column is movably mounted on the top surface of the worktable. A first drive assembly is provided on the worktable to drive the support column to move horizontally along the worktable. A movable block is slidably connected to the support column. A cylinder is provided on the support column to drive the movable block to move up and down along the support column. A horizontal rotating shaft is rotatably connected to the movable block. Both ends of the rotating shaft pass through the movable block and extend outside the movable block. A stepper motor is provided on the movable block to drive the rotating shaft to rotate around its own axis. A horizontal support plate is fixed to the end of the rotating shaft away from the stepper motor. Two symmetrical and horizontal clamping plates are movably mounted inside the support plate. The ends of the two clamping plates away from the rotating shaft pass through the support plate and extend outside the support plate. A second drive assembly is provided on the support plate to drive the ends of the two clamping plates outside the support plate to move closer or further apart.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The height of the entire support plate is adjusted by first using a cylinder to drive the movable block to move up and down along the support column, ensuring that the bottom end of the umbrella rod does not collide with the top surface of the worktable when the two clamping plates hold the umbrella rod. The center of the umbrella rod to be processed is placed between the two clamping plates, and the second drive assembly drives the ends of the two clamping plates outside the support plate to move closer together, thus fixing the umbrella rod in a completely vertical position. When it is necessary to process the umbrella rod horizontally or diagonally, the stepper motor is started. The output end of the stepper motor drives the rotating shaft to rotate around its own axis, which in turn drives the entire support plate to rotate, thereby adjusting the umbrella rod from the initial vertical fixed state to a diagonal or horizontal fixed state. In actual production, the height of the umbrella rod during processing can be adjusted using a cylinder, and the first drive assembly can be used to drive the support column to move horizontally along the worktable, thereby controlling the horizontal position of the umbrella rod. This invention boasts a high degree of automation and practicality. By incorporating a support plate, clamping plate, and a second drive assembly, it can securely clamp umbrella poles of varying diameters. Furthermore, by including a movable block, stepper motor, and rotating shaft, it can meet the multi-angle processing requirements of the umbrella poles. Additionally, the invention includes a cylinder, support column, and a first drive assembly, enabling control of the umbrella pole's vertical and horizontal positions, significantly enhancing the flexibility and applicability of the umbrella pole during processing.

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a fixing device for processing umbrella poles, including a horizontally arranged workbench 1, a vertical support column 2 movably mounted on the top surface of the workbench 1, a first driving assembly for driving the support column 2 to move horizontally along the workbench 1 on the workbench 1; a movable block 3 slidably connected to the support column 2, and a cylinder 31 for driving the movable block 3 to move up and down along the support column 2 on the support column 2; a horizontal rotating shaft 4 rotatably connected to the movable block 3, both ends of the rotating shaft 4 passing through the movable block 3 and extending outside the movable block 3, and a stepper motor 41 for driving the rotating shaft 4 to rotate around its own axis on the movable block 3; a horizontal support plate 5 is fixed to the end of the rotating shaft 4 away from the stepper motor 41, and two symmetrical and horizontal clamping plates 51 are movably mounted inside the support plate 5, the ends of the two clamping plates 51 away from the rotating shaft 4 passing through the support plate 5 and extending outside the support plate 5, and a second driving assembly for driving the ends of the two clamping plates 51 located outside the support plate 5 to move closer or further away from each other.

[0017] like Figure 2As shown, the second drive assembly includes an automatic push rod 52 horizontally fixed inside the support plate 5. The output end of the automatic push rod 52 is fixed with a horizontal push block 53, and the push block 53 is slidably connected to the inner bottom surface of the support plate 5. A rack 54 is fixed on both sides of the push block 53, and the two racks 54 are symmetrically arranged. Two vertical fixed shafts 55 are also fixed inside the support plate 5, located on both sides of the push block 53. A gear 56 that meshes with the corresponding rack 54 is rotatably connected to each fixed shaft 55. The center of each gear 56 is fixedly connected to one end of the corresponding clamping plate 51 inside the support plate 5, and one end of each clamping plate 51 inside the support plate 5 is rotatably connected to the corresponding fixed shaft 55. The support plate 5 has an inner cavity 57 for the automatic push rod 52, push block 53, rack 54, gear 56 and clamping plate 51 to move. When the automatic push rod 52 is activated, its output end drives the push block 53 to move horizontally within the support plate 5. This, in turn, drives the corresponding gears 56 to rotate via two racks 54, with the two gears rotating in opposite directions. This causes the two clamping plates 51 to rotate around their ends located within the support plate 5, while the ends of the two clamping plates 51 located outside the support plate 5 move closer to or further away from each other, thus clamping and fixing umbrella poles of different diameters. Furthermore, both clamping plates 51 are fixed to the top surface of their corresponding gears 56, preventing them from colliding with the push block 53 and racks 54 during rotation, thus preventing any impact on the fixing of the umbrella pole. Even further, a rechargeable battery can be installed within the support plate 5 to provide power to the automatic push rod 52; or the output end of the stepper motor 41 can be adjusted to reciprocate to prevent the wires of the automatic push rod 52 from becoming tangled.

[0018] like Figure 2 As shown, the two clamping plates 51 are provided with anti-slip pads 511 on opposite sides outside the support plate 5, and the surface of the anti-slip pads 511 is provided with anti-slip protrusions 512. The anti-slip pads 511 and anti-slip protrusions 512 can improve the stability of the two clamping plates 51 when clamping the umbrella pole, so as to fix the umbrella pole more firmly.

[0019] like Figure 4 As shown, the first drive assembly includes a motor 6 horizontally fixed within the worktable 1. A horizontal lead screw 61 is fixed to the output end of the motor 6. The lead screw 61 is located within the worktable 1 and rotatably connected to it. A slider 62, whose top surface is fixed to the bottom surface of the support column 2, is threaded onto the lead screw 61. A cavity 11 is provided within the worktable 1 for the movement of the motor 6, the lead screw 61, and the slider 62. When the motor 6 is started, its output end drives the lead screw 61 to rotate around its own axis, which in turn drives the support column 2 to move horizontally along the lead screw 61 via the slider 62, thereby controlling the horizontal position of the umbrella handle.

[0020] like Figure 3As shown, the support column 2 has a side groove 21 for the movement of the cylinder 31 and the movable block 3. The cylinder 31 is fixed to the inner bottom surface of the side groove 21. Slide rails 22 are fixed on both sides of the side groove 21. Slide grooves corresponding to the slide rails 22 are opened on both sides of the movable block 3. The movable block 3 is slidably connected to the support column 2 through the slide rails 22 and slide grooves. By setting the slide rails 22 and slide grooves (not shown in the figure), the movement of the movable block 3 can be guided, thus making it easier for the movable block 3 to move up and down along the support column 2.

[0021] like Figure 1 and Figure 3 As shown, a mounting base 42 is fixed on the side of the movable block 3 facing away from the support plate 5, and the mounting base 42 is fixedly connected to the fixed end of the stepper motor 41. The mounting base 42 can fix and support the stepper motor 41.

[0022] like Figure 1 As shown, several supports 7 are fixed to the bottom surface of the workbench 1. The supports 7 can support the entire device, making the entire device more convenient to use.

[0023] In use, the cylinder 31 drives the movable block 3 to move up and down along the support column 2 beforehand, thereby adjusting the height of the entire support plate 5 so that the bottom end of the umbrella rod will not collide with the top surface of the workbench 1 when the two clamping plates 51 hold the umbrella rod. The center of the umbrella rod to be processed is placed between the two clamping plates 51, and the automatic push rod 52 is activated. The output end of the automatic push rod 52 can drive the push block 53 to move horizontally within the support plate 5, which in turn drives the corresponding gears 56 to rotate through the two racks 54, making the rotation directions of the two gears 56 opposite, thereby causing the two clamping plates 51 to rotate around the end located inside the support plate 5. The two clamping plates 51 are located outside the support plate 5. One end moves closer to the other or further away, thus clamping and fixing umbrella poles of different diameters, with the umbrella pole in a completely vertical position. When the umbrella pole needs to be processed horizontally or diagonally, the stepper motor 41 is started. The output end of the stepper motor 41 drives the rotating shaft 4 to rotate around its own axis, which in turn drives the entire support plate 5 to rotate, thereby adjusting the umbrella pole from its initial vertical fixed state to a diagonal or horizontal fixed state. In actual production, the height of the umbrella pole during processing can be adjusted using the cylinder 31, and the support column 2 can be moved horizontally along the worktable 1 using the motor 6, thereby controlling the horizontal position of the umbrella pole.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
