Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and more specifically to a fixing device for rotatable components. Background Technology

[0002] When assembling rotatable components, they usually need to be rotated to a specific angle and then positioned and fixed. The way of rotation and fixing not only directly affects the precision control and efficiency of the assembly process, but also plays a key role in the subsequent functional realization and the overall structural stability. Therefore, optimizing this operation process is of great significance for improving assembly quality.

[0003] like Figure 1 The image shows a commonly used double-section speed-regulating bracket 1 in the general machinery industry, including a hinge part 11, and bracket one 12 and bracket two 13 connected by a rotating part 11, which can move along... Figure 1 The curved arrow indicates the direction of the limited rotation. When installing the speed control bracket and adjusting the throttle clearance, operators typically rely solely on manual operation without any other assistance. In this situation, they must simultaneously control the rotation of the speed control arm and the speed control bracket 12, while also ensuring the hinge of the double-section speed control bracket is in a rigid, straight state (keeping 13 taut). The numerous factors involved increase the difficulty of operation and reduce the first-pass yield rate. Utility Model Content

[0004] The present invention aims to provide a fixing device for rotatable components, assisting operators in completing the fixing operation after the rotatable components are rotated, reducing control factors in the fixing operation process, reducing the difficulty of operation for operators, ensuring operation accuracy, and improving the assembly qualification rate.

[0005] The basic solution provided by this utility model is: a fixing device for rotatable components, including a support;

[0006] The bottom of the support is provided with a first groove; the first side of the support is provided with a second groove;

[0007] A quick-clamp assembly is installed on the second side of the support; the second side is adjacent to the first side and its direction on the support is consistent with the opening direction of the first groove; the quick-clamp assembly includes a body and a head, the head is installed at an adjustable distance on the bottom of the body; the head has an inclined structure at least on the side opposite to the opening of the first groove; the body has a moving operation structure to drive the head to move up and down.

[0008] The working principle and advantages of this utility model are as follows: the groove structure, specific opening orientation, angle difference, and height difference of the first and second grooves are adapted to the structure of the rotatable component and the rotation direction and angle of the component when fixing the rotatable component. In use, first adjust the distance between the quick-clamp assembly body and the head, and simultaneously move the head through the body's moving mechanism to a position that does not interfere with the rotatable component's insertion into the groove; then, use the second groove to clamp one end of the component, rotate the component towards the opening of the first groove, use the first groove to clamp the other end of the component, and after the first groove clamps the component, use the body's moving mechanism to move the head, with the head's inclined surface contacting the component, further tightening the component while the first groove clamps it; if the head needs to be replaced, it can be disassembled from the body and replaced directly.

[0009] Compared with existing technologies, the fixing device designed in this scheme has the following advantages when fixing rotatable components:

[0010] 1) It can help operators quickly and accurately control the rigid fixation of the component after rotation. In particular, it can be used to control the hinge part of the double-section speed-regulating bracket to be in a rigid straight state, reducing the control factors in the process of direct hand operation by the operator, reducing the difficulty of operation, improving the efficiency of operation, ensuring the fixation accuracy, and indirectly improving the pass rate.

[0011] 2) Based on the second and first grooves clamping the rotatable component, the quick-clamp assembly is used to further reinforce the clamping of the rotatable component, thereby improving the fixing stability;

[0012] 3) The body and head of the quick clamp assembly are designed with adjustable spacing to adjust the stroke of vertical movement; at the same time, the head is designed with an inclined structure to ensure linear control of the clamping force of the component while adjusting the stroke vertically. This can accommodate slight changes in the size of components from different production batches of the supplier, and can also accommodate different operators' practical skills, with great fault tolerance.

[0013] 4) The quick-clamp assembly is designed with both the main body and the head as detachable, which makes assembly convenient and provides great convenience, especially during maintenance and replacement. In addition, when the head is damaged, only the head needs to be replaced, which is much more advantageous in terms of economic cost and supplier production cycle compared to replacing the whole assembly.

Detailed Implementation

[0018] The following detailed explanation illustrates the specific implementation methods:

[0019] The basic implementation examples are as follows: Figure 2 As shown: A fixing device for rotatable components, including a support 2;

[0020] The bottom of the support 2 is provided with a first groove 211; the first side of the support 2 is provided with a second groove 221; wherein, the groove structure, specific opening orientation, angle difference and height difference relative to the support of the first groove 211 and the second groove 221 are adapted to the structure of the rotatable component and the rotation direction and rotation angle of the component when the rotatable component is fixed.

[0021] A quick-clamp assembly is installed on the second side of the support 2; the second side is adjacent to the first side and its direction on the support is consistent with the opening direction of the first groove 211; the quick-clamp assembly includes a body and a head 6, the head 6 is adjustable and detachably installed on the bottom of the body; the head 6 has an inclined structure at least on the side opposite to the opening of the first groove 211; the body has a moving operation structure to drive the head 6 to move up and down.

[0022] To better indicate the direction, Figure 2 The opening of the first groove 211 faces horizontally forward, and the opening of the second groove 221 faces vertically downward.

[0023] In this embodiment, the rotatable component is Figure 1 The double-section speed-regulating bracket 1 shown has a hinge part 11, a bracket 12 and a bracket 2 13. The bracket 12 and the bracket 2 13 have a long strip structure. When fixed, it is necessary to control the hinge part 11 of the double-section speed-regulating bracket 1 to be in a rigid straight line state. At this time, the bracket 12 and the bracket 2 13 are parallel.

[0024] In this embodiment, the support 2 is designed based on the component structure of the double-section speed-regulating bracket 1; as follows: Figure 2 As shown, the support 2 includes a fixing plate 23, a fixing block 21 installed at the bottom of the fixing plate 23, and an extension 22 installed on the first side of the fixing plate 23.

[0025] The height of the fixed plate 23 (with) Figure 2The vertical dimension is defined as 85-95mm, preferably 92mm, and the thickness of the fixing plate 23 is 3-6mm, preferably 4mm, so that the support 2 meets the structural strength requirements, ensures that the overall size of the fixing device matches the component, the size is reasonable, and it is easy to operate, while also ensuring that the movement stroke is reasonable when the quick clamp assembly clamps the component.

[0026] The first groove 211 is provided on the fixing block 21. The thickness of the fixing block 21 (which is defined in the same direction as the thickness of the fixing plate 23) is 16-20 mm, preferably 18.8 mm, and the width is 16-20 mm, preferably 18 mm. This data range allows the contact area between the first groove 211 and one end of the component to be reasonable so as to achieve effective clamping.

[0027] The extension member 22 has an inverted L-shaped structure. The second groove 221 is located at the end of the extension member 22 away from the fixing plate 23. In this embodiment, the width of the support 2 (which can be understood as the farthest distance from the end of the extension member 22 away from the fixing plate 23 to the fixing plate 23) is 90-105mm, preferably 97mm, and the extension length of the extension member 22 away from the fixing plate 23 is 65-70mm, preferably 67mm. Within this range, the width of the support 2 and the extension length of the extension member 22 are compatible with the length of the bracket 2 13 and the snap-fit ​​fixing position on the bracket 2 13, ensuring that the hinge part 11 remains in a rigid straight state when fixed. The groove width of the second groove 221 is 8-13mm, slightly larger than the width of the bracket 2 13, ensuring smooth locking and removal operations.

[0028] The positional arrangement of the fixing block 21 and the extension 22 satisfies the requirement that the first groove 211 and the second groove 221 can be inserted into the rotatable component and that the rotation angle is satisfied when the rotatable component is fixed.

[0029] In this embodiment, based on the elongated structure of bracket 12 and bracket 23, the first groove 211 and the second groove 221 are designed as U-shaped grooves with a 90-degree bend at the bottom transition section. Furthermore, the length of the groove side of the first groove 211 away from the support 2 is shorter than the length of the other groove side. Simultaneously, the groove side of the first groove 211 away from the support 2 has a downward tilt angle of 11-13°, preferably 12°. This design, after repeated verification, ensures that the data range is sufficient for convenient and quick installation and disassembly of the brackets. Since the bracket mounting surface is relatively large, if both sides of the first groove 211 were long, it would be inconvenient for installation and disassembly operations.

[0030] In this embodiment, since the hinge portion 11 of the dual-section speed-regulating bracket 1 is in a rigid straight line state, its bracket 12 and bracket 23 are in a parallel state. Therefore, the extension directions of the designed first groove 211 and second groove 221 are also parallel (the extension directions of the two grooves can be mapped onto a plane to determine parallelism or an angle). In other embodiments, if it is necessary to control the rotatable component to be fixed at a certain angle after rotation, the angle formed by the extension directions of the second groove 221 and the first groove 211 can be designed to adapt to this special angle.

[0031] In this embodiment, since fixing requires inserting the second bracket 13 of the double-section speed-regulating bracket 1 into the second groove 221, and then rotating the first bracket 12 clockwise to insert it into the first groove 211, the opening of the first groove 211 is set to face horizontally forward, and the opening of the second groove 221 is set to face vertically downward, to adapt to the clockwise rotation direction. In other embodiments, if it is necessary to rotate the first bracket 12 counterclockwise, the opening of the second groove 221 can be set to face vertically downward, and the opening of the first groove 211 can be set to face horizontally backward, to adapt to the counterclockwise rotation direction; similarly, the opening of the second groove 221 can also be set to face vertically upward, and the opening of the first groove 211 can be set to face horizontally forward or backward, to adapt to a suitable rotation direction, specifically determined according to the structure and rotation direction of the rotatable component.

[0032] In this embodiment, the main body has a movable operating structure to drive the head 6 to move up and down. This is achieved through the following structure: the main body includes a connecting rod 4, and a handle 3 and a moving rod 5 connected by the connecting rod 4. When the handle 3 is pulled upwards (e.g., Figure 2 (arrow in the opposite direction), which drives the moving rod 5 upward through the action of the connecting rod 4, and when the handle 3 is pulled downward (as shown by the arrow), the moving rod 5 moves upward through the action of the connecting rod 4. Figure 2 (In the direction of the arrow), the moving rod 5 moves downwards via the action of the connecting rod 4. When the handle 3 is turned upwards to the desired position, the fixing device moves along... Figure 2 The vertical height is 140-155mm, preferably 147.5mm, to ensure that the overall size of the fixing device matches the components, the size is reasonable, and it is easy to operate.

[0033] In this embodiment, the head 6 is threaded to the bottom of the main body, and the spacing is adjusted by adjusting the threaded connection; furthermore, the head 6 is threaded to the bottom of the moving rod 5. The threaded connection not only directly achieves adjustable spacing but also enables detachment, resulting in a simple structure with multiple benefits.

[0034] Furthermore, a support plate 7 is provided on the second side of the support 2, and a guide cylinder 71 is provided on the support plate 7 along the moving path of the moving rod 5. The length of the guide cylinder 71 is less than the length of the moving rod 5. The moving rod 5 passes through the guide cylinder 71, is connected to the connecting rod 4 above the guide cylinder 71, and is connected to the head 6 below the guide cylinder 71. The guide cylinder 71 guides the moving rod 5 when it moves, thereby improving the directional stability of the moving rod 5.

[0035] In this embodiment, the head 6 is a conical head, which forms an inclined structure that gradually narrows downwards in the vertical direction through its conical surface. The maximum diameter of the conical head cross-section is 11-13 mm, preferably 12 mm, and the overall structure is reasonable, ensuring appropriate clamping strength.

[0036] like Figure 3 As shown, the main steps of using the fixing device provided in this embodiment to fix the double-section adjusting bracket are as follows:

[0037] Handle 3 is in the fully open upward position. By adjusting the threaded connection between the cone head and the moving rod 5, the cone head is adjusted to a suitable position, ensuring that after handle 3 is in the fully open upward position, the bottom end of the cone head does not exceed the first groove 211 and does not interfere with the process of bracket 12 engaging with the first groove 211 of support 2. The adjustment of the threaded connection between the cone head and the moving rod 5 ultimately adjusts the clamping force between the cone head and bracket 12. The cone head is adjusted and verified repeatedly at the beginning, and then used extensively. The verification method is to use a fixed device to clamp the bracket. When the clamping force at a certain position is suitable, it indicates that the suitable position of the cone head has been confirmed and verified. Generally, the cone head is no longer adjusted after handle 3 is lowered to the dead center position.

[0038] The second bracket 13 of the double-section adjustment bracket is locked in the second groove 221 of the support 2, the first bracket 12 is rotated around the hinge part 11, and the first bracket 12 is locked in the first groove 211 of the support 2.

[0039] Push the handle 3 downwards, and under the action of the connecting rod 4, the moving rod 5 and the head 6 (conical head) will move downwards in sequence;

[0040] As the conical head moves downward, its conical surface contacts the bracket 12 until the handle 3 enters the dead position and locks the bracket.

[0041] By using the fixing device of this solution and through the above operation steps, the first bracket 12 and the second bracket 13 of the double-section speed-regulating bracket 1 can be rotated around their hinge part 11 to a straight and rigid fixed state, thereby reducing the control factors of the employee's hands directly affecting the rigid fixation of the bracket.

[0042] Of course, in other embodiments, by changing the angle difference between the first groove 211 and the second groove 221 relative to the support, the bracket 12 and the bracket 23 can be rotated around their hinge portion 11 at any angle, i.e., non-linear rigid fixation.

[0043] The fixing device for rotatable components provided in this embodiment can help operators quickly and accurately control the rigid fixation of the component after rotation, reduce control factors in the operation process, reduce the difficulty of operation, and indirectly improve the pass rate. The device has a simple structure and is easy to operate. The design of detachable components makes disassembly and maintenance convenient, and damaged parts can be replaced independently, reducing costs.

Typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
