Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a clamp for processing automotive sensor brackets. Background Technology

[0002] A fixture is a device used in the machining and manufacturing process to fix the workpiece to be processed, so that it occupies the correct position for construction or inspection.

[0003] Automotive sensor brackets are key components of the vehicle chassis suspension, used to position and mount sensors. Sensor brackets are typically small in size and require high dimensional accuracy. One type is shown in the attached figure. Figure 8 The sensor bracket 100 shown includes an upper bracket 101 and a lower bracket 102. The outer diameter of the upper bracket 101 is larger than the outer diameter of the lower bracket 102. A through hole 103 is provided in the center of the sensor bracket 100. An inclined annular protrusion 104 is provided between the upper bracket 101 and the lower bracket 102. The annular protrusion 104 is provided with an upwardly bent portion 1041. An anti-rotation protrusion 1011 is provided on the outer side wall of the upper bracket 101. A chamfered surface is provided at one end of the through hole 103 of the upper bracket 101. During the processing of the aforementioned sensor bracket 100, it is necessary to mill the end face 1012 of the upper part 101 of the bracket and to perform internal thread processing on the inner wall 1031 of the through hole 103 of the upper part 101 of the bracket. Since the shape of the automotive sensor bracket 100 is irregular, traditional fixtures have difficulty in positioning and fixing such an irregularly shaped automotive sensor bracket 100, resulting in insufficient milling accuracy and thread accuracy, which affects the installation of the automotive sensor bracket 100.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional fixtures in the prior art are difficult to position and fix irregularly shaped car sensor brackets, resulting in insufficient milling and thread accuracy, which affects the installation of car sensors. Therefore, this invention proposes a fixture for processing car sensor brackets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixture for processing an automotive sensor bracket includes a positioning seat and a clamping sleeve that open and close along the axial direction. The positioning seat and the clamping sleeve cooperate to form a receiving cavity for mounting the sensor bracket. The receiving cavity is provided with an annular groove that cooperates with an annular protrusion. The annular groove includes a bending groove that cooperates with a bending portion. The clamping sleeve is provided with a positioning hole for the upper part of the sensor bracket to extend out. The clamping sleeve is provided with a notch groove that cooperates with the anti-rotation protrusion of the sensor bracket for limiting.

[0008] Furthermore, the clamping sleeve includes a sleeve and a clamping cap, the positioning hole and the notch are both provided on the clamping cap, and an anti-rotation mechanism is provided between the sleeve and the clamping cap to achieve an anti-rotation fit between the sleeve and the clamping cap.

[0009] Furthermore, the anti-rotation mechanism includes an anti-rotation block, an anti-rotation port disposed on the pressure cover, and a first anti-rotation groove disposed on the inner side wall of the sleeve. The side of the anti-rotation block near the sleeve is embedded in the first anti-rotation groove, and the end of the anti-rotation block extends into the anti-rotation port.

[0010] Furthermore, the outer wall of the positioning seat is provided with a second anti-rotation groove opposite to the first anti-rotation groove, and the side of the anti-rotation block closest to the positioning seat is embedded in the second anti-rotation groove.

[0011] Furthermore, the anti-rotation block is fixedly connected to the first anti-rotation groove, and the anti-rotation block is slidably connected to the second anti-rotation groove.

[0012] Furthermore, the end of the anti-rotation block is provided with a stepped portion, which is matched with the anti-rotation port of the pressure cover to limit the anti-rotation block from coming out of the anti-rotation port of the pressure cover.

[0013] Furthermore, the positioning seat and the clamping sleeve have a first working state and a second working state. When the positioning seat and the clamping sleeve are in the first working state, the positioning seat and the clamping sleeve are in a separate engagement, and the sensor bracket can be taken out or installed at this time. When the positioning seat and the clamping sleeve are in the second working state, the positioning seat and the clamping sleeve are in a press-fit engagement, and the sensor bracket is pressed into the receiving cavity at this time.

[0014] Furthermore, when the positioning seat and the clamping sleeve are in the second working state, a first gap and a second gap are formed between the positioning seat and the clamping sleeve.

[0015] Furthermore, the positioning seat is provided with a clearance groove that corresponds to and engages with the through hole of the sensor bracket.

[0016] The beneficial effects of this utility model after adopting the above structure are as follows: The fixture for processing automotive sensor brackets according to this utility model includes a positioning seat and a clamping sleeve that open and close along the axial direction. The positioning seat and the clamping sleeve cooperate to form a receiving cavity for installing the sensor bracket. The receiving cavity is provided with an annular groove that cooperates with an annular protrusion. The annular groove includes a bending groove that cooperates with a bending portion. The clamping sleeve is provided with a positioning hole for the upper part of the sensor bracket to extend out. The clamping sleeve is provided with a notch groove that cooperates with the anti-rotation protrusion of the sensor bracket for limiting. This utility model uses a positioning seat and a clamping sleeve to position the sensor bracket as a whole, accurately positioning and reliably fixing the sensor bracket. This makes the sensor bracket less prone to loosening during processing, ensuring the processing accuracy of the sensor bracket from the source, and greatly improving the quality and stability of the sensor bracket.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] In the description of this utility model, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] In this utility model, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0034] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 8 As shown, a fixture for processing an automotive sensor bracket includes a positioning seat 1 and a clamping sleeve 2 that open and close along the axial direction. The positioning seat 1 and the clamping sleeve 2 cooperate to form a receiving cavity 3 for mounting a sensor bracket 100. The receiving cavity 3 is provided with an annular groove 31 that cooperates with an annular protrusion 104. The annular groove 31 includes a bending groove 311 that cooperates with a bending portion 1041. The clamping sleeve 2 is provided with a positioning hole 221 for the upper part 101 of the sensor bracket 100 to extend out. The clamping sleeve 2 is provided with a notch 222 that limits the movement of the anti-rotation protrusion 1011 of the sensor bracket 100.

[0036] Based on the above embodiments, the present invention aims to provide a fixture for processing automotive sensor brackets, including a positioning seat 1 and a clamping sleeve 2 that open and close along the axial direction. The positioning seat 1 and the clamping sleeve 2 cooperate to form a receiving cavity 3 for mounting a sensor bracket 100. The receiving cavity 3 is provided with an annular groove 31 that cooperates with an annular protrusion 104. The annular groove 31 includes a bending groove 311 that cooperates with a bending portion 1041. The clamping sleeve 2 is provided with a positioning hole 221 for the upper part 101 of the sensor bracket 100 to extend out. The clamping sleeve 2 is provided with a notch 222 that limits the movement of the anti-rotation protrusion 1011 of the sensor bracket 100. The present invention uses the positioning seat 1 and the clamping sleeve 2 to position the sensor bracket 100 as a whole, accurately positioning and reliably fixing the sensor bracket 100, making it less prone to loosening during processing. This fundamentally ensures the processing accuracy of the sensor bracket 100 and significantly improves the quality and stability of the sensor bracket 100.

[0037] In this embodiment, when the sensor bracket 100 is positioned inside the clamping sleeve 2, the anti-rotation protrusion 1011 on the sensor bracket 100 aligns with the notch 222 of the clamping cover 22. This restricts the rotation of the sensor bracket 100 relative to the clamping sleeve 2 and also provides orientation. When the positioning seat 1 and the clamping sleeve 2 are in the second working state, they are press-fitted together. At this time, the annular groove 31 engages with the annular protrusion 104, achieving accurate positioning and reliable fixation of the sensor bracket 100 as a whole, ensuring processing accuracy. In this embodiment, when the positioning seat 1 and the clamping sleeve 2 are in the second working state, the opening end face 1012 of the upper part 101 of the bracket extends out of the positioning hole 221, facilitating milling of the opening end face 1012 of the upper part 101 of the bracket and internal threading of the inner wall 1031 of the through hole 103.

[0038] In another preferred embodiment of this utility model, the clamping sleeve 2 includes a sleeve 21 and a clamping cover 22. The positioning hole 221 and the notch 222 are both provided on the clamping cover 22. An anti-rotation mechanism 4 is provided between the sleeve 21 and the clamping cover 22 to achieve anti-rotation engagement between the sleeve 21 and the clamping cover 22. The anti-rotation mechanism 4 includes an anti-rotation block 41, an anti-rotation opening 42 provided on the clamping cover 22, and a first anti-rotation groove 43 provided on the inner side wall of the sleeve 21. The side of the anti-rotation block 41 near the sleeve 21 is embedded in the first anti-rotation groove 43, and the end of the anti-rotation block 41 extends into the anti-rotation opening 42. The outer side wall of the positioning seat 1 has a second anti-rotation groove 12 opposite to the first anti-rotation groove 43, and the side of the anti-rotation block 41 near the positioning seat 1 is embedded in the second anti-rotation groove 12. The anti-rotation block 41 is fixedly connected to the first anti-rotation groove 43, and the anti-rotation block 41 is slidably connected to the second anti-rotation groove 12. The end of the anti-rotation block 41 is provided with a stepped portion 411, which is matched with the anti-rotation opening 42 of the pressure cover 22 to limit the anti-rotation block 41 from coming out of the anti-rotation opening 42 of the pressure cover 22.

[0039] In this embodiment, when the positioning seat 1 and the clamping sleeve 2 are in a press-fitting engagement, the anti-rotation block 41 is embedded in the first anti-rotation groove 43 and the second anti-rotation groove 12, thereby achieving an anti-rotation engagement between the clamping sleeve 2 and the positioning seat 1. In this embodiment, the end of the anti-rotation block 41 extends into the anti-rotation opening 42, enabling rapid positioning and anti-rotation engagement between the clamping cover 22 and the sleeve 21, thus ensuring precise alignment between the anti-rotation protrusion 1011 and the notch 222. In this embodiment, the anti-rotation block 41 is fixedly connected to the first anti-rotation groove 43. Specifically, the anti-rotation block 41 is bolted to the first anti-rotation groove 43 of the sleeve 21. When the positioning seat 1 and the clamping sleeve 2 move axially, the anti-rotation block 41 moves with the clamping sleeve 2, thereby achieving a sliding engagement between the anti-rotation block 41 and the second anti-rotation groove 12. In this embodiment, the end of the anti-rotation block 41 is provided with a stepped portion 411, which is matched with the anti-rotation opening 42 of the pressure cover 22 to limit the anti-rotation block 41 from coming out of the anti-rotation opening 42 of the pressure cover 22.

[0040] As another preferred embodiment of this utility model, the positioning seat 1 and the clamping sleeve 2 have a first working state and a second working state. When the positioning seat 1 and the clamping sleeve 2 are in the first working state, they are in a separate engagement, allowing the sensor bracket 100 to be removed or installed. When the positioning seat 1 and the clamping sleeve 2 are in the second working state, they are in a press-fit engagement, pressing the sensor bracket 100 into the receiving cavity 3. When the positioning seat 1 and the clamping sleeve 2 are in the second working state, a first gap 5 and a second gap 6 are formed between them. In this embodiment, as... Figure 5 As shown, when the positioning seat 1 and the clamping sleeve 2 are in the first working state, the positioning seat 1 and the clamping sleeve 2 are in a separate engagement, at which time the sensor bracket 100 can be removed or installed; as Figure 3 As shown, when the positioning seat 1 and the clamping sleeve 2 are in the second working state, the positioning seat 1 and the clamping sleeve 2 are in a press-fitted engagement, at which time the sensor bracket 100 is pressed tightly within the receiving cavity 3. In this embodiment, as... Figure 3 As shown, when the positioning seat 1 and the clamping sleeve 2 are in the second working state, a first gap 5 and a second gap 6 are formed between the positioning seat 1 and the clamping sleeve 2. The setting of the first gap 5 and the second gap 6 facilitates the clamping of the sensor bracket 100 and reduces the precision requirements of the fixture, thereby reducing the processing difficulty of the fixture.

[0041] As another preferred embodiment of this utility model, the positioning seat 1 is provided with a clearance groove 11 that corresponds to and engages with the through hole 103 of the sensor bracket 100. In this embodiment, as... Figure 2 As shown, the clearance groove 11 facilitates the machining of internal threads on the inner wall 1031 of the through hole 103, and avoids interference between the positioning seat 1 and the tool for machining internal threads.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
