[0002] A sunroof on a car not only enhances its aesthetic appeal and class but also provides excellent ventilation, cooling, and defogging functions. Generally, the process begins by assembling the sunroof rails and other components of the sunroof glass to form a frame. The mounting edges of the rails are then secured to the car's roof, thus fixing the sunroof to the roof as a whole.

[0030] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0031] Example 1:
[0032] Please see Figures 1 to 4 As shown, this embodiment provides a fixture for an automotive sunroof guide rail, including: a processing table 1, and a Y-direction limiting component 2 and an X-direction limiting component 3, both mounted on the processing table 1, suitable for limiting the guide rail from its upper and lower end faces and suitable for limiting the guide rail from its left and right sides. The X-direction limiting component 3 and the Y-direction limiting component 2 work together in two mutually perpendicular directions to achieve rapid and precise positioning and clamping of the automotive sunroof guide rail.
[0033] Specifically, firstly, the Y-direction limiting assembly 2 includes a support block 21 for supporting the sunroof guide rail from the bottom, and a pressing assembly 22 adapted to press against the sunroof guide rail from the top. The support block 21 is fixed on the processing table 1, and the pressing assembly 22, in accordance with the accompanying drawings, in one optional case, includes at least two pressing members 221 spaced apart along the length of the sunroof guide rail, and a first actuator 222 for moving the pressing members 221 to switch their contact and disengagement states with the sunroof guide rail.
[0034] More specifically, in this embodiment, the pressing member 221 includes a rotating arm 2211 and a pressing head 2212 detachably disposed at one end of the rotating arm 2211 for pressing against the sunroof guide rail. This detachable fit between the pressing head 2212 and the rotating arm 2211 allows for replacement of the pressing head 2212 after wear from prolonged use. In an optional implementation, an elastic material, such as but not limited to rubber, can be fitted onto the pressing head 2212. The use of the sleeve can, on the one hand, prevent wear on the outer surface of the sunroof guide rail due to the contact, and on the other hand, utilize the elastic properties of the sleeve to improve the reliability of contact with the outer surface of the sunroof guide rail when the rotating arm 2211 drives the pressing head 2212 to rotate to the outer surface of the sunroof guide rail, reducing hard friction between the pressing head 2212 and the outer surface of the sunroof guide rail.
[0035] Based on the above structure, and referring to the accompanying drawings, in one optional implementation, the first actuator 222 employs a rotary cylinder. This rotary cylinder can directly rotate the pressing component 221 to complete the engagement and disengagement of the sunroof guide rail, simplifying the operation steps, improving the efficiency of batch processing, reducing the failure rate, and decreasing processing energy consumption. In other words, for the Y-axis limiting of the sunroof guide rail, the Y-axis limiting component 2 only needs a single rotational movement to switch between limiting and releasing the sunroof guide rail, making the process convenient and efficient.
[0036] Based on the above, in an optional implementation, considering that the height at which different specifications of automotive sunroof guide rails are placed on the support block 21 may vary during actual processing, the following design can be made to improve the applicability of the fixture tooling for automotive sunroof guide rails in this embodiment:
[0037] At the bottom of the first driver 222, there is a lifting adjustment structure 223 for driving it to move up and down; the lifting adjustment structure 223 can be a manually adjustable lifting seat (fixed seat 3111 and movable seat that can be raised and lowered with the fixed seat 3111, and a locking element such as, but not limited to, screws is provided between the two, the first driver 222 is fixed on the movable seat, and the overall lifting seat height is different by adjusting the matching height between the movable seat and the fixed seat 3111, thereby adjusting the usage height of the first driver 222 relative to the car sunroof guide rail).
[0038] Next, it should be noted that the X-direction limiting component 3 includes a lateral positioning group 31 adapted to limit the left side of the car sunroof guide rail, and a lateral limiting group 32 adapted to limit the right side of the car sunroof guide rail.
[0039] In this regard, the lateral positioning assembly 31 includes at least two positioning pins 311 arranged at intervals along the length of the sunroof guide rail on the left side of the sunroof guide rail. The positioning pin 311 includes a fixing seat 3111 and a pin 3112 detachably mounted on the positioning seat. If the pin 3112 wears out after long-term use, the pin 3112 can be replaced.
[0040] Accordingly, it should be noted that, in one optional implementation, each pin 3112 is adapted to be inserted into the positioning hole of the sunroof guide rail; in another optional implementation, each pin 3112 is adapted to be abutted against the left side of the sunroof guide rail, in which case, for the sunroof guide rail mounted on the support block 21, only one side end face needs to be abutted against the pin 3112.
[0041] Furthermore, the lateral limiting assembly 32 includes at least two limiting heads 321 spaced apart along the length of the sunroof guide rail, and a second actuator 322 for driving the limiting heads 321 to perform linear motion to switch their contact and disengagement states with the sunroof guide rail. Here, the limiting heads 321 and the positioning pins 311 are located on two different sides of the sunroof guide rail. For the overall X-axis limiting assembly 3, corresponding to the two different sides of the sunroof guide rail, one side requires the second actuator 322, while the other side has a relatively fixed positioning pin 311. This design simplifies both the structure and the usage process.
[0042] Based on the above, and referring to the accompanying drawings, in one optional embodiment, the second actuator 322 is a linear cylinder; the limiting head 321 is connected to the second actuator 322 via a guide post 323, and the limiting head 321 and the guide post 323 are detachably fitted. If the limiting head 321 wears out due to long-term use, it can be replaced. It is understood that, in one optional embodiment, a sleeve made of an elastic material, such as, but not limited to, rubber, can be fitted onto the limiting head 321. The use of the sleeve can, on the one hand, prevent wear on the outer surface of the sunroof guide rail due to the contact fit; on the other hand, the elasticity of the sleeve can reduce the hard friction between the limiting head 321 and the outer surface of the sunroof guide rail when the guide post 323 drives the limiting head 321 to move linearly to the outer surface of the sunroof guide rail.
[0043] Based on the above structure, it should be noted that the lateral limiting assembly 32 also includes a support seat 324 mounted on the processing table 1 for sliding engagement with the guide post 323. The engagement between the guide post 323 and the support seat 324 improves the reliability of the linear movement of the limiting head 321, while enhancing the lateral clamping effect of the limiting head 321 on the automotive sunroof guide rail.
[0044] Furthermore, it is necessary to note that, in actual processing, the height at which different specifications of car sunroof guide rails are placed on the support block 21 may vary. For the lateral limiting group 32 and lateral positioning group 31 of this embodiment, even without a lifting structure, they can be used with a certain range of car sunroof guide rails. Therefore, both the lateral positioning group 31 and the lateral limiting group 32 only abut against the side of the car sunroof guide rail, while the contact area between the lateral positioning group 31 and the lateral limiting group 32 and the car sunroof guide rail itself can be within a certain range. The adjustable floating within the range can meet the usage requirements. When the height of the car sunroof guide rail on the support block 21 is relatively large, the contact area between the lateral limiting group 32 and the lateral positioning group 31 and the car sunroof guide rail can be relatively small. When the height of the car sunroof guide rail on the support block 21 is relatively small, the contact area between the lateral limiting group 32 and the lateral positioning group 31 and the car sunroof guide rail can be relatively large. Therefore, the lateral limiting group 32 and the lateral positioning group 31 in this embodiment can be used for car sunroof guide rails of different specifications within a certain range.
[0045] In summary, the fixture used in this embodiment for the automotive sunroof guide rail simplifies the fixture structure and saves processing costs by setting a limiting head 321, a guide post 323, and a linear cylinder on the right side of the automotive sunroof guide rail, and setting a positioning pin 311 on the left side of the automotive sunroof guide rail to replace the linear cylinder. The rotary cylinder, rotating arm 2211, and pressing head 2212 limit the automotive sunroof guide rail in the Y direction. The rotary cylinder drives the rotating arm 2211 and the pressing head 2212 to rotate directly, achieving the contact and disengagement of the pressing head 2212 with the automotive sunroof guide rail. The structure is simple, simplifying its use and operation, accelerating the production process, reducing equipment operating time and manpower input, saving energy, reducing processing failure rate, and improving the efficiency of batch processing.
