DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The first embodiment of the present application is as follows:

[0021] Please refer to Figure 1 - Figure 2 , wherein, Figure 1It is a schematic diagram of the overall structure of the first embodiment of the present utility model. Figure 2 It is a sectional view of the overall structure of the first embodiment of the present utility model.

[0022] The present utility model provides a fixing mechanism for processing an automobile door frame assembly, which includes a bottom plate 101 and a plurality of fixing components 102. The plurality of fixing components 102 are respectively located on the side of the bottom plate 101. The fixing component 102 includes a first threaded screw rod 103, a slider 104, a support seat 105, a guide rail 106, a moving block 107, a second threaded screw rod 108, a pressing plate 109 and a knob 110. Through the foregoing solution, the automobile door frame assembly can be fixed to prevent the automobile door frame assembly from moving during the processing.

[0023] For this specific embodiment, the bottom plate 101 is used to support the automobile door frame assembly.

[0024] Among them, the first threaded lead screw 103 is rotatably connected to the bottom plate 101 and is located on the side of the bottom plate 101; the slider 104 is slidably connected to the bottom plate 101, is threadedly connected to the first threaded lead screw 103, and is located on the side of the first threaded lead screw 103; the support base 105 is fixedly connected to the slider 104 and is located on the top of the slider 104; the guide rail 106 is fixedly connected to the support base 105 and is located on the top of the support base 105; the moving block 107 is slidably connected to the guide rail 106 and is located inside the guide rail 106; the second threaded lead screw 108 is rotatably connected to the guide rail 106, is threadedly connected to the moving block 107, and is located on the side of the guide rail 106; the pressing plate 109 is fixedly connected to the moving block 107 and is located on the side of the moving block 107. A chute adapted to the slider 104 is provided on the bottom plate 101 for the slider 104 to slide and at the same time to restrict the rotation of the slider 104; when machining the automobile door frame assembly is required, the automobile door frame assembly is placed on the bottom plate 101, and the worker rotates the first threaded lead screw 103 forward. The rotation of the first threaded lead screw 103 causes the slider 104 to slide along the bottom plate 101. The slider 104 drives the support base 105 and the guide rail 106 to move and approach the automobile door frame assembly until the side of the guide rail 106 contacts the automobile door frame assembly, and the horizontal position of the automobile door frame assembly is fixed by means of a plurality of the guide rails 106; subsequently, the worker rotates the second threaded lead screw 108 forward. The forward rotation of the second threaded lead screw 108 causes the moving block 107 to move downward along the guide rail 106. The moving block 107 drives the pressing plate 109 to move downward, so that the pressing plate 109 contacts the upper surface of the automobile door frame assembly, and the longitudinal position of the automobile door frame assembly is limited and fixed by means of the pressing plate 109. Since the first threaded lead screw 103 and the bottom plate 101 are connected by a threaded method, and at the same time the second threaded lead screw 108 and the guide rail 106 are also connected by a threaded method, and the thread has self-locking property, the guide rail 106 and the pressing plate 109 will not move when pushed, so as to ensure a firm fixing effect on the automobile door frame assembly and prevent the automobile door frame assembly from moving during the machining process.

[0025] Secondly, the knob 110 is fixedly connected to the second threaded lead screw 108 and is located at the bottom of the second threaded lead screw 108. The user can hold the knob 110 to facilitate the rotation of the second threaded lead screw 108.

[0026] When using the present utility model to process an automobile door frame assembly, place the automobile door frame assembly on the bottom plate 101. The worker rotates the first threaded screw rod 103 in the forward direction. The rotation of the first threaded screw rod 103 causes the slider 104 to slide along the bottom plate 101. The slider 104 drives the support seat 105 and the guide rail 106 to move and approach the automobile door frame assembly until the side of the guide rail 106 contacts the automobile door frame assembly, and the horizontal position of the automobile door frame assembly is fixed by using a plurality of the guide rails 106. Subsequently, the worker rotates the second threaded screw rod 108 in the forward direction. The forward rotation of the second threaded screw rod 108 causes the moving block 107 to move downward along the guide rail 106. The moving block 107 drives the pressing plate 109 to move downward, so that the pressing plate 109 contacts the upper surface of the automobile door frame assembly, and the longitudinal position of the automobile door frame assembly is limited and fixed by using the pressing plate 109. Since the first threaded screw rod 103 and the bottom plate 101 are connected by a threaded manner, and at the same time the second threaded screw rod 108 and the guide rail 106 are also connected by a threaded manner, and the thread has self-locking property, so when the guide rail 106 and the pressing plate 109 are pushed, they will not move, thus ensuring a firm fixing effect on the automobile door frame assembly and preventing the automobile door frame assembly from moving during the processing.

[0027] The second embodiment of the present application is as follows:

[0028] On the basis of the first embodiment, please refer to Figure 3 - Figure 4 , wherein, Figure 3 is the overall structural schematic diagram of the second embodiment of the present utility model, Figure 4 is the overall sectional view of the second embodiment of the present utility model.

[0029] A fixing mechanism for processing an automobile door frame assembly provided by the present utility model, the fixing component 102 further includes a locking portion 201; the locking portion 201 includes a sliding rod 202, a gear ring 203, a fixed seat 204, an anti-detachment block 205, a spring 206 and a grip 207.

[0030] For this specific embodiment, the locking portion 201 is arranged on the side of the first threaded screw rod 103. The first threaded screw rod 103 can be fixed by the locking portion 201 to prevent the first threaded screw rod 103 from rotating when being accidentally touched.

[0031] Among them, the sliding rod 202 is slidably connected to the first threaded lead screw 103 and is located inside the first threaded lead screw 103; the gear ring 203 is fixedly connected to the sliding rod 202 and is located on the side of the sliding rod 202; the fixed seat 204 is fixedly connected to the bottom plate 101 and is located on the side of the bottom plate 101. A plurality of teeth are provided on the outside of the gear ring 203, and a tooth groove adapted to the gear ring 203 is provided on the inside of the fixed seat 204. After the position of the automobile door frame assembly is fixed, the worker slides the sliding rod 202 to slide the gear ring 203 into the fixed seat 204. The fixed seat 204 will restrict the rotation of the gear ring 203. Therefore, the sliding rod 202 and the first threaded lead screw 103 cannot rotate, so as to prevent the first threaded lead screw 103 from rotating when being accidentally touched, and avoid the position of the slider 104 from moving due to the rotation of the first threaded lead screw 103, thereby improving the fixing effect on the automobile door frame assembly.

[0032] Secondly, the anti - detachment block 205 is fixedly connected to the sliding rod 202, is slidably connected to the first threaded lead screw 103, and is located inside the first threaded lead screw 103; the spring 206 is fixedly connected to the anti - detachment block 205 and is fixedly connected to the first threaded lead screw 103, and is located between the anti - detachment block 205 and the first threaded lead screw 103. When it is necessary to rotate the first threaded lead screw 103 to adjust the position of the slider 104, the worker pulls the sliding rod 202 to move the gear ring 203 out of the fixed seat 204. The sliding rod 202 drives the anti - detachment block 205 to move and stretches the spring 206. The anti - detachment block 205 is used to prevent the sliding rod 202 from disengaging from the first threaded lead screw 103. After the position of the slider 104 is fixed, the sliding rod 202 is released, and the gear ring 203 slides into the fixed seat 204 under the action of the spring 206. By providing the spring 206, it can prevent the gear ring 203 from disengaging from the fixed seat 204 when the bottom plate 101 vibrates.

[0033] In addition, the handle 207 is fixedly connected to the sliding rod 202 and is located at one end of the sliding rod 202 away from the anti - detachment block 205. The worker can easily control the sliding rod 202 by holding the handle 207.

[0034] When using the present utility model, when it is necessary to rotate the first threaded lead screw 103 to adjust the position of the slider 104, the staff pulls the sliding rod 202 to move the toothed ring 203 out of the fixed seat 204. The sliding rod 202 drives the anti - detachment block 205 to move, stretching the spring 206. The anti - detachment block 205 is used to prevent the sliding rod 202 from detaching from the first threaded lead screw 103. After the position of the slider 104 is fixed, the sliding rod 202 is released. The toothed ring 203 slides into the fixed seat 204 under the action of the spring 206. The fixed seat 204 restricts the rotation of the toothed ring 203. Therefore, the sliding rod 202 and the first threaded lead screw 103 cannot rotate, thereby preventing the first threaded lead screw 103 from rotating when being accidentally touched, avoiding the movement of the slider 104 position caused by the rotation of the first threaded lead screw 103, and further improving the fixing effect on the automobile door frame assembly. Through the arranged spring 206, it can prevent the toothed ring 203 from detaching from the fixed seat 204 when the bottom plate 101 vibrates.

[0035] The above - disclosed are only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand all or part of the processes of implementing the above - mentioned embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
