Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically relating to a processing and fastening device for a dust cover for a rear pillar of an automobile. Background Technology

[0002] The rear strut dust cover is an important component of the suspension system, specifically designed to protect the rear suspension components from external dust, dirt, impurities, and moisture. It is typically fitted directly onto the shock absorber or suspension component, ensuring a tight fit with the strut and secured with circlips, clips, or tension straps. This prevents these contaminants from entering the shock absorber or other suspension components, thus extending their lifespan and maintaining the proper functioning of the suspension system.

[0003] Common automotive rear pillar dust covers are typically produced by injection molding or one-piece rubber molding. After molding, workers need to perform finishing, drilling, or accessory installation. In subsequent processing, the dust cover needs to be secured to prevent movement or deformation. For example, after demolding, the injection molded part still has residual heat and is relatively soft, making it susceptible to deformation under external pressure. Therefore, we need to provide a fastening device to secure the dust cover during processing, ensuring it maintains a stable shape and avoiding unnecessary processing errors caused by deformation. Utility Model Content

[0004] The purpose of this utility model is to provide a processing and fastening device for a dust cover on a car rear pillar, which can fasten the outer support of the dust cover to avoid squeezing and deformation of the dust cover, thereby ensuring the fastening of the dust cover and ensuring the final specifications of the product.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A machining and fastening device for a car rear pillar dust cover includes a turntable with an external support mechanism on one side. The external support mechanism includes a cylinder, a sleeve, a lead screw, a connecting rod, external support members, limiting grooves, and guide blocks. The cylinder is fixedly connected to one side of the turntable. The sleeve is fitted onto the surface of the lead screw, which is threaded into the inside of the cylinder. One end of the lead screw is rotatably connected to the inner wall of the sleeve, and the other end of the lead screw extends to the other side of the turntable. One end of each connecting rod is connected to the surface of the sleeve via an ear plate. Three external support members are connected to the other end of the connecting rod via ear plates. The external support members are located on one side of the turntable. Three limiting grooves are formed on one side of the turntable. Three guide blocks are fixedly connected to one side of each of the three external support members and slidably connected to the inside of each of the three limiting grooves.

[0007] Preferably, an auxiliary sleeve is fitted on the surface of the turntable, the turntable is rotatably connected to the inside of the auxiliary sleeve, and a base is fixedly connected to the bottom of the auxiliary sleeve.

[0008] Preferably, a limiting strip is fixedly connected to the inner wall of the sleeve, and a sliding groove is formed on the surface of the cylinder, with the limiting strip slidably connected inside the sliding groove.

[0009] Preferably, all three outer support members are arc-shaped, and anti-slip grooves are formed on the outer surface of all three outer support members.

[0010] Preferably, each of the three guide blocks is fitted with a limiting ring, which is located on one side of the turntable.

[0011] Preferably, one end of the lead screw is fixedly connected to an adjustment knob, and the adjustment knob is circular.

[0012] Preferably, there are several connecting rods, which are evenly connected to the inner side of the three outer support members.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, when the dust cover needs to be processed and fastened, the dust cover can be directly placed on the outer surface of the outer support member. Then, the lead screw is rotated away from the turntable. As the lead screw rotates inside the cylinder, it moves away from the turntable. When the lead screw moves away from the turntable, it drives the sleeve to move towards the turntable on the surface of the cylinder. After the sleeve moves towards the turntable, it pushes the outer support member outward through the connecting rod. When the outer support member moves outward, it drives the guide block to move smoothly inside the limiting groove. This allows the outer support member to move smoothly outward at the same time. Under the outward support of the outer support member, the dust cover is fastened and supported on the surface of the outer support member. This ensures that the dust cover receives a uniform and precise external support force, thereby effectively preventing deformation and maintaining the shape and processing accuracy of the dust cover.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-4 As shown, a machining and fastening device for a car rear pillar dust cover includes a turntable 1, with an external support mechanism on one side of the turntable 1. The external support mechanism includes a cylinder 201, a sleeve 202, a lead screw 203, a connecting rod 207, external support members 204, a limiting groove 205, and a guide block 206. The cylinder 201 is fixedly connected to one side of the turntable 1. The sleeve 202 is fitted onto the surface of the lead screw 203, which is threaded into the interior of the cylinder 201. One end of the lead screw 203 is rotatably connected to the inner wall of the sleeve 202, and the other end of the lead screw 203 extends to the other side of the turntable 1. One end of each connecting rod 207 is connected to the surface of the sleeve 202 via an ear plate. Three external support members 204 are connected to the other end of the connecting rod 207 via ear plates. The external support members 204 are located on one side of the turntable 1. Each limiting groove 205 is opened on one side of the turntable 1. Three guide blocks 206 are fixedly connected to one side of the three external support members 204. The three guide blocks 206 are slidably connected to the inside of the three limiting grooves 205. With the cooperation of the external support mechanism, when the dust cover is tightened, the screw 203 can be rotated to move the sleeve 202. The movement of the sleeve 202 can drive and squeeze the connecting rod 207 to support it. At the same time, the connecting rod 207 drives the external support member 204 to move outward smoothly under the limitation of the limiting grooves 205 and the guide blocks 206. Under the external support force of the external support member 204, the dust cover is evenly tightened, preventing the dust cover from moving during the processing and ensuring the smooth progress of the processing.

[0023] like Figures 1-3As shown, an auxiliary sleeve 301 is fitted on the surface of the turntable 1. The turntable 1 is rotatably connected to the inside of the auxiliary sleeve 301. A base 302 is fixedly connected to the bottom of the auxiliary sleeve 301. When the dust cover is being fastened, if the angle of the dust cover needs to be adjusted, the turntable 1 can be directly rotated inside the auxiliary sleeve 301 under the support and limitation of the base 302 and the auxiliary sleeve 301. When the turntable 1 rotates, it can drive the fastened dust cover to rotate and adjust, which simplifies the complexity of traditional adjustment and saves processing time and effort.

[0024] like Figure 4 As shown, a limiting strip 401 is fixedly connected to the inner wall of the sleeve 202. A sliding groove 402 is provided on the surface of the cylinder 201. The limiting strip 401 is slidably connected to the inside of the sliding groove 402. When the sleeve 202 slides on the surface of the cylinder 201, the sleeve 202 can drive the limiting strip 401 to slide parallel inside the sliding groove 402, preventing the sleeve 202 from rotating on the surface of the cylinder 201 when it moves. This ensures that the sleeve 202 always moves along the parallel direction of the sliding groove 402, avoiding unnecessary rotation of the sleeve 202 that would affect the normal operation of the external support mechanism and prevent the dust cover from being stably tightened.

[0025] like Figure 1 and Figure 4 As shown, all three outer support members 204 are arc-shaped, and anti-slip grooves 5 are provided on the outer surface of each of the three outer support members 204. The arc-shaped outer support members 204 can better distribute the applied force through their shape, and the arc structure can better adapt to the curve of the force-bearing surface of the inner wall of the dust cover, thereby providing more stable support and fastening of the dust cover. This avoids the uneven force distribution that may be caused by traditional planar support. At the same time, the design of the anti-slip grooves 5 helps to increase the friction between the contact surface with the dust cover, reduce the possibility of sliding or slipping, and provide a stronger anti-slip effect, which can effectively improve the safety and stability of fastening the dust cover.

[0026] like Figure 3 As shown, each of the three guide blocks 206 is fitted with a limiting ring 6. The limiting ring 6 is located on one side of the turntable 1. When the outer support 204 drives the guide block 206 to slide inside the sliding groove 402, in order to prevent the guide block 206 from deviating from the sliding groove 402, the limiting ring 6 can stably limit the guide block 206 inside the sliding groove 402, ensuring that it always stays inside the sliding groove 402 and avoiding unnecessary offset or positional error.

[0027] like Figure 3 and Figure 4As shown, an adjustment knob 7 is fixedly connected to one end of the lead screw 203. The adjustment knob 7 is circular. The design of the circular adjustment knob 7 can provide a uniform rotational torque, making the adjustment of the lead screw 203 more stable and easier to control. In addition, the circular adjustment knob 7 can greatly reduce hand fatigue and improve the comfort of operation.

[0028] like Figure 4 As shown, there are several connecting rods 207, which are evenly connected to the inner side of the three outer support members 204. The even distribution of the connecting rods 207 on the inner side of the outer support members 204 helps to evenly distribute the external force, making the whole structure more stable and avoiding deformation or damage caused by uneven local force, thereby improving the compressive strength and stability of the outer support mechanism.

[0029] The working principle of this utility model is as follows: When it is necessary to process and fasten the dust cover, the dust cover can be directly placed on the outer surface of the outer support 204. Then, the lead screw 203 is rotated away from the turntable 1. While the lead screw 203 rotates inside the cylinder 201, it will also move away from the turntable 1. When the lead screw 203 moves away from the turntable 1, it can drive the sleeve 202 to move towards the turntable 1 on the surface of the cylinder 201. After the sleeve 202 moves towards the turntable 1, it will push the outer support 204 outward through the connecting rod 207. When the outer support 204 moves outward, it can drive the guide block 206 to move smoothly inside the limiting groove 205. Thus, the outer support 204 can move outward smoothly at the same time. Under the outward support of the outer support 204, the dust cover is fastened and supported on the surface of the outer support 204. This ensures that the dust cover receives a uniform and precise external support force, thereby effectively preventing deformation and maintaining the shape and processing accuracy of the dust cover.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
