Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for brake disc processing, and more specifically, to a hydraulic locking device for quick clamping of brake discs. Background Technology

[0002] Brake discs are a key component of automotive braking systems, and their machining accuracy directly affects the braking performance and driving safety of vehicles. During the production and processing of brake discs, they need to be clamped and fixed multiple times to complete multiple processes such as turning, grinding, and drilling.

[0003] Currently, traditional brake disc clamping devices mostly use mechanical clamps for manual locking. This method has many shortcomings. On the one hand, manual operation is labor-intensive and has low clamping efficiency, making it difficult to meet the needs of mass production. On the other hand, manual operation is prone to insufficient clamping force, which can cause the brake disc to loosen during processing and affect the processing accuracy.

[0004] Furthermore, traditional clamping devices can only clamp brake discs of a fixed model. When encountering brake discs of different sizes, they cannot perform corresponding clamping operations by changing the corresponding clamping components, further reducing production efficiency. Therefore, we propose a hydraulic locking device for quick clamping of brake discs. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic locking device for quick clamping of brake discs, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hydraulic locking device for quick clamping of a brake disc includes a fixed support with a central hole at its center. A support disc is detachably mounted on the fixed support and is inserted into the central hole. A central shaft hole is located at the center of the support disc. Multiple bolt positioning holes are fixedly mounted on the upper surface of the support disc. A crossbeam is positioned above the fixed support, and a hydraulic cylinder is fixedly mounted on the crossbeam. A bolt disc is detachably mounted at the end of the telescopic shaft of the hydraulic cylinder. A shaft hole positioning post is detachably mounted on the bottom surface of the bolt disc and is inserted into the central shaft hole. Multiple bolt hole positioning posts are fixedly mounted on the bottom surface of the bolt disc and are inserted into the bolt positioning holes.

[0008] Preferably, the brake disc is placed on the support disc, the shaft hole positioning post passes through the shaft hole at the center of the brake disc, and the bolt hole positioning post passes through the bolt hole on the brake disc.

[0009] This setting enables the positioning of the brake disc, preventing it from becoming loose during processing.

[0010] Preferably, a side fixing ring is fixedly installed on the side of the support plate, and the side fixing ring is detachably connected to the fixed support by a plurality of fastening bolts.

[0011] This setting facilitates the replacement of the support disc according to different brake disc models.

[0012] Preferably, two vertically arranged positioning protrusions are fixedly installed on the upper surface of the support plate, and the positioning protrusions pass through the remaining two bolt holes on the brake plate for positioning operation;

[0013] This setting serves to initially position the brake disc, making it easier for the subsequent shaft hole positioning pin to be inserted into the central shaft hole and the bolt hole positioning pin to be inserted into the bolt positioning hole.

[0014] Preferably, a fixed plate is fixedly installed at the end of the telescopic shaft of the hydraulic cylinder, and the bolt plate is detachably installed on the bottom surface of the fixed plate by a plurality of fastening screws.

[0015] Preferably, two symmetrical guide posts are fixedly installed on the top surface of the bolt disc, and two symmetrical guide sleeves are fixedly installed on the bottom surface of the crossbeam plate. The guide sleeves are fitted on the guide posts and are slidably connected to the guide posts.

[0016] This feature guides the up-and-down movement of the bolt disc.

[0017] Preferably, a limiting plate is fixedly installed at the top of the shaft hole positioning post, and the limiting plate is detachably installed on the bottom surface of the bolt plate.

[0018] Preferably, a bolt seat is fixedly installed at the top of the bolt hole positioning post, and the bolt seat is detachably installed on the bottom surface of the bolt disc.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model uses a hydraulic cylinder to drive the bolt disc to descend, causing the shaft hole positioning pin to pass through the central shaft hole of the brake disc and insert into the central shaft hole of the support disc. The bolt hole positioning pin passes through the bolt hole of the brake disc and inserts into the bolt positioning hole. With the help of the positioning protrusion on the support disc for initial positioning, the brake disc is positioned quickly and accurately and locked. This replaces the traditional manual operation, reduces labor intensity, improves clamping efficiency, avoids the problem of loosening caused by insufficient clamping force, and ensures machining accuracy.

[0021] 2. This utility model detachably connects the support plate to the fixed support via a side fixing ring, and the bolt plate is detachably connected to the fixed plate of the hydraulic cylinder via fastening screws. The shaft hole positioning post and the bolt hole positioning post are detachably installed on the bolt plate via a limiting plate and a bolt seat, respectively. This realizes the function of replacing corresponding parts according to different models of brake discs, solves the defect of traditional devices that can only clamp constant models of brake discs, and achieves the effect of improving the versatility of the device and production efficiency.

[0022] 3. This utility model provides guidance for the up-and-down movement of the bolt disc by setting guide sleeves on the crossbeam plate and guide posts on the bolt disc, with the guide sleeves and guide posts slidingly engaging. This ensures that the shaft hole positioning posts and bolt hole positioning posts are accurately inserted into their corresponding holes, enhancing the stability of the clamping process. The hydraulic drive of the hydraulic cylinder can stably control the locking force, further ensuring the stability of the brake disc during machining and reducing machining errors caused by clamping problems.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3This utility model provides a technical solution: a hydraulic locking device for quick clamping of a brake disc, including a fixed support 1, a central hole 10 at the center of the fixed support 1, a support plate 11 detachably mounted on the fixed support 1, the support plate 11 being inserted into the central hole 10, a central shaft hole 13 at the center of the support plate 11, and multiple bolt positioning holes 14 fixedly mounted on the upper surface of the support plate 11. A crossbeam plate 2 is provided above the fixed support 1, and a hydraulic cylinder 20 is fixedly mounted on the crossbeam plate 2. A bolt disc 22 is detachably mounted at the end of the telescopic shaft of the hydraulic cylinder 20, and a shaft hole is detachably mounted on the bottom surface of the bolt disc 22. Positioning pin 25, shaft hole positioning pin 25 is inserted into the central shaft hole 13. Multiple bolt hole positioning pins 26 are fixedly installed on the bottom surface of bolt disc 22, and bolt hole positioning pins 26 are inserted into the bolt positioning holes 14. The brake disc is placed on the support disc 11. The shaft hole positioning pin 25 passes through the shaft hole at the center of the brake disc, and the bolt hole positioning pins 26 pass through the bolt holes on the brake disc, so as to realize the positioning operation of the brake disc and prevent the brake disc from loosening during the processing. In addition, with the hydraulic cylinder 20 driving the bolt disc 22 to move downward, the brake disc can be pressed tightly on the support disc 11, which achieves the effect of hydraulic locking.

[0031] like Figure 2 As shown, a side fixing ring 12 is fixedly installed on the side of the support plate 11. The side fixing ring 12 is detachably connected to the fixed support 1 by multiple fastening bolts, which facilitates the replacement of the support plate 11 according to different models of brake discs.

[0032] Specifically, two vertically arranged positioning protrusions 15 are fixedly installed on the upper surface of the support disc 11. The positioning protrusions 15 pass through the remaining two bolt holes on the brake disc for positioning operations, which plays a preliminary role in positioning the brake disc, making it easier for the subsequent shaft hole positioning pin 25 to be inserted into the central shaft hole 13 and the bolt hole positioning pin 26 to be inserted into the bolt positioning hole 14. The sum of the number of positioning protrusions 15 and the number of bolt hole positioning pins 26 is equal to the number of bolt holes on the brake disc, so that the insertion and positioning operation can be performed normally.

[0033] like Figure 3 As shown, a fixed plate 21 is fixedly installed at the end of the telescopic shaft of the hydraulic cylinder 20. The bolt plate 22 is detachably installed on the bottom surface of the fixed plate 21 by multiple fastening screws, so that the bolt plate 22 can be easily installed and removed, achieving the effect of replacing and using different brake discs.

[0034] like Figure 3As shown, two symmetrical guide posts 23 are fixedly installed on the top surface of the bolt disc 22, and two symmetrical guide sleeves 24 are fixedly installed on the bottom surface of the crossbeam plate 2. The guide sleeves 24 are fitted on the guide posts 23 and are slidably connected to the guide posts 23, so as to guide the up and down movement of the bolt disc 22.

[0035] like Figure 3 As shown, a limiting plate 251 is fixedly installed on the top of the shaft hole positioning post 25, and the limiting plate 251 is detachably installed on the bottom surface of the bolt plate 22; a bolt seat 261 is fixedly installed on the top of the bolt hole positioning post 26, and the bolt seat 261 is detachably installed on the bottom surface of the bolt plate 22, so that the shaft hole positioning post 25 and the bolt hole positioning post 26 can also be replaced, so as to achieve the effect of replacement according to different brake discs.

[0036] Finally, it should be noted that the hydraulic cylinder 20, the corresponding control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0037] When using the hydraulic locking device for quick clamping of brake discs of this utility model, select the appropriate support disc 11 according to the brake disc model, and connect it to the fixed support 1 with the side fixing ring 12 by fastening bolts, so that the support disc 11 is inserted into the center hole 10, and the brake disc is placed on the support disc 11, allowing the positioning protrusion 15 to pass through the two corresponding bolt holes on the brake disc to complete the initial positioning.

[0038] Next, replace the corresponding bolt disc 22 and install it on the fixed disc 21 of the telescopic shaft of the hydraulic cylinder 20 by tightening screws. Ensure that the shaft hole positioning post 25 and the bolt hole positioning post 26 match the brake disc hole position. Start the hydraulic cylinder 20, the bolt disc 22 moves down, the guide post 23 slides along the guide sleeve 24, the shaft hole positioning post 25 passes through the brake disc shaft hole and inserts into the central shaft hole 13, and the bolt hole positioning post 26 passes through the brake disc bolt hole and inserts into the bolt positioning hole 14. The hydraulic cylinder 20 continues to apply pressure to complete the locking.

[0039] After processing, the hydraulic cylinder 20 drives the bolt disc 22 to move upward and reset, and the brake disc can be removed. When a change of type is required, the bolt disc 22, support disc 11 and positioning column are disassembled, and the corresponding parts are replaced and the above steps are repeated.
